Sequential oxygenation index and organ dysfunction assessment within the first 3 days of mechanical ventilation predict the outcome of adult patients with severe acute respiratory failure.
To determine early predictors of outcomes of adult patients with severe acute respiratory failure. ⋯ Early OI (within 3 days) and SOFA score were predictors of mortality in severe acute respiratory failure. In the future, prospective studies measuring serial OIs in a larger scale of study cohort is required to further consolidate our findings.

Acute mesenteric ischemia after cardiac surgery: an analysis of 52 patients.
Acute mesenteric ischemia (AMI) is a rare but serious complication after cardiac surgery. The aim of this retrospective study was to evaluate the incidence, outcome, and perioperative risk factors of AMI in the patients undergoing elective cardiac surgery. ⋯ Prompt diagnosis and early treatment should be initiated as early as possible in any patient suspected of AMI, leading to dramatic reduction in the mortality rate.

Parents' attitudes toward oral rehydration therapy in children with mild-to-moderate dehydration.
According to current guidelines, the first line of treatment for mild-to-moderate dehydration is oral rehydration; the second line is rehydration through a nasogastric tube. Both methods are widely underused. This study was conducted to evaluate parents' attitudes towards rehydration methods used in pediatric emergency departments. ⋯ This is the first study to examine parents' expectations. We found that in the majority of cases, parents' expectations contradict current guidelines. Efforts should be taken to educate parents in order to allow full implementation of the guidelines.

A magnitude 7.1 earthquake hit Canterbury in September 2010. This earthquake and associated aftershocks took the lives of 185 people and drastically changed residents' living, working, and social conditions. ⋯ 24% of ex-smokers resumed smoking following the earthquake, resulting in increased smoking prevalence. Tobacco consumption levels increased in around one-third of current smokers.

Nonlinear analysis of electrocardiography signals for atrial fibrillation.
This paper aims to analyze the electrocardiography (ECG) signals for patient with atrial fibrillation (AF) by using bispectrum and extreme learning machine (ELM). AF is the most common irregular heart beat disease which may cause many cardiac diseases as well. Bispectral analysis was used to extract the nonlinear information in the ECG signals. ⋯ The classification accuracy of ELM to distinguish nonterminating, terminating AF, and terminating immediately AF was 96.25%. In this study, the normal ECG signal was also compared with AF ECG signal due to the nonlinearity which was determined by bispectrum. The classification result of ELM was 99.15% to distinguish AF ECGs from normal ECGs.
