Article Synopsis
  • Glycemic variability (GV) is a common issue in critically ill patients, and this study explored its impact on 28-day mortality through a multicenter analysis involving 578 patients across five ICUs in Turkey.
  • The study tracked several glycemic parameters within the first 24 hours, finding significant differences in CV (coefficient of variation), SD (standard deviation), and MGD (maximal-minimal glucose difference) between survivors and non-survivors, with higher levels linked to increased mortality risk.
  • Results indicated that CV is an independent risk factor for mortality, with a strong correlation with MGD, suggesting that monitoring these glycemic metrics could be critical for predicting patient outcomes in intensive care settings.

Although the representation of women in palliative care has improved in recent years, gender inequality still exists in editorial leadership. This study aimed to characterize gender distribution in leadership positions on the editorial boards of palliative care journals. This cross-sectional study analyzed the gender composition of editorial boards for palliative care journals indexed in the Web of Science (WoS) and the factors that affect this composition.

There is no study that comprehensively evaluates data on the readability and quality of "palliative care" information provided by artificial intelligence (AI) chatbots ChatGPT®, Bard®, Gemini®, Copilot®, Perplexity®. Our study is an observational and cross-sectional original research study. In our study, AI chatbots ChatGPT®, Bard®, Gemini®, Copilot®, and Perplexity® were asked to present the answers of the 100 questions most frequently asked by patients about palliative care.

Objective: Pleural fluid pH measurement is recommended for tube thoracostomy decisions in complicated parapneumonic pleural effusions. However, pleural fluid pH may be affected by blood pH in critically ill patients with common systemic acid-base disorders. We aimed to investigate the use of pleural fluid lactate to distinguish culture-positive parapneumonic effusions from other pleural effusions.

Objective: Coronavirus disease 2019 (COVID-19) can cause acute respiratory distress syndrome (ARDS). Invasive mechanical ventilation (IMV) support and prone positioning are essential treatments for severe COVID-19 ARDS. We aimed to determine the combined effect of prone position and airway pressure release ventilation (APRV) modes on oxygen improvement in mechanically-ventilated patients with COVID-19.

Introduction: Colistin is considered as a last resort therapy for multidrug-resistant gram-negative organisms. It is widely used despite the significant risk of nephrotoxicity. Experimental studies showed the nephroprotective effect of dexmedetomidine, a sedative agent, against colistin toxicity.

Article Synopsis
  • Low serum magnesium levels are common in ICUs and may be linked to new-onset atrial fibrillation (NOAF), which is under-researched.
  • A study with 110 ICU patients found that those with NOAF had lower median magnesium levels and a higher rate of hypomagnesemia compared to a control group.
  • NOAF is associated with higher mortality in critically ill patients, with hypomagnesemia identified as an independent risk factor for developing NOAF and increased hospital mortality.

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.

Background: Acute kidney injury is strongly associated with mortality in critically ill patients with coronavirus disease 2019 (COVID-19); however, age-related risk factors for acute kidney injury are not clear yet. In this study, it was aimed to evaluate the effects of clinical factors on acute kidney injury development in an elderly COVID-19 patients.

Methods: Critically ill patients (≥65years) with COVID-19 admitted to the intensive care unit were included in the study.

Aim Of The Study: To investigate the disease-specific score and improve the existing scores to better determine the prognosis of patients after liver transplantation (LT). For this purpose, we evaluated the relationship of prognostic scores with 30-day mortality after LT. In addition, we planned to investigate whether the mean platelet volume/platelet count (MPR) would contribute to score improvement.

Objective: To evaluate the incidence of risk factors for postintubation hypotension in critically ill patients with COVID-19.

Methods: We conducted a retrospective study of 141 patients with COVID-19 who were intubated in the intensive care unit. Postintubation hypotension was defined as the need for any vasopressor dose at any time within the 60 minutes following intubation.

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.

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.

Article Synopsis
  • - The study investigated the independent risk factors for 28-day mortality in critically ill COVID-19 patients in intensive care, finding that factors like sepsis, acute kidney injury, and high chest CT scores significantly increase the risk.
  • - A total of 249 patients were analyzed, with a high 28-day mortality rate of 67.9%; deceased patients had a median age of 75 and were primarily male.
  • - The research highlights the importance of early detection of risk factors to potentially improve outcomes for COVID-19 patients in severe conditions.
