RESUMO

PURPOSE: Studies have demonstrated poor mental health in medical students. However, there is wide variation in study design and metric use, impairing comparability. The authors aimed to examine the metrics and methods used to measure medical student wellbeing across multiple timepoints and identify where guidance is necessary. METHODS: Five databases were searched between May and June 2021 for studies using survey-based metrics among medical students at multiple timepoints. Screening and data extraction were done independently by two reviewers. Data regarding the manuscript, methodology, and metrics were analyzed. RESULTS: 221 studies were included, with 109 observational and 112 interventional studies. There were limited studies (15.4%) focused on clinical students. Stress management interventions were the most common (40.2%). Few (3.57%) interventional studies followed participants longer than 12 months, and 38.4% had no control group. There were 140 unique metrics measuring 13 constructs. 52.1% of metrics were used only once. CONCLUSIONS: Unique guidance is needed to address gaps in study design as well as unique challenges surrounding medical student wellbeing surveys. Metric use is highly variable and future research is necessary to identify metrics specifically validated in medical student samples that reflect the diversity of today's students.

RESUMO

BACKGROUND: Avoidable disparities in health outcomes persist in Canada despite substantial investments in a publicly funded health care system that includes preventive services. Our objective was to provide preventive care recommendations that promote health equity by prioritizing effective interventions for people experiencing disadvantages. METHODS: The guideline was developed by a primary care provider-patient panel, with input from a patient-partner panel with diverse lived experiences. After selecting priority topics, we searched for systematic reviews and recent randomized controlled trials of screening and other relevant studies of screening accuracy and management efficacy. We used the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach to develop recommendations and followed the Appraisal of Guidelines for Research and Evaluation (AGREE II) reporting guidance. We managed competing interests using the Guideline International Network principles. The recommendations were externally reviewed by content experts and circulated for endorsement by national stakeholders. RECOMMENDATIONS: We developed 15 screening and other preventive care recommendations and 1 policy recommendation on improving access to primary care. We recommend prioritized outreach for colorectal cancer screening starting at age 45 years and for cardiovascular disease risk assessment, to help address inequities and promote health. Specific interventions that should be rolled out in ways that address inequities include human papillomavirus (HPV) self-testing, HIV self-testing and interferon-γ release assays for tuberculosis infection. Screening for depression, substance use, intimate partner violence and poverty should help connect people experiencing specific disadvantages with proven interventions. We recommend automatic connection to primary care for people experiencing disadvantages. INTERPRETATION: Proven preventive care interventions can address health inequities if people experiencing disadvantages are prioritized. Clinicians, health care organizations and governments should take evidence-based actions and track progress in promoting health equity across Canada.

RESUMO

Objective: There are many challenges in ensuring medical students learn paediatrics. Medical educators must develop and maintain curricula that meet learners' needs and accreditation requirements. Paediatricians and family physicians, practicing and teaching in busy clinical environments, require Canadian-relevant curricular guidance and resources to teach and assess learners. Students struggle with curricular cohesion, clear expectations, and resources. Recognizing these challenges and acknowledging the need to address them, the Paediatric Undergraduate Program Directors of Canada (PUPDOC) created canuc-paeds, a comprehensive competency-based undergraduate curriculum that teachers and students would actually use. Methods: Curriculum development included the following: utilization of best practices in curriculum development, an environmental scan, development of guiding principles, Delphi surveys, in-person meetings, and quality improvement. All Canadian paediatric undergraduate educator leaders and other stakeholders were invited to participate. Results: The curriculum, based on the RCPSC CanMEDS Framework, includes 29 clinical presentations, each with key conditions, foundational knowledge objectives, and learning resources. Essential paediatric-specific physical examination and procedural skills that graduating medical students are expected to perform are identified. Objectives specific to Intrinsic Roles of Collaborator, Communicator, Professional, Leader, Health Advocate and Scholar that can be assessed in the field of paediatrics at the undergraduate level are articulated. The national curriculum has been implemented widely at Canadian medical schools. Online, open-access clinical resources have been developed and are being used world-wide. Conclusion: This curriculum provides overarching Canadian-specific curricular guidance and resources for students and for the paediatricians and family physicians who are responsible for teaching and assessing undergraduate learners.

RESUMO

CONTEXTE: Malgré des investissements importants dans un système de soins de santé public qui comprend des services préventifs, on continue d'observer des disparités évitables en matière de santé au Canada. L'équipe avait pour objectif de formuler des recommandations pour des soins de santé préventifs qui puissent améliorer l'équité en matière de santé par la priorisation des interventions efficaces à l'intention des groupes défavorisés. MÉTHODES: La ligne directrice a été élaborée par un comité composé de spécialistes en soins primaires et de membres de la patientèle, avec la contribution d'un groupe de patientes-et patientspartenaires ayant vécu diverses expériences. Après avoir sélectionné les sujets à prioriser, nous avons recensé les revues systématiques, les essais randomisés et contrôlés récents sur les méthodes de dépistage et d'autres études pertinentes sur l'efficacité du dépistage et de la prise en charge. Nous avons utilisé l'approche GRADE (Grading of Recommendations, Assessment, Development and Evaluation) pour formuler les recommandations et avons suivi le guide AGREE II (Appraisal of Guidelines for Research and Evaluation) pour rédiger le rapport. Il en a été de même avec les principes du Guidelines International Network pour la gestion des intérêts concurrents. Les recommandations ont été passées en revue par un comité externe d'experts en contenu avant d'être distribuées à des intervenants à l'échelle nationale pour approbation. RECOMMANDATIONS: Nous avons formulé 15 recommandations concernant le dépistage et d'autres soins préventifs et 1 recommandation de nature politique visant à améliorer l'accès aux soins primaires. Ainsi, nous recommandons de prioriser une stratégie de communication pour le dépistage du cancer colorectal à partir de l'âge de 45 ans et pour l'évaluation du risque de maladie cardiovasculaire pour lutter contre les iniquités en matière de santé et promouvoir la santé. Les interventions particulières qui devraient être déployées pour lutter contre les iniquités comprennent l'autodépistage du virus du papillome humain (VPH) et du VIH, et le test de libération de l'interféron γ pour l'infection tuberculeuse. Le dépistage de la dépression, de la toxicomanie, de la violence conjugale et de la pauvreté devrait également permettre aux personnes touchées d'accéder plus facilement à des interventions éprouvées. Nous recommandons une prise de contact systématique avec des professionnels de la santé en soins primaires pour les personnes défavorisées. INTERPRÉTATION: Les interventions préventives éprouvées peuvent aider à combattre les iniquités en matière de santé si la priorité est accordée aux personnes défavorisées. Les médecins, les organisations de santé et les gouvernements devraient adopter des mesures fondées sur des données probantes et en faire le suivi s'ils veulent promouvoir l'équité en matière de santé partout au Canada.

RESUMO

Context/Setting: The script theory of diagnostic reasoning proposes that clinicians evaluate cases in the context of an "illness script," iteratively testing internal hypotheses against new information eventually reaching a diagnosis. We present a novel tool for teaching diagnostic reasoning to undergraduate medical students based on an adaptation of script theory. INTERVENTION: We developed a virtual patient case that used clinically authentic audio and video, interactive three-dimensional (3D) body images, and a simulated electronic medical record. Next, we used interactive slide bars to record respondents' likelihood estimates of diagnostic possibilities at various stages of the case. Responses were dynamically compared to data from expert clinicians and peers. Comparative frequency distributions were presented to the learner and final diagnostic likelihood estimates were analyzed. Detailed student feedback was collected. OBSERVATIONS: Over two academic years, 322 students participated. Student diagnostic likelihood estimates were similar year to year, but were consistently different from expert clinician estimates. Student feedback was overwhelmingly positive: students found the case was novel, innovative, clinically authentic, and a valuable learning experience. DISCUSSION: We demonstrate the successful implementation of a novel approach to teaching diagnostic reasoning. Future study may delineate reasoning processes associated with differences between novice and expert responses.

RESUMO

INTRODUCTION: The New South Wales Rural Resident Medical Officer Cadetship Program began in 1988 as a strategy to increase the numbers of junior doctors in rural hospitals. This article outlines the results of an evaluation undertaken in 2014. Specifically, it will look at where former cadets who entered the program between 1989 and 2010 were working in 2014, what training programs they chose and their attitudes toward the program. METHOD: Data were collected using a semi-structured questionnaire sent to all the former cadets who entered the program from 1989 until 2010. This included self-administered questions relating to background (where the majority of the students' primary schooling was undertaken), vocational training, current role, current work location and attitudes towards the cadetship. Responses were received from 142 of the 211 cadets in the study (67%). RESULTS: Of the 142 former cadets who responded to the questionnaire, 90 had completed a vocational training program and were working as fully qualified medical practitioners. A further 44 were trainees, six were non-specialist hospital doctors and two were no longer practising. Overall, the most popular vocational training programs among fully qualified doctors and trainees combined were general practice, anaesthetics/intensive care and emergency medicine. Over half of the cadets included in the analysis (n=74, 53%) were working in rural areas (Australian Standard Geographical Classification Remoteness Areas 2-5) in 2014 and practice location was significantly (p<0.001) influenced by career choice. Of the cadets working in rural locations, the majority (58%) were working as general practitioners while 38% had chosen other specialties and 4% were working as hospital non-specialists. An equal proportion of cadets came from urban and rural backgrounds while a small proportion grew up overseas. The cadets with rural backgrounds were more likely to choose general practice than those from urban backgrounds. A similar analysis of cadets comparing geographic background and practice location showed cadets of rural background were more likely to be working in a rural location than cadets of urban background. CONCLUSIONS: The cadetship is an effective link between medical school and rural practice. The success of the program relies in part on the mentoring, networking and other educational opportunities available to cadets, which serve to foster their interest and provide a structured pathway to long-term rural practice. It has been demonstrated that targeted incentive based scholarship schemes with a return-of-service component can be beneficial, particularly where they include ongoing support and reinforcement throughout the transition from undergraduate to postgraduate training.

RESUMO

Successfully completing the 'Foundations in End of Life/Palliative Care' distance-learning module has had a measurable effect on the knowledge, competence and confidence of community nurses in the principles and practice of palliative and end-of-life care. An appropriate practice-based education module can empower community nursing practice and have a direct impact on improving the patient-carer experience at the end of life. This article provides evidence from the quantitative and qualitative data from pre- and post-module self-assessment questionnaires along with the successful completion of an electronic multiple-choice questionnaire and short-answer classroom test to demonstrate this.

RESUMO

Background The coronavirus disease 2019 (COVID-19) pandemic had a major impact on medical education with clerkship students abruptly removed from clinical activities in 2020 and hastily immersed in online learning to maintain medical education. In 2022, students returned to in-person clinical experiences, but synchronous learning sessions continued online with extensive use of asynchronous online resources. This change offers a unique opportunity to gather information about students' perspectives regarding the acceptability and effectiveness of online learning strategies. This study aims to explore the clerkship student experience with the integration of online learning and in-person learning into formalized educational sessions in clerkship. Methodology The authors administered an online survey to clerkship students at the Cumming School of Medicine at the University of Calgary, Canada in spring 2022. The survey consisted of primarily Likert-style questions to explore the perceived effectiveness of various online learning strategies. Results are reported as the proportion selecting "quite effective" or "extremely effective." Results A total of 89 students responded to the survey (57.4% of graduating class). For synchronous online learning, case-based learning was perceived as the most effective teaching strategy (61.8%), and audience response systems were the most effective strategy for improving audience engagement (70.1%). For asynchronous online learning, interactive cases (84.9%) and student-developed online study guides (83.6%) were perceived as the most effective. Students held varying perceptions regarding how online learning impacted their well-being. When considering future clerkship curricula, the majority of clerkship students preferred a blend of in-person and online learning. Conclusions This study identified that most clerkship students prefer a hybrid of in-person and online learning and that ideal online learning curricula could include case-based learning, audience response systems, and a variety of asynchronous learning resources. These results can guide curriculum development and design at other medical institutions.

RESUMO

Abs have been shown to be protective in passive immunotherapy of tuberculous infection using mouse experimental models. In this study, we report on the properties of a novel human IgA1, constructed using a single-chain variable fragment clone (2E9), selected from an Ab phage library. The purified Ab monomer revealed high binding affinities for the mycobacterial α-crystallin Ag and for the human FcαRI (CD89) IgA receptor. Intranasal inoculations with 2E9IgA1 and recombinant mouse IFN-γ significantly inhibited pulmonary H37Rv infection in mice transgenic for human CD89 but not in CD89-negative littermate controls, suggesting that binding to CD89 was necessary for the IgA-imparted passive protection. 2E9IgA1 added to human whole-blood or monocyte cultures inhibited luciferase-tagged H37Rv infection although not for all tested blood donors. Inhibition by 2E9IgA1 was synergistic with human rIFN-γ in cultures of purified human monocytes but not in whole-blood cultures. The demonstration of the mandatory role of FcαRI (CD89) for human IgA-mediated protection is important for understanding of the mechanisms involved and also for translation of this approach toward development of passive immunotherapy of tuberculosis.

RESUMO

UNLABELLED: An earlier reported laboratory assay, performed in The Netherlands, to diagnose Schistosoma infections by detection of the parasite antigen CAA in serum was converted to a more user-friendly format with dry reagents. The improved assay requires less equipment and allows storage and worldwide shipping at ambient temperature. Evaluation of the new assay format was carried out by local staff at Ampath Laboratories, South Africa. The lateral flow (LF) based assay utilized fluorescent ultrasensitive up-converting phosphor (UCP) reporter particles, to be read by a portable reader (UPlink) that was also provided to the laboratory. Over a period of 18 months, about 2000 clinical samples were analyzed prospectively in parallel with a routinely carried out CAA-ELISA. LF test results and ELISA data correlated very well at CAA concentrations above 300 pg/mL serum. At lower concentrations the UCP-LF test indicates a better performance than the ELISA. The UCP-LF strips can be stored as a permanent record as the UCP label does not fade. At the end of the 18 months testing period, LF strips were shipped back to The Netherlands where scan results obtained in South Africa were validated with different UCP scanning equipment including a novel, custom developed, small lightweight UCP strip reader (UCP-Quant), well suited for testing in low resource settings. CONCLUSION: The dry format UCP-LF assay was shown to provide a robust and easy to use format for rapid testing of CAA antigen in serum. It performed at least as good as the ELISA with respect to sensitivity and specificity, and was found to be superior with respect to speed and simplicity of use. Worldwide shipping at ambient temperature of the assay reagents, and the availability of small scanners to analyze the CAA UCP-LF strip, are two major steps towards point-of-care (POC) applications in remote and resource poor environments to accurately identify low (30 pg CAA/mL serum; equivalent to about 10 worm pairs) to heavy Schistosoma infections.

RESUMO

UNLABELLED: BACKGROUND, AIMS AND METHODS: Recent years have seen the introduction of web-based technologies such as the 'wiki', which is a webpage whose content can be edited in real time using a web browser. This article reviews the current state of knowledge about the use of wikis in education, and considers whether wiki technology has features that might prove useful in medical education. RESULTS: Advantages and challenges of the technology are discussed, and recommendations for use are provided. We believe that wiki technology offers a number of potential benefits for administrators, students and instructors, including the ability to share information online, to construct knowledge together, to facilitate collaboration and to enable social learning and peer feedback. CONCLUSIONS: We believe that with proper planning and instructional design, wiki technology can be usefully employed in medical education. We intend to continue to study the impact of wiki technology in our own programme, and we encourage others to evaluate the application of wiki technology in other areas of medical education.

RESUMO

Medical students enter medical school with similar or even better well-being than their age-matched peers in other educational programs, but there is predictable erosion of their well-being following matriculation. Interventions to counter this erosion predominantly focus on the individual level; however, significant systemic issues persist that thwart meaningful change. Effectively reforming the learning environment and more broadly targeting problematic aspects of the culture of medical education are essential steps to advance efforts to improve medical learner well-being. Although a healthy environment may allow learners to be well in the educational setting, a health-promoting learning environment strives to promote and embed well-being across all aspects of the learner's experience. Health-promoting learning environments operate by infusing health principles into all aspects of operations, practices, mandates, and businesses. The Okanagan Charter is a widely adopted international framework with principles for best practices of adoption. This charter has the recent endorsement of the Association of Faculties of Medicine of Canada, representing all faculties of medicine in Canada, and serves as a framework for reassessing work on well-being in medical education. In response to this endorsement, the authors have adapted the 5 strategies from the charter for pragmatic integration into the medical education environment and added a sixth strategy: (1) embed health in all policies; (2) develop sustainable, supportive spaces; (3) create thriving medical communities and culture; (4) encourage, support, and sustain meaningful personal development; (5) review, develop, and strengthen faculty-level health services; and (6) collaborate and invest in continuous improvement and evaluation. For each of these 6 strategic directions, actionable steps for implementation in academic medicine are provided to create sustainable and meaningful change.

RESUMO

Implication Statement: Enacting change in medical education requires effective facilitation processes. Medical education lags behind other fields in systems innovation and radically disruptive approaches to the challenges we encounter. Design thinking "sprints," widely used in many other settings, serve as an opportunity to fill the gap as a facilitation process during periods requiring extensive and/or rapid change. Though resource-intensive, our experience using design thinking sprints for a situation requiring urgent change management with high-stakes implications for Canadian medical education to demonstrate their utility. A more widespread, adoption can contribute to innovation within all aspects of education including curriculum design, policy development, and educational process renewal. Énoncé des implications de la recherche: La mise en œuvre de changements dans la formation médicale exige un processus de facilitation efficace. Comparée à d'autres disciplines, l'éducation médicale est à la traîne en ce qui concerne l'innovation des systèmes et l'adoption d'approches radicalement transformatrices en réponse aux défis rencontrés. Le sprint de conception creative (design thinking sprints), approche largement utilisée dans de nombreux contextes, pourraient permettre de combler le manque de processus de facilitation lorsque des changements importants ou rapides sont à l'œuvre. Notre expérience de l'utilisation de tels sprints dans une situation nécessitant une gestion urgente de changements à enjeux importants pour l'éducation médicale au Canada démontre son utilité, malgré les ressources considérables qui ont dû être mobilisées. Une adoption plus large de cette approche peut contribuer à l'innovation dans tous les aspects de l'éducation, y compris la conception des programmes d'études, l'élaboration de politiques et le renouvellement des processus éducatifs.

RESUMO

Context: Children with Down syndrome are at risk for obstructive sleep apnea, which may not be resolved by adenotonsillecotmy, as well as other respiratory disorders that may impact breathing during sleep. Long-term non-invasive ventilation, including continuous and bilevel positive airway pressure delivery, is an alternate treatment strategy. Objective: To assess the use and outcomes of long-term non-invasive ventilation in children with Down syndrome including comparison to other children using long-term non-invasive ventilation. Data Sources: The search strategy for the scoping review used Medical Subject Headings (MeSH) and free-text terms for "child" and "non-invasive ventilation." MEDLINE (Ovid), Embase (Ovid), CINAHL (Ebsco), Cochrane Library (Wiley), and PubMed databases were searched (1990-2021). Study Selection: The scoping review results were searched to identify studies including data on at least three children with Down Syndrome using long-term non-invasive ventilation. Data Extraction: Study characteristics, subject characteristics, technology type, and outcome measurements were extracted. Results: A total of 28 articles included 543 children with Down syndrome using long-term non-invasive ventilation. Children with Down syndrome accounted for 18% of children using long-term non-invasive ventilation. Data on efficacy, feasibility, and adherence in children with Down syndrome are comparable to other children. Children with Down syndrome may have greater difficulty initiating long-term non-invasive ventilation, longer time to establish use, and a higher rate of inability to establish use. Outcome data is limited but suggest favorable impact on cardiac function and attention. Limitations: Articles related to long-term non-invasive ventilation use in adolescents and young adults may have been excluded. Conclusions: Children with Down syndrome make up a significant portion of the population of children using long-term non-invasive ventilation. While there is more limited data available with respect to the use and outcomes for children with Down syndrome compared to the other children, long-term non-invasive ventilation is an effective and well-tolerated therapy with no clear differences in the use or outcomes for children with Down syndrome. Additional work is needed to understand potential challenges around establishing long-term non-invasive ventilation use in children with Down syndrome.

RESUMO

Here we unravel the structural features of human IgM and IgA that govern their interaction with the human Fcalpha/mu receptor (hFcalpha/muR). Ligand polymerization status was crucial for the interaction, because hFcalpha/muR binding did not occur with monomeric Ab of either class. hFcalpha/muR bound IgM with an affinity in the nanomolar range, whereas the affinity for dimeric IgA (dIgA) was tenfold lower. Panels of mutant IgM and dIgA were used to identify regions critical for hFcalpha/muR binding. IgM binding required contributions from both Cmu3 and Cmu4 Fc domains, whereas for dIgA, an exposed loop in the Calpha3 domain was crucial. This loop, comprising residues Pro440-Phe443, lies at the Fc domain interface and has been implicated in the binding of host receptors FcalphaRI and polymeric Ig receptor (pIgR), as well as IgA-binding proteins produced by certain pathogenic bacteria. Substitutions within the Pro440-Phe443 loop resulted in loss of hFcalpha/muR binding. Furthermore, secretory component (SC, the extracellular portion of pIgR) and bacterial IgA-binding proteins were shown to inhibit the dIgA-hFcalpha/muR interaction. Therefore, we have identified a motif in the IgA-Fc inter-domain region critical for hFcalpha/muR interaction, and highlighted the multi-functional nature of a key site for protein-protein interaction at the IgA Fc domain interface.

RESUMO

BACKGROUND: Each year thousands of pregnant women experiencing threatened premature labour are transferred considerable distances across Australia to access higher level facilities but only a small proportion of these women go on to actually give birth to a premature baby. Women from regional areas are required to move away from their home, children and support networks because of a perceived risk of birthing in a centre without neonatal intensive care facilities. AIM: This study examines the experience of women undergoing antenatal transfer for threatened premature labour in New South Wales and the Australian Capital Territory who do not give birth during their transfer admission. METHODS: Thirteen semi-structured in-depth interviews were held with women across five tertiary referral sites across New South Wales and the Australian Capital Territory, and analysed until saturation for themes. FINDINGS: Seven urban and six rural women were interviewed. Women and their families were all negatively affected by antenatal transfer. Factors that helped enable a positive experience were; enhanced sense of safety in the tertiary unit, and individual qualities of staff. Factors that contributed to negative experiences were; inadequate and conflicting information, and no involvement or choice in the clinical decision-making process to move to another facility. CONCLUSIONS: Antenatal transfer is an extremely stressful experience for women and their families. The provision of high quality written and verbal information, and the inclusion of women's perception of risk in the clinical decision making process will improve the experience for women and their families in NSW and the ACT.

RESUMO

Recombinant versions of the seven equine IgG subclasses were expressed in CHO cells. All assembled into intact immunoglobulins stabilised by disulphide bridges, although, reminiscent of human IgG4, a small proportion of equine IgG4 and IgG7 were held together by non-covalent bonds alone. All seven IgGs were N-glycosylated. In addition IgG3 appeared to be O-glycosylated and could bind the lectin jacalin. Staphylococcal protein A displayed weak binding for the equine IgGs in the order: IgG1>IgG3>IgG4>IgG7>IgG2=IgG5>IgG6. Streptococcal protein G bound strongly to IgG1, IgG4 and IgG7, moderately to IgG3, weakly to IgG2 and IgG6, and not at all to IgG5. Analysis of antibody effector functions revealed that IgG1, IgG3, IgG4, IgG5 and IgG7, but not IgG2 and IgG6, were able to elicit a strong respiratory burst from equine peripheral blood leukocytes, predicting that the former five IgG subclasses are able to interact with Fc receptors on effector cells. IgG1, IgG3, IgG4 and IgG7, but not IgG2, IgG5 and IgG6, were able to bind complement C1q and activate complement via the classical pathway. The differential effector function capabilities of the subclasses suggest that, for maximum efficacy, equine vaccine strategies should seek to elicit antibody responses of the IgG1, IgG3, IgG4, and IgG7 subclasses.

RESUMO

In order to build on and improve the palliative care knowledge and skills of the district nurses in Cardiff, and the Vale of Glamorgan, the South East Wales Cancer Network in partnership with the local NHS Trust, commissioned Cardiff University to develop, implement and audit a bespoke distance learning style module in the foundations of end of life and palliative care. This will be utilised as an internal requirement for all band 5 and 6 nurses. The outcomes will determine whether the module is suitable as an All-Wales programme and whether it has potential for use with other disciplines.
