Introducing the Cochrane Nutrition & Physical Activity Thematic GroupImproving nutrition and physical activity is a global health priority. Within Cochrane’s new production model, Thematic Groups (TG) with specialist content and review methods expertise have been established. The purpose of TGs is to support the development and dissemination of high-quality evidence syntheses on priority issues.

Brain iron concentration in childhood ADHD: A systematic review of neuroimaging studiesIron deficiency may play a role in the pathophysiology of Attention Deficit/Hyperactivity Disorder (ADHD). Due to its preponderant function in monoamine catecholamine and myelin synthesis, brain iron concentration may be of primary interest in the investigation of iron dysregulation in ADHD.

Mitochondrial mistranslation modulated by metabolic stress causes cardiovascular disease and reduced lifespanChanges in the rate and fidelity of mitochondrial protein synthesis impact the metabolic and physiological roles of mitochondria. Here we explored how environmental stress in the form of a high-fat diet modulates mitochondrial translation and affects lifespan in mutant mice with error-prone or hyper-accurate mitochondrial ribosomes. Intriguingly, although both mutations are metabolically beneficial in reducing body weight, decreasing circulating insulin and increasing glucose tolerance during a high-fat diet, they manifest divergent (either deleterious or beneficial) outcomes in a tissue-specific manner.

Prebiotic Supplementation During Pregnancy Modifies the Gut Microbiota and Increases Metabolites in Amniotic Fluid, Driving a Tolerogenic Environment In UteroThe gut microbiota is influenced by environmental factors such as food. Maternal diet during pregnancy modifies the gut microbiota composition and function, leading to the production of specific compounds that are transferred to the fetus and enhance the ontogeny and maturation of the immune system. Prebiotics are fermented by gut bacteria, leading to the release of short-chain fatty acids that can specifically interact with the immune system, inducing a switch toward tolerogenic populations and therefore conferring health benefits.

Variation in Neonatal Nutrition Practice and Implications: A Survey of Australia and New Zealand Neonatal UnitsSignificant global variation exists in neonatal nutrition practice, including in assigned milk composition values, donor milk usage, fortification regimens, probiotic choice and in methods used to calculate and report nutrition and growth outcomes, making it difficult to synthesize data to inform evidence-based, standardized nutritional care that has potential to improve neonatal outcomes

The Association Between Breakfast Skipping and Positive and Negative Emotional Wellbeing Outcomes for Children and Adolescents in South AustraliaThe prevalence of child and adolescent breakfast skipping is concerning, and limited existing evidence suggests an association between skipping breakfast and negative emotional wellbeing outcomes. However, positive emotional wellbeing outcomes have been neglected from research in this space.

Caregiver perspectives regarding the impact of feeding difficulties on mealtime participation for primary school-aged autistic children and their familiesAlthough up to 89% of autistic children experience feeding difficulties, little is known about the impact of these difficulties on mealtime participation. The aim of this study was to explore the impact of feeding difficulties on the mealtime participation of autistic children and their families based on caregiver experiences.

Teaching Kitchens: An innovative program for enhancing self-management skills in adolescents living with type 1 diabetes (T1D) – A feasibility studyAdolescents living with type 1 diabetes (T1D) are faced with unique challenges to nutrition management. The current Perth Children's Hospital (PCH) T1D management model includes individualised education at diagnosis and annual reviews. Currently, no group education is provided to develop self-management skills for healthy meal preparation. Teaching Kitchens offers a skills-based program in food literacy and nutrition. This feasibility study explored if a Teaching Kitchens program at PCH engaged adolescents aged between 13 and 17 years, living with T1D.

Restricting outdoor advertising of unhealthy food: can Australia's food category-based classification system be applied consistently?Most outdoor food advertising (e.g. billboards and bus stops) features foods that are considered unhealthy. The most important technical challenge when designing policies to restrict unhealthy outdoor food advertising is defining 'unhealthy food'. To date, most restriction policies have used nutrient profiling models (i.e. foods are classified according to their nutritional composition) to determine which foods and beverages may be advertised. In Australia, state governments have endorsed a food category-based classification system, with no prescribed nutrient limits, which may create ambiguity when multiple users are identifying food advertisements to be restricted.
