OBJECTIVES: This study sought to compare the prognostic power of left ventricular end-diastolic pressure (LVEDP) and pulmonary arterial wedge pressure (PAWP) in heart failure with preserved ejection fraction (HFpEF). BACKGROUND: It is broadly accepted that direct measurement of LVEDP in HFpEF more robustly reflects left ventricular hemodynamics than PAWP. METHODS: A total of 173 consecutive HFpEF patients were prospectively enrolled. Of these, 152 patients fulfilled registry inclusion criteria...

BACKGROUND: Recent evidences show that Pulmonary Rehabilitation (PR) is effective in patients with Interstitial Lung Disease (ILD). It is still unclear whether disease severity and/or etiology might impact on the reported benefits. We designed this prospective study 1) to confirm the efficacy of rehabilitation in a population of patients with ILDs and 2) to investigate whether baseline exercise capacity, disease severity or ILD etiology might affect outcomes. METHODS: Forty-one patients (IPF 63%, age 66...

Introduction: Bilateral breast reduction surgery is the surgical treatment of bilateral breast hypertrophy. This is one of the most common breast surgery requested by women, and performed by plastic surgeons. The reasons that patients want this surgery are to re-size sagging breasts aesthetically, and to get rid of somatic symptoms such as shoulder, chest, back, and neck pain. We believe that the objective positive effects of breast reduction surgery exist beside aesthetic. In our study, our aim is to elicit positive effects of surgery on lungs, if there are, by making pulmonary function test and carbon monoxide diffusion test before surgery and after 6 months of surgery...

Ipilimumab, an immune checkpoint inhibitor, is approved for treatment metastastic melanoma and is a promising agent against other malignancies. There is some preliminary evidence from case reports that ipilimumab treatment may be associated with pulmonary side effects. However, data from prospective studies on ipilimumab-related pulmonary toxicity are still scarce. Serial spirometries and measurements of CO-diffusion capacity (DLCO) in patients with metastatic melanoma before and during treatment with ipilimumab were performed...

BACKGROUND: Idiopathic pulmonary fibrosis (IPF) is a progressive fibrosing lung disease of unknown etiology. Inter-society consensus guidelines on IPF diagnosis and management outline radiologic patterns including definite usual interstitial pneumonia (UIP), possible UIP, and inconsistent with UIP. We evaluate these diagnostic categories as prognostic markers among patients with IPF. METHODS: Included subjects had biopsy-proven UIP, a multidisciplinary team diagnosis of IPF, and a baseline high-resolution computed tomography (HRCT)...

BACKGROUND: Video-assisted thoracic surgery (VATS) emerged as a minimally invasive surgery for diseases in the field of thoracic surgery. We herein reviewed our experience on thoracoscopic lobectomy for early lung cancer and evaluated Health System use. METHODS: A cost-effectiveness study was performed comparing VATS vs. open thoracic surgery (OPEN) for lung cancer patients. Demographic data, tumor localization, dynamic pulmonary function tests [forced vital capacity (FVC), forced expiratory volume in one second (FEV1), diffusion capacity (DLCO) and maximal oxygen uptake (VO2max)], surgical approach, postoperative details, and complications were recorded and analyzed...

PURPOSE: A straightforward, noninvasive method is needed to assess emphysema and pulmonary hypertension (PH) in COPD patients. The desaturation-distance ratio (DDR) is an index derived from the distance traveled and level of desaturation during a six-minute walk test (6MWT); it has previously been shown to be associated with percentage of forced expiratory volume in the first second of expiration (%FEV1.0) and percentage of diffusion capacity of the lung for carbon monoxide (%DLCO). The aim of this study was to examine the associations between DDR and emphysema and PH...

PURPOSE: There has been suggestion that a greater "pulmonary vascular reserve" defined by a low pulmonary vascular resistance (PVR) and a high lung diffusing capacity (DL) allow for a superior aerobic exercise capacity. How pulmonary vascular reserve might affect exercise capacity at moderate altitude is not known. METHODS: Thirty-eight healthy subjects underwent an exercise stress echocardiography of the pulmonary circulation, combined with measurements of DL for nitric oxide (NO) and carbon monoxide (CO) and a cardiopulmonary exercise test at sea level and at an altitude of 2250 m...

REVIEW
Amy Hajari Case, Peace Johnson
Idiopathic pulmonary fibrosis (IPF) is a rare lung disease characterised by progressive loss of lung function, dyspnoea and cough. IPF has a variable clinical course but a poor prognosis. Nintedanib, a tyrosine kinase inhibitor, is one of two drugs approved for the treatment of IPF. In clinical trials, nintedanib slowed disease progression by reducing the rate of decline in forced vital capacity (FVC) in patients with IPF and mild or moderate lung function impairment. The effect of nintedanib was consistent across patient subgroups defined by baseline characteristics including FVC % predicted, diffusion capacity of the lung for carbon monoxide % predicted and the presence of emphysema...

Pulmonary Langerhans cell histiocytosis (PLCH) is a rare sporadic cystic lung disease of unknown aetiology that is characterised by the infiltration and destruction of the wall of distal bronchioles by CD1a(+) Langerhans-like cells. In adults, PLCH is frequently isolated and affects young smokers of both sexes. Recent multicentre studies have led to the more standardised management of patients in clinical practice. Smoking cessation is essential and is occasionally the only suitable intervention. Serial lung function testing is important because a significant proportion of patients may experience an early decline in forced expiratory volume in 1 s and develop airflow obstruction...

The clinical significance of serial changes in serum biomarkers in patients with idiopathic pulmonary fibrosis (IPF) remains to be established. This retrospective study was conducted to clarify the associations of serial changes in serum Krebs von den Lungen-6 (KL-6) and surfactant protein-D (SP-D) with changes in physiological indices and overall mortality in IPF. The study subjects were 75 patients with IPF. The 6 month change in serum KL-6 was significantly correlated with changes in the percentage of the predicted forced vital capacity (FVC % pred) and the percentage of the predicted diffusing capacity of the lung for carbon monoxide (% DLCO), while the 6 month change in serum SP-D was correlated only with % DLCO...

In this study, we aimed to determine the impact of lung transplantation (LTx) on pulmonary function tests (PFTs) and survival among patients with end-stage silicosis. We included patients with end-stage silicosis on the wait list for LTx, between January 1989 and July 2015 (N = 26). Sixteen of these patients received LTx; 10 were eligible, but did not undergo LTx (non-LTx) during the study period. Retrospective information on PFTs (spirometry [volumes and flows], 6-minute walking test [6MWT], and DLCO) was retrieved from patients' medical charts, including baseline information for all patients and follow-up information for the LTx...
