Filter by:On day one, two groups of nine patients each will respectively recieve the tree daily meals (breakfast, Lunch and dinner) in a controled clinical setting. Group 1 will recieve a low-salycilate diet, and group 2 a high-salycilate diet. Two hours after each meal, urinary Leucotriene E4, FEV1, FVC, FEV1/FVC and total nasal resistance will be measured. On day 7, after clearance time, group 1 will recieve high-salycilate diet and group 2 low salycilate diet and the same measurements will be obtained.
Open and multicenter randomized clinical trial (1:1) comparing limited screening with extended screening with the performance of Positron emission tomography-computed tomography (PET-CT) scan in the search for neoplasms in patients with unprovoked venous thromboembolic disease at high risk of developing cancer at follow-up. Introduction: Cancer screening in patients with unprovoked venous thromboembolic disease (VTE) is controversial. In the last years, a score has been developed that selects patients at high risk of developing cancer during follow-up. Objective: To estimate the impact of an active cancer search strategy using 18-fluordesoxiglucose (FDG) PET-CT in unprovoked VTE with high-risk to develop cancer. Specific Objectives: 1) Number of neoplasms diagnosed in the screening process: 2) number of neoplasms diagnosed at an early stage, 3) impact on survival of the strategy; and 4) impact on the quality of life. Cancer will be considered from 30 days up to 12 months after the diagnosis of VTE. Scope: 20 Spanish hospitals. Design: Open-label, multicentre Randomized clinical trial (1: 1) comparing the performance of PET-CT versus limited screening for cancer. Population: Patients older than 18 years with unprovoked VTE at high risk of presenting cancer at follow-up (≥3 points in the score of Jara-Palomares et al., Chest 2017). Follow-up: 12 months after VTE. Sample: The sample size calculated is 650 patients, to obtain a power of 80%, with a level of significance of 5%, and taking into account a 10% loss of follow-up.
The Hamburg City Health Study (HCHS) is a large, prospective, long-term, population-based cohort study and a unique research platform and network to obtain substantial knowledge about several risk and prognostic factors in major chronic diseases.
Children represent 1.2% of the spa population in France. Spa treatments, including climatic stays, are mainly prescribed for children in the context of respiratory, otorhinolaryngology and dermatological conditions. The benefits after spa treatments are the improvement of the symptoms of the pathology, the quality of life and in particular the reduction of drug exposures. Few authors have recently investigated the impact of spa treatments on the health of children and society, while care has changed significantly in recent years. Moreover, no real-life study of a large sample of children seems to have been conducted in this area. The present study plan to conduct a pharmacoepidemiology study on medico-administrative databases of the "observational study" type, in real life.
Physical inactivity is a consequence of chronic diseases and on Chronic Obstructive Pulmonary Disease patients is an independent predictor of the risk of hospitalizations and early mortality. As physical inactivity is a modifiable risk factor with healthy lifestyle interventions, health professionals should clinically assess physical activity as a vital sign of patients' general physical condition. SmartReab study aims to characterize physical activity in daily life of 100 chronic respiratory patients at baseline when starting Pulmonary Rehabilitation, at discharge time of the program, at 6 months and 1 year follow-up. The Pulmonary Rehabilitation program will be individually tailored according to patients needs and goals settled within the Rehabilitation team and it will take place at Hospital Pulido Valente, from Centro Hospitalar Universitário Lisboa Norte, in Lisbon, Portugal. To access physical activity in daily life patients will participate in a telemonitoring study for 4 days using a smartphone and an oximeter and also answer to the International Physical Activity Questionnaire. SmartReab technology will provide data of physical activity intensity, heart rate and oxygen levels during awakening periods of daytime. To associate physical activity with other aspects related with health and the impact of Pulmonary Rehabilitation, patients will also take a 6 minute walk test and answer questionnaires related with self-perceived health status, impact of respiratory symptoms on quality of life, dyspnea impact on general mobility and on daily life situations, and also anxiety and depression feelings. The research hypothesis is that Pulmonary Rehabilitation will have a positive impact on physical activity in the short, medium and long terms.
This study will provide information regarding the sequential administration of two vaccines adjuvanted with AS01. The aim of this study is to understand immunogenicity and safety of NTHi-Mcat vaccine when administered sequentially after Shingrix vaccine and to compare to the immunogenicity of NTHi-Mcat vaccine administered alone. This study will also provide information regarding whether a specific time period is required between the administration of these two different vaccines containing the same adjuvant- AS01 components. The population of this study will include healthy smokers and ex-smokers of 50 to 80 years of age which will be used as a proxy for the COPD population.
Rhinitis, or inflammation of the nasal mucosa, can present with nasal obstruction, nasal discharge, itch or sneezing. If the sinusal mucosa is involved as well, it is called rhinosinusitis and facial pain or loss of smell is possible. Several causes are known, such as an underlying allergy ("allergic rhinitis", AR). If at least 2 symptoms are present for at least 12 weeks, it is called "chronic rhinosinusitis" (CRS). Up to 2/3 of the AR and CRS patients have symptoms upon exposure to triggers such as sudden temperature changes, smoke, fragrances… a phenomenon called "nasal hyperreactivity" (NHR). It is currently not clear why some patients suffer NHR while others do not. In this study, the investigators want to determine the prevalence and severity of nasal hyperreactivity in patients with chronic upper airway inflammation. To this end, patients and healthy controls will be asked to fill out a questionnaire inquiring presence and severity of nasal symptoms upon exposure to particular environmental triggers.
Background & Objective: Inspiratory muscle training (IMT) is known to improve strength and endurance of inspiratory muscles. However, clinical beneficial effects of IMT for patients with chronic respiratory disease remain inconclusive. The purposes of the study are to investigate in patients with chronic respiratory disease: (Year 1) main (diaphragm) and accessory inspiratory muscle (sternocleidomastoid muscle) activation pattern during various IMT loading using group-based trajectory modeling (GBTM); and (Year 2) effectiveness of individualized IMT program (based on results of Year 1) on clinical outcomes. Methods: (Year 1) Patients with chronic respiratory disease with inspiratory muscle weakness will be recruited for the study. Patients will perform 3 inspiratory loading tests (15%, 30%, and 50% of maximum inspiratory pressures) on 3 separate days with the sequence will be randomized. Surface electromyography (EMG) of diaphragm and sternocleidomastoid muscle will be used to use inspiratory muscle activation during various conditions. Other outcomes include maximum inspiratory pressure, and functional exercise capacity will be measured. Inspiratory muscle activation will be used for GBTM analysis. Patient will then be trained with individualized IMT program based on the GBTM analysis input form results of Year 1.
Study clinical characteristics and phenotypes of patients diagnosed with NSAID sensitivity in Thailand
Prevalence of aspirin-exacerbated respiratory disease (AERD) is 16% amongst patients suffering from chronic rhinosinusitis with nasal polyps (CRSwNP). The mechanisms underlying the observed dysregulation of pro and anti-inflammatory pathways in AERD are still not fully understood. To address this and also to identify potential factors characterizing the disease the investigators plan to prospectively collect blood samples, nasal secretions as well as nasal biopsies from allergic, non-allergic and AERD patients suffering from CRSwNP. Initially, polyps of aforementioned patients will be subjected to RNA sequencing analysis using microarray technology. Once distinct factors are identified in nasal polyp tissue, their presence will be assessed in nasal secretions and serum of the respective patients to investigate their potential role as biomarkers. Furthermore presence of these parameters will be confirmed in situ in biopsies by confocal microscopy. Knowledge about factors differently upregulated in polyp tissue from AERD may contribute to a better understanding of the underlying mechanism of the disease.
