Objective: To identify the clinical characteristics and outcomes of hospital-acquired SARS-CoV-2 infection during the vaccination period nationwide in Turkey. Methods: COVID-19 patients followed in the pandemic services across Turkey between January 1, 2021, and March 31, 2022 were investigated retrospectively. Nosocomial COVID-19 was defined as a patient neither diagnosed with COVID-19 nor suspected COVID-19 at the hospital admission and was confirmed COVID-19 >= 5 days after hospital admission. The primary outcome of this study was in-hospital mortality; demographic features and vaccination status was compared between survivors and non survivors. Results: During the study period, 15 573 COVID-19 patients were followed in 18 centers and 543 (3.5%) patients were nosocomial COVID-19. Most patients with nosocomial COVID-19 (80.4%) were transferred from medical wards. 162 (29.8%) of the patients with nosocomial COVID-19 admitted to the intensive care unit due to disease severity and 138 (25.4%) of the patients died during hospital stay. Advanced age (>= 65 years) and number of comorbid diseases (>= 2) was found to be associated with mortality in nosocomial COVID-19 (OR 1.74, 95% CI 1.11-2.74 and OR 1.60, 95% CI 1.02-2.56, respectively). Vaccination was associated with survival in nosocomial COVID-19 (OR 0.25, 95% CI0.16-0.38). Conclusions: Patients with nosocomial COVID-19 had increased admission to intensive care units and higher mortality rate. Vaccination can decrease the in-hospital mortality rate.

Cancer patients often face malnutrition, which negatively affects their response to cancer treatment. This study aims to analyze the effects of the COVID-19 pandemic on nutritional status and anxiety in cancer patients with different types and stages of cancer. This is a cross-sectional cohort study that includes 1,252 patients with varying cancer types from 17 radiation oncology centers. The nutritional risk scores (NRS-2002) and coronavirus anxiety scale (CAS) scores of all patients were measured. NRS-2002 >= 3 and CAS >= 5 were accepted as values at risk. Of all patients, 15.3% had NRS-2002 >= 3. Breast cancer was the most prevalent cancer type (24.5%) with the lowest risk of nutrition (4.9%, p < 0.001). Nutritional risk was significantly higher in patients with gastrointestinal cancer, head and neck cancer, and lung cancer (p < 0.005) and in patients with stage IV disease (p < 0.001). High anxiety levels (CAS >= 5) were significantly related to voluntary avoidance and clinical postponement of hospital visits due to the pandemic (p < 0.001), while clinical postponement was particularly frequent among patients with NRS-2002 < 3 (p = 0.0021). Fear and anxiety in cancer patients with COVID-19 cause hesitations in visiting hospitals, leading to disrupted primary and nutritional treatments. Thus, nutritional monitoring and treatment monitoring of cancer patients are crucial during and after radiotherapy.
