NCT04066075
The successful application of magnification devices for reading and daily tasks is predicated on their correct use by individuals with low vision (LV). Barriers related to transportation, geography, and/or co-morbidities often limit LV patients' ability to attend several in-office training sessions as part of low vision rehabilitation (LVR) to optimize visual function with magnification devices. A promising solution is real-time videoconferencing to provide telerehabilitation, involving remotely delivered LVR services by a LVR provider in office to a patient at home. Telerehabilitation for LV appears to be feasible and acceptable by both patients and LVR providers, yet there are no published outcomes on the potential to improve patients' visual functioning. Another key issue in LVR is the need for an effective system to continually assess how patients are functioning at home. Ideally this would involve a non-invasive, efficient method to assess when magnifier device abandonment occurs, so that a timely telerehabilitation session can be initiated. Small Bluetooth low energy beacon sensors attached to the handles of magnifiers can collect real-time data regarding minute-to-minute environmental changes, which might serve as an indicator of magnifier use by LV patients at home. Specifically, the investigators propose to assess the potential for telerehabilitation to enhance visual function by providing remotely-delivered LVR training to use magnification devices. Following one in-office training session for new magnification device(s), the investigators aim to determine if there is additional gain in visual functioning by randomizing subjects to telerehabilitation or additional in-office LVR (active control). Participants will be assessed before and after two consecutive periods: (1) one month after a single LVR training session, followed by (2) up to three LVR sessions over a three month period either via telerehabilitation in the participants' homes or LVR in-office. The investigators will determine which patient characteristics and/or magnification devices are most likely to benefit from telerehabilitation. The investigators will also determine whether data from Bluetooth beacon sensors are valid indicators of hand-held magnifier device usage by LV patients at home. The study investigators will deploy Estimote Sticker beacon sensors to subjects randomized to telerehabilitation or additional in-office LVR during the same study period. It is anticipated that beacon sensors will measure significantly increased temperature and/or motion when placed on the part of the magnification device held by LV patients while performing daily activities. Beacon sensor data will determine if it is feasible to assess when magnification devices are used, and if the frequency of magnifier use changes following telerehabilitation or in-office LVR. This work will evaluate and refine the procedures for implementing these technologies for LVR, in order to develop future randomized controlled trial protocols. The investigators envision that telerehabilitation and beacon sensors could improve LV patient outcomes by providing follow-up LVR services in a more efficient and timely manner.

NCT04855396
There are no therapeutic agents that have been shown to improve outcomes from severe traumatic brain injury (TBI). Critical barriers to progress in developing treatments for severe TBI are the lack of: 1) monitoring biomarkers for assessing individual patient response to treatment; 2) predictive biomarkers for identifying patients likely to benefit from a promising intervention. Currently, clinical examination remains the fundamental tool for monitoring severe TBI patients and for subject selection in clinical trials. However, these patients are typically intubated and sedated, limiting the utility of clinical examinations. Validated monitoring and predictive biomarkers will allow titration of the dose of promising therapeutics to individual subject response, as well as make clinical trials more efficient by enabling the enrollment of subjects likely to benefit. Glial fibrillary acidic protein (GFAP), neurofilament light chain (NfL) and high sensitivity c-reactive protein (hsCRP) are promising biomarkers that may be useful as 1) monitoring biomarkers; 2) predictive biomarkers in severe TBI trials. Although the biological rationale supporting their use is strong, significant knowledge gaps remain. To address these gaps in knowledge, we propose an ancillary observational study leveraging an ongoing severe TBI clinical trial that is not funded to collect biospecimen. The Hyperbaric Oxygen in Brain Injury Treatment (HOBIT) trial, a phase II randomized control clinical trial that seeks to determine the dose of hyperbaric oxygen therapy (HBOT) that that has the highest likelihood of demonstrating efficacy in a phase III trial. The proposed study will: 1) validate the accuracy of candidate monitoring biomarkers for predicting clinical outcome; 2) determine the treatment effect of different doses of HBOT on candidate monitoring biomarkers; and 3) determine whether there is a biomarker defined subset of severe TBI that responds favorably to HBOT. This proposal will: 1) inform a go/no-go decision for a phase III trial of HBOT by providing adjunctive evidence of the effect of HBOT on key biological pathways through which HBOT is hypothesized to affect outcome; 2) provide evidence to support further study of the first monitoring biomarkers of severe TBI; 3) increase the likelihood of success of a phase III trial by identifying the sub-population of severe TBI likely to benefit from HBOT; 4) create a repository of TBI biospecimen which may be accessed by other investigators. This study is related to NCT04565119

NCT06463314
To help reach the undiagnosed living with HIV and/or syphilis in Canada, point-of-care (POC) tests for HIV and Syphilis may have substantial utility for increased identification of infected individuals through their relative ease of use and portability, as well as their ability to deliver rapid, actionable results while the care provider still has access to the patient. MedMira Inc. (Halifax, NS, Canada), has developed a POC test to detect HIV and Syphilis antibodies in fingerstick blood samples that is seeking approval from Health Canada for use by trained healthcare professionals. The goal of this study is to provide evidence that untrained, non-registered health care providers (ie. peer testers) can perform the test without any increased risk of obtaining erroneous results. This test requires no instrumentation and can be used by non-registered health care professionals including peer testers ("Operators") in multiple near patient settings such as community health centres and point of care testing locations.
NCT05966155
This study is comprised of three separate pharmacogenetic trials grouped into a single protocol due to similarities in the intervention, the hypotheses, and the trial design. The three trials are the Acute Pain Trial, the Chronic Pain Trial, and the Depression Trial. Participants can enroll in only one of the three trials. All three trials were registered on ClinicalTrials.gov under NCT04445792. In July 2023 each of the three treatment trials was registered under a separate NCT# and NCT04445792 was converted to a screening record per recent guidance on master protocol research programs (MPRPs). This record is specific to the Depression Trial within the ADOPT-PGx protocol. The Depression Trial is a prospective, multicenter, two arm randomized pragmatic trial. Participants meeting eligibility criteria will be randomly assigned to either immediate pharmacogenetic testing and genotype-guided anti-depressant therapy (Intervention arm) or standard care with 6-month delayed pharmacogenetic testing (Control arm). The investigators will test the hypothesis that pharmacogenetic testing and genotype-guided anti-depressant therapy will reduce depression symptoms in participants who's body processes some anti-depressants faster or slower than normal.

Researchers want to better understand what happens to the heart when the autologous (from one's own body) stem cells are injected directly into muscle of the right side of the heart during the Fontan (Stage III) surgery. They want to see if there are changes in the electrical activity, the structure, and the function of the heart following this stem cell-based therapy. Researchers will compare the results from people who receive the stem cells to the results from people who do not receive the stem cells.
NCT06179485
The RSI-LTO study collects long-term outcomes from the RSI trial (NCT05277896). One-third of adults who are intubated in the ED or ICU experience symptoms of posttraumatic stress disorder (PTSD). PTSD is a psychiatric disorder triggered by a "shocking, scary, or dangerous event." Critical illness, tracheal intubation, and mechanical ventilation can be traumatic and distressing events. Patients may recall the intubation procedure, the feeling of the breathing tube in their throat, or being unable to move ("paralyzed"). While on the breathing machine, patients may experience delirium, frightening hallucinations, and delusions. Patients with PTSD after critical illness can be hypervigilant, anxious, and troubled by intrusive thoughts, nightmares, and flashbacks that last months to years after critical illness and that PTSD negatively impacts patients' marriages, work, and quality of life and increases patients' risk of depression, anxiety, substance use disorder, and suicide. Ketamine may prevent PTSD symptoms by blocking the pathways in the brain's glutaminergic system that are responsible for the formation of traumatic memories In outpatients with chronic PTSD, a single dose of ketamine has been shown to reduce PTSD symptoms for up to 2 weeks. Even a modest reduction in PTSD would translate into tens of thousands of fewer cases of PTSD each year, more cases of PTSD each year than any other medical intervention evaluated to date.
NCT04715646
The purpose of the study is to evaluate the long-term safety and tolerability of brivaracetam.
NCT05566431
Narrative: Worldwide, traumatic brain injury (TBI) is a leading cause of death and disability among children and adolescents. The Investigators aim to test whether pediatric TBI treatment guided by invasive intracranial pressure monitoring produces better patient outcomes than care guided by a protocol without invasive monitoring. Study findings will inform clinical practice in treating pediatric severe TBI globally. Focused didactic and experience-based learning opportunities will increase the research capacity of pediatric intensivists in Latin America.
