Little is known about ecstasy/MDMA use among Asian American and Pacific Islander populations. Research is important because AAPIs face unique cultural factors that may influence use. We estimated the prevalence and correlates of lifetime ecstasy/MDMA use based on a representative sample of US AAPI adults aged ≥18 from the 2015-2020 National Survey on Drug Use and Health. An estimated 5.1% of AAPI adults used ecstasy in their lifetime. Compared to males, females had higher odds of use (aOR = 1.45, 95% CI: 1.08-1.98). Compared to those aged 18-25, those aged 26-34 were at increased odds for use (aOR = 1.99, 95% CI: 1.30-3.06), while those aged ≥50 were at lower odds for use. Lifetime use of other substances including cannabis (aOR = 28.4, 95% CI: 17.1-47.2), ketamine (aOR = 10.9, 95% CI: 1.63-73.4), LSD (aOR = 3.82, 95% CI: 1.98-7.37), cocaine (aOR = 3.77, 95% CI: 2.54-5.59), psilocybin (aOR = 3.29, 95% CI: 1.75-6.16), prescription opioids (aOR = 2.43, 95% CI: 1.44-4.09), and prescription stimulants (aOR = 1.96, 95% CI: 1.29-2.99) were associated with increased odds of ecstasy/MDMA use. We estimated that over 1 in 20 AAPI adults have ever used ecstasy/MDMA. Variations by age, sex, family income, substance type, and mental health service utilization emphasize the need for targeted public health strategies.

Stepped wedge cluster randomized trials (SWCRTs) often face challenges related to potential confounding by time. Traditional frequentist methods may not provide adequate coverage of an intervention's true effect using confidence intervals, whereas Bayesian approaches show potential for better coverage of intervention effects. However, Bayesian methods remain underexplored in the context of SWCRTs. To bridge this gap, we propose two innovative Bayesian hierarchical penalized spline models. Our first model accommodates large numbers of clusters and time periods, focusing on immediate intervention effects. To evaluate this approach, we compared this model to traditional frequentist methods. We then extend our approach to account for time-varying intervention effects, conducting a comprehensive comparison with an existing Bayesian monotone effect curve model and alternative frequentist methods. The proposed models were applied in the Primary Palliative Care for Emergency Medicine stepped wedge trial to evaluate the effectiveness of the intervention. Through extensive simulations and real-world application, we demonstrate the robustness of our proposed Bayesian models. Notably, the Bayesian immediate effect model consistently achieves the nominal coverage probability, providing more reliable interval estimations while maintaining high estimation accuracy. Furthermore, our proposed Bayesian time-varying effect model represents a significant advancement over the existing Bayesian monotone effect curve model, offering improved accuracy and reliability in estimation while also achieving higher coverage probability than alternative frequentist methods. To the best of our knowledge, this marks the first development of Bayesian hierarchical spline modeling for SWCRTs. Our proposed models offer promising tools for researchers and practitioners, enabling more precise evaluation of intervention impacts.

UNLABELLED:Exposures to phthalates and synthetic phenols are common among expectant mothers in the US. Previous studies on the neurotoxicity of these compounds have primarily assessed the effects of individual compounds on child behavior, but have not assessed potential combined effects of these substances. We assessed associations between prenatal exposure to a mixture of phthalates and phenols with behavioral problems among preschool-age children participating in the Environmental influences on Child Health Outcome (ECHO) Program. The study sample included 878 mother-child pairs from three cohorts with data on urinary concentrations of 10 phenols and 11 phthalate metabolites during pregnancy, along with caregiver reported Child Behavioral Checklist Ages 1½ to 5 (CBCL) data. Using covariate-adjusted weighted quantile sum (WQS) regression, we estimated associations between the phenol - phthalate mixture and CBCL behavioral scales T-scores. We fitted additional models stratified by sex due to previous reports of sex-specific associations. No statistically significant associations were observed in the overall sample when both male and female children were combined. However, in males, a quintile increase in the WQS index was associated with a 0.04 (95% CI: 0.00; 0.08) higher T-score of externalizing problems. The major contributors to this mixture effect were butylparaben (with a weight of 21%), benzophenone-3 (15%) and MCNP (11%). Conversely, in females, significant negative associations were observed between the WQS index with the total behavioral problems scale (beta = −0.05, 95% CI: −0.09; −0.01), externalizing problems (beta = −0.06, 95% CI = −0.10; −0.02) and internalizing problems (beta = −0.04, 95% CI: −0.08; −0.00). CONCLUSION::Our findings suggest that exposure to synthetic phenols and phthalate metabolite mixtures during pregnancy may impact childhood externalizing behavior with distinct associations in males and females. These findings contribute to the existing evidence on the combined effects of these compounds during development, emphasizing the need for further research on the combined effects of these mixtures.

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.

OBJECTIVE:This study aimed to identify facilitators and barriers among sexual and gender minority (SGM) individuals in receiving reproductive healthcare. METHODS:Participants were recruited through social media and university groups across the US. Inclusion criteria consisted of self-identified SGM community members; aged 18-40. This included: cisgender women whose sexual orientation included gay, lesbian, bisexual, and/or queer and / or individuals whose gender identity does not align with their sex assigned at birth; transgender men, non-binary people with a uterus, cisgender queen woman, and transgender woman. An initial codebook was developed utilizing inductive coding to identify key themes. RESULTS:A total of 9 focus groups were held with 67 people,5-10 people per group. Six themes were identified: 1) Barriers to high quality reproductive care, 2) Facilitators to high quality reproductive care, 3) Negative prior experiences, 4) Physical/logistical access to adequate care, 5) Emotions/trust in disclosing SGM status, and 6) Knowledge levels on SGM reproductive healthcare. CONCLUSION/CONCLUSIONS:Quality reproductive health care for SGM individuals is hindered by individual, clinician, and institutional factors. The factors include individual barriers of knowledge, distrust, and dysphoria; clinician barriers knowledge gaps or discomfort; and institutional factors of false advertising of LGBTQ+ friendly practices. PRACTICE IMPLICATIONS/CONCLUSIONS:This study impacts clinical practice through providing focused areas to better improve training and education for healthcare providers. Findings support improving clinical training on cultural humility, creating a welcoming environment, maintaining trust, and utilizing sensitive terminology.

INTRODUCTION/BACKGROUND:Research has demonstrated that food insecurity during childhood is associated with worse physical and mental health in childhood. However, little is known about how food insecurity during childhood impacts health outcomes in young adulthood. METHODS:This study analyzed data from the Future of Families and Child Wellbeing Study (2024), a longitudinal birth cohort study of children born in 1998-2000. Childhood food insecurity trajectory groups from age 3 to 15 years were identified using group-based trajectory modeling. Associations between childhood food insecurity trajectory groups and young adult weight (BMI, overweight status, and obese status) and high self-reported health (good/excellent) at age 22 were modeled with multivariate linear and logistic regression. RESULTS:Three trajectories were identified among 4,296 participants: 66.9% were food secure, 7.5% were food insecure, and 25.6% transitioned from being food insecure-to-secure throughout childhood. In adjusted analyses, young adults assigned to the food insecure-to-secure trajectory group as children had higher BMI (B 0.82, 95% CI [0.07-1.58]) and higher odds of overweight status (OR 1.24, 95% CI [1.01-1.52]) than young adults assigned to the food secure trajectory group as children. Young adults in the food insecure trajectory group as children had lower odds of high self-reported health than those in the food secure trajectory group as children (OR 0.65, 95% CI [0.48-0.89]). CONCLUSIONS:Food insecurity in childhood is associated with high weight status and poor self-reported health in young adulthood. These findings highlight the importance of childhood food insecurity screening and interventions to promote health throughout the life course.

BACKGROUND/UNASSIGNED:Many barriers prevent transgender women (TW) from fertility preservation (FP) prior to initiating gender-affirming hormones. The decision to move forward with gender affirming bottom surgery presents the last opportunity for these patients to preserve their ability to have genetically related children. However, oftentimes these patients will have azoospermia even after stopping their hormone therapy for an extended period due to the negative effects of these hormones on fertility. The objective of this case report is to investigate a novel method of FP in TW on longstanding gender-affirming hormone therapy who present with azoospermia on conventional semen analysis. CASE DESCRIPTION/UNASSIGNED:Three TW on gender-affirming hormone therapy for between 6-21 years presented for FP prior to gender affirming vaginoplasty with simultaneous orchiectomy. All three patients had azoospermia on conventional semen analysis. Extended sperm search and microfreeze (ESSM) was conducted on semen samples. Results, including sperm count, number of vitrified sperm, and number of SpermVDs, were obtained. Conventional testicular sperm extraction (TESE) was also performed on two of the patients. Two out of three patients successfully retrieved and cryopreserved sperm after ESSM procedure. One patient had a successful ESSM despite not having any sperm on testicular tissue analysis. CONCLUSIONS/UNASSIGNED:The findings from this case study underscore the potential use for ESSM as a tool for FP in TW who have undergone multiple years of hormonal therapy and have unsuccessful semen analyses and testicular extractions. Future studies with larger cohorts are necessary to validate the efficacy of ESSM and explore its potential application as a standard practice in transgender healthcare, particularly for those who cannot completely cease hormone therapy.
