INTRODUCTION/BACKGROUND:Black sexually minoritized men and gender-expansive people (SGM), including transgender women, have higher levels of alcohol use and experience greater negative consequences from alcohol consumption than the general population. We investigated the role of multilevel factors contributing to alcohol use among these groups. METHODS:We analyzed data collected from HIV-negative participants in the Neighborhoods and Network (N2) cohort study in Chicago, IL (N = 138). Participants completed a social network inventory (November 2018-April 2019) and reported alcohol use (frequency, quantity, and frequency of binge drinking) during a quantitative assessment. We used stepwise negative binomial regression to identify associations with social network and individual-level alcohol use while controlling for sociodemographic variables. RESULTS: = 2.7), of whom 93% were Black and 78% were friends/family. Among the confidants, 30% drank alcohol at least several times per week. Identifying as Latine (RR = 2.21; 95% CI: 1.44-3.10), having a higher Generalized Anxiety Disorder-7 score (RR = 1.03; 95%CI: 1.00-1.05), living with a problem drinker during one's childhood (RR = 1.80; 95% CI: 1.39-2.34), and having a greater proportion of regular drinkers in one's social network (RR = 1.49; 95% CI: 1.02-2.17) were positively associated with alcohol use. CONCLUSION/CONCLUSIONS:Black SGM exposed to social network alcohol use during childhood and adulthood reported increased alcohol use. Interventions targeting Black SGM should address social norms around alcohol, intersectional discrimination, and mental health.

BACKGROUND/UNASSIGNED:Chronic pain affects 20.5% of the US population, costing $296 billion annually in lost productivity. Spinal cord stimulation (SCS) has become a key treatment for refractory neuropathic and nociceptive pain, with increasing usage due to technological advancements. However, the durability of SCS therapy, including explantation rates, remains a concern. Understanding explantation causes is essential for improving patient selection and device effectiveness. This study aims to analyze SCS explantation rates and reasons, as well as evaluate the financial burden of these procedures on the healthcare system. METHODS/UNASSIGNED:Three primary screening methods were used: manual search with keywords, MeSH term query, and reference list screening. The search covered PubMed, Cochrane, and Web of Science databases from inception to November 2024, yielding 719 articles. After applying eligibility criteria, 72 articles were identified, and 25 were selected for analysis. Data extraction was done by independent reviewers, with a second reviewer ensuring accuracy. Discrepancies were resolved by the corresponding editor. RESULTS/UNASSIGNED:We reviewed data from 13,026 patients who underwent permanent SCS implantation between 1984 and 2024, across 25 studies. A total of 1882 patients (9.82%) underwent explantation. The most common reason was lack of efficacy and inadequate pain relief (38%), followed by lead failure (15%) and infection (14%). While SCS is generally effective, issues related to device longevity and patient satisfaction persist, with explantation rates due to technical failures and lack of efficacy being concerns. CONCLUSION/UNASSIGNED:SCS efficacy varies, with explantation rates reaching up to 38%, often due to inadequate pain relief. Most explantations occur within the first year, despite SCS being a safe and effective treatment. High implantation costs ($35,000 to $70,000) and revision costs ($15,000 to $25,000) raise concerns among payors. The hardware-driven model limits waveform flexibility, highlighting the need for innovation.

Low-dose oral minoxidil (LDOM) has emerged as a widely used off-label treatment for different types of alopecia, showing a favorable safety profile and effectiveness. Despite its growing use, it is essential to understand the possible associated adverse events (AEs) and their appropriate management to optimize this therapy. The aim of this article was to comprehensively review the AEs of LDOM treatment, describing their frequency, risk factors, affected anatomical sites, and management strategies. A search in the PubMed and EMBASE databases was performed for studies published before 31 December 2024, reporting the treatment of any type of hair loss with oral minoxidil. The most frequent AE is hypertrichosis, occurring in approximately 15% of patients, with a higher incidence in women and patients with higher doses. Fluid retention affects 1.3-10% of patients, particularly women, and typically occurs within 1-3 months of treatment. Other cardiovascular AEs, such as tachycardia or dizziness, occur in fewer than 5% of cases and are usually mild and transient. Severe AEs, including pericardial effusion, are extremely rare and often linked to compounding errors comprising an excessive dose. Management strategies include dose reduction, pharmacological interventions like diuretics for edema, and lifestyle measures such as sodium restriction. In most cases, AEs resolve without the need for treatment discontinuation. The favorable safety profile of LDOM makes it a valuable therapeutic option for alopecia, though careful patient selection, dose titration, and monitoring are essential to minimize risks.

Disability education is limited in medical training, leading to physician misconceptions and discomfort when caring for patients with disabilities. The team sought to develop an elective course to improve medical students' disability cultural competency and advocacy skills. The team performed a targeted needs assessment including curriculum mapping and interviews with community members with disabilities to develop course learning objectives based on gaps in the medical school curricula and identified themes from the interviews. The elective course entitled Justice, Equity, Diversity, and Inclusion (JEDI)-Minded for Disability included five sessions and was administered in 2023 and 2024 with eleven participants. The team administered an eleven item pre- and post-course self-assessment on a five-point Likert scale as well as free response questions. Improvement in self-reported confidence was noted on all post-course assessment items. Student takeaways included increased understanding of barriers to care and health disparities and ways to advocate for their future patients with disabilities. Through the novel inclusion of community members with disabilities in course development, the team ensured content remained relevant and highlighted the lived expertise of people with disabilities. Importantly, this elective increased student knowledge of disability and health disparities and empowered students to advocate for people with disabilities.

Parenting in very early childhood (0-2 years) provides important context for children's socioemotional development. The present study aims to address limitations of extant parenting literature, namely the reliance on white, middle-class samples and use of variable-centered approaches that often mask the rich heterogeneity of parenting styles. Using data from an efficacy trial of a tiered parenting program to promote school readiness, the current study examined parenting styles across three waves when children were 6, 18, and 24 months with a sample of Black/African American and Latina mothers with low incomes using person-oriented, latent class analysis. Based on multiple fit indices and interpretability, a three-class model was found to best fit the data. Two of the three parenting classes were identified for both Black/African American and Latina groups across all three ages: one was characterized by high levels of sensitivity, positive regard, and language quality/quantity (High Support and Warmth) and the other was characterized by moderate levels of these indicators (Moderate/Low, Moderate, and Moderate/High Support and Warmth). The third class varied the most between groups and over time. For Black/African American mothers, the third class was characterized most notably by the level of directiveness (ranging from High at 6 months, Moderate at 18 months, and Low at 24 months). For Latina mothers, this class was characterized by varying levels of directiveness and stimulation that were High at 6 months and Moderate at 18 and 24 months. Within most classes, mean levels of parenting behaviors varied by age. Findings emphasize the importance of considering age, culture, and time when assessing maternal parenting from infancy to toddlerhood.

Somatic-type malignancies (SMs) arising in germ cell tumors (GCTs) are aggressive neoplasms resistant to systemic treatment. Most are diagnosed in metastatic sites after chemotherapy; however, they have also been well-documented in primary testicular GCTs. Historically, SMs were thought to originate in components of teratoma that acquire molecular alterations equivalent to those that characterize their true somatic counterparts. However, recent studies have shown that SMs typically lack the hallmark molecular alterations seen in similar somatic tumors. Additionally, clinicopathologic and molecular data suggest that a subset may derive from yolk sac tumor (YST) rather than teratoma. In this study, we evaluated the relationship between conventional histological types of GCTs and SMs by comparing expression of microRNA (miR)-371-373 and genomic methylation profiles. A total of 96 samples (including multiple paired conventional GCT-SM samples from individual tumors) were assessed for miR-371-373 expression by RT-qPCR and genomic DNA methylation using a clinically validated assay. Expression of miR-371-373 was higher in conventional GCTs than in SMs (considered as a single category encompassing all histological subtypes). However, miR-371-373 expression was heterogeneous among SMs, with significantly higher levels in sarcomatoid YST (SYST) and glandular neoplasms than in other SMs. Genomic DNA methylation analysis showed that SMs (considered as a single category) did not form a distinct cluster. Instead, they grouped into multiple clusters that did not show perfect correspondence with histology and often included conventional GCTs. Genome-wide methylation assessment showed a higher abundance of hypermethylated regions in SMs than in conventional GCTs. Analysis of paired conventional GCT and 'somatic-type' components that did not meet size criteria for SMs dissected from individual tumors demonstrated separation according to histology, suggesting that epigenetic processes play a role in the transition from conventional GCT to 'somatic-type' phenotypes. Gene-level and pathway-level analyses identified MAPK/RAS signaling, mitosis/proliferation, differentiation towards neural tissue/neuroectoderm, epithelial-to-mesenchymal transition, and DNA repair as key differentially regulated processes in components with somatic-type histology, suggesting mechanisms of progression from conventional to 'somatic' phenotypes in GCT. These results support the hypothesis that a subset of SMs derive from YST and suggest that some subtypes (such as SYST) may represent 'intermediate' phenotypes. Additionally, analysis of differentially methylated promoter regions in SM identified genes and biologic processess that may underlie 'somatic tranformation' in GCTs. © 2025 The Author(s).

Facial trauma presents a significant healthcare challenge in low- and middle-income countries (LMICs) due to limited access to specialized surgical care. This case report describes the management of a complex forehead degloving injury in a 20-year-old woman in Somalia, highlighting the role of remote surgical mentorship in resource-limited settings. The patient sustained a right forehead degloving injury in a motor vehicle collision, exposing a 3 × 5 cm segment of the frontal bone. Initial debridement resulted in a large soft-tissue defect, and the local surgical team faced challenges in selecting an optimal reconstructive approach due to limited experience and resources. The patient's aesthetic concerns further complicated decision-making. Through the Surgeons in Humanitarian Alliance for Reconstruction, Research, and Education program, the team sought virtual expert consultation via a secure WhatsApp platform. Based on expert recommendations, conservative management with daily Vaseline dressings was initiated to promote granulation tissue formation. Over 6 weeks, complete bone coverage was achieved, followed by full-thickness skin grafting, resulting in a satisfactory aesthetic outcome. This case demonstrates the value of global surgical networks in guiding complex reconstructions in LMICs, allowing local teams to deliver high-quality care despite resource constraints. Although short-term results were successful, long-term follow-up is necessary to assess functional and aesthetic durability. The success of this case underscores the importance of international collaborations in improving surgical education, patient outcomes, and sustainability of reconstructive techniques in LMICs.
