Previous studies conducted on the association between diabetes and the risk of endometrial cancer have reported controversial results that have raised a variety of questions about the association between diabetes and the incidence of this cancer. Thus, the aim of this systematic review and meta-analysis was to more precisely estimate the effect of diabetes on the risk of endometrial cancer incidence. All original articles were searched in international databases, including Medline (PubMed), Web of sciences, Scopus, EMBASE, and CINHAL. Search was done from January 1990 to January 2018 without language limitations. Also, logarithm and standard error logarithm relative risk (RR) were used for meta-analysis. A total of 22 cohort and case-control studies were included in this meta-analysis, of which 14 showed statistically significant associations between diabetes and risk of endometrial cancer. Diabetes was associated with increased risk of endometrial cancer (RR = 1.72, 95% CI 1.48–2.01). The summary of RR for all 9 cohort studies was 1.56 (95% CI 1.21–2.01), and it was 1.85 (95% CI 1.53–2.23) for 13 case control studies. The summary of RR in hospital-based studies was higher than other studies. Thirteen of the primary studies-controlled BMI as a confounding variable, and the combined risk of their results was 1.62 (95% CI 1.34–1.97). Diabetes seems to increases the risk of endometrial cancer in women, and this finding can be useful in developing endometrial cancer prevention plans for women having diabetes.

Background: Several reports have demonstrated varying results on the quality of life (QoL) of the transgender population. Therefore, the aim of this study was to conduct a systematic review and meta-analysis about the quality of life (QoL) of individuals during the post transsexual surgery period. Methods: We searched major biomedical electronic databases, including Scopus, Google Scholar, Psychological Information Database (PsycInfo), Web of Science, PubMed, Excerpta Medica dataBASE (EMBASE), and ProQuest, for all relevant literature published in English up to December 2019. The included papers required to be cross sectional studies that reported quality of life in people with transsexuality post surgery. After selecting eligible studies, 2 authors extracted data of each study independently and resolved any inconsistency by consensus with the third reviewer. The risk of bias was assessed by 2 independent research experts by the Newcastle-Ottawa Scale (NOS). Results: In this study, out of 497 articles extracted from the initial investigation, 8 articles with 1099 patients were ultimately selected for meta-analysis. The pooled mean of quality of life in transsexual individuals was obtained to be 70.45 (95%CI 55.87–85.03) and 59.17 (95%CI 48.59–69.74), based on World Health Organization Quality of Life (WHOQoL-BREF) and The 36-item short form of the Medical Outcomes Study questionnaire (SF36), respectively. Also, the results of the subgroup analysis for the weighted mean quality of life in male to female and female to male showed that the mean quality of life in female to male was 57.54 (95%CI 42.24–72.84) and it was 62.47 (95%CI 45.94–79.00) in male to female, based on SF36 questionnaire. Moreover, the weighted mean quality of life in female to male was 69.99 (95%CI 43.76, 96.23) and it was 70.65 (95%CI 53.11, 88.19) in male to female, based on WHOQoL-BREF questionnaire. Conclusion: The results of this systematic review may support the approaches to transsexuality that facilitates sex reassignment. In this review, the means of quality of life after surgery were not compared to the means of quality of life before surgery or even before hormonal therapy which was due to inadequate number of primary studies.

Objective Anemia is a major problem in developing countries, the purpose of the present study was to investigate the relationship between the human development index (HDI) and the prevalence of anemia among Asian women. Methods This was a descriptive-analytic ecological study. The study analyzed data including HDI and prevalence of anemia extracted from the World Bank. The correlation coefficient and analysis of variance were used for data analysis. The significance level was considered to be less than 0.05. Analyses were performed using Stata-14 software. Results The results revealed that the prevalence of anemia in women of reproductive age (R=-0.626, P<0.001), pregnant women (R=-0.576, P<0.001) and non-pregnant women (R=-0.623, P<0.0001) was significantly negatively correlated with HDI index. In the analysis of HDI components and the prevalence of anemia, a significant negative correlation was observed between the prevalence of anemia and the mean years of schooling, life expectancy at birth, and expected years of schooling indices in all 3 groups of women (non-pregnant, pregnant, and of reproductive age) (P<0.05). Conclusion Since there was a negative correlation between the prevalence of anemia in women and HDI, paying greater attention to factors which influence anemia may contribute to the prevention of anemia in developing countries.

Introduction: Chronic diseases, due to their prolonged and debilitating nature, dramatically affect patient quality of life. Allergic rhinitis (AR) is one of the most common chronic diseases. The present study aimed to determine quality of life in patients with allergic rhinitis in Western Iran. Methods: In a cross-sectional study, 146 patients with AR were enrolled in this study. The required data were collected using the Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ). The questionnaire was distributed among the patients by a physician and analysis of data was carried out by SPSS version 16. Results: Of the total of 146 AR patients admitted to the clinic, 61% were female and 39% were male; the mean age was 29±10.17. Rhinorrhea (82.2%) was the most common symptom, and moderate to severe intermittent rhinitis (38.4%) was the most common type of the disease. A dramatic reduction in quality of life was observed in 62% of the patients, and the severity of the disease significantly reduced the quality of life (P=0.000). Conclusion: Allergic rhinitis can adversely affect every aspect of a patient's life, including sleep quality, mood and daily activities.

Objective: Pancreatic cancer is one of the leading causes of mortality in developed countries and a lethal malignant neoplasm worldwide. This study aims to evaluate the epidemiology of pancreatic cancer incidence and mortality and its relationship with HDI. Methods: This is a descriptive cross-sectional study that is based on cancer incidence data and cancer mortality rates derived from the GLOBOCAN in 2018. The incidence and mortality rates of Pancreas as well as Pancreas cancer distribution maps were derived for world countries. The data analysis was conducted using a correlation test, and regression tests were used to evaluate the correlation of the incidence and mortality of Pancreas with HDI. The statistical analysis was carried out by Stata-14, and a significance level of 0.05 was considered. Results: The highest incidence of pancreatic cancer was reported in Asia with 214499 (46.7%) cases and the lowest incidence was related to Oceania with 4529 cases (0.99%). The results showed a positive and significant correlation between incidence (r = 0.764, P <0.0001) and mortality (r = 0.771, P <0.0001) of pancreatic cancer and the HDI index. The results of ANOVA revealed that the highest mean incidence was related to the very high HDI (P <0.0001) and the highest mortality was connected to the very high human development (P <0.0001). The results exhibited that incidence was positively and significantly correlated with GNI (r = 0.497, P <0.0001), MYS (r = 0.746, P <0.0001), LEB (r = 0.676, <0.0001) and EYS (r = 0.738, P <0.0001). Also, a significant positive correlation was found between mortality and GNI (r = 0.507, P <0.0001), MYS (r = 0.745, P <0.0001), LEB (r = 0.679, <0.0001), and EYS (r = 0.748, P <0.0001). Conclusion: Given the higher incidence and mortality of pancreatic cancer in countries with HDI, it is necessary to pay a greater attention to risk factors and appropriate planning to reduce these factors and minimize the impact and mortality rate of this disease.
