Filter by:Prevalence rates of childhood obesity have reached alarming levels. As childhood obesity may already be associated with serious comorbidities, obese adolescents are at significantly higher risk for obesity and increased morbidity and mortality during adulthood. Combined lifestyle interventions, which include regular physical activity and dietary restriction, have been shown to result in most significant improvements in cardiovascular function and their associated factors in the pediatric and adolescent population with obesity. The aim of this study is to investigate the effects of a combined exercise and diet intervention on cardiovascular function and their associated factors in obese children.
The main purpose of this Phase 2 double blind, placebo controlled crossover clinical study is to demonstrate the efficacy and safety of CXA-10 in obese adult asthmatics. Obesity induces a chronic systemic inflammatory state characterized by impaired adipokine signaling, pro-inflammatory cytokine responses, inflammatory cell activation and enhanced generation of oxidative inflammatory mediators. This impacts the lung, increasing the severity of asthma and its exacerbations. This research will evaluate how a synthetic nitro-fatty acid (CXA-10, 10-nitro-octadec-9-enoic acid) suppresses the systemic and airway inflammation that contributes to the obese asthmatic phenotype. Current data support the pleiotropic signaling actions of CXA-10 to induce adaptive signaling actions that beneficially modulate adipokine and cytokine expression and inhibit systemic and pulmonary inflammation. The investigators hypothesize that CXA-10 induced signaling responses will alleviate obesity-related airway hyperreactivity in obese adult asthmatics.
The objective of this study is to demonstrate the ease of deployment of a novel magnetically-controlled ingestible weight loss microcapsule* and the functionality of the magnetically controlled inflation of the balloon within the stomach.
The opioid consumption has exploded in the western world, and for some patient populations such as obese patients, patients with sleep apnoea or patients undergoing cancer treatment, opioid-sparing/ opioid-free strategies could have positive effects on outcomes. Studies suggest that opioids could have opioid-induced immunosuppression, induce chronic post-operative pain syndrome and hyperalgesia in addition to the more well-known side effects such as respiratory depression, nausea, bladder, and bowel dysfunction. Hence, new studies are needed on the impact of person-centered care programs that combine pharmaceutical and non-pharmaceutical strategies to reduce the adverse short and long-term effects of opioid therapy. The overall aim is to evaluate the short-, medium- and long-term effects of opioid-free care pathways with or without person-centred care compared to conventional opioid-based treatment in patients undergoing obesity surgery. Specific aims 1. Determine the effects of opioid-free care with or without person-centred care compared with conventional opioid-based general anaesthesia on the cognitive and physical quality of recovery after surgery up to 24 months after surgery (short-term: postoperative to discharge, medium-term: 14 days, 3 months, long-term: 6 months, 12 months and 24 months). 2. Describe the clinical monitoring trend regarding nociceptive response intraoperatively between opioid-free and conventional care. 3. Map the impact of opioid-free anaesthesia (with and without person-centred care) on the usage of opioids up to 24 months after hospital discharge. 4. Explore the patients' experience of quality of life, self-efficacy and recovery after surgery in opioid-free care with or without person-centred care during the first year post-surgery. The aims will be evaluated by a prospective, randomized, non-blinded, non-commercial multi-centre study (Nov 2018-Dec 2022) approved by the Swedish Medicines Agency (EudraCT 2017003830-97) and the ethical review board (DNR 1006-17).
Obesity is a public health problem, given its prevalence (15% in France in 2012, Obépi survey) but also by the complications that it generates. We were firstly, intersted in bone mineral density during obesity. We were able to confirm in an observational study that BMD (Z-score)was augmented. We also showed, for the first time, that this increase in Z-score was dependent on sex, severity of obesity and age but also bone site. If the increase in BMD at the level of the bearing zones seems logically to be explained by the hypothesis that the mechanical stresses have an osteogenic effect on the bone tissue, the latter can not in any way respond to the concomitant increase in BMD at non-bearing areas such as the radius.These results suggest that changes in certain systemic compounds induced by obesity may interfere with bone metabolism. recent data also suggest a change in the concentration of pro-glucagon peptides (GLP-1, glicentin, glucagon, etc.) in obese subjects and in bariatric surgery). Although body composition and its variation after surgery could be largely involved in the modification of these peptides, no data on these potential relationships is currently available. However, no data are available for baseline body composition and weight loss data. Finally, 80% of obesity is associated with insulin resistance, a key mechanism in the pathophysiology of type 2 diabetes. A metabolically healthy obesity phenotype is described, although the definition criteria are not consensual.The evolution of this phenotype with aging and with the duration of evolution of obesity is not well described. Our goal is to create a database of weight-bearing patients in the care setting and to determine the "hormonal dialogue" between peripheral (muscular and adipose) and bone tissues, which may be associated with changes in body composition during obesity and aging, and that according to sex.
Obesity has increased to alarming levels in the world. Currently it is estimated that it occurs in a third of the world's population and it is expected that by 2030, 20% of the world's adult population will suffer from obesity and 38% will be overweight, and it is important to highlight that Mexico is among the first in obesity in adults and children. Obesity leads to the development of diseases such as diabetes mellitus type 2, dyslipidemias, metabolic syndrome, heart problems, among others. The treatment for obesity in the first instance are changes in lifestyle, changes in diet and exercise that have shown, in most patients, have little long-term adherence. There are also drugs that promote weight loss by modifying the appetite or absorption of macronutrients. Dapagliflozin plus metformin XR is a medicine composed with an oral antidiabetic of the group of inhibitors of SGLT2 that has shown to have significant side effects in the weight reduction and visceral adiposity in people with obesity and in patients with diabetes mellitus type 2, it is also composed with metformin which also has effects on weight loss in people with and without type 2 diabetes mellitus. For these reasons, evaluating this compound drug in people with obesity could provide high impact information as a complement for the treatment of this condition when compared to the effects produced by monotherapies.
Postmenopausal women are at a risk of excessive weight gain, bone loss, hypertension, and metabolic syndrome. Obesity-induced chronic low-grade inflammation is initiated by excess nutrients in metabolic cells. Recent studies have indicated tocotrienols (one kind of vitamin E, a potent antioxidant) supplement may be good for mitigating negative impacts of obesity in postmenopausal women. The purpose of the study is to examine the effect of 24-week tocotrienols on obesity-associated outcome measurements in postmenopausal women. The investigators will enroll 60 qualified women at the start of the study and randomly assigned to no tocotrienols (placebo) or tocotrienols group for 24 weeks. Obesity-associated measurements will be recorded using blood, urine, adipose tissue, and fecal samples. All data will be analyzed statistically.
In this nationwide multi center study the investigators combine the low dose chest CT scan data with QCT technology, to measure the BMD of spine, VAT and liver fat in the health check subjects. The aim of this study is to evaluate the performance of QCT in the health check field, and further to evaluate the prevalence of osteoporosis, obesity and liver steatosis in health check population across China.
Data about human cardiac mitochondria are cruelly lacking in the literature. However, damages of the activity of these organelles are often the source of abnormal cardiac function in several pathologies. The purpose of this study is to develop a model of purified human cardiac mitochondria, to verify the purity of these organelles and to validate the authenticity of their function in acute endocarditis and obesity, two situations known to alter their activity. Animal studies have shown that microbial infection reduced mitochondrial metabolism whereas obesity increases it. The investigator's hypotheses are the following: 1) acute endocarditis, a form of cardiac microbial infection, reduces the function of human cardiac mitochondria; 2) obesity (body mass index > 30) activates the metabolism of human cardiac mitochondria.
Neuraxial ultrasonography has been shown a safe and effective technique to enhance the overall success rate of lumbar puncture and reduce the number of injection attempts. However, the current blind palpation landmark technique is known to be highly inaccurate and may increase the risk of multiple insertion attempts, patient suffering and complication rates such as spinal cord injury. Various clinical studies have confirmed the effectiveness of ultrasound imaging compared with the traditional palpation method. However, none of the present system can achieve real-time guidance. The overall aim of this proposal is to develop an ultrasound guided automated spinal landmark identification with real-time neuraxial needle insertion system (uSINE) to improve patient safety and efficacy of neuraxial procedure needle insertion success. This will be achieved in 4 phases of technology development and clinical trial phases. The investigators will recruit 20 subjects in a prospective cohort study to investigate the spinal needle first attempt success rate as a clinically relevant outcome. The secondary aim is to develop an automated spinal landmark identification algorithm using image processing to identify spinal landmarks in 50 obese patients. Third phase objective will be to obtain clinical data, and evaluation and annotation of the clinical data of spinal ultrasonography in 65 obese patients (BMI > 30kg/m2), whereas the fourth phase will measure the uSINE identification accuracy and first-attempt puncture success rate of uSINE in a clinical study of 65 obese patients (BMI > 30kg/m2).
