The U.S. Preventive Services Task Force is planning to update its breast cancer screening guidelines, which were last issued in 2016. For transparency, it has released the draft research plan it will use for formulating the update, and this draft plan is open for comment until Feb. 17.

However, an expert in breast screening has taken issue with the whole plan.

Daniel Kopans, MD, professor of radiology at Harvard Medical School and founder of the Breast Imaging Division at Massachusetts General Hospital, Boston, argues that previous USPSTF guidelines on breast cancer screening “have been based on flawed analyses of scientific data” and the research plan, as outlined, perpetuates this.

He has also objected, yet again, to the USPSTF panel not having any experts in breast screening on the panel.

Writing in a commentary on Aunt Minnie, a radiology website, he warns about the dangers of not listening to experts: “The COVID-19 pandemic has demonstrated the tragic consequences that result from ignoring science, evidence, and the analysis and advice of experts while being guided by inexpert advice.”
 

Controversy over previous guidelines

The current USPSTF guidelines on breast cancer screening, which were issued in 2016, were largely unchanged from the previous guidelines that had been issued in 2009. They recommended mammography screening every 2 years for women 50-74 years of age but said that women aged 40-49 should make individual decisions about screening in partnership with their doctors.

The guidance on younger women was met with severe criticism from many experts, as previously reported by this news organization, and the every-2-year interval has also been questioned.

The American College of Radiology and Society of Breast Imaging both recommend annual mammograms starting at age 40.

In the update the USPSTF is now planning, it has an opportunity to “revisit the group’s flawed decision in 2009” about not recommending screening for women in their 40s, argues Dr. Kopans.  

But to do that, a number of factors need to be addressed to present a fair and impartial review of the science and evidence in favor of breast screening, he continues, while worrying the draft plan, as currently outlined, will not do so.

One big problem, he argues, is that USPSTF, in its draft plan, has not included statistical models from the U.S. National Cancer Institute and Cancer Intervention and Surveillance Modeling Network to project the potential outcomes of various screening protocols. These NCI/CISNET models all predict that the most lives are saved by annual screening starting at age 40, he points out.

Without these models, the USPSTF will be “guessing in their predictions,” he argues.

Second, even though a reduction in advanced-stage disease is a potentially useful “surrogate endpoint,” Dr. Kopans points out that it is still crucial to remember that women diagnosed at all stages of breast cancer die of the disease. “It has been shown that reducing the size of cancers within stages is also a major benefit from screening that reduces deaths,” he says.

Third, he contends in his commentary that there is a “false claim that the background incidence of breast cancer has not increased over time.” Dr. Kopans says this has been the primary source of misinformation that has been used to promote “the false concepts of massive overdiagnosis” as well as a “false claim that there has not been a reduction in advanced cancers.”

To emphasize his point, Dr. Kopans explains that data clearly demonstrate that the baseline incidence of breast cancer has steadily risen by 1%-1.3% per year, going back at least 80 years. This increase predates screening, which didn’t really begin until the mid-1980s.

“If the correct increasing baseline is used, not only is there no apparent ‘overdiagnosis’ of invasive cancers, but it appears that there has been a major reduction in the incidence of invasive cancers,” he writes. “By using the correct baseline incidence and extrapolation, it is also clear that there has been a major reduction in the rate of advanced cancers.”

To date, there have not been any randomized controlled trials comparing screening intervals (for example, annual vs. every second or third year). But based on the CISNET models, Dr. Kopans emphasized that annual screening is estimated to provide the greatest reduction in deaths. “All women ages 40-74 should be encouraged to be screened every year,” he says.

Exposure to antibiotics in mid- to late pregnancy was associated with childhood asthma in vaginally born children, in a Danish birth cohort study.

The reason behind the correlation is unclear. Maternal infections, rather than antibiotics, “could explain the observed association,” said study author Cecilie Skaarup Uldbjerg, a researcher in the department of public health at Aarhus University in Denmark.

Still, the “results are in keeping with the hypothesis that effects of antibiotics impact the maternally derived microbiome in vaginally born children and that this may increase the odds of childhood asthma,” Ms. Uldbjerg and coauthors wrote in their study, which was published online Feb. 9 in Archives of Disease in Childhood . “However, this observational study did not address underlying mechanisms, and this interpretation, while plausible, remains speculative.”
 

Antibiotic use in pregnancy likely to continue

Patrick Duff, MD, who was not involved in the research, does not expect the findings will alter clinical practice.

The association was relatively weak, and the study does not account for factors such as antibiotic exposure during early childhood or tobacco smoke in the house, said Dr. Duff, professor of maternal-fetal medicine at University of Florida, Gainesville.

“Although I agree that we should not use antibiotics indiscriminately during pregnancy, we definitely need to treat certain infections,” Dr. Duff said. “Thus we cannot avoid some degree of antibiotic exposure.”

Although prior research has indicated that antibiotic use in pregnancy may increase the risk of asthma in children, results have been inconsistent.

To study whether antibiotic exposure during pregnancy is associated with childhood asthma and whether the timing of antibiotic exposure or mode of delivery influence the relationship, the investigators analyzed data from more than 32,000 children in the Danish National Birth Cohort, which was established in 1996.
 

Children of mothers who took and did not take antibiotics compared

In all, 17% of the children were born to mothers who used antibiotics during pregnancy. Compared with mothers who did not take antibiotics, those who did reported more maternal asthma, smoking during pregnancy, and having overweight or obesity. In addition, they were less likely to have been in their first pregnancy.

During follow-up at age 11 years, 4,238 children (13%) had asthma, including 12.7% of those whose mothers had not been exposed to antibiotics, and 14.6% of those whose mothers had used antibiotics during pregnancy.

In adjusted analyses, children born to mothers who received antibiotics were more likely to have asthma (OR, 1.14).

Antibiotic exposure in the second to third trimester, but not in the first trimester, was associated with asthma. The association was observed in vaginally born children, but not in children born by cesarean section.

The study is limited by its reliance on maternal reporting for data about antibiotics and asthma diagnoses, the authors noted. Mothers completed telephone interviews twice during pregnancy and once at 6 months postpartum. They completed online questionnaires to provide follow-up information at 11 years.
 

Mode of delivery may matter

The researchers said their analysis indicates that mode of delivery may modify the association between antibiotic exposure during pregnancy and childhood asthma.

Fourteen percent of the children in the study were delivered by cesarean section. Further research may clarify the relationship between antibiotics in pregnancy, mode of delivery, and asthma risk, another doctor who was not involved the study added.

“I do not think that the evidence indicates that mode of delivery clearly has an impact,” said Santina J. G. Wheat, MD, MPH, associate professor of family and community medicine at Northwestern University in Chicago, “as the number of cesarean deliveries was not large enough to fully support such a statement.

“It will be interesting to see if an association holds in future studies with increased cesarean deliveries,” Dr. Wheat said.

How and why antibiotics were used may be other important factors to investigate, Dr. Duff suggested.

“The authors did not provide any specific information about which antibiotics were used by the mothers, duration of use, and indication for use. Those are very important confounders,” Dr. Duff said. “Perhaps the key exposure is to a particular maternal infection rather than to the antibiotic per se.”

The Danish National Birth Cohort was established with a grant from the Danish National Research Foundation and support from regional committees and other organizations. Its biobank has been supported by the Novo Nordisk Foundation and the Lundbeck Foundation, and follow-up of mothers and children has been supported by the Danish Medical Research Council, the Lundbeck Foundation, Innovation Fund Denmark, the Nordea Foundation, Aarhus Ideas, a University of Copenhagen strategic grant, and the Danish Council for Independent Research. The study was partially funded by the Health Research Fund of Central Denmark Region, which supported one of the authors. Other authors were supported by the DHB Foundation and the Australian National Health and Medical Research Council. One author is affiliated with Murdoch Children’s Research Institute in Australia, where the Victorian Government’s Operational Infrastructure Support Program supports research.

The authors had no competing interests. Dr. Wheat serves on the editorial advisory board of Family Practice News. Dr. Duff had no relevant financial disclosures.

Women with psoriasis can expect healthy pregnancy outcomes at a rate similar to that of the general population, according to one of the largest studies to examine the issue to date.

However, “pregnancy-specific registries that include a larger number of pregnant women with psoriasis ... are needed to more fully characterize the association between psoriasis and treatment and birth outcomes,” acknowledged first author Alexa B. Kimball, MD, MPH, professor of dermatology, Harvard Medical School, Boston, and colleagues.

The cohort study, published in JAMA Dermatology, used data from the Psoriasis Longitudinal Assessment and Registry (PSOLAR), which “is not a pregnancy specific registry, and medical history is captured only at baseline,” they noted.

Their findings showed pregnancy outcomes such as spontaneous abortion, neonatal problems, and congenital anomalies among women with moderate to severe psoriasis were similar to rates in the general U.S. population, and are “consistent with previously reported data,” they reported. “And pregnancy outcomes for women exposed to biologics were similar to those for women with exposure to nonbiologics.”

The study “provides further reassurance that the biologics appear safe at least related to pregnancy outcomes,” commented Jenny Murase, MD, associate professor of dermatology at the University of California, San Francisco, who was not involved in the study. In an interview, she noted that the study “did not examine any potential immunosuppression of the fetus in the first 6 months of life,” which she described as “the heart of the concern, more than whether or not the psoriasis or the biologic affects the pregnancy itself.”

The study used data from the PSOLAR registry collected from June 20, 2007, to Aug.23, 2019, which included 2,224 women of childbearing age (18-45 years) who were collectively followed up for 12,929 patient-years. Among these women, 220 had 298 pregnancies, with 244 live births (81.9%).

“Birth outcomes among all 244 births included 231 healthy newborns (94.7%), 10 infants with a neonatal problem (4.1%), 1 stillbirth (0.4%), and 2 congenital anomalies (0.8%),” the authors reported.

There were also 41 spontaneous abortions (13.8%), and 13 elective terminations (4.4%). “No elective terminations were known to derive from a congenital anomaly or other medical issue,” they added.

Among the documented pregnancies, 252 occurred in women with exposure to biologic therapy either before or during pregnancy, including 168 (56.4%) during the prenatal period, while 46 pregnancies occurred in women with no exposure to biologic therapy.

Dr. Murase, director of medical consultative dermatology for the Palo Alto Foundation Medical Group in Mountain View, Calif., said that a more detailed comparison of the different psoriasis treatments, as well as the offspring outcomes during the first 6 months of life, might offer some further important insight,.

Infants born after exposure to infliximab “and potentially other anti–tumor necrosis factor–alpha agents during the third trimester may be unable to develop an appropriate immune response to live vaccines,” she and her coauthors cautioned in a letter published in 2011, which referred to a case of an infant with disseminated bacillus Calmette-Guérin infection, whose mother had received infliximab for Crohn’s disease throughout pregnancy.

Dr. Murase pointed out that, in the registry study, exposures to certolizumab, which is pegylated and does not cross the placental barrier, were not separated from other cases. It is important to consider “the cross over late in the second trimester and especially third trimester as the infant is getting the ‘antibody boost’ from the mother as it gets ready to set foot in this world and needs the maternal antibodies to prepare its immune system. If the IgG biologics cross third trimester and immunosuppress the infant ... then I think a medication that does not cross the placental barrier is important to consider.”

The study was sponsored by Janssen Scientific Affairs. Dr. Kimball’s disclosures included serving as a consultant and investigator for companies that included AbbVie, Bristol-Myers Squibb, and Janssen; several other authors also had disclosures related to multiple pharmaceutical companies. Dr. Murase’s disclosures included serving as a consultant for Dermira, UCB Pharma, Sanofi, Ferndale, and Regeneron.

If the IgG biologics cross third trimester and immunosuppress the infant ... then I think a medication that does not cross the placental barrier is important to consider.”

The study was sponsored by Janssen Scientific Affairs. Dr. Kimball’s disclosures included serving as a consultant and investigator for companies that included AbbVie, Bristol-Myers Squibb, and Janssen; several other authors also had disclosures related to multiple pharmaceutical companies.

Women with psoriasis can expect healthy pregnancy outcomes at a rate similar to that of the general population, according to one of the largest studies to examine the issue to date.

However, “pregnancy-specific registries that include a larger number of pregnant women with psoriasis ... are needed to more fully characterize the association between psoriasis and treatment and birth outcomes,” acknowledged first author Alexa B. Kimball, MD, MPH, professor of dermatology, Harvard Medical School, Boston, and colleagues.

The cohort study, published in JAMA Dermatology, used data from the Psoriasis Longitudinal Assessment and Registry (PSOLAR), which “is not a pregnancy specific registry, and medical history is captured only at baseline,” they noted.

Their findings showed pregnancy outcomes such as spontaneous abortion, neonatal problems, and congenital anomalies among women with moderate to severe psoriasis were similar to rates in the general U.S. population, and are “consistent with previously reported data,” they reported. “And pregnancy outcomes for women exposed to biologics were similar to those for women with exposure to nonbiologics.”

The study “provides further reassurance that the biologics appear safe at least related to pregnancy outcomes,” commented Jenny Murase, MD, associate professor of dermatology at the University of California, San Francisco, who was not involved in the study. In an interview, she noted that the study “did not examine any potential immunosuppression of the fetus in the first 6 months of life,” which she described as “the heart of the concern, more than whether or not the psoriasis or the biologic affects the pregnancy itself.”

The study used data from the PSOLAR registry collected from June 20, 2007, to Aug.23, 2019, which included 2,224 women of childbearing age (18-45 years) who were collectively followed up for 12,929 patient-years. Among these women, 220 had 298 pregnancies, with 244 live births (81.9%).

“Birth outcomes among all 244 births included 231 healthy newborns (94.7%), 10 infants with a neonatal problem (4.1%), 1 stillbirth (0.4%), and 2 congenital anomalies (0.8%),” the authors reported.

There were also 41 spontaneous abortions (13.8%), and 13 elective terminations (4.4%). “No elective terminations were known to derive from a congenital anomaly or other medical issue,” they added.

Among the documented pregnancies, 252 occurred in women with exposure to biologic therapy either before or during pregnancy, including 168 (56.4%) during the prenatal period, while 46 pregnancies occurred in women with no exposure to biologic therapy.

Dr. Murase, director of medical consultative dermatology for the Palo Alto Foundation Medical Group in Mountain View, Calif., said that a more detailed comparison of the different psoriasis treatments, as well as the offspring outcomes during the first 6 months of life, might offer some further important insight,.

Infants born after exposure to infliximab “and potentially other anti–tumor necrosis factor–alpha agents during the third trimester may be unable to develop an appropriate immune response to live vaccines,” she and her coauthors cautioned in a letter published in 2011, which referred to a case of an infant with disseminated bacillus Calmette-Guérin infection, whose mother had received infliximab for Crohn’s disease throughout pregnancy.

Dr. Murase pointed out that, in the registry study, exposures to certolizumab, which is pegylated and does not cross the placental barrier, were not separated from other cases. It is important to consider “the cross over late in the second trimester and especially third trimester as the infant is getting the ‘antibody boost’ from the mother as it gets ready to set foot in this world and needs the maternal antibodies to prepare its immune system.

Menopause is a key time to monitor women for the development or increase of cardiovascular risk factors, according to a new consensus statement developed by the Task Force on Gender of the European Society of Cardiology and a multidisciplinary ESC working group on Women’s Health in Menopause.

“After menopause, traditional cardiovascular risk factors are adversely affected – particularly hypertension,” wrote Angela H.E.M. Maas, MD, of Radboud University Medical Center, Nijmegen, Netherlands, and colleagues.

“Since the first ESC consensus paper on the management of cardiovascular risk in perimenopausal women was published in 2007, we have a greater understanding on the role of female-specific risk factors for cardiovascular disease (CVD),” they said.

In a consensus statement published in the European Heart Journal, the authors presented clinical guidance for diagnosis and management of cardiovascular risk factors during the menopause transition. The transition to menopause increases a woman’s risk for developing several CVD risk factors, including central adiposity, increased insulin resistance, a proatherogenic lipid profile, and autonomic dysfunction that can contribute to increased heart rate variability, according to the statement.

Estrogen changes may affect ischemic disease

In general, obstructive coronary artery disease (CAD) strikes women later than men, but coronary vasomotor conditions are a common cause of ischemic heart disease in women with or without CAD, the authors noted.

“Lower estrogen levels after menopause are related to altered vascular function, enhanced inflammation, and up-regulation of other hormonal systems such as the renin–angiotensin–aldosterone system, the sympathetic nervous system, and reduced nitric oxide–dependent vasodilation,” they wrote. They recommended use of the coronary artery calcium score for screening middle-aged women who are symptomatic or at intermediate cardiovascular risk.

The transition to menopause causes changes in lipid profiles, and a rise in blood pressure in particular “may be both a direct effect of hormonal changes on the vasculature and metabolic changes with aging,” but hypertension in early post menopause is “often poorly managed,” the authors noted.

Compared with asymptomatic women, women who suffer from severe menopausal symptoms often have increased cardiovascular disease risk factors. For example, the Women’s Health Initiative (WHI) study showed a 48% increased risk of incident diabetes at follow-up in women with severe symptoms of hot flashes and night sweats, the authors wrote. Clinicians should also be aware of the increased immune reactivity that occurs during and after menopause and the increased CVD risk associated with autoimmune and endocrine disorders, they said.
 

Multiple strategies to reduce risk

Strategies to address the cardiovascular risk in menopause include assessing glucose, lipid levels, and blood pressure during the transition to menopause, according to the statement.

In addition, they recommended increasing employer awareness of menopause, as changes may interfere with working ability. A healthy lifestyle including healthy diet and regular exercise can help reduce cardiovascular risks and relieve symptoms. Menopausal hormone therapy (MHT) may be indicated to relieve symptoms, including symptoms of depression, and provide cardioprotection for younger women around the time of menopause, according to the statement.

However, “MHT is not recommended in women at high CV risk and after a previous CVD event,” and all women should be assessed for cardiovascular risk factors before starting MHT, they emphasized.
 

Results raise awareness of cardiovascular health and menopause link

“Over the past 20 years, our knowledge of how menopause might contribute to cardiovascular disease has dramatically evolved,” said Samar El Khoudary, MD, of the University of Pittsburg, in an interview.

“We have accumulated data that consistently point to the menopause transition as a time of change in cardiovascular health. As such, there is a compelling need to discuss the implications of the accumulating body of literature on this topic,” she said. “The goal is to raise awareness for both health care providers and women of the significant adverse cardiovascular health changes accompanying the menopause transition and to point out the importance of adopting prevention strategies early during this stage,” she explained.

The impact of the hormonal changes of menopause on CVD risk “is very complex,” Dr. El Khoudary said. “Until now, we could not prove that using estrogen therapy is cardioprotective,” she emphasized. “Studies point to the need to consider the timing of hormone use, as well as types and route of administration,” she noted. “The truth is that, although the menopause transition is associated with an acceleration in CVD risk, the exact mechanism still is not completely clear. Hormone changes contribute, but they are not the ultimate contributor,” she added.

 

Research gaps include data on lifestyle and behavioral interventions

“Irrespective of the accumulating findings showing adverse changes in multiple cardiovascular health parameters, as women transition through menopause, we do not have data documenting current status of ideal cardiovascular health components during the menopause transition among women,” said Dr. El Khoudary. “The limited data we have [suggest] that a very small proportion of women transitioning through menopause eat a healthy diet (less than 20%) or practice physical activity (about7.2%) at a level that matches the current recommendations,” she noted.

“Lifestyle and behavioral interventions are critical to maintain a healthy heart and reduce heart disease; we do not have adequate randomized clinical trials testing these interventions specifically during the menopause transition,” she said.

“Similarly, we are in need of randomized clinical trials of therapeutic interventions such as lipid-lowering medications and menopause hormone therapy in women transitioning through menopause,” said Dr. El Khoudary. “This high-risk population has not been the focus of previous clinical trials, leaving us with questions of how the results from these studies might apply to women during the menopause transition,” she said.
 

Consensus invites collaboration

“I commend the group for putting together a statement that crosses practice and specialty boundaries,” said Lubna Pal, MD, of Yale School of Medicine, New Haven, Conn., in an interview. Although the statement does not present novel information, it “has the power of unifying the various providers by bringing focus on the individual elements spanning a woman’s life that cumulatively determine her lifetime health risk,” she said. Preeclampsia may be a risk factor for cardiovascular disease later in life, and events in reproductive age may determine a woman’s trajectory during the transition to menopause and beyond, Dr. Pal noted.

“The consensus statement will likely be read by internists and family medicine providers as well as ob.gyns.; it encourages all those involved in caring for female patients to take on the responsibility of ‘passing on the baton,’ such that all women who are deemed at an enhanced risk for cardiovascular disease are assured due diligence in care through stringent surveillance and timely interventions,” said Dr. Pal. “It is a call for the various providers who care for women at distinct stages of life to work together toward a shared goal of optimizing every woman’s health across her lifespan,” she said.

“More research is needed for us to better understand the mechanisms at play” in the development of cardiovascular risk and in understanding the continuity of changes across women’s lifespans, Dr. Pal said. “We have associations, but not much information about causation,” she emphasized. However, the statement promotes the dissemination of information about women’s health and sensitizes providers to the potential and the power of preventive care. “We should be much more liberal and loud in holding conversations about risk quantification and risk reduction, and this statement is a resounding effort toward identifying and mitigating long-term cardiovascular risk, even if only through promoting a healthier lifestyle in those deemed at risk,” she added.  

The statement received no outside funding. Lead author Dr. Maas had no financial conflicts to disclose. Dr. El Khoudary had no financial conflicts to disclose. Dr. Pal had no relevant financial conflicts to disclose.

Use of prophylactic negative pressure wound therapy may not be appropriate in surgical cases where women undergo a laparotomy for presumed gynecologic malignancy, according to recent research published in Obstetrics & Gynecology.

“The results of our randomized trial do not support the routine use of prophylactic negative pressure wound therapy at the time of laparotomy incision closure in women who are undergoing surgery for gynecologic malignancies or in morbidly obese women who are undergoing laparotomy for benign indications,” wrote Mario M. Leitao Jr., MD, of Memorial Sloan Kettering Cancer Center in New York, and colleagues.

Dr. Leitao and colleagues randomized 663 patients, stratified by body mass index after skin closure, to receive negative pressure wound therapy (NPWT) or standard gauze after undergoing a laparotomy for gynecologic surgery between March 2016 and August 2019.

The median age of the patients was 61 years and median BMI was 26 kg/m². Thirty-two patients with a BMI of 40 kg/m² or higher who underwent a laparotomy for gynecologic surgery regardless of indication were also included in the study. Most women (80%-82%) were undergoing surgery to treat ovary, fallopian tube, or peritoneal cancer. The most common medical comorbidities in both groups were hypertension (34%-35%) and diabetes (8%-14%). Information on race of patients was not included in the baseline characteristics for the study.

In total, 505 patients were available for evaluation after surgery, which consisted of 254 patients in the NPWT group and 251 patients in the standard gauze group, with 495 patients (98%) having a malignant indication. The researchers examined the incidence of wound complication up to 30 days after surgery.

The results showed a similar rate of wound complications in the NPWT group (44 patients; 17.3%) compared with the group receiving standard gauze (41 patients; 16.3%), with an absolute risk difference between groups of 1% (90% confidence interval, –4.5-6.5%; P = .77). Nearly all patients who developed wound complications in both NPWT (92%) and standard gauze (95%) groups had the wound complication diagnosis occur after discharge from the hospital. Dr. Leitao and colleagues noted similarities between groups with regard to wound complications, with most patients having grade 1 complications, and said there were no instances of patients requiring surgery for complications. Among patients in the NPWT group, 33 patients developed skin blistering compared with 3 patients in the standard gauze group (13% vs. 1.2%; P < .001). After an interim analysis consisting of 444 patients, the study was halted because of “low probability of showing a difference between the two groups at the end of the study.”

The analysis of patients with a BMI of 40 kg/m² or higher showed 7 of 15 patients (47%) developed wound complications in the NPWT group and 6 of 17 patients (35%) did so in the standard gauze group (P = .51). In post hoc analyses, the researchers found a median BMI of 26 kg/m² (range, 17-60 kg/m²) was significantly associated with not developing a wound complication compared with a BMI of 32 kg/m² (range, 17-56 kg/m²) (P < .001), and that 41% of patients with a BMI of at least 40 kg/m² experienced wound complications compared with 15% of patients with a BMI of less than 40 kg/m² (P < .001). There was an independent association between developing a wound complication and increasing BMI, according to a multivariate analysis (adjusted odds ratio, 1.10; 95% confidence interval, 1.06–1.14).
 

Applicability of results unclear for patients with higher BMI

Sarah M. Temkin, MD, a gynecologic oncologist who was not involved with the study, said in an interview that the results by Leitao and colleagues answer the question of whether patients undergoing surgery for gynecologic malignancy require NPWT, but raised questions about patient selection in the study.

“I think it’s hard to take data from this type of high-end surgical practice and apply it to the general population,” she said, noting the median BMI of 26 kg/m² for patients included in the study. A study that included only patients with a BMI of 40 kg/m² or higher “would have made these results more applicable,” she said.

The low rate of wound complications in the study could be explained by patient selection, Dr. Temkin explained. She cited her own retrospective study from 2016 that showed a wound complication rate of 27.3% for patients receiving prophylactic NPWT where the BMI for the group was 41.29 kg/m² compared with a complication rate of 19.7% for patients receiving standard care who had a BMI of 30.67 kg/m².

“It’s hard to cross trial compare, but that’s significantly higher than what they saw in this prospective study, and I would say that’s a difference with the patient population,” she said. “I think the question of how to reduce surgical site infections and wound complications in the heavy patient with comorbidities is still unanswered.”

The question is important because patients with a higher BMI and medical comorbidities “still need cancer surgery and methods to reduce the morbidity of that surgery,” Dr. Temkin said. “I think this is an unmet need.”

This study was funded in part by a support grant from NIH/NCI Cancer Center, and KCI/Acelity provided part of the study protocol. Nine authors reported personal and institutional relationships in the form of personal fees, grants, stock ownership, consultancies, and speakers bureau positions with AstraZeneca, Biom’Up, Bovie Medical Co., C Surgeries, CMR, ConMed, Covidien, Ethicon, GlaxoSmithKline, GRAIL, Intuitive Surgical Inc., JNJ, Medtronic, Merck, Mylan, Olympus, Stryker/Novadaq, TransEnterix Inc., UpToDate, and Verthermia Inc.

The analysis of patients with a BMI of 40 kg/m² or higher showed 7 of 15 patients (47%) developed wound complications in the NPWT group and 6 of 17 patients (35%) did so in the standard gauze group (P = .51). In post hoc analyses, the researchers found a median BMI of 26 kg/m² (range, 17-60 kg/m²) was significantly associated with not developing a wound complication compared with a BMI of 32 kg/m² (range, 17-56 kg/m²) (P < .001), and that 41% of patients with a BMI of at least 40 kg/m² experienced wound complications compared with 15% of patients with a BMI of less than 40 kg/m² (P < .001). There was an independent association between developing a wound complication and increasing BMI, according to a multivariate analysis (adjusted odds ratio, 1.10; 95% confidence interval, 1.06–1.14).
 

Applicability of results unclear for patients with higher BMI

Sarah M. Temkin, MD, a gynecologic oncologist who was not involved with the study, said in an interview that the results by Leitao and colleagues answer the question of whether patients undergoing surgery for gynecologic malignancy require NPWT, but raised questions about patient selection in the study.

“I think it’s hard to take data from this type of high-end surgical practice and apply it to the general population,” she said, noting the median BMI of 26 kg/m² for patients included in the study. A study that included only patients with a BMI of 40 kg/m² or higher “would have made these results more applicable,” she said.

The low rate of wound complications in the study could be explained by patient selection, Dr. Temkin explained. She cited her own retrospective study from 2016 that showed a wound complication rate of 27.3% for patients receiving prophylactic NPWT where the BMI for the group was 41.29 kg/m² compared with a complication rate of 19.7% for patients receiving standard care who had a BMI of 30.67 kg/m².

“It’s hard to cross trial compare, but that’s significantly higher than what they saw in this prospective study, and I would say that’s a difference with the patient population,” she said. “I think the question of how to reduce surgical site infections and wound complications in the heavy patient with comorbidities is still unanswered.”

The question is important because patients with a higher BMI and medical comorbidities “still need cancer surgery and methods to reduce the morbidity of that surgery,” Dr. Temkin said. “I think this is an unmet need.”

This study was funded in part by a support grant from NIH/NCI Cancer Center, and KCI/Acelity provided part of the study protocol.

Use of prophylactic negative pressure wound therapy may not be appropriate in surgical cases where women undergo a laparotomy for presumed gynecologic malignancy, according to recent research published in Obstetrics & Gynecology.

“The results of our randomized trial do not support the routine use of prophylactic negative pressure wound therapy at the time of laparotomy incision closure in women who are undergoing surgery for gynecologic malignancies or in morbidly obese women who are undergoing laparotomy for benign indications,” wrote Mario M. Leitao Jr., MD, of Memorial Sloan Kettering Cancer Center in New York, and colleagues.

Dr. Leitao and colleagues randomized 663 patients, stratified by body mass index after skin closure, to receive negative pressure wound therapy (NPWT) or standard gauze after undergoing a laparotomy for gynecologic surgery between March 2016 and August 2019.

The median age of the patients was 61 years and median BMI was 26 kg/m². Thirty-two patients with a BMI of 40 kg/m² or higher who underwent a laparotomy for gynecologic surgery regardless of indication were also included in the study. Most women (80%-82%) were undergoing surgery to treat ovary, fallopian tube, or peritoneal cancer. The most common medical comorbidities in both groups were hypertension (34%-35%) and diabetes (8%-14%). Information on race of patients was not included in the baseline characteristics for the study.

In total, 505 patients were available for evaluation after surgery, which consisted of 254 patients in the NPWT group and 251 patients in the standard gauze group, with 495 patients (98%) having a malignant indication. The researchers examined the incidence of wound complication up to 30 days after surgery.

The results showed a similar rate of wound complications in the NPWT group (44 patients; 17.3%) compared with the group receiving standard gauze (41 patients; 16.3%), with an absolute risk difference between groups of 1% (90% confidence interval, –4.5-6.5%; P = .77). Nearly all patients who developed wound complications in both NPWT (92%) and standard gauze (95%) groups had the wound complication diagnosis occur after discharge from the hospital. Dr. Leitao and colleagues noted similarities between groups with regard to wound complications, with most patients having grade 1 complications, and said there were no instances of patients requiring surgery for complications. Among patients in the NPWT group, 33 patients developed skin blistering compared with 3 patients in the standard gauze group (13% vs. 1.2%; P < .001). After an interim analysis consisting of 444 patients, the study was halted because of “low probability of showing a difference between the two groups at the end of the study.”

There are some differences in how women relative to men report symptoms of an acute coronary syndrome (ACS), but they should not be permitted to get in the way of prompt diagnosis and treatment, according to an expert review at the virtual Going Back to the Heart of Cardiology meeting.

“We need to get away from the idea that symptoms of a myocardial infarction in women are atypical, because women are also having typical symptoms,” said Martha Gulati, MD, chief of cardiology at the University of Arizona, Phoenix.
 

Sexes share key symptoms, but not treatment

Although “women are more likely to report additional symptoms,” chest pain “is pretty much equal between men and women” presenting with an ACS, according to Dr. Gulati.

There are several studies that have shown this, including the Variation in Recovery: Role of Gender on Outcomes of Young AMI patients (VIRGO). In VIRGO, which looked at ACS symptom presentation in younger patients (ages 18-55 years), 87.0% of women versus 89.5% of men presented with chest pain defined as pain, pressure, tightness, or discomfort.

Even among those who recognize that more women die of cardiovascular disease (CVD) disease than any other cause, nothing seems to erase the bias that women in an ED are less likely than men to be having a heart attack. About 60 million women in the United States have CVD, so no threat imposes a higher toll in morbidity and mortality.

In comparison, there are only about 3.5 million women with breast cancer. Even though this is a major cause of morbidity and mortality in women, it is dwarfed by CVD, according to statistics cited by Dr. Gulati. Yet, the data show women get inferior care by guideline-based standards.

“After a myocardial infarction, women relative to men are less likely to get aspirin or beta-blockers within 24 hours, they are less likely to undergo any type of invasive procedure, and they are less likely to meet the door-to-balloon time or receive any reperfusion therapy,” Dr. Gulati said. After a CVD event, “the only thing women do better is to die.”
 

Additional symptoms may muddy the diagnostic waters

In the setting of ACS, the problem is not that women fail to report symptoms that should lead clinicians to consider CVD, but that they report additional symptoms. For the clinician less inclined to consider CVD in women, particularly younger women, there is a greater risk of going down the wrong diagnostic pathway.

In other words, women report symptoms consistent with CVD, “but it is a question of whether we are hearing it,” Dr. Gulati said.

In the VIRGO study, 61.9% of women versus 54.8% of men (P < .001) presented three or more symptoms in addition to chest pain, such as epigastric symptoms, discomfort in the arms or neck, or palpitations. Women were more likely than men to attribute the symptoms to stress or anxiety (20.9% vs. 11.8%; P < .001), while less likely to consider them a result of muscle pain (15.4% vs. 21.2%; P = .029).

There are other gender differences for ACS. For example, women are more likely than men to presented ischemia without obstruction, but Dr. Gulati emphasized that lack of obstruction is not a reason to dismiss the potential for an underlying CV cause.
 

‘Yentl syndrome’ persists

“Women should not need to present exactly like men to be taken seriously,” she said, describing the “Yentl syndrome,” which now has its own Wikipedia page. A cardiovascular version of this syndrome was first described 30 years ago. Based on a movie of a woman who cross dresses in order to be allowed to undertake Jewish studies, the term captures the societal failure to adapt care for women who do not present disease the same way that men do.

Overall, inadequate urgency to pursue potential symptoms of ACS in women is just another manifestation of the “bikini approach to women’s health,” according to Dr. Gulati. This describes the focus on the breast and reproductive system to the exclusion or other organs and anatomy. Dr. Gulati speculated that this might be the reason that clinicians have failed to apply ACS guidelines to women with the same rigor that they apply to men.

This is hardly a new issue. Calls for improving cardiovascular care in women have been increasing in volume for more than past 20 years, but the issue has proven persistent, according to Dr. Gulati. As an example, she noted that the same types of gaps in care and in outcome reported in a 2008 registry study had not much changed in an article published 8 years later.

The solution is not complex, according to Dr. Gulati. In the ED, guideline-directed diagnostic tests should be offered to any man or woman, including younger women, who present with chest pain, ignoring gender bias that threatens misinterpretation of patient history and symptoms. Once CVD is diagnosed as promptly in women as it is in men, guideline-directed intervention would be expected to reduce the gender gap in outcomes.

“By applying standardized protocols, it will help us to the same for women as we do for men,” Dr. Gulati said.

A new approach to breast screening proposes that all women should have a baseline evaluation of breast density by mammography at the age of 40.

The result would then be used to stratify further screening, with annual screening starting at age 40 for average-risk women who have dense breasts, and screening every 2 years starting at age 50 for women without dense breasts.

Such an approach would be cost effective and offers a more targeted risk-based strategy for the early detection of breast cancer when compared with current practices, say the authors, led by Tina Shih, PhD, University of Texas MD Anderson Cancer Center, Houston.

Their modeling study was published online in the Annals of Internal Medicine.

However, experts writing in an accompanying editorial are not persuaded. Karla Kerlikowske, MD, and Kirsten Bibbins-Domingo, MD, PhD, both from the University of California, San Francisco, point out that not all women with dense breasts are at increased risk for breast cancer. They caution against relying on breast density alone when determining screening strategies, and say age and other risk factors also need to be considered.
 

New approach proposed

Current recommendations from the United States Preventive Services Task Force suggest that women in their 40s can choose to undergo screening mammography based on their own personal preference, Dr. Shih explained in an interview.

However, these recommendations do not take into consideration the additional risk that breast density confers on breast cancer risk – and the only way women can know their breast density is to have a mammogram. “If you follow [current] guidelines, you would not know about your breast density until the age of 45 or 50,” she commented.

“But what if you knew about breast density earlier on and then acted on it –would that make a difference?” This was the question her team set out to explore.

For their study, the authors defined women with dense breasts as those with the Breast Imaging Reporting and Data System (BI-RADS) category C (heterogeneously dense breasts) and category D (extremely dense breasts).

The team used a computer model to compare seven different breast screening strategies:

• No screening.
• Triennial mammography from age 50 to 75 years (T50).
• Biennial mammography from age 50 to 75 years (B50).
• Stratified annual mammography from age 50 to 75 for women with dense breasts at age 50, and triennial. screening from age 50 to 75 for women without dense breasts at the age of 50 (SA50T50).
• Stratified annual mammography from age 50 to 75 for women with dense breasts at age 50, and biennial screening from age 50 to 75 for those without dense breast at age 50 (SA50B50).
• Stratified annual mammography from age 40 to 75 for women with dense breasts at age 49, and triennial screening from age 50 to 75 for those without dense breasts at age 40 (SA40T50).
• Stratified annual mammography from age 40 to 75 for women with dense breasts at age 40, and biennial mammography for women from age 50 to 75 without dense breasts at age 40 (SA40B50).

Compared with a no-screening strategy, the average number of mammography sessions through a woman’s lifetime would increase from seven mammograms per lifetime for the least frequent screening (T50) to 22 mammograms per lifetime for the most intensive screening schedule, the team reports.  

Compared with no screening, screening would reduce breast cancer deaths by 8.6 per 1,000 women (T50)–13.2 per 1,000 women (SA40B50).

A cost-effectiveness analysis showed that the proposed new approach (SA40B50) yielded an incremental cost-effectiveness ratio of $36,200 per quality-adjusted life-year (QALY), compared with the currently recommended biennial screening strategy. This is well within the willingness-to-pay threshold of $100,000 per QALY that is generally accepted by society, the authors point out.

On the other hand, false-positive results and overdiagnosis would increase, the authors note.

The average number of false positives would increase from 141.2 per 1,000 women who underwent the least frequent triennial mammography screening schedule (T50) to 567.3 per 1,000 women with the new approach (SA40B50).  

Rates of overdiagnosis would also increase from a low of 12.5% to a high of 18.6%, they add.

“With this study, we are not saying that everybody should start screening at the age of 40. We’re just saying, do a baseline mammography at 40, know your breast density status, and then we can try to modify the screening schedule based on individual risk,” Dr. Shih emphasized.

“Compared with other screening strategies examined in our study, this strategy is associated with the greatest reduction in breast cancer mortality and is cost effective, [although it] involves the most screening mammograms in a woman’s lifetime and higher rates of false-positive results and overdiagnosis,” the authors conclude.  
 

Fundamental problem with this approach 

The fundamental problem with this approach of stratifying risk on measurement of breast density – and on the basis of a single reading – is that not every woman with dense breasts is at increased risk for breast cancer, the editorialists comment.

Dr. Kerlikowske and Dr. Bibbins-Domingo point out that, in fact, only about one-quarter of women with dense breasts are at high risk for a missed invasive cancer within 1 year of a negative mammogram, and these women can be identified by using the Breast Cancer Surveillance Consortium risk model.

“This observation means that most women with dense breasts can undergo biennial screening and need not consider annual screening or supplemental imaging,” the editorialists write.

“Thus, we caution against using breast density alone to determine if a woman is at elevated risk for breast cancer,” they emphasize.

An alternative option is to focus on overall risk to select screening strategies, they suggest. For example, most guidelines recommend screening from age 50 to 74, so identifying women in their 40s who have the same risk of a woman aged 50-59 is one way to determine who may benefit from earlier initiation of screening, the editorialists observe.

“Thus, women who have a first-degree relative with breast cancer or a history of breast biopsy could be offered screening in their 40s, and, if mammography shows dense breasts, they could continue biennial screening through their 40s,” the editorialists observe. “Such women with nondense breasts could resume biennial screening at age 50 years.”  

Dr. Shih told this news organization that she did not disagree with the editorialists’ suggestion that physicians could focus on overall breast cancer risk to select an appropriate screening strategy for individual patients.

“What we are suggesting is, ‘Let’s just do a baseline assessment at the age of 40 so women know their breast density instead of waiting until they are older,’ “ she said.

“But what the editorialists are suggesting is a strategy that could be even more cost effective,” she acknowledged. Dr. Shih also said that Dr. Kerlikowske and Dr. Bibbins-Domingo’s estimate that only one-quarter of women with dense breasts are actually at high risk for breast cancer likely reflects their limitation of breast density to only those women with BI-RADs category “D” – extremely dense breasts.

Yet as Dr. Shih notes, women with category C and category D breast densities are both at higher risk for breast cancer, so ignoring women with lesser degrees of breast density still doesn’t address the fact that they have a higher-than-average risk for breast cancer.

“It’s getting harder to make universal screening strategies work as we are learning more and more about breast cancer, so people are starting to talk about screening strategies based on a patient’s risk classification,” Dr. Shih noted.

“It’ll be harder to implement these kinds of strategies, but it seems like the right way to go,” she added.

The study was funded by the National Cancer Institute. Dr. Shih reports grants from the National Cancer Institute during the conduct of the study and personal fees from Pfizer and AstraZeneca outside the submitted work. Dr. Kerlikowske is an unpaid consultant for GRAIL for the STRIVE study. Dr. Bibbins-Domingo has disclosed no relevant financial relationships.

For their study, the authors defined women with dense breasts as those with the Breast Imaging Reporting and Data System (BI-RADS) category C (heterogeneously dense breasts) and category D (extremely dense breasts).

The team used a computer model to compare seven different breast screening strategies:

• No screening.
• Triennial mammography from age 50 to 75 years (T50).
• Biennial mammography from age 50 to 75 years (B50).
• Stratified annual mammography from age 50 to 75 for women with dense breasts at age 50, and triennial. screening from age 50 to 75 for women without dense breasts at the age of 50 (SA50T50).
• Stratified annual mammography from age 50 to 75 for women with dense breasts at age 50, and biennial screening from age 50 to 75 for those without dense breast at age 50 (SA50B50).
• Stratified annual mammography from age 40 to 75 for women with dense breasts at age 49, and triennial screening from age 50 to 75 for those without dense breasts at age 40 (SA40T50).
• Stratified annual mammography from age 40 to 75 for women with dense breasts at age 40, and biennial mammography for women from age 50 to 75 without dense breasts at age 40 (SA40B50).

Compared with a no-screening strategy, the average number of mammography sessions through a woman’s lifetime would increase from seven mammograms per lifetime for the least frequent screening (T50) to 22 mammograms per lifetime for the most intensive screening schedule, the team reports.  

Compared with no screening, screening would reduce breast cancer deaths by 8.6 per 1,000 women (T50)–13.2 per 1,000 women (SA40B50).

A cost-effectiveness analysis showed that the proposed new approach (SA40B50) yielded an incremental cost-effectiveness ratio of $36,200 per quality-adjusted life-year (QALY), compared with the currently recommended biennial screening strategy. This is well within the willingness-to-pay threshold of $100,000 per QALY that is generally accepted by society, the authors point out.

On the other hand, false-positive results and overdiagnosis would increase, the authors note.

The average number of false positives would increase from 141.2 per 1,000 women who underwent the least frequent triennial mammography screening schedule (T50) to 567.3 per 1,000 women with the new approach (SA40B50).  

Rates of overdiagnosis would also increase from a low of 12.5% to a high of 18.6%, they add.

“With this study, we are not saying that everybody should start screening at the age of 40. We’re just saying, do a baseline mammography at 40, know your breast density status, and then we can try to modify the screening schedule based on individual risk,” Dr. Shih emphasized.

“Compared with other screening strategies examined in our study, this strategy is associated with the greatest reduction in breast cancer mortality and is cost effective, [although it] involves the most screening mammograms in a woman’s lifetime and higher rates of false-positive results and overdiagnosis,” the authors conclude.  
 

Fundamental problem with this approach 

The fundamental problem with this approach of stratifying risk on measurement of breast density – and on the basis of a single reading – is that not every woman with dense breasts is at increased risk for breast cancer, the editorialists comment.

Dr. Kerlikowske and Dr. Bibbins-Domingo point out that, in fact, only about one-quarter of women with dense breasts are at high risk for a missed invasive cancer within 1 year of a negative mammogram, and these women can be identified by using the Breast Cancer Surveillance Consortium risk model.

“This observation means that most women with dense breasts can undergo biennial screening and need not consider annual screening or supplemental imaging,” the editorialists write.

“Thus, we caution against using breast density alone to determine if a woman is at elevated risk for breast cancer,” they emphasize.

An alternative option is to focus on overall risk to select screening strategies, they suggest. For example, most guidelines recommend screening from age 50 to 74, so identifying women in their 40s who have the same risk of a woman aged 50-59 is one way to determine who may benefit from earlier initiation of screening, the editorialists observe.

“Thus, women who have a first-degree relative with breast cancer or a history of breast biopsy could be offered screening in their 40s, and, if mammography shows dense breasts, they could continue biennial screening through their 40s,” the editorialists observe. “Such women with nondense breasts could resume biennial screening at age 50 years.”  

Dr. Shih told this news organization that she did not disagree with the editorialists’ suggestion that physicians could focus on overall breast cancer risk to select an appropriate screening strategy for individual patients.

“What we are suggesting is, ‘Let’s just do a baseline assessment at the age of 40 so women know their breast density instead of waiting until they are older,’ “ she said.

“But what the editorialists are suggesting is a strategy that could be even more cost effective,” she acknowledged. Dr. Shih also said that Dr. Kerlikowske and Dr. Bibbins-Domingo’s estimate that only one-quarter of women with dense breasts are actually at high risk for breast cancer likely reflects their limitation of breast density to only those women with BI-RADs category “D” – extremely dense breasts.

Yet as Dr. Shih notes, women with category C and category D breast densities are both at higher risk for breast cancer, so ignoring women with lesser degrees of breast density still doesn’t address the fact that they have a higher-than-average risk for breast cancer.

“It’s getting harder to make universal screening strategies work as we are learning more and more about breast cancer, so people are starting to talk about screening strategies based on a patient’s risk classification,” Dr. Shih noted.

“It’ll be harder to implement these kinds of strategies, but it seems like the right way to go,” she added.

The study was funded by the National Cancer Institute. Dr. Shih reports grants from the National Cancer Institute during the conduct of the study and personal fees from Pfizer and AstraZeneca outside the submitted work. Dr. Kerlikowske is an unpaid consultant for GRAIL for the STRIVE study. Dr. Bibbins-Domingo has disclosed no relevant financial relationships.

A new approach to breast screening proposes that all women should have a baseline evaluation of breast density by mammography at the age of 40.

The result would then be used to stratify further screening, with annual screening starting at age 40 for average-risk women who have dense breasts, and screening every 2 years starting at age 50 for women without dense breasts.

Such an approach would be cost effective and offers a more targeted risk-based strategy for the early detection of breast cancer when compared with current practices, say the authors, led by Tina Shih, PhD, University of Texas MD Anderson Cancer Center, Houston.

Their modeling study was published online in the Annals of Internal Medicine.

However, experts writing in an accompanying editorial are not persuaded. Karla Kerlikowske, MD, and Kirsten Bibbins-Domingo, MD, PhD, both from the University of California, San Francisco, point out that not all women with dense breasts are at increased risk for breast cancer. They caution against relying on breast density alone when determining screening strategies, and say age and other risk factors also need to be considered.
 

New approach proposed

Current recommendations from the United States Preventive Services Task Force suggest that women in their 40s can choose to undergo screening mammography based on their own personal preference, Dr. Shih explained in an interview.

However, these recommendations do not take into consideration the additional risk that breast density confers on breast cancer risk – and the only way women can know their breast density is to have a mammogram. “If you follow [current] guidelines, you would not know about your breast density until the age of 45 or 50,” she commented.

“But what if you knew about breast density earlier on and then acted on it –would that make a difference?” This was the question her team set out to explore.

• Stratified annual mammography from age 50 to 75 for women with dense breasts at age 50, and biennial screening from age 50 to 75 for those without dense breast at age 50 (SA50B50).
• Stratified annual mammography from age 40 to 75 for women with dense breasts at age 49, and triennial screening from age 50 to 75 for those without dense breasts at age 40 (SA40T50).
• Stratified annual mammography from age 40 to 75 for women with dense breasts at age 40, and biennial mammography for women from age 50 to 75 without dense breasts at age 40 (SA40B50).

The more complaints of excessive force by police reported by neighborhood residents, the more likely it is that Black pregnant people living in that neighborhood will deliver preterm, according to findings from a new study presented Jan. 28 at the virtual Society for Maternal-Fetal Medicine 2021 Annual Pregnancy Meeting.

“We know there are significant racial disparities in preterm birth which aren’t fully explained by traditional risk factors, like being older, having health problems like high blood pressure, or limited income,” Alexa Freedman, PhD, a postdoctoral fellow at NorthShore University HealthSystem and Northwestern University Institute for Policy Research, Evanston, Ill., told this news organization. “This has left many wondering if there are stressors unique to Black individuals that may be involved,” which has led to past research on the association of preterm birth with neighborhood segregation and historical “redlining” practices.

Black individuals have a substantially higher rate of preterm birth, compared with all other racial and ethnic groups in the US: 13.8% of Black infants born between 2016 and 2018 were preterm, compared with 11.6% among Native Americans – the next highest group – and 9.1% among White women.

“Studies have shown that psychosocial stress contributes to preterm birth disparities, potentially through several physiologic pathways that impact pregnancy outcomes,” Dr. Freedman told attendees. “Pregnant Black individuals have been reported to experience greater psychosocial stress regardless of socioeconomic status, possibly secondary to experiences of racism and discrimination.”

Though past research has examined neighborhood disadvantage and violence as stressors potentially contributing to preterm birth, little data exist on police–community relationships or police violence and pregnancy outcomes, despite being a “particularly salient stressor for Black individuals,” Dr. Freedman said. “Among pregnant Black individuals, prenatal depression has been correlated with concern about negative interactions between youth in their community and police.” To cite one example of the prevalence of racial bias in policing, she noted that “Chicago police are almost 10 times more likely to use force when interacting with a Black individual as compared [with] a White individual.”

The researchers therefore sought to determine whether a relationship existed between preterm birth rates and complaints regarding use of excessive force by police in the same neighborhood. They compiled records on all singleton live births from one Chicago hospital between March 2008 and March 2018, excluding those who lived outside Chicago, had a missing address, listed their race as “other,” or lacked data for specific other confounders.
 

Assessing police complaints within census blocks

The researchers obtained data on police complaints in Chicago from the Invisible Institute’s Citizen Police Data Project. They focused only on complaints of excessive use of force, “such as unnecessary physical contact and unnecessary display of a weapon,” Dr. Freedman said. They considered a person exposed in the neighborhood if a complaint was reported in her census block in the year leading up to birth. During their study period, more than 6,000 complaints of excessive force were reported across an estimated 70% of the blocks.

The study population had an average age of 31 and included 59.5% White, 12% Black, 20% Hispanic, and 8.5% Asian people. Just over half the pregnancies (55%) were first-time pregnancies, and 3.3% of the population had a history of preterm birth (before 37 weeks). The researchers also gathered data to adjust for the study population’s:

• Age
• Parity (number of times the woman has given birth).
• Population size of census block.
• Exposure to a homicide on the block in the year leading up to birth.
• Socioeconomic status by block (based on a composite of median home value, median income, percentage of a high school diploma, and percentage employed).

“Those who lived in a block with an excessive force complaint were more likely to be Black, more likely to deliver preterm, and more likely to be exposed to homicide,” Dr. Freedman told attendees.

The proportion of pregnant women exposed to police complaints was 15.8%, and 10.2% lived in neighborhoods where a homicide occurred in the year leading up to birth. Within the group exposed to a homicide, 16.5% lived in a neighborhood with an excessive force complaint and 9.1% did not.

Overall, 8.1% of the population gave birth preterm. When stratified by whether or not they lived in a block with an excessive force complaint, the researchers found the proportion of preterm births was higher among those who did than those who did not (9.3% vs. 7.8%).

Both before and after adjusting for confounders, Black people were the only racial/ethnic group who had a significantly increased risk of preterm birth if they lived on a block with a complaint. They were nearly 30% more likely to deliver preterm if an excessive force complaint had been reported nearby (odds ratio, 1.29). The odds of preterm birth were slightly elevated for White people and slightly reduced for Hispanic and Asian people, but none of those associations reached significance.

In a sensitivity analysis comparing 189 Black individuals to themselves, the researchers compared those who had one preterm birth and one term birth. They found that the preterm birth was 32% more likely to occur in a year when an excessive force complaint was filed after adjusting for age and birth order (OR, 1.32; 95% confidence interval, 0.82-2.13).

“Police violence reflects just one component of structural racism,” Dr. Freedman said in an interview. “Our findings highlight the need to more thoroughly consider how these systemic and structural factors contribute to disparities in maternal and fetal health.”
 

Clinical and policy implications

The clinical implications of these findings focus on the need for obstetric clinical teams to understand patients’ stressors and to provide support and resources, according to Dr. Freedman’s mentor, Ann Borders, MD, MSc, MPH, a maternal-fetal medicine physician at NorthShore and Evanston Hospital and a clinical associate professor at the University of Chicago Pritzker School of Medicine.

“Potential strategies include training on improved listening and respectful patient-centered care, such as provided by the CDC Hear Her campaign, and consideration of universal social determinants of health screening during obstetric care,” Dr. Borders told this news organization..

Though the study included a large sample size and allowed the researchers to control for individual and neighborhood characteristics, Dr. Freedman acknowledged that census blocks may or may not correlate with the way individuals define their own neighborhoods. They also didn’t have the data to assess the quality of prenatal care or the type of preterm birth, but they are developing a qualitative study to determine the best ways of measuring exposure to police violence.

In addition, the researchers’ reliance only on formal police complaints could have underestimated prevalence of excessive force, and the study did not take into account people’s direct experience with police violence; police violence that occurs within a person’s social network; or police violence widely covered in the news. 

It wasn’t possible for the researchers to verify whether excessive force actually occurred or whether the force might have been justified, and it instead relied on the fact that someone lodged a complaint because he or she perceived the action as excessive.

Allison Bryant Mantha, MD, MPH, vice chair for Quality, Equity, and Safety at Massachusetts General Hospital in Boston and a board member of SMFM, said she was impressed with the adjustment of homicide exposure as a proxy for neighborhood crime.

“Many might assume that reports of police misconduct might be a marker for a ‘dangerous neighborhood,’ and it was thoughtful of the authors to adjust their analyses for exposure to crime to demonstrate that, even above and beyond crime, reports of police misconduct seem to be associated with adverse outcomes,” Dr. Bryant Mantha, who moderated the session, said in an interview.

Confronting this issue goes beyond what clinicians can do on their own, Dr. Bryant Mantha suggested.

“The greatest change will come with addressing the structural racism that underlies differential exposure to police misconduct in communities in the first place,” she said. “Concurrent with this, however, clinicians may consider adding in an assessment of neighborhood characteristics to include reports of police misconduct as they screen for other social determinants of health. While we do not have intervention studies to demonstrate efficacy, it is not a huge leap to imagine that recognition of this burden in individuals’ lives, plus offering ways to manage stress or seek redress, could be of benefit.”

The research was funded by the Eunice Kennedy Shriver National Institute of Child Health and Human Development, the National Institute on Minority Health and Health Disparities, and the Northwestern Medicine Enterprise Data Warehouse Pilot Data Program. Dr. Freedman, Dr. Borders, and Dr. Bryant Mantha have disclosed no relevant financial relationships.

• Age
• Parity (number of times the woman has given birth).
• Population size of census block.
• Exposure to a homicide on the block in the year leading up to birth.
• Socioeconomic status by block (based on a composite of median home value, median income, percentage of a high school diploma, and percentage employed).

“Those who lived in a block with an excessive force complaint were more likely to be Black, more likely to deliver preterm, and more likely to be exposed to homicide,” Dr. Freedman told attendees.

The proportion of pregnant women exposed to police complaints was 15.8%, and 10.2% lived in neighborhoods where a homicide occurred in the year leading up to birth. Within the group exposed to a homicide, 16.5% lived in a neighborhood with an excessive force complaint and 9.1% did not.

Overall, 8.1% of the population gave birth preterm. When stratified by whether or not they lived in a block with an excessive force complaint, the researchers found the proportion of preterm births was higher among those who did than those who did not (9.3% vs. 7.8%).

Both before and after adjusting for confounders, Black people were the only racial/ethnic group who had a significantly increased risk of preterm birth if they lived on a block with a complaint. They were nearly 30% more likely to deliver preterm if an excessive force complaint had been reported nearby (odds ratio, 1.29). The odds of preterm birth were slightly elevated for White people and slightly reduced for Hispanic and Asian people, but none of those associations reached significance.

In a sensitivity analysis comparing 189 Black individuals to themselves, the researchers compared those who had one preterm birth and one term birth. They found that the preterm birth was 32% more likely to occur in a year when an excessive force complaint was filed after adjusting for age and birth order (OR, 1.32; 95% confidence interval, 0.82-2.13).

“Police violence reflects just one component of structural racism,” Dr. Freedman said in an interview. “Our findings highlight the need to more thoroughly consider how these systemic and structural factors contribute to disparities in maternal and fetal health.”
 

Clinical and policy implications

The clinical implications of these findings focus on the need for obstetric clinical teams to understand patients’ stressors and to provide support and resources, according to Dr. Freedman’s mentor, Ann Borders, MD, MSc, MPH, a maternal-fetal medicine physician at NorthShore and Evanston Hospital and a clinical associate professor at the University of Chicago Pritzker School of Medicine.

“Potential strategies include training on improved listening and respectful patient-centered care, such as provided by the CDC Hear Her campaign, and consideration of universal social determinants of health screening during obstetric care,” Dr. Borders told this news organization..

Though the study included a large sample size and allowed the researchers to control for individual and neighborhood characteristics, Dr. Freedman acknowledged that census blocks may or may not correlate with the way individuals define their own neighborhoods. They also didn’t have the data to assess the quality of prenatal care or the type of preterm birth, but they are developing a qualitative study to determine the best ways of measuring exposure to police violence.

In addition, the researchers’ reliance only on formal police complaints could have underestimated prevalence of excessive force, and the study did not take into account people’s direct experience with police violence; police violence that occurs within a person’s social network; or police violence widely covered in the news. 

It wasn’t possible for the researchers to verify whether excessive force actually occurred or whether the force might have been justified, and it instead relied on the fact that someone lodged a complaint because he or she perceived the action as excessive.

Allison Bryant Mantha, MD, MPH, vice chair for Quality, Equity, and Safety at Massachusetts General Hospital in Boston and a board member of SMFM, said she was impressed with the adjustment of homicide exposure as a proxy for neighborhood crime.

“Many might assume that reports of police misconduct might be a marker for a ‘dangerous neighborhood,’ and it was thoughtful of the authors to adjust their analyses for exposure to crime to demonstrate that, even above and beyond crime, reports of police misconduct seem to be associated with adverse outcomes,” Dr. Bryant Mantha, who moderated the session, said in an interview.

Confronting this issue goes beyond what clinicians can do on their own, Dr. Bryant Mantha suggested.

“The greatest change will come with addressing the structural racism that underlies differential exposure to police misconduct in communities in the first place,” she said. “Concurrent with this, however, clinicians may consider adding in an assessment of neighborhood characteristics to include reports of police misconduct as they screen for other social determinants of health. While we do not have intervention studies to demonstrate efficacy, it is not a huge leap to imagine that recognition of this burden in individuals’ lives, plus offering ways to manage stress or seek redress, could be of benefit.”

The research was funded by the Eunice Kennedy Shriver National Institute of Child Health and Human Development, the National Institute on Minority Health and Health Disparities, and the Northwestern Medicine Enterprise Data Warehouse Pilot Data Program. Dr. Freedman, Dr. Borders, and Dr. Bryant Mantha have disclosed no relevant financial relationships.

An analysis of data from the U.S. military suggests that the maternal morbidity disparities between Black and White women cannot be attributed solely to differences in access to care and socioeconomics.

Even in the U.S. military health care system, where all service members have universal access to the same facilities and providers, researchers found substantial racial disparities in cesarean deliveries, maternal ICU admission, and overall severe maternal morbidity and mortality between Black patients and White patients, according to findings from a new study presented Jan. 28, 2021, at a meeting sponsored by the Society for Maternal-Fetal Medicine.

“This was surprising given some of the driving theories behind maternal race disparities encountered in this country, such as access to care and socioeconomic status, are controlled for in this health care system,” Capt. Jameaka Hamilton, MD, who presented the research, said in an interview. “Our findings indicate that there are likely additional factors at play which impact the obstetrical outcomes of women based upon their race, including systems-based barriers to accessing the military health care system which contribute to health care disparities, or in systemic or implicit biases which occur within our health care delivery.”

Plenty of recent research has documented the rise in maternal morbidity and mortality in the United States and the considerable racial disparities within those statistics. Black women are twice as likely to suffer morbidity and three to four times more likely to die in childbirth, compared with White women, Dr. Hamilton, an ob.gyn. from the San Antonio Uniformed Services Health Education Consortium at Ft. Sam Houston in San Antonio, Texas, reminded attendees. So far, much of this disparity has been attributed to social determinants of health.

Military retirees, active-duty personnel, and dependents, however, have equal access to federal health insurance and care at military health care facilities, or at covered civilian facilities where needed. Hence the researchers’ hypothesis that the military medical system would not show the same disparities by race that are seen in civilian populations.

The researchers analyzed maternal morbidity data from the Neonatal Perinatal Information Center from April 2018 to March 2019. The retrospective study included data from 13 military treatment facilities that had more than 1,000 deliveries per year. In addition to statistics on cesarean delivery and adult ICU admission, the researchers compared numbers on overall severe maternal morbidity based on the indicators defined by the Centers for Disease Control and Prevention.

The 15,305 deliveries included 23% Black patients and 77% White patients from the Air Force, Army, and Navy branches.

The cesarean delivery rate ranged from 19.4% to 35.5%. ICU admissions totaled 38 women, 190 women had postpartum hemorrhage, and 282 women experienced severe maternal morbidity. All three measures revealed racial disparities:

• Overall severe maternal morbidity occurred in 2.66% of Black women and 1.66% of White women (P =.0001).
• ICU admission occurred in 0.49% of Black women and 0.18% of White women (P =.0026).
• 31.68% of Black women had a cesarean delivery, compared with 23.58% of White women (P <.0001).

After excluding cases with blood transfusions, Black women were twice as likely to have severe maternal morbidity (0.64% vs. 0.32%). There were no significant differences in postpartum hemorrhage rates between Black and White women, but this analysis was limited by the small overall numbers of postpartum hemorrhage.

Among the study’s limitations were the inability to stratify patients by retiree, active duty, or dependent status, and the lack of data on preeclampsia rates, maternal age, obesity, or other preexisting conditions. In addition, the initial dataset included 61% of patients who reported their race as “other” than Black or White, limiting the number of patients whose data could be analyzed. Since low-volume hospitals were excluded, the outcomes could be skewed if lower-volume facilities are more likely to care for more complex cases, Dr. Hamilton added.

Allison Bryant Mantha, MD, MPH, vice chair for quality, equity, and safety in the ob.gyn. department at Massachusetts General Hospital, Boston, praised Dr. Hamilton’s work for revealing that differential access – though still problematic – cannot fully explain inequities between Black women and other women.

“The findings are not shocking given that what underlies some of these inequities – namely structural and institutional racism, and differential treatment within the system – are not exclusive to civilian health care settings,” Dr. Bryant Mantha, who moderated the session, said in an interview. “That said, doing the work to demonstrate this is extremely valuable.”

Although the causes of these disparities are systemic, Dr. Hamilton said individual providers can play a role in addressing them.

“There can certainly be more done to address this dangerous trend at the provider, hospital/institution, and national level,” she said. I think we as providers should continue to self-reflect and address our own biases. Hospitals and institutions should continue to develop policies that draw attention health care disparities.”

Completely removing these inequalities, however, will require confronting the racism embedded in U.S. health care at all levels, Dr. Bryant Mantha suggested.

“Ultimately, moving to an antiracist health care system – and criminal justice system, educational system, political system, etc. – and dismantling the existing structural racism in policies and practices will be needed to drive this change,” Dr. Bryant Mantha said. “Individual clinicians can use their voices to advocate for these changes in their health systems, communities, and states. Awareness of these inequities is critical, as is a sense of collective efficacy that we can, indeed, change the status quo.”

Dr. Hamilton and Dr. Bryant Mantha reported no disclosures.

Women at risk of preterm birth who took daily low-dose aspirin did not have significantly lower rates of preterm birth than those who did not take aspirin, according to preliminary findings from a small randomized controlled trial. There was a trend toward lower rates, especially among those with the highest compliance, but the study was underpowered to detect a difference with statistical significance, said Anadeijda Landman, MD, of the Amsterdam University Medical Center. Dr. Landman presented the findings Jan. 28 at a meeting sponsored by the Society for Maternal-Fetal Medicine.

Preterm birth accounts for a third of all neonatal mortality, she told attendees. Among 15 million preterm births worldwide each year, 65% are spontaneous, indicating the need for effective preventive interventions. Dr. Landman reviewed several mechanisms by which aspirin may help reduce preterm birth via different pathways.

The researchers’ multicenter, placebo-controlled trial involved 8 tertiary care and 26 secondary care hospitals in the Netherlands between May 2016 and June 2019. Starting between 8 and 15 weeks’ gestation, women took either 80 mg of aspirin or a placebo daily until 36 weeks’ gestation or delivery. Women also received progesterone, cerclage, or pessary as indicated according to local protocols.

The study enrolled 406 women with singleton pregnancy and a history of preterm birth delivered between 22 and 37 weeks’ gestation. The final analysis, after exclusions for pregnancy termination, congenital anomalies, multiples pregnancy, or similar reasons, included 193 women in the intervention group and 194 in the placebo group. The women had similar baseline characteristics across both groups except a higher number of past mid-trimester fetal deaths in the aspirin group.

“It’s important to realize these women had multiple preterm births, as one of our inclusion criteria was previous spontaneous preterm birth later than 22 weeks’ gestation, so this particular group is very high risk for cervical insufficiency as a probable cause,” Dr. Landman told attendees.

Among women in the aspirin group, 21.2% delivered before 37 weeks, compared with 25.4% in the placebo group (P = .323). The rate of spontaneous birth was 20.1% in the aspirin group and 23.8% in the placebo group (P = .376). Though still not statistically significant, the difference between the groups was larger when the researchers limited their analysis to the 245 women with at least 80% compliance: 18.5% of women in the aspirin group had a preterm birth, compared with 24.8% of women in the placebo group (P = .238).

There were no significant differences between the groups in composite poor neonatal outcomes or in a range of prespecified newborn complications. The aspirin group did have two stillbirths, two mid-trimester fetal losses, and two extremely preterm newborns (at 24+2 weeks and 25+2 weeks). The placebo group had two mid-trimester fetal losses.

“These deaths are inherent to the study population, and it seems unlikely they are related to the use of aspirin,” Dr. Landman said. “Moreover other aspirin studies have not found an increased perinatal mortality rate, and some large studies indicated the neonatal mortality rate is even reduced.”

Although preterm birth only trended lower in the aspirin group, Dr. Landman said the researchers believe they cannot rule out an effect from aspirin.

“It’s also important to note that our study was underpowered as the recurrence risk of preterm birth in our study was lower than expected, so it’s possible a small treatment effect of aspirin could not be demonstrated in our study,” she said. “And, despite the proper randomization procedure, many more women in the aspirin group had a previous mid-trimester fetal loss. This indicates that the aspirin group might be more at risk for preterm birth than the placebo group, and this imbalance could also have diminished a small protective effect of aspirin.”

In response to an audience question, Dr. Landman acknowledged that more recent studies on aspirin have used 100- to 150-mg dosages, but that evidence was not as clear when their study began in 2015. She added that her research team does not advise changing clinical care currently and believes it is too soon to recommend aspirin to this population.

Tracy Manuck, MD, MS, an associate professor of ob.gyn. at the University of North Carolina in Chapel Hill, agreed that it is premature to begin prescribing aspirin for preterm birth prevention, but she noted that most of the patients she cares for clinically already meet criteria for aspirin based on their risk factors for preeclampsia.

“Additional research is needed in the form of a well-designed and large [randomized, controlled trial],” Dr Manuck, who moderated the session, said in an interview. “However, such a trial is becoming increasingly difficult to conduct because so many pregnant women qualify to receive aspirin for the prevention of preeclampsia due to their weight, medical comorbidities, or prior pregnancy history.”

She said she anticipates seeing patient-level data meta-analyses in the coming months as more data on aspirin for preterm birth prevention are published.

“Given that these data are supportive of the overall trends seen in prior publications, I do think that low-dose aspirin will eventually bear out as a helpful preventative measure to prevent recurrent preterm birth. Aspirin is low risk, readily available, and is inexpensive,” Dr. Manuck said. “I hope that meta-analysis data will provide additional information regarding the benefit of low-dose aspirin for prematurity prevention.”

Though still not statistically significant, the difference between the groups was larger when the researchers limited their analysis to the 245 women with at least 80% compliance: 18.5% of women in the aspirin group had a preterm birth, compared with 24.8% of women in the placebo group (P = .238).

There were no significant differences between the groups in composite poor neonatal outcomes or in a range of prespecified newborn complications. The aspirin group did have two stillbirths, two mid-trimester fetal losses, and two extremely preterm newborns (at 24+2 weeks and 25+2 weeks). The placebo group had two mid-trimester fetal losses.

“These deaths are inherent to the study population, and it seems unlikely they are related to the use of aspirin,” Dr. Landman said. “Moreover other aspirin studies have not found an increased perinatal mortality rate, and some large studies indicated the neonatal mortality rate is even reduced.”

Although preterm birth only trended lower in the aspirin group, Dr. Landman said the researchers believe they cannot rule out an effect from aspirin.

“It’s also important to note that our study was underpowered as the recurrence risk of preterm birth in our study was lower than expected, so it’s possible a small treatment effect of aspirin could not be demonstrated in our study,” she said. “And, despite the proper randomization procedure, many more women in the aspirin group had a previous mid-trimester fetal loss. This indicates that the aspirin group might be more at risk for preterm birth than the placebo group, and this imbalance could also have diminished a small protective effect of aspirin.”

In response to an audience question, Dr. Landman acknowledged that more recent studies on aspirin have used 100- to 150-mg dosages, but that evidence was not as clear when their study began in 2015. She added that her research team does not advise changing clinical care currently and believes it is too soon to recommend aspirin to this population.

Tracy Manuck, MD, MS, an associate professor of ob.gyn. at the University of North Carolina in Chapel Hill, agreed that it is premature to begin prescribing aspirin for preterm birth prevention, but she noted that most of the patients she cares for clinically already meet criteria for aspirin based on their risk factors for preeclampsia.

“Additional research is needed in the form of a well-designed and large [randomized, controlled trial],” Dr Manuck, who moderated the session, said in an interview. “However, such a trial is becoming increasingly difficult to conduct because so many pregnant women qualify to receive aspirin for the prevention of preeclampsia due to their weight, medical comorbidities, or prior pregnancy history.”

She said she anticipates seeing patient-level data meta-analyses in the coming months as more data on aspirin for preterm birth prevention are published.

“Given that these data are supportive of the overall trends seen in prior publications, I do think that low-dose aspirin will eventually bear out as a helpful preventative measure to prevent recurrent preterm birth. Aspirin is low risk, readily available, and is inexpensive,” Dr. Manuck said. “I hope that meta-analysis data will provide additional information regarding the benefit of low-dose aspirin for prematurity prevention.”

The research was funded by the Dutch Organization for Health Care Research and the Dutch Consortium for Research in Women’s Health. Dr. Landman and Dr. Manuck had no disclosures.
