OBJECTIVES: Sulfonylureas have been inconsistently associated with increased cardiovascular mortality in patients with type 2 diabetes mellitus. However, there are no existing studies of long-term risk in South Asian and Chinese populations. Our objective was to determine whether sulfonylureas are associated with increased mortality or cardiovascular disease in a population cohort of South Asian, Chinese and other Canadian patients with incident diabetes. METHODS: We studied a population-based cohort of adults 35 years of age or older who had diabetes and had been diagnosed between April 2004 and March 2014 by using administrative databases from British Columbia...

OBJECTIVES: The current gold-standard for the first-line treatment in IIIb/IV stages of epithelial ovarian cancer (EOC) is the combination of carboplatin and paclitaxel plus bevacizumab in some countries. In the era of personalized medicine, there is still uncertainty on the impact of several molecularly targeted agents, which have been investigated for the management of this disease. To shed light on the actual role of targeted therapy in EOC, a systematic review and meta-analysis was performed...

OBJECTIVES: Long-acting bronchodilators are mainstay treatment for moderate to severe chronic obstructive pulmonary disease. A growing body of evidence indicates an increased risk of cardiovascular events upon initiation of these medications. We hypothesize that this risk is higher in patients with chronic obstructive pulmonary disease who had a preexisting cardiovascular disease regardless of receipt of any cardiovascular medication. METHODS: A retrospective cohort of patients with a diagnosis of chronic obstructive pulmonary disease based on two outpatient visits or one inpatient visit for chronic obstructive pulmonary disease (International Classification of Diseases, 9th Edition, Clinical Modification codes 491...

OBJECTIVE: Antihypertensive medication nonadherence is significant contributor to poor BP control. Patient-related factors (lack of motivation or risk understanding) are important. The aim of PRISMA study was to determine the impact of integrated approach with therapy based on perindopril arginine in the improvement of motivation, adherence to antihypertensive treatment and BP control. DESIGN AND METHOD: 906 (315 male, 56.0 ± 10.6 years) non-adherent (score < 4 in Morisky and Green Test for Measure of Adherence to Therapy) hypertensive patients with planning or action stages of behavior changes (Prochaska and DiClemente model) with uncontrolled hypertension (BP > 140/90 mmHg) were randomly assigned to 2 strategies: integrated approach with therapy based on perindopril arginine with added-on therapy if necessary (G1, n = 755) or routine practice (G2, n = 151)...

Segmentation of infarcts at hyperacute stage is challenging as they exhibit substantial variability which may even be hard for experts to delineate manually. In this paper, a sparse representation based classification method is explored. For each patient, four volumetric data items including three volumes of diffusion weighted imaging and a computed asymmetry map are employed to extract patch features which are then fed to dictionary learning and classification based on sparse representation. Elastic net is adopted to replace the traditional L0-norm/L1-norm constraints on sparse representation to stabilize sparse code...

There is a clear clinical need for high specificity plasma biomarkers for predicting risk of venous thromboembolism (VTE), but thus far such markers have remained elusive. Utilising affinity reagents from the human protein atlas (HPA) project and multiplexed immuoassays we extensively analysed plasma samples from two individual cohorts to identify candidate protein markers associated with VTE risk. We screened plasma samples from 88 VTE cases and 85 matched controls, collected as part of the Swedish 'Venous Thromboembolism Biomarker Study' (VEBIOS), using suspension bead arrays composed of 755 antibodies targeting 408 candidate proteins...

Activation of the inflammatory generating complement system might play a pathogenic role in spontaneous subarachnoid hemorrhage (SAH). We studied whether plasma and cerebrospinal fluid (CSF) levels of complement proteins were associated with angiographic vasospasm and cerebral ischemic lesions after SAH. Ficolin-1 (M-ficolin), ficolin-3 (H-ficolin), mannose-binding lectin (MBL), MBL-associated serine protease 2 (MASP-2), MASP-3, and MAp44 were analyzed in plasma of 45 SAH patients at 24 h after bleeding. Additionally, ficolin-1 levels were measured in cerebrospinal fluid (CSF) samples obtained 24 h after bleeding in 19 patients with external ventricular drainage placement...

To date there has been no employment of a magnetoelastic (ME) biosensor method to detect S. Typhimurium in soil. The ME biosensor method needs to be investigated and modified for its successful performance. Filtration, cation-exchange resin method, and combinations of both methods were employed for the extraction of S. Typhimurium from soil, and the number of S. Typhimurium and the resonant frequency shift of the ME sensor were then compared using a brilliant-green-sulfa agar plate and an HP 8751A network analyzer...

Background and aims: Recently novel picosecond duration lasers (ps-lasers) have been developed for the treatment of multicolored and recalcitrant tattoos, and safety and efficacy have been reported. We therefore hypothesized that the ps-laser could be an alternative treatment for dermal pigmented lesions and performed a retrospective review to evaluate the efficacy and safety of the ps-laser. Subjects and methods: A retrospective photographic review of 10 patients with dermal pigmented lesions was performed (ages from 4 months to 52 yr), 6 nevus of Ota, 3 ectopic Mongolian spots and 1 Mongolian spots...

Transscleral drug delivery may become a safe alternative to the intravitreal injection for chronic retinal diseases such as age-related macular degeneration or diabetic macular edema. However, the drug delivered onto the sclera subjects to vigorous clearance by episcleral and choroidal circulation; in addition, the penetration from episclera to retina needs to overcome counter-directional ocular fluid current driven by intraocular pressure (IOP) as well as unfavorable drug disposition exerted by drug transporters before the drug reach retina...

Studies extending across multiple life stages promote an understanding of factors influencing health across the life span. Existing work has largely focused on individual-level rather than area-level early life determinants of health. In this study, we linked multiple data sets to examine whether early life state-level characteristics were predictive of health and mortality decades later. The sample included 143,755 U.S. employees, for whom work life claims and administrative data were linked with early life state-of-residence and mortality...

OBJECTIVE: Hypoxia is a recognised complication of procedural sedation. This study sought to determine whether there was an association between the use of high-flow oxygen delivery by a non-rebreather (NRB) mask during ED procedural sedation and decreased rates of hypoxia when compared with alternative oxygenation methods. METHODS: Records of all procedural sedations performed over a 12 month period in an Australian tertiary ED were reviewed retrospectively. The primary outcome was whether recorded oxygen saturations fell below 90%...

INTRODUCTION: Upper airway measurement can be important for the diagnosis of breathing disorders. Acoustic reflection (AR) is an accepted tool for studying the airway. Our objective was to investigate the differences between cone-beam computed tomography (CBCT) and AR in calculating airway volumes and areas. METHODS: Subjects with prescribed CBCT images as part of their records were also asked to have AR performed. A total of 59 subjects (mean age, 15 ± 3.8 years) had their upper airway (5 areas) measured from CBCT images, acoustic rhinometry, and acoustic pharyngometry...
