Paroxysmal Sympathetic Hyperactivity.

Paroxysmal sympathetic hyperactivity (PSH) is a relatively common, but often unrecognized, complication of acute diffuse or multifocal brain diseases, most frequently encountered in young comatose patients with severe traumatic brain injury. It is presumed to be caused by loss of cortical inhibitory modulation of diencephalic and brain stem centers and possible additional maladaptive changes in the spinal cord that combine to produce exaggerated sympathetic responses to stimulation. The syndrome consists of repeated sudden episodes of tachycardia, tachypnea, hypertension, sweating, and sometimes fever and dystonic posturing.

Real-world utilization of andexanet alfa.

Objective: In 2018, the FDA approved andexanet alfa for the reversal of life-threatening hemorrhages in patients anticoagulated with apixaban or rivaroxaban. Yet, cost-effective factor Xa inhibitor reversal remains controversial. The objective of this study was to describe real world utilization of andexanet alfa.

Direct Oral Anticoagulant Use After Transcatheter Aortic Valve Replacement: A Case Series.

Background: Use of an anticoagulant after transcatheter aortic valve replacement (TAVR) has been increasing in practice after noted leaflet thrombosis on dual antiplatelet therapy. As the use of anticoagulation increases so does the number of poor warfarin candidates or warfarin intolerant patients. While direct oral anticoagulant (DOAC) use is increasing for other indications, there is a paucity of data for use after TAVR.
