RESUMO
INTRODUCTION: Subjective experience of e-cigarettes may be an important factor in helping people who use combustible cigarettes switch completely to e-cigarettes to reduce harms from smoking. This paper describes a novel two-stage analysis using pleasure and satisfaction responses from Ecological Momentary Assessments (EMA) of both cigarette and e-cigarette use to predict future cigarette and e-cigarette tobacco use. METHODS: This observational study included adult users of cigarettes and e-cigarettes who provided 7-days of EMA, capturing cigarette and e-cigarette use, followed by biweekly reports of cigarette and e-cigarette use over one year. Participants were 279 adults who provided both cigarette and e-cigarette responses during the EMA. We employed a two-stage analytic approach in which EMA data were used to predict subsequent levels of cigarette and e-cigarette use. In the first stage, EMA responses of cigarette and e-cigarette events were modeled via a mixed-effects location scale (MELS) model to yield summaries of participants' means and variability on event-related ratings of pleasure and satisfaction. These EMA summaries served as predictors in the second stage analysis of the biweekly post-EMA longitudinal cigarette and e-cigarette use data. RESULTS: EMA pleasure and satisfaction ratings were similar for both products and predicted both longitudinal cigarette and e-cigarette use, even after controlling for baseline cigarette and e-cigarette dependence. Relatively higher levels of satisfaction with e-cigarettes were associated with greater decreases in cigarette use over time. CONCLUSIONS: Pleasure and satisfaction are important predictors of subsequent cigarette and e-cigarette use. IMPLICATIONS: Experienced subjective pleasure and satisfaction from e-cigarettes relative to cigarettes may be an important factor in helping individuals who smoke to switch completely to e-cigarettes as a harm reduction approach. In order to help sustain complete product switching and reduce dual use or relapse to smoking, e-cigarettes may need to deliver more satisfaction to the user compared to that experienced from cigarettes.
RESUMO
Objectives: This study investigated the Wechsler Adult Intelligence Scale-Fourth Edition Letter-Number Sequencing (LNS) subtest as an embedded performance validity indicator among adults undergoing an attention-deficit/hyperactivity disorder (ADHD) evaluation, and its potential incremental value over Reliable Digit Span (RDS). Method: This cross-sectional study comprised 543 adults who underwent neuropsychological evaluation for ADHD. Patients were divided into valid (n = 480) and invalid (n = 63) groups based on multiple criterion performance validity tests. Results: LNS total raw scores, age-corrected scaled scores, and age- and education-corrected T-scores demonstrated excellent classification accuracy (area under the curve of .84, .83, and .82, respectively). The optimal cutoff for LNS raw score (≤16), age-corrected scaled score (≤7), and age- and education-corrected T-score (≤36) yielded .51 sensitivity and .94 specificity. Slightly lower sensitivity (.40) and higher specificity (.98) was associated with a more conservative T-score cutoff of ≤33. Multivariate models incorporating both LNS and RDS improved classification accuracy (area under the curve of .86), and LNS scores explained a significant but modest proportion of variance in validity status above and beyond RDS. Chaining LNS T-score of ≤33 with RDS cutoff of ≤7 increased sensitivity to .69 while maintaining ≥.90 specificity. Conclusions: Findings provide preliminary evidence for the criterion and construct validity of LNS as an embedded validity indicator in ADHD evaluations. Practitioners are encouraged to use LNS T-score cutoff of ≤33 or ≤36 to assess the validity of obtained test data. Employing either of these LNS cutoffs with RDS may enhance the detection of invalid performance.
RESUMO
OBJECTIVE: Adverse childhood experiences (ACEs) are commonly reported in individuals presenting for attention-deficit hyperactivity disorder (ADHD) evaluation. Performance validity tests (PVTs) and symptom validity tests (SVTs) are essential to ADHD evaluations in young adults, but extant research suggests that those who report ACEs may be inaccurately classified as invalid on these measures. The current study aimed to assess the degree to which ACE exposure differentiated PVT and SVT performance and ADHD symptom reporting in a multi-racial sample of adults presenting for ADHD evaluation. METHOD: This study included 170 adults referred for outpatient neuropsychological ADHD evaluation who completed the ACE Checklist and a neurocognitive battery that included multiple PVTs and SVTs. Analysis of variance was used to examine differences in PVT and SVT performance among those with high (≥4) and low (≤3) reported ACEs. RESULTS: Main effects of the ACE group were observed, such that high ACE group reporting demonstrated higher scores on SVTs assessing ADHD symptom over-reporting and infrequent psychiatric and somatic symptoms on the Minnesota Multiphasic Personality Inventory-2-Restructured Form. Conversely, no significant differences emerged in total PVT failures across ACE groups. CONCLUSIONS: Those with high ACE exposure were more likely to have higher scores on SVTs assessing over-reporting and infrequent responses. In contrast, ACE exposure did not affect PVT performance. Thus, ACE exposure should be considered specifically when evaluating SVT performance in the context of ADHD evaluations, and more work is needed to understand factors that contribute to different patterns of symptom reporting as a function of ACE exposure.

OBJECTIVE: Internalizing psychopathology commonly co-occurs with attention-deficit/hyperactivity disorder (ADHD). Attention concerns are present in both ADHD and internalizing disorders, yet the neuropsychological functioning of those with comorbid ADHD and internalizing psychopathology is underexamined. METHOD: This study compared Conners' Continuous Performance Test-Third Edition (CPT-3) profiles across ADHD (n = 141), internalizing psychopathology (n = 78), and comorbid (ADHD/internalizing psychopathology; n = 240) groups. RESULTS: Compared to the internalizing psychopathology group, the comorbid group had higher mean T-scores on CPT-3 indices indicative of inattentiveness and impulsivity and more clinically elevated T-scores (T>60) on indices measuring inattentiveness and impaired sustained attention. Patients in the comorbid group were also more likely to have abnormal overall CPT-3 profiles (>2 elevated T-scores) than the ADHD and psychopathology only groups. CONCLUSION: Patients with comorbid ADHD/internalizing psychopathology may evidence a more impaired attentional performance on the CPT-3, which could aid in more tailored treatment planning.

INTRODUCTION: The Clinical Assessment of Attention Deficit-Adult is among the few questionnaires that offer validity indicators (i.e., Negative Impression [NI], Infrequency [IF], and Positive Impression [PI]) for classifying underreporting and overreporting of attention-deficit/hyperactivity disorder (ADHD) symptoms. This is the first study to cross-validate the NI, IF, and PI scales in a sample of adults with suspected or known ADHD. METHOD: Univariate and multivariate analyses were conducted to examine the independent and combined value of the NI, IF, and PI scores in predicting invalid symptom reporting and neurocognitive performance in a sample of 543 adults undergoing ADHD evaluation. RESULTS: The NI scale demonstrated better classification accuracy than the IF scale in discriminating patients with and without valid scores on measures of overreporting. Only NI scores significantly predicted validity status when used in combination with IF scores. Optimal cut-scores for the NI (≤51; 30% sensitivity / 90% specificity) and IF (≥4; 18% sensitivity / 90% specificity) scales were consistent with those reported in the original manual; however, these indicators poorly discriminated patients with invalid and valid neurocognitive performance. The PI scale demonstrated acceptable classification accuracy in discriminating patients with invalid and valid scores on measures of underreporting, albeit with an optimal cut-score (≥27; 36% sensitivity / 90% specificity) lower than that described in the manual. CONCLUSION: Findings provide preliminary evidence of construct validity for these scales as embedded validity indicators of symptom overreporting and underreporting. However, these scales should not be used to guide clinical judgment regarding the validity of neurocognitive test performance.
RESUMO
This study investigated the individual and combined utility of 10 embedded validity indicators (EVIs) within executive functioning, attention/working memory, and processing speed measures in 585 adults referred for an attention-deficit/hyperactivity disorder (ADHD) evaluation. Participants were categorized into invalid and valid performance groups as determined by scores from empirical performance validity indicators. Analyses revealed that all of the EVIs could meaningfully discriminate invalid from valid performers (AUCs = .69-.78), with high specificity (≥90%) but low sensitivity (19%-51%). However, none of them explained more than 20% of the variance in validity status. Combining any of these 10 EVIs into a multivariate model significantly improved classification accuracy, explaining up to 36% of the variance in validity status. Integrating six EVIs from the Stroop Color and Word Test, Trail Making Test, Verbal Fluency Test, and Wechsler Adult Intelligence Scale-Fourth Edition was as efficacious (AUC = .86) as using all 10 EVIs together. Failing any two of these six EVIs or any three of the 10 EVIs yielded clinically acceptable specificity (≥90%) with moderate sensitivity (60%). Findings support the use of multivariate models to improve the identification of performance invalidity in ADHD evaluations, but chaining multiple EVIs may only be helpful to an extent.
RESUMO
Objective: Focusing on body functionality - what the body can do - may benefit women's body image. This pilot study examined the effects of focusing on body functionality appreciation during an audio-guided mirror gazing task (F-MGT). Participants: 101 college women, M(SD)AGE = 19.49(1.31), were alternately assigned to F-MGT or a comparison with no guidance on how to examine the body, directed attention mirror gazing task (DA-MGT). Methods: Participants self-reported pre- and post-MGT body appreciation, state appearance satisfaction, and orientation to and satisfaction with physical functionality. Results: Group interactions were significant for body appreciation and functionality orientation. DA-MGT decreased body appreciation from pre- to post-MGT; F-MGT did not change. There were no significant interactions in post-MGT state appearance satisfaction or functionality satisfaction, though state appearance satisfaction increased significantly in F-MGT. Conclusions: Integrating body functionality may buffer against harmful effects of mirror gazing. Given F-MGT's brevity, additional work must assess its potential as an intervention technique.
RESUMO
INTRODUCTION: Disruptions in neural responses to reward are implicated in risk for Alcohol Use Disorder (AUD) and Major Depressive Disorder (MDD). It is not clear whether these findings extend to those in remission from AUD and MDD, a critical question as studies of remission can (a) rule out effects due to current symptoms, and (b) can reveal potential trait-like differences. METHODS: Individuals with and without remitted AUD (rAUD) and/or rMDD (rMDD) were drawn from a larger study to create four groups: rAUD (n = 54), rMDD (n = 66), rAUD + rMDD (n = 53), and a community control group (CCG; n = 81). Participants completed a validated monetary reward task during electroencephalogram (EEG). Multilevel models examined group differences in event-related potentials and time-frequency indices of reward and loss responsiveness, namely, reward positivity (RewP), feedback negativity (FN), reward-related delta power, and loss-related theta power. RESULTS: Analyses revealed that the rAUD + rMDD group had significantly higher reward-related delta activity than the three other groups (p-values < 0.01), which did not differ from each other. Sensitivity analyses revealed this relationship fell just above the threshold set for significance after controlling for residual current MDD and AUD symptoms (p =.05). There were no other group differences or significant interactions (p-values > 0.05). CONCLUSIONS: To our knowledge, this is the first study to show that individuals with remitted AUD and MDD demonstrate increased sensitivity to rewards compared to individuals with remitted AUD alone, MDD alone, and without AUD or MDD. These findings suggest heightened motivational salience to reward might be an important factor in comorbid AUD and MDD.

OBJECTIVE: Differences in the subjective effects of alcohol in different social contexts have been well documented, but little research examines affect during drinking in real-world social contexts. This study examined differences by social context in negative affect and positive affect during alcohol consumption. We hypothesized that negative affect and positive affect with drinking would vary as a function of social context (alone or with others). METHOD: A total of 257 young adults (M age = 21.3, 53.3% female) who were enrolled in a longitudinal, observational study assessing risk for smoking completed 7 days of ecological momentary assessment assessing alcohol use, affect, and social context at two time points of the study. Mixed-effects location scale analyses examined effects of being alone versus with others on positive affect and negative affect after drinking and compared with nondrinking times. RESULTS: Positive affect was higher when drinking with others versus alone, and negative affect was higher when drinking alone versus with others. Both negative affect and positive affect variability were higher when participants were drinking alone compared to with others, and negative affect variability was higher at low amounts of alcohol but decreased with increased drinking. CONCLUSIONS: These findings demonstrate that solitary drinking is less consistently reinforcing because of greater and more variable negative affect, as well as more variable positive affect. When drinking with others, increased and less variable positive affect suggests that social drinking may be particularly reinforcing in young adulthood.

Background: Adolescents and young adults may use cannabidiol (CBD) products in an attempt to reduce depression and anxiety symptoms, despite little research examining this use. This systematic review evaluated preclinical and clinical research on the effects of CBD on depressive and anxiety disorders in adolescence and young adulthood. To provide context, we discuss CBD's mechanism of action and neurodevelopmental effects. Methods: PubMed was searched for articles published through June 2022. Preclinical or clinical CBD administration studies with N > 1 that examined depressive and/or anxiety disorders were eligible. Results: Initially, 224 publications were identified. After excluding duplicates and applying eligibility criteria, 6 preclinical (depression: n≈133; anxiety: n≈161) and 4 clinical (anxiety: n=113) articles remained. Due to the low number of studies, results were synthesized qualitatively. The Oxford Centre for Evidence-Based Medicine 2011 Levels of Evidence were used to rate each study's evidence. The preclinical effects of CBD on depression-like behavior appear to differ by sex, early life stress, and duration of use. Despite no evidence that CBD exerts anxiolytic effects in preclinical adolescent models, CBD may reduce anxiety symptoms in human adolescents and young adults with anxiety disorders. Conclusions: The existing evidence suggests that CBD may reduce symptoms of anxiety in adolescents and young adults. However, the evidence is sparse and limited by variations in samples and CBD dosing duration. Further research is needed to understand the potential benefits and/or harms of CBD for depression and anxiety disorders in this population. Implications for clinical practice and research are discussed.
RESUMO
Objectives: Dual use of cigarettes and electronic nicotine delivery systems (ENDS) is increasingly common in adult smokers, who often report using ENDS to quit smoking. Elevated negative affect is an established predictor of increased difficulty quitting smoking combustible cigarettes but has not yet been examined in the context of cigarette cessation for dual users. Method: This study examined whether mood-related factors predict cigarette smoking cessation among dual users (N = 364) over 12-months. Self-reported cigarette smoking at 12 months, with abstinence defined as no smoking for the past 7 days, was the primary outcome variable. Logistic regression included baseline levels of depression symptoms (CES-D), anxiety symptoms (MASQ), and negative affect expectancies for smoking, with baseline nicotine dependence for cigarettes (NDSS), motivation to quit, age, race/ethnicity, rate of cigarette smoking at baseline, and ENDS usage at baseline and 12 months as covariates. Interactions between CES-D, MASQ, and negative affect expectancies were examined. We predicted that negative affect, especially for smokers who had high negative affect expectancies for smoking, would be negatively associated with quitting. Results: Contrary to expectations, negative affect constructs did not predict quitting. Baseline nicotine dependence for cigarettes, gender, and race/ethnicity significantly predicted the likelihood of cigarette cessation. Higher rates of ENDS use, higher motivation, and lower negative affect smoking expectancies were significantly correlated with quitting cigarettes. Conclusion: In this non-treatment seeking sample of dual users, negative affect did not predict cigarette cessation over and above nicotine dependence for cigarettes, gender, and race/ethnicity.

OBJECTIVE: Secondary consequences of juvenile idiopathic arthritis (JIA) may impact long-term health outcomes. This study examined differences in physical activity, cardiorespiratory fitness, adiposity, and functional performance in children and adolescents with JIA compared to their typically developing (TD) peers. METHODS: Participants with JIA (n = 32; 10-20 years old) and their TD peers (n = 35) volunteered for assessments of: daily moderate-to-vigorous physical activity (MVPA, body-worn accelerometer); peak oxygen consumption (VO2 Peak, incremental bike test); fat mass index (FMI, dual-energy X-ray absorptiometry); and triple-single-leg-hop (TSLH) distance. Statistical analyses were performed in R using four linear mixed-effect models with Bonferroni adjustment (⺠= 0.0125). Fixed effects were group, sex, and age. Participant clusters based on sex and age (within 1.5 years) were considered as random effects. RESULTS: Participants with JIA displayed lower mean daily MVPA than their TD peers [p = 0.006; ß (98.75% CI); -21.2 (-40.4 to -2.9) min]. VO2 Peak [p = 0.019; -1.4 (-2.5 to -0.2) ml/kg/min] decreased with age. Females tended to have lower VO2 Peak [p = 0.045; -6.4 (-13.0 to 0.4) ml/kg/min] and greater adiposity [p = 0.071; 1.4 (-0.1 to 3.0) kg/m2] than males. CONCLUSION: The findings support the need for strategies to promote MVPA participation in children and adolescents with JIA. Sex and age should be considered in research on the consequences of JIA.

OBJECTIVE: Juvenile idiopathic arthritis (JIA) affects body structure and function outcomes that may increase the risk of acute joint injury. The purpose of this study was to examine single leg squat (SLS) biomechanics for youth with JIA and their healthy peers. The study design was a matched pair cohort study. METHODS: Sixty-five youth (JIA n = 30; control n = 35) participated in this ethics-approved study. Participants performed 3 sets of 5 consecutive SLS tasks. Disease activity and functional status were assessed using the Juvenile Arthritis Disease Activity Score and Child Health Assessment Questionnaire. Indexed (most-affected leg [JIA]; dominant leg [control]) and contralateral extremity biomechanics were obtained using a 12-camera system. Outcomes included hip flexion/extension (FE), adduction/abduction (AA), and internal/external (IE) rotation range of motion (ROM). Data were analyzed using a multivariate random coefficient model in R (α⺠= 0.05). RESULTS: A total of 29 matched pairs were analyzed. Youth with JIA had low disease activity and performed the SLS with a more internally rotated hip (indexed leg P = 0.023, ß = -1.9°). Female participants displayed greater hip FE (indexed leg P = 0.015, ß = -4.3°; contralateral leg P = 0.005, ß = -4.8°) and IE ROM (indexed leg P = 0.021, ß = -2.1°) than male participants. Associations were observed for body mass index and hip IE ROM (contralateral leg P = 0.001, ß = -0.4°), knee flexion angle, and hip FE ROM (indexed leg P = 0.001, ß = 0.4°; contralateral leg P = 0.001, ß = 0.5°) and AA (indexed leg P = 0.010, ß = 0.1°; contralateral leg P = 0.002, ß = 0.2°). CONCLUSION: This study identified functional alterations for an SLS in youth with JIA. These findings support the use of physical therapy as part of a multidisciplinary management approach, to restore normal hip posture and movement.

OBJECTIVE: Juvenile idiopathic arthritis (JIA) is associated with altered body structure and function outcomes that may expose youth with JIA to a greater risk of secondary joint injury. This study aimed to examine differences in vertical drop jump (VDJ) biomechanics for youth with JIA and healthy youth (control group). METHODS: The present study was a matched pair cohort study. Youth with JIA (n = 30) and their age- and sex-matched control peers participated in this ethics-approved study. Lower-extremity biomechanics information was obtained using a motion analysis system (Motion Analysis) and 2 force plates (AMTI). Biomechanics outcomes included hip, knee, and ankle joint angles, ground reaction forces (GRF), and VDJ phase durations. Other outcomes included disease activity, physical disability, and sports participation. Matched pairs data (JIA-control) were analyzed using a multivariate random coefficient model (version 3.5.0, R Core Team; joint angles, potential confounders) and paired samples t-tests with Bonferroni correction (α = 0.0125; GRF, VDJ phase durations). RESULTS: Youth with JIA had low disease activity, pain, and disability scores. Youth with JIA maintained a more erect posture at the hip (ß = -4.0°, P = 0.004), knee (ß = 7.5°, P = 0.004) and ankle (ß = -2.6°, P = 0.001). GRF and phase durations outcomes did not meet criteria for significant differences. Knee extension increased with participant age (ß = -1.0°, P = 0.002), while female participants displayed greater hip flexion (ß = -6.6°, P = 0.001) and less ankle dorsiflexion (ß = 2.3°, P = 0.006). CONCLUSION: This study provides evidence for a stiff knee landing strategy by youth with JIA. These findings inform targets for physical therapy management to mitigate the risks of a secondary joint injury in sports participation.

OBJECTIVE: There is a growing call to identify specific outcome predictors in real-world eating disorder (ED) treatment settings. Studies have implicated several ED treatment outcome predictors [rapid response (RR), weight suppression, illness duration, ED diagnosis, and psychiatric comorbidity] in inpatient settings or randomized controlled trials of individual outpatient therapy. However, research has not yet examined outcome predictors in intensive outpatient programs (IOP). The current study aimed to replicate findings from randomized controlled research trials and inpatient samples, identifying treatment outcome predictors in a transdiagnostic ED IOP sample. METHOD: The current sample comprised 210 consecutive unique IOP patient admissions who received evidence-based ED treatment, M(SD)Duration = 15.82 (13.38) weeks. Weekly patient measures of ED symptoms and global functioning were obtained from patients' medical charts. RESULTS: In relative weight analysis, RR was the only significant predictor of ED symptoms post treatment, uniquely accounting for 45.6% of the predicted variance in ED symptoms. In contrast, baseline ED pathology was the strongest unique predictor of end-of-treatment global functioning, accounting for 15.89% of predicted variance. Baseline factors did not differentiate patients who made RR from those who did not. CONCLUSIONS: Consistent with findings in more controlled treatment settings, RR remains a robust predictor of outcome for patients receiving IOP-level treatment for EDs. Future work should evaluate factors that mediate and moderate RR, incorporating these findings into ED treatment design and implementation. LEVEL OF EVIDENCE: Level IV, uncontrolled intervention.

OBJECTIVE: Treating patients with eating disorders (EDs) is associated with an array of ethical concerns, including balancing patients' health and autonomy, access to care, and use of harm-reduction versus recovery-oriented treatment models. The primary aim of the current study is to gain a better understanding of ethical issues faced by ED practitioners by using a concept mapping, or Q-sort, approach. METHOD: A total of 12 practitioners completed the brainstorming phase and generated statements regarding ethical issues they faced while treating patients with EDs. A subsequent 38 practitioners completed a sorting task, where they created and labeled piles, into which they grouped each statement. Of those 38 participants, 30 rated both the frequency with which they encountered each ethical issue and its impact on patient care. RESULTS: A total of six clusters emerged: Insufficient Level of Care, Lack of Evidence-Based Practice, Insurance Barriers, Family Involvement, Patient Autonomy, and Limited Access to Expertise. Lack of Evidence-Based Practice, Insurance Barriers, and Insufficient Level of Care was the most frequent problem faced by ED practitioners, whereas Insurance Barriers and Patient Autonomy had the greatest impact. DISCUSSION: Findings outline frequent and impactful areas of ethical concern that arise when treating patients diagnosed with EDs. Practitioners most commonly reported that patient- and insurance-driven factors limited patient access to appropriate care. Regulations supporting the provision of evidence-based care should be emphasized in public health policy and advocacy efforts, given their impact in limiting the delivery of adequate patient care.

Severe, chronic irritability is one of the most frequently reported problems in youth referred for psychiatric care. Irritability predicts adult depressive and anxiety disorders, and long-term impairment. Reflecting this pressing public health need, severe, chronic, and impairing irritability is now codified by the DSM-5 diagnosis of disruptive mood dysregulation disorder (DMDD). Since DMDD has only recently been added as its own nosological class, efficacious treatments that specifically target severe irritability as it presents in DMDD are still being developed. In a recent pilot study, we described the general concept of exposure-based cognitive-behavioral therapy (CBT) for irritability. This mechanism-driven treatment is based on our pathophysiological model of irritability that postulates two underlying mechanisms, which potentiate each other: (1) heightened reactivity to frustrative nonreward, and (2) aberrant approach responses to threat. In this case report, we describe and illustrate the specific therapeutic techniques used to address severe irritability in an 11-year-old boy with a primary diagnosis of DMDD. Specific techniques within this CBT include motivational interviewing to build commitment and target oppositionality; creation of an anger hierarchy; in-session controlled, gradual exposure; and parent training focusing on contingency management to counteract the instrumental learning deficits in irritable youth. Parents learn to tolerate their own emotional responses to their youth's irritability (e.g., parents engage in their own exposure) and increase their adaptive contingencies for their youth's behavior (e.g., withdraw attention during unwanted behavior, praise desirable behavior). Future directions in the context of this CBT, such as leveraging technology, computational modeling, and pathophysiological targets, are discussed.

OBJECTIVE: Juvenile idiopathic arthritis (JIA) affects body structure and function and physical activity outcomes. The present study was undertaken to examine differences in gait kinematics during fixed-speed treadmill walking for youth with JIA and typically developing (TD) youth. METHODS: Sagittal plane gait kinematics were obtained using a 12-camera system (Motion Analysis) for youth with JIA (n = 30) and their age and sex-matched TD peers (n = 30). Outcomes included disease activity, pain, well-being, and peak sagittal hip, knee, and ankle joint angles. Kinematics were analyzed for the indexed leg (IL) (i.e., the affected leg of participants with JIA) compared to the dominant leg of TD participants and for the contralateral leg (CL) (i.e., the less/not affected leg of participants with JIA) compared to the nondominant leg of TD participants. Kinematics differences were investigated using multivariate Hotelling's T2 statistic (paired samples; α = 0.05) and simultaneous 95% confidence intervals (95% CIs). Potential confounders (age, sex, body mass index) were assessed using linear mixed-effects models with random effect for pairs. RESULTS: Youth with JIA had low disease activity, pain, and disability scores. Deviations in bilateral joint angles were observed (IL P = 0.015, CL P = 0.009). Youth with JIA walked with greater initial hip flexion (mean difference IL 2.8° [95% CI -0.6, 6.2]; CL 3.0° [-0.9, 6.9]) and lower knee extension (mean difference IL -2.2° [95% CI -4.4, 0.1]; CL -3.3° [-7.4, 0.8]), and lower hip extension during terminal stance (mean difference IL 3.4° [95% CI -0.3, 7.0]; CL 4.0° [1.0, 7.0]). CONCLUSION: Despite low disease activity, youth with JIA avoided the close-packed knee position, commonly associated with joint inflammation and pain. These findings highlight secondary consequences of JIA and inform targets for physical therapy management for youth with JIA.

Extreme hydrometeorological events such as hurricanes and cyclones are increasing in frequency and intensity due to climate change and often associated with flash floods in coastal, urbanized and industrial areas. Preparedness and response measures need to concentrate on toxicological and infectious hazards, the potential impact on environmental health, and threat to human lives. The recognition of the danger of flood water after hurricanes is critical. Effective health management needs to consider the likelihood and specific risks of toxic agents present in waters contaminated by chemical spills, bio-toxins, waste, sewage, and water-borne pathogens. Despite significant progress in the ability to rapidly detect and test water for a wide range of chemicals and pathogens, there has been a lack of implementation to adapt toxicity measurements in the context of flash and hurricane-induced flooding. The aim of this review was to highlight the need to collect and analyze data on toxicity of flood waters to understand the risks and prepare vulnerable communities and first responders. It is proposed that new and routinely used technologies be employed during disaster response to rapidly assess toxicity and infectious disease threats, and subsequently take necessary remedial actions.

Irritability and anxiety are two common clinical phenotypes that involve high-arousal negative affect states (anger and fear), and that frequently co-occur. Elucidating how these two forms of emotion dysregulation relate to perturbed neurodevelopment may benefit from alternate phenotyping strategies. One such strategy applies a bifactor latent variable approach that can parse shared versus unique mechanisms of these two phenotypes. Here, we aim to replicate and extend this approach and examine associations with neural structure in a large transdiagnostic sample of youth (N = 331; M = 13.57, SD = 2.69 years old; 45.92% male). FreeSurfer was used to extract cortical thickness, cortical surface area, and subcortical volume. The current findings replicated the bifactor model and demonstrate measurement invariance as a function of youth age and sex. There were no associations of youth's factor scores with cortical thickness, surface area, or subcortical volume. However, we found strong convergent and divergent validity between parent-reported irritability and anxiety factors with clinician-rated symptoms and impairment. A general negative affectivity factor was robustly associated with overall functional impairment across symptom domains. Together, these results support the utility of the bifactor model as an alternative phenotyping strategy for irritability and anxiety, which may aid in the development of targeted treatments.
