PURPOSE: Regular recreational moderate to vigorous physical activity (rMVPA) has been previously associated with a reduced risk of colorectal cancer (CRC), however, few studies have examined the association of rMVPA with colorectal polyps, the pre-malignant precursor lesions. The objective of this study was to examine the associations between physical activity and sitting time and polyps at the time of screening. METHODS: We conducted a cross-sectional study of 2496 individuals undergoing screening-related colonoscopy in Calgary, Alberta, Canada...

Campylobacter jejuni was longitudinally isolated from beef cattle housed in four confined feeding operations (CFOs) in southern Alberta over 18 months. All of the cattle were administered a variety of antimicrobial agents (AMAs) non-therapeutically and metaphylactically during their time in the CFOs. In total, 7966 C. jejuni isolates were recovered from cattle. More animals were colonized by the bacterium after >60 days in the CFO (i.e. interim) compared to individuals upon entry at the CFO (i.e. arrival)...

The developmental health of young children is highly influenced by the socioeconomic conditions in which they are raised. How to accurately measure these conditions is a point of debate in the current literature on child development, health, and social determinants. We have evaluated four existing indices of socioeconomic status (SES) to determine the most relevant for the analysis of early childhood development (ECD) in Canada. Following a literature review of published SES indices which used 2006 Canadian Census data, four indices were chosen based on their relevance to ECD and the number of citations in subsequent articles...

A sharp increase in the frequency of earthquakes near Fox Creek, Alberta, began in December 2013 in response to hydraulic fracturing. Using a hydraulic fracturing database, we explore relationships between injection parameters and seismicity response. We show that induced earthquakes are associated with completions that used larger injection volumes (104 to 105 cubic meters) and that seismic productivity scales linearly with injection volume. Injection pressure and rate have an insignificant association with seismic response...

We describe a novel technical approach to acute stroke illustrated by the case of a 41 year old male who presented with tandem right common carotid artery (CCA) and M1 occlusions. His NIHSS was 17 and Alberta stroke programe early CT score (ASPECTs) was 8. Thrombectomy initially proved challenging due to large volume CCA thrombus that repeatedly occluded the aspiration catheters. However, by inflating a balloon distally and pulling clot into the adjacent ECA, we were able to quickly restore distal contrast flow to the intracranial circulation and achieve Thrombolysis In Cerebral Infarction/Arterial Occlusive Lesion (TICI2C/AOL3) revascularization...

BACKGROUND: Cerebral venous thrombosis is a rare cause of stroke, with a number of well-defined risk factors. However, there exist few studies that describe trends in the prognosis of this disease over time. METHODS: A retrospective study was performed on patients diagnosed with cerebral venous thrombosis at the University of Alberta Hospital during two time periods: 1988-1998 (21 patients) and 1999-2009 (40 patients). Signs and symptoms, risk factors, imaging findings, etiologies, treatment modalities, and status at discharge were examined...

BACKGROUND: Many Canadian schools offer breakfast programs; however, students' engagement in these programs is low, while breakfast skipping is highly prevalent among youth. This study examined whether the availability of breakfast programs supports adolescents' regular breakfast eating, and identified characteristics of breakfast skippers who are not using these programs. METHODS: Data from 30,771 secondary school students from Ontario and Alberta, Canada, participating in Year 3 (2014-2015) of the COMPASS study were used for descriptive and logistic regression analyses...

Ensuring adequate vascular access in major trauma patients prior to decompensative physiological processes is crucial to patient outcomes. Most protocols suggest achieving two 18-gauge or larger intravenous lines immediately in patients with major trauma. We discuss a quality improvement approach to ensure that >90% of patients with major trauma (as defined by an injury severity score ≥12) at a level one trauma centre receive timely and adequate fluid access. Applying Donabedian principles for process improvement, we used the Alberta Trauma Registry to perform a 4-month chart audit on patients with major trauma at the University of Alberta Hospital...

BACKGROUND: Recently, the US Institute of Medicine has proposed that raising the minimum age for tobacco purchasing/sales to 21 years would likely lead to reductions in smoking behavior among young people. Surprisingly few studies, however, have assessed the potential impacts of minimum-age tobacco restrictions on youth smoking. OBJECTIVE: To estimate the impacts of Canadian minimum age for tobacco sales (MATS) laws on youth smoking behaviour. DESIGN: A regression-discontinuity design, using seven merged cycles of the Canadian Community Health Survey, 2000-2014...

Hastelloy X (HX) is a Ni-based superalloy which suffers from high crack susceptibility during the laser powder bed fusion (LPBF) process. In this work, the microstructure of as-built HX samples was rigorously investigated to understand the main mechanisms leading to crack formation. The microstructural features of as-built HX samples consisted of very fine dendrite architectures with dimensions typically less than 1 µm, coupled with the formation of sub-micrometric carbides, the largest ones were mainly distributed along the interdendritic regions and grain boundaries...

Hippoboscid flies (Diptera: Hippoboscidae) include species that are ectoparasites of birds in the Northern Hemisphere, but little is known regarding their taxonomy, parasites, avian host associations, or geographical distribution in North America. In late August of 2013 and 2014, we collected hippoboscid flies from live birds trapped in mist nets as part of a banding study in Cypress Hills Interprovincial Park in southeastern Alberta, Canada. A total of 113 birds comprising 9 species was examined in 2013. Of these, 18 individuals were infested with 1-3 Ornithomya anchineuria Speiser (n = 22 flies; prevalence = 15...

Factors affecting wildland-fire size distribution include weather, fuels, and fire suppression activities. We present a novel application of survival analysis to quantify the effects of these factors on a sample of sizes of lightning-caused fires from Alberta, Canada. Two events were observed for each fire: the size at initial assessment (by the first fire fighters to arrive at the scene) and the size at "being held" (a state when no further increase in size is expected). We developed a statistical classifier to try to predict cases where there will be a growth in fire size (i...

Compensation programs are used globally to increase tolerance for and help offset economic loss caused by large carnivores. Compensation program funding comes from a variety of sources, and in Wyoming and Idaho, USA and Alberta, Canada this includes revenue from hunting and fishing license sales. We review the patterns of livestock depredation and compensation costs of Alberta's predator-compensation program, and compare Alberta's program to compensation programs in neighboring Canadian and American jurisdictions...

Background: Community pharmacists are well positioned to identify patients with poorly controlled asthma and trained to optimize asthma therapy. Yet, over 90% of patients with asthma live with uncontrolled disease. We sought to understand the current state of asthma management in practice in Alberta and explore the potential use of the Chat, Check and Chart (CCC) model to enhance pharmacists' care for patients with asthma. Methods: An 18-question survey was used to examine pharmacists' monitoring of asthma control and prior use of the CCC tools...

Background: Oral anticoagulant therapy (OAC) to prevent atrial fibrillation (AF)-related strokes remains poorly used. Alternate strategies, such as community pharmacist prescribing of OAC, should be explored. Methods: Approximately 400 pharmacists, half with additional prescribing authority (APA), randomly selected from the Alberta College of Pharmacists, were invited to participate in an online survey over a 6-week period. The survey consisted of demographics, case scenarios assessing appropriateness of OAC (based on the 2014 Canadian Cardiovascular Society AF guidelines) and perceived barriers to prescribing...

An important element of highway design is ensuring that the available sight distance (ASD) on a highway meets driver needs. For instance, if the ASD at any point on a highway is less than the distance required to come to a complete stop after seeing a hazard (i.e. Stopping Sight Distance (SSD)), the driver will not be able to stop in time to avoid a collision. SSD is function of a number of variables which vary depending on the driver, the vehicle driven and surface conditions; examples of such variables include a driver's perception reaction time or PRT (i...
