Effects of bariatric surgery on sexual function and fertility: A narrative review. Obes Rev 2024:e13757. [PMID: 38689132 DOI: 10.1111/obr.13757] [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: 04/26/2023] [Revised: 04/04/2024] [Accepted: 04/05/2024] [Indexed: 05/02/2024]
Abstract
Obesity has emerged as a prevalent global health concern, with its detrimental effects on the reproductive system and sexual function garnering increasing attention. Both men and women affected by obesity face a heightened risk of fertility challenges and sexual dysfunction. Although fertility and sexual function are distinct topics, they are intricately linked and mutually influential in both medical and societal contexts. Bariatric surgery (BS) has generated promising results in alleviating sexual dysfunction and enhancing fertility, results which are often gender specific. In men, improvements in sexual function can often be attributed to weight loss and subsequent optimizations in sex hormone levels. However, improving female sexual function may be related to a range of factors beyond weight loss. Bariatric procedures have shown limited benefits for male fertility; in fact, in some situations it can even be detrimental, leading to a decrease in sperm count and quality. Conversely, BS may positively impact female fertility, improving pregnancy and neonatal outcomes. Nevertheless, it is essential to consider the potential risks related to the adverse effects of malnutrition and rapid weight loss following BS, making it advisable to wait for 12-18 months before attempting pregnancy.

Preoperative depression and outcomes after metabolic and bariatric surgery: A systematic narrative review. Obes Rev 2024:e13743. [PMID: 38572605 DOI: 10.1111/obr.13743] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/12/2023] [Revised: 02/08/2024] [Accepted: 03/10/2024] [Indexed: 04/05/2024]
Abstract
Preoperative depression is prevalent among patients undergoing metabolic and bariatric surgery (MBS) and is a potentially modifiable risk factor. However, the impact of preoperative depression on MBS outcomes has not been systematically reviewed. A search of MEDLINE, Embase, Cochrane, and PsychINFO (inception to June 2023) was conducted for studies reporting associations between preoperative depression and any clinical or patient-reported outcomes after MBS. Eighteen studies (5 prospective and 13 retrospective) reporting on 5933 participants were included. Most participants underwent gastric bypass or sleeve gastrectomy. Meta-analyses were not conducted due to heterogeneity in reported outcomes; findings were instead synthesized using a narrative and tabular approach. Across 13 studies (n = 3390) the associations between preoperative depression and weight loss outcomes at 6-72 months were mixed overall. This may be related to differences in cohort characteristics, outcome definitions, and instruments used to measure depression. A small number of studies reported that preoperative depression was associated with lower quality of life, worse acute pain, and more perioperative complications after surgery. Most of the included studies were deemed to be at high risk of bias, resulting in low or very low certainty of evidence according to the Risk of Bias In Non-randomized Studies - of Exposure (ROBINS-E) tool. While the impact of preoperative depression on weight loss after MBS remains unclear, there is early evidence that depression has negative consequences on other patient-important outcomes. Adequately powered studies using more sophisticated statistical methods are needed to accurately estimate these associations.

Impact of antidepressant use on post-operative weight loss following bariatric surgery. Ir J Med Sci 2024; 193:903-908. [PMID: 37728725 DOI: 10.1007/s11845-023-03482-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2023] [Accepted: 07/26/2023] [Indexed: 09/21/2023]
Abstract
BACKGROUND Antidepressant medication can be associated with weight gain. Consideration should be given to the specific agent prescribed to optimize bariatric surgery outcomes. AIM The aim of this study is to investigate if patients treated with antidepressants stratified by risk of weight gain are associated with less weight loss at 1 year postbariatric surgery. METHOD A single centre, retrospective analysis of all patients who underwent bariatric surgery between July 2018 and 2021 within St Vincent's University Hospital group. The exposure was antidepressant use, stratified for risk of weight gain, and the control group was patients who underwent surgery but no antidepressant use. The primary outcome was % TWL (total weight loss) at 6 weeks, 6 months and 12 months post-surgery. Multivariate linear regression analysis was used to estimate the impact of antidepressant treatment on post-surgery weight loss at 12 months using the variables of age, gender and pre-operative BMI. RESULTS Of the total cohort (n = 315), 70 patients (22.2%) were taking antidepressants. At 12 months, post-operatively patients taking medium risk for weight gain antidepressants had significantly less mean %TWL compared to those not taking antidepressants (p = 0.015). Overall, taking any antidepressant was not found to be a significant predictor of %TWL at 12 months after surgery (β = - 2.590, p = 0.0836). CONCLUSION Many patients undergoing bariatric surgery have concurrent psychiatric conditions. Given the complex relationship between bariatric surgery and mental health, psychotropic medications may be best managed by a specialist in the field such as a bariatric psychiatrist in order to optimize patient outcomes.

Six-year postoperative associations between the Minnesota Multiphasic Personality Inventory - 3 (MMPI-3) and weight recurrence, eating behaviors, adherence, alcohol misuse, and quality of life. Surg Obes Relat Dis 2024; 20:391-398. [PMID: 38216363 DOI: 10.1016/j.soard.2023.12.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2023] [Revised: 11/20/2023] [Accepted: 12/06/2023] [Indexed: 01/14/2024]
Abstract
BACKGROUND Metabolic and bariatric surgery (MBS) leads to beneficial and sustained outcomes. However, many patients evidence weight recurrence and psychosocial functioning may be associated with weight recurrence. The Minnesota Multiphasic Personality Inventory - 3 (MMPI-3) is validated for use in presurgical MBS evaluations and likely has clinical utility in understanding weight recurrence and other aspects of postoperative functioning. OBJECTIVE The objective of the current investigation is to understand how postoperative psychosocial functioning relates to weight recurrence and other behaviors and constructs 6 years after MBS. SETTING Cleveland Clinic Bariatric and Metabolic Institute. METHODS A sample of 163 participants consented to take a battery of self-report measures related to psychological functioning, eating behaviors, adherence, alcohol misuse, and quality of life along with their postoperative weight. MMPI-3 scale scores were prorated from the Minnesota Multiphasic Personality Inventory - 2 - Restructured Form (MMPI-2-RF) or scored from the Minnesota Multiphasic Personality Inventory - 2 - Restructured Form - Expanded (MMPI-2-RF-EX). RESULTS Weight recurrence was quite variable in this sample. Postoperative MMPI-3 scales related to emotional/internalizing dysfunction were modestly associated with higher weight recurrence. Postoperative MMPI-3 scale scores also demonstrated associations with other postoperative outcomes including measures of eating behaviors, adherence, alcohol misuse, and quality of life. CONCLUSIONS Postoperative psychosocial functioning as assessed by the MMPI-3 was associated with weight recurrence and a number of other problematic psychological outcomes beyond weight recurrence.

Association between obesity and female sexual dysfunction: a review. Sex Med Rev 2024; 12:154-163. [PMID: 38112599 DOI: 10.1093/sxmrev/qead047] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2023] [Revised: 10/20/2023] [Accepted: 10/26/2023] [Indexed: 12/21/2023]
Abstract
INTRODUCTION Obesity is a global health crisis that has been growing over the past few decades. The economic burden associated with obesity is substantial as it is associated with multiple disabling chronic diseases, such as cardiovascular disease, certain cancers, osteoarthritis, chronic pain, and mental illness. Obesity is known to be a risk factor for sexual dysfunction in men, but this association is less well understood in women. AIMS To provide a narrative review of the available literature on the relationship between overweight/obesity and female sexual dysfunction, elaborate on the possible mechanisms explaining this association, and discuss the effects of weight loss on sexual function in those with obesity. METHODS A search of the medical literature was carried out in PubMed and Medline, focusing on original research and systematic reviews of original research on obesity and sexual function in women. RESULTS The relationship between obesity and female sexual function is not consistent across studies. While women with obesity are more likely to have worse sexual function and avoid sexual activity, many studies have failed to identify these associations. Lifestyle changes resulting in weight loss lead to better sexual function, and bariatric surgery has been shown to improve sexual function in the first couple of years following the procedure; yet, the long-term effects of weight loss and bariatric surgery are still uncertain. CONCLUSIONS The evidence on the relationship between obesity and female sexual function is mixed. Nevertheless, weight loss has been shown to improve sexual function in women with obesity. The impact of weight loss medications and the long-term effect of bariatric surgery on female sexual function require further study.

Abstract
Background Bariatric surgery (BS) is an effective therapy for those who are excessively obese. However, the consequences of surgery on mental health are still debatable. We aimed to investigate the patients' depression, stress, and anxiety levels before and after BS at two different times: just before surgery and 12 months later. Methods This is a repeated cross-sectional study. The Depression Anxiety Stress Scale (DASS-21) was used to assess depression, anxiety, and stress levels. Results There were 288 participants in the BS groups. Changes in anxiety, stress, and depressive symptoms over time were examined using generalised estimating equations models with repeated measurements per individual. Anxiety (incidence rate ratio [IRR] = 1.2, p < .001) and stress (IRR = 0.86, p < .001) worsened, whereas depression (IRR = -1.8, p < .001) improved significantly in 288 patients one year after BS. Conclusions BS had significant impacts on obesity-associated mental health issues.

Abstract
PURPOSE Sleeve gastrectomy (SG), the most commonly performed weight loss surgery in adolescents and young adults with moderate to severe obesity, is highly effective for weight loss. Current literature regarding depressive and anxiety symptomatology following SG in youth is sparse and conflicting. We evaluated changes in depressive and anxiety symptoms in adolescents and young adults with moderate to severe obesity 2 years following SG compared with non-surgical controls (NS) followed for a similar duration. MATERIALS AND METHODS Forty-six youth 13-25 years old with moderate-severe obesity (33 female) were followed for 2 years; 21 underwent SG, and 25 were NS. Subjects underwent anthropometric measurements and completed self-report questionnaires. Beck Depression Inventory-II (BDI-II) was used to assess depressive symptoms and the State-Trait Anxiety Inventory (STAI)-X2 for anxiety symptoms. RESULTS Groups did not differ for age (18.4 ± 0.4 vs. 17.8 ± 0.5 years, p = 0.456). The SG group had a higher mean BMI vs. NS (47.5 (42.1, 52.4) vs. 41.6 (37.8, 46.5) kg/m2; p = 0.011). At 2-year follow-up, SG had greater reductions in weight and BMI vs. NS (p < 0.0001). Groups did not differ for changes in BDI-II and STAI scores (BDI-II: - 1.0 (- 6.0, 10.0) in SG vs. - 1.0 (- 6.0, 3.5) in NS, p = 0.37; STAI: 3.1 ± 3.2 in SG vs. - 1.1 ± 1.5 in NS, p = 0.24). CONCLUSION No change was found in depressive and anxiety symptomatology following surgery despite marked weight reduction over a 2-year period, underscoring the need to better evaluate psychopathology in youth undergoing SG to develop supportive therapeutic strategies.

Abstract
There have been numerous investigations of aberrant eating and substance abuse among patients who have undergone bariatric surgery, which affects the metabolism and the pharmacokinetics of alcohol. However, there is a dearth of literature considering the complex interplay between changes in post-surgery food and alcohol consumption. Furthermore, despite the increasing recognition of issues surrounding replacing food consumption with alcohol consumption (Food and Alcohol Disturbance [FAD]), most emerging research has focused on young adult populations. This perspective reviews and synthesizes the small but growing body of research on the interplay between food and alcohol consumption, particularly FAD, and considers its application to bariatric surgery in general. There are unique considerations for patients who have undergone bariatric surgery. Patients experience altered gastric anatomy, which affects food and alcohol metabolism, and are advised to abstain from drinking alcohol after surgery. After reviewing the available literature, this perspective highlights future directions for research and practice in bariatric surgery.

Prevalence and short-term change in symptoms of anxiety and depression following bariatric surgery: a prospective cohort study. BMJ Open 2024; 14:e071231. [PMID: 38171620 PMCID: PMC10773381 DOI: 10.1136/bmjopen-2022-071231] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/24/2022] [Accepted: 11/23/2023] [Indexed: 01/05/2024] Open
Abstract
OBJECTIVES Bariatric surgery is an effective treatment for severe obesity that leads to significant physical health improvements. Few studies have prospectively described the short-term impact of surgery on mental health using standardised case-finding measures for anxiety or depressive disorders. This study describes the prevalence and short-term course of these conditions following surgery. DESIGN Prospective observational cohort study. SETTING 12 National Health Service centres in England. PARTICIPANTS Participants studied took part in the By-Band-Sleeve study, a multicentre randomised controlled trial evaluating the surgical management of severe obesity. We included participants who had undergone surgery (gastric bypass, gastric band or sleeve gastrectomy) within 6 months of randomisation. PRIMARY AND SECONDARY OUTCOME MEASURES Anxiety and depression were assessed using the Hospital Anxiety and Depression Scale (HADS) at baseline and 12 months post-randomisation. Sociodemographic variables collected at prerandomisation included body mass index, age, sex, ethnicity, marital status, tobacco use, employment status and income band. RESULTS In our sample of 758 participants, 94.5% (n 716) and 93.9% (n 712) had completed baseline anxiety (HADS-A) and depression (HADS-D) subscales. At pre-randomisation 46.1% (n 330/716, 95% CI 42.4% to 49.7%) met clinical case criteria for anxiety and 48.2% (n 343/712, 95% CI 44.5% to 51.8%) for depression. Among participants returning completed 12 months post-randomisation questionnaires (HADS-A n 503/716, HADS-D n 498/712), there was a significant reduction in the proportion of clinical cases with anxiety (-9.5%, 95% CI -14.3% to -4.8% p<0.001) and depression (-22.3%, 95% CI -27.0% to -17.6% p<0.001). CONCLUSIONS Almost half of people undergoing bariatric surgery had underlying anxiety or depressive symptoms. In the short term, these symptoms appear to substantially improve. Future work must identify whether these effects are sustained beyond the first post-randomisation year. TRIAL REGISTRATION NUMBER NCT02841527 and ISRCTN00786323.

Suicide attempts after bariatric surgery: comparison to a nonsurgical cohort of individuals with severe obesity. Surg Obes Relat Dis 2023; 19:1458-1466. [PMID: 37758538 PMCID: PMC10843496 DOI: 10.1016/j.soard.2023.08.013] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2023] [Revised: 08/14/2023] [Accepted: 08/28/2023] [Indexed: 09/29/2023]
Abstract
BACKGROUND The rate of suicide is higher among individuals following bariatric surgery compared with the general population; however, it is not clear whether risk is associated with bariatric surgery beyond having severe obesity. OBJECTIVE To compare the risk of a suicide attempt among those who had bariatric surgery versus a nonsurgical cohort with severe obesity. SETTING Aggregate count data were collected from 5 healthcare systems. METHODS Individuals were identified in the surgical cohort if they underwent bariatric surgery between 2009 and 2017 (n = 35,522) and then were compared with a cohort of individuals with severe obesity who never had bariatric surgery (n = 691,752). Suicide attempts were identified after study enrollment date using International Classification of Diseases, Ninth and Tenth Editions (ICD-9 and ICD-10) diagnosis codes from 2009 to 2021. RESULTS The relative risk of a suicide attempt was 64% higher in the cohort with bariatric surgery than that of the nonsurgical cohort (2.2% versus 1.3%; relative risk = 1.64; 95% CI, 1.53-1.76). Within the cohort with bariatric surgery, suicide attempts were more common among the 18- to 39-year age group (P < .001), women (P = .002), Hawaiian-Pacific Islanders (P < .001), those with Medicaid insurance (P < .001), and those with a documented mental health condition at baseline (in the previous 2 years; P < .001). CONCLUSIONS The relative risk of suicide attempts was higher among those who underwent bariatric surgery compared with a nonsurgical cohort, though absolute risk remained low. Providers should be aware of this increased risk. Screening for suicide risk after bariatric surgery may be useful to identify high-risk individuals.

Abstract
INTRODUCTION Depression is strongly associated with obesity and is common among patients undergoing bariatric surgery. Little is known about the impact of depression on early postoperative outcomes or its association with substance use. METHODS The Michigan Bariatric Surgery Collaborative is a statewide quality improvement program that maintains a large clinical registry. We evaluated patients undergoing primary Roux-en-Y gastric bypass or sleeve gastrectomy between 2017 and 2022. Patients self-reported symptoms of depression (PHQ-8) and use of alcohol (AUDIT-C), smoking, prescription opiates, and marijuana at baseline. Preoperative PHQ-8 scores stratified patients based on severity: no depression (0-4), mild (5-9), moderate (10-14), or severe (15-24). We compared 30-day outcomes and substance use between patients with and without depression. RESULTS Among 44,301 patients, 30.8% had some level of depression, with 19.8% mild, 7.5% moderate, and 3.5% severe. Patients with depression were more likely to have an extended length of stay (LOS) (> 3 days) than those without depression (no depression 2.1% vs. severe depression 3.0%, p = 0.0452). There were no significant differences between no depression and severe depression groups in rates of complications (5.7% vs. 5.2%, p = 0.1564), reoperations (0.9%, vs. 0.8%, p = 0.7394), ED visits (7.7% vs. 7.8%, p = 0.5353), or readmissions (3.2% vs. 3.9%, p = 0.3034). Patients with severe depression had significantly higher rates of smoking (9.7% vs. 12.5%, p < 0.0001), alcohol use disorder (8.6% vs. 14.0%, p < 0.0001), opiate use (14.5% vs. 22.4%, p < 0.0001) and marijuana use (8.4%, vs. 15.5%, p = 0.0008). CONCLUSIONS This study demonstrated that nearly one-third of patients undergoing bariatric surgery have depression, with over 10% in the moderate to severe range. There was a significant association between preoperative depressive symptoms and extended LOS after bariatric surgery, as well as higher rates of smoking and use of marijuana, prescription opiates and alcohol. There was no significant effect on adverse events or other measures of healthcare utilization.

Abstract
Aims To evaluate the breadth, depth and effectiveness of the evidence quality of all existing studies on bariatric surgery and mental health outcomes. Design Umbrella review of existing Systematic review and meta-analyses. Data sources PubMed, Embase, Web of Science, and the Cochrane Liberally databases of Systematic review and meta-analyses, and hand searching the reference lists of eligible publications. Results The search identified nine studies and 20 mental health outcomes from 1251 studies. Evidence shows that bariatric surgery is associated with significant improvement in areas such as anxiety, depression and eating disorders (including binge-eating disorder), and there is a significant harmful association with suicide, self-harm and alcohol use disorder (AUD). Among them, the most studied outcome is depression (4 articles). High-quality evidence proves that the score of depressive symptoms can be significantly improved after bariatric surgery within a two-year follow-up period and is not affected by the follow-up time. Low-quality evidence shows that bariatric surgery can significantly reduce depressive symptoms regardless of age and BMI, with an odds ratio (OR) of 0.49. Regardless of the postoperative BMI, the anxiety symptoms of women over 40 still decreased significantly, with an OR of 0.58. Regardless of the type of surgery, surgery can significantly reduce the incidence of eating disorders and symptoms. However, there is no obvious change in the follow-up time of AUD in the first two years after bariatric surgery, and the risk increases obviously in the third year, with an OR of 1.825. The evidence of moderate research shows that the risk of suicide and self-harm increases after bariatric surgery. The odds ratios in the same population and the control group were 1.9 and 3.8 times, respectively. Conclusion Bariatric surgery is beneficial for improving most mental health-related outcomes. However, we should be cautious about the increased risk of adverse mental health after surgery, such as suicide, self-harm, and AUD.

Abstract
INTRODUCTION A therapeutic approach to severe obesity is bariatric surgery (BS), which is considered an effective intervention for ameliorating comorbidities such as T2DM, hypertension, dyslipidemia, and cardiovascular diseases. Some polymorphisms are considered markers for addictive disorders and hedonic hunger. We analyzed factors associated with the outcomes of BS, including rs1800497 ANKK1 and rs1799732 DRD2 polymorphisms, eating behavior, hedonic hunger, and depressive symptoms. METHODS We retrospectively selected 101 patients who underwent BS and agreed to participate. The previous conditions to BS, such as body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure (DBP), and comorbidities, were registered; the scholarship value was evaluated as the total number of years of scholarly education. To evaluate the post-surgery conditions of the participants, we took blood samples, anthropometric measures, and 3 questionnaires to evaluate eating behavior (TFEQ-R18), hedonic hunger (PFS), and depressive symptoms (PHQ-9). The ANKK1 rs1800497 and rs1799732 DRD2 polymorphisms were genotyped. RESULTS The median total weight loss (TWL) was 34.7 kg, with a BMI of 33.8 kg/m2, 6 (4-8) years after BS. The TWL was positively associated with the TFEQ-R18 score (p = 0.006) and negatively associated with triglycerides (p = 0.011). rs1800497 ANKK1 was associated with TFEQ-R18 (OR = 1.13 (1.02-1.25), p = 0.009). We also found a negative correlation of pre-surgery BMI with scholarship (r = - 0.27, p < 0.05). CONCLUSION The patients showed an improvement in metabolic and anthropometric parameters post-surgery. Interestingly, the ANKK1 Taq1A polymorphism was associated with eating behavior and scholarship with pre-surgery BMI, which may be considered predictors of BS outcomes.

Abstract
INTRODUCTION Patients living with psychiatric illnesses (PIs) have a high prevalence of obesity. In a 2006 survey, 91.2% of professionals in the bariatric field identified "psychiatric issues" as clear contraindications to weight-loss surgery. METHODS This retrospective matched case-control study investigated the impact, safety, and possible relapse after bariatric metabolic surgery (BMS) in patients with PIs. Also, we tested the incidence of patients who developed PI after BMS and compared the post-procedural weight loss with that in a matched control group without PIs. The cases were matched in a ratio of 1:4 to the control patients standardized for age, sex, preoperative BMI, and type of BMS. RESULTS Of 5987 patients, 2.82% had a preoperative PI; postoperative de novo PI was present in 0.45%. Postoperative BMI was significantly different between the groups when compared to preoperative BMI (p < 0.001). Percentage of total weight loss (%TWL) after six months was not significantly different between the case (24.6% ± 8.9) and control groups (24.0% ± 8.4, p = 1.000). Early and late complications were not significantly different between the groups. The psychiatric drug use and dosage changes did not differ significantly pre- and postoperatively. Of the psychiatric patients, 5.1% were postoperatively admitted to a psychiatric hospital (p = 0.06) unrelated to BMS, and 3.4% had a prolonged absence from work after surgery. CONCLUSION BMS is an effective weight loss treatment and a safe procedure for patients with psychiatric disorders. We found no change in the patients' psychiatric status outside the usual disease course. Postoperative de novo PI was rare in the present study. Furthermore, patients with severe psychiatric illness were excluded from undergoing surgery and, therefore, from the study. Careful follow-up is necessary to guide and protect patients with PI.

Milkshake Acutely Stimulates Dopamine Release in Ventral and Dorsal Striatum in Healthy-Weight Individuals and Patients with Severe Obesity Undergoing Bariatric Surgery: A Pilot Study. Nutrients 2023; 15:2671. [PMID: 37375579 DOI: 10.3390/nu15122671] [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: 04/27/2023] [Revised: 05/31/2023] [Accepted: 06/06/2023] [Indexed: 06/29/2023] Open
Abstract
The overconsumption of palatable energy-dense foods drives obesity, but few human studies have investigated dopamine (DA) release in response to the consumption of a palatable meal, a putative mediator of excess intake in obesity. We imaged [11C]raclopride in the brain with positron emission tomography (PET) to assess striatal dopamine (DA) receptor binding pre- and post-consumption of a highly palatable milkshake (250 mL, 420 kcal) in 11 females, 6 of whom had severe obesity, and 5 of whom had healthy-weight. Those with severe obesity underwent assessments pre- and 3 months post-vertical sleeve gastrectomy (VSG). Our results demonstrated decreased post- vs. pre-meal DA receptor binding in the ventral striatum (p = 0.032), posterior putamen (p = 0.012), and anterior caudate (p = 0.018), consistent with meal-stimulated DA release. Analysis of each group separately suggested that results in the caudate and putamen were disproportionately driven by meal-associated changes in the healthy-weight group. Baseline (pre-meal) DA receptor binding was lower in severe obesity than in the healthy-weight group. Baseline DA receptor binding and DA release did not change from pre- to post-surgery. The results of this small pilot study suggest that milkshake acutely stimulates DA release in the ventral and dorsal striatum. This phenomenon likely contributes to the overconsumption of highly palatable foods in the modern environment.

Eating disorders and emotional dysregulation are associated with insufficient weight loss after bariatric surgery: a 1-year observational follow-up study. Eat Weight Disord 2023; 28:49. [PMID: 37266717 DOI: 10.1007/s40519-023-01574-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/31/2023] [Accepted: 05/14/2023] [Indexed: 06/03/2023] Open
Abstract
PURPOSE Subjects with obesity, especially those seeking bariatric surgery, exhibit high rates of mental disorders and marked psychopathological traits. The primary objective of this prospective, non-interventional study was to investigate whether the presence of different psychiatric disorders, attention deficit/hyperactivity disorder (ADHD) symptomatology and emotional dysregulation influenced weight loss at 1-year follow-up after surgery. METHODS Subjects consecutively referred for pre-surgical evaluation at the Obesity Center of Pisa University Hospital were recruited. Psychiatric diagnoses were made through the Mini-International Neuropsychiatric Interview (MINI) and ADHD symptomatology was assessed with the Wender-Reimherr Adult Attention Deficit Disorder Scale (WRAADDS). Emotional dysregulation was investigated through the WRAADDS and self-report questionnaires. After surgery, weight and obesity-related comorbidities were monitored during follow-up. RESULTS Of the 99 participants recruited, 76 underwent surgery and 65 could be reevaluated 1 year after surgery. Subjects with insufficient weight loss (excess body mass index loss ≤ 53%, n = 15) had more frequent lifetime binge eating disorder (BED) and BED-mood disorders comorbidity than subjects with favorable post-surgical outcome. Additionally, they scored higher on both physician-administered and self-report scales assessing emotional dysregulation, which represents a nuclear symptom of ADHD in adults. At the logistic regression analysis, older age, higher preoperative excess body mass index and greater affective instability were predictors of reduced weight loss at 1-year follow-up. CONCLUSION Emotional dysregulation seems to be associated with a worse outcome after bariatric surgery. Further studies with larger samples and longer follow-up are needed to confirm the influence of different psychiatric disorders and psychopathological traits on post-surgical outcome. LEVEL OF EVIDENCE V, prospective descriptive study.

Abstract
OBJECTIVE To examine whether depression status before metabolic and bariatric surgery (MBS) influenced 5-year weight loss, diabetes, and safety/utilization outcomes in the PCORnet Bariatric Study. SUMMARY OF BACKGROUND DATA Research on the impact of depression on MBS outcomes is inconsistent with few large, long-term studies. METHODS Data were extracted from 23 health systems on 36,871 patients who underwent sleeve gastrectomy (SG; n=16,158) or gastric bypass (RYGB; n=20,713) from 2005-2015. Patients with and without a depression diagnosis in the year before MBS were evaluated for % total weight loss (%TWL), diabetes outcomes, and postsurgical safety/utilization (reoperations, revisions, endoscopy, hospitalizations, mortality) at 1, 3, and 5 years after MBS. RESULTS 27.1% of SG and 33.0% of RYGB patients had preoperative depression, and they had more medical and psychiatric comorbidities than those without depression. At 5 years of follow-up, those with depression, versus those without depression, had slightly less %TWL after RYGB, but not after SG (between group difference = 0.42%TWL, P = 0.04). However, patients with depression had slightly larger HbA1c improvements after RYGB but not after SG (between group difference = - 0.19, P = 0.04). Baseline depression did not moderate diabetes remission or relapse, reoperations, revision, or mortality across operations; however, baseline depression did moderate the risk of endoscopy and repeat hospitalization across RYGB versus SG. CONCLUSIONS Patients with depression undergoing RYGB and SG had similar weight loss, diabetes, and safety/utilization outcomes to those without depression. The effects of depression were clinically small compared to the choice of operation.

Abstract
PURPOSE This study investigated the impact of either Roux-en-Y gastric bypass with silastic ring (SR-RYGB) or sleeve gastrectomy (SG) types of bariatric surgery on psychological health and explored the role of pre-existing depressive symptoms on weight loss. MATERIALS AND METHODS A total of 114 participants with obesity and type 2 diabetes were randomized to receive SR-RYGB or SG at a single centre. Data from the Hospital Anxiety and Depression Scale (HADS), RAND 36-item Health Survey and body weight were collected before surgery and annually for 5 years. RESULTS Sixteen patients were lost to follow-up at 5 years. Of the 98 patients who completed 5-year psychological follow-up assessments, 13 had mild to severe depressive symptoms (SR-RYGB n = 6, SG n = 7). SR-RYGB and SG resulted in similar psychological health improvement but percent weight loss at 5 years was greater for SR-RYGB by 10.6% (95% CI: 7.2 to 14.0, P < 0.0001). Scores for depressive symptoms and most RAND-36 domains improved significantly from baseline to 5 years in both groups. Patients with pre-existing depressive symptoms had similar percent weight loss at 5 years compared to patients without depressive symptoms, irrespective of procedural type. CONCLUSION Patients receiving either SR-RYGB or SG had comparable psychosocial functioning, which was maintained to 5 years post-surgery. Pre-existing depressive symptoms did not affect weight loss achieved at 5 years. These findings confirm previous longitudinal studies demonstrating that bariatric surgery is generally associated with improved psychosocial functioning.

Abstract
We present the case of a 42-year-old female with major depressive disorder who received a Roux-en-Y gastric bypass and subsequently decompensated in her depression symptoms and began newly engaging in problematic alcohol use. Top experts in the consultation-liaison field, specifically bariatric surgery psychiatry, provide guidance for this commonly encountered clinical case based on their experience and a review of the available literature. Key teaching points include the presurgical psychosocial assessment, pertinent perioperative psychopharmacology, and problematic alcohol use after bariatric surgery.

Abstract
Background Obesity negatively impacts mental and physical health and is a leading cause of disease worldwide. Obesity affects 33% of Saudi adults, with 10% being morbidly obese (body mass index, BMI >40 kg/m2). This study explored the association between bariatric surgery (BS) and a predisposition or exacerbation of depressive and anxiety symptoms. Material and methods A cross-sectional study of patients who underwent bariatric surgery at the King Khalid University Hospital in Riyadh, Saudi Arabia, was conducted between February 2016 and December 2021. The patients were contacted by phone to complete a self-administered questionnaire on demographic information, chronic medical diseases, psychiatric diseases, body mass index, and type of bariatric surgery. In addition, they completed the patient health questionnaire-9 (PHQ-9) and general anxiety disorder-7 (GAD-7) questionnaire to screen for patients' depression and anxiety symptoms. Results The findings of the 367 BS patients showed that 20.7% of the patients were considered to have mild anxiety, 11.2% had moderate anxiety, and 8.7% had high anxiety levels. However, regarding depression, 46.9% had extremely low levels of depression, followed by mild depression in 29.4% and moderate depression in 11.2%. Furthermore, another 8.2% of BS patients had moderately high depression levels, and 4.4% had severe depression. The anxiety and depression levels of the patients in this study did not show any statistically significant changes postoperatively in the short, medium, or long term. On the other hand, almost all of the patients 97% who underwent bariatric surgery were satisfied with the outcome of their surgery. Conclusion Few BS patients had high symptoms of depression and anxiety. We recommend pre- and postoperative psychiatric assessment for all bariatric surgery patients as surgical protocol.

Abstract
OBJECTIVE To examine associations of objectively-measured free-living physical activity (PA) with changes in depressive symptoms and mental and physical health-related quality of life (HRQoL) over 7 years after Roux-en-Y gastric bypass surgery (RYGB). BACKGROUND The contributions of PA to improvements in mental and physical health after RYGB, independent of weight loss, are unclear. METHODS Adults undergoing RYGB in a US multi-center cohort study wore an activity monitor and completed the Beck depression inventory (BDI) and 36-Item Short Form Health Survey (SF-36) annually ≤7 years (N = 646; 78% female, median age 47 years, median body mass index 46kg/m 2 ). Linear mixed models estimated associations of quartiles of steps, sedentary behavior (SB), and moderate-to-vigorous intensity physical activity (MVPA), respectively, with pre-to-post-surgery changes in the BDI and SF-36 mental component summary and physical component summary scores, respectively, over 1-7 years post-surgery, with adjustment for sex, age, race, pre-surgerybody mass index, the respective pre-surgery score, treatment for depression (time-varying) and pre-to-post-surgery weight change (time-varying). RESULTS There were dose-response associations between steps, SB (inverse) and MVPA quartiles, respectively, with improvements in each score. Across follow-up, mean improvements in the BDI, Mental Component Summary and physical component summary scores, were 1.9 [95% confidence interval (CI), 1.0-2.8], 3.1 (95% CI, 1.5-4.7), and 4.0 (95% CI, 2.7-5.4) points higher, respectively, in the highest versus lowest steps quartile. CONCLUSION Among adults who underwent RYGB, multiple objective PA measures were associated with decreases in depressive symptoms and improvements in mental and physical HRQoL throughout 7 years, independent of weight loss, indicating PA is a modifiable behavior to augment outcomes.

A Positive Emotion-Focused Intervention to Increase Physical Activity After Bariatric Surgery: Protocol for a Pilot Randomized Controlled Trial. JMIR Res Protoc 2022; 11:e39856. [PMID: 36201380 PMCID: PMC9585441 DOI: 10.2196/39856] [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: 05/26/2022] [Revised: 09/05/2022] [Accepted: 09/21/2022] [Indexed: 11/24/2022] Open
Abstract
Background Physical activity levels after bariatric surgery are usually low, despite the significant protective health benefits of physical activity in this population. Positive psychological well-being is associated with improved adherence to health behaviors, but bariatric surgery patients often have negative associations with physical activity that prevent sustained engagement. Objective The Gaining Optimism After weight Loss Surgery (GOALS) pilot randomized controlled trial is aimed at testing a novel intervention to increase physical activity after bariatric surgery, which incorporates positive psychological skill-building with motivational interviewing and goal-setting. Methods The GOALS trial is a 2-arm, 24-week pilot randomized controlled trial that aims to enroll 58 adults who report less than 200 minutes per week of moderate to vigorous physical activity and a desire to become more active 6-12 months after bariatric surgery. GOALS is testing the feasibility, acceptability, and preliminary efficacy of a positive psychology–motivational interviewing telephone intervention targeting to increase physical activity and associated positive affect. Intervention components include positive psychology, goal-setting, self-monitoring via provided Fitbits, and motivational interviewing to overcome barriers and increase motivation. The intervention is compared to a physical activity education control that includes mailings with psychoeducation around physical activity and provision of a Fitbit. The primary outcomes of the pilot trial are feasibility and acceptability, measured as session completion rates and participant ratings of ease and helpfulness of each session. The main secondary outcome is change in accelerometer-measured moderate to vigorous physical activity post intervention and at 24-week follow-up. Additional outcomes include changes in attitudes related to physical activity, psychological well-being, and physical health measures. Results This multiphase project was funded in 2020 and institutional review board approval was obtained for the proposed trial in 2021. Recruitment for the randomized controlled trial began in July 2022. Upon completion of the pilot trial, we will examine the feasibility, acceptability, and preliminary efficacy of the intervention. Conclusions Although bariatric surgery is the most effective treatment available for severe obesity, weight regain occurs, often in the context of low psychological well-being. Many individuals would benefit from learning strategies to increase positive psychological well-being after bariatric surgery, which could help them maintain lifestyle changes. Positive psychology is a novel approach to improve adherence by increasing positive associations with health behaviors including physical activity. The GOALS pilot trial will determine whether this type of intervention is feasible and acceptable to this population and will provide a foundation for a future full-scale randomized controlled efficacy trial.

The Factor Structure and Stability of the Beck Depression Inventory-II (BDI-II) in a Population Undergoing Bariatric Surgery. Obes Surg 2022; 32:3732-3739.

Abstract
PURPOSE Depression is a multifaceted psychiatric condition that has been associated with suboptimal weight loss following bariatric surgery. Previous variations of Beck Depression Inventory-Second Edition (BDI-II) subscales been proposed, including those identified within bariatric populations; however, it is unclear whether the BDI-II items contained within these subscales would remain consistent after the procedure considering the physical and lifestyle changes that occur following bariatric surgery. MATERIALS AND METHODS A two-step analytic approach that comprised of exploratory (EFA) and confirmatory factor analyses (CFA) that aimed to identify a stable factor structure using pre- and 6-month post-surgical BDI-II responses. Baseline BDI-II responses of 149 patients (Group 1) were used to identify an initial EFA model. Five BDI-II models underwent CFA using BDI-II responses of a comparable pre-surgical group (Group 2; n = 142), and 6-month post-surgical data from Group 1. RESULTS EFA generated a two-factor solution. Of the five CFA models performed, the three-factor model that was initially identified by Hayes (2015) among patients undergoing bariatric surgery demonstrated superior fit across time and between groups. CONCLUSIONS Although the EFA initially identified a two-factor model, CFA determined that a previously defined three-factor model reliably fit both pre- and post-surgical BDI-II responses. This study supports using the Hayes (2015) subscales when monitoring pre- and post-bariatric surgery facets of depression specific to this population. Being able to accurately and reliably monitor depressive symptoms of patients that are undergoing bariatric surgery will allow for the provision and monitoring of targeted interventions aimed at improving their mental and physical health outcomes.

Abstract
BACKGROUND Depression and overweight/obesity often cooccur but the underlying neural mechanisms for this bidirectional link are not well understood. METHODS In this functional magnetic resonance imaging study, we scanned 54 individuals diagnosed with depressive disorders (DD) and 48 healthy controls (HC) to examine how diagnostic status moderates the relationship between body mass index (BMI) and brain activation during anticipation and pleasantness rating of food versus nonfood stimuli. RESULTS We found a significant BMI-by-diagnosis interaction effect on activation in the right inferior frontal gyrus (RIFG) and anterior cingulate cortex (ACC) during food versus nonfood anticipation (p < .0125). Brain activation in these regions was greater in HC with higher BMI than in HC with lower BMI. Individuals with DD showed an opposite pattern of activation. Structural equation modeling revealed that the relationship between BMI, activation in the RIFG and ACC, and participants' desire to eat food items shown in the experiment depended on the diagnostic status. CONCLUSIONS Considering that food anticipation is an important component of appetitive behavior and that the RIFG and ACC are involved in emotion regulation, response inhibition and conflict monitoring necessary to control this behavior, we propose that future clinical trials targeting weight loss in DD should investigate whether adequate mental preparation positively affects subsequent food consumption behaviors in these individuals.

Abstract
OBJECTIVE In a large multisite cohort of Veterans who underwent Roux-en-Y gastric bypass (RYGB) or laparoscopic sleeve gastrectomy (LSG), initiation of (ie, incident) and persistence of (ie, continuation of preoperative) depression treatment are compared with matched nonsurgical controls. BACKGROUND Bariatric surgery has been associated with short-term improvements in depression but less is known about longer term outcomes. METHODS In a retrospective cohort study, we matched 1713 Veterans with depression treatment who underwent bariatric surgery in Veterans Administration bariatric centers from fiscal year 2001 to 2016 to 15,056 nonsurgical controls using sequential stratification and examined the persistence of depression treatment via generalized estimating equations. Incidence of depression treatment was compared using Cox regression models between 2227 surgical patients and 20,939 matched nonsurgical controls without depression treatment at baseline. RESULTS In surgical patients with depression treatment at baseline, the use of postsurgical depression treatment declined over time for both surgical procedures, but postsurgical patients had greater use of depression treatment at 5 years [RYGB: odds ratio=1.24, 95% confidence interval (CI): 1.04-1.49; LSG: odds ratio=1.27, 95% CI: 1.04-1.56] compared with controls. Among those without depression treatment at baseline, bariatric surgery was associated with a higher incidence of depression treatment compared with matched controls (RYGB: hazard ratio=1.34, 95% CI: 1.17-1.53; LSG: hazard ratio at 1-5 years=1.27, 95% CI: 1.10-1.47). CONCLUSIONS Bariatric surgery was associated with a greater risk of postoperative incident depression treatment and greater persistence of postoperative depression treatment. Depression may worsen for some patients after bariatric surgery, so clinicians should carefully monitor their patients for depression postoperatively.

Abstract
Purpose Bariatric surgery is an efficacious intervention for substantial and sustained weight reduction in individuals with morbid obesity resulting in health improvements. However, the changes to a patient’s health related quality of life (HRQoL) in the medium to longer term after bariatric surgery have not been adequately characterized. Our aim was to evaluate the change to patient HRQoL 5 years following bariatric surgery in an Australian government-funded hospital system and determine the significance of relationships between change in physical and mental assessment scores and HRQoL utility scores. Materials and Methods We performed a longitudinal panel study of 81 adult patients who underwent primary bariatric surgery at an Australian tertiary government-funded hospital and completed multi-attribute utility (MAU), multi-attribute non-utility (MA), and disease-specific adjusted quality of life (AQoL) questionnaires before and after bariatric surgery. Results At a mean (SD) 5.72 (1.07) years postbariatric surgery, participants demonstrated statistically significant improvements in mean AQoL-8D utility (0.135 (0.21); P < 0.0001), yielding a mean 3.2 (1.67) QALYs gained. Beck Depression Inventory-II scores improved (baseline mean 17.35 (9.57); 5-year mean 14.7 (11.57); P = 0.037). Short Form-36 scores improved in the domains of physical functioning and role limitations due to physical health and general health. Change in depression scores and patient satisfaction with surgery were found to be significant predictors of follow up AQoL utility scores. Conclusions Bariatric surgery improves physical and psychological quality of life measures over 5 years. The improvement of patient QALYs provide insight to the potential cost utility of publicly funded bariatric surgery in the medium term. Graphical abstract ![]()

Abstract
Mental Health Disorders (MHD) are a growing concern nationwide. The significant impact MHD have on surgical outcomes has only recently started to be understood. This literature review investigated how mental health impacts the outcomes of general surgery patients and what can be done to make improvements. Patients with schizophrenia had the poorest surgical outcomes. Mental health disorders increased post-surgical pain, hospital length of stay, complications, readmissions, and mortality. Mental health disorders decreased wound healing and quality of care. Optimizing outcomes will be best accomplished through integrating more effective perioperative screening tools and interventions. Screenings tools can incorporate artificial intelligence, MHD data, resilience and its biomarkers, and patient mental health questionnaires. Interventions include cognitive behavioral therapy, virtual reality, spirituality, pharmacology, and resilience training.

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.

The Impact of Telephone-Based Cognitive Behavioral Therapy on Mental Health Distress and Disordered Eating Among Bariatric Surgery Patients During COVID-19: Preliminary Results from a Multisite Randomized Controlled Trial. Obes Surg 2022; 32:1884-1894. [PMID: 35218006 PMCID: PMC8880302 DOI: 10.1007/s11695-022-05981-6] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2021] [Revised: 02/16/2022] [Accepted: 02/17/2022] [Indexed: 11/30/2022]
Abstract
Background Patients undergoing bariatric surgery have high rates of psychiatric comorbidity, which may increase their vulnerability to COVID-19-related mental health distress. Exacerbation of mental health distress and disordered eating could have significant negative effects on long-term weight management and quality of life for these patients if untreated. Objective To determine the efficacy of a telephone-based cognitive behavioral therapy (Tele-CBT) intervention in improving depressive, anxiety, and disordered eating symptoms during COVID-19. Methods Participants were recruited as part of a larger randomized controlled trial study (clinicaltrials.gov ID: NCT03315247) between March 2020 and March 2021 and randomized 1:1 to receive Tele-CBT or standard bariatric care. Outcomes of Generalized Anxiety Disorder-7 (GAD-7), Patient Health Questionnaire-9 (PHQ-9), Emotional Eating Scale (EES), and Binge Eating Scale (BES) were measured at baseline, immediately post-intervention, and 3 months post-intervention. Linear mixed models were used to test the effect of intervention group, time, and group-by-time interaction for each outcome. Results Eighty-one patients were included in the intention-to-treat analysis. Mean (SD) age of participants was 47.68 (9.36) years and 80.2% were female. There were significant group-by-time interactions for all outcomes and significant differences between groups across time. There were significant decreases in mean GAD-7 (p = 0.001), PHQ-9 (p < 0.001), EES-Total (p = 0.001), EES-Anger (p = 0.003), EES-Anxiety (p < 0.001), EES-Depression (p < 0.001), and BES (p = 0.002) scores for the Tele-CBT group at post-intervention and follow-up when compared to baseline and the control group. Conclusion Tele-CBT is a feasible and effective treatment for improving psychological distress and disordered eating among post-operative bariatric surgery patients during the COVID-19 pandemic.

Effect of Obesity Surgery on Taste. Nutrients 2022; 14:nu14040866. [PMID: 35215515 PMCID: PMC8878262 DOI: 10.3390/nu14040866] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/01/2021] [Revised: 02/07/2022] [Accepted: 02/15/2022] [Indexed: 12/03/2022] Open
Abstract
Obesity surgery is a highly efficacious treatment for obesity and its comorbidities. The underlying mechanisms of weight loss after obesity surgery are not yet fully understood. Changes to taste function could be a contributing factor. However, the pattern of change in different taste domains and among obesity surgery operations is not consistent in the literature. A systematic search was performed to identify all articles investigating gustation in human studies following bariatric procedures. A total of 3323 articles were identified after database searches, searching references and deduplication, and 17 articles were included. These articles provided evidence of changes in the sensory and reward domains of taste following obesity procedures. No study investigated the effect of obesity surgery on the physiological domain of taste. Taste detection sensitivity for sweetness increases shortly after Roux-en-Y gastric bypass. Additionally, patients have a reduced appetitive reward value to sweet stimuli. For the subgroup of patients who experience changes in their food preferences after Roux-en-Y gastric bypass or vertical sleeve gastrectomy, changes in taste function may be underlying mechanisms for changing food preferences which may lead to weight loss and its maintenance. However, data are heterogeneous; the potential effect dilutes over time and varies significantly between different procedures.

Abstract
PURPOSE OF REVIEW We review evidence for assessing and monitoring psychotropic medications in metabolic and bariatric surgery (MBS) patients. We describe weight gain side effects, potential perioperative risks, pharmacokinetic changes that occur after MBS, and conclude with clinical recommendations. RECENT FINDINGS Research on psychiatric medication use and post-MBS weight outcomes is lacking and inconsistent; however, there is consistent evidence that, though variable, psychiatric medication use is associated with weight gain. Several meta-analyses and reviews provide guidance on lowering risk when appropriate. Perioperative lithium toxicity and SSRI discontinuation syndrome also warrant consideration, as do potential post-operative pharmacokinetic changes. In the absence of data for each psychiatric drug classification, close symptom monitoring and, where appropriate, serum concentration monitoring are recommended. MBS patients are a psychiatrically vulnerable population, and many are on psychiatric medications. Given potential weight/metabolic side effects, perioperative complications, and post-operative pharmacokinetic changes that occur with psychotropic medication use, providers should stay well informed on psychiatric medication management considerations.

Abstract
PURPOSE A considerable number of post-bariatric surgery patients report problematic eating behaviors (PEBs) and/or eating disorders (EDs). Examining psychosocial variables associated with ED symptoms may identify targets for postoperative interventions to reduce these behaviors and improve surgical outcomes. METHODS A total of 161 participants completed the Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF) and the Eating Disorder Examination-Questionnaire (EDE-Q). Participants were classified into ED risk or no ED risk groups and subjective binge eating (SBE) or no SBE groups. Independent-sample t tests were computed to examine mean differences in total weight loss (%TWL) and MMPI-2-RF scale scores between the ED groups. Relative Risk Ratios (RRRs) were computed to determine which MMPI-2-RF scales were associated with increased risk of ED group membership. RESULTS The ED risk group lost significantly less weight (19.36% TWL) than the no ED risk group (25.18% TWL). The SBE group lost significantly less weight (17.98% TWL) than the no SBE group (25.57% TWL). Participants in the ED groups scored significantly higher on internalizing and externalizing MMPI-2-RF scales than the no ED groups. These scales were associated with increased risk (1.55-2.55 times the risk) of being classified into the ED groups. CONCLUSIONS Patients who experienced postoperative ED symptoms lost significantly less weight than patients without ED symptoms. Postoperative ED symptoms are related to, and may be impacted by, higher levels of internalizing and externalizing dysfunction after surgery. Postoperative assessment of and interventions targeting psychosocial dysfunction could decrease ED symptoms. LEVEL OF EVIDENCE III: Evidence obtained from well-designed cohort or case-control analytic studies.

Abstract
BACKGROUND With the rapid increase in the incidence of depression, there have been studies investigating whether bariatric surgery can alleviate this condition. In this study, we aimed to explore the effect of bariatric surgery on depression in obese patients. METHODS We searched the PubMed, Embase, Web of Science and the Cochrane Library databases for studies on bariatric surgery and depression. Then, the clinical significance of bariatric surgery on depression was evaluated based on Beck Depression Inventory (BDI), Hospital Anxiety and Depression Scale (HADS) or Patient Health Questionnaire (PHQ-9). Subgroup analysis was carried out in terms of surgery types, assessment tool, follow-up time and nationalism. Dichotomous data were analyzed using odds ratio (OR), and continuous data were evaluated using the weighted mean difference (WMD) or standardized mean difference (SMD). RESULTS Overall, 33 studies with a combined total of 12,556 participants met the inclusion criteria. Statistical results were significantly different whether continuous or dichotomous, and depression was improved in obese patients after surgery (SMD = -0.87, p < 0.001; and OR = 0.29, p < 0.001, respectively). In addition, subgroup analysis showed that bariatric surgery improved depression in obese patients regardless of surgery types, assessment tool, follow-up and country. CONCLUSION Bariatric surgery alleviates depression in obese patients. However, further studies are needed to elucidate on the complex effect of between bariatric surgery on depression.

Abstract
AIMS We aimed to examine if bariatric surgery was associated with a reduction in the prevalence of depressive and anxiety symptoms among people with obesity. MATERIALS AND METHODS We pooled data from 49 studies involving 11,255 people with obesity who underwent bariatric surgery. The study outcomes were the prevalence of depressive and anxiety symptoms among these patients pre- and post-surgery. RESULTS There was a significant reduction in body mass index (BMI) post-operatively (pooled d+: -13.3 kg/m2 [95% confidence interval [CI] 15.19, -11.47], p < 0.001). The pooled proportion of patients with anxiety symptoms reduced from 24.5% pre-operatively to 16.9% post-operatively, with an odds ratio (OR) of 0.58 (95% CI 0.51, 0.67, p < 0.001). The reduction remained significant in women aged ≥40 years and irrespective of post-operative BMI. There were significant reductions in Hospital Anxiety and Depression Score (HADS) (anxiety component) by 0.64 (pooled d+: -0.64 [95% CI -1.06, -0.22], p = 0.003) and Generalized Anxiety Disorder Assessment-7 score by 0.54 (pooled d+: -0.54 [95% CI -0.64, -0.44], p < 0.001). The pooled proportion of depressive symptoms reduced from 34.7% pre-operatively to 20.4% post-operatively, with an OR of 0.49 (95% CI 0.37, 0.65, p < 0.001). The reduction remained significant irrespective of patient's age and post-operative BMI. There were also significant reductions in HADS score (depressive component) (pooled d+: -1.34 [95% CI -1.93, -0.76], p < 0.001), Beck's Depression Inventory score (pooled d+: -1.04 [95% CI -1.46, -0.63], p < 0.001) and Patient Health Questionnaire-9 score (pooled d+: -1.11 [95% CI -1.21, -1.01], p < 0.001). CONCLUSION Bariatric surgery was associated with significant reduction in the prevalence and severity of depressive and anxiety symptoms among people with obesity.

Abstract
INTRODUCTION Bariatric surgery is safe and efficient surgical method for weight loss, but it is not free from complications. We aim to evaluate the prevalence of depression after Sleeve Gastrectomy (SG) in a narrow period of time on Iranian ethnicity. METHODS 307 cases that underwent SG in Erfan Niayesh hospital were included. The questionnaire was based on International Classification of Diseases, Ninth Revision (ICD-9) codes to define diagnoses. Screening follow-up period was 20 to 24 months. The level of statistical significance was set at p < .05. RESULTS Of 307 subjects, preoperative depression was 30.2% and post-operative depression was 37.7% (p = .025). Besides, BMI, dyslipidaemia, good feelings about body size and weight loss were statistically significant at p < .05.There was an increased risk of depression following the procedure mainly in divorced cases. CONCLUSION The prevalence of clinical depression after sleeve gastrectomy was statistically significant and dependent on other variables. We provided guidance for people considering SG and their clinicians in terms of evaluating potential risks and benefits of surgery.

Abstract
Bariatric surgery induces sustained weight loss and metabolic benefits via notable effects on the gut-brain axis that lead to alterations in the neuroendocrine regulation of appetite and glycaemia. However, in a subset of patients, bariatric surgery is associated with adverse effects on mental health, including increased risk of suicide or self-harm as well as the emergence of depression and substance use disorders. The contributing factors behind these adverse effects are not well understood. Accumulating evidence indicates that there are important links between gut-derived hormones, microbial and bile acid profiles, and disorders of mood and substance use, which warrant further exploration in the context of changes in gut-brain signalling after bariatric surgery. Understanding the basis of these adverse effects is essential in order to optimize the health and well-being of people undergoing treatment for obesity.

Defining minimal clinically important differences in pain and disability outcomes of patients with chronic pain treated with spinal cord stimulation. J Neurosurg Spine 2021; 35:243-250. [PMID: 34087802 DOI: 10.3171/2020.11.spine201431] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2020] [Accepted: 11/10/2020] [Indexed: 11/06/2022]
Abstract
OBJECTIVE Minimal clinically important difference (MCID) thresholds for a limited number of outcome metrics were previously defined for patients with failed back surgery syndrome (FBSS) at 6 months after spinal cord stimulation (SCS). This study aimed to further define MCID values for pain and disability outcomes. Additionally, the authors established 1-year MCID values for outcome measures with previously defined metrics commonly used to assess SCS efficacy. METHODS Preoperative and 1-year postoperative outcomes were collected from 114 patients who received SCS therapy for FBSS, complex regional pain syndrome, and neuropathic pain. MCID values were established for the numerical rating scale (NRS), Oswestry Disability Index (ODI), Beck Depression Inventory (BDI), McGill Pain Questionnaire (MPQ), and Pain Catastrophizing Scale (PCS). Four established anchor-based methods were utilized to compute MCID values with two anchored questions: "Are you satisfied with SCS therapy?" and "Would you have SCS surgery again?" For each question, patients were categorized as responders if they answered "yes" or as nonresponders if they responded "no." The methodologies utilized to compute MCID scores included the average change method, minimum detectable change approach, change difference calculation, and receiver operating characteristic (ROC) analysis. Area under the ROC curve (AUC) analysis has been shown to inform the accuracy at which the MCID value can distinguish responders from nonresponders and was analyzed for each instrument. RESULTS For the first time, ranges of MCID values after SCS were established for MPQ (1-2.3) and PCS (1.9-13.6). One-year MCID values were defined for all indications: NRS (range 0.9-2.7), ODI (3.5-6.9), and BDI (2-5.9). AUC values were significant for NRS (0.78, p < 0.001), ODI (0.71, p = 0.003), MPQ (0.74, p < 0.001), and PCS (0.77, p < 0.001), indicating notable accuracy for distinguishing satisfied patients. CONCLUSIONS This was the first study to successfully determine MCID values for two prominent instruments, MPQ and PCS, used to assess pain after SCS surgery. Additionally, previously established MCID values for ODI, BDI, and the visual analog scale for patients with FBSS at 6 months after treatment were explored at 12 months for the most common indications for SCS. These data may better inform physicians of patient response to and success with SCS therapy.

Abstract
OBJECTIVE Bariatric surgical procedures are being commonly performed increasingly, and many surgical candidates are concomitantly taking psychotropic medication. This paper aims to elucidate issues when prescribing psychiatric medication in this setting of substantial anatomical and physiological change. METHOD A hand search of the literature to assess the current understanding of effects of various bariatric procedures on the bioavailability of psychotropic medication. RESULTS Predominantly malabsorptive bariatric procedures may reduce bioavailability of some but not all commonly used psychiatric medications. There is minimal information about the effects of the most commonly performed surgery, vertical sleeve gastrectomy. Lithium prescription and monitoring requires caution. CONCLUSIONS There is limited guidance for prescription for psychotropic medication in the bariatric surgery patient group, and vigilance for unexpected adverse effects or altered efficacy is warranted.

Abstract
PURPOSE Metabolic and bariatric surgery (MBS) is increasingly used in adolescents. The aim was to explore symptoms of depression and anxiety in young adults over 5 years' follow-up after undergoing MBS. METHODS Beck Depression Inventory-2 and the Beck Anxiety Inventory were used to assess symptoms of depression and anxiety in 62 patients 1, 2, and 5 years after having Roux-en-Y gastric bypass at 13-18 years of age. Mental health, eating-related problems, and weight outcomes were tested for association with suicidal ideation at the 5-year follow-up. RESULTS At the 5-year follow-up, the mean score for depression was 11.4 (± 12.4), indicating minimal symptoms of depression. The mean score for anxiety was 12.82 (± 11.50), indicating mild anxiety symptoms. Still, several participants reported moderate or severe symptoms of depression (26%) and anxiety (32%). Women reported more symptoms than men (P = 0.03 and 0.04). No significant changes were found in self-reported symptoms of depression and anxiety between the 1-year and the 5-year follow-up (P = 0.367 and 0.934). Suicidal ideation was reported by 16% at the 5-year follow-up. Participants reporting suicidal ideation had lost significantly less excess weight than participants without suicidal ideation (P = 0.009). CONCLUSION Five years after adolescent MBS, a substantial minority still struggles with mental health issues, and women are more burdened than men. Our results indicate an association between less optimal weight loss and suicidal ideation 5 years after MBS. The findings emphasize the importance of offering long-term follow-up and mental health treatment several years after MBS. LEVEL OF EVIDENCE Level III, cohort study. CLINICAL TRIAL REGISTRATION The study is registered with ClinicalTrials.gov (NCT00289705). First posted February 10, 2006.

Abstract
Diet is a modifiable factor that ensures optimal growth, biochemical performance, improved mood and mental functioning. Lack of nutrients, notably vitamin B, has an impact on human health and wellbeing. The United Arab Emirates is facing a serious problem of micronutrient deficiencies because of the growing trend for bariatric surgery, including Roux-en-Y gastric bypass and sleeve gastrectomy. People undergoing bariatric surgery are at high risk of developing neurological, cognitive, and mental disabilities and cardiovascular disease due to deficiency in vitamin B. Vitamin B is involved in neurotransmitter synthesis, including γ-aminobutyric acid, serotonin, dopamine, and noradrenaline. Deficiency of vitamin B increases the risk of depression, anxiety, dementia and Alzheimer's disease. In addition, vitamin B deficiency can disrupt the methylation of homocysteine, leading to hyperhomocysteinemia. Elevated homocysteine levels are detrimental to human health. Vitamin B deficiency also suppresses immune function, increases the production of pro-inflammatory cytokines and upregulates NF-κB. Considering the important functions of vitamin B and the severe consequences associated with its deficiency following bariatric surgery, proper dietary intervention and administration of adequate supplements should be considered to prevent negative clinical outcomes.

Abstract
OBJECTIVE To assess the association between having a serious mental illness and surgical outcomes for adults, including in-hospital and 30-day mortality, post-operative complications, and hospital length of stay. STUDY DESIGN Systematic review and meta-analysis of publications in English to 30 July 2018 of studies that examined associations between having a serious mental illness and surgical outcomes for adults who underwent elective surgery. Primary outcomes were in-hospital and 30-day mortality, post-operative complications, and length of hospital stay. Risk of bias was assessed with the Quality in Prognosis Studies (QUIPS) tool. Studies were grouped by serious mental illness diagnosis and outcome measures. Odds ratios (ORs) or mean differences (MDs), with 95% confidence intervals (CIs), were calculated in random effects models to provide pooled effect estimates. DATA SOURCES MEDLINE, EMBASE, PsychINFO, and the Cochrane Library. DATA SYNTHESIS Of the 3824 publications identified by our search, 26 (including 6 129 806 unique patients) were included in our analysis. The associations between having any serious mental illness diagnosis and having any post-operative complication (ten studies, 125 624 patients; pooled effect: OR, 1.44; 95% CI, 1.15-1.79) and a longer stay in hospital (ten studies, 5 385 970 patients; MD, 2.6 days; 95% CI, 0.8-4.4 days) were statistically significant, but not those for in-hospital mortality (three studies, 42 926 patients; OR, 1.21; 95% CI, 0.69-2.12) or 30-day mortality (six studies, 83 013 patients; OR, 1.85; 95% CI, 0.86-3.99). CONCLUSIONS Having a serious mental illness is associated with higher rates of post-operative complications and longer stays in hospital, but not with higher in-hospital or 30-day mortality. Targeted pre-operative interventions may improve surgical outcomes for these vulnerable patients. SYSTEMATIC REVIEW REGISTRATION PROSPERO, CRD42018080114 (prospective).

"If you're offered help, take it": A qualitative study examining bariatric patients' experience of telephone-based cognitive behavioural therapy. Clin Obes 2021; 11:e12431. [PMID: 33251753 DOI: 10.1111/cob.12431] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/27/2020] [Revised: 10/26/2020] [Accepted: 11/05/2020] [Indexed: 12/28/2022]
Abstract
The increased recognition of patients' mental health needs after bariatric surgery has resulted in the emergence of accessible psychosocial interventions; however, there is a dearth of literature on patient experience and satisfaction with these interventions. We explored patients' perceptions and experiences of telephone-based cognitive behavioural therapy (Tele-CBT) in this qualitative study. Ten participants from the Toronto Western Hospital Bariatric Surgery Program in Toronto, Canada who completed the Tele-CBT (ClinicalTrials.gov Identifier: NCT02920112) were individually interviewed from November 2014 to June 2016 until thematic saturation occurred (ie, no more new coding groups emerged). Interviews were transcribed, independently coded, checked for discrepancies, and analysed using grounded theory. Four themes emerged: (1) participants were generally satisfied with Tele-CBT (eg, therapeutic alliance, resources provided, relevance of therapy to their own bariatric journey), (2) participants noticed emotional, cognitive, and behavioural changes following therapy, (3) the optimal time to deliver the Tele-CBT was when weight loss plateaued, generally at one-year post-surgery, and (4) participants found the telephone modality convenient. CBT was generally found to be helpful and the telephone format increased convenience and accessibility. Patients reported learning skills and receiving resources that could help them improve their well-being following bariatric surgery.

Eating behaviors and weight outcomes in bariatric surgery patients amidst COVID-19. Surg Obes Relat Dis 2021; 17:1165-1174. [PMID: 33812789 PMCID: PMC7908843 DOI: 10.1016/j.soard.2021.02.025] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2020] [Revised: 02/10/2021] [Accepted: 02/18/2021] [Indexed: 12/13/2022]
Abstract
Background Recent studies suggest that eating habits are an area particularly affected by the lockdown imposed by many countries to curb the COVID-19 epidemic. Individuals that received bariatric surgery may represent a particularly susceptible population to the adverse effects of lockdown for its potential impact on eating, psychological, and weight loss outcomes. Objectives This study seeks to investigate the incremental impact of COVID-19 lockdown on treatment outcomes of postbariatric patients in the risk period for weight regain. Setting Main hospital center. Methods This work uses data from an ongoing longitudinal study of bariatric patients assessed before surgery (T0), 1.5 years after sugery (T1), and 3 years after surgery (T2). Two independent groups were compared: the COVID-19_Group (n = 35) where T0 and T1 assessments were conducted before the pandemic started and T2 assessment was conducted at the end of the mandatory COVID-19 lockdown; and the NonCOVID-19_Group (n = 66), covering patients who completed T0, T1, and T2 assessments before the epidemic began. Assessment included self-report measures for disordered eating, negative urgency, depression, anxiety, stress, and weight outcomes. Results General linear models for repeated measures showed that the COVID-19_Group presented significantly higher weight concern (F = 8.403, P = .005, ƞ2p = .094), grazing behavior (F = 7.166, P = .009, ƞ2p = .076), and negative urgency (F = 4.522, P = .036, ƞ2p = .05) than the NonCOVID-19_Group. The COVID-19_Group also showed less total weight loss (F = 4.029, P = .05, ƞ2p = .04) and larger weight regain at T2, with more COVID-19_Group participants experiencing excessive weight regain (20% versus 4.5%). Conclusion These results show evidence for the impact of the coronavirus outbreak on eating-related psychopathology and weight outcomes in postbariatric surgery patients.

The Complex Association Between Bariatric Surgery and Depression: a National Nested-Control Study. Obes Surg 2021; 31:1994-2001. [PMID: 33537948 PMCID: PMC8041688 DOI: 10.1007/s11695-020-05201-z] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2020] [Revised: 12/21/2020] [Accepted: 12/29/2020] [Indexed: 11/17/2022]
Abstract
Background Although bariatric surgery has been shown to reduce weight loss and obesity-related conditions, an improvement in depression remains unclear. The aim of this study was to determine whether bariatric surgery is associated with a resolution of depression, and the prevention of its onset. Method Patients with a BMI ≥ 30 kg/m2 who had undergone bariatric surgery were identified from the Clinical Practice Research Datalink (CPRD), matched 5:1 to controls. Cox regression analysis was used to determine the risk of developing de novo depression. Kaplan-Meier analysis compared the proportion of patients with no further consultations related to depression between the two groups. Results In total, 3534 patients who underwent surgery, of which 2018 (57%) had pre-existing depression, were matched to 15,480 controls. Cox proportional hazard modelling demonstrated surgery was associated with a HR of 1.50 (95% CI 1.32–1.71, p < 0.005) for developing de novo depression. For those with pre-existing depression, by 5 years, just over 20% of post-surgical patients had no further depression episodes compared with 17% of controls. Conclusion In individuals with a history of depression, bariatric surgery is associated with an improvement in mental health. On the contrary, the finding of increased de novo diagnoses of depression following surgery indicates the need for further study of the mechanisms by which bariatric surgery is associated with depression in this subset of patients.

Associations between binge eating, depressive symptoms and anxiety and weight regain after Roux-en-Y gastric bypass surgery. Eat Weight Disord 2021; 26:191-199. [PMID: 31898239 DOI: 10.1007/s40519-019-00839-w] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/24/2019] [Accepted: 12/17/2019] [Indexed: 12/11/2022] Open
Abstract
BACKGROUND Weight regain (WR) after bariatric surgery (BS) is frequent. OBJECTIVE The aim of this study was to evaluate whether the occurrence of psychiatric disorders would be associated with short- and long-term WR after BS. METHODS Ninety-six patients (77.6% female, age 40.2 ± 10.1 years, BMI of 50 ± 8.2 kg/m2) from the Obesity and Bariatric Surgery Outpatient Clinic of the Universidade Federal São Paulo completed the Questionnaire on Eating and Weight Patterns-Revised, the Beck Depression Inventory and an anxiety inventory to assess the occurrence of binge eating, depressive symptoms (DS) and anxious symptoms (AS) before and after short-term and long-term BS. RESULTS Twenty-four months after BS, the prevalence of binge eating, depression and anxiety decreased from 100 to 13%, 100 to 15% and 43 to 4%, respectively. The mean WR of 35.2 ± 17.3% of weight loss occurred in nine patients after 24 months and was associated with binge eating (p = 0.002) but not with DS or AS. At long-term follow-up (12 ± 1.5 years), 67% had a mean WR of 50.3 ± 24.9%. The prevalence of binge eating, DS and AS were 48%, 46% and 63%, respectively, in this group, and significant associations were observed between WR and binge eating (p = 0.001), DS (p = 0.029) and AS (p = 0.001). Furthermore, the number of psychiatric disorders was inversely associated with the percentage of weight loss (p < 0.05) and positively associated with WR (p < 0.05). CONCLUSION Weight regain was associated with the occurrence of binge eating in the short and long term after BS, whereas the occurrence of depressive and anxious symptoms was associated with WR only in the long term. LEVEL III Evidence obtained from well-designed cohort or case-control analytic studies.

Six-year bariatric surgery outcomes: the predictive and incremental validity of presurgical psychological testing. Surg Obes Relat Dis 2021; 17:1008-1016. [PMID: 33640259 DOI: 10.1016/j.soard.2021.01.012] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2020] [Revised: 01/05/2021] [Accepted: 01/17/2021] [Indexed: 11/16/2022]
Abstract
BACKGROUND Research identifying preoperative psychosocial predictors of bariatric surgery outcomes has yielded inconsistent results with minimal examination of longer-term outcomes. Utilizing a broadband measure of personality and psychopathology during the preoperative evaluation helps to identify preoperative risk factors for suboptimal bariatric surgery outcomes. OBJECTIVE Examine predictors of outcome and the incremental contribution of presurgical psychological testing to various long-term bariatric surgery outcomes. SETTING Academic medical center. METHOD A total of 168 postoperative patients (average of 6 postoperative years) consented to participate in the outcome study. Participants were weighed by the trained research/clinical staff and completed a battery of self-report questionnaires, including measures assessing eating attitudes and behaviors and weight-related quality-of-life (QoL). Patients had completed the Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF) as part of the institution's routine preoperative psychosocial evaluation. Weight loss was calculated as percent total weight loss (%TWL) and percent weight regain (%WR) was calculated as a percentage of maximum weight loss. Other preoperative data were obtained from a review of each patient's electronic medical record (EMR). From the initial sample, 145 patients were retained for analyses in the present study. RESULTS Preoperative problematic eating variables predicted long-term postoperative problematic eating behaviors and body image concerns. Scores on preoperative MMPI-2-RF scales measuring Demoralization, Dysfunctional Negative Emotions, Antisocial Behaviors, and Hypomanic Activation were consistent incremental predictors of 6-year outcomes, accounting for an additional 3%-24% of the variability in postoperative eating behaviors and QoL. CONCLUSIONS The preoperative psychological evaluation can be used to identify predictors of long-term bariatric surgery outcomes. Identification of these risk factors provides important targets for pre- and postoperative clinical interventions to maximize surgical outcomes.

Abstract
Obesity is a common outcome of traumatic brain injury (TBI) that exacerbates principal TBI symptom domains identified as common areas of post-TBI long-term dysfunction. Obesity is also associated with increased risk of later-life dementia and Alzheimer's disease. Patients with obesity and chronic TBI may be more vulnerable to long-term mental abnormalities. This review explores the question of whether weight loss induced by bariatric surgery could delay or perhaps even reverse the progression of mental deterioration. Bariatric surgery, with its induction of weight loss, remission of type 2 diabetes, and other expressions of the metabolic syndrome, improves metabolic efficiency, leads to reversal of brain lesions seen on imaging studies, and improves function. These observations suggest that metabolic/bariatric surgery may be the most effective therapy for TBI.
