Blood Purif 2018 Dec 6:1-6. Epub 2018 Dec 6.
Renal Research Institute, New York, New York, USA.
Background: The time between the creation of an arteriovenous fistula (AVF) and its successful use is significantly longer in hemodialysis (HD) patients in the United States compared to those in other countries, and there is an urgent need to reduce the residence time of central-venous catheters (CVC).
Methods: Successful AVF creation and maturation results in typical hemodynamic changes, such as an increase in cardiac output and upper body blood flow (UBBF). In patients with CVC as vascular access, we measured once per minute intradialytic central-venous oxygen saturation (ScvO2) and hemoglobin levels simultaneously using the Crit-Line Monitor. Read More

Background: The impact of hybrid therapy comprising peritoneal dialysis (PD) and hemodialysis on cardiovascular events in PD patients remains unclear.
Objective: We aimed to evaluate the effect of hybrid therapy on cardiovascular events.
Methods: A total of 93 PD patients undergoing hybrid therapy for ≥3 years were divided into 2 groups according to left ventricular ejection fraction (LVEF): lower ejection fraction (LEF [n = 29], LVEF < 60%) and normal ejection fraction (NEF [n = 64], LVEF ≥60%). Read More

Background: Central venous oxygen saturation (ScvO2) is correlated with cardiac output. In most patients, ScvO2 declines during hemodialysis (HD) due to factors such as reduced preload, myocardial stunning, and intermittent arrhythmias. Previous research has shown that low ScvO2 is associated with higher mortality in chronic HD patients. Read More

Ivabradine is most commonly used for the treatment of worsening cardiac failure in patients who cannot tolerate the maximum dose of β-blockers or in whom treatment with β-blockers is contraindicated. While ivabradine is regarded as a highly selective "funny current" (I) inhibitor, the molecular mechanism behind the effect of this drug remains poorly understood. In the present study, we applied ivabradine in the context of osteoarthritis by treating primary human chondrocytes with tumor necrosis factor-α (TNF-α) and measuring degradation of the articular cartilage matrix as well as the expression of various enzymes and pro-inflammatory cytokines.

The sympathetic nervous system is the main stimulator of cardiac function. While acute activation of the β-adrenoceptors exerts positive inotropic and lusitropic effects by increasing cAMP and Ca, chronically enhanced sympathetic tone with changed β-adrenergic signaling leads to alterations of gene expression and remodeling. The CREB-regulated transcription coactivator 1 (CRTC1) is activated by cAMP and Ca. Read More

Purpose: Modern non-invasive evaluation of Coronary Artery Disease (CAD) requires non-contrast low dose Computed Tomography (CT) imaging for determination of Calcium Scoring (CACS) and contrast-enhanced imaging for evaluation of vascular stenosis. Several methods for calculation of CACS from contrast-enhanced images have been proposed before. The main principle for that is generation of virtual non-contrast images by iodine subtraction from a contrast-enhanced spectral CT dataset. Read More

Increased proinflammatory interleukin-6 (IL-6) levels are associated with acquired long QT-syndrome (LQTS) in patients with systemic inflammation, leading to higher risks for life-threatening polymorphic ventricular tachycardia such as Torsades de Pointes. However, the functional and molecular mechanisms of this association are not known. In most cases of acquired LQTS, the target ion channel is the human ether-á-go-go-related gene (hERG) encoding the rapid component of the delayed rectifier K current, IKr, which plays a critical role in cardiac repolarization.

Objectives: While the complete form of trisomy 22 is seemingly incompatible with life, the mosaic form is a rare syndrome associated with developmental delays, intellectual disability, and dysmorphic features. Due in part to the difficulty of analyzing chromosomal mosaicism, many instances either go undiagnosed or have their diagnosis delayed. We report a case of mosaic trisomy 22 in a diamnionic-dichorionic twin with marked growth discordance and intra-uterine growth restriction, diagnosed in a 2-year-old with developmental delays, sensorineural hearing loss, cardiac and gastrointestinal abnormalities, and osteopenia of prematurity.
