The relationship between emotional intelligence, spiritual intelligence, and student achievement: a systematic review and meta-analysis.

INTRODUCTION: Emotional and spiritual intelligence are crucial factors in enhancing individuals' knowledge and academic achievement. This study aims to examine the correlation between spiritual intelligence, emotional intelligence, and student achievement through a systematic review and meta-analysis. MATERIALS AND METHODS: A search was conducted in the PubMed, Scopus, Web of Science, SID, and Google Scholar databases from 2007 to December 2022. The effect sizes (EF) included the mean and standard deviation of emotional intelligence, spiritual intelligence, and student achievement and correlation coefficients among spiritual intelligence, emotional intelligence, and student achievement. Random effects models were used to pool the results, and the Q test and I2 index were employed to assess heterogeneity. Correlation coefficients were transformed into standard data (Z) using log transformation. RESULTS: The overall mean score of educational achievement in university and school students was 15.91 (95% CI: 15.26-16.78). The mean scores of spiritual and emotional intelligence were 138.27 (95% CI: 129.19-147.35) and 128.94 (95% CI: 117.08-140.80), respectively. The correlation coefficients between spiritual intelligence, emotional intelligence, and student achievement were r = 0.36 (95% CI: 0.18-0.51) and r = 0.50 (95% CI: 0.28-0.67), respectively. CONCLUSIONS: Emotional and spiritual intelligence are independent predictive factors in educational achievement for university and school students. Therefore, improvements in emotional and spiritual intelligence can promote students' academic achievement.

Vaginal bleeding in pregnancy and adverse clinical outcomes: a systematic review and meta-analysis.

Background: Vaginal bleeding during pregnancy has been recognised as a significant risk factor for adverse pregnancy outcomes. This study aimed to investigate the association between vaginal bleeding during the first trimester of pregnancy and clinical adverse effects using a systematic review and meta-analysis.Methods: Databases of Scopus, Web of Science, PubMed (including Medline), Cochrane Library and Science Direct were searched until June of 2023. Data analysis using statistical test fixed- and random-effects models in the meta-analysis, Cochran and meta-regression. The quality of the eligible studies was assessed by using the Newcastle-Ottawa Scale checklist (NOS).Results: A total of 46 relevant studies, with a sample size of 1,554,141 were entered into the meta-analysis. Vaginal bleeding during the first trimester of pregnancy increases the risk of preterm birth (OR: 1.8, CI 95%: 1.6-2.0), low birth weight (LBW; OR: 2.0, CI 95%: 1.5-2.6), premature rupture of membranes (PROMs; OR: 2.3, CI 95%: 1.8-3.0), abortion (OR: 4.3, CI 95%: 2.0-9.0), stillbirth (OR: 2.5, CI 95%: 1.2-5.0), placental abruption (OR: 2.2, CI 95%: 1.4-3.3) and placenta previa (OR: 1.9, CI 95%: 1.5-2.4).Conclusions: Vaginal bleeding in the first trimester of pregnancy is associated with preterm birth, LBW, PROMs, miscarriage, stillbirth, placental abruption and placenta previa. Therefore, physicians or midwives need to be aware of the possibility of these consequences and manage them when they occur.

Vaginal bleeding in the first trimester of pregnancy increases the relative risk of preterm birth, low birth weight, premature rupture of membranes, abortion, stillbirth, placental abruption and placenta previa.

The effect of nutritional factors on urolithiasis: A case-control study.

Urolithiasis, a prevalent chronic kidney disease affecting all age groups, can be influenced by nutritional factors. The incidence of urolithiasis in Asian countries ranges from 1% to 19.1%, attributed to geographical and lifestyle differences. In Iran, several risk factors, including ethnicity, dietary habits, gender, and age, are associated with urolithiasis. This study aimed to assess the impact of nutritional factors on kidney and urinary tract stone formation. This case-control study enrolled 127 newly diagnosed urolithiasis patients, and 127 matched healthy participants between February to May 2017. Exclusion criteria included diabetes and acute or chronic renal failure. Data were collected using the Food Frequency Questionnaire (FFQ) and analyzed using chi-square and logistic regression tests. Water (95% CI: 0.09-0.89, OR=0.28), natural juices (95% CI: 0.10-0.65, OR=0.53), mineral water (95% CI: 0.05-0.64, OR=0.18), legumes (95% CI: 0.00-0.38, OR=0.032), butter, cream, or peppermint (95% CI: 0.09-0.95, OR=0.30), and ice cream (95% CI: 0.07-0.54, OR=0.203) had a significant protective effect against kidney and urinary tract stone formation. Conversely, tea consumption (95% CI: 1.15-7.99, OR=4.70), beverages (95% CI: 4.45-23.32, OR=23.32), coffee (95% CI: 1.63-11.78, OR=4.39), bread (95% CI: 1.1-10.59, OR=3.37), meat (95% CI: 1.01-8.01, OR=2.85), liver (95% CI: 3.37-488.90, OR=40.58), fish (95% CI: 2.89-216.39, OR=25.03), and various canned foods (95% CI: 1.34-10.25, OR=3.70) were significantly associated with kidney and urinary tract stone risk. These findings showed that the risk of urinary stones formation had a significant relationship with dietary habits. Therefore, the correct dietary pattern and sufficient fluid consumption may play an important role in preventing urinary stones.

Rate and Causes of Suicide in Ilam: A Report of the Suicide Registry.

Objective: Suicide is one of the most important health problems in the world. Financial, academic, social, and environmental difficulties along with genetic, physical, and mental disorders affect suicide attempts. This study aimed to find risk factors for completed suicide in Ilam province according to the suicide registry in Ilam province. Method : This was a prospective study and was performed based on suicide case registration data, pre-determined checklist data, and death registration data in Ilam province from March 2019 to September 2020. Logistic regression models and the Chi-square test were used to determine the relationship between completed suicide and its risk factors. Results: Among 1,410 attempted suicides, 66 (4.7 %) were executed. Rate of completed suicides was higher in men (6.5%) compared to women (4.5%), (p = 0.005), age groups over 65 years (P < 0.001), retirees and farmers (P = 0.009), illiterate people (P < 0.001), villagers (P = 0.02), people motivated due to physical problems (P = 0.016), suicide by physical methods (P < 0.001) and self-immolation (P < 0.001). Logistic regression showed that incidence of completed suicide was significantly higher in the age group over 65 years, illiterate people, people using physical methods, villagers, and men. Multivariate logistic regression also showed that men and individuals using physical methods of suicide were significantly more successful in suicide. Conclusion: Men, the elderly, illiterates, villagers, and people who used physical suicide methods were in high-risk groups. Despite lower prevalence of suicide, a higher rate of completed suicide was demonstrated. To decrease completed suicide rates, we must pay attention to these groups.

Association between Influenza and COVID-19 Viruses and the Risk of Atherosclerosis: Meta-Analysis Study and Systematic Review.

There is a lot of evidence to suggest that patients infected with the COVID-19 and influenza viruses are at risk of atherosclerosis. Additionally, there are heterogeneous studies on the risk of arthrosclerosis in patients infected with the influenza and COVID-19 viruses. We conducted a case−control and cross-sectional study and examined the association between the risk of atherosclerosis, and influenza virus (IV-A and IV-B) and COVID-19 infections in this study. We searched for keywords such as influenza virus, COVID-19 and atherosclerosis in English and Persian in well-known databases such as PubMed, SID, Magiran and Google Scholar. In this study, we analyzed the information using a meta-analysis, the random effect model, the I2 index and STAT (version 11.2). The results from the analysis of ten studies on influenza virus and nine studies on COVID-19 reviewed individually (totaling 6428 samples for influenza virus infections and 10,785 samples for COVID-19 infections) demonstrated a risk of arthrosclerosis in patients with influenza and COVID-19 infections, with an OR (odds ratio) = 0.45 ((95% CI): 0.25 to 0.64) and an OR (odds ratio) = 1.04 ((95% CI): 0.82 to 1.26), respectively. The present study provides new insights into the risk of atherosclerosis in patients infected with the COVID-19 and influenza viruses. Therefore, it seems necessary to consider different strategies for managing and eradicating viral infections among individuals.

Chlamydia pneumoniae and Mycoplasma pneumoniae as Two Emerging Risk Factors in Atherosclerosis: Meta-Analysis Study and Systematic Review.

BACKGROUND: Previous studies suggested an association between Chlamydia pneumoniae and Mycoplasma pneumonia with atherosclerosis, separately. Until now, according to inconsistent information, the relationship between C.pneumoniae and M.pneumoniae with atherosclerosis is controversial. OBJECTIVE: The aim of this study is to investigate the association between C.pneumoniae and M.pneumoniae as two separate risk factors with atherosclerosis through systematic review and metaanalysis study. METHODS: We searched databases, such as Pubmed, SID, Magiran, Google scholar and Iranmedex, using the following keywords in English and Persian language: C. pneumoniae, M. pneumoniae, and atherosclerosis. Data were analyzed with meta-analysis and a random effect model. Also, in this study, heterogeneity of articles was estimated by using the I2 index. Finally, the data were analyzed with STAT (version 11.2). RESULTS: Among thirty-eight articles for C. pneumoniae and five articles for M. pneumoniae individually reviewed that included 2980 samples for M. pneumoniae and 23298 samples for C. pneumoniae, the result demonstrated that the association between M. pneumoniae and C. pneumoniae with atherosclerosis is significant with OR (odds ratio) = 1.58 (95% Confidence Interval (CI): 1.00 to 2.50), OR (odds ratio) = 2.25 (95% Confidence Interval (CI): 1.91 to 2.64), respectively. CONCLUSION: This systematic review study provides strong evidence for the role of persistent bacterial infections, such as M. pneumoniae and C. pneumoniae, in potential atherosclerosis. Thus, a novel way should be employed for the complete management of bacterial infection.

Prevalence of Cutaneous Leishmaniasis in Iran (2000-2016): A Systematic Review and Meta-analysis Study.

BACKGROUND AND OBJECTIVE: Cutaneous leishmaniasis (CL) is the most common form of leishmaniasis affecting humans. The purpose of this study was to determine the prevalence and epidemiological features of CL in Iran by a systematic review and meta-analysis. METHODS: The literature search was performed in the SID, Magiran, IranDoc, PubMed, Scopus, Medlib, as well as the Google Scholar search engine databases to find studies on the prevalence of CL. The reference lists of the found articles were also reviewed to obtain additional relevant articles. Studies that were related to treatment and reservoirs of CL were excluded. Forty-four studies were selected for the final analysis. RESULTS: Meta-analysis with a random-effects model showed that the prevalence of leishmaniasis in Iran was 77 per 100,000 population. Overall, 60% of the patients were men. Most cases of CL occurred in autumn, and the majority of the patients had one lesion, mostly on hands. The most common age group was 20-30 years. CONCLUSION: In conclusion, CL is an endemic disease in Iran, and its prevalence is largely affected by geographical locations and regional customs. Appropriate preventing measures should be considered to decrease the incidence of CL in Iran.

Prediction of Suicide Attempts Using the Box-Jenkins Model.

Objective: Suicide is a preventable social harm in the field of health. The present study aimed to design a prediction model for suicide incidence based on Box-Jenkins model in Ilam province. Method : Using a retrospective method all completed and attempted suicide data were collected during 1993-2013. Then, using the autoregressive integrated moving average (ARIMA) model, the time series analysis of the Box-Jenkins model was conducted to predict suicide status in the coming years (2014-2015). Results: According to the actual results obtained from the suicide data in 2014, a total of 1078 suicides were recorded and compared to the predicted results, according to the fitted model of the time series, which showed the selected model predicted 931 suicide cases, showing 86% accuracy of prediction. The series' prediction indicated 931 suicides in 2014 with a negative growth rate of 25.3% compared to 2013 and 969 suicide cases in 2015 with a positive growth rate of 3.93% compared to 2014. Conclusion: The results of this study showed the designed model provides a high diagnostic value to predict suicide rates. These types of models can help to predict suicide in future and plan to control and prevent suicide attempts.

Association between plasma leptin/adiponectin ratios with the extent and severity of coronary artery disease.

BACKGROUND: Leptin can have a direct effect on endothelial and vascular smooth muscle cells and high level of leptin is involved in the pathogenesis of atherosclerosis. This study aimed to determine the relationship between leptin/adiponectin (L/A) ratio and the extent and severity of coronary artery disease (CAD). METHODS: This case-control study was conducted in an educational hospital in Ilam, Iran from June 2014 to September 2015. Totally 300 participants including 150 patients with CAD (case group) and 150 healthy individuals (control group) were selected and their plasma leptin, adiponectin and leptin/adiponectin ratio was measured. The extent and severity of coronary artery disease were assayed based on the number of involved vessels and Gensini score (GS) and the relation between scores and L/A findings were compared between cases and controls. RESULTS: Totally, 300 participants including 150 (42.7% male), mean age 59.5 ± 11.4 years as cases and 150 (50.7% male), mean age 59.8 ± 10.7 as controls were analyzed. Plasma level of leptin and L/A ratio were higher in cases compared to controls, but level of adiponectin was significantly lower in CAD patients than the control group. More number of involved coronary vessels was significantly correlated to higher level of plasma leptin, L/A ratio and lower level of adiponectin among case group. Moreover, adiponectin was negatively and leptin or L/A ratio were positively correlated with number of involved vessels. 7.3% of cases had only one involved vessel, 42.7% had two involved vessels, and 50% of total patients had involved vessels and the mean ± SD of GS in the case group was 23.6 ± 6.9. CONCLUSIONS: Plasma levels of leptin, and adiponectin can indicate the extent of coronary artery diseases but leptin may be a better marker of extent of CAD than either L/A ratio or adiponectin separately.

Systematic Review and Meta-analysis of Quality of Work Life in Iran (2011-2017).

BACKGROUND: Quality of work life (QWL) is considered as a universal concept in human resource management and organizational development, and its promotion is the key to the success of organizations' management. Therefore, the present study aimed to evaluate the QWL in Iran through systematic review and meta-analysis. METHODS: In this study, all articles related to the QWL in Iran during the years 2011-2017 were systemically reviewed by searching national and international databases such as Science Direct, PubMed, Scopus, Web of Science, Springer, SID, Magiran, Barakat Knowledge Network System, Medlib, and the Google Scholar search engine using valid keywords. The results of the studies were combined using the random effects model. The heterogeneity of studies was studied using the I2 index. Data analysis was done using STATA ver 11. RESULTS: The mean QWL score of 15,323 samples were 60.13, 36.80, 76.19, 58.90, 68.78, 50.69, 32.24, 8.01, 70.63, 39.70, and 44.41 based on Walton, Casio, Sirgy, Mirsepasi, SF-36, Ghasem zadeh, Dehghan, Dargahi, NIOSH, Venlar, Quality of nursing work life questionnaires, respectively. Meta-regression showed that the QWL of employees had no significant relationship with the sample size and years of research. CONCLUSIONS: The mean score of QWL in Iranian employees was 56.90, with the highest and the lowest score for the questionnaire.

The Effect of Intrathecal Meperidine on Maternal and Newborn Outcomes After Cesarean Section: A Systematic Review and Meta-Analysis Study.

CONTEXT: Spinal anesthesia is the most preferred method for cesarean section. This meta-analysis was performed to determine the effect of minimum and maximum intrathecal doses of meperidine (pethidine) [5 to 40 mg] on the maternal and newborn outcomes after cesarean section. EVIDENCE ACQUISITION: The data were collected through the systematic search in the ISI, PubMed, Scopus, Google Scholar, Barakat, MagIran, SID, Irandoc, and EMBASE medical databases. Eighteen clinical trial studies with 1,494 patients were included. RESULTS: Patients who had received intrathecal meperidine had experienced lower shivering, relative risk [RR] = 0.34 (95% CI = 0.23, 0.48) and longer analgesia, [standard mean difference (SMD)] = 7.67 (95% CI = 1.85, 13.49) after the surgery. Moreover, RR of nausea = 1.37 (95% CI = 1.13, 1.66), vomiting RR = 2.02 (95% CI = 1.28, 3.20), and pruritus RR = 9.26 (95% CI = 4.17, 20.58) was higher in the pethidine group than in the control group. There was no statistically significant difference in the Apgar score at one-minute RR = 0.99 (95% CI = 0.9, 1.09), at five-minute RR = 0.93 (95% CI = 0.87, 1.08), maternal hypotension RR = 1.00 (95% CI = 0.87, 1.15), and maternal sensory and motor blockade durations, SMD = -1.72 (95% CI = -3.78.0.34) and SMD = -4.38 (95% CI = -9.19, 0.44), respectively in the two pethidine and control groups. CONCLUSIONS: Intrathecal meperidine can reduce shivering and increase the duration of postoperative analgesia, though it increases the relative risk of nausea, vomiting, and pruritus. No significant difference was found both in the Apgar score, maternal hypotension, and duration of the motor and sensory block.

Evaluation of Suicide Attempt due to Drug Poisoning in a 7-Year-Old Girl: A Case Report.

Introduction: Suicidal behavior is a worrying issue in children and is a very important indicator of emotional distress in children. Suicide is uncommon in children before puberty. Case Report: Here, a case of a 7-year-old girl who committed suicide by drug poisoning was reported. The child's behavior was assessed using a child behavior checklist (CBCL), in which aggressive behavioral problem was the most important. Her mother had a history of suicide attempts, generalized anxiety, and major depressive disorder over the past year, and her father was a drug abuser. Conclusion: Mental disorders in parents and tensions in the family may be associated with behavioral-emotional difficulties in children and it can lead to dangerous behaviors such as suicide attempts. It is most important to describe the factors that lead to suicide attempt among children and intervention that my help these children.

Fructose Feeding and Hyperuricemia: a Systematic Review and Meta-Analysis.

High fructose feeding has been suggested to involve in several features of metabolic syndrome including hyperuricemia (HP). We designed and implemented a study to determine the effect size of fructose intake and the relative risk of HP based on the type of fructose feeding (diet or solution), duration of treatment (2-6, 7-10, and > 10 weeks), and animal race. The required information was accepted from international databases, including PubMed/MEDLINE, Science Direct, Scopus, and etc., from 2009 until 2019 on the basis of predetermined eligibility criteria. The data selection and extraction and quality assessment were performed independently by two researchers. Results were pooled as random effects weighting and reported as standardized mean differences with 95% confidence intervals. Thirty-five studies including 244 rats with fructose consumption were included in the final analysis. The heterogeneity rate of parameters was high (I2 = 81.3%, p < 0.001) and estimated based on; 1) type of fructose feeding (diet; I2 = 79.3%, solution 10%; I2 = 83.4%, solution 20%; I2 = 81.3%), 2) duration of treatment (2-6 weeks; I2 = 86.8%, 7-10 weeks; I2 = 76.3%, and > 10 weeks; I2 = 82.8%), 3) the animal race (Wistar; I2 = 78.6%, Sprague-Dawley; I2 = 83.9%). Overall, the pooled estimate for the all parameters was significant (p < 0.001). The results of this study indicated that a significant relationship between HP and fructose intake regardless of the treatment duration, animal race, fructose concentration and route of consumption.

The relationship between personality traits and marital satisfaction: a systematic review and meta-analysis.

BACKGROUND: Personality traits can be used to predict an individual's behaviors in different life situations, including marital life situations. Marital satisfaction that is influenced by different factors is a criterion used to assess couples' relationship quality. The goal of the present study was to review Iranian studies on the correlation between personality traits and marital satisfaction. METHODS: In this systematic review, all the related Iranian studies in international databases, including Google Scholar, PubMed, Web of Science (ISI) and Scopus, and national databases, including Scientific Information Database (SID) and MagIran were reviewed. The following keywords and also combinations of them were used to search the databases: "Marital satisfaction," "Personality traits," "Personality factors," "Big five model of personality," and "Iran." RESULTS: A total of 18 correlational studies, without any time limitation, with a total sample of 4049, were reviewed. The following correlation coefficients were found between marital satisfaction and personality traits: r = - 0.439 with neuroticism (95% Confidence Interval [CI]: 0.27-0.60), r = 0.833 with extraversion (95% CI: 0.77-0.88), r = 0.777 with openness (95% CI: 0.70-0.84), r = 0.855 with agreeableness (95% CI: 0.80-0.90), and r = 0.90 with conscientiousness (95% CI: 0.84-0.95). CONCLUSIONS: Couples high in Neuroticism experience lower levels of marital satisfaction, and couples high in Conscientiousness are more satisfied with their marital life.

The relationship between maternal anemia during pregnancy with preterm birth: a systematic review and meta-analysis.

Objective: Iron deficiency anemia is the most common cause of anemia during pregnancy. Other causes of anemia include parasitic diseases, micronutrient deficiencies, and genetic hemoglobin apathies. Maternal anemia during pregnancy is the most important public health problem. Since the relationship between maternal anemia by the months of pregnancy and premature birth has been reported differently in various studies; thus, this study aims to determine the relationship between maternal anemia during pregnancy and premature birth.Methods: This systematic review and meta-analysis article was designed based on the recommendations of PRISMA. This study was performed from 1990 to 2018. Articles extracted using related keywords such as maternal, anemia, premature birth, and pregnancy in databases, including Cochrane, Medline, Medlib, Web of Science, PubMed, Scopus, Springer, Science Direct, Embase, Google Scholar, Sid, Irandoc, Iranmedex, and Magiran. Relative risk and its confidence interval were extracted from each of the studies. The random effects model was used to combine study results and heterogeneity among the studies measured using I2 index and the data were analyzed based by using STATA software version 3.2.Results: Overall 18 studies with sample sizes of 932 090 were entered into the meta-analysis. The overall relationship between maternal anemia during pregnancy and premature birth was significant (1.56 [95% CI: 1.25-1.95]). Maternal anemia in the first trimester increases the risk of premature birth (relative risk, 1.65 [95% CI: 1.31-2.08]). But, this relationship was not significant in the second (relative risk, 1.45 [95% CI: 0.79-2.65]) and third trimester (relative risk, 1.43 [95% CI: 0.82-2.51]).Conclusion: Maternal anemia during pregnancy can be considered as a risk factor for premature birth.

Prevalence of unwanted pregnancy among Iranian women: an updated meta-analysis.

BACKGROUND: Unwanted pregnancy is a global issue with adverse outcomes for the mother, child, family, and society. Previous studies in Iran have reported different prevalence rates for unwanted pregnancy. This meta-analysis was aimed at estimating the overall prevalence of unwanted pregnancy among Iranian women. METHODS: A total of 20 articles in English or Persian, published between 2012 and December 2018, were collected. The search was conducted in national and international databases, including Scientific Information Database (SID), MagIran, PubMed, Scopus, and Web of Science, using the following keywords: 'Unplanned pregnancy', 'Unintended pregnancy', 'Unwanted pregnancy', and 'Mistimed pregnancy'. The data were analyzed using the meta-analysis method and the random effects model. Heterogeneity among studies was assessed using the I2 statistic. All analyses were performed using Stata, version 12. RESULTS: Analysis of 20 studies with a total sample size of 16,298 showed that the prevalence of unwanted pregnancy among Iranian women was 26% (95% Confidence Interval [CI]: 23-28). This prevalence was higher in the regions 5 and 2 of Iran (27%) than the other regions, and had no significant decrease between 2012 and 2018 (p = 0. 937). CONCLUSION: More than one-fourth of pregnancies among Iranian women are unwanted. Providing training programs for couples who do not plan to have children along with the support policies aimed at stimulating population growth, can be an important step in overcoming the issue of unwanted pregnancy and reducing the illegal abortions related to it.

Biochemical parameters of rickets in Iranian children: A systematic review and meta-analysis.

BACKGROUND: Many causes can lead to childhood rickets. We aimed to investigate the biochemical symptoms of childhood rickets with systematic review and meta-analysis. MATERIALS AND METHODS: Seven articles published from 1975 to 2018 were recruited. The literature search was performed in the Scientific Information Database, Google Scholar, PubMed, and Elsevier databases using related keywords. For meta-analysis, the results of the studies were pooled using the random-effects model. The heterogeneity between the studies was checked using Q test and I 2 index. RESULTS: The total sample population consisted of 933 children with biochemical symptoms of rickets (133 participants per article). According to our findings, the mean serum levels of PO4, Ca, and alkaline phosphatase in children with rickets were 4.18 (95% confidence interval [CI]: 3.75-4.61, I 2 = 98.3%, P < 0.001), 9.23 (95% CI: 8.78-9.68, I 2 = 99.6%, P < 0.001), and 1.33 (95% CI: 1.23-1.44, I 2 = 95.6%, P < 0.001), respectively. CONCLUSION: Characterizing the biochemical symptoms of rickets in children can help to early diagnose and prevent the disease in children. Furthermore, educating parents about biochemical symptoms can lead to early diagnosis and successful treatment of rickets in children.

The relationship between body mass index and preeclampsia: A systematic review and meta-analysis.

BACKGROUND: One of the causes of maternal and fetal mortality and morbidity is pregnancy-induced hypertension, the most common form of which is preeclampsia that causes many complications for mother and fetus. OBJECTIVE: The aim of this systematic review and meta-analysis was to determine the relationship between body mass index (BMI) and preeclampsia in Iran. MATERIALS AND METHODS: Using valid keywords in the SID database, PubMed, Scopus, data obtained from all the articles, which were reviewed in Iran between 2000 and 2016, were combined using the meta-analysis method (random-effects model) and analyzed using STATA version 11.1. RESULTS: A total number of 5,946 samples were enrolled in 16 studies with the mean BMI values of 25.13, 27.42, and 26.33 kg /m 2 in the healthy, mild, and severe preeclamptic groups, respectively. CONCLUSION: The results of this study revealed that there is a significant relationship between BMI and the risk of preeclampsia, so it can be said that BMI may be one of the ways to diagnose preeclampsia.

Is there association between Trichomonas vaginalis infection and prostate cancer risk?: A systematic review and meta-analysis.

We performed a systematic review and meta-analysis to reveal the association between Trichomonas vaginalis (TV) infection and the risk of prostate cancer (PCa) development. Systematic searching (PubMed/Medline, Scopus, Embase, Web of Science, Cinhal, Wiley, Cochrane, Psychoinfo, ProQuest and Google Scholar) was done, up to March 2018 for case-control studies. Random effects model was applied to define odds ratios and their 95% confidence intervals. In total, 6 enteries were included in our meta-analysis, comprising 5590 individuals (2677 PCa cases and 2913 control individuals) examined for trichomoniasis, with a total positivity of 469 (17.51%) and 482 (16.54%) individuals, respectively. Totally, such association was documented in three countries, including USA (4 studies), Kuwait (one study) and Taiwan (one study). Based on pooled estimations, however a 1.17-time increase of PCa was observed among individuals with a previous exposure of TV, it was not statistically significant [OR = 1.17 (95% CI: 1.01 to 1.36)]. Egger's regression test demonstrated no publication bias among studies. Also, year of publication for included records was not significantly correlated to the relationship between trichomoniasis and PCa. Any further inferences should be based on future investigations for better understanding this relationship and shedding light on the cryptic pathogenesis of TV in PCa patients.
