Filter by:All measurements are performed on two consecutive days at the beginning of a pulmonary rehabilitation program in a randomized cross-over study design. On the first day, each patient is randomly assigned to perform either the 2 minute walk test or the 6 Minute walk test. On the second day each patient performs the test that was not performed on the first day. All walk tests are performed by the same investigator on the same track and time of day, following the 2002 guidelines of the American Thoracic Society. Patients wear a mobile pulse oximeter that continuously records heart rate and oxygen saturation during testing. Baseline values of oxygen saturation, heart rate and ratings of perceived exertion on the modified Borg scale (0 to 10) for dyspnea and leg fatigue are recorded at rest after 10 minutes of sitting.
The purpose of this study is to measure the effectiveness and safety of TD 4208, an investigational drug being developed to treat people with moderate to very severe COPD, compared to placebo, a treatment without activity.
The World Health Organisation predicts that lung disease will be the World's third largest killer in the future. This research project is looking to see whether the concept of a "home hospital" using the latest gadgets and iPad technology, can help patients stay well and out of hospital. Portsmouth Hospitals Trust is collaborating with a Company based in the United Kingdom (UK) who has developed a test to predict when people with lung diseases, such as; asthma, COPD and bronchiectasis, who regularly have chest infections, are about to become poorly with another infection - a form of early warning system. The investigators hope that the test will eventually be able to be used by the patient at home daily, to help self-manage their condition. The test measures whether bacteria are present, in sputum, and in what quantity. This information can be used by the patient's healthcare team to consider providing treatment earlier, thus controlling the infection sooner and reducing the patient's symptoms so that patients can stay at home rather than being regularly admitted to hospital. Part of this "early warning system" that has been developed by the UK Company includes the daily measurement of a number of indicators of health. These are usually only measured in hospital or by a General Practitioner, but new devices have been made that are simple enough for everyone to use at home. The investigators will include 30 participants, with non-Cystic Fibrosis (CF) chronic respiratory conditions who will be asked to take daily measurements of their blood pressure, temperature, weight and how well their heart and lungs are working with easy-to-use devices. They will also measure their physically activity with an activity tracker and report their wellness and whether they have taken medication daily. Participants will also be asked to collect a sample of sputum and urine each morning. Taking the samples and measurements should only take between 5-15 minutes each day to carry out. The sputum and urine will be tested at the hospital and will be recorded and analysed, so that the researchers can learn what happens well before a person with these conditions falls sick and needs hospitalisation.
The aim of this study is to evaluate the incidence and status of urgent medical conditions. After defining the urgent situations, the investigators will evaluate the adequacy of the standard medical kits and trainings.
Breathlessness, the sensation of breathing discomfort, is a major problem in people with chronic obstructive pulmonary disease (COPD). Breathlessness that persists despite optimal management of the underlying disease(s) is said to be refractory. Preliminary evidence suggests that a small, regular dose of morphine helps to reduce safely the sensation of breathlessness. However, this research on morphine for breathlessness has not defined the best way to adjust the dose of the medication, or refined which people are most likely to have benefit, no response or side effects. This is a randomized, double-blind phase III trial in people with COPD and significant refractory breathlessness, which will explore several important questions: - Are regular, low dose opioids (morphine) at four possible doses over 3 weeks more effective than placebo medication (containing no active ingredient) at improving breathlessness? - Does the medication have any effect on daily activity, breathlessness, and quality of life? - What are the common side effects of this intervention? - Does the benefit from the drug outweigh the side effects it produces? - Are there specific characteristics of people who are more likely to receive benefit from sustained release morphine? Participants will be allocated to receive three weeks of morphine sulfate (and laxative, docusate with senna), or placebo (and placebo laxative). The dose of morphine may be increased each week for weeks two and three. All medicines will appear the same (blinded) and neither the doctor nor the participant will know which medication the participant is receiving. Participants will have a medical interview, physical examination to collect some general health information, and baseline measurements including; daily activity, symptoms, and quality of life. A small amount of blood may be required to check eligibility. Further blood samples may be taken at week 1 and 3 to enable testing on how individuals respond to opioids, further consent will be obtained for these samples. Data on benefits, side effects, and medical care will be collected during comprehensive weekly visits. Participants will also fill out a simple diary twice daily for weeks one to three of the study, and for one day each week during an optional 3 month extension stage. The outcome of this study may enable better management of symptoms and activity in people COPD with medicines that are shown to be effective and safe.
Randomized, placebo controlled trial evaluating efficacy of dexamethasone in preventing sleep related breathing disturbances in lowlanders with chronic obstructive lung disease travelling from 700 m to 3200 m.
Randomized, placebo controlled trial evaluating efficacy of dexamethasone in preventing acute mountain sickness in lowlanders with chronic obstructive lung disease travelling from 700 m to 3200 m.
There is preliminary evidence that a dynamic T2 Preparations Puls sequence by cardiac magnet resonance imaging can differentiate between oxygenated and deoxygenated blood. In adult patients with inborn heart defects this has not yet been researched. Therefore,patients with ventriculoperitoneal shunt, septal and atrio-septal shunt should be examined. Also, patients with chronic obstructive pulmonary disease should be examined. The aim of this study is the validation of a novel magnet resonance sequence in terms of a distinction of oxygenated blood to deoxygenated blood in comparison to invasive method of measuring cardiac catheterization.
To evaluate the efficacy, safety and tolerability of multiple doses of QBW251 vs placebo administered orally, on airway function, lung volume, and quality of life in patients with chronic obstructive pulmonary disease (COPD)
Metered Dose Inhaler (MDI) and Dry Powdered Inhaler (DPI) are the two most common devices used to deliver medicine in conditions such as asthma and chronic obstructive pulmonary disease. It is well-known that most patients do not use correct technique when using a metered dose inhaler. This leads to poor control of their disease. This study is being done so the investigators can record the patient using the metered dose inhaler before and after a short teaching session. This information will be fed into an invitro system (device) to allow the researchers to study the effect of error on drug delivery. The device being used is the Rice R3 electronic flowmeter.
