Assessing whether providing regular, free HIV self-testing kits reduces the time to HIV diagnosis: an internet-based, randomised controlled trial in men who have sex with men.

Background: The risk of onwards HIV transmission is strongly influenced by the interval between HIV infection and its diagnosis. The SELPHI trial examined whether this interval could be reduced by offering free HIV self-testing kits to men-who-have-sex with-men (MSM).

Setting: Internet-based RCT of MSM aged ≥16 years, resident in England/Wales, recruited via sexual and social networking sites.

Randomized Comparison of Magnetic Resonance Imaging Versus Transurethral Resection for Staging New Bladder Cancers: Results From the Prospective BladderPath Trial.

Purpose: Transurethral resection of bladder tumor (TURBT) is the initial staging procedure for new bladder cancers (BCs). For muscle-invasive bladder cancers (MIBCs), TURBT may delay definitive treatment. We investigated whether definitive treatment can be expedited for MIBC using flexible cystoscopic biopsy and multiparametric magnetic resonance imaging (mpMRI) for initial staging.

Impact of Frailty on Antihypertensive Treatment in Older Adults.

Background: The association between systolic blood pressure and all-cause mortality differs between frail and nonfrail individuals, highlighting uncertainties about the effectiveness of antihypertensive treatments in frail populations.

Methods: Using data from the SHEP trial (Systolic Hypertension in the Elderly Program), a baseline frailty index (FI), including 55 variables, was constructed. Fine-Gray subdistribution hazard models and Cox proportional hazards regression models were used to explore the association between baseline FI and the risks of stroke, cardiovascular disease, and all-cause death, as well as to examine whether the impact of antihypertensive treatment on these outcomes was modified by baseline FI.

University Students Implement a Nutrition and Cooking Education Curriculum With Fidelity.

Objective: To assess the ability of trained university students to implement Cooking Matters for Kids, a hands-on nutrition and cooking education curriculum for third through fifth-grade children.

Methods: Process evaluation data were collected from 6 Cooking Matters for Kids courses led by university students in the fall of 2019 and spring of 2020 at 6 afterschool programs in Orange County, North Carolina. Trained research assistants observed lessons and reported whether key intervention components were implemented as planned, the level of participant engagement, what worked well, and what could be improved on.

Serological insights from SARS-CoV-2 heterologous prime and boost responses in Thailand.

During the COVID-19 pandemic, heterologous vaccination strategies were employed to alleviate the strain on vaccine supplies. The Thailand Ministry of Health adopted these strategies using vector, inactivated, and mRNA vaccines. However, this approach has introduced challenges for SARS-CoV-2 sero-epidemiology studies.
