NCT03683927
Pneumonia and diarrhea are the most frequent causes of infectious diseases in children under 5 years of age worldwide, responsible for 1.5 million deaths annually. In up to 80% of pneumonia cases the etiology is viral. Some viruses can persist up to 6 months after an acute infection. The time when viruses enter the body and whether they are commensals or only cause disease and are eliminated after an acute infection is unknown. Modern techniques have identified diverse communities of microbiota in healthy and sick people, and viral communities associated in a close interaction. The acquisition and colonization by respiratory viruses and the role in health and disease in this niche that is the microbiome is unknown. The role of probiotics in the prevention of respiratory disease and in the maintenance of homeostasis in the microbiota is poorly understood, and even more the probable relationship between the microbiota, the respiratory viruses that could be commensals or pathogens at the respiratory level, the time when children can be colonized, and their regulation with the administration of probiotics. The aims of the study are to determine the changes in the intestinal and respiratory microbiota, the viruses that can be commensals or cause disease and the role of probiotics in the prevention of respiratory diseases during the first year of life. A prospective, randomized, controlled clinical trial will be carried out making basic metagenomics studies (translational medicine). After informed consent, 120 newborns will be randomized into 2 groups, one will receive probiotics 4 times a week orally and the other a placebo consisting of sterile water 4 times a week. The clinical follow up will be done every 2 months until 1 year old, nasal washes and stool samples will be collected to determine the intestinal and respiratory microbiome. Multiplex polymerase chain reaction studies will be conducted to detect the presence of respiratory viruses and the time when the children acquire viruses that are commensal or only in the case of respiratory infection. The mothers will be asked to come for consult in case of respiratory infection and a nasal wash and stool sample will be taken. Descriptive, bivariate and multivariate statistics will be used to determine the associations between the microbiota, the viral metagenomics, the respiratory viruses and the risk of presenting or not respiratory infection in the group receiving probiotics compared to placebo.
NCT03684759

Participants will receive 1 dose of presatovir on Day 1 and followed for 27 days postdose. Nasal swabs will be collected at each study visit (excluding Day 28) and assayed for change in viral load as the primary endpoint.
NCT03680976
The purpose of this study is to demonstrate the efficacy and safety of 10-nitro-9(E)-octadec-9-enoic acid (CXA-10) in obese adult asthmatics. The study's hypothesis is that 150 mg/day of CXA-10 for 12 weeks will alleviate obesity-related airway hyper-reactivity in obese adult asthmatics.
NCT02114398
The study aim is to compare usual asthma crisis treatment of hospitalized children with usual treatment associated to sophrology.
NCT03121781
Preterm babies have immature lungs and frequent pauses in their breathing which often necessitates breathing support. Nasal Continuous Positive Airway Pressure (nCPAP) is one of the most commonly used tools, but the standard interfaces (prongs or mask) may cause nasal-septal injury and discomfort. The RAM cannula is another interface that consists in soft and curved prongs to avoid this nasal injury, but as the seal is not 100%, suboptimal delivery of airway distending pressure could result if they are used to deliver CPAP, as compared to standard interfaces. The investigators plan to study very low birth weight preterm babies who are generally well but require some support with their breathing. By inserting a special feeding tube with sensors into the stomach, the investigators can measure the electrical activity of the diaphragm (EAdi), which is an important muscle for breathing. By analyzing EAdi in babies receiving nCPAP either with prongs or ram cannula, the investigators will be able to measure and compare how each method of support affects a baby's breathing. This important study will help us determine the most appropriate breathing support for preterm babies.
NCT03356288
This study will test the use of a new handheld device (called the N-Tidal C), that measures a person's tidal breath carbon dioxide, in diagnosing the cause of someone's breathlessness. It will also evaluate whether this device can detect when a person's breathing problem is getting worse.
NCT01114581
The purpose of this research study is to explore the mechanism of action of Mucinex, an oral, over-the-counter, FDA approved expectorant in patients with acute respiratory tract infections.
NCT02602067
Tenatumomab is a Sigma-Tau developed new anti-Tenascin antibody. It is a murine monoclonal antibody directed towards Tenascin-C. By means of this antibody, Tenascin-C expression was studied on a commercial tissue array slides each carrying malignant breast, colorectal, lung, ovarian or B and T cell Non-Hodgkin Limphoma tissue sections. All these cancers type showed positivity to Tenascin-C between the 64% and 13.3%. Consequently, Sigma-tau is exploring the use of the 131I-labeled Tenatumomab for anti-cancer radioimmunotherapy.
NCT03026322
Complications are common during endotracheal intubation of critically ill adults. Manual ventilation between induction and intubation ("bag-valve-mask" ventilation) has been proposed as a means of preventing hypoxemia, the most common complication of intubation outside the operating room. Safety and efficacy data, however, are lacking. PreVent is a randomized trial comparing manual ventilation between induction and laryngoscopy to no manual ventilation between induction an laryngoscopy during endotracheal intubation of critically ill adults. The primary efficacy endpoint will be the lowest arterial oxygen saturation. The primary safety endpoints will be the lowest oxygen saturation, highest fraction of inspired oxygen, and highest positive end-expiratory pressure in the 24 hours after the procedure.
NCT01922648
Respiratory Syncytial Virus (RSV) is a virus that causes chest infections. It is the single most important cause of severe respiratory illness in infants and young children, and severe RSV infection early in life is associated with an increased risk of later developing asthma. RSV also causes severe disease in elderly and immune-compromised adults, and the amount of RSV disease in the elderly is similar to that from seasonal flu. The virus is transmitted in the secretions of the upper respiratory tract of infected individuals and by contact with contaminated surfaces (such as toys). Hospital outbreaks, especially on paediatric and neonatal wards, are not uncommon. Infection by RSV does not develop a natural long-lasting protection against re-infection (like, for example, measles does). In the USA nearly all children by 24 months of age have been infected at least once with RSV, and about half will have experienced two infections. There is no effective anti-viral drug to treat an infection and the only way of managing cases of severe infection is through supporting organs, such as the lungs, to withstand and recover from the illness. There remains a real need to develop an effective vaccine to prevent severe infections caused by RSV. A better understanding of the way the immune system responds to RSV in children would aid the development of such a vaccine. The purpose of this study is to increase our understanding of how the immune system responds to RSV. Only limited data is available on some important components of the immune response and this study is designed to measure these in more detail. This is done using a single blood sample. A total of 35 children are anticipated to be recruited to this study, at ages when we expect to see differences in the immune response to RSV; * 5 infants aged between 2 and 4 months (Group 1), who have not yet been exposed to RSV * 20 infants aged between 6 and 12 months (Group 2), who will have had exposure to one single RSV season in the winter of 2011/12 * 10 children aged between 3 and 6 years (Group 3), who have been exposed to RSV over several winter seasons
NCT03151226
Non emergent scheduled cesarean sections will be consented to participate in this study of patients who have screened negative for obstructive sleep apnea and who are also BMI\>/= 35 to have capnography monitoring postoperatively. The capnography and pulse oximetry will be initiated in the post anesthesia care unit and be worn for 12-24 hours after delivery. Data will be retrieved after that time period in a deidentified fashion. Medication usage will be reviewed as well as the standard of care information from the duramorph monitoring will be retrieved.

NCT01866306
The purpose of this study is to establish the safety and tolerability of Unbiased Biomarkers for the Prediction of Respiratory Disease Outcomes (U-BIOPRED) human rhinovirus 16 (RV16UB) in healthy and asthmatic participants, and to identify an appropriate dosage of RV16UB in order to study biomarkers in asthmatic participants. The study is divided into 2 parts. Part 1 is a dose-finding study where healthy participants, and asthmatic participants, who were either treated or not treated with a class of long-acting beta antagonists (LABA) will be recruited to undergo nasal challenge with increasing doses of RV16UB. Part 2 is a biomarker study where mild to moderate asthmatics undergo challenge with the most appropriate dose of RV16UB identified in Part 1, based on tolerability and viral effects. .
