Background Increasing workloads and psychological pressure have led to fatigue among healthcare workers during the COVID‐19 pandemic. Increasing stress and social isolation can also lead to sleep problems. The purpose of this study was to evaluate sleep quality and related factors among healthcare workers during the COVID‐19 pandemic in Turkey. Methods The data in this cross‐sectional study were collected using an online questionnaire. This included sociodemographic data, the Multidimensional Scale of Perceived Social Support, the National Stressful Events Survey PTSD Short Scale and the Pittsburgh Sleep Quality Index. Results Two hundred seventy‐eight physicians, 104 nurses and 52 dentists were enrolled. The total prevalence of poor sleep quality was 56.7%. The prevalence of poor sleep quality was 67.3% in nurses, 55.4% in physicians and 42.3% in dentists. Poor sleep quality was more prevalent among women, nurses, hospital workers, frontline workers, individuals with <5 years of work experience, those with low social support and individuals with increased traumatic stress levels. High levels of social support and family social support were identified as protective factors against poor sleep quality. Multivariate regression analyses showed that poor sleep quality was significantly associated with working in hospitals and high traumatic stress levels during the COVID‐19 pandemic. Conclusions Poor sleep quality was common among healthcare workers during the COVID‐19 pandemic. Working in hospitals and high traumatic stress levels were identified as factors associated with poor sleep quality.

Objective: The aim of the study was to analyze the relationship between smoking status and exhaled carbon monoxide (E-CO) levels, quality of life, and disease characteristics in patients with inflammatory bowel disease. Methods: The demographic and disease characteristics and smoking status of 121 patients with inflammatory bowel disease who presented our hospital between 01.12.2020 and 01.03.2021 were investigated. After the first follow-up, the E-CO levels of these participants were measured every four consecutive weeks. The mean of these E-CO readings was accepted as the main E-CO value. After one month after their first application SF-36 Quality of Life Scale was applied. The relationship between these variables was investigated. Results: The mean age of the participants was 42.06±14.9 years, and 36.3% were active smokers. While patients with Crohn’s disease (CD) exhibited a higher smoking rate, smokers with ulcerative colitis (UC) registered significantly higher mean CO ppm readings (p
