"We were left to our own devices": Midwives' experiences of providing maternity care to Ukrainian women in Poland after the outbreak of the full-scale war in Ukraine
Women and Birth
This qualitative study aimed to explore the challenges and strategies of midwives offering maternity care to Ukrainian migrants. The findings revealed barriers at individual and interpersonal levels, such as fear for life and well-being due to the war, depleting resources, post-pandemic fatigue, language barriers, and lack of knowledge in caring for war-affected women. At the management and organizational level, midwives faced a lack of organizational support and interpreting services. The study concluded that systemic solutions, jointly prepared by state and local authorities and considering midwives' insights, are essential to provide high-quality care to the migrant population.

Advancing Clinical Research with Pregnant and Lactating Populations
National Academies
Congress called on the National Academies to convene a committee to examine the real and perceived risks of liability arising from research conducted with pregnant and lactating women. The resulting report, Clinical Research with Pregnant and Lactating Populations: Overcoming Real and Perceived Liability Risks, explores and finds limited evidence of legal liability for inclusion of pregnant and lactating women in clinical research, contradicting perceptions of heightened liability. The committee also makes recommendations that could lead to a more robust evidence base about the safety and efficacy of medications for pregnant and lactating women that would facilitate more informed decision making regarding care while mitigating liability.

Association between maternity care practitioner type and postpartum depression screening
Birth Issues in Perinatal Care
The study investigated postpartum depression (PPD) screening among California residents who gave birth in 2016, using data from the Listening to Mothers in California 2018 dataset. The primary focus was on the type of maternity care professional provided during pregnancy and its association with PPD screening. Self-reported depression or anxiety during pregnancy and attendance at postpartum office visits were also examined. Results showed that participants cared for by midwives had 2.6 times higher odds of being screened for PPD compared to those cared for by obstetricians, after adjusting for covariates. No significant differences were found in PPD screening rates when comparing care from other practitioner types to obstetricians. Additionally, reporting depression or anxiety during pregnancy was associated with lower odds of attending a postpartum office visit. The study concludes that receiving care from a midwife during pregnancy increases the likelihood of PPD screening. Furthermore, it highlights that even with universal screening, there remains a vulnerable population at high risk for PPD who are less likely to attend postpartum care visits.

Breastfeeding duration and associations with prevention of accelerated growth among infants from low-income, racially, and ethnically diverse backgrounds
Public Health Nutrition
In this prospective cohort study involving 256 low-income, racially diverse mother-infant pairs in the Southeastern US, breastfeeding patterns and their impact on infant growth were investigated. Most participants were African American or Latina, with 81% enrolled in a nutritional program for women and infants. The study found that infants breastfed beyond 6 months had slower growth rates compared to those breastfed for shorter periods, indicating a link between extended breastfeeding and reduced rapid weight gain. Infants breastfed for 2 months or less were more likely to experience rapid weight gain than those breastfed for 6 months or more, suggesting that prolonged breastfeeding may contribute to more equitable health outcomes among diverse populations, potentially aiding in preventing accelerated growth and childhood obesity.

As a traditionally underserved population that faces numerous health disparities, youth who identify as transgender and gender diverse (TGD) and their families are increasingly presenting to pediatric providers for education, care, and referrals. The need for more formal training, standardized treatment, and research on safety and medical outcomes often leaves providers feeling ill equipped to support and care for patients that identify as TGD and families. In this policy statement, we review relevant concepts and challenges and provide suggestions for pediatric providers that are focused on promoting the health and positive development of youth that identify as TGD while eliminating discrimination and stigma

Epidural analgesia during labour and severe maternal morbidity: population based study
The BMJ
This population-based study in Scotland involving 567,216 women in labor aimed to assess the impact of labor epidural on severe maternal morbidity (SMM) and explore its effects in women with medical indications or preterm labor. Of these women, 22.0% received epidural analgesia. SMM occurred in 4.3 per 1000 births. Epidural analgesia was associated with a 35% reduction in SMM, with even greater risk reductions observed in women with medical indications or delivering preterm. Access to epidural analgesia during labor, especially for high-risk groups, could significantly improve maternal health outcomes.

Examination of maternal near-miss experiences in the hospital setting among Black women in the United States
Women's Health vol. 18
The high rate of maternal mortality among Black women in the United States continues to gain attention; yet research has not yet fully illuminated the precursors to these events, most impactful among them being “maternal near misses.” Researchers have focused on reviewing patient medical records after sentinel maternal events to help determine major contributors to them; however, qualitative studies with near-miss survivors, especially among Black women, may be a more useful approach.

Examining the impact of a change in maternity leave policy in Canada on maternal mental health care visits to the physician
Archives of Women's Mental Health
This study aimed to investigate the impact of an extended maternity leave policy on maternal use of mental health services and prescription drugs in a universal public healthcare system. Analyzing administrative medical records of 18,000 randomly selected women who gave birth three months before and after the policy extension, the research revealed that mothers with the extended maternity leave (50 weeks) had 0.12 fewer medical visits and incurred Can$5 less in mental health service costs compared to those with shorter leave (26 weeks). These differences were observed specifically during the extended maternity leave period. The findings suggest that the additional time away from work provided by an extended maternity leave policy may contribute to a better balance in new family dynamics, potentially resulting in decreased demand on the healthcare system.

Exploring the intersection between country context and priority setting to prevent maternal mortality: A multi-methods study comparing expected vs observed priorities in five countries to validate the obstetric transition model
Journal of Global Health
In this mixed-methods study design, researchers aimed to validate the obstetric transition model using data from six diverse low- and middle-income countries representing self-identified priorities for improving maternal health and measurement compiled in a multi-stakeholder process. Using multiple data sources from Bangladesh, Cote d’Ivoire, India, Mexico, Nigeria, and Pakistan, the authors conducted a four-phased analysis: examining the country’s contextual profile, mapping the key themes and indicators to the model, exploring stakeholder prioritization, and examining reasons for divergence from the model. They found the obstetric transition model to be a useful guide to aid decision-makers in prioritizing attention towards addressing maternal mortality.

Facilitators and Barriers to Medicaid Doula Benefit Implementation in California: Perspectives From Managed Care Plans and Risk-Bearing Organizations
Women's Health Issues
This study explores the implementation of Medicaid doula benefits in California, which began in 2023 to address maternal health inequities. By conducting 14 interviews with staff from managed care plans (MCPs) and risk-bearing organizations (RBOs), we identified 10 facilitators and 16 barriers to the effective rollout of these benefits. Key findings highlight the need for better familiarity with doula care, relationship building with doulas, and collaboration among plans. These insights can guide improvements in California and assist other states in planning and designing their Medicaid doula benefits. This publication is detailed, so to aid in understanding, Berkeley Public Health created a brief summarizing the study.

GDF15 linked to maternal risk of nausea and vomiting during pregnancy
Nature
Nausea and vomiting (NVP) affect approximately 70% of pregnancies and can be debilitating, sometimes resulting in risks to the health of both mother and baby. In this study, researchers share their findings that fetal production of GDF15, a hormone acting on the brainstem, and maternal sensitivity to it, both contribute substantially to the risk of Hyperemesis Gravidarum (HG), the most severe form of NVP. This landmark study provides concrete evidence of a cause of nausea and vomiting in pregnancy as well as a potential mechanism for treating and preventing HG.

Having Enough Milk to Sustain a Lactation Journey: A Call to Action
Nursing for Women's Health
The rates of human milk feeding are suboptimal worldwide. Recommendations for healthy, term mother–infant dyads include early breastfeeding initiation, frequent skin-to-skin contact, and frequent breastfeeding. Given that the first 2 to 3 days postpartum are critical to achieving timely secretory activation and establishing an adequate volume of milk, a proactive approach to care can include building awareness of risk factors and development of protocols for the effective early initiation of lactation.

Infant Feeding for Persons Living With and at Risk for HIV in the United States: Clinical Report
American Academy of Pediatrics
This clinical report discusses the role of pediatricians and pediatric health care professionals in guiding infant feeding practices for infants born to people living with and at risk for HIV infection, emphasizing the need for awareness of the HIV transmission risk from breastfeeding and the recommendations for feeding infants with perinatal HIV exposure in the United States. The risk of HIV transmission via breastfeeding from a parent on antiretroviral treatment (ART) and virally suppressed is estimated to be less than 1%. The American Academy of Pediatrics recommends avoiding breastfeeding as the only option with 0% transmission risk. However, some parents with HIV may wish to breastfeed, and pediatricians should provide a family-centered, nonjudgmental, harm reduction approach to support those on ART with sustained viral suppression. For those not on ART or without viral suppression, breastfeeding is strongly discouraged. This article provides insight for clinicians navigating these discussions and decisions with their patients.

Interventions to Improve Safer Sleep Practices in Families With Children Considered to Be at Increased Risk for Sudden Unexpected Death in Infancy: A Systematic Review
frontiers in Pediatrics
Advice to families to follow infant care practices known to reduce the risks of Sudden Unexpected Death in Infancy (SUDI) has led to a reduction in deaths across the world. This reduction has slowed in the last decade with most deaths now occurring in families experiencing social and economic deprivation. A systematic review of the literature covered three areas: interventions to improve engagement with support services, parental decision-making for the infant sleep environment, and interventions to improve safer sleep practices in families with infants considered to be at risk of SUDI.

Issue Brief: Black Maternal Mental Health
2020 Mom
This brief discusses the prevalence and repercussions of maternal mental health disorders, specifically focusing on maternal depression and anxiety during the perinatal or postpartum period. Approximately 20% of women experience these disorders, leading to an estimated economic cost of $14.2 billion over five years for untreated cases. The societal impact extends to early childhood development, pediatric mental health, and overall family well-being. Women of color, particularly Black women, face heightened vulnerability due to increased rates of trauma exposure, reaching 87% during the perinatal period. Coupled with a higher likelihood of perilous birth complications, Black women are 3-4 times more susceptible to maternal mental health disorders, including birth trauma and post-traumatic stress disorder. Additional risk factors encompass exposure to adverse health determinants, chronic stress, and gendered racism throughout their lifespan.
