Breastfeeding and neurodevelopment in infants with prenatal alcohol exposure.

BACKGROUND: Few studies have evaluated the differential benefits of breastfeeding on infant neurodevelopment at varying levels of prenatal alcohol exposure (PAE). This study examined whether the association between breastfeeding and neurodevelopment is modified by prenatal drinking pattern. METHODS: The study included 385 infants from Ukraine born to women prospectively enrolled in a cohort study during pregnancy. Neurodevelopment was assessed at six and 12 months using the Bayley Scales of Infant Development II (BSID-II) Mental Developmental Index (MDI) and Psychomotor Developmental Index (PDI). Linear regression modeling with interaction terms and stratification by PAE group was used to determine the relationship between breastfeeding, PAE, and neurodevelopment. RESULTS: A significant interaction between PAE and breastfeeding was observed for the MDI and PDI at six and 12 months. Infants with high PAE who were breastfed at least four months had BSID-II scores 14 or more points higher compared to those never breastfed. Counterintuitively, those with moderate PAE had poorer performance on the BSID-II at 12 months when breastfed longer. CONCLUSION: There was a significant joint effect of PAE and breastfeeding on infant neurodevelopment at six and 12 months. Breastfeeding may provide distinct benefits to infants exposed to high levels of PAE. IMPACT: We found a positive effect of breastfeeding on infant neurodevelopment among infants with prenatal alcohol exposure (PAE), particularly those exposed to higher levels during gestation. This study is one of the first to evaluate whether breastfeeding mitigates harm caused by PAE. Breastfeeding may provide distinct benefits to infants with higher levels of PAE.

Blood culture procedures and practices in the neonatal intensive care unit: A survey of a large multicenter collaborative in California.

OBJECTIVE: To describe variation in blood culture practices in the neonatal intensive care unit (NICU). DESIGN: Survey of neonatal practitioners involved with blood culturing and NICU-level policy development. PARTICIPANTS: We included 28 NICUs in a large antimicrobial stewardship quality improvement program through the California Perinatal Quality Care Collaborative. METHODS: Web-based survey of bedside blood culture practices and NICU- and laboratory-level practices. We evaluated adherence to recommended practices. RESULTS: Most NICUs did not have a procedural competency (54%), did not document the sample volume (75%), did not receive a culture contamination report (57%), and/or did not require reporting to the provider if <1 mL blood was obtained (64%). The skin asepsis procedure varied across NICUs. Only 71% had a written procedure, but ≥86% changed the needle and disinfected the bottle top prior to inoculation. More than one-fifth of NICUs draw a culture from an intravascular device only (if present). Of 13 modifiable practices related to culture and contamination, NICUs with nurse practitioners more frequently adopted >50% of practices, compared to units without (92% vs 50% of units; P < .02). CONCLUSIONS: In the NICU setting, recommended practices for blood culturing were not routinely performed.

Drinking water and the implications for gender equity and empowerment: A systematic review of qualitative and quantitative evidence.

BACKGROUND: Safe drinking water is a fundamental human right, yet more than 785 million people do not have access to it. The burden of water management disproportionately falls on women and young girls, and they suffer the health, psychosocial, political, educational, and economic effects. While water conditions and disease outcomes have been widely studied, few studies have summarized the research on drinking water and implications for gender equity and empowerment (GEE). METHODS: A systematic review of primary literature published between 1980 and 2019 was conducted on drinking water exposures and management and the implications for GEE. Ten databases were utilized (EMBASE, PubMed, Web of Science, Cochrane, ProQuest, Campbell, the British Library for Development Studies, SSRN, 3ie International Initiative for Impact Evaluation, and clinicaltrials.gov). Drinking water studies with an all-female cohort or disaggregated findings according to gender were included. RESULTS: A total of 1280 studies were included. GEE outcomes were summarized in five areas: health, psychosocial stress, political power and decision-making, social-educational conditions, and economic and time-use conditions. Water quality exposures and implications for women's health dominated the literature reviewed. Women experienced higher rates of bladder cancer when exposed to arsenic, trihalomethanes, and chlorine in drinking water and higher rates of breast cancer due to arsenic, trichloroethylene, and disinfection byproducts in drinking water, compared to men. Women that were exposed to arsenic experienced higher incidence rates of anemia and adverse pregnancy outcomes compared to those that were not exposed. Water-related skin diseases were associated with increased levels of psychosocial stress and social ostracization among women. Women had fewer decision-making responsibilities, economic independence, and employment opportunities around water compared to men. CONCLUSION: This systematic review confirms the interconnected nature of gender and WaSH outcomes. With growing attention directed towards gender equity and empowerment within WaSH, this analysis provides key insights to inform future research and policy.
