We test the hypothesis that the odds of self-reported receipt of lifestyle advice from a health care provider will be lower among outpatient cardiac rehabilitation (OCR) nonattendees and nonreferred patients compared to OCR attendees. Logistic regression was used to analyse cross-sectional data provided by 65% (4971/7678) of patients aged 20 to 84 years discharged from public hospitals with a d...

Scarce data exist concerning the prevalence of irritable bowel syndrome in adolescence. Changes in lifestyle, presence of stressors and psychological vulnerability during this stage of life place adolescents in the risk group for irritable bowel syndrome. The aim of this study is to determine the prevalence of irritable bowel syndrome in adolescents who are about to begin their university studi...

BACKGROUND The Institute of Medicine has identified the comparative effectiveness of renal replacement therapies as a kidney-related topic among the top 100 national priorities. Given the importance of ensuring internal and external validity, the goal of this study was to identify potential sources of bias in observational studies that compare outcomes with different dialysis modalities. METH...

Background and Purpose—Patients with carotid occlusive disease and stage 2 cerebral hemodynamic failure, characterized by an increased oxygen extraction fraction (OEF) as measured by positron emission tomography (PET) and otherwise known as misery perfusion, have a high risk of cerebral ischemia and subsequent stroke. In clinical practice, the detection of patients with misery perfusion through...

The intraerythrocytic malaria parasite derives much of its requirement for amino acids from the digestion of the hemoglobin of its host cell. However, one amino acid, isoleucine, is absent from adult human hemoglobin and must therefore be obtained from the extracellular medium. In this study we have characterized the mechanisms involved in the uptake of isoleucine by the intraerythrocytic paras...

Many viruses regulate gene expression, both globally and specifically, to achieve maximal rates of replication. During herpes simplex virus 1 infection, translation of the DNA polymerase (Pol) catalytic subunit is inefficient relative to other proteins of the same temporal class (D. R. Yager, A. I. Marcy, and D. M. Coen., J. Virol. 64:2217-2225, 1990). To investigate the mechanisms involved in ...
