We compared patients who received an internal-mammary-artery graft to the anterior descending coronary artery alone or combined with one or more saphenous-vein grafts (n = 2306) with patients who had only saphenous-vein bypass grafts (n = 3625). The 10-year actuarial survival rate among the group receiving the internal-mammary-artery graft, as compared with(More)
Differential solute clearances were used to characterize glomerular function in 20 Pima Indians with noninsulin-dependent diabetes mellitus (NIDDM) of less than 3 yr duration. 28 Pima Indians with normal glucose tolerance served as controls. In the diabetic group, the glomerular filtration rate (GFR, iothalamate clearance) exceeded the control value by 15%(More)
Strains of newly emerging Salmonella enterica subsp. enterica (subspecies I) serotype 4,5,12:i:- causing food-borne infections, including a large food poisoning outbreak (n = 86) characterized by persistent diarrhea (14% bloody), abdominal pain, fever, and headache, were examined. The organisms were found in the stool samples from the patients. The(More)
Human behavioural ecology (HBE) can be defined as the evolutionary ecology of human behaviour. Its central focus is how the behaviour of modern humans reflects our species’ history of natural selection. The field has grown rapidly over the last twenty years, in anthropology and other social and behavioural sciences. It passes under many names, including(More)
To evaluate the use of preoperative intravitreal bevacizumab (IVB) in patients undergoing pars plana vitrectomy (PPV) for complications of proliferative diabetic retinopathy (PDR). We studied 22 patients with severe PDR. A preoperative complexity score (CS) was recorded. Eleven eyes were treated with IVB, 1.25 mg, 5–7 days before PPV (group 1), and 11 eyes(More)
We analyzed 91 psychomotor seizures from 31 patients seizure free at least one year after temporal lobectomy (implying temporal lobe onset). Fifty symptoms were looked for in every seizure and their time of onset and ending noted. Statistical analysis was used to define symptom clusters and the order of appearance of symptoms. Of the eighteen most common(More)
Ninety-six patients with greater than or equal to 50% unilateral vertebral artery (VA) stenosis were followed up for an average of 4.6 years. In 89 patients (93%) at least one VA origin was involved, while the intracranial VA was affected in 3 patients (3%). Seventy-four patients (77%) had greater than or equal to 50% stenosis of at least one internal(More)
The Modification of Diet in Renal Disease Trial is a multicenter randomized clinical trial for men and women aged 18-70 years with chronic renal disease who are not on dialysis and who have not had a kidney transplant. Study participants are randomized in a 2 x 2 factorial design to diets containing different amounts of protein and phosphorus and to two(More)
We used receiver operating characteristic (ROC) curve analysis to determine the relative performance of different CSF IgG parameters as diagnostic markers for multiple sclerosis. We quantitated CSF and serum IgG and albumin to determine an IgG albumin ratio, IgG index, Tourtellotte's synthesis rate, and Schuller's formula; CSF free kappa light chains were(More)
