Filter by:Stress can lead to obesity via inappropriate eating. In addition, obesity is a major stress factor. Furthermore, stressed people are also those who have the greatest difficulties to lose weight. The relationships between obesity and stress are biological via the action of stress on the major hormones regulating appetite (leptin, ghrelin). International recommendation proposals suggest to implement stress management programs in obesity for a sustainable weight loss. Moreover, stress and obesity are two public health issues. Among the multiple physical and psychological consequences of stress and obesity, increased mortality and cardiovascular morbidity seem the main concern. Many spa resorts are specialized in the treatment of obesity in France but actually no thermal spa proposes a specific program to manage stress in obesity. The main hypothesis is that a thermal spa residential program (21 days) of stress management in obesity will exhibit its efficacy through objective measures of well-being and cardiovascular morbidity.
Background There has been much interest in the relationship between the types of gut microbiota and the development of obesity in recent years. It has been reported that the proportions of Firmicutes and Bacteroidetes differ between obese and normal weight human subjects. Human intestinal microbiota compositions have been found to be associated with long-term dietary habits and lifestyle. However, an increasing number of researches show that intestinal microbiota composition may be affected after short-term diet intervention. Importantly, obesity and metabolic problems play important roles in morbidity and mortality of schizophrenia patients. Human intestinal microbiota compositions related with obesity may impact the heath of this population. Therefore, we searched current advances about the connection of obesity, intestinal microbiota compositions, and diet in schizophrenia to conduct a clinical research focus on the effect of high fiber diet on the intestinal microbiota of schizophrenia patients with central obesity. Method We will investigate in a 4-week intervention whether consumption of dietary fiber supplement(Inulin) affect the microbiota composition in schizophrenia inpatients with central obesity. Fecal samples from participants before and after the intervention will be processed for the microbiota analysis.
In the study of a population of severe asthmatics, not controlled despite the treatment conducted, it was possible to evidence 5 phenotypic groups of patients. According to the refractoriness of the response to treatment, severe asthma may be phenotype in some distinct groups.Other prospective study found a large proportion of severe asthmatics with persistent airway obstruction, despite optimized treatment and systematic follow-up. Small airway involvement and remodelling, characterized by bronchial muscle thickening, appear to be the main culprits for asthma severity and persistent obstruction in this population.A point of interest in the severe asthmatics cohort was the vast majority were female and there were a considerable number of obese. Recent reviews show that the more consistent division of phenotypes in patients with severe asthma is still based on 3 previously described criteria (presence of atopy, eosinophilia and age of onset of asthma) and a more recent criterion for the presence of multi-comorbidities. Heterogeneity is the rule, the presumption of a natural evolution of gravity is not confirmed and the overlap of clusters is frequent. The stability and natural history of the phenotypes is poorly understood, postulating that the inflammatory activation of the severe asma is multifactorial and may resemble that described in the oncology literature.To date, there are no markers that allow prediction of lung evolution of most patients with severe asthma, and which patients are at greater risk of developing persistent or accelerated loss airflow or lung function, factors determining the severity of asthma. It is also unclear whether and how much phenotype-based treatment impact on disease control and prognosis. Future studies will be instrumental in defining how and why. These phenotypes are evolving, leading to the disabling characteristics of severe asthma and what may be the more effective therapeutic approaches for these patients. Since the initiated research group from 2006 has an extensive clinical, functional, inflammatory, tomographic and morphological evaluation of a cohort of patients with severe asthma, the ideal scenario exists to advance the understanding and investigation of the evolution of this rare disease through standardized follow-up.
Obesity is a complex metabolic state at which many pathophysiological pathways seem to interfere, like imbalance of autonomic nervous system, as well as renin-angiotensin-aldosterone system (RAAS) activation. Latest studies have shown that the increase of peripheral fat in obese patients, alongside with the increase of P-450 aromatase leads to hyper-aldosteronism, which results to increased sodium intake and rise of blood pressure. The present study aims to investigate the potential superiority of an aldosterone antagonist based therapy (eplerenone) over the renin-angiotensin antagonists (ARBs) (valsartan) based therapy in hypertensive obese patients regarding reduction of blood pressure (office, home and ambulatory) over a 24-week period.
Red light laser therapy using 635nm red light laser technology has previously been shown to cause lipolysis in subcutaneous fat as a non-surgical method to promote weight loss and body contouring. This study hypothesizes that red LED light therapy using 650nm red light LED (light emitting diode) technology produces similar results to the laser device (red LASER 635nm) when preformed using a specified treatment protocol.
Action research has been developed in this direction in order to use a tool to identify food disorder behavior among obese youths in their neighborhoods and social centers in vulnerable neighborhoods of Marseille, with the aim of a multi-professional therapeutic management (psychosocial support, theater) and a specialized orientation. This program consists of the participation of each patient recruited in collective workshops. A total of 60 patients considered. Our hypothesis lies in the fact that for young people to participate in an adapted device, taking into account the global needs of young people and their entourage, would limit the deleterious effects of obesity and promote the young person's autonomy and allow him to be a actor in the request for care. The project's objective is to provide support in the form of workshops with patients identified by the Marseille Hospitals Public Assistance Health Center as obese children and adolescents, in a precarious situation; to identify the presence of binge eating disorders and evaluate the impact of participation in these workshops on subsequent management by highly specialized professionals in food disorder behavior.
Neuraxial anaesthesia can be more difficult and associated with more complications if the patient's bony landmarks are difficult to palpate. They are more likely to be difficult to palpate if a patient has a high Body Mass Index (BMI), (>30kg/m2). The depth that the spinal or epidural needle must be inserted is usually longer in these patients with high BMIs. We wish to palpate the backs of at least 100 such patients to see how many of them have impalpable bony landmarks. We then wish to use ultrasound to measure the distance from skin to the posterior epidural complex to discover if this length is longer than the standard needle length. If it is longer in the majority of people we study, we will recommend changing standard practice to start using a longer needle for all first attempts at neuraxial anaesthesia in this patient population.
The correlation between metabolic syndrome and carotid artery stenosis is well established. The purpose of this study is to evaluate the relationship between morbid obesity and carotid artery stenosis.
Obesity and type 2 diabetes mellitus (T2DM) are major global health concerns as they commonly co-occur and are associated with significant morbidity, mortality, and health care expenditures. The Indigenous (First Nations, Metis and Inuit) population bears a disproportionate burden of T2DM in Canada. The prevalence of obesity among Indigenous individuals is approximately 31.2% compared to 18.6% for the non-Indigenous population. In 2011, 16.7% of Manitoba's population, or four times the Canadian average, identified as Indigenous. At the same time, prevalence of T2DM in Manitoba is on the rise. Bariatric surgery is an effective treatment modality for the improvement and resolution of T2DM in patients who are obese. We aim to compare the effectiveness of bariatric surgery with conventional medical treatment in treating metabolic diseases in Indigenous people; the findings of which will assist in future treatment and program planning. Our objective is to determine whether Manitoba's urban Indigenous population will achieve better diabetic control and improved rates of remission of T2DM with bariatric surgery compared to best diabetic medical care.
Background: Obesity is one of the most important diseases around the globe; with a continuous increase and public health concern. Current treatments present some limitations. Craving is a symptom usually noticeable and has been described as a "strong desire or urge to use", especially with foods. The vagus nerve and its relations to the neurocircuitry of the reward system play essential roles in food intake regulation and this can be done transcutaneously trough the auricular branch of the vagus nerve (taVNS). Based on the neurobiology of food craving and on the initial data on taVNS demonstrating safety and efficacy in open-label and randomized sham controlled trials, the investigators propose the first randomized, sham controlled, triple-blind trial on taVNS for food craving in obesity. Methods: This will be a two-arm, triple-blinded, randomized controlled trial with 54 subjects with food craving assigned to either: 1) a 10-session treatment protocol of real taVNS, or 2) a 10-session treatment protocol of sham taVNS, besides qualitative electroencephalogram (qEEG) and heart rate variability (HRV). Participants will be evaluated for primary outcome measures (Food Craving Questionnaire - State [FCQ-S] and Food Craving Questionnaire - Trait [FCQ-T]) before and after intervention, with a follow-up visit of 30 days after the end of treatment. A comparison between sham and active groups will be performed in three occasions [baseline (T1), at the end of the stimulation protocol (T2) and 30 days after the last day of stimulation (T3)]. Discussion: Given the epidemiological situation and economic and social burdens, the possibility of modulating the reward system neurocircuitry trough the vagus nerve with an easy-to-use, low-cost, safe and potential at-home use could represent a breakthrough in treating obesity. The investigators hypothesized that food craving in obese individuals would decrease at least 50%, as well as their intake of high fat, high sugar and processed food, commonly described as palatable foods. Beyond that, the investigators expect that these individuals would improve anxiety symptoms.
