Relationship between childhood obesity cut-offs and metabolic and vascular comorbidities: comparative analysis of three growth standards
2013
Background: To compare the association between metabolic and vascular comorbidities and the body mass (BMI)-for-age cut-off criteria from three growth standards [Centers for Disease Control and Prevention (CDC), 2000; World Health Organization (WHO), 2007; Spanish Reference Criteria (Carrascosa Lezcano et al., 2008)] that are used to define being overweight and obese in childhood. Methods: A prospective study was conducted in 137 children (aged 8–16 years). Based on BMI-for-age Z-scores according to WHO cut-offs, 59 participants were obese, 35 were overweight and 43 were normal-weight. All participating children were subsequently reclassified applying the CDC and Spanish Reference Criteria.…
The role of morbid obesity in the promotion of metabolic disruptions and non-alcoholic steatohepatitis by Helicobacter Pylori
2016
Background Helicobacter pylory (HP) infection has been associated to an increased rate of type 2 diabetes (T2D) and liver disease through its effect on insulin resistance and systemic inflammation. However, results are inconstant and no studies exist in morbidly obese patients, in which both insulin resistance and inflammation coexist. Material and methods Cross-sectional study to evaluate the relationship between HP infection and alterations in carbohydrate metabolism, lipid profile, inflammation markers, and liver disease in patients awaiting for bariatric surgery. HP infection was histologically assessed in gastric antrum biopsy from 416 subjects. Liver biopsy was also available in 93 su…
Short Sleep Duration Is Related to Emerging Cardiovascular Risk Factors in Obese Children
2015
Objective: The aim of the present study was to evaluate the influence of sleep duration on cardiovascular risk factors in obese children. Methods: Cross-sectional analysis of 90 obese children ages 7 to 16 years. Anthropometric and clinical evaluation with specification of dietary and lifestyle habits was carried out during an office visit. Sleep duration was evaluated by the BEARS (B = bedtime issues, E = excessive daytime sleepiness, A = night awakening, R = regularity and duration of sleep, S = snoring) questionnaire on children's sleep characteristics. Sleep time adequacy by age was assessed according to the criteria of the National Sleep Foundation. Biochemical blood variables indicati…
GLP-2 as Beneficial Factor in the Glucose Homeostasis in Mice Fed a High Fat Diet
2015
Glucagon like peptide-2 (GLP-2) is a gastrointestinal hormone released in response to dietary nutrients, which acts through a specific receptor, the GLP-2 receptor (GLP-2R). The physiological effects of GLP-2 are multiple, involving also the intestinal adaptation to high fat diet (HFD). In consideration of the well-known relationship between chronic HFD and impaired glucose metabolism, in the present study we examined if the blocking of the GLP-2 signaling by chronic treatment with the GLP-2R antagonist, GLP-2 (3-33), leads to functional consequences in the regulation of glucose metabolism in HFD-fed mice. Compared with animals fed standard diet (STD), mice at the 10th week of HFD showed hy…
Association of obesity with proteasomal gene polymorphisms in children.
2013
The aim of this study was to ascertain possible associations between childhood obesity, its anthropometric and clinical parameters, and three loci of proteasomal genes rs2277460 (PSMA6c.-110C>A), rs1048990 (PSMA6c.-8C>G), and rs2348071 (PSMA3c. 543+138G>A) implicated in obesity-related diseases. Obese subjects included 94 otherwise healthy children in Latvia. Loci were genotyped and then analyzed using polymerase chain reactions, with results compared to those of 191 nonobese controls.PSMA3SNP frequency differences between obese children and controls, while not reaching significance, suggested a trend. These differences, however, proved highly significant (P<0.002) in the subset…
Obesity interferes with the orosensory detection of long-chain fatty acids in humans
2014
Background: The association between the orosensory detection of lipids, preference for fatty foods, and body mass index (BMI; in kg/m 2 ) is controversial in humans. Objective: We explored the oral lipid-sensing system and the orosensory-induced autonomic reflex system in lean and obese subjects. Design: Lean (BMI: 19 to ,25; n = 30) and obese (BMI .30; n = 29) age-matched men were enrolled. Their oral threshold sensitivity to linoleic acid (LA) was determined by using a 3-alternative forced-choice ascending procedure, and their eating habits were established by the analysis of 4 consecutive 24-h food-consumption diaries. The effect of brief oral lipid stimulations on plasma triglyceride [(…
Anthropometric measurements of the body composition of cancer patients determine the precise role of the body surface area and the calculation of the…
2012
The calculation of an accurate dose of chemotherapy for oncological patients reduces the possible medication errors and the toxicity of the body and so it improves the outcome of the treatment (survival). In oncological practice for the calculation of the dose of chemotherapy the human body surface area (BSA) is used. The human body surface area is determined by derived formulas, but it is not directly linked to the pharmacokinetics of the drugs. Pharmacokinetic studies have demonstrated that for the calculation of the chemotherapy dose the actual body weight should be taken into account rather than the ideal one. In the therapeutic dose determination the body fat mass has essential signifi…
Obesity alters the gustatory perception of lipids in the mouse: plausible involvement of lingual CD36. : Obesity decreases the fat preference
2013
International audience; A relationship between orosensory detection of dietary lipids, regulation of fat intake, and body mass index was recently suggested. However, involved mechanisms are poorly understood. Moreover, whether obesity can directly modulate preference for fatty foods remains unknown. To address this question, exploration of the oral lipid sensing system was undertaken in diet-induced obese (DIO) mice. By using a combination of biochemical, physiological, and behavioral approaches, we found that i) the attraction for lipids is decreased in obese mice, ii) this behavioral change has an orosensory origin, iii) it is reversed in calorie-restricted DIO mice, revealing an inverse …
Automatic bilevel ventilation in sleep-disordered breathing: A real-life experience in southern Italy
2016
Automatic bilevel ventilation (AutoBI) has been recently introduced to treat obstructive sleep-disordered breathing (SDB), but clinical experience is still limited. We revised the charts of patients treated for obstructive SDB in our sleep clinic in 2015 (n=214) to assess the frequency of trials of AutoBI ventilators (ResMed Auto25 or Respironics BiFlex), the clinical characteristics of these patients, the reason to shift from CPAP to AutoBI, and the outcome of AutoBI titration. A trial of domiciliary AutoBI was made in 44 patients (20.5%) intolerant to CPAP due to high CPAP levels (n=11) or who showed incomplete resolution of SDB on CPAP (n=33). The table reports the clinical data accordin…
Efectos de un programa de rehabilitación cardíaca fase III sobre los factores de riesgo hipertensión arterial y obesidad en personas mayores de 60 a¿…
2011
[EN] Aim To quantify time of evolution of arterial hypertension (AHT) and obesity during Phase III of the Cardiac Rehabilitation Program (CRhbP) and to assess the possible influence of the patient's characteristics on the effectiveness of the program. Study design An observational retrospective study. Patients and methods A Phase III CRhbP was applied for one year on 18 patients over 60 years of age with cardiovascular disease (CVD). Both systolic (SBP) as well as diastolic (DBP) blood pressure (BP) and abdominal circumference (AC) were measured at the start of the program, at 6 months and at 12 months. Results The decrease in BP was significant for both SBP (p-value = 0.00) and DBP (p-valu…
