summary A Web-based educational model, called JUTE, was developed for the early diagnosis of melanoma. It was compared with a control Website composed of information available on the Internet for teaching undergraduate medical students. The JUTE model was designed to allow the student linear navigation of the main topics that were assumed to be important in learning to make a diagnosis. The rate of success in correctly deciding to refer pigmented lesions to a dermatologist was compared among 34 new medical students who were randomly divided into two groups. There was no significant difference between the JUTE and control groups in the pre-test. When comparing the pre- and post-tests, the number of correct decisions increased significantly only in the JUTE group. In the JUTE group there was a slight but significant improvement when comparing decisions about thin melanoma before and after the training. The educational approach chosen for the JUTE Website appears to be useful for teaching the early recognition of melanoma and could be used for larger educational campaigns of skin cancer prevention.

In the present era, mobiles and other digital display devices have become an essential part of our daily life. But due to the COVID-19 pandemic curfew, the use of digital gadgets has increased many folds, with direct proportion to increased health risks, especially eyes. In this study, we aim to assess the prevalence, risk factors and symptomatology of Digital vision syndrome (DVS) among medical students during the COVID-19 lockdown. This is a descriptive cross-sectional questionnaire-based study. The undergraduate medical students were asked to fill an electronic self-administered survey. The survey included questions regarding their digital device usage before and after the curfew and various factors related to DVS. Among 250 medical students during this lockdown period, it was observed the screen time or hours spent on using a digital screen by the respondents increased significantly in the 2-3 hours and 3-4 hours category and a significant difference (p=0.000) was observed in 1% level of significance in pre and post lockdown. No significant change was observed in the type and illumination of gadgets used. Around 60% of the students were in intensive lockdown, and up to 51% of the students felt the upsurge in DVS symptoms. Nearly 82.3% of students experienced one or more symptoms of DVS. The most commonly reported symptom was headache which shot up after the lockdown to 51.6% from 32.7%. It was followed by eye strain and dry eyes, which increased from 19.5% to 40.3% and 10% to 21% respectively after curfew. During the COVID-19 pandemic lockdown, there appeared to be an exacerbated increase in DVS symptoms among medical students, one of the leading reasons being increased screen time. A significant association was found between the rise in symptoms and intensive lockdown.

ABSTRACT Plasma levels of testosterone (T) and 5α-dihydrotestosterone (DHT) were determined by radioimmunoassay in 29 patients with benign prostatic hypertrophy (BPH) and in 56 control men of various ages. No significant difference was found in T, DHT nor DHT/T ratio between BPH and control subjects of similar age. Plasma DHT was higher in the prostatic than in the peripheral veins in 8/9 patients with BPH during laparotomy, indicating a prostatic secretion of DHT. No difference in the mean T nor the mean DHT was found in peripheral plasma before and after adenomectomy.

Background and Objective: Subclinical hypothyroidism can potentially develop to overt hypothyroidism. Thyroid hormones have substantial roles in metabolism and glucose homeostasis and thus are closely related to determinant factors of metabolic syndromes, such as obesity and insulin resistance. Osteocalcin is considered a predictor of metabolic conditions in thyroid diseases. This study aimed to investigate the effect of levothyroxine vs. placebo on serum osteocalcin levels in patients with subclinical hypothyroidism. Methods: This randomized clinical trial was performed on 30 patients with subclinical hypothyroidism who were referred to the endocrine clinics of Ghaem and Imam Reza hospitals in Mashhad, Iran. After giving informed consent, patients were randomly divided into intervention (50 µg/day levothyroxine for 2 months) and control (placebo) groups. Serum levels of osteocalcin, thyroid hormones, lipid profile, insulin, and fasting glucose, as well as other clinical and anthropometric data, were measured at baseline and at the end of the study. SPSS was used to analyze the data and P<0.05 was considered significant. Results: Mean age in the intervention and control groups was 35.07 ± 9.94 and 31.30 ± 4.30, respectively (P=0.20). There was no significant difference between osteocalcin levels before and after the intervention in either of the groups (P=0.54). TSH level was significantly decreased in the levothyroxine group after the intervention (P<0.01). T4 level was significantly increased in the intervention group (P=0.02). Conclusion: Levothyroxine had no significant effect on increasing the levels of serum osteocalcin in patients with subclinical hypothyroidism. We have registered the trial in the Iranian registry of clinical trials (IRCT) with the registration code IRCT20171129037677N1.

Abstract Background Sudden cardiac arrest considers one of the most leading cause for death in all over the world. It is important for all medical students to train basic life support. This study evaluated the awareness of basic life support among medical students. Methods An electronic questionnaire based cross sectional study was conducted in November 2020 among 2114 medical student in Syria, Iraq and Jordan. We evaluated BLS skills according to mean score. A chi-squared test was used to determine if there were differences between those who attended a basic life support course and those who did not. Results 1656 of the participants (78.3%) stated that they did not attend a basic life support course. There was a significant difference between the participants from different countries where the mean score in Syria, Jordan and Iraq was 18.3, 24.3 and 18.8 respectively (p < 0.05). The participants were divided into 3 level according to total score; low (0–12), moderate (13–24) and high (25–37). In total, 18.3%, 72.8% and 8.9% of participants had high, intermediate and low level respectively. Conclusions The overall knowledge of basic life support among medical students is not adequate and need significant improvements. This study showed that an attendance a basic life support course previously had an effect on knowledge level. Hence, there is an urgent need to apply basic life support courses into the pre-clinical stage at universities.

The Impact

More people working at offices are choosing to eat meals at their desks, making “desktop dining” an increasingly common phenomenon. Previous studies have reported that environmental distractors, such as television viewing, can influence meal intake and subsequent snack intake. However, the impact of stressful mental tasks on eating behavior has received relatively less attention, focusing only on subsequent meal intake or concurrent snack intake. This study sets out to determine whether eating while working influenced current meal energy intake. This research also examined the relationship between dietary restraint status and energy intake. A crossover experimental design was employed requiring participants (14 males and 29 females) to eat pizza quietly and at rest (control), and while working on a computer (work). Measurements included BMI, energy intake, state anxiety, restrained eating behavior, stress levels (pre- and post-eating), and appetite (before and after both work and control sessions). The findings showed that consuming food while working on a computer significantly increased stress but had no influence on energy intake compared to the control condition. However, post-eating hunger levels were significantly higher in the work condition compared to the control condition. As expected, satiety levels decreased significantly from pre- to post-eating for both work and control conditions. In addition, no significant relationship was observed between restrained eating behavior and energy intake in both work and control conditions. These results suggest that eating while working affected satiety of normal weight participants, as indicated by the significant difference in post-meal satiety levels between work and control conditions.

Introduction The aim of this study is to investigate the effect of cigarette smoke on turbinate reactivity and mucociliary clearance (MCC) in passive smokers. Methods 60 adult patients (30 passive smokers and 30 healthy subjects as the control group) were recruited for this study. Following a questionnaire on passive smoke exposure, MCC measurement using the saccharin test was carried out to all participants. The baseline and after decongestant acoustic rhinometry values (MCA1, MCA2, VOL1, VOL2) were measured and the percentage changes between the two test values (ie; response to nasal decongestants = concha reactivity) were recorded. Results All 60 patients, including 37 women (61.7%) and 23 men (38.3%) were between 18–57 years of age . MCC’s average measurements were 11.13 minutes in the passive smokers group, 7.87 minutes in the control group, which was statistically significantly different (p < 0.05). There was a statistically significant difference between the passive smokers and control group for acoustic rhinometric measurement of the ratio of MCA2 and VOL2 values before and after decongestant application (p < 0.05). Discussion Passive smoking can damage the nasal mucosa at least as active smoking. The number of studies on this subject is limited. There are no studies in the literature showing the effect of cigarette smoke on the inferior turbinate mucosal response. In our study, the inferior turbinate decongestant capacity was found to be significantly decreased in the passive smokers compared to the control group. Conclusion As a result of cigarette exposure, the erectile function of the lower turbines may be impaired. The task of the ENT physicians is to warn the passive smokers in this regard.

Background: The present study aimed to evaluate the effect of cold dialysis solution on the sexual dysfunction of patients with chronic renal failure undergoing hemodialysis. Methods: This randomized clinical trial was conducted with a before and after parallel design among 60 hemodialysis patients diagnosed with sexual dysfunction. The selected subjects were randomly allocated to the two groups of experimental and control (30 per each). Patients in the experimental and control groups underwent hemodialysis for one month using 35.5°C and 37°C dialysis solutions, respectively. Following the procedure, male and female sexual function was assessed in the study groups. Data were collected using the International Index of Erectile Functions, the female sexual function index (FSFI), and a demographic questionnaire. Data analysis was performed using Chi-square, Fisher's exact test, Mann-Whitney U test, t-test, paired t-test, and Wilcoxon test at 95% confidence interval. Results: No significant difference was observed between the experimental and control groups regarding male sexual function before and after the intervention (P > 0.05). However, the Mann-Whitney U test indicated a significant difference in the female subjects’ arousal in the experimental group before (3.68 ± 0.38) and after the intervention (3.98 ± 0.46; z = 2.216; P = 0.027). Conclusions: Cold dialysis solution could only increase the sexual arousal of the women in the experimental group, and no changes were observed in other sexual function domains of the male and female patients. Given the short duration of our intervention, it is recommended that further longitudinal studies be performed on larger cohorts of patients in different geographical regions.
