The effect of daily ambient air pollution was examined within a cohort of 846 asthmatic children residing in eight urban areas of the USA, using data from the National Cooperative Inner-City Asthma Study. Daily air pollution concentrations were extracted from the Aerometric Information Retrieval System database from the Environment Protection Agency in the USA. Mixed linear models and generaliz...

Background Recent studies investigating the implications of additional ablation guided by dormant pulmonary vein (PV) conduction testing using adenosine showed conflicting results, and the data about atrial fibrillation (AF) recurrence after trigger site elimination in adenosine-induced AF are still lacking. Methods Of 846 patients with paroxysmal AF (PAF) who underwent PV isolation (PVI), ad...

Abstract Introduction Obesity affects an increasing proportion of orthopaedic patients. Arthroplasties on this sub-population are associated with increased complications(anatomical issues to peri-operative complications/infection). It is postulated patients BMI have longer inpatient stay. Is the case in our elective department at Fairfield General Hospital? there a basis implement cut-off for a...

Burnout among general practitioners (GPs) is a problem in many countries. Research indicates that burnout less likely to occur intrinsically motivated employees. Based on self-determination theory, we investigate 1) whether GPs are burned out than their colleagues, and 2) the most more burn when exposed an external regulatory accreditation programme. General practices Denmark were cluster rando...

BACKGROUND We aimed to establish the prevalence of amphotericin B deoxycholate (AmBd)-related toxicities among South African patients with cryptococcosis and determine adherence to international recommendations to prevent, monitor and manage AmBd-related toxicities. METHODS Clinical data were collected from cases of laboratory-confirmed cryptococcosis at 25 hospitals, October 2012 -February 2...

As satellite payload electrical power system requirements continue to grow, satellite systems employing flat panel arrays have reached limits set by either on-orbit dynamics that limit the size and shape of the deployed array, mass constraints set by the launch vehicle, or by the limits set by the volume constraints of the launch shroud. This has caused several satellite programs to approach po...

A BSTRACT Background Cardiovascular complications are the most important causes of perioperative morbidity and mortality among patients undergoing major vascular surgery. Methods We performed a randomized, multicenter trial to assess the effect of perioperative blockade of beta-adrenergic receptors on the incidence of death from cardiac causes and nonfatal myocardial infarction within 30 days a...
