Measuring Food and Water Security in an Aboriginal Community in Regional Australia.

Objective: To measure current levels and experiences of food and water security in Walgett to guide a community-led program and to provide a baseline measure.

Design: A community-led cross-sectional survey conducted in April 2022 by trained local researchers.

Setting: Walgett, a regional town in NSW, Australia.

Quality Investigation of Pultruded Carbon Fiber Panels Subjected to Four-Point Flexure via Fiber Optic Sensing.

Pultruded carbon fiber-reinforced composites are attractive to the wind energy industry due to the rapid production of highly aligned unidirectional composites with enhanced fiber volume fractions and increased specific strength and stiffness. However, high volume carbon fiber manufacturing remains cost-prohibitive. This study investigates the feasibility of a pultruded low-cost textile carbon fiber-reinforced epoxy composite as a promising material in spar cap production was undertaken based on mechanical response to four-point flexure loading.

Examining the association between fentanyl use and perceived adequacy of methadone dose: A retrospective cohort study.

Background: People exposed to fentanyl may report that the dose of methadone in the commonly accepted therapeutic range feels too low. We examined self-reported methadone dose adequacy.

Methods: We conducted a retrospective cohort study of individuals prescribed methadone at a dose of at least 60mg daily using data from three community-recruited prospective cohort studies of people who use drugs in Vancouver, Canada from December 2016 through March 2020.

Household water security is a mediator of household food security in a nationally representative sample of Mexico.

Objective: Explore the relationship between water insecurity and food security and their covariates in Mexican households.

Design: A cross-sectional study with nationally representative data from the National Health and Nutrition Survey-Continuous 2021 (in Spanish, ENSANUT-Continua 2021), collected data from 12,619 households.

Setting: Water insecurity was measured using the Household Water Insecurity Experiences (HWISE) Scale in Spanish and adapted to the Mexican context.

Sex differences in mitochondrial free-carnitine levels in subjects at-risk and with Alzheimer's disease in two independent study cohorts.

A major challenge in the development of more effective therapeutic strategies for Alzheimer's disease (AD) is the identification of molecular mechanisms linked to specific pathophysiological features of the disease. Importantly AD has a two-fold higher incidence in women than men and a protracted prodromal phase characterized by amnestic mild-cognitive impairment (aMCI) suggesting that biological processes occurring early can initiate vulnerability to AD. Here, we used a sample of 125 subjects from two independent study cohorts to determine the levels in plasma (the most accessible specimen) of two essential mitochondrial markers acetyl-L-carnitine (LAC) and its derivative free-carnitine motivated by a mechanistic model in rodents in which targeting mitochondrial metabolism of LAC leads to the amelioration of cognitive function and boosts epigenetic mechanisms of gene expression.
