ABSTRACT
INTRODUCTION: Laparoscopic sleeve gastrectomy (LSG) is currently the most common bariatric procedure performed in adolescents and young adults in the United States (USA), but there are limited data available on long-term postoperative weight outcomes in these patients. This single-institution US study follows longitudinal weight data in a diverse group of patients undergoing LSG at age 25 years or younger. METHODS: We retrospectively reviewed records of all patients 25 years or younger who underwent LSG at our institution between 2013 and 2020. All weight data documented in the medical record through January 2023 was included. We calculated weight change postoperatively as percent total weight loss (%TWL) relative to preoperative weight. RESULTS: One hundred forty-one patients underwent LSG, at a mean age of 23.1 years. Within this cohort, 56.1% identified as non-Hispanic Black or Hispanic, and 39.7% had private health insurance. The mean %TWL at weight nadir was 28.5% at a mean of 1.35 years postoperatively. The mean long-term %TWL (in patients with ≥ 4 years of follow-up) was 11.8% at a mean of 5.6 years postoperatively, with 43 of the 84 patients with long-term weight data (51%) within 10% of their preoperative weight at most recent follow-up. CONCLUSION: Adolescents and young adults undergoing LSG at our institution had weight nadir comparable to published results during the first 1 to 2 years postoperatively, but the majority developed significant weight recurrence over the ensuing years. Our findings highlight the need for adjuvant weight loss strategies to improve the durability of weight outcomes after LSG in this population.

The study's aim was not only to use quality improvement system techniques to improve patient care specifically for bleeding but also to track other adverse outcomes. Key drivers were identified and mapped to interventions, namely venous thromboembolism prophylaxis, root cause analysis, indications conference, and operative technique standardization. Bleeding was reduced by 88%, and overall postoperative complications also fell by 63%. A targeted quality improvement project not only was effective in improving outcomes for the specific aim of bleeding but also resulted in improvement for other patient outcomes.

BACKGROUND: Physical activity (PA) is important for the long-term health and weight management of patients who undergo metabolic and bariatric surgery (MBS). However, the roles of exercise professionals in MBS settings have not been systematically determined. OBJECTIVES: To investigate: (1) who are the professionals implementing PA programming in MBS clinical settings; and (2) what patient-centric tasks do they perform? SETTING: Clinical and academic exercise settings worldwide. METHODS: This multimethod study included a scoping review of PA programs in MBS described in the research literature. Data about job tasks were extracted and provided to 10 experts to sort into categories. Cluster analysis was utilized to find the hierarchical structure of tasks. A Delphi process was used to agree on a final model. RESULTS: The majority of PA professionals were exercise physiologists in the USA and physiotherapists or other types of exercise professionals elsewhere. Forty-three tasks were identified, the most reported being supervision of exercise, fitness testing, and exercise prescription. Seven higher-order categories were determined: (1) Exercise-related health assessment, (2) Body composition and physical fitness assessment, (3) Lifestyle physical activity and sedentary behavior assessment, (4) Education, instruction, and prescription, (5) Exercise monitoring, (6) Behavioral counseling and psychosocial support, and (7) Dietary support. The following statements were rated an average of 9.0, classifying them as "imperative": 1) "Pre- and postoperative PA/exercise guidelines for MBS patients are needed", 2) "MBS programs need to include PA/exercise as part of multidisciplinary care". CONCLUSIONS: The expert group reached a consensus on 7 major classifications of job tasks for the exercise professional. It is important for governing medical associations across the world to formally recognize experienced exercise professionals as playing pivotal roles in continuing, multidisciplinary care for MBS patients. These findings also provide evidence-based information in the effort to solidify these positions within the greater context of healthcare.

OBJECTIVE: A universal resident robotic surgery training pathway that maximizes proficiency and safety has not been defined by a consensus of surgical educators or by surgical societies. The objective of the Robotic Surgery Education Working Group was to develop a universal curriculum pathway and leverage digital tools to support resident education. DESIGN: The two lead authors (JP and YN) contacted potential members of the Working Group. Members were selected based on their authorship of peer-review publications, their experience as minimally invasive and robotic surgeons, their reputations, and their ability to commit the time involved to work collaboratively and efficiently to reach consensus regarding best practices in robotic surgery education. The Group's approach was to reach 100% consensus to provide a transferable curriculum that could be applied to the vast majority of resident programs. SETTING: Virtual and in-person meetings in the United States. PARTICIPANTS: Eight surgeons (2 females and 6 males) from five academic medical institutions (700-1541 beds) and three community teaching hospitals (231-607 beds) in geographically diverse locations comprised the Working Group. They represented highly specialized general surgeons and educators in their mid-to-late careers. All members were experienced minimally invasive surgeons and had national reputations as robotic surgery educators. RESULTS: The surgeons initially developed and agreed upon questions for each member to consider and respond to individually via email. Responses were collated and consolidated to present on an anonymized basis to the Group during an in-person day-long meeting. The surgeons self-facilitated and honed the agreed upon responses of the Group into a 5-level Robotic Surgery Curriculum Pathway, which each member agreed was relevant and expressed their convictions and experience. CONCLUSIONS: The current needs for a universal robotic surgery training curriculum are validated objective and subjective measures of proficiency, access to simulation, and a digital platform that follows a resident from their first day of residency through training and their entire career. Refinement of current digital solutions and continued innovation guided by surgical educators is essential to build and maintain a scalable, multi-institutional supported curriculum.

BACKGROUND: While some bariatric surgery outcomes vary by race/ethnicity, less is known about racial/ethnic differences in loss-of-control (LOC) eating and psychosocial outcomes post-surgery. OBJECTIVE: This prospective study examined and extended initial short-term findings regarding racial differences in post-bariatric surgery LOC eating and weight loss to longer-term outcomes through 24-month follow-ups. SETTING: Academic medical center in the United States. METHODS: Participants were 140 patients (46.4% non-White) in a 3-month randomized, controlled trial for LOC eating performed about 6 months after bariatric surgery. Participants were reassessed at 6, 12, 18, and 24 months after treatment ended (about 33 mo after surgery). Doctoral assessors administered the Eating Disorder Examination-Bariatric Surgery Version interview to assess LOC eating and eating-disorder psychopathology at 12- and 24-month follow-ups. The Beck Depression Inventory II was repeated, and measured weight was obtained at all follow-ups. RESULTS: White patients had significantly greater percent excess weight loss at all follow-ups than non-White patients (p < .03). White patients reported significantly more LOC eating at 12- (p = .004) and 24-month (p = .024) follow-ups and significantly greater eating disorder psychopathology at 12-month follow-up (p < .028). Racial groups did not differ significantly in eating disorder psychopathology at 24-month follow-ups or in Beck Depression Inventory II depression scores at any follow-ups. CONCLUSIONS: Our findings suggest that among patients with LOC eating after bariatric surgery, non-White patients attain a lower percent excess weight loss than White patients but have comparable or better outcomes in LOC eating, associated eating disorder psychopathology, and depression over time.

The aims of this study were to assess whether completion of the emergency department (ED) Big 6 interventions (provision of pain relief, screening for delirium, early warning score (EWS) system, full blood investigation and electrocardiogram, intravenous fluids therapy, and pressure area care) in those presenting with an acute hip fracture were associated with mortality risk and length of acute hospital stay. A retrospective cohort study was undertaken. All patients aged ≥50 years that were admitted with a hip fracture via the ED at a single centre during a 42-month period were included. A total of 3613 patients (mean age 80.9; 71% female) were included. The mean follow up was 607 (range 240 to 1542) days. A total of 1180 (32.7%) patients had all six components completed. Pain relief (90.8%) was the most frequently completed component and pressure area assessment (57.6%) was the least. Completion of each of the individual Big 6 components, except for pressure areas assessment, were associated with a significantly (p ≤ 0.041) lower mortality risk at the 90-days, one-year and final follow-up. The completion of all components of the Big 6 was associated with a significantly (2.4 hours, p = 0.002) shorter time to theatre. Increasing number of Big 6 components completed were independently associated with a lower mortality risk: when all six were completed, the hazard ratio was 0.64 (95% CI 0.52 to 0.78, p < 0.001). Completion of an increasing number of Big 6 components was independently associated with shorter length of hospital stay and completion of all six was associated with a 2.3 (95% CI 0.9 to 3.8)-day shorter acute stay. The findings provide an evidence base to support the ongoing use of the Big 6 in the ED.

ABSTRACT
This study examined baseline patient characteristics as predictors of early weight loss, defined as any weight loss within the first month of treatment, among patients receiving adjunctive behavioural treatments for loss-of-control (LOC) eating about 6 months after bariatric surgery. Participants were 126 patients in a treatment trial for LOC-eating (roughly 6 months postoperatively) categorized by early weight change following 1 month of treatment. Early weight-loss, defined as any weight loss following 1 month of treatment, and weight-gain, defined as any weight gain, groups were compared on sociodemographic and clinical variables assessed using a battery of reliably administered diagnostic and clinical interviews and established self-report measures, and on surgery-related variables (time since surgery, percent total [%TWL], and percent excess weight loss). Most patients (n = 99; 78.6%) lost weight after the first month of adjunctive treatments. Black patients (n = 24; 61.5%) were significantly less likely to achieve early weight loss compared to patients identifying as White (n = 60; 83%) or 'other' (n = 15; 100%) which was not predicted by any other sociodemographic variable. Severity of eating-disorder psychopathology, psychiatric comorbidity, and a broad range of psychosocial measures were not significantly predictive of early weight changes. Duration since surgery and percent weight loss from time of surgery to study enrolment 6-months post-surgery differed by early weight-loss and weight-gain groups. Findings suggest that among post-bariatric surgery patients receiving adjunctive behavioural treatments for LOC-eating, baseline patient characteristics, aside from race and surgery-related variables, do not predict early weight loss.

Background: Preoperative patient evaluation and optimization in a preoperative evaluation center (PEC) has been shown to improve operating room (OR) efficiency and patient care. However, performing preoperative evaluation on all patients scheduled for surgery or procedure would be time- and resource-consuming. Therefore, appropriate patient selection for evaluation at PECs is one aspect of improving PEC efficiency. In this study, we evaluate the effect of an enhanced preoperative evaluation process (PEP), utilizing a nursing triage phone call and information technology (IT) optimizations, on PEC efficiency and the quality of care in bariatric surgery patients. We hypothesized that, compared to a traditional PEP, the enhanced PEP would improve PEC efficiency without a negative impact on quality. Methods: The study was a retrospective cohort analysis of 1550 patients from January 2014 to March 2017 at a large, tertiary care academic health system. The study was a before/after comparison that compared the enhanced PEP model to the traditional PEP model. The primary outcome was the efficiency of the PEC, which was measured by the reduction of in-person patient visits at the PEC. The secondary outcome was the quality of care, which was measured by delays, cancellations, and the need for additional testing on the day of surgery (DOS). Results: The enhanced PEP improved the primary outcome of efficiency, as evident by an 80% decrease in in-person patient visits to the PEC. There was no reduction in the secondary outcome of the quality of care as measured by delays, cancellations, or the need for additional testing on the DOS. The implementation of the enhanced PEP did not result in increased costs or resource utilization. Conclusions: The enhanced PEP in a multi-disciplinary preoperative process can improve the efficiency of PEC for bariatric surgery patients without any decrease in the quality of care. The enhanced PEP process can be implemented without an increase in resource utilization and can be particularly useful during the COVID-19 pandemic.
ABSTRACT
BACKGROUND: Loss-of-control (LOC)-eating postoperatively predicts suboptimal longer-term outcomes following bariatric surgery. This study examined longer-term effects through 24-month follow-ups after completing treatments in a randomized controlled trial testing guided-self-help treatments (cognitive-behavioral therapy [gshCBT] and behavioral weight-loss [gshBWL]) and control (CON) delivered postoperatively for LOC-eating. METHODS: 140 patients with LOC-eating 6 months after bariatric surgery were randomized (5:5:2 ratio) to 3-months of gshCBT (n = 56), gshBWL (n = 60), or CON (n = 24) delivered by trained allied-health clinicians. Independent assessments were performed throughout/after treatments and at 6-, 12-, 18-, and 24-month follow-ups; 83% of patients were assessed at 24-month follow-up. RESULTS: Intention-to-treat analyses comparing the three groups (gshCBT vs. gshBWL vs. CON) in LOC-eating abstinence at posttreatment (30%, 27%, 38%), 12-month follow-up (34%, 32%, 42%), and 24-month follow-up (45%, 32%, 38%) revealed no significant differences. Mixed-models revealed significantly reduced LOC-eating frequency through posttreatment, no significant changes in LOC-eating frequency during follow-up, and no differences between the three groups. Weight reduced significantly, albeit modestly, through posttreatment but increased significantly and substantially during follow-ups, with no differences between groups. CONCLUSIONS: Overall, the 12-week scalable guided-self-help treatments did not differ from each other or control, were associated with significantly reduced frequency of LOC-eating and modest weight loss at posttreatment but were followed by significant weight gain during the 24-month follow-up. Weight gain was substantial and nearly universal whereas the frequency of LOC-eating did not change over time (i.e., LOC-eating reductions and abstinence rates were well maintained through 24-moth follow-ups). Patients with postoperative LOC-eating require more intensive adjunctive treatments. PUBLIC SIGNIFICANCE: Loss-of-control (LOC) eating postoperatively predicts poorer bariatric surgery outcomes and the longer-term effects of postoperative adjunctive postoperative interventions for LOC eating are unknown. In this 24-month follow-up of a controlled study of scalable guided-self-help treatments and a control condition, improvements in LOC-eating frequency, eating-disorder psychopathology, and depression during treatment were maintained well, with no differences between the three groups. Proportion of patients achieving abstinence from LOC-eating at the 24-month follow-up ranged from 38% to 45% across the three groups. In contrast, weight increased significantly during the 24-month follow-ups, with no differences between the three groups. Findings suggest LOC-eating following bariatric surgery might represent a "marker" for a subgroup of patients that are at risk for substantial weight gains over time. LOC eating following bariatric surgery is challenging to treat with low-intensity scalable treatments and may require more intensive specialist treatments.

In a response to a research paper which analyses how US newspapers represent young people and parents in their response to climate crisis, this commentary observes that the newspapers achieve some advantage in selecting frames, which privilege adult behaviour at the expense of actions taken by young people. It suggests that one effect of newspapers' choice to frame teens' awareness and activities surrounding climate change in disparaging terms may be to increase any eco-anxiety by devaluing it. It argues that this is done to benefit the newspapers by supporting rather than challenging the schema of their adult readers, following a commercial rather than societal agenda. A subsidiary effect may be to drive younger people away from mainstream media, which fails to represent their viewpoint and towards misinformation and disinformation from unreliable sources.

PURPOSE: Post-operative loss-of-control (LOC)-eating is a negative prognostic indicator for long-term outcomes following bariatric surgery. Emerging research suggests that night eating might also be associated with poorer post-operative outcomes. This study examined the co-occurrence and clinical features of night eating in patients with LOC-eating following bariatric surgery. METHODS: Participants were 131 adults who sought treatment for eating/weight concerns 6 months following sleeve gastrectomy. The Eating Disorder Examination (EDE) interview (Bariatric-Surgery-Version) assessed LOC-eating, regular night eating (at least weekly), and eating-disorder psychopathology. Participants completed the Night Eating Questionnaire (NEQ), Beck Depression Inventory (BDI-II), and the Pittsburgh Sleep Quality Index (PSQI). RESULTS: Approximately, 15% met screening criteria for night-eating syndrome based on the NEQ. Greater NEQ scores were associated significantly with race, lower percent total weight loss (%TWL), and greater EDE, BDI-II, and PSQI scores. Similar results were observed when comparing groups with regular night eating (21.4%) versus without (78.6%); adjusting for race and %TWL revealed similar findings. DISCUSSION: In post-bariatric patients with LOC-eating, 15% likely had night-eating syndrome and 21.4% engaged in regular night-eating behavior. The co-occurrence of LOC-eating and regular night eating following sleeve gastrectomy may represent a more severe subgroup with elevated psychopathology, poorer sleep and %TWL. LEVEL OF EVIDENCE: Level III, evidence obtained from well-designed cohort or case-control analytic studies.

In this study, we use molecular genetic approaches to clarify the role of the Hedgehog (Hh) pathway in regulating the blood-brain/spinal cord barrier (BBB) in the adult mouse central nervous system (CNS). Our work confirms and extends prior studies to demonstrate that astrocytes are the predominant cell type in the adult CNS that transduce Hh signaling, revealed by the expression of Gli1, a target gene of the canonical pathway that is activated in cells receiving Hh, and other key pathway transduction components. Gli1+ (Hh-responsive) astrocytes are distributed in specific regions of the CNS parenchyma, including layers 4/5/6 of the neocortex, hypothalamus, thalamus, and spinal cord, among others. Notably, although BBB properties in endothelial cells are normally regulated by both paracellular and transcellular mechanisms, conditional inactivation of Hh signaling in astrocytes results in transient, region-specific BBB defects that affect transcytosis but not paracellular diffusion. These findings stand in contrast to prior studies that implicated astrocytes as a source of Sonic hedgehog that limited extravasation via both mechanisms [J. I. Alvarez et al., Science 334, 1727-1731 (2011)]. Furthermore, using three distinct Cre driver lines as well as pharmacological approaches to inactivate Hh-pathway transduction globally in CNS astrocytes, we find that these specific BBB defects are only detected in the rostral hypothalamus and spinal cord but not the cortex or other regions where Gli1+ astrocytes are found. Together, our data show that Gli1+ Hh-responsive astrocytes have regionally distinct molecular and functional properties and that the pathway is required to maintain BBB properties in specific regions of the adult mammalian CNS.

Bariatric surgery, initially understood as restricting or bypassing the amount of food that reaches the stomach to reduce food intake and/or increase malabsorption of food to promote weight loss, is now recognized to also affect incretin signaling in the gut and promote improvements in system-wide metabolism. Positron emission tomography (PET) is an imaging technique whereby patients are injected with picomolar concentrations of radioactive molecules, below the threshold of having physiological effects, to measure spatial distributions of blood flow, metabolism, receptor, and enzyme pharmacology. Recent advances in both whole-body PET imaging and radioligand development will allow for novel research that may help clarify the roles of peripheral and central receptor/enzyme systems in treating obesity with bariatric surgery.

OBJECTIVE: Loss-of-control (LOC) eating postoperatively is a consistent predictor of suboptimal longer-term bariatric surgery outcomes. This randomized controlled trial examined the effectiveness of two guided self-help treatments (cognitive behavioral therapy [gshCBT] and behavioral weight loss [gshBWL]) compared with a control (CON) for reducing LOC eating and weight. METHODS: A total of 140 patients with recurrent LOC eating approximately 6 months after bariatric surgery were randomly assigned (5:5:2 ratio) to one of three conditions: gshCBT (n = 56), gshBWL (n = 60), or CON (n = 24). Three-month treatments were delivered by trained allied health clinicians to increase generalizability to bariatric surgery settings. Independent assessments were performed by doctoral research-clinicians using established interviews/measures; posttreatment outcomes were obtained for 89% of patients. RESULTS: Mixed models revealed significant improvements for LOC eating frequency and weight loss but no significant differences between treatments; race neither predicted (main effect) nor moderated (interaction effect) treatment outcomes. Intent-to-treat categorical analyses of abstinence from LOC eating (30% for gshCBT, 27% for gshBWL, 38% for CON) and proportion attaining 5% weight loss (20%, 22%, 17%) revealed no significant differences between treatments; non-White participants had a higher proportion achieving LOC eating abstinence but a lower proportion attaining 5% weight loss compared with White participants. CONCLUSIONS: In this 12-week randomized controlled trial following bariatric surgery, significant LOC eating reductions and weight loss did not differ significantly between treatments. Race was associated with posttreatment categorical outcomes.

BACKGROUND: The American Society for Metabolic and Bariatric Surgery has released a Bariatric Surgical Risk/Benefit Calculator, an online tool with which patients and providers can input patient preoperative information and predict their 1-year weight loss. We seek to validate our institutional data with the national database and investigated patient factors that influence lack of treatment effect after bariatric surgery. MATERIALS AND METHODS: A retrospective review of all prospectively collected data of bariatric surgeries performed at Yale New Haven Hospital from 2017 to 2018 was conducted. By entering data into the MBSAQIP Calculator, the 1-year predicted Body Mass Index was calculated and compared to the actual weight loss. Statistical analysis was performed using an unpaired t-test with Welch's correction (Prism 8, GraphPad). RESULTS: The average difference between the actual and predicted weight loss at 1-year for 327 patients was 3.6 BMI points. When the actual weight loss was compared to predicted BMI at 1 year, a high correlation was found (R = 0.6, P = 0.003). We examined the outliers with a comparison of weight loss for those patients who's BMI fell within 5 points of the predicted versus those whose BMI recorded above 5. It was discovered those patients who had higher than 5 BMI points than predicted, had higher preoperative BMI (46.1 vs 43.6, P = 0.008). CONCLUSIONS: The MBSAQIP calculator is a useful tool to guide surgeons with decision-making and informed consent. Our institution's 1-year weight loss data correlated closely with that predicted. From the outliers, we found that patients who did not meet the predicted weight loss had significantly higher preoperative BMI. This may alter preoperative discussions with class 3 or over obese patients regarding expected weight loss and warrant investigations with the national database to develop modifications of the calculator.

OBJECTIVE: Bariatric surgery affects the quantity of food individuals can eat, yet some individuals still experience loss of control (LOC) while eating. This cross-sectional study examined a new classification system for binge/LOC eating following bariatric surgery. METHODS: A total of 168 individuals who underwent bariatric surgery 6 months earlier and reported LOC eating were administered the Eating Disorder Examination-Bariatric Surgery Version interview and self-report measures of depressive symptoms, functional impairment, and physical and mental health-related quality of life. Three groups were created based on the largest LOC-eating episode determined by the Eating Disorder Examination-Bariatric Surgery Version interview as follows: (1) "traditional" objective binge-eating episodes, defined as eating unusually large quantities of food while having LOC; (2) "bariatric-objective binge eating," meaning unusually large quantities for postsurgical bariatric patients with LOC; and (3) "bariatric-subjective binge eating," meaning small quantities of food with LOC after surgery. RESULTS: In total, 75% (n = 126) met criteria for the bariatric-objective binge episodes group, 10% (n = 17) met criteria for the traditional objective binge-eating group, and 15% (n = 25) met criteria for the bariatric-subjective binge episodes group. The three groups differed significantly, with a graded pattern by binge size, in global eating-disorder psychopathology, depressive symptoms, and functional impairment but not quality of life. CONCLUSIONS: These findings provide empirical support for a new classification system for bariatric binge/LOC eating. Binge size was associated with distinct psychopathology. Longitudinal follow-up is needed to ascertain effects on clinical outcomes.
