RESUMO

BACKGROUND: The Racial Equity Coalition (REC) formed to address persistent educational disparities. The coalition was composed of 14 Black, Indigenous and People of Color (BIPOC) organizations that provide culturally integrative youth services. OBJECTIVES: REC, with support from United Way of King County, engaged in participatory research to identify commonalities and shared struggles to inform collective action. Participatory research aligns with REC's commitment to equitable participatory processes. This article focuses on REC's experiences with funders. The objective was to understand what creates positive and challenging experiences with funders, and to identify recommendations for funders to become more culturally responsive. METHODS: A research committee was formed including representatives of nine REC organizations and United Way of King County staff. The committee conducted interviews with each of the 14 REC organizations and conducted thematic analysis of interview transcripts. Through participatory analysis, the committee drafted narratives that were further refined through a series of research retreats attended by all REC organizations. RESULTS: Recommendations were to incentivize collaboration, listen to communities to create culturally responsive definitions of success and measurement strategies, arrive at mutually agreed upon approaches with organizations, honor the connections BIPOC organizations have with their communities, and provide unrestricted funding to allow BIPOC organizations greater agency. CONCLUSIONS: A major challenge for BIPOC organizations is navigating White dominant culture that too often shows up in funding requirements. Having to fit dominant culture standards stifles BIPOC organizations' abilities to meet community needs and the responsiveness of their approaches. REC identified recommendations for funders to be more culturally responsive and community centered.

RESUMO

Recently, multiple chimeric antigen receptor T-cell (CAR-T)-based therapies have been approved for treating hematological malignancies, targeting CD19 and B-cell maturation antigen. Unlike protein or antibody therapies, CAR-T therapies are "living cell" therapies whose pharmacokinetics are characterized by expansion, distribution, contraction, and persistence. Therefore, this unique modality requires a different approach for quantitation compared with conventional ligand binding assays implemented for most biologics. Cellular (flow cytometry) or molecular assays (polymerase chain reaction (PCR)) can be deployed with each having unique advantages and disadvantages. In this article, we describe the molecular assays utilized: quantitative PCR (qPCR), which was the initial platform used to estimate transgene copy numbers and more recently droplet digital PCR (ddPCR) which quantitates the absolute copy numbers of CAR transgene. The comparability of the two methods in patient samples and of each method across different matrices (isolated CD3+ T-cells or whole blood) was also performed. The results show a good correlation between qPCR and ddPCR for the amplification of same gene in clinical samples from a CAR-T therapy trial. In addition, our studies show that the qPCR-based amplification of transgene levels was well-correlated, independent of DNA sources (either CD3+ T-cells or whole blood). Our results also highlight that ddPCR can be a better platform for monitoring samples at the early phase of CAR-T dosing prior to expansion and during long-term monitoring as they can detect samples with very low copy numbers with high sensitivity, in addition to easier implementation and sample logistics.

RESUMO

Fluid shear stress (FSS) is an important parameter that regulates various cell functions such as proliferation and migration. While there are a number of techniques to generate FSSin vitro, many of them require physical deformation or movement of solid objects to generate the fluid shear, making it difficult to decouple the effects of FSS and mechanical strains. This work describes the development of a non-mechanical means to generate fluid flow and FSS in a 2Din vitrosetting. This was accomplished with a magnetohydrodynamic (MHD) pump, which creates liquid flow by generating a Lorentz force through the interaction between an electric field and an orthogonal magnetic field. The MHD pump system presented here consisted of trapezoidal prism-shaped magnets, a pair of platinum electrodes, and a modified petri dish. The system was validated and tested on anin vitrowound model, which is based on analyzing the migration of fibroblast cells through an artificially created scratch on a confluent cell culture surface. Experiments were performed to a control group, an electric field only group, and a group that was subject to fluid flow with the application of both electric field and magnetic field. Results show that fibroblast cells that experienced fluid shear have higher wound closure rate compared to the control group and the electric field only group. The data shows that the MHD pump can be a great tool to study FSSin vitro. Furthermore, due to its fluid flow generation without mechanical force, this system can be adapted and implemented to study the role of FSS and electric field on wound healingin vivo.

RESUMO

INTRODUCTION: This study aims to describe adherence rates to the 2014 American Academy of Pediatrics (AAP) Committee on Infectious Disease guidance document recommending which patients should receive palivizumab for prophylaxis against respiratory syncytial virus (RSV). METHODS: A retrospective, single-center analysis of patients who received at least one dose of palivizumab between October 1, 2012, and March 1, 2017 was conducted. Data collected included demographics, medical history, palivizumab administration regimens, and incidence of RSV infection. RESULTS: Data were collected on 457 patients who received palivizumab over five RSV seasons. Approximately half of the patients (45% and 55%, respectively) received palivizumab according to the AAP recommendations in place at the time (2012 or 2014 recommendations, respectively). One percent of patients had a breakthrough RSV infection after receiving at least one dose of palivizumab. There was no significant difference in the number of breakthrough infections before and after the 2014 recommendations were released (3 vs. 2). CONCLUSIONS: Approximately half of the patients received prophylaxis in accordance with the 2014 AAP recommendations and infrequently suffered from a breakthrough RSV infection.

RESUMO

OBJECTIVES: We systematically reviewed the Environmental Protection Agency, National Center for Environmental Research's (NCER's) requests for applications (RFAs) and identified strategies that NCER and other funders can take to bolster community engagement. METHODS: We queried NCER's publically available online archive of funding opportunities from fiscal years 1997 to 2013. From an initial list of 211 RFAs that met our inclusion criteria, 33 discussed or incorporated elements of community engagement. We examined these RFAs along 6 dimensions and the degree of alignments between them. RESULTS: We found changes over time in the number of RFAs that included community engagement, variations in how community engagement is defined and expected, inconsistencies between application requirements and peer review criteria, and the inclusion of mechanisms supporting community engagement in research. CONCLUSIONS: The results inform a systematic approach to developing RFAs that support community engagement in research.

RESUMO

A growing number of community-based organizations and community-academic partnerships are implementing processes to determine whether and how health research is conducted in their communities. These community-based research review processes (CRPs) can provide individual and community-level ethics protections, enhance the cultural relevance of study designs and competence of researchers, build community and academic research capacity, and shape research agendas that benefit diverse communities. To better understand how they are organized and function, representatives of 9 CRPs from across the United States convened in 2012 for a working meeting. In this article, we articulated and analyzed the models presented, offered guidance to communities that seek to establish a CRP, and made recommendations for future research, practice, and policy.
