Filter by:The pre-stage of Chronic Obstructive Pulmonary Disease (Pre-COPD) is challenging to diagnose. However, identifying Pre-COPD is a crucial step in the prevention and management of COPD. Endobronchial optical coherence tomography showed the value of diagnosis in Pre-COPD and COPD in previous researchs.
The overall aims of this protocol are to determine whether prenatal supplementation with vitamin C to pregnant smokers can improve pulmonary function at 10 years of age in their offspring. This is an additional continuation of the Vitamin C to Decrease Effects of Smoking in Pregnancy on Infant Lung Function (VCSIP) trial, to follow the offspring through 10 years of age. The hypothesis for this protocol is an extension of the VCSIP trial that supplemental vitamin C in pregnant smokers can significantly improve their children's airway function tests. The investigators aim to demonstrate sustained improvement in airway/pulmonary function and trajectory through 10 years of age.
So far, the number of COVID-19 infections worldwide has exceeded 700 million. Long-term damage to the lungs is a major sequela of COVID infection. Pulmonary function testing is an important means for the evaluation of lung damage. MRI examinations with free breathing and no contrast agent can prevent patients from suffering from ionizing radiation damage caused by multiple CT examinations.
At present, China is facing the first wave of COVID-19 epidemic after the liberalization. The infection rate has exceeded 50% in most areas, and even exceeded 80% in some cities. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) belongs to the beta genus of coronavirus and enters cells mainly by binding angiotensin converting enzyme 2 (ACE-2) to the spike protein on the envelope. The Omicron strain is the main epidemic strain at present. The transmission ability of Omicron strain is stronger than Delta strain, but the pathogenicity is weakened. At present, the published articles on the adjuvant treatment of COVID-19 with acupuncture are mostly theoretical discussions or case reports, and randomized controlled trials on the observation of curative effect are rare. The purpose of this study is to clarify the effectiveness of the adjuvant treatment of COVID-19 with acupuncture. Providing high-level research evidence for them.
The aims of this study are: 1. To determine the correlation between pulmonary functions and physical fitness in children with β-thalassemia. 2. To differentiate between different types of B-thalassemia in both pulmonary functions and physical fitness
Statement of the problem: Are there relations between smartphone addiction, neck posture, pulmonary functions and functional capacity in children? Null hypothesis It will be assumed that: - There will be no effect of smart phone addiction on head posture, pulmonary function and functional capacity in children. - There will be no relation between smartphone addiction, head posture, pulmonary function and functional capacity in children.
Cystic fibrosis (CF) is a rare autosomal recessive disease involving multiple organs, especially the lungs and digestive organs. It is most commonly seen in Caucasians. Only a few Chinese CF patients have been described in literature, taking into account the large population of China. The main objectives of this study are to accurately evaluate the prevalence of CF, the status of disease, the diagnosis and treatment, the quality of care, and the health related outcomes in China.
The current study aimed to investigate the effect of inspiratory muscle training (IMT) on pulmonary functions (FEV1and FVC), and respiratory muscle strength in patients with inhalation injury, which may prove to be a promising intervention helping to improve exercise tolerance, relieve dyspnea and suggests an improvement in respiratory muscle function.
In a randomized clinical trial (RCT) published in JAMA, the investigators have provided evidence that vitamin C supplementation (500 mg daily during pregnancy) ameliorates the effects of maternal smoking during pregnancy on offspring lung function and subsequent incidence of wheeze by 48% through 1 year of age. The investigators are currently completing a second RCT of vitamin C supplementation in pregnant smokers with more robust measures of pulmonary outcomes. The purpose of this ECHO application is to combine these 2 focused, interventional cohorts to allow critical longitudinal follow-up of respiratory outcomes in these children including the study of pulmonary function test (PFT) trajectories and incidence of recurrent wheeze/asthma from infancy through early adolescence in offspring of pregnant smokers randomized to vitamin C versus placebo.
The overall aims of this protocol are to determine whether prenatal supplementation with vitamin C to pregnant smokers can improve pulmonary function and decrease wheeze at 5 years of age in their offspring. This is a continuation of the VCSIP trial, to follow the offspring through 5 years of age. The hypothesis for this protocol is an extension of the VCSIP trial that supplemental vitamin C in pregnant smokers can significantly improve their children's PFTs and decrease the incidence of wheeze.
