Filter by:The pathogenesis of idiopathic pulmonary fibrosis (IPF) is incompletely understood but recurrent epithelial injury occurs which evokes the coagulation cascade. Thrombin is produced as a result and is over expressed in IPF patients, so may be important in propagating disease activity. We aim to recruit patients with IPF and then complete FDG (18F-2-fluoro-2-deoxy-D-glucose fluorodeoxyglucose) PET (positron emission tomography) scans pre and post manipulation of the coagulation cascade to assess the role of this biological pathway in disease activity. Previous studies from our institution have demonstrated increased FDG avidity in the lungs of patients with IPF (assessed using FDG PET scans) but to date the cells and pathways responsible for this signal have not been identified and thus need further exploration.
Interstitial lung disease (ILD) is a common complication of dermatomyositis (DM) with prevalence up to 65%, and is considered to be one of the determining factors of prognosis. Clinical amyopathic dermatomyositis (CADM), which is a special phenotype of DM, with characteristic cutaneous manifestations but no or only subclinical myopathy. Many studies, mainly from Asia, including ours, have demonstrated that these patients with CADM tend to develop a rapidly progressive ILD (RPILD) and have a poor response to conventional therapy, such as high-dose corticosteroids and immunosuppressants, leading to lethal outcome with a 6-month survival rate of less than 50%. Pirfenidone, a new oral antifibrotic agent, has been approved for the treatment of idiopathic pulmonary fibrosis (IPF). Randomized controlled trials of pirfenidone in patients with IPF suggested that it could ameliorate pulmonary function decline and improve the progression-free survival. Its utility in connective tissue disease (CTD) related ILD has been implicated, but no evidence has yet demonstrated its efficacy. Therefore, the investigators conduct this study to evaluate the possible therapeutic effects of pirfenidone on RPILD associated with CADM.
Respiratory dysfunction following cardiac surgery is well documented and due in part to the location of the incision and nature of the surgery. Post-operative pulmonary complications (PPCs) remain a significant problem following cardiac surgery, sometimes causing prolonged length of stay in hospital as well as increased morbidity and mortality; with the greater risk to older adults and individuals with obstructive lung disease. Positive expiratory pressure (PEP) therapy is thought to increase lung volumes and facilitate secretion clearance. The purpose of this study is to investigate whether the addition of oscillating PEP therapy to standard postoperative treatment is more effective in decreasing the incidence of PPCs and increasing functional capacity at time of discharge in 'high risk' patients undergoing elective cardiac surgery.
prospective study, involves 60 patients underwent thoracoscopic surgery, the patients will be divided into two groups, the first group will undergo early chest tube removal - after three hours, the second group will have late chest tube removal according to the department's protocol. the study aims to prove the possibility and non inferiority for early chest tube removal for thoracoscopic surgeries with non complicated surgical course.
To characterize stem cell compartments in their niches in different clinical situations (non-diseased compared to emphysematous and fibrotic pulmonary tissue) and to assess their proliferative and developmental properties in vitro. To further implement lung organoid culture system in the drug screening and development of patient personalized medicine.
The trial shall assess the accuracy of the Oxitone® 1000 in measuring oxygen saturation, by comparing its measurement to reference devices: non-invasive SpO2 and pulse-rate values determined by a pulse oximeter. A total of approximately 40 subjects: 20 healthy and 20 COPD (chronic obstructive pulmonary disease ) patients will be enrolled. These subjects will be enrolled at the medical center pulmonary department and will be recruited from the clinic patient base. The subjects will be represented by male and female adults who optimally cover a range of ethnic backgrounds (skin pigmentation). All testing will be performed in singleton and in a blinded fashion. This study will be conducted with the approval of the medical center ethics committee. This is a comparison open study with no subject follow-up.
Evaluating the diagnostic value of transbronchial lung cryobiopsy (TBLC) as well as its procedural feasibility and safety in a prospective series of 20 patients with diffuse interstitial lung diseases (DILD) who are referred for invasive histopathological diagnostics
To evaluate the pulmonary gas exchange response to a therapeutic high dose of inhaled indacaterol (300 mcg) in 20 outpatients with stable symptomatic COPD B and D GOLD 2011 groups. Measurements on a single day before and after 60 and 120 minutes of indacaterol will include arterial PO2, PaCO2 and pH. AaPO2; SaO2 (by pulse oximetry) and oxygen and carbon dioxide in exhaled breath, systemic arterial pressure and heart rate will also be measured/calculated. Cardiac output will be directly measured by bio-impedance.
Chronic Obstructive Pulmonary Disease (COPD) is a frequent disease, with increasing prevalence. Pulmonary rehabilitation through general exercise training (GET) is a corner stone of COPD care. Inspiratory muscle training (IMT) as a stand-alone therapy decreases dyspnea and improves exercise capacity. Whether IMT combined with GET adds a supplementary benefit in the rehabilitation of COPD patients is however uncertain.
