Active clinical trials for "Respiration Disorders"

Extubation stay at high risk of reintubation even scheduled and in the best condition of hematosis. Re-intubation's rate in main studies in chronic obstructive diseases reach to 20% and it is associated to a higher mortality, higher pneumonia under mechanic ventilation, and higher duration of hospitalization especially in intensive care units. Place of NIV in this situation is still on evaluation. A recent meta-analysis demonstrates that use of NIV in post-extubation in COPD seems to decrease re-intubation rate. HFO, thanks to its properties (oxygen, humidification and heat with high flow) could be useful in this population in ventilatory weaning. Compared to oxygen conventional therapy with high-concentration mask, HFO seems to be as efficient and better tolerated. A recent study shows that HFO is non-inferior to NVI in post-extubation in patient with high risk of re-intubation. Furthermore, oxygenation in post-extubation should be optimized to avoid hypoxemia and hypercapnia in this patient at risk of hypoventilation. Place of AFOT could improve hematosis by providing adapted flow of oxygen to each patient. The investigator choose the hypothesis for this study that HFO is as effective and tolerated in post-extubation than NIV with AFOT.

This study investigates the effect of two different techniques, stretching of the diaphragm and cervical level impulse technique C3-C4, in the possible spirometric changes, vital capacity (CV), maximum expiratory flow (PEF) and maximum expiratory volume (FEV). in relation to the secondary variables (age, physical activity, BMI, sex). the subjects of the study were informed and clarified doubts about it and its subsequent reading and signing of informed consent. The subjects were randomly selected to determine which intervention group they would belong to (G1: intervention group of the diaphragm muscle stretch technique, G2: intervention group of the cervical rotation rotation impulse technique C3- C4, G3: Combined technique G1 and G2, G4: control group.The evaluation technique is spirometry.The intervention protocol is as follows, first the pre-intervention spirometry is performed, then the corresponding technique (according to intervention group), then the post-intervention spirometry, the intervention technique and at 5 minutes, the intervention technique is performed.

This is a phase 4, randomized, double-blind, multicenter clinical trial to evaluate the efficacy and safety of YMC026 in respiratory disease patients with cough and sputum as the main symptoms

Lung cancer rates are higher in Yorkshire than the rest of the UK, and this is due to higher rates of smoking. Deaths from lung cancer can be reduced using regular lung scans (screening) and by helping people stop smoking. As well as detecting cancers, scans can also show evidence of damage to lungs (emphysema) and heart arteries (calcification). This study will test whether people can be encouraged to quit smoking by giving them pictures from their own scans showing possible lung and heart damage, along with information about how stopping smoking reduces their risk of cancer and heart attacks.

To minimize the negative effects of exposure to silica, iron chips, and coke on the respiratory health of workers in the Ferro alloy factory, so it is important to assess and diagnose their health-related effects. Early reporting, diagnosis, and intervention can limit the severity of health hazards, improve health services. To our knowledge, no local previous studies were done in this area. All over the world there is no sufficient information relating to this industry and its health hazards.

The aim of our study is to compare the effectiveness of the supervized pulmonary telerehabilitation program and the cognitive telerehabilitation method, which includes pulmonary telerehabilitation methods, in patients with severe stage COPD who have difficulty exercising heavily. The effects of pulmonary and cognitive rehabilitation on dyspnea, muscle strength, functional capacity, quality of life, anxiety and depression levels in this patient group will be examined. The number of studies in the literature in which the pulmonary rehabilitation program was applied as telerehabilitation is insufficient. Considering that this patient group is not motivated and has difficulty in exercising, motor imagery and movement observation methods from cognitive rehabilitation methods may be alternative methods for these patients. Although these methods have been very popular in recent years in terms of researching and demonstrating their effectiveness in various patient groups in the literature, no study has been found in which the effects of these methods have been applied in pulmonary disease groups. This study aims to contribute to the serious gap in the literature on the application of pulmonary telerehabilitation and its effectiveness, and to be an original study by investigating the effectiveness of motor imagery and action observation, which are popular rehabilitation methods of recent years, in COPD patients in the pulmonary disease group for the first time.

Rationale: The most common approach to weaning infants and children is gradual reduction of ventilatory support ("traditional approach"). Alternatively, another approach to weaning is attempted with alternating periods of complete ventilatory support and graded spontaneous breathing with assistance ("sprinting approach"). Both approaches are used randomly in our unit: the decision to use which approach is dependent upon the preferences of the attending physician as described in many observational single center studies. To date, there is no data comparing the safety and efficacy of the "sprinting" approach with more traditional approaches of weaning in children. Hence, numerous issues remain unanswered, including the work-of-breathing during each approach. For this research proposal, we want to measure the work-of-breathing daily, using the traditional approach (the area under the oesophageal pressure - volume curve) and study its correlation with clinical parameters and EMG activity of the diaphragm and intercostal muscles from the moment that the patient is weaned off the ventilator. Objective: The primary objective for this study is to compare for each patient of the work-of-breathing during the "sprinting"approach and the "traditional approach.The secondary objectives for this study are to compare the oesophageal pressure rate and (PRP) and pressure time product (PTP), the PaO2/FiO2 ratio, global and regional distribution of tidal volume measured using electrical impedance tomography (EIT), phase distribution of the respiratory inductive plethysmography (RIP) signal and the EMG activity of the diaphragm and intercostal muscles between the "sprinting"and the "traditional" approach.. Study design: This is a prospective exploratory study with invasive measurements in a 20 bed tertiary paediatric intensive care facility at the Beatrix Children's Hospital/University Medical Centre Groningen. Study population: All mechanically ventilated children aged 0 to 5 years with or without lung pathology admitted to the paediatric intensive care unit are eligible for inclusion. Inclusion criteria include mechanical ventilation for at least 48 hours, weight ≥ 3 kg, sufficient respiratory drive present, deemed eligible for weaning by the attending physician, and stable haemodynamics (defined by the absence of need for increase in vaso-active drugs and/or fluid challenges at least 6 hours prior to enrolment). Exclusion criteria include mechanical ventilation less than 48 hours, not eligible for weaning (usually when there are unstable ventilator settings, defined by the need for increase of inspiratory pressures or positive end-expiratory pressure, and a FiO2 > 0.6 within 6 hours prior to enrolment), unstable haemodynamics (defined by the need for increase in vaso-ative drugs and/or fluid challenges within 6 hours prior to enrolment), leakage around the endotracheal tube > 5%, admitted to the neonatal intensive care unit, preterm birth with gestational age corrected for post-conceptional age less than 40 weeks, congenital or acquired neuromuscular disorders, congenital or acquired central nervous system disorders with depressed respiratory drive, congenital or acquired damage to the phrenic nerve, congenital or acquired paralysis of the diaphragm, use of neuromuscular blockade prior to enrolment, uncorrected congenital heart disorder, and chronic lung disease. Main study parameters/endpoints: The main study parameter is the level and time course of the patient's work-of-breathing mathematically calculated by the area under the pressure-volume curve Secondary study parameters include the level and time course of the PRP and PTP, level and time course of oxygenation (PaO2/FiO2 ratio), global and regional distribution of tidal volume, phase distribution, EMG activity of the diaphragm and intercostal muscles, heart rate, respiratory rate.. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: There are a priori no specific benefits for the patients who participate in the study.

The objective of the study is to confirm the safety and efficacy in patients utilizing the aura6000 System for the treatment of Obstructive Sleep Apnea (OSA).

Rationale: COPD is increasing in prevalence among people living with HIV/AIDS (PLWHA) as widespread use of ART has increased longevity in this population. In rural Ugandan ART clinics, we report COPD prevalence of 6.22%. Currently, it's not fully known what drives chronic lung inflammation in PLWHA population despite being virologically suppressed on ART. There is need to explore factors driving chronic airway inflammation among PLWHA. Airway microbiome has been implicated in the pathogenesis of COPD. Preliminary analysis from our study revealed that, specific microbes were significantly enriched in PLWHA with COPD with more lung bacteria impacted by HIV than COPD. These findings suggest that HIV-associated changes in unique airway microbial genera may be driving COPD among PLWHA in our cohort. Currently, we don't know how such genera drive chronic airway inflammation. Study objectives: In this study, we will: (1) establish a relationship between airway microbiome and Th17/Treg cellular phenotypes among HIV-infected individuals with COPD; (2) investigate bacterial-mediated Th17 upregulation of pro-inflammatory and pro-fibrotic genes among HIV individuals with COPD and (3) explore the role of bacterial outer membrane vesicles (OMVs) in mediating microbiome driven Th17 immune responses among HIV individuals. Methods: We will conduct a 2-year case-controlled study, leveraging on the established lung microbiome cohort in rural Nakaseke district of Uganda. We will recruit 80 HIV-infected individuals ≥35 years attending the ART clinic at Nakaseke General Hospital screened for COPD as well as 80 HIV-negative controls ≥35 years attending the pulmonary clinic at Nakaseke General Hospital screened for COPD. In both cases and controls, we will consider 40 stable COPD participants and 40 participants with no COPD. Recruited participants will undergo sputum induction protocol at our newly established negative pressure sputum induction facility at Nakaseke General Hospital following established standard operating procedures. Using induced sputum samples, we will (i) perform 16S sequencing and metagenomics analysis to determine airway bacterial communities, (ii) RNA sequencing and analysis to determine gene expression profiles, mass flow cytometry and analysis to profile immune cells in induced sputum of study participants as well as (iv) ELISA tests to compare OMV levels between participants.
