Attitudes toward learning communication skills among Iranian medical students.

BACKGROUND: Attitudes determine behavior, and alterations in attitude may result in behavioral changes. Medical students would benefit from learning communication skills. This study aimed to determine the attitude of medical students toward the importance of learning communication skills and the training courses and their role in contributing. METHODS: In this cross-sectional study, 442 medical students from three different levels of medical training were enrolled. Students in the first 4 years of the medical program were classified as basic sciences and physiopathology students, those in the fifth and sixth years were classified as clerkship students, and those in the last three terms of medical training were classified as interns. The attitude among these three groups was assessed by the Communication Skills Attitude Scale (CSAS) questionnaire, and the contributing factors were determined. RESULTS: The mean total points for attitude in positive and negative aspects were 50.7 and 30.9, respectively showing a positive attitude toward communication skills among medical students. The median scores of the scales Important in Medical Content, Excuse, Learning, and Overconfidence varied significantly from highest to lowest, respectively. Gender, educational level, ethnic origin, language, family burden, paternal literacy, history of presence in communication skills courses, self-report from communication skills, and need to further learning in this era showed significant association with attitude (P < 0.05). CONCLUSIONS: It may be concluded that generally, medical students have a positive attitude toward communication skills, and this perspective is a multi-factorial entity that programming according to the various related factors would help to attainment of additional communication capabilities among medical students.

The impact of HIV on the risk of COVID-19 death among hospitalized patients.

BACKGROUND: Little is known about the association between Human Immunodeficiency Virus (HIV) infection and risk of death among hospitalized COVID-19 patients. We aimed to investigate this association using a multicenter study. MATERIAL AND METHODS: This multicenter study was conducted using the registry database of Coronavirus Control Operations Headquarter from March 21, 2021 to January 18, 2020 in the province of Tehran, Iran. The interest outcome was COVID-19 death among hospitalized patients living with and without HIV. The Cox regression models with robust standard error were used to estimate the association between HIV infection and risk of COVID-19 death. The subgroup and interaction analysis were also performed in this study. RESULTS: 326052 patients with COVID-19 were included in the study, of whom 127 (0.04%) were living with HIV. COVID-19 patients with HIV were more likely to be female, older, and to have symptoms such as fever, muscular pain, dyspnea and cough. The death proportion due to COVID-19 was 18 (14.17%) and 21595 (6.63%) among HIV and non-HIV patients, respectively. Patients living with HIV had lower mean survival time compared to those without HIV (26.49 vs. 15.31 days, P-value = 0.047). Crude risk of COVID-19 death was higher among HIV patients than in non-HIV group (hazard ratio[HR]: 1.60, 1.08-2.37). Compared to those without HIV, higher risk of COVID-19 death was observed among patients with HIV after adjusting for sex (1.60, 1.08-2.36), comorbidities (1.49, 1.01-2.19), cancer (1.59, 1.08-2.33), and PO2 (1.68, 1.12-2.50). However, the risk of COVID-19 death was similar in patients with and without HIV after adjusting for age (1.46, 0.98-2.16) and ward (1.30, 0.89-1.89). CONCLUSION: We found no strong evidence of association between HIV infection and higher risk of COVID-19 death among hospitalized patients. To determine the true impact of HIV on the risk of COVID-19 death, factors such as age, comorbidities, hospital ward, viral load, CD4 count, and antiretroviral treatment should be considered.

Investigating air quality status and air pollutant trends over the Metropolitan Area of Tehran, Iran over the past decade between 2005 and 2014.

Studies on the trend of air pollution in Tehran, Iran, as one of the most polluted metropolis in the world are scant, and today Tehran is known for its high levels of air pollutants. In this study, the trend of air pollution concentration was evaluated over the past 10 years (2004-2015). The data were collected from 22 stations of the Air Quality Control Company. Daily concentrations of CO, NO2, SO2, O3, PM10 were analyzed using SPSS 16 based on the statistical method, repeated measures, and intra-group test to determine the pattern of each pollutant changes. As a result of the 22 air pollution monitoring stations, NO2 and SO2 concentrations have been increasing over the period of 10 years. The highest anomaly is related to SO2. The CO concentrations represent a descending pattern over the period, although there was a slight increase in 2013 and 2014. The O3 concentrations declined in the following years. The average concentration of PM10 has been rising during the period. Also we evaluated changes of each pollutant in different months and calculated the number of clean, healthy, unhealthy days for sensitive, unhealthy, very unhealthy, and dangerous groups. The study findings illustrated the necessity for larger investment in air pollution abatement. Overall, trends have been progressed to worsening, the number of healthy days has been declined and the number of unhealthy days has been increased in recent years.
