Currently, at least 3 major forms of therapy are(More)
Compared with young adults, fat oxidation is lower in elderly persons during endurance exercise performed at either the same absolute or relative intensity. We evaluated the effect of 16 wk of endurance training on fat and glucose metabolism during 60 min of moderate intensity exercise [50% of pretraining peak oxygen consumption (VO2peak)] in six elderly(More)
We evaluated the effect of aging on fat and carbohydrate metabolism during moderate intensity exercise. Glycerol, free fatty acid (FFA), and glucose rate of appearance (Ra) in plasma and substrate oxidation were determined during 60 min of cycle ergometer exercise in six elderly (73 +/- 2 yr) and six young adults (26 +/- 2 yr) matched by gender and lean(More)
To identify the association between the polymorphisms of genes encoding alcohol metabolizing enzymes and alcoholism, the alcohol dehydrogenase 2 (ADH2), alcohol dehydrogenase 3 (ADH3), aldehyde dehydrogenase 2 (ALDH2), and cytochrome P450 2E1 (CYP2E1) genes were studied in 101 male Mexican American alcoholics. One hundred and four Mexican American(More)

PATIENTS/PARTICIPANTS All subjects (n = 694) discharged alive from July 1, 1990, to June 30, 1991, who had a diagnosis of acute myocardial(More)
OBJECTIVE To describe the effect of age on the care of patients hospitalized with acute myocardial infarction (MI). DESIGN Retrospective chart review of all cases with a primary or secondary discharge diagnosis of acute MI. SETTING Two large community hospitals in Milwaukee, Wisconsin, from July 1, 1990 to June 30, 1991. PATIENTS There were 771 charts(More)
Gastrointestinal cancers are common in the elderly. In the 1990s, modest advances in the early diagnosis, staging, and treatment of gastrointestinal cancers were made. Emphasis has been placed on screening for colorectal cancer; development of new diagnostic and staging modalities, particularly endoscopic ultrasound; and introduction of new treatment(More)
Management of malignant gastrointestinal obstruction presents a significant challenge. Most patients are in a profoundly decompensated state due to underlying malignancy and are not ideal candidates for invasive surgical procedures. In recent years, self-expandable metal stents (SEMS) have emerged as an effective and safe, less invasive alternative for the(More)
Nutritional therapy of a patient with approximately 100 cm of remaining jejunum, severe malabsorption, and high jejunostomy output is presented. A high-calorie diet, oral rehydration therapy, and vitamin and mineral supplementation were used effectively to maintain a reasonable nutritional state without the need for long-term intravenous therapy.
