RESUMEN
Obesity in the United States is increasing, with the most recent national data indicating a prevalence of 41.9%. Obesity is generally considered a body mass index (BMI) of 30 kg per m2 or greater; however, increased waist circumference (female: 35 inches or greater; male: 40 inches or greater) may be a more accurate indicator of obesity, particularly in older adults. For patients who are overweight or obese, the history should include whether patients are taking medications that can increase weight and identifying comorbid conditions contributing to or resulting from obesity. Clinicians should also ask about previous weight-management strategies and whether they were effective. Initial laboratory testing includes a complete blood count, metabolic profile, lipids, thyroid-stimulating hormone and A1C levels, and additional testing as needed. The Obesity Medicine Association recommends that weight management incorporate five pillars: behavioral counseling, nutrition, physical activity, pharmacotherapy, and, when appropriate, bariatric procedures. Pharmacotherapy with anti-obesity medications such as glucagon-like peptide-1 receptor agonists, sympathomimetics, and others should be considered for any patient with a BMI of 30 kg per m2 or greater and for any patients who are overweight (i.e., BMI of 27 kg per m2 or greater) with metabolic comorbidities. Referral for bariatric surgery should be considered for patients who meet the criteria. Successful management requires individualized support systems with periodic follow-ups through each phase of treatment.

AIMS: Obesity is a significant health issue. Te Whatu Ora Waitemata serves a population of 650,000 patients across the North Shore, Waitakere and Rodney areas. The Waitemata bariatric service at North Shore Hospital was introduced in October 2001. The aim of this study was to review the development and impact of the service over the last 20 years, and identify whether equivalent bariatric services could viably be introduced into other hospitals in Aotearoa New Zealand. METHODS: A retrospective audit was conducted of the 20-year results of the Waitemata bariatric surgical service to identify the impact of technology, teaching and research on service provision. RESULTS: Since its inception, the Waitemata bariatric service has launched minimally invasive surgery, multiple operative options and an enhanced recovery after surgery (ERAS) protocol. Approximately 100 cases are performed per year. Of these, 3.4% of patients require admission to the intensive care unit/high dependency unit (ICU/HDU), with an average length of stay (LOS) of 0.66 days. The 1-year mortality rate is 0.39%. Eleven surgical fellows have undergone post-fellowship training with the service, which is a recognised training unit for the post-fellowship AANZGOSA/ANZMOSS programme. CONCLUSIONS: Bariatric surgery can be performed safely and has good long-term outcomes. The Waitemata bariatric service is dedicated to providing excellent care within the resource constraints of a public healthcare system. The high number of procedures, low requirement for ICU/HDU and low mortality rate suggest that bariatric surgery could be safely performed within a public setting in secondary and regional hospitals across the country.

Importance: Bariatric surgery is associated with decreased risk of obesity-related cancer and cardiovascular disease but is typically reserved for patients younger than 60 years. Whether these associations hold for patients who undergo surgery at older ages is uncertain. Objective: To determine whether bariatric surgery is associated with a decreased risk of obesity-related cancer and cardiovascular disease in patients who underwent surgery at age 60 years or older. Design, Setting, and Participants: Population-based cohort study of patients from Denmark, Finland, and Sweden who underwent bariatric surgery at age 60 years or older without previous malignant neoplasm or cardiovascular disease between 1989 and 2019. Each patient who underwent surgery was exactly matched to 5 patients with nonoperative treatment for obesity of the same country, sex, and age at the date of surgery. Data were analyzed in December 2023. Exposure: Receiving treatment for obesity, including bariatric surgery and nonoperative treatments. Main Outcomes and Measures: The main outcome was obesity-related cancer, defined as a composite outcome of breast, endometrial, esophageal, colorectal, and kidney cancer, identified from the national cancer registries. The secondary outcome was cardiovascular disease, defined as a composite outcome of myocardial infarction, ischemic stroke, and cerebral hemorrhage, identified from the patient registries. Multivariable Cox regression provided hazard ratios (HR) with 95% CIs adjusted for diabetes, hypertension, peripheral vascular disease, chronic obstructive pulmonary disease, kidney disease, and frailty. Results: In total, 15â¯300 patients (median [IQR] age, 63 [61-65] years; 10â¯152 female patients [66.4%]) were included, of which 2550 (16.7%) had bariatric surgery at age 60 or older and 12â¯750 (83.3%) had nonoperative treatment. During a median (IQR) of 5.8 (2.8-8.5) person-years of follow-up, 658 (4.3%) developed obesity-related cancer and 1436 (9.4%) developed cardiovascular disease. The risk of obesity-related cancer (HR, 0.81; 95% CI, 0.64-1.03) and cardiovascular disease (HR, 0.86; 95% CI, 0.74-1.01) were similar among who underwent surgery and those who did not. Gastric bypass (1930 patients) was associated with a decreased risk of obesity-related cancer (71 patients [3.7%]; HR, 0.74; 95% CI, 0.56-0.97) and cardiovascular disease (159 patients [8.2%]; HR, 0.82; 95% CI, 0.69-0.99) compared with matched controls (9650 patients; obesity-related cancer: 442 patients [4.6%]; cardiovascular disease: 859 patients [8.9%]). Conclusions and Relevance: This cohort study found that bariatric surgery in older patients is not associated with lower rates of obesity-related cancer and cardiovascular events, but there was evidence that gastric bypass may be associated with lower risk of both outcomes.

BACKGROUND: This study compares the effect of positive end-expiratory pressure (PEEP) on postoperative pulmonary complications (PPCs) in patients with obesity undergoing laparoscopic bariatric surgery (LBS) under general anesthesia with mechanical ventilation. METHODS: A comprehensive search was conducted in PubMed, Embase, Web of Science, Cochrane Central Register of Controlled Trials, China National Knowledge Internet, Wanfang database, and Google Scholar for studies published up to July 29, 2023, without time or language restrictions. The search terms included "PEEP," "laparoscopic," and "bariatric surgery." Randomized controlled trials comparing different levels of PEEP or PEEP with zero-PEEP (ZEEP) in patients with obesity undergoing LBS were included. The primary outcome was a composite of PPCs, and the secondary outcomes were intraoperative oxygenation, respiratory compliance, and mean arterial pressure (MAP). A fixed-effect or random-effect model was selected for meta-analysis based on the heterogeneity of the included studies. RESULTS: Thirteen randomized controlled trials with a total of 708 participants were included for analysis. No statistically significant difference in PPCs was found between the PEEP and ZEEP groups (risk ratio = 0.27, 95% CI: 0.05-1.60; p = 0.15). However, high PEEP ≥ 10 cm H2O significantly decreased PPCs compared with low PEEP < 10 cm H2O (risk ratio = 0.20, 95% CI: 0.05-0.89; p = 0.03). The included studies showed no significant heterogeneity (I2 = 20% & 0%). Compared with ZEEP, PEEP significantly increased intraoperative oxygenation and respiratory compliance (WMD = 74.97 mm Hg, 95% CI: 41.74-108.21; p < 0.001 & WMD = 9.40 ml cm H2O- 1, 95% CI: 0.65-18.16; p = 0.04). High PEEP significantly improved intraoperative oxygenation and respiratory compliance during pneumoperitoneum compared with low PEEP (WMD = 66.81 mm Hg, 95% CI: 25.85-107.78; p = 0.001 & WMD = 8.03 ml cm H2O- 1, 95% CI: 4.70-11.36; p < 0.001). Importantly, PEEP did not impair hemodynamic status in LBS. CONCLUSIONS: In patients with obesity undergoing LBS, high PEEP ≥ 10 cm H2O could decrease PPCs compared with low PEEP < 10 cm H2O, while there was a similar incidence of PPCs between PEEP (8-10 cm H2O) and the ZEEP group. The application of PEEP in ventilation strategies increased intraoperative oxygenation and respiratory compliance without affecting intraoperative MAP. A PEEP of at least 10 cm H2O is recommended to reduce PPCs in patients with obesity undergoing LBS. REGISTRATION NUMBER: CRD42023391178 in PROSPERO.

Metabolic and bariatric surgery (MBS) effectively treats obesity and related comorbidities, though individual responses vary. This systematic review examines how genetic variants influence MBS outcomes in morbidly obese patients. A comprehensive search in PubMed, Embase, Medline, and the Cochrane Library identified 1572 studies, with 52 meeting the inclusion criteria. Two reviewers independently filtered and selected studies, including relevant cross-references. Research focused on polymorphisms in genes such as UCP2, UCP3, 5-HT2C, MC4R, FKBP5, FTO, CAT haplotypes, LYPAL-1, PTEN, FABP-2, CNR1, LEP656, LEP223, GLP-1R, APOA-1, APOE, ADIPOQ, IL-6, PGC1a, TM6SF2, MBOAT7, PNPLA3, TCF7L2, ESR1, GHSR, GHRL, CD40L, DIO2, ACSL5, CG, TAS2R38, CD36, OBPIIa, NPY, BDNF, CLOCK, and CAMKK2. Most studies explored associations with post-surgery weight loss, while some examined metabolic, cardiovascular, taste, and eating behavior effects as well. Understanding the role of genetic factors in weight loss and metabolic outcomes post-MBS can help tailor personalized treatment plans for improved efficacy and long-term success. Further research with larger sample sizes and extended follow-up is needed to clarify the effects of many genetic variants on MBS outcomes in morbidly obese patients.

BACKGROUND: Bariatric surgery is an effective treatment option for obesity and provides long-term weight loss and positive effects on metabolism, but the underlying mechanisms are poorly understood. Alterations in bile acid metabolism have been suggested as a potential contributing factor, but comprehensive studies in humans are lacking. METHODS: In this study, we analysed the postprandial responses of bile acids, C4 and FGF19 in plasma, and excretion of bile acids in faeces, before and after bariatric surgery in patients (n = 38; 74% females) with obesity with or without type 2 diabetes from the BARIA cohort. FINDINGS: We observed that total fasting plasma bile acid levels increased, and faecal excretion of bile acids decreased after surgery suggesting increased reabsorption of bile acids. Consistent with increased bile acid levels after surgery we observed increased postprandial levels of FGF19 and suppression of the bile acid synthesis marker C4, suggesting increased FXR activation in the gut. We also noted that a subset of bile acids had altered postprandial responses before and after surgery. Finally, fasting plasma levels of 6α-hydroxylated bile acids, which are TGR5 agonists and associated with improved glucose metabolism, were increased after surgery and one of them, HDCA, covaried with diabetes remission in an independent cohort. INTERPRETATION: Our findings provide new insights regarding bile acid kinetics and suggest that bariatric surgery in humans alters bile acid profiles leading to activation of FXR and TGR5, which may contribute to weight loss, improvements in glucose metabolism, and diabetes remission.

This study investigates gender-specific differences in obesity and the treatment by metabolic bariatric surgery (MBS). The database includes 2393 patients (1725 women, 668 men) from for a high-volume center for bariatric surgery. Demographic, perioperative and follow-up data were retrospectively analyzed. Men had a significantly higher body mass index (BMI) and more frequent obesity-associated diseases. Despite the higher prevalence of obesity in men, women accounted for 80% of the surgical patients. On average men had longer operation times but with the same complication rates. Postoperatively, both sexes experienced a significant reduction in excess body weight, which was slightly more pronounced in women. The study particularly emphasizes the need to better motivate men to undergo obesity treatment in order to reduce the health consequences of morbid obesity in this population group.

Nonalcoholic fatty liver disease (NAFLD), the most common chronic hepatic disease, has become a leading health problem worldwide. The present review summarized the methods and mechanisms to treat NAFLD, including the Mediterranean diet, physical activity and exercise, bariatric surgery and specific therapeutic agents, including statins, peroxisome proliferatoractivated receptor agonists, cenicriviroc and farnesoid X receptor agonists. Biologically active substances, such as peptides, alkaloids, polyphenolic compounds, silymarin, antibiotics, fatty acids, vitamins, probiotics, synbiotics and lamiaceae have also demonstrated actions that combat NAFLD. Considering their different mechanisms of action, combining some of them may prove an efficacious treatment for NAFLD. In this light, the present review describes recent progress and future prospects in treating NAFLD.

INTRODUCTION: The quality of hospital care, especially surgery, is traditionally assessed using indicators derived from healthcare databases or safety indicators. Given the growing importance of placing the patient at the heart of care evaluation, the use of questionnaires such as the Patient-Reported Experience Measures and Patient-Reported Outcome Measures has become widespread in recent years. However, these tools-addressing factors such as satisfaction, pain management or wait times-only imperfectly reflect the patient's experience, and all such attempts at patient-centred care quality assessment rely on questions or indicators defined in advance by healthcare providers and health authorities. A biopsychosocial model may allow to better understand the patient experience and to improve care pathways. This study seeks to construct a narrative of the bariatric surgical care journey with instruments from narrative inquiry, propose a metanarrative that can serve as a basis for more sophisticated and reliable patient-focused care quality models and define indicators linked to patients' feelings and stories. METHODS AND ANALYSIS: To achieve these aims, 16 bariatric surgical patients at the hospital of Créteil, France (Centre Hospitalier Intercommunal de Créteil), will be included and interviewed once before and twice after surgery, at months 3 and 6. Narratives collected will be used to construct a metanarrative intended to encompass all possible narratives. This metanarrative may ultimately inform new patient care quality indicators, furthering care focused on patients and tailored to their needs and predispositions. ETHICS AND DISSEMINATION: The study is funded by the Group of Clinical Research and Innovation in Île-de-France and was approved by CPP SUD-EST VI Clermont-Ferrand (France) Research Ethics Committee. The results will be submitted for publication in peer-reviewed journals. The patient associations will be approached for the dissemination of the study results. TRIAL REGISTRATION NUMBER: NCT05092659.

Introduction: Obesity is a pathological state that involves the dysregulation of different metabolic pathways and adipose tissue cells, constituting a risk factor for the development of other diseases. Bariatric surgery is the most effective treatment. The study of the behavior of pollutants in situations of extreme weight loss can provide biomonitoring information and tools to manage diseases of environmental etiology. Aim: To determine the prevalence of serum persistent and non-persistent pollutants in obese patients subjected to bariatric surgery and analyze the impact of sociodemographic variables on these changes. Methods: GC-MS/MS and UHPLC-MS/MS were utilized to determine the detection rates and concentrations of 353 compounds, including persistent organic pollutants (POPs), pesticides, pharmaceuticals, and rodenticide, in serum samples of 59 obese patients before and after undergoing bariatric surgery. Results: Detection rates of p,p'-DDE, HCB, ß-HCH, naphthalene, phenanthrene and PCB congeners 138, 153 and 180 significantly increased due to surgery-induced weight loss. Serum levels of p,p'-DDE, PCB-138, PCB-153 and PCB-180 also increased after surgery. Correlations between naphthalene levels, weight loss, variation of total lipids and time after surgery were found. Additionally, correlations were observed between concentrations of PCB-138 and weight loss, and between phenanthrene levels and reduction of total lipids. No statistically significant differences were observed for other groups of contaminants, pharmaceuticals and other chemicals included in the quantification methods. Conclusions: Increment of POPs was observed after bariatric surgery. Serum concentrations of POPs after surgery were influenced by adiposity-related variables. Although biomonitoring studies show a decreasing tendency of exposure, rapid weight loss leads to an increase of circulating POPs. Further research on the interplay between adipose tissue, POPs and peripheral organs is required.

INTRODUCTION: The objectives of this study were to examine temporal trends in the incidence of bariatric surgery (Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG)) in patients with and without type 2 diabetes mellitus (T2DM). Outcomes of hospitalization and the impact of T2DM on these outcomes were also analyzed. RESEARCH DESIGN AND METHODS: We performed an observational study with the Spanish national hospital discharge database. Obese patients with and without T2DM who underwent RYGB and SG between 2016 and 2022 were identified. Propensity score matching (PSM) and logistic regression were used to compare patients with and without T2DM and to evaluate the effect of T2DM and other variables on outcomes of surgery. A variable "severity" was created to cover patients who died in hospital or were admitted to the intensive care unit (ICU). RESULTS: A total of 32,176 bariatric surgery interventions were performed (28.86% with T2DM). 31.57% of RYGBs and 25.53% of SG patients had T2DM. The incidence of RYGB and SG increased significantly between 2016 and 2022 (p<0.001), with a higher incidence in those with T2DM than in those without (incidence rate ratio 4.07 (95% CI 3.95 to 4.20) for RYGB and 3.02 (95% CI 2.92 to 3.14) for SG). In patients who underwent SG, admission to the ICU and severity were significantly more frequent in patients with T2DM than in those without (both p<0.001). In the multivariate analysis, having T2DM was associated with more frequent severity in those who received SG (OR 1.23; 95% CI 1.07 to 1.42). CONCLUSIONS: Between 2016 and 2022, bariatric surgery procedures performed in Spain increased in patients with and without T2DM. More interventions were performed on patients with T2DM than on patients without T2DM. RYGB was the most common procedure in patients with T2DM. The presence of T2DM was associated with more severity after SG.

BACKGROUND: Food intakes 1-2 years following bariatric surgery depend more on patients than the surgery's gastrointestinal tract changes. This study aimed to determine the major dietary patterns of patients after the first two years of sleeve gastrectomy and to investigate their associations with total weight loss (TWL) and the proportion of TWL as fat mass (FM) and fat-free mass (FFM) loss. METHODS: This cross-sectional study included 146 patients undergoing sleeve gastrectomy 2-4 years after surgery. Dietary patterns were determined using principal component analysis based on the 19 food groups. The percentage of FM loss relative to TWL (%FML) and FFM loss relative to TWL (%FFML) were calculated. A suboptimal clinical response was defined as a TWL of less than 25%. High FM loss and excessive FFM loss were defined based on the highest tertiles. Linear and logistic regression models were used to derive unstandardized (B) coefficients and odds ratios (OR), with dietary pattern scores serving as both a continuous and a binary variable (higher vs. lower adherence groups based on median). RESULTS: Two predominant dietary patterns were retained. Each 1-unit increase in the first dietary pattern score characterized by high intakes of fast foods, soft drinks, processed meats, sugar confectionary, salty snacks, grains, and organ meats was associated with higher %FFML (B = 1.99; 95% confidence interval (CI) 0.34, 3.66), lower %FML (B = - 1.84; 95% CI - 3.49, - 0.20), and higher odds of excessive FFM loss (OR = 1.84; 95% CI 1.09, 3.11). Participants with higher adherence to the first dietary pattern had lower %TWL, and greater odds of suboptimal clinical response and excessive FFM loss than those with lower adherence. Each 1-unit increase in score for the second dietary pattern characterized by a high intake of fruits, dairy, vegetables, legumes, eggs, nuts, red meats, poultry, and fish was associated with lower odds of suboptimal clinical response (OR = 0.51; 95% CI 0.31, 0.86). CONCLUSION: Patients should be encouraged to modify their diet by reducing the consumption of ultra-processed foods and increasing their intake of high-quality protein sources, fruits, and vegetables to achieve the best postoperative outcome.

Avoidable readmissions after bariatric surgery are a major burden on the healthcare systems. Rates of readmission after bariatric surgery have ranged from 1% up to 20%, but the factors that predict readmission have not been well studied. The objective of this study was to determine readmission rates following bariatric surgery and identify factors that contribute to early (within 90 days of surgery) and late readmission. A retrospective cohort study of 736 patients undergoing either Laparoscopic Sleeve Gastrectomy or Laparoscopic Roux-en-Y Gastric Bypass in Jordan University Hospital from 2016 to 2019. Demographic characteristics, co-morbidities, and readmissions were extracted from their medical records and analyzed. Multivariable logistic regression analysis was performed to determine which factors predict readmission. A total of 736 patients had bariatric surgery (Laparoscopic Sleeve Gastrectomy 89% vs Laparoscopic Roux-en-Y Gastric Bypass 11%) during the study period. Thirty-day readmission rate was 6.62% and an overall readmission rate of 23.23%. Common reasons for early readmission (within 90 days of surgery) were nausea, vomiting, and dehydration. Late readmissions were mainly caused by gallbladder stones. Three risk factors were identified that independently predicted readmission: the type of procedure being performed (P-valueâ =â .003, odds ratio [OR] 2.14, 95% confidence interval [CI] 1.32-3.49), depression (P-valueâ =â .028, OR 6.49, 95% CI 1.18-52.9) and preoperative body mass index (P-valueâ =â .011, OR 1.03, 95% CI 1.01-1.05). Several factors were identified that cause patients to represent and subsequently admitted into hospitals. Early readmission was usually due to nausea, vomiting, and dehydration, whereas late admissions were mostly due to biliary complications. Preoperative body mass index and depression were independent risk factors for readmission.

The application of a robotic platform in the bariatric surgical field is intended to enhance the already established advantages of minimally invasive surgery in terms of both technical and clinical outcomes. These advantages are especially relevant for technically challenging multiquadrant operations such as Roux-en-Y Gastric Bypass (RYGB). Consequently, robotic-assisted surgery has emerged as a possible application for bariatric surgeries. The study attempts to assess feasibility and safety of the Hugo™-Robotic-Assisted Surgery System (Hugo™-RAS) platform compared to the DaVinci® Surgical System (DaVinci®-SS) with a focus on complication rates and operative times. We retrospectively reviewed bariatric procedures performed from January 2013 until December 2023. We included all robotic RYGBs performed using Hugo™-RAS and DaVinci®-SS platforms. The study utilized Propensity Score Matching (PSM) analysis to address bias in selection, matching patients based on age, gender, body mass index, comorbidities and past abdominal operations. One hundred thirty-five patients were identified: 90 DaVinci®-SS and 45 Hugo™-RAS procedures. After PSM, each group consisted of 45 patients. There was no discernible disparity observed in relation to early (≤ 30 days) postoperative complications rate (p = 1), mean operative time (for docking time, console time and total operative time: p = 0.176, p = 0.678, p = 0.229, respectively) and postoperative hospital stay (p = 0.052) between DaVinci®-RSS and Hugo™-RAS procedures. Our results suggest that application of both Hugo™-RAS and DaVinci®-SS robotic platforms to RYGB is related to comparable safety profiles. Although DaVinci®-SS remains the most widely adopted platform in clinical practice, this study underscores the potential role of the Hugo™-RAS to provide effective solutions in robotic bariatric procedures.

Due to an increase in the worldwide prevalence of obesity and the efficiency of bariatric surgery, this procedure is more often performed. Besides its benefits, it has also disadvantages and may be the cause of nutritional deficiencies. Thiamin deficiency is particularly important to diagnose and to treat early as it can lead to major sequelae and even to death. Wernicke's encephalopathy is the most frequent presentation associating confusion, ataxia, ophtalmoplegia and nystagmus. The full triad is not usually observed, which may lead to sub-diagnosis of this affection. The diagnosis is clinical, biological and radiologic thanks to the brain MRI. Intravenous thiamin supplementation therapy must be administered as fast as possible in order to avoid long-term damages. In the ophthalmological field, the potential sequelae are ophthalmoplegia, nystagmus and optic neuropathy. Therapeutics for nystagmus are pharmacological, surgical and/or optical. We illustrate this condition with a case report of an 18-year-old man developing Wernicke's encephalopathy as early as six weeks after a sleeve gastrectomy.
Suite à une augmentation de la prévalence de l'obésité dans le monde et à l'efficacité de la chirurgie bariatrique, cette technique est pratiquée de plus en plus fréquemment. Malgré ses avantages, elle n'est pas sans risque et peut être responsable de déficits nutritionnels multiples. Le déficit en vitamine B1 ou thiamine est particulièrement important à connaître et, à rapidement diagnostiquer en raison des nombreuses séquelles invalidantes, voire le décès du patient, dont il peut être responsable. Le tableau classique est l'encéphalopathie de Gayet-Wernicke associant confusion, ataxie et troubles oculomoteurs. Néanmoins, il n'est pas toujours complet, ce qui participe au sous-diagnostic de cette pathologie. Le diagnostic est clinique, biologique et/ou radiologique grâce à l'IRM cérébrale. La supplémentation vitaminique intraveineuse doit être instaurée le plus rapidement possible afin d'éviter des séquelles à long terme. D'un point de vue ophtalmologique, les séquelles potentielles sont les ophtalmoplégies, les nystagmus et les neuropathies optiques. Les thérapies envisageables du nystagmus, outre la supplémentation en thiamine en aigu, sont pharmacologiques, chirurgicales et/ou optiques. Nous illustrons cette pathologie par un cas clinique d'encéphalopathie de Gayet-Wernicke dès la 6ème semaine post-opératoire d'une chirurgie bariatrique de type «sleeve¼ chez un patient de 18 ans.

Obesity impacts mental health greatly. Psychological factors may influence the effectiveness of its treatment. This study aimed to compare symptoms of generalised anxiety disorder and depression among adult women across different weight categories. The study sample comprised 1105 adult women. The computer-assisted web interview (CAWI) utilising the seven-item Generalised Anxiety Disorders Scale (GAD-7) and the nine-item Patient Health Questionnaire (PHQ-9) was used. Both GAD-7 and PHQ-9 scores correlated positively with BMI (r = 0.121, p < 0.001 and r = 0.173, p < 0.001, respectively) and negatively with age (r = -0.106, p < 0.001 and r = -0.103, p < 0.001, respectively). Patients undergoing treatment with semaglutide scored lower for both anxiety symptoms (8.71 ± 6.16, p = 0.013) and depression symptoms (9.76 ± 6.37, p = 0.013). Women who underwent bariatric surgery screened less frequently for anxiety (8.03 ± 6.27, p = 0.002) but not for depression. An interdisciplinary approach involving mental health professionals within the therapeutic team can comprehensively address factors contributing to obesity development and treatment outcomes. Further investigation of semaglutide's use is needed due to the promising evidence suggesting a positive effect on decreasing the severity of depression and anxiety symptoms to assess the direct or indirect character of this influence.

BACKGROUND: Outcomes of bariatric surgery (BS) in patients with schizophrenia are poorly understood. We aimed to analyze the effects of BS in patients with schizophrenia (SZ) or schizoaffective disorder (SZA). METHODS: This was a multicenter, retrospective case-control study in patients with SZ or SZA who had undergone BS in seven public referral hospitals in Spain. Controls without psychiatric comorbidity were selected in a 1:4 ratio. Detailed clinical and biochemical data were collected preoperatively and at 12, 24, 36, 48, and 60 months after BS. RESULTS: Twenty patients with SZ (n = 15; 75%) or SZA (n = 5; 25%) and 80 matched controls were studied. There were no differences between patients and controls concerning the evolution of the percentage of total weight loss. The remission rate of the main comorbidities was similar between groups except for hypertension, which was lower in patients with a psychotic disorder from year 3. There were no mortalities within 30 days of surgery in either group. The psychiatric medication burden did not change during follow-up. CONCLUSIONS: BS is safe and effective in carefully selected patients with SZ. The course of the psychiatric disease does not seem to be worsened by the procedure.

Metabolic bariatric surgery remains the most effective and durable treatment for severe obesity. Women of reproductive age represent the largest demographic group undergoing these procedures. Metabolic bariatric surgery can have both beneficial and adverse effects on pregnancy outcomes. One of the most common adverse effects is fetal growth restriction. To mitigate these adverse effects, it is crucial to explore lifestyle modifications aimed at promoting a healthy pregnancy. Modifiable factors during pregnancy after metabolic bariatric surgery include the amount of gestational weight gain. The aim of this comprehensive review is to provide an overview of what is known about gestational weight gain in pregnancy after bariatric metabolic surgery. This review is focused on the two most performed procedures: sleeve gastrectomy and Roux-en-Y gastric bypass.

BACKGROUND: Cholelithiasis is one of the more common complications following bariatric surgery. This may be related to the rapid weight loss during this period, although the exact mechanism of gallstone formation after bariatric surgery has not been fully elucidated. METHODS: The present literature review focuses on risk factors, prevention options and the impact of the gut microbiota on the development of gallbladder stones after bariatric surgery. RESULTS: A potential risk factor for the development of cholelithiasis after bariatric surgery may be changes in the composition of the intestinal microbiota and bile acids. One of the bile acids-ursodeoxycholic acid-is considered to reduce the concentration of mucin proteins and thus contribute to reducing the formation of cholesterol crystals in patients with cholelithiasis. Additionally, it reduces the risk of both asymptomatic and symptomatic gallstones after bariatric surgery. Patients who developed gallstones after bariatric surgery had a higher abundance of Ruminococcus gnavus and those who did not develop cholelithiasis had a higher abundance of Lactobacillaceae and Enterobacteriaceae. CONCLUSION: The exact mechanism of gallstone formation after bariatric surgery has not yet been clarified. Research suggests that the intestinal microbiota and bile acids may have an important role in this.
