Background: Mortality in critically ill patients with coronavirus disease 2019 (COVID‐19) is high, therefore, it is essential to evaluate the independent effect of new‐onset atrial fibrillation (NOAF) on mortality in patients with COVID‐19. We aimed to determine the incidence, risk factors, and outcomes of NOAF in a cohort of critically ill patients with COVID‐19.Methods: We conducted a retrospective study on patients admitted to the intensive care unit (ICU) with a diagnosis of COVID‐19. NOAF was defined as atrial fibrillation that was detected after diagnosis of COVID‐19 without a prior history. The primary outcome of the study was the effect of NOAF on mortality in critically ill COVID‐19 patients.Results: NOAF incidence was 14.9% (n = 37), and 78% of patients (n = 29) were men in NOAF positive group. Median age of the NOAF group was 79.0 (interquartile range, 71.5‐84.0). Hospital mortality was higher in the NOAF group (87% vs 67%, respectively, P = .019). However, in multivariate analysis, NOAF was not an independent risk factor for hospital mortality (OR 1.42, 95% CI 0.40‐5.09, P = .582).Conclusions: The incidence of NOAF was 14.9% in critically ill COVID‐19 patients. Hospital mortality was higher in the NOAF group. However, NOAF was not an independent risk factor for hospital mortality in patients with COVID‐19.

In this retrospective cohort study, we aimed to evaluate the incidence, risk factors and outcomes of amikacin-induced acute kidney injury (AKI) in critically ill patients with sepsis. A total of 311 patients were included in the study. Of them, 83 (26.7%) had amikacin-induced AKI. In model 1, the multivariable analysis demonstrated concurrent use of colistin (OR 25.51, 95%CI 6.99-93.05, p< 0.001), presence of septic shock during amikacin treatment (OR 4.22, 95%CI 1.76-10.11, p=0.001), and Charlson Comorbidity Index (OR 1.14, 95%CI 1.02-1.28, p=0.025) as factors independently associated with an increased risk of amikacin-induced AKI. In model 2, the multivariable analysis demonstrated concurrent use of at least one nephrotoxic agent (OR 1.95, 95%CI 1.10-3.45; p=0.022), presence of septic shock during amikacin treatment (OR 3.48, 95%CI 1.61-7.53; p=0.002), and Charlson Comorbidity Index (OR 1.12, 95%CI 1.01-1.26; p=0.037) as factors independently associated with an increased risk of amikacin-induced AKI. In conclusion, before amikacin administration, the risk of AKI should be considered, especially in patients with multiple complicated comorbid diseases, septic shock, and those receiving colistin therapy.

Background: The prediction of high-flow nasal oxygen (HFNO) failure in patients with coronavirus disease-2019 (COVID-19) having acute respiratory failure (ARF) may prevent delayed intubation and decrease mortality. Aims: To define the related risk factors to HFNO failure and hospital mortality Study Design: Retrospective cohort study. Methods: To this study. 85 critically ill patients (>= 18 years) with COVID- I 9 related acute kidney injury who were treated with HFNO were enrolled. Treatment success was defined as the de-escalation of the oxygenation support to the conventional oxygen therapies. HFNO therapy failure was determined as the need for invasive mechanical ventilation or death. The patients were divided into HFNO-failure (HFNO-F) and HFNO-success (HFNO-S) groups. Electronic medical records and laboratory data were screened for all patients. Respiratory rate oxygenation (ROX) index on the first hour and chest computed tomography (CT) severity score were calculated. Factors related to HFNO therapy failure and mortality were defined. Results: This study assessed 85 patients (median age 67 years, 69.4% male) who were divided into two groups as HFNO success (n = 33) and HFNO failure (n = 52). The respiratory rate oxygenation (ROX) was measured at I hour and the computed tomography (CT) score indicated HFNO failure and intubation, with an area under the receiver operating characteristic of 0.695 for the ROX index and 0.628 for the CT score. A ROX index of 15 in the first hour of therapy were the predictors of HFNO failure and intubation. Age. Acute Physiology and Chronic Health Evaluation II score, arterial blood gas findings "(i.e., partial pressure of oxygen [PaO2]. PaO2 [fraction of inspired oxygenYSO(2) [oxygen saturation] ratio)", and D-dimer levels were also associated with HFNO failure; however. based on logistic regression analysis, a calculated ROX on the first hour of therapy of 15 (OR = 2.83, 95% CI = 1.01-7.88, P = 0.001) were the only independent risk factors. In logistic regression analysis, a ROX calculated on the first hour of therapy of 15 (OR 2.83. 95% CI = 1.01-7.88, P = <0.001) were the independent risk factors for the HFNO failure. The intensive care unit and hospital mortality rates were 80.2% and 82.7%, respectively. in the HFNO failure group. Conclusion: The early prediction of HFNO therapy failure is essential considering the high mortality rate in patients with HFNO therapy failure. Using the ROX index and the chest CT severity score combined with the other clinical parameters may reduce mortality. Additionally multi-centre observational studies are needed to define the predictive value of ROX and chest CT score not only for COVID-19 but also other causes of ARF.

The first case of coronavirus disease 2019 (COVID-19) was defined as unexplained pneumonia on December 8, 2019, and then it rapidly caused a pandemic and affected transplantation rates negatively. Organ donation processes got more complex because the exclusion of the disease in a short period became more difficult than normal. The exclusion of the disease is vital not only for recipients but also for the medical staff, transplantation teams, and intensive care professionals to reduce the transmission risk. The main steps for diagnosis of COVID-19 are investigation of symptoms, recollection of travel and physical contact history, and testing using the real time polymerase chain reaction (RT-PCR) test. Although it has limitations such as false negative results, RT-PCR is the most accurate method to detect COVID-19, and it is mandatory before donation processes in many countries. In this case report, we aim to share our experience about the first organ donation during the COVID-19 pandemic in Turkey.
