Neighborhood Factors as Correlates of Alcohol Use in the N2 Cohort Study of Black Sexually Minoritized Men and Transgender Women.

Sexually minoritized men (SMM), transgender women (TW), and particularly Black SMM and Black TW may be disproportionately impacted by alcohol-related problems. Few studies have empirically examined neighborhood factors that may contribute to alcohol use, specifically among these populations. Using data from the N2 longitudinal cohort study in Chicago, IL, survey data from the second wave of longitudinal assessment (n = 126) and GPS mobility data from enrollment were used to evaluate neighborhood alcohol outlet availability, neighborhood disorder, and neighborhood poverty as correlates of individual alcohol use.

Extending the Calgary Audit and Feedback Framework into the virtual environment: a process evaluation and empiric evidence.

Background: The Calgary Audit and Feedback Framework (CAFF) is a pragmatic, evidence-based approach for the design and implementation of in-person social learning interventions using Audit and Group Feedback (AGF). This report describes extension of CAFF into the virtual environment as part of a multifaceted intervention bundle to reduce redundant daily laboratory testing in hospitals. We evaluate the process of extending CAFF in the virtual environment and share resulting evidence of participant engagement with planning for practice change.

Three limited interaction approaches to understanding the epidemiology of HIV among YMSM in the US.

Background: Using a theoretically-grounded approach to the epidemiological study of HIV incidence among a national, diverse sample of sexual and gender minority (SGM) men (age 17 -29 years), as well as examining HIV incidence through an innovative geospatial lens, is of considerable public health significance. Our overarching objectives are to assemble a U.S.

Changes in Hippocampal Volume after Traumatic Brain Injury (TBI).

Objective: To investigate hippocampal volume changes in moderate to severe traumatic brain injury (TBI) patients compared to healthy controls and assess their association with post-traumatic epilepsy (PTE), focusing on age-related effects.

Methods: Imaging and demographic data for TBI patients were obtained from the Epilepsy Bioinformatics Study for Antiepileptogenic Therapy (EpiBioS4Rx) database; healthy controls matched by age and sex were sourced from Alzheimer's Disease Neuroimaging Initiative (ADNI), the National Institute of Mental Health (NIMH) Intramural Healthy Volunteer Dataset, the Parkinson's Progression Markers Initiative (PPMI), and the Autism Brain Imaging Data Exchange (ABIDE). MRI images for TBI subjects were obtained within 14-32 days post-injury.

Boron-induced transformation of ultrathin Au films into two-dimensional metallic nanostructures.

The synthesis of large, freestanding, single-atom-thick two-dimensional (2D) metallic materials remains challenging due to the isotropic nature of metallic bonding. Here, we present a bottom-up approach for fabricating macroscopically large, nearly freestanding 2D gold (Au) monolayers, consisting of nanostructured patches. By forming Au monolayers on an Ir(111) substrate and embedding boron (B) atoms at the Au/Ir interface, we achieve suspended monoatomic Au sheets with hexagonal structures and triangular nanoscale patterns.
