Physical activity is associated with a reduced incidence of coronary disease, but the mechanisms mediating this effect are not defined. There has been considerable recent interest in inflammation in the pathogenesis of cardiovascular disease. Some of the beneficial role of physical activity may result from its effects on the inflammatory process. We(More)
Peripheral arterial disease (PAD) is a common manifestation of atherosclerosis affecting 5 million adults in the United States, with an age-adjusted prevalence of 4% to 15% and increasing up to 30% with age and the presence of cardiovascular risk factors. In this article we focus on lower extremity PAD and specifically on the superficial femoral and(More)
Although much of personality disorder research depends on diagnostic data obtained directly from patients, this approach has rarely been compared to interviews with knowledgeable informants. The purpose of this study was to determine the diagnostic agreement between these two assessment methods, as well as their relative contribution to the formulation of(More)
OBJECTIVE Suicidal behavior is prevalent in individuals with schizophrenia. Although a relationship between greater awareness of illness and suicidal behavior has been posited, the question has not been systematically studied. The purpose of this study was to examine the relationship between suicidal behavior and various aspects of insight in 218 patients(More)
BACKGROUND The optimal degree of heparin anticoagulation for peripheral vascular interventions (PVIs) has not been defined. We sought to correlate total heparin dose and peak procedural activated clotting time (ACT) with postprocedural outcomes in patients undergoing PVI. METHODS AND RESULTS We studied 4743 patients who received heparin during PVIs in a(More)
BACKGROUND Endothelial dysfunction precedes overt atherosclerosis and is present in patients with type 2 diabetes mellitus (T2DM). Myocardial perfusion imaging (MPI) is an effective method of detection of coronary artery disease (CAD); however, the relationship between endothelial function and MPI in asymptomatic patients with T2DM has not been examined.

Malignancies may cause cholestatic jaundice through well-recognized mechanisms (e.g., bile duct obstruction or widespread hepatic infiltration). Paraneoplastic syndromes associated with malignancy, particularly with renal cell carcinoma (Stauffer's syndrome) and malignant lymphoproliferative diseases, can induce a reversible form of cholestasis through an(More)
Pericarditis is a common disorder that has multiple causes and presents in various primary-care and secondary-care settings. It is diagnosed in 0.1% of all hospital admissions and in 5% of emergency room visits for chest pain. Despite the advance of new diagnostic techniques, pericarditis is most commonly idiopathic, and radiation therapy, cardiac surgery,(More)

Spontaneous hemopericardium is extremely rare in patients with hemophilia and has never been reported in hemophilia B-factor IX deficiency. We report a patient with hemophilia B who presented with spontaneous hemopericardium and tamponade requiring emergent pericardiocentesis. As advances in therapies improve the longevity and quality of life of patients(More)
