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.

Introduction: The social connections surrounding children and adolescents support them in facing challenges and seeking help, ultimately acting as a protective factor in their mental, physical, and behavioral health outcomes across the life course. In complex contexts of political instability and dislocation, these social resources are often fractured, strained, or altogether unavailable, which restricts access to essential services and affects outcomes for these populations. This study aims to identify, characterize, and visually depict social connections related to the health and well-being needs of children and adolescents affected by displacement in Lebanon, by pilot testing the Participatory Assessment Tool for Mapping Social Connections (PATMSC).

Teaching assistants (TAs) play a significant role in students' learning environment and experience but receive limited training in the non-curricular aspects of teaching and student support. Graduate students frequently engage in near-peer teaching, with student teachers with one or more years' experience compared to learners engaged in a structured teaching role. Academic institutions may perpetuate racism and its effects on health through institutional norms and pedagogy; training TAs to foster inclusive learning environments is therefore essential.

PET analysis is conventionally performed as a two-stage process of quantification followed by analysis. We recently introduced SiMBA (Simultaneous Multifactor Bayesian Analysis), a hierarchical model that performs quantification and analysis for all brain regions of all individuals at once, and in so doing improves both the accuracy of parameter estimation as well as inferential efficiency. However until now, SiMBA has only been implemented for the two-tissue compartment model.

Background/objective: In a subset of participants from the CALERIE Phase 2 study we evaluated the effects of 2y of ~25% Calorie Restriction (CR) diet on IgG N-glycosylation (GlycAge), plasma and complement C3 N-glycome as markers of aging and inflammaging.

Methods: Plasma samples from 26 participants in the CR group who completed the CALERIE2 trial and were deemed adherent to the intervention (~>10 % CR at 12 mo) were obtained from the NIA AgingResearchBiobank. Glycomic investigations using UPLC or LC-MS analyses were conducted on samples from baseline (BL), mid-intervention (12 mo) and post-intervention (24 mo), and changes resulting from the 2y CR intervention were examined.

Psychiatry Res

February 2025

Department of Psychiatry, New York State Psychiatric Institute, Columbia University Irving Medical Center, New York, NY, USA; Department of Epidemiology, Columbia University Mailman School of Public Health, New York, NY, USA.

Background: Maternal nutritional deficiency is linked with several adverse outcomes in offspring but the link between maternal vitamin B12 levels and offspring schizophrenia remains unexplored.

Methods: In this nationwide population-based nested case-control design, 1145 schizophrenia cases were born between 1987-1997 and diagnosed by 2017 and each case were matched with a control. Maternal vitamin B12 levels during the first and early second trimesters of pregnancy were measured using chemiluminescence microparticle immunoassay from maternal sera.

Exercise as Mitochondrial Medicine: How Does the Exercise Prescription Affect Mitochondrial Adaptations to Training?

Annu Rev Physiol

December 2024

2Division of Behavioral Medicine, Department of Psychiatry, Columbia University Irving Medical Center, Columbia University, New York, NY, USA.

Mitochondria are multifaceted organelles with several life-sustaining functions beyond energy transformation, including cell signaling, calcium homeostasis, hormone synthesis, programmed cell death (apoptosis), and others. A defining aspect of these dynamic organelles is their remarkable plasticity, which allows them to sense, respond, and adapt to various stressors. In particular, it is well-established that the stress of exercise provides a powerful stimulus that can trigger transient or enduring changes to mitochondrial molecular features, activities, integrated functions, behaviors, and cell-dependent mitochondrial phenotypes.

Caloric restriction (CR) slows biological aging and prolongs healthy lifespan in model organisms. Findings from the CALERIE randomized, controlled trial of long-term CR in healthy, nonobese humans broadly supports a similar pattern of effects in humans. To expand our understanding of the molecular pathways and biological processes underpinning CR effects in humans, we generated a series of genomic datasets from stored biospecimens collected from n = 218 participants during the trial.

Introduction: There is growing interest in the relationship between neighborhood disadvantage and increased cannabis retail density, driven by evidence suggesting higher density is associated with increased cannabis use. Yet little is known on how this relationship varies across different measures of cannabis retail density. This study explores how measures of neighborhood advantage and disadvantage relate to four cannabis retail density measures in the US.

We investigated associations between neighborhood walkability and physical activity using twins (5477 monozygotic and same-sex dizygotic pairs) as "quasi-experimental" controls of genetic and shared environment (familial) factors that would otherwise confound exposure-outcome associations. Walkability comprised intersection density, population density, and destination accessibility. Outcomes included self-reported weekly minutes of neighborhood walking and moderate-to-vigorous physical activity (MVPA) and days per week using transit services (eg, bus, commuter rail).

The decolonise global health movement has critically reassessed the field's historical and political underpinnings, urging researchers to recognise biases and power imbalances through reflexivity and action. Genuine change is seen as the outcome of the researcher's self-awareness, often leaving the underlying structures of global health-and global mental health (GMH)-in the background. Here, we problematise how expectations around agency and change have been mobilised in discussions around decolonisation, highlighting the gradual and contingent nature of international collaboration in GMH.
