INTRODUCTION In obese subjects, the relative reduction of the skeletal muscle strength, the reduced cardio-pulmonary capacity and tolerance to effort, the higher metabolic costs and, therefore, the increased inefficiency of gait together with the increased prevalence of co-morbid conditions might interfere with walking. Performance tests, such as the(More)
BACKGROUND Growth hormone (GH) secretion is normally sensitive to physical exercise. Intensity and duration of exercise, fitness and age can all influence the GH response to exercise. In obesity, GH secretion is decreased both in basal conditions and in response to exercise. OBJECTIVE To analyse the dynamics of GH response to a progressive cycloergometric(More)
Human obesity is characterized by profound alterations in the hemodynamic and metabolic states. Whether these alterations involve sympathetic drive is controversial. In 10 young obese subjects (body mass index, 40.5 +/- 1.2 kg/m2, mean +/- SEM) with normal blood pressure and 8 age-matched lean normotensive control subjects, we measured beat-to-beat arterial(More)
PURPOSE To validate a new obesity-specific disability assessment test: the Obesity-related Disability test (Test SIO Disabilità Obesità Correlata, TSD-OC). METHODS Adult obese individuals were assessed with the TSD-OC, 36-Item Short-Form Health Survey (SF-36), 6-min walking test (6MWT) and grip strength. The TSD-OC is composed of 36 items divided into(More)
Three patients with Cushing's disease and one patient with paraneoplastic hypercortisolism were treated for 24-49 days with the long-acting analogue of somatostatin, SMS 201-995, Sandoz (SMS), administered in increasing doses up to 400-1200 micrograms daily. In the three Cushing's patients during SMS treatment plasma ACTH displayed an initial rise and a(More)
OBJECTIVE Conventional body composition methods may produce biased quantification of fat and fat-free mass in obese subjects, due to possible violation of the assumption of constant (73%) tissue hydration. We used an assumption-free, graphical method for interpreting body weight variation in obesity using bioelectrical measurements. DESIGN 540 obese(More)
Several mutations in the melanocortin receptor 4 gene have been identified in humans and account for 3-6% of morbid obesity. In contrast, strong evidence of a causative role for melanocortin receptor 3 (MC3R) mutations are still lacking. In MC3R knockout mice, high feed efficiency rather than hyperphagia seems to contribute to increased fat mass. On the(More)
This study investigates motor (MNCS) and sensory (SNCS) nerve conduction in a sample of non-diabetic obese people without symptoms suggestive of neuropathy and looks for a possible metabolic alteration. Twenty-one patients and 20 age-matched controls underwent (a) MNCS (median, ulnar, peroneal, and tibial) and SNCS (median, ulnar, and sural); (b)(More)
