Abstract
AbstractBackgroundCombination anti‐obesity medications (AOMs) to treat postoperative bariatric surgery weight regain have limited data on their use in the clinical setting. Understanding the optimal treatment protocol in this cohort will maximize weight loss outcomes.MethodsA retrospective review of bariatric surgery patients (N = 44) presenting with weight regain at a single academic multidisciplinary obesity center who were prescribed AOM(s) plus intensive lifestyle modification for 12 months.ResultsAge: 28–76 years old, 93% female, mean weight 110.2 ± 20.3 kg, BMI 39.7 ± 7.4 kg/m2, presenting 5.2 ± 1.6 years post‐bariatric surgery [27 (61.4%), 14 (31.8%), and 3 (6.8%) laparoscopic Roux‐en‐Y gastric bypass (RYGB), laparoscopic vertical sleeve gastrectomy (VSG), and open RYGB, respectively], with 15.1 ± 11.1 kg mean weight gain from nadir. Mean weight loss after medical intervention at 3‐, 6‐, and 12‐month time points was 4.4 ± 4.6 kg, 7.3 ± 7.0 kg, and 10.7 ± 9.2 kg, respectively. At 12 months, individuals prescribed 3 or more AOMs lost more weight than those prescribed one (−14.5 ± 9.0 kg vs. −4.9 ± 5.7 kg, p < 0.05) irrespective of age, gender, number of comorbidities, initial weight or BMI, type of surgery, or GLP1 use. RYGB patients lost less weight overall (7.4% vs. 14.8% VSG respectively; p < 0.05).ConclusionsCombination AOMs may be needed to achieve optimal weight loss results to treat post‐operative weight regain.

Abstract
PURPOSE OF REVIEW Rates of obesity and associated comorbidities are higher among Black and Latino adults compared to white adults. We sought to provide an overview of both structural and individual factors contributing to obesity inequities and synthesize available evidence regarding treatment outcomes in Black and Latino adults, with an eye towards informing future directions. RECENT FINDINGS Obesity disparities are influenced by myriad systemic issues, yet the vast majority of interventions target individual-level factors only, and most behavioral treatments fail to target drivers beyond eating and physical activity. Extant treatments are not equally accessible, affordable, or effective among Black and Latino adults compared with white counterparts. Asset-based, culturally relevant interventions that target the root causes of obesity and address intersectional stress-designed in partnership with intended beneficiaries-are urgently needed. Treatment trials must improve enrollment of Black and Latino adults and report treatment outcomes by race and ethnicity.

Bariatric surgery practice patterns among pediatric surgeons in the United States. J Pediatr Surg 2022; 57:887-891. [PMID: 35927071 DOI: 10.1016/j.jpedsurg.2022.07.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/19/2022] [Revised: 06/18/2022] [Accepted: 07/04/2022] [Indexed: 11/22/2022]
Abstract
BACKGROUND Metabolic and bariatric surgery (MBS) in adolescents has been shown to be safe and effective, but current practice patterns are variable and poorly understood. The aim of this study is to assess current MBS practice patterns among pediatric surgeons in the United States. METHODS American Pediatric Surgical Association members were surveyed on current bariatric surgery practices. RESULTS Four hundred and three (40%) surgeons out of a total of 1013 pediatric surgeons responded to the survey. Only 2 respondents had additional training in MBS (0.5%). One hundred thirty-two (32.6%) report that their practice participates in metabolic and bariatric surgery, with 123 (30.4%) having a specific partner specializing in MBS. Most respondents (92%) stated that they believe high volume is associated with better outcomes with regard to MBS. Only 17 (4.2%) surgeons performed a metabolic and bariatric surgery in the last year. All routinely perform sleeve gastrectomy as their primary procedure. Most (82%) perform procedures with an additional surgeon, either another pediatric surgeon (47%) or an adult bariatric surgeon (47%). All pediatric bariatric surgeons responded that they believe high volume led to better outcomes. Adolescent MBS programs most commonly included pediatric nutritionists (94%), pediatric psychologists (94%), clinical nurses (71%), clinical coordinators (59%), pediatric endocrinologists (59%), and exercise physiologists (52%). CONCLUSION Only 17 (4.2%) respondents had performed a metabolic and bariatric surgery in the past year, and few of those had additional training in MBS. Future work is necessary to better understand optimal practice patterns for adolescent metabolic and bariatric surgery. TYPE OF STUDY Review article. LEVEL OF EVIDENCE Level III.

Abstract
Importance Bariatric surgery is the most effective treatment for severe obesity; yet it is unclear whether the long-term safety and comparative effectiveness of these operations differ across racial and ethnic groups. Objective To compare outcomes of Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) across racial and ethnic groups in the National Patient-Centered Clinical Research Network (PCORnet) Bariatric Study. Design, Setting, and Participants This was a retrospective, observational, comparative effectiveness cohort study that comprised 25 health care systems in the PCORnet Bariatric Study. Patients were adults and adolescents aged 12 to 79 years who underwent a primary (first nonrevisional) RYGB or SG operation between January 1, 2005, and September 30, 2015, at participating health systems. Patient race and ethnicity included Black, Hispanic, White, other, and unrecorded. Data were analyzed from July 1, 2021, to January 17, 2022. Exposure RYGB or SG. Outcomes Percentage total weight loss (%TWL); type 2 diabetes remission, relapse, and change in hemoglobin A1c (HbA1c) level; and postsurgical safety and utilization outcomes (operations, interventions, revisions/conversions, endoscopy, hospitalizations, mortality, 30-day major adverse events) at 1, 3, and 5 years after surgery. Results A total of 36 871 patients (mean [SE] age, 45.0 [11.7] years; 29 746 female patients [81%]) were included in the weight analysis. Patients identified with the following race and ethnic categories: 6891 Black (19%), 8756 Hispanic (24%), 19 645 White (53%), 826 other (2%), and 783 unrecorded (2%). Weight loss and mean reductions in HbA1c level were larger for RYGB than SG in all years for Black, Hispanic, and White patients (difference in 5-year weight loss: Black, -7.6%; 95% CI, -8.0 to -7.1; P < .001; Hispanic, -6.2%; 95% CI, -6.6 to -5.9; P < .001; White, -5.9%; 95% CI, -6.3 to -5.7; P < .001; difference in change in year 5 HbA1c level: Black, -0.29; 95% CI, -0.51 to -0.08; P = .009; Hispanic, -0.45; 95% CI, -0.61 to -0.29; P < .001; and White, -0.25; 95% CI, -0.40 to -0.11; P = .001.) The magnitude of these differences was small among racial and ethnic groups (1%-3% of %TWL). Black and Hispanic patients had higher risk of hospitalization when they had RYGB compared with SG (hazard ratio [HR], 1.45; 95% CI, 1.17-1.79; P = .001 and 1.48; 95% CI, 1.22-1.79; P < .001, respectively). Hispanic patients had greater risk of all-cause mortality (HR, 2.41; 95% CI, 1.24-4.70; P = .01) and higher odds of a 30-day major adverse event (odds ratio, 1.92; 95% CI, 1.38-2.68; P < .001) for RYGB compared with SG. There was no interaction between race and ethnicity and operation type for diabetes remission and relapse. Conclusions and Relevance Variability of the comparative effectiveness of operations for %TWL and HbA1c level across race and ethnicity was clinically small; however, differences in safety and utilization outcomes were clinically and statistically significant for Black and Hispanic patients who had RYGB compared with SG. These findings can inform shared decision-making regarding bariatric operation choice for different racial and ethnic groups of patients.

Abstract
PURPOSE The Bariatric Experience Long Term (BELONG) prospective study cohort was created to address limitations in the literature regarding the relationship between surgical weight loss and psychosocial, health, behaviour and environmental factors. The BELONG cohort is unique because it contains 70% gastric sleeve and 64% patients with non-white race/ethnicity and was developed with strong stakeholder engagement including patients and providers. PARTICIPANTS The BELONG cohort study included 1975 patients preparing to have bariatric surgery who completed a baseline survey in a large integrated health system in Southern California. Patients were primarily women (84%), either black or Hispanic (59%), with a body mass index (BMI) of 45.1±7.4 kg/m2, age 43.3±11.5 years old, and 32% had at least one comorbidity. FINDINGS TO DATE A total of 5552 patients were approached before surgery between February 2016 and May 2017, and 1975 (42%) completed a baseline survey. A total of 1203 (73%) patients completed the year 1 and 1033 (74%) patients completed the year 3 postoperative survey. Of these survey respondents, 1341 at baseline, 999 at year 1, and 951 at year 3 were included in the analyses of all survey and weight outcome data. A total of 803 (60% of eligible patients) had survey data for all time points. Data collected were self-reported constructs to support the proposed theoretical model. Height, weight and BMI were abstracted from the electronic medical record to obtain the main outcomes of the study: weight loss and regain. FUTURE PLANS We will collect self-reported constructs and obtain height, weight and BMI from the electronic medical record 5 years after bariatric surgery between April 2022 and January 2023. We will also collect patient experiences using focus groups of 8-12 patients each throughout 2022.

Abstract
BACKGROUND Of complications after bariatric surgery, venous thromboembolism (VTE) has the greatest impact on mortality. OBJECTIVES To examine risk factors for postoperative VTE and identify high-risk patients who may benefit from prolonged prophylaxis. SETTING National Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database METHODS: Patients who underwent primary, laparoscopic bariatric surgery 2015-2019 were identified. Risk factors were sex, age, body mass index (BMI), history of VTE, immobility, venous stasis disease, operative time greater >3 hours, and procedure type. Multivariable logistic regression was used to examine associations between factors and the outcome of postoperative VTE. We examined contributions of each factor through average marginal effects and E-values. We added Black versus White race to the same regression model to understand whether race acted as a moderating factor. RESULTS In our study, 1677 of 605,782 (.28%) patients experienced postoperative VTE. On multivariable analysis, previous history of VTE had the greatest association, increasing risk of postoperative VTE by +.90% points (95% CI [confidence interval] +.73% to +1.07%). Lower-95% CI E-value bounds were 1.43 for men, 1.11 preoperative BMI, 7.38 history of VTE, and 2.15 operative length >3 hours. Black patients had an additional +.18% (95% CI +.14 to +.22%) risk of postoperative VTE, corresponding to a lower E-value bound of 2.50. CONCLUSION In this study using recent years' national bariatric surgery data, we find history of VTE is the greatest driver of postoperative VTE. Most importantly, Black patients are more likely to suffer postoperative VTE. Now is the time to use the power of quality improvement programs to ensure health equity for all our patients.

Abstract
Background Few bariatric surgery programs exist at safety net hospitals which often serve patients of diverse racial and socioeconomic backgrounds. A bariatric surgery program was developed at a large urban safety net medical center serving a primarily Hispanic population. The purpose of this study was to evaluate safety, feasibility, and first-year outcomes to pave the way for other safety net bariatric programs. Methods The bariatric surgery program was started at a safety net hospital located in a neighborhood with over twice the national poverty rate. A retrospective review was performed for patient demographics, comorbidities, preoperative diet and exercise habits, perioperative outcomes, and 1-year outcomes including percent total weight lost (%TWL) and comorbidity reduction. Results A total of 153 patients underwent laparoscopic sleeve gastrectomy from May 2017 through December 2019. The average preoperative BMI was 47.9kg/m2, and 54% of patients had diabetes. The 1-year follow-up rate was 94%. There were no mortalities and low complication rates. The average 1-year %TWL was 22.8%. Hypertension and diabetes medications decreased in 52% and 55% of patients, respectively. The proportion of diabetic patients with postoperative HbA1c <6.0% was 49%. Conclusion This is one of the first reports on the outcomes of a bariatric surgery program at a safety net hospital. This analysis demonstrates feasibility and safety, with no mortalities, low complication rates, and acceptable %TWL and comorbidity improvement. More work is needed to investigate the impacts of race, culture, and socioeconomic factors on bariatric outcomes in this population. Graphical abstract ![]()

Abstract
IMPORTANCE Bariatric surgical weight loss is associated with reduced cardiovascular mortality; however, the mechanisms underlying this association are incompletely understood. OBJECTIVES To identify variables associated with vascular remodeling after bariatric surgery and to examine how sex, race, and metabolic status are associated with microvascular and macrovascular outcomes. DESIGN, SETTING, AND PARTICIPANTS This population-based longitudinal cohort included 307 individuals who underwent bariatric surgery. Participants were enrolled in the bariatric weight loss program at Boston Medical Center, a large, multi-ethnic urban hospital, with presurgical and postsurgical assessments. Data were collected from December 11, 2001 to August 27, 2019. Data were analyzed in September 2019. EXPOSURE Bariatric surgery. MAIN OUTCOMES AND MEASURES Flow-mediated dilation (FMD) and reactive hyperemia (RH) (as measures of macrovascular and microvascular function, respectively) and clinical variables were measured preoperatively at baseline and at least once postoperatively within 12 months of the bariatric intervention. RESULTS A total of 307 participants with obesity (mean [SD] age, 42 [12] years; 246 [80%] women; 199 [65%] White; mean [SD] body mass index, 46 [8]) were enrolled in this study. Bariatric surgery was associated with significant weight loss and improved macrovascular and microvascular function across subgroups of sex, race, and traditional metabolic syndrome (mean [SD] pre- vs postsurgery weight: 126 [25] kg vs 104 [25] kg; P < .001; mean [SD] pre- vs postsurgery FMD: 9.1% [5.3] vs 10.2% [5.1]; P < .001; mean [SD] pre- vs postsurgery RH: 764% [400] vs 923% [412]; P < .001). Factors associated with change in vascular phenotype correlated most strongly with adiposity markers and several metabolic variables depending on vascular territory (eg, association of weight change with change in RH: estimate, -3.2; 95% CI, -4.7 to -1.8; association of hemoglobin A1c with change in FMD: estimate, -0.5; 95% CI, -0.95 to -0.05). While changes in macrovascular function among individuals with metabolically healthy obesity were not observed, the addition of biomarker assessment using high-sensitivity C-reactive protein plasma levels greater than 2 mg/dL identified participants with seemingly metabolically healthy obesity who had low-grade inflammation and achieved microvascular benefit from weight loss surgery. CONCLUSIONS AND RELEVANCE The findings of this study suggest that bariatric intervention is associated with weight loss and favorable remodeling of the vasculature among a wide range of individuals with cardiovascular risk. Moreover, differences in arterial responses to weight loss surgery by metabolic status were identified, underscoring heterogeneity in physiological responses to adiposity change and potential activation of distinct pathological pathways in clinical subgroups. As such, individuals with metabolically healthy obesity represent a mixed population that may benefit from more refined phenotypic classification.

Abstract
Simple Summary Metabolic (bariatric) surgery (MBS) provides the greatest maximum and sustained weight loss among individuals who are morbidly obese. It is more effective than lifestyle interventions in improving or eliminating type 2 diabetes mellitus (T2DM) and in decreasing cardiovascular (CV) risk. Preclinical studies have been conducted to investigate the mechanisms by which MBS leads to the benefits in T2DM and CV risk. In this review, we describe the emerging evidence that MBS may also impact cancer risk and mortality, and whom may benefit most. We describe the long term involvement and commitment of the National Institutes of Health in obesity research in general and MBS in particular. We outline the need for additional research to understand the mechanism(s) by which MBS may influence cancer, since these mechanism(s) are currently unknown. Abstract Metabolic (bariatric) surgery (MBS) is recommended for individuals with a BMI > 40 kg/m2 or those with a BMI 35–40 kg/m2 who have one or more obesity related comorbidities. MBS leads to greater initial and sustained weight loss than nonsurgical weight loss approaches. MBS provides dramatic improvement in metabolic function, associated with a reduction in type 2 diabetes mellitus and cardiovascular risk. While the number of MBS procedures performed in the U.S. and worldwide continues to increase, they are still only performed on one percent of the affected population. MBS also appears to reduce the risk of certain obesity related cancers, although which cancers are favorably impacted vary by study, who benefits most is uncertain, and the mechanism(s) driving this risk reduction are mostly speculative. The goal of this manuscript is to highlight (1) emerging evidence that MBS influences cancer risk, and that the potential benefit appears to vary based on cancer, gender, surgical procedure, and likely other variables; (2) the role of the NIH in MBS research in T2DM and CV risk for many years, and more recently in cancer; and (3) the opportunity for research to understand the mechanism(s) by which MBS influences cancer. There is evidence that women benefit more from MBS than men, that MBS may actually increase the risk of colorectal cancer in both women and men, and there is speculation that the benefit in cancer risk reduction may vary according to which MBS procedure an individual undergoes. Herein, we review what is currently known, the historical role of government, especially the National Institutes of Health (NIH), in driving this research, and provide suggestions that we believe could lead to a better understanding of whether and how MBS impacts cancer risk, which cancers are impacted either favorably or unfavorably, the role of the NIH and other research agencies, and key questions to address that will help us to move the science forward.

Abstract
Background Racial disparities in postoperative complications have been demonstrated in bariatric surgery, yet the relationship of race to complication severity is unknown. Study Design Adult laparoscopic primary bariatric procedures were queried from the 2015 and 2016 MBSAQIP registry. Adjusted logistic and multinomial regressions were used to examine the relationships between race and 30-day complications categorized by the Clavien-Dindo grading system. Results A total of 212,970 patients were included in the regression analyses. For Black patients, readmissions were higher (OR = 1.39, p < 0.0001) and the odds of a Grade 1, 3, 4, or 5 complication were increased compared with White patients (OR = 1.21, p < 0.0001; OR = 1.21, p < 0.0001; OR = 1.22, p = 0.01; and OR = 1.43, p = 0.04) respectively. The odds of a Grade 3 complication for Hispanic patients were higher compared with White patients (OR = 1.59, p < 0.0001). Conclusion Black patients have higher odds of readmission and multiple grades of complications (including death) compared with White patients. Hispanic patients have higher odds of a Grade 3 complication compared with White patients. No significant differences were found with other races. Specific causes of these disparities are beyond the limitations of the dataset and stand as a topic for future inquiry.

Abstract
Weight reduction continues to be first-line therapy in the treatment of hypertension (HTN). However, the long-term effect of bariatric malabsorptive surgical techniques such as Roux-en-Y Gastric Bypass (RYGB) surgery in the management of hypertension (HTN) is less clear. African Americans (AA) are disproportionately affected by obesity and hypertension and have inconsistent outcomes after bariatric surgery (BS). Despite a plethora of bariatric literature, data about characteristics of a predominantly AA bariatric hypertensive cohort including hypertension in obese (HIO) are scarce and underreported. The aims of this study were, (1) to describe the preoperative clinical characteristics of HIO with respect to HTN status and age, and (2) to identify predictors of HTN resolution one year after RYGB surgery in an AA bariatric cohort enrolled at the Howard University Center for Wellness and Weight Loss Surgery (HUCWWS). In the review of 169 AA bariatric patients, the average BMI was 48.50 kg/m2 and the average age was 43.86 years. Obese hypertensive patients were older (46 years vs. 37.89 years; p < .0001); had higher prevalence of diabetes mellitus (DM, 43.09% vs. 10.87%; p < .0001) and dyslipidemia (38.2% vs. 13.04%; p 0.002). Hypertensive AA who were taking ≥ 2 antihypertensive medications prior to RYGB were 18 times less likely to experience HTN resolution compared to hypertensive AA taking 0-1 medications, who showed full or partial response. Also, HIO was less likely to resolve after RYGB surgery in patients who needed ≥ 2 antihypertensive medications prior to surgical intervention.

Abstract
CONTEXT Weight regain (WR) after bariatric surgery is emerging as a common clinical problem due to the increase in the number of procedures performed. Early interventions are necessary to curtail the potential recurrence of comorbid conditions. However, it is often difficult to recognize WR early enough to introduce mitigating measures because there are no current guidelines for timely diagnosis and assessment of the severity of this condition. OBJECTIVE We present a practical approach for the early recognition of WR, based on 11-year follow-up data from our multiethnic bariatric surgery patient population. METHODS We classify WR according to the rate of increase in weight relative to nadir weight, normalized per 30-day interval. We also review pertinent literature about the etiologic factors contributing to WR after bariatric surgery. RESULTS According to our algorithm, mild, moderate, and rapid WR are defined as weight increases of 0.2% to <0.5%, 0.5% to 1.0%, and more than 1.0% of nadir weight per 30 days, respectively. Treatment options, including dietary counseling, use of antiobesity medication, and consideration of surgical revision, are described. A case is presented to illustrate the utility of timely identification of WR and the importance of collaboration between bariatric surgeons, obesity medicine specialists, and dietitians. CONCLUSION Our approach emphasizes the importance of regular long-term follow-up for all bariatric surgery patients.

Differential Metabolomic Signatures in Patients with Weight Regain and Sustained Weight Loss After Gastric Bypass Surgery: A Pilot Study. Dig Dis Sci 2020; 65:1144-1154. [PMID: 31385097 PMCID: PMC7340108 DOI: 10.1007/s10620-019-05714-3] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/11/2018] [Accepted: 07/02/2019] [Indexed: 12/13/2022]
Abstract
BACKGROUND While Roux-en-Y gastric bypass (RYGB) is one of the most effective and durable treatment options for obesity and its comorbidities, it is complicated by long-term weight regain in over 20% of patients. AIMS We sought to determine the metabolite signatures of serum samples of patients with weight regain (RYGB-WR) after RYGB and features distinguishing these patients from patients with sustained weight loss (RYGB-SWL). METHODS We prospectively analyzed serum samples from 21 RYGB-WR patients, 14 RYGB-SWL patients, and 11 unoperated controls. The main outcome measure was their serum metabolite profile. RESULTS Weight regain after RYGB was associated with a unique serum metabolomic fingerprint. Most of the statistically different metabolites were involved in amino acid metabolism, one-carbon metabolism, and related nucleotide metabolism. A principal component analysis identified groups of metabolites that correlate with weight regain. Specifically, weight regain was associated with lower serum levels of metabolites related to the serine, glycine and threonine pathway, phenylalanine metabolism, tricyclic acid cycle, alanine and glutamate metabolism, and higher levels of other amino acids. CONCLUSIONS Weight regain after RYGB is associated with unique serum metabolite signatures. Metabolite profiling may eventually help us to identify markers that could differentiate the patients who will regain weight versus those who will likely sustain weight loss.

Abstract
Importance The outcomes of bariatric surgery vary considerably across patients, but the association of race with these measures remains unclear. Objective To examine the association of race on perioperative and 1-year outcomes of bariatric surgery. Design, Setting, and Participants Propensity score matching was used to assemble cohorts of black and white patients from the Michigan Bariatric Surgery Collaborative who underwent a primary bariatric operation (Roux-en-Y gastric bypass, sleeve gastrectomy, or adjustable gastric banding) between June 2006 and January 2017. Cohorts were balanced on baseline characteristics and procedure. Conditional fixed-effects models were used to evaluate the association of race on outcomes within hospitals and surgeons. Data analysis occurred from June 2006 through August 2018. Main Outcomes and Measures Thirty-day complications and health care resource utilization measures, as well as 1-year weight loss, comorbidity remission, quality of life, and satisfaction. Results In each group, 7105 patients were included. Black patients had a higher rate of any complication (628 [8.8%] vs 481 [6.8%]; adjusted odds ratio, 1.33 [95% CI, 1.17-1.51]; P = .02), but there were no significant differences in the rates of serious complications (178 [2.5%] vs 135 [1.9%]; adjusted odds ratio, 1.32 [95% CI, 1.05-1.66]; P = .29) or mortality (5 [0.10%] vs 7 [0.10%]; adjusted odds ratio, 0.73 [95% CI, 0.23-2.31]; P = .54). Black patients had a greater length of stay (mean [SD], 2.2 [3.0] days vs 1.9 [1.7] days; adjusted odds ratio, 0.30 [95% CI, 0.20-0.40]; P < .001), as well as a higher rate of emergency department visits (541 [11.6%] vs 826 [7.6%]; adjusted odds ratio, 1.60 [95% CI, 1.43-1.79]; P < .001) and readmissions (414 [5.8%] vs 245 [3.5%]; adjusted odds ratio, 1.73 [95% CI, 1.47-2.03]; P < .001). At 1 year, black patients had lower mean total body weight loss and as a percentage of weight (32.0 kg [26%]; vs 38.3 kg [29%]; P < .001) and this held true across procedures. Remission of hypertension was lower for black patients (564 [40.0%] vs 1096 [56.0%]; P < .001), but the rate of sleep apnea remission (467 [62.6%] vs 615 [56.1%]; P = .005) and gastroesophageal reflux disease (309 [78.6%] vs 453 [75.4%]; P = .049) were higher. There were no significant differences in remission of diabetes with insulin dependence, diabetes without insulin dependence,or hyperlipidemia hyperlipidemia. Fewer black patients than white patients reported a good or very good quality of life (1379 [87.2%] vs 2133 [90.4%]; P = .002) and being very satisfied with surgery (1908 [78.4%] vs 2895 [84.2%]; P < .001) at 1 year. Conclusions and Relevance Black patients undergoing bariatric surgery in Michigan had significantly higher rates of 30-day complications and resource utilization and experienced lower weight loss at 1 year than a matched cohort of white patients. While sleep apnea and gastroesophageal reflux disease remission were higher and hypertension remission lower in black patients, comorbidity remission was otherwise similar between matched cohorts. Racial and cultural differences among patients should be considered when designing strategies to optimize outcomes with bariatric surgery.

Abstract
OBJECTIVE Weight recidivism following Roux-en-Y gastric bypass (RYGB) is common and is associated with recurrence of comorbidities. Studies with long-term follow-up of recidivism quantified by weight regain (WR) are lacking. A retrospective review of all RYGB at our center from 2004 to 2015 was performed to examine the effects of race and type 2 diabetes on WR following RYGB. METHODS Multivariable linear mixed models were used for the effects of time and race on weight, WR relative to nadir weight (WR/nadir), and WR relative to maximal weight loss, and Cox regressions were used for low, moderate, and high WR/nadir. RESULTS A total of 1,395 participants were identified. The sample was limited to African American (AA), Caucasian American (CA), and Hispanic American (HA) participants. The effects of time (P < 0.0001), race (P < 0.0001), and race × time interaction (P = 0.0008) on weight trajectory were significant. AA had significantly more WR than CA (P < 0.01). AA and HA had a higher hazard ratio for having low, moderate, and rapid WR/nadir. CONCLUSIONS Racial disparities after RYGB include WR and particularly affect AA. Understanding the etiologic factors that contribute to these disparities is important to optimize the long-term clinical outcomes of bariatric surgery.

Abstract
BACKGROUND NonHispanic black patients bear a disproportionate burden of the obesity epidemic and its related medical co-morbidities. While bariatric surgery is the most effective treatment for morbid obesity, black patients access bariatric surgery at lower rates than nonHispanic white patients. OBJECTIVES To examine racial differences before bariatric surgery and in short-term perioperative outcomes and complications, and the extent to which race is independently associated with perioperative morbidity and mortality. SETTING Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program national database. METHODS Data were extracted from the 2015 Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program Participant Use File. Multivariate analysis was used to identify differences in mortality, length of stay, readmission, and reintervention by race in patients undergoing laparoscopic Roux-en-Y gastric bypass or laparoscopic sleeve gastrectomy (SG). RESULTS A total of 108,198 patients were included in the analysis. There were significant differences in perioperative disease burden. Black patients had a higher body mass index at the time they underwent surgery (laparoscopic Roux-en-Y gastric bypass: 48.0 versus 45.7 kg/m2; SG: 46.8 versus 44.9 kg/m2; P < .001). Black patients had significantly longer length of stay and higher rates of readmission in both the laparoscopic Roux-en-Y gastric bypass and SG groups. In the SG group, black patients had significantly higher 30-day mortality (.2% versus .1%, odds ratio = 3.613, 95% confidence interval 1.990-6.558, P < .001) and higher rates of reoperation or reintervention. CONCLUSIONS We found significant racial disparities in bariatric surgery outcomes, including higher mortality in black patients undergoing SG. The specific causes of these disparities remain unclear and must be the subject of future research.

Abstract
PURPOSE OF REVIEW Obesity rates in the USA have reached pandemic levels with one third of the population with obesity in 2015-2016 (39.8% of adults and 18.5% of youth). It is a major public health concern, and it is prudent to understand the factors which contribute. Racial and ethnic disparities are pronounced in both the prevalence and treatment of obesity and must be addressed in the efforts to combat obesity. RECENT FINDINGS Disparities in prevalence of obesity in racial/ethnic minorities are apparent as early as the preschool years and factors including genetics, diet, physical activity, psychological factors, stress, income, and discrimination, among others, must be taken into consideration. A multidisciplinary team optimizes lifestyle and behavioral interventions, pharmacologic therapy, and access to bariatric surgery to develop the most beneficial and equitable treatment plans. The reviewed studies outline disparities that exist and the impact that race/ethnicity have on disease prevalence and treatment response. Higher prevalence and reduced treatment response to lifestyle, behavior, pharmacotherapy, and surgery, are observed in racial and ethnic minorities. Increased research, diagnosis, and access to treatment in the pediatric and adult populations of racial and ethnic minorities are proposed to combat the burgeoning obesity epidemic and to prevent increasing disparity.

Abstract
PURPOSE OF REVIEW Numerous lines of evidence support the likelihood that inflammation drives the transition from obese/metabolically healthy to obese/type 2 diabetes (T2D). Given the temporal flexibility of inflammation in obesity-associated T2D, investigators have hypothesized that a precipitous drop in diabetogenic cytokines is critical for rapid 'T2D remission' following surgery but prior to significant weight loss. We review the evidence that changes in diabetogenic cytokines play a role in outcomes of bariatric surgery, including improved glycemic control. RECENT FINDINGS A 2016 indication for bariatric surgery to treat T2D integrates the large body of data showing rapid metabolic improvement. Parameters that account for improved glycemic control prior to significant weight loss, T2D recidivism over the long term, or failure of surgery to remit T2D in some patients are incompletely understood. SUMMARY We review the evidence that changes in diabetogenic cytokines play a role in outcomes of bariatric surgery, including improved glycemic control. We brainstorm future research directions that may improve surgical results.
