Our primary objective was to determine the proportion of the population able to achieve acute cerebrovascular care in emergency stroke systems (ACCESS) in the United States. In addition, we examined how policy changes, including allowing ground ambulances to cross state lines and allowing air ambulances to transport patients from the prehospital setting to primary stroke centers (PSCs), would affect population access to stroke care. ⋯ About half of the US population has timely access to a PSC. The use of air ambulances to triage patients with ischemic stroke to a PSC would increase the percentage of the US population with prompt access to stroke care. These data have implications for the ongoing design of the US stroke system.

Safety and immunological effects of mesenchymal stem cell transplantation in patients with multiple sclerosis and amyotrophic lateral sclerosis.
To evaluate the feasibility, safety, and immunological effects of intrathecal and intravenous administration of autologous mesenchymal stem cells (MSCs) (also called mesenchymal stromal cells) in patients with multiple sclerosis (MS) and amyotrophic lateral sclerosis (ALS). ⋯ Transplantation of MSCs in patients with MS and ALS is a clinically feasible and relatively safe procedure and induces immediate immunomodulatory effects. Trial Registration clinicaltrials.gov Identifier: NCT00781872.

Case ReportsIsolated distal myopathy of the upper limbs associated with mitochondrial DNA depletion and polymerase gamma mutations.
To describe an unusual clinical phenotype in an adult harboring 2 compound heterozygous polymerase γ (POLG) mutations. ⋯ Our case broadens the phenotypic spectrum of disorders associated with POLG mutations and highlights the complex relationship between genotype and phenotype in POLG-related disease.

Randomized Controlled TrialA randomized controlled double-masked trial of albuterol add-on therapy in patients with multiple sclerosis.
Interleukin 12 (IL-12), a cytokine that promotes generation of helper T cells subtype 1, is increased in multiple sclerosis. Albuterol sulfate, a β2-adrenergic agonist, reduces IL-12 expression, so we tested the effect of albuterol as an add-on treatment to glatiramer acetate therapy. ⋯ Treatment with glatiramer acetate plus albuterol is well tolerated and improves clinical outcomes in patients with multiple sclerosis.
