Continuous-flow left ventricular assist devices (LVADs) are increasingly implanted to support patients with end-stage heart failure. These patients are at high risk for complications, many of which necessitate emergency care. While rehospitalization rates have been described, there is little data regarding emergency department (ED) visits. We hypothesize that ED visits are frequent and often requi
Introduction: In healthy carriers of the T allele of the transcription factor 7-like 2 (TCF7L2), fasting plasma glucagon concentrations are lower compared with those with the C allele. We hypothesised that presence of the T allele is associated with a diminished glucagon response during hypoglycaemia and a higher frequency of severe hypoglycaemia (SH) in type 1 diabetes (T1DM). Material and method
Hypothesis Chitosan and sulfated oat β-glucan are materials suitable to create a prebiotic coating for targeted delivery to gastrointestinal system, using the layer by layer technology. Experiment Quartz crystal microbalance with dissipation (QCM-D), spectroscopic ellipsometry (SE) and atomic force microscopy (AFM) were used to assess the multilayer formation capacity and characterize the resultin
Deep neural network architectures have recently produced excellent results in a variety of areas in artificial intelligence and visual recognition, well surpassing traditional shallow architectures trained using hand-designed features. The power of deep networks stems both from their ability to perform local computations followed by pointwise non-linearities over increasingly larger receptive fiel
Background:Chemotherapy in platinum-resistant ovarian cancer (PROC) aims for palliation and prolonging of progression-free survival (PFS). This study compares Health-related Quality of Life (HRQoL) and efficacy between single-agent chemotherapy and tamoxifen in PROC.Methods:Patients with PROC were randomised (2: 1) to chemotherapy (weekly paclitaxel 80 mg m -2 or four weekly pegylated liposomal do
Despite improved treatment results of childhood acute lymphoblastic leukemia (ALL), 20% to 30% have a relapse, and then the outcome is very poor. We studied 40 children with ALL marrow relapse piloting an ALL relapse protocol with well-known drugs and drug combinations by using a concept of response-guided design. We also measured response in logarithmic fashion. Our primary end points were achiev
OBJECTIVE: To explore the long-term benefits of shortened constraint-induced movement therapy (CIMT) in the subacute phase poststroke. DESIGN: A 1-year follow-up after shortened CIMT (3h training/d for 2 wk) where the participants had been randomized to a mitt group or a nonmitt group. SETTING: A university hospital rehabilitation department. PARTICIPANTS: Poststroke patients (N=20, 15 men, 5 wome
ObjectivesTo assess the in vitro antibiotic susceptibility of Enterococcus faecalis in biofilms.MethodsE. faecalis isolates were from infections of prosthetic hip and knee joints. Minimal biofilm eradication concentrations (MBECs) for ampicillin, vancomycin, linezolid, ciprofloxacin and rifampicin, alone and in combinations, were determined. E. faecalis biofilms in microtitre plate wells or on bea
In this study the capacity of towed floating electrical imaging for mapping a known aquifer recharge zone in more detail is investigated. A 50 km reach of the Namoi River, Australia, was surveyed. The river is perched up to 16 m above an unconfined aquifer that extends to 30 m below the ground surface. The unconfined aquifer overlies a semi-confined aquifer system. The electrical array consists of

This study investigates how organizations make sense of machine-generated digital trace data, focusing on the interpretation of LUCAS device telemetry at Jolife. While such data is highly granular, it lacks contextual information, creating challenges in translating technical outputs into meaningful representations of real-world use. Adopting a mixed-methods approach, the study combines qualitative
Wearable devices increasingly issue algorithmic verdicts on the body's recovery and readi-ness claims that may contradict what an athlete directly feels. This study examines how ama-teur endurance athletes make sense of the embodied rupture: the moment at which a weara-ble's recovery assessment conflicts with their own somatic knowledge. While Information Systems research has theorised how
We investigate the temperature-dependent resistive switching behavior of single-layer ITO/HfO₂/TiN resistive random access memory devices down to 10K. Devices formed at room temperature exhibit abrupt, Joule-heating-assisted RESET transitions that evolve into gradual, field-driven processes upon cooling. We found that the RESET voltage increases steadily with decreasing temperature, while the memo
Sensor degradation poses a significant challenge in autonomous driving. During heavy rainfall, interference from raindrops can adversely affect the quality of LiDAR point clouds, resulting in, for instance, inaccurate point measurements. This, in turn, can potentially lead to safety concerns if autonomous driving systems are not weather-aware, i.e., if they are unable to discern such changes. In t
The ALICE Collaboration at the LHC reports measurement of the inclusive production cross section of electrons from semi-leptonic decays of beauty hadrons with rapidity |y| < 0.8 and transverse momentum 1 < p(T)< 10 GeV/c, in pp collisions at root s = 2.76 TeV. Electrons not originating from semi-electronic decay of beauty hadrons are suppressed using the impact parameter of the corresponding track
Long-term instability in multiplanet exosystems is a crucial consideration when confirming putative candidates, analysing exoplanet populations, constraining the age of exosystems and identifying the sources of white dwarf pollution. Two planets that are Hill stable are separated by a wide-enough distance to ensure that they will never collide. However, Hill-stable planetary systems may eventually
We investigate the effects of fracture- and inclusion-induced seismic anisotropy in a carbonate reservoir rock and the resulting influence this anisotropy may have on surface seismic data. Whole-core velocity measurements made on a carbonate sample from the Gulf of Mexico show evidence of elastic anisotropy. Constraints on the style of this anisotropy are obtained from comparisons with effective m
BACKGROUND: Oxidative stress and related DNA damage in human sperm may be important for fecundity and pregnancy outcome. METHODS: We studied the level of oxidative DNA damage in terms of 7-hydro-8-oxo-2'-deoxyguanosine (8-oxodG) in sperm DNA among 225 first-pregnancy planners. Over the six menstrual cycle follow-up time, after cessation of contraception, 135 pregnancies were conceived. RESULTS: Th
In patients with intermediate or high grade non-Hodgkin lymphoma (NHL), third generation chemotherapy regimens have been introduced to improve survival in comparison with the standard CHOP regimen. However, most studies have found no difference between these two treatments. We conducted a meta-analysis to assess the effectiveness of third generation regimens as compared with CHOP. Our study includ
