Article Abstract
Purpose: The aim of the study was to determine whether distributions of tumor necrosis factor (TNF)-α(308), interleukin (IL)-10(1082), CD14(159), and IL-1ra gene intron 2 genotypes in critically ill patients are associated with outcome, underlying cause of sepsis, and type of microorganism.
Materials And Methods: Blood samples from 106 critically ill white patients were genotyped by method based on polymerase chain reaction for TNF-α(308), IL-10(1082), CD14(159), and IL-1ra gene intron 2.
Results: All patients with TNF-α(308)AA genotype survived; relative risk (RR) of death in patients with AG was 3.250 and with GG, 1.923 (P < .01). In patients with Gram-positive sepsis, IL-10(1082)AA and then AG genotypes were the most frequent ones (odds ratio [OR], 18.67 and 7.20, respectively; P < .01). When comparing IL-10(1082)AA with AG, RR of pancreatitis was 1.80 and OR was 3.40. When AA and GG were compared, RR was 7.33 and OR was 20.00. In patients with GG, RR of peritonitis was 4.07 and OR was 5.88 (P < .01). In patients with Gram-positive sepsis, CD14(159)CT was the most frequent one with OR of 5.25. Distribution of 6 IL-1ra gene intron 2 genotypes showed no significant association.
Conclusions: Distribution of TNF-α(308) genotypes is associated with outcome, IL-10(1082) with type of microorganism and underlying cause of sepsis, and CD14(159) with type of microorganism.

Objectives: The risk of major venous thromboembolism (VTE) among patients with COVID-19 is high but varies with disease severity. Estimate the incidence of lower extremity deep venous thrombosis (DVT) in critically ill hospitalized patients with COVID-19, validate the Wells score for DVT diagnosis, and determine patients' prognosis.
Methods: This was an observational follow-up study in the context of the diagnosis and prognosis of DVT.

Purpose: Metabolic syndrome (MetS) is linked to adverse outcomes in chronic diseases, but its impact on acute kidney injury (AKI) in elderly critically ill patients remains unclear. This study aimed to evaluate the association between MetS and 90-day mortality in this population.
Patients And Methods: A retrospective analysis included 774 elderly patients (≥65 years) with AKI admitted to the ICU from January 2022 to December 2023.

Background: Psychosocial disability (PSD) refers to the limitations experienced by persons with mental illness (PWMI) in interacting with their social environment. Persons with psychosocial disabilities (PPSD) face significant barriers to accessing sexual and reproductive health (SRH) services due to structural and institutional barriers. Despite commitments under the Convention on the Rights of Persons with Disabilities (CRPD), there are persistent rights violations and denial of PPSD to exercise their rights and access services related to SRH care.

Background: In critically ill patients with septic shock, adequate oxygenation is crucial and hypoxia should be avoided. However, hyperoxia has been linked to the formation of reactive oxygen species, inflammation, and vasoconstriction, which could potentially harm critically ill intensive care patients. Therefore, this study aimed to examine the association between oxygen exposure and mortality and to define optimal oxygen target ranges for this specific group of patients.

Introduction: The inappropriate use of antibiotics in intensive care units poses risks, such as increased infections caused by multidrug-resistant bacteria and adverse reactions. The World Health Organization's strategy, named Access, Watch, and Reserve, aims to mitigate these risks by categorizing antibiotics into these categories.
Objective: To characterize antibiotic consumption in the adult population of intensive care units during the first quarter of 2023.
