Dynamic Functional Connectivity States Between the Dorsal and Ventral Sensorimotor Networks Revealed by Dynamic Conditional Correlation Analysis of Resting-State Functional Magnetic Resonance Imaging.

Functional connectivity in resting-state functional magnetic resonance imaging (rs-fMRI) has received substantial attention since the initial findings of Biswal et al. Traditional network correlation metrics assume that the functional connectivity in the brain remains stationary over time. However, recent studies have shown that robust temporal fluctuations of functional connectivity among as well as within functional networks exist, challenging this assumption.

Antiphospholipid antibodies and lower extremity peripheral arterial disease - a systematic review and meta-analysis.

Background: Despite being an important risk factor for venous thromboembolism and ischaemic stroke, the role of antiphospholipid antibodies in patients with peripheral arterial disease remains a matter of debate. The aim of this study was to evaluate the association of persistently elevated antiphospholipid antibodies and lower extremity peripheral arterial disease.

Methods: We conducted a systematic review of electronic databases including MEDLINE, EUROPUBMED and EMBASE to assess the prevalence of antiphospholipid antibodies in patients with lower extremity peripheral arterial disease.

Direct oral factor Xa inhibitors for the prevention of non-central nervous systemic embolism patients with non-valvular atrial fibrillation - a systematic review and meta-analysis.

Background: The aim of this systematic review and meta-analysis was to evaluate the efficacy of direct oral factor Xa inhibitors for preventing non-central nervous systemic embolism in patients with non-valvular atrial fibrillation.

Methods: We conducted a systematic review of the following databases: Ovid MEDLINE, EUROPUBMED, EMBASE, and the Cochrane Central Register of Controlled Trials, from July 1st 1990 to April 1st, 2015. Randomised controlled trials were included if they reported the outcomes of patients with non-valvular atrial fibrillation treated with a direct oral factor Xa inhibitors compared to a vitamin K antagonist.
