Title: The Impact of a Home-based Pulmonary Telerehabilitation Program on Muscle Function and Quality of Life Following Acute Exacerbations of Chronic Obstructive Pulmonary Disease
Brief Summary: COPD impacts a significant proportion of the Veteran population. Acute exacerbations, or flare-ups, of COPD are associated with impaired muscle function and worse quality of life. Pulmonary rehabilitation, a formal exercise program for patients with lung disease that includes both endurance and strength training exercises, has been shown to improve muscle function and quality of life after an acute exacerbation of COPD. However, lack of geographically accessible rehabilitation facilities and/or transportation issues are often barriers to pulmonary rehabilitation attendance in the Veteran population. This study will assess the feasibility and impact of an eight-week, three sessions per week, home-based, pulmonary telerehabilitation program in Veterans with COPD following hospitalization for an acute exacerbation of their lung disease. We will measure adherence and satisfaction with the program and muscle strength, physical activity, quality of life, and exercise tolerance pre and post-intervention in Veterans randomized to the pulmonary telerehabilitation arm versus Veterans randomized to the control arm who do not participate in pulmonary rehabilitation.

Title: Administration of Prazosin to Prevent PTSD After Sexual Assault
Brief Summary: This study plans to learn more about whether taking the medication, Prazosin, immediately and during the weeks immediately following a traumatic event can help to reduce the risk of developing posttraumatic stress disorder (PTSD). Early post traumatic event sleep disturbance predicts the later development of PTSD. Prazosin has shown some effectiveness in reducing trauma related nightmares and sleep disturbance. We hypothesize that regulating sleep immediately after a sexual assault will reduce PTSD and diminish symptoms.

Title: Home-based Delivery of the Contraceptive Implant in Postpartum Guatemalan Women: a Cluster-randomized Trial
Brief Summary: Abstract

Background: Postpartum contraception is important to prevent unintended and closely spaced pregnancies following childbirth.

Methods: This study is a cluster-randomized trial of communities in rural Guatemala where women receive ante- and postnatal care through a community-based nursing program. When nurses visit women for their postpartum visit in the intervention clusters, instead of providing only routine care that includes postpartum contraceptive education and counseling, the nurses will also bring a range of barrier, short-acting, and long-acting contraceptives that will be offered and administered in the home setting, after routine clinical care is provided.

Discussion: A barrier to postpartum contraception is access to medications and devices. The study removes some access barriers (distance, time, cost) by providing contraception in the home. The community nurses were trained to place implants, which are a type of long-acting reversible contraceptive method that was previously only available in the closest town, which is about an hour away by vehicle. Therefore, the study examines how home-based delivery of routinely available contraceptives and the less routinely available implant may be associated with increased uptake of postpartum contraception within three months of childbirth. The potential implications of this study include: nurses may be able to be trained to safely provide contraceptives, including place implants, in the home setting, and provision of home-based contraception may be an effective way of delivering an evidence-based intervention for preventing unintended and closely spaced pregnancies in the postpartum period.

Title: Time Restricted Feeding and Metabolic Rhythms
Brief Summary: Current guidelines for the prevention and treatment of obesity focus on caloric restriction diets and increasing physical activity, but long-term compliance to these strategies is poor. The timing of meal intake relative to the light-dark and sleep-wake cycle is rarely considered in metabolic health; and modifying meal timing is likely easier to implement in daily life than reducing caloric intake and/or increasing physical activity. This project will test whether restricting the timing of energy intake to a short-defined period during wakefulness can be used to improve fuel utilization patterns and enhance circadian rhythms in metabolic tissues to optimize health.

Title: Folic Acid Supplementation in Children With Sickle-Cell Disease: A Randomized Double-Blind Cross-Over Trial
Brief Summary: Folic acid supplementation (1mg/d) is the standard recommendation for Canadian children with Sickle cell disease (SCD), even though it can provide up to six times the recommended intake amount for healthy children. There is growing concern that too much folic acid can be detrimental to health as high folate levels and circulating unmetabolized folic acid (UMFA), which occurs in blood with doses of folic acid as low as 0.2mg/d, have been associated with accelerated growth of some pre-cancerous cells, and altered DNA methylation and gene expression.

To inform the efficacy and potential harm of high-dose folic acid supplementation in Canadian children with SCD, a double-blind randomized controlled cross-over trial is proposed. Children with SCD (n=36, aged 2-19 y) will be recruited from BC Children's Hospital and randomized to initially receive 1 mg/d folic acid or a placebo for 12-weeks (wk). After a 12-wk washout period, treatments will be reversed.
