Surgical complications of bariatric surgery among patients with rheumatic diseases.

Obesity is one the most prevalent diseases all around the world. Some studies have shown a relationship between obesity and the worsening of rheumatic disorders. Higher rates of surgical complications might also be seen among these patients. This retrospective-descriptive study was performed on 25 patients with rheumatic disease referred to Loghman Hakim Hospital (Tehran- Iran) and candidates for bariatric surgery (laparoscopic Roux-en-Y gastric and laparoscopic sleeve gastrectomy) from 2018 to 2020. Duration of hospitalization after surgery and history of post-operation surgical and rheumatic complications were assessed. Patients were followed through 6 months after surgery. The age (Mean±SD) of recruited patients was (38.4 ±10.0) years. The mean body mass index was 45.54 kg/m2 with the minimum and maximum values of 37.5 kg/m2 and 56.5 kg/m2. Among them, the prevalence of rheumatic disorders was rheumatoid arthritis 32%, psoriasis 28%, gout 16%, lupus erythematosus 8%, and other rheumatologic disorders 16%, respectively. One patient had a surgical complication that was a port site infection. One patient had a relapse of gout and other patients had remission and also, their therapeutic drugs were discontinued or reduced. Patients with rheumatic disorders revealed no higher surgical complication rate after bariatric surgery, and bariatric surgery helped disease remission among these patients.

Differences in the cluster of depressive symptomatology among bariatric surgery candidates, long-term bariatric surgery patients, and subjects with a major depressive disorder without obesity.

depression is more frequent among people with obesity (PwO) compared to the general population. Depression seems to improve after bariatric surgery (BS) at short term, but data are inconclusive at long term. Besides, it is not known whether depressive symptoms among PwO are similar to those people with a major depression without obesity. we aimed to study whether there are differences regarding depressive symptomatology among subjects seeking BS or patients after BS in the long-term compared with subjects with MDD. the Beck Depression Inventory (BDI) was administered to three groups: 52 patients seeking BS (OB), 135 patients with a BS with a minimum follow-up of 18 months (BS) and 45 subjects with a MDD (MDD). the MDD obtained the higher score with the BDI whether compared to the OB (18.9 ± 12.7 vs 14.2 ± 6.9; p = 0.01) or the BS (18.9 ± 12.7 vs 8.1 ± 8; p < 0.0001). Also, BS presented a lower BDI than the OB (8.1 ± 8 vs 14.2 ± 6.9; p < 0.0001). The MDD scored higher in the psychological domain than patients in the OB (9.9 ± 7.5 vs 5.7 ± 5.1; p < 0.0001) as well as in the BS (9.9 ± 7.5 vs 3.1 ± 3; p < 0.0001). There was a negative correlation between a greater score in the somatic domain and %EPP (p = 0.04). at long term, depressive symptomatology among subjects with a BS remained lower compared to PwO seeking BS.PwO presented a different cluster of depression compared to individuals with a MDD. BS reduces the somatic depressive cluster at long term, although its presence is associated to a lesser weight loss.

Exploring the Utility of the Rorschach Test in Predicting Weight Loss After Bariatric Surgery

Abstract: Bariatric surgery (BS) is an effective approach to treat severe obesity, which should include multidisciplinary care. Prior to surgery, candidates for BS usually undergo a psychological assessment based mostly on self-report of clinical symptoms. However, the results of this assessment are not always sufficient to predict outcomes. Therefore, this study examined the potential of a multimethod approach to assessing patients seeking BS using both self-report and performance-based measures of cognitive and affective functioning. A sample of 50 women who had applied for surgery at a public facility in Brazil were assessed with the Difficulties in Emotion Regulation Scale (DERS), the Rorschach Performance Assessment System (R-PAS), and the Trail Making Test (TMT). Patients who dropped out before treatment ( n = 27) had higher initial body mass index and poorer performance on cognitive flexibility at baseline. In the remaining 23 patients who underwent surgery, indicators of emotional and cognitive functioning from all measures were associated with weight loss (WL) at 6 and 12 months after surgery. However, only R-PAS variables regarding psychological resources were associated with WL 18 months after surgery. We discuss the usefulness of the Rorschach as a source of information for patients seeking BS and the implications for current assessment practices in the field.

Factors associated with grazing behavior in candidates for bariatric surgery at a hospital in the Amazon.

To assess grazing behavior and associated factors in candidates for bariatric surgery monitored at a public hospital that is a reference in the care of people with severe obesity. Cross-sectional analytical study, with candidates for bariatric surgery of both genders, treated in a public hospital in the Amazon. To assess grazing behavior, the Repetitive Eating Questionnaire was used, and to investigate patterns of eating behavior, the Three Factor Eating Questionnaire was used, which assesses: Emotional Eating, Cognitive Restriction and Uncontrolled Eating. Sociodemographic information was obtained through self-report and the description of medication use through the medical record. Body mass index (BMI) was also calculated by measuring weight and height. The SPSS program, v. 21.0 was used. The study was approved by the Research Ethics Committee. A total of 205 participants were evaluated, with a mean age of 37.5 ± 8.6 years, the majority (93.7%) being women and the majority (59.5%) was not also using medication to lose weight. About 66.3% of the participants had compulsive grazing. The factor with the highest score was cognitive restriction (p < 0.001). Individuals who used weight loss drugs had higher scores in the cognitive restriction factor (p = 0.015) and lower scores for uncontrolled eating (p = 0.008), compulsive grazing (p = 0.021) and non-compulsive grazing (p = 0.034). Linear regression showed that emotional eating and uncontrolled eating were predictors of both compulsive grazing and non-compulsive grazing behavior. It was observed that grazing behavior, cognitive restriction, emotional eating and uncontrolled eating are present and correlated in the studied patients. In addition, the use of weight loss drugs seems to help reduce dysfunctional eating behaviors in patients with severe obesity.

Pre- and Post-surgical Prevalence of Thiamine Deficiency in Patients Undergoing Bariatric Surgery: a Systematic Review and Meta-analysis.

Thiamine deficiency is a life-threatening nutritional abnormality observed in the patients with obesity and following bariatric surgery. The aim of the present study is to determine the prevalence of thiamine deficiency prior to and after bariatric procedures. PubMed, Web of Science, Google scholar, CENTRAL, ProQuest, and Scopus were searched to retrieve relevant studies containing data on thiamine deficiency in patients with obesity who underwent bariatric surgery. A proportional meta-analysis approach was used to pool the prevalence of thiamine deficiency prior and after surgery. Our comprehensive literature search retrieved 41 studies with relevant data. The pooled prevalence of thiamine deficiency was 7% (95% CI: 4-12%) at baseline. We observed that 19% (95% CI: 0-68%), 9% (95% CI: 3-17%), and 6% (95% CI: 3-9%) of patients had developed thiamine deficiency at 3 months, 6 months, and 1 year after surgery, respectively. We also report that the prevalence of thiamine deficiency in pregnant women who had history of bariatric surgery. The rate was highest in the first trimester (12%) compared to that in the second (8%) and third (10%) trimesters. The baseline prevalence is 7% for thiamine deficiency in bariatric surgery candidates. The prevalence rate of thiamin deficiency increased to 19% and 9% 3 and 6 months after surgery; however, the rate decreased to 6% 1 year after surgery. Due to the higher prevalence of thiamine deficiency in the early post-operative phase, close monitoring during this period is recommended. A similar strategy should be implemented for pregnant women with history of bariatric surgery in their first trimester.

IBC-Oxford University2023_BJSOral_25Early outcomes of Long Biliopancreatic Limb Roux-En-Y Gastric Bypass Versus One-Anastomosis Gastric Bypass

Abstract Background Roux-en-Y gastric bypass (RYGB) is the gold standard in bariatric surgery. The one-anastomosis gastric bypass (OAGB) procedure, first introduced by Dr. Rutledge, has demonstrated a 25% greater weight loss efficiency than the traditional Roux-en-Y gastric bypass (RYGB) procedure due to the substantially longer biliopancreatic limb (BPL). Aim of the study The current work aimed to compare the outcomes of OAGB and long BPL RYGB regarding weight loss and comorbidity resolution. Patients and methods This randomized controlled trial was done at our institution between September 2019 and January 2021. Patients who were candidates for bariatric surgery were randomly and equally allocated to two groups. Group A underwent OAGB, while group B underwent long BPL RYGB. Patients were followed up for 6 months postoperatively. Results This study included 62 patients equally allocated to OAGB or long BPL RYGB, with no dropouts during follow-up. At 6 months, there was no statistically significant difference between the two groups regarding postoperative BMI (P = 0.313) and the EBWL (P = 0.238). There was comparable remission of diabetes mellitus (P = 0.708), hypertension (P = 0.999), OSA (P = 0.999), joint pain (P = 0.999), and low back pain (P = 0.999). Seven patients in the OAGB group experienced reflux symptoms (P = 0.011), which were managed by proton pump inhibitors. Conclusion Extending the BPL in RYGB provides weight loss and comorbidity remission comparable to that of OAGB. Some OAGB-related reflux cases remain a concern. However, they were sufficiently controlled with PPIs. Due to OAGB superior technical simplicity, long BPL RYGB should be preserved for cases who at higher risk for bile reflux.

Assessment of electronic patient education materials for adolescent bariatric surgery candidates: An environment scan.

Adolescents who opt for metabolic and bariatric surgery (MBS) will use the internet to learn about the procedure. The objective of this study is to assess the suitability of electronic patient education materials (ePEM) of North American centers that perform adolescent bariatric surgery. Canadian and American bariatric centers that perform adolescent MBS were identified from the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program and Google web-based searches. Suitability of ePEM for the adolescent readership was evaluated using the Suitability Assessment of Materials (SAM). Sixty-five centers were evaluated from June to July 2020 with 41% citing adolescent specific material. Six percent of the ePEM were evaluated as 'not suitable', 69% were evaluated as 'adequate', and 25% were evaluated as 'superior'. Adequate ePEM scoring was obtained, but centers had little resources tailored to adolescent patients. Further research is needed to evaluate all the resources provided to adolescents (i.e., resources provided by the health team) to ensure the tools are appropriate for the adolescent readership. This environmental scan provided insights to ePEM available for adolescents considering MBS.

Prevalence of eating disorder symptomatology among outpatients referred to health promotion from somatic hospital departments

Background and AimsAll eating disorders (EDs) lead to a significant decrease of health status, psychosocial functioning and quality of life (QoL). Individuals with untreated binge eating disorder (BED) tend to gain weight over time, which may contribute to serious health issues. In somatic hospital departments, some outpatients have reduced compliance with lifestyle changes. This may, to some extent, be due to patients with an undiagnosed ED receiving the incorrect treatment. In this cross-sectional study, we aimed to investigate the prevalence of EDs among patients referred to lifestyle courses.ResultsA total of 136 patients referred from somatic hospital departments to lifestyle changes in a specialized hospital unit were included in the study. The response rate was 69.4%. Self-reported ED or sub-clinical symptoms of ED according to the Eating Disorder Examination Questionnaire (EDE-Q) were found in 17.65%. Of these, 11.03% fulfilled the self-reported criteria for an ED (BED, 7.35%; bulimia nervosa, 3.68%). Patients with an ED or subclinical ED symptoms had elevated grazing behaviour compared to those without ED symptomatology. A statistically significant difference in QoL was also found.Discussion and ConclusionsThe prevalence of self-reported ED or subclinical ED symptoms in patients referred to a lifestyle course is substantial. This ED group had reduced QoL and larger grazing behaviour compared to patients without ED symptomatology. Thus, the prevalence of undiagnosed EDs among patients within somatic hospital departments may be substantial, underlining the importance of screening and further research within this topic.Level of EvidenceLevel III, well-designed cohort study.SignificanceWhat is already known on this subject? In a review including populations from Scandinavia, the USA and South America, the estimated BED prevalence in individuals with higher body weight seeking help to lose weight is 13–27% [22]. Dawes et al. (2016) conducted a meta-analysis investigating the prevalence of mental health conditions among bariatric surgery candidates and recipients. They included 25 studies with a total of 13,769 patients and found that the prevalence of BED was 17% (13–21%) [10]. What this study adds? We have identified a group of patients who may be receiving inappropriate treatment with weight loss intervention instead of specialized ED intervention. It appears that this issue is valid in various somatic hospital departments. Thus, this is a field that requires further attention and investigation.

Eating disorders among bariatric surgery patients: The chicken or the egg?

Postoperative eating behaviors and unhealthy weight control measures are leading causes of bariatric surgery complications. Candidates for bariatric surgery and individuals with eating disorders may share common risk factors, such as a history of dieting, and/or being bullied or teased for their weight. Binge-eating disorder, night eating syndrome, and bulimia nervosa are the most common eating disorders among candidates for bariatric surgery before the operation. Malnutrition, stress, and intense fear of weight gain can lead to the development of an eating disorder after surgery as well. Plugging, grazing, loss of control eating, dumping, and food avoidance are specific disordered behaviors that may present after bariatric surgery. To improve physical and psychological outcomes for individuals under their care, clinicians can screen for these disordered behaviors and distinguish them from a healthy diet and the expected postsurgical course.

92 Teleneuropsychological Evaluation of Bariatric Surgery Candidates: Cognitive Profiles and Recommendations for Future Practice

Objective:Vascular complications, including elevated body mass index (BMI), are known risk factors for cognitive impairment. Obtaining a cognitive baseline is commonplace in pre-surgical protocols, including for Parkinson’s disease and epilepsy. Currently, routine evaluations for bariatric surgery candidates do not include neuropsychological assessment. This setting provides a unique opportunity to identify cognitive profiles of younger individuals at risk for cognitive impairment. Here, we argue for the standard implementation of a brief, online cognitive battery via telemedicine, to enhance existing protocols of bariatric pre-surgical evaluations.Participants and Methods:Nineteen bariatric surgery candidates were referred to a private neuropsychological assessment practice for pre-surgical cognitive/psychological evaluation. Assessments were conducted by a neuropsychologist and a psychology graduate student, via remote video conferencing, between April 2020 and June 2022. Candidates completed a clinical interview, intake form, and the Behavior Rating Inventory of Executive Function for Adults (BRIEF-A), and were administered a battery of cognitive measures: Wechsler Test of Adult Reading (WTAR), Hopkins Verbal Learning Test-Revised (HVLT-R); and select subtests from the TestMyBrain Digital Neuropsychology Toolkit: Trail Making Tests A and B (TMT-A/B), Matrix Reasoning (MR), Digit Span Forward and Backward (DSF, DSB), Gradual Onset Continuous Performance Test (CPT), and Simple and Choice Reaction Time (SRT, CRT). Descriptive statistics were conducted to analyze sample demographics. Raw scores on cognitive measures were converted to z-scores and averaged across the sample.Results:The average age at evaluation was 38.2 (9.6) years and average pre-surgical BMI was 46.6k/m2 (9.3), indicating morbid obesity (BMI&gt;40k/ m2). Ten (52.6%) candidates identified as female, 10 (52.6%) identified as White, 8 (42.1%) had 12 years of education or less, 4 (21.1%) were unemployed, and 9 (47.4%) had comorbid psychiatric diagnoses. BRIEF-A sub-scales were within the average range (T’s= 47.9 - 52.9, SD’s [10.1 - 12.8]). Estimated premorbid IQ was average at 102.7 (11.4). Neuropsychological data revealed group performance within the average range on DSF and DSB (z’s= 0.00), TMT-A (z= -0.16), MR (z= -0.53), CPT (z= -0.39), and HVLT-R False Positives (z= 0.05) and Recognition Discriminability (z= -0.44). SRT (z= -0.70), CRT Accuracy (z= -1.37), TMT-B (z= -0.79), HVLT-R Total Recall and Percent Retained (z’s= -0.88), and Delayed Recall and True Positives (z’s= -1.27) were low average.Conclusions:In this sample of pre-surgical bariatric candidates with average intelligence, baseline evaluations revealed mild deficits in reaction time accuracy, visual motoric set-shifting, and verbal learning/memory. These deficits may be the result of microvascular changes in the brain secondary to physical compromise. Results provide additional insight into potential early-onset executive dysfunction, psychomotor slowing, and verbal learning/memory difficulties. In addition to these relative areas of neuropsychological weakness, candidates demonstrated relative strengths in attention, working memory, and visuospatial functioning. These insights provide pre-surgical evaluators with additional information to tailor recommendations and treatment approaches that foster surgical success. With a remote, concise, easy-to-administer battery of tests, routine neuropsychological assessment for bariatric surgery candidates is both a feasible and a useful tool for identifying areas of cognitive strengths and weaknesses. Documenting a patients’ cognitive baseline can assist with monitoring long-term vascular risk-factors and potential cognitive impairment.

90 Association Between Sedentary-To-Light Physical Activity Time Ratio and Cognitive Function in Bariatric Surgery Candidates

Objective:Class III obesity is associated with increased risk for cognitive impairment. Though hypothesized to be partially attributable to sedentary time (ST), past research examining the association between ST and cognitive function has produced mixed findings. One possible explanation is that studies do not typically account for the highly correlated and almost inverse relationship between ST and light intensity physical activity (LPA), such that ST displaces time engaging in LPA. Therefore, we aimed to evaluate whether: (1) higher ST-to-LPA time ratio associates with poorer performance across multiple cognitive domains in patients with Class III obesity seeking bariatric surgery; and (2) the associations differ by sex.Participants and Methods:Participants (N = 121, 21-65 years of age, BMI &gt; 40 kg/m2) scheduled for either Roux-en-Y Gastric Bypass (RYGB) or Sleeve Gastrectomy (SG) completed the NIH Toolbox, a computerized neuropsychological assessment battery and wore a waist-mounted ActiGraph monitor during waking hours for 7 days to measure minutes/day spent in ST, LPA, and moderate-to-vigorous physical activity (MVPA). A ratio of time spent in ST-to-LPA was calculated by dividing the percentage of daily wear time spent in sedentary behavior (SB) by the percentage of daily wear time spent in LPA.Results:On average, participants (mean age = 43.22 years old and BMI = 45.83 kg/m2) wore the accelerometer for 909±176 minutes/day and spent 642±174 minutes/day in ST, 254±79 minutes/day in LPA, and 14±13 minutes/day in MVPA. Mean daily ST-to-LPA time ratio was 2.81 ± 1.3 (0.73-7.11). Overall, bivariate Pearson correlations found no significant relationships between LPA and cognitive performance on any of the NIH Toolbox subtests (r values = -.002 to -.158, all p values &gt;.05). Additionally, bivariate Pearson correlations also found no significant relationships between daily ST-to-LPA time ratio and cognitive performance on any of the subtests (r values = .003 to .108, all p values &gt;.05). However, higher ST-to-LPA was associated with lower scores on the Dimensional Change Card Sort Test in women (r = -.26, p = .01).Conclusions:Results showed that participants’ mean daily time spent in ST was 2.5 times higher than that spent in LPA and a higher ratio of ST-to-LPA was associated with poorer set-shifting in women with Class III obesity. Future studies should look to clarify underlying mechanisms, particularly studies examining possible sex differences in the cognitive benefits of PA. Similarly, intervention studies are also needed to determine if increasing LPA levels for individuals with Class III obesity would lead to improved cognitive performance by means of reducing ST.

Analysis of semen parameters, and hormonal changes of FSH, LH, testosterone, and libido following bariatric surgery.

Although studies have shown that bariatric surgery can have a positive effect on the patient's sexual function, there are still disagreements and contradictions in this regard. The present study is aimed to evaluate semen parameters, hormonal changes of FSH, LH, testosterone, and libido following bariatric surgery. The present research as a prospective study was performed on 20 male candidates for bariatric surgery referred to Golestan and Aria hospitals in Ahvaz in 2021. Semen parameters (volume, count, motility, and the percentage of sperm with normal morphology), hormonal profile (including FSH, LH test hormones), and sexual function were evaluated using the International Index of Erectile Function (IIEF-5) questionnaire before and 6 months after the surgery. The results of this study indicated that semen parameters did not change significantly 6 months after surgery in comparison with before the surgery (P < 0.05). After the operation, just the total level of testosterone increased significantly (2.23 nmol/L vs. 2.74, P = 0.009). However, LH and FSH levels did not change significantly six months after surgery (P = 0.858 and P = 0.287). The results indicated significant improvement in IIEF score after the operation (P = 0.011). The findings of the present study indicated that the decrement of weight as a result of bariatric surgery had a favorable effect on the levels of serum testosterone and sexual performance, while semen parameters did not improve after surgery.

Results of the national registry of patients diagnosed with inflammatory bowel disease candidates for bariatric surgery (ReNacEIBar)

BackgroundOur aim is to carry out a national registry of patients with inflammatory bowel disease (IBD) who underwent bariatric surgery, as well as evaluate the results and management of this type of patients in the usual clinical practice. MethodsNational multicentric observational retrospective study, including patients, previously diagnosed with IBD who underwent bariatric surgery from January 2000 to December 2022. ResultsForty-one patients have been included: 43,9% previously diagnosed with ulcerative colitis, 57,3% Crohn's disease, and an indeterminate colitis (2,4%). The preoperative BMI was 45.8 ± 6,1 kg/m2. Among the bariatric surgeries, 31 (75,6%) sleeve gastrectomy, 1 (2,4%) gastric bypass and 9 (22%) one anastomosis gastric have been carried out. During the postoperative period, 9.8% complications have been recorded. BMI was 29,5 ± 4,7 kg/m2 and percent total weight lost was 33,9 ± 9,1% at 12 months. ConclusionsBariatric surgery in patients with inflammatory bowel disease can be considered safe and effective.

53 Change in Cerebral Metabolite Concentrations Following Bariatric Surgery

Objective:Obesity is associated with adverse effects on brain health, including increased risk for neurodegenerative diseases. Changes in cerebral metabolism may underlie or precede structural and functional brain changes. While bariatric surgery is known to be effective in inducing weight loss and improving obesity-related medical comorbidities, few studies have examined whether it may be able to improve brain metabolism. In the present study, we examined change in cerebral metabolite concentrations in participants with obesity who underwent bariatric surgery.Participants and Methods:35 patients with obesity (BMI &gt; 35 kg/m2) were recruited from a bariatric surgery candidate nutrition class. They completed single voxel 1H-proton magnetic resonance spectroscopy at baseline (pre-surgery) and within one year post-surgery. Spectra were obtained from a large medial frontal brain region. Tissue-corrected absolute concentrations for metabolites including choline-containing compounds (Cho), myo-inositol (mI), N-acetylaspartate (NAA), creatine (Cr), and glutamate and glutamine (Glx) were determined using Osprey. Paired t-tests were used to examine within-subject change in metabolite concentrations, and correlations were used to relate these changes to other health-related outcomes, including weight loss and glycemic control.Results:Bariatric surgery was associated with a reduction in cerebral Cho (f[34j = -3.79, p &lt; 0.001, d = -0.64) and mI (f[34] = -2.81, p &lt; 0.01, d = -0.47) concentrations. There were no significant changes in NAA, Glx, or Cr concentrations. Reductions in Cho were associated with greater weight loss (r = 0.40, p &lt; 0.05), and reductions in mI were associated with greater reductions in HbA1c (r = 0.44, p &lt; 0.05).Conclusions:Participants who underwent bariatric surgery exhibited reductions in cerebral Cho and mI concentrations, which were associated with improvements in weight loss and glycemic control. Given that elevated levels of Cho and mI have been implicated in neuroinflammation, reduction in these metabolites after bariatric surgery may reflect amelioration of obesity-related neuroinflammatory processes. As such, our results provide evidence that bariatric surgery may improve brain health and metabolism in individuals with obesity.

Interpersonal Characteristics and Binge Eating among Patients Pursuing Bariatric Surgery.

Preoperative binge eating behavior has been associated with difficulties in weight loss maintenance among patients pursuing bariatric surgery. However, limited data exists on the relationship between interpersonal difficulties and binge eating. To identify interpersonal factors linked with binge eating among bariatric surgery candidates. One hundred and seventeen adult bariatric surgery candidates (BMI = 42.2 ± 5.2) from three different hospitals completed questionnaires on the day of their bariatric committee meeting for operation approval. Binge eating was assessed using the Questionnaire on Eating and Weight Patterns-5 (QEWP-5) as a dichotomous variable. Self-esteem was measured using the Rosenberg Self-Esteem Scale (RSES), and interpersonal characteristics were evaluated using the short version of the Inventory of Interpersonal Problems (IIP-32). Sociodemographic variables (age, gender, income, education) and BMI were considered as confounders. Approximately 25% of bariatric surgery candidates reported experiencing binge eating episodes within the previous three months. Participants with binge eating exhibited significantly lower self-esteem and more interpersonal difficulties, particularly in the domains of aggressiveness and dependence, compared to those without binge eating. Logistic regression analysis revealed that aggressiveness was a significant predictor of binge eating in this sample. This study is the first, to the best of our knowledge, to investigate the relationship between interpersonal difficulties and binge eating among bariatric surgery candidates. The findings highlight the significant contribution of aggressiveness to binge eating and emphasize the importance of clinicians assessing patients' interpersonal functioning, particularly with regard to aggressiveness, as a factor that may contribute to the maintenance and occurrence of binge eating behaviors.

Bariatric Evaluation Through AI: a Survey of Expert Opinions Versus ChatGPT-4 (BETA-SEOV).

Recent advancements in artificial intelligence, such as OpenAI's ChatGPT-4, are revolutionizing various sectors, including healthcare. This study investigates the use of ChatGPT-4 in identifying suitable candidates for bariatric surgery and providing surgical recommendations to improve decision-making in obesity treatment amid the global obesity epidemic. We devised ten patient scenarios, thoughtfully encompassing a spectrum that spans from uncomplicated cases to more complex ones. Our objective was to delve into the decision-making process regarding the recommendation of bariatric surgery. From July 29th to August 10th, 2023, we conducted a voluntary online survey involving thirty prominent bariatric surgeons, ensuring that there was no predetermined bias in the selection of a specific type of bariatric surgery. This survey was designed to collect their insights on these scenarios and gain a deeper understanding of their professional experience and background in the field of bariatric surgery. Additionally, we consulted ChatGPT-4 in two separate conversations to evaluate its alignment with expert opinions on bariatric surgery options. In 40% of the scenarios, disparities were identified between the two conversations with ChatGPT-4. It matched expert opinions in 30% of cases. Differences were noted in cases like gastrointestinal metaplasia and gastric adenocarcinoma, but there was alignment with conditions like endometriosis and GERD. The evaluation of ChatGPT-4's role in determining bariatric surgery suitability uncovered both potential and shortcomings. Its alignment with experts was inconsistent, and it often overlooked key factors, emphasizing human expertise's value. Its current use requires caution, and further refinement is needed for clinical application.

Obezite Cerrahisi Hastalarında Obstrüktif Uyku Apne Sıklığı

Objective: Obesity is one of the most important risk factors and also consequences of obstructive sleep apnea (OSA). Weight loss and positive airway pressure therapy are the main approaches in the treatment of OSA. In this study, it was aimed to evaluate the prevalence of OSA in obesity patients scheduled for bariatric surgery.&#x0D; Methods: In the University Hospital Obesity Center, 141 consecutive patients who were candidates for bariatric surgery in 2015 were clinically evaluated preoperatively for sleep-related respiratory disorders. Preoperative polysomnographic examination was recommended to all cases.&#x0D; Results: Of 141 bariatric surgery candidates with a mean age of 37±10 years, and 103 (73%) were female. The mean body mass index of the cases was 46.9±6.4 kg/m2. Among the major symptoms of OSA, snoring was present in 119 (84.4%), daytime sleepiness in 63 (44.7%) and witnessed apnea in 49 (34.8%) patients. OSA was detected because AHI&gt;5/hour was found in 75.7% (84/111) of the patients who accepted the polysomnographic evaluation. 24.3% (27/111) of the cases who underwent polysomnography had non OSA, 29.7% (33/111) mild OSA, 17.1% (19/111) moderate OSA, and 28.8% (32 /111), severe OSA was detected. AHI was positively correlated with age (p=0.003), neck and waist diameter (p

Quality of Life, Pedobarographic Parameters, and Foot Disorders in Patients with Extreme Obesity: Preliminary Results on Changes After Bariatric Surgery with Gastric Bypass

PurposeObesity is a growing health problem that affects a high percentage of the population. In podiatry context, few studies have addressed obesity because most pedobarographic systems are unable to bear the weight of patients with obesity, making it difficult to examine and manage these patients. The objective of this study was analyzed the sociodemographic characteristics, quality of life, foot disorders, and pedobarographic parameters of patients with extreme obesity who are candidates for bariatric surgery and determine the changes after weight loss post-surgery.Materials and MethodsWe conducted a foot examination, a pedobarographic study using a Podoprint® pressure platform, and a quality of life questionnaire (EQ-5D) on 23 patients with extreme obesity and analyzed the changes 12–18 months after surgery in 11 of them.ResultsWe observed foot disorders, high plantar pressure, greater rearfoot contact, flat footprint, asymmetries, and alterations in toe contact. Almost 73.9% of participants said they had foot pain, 56.5% said they had impaired mobility, and more than 40% said they had limitations in carrying out daily activities and suffered from anxiety. After weight loss, we observed improved quality of life; more foot disorders; changes in total contact area, plantar pressures, barycenter, contact time, and footprint; decreased pain perception, walking problems and anxiety situations. Moreover, medication decreased, but they need to take more vitamins and calcium.ConclusionWeight loss improved the quality of life of the participating patients but altered their foot disorders. All parameters need regular reassessment to detect changes and modify initially prescribed treatments.Graphical
