Filter by: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.
This is a single and multiple dose, single centre, open-label, one-way, pharmacokinetics, safety and tolerability clinical trial of Phase I to be performed in Chinese healthy male and female volunteers. Twenty-four (24) healthy male and female Chinese volunteers will be included in the study. Drop-out subjects will not be replaced. The study has been designed in agreement with the Chinese Technical Guideline on Clinical Pharmacokinetic Research of Chemical Drugs, 18 March 2005 and the European Guideline on the Investigation of Bioequivalence. No randomisation will take place in this study. All the participant will receive the same treatment with the investigational medicinal product (IMP), i.e. NAC, 300 mg/ 3 mL solution for injection.
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.
Background The medical helpline 1813 in Copenhagen, Denmark handles telephone calls regarding non-life-threatening medical emergencies. Next to 200,000 calls/year concern children and afterwards about 30% are referred to a pediatric urgent care center. However, most of these children have very mild symptoms, which do neither require treatment nor any tests, but merely parental medical guidance. Initial assessment; triage, of children on the telephone is difficult, especially when the operator does not know the child or the parents, and when it is difficult to describe the symptoms in medical terms. This may result in both too many not-so-sick children getting unnecessarily referred to hospitals, and perhaps also too few more severely sick children sent to the hospital. Purpose This project will study if triage of children by videocalls (video triage) provide greater security for parents and health care personnel in the decision that more children can stay at home after medical guidance, thus causing at least 10% fewer visits to a pediatric urgent care center. Furthermore, the investigators will study if video triage identifies more children with the need of urgent admission to a Department of Pediatrics. Method Children aged 6 months to 5 years with symptoms from the respiratory tract will be triaged by either video or telephone by an operator every other day, in order to compare the results between these two similar groups. In cases of video triage, the parent will receive a text message to their smartphone with a video link. The safety of video triage will be assessed by reviewing the hospital case reports of all patients for contact within the 48 hours after the 1813 call. Perspectives Video assessment at call centers may "give eyes to the operators" and revolutionize telephone triage. The study may result in fewer children referred to hospitals, more appropriate use of resources and better experiences for the families.
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.
This is a phase 3, multicenter, randomized, rater- and patient-blind, placebo- and active-controlled, 3-arm parallel group clinical trial. Patients will be randomized to N-acetylcysteine (NAC) or ambroxol or placebo in a 1:1:1 ratio. A total of approximately 333 patients in China will be randomized. The total study duration will be approximately 8 months including the enrolment period of approximately 7 months and the patient participation duration of 1 month or 4 weeks. Each patient will undergo a screening period of up to 1 week, a 1-week treatment period and a 2-week follow-up period. This study will be conducted in approximately 15-25 sites in China.
The aim of this study is to evaluate the impact of air pollution on the occurrence and clinical course of chronic respiratory diseases, and discover new biomarkers from various devices such as CT images that can indicate the process and amount of lung damage caused by air pollution. Accordingly, the investigators have designed an prospective cohort with enrollment of normal people and patients with chronic respiratory diseases of three different categories (chronic obstructive pulmonary disease, asthma, idiopathic pulmonary fibrosis). Participants will be followed up for a period of one year, with evaluation of the clinical course of the respiratory disease and exposure to air pollution.
3R aims to increase the access of patients with chronic respiratory diseases (CRD) to pulmonary rehabilitation (PR) in Portugal. The main goals of 3R are: i) design and implement an innovative community-based PR programme; ii) assess the cost-benefit of the community-based PR programme; iii) disseminate and perform knowledge transfer about PR across the country. PR is an evidence-based intervention for the management of CRD and offering PR has been defined as a priority by national/international organizations. However, in Portugal PR is practically inexistent (<1% of "candidate" patients have access). Currently, PR programmes are hospital-based and directed to patients with advanced disease. One of the recommendations to enhance the implementation of PR is the development on novel models of programme delivery. It is hypothesised that community-based programs, direct to patients at all grades of the disease, and involving all stakeholders (health professionals, patients, society, policy makers) may turn PR more accessible. The plan is to implement community-based PR programs in 4 primary care centres of 2 ACES of the centre region of Portugal and assess the impact of such intervention in several domains using surrogate and patient-/family-centered outcomes. A cost-benefit analysis will be performed on acute exacerbations and healthcare utilization. Dissemination will include one conference, activities with the community, courses and an online PR toolkit. Four schools of 2 polytechnics, 2 city councils, the Health Regional Administration-Centre (ARS-Centro) and all respiratory professional and civic national associations are partners.
