To investigate the epidemiology, demographics and survival of mucinous adenocarcinomas (MACs), we identified 80,758 MAC patients in the Surveillance, Epidemiology and End Results (SEER) database. The reported incidence of MACs ebbed and flowed over time; however, a significant increase in reported annual age-adjusted incidences of MACs in the appendix, lung and bronchus was observed from 1981 to 2014. The demographics and outcomes of MACs differed by anatomic sites. MACs of the stomach had the largest percentage of poorly differentiated or undifferentiated tumors (41...

BACKGROUND: Oxygen therapy is used liberally for all patients undergoing anaesthesia. Recent studies have raised concerns that it may not be without complications when arterial oxygen concentrations reach supranormal concentrations (hyperoxia). Studies of oxygen therapy have raised concerns that the risk of myocardial injury and infarction is elevated in patients with hyperoxia due to vasoconstriction and formation of reactive oxygen species. Due to lack of symptoms or silent ischaemia, post-operative myocardial injury may be missed clinically...

In patients with stable coronary artery disease, percutaneous coronary intervention is associated with improved outcomes if the lesion is deemed significant by invasive functional assessment using fractional flow reserve. Recent studies have shown that a revascularization strategy using instantaneous wave-free ratio is noninferior to fractional flow reserve in patients with intermediate-grade stenoses. The decision to perform coronary artery bypass grafting surgery is usually based on anatomic assessment of stenosis severity by coronary angiography...
