Study Summary: Title: A Randomized Controlled Trial of Noninvasive Positive Airway Pressure in the Pediatric Emergency Department for the Treatment of Acute Asthma Exacerbations Principal Investigator: Thomas J. Abramo, MD Hypothesis: For acute moderate to severe pediatric asthma exacerbations the use of NIPPV/BiPAP, in conjunction with current standard of care therapies, will lead to a more rapid improvement in patient ventilation, faster resolution of respiratory distress and result in improved ventilatory parameters, secondary outcomes and pediatric asthma scores. Study Design: Prospective, randomized controlled trial Study Duration: This study will be conducted over a 36 month period. Sample Size: 240 subjects Population: Children ages 2-17 years of age presenting to the ED with Acute asthma exacerbation and a Pediatric Asthma Score (PAS) ≥ 8. Synopsis: Eligible subjects will be randomized to either a control group or study groups. The study groups will be either a NIPPV/BiPAP group. The subjects in the study groups will continue to receive all standard of care therapies per the asthma severity protocols. All nebulized therapies will be given through the NIPPV circuit. Patients will be assessed by the pediatric asthma score (PAS), measured respiratory parameters, volumetric end tidal carbon dioxide monitoring and measured cardiac parameters. Objectives: A. Evaluate if the use of NIPPV/BiPAP in conjunction with traditional inhaled beta-agonists improves the outcome in pediatric patients with acute moderate to severe asthma in the acute setting. B. Describe the physiology of NIPPV/BiPAP by measuring cardiac parameters in children randomized to a NIPPV group. C. Monitor safety of NIPPV/BiPAP use for acute asthma exacerbations in children. Safety A.: The study must be IRB approved. B.: Appropriate consent and assent documents will be obtained prior to enrolling the subject in the study. C.: A clear safety plan including DSMB will be established to monitor for adverse events. D.: Confidentiality will be ensured for all subjects enrolled in the study.

NCT05721183
The Norwegian Institute of Public Health (NIPH) is introducing a new electronic tool for direct observation of compliance with recommended infection prevention and control measures in healthcare. The solution is called the National Tool for Observation of Infection Prevention Measures (NOST). NOST is a quality improvement tool that includes a web-based solution for observing compliance with recommendations for hand hygiene and other IPC measures. Through NOST, healthcare personnel will be able to identify the local level of compliance, which in turn can reveal areas for improvement. This protocol includes the evaluation of NOST in hospitals. The evaluation is designed as a cluster-randomized controlled trial with two arms where eligible wards in hospitals are randomly allocated into an intervention and a control arm. NOST is implemented in the intervention wards at the start of the evaluation period, and compliance with hand hygiene and other outcomes are measured in both the interventions and control wards one year later. The objective of evaluating NOST is to: * measure if implementation of NOST leads to improved infection prevention and control in the form of increased compliance with hand hygiene recommendations, and * measure if changes in the quality of infection prevention and control as a result of implemented NOST affects the epidemiology of healthcare-associated infections in healthcare institutions and the length of hospital stays.
NCT05711966
The primary hypothesis of this study is that surfactant administration by INtubate-RECruit-SURfactant-Extubate (IN-REC-SUR-E), via a high frequency oscillatory ventilation recruitment maneuver increases survival without BPD at 36 weeks' gestational age in spontaneously breathing infants born at 24+0-27+6 weeks' gestation affected by Respiratory Distress Syndrome (RDS) and failing nasal CPAP or nasal intermittent positive pressure ventilation (NIPPV) during the first 24 hours of life compared to less invasive surfactant administration (LISA).
NCT03326830
The purpose of the present project is to compare High-Flow Nasal Oxygen therapy with Standard Oxygen therapy, initiated in the prehospital setting in patients with acute hypoxemia respiratory failure, in terms of oxygenation at arrival to the hospital and need of mechanical ventilation during the subsequent 28 days
NCT03503812
The MEDEA project is envisioned to provide the field-based evidence for the adoption of a strategic plan for mitigating the health effects of desert dust storm (DDS) events in South-Eastern Europe. Over the past decade, several studies have demonstrated that DDS in Mediterranean countries, originating mostly from the Sahara and Arabian Peninsula deserts, have been increasing in number and magnitude and linked it to desertification, climatic variability and global warming. EU legislation considers DDS impossible to prevent, implicitly harmless and discounts their contribution to daily and annual air quality standards of particulate matter up to 10 microns (PM10). However, there is increasing evidence from epidemiological studies, which correlates exposure to PM10 during DDS with a significant increase in mortality and hospital admissions from cardiovascular and respiratory causes. Therefore, there is a pressing need for EU policies to reduce population exposures and increase individual, population and institutional resilience to the growing frequency and intensity of DDS. MEDEA ultimate goal is to demonstrate the feasibility and effectiveness of an adaptation strategy to DDS and better inform EU policy making. The adaptation strategy will be carried out within two panel studies, with two different groups of patients; 1. Children with asthma and 2. Adults with atrial fibrillation (AF). The primary objective will be to quantify the vulnerability of children with asthma and adults with AF during DDS outbreaks and provide evidence-based estimates demonstrating which interventions/recommendations work best in mitigating adverse health effects in this group of patients after randomization of each group of patients to three parallel intervention groups: a) No intervention for DDS; b) Intervention for outdoor exposure reduction, and c) Interventions for both outdoor and indoor exposure reduction. The secondary objective of the study is to demonstrate which of the recommendations are effective in reducing outdoor and indoor exposures to DDS in a panel of children with asthma and in a panel of AF adults. Intervention: Each group of patients (children with asthma and AF patients) will be recruited and will be randomized during the high DDS outbreaks season (Spring 2019 and 2020) with 1:1:1 ratio into three parallel groups to receive: a) No intervention for DDS; b) Intervention for outdoor exposure reduction, by reducing the time spend outdoors and by avoiding physical activity and c) Interventions for outdoor (as above) and indoor exposure reduction (by minimizing home ventilation and filtering indoor air). Disease-related adverse health outcomes will be assessed in the three parallel arms of the study. Approaches for delivering the intervention: A bidirectional, patient-centered e-Platform will be developed in order to facilitate prompt communication with the participants and provide early warnings regarding forecasted upcoming DDS events through text messaging and smartphone applications. Furthermore, the same IT platform and mobile application will be utilised for the dissemination of the exposure reduction guidelines that the participants will follow. Assessment of adherence to intervention: 1.Monitor compliance to exposure-reduction guidelines using remote sensors. The intervention for outdoor exposure reduction, entailing reduction of the time spend outdoors and avoidance of physical activity, will be assessed with the use of smart wristwatches that will be equipped with Global Positioning System (GPS) and an accelerometer. 2.The intervention for indoor exposure reduction, entailing minimization of home ventilation and filtering of indoor air, will be assessed with the use of particle samplers that will be placed outside and inside of houses and school classrooms.
NCT03085069
This is an open-label, single-arm, multi-center, phase 2 Study to evaluate SHR-1210(anti-PD-1 antibody) in in adult Chinese patients with advanced or metastatic non-small cell lung cancer who failed or progressed to prior first-line systemic treatment. Enrolled subjects will be assigned to 4 cohorts on the basis of PD-L1 expression in tumor cells(\<1%, ≥1%-25%, ≥25%-50%, ≥50%) all will be treated with the standard SHR-1210 dose (200mg) , Q2W, until documented progressive disease (PD) occurs. Subjects will return to the clinic once every two weeks. Radiographic disease assessments will be performed every 6 weeks. The primary study hypothesis is that treatment with SHR-1210 improves Objective Response Rate when compare with standard second-line therapy, no matter how much PD-L1 expression in tumor.

The purpose of this study is to gain understanding of mechanisms whereby bariatric surgery modulates pulmonary inflammation and pulmonary microbiome composition and how these changes direct the pathobiology of human obese asthma.
NCT05729451
The aim of this observational study is to investigate the association between mid-life changes in cardiorespiratory fitness and the risk of breast cancer incidence and mortality among Swedish women. The main questions to answer are: \- Are changes in cardiorespiratory fitness associated with the risk of being diagnosed or dying from/with breast cancer later in life? Participants performed at least two occupational health assessment tests, which consisted of a submaximal ergometer cycle test, measurement of body mass and height to calculate BMI, and a questionnaires on physical and life style habits.
NCT05726500
The goal of this clinical trial is to evaluate regional ventilation distribution in patients admitted to the intensive care unit after emergent laparotomy due to abdominal sepsis. The main question it aims to answer is: • evaluate if patients admitted after an open abdomen strategy have a different regional ventilation distribution compared to patients in which abdomen is closed at the end of the procedure Participants will undergo non-invasive monitoring (esophageal pressure and electrical impedance tomography) and an blood gas analysis samples. Researchers will compare open abdomen group and closed abdomen group to see if the ventilation distribution pattern is different.
NCT04656587
The investigators aim to study the effect and safety of bilevel positive airway pressure (BPAP) in children with moderate to severe asthma exacerbations - by examining the effects of early initiation of BPAP in pediatric patients who present to the emergency room with a moderate to severe asthma exacerbation. The study is interested in how early initiation of BPAP affects PRAM scores, vital signs, as well as the total duration of continuous albuterol in the patient population.
NCT01097954
Exercise induced bronchospasm (EIB), also known as exercise induced asthma (EIA) is a transient obstruction to airflow triggered by exertion. It is now a well known identity, center of discussion in recent years, particularly in the athletes' world. It is more common in asthmatic individuals (regardless of severity of disease), but it is also seen in otherwise healthy subjects, leading to the general consensus that the pathophysiology is different than asthma. The concentration of exhaled nitric oxide (FeNO) in various airway \& respiratory disorders, particularly asthma, has been deeply studied. Its use for noninvasive monitoring of asthma control (reflecting airway eosinophilic inflammation) is being closely examined and put into clinical practice. FeNO is significantly elevated in asthma. Elevated FeNO levels have also been noted in patients hospitalized with a COPD exacerbation, acidosis, rhinitis, bronchiectasis, active pulmonary sarcoidosis, active fibrosing alveolitis, and acute lung allograft rejection. Decreased FeNO levels have been seen in patients with primary ciliary dyskinesia, cystic fibrosis, PiZZ phenotype-related alpha-1 antitrypsin deficiency, and pulmonary hypertension Two studies have addressed the variations on FeNO after EIB and they had contradictory results. Scollo et al. found no change in FeNO in either healthy or asthmatic children after a 6-min of vigorous exertion in an exercise laboratory when they studied 24 asthmatic and 18 control children. Terada et al. reported, for 39 subjects, a decrease in FeNO in subjects with EIB and an increase in healthy controls. It is well accepted that the pathophysiology of exercise induced bronchospasm it is not similar to that of asthma. Certainly the inflammation in the airway does not appear to be eosinophilic. Understanding the disease mechanism is a key factor to adequately manage it. This will be a prospective study measuring online exhaled nitric oxide involving children 8 to 21 years old. The study group will include any children coming for a pulmonary exercise test in the exercise laboratory located in the Pediatric Pulmonary Division office. The study will be conducted from the fall of 2009 until the spring of 2011. The change in the FeNO measurement will be correlated with the change in % predicted FEV1. We will consider significant a decrease in FEV1 post exercise of 15% and/or decrease on FEF25-75 of 20% that will persist until 15 minutes after completing exercise. We will also record any symptoms reported by the subject during or after the test. An exercise test is a standard of care when suspecting exercise-induced asthma. The subjects and their parents coming for exercise test will be offered the opportunity to participate in the study. The subject will come for the exercise test and will perform spirometry and FeNO measurement prior to start the test. According to our exercise laboratory protocol 1 minute of warm up at a low speed, followed by 6 minutes of high speed (enough to increase heart rate to 90% predicted or more) and 3 minutes of cool down at a low speed will be performed. Then spirometry will be repeated at 3, 5, 10 and 15 minutes and FeNO measurement will be taken at 5, 10 and 15 minutes. We will analyze the data to find if there is any significant change in FeNO measurements after exercise.

Starting from December 2019, novel coronavirus disease 2019 (COVID-19) pandemic has caused a tremendous economic loss and unprecedented health crisis across the globe. Discovering an effective and safe drug candidates for the treatment of COVID-19 and its associated symptoms became a global urgent demand especially due to limited data that have been released regarding the vaccine efficacy and safety in humans. Reviewing the recent research, Olive leaf was selected as a potential co-therapy supplement for the treatment and the improvement of clinical manifestations in COVID-19 patients. Olive leaves reported to be rich in phenolic compounds such as oleuropein, hydroxy tyrosol, verbascoside, apigenin-7-glucoside and luteolin-7-glucoside which has been reported as anti-SARS-CoV-2 metabolites in recent In silico, computational and in vitro studies. In addition, olive leaf extract was previously reported in several in vivo studies for its anti-inflammatory, analgesic, antipyretic, immunomodulatory and anti-thrombotic activities which is of a great benefit in the control of associated inflammatory cytokine storm and disseminated intravascular coagulation in COVID-19 patients. A placebo-controlled, randomized clinical trial at Fayoum University Hospital in Egypt will be conducted. RT-PCR confirmed COVID-19 adults showing mild to moderate disease will be enrolled in the study. Patients presenting with multi-organ failure, ventilator support, and chronic diseases (except diabetes mellitus and hypertension) were excluded. Patients were randomly assigned in 1:1 ratio to receive standardized olive leaves capsules (containing 20-50% oleuropein) or placebo up-to 10 days along with standard care. The expected outcomes included symptom alleviation, viral clearance, improvement of analysis (CBC, CRP, LDH, ESR, Ferritin, D-dimer, creatinine, ALT and AST) and a 10-day mortality in intention-to-treat population.

NCT02596087
The overall goal of the IQ-MAPLE project is to improve the quality of care provided to patients with several heart, lung and blood conditions by facilitating more accurate and complete problem list documentation. In the first aim, the investigators will design and validate a series of problem inference algorithms, using rule-based techniques on structured data in the electronic health record (EHR) and natural language processing on unstructured data. Both of these techniques will yield candidate problems that the patient is likely to have, and the results will be integrated. In Aim 2, the investigators will design clinical decision support interventions in the EHRs of the four study sites to alert physicians when a candidate problem is detected that is missing from the patient's problem list - the clinician will then be able to accept the alert and add the problem, override the alert, or ignore it entirely. In Aim 3, the investigators will conduct a randomized trial and evaluate the effect of the problem list alert on three endpoints: alert acceptance, problem list addition rate and clinical quality.
NCT04290871
The investigators will enroll 104 patients with severe COVID-19 infection that mechanical ventilation is needed for respiratory support. Patients will be randomized to receive either inhaled nitric oxide (per protocol) or a placebo. ICU Standards of care will be the institution's own protocols (such as ventilation strategies and use and dose of antivirals and antimicrobials, steroids, inotropic and vasopressor agents).
NCT04062422
Height measurement is unreliable when neuromuscular weakness or spinal deformity is present. The aim of this study was to accurately predict pulmonary function from a limb segment (ulna) measurement that is precise and reproducible. Equations are available in caucasian children but are not available in children of sub-saharian or caribbean ethnicity, which was the aim of the study. To this end, 350 black children referred for pulmonary function testing for asthma follow-up will be included.
NCT01470755
In older children and adults, bronchodilator (BD) dose-effect relationship is part of the characteristics of asthma disease. There are no data on BD dose-response relationship in wheezy preschool children whose disease pathophysiology is poorly understood, but may, in part, takes on the characteristics of asthma. The investigators assume that 1) in young children interrupter resistance (Rint) could be used to measure a BD effect 2) the response to BD may vary depending on the dose used 3) the dose-response relationship could depend on the environment and gene polymorphism ADBR2. This is a prospective phase II study on dose-response relationship and description of the dose-response curve design using a "sparse" and a modeling approach MCP-Mod. The dose-response relationship will be modeled by sparse data. The investigators will test two doses per child in four designs that will be drawn. These doses will be assessed using Rint technique by a person blinded to the actual dose delivered to the child. Measurements of 90 children will estimate E0, Imax and D50 (pharmacokinetic constants) with an accuracy of 3.5%, 8.9% and 25.7% respectively. The bronchodilator used in the study is the Salbutamol as Ventolin ® (GSK) suspension for inhalation as an aerosol at a dose of 100μg per puff. Ventolin ® is used as part of the MA (No. 344 387-3)
NCT05137795
Brief Summary: SARS-CoV-2 virus infection is known to cause Lung Injury that begins as dyspnea and exercise intolerance, but may rapidly progress to Critical COVID-19 with Respiratory Failure and the need for noninvasive or mechanical ventilation. Mortality rates as high as 80% have been reported among those who require mechanical ventilation, despite best available intensive care. Patients with severe COVID-19 by FDA definition who have not developed respiratory failure be treated with nebulized ZYESAMI™ (aviptadil acetate, a synthetic version of Vasoactive Intestinal Polypeptide (VIP)) 100 μg 3x daily plus Standard of Care vs. placebo + Standard of Care using an FDA 501(k) cleared mesh nebulizer. The primary outcome will be progression in severity of COVID-19 (i.e. critical OR severe progressing to critical) over 28 days. Secondary outcomes will include blood oxygenation as measured by pulse oximetry, dyspnea, exercise tolerance, and levels of TNFα IL-6 and other cytokines.
