glucocorticosteroids are mainly used for inflammatory and non-inflammatory diseases as well as cancers. unawareness of their function, indications and side effects may lead to patient’s hazard. thus, medical staff should be completely familiar with these drugs.objectives: promoting medical staff knowledge about glucocorticoids’ side effects, function and indications. promoting their knowledge a...
OBJECTIVE To identify factors that influence survival after diabetes-related amputations. RESEARCH DESIGN AND METHODS We abstracted medical records of 1,043 hospitalized subjects with diabetes and a lower-extremity amputation from 1 January to 31 December 1993 in six metropolitan statistical areas in south Texas. We identified mortality in the 10-year period after amputation from death certif...
BACKGROUND We conducted a prospective longitudinal study to investigate the yet unknown clinical significance of myocardial fibrosis in patients with non-ischemic cardiomyopathy without history of congestive heart failure (CHF). METHODS AND RESULTS At 3 tertiary referral centers, 228 patients with non-ischemic cardiomyopathy without history of CHF were studied with cardiovascular magnetic res...
BACKGROUND The impact of percutaneous coronary intervention (PCI) on chronic total occlusion in patients with well-developed collaterals is not clear. METHODS AND RESULTS A total of 640 chronic total occlusion patients with collateral flow grade ≥2 were divided into 2 groups; chronic total occlusion patients either treated with PCI (the PCI group; n=305) or optimal medical therapy (the optima...
BACKGROUND To investigate the incidence of death and of new cardiovascular events at long-term follow-up of patients with and without PAD seen in a vascular surgery clinic. MATERIAL/METHODS We investigated the incidence of death, new stroke/transient ischemic attack, new myocardial infarction, new coronary revascularization, new carotid endarterectomy, new peripheral arterial disease (PAD) re...
OBJECTIVE To provide reliable age- and region-specific estimates of the associations between diabetes and major cardiovascular diseases and death in populations from the Asia-Pacific region. RESEARCH DESIGN AND METHODS Twenty-four cohort studies from Asia, Australia, and New Zealand (median follow-up, 5.4 years) provided individual participant data from 161,214 people (58% from Asia) of whom ...
BACKGROUND Cardiac sarcoidosis is associated with an increased risk of heart failure and sudden death, but its risk in patients with preserved left ventricular ejection fraction is unknown. Using cardiovascular magnetic resonance in patients with extracardiac sarcoidosis and preserved left ventricular ejection fraction, we sought to (1) determine the prevalence of cardiac sarcoidosis or associa...
BACKGROUND Kernel smoothing method is a non-parametric or graphical method for statistical estimation. In the present study was used a kernel smoothing method for finding the death hazard rates of patients with acute myocardial infarction. METHODS By employing non-parametric regression methods, the curve estimation, may have some complexity. In this article, four indices of Epanechnikov, Biqu...
BACKGROUND Allopurinol reduces oxidative stress and interacts with purinergic signalling systems important in bone metabolism and muscle function. We assessed whether allopurinol use was associated with a reduced incidence of hip fracture in older people. METHODS Analysis of prospective, routinely-collected health and social care data on patients undergoing health and social work assessment i...
INTRODUCTION AND OBJECTIVES We sought to assess the prognostic value of exercise-induced left ventricular systolic dysfunction in hypertensive patients with normal resting echocardiography and absence of coronary artery disease. METHODS From our database of patients referred for treadmill exercise echocardiography, we identified 93 hypertensive patients with preserved resting left ventricular...
