Background: Symptoms related to impaired visuospatial function are relatively common in patients with Parkinson's disease (PD). Restricted visual processing can directly hamper patients' motor function. For example, systematic biases in visual perception may influence navigational veering, thus directly affecting locomotion. In patients with PD, an impaired visual function is linked to negative feelings including depression, fearfulness and reduced self-efficacy. Art Therapy (AT) has the potential of recruiting different neural networks, including those concerned with high visual conscious perception. As such, AT may serve as a neurobehavioral intervention to improve multiple functional domains, including visuospatial functions and emotional wellness.
Method(s): This is a dual-phase exploratory study. 1: cross-sectional, controlled, biomarker study on 30 non-demented PD patients (H&Y 2-3) and 30 age-matched controls; 2: prospective, open label study involving 20 sessions of AT (2sessions/week). Motor and gait functions were assessed by MDS-UPDRS, Timed Up and Go test (TUG), and wearable accelerometers. Cognitive and Visuospatial functions were assessed by neuropsychological inventories (MoCA, Rey-Osterrieth FigureTest, Benton Visual Test), computerized testing (Navon VisualTest, Visual Research Test, and visual reaction time), and binocular eyetracking (Eyelink 2). Psychological wellness was assessed by Beck Depression Index (BDI), Modified Fatigue Impact Scale, and PROMIS-Self-Efficacy scales. Brain imaging included T1-weighted 3D high resolution, DWI, and RSfMRI sequences. Preliminary analyses were conducted on clinical data from 18 PD-patients and 14 controls completing the study. Eye tracking from 4 subjects was analyzed for exploratory purposes.
Result(s): PD-patients and controls were significantly different with respect to BDI score, Navon Visual Test, Rey Figure Test, UPDRSIII, and TUG-3 (maximum gait speed). Following AT, PD patients showed significant improvements in UPDRS-III, UPDRS-total, PROMIS (symptoms management), and Navon Visual Test (number of errors). A strong trend towards improved ReyeFigureTest was observed. On eye tracking analysis, significant increases in exploratory eye movements and fixation patterns were observed spatiotopically during examined stimulus regions.
Discussion(s): According to our preliminary findings, AT may improve visual-constructional abilities, visual recognition, and motor function. These improvements are accompanied by increased self-efficacy and changes in oculomotor behavior characterized by a more efficient visual exploration strategy. The duration of these potential benefits as well as their underlying mechanisms remain to be determined

BACKGROUND:Substance use and unprotected sex are prevalent among adolescents. The link between substance use and unprotected sex is well-established. Research has also highlighted how adolescents' attitudes and risk perceptions regarding unprotected sex, including concerns about pregnancy ("Getting pregnant would force me to grow up too fast"), are associated with unprotected sex and unplanned pregnancy. However, less research has examined the potential relationship between pregnancy concerns and substance use among adolescents. OBJECTIVES/OBJECTIVE:The study prospectively examined (1) differences in pregnancy concerns across patterns of substance use and (2) whether pregnancy concerns mediate the relationship between substance use and later unprotected sex among a sample of middle and high school students. METHOD/METHODS:98 adolescents [M(SD) age = 14.28(1.68), 59.4% female, 59.4% black/African American] completed self-report measures of marijuana and alcohol use, pregnancy concerns, and unprotected sex across three time points over 6 months (T1-T3). RESULTS:Substance users (alcohol/marijuana) reported fewer pregnancy concerns compared to non-substance users (t = 2.99, p = .04). Pregnancy concerns at T2 mediated the relationship between T1 lifetime substance use and later unprotected sex (T3) (indirect effect: b = 0.10, CI[.01-.41]; direct effect: b = 0.15, p = .32), controlling for gender, age, and race. More frequent substance use (T1) was related to fewer pregnancy concerns at T2 (b = -0.10, p = .04); fewer pregnancy concerns were related to increased likelihood of later unprotected sex (b = -1.02, p = .02). CONCLUSIONS:Findings offer new insight into associations between substance use and unprotected sex and suggest that substance use and sexual health interventions should target pregnancy concerns.

Detecting pathogen threats and avoiding disease is fundamental to human survival. The behavioral immune system (BIS) framework outlines a set of psychological functions that may have evolved for this purpose. Disgust is a core emotion that plays a pivotal role in the BIS, as it activates the behavioral avoidance motives that prevent people from being in contact with pathogens. To date, there has been little agreement on how disgust sensitivity might underlie moral judgments. Here, we investigated moral violations of "purity" (assumed to elicit disgust) and violations of "harm" (assumed to elicit anger). We hypothesized that individual differences in BIS-related traits would be associated with greater disgust (vs. anger) reactivity to, and greater condemnation of Purity (vs. Harm) violations. The study was pre-registered (https://osf.io/57nm8/). Participants (N = 632) rated scenarios concerning moral wrongness or inappropriateness and regarding disgust and anger. To measure individual differences in the activation of the BIS, we used our recently developed Body Odor Disgust Scale (BODS), a BIS-related trait measure that assesses individual differences in feeling disgusted by body odors. In line with our predictions, we found that scores on the BODS relate more strongly to affective reactions to Purity, as compared to Harm, violations. In addition, BODS relates more strongly to Moral condemnation than to perceived Inappropriateness of an action, and to the condemnation of Purity violations as compared to Harm violations. These results suggest that the BIS is involved in moral judgment, although to some extent this role seems to be specific for violations of "moral purity," a response that might be rooted in disease avoidance. Data and scripts to analyze the data are available on the Open Science Framework (OSF) repository: https://osf.io/tk4x5/. Planned analyses are available at https://osf.io/x6g3u/.

Academic medical centers (AMCs) today prioritize digital innovation. In efforts to develop and disseminate the best technology for their institutions, challenges arise in organizational structure, cross-disciplinary collaboration, and creative and agile problem solving that are essential for successful implementation. To address these challenges, the Digital DesignLab was created at NYU Langone Health to provide structured processes for assessing and supporting the capacity for innovative digital development in our research and clinical community. Digital DesignLab is an enterprise level, multidisciplinary, digital development team that guides faculty and student innovators through a digital development "pipeline", which consists of intake, discovery, bootcamp, development. It also provides a framework for digital health innovation and dissemination at the institution. This paper describes the Digital DesignLab's creation and processes, and highlights key lessons learned to support digital health innovation at AMCs.
