Investigating the trend and severity of withdrawal symptoms in Methamphetamine users amongst homeless addicts

Background: Determining the trend and severity of withdrawal symptoms is considered as the first stage of addiction treatment. Objectives: Therefore, The purpose of this study was to investigate the trend and severity of withdrawal symptoms in methamphetamine (meth) addicts. Patients and Methods: This cross-sectional study was conducted on all the clients admitted to quit methamphetamine abuse in a residential treatment center for homeless addicts in Alborz province. According to the average daily intake, the clients were divided into two groups: mild and severe. To collect the data for this study; methamphetamine withdrawal symptoms assessment scale, Beck Depression Inventory (BDI) and a demographic information questionnaire were used. The analysis of variance (ANOVA) was done for repeated measures through the SPSS software version 16 and at a significance level of 0.05. Results: The findings showed that methamphetamine withdrawal symptoms including anxiety, abuse craving, and fatigue in the first 24 hours and the first, the second, and the third weeks as well as the symptoms of depression within three weeks after the withdrawal began to decline significantly (P < 0.0001). Following the analysis of variance (ANOVA) for repeated data and taking addiction severity index into account, it was observed that the difference between the two groups of mild and severe addicts was significant in terms of the trend and severity of methamphetamine withdrawal symptoms (P < 0.0001). Conclusions: The hardest stage to quit methamphetamine addiction was the first 24 hours after withdrawal with a downward trend; however, abuse craving especially in severe addicted group persisted even after the third week of withdrawal which could be a risk factor for recurrence and re-abuse. Thus, it was suggested that therapists were required to pay more attention to this issue in the treatment of this group of addicted individuals. © 2018, International Journal of High Risk Behaviors and Addiction

Molecular assay on Crimean Congo Hemorrhagic Fever virus in ticks (Ixodidae) collected from Kermanshah Province, Western Iran

Background: Crimean-Congo Hemorrhagic Fever (CCHF) is a feverous and hemorrhagic disease endemic in some parts of Iran and caused by an arbovirus related to Bunyaviridae family and Nairovirusgenus. The main virus reservoir in the nature is ticks, however small vertebrates and a wide range of domestic and wild animals are regarded as reservoir hosts. This study was conducted to determine the infection rate of CCHF virus in hard ticks of Sarpole- Zahab County, Kermanshah province, west of Iran. Methods: From total number of 851 collected ticks from 8 villages, 131 ticks were selected randomlyand investigated for detection of CCHF virus using RT-PCR. Results: The virus was found in 3.8 of the tested ticks. Hyalommaanatolicum, H.asiaticum and Rhipicephalus sanguineus species were found to have viral infection, with the highest infection rate (11.11) in Rh. sanguineus. Conclusion: These findings provide epidemiological evidence for planning control strategies of the disease in the study area

Molecular identification of some Haemaphysalis species (Acari: Ixodidae) using mitochondrial and nuclear evidences in parts of Iran

Haemaphysalis is the second largest ixodid tick genus. We decided to identify the Iranian Haemaphysalis species with the analysis of mitochondrial (COI & 16S rRNA) and nuclear (ITS2) gene sequences. Finally, 21 PCR products were sequenced, successfully. Phylogenetic trees were analyzed using BEAST software and Bayesian Inference method. Ha. sulcata and Ha. punctata were well differentiated using the 16S rRNA, COI and ITS2 genes. According to 16S rRNA and COI phylogenetic trees Ha. inermis is situated as an ancestral clade. © Systematic & Applied Acarology Society

Ticks circulate Anaplasma, Ehrlichia, Babesia and Theileria parasites in North of Iran

Ticks serve as important vectors of some pathogens of medical importance all over the world and identification of their rate of infection plays an important role for further control of diseases. In the current study, we investigated on ticks collected from north of Iran where raising and caring livestock are the main task of the people in order to find evidences of infection of Babesia, Theileria, Anaplasma and Ehrlichia microbial agents. Totally, 609 hard tick species from two genera Hyalomma and Rhipicephalus including; Hy. scupense, Hy. dromedarii, Hy. rufipes, Hy. marginatum, Hy. asiaticum, Hy. anatolicum, R. bursa, R. sanguineus and R. turanicus were identified. Molecular analysis revealed the presence of Anaplasma, Ehrlichia, Babesia and Theileria microorganism agents in all collected tick species except Hy. asiaticum and R. turanicus. To the best of our knowledge, this is the first report on identification of B. occultans in Hyalomma anatolicum and B. ovis in Hyalomma sp in Iran. © 2017 Elsevier B.V
