Periodontal disease is a chronic condition affecting the teeth and surrounding support structures, characterized by tooth loss and alveolar bone loss. Sanative therapy (ST) is the gold standard non-surgical treatment for periodontal disease and involves mechanically removing the subgingival bacteria from the periodontal pockets. Regular periodontal maintenance appointments are needed to maintain periodontal health after ST. Moreover, the periodontal health of individuals not requiring ST is also dependent on regular hygiene appointments. Due to Ontario's March 2020 COVID-19-related clinic closure for approximately 3 months along with a reduced numbers of appointments available due to guidelines of professional bodies and public health beyond this period of time, many appointments were considerably delayed or cancelled. The effects of this disruption to periodontal health in male and female patients who have undergone ST and continue with maintenance appointments or who attend for regular hygiene appointments have not yet been investigated.
The primary objectives of the study are to identify a setrusumab dosing strategy in participants with OI and to evaluate the effect of setrusumab vs placebo on reduction in fracture rate.
The CANCOV study will be the first Canadian study to provide a comprehensive evaluation of early, and 1-year, outcomes of outpatient and hospitalized COVID-19 survivors and their family caregivers, their varied trajectories and associated clinical risk factors. The overall objectives are to determine short- (in hospital) and longer-term (1, 3, 6 and 12 months post-acute hospital discharge) outcomes COVID-19+ patients across the spectrum of symptom severity, including outpatients and inpatients from GIM and ICU wards and their caregivers, and the clinical, sociodemographic, multi-omic predictors of these outcomes. By leveraging expertise from investigators across disciplines and divisions, this study presents a suite of complementary projects that explore the genetic, transcriptomic, epigenomic and immunologic evaluation of COVID-19 infection across the illness and recovery trajectory during the acute illness and in the context of multidimensional long-term outcomes. As there continues to be need for longer term follow up and research on Long-COVID, this study has added an optional extension to include 2-year, 3-year, 4-year and 5 year outcomes.
Insomnia is defined as the inability to fall asleep or stay asleep at night and it is one of the most prevalent sleep disorders that can have deleterious impacts on health and this population's quality of life. Currently, both pharmaceutical interventions (trazodone) and cognitive behavioral therapy (CBTi) are widely used to treat patients with insomnia. Although CBTi has been efficacious in many patients, multitude of barriers for receiving treatment such as its limited availability of therapists, high costs and long wait times challenge its ability in sufficiently meeting the population's health needs and demands. To improve the delivery of CBT, electronically delivered CBTi (e-CBTi) has been developed as an accessible and effective alternative intervention for improving sleep outcomes in patients with insomnia. While evidence suggest that e-CBTi is effective when compared to placebos/waitlist control, evidence comparing guided e-CBTi to pharmaceutical interventions is still insufficient and needs further exploration.
Background. Self-management support is a complementary approach to treatment that aims to educate participants on the nature of anxiety and to improve their strategies to manage symptoms and well-being, thus presenting the potential to enhance recovery, improve outcomes, reduce recurrence rates and lower health care costs. There is limited evidence to support the effectiveness of group self-management support for anxiety disorders in community-based care. Objectives. This study aims at examining the effectiveness of a virtual group self-management support program (SMS) for anxiety disorders as an add-on to treatment-as-usual (TAU) in community-based care settings. We will also assess the incremental cost/effectiveness ratio and the implementability of the intervention. Methods. The trial is a pragmatic randomized controlled trial with a pre-treatment, post-treatment (4-month post-randomization), and follow-ups at 8, 12 and 24-months. Intervention. The experimental condition will consist of a 10-week SMS program for anxiety disorders in addition to TAU. The control condition will receive TAU without restrictions for anxiety disorders. Inclusion criteria will comprise being 18 years old or older, French-speaking, and presenting symptoms of anxiety disorders based on self-reported validated assessment scales. Patients will be recruited in the province of Quebec (Canada). Outcome measures: The primary outcome measure is the Beck Anxiety Inventory (BAI). The secondary outcome measures include self-reported instruments for anxiety and depressive symptoms, recovery, self-management, quality of life, and service utilisation. Statistical analysis: Intention-to-treat analysis. A mixed effects regression model will be used to account for between and within-subject variations in the analysis of the longitudinal effects of the intervention. Expected outcomes. The rigorous evaluation of the SMS intervention in the real world will provide information to decision makers, health care managers, clinicians and patients regarding the added value of group SMS for patients with anxiety disorders. Widespread implementation of this intervention could lead to more efficient mental health care services, to better long-term outcomes and to a significant reduction in the extensive social and economic burden of anxiety disorders.
Exercise is well-known to improve skeletal muscle energy metabolism and is an established intervention to improve muscle insulin sensitivity and to counter the development of type 2 diabetes (T2D). However, given the 24h rhythmicity in substrate metabolism previously observed in healthy, lean men and the lack of such rhythmicity in men with insulin-resistance, the investigator hypothesize that appropriate timing of exercise training can maximize the metabolic health effects of exercise. Indeed, a preliminary study in humans revealed that afternoon high-intensity interval training (HIIT) exercise was more effective than morning exercise in improving 24h blood glucose levels in men with T2D. Another recent study in mice showed that the time of day is a critical factor in augmenting the beneficial effects of exercise on the skeletal muscle metabolome as well as on whole-body energy homeostasis. However, human studies that specifically target the impact of timing of exercise training on glucose homeostasis and metabolic health are scarce and the potential underlying mechanisms largely unknown. The overarching goals of this project is to improve 24-hour rhythmicity of metabolism in men and women with prediabtes by appropriate timing of exercise and to assess its effect on metabolic health and immune response. Acute and prolonged exercise interventions timed in the morning vs late afternoon will be carried out in individuals with prediabetes to determine whether acute exercise in the afternoon and prolonged exercise training in the afternoon can improve peripheral insulin sensitivity, compared to exercise in the morning, and positively affect adipose tissue dietary fatty acid storage and partitioning of dietary fatty acids in skeletal muscles.
Participants will be asked to fill out an online questionnaire about their demographics information and all 42 items from the Depression Anxiety Stress Scale (DASS-42). A series of machine learning techniques will be applied to the dataset to develop a shortened assessment using the most important demographics and DASS-42 items from the original questionnaire, to predict depression levels indicated by DASS-42.
This double-blind, double-dummy study will evaluate the safety and efficacy of ocrelizumab compared with fingolimod in children and adolescents with relapsing-remitting multiple sclerosis aged between 10 and < 18 years over a duration of at least 96 weeks.
This prospective, randomized, placebo-controlled, double-blind study will be conducted to assess the efficacy of 2 billion CFU/day of B. coagulans Unique IS2 on improving bowel movement characteristics, gastrointestinal-related symptoms and quality of life in healthy adult participants who are experiencing more than 3.0 but less than 6.0 complete spontaneous bowel movements (CSBM) per week on average. Following a run-in period of 14 days to assess participants' baseline bowel habits, they are randomized to either B. coagulans or placebo for one month. The primary endpoint is change from baseline at 4 weeks in stool frequency in the test product group compared to the placebo group for average number of daily bowel movements over the week prior to the study visits. Secondary endpoints are stool frequency at weeks 1, 2, 3, stool quality measured by Bristol stool type scores, and gastrointestinal quality of life index (GIQLI) scores and subcategories (social, physical, emotional, symptoms).
