Aims: Survival in pulmonary hypertension (PH) relates to right ventricular (RV) function. However, the RV unique anatomy and structure limit 2D analysis and its regional 3D function has not been studied yet. The aim of this study was to assess the implications of global and regional 3D RV deformation on clinical condition and survival in adults with PH and healthy controls. Methods and results: We collected a prospective longitudinal cohort of 104 consecutive PH patients and 34 healthy controls between September 2014 and December 2015...

NOTCH is a fundamental signaling system that regulates normal embryonic development and tissue homeostasis in adult life. NOTCH receptor is a single-pass transmembrane protein normally triggered via direct cell-to-cell contact, in which NOTCH ligands bind the extracellular domain of the receptor, inducing γ-secretase cleavage and release of intracellular domain. The intracellular domain binds to the transcriptional effector RBPJκ to activate transcription of target genes that regulate cell differentiation, patterning, and morphogenesis during embryonic development and adult life...

REVIEW
Jennifer J DuPont, Iris Z Jaffe
Since the mineralocorticoid receptor (MR) was cloned 30 years ago, it has become clear that MR is expressed in extra-renal tissues, including the cardiovascular system, where it is expressed in all cells of the vasculature. Understanding the role of MR in the vasculature has been of particular interest as clinical trials show that MR antagonism improves cardiovascular outcomes out of proportion to changes in blood pressure. The last 30 years of research have demonstrated that MR is a functional hormone-activated transcription factor in vascular smooth muscle cells and endothelial cells...

The Potts operation is a surgical option for the treatment of children with suprasystemic pulmonary arterial hypertension (PAH). Its positive hemodynamic effect may be obliterated by pulmonary valvar insufficiency. We describe a case in which the Potts shunt was followed by perventricular Melody valve implantation in the pulmonary position in a 12-kg child with a previously repaired truncus arteriosus communis (TAC) in whom PAH developed. The combined approach using both procedures significantly improved functional capacity and led to spectacular reverse remodeling of the right ventricle seen at 2-year follow-up...

Swimming-induced pulmonary edema (SIPE) has been described in sports and military medicine during strenuous swimming in open water. Symptoms include dyspnea, cough, frothy mucus and hemoptysis. Hypertension, a tight wetsuit, overhydration and previous episodes of SIPE are suggested risk factors. Immediate interruption of swimming prevents more serious symptoms. In the open water race at Vansbro 2016, 69 swimmers (of 13,878 in total) were treated for symptoms suspected for SIPE. Continuous positive airway pressure (CPAP) was successfully used to treat suspected SIPE in 46 patients in the on-site emergency care center...

Within the cohort of patients suffering from idiopathic pulmonary arterial hypertension (IPAH) is a group that responds dramatically (VR-PAH) to an acute vasodilator challenge and that has excellent long-term hemodynamic improvement and prognosis on high dose calcium channel blockers compared with vasodilator non-responders (VN-PAH). For the purposes of diagnosing VR-PAH, there is to date no test to replace the acute vasodilator challenge. However, recent studies have identified markers that may aid in the identification of VR-PAH, including peripheral blood lymphocyte RNA expression levels of desmogelin-2 and Ras homolog gene family member Q, and plasma levels of provirus integration site for Moloney murine leukemia virus...

We aimed to investigate the efficacy of four severity-of-disease scoring systems in predicting the 28-day survival rate among patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) requiring emergency care. Clinical data of patients with AECOPD who required emergency care were recorded over 2 years. APACHE II, SAPS II, SOFA, and MEDS scores were calculated from severity-of-disease indicators recorded at admission and compared between patients who died within 28 days of admission (death group; 46 patients) and those who did not (survival group; 336 patients)...

REVIEW
Sergio Harari, Davide Elia, Marc Humbert
Pulmonary hypertension (PH) due to chronic lung diseases is associated with a poor prognosis, regardless of the underlying respiratory condition. Updated PH guidelines recommend optimal treatment of the underlying lung disease, including long-term oxygen therapy, in patients with chronic hypoxaemia despite the lack of randomized controlled clinical trials supporting this statement. So far, randomized controlled trials on drugs approved for pulmonary arterial hypertension (PAH) have yielded discouraging results in both interstitial lung diseases (ILD) and chronic obstructive pulmonary diseases (COPD) with PH...

Combination treatment with endothelin receptor antagonists (ERA) and phosphodiesterase 5 inhibitors (PDE5I) improved efficacy of pulmonary arterial hypertension (PAH) therapy. However, drug-drug interactions, variable exposure, non-adherence can influence plasma levels. For these reasons, drug quantification may be advantageous particularly in patients with poor treatment responses. We developed, validated, and applied an assay for the simultaneous quantification of ambrisentan, bosentan, macitentan, sildenafil, and tadalafil as well as their main (and partly active) metabolites in human plasma...
