A real-world evaluation of the effectiveness and Sufficiency of Current Emergency Department Preventative Strategies for Reducing Emergency Department revisits in a Canadian children's hospital: a retrospective cohort study.

Background: Despite asthma guidelines' recommended emergency department preventative strategies (EDPS), repeat asthma-related emergency department (ED) visits remain frequent.

Methods: We performed a retrospective cohort study of children aged 1-17 years presenting with asthma to the Children's Hospital of Eastern Ontario (CHEO) ED between September 1, 2014 - August 31, 2015. EDPS was defined as provision of education on trigger avoidance and medication technique plus documentation of an asthma action plan, a prescription for an inhaled controller medication or referral to a specialist.

Predictors of future acute asthma visits among children receiving guideline recommended emergency department discharge management.

Background: Asthma emergency department (ED) visits remain frequent among children, prompting ongoing pursuit of preventative strategies.

Objective: We identified factors associated with future acute asthma ED visits among children who had already received guideline recommended discharge management following a prior asthma ED visit.

Methods: We performed a retrospective cohort study of children ages 1-17 years with a first asthma ED visit to the Children's Hospital of Eastern Ontario in Canada between September 2014-August 2015.

Mapping the preclinical to clinical evidence and development trajectory of the oncolytic virus talimogene laherparepvec (T-VEC): a systematic review.

Objective: This study aimed to conduct a systematic review of preclinical and clinical evidence to chart the successful trajectory of talimogene laherparepvec (T-VEC) from the bench to the clinic.

Design: This study was a systematic review. The primary outcome of interest was the efficacy of treatment, determined by complete response.

Assessing the Completeness of Reporting in Preclinical Oncolytic Virus Therapy Studies.

Irreproducibility of preclinical findings could be a significant barrier to the "bench-to-bedside" development of oncolytic viruses (OVs). A contributing factor is the incomplete and non-transparent reporting of study methodology and design. Using the NIH Principles and Guidelines for Reporting Preclinical Research, a core set of seven recommendations, we evaluated the completeness of reporting of preclinical OV studies.

Variation in lung function and nutritional decline in cystic fibrosis by genotype: An analysis of the Canadian cystic fibrosis registry.

Background: This study aimed to improve our understanding of the natural history of cystic fibrosis (CF) by comparing lung function and body mass index z-score (zBMI) between patients with different genotypes and identify a genotype with outcomes most comparable to homozygous ΔF508 patients.

Methods: Data was obtained from the Canadian CF Registry between January 1st 2007-January 1st 2016. Patients were categorized into one of five groups based on their genotype.

Complementary and alternative medicine use in children with asthma.

Purpose: To estimate the overall prevalence of complementary and alternative medicine and specific modalities used among children with asthma, identify predictors of use, and perceived positive or negative effects of therapies.

Results: Of the 161 children enrolled in the study, 76.4% had ever used complementary and alternative medicine.

Comparing Twitter data to routine data sources in public health surveillance for the 2015 Pan/Parapan American Games: an ecological study.

Objectives: This study examined Twitter for public health surveillance during a mass gathering in Canada with two objectives: to explore the feasibility of acquiring, categorizing and using geolocated Twitter data and to compare Twitter data against other data sources used for Pan Parapan American Games (P/PAG) surveillance.

Methods: Syndrome definitions were created using keyword categorization to extract posts from Twitter. Categories were developed iteratively for four relevant syndromes: respiratory, gastrointestinal, heat-related illness, and influenza-like illness (ILI).

Osteoarthritis of the hand I: aetiology and pathogenesis, risk factors, investigation and diagnosis.

Objective: Osteoarthritis (OA) of the hand can be a debilitating condition that hinders an individual's quality of life. With multiple joints within the hand that are commonly affected OA, an individual's ability to use their hand in everyday movements become more limited. The article aims to review literature on the aetiology and pathogenesis of OA, risk factors, characteristics of hand OA and the steps of diagnosis.

Osteoarthritis of the hand II: chemistry, pharmacokinetics and pharmacodynamics of naproxen, and clinical outcome studies.

Objective: This article aims to review osteoarthritis of the hand and the role of the non-steroidal anti-inflammatory drug (NSAID) naproxen on its management. We discuss the chemical and pharmacological properties of naproxen and the NSAID class, with an emphasis on its mechanism and adverse reactions. In the context of part I of this paper in characterizing hand osteoarthritis (OA), we review clinical trials that have been conducted involving hand OA and naproxen.
