Project description:BackgroundDuring the Coronavirus disease (COVID-19) pandemic, countries implemented border control and quarantine measures to reduce transmission. The Alberta Border Testing Pilot Program (ABTPP) allowed international travellers entering Alberta to reduce their quarantine period following two negative COVID-19 tests. We evaluated participant experiences with the ABTPP and implementation.MethodWe used a parallel convergent mixed-methods design to explore participant experiences through electronic web-based questionnaires (n = 21,089; n = 13,839) and semi-structured telephone interviews (n = 30). We evaluated implementation through three staff focus groups (n = 11). We analysed questionnaires using descriptive statistics and analysed interviews using inductive and deductive thematic analysis. We deductively coded focus group data using the 2009 Consolidated Framework for Implementation Research (CFIR).ResultsQuestionnaires indicated minimal issues with registration forms (91.7%), symptom reports (95.5%), and COVID-19 testing (95.7%). Most respondents (95.1%) expressed willingness to participate in the ABTPP again. Interviews revealed three themes related to participant experience: program efficiency, clarity of information, and requisite effort. Focus groups identified key implementation facilitators including the single health information system, strong stakeholder partnerships, and good communication across partnerships. Barriers included program complexity, implementation timeline, and evolving external context.DiscussionParticipants reported high satisfaction with the ABTPP. Border testing programs should have high efficiency, require low effort, and use messaging that is clear and consistent. The effective implementation of border testing programs may be facilitated by strong leadership, adaptability, automated components, good communication, and simple technology. Learnings from participants and staff may help improve the implementation of border control programs for future pandemics or other emergencies.ConclusionsThe ABTTP was a novel border control measure during the COVID-19 pandemic. Our evaluation of both participant and staff experiences demonstrated high levels of traveller satisfaction and identified areas for improvement that can inform the development of future border control measures.

Project description:BACKGROUND:Historical changes in the nature of sedentary activities have been observed in other countries, but it is not clear if similar trends exist in Canada. It is also unclear how changes in the measurement of sedentary behaviour affects national estimates. Our objective is to document all sources and measures of sedentary behaviour from Canadian, nationally representative surveys, and report on selected estimates of time spent in sedentary activities. Lessons learned can benefit the wider international surveillance community. METHODS:We describe and document all data sources of sedentary behaviour at the national level in Canada, and report on selected prevalence data from repeated cross-sectional surveys. We summarize amounts of total device-assessed sedentary time and self-reported sedentary activities (e.g., passive travel, leisure television, computer, video games, screen, and reading) by age group over time. RESULTS:Nineteen national surveys were identified. Changes in questions and/or response categories precluded direct assessment of trends over time for some measures; however, certain trends were observed. Accelerometer-measured sedentary time, leisure reading (among those < 50 years) and television/video viewing in younger age groups have remained relatively stable (with a possible slight decline in television/video viewing). Time spent in passive travel and leisure computer and electronic device use appears to have increased. Television and video viewing appears to have increased in older adults while their leisure reading appears to have fallen. CONCLUSIONS:Changes in measurement of sedentary behaviour can affect estimates and reduce comparability over time. Total leisure screen use appears to have increased over time, reflecting the ways in which Canadians spend their free time and technological advances. The main public health message is the need for continued efforts to reduce leisure screen use, especially among youth and older adults.

Project description:ObjectiveTo provide insights and strategies for pegvaliase management in challenging cases with phenylketonuria (PKU) based on the first 5 years of experience with pegvaliase in real-world clinical practice.MethodsTwelve PKU experts gathered during a one-day, in-person meeting to discuss clinical cases illustrating important lessons from their experiences treating patients with pegvaliase in real-world clinical practice. Challenges with pegvaliase experienced prior to and during treatment and corresponding strategies to overcome them were discussed.ResultsTwelve cases of adults with PKU (eight females and four males, aged 18 to 68 years) receiving pegvaliase were reviewed and discussed. Challenges of the cases included medical or mental health comorbidities, executive function deficits, challenging social or socioeconomic situations, logistical or geographic barriers, or a combination of these; one was considering pregnancy. Despite challenges, pegvaliase was initiated successfully in most cases. Strategies to overcome barriers included individualized education, including side effect action plans, help from support organizations, collaboration with local providers, and use of telemedicine. Recommendations from the clinicians included that comorbid conditions should be monitored closely after treatment initiation and may require collaboration with other healthcare providers. A collaborative relationship with the clinic, ongoing education, and supportive relatives or friends can help individuals to remain adherent to pegvaliase. Suboptimal adherence may be addressed by a daily reminder system, telemedicine, in-home support, or a modified titration plan. Treated individuals with eating disorders require additional follow-up and support to achieve a healthy relationship with food. In most cases, including late-diagnosed individuals, reduced blood Phe levels resulted in improved PKU-related symptoms, including neurological issues.ConclusionExperience from the presented cases and 5 years of expert experience with pegvaliase in the real-world setting provide insight and guidance for healthcare professionals initiating and managing pegvaliase treatment in complex PKU cases. These cases demonstrate that, through comprehensive assessment and addressing barriers, pegvaliase treatment can be successful in adults with PKU, regardless of prior treatment success, age, socioeconomic, cognitive, or executive function challenges, as well as in those with comorbidities or considering pregnancy. Ongoing documentation of clinical experience is crucial for advancing the management of individuals receiving this treatment.

Project description:Introduction: Peri-operative window trials, using molecular biomarkers as surrogate endpoints for treatment response, offer investigators a uniqueopportunity to obtain intact tumor samples at 2 different time-points and thus evaluate potential biomarkers over a short period of time. Here we report results of a pilot trial designed to determine if treatment-mediated changes in gene expression can be detected after a 10-day exposure to anastrozole in estrogen receptor (ER)-positive breast cancer compared to untreated controls. Methods: Paired tumor samples (biopsy and surgical) were obtained from 26 postmenopausal women with ER-positive breast cancer. Patients were assigned anastrozole (1mg/dy) for 10 days immediately prior to surgery (13 cases) or no treatment (13 controls). 502 cancer-related genes were examined by the DASL FFPE-based cDNA array (moderated t-test, p ≤ .005). Surrogate biomarkers reflecting changes in gene expression were examined by immunohistochemistry (IHC) (Wilcoxon rank-based test, p < .05). Results: Sufficient RNA was available from 19 paired samples (8 controls, 11 cases). There was no difference in age, tumor size, grade, or baseline biomarker expression between groups. Within each group, 18 genes, reflecting roles in proliferation, angiogenesis, and apoptosis showed differential expression over time from biopsy to surgery (p < 0.005). Dysregulation of estrogen-related genes was present only in the treated group. Comparison between groups identified 5 genes that were significantly dysregulated between controls and treated cases (BAG1/ING1/ERBB4/IFNGR1/TFDP1). Reduction in Ki-67 index was observed in 7 (54%) treated cases in 1 (7.7%) control patient. Conclusions: Short-term (10-day) exposure to anastrozole resulted in significant dysregulation of 18 out of 502 cancer-related genes, and Ki-67 was reduced in 54% of cases. However, the local effects of wound healing may represent a confounding factor in the interpretation of peri-operative window trials as exposed by the changes in gene expression and the increased Ki-67 index in the control group.
