Risk factors for sepsis are multiple comorbidities, poor nutrition status, and limited mobility. The primary purpose the study was determine whether ambulation ability with albumin C-reactive protein predictive 28-day mortality elderly patients sepsis. Methods This retrospective observational using multicentre-based registry between November 2016 February 2017. inclusion criteria were...

The United Kingdom guideline for acute paracetamol overdose has recommended the use of '100-treatment line'. Emergency medical centers in some developing countries lack resources timely reporting concentrations, hence treatment depends on reported dose. This study aimed to examine whether using an dose is safe predict concentration above 100-line.Data were retrieved from two emergency retrospectively, between 2010 and 2017. inclusion criteria single overdose, presentation within 15 h, age ≥...

Background. This study aimed at investigating whether the length of stay (LOS) in emergency department (ED) is associated with mortality elderly patients infections admitted to intensive care unit (ICU). Delayed admission ICU may be adverse clinical outcomes infections. Methods. was a retrospective conducted subjects over 65 years age from 5 EDs. We recorded demographic data, findings, initial laboratory results, and ED LOS. Outcomes were all-cause in-hospital hospital A multivariable...

Purpose: In 2012, a revised guideline for acute acetaminophen overdose was proposed in the UK, recommending that treatment threshold should be lowered to 100 mcg/ml at 4 hours after ingestion without risk stratification of hepatotoxicity. However, poison centers some developing countries do not have laboratory resources provide serum drug levels time. The primary aim study is evaluate cut-off value reported dose per kilogram determine when N-acetylcysteine warranted under guideline. Methods:...

Purpose: The Prescott nomogram has been utilized to forecast hepatotoxicity from acute acetaminophen poisoning. In developing countries, emergency medical centers lack the resources report concentrations; thus, commencement and cessation of treatment are based on reported dose. This study investigated risk factors that can predict detection after 15 hours for safe termination.Methods: Data were collected an urban center 2010 2020. included patients ≥14 years age with poisoning within hours....

Purpose We aimed to identify the factors associated with repeated febrile seizures (RFS), defined as recurrent during same illness. Methods reviewed medical records of children seizure who visited 4 academic emergency departments from October 2016 through September 2018. Differences were identified in variables regarding clinical and laboratory characteristics between without RFS. The RFS was primary outcome. Logistic regression conducted occurrence Results Among 1,551 children, 922 included...
