The impact of rituximab infusion protocol on the long-term outcome in anti-MuSK myasthenia gravis
2018
ObjectiveTo evaluate whether the clinical benefit and relapse rates in anti-muscle-specific kinase (MuSK) myasthenia gravis (MG) differ depending on the protocol of rituximab followed. MethodsThis retrospective multicentre study in patients with MuSK MG compared three rituximab protocols in terms of clinical status, relapse, changes in treatment, and adverse side effects. The primary effectiveness endpoint was clinical relapse requiring a further infusion of rituximab. Survival curves were estimated using Kaplan-Meier methods and survival analyses were undertaken using Cox proportional-hazards models. ResultsTwenty-five patients were included: 11 treated with protocol 4 + 2 (375 mg/m(2)/4 w…

Reversal of rivaroxaban-induced alterations on hemostasis by different coagulation factor concentrates – in vitro studies with steady and circulating…
2015
BACKGROUND: Despite the good safety of rivaroxaban, there is limited information on strategies for urgent reversal of its antihemostatic effects.Methods and Results:Alterations of hemostasis induced by rivaroxaban (230 ng/ml) were assessed by using several tests applied to steady and circulating human blood. Effects on thrombin generation (TG) and thromboelastometry (TEM) parameters were measured. Modifications in platelet adhesive, aggregating and procoagulant activities were evaluated in studies with circulating blood. The potential reversal of prothrombin complex concentrates (PCCs; 50 IU/kg), activated PCCs (aPCCs; 75 IU/kg), or recombinant factor VIIa (rFVIIa; 270 μg/kg) was evaluated.…
Drug‐refractory myasthenia gravis: Clinical characteristics, treatments, and outcome
2022
[Objective] To describe the clinical characteristics and outcomes in patients with refractory myasthenia gravis (MG) and to determine the effectiveness and side effects of the drugs used for their treatment.
Antidoping Science
2018
The ineffectiveness of antidoping programs in elite sport, largely due to human and political factors, is leading to a new resolve and greater transparency of antidoping authorities and those stakeholders interested in drug-free sport. The perception by the public, athletes, and the World Anti-Doping Agency (WADA) of antidoping science and current drug testing programs in elite sport varies widely from "ineffective" to "robust and reliable." Here, we discuss why a careful and considered reevaluation of the underlying premise of antidoping science is needed to bring this unique application of predictive/diagnostic science more in line with other areas of medicine. We show how the validity of…
