NCT04930978
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the causative agent of the Coronavirus disease (COVID-19). Tuberculosis (TB) is the foremost cause of infectious deaths globally. In 2025, an additional 1.4 million TB deaths could occur as direct consequence of the COVID-19 pandemic. It is postulated that individuals with latent or active TB are more susceptible to SARS-CoV-2 disease and that COVID-19 disease rate is high in patients with active TB, although the evidence is still scarce. TB and SARS-CoV-2 are both infectious diseases which primarily attack the alveolar region of the lungs and share common symptoms. SARS-CoV-2 disease can induce innate and adaptive immunity, but uncontrolled inflammatory innate immunity and impaired adaptive immune responses may be associated with severe tissue damage, both locally and systemically. People with coinfection (COVID-19 and TB disease) might potentially have impaired protective immune responses and treatment outcomes, specifically as far as anti-tuberculosis treatment is concerned. However, very little is known about the immunological underpinnings in this interface between TB and COVID-19 on the effect of SARS-CoV-2 disease on disease severity, response to treatment and treatment outcomes in pulmonary tuberculosis. Investigators hypothesize that altered immunity due to prior or present asymptomatic disease with SARS-CoV-2 virus can lead to altered immune responses and systems biology, increased severity and altered treatment outcomes in TB disease. The main objective of the study would be to evaluate the baseline differences in immune cells populations immune cell responses at baseline and at the time of treatment (2nd month) and end of treatment. Further, Investigators would be evaluating the changes in proteomic profiles in a subset of these individuals. In addition, immunological assays examining differences in T cell populations, measuring levels of various cytokines and by immunophenotyping as well as other immune parameters related to innate and adaptive responses will be performed to enhance the understanding of the immunological cross-talk between active TB patients with or without SARS-CoV-2. The secondary objective would be to study the clinical features, disease severity, mycobacterial burden and treatment outcomes in a cohort of SARS-CoV-2 infected (asymptomatic PCR or Antibody+) and non-infected patients with active pulmonary TB.
NCT05459012
Pregnancy may impact treatment adherence in women with asthma. This is a major risk factor for asthma exacerbation, which may have an important impact for both women and the babies. This study aims to evaluate the impact of a targeted patient education action tailored for pregnant women with asthma.
NCT06141161
Asthma is a significant public health threat, affecting more than 300 million individuals globally. Asthma is classified as a non-communicable disease and leads to reduced quality of life, poor physical functioning and reduced emotional well-being. The impact of this disease can be widespread and extends beyond the person living with the disease, affecting the lives of their family members, carers, communities and the health care system (1). Asthma is a variable chronic respiratory condition. It is characterized by symptoms of wheeze, cough, chest tightness, dyspnea and backed by variable airflow limitation, airway inflammation and airway hyper-responsiveness (AHR). The severity of asthma varies considerably, both between individuals and within individuals over time. Some people may have intermittent asthma and others may experience severe, potentially life-threatening disease (2, 3,4).

NCT06134674
The goal of this observational study is to determine the relationship between the nutritional profile of critically ill patients diagnosed with COVID-19 and disease severity, prognosis, and survival, to assess the ability to meet nutritional goals, EN complications, and reasons for discontinuation and postponement of feeding. The main questions aim to answer are the relationship between the duration of EN initiation and Prognostic Nutritional Index (PNI) score, neutrophil-lymphocyte ratio (NLR), oxygenation status, MV, ICU, and length of hospital stay, overall mortality, and whether nutritional goals were met, EN complications, and reasons for discontinuation and postponement.
NCT04106128
The diaphragm is a fine striated muscle with both extra respiratory and respiratory functions. It does most of the breathing work in interaction with the accessory respiratory muscles, the rib cage and the abdomen. Its activity can be measured by the transdiaphragmatic pressure generated by the magnetic stimulation of phrenic nerves (gold standard). It has been shown in the literature that diaphragmatic ultrasound, via the measurement of diaphragmatic excursion and especially the thickening fraction, is an easily accessible, non-invasive, reproducible and relevant technique for evaluating acute diaphragmatic dysfunction in resuscitation patients. The objective of this project is to evaluate the prevalence of diaphragmatic dysfunction at admission in patients hospitalized in intensive care / respiratory intensive care unit for hypercapnic and/or hypoxic acute respiratory distress and requiring ventilatory support by non-invasive ventilation or high flow oxygen therapy. A subgroup analysis will then be carried out on 3 populations: * Hypercapnic exacerbation of chronic obstructive pulmonary disease * Hypoxic acute respiratory distress on infectious lung disease * Acute pulmonary edema

NCT01893554
Human respiratory syncytial virus (RSV) is a common cause of respiratory illness in infants and children around the world. This study will evaluate the safety and immune response to a RSV vaccine in three groups of participants: healthy children who have already had an RSV infection (RSV seropositive), healthy infants and children who have not already had an RSV infection (RSV seronegative), and healthy younger infants who have not been screened for prior RSV infection.
NCT06118619
The main purpose of testing: To confirm the effectiveness and safety of the drug Ingaron when used in patients hospitalized at the research center for various reasons.
NCT04184609
The overall objective of this study is to better understand the respiratory mechanisms provoking dyspnea on exertion in obese asthmatic children.
NCT02772081
This study compared the administration of porcine surfactant (poractant alfa, Curosurf®) through a less invasive method (LISA), using a thin catheter, CHF 6440 (LISACATH®), during non-invasive ventilation (CPAP, NIPPV, BiPAP) with an approved conventional surfactant administration during invasive ventilation followed by rapid extubation in terms of short term and mid-term safety and efficacy in spontaneously breathing preterm neonates who have clinical signs of respiratory distress syndrome (RDS).
NCT03582930
Surfactant replacement therapy can be life-saving for newborn infants born with symptomatic lung surfactant deficiency causing Respiratory Distress Syndrome (RDS). Currently, such therapy requires instillation of a liquid suspension into the trachea through an endotracheal tube. Endotracheal intubations have undesirable adverse effects on fragile premature infants. Instilling surfactant as a liquid suspension into the lung is associated with adverse events due to interruption of breathing in patients who already have respiratory insufficiency. This treatment protocol is expanded access that offers the opportunity for patients to receive aerosolized Infasurf prior to FDA acting on ONY Biotech's application for approval for commercial marketing of aerosolized Infasurf.
NCT03693885
Spontaneous vaginal delivery of a healthy infant provokes a unique surge in stress hormone concentrations (e.g. AVP (arginine vasopressin) /copeptin) incommensurable with child or adult levels measured in any other situation. In contrast, infants delivered by primary caesarean section without preceding labour have low stress hormone concentrations at birth unless other stressors are present, including chorioamnionitis or intrauterine growth restriction. Infants delivered by caesarean section after a trial of labour show copeptin concentrations between these two extremes. Objectives:1) To reduce neonatal respiratory morbidity and admission to the Neonatal Intensive Care Unit and increase bonding and breastfeeding by triggering uterine contractions prior to planned caesarean delivery. 2\) To collect prospectively weight data of infants in the first 6 months of life to validate and expand our online neonatal weight calculator. Study design: Open label; randomised, placebo controlled trail Intervention: Oxytocin challenge test (OCT): Infusion of oxytocin 5 IU/500 ml Ringer® lactate at a rate of 12 ml/h and doubled every 10 min until three uterine contractions per 10-min interval are induced, at which point it will be stopped. Primary endpoint: \- Incidence of neonatal respiratory morbidity Secondary endpoints: * Umbilical cord blood copeptin levels * Postnatal neonatal weight change * Breastfeeding status
NCT06047405
The goal of this study is to compare two different modes of noninvasive ventilation in hypercapnic respiratory failure. The investigators will compare AVAPS and BIPAP S/T and hypothesize that AVAPS will result in a decreased length of stay in the ICU or on telemetry. Currently, noninvasive ventilation is the standard of care for hypercapnic respiratory failure. However, the most effective mode for patients with hypercapnic respiratory failure is unclear.

Approximately 180 patients from the US will be enrolled in this study.
NCT03263130
The purpose of this cross-sectional, observational study is to evaluate the site and mechanism(s) for expiratory airflow limitation in chronic, treated, current or former smokers (\>15 pack years) with COPD, Emphysema, and Asthma-COPD Overlap with mild to severe expiratory airflow limitation. Treatment may include short and long acting inhaled beta2agonists, short and long acting inhaled muscarinic receptor antagonists, inhaled and or oral corticosteroid, oral antibiotic, supplemental oxygen, and PDE type 4 inhibitor. In some cases, the patient may have had a history of asthma preceding the development of COPD (Asthma COPD Overlap).
NCT05301322
The purpose of this study is to assess the safety and immunogenicity of RSVpreF when coadministered with SIIV compared to sequential administration of the vaccines when given 1 month apart (SIIV followed by RSVpreF). Additionally, the study will contribute data supporting the development of RSVpreF as a prophylactic vaccine against RSV disease in infants through maternal immunization and in older adults through active vaccination.
NCT05465226
Pain after acute burn injury is complex with much still not understood. The primary mechanism is believed to be nociceptive, but is interwoven with aspects of somatogenic, neuropathic, and psychogenic pathways. As such, opioid receptor agonists are an essential component for pain management after burn injury. The majority of wound care and dressing changes are completed in non-intubated patients and rates of respiratory depression concerning. Oliceridine is a biased, selective MOR agonist approved for treatment of acute pain. To date there is no literature of use in patients with burn injuries. While it should be effective, efficacy and the potential for reduced adverse events need to be quantified. Current practice and guidelines, plead for better analgesia for patients with burn injuries.
NCT01225913
The purpose of this study is to evaluate the site and mechanisms responsible for expiratory airflow limitation in chronic, treated, non-smoking, stable asthmatics with moderate to severe persistent expiratory airflow obstruction. Treatment will include inhaled corticosteroids and long acting beta2agonists. The investigators are interested in determining whether the large and/or small airways are the predominant site of airflow limitation. The investigators are also interested in determining whether intrinsic small airways obstruction and/or loss of lung elastic recoil is responsible for expiratory airflow limitation. The investigators are also interested to evaluate the role of varying doses of inhaled corticosteroids to suppress large and small airway inflammation using exhaled nitric oxide as surrogate markers of inflammation. For comparison purposes, spirometry and measurements of exhaled nitric oxide will also be obtained if possible during a naturally occurring exacerbation of asthma.
