Does disability modify the association between poor mental health and violence victimisation over adolescence? Evidence from the CoVAC cohort study in Uganda.

We aimed to estimate the impact of poor mental health in early adolescence on subsequent poor mental health, depression, and violence victimisation in late adolescence and to determine whether young people living with disabilities experienced a stronger relationship between mental health and these outcomes. Data from two waves of a longitudinal cohort study of 2773 Ugandan adolescents were used to assess the impact of mental health difficulties in early adolescence (aged 11-14) on presence of subsequent mental health difficulties, depression and past year violence victimisation in later adolescence (aged 15-18). We used g-computation to examine how these outcomes changed dependent on levels of poor mental health in early adolescence and explored functional difficulties as an effect modifier.

High-affinity chimeric antigen receptor signaling induces an inflammatory program in human regulatory T cells.

Regulatory T cells (Tregs) are promising cellular therapies to induce immune tolerance in organ transplantation and autoimmune disease. The success of chimeric antigen receptor (CAR) T cell therapy for cancer has sparked interest in using CARs to generate antigen-specific Tregs. Here, we compared CAR with endogenous T cell receptor (TCR)/CD28 activation in human Tregs.

Transcytosis as a Mechanism of HIV-1 Entry into Columnar Epithelial Explants of the Female Reproductive Tract.

During male-to-female transmission, HIV-1 must cross the mucosal epithelium of the female reproductive tract to gain access to underlying target cells. Previously, we demonstrated that HIV-1 can penetrate intact columnar and squamous genital epithelia in both and systems. We found that the virus enters the squamous epithelium via a diffusion-based mechanism, but the mechanism of entry in columnar epithelium remained elusive.

Creating a plasma coordination center to support COVID-19 outpatient trials across a national network of hospital blood banks.

Introduction: In response to the COVID-19 pandemic, we rapidly implemented a plasma coordination center, within two months, to support transfusion for two outpatient randomized controlled trials. The center design was based on an investigational drug services model and a Food and Drug Administration-compliant database to manage blood product inventory and trial safety.

Methods: A core investigational team adapted a cloud-based platform to randomize patient assignments and track inventory distribution of control plasma and high-titer COVID-19 convalescent plasma of different blood groups from 29 donor collection centers directly to blood banks serving 26 transfusion sites.
