BACKGROUND:Research demonstrates the effectiveness of evidence-based psychological treatment adjunctive to pharmacotherapy for reducing mood symptoms in bipolar disorder. However, access to these treatments is limited, and innovative strategies are needed to ensure that more patients with bipolar disorder receive the gold-standard treatments that may help them achieve wellness. "Stepped care" models of psychological service delivery represent one potential solution to this problem of treatment access. Under a stepped care model, patients are assigned the minimum necessary psychological treatment for symptom improvement. This typically means that patients who are experiencing more symptoms are assigned to a treatment of greater intensity (e.g., weekly individual therapy) whereas patients who are experiencing fewer symptoms are assigned to a treatment of relatively lesser intensity (e.g., biweekly group therapy). Stepped care models are dynamic, meaning that the level of treatment can be modified depending on the patient's response. Stepped care models have been explored in other clinical populations but require further exploration in bipolar disorder. METHODS:Members of the Psychological Interventions Task Force for the International Society of Bipolar Disorders conducted a narrative review of stepped care models and their application to bipolar disorder. RESULTS:We found evidence that stepped care models are useful approaches to delivering psychosocial treatments for bipolar disorder. We discuss several contextual factors in executing stepped care models in this population (i.e., cultural and pediatric applications), as well as share an example of a stepped care model-Focused Integrated Team-based Treatment for Bipolar Disorder (FITT-BD)-that is currently being evaluated in an academic medical center. CONCLUSION/CONCLUSIONS:Further research is warranted to develop and assess robust stepped care models to determine whether they can improve access to treatment of bipolar disorder while not sacrificing outcomes.

The piriform cortex (PCx), commonly considered to be the primary olfactory sensory cortex, differs from other mammalian sensory cortices by not displaying a stimulus-specific spatial organization but rather displaying widely distributed odor-evoked activity. However, there is evidence of a PCx spatial organization based on output neuron targeting. Here, we performed double-labeled retrograde tracing to reveal neuronal populations of PCx output neurons that project to two regions affiliated with different behavioral significance, the basolateral amygdala (BLA) and lateral orbitofrontal (LO) cortex networks. We found that PCx neurons projecting to BLA and LO are distinct in spatial distribution with minimal overlap, supporting the hypothesis that while odor input is distributed randomly across the PCx, PCx output neurons are organized into target-specific neuronal populations that potentially serve as functional units for odor encoding and odor-guided behavior.

OBJECTIVE:Pediatric primary care (PPC) offers an ideal platform for integrating evidence-based programs (EBPs) to enhance early relational health (ERH). However, implementing such integration faces several challenges. This study uses quantitative and qualitative data to identify the barriers, facilitators, and strategies for implementing ERH-focused EBPs in PPC. METHODS:Using the Consolidated Framework for Implementation Research framework, we conducted a survey and focus groups with PPC personnel recruited through nationwide networks. The survey measured clinic readiness (i.e., challenges, resources, and needs) for integration and examined its associations with personnel roles and clinic characteristics using nested ANOVAs and multilevel regressions. Focus groups further probed potential strategies and were coded using thematic analysis. RESULTS:126 PPC personnel from 44 clinics completed the survey, and 18 participated in five focus groups. Clinics had strong leadership support for integrated services and high utilization of program resources and implementation practices, yet notable challenges in structural and human resources existed. Clinic staff perceived higher readiness for integration than other personnel roles. Lower-percent Medicaid eligible patients and urbanicity were associated with higher readiness, while academic affiliation showed both positive and negative associations. Promoting culturally responsive care, fostering team cohesion, utilizing standardized implementation processes, adopting flexible delivery and collaborative models, and partnering with local communities were key strategies for integrating EBPs. CONCLUSIONS:The findings can help PPC clinics more effectively integrate one or multiple EBPs into routine care and can inform ways to sustain such integrated services to optimize population-level reach and positive impacts on child and family well-being.

OBJECTIVES/OBJECTIVE:Adolescents transitioning from child and adolescent mental health services (CAMHS) to adult mental health services (AMHS) may face challenges in accurately identifying and reporting their mental health symptoms, often leading to discrepancies between clinician and patient evaluations. Using data from the MILESTONE project, this study aims to assess clinician-adolescent concordance over 24 months and identify domains of psychopathology with the highest disparities. METHODS:Participants were assessed at baseline, 9, 15, and 24 months using the Health of the Nation Outcome Scales for Children and Adolescents (HoNOSCA) scale and were categorized in four diagnostic groups. Hierarchical cluster analysis identified symptom-based subgroups of patients based on clinician and patient-rated HoNOSCA scores. Concordance was evaluated through multilevel linear regression models, while Bland-Altman plots examined agreement between scores across time points. RESULTS:Two clusters of patients were identified: one characterized by lower severity and greater prevalence, the other by higher complexity and fewer individuals. Clinician-patient concordance increased over time, rising from 77% to 83% by the second time point and stabilizing. Concordance varied across diagnostic categories, with anxiety showing the highest agreement and ADHD the lowest. CONCLUSIONS:Improved communication, psychoeducation, and tailored interventions may facilitate greater patient-clinician alignment, thereby supporting more favorable outcomes during this critical developmental period.

Although temperamental negative affectivity has been identified as a developmental mechanism mediating the link between perinatal risk and internalizing problems in early childhood, its role in predicting broader behavioral and emotional problems across childhood remains understudied. We examined the longitudinal relations among perinatal complications (i.e., prenatal maternal depression and cardiometabolic complications, preterm birth, and low birth weight), children's negative affectivity (M

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.

Insurance type is a key indicator of structural vulnerability in pediatric mental health care and may be associated with differences in psychiatric presentation, treatment course, and diagnosis among hospitalized youth, particularly Black and Hispanic/Latino children insured by Medicaid. Despite these inequities, their impact remains understudied among psychiatrically hospitalized pediatric populations. This retrospective study analyzed 1,101 child and adolescent psychiatric patients admitted to an urban psychiatric hospital between June 2018 and November 2021. Clinical presentation, psychiatric history, treatment course, and discharge diagnoses were compared between patients' insurance by Medicaid (72%) and those with commercial insurance (28%). Compared with commercially insured patients, children and adolescents with Medicaid were more likely to be Black or Hispanic/Latino and had higher rates of trauma exposure, prior psychiatric emergency visits, and higher rates of attention-deficit/hyperactivity disorder (ADHD), impulsive/behavioral disorders, and developmental/intellectual disorders. They were more frequently admitted for aggression-related crises, more likely to receive emergency injectable medications for agitation, and had longer hospital stays. Commercially insured patients had higher rates of anxiety disorders and suicide attempt related admissions. These findings suggest children and adolescents with Medicaid who required psychiatric hospitalization had greater severity of psychosocial histories and higher-acuity inpatient courses, highlighting how structural inequities reflected by insurance type, may shape differing psychiatric treatment pathways, underscoring the need for equity-oriented interventions, particularly during periods of healthcare system strains.

INTRODUCTION/BACKGROUND:The long-standing cholinergic hypothesis posits that cholinergic signaling is uniformly deficient in Alzheimer's disease (AD) and Down syndrome (DS). We tested the hypothesis that this deficiency occurs primarily late in disease, while early stages involve excessive cholinergic signaling, with distinct implications for memory. METHODS:Tg2576 (AD model; n = 38), Ts65Dn (DS model; n = 14), and wild-type (WT; n = 17) mice at young (3 to 4 months) and old (>14 months) ages received treatments to reduce cholinergic signaling (medial septum chemogenetic inhibition, muscarinic antagonist scopolamine) or enhance it (acetylcholinesterase inhibitor donepezil). Memory assessments used novel object recognition. RESULTS:Anticholinergic manipulations restored memory in young Tg2576 and Ts65Dn mice but impaired age-matched WT mice. Conversely, donepezil improved the memory of old Tg2576, Ts65Dn, and WT but not young Tg2576 and Ts65Dn animals. DISCUSSION/CONCLUSIONS:These findings refine and challenge the cholinergic hypothesis, revealing for the first time a functional shift from cholinergic hyperactivity driving early cognitive impairment to late-stage degeneration requiring enhancement.
