Assessment of Emergency Medicine Resident Performance in a Pediatric In Situ Simulation Using Multi-Source Feedback.

Introduction Multi-source feedback (MSF) is an evaluation method mandated by the Accreditation Council for Graduate Medical Education (ACGME). The Queen's Simulation Assessment Tool (QSAT) has been validated as being able to distinguish between resident performances in a simulation setting. The QSAT has also been demonstrated to have excellent MSF agreement when used in an adult simulation performed in a simulation lab. Using the QSAT, this study sought to determine the degree of agreement of MSF in a single pediatric (Peds) simulation case conducted in situ in a Peds emergency department (ED). Methods This Institutional Review Board-approved study was conducted in a four-year emergency medicine residency. A Peds resuscitation case was developed with specific behavioral anchors on the QSAT, which uses a 1-5 scale in each of five categories: Primary Assessment, Diagnostic Actions, Therapeutic Actions, Communication, and Overall Assessment. Data was gathered from six participants for each simulation. The lead resident self-evaluated and received MSF from a junior peer resident, a fixed Peds ED nurse, a random ED nurse, and two faculty (one fixed, the other from a dyad). The agreement was calculated with intraclass correlation coefficients (ICC). Results The simulation was performed on 35 separate days over two academic years. A total of 106 MSF participants were enrolled. Enrollees included three faculty members, 35 team leaders, 34 peers, 33 ED registered nurses (RN), and one Peds RN; 50% of the enrollees were female (n=53). Mean QSAT scores ranged from 20.7 to 23.4. A fair agreement was demonstrated via ICC; there was no statistically significant difference between sources of MSF. Removing self-evaluation led to the highest ICC. ICC for any single or grouped non-faculty source of MSF was poor. Conclusion Using the QSAT, the findings from this single-site cohort suggest that faculty must be included in MSF. Self-evaluation appears to be of limited value in MSF with the QSAT. The degree of MSF agreement as gathered by the QSAT was lower in this cohort than previously reported for adult simulation cases performed in the simulation lab. This may be due to either the pediatric nature of the case, the location of the simulation, or both.

Designing Higher Resolution Self-Assembled 3D DNA Crystals via Strand Terminus Modifications.

DNA tensegrity triangles self-assemble into rhombohedral three-dimensional crystals via sticky ended cohesion. Crystals containing two-nucleotide (nt) sticky ends (GA:TC) have been reported previously, and those crystals diffracted to 4.9 Å at beamline NSLS-I-X25. Here, we analyze the effect of varying sticky end lengths and sequences as well as the impact of 5'- and 3'-phosphates on crystal formation and resolution. Tensegrity triangle motifs having 1-, 2-, 3-, and 4-nt sticky ends all form crystals. X-ray diffraction data from the same beamline reveal that the crystal resolution for a 1-nt sticky end (G:C) and a 3-nt sticky end (GAT:ATC) were 3.4 and 4.2 Å, respectively. Resolutions were determined from complete data sets in each case. We also conducted trials that examined every possible combination of 1-nucleotide and 2-nucleotide sticky-ended phosphorylated strands and successfully crystallized all 16 possible combinations of strands. We observed the position of the 5'-phosphate on either the crossover (1), helical (2), or central strand (3) affected the resolution of the self-assembled crystals for the 2-turn monomer (3.0 Å for 1-2P-3P) and 2-turn dimer sticky ended (4.1 Å for 1-2-3P) systems. We have also examined the impact of the identity of the base flanking the sticky ends as well as the use of 3'-phosphate. We conclude that crystal resolution is not a simple consequence of the thermodynamics of the direct nucleotide pairing interactions involved in molecular cohesion in this system.

Enhancing access to care in northern rural communities via telehealth.

The cost of providing health care in northern Canada is higher than the rest of Canada. Telehealth has the potential to reduce health care expenditures. Yet this is still underutilised in Canada and globally. This paper describes the services provided through telehealth in some northern regions of Canada. It provides recommendations on the requirements for setting up real presence telehealth and how utilisation can be enhanced. Telehealth offers potential benefits for health outcomes by increasing access to healthcare, and reducing expenditures.

Assessment of Emergency Medicine Resident Performance in an Adult Simulation Using a Multisource Feedback Approach.

INTRODUCTION: The Accreditation Council for Graduate Medical Education (ACGME) specifically notes multisource feedback (MSF) as a recommended means of resident assessment in the emergency medicine (EM) Milestones. High-fidelity simulation is an environment wherein residents can receive MSF from various types of healthcare professionals. Previously, the Queen's Simulation Assessment Tool (QSAT) has been validated for faculty to assess residents in five categories: assessment; diagnostic actions; therapeutic actions; interpersonal communication, and overall assessment. We sought to determine whether the QSAT could be used to provide MSF using a standardized simulation case. METHODS: Prospectively after institutional review board approval, residents from a dual ACGME/osteopathic-approved postgraduate years (PGY) 1-4 EM residency were consented for participation. We developed a standardized resuscitation after overdose case with specific 1-5 Likert anchors used by the QSAT. A PGY 2-4 resident participated in the role of team leader, who completed a QSAT as self-assessment. The team consisted of a PGY-1 peer, an emergency medical services (EMS) provider, and a nurse. Two core faculty were present to administer the simulation case and assess. Demographics were gathered from all participants completing QSATs. We analyzed QSATs by each category and on cumulative score. Hypothesis testing was performed using intraclass correlation coefficients (ICC), with 95% confidence intervals. Interpretation of ICC results was based on previously published definitions. RESULTS: We enrolled 34 team leader residents along with 34 nurses. A single PGY-1, a single EMS provider and two faculty were also enrolled. Faculty provided higher cumulative QSAT scores than the other sources of MSF. QSAT scores did not increase with team leader PGY level. ICC for inter-rater reliability for all sources of MSF was 0.754 (0.572-0.867). Removing the self-evaluation scores increased inter-rater reliability to 0.838 (0.733-0.910). There was lesser agreement between faculty and nurse evaluations than from the EMS or peer evaluation. CONCLUSION: In this single-site cohort using an internally developed simulation case, the QSAT provided MSF with excellent reliability. Self-assessment decreases the reliability of the MSF, and our data suggest self-assessment should not be a component of MSF. Use of the QSAT for MSF may be considered as a source of data for clinical competency committees.

Tracking progress in suicide prevention in Indigenous communities: a challenge for public health surveillance in Canada.

Indigenous peoples in Canada experience disproportionate rates of suicide compared to non-Indigenous populations. Indigenous communities and organizations have designed local and regional approaches to prevention, and the federal government has developed a national suicide prevention framework. However, public health systems continue to face challenges in monitoring the population burden of suicide and suicidal behaviour. National health data systems lack Indigenous identifiers, do not capture data from some regions, and do not routinely engage Indigenous communities in data governance. These challenges hamper efforts to detect changes in population-level outcomes and assess the impact of suicide prevention activities. Consequently, this limits the ability to achieve public health prevention goals and reduce suicide rates and rate inequities.This paper provides a critical analysis of the challenges related to suicide surveillance in Canada and assesses the strengths and limitations of existing data infrastructure for monitoring outcomes in Indigenous communities. To better understand these challenges, we discuss the policy context for suicide surveillance and examine the survey and administrative data sources that are commonly used in public health surveillance. We then review recent data on the epidemiology of suicide and suicidal behaviour among Indigenous populations, and identify challenges related to national surveillance.To enhance capacity for suicide surveillance, we propose strategies to better track progress in Indigenous suicide prevention. Specifically, we recommend establishing an independent community and scientific governing council, integrating Indigenous identifiers into population health datasets, increasing geographic coverage, improving suicide data quality, comprehensiveness, and timeliness, and developing a platform for making suicide data accessible to all stakeholders. Overall, the strategies we propose can build on the strengths of the existing national suicide surveillance system by adopting a collaborative and inclusive governance model that recognizes the stake Indigenous communities have in suicide prevention.

Pathways to rural family practice at Memorial University of Newfoundland.

OBJECTIVE: To assess Memorial University of Newfoundland's (MUN's) commitment to a comprehensive pathways approach to rural family practice, and to determine the national and provincial effects of applying this approach. DESIGN: Analysis of anonymized secondary data. SETTING: Canada. PARTICIPANTS: Memorial's medical degree (MD) graduates practising family medicine in Newfoundland and Labrador as of January 2015 (N = 305), MUN's 2011 and 2012 MD graduates (N = 120), and physicians who completed family medicine training programs in Canada between 2004 and 2013 and who were practising in Canada 2 years after completion of their postgraduate training (N = 8091). MAIN OUTCOME MEASURES: National effect was measured by the proportion of MUN's family medicine program graduates practising in rural Canada compared with those from other Canadian family medicine training programs. Provincial effect was measured by the location of MUN's MD graduates practising family medicine in Newfoundland and Labrador as of January 2015. Commitment to a comprehensive pathways approach to rural family practice was measured by anonymized geographic data on admissions, educational placements, and practice locations of MUN's 2011 and 2012 MD graduates, including those who completed family medicine residencies at MUN. RESULTS: Memorial's comprehensive pathways approach to training physicians for rural practice was successful on both national and provincial levels: 26.9% of MUN family medicine program graduates were in a rural practice location 2 years after exiting their post-MD training from 2004 to 2013 compared with the national rate of 13.3% (national effect); 305 of MUN's MD graduates were practising family medicine in Newfoundland and Labrador as of 2015, with 36% practising in rural areas (provincial effect). Of 114 MD students with known background who graduated in 2011 and 2012, 32% had rural backgrounds. Memorial's 2011 and 2012 MD graduates spent 20% of all clinical placement weeks in rural areas; of note, 90% of all first-year placements and 95% of third-year family medicine clerkship placements were rural. For the 25 MUN 2011 and 2012 MD graduates who also completed family medicine residencies at MUN, 38% of family medicine placement weeks were spent in rural communities or rural towns. Of the 30 MUN 2011 and 2012 MD graduates practising family medicine in Canada as of January 2015, 42% were practising in rural communities or rural towns; 73% were practising in Newfoundland and Labrador and half of those were in rural communities and rural towns. CONCLUSION: A comprehensive rural pathways approach that includes recruiting rural students and exposing all medical students to extensive rural placements and all family medicine residents to rural family practice training has resulted in more rural generalist physicians in family practice in Newfoundland and Labrador and across Canada.

From pipelines to pathways: the Memorial experience in educating doctors for rural generalist practice.

CONTEXT: This report describes the community context, concept and mission of The Faculty of Medicine at Memorial University of Newfoundland (Memorial), Canada, and its 'pathways to rural practice' approach, which includes influences at the pre-medical school, medical school experience, postgraduate residency training, and physician practice levels. Memorial's pathways to practice helped Memorial to fulfill its social accountability mandate to populate the province with highly skilled rural generalist practitioners. Programs/interventions/initiatives: The 'pathways to rural practice' include initiatives in four stages: (1) before admission to medical school; (2) during undergraduate medical training (medical degree (MD) program); (3) during postgraduate vocational residency training; and (4) after postgraduate vocational residency training. Memorial's Learners & Locations (L&L) database tracks students through these stages. The Aboriginal initiative - the MedQuest program and the admissions process that considers geographic or minority representation in terms of those selecting candidates and the candidates themselves - occurs before the student is admitted. Once a student starts Memorial's MD program, the student has ample opportunities to have rural-based experiences through pre-clerkship and clerkship, of which some take place exclusively outside of St. John's tertiary hospitals. Memorial's postgraduate (PG) Family Medicine (FM) residency (vocational) training program allows for deeper community integration and longer periods of training within the same community, which increases the likelihood of a physician choosing rural family medicine. After postgraduate training, rural physicians were given many opportunities for professional development as well as faculty development opportunities. Each of the programs and initiatives were assessed through geospatial rurality analysis of administrative data collected upon entry into and during the MD program and PG training (L&L). Among Memorial MD-graduating classes of 2011-2020, 56% spent the majority of their lives before their 18th birthday in a rural location and 44% in an urban location. As of September 2016, 23 Memorial MD students self-identified as Aboriginal, of which 2 (9%) were from an urban location and 20 (91%) were from rural locations. For Year 3 Family Medicine, graduating classes 2011 to 2019, 89% of placement weeks took place in rural communities and 8% took place in rural towns. For Memorial MD graduating classes 2011-2013 who completed Memorial Family Medicine vocational training residencies, (N=49), 100% completed some rural training. For these 49 residents (vocational trainees), the average amount of time spent in rural areas was 52 weeks out of a total average FM training time of 95 weeks. For Family Medicine residencies from July 2011 to October 2016, 29% of all placement weeks took place in rural communities and 21% of all placement weeks took place in rural towns. For 2016-2017 first-year residents, 53% of the first year training is completed in rural locations, reflecting an even greater rural experiential learning focus. LESSONS LEARNED: Memorial's pathways approach has allowed for the comprehensive training of rural generalists for Newfoundland and Labrador and the rest of Canada and may be applicable to other settings. More challenges remain, requiring ongoing collaboration with governments, medical associations, health authorities, communities, and their physicians to help achieve reliable and feasible healthcare delivery for those living in rural and remote areas.

Does rural generalist focused medical school and family medicine training make a difference? Memorial University of Newfoundland outcomes.

INTRODUCTION: Rural recruitment and retention of physicians is a global issue. The Faculty of Medicine at Memorial University of Newfoundland, Canada, was established as a rural-focused medical school with a social accountability mandate that aimed to meet the healthcare needs of a sparse population distributed over a large landmass as well as the needs of other rural and remote areas of Canada. This study aimed to assess whether Memorial medical degree (MD) and postgraduate (PG) programs were effective at producing physicians for their province and rural physicians for Canada compared with other Canadian medical schools. METHODS: This retrospective cohort study included medical school graduates who completed their PG training between 2004 and 2013 in Canada. Practice locations of study subjects were georeferenced and assigned to three geographic classes: Large Urban; Small City/Town; and Rural. Analyses were performed at two levels. (1) Provincial level analysis compared Memorial PG graduates practicing where they received their MD and/or PG training with other medical schools who are the only medical school in their province (n=4). (2) National-level analysis compared Memorial PG graduates practicing in rural Canada with all other Canadian medical schools (n=16). Descriptive and bivariate analyses were performed. RESULTS: Overall, 18 766 physicians practicing in Canada completed Canadian PG training (2004-2013), and of those, 8091 (43%) completed Family Medicine (FM) training. Of all physicians completing Canadian PG training, 1254 (7%) physicians were practicing rurally and of those, 1076 were family physicians. There were 379 Memorial PG graduates and of those, 208 (55%) completed FM training and 72 (19%) were practicing rurally, and of those practicing rurally, 56 were family physicians. At the national level, the percentage of all Memorial PG graduates (19.0%) and FM PG graduates (26.9%) practicing rurally was significantly better than the national average for PG (6.4%, p<0.000) and FM (12.9%, p<0.000). Among 391 physicians practicing in Newfoundland and Labrador (NL), 257 (65.7%) were Memorial PG graduates and 247 (63.2%) were Memorial MD graduates. Of the 163 FM graduates, 148 (90.8%) were Memorial FM graduates and 118 (72.4%) were Memorial MD graduates. Of the 68 in rural practice, 51 (75.0%) were Memorial PG graduates and 31 (45.6%) were Memorial MD graduates. Of the 41 FM graduates in rural practice, 39 (95.1%) were Memorial FM graduates and 22 (53.7%) were Memorial MD graduates. Two-sample proportion tests demonstrated Memorial University provided a larger proportion of its provincial physician resource supply than the other four single provincial medical schools, by medical school MD for FM (72.4% vs 44.3%, p<0.000) and for overall (63.2% vs 43.5% p<0.000), and by medical school PG for FM (90.8 % vs 72.0%, p<0.000). CONCLUSION: This study found Memorial University graduates were more likely to establish practice in rural areas compared with the national average for most program types as well as more likely to establish practice in NL compared with other single medical schools' graduates in their provinces. This study highlights the impact a comprehensive rural-focused social accountability approach can have at supplying the needs of a population both at the regional and rural national levels.

Perception and Practice Among Emergency Medicine Health Care Providers Regarding Discharging Patients After Opioid Administration.

PURPOSE: This study aimed to determine the current attitudes, perceptions, and practices of emergency medicine providers and nurses (RNs) regarding the discharge of adult patients from the emergency department (ED) after administration of opioid analgesics. METHODS: A cross-sectional survey was administered at 3 hospital sites with a combined annual ED census of >180,000 visits per year. All 59 attending emergency physicians (EPs), 233 RNs, and 23 advanced practice clinicians (APCs) who worked at these sites were eligible to participate. FINDINGS: Thirty-five EPs (59.3%), 88 RNs (37.8%), and 14 APCs (60.9%) completed the survey for an overall response rate of 51.75%. Most respondents were female (95 [69.9%]). The factor ranked most important to consider when discharging a patient from the ED after administration of opioids was the patient's functional status and vital signs (median, 2.00; interquartile range, 2.00-3.50). More RNs (84 [96.6%]) than EPs (29 [82.9%]) reported that developing an ED policy or guideline for safe discharge after administration of opioids is important to clinical practice (P = 0.02). Only 8 physicians (23.5%) reported that they did not prescribe intramuscular morphine, and 15 (42.9%) reported that they did not prescribe intramuscular hydromorphone. EPs (7 [20.0%]) and RNs (3 [3.4%]) differed in regard to whether they were aware if any patients to whom they administered an opioid had experienced an adverse drug-related event (P = 0.01). Most EPs (24 [68.6%]) and RNs (54 [61.4%]) believed that the decision for patient discharge should be left to both the emergency medicine provider and the RN. IMPLICATIONS: Most study participants believed that developing a policy or guideline for safe discharge after administration opioids in the ED is important to clinical practice. Only a few physicians reported that they did not prescribe intramuscular hydromorphone or morphine. Most participants believed the discharge decision after administration of opioids in the ED should be primarily determined by both the emergency medicine provider and the RN.

Suicide Rates in Aboriginal Communities in Labrador, Canada.

OBJECTIVES: To compare suicide rates in Aboriginal communities in Labrador, including Innu, Inuit, and Southern Inuit, with the general population of Newfoundland, Canada. METHODS: In partnership with Aboriginal governments, we conducted a population-based study to understand patterns of suicide mortality in Labrador. We analyzed suicide mortality data from 1993 to 2009 from the Vital Statistics Death Database. We combined this with community-based methods, including consultations with Elders, youths, mental health and community workers, primary care clinicians, and government decision-makers. RESULTS: The suicide rate was higher in Labrador than in Newfoundland. This trend persisted across all age groups; however, the disparity was greatest among those aged 10 to 19 years. Males accounted for the majority of deaths, although suicide rates were elevated among females in the Inuit communities. When comparing Aboriginal subregions, the Innu and Inuit communities had the highest age-standardized mortality rates of, respectively, 165.6 and 114.0 suicides per 100 000 person-years. CONCLUSIONS: Suicide disproportionately affects Innu and Inuit populations in Labrador. Suicide rates were high among male youths and Inuit females.

Transforming Health Care in Remote Communities: report on an international conference.

An international conference titled "Transforming Health Care in Remote Communities" was held at the Chateau Lacombe Hotel in Edmonton, Canada, April 28-30, 2016. The event was organized by the University of Alberta's School of Public Health, in partnership with the Institute for Circumpolar Health Research in Yellowknife, Northwest Territories, and the Qaujigiartiit Health Research Centre in Iqaluit, Nunavut. There were 150 registrants from 7 countries: Canada (7 provinces and 3 territories), United States, Denmark, Iceland, Norway, Sweden, and Australia. They included representatives of academic institutions, health care agencies, government ministries, community organizations, and private industry. The Conference focused on developing solutions to address health care in remote regions. It enabled new networks to be established and existing ones consolidated.

A scoping review of Indigenous suicide prevention in circumpolar regions.

BACKGROUND: Suicide is a serious public health challenge in circumpolar regions, especially among Indigenous youth. Indigenous communities, government agencies and health care providers are making concerted efforts to reduce the burden of suicide and strengthen protective factors for individuals, families and communities. The persistence of suicide has made it clear that more needs to be done. OBJECTIVE: Our aim was to undertake a scoping review of the peer-reviewed literature on suicide prevention and interventions in Indigenous communities across the circumpolar north. Our objective was to determine the extent and types of interventions that have been reported during past decade. We want to use this knowledge to support community initiative and inform intervention development and evaluation. DESIGN: We conducted a scoping review of online databases to identify studies published between 2004 and 2014. We included articles that described interventions in differentiated circumpolar Indigenous populations and provided evaluation data. We retained grey literature publications for comparative reference. RESULTS: Our search identified 95 articles that focused on suicide in distinct circumpolar Indigenous populations; 19 articles discussed specific suicide-related interventions and 7 of these described program evaluation methods and results in detail. The majority of publications on specific interventions were found in North American countries. The majority of prevention or intervention documentation was found in supporting grey literature sources. CONCLUSION: Despite widespread concern about suicide in the circumpolar world and active community efforts to promote resilience and mental well-being, we found few recorded programs or initiatives documented in the peer-reviewed literature, and even fewer focusing specifically on youth intervention. The interventions described in the studies we found had diverse program designs and content, and used varied evaluation methods and outcomes. The studies we included consistently reported that it was important to use community-based and culturally guided interventions and evaluations. This article summarizes the current climate of Indigenous circumpolar suicide research in the context of intervention and highlights how intervention-based outcomes have largely remained outside of peer-reviewed sources in this region of the world.

The use of remote presence for health care delivery in a northern Inuit community: a feasibility study.

OBJECTIVE: To evaluate the feasibility of remote presence for improving the health of residents in a remote northern Inuit community. STUDY DESIGN: A pilot study assessed patient's, nurse's and physician's satisfaction with and the use of the remote presence technology aiding delivery of health care to a remote community. A preliminary cost analysis of this technology was also performed. METHODS: This study deployed a remote presence RP-7 robot to the isolated Inuit community of Nain, Newfoundland and Labrador for 15 months. The RP-7 is wirelessly controlled by a laptop computer equipped with audiovisual capability and a joystick to maneuver the robot in real time to aid in the assessing and care of patients from a distant location. Qualitative data on physician's, patient's, caregiver's and staff's satisfaction were collected as well as information on its use and characteristics and the number of air transports required to the referral center and associated costs. RESULTS: A total of 252 remote presence sessions occurred during the study period, with 89% of the sessions involving direct patient assessment or monitoring. Air transport was required in only 40% of the cases that would have been otherwise transported normally. Patients and their caregivers, nurses and physicians all expressed a high level of satisfaction with the remote presence technology and deemed it beneficial for improved patient care, workloads and job satisfaction. CONCLUSIONS: These results show the feasibility of deploying a remote presence robot in a distant northern community and a high degree of satisfaction with the technology. Remote presence in the Canadian North has potential for delivering a cost-effective health care solution to underserviced communities reducing the need for the transport of patients and caregivers to distant referral centers.

Needs of specialists in rural and remote Canada.

INTRODUCTION: Very little literature exists on rural specialists as a unique group and how best to meet their needs. We sought to provide some baseline information on specialists practising in rural and remote Canada to better understand their reasons for working rurally, their workload and how supported they felt, as well as their sources of advice and satisfaction with continuing medical education (CME). METHODS: The Society of Rural Physicians of Canada mailed a survey to specialists working in rural and remote Canada. Specialists were identified based on databases of the Canadian Medical Association (CMA) and the provincial colleges. The survey focused on reason(s) for working in a rural or remote setting, level of support and CME. RESULTS: The survey was sent to 1500 physicians and yielded a 19% response rate. Although 85% of respondents felt supported overall, less than 20% felt supported by the CMA or by the Royal College of Physicians and Surgeons of Canada (RCPSC). Conversely, most felt supported by immediate colleagues (85%) and their community (78%). Most wished they had access to more training, with close to 90% agreeing that additional training should be available if they had worked for several years in a rural or remote area and a need was demonstrated. CONCLUSION: The CMA and the RCPSC may wish to work with rural specialists to foster a more supportive relationship and better meet their needs. Additionally, efforts should be made to provide rural specialists with better access to relevant CME.

Resuscitation by video in northern communities.

OBJECTIVES: This paper describes the set-up of a videoconference system to support resuscitation in remote communities and the outcome of the video support. STUDY DESIGN: A case study examining the use of videoconferencing to lead life support remotely. METHODS: Resuscitations in these communities were led remotely by a physician through videoconferencing. The videoconference unit is set up in the corner of the room for optimal viewing of the patient and the monitors. The keys to success are a secure 512 kbps broadband service, user-friendly videoconference units and appropriate training. RESULTS: Over the past 3 years in Labrador, 6 patients with major trauma, pulseless tachyarrhythmias, cardiogenic shock, septic shock and severe hypothermia were successfully resuscitated. CONCLUSION: Oversight of life support via videoconferencing with the right set-up and training can lead to successful resuscitation in remote communities.

A highly adaptable catalyst/substrate system for the synthesis of substituted chromenes.

The gold(I)-catalyzed endo-cyclization of o-(1-hydroxyallyl)phenols to form chromenes is reported. The title compounds are prepared in high yield from readily available substrates. The system tolerates both electron rich and deficient aryl rings and a high degree of substitution on the allyl moiety.

Recruitment trumps retention: results of the 2008/09 CMA Rural Practice Survey.

INTRODUCTION: In 2008, the Canadian Medical Association (CMA) conducted a survey of rural practitioners. The survey covered incentives to choose rural medicine, current satisfaction, plans for future migration and strategies for retention. METHODS: The CMA Canadian Collaborative Centre for Physician Resources, in collaboration with the Society of Rural Physicians of Canada, surveyed 1960 rural practitioners and received 642 responses (33% response rate). Because of similarities with earlier surveys, longitudinal analyses were possible. RESULTS: More than 70% of physicians older than 45 years received no incentives for setting up rural practice, compared with 41% of younger physicians. Younger physicians attached greater importance to financial incentives than older physicians, but personal incentives, such as accommodations in the community, were also important. The opportunity to practise one's full skill set was considered important (84%) as was liking the lifestyle (82%). One in 7 (14%) respondents planned to move from their communities within the next 2 years. They reported they might stay if they had a more reasonable workload, professional backup and locums. CONCLUSION: Although increasingly common, cash incentives are not the main reason physicians choose rural practice. Practice and lifestyle factors are even more important. Communities need to focus as much on retention issues to protect their investment in the long term.

Identification of crab proteins that elicit IgE reactivity in snow crab-processing workers.

BACKGROUND: The expanding snow crab-processing industry has resulted in increased numbers of workers at risk of occupational allergy. OBJECTIVE: Our study is to identify relevant allergenic proteins in cooked snow crab meat (CM) and crab water (CW) used for cooking for improved remediation, diagnosis, and treatment. METHODS: Extracts were prepared from CM extracts, CW extracts, and an air-filter collection near the crab cooker. Of the 207 workers, 24 with the highest IgE antibody reactivity to CM and CW extracts, as determined by using RASTs, were tested for reactivity to nitrocellulose membranes containing CM and CW proteins separated with SDS-PAGE. A 3-serum pool was similarly incubated against nitrocellulose-bound proteins from air samples collected near the crab cooker. RESULTS: Of the 207 sera tested, 27 and 39 sera exhibited positive IgE antibody reactivity (>or=2%) to CM and CW extracts, respectively. Twenty-two of 24 sera with the highest RAST activity (>or=3.5% binding) demonstrated IgE binding to multiple proteins (13.6-50 kd). A majority of the sera reacted to 4 proteins: 79% and 71% to a 34.0-kd protein, 79% and 42% to a 25-kd protein, 67% and 71% to an 18.5-kd protein, and 75% to a 14.4-kd protein in both CM and CW extracts, respectively. The pool of IgE-positive sera blotted against the air-filter extract reacted to 14.4-, 18.5-, 34.0-, 43.2-, and 50-kd proteins present in both crab extracts. CONCLUSION: Four major IgE-reactive proteins were identified in CM extracts, CW extracts, and air-filter eluate. Analysis of any potential association of protein reactivity with disease suggested crab proteins at 34.0 and 14.4 kd might be more relevant.
