Legal Exposure if EMS Are Noncompliant with Stroke Guidelines
If clinicians miss a stroke diagnosis or delay care for that condition, plaintiff attorneys are going to scrutinize everything ED providers could have done differently. However, whatever problems there are or were all could have started well before the patient arrived at the facility. In fact, most patients receive prehospital stroke care from EMS that is noncompliant with American Stroke Association guidelines.

Patterns of Weakness in Amyotrophic Lateral Sclerosis
Unusual patterns of weakness in the various motor neuron disorders may point to a specific diagnosis of amyotrophic lateral sclerosis, if supported by electrophysiological evidence of chronic denervation.

The Natural History of Leigh Syndrome
The natural history of Leigh syndrome is characterized by quantifiable disease progression in fewer than three years, with the poorest outcomes predicted by surfeit locus protein 1 (SURF1) pathogenic variants, bilateral caudate involvement on magnetic resonance imaging, and rapid increases in yearly Newcastle Paediatric Mitochondrial Disease Scale scores.

Rituximab Treatment for AChR Myasthenia Gravis: Results of the BeatMG Study
The B-Cell Targeted Treatment In Myasthenia Gravis (BeatMG) study was the first prospective, randomized, double-blind, placebo-controlled clinical trial to explore the role of targeted B-cell depletion in myasthenia patients. Although rituximab was found to be safe and well-tolerated, rituximab treatment did not confer a significant steroid-sparing effect compared to placebo. Results of a futility analysis suggested rituximab treatment would be unlikely to show a clinically meaningful improvement of 30% over placebo in a larger Phase III trial of mild to moderately symptomatic acetylcholine receptor autoantibody-positive generalized myasthenia gravis patients.

Plasma Biomarkers for Neurodegenerative Dementias: We Are Getting Closer
Two recent multicenter studies suggest that plasma biomarkers, including phosphorylated-tau181, could be used as cost-effective and more readily accessible biomarkers for the diagnosis and management of individuals with neurodegenerative dementias.
