Response of the gut microbiome and metabolome to dietary fiber in healthy dogs.

Unlabelled: Dietary fiber confers multiple health benefits originating from the expansion of beneficial gut microbial activity. However, very few studies have established the metabolic consequences of interactions among specific fibers, microbiome composition, and function in either human or representative animal models. In a study design reflective of realistic population dietary variation, fecal metagenomic and metabolomic profiles were analyzed from healthy dogs fed 12 test foods containing different fiber sources and quantities (5-13% as-fed basis).

Design of allosteric modulators that change GPCR G protein subtype selectivity.

G protein-coupled receptors (GPCRs), the largest family of drug targets, can signal through 16 subtypes of Gα proteins. Biased compounds that selectively activate therapy-relevant pathways promise to be safer, more effective medications. The determinants of bias are poorly understood, however, and rationally-designed, G protein-subtype-selective compounds are lacking.

Prevalence of cognitive impairment and metabolic syndrome among older adults in calabar metropolis and the associated risk factors.

Background: The number of people reaching old age is rising, bringing an increase in age-related diseases like cardiovascular conditions and cognitive dysfunction. Cognitive impairment (CI) impacts various brain functions, affecting daily activities and quality of life. Metabolic syndrome (MetS), a cluster of cardiovascular risk factors, has been implicated in CI.

Patients' perspectives regarding health professionals contacting their relatives about genetic risk directly (with patient consent).

Genetic testing of blood relatives of individuals at high risk of dominant conditions has significant preventive health benefits. However, cascade testing uptake is <50%. Research shows increased testing uptake when health professionals (HPs) contact at-risk relatives directly, with patient consent.

COVID-19-related lockdowns and changes in overweight and obesity, movement behaviours, diet quality, and health-related quality of life among regional Australian primary school children: A repeat cross-sectional study.

Background: During the coronavirus disease 2019 (COVID-19) pandemic, the Australian state of Victoria (in particular, its capital, Melbourne) experienced some of the longest lockdowns in the world.

Objective: This repeated cross-sectional study examined changes between March to June 2019 (pre-pandemic) and April to August 2022 (6 to 11 months following pandemic-related lockdowns) in overweight and obesity prevalence, physical activity, sedentary behaviour, sleep, diet quality, and health-related quality of life (HRQoL) among primary school children in north-east Victoria, Australia.

Methods: Height and weight were measured for Grade 2, 4, and 6 students in 2019 (3889 children) and 2022 (1816 children).
