Long-term control of viral replication relies on the efficient differentiation of memory T cells into effector T cells during secondary immune responses. Recent findings have identified T cell precursors for both memory and exhausted T cells, suggesting the existence of progenitor-like effector T cells. These cells can persist without antigenic challenge but expand and acquire effector functions upon recall immune responses.

Introduction: WHO's Integrated Care for Older People (ICOPE) proposes we measure the functional construct of intrinsic capacity (IC) to monitor and identify individuals with age-associated vulnerabilities. Assessments of IC may be useful to address the evolving, non-HV care needs of ageing people with HIV (PWH). However, to date, its utility within the context of HIV has not been assessed.

Prevalence and incidence of HIV among people aged 50 years and older continue to rise worldwide, generating increasing awareness among care providers, scientists, and the HIV community about the importance of brain health in older adults with HIV. Many age-related factors that adversely affect brain health can occur earlier and more often among people with HIV, including epigenetic ageing, chronic medical conditions (eg, cardiovascular disease), and age-related syndromes (eg, frailty). Extensive dialogue between HIV community leaders, health-care providers, and scientists has led to the development of a multidimensional response strategy to protect and enhance brain health in people ageing with HIV that spans across public health, clinical spaces, and research spaces.

Background: Mental health and substance use disorders are common among people living with HIV and are associated with high-risk sexual behaviors, such as unprotected sex and multiple sexual partners, but Asia-Pacific data are limited.

Methods: Adult PLHIV in care at five Asia-Pacific HIV clinics were enrolled at routine clinic visits between July 2019 and June 2020. Depression, substance use, sexual practice and socio-demographic data were collected using PHQ-9, ASSIST, and a study-specific questionnaire.

Article Synopsis
  • - This clinical trial compared the safety and effectiveness of an inhaled COVID-19 vaccine (Ad5-nCoV-IH) against an intramuscular vaccine (BNT-IM) in 540 vaccinated adults in Malaysia from September 2022 to May 2023.
  • - While Ad5-nCoV-IH exhibited lower immunogenicity (with a GMC ratio of 0.22) compared to BNT-IM, it resulted in fewer adverse drug reactions (39.26% vs. 64.68%) and no serious side effects were documented.
  • - Both vaccines demonstrated similar efficacy against COVID-19 variants, but the study concluded that Ad5-nCoV-IH did not meet the non
