ARFID: old wine in a new bottle? Commentary on… avoidant/restrictive food intake disorder

In this commentary, some aspects of the context of this diagnosis are considered. It is suggested that avoidant/restrictive food intake disorder (ARFID) is principally a reconfiguration of existing problems. However, it is also stressed that we still need to develop treatments that help patients and their families, given the expectation that has been fuelled by the promotion of the new diagnostic scheme. In developing those therapies, we should not forget that we previously had a number of psychosocial treatment approaches that were helpful for such children when their problems were labelled differently

The Three-Legged Stool of Evidence-Based Practice in Eating Disorder Treatment: Research, Clinical, and Patient Perspectives

Background Evidence-based practice in eating disorders incorporates three essential components: research evidence, clinical expertise, and patient values, preferences, and characteristics. Conceptualized as a ‘three-legged stool’ by Sackett et al. in 1996 (BMJ), all of these components of evidence-based practice are considered essential for providing optimal care in the treatment of eating disorders. However, the extent to which these individual aspects of evidence-based practice are valued among clinicians and researchers is variable, with each of these stool ‘legs’ being neglected at times. As a result, empirical support and patient preferences for treatment are not consistently considered in the selection and implementation of eating disorder treatment. In addition, clinicians may not have access to training to provide treatments supported by research and preferred by patients. Despite these challenges, integrating these three components of evidence-based practice is critical for the effective treatment of eating disorders. Discussion Current research supports the use of several types of psychotherapies, including cognitive-behavioral, interpersonal, and family-based therapies, as well as certain types of medications for the treatment of eating disorders. However, limitations in current research, including sample heterogeneity, inconsistent efficacy, a paucity of data, the need for tailored approaches, and the use of staging models highlight the need for clinical expertise. Although preliminary data also support the importance of patient preferences, values, and perspectives for optimizing treatment, enhancing treatment outcome, and minimizing attrition among patients with eating disorders, the extent to which patient preference is consistently predictive of outcome is less clear and requires further investigation. Summary All three components of evidence-based practice are integral for the optimal treatment of eating disorders. Integrating clinical expertise and patient perspective may also facilitate the dissemination of empirically-supported and emerging treatments as well as prevention programs. Further research is imperative to identify ways in which this three-legged approach to eating disorder treatment could be most effectively implemented

Cost of College

We propose that we should alter the way public post-secondary institutions are funded in Ohio and suggest that the state of Ohio should subsidize some cost for the institution. In return, we hope this would trigger the institutions to cut tuition cost and in return, so students will have less of a financial burden when considering higher education.https://corescholar.libraries.wright.edu/raider_academy/1008/thumbnail.jp

Low intensity psychological interventions for the treatment of feeding and eating disorders: a systematic review and meta-analysis

BACKGROUND: Feeding and eating disorders are associated with significant illness burden and costs, yet access to evidence-based care is limited. Low intensity psychological interventions have the potential to increase such access. METHODS: A systematic review and meta-analysis were conducted on the use of low intensity psychological interventions for the treatment of feeding and eating disorders. Studies comparing low intensity psychological interventions against high intensity therapies and non-eating disorder specific psychological interventions were included, as well as those with waiting list control arms. There were three primary outcomes: eating disorder psychopathology, diagnostic and statistical manual of mental disorders (DSM) severity specifier-related outcomes and rates of remission/recovery. RESULTS: Thirty-three studies met the inclusion criteria, comprising 3665 participants, and 30 studies were included in the meta-analysis. Compared to high intensity therapies, low intensity psychological interventions were equivalent on reducing eating disorder psychopathology (g = - 0.13), more effective at improving DSM severity specifier-related outcomes (g = - 0.15), but less likely to achieve remission/recovery (risk ratio (RR) = 0.70). Low intensity psychological interventions were superior to non-eating disorder specific psychological interventions and waiting list controls across all three primary outcomes. CONCLUSION: Overall, findings suggest that low intensity psychological interventions can successfully treat eating disorder symptoms. Few potential moderators had a statistically significant effect on outcome. The number of studies for many comparisons was low and the methodological quality of the studies was poor, therefore results should be interpreted with caution. More research is needed to establish the effectiveness of low intensity psychological interventions for children and young people, as well as for individuals with anorexia nervosa, avoidant/restrictive food intake disorder, pica and rumination disorder

Multiple quantum phases in artificial double-dot molecules

We study coupled semiconductor quantum dots theoretically through a generalized Hubbard approach, where intra- and inter-dot Coulomb Correlation, as well as tunneling effects are described on the basis of realistic electron wavefunctions. We find that the ground-state configuration of vertically-coupled double dots undergoes non-trivial quantum transitions as a function of the inter-dot distance d; at intermediate values of d we predict a new phase that should be observable in the addition spectra and in the magnetization changes.Comment: RevTeX, 4 pages, 4 ps figures, to appear in Solid State Communication

A study of changes in genetic and environmental influences on weight and shape concern across adolescence

The goal of the current study was to examine whether genetic and environmental influences on an important risk factor for disordered eating, weight and shape concern (WSC), remained stable over adolescence. This stability was assessed in two ways: whether new sources of latent variance were introduced over development, and whether the magnitude of variance contributing to the risk factor changed. We examined an 8-item WSC sub-scale derived from the Eating Disorder Examination using telephone interviews with female adolescents. From three waves of data collected from female-female same sex twin pairs from the Australian Twin Registry, a subset of the data (which included 351 pairs at Wave 1) was used to examine three age cohorts: 12-13, 13-15, and 14-16 years. The best fitting model contained genetic and environmental influences, both shared and non-shared. Biometric model fitting indicated that non-shared environmental influences were largely specific to each age cohort, and results suggested that latent shared environmental and genetic influences that were influential at 12-13 years continued to contribute to subsequent age cohorts, with independent sources of both emerging at ages 13-15. The magnitude of all three latent influences could be constrained to be the same across adolescence. Ages 13-15 was indicated as a time of risk for the development of high levels of WSC given that most specific environmental risk factors were significant at this time (e.g., peer teasing about weight, adverse life events), and indications of the emergence of new sources of latent genetic and environmental variance over this period.NHMRC Grants 324715 and 480420

Definitions and clinical guidance on the enteral dependence component of the avoidant/restrictive food intake disorder diagnostic criteria in children

The aim of the current paper is to offer definitive guidance on weaning children who are reliant on nasogastric/gastrostomy feeding tubes. To date, no internationally recognised definitions or principles for interventions exist and clinics have been reliant on creating their own unique intervention criteria. To achieve the aim, two goals are set out within the current paper. The first goal was to definitively define the process of tube weaning. In order to achieve this, both tube dependency and oral eating also required definitions. It is necessary for these two additional definitions to fully understand the process of tube weaning and the transition that the child is making within these clinical interventions. The second goal of this paper was to propose a set of minimum measurement criteria within a tube weaning protocol so that different clinical practices and perspectives may be measured accurately. This would then allow outcomes from different clinical services to be compared for efficacy. The culmination of this paper is a set of five core principles that should govern clinics that adhere to the auspices of evidence-based practice. These principles, if adopted, will provide the basis of a set of internationally recognised criteria within this field of paediatric gastroenterology

Associations between Blood Metabolic Profile at 7 Years Old and Eating Disorders in Adolescence: Findings from the Avon Longitudinal Study of Parents and Children

Eating disorders are severe illnesses characterized by both psychiatric and metabolic factors. We explored the prospective role of metabolic risk in eating disorders in a UK cohort (n = 2929 participants), measuring 158 metabolic traits in non-fasting EDTA-plasma by nuclear magnetic resonance. We associated metabolic markers at 7 years (exposure) with risk for anorexia nervosa and binge-eating disorder (outcomes) at 14, 16, and 18 years using logistic regression adjusted for maternal education, child's sex, age, body mass index, and calorie intake at 7 years. Elevated very low-density lipoproteins, triglycerides, apolipoprotein-B/A, and monounsaturated fatty acids ratio were associated with lower odds of anorexia nervosa at age 18, while elevated high-density lipoproteins, docosahexaenoic acid and polyunsaturated fatty acids ratio, and fatty acid unsaturation were associated with higher risk for anorexia nervosa at 18 years. Elevated linoleic acid and n-6 fatty acid ratios were associated with lower odds of binge-eating disorder at 16 years, while elevated saturated fatty acid ratio was associated with higher odds of binge-eating disorder. Most associations had large confidence intervals and showed, for anorexia nervosa, different directions across time points. Overall, our results show some evidence for a role of metabolic factors in eating disorders development in adolescence

Childhood overeating is associated with adverse cardiometabolic and inflammatory profiles in adolescence

Childhood eating behaviour contributes to the rise of obesity and related noncommunicable disease worldwide. However, we lack a deep understanding of biochemical alterations that can arise from aberrant eating behaviour. In this study, we prospectively associate longitudinal trajectories of childhood overeating, undereating, and fussy eating with metabolic markers at age 16 years to explore adolescent metabolic alterations related to specific eating patterns in the first 10 years of life. Data are from the Avon Longitudinal Study of Parents and Children (n = 3104). We measure 158 metabolic markers with a high-throughput (1H) NMR metabolomics platform. Increasing childhood overeating is prospectively associated with an adverse cardiometabolic profile (i.e., hyperlipidemia, hypercholesterolemia, hyperlipoproteinemia) in adolescence; whereas undereating and fussy eating are associated with lower concentrations of the amino acids glutamine and valine, suggesting a potential lack of micronutrients. Here, we show associations between early behavioural indicators of eating and metabolic markers

Quantum phases in artificial molecules

The many-body state of carriers confined in a quantum dot is controlled by the balance between their kinetic energy and their Coulomb correlation. In coupled quantum dots, both can be tuned by varying the inter-dot tunneling and interactions. Using a theoretical approach based on the diagonalization of the exact Hamiltonian, we show that transitions between different quantum phases can be induced through inter-dot coupling both for a system of few electrons (or holes) and for aggregates of electrons and holes. We discuss their manifestations in addition energy spectra (accessible through capacitance or transport experiments) and optical spectra.Comment: 29 pages, 8 figures (ps and eps), LaTeX 2e, ELSART package.
