Filter by:Particulate matter (PM) associated cardiorespiratory and vascular dysfunction (CaRVD) poses a significant global health burden. The World Trade Center (WTC) destruction on September 11, 2001 led to an intense deposition of particulate matter (WTC-PM) into aerodigestive system. WTC associated morbidities include respiratory, gastrointestinal, chronic rhinosinusitis, cancer, mental health concerns and more recently a focus has been on cardiovascular disease. This proposal will investigate the development of WTC-cardiorespiratory and vascular dysfunction (WTC-CaRVD) which is firmly within the purview of the James Zadroga 9/11 Health and Compensation Act. WTC-PM exposure causes heterogeneous obstructive airways disease (OAD) patterns, which include airway hyperreactivity (AHR) and loss of FEV1. Early diagnosis and therapeutic options are few, in part due to limited understanding of their pathogenesis. While pulmonary vascular changes are classically thought to occur due to the hypoxemia of late OAD, recent investigations show that vascular dysfunction occurs early in OAD. This vascular hypothesis of OAD postulates that pulmonary vasculature remodeling leads to loss of lung function. Early evidence of WTC-CaRVD includes increased prevalence of cardiovascular disease risk factors such as metabolic syndrome, elevated pulmonary artery/aorta ratio, and cardiovascular biomarkers (such as CRP). Murine models of WTC-PM exposure show inflammation, AHR both acutely and persistently and reflect what is seen in FDNY 1st responders. Airway and cardiac remodeling were also persistent features of WTC-PM exposure in the study team's murine models. Therefore, the study team will focus on Heme Oxygenase-1 (HO-1), a mediator of oxidative stress, known to stimulate collagen formation and is also induced after WTC-PM exposure. Furthermore, pathways and mechanisms of WTC-CaRVD warrant further study and are the focus of the 5-year proposal. The HYPOTHESIS is that WTC-PM exposure causes WTC-CaRVD mediated by HO-1. First responders with AHR will have features of WTC-CaRVD, and will demonstrate a unique biomarker profile compared to controls.
The aim of this study is to estimate level of IL 6 in COPD patients and its relation to COPD severity and acute exacerbation.
Chronic obstructive pulmonary disease (COPD) is characterized by persistent respiratory symptoms (including breathlessness, cough, and sputum production), which has a substantial impact on health-related quality of life (HRQoL). Medical treatment of COPD aims to reduce these symptoms, reduce exacerbations, and improve patients' ability to perform exercise and daily activities. TRIXEO is a triple therapy indicated as a maintenance treatment in adult patients with moderate-to-severe COPD who are not adequately treated by a combination of an inhaled corticosteroid and a long-acting beta2-agonist or combination of a long-acting beta2-agonist and a long-acting muscarinic antagonist. The RECORD study is a prospective, non-interventional study to be conducted in the United Kingdom (UK) and Germany. The study aims to generate data to describe the real world effectiveness of Trixeo for patients with COPD who receive Trixeo in routine clinical practice. It also aims describe patients HRQoL, physical activity and treatment satisfaction, and will explore patients' sleep quality and adherence to inhalers in the real-world. This data may provide important information for practicing physicians. The study will include approximately 500 patients with moderate to severe COPD from approximately 50 sites (including hospitals and GP practices) in the UK. Patients eligible for TRIXEO therapy may be enrolled by their treating physicians. The decision to treat with TRIXEO must be independent of the study and made by the treating physician according to the patients' medical need and local routine clinical practice. Patients data will be collected for 12 months after starting therapy with Trixeo. Demographic and clinical data will be extracted from patients' health care records. Patient reported outcomes will be collected remotely by asking patients to answer questionnaires on health status and HRQoL, treatment satisfaction, and inhaled medication adherence through electronic surveys. Consenting patients´ physical activity and sleep data will be collected via a Fitbit armband device.
Chronic Obstructive Pulmonary Disease (COPD) is a common chronic respiratory disease, causing disabling respiratory symptoms and impairing patients' quality of life. Currently one of the leading causes of death worldwide, COPD is a major socio-economic concern. It is also accompanied by extremely frequent extra-respiratory manifestations (or co-morbidities). Among these secondary manifestations, the equilibrium of these patients is subject to modifications: thus, numerous studies have shown that the equilibrium of COPD patients was altered compared to healthy age-matched subjects. This alteration is associated with a greater functional limitation and a higher risk of falling. Although this impairment has been demonstrated clinically, the balance of these patients has never been analysed using quantified movement analysis tools during tasks similar to those performed in daily life. Moreover, the underlying mechanisms remain unknown and the possible associations with several clinical factors of interest (pain, dyspnea, muscle function...) have not yet been assessed. The hypotheses of this project are that (1) the postural control of COPD patients is altered compared to healthy subjects during tasks of daily living and these changes can be characterised. (2) Several clinical factors are associated with these changes.
This is a two-armed, parallel-design, pre-/post-intervention assessment study. The investigators will conduct a randomized controlled trial for ED GOAL on a cohort of 120 older adults with serious illness to collect patient-centered outcomes and determine preliminary efficacy on increasing advance care planning engagement (self-reported and/or in the electronic medical record) one month after leaving the emergency department. The investigators will also conduct qualitative interviews with participants of ED GOAL.
Chronic obstructive pulmonary disease(COPD) is an incompletely reversible and progressive pulmonary disease characterized by airflow restriction, which is the third leading cause of death worldwide, accounting for 6% of all deaths worldwide. Acute exacerbation (AE) of COPD can accelerate the decline of lung function, worsening pulmonary symptoms, and increase the risk of death in patients. Health education, inhaled technical guidance training, individual self-management, psychological counseling, home oxygen therapy, nutritional support, and other comprehensive interventions can help improve the lung function of COPD patients, alleviate clinical symptoms, improve the quality of life. While a number of COPD applications have been developed, few provide comprehensive assessment and guidance for these kinds of patients. Therefore, the investigators aim to establish a bundle care mode based on the mode of "hospital-home-community-patient", clarify the impact of the management on prognosis, and evaluate the effect of mobile medical-assisted bundle management mode. In this randomized controlled trial(RCT), AECOPD patients will be divided into interventional or control groups randomly. Patients in the interventional group will receive mobile medication and standard of care at the same time (bundle care mode). While patients in the control group will receive standard of care only (traditional management mode). This study will be conducted to compare the effects of traditional and bundle care modes, and to formulate the implementation path and specifications of bundle care for AECOPD patients after discharge in China.
The purpose of this study is to test whether breathing control exercises embedded in occupational therapy sessions have an impact on quality of life and dyspnea in patients with chronic obstructive pulmonary disease (COPD).
The objective of the study is to evaluate the efficacy of home High Flow Oxygen for the reduction of severe exacerbation following admission for a severe exacerbation of COPD or death against standard oxygen therapy.
COPD patients often experience multiple symptoms (e.g. dyspnea, cough, and deteriorating quality of life) and have imposed a substantial economic and social burden on health care. The current proposal is to evaluate the feasibility and acceptability of a pilot trial of a smartphone-based instant messaging self-management support program to improve the quality of life in patients with COPD.
Background: In non-invasive cardiopulmonary exercise testing (CPET), oxygen pulse (O2P) is defined as oxygen uptake divided by heart rate and is equal to the product of stroke volume and oxygen extraction by cells. As per, the O2P indicates the capability of oxygen consumption of whole body tissues and cells per heart beat. During exercise, the O2P changes can be deemed as the stroke volume changes as the oxygen extraction by muscle cells are normal. Hence, CPET-O2P can be non-invasively and continuously used to monitor the stroke volume changes during exercise. O2P value (i.e., % of predicted) is related to the severity and prognosis of heart failure and to the severity of constraint of the heart caused by exercise-induced hyperinflation or air trapping in patients with chronic obstructive pulmonary disease (COPD). However, O2P plateau pattern is not uncommonly encountered in the daily practice. Hypothesis and aims: O2P patterns during incremental exercise are seldom investigated although they have been hypothesized that the plateau or decreasing patterns are related to myocardial failure or ischemia. In this proposal, the O2P patterns are to be thoroughly investigated: (1) the patterns in norms, patients with heart failure and COPD, (2) the relationship between the O2P pattern and cardiac function and/or myocardial ischemia in patients with heart failure and COPD. As yet there are no relative reports on the O2P pattern and its possible mechanisms in the literature, the results of the proposal might tremendously impact the interpretation strategy of CPET reports. Methods: Multidisciplinary, prospective, comparative cross-sectional study is designed. Subjects aged from 40-85 years with the BMI of 18-28kg/m2 are to be enrolled: sample sizes of the norms, heart failure and COPD groups are 10, 20, and 20, respectively, equally distributed in two years. The definitions of COPD and heart failure with NYHA class I-III are according to the GOLD and ESC guidelines, respectively。All the three groups undergo CPET-NIRS, echocardiography, and the first pass and myocardial perfusion studies using Tc-99. The primary measurements are the O2P patterns and the cardiac function measured with echocardiography, the first pass and myocardial perfusion studies and air trapping in the lungs.。 Statistical analysis: For normal continuous data, t-test or ANOVA is used. For non-normal data, the Mann-Whitney test is used. The chi-square test or Fisher's exact test is used to compare the proportion of categorical variables between the two groups. A p value of less than .05 is considered to be statistically significant. Statistical procedures are performed using the SAS software package version 9.3.
