Risk of Suicide and Self-harm Is Increased After Bariatric Surgery-a Systematic Review and Meta-analysis

'Surgery is my only hope': A qualitative study exploring perceptions of living with obesity and the prospect of having bariatric surgery

The health benefits of bariatric surgery are well documented; however, the occurrence of weight-regain after surgery, along with the development of mental health difficulties poses a question of how contemporary psychology could assist to prepare people living with obesity prior to undergoing bariatric surgery. This research explored individuals' (in the immediate pre-operative and post-operative population) attitudes, beliefs and experiences towards obesity and their journey to bariatric surgery. Seventeen adult participants (males n = 4; age range: 26-64 years) were recruited and participated in a semi-structured interview. Twelve individuals participated prior to undergoing bariatric surgery. Five individuals participated in the early post-operative period (<3 months post-surgery). People living with obesity displayed high optimism for positive outcomes, with participants hoping that bariatric surgery would be different to previous attempts at weight regulation, with there being a clear shift in the locus of control for weight management from self to healthcare professionals. Whilst this is adaptive, there was the presence of seemingly unrealistic optimism, with many pre-surgery participants not relaying the realistic possibility of post-surgery weight-regain. Despite the optimism individuals feel about bariatric surgery, participants felt that the psychological factors influencing eating behaviours are not being addressed by healthcare. These findings suggest that mindfulness, mindful eating, and self-compassion approaches should be incorporated into clinical practice to support weight regulation and adaption to physiological changes after bariatric surgery.

Impact of antidepressant use on post-operative weight loss following bariatric surgery

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.

No association between history of psychiatric treatment and postoperative weight reduction after bariatric surgery

PURPOSE

The objective of the study was to assess whether the history of psychiatric treatment was associated with (1) body weight and BMI on admission for bariatric surgery, (2) weight loss > 5 kg prior to bariatric surgery, and (3) postoperative body weight reduction.

METHODS

Data from medical records of all consecutive patients admitted for surgical treatment of obesity in the 2nd Department of General Surgery Jagiellonian University Medical College were obtained. There were 1452 records of patients who underwent bariatric surgery between 2009 and 2021 included in the study.

RESULTS

History of psychiatric treatment was found in 177 (12%) of the sample and was inversely associated with body weight and BMI on admission for surgery in women. Men with history of psychiatric treatment were 54% less likely to lose > 5 kg before the surgery (OR = 0.46 95% CI = 0.24-0.88). Both in men and women %TWL did not differ significantly by history of psychiatric treatment (Me: 40.7 vs. 45.9; p = 0.130 and Me: 27.0 vs. 23.9; p = 0.383, respectively). After adjustment for covariates no association was found between history of psychiatric treatment and body weight reduction one year after surgery.

CONCLUSION

Although men with preoperative history of psychiatric treatment had lower odds of losing weight before the surgery, psychiatric treatment did not differentiate the effectiveness of bariatric treatment in 1 year of observation. Bariatric surgery appears to be an effective obesity care for people treated for mental disorders.

Approach to Obesity Treatment in Primary Care: A Review

Importance

More than 40% of US adults have obesity, which increases the risks for multiple chronic diseases and premature mortality. Historically, nonsurgical interventions often have not led to sufficient weight loss and maintenance to improve health, but highly effective antiobesity medications (AOMs) have recently become available, and additional effective therapeutics are under development. Given that most medical care for adults with obesity is delivered in primary care settings, guidance for integrating weight-management approaches is needed.

Observations

Lifestyle interventions can lead to a mean weight loss of 2% to 9% of initial weight at 1 year and increase the likelihood of weight loss of 5% or more, but weight regain over time is common even with continued treatment. Adjunctive treatments, including AOMs and surgical approaches, can lead to larger, more sustained weight loss and improvements in numerous obesity-associated medical conditions. Highly effective AOMs, including nutrient-stimulated hormone-based therapies, induce mean weight loss of 15% or more. Barriers to intervention, including access to care, have a disproportionate influence on populations most affected by obesity and its consequences.

Conclusions and Relevance

Primary care clinicians play a vital role in the assessment, management, and support of patients with obesity. With careful clinical assessment and shared decision-making, a flexible treatment plan can be developed that reflects evidence of treatment efficacy, patient preference, and feasibility of implementation. Adjunctive therapies to lifestyle interventions, including more effective pharmacotherapeutics for obesity, offer hope to patients and the potential for considerable improvements in health and quality of life.

Psychopathology, disordered eating, and impulsivity as predictors of weight loss 24 months after metabolic and bariatric surgery

BACKGROUND

The relationship between theoretically relevant psychosocial and behavioral variables and outcomes of metabolic and bariatric surgery remains unclear. Some studies have found that the presence of psychopathology, disordered eating, and impulsivity, either before surgery or during the early postoperative period, is associated with suboptimal postoperative weight loss. Other studies have not found these relationships.

OBJECTIVE

Examine the relationship between psychopathology, disordered eating, impulsivity, and weight loss 24 months postoperatively.

SETTING

Two large, urban university health systems.

METHODS

Participant characteristics were collected using validated interviews, patient-reported outcome measures, and computerized assessment methods. Linear mixed effect models were used to test the association of the variables of interest on percent weight loss (%WL).

RESULTS

Three hundred participants were enrolled at baseline; weight data at 24 months were available for 227 participants; between 181 and 53 individuals completed other outcome measures. The mean %WL was 23.3 ± 9.9% at 24 months. Patients who underwent Roux-en-Y gastric bypass lost more weight than those who underwent sleeve gastrectomy. The presence of subjective binge episodes at baseline was related to a greater %WL at 24 months; there were no other baseline predictors. The presence of eating disorder diagnoses and disordered eating symptoms after surgery were associated with smaller weight losses over 24 months. Current and lifetime psychopathology and impulsivity were unrelated to %WL at 24 months.

CONCLUSION

Disordered eating after bariatric surgery was associated with a smaller %WL at postoperative year 2. Additional monitoring of these symptoms in the early postoperative period is recommended. Psychotherapeutic and/or dietary interventions may promote more optimal weight loss outcomes.

Association of semaglutide with risk of suicidal ideation in a real-world cohort

Concerns over reports of suicidal ideation associated with semaglutide treatment, a glucagon-like peptide 1 receptor (GLP1R) agonist medication for type 2 diabetes (T2DM) and obesity, has led to investigations by European regulatory agencies. In this retrospective cohort study of electronic health records from the TriNetX Analytics Network, we aimed to assess the associations of semaglutide with suicidal ideation compared to non-GLP1R agonist anti-obesity or anti-diabetes medications. The hazard ratios (HRs) and 95% confidence intervals (CIs) of incident and recurrent suicidal ideation were calculated for the 6-month follow-up by comparing propensity score-matched patient groups. The study population included 240,618 patients with overweight or obesity who were prescribed semaglutide or non-GLP1R agonist anti-obesity medications, with the findings replicated in 1,589,855 patients with T2DM. In patients with overweight or obesity (mean age 50.1 years, 72.6% female), semaglutide compared with non-GLP1R agonist anti-obesity medications was associated with lower risk for incident (HR = 0.27, 95% CI = 0.200.32-0.600.36) and recurrent (HR = 0.44, 95% CI = 0.32-0.60) suicidal ideation, consistent across sex, age and ethnicity stratification. Similar findings were replicated in patients with T2DM (mean age 57.5 years, 49.2% female). Our findings do not support higher risks of suicidal ideation with semaglutide compared with non-GLP1R agonist anti-obesity or anti-diabetes medications.

Suicide attempts after bariatric surgery: comparison to a nonsurgical cohort of individuals with severe obesity

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.

Analysis of the Efficacy of Diet and Short-Term Probiotic Intervention on Depressive Symptoms in Patients after Bariatric Surgery: A Randomized Double-Blind Placebo Controlled Pilot Study

(1) Background: studies have shown that some patients experience mental deterioration after bariatric surgery. (2) Methods: We examined whether the use of probiotics and improved eating habits can improve the mental health of people who suffered from mood disorders after bariatric surgery. We also analyzed patients' mental states, eating habits and microbiota. (3) Results: Depressive symptoms were observed in 45% of 200 bariatric patients. After 5 weeks, we noted an improvement in patients' mental functioning (reduction in BDI and HRSD), but it was not related to the probiotic used. The consumption of vegetables and whole grain cereals increased (DQI-I adequacy), the consumption of simple sugars and SFA decreased (moderation DQI-I), and the consumption of monounsaturated fatty acids increased it. In the feces of patients after RYGB, there was a significantly higher abundance of two members of the Muribaculaceae family, namely Veillonella and Roseburia, while those after SG had more Christensenellaceae R-7 group, Subdoligranulum, Oscillibacter, and UCG-005. (4) Conclusions: the noted differences in the composition of the gut microbiota (RYGB vs. SG) may be one of the determinants of the proper functioning of the gut-brain microbiota axis, although there is currently a need for further research into this topic using a larger group of patients and different probiotic doses.

Bariatric surgery and mental health outcomes: an umbrella review

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.

[Prevention and management of postinterventional weight regain]

Decreasing levels of patient motivation or compliance are far from being the only causes of postinterventional weight regain after lifestyle, psychological, pharmacological and surgical interventions. Weight regain originates from a complex and individually varying set of central and peripheral mechanisms, with the overall purpose of increasing food intake by both stimulating hunger and reducing satiety (mediated by gastrointestinal hormones) and decreasing the body's energy demands (via metabolic adaption). These mechanisms counteract any attempts to reduce or maintain body weight in today's increasingly prevalent adipogenic environments. The knowledge about the biological mechanisms of body weight regulation should be taken into consideration when planning treatment programs for long-term weight reduction, including follow-up treatment for the prevention and individualized treatment of postinterventional weight regain. Therapeutic measures as well as the frequency of medical follow-ups should be based on the extent of weight regain.

Long-term weight loss outcomes after bariatric surgery: a propensity score study among patients with psychiatric disorders

INTRODUCTION

To analyze the safety and long-term result of bariatric surgery in patients with psychiatric disorders.

MATERIAL AND METHODS

From January 2009 to December 2018, n = 961 patients underwent bariatric surgery in a tertiary center. Among them, two groups of patients were created: a group of patients with psychiatric disorders (PG) and a group without psychiatric disorders (CG), using a propensity score matched (PSM). Primary endpoint was long-term outcomes and secondary endpoints were the postoperative morbidity 90 days after surgery, late morbidity, occurrence of psychiatric adverse events, and resolution of obesity-related comorbidities.

RESULTS

Analysis with PSM permitted to compare 136 patients in each group, with a ratio 1:1. TWL% at 2 years in the PG was 32.7% versus 36.6% in the CG (p = 0.002). Overall surgical morbidity was higher in the PG than the CG (28% vs 17%, p = 0.01). Severe surgical complications were not statistically significant (4% vs 3%, p = 0.44). Psychiatric adverse events were significantly more frequent in the PG than in the CG. The resolution of obesity comorbidities was equivalent for both groups at 2 years.

CONCLUSION

Substantial weigh loss was reported among patients with psychiatric disorders receiving bariatric surgery at the cost of more non-severe surgical complications. Further, a psychiatric postoperative follow-up visit may be warranted for patients with preoperative psychiatric disorders, given the incidence of psychiatric adverse events.

Clostridium butyricum Strain CCFM1299 Reduces Obesity via Increasing Energy Expenditure and Modulating Host Bile Acid Metabolism

Clostridium butyricum is a butyrate-producing microorganism which has beneficial effects on various diseases, including obesity. In our previous study, the anti-obesity Clostridium butyricum strain CCFM1299 (C20_1_1) was selected, but its anti-obesity mechanism was not clarified. Herein, CCFM1299 was orally administrated to high-fat-diet-treated C57BL/6J mice for 12 weeks to uncover the way the strain alleviates obesity. The results indicated that CCFM1299 alleviated obesity through increasing the energy expenditure and increasing the expression of genes related to thermogenesis in brown adipose tissue (BAT). Moreover, strain CCFM1299 could also affect the expression of immune-related genes in epididymal white adipose tissue (eWAT). This immunomodulatory effect might be achieved through its influence on the complement system, as the expression of the complement factor D (CFD) gene decreased significantly. From the view of metabolites, CCFM1299 administration increased the levels of ursodeoxycholic acid (UDCA) in feces and taurohyodeoxycholic acid (THDCA) in serum. Together, the anti-obesity potential of CCFM1299 might be attributed to the increase in energy consumption, the regulation of immune-related gene expression in eWAT, and the alteration of bile acid metabolism in the host. These provided new insights into the potential application of anti-obesity microbial preparations and postbiotics.

The forgotten patient: A psychological perspective on the implementation of bariatric surgery guidelines

There is strong evidence demonstrating the impact of bariatric surgery on weight-loss and comorbidity improvement. In the UK, there is specific guidance to facilitate the assessment of a person's suitability for bariatric surgery. This paper highlights the clinical reality of routinely implementing this guidance, supported by literature and the perspectives of practicing psychologists. The consequences of the implementation of clinical guidelines within the context of the typical biopsychosocial profile of those referred for bariatric surgery are discussed. The ramifications of a screening approach rather than a clinical formulation-based approach to assessment, impact of a possible unconscious bias in commissioning and an overemphasis on a biomedical model approach to treatment are also presented. These contextual factors are argued to contribute to a population of "forgotten patients" that is, patients who have been assessed as not suitable for bariatric surgery, and thus "stuck" in their journey toward better health. For these individuals the only option left are energy balance only approaches, which are the very same approaches to weight-loss and comorbidity improvement that have been attempted, often for many years. Not only have these approaches not resulted in weight-loss and health improvement, they also fail to address the underlying psychological causes of obesity. Consequently, this lack of support means that patients continue to suffer from poor quality of life, with no clear pathway to improved health and wellbeing. This paper illuminates the clear gaps in weight management service provision, the implementation of guidelines in practice, and offers practical suggestions to reduce the unintended consequences of clinical guidelines for bariatric surgery.

Bariatric surgery and reproduction-implications for gynecology and obstetrics

As the rates of obesity continue to rise across the world, there has been an increasing resort to bariatric surgery amongst the options for treatment. Through the reproductive lifespan, between menarche and menopause, women might benefit from this surgical intervention, which may have a bearing on other aspects of their health. The consequences of bariatric surgery have been reported and evaluated from various perspectives in obstetrics and gynecology. Fertility and sexuality are enhanced, but not all gynecological diseases are ameliorated. There are also psychological and behavioral sequelae to be cognizant of. With multi-disciplinary and responsive care, most post-bariatric pregnancies have satisfactory outcomes. The effects of bariatric surgery on the babies conceived thereafter remains a subject of interest, whereas the possible effect on the climacteric is speculative.

Causes of revisional surgery, reoperations, and readmissions after bariatric surgery

INTRODUCTION AND OBJECTIVES

Bariatric surgery is the most effective treatment for weight loss, with comorbidity control. With low complication rates, the reasons for reoperation are major complications or weight loss failure/weight regain. Nonsurgical problems can also present, such as anemia, dehydration, chronic pain, and malnutrition, among others. Our aim was to analyze the main causes of revisional surgery, reoperation, and hospital readmission, at a specialized bariatric center.

METHODS

A retrospective study was conducted on patients that underwent bariatric surgery within the time frame of 2012 and 2019. The baseline analysis included demographic, anthropometric, and perioperative data, as well as a sub-analysis of the main readmission causes and complications.

RESULTS

A total of 776 primary surgeries were performed (649 RYGBP, 127 SG, and 10 revisional surgeries), and 99 patients were identified for the study: 10 revisional surgeries, 44 reoperations, and 45 readmissions. The incidence of revisional surgery was 1.2%, reoperation was 5.6%, and readmission 5.8%. Fifty percent of the revisional surgeries were performed due to insufficient weight loss or weight regain; the most frequent causes of reoperation were cholecystitis (38.6%) and internal hernias (9.1%); and the most common causes of readmission were nonspecific abdominal pain (35.5%) and dehydration (24.4%).

CONCLUSION

The most frequent causes of postoperative readmission were nonsurgical events, followed by non-bariatric reoperations, and finally revisional surgeries. There was a low incidence of early reoperations. Knowledge of the abovementioned data is important for identifying higher-risk patients, to prevent major complications.

Incidence of adverse mental health outcomes after sleeve gastrectomy compared with gastric bypass and restrictive bariatric procedures: a retrospective cohort study

OBJECTIVE

This study examined rates of suicide and hospitalization with psychiatric diagnoses after sleeve gastrectomy compared with gastric bypass and restrictive procedures (gastric banding/gastroplasty).

METHODS

This was a longitudinal retrospective cohort study comprising all patients who underwent primary bariatric surgery in New South Wales or Queensland, Australia, between July 2001 and December 2020. Hospital admission records, death registration, and cause of death records (if applicable) within these dates were extracted and linked. Primary outcome was death by suicide. Secondary outcomes were admissions with self-harm; substance-use disorder, schizophrenia, mood, anxiety, behavioral, and personality disorders; any of these; and psychiatric inpatient admission.

RESULTS

A total of 121,203 patients were included, with median follow-up of 4.5 years per patient. There were 77 suicides, with no evidence of difference in rates by surgery type (rates [95% CI] per 100,000 person years: 9.6 [5.0-18.4] restrictive, 10.8 [8.4-13.9] sleeve gastrectomy, 20.4 [9.7-42.8] gastric bypass; p = 0.18). Rates of admission with self-harm declined after restrictive and sleeve procedures. Admission with anxiety disorders, any psychiatric diagnosis, and as a psychiatric inpatient increased after sleeve gastrectomy and gastric bypass, but not restrictive procedures. Admissions with substance-use disorder increased after all surgery types.

CONCLUSIONS

Variable associations between bariatric surgeries and hospitalization with psychiatric diagnoses might indicate distinct vulnerabilities among patient cohorts or that differing anatomical and/or functional changes may contribute to effects on mental health.

Screening Risks of Alcohol Abuse, Depressive Symptoms, and Decreased Health-Related Quality of Life in Post-Bariatric Patients and Their Relations to Weight Regain

PURPOSE

Not all patients who underwent bariatric surgery keep their regular medical follow-up. We screened alcohol use, depressive symptoms, and health-related quality of life (HRQoL) in post-bariatric patients who have lost medical follow-up at their first appointment in our healthcare unit. These screened disorders were compared between low vs. high ratios of weight regain (RWR) and correlated with surgical outcomes.

MATERIAL AND METHODS

Ninety-four post-bariatric patients without medical follow-up (87.2% female, aged 42 ± 9 years, BMI = 32.9 ± 6.5kg/m²) were included. They underwent Roux-en-Y gastric bypass (n = 80) or sleeve gastrectomy (n = 14). They were divided into high RWR (≥ 20%) and low RWR (< 20%) groups. We used Alcohol Use Disorders Inventory Test, Beck Depression Inventory, and 36-Item Short-Form Health Survey.

RESULTS

Neck and waist circumferences, diastolic blood pressure, and time since surgery were higher in the high than low RWR group (P≤ 0.05). No differences between groups for alcohol use and depressive symptoms were detected (P≥ 0.07), but those who regained more weight exhibited poorer health scores in physical functioning, physical role limitations, bodily pain, and vitality (P≤ 0.05). In the low RWR group, the RWR was inversely correlated to physical/social functioning and vitality. Positive associations were present between RWR vs. depressive symptoms, while negative ones were noted to physical functioning and general health perception in the high RWR group.

CONCLUSIONS

HRQoL has deteriorated in those post-bariatric patients without medical follow-up who regained more weight, possibly indicating the need for regular long-term health care.

Challenges of Treating ADHD with Comorbid Substance Use Disorder: Considerations for the Clinician

Adults with attention deficit/hyperactivity disorder (ADHD) often present psychiatric comorbidities and, in particular, substance use disorder (SUD). ADHD-SUD comorbidity is characterized by greater severity of both disorders, earlier age of onset, higher likelihood of polydrug-abuse and suicidal behaviors, more hospitalizations, and lower treatment adherence. At the present stage, research focused on the pharmacological management of ADHD with comorbid SUD in both adolescents and adults is still lacking. Furthermore, while the short-term effects of stimulants are well studied, less is known about the chronic effects of these drugs on dopamine signaling. Current available evidence is consistent in reporting that high doses of stimulant medications in ADHD-SUD subjects have a mild to moderate efficacy on ADHD symptoms. Some data suggest that pharmacological treatment with stimulants may be beneficial for both ADHD symptoms and comorbid cocaine or amphetamine use. However, in the long run, stimulant medications may have a potential risk for misuse. For the absence of potential misuse, atomoxetine is often recommended for ADHD with comorbid cocaine or amphetamine use disorder. However, its efficacy in reducing addictive behavior is not demonstrated. In subjects with other subtypes of SUD, both atomoxetine and stimulant drugs seem to have scarce impact on addictive behavior, despite the improvement in ADHD symptomatology. In this population, ADHD treatment should be combined with SUD-specific strategies.

Suicide in Deep Brain Stimulation for Parkinson's Disease: A Retrospective Case-Control Study

 Deep brain stimulation (DBS), a treatment of Parkinson's disease (PD), has been associated with suicidality. We conducted a case-control study comparing suicide in four pairs of cohorts: PD patients with DBS or not, epilepsy patients with resection surgery or not, subjects with BMI≥30 with bariatric surgery or not, and patients with chronic kidney disease with transplantation or not. PD patients with DBS demonstrated a lower risk of suicide relative to PD patients without DBS. Findings from other elective surgeries indicate that patients receiving operative treatments do not possess predictable differences in suicide rates relative to their medically managed counterparts.

Binge eating, depressive symptoms and suicidal ideation in obese candidates for bariatric surgery

PURPOSE

The aim of the present study was to determine possible associations between binge eating, depressive symptoms and suicidal ideation in obese candidates for bariatric surgery.

METHODS

A cross-sectional study was conducted with 254 obese patients recruited from the general surgery service for bariatric procedures at the hospital affiliated with the Federal University of Pernambuco, Brazil. Evaluations were performed using the Binge Eating Scale (BES), Beck Depression Inventory, Beck Scale for Suicidal Ideation (BSSI) and a questionnaire addressing sociodemographic characteristics.

RESULTS

Most patients were women (82%), 48% had a moderate binge eating disorder, 42% a severe binge eating disorder, 32% had symptoms suggestive of mild, moderate or severe depression and 6% had suicidal ideation. Severe binge eating was positively associated with depressive symptoms (p < 0.001) and suicidal ideation (p < 0.05). Cases of severe binge eating were more frequent in young adults, but not necessarily associated with symptoms of depression or suicidal ideation in this portion of the sample.

CONCLUSIONS

The present findings underscore the need for psychological and psychiatric follow-up of obese candidates for bariatric surgery using appropriate assessment scales to guide therapeutic approaches.

Prevalence of adverse childhood experiences and effect on outcomes in bariatric surgery patients: a systematic review and meta-analysis

Adverse childhood experiences (ACEs) are defined as childhood maltreatment (sexual, physical, and emotional abuse and neglect) and other childhood traumatic experiences. Published prevalence estimates for ACEs in bariatric samples vary greatly and evidence on the association between ACEs and bariatric surgery weight loss and psychosocial outcomes is inconclusive. A systematic literature search on PubMed/Medline, PsycInfo, Web of Science, CINAHL (Cumulative Index of Nursing and Allied Health Literature), and Open Grey for studies published until August 30, 2021, yielded 21 publications for qualitative synthesis: 20 reporting on prevalence of ACEs in bariatric surgery candidates and patients, and 10 on the association of ACEs with outcomes. In meta-analysis, overall moderate to high heterogeneity was observed for prevalence estimates and moderate heterogeneity was observed for associations. Prevalence estimate for at least 1 form of ACEs (6 studies, n = 1368 patients) was 51% (95% confidence interval [CI]: 32%-70%). Effect size (Hedge's g) for the difference between the groups of patients reporting any or a high number of ACEs versus no or a low number of ACEs was calculated from means, standard deviations and group size, or P values. Based on 7 studies (n = 946 patients), the association between ACEs and weight loss was not significant (Hedge's g = -.15 [95% CI: -.38 to .09]; I² = 53%), regardless of short- or long-term follow-up (P = .413) and the proportion of patients in each study receiving Roux-en-Y gastric bypass (RYGB) (β = .0005, P = .868). Preliminary findings based on 3 short- and long-term studies (n = 414 patients) showed that ACEs were significantly (P = .001) associated with higher postoperative depressive symptoms (Hedge's g = .50 [95% CI: .22-.78]; I² = 36%). Associations between ACEs and other psychosocial outcomes such as eating pathology were reported narratively. There is a need for additional long-term studies using validated assessment tools for ACEs to evaluate the effect of ACEs on weight and psychosocial outcomes after bariatric surgery.

Psychiatric, psychological and addiction management in obesity surgery: Early identification for better support

Although bariatric surgery results in a significant weight reduction and an improvement in the quality of life in most people who undergo surgery, there are inter-individual differences in terms of postoperative results. Psychological, psychiatric and addictive disorders contribute substantially to these difficulties. Between 20% and 50% of bariatric surgery candidates have a current psychiatric/addictive disorder and approximately 30-75% have a history of a psychiatric/addictive disorder within their lifetime. Surgery is accompanied in the short-term by an improvement in depressive symptoms and binge eating, but these symptoms tend to increase again beyond the 3rd postoperative year. Over the long-term, only the improvement in depression remains durable, whilepostoperative anxiety and disordered eating symptoms do not differ significantly from the preoperative levels. There is a two to four fold increased risk of post-surgical suicide and suicide attempts (from the 1st postoperative year onward), as well as an increased risk of alcohol-abuse (beyond two years after surgery). Psychological support must therefore continue long-term. Several psychotherapeutic and pharmacological treatments have demonstrated their effectiveness in improving the postoperative prognosis of patients with psychological/psychiatric disorders. The early integration of psychological/psychiatric/addiction evaluation and support into multidisciplinary management makes it easier to identify these difficulties and to optimize the postoperative prognosis, both in terms of weight and quality of life. Prior to surgery, patients should be systematically evaluated by a psychologist or psychiatrist in order to identify and to manage disorders that could negatively impact the postoperative prognosis. After surgery, this assessment and support can be carried out in a programmed and systematic way for those patients who were identified preoperatively as the most vulnerable, but support can also be offered during follow-up in the event of specific symptoms (i.e., loss of control over food intake, failure in terms of weight or quality of life, suicidal ideation, loss of control over alcohol use, significant depression or anxiety symptoms).

Ethics of Bariatric Surgery in Adolescence and Its Implications for Clinical Practice

Obesity is increasingly prevalent among adolescents. Clinical and research data support the use of bariatric surgery (BS) as a treatment option for severely obese adolescents, with good results in terms of weight loss, improvement or resolution of comorbidities, and compliance to follow up. Nevertheless, concerns still remain, with significant disparities among countries and ethical concerns mainly raised by performing an irreversible and invasive procedure in adolescence, with potential life-long alterations. In this context, the purpose of this narrative review was to discuss the main current ethical challenges in performing BS in adolescence and to inform appropriate clinical management in the field. The core ethical principles of autonomy, beneficence, nonmaleficence, and justice were revised in terms of patient-centered healthcare through the lens of psychosocial implications. The review concludes with a discussion regarding the potential directives for future research for effective, patient-centered, and ethical management of obesity in the adolescent population.

Incidence of self-harm after bariatric surgery: A nationwide registry-based matched cohort study

The aims of this study were to evaluate the longitudinal risk of self-harm and the risk factors for self-harm after bariatric surgery in patients and control subjects without prior self-harm. This observational cohort study was based on prospectively registered data. Patients 18-70 years at time of surgery, body mass index (BMI) > 30 kg/m² , who underwent a primary Roux-en-Y gastric bypass (RYGB) procedure or a primary sleeve gastrectomy between 2007 and 2019 were considered for inclusion. All patients who met the inclusion criteria were matched 1:10 to the general population in Sweden (69 492 patients vs. 694 920 controls). After excluding patients and controls with previous self-harm, a self-harm event occurred in 1408 patients in the surgical group (incidence rate (IR) 3.54/1000 person-years, 95% confidence interval (CI) 3.36-3.73) versus in 3162 patients in the control group (IR 0.81/1000 person-years, 95% CI 0.78-0.84), with a hazard ratio (HR) of 4.38 (95% CI 4.11-4.66, p < .001). Median follow-up time was 6.1 years. Risk factors were younger age, lower BMI, cardiovascular, and chronic obstructive pulmonary disease, all aspects of psychiatric comorbidities (except neuropsychiatric disorder), lower socioeconomic status, RYGB, lower health-related quality of life, lower postoperative weight loss, and not attending postoperative follow-up visits. Self-harm is clearly higher after bariatric surgery than in the general population. A qualitative follow-up may be particularly important for patients at increased risk.

"I was bullied for being fat in every situation, in every outfit, at every celebration": A qualitative exploratory study on experiences of weight-based oppression in Qatar

Introduction

Weight-based oppression (WBO) has been documented as a widespread phenomenon in Western countries and is associated with a range of psychological, physiological, and behavioral harms. Research on weight-based oppression is largely absent from the Arab region.

Methods

We conducted a qualitative exploratory study using semi-structured in-depth interviews to examine the internalized attitudes, values, and beliefs related to body weight, and experiences of external weight-based oppression of 29 staff, faculty, and students at Qatar University.

Results

Thematic analysis revealed six major themes on the characteristics of internalized WBO, and the nature, timing, source, extent, and impact of external WBO. WBO was regarded as so common in the Arab culture as to be normative, with damaging exposure to WBO beginning in early childhood.

Conclusion

WBO in the Arab region is an important and unrecognized public health issue. Programs to reduce WBO should be developed in all sectors.

Psychosocial Aspects of Metabolic and Bariatric Surgeries and Endoscopic Therapies

Obesity is a prevalent progressive and relapsing disease for which there are several levels of intervention, including metabolic and bariatric surgery (MBS) and now endoscopic bariatric and metabolic therapies (EBMTs). Preoperative psychological assessment focused on cognitive status, psychiatric symptoms, eating disorders, social support, and substance use is useful in optimizing patient outcomes and minimizing risks in MBS. Very little is known about the psychosocial needs of patients seeking EBMTs, though these investigations will be forthcoming if these therapies become more widespread. As MBS and EBMT inherently alter the gastrointestinal (GI) tract, considerations for the longer-term GI functioning of the patient are relevant and should be considered and monitored.

Depressive symptoms before and after abdominoplasty among post-bariatric patients - a cohort study

The majority of post-bariatric patients suffer from excess skin after weight loss, impairing physical, psychosocial and mental health. The abdomen is the most common location for excess skin, and abdominoplasty is the most commonly required reconstructive procedure. Abdominoplasty removes excess abdominal skin and attenuates related symptoms, but knowledge regarding mental health-related effects is scarce. Here, we aimed to evaluate the symptoms and severity of depression before and after abdominoplasty in post-bariatric patients and to analyse the relationships between depressive symptoms, quality of life (QoL) and experience of excess skin. We enrolled 110 former obese patients undergoing abdominoplasty. Three questionnaires evaluating the symptoms of depression (Beck Depression Inventory (BDI-II)), experience of excess skin (Sahlgrenska Excess Skin Questionnaire (SESQ)) and QoL (36-item Short-Form Health Survey (SF-36)) were completed preoperatively and 1 year postoperatively. After abdominoplasty, symptoms of depression (BDI sum score) significantly decreased (5.8 vs. 3.0, p = .037). Scores on three BDI questions improved (p < .05), and the SESQ score normalised (p < .001), while the SF-36 score was unaffected. The BDI sum score was moderately correlated with the SF-36 mental composite score (preoperatively, r_s = -0.69; postoperatively, r_s = -0.66) and fairly correlated with the SF-36 physical composite score (r_s = 0.32, r_s = 0.26). The correlation between the BDI sum and SESQ scores was poor preoperatively (r_s = -0.106) and fair postoperatively (r_s = 0.232). The results indicate that abdominoplasty may reduce symptoms of depression in post-bariatric patients. However, the procedure did not affect SF-36 scores. Further studies are required to validate these results.

Analysis of the Lack of Follow-Up of Bariatric Surgery Patients: Experience of a Reference Center

Few studies have evaluated the association between non-clinical and clinical determinants in terms of discontinuing follow-up after bariatric surgery. This cohort study aims to assess these associations. Data were collected from a prospectively maintained database of patients who underwent laparoscopic bariatric surgery from January 2012 to December 2019. The Cox model was used to assess the influence of preoperative determinants on follow-up interruptions for more than one year. Multilevel logistic regression was used to evaluate the association between clinical factors and post-operative weight loss with the regularity of follow-up. During the study period, 9607 consultations were performed on 1549 patients. The factors associated with a follow-up interruption from more than 365 days included male gender (HR = 1.323; CI = 1.146−1.527; p = 0.001) and more recent years of intervention (HR = 1.043; CI = 1.012−1.076; p = 0.0068). Revisional bariatric surgery was associated with a lower risk of follow-up interruption (HR = 0.753; CI = 0.619−0.916; p = 0.0045). Independent risk factors of an irregular follow up were higher age (HR = 1.01; CI = 1.002−1.017; p = 0.0086); male gender (OR = 1.272; CI = 1.047−1.545; p = 0.0153); and higher %TWL (Total Weight Loss) (OR = 1.040 CI = 1.033−1.048 p < 0.0001). A higher preoperative BMI (OR = 0.985; CI = 0.972−0.998; p = 0.0263) and revisional surgery (OR = 0.707; CI = 0.543−0.922; p = 0.0106) were protective factors of irregularity. This study suggests that the male gender and most recent dates of surgery are the two independent risk factors for follow-up interruption. Older age, male gender, and higher weight loss were all independent risk factors of an irregular follow-up. Revision bariatric surgery is a protective factor against interruption and irregular follow-up with a higher preoperative BMI. Further studies are needed to obtain long-term results in these patients with discontinued follow-ups.

Depression in non-alcoholic fatty liver disease is associated with an increased risk of complications and mortality

Background and aims

The global prevalence of non-alcoholic fatty liver disease (NAFLD) is expected to rise continuously. Furthermore, emerging evidence has also shown the potential for concomitant depression in NAFLD. This study aims to examine the prevalence, risk factors, and adverse events of depression in NAFLD and evaluate whether treated depression can reverse the increased risks of adverse outcomes.

Materials and methods

This study analyses the 2000–2018 cycles of NHANES that examined liver steatosis with fatty liver index (FLI). The relationship between NAFLD and depression was assessed with a generalized linear mix model and a sensitivity analysis was conducted in the no depression, treated depression, and untreated depression groups. Survival analysis was conducted with cox regression and fine gray sub-distribution model.

Results

A total of 21,414 patients were included and 6,726 were diagnosed with NAFLD. The risk of depression in NAFLD was 12% higher compared to non-NAFLD individuals (RR: 1.12, CI: 1.00–1.26, p = 0.04). NAFLD individuals with depression were more likely to be older, females, Hispanics or Caucasians, diabetic, and have higher BMI. Individuals with depression have high risk for cardiovascular diseases (CVD) (RR: 1.40, CI: 1.25–1.58, p < 0.01), stroke (RR: 1.71, CI: 1.27–2.23, p < 0.01), all-cause mortality (HR: 1.50, CI: 1.25–1.81, p < 0.01), and cancer-related mortality (SHR: 1.43, CI: 1.14–1.80, p = 0.002) compared to NAFLD individuals without depression. The risk of CVD, stroke, all-cause mortality, and cancer-related mortality in NAFLD individuals with treated depression and depression with untreated treatment was higher compared to individuals without depression.

Conclusion

This study shows that concomitant depression in NAFLD patients can increase the risk of adverse outcomes. Early screening of depression in high-risk individuals should be encouraged to improve the wellbeing of NAFLD patients.

The Factor Structure and Stability of the Beck Depression Inventory-II (BDI-II) in a Population Undergoing Bariatric Surgery

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.

Weight stigma and posttraumatic stress disorder symptoms in individuals seeking bariatric surgery

BACKGROUND

After bariatric surgery, some patients experience adverse psychiatric outcomes, including substance use, suicidality, and self-harm. These factors are commonly associated with posttraumatic stress disorder (PTSD) and related symptoms (PTSD-S) that develop following adverse childhood experiences (ACEs) and traumatic events. However, emerging evidence suggests that chronic discrimination also may contribute to PTSD-S. Weight-based discrimination is salient for people with obesity but has received little attention in relation to PTSD-S.

OBJECTIVE

Our study examined factors that may contribute to the link between experienced weight stigma (WS), which is common in individuals seeking bariatric surgery, and PTSD-S.

SETTING

Teaching hospital and surgical weight loss center in the United States.

METHODS

A total of 217 participants completed self-report surveys of experienced and internalized WS, ACEs, and PTSD-S. Demographics and trauma history were obtained from patient medical records. A stepwise multiple regression examined associations between experienced WS and internalized WS with PTSD-S, co-varying demographics, ACEs, and trauma, followed by examination of whether findings held co-varying anxiety/depressive symptoms in a participant subset (n = 189).

RESULTS

After accounting for covariates in step 1 and ACEs and trauma in step 2 (ΔR² = .14), experienced WS and internalized WS accounted for substantial PTSD-S variance in steps 2 and 3 (ΔR² = .12 and .13, respectively; overall model R² =.44; P < .001). Findings held after co-varying anxiety/depressive symptoms.

CONCLUSIONS

Over and above ACEs and trauma, experienced WS and internalized WS may contribute to PTSD-S. Longitudinal research is needed to better elucidate the pathways underlying these associations.

Effects of Metabolic Medicine and Metabolic Surgery on Patient-Reported Outcomes Among Patients with Type 2 Diabetes

The assessment and management of patient-reported outcomes (PROs) is considered secondary to that of cardiometabolic outcomes. When assessed, health-related quality of life (HRQOL), a PRO, can yield pertinent information that cannot be obtained from cardiometabolic assessments. For instance, physical and mental distress can be quantified and treated. Moreover, treatment convenience and satisfaction can be gaged. Behavioral modification, bariatric surgery, and pharmacotherapy can improve PROs. Typically, HRQOL is responsive to changes in weight. Specifically, weight loss and weight gain are associated with positive and negative changes in quality of life, respectively. In addition, patient satisfaction can be influenced by glycemic control. Therefore, hypoglycemia and hyperglycemic episodes can negatively affect patient satisfaction. When managing type 2 diabetes (T2D), it is important to consider how therapies impact PROs. Generally, changes in clinical outcomes mirror changes in PROs. To best manage T2D, integrating the assessment of PROs with clinical outcomes is needed.

Comparison of Sleeve Gastrectomy vs Intensive Lifestyle Modification in Patients With a BMI of 30 to Less Than 35

IMPORTANCE

There is a lack of studies evaluating sleeve gastrectomy compared with intensive lifestyle treatment in patients with class 1 obesity (body mass index [BMI] 30 to <35 [calculated as weight in kilograms divided by height in meters squared]).

OBJECTIVE

To compare outcomes and safety of sleeve gastrectomy compared with intensive nonoperative obesity treatment in patients with class 1 obesity.

DESIGN, SETTING, AND PARTICIPANTS

This matched, nationwide cohort study included patients with class 1 obesity who underwent a sleeve gastrectomy or intensive lifestyle treatment between January 1, 2012, and December 31, 2017, and who were registered in the Scandinavian Obesity Surgery Registry or the Itrim health database. Participants with class 1 obesity were matched 1:2 using a propensity score including age, sex, BMI, treatment year, education level, income, cardiovascular disease, and use of antibiotic drugs, antidepressants, and anxiolytics.

INTERVENTIONS

Sleeve gastrectomy or intensive lifestyle treatment.

MAIN OUTCOMES AND MEASURES

Outcomes included weight loss after intervention, changes in metabolic comorbidities, substance use disorders, self-harm, and major cardiovascular events retrieved from the National Patient Register, Prescribed Drug Register, and Cause of Death Register as well as the Scandinavian Obesity Surgery Registry and the Itrim health database. Data were analyzed from December 1, 2021 until May 31, 2022.

RESULTS

The study included 1216 surgery patients and 2432 lifestyle participants with similar mean (SD) BMI (32.8 [1.4] vs 32.9 [1.4]), mean (SD) age (42.4 [9.7] vs 42.6 [12.7] years), and sex (1091 [89.7%] vs 2191 [90.1%] women). Surgery patients had greater 1-year weight loss compared with controls (22.9 kg vs 11.9 kg; mean difference, 10.7 kg; 95% CI, 10.0-11.5 kg; P < .001). Over a median follow-up of 5.1 years (IQR, 3.9-6.2 years), surgery patients had a lower risk of incident use of diabetes drugs (59.7 vs 100.4 events per 10 000 person-years; hazard ratio [HR], 0.60; 95% CI, 0.39-0.92; P = .02) and greater 2-year diabetes drug remission (48.4% vs 22.0%; risk difference 26.4%; 95% CI, 11.7%-41.0%; P < .001), but higher risk for substance use disorder (94 vs 50 events per 10 000 person-years; HR, 1.86; 95% CI, 1.30-2.67; P < .001) and self-harm (45 vs 25 events per 10 000 person-years; HR, 1.81; 95% CI, 1.09-3.01; P = .02). No between-group difference in occurrence of major cardiovascular events was observed (23.4 vs 24.8 events per 10 000 person-years; HR, 0.96; 95% CI, 0.49-1.91; P = .92).

CONCLUSIONS AND RELEVANCE

In this cohort study, compared with intensive nonoperative obesity treatment, sleeve gastrectomy in patients with class 1 obesity was associated with greater weight loss, diabetes prevention, and diabetes remission but a higher incidence of substance use disorder and self-harm.

Comprehensive Review and Updates on Holistic Approach Towards Non-Alcoholic Fatty Liver Disease Management with Cardiovascular Disease

PURPOSE OF REVIEW

The global prevalence of non-alcoholic fatty liver disease (NAFLD) presents an unmet need in treating these, often asymptomatic, individuals. In this review, we summarised NAFLD management and described recent developments in non-alcoholic steatohepatitis (NASH) therapeutics that can shape the future of NAFLD.

RECENT FINDINGS

A multi-disciplinary effort in promoting sustainable lifestyle measures is paramount, with the goal of either limiting energy surplus alone or in combination with targeting downstream pathways of inflammation and fibrosis. Several antidiabetic medications like PPAR-γ agonist and glucagon-like peptide receptor agonists have beneficial effects on the metabolic profile as well as NASH histology. Vitamin E has shown promise in specific groups of patients with the haptoglobin2 allele protein. Newer drugs have demonstrated promising results in NASH resolution and fibrosis improvement such as obeticholic acid, resmetirom, aramchol, efruxifermin, aldafermin and lanifibranor. Apart from discussing the results of late stage clinical trials and the possible challenges in managing these patients with limited approved therapies, we also discussed the specific management of comorbidities (diabetes, hypertension, hyperlipidaemia, cardiovascular diseases) in NAFLD patients. Treatment strategy needs to target improvements in liver-related outcomes and cardiometabolic profile.

The Relationship Between Percentage Weight Loss and World Health Organization-Five Wellbeing Index (WHO-5) in Patients Having Bariatric Surgery

Purpose

The association between bariatric surgery outcome and depression remains controversial. Many patients with depression are not offered bariatric surgery due to concerns that they may have suboptimal outcomes. The aim of this study was to investigate the relationship between baseline World Health Organization-Five Wellbeing Index (WHO-5) and percentage total weight loss (%TWL) in patients after bariatric surgery.

Materials and Methods

All patients were routinely reviewed by the psychologist and screened with WHO-5. The consultation occurred 3.5 ± 1.6 months before bariatric surgery. Body weight was recorded before and 1 year after surgery. A total of 45 out of 71 (63.3%) patients with complete WHO-5 data were included in the study. Data analysis was carried out with IBM SPSS Statistics (version 27) to determine the correlation between baseline WHO-5 and %TWL in patients having bariatric surgery.

Results

Overall, 11 males and 34 females were involved with mean age of 47.5 ± 11.5 and BMI of 46.2 ± 5.5 kg/m². The %TWL between pre- and 1-year post-surgery was 30.0 ± 8.3% and the WHO-5 Wellbeing Index mean score was 56.5 ± 16.8. We found no correlation between %TWL and the WHO-5 Wellbeing Index (r = 0.032, p = 0.83).

Conclusion

There was no correlation between the baseline WHO-5 Wellbeing Index and %TWL 1-year post-bariatric surgery. Patients with low mood or depression need to be assessed and offered appropriate treatment but should not be excluded from bariatric surgery only based on their mood.

Graphical Abstract

Long-term complications after gastric bypass and sleeve gastrectomy: What information to give to patients and practitioners, and why?

Bariatric surgery is now recognized as the most effective treatment of morbid obesity, leading to durable weight loss and resolution of associated co-morbidities. Roux-en-Y gastric bypass and sleeve gastrectomy are the two most widely used operations today. However, potentially serious medical, surgical, and/or psychiatric complications can occur that raise questions regarding the benefits of this type of surgery. These complications can lead to surgical re-operations, iterative hospitalizations, severe nutritional deficiencies and psychological disorders. Indeed, death from suicide is said to be three times higher than in non-operated obese patients. These results are of concern, all the more because of the high prevalence of patients lost to follow-up (for various and multifactorial reasons) after bariatric surgery. However, better knowledge of post-surgical sequelae could improve the information provided to patients, the preoperative evaluation of the benefit/risk ratio, and, for patients undergoing surgery, the completeness and quality of follow-up as well as the detection and management of complications. The development of new strategies for postoperative follow-up such as telemedicine but also the mobilization of all the actors along the healthcare pathway can make inroads and warrant further study.

Can We Benefit from the Preoperative Psychometric Test with Symptom Checklist-90-Revised (SCL-90-R) to Predict Weight Loss After Sleeve Gastrectomy?

BACKGROUND

The psychological assessment is crucial before bariatric surgery. Derogatis' Symptom Checklist-90-Revised (SCL-90-R) is one of the most widely used measures of psychological symptoms and distress in both clinical and research settings. We aimed to investigate the predictive value of SCL-90-R subscale scores on postoperative excess weight loss percentage (EWLP) after laparoscopic sleeve gastrectomy (LSG).

METHODS

Patients who underwent primary LSG for morbid obesity and fully completed preoperative SCL-90-R between January 2016 and July 2019 were retrospectively examined. A multiple linear regression analysis was performed to investigate the relationship between descriptive and psychological variables associated with EWLP percentage at the 12th-month.

RESULTS

One hundred six patients who met the inclusion criteria were analyzed. The adequate weight loss (EWLP ˃ 50%) was achieved in 90% of patients after 12 months. The multiple linear regression analysis indicated that younger patients (β =  - 0.695; 95% CI - 1.056, - 0.333; p < 0.001), and patients with preoperative lower BMI (β =  - 1.524; 95% CI - 1.974, - 1.075; p < 0.001) achieved higher EWLP at 12th-month. High somatization score (β = 11.975; 95% CI 3.653, 20.296; p = 0.005) and a low Global Severity Index (GSI) score (β =  - 24.276; 95% CI - 41.457, - 7.095; p = 0.006) had a positive effect on EWLP at 12th-month.

CONCLUSIONS

Preoperative psychological testing can help predict surgical outcomes in the bariatric population. More intense lifestyle and behavioral support can be applied by targeting patients who are expected to lose less weight after surgery, and patients' weight loss potential can be increased.

The Norse Feedback in a population of patients undergoing bariatric surgery-Psychometric properties of a digital computer-adaptive questionnaire assessing mental health

The Norse Feedback (NF) is a questionnaire developed for patient-reported outcome monitoring with a clinical feedback system (PRO/CFS). As mental health is a concern after bariatric surgery, the use of the NF as part of PRO/CFS may be beneficial. The aim of this study is to test the reliability and validity of the NF in patients who have been accepted for or have undergone bariatric surgery. We performed separate robust confirmatory factor analyses (CFAs) to test the unidimensionality on 19 of the NF scales. We also performed correlation analyses on 19 of the NF scales with the Obesity-related Problems scale (OP). We included 213 patients. In the CFA analyses, three out of 12 scales with four or more items showed satisfactory psychometric properties in all goodness of fit indices (Suicidality, Need for Control and Self-Criticism). Four scales showed satisfactory psychometric properties in all indices but RMSEA (Somatic Anxiety, Substance Use, Social Safety and Cognitive Problems). Several of the scales demonstrated floor effects. In the correlation analyses, 18 of the 19 scales showed small-to-moderate correlation coefficients with the OP. Our demonstration of satisfactory psychometric properties on several important scales of the NF suggests that this tool may prove valuable in the routine follow-up of mental health in this population. However, further work is needed to innovate the NF for patients undergoing bariatric surgery.

Obesity Surgery

BACKGROUND

In 2017, the prevalence of obesity (BMI ≥= 30 kg/m2) in Germany was approximately 16%. Obesity increases an individual's risk of developing type 2 diabetes (T2DM) and arterial hypertension; it also increases overall mortality. Consequently, effective treatment is a necessity. Approximately 20 000 bariatric operations are performed in Germany each year.

METHODS

This review is based on pertinent publications retrieved by a selective search in the PubMed and Cochrane databases and on current German clinical practice guidelines.

RESULTS

The types of obesity surgery most commonly performed in Germany, Roux-en-Y gastric bypass and sleeve gastrectomy, lead to an excess weight loss of 27-69% ≥= 10 years after the procedure. In obese patients with T2DM, the diabetes remission rate ≥= 10 years after these procedures ranges from 25% to 62%. Adjusted regression analyses of data from large registries have shown that the incidence of malignancies is 33% lower in persons who have undergone obesity surgery compared to control subjects with obesity (unadjusted incidence 5.6 versus 9.0 cases per 1000 person-years). The operation can cause vitamin deficiency, surgical complications, gastroesophageal reflux, and dumping syndrome. Therefore, lifelong follow-up is necessary.

CONCLUSION

In view of an increasing number of patients undergoing bariatric surgery, it will probably not be feasible in the future for lifelong follow-up to be provided exclusively in specialized centers.

Emergence of bariatric psychiatry as a new subspecialty

Bariatric surgery is the branch of surgery aimed at helping a person with obesity lose weight. The implementation of surgical treatment of obesity is growing at an impressive rate. As expected, the expanding implementation of bariatric procedures has progressively revealed critical issues that were not evident when the number of obese patients treated with surgery was relatively small. One critical issue is the importance of mental health assessment and care of bariatric patients. The aim of this review is to provide readers with an up-to-date summary of the goals, methods, and clinical strategies of bariatric psychiatry. The aims can be grouped into three distinct categories. First, to ascertain that there are no psychiatric contraindications to safe bariatric surgery. Second, to diagnose and treat pre-surgery mental conditions that could predict poor weight loss. Third, to diagnose and treat post-surgery mental conditions associated with poor quality of life. Although bariatric psychiatry has gained the status of a new subspecialty within the field of mental health and psychopathology, many clinical questions remain unsolved. We need more long-term data on outcome measures such as quality of life, adherence to behavioral guidelines, risk of suicide, and post-surgery prevalence of psychological disturbances and mental disorders.

The Association Between Bariatric Surgery and Psychiatric Disorders: a National Cohort Study

PURPOSE

Previous studies have shown that bariatric surgery reduces the risk of cardiovascular outcomes. Less is known about the effects of bariatric surgery on psychiatric disorders. This cohort study compared the differential risk of psychiatric disorders between those who did and did not undergo bariatric surgery, from before until after the surgery.

MATERIALS AND METHODS

We used PearlDiver-Mariner, a national all-payor claims database. Patients were followed for 1 year before and after the index date and a difference-in-differences (DiD) study design was executed.

RESULTS

We included 56,661 bariatric surgery patients matched to 56,661 individuals with obesity. Among bariatric surgery patients, the risk of psychiatric was 18% 1 year before and increased to 70% 1 year after surgery. Among individuals with obesity, the risk of psychiatric disorders also increased from 1 year before to 1 year after, but by less (21% versus 46%). DiD analysis suggested that bariatric surgery was associated with a 27 percentage point differential increase in the risk of psychiatric disorders across all patients, representing a 135% relative increase. Results using 3 years as the pre- and post-periods lead to similar inferences.

CONCLUSION

Preexisting psychiatric disorders are similarly prevalent among bariatric surgery patients and individuals with obesity. The prevalence of psychiatric disorders increased over time for both groups, but to a larger extent among bariatric surgery patients. Adequate treatment for psychiatric disorders and appropriate implementation of behavioral health interventions may be needed to reduce the burden of psychiatric disorders following bariatric surgery.

Bariatric surgery and health outcomes: An umbrella analysis

BACKGROUND

There is a relative lack of data that systematically investigates the breadth and validity of the association between bariatric surgery and health-related outcomes. We aimed to evaluate the quantity, validity, and credibility of evidence regarding the association between bariatric surgery and health-related outcomes using an umbrella review of meta-analyses.

METHODS

We systematically searched PubMed, Embase, and the Web of Science databases from inception until December 2, 2021, to identify meta-analyses of observational or interventional studies that investigated the association between bariatric surgery and multiple health outcomes. We extracted the summary effect size and 95% confidence interval (CI) data. The Assessment of Multiple Systematic Reviews (AMSTAR-2) and Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) guidelines were used for methodological and evidence quality assessments, respectively.

RESULTS

Twenty-eight studies with 82 different health-related outcomes were included in this umbrella review. Beneficial effects of bariatric surgery have been observed in cancer incidence, mortality, cardiovascular risk, polycystic ovary syndrome (PCOS), anxiety symptoms, depressive symptoms, gestational diabetes mellitus, gestational hypertension, large for gestational age (LGA), macrosomia, post-term birth, risk of kidney stones, albuminuria, urinary incontinence, fecal incontinence, Barrett's esophagus, and diabetic retinopathy. However, adverse effects of bariatric surgery were observed for maternal anemia, perinatal mortality, congenital anomalies, preterm birth, neonatal intensive care unit (NICU) admission, intrauterine growth restriction, small for gestational age (SGA), fracture risk, upper limb fracture, suicide, self-harm, and alcohol use disorder (AUD).

CONCLUSIONS

Current evidence suggests that bariatric surgery improves the majority of health-related outcomes; however, caution is advised given it may increase the risk of adverse mental effects, perinatal problems, and fractures.

Self-harm hospitalization following bariatric surgery in adolescents and young adults

BACKGROUND

While bariatric surgery has demonstrated physical and psychological benefits, a risk of suicide and non-fatal self-harm has also been shown. The aim of this study was to compared the rate of hospitalization for self-harm during a three-year observational follow-up period between adolescents/young adults who underwent bariatric surgery in France in 2013-2014 and two control groups.

METHODS

All individuals aged 12-25 years old who underwent bariatric surgery in France between January 1st, 2013, and December 31st, 2014, were identified with a validated algorithm from the French national hospital database, and compared to a healthy sample of the general population matched for age and gender. Information relative to hospitalizations, including for self-harm (ICD-10 codes X60-84), were extracted i) between 2008 and the surgery, and ii) for a three-year follow-up period. A second unmatched control group with obesity but no bariatric surgery was also identified. Survival analyses with adjustments for confounding variables were used.

RESULTS

In 2013-2014, 1984 youths had bariatric surgery in France. During follow-up, 1.5% were hospitalized for self-harm vs. 0.3% for controls (p < 0.0001). After adjustment, subsequent hospitalization for self-harm was associated with bariatric surgery (HR 3.64, 95% CI 1.70-7.81), prior psychiatric disorders (HR 7.76, 95% CI 3.76-16.01), and prior self-harm (HR 4.43, 95% CI 1.75-11.24). When compared to non-operated youths with obesity, bariatric surgery was not associated with self-harm while prior mental disorders and self-harm were. Mortality reached 0.3% after surgery.

CONCLUSIONS

Bariatric surgery is associated with an increased risk of self-harm, mainly in relation to preexisting psychological conditions. Vigilance and appropriate care are thus warranted in vulnerable individuals.

Affective temperaments and obesity: Is there an association with binge eating episodes and multiple weight cycling?

BACKGROUND

affective temperaments have been so far understudied in the field of obesity. Therefore, we aimed to assess affective temperaments in outpatients with obesity reporting symptoms of binge eating (BE) and multiple weight cycling (MWC) and to investigate the likelihood of an association between affective temperaments and risk of both conditions.

METHODS

A total of 300 individuals with obesity seeking treatment at the Obesity Unit of an academic hospital were asked to complete self-report measures of affective temperaments, BE, depressive and anxiety symptoms, and quality of life.

RESULTS

Even in the absence of full-blown mental disorders, symptoms of anxiety and depression emerged in the sample; 197 individuals (65.6%) reported BE and 162 (54%) MWC. The most frequent affective temperament was the depressive one. Depression symptoms and cyclothymic scores (directly), and age and hyperthymic score (inversely) were significantly associated with BE risk, while being an active smoker (directly) and hyperthymic score (inversely) were significantly associated with MWC risk, after controlling for confounders in a multiple logistic regression.

LIMITATIONS

sample size was small, the study was limited to a single center, no formal definition of weight cycling exists and MWC was self-reported.

CONCLUSIONS

A substantial number of outpatients with obesity reported BE and MWC notwithstanding the absence of a formal psychiatric diagnosis. Cyclothymic scores were positively associated with BE while the hyperthymic temperament showed a protective effect on both BE and MWC. These findings suggest the need for multidisciplinary treatments for people with obesity enhancing research on temperament-based psychological interventions.

Associations among psychopathology and eating disorder symptoms and behaviors in post-bariatric surgery patients

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.

Metabolic surgery in treatment of obese Japanese patients with type 2 diabetes: a joint consensus statement from the Japanese Society for Treatment of Obesity, the Japan Diabetes Society, and the Japan Society for the Study of Obesity

Bariatric surgery has been shown to have a variety of metabolically beneficial effects for patients with type 2 diabetes (T2D), and is now also called metabolic surgery. At the 2nd Diabetes Surgery Summit held in 2015 in London, the indication for bariatric and metabolic surgery was included in the “algorithm for patients with type T2D”. With this background, the Japanese Society for Treatment of Obesity (JSTO), the Japan Diabetes Society (JDS) and the Japan Society for the Study of Obesity (JASSO) have formed a joint committee to develop a consensus statement regarding bariatric and metabolic surgery for the treatment of Japanese patients with T2D. Eventually, the consensus statement was announced at the joint meeting of the 38th Annual Meeting of JSTO and the 41st Annual Meeting of JASSO convened in Toyama on March 21, 2021. In preparing the consensus statement, we used Japanese data as much as possible as scientific evidence to consider the indication criteria, and set two types of recommendation grades, “recommendation” and “consideration”, for items for which recommendations are possible. We hope that this statement will be helpful in providing evidence-based high-quality care through bariatric and metabolic surgery for the treatment of obese Japanese patients with T2D.

Expert opinion on the preoperative medical optimization of adults with diabetes undergoing metabolic surgery

Diabetes mellitus (DM) and obesity are interrelated in a complex manner, and their coexistence predisposes patients to a plethora of medical problems. Metabolic surgery has evolved as a promising therapeutic option for both conditions. It is recommended that patients, particularly those of Asian origin, maintain a lower body mass index threshold in the presence of uncontrolled DM. However, several comorbidities often accompany these chronic diseases and need to be addressed for successful surgical outcome. Laparoscopic Roux-en-Y gastric bypass (RYGB) and laparoscopic sleeve gastrectomy (LSG) are the most commonly used bariatric procedures worldwide. The bariatric benefits of RYGB and LSG are similar, but emerging evidence indicates that RYGB is more effective than LSG in improving glycemic control and induces higher rates of long-term DM remission. Several scoring systems have been formulated that are utilized to predict the chances of remission. A glycemic target of glycated hemoglobin < 7% is a reasonable goal before surgery. Cardiovascular, pulmonary, gastrointestinal, hepatic, renal, endocrine, nutritional, and psychological optimization of surgical candidates improves perioperative and long-term outcomes. Various guidelines for preoperative care of individuals with obesity have been formulated, but very few specifically focus on the concerns arising from the presence of concomitant DM. It is hoped that this statement will lead to the standardization of presurgical management of individuals with DM undergoing metabolic surgery.
