Background Biatrial, extensive, and complex ablation strategies have been published for the treatment of neurally mediated syncope, sinus node dysfunction, functional atrioventricular block. We developed a less extensive more specific approach compared with previously cardioneuroablation strategies, called cardio-neuromodulation. It is based on tailored vagolysis sinoatrial through partial anterior right-ganglionated plexus, preferentially right-sided approach. Methods Patients syncope were...

Abstract Background Atabecestat, a potent brain-penetrable inhibitor of BACE1 activity that reduces CSF amyloid beta (Aβ), was developed for oral treatment Alzheimer’s disease (AD). The long-term safety and effect atabecestat on cognitive performance in participants with predementia AD two phase 2 studies were assessed.

Impaired muscle activation may predispose subjects to develop chronic ankle instability. It has been suggested that impairments are found not only in structures around the injured but also more proximal joint complexes.Subjects with instability were expected show later onset times for lower limb and trunk when compared control subjects. They less variability patterns group.Controlled laboratory study.Thirty 10 participated study. The of activity 14 muscles was measured during transition from...

Abstract Freezing of gait (FOG) is an incapacitating problem in Parkinson's disease that difficult to manage therapeutically. We tested the hypothesis impaired rhythm and amplitude control a common mechanism freezing which also present during other rhythmic tasks. Therefore, we compared occurrence spatiotemporal profiles episodes upper limb motion, lower FOG. Eleven freezers, 12 non‐freezers, 11 controls performed bilateral finger movement task.

Background Unilateral diaphragm dysfunction (UDD) is an underdiagnosed cause of dyspnoea. Inspiratory muscle training (IMT) the only conservative treatment for UDD, but mechanisms improvement are unknown. We characterised effects IMT on dyspnoea, exercise tolerance and respiratory function in people with UDD. Methods 15 UDD (73% male, 61±8 years) were randomised to 6 months (50% maximal inspiratory mouth pressure ( P I,max ), n=10) or sham (10% , n=5) (30 breaths twice per day). was...

Increases in serum prolactin concentrations after administration of risperidone have been attributed, by some, to the availability paliperidone plasma. This double-blind, randomized, parallel-group study patients with schizophrenia compared following extended-release and immediate-release tablets. At steady state, doses administered resulted a similar exposure pharmacologically active fraction (i.e. + paliperidone), respectively.

Paliperidone extended‐release tablet (paliperidone ER) is a centrally active dopamine D 2 ‐ and serotonergic 5‐HT 2A ‐receptor antagonist that registered for the treatment of schizophrenia. The controlled rate release paliperidone from ER formulation designed to have slower absorption rate, which results in gradual ascending plasma concentrations with observed maximum occurring at 24 hours after dosing on first day. On subsequent days, provides minimal fluctuations concentrations. eliminated...
