The Relationship Between Gut Microbiota, Muscle Mass and Physical Function in Older Individuals: A Systematic Review.

Background: Recent evidence suggests that sarcopenia and subsequent changes in muscle mass and functional outcomes are linked to disruption to the gastrointestinal microbiota composition and/or function via the microbiota-gut-muscle axis. Despite growing interest, few studies have systemically analysed (1) the relationship between the gut microbiota, muscle mass and physical performance and (2) the effects of gut-modulating dietary interventions on these outcomes within older individuals with or without sarcopenia.

Methods: Four electronic databases (PubMed, MEDLINE, Embase and Scopus) were searched for articles published from the year 2004 until July 2023.

Perspectives on vaccination among unvaccinated members of a Canadian indigenous population.

From the beginning of the COVID-19 pandemic, the potential impact on Indigenous (First Nations, Métis and Inuit) communities in Canada was a major concern. Evidence from previous pandemics, particularly H1N1, suggested that more cases and poorer outcomes among Indigenous Peoples was likely and that there might be barriers to Indigenous Peoples' vaccination. In this short report we consider the non-vaccination decisions of a sample of unvaccinated Métis Nation of Ontario citizens.

Investigating the origins of the mutational signatures in cancer.

Most of the risk factors associated with chronic and complex diseases, such as cancer, stem from exogenous and endogenous exposures experienced throughout an individual's life, collectively known as the exposome. These exposures can modify DNA, which can subsequently lead to the somatic mutations found in all normal and tumor tissues. Understanding the precise origins of specific somatic mutations has been challenging due to multitude of DNA adducts (i.

Etiology and correlates of alcohol misuse in early midlife.

Background: Early midlife individuals (ages 30-40) experience demographic shifts that may influence the remainder of adult life. Although new or persistent alcohol misuse is common during this period, early midlife is understudied in alcohol use literature. We examined the heritability of alcohol misuse; the associations between alcohol misuse and sociodemographic factors, physical health, and well-being; and whether these associations were robust in cotwin comparisons.

Could point-of-care bioimpedance analysis be another tool in the prevention of osteoporotic fractures?

A treatment gap exists in osteoporosis, with people at risk of fracture often not identified. Dual X-Ray Absorptiometry is the gold standard technique for the identification of low bone mass, but it is not always easily accessible. Bioimpedance analysis (BIA) is a non-invasive, safe and portable technology, which can provide a calculated estimate of bone mass.
