The Modification of the Education System in a Medical Faculty in Iran During the COVID-19 Outbreak

Background: The coronavirus disease 2019 (COVID-19) pandemic has had an important effect on medical education. Universities around the world responded to the crisis by announcing the immediate closure and substituted the in-person sessions with online ones.Methods: Iran University of Medical Sciences designed a platform for medical students. To maintain the social distance, only onethird of students living in the dormitory were present at the dormitory in this condition. Some training courses were divided into two parts and each group was supposed to participate in given courses in-person for 15 days. The crash courses were trained on all days of the week. Then, the first group left the dormitories and was replaced with the second group, and they used dormitories for 15 days after being disinfected. Besides, for the best use of time, students who could not present in these 15-day training courses took part in virtual training programs.Results: It is depopulate the educational sessions at hospitals and classes in educational sectors. Besides, using the virtual classroom software given by the university, students can take part in virtual training programs.Conclusion: Using this platform, the number of trainees, as well as the gathering of students at dormitories, was reduced

Prognosis and Complications of Attempted Suicidal Hanging

Background: Hanging is a form of strangulation, in which the body is suspended through the neck and the weight of the body acts as a constricting force. This study assessed various factors on the outcome of hanging and identification of prognostic factors related to the outcomes.Methods: Ninety-nine hanging victims from 1995 to 2015 in Iran were evaluated; then, variables such as the cause of death, distribution of mortality, duration of hospitalization, substance abuse consumption, respiratory distress, and cerebral edema were studied in these people. Finally, the data were analyzed.Results: Major cases of suicide by hanging were men. In connection with prognosis, about 12% of the deaths occurred in men and about 21% were represented in women. More importantly, in the matter of suspension, the model was largely incomplete to complete. Also, the outcomes of pulmonary stress and cerebral edema were recognized in association with the type of hanging and mortality prognosis.Conclusion: Only two risk factors, including loss of consciousness at the time of entry into the medical center, as well as the complete suspension, would be predictive operations of death and unsuccessful revival

Epidemiology of Completed Suicides Referred to Forensic Pathology Organization of Tehran, Iran, During March 2011 to March 2016

Background: Completed or successful suicide is the worst outcome of suicide attempts. This study is an epidemiologic investigation of successful suicides in Tehran, Iran.Methods: In this routine-data-based study, the records of successful suicides in Forensic Pathology Organization of Tehran were investigated with respect to confidentiality of information during March 2011 to March 2016. The obtained data were analyzed by SPSS 11.5. Statistically significant level was considered at less than 0.05.Results: A total of 1773 cases with mean (SD) age of 33.19(13.11) years and male-to-female ratio of 3.1 were included in the study. The mean age of male victims was greater than that of female ones (P=0.01). Of victims, 821(46.3%) were single and 807(45.5%) were unemployed/housewife. Methods of suicide were hanging in 962(54.6%), poisoning in 640(35.8%), falling in 88(5%), burning in 35(2%), shooting in 29(1.6%) and others in 19(1%) cases. Of poisoned cases, 283(44%) were victims of aluminum phosphide ingestion. Generally, frequency of married victims was greater than single ones but by comparing genders, relative frequency of single victims was greater among males (P<0.001). There was statistically significant association between suicide methods and age (P=0.001), gender (P<0.001), and occupation (P<0.001) of victims. Among different methods, shooting and poisoning were used by the youngest cases. Relative frequency of females was greatest in victims of burning and poisoning. Regarding occupational categories, poisoning was most frequent in students.Conclusion: In this study, the majority of successful suicides happened in people with occupational uncertainty, thus preventive measures should prioritize this issue. It seems that women with marital problems are also prone to suicide and social support programs should target this group, too. Association between the method of suicide and demography of victims will help us to recognize common methods in various groups of the society and establish appropriate preventive measures. While limiting access to supplies of suicide (like legislation on distribution of drugs for prevention of poisoning) is valuable, fundamental interventions at community level will be more effective in prevention of all kinds of suicide

Research Paper: Gender Identification With Knee Bicondylar Width and Vertical Diameter of the Femur Head Based on Radiography Assessment

Background: Some skeletal criteria especially for bones of lower limbs are considerably different between men and women that may help in identifying the gender. We studied two lower limbs parameters, i.e. bicondylar width and vertical diameter of the femoral head based on radiographic assessment in gender identification.Methods: Bicondylar width and vertical diameter of the femoral head of 280 radiographs taken from people aged 30 to 75 years were measured. Additionally, gender and age subgroups were recorded and added to the measured anthropometric parameters in the checklist of the study.Results: The mean width of both left and right bicondylar bones as well as vertical diameter of both left and right femoral heads were significantly different between men and women. Considering two parameters of bicondylar width and vertical diameter of femoral head, the measurements could differentiate gender, with 96.7% sensitivity, 72.2% specificity, and 96.0% accuracy.Conclusion: By measuring bicondylar width and vertical diameter of the femur head, it is possible to determine gender with a high discriminative capability

Investigating Emergency Nurses’ Awareness on the Differentiation Between Acute Methanol and Ethanol Intoxication

Background: Alcohol intoxication is among the leading and preventable causes of death, disability, and injury in numerous societies. Ethanol and methanol are the most commonly used types of alcohol. Increasing nurses’ awareness about the difference between intoxication with these two alcohol types will prevent the occurrence of dangerous and deadly complications of intoxication. We investigated the awareness of the nurses respecting the difference between acute methanol and ethanol intoxication in clinical manifestations, diagnosis, and treatment.Methods: A cross-sectional study was performed in 2020 on the emergency nurses from two educational hospitals. A total of 100 nurses participated in this study. The data collection tool was a researcher-made questionnaire, including demographic characteristics and questions concerning the identification and differentiation of acute methanol from ethanol intoxication. Moreover, the obtained data were analyzed using SPSS v. 20 at the significance level of P<0.05. Results: The present research results suggested that 21% of the examined nurses had a low level of awareness (<7) and 79% had a moderate level of awareness (8-13). The mean score of awareness was measured as 8.71 (range: 2-12). Nurses’ awareness was not related to age, gender, the duration of working experience, and educational level (P>0.05).Conclusion: The awareness of nurses regarding alcohol poisoning is moderate. Due to the importance of differentiating ethanol from methanol toxicity, considering the outcomes of the patients, nurses’ awareness should be increased

Ischemic heart disease risk factors in lead exposed workers: research study

Background: Review of other epidemiological studies reveal inconsistent results of relationships between high blood lead level and risk of hypertension, hyperlipidemia and hyperglycemia. In this study we wanted to find if there is a relationship between blood lead level and these ischemic heart disease risk factors. Methods. This cross-sectional study was conducted in a battery recycling plant, and 497 male workers with the mean age of 41.7 (±6.50) years were recruited from all over the plant (those from the products and maintenance sections were classed as "high lead exposed group" and those from amongst the office, laboratory, security services and food services sections as "low lead exposed group"). Personal information such as demographics and work history was obtained through a questionnaire. Mean (±Standard deviation) for quantitative variables, Frequency (Percent) for qualitative variables, and Odd's ratio (OR) with 95 confidence interval (95 CI) for estimating the effect of blood lead level on lipid profiletriglyceride (TG), cholesterol(CHOL), low density lipoprotein - Cholesterol(LDL-C),high density lipoprotein -Cholesterol(HDL-C), hypertension(HTN) and fasting blood sugar (FBS) level. Logistic regression modeling was used for multivariate analysis and adjusting the effect of different variables (age, body mass index(BMI), eating habits, cigarette smoking). Results: The mean Blood Lead Level (BLL) was >40 μg/dl in 281 (56.6%) subjects, �40 μg in 216 (43.4%) subjects and the mean BLL was 43.3 μg/dl (n = 497). The mean job experience involving lead exposure was 13 years. There was no significant correlation between BLL and FBS (p = 0.68), between BLL and TG (P = 0.32), between BLL and HDL-C (p = 0.49), between BLL and LDL-C (p = 0.17), between BLL and CHOL(p = 0.96), between BLL and systolic blood pressure (p = 0.12). The adjusted Odd's ratio for the effect of BLL >40.0 μg/dl on diastolic blood pressure was1.03 (95% CI: 1.01-1.05) with p = 0.05. Conclusion: This study showed an association of high BLL with diastolic blood pressure but not with TG, FBS, and HDL-C, LDL-C and CHOL. This result persisted even after adjustment was made for age, BMI and job experience, smoking and eating habits. Attention to health-protective policies, individual behavioral changes and regular periodic medical examination with focus on diastolic blood pressure in lead exposed workers is likely to decrease the public health burden of ischemic heart disease. © 2013 Ghiasvand et al.; licensee BioMed Central Ltd

The Value of Foramen Magnum Diameters for Gender Identification Among Iranian Population

Background: By assessing the size of the foramen magnum, it is possible to distinguish two genders, as well as the intergenerational interdependence of the affected individuals. The present study aimed at assessing the value of diameters of foramen magnum for gender identification among the Iranian population.Methods: This analytical comparative cross-sectional study was performed on 200 Iranian cadavers (100 men and 100 women) referred to Kahrizak Autopsy Hall in Tehran between 2017 and 2018. In each case, the foramen magnum was measured by observation and its parameters were measured in a longitudinal anteroposterior and transverse diameter, using a calibrated caliper.Results: The Mean±SD anterior-posterior diameter of the foramen magnum in men and women were 35.59±0.49 mm and 33.90±1.07 mm, respectively, which was significantly higher in men (P<0.001). Similarly, the Mean±SD transverse diameter of the foramen magnum in males and females was 29.49±0.56 mm and 28.5±0.50 mm, respectively, which was significantly higher in men (P<0.001). Based on the area analysis under the Receiver Operating Characteristic (ROC) curve, the anterior-posterior and transverse diameters of the foramen magnum had a high value in the differentiation of the male and female genders (AUC=0.953 and 0.896, respectively, P<0.001). The Mean±SD foramen magnum index in men and women was 84.15±3.02 and 82.87±1.95, respectively, which had a significant difference between the two genders.Conclusion: Given that the anterior-posterior and transverse diameters of the foramen magnum in Iranian men are far more than Iranian women, these diameters can be used to distinguish between the two genders in the precise legal field

Sleep patterns and habits in high school students in Iran

<p>Abstract</p> <p>Background</p> <p>Sleep patterns and habits in high school students in Iran have not been well studied to date. This paper aims to re-address this balance and analyse sleep patterns and habits in Iranian children of high school age.</p> <p>Methods</p> <p>The subjects were 1,420 high school students randomly selected by stratified cluster sampling. This was a self-report study using a questionnaire which included items about usual sleep/wake behaviours over the previous month, such as sleep schedule, falling asleep in class, difficulty falling asleep, tiredness or sleepiness during the day, difficulty getting up in the morning, nightmares, and taking sleeping pills.</p> <p>Results</p> <p>The mean duration of night sleep was 7.7 h, with no difference between girls, boys, and school year (grade). The mean time of waking in the morning was not different between genders. About 9.9% of the girls and 4.6% of the boys perceived their quality of sleep as being bad, and 58% of them reported sleepiness during the day. About 4.2% of the subjects had used medication to enhance sleep. The time of going to bed was associated with grade level and gender. Sleep latency was not associated with gender and grade leve, l and 1.4% experienced bruxism more than four times a week.</p> <p>Conclusion</p> <p>Our results are in contrast with that of previous studies that concluded sleep duration is shorter in Asia than in Europe, that boys woke-up significantly later than girls, and that the frequency of sleep latency category was associated with gender and grade level. The magnitude of the daytime sleepiness, daytime sleepiness during classes, sleep latency, and incidences of waking up at night represent major public health concerns for Iran.</p
