Information leaflets have been shown to positively or negatively impact adherence, depending on their content. The objective of this study was to perform an appraisal of the consumer information provided in COPD inhaler monographs. Methods. COPD inhalers were identified from the Health Canada Drug Product Database. Medication information and instructions for inhaler use were analyzed for readability by seven formulas, with an acceptability threshold of grades 6–8. Three researchers rated suitability using a modified Suitability Assessment of Materials (SAM) tool and assessed leaflets for explicit warnings. Results. Twenty-six inhalers with a COPD indication were evaluated. Medication information sections were rated as “difficult to read” or “hard,” and 85% (22/26) had a reading level above grade 8. The instructions for inhaler use were rated as “easy” or “fairly easy” to read and 63% (16/26) met the threshold by all formulas. While all leaflets achieved superior suitability ratings, extreme warnings included risk of premature death (), risks of serious injury (), serious interactions (), and statements that convey a serious consequence to therapy (). Conclusion. While COPD information leaflets in Canada performed well in terms of readability and suitability, overemphasis on side effects, warnings, and precautions may contribute to patient fear and nonadherence.Item The development, implementation and evaluation of clinical pathways for chronic obstructive pulmonary disease (COPD) in Saskatchewan: protocol for an interrupted times series evaluation(BioMed Central, 2017-11-28) Rotter, Thomas; Plishka, Christopher; Hansia, Mohammed Rashaad; Goodridge, Donna; Penz, Erika; Kinsman, Leigh; Lawal, Adegboyega; O'Quinn, Sheryl; Buchan, Nancy; Comfort, Patricia; Patel, Prakesh; Anderson, Sheila; Winkel, Tanya; Lang, Rae Lynn; Marciniuk, DarcyIntroduction Hospital and emergency department discharge for patients with chronic obstructive pulmonary disease (COPD) is often poorly organised. We developed a patient-centred, evidence-based and consensusbased discharge care bundle for patients with acute exacerbations of COPD. Methods A purposeful sample of clinicians and patients were invited to participate in a two-round Delphi study (July–November 2015). In round 1, participants rated on a seven-point Likert scale (1=not at all important; 7=extremely important) the importance of 29 unique COPD care actions. Round 2 comprised items selected from round 1 based on consensus (>80%endorsement for Likert values 5–7). A list of 18 care items from round 2 was discussed in a face-to-face nominal group meeting. Results Seven care items were included in the COPD discharge bundle based on clinician and patient input: (1) ensure adequate inhaler technique is demonstrated; (2) send discharge summary to family physician and arrange follow-up; (3) optimise and reconcile prescription of respiratory medications; (4) provide a written discharge management plan and assess patient’s and caregiver’s comprehension of discharge instructions; (5) refer to pulmonary rehabilitation; (6) screen for frailty and comorbidities; and (7) assess smoking status, provide counselling and refer to smoking cessation programme. Conclusion We present a seven-item, patient-centred, evidence-based and consensus-based discharge bundle for patients with acute exacerbations of COPD. Alignment with clinical practice guidelines and feasibility of local adaptations of the bundle should be explored to facilitate wide applicability and evaluation of the effectiveness of the COPD discharge bundle.Item Performance of the odour span task is not impaired following inactivations of parietal cortex in rats(2018) Scott, Gavin; Zabder, Nadine; Greba, Quentin; Howland, JohnItem Acute stress, but not corticosterone, facilitates acquisition of paired associates learning in rats using touchscreen-equipped operant conditioning chambers(Elsevier, 2018) Roebuck, Andrew; Liu, Max; Lins, Brittney; Scott, Gavin; Howland, John G.Item Development of a patient-centred, evidence-based and consensus-based discharge care bundle for patients with acute exacerbation of chronic obstructive pulmonary disease(British Thoracic Society, 2018-01-30) Ospina, Maria; Michas, Marta; Deuchar, Lesly; Leigh, Richard; Bhutani, Mohit; Rowe, Brian; Marciniuk, Darcy; Goodridge, Donna; Dechman, Gail; Bourbeau, Jean; Balter, Meyer; Camp, Pat; Hernandez, Paul; Goldstein, Roger; Stickland, MichaelIntroduction: Hospital and emergency department discharge for patients with chronic obstructive pulmonary disease (COPD) is often poorly organised.

The aim of this study was to determine the prevalence of sinus problems in farming and non-farming rural populations and further investigate the association of individual (for example life-style, occupational), contextual (e.g., environmental), and important covariates (e.g., age, sex) with sinus problems. A large-scale cross-sectional study was conducted in farm and non-farm residents of rural Saskatchewan, Canada. A logistic regression model based on a generalized estimating equations approach were fitted to investigate the risk factors of sinus problems. Sinus problems were reported by 2755 (34.0%) of the 8101 subjects. Farm residents were more likely to spend their first year of life on farm compared with non-farm residents, and indicated a significantly lower risk of sinus problems. Meanwhile, occupational exposure to solvent and mold were associated with an increased risk of sinus problems. Some health conditions such as allergy and stomach acidity/reflux, family history, and female sex were also related to a higher risk of sinus problems. Farm residents had a significantly lower risk of sinus problems than non-farm residents, likely due to the exposure to farm specific environments in their early life.Item Interpretation of Spirometry in Saskatchewan First Nations Adults(Annals of the American Thoracic Society, 2018-10-01) Fenton, Mark; Graham, Brian; Stanojevic, Sanja; Whitford, Lorna; Ironstand, LaurieThe Canadian First Nations and Inuit communities bear a large burden of respiratory disease, with increased rates of smoking, respiratory infections, asthma, chronic obstructive lung disease, and hospitalizations (1). Identification of respiratory disease and classification has relied on spirometric reference values from white individuals, or in the case of the Global Lung Initiative (GLI) dataset, “other” (2), because there are no published reference values for Canadian First Nations individuals. Several studies have suggested that spirometric values for Canadian Inuit populations may be different from those for white populations (3–7), but these observations are not consistent (7–10). This study investigated whether lung function measured in Plains Cree adults differed from that expected in white adults. Part of the data reported in this letter was presented at the 2014 American Thoracic Society International Conference in abstract form (11).Item Fast oxygen dynamics as a potential biomarker for epilepsy(Nature Research, 2018-12-18) Farrell, Jordan S.; Greba, Quentin; Snutch, Terrance P.; Howland, John G.; Teskey, G. CampbellChanges in brain activity can entrain cerebrovascular dynamics, though this has not been extensively investigated in pathophysiology. We assessed whether pathological network activation (i.e. seizures) in the Genetic Absence Epilepsy Rat from Strasbourg (GAERS) could alter dynamic fluctuations in local oxygenation. Spontaneous absence seizures in an epileptic rat model robustly resulted in brief dips in cortical oxygenation and increased spectral oxygen power at frequencies greater than 0.08 Hz. Filtering oxygen data for these fast dynamics was sufficient to distinguish epileptic vs. non-epileptic rats. Furthermore, this approach distinguished brain regions with seizures from seizure-free brain regions in the epileptic rat strain. We suggest that fast oxygen dynamics may be a useful biomarker for seizure network identification and could be translated to commonly used clinical tools that measure cerebral hemodynamics.Item The T-type calcium channel antagonist, Z944, alters social behavior in Genetic Absence Epilepsy Rats from Strasbourg(Elsevier, 2019) Marks, Wendie; Zabder, Nadine; Cain, Stuart; Snutch, Terrance; Howland, John G.
