Multicenter Study Observational Study
Intrapleural Fibrinolysis for the Treatment of Indwelling Pleural Catheter-Related Symptomatic Loculations: A Multi-Center Observational Study.
Indwelling pleural catheters (IPCs) are an effective option in the management of malignant pleural effusion. Up to 14% of patients with IPCs develop symptomatic pleural loculations causing ineffective fluid drainage and breathlessness. To our knowledge, this is the first study to describe intrapleural fibrinolytic therapy for IPC-related symptomatic loculations. ⋯ Intrapleural fibrinolytic therapy can improve pleural fluid drainage and symptoms in selected patients with IPC and symptomatic loculation, but it carries a small risk of pleural bleeding. There is significant heterogeneity in its use currently, and further studies are needed to determine patient selection and optimal dosing regimen and to define its safety profile.

Randomized Controlled Trial
A randomized trial of 1% vs. 2% lignocaine by the spray-as-you-go technique for topical anesthesia during flexible bronchoscopy.
The optimal concentration of lignocaine to be used during flexible bronchoscopy (FB) remains unknown. This randomized controlled trial compared the efficacy and safety of 1% and 2% lignocaine solution for topical anesthesia during FB. ⋯ One percent lignocaine was found to be as effective as 2% solution for topical anesthesia during FB, albeit at a significantly lower dose as the latter. Thus, 1% lignocaine should be the preferred concentration for topical anesthesia during FB.

Randomized Controlled Trial
Effects of oropharyngeal exercises on snoring: a randomized trial.
Snoring is extremely common in the general population and may indicate OSA. However, snoring is not objectively measured during polysomnography, and no standard treatment is available for primary snoring or when snoring is associated with mild forms of OSA. This study determined the effects of oropharyngeal exercises on snoring in minimally symptomatic patients with a primary complaint of snoring and diagnosis of primary snoring or mild to moderate OSA. ⋯ Oropharyngeal exercises are effective in reducing objectively measured snoring and are a possible treatment of a large population suffering from snoring.

Up-to-date estimates of burden of diseases are required for evidence-based decision-making. The objectives of this study were to determine the excess costs of COPD and its trend from 2001 to 2010 in British Columbia, Canada. ⋯ The direct economic burden of COPD is high and has increased significantly between 2001 and 2010 over and above the increase in the health-care costs of the general population. Further investigation is required to elucidate the underlying reasons for the temporal increase in COPD direct costs.

Xpert MTB/RIF testing for Mycobacterium tuberculosis and rifampin resistance is being used extensively in countries with a high burden of TB. However, recent evidence suggests that it may not have the same accuracy or impact in high-income, low-burden TB countries. ⋯ In a predominantly Inuit population in a remote region of Canada where the burden of TB is high and no TB testing facilities are available, onsite Xpert testing was feasible and accurate and shortened the time to TB treatment initiation.
