RESUMEN

BACKGROUND: Police activity in emergency medical settings has been shown to complicate the care of patients and impact patient-provider relationships. Recent scholarship has called for clear hospital policy outlining the terms of police access to patients and the role of clinicians. Despite regular contact between trauma surgeons and police, research on the impact of police activity on trauma care has been limited. METHODS: Semi-structured interviews were conducted with attending trauma surgeons and general surgery residents (N = 13) at 3 urban hospitals about their interactions with police in clinical settings. Participants were recruited using snowball sampling. Interviews were audio-recorded, transcribed, and analyzed for recurrent themes using an iterative grounded theory process. RESULTS: Participants reported routine contact with police that required active negotiation of the scope of clinical and police authority in the hospital. These negotiations were shaped by prior experiences, perceptions of police, officer behavior, and institutional culture. Surgeons felt compelled to advocate for patients, but reported intimidation in moments of conflict. Participants noted uncertainty around the legal dimensions of their relationship to police and a lack of universal guidance on appropriate responses. DISCUSSION: This data points to the need for improvements in both policy and workflow to regulate and reduce the burden of these interactions and protect clinicians' priorities from being subordinated to those of police. Further research is needed to understand how police presence impacts patient outcomes, and to guide best practices for regulating and mitigating potential negative impact.

RESUMEN

BACKGROUND: Substance use during the perinatal period (i.e., pregnancy through the first year postpartum) can pose significant maternal and infant health risks. However, access to lifesaving medications and standard care remains low for perinatal persons who use substances. This lack of substance use disorder treatment access stems from fragmented services, stigma, and social determinants of health-related barriers that could be addressed using patient navigators. This systematic review describes patient navigation models of care for perinatal people who use substances and associated outcomes. METHODS: We conducted a structured search of peer-reviewed, US-focused, English- or Spanish-language articles from 2000 to 2023 focused on 1) patient navigation, 2) prenatal and postpartum care, and 3) substance use treatment programs using PubMed, Scopus, PsycINFO, and CINAHL databases. RESULTS: After meeting eligibility criteria, 17 studies were included in this review. The majority (n=8) described outpatient patient navigation programs, with notable hospital (n=4) and residential (n=3) programs. Patient navigation was associated with reduced maternal substance use, increased receipt of services, and improved maternal and neonatal health. Findings were mixed for engagement in substance use disorder treatment and child custody outcomes. Programs that co-located care, engaged patients across the perinatal period, and worked to build trust and communication with family members and service providers were particularly successful. CONCLUSION: Patient navigation may be a promising strategy for improving maternal and infant health outcomes among perinatal persons who use substances. More experimental research is needed to test the effect of patient navigation programs for perinatal persons who use substances compared to other models of care.

RESUMEN

OBJECTIVE: Childhood trauma may contribute to poor lifelong health in part through programming of the HPA-axis response to future life stressors. To date, empirical evidence shows an association of childhood trauma with dysregulation of the HPA-axis and blunted cortisol reactivity to acute stressors. Here, we conduct an initial examination of childhood trauma as a moderator of changes over time in perceived stress levels and HPA-axis response to a major chronic stressor in adulthood. METHODS: Participants were 83 maternal caregivers of children newly diagnosed with cancer who completed the Childhood Trauma Questionnaire (CTQ), and who, over the year following their child's cancer diagnosis, had hair samples collected up to 7 times for the assessment of cortisol and completed monthly measures of perceived stress. RESULTS: CTQ scores were in the expected range for a community sample and associated with changes in perceived stress and cortisol concentration over time (γ =.003, p =.002; γ = -.0004, p =.008, respectively) independently of age, education, treatment intensity and randomization to stress management intervention. Maternal caregivers who endorsed lower childhood trauma showed a steeper decline in perceived stress and a larger increase in cortisol levels across the year than caregivers who recalled more childhood trauma. CONCLUSIONS: Findings extend animal models and studies that examine cortisol reactivity to acute stressors and suggest that childhood trauma may program a phenotype that is more psychologically reactive but shows a blunted HPA-axis response to chronic stress. While adaptive in the short-term, this early life programming may incur long-term costs for health. Further work is warranted to examine this possibility.

RESUMEN

OBJECTIVE: We systematically reviewed the literature to assess the association between use of alcohol protective behavioral strategies (PBS) and young adult heavy drinking and alcohol-related consequences. METHOD: We followed the preferred reporting items for systematic review and meta-analysis guidelines to select and review research studies that were comprised of a sample of young adults ages 18-26, included PBS derived from one of 10 validated scales as an independent variable, measured heavy alcohol use or alcohol consequences as the dependent variable, and tested the direct association between the two. Studies were gathered via PubMed, Scopus, Cumulative Index to Nursing and Allied Health Literature, APA PsycInfo, and Global Health. All identified study records underwent a two-step screening process and risk of bias assessment. RESULTS: Data were extracted from 94 studies that met inclusion criteria; 16 studies (17%) examined associations with heavy alcohol use and 91 studies (97%) tested effects of PBS on alcohol consequences. All studies that measured a total effect of PBS use (summations across all strategies) found significant negative associations with heavy alcohol use and 91% were negatively associated with alcohol consequences. Most studies that examined subscales of PBS found at least one significant, negative relation with heavy alcohol use (73%) and alcohol-related consequences (78%), though effects varied across type of subscale (e.g., manner of drinking). CONCLUSIONS: Our results support the use of PBS to address heavy alcohol consumption and related harms among young adults. Opportunities for refinement of current PBS in preventive interventions are discussed. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

RESUMEN

BACKGROUND/OBJECTIVES: To determine long-term outcomes of patients referred with proliferative diabetic retinopathy (PDR) from diabetic eye screening programmes (DESP) to tertiary care centres in the United Kingdom (UK). METHODS: Retrospective multicentre study of patients referred from two DESPs in the UK over a 36-month period (2007-9) and followed-up for 10 years. Critical outcomes included severe vision loss (SVL) and the need for vitrectomy. Other outcomes assessed included moderate vision loss (MVL), and patient survival time. Univariate and multiple variable Cox proportional hazards regressions were used to analyse survival outcomes. RESULTS: 212 eyes of 150 patients were referred with a diagnosis of PDR. 109 eyes of 72 patients were confirmed to have active PDR and included in the study. 61% of patients had low-risk PDR, while 39% exhibited high-risk features in at least one eye. Eight (7.3%) eyes developed SVL and 16 (14.7%) MVL during follow up. Vitrectomy was required in 24% (95% CI: 15 to 31%) of all PDR eyes and was most commonly performed for vitreous haemorrhage (65%). The 10-year survival in all PDR patients was 76% (95% CI: 63 to 85%) with the mean time to death for all deceased patients being 5.4 ± 3.6 years. On multivariable analysis, only age was found to have a significant association with the survival of patients with PDR. CONCLUSIONS: During the 10 year follow up SVL was uncommon, but MVL occurred in almost one-fifth of the eyes. Approximately 1 in 4 eyes required vitrectomy, highlighting its significance in patient management.

RESUMEN

Clinical perfectionism, self-esteem, mood intolerance, and interpersonal difficulties are associated with eating disorder symptoms in clinical samples. The aim of the current study was to test a model including clinical perfectionism, self-esteem, mood intolerance, and interpersonal difficulties to understand eating disorder symptoms in an adolescent community sample. Adolescents (N = 446, M age = 16.25 years, SD = 1.64; 74.2% female) completed measures of clinical perfectionism, self-esteem, mood intolerance, interpersonal difficulties, and eating disorder symptoms. Path analysis indicated clinical perfectionism, self-esteem, mood intolerance, and interpersonal difficulties were all directly associated with symptoms of eating disorders, and that clinical perfectionism was indirectly associated with eating disorders through self-esteem, mood intolerance, and interpersonal difficulties. The results indicate the cognitive-behavioural model of eating disorders can be applied to adolescents in the community with symptoms of eating disorders. Directional causality between constructs should be established to understand whether increased clinical perfectionism, and reduced self-esteem, mood intolerance, and interpersonal difficulties are vulnerabilities to the development and maintenance of eating disorders.

RESUMEN

Precision health refers to the use of individualised biomarkers or predictive models to provide more tailored information about an individual's likely prognosis. For child psychiatry and psychology, we argue that this approach requires a focus on neurocognitive measures collected in early life and at large scale. However, the large sample sizes necessary to uncover individual-level predictors are currently rare in studies of neurodevelopmental conditions in early childhood. We recommend two strategies going forward: first, including neurocognitive measures in new national cohort studies, and second, synergising measures and data across currently funded longitudinal studies.

RESUMEN

BACKGROUND: Vaccination during pregnancy reduces the incidence of infections and their associated adverse outcomes in both mothers and infants. The American College of Obstetricians and Gynecologists has recommended influenza and Tdap vaccination during pregnancy since 2004 and 2013, respectively. Several studies have examined disparities in vaccination rates during pregnancy by race/ethnicity. However, none have included American Indians/Alaska Natives as a specific racial/ethnic group on a national level. Current literature suggests that American Indian/Alaska Native infants experience increased morbidity and mortality from both influenza and pertussis infections compared with most other groups in the United States. OBJECTIVE: This study aimed to evaluate the uptake of influenza and Tdap vaccinations during pregnancy by race/ethnicity, with a specific focus on American Indian/Alaska Native people. STUDY DESIGN: This cross-sectional study used data from the Pregnancy Risk Assessment Monitoring System. Comparisons of vaccine uptake across racial/ethnic groups (American Indian/Alaska Native, Asian, non-Hispanic Black, non-Hispanic White, Hispanic, and "None of the above") were evaluated using weighted logistic regression analyses to estimate prevalence odds ratios with 95% confidence intervals. Models were adjusted for maternal age, parity, maternal education, marital status, payment method at delivery, prenatal care in first trimester, maternal smoking status, Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) participation, and receipt of influenza vaccine reported by a health care provider. RESULTS: For both vaccines, Asian respondents had the highest uptake (influenza, 70.1%; Tdap, 68.2%), whereas Black respondents reported the lowest uptake (influenza, 44.4%; Tdap, 57.9%). For the influenza vaccine, American Indian/Alaska Native respondents demonstrated a higher uptake compared with White respondents, and the magnitude of difference increased markedly after adjusting for respondent characteristics (adjusted odds ratio, 1.74; 95% confidence interval, 1.58-1.90). In the unadjusted analyses, Black individuals reported influenza vaccination at approximately half the rate of their White counterparts during pregnancy. This effect was attenuated but remained lower after adjustment for respondent characteristics (adjusted odds ratio, 0.73; 95% confidence interval, 0.70-0.76). For the Tdap vaccine, American Indian/Alaska Native respondents reported lower uptake than White respondents; however, this difference disappeared when adjusted for respondent characteristics (adjusted odds ratio, 0.99; 95% confidence interval, 0.83-1.19). Asian and Hispanic respondents displayed a similar uptake compared with their White counterparts for both vaccines. CONCLUSION: Our findings indicate that there are racial/ethnic disparities in influenza and Tdap vaccination rates among pregnant individuals in the United States. Demonstration of increased uptake among American Indian/Alaska Native people in the crude analysis may reflect the success of various public health interventions through Tribal and Indian Health Service hospitals. Nonetheless, vaccination status during pregnancy remains seriously below national guideline recommendations. Greater measures must be taken to support preventative care in marginalized populations, with particular emphasis on community-driven solutions rooted in justice.

RESUMEN

BACKGROUND: There is a strong association between perfectionism and eating disorders. In a cognitive-behavioural model of compulsive exercise it has been suggested there are reciprocal associations between perfectionism, eating disorder pathology, and compulsive exercise. No study has examined if there is an indirect association between perfectionism and compulsive exercise through eating disorder pathology, which would inform a preliminary understanding of the cognitive-behavioural model of compulsive exercise. METHODS: The sample included 301 adolescent females diagnosed with eating disorders (age M = 14.89, SD = 0.85, range 13-17). We tested models of direct and indirect associations of compulsive exercise in the relationship between perfectionism and eating disorder pathology, and direct and indirect associations of eating disorder pathology in the relationship between compulsive exercise and perfectionism. RESULTS: Perfectionism was directly associated with eating disorder pathology and compulsive exercise. Perfectionism was indirectly associated with eating disorder pathology through compulsive exercise. Perfectionism also had an indirect association with compulsive exercise through eating disorder pathology. DISCUSSION: The findings suggest it would be useful for future prospective research to examine the cognitive-behavioural model of compulsive exercise in adolescents with eating disorders. Compulsive exercise and perfectionism may be useful targets for future research to improve eating disorder treatment. Level of evidence Level V: Opinions of respected authorities, based on descriptive studies, narrative reviews, clinical experience, or reports of expert committees.

RESUMEN

Measures of early neuro-cognitive development that are suitable for use in low-resource settings are needed to enable studies of the effects of early adversity on the developing brain in a global context. These measures should have high acquisition rates and good face and construct validity. Here, we investigated the feasibility of a naturalistic electroencephalography (EEG) paradigm in a low-resource context during childhood. Additionally, we examined the sensitivity of periodic and aperiodic EEG metrics to social and non-social stimuli. We recorded simultaneous 20-channel EEG and eye-tracking in 72 children aged 4-12 years (45 females) while they watched videos of women singing nursery rhymes and moving toys, selected to represent familiar childhood experiences. These measures were part of a feasibility study that assessed the feasibility and acceptability of a follow-up data collection of the South African Safe Passage Study, which tracks environmental adversity and brain and cognitive development from before birth up until childhood. We examined whether data quantity and quality varied with child characteristics and the sensitivity of varying EEG metrics (canonical band power in the theta and alpha band and periodic and aperiodic features of the power spectra). We found that children who completed the EEG and eye-tracking assessment were, in general, representative of the full cohort. Data quantity was higher in children with greater visual attention to the stimuli. Out of the tested EEG metrics, periodic measures in the theta frequency range were most sensitive to condition differences, compared to alpha range measures and canonical and aperiodic EEG measures. Our results show that measuring EEG during ecologically valid social and non-social stimuli is feasible in low-resource settings, is feasible for most children, and produces robust indices of social brain function. This work provides preliminary support for testing longitudinal links between social brain function, environmental factors, and emerging behaviors.

RESUMEN

Synchronous excitatory discharges from the entorhinal cortex (EC) to the dentate gyrus (DG) generate fast and prominent patterns in the hilar local field potential (LFP), called dentate spikes (DSs). As sharp-wave ripples in CA1, DSs are more likely to occur in quiet behavioral states, when memory consolidation is thought to take place. However, their functions in mnemonic processes are yet to be elucidated. The classification of DSs into types 1 or 2 is determined by their origin in the lateral or medial EC, as revealed by current source density (CSD) analysis, which requires recordings from linear probes with multiple electrodes spanning the DG layers. To allow the investigation of the functional role of each DS type in recordings obtained from single electrodes and tetrodes, which are abundant in the field, we developed an unsupervised method using Gaussian mixture models to classify such events based on their waveforms. Our classification approach achieved high accuracies (> 80%) when validated in 8 mice with DG laminar profiles. The average CSDs, waveforms, rates, and widths of the DS types obtained through our method closely resembled those derived from the CSD-based classification. As an example of application, we used the technique to analyze single-electrode LFPs from apolipoprotein (apo) E3 and apoE4 knock-in mice. We observed that the latter group, which is a model for Alzheimer's disease, exhibited wider DSs of both types from a young age, with a larger effect size for DS type 2, likely reflecting early pathophysiological alterations in the EC-DG network, such as hyperactivity. In addition to the applicability of the method in expanding the study of DS types, our results show that their waveforms carry information about their origins, suggesting different underlying network dynamics and roles in memory processing.

RESUMEN

Climate change in northern latitudes is increasing the vulnerability of peatlands and the riparian transition zones between peatlands and upland forests (referred to as ecotones) to greater frequency of wildland fires. We examined early post-fire vegetation regeneration following the 2011 Utikuma complex fire (central Alberta, Canada). This study examined 779 peatlands and adjacent ecotones, covering an area of ~182 km2 . Based on the known regional fire history, peatlands that burned in 2011 were stratified into either long return interval (LRI) fire regimes of >80 years (i.e., no recorded prior fire history) or short fire return interval (SRI) of 55 years (i.e., within the boundary of a documented severe fire in 1956). Data from six multitemporal airborne lidar surveys were used to quantify trajectories of vegetation change for 8 years prior to and 8 years following the 2011 fire. To date, no studies have quantified the impacts of post-fire regeneration following short versus long return interval fires across this broad range of peatlands with variable environmental and post-fire successional trajectories. We found that SRI peatlands demonstrated more rapid vascular and shrub growth rates, especially in peatland centers, than LRI peatlands. Bogs and fens burned in 1956, and with little vascular vegetation (classified as "open peatlands") prior to the 2011 fire, experienced the greatest changes. These peatlands tended to transition to vascular/shrub forms following the SRI fire, while open LRI peatlands were not significantly different from pre-fire conditions. The results of this study suggest the emergence of a positive feedback, where areas experiencing SRI fires in southern boreal peatlands are expected to transition to forested vegetation forms. Along fen edges and within bog centers, SRI fires are expected to reduce local peatland groundwater moisture-holding capacity and promote favorable conditions for increased fire frequency and severity in the future.

RESUMEN

Almaatouq et al. propose an integrative experiment design space combined with large samples for scientific advancement. We argue recent innovative designs combining closed-loop experiment designs and Bayesian optimisation allow for integrative experiments at an individual level during a single session, circumventing the necessity for large samples. This method can be applied across disciplines, including developmental and clinical research.

RESUMEN

PURPOSE: To determine the most common indications for lateral extra-articular tenodesis (LET) augmentation of anterior cruciate ligament reconstruction (ACLR). METHODS: A systematic review of the literature was performed using Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We searched PubMed, Embase, Web of Science, and Cochrane Database of Systematic Reviews from 2000 to the present (June 2022). Studies that met the following criteria were included: patients of any age who underwent LET in addition to ACLR, studies reporting at least 1 indication for LET, and observational/randomized controlled trial study designs including prevalence of indications. Publications had to be reported in English and peer reviewed and to have originated in the United States or countries offering identical protocols and procedures. RESULTS: A total of 463 studies were identified from the initial search, 23 of which met inclusion criteria and were included in the review. Eight of the 23 studies (34.8%) used a modified Lemaire technique, seven (30.4%) used a MacIntosh modified by Arnold-Coker, and eight (34.8%) used other techniques to perform LET. A total of 2,125 patients (53% female, 47% male [3 studies did not report sex]) underwent ACLR augmented with LET. The indications along with prevalence were as follows: positive pivot shift test (grade ≥2) (19 of 23, 82.6%), revision ACLR (12 of 23, 52.2%), ligamentous laxity (11 of 23, 47.8%), general sports participation (11 of 23, 47.8%), age less than 25 years (8 of 23, 34.8%), high risk of graft failure (5 of 23, 21.7%), and positive Lachman test (4 of 23, 17.4%). CONCLUSIONS: Pivot shift grade ≥2 was the most common reason orthopaedic surgeons chose to add LET to ACLR, with revision ACLR, patient age <25, and general sports participation following closely behind. LEVEL OF EVIDENCE: Level I to IV, systematic review of studies.

RESUMEN

Many species have been intentionally introduced to new regions for their benefits. Some of these alien species cause damage, others do not (or at least have not yet). There are several approaches to address this problem: prohibit taxa that will cause damage, try to limit damages while preserving benefits, or promote taxa that are safe. In the present article, we unpack the safe list approach, which we define as "a list of taxa alien to the region of interest that are considered of sufficiently low risk of invasion and impact that the taxa can be widely used without concerns of negative impacts." We discuss the potential use of safe lists in the management of biological invasions; disentangle aspects related to the purpose, development, implementation, and impact of safe lists; and provide guidance for those considering to develop and implement such lists.

RESUMEN

BACKGROUND: Globally, the oldest old population is expected to triple by 2050. Hospitalization and malnutrition can result in progressive functional decline in older adults. Minimizing the impact of hospitalization on functional status in older adults has the potential to maintain independence, reduce health and social care costs, and maximize years in a healthy state. This study aimed to systematically review the literature to identify nutritional interventions that target physical function, body composition, and cognition in the older population (≥ 75 years). METHODS: A systematic review was conducted to evaluate the efficacy of nutritional interventions on physical function, body composition, and cognition in adults aged ≥ 75 years or mean age ≥80 years. Searches of PubMed (National Institutes of Health, National Library of Medicine), Scopus (Elsevier), EMBASE (Elsevier), Cumulative Index to Nursing and Allied Health Literature (CINAHL) with Full Text (EBSCOhost), and PsycInfo (EBSCOhost) were conducted. Screening, data extraction, and quality assessment were performed in duplicate and independently (CRD42022355984; https://www.crd.york.ac.uk/prospero/display_record.php?RecordID=355984). RESULTS: Of 8311 citations identified, 2939 duplicates were excluded. From 5372 citations, 189 articles underwent full-text review leaving a total of 12 studies for inclusion. Interventions were food-based, protein-based, carbohydrate-based, personalized, or used parenteral nutrition. Ten studies monitored anthropometric or body composition changes with three showing maintenance or improvements in lean mass, body mass index, triceps skinfold, and mid-upper arm circumference compared with the control group. Six studies monitored physical function but only the largest study found a beneficial effect on activities of daily living. Two of three studies showed the beneficial effects of nutritional intervention on cognition. CONCLUSION: There are few, high-quality, nutrition-based interventions in older adults ≥75 years. Despite heterogeneity, our findings suggest that large, longer-term (>2 weeks) nutritional interventions have the potential to maintain body composition, physical function, and cognition in adults aged 75 years and older during hospitalization.

RESUMEN

Social anxiety symptoms are one of the most common mental health concerns across the lifespan (Bandelow and Michaelis in Dialogues Clin Neurosci 17(3):327-335, 2015. https://doi.org/10.31887/DCNS.2015.17.3/bbandelow ) and are especially relevant during emerging adulthood, when social feedback occurs daily (Auxier and Anderson in Social media use in 2021, 2021. https://www.pewresearch.org/internet/2021/04/07/social-media-use-in-2021/ ) as emerging adults navigate new social environments. Two cognitive processes have been identified as relevant to social anxiety: high threat interpretation bias (i.e., the tendency to appraise threat from ambiguity; Rozenman et al. in Behav Ther 45(5):594-605, 2014. https://doi.org/10.1016/j.beth.2014.03.009 ; J Anxiety Disord 45:34-42, 2017. https://doi.org/10.1016/j.janxdis.2016.11.004 ) is associated with high social anxiety, whereas high perceived social support is associated with low social anxiety. In this study, emerging adults (N = 303) completed an online adaptation of the Chatroom task (Guyer et al. in Arch Gener Psychiatry 65(11):1303-1312, 2008. https://doi.org/10.1001/archpsyc.65.11.1303 ), an experimental paradigm designed to simulate social acceptance and rejection, as well as a performance-based measure of interpretation bias (Word Sentence Association Paradigm; Beard and Amir in Behav Res Ther 46(10):1135-1141, 2008. https://doi.org/10.1016/j.brat.2008.05.012 ), and a self-report measure of perceived social support (Multidimensional Scale of Perceived Social Support; Zimet et al. in J Pers Assess 52(1), 30-41, 1988. https://doi.org/10.1207/s15327752jpa5201_2 ). Social anxiety symptoms did not increase as a function of acceptance or rejection during the Chatroom task. However, there were significant interactions between each cognitive predictor and social anxiety change: emerging adults with low interpretation bias towards threat and emerging adults with high perceived social support both experienced decreases in social anxiety from pre- to post-Chatroom task, regardless of whether they were accepted or rejected during the Chatroom task. If replicated, low interpretation bias and high perceived social support may serve as promotive factors in social interactions for emerging adults.

RESUMEN

OBJECTIVE: Anxiety disorders are prevalent among youths and are often highly impairing. Cognitive-behavioral therapy (CBT) is an effective first-line treatment. The authors investigated the brain mechanisms associated with symptom change following CBT. METHODS: Unmedicated youths diagnosed with an anxiety disorder underwent 12 weeks of CBT as part of two randomized clinical trials testing the efficacy of adjunctive computerized cognitive training. Across both trials, participants completed a threat-processing task during functional MRI before and after treatment. Age-matched healthy comparison youths completed two scans over the same time span. The mean age of the samples was 13.20 years (SD=2.68); 41% were male (youths with anxiety disorders, N=69; healthy comparison youths, N=62). An additional sample including youths at temperamental risk for anxiety (N=87; mean age, 10.51 years [SD=0.43]; 41% male) was utilized to test the stability of anxiety-related neural differences in the absence of treatment. Whole-brain regional activation changes (thresholded at p<0.001) were examined using task-based blood-oxygen-level-dependent response. RESULTS: Before treatment, patients with an anxiety disorder exhibited altered activation in fronto-parietal attention networks and limbic regions relative to healthy comparison children across all task conditions. Fronto-parietal hyperactivation normalized over the course of treatment, whereas limbic responses remained elevated after treatment. In the at-risk sample, overlapping clusters emerged between regions showing stable associations with anxiety over time and regions showing treatment-related changes. CONCLUSIONS: Activation in fronto-parietal networks may normalize after CBT in unmedicated pediatric anxiety patients. Limbic regions may be less amenable to acute CBT effects.
