Little is known about the factors that cause biliary atresia nor the factors that influence disease progression. The purpose of this study is to collect the pertinent clinical information, genetic material and body fluid samples to enable investigators to address the following aims: To identify the gene or genes implicated in the etiology of BA; To identify polymorphisms that may be important in disease progression such as HLA polymorphisms; To characterize the natural history of the older, non-transplanted child with BA.

Primary sclerosing cholangitis (PSC) is a rare liver disease that damages the liver's bile ducts. Bile ducts are tiny tubes that carry bile from the liver to the small intestine. Bile is a liquid produced by the liver that helps us absorb and use the nutrients in the food we eat. In people with PSC, the bile backs up into the liver and will damage it, causing scarring of the liver. The purposes of this study are to: * Collect medical and other data to learn more about PSC, how it progresses, and identify factors that may cause the disease to progress more quickly. * Ask questions about how PSC symptoms affect your child's life to learn more about its impact on your child's daily functioning * Children with PSC who are seen at one of the participating clinical sites in the Childhood Liver Disease Research Network (ChiLDReN) will be asked to contribute information, DNA, and other specimens. The information and specimens will be available to investigators to carry out approved research aimed at learning more about the possible causes and long-term effects of PSC. Read Less

Radiotherapy (RT) is common in the treatment of breast cancer, however, 95% of breast cancer patients are at risk of developing acute and chronic skin toxicities known as radiation dermatitis (RD) which includes symptoms such as pruritus, edema, erythema, and moist desquamation (MD). Patients with a larger breast size are especially at risk of developing RD. The severity of RD can impact patient's quality of life (QOL) and their ability to complete treatment. Skin care guidelines for patients receiving RT vary and include barrier films and dressings, antibiotics, topical corticosteroids, and moisturizers. A study conducted at the Sunnybrook Odette Cancer Centre investigated the effectiveness of the prone treatment position during RT compared to the supine position. The results indicated that the prone position reduced the incidence of MD from 39.6% in supine to 26.9% in prone. However, 1 in 4 patients in the prone position still develop MD. Another study conducted at Sunnybrook Odette Cancer Centre found that Mepitel Film (MF), a barrier film, is more effective than the standard of care in preventing grade 2 or 3 RD, reducing the incidence of grade 2 or 3 RD from 45% to 15%. Despite its effectiveness, MF cannot be used for patients in the prone position and is costly. The topical corticosteroid betamethasone can prevent skin toxicity through its anti-inflammatory properties and is absorbed by the skin with minimal side effects. Betamethasone is cost-efficient and studies have found that it is effective in reducing the severity of RD in the supine position by half. Moreover, betamethasone can be applied in patients positioned in both prone and supine. The investigators hypothesize that adding betamethasone in large-breasted patients treated in prone during RT will further reduce RD. This randomized control trial is the first of its kind to aim at investigating the effectiveness of betamethasone when compared with the standard of care in reducing the severity of RD in large-breasted patients being treated in the prone position during RT. The investigators will enroll 276 breast cancer patients with band size ≥ 40 or ≥ D cup to be randomized to receive 0.1% betamethasone cream or the standard of care in a 2:1 ratio (alpha = 5% and power = 80% with the hypothesis that the addition of betamethasone to prone reduces the severity of RD from 30% to 15%). Upon enrolment, stratification factors will be recorded, and patients will be randomized into trial arms using procedures that balance stratification factors. All eligible patients will be stratified according to the following factors: patients receiving conventional RT (50Gy/25#) versus hypofractionated RT (40Gy/15#) versus extreme-hypofractionated RT (26Gy/5#), whole or partial breast radiation, patients with Fitzpatrick skin type VI versus patients with Fitzpatrick skin type I-V, patients receiving a planned boost versus patients without planned boost. The CRA will be responsible for collection of assessments and photos from patients. Patients will use the assigned cream daily during RT treatment and up until 2 weeks after RT. The primary endpoint of this study is acute grade 2 or 3 toxicities as defined by the Common Terminology Criteria for Adverse Events v5.0. Secondary endpoints will include patient- and clinician-reported outcomes as assessed by the Skin Symptom Assessment and the Radiation-Induced Skin Reaction Assessment Scale. Moreover, the investigators will also employ a QOL tool, the Skindex-16, and a Patient Satisfaction Questionnaire. Patients will complete assessments weekly during RT and 2 weeks post-RT in person, followed by 6 weekly assessments and a 3-month telephone follow-up post-RT. Clinicians will assess patients weekly during RT and at the 2-week follow-up appointment. Read Less

Our research group has found that Canadians with undiagnosed asthma or chronic obstructive pulmonary disease (COPD) have increased respiratory symptoms and worse health-related quality of life. The investigators recently developed and validated an on-line questionnaire to accurately identify these symptomatic, undiagnosed individuals. The investigators will advertise in the community asking individuals to complete the on-line questionnaire at home, at their leisure, to determine if they are at risk of asthma or COPD. Those at risk will be invited to participate in a randomized, controlled clinical trial to determine whether early diagnosis of previously undiagnosed asthma or COPD and subsequent treatment by the primary care practitioner will improve their quality of life.

The RECRUIT study is a multinational, multicenter physiological observational study conducted by the PLUG working group. It is a single-day study (1.5-2 hours) associated with specific lung (de)recruitment maneuvers to verify the feasibility of measuring the potential for lung recruitment in mechanically ventilated patients with ARDS by electrical impedance tomography (EIT).

The goal of this clinical trial is to assess the effectiveness of a sound-based passive treatment for reducing stress and annoyance induced by tinnitus, and how this therapy may improve tinnitus sufferers' quality of life. The main questions it aims to answer are: • \[question 1: to assess the efficacy of the LUCID/VIBE in managing the tinnitus handicap (measured by the reducing of the annoyance/stress response to tinnitus) contributing to the improvement of the quality of life of people living with tinnitus\] and • \[question 2: assess the efficacy of LUCID/VIBE in providing temporary relief through masking, such that it results in a reduction of the perceived loudness of tinnitus\]. Participants will \[use the VIBE app for 24 minutes a day for a period of 4 weeks. There will be two conditions, a Noise condition (the control condition in which the investigator will administer white noise) and the VIBE condition (the treatment condition). One approach involves broad-band masking with noise (Noise Condition), while the other uses music (LUCID Condition). Implementation of the noise condition will mirror the LUCID condition in terms of ease of access, look, feel, so that one condition does not look less professional than the other. Both conditions will be administered through the same app, and only the sound conditions will differ (white noise vs. LUCID music). All participants will be exposed to both the treatment and control conditions with the order of conditions counter-balanced (i.e., a cross-over design). Read Less

The goal of this observational study is to assess the potential non-invasive tools (e.g. regional ventilation, respiratory muscle response, lung mechanic's parameters) to identify the risk of failure when using high flow nasal cannula (HFNC) or non-invasive ventilation (NIV). The main question, it aims to answer is: Does abnormal regional ventilation could predict HFNC or NIV failure? Read Less
