Objectives: SSc-pulmonary arterial hypertension (SSc-PAH) is associated with worse response to therapy and survival when compared with idiopathic PAH. It is suggested that the vasculopathy in SSc may involve postcapillary pulmonary venules resulting in pulmonary veno-occlusive disease (PVOD). This may underlie the lower gas transfer and worse outcome on therapy. We sought to test whether CT signs of PVOD (CTS-PVOD) were frequent in SSc-PAH and whether they were associated with pulmonary oedema on therapy and worse survival...

Background: Cardiovascular disease (CVD) is expected to contribute a large non-communicable disease burden amongst HIV-positive people. We quantify the impact of prevention interventions on annual CVD burden and costs amongst HIV-positive people in The Netherlands. Methods: We constructed an individual-based model of CVD in HIV-positive people using national ATHENA cohort data on 8,791 patients on combination antiretroviral therapy (cART). The model follows patients as they age, develop CVD (by incorporating a CVD risk equation) and start cardiovascular medication...

The effects of pulmonary hypertension (PAH) on survival after heart transplantation are debated, especially for patients with left ventricular assist devices (LVAD). The United Network of Organ Sharing database was retrospectively queried from January 2005 to June 2015 to identify adult patients who underwent heart transplantation. Four groups were defined: patients without PAH, persistent PAH, resolved PAH, and developed PAH between listing and transplant. A total of 15,914 patients underwent heart transplant of which 4,662 (29%) were implanted with an LVAD...

Combination of metolazone (0.5 mg) and valsartan (80 mg) has been verified as a promising therapy treatment for hypertension. In order to facilitate to pharmacokinetic research, it needs a method for the simultaneously determination of metolazone and valsartan in biological samples. However, there are no relative reports so far. In order to facilitate to pharmacokinetic research, an on-line solid phase extraction coupled with liquid chromatography-tandem mass spectrometry method for the simultaneous determination of metolazone and valsartan in beagle dog plasma was developed and validated in this study...

Biomarkers are increasingly being investigated in the treatment of pulmonary vascular disease. In particular, the signaling pathways targeted by therapies for pulmonary arterial hypertension provide biomarkers that potentially can be used to guide therapy and to assess clinical response as an alternative to invasive procedures such as right-sided cardiac catheterization. Moreover, the growing use of combination therapy for both the initial and subsequent treatment of pulmonary arterial hypertension highlights the need for biomarkers in this treatment approach...

Hypertension can originate from early-life insults, whereas maternal melatonin therapy can be protective in a variety of models of programmed hypertension. We hypothesize that melatonin or melatonin receptor agonist agomelatine can prevent programmed hypertension in adult offspring induced by maternal exposure to continuous light. Female Sprague-Dawley pregnant rats randomly divided into four groups: controls, rats exposed to continuous light, exposed to continuous light plus treated with agomelatine (50mg/day i...

PURPOSE OF REVIEW: In recent years, an interest in intestinal microbiota-host interactions has increased due to many findings about the impact of gut bacteria on human health and disease. Dysbiosis, a change in the composition of the gut microbiota, has been associated with much pathology, including cardiovascular diseases (CVD). This article will review normal functions of the gut microbiome, its link to CVD, and potential therapeutic interventions. RECENT FINDINGS: The recently discovered contribution of gut microbiota-derived molecules in the development of heart disease and its risk factors has significantly increased attention towards the connection between our gut and heart...

Pulmonary hypertension (PH) is a disease characterized by progressive adverse remodeling of the distal pulmonary arteries, resulting in elevated pulmonary vascular resistance and load pressure on the right ventricle (RV), ultimately leading to RV failure. Invasive hemodynamic testing is the gold standard for diagnosing PH, and guiding patient therapy. We hypothesized that lumped-parameter and biventricular finite-element (FE) modeling may lead to noninvasive predictions of both PH-related hemodynamic and biomechanical parameters that induce PH...

BACKGROUND: Idiopathic Intracranial Hypertension (IIH) is characterised by raised intracranial pressure (ICP) with normal cerebrospinal fluid (CSF) composition and absence of hydrocephalus or space occupying lesions. IIH is a rare disease in children. It can lead to visual impairment but prompt diagnosis and treatment in most of the cases will prevent potentially permanent visual loss. OBJECTIVE: To report a rare case of Idiopathic Intracranial Hypertension in a pubertal child, clinical features, and findings of Magnetic Resonance Imaging (MRI) and visual field of this case...

Background: Translocation of microbial products from the damaged gut causes increased immune activation in human immunodeficiency virus (HIV). Proton pump inhibitors (PPIs) predispose to bacterial overgrowth in the gut. We hypothesized that long-term use of PPIs is associated with greater microbial translocation and immune activation in HIV. Methods: HIV-infected persons on suppressive antiretroviral therapy (ART), including those receiving long-term PPIs (PPI+ group) or not (PPI- group), were enrolled...

BACKGROUND: Central nervous system (CNS) complications are increasingly noted in liver transplanted (LTx) hereditary transthyretin amyloid (ATTRm) amyloidosis patients; this suggests that the increased survival allows for intracranial ATTRm formation from brain synthesised mutant TTR. However, atrial fibrillation (AF), a recognised risk factor for ischemic CNS complications, is also observed after LTx. The aim of the study was to investigate the occurrence of CNS complications and AF in LTx ATTRm amyloidosis patients...

Chronic venous insufficiency is characterized by cutaneous alterations caused by venous hypertension; in severe forms, it progresses to lower limb ulcers. Lower limb varicose veins are the main cause of chronic venous insufficiency, and the classic treatment includes surgery and compressive therapy. Minimally invasive alternative treatments for varicose veins include new techniques such as venous thermal ablation using laser or radiofrequency. The use of different methods depends on clinical and anatomical factors...

Hydralazine is used in treatment of essential hypertension and is under investigation for epigenetic therapy in the treatment of neoplastic and renal diseases. N-acetyltransferase 2 (NAT2) exhibits a common genetic polymorphism in human populations. Following recombinant expression in yeast, human NAT2 exhibited an apparent Km (20.1 ± 8.8 μM) for hydralazine over 20-fold lower than the apparent Km (456 ± 57 μM) for recombinant human NAT1 (p=0.0016). The apparent Vmax for recombinant human NAT1 (72.2 ± 17...

This study examined characteristics and treatment persistence among patients prescribed oral anticoagulants (OACs) for stroke prevention in non-valvular atrial fibrillation (NVAF). We identified 15,244 patients (51.8% male, 72.7% aged ≥70) with NVAF and no prior OAC therapy who were prescribed apixaban (n = 1,303), rivaroxaban (n = 5,742), dabigatran (n = 1,622) or vitamin-K antagonists (VKAs, n = 6,577) between 1-Dec-2012 and 31-Oct-2014 in German primary care (IMS® Disease Analyzer). We compared OAC persistence using Cox regression over patients' entire follow-up and using a data-driven time-partitioned approach (before/after 100 days) to handle non-proportional hazards...
