This article reports the trends in BMI score (-BMI) and their correlation with insulin dose and A1C in children with new-onset type 1 diabetes from several Latin American centers. The researchers observed a significant increase in the -BMI from type 1 diabetes onset through the 3-year follow-up, with insulin dose as a significant covariate. Although insulin doses steadily increased, their impact on A1C did not appear to be optimal (mean A1C 8.

Global elimination of chronic hepatitis C (CHC) remains difficult without an effective vaccine. Since injection drug use is the leading cause of hepatitis C virus (HCV) transmission in Western Europe and North America, people who inject drugs (PWID) are an important population for testing HCV vaccine effectiveness in randomized-clinical trials (RCTs). However, RCTs in PWID are inherently challenging.

This project report explores the use of a Health in All Policies (HiAP) approach by the Georgia Health Policy Center (GHPC) to integrate health perspectives into affordable housing policy and practice in Georgia. It focuses on five interconnected projects from over a decade-long collaboration to illustrate how the GHPC team started with a Health Impact Assessment (HIA) to seed cross-sector partnerships and then sustained them through subsequent collaborations. These projects included comprehensive-, intermediate-, and rapid-scale HIAs, as well as direct collaborations on housing development funding applications and a multidisciplinary research study on public housing renovations.

Sport-based youth development programs, delivered through campus-community partnerships, can create impactful experiences for college students, meet university objectives, and improve the health of children in under-resourced rural communities. This study aimed to pilot test intervention mapping (IM), a systematic approach to intervention development and implementation, to refine the Hoosier Sport intervention, which is a local public health initiative that utilizes the Obesity-Related Behavioral Intervention Trials (ORBITs) model to improve physical activity in middle school children. The IM process, which included a diverse IM planning and advisory group of university representatives and local schools, was guided by self-determination theory (SDT) and social cognitive theory (SCT) and followed four steps: Logic Model of the Problem, Logic Model of Change, Program Design, and Program Production.

Designing and carrying out a controlled human infection (CHI) model for hepatitis C virus (HCV) is critical for vaccine development. However, key considerations for a CHI model protocol include understanding of the earliest viral-host kinetic events during the acute phase and susceptibility of the viral isolate under consideration for use in the CHI model to antiviral treatment before any infections in human volunteers can take place. Humanized mouse models lack adaptive immune responses but provide a unique opportunity to obtain quantitative understanding of early HCV kinetics and develop mathematical models to further understand viral and innate immune response dynamics during acute HCV infection.
