Adults living with obesity have a higher risk of eating disorders and disordered eating behaviours such as binge eating(1,2). However, the prevalence of disordered eating/eating disorders in adults presenting for obesity treatment is unknown and this information is needed to guide service provision. This systematic review aimed to estimate the prevalence of disordered eating/eating disorders in adults presenting for obesity treatment. Embase, MEDLINE and PsycINFO were searched to March 2024. Eligible studies (k) measured disordered eating/eating disorders in adults with overweight/obesity presenting for obesity treatment and included ≥ 325 participants to ensure a representative sample. Prevalence estimates were synthesised using random effect meta-analysis. 81 studies were included (n = 92,002, 75.9% female, median (IQR) age 44 (6) years, BMI 45 (11) kg/m2. Most studies were conducted in the United States (k = 44) and Italy (k = 15). Most prevalence data related to binge eating disorder or binge eating severity. The pooled prevalence of binge eating disorder, assessed by clinical interview, was 17% (95% CI: 12–22, 95% prediction interval (PI): 0–42, k = 19, n = 13447, τ2 = 0.01) using DSM-IV criteria and 12% (95% CI: 5–20, 95% PI: 0–40, k = 9, n = 7680, τ2 = 0.01) using DSM-V criteria. The pooled prevalence for severe binge eating (Binge Eating Scale score > 25) was 12% (95% CI: 8–16, 95% PI: 0–31, k = 18, n = 12136, τ2 = 0.01). For binge eating disorder, measured by clinical interview, the prevalence range for females and males was 14.9 to 27.0% (k = 12), and 4.0 to 24.1% (k = 3) respectively. For moderate to severe binge eating (Binge Eating Scale score ≥ 18) the prevalence for females and males ranged from 20.0 to 32.8%, and 7.1 to 77.5% (k = 2). Three studies reported prevalence by ethnicity. The prevalence of severe binge eating (Binge Eating Scale scores ≥ 27) was 9.5 to 41.7% in white populations (k = 2), 7.5 to 35.8% in black populations (k = 2), and 5.7% in Hispanic populations (k = 1). One study reported binge eating disorder, assessed by clinical interview, for white, black and Hispanic populations and reported prevalence of 15.3%, 11.3% and 11.4% respectively. Overall, there was high variability in the prevalence of binge eating and binge eating disorder in adults presenting for obesity treatment, with available data indicating prevalence can range up to 42%. It is important to identify which population level factors drive this heterogeneity to inform service provision however, the limited data highlights a significant knowledge gap in the reporting of eating disorders in underrepresented populations which needs to be addressed.

To enable a truly circular economy in product engineering, the development of products in generations must be considered. Thus, we strive to enable a forward-looking circularity approach, proposing the integration of system generation engineering (SGE) with circular economy principles. By analysing the qualitative interrelations among product generations driven by distinct value preservation strategies on various value creation tiers ("R-strategies"), we extend prior SGE research to advance model theory and support practical application of circular product engineering.

Water scarcity and resource depletion can be expected during the climate crisis. Therefore, thermally loaded processes in particular, must be made more efficient in the future. Heat exchangers will play a key role in this optimization process. More efficient designs allow a greater heat flow to be removed from processes while mass flows remain constant. In this context, the heat-transferring wall of heat exchangers is a focus of current research on the design of heat exchangers. The aim is to increase the heat-transferring surface of the wall as much as possible and to keep the design space as compact as possible. Therefore, this study investigates the suitability of the differential-growth method for generating complex heat-transferring walls for heat exchangers using CFD-analysis. Firstly, a framework for generating the wall structures and a computational model for predicting the design influence of such structures for the thermal and fluid-dynamic behavior of the heat exchanger are presented. Thereby, the potential of such wall structures is analyzed in this study. Furthermore, the study identified weaknesses of such walls designed with the differential-growth method, which should be the focus of future investigations.

The cornerstone of obesity treatment is behavioural weight management, resulting in significant improvements in cardio-metabolic and psychosocial health. However, there is ongoing concern that dietary interventions used for weight management may precipitate the development of eating disorders. Systematic reviews demonstrate that, while for most participants medically supervised obesity treatment improves risk scores related to eating disorders, a subset of people who undergo obesity treatment may have poor outcomes for eating disorders. This review summarises the background and rationale for the formation of the Eating Disorders In weight-related Therapy (EDIT) Collaboration. The EDIT Collaboration will explore the complex risk factor interactions that precede changes to eating disorder risk following weight management. In this review, we also outline the programme of work and design of studies for the EDIT Collaboration, including expected knowledge gains. The EDIT studies explore risk factors and the interactions between them using individual-level data from international weight management trials. Combining all available data on eating disorder risk from weight management trials will allow sufficient sample size to interrogate our hypothesis: that individuals undertaking weight management interventions will vary in their eating disorder risk profile, on the basis of personal characteristics and intervention strategies available to them. The collaboration includes the integration of health consumers in project development and translation. An important knowledge gain from this project is a comprehensive understanding of the impact of weight management interventions on eating disorder risk.

According to normative decision-making theories, the composition of a choice setshould not affect people’s preferences regarding the different options.This assumption contrasts with decades of research that have identified multiplesituations in which this principle is violated, leading to context effects.Recently, research on context effects has been extended to the domain ofexperience-based choices, where it has been shown that forgone outcomes fromirrelevant alternatives affect preferences — an accentuation effect. Morespecifically, it has been shown that an option presented in a situation in whichits outcomes are salient across several trials is evaluated more positively thanin a context in which its outcomes are less salient. In the present study, weinvestigated whether irrelevant information affects preferences as much asrelevant information. In two experiments, individuals completed a learning taskwith partial feedback. We found that past outcomes from non-chosen options,which contain no relevant information at all, led to the same accentuationeffect as did counterfactual outcomes that provided new and relevantinformation. However, if the information is entirely irrelevant (from optionsthat could not have been chosen), individuals ignored it, thus ruling out apurely perceptual account of the accentuation effect. These results providefurther support for the influence of salience on learning and highlight thenecessity of mechanistic accounts in decision-making research.

The spectrum of adverse mental health trajectories caused by sexual abuse, broadly defined as exposure to rape and unwanted physical sexual contact, is well-known. Few studies have systematically appraised the epidemiology and impact of sexual abuse among boys and men. New meta-analytic insights (k = 44; n = 45 172) reported by Zarchev and colleagues challenge assumptions that men experiencing mental ill health rarely report sexual abuse exposure. Adult-onset sexual abuse rates of 1–7% are observed in the general population, but for men experiencing mental ill health, adult lifetime prevalence was 14.1% (95% CI 7.3–22.4%), with past-year exposure 5.3% (95% CI 1.6–12.8%). We note that these rates are certainly underestimates, as childhood sexual abuse exposures were excluded. Boys and men with a sexual abuse history experience substantial disclosure and treatment barriers. We draw attention to population health gains that could be achieved via implementation of gender-sensitive assessment and intervention approaches for this at-risk population.

In this paper, a proposal for a new method to design load-adaptive microlattice structures for PBF-LB/M manufacturing is presented. For this purpose, a method was developed to stiffen microlattice structures in particular by using self-similar sub-cells to ensure their manufacturability. The quality of the stiffness increase was investigated and verified by finite element simulations. Subsequently, the simulation results were critically discussed with respect to their potential for future design processes for architected materials.

Adolescence is associated with heightened vulnerability to symptoms of depression and anxiety. In-person and computerised cognitive behavioural therapy (CBT) are effective treatment options, yet uptake and engagement remain low. Smartphone delivery of CBT offers an alternative, highly accessible method of delivering CBT. However, there is no freely available CBT smartphone application (app) specifically designed to reduce depression and anxiety symptoms in adolescents. The aim of this study was to design a new CBT smartphone app (ClearlyMe) that targets depressive and anxiety symptoms in adolescents. We engaged in a rigorous co-design process with adolescents (n=36), parents (n=15), and mental health professionals (n=32). Co-design involved: (1) discovery of users’ needs, views and preferences by conducting focus groups, (2) defining app features through ideation workshops and user consultations, (3) designing therapeutic CBT content and visual features, and (4) testing prototypes. Users were involved at every step and the process was iterative, with findings carried forward to ensure continued refinement of concepts and features. We found a preference for vibrant, cheerful colours and illustrations and non-endorsement of gamification and chatbots, which contrasted with findings from other studies. Preferences were largely consistent between the three user groups. However, adolescents preferred an app that could be used autonomously without professional support, whereas mental health professionals desired a product for use as a therapy adjunct to support CBT skill development. The importance of co-design, and particularly the inclusion of all stakeholders throughout the entire co-design process, is discussed in relation to the design of ClearlyMe.

Learning new words and, subsequently, a lexicon, is a time-extended process requiring encoding of word-referent pairs, retention of that information, and generalization to other exemplars of the category. Some children, however, fail in one or more of these processes resulting in language delays. The present study examines the abilities of children who vary in vocabulary size (including both children with normal language (NL) and late talking (LT) children) across multiple timescales/processes – known and novel word mapping, novel word retention, and novel noun generalization. Results indicate that children with lower language skills suffer from deficits in quick in-the-moment mapping of known words compared to their NL peers, but age and vocabulary size rather than normative vocabulary ranking or NL/LT status better predicts performance on retention and generalization processes. Implications for understanding language development as a holistic process with multiple interacting variables are discussed.

Psychiatric day hospital treatment concepts have to deal with a wide spectrum of mental disorders. We raised the question, if day hospitals can be differentiated concerning their treatment concepts and if so how much this is reflected in their structural and procedural features. In 1999 a survey was initiated concerning structure, concept and method of treatment in psychiatric day hospitals for adults in Germany. Furthermore data concerning rate of utilization, patients' characteristics and aspects of referral and further treatment were ascertained. One hundred and seventy-three (63.4%) of 273-day hospitals contacted took part in the inquiry. The data were interpreted using multivariate as well as non-parametric procedures. The results show that treatment concepts of day hospitals can be specified as three main areas of function (psychotherapy, crisis intervention orientated treatment alternative, rehabilitation) and four therapeutic orientations (psychodynamic social psychiatric, behavioral social psychiatric, psychodynamic, sociotherapeutic). Structural features are predominantly comparable and the differences found concerning the treatment concepts are especially related to patients' characteristics and some procedural features. The conclusion is that the differentiation of day hospital treatment concepts should be taken into consideration in planning psychosocial treatment services as well as in day hospital evaluation research.

The electrification of organic syntheses is a vividly growing research field and has attracted tremendous attention by the chemical industry. This review highlights aspects of electrosynthesis that are rarely addressed in other articles on the topic: the energy consumption and energy efficiency of technically relevant electro-organic syntheses.

Four examples on different scales are outlined.

Electro-organic synthesis has experienced a renaissance within the past years. This review addresses the energy efficiency or energy demand of electrochemically driven transformations as it is a key parameter taken into account by, for example, decision makers in industry. The influential factors are illustrated that determine the energy efficiency and discussed what it takes for an electrochemical process to be classified as “energy efficient.” Typical advantages of electrosynthetic approaches are summarized and characteristic aspects regarding the efficiency of electro-organic processes, such as electric energy consumption, are defined. Technically well-implemented examples are described to illustrate the possible benefits of electrochemical approaches. Further, promising research examples are highlighted and show that the conversion of fine chemicals is rather attractive than the electrochemical generation of synthetic fuels.
