Declines in infant mortality tempered by disparities
Age-adjusted infant mortality dropped 11% from 2000 to 2017 in the United States, but the even larger decline for infants born to black women still left a death rate more than twice as high as those of white or Hispanic infants, according to a new analysis from the National Center for Health Statistics.
while the crude mortality rate fell 16% from 6.89 to 5.79, reported Anne K. Driscoll, PhD, and Danielle M. Ely, PhD, of the NCHS.
Over that same time period, age-adjusted infant mortality for births to black women went from 13.59 per 1,000 to 11.19, a drop of 18%. By comparison, age-adjusted mortality declined 7% from 5.59 per 1,000 for infants born to Hispanic women to 5.21 in 2017, they said in a National Vital Statistics Report.
Changes in maternal age distribution had an important effect on infant mortality. Women aged under 25 years, who have higher mortality rates, were less likely to give birth in 2017 than in 2000, and women aged 30-39 years, who have the lowest rates, made up a larger share of births in 2017, they pointed out.
It was, however, changes in age-specific mortality rates (ASMRs) that had the largest influence on the overall drop in the crude mortality rate, accounting for about two-thirds of the overall decline, the NCHS researchers said, noting that the effect varied by race and Hispanic origin.
Births to non-Hispanic white women mirrored the national situation: Approximately two-thirds (68.7%) of the decrease in infant mortality came from changes in ASMRs and one-third (31.3%) from changes in maternal age distribution. Among non-Hispanic black women, the distribution was 95.2% ASMRs and 4.8% age distribution, Dr. Driscoll and Dr. Ely reported based on data from the National Vital Statistics System.
The disparity between the two trends went even further for infants born to Hispanic women. Changes in ASMRs were responsible for 133.7% of the overall change in crude mortality versus –33.7% for changes in maternal age distribution. “If no changes occurred in the ASMRs, the changes in the maternal age distribution would have resulted in a higher mortality rate in 2017,” they explained.
The declines in the ASMRs may be related to incremental improved survival of preterm and low-birthweight infants in certain groups. “While little or no progress has been made to lower [these] two key risk factors for poor birth outcomes, progress has been made in lowering the mortality rates of at-risk infants across maternal age and race and Hispanic origin, resulting in lower ASMRs for all age groups,” the investigators suggested.
It also is possible that “changes in other factors, such as maternal education and cigarette smoking during pregnancy, may have indirectly resulted in declining ASMRs for all age groups over time,” they added.

Migraine is often a deciding factor in pregnancy planning
new research shows. Results from a multicenter study of more than 600 women showed that, among participants with migraine, those who were younger, had menstrual migraine, or had chronic migraine were more likely to decide to not become pregnant.
Although women with migraine who avoided pregnancy believed their migraines would worsen during pregnancy or make their pregnancy difficult, previous observational research indicates that migraine often improves during pregnancy.
“Women who avoided pregnancy due to migraine were most concerned that migraine would make raising a child difficult, that the migraine medications they take would have a negative impact on their child’s development, and that their migraine pattern would worsen during or just after pregnancy,” said study investigator Ryotaro Ishii, MD, PhD, a visiting scientist at Mayo Clinic in Phoenix, Arizona.
The findings were presented at the virtual annual meeting of the American Headache Society.
Plans for the future
There is a paucity of research on the effects of migraine on pregnancy planning, the researchers noted. The few studies that have investigated this issue have focused on women’s previous family planning decisions and experience rather than on plans for the future, the researchers noted.
To evaluate how migraine in women influences pregnancy planning, the investigators analyzed data from the American Registry for Migraine Research (ARMR). The registry, which was established by the American Migraine Foundation, collects clinical data about individuals with migraine and other headache disorders from multiple centers.
Participants eligible for the current analysis were women who had been diagnosed with migraine on the basis of the International Classification of Headache Disorders–3 criteria. All completed the ARMR questionnaire between February 2016 and September 2019. The investigators excluded patients with trigeminal autonomic cephalalgia, secondary headache, painful cranial neuropathies, other facial pain, and other headaches.
They identified 895 eligible women with migraine. Of these, 607 completed the pregnancy question. Among those participants, 121 women (19.9%) reported that migraine was a factor in their decision to not become pregnant. Of this group, 70 (11.5%) reported that migraine was a “significant” factor in deciding to not have children, and 8.4% said it was “somewhat” of a factor. The remainder of the cohort (479) reported that migraine had no influence on their pregnancy plans.
There were no between-group differences by race, marital status, employment, or income. This finding suggests that sociodemographic differences “have less impact on pregnancy planning than migraine-specific characteristics like headache frequency and experience with having migraine attacks triggered by menstruation,” Dr. Ishii said.
“Substantial burden”
Not surprisingly, women who avoided pregnancy had fewer children than the rest of the sample. About 60% of those who made the decision to not become pregnant had no children, and 72% had not been pregnant since they began experiencing migraine.
Compared with women who reported that migraine had no influence on their pregnancy plans, those who avoided pregnancy were more likely to have chronic migraine at 81.8% versus 70.2%. They were also more likely to have menstrual migraine at 4.1% versus 1%. In addition, women who decided to not have children because of migraine were significantly younger at an average age of 37.5 versus 47.2 years.
The number of days with headache per 3-month interval was 53.9 among women who avoided pregnancy versus 42.5 among the other women. The Migraine Disability Assessment score was also higher for women who avoided pregnancy (132.5) than for it was the other women (91.7), indicating more severe disability.
In addition, more of the women who avoided pregnancy had a history of depression (48.8%) compared with the other women (37.7%). The average score on the Patient Health Questionnaire–4 was higher among women who avoided pregnancy (4.0) than among other women (3.1), which indicates greater anxiety or depression. Among women who avoided pregnancy, 72.5% believed their migraine would worsen during pregnancy, and 68.3% believed that migraine would make pregnancy very difficult.
“Clinicians need to recognize that migraine often has a substantial burden on multiple aspects of life, including one’s plans for having children,” Dr. Ishii said.
“Clinicians should educate their patients who are considering pregnancy about the most likely course of migraine during pregnancy, migraine treatment during pregnancy, and the potential impacts of migraine and its treatment on pregnancy outcomes,” he added.
More education needed
Commenting on the study, Susan Hutchinson, MD, director of the Orange County Migraine and Headache Center, Irvine, California, said that not knowing how pregnancy is going to affect patients’ migraines can be “very scary” for women. In addition, patients often wonder what migraine treatments they can safely take once they do become pregnant, said Dr. Hutchinson, who was not involved in the research.
She noted that advantages of the ARMR data are that they are derived from a multicenter study and that migraine diagnoses were made by a headache specialist. A potential limitation of the study is that the population may not reflect outcomes of the millions of women who have migraine and become pregnant but never see a specialist.
“These findings show that more education is needed,” Dr. Hutchinson said.
Most women, especially those who have migraine without aura, note improvement with migraine during pregnancy, primarily because of the high, steady levels of estradiol, especially in the second and third trimesters, she said. In light of this, neurologists should reassure women that migraine is not a contraindication to pregnancy, she added.
There is also a need for additional research to assess how past experience with migraine and pregnancy influences a woman’s comfort level with additional pregnancies. Studies as to which treatments are safest for acute and preventive treatment of migraine during prepregnancy, pregnancy, and lactation are also needed, Dr. Hutchinson noted.
“If women knew they had treatment options that were evidence-based, they might be much more comfortable contemplating a pregnancy,” she said.
Dr. Ishii and Dr. Hutchinson have disclosed no relevant financial relationships.

Zoledronic acid fails to impact abdominal aortic calcification
A single yearly dose of zoledronic acid had no impact on the progression of abdominal aortic calcification in postmenopausal women with osteoporosis, based on data from 502 women.
Although bisphosphonates have been shown to reduce the formation and progression of vascular calcification in animal studies, the impact on aortic calcification in humans has not been studied, wrote Guoqi Cai, PhD, of the University of Tasmania, Australia, and colleagues.
In a post hoc analysis published in Osteoporosis International, the researchers reviewed data from the HORIZON Pivotal Fracture trial of women with osteoporosis.
The study population included 234 postmenopausal women with osteoporosis who received an annual infusion of 5 mg zoledronic acid (ZA) and 268 who received a placebo. The mean age of the women was 72.5 years. Overall, abdominal aortic calcification (AAC) was present in 292 women (58%) at baseline, defined as an AAC score greater than 0, and AAC scores were similar between the intervention and placebo groups.
Over 3 years, AAC progressed similarly between the ZA and placebo groups (29% and 31%, respectively). Progression was defined as an increase in AAC score, which was measured by comparing spinal x-rays at baseline and after 3 years. In a subgroup analysis, progression of AAC was similar between the ZA and placebo groups with and without baseline AAC.
“The lack of effect on the progression of vascular calcification with zoledronic acid treatment in this study does not rule out a potential role of bisphosphonates in reducing cardiovascular mortality mediated through other mechanisms,” the researchers noted.
No correlation appeared between change in AAC score and change in bone mineral density at the total hip and femoral neck during the study period in any of the groups.
The study findings were limited by several factors including the post hoc analysis, potential lack of sensitivity of the AAC-8 scale in measuring small AAC changes, and homogenous study population, the researchers noted.
However, the study is the first to examine the impact of zoledronic acid on aortic calcification in humans, and was strengthened by the randomized design, the researchers said. Although other studies on the impact of bisphosphonates on vascular calcification have been inconsistent, the “finding that zoledronic acid was not protective against vascular calcification agrees with previous trials of nitrogen-containing bisphosphonates conducted in postmenopausal women with osteoporosis,” as well as chronic kidney disease patients and renal transplant patients, they said.
“Thus, our findings do not support the use of zoledronic acid for the treatment of vascular calcification,” they concluded.
The study was supported by Novartis. Dr. Cai had no financial conflicts to disclose.

Novel SERD, LSZ102, shows promise for pretreated ER+ breast cancer
The oral selective estrogen receptor degrader (SERD) LSZ102 plus either ribociclib or alpelisib shows manageable safety and encouraging clinical activity in heavily pretreated estrogen receptor (ER)–positive breast cancer patients who progressed after prior endocrine therapy, according to interim results of an open-label phase 1/1b study.
The effects seen in the study, which is the first to report on an oral SERD in combination with both CDK4/6 and PI3Ka inhibitors, occurred regardless of ESR1 and PIK3CA mutations, said Komal Jhaveri, MD, of Memorial Sloan Kettering Cancer Center in New York.
Dr. Jhaveri reported the results at the European Society of Medical Oncology: Breast Cancer virtual meeting.
The overall response rate (ORR) among 78 patients enrolled in an LSZ102 monotherapy arm (arm A) was 1.3%, and the progression-free survival (PFS) was 1.8 months. The clinical benefit rate (CBR) was 9.1%.
Among 76 patients enrolled in an LSZ102+ribociclib arm (arm B), the ORR was 15.8%, the PFS was 6.2 months, and the CBR was 35.5%.
Among the 39 patients enrolled in an LSZ102+alpelisib arm (arm C), the ORR was 5.4%, the PFS was 3.5 months, and the CBR was 18.9%.
After the data cutoff, one additional partial response (PR) was reported in arm C, Dr. Jhaveri said, noting that two of three confirmed responses were in known PIKC3A-mutant patients.
Study participants were aged 18 years and older with a confirmed diagnosis of ER-positive breast cancer and good performance status, as well as evidence of progression after endocrine therapy for metastatic disease or evidence of progression while on therapy or within 12 months from the end of adjuvant therapy.
“For all arms, prior fulvestrant, CDK46 inhibitor, or chemotherapy were allowed. For arm C, patients with or without PIK3C were eligible, and no prior treatment with PIK3, mTOR, or AKT inhibitors was allowed,” Dr. Jhaveri said.
Dosing in the LSZ102 monotherapy arm ranged from 200 to 900 mg. Arm B patients received LSZ102 at doses of 200-600 mg and ribociclib at doses of 200-600 mg. Both continuous ribociclib and 3 weeks on/1 week off dosing were evaluated. Arm C patients received LSZ102 at doses of 300-450 mg and alpelisib at 200-300 mg.
The recommended expansion doses were 450 mg daily of LSZ102 for arm A and 450 mg LSZ102 with 400 mg of daily ribociclib for arm B. For arm C, they were 300 mg LSZ102 with 250 mg of alpelisib daily.
Of note, two of three patients with a PR in arm C had received 300 mg LSZ102 and 300 mg alpelisib, Dr. Jhaveri said.
Arm A and arm B results were presented at the San Antonio Breast Cancer Symposium in 2018 and 2019, respectively. The current report updates those findings and presents arm C data for the first time, Dr. Jhaveri said.
LSZ102 was relatively well-tolerated as a single agent and in combination with ribociclib and alpelisib, according to Dr. Jhaveri. The most frequent adverse events were gastrointestinal toxicities, including nausea, vomiting, diarrhea, and decreased appetite, which occurred across all arms.
Neutropenia and aspartate aminotransferase abnormalities, including grade 3 cases, were reported in arm B and were most likely driven by the ribociclib, Dr. Jhaveri said. Grade 3 hypoglycemia and skin rash commonly occurred in arm C, most likely driven by the alpelisib.
Five dose-limiting toxicities occurred in four patients in arm A, three occurred in two patients in arm B, and seven occurred in seven patients in arm C.
Paired biopsies collected at the time of screening and at day 15 of cycle 1 showed consistent down-regulation of ER protein levels across arms.
“No substantial dose-dependent down-regulation of the ER was observed with increasing doses of LSZ,” Dr. Jhaveri said.
Circulating tumor DNA (ctDNA) analysis showed that the dominant mutations across the arms were ESR1, PIK3CA, and TP53. These were not shown to correlate with response and were not enriched upon progression in patients with matched baseline and end-of-treatment samples, she noted.
An exploratory analysis, conducted in “a preliminary attempt to correlate clinical activity with specific mutations,” showed that, in arms B and C, respectively, ORR, CBR, and PFS weren’t correlated with the presence or absence of ESR1 and PIK3CA mutations, respectively, or the absence of detectable ctDNA from baseline samples, Dr. Jhaveri said.
“While numerically higher responses and better CBR were seen in patients with undetectable ctDNA at baseline, no statistically significant difference in any of these outcomes was observed in arms B and C,” she said.
In arm C, the numbers were small at the time of data cutoff, but incoming data suggest relatively enhanced activity of the LSZ102 plus alpelisib combination in PIKC3A-mutant patients, she noted.
“We know that inhibiting ER signaling is the mainstay of treatment for ER-positive breast cancer,” Dr. Jhaveri explained, adding that aromatase inhibitors, estrogen receptor modulators, and SERDs are important classes of antiestrogenic agents, but fulvestrant is the only approved SERD. These are effective, but many patients develop resistance, she said.
“Proposed mechanisms for endocrine resistance include activation of the cell-cycle and cell-survival signaling pathways, or of the PI3K-AKT-mTOR pathway,” Dr. Jhaveri said. “To that end, ribociclib, a CDK46 inhibitor plus fulvestrant improved survival compared to fulvestrant alone in patients with ER-positive metastatic breast cancer.”
More recently, the PI3K inhibitor alpelisib plus fulvestrant also nearly doubled PFS vs. fulvestrant alone in PIKC3A-mutant, ER-positive metastatic breast cancer, which led to the approval of the combination in the United States.
Another mechanism of endocrine resistance includes acquisition of activating mutations in the estrogen receptor gene itself that allow tumors to survive and proliferate without depending on estrogen.
EGFR mutations appear to predict resistance to aromatase inhibitor therapies, but not outcomes in patients treated with fulvestrant. However, fulvestrant, which is delivered by intramuscular injection, has its own limitations, Dr. Jhaveri said.
“LSZ102 is a novel SERD that could achieve higher exposure than fulvestrant, leading to enhanced efficacy,” she said, noting that it was shown in preclinical models to have activity and to be synergistic in combination with ribociclib and alpelisib, forming the basis for the current study.
Invited discussant, Saverio Cinieri, MD, of Ospedale Antonio Perrino, Brindisi, Italy, said the study “elegantly demonstrated that estrogen receptor protein is down-regulated by LSZ102; [that] the genomic landscape of heavily pretreated patients is dominated by mutations in ESR1, PIK3CA, and TP53; [that] common mutations do not correlate with response and are not enriched on progression; [and that] ctDNA analysis at baseline shows similar outcomes with LSZ plus ribociclib or alpelisib, regardless of mutational status.”
LSZ102 is one of four new-generation SERDs in early-phase studies, he said, concluding that “in the COVID-19 era, the use of oral therapies will be even more necessary to limit access to the hospital.”
Dr. Cinieri also said that overcoming the limitations “of a molecule like the intramuscularly administered fulvestrant goes in this direction,” and that “the clinical efficacy and the biomolecular profile of LSZ102 seems to be able to meet these real needs.”
This study was funded by Novartis. Dr. Jhaveri reported advisory and consultancy roles and/or research grants or other funding to her institution from Novartis, ADC Therapeutics, Pfizer, and numerous other pharmaceutical and biotechnology companies. Dr. Cinieri reported relationships with Lily Oncology, Pfizer, Roche, AstraZeneca, Amgen, Novartis, including honoraria, grant and research support to his institution, advisory board participation, and scientific meeting support.

FDA approves in-home breast cancer treatment
Advantageous for infusion centers?
The Food and Drug Administration approved a combination of pertuzumab (Perjeta, Genentech/Roche), trastuzumab (Herceptin, Genentech/Roche) and hyaluronidase (Phesgo, Genentech/Roche) that is administered subcutaneously – rather than intravenously – for the treatment of early and metastatic HER2-positive breast cancers.
Phesgo is initially used in combination with chemotherapy at an infusion center but could continue to be administered in a patient’s home by a qualified health care professional once chemotherapy is complete, according to the FDA.
Administration takes approximately 8 minutes for the initial loading dose and approximately 5 minutes for maintenance doses, according to a Genentech press statement. This compares favorably with the 150 minutes needed for the combined loading dose of intravenous pertuzumab and trastuzumab, and the 60-150 minutes for intravenous maintenance infusions, the company said.
“Currently, most patients with HER2-positive breast cancer receive trastuzumab and pertuzumab at infusion centers. With a new administration route, Phesgo offers an outpatient option for patients to receive trastuzumab and pertuzumab,” said Richard Pazdur, MD, director of the FDA’s Oncology Center of Excellence and acting director of the Office of Oncologic Diseases in the FDA’s Center for Drug Evaluation and Research, in an agency press release.
“The fixed-dose combination of trastuzumab and pertuzumab offers a simpler, faster, and easier treatment experience for patients with HER2-positive breast cancer,” said Antoinette Tan, MD, MHSc, chief of breast medical oncology at Levine Cancer Institute, Charlotte, N.C., in the company statement.
Dr. Tan also said that home administration “can be advantageous for patients and infusion centers.”
However, in April, the Community Oncology Alliance strenuously objected to this type of treatment in a patient’s home, as reported by Medscape Medical News.
The group, which represents U.S. community-based practices, said it “fundamentally opposes home infusion of chemotherapy, cancer immunotherapy, and cancer treatment supportive drugs because of serious patient safety concerns.”
The FDA’s approval was based on the results of the pivotal phase 3 FeDeriCa trial, a noninferiority study in patients with HER2-positive early breast cancer, which demonstrated that the new product had comparable efficacy and safety as intravenous pertuzumab and intravenous trastuzumab.
In terms of efficacy, the subcutaneous product demonstrated noninferior plasma levels of pertuzumab, which was the primary endpoint, when compared with IV administration of pertuzumab.
Safety was comparable between the two approaches, with no new safety signals using the subcutaneous delivery method, including no “meaningful difference” in cardiac toxicity, according to Genentech. However, there were more administration-related reactions with the new product. The most common adverse events in both groups were alopecia, nausea, diarrhea, and anemia.
The new product uses a drug delivery technology (Enhanze, Halozyme Therapeutics) that employs a proprietary enzyme that temporarily degrades hyaluronan, a glycosaminoglycan or chain of natural sugars in the body, to facilitate the dispersion and absorption of injected therapeutic drugs, according to Genentech.
In May, at the European Society for Medical Oncology Breast Cancer Virtual Meeting 2020, investigators of the phase 2 PHranceSCa study reported that “more than 80%” of patients preferred subcutaneous to intravenous administration of pertuzumab and trastuzumab.

The FDA’s approval was based on the results of the pivotal phase 3 FeDeriCa trial, a noninferiority study in patients with HER2-positive early breast cancer, which demonstrated that the new product had comparable efficacy and safety as intravenous pertuzumab and intravenous trastuzumab.
In terms of efficacy, the subcutaneous product demonstrated noninferior plasma levels of pertuzumab, which was the primary endpoint, when compared with IV administration of pertuzumab.
Safety was comparable between the two approaches, with no new safety signals using the subcutaneous delivery method, including no “meaningful difference” in cardiac toxicity, according to Genentech. However, there were more administration-related reactions with the new product. The most common adverse events in both groups were alopecia, nausea, diarrhea, and anemia.
The new product uses a drug delivery technology (Enhanze, Halozyme Therapeutics) that employs a proprietary enzyme that temporarily degrades hyaluronan, a glycosaminoglycan or chain of natural sugars in the body, to facilitate the dispersion and absorption of injected therapeutic drugs, according to Genentech.
In May, at the European Society for Medical Oncology Breast Cancer Virtual Meeting 2020, investigators of the phase 2 PHranceSCa study reported that “more than 80%” of patients preferred subcutaneous to intravenous administration of pertuzumab and trastuzumab.

Subclinical hypothyroidism appears common in women with miscarriage
according to a prospective observational study published in the Journal of Clinical Endocrinology & Metabolism.
Whether asymptomatic patients should be screened for mild subclinical hypothyroidism (SCH) or thyroid peroxidase antibodies (TPOAb) remains an open question, however. “In the absence of evidence of benefit with LT4 [levothyroxine] treatment and possible suggestion of harm ... we pose the question of whether screening should be performed at all in asymptomatic individuals,” wrote Rima K. Dhillon-Smith, MBChB, PhD, of the University of Birmingham (England), and colleagues. “Large randomized trials are needed to establish if preconception LT4 treatment of mild SCH with or without TPOAb positivity is beneficial. If treatment is found to be beneficial, this study presents the prevalence of thyroid disorders that can be expected.”
Subclinical hypothyroidism may represent an early stage of thyroid dysfunction. The condition has been associated with subfertility, miscarriage, preterm birth, preeclampsia, and perinatal mortality. Thyroid peroxidase antibodies also have been associated with adverse pregnancy outcomes, and their presence increases the risk of subclinical and overt thyroid disease in pregnancy. “There is international agreement on the treatment of overt thyroid disease,” the researchers wrote. “However, the treatment strategies for SCH or TPOAb preconception and antenatally are debated.”
The Thyroid Antibodies and Levothyroxine (TABLET) trial, to which the present study was linked, “found no improvement in live birth or any secondary pregnancy or neonatal outcomes in euthyroid women with TPOAb taking 50 mcg of LT4, compared with placebo.”
To examine various thyroid-stimulating hormone (TSH) cutoff levels for diagnosing subclinical thyroid disease in preconception asymptomatic women with a history of miscarriage or subfertility, Dr. Dhillon-Smith and colleagues conducted a prospective, observational cohort study at 49 hospitals in the United Kingdom. The study included more than 19,200 patients between November 2011 and January 2016. Participants were aged 16-41 years, had a history of miscarriage or subfertility, and were actively trying to get pregnant.
Using accepted reference ranges, the investigators identified undiagnosed overt hypothyroidism in 0.2%, overt hyperthyroidism in 0.3%, severe SCH (TSH greater than 10 mIU/L) in 0.2%, and SCH (TSH greater than 4.5 mIU/L) in 2.4%. “Lowering the upper limit of TSH to 2.5 mIU/L, as is the recommendation by international societies for ‘high-risk’ women,” such as those with recurrent pregnancy loss or those undergoing assisted reproductive technology, “would class 16%-20% of women as subclinically hypothyroid,” the authors reported.
The prevalence of TPOAb was 9.5%, and the presence of these antibodies “was the factor associated most significantly with any degree of thyroid dysfunction, after adjustment for confounders,” Dr. Dhillon-Smith and colleagues wrote. Multiple regression analyses found that the likelihood of subclinical hypothyroidism (TSH greater than 4.5 mIU/L) was increased for participants with a body mass index of 35 kg/m2 or greater (adjusted odds ratio, 1.71) and Asian ethnicity (aOR, 1.76).
The U.K. rates of thyroid dysfunction appear to be lower than rates in the United States, and it is unclear why higher body mass index and Asian ethnicity were independently associated with higher TSH concentrations, commented Mark P. Trolice, MD, director of Fertility CARE: The IVF Center in Winter Park, Fla., and professor of obstetrics and gynecology at the University of Central Florida, Orlando.
Women with a history of three or more miscarriages or subfertility were not more likely to be TPOAb positive, compared with women with one or two previous miscarriages, which “underscores the evidence that a recurrent pregnancy loss evaluation yields similar diagnostic findings at two versus three or more losses,” Dr. Trolice said.
According to the American Society for Reproductive Medicine, it is reasonable to test infertile women trying to conceive and to treat SCH with levothyroxine to maintain a TSH within the normal range. Women who have TSH greater than 2.5 mIU/L and/or are TPOAb positive can be considered for treatment with levothyroxine.
The Endocrine Society recommends levothyroxine treatment in women with SCH, especially if they are TPOAb positive.
An American Thyroid Association guideline recommends that subclinically hypothyroid women undergoing in vitro fertilization or intracytoplasmic sperm injection be treated with levothyroxine. A 2019 Cochrane Database review, however, found that low-quality evidence precludes clear conclusions.
“While thyroid autoimmunity has been associated with increased miscarriage, preterm births, and lower live birth rates, the confusion lies in which preconception women to test, when to obtain testing, and how to manage nonovert thyroid disease,” said Dr. Trolice, who is a member of the Ob.Gyn. News editorial advisory board.
The observational study was linked to the TABLET trial, which was funded by the National Institute for Health Research. The researchers had no relevant conflicts of interest.

Daily Recap: Transgender patients turn to DIY treatments; ACIP plans priority vaccine groups
Here are the stories our MDedge editors across specialties think you need to know about today:
Ignored by doctors, transgender patients turn to DIY treatments
Without access to quality medical care, trans people around the world are seeking hormones from friends or through illegal online markets, even when the cost exceeds what it would through insurance. Although rare, others are resorting to self-surgery by cutting off their own penis and testicles or breasts.
Even with a doctor’s oversight, the health risks of transgender hormone therapy remain unclear, but without formal medical care, the do-it-yourself transition may be downright dangerous. To minimize these risks, some experts suggest health care reforms such as making it easier for primary care physicians to assess trans patients and prescribe hormones or creating specialized clinics where doctors prescribe hormones on demand.
Treating gender dysphoria should be just like treating a patient for any other condition. “It wouldn't be acceptable for someone to come into a primary care provider’s office with diabetes” and for the doctor to say “‘I can't actually treat you. Please leave,’” Zil Goldstein, associate medical director for transgender and gender non-binary health at the Callen-Lorde Community Health Center in New York City. Primary care providers need to see transgender care, she adds, “as a regular part of their practice.” Read more.
ACIP plans priority groups in advance of COVID-19 vaccine
Early plans for prioritizing vaccination when a COVID-19 vaccine becomes available include placing critical health care workers in the first tier, according to Sarah Mbaeyi, MD, MPH, of the CDC’s National Center for Immunization and Respiratory Diseases.
A COVID-19 vaccine work group is developing strategies and identifying priority groups for vaccination to help inform discussions about the use of COVID-19 vaccines, Dr. Mbaeyi said at a virtual meeting of the CDC’s Advisory Committee on Immunization Practices.
Based on current information, the work group has proposed that vaccine priority be given to health care personnel, essential workers, adults aged 65 years and older, long-term care facility residents, and persons with high-risk medical conditions.
Among these groups “a subset of critical health care and other workers should receive initial doses,” Dr. Mbaeyi said. Read more.
‘Nietzsche was wrong’: Past stressors do not create psychological resilience.
The famous quote from the German philosopher Friedrich Nietzsche, “That which does not kill us makes us stronger,” may not be true after all – at least when it comes to mental health.
Results of a new study show that individuals who have a history of a stressful life events are more likely to develop PTSD and/or major depressive disorder (MDD) following a major natural disaster than their counterparts who do not have such a history.
The investigation of more than a thousand Chilean residents – all of whom experienced one of the most powerful earthquakes in the country’s history – showed that the odds of developing postdisaster PTSD or MDD increased according to the number of predisaster stressors participants had experienced.
“At the clinical level, these findings help the clinician know which patients are more likely to need more intensive services,” said Stephen L. Buka, PhD. “And the more trauma and hardship they’ve experienced, the more attention they need and the less likely they’re going to be able to cope and manage on their own.” Read more.
High-impact training can build bone in older women
Older adults, particularly postmenopausal women, are often advised to pursue low-impact, low-intensity exercise as a way to preserve joint health, but that approach might actually contribute to a decline in bone mineral density, researchers report.
Concerns about falls and fracture risk have led many clinicians to advise against higher-impact activities, like jumping, but that is exactly the type of activity that improves bone density and physical function, said Belinda Beck, PhD, professor at the Griffith University School of Allied Health Sciences in Southport, Australia. But new findings show that high-intensity resistance and impact training was a safe and effective way to improve bone mass.
“Once women hit 60, they’re somehow regarded as frail, but that becomes a self-fulfilling prophecy when we take this kinder, gentler approach to exercise,” said Vanessa Yingling, PhD. Read more.

Concerns about falls and fracture risk have led many clinicians to advise against higher-impact activities, like jumping, but that is exactly the type of activity that improves bone density and physical function, said Belinda Beck, PhD, professor at the Griffith University School of Allied Health Sciences in Southport, Australia.
“There has always been a quandary in terms of pursuing research on this,” she said in an interview. “We know from animal studies that bone only responds to high-intensity activity, but we worry about advising that for people with low bone mass, so instead we give them medications.”
“But not everyone likes to go on meds, they’re not 100% effective, and they’re not free of side effects,” said Beck, who is also the owner and director of The Bone Clinic in Brisbane, Australia.
In 2014, to assess whether high-intensity resistance and impact training (HiRIT) was a safe and effective way to improve bone mass, Beck and her colleagues conducted the LIFTMOR study of 101 postmenopausal women. The researchers showed that bone mineral density in the lumbar spine and femoral neck regions and functional performance measures were significantly better in the 49 participants randomized to HiRIT for 8 months than in the 52 randomized to low-intensity training.
Three years after the completion of LIFTMOR, the researchers looked at bone mineral density in 23 women from the HiRIT group in their retrospective observational study, the results of which were presented at the virtual American College of Sports Medicine 2020 Annual Meeting.
Ongoing gains were significantly better for the seven participants who continued with HiRIT (at least 25% compliance) than for the 16 who did not when looking at both bone mineral density of the lumbar spine (8.63% vs. 2.18%; P = .042) and femoral neck (3.67% vs. 2.85%; P = 0.14).
However, the women who discontinued HiRIT after 8 months maintained the gains in bone mineral density that they had achieved 3 years earlier.
Functional outcomes in the women who continued HiRIT were better than those in the women who did not, but the differences were not significant.
“The takeaway here is that this type of exercise appears to be a highly effective therapy to reduce risk of osteoporotic fracture, since it improves bone mass,” Beck said.
Jump more, lose less bone density
Given the widespread reluctance to suggest HiRIT-type activity to those with low bone mass, this research is significant, said Vanessa Yingling, PhD, from the Department of Kinesiology at California State University, East Bay.
“Once women hit 60, they’re somehow regarded as frail, but that becomes a self-fulfilling prophecy when we take this kinder, gentler approach to exercise,” Yingling said in an interview. “Building bone density in older adults is important, but maintaining current bone density is just as crucial. Without high-impact activity, we are likely to see decelerating density at a faster rate.”
The other key to the recent research is the functional testing, Yingling added. In addition to bone density measures, high-intensity activity can improve mobility and muscle strength, as the study noted.
This type of activity can be done in shorter bursts, making these workouts more efficient, she explained. For example, a Tabata high-intensity interval training session usually takes about 10 minutes, warm-up and cool-down included.
“A HiRIT workout even once or twice a week would likely improve function, strength, and bone density maintenance,” Beck said. “The result of that would be better fall prevention and potentially less medication usage for BMD issues.”
Both men and women can benefit from a HiRIT workout, Beck and Yingling said. Initially, supervision by a knowledgeable trainer or physical therapist is ideal, they added.

Ongoing gains were significantly better for the seven participants who continued with HiRIT (at least 25% compliance) than for the 16 who did not when looking at both bone mineral density of the lumbar spine (8.63% vs. 2.18%; P = .042) and femoral neck (3.67% vs. 2.85%; P = 0.14).
However, the women who discontinued HiRIT after 8 months maintained the gains in bone mineral density that they had achieved 3 years earlier.
Functional outcomes in the women who continued HiRIT were better than those in the women who did not, but the differences were not significant.
“The takeaway here is that this type of exercise appears to be a highly effective therapy to reduce risk of osteoporotic fracture, since it improves bone mass,” Beck said.
Jump more, lose less bone density
Given the widespread reluctance to suggest HiRIT-type activity to those with low bone mass, this research is significant, said Vanessa Yingling, PhD, from the Department of Kinesiology at California State University, East Bay.
“Once women hit 60, they’re somehow regarded as frail, but that becomes a self-fulfilling prophecy when we take this kinder, gentler approach to exercise,” Yingling said in an interview. “Building bone density in older adults is important, but maintaining current bone density is just as crucial. Without high-impact activity, we are likely to see decelerating density at a faster rate.”
The other key to the recent research is the functional testing, Yingling added. In addition to bone density measures, high-intensity activity can improve mobility and muscle strength, as the study noted.
This type of activity can be done in shorter bursts, making these workouts more efficient, she explained. For example, a Tabata high-intensity interval training session usually takes about 10 minutes, warm-up and cool-down included.
“A HiRIT workout even once or twice a week would likely improve function, strength, and bone density maintenance,” Beck said. “The result of that would be better fall prevention and potentially less medication usage for BMD issues.”
Both men and women can benefit from a HiRIT workout, Beck and Yingling said. Initially, supervision by a knowledgeable trainer or physical therapist is ideal, they added.

Older adults, particularly postmenopausal women, are often advised to pursue low-impact, low-intensity exercise as a way to preserve joint health, but that approach might actually contribute to a decline in bone mineral density, researchers report.
Concerns about falls and fracture risk have led many clinicians to advise against higher-impact activities, like jumping, but that is exactly the type of activity that improves bone density and physical function, said Belinda Beck, PhD, professor at the Griffith University School of Allied Health Sciences in Southport, Australia.
“There has always been a quandary in terms of pursuing research on this,” she said in an interview. “We know from animal studies that bone only responds to high-intensity activity, but we worry about advising that for people with low bone mass, so instead we give them medications.”
“But not everyone likes to go on meds, they’re not 100% effective, and they’re not free of side effects,” said Beck, who is also the owner and director of The Bone Clinic in Brisbane, Australia.
In 2014, to assess whether high-intensity resistance and impact training (HiRIT) was a safe and effective way to improve bone mass, Beck and her colleagues conducted the LIFTMOR study of 101 postmenopausal women. The researchers showed that bone mineral density in the lumbar spine and femoral neck regions and functional performance measures were significantly better in the 49 participants randomized to HiRIT for 8 months than in the 52 randomized to low-intensity training.
Three years after the completion of LIFTMOR, the researchers looked at bone mineral density in 23 women from the HiRIT group in their retrospective observational study, the results of which were presented at the virtual American College of Sports Medicine 2020 Annual Meeting.

Pregnant women at greater risk for severe COVID-19, CDC says
Pregnant women may be at increased risk for severe COVID-19 illness, according to a new report published online June 26 in Morbidity and Mortality Weekly Report.
Among reproductive-aged women (15-44 years) infected with SARS-CoV-2, Pregnant women were 5.4 times more likely to be hospitalized, 1.5 times more likely to be admitted to the ICU, and 1.7 times more likely to need mechanical ventilation, after adjustment for age, underlying conditions, and race/ethnicity.
Furthermore, Hispanic and non-Hispanic black pregnant women appear to be disproportionately impacted by the infection.
Sascha Ellington, PhD, of the Centers for Disease Control and Prevention’s COVID-19 Response Pregnancy and Infant Linked Outcomes Team, and colleagues said that preventing COVID-19 infection in pregnant women should be a priority and any potential barriers to compliance with preventive measures need to be removed.
“During pregnancy, women experience immunologic and physiologic changes that could increase their risk for more severe illness from respiratory infections,” they wrote.
As of June 7, a total of 8,207 cases of COVID-19 in pregnant women were reported to the CDC, approximately 9% of COVID-19 cases among reproductive-aged women with known pregnancy status. The authors compared outcomes in these pregnant patients with those in 83,205 nonpregnant women with COVID-19. There was a substantially greater proportion of hospital admissions among pregnant patients (2,587; 31.5%) compared with nonpregnant patients (4,840; 5.8%) with COVID-19.
The authors cautioned that there were no data to differentiate between hospitalizations for COVID-19–related problems as opposed to those arising from pregnancy, including delivery.
For other severity measures, ICU admissions were reported for 1.5% of pregnant women compared with 0.9% for their nonpregnant counterparts, whereas mechanical ventilation was required for 0.5% compared with 0.3%, respectively. Mortality was identical, affecting 0.2% in both groups, with 16 deaths in pregnant patients with COVID-19 and 208 in nonpregnant patients.
Age had an impact as well, with hospitalization more frequent among those aged 35-44 years than among those aged 15-24, regardless of pregnancy status. When stratified by race/ethnicity, ICU admission was most frequently reported among pregnant women who were of non-Hispanic Asian lineage: 3.5% compared with 1.5% in all pregnant women.
Among pregnant women with laboratory-confirmed SARS-CoV-2 infection reporting race/ethnicity, 46% were Hispanic, 22% were black, and 23% were white, whereas among women who gave birth in 2019, 24% were Hispanic, 15% were black, and 51% were white. “Although data on race/ethnicity were missing for 20% of pregnant women in this study, these findings suggest that pregnant women who are Hispanic and black might be disproportionately affected by SARS-CoV-2 infection during pregnancy,” the authors wrote.
They noted that in a recent meta-analysis of influenza, pregnancy was similarly associated with a sevenfold risk for hospitalization, but a lower risk for ICU admission and no increased risk for death. A recent study suggested that COVID-19 severity during pregnancy may be lower than in other respiratory infections such as H1N1.
ACOG responds
In a response to the CDC findings, the American College of Obstetricians and Gynecologists (ACOG) advises calm, noting that the risk of needing the severity-associated interventions in the CDC report remains low and pregnant COVID-19 patients do not appear to have a greater risk for mortality.
Nevertheless, ACOG is reviewing all its COVID-19–related clinical and patient materials and “will make any necessary revisions to recommendations.”
In the meantime, the college advises clinicians to alert patients to the potential increased risk for severe COVID-19 illness during pregnancy. They should also stress to pregnant women and their families the need for precautions to prevent infection, paying particular attention to measures to protect those with greater occupational exposure to the virus.
ACOG also criticized the exclusion of pregnant and lactating women from clinical trials of potential coronavirus vaccines, noting that the new CDC findings underscore the importance of prioritizing pregnant patients to receive coronavirus vaccination when it becomes available.
“ACOG again urges the federal government to use its resources to ensure the safe inclusion of pregnant and lactating patients, including patients of color, in trials for vaccines and therapeutics to ensure that all populations are included in the search for ways to prevent and treat COVID-19,” the statement reads.
The CDC authors said that their report also highlights the need for more complete data to fully understand the risk for severe illness in pregnant women. To address these gaps, the CDC is collaborating with health departments in COVID-19 pregnancy surveillance for the reporting of outcomes in pregnant women with laboratory-confirmed SARS-CoV-2 infection.

Early hypertensive disorders in pregnancy linked to obesity
Rising classes of obesity are linked with progressively increased risk of early-onset hypertensive disorders in pregnant women, as has been established for late-onset hypertensive disorders, according to a U.S.-based retrospective cohort study.
Between 4% and 8% of pregnancies are impacted by hypertensive disorders, and preeclampsia is associated with a doubling of adverse neonatal events and causes 16% of maternal deaths in developed countries, previous studies have found. This study showed a clear risk of early-onset hypertensive disorders (less than 34 weeks’ gestation), which may be more deadly than late-onset disease: Compared with later-developing disorders, early hypertensive disorders are linked to a 400% increased risk of perinatal death and a 100%-300% increased risk of severe cardiovascular, renal, or hepatic maternal morbidity, according to previous studies.
The new research, led by Matthew Bicocca, MD, of the University of Texas Health Science Center, Houston, was published in Obstetrics & Gynecology. The researchers analyzed data from U.S. Vital Statistics, including over 14 million singleton births. The sample excluded women with chronic hypertension and a body mass index (BMI) below 18.5 kg/m2.
Previous studies demonstrated that obesity is a risk factor for late-onset hypertensive disorders, but studies of early-onset hypertensive disorders have yielded conflicting results. That could be because early-onset disorders are rare, representing just 5%-10% of hypertensive disorders during pregnancy, making it difficult to obtain a sufficient sample size to show a relationship.
“We know that obese pregnant women are at increased risk for adverse pregnancy outcomes, and this is of particular importance with the increasing prevalence of obesity in the United States. As this is a nationwide cohort with a large sample size, it allowed for evaluation of the rare outcome of early-onset hypertensive disorders of pregnancy,” said Iris Krishna, MD, MPH, an assistant professor of maternal-fetal medicine at Emory University, Atlanta, who was asked to comment on the study.
The researchers classified the women in the study as nonobese (BMI, 18.5-29.9 kg/m2; 46%), class I obese (BMI, 30.0-34.9; 29%), class II obese (BMI, 35.0-39.9; 15%), or class III obese (BMI, 40 or higher; 10%). About 6% of the participants developed hypertensive disorders during pregnancy (0.3% early onset), and the associated risk was greater with increasing class of obesity. Compared with nonobese women, class III obesity was associated with the highest adjusted risk ratio (2.18; 95% confidence interval, 2.12-2.24) for early-onset hypertensive disorders, followed by class II obesity (aRR, 1.57; 95% CI, 1.53-1.62) and class I (aRR, 1.13; 95% CI, 1.10-1.16). A similar pattern was observed with late-onset hypertensive disorders, with the highest risk associated with class III obese (aRR, 3.93; 95% CI, 3.91-3.96), followed by class II (aRR, 2.60; 95% CI, 2.58-2.62) and class I (aRR, 1.71; 95% CI, 1.70-1.73).
The mechanism underlying any potential link between obesity and risk of hypertensive orders of pregnancy isn’t completely understood, especially because the early-onset and late-onset hypertensive disorders have differing pathophysiology. “Early onset is the result from abnormal placentation [leading to] chronic placental insufficiency, and late onset likely [results from] placental insufficiency paired with oxidative stress from conditions such as obesity and insulin resistance,” Dr. Krishna said.
The new research reinforces the need for obese women to receive early prenatal care and counseling on nutrition and exercise “to mitigate weight gain during pregnancy in hopes of reducing their risk for adverse pregnancy outcomes, such as hypertensive disorders of pregnancy,” she concluded.
No source of funding was disclosed. The authors reported having no potential conflicts of interest.
