Status of Total Antioxidant Capacity and Malondialdehyde Level in Methamphetamine Addicts: A Cross Sectional Study

Background: Methamphetamine (MA) is an illegal amphetamine-like which stimulate the central nervous system. In recent years, MA has been widely abused worldwide. Previous studies have suggested that oxidative stress (OS) plays an important role in MA-induced toxicity. From this view, antioxidant therapy could be considered as a potential drug therapy in MA abusers. Therefore, the objective of this study was to evaluate OS status in MA abusers.Methods: This was a cross-sectional study conducted on 21 MA abusers who referred to Iranian National Center for Addiction Studies and Congress 60 Humane Revivification Society, and 15 healthy males as a control group. The demographic data and peripheral blood sampling was obtained from both groups. The serum malondialdehyde (MDA) level as a marker of plasma lipid peroxidation and total antioxidant capacity (TAC) of plasma were analyzed.Results: Significant decrease in plasma TAC in case group was observed (101.85±12.5 vs. 130.7±16.12 mmol/L). No significant increase in MDA serum level was detected in case group in comparison with control (27.35±2.6 vs. 26.67±2.22 µmol/L, respectively). Neither the serum MDA levels nor the plasma TAC were significantly correlated with the duration and amount of MA abuse.Conclusion: It seems that, MA abuse is associated with prooxidant-antioxidant imbalance, which suggests evaluation the role of antioxidants administration for the prevention and treatment of MA-induced toxicity

Setting research priorities to achieve long-term health targets in Iran

Background: In 2015, it was estimated that the burden of disease in Iran comprised of 19 million disability-adjusted life years (DALYs), 74% of which were due to non-communicable diseases (NCDs). The observed leading causes of death were cardiovascular diseases (41.9%), neoplasms (14.9%), and road traffic injuries (7.4%). Even so, the health research investment in Iran continues to remain limited. This study aims to identify national health research priorities in Iran for the next five years to assist the efficient use of resources towards achieving the long-term health targets. Methods: Adapting the Child Health and Nutrition Research Initiative (CHNRI) method, this study engaged 48 prominent Iranian academic leaders in the areas related to Iran's long-term health targets, a group of research funders and policy makers, and 68 stakeholders from the wider society. 128 proposed research questions were scored independently using a set of five criteria: feasibility, impact on health, impact on economy, capacity building, and equity. Findings: The top-10 priorities were focused on the research questions relating to: health insurance system reforms to improve equity; integration of NCDs prevention strategy into primary health care; cost-effective population-level interventions for NCDs and road traffic injury prevention; tailoring medical qualifications; epidemiological assessment of NCDs by geographic areas; equality in the distribution of health resources and services; current and future common health problems in Iran's elderly and strategies to reduce their economic burden; the status of antibiotic resistance in Iran and strategies to promote rational use of antibiotics; the health impacts of water crisis; and research to replace the physician-centered health system with a team-based one. Conclusions: These findings highlight consensus amongst various prominent Iranian researchers and stakeholders over the research priorities that require investment to generate information and knowledge relevant to the national health targets and policies. The exercise should assist in addressing the knowledge gaps to support both the National General Health Policies by 2025 and the health targets of the United Nations' Sustainable Development Goals by 2030
