INTRODUCTION/BACKGROUND:The impact of maternal SARS-CoV-2 infection on fetal brain development during pregnancy remains unclear. Prior research has associated other antenatal infections with adverse neurodevelopmental outcomes in offspring. OBJECTIVE:To compare neurodevelopmental outcomes in infants born to mothers infected with SARS-CoV-2 during pregnancy (COVID+) to infants without congenital exposure (COVID-). METHODS:This study included 77 COVID+ infants and 157 COVID- infants assessed at 6 and/or 12 months. Outcomes were based on maternal self-report, observed infant behavior and brain fMRI. RESULTS:Overall, COVID+ and COVID- infant groups showed no significant differences across a range of neurobehavioral measures. However, analyses not adjusted for multiple comparisons revealed differences: fewer night awakenings at 6 (t(154) = 2.24, p < 0.03) and 12 months (t(107) = 1.94, p < 0.05), and reduced duration of orienting at 12 months (t(55.38) = 2.15, p < 0.04) in COVID+ infants. Neural differences were noted in posterior-anterior midline, insular-frontal, insular-posterior cingulate, and frontal-cingulate regions at an uncorrected threshold of p < 0.01. CONCLUSION/CONCLUSIONS:This study of multi-level infant development suggests that infants born to mothers infected with COVID during pregnancy are not experiencing harmful effects of that exposure. IMPACT/CONCLUSIONS:This study contributes comprehensive data on infant neurodevelopmental outcomes following prenatal SARS-CoV-2 exposure, evaluating a wide range of behavioral and neural measures to address gaps in previous research. Findings suggest that congenital exposure to SARS-CoV-2 does not result in significant neurodevelopmental impairments in infants, offering reassurance amidst concerns about potential long-term effects of maternal prenatal COVID-19 infection. Results indicate that any observed differences, such as fewer night awakenings and functional neural connectivity patterns, may reflect a more mature developmental profile in the exposed group. Continued longitudinal research is necessary to understand behaviorally relevant and lasting neurodevelopmental effects of prenatal SARS-CoV-2 exposure.

BACKGROUND:The maternal experience of intimate partner violence is associated with a range of emotional and behavioural problems in young children. OBJECTIVE:To prospectively examine the impact of maternal perinatal intimate partner violence experiences on children's risk trajectories of social-emotional development, including theoretically relevant social, economic, maternal mental health and trauma factors, as well as refugee status. PARTICIPANTS/METHODS:870 mother-child dyads in the WATCH mental health cohort study, half from refugee background. METHOD/METHODS:Multigroup trajectory modelling of annually collected longitudinal data at 5 timepoints, from when the children were 18-24 months to 60 months of age. RESULTS:The trajectory modelling revealed 4 distinct trajectories of child social-emotional development: (1) "none or low risk" trajectory (n = 710, 81.6 % of the sample); (2) "declining risk" trajectory (n = 66, 7.6 %); (3) "intermittent risk" trajectory (n = 64, 7.4 %); and (4) "high increasing risk" trajectory (n = 30; 3.4 %). Compared to the group 1 "none or low risk", maternal IPV exposure to physical abuse at baseline was associated with 2.45 times greater odds of children following the "intermittent risk" development trajectory, and 4.90 times greater odds of children following the "high increasing risk" trajectory. Children in trajectory 4 "high increasing risk" were more likely to be male, and mothers were more likely to be born in Australia, have no tertiary education, and experience social and economic difficulties. CONCLUSIONS:The study contributes significantly to understanding the deleterious impact of IPV on child development over time, including unique evidence that socially relevant and modifiable risk factors are more strongly associated with adverse child development than traditionally emphasised factors such as maternal mental health and child attachment factors.

IMPORTANCE/UNASSIGNED:General trauma is the leading cause of nonobstetric maternal morbidity and mortality, affecting approximately 8% of all pregnancies. Pregnant women with traumatic brain injury (TBI) face high morbidity and mortality rates, requiring complex management due to physiological changes, teratogenic risks of treatments, and the need for fetal monitoring. OBJECTIVES/UNASSIGNED:To assess the consequences of TBI during pregnancy on maternal and fetal outcomes and to evaluate management strategies to inform clinical decision-making. EVIDENCE REVIEW/UNASSIGNED:A systematic literature search was conducted on January 12, 2024, in PubMed, Web of Science, and PsycInfo to identify articles published in English, German, or Spanish between January 1, 1990, and December 31, 2023, that included at least 1 pregnant individual with TBI. Peer-reviewed, human-based studies with original data on maternal and fetal outcomes were included. Reviews, meta-analyses, and nonhuman studies were excluded. Two independent reviewers screened abstracts and full-text articles. Study characteristics, pregnancy outcomes (maternal and fetal), management methods, and authors' conclusions were extracted. Risk of bias was assessed by 2 reviewers, with interrater agreement measured using Cohen κ. Disagreements were resolved through discussion. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) reporting guideline was followed. FINDINGS/UNASSIGNED:This systematic review included 16 articles involving a total of 4112 individuals (mean maternal age, 26.9 years; range, 16-47 years) who experienced TBI during pregnancy (mean gestational age at injury, 24 weeks; range, 3-38 weeks). The articles comprised 10 case reports, 2 case series, and 4 cohort studies. Motor vehicle crashes were the most common cause of injury, reported in 12 articles. The average Glasgow Coma Scale score ranged from 3 to 15 across all individuals. Conservative management was reported in 7 case patients, whereas surgery was performed in 6 case patients. Maternal outcomes ranged from functional recovery to severe cognitive impairment, and fetal outcomes varied from stable to severe adverse outcomes, including stillbirth and death. Risk of bias assessment indicated moderate to good methodological validity overall, but most articles demonstrated poor quality of evidence. CONCLUSIONS AND RELEVANCE/UNASSIGNED:In this review, no definitive association between TBI during pregnancy and maternal or fetal outcomes was found owing to conflicting findings, poor to moderate study quality, and limited evidence. Although some articles suggested increased risks such as placental abruption and cesarean delivery, the findings remained inconclusive. The findings of this review underscore the need for high-quality research, standardized reporting, and rigorous methodology to improve data reliability. Future research should focus on developing consensus-driven, multidisciplinary management strategies to improve maternal and fetal outcomes.

INTRODUCTION/BACKGROUND:During the COVID-19 pandemic, birthing parents were identified as a high-risk group with greater vulnerability to the harms associated with SARS-CoV-2. This led to necessary changes in perinatal health policies but also to experiences of maternal isolation and loneliness, both in hospital settings, due to infection mitigation procedures, and once home, due to social distancing. METHODS:In this study, we qualitatively explored birthing and postpartum experiences in New York City during the early days of the pandemic when lockdowns were in effect and policies and practices were rapidly changing. Using thematic analysis, our focus was on experiences of isolation, navigating these experiences, and the potential impacts of isolation and loneliness on maternal health for 55 birthing people. RESULTS:Participants described numerous stressors related to isolation during the birthing process, including reconciling their hopes for their birth with the realities of the unknown and separation from partners, family, and friends in the hospital. During the postpartum period, loneliness manifested as having limited or no contact with family and friends, which led to feelings of a need for strengthened social support systems. The impact of these negative experiences shaped mental health. Overall, we found that solitary experiences during birthing and postpartum isolation were major sources of stress for participants in this study. DISCUSSION/CONCLUSIONS:To support impacted families and prepare for future crisis events, clinicians and researchers must prioritize the development of strong clinical and social support structures for perinatal people to ensure both maternal and child health.

The perinatal period represents a time of profound neurobiological, cognitive, and emotional change. While evidence points to the neuroplasticity of matrescence as adaptive in supporting the transition to motherhood, the perinatal period also entails subjective reports of cognitive difficulty known as "mommy brain" as well as a heightened vulnerability to mental health challenges. The role of cognition in the etiology of postpartum depression is a promising area of investigation into targets for maternal mental health intervention, considering evidence that important cognitive changes occur during the perinatal period, and given that cognitive alterations are key features of mood disorders. Here we review evidence for cognitive plasticity in matrescence, with a particular focus on executive function (EF) given its overlapping significance for adaptation to parenthood, central role in managing the mental load of motherhood, and implications in mood regulation and mood disorders. We also review evidence for EF changes in perinatal depression and major depressive disorder more broadly. Despite the strong association between EF impairments and major depressive disorder, research on EF changes in perinatal depression remains limited. Understanding normative EF changes during this period is essential for better understanding the relationship between EF, perinatal depression, and the mental load of motherhood. Consideration for these cognitive, neurobiological, and psychosocial factors of matrescence is critical for addressing maternal mental health and developing interventions that support parental well-being.

BACKGROUND:Long-term deterioration in the mental health of healthcare workers (HCWs) has been reported during and after the COVID-19 pandemic. Determining the impact of COVID-19 incidence and mortality rates on the mental health of HCWs is essential to prepare for potential new pandemics. This study aimed to investigate the association of COVID-19 incidence and mortality rates with depressive symptoms over 2 years among HCWs in 20 countries during and after the COVID-19 pandemic. METHODS:This was a multi-country serial cross-sectional study using data from the first and second survey waves of the COVID-19 HEalth caRe wOrkErS (HEROES) global study. The HEROES study prospectively collected data from HCWs at various health facilities. The target population included HCWs with both clinical and non-clinical roles. In most countries, healthcare centers were recruited based on convenience sampling. As an independent variable, daily COVID-19 incidence and mortality rates were calculated using confirmed cases and deaths reported by Johns Hopkins University. These rates represent the average for the 7 days preceding the participants' response date. The primary outcome was depressive symptoms, assessed by the Patient Health Questionnaire-9. A multilevel linear mixed model (LMM) was conducted to investigate the association of depressive symptoms with the average incidence and mortality rates. RESULTS:A total of 32,223 responses from the participants who responded to all measures used in this study on either the first or second survey, and on both the first and second surveys in 20 countries were included in the analysis. The mean age was 40.1 (SD = 11.1), and 23,619 responses (73.3%) were from females. The 9323 responses (28.9%) were nurses and 9119 (28.3%) were physicians. LMM showed that the incidence rate was significantly and positively associated with depressive symptoms (coefficient = 0.008, standard error 0.003, p = 0.003). The mortality rate was significantly and positively associated with depressive symptoms (coefficient = 0.049, se = 0.020, p = 0.017). CONCLUSIONS:This is the first study to show an association between COVID-19 incidence and mortality rates with depressive symptoms among HCWs during the first 2 years of the outbreak in multiple countries. This study's findings indicate that additional mental health support for HCWs was needed when the COVID-19 incidence and mortality rates increase during and after the early phase of the pandemic, and these findings may apply to future pandemics.

OBJECTIVE:Being a mother of a young child may be protective against alcohol misuse for some, but not all, women. This is the first study to identify the mental health and psychosocial correlates of alcohol misuse among postpartum mothers. METHOD/METHODS:= 319) were recruited via social media to complete a cross-sectional online survey. Two hierarchical logistic regressions examined unique factors associated with heavy episodic drinking and hazardous alcohol use, including sociodemographic, poor mental health, and psychosocial factors. RESULTS:On average, mothers drank alcohol at low levels (4 drinking days, nine standard drinks in the past month). One in 10 (11.6%) reported heavy episodic drinking during this time, and 1 in 12 (8.5%) were drinking at hazardous or greater levels. In the final models, older age and more severe postpartum anxiety were associated with a higher likelihood of hazardous drinking (odds ratio [OR] = 1.37, 1.09, respectively), whereas breastfeeding was associated with lower odds of heavy episodic drinking (OR = 0.29). Greater perceived social support was associated with lower odds of heavy episodic (OR = 0.56) and hazardous (OR = 0.39) drinking, whereas higher coping-with-anxiety and social-drinking motives were associated with greater odds of both forms of alcohol misuse (ORs = 3.51-10.40). Conformity drinking motives (e.g., drinking to avoid social rejection) were negatively associated with heavy episodic drinking (OR = 0.24). CONCLUSIONS:Maternal anxiety, coping-with-anxiety and social-drinking motives, and reduced social support are important factors associated with postpartum alcohol misuse. These modifiable factors are potential targets for screening and intervention for mothers who may need additional support and preventative care.

Healthcare workers (HCWs) were at increased risk for mental health problems during the COVID-19 pandemic, with prior data suggesting women may be particularly vulnerable. Our global mental health study aimed to examine factors associated with gender differences in psychological distress and depressive symptoms among HCWs during COVID-19. Across 22 countries in South America, Europe, Asia and Africa, 32,410 HCWs participated in the COVID-19 HEalth caRe wOrkErS (HEROES) study between March 2020 and February 2021. They completed the General Health Questionnaire-12, the Patient Health Questionnaire-9 and questions about pandemic-relevant exposures. Consistently across countries, women reported elevated mental health problems compared to men. Women also reported increased COVID-19-relevant stressors, including insufficient personal protective equipment and less support from colleagues, while men reported increased contact with COVID-19 patients. At the country level, HCWs in countries with higher gender inequality reported less mental health problems. Higher COVID-19 mortality rates were associated with increased psychological distress merely among women. Our findings suggest that among HCWs, women may have been disproportionately exposed to COVID-19-relevant stressors at the individual and country level. This highlights the importance of considering gender in emergency response efforts to safeguard women's well-being and ensure healthcare system preparedness during future public health crises.
