In this article, we study a susceptible–infected–recovered (SIR) epidemic model on a network of n interacting subpopulations. We analyze the transient and asymptotic behavior of the infection dynamics in each node of the network. In contrast to the classical scalar epidemic SIR model, where the infection curve is known to be unimodal (either always decreasing over time, or initially increasing unt
A few large fires in Lithium-ion battery systems are known to have been caused by leaking coolant, and experience from fire testing indicate that coolant can be the origin of violent fires triggered before the onset of thermal runaway in the battery. It is here hypothesized that the common coolants water and ethylene glycol can form flammable gases via electrolysis in the electrical environment fo
General studies of medieval logic tend to neglect the context in which medieval logic developed and the needs to which such a development responded. Accordingly, they normally neglect the non-formal elements they encounter instead of integrating them as elements that meet the specific needs of the medieval intellectual endeavour and that are, then, part and parcel of medieval interpretations of Ar
Background: To determine if an alternating regimen of the tyrosine kinase inhibitors imatinib and regorafenib improved outcomes in patients with advanced gastrointestinal stromal tumors. Methods: ALTGIST (NCT02365441) was a randomized phase II study of standard treatment of imatinib (Arm A) compared with an experimental alternating regimen of imatinib and regorafenib (Arm B). Primary outcome was b
Background: With the provision of home infusion therapy in children with acute or long-term illness on the rise, eHealth technologies have the potential to bridge the transition between hospital and home. However, eHealth interventions intended to support parents in managing home infusion therapy are sparse. Gaining insight into the needs and experiences of parents and health care professionals is
Treatment with warfarin in combination with clopidogrel has been shown to reduce the incidence of major bleeding as compared to triple antithrombotic therapy (TT; warfarin, clopidogrel and aspirin). However, there are uncertainties regarding the risk for thrombosis since poor-responsiveness to clopidogrel is common. Ticagrelor is a more potent platelet inhibitor, but data supporting concurrent use
OBJECTIVES: We assessed pharmacodynamic (PD) response for the reduced prasugrel 5-mg maintenance dose in very elderly (≥75y; VE) patients. BACKGROUND: In TRITON-TIMI 38, prasugrel 10-mg reduced ischemic events versus clopidogrel 75-mg, but increased bleeding in VE patients. METHODS: We examined PD and active-metabolite pharmacokinetics with prasugrel 5-mg and 10-mg and clopidogrel 75-mg in a three
OBJECTIVES: The aim of this study was to confirm prior modeling data suggesting that prasugrel 5 mg in low-body-weight (LBW) patients would be noninferior to prasugrel 10 mg in higher-body-weight (HBW) patients as assessed by maximal platelet aggregation (MPA). BACKGROUND: Prasugrel 10 mg reduced ischemic events compared with clopidogrel 75 mg but increased bleeding, particularly in LBW patients.
Body weight is a predictor of clopidogrel response. However, no prospective studies have compared pharmacodynamic (PD) and pharmacokinetic (PK) data based on body weight. We compared PD and PK effects of clopidogrel 75 mg in low body weight (LBW, <60 kg) and higher body weight (HBW, ≥60 kg) patients with stable coronary artery disease. LBW (n = 34, 56.4 ± 3.7 kg) and HBW (n = 38, 84.7 ± 14.9 kg) a
We compared results obtained with the Nanosphere Verigene® System, a novel point-of-care (POC) genetic test capable of analysing 11 CYP2C19 variants within 3 hours, to an established, validated genotyping method (Affymetrix™ DMET+; reference assay) for identifying extensive and reduced metabolisers of clopidogrel. Based on genotyping, patients (N=82) with stable coronary artery disease on clopidog
INTRODUCTION. Prolonged cardiopulmonary resuscitation (CPR) with manual chest compressions (CC) during simultaneous percutaneous coronary intervention (PCI) is exceedingly difficult, with high mortality rates. The use of a mechanical CC (MCC) device can overcome the ordeal of manual CC. The aims of this thesis were to investigate the impact of the introduction of the LUCAS™ MCC device in the cath-
Background: In current guidelines, prolonged cardiopulmonary resuscitation (CPR) mandates administration of repeated intravenous epinephrine (EPI) doses. This porcine study simulating a prolonged CPR-situation in the coronary catheterisation laboratory, explores the effect of EPI-administrations on coronary perfusion pressure (CPP), continuous coronary artery flow average peak velocity (APV) and a
Resuscitation after cardiac arrest (CA) in the catheterization laboratory (cath-lab) using mechanical chest compressions (CC) during simultaneous percutaneous coronary intervention (PCI) is a strong recommendation in the 2015 European Resuscitation Council (ERC) guidelines. This study aimed at re-evaluating survival to hospital discharge and assess long term outcome in this patient population.
This porcine study was designed to explore the effects of repetitive intravenous adrenaline doses on physiologic parameters during CPR.
PURPOSE: Lengthy resuscitations in the catheterisation laboratory carry extremely high rates of mortality because it is essentially impossible to perform effective chest compressions during percutaneous coronary intervention (PCI). The purpose of this study was to evaluate the use of a mechanical chest compression device, LUCAS, in the catheterisation laboratory, in patients who suffered circulato
Platelet P-selectin and activated glycoprotein IIb–IIIa (GPIIb–IIIa) are markers of platelet activation and mediates platelet aggregation. Prasugrel (Pras) 5 mg may be used in very elderly (VE) acute coronary syndrome (ACS) patients undergoing PCI, but its effect on platelet P-selectin and activated GPIIb–IIIa in those patients is not known. Stable ACS patients, VE (78 ± 5 years, n = 23) and non-e
