AIM: Secondary femur fracture subsequent to treatment of trochanteric fractures with cephalomedullary nailing (i.e., a periprosthetic fracture related to the cephalomedullary nail) is a rare but very severe complication. As such, the aim of this study was to assess the impact of revision surgery and general state of health on mortality and functional outcomes in patients suffering femur fractures following treatment with cephalomedullary nails. MATERIALS AND METHODS: Between 2000 and 2015, 3549 patients presenting with OTA/AO 31A1-3 femur fractures were admitted to our department and subsequently treated with either a Gamma(®) Nail or PFNA(®)...

Understanding how local land use and land cover (LULC) shapes intra-urban concentrations of atmospheric pollutants-and thus human health-is a key component in designing healthier cities. Here, NO₂ is modeled based on spatially dense summer and winter NO₂ observations in Portland-Hillsboro-Vancouver (USA), and the spatial variation of NO₂ with LULC investigated using random forest, an ensemble data learning technique. The NO2 random forest model, together with BenMAP, is further used to develop a better understanding of the relationship among LULC, ambient NO₂ and respiratory health...

On the morning of April 9, 2015, citizens in Vancouver (British Columbia, Canada) awoke to the sight and smell of oil on the shores of popular downtown beaches. Because the oil also had spread over the shallow seawater intakes for the Vancouver Aquarium, a preliminary screening of samples was performed as a prompt, first response to assess the risks to the Aquarium collection and guide the emergency operational response. A subsequent, more detailed examination for the presence of spilled oil in sediment, biota and water samples from the Vancouver Harbour region was then conducted based on the analysis of a large suite of alkanes, petroleum biomarkers, parent polycyclic aromatic hydrocarbons (PAHs) and alkyl PAH isomers...

INTRODUCTION: Periprosthetic fractures are difficult to manage. Plating technique has been considered a reliable form of management of periprosthetic fractures with a well-fixed stem, but a dependable and stable method of plate fixation to the bone is lacking. This study reports the clinical results using a locking attachment plate (LAP) instead of cable fixation to fix locking plates to a periprosthetic femoral shaft fracture. MATERIALS AND METHODS: Nineteen patients with periprosthetic femoral shaft fractures around well-fixed stemmed implants were studied between August 2012 and December 2014...

Constructions of normative sexuality shape the sexual scripts that women are permitted to adopt and the manner in which such sexuality can be expressed. We explored experiences and constructions of premarital sexuality among migrant and refugee women recently resettled in Sydney, Australia, and Vancouver, Canada. A total of 78 semistructured individual interviews and 15 focus groups composed of 82 participants were undertaken with women who had migrated from Afghanistan, Iraq, Somalia, South Sudan, Sudan, Sri Lanka, and South America...

BACKGROUND: There is a lack of rigorous research investigating the factors that influence scar outcome in children. Improved clinical decision-making to reduce the health burden due to post-burn scarring in children will be guided by evidence on risk factors and risk stratification. This study aimed to examine the association between selected patient, injury and clinical factors and the development of raised scar after burn injury. Novel patient factors were investigated including selected immunological co-morbidities (asthma, eczema and diabetes type 1 and type 2) and skin pigmentation (Fitzpatrick skin type)...

Joane Y Tang, Tony K L Kiang, Mary H H Ensom
BACKGROUND: Coadministration of lorazepam and valproic acid is identified by tertiary references as causing a major drug interaction that requires therapy modification and dosage adjustments. The proposed mechanism involves inhibition of lorazepam glucuronidation via direct inhibition of uridine 5'-diphosphate-glucuronosyltransferase enzymes by valproic acid. However, the clinical significance of this interaction is unclear. OBJECTIVES: To identify site-specific practices and assess clinical responses to the interaction between valproic acid and lorazepam...

BACKGROUND: Evidence suggests emergency department (ED) overcrowding is associated with poor health outcomes. Children comprise 20-25% of general ED visits, yet few studies have examined the differential impact of ED overcrowding on pediatric and adult populations. OBJECTIVE: The primary objective of this study was to compare flow measures, such as wait time to see a physician, length of stay (LOS), and rate of patients leaving without being seen by a physician (LWBS) between adults and children in British Columbia and Ontario, clustered by province, and then stratified by acuity level during the study period...

INTRODUCTION: Public bike share users have low prevalence of helmet use, and few public bike share systems make helmets available. In summer 2016, a public bike share system launched in Vancouver, BC. Each bicycle is equipped with a free helmet, in response to BC's all-ages compulsory helmet law. This study assessed the prevalence of helmet use among adult cyclists on personal and public bicycles in Vancouver. METHODS: A survey of adult cyclists (age estimated at ≥16 years) at five screen line sites and at 15 public bike share docking stations was conducted...

Parasite distributions are constantly changing due to climate change, local and global movement of animals and humans, as well as land use and habitat change. The trematode Dicrocoelium dendriticum is a relatively recent invader of Canada, being first reported in eastern Canada in the 1930s and western Canada in the 1970s. However, historical records are scarce and its emergence is poorly understood. The establishment of this parasite in Canada provides an interesting opportunity to explore the use of population genetic approaches to help elucidate the invasion history of a relatively recently established helminth parasite...
