TL;DR: Single-reviewer abstract screening does not appear to fulfill the high methodological standards that decisionmakers expect from systematic reviews, but it may be a viable option for rapid reviews, which deliberately lower methodological standards to provide decisionmakers with accelerated evidence synthesis products.

TL;DR: A novel matrix-based implant cartilage repair composed of both fibrin and hyaluronan in a defined ratio that takes advantage of the biological and mechanical properties of these two elements.
Abstract: Fibrin, a homologous polymer, is the natural scaffold of wound healing and therefore a candidate as a carrier for cell transplantation. We explored a novel matrix-based implant cartilage repair composed of both fibrin and hyaluronan in a defined ratio that takes advantage of the biological and mechanical properties of these two elements. The matrix was seeded with autologous chondrocytes expanded in the presence of a proprietary growth factor variant designed to preserve their chondrogenic potential. We prospectively followed eight patients with symptomatic-chronic cartilage defects treated with this carrier. Patients had arthroscopy to harvest autologous chondrocytes then grown in autologous serum. Chondrocytes were cultured in the presence of the FGF variant and then seeded on the fibrin-hyaluronan matrix. About 4 weeks following biopsy, the patients underwent implantation of the constructs by miniarthrotomy. Three of the eight patients had transient effusion. Clinical performance was measured by Lysholm and IKDC scores, MRI, and the need for secondary surgery. The clinical outcome of a 1-year followup demonstrated increase of clinical scores. The MRI followup showed good filling of the defect with tissue having the imaging appearance of cartilage in all patients. Apart from the transient effusion in three patients we observed no other adverse events during the followup.

TL;DR: A simple score to estimate early mortality of ischemic stroke patients treated at a stroke unit that could help clinicians in short-term prognostication for management decisions and counseling is developed.
Abstract: Background and Purpose— Several risk factors are known to increase mid- and long-term mortality of ischemic stroke patients. Information on predictors of early stroke mortality is scarce but often ...

TL;DR: In this paper, the authors examine the origin of magnetic noise in magnetoresistive sensors and show that a topologically protected magnetic vortex state in the transducer element can be used to overcome these limitations.
Abstract: Micromagnetic sensors play a key role in a variety of industries, including the automotive industry, where they are used, for example, for speed and position detection. The adoption of emerging magnetoresistive sensor technology such as anisotropic magnetoresistance, giant magnetoresistance and tunnel magnetoresistance sensors is driven principally by their enhanced sensitivity and improved integration capabilities compared with conventional Hall effect sensors. At the heart of such sensors is a microstructured ferromagnetic thin-film element that transduces the magnetic signal, but these elements often exhibit a nonlinear hysteresis curve and the performance of the sensors is limited by magnetic noise. Here, we examine the origin of magnetic noise in magnetoresistive sensors and show that a topologically protected magnetic vortex state in the transducer element can be used to overcome these limitations. Using analytic and micromagnetic models, we find that the noise is due mainly to irreproducible magnetic switching of the transducer element at external fields that are close to the Stoner–Wohlfarth switching field. Then, using a flux-closed vortex configuration, we develop a giant magnetoresistance sensor layout that, compared to existing state-of-the-art sensors, has lower magnetic noise, a linear regime that is around an order of magnitude higher and negligible hysteresis.
