NCT02463773
This is a proof of concept study where the investigators aim to study the correlation between the use of a simple bedside ultrasound measurement of diaphragmatic muscle excursion with established (but time consuming) measurements made to optimize an important setting on the mechanical ventilator (positive end expiratory pressure or PEEP) in intubated adults with acute respiratory distress syndrome (ARDS) in the medical ICU.
NCT04958577
This study will evaluate the accuracy of the condition suggestions and urgency advice of the Swahili language Ada symptom assessment application (SAA), when symptoms are input by a lay-person user and a medical professional; these SAA results will then be compared to the condition suggestions and urgency advice of different tiers of doctors and a "gold standard" created by a panel.
NCT04955756
Early identification and Severity prediction of Acute Respiratory infectious disease has become a top priority for clinicians at department of infectious and respiratory diseases after COVID-19 broke out. This is a multicenter, prospective, and randomized study, which aims to figure out the best way of early identification and severity prediction of acute respiratory infectious diseases. Patients with suspected acute respiratory infectious diseases will be enrolled into this study and received two different diagnostic pathways.
NCT04497454
This is a prospective, randomized, single-center, open-label controlled trial, designed to compare the efficacy of two ventilation strategies (Low Tidal Volume and positive end-expiratory pressure (PEEP) based on the Acute Respiratory Distress Syndrome (ARDS) Network low PEEP-fraction of inspired oxygen inspired oxygen fraction (FIO2) Table versus Low Driving Pressure and PEEP guided by Electrical Impedance Tomography (EIT) in reducing daily lung injury score in patients with acute respiratory distress syndrome caused by COVID-19. The two strategies incorporate different prioritizations of clinical variables. The PEEP-FIO2 table strategy aims to reduce lung overdistension, even if it requires tolerating worse gas exchange. EIT-guided strategy prioritizes mechanical stress protection, avoiding alveolar overdistension and collapse.

To compare the pharmacokinetics of budesonide delivered by BDA MDI to budesonide delivered by Pulmicort Respules in children with Asthma aged 4 to 8 years.
NCT04955327
Conventional therapy of upper respiratory tract infection (URTI) is not always effective and sometimes leads to side effects and also to inappropriate use of antibiotic. Hence, a search for safe and effective further treatment options is justified and would be a welcome addition to available conventional treatment. Use of plant based dietary supplements has become increasingly popular over the last few decades or so. Research based on some plants is more than centuries old and its main therapeutic objective is to stimulate the self-healing power of the body. Andrographolide was docked successfully in the binding site of SARS-CoV-2 Mpro. Computational approaches also predicts this molecule to have good solubility, pharmacodynamics property and target accuracy. This molecule also obeys Lipinski's rule, which makes it a promising compound to pursue further biochemical and cell based assays to explore its potential for use against COVID-19. A. Paniculata is a patented extract, standardized to Andrographolide, 14-deoxyandrographolide, and Neo-andrographolide. Maqui contains Maqui Berry Extract of Aristotelia Chilensis (10% Anthocyanidin, 8% Delphinidin) belonging to the family of Elaeocarpaceae, which has been known for its use in several conditions such as sore throat, fever and several other ailments. In the present study, the therapeutic potential of Andrographis Paniculata and Aristotelia chilensis as single ingredients as well as in combination will be evaluated in participants with common cold and COVID related symptoms. The products to be evaluated have been rigorously standardized and are available under the brand names of A. Paniculata and A. Chilensis. Literature indicates that both A. Paniculata and A.Chilensis are effective and safe in the treatment of typical cold-related symptoms in adults.

NCT03397940
Summer vacation is a 3-month window of vulnerability for children from low-income households when health behaviors and academic learning decay. The goal of this project is to collect information on where low-income children go during summer, what they do when they get there, and how their behaviors (physical activity, sedentary, sleep, and diet) differ between the summer (unstructured days) and school year (structured days). This study is 1) significant because it will provide evidence on potential points of intervention that can reduce or reverse the excessive unhealthy weight gains that occur during summer and 2) innovative because it will be the first to identify changes in activity, sedentary, sleep, and dietary behaviors during prolonged and shorter periodic breaks from school and link these behaviors to changes in zBMI over time.
NCT04633720
In children under 6 years of age undergoing regular surgery during general anesthesia, the intratidal compliance profile is evaluated when different tidal volumes are applied at different positive end expiratory pressures. Then determine the most appropriate combination of positive end-tidal pressure and tidal volume.
NCT05363332
Critically ill COVID-19 patients with acute respiratory failure, in the intensive care unit (ICU), often feature high respiratory drive, determining large inspiratory efforts resulting in high pressures and global and regional over-distention, leading to lung injury. SARS-CoV-2 neurotropic-penetration in control centers in medulla oblongata might contribute to dysregulation and to excessively high respiratory drive observed in these patients. These pathophysiological conditions may often lead to the development of patient-ventilator asynchronies in aptients under mechanical ventilation, again leading to high tidal volumes and increased lung injury. These phenomena can contribute to prolonged duration of mechanical ventilation and ICU length of stay, but also can result in long term adverse outcomes like emotional/psychological and cognitive sequelae. All them compromising the quality of life of critically ill survivors after ICU discharge. The investigators will conduct a multicenter study in adult critically ill COVID-19 patients with hypoxemic respiratory failure, aiming to: 1) characterize incidence and clustering of high respiratory drive by developing algorithms, 2) apply artificial intelligence in respiratory signals to identify potentially harmful patient-ventilator interactions, 3) characterize cognitive and emotional sequelae in critically ill COVID-19 survivors after ICU discharge and 4) identify sets of genes and transcriptomic signatures whose quantified expression predisposed to asynchronies and cognitive impairment in critically ill COVID-19 patients.
NCT05363098
Mechanical ventilation (MV) is a life-saving supportive therapy and one of the most common interventions implemented in intensive care. To date, only the inspiratory phase of breathing has been extensively investigated, and new MV methods have been implemented to reduce its harmful effects. Despite this, lung injury still occurs and propagates, causing multiorgan failure and patient deaths. The expiratory phase is considered unharmful and is not monitored or assisted during MV. In animal experiments, we recently showed that the loss of diaphragmatic contraction during expiration can harm the lungs during MV. During mechanical ventilation, the expiratory phase of breathing is completely disregarded. However, in all conditions that promote lung collapse, peripheral airways gradually compress and close throughout the expiration, potentially worsening lung injury. This cyclical lung collapse and consequent air-trapping may have an impact on the Starling resistor mechanisms that regulate venous return from the brain, potentially affecting cerebral perfusion and intracranial pressure. This study will investigate the incidence and the consequences of an uncontrolled expiration and expiratory lung collapse in spontaneously breathing critically ill neurosurgical patients during mechanical ventilation. Electrical impedance tomography measurements , oesophagus and gastric pressure, electrical activity of the diaphragm and intracranial pressure will be acquired in a synchronised manner during controlled mechanical ventilation, on a daily bases during assisted mechanical ventilation.
