Molecular characterization of a novel geranylgeranyl pyrophosphate synthase from Plasmodium parasites.

We present here a study of a eukaryotic trans-prenylsynthase from the malaria pathogen Plasmodium vivax. Based on the results of biochemical assays and contrary to previous indications, this enzyme catalyzes the production of geranylgeranyl pyrophosphate (GGPP) rather than farnesyl pyrophosphate (FPP). Structural analysis shows that the product length is constrained by a hydrophobic cavity formed primarily by a set of residues from the same subunit as the product as well as at least one other from the dimeric partner. Furthermore, Plasmodium GGPP synthase (GGPPS) can bind nitrogen-containing bisphosphonates (N-BPs) strongly with the energetically favorable cooperation of three Mg(2+), resulting in inhibition by this class of compounds at IC(50) concentrations below 100 nM. In contrast, human and yeast GGPPSs do not accommodate a third magnesium atom in the same manner, resulting in their insusceptibility to N-BPs. This differentiation is in part attributable to a deviation in a conserved motif known as the second aspartate-rich motif: whereas the aspartates at the start and end of the five-residue motif in FFPP synthases and P. vivax GGPPSs both participate in the coordination of the third Mg(2+), an asparagine is featured as the last residue in human and yeast GGPPSs, resulting in a different manner of interaction with nitrogen-containing ligands.

Crystal structures from the Plasmodium peroxiredoxins: new insights into oligomerization and product binding.

BACKGROUND: Plasmodium falciparum is the protozoan parasite primarily responsible for more than one million malarial deaths, annually, and is developing resistance to current therapies. Throughout its lifespan, the parasite is subjected to oxidative attack, so Plasmodium antioxidant defences are essential for its survival and are targets for disease control. RESULTS: To further understand the molecular aspects of the Plasmodium redox system, we solved 4 structures of Plasmodium peroxiredoxins (Prx). Our study has confirmed PvTrx-Px1 to be a hydrogen peroxide (H2O2)-sensitive peroxiredoxin. We have identified and characterized the novel toroid octameric oligomer of PyTrx-Px1, which may be attributed to the interplay of several factors including: (1) the orientation of the conserved surface/buried arginine of the NNLA(I/L)GRS-loop; and (2) the C-terminal tail positioning (also associated with the aforementioned conserved loop) which facilitates the intermolecular hydrogen bond between dimers (in an A-C fashion). In addition, a notable feature of the disulfide bonds in some of the Prx crystal structures is discussed. Finally, insight into the latter stages of the peroxiredoxin reaction coordinate is gained. Our structure of PyPrx6 is not only in the sulfinic acid (RSO2H) form, but it is also with glycerol bound in a way (not previously observed) indicative of product binding. CONCLUSIONS: The structural characterization of Plasmodium peroxiredoxins provided herein provides insight into their oligomerization and product binding which may facilitate the targeting of these antioxidant defences. Although the structural basis for the octameric oligomerization is further understood, the results yield more questions about the biological implications of the peroxiredoxin oligomerization, as multiple toroid configurations are now known. The crystal structure depicting the product bound active site gives insight into the overoxidation of the active site and allows further characterization of the leaving group chemistry.

Diversity in National Society Leadership and Podium Speakers in Cardiothoracic Surgery.

BACKGROUND: Women and people of color are often underrepresented in medicine. This study examined the inclusivity and diversity of the recent history of the Canadian Association of Thoracic Surgeons (CATS) in both its executive committees and invited participation at its annual meeting. METHODS: CATS internal records and previous programs of CATS annual meetings were reviewed from 1997 to 2020. Leadership positions, invited speakers, and award recipients were categorized by sex and race. RESULTS: Of 199 CATS members in 2020, 93 (47%) were White men, 64 (32%) were men of color, 24 (12%) were White women, and 18 (9%) were women of color. The majority of CATS presidents (86%), committee chairs (57%), named lecturers (88%), other invited speakers (67%), and major award winners (90%) were White men. Women and people of color were underrepresented. The Resident Research Award was the most diverse: of 23 awards, 10 (44%) have been to men of color, 6 (26%) to White men, 4 (15%) to women of color, and 2 (8%) to White women. CONCLUSIONS: There is a need for more representation and inclusion of both women and people of color at multiple levels in CATS. This includes opportunities for improvement in the make-up of its executive committees, the speakers at its annual conference, and the recipients of its awards. CATS has established an Equity, Diversity and Inclusion Task Force to address this critical issue.

Structure and function of a G-actin sequestering protein with a vital role in malaria oocyst development inside the mosquito vector.

Cyclase-associated proteins (CAPs) are evolutionary conserved G-actin-binding proteins that regulate microfilament turnover. CAPs have a modular structure consisting of an N-terminal adenylate cyclase binding domain, a central proline-rich segment, and a C-terminal actin binding domain. Protozoan parasites of the phylum Apicomplexa, such as Cryptosporidium and the malaria parasite Plasmodium, express small CAP orthologs with homology to the C-terminal actin binding domain (C-CAP). Here, we demonstrate by reverse genetics that C-CAP is dispensable for the pathogenic Plasmodium blood stages. However, c-cap(-) parasites display a complete defect in oocyst development in the insect vector. By trans-species complementation we show that the Cryptosporidium parvum ortholog complements the Plasmodium gene functions. Purified recombinant C. parvum C-CAP protein binds actin monomers and prevents actin polymerization. The crystal structure of C. parvum C-CAP shows two monomers with a right-handed beta-helical fold intercalated at their C termini to form the putative physiological dimer. Our results reveal a specific vital role for an apicomplexan G-actin-binding protein during sporogony, the parasite replication phase that precedes formation of malaria transmission stages. This study also exemplifies how Plasmodium reverse genetics combined with biochemical and structural analyses of orthologous proteins can offer a fast track toward systematic gene characterization in apicomplexan parasites.

Structures of parasitic CDPK domains point to a common mechanism of activation.

We recently determined the first structures of inactivated and calcium-activated calcium-dependent protein kinases (CDPKs) from Apicomplexa. Calcium binding triggered a large conformational change that constituted a new mechanism in calcium signaling and a novel EF-hand fold (CAD, for CDPK activation domain). Thus we set out to determine if this mechanism was universal to all CDPKs. We solved additional CDPK structures, including one from the species Plasmodium. We highlight the similarities in sequence and structure across apicomplexan and plant CDPKs, and strengthen our observations that this novel mechanism could be universal to canonical CDPKs. Our new structures demonstrate more detailed steps in the mechanism of calcium activation and possible key players in regulation. Residues involved in making the largest conformational change are the most conserved across Apicomplexa, leading us to propose that the mechanism is indeed conserved. CpCDPK3_CAD and PfCDPK_CAD were captured at a possible intermediate conformation, lending insight into the order of activation steps. PfCDPK3_CAD adopts an activated fold, despite having an inactive EF-hand sequence in the N-terminal lobe. We propose that for most apicomplexan CDPKs, the mode of activation will be similar to that seen in our structures, while specific regulation of the inactive and active forms will require further investigation.

The Cryptosporidium parvum kinome.

BACKGROUND: Hundreds of millions of people are infected with cryptosporidiosis annually, with immunocompromised individuals suffering debilitating symptoms and children in socioeconomically challenged regions at risk of repeated infections. There is currently no effective drug available. In order to facilitate the pursuit of anti-cryptosporidiosis targets and compounds, our study spans the classification of the Cryptosporidium parvum kinome and the structural and biochemical characterization of representatives from the CDPK family and a MAP kinase. RESULTS: The C. parvum kinome comprises over 70 members, some of which may be promising drug targets. These C. parvum protein kinases include members in the AGC, Atypical, CaMK, CK1, CMGC, and TKL groups; however, almost 35% could only be classified as OPK (other protein kinases). In addition, about 25% of the kinases identified did not have any known orthologues outside of Cryptosporidium spp. Comparison of specific kinases with their Plasmodium falciparum and Toxoplasma gondii orthologues revealed some distinct characteristics within the C. parvum kinome, including potential targets and opportunities for drug design. Structural and biochemical analysis of 4 representatives of the CaMK group and a MAP kinase confirms features that may be exploited in inhibitor design. Indeed, screening CpCDPK1 against a library of kinase inhibitors yielded a set of the pyrazolopyrimidine derivatives (PP1-derivatives) with IC50 values of < 10 nM. The binding of a PP1-derivative is further described by an inhibitor-bound crystal structure of CpCDPK1. In addition, structural analysis of CpCDPK4 identified an unprecedented Zn-finger within the CDPK kinase domain that may have implications for its regulation. CONCLUSIONS: Identification and comparison of the C. parvum protein kinases against other parasitic kinases shows how orthologue- and family-based research can be used to facilitate characterization of promising drug targets and the search for new drugs.

An environmental scan of emergency medicine research support, training, and infrastructure across Canada.

OBJECTIVE: Our study objective was to describe the Canadian emergency medicine (EM) research community landscape prior to the initiation of a nationwide network. METHODS: A two-phase electronic survey was sent to 17 Canadian medical schools. The Phase 1 Environmental Scan was administered to department chairs/hospital EM chiefs, to identify EM physicians conducting clinical or educational research. The Phase 2 Survey was sent to the identified EM researchers to assess four themes: 1) geographic distribution, 2) training/career satisfaction, 3) time/financial compensation, and 4) research facilitators/barriers. Descriptive analyses were conducted, and results were stratified by Canadian regions. RESULTS: A total of 92 EM researchers were identified in Phase 1; 67 (73%) responded to the Phase 2 Survey. Of those, 42 (63%) reported being clinical researchers, and 19 (45%) had a graduate degree. Three provinces encompassed most of the researchers (n = 35). Of the respondents, 61% had a research degree, 66% felt adequately trained for their research career, 73% had financial support, 83% had access to office spaces, 52% had no mentor during their first years of their career, 69% felt satisfied with their research career, and 82% suggested that they will still be conducting research in 5 years. CONCLUSION: EM researchers reported being adequately trained, even though only a little over half had a graduate degree. Only two-thirds had financial support, and mentorship was lacking in one-third of the participants. Not all respondents had a form of infrastructure, but most felt optimistic about their careers. The Canadian EM research environment could be improved to ensure better research capacity.

An environmental scan of academic pediatric emergency medicine at Canadian medical schools: Identifying variability across Canada.

OBJECTIVE: To complement our environmental scan of academic emergency medicine departments, we conducted a similar environmental scan of the academic pediatric emergency medicine programs offered by the Canadian medical schools. METHODS: We developed an 88-question form, which was distributed to pediatric academic leaders at each medical school. The responses were validated via email to ensure that the questions were answered completely and consistently. RESULTS: Fourteen of the 17 Canadian medical schools have some type of pediatric emergency medicine academic program. None of the pediatric emergency medicine units have full departmental status, while nine are divisions, two are sections, and three have no status. Canadian academic pediatric emergency medicine is practised at 13 major teaching hospitals and one specialized pediatric emergency department. There are 394 pediatric emergency medicine faculty members, including 13 full professors and 64 associate professors. Eight sites regularly take pediatric undergraduate clinical clerks, and all 14 provide resident education. Fellowship training is offered at 10 sites, with five offering advanced pediatric emergency medicine fellowship training. Half of the sites have at least one physician with a Master's degree in education, totalling 18 faculty members across Canada. There are 31 clinical researchers with salary support at nine universities. Eleven sites have published peer-reviewed papers (n=423) in the past five years, ranging from two to 102 per site. Annual academic budgets range from $10,000 to $2,607,515. CONCLUSIONS: This comprehensive review of academic activities in pediatric emergency medicine across Canada identifies the variability across the country, including the recognition of sites above and below the national average, which may prompt change at individual sites. Sharing these academic practices may inspire sites to provide more support to teachers, educators, and researchers.

Genome-scale protein expression and structural biology of Plasmodium falciparum and related Apicomplexan organisms.

Parasites from the protozoan phylum Apicomplexa are responsible for diseases, such as malaria, toxoplasmosis and cryptosporidiosis, all of which have significantly higher rates of mortality and morbidity in economically underdeveloped regions of the world. Advances in vaccine development and drug discovery are urgently needed to control these diseases and can be facilitated by production of purified recombinant proteins from Apicomplexan genomes and determination of their 3D structures. To date, both heterologous expression and crystallization of Apicomplexan proteins have seen only limited success. In an effort to explore the effectiveness of producing and crystallizing proteins on a genome-scale using a standardized methodology, over 400 distinct Plasmodium falciparum target genes were chosen representing different cellular classes, along with select orthologues from four other Plasmodium species as well as Cryptosporidium parvum and Toxoplasma gondii. From a total of 1008 genes from the seven genomes, 304 (30.2%) produced purified soluble proteins and 97 (9.6%) crystallized, culminating in 36 crystal structures. These results demonstrate that, contrary to previous findings, a standardized platform using Escherichia coli can be effective for genome-scale production and crystallography of Apicomplexan proteins. Predictably, orthologous proteins from different Apicomplexan genomes behaved differently in expression, purification and crystallization, although the overall success rates of Plasmodium orthologues do not differ significantly. Their differences were effectively exploited to elevate the overall productivity to levels comparable to the most successful ongoing structural genomics projects: 229 of the 468 target genes produced purified soluble protein from one or more organisms, with 80 and 32 of the purified targets, respectively, leading to crystals and ultimately structures from one or more orthologues.

CAEP 2016 Academic Symposium on Education Scholarship: Training our Future Clinician Educators in Emergency Medicine.

OBJECTIVE: To develop consensus recommendations for training future clinician educators (CEs) in emergency medicine (EM). METHODS: A panel of EM education leaders was assembled from across Canada and met regularly by teleconference over the course of 1 year. Recommendations for CE training were drafted based on the panel's experience, a literature review, and a survey of current and past EM education leaders in Canada. Feedback was sought from attendees at the Canadian Association of Emergency Physicians (CAEP) annual academic symposium. Recommendations were distributed to the society's Academic Section for further feedback and updated by a consensus of the expert panel. RESULTS: Recommendations were categorized for one of three audiences: 1) Future CEs; 2) Academic departments and divisions (AD&D) that support training to fulfill their education leadership goals; and 3) The CAEP Academic Section. Advanced medical education training is recommended for any emergency physician or resident who pursues an education leadership role. Individuals should seek out mentorship in making decisions about career opportunities and training options. AD&D should regularly perform a needs assessment of their future CE needs and identify and encourage potential individuals who fulfill education leadership roles. AD&D should develop training opportunities at their institution, provide support to complete this training, and advocate for the recognition of education scholarship in their institutional promotions process. The CAEP Academic Section should support mentorship of future CEs on a national scale. CONCLUSION: These recommendations serve as a framework for training and supporting the next generation of Canadian EM medical educators.

An Environmental Scan of Academic Emergency Medicine at the 17 Canadian Medical Schools: Why Does this Matter to Emergency Physicians?

OBJECTIVE: We sought to conduct a major objective of the CAEP Academic Section, an environmental scan of the academic emergency medicine programs across the 17 Canadian medical schools. METHODS: We developed an 84-question questionnaire, which was distributed to academic heads. The responses were validated by phone by the lead author to ensure that the questions were answered completely and consistently. Details of pediatric emergency medicine units were excluded from the scan. RESULTS: At eight of 17 universities, emergency medicine has full departmental status and at two it has no official academic status. Canadian academic emergency medicine is practiced at 46 major teaching hospitals and 13 specialized pediatric hospitals. Another 69 Canadian hospital EDs regularly take clinical clerks and emergency medicine residents. There are 31 full professors of emergency medicine in Canada. Teaching programs are strong with clerkships offered at 16/17 universities, CCFP(EM) programs at 17/17, and RCPSC residency programs at 14/17. Fourteen sites have at least one physician with a Master's degree in education. There are 55 clinical researchers with salary support at 13 universities. Sixteen sites have published peer-reviewed papers in the past five years, ranging from four to 235 per site. Annual budgets range from $200,000 to $5,900,000. CONCLUSION: This comprehensive review of academic activities in emergency medicine across Canada identifies areas of strengths as well as opportunities for improvement. CAEP and the Academic Section hope we can ultimately improve ED patient care by sharing best academic practices and becoming better teachers, educators, and researchers.

CAEP 2015 Academic Symposium: Recommendations for University Governance and Administration for Emergency Medicine.

OBJECTIVE: 1) To identify the strengths and challenges of governance structures in academic emergency medicine (EM), and 2) to make recommendations on principles and approaches that may guide improvements. METHODS: Over the course of 9 months, eight established EM leaders met by teleconference, reviewed the literature, and discussed their findings and experiences to arrive at recommendations on governance in academic units of EM. The results and recommendations were presented at the annual Canadian Association of Emergency Physicians (CAEP) Academic Symposium, where attendees provided feedback. The updated recommendations were subsequently distributed to the CAEP Academic Section for further input, and the final recommendations were decided by consensus. RESULTS: The panel identified four governance areas of interest: 1) the elements of governance; 2) the relationships between emergency physicians and academic units of EM, and between the academic units of EM and faculty of medicine; 3) current status of governance in Canadian academic units of EM; and 4) essential elements of good governance. Six recommendations were developed around three themes, including 1) the importance of good governance; 2) the purposes of an academic unit of EM; and 3) essential elements for better governance for academic units of EM. Recommendations included identifying the importance of good governance, recognizing the need to adapt to the different models depending on the local environment; seeking full departmental status, provided it is mutually beneficial to EM and the faculty of medicine (and health authority); using a consultation service to learn from the experience of other academic units of EM; and establishing an annual forum for EM leaders. CONCLUSION: Although governance of academic EM is complex, there are ways to iteratively improve the mission of academic units of EM: providing exceptional patient care through research and education. Although there is no one-size-fits-all guide, there are practical recommended steps for academic units of EM to consider.

CAEP 2015 Academic Symposium: Current State and Recommendations to Achieve Adequate and Sustainable Funding for Emergency Medicine Academic Units.

OBJECTIVES: To describe the current state of academic emergency medicine (EM) funding in Canada and develop recommendations to grow and establish sustainable funding. METHODS: A panel of eight leaders from different EM academic units was assembled. Using mixed methods (including a literature review, sharing of professional experiences, a survey of current EM academic heads, and data previously collected from an environmental scan), 10 recommendations were drafted and presented at an academic symposium. Attendee feedback was incorporated, and the second set of draft recommendations was further distributed to the Canadian Association Emergency Physicians (CAEP) Academic Section for additional comments before being finalized. RESULTS: Recommendations were developed around the funding challenges identified and solutions developed by academic EM university-based units across Canada. A strategic plan was seen as integral to achieving strong funding of an EM unit, especially when it aligned with departmental and institutional priorities. A business plan, although occasionally overlooked, was deemed an important component for planning and sustaining the academic mission. A number of recommendations surrounding philanthropy consisted of creating partnerships with existing foundations and engaging multiple stakeholders and communities. Synergy between academic and clinical EM departments was also viewed as an opportunity to ensure integration of common missions. Education and networking for current and future leaders were also viewed as invaluable to ensure that opportunities are optimized through strong leadership development and shared experiences to further the EM academic missions across the country. CONCLUSIONS: These recommendations were designed to improve the financial circumstances for many Canadian EM units. There is a considerable wealth of resources that can contribute to financial stability for an academic unit, and an annual networking meeting and continuing education on these issues will facilitate more rapid implementation of these recommendations.

CAEP 2015 Academic Symposium: Leadership within the emergency medicine academic community and beyond.

OBJECTIVES: A panel of emergency medicine (EM) leaders endeavoured to define the key elements of leadership and its models, as well as to formulate consensus recommendations to build and strengthen academic leadership in the Canadian EM community in the areas of mentorship, education, and resources. METHODS: The expert panel comprised EM leaders from across Canada and met regularly by teleconference over the course of 9 months. From the breadth of backgrounds and experience, as well as a literature review and the development of a leadership video series, broad themes for recommendations around the building and strengthening of EM leadership were presented at the CAEP 2015 Academic Symposium held in Edmonton, Alberta. Feedback from the attendees (about 80 emergency physicians interested in leadership) was sought. Subsequently, draft recommendations were developed by the panel through attendee feedback, further review of the leadership video series, and expert opinion. The recommendations were distributed to the CAEP Academic Section for further feedback and updated by consensus of the expert panel. RESULTS: The methods informed the panel who framed recommendations around four themes: 1) leadership preparation and training, 2) self-reflection/emotional intelligence, 3) academic leadership skills, and 4) gender balance in academic EM leadership. The recommendations aimed to support and nurture the next generation of academic EM leaders in Canada and included leadership mentors, availability of formal educational courses/programs in leadership, self-directed education of aspiring leaders, creation of a Canadian subgroup with the AACEM/SAEM Chair Development Program, and gender balance in leadership roles. CONCLUSIONS: These recommendations serve as a roadmap for all EM leaders (and aspiring leaders) to build on their success, inspire their colleagues, and foster the next generation of Canadian EM academic leaders.

Executive summary of the CAEP 2014 Academic Symposium: How to make research succeed in your department.

The vision of the recently created Canadian Association of Emergency Physicians (CAEP) Academic Section is to promote high-quality emergency patient care by conducting world-leading education and research in emergency medicine. The Academic Section plans to achieve this goal by enhancing academic emergency medicine primarily at Canadian medical schools and teaching hospitals. It seeks to foster and develop education, research, and academic leadership amongst Canadian emergency physicians, residents, and students. In this light, the Academic Section began in 2013 to hold the annual Academic Symposia to highlight best practices and recommendations for the three core domains of governance and leadership, education scholarship, and research. Each year, members of three panels are asked to review the literature, survey and interview experts, achieve consensus, and present their recommendations at the Symposium (2013, Education Scholarship; 2014, Research; and 2015, Governance and Funding). Research is essential to medical advancement. As a relatively young specialty, emergency medicine is rapidly evolving to adapt to new diagnostic tools, the challenges of crowding in emergency departments, and the growing needs of emergency patients. There is significant variability in the infrastructure, support, and productivity of emergency medicine research programs across Canada. All Canadians benefit from an investigation of the means to improve research infrastructure, training programs, and funding opportunities. Such an analysis is essential to identify areas for improvement, which will support the expansion of emergency medicine research. To this end, physician-scientist leaders were gathered from across Canada to develop pragmatic recommendations on the improvement of emergency medicine research through a comprehensive analysis of current best practices, systematic literature reviews, stakeholder surveys, and expert interviews.

CAEP 2014 Academic symposium: "How to make research succeed in your department: How to fund your research program".

OBJECTIVE: We sought to gather a comprehensive list of funding strategies and opportunities for emergency medicine (EM) centres across Canada, and make recommendations on how to successfully fund all levels of research activity, including research projects, staff salaries, infrastructure, and researcher stipends. METHODS: We formed an expert panel consisting of volunteers recognized nationally for their scholarly work in EM. First, we conducted interviews with academic leaders and researchers to obtain a description of their local funding strategies using a standardized open-ended questionnaire. Panelists then identified emerging funding models. Second, we listed funding opportunities and initiatives at the provincial, national, and international levels. Finally, we used an iterative consensus-based approach to derive pragmatic recommendations after incorporating comments and suggestions from participants at an academic symposium. RESULTS: Our review of funding strategies identified four funding models: 1) investigator dependent model, 2) practice plan, 3) generous benefactor, and 4) mixed funding. Recommendations in this document include approaches for research contributors and producers (seven recommendations), for local academic leaders (five recommendations), and for national organizations, such as the Canadian Association of Emergency Physicians (CAEP) (three recommendations). CONCLUSIONS: Funding for research in EM varies across Canada and is largely insecure. We offer recommendations to help facilitate funding for large and small projects, for salary support, and for local and national leaders to advance EM research. We believe that these recommendations will increase funding for all levels of EM research activity, including research projects, staff salaries, infrastructure, and researcher stipends.

CAEP 2014 Academic Symposium: "How to make research succeed in your department: Promoting excellence in Canadian emergency medicine resident research".

OBJECTIVES: To characterize the current state of Canadian emergency medicine (EM) resident research and develop recommendations to promote excellence in this area. METHODS: We performed a systematic review of MEDLINE, Embase, and ERIC using search terms relevant to EM resident research. We conducted an online survey of EM residency program directors from the Royal College of Physicians and Surgeons of Canada (RCPSC) and College of Family Physicians of Canada (CFPC). An expert panel reviewed these data, presented recommendations at the Canadian Association of Emergency Physicians 2014 Academic Symposium, and refined them based on feedback received. RESULTS: Of 654 potentially relevant citations, 35 articles were included. These were categorized into four themes: 1) expectations and requirements, 2) training and assessment, 3) infrastructure and support, and 4) dissemination. We received 31 responses from all 31 RCPSC-EM and CFPC-EM programs. The majority of EM programs reported requiring a resident scholarly project; however, we found wide-ranging expectations for the type of resident research performed and how results were disseminated, as well as the degree of completion expected. Although 93% of RCPSC-EM programs reported providing formal training on how to conduct research, only 53% of CFPC-EM programs reported doing so. Almost all programs (94%) reported having infrastructure in place to support resident research, but the nature of support was highly variable. Finally, there was marked variability regarding the number of resident-published abstracts and manuscripts. CONCLUSIONS: Based on the literature, our national survey, and discussions with stakeholders, we offer 14 recommendations encompassing goals, expectations, training, assessment, infrastructure, and dissemination in order to improve Canadian EM resident research.

CAEP 2014 Academic Symposium: "How to make research succeed in your emergency department: How to develop and train career researchers in emergency medicine".

OBJECTIVES: We sought to 1) identify best practices for training and mentoring clinician researchers, 2) characterize facilitators and barriers for Canadian emergency medicine researchers, and 3) develop pragmatic recommendations to improve and standardize emergency medicine postgraduate research training programs to build research capacity. METHODS: We performed a systematic review of MEDLINE and Embase using search terms relevant to emergency medicine research fellowship/graduate training. We conducted an email survey of all Canadian emergency physician researchers. The Society for Academic Emergency Medicine (SAEM) research fellowship program was analysed, and other similar international programs were sought. An expert panel reviewed these data and presented recommendations at the Canadian Association of Emergency Physicians (CAEP) 2014 Academic Symposium. We refined our recommendations based on feedback received. RESULTS: Of 1,246 potentially relevant citations, we included 10 articles. We identified five key themes: 1) creating training opportunities; 2) ensuring adequate protected time; 3) salary support; 4) infrastructure; and 5) mentorship. Our survey achieved a 72% (67/93) response rate. From these responses, 42 (63%) consider themselves clinical researchers (i.e., spend a significant proportion of their career conducting research). The single largest constraint to conducting research was funding. Factors felt to be positive contributors to a clinical research career included salary support, research training (including an advanced graduate degree), mentorship, and infrastructure. The SAEM research fellowship was the only emergency medicine research fellowship program identified. This 2-year program requires approval of both the teaching centre and each applying fellow. This program requires training in 15 core competencies, manuscript preparation, and submission of a large grant to a national peer-review funding organization. CONCLUSIONS: We recommend that the CAEP Academic Section create a process to endorse research fellowship/graduate training programs. These programs should include two phases: Phase I: Research fellowship/graduate training would include an advanced research university degree and 15 core learning areas. Phase II: research consolidation involves a further 1-3 years with an emphasis on mentorship and scholarship production. It is anticipated that clinician scientists completing Phase I and Phase II training at a CAEP Academic Section-endorsed site(s) will be independent researchers with a higher likelihood of securing external peer-reviewed funding and be able to have a meaningful external impact in emergency medicine research.
