Background: Parental feeding practices may play a key role in dietary habits and nutritional status of adolescents, but research from adolescents' point of view on this topic is scarce.
Objective: To adapt and validate an instrument of parental feeding practices as perceived by adolescents in a Brazilian setting.
Methods: The Comprehensive Feeding Practices Questionnaire was translated into Portuguese and adapted to be answered by adolescents (ages 12 to 18). Content analysis and FACE validity to assess cultural equivalence was undertaken by experts in the adolescent nutritional and psychological fields. Pilot study was evaluated in 23 adolescents. The final version was administered to 41 students to assess instrument reproducibility (Intraclass Correlation Coefficient). Internal consistency (Cronbach's Alpha) and construct validity (Confirmatory Factor Analysis) were assessed in a third sample of 307 adolescents.
Results: Experts and adolescents considered content validity as appropriate. In reproducibility analysis (Intraclass Correlation Coefficient), 10 of the 12 factors were above 0.7. The factors "teaching about nutrition" and "food as reward" obtained values of 0.60 and 0.68, respectively. The Cronbach's Alpha of the whole scale was 0.83 and alphas for subscales ranged from 0.52 to 0.85; the factors "teaching about nutrition" and "food as a reward" had the lowest values (0.52). After removing these two factors, the Confirmatory Factor Analysis indicated that the structural model was appropriate. The final scale was made up of 10 factors with 43 questions.
Conclusions: The Comprehensive Feeding Practices Questionnaire-Teen demonstrates validity and reliability, and is a suitable tool to evaluate the perceptions of adolescents regarding parental feeding practices.

Introduction: Dysfunctional exercise (DEX) is common among individuals with an eating disorder (ED) and poses significant challenges to treatment and recovery. While safe and nutritionally supported physical activity can enhance treatment outcomes without hindering weight restoration, clinicians often hesitate to address DEX with their patients. This mixed-method study aimed to evaluate the impact of a Safe Exercise at Every Stage (SEES) informed training on clinician knowledge and self-efficacy in managing DEX during ED treatment.

Introduction: Antimicrobial resistance (AMR) is a growing threat to the efficacy of antimicrobials in humans and animals, including those used to control bovine respiratory disease (BRD) in high-risk calves entering western Canadian feedlots. Successful mitigation strategies require an improved understanding of the epidemiology of AMR. Specifically, the relative contributions of antimicrobial use (AMU) and contagious transmission to AMR emergence in animal populations are unknown.

Avoidant/restrictive food intake disorder (ARFID) can present with limited food variety, intake, or aversions. The symptoms can manifest at any age and typically appear in the first few years of life. The prevalence of ARFID varies widely among clinical and non-clinical populations, and its diagnosis requires trained health professionals to ensure early detection and prevention of poor outcomes.
