Filter by:Obesity is an increasing global public health issue. In general, tea consumption have been shown to offer benefit to obese patients. However, the potential of white tea (WT) to treat and protect from the adverse effects of obesity have not been addressed so far. The aim of this study was to examine the efficacy and impact WT consumption highest in catechins on levels of anthropometric and biochemical values in obese patients.
It has been suggested that individuals with the condition known as metabolically healthy obesity (MHO) may not have the same increased risk of developing metabolic abnormalities as their non-metabolically healthy counterparts. In addition, to date, the identification of metabolic biomarkers and microbiota underlying the MHO state is limited. In this study, our goal is to provide insight into the underlying metabolic pathways affected by obesity. To achieve this, we will compare the metabolic profile, inflammatory parameters and mitochondrial function, as well as metabolomic analysis and differential expression of microbiota in obese patients categorized as metabolically healthy vs. non healthy. In parallel, the effect of a hypocaloric diet on obese subjects' metabolism and microbiota will be assessed to approve their use in the treatment of said disorder. Specifically, we propose an observational, clinical-basic, comparative and interventional study in a population of 80 obese (BMI>35 kg/m2) patients clustered in two groups according to the presence or absence of altered metabolism (altered fasting glycemia, hypertension, atherogenic dyslipidemia). Anthropometric and clinical variables and biological samples (serum, plasma, peripheral blood cells and feces) will be collected for the determination of biochemical parameters (glucose, lipid and hormonal profile by enzymatic techniques) and protein-based peripheral biomarkers of mitochondrial function [total and mitochondrial reactive oxygen species (ROS) production, mitochondrial membrane potential, glutathione levels by static cytometry], markers of mitochondrial dynamics [Mitofusin 1 (MFN1), Mitofusin 2 (MFN2), Mitochondrial fision protein 1 (FIS1) and Dynamin-related protein 1 (DRP1) by RT-PCR and Western Blot], markers of inflammation [Interleukin 6 (IL6), Tumoral necrosis factor alpha (TNFα), IL1b, adiponectin, resistin, plasminogen activator inhibitor 1 (PAI-1), Monocyte chemoattractant protein-1 (MCP-1), caspase 1 and NLRP3 by Western Blot and technology XMAP), metabolomic assay (NMR spectroscopy and PLS-DA), as well as gut microbiota content and diversity (16S rRNA, MiSeq sequencing). Finally, we will evaluate the effect of a dietary weight loss intervention on these biomarkers.
Bariatric surgery is the most effective treatment for severe obesity, yet a significant percentage of patients achieve suboptimal results or present long-term weight regain. Given the strong association between poor outcomes and post-surgery psychological factors, it is crucial to implement post-surgical psychological interventions. This randomized controlled trial aims to compare the efficacy of a novel, cost-effective, and timely-personalized treatment delivering strategy (stepped-care) with two different intensities 1) low-intensity intervention delivered by Facebook®, and 2) high-intensity program delivered online. It is also intended to study predictors, outcome moderators/mediators, and the underlying mechanisms of weight regain. Participants' assessment will include measures of pathological eating behavior, psychological impairment, negative urgency, and emotional regulation.
Heart failure with preserved ejection fraction (HFpEF) is a common and serious complication of obesity and type 2 diabetes (T2D). HFpEF occurs when the heart muscle unable to relax efficiently to pump the blood around the body. This leads to fluid build-up, breathlessness and inability to tolerate physical exertion. People who develop HFpEF do less well because treatment options are limited. Pilot data in patients with obesity and diabetes and a small number of patients with HFpEF have shown improvements in exercise capacity and reversal of changes in the heart and blood vessels. This study will assess if this is achievable in a multi-ethnic cohort of patients with established HFpEF. A total of 102 adults will be invited and allocate by chance into two groups: either a 12-week diet or health advice on how to lose weight. The study will determine if weight loss over 12 weeks can improve heart function, symptoms and ability to exercise. Additionally, participants' views on changing their diet and how this has impacted their symptoms will be sought during the study in an optional interview. This will help guide treatments planning in the future to get maximum benefits, and to individualize support to patients from different cultural backgrounds.
This study was conducted to compare the effectiveness of care based on the "Accelerated Recovery After Surgery (ERAS) Protocol" and the traditional method in bariatric surgery and demonstrate the difference the two methods based on evidence.
The concept personalized gene-based nutrition combines genetic information with specific dietary intake that is crucial in managing obesity. Obesity experienced by adult women is generally caused by inapproriate diet and sedentary lifestyle. Variations in the fat mass and obesity-related gene (FTO) has been linked with susceptibility to obesity, but diet seems to change the relationship. A single nucleotide polymorphism (SNP) in the fat mass and obesity-associated gene (FTO) is a potent predictor of human obesity. Higher protein diets were more appropriate than standard protein diets, and frequently recommended as a weight loss plan as it prevents the loss of lean tissue mass. Nevertheless, high intakes of proteins may adversely affect metabolic functions. Multi studies have explored associated FTO polymorphisms with obesity in different populations. However, the contribution of the FTO common variants to obesity is controversial in Asian people, some studies showed rs1558902 was statistically associated with BMI, but other results reported FTO gene is not statistically associated with obesity. Given the diversity of Asian populations, the investigators generated a hypothesis whether relations between preference protein intake and FTO rs1558902 gene polymorphism exist in selected Indonesian obesity women
Importance and Purpose of the Study: Proper management of the difficult airway is an important part of preventing anesthesia-related mortality and morbidity. Difficult airways, characterized by both difficult mask ventilation and difficult intubation, are common in obese patients. Many studies have shown an association between obesity or morbid obesity and difficult intubation. We thought that in obese patients, increased subcutaneous fat tissue in the nape of the neck may restrict the head extension and cause difficult intubation and difficult mask ventilation, and the increase in the chin-nape circumference may predict difficult intubation and difficult mask ventilation. We also predicted that the ratio of neck circumference to chin-nape circumference might predict difficult intubation and difficult mask ventilation. Materials and Methods: After the approval of the ethics committee, obese patients who require tracheal intubation, undergo elective surgery, over the age of 18, with a body mass index (BMI) of more than 30 were evaluated. Patients with cervical spine anomaly, emergency procedures, known history of difficult intubation or upper respiratory tract disease, and planned awake intubation were excluded from the study. Mallampati score, mouth opening, upper lip bite test, distance between incisors, thyromental distance, sternomental distance and thyromental height were recorded. Using a tape measure, the neck circumference from the thyroid cartilage level and the chin-neck circumference from the mentum level were measured with the patient in a neutral position. The ratio of neck circumference to thyromental distance and the ratio of neck circumference to chin-nape circumference were calculated from these measurements. Mask ventilation was graded according to the method described by Han et al. After adequate muscle relaxation was achieved, tracheal intubation was performed with an appropriately sized Macintosh blade using direct laryngoscopy. Difficult intubation evaluation was performed using the Difficult Intubation Scale (IDS) based on seven variables. Results: A statistically significant relationship was found between difficult intubation and the distance between incisors, neck circumference, neck circumference / thyromental distance, neck circumference / sternomental distance, and chin-nape circumference. In the multivariate regression analysis performed with these parameters, the distance between the incisors was <4.85 cm and the neck circumference> 41.5 cm was found to be independent risk factors for difficult intubation. A statistically significant relationship was found between difficult mask ventilation and age, male gender, OSAS, neck circumference, neck circumference / thyromental distance, neck circumference / sternomental distance, neck circumference / chin-nape circumference and chin-nape circumference. In the multivariate regression analysis performed with these parameters, it was determined that male gender and neck circumference thicker than 45.5 cm were independent risk factors for difficult mask ventilation. Conclusion: The ratio of neck circumference to chin-nape circumference and chin-nape circumference are successful in predicting difficult mask ventilation in obese patients. While chin-nape circumference is successful in predicting difficult intubation in obese patients, neck circumference / chin-nape circumference is unsuccessful.
Research Question: Does 4 weeks of supplementation with 'SPM Active' lead to a statistically significant increase in plasma SPM concentration for obese human subjects? Primary Aim 1: To compare plasma SPM concentrations and immunological fitness pre- and post- oral SPM administration in the obese. - Aim 1a: To quantify plasma SPM concentrations in plasma (pg/mL), serum (pg/mL) and PBMCs before and after 4 weeks of supplementation with 'SPM Active.' The concentration of SPMs in plasma, in addition to other PUFA-derived metabolites that share the same enzymatic pathways as SPMs, will be established at baseline and post-intervention using mass spectrometry-based metabololipidomics. - Aim 1b: To measure in vitro antibody responses of B cells in PBMC pool with in vitro stimulation and cytokine production before and after 4 weeks of supplementation with 'SPM Active.' In addition, researchers will quantify the relative abundance of differing immune cell populations.

It was demonstrated that acute dietary supplementation with GSE reduced arterial blood pressure via reduction in Q in obese individuals. However, no studies have investigated the chronic effects of dietary GSE supplementation on hemodynamic responses during exercise. Given the fact that obesity is associated with an impaired function of eNOS, the effect of chronic dietary GSE supplementation on abnormal blood pressure response to exercise and aortic stiffness (AoS) needs be elucidated. Thus, it is hypothesized that GSE decreases systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), Q, and aortic stiffness at rest and during exercise. This study would determine that this supplementation may be used as a non-pharmacological intervention to prevent incident hypertension and cardiovascular events during exercise via enhanced endothelial function.
