Filter by:The main aim of this multicentric 5-year follow-up study is to evaluate for the first time the long-term efficacy and safety (in terms of smoking-related serious diseases requiring hospitalization) of e-cigarette smoking, comparing its health effects with those of traditional cigarette smoking and mixed electronic and traditional cigarette smoking. The study will also permit to evaluate, over a 5-year follow-up, the self-reported quality of life, and the reported adverse events according to current and past smoking habit. Finally, the study will also explore the long-term adherence to e-cigarette smoking and its efficacy of e-cigarettes in reducing and/or quitting traditional cigarette smoking.
Our primary hypothesis is that Roflumilast (500 μcg, once daily) will significantly decrease surrogate markers of bone metabolism and early cardiovascular disease in individuals with moderate to severe airflow obstruction and a chronic bronchitis phenotype.
Loss of muscle protein is generally a central component of weight loss in Chronic Obstructive Pulmonary Disease (COPD) patients. Gains in muscle mass are difficult to achieve in COPD unless specific metabolic abnormalities are targeted. The investigators recently observed that alterations in protein metabolism are present in normal weight COPD patients. Elevated levels of protein synthesis and breakdown rates were found in this COPD group indicating that alterations are already present before muscle wasting occurs. The investigators recently observed that in order to enhance protein anabolism, manipulation of the composition of proteins and amino acids in nutrition is required in normal-weight COPD. Intake of casein protein resulted into significant protein anabolism in these patients. The anabolic response to casein protein was even higher than after whey protein intake. A substantial number of COPD patients, underweight as well as normal weight to obese, is characterized by an increased inflammatory response. This group failed to respond to nutritional therapy. Previous experimental research and clinical studies in cachectic conditions (mostly malignancy) indicate that polyunsaturated fatty acids (PUFA) are able to attenuate protein degradation by improving the anabolic response to feeding and by decreasing the acute phase response. Eicosapentaenoic acid (EPA) (in combination with docosahexaenoic acid (DHA)) has been shown to effectively inhibit weight loss in several disease states, however weight and muscle mass gain was not present or minimal. Until now, limited research has been done examining muscle protein metabolism and the response to EPA and DHA supplementation in patients with COPD. It is the investigator's hypothesis that supplementation of 2g/day EPA+DHA in COPD patients during 4 consecutive weeks will increase the muscle anabolic response to a high quality protein supplement as compared to a placebo, and supplementation of 3.5g/day EPA+DHA will increase the anabolic response even further. In the present study both the acute and chronic effects of EPA+DHA versus a placebo on muscle and whole body protein metabolism will be examined. The principal endpoint will be the extent of stimulation of net fractional muscle protein synthesis as this is the principal mechanism by which the effect of EPA+DHA on muscle anabolism can be measured. The endpoint will be assessed by isotope methodology which is thought to be the reference method.
Chronic Obstructive Pulmonary Disease (COPD) is a prevalent disease. In the investigators country, underdiagnosis has been estimated in around 80% of subjects. Early detection is done mainly in primary care but due to actual situation new alternatives have been proposed to decrease underdiagnosis. This present study promote by a multidisciplinary research team (respiratory medicine, primary care, nurse and pharmacist) raise the objective of evaluate the effect of a COPD case finding program guide by spirometry in community-pharmacies. From the results of a pilot-study conducted in 13 community-pharmacies in Barcelona, in which the investigators showed the feasibility of spirometry in community-pharmacies for the early detection of COPD, the investigators have design a second phase to evaluate the effect of this strategy. 100 Barcelona's community-pharmacies during 6 months will select high risk customers and will conduct a spirometry in agreement with the design protocol. 3600 spirometries is the establish objective. Participants hospitals will train pharmacist in spirometry and also control spirometry quality daily by a telematic pathway. Spirometry results will be evaluate in terms of effect and costs. The investigators will also evaluate the impact of this program in the health system by numbers of subjects diagnosed and follow up in primary care.
The purpose of this study is to assess the effects of a complex telemedicine intervention as a part of an integrated care program for patients with chronic obstructive pulmonary disease (COPD) discharged from the hospital after disease exacerbation. Will be evaluated whether the intervention produces benefits in terms of mortality, reduction in hospital readmissions and health-related quality of life. In addition, the trial evaluates the economical and organizational impact of the new service and examines its acceptability by patients and health professionals.
Phrase: IV Indication: dyspnea symptom of chronic obstructive pulmonary disease (COPD) Objective: to evaluate efficacy and safety of tulobuterol patch combined with Tiotropium bromide for relieving dyspnea symptom of COPD Design: a multi-centre randomized parallel blank control study Case number: test group 80, control group 80, totally 160 Site number:7 Study period: 2010.9 - 2011.8
Objective: To estimate the effectiveness of muscle training, the degree of dyspnea and aerobic capacity in patients over 50 with COPD, in a health care institution provider in Antioquia. Question: What is the effectiveness of muscle training, in the degree of dyspnea and aerobic capacity in COPD patients over 50 years, in a health service institution provider in the department of Antioquia? Hypothesis: Muscle training causes changes in the degree of dyspnea and aerobic capacity, other than the breathing exercises and relaxation Design: Randomized clinical trial with allocation and blinding of the autcomes assesor. Participants: COPD patients stage II and II, male and female, over 50 years old, who are attending to a community health service provider in the department of Antioquia. Intervention: A physiotherapeutic intervention using PNF technique was applied to the experimental physiotherapy group versus Yoga sessions applied to the other group. Twelve weeks protocol performing three sessions per week. Outcome measures: Dyspnea degree and aerobic capacity was measured using the MMRC scale and the six minute walking test respectively at the begining and the end of the study.
The Multi-Ethnic Study of Atherosclerosis (MESA) - Chronic Obstructive Pulmonary Disease (COPD) Study aims to characterize the pulmonary vascular changes and their biology in early COPD using imaging, gene expression profiling and peripheral cellular measures.
The aim of this prospective case-control study is to investigate the prevalence, severity and incidence of systemic consequences in newly detected patients with mild and moderate Chronic obstructive pulmonary disease (COPD). Special attention will be paid to skeletal muscle dysfunction and physical inactivity as these factors are, together with smoking, potentially modifiable.
The purpose of this study was to determine occurrence of ventilator associated pneumonia (VAP) in tracheostomized patients with COPD discharged in invasive mechanical ventilation (IMV) compared to patients with CPOPD discharged with tracheostomy but in non invasive mechanical ventilation (NIMV).
