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 is a clinical trial. In Manitoba, the treatment of cervicofacial infections of odontogenic origin which require inpatient medical and surgical management by Oral and Maxillofacial Surgeons are treated in a reproducible and stepwise manner. After a standardized pre-operative diagnostic workup (including appropriate imaging, bloodwork, and pre-operative history and physical), these patients are taken to the operating room for appropriate surgical intervention (extraction of necessary teeth and incision/drainage of the associated abscess). These patients are then treated with a combination of antibiotics, steroids, and adjunctive medications as needed for supportive care until ready for discharge. Intravenous corticosteroids are frequently administered following dentoalveolar and maxillofacial surgery procedures to decrease post-operative edema, improve patient comfort, and thus hasten recovery time. Within the context of primary and deep space odontogenic infections, one of the major sources of morbidity is the mass effect produced by edema causing airway obstruction. Additionally, manipulation of the soft tissues during the surgical procedure(s) (incision and drainage, extraction of teeth, etc.) may result in increased swelling around the airway. Inflammation and spasm of the muscles of mastication is another sequelae of infection, which can result in severe trismus. The literature supports the use of intravenous corticosteroids as an adjunctive treatment in the management of primary and deep space neck infections, and thus corticosteroid use is within the standard of care. However, the glucocorticoid dosing regimen is currently determined by the clinical judgment of the attending surgeon. One commonly used regimen for steroid dosing is prescribing Solumedrol 125mg IV X1 dose at the time of surgery. Another commonly used regimen for steroid dosing is prescribing Solumedrol 125mg IV X1 dose at the time of surgery, followed by 3 consecutive doses of Solumedrol 125mg IV every 6 hours post-operatively. The goal of this study is to guide future decisions related to the treatment of patients with cervicofacial infections of odontogenic origin in Manitoba. This study is intended to follow the post-operative inpatient course of 30 patients with various cervicofacial infections of odontogenic origin. All will be treated via a standardized surgical protocol (incision/drainage and extraction of necessary teeth), antibiotics, and steroids. 15 patients will be randomly assigned to receive 1 dose of Solumedrol 125mg IV at the time of surgery but no doses following surgery. The remaining 15 patients will receive 1 dose of Solumedrol 125mg IV at the time of surgery plus 3 consecutive doses of Solumedrol 125mg IV every 6 hours post-operatively. In summary, the only impact of study involvement will be the determination of the intravenous glucocorticoid dosing schedule, as all patients will continue to receive the current standard of care (including surgical management, antibiotics, and intravenous corticosteroids). To ensure the preservation of the highest level of patient care, in the rare instance where an attending surgeon decides peri-operatively that the pre-determined steroid dosing regimen will result in unsatisfactory treatment, the randomized patient assignment will be abandoned, and alternative treatment regimens will be used under the guidance of the attending Oral and Maxillofacial Surgeon. Treatment will be undertaken at the Health Sciences Centre adult operating room and inpatient wards, the primary operating site for the University of Manitoba's attending on-call Oral and Maxillofacial Surgeons. The patient's post-operative course in hospital will be completed within the inpatient wards at the Health Sciences Centre, until the patients are deemed appropriate for discharge. Specific patient outcomes will be evaluated at the time of hospital admission, daily while admitted to hospital, and at the time of hospital discharge. Outcomes evaluated will include: - C reactive protein (CRP) levels (acute phase reactant which is a hematologic biomarker of inflammation) - White blood cell (WBC) levels (hematologic biomarker of infection) - Length of hospital admission (days) - Trismus (in mm) - Daily clinical examination findings (during morning inpatient rounds while admitted) This study poses no additional risks to the patients involved, as these patients would be receiving intravenous glucocorticoids whether they were enrolled in the study or not. There are standard risks of complications involved with both the surgical and pharmaceutical treatment of cervicofacial infections of odontogenic origin, and these risks are discussed with patients pre-operatively and prior to hospital admission to obtain informed written consent.
The COVID-19 pandemic is a public health concern; for which the WHO recommends protective measures and vaccination. There is inadequate data on the impact of COVID-19 vaccination and control measures in Africa. This survey is collecting data about people's knowledge, attitude and compliance regarding COVID-19 disease and vaccines.
Hip fractures are common in elderly patients, and require surgery. Many elderly patients take anticoagulants for vasculopathy treatment. Anticoagulation precludes the use of neuraxial anesthesia because of the risk of epidural bleeding. Caudal anesthesia may be a safe and effective technique in anticoagulated emergency surgical patients. Quantitative analysis of prospective clinical data. Evaluation of caudal anesthesia efficacy for hip fracture surgery. Analysis of perioperative outcome, and postoperative course.
The presence of solid food or fluid residue in the stomach is always a major concern when patients require medical procedures under sedation or general anesthesia, due to the high risk of pulmonary aspiration of the stomach contents. This is especially important in emergency procedures, when a fasting period could not be observed. Pulmonary aspiration of gastric content is a serious perioperative complication of obstetric anesthesia, and it is associated with morbidity and mortality. Information from a bedside ultrasound assessment of the stomach may be a very useful resource to decide whether it's safe to proceed, cancel or delay a surgical procedure. The ultrasound assessment of the stomach content has shown to be very feasible and practical in non-pregnant patients. However, it has not been determined whether the competence reached by anesthesiologists in non-pregnant subjects can be transferred to the obstetric population, especially in term pregnant patients where it could be difficult to identify the stomach because of the presence of the gravid uterus. Although quantitative assessment of the gastric antrum cross-sectional area in terms of intra- and interrater reliability has been evaluated in non-pregnant adults, it remains to be evaluated in pregnant patients. Furthermore, it has not been determined whether the performance of novice operators is comparable to expert operators in the gastric quantitative assessment. This study aims to determine whether trained anesthesiologists can reliably assess the stomach content of pregnant patients by ultrasound, evaluating the inter- and intra-rater reliability of quantitative gastric ultrasound in term pregnant patients comparing anesthesiologists of different level of expertise. The investigators hypothesize a substantial to almost perfect agreement in the intra- and interrater reliability of the antral cross-sectional area among raters in term pregnant patients scheduled for elective cesarean delivery.
Chronic Pain is one of the most common reasons adults seek medical care, and has been linked to restrictions in mobility and daily activities, dependence on opioids, anxiety and depression, and poor perceived health or reduced quality of life. Chronic Pain Clinics are an effective solution, however, the resources available and investments have fallen behind the growing needs of patients. Local waitlists have thousands of patients with wait times between 1 to 3 years, with many receiving little to no specialized support while waiting. Tools and technology that can help patients and healthcare providers understand and manage the patients' pain are needed for the effectiveness of the healthcare system. In response to this problem, the Manage My Pain (MMP) App, which allows patients to log daily reflections of functionality, pain, and medication use; as well as, provide educational resources is a potential support for patients on the waitlist. This log is intended to support the patient understanding and management of their pain, and share their reports with their circle of care. This study will assess the impact of MMP on waitlist patients' health outcomes compared to a control group of waitlist patients over 60 days.
The goal of this randomized crossover clinical trial is to determine if habitual sleeping habits can predict endurance performance following a night of partial sleep deprivation in healthy untrained, recreationally trained, and trained cyclists (18-50 years, ~50% females). The main questions it aims to answer are: 1. Can habitual sleeping habits predict, or do different types of sleepers alter, performance outcomes following sleep deprivation? 2. Does sleep deprivation alter blood pressure, heart rate, or metabolic responses during a 20-minute time trial, and/or are these altered amongst different types of sleepers? 3. Can habitual sleeping habits predict, or do different types of sleepers alter, flow-mediated dilation following a night of normal sleep and/or sleep deprivation? - Participants will be asked to perform 4 performance tests (20-minute time trial), 2 for familiarization, and 2 testing visits (1 under normal sleep and 1 under partial sleep deprivation). - For 1 week prior to each testing visit, sleep will be tracked using an ActiGraph device. - During each testing visit, and prior to the performance test, the vascular function of the superficial femoral artery will be assessed using a flow-mediated dilation technique. The investigators hypothesize that habitual early sleepers, poor sleepers, those with greater variability in sleep duration, and females will show the greatest impairments in performance and flow-mediated dilation following partial sleep deprivation.
The objective of the study is to compare the clinical performance of two monthly toric silicone hydrogel contact lenses in habitual wearers, when worn for 1-month each.
In the RELEVANCE study, we will develop a scalable electronic medical report data capture platform to collect and analyse real-world data in the stage III NSCLC population in Canada across several Canadian cancer centres. Subsequent analyses will examine treatment patterns and clinical outcomes, including overall survival, for these patients, stratified by durvalumab regimen or non-durvalumab regimen during the time of the PACIFIC Patient Support Program.
