The aim of this study was to examine differences in organisational characteristics, work characteristics and psychological work reactions, and to investigate relationships between these variables in intensive care units (ICUs) and non-ICUs. Questionnaires were distributed to intensive care (n = 184) and non-intensive care nurses (n = 927) working in 15 general hospitals in the Netherlands. MANOVA showed that ICU nurses reported significantly higher uncertainty, higher complexity, and higher decision authority than non-ICU nurses. Emotional exhaustion was significantly lower among ICU nurses. Regarding the pattern of relationships, the LISREL-analyses revealed that the indirect proposed pattern of relationships was invariant across the two samples, which means a validation of our research model.

Hepatic gas gangrene (HGG) is a rare but life-threatening condition typically caused by anaerobic bacteria such as Clostridium perfringens, though Gram-negative bacteria like Escherichia coli and Klebsiella species have also been implicated. Traditionally diagnosed via computed tomography (CT), point-of-care ultrasound (POCUS) has emerged as a valuable tool in critical care settings for its non-invasive, bedside utility. We report the case of a 51-year-old female with choledochal syndrome secondary to cholangiocarcinoma who developed HGG following left extended hepatectomy and biliary reconstruction.

The use of extracorporeal membrane oxygenation (ECMO) in surgery is expanding as the medical community started adopting it, with good results, for procedures with high risk of respiratory and hemodynamic instability. This technique provided the possibility to reduce the number of patients previously considered inoperable because of these limitations. Thymic epithelial tumors (TETs) are rare neoplastic mediastinal lesions, with a reported incidence of 0.

Introduction: The present study aimed to explore the epidemiologic threats and factors associated with the coronavirus disease 2019 (COVID-19)-associated mucormycosis (CAM) epidemic that emerged in Egypt during the second COVID-19 wave. The study also aimed to explore the diagnostic features and the role of surgical interventions of CAM on the outcome of the disease in a central referral hospital.
Methodology: The study included 64 CAM patients from a referral hospital for CAM and a similar number of matched controls from COVID-19 patients who did not develop CAM.

Introduction: This study investigated the role of fibroblast growth factor 23 (FGF23)/Klotho in the mortality of patients hospitalized with coronavirus disease 2019 (COVID-19), excluding those with chronic kidney disease (CKD).
Methodology: A prospective cross-sectional study was conducted from April 2021 to May 2022. Patients who tested positive for COVID-19 via polymerase chain reaction and were hospitalized, were classified into two groups (survivors and non-survivors) at the end of their hospital follow-up.
