Background In recent years, the phenomena of access to the cell phone and addiction to the Internet have been developed among students due to their many applications and attractiveness. Therefore, the present study was conducted with the aim of evaluating general health status and also determining the predictive role of variables such as cell phone usage, sleep quality, internet addiction and social networks addiction in students. Methods This cross-sectional study was conducted on 321 students of Kermanshah University of Medical Sciences in an analytical approach. Data collection tools were: Goldberg’s General Health Questionnaire, Pittburgh Sleep Quality Index, Young Internet Addiction Test, Social Network Addiction Questionnaire, and Cell Phone Overuse Scale. Data analysis was done using SPSS version 21 and general linear model. Results Based on the results, the mean (SD) score of the general health was 21.27 (9.49). Variables of gender, sleep quality, and levels of cell phone usage were independent predictors of student’s health. Male students (β (95% CI) = − 0.28 (− 0.49 to − 0.01) and students with favorable sleep quality (β (95% CI) = − 0.22 (− 0.44 to − 0.02) had lower total health score than the reference category (female students and students with unfavorable sleep quality, respectively). In addition, students with cell phone overuse (β (95% CI) = 0.39 (0.08 to 0.69) had a higher general health score than the reference category (students with cell phone little use). In general, this group of students had lower general health status (Low or high scores of general health indicate a higher and lower general health status for subjects, respectively). Conclusion Variables of gender, sleep quality and cell phone use were the most important variables associating the general health of medical students.

Background: Pneumonia caused by the ventilator is the most common acquired infection in the intensive care unit, which increases the morbidity and mortality of the patients. Eucalyptus plant has antiseptic properties. Therefore, the present study investigates the effect of eucalyptus incense on prevention of pneumonia in patients with endotracheal tube in the intensive care unit. Methods: This clinical trial study was performed on 100 patients under ventilation in two intervention and control groups in Imam Reza Hospital, Kermanshah, Iran in 2018. The patients in the intervention group, Eucalyptus solution 2% and in the control group received 10 cc distilled water as an inhaler three times a day. The results of the two groups were compared to the incidence of pulmonary infections based on CPIS criteria and compared with SPSS version 19 software. Results: The incidence of late pneumonia was significantly lower in the intervention group (P=0.02). The onset of pneumonia significantly later in the intervention group than the control group (P=0.01). The prevalence of Klebsiella, Candida albicans, and Staphylococcus aureus was significantly decreased in the intervention group (P=0.02) (P=0.04) (P=0.01). Conclusion: The results of this study showed that eucalyptus inhalation is effective in reducing the incidence of pulmonary infection in patients under ventilation. It is recommended that these products be used to prevent pulmonary infections in these patients.
