Physical ocean circulation features, especially the Gaspé Current (GC) intrusion, influence the transport and aggregation of whale prey, thereby influencing the whale foraging habitat in the Gulf of St. Lawrence (GSL), Canada. We employ satellite altimetry-derived sea level anomaly (SLA) indices to monitor interannual variations in the intensity of the GC in the North Atlantic Right Whale (Eubalaena glacialis; NARW) habitat in the GSL. Measurements of surface slope and volume transport are taken from the SLA profiles along a repeating ground track of the Jason-2/3 satellites. These are employed as complementary proxies in characterizations of physical processes in the GSL. The relationship between altimetric indices and indices of zooplankton abundance are explored in the southern GSL. Results demonstrate that an altimetric index estimated from surface slope (Index s l o p e − h a l f ) is correlated with river discharge of the St. Lawrence River and can be utilized to infer variations in GC intensities. Time series of the altimetric indices during 2009–2021 are found to exhibit interannual and seasonal environmental variability, which influence transport into the southern GSL. As captured by the altimetric indices, these features of the surface ocean circulation can be linked to zooplankton variations in the Shediac Valley, where NARWs are frequently observed. Therefore, in linking physical drivers of ocean dynamics to the NARW foraging habitat, variations in these indices can also potentially help describe some features of the distribution patterns of NARW sightings in this area.

Purpose: The purpose of this study was to quantify the urine concentration of non-metabolized cyclophosphamide (CP), a commonly administered antineoplastic drug, among potentially exposed Canadian healthcare workers and to identify factors associated with the drug concentration levels. Methods: Participants were asked to provide two sets of 24-h urine samples (at two different sampling events), and the level of CP was quantified using high-performance liquid chromatography-tandem mass spectrometry. In addition to demographic information, participants were surveyed regarding their frequency of handling of antineoplastic drugs, safe drug handling training, and known contact with CP on their work shift. Descriptive and inferential statistical analyses were performed. A backward stepwise linear mixed effect model was conducted to identify the factors associated with urine concentration levels. Results: We collected 201 urine samples, and 55 % ( n = 111) had levels greater than the LOD of 0.05 ng/mL. The mean urinary CP concentration was 0.156 ng/mL, the geometric mean was 0.067 ng/mL, the geometric standard deviation was 3.18, the 75th percentile was 0.129 ng/mL, and the range was

Objective: To understand predictors of Canadian physicians' prevention counseling practices., Methods: A national mailed survey of a random sample of Canadian physicians conducted November 2007-May 2008., Results: Primary care physicians (n=3213) responded to the survey (41% response rate); those with better personal health habits, female physicians, and physicians aged 45-64 years old were more likely to report "usually/always" counseling patients than did others, but there were no significant differences by province, origin of one's MD degree, or practice location. There was a clear and consistent relationship between personal and clinical prevention practices: non-smokers were significantly more likely to report counseling patients on smoking cessation; those who drank alcohol less frequently, drank lower quantities or binged less often were more likely to counsel on alcohol; those exercising more to counsel patients more about exercise; those eating more fruits and vegetables to counsel patients more often about nutrition; and those with lower weight were more likely to counsel about nutrition, weight or exercise. Physicians who strongly agreed or agreed that "they will perform better counseling if they have healthy habits" averaged higher rates of counseling (p < 0.001)., Conclusions: Personal characteristics of Canadian physicians help predict prevention counseling. These data suggest that by encouraging physicians to be healthy, we can improve healthy habits among their patients--an innovative, beneficent, evidence-based approach to encouraging physicians to counsel patients about prevention.
