Growing evidence supports the unique pathways by which threat and deprivation, two core dimensions of adversity, confer risk for youth psychopathology. However, the extent to which these dimensions differ in their direct associations with youth psychopathology remains unclear. The primary aim of this preregistered meta-analysis was to synthesize the associations between threat, deprivation, internalizing, externalizing, and trauma-specific psychopathology. Because threat is proposed to be directly linked with socioemotional development, we hypothesized that the magnitude of associations between threat and psychopathology would be larger than those with deprivation. We conducted a search for peer-reviewed articles in English using PubMed and PsycINFO databases through August 2022. Studies that assessed both threat and deprivation and used previously validated measures of youth psychopathology were included. One hundred and twenty-seven articles were included in the synthesis (N = 163,767). Results of our three-level meta-analyses indicated that adversity dimension significantly moderated the associations between adversity and psychopathology, such that the magnitude of effects for threat (r’s = .21–26) were consistently larger than those for deprivation (r’s = .16–.19). These differences were more pronounced when accounting for the threat-deprivation correlation. Additional significant moderators included emotional abuse and youth self-report of adversity. Findings are consistent with the Dimensional Model of Adversity and Psychopathology, with clinical, research, and policy implications.

Drawing on a landscape analysis of existing data-sharing initiatives, in-depth interviews with expert stakeholders, and public deliberations with community advisory panels across the U.S., we describe features of the evolving medical information commons (MIC). We identify participant-centricity and trustworthiness as the most important features of an MIC and discuss the implications for those seeking to create a sustainable, useful, and widely available collection of linked resources for research and other purposes.

OBJECTIVES/SPECIFIC AIMS: To determine the association of participant’s characteristics and socio-cultural factors including acculturation, community identity and discrimination with the adherence to cancer screening guidelines and participants’ quality of life. METHODS/STUDY POPULATION: As part of the Cancer Disparities Research Network pilot cohort, the study recruited 333 participants across four sites: Boston Chinatown, African American communities in Philadelphia, and Hispanic communities in Columbus, and rural white communities in Appalachia, Ohio. Enrolled participants were eligible if they were 40 to 74 years old, did not live in a nursing home or other facility, and had no prior invasive cancer diagnosis. Additionally, each participant met at least one of the following criteria: living in a medically underserved area, having low literacy, low income (defined as 100% of the 2015 Federal Poverty Level FPL according to 2015 FPL Guidelines), or being uninsured or receiving subsidized health insurance coverage. Participants completed a baseline survey of demographic data, health status, including health behaviors and risk factors to cancer, Primary Care Physician (PCP) status and most recent breast, cervical, prostate, skin and colorectal cancer screenings. Information related to discrimination, acculturation or adaptation, and sense of belonging to their community was collected using validated instruments. RESULTS/ANTICIPATED RESULTS: Of the 333 participants enrolled in the study, 65.5% were women, 14.1% were 40-50 years of age, 59.8% were 51-64 years, and 26.1% were 65-74. The cohort was racially and ethnically diverse: 8.4% of participants identified as Hispanic, 30.3% as non-Hispanic White, 31.2% as non-Hispanic Black, 29.4% as non-Hispanic Asian, and 0.6% as Other. 62.2% spoke English, 8.1% Spanish, and 29.7% Chinese as their primary language. Low incomes were common: 33.6% reported incomes $15,000 or less, and 25.8% reported incomes between $15,000 and $24,999. Overall adherence to USPSTF guidelines on cancer screening rates was 77.9% for breast cancer, 71.1% for cervical cancer, and 67.7% for colorectal cancer. Analyses will present the association of acculturation, community identity, and discrimination with cancer screening and quality of life measures. DISCUSSION/SIGNIFICANCE OF IMPACT: This study will promote the increase of cancer disparities research, and reinforce the importance of inclusion and increased recruitment of diverse populations in future studies. By determining the potential factors associated with cancer disparities among minority populations, it may provide new information for clinicians to have more cultural sensitivity addressing potential disparities in the clinical setting. It will also promote the creation of more tailored interventions and programs to deliver adequate healthcare among these populations.

The powder-bed laser additive manufacturing (AM) process is widely used in the fabrication of three-dimensional metallic parts with intricate structures, where kinetically controlled diffusion and microstructure ripening can be hindered by fast melting and rapid solidification. Therefore, the microstructure and physical properties of parts made by this process will be significantly different from their counterparts produced by conventional methods. This work investigates the microstructure evolution for an AM fabricated AlSi10Mg part from its nonequilibrium state toward equilibrium state. Special attention is placed on silicon dissolution, precipitate formation, collapsing of a divorced eutectic cellular structure, and microstructure ripening in the thermal annealing process. These events alter the size, morphology, length scale, and distribution of the beta silicon phase in the primary aluminum, and changes associated with elastic properties and microhardness are reported. The relationship between residual stress and silicon dissolution due to changes in lattice spacing is also investigated and discussed.

Twenty-three chronic nonfluent aphasia patients with moderate or severe word-finding impairments and 11 with profound word-finding impairments received two novel picture-naming treatments. The intention treatment initiated picture-naming trials with a complex left-hand movement and was designed to enhance right frontal participation during word retrieval. The attention treatment required patients to view visual stimuli for picture-naming trials in their left hemispace and was designed to enhance right posterior perisylvian participation during word retrieval. Because the intention treatment addressed action mechanisms and nonfluent aphasia reflects difficulty initiating or maintaining action (i.e., language output), it was hypothesized that intention component of the treatment would enhance re-acquisition of picture naming more than the attention component. Patients with moderate and severe word-finding impairment showed gains with both treatments but greater incremental improvement from one treatment phase to the next with the intention than the attention treatment. Thus, the hypothesis that intention component would be a more active constituent than the attention component was confirmed for these patients. Patients with profound word-finding impairment showed some improvement with both treatments but no differential effects for the intention treatment. Almost all patients who showed treatment gains on either treatment also demonstrated generalization from trained to untrained items. (JINS, 2007, 13, 582–594.)

Links between verbs and gesture knowledge suggest that verb retrieval may be particularly amenable to gesture+verbal training (GVT) in aphasia compared to noun retrieval. This study examines effects of GVT for noun and verb retrieval in nine individuals with aphasia subsequent to left hemisphere stroke. Participants presented an array of noun and verb retrieval deficits, including impairments of semantic and/or phonologic processing. In a single-participant experimental design, we investigated effects of GVT for noun and verb retrieval in two counterbalanced treatment phases. Effects were evaluated in spoken naming and gesture production to pictured objects and actions. Spoken naming improvements associated with large effect sizes were noted for trained nouns (5/9) and verbs (5/9); no improvements were evident for untrained words. Gesture production improved for trained nouns (8/9) and verbs (6/9), and for untrained nouns (2/9) and verbs (2/9). No significant differences were evident between nouns and verbs in spoken naming or gesture production. Improvements were evident across individuals with varied sources of word retrieval impairments. GVT has the potential to improve communication by increasing spoken word retrieval of trained nouns and verbs and by promoting use of gesture as a means to communicate when word retrieval fails.

This investigation reports the results of a pilot study concerning the application of principles of use-dependent learning developed in the motor rehabilitation literature as Constraint Induced Therapy to language rehabilitation in a group of individuals with chronic aphasia. We compared treatment that required forced use of the language modality, Constraint Induced Language Therapy, (CILT) to treatment allowing all modes of communication. Both treatments were administrated intensively in a massed practice paradigm, using the same therapeutic stimuli and tasks. Results suggest that whereas both interventions yielded positive outcomes, CILT participants showed more consistent improvement on standard aphasia measures and clinician judgments of narrative discourse. These findings suggest that CILT intervention may be a viable approach to aphasia rehabilitation. (JINS, 2006, 12, 843–852.)

This study investigated two mechanism-based treatments for expressive aprosodia, a disturbance in emotional prosody thought to be governed by the right hemisphere. The 3 participants all suffered right CVA's resulting in expressive aprosodia. Presence of expressive aprosodia was determined by performance on two batteries of emotional communication. A single subject ABAC design was employed in which two treatments, one imitative and one cognitive linguistic, were assigned in random order. All participants in this study were randomly assigned to begin with the cognitive linguistic treatment. Probes of treated and untreated emotions were completed during baseline and therapy phases. Probe items were judged by a reliable, trained rater blind to time of testing. Visual and statistical analyses were completed. These analyses confirmed that both treatments were active. For example, effect size calculations confirmed modest to substantial treatment effects for both treatments in all 3 patients. Replication to increase confidence about treatment effect and enhance understanding of the neuromechanisms underlying aprosodia is underway. (JINS, 2004, 10, 786–793.)
