Predictors of Paravalvular Regurgitation After Implantation of the Fully Repositionable and Retrievable Lotus Transcatheter Aortic Valve (from the REPRISE II Trial Extended Cohort)

Paravalvular leak (PVL) after transcatheter aortic valve replacement is associated with worse long-term outcomes. The Lotus Valve incorporates an innovative Adaptive Seal designed to minimize PVL. This analysis evaluated the incidence and predictors of PVL after implantation of the Lotus transcatheter aortic valve. The REPRISE II (REpositionable Percutaneous Replacement of Stenotic Aortic Valve th

Prognostic implications of fasting plasma glucose in subjects with echocardiographic abnormalities

Aims To examine whether baseline fasting plasma glucose (FPG) modifies the prognostic role of left ventricular (LV) mass, geometric pattern, and diastolic function, for prediction of cardiovascular morbidity and mortality. Methods Population-based cohort study comprising of 1047 men and 456 women with preserved ejection fraction, included between 2002 and 2006, who underwent echocardiography based

Hip fracture; an interruption that has consequences four months after a hip fracture. A qualitative study

Background: Effects following a hip fracture often lead to functional disabilities and increased dependence on others. Although persons sustaining a hip fracture constitute a heterogeneous group in Swedish health care, they tend to be treated as a homogenous one. Aim: The aim of this study was to reveal how previously healthy people, aged 65 years and older, described how they had adapted to daily

Quantification of cartilage oligomeric matrix protein (COMP) and a COMP neoepitope in synovial fluid of patients with different joint disorders by novel automated assays

Objective: To develop automated immunoassays for the quantification of Cartilage Oligomeric Matrix Protein (COMP) and a COMP neoepitope in synovial fluid and to investigate their diagnostic potential in different joint conditions. Methods: Two sandwich immunoassays were developed for the quantification of COMP and a COMP neoepitope, using an automated analyser (IDS-iSYS, Immunodiagnostic Systems,

Results from multiple prospective single-center clinical trials of the off-the-shelf p-Branch fenestrated stent graft

Objective: The purpose of this study was to report prospective data of an off-the-shelf fenestrated endograft (Zenith p-Branch; Cook Medical, Bloomington, Ind) from four centers for the treatment of patients with pararenal abdominal aortic aneurysms. Methods: Data were combined from four single-center investigational studies conducted in the United States and Europe. The p-Branch endograft consist

Substance P represents a novel first-line defense mechanism in the nose

Background: Neuropeptides, such as substance P (SP), have long been seen as mediators of widespread continuous airway inflammation, a process known as neurogenic inflammation. However, this has been difficult to demonstrate clinically, suggesting an alternative role for these signaling molecules. Objectives: We sought to examine the role of SP in nasal infection by assessing the release of SP in r

Objective. To carry out a literature review on the use of elastography in obstetrics to investigate the capabilities of this technique for uterine scar evaluation. Material and methods. A systematic review of the literature published in 2011 to 2016 was carried out searching with the use of key words. Results. Among 25 publications dealing with elastography used in obstetric and gynecologic practi

Transplantation of mesenchymal stem cells : A future therapy for Parkinson's disease?

Parkinson's disease (PD) is a common, progressive neurodegenerative disorder associated with a loss of dopaminergic cells in the substantia nigra pars compacta and a lack of dopamine in the striatum. To halt or reverse this disease, neurorestorative approaches or neuroprotective treatments are urgently needed. Recently, the first clinical trials transplanting mesenchymal stem cells (MSCs) have bee

Accurate prediction of X-ray pulse properties from a free-electron laser using machine learning

Free-electron lasers providing ultra-short high-brightness pulses of X-ray radiation have great potential for a wide impact on science, and are a critical element for unravelling the structural dynamics of matter. To fully harness this potential, we must accurately know the X-ray properties: intensity, spectrum and temporal profile. Owing to the inherent fluctuations in free-electron lasers, this

Mathematical modeling of the protein corona : Implications for nanoparticulate delivery systems

This article discusses the role of the protein corona in delivery systems with tagged nanoparticles and how knowledge of the protein corona can help in optimizing delivery. The basic question is whether and how the binding of proteins and other biomolecules at the nanoparticle surface interfere with the interaction between a tag and its receptor. This is an interesting problem in many respects, bu

Search for new phenomena in final states with large jet multiplicities and missing transverse momentum with ATLAS using √s=13 TeV proton-proton collisions

Results are reported of a search for new phenomena, such as supersymmetric particle production, that could be observed in high-energy proton-proton collisions. Events with large numbers of jets, together with missing transverse momentum from unobserved particles, are selected. The data analysed were recorded by the ATLAS experiment during 2015 using the 13 TeV centre-of-mass proton-proton collisio
