A multiple instance learning (MIL) method, extended Function of Multiple Instances (eFUMI), is applied to ballistocardiogram (BCG) signals produced by a hydraulic bed sensor. The goal of this approach is to learn a personalized heartbeat "concept" for an individual. This heartbeat concept is a prototype (or "signature") that characterizes the heartbeat pattern for an individual in ballistocardiogram data. The eFUMI method models the problem of learning a heartbeat concept from a BCG signal as a MIL problem...

Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), and Trichomonas vaginalis (TV) are sexually transmitted infections (STIs) associated with adverse birth outcomes. Untreated partners contribute to high rates of STI reinfection; thus, partner notification and treatment remain important components of STI care and control. A prospective cohort study was conducted among 300 pregnant women presenting to the antenatal clinic at Princess Marina Hospital in Gaborone, Botswana who enrolled in an STI screening study...

Reliable species identification provides a sounder basis for use of species in the order Odonata as biological indicators and for their conservation, an urgent concern as many species are threatened with imminent extinction. We generated 134 COI barcodes from 36 morphologically identified species of Odonata collected from Mindanao Island, representing 10 families and 19 genera. Intraspecific sequence divergences ranged from 0 to 6.7% with four species showing more than 2%, while interspecific sequence divergences ranged from 0...

: 98 Background: VTE represents a significant risk for morbidity and mortality in cancer patients. Hospitalized solid tumor patients at PM are especially at risk (15% of inpatients experienced a VTE event in 2004 when prophylaxis rate was 19%). Institution-wide VTE prophylaxis policy was implemented, and prophylaxis uptake reached nearly 97% in Sept 2012. We are interested in whether the prophylaxis policy made any impact in reducing VTE incidences over time. Our objective is to compare inpatient VTE frequency before and after the implementation of the VTE prophylaxis policy (IPP) in Sept 2012 at PM...

: 67 Background: Patient-reported outcome measures (PROMs) are used to collect cancer-related symptom and symptomatic toxicity data. Understanding factors that affect the acceptability of PROMs is useful for improving the participation of such routine screening practices. We investigated the association between patient's functional status on their acceptance and perception of usefulness of tablet technology to routine collection of PROM data in the clinical setting. METHODS: 279 adult cancer outpatients at Toronto's Princess Margaret Cancer Centre completed two physical function surveys, the HAQ-DI and WHODAS, using touchscreen tablet technology...

The aim of this study was to review the outcomes of a series of breast cancer patients who underwent sentinel node biopsy inclusive of lymphoscintigraphy, and to assess the incidence of internal mammary node (IMN) metastatic positivity at exploration and whether these findings influenced treatment. Between April 2001 and December 2012, 581 breast cancer patients at Princess Alexandra Hospital underwent preoperative lymphoscintigraphy in the course of the performance of sentinel node biopsy. Analysis was performed of those patients who demonstrated radio-isotope uptake to the IMN chain, and who had sentinel node biopsy of the IMN's and were found to have metastatic involvement...

INTRODUCTION: Economic analyses of upcoming treatments for lung cancer benefit from real-world health utility scores (HUSs) in an era of targeted therapy. METHODS: A longitudinal cohort study at Princess Margaret Cancer Centre evaluated 1571 EQ5D-3L-derived HUSs in 475 outpatients with metastatic lung cancer across various disease states. Patients with epidermal growth factor receptor (EGFR) (n = 183) and anaplastic lymphoma kinase (ALK) (n = 38) driver alterations were enriched through targeted enrolment; patients with wild-type non-small-cell lung cancer (WT NSCLC) (n = 224) and small-cell lung cancer (SCLC) (n = 30) were sampled randomly...

BACKGROUND: Perioperative respiratory adverse events (PRAE) are the most common critical incidents in paediatric anaesthesia and occur more often in infants. Use of laryngeal mask airways (LMAs) is associated with reduced PRAE compared with endotracheal tubes in older children (>1 year). We aimed to evaluate the effect of these devices on the incidence of PRAE in infants. METHODS: We did a randomised controlled trial at the Princess Margaret Hospital for Children in Perth (WA, Australia) by recruiting infants (aged 0-12 months) undergoing general (with or without regional or local) anaesthesia with anticipated fentanyl dose 1 μg/kg or lower for minor elective surgery...

B Burgdorf, G Freedman, B Teo
PURPOSE: The current standard CTV-to-PTV expansion for whole breast radiotherapy (WBRT) is 7mm, as recommended by RTOG-1005.This expansion is derived from the uncertainty due to patient positioning (±5mm) and respiratory motion (±5mm). We evaluated the expansion needed for respiratory motion uncertainty using 4DCT. After determining the appropriate expansion margins, RT plans were generated to evaluate the reduction in heart and lung dose. METHODS: 4DCT images were acquired during treatment simulation and retrospectively analyzed for 34 WBRT patients...

BACKGROUND: Patients with lung cancer are at increased risk for venous thromboembolism (VTE), particularly those receiving chemotherapy. It is estimated that 8% to 15% of patients with advanced non-small-cell lung cancer (NSCLC) experience a VTE in the course of their disease. The incidence in patients with specific molecular subtypes of NSCLC is unknown. We undertook this review to determine the incidence of VTE in patients with ALK (anaplastic lymphoma kinase)-rearranged NSCLC. PATIENTS AND METHODS: We identified all patients with ALK-rearranged NSCLC diagnosed and/or treated at the Princess Margaret Cancer Centre (PM CC) in Canada between July 2012 and January 2015...

BACKGROUND: Seasonal Malaria Chemoprevention (SMC) is currently recommended for children under five in areas where malaria transmission is highly seasonal. We explored children's caregivers' and community health workers' (CHWs) responses to an extended 5-month SMC programme. METHODS: Thirteen in-depth interviews and eight focus group discussions explored optimal and suboptimal 'uptake' of SMC to examine facilitators and barriers to caregivers' uptake. RESULTS: There did not appear to be major differences between caregivers of children with optimal and sub-optimal SMC uptake in terms of their knowledge of malaria, their perceptions of the effect of SMC on a child's health, nor their understanding of chemoprevention...
