Training the next generation of Canadian Clinician-Scientists: charting a path to success

Clinician-scientists are physicians with training in both clinical medicine and research that enables them to occupy a unique niche as specialists in basic and translational biomedical research. While there is widespread acknowledgement of the importance of clinician-scientists in today’s landscape of evidence-based medical practice, training of clinician-scientists in Canada has been on the decline, with fewer opportunities to obtain funding. With the increasing length of training and lower financial compensation, fewer medical graduates are choosing to pursue such a career. MD-PhD programs, in which trainees receive both medical and research training, have the potential to be an important tool in training the next generation of clinician-scientists; however, MD-PhD trainees in Canada face barriers that include an increase in medical school tuition and a decrease in the amount of financial support. We examined the available data on MD-PhD training in Canada and identified a lack of oversight, a lack of funding and poor mentorship as barriers experienced by MD-PhD trainees. Specific recommendations are provided to begin the process of addressing these challenges, starting with the establishment of an overseeing national body that would track long-term outcome data for MD-PhD trainees. This national body could then function to implement best practices from individual programs across the country and to provide further mentorship and support for early-career physician-scientists. MD-PhD programs have the potential to address Canada’s growing shortage of clinician-scientists, and strengthening MD-PhD programs will help to effect positive change

Pituitary apoplexy: results of surgical and conservative management clinical series and review of the literature

Pituitary apoplexy is associated with visual, cranial nerve, and endocrine dysfunction. In this article, the results of surgical and conservative management of pituitary apoplexy in a single center are evaluated and a review of the literature is presented. A retrospective analysis was made of patients with pituitary apoplexy who underwent surgery or conservative management at our center between January 2007 and June 2017. Surgery was typically selected for patients who presented with acute deterioration of visual status and/or level of consciousness. Patients with no visual field deficit and those who had medical contraindications to undergo a surgical procedure because of previous comorbidities typically had conservative treatment. Baseline characteristics and clinical and radiologic outcomes were reviewed. A review of the literature (1990-2018) was performed according to PRISMA guidelines. Studies comparing the results of conservative and surgical management were identified. Visual, cranial nerve, and endocrine outcomes and tumor recurrence were analyzed. Forty-nine patients (73.1%) were managed surgically and 18 (26.9%) conservatively. After careful case selection, patients underwent surgical or conservative treatment. Patients who underwent conservative treatment had fewer visual deficits. At diagnosis, visual deficit (38.8% vs. 75.5%; P = 0.008) and cranial nerve palsy (27.7% vs. 51%; P = 0.058) were less common in the conservative group. Conservative and surgical treatments had similar visual and cranial nerve improvement rates (75% vs. 58.3%, P = 0.63 and 75% vs. 692%, P = 1.0, respectively). In the conservative group, tumor shrinkage was observed in 76.4% of cases. The systematic review retrieved 11 studies. No significant difference between conservative and surgical treatment for clinical outcomes (visual field recovery, odds ratio [OR], 1.45; 95% confidence interval [CI], 0.72-2.92; cranial nerve recovery, OR, 2.30; 95% CI, 0.93-5.65; and hypopituitarism, OR, 1.05; 95% CI, 0.64-1.74) or tumor recurrence (OR, 0.68; 95% CI, 0.20-2.34) was observed. A tailored approach to pituitary apoplexy, one that does not include an absolute need for surgery, is appropriate. Conservative management is appropriate in selected patients presenting without visual deficits.130E988E99
