METHODS: From 2010 to 2014, men with HIV (N = 212) and opioid dependence before incarceration were enrolled in MMT within 6 months of release from Malaysia's largest prison and followed for 12-months post-release. As a prospective trial, allocation to MMT was at random and later by preference design (predictive nonetheless). MMT dosing was individually targeted to minimally achieve 80 mg/day. Time-to-event analyses were conducted to model linkage to MMT after release.
FINDINGS: Of the 212 participants allocated to MMT, 98 (46 %) were prescribed higher dosages (≥80 mg/day) before release. Linkage to MMT after release occurred in 77 (36 %) participants and significantly higher for those prescribed higher dosages (46% vs 28 %; p = 0.011). Factors associated with higher MMT dosages were being married, on antiretroviral therapy, longer incarceration periods, having higher levels of depression, and methadone preference compared to randomization. After controlling for other variables, being prescribed higher methadone dosage (aHR: 2.53, 95 %CI: 1.42-4.49) was the only independent predictor of linkage to methadone after release.
INTERPRETATION: Higher doses of methadone prescribed before release increased the likelihood of linkage to MMT after release. Methadone dosing should be introduced into international guidelines for treatment of opioid use disorder in prisons and further post-release benefits should be explored.

METHODS: This retrospective analysis included all new HIV diagnosis from 2016 to 2019 at the University of Malaya Medical Centre, Malaysia. Trends of HIV diagnosis was assessed using join point regression analysis, and characteristics between the older and younger adults were compared using χ 2 test or Mann-Whitney U test. Kaplan-Meier analysis and log-rank test were used to compare the survival probability in both age groups.
RESULTS: From a total of 594 new HIV diagnosis between 2016 and 2019, 11.5% (N = 68) were among older adults with an annual percent increase of 5.50%. Older adults were more likely ethnic Indians ( P < 0.001), acquired HIV through heterosexual contact ( P = 0.001), had late presentation to care ( P = 0.003), and multimorbidity ( P < 0.001). Immunological responses after 12 months on antiretroviral therapy were comparable in both the groups. Older adults had a higher probability of death compared with younger adults (adjusted hazard ratio 1.81, 95% confidence interval: 1.02 to 3.23, P = 0.043) after adjusting for sex, mode of HIV transmission, late presentation to care, antiretroviral therapy initiation, and multimorbidity.
CONCLUSION: Older adults diagnosed with HIV were associated with late care presentation and increased mortality. There is an urgent need to enhance uptake of HIV testing and linkage to care among older individuals in our setting.
