Investigating the Impact of Global Positioning System Evidence

The continued amalgamation of Global Positioning Systems (GPS) into everyday activities stimulates the idea that these devices will increasingly contribute evidential importance in digital forensics cases. This study investigates the extent to which GPS devices are being used in criminal and civil court cases in the United Kingdom through the inspection of Lexis Nexis, Westlaw, and the British and Irish Legal Information Institute (BAILII) legal databases. The research identified 83 cases which involved GPS evidence from within the United Kingdom and Europe for the time period from 01 June 1993 to 01 June 2013. The initial empirical analysis indicates that GPS evidence in court cases is rising over time and the majority of those court cases are criminal cases.Comment: This article was published at: http://www.hicss.hawaii.edu/hicss_48/apahome48.ht

SL(5) duality from canonical M2-brane

We show how the SL(5) duality in M-theory is explained from a canonical analysis of M2-brane mechanics. Diffeomorphism constraints for a M2-brane coupled to supergravity background in d=4 are reformulated in a SL(5) covariant form, in which spatial diffeomorphism constraints are recast into a SL(5) vector and the generalized metric in the Hamiltonian constraint is quartic in the SL(5) generalized vielbein. The Hamiltonian for a M2 brane has the SL(5) duality symmetry in a background dependent gauge.Comment: 13 pages; v2: comments and references added; v3: a reference corrected, version to appear on JHE

Ixekizumab for patients with non-radiographic axial spondyloarthritis (COAST-X): a randomised, placebo-controlled trial

Background: Ixekizumab, a high-affinity interleukin-17A (IL-17A) monoclonal antibody, has previously shown efficacy in radiographic axial spondyloarthritis (also known as ankylosing spondylitis). We aimed to evaluate the efficacy and safety of ixekizumab, an IL-17 inhibitor, in non-radiographic axial spondyloarthritis. Here, we report the primary results of COAST-X. Methods: COAST-X was a 52-week, randomised, double-blind, placebo-controlled, parallel-group study done at 107 sites in 15 countries in Europe, Asia, North America, and South America. Eligible participants were adults (aged ≥18 years) with active axial spondyloarthritis without definite radiographic sacroiliitis (non-radiographic axial spondyloarthritis), objective signs of inflammation (via MRI or C-reactive protein), and an inadequate response or intolerance to non-steroidal anti-inflammatory drugs (NSAIDs). Patients were randomly assigned (1:1:1) to receive subcutaneous 80 mg ixekizumab every 4 weeks (Q4W) or every 2 weeks (Q2W), or placebo. Changing background medications or switching to open-label ixekizumab Q2W, or both, was allowed after week 16 at investigator discretion. Primary endpoints were Assessment of SpondyloArthritis international Society-40 (ASAS40) response (defined as an improvement of 40% or more and an absolute improvement from baseline of 2 units or more [range 0–10] in at least three of the four domains [patient global, spinal pain, function, and inflammation] without any worsening in the remaining one domain) at weeks 16 and 52. Patients who switched to open-label ixekizumab were imputed as non-responders in logistic regression analysis. This trial is registered with ClinicalTrials.gov, number NCT02757352. Findings: Between Aug 2, 2016, and Jan 29, 2018, 303 patients were enrolled (105 to placebo, 96 to ixekizumab Q4W, and 102 to ixekizumab Q2W). Both primary endpoints were met: ASAS40 at week 16 (ixekizumab Q4W: 34 [35%] of 96, p=0·0094 vs placebo; ixekizumab Q2W: 41 [40%] of 102, p=0·0016; placebo: 20 [19%] of 105) and ASAS40 at week 52 (ixekizumab Q4W: 29 [30%] of 96, p=0·0045; ixekizumab Q2W: 32 [31%] of 102, p=0·0037; placebo: 14 [13%] of 105). 60 (57%) of 104 patients in the placebo group, 63 (66%) of 96 in the ixekizumab Q4W group, and 79 (77%) of 102 in the ixekizumab Q2W group had at least one treatment-emergent adverse event. The most common treatment-emergent adverse events in the ixekizumab groups were nasopharyngitis and injection site reaction. Of the treatment-emergent adverse events of special interest, there was one case of serious infection in the ixekizumab Q4W group. The frequency of serious adverse events was low (four [1%] of 302) and similar across the three groups. There were no malignancies or deaths. No new safety signals were identified. Interpretation: Ixekizumab was superior to placebo for improving signs and symptoms in patients with non-radiographic axial spondyloarthritis at weeks 16 and 52. Reports of adverse events were similar to those of previous ixekizumab studies. Ixekizumab offers a potential therapeutic option for patients with non-radiographic axial spondyloarthritis who had an inadequate response or were intolerant to NSAID therapy.

Outcomes in Newly Diagnosed Atrial Fibrillation and History of Acute Coronary Syndromes: Insights from GARFIELD-AF

BACKGROUND: Many patients with atrial fibrillation have concomitant coronary artery disease with or without acute coronary syndromes and are in need of additional antithrombotic therapy. There are few data on the long-term clinical outcome of atrial fibrillation patients with a history of acute coronary syndrome. This is a 2-year study of atrial fibrillation patients with or without a history of acute coronary syndromes
