RESUMO
OBJECTIVES: The immediate living environment might, like other lifestyle factors, be significantly related to mental well-being. The current study addresses the question whether five relevant subjective home environment variables (i.e., protection from disturbing nightlight, daylight entering the home, safety at home, quality of window views, and noise disturbance) are associated with levels of self-reported depression over and above well-known sociodemographic and common lifestyle variables. METHODS: Data from the Hamburg City Health Study (HCHS) were analyzed. In N = 8757 with available PHQ-9 depression data, multiple linear regression models were computed, with demographic data, lifestyle variables, and variables describing the subjective evaluation of the home environment. RESULTS: The model explained 15% of variance in depression levels, with ratings for the subjective evaluation of home environment accounting for 6%. Better protection from disturbing light at night, more daylight entering the home, feeling safer, and perceived quality of the window views, were all significantly associated with lower, while more annoyance by noise was associated with higher levels of self-reported depression. Results did not differ if examining a sample of the youngest (middle-aged participants: 46-50 years) versus oldest (70-78 years) participants within HCHS. CONCLUSION: Beyond studying the role of lifestyle factors related to self-reported depression, people's homes may be important for subclinical levels of depression in middle and older age, albeit the direction of effects or causality cannot be inferred from the present study. The development of a consensus and tools for a standardized home environment assessment is needed.

OBJECTIVES: Postoperative delirium (POD) remains the most common complication in older adults, with cognitive impairment being the main risk factor. Patients with mild cognitive impairment, in particular, have much to lose from delirium; despite this, their cognitive impairment might be clinically overlooked. Understanding which cognitive domains are particularly predictive in this regard may improve the sensitivity of preoperative testing and allow for a more targeted application of resource-intensive measures to prevent delirium in the perioperative period. The authors conducted this study with the aim of identifying the most indicative cognitive domains. DESIGN: A secondary analysis of a randomized controlled trial. SETTING: At a single center, the University Medical Centre Hamburg in Hamburg, Germany. PARTICIPANTS: Patients ≥60 years without major neurocognitive disorders (dementia, Mini-Mental State Examination score ≤23) scheduled for cardiovascular surgery. MEASUREMENTS AND MAIN RESULTS: Preoperative neuropsychologic testing and delirium screening were performed twice daily until postoperative day 5. A multiple logistic regression model was applied to determine the predictive ability of test performances for the development of delirium. RESULTS: A total of 541 patients were included in the analysis; the delirium rate was 15.6%. After controlling for confounders, only low performance within the Trail Making Test B/A (odds ratio [OR] = 1.32; 95% CI: 1.05-1.66) and letter fluency (OR = 0.66; 95% CI: 0.45-0.96) predicted a particularly high risk for delirium development. The discriminative ability of the final multiple logistic regression model to predict POD had an area under the curve of 0.786. CONCLUSIONS: Impairment in the cognitive domains of executive function and language skills associated with memory, inhibition, and access speed seem to be particularly associated with the development of delirium after surgery in adults ≥65 years of age without apparent preoperative neurocognitive impairment.

Study aims were to (I) transfer the measurement of the approach bias (Apb) related to alcoholic stimuli via the Approach Avoidance Task (AAT) into Virtual Reality (VR), (II) check whether measuring Apb in VR leads to similar or different results compared to the classical PC-based version, (III) check the validity of VR versus PC-based bias scores in terms of relatedness to clinical variables. Different 'grasping-conditions' were tested and contrasted in VR concerning (Ia) feasibility (performance): (1) never grasp, (2) always grasp, (3) grasp when PULLing stimuli towards oneself. (Ib) Differences in the bias scores between patients with alcohol use disorder (AUD) and healthy controls (HC) were examined for each grasping-condition. (II) PC-based bias scores were computed and contrasted for AUD versus HC. (III) Correlations of the different VR- versus PC-based bias scores with AUD symptom severity and impulsivity were checked to evaluate validity. (Ia) Grasping-condition 1, followed by 3, showed acceptable (> 50%) and good (> 80%) rates of correct performances allowing for robust median estimation. (Ib) Significant differences in the resulting bias scores emerged between AUD and HC only for grasping-condition 1 (p = 0.034) and 3 at trend-level (p = 0.093). For grasping-condition 1 the Apb Median for AUD was different from zero at a non-significant trend-level (p = 0.064). (II) The PC-based bias scores did not discriminate between AUD versus HC groups. (III) Grasping-condition 1 and 3 VR-based bias scores correlated significantly with impulsivity. In sum, transferring the AAT into VR is feasible, valid, and best implemented without an additional grasping-component when using the VR-controller. This way of Apb assessment represents a viable, perhaps even superior, alternative to PC-based assessments. Trial registration The trial was pre-registered at AsPredicted #76854: 'Transferring the approach avoidance task into virtual reality', 10/13/2021; prior to any analyses being undertaken.
RESUMO
BACKGROUND: Animal studies have shown beneficial effects of probiotic supplementation on the hippocampus (HC) and cognitive performance. Evidence in humans is scarce. It was hypothesised that probiotic supplementation is associated with enhanced hippocampal (HC) regional grey matter volume (rGMV), as well as HC functional connectivity (FC). Relatedly improvements in mnestic and navigational performance, or emotional well-being, were expected to be observed in healthy human volunteers. METHODS: A randomised-controlled, double-blind trial (RCT) was conducted in N = 59 volunteers (age Mean = 27.1, s.d. = 6.7), applying a multi-strain probiotic (Vivomixx®) v. non-probiotic milk-powder placebo, each with 4.4 g/day, for 4 weeks. Volumetric data was extracted from 3T structural magnetic resonance images of total HC and -subfields. Voxel-based morphometry (VBM) and FreeSurfer-based analyses were performed. Potential neuroplastic change beyond HC was explored using whole-brain-VBM for white- and GMV. Seed-based FC was calculated based on HC. Cognitive tests included visual, map-based, object-location, and verbal memory, and spatial navigation. Mental health status (stress, anxiety, depression, and emotion-regulation) was assessed using self-reports. RESULTS: There were no changes in HC-total, -subfield GMV, or FC, through probiotics. VBM revealed no changes at a whole-brain-level. There were no effects on cognitive performance or mental health. Evidence in favor of the null-hypothesis, using Bayesian statistics, was consistent. CONCLUSIONS: The applied multi-strain probiotic did not elicit any effects concerning hippocampal structural plasticity, cognition, or mental well-being in young, healthy adults. For future studies, longer application/observation RCTs, perhaps in stressed, otherwise psychologically/ cognitively vulnerable, or ageing groups, with well-founded strain selection and investigation of mechanism, are advised.
RESUMO
PURPOSE: No study has investigated the ongoing risk of substance use disorders involving illicit drugs (ISUD) after first eating disorder (ED) and whether the pattern of risk differs according to types of ED and ISUD. Therefore, we aimed to longitudinally assess the risk of a subsequent diagnosis of any ISUD (pooled category) and specific ISUD after a first-time diagnosis of anorexia nervosa (AN), bulimia nervosa (BN), or unspecified ED (USED). METHODS: A retrospective cohort study using data from Danish nationwide registers identified 20,759 ED patients and 83,038 matched controls (1:4 ratio). Risk of any ISUD diagnosis after first ED diagnosis was estimated by generating hazard ratios (HR). Logistic regression was applied to assess associations between each ED and specific ISUD. RESULTS: Patients with AN, BN, and USED (without a prior ISUD diagnosis) exhibited an increased relative risk of a subsequent diagnosis of any ISUD compared with respective controls, and the elevated risk persisted over 10 years (AN, adjusted HRs ranging from 1.60 [99% CI 1.15-2.24] to 5.16 [3.14-8.47]; BN, 2.35 [1.46-3.79] to 14.24 [6.88-29.47]; USED, 2.86 [1.35-3.79] to 8.56 [3.31-29.47]). The highest estimates were observed during the first year of follow-up. Each ED type was associated with an increased likelihood of all types of ISUD. AN and USED were most strongly associated with sedatives/hypnotics, BN with other illegal substances (e.g., ecstasy and hallucinogens). CONCLUSIONS: ED patients have a considerable risk for subsequent ISUD. Prevention efforts and treatment targeting ISUD are likely required to improve ED treatment prognosis.

BACKGROUND: The approach-avoidance training program (AATP) has shown preliminary promise as an add-on to standard treatment for alcohol dependence. However, knowledge is lacking as to whether the effectiveness of AATP can be enhanced further when performed in a typical drinking situation. The main aim of this study is to investigate whether approach-avoidance training implemented in a virtual reality bar environment is superior to the classical joystick PC-version of the AATP. METHODS: The study will be implemented as a randomized controlled trial. A total of 204consecutively enrolled alcohol use disorder (AUD) patients, recruited from alcohol inpatient clinics in Germany, Poland and Denmark, will be randomized into one of three groups at the start of standard alcohol treatment: group A) stimuli-relevant AATP + treatment as usual (TAU); group B) stimuli-relevant AATP in virtual reality + TAU, and group C) TAU only (control group). Treatment outcomes will be assessed at pre-treatment, post-treatment and 3-month follow-up. Repeated-measures ANOVA will be applied to compare the trajectories of the groups over time on drinking, craving and impulsiveness outcomes. It is hypothesized that the two experimental groups will achieve better treatment outcomes compared to group C and that group B will achieve better outcomes than group A. DISCUSSION: This study is the first trial examining the effectiveness of stimuli-relevant AATP delivered in a VR environment. The use of VR has shown promise in enhancing the effectiveness of other psychological treatments and since AATP has already been shown effective as add-on treatment, it is of interest to investigate whether these effects can be further enhanced by implementing the program in more ecologically valid environments. If proven effective, the AATP-VR can, like the AATP, be implemented easily and cheaply as add-on treatment or continued care to enhance the effectiveness of current evidence-based treatment. TRIAL REGISTRATION: ClinicalTrials.gov ID: NCT04283305 Registration date: 24.02.20.

OBJECTIVES: Smoking is a highly prevalent addictive behavior with severe and life-shortening health consequences. This is the first study to evaluate the efficacy of a newly developed imaginal variant of approach bias modification (ABM) (i.e., imaginal retraining) for the reduction of craving for tobacco and actual smoking behavior. METHODS: We randomized 345 smokers to imaginal retraining (self-help manual) or a control group (either active control or wait-list control). Assessments were carried out online. The treatment interval was 6 weeks. Craving for tobacco represented the primary outcome. The study was registered as DRKS00016860. RESULTS: Retention was 79.7% with no difference between groups. The intention-to-treat (ITT) analyses were significant for the primary outcome (Visual Analogue Scale on craving for tobacco) as well as subjective reduction of smoking (45.5 vs. 26.4%) in favor of imaginal retraining. In the treatment group, 47.6% performed the exercises at least once. This subgroup (per-protocol [PP] sample) showed a significant reduction in tobacco dependency as measured with the Cigarette Dependence Scale (short and long forms) and the Fagerström Test for Nicotine Dependence relative to controls. Number of daily cigarettes declined to a greater extent in imaginal retraining in the PP but not ITT analysis. A small dose-effect relationship emerged between craving and frequency of performance of the technique. CONCLUSION: When used regularly, imaginal retraining may reduce craving for tobacco and actual smoking behavior in a subgroup of smokers. In view of the large subgroup that did not read the manual or did not perform the exercises, alternative ways of conveying the imaginal retraining technique should be sought (e.g., demonstration via video clips). To conclude, imaginal retraining may represent a simple low-threshold technique to reduce smoking and assist current evidence-based treatment programs targeted at abstinence. It needs to be tested whether its mechanism of action deviates from standard ABM.

BACKGROUND: According to Young's schema theory, Early Maladaptive Schemas (EMSs) arise due to the violation of core emotional needs during childhood. It seems likely that parents have difficulties in satisfying their children's emotional needs if they have high levels of EMSs themselves. AIMS: This study investigated whether the extent of EMSs in parents is associated with the extent of EMSs in their offspring. Moreover, we tested for two putative mechanisms that account for this association: parental coping styles and parenting behaviour. METHODS: Sixty dyads of parents (mother or father) and their adult children (N = 120), recruited from the general population, completed the Young Schema Questionnaire. The parents rated their schema coping styles and the children retrospectively rated the parenting of the participating parent. RESULTS: As expected, parents' EMSs were significantly associated with EMSs in their offspring. This association was accounted for by the parental coping style Overcompensation and the adverse parenting that the child remembered. The parental coping style Avoidance did not account for the association. CONCLUSIONS: This study provides preliminary evidence for the notion that EMSs are passed on from one generation to the next via parental coping and parenting. Our findings thus support the assumption of schema theory that EMSs are connected to the family environment in terms of adverse parenting. If further confirmed, this has relevant implications for family-based interventions.

BACKGROUND: Social stress and negatively valenced cognitive representations of the self (self-schemas) play an important role in the formation of delusions. However, it has not been investigated whether and which self-schemas explain paranoid responses to social stress. Building on the framework of schema theory, the aim of this study was thus to investigate whether more pronounced early maladaptive schemas (EMSs) were associated with increased paranoid ideation after a social stress induction in patients with persecutory delusions (PD). METHOD: Patients with PD (n = 20) and healthy controls (n = 40) were assessed for EMSs with the Young Schema Questionnaire. They were then exposed to a social stress situation in which they were socially excluded in a Cyberball paradigm. Prior to and after the social stress induction, paranoid symptoms were assessed. RESULTS: Patients with PD responded with a stronger increase in paranoia and revealed a significantly higher EMS total score compared to the healthy controls. As expected, higher increases in paranoia following the social stress were accounted for by higher EMS total scores. Exploratory analyses showed that particularly the specific EMSs Defectiveness/Shame and Enmeshment/Undeveloped Self were associated with the increase in paranoia. CONCLUSIONS: EMSs are associated with stress-related symptom increases in patients with PD. It thus seems worthwhile to further investigate the relevance of specific schemas for paranoia. The findings also suggest that addressing EMSs in psychological treatment of patients with PD holds potential.

Paranoia is characterized by a lack of perceived social safeness and associated negative affect. Low self-esteem, negative self-concepts and negative emotions have been shown to contribute to paranoid symptom formation. Thus, interventions focusing on affiliation and positive affect might be particularly helpful for patients with paranoia. The present study experimentally tested the effect of a one-session, brief compassion-focused imagery derived from Compassion-Focused Therapy (Gilbert, ) versus a control imagery condition in a repeated measures randomized design. A negative affective state was induced via in-sensu exposure to a recent distressful social situation in order to provide a minimum level of threat-related arousal to be down-regulated by the interventions thereafter. The sample consisted of psychotic patients with paranoid ideation (N = 51) who were randomly assigned to one of the experimental conditions. Effects on postulated causal mechanisms, i.e., self-relating (self-reassurance, self-compassion, self-criticism), and affect (self-reported affective states, skin conductance levels) as well as on state paranoia, were tested. Subjective benefit and appraisals of the intervention were explored. There were no specific intervention effects on negative self-relating, negative affect and skin-conductance or on paranoia. However, compassion-focused imagery had significant effects on self-reassurance and happiness. Explorative analyses revealed that the majority of the participants appraised the intervention in a positive manner, indicating good acceptance. The intervention showed an effect on some of the postulated mechanisms but not on others, which might have been because of its brevity. Further investigation of interventions targeting affiliation for people with paranoid experiences appears worthwhile. Copyright © 2016 John Wiley & Sons, Ltd. KEY PRACTITIONER MESSAGE: Affiliative imagery work is feasible and appraised positively in psychotic patients. Brief compassion focused imagery increased feelings of happiness and reassurance but did not improve negative self-relating, negative affect or paranoia. Further investigation is warranted to identify which patients benefit most from affiliative imagery.

Previous studies have shown that natural window views are beneficial for mental health, but it is still unclear which specific features constitute a 'natural' window view. On the other hand, studies on image analysis found that low-level visual features (LLVFs) are associated with perceived naturalness, but mainly conducted experiments with brief stimulus presentations. In this study, research on the effects of window views on mental health was combined with the detailed analysis of LLVFs. Healthy adults rated window views from their home and sent in photographs of those views for analysis. Content validity of the 'ecological' view assessment was evaluated by checking correlations of LLVFs with window view ratings. Afterwards, it was explored which of the LLVFs best explained variance in perceived percentage of nature and man-made elements, and in ratings of view quality. Criterion validity was tested by investigating which variables were associated with negative affect and impulsive decision-making. The objective and subjective assessments of nature/sky in the view were aligned but objective brightness was unreliable. The perceived percentage of nature was significantly explained by green pixel ratio, while view quality was associated with fractals, saturation, sky pixel ratio and straight edge density. The higher subjective brightness of rooms was associated with a lower negative affect, whereas results for impulsive decision-making were inconsistent. The research highlights the validity to apply LLVFs analysis to ecological window views. For affect, subjective brightness seemed to be more relevant than LLVFs. For impulsive decision-making, performance context needs to be controlled in future studies.

OBJECTIVES: The main objective of the present study was to investigate whether assessments of psychopathology vs. character strengths were associated with systematic differences concerning transient psychological states (i.e., cognitive performance, state mood, optimism, therapy motivation, perceived stigma) in individuals with psychotic disorders. An additional goal was to evaluate the acceptance and appraisal of a subsequent online character-strength intervention, consisting of top-two strengths feedback, and to explore associations between character strengths and psychotic symptoms. The study thus aimed to contribute to the discussion on the extension of current treatment approaches for schizophrenia through positive psychological interventions. METHODS: The study was implemented online applying a randomized within-subject cross-over design in N = 39 patients with self-reported psychosis. After a baseline assessment, briefly capturing psychological states (including cognition: TMT A/B, positive and negative affect, motivation for change/ therapy, optimism, and self-stigma) participants were randomly assigned to a first questionnaire block, which addressed either individual character strengths (VIA-IS) or psychopathology (CAPE & BSI). This was followed by a second, brief assessment of transient psychological states, whereafter the second questionnaire block was conducted, this time with the respective opposite (strengths or psychopathology) assessment. A final psychological states assessment was conducted. Afterwards, participants received feedback on their top-two strengths and a brief psycho-education, followed by a qualitative assessment. RESULTS: Contrary to expectations, there were no differences between the psychological states after the pathology vs. character strengths assessment blocks. Character strengths mainly correlated negatively with negative symptoms, with medium to large effect sizes. Participants were generally satisfied with the intervention and rated a focus on personal strengths in psychotherapy as highly important. CONCLUSION: Our main hypothesis stating that the assessment of character strengths (vs. psychopathology) is associated with differences in subsequent psychological states could not be confirmed. Qualitative findings indicate that the emphasis on individual character strengths interventions is well accepted and viewed as important. The associations of character strengths with negative symptoms are important from the background of the cognitive model or defeatist beliefs (e.g., amotivation due to perceiving the self as 'incapable'), which could be addressed in experimental or intervention studies targeting character strengths.

BACKGROUND: Subjective cognitive decline (SCD) is considered to be a preliminary stage of dementia, and its prevalence is increasing with age. OBJECTIVE: We aimed to study the association of SCD with health-related quality of life (HRQoL) in a large population-based sample. METHODS: We analyzed data of the first 10,000 participants from the Hamburg City Health Study in Germany, a single center prospective cohort study, aged between 45 and 74 years that scored higher than 25 points in the Mini-Mental State Examination and had no known pre-existing dementia. HRQoL was assessed by the EQ-5D-5âL index, as well as the mental (MCS) and physical component summary (PCS) score of the Short Form-8. We computed linear regression analyses with 99% bias-corrected and accelerated (BCa) confidence intervals (CI) from 10,000 bootstrap samples to investigate the association between SCD and different indicators of HRQoL, while controlling for depression (PHQ-9), age, sex, and education as potential confounders. RESULTS: Of 7,799 eligible participants (mean (SD) age 62.01 (8.41) years, 51.1% female), 3,708 (47.5%) reported SCD. Participants with SCD were older (62.7 versus 61.4 years) and more frequently female (54.2% versus 48.2%). SCD was independently associated with a lower EQ-5D-5âL index (ß=-0.01, 99% BCa CIâ=â[-0.020, -0.003], pâ<â0.001) and PCS (ß=-1.00, 99% BCa CIâ=â[-1.48, -0.51], pâ<â0.001) but not with MCS score. CONCLUSION: In a population of middle-aged to elderly participants, there is a significant negative association between SCD and HRQoL across different instruments of HRQoL measurement independent of depression, demographics, and education.

The indirect pandemic consequences could by far exceed the direct effects of SARS-CoV-2 in terms of costs, morbidity, and mortality. This essay includes a proposed method (matrix) to visualize virus-related and psychosocial risks for different populations side by side in a systematic and concise manner. COVID-19-related and psychosocial vulnerability, stressors, direct and indirect consequences are derived on a theoretical and empirical basis. An exemplary quantification of the matrix for the vulnerable group of people with severe mental illness revealed a very high risk for severe COVID-19 consequences, as well as a pronounced risk for psychosocial collateral effects. The proposed approach could be further discussed for a risk-graded pandemic management, crisis recovery, and future preparedness to adequately address psychosocial collateral effects and better identify and protect vulnerable groups in this regard.

The interest in the response to contours has recently re-emerged, with various studies suggesting a universal preference for curved over angular stimuli. Although no consensus has yet been reached on the reasons for this preference, similar effects have been proposed in interior environments. However, the scarcely available research primarily depends on schematic or unmatched stimuli and faces heterogeneity in the reported results. In a within-subject design, we investigated the claimed contour effect in photo-realistic indoor environments using stimulus material previously tested in virtual reality (VR). A total of 198 online participants rated 20 living room images, exclusively manipulated on the contours (angular vs. curved) and style (modern vs. classic) levels. The scales represented aesthetic (beauty and liking) and stress (rest and stress) responses. Beyond our main focus on contours, we additionally examined style and sex effects to account for potential interactions. Results revealed a significant main effect of contours on both aesthetic (η2 g = 1-2%) and stress (η2 g = 8-12%) ratings. As expected, images of curved (vs. angular) contours scored higher on beauty, liking, and rest scales, and lower on stress. Regarding interactions with style, curvature was aesthetically preferred over angularity only within images depicting modern interiors, however, its positive effect on stress responses remained significant irrespective of style. Furthermore, we observed sex differences in aesthetic but not in stress evaluations, with curvature preference only found in participants who indicated female as their sex. In sum, our study primarily confirms positive effects of curvature, however, with multiple layers. First, the impact on aesthetic preference seems to be influenced by individual and contextual factors. Second, in terms of stress responses, which might be especially relevant for designs intended to promote mental-health, the consistent effects suggest a more generalizable, potentially biophilic characteristic of curves. To the best of our knowledge, this is the first study to demonstrate these effects in fully-matched, photo-realistic, and multi-perspective interior design stimuli. From the background of a previous VR trial from our research group, whereby the same rooms did not elicit any differences, our findings propose that static vs. immersive presentations might yield different results in the response to contours.
RESUMO
BACKGROUND: Imaginal retraining, a type of approach-bias-modification performed in one's own imagination, is effective in reducing alcohol craving in problem drinkers. This study aims to segregate three main components of the original technique and compare their effectiveness in reducing craving and alcohol consumption. METHODS: The study was conducted online. Interested individuals wishing to reduce their alcohol consumption underwent a baseline assessment (T0), whereby a total of N = 200 included participants were randomly assigned to one of four study arms. There were three active groups receiving different training manuals: psychoeducation + advice only (PE), PE + a simplified motor in-sensu AAT instruction (AAT0), and the 'enriched' original imaginal retraining technique (including the components PE + enhanced movements + an embodied cognition/ emotion induction instruction) (AAT+), vs. a wait-list control (WLC). Participants in the three active arms were instructed to train twice a day (10 mins. each) over the course of four weeks, whereafter a post-test was conducted (T1). A follow-up took place one month later (T2). Repeated measures ANOVAs were computed to test for differential changes of the four groups over time (group*time interaction effects) concerning craving and alcohol consumption. Both per-protocol and intention-to-treat analyses (PPA, ITTA) were conducted. RESULTS: In both PPA and ITTA, significant group*time interaction effects were identified, whereby false-discovery-rate corrected post-hoc tests revealed that AAT0 most consistently reduced craving with stability towards follow-up. Results concerning alcohol consumption (g ethanol) were inconsistent. CONCLUSION: This study demonstrates that a simplified version of the imaginal retraining technique yields consistent results concerning craving reduction. This may hint towards the central importance of the core element of retraining: a movement of pushing (imagined) alcoholic beverages away. Possibly, more complex forms of imaginal retraining need further instruction than a written manual, such as instructive videos.

Hypertension is a global public health concern and an important contributor to cardiovascular disease. It remains disputed how important life circumstances are for the etiology of hypertension. Thus, the aim of this study is to assess the spatial variation of hypertension within an urban population and to investigate the association with the quality of life of city dwellers and their subjective evaluation of their residential district, as well as their home environment, using the example of Hamburg, Germany. In this cross-sectional study, the first 10,000 participants from the Hamburg City Health Study (HCHS) were analysed. Only participants who had resided at the current address for a minimum of five years were considered. In the descriptive analysis, participants with and without arterial hypertension were compared considering various parameters. The subjective quality of the living environment was obtained using an appropriate subjective living environment index. Quality of life was mapped using the EuroQol Group quality of life questionnaire (EQ-5D) score and the two (mental and physical health) scores of the Short Form Health Questionnaire SF-8. The Gini-coefficient was used to quantify the regional economic variation within Hamburg. Linear and logistic regression analyses were performed. Regional levels were 68 city district clusters in Hamburg. The analysis included n = 8192 participants living at least five years in Hamburg at the time of participation in the HCHS. There was a spatial variation in the prevalence of arterial hypertension within Hamburg. Prevalence rates between city district clusters ranged from 50.0% to 88.5%. The results showed that city district clusters with a worse subjective perception of the living environment were partly associated with an increased prevalence of arterial hypertension. Furthermore, a negative association was observed between arterial hypertension prevalence and the sociodemographic status of participants in the city district clusters. Thus, participants with a high level of education suffered less frequently from arterial hypertension than participants with a rather low level of education. The subjective living environment index and quality of life were significantly related to the occurrence of arterial hypertension; however, more extensive and detailed studies are necessary to derive possible clinical implications.

BACKGROUND AND AIM: No large-scale, longitudinal clinical study has examined whether patients with different types of eating disorders (ED) have an increased risk of a subsequent alcohol use disorder (AUD). This study aimed to assess the ongoing risk of receiving a diagnosis of AUD following a first-time diagnosis of anorexia nervosa (AN), bulimia nervosa (BN), or unspecified ED (USED). DESIGN: Retrospective cohort study. SETTING: Danish nationwide registries, January 1994 to December 2018. PARTICIPANTS: A total of 20 759 ED patients and 83 036 controls were followed from the date of first ED diagnosis (index date) until the date of first AUD diagnosis, death, emigration, or the end of the study. Controls were selected in a 1:4 ratio and matched on month and year of birth, gender and ethnicity. MEASUREMENTS: We obtained data on ED (AN, BN, USED; exposure) and AUD (abuse/dependence; outcome) diagnoses as well as sociodemographics and other psychiatric diagnoses. Time to AUD was generated from the index date. Risk of AUD after the index date was assessed among those without a prior AUD diagnosis while adjusting for sociodemographics and prior psychiatric diagnoses. FINDINGS: Compared with controls, an increased relative risk of AUD after the index date was observed in AN patients throughout the study lasting 15 + years (adjusted hazard ratios [HRs] ranging from 2.49 [99% CI = 1.46, 4.25] to 6.83 [2.84, 16.41]), in BN patients during the first year of follow-up and from 2 years onward (2.72 [1.66, 4.44] to 17.44 [6.01, 50.63]), and in USED patients during the first year and 2-15 years of follow-up (2.52 [1.54, 4.14] to 14.17 [5.86, 34.27]). In all three groups, estimates were highest during the first year, particularly among BN patients. CONCLUSIONS: Patients with anorexia nervosa, bulimia nervosa, or unspecified eating disorders appear to have an increased ongoing risk of receiving a diagnosis of alcohol use disorder following their first eating disorder diagnosis compared with controls.

Imaginal retraining is a variant of approach bias modification and transfers the method into one's own mind. As the technique contains multiple elements, this pilot study aimed to dismantle which of its components is most efficient in reducing craving for high-calorie food. A total of 113 women were randomly allocated to one out of six conditions containing a short intervention to mentally manipulate a picture displaying high-calorie foods. Four of the interventions involved different combinations of elements of the imaginal retraining technique, while the remaining two conditions comprised thought suppression or merely observing a picture. Participants rated their level of craving, as well as three pictures containing healthy and unhealthy foods regarding their pleasantness before and after the interventions took place. Within-group changes were assessed with paired t-tests (in case of non-normal data Wilcoxon paired t-tests) and between-group differences with one-way ANOVAs (non-parametric Kruskal-Wallis tests). A trend level reduction in craving was found in the imaginal retraining condition with and without a movement. A post hoc analysis of both conditions joint together showed a statistically significant reduction in craving. In addition, positive picture appraisal for unhealthy foods was significantly reduced in both imaginal retraining conditions (with and without movement) with medium to large effect sizes. This study demonstrated that imaginal retraining with an arm movement can reduce craving and picture appraisal for high-calorie foods significantly in a one-time application. It is a promising technique to reduce appraisal for unhealthy high-calorie foods. Future studies should repeat the experiment in situations of high craving and allow for a personalized selection of stimuli.
