BACKGROUND Transcatheter aortic valve implantation (TAVI) is associated with a higher risk of neurological events for both the transfemoral and transapical approach than surgical valve replacement. Cerebral magnetic resonance imaging has revealed more new, albeit clinically silent lesions from procedural embolization, yet the main source and predominant(More)
Serum levels of soluble CD14 were elevated in HIV-infected asymptomatic patients or those with lymphadenopathy (CDC II/III) 2.9 +/- 0.8 mg/l compared with normal controls with 2.2 +/- 0.47 mg/l, P < 0.001. A further rise was seen in patients with ARC (CDC IVA) 3.8 +/- 1.1 mg/l, P < 0.01 and patients with AIDS (CDC IVB-D) 5.7 +/- 2.5 mg/l, P < 0.01. Although(More)
CD4(+) T (helper) cells migrate in huge numbers through lymphoid organs. However, little is known about traffic routes and kinetics of CD4(+) T-cell subsets within different organ compartments. Such information is important because there are indications that CD4(+) T cells may influence the function of microenvironments depending on their developmental(More)
The incidence of bleeding and thrombo-embolic complications in patients undergoing mechanical circulatory support therapy remains high and is associated with bad outcomes and increased costs. The need for anticoagulation and anti-platelet therapy varies widely between different pulsatile and non-pulsatile ventricular-assist devices (VADs) and extracorporeal(More)
OBJECTIVE This report suggests that impedance aggregometry can be helpful to assess optimum time for and minimize the risk of catheter removal during double antiplatelet therapy. CASE REPORT A 52-year-old patient undergoing cystectomy during combined general and epidural anesthesia suffered an acute myocardial infarction, and required coronary artery(More)
The relationship between lytic state variables and ex vivo clot lysability was investigated in blood drawn from patients during streptokinase administration for acute myocardial infarction. A lytic state was already evident after 5 min of treatment and after 20 min the plasminogen concentration had decreased to 24%, antiplasmin to 7% and fibrinogen 0.2 g/l.(More)
AIMS Cardiac overexpression of the beta-adrenoceptor-coupled G-protein subunit Galphas in mice enhances inotropic responses to sympathetic stimulation, but evokes cardiomyopathy with increasing age. We tested whether functional single nucleotide polymorphisms (SNPs) in the human Galphas (GNAS) gene modulate Galphas expression and assessed functional(More)
Transcatheter aortic valve implantation (TAVI) is a novel treatment option for patients with severe, symptomatic aortic valve stenosis considered inoperable or at high risk for surgical aortic valve replacement. Despite rapid adoption of this technology into clinical application, however, recent randomized controlled clinical trials have raised safety(More)
BACKGROUND Interscalene brachial plexus (ISB) block is often associated with phrenic nerve block and diaphragmatic paresis. The goal of our study was to test if the anterior or the posterior ultrasound guided approach of the ISB is associated with a lower incidence of phrenic nerve blocks and impaired lung function. METHODS This was a prospective,(More)
