Abstract
BACKGROUND Obesity results from interactions between environmental factors, lifestyle, and genetics. In this scenario, nutritional genomics and nutrigenetic tests stand out, with the promise of helping patients avoid or treat obesity. This narrative review investigates whether nutrigenetic tests may help to prevent or treat obesity. Scientific studies in PubMed Science Direct were reviewed, focusing on using nutrigenetic tests in obesity. The work showed that few studies address the use of tools in obesity. However, most of the studies listed reported their beneficial effects in weight loss. Ethical conflicts were also discussed, as in most countries, there are no regulations to standardize these tools, and there needs to be more scientific knowledge for health professionals who interpret them. International Societies, such as the Academy of Nutrition and Dietetics and the Brazilian Association for the Study of Obesity and Metabolic Syndrome, do not recommend nutrigenetic tests to prevent or treat obesity, especially in isolation. Advancing nutrigenetics depends on strengthening three pillars: regulation between countries, scientific evidence with clinical validity, and professional training.

Abstract
Obesity exerts both direct and indirect effects on gastrointestinal function. From physical effects of central adiposity on intragastric pressure resulting in higher incidence of reflux to dyslipidemia and effects on gallstone disease, the gastrointestinal manifestations of obesity are wide-ranging. Of particular emphasis is the identification and management of non-alcoholic fatty liver disease including non-invasive assessment and lifestyle and pharmacologic interventions for patients with non-alcoholic steatohepatitis. Additional focus is on the impact of obesity and western diet on intestinal disorders and colorectal cancer. Bariatric interventions involving the gastrointestinal tract are also discussed.

A Comprehensive Review on Bariatric Endoscopy: Where We Are Now and Where We Are Going. MEDICINA (KAUNAS, LITHUANIA) 2023; 59:medicina59030636. [PMID: 36984637 PMCID: PMC10052707 DOI: 10.3390/medicina59030636] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/05/2023] [Revised: 03/14/2023] [Accepted: 03/18/2023] [Indexed: 03/30/2023]
Abstract
Background: Obesity is a chronic disease that impairs quality of life and leads to several comorbidities. When conservative therapies fail, bariatric surgical options such as Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) are the most effective therapies to induce persistent weight loss. Over the last two decades, bariatric endoscopy has become a valid alternative to surgery in specific settings. Primary bariatric endoscopic therapies: Restrictive gastric procedures, such as intragastric balloons (IGBs) and endoscopic gastroplasty, have been shown to be effective in inducing weight loss compared to diet modifications alone. Endoscopic gastroplasty is usually superior to IGBs in maintaining weight loss in the long-term period, whereas IGBs have an established role as a bridge-to-surgery approach in severely obese patients. IGBs in a minority of patients could be poorly tolerated and require early removal. More recently, novel endoscopic systems have been developed with the combined purpose of inducing weight loss and improving metabolic conditions. Duodenal mucosal resurfacing demonstrated efficacy in this field in its early trials: significant reduction from baseline of HbA1c values and a modest reduction of body weight were observed. Other endoscopic malabsorptive have been developed but need more evidence. For example, a pivotal trial on duodenojejunal bypasses was stopped due to the high rate of severe adverse events (hepatic abscesses). Optimization of these more recent malabsorptive endoscopic procedures could expand the plethora of bariatric patients that could be treated with the intention of improving their metabolic conditions. Revisional bariatric therapies: Weight regain may occur in up to one third of patients after bariatric surgery. Different endoscopic procedures are currently performed after both RYGB and SG in order to modulate post-surgical anatomy. The application of argon plasma coagulation associated with endoscopic full-thickness suturing systems (APC-TORe) and Re-EndoSleeve have shown to be the most effective endoscopic treatments after RYGB and SG, respectively. Both procedures are usually well tolerated and have a very low risk of stricture. However, APC-TORe may sometimes require more than one session to obtain adequate final results. The aim of this review is to explore all the currently available primary and revisional endoscopic bariatric therapies focusing on their efficacy and safety and their potential application in clinical practice.

Abstract
Recent insights into the pathophysiologic underlying mechanisms of obesity have led to the discovery of several promising drug targets and novel therapeutic strategies to address the global obesity epidemic and its comorbidities. Current pharmacologic options for obesity management are largely limited in number and of modest efficacy/safety profile. Therefore, the need for safe and more efficacious new agents is urgent. Drugs that are currently under investigation modulate targets across a broad range of systems and tissues, including the central nervous system, gastrointestinal hormones, adipose tissue, kidney, liver, and skeletal muscle. Beyond pharmacotherapeutics, other potential antiobesity strategies are being explored, including novel drug delivery systems, vaccines, modulation of the gut microbiome, and gene therapy. The present review summarizes the pathophysiology of energy homeostasis and highlights pathways being explored in the effort to develop novel antiobesity medications and interventions but does not cover devices and bariatric methods. Emerging pharmacologic agents and alternative approaches targeting these pathways and relevant research in both animals and humans are presented in detail. Special emphasis is given to treatment options at the end of the development pipeline and closer to the clinic (ie, compounds that have a higher chance to be added to our therapeutic armamentarium in the near future). Ultimately, advancements in our understanding of the pathophysiology and interindividual variation of obesity may lead to multimodal and personalized approaches to obesity treatment that will result in safe, effective, and sustainable weight loss until the root causes of the problem are identified and addressed.

Abstract
BACKGROUND A prospective case-matched study was conducted to compare the safety and efficacy of endoscopic intragastric botulinum toxin-A (EIBT) versus endoscopically planned gastric balloon (EPGB), as a treatment for obesity. METHODS A total of 176 patients (matched for age and sex) were equally divided to undergo EIBT (n = 88) or EPGB (n = 88). Patients who received EIBT were restricted to a body mass index (BMI) of 25 to 35 kg/m2, whereas a BMI >25 kg/m2 was allowed in the EPGB group. The main measured outcomes were weight loss, procedure duration, complications, early satiety, and quality of life (QoL). RESULTS The patients were followed up for a mean of 6 months. The mean weight loss was greater in the EPGB group than in the EIBT group (15.6 kg vs. 9.3 kg, P < 0.001). However, the percentage excess weight loss and the satiety score were greater in the EIBT group (59.1% vs. 42.2%, P < 0.001; and 3.5 vs. 2.3, P < 0.001) respectively. The procedure duration was shorter for EIBT patients (10 min vs. 15 min, P < 0.001). The postoperative complication rate recorded in the EPGB group was significantly higher (30% vs. 9%, P = 0.001). Adverse symptoms lasted longer in EPGB (5.2 days vs. 0.7 days, P < 0.001). Both groups enjoyed similar improvements in QoL. CONCLUSION EIBT is a safe and effective treatment for mild obesity. Although the weight loss was greater in the EPGB group, the percentage excess weight loss, procedure duration, postoperative complications, and symptom duration were significantly better in the EIBT group. QoL improvement was comparable between the two groups.

Abstract
Nowadays, non-alcoholic fatty liver disease is one of the first causes of liver transplant worldwide; many efforts have been done to find the perfect drug for this multifactorial disease. Presently we just have a few drugs that could be used in specific and limited clinical scenarios. Current evidence suggests that bariatric endoscopic and surgical therapies could be strategies with optimal outcomes, with high impact in quality of life, decrease of cardiovascular risk, and improvement in metabolic profile, despite being considered expensive procedures. This review proposes to consider these therapies early together with liver fibrosis evaluation, with long term cost-effectiveness benefits in the absence of response to lifestyle modifications and pharmacological treatments.
