Prevalence of visually significant cataract and cataract surgical coverage in Indigenous and non-Indigenous Australians: a systematic review and meta-analysis.

Aims: Compare the prevalence of age-related cataract and the cataract surgical coverage rate between Indigenous and non-Indigenous Australians and explore differences in these estimates across location and time.

Methods: The Joanna Briggs Institute guidance for systematic reviews of prevalence studies was followed. A systematic search of Medline, Embase, Web of Science and grey literature from database inception to June 2022 was performed.

Use of period- or fertility-tracking technologies pre- and post-Dobbs.

Objective: This study aimed to evaluate whether use of period- or fertility-tracking technologies decreased from pre- to post-Dobbs, and to identify user characteristics and changes in reasons for use.

Study Design: We used data from the Surveys of Women, population-based surveys on reproductive health among self-identified women aged 18-44 years, conducted in five states. We compared prevalence of use of period- or fertility-tracking technologies and reasons for use pre-Dobbs (2018-2019 in Iowa and Ohio; 2019-2020 in Arizona, New Jersey, and Wisconsin) and post-Dobbs (2022-2023 in all five states), overall and stratified by state.

Machine learning derived retinal pigment score from ophthalmic imaging shows ethnicity is not biology.

Few metrics exist to describe phenotypic diversity within ophthalmic imaging datasets, with researchers often using ethnicity as a surrogate marker for biological variability. We derived a continuous, measured metric, the retinal pigment score (RPS), that quantifies the degree of pigmentation from a colour fundus photograph of the eye. RPS was validated using two large epidemiological studies with demographic and genetic data (UK Biobank and EPIC-Norfolk Study) and reproduced in a Tanzanian, an Australian, and a Chinese dataset.

International Expert Consensus on Relevant Health and Functioning Concepts to Assess in Users of Tobacco and Nicotine Products: Delphi Study.

Background: A Delphi study was conducted to reach a consensus among international clinical and health care experts on the most important health and functioning self-reported concepts when evaluating a switch from smoking cigarettes to using smoke-free tobacco and/or nicotine products (sf-TNPs).

Objective: The aim of this research was to identify concepts considered important to measure when assessing the health and functioning status of users of tobacco and/or nicotine products.

Methods: Experts (n=105), including health care professionals, researchers, and policy makers, from 26 countries with professional experience and knowledge of sf-TNPs completed a 3-round, adapted Delphi panel.
