Differential bone calcium retention with the use of oral versus vaginal hormonal contraception: A randomized trial using calcium-41 radiotracer.

Objectives: This study aimed to assess if hormonal contraception administered orally (combined oral contraceptive pill, COC) or vaginally (contraceptive vaginal ring) differentially affected bone calcium retention in young females.

Study Design: Reproductive aged females (18-35 years) not using hormonal contraception were dosed with 50 nCi Ca as CaCl in 10 mL of sterile saline (0.9%).

Network analysis of U.S. non-fatal opioid-involved overdose journeys, 2018-2023.

We present a nation-wide network analysis of non-fatal opioid-involved overdose journeys in the United States. Leveraging a unique proprietary dataset of Emergency Medical Services incidents, we construct a journey-to-overdose geospatial network capturing nearly half a million opioid-involved overdose events spanning 2018-2023. We analyze the structure and sociological profiles of the nodes, which are counties or their equivalents, characterize the distribution of overdose journey lengths, and investigate changes in the journey network between 2018 and 2023.

Comparative evaluation of swabbing sites for Omicron variant detection in PCR testing.

Purpose: The Omicron variant of SARS-CoV-2 raised concerns about the best sampling sites for PCR testing, with early indications suggesting throat swab samples were better than nasal swab samples. Our study evaluated the sensitivity of detecting SARS-CoV-2 across different swabbing sites.

Methods: Participants undergoing testing at NHS Test and Trace sites in England provided self-collected samples using nose only, throat only, and combined nose and throat swabs, which were analysed by realtime PCR.

How can HIV self-testing facilitate increased access to HIV testing among multiply marginalised populations? Perspectives from GBMSM and trans women in England and Wales.

Background: HIV self-testing (HIVST) may facilitate marginalised populations' uptake of HIV testing, but whether the extent of marginalisation challenges individual uptake of HIVST remains under-researched. We aim to explore the perspectives of multiply marginalised cis-gender gay, bisexual and other men who have sex with men (GBMSM) and trans women on whether HIVST might increase their uptake of HIV testing.

Methods: We reanalysed qualitative interview data from SELPHI (the UK's largest HIVST randomised trial) collected between 2017 and 2020 from marginalised populations, defined as people self-identifying as non-heterosexual, transgender, non-White ethnicity and/or with low educational attainment.

Living and Researching the COVID-19 Pandemic: Autoethnographic Reflections from a Co-Research Team of Older People and Academics.

This article describes and reflects upon the work of a co-research team on the Healthy Ageing in Scotland (HAGIS) 'COVID-19 Impact and Recovery' study (January 2021 to November 2022). The co-research team (seven older adults and three academics) was constituted near the start of this project; the team contributed to the development of recruitment materials and research tools and undertook qualitative research and analysis with older adults living across Scotland. This article provides a collaborative autoethnography about the activities undertaken by the team, the impact of the co-research process on the individuals involved, and the research findings and reflects the realities of co-research during the COVID-19 pandemic.
