Larger numbers of microemboli detected by transcranial Doppler echocardiography have been linked to adverse neuropsychological outcome after coronary artery bypass grafting. Differences in neurologic outcome have been attributed to different cardioplegia techniques. Transcranial Doppler-detected microembolic events were recorded during coronary artery(More)
BACKGROUND Hypertension is a common disease in patients with chronic kidney disease (CKD) and predisposes to heart disease, stroke, and progression of renal failure. In the general population, sodium restriction has been shown to improve blood pressure (BP) control, but this is not widely recommended in CKD patients. The aim of this study was to assess the(More)
Patients with progressive renal insufficiency are faced with a multitude of decisions and choices during the continuum of their care. Those that choose to embark on the road to renal replacement therapy are faced with complicated decisions regarding modality choice and possibly transplantation. Others may proceed with palliative pre-dialysis care, without(More)
BACKGROUND Cerebral emboli occur during cardiopulmonary bypass and are a principal cause of postoperative neurologic dysfunction. We hypothesized that arterial cannulation of the distal aortic arch, with placement of the cannula tip beyond the left subclavian artery, will result in fewer cerebral microemboli than conventional cannulation of the ascending(More)
OBJECTIVES Cerebral microemboli are responsible to a large extent for the neuropsychiatric deficits after cardiac surgery. Differences in cannula size during cardiopulmonary bypass (CPB) will result in different velocities of blood exiting the aortic cannula. This study determined whether the number of transcranial Doppler (TCD)-detected emboli in the(More)
INTRODUCTION Patients can be used as a resource to enter their own pertinent medical information. This study will evaluate the feasibility of an intelligent computer medical history-taking device directed at patients in the emergency department (ED). METHODS Two of the authors (MB, RE) developed an expert system that can take patient-directed medical(More)
Oral intake (OI) of food and fluid has been associated with hypotension during hemodialysis (HD). Trials evaluating this relationship are small. The objective of this study was to quantify OI and to examine its association with hypotension during HD. This is a cross-sectional retrospective chart review study of 3 consecutive HD runs (dialysate iCa=1.25(More)
More frequent and intensive hemodialysis (HD) schedules continue to garner interest internationally. Two dominant regimens have emerged, namely short-daily and nocturnal HD. A growing body of observational data suggests that these regimens allow more rigorous control of biochemical and physical parameters when compared with conventional HD. This review(More)
