Abstract Background Prenatal endocrine disrupting chemical (EDC) exposure has been associated with increased risk of preterm birth. Non-Hispanic Black women have higher incidence of preterm birth compared to other racial/ethnic groups and may be disproportionately exposed to EDCs through EDC-containing hair products. However, research on the use of EDC-associated hair products during pregnancy and risk of preterm birth is lacking. Therefore, the objective of this pilot study was to estimate associations of prenatal hair product use with gestational age at delivery in a Boston, Massachusetts area pregnancy cohort. Methods The study population consisted of a subset of participants enrolled in the Environmental Reproductive and Glucose Outcomes (ERGO) Study between 2018 and 2020. We collected self-reported data on demographics and hair product use using a previously validated questionnaire at four prenatal visits (median: 12, 19, 26, 36 weeks’ gestation) and abstracted gestational age at delivery from medical records. We compared gestational age and hair product use by race/ethnicity and used linear regression to estimate covariate-adjusted associations of product use and frequency of use at each study visit with gestational age at delivery. Primary models were adjusted for maternal age at enrollment and delivery method. Results Of the 154 study participants, 7% delivered preterm. Non-Hispanic Black participants had lower mean gestational age at delivery compared to non-Hispanic White participants (38.2 vs. 39.2 weeks) and were more likely to report ever and more frequent use of hair products. In regression models, participants reporting daily use of hair oils at visit 4 had lower mean gestational age at delivery compared to non-users (β: -8.3 days; 95% confidence interval: -14.9, -1.6). We did not find evidence of associations at earlier visits or with other products. Conclusions Frequent use of hair oils during late pregnancy may be associated with shorter gestational duration. As hair oils are more commonly used by non-Hispanic Black women and represent potentially modifiable EDC exposure sources, this may have important implications for the known racial disparity in preterm birth.

Abstract Background In Bangladesh, abortion is illegal except to save a woman’s life, though menstrual regulation (MR) is permitted. MR involves the use of manual uterine aspiration or Misoprostol (with or without Mifepristone) to induce menstruation up to 10–12 weeks from the last menstrual period. Despite the availability of safe and legal MR services, abortions still occur in informal setttings and are associated with high complication rates, causing women to then seek post abortion care (PAC). The objective of this study is to contextualize MR in Bangladesh and understand systemic barriers to seeking care in formal settings and faciltators to seeking care in informal settings via the perspective of MR providers in an effort to inform interventions to improve MR safety. Methods Qualitative individual semi-structured interviews were conducted with 25 trained MR providers (doctors and nurses) from urban tertiary care facilities in six different cities in Bangladesh from April to July, 2018. Interviews explored providers’ knowledge of MR and abortion in Bangladesh, knowledge/experience with informal MR providers, knowledge/experience with patients attempting self-managed abortion, personal attitudes and moral perspectives of MR/abortion in general, and barriers to formal MR. Team based coding and a directed content analysis approach was performed by three researchers. Results There were three predominant yet overlapping themes: (i) logistics of obtaining MR/PAC/abortion, (ii) provider attitudes, and (iii) overcoming barriers to safe MR. With regards to logistics, lack of consensus among providers revealed challenges with defining MR/abortion gestational age cutoffs. Increasing PAC services may be due to patients purchasing Mifepristone/Misoprostol from pharmacists who do not provide adequate instruction about use, but are logistically easier to access. Patients may be directed to untrained providers by brokers, who intercept patients entering the hospitals/clinics and receive a commission from informal clinics for bringing patients. Provider attitudes and biases about MR can impact who receives care, creating barriers to formal MR for certain patients. Attitudes to MR in informal settings was overwhelmingly negative, which may contribute to delays in care-seeking and complications which endanger patients. Perceived barriers to accessing formal MR include distance, family influence, brokers, and lack of knowledge. Conclusions Lack of standardization among providers of MR gestational age cutoffs may affect patient care and MR access, causing some patients to be inappropriately turned away. Providers in urban tertiary care facilities in Bangladesh see primarily the complicated MR/PAC cases, which may impact their negative attitude, and the safety of out-of-clinic/self-managed abortion is unknown. MR safety may be improved by eliminating brokers. A harm reduction approach to improve counseling about MR/abortion care in pharmacies may improve safety and access. Policy makers should consider increasing training of frontline health workers, such as Family Welfare Visitors to provide evidence-based information about Mifepristone/Misoprostol.

Context: An excess of the soluble receptor, fms-like tyrosine kinase 1 (sFlt-1) may contribute to maternal vascular dysfunction in women with preeclampsia by binding and thereby reducing concentrations of free vascular endothelial growth factor and placental growth factor (PlGF) in the circulation. The putative stimulus for increased sFlt-1 during preeclampsia, placental hypoxia due to poor perfusion, is common to both preeclampsia and idiopathic intrauterine growth restriction. However, the latter condition occurs without maternal vascular disease. Objective: We asked whether, as with preeclampsia, sFlt-1 is increased and free PlGF is decreased in villous placenta and maternal serum of normotensive women with small-for-gestational-age (SGA) neonates. Study Design: This was a case-control study using banked samples. Groups of women with SGA neonates (birth weight centile < 10th) and women with preeclampsia were matched to separate sets of normal pregnancy controls based on gestational age at blood sampling (serum) or gestational age at delivery (placenta). Results: sFlt-1 levels were higher in preeclamptics than controls (serum, P < 0.0001; placental protein, P = 0.03; placental mRNA, P = 0.007) but not increased in SGA pregnancies. PlGF was lower in both preeclampsia (serum, P < 0.0001; placental protein, P = 0.05) and SGA (serum, P = 0.0008; placental protein, P = 0.03) compared with their controls. PlGF in preeclampsia and SGA groups did not differ. Conclusions: These data are consistent with a role for sFlt-1 in the maternal manifestations of preeclampsia. In contrast to preeclampsia, sFlt-1 does not appear to contribute substantially to decreased circulating free PlGF in SGA pregnancies in the absence of a maternal syndrome.

<p><strong>Objective:</strong> The aim of this study was to investigate the effect of some maternal and neonatal clinical parameters on the neonatal intensive care unit admission rates of neonates born to mothers who had preeclampsia. </p><p><strong>Study Design:</strong> Study included 402 singleton pregnant women with preeclampsia who admitted to Maternal-Fetal Medicine Unit of Zeynep Kamil Children and Women’s Health Training and Research Hospital. Pregnancies with uterine rupture, chorioamnionitis and congenital malformations were excluded. Some maternal and neonatal clinical characteristics were assessed to predict neonatal intensive care unit admission.</p><p><strong>Results:</strong> Among 402 neonates, 140 (35%) of them had an indication for neonatal intensive care unit admission, among 140 neonates, 136 (97%) of them were preterm neonates. Comparison of groups with and without neonatal intensive care unit admission indicated significant differences between groups in terms of gestational age, Apgar scores at 1st and 5th minutes, birth weight, some maternal laboratory parameters (Hemoglobin, hematocrit, alanine aminotransferase, aspartate aminotransferase, albumin). In multivariate analysis, among all study population, gestational age at delivery, birth weight and Apgar scores were found to be significantly associated with neonatal intensive care unit admission. On the other hand, in subgroup of term neonates, none of the variables was shown to be associated with neonatal intensive care unit admission.</p><p><strong>Conclusion:</strong> Gestational age at delivery and the birth weight are the main risk factors for neonatal intensive care unit admission of neonates born to mothers who had preeclampsia.</p>
