Implementation of Competency-Based Medical Education in a Canadian Medical Oncology Training Program: a First Year Retrospective Review.

As part of a university-wide initiative, competency-based medical education (CBME) was implemented in the Medical Oncology training program at Queen's University in July 2017. Stages, entrustable professional activities (EPAs), and required training experiences established by the Royal College of Physicians and Surgeons of Canada (RCPSC) national subspecialty committee were adopted. Entrada (Elentra), the electronic portfolio developed at Queen's University, was used for assessment collection. Between July 2017 and December 2018, participating faculty members completed 157 assessments. Eighty-nine percent were EPA assessments with a median of 16 assessments per faculty member (range 1-40). Ninety-five percent of assessments included written "Comments" or "Next steps" with 56% of all assessments including specific or actionable feedback. Discussions between the program director, residents, program administrator, CBME education consultant, and CBME lead led to the identification of 9 lessons learned during implementation. These centered on (1) faculty and resident development and engagement; (2) sharing the work of CBME; (3) collaboration and communication; (4) global assessment; (5) assessment plan challenges; (6) burden of CBME; (7) limitations of e-portfolio; (8) importance of early tracking of resident progress; and (9) culture change. This article describes the experience of the authors and considers strategies that may be helpful to programs implementing CBME in their teaching and learning environment.

Is Access to Care Associated With Stage at Presentation and Survival for Melanoma Patients?

BACKGROUND: Melanoma incidence increases with socioeconomic status but the effect of rurality and access to primary care or dermatology on patient outcomes is unclear. OBJECTIVES: The objectives of this study were to determine whether access to care, rurality, or socioeconomic status are associated with melanoma stage at presentation and prognosis. METHODS: Linked administrative databases from Ontario, Canada, were retrospectively analyzed to identify a population-based cohort of patients diagnosed with melanoma between 2004 and 2012. Rurality was assessed using the rural index of Ontario (RIO) score, and the number of visits to dermatology and primary care was used to evaluate access to care. RESULTS: We identified 18 776 melanoma patients, of whom 9591 had completed pathological staging. Patients with higher RIO scores, living further from a cancer center or in a rural community, were less likely to see a dermatologist in the year prior to diagnosis (P < .001 for all). Patients seen by a dermatologist within 365 days prior to diagnosis were less likely to present with stage III or IV disease (odds ratio 0.63, P < .001) and had improved overall survival (hazard ratio [HR] for death 0.77, P < .001). There was a nonlinear association between number of family physician visits and melanoma prognosis, with patients who had 3 to 5 visits per year having the best overall survival (HR 0.88, P = .003). CONCLUSION: Our findings strengthen the known association between access to dermatology and melanoma outcomes by linking individual patients' prediagnosis access to care to pathological stage at diagnosis and overall survival.

Niacin deficiency delays DNA excision repair and increases spontaneous and nitrosourea-induced chromosomal instability in rat bone marrow.

We have shown that niacin deficiency impairs poly(ADP-ribose) formation and enhances sister chromatid exchanges and micronuclei formation in rat bone marrow. We designed the current study to investigate the effects of niacin deficiency on the kinetics of DNA repair following ethylation, and the accumulation of double strand breaks, micronuclei (MN) and chromosomal aberrations (CA). Weanling male Long-Evans rats were fed niacin deficient (ND), or pair fed (PF) control diets for 3 weeks. We examined repair kinetics by comet assay in the 36h following a single dose of ethylnitrosourea (ENU) (30mg/kg bw). There was no effect of ND on mean tail moment (MTM) before ENU treatment, or on the development of strand breaks between 0 and 8h after ENU. Repair kinetics between 12 and 30h were significantly delayed by ND, with a doubling of area under the MTM curve during this period. O(6)-ethylation of guanine peaked by 1.5h, was largely repaired by 15h, and was also delayed in bone marrow cells from ND rats. ND significantly enhanced double strand break accumulation at 24h after ENU. ND alone increased chromosome and chromatid breaks (four- and two-fold). ND alone caused a large increase in MN, and this was amplified by ENU treatment. While repair kinetics suggest that ND may be acting by creating catalytically inactive PARP molecules with a dominant-negative effect on repair processes, the effect of ND alone on O(6)-ethylation, MN and CA, in the absence of altered comet results, suggests additional mechanisms are also leading to chromosomal instability. These data support the idea that the bone marrow cells of niacin deficient cancer patients may be more sensitive to the side effects of genotoxic chemotherapy, resulting in acute bone marrow suppression and chronic development of secondary leukemias.
