Bioelectrical characteristics of type 1 and type 2 diabetic subjects with reference to body water compartments.
1998
Since bioelectrical characteristics correspond well to body water compartments, this study investigated bioelectrical differences between type 1 and type 2 diabetic subjects that could reflect differences in body water compartments. We investigated cross-sectionally 612 adult subjects, classified into 10 groups according to sex and disease (control, obese normal glucose tolerant, non-obese type 2 diabetes, obese type 2 diabetes, type 1 diabetes). Resistance (R), reactance (Xc) and phase angle (PA) were measured (800 microA - 50 kHz alternating current). The bioelectrical vector was obtained by plotting R and Xc normalized for height (ht), it is easily identified on the basis of the length (…
The effects of muscular exercise on glucose, free fatty acids, alanine and lactate in type I diabetic subjects in relation to metabolic control.
1988
Metabolic effects of muscular exercise were studied in eleven subjects with type I diabetes mellitus during poor metabolic control, and again during good metabolic control, and in ten healthy control subjects. All the subjects were submitted to a submaximal gradual triangular test on an electrically braked bicycle ergometer; glucose, FFA, alanine and lactate were measured at rest, and after exercise. In poorly controlled patients, glucose and FFA were unchanged after exercise, whereas blood alanine and lactate increased by a percentage similar to that of the controls, and well-controlled diabetic patients. Baseline alanine concentrations were lower and lactate concentrations higher than in …
Aceruloplasminaemia: a family with a novel mutation and long-term therapy with deferasirox.
2014
Ceruloplasmin is a member of the multicopper oxidase family that plays a major role in the transport of iron in the body. Aceruloplasminaemia (ACP) is a rare disease and is clinically identified by iron overload in liver, pancreas, brain, and other organs, and by microcytic anaemia. So far, the iron chelator deferasirox was given for therapy only up to 6 months due to side effects. Here, we describe a novel mutation leading to ACP and report for the first time a long-term therapy, that is, 2 years with deferasirox. ACP was diagnosed in 3 siblings using clinical and biochemical characteristics, HFE and ceruloplasmin mutational analysis, liver biopsy, brain-, liver-, and heart-MRI. For iron d…
The relationship between type 2 diabetes family history, body composition and blood basal glycemia in sedentary people.
2013
The aim of this study was to verify whether there is a positive correlation between family history to type 2 diabetes mellitus and body mass and composition, and alterations in blood basal glycaemia levels in sedentary male and female. Anthropometric variables, blood parameters, body composition and body surface area were evaluated on 183 male and 237 female sedentary individuals. Participants were classified into two groups: FH(+) (family history positive) and FH(-) (familiar history negative) according to their medical history. The FH(+) group showed higher values of body mass and body surface area than FH(-) group. These differences were statistically significant (p < 0.05) for the femal…
How often patients on insulin therapy measure postprandial glycemia and modify insulin doses accordingly? From an on-line survey in insulin-treated d…
2019
Abstract Introduction Controlling postprandial glycemia (PPG) is important to achieve optimal glycemic control, but few studies have evaluated how often is measured and evaluated. Objectives To evaluate how often patients on insulin therapy measure PPG and modify insulin doses accordantly. As secondary objectives, we evaluated the factors conditioning elevated PPG and associated issues. Material and methods Cross-sectional observational study based on a web-based survey from an unselected sample of adult insulin-treated patients. A p-value of Results 1251 patients (68% women, 38.9 ± 13 years [mean ± SD], body mass index (BMI) 24.2 ± 4.2 kg/m2, diabetes duration 17.4 ± 12.8 years, insulin d…
Microvascular skin blood flow following the ingestion of 75 g glucose in healthy individuals.
2009
It is expected that microvascular blood flow might be affected by blood glucose, blood insulin and C-peptide levels. In our investigation skin microvascular blood flow (LDF) was measured using laser doppler fluxometry at skin temperatures of 37 degrees C and 44 degrees C during a 75 g oral glucose load (OGT) or water in ten healthy volunteers (6 male, 4 female, age: 28.1+/-4.0) who had fasted overnight. The transcutaneous oxygen tension (tcPO2) was measured using a transcutaneous oxygen electrode at a temperature of 44 degrees C. The microvascular response to acetylcholine was investigated before the start of the ingestion period and after 30 minutes. In addition, the capillary blood cell v…
A study of insulin resistance using the minimal model in nondiabetic familial combined hyperlipidemic patients.
1998
The presence of insulin resistance in 20 male nondiabetic patients with familial combined hyperlipidemia (FCH) and 20 controls of similar age and body mass index (BMI) was investigated using the minimal model method modified by the administration of insulin and an oral glucose tolerance test. The peripheral sensitivity of insulin, expressed as the insulin sensitivity index (Si), was 1.91 ± 1.05 and 2.86 ± 1.19 × 10−4 · min−1 · mU/L in FCH patients and controls, respectively (P < .01), and the corresponding value for the peripheral utilization of glucose independently of insulin (Sg) was 1.70 ± 1.13 in FCH patients and 2.35 ± 0.60 × 10−2 · min−1 in controls (P < .02). In the FCH group, the S…
Levels of C3 in patients with severe, morbid and extreme obesity: its relationship to insulin resistance and different cardiovascular risk factors.
2007
Increased C3 has been related to body mass index (BMI) and insulin resistance, although there are not sufficient studies in subjects with morbid obesity. The purpose of this study was to evaluate the levels of C3 as a function of the BMI in subjects of both sexes, with severe, morbid and extreme obesity, and their possible relationship to insulin resistance or associated diseases such as diabetes, hypertension and dyslipidemia.The study included a total of 316 patients (110 men and 206 women) with severe obesity (17.1%), morbid obesity (54.4%) and extreme obesity (28.4%), with an average BMI of 46.70+/-7.37 kg/m2.The glucose and insulin levels were determined baseline, and 2 h after a 75 g …
Clinical and metabolic effects of first-line treatment with somatostatin analogues or surgery in acromegaly: a retrospective and comparative study.
2012
To evaluate the metabolic effects of first-line somatostatin analogues or surgery in acromegaly. Retrospective, comparative, 12-month follow-up. Two hundred and thirty one patients (123 men, age 47.32 ± 14.63 years) with active acromegaly, first line treatments were somatostatin analogues in 151 (65.4%) and surgery in 80 (34.6%). Metabolic syndrome (MS) parameters, glucose, insulin and GH during oral glucose tolerance test, stimulated insulin sensitivity by insulin sensitivity index (ISI Matsuda), early and total insulin-secretion rate by insulinogenic index and AUC(INS), visceral adiposity function, expressed by visceral adipose index (VAI). Somatostatin analogues treatment improved all MS…
Acute effects of coffee on endothelial function in healthy subjects
2010
Background/Objectives: Coffee is the most widely consumed beverage in the world, but its effect on the cardiovascular system has not been fully understood. Coffee contains caffeine and antioxidants, which may influence endothelial function, both of which have not yet been investigated. The objective of this study was to investigate the acute effects of coffee on endothelial function measured by brachial artery flow-mediated dilation (FMD). Subjects/Methods: A total of 20 (10 males and 10 females) healthy non-obese subjects underwent a double-blind, crossover study. Subjects ingested one cup of caffeinated (CC) and one cup of decaffeinated (DC) Italian espresso coffee in random order at 5- t…
