Active clinical trials for "Respiration Disorders"

This study will provide information regarding the sequential administration of two vaccines adjuvanted with AS01. The aim of this study is to understand immunogenicity and safety of NTHi-Mcat vaccine when administered sequentially after Shingrix vaccine and to compare to the immunogenicity of NTHi-Mcat vaccine administered alone. This study will also provide information regarding whether a specific time period is required between the administration of these two different vaccines containing the same adjuvant- AS01 components. The population of this study will include healthy smokers and ex-smokers of 50 to 80 years of age which will be used as a proxy for the COPD population.

Physical inactivity is a consequence of chronic diseases and on Chronic Obstructive Pulmonary Disease patients is an independent predictor of the risk of hospitalizations and early mortality. As physical inactivity is a modifiable risk factor with healthy lifestyle interventions, health professionals should clinically assess physical activity as a vital sign of patients' general physical condition. SmartReab study aims to characterize physical activity in daily life of 100 chronic respiratory patients at baseline when starting Pulmonary Rehabilitation, at discharge time of the program, at 6 months and 1 year follow-up. The Pulmonary Rehabilitation program will be individually tailored according to patients needs and goals settled within the Rehabilitation team and it will take place at Hospital Pulido Valente, from Centro Hospitalar Universitário Lisboa Norte, in Lisbon, Portugal. To access physical activity in daily life patients will participate in a telemonitoring study for 4 days using a smartphone and an oximeter and also answer to the International Physical Activity Questionnaire. SmartReab technology will provide data of physical activity intensity, heart rate and oxygen levels during awakening periods of daytime. To associate physical activity with other aspects related with health and the impact of Pulmonary Rehabilitation, patients will also take a 6 minute walk test and answer questionnaires related with self-perceived health status, impact of respiratory symptoms on quality of life, dyspnea impact on general mobility and on daily life situations, and also anxiety and depression feelings. The research hypothesis is that Pulmonary Rehabilitation will have a positive impact on physical activity in the short, medium and long terms.

This trial will evaluate the effect of acetazolamide (375 mg per day) vs. placebo on lung water content by ultrasound at acute altitude exposure in patients with Chronic Obstructive Pulmonary Disease (COPD).

It is known that the pretreatment with exogenous interferon blocks SARS-CoV-2 infection, but intervention is much more effective if administered prior to infection. In this study the primary aim is to investigate 28-day regime of nasal interferon gama use in healthy participants for COVID-19 and other respiratory infections prevention.

Vibration Response Imaging (VRI) is novel technology which records breath sounds via pizo-electric sensors and produces a digital image using a computer algorithm. It is radiation free and is portable to the patient's bedside. Data exists to show that the recordings from normal individuals differs from those who have pulmonary pathology. There is also evidence that recordings have high levels of inter and intra-observer reliability. However, data on specific VRI patterns for specific pathology is still needed before this can be used as a diagnostic tool. We aim to perform an open label feasibility trial on inpatient and outpatient pulmonary patients. Bedside clinical examination and chest auscultation will be used as the reference gold standard. Other diagnostic modalities that have been used as part of the patient's usual standard of care will also be used for comparison. Specifically breath sound progression, the maximal sound energy shape/distribution and the presence of artifactual sounds will be used to search for patterns that may be used for diagnosis. Sensitivity and specificity will be calculated for each disease (eg. asthma, emphysema, bronchiectasis, pneumonia, effusion, pneumothorax, etc)

This is a single-center open-label study to evaluate antimicrobial photodynamic therapy (aPDT) for upper airway decolonization in patients presenting with SARS-CoV-2 positive antigen test with mild or no symptoms of COVID-19.

A comparative study to test the efficacy of a novel device - the MiniBoxPFT, in measuring TLC (total lung capacity) compared to TLC measured by standard body plethysmography using the ZAN 500. The study will be conducted as a prospective two-arm, open, randomized comparative study.

To investigate the efficacy and safety of using the novel Tyto device for remote physical examination by co-investigators as compared to a standard medical physical examination by physicians.

The purpose of this study is to test two different vaccine schedules to be used for administering the investigational NTHi Mcat vaccine that will be targeting patients with chronic obstructive pulmonary disease (COPD) to prevent acute exacerbations. An acute exacerbation is when the breathlessness in COPD patients will get even worse than it normally already is, sometimes to the point where oxygen therapy is required. In previous studies, study participants have received two doses of the vaccine according to a 0, 2 month vaccination schedule, in addition to standard care. The current study will find out if a third dose of the study vaccine against NTHi/Mcat is safe and working well. The study will also investigate if the third dose of vaccine works best when given after 6 months or after 12 months.

The purpose of this study is to test if the vaccine is working well in COPD patients aged 40 to 80 years old to reduce episodes of worsening symptoms ("exacerbations") and to gather further information on safety and immune response. In the current study, COPD patients with a history of acute exacerbations will receive 2 doses of the investigational vaccine or placebo intramuscularly according to a 0, 2 month vaccination schedule, in addition to standard care. The effect of vaccination against two pathogens known to cause exacerbations (Non-typeable Haemophilus influenza [NTHi] and Moraxella catarrhalis [Mcat]) will be evaluated at pre-defined timepoints (scheduled study visits). In addition to the scheduled study visits, additional study visit(s) and/ or phone contact(s) will take place for each acute exacerbation of COPD occurring from first vaccination up to study conclusion.
