Whether to test laboring women for SARS-CoV-2 may hinge on regional prevalence
at the time of admission, research published online in Obstetrics & Gynecology suggests.
In Los Angeles, researchers stopped universal testing after none of the first 80 asymptomatic women had positive results. Researchers in Chicago, on the other hand, found a positive rate of approximately 1.6% among 614 asymptomatic patients and continue to test all patients.
“Decisions regarding universal testing need to be made in the context of regional prevalence of COVID-19 infection, with recognition that a ‘one-size-fits-all’ approach is unlikely to be justifiable,” Torri D. Metz, MD,of University of Utah Health in Salt Lake City said in an editorial accompanying research letters that described the experience in Los Angeles and Chicago. “In the setting of low population prevalence of COVID-19 infection or in locations with limited testing availability, deferring universal testing may represent the better part of valor when weighing risks, benefits, economic burden, and unintended consequences of testing for SARS-CoV-2 infection. In high-prevalence regions, universal testing may be a valuable addition to obstetric care that will prevent infections in health care workers and neonates.”
Testing all patients also may provide valuable population-level surveillance, added Dr. Metz, who is an associate professor of obstetrics and gynecology, a maternal-fetal medicine subspecialist, and vice-chair of research in obstetrics and gynecology.
One week of data
After New York hospitals reported an approximately 13% prevalence of SARS-CoV-2 infection among asymptomatic laboring women, Cedars-Sinai Medical Center in Los Angeles changed its policy from testing only women with COVID-19 symptoms to testing all women beginning April 4, 2020. “Data from New York made us very concerned about the possibility of asymptomatic infections among our own pregnant patients,” Mariam Naqvi, MD, a maternal-fetal medicine specialist at Cedars-Sinai Medical Center, said in a news release. “This would have implications for them, their babies, their households, and for the health of our staff caring for them.”
In 1 week, 82 pregnant women admitted to the obstetric unit were tested for SARS-CoV-2 infection. Of two women who reported COVID-19 symptoms, one tested positive for SARS-CoV-2. “Of the remaining 80 asymptomatic women, none tested positive for SARS-CoV-2 infection, and all remained symptom free throughout their hospitalizations,” Dr. Naqvi and colleagues reported. “One asymptomatic patient had an inadequate nasopharyngeal specimen and declined repeat testing.”
Precautions taken during universal testing meant that all members of the treatment team used valuable personal protective equipment. In some cases, mothers and newborns were separated until test results were available.
“We discontinued universal testing after a 7-day period, because we could not justify continued testing of asymptomatic women in the absence of positive test results for SARS-CoV-2 infection,” they noted. “Though universal testing did not yield enough positive results on our obstetric unit to warrant continued testing at this time, our approach may change if local rates of infection increase.”
20 days of testing
In a prospective case series of pregnant women admitted to Northwestern Memorial Hospital in Chicago from April 8 to April 27, 2020, universal testing did detect asymptomatic infections. Women with scheduled admissions were tested 12-36 hours before admission in a drive-through testing center, and women with unscheduled admissions received a test that has a 2- to 3-hour turnaround time. In addition, patients were screened for symptoms such as fever, shortness of breath, cough, sore throat, body aches, chills, new-onset vomiting, diarrhea, loss of taste or smell, and red or painful eyes.
“Asymptomatic women with pending tests were managed on the routine labor floor, but health care workers used personal protective equipment that included a respirator during the second stage of labor and delivery until the test result became available,” wrote Emily S. Miller, MD, MPH, of Northwestern University, Chicago, and colleagues.
During the first 20 days of universal testing, 635 pregnant women were admitted, and 23 (3.6%) tested positive for SARS-CoV-2 infection. Of 21 women with COVID-19 symptoms, 13 (62%) tested positive for SARS-CoV-2 infection. Of 614 women who were asymptomatic, 10 (1.6%) tested positive for SARS-CoV-2. “Our data corroborate the observation that pregnant women with SARS-CoV-2 infection on admission do not seem to be reliably identified using symptom screening alone,” the researchers wrote.
Unintended consequences
Despite a lack of effective treatments for mild to moderate COVID-19, “knowledge of the disease state allows ... health care workers to wear appropriate personal protective equipment to avoid exposure,” Dr. Metz wrote. It also allows “women to be counseled about ways to decrease transmission to neonates” and enables close monitoring of patients with infection.
At the same time, universal testing may have unintended consequences for infected patients, such as stigmatization, separation from the newborn, and delays in care related to health care providers spending more time donning personal protective equipment or changes in medical decision-making regarding cesarean delivery, she emphasized.
“Obstetricians should remain aware of disease prevalence in their communities and consider universal screening of asymptomatic women on an ongoing basis as new ‘hot spots’ for COVID-19 infection are identified,” Dr. Metz concluded.
One of Dr. Naqvi’s coauthors disclosed receiving funds from Contemporary OB/GYN, Keneka, and the American College of Obstetricians and Gynecologists and serving as a board examiner for the American Board of Obstetrics and Gynecology; her coauthors did not report any relevant financial disclosures. Dr. Metz disclosed that money was paid to her institution from Pfizer and GestVision for work related to an RSV vaccination trial and a preeclampsia test, respectively. Dr. Miller and colleagues did not report any potential conflicts of interest.

Should all patients with advanced ovarian cancer receive frontline maintenance therapy?
The current standard frontline therapy for advanced epithelial ovarian, fallopian tube, and primary peritoneal cancer includes a combination of surgical cytoreduction and at least six cycles of platinum-based chemotherapy. While this achieves a complete clinical response (“remission”) in most, 85% of patients will recur and eventually succumb to the disease. This suggests that treatments are good at inducing remission, but poor at eradicating the disease altogether. This has motivated the consideration of maintenance therapy: extended treatment beyond completion of chemotherapy during the period of time when patients are clinically disease free.
Maintenance therapy is an appealing concept for clinicians who desperately want to “hold” their patients in a disease-free state for longer periods. It is also a profitable way to administer therapy as there is more compensation to the pharmaceutical industry from chronic, long-term drug administration rather than episodic treatment courses. However, the following question must be asked: Is this extended therapy worthwhile for all patients, and is it good value?
In the past 12 months, three major industry-sponsored clinical trials have been published (PRIMA, PAOLA-1, and VELIA)which suggest a benefit for all patients with advanced epithelial ovarian cancer in receiving prolonged poly (ADP-ribose) polymerase inhibitor (PARPi) therapy after primary chemotherapy.1-3 This has resulted in Food and Drug Administration approval for some of these agents as maintenance therapy. Despite differences in the drugs tested and the timing of therapy, these studies observed that treatment of advanced ovarian cancer with the addition of a PARPi during and/or after carboplatin and paclitaxel chemotherapy for up to an additional 3 years resulted in a longer progression-free survival (PFS) of approximately 6 months. PFS is defined as the time to measurable recurrence or death. However, this positive effect was not equally distributed across the whole population; rather, it appeared to be created by a substantial response in a smaller subgroup.
PARP inhibitor therapies such as olaparib, niraparib, veliparib, and rucaparib target a family of enzymes that repair DNA and stabilize the human genome through the repair of single-stranded DNA breaks. Inhibiting these enzymes facilitates the accumulation of single-stranded breaks, allowing the development of double-strand breaks, which in turn cannot be repaired if the cell has deficient homologous recombination (HRD) such as through a germline or somatic BRCA mutation, or alternative relevant mutation that confers a similar effect. The opportunistic pairing of a drug interaction with a pathway specific to the cancer is an example of a targeted therapy.
In order to improve the value of cancer drug therapy, there has been emphasis by cooperative research groups, such as the Gynecologic Oncology Group, to study the efficacy of targeted therapies, such as PARPi, in patients identified by biomarkers such as tumors that possess germline or somatic HRD in whom they are most likely to work. This approach makes good common sense and promises to deliver a large magnitude of clinical benefit in a smaller focused population. Therefore, even if drug costs are high, the treatment may still have value. Consistent with that principle, the recently published VELIA, PRIMA, and PAOLA-1 trials all showed impressive benefit in PFS (on average 11-12 months) for the subgroup of patients with HRD. However, these studies were designed and funded by the pharmaceutical industry, and abandoned the principle of biomarker-driven targeted therapy. They did not limit their studies to the HRD-positive population most likely to benefit, but instead included and reported on the impact on all-comers (patients with both HRD and HR-proficient tumors). Subsequently their final conclusions could be extrapolated to the general population of ovarian cancer patients, and in doing so, a larger share of the marketplace.
Only 30% of the general population of ovarian, fallopian tube and primary peritoneal cancer patients carry a germline or somatic BRCA mutation and less than half carry this or alternative mutations which confer HRD. The remaining majority are HR-proficient tumors. However, the three study populations in the aforementioned trials were enriched for HRD tumors with 50%-60% subjects carrying germline or somatic HRD. Therefore, it is likely that the observed benefits in the “intent-to-treat” group were larger than what a clinician would observe in their patient population. Additionally, the large (11-12 month) gains in the HRD-positive group may have been so significant that they compensated for the subtle impact in the HR-proficient population (less than 3 months), resulting in an average total effect that, while being statistically significant for “all comers,” was actually only clinically significant for the HRD group. The positive impact for HRD tumors effectively boosted the results for the group as a whole.
The use of PFS as a primary endpoint raises another significant concern with the design of these PARPi maintenance trials. Much has been written about the importance of PFS as an endpoint for ovarian cancer because of confounding effects of subsequent therapy and to minimize the costs and duration of clinical trials.4 PFS is a quicker, less expensive endpoint to capture than overall survival. It usually correlates with overall survival, but typically only when there is a large magnitude of benefit in PFS. These arguments are fair when considering episodic drug therapies in the setting of measurable, active disease. However, maintenance therapy is given during a period of what patients think of as remission. Remission is valued by patients because it is a gateway to cure, and also because it is a time devoid of symptoms of disease, toxicity (therapeutic and financial), and the burden of frequent medical visits and interventions. While PFS is a measure of the length of remission, it is not a measure of cure. We should ask: What does it mean to a patient if she has a longer remission but needs to be on drug therapy (with its associated burdens and toxicities) in order to maintain that remission? We know that an increase in PFS with maintenance therapy does not always result in a commensurate increase in survival. One does not always precede the other. An example of this is the use of maintenance bevacizumab following upfront chemotherapy which improves PFS by 4 months, but is not associated with an increase in survival.5
When considering the value and ethics of maintenance therapy, it should be associated with a proven survival benefit or an improvement in quality of life. With respect to PARPi maintenance, we lack the data regarding the former, and have contrary evidence regarding the latter. In these three trials, PARPi maintenance was associated with significantly more toxicity than placebo including the commonly observed nausea and fatigue. Most of us would not like to be on a drug therapy for 3 years that made us feel nauseated or fatigued if it didn’t also increase our chance of cure or a longer life. While the significant PFS benefit of maintenance PARPi that is consistently observed in HRD-positive ovarian cancers suggests there will also likely be a clinically significant improvement in survival and cure in that specific subpopulation, this is less likely true for the majority of women with HR-proficient ovarian cancers. Time will tell this story, but as yet, we don’t know.
The use of maintenance PARPi therapy during and/or after primary cytotoxic chemotherapy for advanced epithelial ovarian, primary peritoneal, and fallopian tube cancer is associated with a substantial benefit in time to recurrence in a population with HRD tumors and a small benefit among the majority who don’t. However, it comes at the cost of toxicity at a time when patients would otherwise be free of disease and treatment. I propose that, until a survival benefit for all women has been observed, we should consider a targeted and biomarker-driven approach to maintenance PARPi prescription, favoring prescription for those with germline or somatic HRD mutations.

The current standard frontline therapy for advanced epithelial ovarian, fallopian tube, and primary peritoneal cancer includes a combination of surgical cytoreduction and at least six cycles of platinum-based chemotherapy. While this achieves a complete clinical response (“remission”) in most, 85% of patients will recur and eventually succumb to the disease. This suggests that treatments are good at inducing remission, but poor at eradicating the disease altogether. This has motivated the consideration of maintenance therapy: extended treatment beyond completion of chemotherapy during the period of time when patients are clinically disease free.
Maintenance therapy is an appealing concept for clinicians who desperately want to “hold” their patients in a disease-free state for longer periods. It is also a profitable way to administer therapy as there is more compensation to the pharmaceutical industry from chronic, long-term drug administration rather than episodic treatment courses. However, the following question must be asked: Is this extended therapy worthwhile for all patients, and is it good value?
In the past 12 months, three major industry-sponsored clinical trials have been published (PRIMA, PAOLA-1, and VELIA)which suggest a benefit for all patients with advanced epithelial ovarian cancer in receiving prolonged poly (ADP-ribose) polymerase inhibitor (PARPi) therapy after primary chemotherapy.1-3 This has resulted in Food and Drug Administration approval for some of these agents as maintenance therapy. Despite differences in the drugs tested and the timing of therapy, these studies observed that treatment of advanced ovarian cancer with the addition of a PARPi during and/or after carboplatin and paclitaxel chemotherapy for up to an additional 3 years resulted in a longer progression-free survival (PFS) of approximately 6 months. PFS is defined as the time to measurable recurrence or death. However, this positive effect was not equally distributed across the whole population; rather, it appeared to be created by a substantial response in a smaller subgroup.
PARP inhibitor therapies such as olaparib, niraparib, veliparib, and rucaparib target a family of enzymes that repair DNA and stabilize the human genome through the repair of single-stranded DNA breaks. Inhibiting these enzymes facilitates the accumulation of single-stranded breaks, allowing the development of double-strand breaks, which in turn cannot be repaired if the cell has deficient homologous recombination (HRD) such as through a germline or somatic BRCA mutation, or alternative relevant mutation that confers a similar effect. The opportunistic pairing of a drug interaction with a pathway specific to the cancer is an example of a targeted therapy.
In order to improve the value of cancer drug therapy, there has been emphasis by cooperative research groups, such as the Gynecologic Oncology Group, to study the efficacy of targeted therapies, such as PARPi, in patients identified by biomarkers such as tumors that possess germline or somatic HRD in whom they are most likely to work. This approach makes good common sense and promises to deliver a large magnitude of clinical benefit in a smaller focused population. Therefore, even if drug costs are high, the treatment may still have value. Consistent with that principle, the recently published VELIA, PRIMA, and PAOLA-1 trials all showed impressive benefit in PFS (on average 11-12 months) for the subgroup of patients with HRD. However, these studies were designed and funded by the pharmaceutical industry, and abandoned the principle of biomarker-driven targeted therapy. They did not limit their studies to the HRD-positive population most likely to benefit, but instead included and reported on the impact on all-comers (patients with both HRD and HR-proficient tumors). Subsequently their final conclusions could be extrapolated to the general population of ovarian cancer patients, and in doing so, a larger share of the marketplace.
Only 30% of the general population of ovarian, fallopian tube and primary peritoneal cancer patients carry a germline or somatic BRCA mutation and less than half carry this or alternative mutations which confer HRD. The remaining majority are HR-proficient tumors. However, the three study populations in the aforementioned trials were enriched for HRD tumors with 50%-60% subjects carrying germline or somatic HRD. Therefore, it is likely that the observed benefits in the “intent-to-treat” group were larger than what a clinician would observe in their patient population. Additionally, the large (11-12 month) gains in the HRD-positive group may have been so significant that they compensated for the subtle impact in the HR-proficient population (less than 3 months), resulting in an average total effect that, while being statistically significant for “all comers,” was actually only clinically significant for the HRD group. The positive impact for HRD tumors effectively boosted the results for the group as a whole.
The use of PFS as a primary endpoint raises another significant concern with the design of these PARPi maintenance trials. Much has been written about the importance of PFS as an endpoint for ovarian cancer because of confounding effects of subsequent therapy and to minimize the costs and duration of clinical trials.4 PFS is a quicker, less expensive endpoint to capture than overall survival. It usually correlates with overall survival, but typically only when there is a large magnitude of benefit in PFS. These arguments are fair when considering episodic drug therapies in the setting of measurable, active disease. However, maintenance therapy is given during a period of what patients think of as remission. Remission is valued by patients because it is a gateway to cure, and also because it is a time devoid of symptoms of disease, toxicity (therapeutic and financial), and the burden of frequent medical visits and interventions. While PFS is a measure of the length of remission, it is not a measure of cure. We should ask: What does it mean to a patient if she has a longer remission but needs to be on drug therapy (with its associated burdens and toxicities) in order to maintain that remission? We know that an increase in PFS with maintenance therapy does not always result in a commensurate increase in survival. One does not always precede the other. An example of this is the use of maintenance bevacizumab following upfront chemotherapy which improves PFS by 4 months, but is not associated with an increase in survival.5
When considering the value and ethics of maintenance therapy, it should be associated with a proven survival benefit or an improvement in quality of life. With respect to PARPi maintenance, we lack the data regarding the former, and have contrary evidence regarding the latter. In these three trials, PARPi maintenance was associated with significantly more toxicity than placebo including the commonly observed nausea and fatigue. Most of us would not like to be on a drug therapy for 3 years that made us feel nauseated or fatigued if it didn’t also increase our chance of cure or a longer life. While the significant PFS benefit of maintenance PARPi that is consistently observed in HRD-positive ovarian cancers suggests there will also likely be a clinically significant improvement in survival and cure in that specific subpopulation, this is less likely true for the majority of women with HR-proficient ovarian cancers. Time will tell this story, but as yet, we don’t know.
The use of maintenance PARPi therapy during and/or after primary cytotoxic chemotherapy for advanced epithelial ovarian, primary peritoneal, and fallopian tube cancer is associated with a substantial benefit in time to recurrence in a population with HRD tumors and a small benefit among the majority who don’t. However, it comes at the cost of toxicity at a time when patients would otherwise be free of disease and treatment. I propose that, until a survival benefit for all women has been observed, we should consider a targeted and biomarker-driven approach to maintenance PARPi prescription, favoring prescription for those with germline or somatic HRD mutations.

Hyperkalemia most common adverse event in women taking spironolactone
, according to new research.
Spironolactone, which is approved to treat heart failure, hypertension, edema, and primary hyperaldosteronism, has antagonistic effects on progesterone and androgen receptors and has been used as an off-label treatment for acne in women. “Numerous guidelines have recommended its off-label use for acne therapy to avoid antibiotic resistance and potential side effects,” wrote Yu Wang of Stony Brook (N.Y.) University and Shari R. Lipner MD, PhD, of Weill Cornell Medicine, New York. Their report is in the International Journal of Women’s Dermatology.
In a retrospective study, the investigators analyzed 7,920 adverse events with spironolactone reported by women of all ages between Jan. 1, 1969, and Dec. 30, 2018, to the Food and Drug Administration’s Adverse Event Reporting System database, for all indications. The most common adverse event was hyperkalemia, reported in 16.1%, followed by kidney injury (15.2%) and drug interactions (9%). Of the 1,272 cases of hyperkalemia reported, 25 occurred in women aged 45 years or younger; 59.3% occurred in women aged 65-85 years.
While spironolactone prescribing information was not available, the investigators compared yearly reports of adverse events with annual public interest in spironolactone using the Google Trends search term spironolactone and annual scholarly mentions of spironolactone in the Altmetric database. There was a strong correlation between the number of cases reported to the FDA and the Google Trends search (Spearman coefficient, 0.94; P less than .001) and to the Altmetric database (Spearman coefficient, 0.64; P less than .01).
Noting that hyperkalemia is “exceptionally uncommon” in women aged 45 years and younger, the investigators concluded that “in the absence of risk factors for hyperkalemia or reduced renal function, potassium laboratory monitoring is unnecessary in younger females taking spironolactone.” Because the incidence increases with age, “interval laboratory monitoring is recommended for females older than 45 years old,” they noted.
Limitations of the study, they noted, include the retrospective design and no available data before 1969. “In addition, since the [FDA Adverse Event Reporting System] data does not differentiate whether spironolactone was prescribed for heart failure, hypertension, edema, primary hyperaldosteronism, or for acne,” the study could not control for these or other confounding comorbidities or associated therapies.
“For future studies, it is important to analyze drug interactions more carefully to determine which other medications may potentiate the risk for hyperkalemia in patients taking spironolactone. It is also important to quantitate overall U.S. prescription data to better understand the relative frequency of these adverse effects reported to the FDA,” they wrote.
The investigators reported that they had no conflicts of interest; the study had no funding.

Seek safe strategies to diagnose gestational diabetes during pandemic
Clinicians and pregnant women are less likely to prescribe and undergo the oral glucose tolerance test (OGTT) to diagnose gestational diabetes in the context of the COVID-19 pandemic, according to a review by H. David McIntyre, MD, of the University of Queensland, Brisbane, Australia, and Robert G. Moses, MD, of Wollongong (Australia) Hospital.
National and international discussions of whether a one- or two-step test for gestational diabetes mellitus (GDM) is optimal, and which women should be tested are ongoing, but the potential for exposure risks to COVID-19 are impacting the test process, they wrote in a commentary published in Diabetes Care.
“Any national or local guidelines should be developed with the primary aim of being protective for pregnant women and workable in the current health crisis,” they wrote.
Key concerns expressed by women and health care providers include the need for travel to be tested, the possible need for two visits, and the several hours spent in a potentially high-risk specimen collection center.
“Further, a GDM diagnosis generally involves additional health service visits for diabetes education, glucose monitoring review, and fetal ultrasonography, all of which carry exposure risks during a pandemic,” Dr. McIntyre and Dr. Moses noted.
Professional societies in the United Kingdom, Canada, and Australia have issued guidance to clinicians for modifying GDM diagnoses criteria during the pandemic that aim to reduce the need for the oral glucose tolerance test both during and after pregnancy.
Pandemic guidelines for all three of these countries support the identification of GDM using early pregnancy hemoglobin A1c (HbA1c) of at least 41 mmol/mol (5.9%).
Then, professionals in the United Kingdom recommend testing based on risk factors and diagnosing GDM based on any of these criteria: HbA1c of at least 39 mmol/mol (5.7%), fasting venous plasma glucose of at least 5.6 mmol/L (preferred), or random VPG of at least 9.0 mmol/L.
The revised testing pathway for Canada accepts an HbA1c of at least 39 mmol/mol (5.7%) and/or random VPG of at least 11.1 mmol/L.
“The revised Australian pathway does not include HbA1c but recommends a fasting VPG with progression to OGTT only if this result is 4.7-5.0 mmol/L,” Dr. McIntyre and Dr. Moses explained.
Overall, the revised guidelines for GDM testing will likely miss some women and only identify those with higher levels of hyperglycemia, the authors wrote. In addition, “the evidence base for these revised pathways is limited and that each alternative strategy should be evaluated over the course of the current pandemic.”
Validation of new testing strategies are needed, and the pandemic may provide and opportunity to adopt an alternative to the OGTT. The World Health Organization has not issued revised guidance for other methods of testing, but fasting VPG alone may be the simplest and most cost effective, at least for the short term, they noted.
“In this ‘new COVID world,’ GDM should not be ignored but pragmatically merits a lower priority than the avoidance of exposure to the COVID-19 virus,” although no single alternative strategy applies in all countries and situations, the authors concluded. Pragmatic measures and documentation of outcomes at the local level will offer the “least worst” solution while the pandemic continues.

A major concern against the backdrop of COVID-19 is ensuring long-term health while urgent care is – understandably so – being prioritized over preventive care. We can already see the impact that the decrease in primary care has had: Rates of childhood vaccination appear to have dropped; the cancellation or indefinite delay of elective medical procedures has meant a reduction in preventive cancer screenings, such as colonoscopies and mammograms; and concerns about COVID-19 may be keeping those experiencing cardiac events from seeking emergency care.
However, an outcropping of the coronavirus pandemic is an ingenuity to adapt to our new “normal.” Medical licenses have been recognized across state lines to allow much-needed professionals to practice in the hardest-hit areas. Doctors retrofitted a sleep apnea machine to be used as a makeshift ventilator. Those in the wearable device market now have a greater onus to deliver on quality, utility, security, and accuracy.
Obstetricians have had to dramatically change delivery of ante-, intra- and postpartum care. The recent commentary by Dr. McIntyre and Dr. Moses focuses on one particular area of concern: screening, diagnosis, and management of gestational diabetes mellitus (GDM).
Screening and diagnosis are mainstays to reduce the adverse maternal and neonatal outcomes of diabetes in pregnancy. Although there is no universally accepted approach to evaluating GDM, all current methods utilize an oral glucose tolerance test (OGTT), which requires significant time spent in a clinical office setting, thus increasing risk for COVID-19 exposure.
Several countries have adopted modified GDM criteria within the last months. At the time of this writing, the United States has not. Although not testing women for GDM, which is what Dr. McIntyre and Dr. Moses point out may be happening in countries with modified guidelines, seems questionable, perhaps we should think differently about our approach.
More than 20 years ago, it was reported that jelly beans could be used as an alternative to the 50-g GDM screening test (Am J Obstet Gynecol. 1999 Nov;181[5 Pt 1]:1154‐7; Am J Obstet Gynecol. 1995 Dec;173[6]:1889‐92); more recently, candy twists were used with similar results (Am J Obstet Gynecol. 2015 Apr;212[4]:522.e1-5). In addition, a number of articles have reported on the utility of capillary whole blood glucose measurements to screen for GDM in developing and resource-limited countries (Diabetes Technol Ther. 2011;13[5]:586‐91; Acta Diabetol. 2016 Feb;53[1]:91‐7; Diabetes Technol Ther. 2012 Feb;14[2]:131-4). Therefore, rather than forgo GDM screening, women could self-administer a jelly bean test at home, measure blood sugar with a glucometer, and depending on the results, have an OGTT. Importantly, this would allow ob.gyns. to maintain medical standards while managing patients via telemedicine.
We have evidence that GDM can establish poor health for generations. We know that people with underlying conditions have greater morbidity and mortality from infectious diseases. We recognize that accurate screening and diagnosis is the key to prevention and management. Rather than accept a “least worst” scenario, as Dr. McIntyre and Dr. Moses state, we must find ways to provide the best possible care under the current circumstances.

Overall, the revised guidelines for GDM testing will likely miss some women and only identify those with higher levels of hyperglycemia, the authors wrote. In addition, “the evidence base for these revised pathways is limited and that each alternative strategy should be evaluated over the course of the current pandemic.”
Validation of new testing strategies are needed, and the pandemic may provide and opportunity to adopt an alternative to the OGTT. The World Health Organization has not issued revised guidance for other methods of testing, but fasting VPG alone may be the simplest and most cost effective, at least for the short term, they noted.
“In this ‘new COVID world,’ GDM should not be ignored but pragmatically merits a lower priority than the avoidance of exposure to the COVID-19 virus,” although no single alternative strategy applies in all countries and situations, the authors concluded. Pragmatic measures and documentation of outcomes at the local level will offer the “least worst” solution while the pandemic continues.

Clinicians and pregnant women are less likely to prescribe and undergo the oral glucose tolerance test (OGTT) to diagnose gestational diabetes in the context of the COVID-19 pandemic, according to a review by H. David McIntyre, MD, of the University of Queensland, Brisbane, Australia, and Robert G. Moses, MD, of Wollongong (Australia) Hospital.
National and international discussions of whether a one- or two-step test for gestational diabetes mellitus (GDM) is optimal, and which women should be tested are ongoing, but the potential for exposure risks to COVID-19 are impacting the test process, they wrote in a commentary published in Diabetes Care.
“Any national or local guidelines should be developed with the primary aim of being protective for pregnant women and workable in the current health crisis,” they wrote.
Key concerns expressed by women and health care providers include the need for travel to be tested, the possible need for two visits, and the several hours spent in a potentially high-risk specimen collection center.
“Further, a GDM diagnosis generally involves additional health service visits for diabetes education, glucose monitoring review, and fetal ultrasonography, all of which carry exposure risks during a pandemic,” Dr. McIntyre and Dr. Moses noted.
Professional societies in the United Kingdom, Canada, and Australia have issued guidance to clinicians for modifying GDM diagnoses criteria during the pandemic that aim to reduce the need for the oral glucose tolerance test both during and after pregnancy.
Pandemic guidelines for all three of these countries support the identification of GDM using early pregnancy hemoglobin A1c (HbA1c) of at least 41 mmol/mol (5.9%).
Then, professionals in the United Kingdom recommend testing based on risk factors and diagnosing GDM based on any of these criteria: HbA1c of at least 39 mmol/mol (5.7%), fasting venous plasma glucose of at least 5.6 mmol/L (preferred), or random VPG of at least 9.0 mmol/L.
The revised testing pathway for Canada accepts an HbA1c of at least 39 mmol/mol (5.7%) and/or random VPG of at least 11.1 mmol/L.
“The revised Australian pathway does not include HbA1c but recommends a fasting VPG with progression to OGTT only if this result is 4.7-5.0 mmol/L,” Dr. McIntyre and Dr. Moses explained.

FDA approves Phexxi for use as an on-demand contraceptive
Evofem Biosciences expects to release Phexxi – the first nonhormonal, on-demand, vaginal pH regulator contraceptive designed to maintain vaginal pH within the range of 3.5-4.5 – in September 2020 alongside the Phexxi Concierge Experience, a comprehensive patient and health care provider telemedicine support system, according to the company’s press release. The service is designed to provide physicians with on-demand educational support, and to speed and simplify women’s access to Phexxi.
In an open-label multicenter trial, women aged 18-35 with regular menstrual cycles intravaginally administered a 5-gram dose of Phexxi vaginal gel up to 1 hour prior to intercourse; they did so for up to seven cycles. There were 101 pregnancies in 1,183 subjects during 4,769 cycles. The 7-cycle cumulative pregnancy rate was 14% (95% confidence interval: 10.0%, 17.5%).
The most common adverse events associated with Phexxi were vulvovaginal burning sensation, vulvovaginal pruritus, vulvovaginal mycotic infection, urinary tract infection, bacterial vaginosis, vaginal discharge, dysuria, and vulvovaginal pain.

Most patients with lichen sclerosus receive appropriate treatment
The claims-based prevalence of 0.05% found in the study is lower than previously reported, and only 16% of the diagnoses were in women aged 18-44 years, Laura E. Melnick, MD, and associates wrote after identifying 10,004 females aged 0-65 years with lichen sclerosus in the IBM MarketScan Commercial Claims and Encounters Databases from 2015 to 2017. The majority (79%) of those diagnosed were aged 45-65 years (average, 50.8 years).
In pediatric patients (up to age 17 years), the low prevalence (0.01%) “may be attributable to several factors including relative rarity, as well as variability in pediatric clinicians’ familiarity with [lichen sclerosus] and in patients’ clinical symptoms,” said Dr. Melnick and associates in the department of dermatology at New York University.
Just over half of all diagnoses (52.4%) were made by ob.gyns., with dermatologists next at 14.5%, followed by family physicians (6.5%), nurse practitioners (2.5%), and internists (0.4%), they reported in the International Journal of Women’s Dermatology.
Treatment for lichen sclerosus, in the form of high-potency topical corticosteroids, was mostly appropriate. Ob.gyns. prescribed class 1/2 steroids to 83% of their patients, tops among all clinicians. Dermatologists were just over 80%, and the other clinician categories were all over 70%, the investigators said.
“Understanding the current management of [lichen sclerosus] is important given that un- or undertreated disease can significantly impact patients’ quality of life, lead to increased lower urinary tract symptoms and irreversible architectural changes, and predispose women to squamous cell carcinoma,” they wrote.

Today’s top news highlights: ACE inhibitors in COVID patients, fewer AMI admissions, and more
Here are the stories our MDedge editors across specialties think you need to know about today:
Are ACE inhibitors protective in COVID-19?
Older patients with COVID-19 had a lower risk of developing severe illness if they were taking ACE inhibitors, according to a large observational U.S. study. ACE inhibitor use was associated with an almost 40% lower risk for COVID-19 hospitalization for older people enrolled in Medicare Advantage plans. Senior investigator Harlan M. Krumholz, MD, said that while he and his associates think this finding is worthy of further study, “We don’t believe this is enough info to change practice.” The study was published on the MedRxiv preprint server and has not yet been peer reviewed.

AMI: Admissions drop, deaths rise
In Italy, sharp nationwide decreases in hospitalizations for acute myocardial infarctions (AMIs) during the height of COVID-19 were offset by higher mortality for patients who did present. The study counted AMIs at 54 hospitals nationwide for the week of March 12-19, 2020, and compared that with an equivalent week in 2019 – 319 vs. 618 AMIs, respectively, representing a 48% reduction in hospitalizations. Mortality for ST-segment elevation MI cases more than tripled to 14% during the outbreak, compared with 4% in 2019. “The concern is fewer MIs most likely means people are dying at home or presenting later as this study suggests,” commented Martha Gulati, MD, chief of cardiology at the University of Arizona, Phoenix, who was not involved with the study.

Prenatal, postpartum screening for depression falls short
Health care providers fail to ask one in five prenatal patients and one in eight postpartum patients about depression, according to the Centers for Disease Control and Prevention. Researchers analyzed self-reported data on postpartum depressive symptoms collected in 2018 by the Pregnancy Risk Assessment Monitoring System. Mental health conditions play a role in approximately 9% of pregnancy-related deaths and not asking about depression represents “missed opportunities to potentially identify and treat women with depression,” said coauthor Jean Y. Ko, PhD, from the division of reproductive health at the National Center for Chronic Disease Prevention and Health Promotion.

Many clinicians still not asking about postpartum depression
Health care providers fail to ask one in five prenatal patients and one in eight postpartum patients about depression, according to the Centers for Disease Control and Prevention. Although the prevalence of screening has risen in recent years, many women could be suffering in silence.
“[U]ndetected and untreated perinatal depression can have negative health consequences for the mothers and their babies,” said coauthor Jean Y. Ko, PhD, from the division of reproductive health at the National Center for Chronic Disease Prevention and Health Promotion.
Dr. Ko and colleagues reported their findings in an article published in Morbidity and Mortality Weekly Report.
The researchers analyzed self-reported data on postpartum depressive symptoms (PDS) collected in 2018 by the Pregnancy Risk Assessment Monitoring System (PRAMS). Participants were stratified on the basis of location and maternal and infant characteristics, including age, race/ethnicity, and education level. Women who had recently given birth to one or more live infants answered questions about whether they had been screened by health care providers for depression during perinatal visits.
The prevalence of PDS among women from 31 PRAMS sites was 13.2%. States with lower prevalences included Illinois (9.7%), Massachusetts (10.3%), and Wisconsin (10.5%); states with higher prevalences included Mississippi (23.5%), West Virginia (19.4%), and Michigan (16.4%).
Some groups were at higher risk for PDS than others. The prevalence was greater than 20% among women who were aged 19 years or younger, were of American Indian or Alaska Native ethnicity, smoked during the perinatal period, experienced perinatal depression, or whose infant died after birth.
Depressive symptoms were also more common among women who received assistance from the Women, Infants, and Children program; were Medicaid beneficiaries at the time of delivery; smoked cigarettes during the last trimester of pregnancy; breastfed their infants for fewer than 8 weeks; or had experienced intimate partner violence while pregnant or before.
Small rise in screening
Overall, 79.1% of women said a health care provider had inquired about depression during the prenatal period. Prenatal screening for depression was lowest in Puerto Rico (50.7%), Mississippi (69.4%), Utah (69.5%), and Kentucky (69.5%) and was highest in Alaska (90.7%), Minnesota (90.6%), and Maine (90.5%).
Among 22 continuously reporting sites, the prevalence of prenatal depression screening rose significantly from 76.2% in 2016 to 79.3% in 2018 (P < .05) .
“It is unclear what might account for this small increase,” Dr. Ko said. “There may be additional factors, such as women may be becoming more comfortable reporting symptoms of depression. With continued awareness about the need to screen every pregnant and postpartum woman for depression, we can expect things to continue to improve.”
Overall, 90.1% of respondents reported a postpartum visit; of those, 87.4% said a health care provider had asked about depression during that visit.
Screening during the postpartum period was highest in Vermont (96.2%), Minnesota (95.9%), and Maine (95.5%) and was lowest in Puerto Rico (50.7%), New York City (73.1%), and Louisiana (75.0%).
Among the 22 sites that reported continuously, the prevalence of screening for postpartum depression rose significantly from 84.1% to 88.0% (P < .05), “with an average annual percentage point increase of 1.8%,” the authors wrote.
‘Missed opportunities’
“PRAMS responses are reported an average of 4 months postpartum, which suggests persistence of [depressive] symptoms,” the authors wrote.
Dr. Ko said that mental health conditions play a role in approximately 9% of pregnancy-related deaths and that not asking about depression represents “missed opportunities to potentially identify and treat women with depression.” The United States Preventive Services Task Force recommends screening all adults for depression, including women during pregnancy and the postpartum period, she added.
When asked what can be done to improve screening that has not already been tried, Dr. Ko said the CDC is currently evaluating a study called the Program in Support of Moms (PRISM), which “is designed to help obstetrics and gynecology practices address the significant public health issue of depression during and after pregnancy. PRISM aims to close gaps in health care delivery to ensure that women with depression during and after pregnancy receive the best treatment, which can result in improvement in their symptoms.”
Dr. Ko added that the Health Resources and Services Administration has funded seven states to begin “programs to support providers to screen, assess, refer, and treat pregnant and postpartum women for depression and other behavioral health conditions. States can use initiatives like Healthy Start, home visiting, and Title V Maternal and Child Health Services Block Grant programs as levers to improve screening and address maternal depression.
“Screening is just one part of addressing perinatal depression. Health care providers need to refer women to appropriate resources in order to get the proper diagnosis, treatment, and follow-up care for management of depression,” Dr. Ko concluded.
The authors disclosed no relevant financial relationships.

“PRAMS responses are reported an average of 4 months postpartum, which suggests persistence of [depressive] symptoms,” the authors wrote.
Dr. Ko said that mental health conditions play a role in approximately 9% of pregnancy-related deaths and that not asking about depression represents “missed opportunities to potentially identify and treat women with depression.” The United States Preventive Services Task Force recommends screening all adults for depression, including women during pregnancy and the postpartum period, she added.
When asked what can be done to improve screening that has not already been tried, Dr. Ko said the CDC is currently evaluating a study called the Program in Support of Moms (PRISM), which “is designed to help obstetrics and gynecology practices address the significant public health issue of depression during and after pregnancy. PRISM aims to close gaps in health care delivery to ensure that women with depression during and after pregnancy receive the best treatment, which can result in improvement in their symptoms.”
Dr. Ko added that the Health Resources and Services Administration has funded seven states to begin “programs to support providers to screen, assess, refer, and treat pregnant and postpartum women for depression and other behavioral health conditions. States can use initiatives like Healthy Start, home visiting, and Title V Maternal and Child Health Services Block Grant programs as levers to improve screening and address maternal depression.
“Screening is just one part of addressing perinatal depression. Health care providers need to refer women to appropriate resources in order to get the proper diagnosis, treatment, and follow-up care for management of depression,” Dr. Ko concluded.
The authors disclosed no relevant financial relationships.

Extremely preterm infants fare better with corticosteroid and magnesium combo
Children born before 27 weeks’ gestation had lower combined risk of death or severe neurodevelopmental impairment when exposed to antenatal corticosteroids and magnesium sulfate together, compared with exposure of either or neither therapy, according to a prospective observational study published in Obstetrics & Gynecology.
“If there is sufficient time to administer antenatal corticosteroids, there should similarly be sufficient time to administer magnesium sulfate,” wrote Samuel J. Gentle, MD, of the University of Alabama at Birmingham, and colleagues. “Given the lower rate of severe neurodevelopmental impairment or death in children exposed to both antenatal corticosteroids and magnesium sulfate in the present study, compared with those exposed to antenatal corticosteroids alone, increasing the rates of magnesium sulfate exposure through quality improvement or other interventions may improve infant outcomes.”
Although previous randomized controlled trials had shown neurologic benefits of each therapy independently in preterm children, few data exist on extremely preterm children, the authors noted. They also pointed out differences in the findings when they analyzed neurodevelopmental outcomes and death separately.
“Whereas exposure to both therapies was associated with a lower rate of death, exposure to magnesium sulfate in addition to antenatal corticosteroids was not associated with a lower rate of severe neurodevelopmental impairment or components of severe neurodevelopmental impairment including Bayley scores, bilateral hearing impairment, and cerebral palsy,” Dr Gentle and his coauthors wrote.
The researchers used prospectively collected data from the Eunice Kennedy Shriver National Institute of Child Health and Human Development Neonatal Research Network Generic Database to track 3,093 children born extremely preterm – from 22 weeks 0 days to 26 weeks 6 days – during 2011-2014.
The researchers compared outcomes of death or severe neurodevelopmental impairment when the children were 18-26 months of corrected age based on whether they had been exposed to antenatal corticosteroids alone (betamethasone or dexamethasone) or antenatal corticosteroids in addition to magnesium sulfate. Severe neurodevelopmental impairment included “severe cerebral palsy, motor or cognitive composite score less than 70 on the Bayley-III exam, bilateral blindness, or bilateral severe functional hearing impairment with or without amplification.”
The researchers also looked at severe neurodevelopmental impairment and death among children with only magnesium sulfate exposure or with no exposure to steroids or magnesium.
In the study population, 73% of infants had been exposed to both therapies, 16% had been exposed to only corticosteroids, 3% to only magnesium sulfate, and 8% to neither therapy.
“Importantly, a larger proportion of mothers unexposed to either therapy, compared with both therapies, received high school or less education or had no maternal private health insurance which may suggest health inequity as a driver for antenatal therapy exposure rates,” Dr. Gentle and associates noted.
Children whose mothers received corticosteroids and magnesium had a 27% lower risk of severe neurodevelopmental impairment or death, compared with those whose mothers only received corticosteroids (adjusted odds ratio, 0.73). Just over a third of children exposed to both interventions (36%) had severe neurodevelopmental impairment or died, compared with 44% of those exposed only to steroids.
Similarly, corticosteroids and magnesium together were associated with approximately half the risk of death or severe neurodevelopmental impairment, compared with magnesium alone (aOR, 0.49) and 34% lower risk, compared with neither therapy (aOR 0.66).
When the researchers uncoupled the outcomes, severe neurodevelopmental impairment rates were similar among all exposure groups, but rates of death were lower among those who received both therapies than among those who received just one or neither therapy.
“The therapeutic mechanism for neuroprotection in children exposed to magnesium sulfate is unclear but may result from neuronal stabilization or anti-inflammatory properties,” Dr. Gentle and colleagues said.
They also compared rates in the exposure groups of grade 3-4 intracranial hemorrhage, which has been linked to poor neurodevelopmental outcomes in extremely preterm children.
“The rate of grade 3-4 intracranial hemorrhage did not differ between children exposed to both antenatal corticosteroids and magnesium sulfate and those exposed to antenatal corticosteroids alone,” they said. “These findings further support data from randomized controlled trials showing benefit for antenatal corticosteroids but not for magnesium sulfate.”
They further noted a Cochrane Review that found significantly reduced risk of severe or any intracranial hemorrhage among children exposed to antenatal corticosteroids. No similar reduction in intracranial hemorrhage occurred in a separate Cochrane Review of antenatal magnesium sulfate trials.
The research was funded by the National Institutes of Health, Eunice Kennedy Shriver National Institute of Child Health and Human Development, and the National Center for Advancing Translational Sciences.

U.S. fertility rates fall to record lows
and birth rates for women under age 30 fell to record lows, according to the National Center for Health Statistics.
To be exact – at least as exact as is possible from these provisional data – there were 3,745,540 births in the United States last year. That’s down about 1% from 2018 and is the lowest number of births since 1985, Brady E. Hamilton, PhD, and associates at the NCHS said in a rapid release report.
As births go, so goes the general fertility rate. A 2% decrease from 2018 to 2019 left the fertility rate at its lowest point ever: 58.2 births per 1,000 women aged 15-44 years, compared with 59.1 per 1,000 in 2018, the investigators said, based on data from the National Vital Statistics System.
The total fertility rate – defined as “the number of births that a hypothetical group of 1,000 women would have over their lifetimes, based on the age-specific birth rate in a given year” – also reached a record low of 1,705 births per 1,000 women last year after falling 1% from 2018, they reported.
The falling birth rates did not include women over age 35. The birth rate among women aged 40-44 increased by 2% from 2018, as it reached 12.0 births per 1,000 in 2019. “The rate for this age group has risen almost continuously since 1985 by an average of 3% per year,” Dr. Hamilton and associates wrote.
The birth rate for women aged 30-34 years, 98.3 per 1,000, was down 1% from 2018 but was still the highest for any age category. Among younger women, rates all dropped to record lows: 16.6 (ages 15-19), 66.6 (ages 20-24), and 93.7 (ages 25-29), they said.
Preterm birth rates, on the other hand, rose for the fifth year in a row. The rate for 2019, 10.23% of all births, represents an increase of 2% over 2018 and is “the highest level reported in more than a decade,” the investigators noted.
