Psychological Benefits of a Preoperative Educational Bridging Program for Bariatric Surgery: Does Face-to-Face versus Videoconference-based delivery make a difference?

INTRODUCTION: Short educational programs prior to metabolic and bariatric surgery (MBS) provide information to prepare patients adequately for surgery and subsequent changes. Our knowledge of the beneficial effects of these programs on stabilizing and improving mental health of patients with obesity awaiting surgery is incomplete. The objective of this study was to assess the effects of a group-based educational program before MBS on three key factors: i) patients' mental health, ii) the program's perceived helpfulness from the patients' perspective, and iii) the effectiveness of delivering the program online via videoconferencing. METHODS: Validated questionnaires for anxiety, depression, stress, and quality of life before and after the program were assessed. Additionally, participants' perspectives of benefits were assessed. Two subgroups, one participating in face-to-face classes, the other participating online via videoconferencing, were compared. RESULTS: Three hundred five patients with obesity waiting for MBS participated in the program. The dropout rate was 3%. On mean average, symptoms of anxiety (-1.1 units (SD 4.6), p < 0.001), depression (-0.9 units (SD 4.6), p < 0.001), and stress (-4.6 units (SD 15.6), p < 0.001) improved, while physical quality of life (+1.7 (SD 9.7), p = 0.016) and body weight (-0.3 kg (SD 8.7), p = 0.57) remained stable. Patients perceived the program as very beneficial. The results were similar between delivery methods (face-to-face versus videoconferencing). CONCLUSION: The educational program proved to be effective in bridging the gap in preoperative preparation while also stabilizing participants' mental health. In addition, participants perceived the program as supportive. Online participation via video conferencing can be offered as an equivalent option to face-to-face classes.

Conventional weight loss therapy in morbid obesity during COVID-19 pandemic: degree of burdens at baseline and treatment efficacy.

Introduction: COVID-19 affected global physical and psychological health. The purpose of this study was to explore the pandemics impact on health-related quality of life (HRQoL), mental health (anxiety, depression, and perceived stress) and eating behavior in people with severe obesity participating in a multimodal conservative behavioral weight loss (BWL) program conducted via videoconferencing. Additionally, the efficacy of the six-month BWL program in a virtual video-based setting during the pandemic was examined. Methods: 297 participants of a face-to-face multimodal behavioral weight loss program prior to the pandemic (PrePAN, May 2014-September 2019) and 146 participants of the in terms of content same intervention in a videoconference-based setting during the pandemic (PAN, July 2020-April 2022) were questioned and compared using standardized questionnaires for HRQoL, symptoms of depressive and anxiety disorders, perceived stress, and eating behavior at baseline and at the end of treatment. Results: Symptoms for anxiety, depression and perceived stress were similar between PrePAN and PAN at baseline. In addition, PAN tended to show lower disinhibition of eating behavior and feelings of hunger than PrePAN. During the pandemic, the BWL intervention resulted in body weight loss (67%) or stabilization (16%) in most of the participants. It also contributed by improving physical HRQoL, lower worries, and improved eating behaviors compared to baseline. Conclusion: During the COVID-19 pandemic, baseline mental health of people with morbid obesity was not worse than before the pandemic. Additionally, the BWL intervention in the virtual video-based setting stabilized and improved physical and mental health during the COVID-19 pandemic.

Mental Health Variables Impact Weight Loss, Especially in Patients with Obesity and Binge Eating: A Mediation Model on the Role of Eating Disorder Pathology.

BACKGROUND: Various mental health and eating behavior variables have been independently associated with predicting weight loss in individuals with obesity. This study aims to investigate a mediation model that assesses the distinct contributions of these variables in predicting weight changes in patients with obesity following an outpatient behavioral weight loss intervention (BWLI). METHODS: General mental health (depression, anxiety, stress, impulsivity), eating behavior (cognitive restraint, disinhibition, hunger), eating disorder pathology, and body mass index (BMI) were assessed in a group of 297 patients with obesity at the admission of a BWLI program. BMI was re-evaluated during the final treatment session. A mediation model was employed to examine whether mental health and eating behavior variables predicted BMI changes, with eating disorder pathology serving as a mediator. The model was tested both overall and within two patient subgroups: those with regular binge eating (≥four episodes/month) and those without. RESULTS: In the overall sample (n = 238), the relationships between depression, impulsivity, and cognitive restraint with BMI change were mediated by eating disorder pathology. In the subgroup with regular binge eating (n = 99, 41.6%), the associations between stress and disinhibition with BMI change were additionally mediated by eating disorder pathology. In the subgroup without regular binge eating, eating disorder pathology showed no mediating effect. DISCUSSION: Multiple mental health and eating behavior variables assessed at admission predicted BMI changes, particularly when mediated by eating disorder pathology in patients with regular binge eating. A comprehensive psychopathological assessment prior to starting BWLI may help identify multiple factors affecting prognosis and treatment outcomes. Long-term follow-up studies in this field are required.

Attitude Matters! How Attitude towards Bariatric Surgery Influences the Effects of Behavioural Weight Loss Treatment.

INTRODUCTION: Multidisciplinary obesity services at university hospitals usually treat patients with more complex and severe obesity. In addition, patients with Class 3 obesity, in particular, have different attitudes regarding the choices of therapy. METHODS: This explorative study investigated the effect of patient attitudes towards bariatric surgery on body weight change (primary outcome) and psychological improvement (secondary outcomes: quality of life, depression, anxiety, and eating behaviour) in a 6-month moderate behavioural weight loss (BWL) programme in a university outpatient setting. RESULTS: 297 patients with mostly Class 3 obesity participated in the programme. The patients did not yet have any indications for bariatric surgery. Of the participants, 37% had a positive attitude towards bariatric surgery (POS), whereas 38% had a negative attitude (NEG). The drop-out rate was 8%. NEG participants lost significantly more body weight than the POS participants (intention-to-treat population: 4.5 [SD: 6.3] kg versus 0.4 [SD: 5.8] kg; p < 0.001). In both subgroups, anxiety, depression, the mental score for quality of life, and eating behaviour improved. CONCLUSION: A BWL treatment in a clinical setting identified 2 distinct groups with different attitudes towards bariatric surgery that were associated with different body weight change outcomes. These groups may require differently targeted programmes to achieve the best body weight loss results.

Conventional weight loss interventions across the different BMI obesity classes: A systematic review and quantitative comparative analysis.

OBJECTIVE: The recommendation for conventional body weight loss (BWL) treatment in obesity is 5-10%. It is not clear whether BWL is similar across the three different body mass index (BMI) obesity classes. The aim was to provide an overview on BWL across these classes in moderate lifestyle/diet intervention programs. METHOD: A systematic literature search was conducted and the evidence of randomized controlled trials (RCTs) and pre-post design studies synthesized. The outcome was BWL. RESULTS: For RCTs, mean BWL in the intervention group was 3.6 kg (class I) and 5.3 kg (class II), which equates to 4 and 5% BWL, respectively. None of the assessed class III obesity studies met the inclusion criteria. For pre-post design studies, mean BWL was 5.4 kg (class I), 5.5 kg (class II) and 7.9 kg (class III), with high variation within and across studies in the latter. This equates to 6, 5 and, 6% BWL, respectively. CONCLUSIONS: BWL of moderate BWL programs are similar across the different obesity classes. For class I obesity, the results differ between RCT and pre-post design studies by 2% BWL. The high variation of BWL in class III obesity might reflect different states of motivation such as the attitude towards bariatric surgery.

Expression and activity of P-glycoprotein (MDR1/ABCB1) in peripheral blood mononuclear cells from patients with anorexia nervosa compared with healthy controls.

OBJECTIVE: Pharmacotherapeutic strategies for treatment of anorexia nervosa (AN) are characterized by limited success. Some drugs used (antipsychotics, selective serotonin reuptake inhibitors) are transported by P-glycoprotein (P-gp), a transporter with major impact on pharmacokinetics of substrate drugs. Biochemical alterations seen in AN patients could lead to increased expression and/or activity of P-gp and therefore to diminished access of drugs to the brain. The aim of our study was to investigate expression and activity levels of P-gp in peripheral blood mononuclear cells (PBMCs) in AN patients. METHOD: PBMCs of 16 AN patients and 16 controls were isolated. Activity of P-gp was determined by flow cytometry and expression was quantified by reverse-transcriptase-real-time-polymerase-chain-reaction. RESULTS: Neither a significant difference in P-gp expression (AN: 0.00154 +/- 0.00088 [MDR1/beta2 mg], control: 0.00244 +/- 0.0013 [MDR1/beta2 mg], p = .138) nor a difference in P-gp activity (rhodamine 123 ratio AN: 1.79 +/- 0.73, control: 2.03 +/- 0.42, p = .20) between AN patients and healthy controls could be detected. In contrast to previous studies, expression and activity of P-gp correlated significantly (p = .0031). CONCLUSION: Failure in pharmacotherapy with P-gp substrates in AN patients are probably neither caused by different P-gp expression nor activity levels.

Central venous catheter complications during home parenteral nutrition: a prospective pilot study of 481 patients with more than 30,000 catheter days.

BACKGROUND: Home parenteral nutrition (HPN) has been shown to delay deterioration in cancer patients with malnutrition. Its risk-benefit ratio, however, is determined by the threat of central venous catheter (CVC) complications. Only few prospective studies on this subject exist, most of them based on small samples. The objective of this study was to provide reliable estimates of incidence rates of CVC complications in everyday HPN patient care in Germany. PATIENTS AND METHODS: Aiming for a large prospective cohort study, we cooperated with a service provider caring for HPN patients nationwide. Between July 1 and November 30, 2006, all consecutive adult patients with more than 10 infusion days and no previous history of HPN were recruited. Follow-up ended on January 31, 2007. Data were collected in a standardised way by the provider's staff. To prevent underreporting, we used computer-assisted telephone interviews with medical caregivers as a provider-independent data source. RESULTS: 481 patients met the inclusion criteria, contributing a total of 31,337 catheter days. 52 patients experienced a total of 63 CVC complications, resulting in an incidence rate of 2.01 CVC complications per 1,000 catheter days including 1.02 CVC infections per 1,000 catheter days. CONCLUSION: HPN administration can be safely performed with a relatively low rate of CVC complications.

Treatment outcome in people with subthreshold compared with full-syndrome binge eating disorder.

OBJECTIVE: There is a controversial discussion in the literature as to whether individuals with subthreshold binge eating disorder (subBED) differ clinically significantly from individuals with full-syndrome binge eating disorder (BED). This study was designed to compare eating-related and general psychopathology at baseline and in response to a multimodal treatment program in obese people with subBED compared with BED. RESEARCH METHODS AND PROCEDURES: A total of 96 obese participants (BMI > or = 30 kg/m(2)) were assessed for eating-related and general psychopathology at baseline. Thirty-nine participants meeting criteria for BED and 19 participants meeting criteria for subBED attended a 15-session outpatient group therapy including cognitive behavioral therapy extended by interpersonal therapy, nutritional counseling, and a supervised walking exercise. Participants with eating disorders were reassessed at the end of treatment and at 3-month follow-up. The obese control group without an eating disorder (n = 38) was assessed once. This was not a randomized controlled trial. RESULTS: Intent-to-treat analyses revealed no differences between subBED and full-syndrome BED participants with regard to eating-related and general psychopathology at baseline and with regard to treatment outcome. All participants experienced substantial improvements, and the results remained stable during follow-up (except for dietary restraint). At follow-up, participants with subBED and BED remained different from non-eating disorder controls in eating-related but not general psychopathology. DISCUSSION: The findings indicate that our multimodal treatment program is equally effective in obese subBED and BED participants, suggesting that a differentiation currently seems not to be of clinical significance.
