HIV Disclosure Anxiety:A Systematic Review and Theoretical Synthesis

HIV disclosure can help people living with HIV to access social support, enhance antiretroviral adherence, facilitate engagement in care and reduce unprotected sex. Given interpersonal risks associated with HIV disclosure, however, anxiety about sharing one’s status is common. To investigate anxiety about HIV disclosure in HIV-positive populations, we conducted a systematic review of qualitative and quantitative studies, with 119 studies included. The review demonstrated that perceived interpersonal risks are associated with HIV disclosure and outlined evidence of associations with anxiety, fear and worry. We present a new cognitive model of HIV disclosure anxiety adapted from clinical theories of health and social anxiety, consistent with evidence from the review. The model attempts to explain the development and maintenance of anxiety in individuals whose functioning is most affected by concerns about sharing their status. Implications for helping people living with HIV struggling with significant levels of anxiety about HIV disclosure are discussed.

Are take-home naloxone programmes effective? Systematic review utilizing application of the Bradford Hill criteria.

Fatal outcome of opioid overdose, once detected, is preventable through timely administration of the antidote naloxone. Take-home naloxone provision directly to opioid users for emergency use has been implemented recently in more than 15 countries worldwide, albeit mainly as pilot schemes and without formal evaluation. This systematic review assesses the effectiveness of take-home naloxone, with two specific aims: (1) to study the impact of take-home naloxone distribution on overdose-related mortality; and (2) to assess the safety of take-home naloxone in terms of adverse events. Conclusions: Take-home naloxone programmes are found to reduce overdose mortality among programme participants and in the community and have a low rate of adverse events

Nanocomposite Thermosetting Materials for HVDC Applications

This paper reviews the objectives of a new project that is engaging the challenge to develop and scale the processing of nanocomposite thermosetting electrical insulation materials for HVDC power transmission applications. We discuss some of the work being carried out by the project and potential deployment in HVDC schemes
