NCT04225897
The purpose of this clinical trial is to learn about the safety and effects of the study medicine (sisunatovir). Sisunatovir is developed as potential treatment of Respiratory Syncytial Virus (RSV) infections. This study will assess sisunatovir as compared to placebo in infants aged 1 month to 36 months who are hospitalized with RSV lower respiratory tract infection (LRTI). A placebo looks like the study medicine but does not contain any active medicine in it. This study will be conducted in 3 parts: In Part A participants aged 6 months to 3 years will be given a single dose of 2.5 mg/kg of sisunatovir in Cohort 1. In Cohort 2, participants age 1 month to 6 months will receive a single dose of 2 mg/kg of sisunatovir only after the completion of Cohort 1. 12-24 participants will be enrolled in Part A In Part B participants age 1 month to 36 months will receive sisunatovir or placebo dosed every 12 hours for 5 days. Doses for part B will be determined after the completion of Part A. 24-40 participants will be enrolled in Part B. The dose regimen for Part C will be determined after the completion of Part B. Approximately 120 participants age 1 month to 36 months will receive either sisunatovir or placebo. To participate in this study participants must meet the following criteria: 1. Age 1 month to 36 months 2. Weight ≥ 3.5 kg 3. Diagnosis of LRTI 4. Diagnosis of RSV 5. Hospitalization due to RSV LRTI
NCT02809235
In this proof of concept study, the investigators aim to determine if supplementation with coconut oil causes an increase in cholecystokinin and cholecystokinin receptor expression in the airway smooth muscle of lean asthmatics, and whether these changes correlate with changes in airway stiffness (estimated by bronchodilator reversibility, airway reactivity, and airway resistance) or symptom control. The investigators propose a 5 week, single center trial in 20 lean patients with mild asthma (not taking inhaled corticosteroids) aged 18 and older. Subjects will supplement their usual diets with 3 tablespoons of coconut oil, a commercially available oil with high dodecanoic acid content, for 3 weeks. To quantify changes in airway smooth muscle cholecystokinin and cholecystokinin-receptor expression, each subject will undergo bronchoscopy with endobronchial biopsies before and after coconut oil ingestion. For the secondary analysis, subjects will also complete spirometry with bronchodilator testing, methacholine challenge, body plethysmography, and an Asthma Control Questionnaire (ACQ) before and after the dietary intervention. This information will be used to compare the changes in airway smooth muscle cholecystokinin and cholecystokinin receptor expression to changes in bronchodilator reversibility, airway reactivity, airway resistance, and symptom control. In the exploratory aims, the investigators will correlate the changes in airway smooth muscle cholecystokinin and cholecystokinin receptor expression with changes in FEV1 and peak flow measurements. The investigators therefore hope to elucidate information about the mechanistic role of cholecystokinin in airway smooth muscle stiffness and contraction.
NCT03583814
The study's purpose is to evaluate the RI-Asthma Integrated Response (RI-AIR) Asthma Care Implementation Program (ACIP). RI-AIR ACIP uses an electronic information system to screen children with asthma and identify what specific services each child needs based on the child's asthma symptom and health care status. Our main goal is to see if children experience better asthma outcomes as a result of participation in the program. We will provide our intervention to 434 urban, ethnically diverse children, between 2-12 years old with asthma, and their families and evaluate whether participating in the program improves children's asthma outcomes. The second goal is to evaluate how well the program is set up and how we can make improvements to better serve families of children with asthma. The third goal is to gather information and advice from community experts so that we can make the program sustainable. Families that take part in RI-AIR ACIP will participate in the program over the course of a year, including participating in the intervention, and brief follow up visits at 3, 6, 9 and 12 months after completing the intervention. All families will complete the CASE program, which takes place over the course of about 4 weeks and involves in-school or remote school-based asthma education for school aged children, after-school or remote education sessions for their parents, asthma care training for school staff, and an evaluation of asthma triggers in the school. Families of children who have more frequent asthma symptoms and emergency healthcare visits will also compete the HARP program, a home-based program consisting of 3 home sessions (over about 6 weeks) that include individualized asthma education and strategies and supplies for controlling environmental asthma triggers. Both CASE and HARP programs are carried out by certified asthma educators and community health workers. Each child's healthcare provider (HCP) and school nurse teacher (SNT) will receive a standardized, secure email indicating the child is participating in RI-AIR. This email will include a summary of the child's baseline assessment of asthma control and prior health care use, and a description of the program. At the conclusion of the child's participation, the HCP and SNT will receive a summary by secure email summarizing the child's asthma control at the end of the intervention, services delivered, and referrals made, and for HARP participants, triggers observed in the home and supplies and referrals provided.

This study will analyze gene expression and other laboratory data from biological samples collected from participants with suspected respiratory, urinary, intra-abdominal, and/or skin \& soft tissue infections; or suspected sepsis of any cause.
NCT06067191
The purpose of the study is to learn about the safety, pharmacokinetics and antiviral activity of the study medicine (RV299) for the potential treatment of respiratory syncytial virus (RSV). RSV is a highly contagious virus that can lead to serious lung infections in patients with reduced ability to fight infection. Most vulnerable populations include babies, the elderly and patients that have received a bone marrow transplant.
NCT06650917
Objective: To explore the application effect of acupoint massage combined with ear point pressing beans in the remission stage of asthma. Methods: 120 children with asthma in remission who were treated in pediatric outpatient department from January 2016 to October 2022 were randomly divided into experimental group and control group, with 60 cases in each group.The patients in both groups were treated with salmeterol and fluticasone inhalation powder once a day, twice a day. The patients in the control group were treated with acupoint massage on this basis. Acupoint massage once a day from Monday to Friday, lasting for 30 minutes each time.The patients in the experimental group were treated with ear point pressing beans on the basis of the control group. The ear point pressing beans is performed once a day from Monday to Friday. Changes in pulmonary function and asthma control were observed before and after treatment in the two groups were observed, and forced expiratory volume 1 second (FEV1),forced expiratory vital capacity (FVC), FEV1/FVC, asthma control test scale (ACT) score were compared.
NCT06011356
Aims of the study: 1. To deliver a scalable wellbeing programme to the local population of Imperial College Healthcare NHS Trust, focusing on movement. 2. To describe the natural history of long-term conditions using digital data from a smartwatch. 3. To identify digital information that is routinely collected by a smart watch that can be used to predict outcomes in patients with long term conditions. 4. To identify factors that determine whether participants engage with and improve in a movement programme. Adult patients who are registered to the Imperial NHS Care Information Exchange (CIE), an NHS patient-facing electronic health record, are eligible to participate in the study. Participants will receive a smart watch for self-monitoring of their movement and wellbeing and be asked to wear the device as much as possible. They will be asked to download a smartphone application called Connected Life, which displays movement and information on heart rate, breathing and oxygen levels to both the participant and the research team (digital data). Participants will receive secure login details for the Connected Life application from the research team, to ensure data privacy. The research team will look at participants' health records, and attempt to identify associations between the digital data and clinical information. This will allow the research team to identify digital data that predicts the onset and natural history of long term conditions, which may potentially allow for earlier diagnosis for future patients. The primary outcome of the study is the identification of trends in movement based on step-count data recorded by the smartwatch.
NCT06630078
Acute and Chronic respiratory conditions represent a leading cause of death and morbidity in children and adults worldwide. The diagnosis of bronchiolitis and asthmatic exacerbations is based on clinical, and mostly subjective, clinical parameters with moderately accurate prognostic role. Patients undergoing neck radiotherapy need invasive assessments of larynx. A simple biomarker like Voice may facilitate the management of these conditions. Recent studies showed that VOICE may be used as a good and easy biomarker to diagnose and monitor several respiratory and non-respiratory conditions. A prospective study aimed to collected VOICE and other clinical data in adults and children with common acute and chronic respiratory conditions at high impact on healthcare systems will be performed. VOICE-omic data will be linked with clinical findings generating data integration, using artificial intelligence technology to develop a Decision Support Systems to provide the basis for non-invasive personalised early recognition, diagnosis, monitoring and prognosis of patients with these conditions.
NCT06096376
Ultrasound of the diaphragm is an easily reproducible bedside tool that provides a non-invasive measurement of inspiratory muscle function and respiratory efficiency. The diaphragmatic thickness correlates with the strength and muscle shortening and is reflective of its contribution to the respiratory workload. Diaphragm thickening fraction (DTF) has been shown to be predictive of extubation failure in ventilated patients. However, whether measurements of DTF are predictive of high flow nasal cannula (HFNC) outcomes in patients with acute hypoxemic respiratory failure (AHRF) remains unknown. The objective of this study is to identify predictors of HFNC failure by diaphragm ultrasound and to compare its performance with the well-established ROX index.
NCT04896502
The study is about comparing asthma home assessments/interventions by telemedicine compared to providing education alone. Interactive Video (IAV) defines telemedicine. It allows two-way communication in real-time with both audio and visual communication between the subject and someone from the study team. It is similar to using Face Time on a mobile device. Asthma home assessments/interventions are used to identify things in a home that can make asthma symptoms worse, called triggers. Reducing these triggers in the home can improve asthma.
NCT06096363
Right ventricular dysfunction (RVD) and right ventricular-pulmonary arterial (RV-PA) uncoupling detected by transthoracic echocardiography (TTE) in acute respiratory distress syndrome (ARDS) are associated with poor survival. Early detection of RVD and RV-PA uncoupling in patients with acute hypoxemic respiratory failure (AHRF) may be indicative of worsening and decompensating pulmonary condition which may require escalation of respiratory support. The use of TTE parameters in predicting high-flow nasal cannula (HFNC) failure has not been previously studied. The objective of this study is to identify predictors of HFNC failure by TTE and to compare its performance with the well-established ROX index.
NCT06016244
The goal of this clinical trial is to find out at which lower limit for saturation (amount of oxygen in the blood) we can best give extra oxygen to children that have been admitted for shortness of breath. We hope to accomplish a shorter period of illness for these children and that they can be discharged home earlier. Participants will receive supplemental oxygen if their blood oxygen levels are below 88% or below 92%. After admission, (parents of) participating children will fill out questionnaires. We will compare the two groups on their hospitalization duration and recovery. In other words, is it better to maintain a lower limit of 88% saturation or a lower limit of 92% in children admitted for shortness of breath?
NCT06642285
This study aims to evaluate the effect of implementing evidence based practices on prevention of associated nasal pressure injuries among preterm neonates with non invasive respiratory support
NCT06371378
The aim of this study was to predict the effect of gastric antrum diameter before extubation on intra-abdominal pressure changes and consequently on the risk of pulmonary aspiration in patients undergoing elective spinal surgery under general anaesthesia in the prone position in the Neurosurgery Operating Theatre of the Ministry of Health Ankara City Hospital and to take precautions accordingly. Gastric antrum diameter and intraabdominal pressure measurements may contribute to the improvement of anaesthetic practice by reducing the risk of pulmonary aspiration and additional complications.
NCT06637748
Bronchial asthma is a common respiratory disorder among children, worldwide. Asthma is characterized by chronic inflammation and remodeling of the airways induced by recurrent exposure to hypoxemia that leads to repeated tissue injury and repair. The interaction between respiratory diseases and cardiovascular function is complex . Cardiac dysfunction can be attributed to pulmonary hypertension (PH) secondary to recurrent hypoxia in patients with bronchial asthma. PH affects the pulmonary vasculature by releasing various cytokines leading to pulmonary vasoconstriction and enhancing the remodeling process with muscularization and proliferation of the vascular media and intima . Other hypotheses concluded that the exaggerated respiratory efforts may raise the intrathoracic pressure and increase right ventricle (RV) afterload and consequently RV hypertrophy and/or dilatation . Children with severe bronchial asthma can experience cor pulmonale later in life, but little is known about the early cardiac changes that might be present during childhood especially for mild or moderate persistent asthma. Some studies have reported right ventricular dysfunction as the earliest hemodynamic change among those cases . Other studies did not report these results and reported impaired systolic function of the left ventricle (LV) even before diastolic dysfunction . Insufficient control of BA, in turn, can cause the formation of various pathological conditions. For example, there are studies showing the risk of cardiac arrhythmias and conduction disorders in patients with uncontrolled BA due to functional changes or pathological remodeling of the myocardium . Atrial remodeling, which is the pathomorphological basis of serious supraventricular cardiac arrhythmias, has a more rapid progression with poor BA control and is formed as a result of excessive stretching of the atrial wall, as well as other adverse factors . The connection between BA and supraventricular arrhythmias, including atrial fibrillation (AF), was noted in studies by Cepelis et al. Available data indicate that in the adult population, cardiac arrhythmias are significantly more common in patients with BA than in those without it (9). The results of a Norwegian population study HUNT study, demonstrate that the risks of supraventricular arrhythmias and AF are increased in patients with an uncontrolled BA . Electrocardiography (ECG) is the universal screening method for assessing the state of the atrial myocardium and the conducting system of the heart. According to German et al. ECG analysis can make a significant input to the assessment of the risk of formation of supraventricular rhythm and conduction disorders. Therefore, the analysis of the atrial component of the ECG, and atrioventricular conduction in patients with BA is an important component of the management of these patients, especially in pediatric practice. Consequently, the study of the characteristics of the ECG and its supraventricular component in children with BA is relevan

Cerebral desaturations occur frequently in patients undergoing non-cardiac surgery. The definition of what constitutes a cerebral desaturation, the incidence of the phenomenon, the association between desaturations and perioperative outcome, and the mechanistic explanations of cerebral desaturations remain unexamined. This study seeks to identify the true incidence and magnitude of cerebral desaturations in high-risk non-cardiac surgical patients and the association between desaturations and perioperative outcome. The investigators will attempt to determine the following (1) The proper definition, incidence and severity of decreased cerebral saturation (rSO2) in high-risk non-cardiac surgical patients (2) the mechanisms surrounding decreases in rSO2 by correlating it with alterations in physiologic parameters (such as blood pressure, cardiac output, hemoglobin concentration, and carbon dioxide levels) and (3) to correlate the incidence and severity of decreased rSO2 with relevant perioperative. The investigators will also analyze a panel of inflammatory biomarkers to determine if these biomarkers have the ability to predict postoperative complications. The investigators will study 200 high-risk patients undergoing high-risk non-cardiac surgery. The investigators will determine the incidence and severity of decreases in rSO2, the associated factors with the occurrence of decreased rSO2, and the relationship between decreases in rSO2 and adverse perioperative outcome with a composite of well defined perioperative complications such as death, myocardial infarction, cerebrovascular accident, acute kidney injury, delirium, postoperative infections, and the need for mechanical ventilation.
NCT06640777
Acute Respiratory Distress Syndrome (ARDS) is a serious condition where people in hospital care suddenly have trouble breathing because of infection, pneumonia, COVID-19 or other disease. People with ARDS may have to be put in an intensive care unit (ICU) and on a ventilator to help them breathe. This trial is to try to find out if injecting a product called LEAF-4L6715 makes the treatment better or worse than what is normally given. LEAF-4L6715 is a product that contains tiny bubbles to slowly release a substance named transcrocetin which scientific studies show may increase oxygen flow and reduce inflamed cells and protect tissues of the body.
