Abstract
PURPOSE OF REVIEW This review explores characterizing candidates for obesity treatments including pharmacotherapy, endoscopic bariatric therapies, and metabolic bariatric surgery (MBS), focusing on established clinical parameters for diagnosing obesity beyond body mass index alone. RECENT FINDINGS Existing literature primarily provides rates for fat mass percentage (i.e., a marker for adiposity quantity), waist circumference (i.e., a marker for adiposity distribution), and C-reactive protein levels (i.e., a marker for adiposity functionality) among obesity treatment candidates. Limited data on abnormal values and sex-based differentiation exist. The literature indicates high central-tendency measures for fat mass percentage and waist circumference, while C-reactive protein levels vary. Data on the Edmonton Obesity Staging System (i.e., a marker for adiposity-related disease severity) is predominantly available for MBS candidates. Future studies in obesity interventions should improve screening and diagnosis of obesity by incorporating sex-specific considerations and providing abnormal value rates for measurements to enhance understanding of patients' characteristics.

Evaluating Weight Loss Efficacy in Obesity Treatment with Allurion's Ingestible Gastric Balloon: A Retrospective Study Utilizing the Scale App Health Tracker. Clin Pract 2024; 14:765-778. [PMID: 38804393 PMCID: PMC11130893 DOI: 10.3390/clinpract14030061] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2024] [Revised: 04/18/2024] [Accepted: 04/29/2024] [Indexed: 05/29/2024] Open
Abstract
Obesity represents a growing public health concern, affecting more than 15% of the global adult population and involving a multi-billion market that comprises nutritional, surgical, psychological, and multidisciplinary interventions. The objective of this retrospective study was to evaluate the short-term efficacy and body weight measurements associated with differing levels of physical activity following the use of Allurion's ingestible gastric balloon that was designed to increase feelings of fullness and decrease food consumption, being naturally eliminated after approximately 16 weeks. This study involved 571 individuals who qualified for the intervention for being older than 20 years with a body mass index (BMI) of 27 kg/m2 or more. Utilizing the Scale App Health Tracker and Allurion's smartwatch, this study was able to track vital signs and physical activity in real time. The participants had an average initial BMI of 34.1 kg/m2 and a median age of 41 years. Notable outcomes were observed in both study groups, "Less Active" and "More Active", which were classified by achieving less or more than a median number of 8000 daily steps. Specifically, body fat percentage saw a reduction from 33.1 ± 9.4 to 28.3 ± 10.2 in the less active group and from 32.2 to 27.5 in the more active group, with both groups achieving statistical significance (p < 0.001). Additionally, there was a significant reduction in average weight, dropping from 98.2 ± 22.8 kg to 84.6 ± 19.3 kg in the less active group and from 97.7 ± 21.0 kg to 82.1 ± 22.9 kg in the more active group (both p < 0.001). Interestingly, those in the more active group also experienced a significant increase in lean mass compared to their less active counterparts (p = 0.045), although no substantial differences in weight loss, BMI reduction, and total body fat decrease were observed between the two groups. This investigation confirms the hypothesis that Allurion's ingestible gastric balloon significantly reduces weight in the short term and enhances several physical health metrics, demonstrating effectiveness as an autonomous method for challenging weight management, regardless of the level of daily physical activity.

Abstract
PURPOSE OF REVIEW To summarize research from the last 5 years on the effects of weight loss treatments, including lifestyle changes, anti-obesity medications, and bariatric procedures on cardiovascular disease (CVD) risk factors and CVD outcomes in adults. RECENT FINDINGS This narrative review includes and summarizes the contemporary evidence of the effects of these different weight loss approaches individually. A literature search was performed using the key words obesity, weight loss, CVD, cardiometabolic, and risk factors and included key clinical trials from the past 5 years. Obesity management through weight loss is associated with improvements in CVD risk factors, such as improved blood pressure, lipid profiles, and glycemic control, with greater weight loss leading to greater improvements in CVD risk factors. Bariatric surgery is associated with greater weight loss than the other procedures and treatments for obesity, and for this, and possibly for other reasons, it is associated with greater reductions in CVD outcomes and mortality. Obesity is an independent risk factor and modulator of other CVD risk factors, and thus, treatment of obesity should be an integral part of management strategies to reduce CVD risk. Future trials and real-world studies of longer duration are needed to inform providers and patients on how to individualize the approach to modifying risks of cardiometabolic disorders through obesity management.

Abstract
INTRODUCTION: Endoscopic bariatric and metabolic therapies can potentially reproduce similar gastric and small intestinal anatomic and physiologic manipulations as Roux-en-Y gastric bypass. This proof of concept animal study was aimed to assess the feasibility, safety, efficacy, and impact on gastrointestinal physiology of combined intragastric balloons (IGB) and duodenal-jejunal bypass liner (DJBL) for the treatment of obesity. METHODS: Five Ossabaw pigs were fed a high-calorie diet to develop obesity and were randomly assigned to receive IGB or DJBL in sequence. The weight gain rate was calculated. Fasting and postprandial blood samples were drawn before any intervention (serving as the baseline group) and 1 month after second device insertion (serving as the combination group) to measure gut neurohormonal changes and metabolic parameters. RESULTS: Four pigs successfully received a sequential device insertion. One pig developed duodenal sleeve prolapse that was spontaneously resolved. One pig was early terminated because of developing a central line infection. The rate of weight gain in the combination group (0.63 ± 1.3 kg/wk) was significantly lower than the baseline group (1.96 ± 2.17 kg/wk) and numerically lower than after insertion of the IGB (1.00 ± 1.40 kg/wk) or the DJBL (0.75 ± 2.27 kg/wk) alone. A trend of higher postprandial glucagon-like peptide-1 was observed in the combination group compared with the baseline group. DISCUSSION: A combination of IGB and DJBL is feasible and well tolerated. A strategy of sequential use of these devices might offer a synergistic approach that can enhance weight loss and metabolic outcomes.

Abstract
BACKGROUND AND AIMS Nonalcoholic fatty liver disease, now renamed metabolic dysfunction-associated fatty liver disease (MAFLD), is common in obese patients. Intragastric balloon (IGB), an obesity management tool with low complication risk, might be used in MAFLD treatment but there is still unexplained heterogeneity in results across studies. METHODS We conducted a systematic search of 152 citations published up to September 2020. Meta-analyses, stratified analyses, and meta-regression were performed to evaluate the efficacy of IGB on homeostasis model assessment of insulin resistance (HOMA-IR), alanine aminotransferase (ALT), aspartate aminotransferase (AST), and gamma-glutamyl transpeptidase (GGT), and to identify patients most appropriate for IGB therapy. RESULTS Thirteen observational studies and one randomized controlled trial met the inclusion criteria (624 participants in total). In the overall estimate, IGB therapy significantly improved the serum markers change from baseline to follow-up [HOMA-IR: 1.56, 95% confidence interval (CI)=1.16-1.95; ALT: 11.53 U/L, 95% CI=7.10-15.96; AST: 6.79 U/L, 95% CI=1.69-11.90; GGT: 10.54 U/L, 95% CI=6.32-14.75]. In the stratified analysis, there were trends among participants with advanced age having less change in HOMA-IR (1.07 vs. 1.82). The improvement of insulin resistance and liver biochemistries with swallowable IGB therapy was no worse than that with endoscopic IGB. Multivariate meta-regression analyses showed that greater HOMA-IR loss was predicted by younger age (p=0.0107). Furthermore, effectiveness on ALT and GGT was predicted by basal ALT (p=0.0004) and GGT (p=0.0026), respectively. CONCLUSIONS IGB is effective among the serum markers of MAFLD. Younger patients had a greater decrease of HOMA-IR after IGB therapy.

Abstract
The prevalence of obesity, type 2 diabetes mellitus, and metabolic syndromes is increasing globally. Minimally invasive metabobariatric (MB) endoscopic therapies are adjunct treatments that can potentially bridge the gap between surgical interventions and medical therapy. A growing number of MB techniques are becoming available, allowing for more personalized and patient-targeted treatment options for specific disease states. MB techniques are less invasive than surgery and can precisely target different parts of the gastrointestinal tract that may be responsible for the pathophysiology of obesity and metabolic syndromes such as type 2 diabetes mellitus. These alternatives should be selected on an individualized patient basis to balance the expected clinical outcomes and desired anatomical targets with the level of invasiveness and degree of acceptable risk. Each MB intervention presents great flexibility allowing for a tailored intervention and different levels of patient engagement. Patient awareness and motivation are essential to avoid therapy withdrawal and failure. Differences between MB procedures in terms of weight loss and metabolic benefit will be discussed in this review, along with the insights on clinical decision-making processes to evaluate the potential of further evolution and growth of bariatric and metabolic endoscopy.

Abstract
BACKGROUND AND OBJECTIVES Obesity and its related comorbidities are associated with serious health risks. This trial evaluated the safety and effectiveness of the ORBERA® Intragastric Balloon System (IGB) as an adjunct to lifestyle intervention in a post-marketing clinical setting. METHODS AND MATERIALS In this multicenter study, 258 adults with a body mass index of 30-40 kg/m2 were treated with the IGB as an adjunct to weight reduction and followed for up to 12 months. The primary objective was to demonstrate in a post-marketing clinical setting that the incidence of device and procedure-related serious adverse events (SAEs) after 26 weeks of IGB treatment is no greater than 15%. RESULTS The incidence of device and procedure-related SAEs was 8.9% with a 1-sided upper limit confidence interval of 12.4%, compared with the 9.6% overall SAE rate seen in the US pivotal study; therefore, the primary safety endpoint was met. The key secondary effectiveness endpoint was also met with a mean maximum %TBWL of 12.5 being achieved at the time of IGB removal (26 weeks). CONCLUSIONS The post-marketing safety and effectiveness profile of the IGB are consistent with what was observed in the US pivotal study. No new risks were identified.

Abstract
The intragastric balloon is a temporary and minimally invasive therapy for weight loss, currently being the main choice for mild obesity. As a space-occupying device, it reduces stomach capacity, resulting in decreased hunger and food intake. There are different balloon models, filled with liquid or air. The most used is the non-adjustable liquid-filled balloon, due to its lower rate of complications. The mechanism of action is multifactorial, involving physiological and neurohormonal changes. The device functions as an artificial bezoar, filling the stomach and leading to early satiety. In the Brazilian Intragastric Balloon Consensus Statement, there was a mean excess weight loss of 18.4%, showing effective weight loss and good safety profile. It is a valid option for overweight and obese patients unresponsive to clinical therapy or who are either not candidates for surgery or who do not wish to undergo a definitive procedure. Besides weight loss, recent studies have shown a positive effect on metabolic parameters. New devices have been developed, such as procedureless and adjustable balloons, with promising results.

Abstract
Obesity is becoming increasingly prevalent worldwide, and its metabolic sequelae lead to a significant burden on healthcare resources. Options for the management of obesity include lifestyle modification, pharmacological treatment, surgery, and endoscopic bariatric therapies (EBTs). Among these, EBTs are more effective than diet and lifestyle modification and are less invasive than bariatric surgery. In recent years, there have been significant advances in technologies pertaining to EBTs. Of all the available EBTs, there is a significant amount of clinical experience and published data regarding intragastric balloons (IGBs) because of their comparatively long development period. Currently, the United States Food and Drug Administration (FDA) has approved three IGBs, including Orbera (Apollo Endosurgery, Austin, TX, USA), ReShape Duo (ReShape Medical, San Clemente, CA, USA), and Obalon (Obalon Therapeutics, Carlsbad, CA, USA). The aim of this review is to summarize the available literature on the efficacy of IGBs in weight loss and their impact on obesity-related metabolic diseases.
