Aim is to to demonstrate that the ResAppDx v2.0 algorithms provide an accurate diagnosis of respiratory disease in the study's clinical setting compared to a clinical adjudication committee's (CAC) diagnosis; and to establish a baseline for the resource use and cost of current care pathways for respiratory disease diagnosis in an emergency department. Eligible subjects will be consented/enrolled and their subject reported signs/symptoms of respiratory disease will be recorded in the study electronic case report form (eCRF). The enrolled subject's cough sounds will be captured (5 cough sounds are required) using the ResAppDx v2.0 Investigational Device (ID) software installed on a study smartphone; cough sounds may be voluntary and/or involuntary/spontaneous. As this is an observational study the treating team will be blinded to the ResAppDx v2.0 diagnoses. Additional medical information will be collected from the treating team, from the subject and from the subject's medical record. No follow-up/subsequent visits with the subject will be required by the study. As an efficacy comparator, a clinical adjudication committee (CAC) will determine the final clinical diagnosis using the disease case definitions, eCRF data and the subject's medical record. Information on time and scope of tests and consults ordered by the treating team will be recorded to set a baseline for resource use and cost of current standard of care treatment/assessment procedures. This data will allow future health economics analyses to be performed. The blinded ResAppDx v2.0 diagnoses will be unblinded after database lock and sensitivity and specificity will be calculated for the ResAppDx v2.0 diagnoses compared to agreement with the CAC's final clinical diagnoses.
Aim of study is to demonstrate that the ResAppDx v2.0 algorithms provide an accurate diagnosis of paediatric respiratory disease in the study's clinical setting compared to a Clinical Adjudication Committee's (CAC) diagnosis; and to establish a baseline for the resource use and cost of current care pathways for paediatric respiratory disease diagnosis in an emergency department. Eligible subjects/parents will be assented/consented, enrolled and their subject reported signs/symptoms of respiratory disease will be recorded in the study electronic case report form (eCRF).The enrolled subject's cough sounds will be captured (5 cough sounds are required) using the ResAppDx v2.0 Investigational Device (ID) software installed on a study smartphone; cough sounds may be voluntary and/or involuntary/spontaneous.

Patients with chronic respiratory disease may be prescribed oxygen therapy. Currently, the dose of oxygen flow is fixed (FixedO2) depending on activity level i.e. rest, physical activity and sleep. Automated Titration of Oxygen (AutoO2) is a closed-loop system in which the oxygen flow to the patient is continuously machine adjusted to meet the patient's immediate needs on the basis of signals from pulse oximetry (SpO2). The purpose of this study is to examine if automated oxygen control based on pulse oximetry provided to participants is superior to prescribed fixed oxygen flow in keeping SpO2 within the intended target interval of 92 to 96% arterial oxygen saturation.
Vapendavir (VPV) is a drug being developed to treat human rhinovirus (RV) infection, one virus responsible for the common cold. Vapendavir prevents the virus from entering cells and making more infectious copies of itself. A study is being planned to investigate VPV in patients with chronic obstructive pulmonary disease (COPD, a lung disease making it difficult to breathe) who develop a rhinoviral infection; however, VPV has not been approved for use in treating any indication (disease) by the FDA or any other global regulatory agency. Therefore, VPV is considered investigational, and the study doctor is conducting this investigational research study. Safety will be monitored throughout the entire study.
Acute respiratory infections are common diseases worldwide with the highest incidence and mortality rates, especially among children. Currently, the prevention of acute respiratory infections in children still faces certain limitations. Although there is a vaccine available for influenza, there are no vaccines yet for RSV and adenovirus in children, and influenza vaccination needs to be repeated annually to achieve optimal effectiveness. Therefore, maintaining respiratory and throat hygiene is essential for both treatment and prevention, ensuring respiratory health for children and reducing the risk of bacterial co-infections. In recent years, preventive strategies for respiratory inflammation have garnered increasing attention, with probiotics being shown to have the potential to support treatment and prevention & reduce the risk of recurrent respiratory infections, thus decreasing reliance on antibiotics. Here, the investigators propose that direct nasal spraying of probiotics may be safe and effective in preventing respiratory diseases. The aim of the study is to evaluate the effectiveness of two types of nasal- praying Bacillus probiotics including LiveSpo Navax (1 billion/mL x 30 mL B. subtilis and B. clausii) and LiveSpo Navax Kid (0.6 billion/mL x 30 mL B. subtilis and B. clausii) in preventing respiratory diseases. Study Population: The sample size is 600. Description of Sites: The study is conducted at preschools in Son Tay Province, Hanoi, Vietnam. Description of Study Intervention: A total of 600 eligible children are randomly divided into three groups (n = 200/group each). Children in the Control group received 0.9% NaCl physiological saline twice daily (morning and afternoon), with 2 sprays in each nostril and 2 sprays in the throat each time (totally 6 sprays each time), continuously for four weeks. Children in the Probiotic 1 group receive LiveSpo Navax product, and children in the Probiotic 2 group receive LiveSpo Navax Kid, with the same dosage and frequency as the Control group. Study Duration: 12 months.
The aim of this study is to validate the six minute Stepper Test (6MST) and the 5-repetition chair lift test (5STS) as measures of exercise tolerance and muscle power, respectively, in patients with chronic respiratory disease. As the reproducibility of the tests has been studied and validated in previous studies, the objective is to investigate the validity of the 6MST and 5STS in comparison with their respective gold standards.
The aim of this study is to investigate the nutritional status of patients with chronic pulmonary disease undergoing regular outpatient pulmonary rehabilitation.
This research was planned as a randomized controlled experimental type to determine the effect of using a projector caleidoscope and matching card on children's fear and physiological parameters in 3-6-year-old children who were administered inhaler medication. According to the power analysis performed for the sample size, the power of the sample was calculated with the G*Power 3.1 program in line with the literature. While the amount of Type I error was 0.05 and the power of the test was 0.95 (α= 0.05, 1-β= 0.95), the minimal sample size was calculated as 105 children (35 children in each group). Considering the possible losses from the sample for any reason during the study period, it was planned to increase the number of samples by 10% and include 38 children in the study and control groups. The data of the research will be collected using the following data collection tools; Child Information Form and Fear Rating Scale
This study will investigate the role of a portable Continues Positive Airway Pressure device (pCPAP) in management of patients with symptomatic Excessive Central Airway Collapse (ECAC). ECAC is characterised by complete or partial collapse of central airways on exhalation. In some cases, this can cause persistent breathlessness and severely limited exercise capacity. Current treatment options for ECAC are very limited. Standard assistive breathing devices such as CPAP machines are sometimes used to relieve symptoms at night or at rest. This does not address breathlessness during activity which drives accumulation of disability over time. The main aims of this project are to assess the effect of a portable CPAP (pCPAP) device on exercise capacity and symptoms and evaluate the feasibility of wearing pCPAP at home during routine activities. Lightweight battery-powered portable CPAP devices have been recently developed to facilitate travel to remote areas by people with Obstructive Sleep Apnoea (OSA). Patients with ECAC can wear them during physical activity to prevent airway collapse but their potential benefits have not been evaluated in clinical trials. For this study, the investigators will recruit 20 patients with ECAC who will attend for two study visits 4-6 weeks apart in a single centre (The Royal Papworth Hospital). The primary outcome measure will be a shuttle walk test performed repeatedly with and without pCPAP in a randomised order. Secondary outcomes will include assessment of activity level, breathlessness, quality of life ,pCPAP usage and its acceptability. The study will evaluate a pragmatic way of CPAP titration and application. Previously acquired diagnostic baseline computed tomography (CT) scans will be analysed with a novel Functional Respiratory Imaging (FRI) tool. This software tool will enable retrospective reflections on the changes occurring within the lungs for patients with ECAC. This may help identify predictive features of potential pCPAP responders and inform future use.
