Introduction: Early identification of sepsis significantly improves outcomes, suggesting a role for prehospital screening. An end-tidal carbon dioxide (ETCO) value ≤ 25 mmHg predicts mortality and severe sepsis when used as part of a prehospital screening tool. Recently, the Quick Sequential Organ Failure Assessment (qSOFA) score was also derived as a tool for predicting poor outcomes in potentially septic patients.
Methods: We conducted a retrospective cohort study among patients transported by emergency medical services to compare the use of ETCO ≤ 25 mmHg with qSOFA score of ≥ 2 as a predictor of mortality or diagnosis of severe sepsis in prehospital patients with suspected sepsis.
Results: By comparison of receiver operator characteristic curves, ETCO had a higher discriminatory power to predict mortality, sepsis, and severe sepsis than qSOFA.
Conclusion: Both non-invasive measures were easily obtainable by prehospital personnel, with ETCO performing slightly better as an outcome predictor.

Department of Paediatrics, Federal Teaching Hospital, Ido-Ekiti. Email: Tel: +2348035741951.
Background: The vital statistics in the third world countries are poor and have witnessed minimal improvement over the years with childhood mortality in Nigeria remaining one of the highest among the developing countries despite various child survival programmes. Child survival strategies can only be efficient if the major reasons for morbidity are known. The objective of this retrospective study was to review the patterns of childhood mortality at the emergency room of the Federal Teaching Hospital, Ido-Ekiti (FETHI).

Introduction: Since the dawn of the new millennium, Candida species have been increasingly implicated as a cause of both healthcare-associated as well as opportunistic yeast infections, due to the widespread use of indwelling medical devices, total parenteral nutrition, systemic corticosteroids, cytotoxic chemotherapy, and broad-spectrum antibiotics. Candida tropicalis is a pathogenic Candida species associated with considerable morbidity, mortality, and drug resistance issues on a global scale.

Introduction: Invasive candidiasis is an important cause of nosocomial infection and recent studies have shown an increase in the number of cases during the coronavirus disease 2019 (COVID-19) pandemic. The present study aimed to evaluate the epidemiology and incidence of invasive candidiasis before and during the COVID-19 pandemic at a reference tertiary hospital in Brazil.
Methodology: A retrospective observational study was performed with 148 patients infected with Candida spp.

Objective: Early diagnosis of intensive care unit-acquired weakness (ICUAW) is crucial for improving the outcomes of critically ill patients. Hence, this study was designed to identify predisposing factors for ICUAW and establish a predictive model for the early diagnosis of ICUAW.
Methods: This prospective observational multicenter study included septic patients from the comprehensive ICUs of West China Hospital of Sichuan University and 10 other hospitals between September and November 2023.
