AIM: To examine the extent to which the theory of planned behavior (TPB) predicts academic clinicians' intent to treat pediatric obesity. METHODS: A multi-disciplinary panel iteratively devised a Likert scale survey based on the constructs of the TPB applied to a set of pediatric obesity themes. A cross-sectional electronic survey was then administered to academic clinicians at tertiary care centers across Canada from January to April 2012. Descriptive statistics were used to summarize demographic and item agreement data...

BACKGROUND: Our aim was to explore the relationships among perceived stress, intestinal inflammation, and inflammatory bowel disease (IBD) symptoms over time. METHODS: Participants were recruited from a population-based registry of persons with IBD and assessed at months 0, 3, and 6. Key dependent measures were the Manitoba IBD Index (symptom activity), Cohen's Perceived Stress Scale, and fecal calprotectin in stool (intestinal inflammation). RESULTS: Complete data were available for 417 participants at months 0; 369 provided follow-up data...

INTRODUCTION: Antitumor necrosis factor (anti-TNF) medications are known to be highly efficacious in persons with moderate-to-severe inflammatory bowel disease (IBD). There is a paucity of data from population-based sources to elucidate persistence with these medications in the general population of IBD. Discontinuation of anti-TNF therapy is a marker of lack of effectiveness, intolerance, and patient/physician practice preferences. METHODS: We identified all persons with IBD in Manitoba who were dispensed infliximab (IFX) and adalimumab (ADA) between 2001 and 2014...

BACKGROUND: Hospital discharge databases are used to study the epidemiology of Clostridium difficile infections (CDI) among hospitalized patients with inflammatory bowel disease (IBD). CDI in IBD is increasingly important and accurately estimating its occurrence is critical in understanding its comorbidity. There are limited data on the reliability of the International Classification of Diseases 10th revision (ICD-10) (now widely used in North America) CDI code in determining occurrence of CDI among hospitalized patients...

BACKGROUND: The impact of Chlamydia trachomatis (chlamydia) control on the incidence of pelvic inflammatory disease (PID) is theoretically limited by the proportion of PID caused by chlamydia. We estimate the population excess fraction (PEF) of treated chlamydia infection on PID at 12-months in settings with widespread chlamydia control (testing and treatment) and compare this to the estimated PEF of untreated chlamydia. METHODS: We used two large retrospective population-based cohorts of women of reproductive age from settings with widespread chlamydia control to calculate the PEF of treated chlamydia on PID at 12-months...

BACKGROUND: We aimed to determine whether maternal antenatal or perinatal infections (and thereby use of antibiotics) increase the risk of developing inflammatory bowel disease (IBD) in their offspring. METHODS: The University of Manitoba IBD Epidemiology Database contains records of all Manitobans diagnosed with IBD from 1984 to 2010. Each individual with IBD is matched to 10 controls. Subjects' medical system contacts are identified using a unique deidentified personal health identification number...

A sampling trip to Central Gold Mine, Nopiming Provincial Park, Canada, was taken in September 2011. Abundance, distribution, and physiology of aerobic anoxygenic phototrophs (AAP) from 4 locations were studied. Enumeration revealed 14.6% of culturable microbes were AAP. Five strains (NM4.16, NM4.18, C4, C9, C11) were chosen for analysis. All grow best on complex media without vitamin requirements and with an optimal pH 7.0-8.0, with strain C4 preferring pH 6.0. Strain NM4.18 tolerates the highest pH 11.0. Optimal temperature for all is 28 °C (range of 2-37 °C except NM4...

BACKGROUND: Though pharmacy claims data are commonly used to study medication adherence, there remains no standard operational definition for adherence especially for patients on multiple medications. Even when studies use the same terminology, the actual methods of calculating adherence can differ drastically. It is unclear whether the use of different definitions results in different conclusions regarding adherence and associated outcomes. The objective of our study was to compare adherence rates and associations with mortality using different operational definitions of adherence, and using various methods of handling concurrent medication use...

In this paper, our aim is to analyze geographical and temporal variability of disease incidence when spatio-temporal count data have excess zeros. To that end, we consider random effects in zero-inflated Poisson models to investigate geographical and temporal patterns of disease incidence. Spatio-temporal models that employ conditionally autoregressive smoothing across the spatial dimension and B-spline smoothing over the temporal dimension are proposed. The analysis of these complex models is computationally difficult from the frequentist perspective...

Lyme disease is emerging in eastern and central Canada, and most cases are diagnosed using the two-tier serological test (Enzyme Immuno Assay [EIA] followed by Western blot [WB]). Simplification of this algorithm would be advantageous unless it impacts test performance. In this study, accuracy of individual proteins of the IgG WB algorithm in predicting the overall test result in samples from Canadians was assessed. Because Borrelia burgdorferi strains vary geographically in Canada, geographic variations in serological responses were also explored...

There are few beneficial management practices (BMPs) with demonstrated efficacy in snowmelt-dominated regions. Small reservoirs are a BMP that can help mitigate flooding and reduce sediment transport, while reducing export of dissolved nutrients. To understand controls on nitrate removal and assess how this ecosystem service can be optimized, denitrification activity was measured in reservoirs and stream pools of the Tobacco Creek Model Watershed (Manitoba, Canada) via the chloramphenicol-amended acetylene block technique...

Dietary cholesterol and plant sterols differentially modulate cholesterol kinetics and circulating cholesterol. Understanding how healthy individuals with their inherent variabilities in cholesterol trafficking respond to such dietary sterols will aid in improving strategies for effective cholesterol lowering and alleviation of CVD risk. The objectives of this study were to assess plasma lipid responsiveness to dietary cholesterol v. plant sterol consumption, and to determine the response in rates of cholesterol absorption and synthesis to each sterol using stable isotope approaches in healthy individuals...

BACKGROUND: Lingonberry (Vaccinium vitis-idaea L.) contains high levels of anthocyanins which are bioavailable in the kidney and may be protective against ischemia-reperfusion (IR)-induced acute kidney injury. This study investigated the effect of lingonberry juice on IR-induced stress-activated signaling pathway and inflammatory response in the kidney. RESULTS: Sprague-Dawley rats subjected to kidney IR had significantly impaired kidney function, with increased activation of the JNK signaling pathway and increased inflammatory response, measured using a multiplex panel containing an extensive array of inflammatory biomarkers...

BACKGROUND: The data about whether patients with a prior urothelial cancer (uca) are at increased risk of colorectal cancer (crc) are conflicting. We used a competing risks analysis to determine the risk of crc after uca. METHODS: Historical cohorts were assembled by record linkage of Manitoba Cancer Registry and Manitoba Health databases. The incidence of crc for individuals with uca as their first cancer between 1987 and 2009 was compared with the incidence for randomly selected age-and sex-matched individuals without a cancer diagnosis at the index date (uca diagnosis date)...
