Since the first description of pulmonary circulation in the 16th century, the knowledge of the complex interaction between the heart and lungs has greatly improved. Hypoxemia plays a classical role in the development of complications such as pulmonary hypertension and right ventricle (RV) dysfunction in patients presenting with chronic obstructive pulmonary disease (COPD). However, more recent results have revealed the presence of RV vascular structural and functional changes even in patients with mild COPD, without hypoxemia or pulmonary hypertension at rest...

Long-term survivors of Hodgkin lymphoma (HL) experience several late adverse effects of treatment, with second malignant neoplasms (SMNs) and cardiovascular diseases (CVDs) being the leading causes of death in these patients. Other late effects have also been identified, such as pulmonary dysfunction, endocrinopathies (thyroid dysfunction, infertility), neck muscle atrophy, and persistent fatigue. HL survivors have two- to fourfold increased risks to develop SMNs and CVD compared with the general population...

Bronchopulmonary dysplasia (BPD) is a chronic lung injury characterized by impaired alveologenesis that may persist into adulthood. Rat models of BPD using varying degrees of hyperoxia to produce injury either cause early mortality or spontaneously recover following removal of the inciting stimulus, thus limiting clinical relevance. We sought to refine an established rat model induced by exposure to 60% O2 from birth by following hyperoxia with intermittent hypoxia (IH). Rats exposed from birth to air or 60% O2 until day 14 were recovered in air with or without IH (FiO2 = 0...

Connective tissue disease related pulmonary arterial hypertension (CTD-PAH) is characterized by vascular remodeling, endothelial dysfunction and inflammation. Endocan is a novel endothelial dysfunction marker. The aim of the present study was to investigate the role of endocan in CTD-PAH. Monocrotaline (MCT)-induced PAH rats were used as the CTD-PAH model. Short hairpin RNA packed in a lentiviral vector used to inhibit endocan expression was intratracheally instilled in rats prior to the MCT injection. Endocan was found to be increased in the serum and lung of MCT-induced PAH rats...

Pulmonary arterial hypertension (PAH) is characterized by enhanced proliferation of pulmonary artery smooth muscle cells and endothelial cells associated with obliteration of small pulmonary arterioles and formation of plexiform lesions. To date, no curative treatments have been identified for pulmonary arterial hypertension. There are various therapeutic options, including conventional medical therapies and oral, subcutaneous, intravenous, and inhalation delivery. We have previously shown that miR-143/145 knockout can prevent the development of chronic hypoxia-induced pulmonary hypertension (PH) in mice...

Pulmonary hypertension (PH) is a complex condition that can occur as a result of a wide range of disorders, including left heart disease, lung disease and chronic pulmonary thromboembolism. Contemporary PH patients are older and frequently have a multitude of comorbidities that may contribute to or simply coincide with their PH. Identifying the cause of PH in these complicated patients can be challenging but is essential, given that the aetiology of the disease has a significant impact on the management options available...

Pulmonary hypertension (PH) is characterized by an increase in PAPmean > 25 mmHg associated with a reduced life expectancy. Recent advances in the management of these patients provided the basis for the updated recommendations of the 2015 joint guidelines of the European Society of Cardiology (ESC) and the European Respiratory Society (ERS) on the diagnosis and treatment of pulmonary hypertension. The updated version includes important modifications with regards to hemodynamic definitions, clinical classification and diagnostic assessment of patients with PH...

To perform this meta-analysis, we investigated the risk of the most clinically relevant adverse events related to antivascular endothelial growth factor receptor (VEGFR) agents in advanced nonsmall-cell lung cancer (NSCLC).A comprehensive literature search for studies published up to October 2015 was performed. Prospective randomized controlled phase II/III clinical trials that comparing therapy with or without anti-VEGFR agents for advanced NSCLC were included for analysis. Summary relative risk (RR) and 95% confidence intervals (CIs) were calculated using random effects or fixed effects according to the heterogeneity among included trials...

Systemic sclerosis (SSc) is a systemic autoimmune disease characterized by vasculopathy, inflammation and fibrosis. These three main disease-determining pathways are the target of the currently available treatments used to possibly modify the progression of disease-related manifestations, although this synergy has not been fully applied on SSc joint, skin or lung involvement yet. Areas covered: we describe the current status of SSc treatment/therapy performing a literature search in MEDLINE/Pubmed and Thomson Reuter's Web of Science for articles published until March 2016...

Persistent tachypnea and failure to thrive during infancy have a broad differential diagnosis which includes pulmonary and cardiovascular disorders. Diffuse alveolar hemorrhage (DAH) is a rare entity in children. DAH requires an extensive work-up as certain conditions may need chronic therapy. Cardiovascular disorders are included in the etiology of DAH. We present a case of an 8-month-old female with a moderate, restrictive patent ductus arteriosus (PDA) admitted to the hospital with respiratory distress and failure to thrive...

BACKGROUND: Occupational and environmental exposure to crystalline silica may lead to the development of silicosis, which is characterized by inflammation and progressive fibrosis. A substantial number of patients diagnosed with silicosis develop pulmonary hypertension. Pulmonary hypertension associated with silicosis and with related restrictive lung diseases significantly reduces survival in affected subjects. An animal model of silicosis has been described previously however, the magnitude of vascular remodeling and hemodynamic effects of inhaled silica are largely unknown...

Chronic obstructive pulmonary disease (COPD) is a heterogeneous disease having small airway inflammation, emphysema, and pulmonary hypertension. It is now clear that spirometry alone cannot differentiate each component. Quantitative computed tomography (QCT) is increasingly used to quantify the amount of emphysema and small airway involvement in COPD. Inspiratory CT guides in assessing emphysema while expiratory CT identifies areas of air trapping which is a surrogate of small airway inflammation. By constructing a three-dimensional model of airways, we can also measure the airway wall thickness of segmental and subsegmental airways...

A 63-year-old man with sarcoidosis-associated pulmonary hypertension (SAPH) died suddenly of decompensated right heart failure. At autopsy, microscopy showed subpleural and interlobular fibrosis in both upper lobes, with marked broncho-bronchiolectasis, as well as bronchovascular bundle fibrosis and fibrotic organization in alveolar lumens, which are consistent with pulmonary sarcoidosis. Intimal fibrosis and medial hypertrophy were noted in the proximal elastic to distal muscular pulmonary arteries (Heath-Edwards, grades II-III) within intensive fibrotic lesions...

The classical definition of Chronic Obstructive Pulmonary Disease (COPD) as a lung condition characterized by irreversible airway obstruction is outdated. The systemic involvement in patients with COPD, as well as the interactions between COPD and its comorbidities, justify the description of chronic systemic inflammatory syndrome. The pathogenesis of COPD is closely linked with aging, as well as with cardiovascular, endocrine, musculoskeletal, renal, and gastrointestinal pathologies, decreasing the quality of life of patients with COPD and, furthermore, complicating the management of the disease...

The presence of systemic left-to-right shunt and increased pulmonary blood flow can result in right heart failure and pulmonary arteriopathy. Correction of left-to-right shunt has been shown to improve cardiac function and physical performance. However, the cardiopulmonary remodeling processes following cessation of left-to-right shunt have yet to be reported. In this experimental study, excessive pulmonary flow was restored through ligation of the aortocaval fistula in rats with flow-induced pulmonary hypertension...

Advances in the treatment of idiopathic interstitial pneumonia (IIP) represent an urgent, unmet medical need for patients with this category of diffuse parenchymal lung disease. IIPs involve varying combinations of fibrosis and inflammation of unknown cause and may be associated with pulmonary hypertension (PH). When it occurs, PH is associated with higher oxygen needs, greater functional impairment, and increased mortality. However, whether or when PH is a maladaptive versus adaptive phenomenon remains to be determined...

BACKGROUND: Whether dabigatran is associated with a lower risk of acute kidney injury (AKI) in patients with nonvalvular atrial fibrillation (NVAF) remains unknown. OBJECTIVES: The authors compared the risk of AKI in Asians with NVAF who were prescribed dabigatran versus warfarin. METHODS: The authors analyzed patients enrolled in the Taiwan nationwide retrospective cohort study from June 1, 2012, to December 31, 2013. Dabigatran and warfarin were taken by 7,702 and 7,885 NVAF patients without a history of chronic kidney disease (CKD) and 2,256 and 2,089 NVAF patients with a history of CKD, respectively...

Epigenetics plays an important role in the fetal origins of adult disease. Intrauterine growth retardation (IUGR) can cause increased histone acetylation of the endothelin-1 (ET-1) gene from pulmonary vascular endothelial cells or the whole lung tissue and persist into later life, likely resulting in increased risk of pulmonary hypertension or asthma later in life. However, little is known regarding the correlation of epigenetic changes between specific tissue and peripheral leucocytes. In the present study, an IUGR rat model was established by maternal nutrient restriction...

BACKGROUND: The incidence and prevalence of chronic kidney disease (CKD) continue to rise worldwide. Increasing age, diabetes, hypertension, and cigarette smoking are well-recognized risk factors for CKD. Chronic obstructive pulmonary disease (COPD) is characterized by chronic airway inflammation leading to airway obstruction and parenchymal lung destruction. Due to some of the common pathogenic mechanisms, COPD has been associated with increased prevalence of CKD. METHODS: Systematic review of medical literature reporting the incidence and prevalence of CKD in patients with COPD using the Cochrane Collaboration Methodology, and conduct meta-analysis to study the cumulative effect of the eligible studies...
