Active clinical trials for "Respiration Disorders"

This study aims to validate dried blood spots (DBS) for SARS-CoV-2 (Severe Acute Respiratory Syndrome 2) antibody detection in elderly individuals.

Aim: The aim of the clinical trial is to study the accuracy of the TensorTip device compared with registered (FDA-approved) invasive and non-invasive devices. Hypothesis: Human physiological biomarkers may be measured from the color distribution of the internal or external (skin) tissue. The technology of the TensorTip finger-mounted device is based on the color distribution of the peripheral blood tissue, which enables the measurement of certain biomarkers and vital signs under consideration.

Many "Survivors" in the World Trade Center (WTC) clinical program have a clinical syndrome characterized by chronic obstruction in small airways and persistence of lower respiratory symptoms despite therapy. This study will test the hypothesis that persistent symptoms in WTC "Survivors" are associated with abnormal small airways whose dysfunction is amplified during exercise and is associated with biologic evidence of inflammation and remodeling. The results from this study will have important treatment implications for our WTC population with potential applicability to larger populations with either inhalational lung injury and/or airway diseases such as asthma and chronic obstructive pulmonary disease.

The purpose of this study is to evaluate the accuracy of RespiLife diagnostic technology for detection of respiratory rate and oxygen saturation in human subjects. This includes evaluation of Bioresp's RespiLife and its accuracy for measurement of respiratory rate and oxygen saturation.

A fast track recovery program (thoracic epidural anesthesia, carbohydrate drink preoperative, early removal of chest tubes) is evaluated compared to conventional perioperative treatment (patient controlled analgesia, no carbohydrate drink preoperative) in patients with FEV1 < 70% of expected value or < 1.5L who undergo resections of the lung.

The caesarean section rate is rising globally. About 10% of the newborns are submitted to a neonatal department after planned caesarean section, primarily with respiratory disorders. More children are submitted if caesarean is performed earlier in pregnancy. Study hypothesis: More newborns are admitted after planned caesarean at 38 weeks and 3 days of gestation than after 39 weeks and 3 days of gestation. Aim of study: To compare elective caesarean section performed at 38 weeks and 3 days of gestation with 39 weeks and 3 days of gestation. According to this timing to determine the proportion of newborns admitted within 48 hours after birth.

Randomized controled trial to compare oxygen desaturation during fiberoptic bronchoscopy using oxygen administered with nasal prongs and high flow nasal cannula. Drops in oxygen saturation are frequent during bronchoscopy and limit the procedure compromising patient security. The investigator's aim is to contribute to select better way of oxygen administration which could prevent desaturations during bronchoscopy in children.

Aspirin Exacerbated Respiratory Disease (AERD) is a relatively homogeneous disease characterized by adult-onset severe asthma, development of non-cancerous growths in the nasal canal (i.e. nasal polyps) and aspirin allergy. The cause of AERD is unknown, although likely results from environmental insults in combination with genetic susceptibility. AERD disease homogeneity increases the possibility of discovering narrowly-defined genetic contributors, and makes it an ideal population to study the genetic and epigenetic changes that cause asthma. Researchers recently discovered that gene expression of epithelial growth and repair (EGR) genes are substantially decreased in bronchial airway epithelial cells of severe asthmatics compared to less severe asthmatics and healthy controls. This new finding indicates that epithelial integrity and related processes may be of primary importance to the development of severe asthma, and potentially the severe asthma subtype, AERD. This finding was later supported in a subsequent lab model, which showed that blocking a central epithelial repair and differentiation gene, human epidermal growth factor receptor 2 (ERBB2), decreased healing time of bronchial epithelial cells after injury. Thus, the objective of the proposed study is to determine whether EGR gene are also down-regulated in AERD, a homogeneous severe asthma subtype. As an extension, the researchers will also determine whether genetic mutations and/or epigenetic changes relate to and potentially explain this down-regulation of EGR genes. Specifically, the researchers plan to obtain gene expression of freshly brushed nasal airway epithelial cells of 140 AERD patients, 70 non-aspirin sensitive asthma patients, and 35 healthy controls, noting that nasal epithelial gene expression has recently been shown to mirror lung epithelial changes in asthmatic airways. Swabbing the nasal canal for epithelial cells allows to evaluate airway epithelial cell gene expression non-invasively. Our experimental design contrasts AERD gene expression profiles against healthy controls, and determines whether EGR genes are depressed in AERD relative to health controls. As a corollary, the researchers look to discover an AERD-specific gene expression profile which may one-day aid in diagnosis and expand current knowledge of disease mechanisms. As an extension, the researchers will correlate gene expression changes, specifically any finding of down-regulated EGR genes, with methylation changes (i.e. epigenetic changes) and genetic mutations.

Subjects will use the Gabi system on a daily basis for 3 months, each time the subject is resting or asleep. The Gabi system will recording the SpO2, pulse rate, respiratory rate and movements of the subject. The objective of this study is to perform a first assessment of the range of most potentially clinically relevant indications for use of the Gabi system for children < 6 years old with underlying medical conditions. This is performed by asking HCPs to review the data measured by the Gabi system after taking a medical decision independently from the Gabi data and to assess the potential clinical utility of the Gabi system. The usability of the system will also be assessed throughout questionnaires filled out by the HCPs and by the caregivers. *During this study, the data collected by the Gabi system are not intended to be used by caregivers or HCPs to take any (medical) decisions.

Introduction: The pregnancy brings about physiological and hormonal modifications which cause sleep disorder. The sleeplessness, snoring and a bad sleepquality are frequent during the pregnancy. Also a limited breathing airflow happens very often during the pregnancy. The limited airflow causes micro-awakenings that enter in the frame of the high resistances airways syndrome. To our knowledge there is no study about the outcome of micro-awakenings at pregnant women. Objectives: To compare the prevalence of the high resistances airways syndrome (RERA) in pregnant woman with or without gestational diabetes Methods : It is a monocentrical prospective study at pregnant women after the 30th amenorrhea week who consul the gynecologie and obstetrics department of the CHU NORD in Marseille. We are going to compare the breathing disorder during sleep of a control group with a group of women with gestational diabetes. A polysomnograph will be run at the included patients' home. Expected results : The physiological and hormonal modifications during the pregnancy could favor nocturnal sleep events (snoring, SAHOS and RERA) and its complications as gravidic HPN And gestational diabetes cause maternal and fœtal and morbidity and mortality. We put the hypothesis that limited airflow in association with micro-awakenings in the RERA have a negative impact on the glucose metabolism and favor the gestational diabetes.
