There are about 28871 clinical studies being (or have been) conducted in Canada. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
This study will assess the efficacy, safety, and tolerability of elvitegravir/cobicistat/emtricitabine/tenofovir alafenamide (E/C/F/TAF) fixed-dose combination (FDC) in human immunodeficiency virus (HIV)/hepatitis B virus (HBV) coinfected adults. Participants will be enrolled into two cohorts: - Cohort 1: HIV/HBV coinfected adults who are HIV treatment-naive and HBV treatment-naive - Cohort 2: HIV/HBV coinfected adults who are HIV-suppressed
Study to evaluate if macitentan is safe and tolerable enough to be used for treatment of subjects with combined pre- and post-capillary pulmonary hypertension (CpcPH) due to left ventricular dysfunction.
This pilot study will test a new therapy, somatosensory rehabilitation, for the painful sensitivity experienced by persons with nerve injuries and/or complex regional pain syndrome (CRPS). Several methods for measuring pain and sensitivity that emphasize the person's evaluation of their own symptoms and the impact of these symptoms on their daily activities will also be tested to make sure they are consistent and accurate. Previous research has suggested one of the assessments may also be used to assist in the identification of CRPS: this simple test will be evaluated to see if it can accurately identify persons with this disorder (for which there is currently no diagnostic test). Together, this will improve treatment of CRPS through early, accurate diagnosis and the ability to measure important changes in this painful condition, and set up future studies for this new rehabilitation treatment method.
To acquire low radiation dose and good quality cardiac CT images requires scanning at low heart rates which is usually done with beta-blockers. However, in some patients beta-blockers have little effect. This is thought to be due to a different mechanism of action which continues to maintain the heart rate despite administration of beta-blockers. This study aims to look at the effect of music or relaxation tracks to reduce patient heart rate as anxiety is thought to play a role in maintaining high heart rates. This study will randomise patients into a normal standard of care group compared to a normal standard of care group with music/ relaxation track and compare heart rate, radiation dose, image quality, amount of beta-blocker used and patient experience via a State-Trait Anxiety Inventory (STAI) questionnaire.
Silent ischemic, also known as "covert stroke vascular disease" (CSVD), contributes to neurological deficits that are caused by damage to small blood vessels in the brain. CSVD occurs six to ten times more often that an acute stroke. It is misleading to think, however, that CSVD is an inevitable part of "getting old" because people with CSVD are at high risk of developing an acute stroke or dementia. In fact, people with more CSVD lesion volume are more likely to develop day to day problems in planning, decision-making and speed of thinking. Unfortunately, there are no proven therapies designed to address CSVD. We propose to test whether aerobic exercise is an intervention that can combat CSVD because the disease is fundamentally a blood flow problem that may be improved by aerobic exercise. We will recruit CSVD adults with moderate to severe lesion burden and use magnetic resonance imaging (MRI) to study the brain in terms of structure, perfusion and function. Participants will be randomly assigned to either our established aerobic exercise program or a control stretching program. Both groups will take part in lab exercise sessions, which are designed to monitor progress and assess adherence to the program. The duration and intensity of their exercise will increase as participants progress. We will use activity log books, phone calls and extra "booster" exercise sessions, as needed, to maximize retention and adherence. We aim to show that aerobic exercise increases cerebral blood flow (CBF) in frontal-subcortical grey matter, supports regional tissue growth, and improves cognitive function in CSVD adults with substantial risk of acute stroke and dementia. A positive outcome of this research will provide strong support for additional clinical trials aimed at sustaining cognition and maintaining independent living.
The limited research that exists suggests that lesbian, bisexual and queer (LBQ) women are at similar risk for sexually transmitted infections (STI) as heterosexual women. This is a particularly important area to address, as literature highlights the convergence of sexual stigma and gender-based sexual violence as elevating LBQ women's risk for HIV and STI infection. However, recent Statistics Canada data indicated that: lesbians reported significantly lower rates of Pap testing than heterosexual or bisexual women; lesbians and bisexual women had higher odds of not having a regular doctor than heterosexual women; and bisexual women had higher reported unmet health care needs than lesbian and heterosexual women. These differences highlight the importance of implementing and evaluating interventions to address STI risk among LBQ women; however, no published study exists of this nature. A STI prevention intervention will be implemented with groups of LBQ women and WSW in Toronto and Calgary. The study has 5 distinct components: 1) key informant interviews to inform the development of the intervention training manual and survey questionnaire, 2) pre-test; 3) intervention (6 group sessions during a weekend retreat); 4) post-test directly following intervention, and 5) follow-up post-tests at 6 and 12 weeks. The study hypothesis is that, compared to pre-intervention, participants who receive the group-based intervention will report an increase in sexually transmitted infections (STI) knowledge post-intervention. The secondary hypotheses are that, compared with pre-intervention, participants will demonstrate higher mean scores of (a) safer sex self-efficacy; (b) STI testing; (c) safer sex practices; (d) resilient coping, (e) self-esteem, (f) social provisions, (g) community connectedness and (h) access to health care. We anticipated that compared to pre-intervention, participants post-intervention would report lower mean scores of (a) depression and (b) internalized stigma.
Hardly any imaging studies specifically addressing the articular and periarticular structures in MPS patients are available at this point. The investigators propose to do for the first time a pilot study using musculoskeletal ultrasound in patients with various types of MPS.
Bariatric surgery induce remarkable weight loss and improvement or resolution of type 2 diabetes. Obesity is the primary risk factor for type 2 diabetes, and 90% of all type 2 diabetics are obese. Type 2 diabetes resolves post-operatively in 84-98% after bypass and 48-68% after restrictive procedures. Obesity leads to elevated plasma free fatty acids and subsequently to excessive accumulation of triglyceride in peripheral tissues, which is an independent risk factor for insulin resistance and type 2 diabetes. Bariatric surgery is associated with dramatic decrease in plasma free fatty acids and other lipids. This study will clarify the relationship of changes in fatty acid and other lipid metabolism to improved insulin sensitivity after different bariatric procedures ('restrictive' - laparoscopic adjustable gastric band and 'hybrid' - laparoscopic roux-en-y gastric bypass) and compare them with non-surgical obese patients. This will allow the investigators to refine indications for these procedures especially in patients with type 2 diabetes. The investigators will analyze whether surgical bypass of the upper small bowel plays a critical role in the resolution of type 2 diabetes and improvement in lipid metabolism. The investigators will achieve this by comparing gastric banding and gastric bypass in a collaborative research study involving obesity surgeons, physicians and lipid researchers.
The main objective of the study is to test the feasibility of the ICU diaries intervention in the ICU. The investigators do not have sufficient power to detect differences in the hypotheses below, but will use the present pilot study to inform sample size required to adequately power a follow-up randomized control trial. (1) The investigators hypothesize that subjects exposed to a psychoeducation condition will have reduced rates of post-traumatic stress disorder (PTSD) compared to those experiencing treatment as usual (TAU). (2) The investigators hypothesize that compared to participants in the psychoeducation and TAU groups, those subjects exposed to an ICU diary, and those exposed to both ICU diary + psychoeducation conditions, will have significantly reduced rates of PTSD at follow-up. (3)The investigators hypothesize that participants exposed to the ICU diary + psychoeducation condition will have significantly lower rates of PTSD compared to those in the ICU diary alone condition.
Pressure support (PS) is a commonly used mode of ventilation which is triggered based upon the patient's own inspiratory efforts. For the most part, pressure support is well tolerated by patients. However, because the trigger for pressure support is an inspiratory effort by the patient, and because the resulting support is constant, the ventilator response can be "out of sync" with the patient's needs. The problem of patient-ventilator asynchrony has been documented to be large in approximately one quarter of patients who require mechanical ventilation. Asynchrony is associated with increased or abnormal work of breathing (WOB) and prolonged duration of mechanical ventilation. Diagnosing asynchrony at the bedside can be challenging. Electrical activation of the diaphragm (Eadi) recording can provide clinicians with a more accurate picture of patient-ventilator synchrony and may thus result in decreased asynchrony and decreased or normalized work of breathing for the patient. The purpose of this physiologic study is to evaluate the role of protocolized pressure support ventilation (based upon Eadi) in comparison to standard pressure support ventilation.
