Background: Prostate cancer is a global health concern. In Iran, its epidemiology is not precisely recognized. We aimed to evaluate incidence of prostate cancer among Iranian populations. Methods: In this systematic review, we searched the databases PubMed, Web of Sciences, Scopus and Google Scholar for English studies and the databases Magiran, Scientific information Database, IranMedex and IranDoc for Persian studies, using related keywords. The cross sectional articles published from inception to 31 December 2018 were included. Meta-analysis was conducted on the collected data with STATA software using random effects model. Results: Out of 763 articles initially obtained, 9 articles were finally included after applying the predefined exclusion criteria. Analysis of 9 studies on the incidence of prostate cancer showed a crude rate of 7.1 per 100000 population (95% confidence interval [CI]: 5.6-8.6). Also, the pooled age-standardized incidence rate was 8.7 per 100000 (95% CI: 6.7-10.4). Studies performed in the period 2004-2012 had significantly a higher pooled estimate of the crude incidence rate (9.2 per 100000 [95% CI: 7.9-10.4]) compared with those conducted in the period 1996-2003 (4.5 per 100000 [95% CI: 2.8-6.2]). This trend was also observed based on the age-standardized incidence rate (11 per 100000 [95% CI: 9.4-12.5] versus 6.3 per 100000[95% CI: 4-8.5]).Conclusion: Despite low rate of prostate cancer occurrence in Iran, it is recommended that preventive measures be taken against this disease by health policymakers. Also, more epidemiological studies are needed to better find out the pattern of prostate cancer among Iranian populations.

Abstract Background Hepatitis E virus (HEV) is a major cause of acute hepatitis in humans worldwide and have high burden in the resource-limited countries. Better knowledge of the epidemiology of hepatitis in animals in Africa can help to understand the epidemiology among humans. The objective of this study was to summarize the prevalence of HEV infection and distribution of HEV genotypes among animals in Africa. Methods In this systematic review and meta-analysis, we comprehensively searched PubMed, EMBASE, African Journals Online, and Africa Index Medicus from January 1st, 2000 to March 22th, 2020 without any language restriction. We considered cross-sectional studies of HEV infection in animals in Africa. Study selection, data extraction, and methodological quality of included studies were done independently by two investigators. Prevalence data were pooled using the random-effects meta-analysis. This review was registered in PROSPERO, CRD42018087684. Results Twenty-five studies (13 species and 6983 animals) were included. The prevalence (antibodies or ribonucleic acid [RNA]) of HEV infection in animals varied widely depending on biological markers of HEV infection measured: 23.4% (95% confidence interval; 12.0–37.2) for anti-HEV immunoglobulins G, 13.1% (3.1–28.3) for anti-HEV immunoglobulins M, and 1.8% (0.2–4.3) for RNA; with substantial heterogeneity. In subgroup analysis, the immunoglobulins G seroprevalence was higher among pigs 37.8% (13.9–65.4). The following HEV genotypes were reported in animals: Rat-HEV genotype 1 (rats and horses), HEV-3 (pigs), HEV-7 (dromedaries), and Bat hepeviruses (bats). Conclusions We found a high prevalence of HEV infection in animals in Africa and HEV genotypes close to that of humans. Some animals in Africa could be the reservoir of HEV, highlighting the need of molecular epidemiological studies for investigating zoonotic transmission.

Neighbourhood Socioeconomic Status

ObjectiveLow neighbourhood socioeconomic status (NSES) has been linked to a higher risk of overweight/obesity, irrespective of the individual’s own socioeconomic status. No meta-analysis study has been done on the association. Thus, this study was done to synthesise the existing evidence on the association of NSES with overweight, obesity and body mass index (BMI).DesignSystematic review and meta-analysis.Data sourcesPubMed, Embase, Scopus, Cochrane Library, Web of Sciences and Google Scholar databases were searched for articles published until 25 September 2019.Eligibility criteriaEpidemiological studies, both longitudinal and cross-sectional ones, which examined the link of NSES to overweight, obesity or BMI, were included.Data extraction and synthesisData extraction was done by two reviewers, working independently. The methodological quality of included studies was assessed using the Newcastle-Ottawa Scale for the observational studies. The summary estimates of the relationships of NSES with overweight, obesity and BMI statuses were calculated with random-effects meta-analysis models. Heterogeneity was assessed by Cochran’s Q and I2 statistics. Subgroup analyses were done by age categories, continents, study designs and NSES measures. Publication bias was assessed by visual inspection of funnel plots and Egger’s regression test.ResultA total of 21 observational studies, covering 1 244 438 individuals, were included in this meta-analysis. Low NSES, compared with high NSES, was found to be associated with a 31% higher odds of overweight (pooled OR 1.31, 95% CI 1.16 to 1.47, p<0.001), a 45% higher odds of obesity (pooled OR 1.45, 95% CI 1.21 to 1.74, p<0.001) and a 1.09 kg/m2 increase in mean BMI (pooled beta=1.09, 95% CI 0.67 to 1.50, p<0.001).ConclusionNSES disparity might be contributing to the burden of overweight/obesity. Further studies are warranted, including whether addressing NSES disparity could reduce the risk of overweight/obesity.PROSPERO registration numberCRD42017063889

IntroductionChronic inflammatory diseases such as eczema (also known as atopic dermatitis) have been inconsistently linked to cardiovascular disease and stroke in both mechanistic and epidemiological studies. There is a need to review the existing epidemiological data examining the association between eczema and major cardiovascular outcomes, including angina, myocardial infarction, coronary revascularisation, heart failure, cardiac arrhythmias, stroke and cardiovascular death, in order to improve our understanding of the comorbidities of eczema.Methods and analysisWe will systematically review population-based studies, including cohort, case–control and cross-sectional studies, reporting on the association between eczema and cardiovascular outcomes. We will search Medline, Embase and Global Health, from their date of inception to April 2017, using a comprehensive search strategy formulated with the help of a librarian. Two reviewers will independently screen titles and abstracts in duplicate, followed by independent data extraction and quality assessment. We will group studies by the cardiovascular outcome under study and synthesise them narratively. If sufficient numbers of homogeneous studies are returned, we will perform meta-analyses to obtain pooled effect estimates. Preferred Reporting Items for Systematic Review and Meta-Analysis will be used to inform the reporting of this study.Trial registration numberCRD42017060359.

Abstract introduction: HIV and HCV is a health concern in the word. Therefore, this systematic review and meta-analysis protocol study is aimed to estimate the incidence of HIV and HCV among People who inject drugs (PWID) by applying mathematical modeling. The primary purpose of this systematic review is to identify and review existing studies of HIV and HCV incidence in people who inject drugs, that use mathematical modeling. Methods and analysis: Studies including cohort, cross-sectional, case–control studies which were conducted to estimate incidence of HIV and HCV based on mathematical or evaluated effectiveness of mathematical models will be considered to enroll the review; a comprehensive search with Cochrane approach would be applied to identify relevant studies in electronic databases in the period of 2000 to 2019. This protocol was prepared according to the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P) and we will search PubMed, EMBASE, Opengrey, WOS, SCOPUS, and Cochrane Library with no restriction of language. Study selection and data extraction will be performed by two independent reviewers. Assessment of risk of bias will be implemented using three quality test tools including Newcastle Ottawa Scale and ROBIS scale for cross-sectional studies and quantitative studies quality test tool for observational and interventional studies for other study Publication bias will be assessed by funnel plots, Begg’s and Egger’s tests. Heterogeneity will be evaluated using the I2 statistic and the χ2 test. In addition, subgroup analyses will be conducted for population and the secondary outcomes.

Menopause can cause mental, physical, vasomotor, and sexual symptoms and problems, which negatively affect the quality of life (QOL). The aim of this study was to systematically evaluate QOL among Iranian postmenopausal women. This systematic review was conducted on cross-sectional studies that were published between 2000 and 2018. An online search to find studies published in English or Persian was conducted in the databases of Web of Science, PubMed, ScienceDirect, Scopus, Google Scholar, Scientific Information Database, Magiran, and IranMedex. Search key terms were “quality of life”, “menopause”, and “Iran”. Fourteen studies were eligible for this study. The Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) checklist was used for quality appraisal. The mean and standard deviation of QOL and its domains were extracted from the selected studies. Study data were analyzed using the Review Manager (v. 5.0) and the STATA (v. 12.0) software. The mean of total QOL among 3413 postmenopausal women was 57.89±12.8 (in the possible range of 0–174). The means of its vasomotor, psychosocial, physical, and sexual domains were 7.86±2.14, 19.43±2.05, 40.58±3.33, and 6.71±1.77, respectively. The QOL among Iranian postmenopausal women is nearly higher than the moderate level. The lowest and the highest levels of QOL are related to the physical and sexual domains, respectively. Health authorities need to develop educational interventions to promote postmenopausal women’s QOL, particularly in the physical domain. [GMJ.2020;9:e1649]

Background. Asthma is an important reason for hospitalization in children aged under five years. Information about the current status of asthma in Iranian children can help the Iranian health sector plan carefully and prevent asthma incidence by educating the families. The present systematic review and meta-analysis is aimed at estimating asthma prevalence in Iranian children and adolescents. Method. Data were found using keywords such as prevalence, epidemiology, asthma, adolescent, children, pediatrics, Iran in Web of Science, Scopus, PubMed, Cochrane, and Embase databases. Three national databases, including Magiran, Barakat Pharmed Co (Iran medex), and Scientific Information Databank (SID) were searched until 1 October 2020. Cross-sectional and original studies were included in the study, and then, quality assessment was done using the National Institutes of Health’s Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies. A pooled estimated prevalence of asthma was calculated using Der Simonian-Laird random model. Egger’s test was used to evaluate publication bias. The data were analyzed using the STATA software version 16. Results. 30 studies were selected and investigated. The prevalence of asthma in children and adolescents was 6% and 8%, and the prevalence in boys and girls was 9% and 8%, respectively. Among the asthma symptoms, wheezing had the most prevalence (17% in children and 19% in adolescents) and sleep disturbance had the lowest prevalence (6% in children and 6% in adolescents). Conclusion. The prevalence of asthma in Iranian children and adolescents is lower than in the world. Existing strategies should be pursued followed. Also, guidelines for asthma control and prevention should be considered in the future.

Objective: Acute poisoning is a major health problem and one of the most common causes of emergency visits worldwide. Since most poisoning subjects present with a decreased level of consciousness and due to unreliable disease history, recognizing the etiological cause of the poisoning represents a critical part in arranging the treatment strategy. This study aimed at examining the prevalence of etiological causes of poisoning in Iran in a systematic review and meta-analysis. Method: This systematic review and meta-analysis investigated the cross-sectional studies published from 1990 to 2020, reporting specific poisoning agents among acute poisoning cases in Iran. Persian and English articles on this subject were collected by searching the Scientific Information Database (SID), ScienceDirect, PubMed, Medlib, IranMedex, Scopus, Magiran, and Google Scholar databases. The heterogeneity of the studies was investigated using the I2 index and the probability of bias in the publication was assessed by the Begg and Mazumdar test with a significance level of 0.1. Data analysis was performed by Comprehensive Meta-analysis software version 3 (Biostat, Englewood, NJ, USA). Results: In our review, 19 studies appraising 143,251 cases of poisoning were included. The ranking of the OR of each agent was done; Opium poisoning was the most prevalent poisoning case followed by benzodiazepine, acetaminophen, antipsychotic medications, organophosphates, aluminum phosphide, amphetamine, pesticide, tricyclic antidepressant (TCA), alcohol, chemicals, carbon monoxide (CO), nonsteroidal anti-inflammatory drugs (NSAIDs), and selective serotonin reuptake inhibitors (SSRIs). Conclusion: While proper judgment on the cause of poisoning and selection of suitable treatment manners could be followed by a very good prognosis in patients with acute poisoning; this demands an epidemiological perception of the prevalence of the etiological poisoning agents. Our study ranked the most likely agents leading to the poisoning, to be at the top of the list of differential diagnoses of physicians.

Background: Childhood cancer (ChC) is very rare and occurs between birth and 14 years of age. There are several reports about ChC incidence from various regions of Iran, but with conflicting results.  The present study aimed to do a systematic review to estimate the accurate incidence rate of ChC among Iranian people. Materials and Methods: This systematic review was performed based on the preferred reporting items for systematic reviews and meta-analyses (PRISMA) checklist in 2018. A literature search was conducted using international databases (Medline/PubMed, Scopus, ISI/Web of Knowledge, and Google Scholar) for English papers, and national databases (Scientific Information Database, MagIran, IranMedex, and IranDoc) for Persian papers which estimated the incidence rate of ChC in any geographical location in  Iran. The incidence rate of ChC was calculated using random-effect model. Results: Out of 157 papers in the primary searches, 12 studies were included by advanced screening and refinement. The crude incidence rate (CIR) of ChC in 0-14 years was 16.8 per 100,000 (95% CI: 9.04-24.56) for boys and 16.56 per 100,000 (95% CI: 10.51-22.62) for girls. Conclusion: The incidence of ChC in Iran is higher compared to other parts of the world. Considering this issue, holding some interventional programs on tackling potential risk factors, including air pollution, in different regions of Iran is suggested.

Pulpitis is a common occurrence in clinical practice. To date, few systematic reviews have evaluated the epidemiology of various treatment modalities in endodontics. The objective of this study is to analyse the epidemiology of endodontics as presented in various publications. Methodology :Clinical, experimental and review reports were searched in PubMed, Cochrane databases and Google Scholar for scientific literature in November 2019, using the search phrase “endodontic epidemiology” Results : Of the eight potentially relevant publications, six of which were randomised controlled trials, with no statistically significant results, one was a systematic review and the other was a cross-sectional study. Conclusion: Endodontic epidemiological studies are being conducted, however the results are not statistically significant. This does not necessarily mean that the results of such studies obtained cannot be applied clinically.

Abstract. Backgrounds: Central obesity, as a pivotal component of metabolic syndrome is associated with numerous co-morbidities. Dietary factors influence central obesity by increased inflammatory status. However, recent studies didn’t evaluate the association between central obesity and dietary inflammation index (DII®) that give score to dietary factors according to their inflammatory potential. In the current systematic review and meta-analysis, we summarized the studies that investigated the association between DII® with central obesity indices in the general populations. Methods: In a systematic search from PubMed, SCOPUS, Web of Sciences and Cochrane electronic databases, we collected relevant studies written in English and published until 30 October 2019. The population of included studies were apparently healthy subjects or individuals with obesity or obesity-related diseases. Observational studies that evaluated the association between DII® and indices of central obesity including WC or WHR were included. Results: Totally thirty-two studies were included; thirty studies were cross-sectional and two were cohort studies with 103071 participants. Meta-analysis of observational studies showed that higher DII® scores were associated with 1.81 cm increase in WC (Pooled weighted mean difference (WMD) = 1.813; CI: 0.785–2.841; p = 0.001). Also, a non-significant increase in the odds of having higher WC (OR = 1.162; CI: 0.95–1.43; p = 0.154) in the highest DII category was also observed. In subgroup analysis, the continent, dietary assessment tool and gender were the heterogeneity sources. Conclusion: The findings proposed that adherence to diets with high DII® scores was associated with increased WC. Further studies with interventional designs are necessary to elucidate the causality inference between DII® and central obesity indices.
