Respiratory virus infections are one of the major causes of hospitalizations, and outbreaks of respiratory virus infection have led to severe economic loss. In addition to pulmonary complications, respiratory viruses can also lead to non-pulmonary complications. However, many previous studies on the complications of respiratory viruses are retrospective in nature, and therefore many patients with respiratory virus infection may not be tested. Furthermore, these studies did not take into account that respiratory viruses can be found in some asymptomatic individuals. The aim of this study is to capture the burden of respiratory viruses in patients with acute pulmonary and extrapulmonary complications. We will recruit patients admitted to our hospital with acute coronary syndrome, stroke and exacerbation of underlying lung diseases. We will collect saliva from these patients and test for respiratory viruses. As controls, we will recruit asymptomatic patients at the out-patient clinic for follow up of chronic heart, lung or neurological diseases. We anticipate that this study will greatly enhance our understanding of the epidemiology of respiratory viruses in acutely hospitalized patients. Our findings will be important for clinicians, public health practitioners and scientists.
This is an open-label, single-arm, multi-center, phase 2 Study to evaluate SHR-1210(anti-PD-1 antibody) in in adult Chinese patients with advanced or metastatic non-small cell lung cancer who failed or progressed to prior first-line systemic treatment. Enrolled subjects will be assigned to 4 cohorts on the basis of PD-L1 expression in tumor cells(<1%, ≥1%-25%, ≥25%-50%, ≥50%) all will be treated with the standard SHR-1210 dose (200mg) , Q2W, until documented progressive disease (PD) occurs. Subjects will return to the clinic once every two weeks. Radiographic disease assessments will be performed every 6 weeks. The primary study hypothesis is that treatment with SHR-1210 improves Objective Response Rate when compare with standard second-line therapy, no matter how much PD-L1 expression in tumor.
This study aims to assess the influence of exposure to swimming pool environment on respiratory symptoms and diseases, and on cancer outcomes among swimmers and swimming pool attendants.
The purpose of this study is to analysis the volatile organic gases(VOCs) in exhaled breath of pulmonary lesion patients and healthy controls, in order to find the difference of composition and concentration among groups.
Smoking is one of the world's leading health hazards. Besides being a major risk factor in the etiology of COPD and lung cancer, cigarette smoke is also a causative agent lung diseases characterized by bronchiolar and interstitial inflammation. However, the associated lung pathology of smoking is not only a risk in the development of lung diseases, but also widely recognized as a major risk factor associated with perioperative respiratory and cardiovascular complications. Apart from the long term effects of cigarette smoke, acute effects of the inhalation of cigarettes smoke may influence the course of lung pathology. The inhalation of smoke causes inflammation in the lung by inducing chemotaxis and activation of neutrophils and macrophages and induces oxidative stress. As the acute inflammatory response to smoke inhalation seems to be the underlying mechanism for chronic diseases of smokers, exploring the field of the acute pulmonary changes after exposure to cigarette smoke is highly relevant. One reason for acute hypoxia and injury during smoking might be a severe mismatch of ventilation and perfusion of the lung. Using the multiple inert gas elimination technique (MIGET), a distribution of ventilation-perfusion ratios in the lung can be calculated by analyzing data on the retention and excretion of six infused inert gases. A saline solution containing the gases is infused intravenously. When passing through the lung the gases are either eliminated from the blood or retained depending on their partition coefficient and local V/Q ratio. The concentrations of the gases are measured in the mixed venous blood or the mixed expired gas and the arterial blood allowing for the calculation of retention and excretion and the derivation of V/Q distribution. MIGET is the experimental gold standard to determine the Ventilation-Perfusion ratio of the lung. The aim of this study is to show the acute effect of smoking on ventilation/perfusion ratio distribution in the lung in otherwise healthy smokers.
Chronic Obstructive Pulmonary Disease (COPD) is a lung-related disorder that is characterized by long-term, often progressive state of poor airflow. Primary symptoms include low oxygen tension, shortness of breath, productive cough, and broncho-pulmonary inflammation and interference with oxygen-carbon dioxide exchange. Air pollution and tobacco smoking are felt to be the most common cause of these issues. Diagnostic testing is based on poor airflow measured by lung function studies and whose symptoms do not improve much with antiasthma bronchodilators. Study is an interventional study to document the safety and efficacy of use of AD-cSVF in chronic broncho-pulmonary disease groups.
The study consist of a retrospective analysis of the etiologies, investigations and outcomes of patients presenting between 2005 to 2010 with hemoptysis in a North-American Tertiary center.
This is a pilot study that seeks to evaluate the feasibility and safety of using a TEG algorithm in addition to traditional laboratory tests to guide transfusion and coagulation management of ECMO patients.
Shortness of breath (dyspnea) during exercise is a major source of distress and is a commonly reported symptom in patients with cystic fibrosis (CF). A recent treatment option known as Orkambi, which combines the drugs lumacaftor and ivacaftor, may be used in patients with CF to help improve lung health. However, the effects of this combination therapy on dyspnea and exercise performance, a known predictor of survival in CF, are not clear. The investigators aim to understand the effects of Orkambi on these symptoms and to gain new insight into the potential health improvements in CF from using this treatment option.
