In patients with type 1 diabetes, measurement of connecting peptide (C-peptide), cosecreted with insulin from the islets of Langerhans, permits estimation of remaining beta-cell secretion of insulin. In this retrospective analysis to distinguish the incremental benefits of residual beta-cell activity in type 1 diabetes, stimulated (90 min following(More)
BACKGROUND Chronicity of muscle weakness from cancer and its treatment may be problematic, particularly in those treated for cancer during childhood. We compared body composition, muscle strength, and mobility between 75 adult survivors of childhood acute lymphoblastic leukemia (ALL) and expected values based on population normative data. METHODS Subjects(More)
BACKGROUND The purpose of the study was to determine the prevalence of metabolic syndrome, growth hormone deficiency, and cardiovascular risk factors among adult survivors of childhood acute lymphoblastic leukemia (ALL) treated with or without cranial irradiation. METHODS Follow-up was undertaken of 75 randomly selected long-term childhood ALL survivors.(More)
Excessive weight gain in a subset of intensively treated Diabetes Control and Complications Trial (DCCT) subjects was associated with higher waist to hip ratio; higher triglyceride (TG), low-density lipoprotein (LDL) cholesterol, and apolipoprotein B (ApoB) in the presence of small-dense LDL; and decreased high-density lipoprotein 2 cholesterol (HDL2-C),(More)
We hypothesized that a whey protein diet would result in greater weight loss and improved body composition compared with standard weight loss diets. Weight change, body composition, and renin-angiotensin aldosterone system activity in midlife adults were compared between diet groups. Eighteen subjects enrolled in a 5-month study of 8-week controlled food(More)
HDL subspecies Lp(A-I) and Lp(A-I,A-II) have different anti-atherogenic potentials. To determine the role of lipoprotein lipase (LPL) and hepatic lipase (HL) in regulating these particles, we measured these enzyme activities in 28 healthy subjects with well-controlled Type 1 diabetes, and studied their relationship with Lp(A-I) and Lp(A-I,A-II). LPL was(More)
OBJECTIVE This population study examines the relationship between LDL density and persistent albuminuria in subjects with type 1 diabetes at the end of the Diabetes Control and Complications Trial (DCCT). RESEARCH DESIGN AND METHODS Subjects were classified as persistently normoalbuminuric (albumin excretion rate [AER] < 30 mg/d, n = 1,056),(More)
BACKGROUND & AIMS There is a growing need for clinically applicable body composition assessment tools for extremely obese individuals. The objective of this research was to evaluate several bioimpedance techniques for monitoring changes in fluid, particularly intracellular water (reflecting body cell mass) after bariatric surgery. DESIGN Fifteen extremely(More)
BACKGROUND Microalbuminuria (MA), a predictor of cardiovascular disease in subjects without diabetes and with type 2 diabetes, is more common in men than women in some studies. MA has been linked to central obesity-related traits, including increased waist-hip ratio (WHR), suggesting visceral adiposity might contribute to elevated albumin excretion rate(More)
The objective of this study is to evaluate the effectiveness of a small group intervention in improving knowledge, feeling of control, and behaviors related to self-management of diabetes. The intervention includes educational content on diabetes self-management as well as discussion of attitudes, feelings, and motivations about living with diabetes. The(More)
