RESUMO

OBJECTIVE: Competencies related to diversity could be essential to training and assessing student pharmacists in their readiness to provide equitable and inclusive care. Such competencies are lacking in pharmacy education; therefore, this study aimed to explore the development of diversity competencies and supporting factors needed to prepare students to meet the competencies and provide patient care in a diverse, equitable, and inclusive manner. METHODS: Pharmacy diversity thought leaders were invited to participate in a 3-round modified Delphi survey. Survey items were created using a Backward Design. Qualitative data were analyzed using the Constant Comparative Method. Draft competency statements were created based on the collective comments from Round 1 along with themes related to the supporting factors needed to achieve the competencies. Consensus on themes, competency statements, and edits were identified in Round 2. Additional comments and feedback on edits were gathered in Round 3. Consensus was preset at 85.7%. RESULTS: Seven competency statements were created. Knowledge, skills, attitudes, behaviors, values, curricular content/pedagogy, and resources needed to prepare students to meet the competencies and support faculty would need were identified. CONCLUSION: Preliminary diversity competencies and supporting factors needed were developed using the perspective of thought leaders. Further evaluation, including the development of student-appropriate competencies, testing and validation of content and assessment tools, and determining place in the pharmacy curriculum, are future steps that should be considered in the competency development process.

RESUMO

Introduction: Without explicit education and training on how social determinants of health (SDoH) impact patient care and health outcomes, medical schools are failing to effectively equip future physicians to serve their patients. We created this workshop on health equity with a focus on SDoH to help students more effectively communicate with diverse populations. Methods: Third-year medical students and faculty were provided with class guides, learning objectives, role-play vignettes containing clerkship-specific history and physical exams, schedules, and discussion questions during a 2-hour session centered on SDoH. The workshop's impact was measured through mixed-methods analysis of surveys. Results: Based on pre- and postsurvey results from 87 participants, medical students strongly agreed that (1) SDoH factor more into a patient's health outcomes than the clinical encounter (pre: 67%, post: 87%), (2) it is their duty to gather information about SDoH (pre: 86%, post: 97%), (3) neighborhood safety is one of the key SDoH (pre: 88%, post: 97%), (4) they understood the impact of upstream interventions (pre: 35%, post: 93%), (5) they could efficiently screen all patients for SDoH at every medical encounter (pre: 27%, post: 86%), and (6) they could find preliminary resources to quickly assist patients in need of help regarding particular SDoH (pre: 26%, post: 85%). Discussion: This was the first iteration of this workshop; challenges involved piloting the content, time restraints, and organizational structure of the workshop design. Future directions include making SDoH curricula an integral part of undergraduate medical education and diverse clinical environments.

RESUMO

Introduction: Community partnership is a key strategy for addressing the social determinants of health and achieving health equity. There are few examples of curricula for undergraduate medical education that teach all, rather than self-selected, medical students to collaborate with community members to improve health. We describe the design and implementation of the Community Health Advocacy Initiative (CHAI) curriculum, a new yearlong educational program for medical students at Northwestern University's Feinberg School of Medicine. Methods: CHAI aimed to fill the curricular gap in social determinants of health education by providing medical students with the knowledge and skills to improve the health of patients through collaborations with community partners. This longitudinal curriculum included structured faculty mentorship and an applied community experience. Results: The CHAI curriculum was delivered to 164 second-year medical students in academic year 2021-2022. Faculty mentors rated most students as meeting expectations for application of community partnership principles and demonstration of professionalism. Qualitative analysis of faculty mentor comments demonstrated that medical students exhibited positive outcomes in engaging with community organizations, overcoming barriers, developing feasible and impactful goals, and advancing their own knowledge and skills. Discussion: Implementing a community health curriculum for all medical students is feasible and represents an important model for teaching about the importance of community partnerships in addressing the social determinants of health.

RESUMO

Introduction: The influence of implicit biases in virtual interviews must be addressed to ensure equity within the admissions process. ABATE is a mnemonic framework of five specific categories of implicit bias (affinity-based, backdrop-based, appearance-based, technology and media-based, and enunciation-based biases) that should be anticipated and mitigated for faculty, staff, health professionals, and medical students who conduct virtual interviews at medical schools. Methods: A 60-minute workshop was developed to educate medical school admissions interviewers about the ABATE model and strategies to mitigate implicit bias during virtual interviews. Four workshops were held over 1 year totaling 217 individual attendees. The workshops were evaluated using a single-group, pre-post questionnaire designed with the Kirkpatrick evaluation model. Results: Attendees reported that they found the ABATE workshop useful and relevant to improving their ability to minimize implicit bias during virtual interviews. Significant improvements were found in attendee reactions to the utility of implicit bias training (M pre = 2.6, M post = 3.1, p = .002). Significant changes were also reported in attendees' attitudes about interviewing confidence (M pre = 3.0, M post = 3.2, p = .04), bias awareness (M pre = 3.0, M post = 3.4, p = .002), and identifying and applying bias mitigation solutions (M pre = 2.5, M post = 3.0, p = .003). Knowledge specific to backdrop-based biases also significantly increased (M pre = 3.2, M post = 3.4, p = .04). Discussion: The ABATE workshop demonstrates promise in mitigating implicit bias in virtual medical school interviews.

RESUMO

Introduction: Medical schools seeking to correct and reform curricula towards anti-racist perspectives need to address anti-Black forms of racism specifically and teach students critical upstander skills to interrupt manifestations of racism. We developed a course to teach preclinical medical students basic anti-racism competencies including recognition and awareness of anti-Black racism in medicine and upstander skills to advocate for patients and colleagues. Methods: In 2021 and 2022, we designed, implemented, and evaluated an elective course for second-year medical students (N = 149) to introduce competencies of anti-racism focusing on upstander skills for addressing anti-Blackness. We designed three patient cases and one student-centered case to illustrate manifestations of anti-Black racism in medicine and used these cases to stimulate small-group discussions and guide students toward recognizing and understanding ways of responding to racism. We designed pre- and postassessments to evaluate the effectiveness of the course and utilized anonymous feedback surveys. Results: Participants showed significant improvement in pre- to postassessment scores in both years of the course. The anonymous feedback survey showed that 97% of students rated the course at least somewhat effective, and the qualitative responses revealed five core themes: course timing, case complexity, learner differentiation, direct instruction, and access to resources. Discussion: This course reinforces upstander competencies necessary for advancing anti-racism in medicine. It addresses a gap in medical education by reckoning with the entrenched nature of anti-Black racism in the culture of medicine and seeks to empower undergraduate medical students to advocate for Black-identifying patients and colleagues.

RESUMO

Objectives: The aim of this study was to assess the completeness and readability of generative pre-trained transformer-4 (GPT-4)-generated discharge instructions at prespecified reading levels for common pediatric emergency room complaints. Materials and Methods: The outputs for 6 discharge scenarios stratified by reading level (fifth or eighth grade) and language (English, Spanish) were generated fivefold using GPT-4. Specifically, 120 discharge instructions were produced and analyzed (6 scenarios: 60 in English, 60 in Spanish; 60 at a fifth-grade reading level, 60 at an eighth-grade reading level) and compared for completeness and readability (between language, between reading level, and stratified by group and reading level). Completeness was defined as the proportion of literature-derived key points included in discharge instructions. Readability was quantified using Flesch-Kincaid (English) and Fernandez-Huerta (Spanish) readability scores. Results: English-language GPT-generated discharge instructions contained a significantly higher proportion of must-include discharge instructions than those in Spanish (English: mean (standard error of the mean) = 62% (3%), Spanish: 53% (3%), P = .02). In the fifth-grade and eighth-grade level conditions, there was no significant difference between English and Spanish outputs in completeness. Readability did not differ across languages. Discussion: GPT-4 produced readable discharge instructions in English and Spanish while modulating document reading level. Discharge instructions in English tended to have higher completeness than those in Spanish. Conclusion: Future research in prompt engineering and GPT-4 performance, both generally and in multiple languages, is needed to reduce potential for health disparities by language and reading level.

RESUMO

The present study aims to test a model in which basic psychological needs (BPN) satisfaction in physical-sport activity contexts is associated with self-determined motivation, which, in turn, would predict the social inclusion of people with intellectual disabilities. A total of 286 people with intellectual disabilities (53.5% men) who reported engaging in physical-sport activities responded to a validated questionnaire about the satisfaction of their BPN, motivation (using the Self-determination index [SDI]), and social inclusion. A Pearson's bivariate correlation and structural equation modeling were conducted. The resulting model was reanalyzed in a multigroup analysis to test its invariance across self and proxy reports. Positive associations were found between the satisfaction of the BPN and the SDI. However, the SDI and social inclusion were positively associated only in proxy reports (ßself = 0.07 vs. ßproxy = 0.30). The tested model established positive relationships between the BPN and SDI in autonomy (ßself = 0.21 vs. ßproxy = 0.18), competence (ßself = 0.47 vs. ßproxy = 0.53), and relatedness (ßself = 0.21 vs. ßproxy = 0.23). Further research is needed to understand the factors leading to discrepancies between participants and proxies when relating the SDI to social inclusion in the context of physical-sport activity. However, the results obtained suggest that it would be optimal to develop contexts of practice for people with intellectual disabilities in which the satisfaction of their BPN is favored and that this has a positive impact on their motivation and social inclusion.

RESUMO

Introduction: The increased focus among researchers and professionals on participation as an explicit intervention outcome has prompted a paradigm shift in both thought and practice. However, much research centers on altering participation outcomes in specific life situations and stages. This discussion paper considers "participation as a means" in pediatric rehabilitation and special education interventions, emphasizing its role in achieving lasting outcomes. Method: This paper uses a Venn diagram approach to consider relations between three core concepts-participation, intervention, and outcomes-and their intersection. The paper's central theme revolves around the intersection of these concepts, wherein participation serves as a means to achieve enduring participation outcomes within the realms of rehabilitation and special education. The discussion is supported by contemporary empirical work and from literature identified in two recent scoping reviews focusing on the intervention process. Results: Achieving enduring participation outcomes through participation in the intervention process necessitates creating a learning experience, with children and families actively participating in every step: identifying participation issues, seeking explanations, prioritizing intervention goals, selecting methods, implementing interventions, and evaluating the process and outcomes. Discussion: This structured approach supports professionals and researchers to foster the skills and capacity required for lasting participation outcomes for children with impairments.

RESUMO

Funders of research have an opportunity to advance health equity and social justice by incorporating principles of diversity, equity, inclusion, and justice (DEIJ) in their approach to grantmaking. We conducted a pragmatic review to identify opportunities for grantmakers in the health care sector to integrate DEIJ in their funding activities. The resulting framework discusses recommendations within three phases as follows: (1) Organizational Context (i.e., initiate DEIJ efforts within the grantmaking organization, invest in community partnerships, and establish DEIJ goals), (2) Grantmaking Process (i.e., DEIJ-specific practices related to grant design, application, proposal review processes, and support for grantees), and (3) Assessment of Process and Outcomes (i.e., measurement, evaluation, and dissemination to maximize impact of DEIJ efforts). Throughout all grantmaking phases, it is critical to partner with and engage individuals and communities that have been historically marginalized in health care and research. In this article, we describe how adoption of framework practices can leverage grantmaking to advance DEIJ for communities, researchers, and projects.

RESUMO

BACKGROUND: The COVID-19 pandemic significantly transformed the landscape of work and collaboration, impacting design research methodologies and techniques. Co-design approaches have been both negatively and positively affected by the pandemic, prompting a need to investigate and understand the extent of these impacts, changes, and adaptations, specifically in the health sector. Despite the challenges that the pandemic imposed on conducting co-design and related projects, it also encouraged a re-evaluation of co-design practices, leading to innovative solutions and techniques. Designers and researchers have explored alternative ways to engage stakeholders and end users, leveraging digital workshops and participatory digital platforms. These adaptations have the potential to enhance inclusivity, allowing for a wider range of individuals to contribute their perspectives and insights through co-design and thus contribute to healthcare change. OBJECTIVE: This study aims to explore the impacts of the pandemic on co-design and related practices, focusing on co-design practices in healthcare that have been gained, adapted, or enhanced, with a specific focus on issues of equity, diversity, and inclusion. METHODS: The study uses a realist synthesis methodology to identify and analyze the effects of the pandemic on co-design approaches in health, drawing on a range of sources including first-person experiences, gray literature, and academic literature. A community of practice in co-design in health will be engaged to support this process. RESULTS: By examining the experiences and insights of professionals, practitioners, and communities who were actively involved in co-design and have navigated the challenges and opportunities of the pandemic, we can gain a deeper understanding of the strategies, tools, and techniques that have facilitated effective co-design during the pandemic, contributing to building resilience and capacity in co-design in health beyond the pandemic. CONCLUSIONS: By involving community partners, community of practice (research), and design practitioners, we expect closer proximity to practice with capacity building occurring through the realist process, thus enabling rapid adoption and refinement of new techniques or insights that emerge. Ultimately, this research will contribute to the advancement of co-design methodologies and inform the future of co-design in health.

RESUMO

Wild birds harbour a vast diversity of adenoviruses that remain uncharacterised with respect to their genome organisation and evolutionary relatedness within complex host ecosystems. Here, we characterise a novel adenovirus type within Aviadenovirus genus associated with severe necrotising hepatitis in a captive Timneh grey parrot, tentatively named as Timneh grey parrot adenovirus 1 (TpAdV-1). The TpAdV-1 genome is 39,867 bp and encodes 46 putative genes with seven hitherto not described ones. Comparative genomics and phylogenetic analyses revealed highest nucleotide identity with psittacine adenovirus 1 and psittacine adenovirus 4 that formed a discrete monophyletic clade within Aviadenovirus lineage suggesting a deep host co-divergent lineage within Psittaciformes hosts. Several recombination breakpoints were identified within the TpAdV-1 genome, which highlighted an ancient evolutionary relationship across the genera Aviadenovirus, Mastadenovirus and Atadenovirus. This study hints towards a host-adapted sub-lineage of avian adenovirus capable of having significant host virulence in Psittaciformes birds augmented with ecological opportunity.

RESUMO

BACKGROUND: Black individuals are historically underrepresented in oncology clinical trials. One potential reason for this is the prevalence of kidney disease in Black individuals, utilization of estimated creatinine clearance as a surrogate for glomerular filtration rate (GFR) in oncology, and GFR-based trial eligibility criteria. We characterized the representation of racial minorities in anticancer agent pivotal trials and examined if GFR-based trial eligibility criteria impact the proportion of Black individuals in trial populations. METHODS: We constructed a data repository for anticancer drugs FDA-approved 2015-2019 and associated pivotal trials, from which we extracted trial population racial compositions and GFR-based trial eligibility criteria. We calculated the participation-to-incidence ratio (PIR) and participation-to-mortality ratio (PMR) for a variety of cancer sites, where PIR or PMR >1.2 and < 0.8 indicate overrepresentation and underrepresentation, respectively. We evaluated the relationship between GFR eligibility cutoffs and the proportion of Black enrollees with Spearman rank correlation coefficient. RESULTS: We assessed 24,698 patients in 74 trials. Black individuals were underrepresented in all trials (PIR ≤0.48, PMR ≤0.50). For trials with GFR-based eligibility criteria (n = 49), a lower GFR cutoff was modestly associated with a higher proportion of Black enrollees (r = -0.29, p = 0.039). This relationship was strengthened for trials that only used estimated creatinine clearance to estimate GFR (r = -0.43, p = 0.004). CONCLUSIONS: GFR-related eligibility, and specifically the use of estimated creatinine clearance, may contribute to Black individuals being disproportionately excluded from cancer clinical trials. This highlights the need for implementation of contemporary GFR equations and other interventions to boost racial minority trial enrollment.

RESUMO

OBJECTIVE: Understanding and quantifying biases when designing and implementing actionable approaches to increase fairness and inclusion is critical for artificial intelligence (AI) in biomedical applications. METHODS: In this Special Communication, we discuss how bias is introduced at different stages of the development and use of AI applications in biomedical sciences and health care. We describe various AI applications and their implications for fairness and inclusion in sections on 1) Bias in Data Source Landscapes, 2) Algorithmic Fairness, 3) Uncertainty in AI Predictions, 4) Explainable AI for Fairness and Equity, and 5) Sociological/Ethnographic Issues in Data and Results Representation. RESULTS: We provide recommendations to address biases when developing and using AI in clinical applications. CONCLUSION: These recommendations can be applied to informatics research and practice to foster more equitable and inclusive health care systems and research discoveries.

RESUMO

The Twangiza-Namoya Gold Deposit within the Kibaran Belt of the Democratic Republic of the Congo represents a crucial manifestation of the hydrothermal gold system. This review investigates its intricate origin and the subsequent metallogenic evolution that has shaped its present-day characteristics and offers a systematic categorization based on its deposition processes and geotectonic settings. The findings reveal that the gold deposits are predominantly derived from sedimentary fluid sources. Within this vast metallogenic province, two stages of gold deposition have been constrained: (a) the early-stage formation related to the accretion of Rodinia assembly with subduction-collisional event where diagenesis cemented the syngenetic pyrite carbonaceous sediments and (b) the later stage deposition related to the continent-collisional event during the last stage of Rodinia supercontinent amalgamation. Previous isotopic investigations, with a particular emphasis on pyrite sulfur isotopes on both host rocks and vein-bearing sulfides, have been instrumental in tracing the origins of gold-bearing fluids in the study region. The isotopic variance in the four deposits: Twangiza (-5.2 % to +3 %, avg. -0.3 %), Kamituga (-0.6 % to -0.9.1 %, avg. -5%), Lugushwa (+3.0 % to -18.4 %), and Namoya, on the southernmost end, has a vast range but with much heavier isotope compositions, ranging between +1.3 % and to +22.6 %, with an average of +12.2 %. The data predominantly points to the sedimentary origins of ore fluids in the Twangiza-Namoya Gold belt, highlighting the pivotal role of sedimentary processes in shaping the metallogenic landscape of the region. The fluids inclusions depicted the deposits to be formed from H2O-Nacl-H2O with abundant CH4 and N2 ore-forming fluid, moderate temperature (350-500 °C), and low salinity. The overall results confirm the genetic style of the Twangiza-Namoya Gold Belt to be an orogenic gold-style deposit that was emplaced during the early Neoproterozoic era in low greenschist facies terrain.

RESUMO

We address the ethical implications of training and becoming family therapists in the United States when considering the colonial control and management of knowledge by the westernized institutionalized university. We do so decolonially. Through the work of decolonial thinkers, doers, and sensers, we center our discussion on the heteropatriarchal Eurocentric institutionalization of knowledge linked to the development and sustainability of structures of family therapy training through racialization and monetization. We discuss a decolonial understanding of race in relation to the liberalized politics of diversity, equity, and inclusion and upward mobility of family therapy education. Most importantly, we reflect upon the possibilities of reexistence within family therapy, fissuring the colonial structures of training tuition-based family therapists. We locate those possibilities through practices of crack-making, epistemic insurgence, and mischief. Our discussions and reflections are developed throughout by thinking, sensing, and speaking decolonially, storying our racialized incarnated lives from the saberes, ज्ञान, rhythms, vapors, or tastes of our communities, displaced by the European cannon. We embrace a decolonial pedagogy of learning without teaching, positioning family therapy education as a site for sociopolitical struggle and action toward possibilities of reexistence.

RESUMO

The identification of slag inclusion defects in welds is of the utmost importance in guaranteeing the integrity, safety, and prolonged service life of welded structures. Most research focuses on different kinds of weld defects, but branch research on categories of slag inclusion material is limited and critical for safeguarding the quality of engineering and the well-being of personnel. To address this issue, we design a simulated method using ultrasonic testing to identify the inclusion of material categories in austenitic stainless steel. It is based on a simulated experiment in a water environment, and six categories of cubic specimens, including four metallic and two non-metallic materials, are selected to simulate the slag materials of the inclusion defects. Variational mode decomposition optimized by particle swarm optimization is employed for ultrasonic signals denoising. Moreover, the phase spectrum of the denoised signal is utilized to extract the phase characteristic of the echo signal from the water-slag specimen interface. The experimental results show that our method has the characteristics of appropriate decomposition and good denoising performance. Compared with famous signal denoising algorithms, the proposed method extracted the lowest number of intrinsic mode functions from the echo signal with the highest signal-to-noise ratio and lowest normalized cross-correlation among all of the comparative algorithms in signal denoising of weld slag inclusion defects. Finally, the phase spectrum can ascertain whether the slag inclusion is a thicker or thinner medium compared with the weld base material based on the half-wave loss existing or not in the echo signal phase.

RESUMO

The paper investigates a problem concerning the equilibrium of a solid body containing a thin rigid inclusion and a crack. It is assumed that the body is hyperelastic, therefore, it is described within the framework of finite strain theory. One of the peculiarities of this problem is a global injectivity constraint, which prevents the body, the crack faces and the inclusion from both mutual and self penetration. First, the paper deals with the differential formulation of the problem. Next, we consider energy minimization, showing that the latter provides the weak formulation of the former. Finally, the existence of the weak solution is demonstrated through the use of the variational technique.This article is part of the theme issue 'Non-smooth variational problems with applications in mechanics'.
