EXPERT COMMENTARY

Symptomatic vaginal atrophy, also referred to as genitourinary syndrome of menopause (GSM), is common and tends to progress without treatment. When use of over-the-counter lubricants and/or moisturizers are not sufficient to address symptoms, vaginal estrogen has represented the mainstay of treatment for this condition and effectively addresses GSM symptoms.¹ In recent years, some physicians have been offering vaginal carbon dioxide (CO2) laser therapy as an alternative to vaginal estrogen in the treatment of GSM; however, the efficacy of laser therapy in this setting has been uncertain.

Li and colleagues conducted a double-blind randomized trial in postmenopausal women with bothersome vaginal symptoms to compare the efficacy of the fractional CO2 vaginal laser with that of sham treatment.

Details of the study

Investigators (who received no funding from any relevant commercial entity) at a teaching hospital in Sydney, Australia, randomly assigned 85 women with menopausal symptoms suggestive of GSM to laser (n = 43) or sham (n = 42) treatment. Participants underwent 3 treatments at monthly intervals. Laser treatments were performed with standard settings (40-watt power), while sham treatments were conducted with low settings that have no tissue effect. Local anesthesia cream was employed for all procedures, and a plume evacuator was used to remove visual and olfactory effects from laser smoke.

To maintain blinding, different clinicians performed assessments and treatments. Symptom severity assessments were based on a visual analog scale (VAS) and the Vulvovaginal Symptom Questionnaire (VSQ), with a minimal clinically important difference specified as a 50% decrease in severity scores of both assessment tools. Change in severity of symptoms, including dyspareunia, dysuria, vaginal dryness, and burning and itching, was assessed at 12 months. Quality of life, the Vaginal Health Index (VHI) score, and vaginal histology were among the secondary outcomes. In addition, vaginal biopsies were performed at baseline and 6 months after study treatment.

Among the 78 women (91.7%) who completed the 12-month evaluations, the mean age was approximately 57, more than 95% were White, and approximately half were sexually active.

Results. For the laser and sham treatment groups, at 12 months no significant differences were noted for change in overall symptoms or in the most severe symptom. Many participants who received laser or sham treatment reported an improvement in vaginal symptoms 12 months following treatment.

The VAS score for a change in symptom severity in the laser-treated group compared with the sham-treated group was -17.2 versus -26.6, a difference of 9.4 (95% confidence interval [CI], -28.6 to 47.5), while the VAS score for the most severe symptom was -24.5 versus -20.4, a difference of -4.1 (95% CI, -32.5 to 24.3). The VSQ score was, respectively, -3.1 versus -1.6 (difference, -1.5 [95% CI, -5.9 to 3.0]). The mean quality of life score showed no significant differences between the laser and the sham group (6.3 vs 1.4, a difference of 4.8 [95% CI, -3.9 to 13.5]). The VHI score was 0.9 in the laser group versus 1.3 in the sham group, for a difference of -0.4 (95% CI, -4.3 to 3.6). Likewise, the proportion of participants who noted a reduction of more than 50% in bother from their most severe symptoms was similar in the 2 groups. Similarly, changes in vaginal histology were similar in the laser and sham groups.

The proportion of participants who reported adverse events, including transient vaginal discomfort, discharge, or urinary tract symptoms, was similar in the 2 groups.

Study strengths and limitations

Although other randomized studies of fractionated laser therapy for GSM have been reported, this Australian trial is the largest and longest to date and also is the first to have used sham-treated controls.

Breast cancer survivors represent a group of patients for whom treatment of GSM can be a major conundrum—induced menopause that often results when combination chemotherapy is employed in premenopausal survivors can result in severe GSM; use of aromatase inhibitors likewise can cause bothersome GSM symptoms. Since the US Food and Drug Administration lists a personal history of breast cancer as a contraindication to use of any estrogen formulation, breast cancer survivors represent a population targeted by physicians offering vaginal laser treatment. Accordingly, that approximately 50% of trial participants were breast cancer survivors means the investigators were assessing the impact of laser therapy in a population of particular clinical relevance. Of note, as with participants overall, laser therapy when employed in breast cancer survivors did not result in outcomes distinct from sham treatments.² ●

For much of the general public, in-home care from a physician is akin to the rotary telephone: a feature of a bygone age, long since replaced by vastly different systems. While approximately 40% of physician-patient interactions in 1930 were house calls, by the early 1980s this had dwindled to less than 1%,¹ with almost all physician-patient encounters taking place in a clinical setting, whether in a hospital or in a free-standing clinic. In the last 2 decades, a smattering of primary care and medical subspecialty clinicians started to incorporate some in-home care into their practices in the form of telemedicine, using video and telephone technology to facilitate care outside of the clinical setting, and by 2016, approximately 15% of physicians reported using some form of telemedicine in their interactions with patients.²

Despite these advances, prior to the COVID-19 pandemic, obstetricians lagged significantly behind in their use of at-home or remote care. Although there were some efforts to promote a hybrid care model that incorporated prenatal telemedicine,³ pre-pandemic ObGyn was one of the least likely fields to offer telemedicine to their patients, with only 9% of practices offering such services.² In this article, we discuss how the COVID-19 pandemic resulted in a shift from traditional, in-person care to a hybrid remote model and how this may benefit obstetrics patients as well as clinicians.

Pre-pandemic patient management

The traditional model of prenatal care presents a particularly intense time period for patients in terms of its demands. Women who are pregnant and start care in their first trimester typically have 12 to 14 visits during the subsequent 6 to 7 months, with additional visits for those with high-risk pregnancies. Although some of these visits coincide with the need for in-person laboratory work or imaging, many are chiefly oriented around assessment of vital signs or counseling. These frequent prenatal visits represent a significant commitment from patients in terms of transportation, time off work, and childcare resources—all of which may be exacerbated for patients who need to receive their care from overbooked, high-risk specialists.

After delivery, attending an in-person postpartum visit with a newborn can be even more daunting. Despite the increased recognition from professional groups of the importance of postpartum care to support breastfeeding, physical recovery, and mental health, as many as 40% of recently delivered patients do not attend their scheduled postpartum visit(s).⁴ Still, before 2020, few obstetricians had revised their workflows to “meet patients where they are,” with many continuing to only offer in-person care and assessments.

COVID-19: An impetus for change

As with so many things, the COVID-19 pandemic has challenged our ideas of what is normal. In a sense, the pandemic has catalyzed a revolution in the prenatal care model. The very real risks of exposure and contagion during the pandemic—for clinicians and patients alike—has forced ObGyns to reexamine the actual risks and benefits of in-person and in-clinic prenatal care. As a result, many ObGyns have rapidly adopted telemedicine into practices that were strictly in-person. For example, a national survey of 172 clinicians who offered contraception counseling during the pandemic found that 91% of them were now offering telemedicine services, with 78% of those clinicians new to telemedicine.⁵ Similarly, although a minority of surveyed obstetricians in New York City reported using telemedicine pre-pandemic, 89% planned to continue using such technology in the future.⁶

Incorporating mobile technology

Obstetricians, forced to consolidate and maximize their in-person care to protect their patients’ safety, have started to realize that many of the conversations and counseling offered to patients can be managed equally effectively with telemedicine. Furthermore, basic home monitoring devices, such as blood pressure machines, can be safely and accurately used by patients without requiring them to come to the office.

More recent research into mobile medical devices suggests that patients can safely and appropriately manage more complex tools. One such example is a mobile, self-operated, ultrasound transducer that is controlled through a smartphone (Instinct, Pulsenmore Ltd). This device was evaluated in an observational, noninterventional trial of 100 women carrying a singleton fetus at 14/0 weeks’ to 39/6 weeks’ gestation. Patients performed 1,360 self-scans, which were reviewed by a clinician in real time online or subsequently off-line. Results showed successful detection rates of 95.3% for fetal heart activity, 88.3% for body movements, 69.4% for tone, 23.8% for breathing movements, and 92.2% for normal amniotic fluid volume.⁷ The authors concluded that this represents a feasible solution for remote sonographic fetal assessment.

Coordinating care with health care extenders

Remote monitoring options allow patients to be safely monitored during their pregnancies while remaining at home more often, especially when used in conjunction with trained health care extenders such as registered nurses, primary care associates, or “maternity navigators” who can facilitate off-site care. In fact, many aspects of prenatal care are particularly amenable to remote medicine or non–physician-based home care. Different variations of this model of “hybrid” prenatal care may be appropriate depending upon the needs of the patient population served by a given obstetrics practice. Ideally, a prenatal care model personalizes care based on the known risk factors that are identified at the beginning of prenatal care, the anticipated barriers to care, and the patient’s own preferences. As a result, alternatives to the traditional model may be to alternate in-person and telemedicine visits,^3,8 to incorporate in-person or remote group prenatal visits,^9,10 or to incorporate staff with basic health care skills to serve as health care extenders in the community and provide home visits for basic monitoring, laboratory work, and patient education.¹¹

Benefits of hybrid prenatal models

As we look ahead to the end of the pandemic, how should obstetricians view these hybrid prenatal care models? Are these models safe for patients? Were they only worthwhile to minimize infection risk, or do they have potential benefits for patients going forward?

In fact, data on the use of telemedicine in prenatal care indicate that these models may be equally as safe as the traditional model in terms of clinical outcomes and may have important additional benefits with regard to patient convenience and access to and satisfaction with care. Even audio-only prenatal televisits have been found to be equivalent to in-person visits in terms of serious perinatal outcomes.¹² Common pregnancy diagnoses are also well-served by telemedicine. For example, several recent investigations of patients with gestational diabetes have found that telemedicine was as effective as standard care for glucose control.^13,14 Management of hypertension during pregnancy, another antenatal condition that is commonly managed with frequent in-person check-ups, also was found to be adequately feasible with telemedicine using home monitors and symptom checklists, with high rates of patient satisfaction.¹⁵

With good evidence for safety, the added potential for patients to benefit in such hybrid models is multifactorial. For one, despite our collective hopes, the COVID-19 pandemic may have a long tail. Vaccine hesitancy and COVID-19 variants may mean that clinicians will have to consider the real threat of infection risk in the clinic setting for years to come. In-home prenatal care also provides a wide variety of social, economic, and psychological benefits for pregnant women across various patient populations. The pandemic has introduced many patients to the full potential of working and meeting remotely; pregnant patients are becoming more familiar with these technology platforms and appreciate its incorporation into their busy lives.⁵ Furthermore, hybrid models actually can provide otherwise “nonadherent” patients with better access to care. From the patient perspective, an in-person 15-minute health care provider visit actually represents a significant commitment of time and resources (ie, hours spent on public transportation, lost wages for those with inflexible work schedules, and childcare costs for patients discouraged from bringing their children to prenatal visits). Especially for patients with fewer socioeconomic resources, these barriers to in-person clinic visits may be daunting, if not insurmountable; the option of remote visits or house calls reduces these barriers and facilitates care.¹⁶

Such hybrid models benefit prenatal clinicians as well. In addition to a decreased risk of infection, clinicians may be able to attract a wider potential prenatal patient population with telemedicine by appealing to younger and potentially more technology-savvy patients.¹⁷ Importantly, telemedicine is increasingly recognized as on par with in-person visits in many billing algorithms. Changes during the pandemic led Medicare to cover telemedicine visits as well as in-person visits^18,19; among other groundbreaking changes, new patients can have an initial billable visit via telemedicine. Although the billing landscape will likely continue to evolve, such changes allow clinicians to focus on patient safety and convenience without financial risk to their practices.

The future of prenatal appointment scheduling

The future of prenatal care certainly doesn’t look like a dozen 15-minute visits in a private physician’s office. While these emerging hybrid models of prenatal care certainly can benefit patients with low-risk uncomplicated pregnancies, they are already being adopted by clinicians who care for patients with antenatal complications that require specialist consultation; for those with conditions that require frequent, low-complexity check-ins (gestational diabetes, chronic hypertension, history of pre-term birth, etc.); and for patients who struggle with financial or logistical barriers to in-person care. Although obstetrics may have lagged behind other subspecialties in revising its traditional health care models, the pandemic has opened up a new world of possibilities of remote and in-home care for this field. ●

For much of the general public, in-home care from a physician is akin to the rotary telephone: a feature of a bygone age, long since replaced by vastly different systems.

Although some of these visits coincide with the need for in-person laboratory work or imaging, many are chiefly oriented around assessment of vital signs or counseling. These frequent prenatal visits represent a significant commitment from patients in terms of transportation, time off work, and childcare resources—all of which may be exacerbated for patients who need to receive their care from overbooked, high-risk specialists.

After delivery, attending an in-person postpartum visit with a newborn can be even more daunting. Despite the increased recognition from professional groups of the importance of postpartum care to support breastfeeding, physical recovery, and mental health, as many as 40% of recently delivered patients do not attend their scheduled postpartum visit(s).⁴ Still, before 2020, few obstetricians had revised their workflows to “meet patients where they are,” with many continuing to only offer in-person care and assessments.

COVID-19: An impetus for change

As with so many things, the COVID-19 pandemic has challenged our ideas of what is normal. In a sense, the pandemic has catalyzed a revolution in the prenatal care model. The very real risks of exposure and contagion during the pandemic—for clinicians and patients alike—has forced ObGyns to reexamine the actual risks and benefits of in-person and in-clinic prenatal care. As a result, many ObGyns have rapidly adopted telemedicine into practices that were strictly in-person. For example, a national survey of 172 clinicians who offered contraception counseling during the pandemic found that 91% of them were now offering telemedicine services, with 78% of those clinicians new to telemedicine.⁵ Similarly, although a minority of surveyed obstetricians in New York City reported using telemedicine pre-pandemic, 89% planned to continue using such technology in the future.⁶

Incorporating mobile technology

Obstetricians, forced to consolidate and maximize their in-person care to protect their patients’ safety, have started to realize that many of the conversations and counseling offered to patients can be managed equally effectively with telemedicine. Furthermore, basic home monitoring devices, such as blood pressure machines, can be safely and accurately used by patients without requiring them to come to the office.

More recent research into mobile medical devices suggests that patients can safely and appropriately manage more complex tools. One such example is a mobile, self-operated, ultrasound transducer that is controlled through a smartphone (Instinct, Pulsenmore Ltd). This device was evaluated in an observational, noninterventional trial of 100 women carrying a singleton fetus at 14/0 weeks’ to 39/6 weeks’ gestation. Patients performed 1,360 self-scans, which were reviewed by a clinician in real time online or subsequently off-line. Results showed successful detection rates of 95.3% for fetal heart activity, 88.3% for body movements, 69.4% for tone, 23.8% for breathing movements, and 92.2% for normal amniotic fluid volume.⁷ The authors concluded that this represents a feasible solution for remote sonographic fetal assessment.

Coordinating care with health care extenders

Remote monitoring options allow patients to be safely monitored during their pregnancies while remaining at home more often, especially when used in conjunction with trained health care extenders such as registered nurses, primary care associates, or “maternity navigators” who can facilitate off-site care. In fact, many aspects of prenatal care are particularly amenable to remote medicine or non–physician-based home care. Different variations of this model of “hybrid” prenatal care may be appropriate depending upon the needs of the patient population served by a given obstetrics practice. Ideally, a prenatal care model personalizes care based on the known risk factors that are identified at the beginning of prenatal care, the anticipated barriers to care, and the patient’s own preferences. As a result, alternatives to the traditional model may be to alternate in-person and telemedicine visits,^3,8 to incorporate in-person or remote group prenatal visits,^9,10 or to incorporate staff with basic health care skills to serve as health care extenders in the community and provide home visits for basic monitoring, laboratory work, and patient education.¹¹

Benefits of hybrid prenatal models

As we look ahead to the end of the pandemic, how should obstetricians view these hybrid prenatal care models? Are these models safe for patients? Were they only worthwhile to minimize infection risk, or do they have potential benefits for patients going forward?

In fact, data on the use of telemedicine in prenatal care indicate that these models may be equally as safe as the traditional model in terms of clinical outcomes and may have important additional benefits with regard to patient convenience and access to and satisfaction with care. Even audio-only prenatal televisits have been found to be equivalent to in-person visits in terms of serious perinatal outcomes.¹² Common pregnancy diagnoses are also well-served by telemedicine. For example, several recent investigations of patients with gestational diabetes have found that telemedicine was as effective as standard care for glucose control.^13,14 Management of hypertension during pregnancy, another antenatal condition that is commonly managed with frequent in-person check-ups, also was found to be adequately feasible with telemedicine using home monitors and symptom checklists, with high rates of patient satisfaction.¹⁵

With good evidence for safety, the added potential for patients to benefit in such hybrid models is multifactorial. For one, despite our collective hopes, the COVID-19 pandemic may have a long tail. Vaccine hesitancy and COVID-19 variants may mean that clinicians will have to consider the real threat of infection risk in the clinic setting for years to come. In-home prenatal care also provides a wide variety of social, economic, and psychological benefits for pregnant women across various patient populations. The pandemic has introduced many patients to the full potential of working and meeting remotely; pregnant patients are becoming more familiar with these technology platforms and appreciate its incorporation into their busy lives.⁵ Furthermore, hybrid models actually can provide otherwise “nonadherent” patients with better access to care. From the patient perspective, an in-person 15-minute health care provider visit actually represents a significant commitment of time and resources (ie, hours spent on public transportation, lost wages for those with inflexible work schedules, and childcare costs for patients discouraged from bringing their children to prenatal visits). Especially for patients with fewer socioeconomic resources, these barriers to in-person clinic visits may be daunting, if not insurmountable; the option of remote visits or house calls reduces these barriers and facilitates care.¹⁶

Such hybrid models benefit prenatal clinicians as well. In addition to a decreased risk of infection, clinicians may be able to attract a wider potential prenatal patient population with telemedicine by appealing to younger and potentially more technology-savvy patients.¹⁷ Importantly, telemedicine is increasingly recognized as on par with in-person visits in many billing algorithms. Changes during the pandemic led Medicare to cover telemedicine visits as well as in-person visits^18,19; among other groundbreaking changes, new patients can have an initial billable visit via telemedicine. Although the billing landscape will likely continue to evolve, such changes allow clinicians to focus on patient safety and convenience without financial risk to their practices.

The future of prenatal appointment scheduling

The future of prenatal care certainly doesn’t look like a dozen 15-minute visits in a private physician’s office. While these emerging hybrid models of prenatal care certainly can benefit patients with low-risk uncomplicated pregnancies, they are already being adopted by clinicians who care for patients with antenatal complications that require specialist consultation; for those with conditions that require frequent, low-complexity check-ins (gestational diabetes, chronic hypertension, history of pre-term birth, etc.); and for patients who struggle with financial or logistical barriers to in-person care. Although obstetrics may have lagged behind other subspecialties in revising its traditional health care models, the pandemic has opened up a new world of possibilities of remote and in-home care for this field. ●

In this question-and-answer article (the first in a series), our objective is to reinforce for the clinician several practical points of management for common infectious diseases. The principal references for the answers to the questions are 2 textbook chapters written by Dr. Duff.^1,2 Other pertinent references are included in the text.

1. What are the best tests for the diagnosis of congenital cytomegalovirus (CMV) infection?

When congenital CMV is suspected, if the patient is at least 15 weeks’ gestation, an amniocentesis should be performed to test for CMV DNA in the amniotic fluid using polymerase chain reaction (PCR) methodology. If the initial test is negative, amniocentesis should be repeated in approximately 4 weeks. Coincident with amniocentesis, a detailed ultrasound examination should be performed to search for findings suggestive of fetal injury, such as growth restriction, microcephaly, periventricular calcifications, hepatosplenomegaly, echogenic bowel, and serous effusions in the pleural space or abdomen.

2. Which major organisms cause urinary tract infections (UTIs) in women?

The most common causative organism is Escherichia coli, which is responsible for approximately 70% of all UTIs. Klebsiella pneumoniae and Proteus species are the 2 other aerobic gram-negative bacilli that are common uropathogens. In addition, 3 gram-positive cocci are important: enterococci, Staphylococcus saprophyticus, and group B streptococcus.

3. What are the major complications of pyelonephritis in pregnancy?

Pyelonephritis is an important cause of preterm labor, sepsis, and adult respiratory distress syndrome. Most cases of pyelonephritis develop as a result of an untreated or inadequately treated lower urinary tract infection.

4. What is the most ominous manifestation of congenital parvovirus infection, and what is the cause of this abnormality?

Hydrops fetalis is the most ominous complication of congenital parvovirus infection. The virus crosses the placenta and attacks red cell progenitor cells, resulting in an aplastic anemia. In addition, the virus may cause myocarditis that, in turn, may result in cardiac failure in the fetus.

5. What are the major manifestations of congenital rubella syndrome?

Rubella is one of the most highly teratogenic of all the viral infections, particularly when maternal infection occurs in the first trimester. Manifestations of congenital rubella include hearing deficits, cataracts, glaucoma, microcephaly, mental retardation, cardiac malformations such as patent ductus arteriosus and pulmonic stenosis, and growth restriction.

6. Which vaccines are contraindicated in pregnancy?

Live virus vaccines should not be used in pregnancy because of the possibility of teratogenic effects. Live agents include the measles, mumps, and rubella (MMR) vaccine; live influenza vaccine (FluMist); oral polio vaccine; BCG (bacille Calmette-Guerin) vaccine; yellow fever vaccine; and smallpox vaccine.

7. What is the most appropriate treatment for trichomonas infection in pregnancy?

Trichomonas infection should be treated with oral metronidazole 500 mg twice daily for 7 days. Metronidazole also can be given as a single oral 2-g dose. This treatment is not quite as effective as the multidose regimen, but it may be appropriate for patients who are not likely to be adherent with the longer course of treatment.

Resistance to metronidazole is rare; in such instances, oral tinidazole 2 g in a single dose may be effective.

8. For uncomplicated gonorrhea in a pregnant woman, what is the most appropriate treatment?

The current recommendation from the Centers for Disease Control and Prevention for treatment of uncomplicated gonorrhea is a single 500-mg intramuscular dose of ceftriaxone. For the patient who is opposed to an intramuscular injection, an alternative treatment is cefixime 800 mg orally. With either of these regimens, if chlamydia infection cannot be excluded, the pregnant patient also should receive azithromycin 1,000 mg orally in a single dose. In a nonpregnant patient, doxycycline 100 mg orally twice daily for 7 days should be used to cover for concurrent chlamydia infection.

In a patient with an allergy to β-lactam antibiotics, an alternative regimen for treatment of uncomplicated gonorrhea is intramuscular gentamicin 240 mg plus a single 2,000-mg dose of oral azithromycin. (St Cyr S, Barbee L, Workowski KA, et al. Update to CDC’s treatment guidelines for gonococcal infection, 2020. MMWR Morbid Mortal Wkly Rep. 2020;69:1911-1916.) ●

The social reckoning of 2020 has led to many discussions and conversations around equity and disparities. With the COVID-19 pandemic, there has been a particular spotlight on health care disparities and race-based medicine. Racism in medicine is pervasive; little has been done over the years to dismantle and unlearn practices that continue to contribute to existing gaps and disparities. Race and ethnicity are both social constructs that have long been used within medical practice and in dictating the type of care an individual receives. Without a universal definition, race, ethnicity, and ancestry have long been used interchangeably within medicine and society. Appreciating that race and ethnicity-based constructs can have other social implications in health care, with their impact on structural racism beyond health care settings, these constructs may still be part of assessments and key modifiers to understanding health differences. It is imperative that medical providers examine the use of race and ethnicity within the care that they provide.

While racial determinants of health cannot be removed from historical access, utilization, and barriers related to reproductive care, guidelines structured around historical ethnicity and race further restrict universal access to carrier screening and informed reproductive testing decisions.

Carrier screening

The goal of preconception and prenatal carrier screening is to provide individuals and reproductive partners with information to optimize pregnancy outcomes based on personal values and preferences.¹ The practice of carrier screening began almost half a century ago with screening for individual conditions seen more frequently in certain populations, such as Tay-Sachs disease in those of Ashkenazi Jewish descent and sickle cell disease in those of African descent. Cystic fibrosis carrier screening was first recommended for individuals of Northern European descent in 2001 before being recommended for pan ethnic screening a decade later. Other individual conditions are also recommended for screening based on race/ethnicity (eg, Canavan disease in the Ashkenazi Jewish population, Tay-Sachs disease in individuals of Cajun or French-Canadian descent).^2-4 Practice guidelines from professional societies recommend offering carrier screening for individual conditions based on condition severity, race or ethnicity, prevalence, carrier frequency, detection rates, and residual risk.¹ However, this process can be problematic, as the data frequently used in updating guidelines and recommendations come primarily from studies and databases where much of the cohort is White.^5,6 Failing to identify genetic associations in diverse populations limits the ability to illuminate new discoveries that inform risk management and treatment, especially for populations that are disproportionately underserved in medicine.⁷

Need for expanded carrier screening

The evolution of genomics and technology within the realm of carrier screening has enabled the simultaneous screening for many serious Mendelian diseases, known as expanded carrier screening (ECS). A 2016 study illustrated that, in most racial/ethnic categories, the cumulative risk of severe and profound conditions found on ECS panels outside the guideline recommendations are greater than the risk identified by guideline-based panels.⁸ Additionally, a 2020 study showed that self-reported ethnicity was an imperfect indicator of genetic ancestry, with 9% of those in the cohort having a >50% genetic ancestry from a lineage inconsistent with their self-reported ethnicity.⁹ Data over the past decade have established the clinical utility,¹⁰ clinical validity,¹¹ analytical validity,¹² and cost-effectiveness¹³ of pan-ethnic ECS. In 2021, American College of Medical Genetics and Genomics (ACMG) recommended a panel of pan-ethnic conditions that should be offered to all patients due to smaller ethnicity-based panels failing to provide equitable evaluation of all racial and ethnic groups.¹⁴ The guidelines from the American College of Obstetricians and Gynecologists (ACOG) fall short of recommending that ECS be offered to all individuals in lieu of screening based on self-reported ethnicity.^3,4

Phasing out ethnicity-based carrier screening

This begs the question: Do race, ethnicity, or ancestry have a role in carrier screening? While each may have had a role at the inception of offering carrier screening due to high costs of technology, recent studies have shown the limitations of using self-reported ethnicity in screening. Guideline-based carrier screenings miss a significant percentage of pregnancies (13% to 94%) affected by serious conditions on expanded carrier screening panels.⁸ Additionally, 40% of Americans cannot identify the ethnicity of all 4 grandparents.¹⁵

Founder mutations due to ancestry patterns are still present; however, stratification of care should only be pursued when the presence or absence of these markers would alter clinical management. While the reproductive risk an individual may receive varies based on their self-reported ethnicity, the clinically indicated follow-up testing is the same: offering carrier screening for the reproductive partner or gamete donor. With increased detection rates via sequencing for most autosomal recessive conditions, if the reproductive partner or gamete donor is not identified as a carrier, no further testing is generally indicated regardless of ancestry. Genotyping platforms should not be used for partner carrier screening as they primarily target common pathogenic variants based on dominant ancestry groups and do not provide the same risk reduction.

Continue to: Variant reporting...

We have long known that databases and registries in the United States have an increased representation of individuals from European ancestries.^5,6 However, there have been limited conversations about how the lack of representation within our databases and registries leads to inequities in guidelines and the care that we provide to patients. As a result, studies have shown higher rates of variants of uncertain significance (VUS) identified during genetic testing in non-White individuals than in Whites.¹⁶ When it comes to reporting of variants, carrier screening laboratories follow guidelines set forth by the ACMG, and most laboratories only report likely pathogenic or pathogenic variants.¹⁷ It is unknown how the higher rate of VUSs in the non-White population, and lack of data and representation in databases and software used to calculate predicted phenotype, impacts identification of at-risk carrier couples in these underrepresented populations. It is imperative that we increase knowledge and representation of variants across ethnicities to improve sensitivity and specificity across the population and not just for those of European descent.

Moving forward

Being aware of social- and race-based biases in carrier screening is important, but modifying structural systems to increase representation, access, and utility of carrier screening is a critical next step. Organizations like ACOG and ACMG have committed not only to understanding but also to addressing factors that have led to disparities and inequities in health care delivery and access.^18,19 Actionable steps include offering a universal carrier screening program to all preconception and prenatal patients that addresses conditions with increased carrier frequency, in any population, defined as severe and moderate phenotype with established natural history.^3,4 Educational materials should be provided to detail risks, benefits, and limitations of carrier screening, as well as shared decision making between patient and provider to align the patient’s wishes for the information provided by carrier screening.

A broader number of conditions offered through carrier screening will increase the likelihood of positive carrier results. The increase in carriers identified should be viewed as more accurate reproductive risk assessment in the context of equitable care, rather than justification for panels to be limited to specific ancestries. Simultaneous or tandem reproductive partner or donor testing can be considered to reduce clinical workload and time for results return.

In addition, increased representation of individuals who are from diverse ancestries in promotional and educational resources can reinforce that risk for Mendelian conditions is not specific to single ancestries or for targeted conditions. Future research should be conducted to examine the role of racial disparities related to carrier screening and greater inclusion and recruitment of diverse populations in data sets and research studies.

Learned biases toward race, religion, gender identity, sexual orientation, and economic status in the context of carrier screening should be examined and challenged to increase access for all patients who may benefit from this testing. For example, the use of gendered language within carrier screening guidelines and policies and how such screening is offered to patients should be examined. Guidelines do not specify what to do when someone is adopted, for instance, or does not know their ethnicity. It is important that, as genomic testing becomes more available, individuals and groups are not left behind and existing gaps are not further widened. Assessing for genetic variation that modifies for disease or treatment will be more powerful than stratifying based on race. Carrier screening panels should be comprehensive regardless of ancestry to ensure coverage for global genetic variation and to increase access for all patients to risk assessments that promote informed reproductive decision making.

Health equity requires unlearning certain behaviors

As clinicians we all have a commitment to educate and empower one another to offer care that helps promote health equity. Equitable care requires us to look at the current gaps and figure out what programs and initiatives need to be designed to address those gaps. Carrier screening is one such area in which we can work together to improve the overall care that our patients receive, but it is imperative that we examine our practices and unlearn behaviors that contribute to existing disparities. ●

Organizations like ACOG and ACMG have committed not only to understanding but also to addressing factors that have led to disparities and inequities in health care delivery and access.^18,19 Actionable steps include offering a universal carrier screening program to all preconception and prenatal patients that addresses conditions with increased carrier frequency, in any population, defined as severe and moderate phenotype with established natural history.^3,4 Educational materials should be provided to detail risks, benefits, and limitations of carrier screening, as well as shared decision making between patient and provider to align the patient’s wishes for the information provided by carrier screening.

A broader number of conditions offered through carrier screening will increase the likelihood of positive carrier results. The increase in carriers identified should be viewed as more accurate reproductive risk assessment in the context of equitable care, rather than justification for panels to be limited to specific ancestries. Simultaneous or tandem reproductive partner or donor testing can be considered to reduce clinical workload and time for results return.

In addition, increased representation of individuals who are from diverse ancestries in promotional and educational resources can reinforce that risk for Mendelian conditions is not specific to single ancestries or for targeted conditions. Future research should be conducted to examine the role of racial disparities related to carrier screening and greater inclusion and recruitment of diverse populations in data sets and research studies.

Learned biases toward race, religion, gender identity, sexual orientation, and economic status in the context of carrier screening should be examined and challenged to increase access for all patients who may benefit from this testing. For example, the use of gendered language within carrier screening guidelines and policies and how such screening is offered to patients should be examined. Guidelines do not specify what to do when someone is adopted, for instance, or does not know their ethnicity. It is important that, as genomic testing becomes more available, individuals and groups are not left behind and existing gaps are not further widened. Assessing for genetic variation that modifies for disease or treatment will be more powerful than stratifying based on race. Carrier screening panels should be comprehensive regardless of ancestry to ensure coverage for global genetic variation and to increase access for all patients to risk assessments that promote informed reproductive decision making.

Health equity requires unlearning certain behaviors

As clinicians we all have a commitment to educate and empower one another to offer care that helps promote health equity. Equitable care requires us to look at the current gaps and figure out what programs and initiatives need to be designed to address those gaps. Carrier screening is one such area in which we can work together to improve the overall care that our patients receive, but it is imperative that we examine our practices and unlearn behaviors that contribute to existing disparities. ●

The social reckoning of 2020 has led to many discussions and conversations around equity and disparities. With the COVID-19 pandemic, there has been a particular spotlight on health care disparities and race-based medicine. Racism in medicine is pervasive; little has been done over the years to dismantle and unlearn practices that continue to contribute to existing gaps and disparities. Race and ethnicity are both social constructs that have long been used within medical practice and in dictating the type of care an individual receives. Without a universal definition, race, ethnicity, and ancestry have long been used interchangeably within medicine and society. Appreciating that race and ethnicity-based constructs can have other social implications in health care, with their impact on structural racism beyond health care settings, these constructs may still be part of assessments and key modifiers to understanding health differences. It is imperative that medical providers examine the use of race and ethnicity within the care that they provide.

While racial determinants of health cannot be removed from historical access, utilization, and barriers related to reproductive care, guidelines structured around historical ethnicity and race further restrict universal access to carrier screening and informed reproductive testing decisions.

Carrier screening

The goal of preconception and prenatal carrier screening is to provide individuals and reproductive partners with information to optimize pregnancy outcomes based on personal values and preferences.¹ The practice of carrier screening began almost half a century ago with screening for individual conditions seen more frequently in certain populations, such as Tay-Sachs disease in those of Ashkenazi Jewish descent and sickle cell disease in those of African descent. Cystic fibrosis carrier screening was first recommended for individuals of Northern European descent in 2001 before being recommended for pan ethnic screening a decade later. Other individual conditions are also recommended for screening based on race/ethnicity (eg, Canavan disease in the Ashkenazi Jewish population, Tay-Sachs disease in individuals of Cajun or French-Canadian descent).^2-4 Practice guidelines from professional societies recommend offering carrier screening for individual conditions based on condition severity, race or ethnicity, prevalence, carrier frequency, detection rates, and residual risk.¹ However, this process can be problematic, as the data frequently used in updating guidelines and recommendations come primarily from studies and databases where much of the cohort is White.^5,6 Failing to identify genetic associations in diverse populations limits the ability to illuminate new discoveries that inform risk management and treatment, especially for populations that are disproportionately underserved in medicine.⁷

Need for expanded carrier screening

The evolution of genomics and technology within the realm of carrier screening has enabled the simultaneous screening for many serious Mendelian diseases, known as expanded carrier screening (ECS). A 2016 study illustrated that, in most racial/ethnic categories, the cumulative risk of severe and profound conditions found on ECS panels outside the guideline recommendations are greater than the risk identified by guideline-based panels.⁸ Additionally, a 2020 study showed that self-reported ethnicity was an imperfect indicator of genetic ancestry, with 9% of those in the cohort having a >50% genetic ancestry from a lineage inconsistent with their self-reported ethnicity.⁹ Data over the past decade have established the clinical utility,¹⁰ clinical validity,¹¹ analytical validity,¹² and cost-effectiveness¹³ of pan-ethnic ECS. In 2021, American College of Medical Genetics and Genomics (ACMG) recommended a panel of pan-ethnic conditions that should be offered to all patients due to smaller ethnicity-based panels failing to provide equitable evaluation of all racial and ethnic groups.¹⁴ The guidelines from the American College of Obstetricians and Gynecologists (ACOG) fall short of recommending that ECS be offered to all individuals in lieu of screening based on self-reported ethnicity.^3,4

Phasing out ethnicity-based carrier screening

This begs the question: Do race, ethnicity, or ancestry have a role in carrier screening? While each may have had a role at the inception of offering carrier screening due to high costs of technology, recent studies have shown the limitations of using self-reported ethnicity in screening. Guideline-based carrier screenings miss a significant percentage of pregnancies (13% to 94%) affected by serious conditions on expanded carrier screening panels.⁸ Additionally, 40% of Americans cannot identify the ethnicity of all 4 grandparents.¹⁵

Founder mutations due to ancestry patterns are still present; however, stratification of care should only be pursued when the presence or absence of these markers would alter clinical management. While the reproductive risk an individual may receive varies based on their self-reported ethnicity, the clinically indicated follow-up testing is the same: offering carrier screening for the reproductive partner or gamete donor. With increased detection rates via sequencing for most autosomal recessive conditions, if the reproductive partner or gamete donor is not identified as a carrier, no further testing is generally indicated regardless of ancestry. Genotyping platforms should not be used for partner carrier screening as they primarily target common pathogenic variants based on dominant ancestry groups and do not provide the same risk reduction.

Continue to: Variant reporting...

We have long known that databases and registries in the United States have an increased representation of individuals from European ancestries.^5,6 However, there have been limited conversations about how the lack of representation within our databases and registries leads to inequities in guidelines and the care that we provide to patients. As a result, studies have shown higher rates of variants of uncertain significance (VUS) identified during genetic testing in non-White individuals than in Whites.¹⁶ When it comes to reporting of variants, carrier screening laboratories follow guidelines set forth by the ACMG, and most laboratories only report likely pathogenic or pathogenic variants.¹⁷ It is unknown how the higher rate of VUSs in the non-White population, and lack of data and representation in databases and software used to calculate predicted phenotype, impacts identification of at-risk carrier couples in these underrepresented populations. It is imperative that we increase knowledge and representation of variants across ethnicities to improve sensitivity and specificity across the population and not just for those of European descent.

Short-term hormonal contraceptives remain the most popular class of reversible contraceptives in the United States, despite the availability of longer-acting methods. Oral contraceptives (OCs), contraceptive patches, and contraceptive vaginal rings are extensively used not only because these methods are easy to initiate but also because their ongoing use remains under the control of the woman herself and also provides her with a wide range of important noncontraceptive benefits.

Despite the more than 60 years of innovation that have made hormonal contraceptives safer, more tolerable, and more convenient, there has been room for improvement. Over the last few years, 4 new hormonal methods have been introduced, and each addresses different limitations and problems associated with the existing, often generic, products.

Compared with the traditional norethindrone pill (Micronor and generics), a new drospirenone progestin-only pill (POP) increases ovulation suppression, offers an improved cyclical bleeding profile, and relaxes the tight missed-pill rules that are usually associated with POPs.

In contrast with the older norelgestromin patch (Evra, Xulane), a new contraceptive transdermal patch significantly decreases total estrogen exposure and pairs its estrogen with levonorgestrel, the progestin associated with the lowest venous thromboembolism (VTE) risk in combined hormonal pills.

While existing combination OCs are formulated with the potent estrogen ethinyl estradiol (EE), a new combination pill, formulated with estetrol (E4) and drospirenone, introduces the first new estrogen (estetrol) used in a contraceptive in more than 50 years. Estetrol, a native estrogen, has selective tissue activity with minimal hepatic and breast impacts. Combined with drospirenone, this formulation offers women good contraceptive efficacy and bleeding patterns.

A new contraceptive vaginal ring introduces a new long-acting, specific progestin (segesterone acetate) and pairs it with low-dose EE. These hormones are packaged in a soft vaginal ring that provides up to 13 cycles of contraceptive protection (3 weeks in/1 week out) with one ring, greatly increasing convenience for women.

Each of these new products represents important incremental improvement over existing options.

Continue to: 1. The drospirenone-only OC...

The new POP with drospirenone 4 mg (Slynd), which received US Food and Drug Administration (FDA) approval in 2019, is packaged in a 24/4 formulation (24 hormonally active tablets followed by 4 inactive tablets). This formulation results in more predictable bleeding than does the 0.35-mg norethindrone POP, which contains 28 hormonally active tablets in each pack. In the US clinical trials of drospirenone 4 mg, scheduled bleeding decreased from 81% in cycle 1 to 20% in cycle 13. Unscheduled spotting and bleeding decreased from 61% to 40% in the same timeframe. Notably, this bleeding pattern was well tolerated; only 0.4% of trial participants discontinued this drospirenone POP due to problems with irregular bleeding or amenorrhea.

In contrast to the continuous norethindrone POP, which is not sufficiently dosed to consistently suppress ovulation, the 4-mg daily dose of drospirenone in this new POP is higher than the 3 mg used in commonly prescribed combination OCs that contain EE and drospirenone. This results in a POP that has more consistent ovulation suppression. Because this drospirenone POP is appropriately dosed and based on a longer-acting progestin, it is more forgiving of inconsistent pill taking. Accordingly, the missed-pill rules for this pill are the same as with combination estrogen-progestin OCs.¹ The package labeling cites a first-year failure rate of 4%, but this includes unconfirmed pregnancies. The Pearl Index from the North American trials, based on confirmed pregnancies in nonbreastfeeding women, was 2.9.²

The package labeling for this drospirenone POP includes few contraindications. Conditions that preclude use include the US Medical Eligibility Criteria for contraception Category 4 condition (breast cancer in the last 5 years), renal impairment, and adrenal insufficiency. Other standard contraindications are listed in the prescribing information. Serum potassium levels should be checked (one time only) in the first cycle only for women who chronically use medications that could cause hyperkalemia, such as nonsteroidal anti-inflammatory drugs.

Given the ovulation suppression associated with this drospirenone POP, the safety of a progestin-only method, and the persistent popularity of OC pills, this pill should greatly increase the use of POPs beyond their traditional niche of postpartum and breastfeeding women. The advent of the drospirenone POP means that clinicians now have better options for women who have contraindications to estrogen and desire to control their own contraceptive use. It would be a logical consideration for over-the-counter accessibility.

2. Transdermal patch with ethinyl estradiol/levonorgestrel

The new EE/levonorgestrel transdermal contraceptive patch (Twirla) is soft and flexible, about the same size as other contraceptive patches, and contains EE 2.3 mg/levonorgestrel 2.6 mg. It provides total estrogen exposure that is similar to that of OCs with EE 30 µg and distinctly lower than estrogen levels seen with the original norelgestromin-containing patch or its 2 subsequent generic versions.³ This EE/levonorgestrel patch uses a new 5-layer drug delivery system that focuses the steroids for absorption beneath the patch; there is no peripheral spread of drug around the patch (FIGURE 1).

Transdermal patches offer the convenience of once-a-week dosing. One patch is used each week for 3 consecutive weeks followed by a patch-free week. Patches can be worn on the abdomen, buttock, or trunk (except breasts). Patches should not be placed consecutively on the same site; after a week’s rest, however, the first site can be reused. All transdermal contraceptive products are indicated for use only by women with a body mass index (BMI) <30 kg/m².⁴

While no head-to-head trials have compared this new lower-dose patch with older patches, each patch was compared against a standardized pill, so meaningful comparisons can be made.

In each case, the circulating estrogen levels associated with use of the EE/levonorgestrel patch were considerably lower than those of the comparator pill, while the older norelgestromin patch consistently delivered higher total estrogen levels than its 35-µg comparator pill (TABLE).³ Along these lines, no VTE events occurred in women in the clinical trial of the new patch among women with a BMI <30 kg/m².⁴

Women with a BMI <25 kg/m² experienced lower Pearl Index (PI) pregnancy rates (3.5%) compared with women with a BMI between 25 and 30 kg/m² (5.7%), according to clinical trial data cited in the package labeling. All the modern PI criteria were used to calculate these failure rates. Cycles in which no coitus occurred were excluded. Similarly, cycles in which another contraceptive method (for example, condoms) was added (even once) were excluded. Frequent pregnancy testing was done in the study centers and by the women at home. Bleeding patterns were well accepted; only 2.2% of study participants exited the study early due to menstrual disorders of any kind. Similarly, 3.1% of women discontinued use because of application site disorders. Women should be advised to press down on the patch edges after emerging from water exposure. Replacement patches are rapidly available from the manufacturer should permanent complete patch detachment occur.

Larger-scale phase 4 trials will be conducted to study the impact of this lower-dose patch on VTE rates.

Continue to: 3. A 1-year contraceptive vaginal ring...

The need to obtain new supplies every month or every 3 months contributes to high rates of contraceptive failure and unintended pregnancy among women using short-acting hormonal contraceptives (pills, patches, and vaginal rings).⁵ A woman-controlled contraceptive that would provide 1 year of protection against unintended pregnancy represents a step forward. A contraceptive vaginal ring (CVR) that releases the novel progestin segesterone acetate and EE provides woman-controlled contraception for up to 1 year. This CVR (Annovera) received FDA approval in 2018 and has been marketed in the United States since 2020.

The segesterone acetate/EE CVR is a soft, flexible ring that is opaque white in color and fabricated from nonbiodegradable silicone (FIGURE 2). The outside diameter is 5.6 cm, compared with the 5.4-cm outer diameter of the etonogestrel/EE vaginal ring (NuvaRing). The segesterone acetate/EE CVR has 2 channels: one releases segesterone acetate only and the other releases segesterone acetate and EE. In contrast with the etonogestrel/EE CVR, the segesterone acetate/EE CVR does not need to be refrigerated when stored.⁶

4. An OC with a novel estrogen

Even as use of intrauterine devices and contraceptive implants continues to grow, OCs remain the reversible contraceptive most used by US women. While OCs have been widely studied and represent a safe method of contraception for most reproductive-age women, combination estrogen-progestin OCs are well recognized to increase the risk of VTE. Although the primary role of the progestin component of combination OCs is to suppress ovulation, estrogen is included in combination OCs to stimulate endometrial proliferation, thereby causing predictable bleeding. EE, the potent synthetic estrogen used in the great majority of current OC formulations, induces hepatic production of prothrombotic proteins while inhibiting synthesis of antithrombotic proteins. While the lower EE doses (10–35 µg) in today’s OC formulations are associated with a lower VTE risk than older OCs that contained higher doses of estrogen, VTE continues to represent the principal health risk associated with use of combination OCs. Accordingly, development of a combination OC that has less impact on risk of VTE would be appealing.

In April 2021, the FDA approved an OC formulation that combines 15 mg of the novel estrogen estetrol with 3 mg of drospirenone (Nextstellis). This dose of drospirenone is the same as that used in commonly prescribed EE/drospirenone OC formulations. Also known as E4, estetrol is a natural estrogen synthesized by the fetal liver. Plant-derived E4 is used in this new OC.

Depending on the tissue, E4 acts differently than other estrogens. Similar to other estrogens, E4 acts as an agonist on the nuclear receptor to produce beneficial effects in bone, vaginal mucosa, and heart.⁸ Unlike other estrogens, E4 inhibits proliferation of mammary gland cells and has a neutral impact on the liver.⁹

In contrast with EE, E4 is not inhibited by the liver’s P450 enzymes; accordingly, the risk of drug-drug interactions is reduced. Because E4 is primarily excreted through the urine and not through the biliary tract, the risk of gallstone formation may be lower than with an EE OC. Likewise, E4 has substantially less impact on triglycerides, which are increased with EE. Finally, because of E4’s reduced effect on the liver, the impact on clotting parameters is less than that observed with an OC formulated with EE.¹⁰ This latter observation raises the possibility that VTE risk is lower with the E4/drospirenone OC than an OC formulated with EE.

A 13-cycle phase 3 trial of the E4/drospirenone OC conducted in the United States and Canada enrolled 1,864 women aged 16 to 50 years, including 1,674 who were aged 16 to 35 years.¹¹ Among women in this latter age group, the PI was 2.65 per 100 woman-years. Bleeding/cycle control patterns were similar to those observed in recent trials of other combination contraceptives. Likewise, the proportion of trial participants who discontinued the study due to adverse effects was similar to or lower than that noted in recent trials of other combination contraceptives. Of particular note, no cases of VTE were noted among trial participants of any BMI, a finding which contrasts with recent phase 3 trials of other combination contraceptives. The result of this pivotal trial suggests that the theoretic advantages of E4 when used in a combination OC formulation may translate into a safer, effective, and well-tolerated contraceptive.

Refinements in hormonal contraceptives continue

The 4 new short-acting hormonal contraceptives we reviewed represent enhancements on existing pills, patches, and rings. We hope that, financially, women will have access to these innovative methods and, in particular, that third-party payers will facilitate women’s access to these enhanced short-acting hormonal contraceptives. ●

Short-term hormonal contraceptives remain the most popular class of reversible contraceptives in the United States, despite the availability of longer-acting methods. Oral contraceptives (OCs), contraceptive patches, and contraceptive vaginal rings are extensively used not only because these methods are easy to initiate but also because their ongoing use remains under the control of the woman herself and also provides her with a wide range of important noncontraceptive benefits.

Despite the more than 60 years of innovation that have made hormonal contraceptives safer, more tolerable, and more convenient, there has been room for improvement. Over the last few years, 4 new hormonal methods have been introduced, and each addresses different limitations and problems associated with the existing, often generic, products.

Compared with the traditional norethindrone pill (Micronor and generics), a new drospirenone progestin-only pill (POP) increases ovulation suppression, offers an improved cyclical bleeding profile, and relaxes the tight missed-pill rules that are usually associated with POPs.

In contrast with the older norelgestromin patch (Evra, Xulane), a new contraceptive transdermal patch significantly decreases total estrogen exposure and pairs its estrogen with levonorgestrel, the progestin associated with the lowest venous thromboembolism (VTE) risk in combined hormonal pills.

While existing combination OCs are formulated with the potent estrogen ethinyl estradiol (EE), a new combination pill, formulated with estetrol (E4) and drospirenone, introduces the first new estrogen (estetrol) used in a contraceptive in more than 50 years. Estetrol, a native estrogen, has selective tissue activity with minimal hepatic and breast impacts. Combined with drospirenone, this formulation offers women good contraceptive efficacy and bleeding patterns.

A new contraceptive vaginal ring introduces a new long-acting, specific progestin (segesterone acetate) and pairs it with low-dose EE. These hormones are packaged in a soft vaginal ring that provides up to 13 cycles of contraceptive protection (3 weeks in/1 week out) with one ring, greatly increasing convenience for women.

Each of these new products represents important incremental improvement over existing options.

Continue to: 1. The drospirenone-only OC...

The new POP with drospirenone 4 mg (Slynd), which received US Food and Drug Administration (FDA) approval in 2019, is packaged in a 24/4 formulation (24 hormonally active tablets followed by 4 inactive tablets). This formulation results in more predictable bleeding than does the 0.35-mg norethindrone POP, which contains 28 hormonally active tablets in each pack. In the US clinical trials of drospirenone 4 mg, scheduled bleeding decreased from 81% in cycle 1 to 20% in cycle 13. Unscheduled spotting and bleeding decreased from 61% to 40% in the same timeframe. Notably, this bleeding pattern was well tolerated; only 0.4% of trial participants discontinued this drospirenone POP due to problems with irregular bleeding or amenorrhea.

In contrast to the continuous norethindrone POP, which is not sufficiently dosed to consistently suppress ovulation, the 4-mg daily dose of drospirenone in this new POP is higher than the 3 mg used in commonly prescribed combination OCs that contain EE and drospirenone. This results in a POP that has more consistent ovulation suppression. Because this drospirenone POP is appropriately dosed and based on a longer-acting progestin, it is more forgiving of inconsistent pill taking. Accordingly, the missed-pill rules for this pill are the same as with combination estrogen-progestin OCs.¹ The package labeling cites a first-year failure rate of 4%, but this includes unconfirmed pregnancies. The Pearl Index from the North American trials, based on confirmed pregnancies in nonbreastfeeding women, was 2.9.²

The package labeling for this drospirenone POP includes few contraindications. Conditions that preclude use include the US Medical Eligibility Criteria for contraception Category 4 condition (breast cancer in the last 5 years), renal impairment, and adrenal insufficiency. Other standard contraindications are listed in the prescribing information. Serum potassium levels should be checked (one time only) in the first cycle only for women who chronically use medications that could cause hyperkalemia, such as nonsteroidal anti-inflammatory drugs.

Given the ovulation suppression associated with this drospirenone POP, the safety of a progestin-only method, and the persistent popularity of OC pills, this pill should greatly increase the use of POPs beyond their traditional niche of postpartum and breastfeeding women. The advent of the drospirenone POP means that clinicians now have better options for women who have contraindications to estrogen and desire to control their own contraceptive use. It would be a logical consideration for over-the-counter accessibility.

2. Transdermal patch with ethinyl estradiol/levonorgestrel

The new EE/levonorgestrel transdermal contraceptive patch (Twirla) is soft and flexible, about the same size as other contraceptive patches, and contains EE 2.3 mg/levonorgestrel 2.6 mg. It provides total estrogen exposure that is similar to that of OCs with EE 30 µg and distinctly lower than estrogen levels seen with the original norelgestromin-containing patch or its 2 subsequent generic versions.³ This EE/levonorgestrel patch uses a new 5-layer drug delivery system that focuses the steroids for absorption beneath the patch; there is no peripheral spread of drug around the patch (FIGURE 1).

Transdermal patches offer the convenience of once-a-week dosing. One patch is used each week for 3 consecutive weeks followed by a patch-free week. Patches can be worn on the abdomen, buttock, or trunk (except breasts). Patches should not be placed consecutively on the same site; after a week’s rest, however, the first site can be reused. All transdermal contraceptive products are indicated for use only by women with a body mass index (BMI) <30 kg/m².⁴

While no head-to-head trials have compared this new lower-dose patch with older patches, each patch was compared against a standardized pill, so meaningful comparisons can be made.

In each case, the circulating estrogen levels associated with use of the EE/levonorgestrel patch were considerably lower than those of the comparator pill, while the older norelgestromin patch consistently delivered higher total estrogen levels than its 35-µg comparator pill (TABLE).³ Along these lines, no VTE events occurred in women in the clinical trial of the new patch among women with a BMI <30 kg/m².⁴

Women with a BMI <25 kg/m² experienced lower Pearl Index (PI) pregnancy rates (3.5%) compared with women with a BMI between 25 and 30 kg/m² (5.7%), according to clinical trial data cited in the package labeling. All the modern PI criteria were used to calculate these failure rates. Cycles in which no coitus occurred were excluded. Similarly, cycles in which another contraceptive method (for example, condoms) was added (even once) were excluded. Frequent pregnancy testing was done in the study centers and by the women at home. Bleeding patterns were well accepted; only 2.2% of study participants exited the study early due to menstrual disorders of any kind. Similarly, 3.1% of women discontinued use because of application site disorders. Women should be advised to press down on the patch edges after emerging from water exposure. Replacement patches are rapidly available from the manufacturer should permanent complete patch detachment occur.

Larger-scale phase 4 trials will be conducted to study the impact of this lower-dose patch on VTE rates.

Continue to: 3. A 1-year contraceptive vaginal ring...

The need to obtain new supplies every month or every 3 months contributes to high rates of contraceptive failure and unintended pregnancy among women using short-acting hormonal contraceptives (pills, patches, and vaginal rings).⁵ A woman-controlled contraceptive that would provide 1 year of protection against unintended pregnancy represents a step forward. A contraceptive vaginal ring (CVR) that releases the novel progestin segesterone acetate and EE provides woman-controlled contraception for up to 1 year. This CVR (Annovera) received FDA approval in 2018 and has been marketed in the United States since 2020.

The segesterone acetate/EE CVR is a soft, flexible ring that is opaque white in color and fabricated from nonbiodegradable silicone (FIGURE 2). The outside diameter is 5.6 cm, compared with the 5.4-cm outer diameter of the etonogestrel/EE vaginal ring (NuvaRing). The segesterone acetate/EE CVR has 2 channels: one releases segesterone acetate only and the other releases segesterone acetate and EE. In contrast with the etonogestrel/EE CVR, the segesterone acetate/EE CVR does not need to be refrigerated when stored.⁶

4. An OC with a novel estrogen

Even as use of intrauterine devices and contraceptive implants continues to grow, OCs remain the reversible contraceptive most used by US women. While OCs have been widely studied and represent a safe method of contraception for most reproductive-age women, combination estrogen-progestin OCs are well recognized to increase the risk of VTE. Although the primary role of the progestin component of combination OCs is to suppress ovulation, estrogen is included in combination OCs to stimulate endometrial proliferation, thereby causing predictable bleeding. EE, the potent synthetic estrogen used in the great majority of current OC formulations, induces hepatic production of prothrombotic proteins while inhibiting synthesis of antithrombotic proteins. While the lower EE doses (10–35 µg) in today’s OC formulations are associated with a lower VTE risk than older OCs that contained higher doses of estrogen, VTE continues to represent the principal health risk associated with use of combination OCs. Accordingly, development of a combination OC that has less impact on risk of VTE would be appealing.

In April 2021, the FDA approved an OC formulation that combines 15 mg of the novel estrogen estetrol with 3 mg of drospirenone (Nextstellis). This dose of drospirenone is the same as that used in commonly prescribed EE/drospirenone OC formulations. Also known as E4, estetrol is a natural estrogen synthesized by the fetal liver. Plant-derived E4 is used in this new OC.

Depending on the tissue, E4 acts differently than other estrogens. Similar to other estrogens, E4 acts as an agonist on the nuclear receptor to produce beneficial effects in bone, vaginal mucosa, and heart.⁸ Unlike other estrogens, E4 inhibits proliferation of mammary gland cells and has a neutral impact on the liver.⁹

In contrast with EE, E4 is not inhibited by the liver’s P450 enzymes; accordingly, the risk of drug-drug interactions is reduced. Because E4 is primarily excreted through the urine and not through the biliary tract, the risk of gallstone formation may be lower than with an EE OC. Likewise, E4 has substantially less impact on triglycerides, which are increased with EE. Finally, because of E4’s reduced effect on the liver, the impact on clotting parameters is less than that observed with an OC formulated with EE.¹⁰ This latter observation raises the possibility that VTE risk is lower with the E4/drospirenone OC than an OC formulated with EE.

A 13-cycle phase 3 trial of the E4/drospirenone OC conducted in the United States and Canada enrolled 1,864 women aged 16 to 50 years, including 1,674 who were aged 16 to 35 years.¹¹ Among women in this latter age group, the PI was 2.65 per 100 woman-years. Bleeding/cycle control patterns were similar to those observed in recent trials of other combination contraceptives. Likewise, the proportion of trial participants who discontinued the study due to adverse effects was similar to or lower than that noted in recent trials of other combination contraceptives. Of particular note, no cases of VTE were noted among trial participants of any BMI, a finding which contrasts with recent phase 3 trials of other combination contraceptives. The result of this pivotal trial suggests that the theoretic advantages of E4 when used in a combination OC formulation may translate into a safer, effective, and well-tolerated contraceptive.

Refinements in hormonal contraceptives continue

The 4 new short-acting hormonal contraceptives we reviewed represent enhancements on existing pills, patches, and rings. We hope that, financially, women will have access to these innovative methods and, in particular, that third-party payers will facilitate women’s access to these enhanced short-acting hormonal contraceptives. ●

Uterine fibroids are a common condition that affects up to 80% of reproductive-age women.¹ Many women with fibroids are asymptomatic, but some experience symptoms that profoundly disrupt their lives, such as abnormal uterine bleeding, pelvic pain, and bulk symptoms including bladder and bowel dysfunction.² Although hysterectomy remains the definitive treatment for symptomatic fibroids, many women seek more conservative management. Hormonal treatment, such as contraceptive pills, levonorgestrel intrauterine devices, and gonadotropin-releasing hormone analogs, can improve heavy menstrual bleeding and anemia.³ Additionally, uterine artery embolization is a nonsurgical uterine-sparing option. However, these treatments are not ideal options for women who want to conceive.⁴ For reproductive-age women who desire future fertility, myomectomy has been the standard of care. Unfortunately, by the time patients become symptomatic from their fibroids and seek care, they may have numerous and/or sizable fibroids that result in high blood loss, surgical scarring, and the probable need for cesarean delivery (FIGURES 1 and 2).⁵

For patients who desire future conception, treatment of uterine fibroids poses a challenge in which optimizing symptomatic improvement must be balanced with protecting fertility and improving reproductive outcomes. In recent years, high-intensity focused ultrasound (FUS) and radiofrequency ablation (RFA) have been presented as less invasive, uterine-sparing alternatives for fibroid treatment that could potentially provide that balance.

In this article, we briefly review the available uterine-sparing fibroid treatments and their outcomes and then focus specifically on RFA as a possible option to address the fibroid treatment gap for reproductive-age women who desire future fertility.

Overview of uterine-sparing treatments

Two approaches can be pursued for conservative fibroid treatment: fibroid removal and fibroid necrosis (TABLE 1). We focus this review on outcomes for the most widely available of these treatments.

Myomectomy

For reproductive-age women who wish to conceive, surgical removal of fibroids has been the standard of care for symptomatic patients. Myomectomy can be performed via laparotomy, laparoscopy, robot-assisted surgery, and hysteroscopy. The mode of surgery depends on the fibroid characteristics (size, number, and location) and the surgeon’s skill set. Although some variation in the data exists, overall surgical outcomes, including blood loss, postoperative pain, and length of stay, are generally more favorable for minimally invasive approaches compared with laparotomy, with no significant differences in fibroid recurrence or reproductive outcomes (live birth rate, miscarriage rate, and cesarean delivery rate).⁶ This comes at the expense of longer operating time compared with laparotomy.⁷

While improvement in abnormal uterine bleeding and pelvic pain is reliable and usually significant after myomectomy,⁸ reproductive implications also warrant consideration. Myomectomy is associated with subsequent uterine adhesion formation, with some studies finding rates up to 83% to 94% depending on the surgical approach and the number of fibroids removed.⁹ These adhesions can impair fertility success.¹⁰ Myomectomy also is associated with high rates of cesarean delivery,⁵ invasive placentation (including placenta accreta spectrum),¹¹ and uterine rupture.¹² While the latter 2 complications are rare, they potentially can be catastrophic and should be kept in mind.

Continue to: Uterine artery embolization...

Uterine artery embolization

As a nonsurgical alternative to myomectomy, uterine artery embolization (UAE) has gained popularity as a conservative fibroid treatment since it was introduced in 1995. It is less invasive than myomectomy, a benefit for patients who decline surgery or are not ideal candidates for surgery.¹³ Evidence suggests that UAE produces overall comparable symptomatic improvement compared with myomectomy. One study showed no significant differences between UAE and myomectomy in terms of decreased uterine volume and menstrual bleeding at 6-month follow-up.¹⁴ In terms of long-term outcomes, a large multicenter study showed no significant difference in reintervention rates at 7 years posttreatment between UAE and myomectomy (8.9% vs 11.2%, respectively), and a significantly higher rate of improved menstrual bleeding with UAE (79.4% vs 49.5%), with no significant difference in bulk symptoms.¹⁵ The evidence is not entirely consistent, as other studies have shown increased rates of reintervention with UAE,^8,16 but overall UAE can be considered a reasonable alternative to myomectomy in terms of symptomatic improvement.

Pregnancy outcomes data, however, are mixed, and UAE often is not recommended for patients with future fertility plans. In a large review article that compared minimally invasive fibroid treatments, UAE was associated with a lower live birth rate compared with myomectomy and ablation techniques (60.6% for UAE, 75.6% for myomectomy, and 70.5% for ablation), and it also had the highest rate of miscarriage (27.4% for UAE vs 19.0% for myomectomy and 11.9% for ablation) and abnormal placentation.¹² While UAE remains an effective option for conservative treatment of symptomatic fibroids, it appears to have a worse impact on reproductive outcomes compared with myomectomy or ablative treatments.

Magnetic resonance–guided focused ultrasound

Emerging as a noninvasive ablation treatment for fibroids, magnetic resonance–guided focused ultrasound (MRgFUS) uses targeted high-intensity ultrasound pulses to cause thermal and mechanical fibroid tissue disruption.¹⁷ Data on this treatment are less robust given that it is newer than myomectomy or UAE. One study showed a decrease in fibroid volume by 12% at 1 month and 15% at 6 months, with 37.1% of patients reporting marked improvement in symptoms and an additional 31.4% reporting partial improvement; these are modest numbers compared with other treatment approaches.¹⁸ Another study showed more favorable outcomes, with 74% of patients reporting clinically significant improvement in bleeding and pain, and a 12.7% reintervention rate, comparable to rates reported for UAE and myomectomy.¹⁹

Because MRgFUS is newer than UAE or myomectomy, data are limited in terms of pregnancy outcomes, particularly because initial trials excluded women with future fertility plans due to lack of knowledge regarding pregnancy safety. A follow-up case series from one of the initial studies showed a decreased miscarriage rate compared with UAE, a term delivery rate of 93%, and a similar rate of abnormal placentation.²⁰ A more recent systematic review concluded that reproductive outcomes were noninferior to myomectomy; however, the outcomes data for MRgFUS were heterogenous and many studies did not report pregnancy rates.²¹

Overall, MRgFUS appears to be an effective alternative approach for symptomatic fibroids, but the long-term data are not yet conclusive and information on pregnancy safety and outcomes largely is lacking. Recent reviews have not made definitive statements on whether MRgFUS should be offered to patients desiring future fertility.

RFA is a promising option

RFA is another noninvasive fibroid ablation technique that has become more widely adopted in recent years. Here, we describe the basics of RFA and its impact on fibroid symptoms and reproductive outcomes.

The RFA technique

RFA uses hyperthermic energy from a handpiece and real-time ultrasound for targeted coagulative necrosis via a laparoscopic (L-RFA) or transcervical (TC-RFA) approach.²² A comparison between the 2 devices available on the market in the United States is shown in TABLE 2. Ultrasound guidance allows placement of radiofrequency needles directly into the fibroid to target local treatment to the fibroid tissue only. Once the fibroid undergoes coagulative necrosis, the process of fibroid resorption and volume reduction occurs over weeks to months, depending on the fibroid size.

Impact on fibroid symptoms

Both laparoscopic and transcervical RFA approaches have shown significant decreases in pelvic pain and heavy menstrual bleeding associated with fibroids and a low reintervention rate that emphasizes the durability of their impact.

A feasibility and safety study of a TC-RFA device prior to the primary clinical trials found only a 4.3% reintervention rate in the first 18 months postprocedure.²³ The pivotal clinical trial of a TC-RFA device that followed also reported a low 5.5% reintervention rate in the first 24 months postprocedure, with significant improvement in health-related quality-of-life and high patient satisfaction²⁴ (results shown in TABLE 2, along with trial results for an L-RFA device). A subsequent study of TC-RFA reported that symptomatic improvement persisted at 3-year follow-up, with a 9.2% reintervention rate comparable to existing fibroid treatments such as myomectomy and UAE.²⁵ The original L-RFA trial also has shown similar positive results at 2-year follow-up, with a low reintervention rate of 4.8% after treatment, and similar patient satisfaction and quality-of-life improvements as TC-RFA.²⁶ While long-term data are limited by only recent approval by the Food and Drug Administration (FDA) of a TC-RFA device in 2018, one study followed clinical trial patients for a mean duration of 64 months. This study found no surgical reinterventions in the first 3.5 years posttreatment and a persistent reduction in fibroid symptoms from baseline 64.9 points to 27.6 points, as assessed by a validated symptom severity scale (out of 100 points).²⁷ Similar improvements in health-related quality-of life-were also found to persist for years posttreatment.⁴

In a large systematic review that compared L-RFA, MRgFUS, UAE, and myomectomy, L-RFA had similar improvement rates in quality-of-life and symptom severity scores compared with myomectomy, with no significant difference in reintervention rates.²⁸ This review also noted minimal heterogeneity among RFA meta-analyses data in contrast to significant heterogeneity among UAE and myomectomy data.

Reproductive outcomes

Similar to MRgFUS, the initial studies of RFA devices largely excluded women with future fertility plans, as data on safety were lacking. However, many RFA devices are now on the market across the globe, and subsequent pregnancies have been tracked and reported.

A large case series that included clinical trials and commercial settings reported a miscarriage rate (13.3%) similar to that of the general obstetric population and no cases of uterine rupture, invasive placentation, preterm delivery, or placental abruption.²⁹ Other case series have reported live birth rates similar those with myomectomy, and safe and favorable pregnancy outcomes with RFA have been supported by larger systematic reviews of all ablation techniques.¹²

Continue to: Uterine impact...

Uterine impact

One study of TC-RFA patients showed a greater than 65% reduction in fibroid volume (with a 90% reduction in fibroid volume for fibroids larger than 6 cm prior to RFA), and 54% of patients reported complete resolution of symptoms, with another 36% reporting decreased symptoms.³⁰ Similar decreases in fibroid volume, ranging from 65% to 84%, have been reported in numerous follow-up studies, with significant decreases in bleeding and pain in 78% to 88% of patients.^23,31-33 Additionally, a large secondary analysis of a TC-RFA clinical trial showed that patients did not have any significant decrease in uterine wall thickness or integrity on follow-up with magnetic resonance imaging compared with baseline measurements, and they did not have any new myometrial scars (assessed as nonperfused linear areas).²²

As with other ablation techniques, most data on RFA pregnancy outcomes come from case series, and further research and evaluation are needed. Existing studies, however, have demonstrated promising aspects of RFA that argue its usefulness in women with fertility plans.

A prospective trial that evaluated intrauterine adhesion formation with use of a TC-RFA device found no new adhesions on 6-week follow-up hysteroscopy compared with baseline pre-RFA hysteroscopy.³⁴ Because intrauterine adhesion formation and uterine rupture are both significant concerns with other uterine-sparing fibroid treatment approaches such as myomectomy, these findings suggest that RFA may be a better alternative for women who are planning future pregnancies, as they may have increased fertility success and decreased catastrophic complications.

The consensus is growing that RFA is a safe and effective option for women who desire minimally invasive fibroid treatment and want to preserve fertility.

Unique benefits of RFA

In this article, we highlight RFA as an emerging treatment option for fibroid management, particularly for women who desire a uterine-sparing approach to preserve their reproductive options. Although myomectomy has been the standard of care for many years, with UAE as the alternative nonsurgical treatment, neither approach provides the best balance between symptomatic improvement and reproductive outcomes, and neither is without pregnancy risks. In addition, many women with symptomatic fibroids do not desire future conception but decline fibroid removal for religious or personal reasons. RFA offers these women an alternative minimally invasive option for uterine-sparing fibroid treatment.

RFA presents a unique “incision-free” fibroid treatment that is truly minimally invasive. This technique minimizes the risks associated with myomectomy, such as intra-abdominal adhesions, intrauterine adhesions (Asherman syndrome), need for cesarean delivery, and pregnancy complications such as uterine rupture or invasive placentation. Furthermore, the evolution of an RFA transcervical approach has enabled treatment with no abdominal or uterine incisions, thus offering all the above reproductive benefits as well as the operative benefits of a faster recovery, less pain, and less risk of intraperitoneal surgical complications.

While many women desire uterine-sparing fibroid treatment even without future fertility plans, the larger question is whether we should treat fibroids more strategically for women who desire future fertility. Myomectomy and UAE are effective and reliable in terms of fibroid symptomatic improvement, but RFA promises more beneficial reproductive outcomes. The ability to avoid uterine myometrial incisions and still attain significant symptomatic improvement should be prioritized in these patients.

Currently, RFA is not approved by the FDA as a fertility-enabling treatment, and these patients have been largely excluded from RFA studies. However, the reproductive-age patient who desires future conception may benefit most from RFA. Furthermore, RFA technology also could address the gap in uterine-sparing treatment for reproductive-age women with adenomyosis. Although a complete review of adenomyosis treatment is beyond the scope of this article, recent studies show that RFA produces similar improvement in both uterine volume and symptom severity in women with adenomyosis.^35-37 ●

Uterine fibroids are a common condition that affects up to 80% of reproductive-age women.¹ Many women with fibroids are asymptomatic, but some experience symptoms that profoundly disrupt their lives, such as abnormal uterine bleeding, pelvic pain, and bulk symptoms including bladder and bowel dysfunction.² Although hysterectomy remains the definitive treatment for symptomatic fibroids, many women seek more conservative management. Hormonal treatment, such as contraceptive pills, levonorgestrel intrauterine devices, and gonadotropin-releasing hormone analogs, can improve heavy menstrual bleeding and anemia.³ Additionally, uterine artery embolization is a nonsurgical uterine-sparing option. However, these treatments are not ideal options for women who want to conceive.⁴ For reproductive-age women who desire future fertility, myomectomy has been the standard of care. Unfortunately, by the time patients become symptomatic from their fibroids and seek care, they may have numerous and/or sizable fibroids that result in high blood loss, surgical scarring, and the probable need for cesarean delivery (FIGURES 1 and 2).⁵

For patients who desire future conception, treatment of uterine fibroids poses a challenge in which optimizing symptomatic improvement must be balanced with protecting fertility and improving reproductive outcomes. In recent years, high-intensity focused ultrasound (FUS) and radiofrequency ablation (RFA) have been presented as less invasive, uterine-sparing alternatives for fibroid treatment that could potentially provide that balance.

This study found no surgical reinterventions in the first 3.5 years posttreatment and a persistent reduction in fibroid symptoms from baseline 64.9 points to 27.6 points, as assessed by a validated symptom severity scale (out of 100 points).²⁷ Similar improvements in health-related quality-of life-were also found to persist for years posttreatment.⁴

In a large systematic review that compared L-RFA, MRgFUS, UAE, and myomectomy, L-RFA had similar improvement rates in quality-of-life and symptom severity scores compared with myomectomy, with no significant difference in reintervention rates.²⁸ This review also noted minimal heterogeneity among RFA meta-analyses data in contrast to significant heterogeneity among UAE and myomectomy data.

Reproductive outcomes

Similar to MRgFUS, the initial studies of RFA devices largely excluded women with future fertility plans, as data on safety were lacking. However, many RFA devices are now on the market across the globe, and subsequent pregnancies have been tracked and reported.

A large case series that included clinical trials and commercial settings reported a miscarriage rate (13.3%) similar to that of the general obstetric population and no cases of uterine rupture, invasive placentation, preterm delivery, or placental abruption.²⁹ Other case series have reported live birth rates similar those with myomectomy, and safe and favorable pregnancy outcomes with RFA have been supported by larger systematic reviews of all ablation techniques.¹²

Uterine impact

One study of TC-RFA patients showed a greater than 65% reduction in fibroid volume (with a 90% reduction in fibroid volume for fibroids larger than 6 cm prior to RFA), and 54% of patients reported complete resolution of symptoms, with another 36% reporting decreased symptoms.³⁰ Similar decreases in fibroid volume, ranging from 65% to 84%, have been reported in numerous follow-up studies, with significant decreases in bleeding and pain in 78% to 88% of patients.^23,31-33 Additionally, a large secondary analysis of a TC-RFA clinical trial showed that patients did not have any significant decrease in uterine wall thickness or integrity on follow-up with magnetic resonance imaging compared with baseline measurements, and they did not have any new myometrial scars (assessed as nonperfused linear areas).²²

As with other ablation techniques, most data on RFA pregnancy outcomes come from case series, and further research and evaluation are needed. Existing studies, however, have demonstrated promising aspects of RFA that argue its usefulness in women with fertility plans.

A prospective trial that evaluated intrauterine adhesion formation with use of a TC-RFA device found no new adhesions on 6-week follow-up hysteroscopy compared with baseline pre-RFA hysteroscopy.³⁴ Because intrauterine adhesion formation and uterine rupture are both significant concerns with other uterine-sparing fibroid treatment approaches such as myomectomy, these findings suggest that RFA may be a better alternative for women who are planning future pregnancies, as they may have increased fertility success and decreased catastrophic complications.

The consensus is growing that RFA is a safe and effective option for women who desire minimally invasive fibroid treatment and want to preserve fertility.

Unique benefits of RFA

In this article, we highlight RFA as an emerging treatment option for fibroid management, particularly for women who desire a uterine-sparing approach to preserve their reproductive options. Although myomectomy has been the standard of care for many years, with UAE as the alternative nonsurgical treatment, neither approach provides the best balance between symptomatic improvement and reproductive outcomes, and neither is without pregnancy risks. In addition, many women with symptomatic fibroids do not desire future conception but decline fibroid removal for religious or personal reasons. RFA offers these women an alternative minimally invasive option for uterine-sparing fibroid treatment.

RFA presents a unique “incision-free” fibroid treatment that is truly minimally invasive. This technique minimizes the risks associated with myomectomy, such as intra-abdominal adhesions, intrauterine adhesions (Asherman syndrome), need for cesarean delivery, and pregnancy complications such as uterine rupture or invasive placentation. Furthermore, the evolution of an RFA transcervical approach has enabled treatment with no abdominal or uterine incisions, thus offering all the above reproductive benefits as well as the operative benefits of a faster recovery, less pain, and less risk of intraperitoneal surgical complications.

While many women desire uterine-sparing fibroid treatment even without future fertility plans, the larger question is whether we should treat fibroids more strategically for women who desire future fertility. Myomectomy and UAE are effective and reliable in terms of fibroid symptomatic improvement, but RFA promises more beneficial reproductive outcomes. The ability to avoid uterine myometrial incisions and still attain significant symptomatic improvement should be prioritized in these patients.

Currently, RFA is not approved by the FDA as a fertility-enabling treatment, and these patients have been largely excluded from RFA studies. However, the reproductive-age patient who desires future conception may benefit most from RFA. Furthermore, RFA technology also could address the gap in uterine-sparing treatment for reproductive-age women with adenomyosis. Although a complete review of adenomyosis treatment is beyond the scope of this article, recent studies show that RFA produces similar improvement in both uterine volume and symptom severity in women with adenomyosis.^35-37 ●

Uterine fibroids are a common condition that affects up to 80% of reproductive-age women.¹ Many women with fibroids are asymptomatic, but some experience symptoms that profoundly disrupt their lives, such as abnormal uterine bleeding, pelvic pain, and bulk symptoms including bladder and bowel dysfunction.² Although hysterectomy remains the definitive treatment for symptomatic fibroids, many women seek more conservative management. Hormonal treatment, such as contraceptive pills, levonorgestrel intrauterine devices, and gonadotropin-releasing hormone analogs, can improve heavy menstrual bleeding and anemia.³ Additionally, uterine artery embolization is a nonsurgical uterine-sparing option. However, these treatments are not ideal options for women who want to conceive.⁴ For reproductive-age women who desire future fertility, myomectomy has been the standard of care. Unfortunately, by the time patients become symptomatic from their fibroids and seek care, they may have numerous and/or sizable fibroids that result in high blood loss, surgical scarring, and the probable need for cesarean delivery (FIGURES 1 and 2).⁵

For patients who desire future conception, treatment of uterine fibroids poses a challenge in which optimizing symptomatic improvement must be balanced with protecting fertility and improving reproductive outcomes. In recent years, high-intensity focused ultrasound (FUS) and radiofrequency ablation (RFA) have been presented as less invasive, uterine-sparing alternatives for fibroid treatment that could potentially provide that balance.

In this article, we briefly review the available uterine-sparing fibroid treatments and their outcomes and then focus specifically on RFA as a possible option to address the fibroid treatment gap for reproductive-age women who desire future fertility.

Overview of uterine-sparing treatments

Two approaches can be pursued for conservative fibroid treatment: fibroid removal and fibroid necrosis (TABLE 1). We focus this review on outcomes for the most widely available of these treatments.

Myomectomy

For reproductive-age women who wish to conceive, surgical removal of fibroids has been the standard of care for symptomatic patients. Myomectomy can be performed via laparotomy, laparoscopy, robot-assisted surgery, and hysteroscopy. The mode of surgery depends on the fibroid characteristics (size, number, and location) and the surgeon’s skill set. Although some variation in the data exists, overall surgical outcomes, including blood loss, postoperative pain, and length of stay, are generally more favorable for minimally invasive approaches compared with laparotomy, with no significant differences in fibroid recurrence or reproductive outcomes (live birth rate, miscarriage rate, and cesarean delivery rate).⁶ This comes at the expense of longer operating time compared with laparotomy.⁷

While improvement in abnormal uterine bleeding and pelvic pain is reliable and usually significant after myomectomy,⁸ reproductive implications also warrant consideration. Myomectomy is associated with subsequent uterine adhesion formation, with some studies finding rates up to 83% to 94% depending on the surgical approach and the number of fibroids removed.⁹ These adhesions can impair fertility success.¹⁰ Myomectomy also is associated with high rates of cesarean delivery,⁵ invasive placentation (including placenta accreta spectrum),¹¹ and uterine rupture.¹² While the latter 2 complications are rare, they potentially can be catastrophic and should be kept in mind.

Uterine artery embolization

As a nonsurgical alternative to myomectomy, uterine artery embolization (UAE) has gained popularity as a conservative fibroid treatment since it was introduced in 1995. It is less invasive than myomectomy, a benefit for patients who decline surgery or are not ideal candidates for surgery.¹³ Evidence suggests that UAE produces overall comparable symptomatic improvement compared with myomectomy. One study showed no significant differences between UAE and myomectomy in terms of decreased uterine volume and menstrual bleeding at 6-month follow-up.¹⁴ In terms of long-term outcomes, a large multicenter study showed no significant difference in reintervention rates at 7 years posttreatment between UAE and myomectomy (8.9% vs 11.2%, respectively), and a significantly higher rate of improved menstrual bleeding with UAE (79.4% vs 49.5%), with no significant difference in bulk symptoms.¹⁵ The evidence is not entirely consistent, as other studies have shown increased rates of reintervention with UAE,^8,16 but overall UAE can be considered a reasonable alternative to myomectomy in terms of symptomatic improvement.

Pregnancy outcomes data, however, are mixed, and UAE often is not recommended for patients with future fertility plans. In a large review article that compared minimally invasive fibroid treatments, UAE was associated with a lower live birth rate compared with myomectomy and ablation techniques (60.6% for UAE, 75.6% for myomectomy, and 70.5% for ablation), and it also had the highest rate of miscarriage (27.4% for UAE vs 19.0% for myomectomy and 11.9% for ablation) and abnormal placentation.¹² While UAE remains an effective option for conservative treatment of symptomatic fibroids, it appears to have a worse impact on reproductive outcomes compared with myomectomy or ablative treatments.

Magnetic resonance–guided focused ultrasound

Emerging as a noninvasive ablation treatment for fibroids, magnetic resonance–guided focused ultrasound (MRgFUS) uses targeted high-intensity ultrasound pulses to cause thermal and mechanical fibroid tissue disruption.¹⁷ Data on this treatment are less robust given that it is newer than myomectomy or UAE. One study showed a decrease in fibroid volume by 12% at 1 month and 15% at 6 months, with 37.1% of patients reporting marked improvement in symptoms and an additional 31.4% reporting partial improvement; these are modest numbers compared with other treatment approaches.¹⁸ Another study showed more favorable outcomes, with 74% of patients reporting clinically significant improvement in bleeding and pain, and a 12.7% reintervention rate, comparable to rates reported for UAE and myomectomy.¹⁹

Because MRgFUS is newer than UAE or myomectomy, data are limited in terms of pregnancy outcomes, particularly because initial trials excluded women with future fertility plans due to lack of knowledge regarding pregnancy safety. A follow-up case series from one of the initial studies showed a decreased miscarriage rate compared with UAE, a term delivery rate of 93%, and a similar rate of abnormal placentation.²⁰ A more recent systematic review concluded that reproductive outcomes were noninferior to myomectomy; however, the outcomes data for MRgFUS were heterogenous and many studies did not report pregnancy rates.²¹

Overall, MRgFUS appears to be an effective alternative approach for symptomatic fibroids, but the long-term data are not yet conclusive and information on pregnancy safety and outcomes largely is lacking. Recent reviews have not made definitive statements on whether MRgFUS should be offered to patients desiring future fertility.

RFA is a promising option

RFA is another noninvasive fibroid ablation technique that has become more widely adopted in recent years. Here, we describe the basics of RFA and its impact on fibroid symptoms and reproductive outcomes.

The RFA technique

RFA uses hyperthermic energy from a handpiece and real-time ultrasound for targeted coagulative necrosis via a laparoscopic (L-RFA) or transcervical (TC-RFA) approach.²² A comparison between the 2 devices available on the market in the United States is shown in TABLE 2. Ultrasound guidance allows placement of radiofrequency needles directly into the fibroid to target local treatment to the fibroid tissue only. Once the fibroid undergoes coagulative necrosis, the process of fibroid resorption and volume reduction occurs over weeks to months, depending on the fibroid size.

Impact on fibroid symptoms

Both laparoscopic and transcervical RFA approaches have shown significant decreases in pelvic pain and heavy menstrual bleeding associated with fibroids and a low reintervention rate that emphasizes the durability of their impact.

A feasibility and safety study of a TC-RFA device prior to the primary clinical trials found only a 4.3% reintervention rate in the first 18 months postprocedure.²³ The pivotal clinical trial of a TC-RFA device that followed also reported a low 5.5% reintervention rate in the first 24 months postprocedure, with significant improvement in health-related quality-of-life and high patient satisfaction²⁴ (results shown in TABLE 2, along with trial results for an L-RFA device). A subsequent study of TC-RFA reported that symptomatic improvement persisted at 3-year follow-up, with a 9.2% reintervention rate comparable to existing fibroid treatments such as myomectomy and UAE.²⁵ The original L-RFA trial also has shown similar positive results at 2-year follow-up, with a low reintervention rate of 4.8% after treatment, and similar patient satisfaction and quality-of-life improvements as TC-RFA.²⁶ While long-term data are limited by only recent approval by the Food and Drug Administration (FDA) of a TC-RFA device in 2018, one study followed clinical trial patients for a mean duration of 64 months. This study found no surgical reinterventions in the first 3.5 years posttreatment and a persistent reduction in fibroid symptoms from baseline 64.9 points to 27.6 points, as assessed by a validated symptom severity scale (out of 100 points).²⁷ Similar improvements in health-related quality-of life-were also found to persist for years posttreatment.⁴

In a large systematic review that compared L-RFA, MRgFUS, UAE, and myomectomy, L-RFA had similar improvement rates in quality-of-life and symptom severity scores compared with myomectomy, with no significant difference in reintervention rates.²⁸ This review also noted minimal heterogeneity among RFA meta-analyses data in contrast to significant heterogeneity among UAE and myomectomy data.

C. Overall, tomosynthesis depicts an additional 1 to 2 cancers per thousand women screened in the first round of screening when added to standard digital mammography;^1-3 however, this improvement in cancer detection is only observed in women with fatty breasts (category A), scattered fibroglandular tissue (category B), and heterogeneously dense breasts (category C). Importantly, tomosynthesis does not significantly improve breast cancer detection in women with extremely dense breasts (category D).^2,4

Digital breast tomosynthesis, also referred to as “3-dimensional mammography” (3D mammography) or tomosynthesis, uses a dedicated electronic detector system to obtain multiple projection images that are reconstructed by the computer to create thin slices or slabs of multiple slices of the breast. These slices can be individually “scrolled through” by the radiologist to reduce tissue overlap that may obscure breast cancers on a standard mammogram. While tomosynthesis improves breast cancer detection in women with fatty, scattered fibroglandular density, and heterogeneously dense breasts, there is very little soft tissue contrast in extremely dense breasts due to insufficient fat, and some cancers will remain hidden by dense tissue even on sliced images through the breast.

FIGURE 2 shows an example of cancer that was missed on tomosynthesis in a 51-year-old woman with extremely dense breasts and right breast pain. The cancer was masked by extremely dense tissue on standard digital mammography and tomosynthesis; no abnormalities were detected. Ultrasonography showed a 1.6-cm, irregular, hypoechoic mass at the site of pain, and biopsy revealed a grade 3 triple-receptor negative invasive ductal carcinoma.

No, Mr. Bond, I expect you to die

Movie watching usually requires a certain suspension of disbelief, and it’s safe to say James Bond movies require this more than most. Between the impossible gadgets and ludicrous doomsday plans, very few have ever stopped to consider the health risks of the James Bond universe.

Tumisu/Pixabay

Now, however, Bond, James Bond, has met his most formidable opponent: Wouter Graumans, a graduate student in epidemiology from the Netherlands. During a foray to Burkina Faso to study infectious diseases, Mr. Graumans came down with a case of food poisoning, which led him to wonder how 007 is able to trot across this big world of ours without contracting so much as a sinus infection.

Because Mr. Graumans is a man of science and conviction, mere speculation wasn’t enough. He and a group of coauthors wrote an entire paper on the health risks of the James Bond universe.

Doing so required watching over 3,000 minutes of numerous movies and analyzing Bond’s 86 total trips to 46 different countries based on current Centers for Disease Control and Prevention advice for travel to those countries. Time which, the authors state in the abstract, “could easily have been spent on more pressing societal issues or forms of relaxation that are more acceptable in academic circles.”

Naturally, Mr. Bond’s line of work entails exposure to unpleasant things, such as poison, dehydration, heatstroke, and dangerous wildlife (everything from ticks to crocodiles), though oddly enough he never succumbs to any of it. He’s also curiously immune to hangovers, despite rarely drinking anything nonalcoholic. There are also less obvious risks: For one, 007 rarely washes his hands. During one movie, he handles raw chicken to lure away a pack of crocodiles but fails to wash his hands afterward, leaving him at risk for multiple food-borne illnesses.

Of course, we must address the elephant in the bedroom: Mr. Bond’s numerous, er, encounters with women. One would imagine the biggest risk to those women would be from the various STDs that likely course through Bond’s body, but of the 27% who died shortly after … encountering … him, all involved violence, with disease playing no obvious role. Who knows, maybe he’s clean? Stranger things have happened.

The timing of this article may seem a bit suspicious. Was it a PR stunt by the studio? Rest assured, the authors addressed this, noting that they received no funding for the study, and that, “given the futility of its academic value, this is deemed entirely appropriate by all authors.” We love when a punchline writes itself.
 

How to see Atlanta on $688.35 a day

The world is always changing, so we have to change with it. This week, LOTME becomes a travel guide, and our first stop is the Big A, the Big Peach, Dogwood City, Empire City of the South, Wakanda.

There’s lots to do in Atlanta: Celebrate a World Series win, visit the College Football Hall of Fame or the World of Coca Cola, or take the Stranger Things/Upside Down film locations tour. Serious adventurers, however, get out of the city and go to Emory Decatur Hospital in – you guessed it – Decatur (unofficial motto: “Everything is Greater in Decatur”).

Find the emergency room and ask for Taylor Davis, who will be your personal guide. She’ll show you how to check in at the desk, sit in the waiting room for 7 hours, and then leave without seeing any medical personnel or receiving any sort of attention whatsoever. All the things she did when she went there in July for a head injury.

Ms. Davis told Fox5 Atlanta: “I didn’t get my vitals taken, nobody called my name. I wasn’t seen at all.”

But wait! There’s more! By booking your trip through LOTMEgo* and using the code “Decatur,” you’ll get the Taylor Davis special, which includes a bill/cover charge for $688.35 from the hospital. An Emory Healthcare patient financial services employee told Ms. Davis that “you get charged before you are seen. Not for being seen.”

If all this has you ready to hop in your car (really?), then check out LOTMEgo* on Twittbook and InstaTok. You’ll also find trick-or-treating tips and discounts on haunted hospital tours.

Breaking down the hot flash

Do you ever wonder why we scramble for cold things when we’re feeling nauseous? Whether it’s the cool air that needs to hit your face in the car or a cold, damp towel on the back of your neck, scientists think it could possibly be an evolutionary mechanism at the cellular level.

Piqsels

Motion sickness it’s actually a battle of body temperature, according to an article from LiveScience. Capillaries in the skin dilate, allowing for more blood flow near the skin’s surface and causing core temperature to fall. Once body temperature drops, the hypothalamus, which regulates temperature, tries to do its job by raising body temperature. Thus the hot flash!

The cold compress and cool air help fight the battle by counteracting the hypothalamus, but why the drop in body temperature to begin with?

There are a few theories. Dr. Robert Glatter, an emergency physician at Lenox Hill Hospital in New York, told LiveScience that the lack of oxygen needed in body tissue to survive at lower temperatures could be making it difficult to get oxygen to the body when a person is ill, and is “more likely an adaptive response influenced by poorly understood mechanisms at the cellular level.”

Another theory is that the nausea and body temperature shift is the body’s natural response to help people vomit.

Then there’s the theory of “defensive hypothermia,” which suggests that cold sweats are a possible mechanism to conserve energy so the body can fight off an intruder, which was supported by a 2014 study and a 2016 review.

It’s another one of the body’s many survival tricks.
 

Teachers were right: Pupils can do the math

Teachers liked to preach that we wouldn’t have calculators with us all the time, but that wound up not being true. Our phones have calculators at the press of a button. But maybe even calculators aren’t always needed because our pupils do more math than you think.

pxfuel

The pupil light reflex – constrict in light and dilate in darkness – is well known, but recent work shows that pupil size is also regulated by cognitive and perceptual factors. By presenting subjects with images of various numbers of dots and measuring pupil size, the investigators were able to show “that numerical information is intrinsically related to perception,” lead author Dr. Elisa Castaldi of Florence University noted in a written statement.

The researchers found that pupils are responsible for important survival techniques. Coauthor David Burr of the University of Sydney and the University of Florence gave an evolutionary perspective: “When we look around, we spontaneously perceive the form, size, movement and colour of a scene. Equally spontaneously, we perceive the number of items before us. This ability, shared with most other animals, is an evolutionary fundamental: It reveals immediately important quantities, such as how many apples there are on the tree, or how many enemies are attacking.”

Useful information, indeed, but our pupils seem to be more interested in the quantity of beers in the refrigerator.

Serious adventurers, however, get out of the city and go to Emory Decatur Hospital in – you guessed it – Decatur (unofficial motto: “Everything is Greater in Decatur”).

Find the emergency room and ask for Taylor Davis, who will be your personal guide. She’ll show you how to check in at the desk, sit in the waiting room for 7 hours, and then leave without seeing any medical personnel or receiving any sort of attention whatsoever. All the things she did when she went there in July for a head injury.

Ms. Davis told Fox5 Atlanta: “I didn’t get my vitals taken, nobody called my name. I wasn’t seen at all.”

But wait! There’s more! By booking your trip through LOTMEgo* and using the code “Decatur,” you’ll get the Taylor Davis special, which includes a bill/cover charge for $688.35 from the hospital. An Emory Healthcare patient financial services employee told Ms. Davis that “you get charged before you are seen. Not for being seen.”

If all this has you ready to hop in your car (really?), then check out LOTMEgo* on Twittbook and InstaTok. You’ll also find trick-or-treating tips and discounts on haunted hospital tours.

Breaking down the hot flash

Do you ever wonder why we scramble for cold things when we’re feeling nauseous? Whether it’s the cool air that needs to hit your face in the car or a cold, damp towel on the back of your neck, scientists think it could possibly be an evolutionary mechanism at the cellular level.

Motion sickness it’s actually a battle of body temperature, according to an article from LiveScience. Capillaries in the skin dilate, allowing for more blood flow near the skin’s surface and causing core temperature to fall. Once body temperature drops, the hypothalamus, which regulates temperature, tries to do its job by raising body temperature. Thus the hot flash!

The cold compress and cool air help fight the battle by counteracting the hypothalamus, but why the drop in body temperature to begin with?

There are a few theories. Dr. Robert Glatter, an emergency physician at Lenox Hill Hospital in New York, told LiveScience that the lack of oxygen needed in body tissue to survive at lower temperatures could be making it difficult to get oxygen to the body when a person is ill, and is “more likely an adaptive response influenced by poorly understood mechanisms at the cellular level.”

Another theory is that the nausea and body temperature shift is the body’s natural response to help people vomit.

Then there’s the theory of “defensive hypothermia,” which suggests that cold sweats are a possible mechanism to conserve energy so the body can fight off an intruder, which was supported by a 2014 study and a 2016 review.

It’s another one of the body’s many survival tricks.
 

Teachers were right: Pupils can do the math

Teachers liked to preach that we wouldn’t have calculators with us all the time, but that wound up not being true. Our phones have calculators at the press of a button. But maybe even calculators aren’t always needed because our pupils do more math than you think.

The pupil light reflex – constrict in light and dilate in darkness – is well known, but recent work shows that pupil size is also regulated by cognitive and perceptual factors. By presenting subjects with images of various numbers of dots and measuring pupil size, the investigators were able to show “that numerical information is intrinsically related to perception,” lead author Dr. Elisa Castaldi of Florence University noted in a written statement.

The researchers found that pupils are responsible for important survival techniques. Coauthor David Burr of the University of Sydney and the University of Florence gave an evolutionary perspective: “When we look around, we spontaneously perceive the form, size, movement and colour of a scene. Equally spontaneously, we perceive the number of items before us. This ability, shared with most other animals, is an evolutionary fundamental: It reveals immediately important quantities, such as how many apples there are on the tree, or how many enemies are attacking.”

Useful information, indeed, but our pupils seem to be more interested in the quantity of beers in the refrigerator.

No, Mr. Bond, I expect you to die

Movie watching usually requires a certain suspension of disbelief, and it’s safe to say James Bond movies require this more than most. Between the impossible gadgets and ludicrous doomsday plans, very few have ever stopped to consider the health risks of the James Bond universe.

Tumisu/Pixabay

Now, however, Bond, James Bond, has met his most formidable opponent: Wouter Graumans, a graduate student in epidemiology from the Netherlands. During a foray to Burkina Faso to study infectious diseases, Mr. Graumans came down with a case of food poisoning, which led him to wonder how 007 is able to trot across this big world of ours without contracting so much as a sinus infection.

Because Mr. Graumans is a man of science and conviction, mere speculation wasn’t enough. He and a group of coauthors wrote an entire paper on the health risks of the James Bond universe.

Doing so required watching over 3,000 minutes of numerous movies and analyzing Bond’s 86 total trips to 46 different countries based on current Centers for Disease Control and Prevention advice for travel to those countries. Time which, the authors state in the abstract, “could easily have been spent on more pressing societal issues or forms of relaxation that are more acceptable in academic circles.”

Naturally, Mr. Bond’s line of work entails exposure to unpleasant things, such as poison, dehydration, heatstroke, and dangerous wildlife (everything from ticks to crocodiles), though oddly enough he never succumbs to any of it. He’s also curiously immune to hangovers, despite rarely drinking anything nonalcoholic. There are also less obvious risks: For one, 007 rarely washes his hands. During one movie, he handles raw chicken to lure away a pack of crocodiles but fails to wash his hands afterward, leaving him at risk for multiple food-borne illnesses.

Of course, we must address the elephant in the bedroom: Mr. Bond’s numerous, er, encounters with women. One would imagine the biggest risk to those women would be from the various STDs that likely course through Bond’s body, but of the 27% who died shortly after … encountering … him, all involved violence, with disease playing no obvious role. Who knows, maybe he’s clean? Stranger things have happened.

The timing of this article may seem a bit suspicious. Was it a PR stunt by the studio? Rest assured, the authors addressed this, noting that they received no funding for the study, and that, “given the futility of its academic value, this is deemed entirely appropriate by all authors.” We love when a punchline writes itself.

In the longest study of bone loss in postmenopausal women to date, on average, bone mineral density (BMD) at the femoral neck (the most common location for a hip fracture) had dropped by 10% in 25 years – less than expected based on shorter studies.

Specifically, average BMD loss at the femoral neck was 0.4% per year during 25 years in this new study from Finland, compared with a drop of 1.6% per year over 15 years reported in other cohorts.

Five-year BMD change appeared to predict long-term bone loss. However, certain women had faster bone loss, indicating that they should be followed more closely.

“Although the average bone loss was 10.1% ... there is a significant variation in the bone loss rate” among women in the study, senior author Joonas Sirola, MD, PhD, associate professor, University of Eastern Finland, and coauthor Heikki Kröger, MD, PhD, a professor at the same university, explained to this news organization in an email, so “women with fast bone loss should receive special attention.

The findings from the Kuopio Osteoporosis Risk Factor and Prevention study by Anna Moilanen and colleagues were published online October 19 in the Journal of Bone and Mineral Research.

Several factors might explain the lower than expected drop in femoral neck BMD (the site that is used to diagnose osteoporosis), Dr. Sirola and Dr. Kröger said. BMD depends on a person’s age, race, sex, and genes. And compared with other countries, people in Finland consume more dairy products, and more postmenopausal women there take hormone replacement therapy (HRT).

“If otherwise indicated, HRT seemed to effectively protect from bone loss,” the researchers noted.

Also, the number of women who smoked or used corticosteroids was low, so bone loss in other populations may be higher. Moreover, the women who completed the study may have been healthier to start with, so the results should be interpreted with caution, they urge.

Nevertheless, the study sheds light on long-term changes in BMD in postmenopausal women and “stresses the importance of high peak bone mass before menopause and keeping a healthy weight” during aging to protect bone health, they say.

Indeed the work “changes our understanding of bone loss in older women,” said Dr. Kröger in a press release from the university.
 

Check BMD every 5 years after menopause

Invited to comment, American Society of Bone and Mineral Research President Peter R. Ebeling, MD, who was not involved with the research, noted key findings are that the rate of femoral neck bone loss after perimenopause was far less than previously expected, and 5-year BMD change appeared to predict long-term bone loss in postmenopausal women.

“We know bone loss begins 1 year before menopause and accelerates over the next 5 years,” Dr. Ebeling, from Monash University, Melbourne, added in an email. “This study indicates some stabilization of bone loss thereafter with lesser effects of low estrogen levels on bone.”

“It probably means bone density does not need to be measured as frequently following the menopause transition and could be every 5 years, rather than every 2 years, if there was concern about continuing bone loss.”
 

Baseline risk factors and long-term changes in BMD

For the study, researchers examined the association between risk factors for bone loss and long-term changes in femoral neck BMD in 2,695 women living in Kuopio who were 47 to 56 years old in 1989. The women were a mean age of 53 years, and 62% were postmenopausal.

They answered questionnaires and had femoral neck BMD measured by DEXA every 5 years.

A total of 2,695, 2,583, 2,482, 2,135, 1,305, and 686 women were assessed at baseline and 5-, 10-, 15-, 20- and 25-year follow-ups, respectively, indicating significant study drop-out by 25 years. 

By then, 17% of patients had died, 9% needed long-term care, some were unwilling to continue in the study, and others had factors that would have resulted in DEXA measurement errors (for example, hip implants, spine degeneration).

Researchers divided participants into quartiles of mean initial femoral neck BMD: 1.09 g/cm2, 0.97 g/cm2, 0.89 g/cm2, and 0.79 g/cm2, corresponding with quartiles 1 to 4 respectively (where quartile 1 had the highest initial femoral BMD and quartile 4 the lowest).

At 25 years, the mean femoral BMD had dropped to 0.97 g/cm2, 0.87 g/cm2, 0.80 g/cm2, and 0.73 g/cm2 in these respective quartiles.

Women lost 0.9%, 0.5%, 3.0%, and 1.0% of their initial BMD each year in quartiles 1 to 4, respectively.

And at 25 years, the women had lost 22.5%, 12.5%, 7.5%, and 2.5% of their initial BMD in the four quartiles, respectively.

Women in quartile 1 had the greatest drop in femoral BMD at 25 years, although their mean BMD at 25 years was higher than the mean initial BMD of the other women. 

The prevalence of bone-affecting diseases, smoking, and use of vitamin D/calcium supplementation, corticosteroids, or alcohol was similar in the four quartiles and was not associated with significant differences in annual bone loss.
 

The most important protective factor was HRT

However, body mass index (BMI) and HRT were significantly different in the four quartiles.

On average, women in quartile 1 had a mean BMI of 26.7 kg/m2 at baseline and 27.8 kg/m2 at 25 years. Women in quartile 4 (lowest initial BMD and lowest drop in BMD) had a mean BMI of 24.9 kg/m2 at baseline and 28.4 kg/m2 at 25 years.

Women in quartile 4 (lowest initial BMD and lowest drop in BMD) were more likely to take HRT than women in quartile 1 (highest initial BMD and highest drop in BMD), at 41% versus 26%, respectively.

“The average decrease in bone mineral density was lower than has been assumed on the basis of earlier, shorter follow-ups where the bone loss rate at the femoral neck has been estimated to be even more than 20%,” Dr. Sirola commented in the press release.

“There were also surprisingly few risk factors affecting bone mineral density. The most significant factor protecting against bone loss was hormone replacement therapy. Weight gain during the follow-up also protected against bone loss,” Dr. Sirola added.

The study was funded by the Academy of Finland, Finnish Ministry of Education and Culture, and the Päivikki and Sakari Sohlberg Foundation. The authors and Dr. Ebeling have reported no relevant financial relationships.

The number of suicides in 2020 declined in comparison to 2019, despite an increase in some risk factors associated with suicidal behavior, including pandemic-related job loss, financial strain, and deteriorating mental health, according to new federal statistics.

The number of annual suicides in the United States increased steadily from 2003 through 2018, followed by a 2% decline between 2018 and 2019. There was concern that deaths due to suicide would increase in 2020, but this doesn’t appear to be the case.

The provisional numbers show 45,855 deaths by suicide in the United States in 2020 – 3% lower than in 2019 (47,511), and 5% below the 2018 peak of 48,344 suicides, report Sally Curtin, MA, and colleagues with the National Center for Health Statistics, part of the U.S. Centers for Disease Control and Prevention.

The data were published online Nov. 3 in the National Vital Statistics System (NVSS) Vital Statistics Rapid Release.

On a monthly basis, the number of suicides was lower in 2020 than in 2019 in March through October and December – with the largest drop happening in April 2020 at a time when deaths from COVID-19 were peaking, the authors note. In April 2020, suicide deaths were 14% lower than in April 2019 (3,468 vs. 4,029).

The provisional age-adjusted suicide rate was 3% lower in 2020 (13.5 per 100,000) than in 2019 (13.9 per 100,000). It was 2% lower among men (21.9 compared with 22.4), and 8% lower for women (5.5 compared with 6.0).

Suicide rates among younger adults aged 10 to 34 years rose slightly between 2019 and 2020 but was only significant in those 25 to 34, with a 5% increase between 2019 and 2020.

Individuals aged 35 to 74 years had significant declines in suicide with the largest drop in those aged 45 to 54 years and 55 to 64 years.

Women in all race and Hispanic-origin groups showed declines in suicide rates between 2019 and 2020, but the decline was significant only among non-Hispanic white women (10%).

Suicide rates declined for non-Hispanic white and non-Hispanic Asian men but increased among non-Hispanic black, non-Hispanic American Indian or Alaska Native, and Hispanic men.

This analysis is based on more than 99% of expected death records. Based on previous patterns between provisional and final data, these provisional findings are expected to be consistent with final 2020 data, the authors say.

The number of suicides in 2020 declined in comparison to 2019, despite an increase in some risk factors associated with suicidal behavior, including pandemic-related job loss, financial strain, and deteriorating mental health, according to new federal statistics.

The number of annual suicides in the United States increased steadily from 2003 through 2018, followed by a 2% decline between 2018 and 2019. There was concern that deaths due to suicide would increase in 2020, but this doesn’t appear to be the case.

The provisional numbers show 45,855 deaths by suicide in the United States in 2020 – 3% lower than in 2019 (47,511), and 5% below the 2018 peak of 48,344 suicides, report Sally Curtin, MA, and colleagues with the National Center for Health Statistics, part of the U.S. Centers for Disease Control and Prevention.

The data were published online Nov. 3 in the National Vital Statistics System (NVSS) Vital Statistics Rapid Release.

On a monthly basis, the number of suicides was lower in 2020 than in 2019 in March through October and December – with the largest drop happening in April 2020 at a time when deaths from COVID-19 were peaking, the authors note. In April 2020, suicide deaths were 14% lower than in April 2019 (3,468 vs. 4,029).

The provisional age-adjusted suicide rate was 3% lower in 2020 (13.5 per 100,000) than in 2019 (13.9 per 100,000). It was 2% lower among men (21.9 compared with 22.4), and 8% lower for women (5.5 compared with 6.0).

Suicide rates among younger adults aged 10 to 34 years rose slightly between 2019 and 2020 but was only significant in those 25 to 34, with a 5% increase between 2019 and 2020.
