ABSTRACT With the recent surge in cannabis legalization across North America, there is legitimate concern that rates of use during pregnancy will dramatically increase coming years. However, long-term impacts prenatal exposure (PCE) on brain and behavior remain poorly understood. Using a model passive vapor exposure, we have previously shown PCE impairs behavioral flexibility an attentional set-shifting task adult offspring, which orchestrated part by excitatory inputs from medial prefrontal cortex (mPFC) to nucleus accumbens (NAc). Given fundamental role these corticostriatal coordinating flexible reward-seeking strategies, used combination retrograde tracing ex vivo electrophysiology test hypothesis maternal alters synaptic intrinsic membrane properties efferent neurons exposed male female rat offspring. Specifically, pregnant dams were trained self-administer vaporized (69.7% THC; 150 mg/ml) twice daily throughout mating gestation offspring subsequently injected with fluorescent retrobeads into NAc core prior conducting whole-cell recordings spontaneous inhibitory post-synaptic currents (EPSC IPSC, respectively) retrolabeled mPFC adulthood.

OBJECTIVE: To understand pregnant patients' reasons for prenatal cannabis use and perceptions of safety, desired undesirable health care experiences, information about secondarily to racial differences in these preferences. METHODS: We conducted a qualitative study including 18 semi-structured, race-concordant virtual focus groups with individuals who self-reported at entry large integrated system Northern California from November 2021 December 2021. The included semi-structured questions that were recorded, transcribed, coded by the research team. Thematic analysis was used analyze data. RESULTS: Overall, 53 participants included; 30 self-identified, as White 23 self-identified Black. Participants averaged 30.3 years age (SD 5.2 years) on average 20.9 weeks gestation enrollment; 69.8% reported daily use, 24.5% weekly 5.7% monthly or less entrance care. Although some quit early pregnancy because concerns potential risks, many perceived lack scientific evidence believed safe. Many preferred over-the-counter prescription medications treating mood, morning sickness, pain, sleep. valued open interactions obstetricians acknowledged their motivations they risks through conversations educational materials. Black participants' perspectives generally similar, but few uniquely described bias related use. CONCLUSION: Pregnant patients manage mood medical symptoms, safer than medications. Obstetrician-initiated, patient-centered around advice discontinue during pregnancy, exploration willingness switch medically recommended interventions pregnancy-related symptoms may benefit patients.

Introduction: Young childbearing sexual minority (SM) people are more likely to use cannabis and have an unintended pregnancy than their heterosexual peers; however, little is known about perceptions experiences of peripartum use. This qualitative study explores the relationships young pregnant parenting SM with cannabis, as well feelings opinions prenatal Method: Participants who identified from baseline surveys YoungMoms were recruited for semi-structured interviews (n = 13). Interviews focused on before during pregnancy. Data analyzed using thematic analysis. Results: analysis revealed 3 key themes. described contextual adaptivity use, discussing how changed based social context, mental health, stress but was not directly related sexuality. Pregnancy a potential turning point participants trying reduce or abstain pregnancy, although some struggled do so continued address symptoms. Facilitating factors reduction described, including focusing financial toll, environment changes, access health-related guidance, replacement hobbies. Conclusions: provides novel information public health concern among population that often overlooked in substance research. Similar peers, may serve opportune time intervention consideration unique contribute needed.

Abstract Mental health disorders affect over 1 billion people worldwide, profoundly impacting individuals, families, and the global economy. Risk for psychopathology begins early in life, with perinatal period representing a critical window of vulnerability. The Brain Begins Before Birth (B4) Study at Massachusetts General Hospital (MGH) is prospective birth cohort designed to identify modifiable risk resilience factors influencing brain development child- adult-onset psychopathology. This study aims deeply phenotype prenatal exposures through maternal surveys administered multiple time points during after pregnancy; assess neurodevelopmental outcomes first two years life; triangulate exposure outcome data underlying biological mechanisms. B4 consists structured, remote covering psychosocial, environmental, health-related throughout pregnancy supplemented by medical record review. By integrating into dynamic learning model, advance field preventive psychiatry identifying actionable pathways intervention, testing strategies real-time, ultimately shaping policies that promote lifelong mental wellbeing from earliest stages development.

Abstract Background Neonatal mortality is a significant challenge that affects babies within the first 28 days of life. The issue particularly challenging for healthcare systems in developing countries, where interventions are required. Although there has been decline neonatal worldwide, comprehensive data on patterns and contributing factors rural regions Ethiopia lacking. Objective To determine trends using 2011-2019 DHS Methods Ethiopian demographic health survey (EDHS) program conducted cross-sectional community-based study 2011, 2016, 2019. included women who gave birth specified timeframe agreed to participate. Sampling was done through multistage cluster approach, STATA version 17 used analyze data. Predictor variables were validated multiple logistic regression analysis. Weighted estimates derive population-level statistics p-value less than 0.05 considered significant. Results analyzed from 22,755 participated EDHS surveys between 2011 rates decreased 7.5% 6.03%. Regional variations observed, with Gambela Tigrai having lowest rates, Dire Dawa Somali region higher rates. Factors like mother’s age, wealth index, order, neonate’s sex, presence twins, immediate breastfeeding, baby’s size associated mortality. Conclusion recommendation Despite advancements have made decrease mortality, remain challenges need be addressed. Therefore, regional bureaus should strengthen their strategies enhance antenatal care (ANC) visits promote delivery at facilities.
