Conclusion The findings showed a significant inequality in the most of the noncommunicable diseases in the region, which are more concentrated among the poorest population. Policymakers in the health system and city planners should consider these results to decrease the burden of noncommunicable diseases in the society by identifying vulnerable subcategories.Background Given the various reports of the clinical spectrum of the disease, the aim of the present study was to determine possible scenarios of Coronavirus 2019 (COVID-19) iceberg using published articles. Methods The present study was a rapid review of all international databases, including PubMed (Medline), Scopus, Web of Sciences, Embase, and Cochrane Library from January 1 to October 30, 2020. Results In this review, 7 scenarios were considered for COVID-19 iceberg, in which the range of fatality percentage was estimated to be 0.5% to 7%, the range of asymptomatic cases 1% to 88.6%, the range of cases with mild symptoms 8% to 78%, no symptoms 1 % to 90 %, the range of intensive care unit (ICU) admission was 0.5% to 14.2%, and finally the intubation percentage was estimated to be 0.2% to 12.2%. The Scenarios Diamond Princess Cruise Ship and Iceland are closer to the reality of the clinical spectrum of COVID-19 around the world, which represent 0.6% and 0.5% of deaths, 0.7% and 1% of intubations, 2.5% and 9.7% of ICU admissions, 1.1% and 6% of hospitalizations, 15% and 31% of cases with mild symptoms, and finally 56.9% and 75% of asymptomatic cases of COVID-19, respectively, which should now be considered as the basis of the clinical knowledge of the disease. Conclusion Understanding the clinical spectrum and natural knowledge of the disease and paying attention to asymptomatic or mild-symptom cases can help to make better decisions and develop more effective interventions to control COVID-19.Background Using morphologic features of the bones is the basis of gender determination in anthropology and forensic medicine. In this study, we evaluated the calcaneus diameters for gender determination in the Iranian population. Methods This cross-sectional study was conducted on Iranians referring to Hazrat-e Rasool Hospital's radiology ward for plain lateral X-ray of the foot. Lateral foot X-rays from 100 men and 100 women were gathered and evaluated for calcaneal indexes. These patients aged between 18 and 80 years old who did not suffer major trauma to the calcaneus bone were recruited. Using a picture archiving and communication system (PACS), four variables were calculated for each X-ray graph Maximum anterior-posterior length of the calcaneus (MAXL), Maximum height of the bone (MAXH), Height of the cuboid facet (CFH) and Height the calcaneal body (BH). Cut off points for each index were calculated using the area under curve (AUC) in ROC curves. Results Lateral foot X-rays from 100 men and 100 women were gathered and evaluated for calcaneal indexes. The means of the four indexes were compared between the sexes which showed all four means are significantly different p value less then 0.001. AUC for MAXL in differentiating the genders was 0.824, which showed 86.8 as the cut off with a sensitivity of 80% and specificity of 69.0%. Cut off point for MAXH was set at 59.8 with sensitivity and specificity of 78.0% and 60.0%, respectively. For BH, 49.5 was set as the cut off point with a sensitivity of 79.0% and specificity of 64.0%. The best cut off point for CFH was 27.8 with 76.0% sensitivity and 63.0% specificity. Conclusion It can be concluded that the calcaneal diameters are reliable criteria for sex determination. Although the cutoff points are different between various races and populations, it is evident that these diameters can be used for sex determination in general.Background Gastroesophageal reflux disease (GERD) is a prevalent condition. Erosive esophagitis (EE) and Barrett's esophagus (BE) are the two important complications of GERD. We aimed to study the prevalence of EE and BE in a group of Patients with reflux symptoms who were referred for endoscopy.  https://www.selleckchem.com/  The relationship between reflux symptoms and endoscopic findings was also examined. Methods We enrolled 139 consecutive patients with characteristic symptoms of GERD. Demographic and clinical characteristics of the patients including duration and severity of reflux symptoms, were recorded. Endoscopic findings of EE were identified and classified according to the Los Angeles classification, while BE was confirmed by histopathology examination. The Fisher's exact test and the two-sample Background One of the most important aspects of life is reproductive health, which receives less attention in public policy considerations because of its sociopolitical sensitivities. The aim of this study was to evaluate the effect of a designed health education program on knowledge about puberty health among visually impaired female adolescent students during 2011 and 2015. Methods This quasi-experimental study was conducted on 100 visually impaired female students aged 10 to 19 years. Data collection tool was a researcher-made questionnaire. Participants were recruited using convenience sampling method from Narjes educational center in Tehran. The educational needs assessments survey was used to learn about important issues and problems faced by this group to design effective educational programs. The effectiveness of the designed program was assessed by comparing the students' knowledge at the baseline and at 1-month follow-up. Data were analyzed in SPSS V.21 by using parametric descriptive statistics. The significant level was set as p less then 0.05 Results The results showed that the puberty knowledge of participants was increased in all educational domains after intervention compared to the baseline (p less then 0.05). The knowledge about the onset of puberty changes showed the highest increase (from 2.02 at baseline to 7.51 at follow-up) and the knowledge about personal hygiene had the least change after the intervention (from 6.67 to 8.23). The majority of students did not have any information resources regarding puberty health, and about one quarter of them reported their mother as the main resource of puberty information. Conclusion Providing educational programs during puberty has a crucial role in young girls' knowledge increase. Providing a continuous health educational program that is tailored to the needs of this group of students using suitable strategies is recommended.
