Background: -1-Acid glycoprotein (AGP) is an acute-phase protein that plays a role in first-line defense against infection and is therefore elevated in sepsis. We tested the hypothesis that AGP levels increase initially in sepsis and decrease after antimicrobial therapy and that these levels may predict treatment outcomes.
Methods: AGP, biomarkers widely used in clinical practice, and maximum 24-h acute physiology and chronic health evaluation (APACHE)-II scores upon emergency department (ED) admission were prospectively evaluated and compared. We further examined changes in AGP concentrations 1, 4, and 7 days after admission and determined the value of AGP that may be used to accurately and reliably predict the prognosis in patients with sepsis.
Results: Mechanical ventilation, white blood cell (WBC) counts, C-reactive protein (CRP) and lactate levels, maximum 24-h APACHE-II scores, and AGP concentrations were significantly higher upon admission in patients with sepsis who died. AGP and lactate concentrations were also significantly higher in non-survivors than in survivors on days 1, 4, and 7. As indicated by the stepwise logistic regression model analysis and area under the curve analysis, AGP was the best prognostic indicator, and the cut-off value for predicting fatality was 1307 g/mL, and any increase 1-ng/mL in AGP concentration would increase the fatality rate by 0.5%.
Conclusion: Based on our observations, AGP may be a good prognostic predictor in patients with sepsis. In addition, serial AGP levels meet the requirements for predicting outcomes in patients with sepsis.

Review of Childhood Mortality Pattern at the Paediatric Unit of a Teaching Hospital in Nigeria.

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.
Preoperative myosteatosis and perioperative serum chloride levels predict 180 day major complications after radical cystectomy.

This study aimed to investigate the role of myosteatosis, sarcopenia, and perioperative serum biomarkers as independent predictors of major complications within 180 days following radical cystectomy (RC) for muscle-invasive bladder cancer (MIBC). We retrospectively analyzed of 127 MIBC patients who underwent RC between 2013 and 2023 at a single institution. Preoperative body composition was assessed using CT scans at the L3 vertebral level to measure psoas muscle density (PMD), skeletal muscle density (SMD), axial muscle density (AMD), and muscle indices.
