BACKGROUND Recent studies suggest that high-dose MgSO4 therapy is safe and reduces the incidence of DIND and subsequent poor outcome after SAH. We intended to assess the safety and efficacy of high-dose MgSO4 therapy after SAH as means to prevent DIND and to evaluate the impact on clinical outcome. METHODS This was a prospective, randomized, single-blind, placebo-controlled study. The MgSO4 i...

OBJECTIVE To investigate whether oral fluoroquinolone use is associated with an increased risk of aortic aneurysm or dissection. DESIGN Nationwide historical cohort study using linked register data on patient characteristics, filled prescriptions, and cases of aortic aneurysm or dissection. SETTING Sweden, July 2006 to December 2013. PARTICIPANTS 360 088 treatment episodes of fluoroquinol...

We define the entropy function S(p) = lim.-~zn -zln N(n ,p), where N(n ,p) is the number of different partial order relations definable over a set of n distinct objects, such that of the possible n ( n I )/2 pairs of objects, a fraction p are comparable. Using rigorous upper and lower bounds for S(p), we show that there exist real numbers p1 and p2; .083 < p1 ~ 1/4 and 3/8 ~ p2 < 48/49; such th...

We analyse the M-theoretic generalisation of the tangent space structure group after reduction of the D = 11 supergravity theory to two space-time dimensions in the context of hidden Kac–Moody symmetries. The action of the resulting infinitedimensional ‘R symmetry’ group K(E9) on certain unfaithful, finite-dimensional spinor representations inherited from K(E10) is studied. We explain in detail...

Personal wearable devices capable of recording a single lead ECG have been found to be very useful in detecting arrhythmias with and without symptoms. To describe case from Apple watch (AW) that nearly implantable cardioverter defibrillator (ICD) implant N/A A 36-year-old female long history palpitations episodes sudden onset rapid regular tachycardia associated lightheadedness, presyncope are ...
