An increase in visceral fat is associated with a decrease in the taste and olfactory capacity
2017
Introduction Sensory factors may play an important role in the determination of appetite and food choices. Also, some adipokines may alter or predict the perception and pleasantness of specific odors. We aimed to analyze differences in smell–taste capacity between females with different weights and relate them with fat and fat-free mass, visceral fat, and several adipokines. Materials and methods 179 females with different weights (from low weight to morbid obesity) were studied. We analyzed the relation between fat, fat-free mass, visceral fat (indirectly estimated by bioelectrical impedance analysis with visceral fat rating (VFR)), leptin, adiponectin and visfatin. The smell and taste ass…
Red blood cell distribution width is not related with inflammatory parameters in morbidly obese patients
2013
Red blood cell distribution width (RDW) is a hematological parameter that has been studied in several clinical settings and has been found to be related to both anemia and inflammatory status. As obesity is related to increased inflammatory pattern, we aimed to analyze the RDW in this setting.We determined hematological and inflammatory parameters in morbidly obese patients before bariatric surgery (n=142) and normo-weight controls (n=144).RDW was higher in patients than in controls (p0.001), along with C-reactive protein (p0.001) and fibrinogen, (p0.001) while hemoglobin (p=0.026), serum iron (p0.001), MCH (p=0.002) and MCHC (p0.001) were lower in morbidly obese patients. The logistic corr…
Hepatic and circulating levels of PCSK9 in morbidly obese patients: Relation with severity of liver steatosis
2020
Non-alcoholic fatty liver disease (NAFLD) is becoming the main cause of liver disease in Western countries, especially in morbidly obese patients (MOPs). The proprotein convertase subtilisin/kexin type 9 (PCSK9) has been recently studied because of its possible involvement in the pathogenesis of NAFLD, but its role, at least in MOPs, is still controversial. The aim of this study was to clarify the correlation between the circulating levels of the PCSK9 protein (cPCSK9) and its hepatic expression with the severity of liver damage in a population of MOPs with NAFLD undergoing bariatric surgery. PCSK9 mRNA was positively correlated with FASN, PPARγ and PPARα mRNAs, while no significant differe…
Rheological blood behaviour is not related to gender in morbidly obese subjects.
2012
To the Editor. We have read with interest the recently published article by Wiewiora et al. [7] regarding hemorheological differences related to gender in morbidly obese subjects. In this study authors found several hemorheological differences between male and female. In this sense, males showed higher blood viscosity and higher erythrocyte deformability than females and native blood viscosity correlated with several erythrocyte aggregation parameters evaluated with the Laser-Assisted Optical Rotational Cell Analyser (LORCA) [3]. In studies with small sample sizes (18 men and 20 women) there is always the risk that differences in certain variables may appear by chance or by imbalances in th…
Employment Is Associated with the Health-Related Quality of Life of Morbidly Obese Persons
2010
Published version of an article in the journal: Obesity Surgery. The original publication is available at Springerlink. http://dx.doi.org/10.1007/s11695-010-0289-6. Open Access Background We aimed to investigate whether employment status was associated with health-related quality of life (HRQoL) in a population of morbidly obese subjects. Methods A total of 143 treatment-seeking morbidly obese patients completed the Medical Outcome Study 36-Item Short-Form Health Survey (SF-36) and the Obesity and Weight-Loss Quality of Life (OWLQOL) questionnaires. The former (SF-36) is a generic measure of physical and mental health status and the latter (OWLQOL) an obesity-specific measure of emotional…
Resting energy expenditure and body composition in morbidly obese, obese and control subjects
1994
Resting energy expenditure (REE) was investigated by indirect calorimetry in relation to body composition and to different degrees of obesity in order to assess if a defective energy expenditure contributes to extra body fat accumulation. Differences were found between control subjects (group C; BMI 23 +/- 0.5 kg/m2, REE 5890 +/- 218 kJ/day; mean +/- SEM) and obese subjects (group O; BMI 34.2 +/- 0.9 kg/m2, REE 7447 +/- 360 kJ/day; P0.0001) and between group C and morbidly obese subjects (group MO; BMI 49.9 +/- 1.6 kg/m2, REE 8330 +/- 360 kJ/day; P0.0001); REE was not significantly different between groups O and MO. Body composition data were obtained by means of body impedance analysis. Ev…
The relationship between the rheological behavior of RBCs and angiogenesis in the morbidly obese
2018
OBJECTIVE The aim of this study was to investigate the relationship between red blood cell (RBC) aggregation and deformability and angiogenesis parameters in obese patients. METHODS We studied 35 obese subjects and 20 non-obese people as a control group. Angiogenesis was detected using Bio-Plex Pro Human Angiogenesis Multiplex Assays. The RBC aggregation and deformability of the red blood cell aggregation were performed by the Laser-assisted Optical Rotational Cell Analyser - LORCA. RESULTS The aggregation index and the syllectogram's amplitude were significantly higher in the obese patients, whereas the aggregation half-time (t1/2) was lower compared with the control group. The deformabili…
Anesthesiological Particularities in Bariatric Surgery
2011
Morbid obesity has become a global pandemic in recent years: 5% of the adult population of the USA are considered morbidly obese, i.e., have a BMI that exceeds 40. Every 90 seconds a US American dies of obesity and its consequences – making 1,000 people every day and 400,000 a year. This explains the dramatic rise of interest in bariatric procedures and with it in suitable anesthesiological methods.
Decreased Esophageal Sensitivity to Acid in Morbidly Obese Patients: A Cause for Concern?
2017
Background/Aims: To evaluate esophageal sensitivity to acid between morbidly obese (MO) patients and non-MO controls with abnormal esophageal acid exposure. Methods: We conducted a cross-sectional study of 58 patients: 30 MO (cases) and 28 non-MO (controls). Esophageal symptoms and esophageal sensitivity to 0.1 M hydrochloric acid solution (Bernstein test) were compared between MO and non- MO patients with a prior diagnosis of abnormal esophageal acid exposure. Results: MO patients were less symptomatic than non-MO controls (14% vs 96%; odds ratio [OR], 0.006; 95% confidence interval [CI], 0.001 to 0.075; p=0.000). MO patients were more likely to present with decreased esophageal sensitivit…
Biliopancreatic Diversion: early complications
1992
The experience and early complications in 66 morbidly obese patients who underwent biliopancreatic diversion are presented. There was one death, due to a pulmonary embolus (PE) at home on the 15th postoperative day. Postoperative complications occurred in nine patients, consisting of gastric hemorrhage (2), gastric outlet obstruction (2), non-lethal PE (1), deep vein thrombosis (1), wound dehiscence (1), and asymptomatic gastric leak (1). In addition, there were 12 superficial wound infections. Four patients required urgent reoperation for gastric hemorrhage (2), gastric outlet obstruction (1), and wound dehiscence (1). The high complication rate is believed to represent the early part of t…
