RESUMO

BACKGROUND: Inflammation is a key mediator in the development and progression of the atherosclerotic disease process as well as its resultant complications, like myocardial infarction (MI), stroke and cardiovascular (CV) death, and is emerging as a novel treatment target. Trials involving anti-inflammatory medications have demonstrated outcome benefit in patients with known CV disease. In this regard, colchicine appears to hold great promise. However, there are potential drawbacks to colchicine use, as some studies have identified an increased risk of infection, and a non-significant trend for increased all-cause mortality. Thus, a more thorough understanding of the underlying mechanism of action of colchicine is needed to enable a better patient selection for this novel CV therapy. OBJECTIVE: The primary objective of the Canadian Study of Arterial Inflammation in Patients with Diabetes and Recent Vascular Events, Evaluation of Colchicine Effectiveness (CADENCE) trial is to assess the effect of colchicine on vascular inflammation in the carotid arteries and ascending aorta measured with 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET)/CT in patients with type 2 diabetes mellitus (T2DM) or pre-diabetes who have experienced a recent vascular event (acute coronary syndrome (ACS)/MI, transient ischaemic attack (TIA) or stroke). Secondary objectives include determining colchicine's effect on inflammatory biomarkers (high-sensitivity C reactive protein (hs-CRP) and interleukin-6 (IL-6)). Additionally, we will assess if baseline inflammation imaging or biomarkers are associated with a treatment response to colchicine determined by imaging. Exploratory objectives will look at: (1) the difference in the inflammatory response to colchicine in patients with coronary events compared with patients with cerebral events; (2) the difference in the inflammatory response to colchicine in different vascular beds; (3) the relationship of FDG-PET imaging markers with serum biomarkers and (4) assessment of quality-of-life changes. METHODS AND DESIGN: CADENCE is a multicentre, prospective, randomised, double-blinded, placebo-controlled study to determine the effect of colchicine on arterial inflammation as assessed with imaging and circulatory biomarkers, specifically carotid arteries and aortic FDG uptake as well as hs-CRP and IL-6 among others. Patients with T2DM or pre-diabetes who have recently experienced a CV event (within 30-120 days after an ACS (ie, ST-elevation MI (STEMI) or non-STEMI)) or TIA/stroke with documented large vessel atherosclerotic disease will be randomised to treatment with either colchicine 0.6 mg oral daily or placebo. Participants will undergo baseline clinical evaluation including EQ5D assessment, blood work for inflammatory markers and FDG PET/CT scan of the ascending aorta and left and right carotid arteries. Patients will undergo treatment for 6 months and have repeat clinical evaluation including EQ5D assessment, blood work for inflammatory markers and FDG PET/CT scan at the conclusion of the study. The primary outcome will be the change in the maximum target to background ratio (TBRmax) in the ascending aorta (or carotid arteries) from baseline to follow-up on FDG PET/CT imaging. DISCUSSION: Colchicine is an exciting potential new therapy for CV risk reduction. However, its use is associated with side effects and greater understanding of its underlying mechanism of action is needed. Importantly, the current study will determine whether its anti-inflammatory action is an indirect systemic effect, or a more local plaque action that decreases inflammation. The results will also help identify patients who will benefit most from such therapy. TRIAL REGISTRATION NUMBER: NCT04181996.

RESUMO

AIM: Non-surgical options for inducing type 2 diabetes remission are limited. We examined whether remission can be achieved by combining lifestyle approaches and short-term intensive glucose-lowering therapy. METHODS: In this trial, 160 patients with type 2 diabetes on none to two diabetes medications other than insulin were randomised to (a) an intervention comprising lifestyle approaches, insulin glargine/lixisenatide and metformin, or (b) standard care. Participants with glycated haemoglobin (HbA1c) <7.3% (56 mmol/mol) at 12 weeks were asked to stop diabetes medications and were followed for an additional 52 weeks. The primary outcome was diabetes relapse defined as HbA1c ≥6.5% (48 mmol/mol) at 24 weeks or thereafter, capillary glucose ≥10 mmol/L on ≥50% of readings, or use of diabetes medications, analysed as time-to-event. Main secondary outcomes included complete or partial diabetes remission at 24, 36, 48 and 64 weeks defined as HbA1c <6.5% (48 mmol/mol) off diabetes medications since 12 weeks after randomisation. A hierarchical testing strategy was applied. RESULTS: The intervention significantly reduced the hazard of diabetes relapse by 43% (adjusted hazard ratio 0.57, 95% confidence interval 0.40-0.81; p = .002). Complete or partial diabetes remission was achieved in 30 (38.0%) intervention group participants versus 16 (19.8%) controls at 24 weeks and 25 (31.6%) versus 14 (17.3%) at 36 weeks [relative risk 1.92 (95% confidence interval 1.14-3.24) and 1.83 (1.03-3.26), respectively]. The relative risk of diabetes remission in the intervention versus control group was 1.88 (1.00-3.53) at 48 weeks and 2.05 (0.98-4.29) at 64 weeks. CONCLUSIONS: A 12-week intensive intervention comprising insulin glargine/lixisenatide, metformin and lifestyle approaches can induce remission of diabetes.

RESUMO

INTRODUCTION: Health professions education often includes teaching observation to inform faculty development (FD) and indirectly improve student performance. Although these FD approaches are well received by faculty, they remain underused and/or underreported, with limited opportunities to receive feedback in workplace contexts. The goal of our study was to map the depth and breadth of education literature on the use of observation of teaching as a tool of professional development in medical education. METHODS: Following the methodology by Arksey and O'Malley, we conducted a scoping review and searched four databases for articles published in English (final searches in April 2022). RESULTS: Of 2080 articles identified, 45 met the inclusion criteria. All observation activities were associated with one of the following FD approaches: peer observation of teaching (23 articles, 51%), peer coaching (12, 27%), peer review (9, 20%), and the critical friends approach (1, 2%). Thirty-three articles (73%) concerned formative versions of the observation model that took place in clinical settings (21, 47%), and they tended to be a voluntary (27, 60%), one-off (18, 40%), in-person intervention (29, 65%), characterized by limited institutional support (13, 29%). Both barriers and challenges of teaching observation were identified. DISCUSSION: This review identified several challenges and shortcomings associated with teaching observation, such as inadequate methodological quality of research articles, inconsistent terminology, and limited understanding of the factors that promote long-term sustainability within FD programs. Practical strategies to consider when designing an FD program that incorporates teaching observation are outlined.

RESUMO

BACKGROUND: Immune checkpoint inhibitor (ICI)-associated hypothalamic-pituitary-adrenal axis disruption can lead to hypocortisolism. This is a life-threatening but difficult to diagnose condition, due to its non-specific symptoms that overlap with symptoms of malignancy. Currently, there is no consensus on how to best screen asymptomatic patients on ICI therapy for hypophysitis with serum cortisol. METHODS: A retrospective chart review of patients treated with ICI in a tertiary care centre was conducted to assess the rate of screening with cortisol and whether this had an impact on diagnosis of ICI-hypophysitis in the preclinical stage. Patients were identified as having hypophysitis with an adrenocorticotropin hormone (ACTH) deficiency based on chart review of patients with cortisol values ≤ 140 nmol/L (≤5 mcg/dL). We also assessed what proportion of cortisol values were drawn at the correct time for interpretation (between 6 AM and 10 AM). RESULTS: Two hundred and sixty-five patients had 1301 cortisol levels drawn, only 40% of which were drawn correctly (between 6 and 10 AM). Twenty-two cases of hypophysitis manifesting with ACTH deficiency were identified. Eight of these patients were being screened with cortisol following treatment and were detected in the outpatient setting. The remaining 14 patients were not screened and were diagnosed when symptomatic, after an emergency room visit or hospital admission. Sixty percent of the cortisol tests were uninterpretable as they were not drawn within the appropriate time window. CONCLUSION: Measuring morning serum cortisol in asymptomatic patients on ICI therapy is a fast and inexpensive way to screen for hypophysitis and should become the standard of care. Random serum cortisol measurement has no clinical value. Education needs to be provided on when to correctly perform the test and how to interpret it and we provide an algorithm for this purpose. The adoption and validation of such an algorithm as part of routine practice could significantly reduce morbidity and mortality in patients, especially as ICI therapy is becoming increasingly commonplace.

RESUMO

OBJECTIVES: Contemporary guidelines suggest relaxed glycemic targets in populations with type 2 diabetes mellitus (T2DM) at risk of hypoglycemia, including people with multimorbidity, limited life expectancy or frailty. However, overtreatment remains commonplace. To inform safe deprescribing, a previous systematic review investigated the benefits and harms of deprescribing antihyperglycemics, but identified only limited, very low-quality evidence. We sought to update that review and identify and describe newly published literature on the effects of deprescribing antihyperglycemics in older adults with T2DM. METHODS: We searched MEDLINE, EMBASE and the Cochrane Library (July 2015 to January 2021) for controlled studies published in English addressing the effects of deprescribing vs continuing antihyperglycemics in adults with T2DM. Two independent reviewers performed title, abstract and full-text screening, data extraction and risk-of-bias assessment. Cochrane's risk-of-bias tools, RoB 2 and ROBINS-I, were used. The findings were summarized narratively. GRADE (Grading of Recommendations, Assessment, Development and Evaluations) was used to evaluate the evidence. RESULTS: We identified 4 additional investigations-2 randomized controlled trials and 2 retrospective cohort studies. After deprescribing, 3 studies reported no clinically significant changes in glucose management and 2 studies reported reductions in adverse events (e.g. hypoglycemia, all-cause mortality and nonspine fractures). However, based on GRADE assessment, we found very low certainty of the evidence due to concerns of risk of bias (e.g. unmeasured confounding), imprecision, and indirectness. CONCLUSIONS: Deprescribing antihyperglycemic medications in older adults with T2DM is likely feasible and safe, and benefits may outweigh the harms. However, the evidence indicates very low certainty. Additional deprescribing studies are needed with rigorous methodologies and reporting.

RESUMO

Background: Over the last 31 years, there have been several institutional efforts to better recognize and reward clinician teachers. However, the perception of inadequate recognition and rewards by clinician teachers for their clinical teaching performance and achievements remains. The objective of this narrative review is two-fold: deepen understanding of the attributes of excellent clinician teachers considered for recognition and reward decisions and identify the barriers clinician teachers face in receiving recognition and rewards. Methods: We searched OVID Medline, Embase, Education Source and Web of Science to identify relevant papers published between 1990 and 2020. After screening for eligibility, we conducted a content analysis of the findings from 43 relevant papers to identify key trends and issues in the literature. Results: We found the majority of relevant papers from the US context, a paucity of relevant papers from the Canadian context, and a declining international focus on the attributes of excellent clinician teachers and barriers to the recognition and rewarding of clinician teachers since 2010. 'Provides feedback', 'excellent communication skills', 'good supervision', and 'organizational skills' were common cognitive attributes considered for recognition and rewards. 'Stimulates', 'passionate and enthusiastic', and 'creates supportive environment', were common non-cognitive attributes considered for recognition and rewards. The devaluation of teaching, unclear criteria, and unreliable metrics were the main barriers to the recognition and rewarding of clinician teachers. Conclusions: The findings of our narrative review highlight a need for local empirical research on recognition and reward issues to better inform local, context-specific reforms to policies and practices.


Contexte: Depuis 31 ans, nous sommes témoins d'efforts institutionnels visant à offrir aux cliniciens enseignants une plus grande reconnaissance et à récompenser leur travail. Cependant, d'après leur perception, la valorisation de leurs réalisations en matière d'enseignement clinique demeure insuffisante. Cette revue narrative a un double objectif : d'une part, repérer les qualités qui sont prises en considération en vue de l'octroi d'une reconnaissance officielle ou de l'attribution de récompenses (prix) aux cliniciens enseignants et d'autre part recenser les éléments qui empêchent certains candidats de se voir accorder une telle reconnaissance ou récompense. Méthodes: Nous avons effectué des recherches dans OVID Medline, Embase, Education Source et Web of Science pour repérer les articles pertinents publiés entre 1990 et 2020. Le contenu des résultats des 43 articles sélectionnés a ensuite été analysé pour dégager les principales tendances et questions abordées. Résultats: La plupart des articles pertinents se rapportaient au contexte des États-Unis. En revanche, peu d'articles pertinents concernaient celui du Canada. Sur le plan international, la question des qualités des cliniciens enseignants et des éléments qui peuvent les empêcher d'obtenir la reconnaissance ou une récompense suscite moins d'intérêt depuis 2010. Le fait « d'offrir de la rétroaction ¼, d'avoir « d'excellentes habiletés de communication ¼, d'assurer une « bonne supervision ¼, et un bon « sens de l'organisation ¼ sont des compétences cognitives souvent considérées pour l'octroi de la reconnaissance et l'attribution de récompenses. Parmi les compétences non cognitives, on note le fait d'être « stimulant ¼, d'être « passionné et enthousiaste ¼ et de « créer un environnement offrant du soutien ¼. La dévalorisation de l'enseignement, le manque de critères clairs et l'utilisation de mesures d'évaluation peu fiables sont les principaux obstacles à l'octroi de la reconnaissance ou à l'attribution d'une récompense aux cliniciens enseignants. Conclusions: Les résultats de notre revue narrative mettent en évidence la nécessité de mener des recherches empiriques localement en matière de reconnaissance et de récompense afin d'éclairer les réformes locales des politiques et des pratiques dans le milieu spécifique où elles sont appliquées.

RESUMO

OBJECTIVE: There is a paucity of literature on the impact of bariatric surgery on artificial reproductive technology (ART) outcomes. This topic should be examined, given that most bariatric surgery candidates are of reproductive age and those with obesity are significantly more likely to experience poor fertility outcomes. This systematic review aimed to determine if bariatric surgery impacts ART outcomes and if effects vary between females and males. DATA SOURCES: MEDLINE, EMBASE, SCOPUS, and the Cochrane Central Register of Controlled Trials were searched for English studies published between January 1978 and May 2021. STUDY SELECTION: Studies with participants who had received bariatric surgery and subsequently underwent ART (i.e., in vitro fertilization or intracytoplasmic sperm injection) were eligible for inclusion. Screening, data abstraction, and risk of bias assessment were conducted independently and in duplicate. DATA EXTRACTION AND SYNTHESIS: Of the 279 articles screened for eligibility, 25 were sought for full text review, and 7 were included for analysis. Four studies (57%) examined ART interventions in females, while 3 (43%) examined interventions in males. Data on cumulative live birth rate (CLBR) was extracted for all 7 studies (N = 169). There were 50 live births with CLBRs ranging from 0.0% to 80.0%. Data on female secondary outcomes were varied. Data on male secondary outcomes were contradictory: 1 study indicated improved sperm parameters following bariatric surgery, while 2 showed decreased parameters, with certain participants seeing improvements after several months. CONCLUSION: Bariatric surgery prior to ART may have an impact on CLBRs; however, high-quality research is needed to delineate the direct effects of bariatric surgery on ART outcomes. Various sex-specific outcomes should be considered prior to recommending ART after bariatric surgery. Future research should determine the optimal type of bariatric surgery and timing of ART following bariatric surgery.

RESUMO

PURPOSE: To assess reported rates of gastrointestinal (GI) symptoms and their association with autoimmune diseases and microvascular complications in adults and children with type 1 diabetes. METHODS: The Gastrointestinal Symptom Scale was used to assess GI symptom type and severity in 2370 patients with type 1 diabetes aged 8 to 45 years evaluated as part of a clinical trial screening for celiac disease (CD). The presence and severity of GI symptoms and relationships with demographic, clinical, and other diabetes-related factors were evaluated. RESULTS: Overall, 1368 adults (57.7%) aged 19 to 45 years and 1002 (42.3%) pediatric patients aged 8 to 18 years were studied. At least 1 GI symptom was reported in 34.1% of adults as compared with 21.7% of children (P < 0.0001). Common symptoms in children included upper and lower abdominal pain while adults more frequently reported lower GI symptoms. Participants with GI symptoms had higher hemoglobin A1c (HbA1c) levels (68 ±â€…14mmol/mol; 8.35 ±â€…1.37%) than those without symptoms (66 ±â€…15mmol/mol; 8.22 ±â€…1.40%; P = 0.041). Patients with microvascular complications (nephropathy, retinopathy, and/or neuropathy) were 1.8 times more likely to report GI symptoms (95% CI: 1.26-2.60; P < 0.01) after adjusting for age and sex. No association was observed between GI symptoms and the presence of autoimmune conditions, including thyroid and biopsy-confirmed CD (odds ratio = 1.1; 95% CI: 0.86-1.42; P = 0.45). MAIN CONCLUSIONS: These results highlight that GI symptoms are an important clinical morbidity and are associated with increasing age, duration of type 1 diabetes, HbA1c, and microvascular complications but not with autoimmune comorbidities including CD.

RESUMO

BACKGROUND: Individuals with obesity are at higher risk of experiencing complications during their pregnancy and may also experience infertility, requiring assisted reproductive technologies (ART) to conceive. The current body of literature demonstrates that bariatric surgery decreases an individual's risk of developing a variety of obesity-related obstetrical conditions during and after pregnancy. However, the effects of bariatric surgery on ART outcomes are not well understood. Therefore, the paucity in the literature warrants a need to determine these effects. METHODS: We will search electronic databases, including MEDLINE, Embase, Scopus, and Cochrane Central Register of Controlled Trials (CENTRAL), as well as the gray literature and the reference lists of included articles. We will screen all studies published between January 1978 and the present day that explore the impact of bariatric surgery on ART outcomes for women and men. We will include observational studies. Two independent reviewers will assess the studies for inclusion and extract data for each article. The main outcome that will be analyzed is live birth rate. Secondary outcomes such as time to conception, number of rounds of ART, type of bariatric surgery, and length of time between bariatric surgery and initiation of ART will also be recorded. Risk of bias will be conducted using the National Institutes of Health Study Quality Assessment Tools. A random effects model will be used to account for statistical analysis and results will be pooled with forest plots. In the event of statistical and reporting heterogeneity, we will provide a qualitative synthesis and narrative review of the results. DISCUSSION: This review will provide information on the outcomes of ART following bariatric surgery and may help healthcare professionals make informed decisions about the length of time between bariatric surgery and initiation of ART. The study findings may be of interest to various stakeholders including patients, bariatric surgeons, obstetricians, and gynecologists, and those who specialize in obesity medicine and reproductive endocrinology and infertility. We plan to disseminate our findings through presentations, publications, and social media releases to individuals who are navigating infertility and are interested in undergoing or have undergone bariatric surgery, healthcare professionals, policymakers, and researchers.

RESUMO

CONTEXT: Celiac disease (CD) is a common comorbidity seen in patients with type 1 diabetes (T1D) and is frequently asymptomatic. As chronic conditions requiring significant lifestyle changes, there are limited reports assessing changes in health-related quality of life (HRQoL) during transition to a gluten-free diet (GFD) in patients with T1D who are asymptomatic for CD. OBJECTIVE: This work aims to prospectively assess HRQoL and health perception in children and adults with T1D and asymptomatic CD after random assignment to GFD vs usual diet. METHODS: Patients with T1D aged 8 to 45 years without CD symptoms were serologically screened for CD, with positive results confirmed with intestinal biopsy. Participants were randomly assigned in an open-label fashion to a GFD or gluten-containing diet (GCD) for 12 months. Generic and diabetes-specific HRQoL and self-perceived wellness (SPW) were assessed longitudinally. RESULTS: A total of 2387 T1D patients were serologically screened. CD was biopsy-confirmed in 82 patients and 51 participants were randomly assigned to a GFD (N = 27) or GCD (N = 24). Excellent adherence to the assigned diets was observed. Overall, no changes in generic (P = .73) or diabetes-specific HRQoL (P = .30), or SPW (P = .41) were observed between groups over 12 months. Hemoglobin A1c (HbA1c) and gastrointestinal symptoms were consistent predictors of HRQoL and SPW. CONCLUSION: HRQoL and SPW were not significantly affected by the adoption of a GFD over 12 months, but worsened with symptom onset and increased HbA1c. Our findings indicate that transition to a GFD can be made successfully in this population without adversely affecting quality of life.

RESUMO

OBJECTIVE: To describe celiac disease (CD) screening rates and glycemic outcomes of a gluten-free diet (GFD) in patients with type 1 diabetes who are asymptomatic for CD. RESEARCH DESIGN AND METHODS: Asymptomatic patients (8-45 years) were screened for CD. Biopsy-confirmed CD participants were randomized to GFD or gluten-containing diet (GCD) to assess changes in HbA1c and continuous glucose monitoring over 12 months. RESULTS: Adults had higher CD-seropositivity rates than children (6.8% [95% CI 4.9-8.2%, N = 1,298] vs. 4.7% [95% CI 3.4-5.9%, N = 1,089], P = 0.035) with lower rates of prior CD screening (6.9% vs. 44.2%, P < 0.0001). Fifty-one participants were randomized to a GFD (N = 27) or GCD (N = 24). No HbA1c differences were seen between the groups (+0.14%, 1.5 mmol/mol; 95% CI -0.79 to 1.08; P = 0.76), although greater postprandial glucose increases (4-h +1.5 mmol/L; 95% CI 0.4-2.7; P = 0.014) emerged with a GFD. CONCLUSIONS: CD is frequently observed in asymptomatic patients with type 1 diabetes, and clinical vigilance is warranted with initiation of a GFD.

RESUMO

PURPOSE: To examine the extent, range, and nature of how competency-based medical education (CBME) implementation terminology is used (i.e., the conceptualization of CBME-related terms) within the family medicine postgraduate medical education (PGME) and continuing professional development (CPD) literature. METHOD: This scoping review's methodology was based on Arksey and O'Malley's framework and subsequent recommendations by Tricco and colleagues. The authors searched 5 databases and the gray literature for U.S. and Canadian publications between January 2000 and April 2017. Full-text English-language articles on CBME implementation that focused exclusively on family medicine PGME and/or CPD programs were eligible for inclusion. A standardized data extraction form was used to collect article demographic data and coding concepts data. Data analysis used mixed methods, including quantitative frequency analysis and qualitative thematic analysis. RESULTS: Of 470 unique articles identified, 80 (17%) met the inclusion criteria and were selected for inclusion in the review. Only 12 (15%) of the 80 articles provided a referenced definition of the coding concepts (i.e., referred to an article/organization as the definition's source), resulting in 19 highly variable-and 12 unique- referenced definitions of key terms used in CBME implementation (competence, competency, competency-based medical education). Thematic analysis of the referenced definitions identified 15 dominant themes, among which the most common were (1) a multidimensional and dynamic concept that encompasses a variety of skill components and (2) being able to use communication, knowledge, technical skills, clinical reasoning, judgment, emotions, attitudes, personal values, and reflection in practice. CONCLUSIONS: The construction and dissemination of shared definitions is essential to CBME's successful implementation. The low number of referenced definitions and lack of consensus on such definitions suggest more attention needs to be paid to conceptual rigor. The authors recommend those involved in family medicine education work with colleagues across medical specialties to develop a common taxonomy.

RESUMO

Objective: To clarify the selection of medical therapy following transsphenoidal surgery in patients with acromegaly, based on growth hormone (GH)/insulin-like growth factor 1 (IGF-1) response and glucometabolic control. Methods: We carried out a systematic literature review on three of the best studied and most practical predictive markers of the response to somatostatin analogues (SSAs): somatostatin receptor (SSTR) expression, tumor morphologic classification, and T2-weighted magnetic resonance imaging (MRI) signal intensity. Additional analyses focused on glucose metabolism in treated patients. Results: The literature survey confirmed significant associations of all three factors with SSA responsiveness. SSTR expression appears necessary for the SSA response; however, it is not sufficient, as approximately half of SSTR2-positive tumors failed to respond clinically to first-generation SSAs. MRI findings (T2-hypo-intensity) and a densely granulated phenotype also correlate with SSA efficacy, and are advantageous as predictive markers relative to SSTR expression alone. Glucometabolic control declines with SSA monotherapy, whereas GH receptor antagonist (GHRA) monotherapy may restore normoglycemia. Conclusion: We propose a decision tree to guide selection among SSAs, dopamine agonists (DAs), and GHRA for medical treatment of acromegaly in the postsurgical setting. This decision tree employs three validated predictive markers and other clinical considerations, to determine whether SSAs are appropriate first-line medical therapy in the postsurgical setting. DA treatment is favored in patients with modest IGF-1 elevation. GHRA treatment should be considered for patients with T2-hyperintense tumors with a sparsely granulated phenotype and/or low SSTR2 staining, and may also be favored for individuals with diabetes. Prospective analyses are required to test the utility of this therapeutic paradigm.

RESUMO

This article was migrated. The article was marked as recommended. There is a growing worldwide awareness in the field of health professions education and research that a successful implementation of competency-based medical education (CBME) requires embracing all stages of professional development (from undergraduate, through residency to continuing education). However, despite increased levels of cognizance and even enthusiasm about the importance of the entire continuum for the ultimate goal of improved healthcare, much work still remains as CBME principles are not widely adopted in continuing professional development (CPD). Much has been written about the process of competency-based curriculum development (e.g., the formation and development of meaningful and measurable outcomes) in undergraduate studies and postgraduate training, but not in CPD. If we expect a CPD curriculum to integrate CBME, competencies must be developed and clearly specified how they will fit into a coherent and implementable curriculum structure. In this article, we describe existing practices some educational institutions have, including our experiences in the Office of CPD at the University of Ottawa, Canada, in designing a competency-based curriculum and provide 12 tips for those who begin their journey of organizing, developing, and implementing such curricula. We conclude that in order to translate a competency-based approach into CPD, educational programs will have to refine curricula across health professionals' education using curriculum mapping as an important tool of curriculum development and evaluation.

RESUMO

OBJECTIVES: A structured, reflection-based electronic portfolio program (ePortfolio), with novel faculty development initiative, involving 'shadow coaches', was shared with the newly formed Ottawa-Shanghai Joint School of Medicine (OSJSM). OSJSM is a partnership between Shanghai Jiao Tong University and the University of Ottawa. As the world's first Sino-Canadian Joint Medical School, OSJSM introduced North American undergraduate medical curriculum to China. 'Shadow coaching' involved trans-Pacific pairing of coaches, supplemented by local faculty development. FRAMEWORK: (a) Pre-implementation: The well-established online ePortfolio platform at the University of Ottawa was mirrored at OSJSM. University of Ottawa ePortfolio coaches were recruited to serve as shadow coaches to their OSJSM counterparts. Shadow coaches provided mentoring and resources while maintaining awareness of cross-cultural issues. Faculty development consisted of face-to-face faculty development in Shanghai, several online synchronous sessions, and familiarization of University of Ottawa coaches with the Chinese medical education system. (b) Description/Components: This intervention, introduced in 2016-2017, involved five University of Ottawa shadow coaches paired with five OSJSM ePortfolio coaches. Student reflection encourages open frank discussion which is a new paradigm for Chinese students and faculty. Shadow coaches were encouraged to challenge new OSJSM coaches to widely explore physician roles and competencies. RESULTS: Initial results indicate that the experience served to effectively develop OSJSM coaches' skills as evidenced by shadow coaches' review of anonymized OSJSM student reflective writing. CONCLUSIONS: Our project describes a novel tool using shadow coaching for faculty development for a cross-cultural partnership. Similar approaches can be utilized for culturally-sensitive long-distance faculty development.

RESUMO

PURPOSE: Assessing students' professionalism is a critical component of medical education. Nonetheless, faculty reluctance to report professionalism lapses remains a significant barrier to the effective identification, management, and remediation of such lapses. The authors gathered information from faculty who supervise medical students to better understand their perceived barriers to reporting. METHOD: In 2015-2016, data were collected using a group concept mapping methodology, which is an innovative, asynchronous, structured mixed-methods approach using qualitative and quantitative measures to identify themes characterizing faculty reluctance to report professionalism lapses. Participants from four U.S. and Canadian medical schools brainstormed, sorted, and rated statements about perceived barriers to reporting. Multidimensional scaling and hierarchical cluster analyses were used to analyze these data. RESULTS: Of 431 physicians invited, 184 con-tributed to the brainstorming task (42.7%), 48 completed the sorting task (11.1%), and 83 completed the rating task (19.3%). Participants identified six barriers or themes to reporting lapses. The themes "uncertainty about the process," "ambiguity about the 'facts,'" "effects on the learner," and "time constraints" were rated highest as perceived barriers. Demographic subgroup analysis by gender, years of experience supervising medical students, years since graduation, and practice discipline revealed no significant differences (P > .05). CONCLUSIONS: The decision to report medical students' professionalism lapses is more complex and nuanced than a binary choice to report or not. Faculty face challenges at the systems level and individual level. The themes identified in this study can be used for faculty development and to improve processes for reporting students' professionalism lapses.

RESUMO

When recombinant human (rh) thyroid-stimulating hormone (TSH) is administered to thyroid cancer survivors, an acute extra-thyroidal effect raises pro-inflammatory cytokines and activates platelets. Thymic stromal lymphopoietin (TSLP) is a cytokine recently implicated in platelet activation. Our aim was to measure platelet microparticle levels after rhTSH stimulation in vivo, and to investigate TSLP expression in TSH-stimulated human adipocytes in culture. Blood samples for total and platelet microparticle analysis were obtained from thyroid cancer survivors before (day 1) and after rhTSH administration (day 5). Adipocytes, differentiated from stromal preadipocytes isolated from adipose tissue from surgical patients, were stimulated with TSH. TSLP mRNA expression, protein expression, and protein release into the adipocyte medium were measured. The level of platelet microparticles in thyroid cancer patients rose 5-fold after rhTSH stimulation. TSH upregulated TSLP mRNA expression in adipocytes in culture through a pathway that was inhibited by 66% by H89, a protein kinase A inhibitor. TSLP protein expression rose in response to TSH, and TSH-stimulated TSLP release into the medium was completely blocked by dexamethasone. In conclusion, TSLP is a novel TSH-responsive adipokine. Future studies will be needed to address the potential role of adipocyte-derived TSLP and whether it is linked to TSH-dependent platelet activation.

RESUMO

RATIONALE AND OBJECTIVES: Thyroid nodules are common in the population, although the rate of malignancy is relatively low (5%-15%). The purpose of this study was to determine if introducing a modified standardized reporting format and management algorithm (Thyroid Imaging Reporting and Data System [TI-RADS]) affects radiologist reporting adherence, number of thyroid biopsies, and other measurable outcomes. MATERIALS AND METHODS: All thyroid biopsies performed over two 6-month periods were evaluated at a tertiary care hospital with Research Ethics Board approval. The first period was before implementation of TI-RADS and the second was several months after implementation of TI-RADS (using a modified version made through a multidisciplinary collaboration). The number of biopsies performed was determined in each of the two periods as well as the percent of positive malignancy, wait times, and rates of non-diagnostic/unsatisfactory and inconclusive biopsies, which included atypia of undetermined significance (AUS) and follicular lesion of undetermined significance (FLUS). RESULTS: The average number of biopsies performed prior to implementing modified Kwak's TI-RADS was 74 thyroid biopsies per month and the average number of diagnostic ultrasounds was 271. After the introduction of modified Kwak's TI-RADS, the average number of thyroid biopsies decreased to 60 per month (an 18.9% reduction, P < .05), and the number of diagnostic ultrasound increased to 287 per month (a 5.9% increase from 2016 to 2017). The average wait time for a thyroid biopsy decreased from 5 to 3 weeks (P < .05). There was a slight increase in the rate of positive malignancy results (from 15% to 18%), although it was not statistically significant. The rate of non-diagnostic/unsatisfactory and inconclusive results (including AUS and FLUS) remained unchanged (18% AUS/FLUS/15% non-diagnostic/unsatisfactory before and 17% AUS/FLUS/15% non-diagnostic/unsatisfactory after TI-RADS introduction, P > .05). CONCLUSIONS: Introduction of a multidisciplinary-approved standardized reporting system with evidence-based management recommendations led to no statistically significant change in the number of diagnostic ultrasounds but a statistically significant reduction in the number of monthly thyroid biopsies and associated reduction in wait times.

RESUMO

INTRODUCTION: Continuing professional development (CPD) offerings should address the educational needs of health care providers. Innovative programs, such as electronic consultations (eConsults), provide unique educational opportunities for practice-based needs assessment. The purpose of this study is to assess whether CPD offerings match the needs of physicians by coding and comparing session content to clinical questions asked through eConsults. METHODS: This study analyzes questions asked by primary care providers between July 2011 and January 2015 using a service that allows specialists to provide consultation over a secure web-based server. The content of these questions was compared with the CPD courses offered in the area in which these primary care providers are practicing over a similar period (2012-2014). The clinical questions were categorized by the content area. The percentage of questions asked about each content area was calculated for each of the 12 specialties consulted. CPD course offerings were categorized using the same list of content areas. Percentage of minutes dedicated to each content area was calculated for each specialty. The percentage of questions asked and the percentage of CPD course minutes for each content area were compared. RESULTS: There were numerous congruencies and discrepancies between the proportion of questions asked about a given content area and the CPD minutes dedicated to it. DISCUSSION: Traditional needs assessment may underestimate the need to address topics that are frequently the subject of eConsults. Planners should recognize eConsult questions as a valuable source of practice-associated challenges that can identify professional development needs of physicians.
