    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<.001), lactate level >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/FiO(2) 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.

    Evaluation of whole blood thiamine pyrophosphate concentrations in critically ill patients receiving chronic diuretic therapy prior to admission to Turkish intensive care units: A pragmatic, multicenter, prospective study
    (W B Saunders Co-Elsevier Inc, 2023) Gundogan, Kursat; Sahin, Gulsah G.; Ergul, Serap S.; Ozer, Nurhayat T.; Temel, Sahin; Akbas, Turkay; Ercan, Talha
    Background/Objectives: Thiamine plays a pivotal role in energy metabolism. The aim of the study was to deter-mine serial whole blood TPP concentrations in critically ill patients receiving chronic diuretic treatment before ICU admission and to correlate TPP levels with clinically determined serum phosphorus concentrations.Subjects/Methods: This observational study was performed in 15 medical ICUs. Serial whole blood TPP concen-trations were measured by HPLC at baseline and at days 2, 5 and 10 after ICU admission. Results: A total of 221 participants were included. Of these, 18% demonstrated low TPP concentrations upon admission to the ICU, while 26% of participants demonstrated low levels at some point during the 10-day study period. Hypophosphatemia was detected in 30% of participants at some point during the 10-day period of observation. TPP levels were significantly and positively correlated with serum phosphorus levels at each time point (P < 0.05 for all).Conclusions: Our results show that 18% of these critically ill patients exhibited low whole blood TPP concen-trations on ICU admission and 26% had low levels during the initial 10 ICU days, respectively. The modest correlation between TPP and phosphorus concentrations suggests a possible association due to a refeeding effect in ICU patients requiring chronic diuretic therapy.
