Analyses of immunity in pulmonary arterial hypertension (PAH) support the notion that maladaptation of the immune response exists. Altered immunity is an increasingly recognized feature of PAH. Indeed, a delicate balance between immunity and tolerance exists and any disturbance may result in chronic inflammation or autoimmunity. This is suggested by infiltration of various immune cells (e.g. macrophages, T and B lymphocytes) in remodeled pulmonary vessels. In addition, several types of autoantibodies directed against antinuclear antigens, endothelial cells (ECs) and fibroblasts have been found in idiopathic and systemic sclerosis-associated PAH...

Angiostrongylosis caused by metastrongyloid nematode Angiostrongylus vasorum is an emerging parasitic disease in Europe and the red fox (Vulpes vulpes) is considered as a main reservoir species for this parasite. Little is known about the role of other wild canids in the epidemiology of angiostrongylosis. The present paper provides the first description of pathomorphological lesions caused by A. vasorum in a golden jackal (Canis aureus). The paper describes a case of co-infection with A. vasorum and Dirofilaria immitis in a one-year-old female golden jackal, legally hunted near the City of Kovin, South Banat, Serbia...

BACKGROUND: Systemic sclerosis is a multisystem disorder characterized by microangiopathy, dysregulation of the immune system and massive deposition of collagen in the connective tissue of the skin, blood vessels and various internal organs. Although the mortality from renal crises has dropped significantly due to the use of angiotensin-converting enzyme inhibitors, cardiac and pulmonary involvement accounts for significant morbidity and mortality. We studied 28 patients with systemic sclerosis at Gandhi Medical College and Hospital, Hyderabad, over a period of two years for cardiopulmonary involvement...

The arterial roots are important transitional regions of the heart, connecting the intrapericardial components of the aortic and pulmonary trunks with their ventricular outlets. They house the arterial (semilunar) valves and, in the case of the aorta, are the points of coronary arterial attachment. Moreover, because of the semilunar attachments of the valve leaflets, the arterial roots span the anatomic ventriculo-arterial junction. By virtue of this arrangement, the interleaflet triangles, despite being fibrous, are found on the ventricular aspect of the root and located within the left ventricular cavity...

The data presented in this article are related to the research paper entitled "peroxiredoxin-2 plays a pivotal role as multimodal cytoprotector in the early phase of pulmonary hypertension" (Federti et al., 2017) [1]. Data show that the absence of peroxiredoxin-2 (Prx2) is associated with increased lung oxidation and pulmonary vascular endothelial dysfunction. Prx2(-/)(-) mice displayed activation of the redox-sensitive transcriptional factors, NF-kB and Nrf2, and increased expression of cytoprotective system such as heme-oxygenase-1 (HO-1)...

OBJECTIVE: To examine the safety and efficacy of contrast injection through a central venous catheter (CVC) for contrast-enhanced computed tomography (CECT). METHODS: A systematic literature search was performed using PubMed. Studies were deemed eligible if they reported on the use of CVCs for contrast administration. Selected articles were assessed for their relevance and risk of bias. Articles with low relevance and high risk of bias or both were excluded. Data from included articles was extracted...

The case of an 11-year-old male patient with truncus arteriosus is presented. The patient has a right aortic arch, a repaired truncus arteriosus, pulmonary artery stenosis, as well as conduit stenosis, with a complex surgical plan being discussed. In order to gather additional insight into the patient's anatomy prior to the surgery and to facilitate communication with the patient's parents, a three-dimensional (3D) model of his heart and main vessels was created from computed tomography data. Feedback was collected from different stakeholders...

REVIEW
John W Funder
Spironolactone has been marketed for over half a century as a 'potassium-sparing diuretic', used primarily in patients with ascites. With the realization that primary aldosteronism is the most common (5-13%) form of secondary hypertension, it has become widely used as a mineralocorticoid receptor antagonist. More recently, in the wake of the RALES trial, spironolactone in addition to standard therapy has been shown to be very beneficial in heart failure with a reduced ejection fraction. Despite the failure of the TOPCAT trial, spironolactone is being increasingly used in diastolic heart failure (i...

REVIEW
Ikuo Fukuda, Kazuyuki Daitoku
Acute pulmonary thromboembolism is a catastrophic event, especially for hospitalized patients. The prognosis of pulmonary thromboembolism depends on the degree of pulmonary arterial occlusion. The mortality of massive pulmonary embolism is reportedly as high as 25% without cardiopulmonary arrest and 65% with cardiopulmonary arrest. In patients with unstable hemodynamics due to pulmonary thromboembolism, surgical pulmonary embolectomy is indicated for patients with a contraindication to thrombolysis, failed catheter therapy, or failed thrombolysis...

REVIEW
Ayako Ro, Norimasa Kageyama, Toshiji Mukai
Here the pathophysiology of venous thromboembolism is reviewed with respect to the anatomical features of the deep veins of lower limbs. A thrombus is less likely to form in the thigh veins compared with that in the calf veins; however, clinical symptoms are more likely to appear in the thigh veins owing to vascular occlusion. When a patient is bedridden, thrombosis is more likely to occur in the intramuscular vein, which mainly depends on muscular pumping and the venous valve, rather than in the three crural branches, which mainly depends on the pulsation of the accompanying artery...

Anomalous left coronary artery arising from the pulmonary artery (ALCAPA) has been generally reported as an isolated lesion that is also called Bland-White-Garland syndrome. Herein we report a case of ALCAPA syndrome with an atrial septal defect in a 68-year-old woman. She had been asymptomatic until the age of 68. Echocardiographic examination revealed atrial septal defect, and coronary angiography showed that the left main coronary artery originated from the pulmonary artery and intensive collateral connections between the right and left coronary artery...

OBJECTIVE: To determine the anti-inflammatory efficacy of choline in vivo and in vitro and to investigate the anti-inflammatory mechanisms of choline. STUDY DESIGN: Randomized, controlled studies. ANIMALS: In vivo trials used 16 Romney sheep. In vitro experiments utilized RAW 264.7 mouse macrophage cells. METHODS: Hypoxaemia induced in 16 sheep by intravenous (IV) injection of 50 μg kg(-1) xylazine, an α-2 agonist, was measured in sheep at 0, 1 and 4 minutes using arterial blood gas analysis with and without 50 mg kg(-1) IV choline chloride premedication...

BACKGROUND: Sepsis is the leading cause of lung injury in adults and can lead to acute respiratory distress syndrome (ARDS). Using a novel technique of isolated in vivo lung perfusion (IVLP), we hypothesized that normothermic IVLP will improve oxygenation and compliance in a porcine model of sepsis-induced lung injury. METHODS: Mature adult swine (n = 8) were administered lipopolysaccharide (LPS; 50 μg/kg over 2 hours) via the external jugular vein, followed by sternotomy and central extracorporeal membrane oxygenation (ECMO) cannulation (right atrium to ascending aorta)...

BACKGROUND: Clinical and imaging manifestations are similar in pulmonary artery sarcomas (PAS) and thromboembolic diseases, especially central chronic pulmonary thromboembolism (CPTE). The feasibility of utilising clinical imaging tools such as computed tomography (CT) and magnetic resonance imaging (MRI) for differential diagnosis of PAS and CPTE has not been fully explored, especially MRI. METHODS: Patients with PAS (n=18) and central CPTE (n=20) treated at our hospital between January 2013 and September 2016 were identified retrospectively...
