The investigators' goal is to understand for what types of clinical questions real world data analyses can be conducted with confidence and how to implement such studies.
The primary objective of the study is to demonstrate that the ECCO2R pulsatile configuration prevents the Willebrand factor high molecular weight multimers decrease observed under continuous blood flow configurations. The secondary objectives are to quantify the CO2 extracorporeal removal in the pulsatile configuration, to describe complications (hemorrhagic, thrombotic and hemolytic), to describe patients' gas exchanges under ECCO2R, to describe the clinical course of the patients under ECCO2R as well as during the whole stay in the Intensive Care Unit (ICU).
This panel study aims to evaluate the effects of air pollutants on cardiopulmonary health of patients with chronic obstructive pulmonary disease (COPD) and explore the potential biological mechanisms.
Evaluation of immunogenicity and safety of the subjects aged 60 years and above with chronic bronchitis and chronic obstructive pulmonary disease recruited to receive the schedule of two doses inactivated COVID-19 vaccine with the interval of 21 days .
Evaluation of immunogenicity and safety of the subjects aged 60 years and above with chronic bronchitis and chronic obstructive pulmonary disease recruited to receive the schedule of three doses of inactivated COVID-19 vaccine on day 0, day 21 and day 111, respectively .
The risk factors and causes of chronic obstructive pulmonary disease（COPD）are not clear, so the prevalence of COPD is high and the prevention effect is not good. Because the pathogenesis of COPD is not completely elucidated, the diagnosis and classification of COPD are inaccurate which resulting in poor efficacy of treatment. Therefore, it is of great scientific and clinical significance to find out the risk factors and causes of COPD, to clarify its pathogenesis, to put forward the prevention and early intervention measures of COPD, to warn the occurrence of COPD, to predict the deterioration of the disease, to reduce the occurrence of COPD and to slow down the progress of COPD. The project establishes a cohort of COPD people，high-risk group and the healthy group. The project studys the risk factors, etiology and pathogenesis of COPD. The project studys the interaction between genetic factors and environmental factors on COPD and its effect on pathogenesis, progression and outcome of COPD.

Chronic Obstructive Pulmonary Disease (COPD) has a significant impact on one's quality and quantity of life resulting in increased morbidity and mortality. In Ireland, COPD has the highest hospital admissions in comparison to other countries within the organisation for economic cooperation and development (OECD). There is a need to improve knowledge and self-management behaviour in order to improve recognition of early signs of an exacerbation thereby seeking early treatment from the general practitioner (GP) thus reducing hospital admissions among this cohort . There are limited studies pertaining to the use of a comprehensive self-management programme via a smartphone app for people with COPD on a longitudinal basis.The aim of this study is to investigate the effectiveness of a smartphone application self-management programme on clinical health outcomes in patients with COPD.
Background: Initially conceived of as a method to address healthcare needs of underserved rural populations, Mobile Integrated Healthcare and Community Paramedicine (MIH/CP) is a new model of inter-professional, community-based outpatient healthcare delivery that primarily utilizes the resources and training of Emergency Medical Services (EMS) to fill gaps in local healthcare infrastructure, expanding existing scope of practice in most cases while not detracting from acute transport capabilities. Although programs have been in existence since the early 1990s, there are few objective studies of the efficacy, safety, and cost-effectiveness of MIH/CP programs, many of which are limited-scope pilot projects. The limited data already published on these measures by established programs shows substantial Medicare charge-avoidances in patients enrolled in CHF-readmission prevention and EMS frequent user programs, and a significant reduction in Emergency Department visits overall, especially in austere environments. In summary, MIH/CP is an attempt at formalization of long-standing practices to collaborate with and supplement other healthcare system components such as primary care and home health services. Standardized, objective data collection and publication of results will be needed to support continuation and financial support of this emerging concept. Objective/Hypothesis: Using the existing resources of the MD-, RN- and Paramedic-staffed Lifespan Pediatric and Adult Critical Care Transport (LifePACT) service, investigators aim to study whether implementation of an MIH/CP pilot program tailored to the needs of an urban, underserved population in Providence, Rhode Island, will reduce the rate of 30-day hospital readmissions for patients after discharges for community-acquired pneumonia, acute MI, and COPD. In addition, investigators will study whether such a program is considered to be safe (in terms of not increasing the number of adverse events post-discharge for patients or compromising the efficacy of the LifePACT transport role) and considered satisfactory by patients (rated comparably to visits by other outpatient health care services such as VNA services).
Chronic obstructive pulmonary disease (COPD) is a condition characterized by airway obstruction. Patients with COPD experience significant shortness of breath on exertion. The mechanisms responsible for shortness of breath on exertion are well understood in moderate and severe COPD, but, are poorly understood in mild COPD where symptoms appear disproportionate to the degree of airway obstruction. Mild COPD patients show an exaggerated breathing response to exercise, determined by the breathing response to carbon dioxide production (V̇E/V̇CO2). Recent work suggests that the increased V̇E/V̇CO2 during exercise in mild COPD is secondary to increased deadspace (i.e. lung regions with ventilation but no perfusion) and/or ventilation/perfusion (V̇A/Q) inequality (poor matching of ventilation to perfusion). Researchers have proposed that the increased deadspace or V̇A/Q inequality is secondary to pulmonary vascular dysfunction and hypoperfusion of the pulmonary capillaries. Recently, we have shown that inhaled nitric oxide, a potent dilator of pulmonary vasculature, reduces shortness of breath and V̇E/V̇CO2, and improves exercise capacity in mild COPD. This preliminary finding suggests that pulmonary vascular dysfunction is an important contributor to exercise intolerance in mild COPD. Here, we aim to test whether sildenafil, an oral pulmonary vasodilator, can improve exercise tolerance and shortness of breath in mild COPD.
