BACKGROUND Injecting drug users (IDUs) are a major and most important risk factor for rising hepatitis C virus (HCV) prevalence in Iran. OBJECTIVES The objective of this study was to determine the effectiveness of methadone maintenance treatment (MMT) in prevention of HCV infection transmission among IDUs. PATIENTS AND METHODS A mathematical modeling has been used to estimate number of HCV ...

Despite the efficacy of methadone maintenance treatment (MMT), opioid dependence still involves severe impairment of functioning and low quality of life. This study examines the influence of the psychiatric comorbidity of MMT patients on their quality of life. A total of 193 middle-aged patients in long-term MMT were assessed for current and lifetime Axis I psychiatric disorders, substance use ...

OBJECTIVE To examine the effect of methadone maintenance treatment (MMT) on mortality in people injecting opioids who receive antiretroviral therapy (ART) for the treatment of human immunodeficiency virus (HIV) infection in China. METHODS The study involved a nationwide cohort of 23 813 HIV-positive (HIV+) people injecting opioids who received ART between 31 December 2002 and 31 December 2011...

BACKGROUND Methadone maintenance treatment (MMT) improves patients' ability to access HIV-related services and reduces needle sharing and other risky HIV-related behaviors. However, patients may continue to engage in risky sexual practices. In this study, we evaluate sexual behaviors of MMT patients in a mountainous province in Northern Vietnam. METHODS We explored the health status, MMT and ...

The effect of the pristine sodium montmorillonite (Na-MMT) on the styrene emulsion polymerizations with different concentrations of SDS ([SDS]) was investigated. At constant [SDS], the polymerization rate is faster for the run with 1 wt.% Na-MMT compared to the counterpart without Na-MMT. Micelle nucleation predominates in the polymerizations with [SDS] = 13 mM. On the other hand, the contribut...

BACKGROUND Hepatitis C virus (HCV) is the most common viral infection among injecting drug users worldwide. We aimed to assess HCV antibody prevalence and associated risk factors among clients in the Chinese national methadone maintenance treatment (MMT) program. METHODS Data from 296,209 clients who enrolled in the national MMT program between March 2004 and December 2012 were analyzed to as...

PROBLEM China's National Methadone Maintenance Treatment Programme (MMT) has expanded from eight clinics serving approximately 1000 clients to 738 clinics that have served more than 340 000 clients cumulatively in only 8 years. This has created an enormous demand for trained providers. APPROACH Human resource development and capacity building efforts have been conducted in China's National MM...

OBJECTIVE There is a significant interindividual variability in treatment outcomes in methadone maintenance treatment (MMT) for opioid use disorder (OUD). This prospective cohort study examines the impact of comorbid psychiatric disorders on continued illicit opioid use in patients receiving MMT for OUD. METHODS Data were collected from 935 patients receiving MMT in outpatient clinics between...

MMT (Methadone maintenance treatment) is an effective way to treat opioid dependence. In Portugal, an MMT program has been available in pharmacies since January 1998, when a formal agreement was signed by the IDT, I.P. (Institute on Drugs and Drug Addiction), the PPS (Portuguese Pharmaceutical Society), and the ANF (National Association of Pharmacies). In January 2004, the INFARMED (National Au...
