Objectives: The aim was to investigate the outcome MODS/MOF in critically ill patients with regard to early hepatic dysfunction.
Methods: Thirty adult polytrauma patients admitted to the ICU, with ISS >or=16 were prospectively investigated. Real-time liver function was assessed using the MEGX test and arterial ketone body ratio (AKBR) 12-24 h after admittance to ICU, and on days 3, 5, 8, 12.
Results: Six patients (19%) died between days 4 and 29. Non-survivors were older (64.2 vs. 31.5 years), had a significantly higher ISS (40.5 vs. 30; p=0.002) and MODS score (9.5 vs. 5; p=0.001) on admittance to the ICU than survivors. On day 3 MEGX values (31 vs. 71.3 microg/L; p=0.001) and the AKBRs (0.6 vs. 1.3; p=0.001) were significantly lower in non-survivors than in survivors whereas IL-6 levels were significantly higher in the former group (519 vs. 61 microg/L; p=0.05).
Conclusions: The MEGX test and AKBR are sensitive early indicators of hepatic dysfunction in severely injured polytrauma patients at risk for developing MODS/MOF.

Cancer is a fatal disease with a high global prevalence and is associated with an increased incidence of metabolic disorders. This study aimed to develop a novel metabolic prognostic system to evaluate the overall metabolic disorder burden in cancer patients and its relationship with their prognosis. The patients in this study were enrolled from the Investigation on Nutrition Status and Clinical Outcome of Common Cancers (INSCOC) project.

Aims: Research on family functioning in psychosis has typically focused on specific family-related factors and their impact on symptomatology, finding strong associations between high expressed emotion and poor outcomes, especially in those with long-term illness. The objective of this review is to examine the impact of a broad range of family-related factors and their relationship with clinical, social, occupational and relational outcomes in first-episode psychosis (FEP).
Method: A systematic search of databases PsycInfo, Pubmed, Embase and CINHAL between 1990 and August 2023 was completed.

Background: The incidence, mortality, and readmission rates for acute heart failure (AHF) are high, and the in-hospital mortality for AHF patients in the intensive care unit (ICU) is higher. However, there is currently no method to accurately predict the mortality of AHF patients.
Methods: The Medical Information Mart for Intensive Care Ⅳ (MIMIC-Ⅳ) database was used to perform a retrospective study.
Nasal myiasis: an infrequent cause of sinusitis in a critical care patient.
BMJ Case Rep

Critical Care Department, Finis Terrae University Faculty of Medicine, Santiago, Chile.
A patient in his 70s, admitted to the cardiac intensive care unit with cardiogenic shock, unexpectedly presented with nasal myiasis during a workup for persistently elevated inflammatory markers. CT scans revealed sinusitis and bronchial secretions, while bronchoscopy identified mucus with positive pathogen testing. Nasal endoscopy was crucial in diagnosing myiasis, and immediate mechanical removal of larvae was performed.
