BACKGROUND: The current functional guidelines recommend the shuttle walk test (SWT) as an initial screening tool to identify candidates for lung resection without requiring cardiopulmonary exercise testing. This study aims to: (I) assess the use of the SWT in predicting postoperative cardiopulmonary complications; and (II) determine whether the recommended 400 m cut-off is an appropriate distance. METHODS: We retrospectively analysed 101 patients that had performed a SWT prior to surgery...

BACKGROUND: IgG4-related disease (IgG4-RD) is an immune-mediated fibroinflammatory disorder that can affect most organs. To date, there have been no detailed assessments of pulmonary function in patients with IgG4-RD. In this study, we investigated pulmonary function in IgG4-RD patients and evaluated the value of pulmonary function tests (PFTs) in diagnosing IgG4-related respiratory disease (IgG4-RRD). METHODS: This was a retrospective study of 17 patients with IgG4-RD...

It is possible to model progression of influenza virus from the upper respiratory tract to the lower respiratory tract in the mouse using viral inoculum delivered in a restricted manner to the nose. In this model, infection with the A/Udorn/307/72 (Udorn) strain of virus results ultimately in high viral titres in both the trachea and lungs. In contrast, the A/Puerto Rico/8/34 (PR8) strain causes an infection that is almost entirely limited to the nasal passages. The factors that govern the progression of virus down the respiratory tract are not well understood...

A fully automated, unsupervised lobe segmentation algorithm is presented based on a probabilistic segmentation of the fissures and the simultaneous construction of a population model of the fissures. A two-class probabilistic segmentation segments the lung into candidate fissure voxels and the surrounding parenchyma. This was combined with anatomical information and a groupwise fissure prior to drive non-parametric surface fitting to obtain the final segmentation. The performance of our fissure segmentation was validated on 30 patients from the COPDGene cohort, achieving a high median F1-score of 0:90 and showed general insensitivity to filter parameters...

INTRODUCTION: Although there has been substantial emphasis on the neuromuscular and cardiovascular adaptations following rehabilitation, pulmonary adaptations in individuals with incomplete SCI (iSCI) in response to locomotor training have been less frequently studied. In healthy individuals, effective transition from rest to work is accomplished by a hyperpneic response, which exhibits an exponential curve with three phases. However, the degree to which our current understanding of exercise hyperpnea can be applied to individuals with iSCI is unknown...

Exercise intolerance is one of the clinical hallmarks of late-onset Pompe disease (LOPD). We studied the acute effects of ERT on the physiological variables associated with exercise tolerance in patients chronically ERT treated. Moreover, we assessed the influence of clinical severity on the investigated variables. The day before (B) and the day after (A) ERT injection, 11 LOPD patients performed on a cycle-ergometer an exercise tolerance test to voluntary exhaustion; VO2, HR, RPE, and GAA activity were determined in B and A...

OBJECTIVE: Acromegaly is associated with increased mortality due to respiratory disease. To date, lung function in patients with acromegaly has only been assessed in small studies, with contradicting results. We assessed lung function parameters in a large cohort of patients with acromegaly. DESIGN: Lung function of acromegaly patients was prospectively assessed using spirometry, blood gas analysis and body plethysmography. Biochemical indicators of acromegaly were assessed through measurement of growth hormone and IGF-I levels...

OBJECTIVE: Pulmonary carcinoma is one common malignant tumor with a high risk of recurrence and metastasis. Non-small cell lung cancer (NSCLC) is the most common subtype. As one tumor biomarker, microRNA (miR) has tissue sensitivity and can facilitate oncogene or inhibit tumor suppressor gene. MiR-218 has abnormal expression and can work as one molecular marker for tumors. However, its expression and function mechanism in lung cancer cells have not been fully illustrated. MATERIALS AND METHODS: In vitro cultured pulmonary adenoma A549 cells and normal bronchial epithelial cell line 16HBE were tested for miR-218 expression...

Mortality and morbidity attributed to asthma remains to be the biggest nightmare worldwide. Hence, the study was aimed to compare the cardio metabolic risk factors as assessed by Body mass index (BMI), waist hip ratio (WHR), serum triacylglycerol and uric acid in well controlled and poorly controlled asthmatics and to correlate these parameters with the severity of asthma. A case control study was conducted on 90 subjects who were segregated into well controlled asthmatics (n = 30) and poorly controlled asthmatics (n = 30) who were diagnosed based on Global initiative for Asthma management guidelines and healthy volunteers (n = 30)...
