A framework for a brain-derived nosology of psychiatric disorders.

Current psychiatric diagnoses are not defined by neurobiological measures which hinders the development of therapies targeting mechanisms underlying mental illness 1,2 . Research confined to diagnostic boundaries yields heterogeneous biological results, whereas transdiagnostic studies often investigate individual symptoms in isolation. There is currently no paradigm available to comprehensively investigate the relationship between different clinical symptoms, individual disorders, and the underlying neurobiological mechanisms. Here, we propose a framework that groups clinical symptoms derived from ICD-10/DSM-V according to shared brain mechanisms defined by brain structure, function, and connectivity. The reassembly of existing ICD-10/DSM-5 symptoms reveal six cross-diagnostic psychopathology scores related to mania symptoms, depressive symptoms, anxiety symptoms, stress symptoms, eating pathology, and fear symptoms. They were consistently associated with multimodal neuroimaging components in the training sample of young adults aged 23, the independent test sample aged 23, participants aged 14 and 19 years, and in psychiatric patients. The identification of symptom groups of mental illness robustly defined by precisely characterized brain mechanisms enables the development of a psychiatric nosology based upon quantifiable neurobiological measures. As the identified symptom groups align well with existing diagnostic categories, our framework is directly applicable to clinical research and patient care.

American Academy of Dermatology Guidelines for Managing Atopic Dermatitis.

The American Academy of Dermatology first published a series of guidelines for diagnosing and managing atopic dermatitis in 2014. Twelve clinicians were selected to review, grade, and offer clinical insight on available data regarding the clinical features, symptomology, pathophysiology, education, treatment, and emerging clinical studies on atopic dermatitis (AD). Based on these findings, the AAD released a guideline to streamline information on atopic dermatitis for physicians, recommending using clinical evidence to diagnose and first treating with nonpharmacologic therapies to restore the natural skin barrier. Topical pharmacologic therapies were recommended for improving pruritus and inflammation and newer systemic agents for clinically relevant moderate-to-severe cases. Evidence-based practices were emphasized in comparison to those that lacked therapeutic data. To highlight the emerging evidence and pharmacologic breakthroughs in atopic dermatitis, the AAD produced an updated set of guidelines educating physicians on new agents and their role in treatment. This chapter reviews the AAD guidelines as a tool for managing atopic dermatitis and staying up to date on disease advancements.

Exploring Firearm Access, Carriage, and Possession among Justice-Involved Youth.

Firearm carriage and possession predicts youth firearm violence victimization and perpetration. This study describes self-reported factors associated with firearm access, carriage, and possession among justice-involved youth. We conducted an exploratory, mixed-methods study. Participants were recruited from May 2022 to February 2023 from the Juvenile Justice Collaborative, a diversion program for justice-involved youth. We used online anonymous surveys to investigate exposures related to firearm access, carriage, and possession. We performed semi-structured interviews using the phenomenology framework. We used descriptive statistics to examine firearm exposures by participant demographics. We performed qualitative analyses using an iterative approach with constant comparison to identify key themes. We completed 28 surveys and 5 interviews. Most survey participants identified as male (57%) and Black (61%) with a median age of 18 years. Interview participants described the socialization and cultural normalization of firearms, most prominently among peers. Survey participants reported whether they had ever carried (25%) or possessed (21%) a firearm. Survey and interview participants endorsed protection in the context of increasing violence exposure over time as the primary motivation for firearm possession. Interview participants describe accessing firearms primarily through social networks while survey participants also reported access from strangers (25%) and licensed sellers/gun dealers (18%). In conclusion, justice-involved youth believe firearm carriage and possession may be needed for protection due to increasing violence exposure. Further investigation is necessary to determine interventions that may decrease firearm access, carriage, and possession among justice-involved youth.

Individual differences in motivation to change in individuals with eating disorders: A systematic review.

OBJECTIVE: Motivation to change has been suggested to significantly impact treatment outcomes in eating disorders (EDs). This review will investigate factors associated with motivation to change in EDs with the aim of supporting clinicians to be aware and sensitive to factors that might obstruct recovery and to inform motivation-based interventions. METHOD: Using PRISMA guidelines, this article identified 24 studies through database searches meeting eligibility criteria. Only correlates of motivation were identified, limiting the ability of this review to identify causal relationships. Factors that changed alongside changes in motivation were identified from longitudinal studies. RESULTS: This review identified factors such as individual characteristics, co-morbid psychopathology, lack of treatment autonomy and relationships with others to be associated with motivation to change in individuals with EDs. In addition, motivation to change significantly increased alongside self-esteem and identity re-negotiation when measured longitudinally. DISCUSSION: Motivational interviewing can typically focus on exploring ambivalence to treatment, identifying goals and values, and increasing self-efficacy. However, this review identifies individual and relational factors to be particularly significant and may obstruct recovery from an ED. As such, evidence-based targets have been identified to inform clinicians and motivation-based interventions. PUBLIC SIGNIFICANCE: Knowledge of factors associated with motivation to change in EDs is important to understand those who may have poorer treatment outcomes. Motivation may be improved by supporting individuals' relationship with others and tailoring interventions according to temperament and personality traits. Utilizing an individual's social support as they enter ED treatment may be effective in maximizing motivation to recover.

OBJETIVO: Se ha sugerido que la motivación al cambio impacta significativamente en los resultados del tratamiento en los trastornos de la conducta alimentaria (TCAs). Esta revisión investigará los factores asociados con la motivación al cambio en los TCAs con el objetivo de apoyar a los clínicos para que estén conscientes y sensibles a los factores que podrían obstaculizar la recuperación e informar las intervenciones basadas en la motivación. MÉTODO: Siguiendo las guías PRISMA, este artículo identificó 24 estudios a través de búsquedas en bases de datos que cumplían con los criterios de elegibilidad. Solo se identificaron correlatos de la motivación, lo que limita la capacidad de esta revisión para identificar relaciones causales. Los factores que cambiaron junto con los cambios en la motivación se identificaron a partir de estudios longitudinales. RESULTADOS: Esta revisión identificó factores como características individuales, psicopatología comórbida, falta de autonomía en el tratamiento y relaciones con otros como asociados con la motivación al cambio en individuos con TCAs. Además, la motivación al cambio aumentó significativamente junto con la autoestima y la renegociación de la identidad cuando se midió longitudinalmente. DISCUSIÓN: La entrevista motivacional típicamente puede centrarse en explorar la ambivalencia hacia el tratamiento, identificando metas y valores, y aumentando la autoeficacia. Sin embargo, esta revisión identifica factores individuales y relacionales como particularmente significativos y que pueden obstaculizar la recuperación de un TCA. Como tal, se han identificado objetivos basados en evidencia para informar a los clínicos y a las intervenciones basadas en la motivación.

Interplay of early negative life events, development of orbitofrontal cortical thickness and depression in young adulthood.

Background: Early negative life events (NLE) have long-lasting influences on neurodevelopment and psychopathology. Reduced orbitofrontal cortex (OFC) thickness was frequently associated with NLE and depressive symptoms. OFC thinning might mediate the effect of NLE on depressive symptoms, although few longitudinal studies exist. Using a complete longitudinal design with four time points, we examined whether NLE during childhood and early adolescence predict depressive symptoms in young adulthood through accelerated OFC thinning across adolescence. Methods: We acquired structural MRI from 321 participants at two sites across four time points from ages 14 to 22. We measured NLE with the Life Events Questionnaire at the first time point and depressive symptoms with the Center for Epidemiologic Studies Depression Scale at the fourth time point. Modeling latent growth curves, we tested whether OFC thinning mediates the effect of NLE on depressive symptoms. Results: A higher burden of NLE, a thicker OFC at the age of 14, and an accelerated OFC thinning across adolescence predicted young adults' depressive symptoms. We did not identify an effect of NLE on OFC thickness nor OFC thickness mediating effects of NLE on depressive symptoms. Conclusions: Using a complete longitudinal design with four waves, we show that NLE in childhood and early adolescence predict depressive symptoms in the long term. Results indicate that an accelerated OFC thinning may precede depressive symptoms. Assessment of early additionally to acute NLEs and neurodevelopment may be warranted in clinical settings to identify risk factors for depression.

Adolescent to young adult longitudinal development of subcortical volumes in two European sites with four waves.

Adolescent subcortical structural brain development might underlie psychopathological symptoms, which often emerge in adolescence. At the same time, sex differences exist in psychopathology, which might be mirrored in underlying sex differences in structural development. However, previous studies showed inconsistencies in subcortical trajectories and potential sex differences. Therefore, we aimed to investigate the subcortical structural trajectories and their sex differences across adolescence using for the first time a single cohort design, the same quality control procedure, software, and a general additive mixed modeling approach. We investigated two large European sites from ages 14 to 24 with 503 participants and 1408 total scans from France and Germany as part of the IMAGEN project including four waves of data acquisition. We found significantly larger volumes in males versus females in both sites and across all seven subcortical regions. Sex differences in age-related trajectories were observed across all regions in both sites. Our findings provide further evidence of sex differences in longitudinal adolescent brain development of subcortical regions and thus might eventually support the relationship of underlying brain development and different adolescent psychopathology in boys and girls.

ASES and UCLA Are Responsive Patient-Reported Outcome Measures After Rotator Cuff Repair: A Systematic Review and Meta-analysis.

BACKGROUND: Multiple patient-reported outcome measures (PROMs) have been used to assess shoulder function, but it is unknown which are the most effective. PURPOSE/HYPOTHESIS: The purpose of this study was to report the multiple PROMs used after rotator cuff repair (RCR) and to compare the responsiveness between them. It was hypothesized that the Western Ontario Rotator Cuff PROM would be the most responsive and commonly used in patients undergoing RCR. STUDY DESIGN: Meta-analysis; Level of evidence, 4. METHODS: A systematic review was conducted in accordance with PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) and PRISMA-Searching extension guidelines via PubMed/MEDLINE, Embase (Elsevier), and Web of Science (Clarivate). Patient and study characteristics were extracted. From the studies that met inclusion criteria for responsiveness analysis (≥2 PROMs reported, 1-year minimum follow-up, and pre- and postoperative PROM means and standard deviations reported), the authors compared the responsiveness between PROM instruments using effect size and relative efficiency (RE) if a PROM could be compared with another in ≥10 articles. RESULTS: A total of 252 studies met inclusion criteria (32,072 patients; mean age, 59.6 years; mean body mass index, 28.7; mean follow-up time, 27.8 months). Range of motion was reported in 131 (52%) studies and imaging findings were reported in 123 (49%) studies. There were 67 PROM instruments identified; the most commonly used were the American Shoulder and Elbow Surgeon (ASES) (n = 183; 73%), Visual Analog Scale (VAS) (n = 163; 65%), and Constant (n = 118; 47%) scores. The 3 PROMs with the highest effect sizes were the University of California, Los Angeles (UCLA) (2.51), Western Ontario Rotator Cuff (2.42), and ASES (2.00) scores. Overall, UCLA and ASES scores were the most responsive PROMs. The ASES PROM was more responsive than the VAS (RE, 1.70), Constant (RE, 2.76), Simple Shoulder Test (RE, 1.67), and Single Assessment Numeric Evaluation (RE, 2.14) scores. The UCLA PROM was more responsive than the ASES (RE, 1.03), VAS (RE, 3.66), Constant (RE, 1.72), and Simple Shoulder Test (RE, 1.66) scores. CONCLUSION: ASES and UCLA scores were the most responsive PROMs after RCR. The authors recommend widespread adoption of ASES and UCLA scores for clinical and research standardization; however, the UCLA PROM requires in-person range of motion and strength testing, which is a practical limitation and barrier to long-term follow-up.

Machine learning models for diagnosis and risk prediction in eating disorders, depression, and alcohol use disorder.

This study uses machine learning models to uncover diagnostic and risk prediction markers for eating disorders (EDs), major depressive disorder (MDD), and alcohol use disorder (AUD). Utilizing case-control samples (ages 18-25 years) and a longitudinal population-based sample (n=1,851), the models, incorporating diverse data domains, achieved high accuracy in classifying EDs, MDD, and AUD from healthy controls. The area under the receiver operating characteristic curves (AUC-ROC [95% CI]) reached 0.92 [0.86-0.97] for AN and 0.91 [0.85-0.96] for BN, without relying on body mass index as a predictor. The classification accuracies for MDD (0.91 [0.88-0.94]) and AUD (0.80 [0.74-0.85]) were also high. Each data domain emerged as accurate classifiers individually, with personality distinguishing AN, BN, and their controls with AUC-ROCs ranging from 0.77 to 0.89. The models demonstrated high transdiagnostic potential, as those trained for EDs were also accurate in classifying AUD and MDD from healthy controls, and vice versa (AUC-ROCs, 0.75-0.93). Shared predictors, such as neuroticism, hopelessness, and symptoms of attention-deficit/hyperactivity disorder, were identified as reliable classifiers. For risk prediction in the longitudinal population sample, the models exhibited moderate performance (AUC-ROCs, 0.64-0.71), highlighting the potential of combining multi-domain data for precise diagnostic and risk prediction applications in psychiatry.

Virtually delivered guided self-help for binge eating disorder and bulimia nervosa: findings from a service evaluation.

BACKGROUND: Timely intervention is beneficial to the effectiveness of eating disorder (ED) treatment, but limited capacity within ED services means that these disorders are often not treated with sufficient speed. This service evaluation extends previous research into guided self-help (GSH) for adults with bulimic spectrum EDs by assessing the feasibility, acceptability, and preliminary effectiveness of virtually delivered GSH using videoconferencing. METHOD: Patients with bulimia nervosa (BN), binge eating disorder (BED) and other specified feeding and eating disorders (OSFED) waiting for treatment in a large specialist adult ED out-patient service were offered virtually delivered GSH. The programme used an evidence-based cognitive behavioural self-help book. Individuals were supported by non-expert coaches, who delivered the eight-session programme via videoconferencing. RESULTS: One hundred and thirty patients were allocated to a GSH coach between 1 September 2020 and 30 September 2022; 106 (82%) started treatment and 78 (60%) completed treatment. Amongst completers, there were large reductions in ED behaviours and attitudinal symptoms, measured by the ED-15. The largest effect sizes for change between pre- and post-treatment were seen for binge eating episode frequency (d = -0.89) and concerns around eating (d = -1.72). Patients from minoritised ethnic groups were over-represented in the non-completer group. CONCLUSIONS: Virtually delivered GSH is feasible, acceptable and effective in reducing ED symptoms amongst those with bulimic spectrum disorders. Implementing virtually delivered GSH reduced waiting times, offering a potential solution for long waiting times for ED treatment. Further research is needed to compare GSH to other brief therapies and investigate barriers for patients from culturally diverse groups.

Some dogs can find the payoff-dominant outcome in the Assurance game.

Studies on coordination often present animals with the choice of either cooperating or remaining inactive; however, in nature, animals may also choose to act alone. This can be modeled with the Assurance game, an economic game that has recently been used to explore decision-making in primates. We investigated whether dyads of pet dogs coordinate in the Assurance game. Pairs were presented with two alternatives: they could individually solve an apparatus baited with a low-value reward (Hare) or they could coordinate to solve a cooperative apparatus baited with a high-value reward for each dog (Stag). All individuals matched their partner's choices, but after controlling for side bias, only four out of eleven dyads consistently coordinated on the payoff-dominant strategy (Stag-Stag). Thus, some dogs are capable of finding coordinated outcomes, as do primates, at least when their partner's actions are visible and coordination results in the biggest payoff for both individuals.

Autoimmune Implications in a Patient with Graves' Hyperthyroidism, Pre-eclampsia with Severe Features, and Primary Aldosteronism.

Background and Objectives: Graves' disease (GD) and primary aldosteronism (PA) are two pathologies that can cause significant morbidity and mortality. GD is mediated by autoantibodies, and recent studies have shown autoantibody involvement in the pathophysiology behind both PA and pre-eclampsia. The coexistence of GD and PA, however, is reportedly rare. This report describes a unique case of Graves' hyperthyroidism and concomitant PA in a patient with a history of pre-eclampsia with severe features. Case Presentation: The patient presented at 17 weeks pregnancy with mild hyperthyroidism, negative TSH receptor antibodies, and a low level of thyroid-stimulating immunoglobulins (TSI). Her TSH became detectable with normal thyroid hormone levels, and therefore, no anti-thyroid medication was administered. At 34 weeks she developed pre-eclampsia with severe features, and a healthy child was delivered; her TSH returned to normal. Seven months after delivery, she presented emergently with severe hyperthyroidism, hypertensive crisis, and a serum potassium of 2.5 mmol/L. Her hypertension was uncontrolled on multiple anti-hypertensives. Both TSI and TSH receptor antibodies were negative. The aldosterone(ng/dL)/renin(ng/mL/h ratio was (13/0.06) = 216.7, and abdominal CT imaging demonstrated normal adrenal glands; thus, a diagnosis of PA was made. Her blood pressure was subsequently controlled with only spironolactone at 50 mg 2xday. Methimazole was started but discontinued because of an allergic reaction. Consequently, a thyroidectomy was performed, and pathology revealed Graves' disease. The patient remained well on levothyroxine at 125 mcg/day and spironolactone at 50 mg 2xday three months after the thyroidectomy. Conclusions: This patient manifested severe GD with antibodies undetectable by conventional TSI and TSH receptor assays and accelerated hypertension from PA simultaneously. These conditions were successfully treated separately by spironolactone and thyroidectomy. Autoimmune PA was considered likely given the clinical picture. The diagnosis of PA should be considered in hypertension with GD.

An overview and investigation of relapse predictors in anorexia nervosa: A systematic review and meta-analysis.

OBJECTIVE: An extensive number of predictors has been examined across the literature to improve knowledge of relapse in anorexia nervosa (AN). These studies provide various recovery and relapse definitions, follow-up durations and relapse rates. The current study summarizes these values and predictors of relapse in AN in a review and meta-analysis. METHOD: The study was executed according to PRISMA guidelines. Different databases were searched and studies in which participants did not receive an official clinical diagnosis were excluded. A quality analysis was performed using the National Institute of Health's Study Quality Assessment Tool. Random-effects meta-analyses were conducted to summarize data. RESULTS: Definitions of relapse and recovery were diverse. During an average follow-up period of 31 months an average relapse rate of 37% was found. Predictive variables from 28 studies were grouped in six categories: age and sex, symptoms and behaviors, AN subtype and duration, weight or weight change, comorbidity, and personality. The studies were characterized by non-significant and contradictory results. Meta-analyses were performed for the predictors age, AN duration, pre-treatment BMI, post-treatment BMI and depression. These yielded significant effects for post-treatment BMI and depression: higher pre-treatment depression (SMD = .40 CI [.21-.59] and lower post-treatment BMI (SMD = -.35 CI [-.63 to -.07]) increased relapse chances in AN. DISCUSSION: Our results emphasized a lack of sufficiently powered studies, consistent results, and robust findings. Solely post-treatment BMI and pre-treatment depression predicted relapse. Future research should use uniform definitions, larger samples and better designs, to improve our understanding of relapse in AN. PUBLIC SIGNIFICANCE: Knowledge about predictors is important to understand high relapse rates. Our study performed a review and meta-analysis of relapse predictors in AN. Related to the heterogeneity in studies examining predictors, an overview of relapse and recovery definitions, follow-up durations and relapse rates for AN was provided. Significant effects were found for post-treatment BMI and pre-treatment depression. More studies with uniform definitions are needed to improve clinical implications.

OBJETIVO: En la literatura se ha examinado un amplio número de predictores para mejorar el conocimiento de la recaída en la anorexia nerviosa (AN). Estos estudios proporcionan diversas definiciones de recuperación y recaída, duraciones del seguimiento y tasas de recaída. El presente estudio resume estos valores y predictores de recaída en AN en una revisión y metaanálisis. MÉTODO: El estudio se realizó siguiendo las directrices PRISMA. Se realizaron búsquedas en diferentes bases de datos y se excluyeron los estudios en los que los participantes no recibieron un diagnóstico clínico oficial. Se realizó un análisis de calidad mediante la herramienta de evaluación de la calidad de los estudios del Instituto Nacional de Salud. Se realizaron metaanálisis de efectos aleatorios para resumir los datos. RESULTADOS: Las definiciones de recaída y recuperación fueron diversas. Durante un período de seguimiento promedio de 31 meses se encontró una tasa media de recaída del 37%. Las variables predictivas de 28 estudios se agruparon en seis categorías: edad y sexo, síntomas y conductas, subtipo y duración de la AN, peso o cambio de peso, comorbilidad y personalidad. Los estudios se caracterizaron por resultados no significativos y contradictorios. Se realizaron metaanálisis para los predictores edad, duración de la AN, IMC pretratamiento, IMC postratamiento y depresión. Éstos arrojaron efectos significativos para el IMC postratamiento y la depresión: una mayor depresión pretratamiento (DME = −,40; IC: [21 a, 59] y un menor IMC postratamiento (DME = −,35; IC: [−,63 a −,07]) aumentaron las probabilidades de recaída en la AN. DISCUSIÓN: Nuestros resultados enfatizaron la falta de estudios con suficiente potencia, resultados consistentes y hallazgos robustos. Sólo el IMC postratamiento y la depresión pretratamiento predijeron la recaída. Las investigaciones futuras deberían utilizar definiciones uniformes, muestras más grandes y mejores diseños, para mejorar nuestra comprensión de la recaída en la AN.

Providers' Stigmas and the Effects on Patients with Opioid Use Disorder: A Scoping Review.

Introduction: One of the most prevalent, dangerous stigmas in health care is the complex bias toward patients with opioid use disorder (OUD). This stigma damages the vital patient-provider relationship, further perpetuating the opioid epidemic. Purpose: Unfortunately, research on the relationship between OUD and provider stigma is greatly lacking. To fill this gap, the present in-depth study undertakes a scoping review of research on providers' stigma toward OUD in order to determine how enacted stigma affects treatment plans. Methods: Four databases were used to identify articles published from 1999 to 2021. A comprehensive search strategy was developed through a collaborative process between the researchers and a medical librarian. The researchers used the methodological framework developed by Arksey and O'Malley (2005) and expanded upon by Levac et al.(2010) to chart study characteristics and themes. Results: A total of 196 search items were retrieved. After de-duplication (n=31), remaining articles were screened based on the inclusion and exclusion criteria detailed in the protocol. After both a title/abstract review and full-text review, an additional 158 articles were removed. This yielded a total of seven articles. Three main themes were identified in the literature: (1) rural-urban differences in bias; (2) provider concern regarding legal implications and regulatory concerns; and (3) the belief that OUD is a moral failing rather than a medical diagnosis. Implications: Additional research should further analyze prescribed treatment plans for patients with OUD and utilize this information to create future considerations aimed at reducing opioid-related stigma in healthcare in Appalachia.

A labeled data set of underwater images of fish and crab species from five mesohabitats in Puget Sound WA USA.

The sustainable management of fisheries and aquaculture requires an understanding of how these activities interact with natural fish populations. GoPro cameras were used to collect an underwater video data set on and around shellfish aquaculture farms in an estuary in the NE Pacific from June to August 2017 and June to August 2018 to better understand habitat use by the local fish and crab communities. Images extracted from these videos were labeled to produce a data set that is suitable for use in training computer vision models. The labeled data set contains 77,739 images sampled from the collected video; 67,990 objects (fishes and crustaceans) have been annotated in 30,384 images (the remainder have been annotated as "empty"). The metadata of the data set also indicates whether a physical magenta filter was used during video collection to counteract reduced visibility. These data have the potential to help researchers address system-level and in-depth regional shellfish aquaculture questions related to ecosystem services and shellfish aquaculture interactions.

Differing impact of the COVID-19 pandemic on youth mental health: combined population and clinical study.

BACKGROUND: Identifying youths most at risk to COVID-19-related mental illness is essential for the development of effective targeted interventions. AIMS: To compare trajectories of mental health throughout the pandemic in youth with and without prior mental illness and identify those most at risk of COVID-19-related mental illness. METHOD: Data were collected from individuals aged 18-26 years (N = 669) from two existing cohorts: IMAGEN, a population-based cohort; and ESTRA/STRATIFY, clinical cohorts of individuals with pre-existing diagnoses of mental disorders. Repeated COVID-19 surveys and standardised mental health assessments were used to compare trajectories of mental health symptoms from before the pandemic through to the second lockdown. RESULTS: Mental health trajectories differed significantly between cohorts. In the population cohort, depression and eating disorder symptoms increased by 33.9% (95% CI 31.78-36.57) and 15.6% (95% CI 15.39-15.68) during the pandemic, respectively. By contrast, these remained high over time in the clinical cohort. Conversely, trajectories of alcohol misuse were similar in both cohorts, decreasing continuously (a 15.2% decrease) during the pandemic. Pre-pandemic symptom severity predicted the observed mental health trajectories in the population cohort. Surprisingly, being relatively healthy predicted increases in depression and eating disorder symptoms and in body mass index. By contrast, those initially at higher risk for depression or eating disorders reported a lasting decrease. CONCLUSIONS: Healthier young people may be at greater risk of developing depressive or eating disorder symptoms during the COVID-19 pandemic. Targeted mental health interventions considering prior diagnostic risk may be warranted to help young people cope with the challenges of psychosocial stress and reduce the associated healthcare burden.

The Role of Empathy in Alcohol Use of Bullying Perpetrators and Victims: Lower Personal Empathic Distress Makes Male Perpetrators of Bullying More Vulnerable to Alcohol Use.

Bullying often results in negative coping in victims, including an increased consumption of alcohol. Recently, however, an increase in alcohol use has also been reported among perpetrators of bullying. The factors triggering this pattern are still unclear. We investigated the role of empathy in the interaction between bullying and alcohol use in an adolescent sample (IMAGEN) at age 13.97 (±0.53) years (baseline (BL), N = 2165, 50.9% female) and age 16.51 (±0.61) years (follow-up 1 (FU1), N = 1185, 54.9% female). General empathic distress served as a significant moderator of alcohol use in perpetrators (F9, 493 = 17.978, p < 0.01), which was specific for males and FU1. Male perpetrators, who are generally less sensitive to distress, might thus be more vulnerable to alcohol abuse.

Multisystem Inflammatory Syndrome in Children and Kawasaki Disease: A Spectrum of Postinfectious Hyperinflammatory Disease.

Kawasaki disease and multisystem inflammatory syndrome in children are hyperinflammatory conditions that share similar emerging pathophysiology hypotheses, clinical features, treatment strategies, and outcomes. Although both conditions have key differences, growing evidence suggests that both conditions might be closely related on a larger spectrum of postinfectious autoimmune responses.

Joyful by nature: approaches to investigate the evolution and function of joy in non-human animals.

The nature and evolution of positive emotion is a major question remaining unanswered in science and philosophy. The study of feelings and emotions in humans and animals is dominated by discussion of affective states that have negative valence. Given the clinical and social significance of negative affect, such as depression, it is unsurprising that these emotions have received more attention from scientists. Compared to negative emotions, such as fear that leads to fleeing or avoidance, positive emotions are less likely to result in specific, identifiable, behaviours being expressed by an animal. This makes it particularly challenging to quantify and study positive affect. However, bursts of intense positive emotion (joy) are more likely to be accompanied by externally visible markers, like vocalisations or movement patterns, which make it more amenable to scientific study and more resilient to concerns about anthropomorphism. We define joy as intense, brief, and event-driven (i.e. a response to something), which permits investigation into how animals react to a variety of situations that would provoke joy in humans. This means that behavioural correlates of joy are measurable, either through newly discovered 'laughter' vocalisations, increases in play behaviour, or reactions to cognitive bias tests that can be used across species. There are a range of potential situations that cause joy in humans that have not been studied in other animals, such as whether animals feel joy on sunny days, when they accomplish a difficult feat, or when they are reunited with a familiar companion after a prolonged absence. Observations of species-specific calls and play behaviour can be combined with biometric markers and reactions to ambiguous stimuli in order to enable comparisons of affect between phylogenetically distant taxonomic groups. Identifying positive affect is also important for animal welfare because knowledge of positive emotional states would allow us to monitor animal well-being better. Additionally, measuring if phylogenetically and ecologically distant animals play more, laugh more, or act more optimistically after certain kinds of experiences will also provide insight into the mechanisms underlying the evolution of joy and other positive emotions, and potentially even into the evolution of consciousness.

The Role of Telemedicine for Evaluation and Management of Dizzy Patients: A Systematic Review.

OBJECTIVES: To conduct a scoping systematic review of the literature on the use of telemedicine to evaluate, diagnose, and manage patients with dizziness. DATA SOURCES: Web of Science, SCOPUS, and MEDLINE PubMed databases. STUDY SELECTION: The inclusion criteria included the following: pertaining to telemedicine and the evaluation, diagnosis, treatment, or management of dizziness. Exclusion criteria included the following: single-case studies, meta-analyses, and literature and systematic reviews. DATA EXTRACTION: Outcomes recorded for each article included the following: study type, patient population, telemedicine format, dizziness characteristics, level of evidence, and quality assessment. DATA SYNTHESIS: The search returned 15,408 articles, and a team of four screened the articles for inclusion criteria status. A total of 9 articles met the inclusion criteria and were included for review. Of the nine articles, four were randomized clinical trials, three were prospective cohort studies, and two were qualitative studies. The telemedicine format was synchronous in three studies and asynchronous in six studies. Two of the studies involved acute dizziness only, four involved chronic dizziness only, one involved both acute and chronic dizziness, and two did not specify dizziness type. Six of the studies included the diagnosis of dizziness, two involved the evaluation of dizziness, and three involved treatment/management. Some of the reported benefits of telemedicine for dizziness patients included cost savings, convenience, high patient satisfaction, and improvement in dizziness symptoms. Limitations included access to telemedicine technology, Internet connectivity, and dizziness symptoms interfering with the telemedicine application. CONCLUSIONS: Few studies investigate the evaluation, diagnosis, or management of dizziness using telemedicine. The lack of protocols and standards of care for telemedicine evaluation of dizzy patients creates some challenges in care delivery; however, these reviewed studies provide examples of the breadth of care that has been provided remotely.
