The effectiveness of mobile-based ecological momentary motivational enhancement therapy in reducing craving and severity of cannabis use disorder: Study protocol for a randomized controlled trial.

Objective: This study aims to investigate the effectiveness of Ecological Momentary Motivational Enhancement Therapy (EM-MET) in reducing craving and severity of Cannabis Use Disorder (CUD) among young adults.

Methods: This multicenter, single-blinded randomized controlled trial (RCT) will be conducted over a period of 11 weeks. Eighty patients with CUD will be randomly assigned to two equal-sized parallel groups, either the Motivational Enhancement Therapy (MET) group or the EM-MET group.

The potential protective effect of melatonin and N-acetylcysteine alone and in combination on opioid-induced testicular dysfunction and degeneration in rat.

Methadone (Met) is the most common treatment for opioid addiction. Although Met is effective for treatment of opioid dependence, sexual dysfunctions and infertility have been reported as a major problem in patients under Met treatment. The present study aimed to evaluate the effect of melatonin and N-acetylcysteine (N) on morphine and Met-induced oxidative stress, apoptosis, suppression of blood sexual hormones, impairment in sperm parameters, and sexual dysfunction.

Lifetime and past-month substance use and injection among street-based female sex workers in Iran.

Background: Street-based female sex workers (FSWs) are highly at risk of HIV and other harms associated with sex work. We assessed the prevalence of non-injection and injection drug use and their associated factors among street-based FSWs in Iran.

Methods: We recruited 898 FSWs from 414 venues across 19 major cities in Iran between October 2016 and March 2017.

Correlation Between Protamine-2 and miRNA-122 in Sperm from Heroin-addicted Men: A Case-Control Study.

Purpose: Recreational use of illicit drugs is one of the main factors affecting male fertility. However, the mechanisms of heroin smoke-associated damage to mature spermatozoa are still completely unknown. The aim of this study was to concomitantly examine the levels of protamine-2 gene and protein concentrations, the amount of miRNA-122 in seminal plasma and semen analysis findings in heroin-addicted men.

Evaluation of Enkephalin-Degrading Enzymes in Sperm from Heroin-Addicted Men.

Background: The aim of this study was to investigate two enkephalin-degrading enzymes, aminopeptidase N (APN/ CD13) and endopeptidase (NEP/CD10), gene and protein expression levels in sperm samples of fertile and heroinaddicted men, and the correlation between their expressions and semen quality.

Materials And Methods: In this case-controlled study, semen was collected from 24 normozoospermic healthy (as a control group) and 24 heroin-addicted men donors (as case or addiction group). Sperm cells isolated by Cook Medical gradient (40-80%) and followed up by swim-up techniques were used for real-time quantitative polymerase chain reaction (qPCR) and flow cytometry techniques to assess and genes and proteins subsequently.

Profile of drug users in the residential treatment centers of Tehran, Iran.

The current study aimed at determining the pattern of drug dependence and its related factors in mid-term residential treatment centers (MTRCs). The current cross-sectional study was conducted on all drug dependent people residing in MTRCs of Tehran, Iran, who were voluntarily seeking treatment from April to August, 2018. Required data were collected through face-to-face interviews.

The Effect of Heroin Addiction on Human Sperm Parameters, Histone-to-Protamine Transition, and Serum Sexual Hormones Levels.

Purpose: To investigate the effects of heroin on sperm parameters, histone-to-protamine transition ratios in mature sperm, and serum reproductive hormone levels in active heroin users.

Materials And Methods: Semen and blood samples were collected from 25 men who used only heroin for at least 12 months and the same number healthy men who did not use any drugs and did not suffer from infertility problems. Computer-based analysis, Aniline blue staining, and hormonal assessment were performed to provide valuable new information on the relationship between addiction and semen profile and serum reproductive hor-mone levels.

Needle and syringe sharing among Iranian drug injectors.

Objective: The role of needle and syringe sharing behavior of injection drug users (IDUs) in spreading of blood-borne infections - specially HIV/AIDS - is well known. However, very little is known in this regard from Iran. The aim of our study was to determine the prevalence and associates of needle and syringe sharing among Iranian IDUs.
