The rising threat of illicit amphetamine-type stimulant use among methadone maintenance treatment patients in East Coast Malaysia: a retrospective observational study.

In recent years, amphetamine-type-stimulants (ATS) have been extensively misused in South-East Asia, inducing major problems among methadone-maintenance-treatment (MMT) patients. We examine ATS-misuse prevalence and its determinants among MMT patients in East-Coast-Malaysia. A retrospective-observational study was conducted on government-subsidized medication for opioid-use-disorder (MOUD) treatment clinics involving 292 MMT-patients (98% males) who were selected using a multilevel-proportional-stratified random sampling technique.

Socioecological Challenges of Polio Supplementary Immunization Activities (SIAs) in the Asia-Pacific Region: A Systematic Review.

Background: Polio supplementary immunization activities (SIAs) are one of the polio eradication pillars in the Global Polio Eradication Initiative (GPEI) that increased the immunization coverage and made progress towards polio eradication. However, socioecological challenges faced during SIAs contribute to suboptimal campaign quality. The aim of this review is to identify the reported challenges during polio supplementary immunization activities (SIAs) and associated improvement strategies based on the socioecological model (SEM).
