Obesity in children and adolescents
BACKGROUND:The obesity epidemic in the United States affects not only adults, but children and adolescents. SOURCES OF MATERIAL/UNASSIGNED:An extensive review of the literature including 85 articles has been completed with the aim of providing the most current definitions and recommendations for this chronic condition. ABSTACT OF FINDINGS/UNASSIGNED:This article reviews the definition of pediatric obesity, the increasing prevalence of obesity in children and adolescents, genetic and environmental risk factors, as well as the unique aspects and implications of this condition and its associated comorbidities for this population in comparison to adults. Current management recommendations are also discussed which include Intensive Health Behavioral and Lifestyle Treatment (IHBLT), metabolic surgery, and pharmacologic therapy including glucago-like peptide-1 receptor agonists (GLP-1RAs). CONCLUSION/CONCLUSIONS:Childhood obesity is a unique condition in its progression and management requirements, and should be approached with a focus on prevention as well as on the high-risk individual.

Beyond the Bed: What Clinical and Non-clinical Factors Drive Length of Stay in Pediatric Psychiatry?
BackgroundRates of psychiatric disorders and related hospitalizations among youth in the United States have risen substantially over recent decades. Despite evidence supporting outpatient care, fewer than half of youth receive treatment. When outpatient management is insufficient, inpatient psychiatric hospitalization is required, though it is costly, disruptive, and limited in availability. Prior research on predictors of inpatient length of stay has been dated and heterogenous, highlighting the need to identify current clinical and non-clinical factors associated with prolonged stays among youth populations.MethodThis IRB-approved retrospective study reviewed the medical records of 1,101 child and adolescent patients admitted to an inpatient psychiatric unit between June 1, 2018, and November 30, 2021. Baseline sociodemographic and clinical data were collected, and LOS was categorized into three groups: below-average (0-6 days), average (7-14 days), and above-average (15+ days). Comparative statistics were performed, and linear regression was used to identify independent predictors of LOS.ResultsThe average LOS was 10.5 days. Significant predictors of prolonged LOS included public insurance, admission for psychosis or suicide attempt, involvement of child protective services, number of prior hospitalizations, and number of medications prior to admission.ConclusionProlonged LOS in psychiatrically hospitalized youth is associated with specific clinical and non-clinical factors. Identifying these predictors at admission can guide treatment planning and set realistic expectations for families. Further research is required to validate these findings and explore the impact of LOS on treatment outcomes.

A null findings study: graph theoretical analysis of the fetal functional connectome shows no relationships with future autistic traits
Autism spectrum disorder (ASD) is a neurodevelopmental condition, with ex vivo studies suggesting its neurobiological origin as early as the first and second trimester of pregnancy. Functional MRI studies using graph-theoretical approaches have isolated features in the global connectome architecture that distinguish toddlers with ASD from their typically developing peers. Additionally, functional connectivity patterns in the infant brain have shown to be predictive of later ASD diagnosis. An important yet unexplored question in the literature is whether graph-theoretical differences are evident prior to infancy, in the brain of fetuses who will later exhibit ASD traits in early childhood. In this study, we address this question using a sample of 88 children with both quality-assured fetal brain resting-state functional MRI data and standardized parent assessment of ASD traits including social-emotional and social communication skills and repetitive and restricted behaviors at age 3. Multiple regression analyses revealed no significant associations between fetal global graph features (e.g., network segregation, integration, and small-world architecture) and ASD traits at age 3 (p's > 0.1). Therefore, our findings do not provide support for prenatal emergence of global topographical differences of brain functional organization in fetuses who later develop ASD traits. However, this does not rule out the possibility of other neural signatures in the fetal functional connectome that may predict autistic traits and future ASD diagnosis.

Maternal Milk Allopregnanolone May Buffer Negative Associations Between Maternal Postpartum Psychological Distress and Infant Regulatory Capacity
Maternal psychological distress during pregnancy and the early postpartum period is a risk factor for dysregulated affective and regulatory function in young infants. Animal models suggest that perinatal stress may alter offspring development via allopregnanolone (ALLO) exposure. For example, variations in placentally derived ALLO in preterm infants have been linked with altered fetal neurodevelopment. However, no studies have investigated naturalistic variations in ALLO concentrations in maternal milk as a potential moderator of associations between maternal distress and infant temperament during the postnatal period. The current study assesses associations among ALLO concentrations in human milk, maternal psychological distress, and infant temperament in 81 mother-infant dyads (31 females) measured at approximately 6.5 months postpartum (M = 6.55 months, range = 5.5-8 months). Results indicated that human milk ALLO concentration moderated effects of maternal psychological distress on infant regulatory capacity. Specifically, there was a negative association between maternal psychological distress and regulatory capacity in infants of mothers with below-mean ALLO concentrations, but not in infants of mothers with above-mean ALLO concentrations. However, there were no effects of ALLO on infant negative affect or surgency/positive affect. This study provides some of the first preliminary evidence that ALLO concentrations in human milk may moderate associations between maternal psychological distress and infant regulatory capacity.

Devaluation of response-produced safety signals reveals circuits for goal-directed versus habitual avoidance in dorsal striatum
Active avoidance responses (ARs) are instrumental behaviors that prevent harm. Adaptive ARs may contribute to active coping, whereas maladaptive avoidance habits are implicated in anxiety and obsessive-compulsive disorders. The AR learning mechanism has remained elusive, as successful avoidance trials produce no obvious reinforcer. We used a novel outcome-devaluation procedure in rats to show that ARs are positively reinforced by response-produced feedback cues that develop into safety signals during training. Males were sensitive to feedback devaluation after moderate training, but not overtraining, consistent with a transition from goal-directed to habitual avoidance. Using chemogenetics and feedback devaluation, we also show that goal-directed vs. habitual ARs depend on dorsomedial vs. dorsolateral striatum, suggesting a significant overlap between the mechanisms of avoidance and rewarded instrumental behavior. Females were insensitive to feedbackdevaluation due to a remarkable context-dependence of counterconditioning. However, degrading the contingency between avoidance and feedback suggests that both sexes rely on safety signals to perform goal-directed ARs.

A double-blind, placebo-controlled, multi-crossover trial of treatment with a chemokine antagonist for knee osteoarthritis pain
Osteoarthritis, especially knee osteoarthritis, is a leading cause of disability and reduced quality of life. The etiology of pain in osteoarthritis is multifactorial, and one promising potential treatment approach involves targeting chemokine systems. The present study was a phase 2, multisite, multiperiod randomized crossover trial of CNTX-6970, a small molecule and selective oral cytokine chemokine receptor type 2 (CCR2) and CCR5 antagonist, in patients with painful knee osteoarthritis (OA). It represents the first trial performed within the National Institutes of Health's Early Phase Pain Investigation Clinical Network. The primary objectives were to evaluate the safety and efficacy of CNTX-6970, relative to placebo, for the treatment of moderate to severe pain related to knee OA. A total of 55 participants were randomized in this multiperiod crossover trial. Linear mixed effects models revealed no significant pain-related benefits of active medication; indeed, trial participants reported slightly higher knee pain intensity when taking the novel chemokine antagonist CNTX-6970 than when taking placebo. In addition, biomarker analysis revealed notably higher level of serum monocyte chemoattractant protein 1 levels when patients were on CNTX-6970 compared to placebo. Overall, although CNTX-6970 was safe and relatively well-tolerated, pharmacologic blockade of specific chemokine receptors with this compound was not effective in reducing moderate-to-severe knee osteoarthritis pain.

Tolerance and Tachyphylaxis to Medications for Attention-Deficit/Hyperactivity Disorder (ADHD): A Systematic Review of Empirical Studies
BACKGROUND AND OBJECTIVE/OBJECTIVE:Individuals with attention-deficit/hyperactivity disorder, their families and clinicians may report worsening symptoms despite compliant use of medication, suggesting potential tolerance, but evidence remains conflicting. Some studies have also suggested tachyphylaxis, or acute tolerance, though research is limited. We conducted the first systematic review of empirical studies focussing on tolerance/tachyphylaxis to attention-deficit/hyperactivity disorder medication to clarify their potential clinical relevance. METHODS:As registered on PROSPERO (CRD42024594759), we searched PubMed, OVID (including PsychInfo and MEDLINE) and Web of Knowledge up to 1 September, 2024, and assessed the risk of bias using National Institutes of Health quality assessment tools. RESULTS:The identified 17 studies were either interventional or observational, and varied greatly in design and duration. Four investigated tachyphylaxis, nine tolerance to the subjective and behavioural effects, and four tolerance to cardiovascular effects. We found preliminary evidence of tachyphylaxis to the affective or behavioural effects of stimulants, as well as tolerance to the subjective effects of d-amphetamine, such as drug liking and excitation, in neurotypical volunteers in the short term. Conversely, there was little or no evidence for tolerance to the therapeutic or cardiovascular effects of attention-deficit/hyperactivity disorder medication in clinical settings in the longer term. Quality was rated as low in most studies because of small sample sizes and methodological limitations. CONCLUSIONS:Overall, these results do not support the hypothesis that tolerance commonly develops to the therapeutic effects of attention-deficit/hyperactivity disorder medication, although robustly designed longitudinal studies are needed to provide more conclusive evidence. Clinicians may consider other potential explanations for reduced therapeutic effects over time, including natural fluctuations of symptoms, limited compliance, life events and co-occurrent mental health conditions.

The International Guideline for the Definition, Classification, Diagnosis and Management of Urticaria
This update and revision of the international guideline for urticaria was developed in accordance with the methods recommended by Cochrane and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) working group. It is an initiative of the Global Allergy and Asthma Excellence Network (GA2LEN) and its Urticaria and Angioedema Centers of Reference and Excellence (UCAREs and ACAREs), with the participation of 210 delegates from 107 national and international societies, from 59 countries. The consensus conference was held on December 6th, 2024. This guideline was acknowledged and accepted by the European Union of Medical Specialists (UEMS). Urticaria is a frequent, mast cell-driven disease, defined by a rapid appearance of wheals, angioedema, or both. The lifetime prevalence of acute urticaria is estimated to be approximately 20%. Chronic urticaria, categorized as either chronic spontaneous urticaria or chronic inducible urticaria, is disabling, impairs quality of life, and affects performance at work and school, however, novel therapies are available. This updated version of the international guideline for urticaria covers the definition and classification of urticaria and outlines expert-guided and evidence-based diagnostic and therapeutic approaches for the different subtypes of urticaria.
