Percutaneous coronary intervention versus coronary artery bypass grafting in patients with three-vessel or left main coronary artery disease : 10-year follow-up of the multicentre randomised controlled SYNTAX trial

BACKGROUND: The Synergy between PCI with Taxus and Cardiac Surgery (SYNTAX) trial was a non-inferiority trial that compared percutaneous coronary intervention (PCI) using first-generation paclitaxel-eluting stents with coronary artery bypass grafting (CABG) in patients with de-novo three-vessel and left main coronary artery disease, and reported results up to 5 years. We now report 10-year all-cau

How does image quality affect radiologists’ perceived ability for image interpretation and lesion detection in digital mammography?

Objectives: To study how radiologists’ perceived ability to interpret digital mammography (DM) images is affected by decreases in image quality. Methods: One view from 45 DM cases (including 30 cancers) was degraded to six levels each of two acquisition-related issues (lower spatial resolution and increased quantum noise) and three post-processing-related issues (lower and higher contrast and incr

Fastighetsägare som prosumenter – stödstrukturer och hinder

Solceller har en viktig roll att fylla för att uppnå politiskt fattade mål om 100%hållbart elsystem. Det är rimligt att anta att det är i bebyggelsen som en storutbyggnad kommer att behöva ske eftersom det är existerande strukturermed nätanslutningar där det också finns möjlighet att använda den solel somproduceras. Fastighetsägare blir därmed en viktig aktörsgrupp att engagera.En relativt outfors

Prehospital administration of P2Y12 inhibitors and early coronary reperfusion in primary PCI : an observational comparative study

The newer oral P2Y12 inhibitors prasugrel and ticagrelor have been reported to be more potent and faster-acting antiplatelet agents than clopidogrel. This study aimed to investigate whether prehospital loading with prasugrel or ticagrelor improves early coronary reperfusion as compared to prehospital loading with clopidogrel in a real-world ST-elevation myocardial infarction (STEMI) setting. Over

Developmental changes in the rules for B cell selection*

The autoimmune checkpoint during B cell maturation eliminates self-antigen reactive specificities from the mature B cell repertoire. However, an exception to this rule is illustrated by B-1 cells, an innate-like self-reactive B cell subset that is positively selected into the mature B cell pool in a self-antigen-driven fashion. The mechanisms by which B-1 cells escape central tolerance have puzzle

Radial vs. femoral approach for primary percutaneous coronary intervention in octogenarians

BACKGROUND: The transradial approach is associated with fewer bleeding complications during percutaneous coronary interventions (PCIs) but is more technically challenging and associated with prolonged times during intervention. The aim of this study is to retrospectively compare the results of radial vs. femoral approach in patients >or=80 years old undergoing primary or rescue PCI.METHODS: Betwee

Pneumococcal vaccination in inflammatory rheumatic disease and in splenectomy patients. From antibody response to memory cells.

Objectives:The overall aim of the dissertation is to examine antibody response to immunization with pneumococcal vaccine in patients with inflammatory rheumatic disease (IRD), in relation to disease-modifying antirheumatic drug (DMARD) treatments, and in postsplenectomy patients.Methods:(I) Splenectomized patients without previous pneumococcal conjugate vaccine (PCV) immunization were invited to r

Object Permanence

Object permanence is the capacity to represent objects as persisting in time and space independently of perception.

Evaluating the Effects of SARS-CoV-2 Spike Mutation D614G on Transmissibility and Pathogenicity

Global dispersal and increasing frequency of the SARS-CoV-2 spike protein variant D614G are suggestive of a selective advantage but may also be due to a random founder effect. We investigate the hypothesis for positive selection of spike D614G in the United Kingdom using more than 25,000 whole genome SARS-CoV-2 sequences. Despite the availability of a large dataset, well represented by both spike

Geographical and temporal distribution of SARS-CoV-2 clades in the WHO European Region, January to June 2020

We show the distribution of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) genetic clades over time and between countries and outline potential genomic surveillance objectives. We applied three genomic nomenclature systems to all sequence data from the World Health Organization European Region available until 10 July 2020. We highlight the importance of real-time sequencing and data

Cerebrospinal fluid proteome maps detect pathogen-specific host response patterns in meningitis

Meningitis is a potentially life-threatening infection characterized by the inflammation of the leptomeningeal membranes. Many different viral and bacterial pathogens can cause meningitis, with differences in mortality rates, risk of developing neurological sequelae and treatment options. Here we constructed a compendium of digital cerebrospinal fluid (CSF) proteome maps to define pathogen-specifi
