Background: The multi-day Boston Remote Assessment of Neurocognitive Health (BRANCH) is a remote, web-based assessment designed to capture the earliest cognitive changes in the preclinical stage of Alzheimer's disease (AD). It has been validated in unimpaired older adults, but as individuals progress on the AD continuum, assessments need to remain feasible and valid at different clinical stages. The focus of this study was to assess feasibility and validity of multi-day BRANCH in participants with and without cognitive impairment.

Methods: The progression of synapsis was interpreted according to the dynamics of the cohesin subunit SMC3 axes. DNA double-strand breaks were revealed by RAD51 immunolabeling, while transcriptional activity was determined by the presence of RNA polymerase II phosphorylated at serine 2 (pRNApol II) immunolabeling.
Introduction: This narrative review aims to identify and explore the social determinants that prevent people living with HIV (PWH) from accessing specialized cancer centers in the United States and compare to patient experiences in other countries.
Methods: The review includes randomized controlled trials, cohort studies, case-control studies, qualitative studies, case series, and non-peer reviewed articles. The risk of bias was assessed using standardized tools, and data were synthesized narratively due to the heterogeneity of study designs and outcomes.
Background: Contingency management (CM), an incentive-based intervention to encourage target behaviors, effectively promotes medication adherence. However, efforts to extend CM to HIV pre-exposure prophylaxis (PrEP) have been lacking. As part of a randomized clinical trial to promote HIV Prevention among people who inject drugs (PWID), we examined the readiness of staff in community-based organizations serving PWID to implement CM for PrEP uptake and adherence in this population.

- The study examines the link between oral microbiome diversity and mortality rates from all causes, cardiovascular disease (CVD), and non-CVD, highlighting gaps in knowledge regarding sex and racial/ethnic variations.
- Using data from the National Health and Nutrition Examination Survey (NHANES), researchers analyzed oral rinse samples from 8,199 adults and tracked mortality over about 9 years to assess the impact of microbial diversity on health outcomes.
- Findings indicate that higher oral microbiome diversity is associated with lower mortality rates across groups, particularly among Mexican Americans and Non-Hispanic Whites, but potential mediators like obesity or diabetes did not influence this relationship.
