The basal energy expenditure of female athletes vs. sedentary women as related to their family history of type 2 diabetes
2001
The purpose of this study was to investigate the basal metabolic rate (BMR) in 16 professional sportswomen (soccer players) versus 15 sedentary women, as related to the presence (FH+) or absence (FH-) of a family history of type 2 diabetes. The sportswomen, in toto, had a significantly higher BMR than expected from predictive equations (+14.92%). However, the difference was limited only to FH- sportswomen (+18.66%, p<0.0005). FH- sportswomen showed a significantly higher measured BMR than FH+ sportswomen (p<0.005), and FH+ (p=0.058) and than FH- (p<0.05) sedentary women. There were no other significant differences relative to physical, metabolic and plasmatic data between the groups. The sp…
Clinical applicability and cost-effectiveness of DIABSCORE in screening for type 2 diabetes in primary care
2017
Aims: To evaluate the applicability and cost-effectiveness of a clinical risk score (DIABSCORE) to screen for type 2 diabetes in primary care patients. Methods: Multicenter cross-sectional study of 10,508 adult no previously diagnosed with diabetes, in 2 Spanish regions (Canary Islands and Valencian Community). The variables comprising DIABSCORE were age, waist to height ratio, family history of diabetes and gestational diabetes. ROC curves were obtained; the diabetes prevalences odds ratios (HbA1c >= 6.5%) between patients exposed and not exposed to DIABSCORE >= 100, and to fasting blood glucose >= 126 mg/dL were calculated. The opinions of both the professionals and the patients concernin…
Visceral adiposity index and DHEAS are useful markers of diabetes risk in women with polycystic ovary syndrome
2014
ObjectiveOn the basis of the known diabetes risk in polycystic ovary syndrome (PCOS), recent guidelines of the Endocrine Society recommend the use of an oral glucose tolerance test (OGTT) to screen for impaired glucose tolerance (IGT) and type 2 diabetes (T2DM) in all women with PCOS. However, given the high prevalence of PCOS, OGTT would have a high cost–benefit ratio. In this study, we identified, through a receiver operating characteristic analysis, simple predictive markers of the composite endpoint (impaired fasting glucose (IFG) or IGT or IFG+IGT or T2DM) in women with PCOS according to the Rotterdam criteria.DesignWe conducted a cross-sectional study of 241 women with PCOS in a unive…
Effects of Aging on Serum Ionized and Cytosolic Free Calcium
1999
Abstract —Elevated cytosolic free calcium (Ca i ) and reciprocally reduced, extracellular ionized calcium (Ca-ion) levels are observed in both hypertension and non–insulin-dependent diabetes mellitus (NIDDM). Because the changes of vascular function and insulin sensitivity in these conditions resemble the changes associated with “normal” aging, we wondered to what extent similar alterations in calcium metabolism occur with aging per se in the absence of overt hypertension or diabetes. We therefore measured platelet Ca i levels by spectrofluorometry and serum Ca-ion levels in normotensive, nondiabetic, healthy, normal, elderly (>65 years old) subjects, mean age ±SEM, 72.2±1.5 years old (…
Glycated albumin with loss of fatty acid binding capacity contributes to enhanced arachidonate oxygenation and platelet hyperactivity: relevance in p…
2014
High plasma concentrations of nonesterified fatty acids (NEFAs), transported bound to serum albumin, are associated with type 2 diabetes (T2D). The effects of albumin on platelet function were investigated in vitro. Modifications of albumin, such as those due to glycoxidation, were found in patients with T2D, and the consequences of these modifications on biological mechanisms related to NEFA handling were investigated. Mass spectrometry profiles of albumin from patients with T2D differed from those from healthy control subjects. Diabetic albumin showed impaired NEFA binding capacity, and both structural and functional alterations could be reproduced in vitro by incubating native albumin wi…
Nitric Oxide Production and Arachidonic Acid Metabolism in Platelet Membranes of Coronary Heart Disease Patients with and without Diabetes
2001
<i>Aim:</i> To evaluate the levels of nitrite (NO<sup>–</sup><sub>2</sub>) and nitrate (NO<sup>–</sup><sub>3</sub>) ions and the incorporation of [<sup>3</sup>H]arachidonic acid (AA) into phospholipids of platelet membranes from coronary artery disease (CAD) patients with and without diabetes (NIDDM). <i>Subjects and Methods:</i> Eighteen CAD patients (group A), 18 CAD patients with NIDDM (group B), and 20 healthy controls (group C) without dyslipidemia, peripheral vascular disease and hypertension were included in the study. The groups were matched for age, sex and body mass index. The diagnosis of CAD was …
Cytosolic Ca2+Content and Membrane Fluidity of Platelets and Polymorphonuclear Leucocytes in Diabetes Mellitus
1995
Considering the role played by platelets and leucocytes in diabetic disease and keeping in mind the strong correlation between functional and metabolic aspects that characterizes this clinical condition, we evaluated, in two groups of diabetics, respectively the platelet and polymorphonuclear (PMN) cytosolic Ca2+ content (employing the fluorescent probe Fura 2-AM) and membrane fluidity (using the fluorescent probe TMA-DPH and considering the fluorescence polarization degree, inversely related to the membrane fluidity). From the obtained results, it is evident that the platelet cytosolic Ca2+ content does not distinguish normals from diabetics of type 1 and 2; the platelet membrane fluidity …
Influence of family history of NIDDM on basal metabolic rate in sedentary and active women
2011
Aim and methods: The influence of family history of non-insulin-dependent diabetes (NIDDM) on basal metabolic rate (BMR) has been investigated in 116 voluntarily women: 25 sedentary and 34 athletes without a family predisposition to type 2 diabetes (FH-); 21 sedentary and 15 athletes with a second degree predisposition to NIDDM (FH +); 10 sedentary and 11 athletes with a first degree predisposition to NIDDM (FH ++). Results: The results showed that family history on type 2 diabetes is strongly related to sedentary in women with significant high body weight values and an increased fat mass. There was no significant difference in the body parameters among the athletes groups, confirming the p…
Causal relationship of hepatic fat with liver damage and insulin resistance in nonalcoholic fatty liver
2017
Abstract Background and Aims Nonalcoholic fatty liver disease is epidemiologically associated with hepatic and metabolic disorders. The aim of this study was to examine whether hepatic fat accumulation has a causal role in determining liver damage and insulin resistance. Methods We performed a Mendelian randomization analysis using risk alleles in PNPLA3, TM6SF2, GCKR and MBOAT7, and a polygenic risk score for hepatic fat, as instruments. We evaluated complementary cohorts of at‐risk individuals and individuals from the general population: 1515 from the liver biopsy cohort (LBC), 3329 from the Swedish Obese Subjects Study (SOS) and 4570 from the population‐based Dallas Heart Study (DHS). Re…
