Background/rationale While multiple disorders feature a Type 2 (T2) inflammation, triggers for T2 remains unknown. In Chronic Rhinosinusitis with Nasal Polyposis CRSwNP), a classic Type 2 disorder, dysfunction of the epithelial barrier is suggested by loss of epithelial cell differentiation, impaired response to wounding, and impairment of innate defense mechanisms. After unsuccessful attempts to describe T2 disorders solely by host genetic or environmental factors, the role of epigenetics in the modification of innate immune response and epithelial integrity appears an important unexplored mechanism for a novel appreciation of T2 disease. In addition, the investigators explore the possibility that these changes may be induced by viral pathogens. This concept has been supported by the recent observation that SARS-CoV-2 viral reduction measures resulted in a reduction of the frequency of respiratory viruses and a concomitant reduction in chronic airway disease, suggesting a role for viruses in T2 disease. Hypothesis The investigators believe T2 chronic rhinosinusitis (CRSwNP) involves epigenetic mechanisms where external factors, possibly viruses, contribute to disease via epigenetic manipulation and/or chronic viral infection. Objectives The investigators aim to identify epigenetic signatures associated with T2 CRS and explore the contribution of viruses. Method A robust methylation profiling with extensive coverage will be used for epigenome-wide association studies in T2 CRS patients assessing healthy subjects, CRS patients in remission, and diseased patients undergoing surgery. Moreover, advanced transcriptomic and metagenomic methods will identify gene expression profiles and viruses. This proposal also includes a cross-sectional study of patients undergoing surgery to assess transcriptomic patterns and epigenetics at the single-cell level. Expected outcome The investigators expect to identify epigenetic biomarkers and implicate several pathogenic viruses to open new targets for novel therapies.

Insomnia is a highly common, chronic disorder that is distressful for the patient but also for caregivers and can give rise to a heavy burden on the healthcare team. Sleeping aids like benzodiazepines and other sedatives (e.g., zolpidem, zopiclone) have been widely used to help treat insomnia. However, sleeping aids are also known to cause adverse drug reactions such as drowsiness and dizziness, that increases the risk of falls, driving impairment, visual impairment, cognitive impairment, and upon discontinuation may cause paradoxical rebound insomnia, delirium, and nightmares all of which exacerbate the initial insomnia. All of the negative aspects of sleeping aid use are exaggerated for older, frail adults. Some patients experience an early (young-age) onset dementia with a substantial component of insomnia. Due to the many risks associated with traditional sleeping aids they are often inappropriate in adults living with cognitive impairment and/or frailty. Lemborexant comes from a new class of medications for insomnia. Lemborexant is a dual orexin receptor antagonist that blocks the binding of wake-promoting neuropeptides orexin A and orexin B to their receptors orexin 1 receptor (OX1R) and orexin 2 receptor (OX2R), which is thought to suppress wake drive. Unlike other traditional sleeping aids, lemborexant has not shown to be significantly associated with driving impairment, rebound insomnia, or dependence/withdrawal symptoms. Also, in clinical trials it only rarely causes the types of adverse events associated with benzodiazepines and other traditional sedatives and is less often associated with discontinuations due to adverse events. While lemborexant is available on the Canadian market it is unclear how this medication will be tolerated by patients living with an early onset dementia. Understanding the effectiveness and tolerability of lemborexant will be helpful in an N of 1 trial to understand the details of effect and effectiveness in individual patients.

Lower urinary symptoms (LUTS) affect older men and their frequency and severity increase with age. According to Berry et al., the histological diagnosis of benign prostatic hyperplasia (BPH) increases from 25% in the group age between 40 to 49 years to 80% in the group age between 70 to 79 years (1). However, this hyperplasia can lead to a bladder outlet obstruction (BOO) secondary to benign prostatic enlargement (BPE), causing storage and voiding symptoms, associated with a considerable impairment of the quality of life (2). Surgical therapy of BPH has continuously evolved in recent years. The current gold standard for the endoscopic treatment of BPH is the transurethral resection of the prostate (TURP). Other innovative techniques were developed including Urolift, transurethral laser enucleation (holmium, thulium) and Aquablation therapy. One of the latest technologies for the management of BPH are Optilume BPH Catheter System (Optilume®, Urotronic Inc, Minneapolis, USA) and Rezum Water Vapor Therapy (Rezum System, Bostocn Scientific, Marlborough, MA). The purpose of the present study is to compare between patient experience, symptom relief and functional improvement when using the Optilume BPH Catheter System (Optilume®, Urotronic Inc, Minneapolis, USA) and Rezum Water Vapor Therapy (Rezum System, Boston Scientific, Marlborough, MA).

The goal of this study is to determine whether a randomized controlled trial using oropharyngeal exercises to treat sleep apnea is feasible. Continuous positive airway pressure (CPAP) is the standard therapy for Obstructive sleep apnea (OSA), but it is poorly tolerated by many patients. Oropharyngeal exercises (OPEs) which are commonly used by speech-language pathologists to improve oro-motor strength, may serve as a promising alternative approach. The main questions this study aims to answer are: * Is it feasible to use an oropharyngeal exercise protocol in patients with sleep apnea? * Will oropharyngeal exercises improve sleep apnea severity, daytime sleepiness, sleep quality, mood, workplace performance, and quality of life Participants will be randomized into a supervised OPE intervention arm vs. unsupervised OPE intervention arm vs. sham treatment for a 10-week/5-day per week/two 20-minute session exercise protocol. The exercises will be administered via an app and the investigators will assess feasibility, as well as several sleep-related and oro-motor physiological outcomes before treatment, immediately post-treatment, and 4 weeks post-treatment. The investigators will use the results of this feasibility trial to inform the sample size needed for a larger clinical trial that will determine the efficacy of using oropharyngeal exercises to treat OSA.

The goal of this randomized controlled trial is to evaluate the effectiveness of inhaled methoxyflurane (Penthrox) as an analgesic for patients undergoing minor rhinology and sinus procedures, specifically comparing it to a placebo control. The primary question the study aims to answer is: Does methoxyflurane provide superior pain relief compared to placebo during minor sinus procedures, as measured by the Visual Analog Scale (VAS)? If there is a comparison group: Researchers will compare the effects of Penthrox to the placebo (saline + one drop of methoxyflurane) to see if it provides better pain relief, reduces anxiety, and leads to fewer complications, including bleeding. Participants will be asked to: Inhale 3 mL of Penthrox or placebo during their procedure. Complete a VAS scale to assess pain. Complete anxiety assessments pre- and post-operatively. Be monitored for complications such as bleeding and other adverse effects. This study will help determine the effectiveness of Penthrox as a non-invasive, quick-acting analgesic for minor sinus surgeries.
