NCT ID: NCT04846660 Recruiting - Time Pressure Clinical Trials

Impact of Production Pressure in the Block Room on Patient Safety

Start date: March 20, 2021
Phase: N/A
Study type: Interventional

This randomized, single blinded simulation based study investigates the impact that production pressure can have on the safety of patients undergoing regional anesthesia. We created a high fidelity scenario where anesthesiologists and trainees were to perform a single shot infraclavicular ultrasound guided block. Participants were randomly assigned to the intervention or control group. Participants assigned to the intervention group were exposed to various production pressure generating interventions. The goal of this study was to look at the impact of production pressure on patient safety by scoring anesthesiologists' and trainees' performance and examining the differences between the two groups.

NCT ID: NCT04846530 Not yet recruiting - Histology Clinical Trials

Teosyal RHA® Histology and Intradermal Implantation Evaluation Study

Start date: April 23, 2021
Study type: Observational

The Teosyal RHA® family of products (RHA® 1, RHA® 2, RHA® 3, and RHA® 4) is approved in Canada for the correction of facial wrinkles and folds. In this study, the approved products will be placed in small boluses (0.2 mL) intradermally to allow for punch biopsies of the post-auricular space to be taken. The biopsies will include the injected material and surrounding skin tissue. Biopsies will be taken immediately after implantation of the product and at Day 30 and assessed by an independent blinded pathologist.

NCT ID: NCT04844138 Not yet recruiting - Clinical trials for Perinatal Depression

Evaluating Overcoming Anxiety in Pregnancy and Postpartum as an Online Self-Directed Program

Start date: April 7, 2021
Phase: N/A
Study type: Interventional

The pregnancy and postpartum periods can be joyous times in life; however, they can also be filled with challenging physical, emotional, and lifestyle changes. These changes may lead to feelings of stress, anxiety, and depression amongst new and expecting mothers, which can have negative effects on fetal and infant development (Beijers et al., 2010; Goodman et al., 2016). The impacts of increased worry about health and safety due to COVID-19 as well as future-related uncertainties, paired with social (physical) distancing, may be felt especially strongly in this population. Of concern, pregnant and postpartum women have low rates of mental health service use even prior to the pandemic (Fonseca et al., 2015). E-health (Internet) and m-health (mobile application) psychological interventions are accessible, available at reduced cost, and can be accessed within users' homes, a factor that is particularly important during the pandemic (Andrews & Titov, 2010). In this study, the investigators will disseminate a free, online, self-directed Cognitive Behavioural Therapy program to women experiencing symptoms of anxiety during pregnancy and postpartum. This program has shown to be effective at improving symptoms of anxiety and depression when delivered in an in-person group format, and has high acceptability (Furer & Reynolds, 2015). The investigators will transfer this program into an online format so that pregnant and postpartum users can navigate the sessions on their own, without the support of a clinician. This program contains six modules which include topics such as coping with negative thoughts, unpacking the myth of the supermom, and managing expectations during pregnancy and postpartum. Additionally, material related to COVID-19 has been added to the program to target any pandemic-related stress participants may be experiencing. The investigators will collect information about the program's feasibility, acceptability, and effectiveness, which will inform future improvements to the program. This program is expected to reduce participants' feelings of stress, anxiety, and depression, in addition to improving maternal attachment. It is anticipated that these gains will be maintained when the investigators follow-up with participants one month after program completion. This program has the potential to provide accessible and affordable mental health services to pregnant and postpartum women struggling during the pandemic.

NCT ID: NCT04843969 Active, not recruiting - Cigarette Smoking Clinical Trials

Investigation of Cigarette Cravings in Smokers

Start date: February 20, 2018
Phase: N/A
Study type: Interventional

Interventions to disrupt memory reconsolidation have held promise for the treatment of stress- and anxiety-related disorders. In the present study, the investigators will examine whether an intervention based on these principles, called memory updating, could be adapted for reward-seeking behaviors. To test this, non-treatment seeking tobacco smokers will be exposed to smoking cues and/or stress, two stimuli known to trigger smoking. It is predicted that exposure to a stress task will enhance the cues' motivational salience and yield greater susceptibility to the memory updating procedure. As an add-on, the investigators will examine COVID-associated changes in substance use and whether participants in the memory updating groups might be more resilient to these effects. It is predicted that the changes in substance use will depend on whether the substances are used primarily in social settings.

NCT ID: NCT04843800 Not yet recruiting - Low Back Pain Clinical Trials

Ultrasound of the Thoracolumbar Fascia for Diagnosing Chronic Low Back Pain

Start date: September 2021
Phase: N/A
Study type: Interventional

It is estimated that 23% of Quebecers suffer from chronic low back pain, and that 12% are disabled by this condition. Despite medical advances, the origin of so-called 'nonspecific low back pain' remains enigmatic. Conventional imaging methods by computed tomography and magnetic resonance may provide information on vertebral structures. However, very often, they do not diagnose lesions that genuinely correlate with the patient's symptoms. The lack of accurate diagnosis limits the therapeutic management in these patients. Therefore, patients are increasingly turning to alternative and complementary medicine therapies (e.g., acupuncture, chiropractic , osteopathy, shiatsu) to relieve their pain. These therapies target painful areas of abnormal hardening in muscles of the lower back and aim to release the tension in these tissues to control pain. However, these painful areas and their resolution after manual therapy have yet to be demonstrated by means other than manual palpation. We will conduct a randomized controlled trial in chronic low back pain patients to examine the effects of acupuncture, chiropractic therapy and therapeutic massage on lower back muscular and connective tissues' physical properties using innovative ultrasound techniques.

NCT ID: NCT04843683 Not yet recruiting - Cardiac Arrhythmia Clinical Trials

StereoTactic Ablative RadioTherapy of Cardiac Arrhythmias (START-CA)

Start date: June 2021
Phase: N/A
Study type: Interventional

This is a prospective, single-center, phase II trial that will be monitoring the safety and efficacy of using stereotactic ablative radiotherapy (SBRT) to treat patients with a medical condition affecting heart rate and rhythm (refractory arrhythmias) within the University Health Network (Princess Margaret Cancer Centre and Toronto General Hospital). The primary objective will be to prospectively monitor patient cardiac outcomes following SBRT.

NCT ID: NCT04843423 Not yet recruiting - Clinical trials for Attention Deficit Hyperactivity Disorder

Adjunct Treatment With Cariprazine for Adults With Attention-deficit/Hyperactivity Disorder

Start date: May 3, 2021
Phase: Phase 4
Study type: Interventional

According to the Canadian ADHD Practice Guidelines, psychostimulants are the preferred treatment of attention-deficit/hyperactivity disorder (ADHD), especially for those that require urgent care. Specifically, long-acting psychostimulants are considered the gold-standard pharmacological treatment for ADHD. Using extended-release formulations, long-acting psychostimulants provide an extended duration of daily symptom relief in addition to overall reductions in ADHD symptoms that are maintained over time. In accordance with these guidelines, clinicians may combine psychostimulants with other medications when it is considered necessary. For complex cases, psychostimulants alone are often inadequate for improving the effects of ADHD and are therefore prescribed in conjunction with other medications. At low doses, antipsychotics have been considered appropriate adjunctive medications. Studies show that most adult cases with ADHD that were undiagnosed or untreated in childhood result in the need for adjunctive medication in adulthood to enhance the effects of the psychostimulant. As a result, it is hypothesized that adjunct treatment with a low dose of cariprazine, an atypical antipsychotic, will enhance the effectiveness of standard ADHD treatment with a long-acting psychostimulant in a subset of the ADHD population that achieved little to no response on psychostimulants alone.

NCT ID: NCT04843072 Not yet recruiting - Valve Heart Disease Clinical Trials

Balloon vs. Self Expanding Transcatheter Valve for Degenerated Bioprosthesis

Start date: May 2021
Phase: N/A
Study type: Interventional

Transcatheter aortic valve implantation (TAVI) serves a growing spectrum of patients with symptomatic severe aortic stenosis (AS). Approximately 80% of surgical aortic valve replacements is performed using a bioprosthesis1. Durability of surgical bioprostheses varies based on the patient's age at the moment of implantation, type and size etc2. TAVI has become the preferred treatment for degenerated aortic bioprostheses in elderly patients3. The median time since index surgical aortic valve replacement (SAVR) and for bioprosthetic valve degeneration is typically 8 - 10 years4-6. TAVI in this setting has proven to have equally favorable results as in native aortic valves7. Balloon expandable8 and self-expanding9 transcatheter heart valves (THV) can be used in a degenerated bioprosthesis and each have specific assets and limitations. TAVI in a failed bioprosthesis can cause coronary obstruction, THV migration, paravalvular leakage and prosthesis patient mismatch. The SAPIEN-3 / Ultra and EVOLUT R/Pro are the 2 most commonly used THV platforms in contemporary clinical practice including treatment of failing surgical aortic bioprostheses. Objective: To compare TAVI with EVOLUT R/Pro vs. SAPIEN-3 / Ultra in terms of device success. Study design: International multi-center randomized study with 1:1 randomization to TAVI with SAPIEN-3 / Ultra or Evolut R/Pro. Study population: 440 patients with a failing surgical aortic bioprosthesis (aortic stenosis with or without aortic regurgitation) and selected for transfemoral TAVI by heart-team consensus. Investigational intervention: Transfemoral TAVI with SAPIEN-3 / Ultra or Evolut R/PRO Main study parameters/endpoints: 1. Primary endpoint is device success at 30 days Defined by - Absence of procedural mortality AND - Correct positioning of a single prosthetic heart valve into the proper anatomical location AND - Intended performance of the prosthetic heart valve (no severe prosthesis- patient mismatch and mean aortic valve gradient < 20 mmHg or peak velocity < 3 m/s, AND no moderate or severe prosthetic valve regurgitation). Severe prosthesis patient mismatch is defined by effective orifice area (EOAi) ≤0.65 cm2/m2 2. Safety endpoint at 1 year defined by the composite of all-cause death, disabling stroke, rehospitalization for heart failure or valve related problems.

NCT ID: NCT04842942 Recruiting - Surgery Clinical Trials

The Safety and Feasibility of Transoral Endoscopic Thyroidectomy Vestibular Approach

Start date: December 1, 2019
Phase: Phase 1
Study type: Interventional

This is a single center, prospective case series designed to assess the safety and feasibility of TOETVA in a small cohort of patients at University Health Network Toronto. Included patients will undergo a TOETVA-procedure in stead of the standard open surgical procedure.

NCT ID: NCT04842721 Not yet recruiting - Covid19 Clinical Trials

Effect of Hypertonic Saturated Saline Mouth Rinse on Covid-19 Virus in Vivo.

Start date: July 2021
Phase: Phase 2
Study type: Interventional

Sars-Cov2 virus is transmitted through the respiratory route and by direct contact with contaminated surfaces and subsequent contact with nasal, oral or ocular mucosa. Many studies have found that the oral cavity and specifically the saliva may be a high-risk route for SARS-CoV-2 infection. Thus, strategies reducing salivary viral load could contribute to reduce the risk of transmission. Furthermore, studies have shown that SARS-CoV persists for two days in oral mucous membranes before its diffusion to the lower respiratory tract. This offers an interesting preventive and therapeutic window of opportunity for the control of this disease. In addition, Naso-pharyngeal viral load was linked with lung disease severity in a study of 12 patients with pneumonia.**. Some current studies around the world, as listed on, are testing the effect of some common mouth rinses/gargles on the Covid-19 viral load, including Chlorhexidine gluconate, Hydrogen peroxide Povidone Iodine, Saline (1.102% w/v, slightly hypertonic) and Alcohol. This study aims to test whether Prolonged Hypertonic Saline Mouth Rinse would reduce/eliminate*** the viral load in the Oro- Naso-Pharyngeal cavity, and could therefore be used as a strategy to reduce transmission risk in clinical and social settings. The investigator hypothesizes that COVID-19-positive participants who use Hypertonic Saline Prolonged Rinse treatment will have an reduction/elimination of their Covid viral load, will develop a negative Covid test 7 days after intervention completion and will improve their clinical symptoms, potentially reducing lung disease severity.
