Background: Vaccines against coronavirus disease-19 (COVID-19) have been effective in preventing symptomatic diseases, hospitalizations, and intensive care unit (ICU) admissions. However, data regarding the effectiveness of COVID-19 vaccines in reducing mortality among critically ill patients with COVID-19 remains unclear.

Aims: To determine the vaccination status and investigate the impact of the COVID-19 vaccine on the 28-day mortality in critically ill patients with COVID-19.

Background: We evaluated the effect of early awake prone position administration on oxygenation and intubation requirements and short-term mortality in patients with acute respiratory failure due to coronavirus disease 2019 (COVID-19) pneumonia.

Methods: This is an observational-cohort study. Patients receiving mask oxygen therapy in our intensive care units because of acute respiratory failure due to COVID-19 pneumonia were included.

Background: In Covid-19 pneumonia, high mortality rates reported in intubated patients have raised non-invasive methods of respiratory support.

Objective: We aimed to evaluate the impact of HFNC application on intubation requirement, intensive care length of stay, and short-term mortality in patients with COVID-19 pneumonia.

Material-method: Patients receiving oxygen by reservoir mask or HFNC therapy in our intensive care units due to COVID-19 pneumonia were included in the study.

Introduction: The Clinical Pulmonary Infection Score (CPIS) based on chest X-ray has been developed to facilitate clinical diagnosis of ventilator-associated pneumonia (VAP); however, this scoring system has a low diagnostic performance. We developed the Lung Ultrasound and Pentraxin-3 Pulmonary Infection Score (LUPPIS) for early diagnosis of VAP and evaluated the performance of this new scoring system.

Material And Methods: In a prospective study of 78 patients with suspected VAP, we assessed the detection accuracy of LUPPIS for pneumonia in adult patients.

Objective: Mushroom poisonings can lead to life-threatening organ dysfunctions and neurotoxicity-related encephalopathy. This study aimed to detect increased intracranial pressure by measuring optic nerve sheath diameter (ONSD) ultrasonographically and to determine its association with clinical and laboratory parameters.

Methods: In this prospective case-control study, we evaluated the patients aged above 18 years who presented to the emergency department with mushroom poisoning.

Background: Intra-abdominal hypertension (IAH) is a frequent cause of acute kidney injury (AKI) among critically ill patients who have risk factors. This study aimed to determine the relation between Abdominal Perfusion Pressure (APP) and AKI showed by the Doppler-based renal resistive index (RRI).

Methods: In this study, 38 patients older than 18 years old who received mechanical ventilation and had risk factors for the development of IAH were prospectively studied.

Objective: The identification of bacteraemia in patients with suspected sepsis is crucial for survival. A cheap, fast and reliable biomarker, which can predict the causative pathogen group, may be useful to confirm or exclude the presence of bacteraemia. This study aimed to evaluate the relationship between procalcitonin (PCT) and the causative pathogen in intensive care patients with sepsis and bacteraemia.

Aims: This experimental study was designed to investigate the effects of 10weeks genistein administration on oxidative stress and inflammation in serum and liver of rats fed with fructose.

Main Methods: 6-8weeks old, 40 male Sprague-Dawley rats were included. Group 1 (control) was fed with standard chow food and 100μl/kg/day/rat dimethyl sulfoxide (DMSO) administered subcutaneously; group 2 (genistein) with standard chow food and 0.

Aim: Cardiovascular diseases are among the leading causes of morbidity and mortality in developed countries. Metabolic syndrome is a common clinical presentation posing significant risk in cardiovascular diseases. This study investigated the correlation between the number of diagnostic criteria and serum adiponectin, leptin, resistin, TNF-alpha, EGFR levels and abdominal adipose tissue in the individuals with metabolic syndrome.
