Abstract
PURPOSE There is a lack of evidence for treatment of some conditions including complication management, suboptimal initial weight loss, recurrent weight gain, or worsening of a significant obesity complication after one anastomosis gastric bypass (OAGB). This study was designed to respond to the existing lack of agreement and to provide a valuable resource for clinicians by employing an expert-modified Delphi consensus method. METHODS Forty-eight recognized bariatric surgeons from 28 countries participated in the modified Delphi consensus to vote on 64 statements in two rounds. An agreement/disagreement among ≥ 70.0% of the experts was regarded to indicate a consensus. RESULTS A consensus was achieved for 46 statements. For recurrent weight gain or worsening of a significant obesity complication after OAGB, more than 85% of experts reached a consensus that elongation of the biliopancreatic limb (BPL) is an acceptable option and the total bowel length measurement is mandatory during BPL elongation to preserve at least 300-400 cm of common channel limb length to avoid nutritional deficiencies. Also, more than 85% of experts reached a consensus on conversion to Roux-en-Y gastric bypass (RYGB) with or without pouch downsizing as an acceptable option for the treatment of persistent bile reflux after OAGB and recommend detecting and repairing any size of hiatal hernia during conversion to RYGB. CONCLUSION While the experts reached a consensus on several aspects regarding revision/conversion surgeries after OAGB, there are still lingering areas of disagreement. This highlights the importance of conducting further studies in the future to address these unresolved issues.

The Weight of Bariatric Surgery: Wernicke-Korsakoff Syndrome after Vertical Sleeve Gastrectomy-A Case Series. J Pers Med 2024; 14:638. [PMID: 38929859 PMCID: PMC11204981 DOI: 10.3390/jpm14060638] [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: 04/18/2024] [Revised: 06/05/2024] [Accepted: 06/08/2024] [Indexed: 06/28/2024] Open
Abstract
In this case series, the simultaneous occurrence of Wernicke's encephalopathy (WE) and dry beriberi was reported in three patients who underwent vertical sleeve gastrectomy (VSG) between May 2021 and May 2023. All patients were obese women who underwent vertical sleeve gastrectomy (VSG) without immediate postoperative complications, but two weeks later, hyperemesis and subsequent encephalopathy with ocular movement abnormalities and weakness were observed over the following thirty days. Patients were referred to neurology, where due to the high suspicion of WE, thiamine replacement therapy was initiated; meanwhile, diagnostic neuroimaging and blood tests were conducted. Neurological and psychiatric evaluations and neuroconduction studies were performed to assess the clinical evolution and present sequelae. One year after diagnosis, all patients exhibited affective and behavioral sequelae, anterograde memory impairment, and executive functioning deficits. Two patients met the criteria for Korsakoff syndrome. Additionally, peripheral nervous system sequelae were observed, with all patients presenting with sensorimotor polyneuropathy. In conclusion, Wernicke's encephalopathy requires a high diagnostic suspicion for timely intervention and prevention of irreversible sequelae, which can be devastating. Therefore, raising awareness among medical professionals regarding the significance of this disease is essential.

Abstract
As a chronic, multifactorial disease, obesity is associated with a global social and economic burden. This condition significantly affects normal daily life and healthy social interactions, and shortens the life expectancy of patients. Compared with traditional weight-loss methods, the emergence of bariatric surgery has effectively improved the management of obesity. Furthermore, bariatric surgery can also inhibit the progression of multiple metabolic diseases. Despite its potential advantages, bariatric surgery cannot completely eliminate the possibility of weight regain and inadequate weight loss following the procedure. For super-obese patients, bariatric surgery still remains a surgical risk. In addition, the psychological problems and poor eating habits of obese patients also affect the weight loss effect and daily life. Thus, various adjuvant therapies involving multiple disciplines have attracted people's attention. Recently, it has been recognized that the combination of multiple interventions based on bariatric surgery is more advantageous than a single intervention in alleviating the complex and diverse metabolic diseases associated with obesity. The combined therapy considerably enhances the long-term efficacy of bariatric surgery and plays a positive role in the mental health and social lives of patients. In this article, the authors review this multidisciplinary combination therapy to enhance the current understanding of the treatment of obesity.

Abstract
Vascular diseases are the leading cause of death in Spain. Hypercholesterolemia is not only a cardiovascular risk factor, but also underlies the etiopathogenesis of atherosclerosis. Therefore, reducing LDL cholesterol (LDL-C) to the goals recommended by clinical practice guidelines, is essential to decrease the risk of vascular complications. Despite this, current LDL-C control is scarce, even in subjects with high and very high risk. This is mainly due to an insufficient intensification of lipid-lowering treatment. In this context, it is essential to prescribe the appropriate therapy, adjusted to patient's needs based on their LDL-C and their vascular risk. Rosuvastatin, alone or in combination with ezetimibe, provides intensive LDL-C reductions (up to 50-55% and 60-75%, respectively), with a low risk of side effects and in an efficient manner, in patients both without and with established atherosclerotic vascular disease.

Abstract
INTRODUCTION Outcomes of long-term (5-10-year) weight loss have not been investigated thoroughly and the role of pre-operative weight loss on long-term weight loss, among other factors, are unknown. Our regional bariatric service introduced a 12 week intensive pre-operative information course (IPIC) to optimise pre-operative weight loss and provide education prior to bariatric surgery. The present study determines the effect of pre-operative weight loss and an intense pre-operative information course (IPIC), on long-term weight outcomes and sustained weight loss post-bariatric surgery. METHODS Data were collected prospectively from a bariatric center (2008-2022). Excess weight loss (EWL) ≥ 50% and ≥ 70% were considered outcome measures. Survival analysis and logistic regression identified variables associated with overall and sustained EWL ≥ 50% and ≥ 70%. RESULTS Three hundred thirty-nine patients (median age, 49 years; median follow-up, 7 years [0.5-11 years]; median EWL%, 49.6%.) were evaluated, including 158 gastric sleeve and 161 gastric bypass. During follow-up 273 patients (80.5%) and 196 patients (53.1%) achieved EWL ≥ 50% and ≥ 70%, respectively. In multivariate survival analyses, pre-operative weight loss through IPIC, both < 10.5% and > 10.5% EWL, were positively associated with EWL ≥ 50% (HR 2.23, p < 0.001) and EWL ≥ 70% (HR 3.24, p < 0.001), respectively. After a median of 6.5 years after achieving EWL50% or EWL70%, 56.8% (154/271) had sustained EWL50% and 50.6% (85/168) sustained EWL70%. Higher pre-operative weight loss through IPIC increased the likelihood of sustained EWL ≥ 50% (OR, 2.36; p = 0.013) and EWL ≥ 70% (OR, 2.03; p = 0.011) at the end of follow-up. CONCLUSIONS IPIC and higher pre-operative weight loss improve weight loss post-bariatric surgery and reduce the likelihood of weight regain during long-term follow-up.

Abstract
Background: We previously described sleeve gastrectomy with jejunoileal bypass (SGJIB) as promising novel technique for the surgical treatment of obesity Methods: A retrospective analysis of a prospective database in a Private Practice of Alimentary Tract Surgery in São Paulo, Brazil. We analyzed 176 patients with 60 months of follow-up, 74 of whom underwent Vertical Sleeve Gastrectomy with Jejunoileal Bypass (VSG-JIB) (50 women and 24 men) with a mean age of 38 years and a mean body mass index (BMI) of 40 kg/m2, and 102 patients underwent Roux-en-Y gastric bypass (RYGB) (90 women and 12 men) with a mean age of 36.5 years and a mean BMI of 39.73 kg/m2. Results: There was no statistically significant difference in long-term weight loss between the two groups. The rate of postoperative complications immediately after surgery was similar, but there was a tendency toward less severe complications in the SGJIB cohort. Conclusion: Sleeve gastrectomy with jejunoileal bypass is a novel surgical procedure for weight loss with comparable efficacy and safety compared with laparoscopic RYGB.

A Systematic Review and Meta-Analysis of Free Triiodothyronine (FT3) Levels in Humans Depending on Seasonal Air Temperature Changes: Is the Variation in FT3 Levels Related to Nonshivering Thermogenesis? Int J Mol Sci 2023; 24:14052. [PMID: 37762355 PMCID: PMC10531421 DOI: 10.3390/ijms241814052] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2023] [Revised: 09/08/2023] [Accepted: 09/11/2023] [Indexed: 09/29/2023] Open
Abstract
Thyroid hormones play a crucial role in regulating normal development, growth, and metabolic function. However, the controversy surrounding seasonal changes in free triiodothyronine (FT3) levels remains unresolved. Therefore, the aim of this study was to conduct a systematic review and meta-analysis of variations in FT3 levels in relation to seasonal air temperatures in the context of current knowledge about its role in nonshivering thermogenesis. Ten eligible articles with a total of 336,755 participants were included in the meta-analysis. The studies were categorized into two groups based on the air temperature: "Cold winter", where the winter temperature fell below 0 °C, and "Warm winter", where the winter temperature was above 0 °C. The analysis revealed that in cold regions, FT3 levels decreased in winter compared to summer (I2 = 57%, p < 0.001), whereas in warm regions, FT3 levels increased during winter (I2 = 28%, p < 0.001). These findings suggest that seasonal variations in FT3 levels are likely to be influenced by the winter temperature. Considering the important role of the FT3 in the nonshivering thermogenesis process, we assume that this observed pattern is probably related to the differences in use of thyroid hormones in the brown adipose tissue during adaptive thermogenesis, which may depend on intensity of cold exposure.

Abstract
As the association between obesity and bone health remains controversial in children and adolescents, we investigate the effects of obesity parameters on bone mineral density (BMD) in 2060 Korean adolescents who participated in the 2008-2011 Korea National Health and Nutrition Examination Survey (KNHANES). Multiple regression analysis and analysis of covariance (ANCOVA) were conducted to examine both the linear and non-linear associations between total-body-less-head (TBLH) BMD and four obesity parameters: body mass index, waist circumference, waist-to-height ratio, and total-body fat mass (FM). In a multiple linear regression analysis adjusted for age, menarcheal status (in females only), and total-body lean mass, there was no significant linear association between obesity parameters and TBLH BMD, except for total-body FM in males. However, upon adding a second-order polynomial term for each obesity parameter, a significant quadratic relationship between all obesity parameters and TBLH BMD was observed, with the corresponding quadratic term being negative. The results of ANCOVA also revealed an inverted U-shaped relationship between each obesity parameter and TBLH BMD. Our findings suggest the existence of an optimal range of obesity parameters for developing or maintaining optimal bone health in Korean Adolescents. Deviation from this range, in either direction (being underweight or having obesity), may compromise bone health.

Abstract
Obesity has emerged as a pressing concern in contemporary society, prompting an increase in bariatric surgery (BS) procedures for severe obesity management. Post-bariatric weight loss might cause complications, such as a reduction in the soft tissue surrounding the Eustachian tube, potentially affecting its function. This cohort prospective study, conducted between May and December 2022, aimed to assess the impact of post-bariatric acute weight loss on Eustachian tube function. A total of 54 cases of bariatric surgery and 157 control subjects were included in the study. Data on socio-demographics, weight, and the type of bariatric surgery were collected for the study group. ET function was assessed using the Eustachian Tube Dysfunction Questionnaire (ETDQ-7). Approximately 55% of the participants fell within the age range of 18-25 years, with the majority (91.4%) having not undergone bariatric surgery. Conversely, participants who underwent BS were significantly more prevalent in the older age groups, specifically those over 50, between 40-50, and 31-40 years (p<0.001). Our sample consisted of 82.5% females and 17.5% males, with BS being significantly more common among male subjects (45.9%) compared to females (21.3%) (p=0.002). The mean total ETDQ-7 in control subjects was significantly higher (11.29±5.49) compared to those who had BS (9.11±4.09). Moreover, when comparing the ETDQ-7 between subjects who had BS and the control group, no statistically significant differences were observed in the total ETDQ-7 score and across all seven items within the ETDQ-7. Based on these findings, bariatric surgery did not have a major effect on ET function.
