A mechanistic connection between aging and development is largely unexplored. Through profiling age-related chromatin and transcriptional changes across 22 murine cell types, analyzed alongside previous mouse and human organismal maturation datasets, we uncovered a transcription factor binding site (TFBS) signature common to both processes. Early-life candidate cis-regulatory elements (cCREs), progressively losing accessibility during maturation and aging, are enriched for cell-type identity TFBSs.

Introduction: This study explored the behaviours of people living with HIV in Singapore and Hong Kong in terms of achieving and maintaining their physical and psychological wellbeing in relation to HIV, to identify the challenges and support needed in HIV care.

Methods: This qualitative study involved 90-minute interviews among Singapore and Hong Kong people living with HIV aged ≥18 years to explore health-related quality of life perceptions and gaps in patient empowerment in HIV care during February-May 2022. The COM-B (C: Capability; O: Opportunity; M: Motivation; B: Behaviour) framework was used during data analysis to identify behaviour facilitators and barriers for people living with HIV to achieve and maintain their wellbeing.

Background: Counseling support for HIV self-testing (HIVST) users is essential to ensure support and linkage to care among men who have sex with men (MSM). An HIVST service with web-based real-time instruction, pretest, and posttest counseling provided by trained administrators (HIVST-OIC) was developed by previous projects. Although the HIVST-OIC was highly effective in increasing HIVST uptake and the proportion of HIVST users receiving counseling along with testing, it required intensive resources to implement and sustain.

The COVID-19 pandemic created disruptions in HIV testing service utilization among men who have sex with men (MSM). The present study was to evaluate the effectiveness of an online health promotion program implemented by a community-based organization (CBO) in increasing the uptake of any type of HIV testing and home-based HIV self-testing (HIVST) over a six-month follow-up period. Participants of an observational prospective cohort study conducted during the same period served as the comparison group.
