Filter by:Objectiv: To compare the effect of intratracheal administration of surfactant vs. surfactant/budesonide on the incidence of bronchopulmonary dysplasia in preterm infants less than 34 weeks of gestation. Material and methods: Study design: Double-blind randomized controlled clinical trial.Inclusion criteria: Newborns under 34 weeks of gestation with a diagnosis of Respiratory Distress Syndrome requiring administration of surfactant, invasive and/or non-invasive ventilatory support admitted to the Neonatal Intensive Care Unit service and pathological nursery. Procedure: 328 patients will be included from Group A: 164 patients, from Group B: 164 patients who meet the selection criteria within the first 4 hours of hospital stay, after the authorization of the parents or guardian signing the informed consent. According to the assigned group, the preparation of surfactant or surfactant/budesonide in the syringe will be carried out, prior to performing the tracheal cannulation procedure. Group A will be given surfactant (beractant, lung phospholipids of bovine origin. Injectable suspension 1ml contains 25mg) at a dose of 100mg/kg or 4ml/kg and budesonide (budesonide, nebulized suspension 2ml contains 0.500mg) at a dose of 0.250 mg/kg or 1 ml/kg. Group B will receive surfactant alone (beractant, lung phospholipids of bovine origin. Injectable suspension 1ml contains 25mg) administered at a dose of 100mg/kg or 4ml/kg. Subsequently, follow-up will be carried out at 12 hours to assess the administration of the second dose of surfactant, type of mechanical ventilation, inspired fraction of oxygen (Fi02), arterial pressure of oxygen (PaO2), partial pressure of carbon dioxide (PaCO2 ), mean airway pressure (PMVA), oxygen index (IO), oxygen saturation by pulse oximetry, weekly follow-up of the patient will continue for 28 days, evaluating the same parameters to make a diagnosis of bronchopulmonary dysplasia and finally at 36 postmenstrual weeks of gestation in those under 32 SDG or at discharge and at 56 postmenstrual days of life in those over 32 SDG or at discharge, allowing the severity of the disease to be determined.Sample size: The study includes an intervention group (surfactant/budesonide group) and a control group (surfactant only group), each with 164 patients, for a total of 328 patients. Statistical analysis: The Chi-Square statistician will be used with a precision requirement of 95%, where p<=0.05. The risk measurement will be with RR (RR) and its 95% confidence interval (CI). NICSS 2007 statistical package will be used. Ethical aspects: This study must have an authorization signature through informed consent.
The purpose of this retrospective study is to evaluate the effectiveness of CPM nasal spray as part of the treatment of COVID-19 and its impact on clinical symptoms. Two cohort groups will be compared (CPM vs. standard care). The hypothesis to be tested is that patients treated with CPM nasal spray showed more rapid clinical improvement than those treated with standard of care alone. Clinical improvement will be evaluated by the total number of days with the manifestation of COVID-19 symptoms, including cough, nasal congestion, ageusia, and anosmia, among others. The rate of hospitalization between the cohorts will also be evaluated.
There are many techniques that can allow for the quantification of lung function in children; some are being used clinically and others are under development. Many of these tools are available at BC Children's Hospital. This registry study will act as a central repository for the results of traditional and novel pulmonary function tests done at BC Children's Hospital to allow for future analysis.
A randomized controlled trial comparing Noninvasive high frequency oscillatory ventilation (NHFOV) and Noninvasive positive pressure ventilation (NIPPV) as post-extubation respiratory support in preterm neonates with respiratory distress syndrome(RDS)
The investigators expect to reveal the association between air pollution and childhood respiratory diseases through a multi-center observational study, and summarize the relationship between air pollution and childhood respiratory diseases.
Symptoms such as cough, wheeze, and breathlessness are among the most common reasons for general practitioner or emergency department visits in the UK. Such symptoms have a profound impact on patients' ability to live a fulfilled life, often rendering people unable to work and socialise. Azithromycin (a type of antibiotic) improves symptoms and reduces flare-ups of diseases such as asthma and chronic obstructive pulmonary disease (COPD). The reason why it works is unclear. Many people believe that it either decreases the number of bacteria in the lungs or reduces inflammation in the lungs and the upper airways. Neither theory is proven. Another possible mechanism that has been much less studied is that Azithromycin encourages the body to move food and fluid through the gut more quickly, thus preventing reflux and aspiration of small food particles and stomach acid. It has been shown that lung damage can occur when gut contents enter the airways, which may contribute chronic lung disease patients' symptoms In this study the investigators will test the effect of azithromycin on the gut in patients with chronic lung diseases. The investigators will measure the strength of a patients swallow by measuring the pressures in their gullet, using high-resolution oesophageal manometry (HROM), before and after treatment, in people being started on azithromycin as part of their routine care. The investigators will also measure the effect that azithromycin has on their symptoms and observe whether there is a relationship between the strength of their swallow and their symptoms. At the end of this study, the investigators hope to better understand the way in which azithromycin helps to improve the symptoms of patients with chronic lung diseases. The investigators also hope to open the door to investigate the effect of other drugs that improve gut function in patients with chronic lung diseases.
The study is conducted in the context of the COVID-19 pandemic in general, and more specifically in the context of the evaluation of the use of protective masks as a barrier to the spread of the virus. The wearing of masks is one of the recommended barrier measures to limit the spread of the SARS-CoV-2 virus responsible for COVID-19. It is recommended in all circumstances, and mandatory in some. Regardless of the type of mask used (noting that the so-called "surgical" masks are by far the most common), there are various disadvantages associated with wearing them. Dyspnoea (unpleasant or upsetting perception of respiratory activity) is one of these disadvantages. It can lead to reluctance to wear the mask, or to the adoption of inappropriate practices that reduce its effectiveness. This "side effect" of the mask is more pronounced in patients with underlying respiratory diseases. However, not all mask designs are equivalent in terms of their physical properties, which can theoretically generate varying levels of dyspnoea. It is therefore important to determine which mask designs are more or less dyspnogenic, in order to guide the preferential use of certain designs in certain patient categories. The TOLMASK study (Tolerance of SARS-CoV2 Surgical Masks in Patients with Chronic Respiratory Diseases) is a prospective, randomised, triple-blind, single-centre study comparing several surgical masks in a crossover design. The primary objective of the study is to evaluate the respiratory tolerance of different surgical masks and the secondary objective is to evaluate their general tolerance.
This is a Phase 2, randomized, multi-center study in approximately 300 adults who received 2 doses of aH5N1c or placebo in and completed the parent study V89_18 in the <65 years of age cohort. The study investigates whether two priming doses of MF59-adjuvanted H5N1 cell culture-derived vaccine (aH5N1c) followed by one or two booster vaccinations with a MF59-adjuvanted H5N6 cell culture derived vaccine (aH5N6c) 3 weeks apart elicit immune responses to the antigens used for priming (H5N1) and boosting (H5N6) after first and second heterologous booster vaccination. Eligible subjects, who received 2 doses of aH5N1c in the parent study V89_18 are randomized in a 1:1 ratio to receive either two aH5N6c vaccinations, 3 weeks apart (group 1) or an aH5N6c vaccination on Day 1 and saline placebo on Day 22 (group 2). Eligible subjects, who received placebo in the parent study will receive two aH5N6c vaccinations, 3 weeks apart (group 3). After the second vaccine administration, subjects are monitored for approximately 6 months for safety and antibody persistence. The total study duration will be approximately 7 months per subject.
