Persistence of antibiotic resistance genes from river water to tap water in the Yangtze River Delta.

Antibiotic resistance genes (ARGs) raise public concern as emerging contaminants. The abundance and variation of 11 ARGs, intI1 and 16S rRNA gene were deciphered using quantitative PCR (qPCR) in two drinking water treatment systems that include river, wetland, drinking water treatment plants (DWTPs) and tap water from the Yangtze River Delta. The influencing factors for ARG abundance in river water were also explored.

Does Dexamethasone Reduce Hospital Readiness for Discharge, Pain, Nausea, and Early Patient Satisfaction in Hip and Knee Arthroplasty? A Randomized, Controlled Trial.

Background: Reduction in postoperative pain, nausea, and vomiting in patients undergoing total joint arthroplasty may facilitate earlier discharge from hospital and reduce healthcare costs. This study was performed to primarily assess whether perioperative dexamethasone reduced hospital length of stay and to assess the effect on pain, nausea and vomiting, and patient satisfaction.

Methods: One hundred sixty-four patients undergoing total hip arthroplasty or total knee arthroplasty were randomized to receive either 8 mg intravenous dexamethasone (n = 86) or placebo (n = 78) at induction and at 24 hours postsurgery.

Non-ST elevation myocardial infarction with occluded artery and its clinical implications.

Background: This study aimed to determine the prevalence and differences between Non-ST elevation Myocardial Infarction (NSTEMI) with an occluded culprit artery (NSTEMIOA) and NSTEMI with a patent culprit artery (NSTEMIPA).

Methods: We conducted a retrospective observational study on NSTEMI patients admitted between 01/01/2010 to 30/06/2010. The inclusion criteria were diagnosis of NSTEMI and inpatient coronary angiogram.
