Seroprevalence of Rubella among Women of Reproductive Age in Iran: A Prisma-Based Systematic Review and Meta-Analysis.

OBJECTIVE: Rubella is a highly contagious viral disease with a significant teratogenic effect. Various results have been published about the seroprevalence of rubella in Iran. A PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses)-systematic review and meta-analysis were conducted to assess the immunity against rubella in Iranian women. METHODS: Eleven English and Persian electronic databases including PubMed, ScienceDirect, Scopus, Web of Science, Google Scholar, Embase, Scientific Information Database, Iran doc, Iran Medex, Magiran, and Medlib were searched using the keywords: Epidemiology, Prevalence, Rubella, Women, Childbearing age, Reproductive age, and Iran. A mathematician (NS) reviewed all steps for accuracy. RESULTS: Out of 1,520 articles, 25 well-conducted studies with a total amount of 10,145 women were reviewed. The pooled prevalence rate of anti-rubella IgG was 84% (95% CI: 83%-86%). The highest prevalence rate of IgG was in Zahedan, Rasht, and Arak (each 100%), while the lowest prevalence was in Jahrom (54%). Subgroup analysis showed that from 1989 through 2012, the IgG prevalence rate increased from 78% (95% CI: 73-83%) to 99% (95% CI: 98 100%). CONCLUSIONS: Although the vaccination program seems working in Iran, some peripheral regions may be a target to improve health care policies.

Seroprevalence of Cytomegalovirus among Women of Reproductive Age in Iran: A Systematic Review and Meta-Analysis.

BACKGROUND: Human cytomegalovirus (CMV) able to cause infection for an entire lifetime. This systematic review and meta-analysis was conducted to determine seroprevalence of CMV among women of reproductive age in Iran. METHODS: English and Persian databases such as Web of Science (WOS), PubMed, Scopus, Cochrane Library, SID, Iran doc, Iran Medex, Magiran, and Medlib were searched (from 2008 to 2017) accurately using the keywords: Cytomegalovirus, Pregnant women or Pregnancy, Epidemiology, Prevalence and Iran. RESULTS: Results of 15 studies with total samples of 5253 persons from 2008 to 2017 were combined and meta-analyzed. The pooled prevalence rate of IgG among women was estimated 90% (95% CI: 87-93%). The highest prevalence rate of IgG was in Tehran, Rasht, Mashhad and Yasoj, all 100% (95% CI: 100-100%), and the lowest prevalence was in Jahrom 0.62% (95% CI: 53-71%). The overall prevalence rate of IgM among women was estimated at 0.06% (95% CI: 0.03-0.13%). The highest prevalence rate of IgM was in Kerman 0.34% (95% CI: 0.29-0.39%) and Mashhad 0.25% (95% CI: 0.2-0.31%), and the lowest prevalence was in Yasoj 0% (95% CI: 0.00%-0.00%). CONCLUSION: The prevalence of immunity in Iran, is satisfactory. Nevertheless, to maintain and increase the level of immunity across the country, it is necessary to routinely screen the women of reproductive ages across the country.

Medicinal Plants in the Prevention and Treatment of Colon Cancer.

The standard treatment for cancer is generally based on using cytotoxic drugs, radiotherapy, chemotherapy, and surgery. However, the use of traditional treatments has received attention in recent years. The aim of the present work was to provide an overview of medicinal plants effective on colon cancer with special emphasis on bioactive components and underlying mechanisms of action. Various literature databases, including Web of Science, PubMed, and Scopus, were used and English language articles were considered. Based on literature search, 172 experimental studies and 71 clinical cases on 190 plants were included. The results indicate that grape, soybean, green tea, garlic, olive, and pomegranate are the most effective plants against colon cancer. In these studies, fruits, seeds, leaves, and plant roots were used for in vitro and in vivo models. Various anticolon cancer mechanisms of these medicinal plants include induction of superoxide dismutase, reduction of DNA oxidation, induction of apoptosis by inducing a cell cycle arrest in S phase, reducing the expression of PI3K, P-Akt protein, and MMP as well; reduction of antiapoptotic Bcl-2 and Bcl-xL proteins, and decrease of proliferating cell nuclear antigen (PCNA), cyclin A, cyclin D1, cyclin B1 and cyclin E. Plant compounds also increase both the expression of the cell cycle inhibitors p53, p21, and p27, and the BAD, Bax, caspase 3, caspase 7, caspase 8, and caspase 9 proteins levels. In fact, purification of herbal compounds and demonstration of their efficacy in appropriate in vivo models, as well as clinical studies, may lead to alternative and effective ways of controlling and treating colon cancer.

An update and systematic review on the treatment of primary dysmenorrhea.

OBJECTIVES: Primary dysmenorrhea is a painful uterine contraction caused by endometrial laceration. Drug therapies and complementary medicine have been used to treat dysmenorrhea. The aim of this study was to investigate and offer an updated perspective on the treatments for dysmenorrhea. METHODS: The present study was conducted in accordance with the PRISMA checklist for systematic reviews and meta-analyses. The required information was collected based on searches for the following keywords: treatment, primary dysmenorrhea, medicinal plants, chemical drugs, and herbs. Searches were performed on databases Pubmed, Web of Sciences, Scopus, Iran medex, and SID by March 2018 to find literature in the English and Persian languages on this subject without a time limit. RESULTS: This review included 17 papers, 10 of which on complementary medicine, three on drug therapies, and four on acupuncture and acupressure. The largest and smallest samples had 303 and 24 patients, respectively. Length of treatment ranged from one to six months and the measures most commonly used in the studies were the visual analogue scale and clinical efficacy. Reported complications included gastrointestinal events, nausea, vomiting, diarrhea, abdominal pain, and liver and kidney disorders. CONCLUSION: Medicinal plants, drugs, and acupressure seem to suppress pain by reducing the level of prostaglandins, mediating nitric oxide, increasing beta-endorphin levels, blocking the calcium channel, and enhancing circulatory flow through the uterine pathway. Further trials are required to confirm the benefits of the procedures described and ensure the absence of complications.

Prevalence of Human Immunodeficiency Virus in Iranian Blood Donors: A Systematic Review and Meta-Analysis.

BACKGROUND: The probability of HIV transmission through contaminated blood and blood products is eye catching. 5%-10% of blood products are contaminated with HIV. Therefore, it is essential to provide safe blood supply to prevent transmission of infectious diseases. Current systematic review and meta-analysis was conducted to evaluate the weighted prevalence of HIV in Iranian blood donors. METHODS: This study was reported according to PRISMA checklist for systematic reviews and meta- analysis. Required data were collected by using key words such as "HIV", "blood donation" OR "blood donors", "epidemiology" OR "prevalence", "blood transfusion" and "Iran", in international databases including PubMed, Scopus, Web of Science, Cochrane, Embase and national databases including Magiran, IranMedex and Scientific Information Databank. Papers were searched until December 2017. Cochran's Q test and I2 index were used to assess the heterogeneity among studies. RESULTS: A total of 49 studies including 5403170 donors entered this meta-analysis. According to analysis, the prevalence of HIV-positive patients among Iran blood donors was estimated 7.9/100000 (95% CI: 0.000052-0.000121%). The highest prevalence was related to the central region of Iran (11.3/100,000 [95% CI:0.000063-0.0002%]) and Kermanshah province (49.2/100000 [95% CI:0.000273-0.000888%]) and the lowest prevalence was related to the eastern region (1/100000 [95% CI:0.000001-0.000072%]) and Khorasan Razavi province (0.9/100000 [95% CI:0.000001-0.000139%]. CONCLUSION: The overall HIV prevalence in Iranian blood donors is low and satisfying. However, the high prevalence in some regions and provinces should be reviewed more meticulously.

The effect of celery (Apium graveolens L.) on fertility: A systematic review.

Background Fertility and infertility problems are among the complex issues in medicine. The use of herbal products in the treatment of fertility has been considered as an alternative to synthetic drugs. Celery containing known compounds can have an impact on the fertility rate. The aim of this study was to do a systematic review on conducted studies in conjunction with the celery and reproduction. Methods Required papers were searched from databases like Science direct, PubMed, Scopus, and Springer. Keywords used in this study were "Apium graveolens L.", "fertility", "reproductive system", "sperm", "testis", "delivery", "sexual hormone", "LH", "FSH", "testosterone", "semen", "male", and "female". Out of 238 collected articles (published in the period 1995 to 2015), 222 were excluded due to non-relevance and lack of access to the original article. Results The notable points were the different results seen by different researchers during different treatment periods or at different doses. Of the 16 studies reviewed in this study, 13 studies have mentioned the positive effect of celery on fertility, while three studies reported the inhibitory effects of this plant. Conclusions Celery can have protective effects against substances such as sodium valproate, propylene glycol, and diethyl phthalate causing damages to the testicular structure and spermatogenesis. In this regard, the doses used and the treatment time while using the plant must be accurately investigated. Since there are compounds such as apigenin, the celery can induce inhibitory effects on fertility in case of chronic use or high concentration.
