Filter by:Respiration failure type 2 is loss of the lungs ability to take up oxygen (O2) and get rid of carbon dioxide (CO2). The diagnosis is based on blood gas measurement of pressures of O2 and CO2. Patients with COPD is often seen to have co-morbidity with cardiac diseases. Chronic systemic inflammation is seen in both COPD and cardiac diseases. The investigators will investigate the sleep quality, CO2-retention, O2-saturation, cardiac arrythmias and markers of inflammation in 120 patients with COPD in different stages of the disease. Our hypotheses are: - that the first signs of respiration failure type 2 is seen during sleep with alteration of sleep patterns and greater and more long-lasting retention of CO2 in the blood compared to those with a normal lung function - that the use of alcohol, zopiclone or supplementary oxygen will make these differences even greater - that cardiac arrythmias correlates with hypoxemia - that cardiac arrythmias and respiration failure correlates with degree of inflammation
The purpose of this study is to evaluate the clinical outcome and safety of flutter mucus clearance devices in elders of gerocomium.
Asthma and chronic obstructive pulmonary disease (COPD) are diseases that affect a person's ability to breathe normally. People who do not receive enough vitamin D may have a higher risk of developing asthma or COPD. This study will examine previously collected blood samples of participants in three studies to determine whether people with low vitamin D levels have an increased risk of severe asthma or COPD.
During general anesthesia, airway closure and the formation of atelectasis impair oxygenation. During one-lung ventilation, large tidal volumes are used to resume atelectasis with a risk of regional over distension and Ventilator-Induced Lung Injury (VILI). The reduction in TV should reduce the occurrence of VILI but lead to a consistent alveolar derecruitment. This harmful effect may be counteracted by PEP. We, therefore, study the impact on oxygenation, of increasing PEP during OLV, in order to maintain alveolar recruitment when TV is reduced.
This study will examine bacteria and toxins in the mouth, lung and digestive system that may be the cause of various diseases or symptoms. H. pylori is a bacterium that produces various toxins that may contribute to lung problems. This study will examine specimens collected from the mouth, teeth, lung, digestive tract and blood to measure H. pylori and its toxins and their effects on cells. People 18 years of age and older with or without gastrointestinal disease may be eligible for this study. These include people without a history of lung disease as well as patients with any of the following: lymphangioleiomyomatosis, asthma, sarcoidosis, other chronic or genetic lung disease (e.g., chronic obstructive pulmonary disease, cystic fibrosis or eosinophilic granuloma). Participants may undergo the following tests: - Blood and urine tests, chest x-ray. - Measurement of arterial blood gases: A small needle is placed in an artery in the forearm to collect arterial blood. - Lung function tests: Subjects breathe deeply and occasionally hold their breath. They may also receive a medication that expands the airways. - Fiberoptic bronchoscopy with lavage and bronchial brushing: The subject's mouth and throat are numbed with lidocaine; a sedative may be given for comfort. A thin flexible tube called a bronchoscope is advanced through the nose or mouth into the lung airways to examine the airways. Saline (salt water) is then injected through the bronchoscope into the air passage and then removed by gentle suction. Next, a small brush is passed through the bronchoscope and an area of the airway is brushed to collect some cells for examination. - Mouth rinsing or teeth brushing to collect cells. - Endoscopy: A small needle and catheter (thin plastic tube) are placed into an arm vein to administer fluids and medications through the vein. A sedative may be given. The throat is numbed with lidocaine and a thin flexible tube called an endoscope is inserted through the mouth and down the esophagus into the stomach and upper part of the small intestine to examine those areas.
Incidence of cancer in 75+ years old is 16,500 new cases per year, more than fifty percent of people with cancerThey are very few therapeutic trials dedicated. Oncologists hesitate to treat them because they are either afraid of inducing toxicity or of breaking down quality of life. Consequently, we decided to launch a protocol with both oncologists and geriatricians which principal aim is to find out if geriatric assessment data can help to better predict for chemotherapy toxicity, loss of autonomy and survival. We plan to accrue 360 patients diagnosed for cancer, including digestive, pulmonary, prostate, lymphoma, bladder, ovary cancer for whom first-line chemotherapy is planned. Patients are initially classified according to usual methods of medical oncology practice into three groups: patients who can receive standard treatment, reduced standard treatment or treatment adapted to the frail condition. Around Aquitaine, , we organised seven teams composed of one geriatrician and one nurse. Two kind of teams were activated: one which cover ten treatment sites in Bordeaux area and six sedentary teams which worked half a day a week in designated hospitals . Geriatric evaluation included test of cognitive functions (MMS), nutritional status (MNA), co-morbidity (CIRS-G), mobility (Get up and Go), activities (ADL;IADL), quality of life (QLQ-C30), depression (GDS-15) and Lachs-Balducci screening. Patients have four geriatric evaluations : before treatment, day 1 cycle 2, day 1 cycle 4, day 1 cycle 7 and/or end of chemotherapy. Since September 2002, 177 patients have been included, 112 have finished: 47.3% have received four evaluations, 16.1% died before the end of protocol, 14.3% stopped because they were in progression and changed their treatment, 11.6% met administrative problem that didn't allow all evaluations, 7.1% declined after inclusion and 3.6% finished their treatment before. The following results have been obtained: before treatment, 73% of these patients were at risk of undernutrition (MNA< 23.5), about 1/3 had one or more inability or a risk of falls (38% IADL<6, 29% get up and go>20seconds, 27% ADL>1, 34% PS<1), 28% of them had altered cognitive functions (MMS<24), 29% were depressive (GDS-15>6), 25% thought they had poor quality of life (QLQ-C30<4). Protocol will be closed in September 2005.
The purpose of this study was to compare the effect of exercise treatment combined with breathing retraining (a computerized feedback program), with exercise treatment combined with heliox (a helium and oxygen combination), with exercise only in patients with moderate to severe chronic obstructive pulmonary disease. This was an 8-week intervention study.
The purpose of this study is to evaluate a multifaceted intervention to improve the quality of end-of-life communication between patients with COPD and their primary care providers using information about patients preferences for end of life care and how to communicate and use this information to activate patients, family members, and healthcare providers.
The purpose of this project is to do cross species comparisons of the metabolism and toxicity of a number of toxicants which require metabolism for toxicity. All of the toxicants in question are encountered by humans in the workplace, through lifestyle choices (cigarette smoking) and as a result of environmental contamination. The high incidence of pulmonary diseases in the human population means that it will be difficult if not impossible to determine whether humans are at risk from exposure to these chemicals without solid mechanistic data. Recent rodent bioassays suggest that these compounds have oncogenic potential further supporting the need to test the potential for injury in primates. As part of this testing, we intend to establish in vitro methods for assessing critical steps in the metabolism of these agents and their interaction with cellular macromolecules. Once this is done, similar studies can be conducted in Rhesus or in human lung tissue that is available because it cannot be used for transplant purposes.
This study was developed in order for the professional-staff at the Pulmonary-Critical Care Medical Branch (PCCMB) of the National Heart, Lung, and Blood Institute to maintain their skills and increase their understanding of lung diseases. The study will permit PCCMB staff members to evaluate and treat patients with lung disease who do not meet the criteria for other research studies.
