Mare colostrum quality and relationship with foal serum immunoglobulin G concentrations and average daily weight gains.

Background: Foals suffer from total failure to transfer passive immunity (TFTPI) when serum immunoglobulin (IgG) is <4 g/L, and partial failure to transfer passive immunity (PFTPI) when serum IgG is 4-8 g/L.

Objectives: To explore risk factors for poor serum IgG concentration.

Study Design: Retrospective observational study.

Across the multiverse: exploring a diverse set of specifications related to cross-sectional and prospective associations between adolescent alcohol use and emotional problems.

Background: The relationship between adolescent alcohol use and emotional problems remains unclear and contradictory. These inconsistencies may in part be due to differences in the measurement and operationalization of alcohol use and emotional problems across studies, as well as confounder selection and missing data decisions. This study explores the associations between common specifications of adolescent alcohol use and emotional problems in a large sample of adolescents.

Process evaluation of the digital Health4Life intervention among a sample of disadvantaged adolescents and teachers.

Disadvantaged adolescents, including those from lower socioeconomic status (SES) or geographically remote backgrounds, engage in higher rates of risk behaviours, including poor diet, alcohol and tobacco use. While digital interventions targeting lifestyle risk behaviours show potential, few studies have focused on their implementation and relevance for this population. This study conducted a process evaluation of 'Health4Life', a universal school-based digital program targeting multiple behaviours, among a sample of disadvantaged adolescents.

Adolescent behavioural intentions: Secondary outcomes from a cluster randomized controlled trial of the Health4Life school-based lifestyle modification intervention.

Intervention: Health4Life: a school-based eHealth intervention targeting multiple health behaviour change (MHBC).

Research Question: Does Health4Life impact secondary outcomes of self-reported intentions regarding six lifestyle behaviours in adolescents (alcohol use, tobacco smoking, screentime, physical activity, discretionary beverage consumption, and sleep)?

Methods: We implemented a cluster randomized controlled trial within secondary schools across three Australian states. Schools were randomly assigned (1:1) to receive either the Health4Life intervention, which consisted of a six-module, web-based program and accompanying smartphone app, or an active control (standard health education).

A mixed-methods study among adolescents and teachers in Bogotá, Colombia: adapting the OurFutures Alcohol Program.

Early onset of alcohol consumption among Colombian adolescents highlights the need for effective and accessible preventive interventions. This project aimed to conduct formative work to inform the adaptation of an effective eHealth alcohol use prevention program originally developed in Australia, the OurFutures Alcohol Module, to the Bogotá context. Twenty-six adolescents and 10 teachers in Bogotá participated in the study.
