Surgical removal of a tumour in the lung offers the best chance for survival in early stage lung cancers. One main criteria of surgical eligibility is the absence of cancer spread to the lymph nodes; rendering the staging process extremely important. The evaluation of these lymph nodes is thought to be best completed using Endobronchial Ultrasound (EBUS), a procedure in which several lymph nodes are sampled and send to pathology to determine whether or not it is malignant. More recently, studies have observed that there are clear differences in the characteristics of cancerous and benign (non-cancerous) lymph nodes, and so there has been great interest in creating a list of criteria that can determine whether a node is malignant. This study aims to prospectively validate a previously proposed score based on observed characteristics of lymph nodes during an EBUS procedure relating to pathology-confirmed results. To test this, the results of the lymph node samples and the observed score will be compared for agreement. If the investigators find that the scoring system can accurately predict which lymph nodes are cancerous, it would provide the evidence to establish the score as a standard procedure during cancer staging.
This is a Phase IV multi-center, randomized, open-label, cross-over, placebo study in subjects with Chronic Obstructive Pulmonary Disease (COPD) to compare inhaler-specific preference attributes of two inhalers - ELLIPTA dry powder inhaler (DPI) and the HANDIHALER DPI. The primary objective of this study is to evaluate whether more subjects with COPD prefer the ELLIPTA inhaler to the HANDIHALER DPI based on the number of steps needed to take medication. All subjects will use the ELLIPTA inhaler and the HANDIHALER inhaler in the corresponding treatment periods based on the randomisation scheme, and at the end of 2 periods, complete the inhaler preference questionnaire. Subjects will self-administer the inhalation once daily for 5-9 days in each treatment period. This study will be placebo-only, and neither inhaler will contain active treatment. Subjects will continue their current COPD medication(s) as prescribed, and will follow up with their regular physician for their COPD healthcare during the study. Approximately 211 subjects will be enrolled in the study. ELLIPTA is a trademark of the GlaxoSmithKline group of companies. HANDIHALER is a trademark of Boehringer Ingelheim International GmbH.
Prolonged antibiotic use in preterm neonates has significant consequences on the developing intestinal microbiome, metabolome and host response, predisposing the neonate to various major morbidities, including necrotizing enterocolitis (NEC), late-onset sepsis, bronchopulmonary dysplasia (BPD), and mortality. The hypothesis is that early and prolonged antibiotic use in preterm neonates has significant consequences on the developing intestinal microbiome, metabolome and host response, predisposing the neonate to various major morbidities. It is possible that the effect of this widespread antibiotic use outweighs the potential benefits. This study will randomize preterm infants born at less than 33 weeks gestation to either pre-emptive antibiotics or no-pre-emptive antibiotics. The purpose of this research is to evaluate the risks and benefits of current practice to determine optimal levels of antibiotic use that protects the babies from infection with minimal effect on the microbiome and subsequent adverse outcomes related to overuse of antibiotics.
1. To understand the components of PBMC in MAC-LD patients, including T cells, B cells, nature killer cells, and monocyte. 2. To confirm the phenomenon of reduced PBMC response in MAC-LD patients 3. To study the proportion of apoptosis and PD-1 expression in T cells among MAC-LD patients, MAC colonizers, patients with tuberculosis, and healthy controls. 4. To study the apoptosis and PD-1/PD-L1 expression in T cells/macrophage from bronchial lavage among MAC-LD patients, MAC colonizers, patients with tuberculosis, 5. To examine the PD-1 gene polymorphism and the correlation with MAC-LD.
Chronic obstructive pulmonary disease (COPD) affects up to 14 million people and is among the top five leading causes of death worldwide. Although COPD is a disease of the lungs, recent evidence indicates that COPD is associated with multiple systemic consequences including vascular endothelial dysfunction. Recently, it has been suggested that more patients with COPD die from cardiovascular disease and coronary heart disease than of direct pulmonary complications. Examination of the mechanisms that contribute to a reduction nitric oxide (NO) bioavailability resulting in vascular endothelial dysfunction in patients with COPD are important as endothelial dysfunction has been indicated to be an independent predictor of future atherosclerotic cardiovascular disease and events.
The main objective of EUREST-PLUS is to monitor and evaluate the impact of the Tobacco Products Directive (TPD) within the context of FCTC ratification at an EU level. The investigators specific objectives, within WorkPackage 2 and Workpackage 3 are: To evaluate the psychosocial and behavioral impact of TPD implementation and FCTC implementation, through the creation of a cohort study of adult smokers in 6 European Member States (EU MS), Germany, Greece, Hungary, Poland, Romania, Spain; (total n=6000) in a pre- vs. post-TPD study design. EUREST-PLUS is funded through the European Union's Horizon 2020 research and innovation programme under grant agreement No 681109
Preliminary evidence suggest that patients with chronic obstructive pulmonary disease (COPD) suffer from lower-limb muscle dysfunction. This may, at least in part, be due to a combination of physical inactivity and muscle oxidative stress. Pilot data (not published) clearly show that patients with COPD have significantly lower carnosine, which is a pH (acidity-basicity level) buffer and antioxidant, levels in the m. vastus lateralis compared to healthy subjects. Beta-alanine supplementation has shown to increase muscle carnosine in trained and untrained healthy subjects. This study will assess if muscle carnosine can be augmented by beta-alanine supplementation in 40 COPD patients (20 patients receive beta-alanine, 20 patients receive placebo). 10 healthy elderly controls will also be assessed to compare baseline muscle carnosine levels. The aims of this study are to: 1. Investigate baseline muscle carnosine levels to confirm the pilot data in a larger sample of patients with COPD compared with healthy elderly subjects 2. Investigate if beta-alanine supplementation augments muscle carnosine in COPD patients and whether it has an influence on exercise capacity, lower-limb muscle function and quality of life 3. To investigate baseline and post supplementation structural and metabolic muscle characteristics and markers of oxidative stress and inflammation in COPD patients and it's association with muscle carnosine levels
This is a Phase III randomized, double-blind, parallel group, multi-center, 24-week lung function study with BFF MDI (320/9.6 μg and 160/9.6 μg) compared to FF MDI 9.6 μg, BD MDI 320 μg, and open-label Symbicort® TBH (200/6 μg) administered BID.
Pathological comparisons of surgical open lung biopsies and cryobiopsies in non-IPF ILD. Patients with non-IPF ILD eligible for an open lung biopsy will undergo cryobiopsy in the same time. Between observers agreement will be assessed for each pairs of samples.
