RESUMO

BACKGROUND: Engaging in active transport will enable individuals across the life course to increase their habitual levels of physical activity. The aim of this study was to engage citizen scientists (CS) to identify factors that influence active transport in their community. METHODS: The Our Voice citizen science methodology developed at Stanford University was employed. CS completed a "discovery walk," taking photos of things that help or hinder active transport. Three groups were recruited: children aged 10-12 years (n = 11), adults (n = 12), and older adults >65 years (n = 10). CS rated each photo and provided a narrative explaining their reason for taking the photo. Once all CS in a specific age group had completed the walk, they met for a group discussion. The CS worked together to analyze the data, arranging them into themes and identifying priority actions. Two CS representatives from each age group presented their findings to the local council decision makers. RESULTS: Children highlighted the need for safer crossings, especially from their school to the local park, and suggested zebra crossings as a solution. The adults highlighted that road signs prioritized vehicles, not pedestrians, and requested that this be reversed. Older adults noted that the poor condition of the pavements made it harder for people in wheelchairs to navigate. The CS recommendations have informed the council's walking and cycling network program. CONCLUSION: Engaging with citizen science provided the community with an opportunity to advocate for meaningful yet realistic improvements in the built environment that could promote neighborhood active transport and physical activity across the lifespan.

RESUMO

Children of incarcerated parents may grieve this loss, yet perceptions of their grief are understudied. Using vignettes varying by age (adult/child) and grief response (prolonged/resilient), we examined differences between perceptions of adults and children grieving parental incarceration. Participants rated grief response appropriateness, comfort providing support, and grief therapy recommendations for the grieving person in the vignette. Participants perceived resilience as more appropriate than prolonged grief [F (1, 224) = 9.02, p = .003, η2 = .04]. Age did not predict outcomes. Recommending grief therapy was higher for prolonged grief, yet 53% of participants with resilient vignettes recommended the person should seek grief therapy, which is concerning given possible iatrogenic effects. Thus, laypeople may have stigma toward individuals grieving parental incarceration, regardless of age.

RESUMO

As computer vision algorithms increase in capability, their applications in clinical systems will become more pervasive. These applications include: diagnostics, such as colonoscopy and bronchoscopy; guiding biopsies, minimally invasive interventions, and surgery; automating instrument motion; and providing image guidance using pre-operative scans. Many of these applications depend on the specific visual nature of medical scenes and require designing algorithms to perform in this environment. In this review, we provide an update to the field of camera-based tracking and scene mapping in surgery and diagnostics in medical computer vision. We begin with describing our review process, which results in a final list of 515 papers that we cover. We then give a high-level summary of the state of the art and provide relevant background for those who need tracking and mapping for their clinical applications. After which, we review datasets provided in the field and the clinical needs that motivate their design. Then, we delve into the algorithmic side, and summarize recent developments. This summary should be especially useful for algorithm designers and to those looking to understand the capability of off-the-shelf methods. We maintain focus on algorithms for deformable environments while also reviewing the essential building blocks in rigid tracking and mapping since there is a large amount of crossover in methods. With the field summarized, we discuss the current state of the tracking and mapping methods along with needs for future algorithms, needs for quantification, and the viability of clinical applications. We then provide some research directions and questions. We conclude that new methods need to be designed or combined to support clinical applications in deformable environments, and more focus needs to be put into collecting datasets for training and evaluation.

RESUMO

Quantifying performance of methods for tracking and mapping tissue in endoscopic environments is essential for enabling image guidance and automation of medical interventions and surgery. Datasets developed so far either use rigid environments, visible markers, or require annotators to label salient points in videos after collection. These are respectively: not general, visible to algorithms, or costly and error-prone. We introduce a novel labeling methodology along with a dataset that uses said methodology, Surgical Tattoos in Infrared (STIR). STIR has labels that are persistent but invisible to visible spectrum algorithms. This is done by labelling tissue points with IR-fluorescent dye, indocyanine green (ICG), and then collecting visible light video clips. STIR comprises hundreds of stereo video clips in both in vivo and ex vivo scenes with start and end points labelled in the IR spectrum. With over 3,000 labelled points, STIR will help to quantify and enable better analysis of tracking and mapping methods. After introducing STIR, we analyze multiple different frame-based tracking methods on STIR using both 3D and 2D endpoint error and accuracy metrics. STIR is available at https://dx.doi.org/10.21227/w8g4-g548.

RESUMO

BACKGROUND: Preschool children with externalizing problems are at risk for short- and long-term difficulties and preschool externalizing problems (PEP) are influenced by several caregiver factors. One such factor is caregiver adverse childhood experiences (ACEs). Researchers have investigated how caregiver ACEs are related to PEP by identifying risk factors to account for this association. However, research on caregiver factors associated with fewer PEP is limited. Particularly, factors that contribute to caregiver resilience may be adaptive caregiver characteristics that negatively relate to PEP, even when adjusting for caregiver ACEs. OBJECTIVE: The present study sought to address a gap in the literature by examining the impact of different types of factors that contribute to caregiver resilience (e.g., caregiver social-ecological factors or caregiver positive childhood experiences) as promotive factors of lower PEP. PARTICIPANTS AND SETTING: Participants included 125 caregiver-child dyads recruited from the community. METHOD: Participating caregivers completed measures of their own and their child's demographic information, caregiver ACEs, caregiver social-ecological factors, caregiver positive childhood experiences, and PEP. RESULTS: Overall, positive caregiver childhood experiences (r = -0.25, p < .01), and not caregiver social-ecological factors (r = -0.13, p = .15), demonstrated a significant negative association with PEP. However, this relation became statistically non-significant when adjusting for caregiver ACEs (ß = -0.12, p = .20). CONCLUSIONS: Given the association between caregiver ACEs and PEP, this study highlights the importance of assessing a caregiver's ACEs, specifically when working with caregivers seeking parent training for disruptive child behaviors. There should be a continued focus on ecological and family strengths and differential impacts as they relate to PEP.

RESUMO

Importance: Traumatic brain injury (TBI) is known to cause widespread neural disruption in the cerebrum. However, less is known about the association of TBI with cerebellar structure and how such changes may alter executive functioning. Objective: To investigate alterations in subregional cerebellum volume and cerebral white matter microstructure after pediatric TBI and examine subsequent changes in executive function. Design, Setting, and Participants: This retrospective cohort study combined 12 data sets (collected between 2006 and 2020) from 9 sites in the Enhancing Neuroimaging Genetics Through Meta-Analysis Consortium Pediatric TBI working group in a mega-analysis of cerebellar structure. Participants with TBI or healthy controls (some with orthopedic injury) were recruited from trauma centers, clinics, and institutional trauma registries, some of which were followed longitudinally over a period of 0.7 to 1.9 years. Healthy controls were recruited from the surrounding community. Data analysis occurred from October to December 2022. Exposure: Accidental mild complicated-severe TBI (msTBI) for those in the TBI group. Some controls received a diagnosis of orthopedic injury. Main Outcomes and Measures: Volume of 18 cerebellar lobules and vermal regions were estimated from 3-dimensional T1-weighted magnetic resonance imaging (MRI) scans. White matter organization in 28 regions of interest was assessed with diffusion tensor MRI. Executive function was measured by parent-reported scores from the Behavior Rating Inventory of Executive Functioning. Results: A total of 598 children and adolescents (mean [SD] age, 14.05 [3.06] years; range, 5.45-19.70 years; 386 male participants [64.5%]; 212 female participants [35.5%]) were included in the study, with 314 participants in the msTBI group, and 284 participants in the non-TBI group (133 healthy individuals and 151 orthopedically injured individuals). Significantly smaller total cerebellum volume (d = -0.37; 95% CI, -0.52 to -0.22; P < .001) and subregional cerebellum volumes (eg, corpus medullare; d = -0.43; 95% CI, -0.58 to -0.28; P < .001) were observed in the msTBI group. These alterations were primarily seen in participants in the chronic phase (ie, >6 months postinjury) of injury (total cerebellar volume, d = -0.55; 95% CI, -0.75 to -0.35; P < .001). Smaller cerebellum volumes were associated with higher scores on the Behavior Rating Inventory of Executive Functioning Global Executive Composite score (ß = -208.9 mm3; 95% CI, -319.0 to -98.0 mm3; P = .008) and Metacognition Index score (ß = -202.5 mm3; 95% CI, -319.0 to -85.0 mm3; P = .02). In a subset of 185 participants with longitudinal data, younger msTBI participants exhibited cerebellum volume reductions (ß = 0.0052 mm3; 95% CI, 0.0013 to 0.0090 mm3; P = .01), and older participants slower growth rates. Poorer white matter organization in the first months postinjury was associated with decreases in cerebellum volume over time (ß=0.52 mm3; 95% CI, 0.19 to 0.84 mm3; P = .005). Conclusions and Relevance: In this cohort study of pediatric msTBI, our results demonstrated robust cerebellar volume alterations associated with pediatric TBI, localized to the posterior lobe. Furthermore, longitudinal cerebellum changes were associated with baseline diffusion tensor MRI metrics, suggesting secondary cerebellar atrophy. These results provide further understanding of secondary injury mechanisms and may point to new opportunities for intervention.

RESUMO

Cannabis use and the prevalence of cannabis use disorder (CUD) among emerging adults are on the rise. Several indicators of cannabis use (e.g., quantity, frequency) as they relate to negative outcomes have been posited in the extant literature. Despite research examining links between indicators and cannabis outcomes, few assessments of cannabis use indicators exist. The Daily Sessions, Frequency, Age of Onset, and Quantity of Cannabis Use Inventory (DFAQ-CU) was developed to assess cannabis use across a range of factors. However, the factor structure of the DFAQ-CU has not been replicated. Further, the DFAQ-CU was modeled using reflective strategies despite formative strategies being conceptually appropriate. The present study utilized principal components analyses (PCA) and principal axis factoring (PAF) to evaluate the structure of the DFAQ-CU. PCA yielded a four-component solution; PAF resulted in a five-factor solution. Linear regression found significant relations between PCA components and PAF factors with CUD symptoms and cannabis-related problems; however, effect sizes were larger for the PAF suggesting possible misdisattenuation. The PCA components demonstrated evidence of discriminant and convergent validity with measures of cannabis and alcohol behavior. The study informs research and clinical work through the refinement of cannabis use assessment and enhancing our understanding of the importance of model selection.

RESUMO

PURPOSE OF REVIEW: Attention-deficit/hyperactivity disorder (ADHD) is a heterogeneous and complex neurodevelopmental disorder related to disruptions in various neuronal structures and pathways, dopamine (DA) transporter, and receptor genes, resulting in cognitive and regulation deficits. This article reviews recent research on the biological mechanisms and markers, clinical manifestations, treatments, and outcomes of adult ADHD as well as current controversies within the field. RECENT FINDINGS: New research identifies white matter disruptions in multiple cortical pathways in adults with ADHD. New treatments for ADHD in adults such as viloxazine ER have shown preliminary effectiveness in addition to research showing transcranial direct current stimulation can be an effective treatment for adults with ADHD. Although questions exist about the effectiveness of current assessments of and treatments for adult ADHD, recent findings represent a step towards improving the quality of life and outcomes for individuals experiencing this life-long, chronic health condition.

RESUMO

OBJECTIVE: While the lack of relation between performance- and inventory-based executive function (EF) measures is well documented, there remains ambiguity between self-report EFs and closely related constructs (e.g., impulsivity) assessed via the same method. The degree of convergence between purported EF measures with similar yet distinct constructs contain important theoretical implications for available EF assessment strategies and their construct validity. A newer measure of EF, the Behavior Regulation Inventory of Executive Functions-Adult (BRIEF-A), allows for more direct comparisons to self-reported measures of impulsivity, such as the commonly used Urgency, Planning, Perseverance, Sensation Seeking-Positive Urgency (UPPS-P) assessment. METHOD: The present study used factor analysis and hierarchical regression to explore the associations between the BRIEF-A and UPPS-P, using alcohol and cannabis consumption across various outcomes (i.e., quantity-frequency and consequences) as an external criterion. Participants were 339 undergraduate students (Mage = 19.35; Female = 63%) from a large southwestern university. RESULTS: The BRIEF-A and UPPS-P demonstrated strong correlations at both higher- and lower order facets. While the BRIEF-A was a significant correlate to many substance use outcomes, these relations were generally weaker than those seen with the UPPS-P. Hierarchical regression suggested limited contributions of the BRIEF-A over and above the UPPS-P. CONCLUSIONS: Overall, this study suggested substantial overlap between impulsigenic factors and EFs when measured by self-report, and limited utility of EF measures to account for unique variance with substance use outcomes in this sample.

RESUMO

OBJECTIVE: ADHD is a neurodevelopmental disorder affecting millions of adults worldwide. Continuous performance tests (CPTs) are widely used as assessment and diagnostic tools; however, their use in diagnosing undiagnosed ADHD in adults has been questioned due to their lack of specificity and sensitivity. This review sought to outline relevant findings concerning the diagnostic utility of the Conner's Continuous Performance Test (CCPT) in adults. METHOD: This systematic review followed the a priori guide outlined by the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statement. Articles were gathered from PsycINFO, PsycArticles, Cochrane, Scopus, Google Scholar, and PubMed. RESULTS: Thirty-five articles were reviewed and analyzed. Most articles reviewed used outpatient and university populations. Moderate reliability, subpar discriminant and ecological validity, and mixed sensitivity and specificity were noted. CONCLUSION: The results of this review lend support to previous critiques of the CCPT's diagnostic and utility as a treatment measure.

RESUMO

OBJECTIVE: Attaining competence in assessment is a necessary step in graduate training and has been defined to include multiple domains of training relevant to this attainment. While important to ensure trainees meet these standards of training, it is critical to understand how and if competence shapes a trainees' professional identity, therein promoting lifelong competency. METHODS: The current study assessed currently enrolled graduate trainees' knowledge and perception of their capabilities related to assessment to determine if self-reported and performance-based competence would incrementally predict their intention to use assessment in their future above basic training characteristics and intended career interests. RESULTS: Self-reported competence, but not performance-based competence, played an incremental role in trainees' intention to use assessments in their careers. Multiple graduate training characteristics and practice experiences were insignificant predictors after accounting for other relative predictors (i.e., intended career settings, integrated reports). CONCLUSION: Findings are discussed about the critical importance of incorporating a hybrid competency-capability assessment training framework to further emphasize the role of trainee self-efficacy in hopes of promoting lifelong competence in their continued use of assessments.

RESUMO

Growing up in a family environment characterized by neglectful parenting, overt conflict, and unsupportive relationships is associated with poor health in adulthood. A risky early family environment may also be associated with obesity in adulthood, likely through the activation of the HPA axis. Likewise, the GABAergic (gamma-aminobutyric acid) T>C single nucleotide polymorphism in the 1519 nucleotide position of the GABAAα6 receptor subunit gene has been associated with a predisposition to a higher body mass index and a larger waist circumference. Participants (n = 213, Mage = 30.13 years, SD = 10.85; 57.7% men) from the Pittsburgh Cold Study 3 completed a demographic questionnaire, the Risky Families Questionnaire (RFQ) and had their height, weight, and waist circumference measured during a physical exam. Participant DNA was recovered from buccal swabs and genotyped for the various allelic types of the SNP according to published protocols. In secondary data analyses, we tested the hypothesis that early family environment and GABRA6 would be positively associated with body mass index and waist circumference. We also examined diurnal cortisol as a mechanism linking both early risky family environment and GABRA6 to metabolic outcomes. The findings provide evidence that a risky early family environment may exert more influence than genetic predisposition when determining the indices of metabolic health in adulthood.

RESUMO

The current study integrates previous research on adverse childhood experiences (ACEs) and long-term health outcomes to examine associations between ACEs, sleep duration, and depression in a diverse, mostly healthy, sample of young adults. We examine whether sleep duration mediates the association between ACEs and depression among young adults, and whether ethnicity may moderate observed relationships between ACEs, sleep duration and depression. Data were collected from 518 young adults (66.8% female, Mage=19.79 years, SDage=3.43 years) enrolled in undergraduate Psychology courses at a large Southwestern university. Participants primarily reported their racial/ethnic background as Non-Hispanic White (60.6%) and Hispanic/Latino (25.1%). Participants self-reported their ACEs exposure, sleep characteristics, and depressive symptoms. In addition to calculating overall exposure to ACEs, scores for the specific dimensions of adversity were also calculated (Abuse, Neglect, Exposure to Violence). Results supported a mediation model whereby higher reports of ACEs were associated with depressive symptoms both directly and through sleep duration. Results were not moderated by ethnicity. Findings provide support for sleep duration as one potential pathway through which ACEs may be associated with depressive symptoms in young adulthood, and suggest that this pathway is similar in Hispanic and non-Hispanic young adults.

RESUMO

There is growing interest in saliva microRNAs (miRNAs) as non-invasive biomarkers for human disease. Such an approach requires understanding how differences in experimental design affect miRNA expression. Variations in technical methodologies, coupled with inter-individual variability may reduce study reproducibility and generalizability. Another barrier facing salivary miRNA biomarker research is a lack of recognized "control miRNAs". In one of the largest studies of human salivary miRNA to date (922 healthy individuals), we utilized 1225 saliva samples to quantify variability in miRNA expression resulting from aligner selection (Bowtie1 vs. Bowtie2), saliva collection method (expectorated vs. swabbed), RNA stabilizer (presence vs. absence), and individual biological factors (sex, age, body mass index, exercise, caloric intake). Differential expression analyses revealed that absence of RNA stabilizer introduced the greatest variability, followed by differences in methods of collection and aligner. Biological factors generally affected a smaller number of miRNAs. We also reported coefficients of variations for 643 miRNAs consistently present in saliva, highlighting several salivary miRNAs to serve as reference genes. Thus, the results of this analysis can be used by researchers to optimize parameters of salivary miRNA measurement, exclude miRNAs confounded by numerous biologic factors, and identify appropriate miRNA controls.

RESUMO

Disability is an important facet of diversity. Although diversity in clinical training in health service psychology has improved considerably, training often neglects accessibility and inclusion for individuals with sensory disabilities. The limited research to date documents that trainees with sensory disabilities (TSD) report extensive barriers and are consistently under-represented in clinical settings. Further, few resources have been developed to guide accommodating TSD in clinical training. Accordingly, our goals in this article are two-fold: (1) to highlight the barriers in clinical training faced by TSD and (2) to provide recommendations for trainees, supervisors, clinical leadership, and directors of clinical training to improve accessibility and inclusion for TSD. We offer vignettes to illustrate barriers faced by TSD and suggest guidelines to improve access for TSD.

RESUMO

Adverse childhood experiences (ACEs) are related to a host of deleterious physical and mental health outcomes. The ACE-International Questionnaire (ACE-IQ) was developed to assess categories of ACEs (e.g., sexual, emotional, and physical abuse) in internationally representative samples. Though the ACE-IQ has been used world-wide, little work has examined the structure of this measure. Further, much of the modeling techniques implemented lacked theoretical rationale. The present work used two principal components analyses (PCA) to evaluate the ACE-IQ structure using both the identified ACE categories as defined by the World Health Organization (WHO) and using the ACE-IQ items as individual indicators. Using the WHO method, a two-component structure was indicated. Alternatively, a PCA of the individual items yielded a six-component structure. Results highlight the importance of theoretically grounded measure evaluation and the potential distinctions amongst types of ACEs. Implications and future directions for research and practice are discussed.

RESUMO

The 2020 general election occurred while many parts of the nation were under emergency orders related to the COVID-19 pandemic. This led to new requirements and considerations for voting systems. We introduce a model of the voting process to capture pandemic-related changes. Using a discrete event simulation case study of Milwaukee, WI, we study how to design in-person voting systems whose performance are robust to pandemic conditions, such as protective measures implemented during the COVID-19 pandemic. We assess various voting system designs on the voter wait times, voter sojourn times, line lengths at polling locations, voter time spent inside, and the number of voters inside. The analysis indicates that poll worker shortages, social distancing, and personalized protective equipment usage and sanitation measures can lead to extremely long voter wait times. We consider several design choices for mitigating the impact of pandemic-related changes on voting metrics. The case study suggests that long wait times can be avoided by staffing additional check-in locations, expanding early voting, and avoiding consolidated polling locations. Additionally, the analysis suggests that implementing a priority queue discipline has the potential to reduce waiting times for vulnerable populations at increased susceptibility to health risks associated with in-person voting.

RESUMO

INTRODUCTION: Suicide is a leading cause of death worldwide. Although inconsistent, impulsivity has been identified as a risk factor for suicidal thoughts and behaviors, and these inconsistent findings can largely be attributed to varying operationalizations of impulsivity. As such, the UPPS model of impulsivity provides a clear definition of impulsivity and its associated features that may provide utility in clarifying unreliable findings between impulsivity and suicide. This review aimed to summarize relevant information pertaining to the UPPS model of impulsivity and suicide. METHODS: This systematic review followed the a priori guide outlined by the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statement. Articles were gathered from PsycINFO, PsycArticles, Scopus, and PubMed. RESULTS: Twenty-eight articles were reviewed and analyzed. Most articles reviewed reported on indirect (i.e., through mediators and moderators) associations between the UPPS dimensions and suicidal behaviors. Additionally, results noted limited between-group differences in UPPS facets among individuals with a history of suicide attempts and those without a history of suicide attempts, those with a history of suicide attempts and individuals with suicide ideation, and those with suicide ideation and those without suicide ideation, with the exception of lack of premeditation. DISCUSSION: The results of this review indicate support for the UPPS model of impulsivity as a theoretical starting point when examining the relation between impulsivity and suicide. Further, findings are helpful for clinicians and case conceptualization. Particularly, suicide risk assessment and treatment would be impacted based on impulsivity traits and suicide history.

RESUMO

OBJECTIVE: Environmental barriers limit exercise in adolescents, but the contribution of cognitive barriers are not as well characterized. Previous findings suggest future thinking may predict exercise intent, which has been linked to health and actual exercise. However, these models may be incomplete as they do not systematically incorporate potential cognitive contributions (e.g., executive function capacity) to exercise intent. This study investigated the possible mediating role of executive function capacity in the relation between future thinking and exercise intent. METHODS: Data for the mediation models was collected from 101 adolescents aged 11-17 (M = 13.09) in a summer enrichment program. Adolescent participants completed self-report measures including Consideration of Future Consequences Scale (CFCS), Intent to Exercise, and Behavior Rating Inventory of Executive Function, Second Edition (BRIEF-2). RESULTS: This study found that self-reported executive function capacity mediated the relation between future thinking and exercise intent even when controlling for age and subjective socioeconomic status. CONCLUSIONS: While some exercise interventions aim to increase future thinking, this study provides support for additional research into how interventions may benefit from targeting executive function capacity directly to increase exercise intent and actual exercise.

RESUMO

High-voltage LiNi0.5Mn1.5O4 (LNMO) spinel offers high specific energy and good rate capability with relatively low raw-material cost due to cobalt-free and manganese-rich chemical compositions. Also, increasing mass loading (mg/cm2) by thickening cathodes has been one of the focused areas to greatly improve the energy density of lithium-ion batteries (LIBs) at the cell level. The LNMO cathode made with a polyvinylidene fluoride (PVdF) binder, however, suffers from an oxidative decomposition of liquid electrolytes and cathode delamination from a current collector. This problem is exacerbated with an increase in thickness. In this study, we developed a lithium polyacrylate (LiPAA)-sodium alginate (Na-Alg) composite binder series that offer positive multifunctions such as enhancing cathode adhesion and cohesion, improving cycle life, creating an effective passivating layer at the cathode-electrolyte interface (CEI), and lowering cell impedance. Comprehensive design of systematic experiments revealed a close chemo-mechano-electrochemical relationship in the thick high-voltage cathodes. Among the various binder compositions, the LiPAA (30 wt %)-Na-Alg (70 wt %) binder offered a strong adhesion property and positive multifunctions at the CEI layer, which consequently stabilized the solid-electrolyte interfacial (SEI) layer on the graphite anode and improved LIB performances. This novel composite binder will be applicable to various types of thick cathodes in future studies.
