Maximal Strength, Muscular Endurance and Inflammatory Biomarkers in Young Adult Men
2014
The aim was to study associations of maximal strength and muscular endurance with inflammatory biomarkers independent of cardiorespiratory fitness in those with and without abdominal obesity. 686 young healthy men participated (25±5 years). Maximal strength was measured via isometric testing using dynamo-meters to determine maximal strength index. Muscular endurance index consisted of push-ups, sit-ups and repeated squats. An indirect cycle ergometer test until exhaustion was used to estimate maximal aerobic capacity (VO2max). Participants were stratified according to those with (102 cm) and those without abdominal obesity (102 cm) based on waist circumference. Inflammatory factors (C-react…
Involvement of insulin resistance in normoglycaemic obese patients with periodontitis: A cross-sectional study
2017
Aim We explored the association between obesity and periodontitis with the aim of determining the possible role of insulin resistance (IR) in this relationship. Materials and Methods A total of 212 subjects –110 obese and 102 lean individuals– were evaluated for periodontal disease and divided according to IR: a lean group without IR (LWIR); an obese group without IR (OWIR); and an obese group with IR (OIR). Anthropometric, metabolic, inflammatory and periodontal parameters were evaluated. Results Periodontitis was more prevalent in obese (80.9%) than in lean subjects (41.2%), with the former group showing a risk of periodontitis six-fold that of the latter. Obese subjects as a whole displa…
Gender variations of body composition, muscle strength and power output in morbid obesity
2005
BACKGROUND: Motor capabilities are reduced in obese (OB) individuals, and this impairment may result also from quantitative variation of muscle mass due to alterations in body composition. OBJECTIVE: This study aims to evaluate the differences in body mass (BM) and composition, as well as in muscle strength (ST) and power output W(.) between OB and NW males and females, and to test the hypothesis that variations in body composition affect muscle performance in OB subjects. DESIGN AND METHODS: Body composition (determined by BIA with a two-compartment model), upper and lower limb maximum ST (evaluated with isotonic machines) and lower limb maximum anaerobic W(.) (measured with a jumping test…
Laparoscopic gastric banding as a universal method for the treatment of patients with morbid obesity.
2004
Introduction: This study analyzed the influence of potentially negative predictors such as sweet-eating behavior, super-obesity, social and psychological status, family and education situation, intake of sedative drugs, and the distance between hospital and home on the outcome of laparoscopic adjustable gastric banding (LAGB). Methods: 77 women and 29 men with mean age 40.6 years (28-47) underwent LAGB. Preoperative mean body weight was 146 kg (99-179), and mean BMI was 48.1 kg/m 2 (36.4-73.5). The influence of the above-mentioned potentially negative predictors on weight loss was the primary end point. Results: Mean follow-up was 44.6 ′ 19.7 months. Follow-up was possible in all but 6 pati…
Homocysteine levels and the metabolic syndrome in a Mediterranean population: A case-control study
2011
Hyperhomocysteinemia (HH) and metabolic syndrome (MS) are associated with increased cardiovascular risk. However, whether there is a link between MS or its components and homocysteine levels in a population without cardiovascular disease is not well established. We conducted a case-control study in 61 MS patients (41 males, 20 females, aged 51 ± 11 years) and in 98 controls without MS (59 males, 39 females, aged 50 ± 10 years) to ascertain the association between MS and HH, and with inflammatory markers. MS was classified according to the updated ATPIII criteria [17]. No differences in homocysteine levels were observed when comparing MS patients and controls (12.0 ± 3.18 μM vs. 11.9 ± 3.5 μ…
Renal plasma flow, filtration fraction and microalbuminuria in hypertensive patients: Effects of chronic smoking
2005
SUMMARY: Introduction: Albumin excretion rate is usually increased in people who smoke, but the physiological basis of this phenomenon is not fully understood. Methods: The effect of chronic smoking on renal haemodynamics was studied in a cohort of 66 men. Twenty-seven were smokers and 36 were hypertensive. In all subjects, the albumin excretion rate was evaluated; in hypertensive patients, a renoscintigraphic evaluation of renal plasma flow and glomerular filtration were carried out and the filtration fraction was calculated. Results: The hypertensive smoking population presented an increased urinary albumin excretion rate in comparison with hypertensive non-smoking patients. No signifi…
Central obesity and hypertensive renal disease: association between higher levels of BMI, circulating transforming growth factor beta1 and urinary al…
2004
OBJECTIVE: In this study, the relationship between circulating transforming growth factor beta1 (TGFbeta1) and urinary albumin excretion (UAE) has been investigated in non-obese and central obese hypertensive patients. DESIGN AND PATIENTS: Fifty-eight consecutive hypertensive outpatients both lean and with central obesity were enrolled and divided in three groups, according to their body mass index (BMI) values. Group A: 16 lean hypertensives (men with BMI or = 25 kg/m2 and 24.7 kg/m2 and or = 30 kg/m2 and women with BMI > or = 27.3 kg/m2). MEASURES: In all patients, UAE, by immunonephelometric assay, circulating TGFbeta1 by a solid-phase specific sandwich enzyme-linked immunosorbent assay …
Association of metabolic syndrome and its components with hyperuricemia in a Mediterranean population.
2015
Several studies have found an association between hyperuricemia and metabolic syndrome (MS), although there are discrepancies as to which MS components play a pivotal role in this association. We aimed to investigate the association between serum uric acid (SUA) levels and MS in a Mediterranean population (eastern Spain). We performed a case-control study of 71 patients with MS and 122 healthy controls. MS was defined according to the revised National Cholesterol Education Program Adult Treatment Panel III modified criteria. Hyperuricemia was defined as SUA levels >6.55 mg/dL. We determined biochemical, lipidic and inflammatory parameters along with uric acid. Patients with MS showed a high…
Left ventricular filling abnormalities and obesity-associated hypertension: relationship with overproduction of circulating transforming growth facto…
2005
This study has been designed to evaluate the relationship among transforming growth factor beta1 (TGFbeta1) and some measurements of diastolic function in a population of hypertensive subjects with normal left ventricular ejection fraction. We studied 67 hypertensive outpatients who according to their BMI levels were subdivided into three groups: lean (L), overweight (OW) and obese (OB) hypertensives (HT). Circulating TGFbeta1 and M- and B-mode echocardiography was determined. All hypertensives were further subgrouped, according to European Society of Cardiology Guidelines, into two subsets of patients with normal diastolic function or with diastolic dysfunction. Prevalence of left ventricu…
Left ventricular function response to exercise in normotensive obese subjects: influence of degree and duration of obesity
1992
This study has been designed to evaluate whether duration and severity of obesity can influence left ventricular function response to exercise in obese subjects without other known cardiovascular risk factors such as hypertension, diabetes or hyperlipoproteinemia. A total of 29 obese subjects were included and they were divided, according to their body mass index and to Garrow's criteria as follows: Overweight or mildly obese subjects: body mass index from 25 to 30 kg/m2; moderately obese subjects: body mass index30 and40 kg/m2. Both obese groups were further subdivided according to their duration of obesity evaluated by accurate anamnesis in subgroup A (duration of obesity less than 120 mo…
