This study pretends to evaluate the potential use of Hyfe Cough Tracker (Hyfe) to screen for, diagnose, and support the clinical management of patients with respiratory diseases, while enriching a dataset of disease-specific annotated coughs, for further refinement of similar systems.
Aspirin-Exacerbated Respiratory Disease (AERD), although uncommon in the general population, is an important phenotype of severe asthma and nasal polyposis where it occurs in 15% of severe asthmatics, and up to 30% of those with nasal polyposis. An important therapy for AERD is aspirin therapy after desensitization (ADAT). This is an inexpensive and proven therapy to improve the burden of sinus disease in AERD. Aspirin desensitization is the mechanism by which tolerance is induced in AERD patients. This is a 1-2 day outpatient procedure whereby increasing doses of aspirin are administered and the patients invariably experience some degree of hypersensitivity reactions. It is important to understand the effect of medications on the aspirin desensitization. It is known that the leukotriene modifier medications decrease the severity of the reactions in AERD. Other treatments such as antihistamines and the biologic agent omalizumab might have an effect on either blocking or blunting reactivity in AERD during desensitization. Dupilumab is a new respiratory biologic approved for atopic dermatitis, eosinophilic asthma and nasal polyposis. As such, it is well situated to be used for many AERD patients whose disease cannot be well controlled. The effect of dupilumab on the aspirin desensitization process and reaction is unknown and is the topic of this investigation. The primary objective is to determine the effect of dupilumab on reactions during aspirin challenge/desensitization.
The study presents an alternative method of tracheal dilatation in pediatric patients with acquired tracheal stenosis. Dilatation is performed by the use of balloon catheter connected with manometer, that is bronchoscopic guided into trachea in the stenotic area, through the wide canal of supraglottic device i-Gel. Every dilatation cession consists of three consequent tracheal balloon dilatations of maximum 3 minutes duration each, followed by 10-15minutes interval of controlled ventilation. The balloon is inflated for 60 seconds to reach predefined pressure, and then deflated. This method is minimal traumatic for tracheal mucosa, and application of several dilatation procedures every 2-3months, in pediatric patients with acquired tracheal stenosis, may lead to a relative reopening of trachea and recession of clinical symptoms.For the right performance of the dilatation procedure, patients receive general anesthesia with cessation of spontaneous ventilation. During procedure, controlled ventilation-oxygenation is impossible, because the i-Gel canal is occupied by bronchoscope and balloon catheter, so patients will remain apneic for a short period of time. For pediatric patients is important to perform proper preoxygenation prior to procedure, and to maintain oxygenation as long as possible during procedure. This is achieved by application of apneic oxygenation, through a small catheter, connected to high flow oxygen. Participants are exposed during first dilation to no oxygenation, while during second and third dilatation to apneic oxygenation. Aim of the study is to investigate primarily whether application of apneic oxygenation, in pediatric patients during tracheal balloon dilatation, maintains regional cerebral oxygen saturation rSO2 in significant higher levels, compared with no application of oxygenation. rSO2 levels are a sensitive index of oxygenation efficacy of the brain, accordingly this refers to a safe procedure. Secondary issues are whether application of apneic oxygenation maintains pulse oximetry SpO2 and artierial oxygen partial pressure PaO2 in higher levels, and what are the effects on arterial carbon dioxide partial pressure PaCO2 and on haemodynamic parameters (heart rate, blood pressure), compared with no application of apneic oxygenation.
Chronic respiratory diseases such as obstructive sleep apnea syndrome (OSA) and chronic obstructive pulmonary disease (COPD) constitute a major public health problem, due to their high prevalence, but especially because of their cardiovascular and metabolic morbidity and mortality and the associated costs for the health system. The organization of long-term management of these diseases is now part of the e-health process, digital health with the use of massive "big data" generated by care and follow-up. Therapeutic patient education and the integration of connected objects will allow personalized therapeutic education support with interventions by local medical staff adapted to the needs of the patients. This will also allow to objectify the effect of treatments such as continuous positive airway pressure (CPAP) for OSA or non-invasive ventilation (NIV) and/or oxygen therapy for COPD, not only on the prevention of respiratory decompensation but also on cardiovascular and metabolic risk factors which are major elements of the prognosis. This project will therefore make it possible to demonstrate the feasibility and to deploy a multi-actor care pathway in the territory. The investigators propose a prospective clinical study, conducted at the Verdun Hospital, with the main objective of studying the evolution of the quality of life of patients with a chronic respiratory pathology, during an integrated management at home for 6 months. The secondary objectives: - To study the evolution of the following parameters, before treatment (at inclusion) and after 6 months of integrated management: 1. Treatment compliance (CPAP or NIV/oxygen therapy) 2. Physical activity 3. Weight 4. Mean arterial pressure 5. Oxygen saturation, heart rate and respiratory rate for COPD patients 6. Severity of COPD for the patients concerned 7. Daytime sleepiness 8. Fatigue 9. Patient acceptability of the use of connected objects - To analyze the trajectories of the measures collected throughout the integrated management to identify specific profiles. - To analyze the daily data of the different connected objects and treatments with regard to the patients' profiles (according to age, gender, comorbidities, OSA or COPD group).
The purpose of the CircumVent Project is to evaluate the feasibility, adaptability and acceptability of a CPAP/O2 helmet solution for non-invasive ventilation among patients with COVID-19 and health workers in eight COVID-19 treatment and isolation centers in Nigeria.
Lung magnetic resonance imaging (MRI) with proton and inhaled inert gases has demonstrated a clinical ability to provide valuable structural and functional information in lung disease. Advances in lung MRI methods have led to the STH department handling clinical imaging referrals from local and national respiratory units. Hyperpolarised Xenon-129 gas MRI is now the gold-standard MRI modality used in clinical practice for asthma and COPD in Sheffield. In this new study, the investigators will use Xenon gas MR imaging and 19F gas MR imaging to obtain physiological, structural, and functional information about patients with known respiratory disease, namely asthma and COPD. Up to 20 patients with asthma and up to 20 patients with COPD will be recruited. Study visits will involve lung function tests and imaging using proton MRI, hyperpolarised xenon gas MRI, and 19F perfluoropropane MRI. After initial baseline assessments, patients will be followed up after 3 and 6 years to investigate the utility of MRI and lung function measurements in tracking disease progression over time. In addition, during the COVID-19 pandemic will also be studying the long term effects of this novel disease. The investigators will use Xenon gas MR imaging and pulmonary vascular 1H MR imaging to obtain physiological, structural, and functional information about patients with COVID-19, including hospitalised patients and mild, non-hospitalised COVID-19 patients. Participants may be invited for baseline assessments during the symptomatic phase of the disease and/or be followed up after 6, 12, 24 and 52 weeks (in line with clinical follow up for hospitalised patients) to investigate long term effects of this novel disease. This novel approach will provide mechanistic insight in to clinical observations such as : (i) why previously healthy patients can respond so poorly to oxygen/ventilation therapy, (ii) why patients respond to proning, and (iii) whether this is caused by alveolar-capillary interstitial changes and /or microvascular clotting in the pulmonary vasculature (leading to V/Q mismatch), and (iv) whether these acute changes lead to long term interstitial lung disease.
A cross-sectional study is expected to conducted by inquiring about the history, diagnosis results and medication details of respiratory diseases of the outpatient pediatric patients with respiratory diseases in the pediatric departments at specialist children's hospital at the second class and above, general hospitals and maternal and child healthcare hospitals. About 10,000 electronic questionnaires are expected to be collected in total, with about 100 participating hospitals and 100 electronic questionnaires from each participating hospital.Diagnosis and treatment information of pediatric patients are expected to be collected in the third week in April, July and October 2021 and in January 2022.
Chronic Respiratory Disease (CRD), particularly asthma and chronic obstructive pulmonary disorders (COPD) are leading causes of mortality and reduced quality of life due to its wide-reported association with other multi-morbidities.There is limited knowledge on the burden of CRD in the rural communities in Bangladesh due to poor awareness on the impact of CRD on quality of life and unavailability of diagnostic facilities due to weaker primary healthcare settings. The study aims to estimate the CRD burden in Bangladesh in a large representative population to draw the attention of policy makers to the creation of social awareness and improvement of primary healthcare infrastructure for respiratory disease in Bangladesh. The study is a prospective observational one in nature. The study will be implemented in Mirzapur, a rural sub-district of Tangail district in Bangladesh within the period of February to May 2021. A total of 981 participants will be enrolled from the study. Verbal consent will be taken initially. Participants who are assessed to be COVID-19 negative will be invited for a visit to the mobile clinic following national health guidelines to perform the spirometry. The study team will provide an information sheet (written in local language) that describes the study aim and objectives with potential risk benefits to the participants. All participants will be enrolled through written consent and satisfactory response to the patient information sheet. The Research Assistant (RA) will collect the relevant metadata such as demographics, information on risk factors, screening questionnaires relevant to asthma and COPD, reported health status and symptoms related to CRD etc. from the participant after obtaining the written consent. Data quality will be ensured by the Field Research Supervisor through checking all the collected information. The enrolled participants will undergo spirometry for the evaluation of their lung function. Spirometry will be collected by trained personnel and will be quality checked by an expert panel at CHRF. Repeated collection will take place in the event if the test results do not pass quality checking. Participant will also be invited to the study clinic within the next 10 days after assessment for any further clinical assessment that is deemed necessary by the study physician. The collected data and spirometry reports will be reviewed to evaluate the CRD patient in terms of their disease. The study will analyse the rate of CRD burden stratified by age, sex, and income group. The productivity loss will be measured in terms of work hours lost due to CRDs.
