Body Image Disturbances and Weight Bias After Obesity Surgery: Semantic and Visual Evaluation in a Controlled Study, Findings from the BodyTalk Project.

PURPOSE: Body image has a significant impact on the outcome of obesity surgery. This study aims to perform a semantic evaluation of body shapes in obesity surgery patients and a group of controls. MATERIALS AND METHODS: Thirty-four obesity surgery (OS) subjects, stable after weight loss (average 48.03 ± 18.60 kg), and 35 overweight/obese controls (MC), were enrolled in this study. Body dissatisfaction, self-esteem, and body perception were evaluated with self-reported tests, and semantic evaluation of body shapes was performed with three specific tasks constructed with realistic human body stimuli. RESULTS: The OS showed a more positive body image compared to HC (p < 0.001), higher levels of depression (p < 0.019), and lower self-esteem (p < 0.000). OS patients and HC showed no difference in weight bias, but OS used a higher BMI than HC in the visualization of positive adjectives (p = 0.011). Both groups showed a mental underestimation of their body shapes. CONCLUSION: OS patients are more psychologically burdened and have more difficulties in judging their bodies than overweight/obese peers. Their mental body representations seem not to be linked to their own BMI. Our findings provide helpful insight for the design of specific interventions in body image in obese and overweight people, as well as in OS.

Weight bias and linguistic body representation in anorexia nervosa: Findings from the BodyTalk project.

OBJECTIVE: This study provides a comprehensive assessment of own body representation and linguistic representation of bodies in general in women with typical and atypical anorexia nervosa (AN). METHODS: In a series of desktop experiments, participants rated a set of adjectives according to their match with a series of computer generated bodies varying in body mass index, and generated prototypic body shapes for the same set of adjectives. We analysed how body mass index of the bodies was associated with positive or negative valence of the adjectives in the different groups. Further, body image and own body perception were assessed. RESULTS: In a German-Italian sample comprising 39 women with AN, 20 women with atypical AN and 40 age matched control participants, we observed effects indicative of weight stigmatization, but no significant differences between the groups. Generally, positive adjectives were associated with lean bodies, whereas negative adjectives were associated with obese bodies. DISCUSSION: Our observations suggest that patients with both typical and atypical AN affectively and visually represent body descriptions not differently from healthy women. We conclude that overvaluation of low body weight and fear of weight gain cannot be explained by generally distorted perception or cognition, but require individual consideration.

A Systematic Review of the Effect of Neurofeedback in Cancer Patients.

INTRODUCTION: Neurofeedback (NF) or electroencephalogram (EEG)-Biofeedback is a drug-free form of brain training to directly alter the underlying neural mechanisms of cognition and behavior. It is a technique that measures a subject's EEG signal, processes it in real time, with the goal to enable a behavioral modification by modulating brain activity. The most common application of the NF technology is in epilepsies, migraine, attention-deficit/hyperactivity disorder, autism spectrum disorder, affective disorders, and psychotic disorders. Few studies have investigated the use of NF in context of psychosomatic illnesses. Little is known about the use in cancer patients or postcancer survivors despite the high number of this patient group. OBJECTIVES: We here provide a systematic review of the use and effect of NF on symptoms and burden in cancer patients and long-term cancer survivors. METHODS: In conducting this systematic review, we followed the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) Statement. RESULTS: Our search resulted in only 3 experimental studies, 1 observational study, and 2 case reports. Given the heterogeneity of the intervention systems and protocols, no meta-analysis was conducted. CONCLUSION: Altogether, there is initial evidence that NF is a complementary, drug-free, and noninvasive therapy that has the potential to ameliorate symptoms in this patient group, such as pain, fatigue, depression, and sleep. Further studies are highly needed.

Psychosocial predictors for outcome after total joint arthroplasty: a prospective comparison of hip and knee arthroplasty.

BACKGROUND: As findings regarding predictors for good outcome after total joint arthroplasty are highly inconsistent, aim of this study was to investigate the influence of the psychosocial variables sense of coherence and social support as well as mental distress on physical outcome after surgery. It should be investigated if different predictors are important in patients after total hip arthroplasty (THA) compared to patients after total knee arthroplasty (TKA). METHODS: In a prospective design, 44 patients undergoing THA and 61 patients undergoing TKA were examined presurgery and 6 and 12 weeks after surgery using WOMAC (disease-specific outcome), SF-36 (health-related quality of life), BSI (psychological distress), SOC-13 (sense of coherence), and F-SozU (social support). Changes over time were calculated by analyses of variance with repeated measures. Stepwise multiple linear regression analyses were computed for each group to predict scores of WOMAC total and all WOMAC subscales 12 weeks postoperatively. RESULTS: THA as well as TKA patients experienced improvements in all parameters (effect sizes for WOMAC scores between η2 = .387 and η2 = .631) with THA patients showing even better results than TKA patients. WOMAC scores 12 weeks after surgery were predicted predominantly by WOMAC baseline scores in TKA with an amount of explained variance between 9.6 and 19.5%. In THA, 12-weeks WOMAC scores were predicted by baseline measures of psychosocial aspects (anxiety, sense of coherence, social support). In this group, predictors accounted for 17.1 to 31.6% of the variance. CONCLUSIONS: Different predictors for outcome after total joint arthroplasty were obtained for THA and TKA patients. Although psychosocial aspects seemed to be less important in TKA patients, preoperatively, distressed patients of both groups should be offered interventions to reduce psychological distress to obtain better outcomes after surgery.

Feasibility and Acceptability of an Alcohol Addiction Therapy Integrated in a Transplant Center for Patients Awaiting Liver Transplantation.

AIMS: To evaluate the feasibility and acceptability of an addiction program within the setting of liver transplantation, with classification of behavior change techniques used to reduce excessive drinking. METHOD: Patients with alcohol-related liver disease (N = 100) participated in a manualized addiction group therapy over 12 sessions, pre-transplantation. Relapses were identified by measurement of urinary ethyl glucuronide (EtG). RESULTS: Two groups were identified according to the frequency of participation: completers (n = 42) vs. drop-outs (n = 58). A total of 16.5% of the samples of completers in comparison to 30.5% of the samples of drop-outs tested positive for EtG (P < 0.001). CONCLUSIONS: The results suggest that implementation of an addiction therapy program during the waiting time might help to limit the frequency of drinking. These patients appeared often to under-report their alcohol consumption; including a biomarker such as urinary EtG in such settings is recommended.

Self-reports on symptoms of alcohol abuse: liver transplant patients versus rehabilitation therapy patients.

Context-Self-report measures often underestimate the severity of symptoms of alcohol abuse. It is generally supposed that patients who abuse alcohol tend to minimize their drinking behavior. However, the validity of self-reports also can be influenced by external factors such as the setting. Objective-To investigate how the setting influences self-reporting on symptoms of alcohol abuse in patients with alcoholic liver disease. Design, Setting and Participants-Cross-sectional study in patients before liver transplant (n = 40) and patients in rehabilitation therapy (n = 44). Main Outcome Measure-Scores on the Munich Alcoholism Test, which consists of a self-report-scale and an expert-rating scale. Results-The discrepancy in scores on the self-report scale and the expert-rating scale differed significantly between patients before liver transplant and patients in rehabilitation therapy. Furthermore, patients in the rehabilitation therapy group reported higher alcoholism scores on the self-report questionnaire than did patients before liver transplant, but the groups did not differ in the expert evaluation value. Conclusion-The transplant setting seems to evoke minimizing in self-reports in patients with alcohol abuse. Minimizing or denying symptoms of alcohol abuse does not seem to be a specific characteristic of persons with alcohol abuse, as it is also caused by the circumstances. In the transplant setting, more attention should be given to the psychologically difficult situation for patients with potential alcohol abuse. Implementation of psychoeducational interventions in the treatment process before transplant could be a first step toward reaching this goal.

[Validation of the Essen Quality of Life-Index for Eating Disorders (ELI)]. / Validierung des Essener Lebensqualitäts-Index für Essstörungen (ELI).

The aim of this study was the validation of a short disease-specific questionnaire (ELI, Essen Quality of Life Index for Eating Disorders) to measure the health-related quality of life in patients with eating disorders. A total of 182 currently ill and former eating disordered patients and 87 healthy controls completed the ELI questionnaire as well as other reliable and valid instruments (EDQOL, SF-12, EDI-2, FKB-20, SEED, BSI, IIP-D and SOC-13). In addition, 46 eating disorder patients completed the same questionnaires at the end of therapy. The ELI proved to have a high internal consistency of α=0.96. As expected, one main factor was found with a high declaration of variance of 71.25%. There is also evidence for very good construct validity and good sensitivity for change. Therefore, the ELI is an economic, reliable and valid instrument that assesses disease-specific health-related quality of life of individuals with eating disorders. The questionnaire can be recommended for research as well as clinical care contexts.

Non-invasive separation of alcoholic and non-alcoholic liver disease with predictive modeling.

BACKGROUND & OBJECTIVE: Currently, a major clinical challenge is to distinguish between chronic liver disease caused by metabolic syndrome (non-alcoholic fatty liver disease, NAFLD) from that caused by long term or excessive alcohol consumption (ALD). The etiology of severe liver disease affects treatment options and priorities for liver transplantation and organ allocation. Thus we compared physiologically similar NAFLD and ALD patients to detect biochemical differences for improved separation of these mechanistically overlapping etiologies. METHODS: In a cohort of 31 NAFLD patients with BMI below 30 and a cohort of ALD patient with (ALDC n = 51) or without cirrhosis (ALDNC n = 51) serum transaminases, cell death markers and (adipo-)cytokines were assessed. Groups were compared with One-way ANOVA and Tukey's correction. Predictive models were built by machine learning techniques. RESULTS: NAFLD, ALDNC or ALDC patients did not differ in demographic parameters. The ratio of alanine aminotransferase/aspartate aminotransferase--common serum parameters for liver damage--was significantly higher in the NAFLD group compared to both ALD groups (each p<0.0001). Adiponectin and tumor necrosis factor(TNF)-alpha were significantly lower in NAFLD than in ALDNC (p<0.05) or ALDC patients (p<0.0001). Significantly higher serum concentrations of cell death markers, hyaluronic acid, adiponectin, and TNF-alpha (each p<0.0001) were found in ALDC compared to ALDNC. Using machine learning techniques we were able to discern NAFLD and ALDNC (up to an AUC of 0.9118±0.0056) or ALDC and ALDNC (up to an AUC of 0.9846±0.0018), respectively. CONCLUSIONS: Machine learning techniques relying on ALT/AST ratio, adipokines and cytokines distinguish NAFLD and ALD. In addition, severity of ALD may be non-invasively diagnosed via serum cytokine concentrations.

Anxiety, posttraumatic stress, and fear of cancer progression in patients with melanoma in cancer aftercare.

UNLABELLED: Several studies have described mental distress and anxiety in patients with melanoma. The findings of these studies varied from patients with a quality of life similar to the general population and those with increased mental distress. In the present study, we investigated anxiety, posttraumatic stress, and fear of cancer progression to gain a detailed picture of the burdens of these patients. PATIENTS AND METHODS: 70 patients with malignant melanoma who attended cancer aftercare were surveyed using the psychometric instruments Hospital Anxiety and Depression Scale (HADS), Posttraumatic Symptom Scale (PTSS-10), and Fear of Progression Questionnaire (FoP-Q). The questionnaires were evaluated and an analysis of the single items carried out. RESULTS: The scores for the three anxiety parameters were low, but 7% of the patients presented an increased HADS score, and 17% an increased PTSS-10 value. An analysis of the items showed that patients feared physical disabilities more than mental distress or lack of social support. CONCLUSION: Most of the patients perceived themselves as stable, and relied on the assistance of their families. However, a small group of patients suffered from clinically relevant anxiety; these patients should be given the support indicated for their specific distress.
