Staphylococci and enterococci account for most deep infections associated with bone-anchored percutaneous implants for amputation treatment. Implant-associated infections are difficult to treat; therefore, it is important to investigate if these infections have a biofilm origin and to determine the biofilm antimicrobial susceptibility to improve treatment strategies. The aims were: (i) to test a novel combination of the Calgary biofilm device and a custom-made susceptibility MIC plate (Sensititre(®) ), (ii) to determine the biofilm formation and antimicrobial resistance in clinical isolates causing implant-associated osteomyelitis, and (iii) to describe the associated clinical outcome...

BACKGROUND: Intracavitary pulmonary aspergilloma is a chronic, debilitating fungal infection. Without definitive therapy, death can occur from massive hemoptysis, cachexia, or secondary infection. Although surgical resection is the standard therapy, it is not possible for many patients owing to poor pulmonary function or medical comorbidities. Aspergilloma removal through bronchoscopy is an important alternative therapy that may be available in select cases. METHODS: We retrospectively reviewed all cases referred to the University of Calgary Interventional Pulmonary Service for transbronchial removal of intracavitary aspergilloma from January 1, 2009, to January 1, 2014...

An outbreak of Legionnaires' disease occurred in an inner city district in Calgary, Canada. This outbreak spanned a 3-week period in November-December 2012, and a total of eight cases were identified. Four of these cases were critically ill requiring intensive care admission but there was no associated mortality. All cases tested positive for Legionella pneumophila serogroup 1 (LP1) by urinary antigen testing. Five of the eight patients were culture positive for LP1 from respiratory specimens. These isolates were further identified as Knoxville monoclonal subtype and sequence subtype ST222...

OBJECTIVES: Although there is an accepted benchmark for adenoma detection rate (ADR) in average risk screening colonoscopy, a benchmark for ADR or the associated quality indicator, adenomas per colonoscopy (APC), for colonoscopies performed for a positive fecal immunochemical test (FIT+) has not been established. The purpose of this study was to propose methods for establishing a benchmark ADR and APC for FIT+ patients. METHODS: In this historical cohort study, we included 15,329 patients aged 50-74 years who underwent a colonoscopy at Alberta Health Services' Colon Cancer Screening Centre, Calgary, Canada, from 1 January 2014 to 30 June 2015 for either investigation of a positive FIT or average risk screening...

Patient evaluations of physician communication are widely used, but we know little about how these relate to professionally agreed norms of communication quality. We report an investigation into the association between patient assessments of communication quality and an observer-rated measure of communication competence. Consent was obtained to video record consultations with Family Practitioners in England, following which patients rated the physician's communication skills. A sample of consultation videos was subsequently evaluated by trained clinical raters using an instrument derived from the Calgary-Cambridge guide to the medical interview...

OBJECTIVES: While reference limits are foundational to interpreting clinical laboratory tests, they may not correspond to the actual values triggering clinical response. We propose to measure this using clinical action curves, which plot test values against an indicator of clinical action. METHODS: We selected repeat test ordering as a quantifiable, objective, useful measure that is readily calculable using available laboratory data. Using all results in Calgary in 2010-2011 for eight analytes, clinical action curves for each analyte were plotted as the relationship between index test value and retesting hazard, modeled using Cox proportional hazards with restricted cubic splines...

Despite strong evidence of a clinical benefit from initiating antiretroviral therapy (ART) immediately after diagnosis some patients remain ART naïve. We examined explanations, over a four-year period in a centralized HIV clinical cohort under universal health care, for newly diagnosed patients, while being fully engaged and retained in HIV care, delaying ART initiation for >180 days following their HIV diagnosis. All patients followed at the Southern Alberta Clinic, Calgary, Canada between 1 January 2010 and 1 January 2014 were included and followed until they moved, were lost to follow-up, died or until 1 January 2015...

BACKGROUND: The neighbourhood environment may play an important role in diet quality. Most previous research has examined the associations between neighbourhood food environment and diet quality, and neighbourhood socioeconomic status and diet quality separately. This study investigated the independent and joint effects of neighbourhood food environment and neighbourhood socioeconomic status in relation to diet quality in Canadian adults. METHODS: We undertook a cross-sectional study with n = 446 adults in Calgary, Alberta (Canada)...

Much has been written about the global implementation of the Calgary Family Assessment and Intervention Models (CFAM/CFIM) and the application of these practice models in various clinical settings. The purpose of this article is to provide a brief update on the background of CFAM/CFIM, and the current applications of the models as evidenced in the English-language literature. Little has been written about the use of CFAM/CFIM in a personal context, however. As originators of the models, we offer our own narratives and reflections about the reciprocity between the personal and professional applications of our models and the ways that our personal experiences have extended our understanding about the utility of the models for clinical practice with families...

We present preliminary results from a method for estimating the optimal effective permittivity for reconstructing microwave-radar images. Using knowledge of how microwave-radar images are formed, we identify characteristics that are typical of good images, and define a fitness function to measure the relative image quality. We build a polynomial interpolant of the fitness function in order to identify the most likely permittivity values of the tissue. To make the estimation process more efficient, the polynomial interpolant is constructed using a locally and dimensionally adaptive sampling method that is a novel combination of stochastic collocation and polynomial chaos...
