BackgroundAsymptomatic bacteriuria (ASB) is defined as the presence of bacteria in urine without having signs and symptoms. The aim of this meta-analysis was to estimate the overall prevalence of asymptomatic bacteriuria among Iranian pregnant women.MethodsMajor national and international databases were searched up to November 2015, including Scientific Information Database, MagIran, Web of Science, Medline, Scopus, Science Direct and Ovid. The checklist of the STROBE statement was used for evaluating the quality of reporting. The extracted data were analyzed and the results were reported using a random-effects model with 95% confidence interval (CI).ResultsFrom 3709 obtained studies, 20 included in the meta-analysis, which involved 15108 pregnant women. The overall prevalence of ASB was 0.13 (95% CI: 0.09, 0.17). The prevalence of ASB in the northern and southern regions of Iran was 0.13 (95% CI: 0.09, 0.18) and 0.11 (95% CI: 0.05, 0.16), respectively.ConclusionPrevalence of ASB among Iranian pregnant women is considerable. Due to the complications of ASB for pregnant women and their children, preventative planning and control of ASB among pregnant women in Iran is necessary.

Background: Ovarian cancer (OC) has high incidence and mortality rates among the reproductive system cancers. This study investigated the relationship between the agestandardized incidence rate (ASIR) and age-standardized mortality rate (ASMR) of OC and Human Development Index (HDI) in European countries in 2012.

INTRODUCTIONFarming is one of the most important components of the economy in most countries. It exerts major effects on both public health and food safety. The agricultural workforce, consisting of over 1.1 billion individuals, is the largest workforce in the world. Moreover, the health of farmworkers has an important role in food provision [1]. Farming is known as a high-risk job in both developed and developing countries [1,2]. In addition to exposure to physical, chemical, and biological risk factors, work-related injuries and accidents can also threaten the health of farmworkers [3][4][5].Agriculture plays an important economic role in the lives of people in many countries, including Iran [6]. In 2015, more than 18.0% of employees (approximately 4 million people) in Iran worked in the farming sector [7]. According to previous studies, occupational hazards such as musculoskeletal disorders [8] and injuries [9], pesticide poisoning, skin cancer, and infectious diseases threaten the health of Iranian farmworkers [10][11][12]. Unfortunately, there is no comprehensive occupational health monitoring system for farming-related diseases and injuries in Iran. Based on the available health indices, in 2010, only 32.0% of Iranian farmworkers were registered with the health system. Of these, 18.7% were covered by health care services and regular screening tests [13].However, despite the magnitude of agricultural areas and the agricultural workforce in Iran, limited epidemiologic research has Farming is one of the most important components of most economies. No comprehensive picture exists of the health status of Iranian farmers and the work-related hazards that affect them. We aimed to determine the gaps in the current knowledge regarding the occupational health of Iranian farmworkers. Electronic databases including Medline, Web of Science, Scopus, and Embase, as well as national databases including the Scientific Information Database, MagIran, and Barakat Knowledge System, were searched for articles published through March 2017. All epidemiologic studies regarding the occupational health of farmworkers in Iran were reviewed, regardless of their design, language, time of publication, and location. Of the 86 retrieved articles, 39 studies were ultimately analyzed. Most studies were conducted in Fars, Kerman, and Mazandaran provinces. According to the results of this review, chemical, physical, and biological hazards, along with work-related injuries, may be the main factors threatening the health of farmworkers. The unsafe use of pesticides was related to male infertility, eye and digestive complications, pesticide poisoning, pesticide absorption, hematological changes, non-Hodgkin lymphoma, and multiple myeloma. Chemical hazards (e.g., the unsafe use of pesticides), physical hazards, injuries, and biological hazards (e.g., work-related infectious diseases) threaten the health of Iranian farmworkers. Moreover, farmworkers lack adequate knowledge about the occupational hazards they face and the relevant risk factors.

OBJECTIVESAccess to dental healthcare services is a major determinant of dental health in communities. This meta-analysis was conducted to estimate the global prevalence of dental needs and of unmet dental needs in adolescents.METHODSPubMed, Web of Science, and Scopus were searched in June 2018. The summary measures included the prevalence of met and unmet dental needs. A meta-analysis was performed using the inverse variance method to obtain pooled summary measures. Out of 41,661 retrieved articles, 57 were ultimately included.RESULTSThe pooled prevalence of orthodontic treatment needs was 46.0% (95% confidence interval [CI], 38.0 to 53.0), that of general treatment needs was 59.0% (95% CI, 42.0 to 75.0), that of periodontal treatment needs was 71.0% (95% CI, 46.0 to 96.0), and that of malocclusion treatment needs was 39.0% (95% CI, 28.0 to 50.0). The pooled prevalence of unmet dental needs was 34.0% (95% CI, 27.0 to 40.0).CONCLUSIONSThe highest and lowest prevalence of unmet dental needs were found in Southeast Asia and Europe, respectively. The prevalence of dental needs was higher in the countries of the Americas and Europe than in other World Health Organization (WHO) regions. The prevalence of unmet dental needs was higher in Southeast Asia and Africa than in other WHO regions.

Background:Cardiac and respiratory arrest is reversible through immediate cardiopulmonary resuscitation (CPR). However, survival after CPR is very low for various reasons. This systematic review study was conducted to assess the effect of palliative care on quality of life and survival after CPR.Methods:In the present meta-analysis and systematic review study, two researchers independently searched Google Scholar and MagIran, MedLib, IranMedex, SID, and PubMed for articles published during 1994–2016 and containing a number of relevant keywords and their Medical Subject Headings (MeSH) combinations. A total of 156 articles were initially extracted.Results:The success of initial resuscitation was reported to be much higher than the success of secondary resuscitation (survival until discharge). Moreover, the early detection of cardiac arrest, a high-quality CPR, immediate defibrillation, and effective postresuscitation care improved short- and long-term outcomes in these patients and significantly affected their quality of life after CPR. Most survivors of CPR can have a reasonable quality of life if they are given proper follow-up and persistent treatment.Conclusions:Concerns about the low quality of life after CPR are therefore not a worthy reason to end the efforts taken for the victims of cardiac arrest. More comprehensive education programs and facilities are required for the resuscitation of patients and the provision of post-CPR intensive care.
