Despite advances in obstetric care, preeclampsia (PE) remains the leading cause of maternal death and disability in both developed and developing countries, contributing to over 70,000 maternal and 500,000 fetal deaths annually worldwide. PULSE was designed using a preventative medicine approach, focusing on improving early detection of PE as opposed to managing symptoms after onset. The study aims to uncover the earliest possible signs of PE using a combination of novel clinical tools and established diagnostic techniques to better identify, track, and manage high risk pregnant women. Specifically, PULSE will be examining the incorporation of a non-invasive test for the measurement of arterial stiffness, which has been shown to be predictive of hypertensive disorders. This test, in combination with a wide range of blood biomarkers, detailed ultrasound imaging, and a comprehensive battery of physical and mental health questionnaires, represents the largest, most comprehensive preventative PE study to date. The results of this work has the potential to revolutionize the way PE and other hypertensive disorders of pregnancy are managed and treated and can serve to inform the design of future preventative clinical research studies.

Sudden cardiac death (SCD) remains a major cause of mortality within developed nations despite aggressive efforts to reduce its societal burden. Despite extensive clinical and genetic investigations, a subgroup of cardiac arrests remain unexplained, highlighting the potential contribution of additional cardiac conditions that may not be identified with contemporary diagnostic algorithms. The EPS ARREST study aims to evaluate the role of invasive electrophysiology study within this patient population.

This study is a multicenter prospective, parallel design, two-arm, rater-blinded randomized controlled pilot trial. Participants will be randomly assigned to one of two treatment conditions. In the first condition, treatment consists of rTMS sessions combined with Text4Support. The second condition is made up of the treatment as usual (rTMS sessions alone). The recruitment process is scheduled to last 12 months. It will involve active treatment for six weeks and follow-up period observation periods of 1,3, and 6 months for participants in both arms of the study. Participants will be recruited from four different centers for this project. Two centers (the Addiction and Mental Health clinic and the Alberta day hospital) will be from the large, sociodemographic diverse city of Edmonton in Alberta Western Canada. The remaining two centers will be in Halifax and Annapolis Valley in Nova Scotia, Canada.

Inflammatory Bowel Diseases (IBDs), including ulcerative colitis and Crohn's disease (CD), constitute a group of debilitating chronic diseases that profoundly impact patient quality of life and incurs large costs in terms of treatment and lost productivity. Incidence of IBD is rising worldwide, and there is a pressing clinical need for development of new therapies. Discovery and development of effective therapies to treat IBDs depend first on a better understanding of the underlying mechanisms, including how proinflammatory cells proliferate unchecked. It has been established that the cytokine interleukin (IL)-23 plays a pivotal role in IBD pathophysiology and antibodies targeting IL-23 are currently in late stage development for the treatment of both CD and ulcerative colitis (UC). IL-23 is part of the IL-12 family of cytokines (which includes IL-12, IL-27 and IL-35). The p40 subunit is shared among IL-23 and IL-12; the p19 subunit is unique to IL-23. Thus far, the efficacy of selective anti-IL-23 blockade (via anti-p19 antibodies) appears 5-10% better with respect to clinical and endoscopic outcomes than targeting both IL-23 and IL-12 using anti-p40 antibodies. Understanding the effects of IL-23 (and IL-12) in IBDs requires identification of the most relevant immune cells that respond to these cytokines. One likely cell type controlled by the IL-23 pathway are innate lymphoid cells (ILCs). ILC3s (a subset of ILCs) are dominant in healthy intestinal tissue and capable of producing IL-22 which maintain intestinal epithelial homeostasis. Disturbances in the amounts of IL-22 caused by changes in the stimulatory cytokine IL-23 in tissues, may therefore cause inflammatory responses. IL-23 may facilitate the IL-12-induced shift of ILC3s to ILC1s which are contributing to the disease-causing chronic inflammation. The DIVE 23 project is designed to understand the role of IL-23 in human IBD, in particular CD. It is hypothesized that IL-23R+ cells in the gut, are drivers of chronic inflammation in CD and determine the impact of IL-23 inhibition. To this end the investigators plan to extensively characterize the IL-23-responsive cell populations in inflamed and non-inflamed intestinal tissues of CD patients with postoperative recurrence in order to identify IL-23-responsive immune cell populations that are associated with disease activity. Patients will be treated in routine medical practice with biological agents and will undergo a second ileocolonoscopy 12-16 weeks later to investigate the impact of the different interventions on the mucosal immunology driving CD.

Exposure to electromagnetic field (EMF) emitted by mobile phones and devices with WIFI is on the rise and so is the EMF effects on sleep quality and well-being of individuals with high exposures to EMF. Some studies have shown poor sleep quality among individuals with long-term occupational exposure to EMF, and some have shown association between EMF long-term exposure and neuropsychiatric disorders including depression. This study aims to investigate a commercially available EMF- blocker blanket, called Sleepgift, that claims helping people to have a better sleep and improved health. We will investigate the Sleepgift efficacy on adults' quality of sleep and their vital signals as a measure of their well-being in a placebo-controlled single- blind cross-over designed study. Participants will sleep in our sleep lab at baseline and then 10 days later with the Sleepgift blanket after using it every night for the past 10 consecutive days. Participants will be given two blankets for each cycle of the study as it is a cross-over designed study: one Sleepgift and one regular blanket; they will not know which one is real or sham. There will be one-month washout period between the two cycles of the cross-over study. We aim to enroll 30 adults for the study. Participants' sleep quality will be measured by the established device called Prodogy; their vital signals will also be measured and monitored through the night. The collected data will be analyzed statistically for any significant effect of the Sleepgift blanket on sleep quality and vital signals such as heart's rhythm and heart rate variability.

Interstitial pneumonia with autoimmune features (IPAF) is a chronic interstitial lung disease (ILD) with some laboratoristic and/or clinical features of autoimmune disease, but without meeting criteria of connective tissue disease (CTD), and with no other causes of ILD. Despite recent efforts to standardize the diagnosis of IPAF, subjects with IPAF represent a very heterogenous group of patients, whose prognosis and clinical course are far from being clear. It also remains to be clarified what proportion of IPAF patients develop clear features of CTD over time. The aim of this observational trial is to define the clinical course of patients newly diagnosed with IPAF by prospectively following them for a period of 3 years, at 6-month intervals. The primary outcome will be 3-year lung transplant-free survival. The secondary outcome will be the proportion of patients who develop clinical and laboratoristic features clearly meeting criteria for a diagnosis of CTD at 3 years from the time of diagnosis of IPAF. Predictors of survival will also be studied.

This study will primarily identify longitudinal associations between cardiorespiratory fitness (CRF) and cognitive function pre- (baseline) to post-chemotherapy (\~3 months). This will be a prospective study of 50 BCS. We hypothesize that breast cancer patients undergoing chemotherapy who have higher levels of CRF at baseline will have significantly improved measures of attention, executive function, and memory post-chemotherapy. In addition, the exploratory aims will examine the longitudinal associations between physical activity (PA) and cognitive function from pre- to post-chemotherapy and explore the associations between inflammatory and non-inflammatory biomarkers and CRF with cognitive function.
