This study aims to investigate the optimal oxygen flow rate needed during tracheal intubation with the C-MAC video laryngoscope (Karl Storz, Tuttlingen, Germany) using Miller-blade or Macintosh-blade size No. 0 or No. 1 in the operating room or intensive care unit. The investigators hypothesize that the difference between low-flow and high-flow supplemental oxygen is negligible.

The purpose of the study is to evaluate the clinical performance of a new Negative Pressure Wound Therapy dressing in the management of chronic and acute wounds.

Despite decades of research, the pathogenesis of human diabetic kidney disease remains largely unclear. Our goal is to use archived human kidney biopsy tissue from patients with and with diabetic nephropathy to identify new molecules that drive and/or protect against disease progression. We will use RNA sequencing to identify transcriptomic changes that associate with histologic and functional outcomes.

Psilocybin, the chemical component of "magic mushrooms", has been administered with psychotherapy in several randomized clinical trials (RCTs) showing large and sustained antidepressant effects. In healthy volunteers, the psychedelic effects of psilocybin have been shown to be blocked by administration of serotonin (5HT)2A receptor antagonists such as risperidone. The purpose of this "double dummy" proof-of-concept trial is to evaluate whether psilocybin's antidepressant effects are dependent on its psychedelic effects. Sixty participants with treatment-resistant depression will be randomly assigned to one of three groups: 1) Psilocybin 25 mg plus risperidone 1 mg; 2) Psilocybin 25 mg plus placebo; and 3) Placebo plus risperidone 1 mg. The investigator's hypothesize that the combination of psilocybin and risperidone will be well tolerated, safe, and will block the psychedelic effects of psilocybin in patients diagnosed with treatment-resistant depression.

Corneal melt is a complication that could affect very ill eyes and lead to the thinning of the cornea (the clear window covering of the eyes). This thinning can lead to severe consequences such as the leakage of the liquid inside the eye (ocular perforation), or even blindness. Corneal melt can be caused by certain infections or as a sterile process. This project only includes patients with a sterile corneal melt (without an infection) caused by diseases such as rosacea, Sjogren's syndrome, rheumatoid arthritis, Crohn's disease, Stevens Johnson syndrome, as well as toxic epidermal necrolysis or mucous membrane pemphigoid. Infliximab is an antibody against tumour necrosis factor alpha and has been used to treat or prevent corneal melt in certain patients with inflammatory of auto-immune disease. In this situation, infliximab was used intravenous (using veins) in order to treat the whole body. This study's hypothesis is that infliximab can safely be used as eye drops for the treatment of sterile corneal melt.

Two of the major features of schizophrenia spectrum illness, negative and cognitive symptoms, have been associated with poor functional outcome and burden of illness. Given the proposed role of dopaminergic hypoactivity, augmentation with psychostimulants has been postulated as one of the potential treatment options for negative and/or cognitive symptoms of schizophrenia. The major drawback for use of these agents is a potential risk of relapse or worsening of psychosis through direct or indirect dopamine agonism activity and a great deal of caution has been called for use of stimulants in individuals with psychosis. However, preliminary results of earlier studies indicated improvement of negative and cognitive symptoms with off-label use of adjunctive psychostimulants. The present study aims to assess off-label use of adjunct psychostimulants in patients with schizophrenia in a tertiary mental health centre, focusing on efficacy and safety.

The use of a lumbar brace following single-level lumbar fusion for degenerative spondylosis (non-traumatic) is variable between surgeons. Some surgeons prefer to prescribe a brace and others do not. There is a lack of guidelines and evidence to support either treatment option. The purpose of this study is to assess feasibility and collect preliminary data to conduct a larger, definitive trial to provide evidence as to whether prescribing a brace or not results in better or equal outcomes. Imaging by CT scan, one year after surgery, will be used to analyze bone fusion (healing), and functional and pain scores from patients during their recovery will be compared to identify differences between patients who wore a brace and those who did not.

Infants born preterm can spend months in the neonatal intensive care unit (NICU) where they experience stressful but essential procedures. Untreated stress is associated with altered brain development. Skin-to-skin care (SSC) is one of the most effective behavioral strategies for mitigating preterm infant stress and improving brain maturation. However, parents may not be always available to provide SSC; some infants cannot be held for long periods for medical reasons. To address this problem, investigators designed Calmer, a patented, prototype therapy bed, for reducing stress in preterm infants. Calmer fits into NICU incubators and provides simultaneously an artificial skin surface, heartbeat sounds and breathing motion, mimicking aspects of SSC; the latter 2 features are individualized for each infant based on their parents' recordings. The 1st randomized controlled trial (RCT) in 58 preterm babies showed that during a routine blood test: Calmer lowered infant behavioral and heart stress responses and stabilized brain blood flow no differently than facilitated tucking; infants could be cared for safely on Calmer up to 6 hours in 1 day; Calmer was well accepted by mothers and staff. The goal now is to determine the efficacy of Calmer use over 3 weeks to support optimal physical growth and brain development in preterm infants. A 2-group (treatment, control) pilot RCT to test the implementation of an increased "dose" of Calmer exposure over 2-3 continuous weeks is proposed. 30 infants born between 26-30 weeks gestational age in the NICU will be randomized to receive either Calmer, for a minimum of 3 hours in total/day for 2-3 continuous weeks, or to 2-3 weeks of standard NICU care (minimum of 2 and maximum of 3 weeks). Research questions: Trial feasibility Q1. Is it feasible to enrol 30 infants, complete a 2-3-week treatment period (minimum of 2 and maximum of 3 weeks), and measure growth outcomes in preterm infants (26-30 weeks GA) in the NICU in a pilot RCT of daily Calmer treatment versus standard NICU care to inform a larger, definitive RCT? Infant outcomes Q2a. Are there differences in physical growth markers (daily weight gain, head circumference, body length) between preterm infants who receive Calmer and those who receive standard NICU care measured before (baseline) and after 2-3 weeks of daily Calmer exposure? Q2b. Are there differences in brain activity markers, as measured by cerebral electrical (EEG) signalling, between preterm infants who receive Calmer and those who receive standard NICU care, measured during a resting/sleeping state and routine diaper change session at the end of the trial (post 2-3 weeks of daily Calmer exposure)?

The purpose of this study is to evaluate the efficacy and cost-effectiveness of Breaking Free Online, in a comparison of outpatients seeking treatment for substance use disorder who receive standard care with group peer support, versus with access to Breaking Free Online, versus with access to Breaking Free Online and individual peer support.

H17-02904 is a randomized comparison of low dose rate vs. high dose rate prostate brachytherapy for favorable and intermediate risk prostate cancer suitable for brachytherapy as monotherapy. This is a continuation with expanded accrual of the randomized Pilot study H15-02103
