Les points de vue des étudiants en médecine autochtones sur une voie d’admission au programme postdoctoral réservée aux candidats autochtones

Objective: The objective of this study is to assess the perceptions of Indigenous medical students on postgraduate admissions through an Indigenous admissions pathway (IAP), and to determine what factors may influence Indigenous medical students’ choice of residency training program.       Methods: We distributed a survey to self-identified Indigenous students at settler Canadian medical schools. The survey questioned the students’ acceptability of an IAP, and what factors would influence application through an IAP. Analysis included descriptive statistics and thematic analysis of open-ended questions. Results: Thirty-six participants responded to the survey. Location and proximity to family or support system were the most important factors in choosing a residency program. Participants identified mentorship from Indigenous physicians and community involvement as being important features of a residency program that has an IAP. Eighty-one percent of participants felt the availability of an IAP would influence their choice of residency program. Fear of judgement or stigma, concern about entrance requirements, and program logistics were identified as barriers to applying to residency through an IAP. All participants believed that an IAP would have a positive influence on the healthcare system more broadly. Conclusions: An IAP appears to be an acceptable residency application format to Indigenous students but cannot exist in isolation. It is important for programs to consider the needs and safety of Indigenous trainees within residency programs. Objectif : L’objectif de cette étude est d’interroger les perceptions des étudiants en médecine autochtones d’une voie d’admission aux études postdoctorales réservée aux candidats autochtones et de relever les facteurs qui influenceraient leur choix de programme de résidence. Méthodes : Nous avons fait parvenir un questionnaire aux étudiants inscrits dans les facultés de médecine canadiennes qui se définissent comme Autochtones. L’enquête portait sur l’acceptabilité par les étudiants d’un programme d’admission pour candidats autochtones (PACA) et sur les facteurs qui influenceraient leur choix de poser leur candidature dans le cadre d’un PACA. L’examen portait sur des statistiques descriptives et sur une analyse thématique de questions ouvertes. Résultats : Trente-six participants ont répondu à l’enquête. Le lieu et la proximité de la famille ou du réseau de soutien ressortent comme les facteurs les plus importants dans le choix d’un programme de résidence. Ils attachent également de l’importance à la présence de mentorat de la part de médecins autochtones et à la participation de la communauté dans le cadre d’un programme de résidence et par conséquent ils voient un intérêt à ce qu’un tel programme soit accessible par le biais d’un PACA. Quatre-vingt-un pour cent des participants ont estimé que la présence d’un PACA influencerait leur choix de programme de résidence. La crainte d’être jugé ou stigmatisé, l’inquiétude par rapport aux conditions d’admission et la logistique du programme ont été identifiées comme des obstacles à la présentation d’une demande de résidence dans le cadre d’un PACA. Ils sont unanimes quant à l’influence positive d’un tel programme sur le système de soins de santé en général. Conclusions : Les étudiants autochtones trouvent la formule d’une voie d’admission à la résidence réservée aux candidats autochtones acceptable, à condition qu’elle ne soit pas un élément isolé et qu’on tienne compte des besoins et de la sécurité des étudiants dans le cadre des programmes de résidence eux-mêmes

STEM through Authentic Research and Training Program (START) for Underrepresented Communities: Adapting to the COVID-19 Pandemic

The STEM Through Authentic Research and Training (START) Program is a new program integrating academic, social, and professional experiences, in the theme of exomedicine, to build a pipeline into college for first generation and traditionally underrepresented students by providing year-round authentic opportunities and professional development for high school students and teachers. In response to the COVID-19 pandemic, the START Program has worked with the local Fayette County public school and community partners to provide content to over 300 students through: virtual laboratory tours with community partner Space Tango, meet a scientist discussions, and online near-peer student demonstrations aimed at making the practice of STEM disciplines approachable. Furthermore, the START Program has partnered with Higher Orbits to provide at-home, space-themed learning kits for students to develop teamwork, communication, and STEM principles while engaging in online content with teachers, professionals, and astronauts. Finally, the START Program has moved its training platforms online, including receiving College Reading and Learning Association (CRLA) Peer Educator accreditation for our near-peer mentoring and coaching training. As a result, the START Program is better positioned to address this critical need in STEM education, while reaching more students in the community than possible with face-to-face interactions alone

Nitric oxide production and antioxidant function during viral infection of the coccolithophore Emiliania huxleyi

Emiliania huxleyi is a globally important marine phytoplankton that is routinely infected by viruses. Understanding the controls on the growth and demise of E. huxleyi blooms is essential for predicting the biogeochemical fate of their organic carbon and nutrients. In this study, we show that the production of nitric oxide (NO), a gaseous, membrane-permeable free radical, is a hallmark of early-stage lytic infection in E. huxleyi by Coccolithoviruses, both in culture and in natural populations in the North Atlantic. Enhanced NO production was detected both intra- and extra-cellularly in laboratory cultures, and treatment of cells with an NO scavenger significantly reduced viral production. Pre-treatment of exponentially growing E. huxleyi cultures with the NO donor S-nitroso-N-acetylpenicillamine (SNAP) prior to challenge with hydrogen peroxide (H2O2) led to greater cell survival, suggesting that NO may have a cellular antioxidant function. Indeed, cell lysates generated from cultures treated with SNAP and undergoing infection displayed enhanced ability to detoxify H2O2. Lastly, we show that fluorescent indicators of cellular ROS, NO, and death, in combination with classic DNA- and lipid-based biomarkers of infection, can function as real-time diagnostic tools to identify and contextualize viral infection in natural E. huxleyi blooms

Rethinking First Language–Second Language Similarities and Differences in English Proficiency: Insights From the ENglish Reading Online (ENRO) Project

This article presents the ENglish Reading Online (ENRO) project that offers data on English reading and listening comprehension from 7,338 university-level advanced learners and native speakers of English representing 19 countries. The database also includes estimates of reading rate and seven component skills of English, including vocabulary, spelling, and grammar, as well as rich demographic and language background data. We first demonstrate high reliability for ENRO tests and their convergent validity with existing meta-analyses.We then provide a bird’s-eye view of first (L1) and second (L2) language comparisons and examine the relative role of various predictors of reading and listening comprehension and reading speed. Across analyses, we found substantially more overlap than differences between L1 and L2 speakers, suggesting that English reading proficiency is best considered across a continuum of skill, ability, and experiences spanning L1 and L2 speakers alike. We end by providing pointers for how researchers can mine ENRO data for future studies

Proceedings of the 3rd Biennial Conference of the Society for Implementation Research Collaboration (SIRC) 2015: advancing efficient methodologies through community partnerships and team science

It is well documented that the majority of adults, children and families in need of evidence-based behavioral health interventionsi do not receive them [1, 2] and that few robust empirically supported methods for implementing evidence-based practices (EBPs) exist. The Society for Implementation Research Collaboration (SIRC) represents a burgeoning effort to advance the innovation and rigor of implementation research and is uniquely focused on bringing together researchers and stakeholders committed to evaluating the implementation of complex evidence-based behavioral health interventions. Through its diverse activities and membership, SIRC aims to foster the promise of implementation research to better serve the behavioral health needs of the population by identifying rigorous, relevant, and efficient strategies that successfully transfer scientific evidence to clinical knowledge for use in real world settings [3]. SIRC began as a National Institute of Mental Health (NIMH)-funded conference series in 2010 (previously titled the “Seattle Implementation Research Conference”; $150,000 USD for 3 conferences in 2011, 2013, and 2015) with the recognition that there were multiple researchers and stakeholdersi working in parallel on innovative implementation science projects in behavioral health, but that formal channels for communicating and collaborating with one another were relatively unavailable. There was a significant need for a forum within which implementation researchers and stakeholders could learn from one another, refine approaches to science and practice, and develop an implementation research agenda using common measures, methods, and research principles to improve both the frequency and quality with which behavioral health treatment implementation is evaluated. SIRC’s membership growth is a testament to this identified need with more than 1000 members from 2011 to the present.ii SIRC’s primary objectives are to: (1) foster communication and collaboration across diverse groups, including implementation researchers, intermediariesi, as well as community stakeholders (SIRC uses the term “EBP champions” for these groups) – and to do so across multiple career levels (e.g., students, early career faculty, established investigators); and (2) enhance and disseminate rigorous measures and methodologies for implementing EBPs and evaluating EBP implementation efforts. These objectives are well aligned with Glasgow and colleagues’ [4] five core tenets deemed critical for advancing implementation science: collaboration, efficiency and speed, rigor and relevance, improved capacity, and cumulative knowledge. SIRC advances these objectives and tenets through in-person conferences, which bring together multidisciplinary implementation researchers and those implementing evidence-based behavioral health interventions in the community to share their work and create professional connections and collaborations

31st Annual Meeting and Associated Programs of the Society for Immunotherapy of Cancer (SITC 2016) : part two

Background The immunological escape of tumors represents one of the main ob- stacles to the treatment of malignancies. The blockade of PD-1 or CTLA-4 receptors represented a milestone in the history of immunotherapy. However, immune checkpoint inhibitors seem to be effective in specific cohorts of patients. It has been proposed that their efficacy relies on the presence of an immunological response. Thus, we hypothesized that disruption of the PD-L1/PD-1 axis would synergize with our oncolytic vaccine platform PeptiCRAd. Methods We used murine B16OVA in vivo tumor models and flow cytometry analysis to investigate the immunological background. Results First, we found that high-burden B16OVA tumors were refractory to combination immunotherapy. However, with a more aggressive schedule, tumors with a lower burden were more susceptible to the combination of PeptiCRAd and PD-L1 blockade. The therapy signifi- cantly increased the median survival of mice (Fig. 7). Interestingly, the reduced growth of contralaterally injected B16F10 cells sug- gested the presence of a long lasting immunological memory also against non-targeted antigens. Concerning the functional state of tumor infiltrating lymphocytes (TILs), we found that all the immune therapies would enhance the percentage of activated (PD-1pos TIM- 3neg) T lymphocytes and reduce the amount of exhausted (PD-1pos TIM-3pos) cells compared to placebo. As expected, we found that PeptiCRAd monotherapy could increase the number of antigen spe- cific CD8+ T cells compared to other treatments. However, only the combination with PD-L1 blockade could significantly increase the ra- tio between activated and exhausted pentamer positive cells (p= 0.0058), suggesting that by disrupting the PD-1/PD-L1 axis we could decrease the amount of dysfunctional antigen specific T cells. We ob- served that the anatomical location deeply influenced the state of CD4+ and CD8+ T lymphocytes. In fact, TIM-3 expression was in- creased by 2 fold on TILs compared to splenic and lymphoid T cells. In the CD8+ compartment, the expression of PD-1 on the surface seemed to be restricted to the tumor micro-environment, while CD4 + T cells had a high expression of PD-1 also in lymphoid organs. Interestingly, we found that the levels of PD-1 were significantly higher on CD8+ T cells than on CD4+ T cells into the tumor micro- environment (p < 0.0001). Conclusions In conclusion, we demonstrated that the efficacy of immune check- point inhibitors might be strongly enhanced by their combination with cancer vaccines. PeptiCRAd was able to increase the number of antigen-specific T cells and PD-L1 blockade prevented their exhaus- tion, resulting in long-lasting immunological memory and increased median survival

CrossFit Training Improvements in Sport Performance and Body Composition in Young Healthy Adults

Color poster with text, tables, graphs, and images.CrossFit training, which includes a variety of exercise training modes (e.g., aerobic endurance training; strength, power, and speed training; and flexibility, agility, balance, and coordination training) merged into a single high intensity, short duration workout. It has gained significant popularity recently, but there is limited data on its potential health and fitness benefits. Therefore, the purpose of this study was to determine if four weeks of CrossFit training would improve sport performance and body composition in young healthy adults.University of Wisconsin--Eau Claire Office of Research and Sponsored Programs

Riding into Health: A Case Study on an Equine-Assisted Childhood Obesity Intervention

In this article, we present an exploratory case study that describes the initial outcomes of the Equine-Assisted Positively Fit (EAPF) program. Children with obesity and their caregivers were recruited to participate in the eight-session program. Results indicated that treatment completers (n = 2) had a decrease in fat mass and fat mass percentage and an increase in fat-free mass and fat-free mass percentage. Moreover, results from accelerometer measurements of physical activity indicated that participants increased their moderate to vigorous physical activity, as well as reported increased self-efficacy for physical activity. Qualitative data from the post-intervention focus group suggested children perceived the treatment acceptable and enjoyable. Findings from this study provide support for future investigations on the feasibility and potential efficacy of pairing children and their caregivers with horses to accomplish health-related goals

The Step Test Evaluation of Performance on Stairs (STEPS): Validation and reliability in a neurological disorder.

BackgroundIndividuals with neurological disorders often have difficulty negotiating stairs that can lead to injurious falls. Clinicians lack a clinical tool to identify impairments in stair negotiation and to assist their decision making regarding treatment plans to improve stair performance and safety. We developed a new tool called the Step Test Evaluation of Performance on Stairs (STEPS) that is designed to assess stair performance and safety in neurological populations.ObjectivesThis study aimed to determine interrater and intrarater reliability of STEPS and its concurrent content validity to various clinical balance and mobility measures using individuals with Huntington's disease (HD) as the first test population.MethodsForty individuals with HD (mean age 50.35) participated. Three observers rated live performances of the STEPS (interrater reliability) and seven observers rated videotaped performances twice (intrarater reliability). STEPS scores correlated with clinical mobility and balance test scores.ResultsExcellent inter- and intrarater reliability (ICCs = 0.91 and 0.89 respectively) and good internal consistency (α = 0.83) were found. Better STEPS performance correlated with better performance on co-administered motor and mobility measures and Stair Self-Efficacy scores. Per multivariable regression analysis, the Unified Huntington's Disease Rating Scale modified motor score and descent time were significant predictors of STEPS performance.ConclusionsThe STEPS tool is easy to administer, requires no special devices and can be completed in less than five minutes. In the HD test population, it shows high reliability and validity making it a potentially useful tool for assessing maneuverability and safety on stairs in HD. The results suggest that the STEPS tool warrants further study to determine STEPS cut-off values for fall prediction in HD and may prove useful as an assessment tool for other neurological disorders
