Women's Health

Letícia Soares was infected with COVID-19 in April 2020, in the final year of postdoctoral studies in disease ecology at a Canadian University. What started with piercing migraines and severe fatigue in 2020 soon spiraled into a myriad of long COVID symptoms: Gastrointestinal issues, sleep problems, joint and muscle pain, along with unexpected menstrual changes.

After an absence of menstrual bleeding and its usual signs, she later suffered from severe periods and symptoms that worsened her long COVID condition. “It just baffled me,” said Soares, now 39. “It was debilitating.”

Cases like Soares’s are leading scientists to spend more time trying to understand the biological sex disparity in chronic illnesses such as long COVID that until recently have all but been ignored. According to the Centers for Disease Control and Prevention, long COVID affects nearly twice as many women as men.

What’s more, up to two thirds of female patients with long COVID report an increase in symptoms related to menstruation, which suggests a possible link between sex hormone fluctuations and immune dysfunction in the illness.

“These illnesses are underfunded and understudied relative to their disease burdens,” said Beth Pollack, a research scientist at the Massachusetts Institute of Technology, Cambridge, Massachusetts, who studies complex chronic illnesses.

Addressing knowledge gaps, especially around sex differences, could significantly improve our understanding of complex chronic illnesses, said Pollack, who coauthored a 2023 literature review of female reproductive health impacts of long COVID.

Emerging ‘Menstrual Science’ Could Be Key

There is a critical need, she said, for studies on these illnesses to include considerations of sex differences, hormones, reproductive phases, and reproductive conditions. This research could potentially inform doctors and other clinicians or lead to treatments, both for reproductive symptoms and for the illnesses themselves.

Pollack noted that reproductive symptoms are prevalent across a group of infection-associated chronic illnesses she studies, all of which disproportionately affect women. These associated conditions, traditionally studied in isolation, share pathologies like reproductive health concerns, signaling a need for focused research on their shared mechanisms.

Recognizing this critical gap, “menstrual science” is emerging as a pivotal area of study, aiming to connect these dots through focused research on hormonal influences.

Researchers at the University of Melbourne, Melbourne, Australia, for example, are studying whether hormones play a role in causing or worsening the symptoms of long COVID. By comparing hormone levels in people with these conditions with those in healthy people and by tracking how symptoms change with hormone levels over time and across menstrual cycles, scientists hope to find patterns that could help diagnose these conditions more easily and lead to new treatments. They’re also examining how hormonal life phases such as puberty, pregnancy, or perimenopause and hormone treatments like birth control might affect these illnesses.

How Gender and Long COVID Intertwine

The pathologies of long COVID, affecting at least 65 million people worldwide, currently focus on four hypotheses: Persistent viral infection, reactivation of dormant viruses (such as common herpes viruses), inflammation-related damage to tissues and organs, and autoimmunity (the body attacking itself).

It’s this last reason that holds some of the most interesting clues on biological sex differences, said Akiko Iwasaki, PhD, a Yale University, New Haven, Connecticut, immunologist who has led numerous research breakthroughs on long COVID since the start of the pandemic. Women have two X chromosomes, for example, and although one is inactivated, the inactivation is incomplete.

Some cells still express genes from the “inactivated genes” on the X chromosome, Iwasaki said. Those include key immune genes, which trigger a more robust response to infections and vaccinations but also predispose them to autoimmune reactions. “It comes at the cost of triggering too much immune response,” Iwasaki said.

Sex hormones also factor in. Testosterone, which is higher in males, is immunosuppressive, so it can dampen immune responses, Iwasaki said. That may contribute to making males more likely to get severe acute infections of COVID-19 but have fewer long-term effects.

Estrogen, on the other hand, is known to enhance the immune response. It can increase the production of antibodies and the activation of T cells, which are critical for fighting off infections. This heightened immune response, however, might also contribute to the persistent inflammation observed in long COVID, where the immune system continues to react even after the acute infection has resolved.

Sex-Specific Symptoms and Marginalized Communities

Of the more than 200 symptoms long haulers experience, Iwasaki said, several are also sex-specific. A recent draft study by Iwasaki and another leading COVID researcher, David Putrino, PhD, at Mount Sinai Health System in New York City, shows hair loss as one of the most female-dominant symptoms and sexual dysfunction among males.

In examining sex differences, another question is why long COVID rates in the trans community are disproportionately high. One of the reasons Iwasaki’s lab is looking at testosterone closely is because anecdotal evidence from female-to-male trans individuals indicates that testosterone therapy improved their long COVID symptoms significantly. It also raises the possibility that hormone therapy could help.

However, patients and advocates say it’s also important to consider socioeconomic factors in the trans community. “We need to start at this population and social structure level to understand why trans people over and over are put in harm’s way,” said JD Davids, a trans patient-researcher with long COVID and the cofounder and codirector of Strategies for High Impact and its Long COVID Justice project.

For trans people, said Davids, risk factors for both severe COVID and long COVID include being part of low-income groups, belonging to marginalized racial and ethnic communities, and living in crowded environments such as shelters or prisons.

The disproportionate impact of long COVID on marginalized communities, especially when seen through the lens of historical medical neglect, also demands attention, said Iwasaki. “Women used to be labeled hysteric when they complained about these kinds of symptoms.”

Where It All Leads

The possibility of diagnosing long COVID with a simple blood test could radically change some doctors’ false perceptions that it is not a real condition, Iwasaki said, ensuring it is recognized and treated with the seriousness it deserves.

“I feel like we need to get there with long COVID. If we can order a blood test and say somebody has a long COVID because of these values, then suddenly the diseases become medically explainable,” Iwasaki added. This advancement is critical for propelling research forward, she said, refining treatment approaches — including those that target sex-specific hormone, immunity, and inflammation issues — and improving the well-being of those living with long COVID.

This hope resonates with scientists like Pollack, who recently led the first National Institutes of Health-sponsored research webinar on less studied pathologies in myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) and long COVID, and with the experiences of individuals like Soares, who navigates through the unpredictable nature of both of these conditions with resilience.

“This illness never ceases to surprise me in how it changes my body. I feel like it’s a constant adaptation,” said Soares. Now living in Salvador, Brazil, her daily life has dramatically shifted to the confines of her home.

“It’s how I have more predictability in my symptoms,” she said, pointing out the pressing need for the scientific advancements that Iwasaki envisions and a deepening of our understanding of the disease’s impacts on patients’ lives.

Long-term adherence to a plant-based diet was not tied to a greater risk of hip fracture and some plant-based regimens may actually reduce the risk, a large cohort study of postmenopausal women in the United States suggested.

Not all plant-centered regimens are healthful, however, and this study factored dietary quality into risk.

Writing in JAMA Network Open, the study authors compared the lowest to highest quintiles of Plant-Based Diet Index scores. They found the most recent intake of a healthy plant-based diet (hPDI) to be associated with a somewhat lower (21%) risk of fracture while the most recent intake of its unhealthy counterpart (uPDI) was linked to a somewhat higher (28%) risk.

“In addition, higher baseline scores in the uPDI were associated with higher risk of hip fracture,” wrote the researchers, led by Mercedes Sotos Prieto, PhD, a nutritional epidemiologist in the Department of Preventive Medicine and Public Health at the Autonomous University of Madrid.

Plant-based diets, characterized by higher consumption of plant foods and lower or no intake of animal foods, have raised concerns about their potential harm to bone health. In a recent meta-analysis, vegetarians, but particularly vegans with no consumption of any animal food, had a higher fracture risk and lower bone mineral density compared with omnivores.

Another study found that compared with meat eaters, fish eaters and vegetarians had a higher risk of hip fractures. These analyses, however, did not assess the quality of the plant-based diets.

“We hypothesized that the differences in the quality of the plant-based diets — whole grains, fruits, and vegetables vs refined carbohydrates or snacks, which are both plant-based but very different, would be important in the association for the risk of hip fracture,” Dr. Sotos Prieto said in an interview.
 

Study details

Her study drew on data from 70,285 postmenopausal White women who were in the US Nurses’ Health Study from 1984 through 2014; data were analyzed from Jan. 1 to July 31, 2023.

The mean age of the nurses was 54.92 years, and 2038 cases of hip fracture were reported during the study over as long as 30 years of follow-up.

Healthy plant foods included whole grains, fruits, vegetables, nuts, legumes, vegetable oils, and tea or coffee and received positive scores, whereas less healthy plant foods such as fruit juices, sweetened beverages, refined grains, potatoes, sweets, or desserts and animal foods received reversed scores. Dietary and lifestyle information was collected by self-reported questionnaires.

Individuals with higher hPDI scores were leaner, more physically active, less likely to be smokers, and more likely to use vitamin and calcium supplements. Not surprisingly, they also had higher intakes of dietary calcium and healthy plant foods and had lower intake of less healthy plant foods. “It’s plausible that reverse causation may account for the risk associations, as individuals with underlying health conditions that predisposed them to higher fracture risk may have changed their diet,” Dr. Sotos Prieto said. “In addition, baseline diet may reflect diet early on, which could be an important predictor of bone mineral density when there was more active bone turnover.”

Lack of information precluded adjustment for the use of anti-osteoporotic medication.

Neither the hPDI, with a hazard ratio (HR) for highest vs lowest quintile of 0.97 (95% confidence interval, 0.83-1.14) nor the uPDI, with an HR for highest vs lowest quintile of 1.02 (95% CI, 0.87-1.20) for diet adherence over the long term was associated with hip fracture risk.

For recent dietary intake in the highest vs lowest quintiles, however, the hPDI was associated with a 21% lower risk of hip fracture: HR, 0.79 (95% CI, 0.68-0.92; P = .02 for trend). In contrast, the uPDI was associated with a 28% higher risk: HR, 1.28 (95% CI, 1.09-1.51; P = .008 for trend).

Future studies in other populations are needed to confirm the results and enhance their generalizability, Dr. Sotos Prieto said. “Investigating the temporal dynamics of dietary patterns and their effects by examining how recent dietary changes may impact health outcomes over different timeframes is important.” In the meantime, people wishing to follow a plant-based diet should make sure it features high-quality foods.

TOPLINE:

Taking a prescription opioid for pain management during pregnancy is associated with an increased risk for spontaneous preterm birth, data from a new case-control study of over 25,000 Medicaid patients showed.

METHODOLOGY:

• Researchers retrospectively reviewed data on pregnant patients enrolled in Tennessee Medicaid who experienced birth of a single baby at ≥ 24 weeks gestation (25,391 with opioid use disorder and 225,696 without).
• Median age of participants was 23 years; 58.1% were non-Hispanic White, 38.7% Black, 2.6% Hispanic, and 0.5% Asian.
• Controls were matched based on pregnancy start date, race, ethnicity, age at delivery (within 2 years), and history of prior preterm birth.
• Sensitivity analysis included the exclusion of opioid prescriptions dispensed within 3 days of the index date to account for potential opioid prescribing associated with labor pain.

TAKEAWAY:

• A total of 18,702 patients (7.4%) filled an opioid prescription during the 60 days prior to the index date.
• Each doubling of opioid morphine milligram equivalents (MMEs) prescribed during the 60 days was associated with a 4% increase in the odds of spontaneous preterm birth compared with no opioid exposure in the matched controls (adjusted odds ratio [aOR], 1.04; 95% CI, 1.01-1.08).
• Overall, 1573 pregnancies filled prescriptions for 900 MMEs or greater, which was associated with at least a 21% increased risk for spontaneous preterm birth compared with no opioid exposure (aOR, 1.21; 95% CI, 1.10-1.33).
• Researchers found no significant difference in odds of spontaneous preterm birth among included opioid types after adjusting for confounders and opioid MMD.

IN PRACTICE:

“This association may appear modest, especially considering that common, one-time prescriptions often fall in the 150-225 MME range, but these findings may provide more caution when prescribing multiple, higher strength opioids,” the authors wrote. “We also caution against the conclusion that lower doses, especially those below 100 MME, are safe; the confidence bands over the low dose range still include odds ratios that are consistent with meaningful harm.”

Sarah S. Osmundson, MD, MS, of the Department of Obstetrics and Gynecology, Vanderbilt University Medical Center, Nashville, Tennessee, was the senior and corresponding author on the study. The study was published online on February 14 in JAMA Network Open.

LIMITATIONS:

Data are based on opioids prescribed and lack detail on actual use of opioids and nonprescription analgesics. Findings may not be generalizable to other populations or settings outside Medicaid.

TOPLINE:

Doxorubicin increases the risk for breast cancer in women with Hodgkin lymphoma, suggesting the need for increased surveillance.

METHODOLOGY:

• Doxorubicin is a mainstay of Hodgkin lymphoma treatment.
• Studies suggest that girls with Hodgkin lymphoma who receive doxorubicin have a higher risk for breast cancer later in life, but it is unclear if women treated as adults face that same risk.
• To find out, investigators reviewed breast cancer incidence in 1964 Dutch women, ages 15-50, who were treated for Hodgkin lymphoma from 1975 to 2008.
• Patients had survived for at least 5 years, and 57% received doxorubicin.

TAKEAWAY:

• Women treated with doxorubicin had a 40% higher risk for breast cancer, and that risk was independent of age of treatment, receipt of chest radiation, and the use of gonadotoxic agents.
• The risk for breast cancer with doxorubicin was dose-dependent, with each 100 mg/m2 dose increment increasing the risk by 18%.
• The findings held whether women were treated years ago or more recently, despite the evolution of treatment strategies for Hodgkin lymphoma.
• After 30 years of follow-up, nearly one in five survivors (20.8%) developed breast cancer. It took 20 years for the elevated risk for breast cancer following treatment with doxorubicin to emerge.

IN PRACTICE:

The study suggests that adolescent and adult women survivors of Hodgkin lymphoma who received doxorubicin have an increased risk for breast cancer, and this risk is independent of age at first Hodgkin lymphoma treatment, receipt of chest radiotherapy, and gonadotoxic treatment, the authors concluded. “Our results have implications for [breast cancer] surveillance guidelines for [Hodgkin lymphoma] survivors and treatment strategies for patients with newly diagnosed” Hodgkin lymphoma.

SOURCE:

The study, led by Suzanne Neppelenbroek of the Netherlands Cancer Institute, Amsterdam, was published February 15 in the Journal of Clinical Oncology. 

LIMITATIONS:

Recruitment ended in 2008 before the advent of newer treatments such as antibody-drug conjugates and immune checkpoint inhibitors.

DISCLOSURES:

The work was funded by the Dutch Cancer Society. Several authors reported ties to Lilly, AbbVie, Amgen, and other companies.

Food emulsifiers are among the most widespread food additives. A large cohort study highlighted an association between the consumption of certain emulsifiers and an increased risk for certain cancers, particularly breast and prostate cancer.

Ultraprocessed foods constitute a significant part of our diet, representing approximately 30% of energy intake in France.

Large epidemiologic studies have already linked diets rich in ultraprocessed products to an increased risk for cardiovascular diseases, diabetes, obesity, and mortality. Possible explanations for this association include the presence of additives, particularly emulsifiers. These additives are intended to improve the texture and shelf life of foods.

Recent experimental studies have shown that emulsifiers alter the gut microbiota and may lead to low-grade inflammation. Dysbiosis and chronic inflammation not only increase the risk for inflammatory bowel diseases but are also implicated in the etiology of several other chronic pathologies and certain extraintestinal cancers.

The NutriNet-Santé study provided extensive information on the dietary habits of > 100,000 French participants. A new analysis was conducted, examining the possible link between the presence of emulsifiers in the diet and cancer occurrence. Data from 92,000 participants (78.8% women) were utilized. They covered an average follow-up of 6.7 years, during which 2604 cancer cases were diagnosed, including 750 breast cancers, 322 prostate cancers, and 207 colorectal cancers.

In this cohort, the risk for cancer increased with a higher presence in the diet of products containing certain emulsifiers widely used in industrial food in Europe: Carrageenans (E407), mono- and diglycerides of fatty acids (E471), pectins (E440), and sodium carbonate (E500).

Notably, the highest consumption of mono- and diglycerides of fatty acids (E471) was associated with a 15% increase in the risk for all types of cancer, a 24% increase in breast cancer risk, and a 46% increase in prostate cancer risk. The highest consumption of carrageenans (E407) was associated with a 28% increase in breast cancer risk.

In an analysis by menopausal status, the risk for breast cancer before menopause was associated with high consumption of diphosphates (E450; 45% increase), pectins (E440; 55% increase), and sodium bicarbonate (E500; 48% increase). No link was found between emulsifier consumption and colorectal cancer risk. While some associations were observed for other emulsifiers, they did not persist in sensitivity analyses.

The European Food Safety Agency recently evaluated the risks of emulsifiers, however, and found no safety issues or need to limit daily consumption of several of them, notably E471.

It is certain that cancer is multifactorial, and a single factor (here, exposure to emulsifiers) will not significantly increase the risk. However, while not essential to human health, emulsifiers are widely prevalent in the global market. Therefore, if causality is established, the increased risk could translate into a significant number of preventable cancers at the population level. Confirmation of this causal link will need to be obtained through experimental and epidemiological studies.

“She’s, like, 90 years old. I’m not going to ask her about sex!” says the cringing resident. “She’s older than my grandmother!”

Well, my young friend, our 80- and 90-year-old patients were in their 20s and 30s in the 1960s. You can bet some of them were pretty groovy! A Swedish study of septuagenarians revealed a shift in sexual attitudes: from 5% of 70-year-old women in the 1970s citing sex as a positive aspect of life, to 78% in 2000. Those of us in practice who came of age during the AIDS era and alongside the purity movement of the 1990s can be more sexually reserved than our grandparents. We might need to catch up. In fact, in another study, 82% of 97-year-old female participants felt that being asked about their sexuality in healthcare settings was positive.

While changes do occur in sexual physiology and behavior with age, satisfying sexual engagement may be an important factor in the general well-being and overall health of older women. Given the high prevalence of dementia among this population, it may be useful to know that positive sexual expression may delay cognitive decline. We also have evidence that sexual satisfaction is important for relational health, which in turn helps predict physical health.

Shed the Dysfunction Mindset

Our medical bias has been that a fulfilling sexual life requires a hard penis and a lubricated vagina. This view of the range of healthy and satisfying sexual expression is lamentably limited. Older adults may have more problems with physiologic arousal in the form of more erectile dysfunction and decreased vaginal lubrication, but these issues may lead to partnerships in which there is less insertive/receiving sexual play and more oral sex, cuddling, kissing, and other forms of partnered sexual play. Older adults may focus less on performance and more on intimacy. In fact, as heterosexual couples encounter these physiologic changes, their sexual behavior may begin to focus more attention to female pleasure. Good news for older women!

As described by Dutch sexuality and aging expert Woet Gianotten, MD, older adults have a lot going for them in their sex lives. Many are retired with more time available, less work stress, greater comfort and familiarity with their partners, and less insecurity about their bodies.

Common Concerns

Many older adults are having satisfying sexual play and are less bothered by changes in their sexual physiology. Still, for those who aren’t happy with their sex lives, clinicians must be ready to address these concerns.

Nancy, an 87-year-old patient whose husband died 5 years ago after 59 years of marriage, has just met someone new. When they are intimate physically, she’s not feeling aroused in the way she recalls, and wonders, Where have my orgasms gone?

A host of physical changes among older women can affect the sexual experience, including the vulvovaginal changes of genitourinary syndrome of menopause (GSM), incontinence, uterine prolapse, diminished sensation, and reduced overall mobility. Although aging is responsible for some of these changes, chronic diseases and medical treatments can play an even larger role.

GSM is a major contributor to sexual pain, genital irritation, and reduced arousal and orgasm. It’s crazy that we don’t ask about and treat GSM. Beyond the sexual impact, the vaginal dryness of GSM can contribute to urinary tract infections, which can lead to sepsis and even death! Vaginal estrogens and other GSM treatments are safe and effective in the vast majority of women. Vaginal moisturizers, vaginal dilators, and increasing genital blood flow also help improve GSM.

Vaginal dilators are used in the management of vaginal stenosis, when the vaginal skin has contracted as a result of GSM or pelvic radiation to treat cancer. Dilators are also used to treat some forms of high-tone pelvic floor dysfunction. For expert guidance and coaching on the use of dilators, seek out sexual medicine specialists and pelvic floor physical therapists. Pelvic floor physical therapy is important in the management of a wide range of sexual concerns, from reduced arousal and orgasm to almost any kind of sexual pain.

For postmenopausal women who are distressed by hypoactive sexual desire disorder, transdermal low-dose testosterone may be considered when other causes of low libido have been ruled out.

Due to changes in nerve fiber sensitivity over time, older age is an ideal phase of life to incorporate higher-intensity vibration and other sexual devices into solo and partner sex. Mobility limitations and joint pain can be addressed with devices designed specifically for this purpose or with the use of pillows and other supports.

As Betty Dodson, a staunch advocate for women’s pleasure until her death in 2020 at 91, wisely said, “Masturbation will get you through childhood, puberty, romance, marriage, and divorce, and it will see you through old age.” We can encourage women to see sexual play and pleasure flexibly, as a lifelong process of self-knowledge and discovery.

Basic Tips for Patients

• More “fiction and friction,” as coined by sex therapist Barry McCarthy, is necessary. As bodies age, more stimulation, both mental and physical, is necessary and often requires more direct physical stimulation of genitals.
• More time: Everything seems to take more time as we age; sex is no different.
• Incontinence concerns can be addressed by open communication and collaboration with partners, and being prepared with waterproof pads for the bed and towels.
• Ask about medical intervention–related sexual side effects. A wide range of medications can decrease desire and arousal and delay orgasm. If a change in sexual function occurred with starting a medication, it may be worthwhile investigating alternatives or, if possible, discontinuing a medication. Surgical and procedural changes to the anatomy also can affect sexual function. While correction may be impossible once certain changes have occurred, clinicians can provide patients with both validation about the problem and hope that, for the most part, with creativity and flexibility, pleasurable sexual experience is possible in all bodies.

Older adults may focus less on performance and more on intimacy. In fact, as heterosexual couples encounter these physiologic changes, their sexual behavior may begin to focus more attention to female pleasure. Good news for older women!

As described by Dutch sexuality and aging expert Woet Gianotten, MD, older adults have a lot going for them in their sex lives. Many are retired with more time available, less work stress, greater comfort and familiarity with their partners, and less insecurity about their bodies.

Common Concerns

Many older adults are having satisfying sexual play and are less bothered by changes in their sexual physiology. Still, for those who aren’t happy with their sex lives, clinicians must be ready to address these concerns.

Nancy, an 87-year-old patient whose husband died 5 years ago after 59 years of marriage, has just met someone new. When they are intimate physically, she’s not feeling aroused in the way she recalls, and wonders, Where have my orgasms gone?

A host of physical changes among older women can affect the sexual experience, including the vulvovaginal changes of genitourinary syndrome of menopause (GSM), incontinence, uterine prolapse, diminished sensation, and reduced overall mobility. Although aging is responsible for some of these changes, chronic diseases and medical treatments can play an even larger role.

GSM is a major contributor to sexual pain, genital irritation, and reduced arousal and orgasm. It’s crazy that we don’t ask about and treat GSM. Beyond the sexual impact, the vaginal dryness of GSM can contribute to urinary tract infections, which can lead to sepsis and even death! Vaginal estrogens and other GSM treatments are safe and effective in the vast majority of women. Vaginal moisturizers, vaginal dilators, and increasing genital blood flow also help improve GSM.

Vaginal dilators are used in the management of vaginal stenosis, when the vaginal skin has contracted as a result of GSM or pelvic radiation to treat cancer. Dilators are also used to treat some forms of high-tone pelvic floor dysfunction. For expert guidance and coaching on the use of dilators, seek out sexual medicine specialists and pelvic floor physical therapists. Pelvic floor physical therapy is important in the management of a wide range of sexual concerns, from reduced arousal and orgasm to almost any kind of sexual pain.

For postmenopausal women who are distressed by hypoactive sexual desire disorder, transdermal low-dose testosterone may be considered when other causes of low libido have been ruled out.

Due to changes in nerve fiber sensitivity over time, older age is an ideal phase of life to incorporate higher-intensity vibration and other sexual devices into solo and partner sex. Mobility limitations and joint pain can be addressed with devices designed specifically for this purpose or with the use of pillows and other supports.

As Betty Dodson, a staunch advocate for women’s pleasure until her death in 2020 at 91, wisely said, “Masturbation will get you through childhood, puberty, romance, marriage, and divorce, and it will see you through old age.” We can encourage women to see sexual play and pleasure flexibly, as a lifelong process of self-knowledge and discovery.

Basic Tips for Patients

• More “fiction and friction,” as coined by sex therapist Barry McCarthy, is necessary. As bodies age, more stimulation, both mental and physical, is necessary and often requires more direct physical stimulation of genitals.
• More time: Everything seems to take more time as we age; sex is no different.
• Incontinence concerns can be addressed by open communication and collaboration with partners, and being prepared with waterproof pads for the bed and towels.
• Ask about medical intervention–related sexual side effects. A wide range of medications can decrease desire and arousal and delay orgasm. If a change in sexual function occurred with starting a medication, it may be worthwhile investigating alternatives or, if possible, discontinuing a medication. Surgical and procedural changes to the anatomy also can affect sexual function. While correction may be impossible once certain changes have occurred, clinicians can provide patients with both validation about the problem and hope that, for the most part, with creativity and flexibility, pleasurable sexual experience is possible in all bodies.

“She’s, like, 90 years old. I’m not going to ask her about sex!” says the cringing resident. “She’s older than my grandmother!”

Well, my young friend, our 80- and 90-year-old patients were in their 20s and 30s in the 1960s. You can bet some of them were pretty groovy! A Swedish study of septuagenarians revealed a shift in sexual attitudes: from 5% of 70-year-old women in the 1970s citing sex as a positive aspect of life, to 78% in 2000. Those of us in practice who came of age during the AIDS era and alongside the purity movement of the 1990s can be more sexually reserved than our grandparents. We might need to catch up. In fact, in another study, 82% of 97-year-old female participants felt that being asked about their sexuality in healthcare settings was positive.

While changes do occur in sexual physiology and behavior with age, satisfying sexual engagement may be an important factor in the general well-being and overall health of older women. Given the high prevalence of dementia among this population, it may be useful to know that positive sexual expression may delay cognitive decline. We also have evidence that sexual satisfaction is important for relational health, which in turn helps predict physical health.

NATIONAL HARBOR, MARYLAND — Rates of maternal morbidity in individuals with placenta accreta were similar with alternative strategies to cesarean hysterectomy regardless of the severity of the condition, based on data from 60 individuals.

Currently, the recommended management strategy for placenta accreta spectrum (PAS) is a cesarean hysterectomy, but data are lacking on alternative strategies, especially for individuals wishing to keep their uterus and potentially preserve fertility, Farah H. Amro, MD, of the University of Texas Health Science Center at Houston McGovern Medical School said in a presentation at the Pregnancy Meeting (abstract 70).

Alternative options are being studied worldwide, including delayed hysterectomy (typically performed at 4-6 weeks postpartum), Dr. Amro said at the meeting, which was sponsored by the Society for Maternal-Fetal Medicine.

At UT Houston, delayed hysterectomy is performed for more aggressive PAS that involves parametrial invasion, and the placenta left in situ until resorption/passage for those wishing to keep their uterus, Dr. Amro said in an interview.

In a cohort study at UT Houston, a level IV academic center, Dr. Amro and colleagues evaluated outcomes in 60 individuals with suspected PAS who were given three management options after extensive counseling. Of these, 29 opted for a cesarean hysterectomy (CH); 16 opted for delayed interval hysterectomy (IH) performed 4-6 weeks after delivery; and 15 individuals with a preference for uterine preservation were assigned to conservative management.

The study occurred between January 2020 and July 2023. The primary outcome was composite maternal morbidity, which was further divided into composite acute morbidity (within 24 hours from cesarean delivery or hysterectomy) and composite delayed morbidity (24 hours or more postoperatively). Secondary outcomes included total estimated blood loss, need for blood transfusion, unplanned hospital readmission, and pathology diagnosis.

Overall maternal morbidity rates were 55%, 56%, and 53% in the CH, IH, and CM groups, respectively, although those who were planned for IH and CM had more severe PAS.

The planned procedure was performed in 90% of the CH patients. Approximately 20% of patients in the IH and CM groups underwent unplanned procedures. No cases of sepsis or maternal death occurred, and uterine infection rates were 0%, 6%, and 13% in the CH, IH, and CM groups, respectively.

Patients in the CM and IH groups were significantly less likely to require blood transfusions than those in the CH group. In addition, composite delayed morbidity (24 hours or more after surgery) was similar among the groups, with rates of 31%, 38%, and 33% for CH, IH, and CM, respectively (P = .94). These results are important, given the concerns regarding leaving a placenta in situ after cesarean delivery, said Dr. Amro.

The findings were limited by several factors including the use of data from a single site, the lack of randomization, patient compliance, and cost effectiveness. However, the results were strengthened by the diverse population and comparison of novel approaches that aren’t frequently utilized In the United States, as well as the large volume of PAS cases treated in a relatively short time frame, Dr. Amro said.
 

More Options Empower Mothers

Overall, the results support the use of delayed hysterectomy and conservative management as safe alternatives to cesarean hysterectomy, especially in those with severe PAS (opting for IH Instead of CH) and those seeking to preserve the uterus (CM), Dr. Amro said. However, these alternative options can be offered only to patients who can engage in frequent postpartum follow-up and live close to the hospital; with the CM group, resorption/passage of the placenta may take as long as 6 months in some cases, she explained.

The greatest concerns with leaving the placenta in place in PAS patients are the risk of infection or subsequent hemorrhage, Dr. Amro said in an interview. However, the current study showed that the infection rate was not as high as anticipated, and the frequency of unplanned procedures occurred in only 20%, which should alleviate some of these concerns, she said.

“We have completed 28 cases of conservative management since 2015, four have gone on to successful pregnancy with no cases of PAS in the subsequent pregnancies,” Dr. Amro said. Conservative management gives mothers another option, she added. “Moms feel empowered by being given a choice, especially for those that want to keep their uterus for fertility or religious/cultural considerations, and many opt for CM.”

The next step is to take the conservative management strategy to larger groups at other centers to replicate the results in other locations, said Dr. Amro. “Also, we are looking at the utility of other interventions such as uterine artery embolization and performing delayed dilation and curettage to help with passage of the placenta in those opting for CM.”
 

Study Supports Safety of Conservative Management

“There are patients that may want to preserve their reproductive organs in the face of an accreta (such as for religious, cultural, and personal reasons), and this study helps address some of the safety considerations with conservative approaches,” Corrina M. Oxford-Horrey, MD, a maternal-fetal medicine specialist at Weill Cornell Medicine, New York, said in an interview.

“I was surprised that there was not a lot of infectious morbidity (such as sepsis) in the cohorts; that was helpful to see,” said Dr. Oxford-Horrey, who served as a moderator for the session in which the study was presented.

Based on the study findings, “nontraditional approaches to placenta accreta spectrum management may be reasonable, given similar overall postoperative composite morbidity between the groups,” she said.

As for additional research, replicating the study in a multicenter fashion would add to the generalizability of the findings, Dr. Oxford-Horrey said.

The study received no outside funding. The researchers and Dr. Oxford-Horrey had no financial conflicts to disclose.

The American Cancer Society has just published its cancer statistics for 2024. This is an annual report, the latest version of which has some alarming news for gastroenterologists. Usually, we think of being “number one” as a positive thing, but that’s not the case this year when it comes to the projections for colorectal cancer.

But first, let’s discuss the report’s overall findings. Broadly speaking, the news is quite good in that there’s been an aversion of over 4 million deaths since 1991. That decline over the past four decades is due to reductions in smoking, earlier detection, and improved screening and treatments for localized or metastatic disease. But these gains are now threatened by some offsets that we’re seeing, with increasing rates of six of the top 10 cancers in the past several years.
 

Increasing Rates of Gastrointestinal Cancers

The incidence rate of pancreas cancer has increased from 0.6% to 1% annually.

Pancreas cancer has a 5-year relative survival rate of 13%, which ranks as one of the three worst rates for cancers. This cancer represents a real screening challenge for us, as it typically presents asymptomatically.

Women have experienced a 2%-3% annual increase in incidence rates for liver cancer.

I suspect that this is due to cases of fibrotic liver disease resulting from viral hepatitis and metabolic liver diseases with nonalcoholic fatty liver and advanced fibrosis (F3 and F4). These cases may be carried over from before, thereby contributing to the increasing incremental cancer risk.

We can’t overlook the need for risk reduction here and should focus on applying regular screening efforts in our female patients. However, it’s also true that we require better liver cancer screening tests to accomplish that goal.
 

In Those Under 50, CRC the Leading Cause of Cancer Death in Men, Second in Women

I really want to focus on the news around colorectal cancer.

To put this in perspective, in the late 1990s, colorectal cancer was the fourth leading cause of death in men and women. The current report extrapolated 2024 projections using the Surveillance, Epidemiology, and End Results (SEER) database ending in 2020, which was necessary given the incremental time it takes to develop cancers. The SEER database suggests that in 2024, colorectal cancer in those younger than 50 years of age will become the number-one leading cause of cancer death in men and number-two in women. The increasing incidence of colorectal cancer in younger people is probably the result of a number of epidemiologic and other reasons.

The current report offers evidence of racial disparities in cancer mortality rates in general, which are twofold higher in Black people compared with White people, particularly for gastric cancer. There is also an evident disparity in Native Americans, who have higher rates of gastric and liver cancer. This is a reminder of the increasing need for equity to address racial disparities across these populations.

But returning to colon cancer, it’s a marked change to go from being the fourth-leading cause of cancer death in those younger than 50 years of age to being number one for men and number two for women.

Being “number one” is supposed to make you famous. This “number one,” however, should in fact be infamous. It’s a travesty, because colorectal cancer is a potentially preventable disease.

As we move into March, which happens to be Colorectal Cancer Awareness Month, hopefully this fires up some of the conversations you have with your younger at-risk population, who may be reticent or resistant to colorectal cancer screening.

We have to do better at getting this message out to that population at large. “Number one” is not where we want to be for this potentially preventable problem.

This transcript has been edited for clarity.

The American Cancer Society has just published its cancer statistics for 2024. This is an annual report, the latest version of which has some alarming news for gastroenterologists. Usually, we think of being “number one” as a positive thing, but that’s not the case this year when it comes to the projections for colorectal cancer.

But first, let’s discuss the report’s overall findings. Broadly speaking, the news is quite good in that there’s been an aversion of over 4 million deaths since 1991. That decline over the past four decades is due to reductions in smoking, earlier detection, and improved screening and treatments for localized or metastatic disease. But these gains are now threatened by some offsets that we’re seeing, with increasing rates of six of the top 10 cancers in the past several years.
 

Increasing Rates of Gastrointestinal Cancers

The incidence rate of pancreas cancer has increased from 0.6% to 1% annually.

Pancreas cancer has a 5-year relative survival rate of 13%, which ranks as one of the three worst rates for cancers. This cancer represents a real screening challenge for us, as it typically presents asymptomatically.

Women have experienced a 2%-3% annual increase in incidence rates for liver cancer.

I suspect that this is due to cases of fibrotic liver disease resulting from viral hepatitis and metabolic liver diseases with nonalcoholic fatty liver and advanced fibrosis (F3 and F4). These cases may be carried over from before, thereby contributing to the increasing incremental cancer risk.

We can’t overlook the need for risk reduction here and should focus on applying regular screening efforts in our female patients. However, it’s also true that we require better liver cancer screening tests to accomplish that goal.
 

In Those Under 50, CRC the Leading Cause of Cancer Death in Men, Second in Women

I really want to focus on the news around colorectal cancer.

To put this in perspective, in the late 1990s, colorectal cancer was the fourth leading cause of death in men and women. The current report extrapolated 2024 projections using the Surveillance, Epidemiology, and End Results (SEER) database ending in 2020, which was necessary given the incremental time it takes to develop cancers. The SEER database suggests that in 2024, colorectal cancer in those younger than 50 years of age will become the number-one leading cause of cancer death in men and number-two in women. The increasing incidence of colorectal cancer in younger people is probably the result of a number of epidemiologic and other reasons.

The current report offers evidence of racial disparities in cancer mortality rates in general, which are twofold higher in Black people compared with White people, particularly for gastric cancer. There is also an evident disparity in Native Americans, who have higher rates of gastric and liver cancer. This is a reminder of the increasing need for equity to address racial disparities across these populations.

But returning to colon cancer, it’s a marked change to go from being the fourth-leading cause of cancer death in those younger than 50 years of age to being number one for men and number two for women.

Being “number one” is supposed to make you famous. This “number one,” however, should in fact be infamous. It’s a travesty, because colorectal cancer is a potentially preventable disease.

As we move into March, which happens to be Colorectal Cancer Awareness Month, hopefully this fires up some of the conversations you have with your younger at-risk population, who may be reticent or resistant to colorectal cancer screening.

We have to do better at getting this message out to that population at large. “Number one” is not where we want to be for this potentially preventable problem.

TOPLINE:

Women with steatotic liver disease (SLD) related to alcohol consumption are at greater risk of mortality than men with the same condition, new research suggested.

METHODOLOGY:

• Researchers analyzed data from the US National Health and Nutrition Examination Survey III (NHANES III, 1988-1994), which included standardized ultrasonographic measures of hepatic steatosis, assessment of cardiometabolic risk traits, and questionnaire data on alcohol intake.
• Among 10,007 participants aged 20 years and older (mean age, 42 years; 50.3% men) who were included and followed for a median of 26.7 years, 1461 had metabolic dysfunction–associated steatotic liver disease (MASLD), 105 alcohol-related liver disease (ALD), 225 metabolic dysfunction-associated and alcohol-related liver disease (MetALD), 180 other types of SLD, and 8036 no SLD.
• Researchers examined SLD-associated risks for all-cause mortality after adjustment for baseline age, smoking status, systolic blood pressure, antihypertensives, type 2 diabetes, diabetic medication use, body mass index, total cholesterol, high-density lipoprotein cholesterol, lipid-lowering therapy, race, and family income.

TAKEAWAY:

• In men, the prevalence of MASLD, MetALD, and ALD was 18.5%, 3.2%, and 1.7%, respectively, whereas the corresponding prevalence among women was 10.3%, 1.2%, and 0.3%, respectively.
• In multivariable-adjusted survival analyses, MASLD was not significantly associated with all-cause mortality for either sex compared with those without SLD.
• In contrast, MetALD was associated with an 83% higher hazard of all-cause mortality in women (hazard ratio [HR], 1.83), but not significantly associated with mortality in men.
• ALD was significantly associated with all-cause mortality in both sexes, with a greater magnitude in women than men (HRs, 3.49 vs 1.89, respectively) — the equivalent of about a 160% higher mortality risk for women.
• With regard to SLD severity, the trend across worsening phenotypes (ie, MASLD, MetALD, or ALD) was significant for sex differences in mortality but not in prevalence.

IN PRACTICE:

“Because alcohol consumption is modifiable, limiting alcohol intake particularly in women at risk for SLD could be critical as part of efforts to mitigate mortality risk in patients with SLD,” the authors wrote.

SOURCE:

The study, led by Hongwei Ji of Qingdao University, Qingdao, Shandong, China, and Susan Cheng, MD, Cedars-Sinai Medical Center, Los Angeles, was published in the February issue of Journal of Hepatology.

LIMITATIONS:

The study data came from NHANES III, which was conducted between 1988 and 1994. This is a potential limitation, as the prevalence of metabolic dysfunction and alcohol use may have changed since then.

DISCLOSURES:

The study was funded in part by the National Natural Science Foundation of China, the Taishan Scholar Program of Shandong Province, the Shandong Provincial Natural Science Foundation, the National Institutes of Health, and the NIH National Center for Advancing Translational Sciences UCLA Clinical and Translational Research Center. The authors declared no relevant conflicts of interest.

Women may gain greater health benefits from regular physical activity at equivalent or lower doses of activity, compared with men, according to data from more than 400,000 US adults. 

Over two decades, with any regular physical activity, all-cause mortality risk was reduced by 24% in women vs 15% in men, and cardiovascular mortality risk was reduced by 36% and 14%, respectively, compared with inactivity, researchers found. 

Participating in strength training exercises (vs not) was associated with a reduced risk for all-cause death of 19% in women and 11% men and reductions in cardiovascular death of 30% and 11%, respectively.

“Women have historically and statistically lagged behind men in engaging in meaningful exercise,” co–lead author Martha Gulati, MD, with the Smidt Heart Institute at Cedars-Sinai, Los Angeles, said in a statement. “The beauty of this study is learning that women can get more out of each minute of moderate to vigorous activity than men do. It’s an incentivizing notion that we hope women will take to heart.”

The study was published online February 19 in the Journal of the American College of Cardiology. 
 

Sex-Specific Exercise Advice? 

The findings are based on leisure-time physical activity data collected over roughly 20 years via the National Health Interview Survey for 412,413 US adults aged 27-61 years. During roughly 4.9 million person-years of follow-up, there were 39,935 all-cause deaths and 11,670 cardiovascular deaths.

Both men and women achieved a peak survival benefit at 300 minutes of weekly moderate to vigorous aerobic physical activity. But the mortality reduction was substantially greater in women than in men for the same amount of regular exercise (24% vs 18%). 

Similarly, for any given dose of physical activity leading up to 300 minutes per week, women derived proportionately greater survival benefits than did men, the authors reported. 

“Importantly, the greater magnitude of physical activity-related survival benefit in women than men was consistently found across varied measures and types of physical activity including frequency, duration per session, and intensity of aerobic physical activity, as well as frequency of muscle strengthening activities,” they wrote. 

They say multiple factors, including variations in anatomy and physiology, may account for the differences in outcomes between men and women. For example, compared with men, women may use more respiratory, metabolic, and strength demands to conduct the same movement and in turn, reap greater health benefits.

The study also showed only 33% of women and 43% of men regularly engaged in aerobic physical activity, whereas only 20% of women and 28% of men completed a weekly strength training session.

“We hope this study will help everyone, especially women, understand they are poised to gain tremendous benefits from exercise,” senior author Susan Cheng, MD, with the Smidt Heart Institute at Cedars-Sinai, Los Angeles, said in a statement.

In an accompanying editorial, Wael A. Jaber, MD, and Erika Hutt, MD, from Cleveland Clinic Ohio, wrote that this analysis “brings us one step farther in gaining insights into the role and influence of physiological responses to exercise with a sex-specific lens.” 

The study is “well designed and adds important information to the body of literature that can potentially close the gender gap and optimize sex-specific physical activity recommendations by policy makers and societal guidelines,” they wrote. 

“This study emphasizes that there is no singular approach for exercise. A person’s physical activity needs and goals may change based on their age, health status, and schedule — but the value of any type of exercise is irrefutable,” Eric J. Shiroma, ScD, with the National Heart, Lung, and Blood Institute, said in a statement. 

The study was supported in part by grants from the National Institutes of Health. The authors and editorial writers have declared no relevant conflicts of interest.
