This article presents the results of the development and implementation of a mentorship program, now in its sixth year, designed to support the professional development of teaching skills for faculty and contract instructors. The program is unique in that it is a combination of a variety of other approaches such as formal and informal mentoring as well as intra-departmental and inter-departmental mentoring. This model incorporates the effective elements of a mentor program as identified in the literature, while eschewing the traditional model of one-to-one mentoring between senior and junior colleagues. The findings to date, which include more support for teaching after participating in the project as well as an increase in the amount of faculty accessing a mentor, indicate that the program is achieving its intended goals and should continue. The authors provide recommendations and suggestions for the inclusion of a teaching mentorship program at other institutions within (or outside of) Canada.

To identify the potential for adverse effects of forest development on Mountain Goats (Oreamnos americanus), we documented the patterns of forest use by goats and the factors influencing goat habitat use. We used a combination of 15 very high frequency (VHF) and six global positioning system (GPS) radiocollars to document the distribution and movements of 21 (15 female, 6 male) goats from 1997 to 1999 in the mountains surrounding the Robson Valley in east-central British Columbia. Because canopy closure reduces the likelihood that a GPS receiver will obtain a location fix, we estimated that GPS collars underrepresented forest use by about 23%. Three goats used separate winter and summer ranges separated by 8-13 km, while most simply exhibited seasonal shifts in elevation. In winter, goats were more often at lower elevations, in commercial forest stands, on southerly aspects, and moved less each hour and over the course of the winter. Goat use declined in areas >500 m from escape terrain and goats were found lower in elevation from evening to dawn compared to daylight hours. Collared goats used high elevation licks, which were either within their home range, or in two cases, 6 and 14 km from their typical home range. We documented use of known mid-elevation mineral licks by three collared goats, but no use of known low elevation (valley bottom and lower slopes) mineral licks. Robson Valley goats appeared to be at relatively low risk from disturbances related to logging, because although forest use was documented during winter, it occurred primarily on high elevation, steep slopes where trees are currently of low commercial value, and goats made little use of low elevation mineral licks. We recommend that in this area a forested buffer of 500 m around cliffs be left to reduce the possibility of adverse effects on goats especially, on southerly aspects above 1300 m.

The Canada Lynx (Lynx canadensis) is the most common and widespread member of the cat family in Canada. Lynx are distributed throughout forested regions of Canada and Alaska and into portions of the northern contiguous United States, closely paralleling the range of its primary prey, the Snowshoe Hare (Lepus americanus). They are most common in the boreal, sub-boreal and western montane forests, preferring older regenerating forests (>20 years) and generally avoiding younger stands, and occupy roughly 95% of their former range in Canada. Lynx population size fluctuates 3-17 fold over an 8-11 year cycle, tracking the abundance of Snowshoe Hares with a 1-2 year lag. During increasing and high hare abundance, lynx have high reproductive output and high kit and adult survival. The decline phase is characterized by reproductive failure, increased natural mortality, and high rates of dispersal. Dispersal distances of over 1000 km have been recorded. During the cyclic low, kit recruitment essentially fails for 2-3 years, and is followed by several years of modest reproductive output. Reproductive parameters in southern lynx populations appear similar to those found during the cyclic low and early increase phase in more northern populations. Trapping is a significant source of mortality in some areas. Field studies have documented from 2-45 lynx/100 km2 at various times in the cycle and in various habitats. Although the amplitude of the cyclic fluctuations in lynx numbers may have decreased somewhat in recent decades, there is no evidence to suggest a significant decline in numbers in Canada. Lynx are managed as a furbearer in Canada, with harvest regulated primarily by seasons, quotas, and closures. The harvest over the past decade has declined concurrent with declining pelt prices, and is currently a fraction of historic levels. Lynx are fully protected in less than 2-3% of their range in Canada. There is no evidence to suggest that... [ABSTRACT FROM AUTHOR]

SUMMARY The red algal crust, ‘Petrocelis franciscana’ Setchell et Gardner [= tetrasporophytic phase of Mastocarpus papillatus (Agardh) Kützing] exists as discrete patches on boulders throughout the intertidal zone at Burrard Inlet in Vancouver (mainland British Columbia) and at Sooke, Vancouver Island (British Columbia). This study photographically quantifies monthly surface area of 60 individual crusts over 12- and 18-month periods, respectively, at the two sites. Conspicuous seasonal fluctuations in ‘Petrocelis’ abundance and relatively low survivorship of crusts sampled suggest that not all crusts are as static and as long-lived (> 25 years) as previously suggested. Herbivory, sloughing of senescing tissue and abiotic factors visibly reduce ‘Petrocelis’ abundance in fall and winter; regeneration of lost crust tissue and relatively rapid crust growth occur from spring to early fall.

Peripheral artery disease (PAD) is a burdensome disease. It is unclear whether PAD cohorts enrolled in contemporary randomized control trials (RCT) are representative of the real-world PAD populations in terms of their patient characteristics. We compared baseline patient characteristics and health status (as measured by the Peripheral Artery Questionnaire [PAQ]) between the randomized CLEVER study, and the real-world PORTRAIT registry. CLEVER was an RCT of PAD patients enrolled from 29 centers across the US and Canada comparing revascularization with stenting versus optimal medical therapy (OMT) and supervised exercise therapy (SET) plus OMT. PORTRAIT was a multicenter, prospective study of patients with new or worsening PAD symptoms across ten sites in the US. The final cohort consisted of 879 patients (n = 119 from CLEVER, n = 760 from PORTRAIT (24.5% black, 41.4% women). While CLEVER enrolled patients with aortoiliac disease, only 16.0% of the PORTRAIT cohort had isolated aortoiliac disease. Compared with CLEVER, patients from PORTRAIT were older (64.0 ± 9.5 versus 68.9 ± 9.5 yrs., p ≤0.001), had more severe disease as measured by the ankle brachial index (0.7 ± 0.2 versus 0.9 ± 0.2, p ≤0.001) and a higher prevalence of cardiovascular risk factors including hyperlipidemia and diabetes (all p values<0.05). Both cohorts had similar disease-specific health status as measured by the PAQ summary score (47.4 ± 21.9 versus 43.6 ± 18.4, p = 0.07). In this comparative study, real-world patients with PAD were older and sicker when compared to an RCT with similar indications. This gap may be bridged by improving enrollment of underrepresented high-risk patients in PAD trials testing strategies for PAD symptom relief. https://clinicaltrials.gov/ct2/show/NCT01419080?term=portrait&rank=1 NCT01419080.

Current heart transplantation (HT) guidelines support weight loss to achieve a body mass index (BMI) ≤35kg/m2 prior to listing; however, there are conflicting data on whether pre-transplant obesity is associated with worse outcomes post transplant. A more specific marker of human body composition, whole body fat mass (WBFM), derived from fat segmentation using abdominal computed tomography (abdCT), has been shown to predict outcomes in chronic illness. We sought to assess whether WBFM, whole body fat free mass (WBFFM), and BMI were predictive of 1-yr post-transplant outcomes. Adults who underwent HT from 2014-2019 at a single tertiary medical center with interpretable abdCT obtained within 3 months prior to HT were retrospectively assessed. Patients were excluded if abdCTs were unavailable, acquired >3 months from transplant date, or had poor image quality. Tissue characterization/fat and muscle segmentation were performed using Slice-O-Matic software v5.0 (TomoVision, Canada). WBFM and WBFFM were derived. Statistical analysis was performed with R statistical software (v4.1.1). A total of 69 pts were analyzed, of which 56 were male (81.2%), 39 Caucasian (56.5%), and 24 (34.8%) with pre-transplant diabetes mellitus (DM). Median BMI [IQR] was 29.2 kg/m2 [23.7,31.7], median WBFM [IQR] 27.9kg [22.6, 34.2], and median WBFFM [IQR] 51.9kg [46.5,57.9]. In univariate Poisson regression, BMI (p<.01) and WBFM (p=0.01) were predictive of index hospital length of stay (LOS). However, BMI, WBFM, and WBFFM were not predictive of composite of infection, rejection, graft failure, or death in the 1st year. In univariate logistic regression, BMI, WBFM, WBFFM were not predictive of rejection or graft failure. In multivariate Poisson regression adjusting for age, male sex, pre-transplant DM, and CKD history, BMI was only predictive of index LOS (IRR 1.02, p<0.01, CI 1.01, 1.03). Consistent with prior studies, BMI is not associated with worse 1-yr outcomes after HT. While quantitatively derived WBFM and BMI are predictive of index LOS, we found that overall BMI, WBFM, and WBFFM are not predictive of infection, rejection, graft failure, or death within 1 year. Limitations include small sample size and retrospective nature. Future studies should aim to include larger sample size and to prospectively assess long-term outcomes. [ABSTRACT FROM AUTHOR]

Cannabis is the most commonly used psychoactive substance in Canada. The prevalence of cannabis use both during pregnancy and in the postpartum period has been estimated at 5% of the population. Women who use the drug during lactation place their infants at risk of exposure to cannabis and its metabolites in breast milk. This article provides a systematic review of infant outcomes associated with cannabis use by women during lactation followed by clinical recommendations. A review of the literature was conducted using Medline, Embase, and PsychInfo from their start to July 2018. Inclusion criteria consisted of articles addressing the impact of postpartum cannabis use by lactating women and providing developmental outcomes for infants. Two articles met these criteria and were included in our systematic review. Results indicate conflicting outcomes regarding the risk of exposure to cannabis in breast milk. Women should be advised to abstain from cannabis use during lactation or reduce consumption if abstinence is not possible. Furthermore, women should be advised to avoid breastfeeding within 1 hour of inhaled use to reduce exposure to highest concentration of cannabis in breast milk. Despite some evidence regarding health risks of post-natal exposure to cannabis, further research is needed to determine its impact on infant neurodevelopmental outcomes beyond the first year of life., (Copyright © 2019 The Society of Obstetricians and Gynaecologists of Canada/La Société des obstétriciens et gynécologues du Canada.

Purpose: Prospective radiology fellows often rely on the internet to obtain information with regard to the application process for and the unique qualities of different fellowship programs. The aim of this study was to analyze the content of websites of the United States' and Canadian cardiothoracic radiology fellowships., Methods: All active Cardiothoracic Radiology fellowship websites as of July 2019 were evaluated and compared using 25 criteria in the following domains: Application, Recruitment, Clinical Training, Education/Research, and Incentives. Program website information availability was compared by geographic region., Results: There were 60 active cardiothoracic radiology fellowships, and 59 of these fellowships had a dedicated fellowship website. Websites, on average, had 9.3 of the 25 criteria (37.2%). The mean number of schools that satisfied the criterion in the "Incentives" domain ([7.75/59] 10.5%±2.8%) was significantly lower than that for the "Application Process" domain ([40.50/59]; 68.7%±40.6%) (P=0.01). There was no significant difference in the information content of programs in different geographic regions (P=0.246)., Conclusion: Most cardiothoracic radiology fellowship websites were lacking content relevant to prospective fellows. Provision of more relevant and easily accessible online content may support programs to better inform and recruit residents and to promote the specialty of cardiothoracic radiology.

Background and Objectives: To provide a contemporary estimate of the economic burden of atherothrombosis in Canada, annual cardiovascular-related hospitalizations, medication use and associated costs across the entire spectrum of atherothrombotic disease were examined., Methods: The REduction of Atherothrombosis for Continued Health (REACH) registry enrolled 1964 Canadian outpatients with coronary artery disease, cerebrovascular disease or peripheral arterial disease (PAD), or three or more cardiovascular risk factors. Baseline data on cardiovascular risk factors and associated medication use, and one-year follow-up data on cardiovascular events, hospitalizations, procedures and medication use were collected. Annual hospitalization and medication costs (Canadian dollars) were derived and compared among patients according to the presence of established atherothrombotic disease at baseline, specific arterial beds affected and the number of affected arterial beds., Results: Average annualized medication costs were $1,683, $1,523 and $1,776 for patients with zero, one, and two or three symptomatic arterial beds, respectively. Average annual hospitalization costs increased significantly with the number of beds affected ($380, $1,403 and $3,465, respectively; P<0.0001 for overall linear trend). Mean hospitalization costs for patients with any coronary artery disease, any cerebrovascular disease and any PAD were $1,743, $1,823 and $4,677, respectively. After adjusting for other clinical factors, PAD at baseline was independently associated with a significant increase in hospitalization costs., Conclusion: Costs associated with vascular-related hospitalizations and interventions for Canadian patients increased with the number of affected arterial beds, and were particularly high for patients with PAD and⁄or polyvascular disease. These contemporary data provide insight into the economic burden associated with atherothrombotic disease in Canada, and highlight the need for increased preventive strategies to lessen the burden for patients and society.

Collaboration between hospitals and community organisations has been promoted over the past 20 years by various levels of government, hospital associations, health promotion advocates, and others at the state/province, national and international levels as a way to improve the 'efficiency of the system', reduce duplication, enhance effectiveness and service coordination, improve continuity of care, and enhance community capacity to address complex issues. Nevertheless, and despite a growing literature on interagency collaboration, systematic documentation and empirical analysis of hospital-community collaboration (HCC) is almost completely lacking in the literature, particularly as regards collaborations that address the determinants of health beyond the hospital walls. In this paper, we describe the methodology and key findings from a research study of HCC. The Hospital Involvement in Community Action (HICA) study undertook detailed qualitative case studies (in four urban, suburban, rural and northern locations) and a telephone survey (of 139 community organisations in a large urban centre) in order to learn about the range of collaborations and working relationships that exist between hospitals and community agencies in the province of Ontario (Canada), and the factors that influenced (enabled and/or hindered) HCC. Particular attention was paid to barriers and enablers at three nested levels of context (policy, hospital and community) and, drawing primarily on the qualitative case studies, it is this aspect that is the focus of this paper. That such collaborations continue to be widespread despite a generally unfavourable policy environment and hospital institutional culture that poses significant barriers, suggests that the extent to which HCC flourishes (or exists at all) crucially depends on the presence and ongoing enthusiasm/commitment of one or more 'champions' within the hospital, and the commitment of both parties to overcome the marked cultural differences between hospital and community. We conclude with a discussion of implications for policy and practice.
