BACKGROUND: Evidence for an association between transportation noise and cardiovascular disease has increased; however, few studies have examined metabolic outcomes such as diabetes or accounted for environmental coexposures such as air pollution, greenness, or walkability. OBJECTIVES: Because diabetes prevalence is increasing and may be on the causal pathway between noise and cardiovascular disease, we examined the influence of long-term residential transportation noise exposure and traffic-related air pollution on the incidence of diabetes using a population-based cohort in British Columbia, Canada...

BACKGROUND: Medullary thyroid carcinoma (MTC) accounts for 1-2% of all thyroid cancers. The clinical course of metastatic disease can be indolent. Our aim was to characterize the natural history of disease to evaluate the true proportion of patients who would be eligible for the currently available systemic therapies. METHODS: The British Columbia Cancer Agency (BCCA) provides cancer care to a population of 4.6 million. A retrospective chart review was conducted of all patients with MTC referred to the BCCA from 1991 to 2013...

Four Burkholderia pseudomallei-like isolates of human clinical origin were examined by a polyphasic taxonomic approach that included comparative whole genome analyses. The results demonstrated that these isolates represent a rare and unusual, novel Burkholderia species for which we propose the name B. singularis. The type strain is LMG 28154(T) (=CCUG 65685(T)). Its genome sequence has an average mol% G+C content of 64.34%, which is considerably lower than that of other Burkholderia species. The reduced G+C content of strain LMG 28154(T) was characterized by a genome wide AT bias that was not due to reduced GC-biased gene conversion or reductive genome evolution, but might have been caused by an altered DNA base excision repair pathway...

The hyporheic zone (HZ) is the active ecotone between the surface stream and groundwater, where exchanges of nutrients and organic carbon have been shown to stimulate microbial activity and transformations of carbon and nitrogen. To examine the relationship between sediment texture, biogeochemistry, and biological activity in the Columbia River HZ, the grain size distributions for sediment samples were characterized to define geological facies, and the relationships among physical properties of the facies, physicochemical attributes of the local environment, and the structure and activity of associated microbial communities were examined...

On rare occasions, small cream-coloured cysts have been observed in the heart and pericardial cavity of Pacific oysters Crassostrea gigas from British Columbia, Canada. Histopathology revealed the presence of large colonies of bacteria (up to 800 µm in diameter) causing significant host response and hypertrophy of the heart epithelium. The causative bacteria were characterized as follows: Gram-negative, coccoid to small rod-shaped, typically <1.5 µm in size, cell walls highly endowed with surface fimbriae and division via binary fission...

BACKGROUND: In Canada, the number of women sentenced to prison has almost doubled since 1995. In British Columbia, the rate of reincarceration is 70% within 2 years. Our aim was to identify factors associated with recidivism among women in British Columbia. METHODS: We prospectively followed women after discharge from provincial corrections centres in British Columbia. We defined recidivism as participation in criminal activity disclosed by participants during the year following release...

OBJECTIVES: Cross-sectional and longitudinal evidence from largely non-Hispanic White cohorts suggests that positive psychosocial factors, particularly self-efficacy and social support, may protect against late-life cognitive decline. Identifying potentially protective factors in racial/ethnic minority elders is of high importance due to their increased risk of Alzheimer's disease. The overall goal of this study was to characterize cross-sectional associations between positive psychosocial factors and cognitive domains among Black, Hispanic, and White older adults...

Achieving viral suppression among HIV-positive persons is a critical component of HIV treatment and prevention, because it leads to improved health outcomes for the individual and reduced risk of HIV transmission. There is wide variation in viral suppression across jurisdictions, races/ethnicities, age groups, and transmission risk groups. This analysis uses HIV surveillance data to examine rates of viral suppression among people living with diagnosed HIV (PLWDH) in 38 jurisdictions with complete lab reporting...

The utility of empirical combination antimicrobial therapy for gram-negative bloodstream infections (BSI) remains unclear. This retrospective, quasi-experimental matched cohort study examined the impact of empirical combination therapy on mortality in patients with gram-negative BSI. Hospitalized adults with gram-negative BSI from 1 January 2010 to 31 December 2013 at Palmetto Health Hospitals in Columbia, SC, USA were identified. Patients receiving combination or beta-lactam monotherapy therapy were matched 1:1 based on age, sex and Bloodstream Infection Mortality Risk Score (BSIMRS)...

BACKGROUND: During low temperature exposure, temperate plant species increase their freezing tolerance in a process termed cold acclimation. This is accompanied by dampened oscillations of circadian clock genes and disrupted oscillations of output genes and metabolites. During deacclimation in response to warm temperatures, cold acclimated plants lose freezing tolerance and resume growth and development. While considerable effort has been directed toward understanding the molecular and metabolic basis of cold acclimation, much less information is available about the regulation of deacclimation...

miRNAs are essential regulators of cell identity, yet their role in early embryo development in plants remains largely unexplored. To determine the earliest stage at which miRNAs act to promote pattern formation in embryogenesis, we examined a series of mutant alleles in the Arabidopsis thaliana miRNA biogenesis enzymes DICER-LIKE 1 (DCL1), SERRATE (SE), and HYPONASTIC LEAVES 1 (HYL1). Cellular and patterning defects were observed in dcl1, se and hyl1 embryos from the zygote through the globular stage of embryogenesis...

PROBLEM: Chronic diseases and conditions (e.g., heart diseases, stroke, arthritis, and diabetes) are the leading causes of morbidity and mortality in the United States. These conditions are costly to the U.S. economy, yet they are often preventable or controllable. Behavioral risk factors (e.g., excessive alcohol consumption, tobacco use, poor diet, frequent mental distress, and insufficient sleep) are linked to the leading causes of morbidity and mortality. Adopting positive health behaviors (e...

Mario Brondani, Syed H Ahmad
In Canada, about 1% of all emergency room (ER) visits in a given year are made by patients with a primary diagnosis of a non-traumatic, non-urgent and yet preventable condition, such as tooth decay. This percentage is typically dismissed as irrelevant. Using 2013-2014 British Columbia data on ER use from the Canadian Institute for Health Information, however, we argue that the 1% figure (and its associated cost) has to be considered beyond its percentage value. In 2013-2014 alone, 12 357 non-traumatic dental visits were made to ERs in BC representing 1% of the total number of ER visits at a cost of $154...
