CONTEXT Patients with unstable angina/non-ST-segment elevation myocardial infarction (MI) (UA/NSTEMI) present with a wide spectrum of risk for death and cardiac ischemic events. OBJECTIVE To develop a simple risk score that has broad applicability, is easily calculated at patient presentation, does not require a computer, and identifies patients with(More)
BACKGROUND Antithrombotic therapy with heparin plus aspirin reduces the rate of ischemic events in patients with unstable coronary artery disease. Low-molecular-weight heparin has a more predictable anticoagulant effect than standard unfractionated heparin, is easier to administer, and does not require monitoring. METHODS In a double-blind,(More)
BACKGROUND Plasma HIV-1 RNA concentration has been the best predictor for risk of heterosexual and perinatal transmission. However, direct contact with HIV-1 present locally in the genital tract might be necessary for transmission. We aimed to assess the relation between HIV-1 shedding (RNA or culturable virus) in female genital secretions and other factors(More)
Anemia is a common manifestation of HIV infection, occurring in approximately 30% of patients with asymptomatic infection and in as many as 75% to 80% of those with AIDS. Anemia has been associated with decreased quality of life and decreased survival. We performed a cross-sectional study nested within a multicenter prospective cohort study to describe the(More)
CONTEXT HIV-1 RNA and lymphocyte subset levels are the principal indications for antiretroviral treatment. Past reports have differed with regard to the effect of gender and race on these measures and in measures of disease progression. OBJECTIVE To assess racial and gender differences in HIV-1 RNA levels and CD4+ lymphocyte decline. DESIGN A(More)
The multidisciplinary team model of HIV care evolved out of necessity due to the diverse characteristics and needs of people living with HIV disease. Though it is now accepted as the international standard of care, it represents a significant departure from methods of care for other infectious diseases, and debate continues regarding the effectiveness of(More)
In this study, the metabolic performances of a new energy-storing foot (Proteor) and of the solid-ankle cushion heel (SACH) are compared. Twelve patients with traumatic below-knee amputations (mean age: 50.0 +/- 19.9 years) and 12 patients with vascular below-knee amputations (mean age: 73 +/- 7 years) were studied. Oxygen uptake (VO2) was measured in all(More)
Transluminal coronary angioplasty can serve as a model for controlled coronary artery occlusion and reperfusion which enables assessment of short-term changes in collateral vessel filling in patients with severe atherosclerotic coronary artery disease. In 16 patients with isolated left anterior descending or right coronary artery disease (greater than or(More)
The development of a widened mediastinum in patients with neoplastic disease frequently indicates tumor recurrence or spread. Seven cases of mediastinal widening in children with a variety of neoplasms are described wherein the etiology is either proven or strongly suspected to be benign thymic enlargement. Awareness of this benign etiology for mediastinal(More)
BACKGROUND Two phase III trials of enoxaparin for unstable angina/non-Q-wave myocardial infarction have shown it to be superior to unfractionated heparin for preventing a composite of death and cardiac ischemic events. A prospectively planned meta-analysis was performed to provide a more precise estimate of the effects of enoxaparin on multiple end points.(More)
