Filter by:The overall aim of the study is to determine the clinical efficacy and mechanisms of action of anti-IL-4a (dupilumab) as treatment for patients with Aspirin-Exacerbated Respiratory Disease (AERD).
The purpose of this study is to evaluate the feasibility and the mid-term effects of a pulmonary rehabilitation intervention, delivered by digital App, on quality of life of patients affected by respiratory diseases. The App will include a monitored exercise training program based on most recent cardiopulmonary rehabilitation guidelines, including alerts, reminders and educational contents as well as chat and online visits with healthcare professionals to improve patient engagement.
There are many techniques that can allow for the quantification of lung function in children; some are being used clinically and others are under development. Many of these tools are available at BC Children's Hospital. This registry study will act as a central repository for the results of traditional and novel pulmonary function tests done at BC Children's Hospital to allow for future analysis.
The investigators expect to reveal the association between air pollution and childhood respiratory diseases through a multi-center observational study, and summarize the relationship between air pollution and childhood respiratory diseases.
Symptoms such as cough, wheeze, and breathlessness are among the most common reasons for general practitioner or emergency department visits in the UK. Such symptoms have a profound impact on patients' ability to live a fulfilled life, often rendering people unable to work and socialise. Azithromycin (a type of antibiotic) improves symptoms and reduces flare-ups of diseases such as asthma and chronic obstructive pulmonary disease (COPD). The reason why it works is unclear. Many people believe that it either decreases the number of bacteria in the lungs or reduces inflammation in the lungs and the upper airways. Neither theory is proven. Another possible mechanism that has been much less studied is that Azithromycin encourages the body to move food and fluid through the gut more quickly, thus preventing reflux and aspiration of small food particles and stomach acid. It has been shown that lung damage can occur when gut contents enter the airways, which may contribute chronic lung disease patients' symptoms In this study the investigators will test the effect of azithromycin on the gut in patients with chronic lung diseases. The investigators will measure the strength of a patients swallow by measuring the pressures in their gullet, using high-resolution oesophageal manometry (HROM), before and after treatment, in people being started on azithromycin as part of their routine care. The investigators will also measure the effect that azithromycin has on their symptoms and observe whether there is a relationship between the strength of their swallow and their symptoms. At the end of this study, the investigators hope to better understand the way in which azithromycin helps to improve the symptoms of patients with chronic lung diseases. The investigators also hope to open the door to investigate the effect of other drugs that improve gut function in patients with chronic lung diseases.
The study is conducted in the context of the COVID-19 pandemic in general, and more specifically in the context of the evaluation of the use of protective masks as a barrier to the spread of the virus. The wearing of masks is one of the recommended barrier measures to limit the spread of the SARS-CoV-2 virus responsible for COVID-19. It is recommended in all circumstances, and mandatory in some. Regardless of the type of mask used (noting that the so-called "surgical" masks are by far the most common), there are various disadvantages associated with wearing them. Dyspnoea (unpleasant or upsetting perception of respiratory activity) is one of these disadvantages. It can lead to reluctance to wear the mask, or to the adoption of inappropriate practices that reduce its effectiveness. This "side effect" of the mask is more pronounced in patients with underlying respiratory diseases. However, not all mask designs are equivalent in terms of their physical properties, which can theoretically generate varying levels of dyspnoea. It is therefore important to determine which mask designs are more or less dyspnogenic, in order to guide the preferential use of certain designs in certain patient categories. The TOLMASK study (Tolerance of SARS-CoV2 Surgical Masks in Patients with Chronic Respiratory Diseases) is a prospective, randomised, triple-blind, single-centre study comparing several surgical masks in a crossover design. The primary objective of the study is to evaluate the respiratory tolerance of different surgical masks and the secondary objective is to evaluate their general tolerance.
Obesity Hypoventilation Syndrome is defined as a combination of obesity (BMI ≥ 30 kg/m2) and daytime hypercapnia in arterial blood gas analysis (PaCO2 > 45 mmHg) without other pathologies that cause hypoventilation. Symptoms seen in individuals diagnosed with OHS are stated as a feeling of suffocation due to apnea, loud snoring, morning headache and excessive daytime sleepiness. Respiratory mechanics, respiratory muscle performance, pulmonary gas exchange, lung functions and exercise capacity parameters are adversely affected in patients. Early treatment is important so that these negative changes do not lead to worse outcomes. Weight control, bariatric surgery, pharmacological treatment and non-invasive mechanical ventilation (NIMV) are included in the treatment program of OHS patients. The effects of exercise on the treatment program of OHS patients are unknown. Considering all the studies in the literature, the primary purpose of this study is to evaluate aerobic and strength training on exercise capacity and sleep quality in patients with hypoventilation syndrome. The secondary aim is to examine the effect of this exercise training on peripheral muscle strength, emotional state, body composition and quality of life parameters. In addition, the researchers believe that this study will form the basis for further scientific studies on OHS and exercise and will make an important contribution to the literature.
The purpose of the study is to prove the clinical superiority of respiratory rehabilitation software "Redpill Breath" and evaluate the clinical improvement effect by 6-minute walk test of the software, compared to the manual rehabilitation management for those who need respiratory rehabilitation(COPD, Asthma, Lung Cancer, etc.)
Objectives and aim: To evaluate the long-term spill-over (indirect) effect of Coronavirus disease (COVID-19) on health outcomes and healthcare utilization among people with non-communicable diseases and without COVID-19. Design: A population-based cohort study using electronic health records of the Hospital Authority (HA) clinical management system, economic modeling, and serial cross-sectional surveys on healthcare service utilization. Setting: HA public hospitals and outpatient clinics in Hong Kong Participants: People aged ≥ 18 years with a documented diagnosis of diabetes mellitus, hypertension, cardiovascular disease, cancer, chronic respiratory disease, and chronic kidney disease; without COVID-19; attending HA services between 2010 and 2024. Main outcome measures: All-cause mortality, disease-specific outcomes, healthcare service utilization, and costs. Methods: The annual incidence of each outcome in each year between 2010 and 2024 will be calculated. An interrupted time-series analysis to assess the changes in outcomes between pre-and-post-COVID-19 outbreak periods. Long term health economic impact of healthcare disruptions during the COVID-19 outbreak will be modeled using microsimulation. Multivariable Cox proportional hazards regression and Poisson/negative binomial regression to evaluate the effect of different modes of care on the risk of the outcomes. Implications: Findings will inform policies and practices on contingency care plans to avoid excessive morbidity and mortality and to assure the quality of care for patients with NCD as part of the territorial response to the health crisis.
Background: Many adults and some children with COVID-19 or acute respiratory infection become critically ill and need advanced life support in the Intensive Care Unit (ICU). Frailty is a medical condition of reduced function and health. Adults with frailty have a lower chance of surviving critical illness. The investigators are still learning about critically ill adults with COVID-19 or acute respiratory infection, and do not have much information on how frailty affects outcomes in critically ill children, with or without COVID-19 or acute respiratory infection. Rehabilitation can help survivors of COVID-19 or acute respiratory infection by improving strength and improve quality of life (QOL). Objectives: The main goal of this research study is to see if patients with frailty have a lower chance of surviving COVID-19 or acute respiratory infection critical illness and more health problems after survival than patients without frailty. The investigators will also study the types of rehabilitation received by patients with COVID-19 or acute respiratory infection. Methods: The investigators will include adults and children with COVID-19 or acute respiratory infection who are admitted to the ICUs that participate in the study. The investigators will gather data about each patient, including before and during their illness. Outcomes: The investigators will collect level of frailty, function, and types of therapy, or rehabilitation received by patients. In adults, the investigators are most interested in learning if frailty influences mortality, or death. In children, the investigators are most interested in whether children with COVID-19 or acute respiratory infection critical illness are more likely to develop frailty. The investigators will also study post-hospital discharge location in survivors (e.g., home, rehabilitation). Relevance: The COVID-19 pandemic is a global public health crisis. It is critical to understand how COVID-19 and other acute respiratory infection critical illness affects groups of people who are at higher risk, and the impact on outcomes that are important to patients, like functioning and QOL. The results will help policy makers plan post-hospital services for survivors, help healthcare workers understand the importance of rehabilitation practice for patients with COVID-19 or acute respiratory infection, and help researchers develop treatments to improve QOL after COVID-19 or acute respiratory infection.
