Patient and care team perspectives on an app to support Hospital at Home admission decision making.

Background: Hospital at Home (HaH) programs are used throughout the United States and are beneficial in both providing patients care in environments most comfortable to them and freeing up inpatient beds. Better informing patients about HaH programs, while promoting shared decision-making (SDM), should be prioritized by health systems. SDM apps may promote increased patient agency and understanding of complex HaH care decisions.

Buffering anti-fat attitudes using contact: The roles of contact quantity, duration, favorability, and intergroup anxiety.

Decades of intergroup contact research have found that contact with outgroups reduces negative attitudes. Yet, few studies have examined the association between contact and anti-fat attitudes. Furthermore, testing different facets of contact, namely contact quantity versus contact duration, provides more precise theoretical predictions for their effectiveness in this under-tested context.

Experimental Examination of Social Transmission of Health Information using an Online Platform.

The "viral" nature of information transmission has the potential to transmit both accurate and inaccurate information. The present experiment examines the social transmission of health information, focusing on disorder etiology. Participants were placed in one of three generations of social transmission chains.

Transmission of disorder and etiological information: Effects on health knowledge recollection and health-related cognition.

Biased transmission of health knowledge has far-reaching effects on information reproduction and health-related cognitions. We examined whether transmissions of different types of disorder and etiological information influence recollections of health knowledge and evaluations of patients, by simulating the digital transmission of information. Transmission chains of four non-interacting persons (i.

Genetic Knowledge within a National Australian Sample: Comparisons with Other Diverse Populations.

Background: Genetic knowledge, which plays important functions in our understanding of science, health, social groupings, and even behaviour, has been evaluated in past studies with various populations. This wide reach of genetics means that different types of items are used to assess genetic knowledge, which restricts meaningful comparisons across time- and locale-based studies.

Aim: The present study addresses this limitation by recruiting an Australia-wide sample and evaluating their genetic knowledge using items sourced from four diverse samples.

Endogenous antigen processing drives the primary CD4+ T cell response to influenza.

By convention, CD4+ T lymphocytes recognize foreign and self peptides derived from internalized antigens in combination with major histocompatibility complex class II molecules. Alternative pathways of epitope production have been identified, but their contributions to host defense have not been established. We show here in a mouse infection model that the CD4+ T cell response to influenza, critical for durable protection from the virus, is driven principally by unconventional processing of antigen synthesized within the infected antigen-presenting cell, not by classical processing of endocytosed virions or material from infected cells.

Epigenomic analysis of primary human T cells reveals enhancers associated with TH2 memory cell differentiation and asthma susceptibility.

A characteristic feature of asthma is the aberrant accumulation, differentiation or function of memory CD4(+) T cells that produce type 2 cytokines (TH2 cells). By mapping genome-wide histone modification profiles for subsets of T cells isolated from peripheral blood of healthy and asthmatic individuals, we identified enhancers with known and potential roles in the normal differentiation of human TH1 cells and TH2 cells. We discovered disease-specific enhancers in T cells that differ between healthy and asthmatic individuals.

Toward a Network Model of MHC Class II-Restricted Antigen Processing.

The standard model of Major Histocompatibility Complex class II (MHCII)-restricted antigen processing depicts a straightforward, linear pathway: internalized antigens are converted into peptides that load in a chaperone dependent manner onto nascent MHCII in the late endosome, the complexes subsequently trafficking to the cell surface for recognition by CD4(+) T cells (TCD4+). Several variations on this theme, both moderate and radical, have come to light but these alternatives have remained peripheral, the conventional pathway generally presumed to be the primary driver of TCD4+ responses. Here we continue to press for the conceptual repositioning of these alternatives toward the center while proposing that MHCII processing be thought of less in terms of discrete pathways and more in terms of a network whose major and minor conduits are variable depending upon many factors, including the epitope, the nature of the antigen, the source of the antigen, and the identity of the antigen-presenting cell.

An integrated nano-scale approach to profile miRNAs in limited clinical samples.

Profiling miRNA expression in cells that directly contribute to human disease pathogenesis is likely to aid the discovery of novel drug targets and biomarkers. However, tissue heterogeneity and the limited amount of human diseased tissue available for research purposes present fundamental difficulties that often constrain the scope and potential of such studies. We established a flow cytometry-based method for isolating pure populations of pathogenic T cells from bronchial biopsy samples of asthma patients, and optimized a high-throughput nano-scale qRT-PCR method capable of accurately measuring 96 miRNAs in as little as 100 cells.

Negative social reaction to strabismus in school children ages 8-12 years.

Purpose: To investigate children's willingness to sit next to a child with noticeable exotropia as a measure of social alienation.

Methods: This was a cross-sectional, mixed-design study. Children in primary grades 3-6 (8-12 years old) were asked to view 8 digitally modified images of exotropic or orthotropic children in classroom settings and rate their willingness to sit next to the child in each image.
