Routine laboratory lipid assays include simple measurements of total cholesterol, triacylglycerols and HDL. However, lipids are a large group of compounds involved in many metabolic pathways, and their alterations may have serious health consequences. In this study, we used (1)H NMR to analyze lipids extracted from sera of 16 obese patients prior to and after bariatric surgeries. We observed a post-surgery decrease in serum concentrations of lipids from various groups. The hereby presented findings imply that (1)H NMR is suitable for rapid, simple and non-invasive detection of lipids from 30 structural groups, among them triacylglycerols, phosphatidylcholine, phosphatidylethanolamine, sphingomyelin, total phospholipids, total, free and esterified cholesterol, total and unsaturated fatty acids...

BACKGROUND AND PURPOSE: Currently, there is no guideline or standard of practice for performing the psychiatric/psychological evaluation that is a requirement for approval for bariatric surgery. The Readiness to Change for Bariatric Surgery Assessment Tool (RCB-SAT) establishes a means for psychiatric evaluators to objectively assess the patient's cognition, beliefs, and motivation around the bariatric diet and lifestyle changes. Development of a clinical decision-making tool for assessing readiness to change in bariatric patients will be useful regarding The Strategic Plan for NIH Obesity Research...

Morbid obesity is a lifelong disease, and all patients require complementary follow-up including nutritional surveillance by a multidisciplinary team after bariatric procedures. Pancreatic exocrine insufficiency (PEI) refers to an insufficient secretion of pancreatic enzymes and/or sodium bicarbonate. PEI is a known multifactorial complication after upper gastrointestinal surgery, and might constitute an important clinical problem due to the large number of bariatric surgical procedures in the world. Symptoms of PEI often overlap with sequelae of gastric bypass, making the diagnosis difficult...

OBJECTIVE: Bariatric surgery appears as the most efficient therapeutic alternative in morbidly obese patients. In addition to its efficiency to decrease body weight, it also improves metabolic complications associated to morbid obesity, including dyslipidemia. Although the cholesterol-lowering effect varies with the bariatric procedures, the underlying molecular mechanisms remain poorly defined. This study aims to assess the consequence of both restrictive (sleeve gastrectomy; SG) and malabsorptive (Roux-en-Y gastric bypass; RYGB) procedures on cholesterol metabolism in mice...

PURPOSE OF REVIEW: Although childhood obesity has leveled off in the last decade, 'severe obesity' continues to be on the rise. Various genetic, environmental and hormonal factors contribute to obesity. This article reviews the most current understanding of obesity's multifactorial origin and recent recommendations for its management in childhood and adolescence. RECENT FINDINGS: Epigenetics plays a key role in transmitting obesity risk to offspring. Single-nucleotide polymorphisms at genetic loci for adipokines and their receptors are associated with obesity...

Obesity is a chronic disease with serious consequences and although lifestyle modification is considered first line treatment, it is often ineffective, especially in the long term. Relatively few people with obesity will undergo the most effective currently available treatment of bariatric surgery. Pharmacotherapy can bridge the gap between lifestyle modification and surgery, but many monotherapies have only modest efficacy or require high doses with unacceptable side effects. As with many other areas of medicine, combination therapy is now becoming accepted as a way of optimising efficacy for weight management, whilst minimising adverse effects...

BACKGROUND: Paradoxically, advances in anti-retroviral therapy that has increased survival for patients with human immunodeficiency virus (HIV) have resulted in greater numbers of HIV+ patients developing other chronic diseases, including obesity. Little comparative literature exists detailing perioperative or metabolic outcomes of bariatric surgery in the HIV+ population compared to HIV negative (HIV-) controls. METHODS: This is a retrospective case-control study with both HIV+ (case) and HIV- control patients...

Morbid obesity may affect several body systems and cause ill effects to the cardiovascular, hepatobiliary, endocrine, and mental health systems. However, the impact on the pulmonary system and pulmonary function has been debated in the literature. A systematic review and meta-analysis for studies that have evaluated the impact of bariatric surgery on pulmonary function were pooled for this analysis. PubMed, Cochrane, and Embase databases were evaluated through September 31, 2016. They were used as the primary search engine for studies evaluating the impact pre- and post-bariatric surgery on pulmonary function...

PURPOSE OF REVIEW: Reduced energy intake, resulting from favourable changes in eating behaviour, is the predominant driver of weight loss following bariatric surgery. Here we review the most recent studies examining the impact of Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy, the two most common bariatric procedures, upon eating behaviour and the suggested underlying biological mechanisms. RECENT FINDINGS: Following RYGB or sleeve gastrectomy, most people report subjective changes in appetite, taste and food preference, with decreased high-fat preference most commonly reported...

There is an epidemic of pediatric obesity in the United States. In most cases, there is an excess in the amount of calories consumed, compared with the amount of calories expended. Numerous body systems are affected by pediatric obesity, with complications varying between boys and girls. Behavioral, genetic, and environmental factors affect the ability of children to avoid becoming obese. Primary care physicians should screen for obesity in children as much as possible. Associated risk factors for obesity should be uncovered...

Obesity and its associated comorbidities entail a significantly increased cardiovascular mortality. Therefore, approaching obesity control must include among its aims the reduction of the associated comorbidities and the higher cardiovascular mortality risk and not only weight loss. Many observational studies indicate that bariatric surgery (BS) is associated with a better long-term survival than standard care. Furthermore, in general, these epidemiological studies included patients who underwent gastric bypass (GB), not biliopancreatic diversion/duodenal switch (BPD/DS), so the potential additional benefit of this latter technique remains unknown...

Towards the end of the 20th century, the number of subjects with diabetes and obesity rose exponentially. The discoveries of insulin- and appetite-modulating chemical signals, including glucagon-like peptide-1 (GLP-1), secreted from the gastrointestinal system, led to development of a new group of drugs which now are being used for glucose-lowering therapy and weight loss. Understanding of the physiology of gut derived signals and their pathophysiologi-cal importance requires accurate measurements of their circulat-ing levels...
