Relationships between internet addiction, smartphone addiction, sleep quality, and academic performance among high-school students.

OBJECTIVE: In this study, we aimed to evaluate the relationships between Internet addiction, smartphone addiction, sleep quality, and academic success. METHODS: In this cross-sectional study, high-school students were surveyed to evaluate sleep quality, Internet addiction, and smartphone addiction. Students were queried about their demographics, and grade averages from the previous term were taken as an indicator of academic success. RESULTS: A total of 1,959 students were enrolled in this study, with 1,034 (52.8%) girls and 925 (47.2%) boys, and the median age of the participants was 16 (13-21) years. Multivariate analyses found that poor sleep quality in students who did not have breakfast before going to school was 1.58 times higher than those who did (p<0.001). Students who stayed in a dormitory had 1.79 times more poor sleep quality than those who stayed with their family, and a one-unit increase in the total score of the Young's Internet Addiction Test short form resulted in a 1.08-fold increase (both, p<0.001). CONCLUSION: Our study has shown that students' sleep quality was predicted to be lower if they stayed in a dormitory and skipped breakfast. In addition, Internet and smartphone addictions have a negative effect on sleep quality and academic performance.

Tocilizumab treatment in COVID-19: A prognostic study using propensity score matching.

BACKGROUND: The potential role of interleukin-6 (IL-6) in coronavirus disease 2019 (COVID-19) pneumonia provides the rationale for investigating IL-6 signaling inhibitors. OBJECTIVES: To evaluate and report treatment responses to tocilizumab (TCZ) in COVID-19 patients and compare mortality outcomes with those of standard care. MATERIAL AND METHODS: Patients hospitalized with a severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, diagnosed with reverse transcription polymerase chain reaction (RT-PCR) between March 2020 and April 2021, were enrolled in this single-center retrospective cohort study. Propensity score matching was performed in order to reduce confounding effects secondary to imbalances in receiving TCZ treatment. RESULTS: A total of 364 patients were included in this study. Two hundred thirty-six patients received standard care, while 128 patients were treated with TCZ in addition to standard care (26 (20.3%) patients received a dose of 400 mg intravenously once, while 102 (79.7%) patients received a total dose of 800 mg intravenously). In the propensity score-matched population, less noninvasive mechanical ventilation (p = 0.041) and mechanical ventilation support (p = 0.015), and fewer deaths (p = 0.008) were observed among the TCZ-treated patients. The multivariate adjusted Cox regression model showed a significantly higher survival rate among TCZ patients compared to controls (hazard ratio (HR): 0.157, 95% confidence interval (95% CI): 0.026-0.951; p = 0.044). The hazard ratio for mortality in the TCZ group was 0.098 (95% CI: 0.030-0.318; p = 0.0001 using log-rank test). CONCLUSIONS: This study determined that TCZ treatment in COVID-19 patients was associated with better survival, reduced need for mechanical ventilation and reduced hospital-associated mortality.

Relationship of pneumococcal and influenza vaccination frequency with health literacy in the rural population in Turkey.

INTRODUCTION: Vaccines have been shown to prevent illness, disability and death from vaccine-preventable diseases. The purpose of our study was to analyze the influenza and pneumococcal vaccination status of patients, the factors that influence the uptake of influenza/pneumococcal vaccination and the effects of health literacy (HL) on vaccination. MATERIALS AND METHODS: In this cross-sectional study, demographic characteristics, comorbid diseases and the pneumococcal and influenza vaccination status in previous years were recorded for each patient. The Turkish version of the European Health Literacy Survey Questionnaire (HLS-EU-Q47) was used to assess HL. RESULTS: A total of 350 patients were enrolled in the study. A total of 6.3% of patients had received both vaccines. 20% of subjects were vaccinated with influenza vaccine and 11.1% of the subjects were vaccinated with pneumococcal vaccine. Overall HL was insufficient for 70.9%, problematic for 20.6%, sufficient for 7.1% and excellent for 14.2% of patients. Patients who had pneumococcal and influenza vaccination had higher disease prevention HL scores (p = 0.013, p = 0.001; respectively). DISCUSSION: An insufficient HL level was found to be much higher than previous studies. It was observed that an increase in disease prevention HL was associated with a rise in the rate of pneumococcal and influenza vaccination.
