Late to Extubate? Risk Factors and Associations for Delayed Extubation after Adult Cervical Deformity Corrective Surgery
STUDY DESIGN/METHODS:Retrospective cohort study. OBJECTIVE:Due to proximity of the surgical site to important respiratory structures, patients may undergo delayed extubation after adult cervical deformity (ACD) surgery to manage postoperative airway edema/obstruction. Herein, we evaluate relevant relationships with delayed extubation. SUMMARY OF BACKGROUND DATA/BACKGROUND:Delayed extubation is an underreported perioperative occurrence, with only a few studies conducting case-by-case reviews of prolonged intubation. METHODS:Operative ACD patients with baseline (BL) were grouped based on whether they experienced delayed extubation (DE), or leaving the OR while still intubated, versus those who were extubated successfully in the OR (non-DE). Means comparison and regression analyses identified predictors of delayed extubation and associations with peri-operative complications and outcomes. RESULTS:82 patients met inclusion criteria (mean age 62.4±13.0 y, 52.4% female, Edmonton frailty score: 5.10±2.97, ACFI score: 0.30±0.16, CCI: 1.41±1.73). 14 patients left the OR intubated, and 1(1.2%) required reintubation. DE cohort demonstrated greater Edmonton frailty scores (P=0.017) and smoking histories (P=0.031). Intraoperatively, there was a significant difference EBL (P=0.021) and rate of transfusions (DE: 27.3% v non-DE: 4.8%, P=0.12). Upper instrumented vertebra (UIV) was not associated with DE, while lower LIV increased the likelihood of DE (OR 1.1, P=0.029). Post-operatively, as expected, there was a significant difference in rate of SICU admissions (DE: 90.9% v. non-DE: 49.2%, P=0.01), although no significant differences in LOS. Greater cSVA and MGS correction from baseline was associated with increased likelihood of delayed extubation (OR 1.1, CI 95% 1.05-1.17, P<.001; OR 1.14, CI 95% 1.05-1.24, P=0.003). Furthermore, delayed extubation was a significant predictor of increased VR-Physical Component Scores (P=0.013) at 6W, and DE cohort demonstrated significantly higher VR-PCS and VR-MCS Scores at 6W (P=0.01, both). CONCLUSIONS:Baseline frailty and larger radiographic correction can be associated with delayed extubation, which can impact quality of life perioperatively. Considerations like minimizing intraoperative blood loss and degree of correction could minimize delayed extubation.

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.

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.

Bridging Perspectives: Clinician-Adolescent Agreement on Psychopathological Severity in the European MILESTONE Cohort
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.

Insurance-based Disparities in Pediatric Psychiatric Hospitalizations from 2018 to 2021: Examining Mental Health Outcomes among Medicaid and Commercially Insured Youth
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.

The role of negative affectivity in the developmental pathway linking perinatal complications to behavioral and emotional problems in children
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

Leveraging clinical sleep data across multiple pediatric cohorts for insights into neurodevelopment: the retrospective analysis of sleep in Pediatric (RASP) cohorts study
Sleep disturbances are prominent across neurodevelopmental disorders (NDDs) and may reflect specific abnormalities in brain development and function. Overnight polysomnography (PSG) allows for detailed investigation of sleep architecture, offering a unique window into neurocircuit function. Analysis of existing pediatric PSGs from clinical studies could enhance the availability of sleep studies in pediatric patients with NDDs towards a better understanding of mechanisms underlying abnormal development in NDDs. Here, we introduce and characterize a retrospective collection of 1527 clinical pediatric overnight PSGs across five different sites. We first developed an automated stager trained on independent pediatric sleep data, which yielded better performance compared to a generic stager trained primarily on adults. Using consistent staging across cohorts, we derived a panel of EEG micro-architectural features. This unbiased approach replicated broad trajectories previously described in typically developing sleep architecture. Further, we found sleep architecture disruptions in children with Down's Syndrome (DS) that were consistent across independent cohorts. Finally, we built and evaluated a model to predict age from sleep EEG metrics, which recapitulated our previous findings of younger predicted brain age in children with DS. Altogether, by creating a resource pooled from existing clinical data we expanded the available datasets and computational resources to study sleep in pediatric populations, specifically towards a better understanding of sleep in NDDs. This Retrospective Analysis of Sleep in Pediatric (RASP) cohorts dataset, including staging annotation derived from our automated stager, is deposited at https://sleepdata.org/datasets/rasp.

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.

Associations of neighborhood deprivation and household income during pregnancy on child externalizing and internalizing problems
Socioeconomic disadvantage has been established as a key risk factor for adverse child behavioral outcomes. Understanding how individual components of socioeconomic status (SES) interact with each other can elucidate protective factors and inform interventions and policies to promote positive developmental outcomes. This study examined the interactive effects of prenatal household income and neighborhood deprivation on child externalizing and internalizing problems (N = 793; M

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.
