Objectives We aimed to investigate the effects of the COVID-19 disease on kidney functions and early prognosis. Materials and Methods All cases were divided into those discharged and exitus cases. The patients were diagnosed with acute kidney injury (AKI) according to the KDIGO criteria. Results As a result of the ROC analysis, the patients with a creatinine value above 1.05 for day 1 and 0.975 for creatinine value on day 7 would be mortal (AUC values of 0.641 (0.569–0.714) and 0.757 (0.689–0.825), respectively). As a result of Univariate analysis; D-Dimer, Procalcitonin, BUN and creatinine values are risk factors and a one-unit increase in these values is 1.184; 1.105; It was determined that it would increase 1.024 and 1.304 times (p values 0.008; 0.007; <0.001; 0.002), respectively. Decreased in e-GFR value would increase the risk of death 1.026 (1/0.975) times (p<0.001). Conclusions We observed the high creatinine, D-dimer, procalcitonin, ferritin, and low e-GFR levels were risk factors for severity and mortality for COVID-19 disease. While physicians and all stakeholders focus on the prognosis and mortality of the disease of COVID-19 disease, it is necessary to be thorough about kidney involvement as much as respiratory system involvement.

ABSTRACT Purpose: Health workers have been greatly affected by the pandemic, both as a health worker and as a member of the society, and have gone out of their routine lifestyle and habits more than normal individuals. In the pandemic stage; intense, irregular and stressful work pace also disrupted the routine eating habits while increasing the need for nutrition. With this survey study, it is aimed to evaluate the nutritional habits, affecting factors and results of healthcare professionals during the Covid-19 pandemic stage. Materials and methods: For our study a questionnaire of 49 questions was prepared. It was continued between 01/06/2020 and 01/01/2021. Questionnaires were prepared on Google forms and sent to healthcare professionals via e-mail. Multiple-choice questions were asked about personal information such as the number of meals, whether they gained weight during the pandemic stage, foods believed to protect from Covid-19, nutritional supplements used during the pandemic period, and the reason for using supplements. The questions in the second category are; it mostly includes questions about changes in dietary and lifestyle of health workers during the pandemic period. It includes questions such as: ‘‘My meal count has increased’’, ‘‘My water consumption has increased’’, ‘‘My night eating behavior has improved’’, ‘‘My sleep pattern has been disrupted’’, ‘‘I gained weight during the pandemic’’, ‘‘I smoke more’’, ‘‘I drink more tea and coffee’’, ‘‘I try to exercise’’. The answers were obtained with a 3-point Likert scale (agree, undecided, disagree). Results: It was determined that health workers experienced weight gain during the pandemic stage. It was determined that the average weight and average BMI of health professionals showed a statistically significant increase (p

Abstract: Background: Sleep is one of the basic daily life activities that are important for a person with physical, mental, social, and intellectual needs to be healthy both physically and mentally. Although many definitions are made, sleep; is a complex and physiological event affected by pathophysiological, physical, psychological, and environmental factors. Anesthesiologists often work in closed environments and with long working hours, which can cause severe, chronic sleep loss and sleep disruption. Sleeplessness and low sleep quality can cause decreased attention during the day, impaired judgment, and delays in decision-making. This study, it is aimed to determine the sleep quality of Anesthesiology and Reanimation specialists working in Turkey. Methods: The study included all anesthesiologists whose e-mail addresses were registered with the Turkish Society of Anesthesiology and Reanimation and who worked in Turkey. Survey questions, which the participants can answer electronically, were sent to the participant's e-mail addresses. To increase the number of participants, a reminder email was sent three weeks after the first email. The data were expressed as a number, percentage, mean, and standard deviation and the correlation between the parameters will be evaluated at a 95% confidence interval by performing Pearson correlation analysis; p< 0.05 was accepted as significant. Results: Due to seven people with sleep disorders being excluded from the study, 210 out of 217 people who answered the questionnaires sent by email to the anesthetists who are members of the Turkish Society of Anesthesiology and Reanimation were included in the study. Of the respondents who worked in the following fields: 30% (n = 63) State Hospital, 33.3% (n = 70) University Hospital, 17.1% (n = 36) Ministry of Health Affiliate Hospital, 19.5% (n = 41) Private Hospital, and 73.3% (n = 154) at the Operating Room, 10% (n = 21) at the Intensive Care, 15.2% (n = 32) at the Operating Room + Intensive Care, and 1.4% (n = 3) at other departments, 48.4% (n = 105) were male, 51.6% (n = 112) were female, with a mean age of 41.5±7.6 years. The average hourly shift for the participants, 61% of whom were on the night shift, was 50 hours per month, and 25% were working more than 45 hours per week (Table 1). Conclusion: The sleep quality of anesthesiologists is poor, which causes daytime dysfunction. It is thought that the reason for poor sleep quality, in general, is the adverse effects of their duties and responsibilities, working environment, and operating conditions on sleep quality.

Abstract: Backgraound: Optic nerve sheath diameter measurement is a non-invasive method that provides rapid results in intracranial pressure assessment. Our aim in this study is to investigate how spinal anesthesia and tourniquet use affect optic nerve sheath diameter values in total knee arthroplasty operations. Methods:30 cases were included in the study. After spinal anesthesia, the tourniquet cuff was inflated. Right and left optic nerve sheath diameter measurements were performed 5 times with ocular ultrasound before spinal anesthesia, after spinal anesthesia, at 10th minutes after tourniquet inflation, 30th minutes after tourniquet inflation, and after tourniquet was deflated. The measurements were recorded in centimeters. During the first 24 hours postoperatively, the patients were followed up for the headache and/or visual impairment. Results: A significant difference was found between optic nerve sheath diameter values before and after spinal anesthesia (p
