Filter by: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.
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.
There is evidence from randomized controlled trials in adult patients with Acute Respiratory Distress Syndrome (ARDS) suggesting that delivering small tidal volumes with adequate levels of Positive End-Expiratory Pressure (PEEP) and a restrictive fluid strategy could improve outcome. However, there are data and common bedside experience that individual patients may or may not respond to interventions, such as escalation of PEEP or positional changes, and there may be a role for a more personalized ventilator strategy. This strategy could account for the unique individual morphology of lung disease, such as the amount of atelectasis and overdistension as a percentage of total lung tissue, the exact location of atelectasis, and whether positional changes or elevation of PEEP produce lung recruitment or overdistension. Stepwise Recruitment maneuvers (SRMs) in pARDS improve oxygenation in majority of patients. SRMs should be considered for use on an individualized basis in patients with pARDS should be considered if SpO2 decreases by ≥ 5% within 5 minutes of disconnection during suction or coughing or agitation. If a recruitment maneuver is conducted, a decremental PEEP trial must be done to determine the minimum PEEP that sustains the benefits of the recruitment maneuver. Electrical impedance tomography (EIT), a bedside monitor to describe regional lung volume changes, displays a real-time cross-sectional image of the lung. EIT is a non-invasive, non-operator dependent, bedside, radiations-free diagnostic tool, feasible in paediatric patients and repeatable. It allows to study ventilation distribution dividing lungs in four Region Of Interest (ROI), that are layers distributed in an anteroposterior direction, and shows how ventilation is distributed in the areas concerned. EIT measures and calculates other parameters that are related not only to the distribution of ventilation, but also to the homogeneity of ventilation and the response to certain therapeutic maneuvers, such as SRMs or PEEP-application. Aim of this study is to provide a protocolized strategy to assess optimal recruitment and PEEP setting, tailored on the patients individual response in pARDS.
A major obstacle in precision medicine is the unavailability of biomarkers that are easy to access, non-invasive, measurable with high-performance techniques, fast, easy to use, reproducible, inexpensive and easily deployable on a large scale. The analysis of exhaled air (volatolomics) is an "omics" approach devoted to the analysis of volatile organic compounds (VOCs) eliminated by the pulmonary route with real-time detection, at the patient's bedside. The reference technology for the analysis of VOCs is mass spectrometry (MS). Several types of mass spectrometers can be used, and, in the absence of a consensual and standardized method, have practical methods for carrying out different analyzes which also lead to the generation of specific signals whose nature, complexity and exhaustiveness of information generated are heterogeneous. The clinical studies carried out to date use one of the analytical techniques available, without the choice necessarily being guided by objective factors. The objective of this study is to fill this gap and compare the information obtained by three mass spectrometry techniques available to our team (proton transfer reaction - mass spectrometry (PTR-MS), Soft Ionization by Chemical Reaction in Transfer (SICRIT) , two-dimensional gas chromatography-mass spectrometry (GCxGC-MS)) for volatolome analysis. The comparative analysis of the different signals will make it possible to determine the interests and limits of each technique and thus to direct preferentially towards one, the other, or combinations of them for the realization of future clinical studies. One of the main challenges also consists in establishing the concordance of the signals generated by the different technological approaches, some employing prior chromatographic separation, others not, and some employing soft ionization methods while those of others are on the contrary hard. Thus, the availability of datasets obtained on the same population with these complementary approaches will allow significant progress for the identification of the COVs of interest in clinical studies, beyond the simple comparison of the analytical performances of the different methods.
The goal of this randomized controlled trial is to evaluate the impacts of an attachment-based intervention (Attachment Biobehavioral Catch-Up (ABC) and Home Book-of-the-Week (HBOW) program on emerging health outcomes (i.e., common childhood illnesses, body mass index, and sleep) in low-income Latino children (N=260; 9 months at enrollment). It is hypothesized that children randomized to ABC will have better health outcomes in comparison to the HBOW control group.
Premature infants are susceptible to complications related to infrequent and non-standardized oral care. Although the benefits of frequent standardized oral care are known to reduce oral dysbiosis (increased level of potentially pathogenic bacteria) and its associated complications in critically ill adults leading to established evidence-based guidelines, no such information exists for VLBW infants. The proposed study will prospectively follow 168 VLBW infants for 4 weeks following birth.
A prospective basic science study for collection of training and testing data for development of Lifelight® Junior
Patients referred to internal medicine wards are becoming increasingly complex and fragile. Despite deep knowledge of their specific disorders, steps are required to improve overall management of their acute and chronic conditions. The main objective of the study is to identify demographic, clinical, laboratory and radiological markers of disease severity and activity in patients with diseases treated at general medicine wards (respiratory disease, immune-mediated disease, sepsis, metabolic disease, rare disease, frailty, pregnancy pathology) in order to improve their diagnosis, monitoring and treatment processes.
Human rhinovirus is also called the "common cold virus" because it causes at least half of all of the common colds experienced each year. In patients with asthma, getting a rhinovirus infection can cause worsening of asthma symptoms. Although these symptoms are well known, researchers do not fully understand how the virus worsens these asthma symptoms, nor do they really know whether virus infection causes longer term structural changes (often referred to as airway remodeling) in the airways. This study plans to address and answer these questions. Doing so will provide the researchers with a better understanding of how to treat the worsening of asthma that are caused by human rhinovirus infections. The epithelial cell is the cell that lines the surface of your airways from your nose down to your lungs, and is also the cell type that gets infected by rhinovirus. At present, it is thought that the virus causes symptoms by changing epithelial cell biology in a way that causes airway inflammation. Some of these inflammatory molecules are also thought to cause scarring (remodeling) of the airways, which over time, may lead to a loss of lung function. In order to examine how the virus causes inflammation, many earlier studies have used experimental infection with the virus and have measured various markers of inflammation. The purpose of this study is to compare the levels of inflammatory and remodeling products in the airways of study participants with mild to moderate asthma and healthy, non-asthmatic subjects after infection with rhinovirus (the common cold virus).
This aim of the study is to evaluate the effect of nebulized nitroglycerin on echocardiographic (biventricular function, pulmonary artery pressure, PDA and PFO shunting and tissue doppler imaging) and clinical parameters (Oxygen saturation index, heart rate, blood pressure, mean airway pressure, ventilation setting) in patients with PPHN.
