Prognostic Value of Renal Dysfunction Indicators in Normotensive Patients With Acute Pulmonary Embolism

Introduction: Glomerular filtration rate (GFR) and blood urea nitrogen (BUN) are important prognostic indicators for cardiovascular disease. However, data on the relationship between renal dysfunction (RD) and prognosis in patients with acute pulmonary embolism (APE) are limited. The estimated-GFR (eGFR), based on the Modification of Diet in Renal Disease (MDRD) equation, has been suggested as a possible prognostic marker in patients with APE; however, at present, the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation is thought to be more accurate than the MDRD equation for the estimation of RD. Objective: We investigated whether eGFR(CKD-EPI) or BUN could predict adverse outcomes (AOs) better than eGFR(MDRD) in normotensive patients with APE. Methods: Ninety-nine normotensive patients with APE (aged 22-96, 56% male) were enrolled in the study retrospectively. Adverse outcomes were defined as the occurrence of any of the following: death, cardiopulmonary resuscitation, use of vasopressors, thrombolysis, or mechanical ventilation. Results: In univariate analyses, age, gender (male), heart rate (>110 bpm), serum creatinine, BUN, cardiac troponin (cTn) positivity, right ventricle-left ventricle ratio, eGFR(MDRD), and eGFR(CKD-EPI) were found to be significantly different between those with and without AOs. Comparing area under the curves for AO, we found statistically significant differences between eGFR(CKD-EPI) and eGFR(MDRD) (P = .01) but not between BUN and eGFR(CKD-EPI) or BUN and eGFR(MDRD). Furthermore, 30-day mortality was 36% versus 11% in cTn-positive patients with an eGFR(CKD-EPI) < and 60 mL/min, respectively. Conclusion: There is a close relationship between RD and APE prognosis. We conclude eGFR(CKD-EPI) is a potential prognostic marker for risk stratification in normotensive patients with APE

Clinical characteristics and outcomes of nosocomial COVID-19 in Turkey: A retrospective multicenter study

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% Cl 1.11-2.74 and OR 1.60, 95% Cl 1.02-2.56, respectively). Vaccination was associated with survival in nosocomial COVID-19 (OR 0.25, 95% Cl 0.16-0.38). 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

Clinical outcomes and independent risk factors for 90-day mortality in critically ill patients with respiratory failure infected with sars-cov-2: A multicenter study in turkish intensive care units

Background: There are limited data on the long-term outcomes of COVID-19 from different parts of the world. Aims: To determine risk factors of 90-day mortality in critically ill patients in Turkish intensive care units (ICUs), with respiratory failure. Study design: Retrospective, observational cohort. Methods: Patients with laboratory-confirmed COVID-19 and who had been followed up in the ICUs with respiratory failure for more than 24 hours were included in the study. Their demographics, clinical characteristics, laboratory variables, treatment protocols, and survival data were recorded. Results: A total of 421 patients were included. The median age was 67 (IQR: 57-76) years, and 251 patients (59.6%) were men. The 90-day mortality rate was 55.1%. The factors independently associated with 90-day mortality were invasive mechanical ventilation (IMV) (HR 4.09 [95% CI: [2.20-7.63], P 2 mmol/L (2.78 [1.93-4.01], P < .001), age ≥60 years (2.45 [1.48-4.06)], P < .001), cardiac arrhythmia during ICU stay (2.01 [1.27-3.20], P = .003), vasopressor treatment (1.94 [1.32-2.84], P = .001), positive fluid balance of ≥600 mL/day (1.68 [1.21-2.34], P = .002), PaO2 /FiO2 ratio of ≤150 mmHg (1.66 [1.18-2.32], P = .003), and ECOG score ≥1 (1.42 [1.00-2.02], P = .050). Conclusion: Long-term mortality was high in critically ill patients with COVID-19 hospitalized in intensive care units in Turkey. Invasive mechanical ventilation, lactate level, age, cardiac arrhythmia, vasopressor therapy, positive fluid balance, severe hypoxemia and ECOG score were the independent risk factors for 90-day mortality.
