Background:
and Purpose In the ESCAPE-NA1 (Efficacy and Safety of Nerinetide for the Treatment of Acute Ischaemic Stroke) trial, treatment with nerinetide was associated with improved outcomes in patients who did not receive intravenous alteplase. We compared the effect of nerinetide on clinical outcomes in patients without concurrent intravenous alteplase treatment within different patient subgroups.
Methods:
ESCAPE-NA1 was a multicenter randomized trial in which acute stroke patients with baseline Alberta Stroke Program Early CT Score (ASPECTS) >4 undergoing endovascular treatment (EVT) were randomized to intravenous nerinetide or placebo. The primary outcome was independence (modified Rankin Scale [mRS] score 0–2) at 90 days. We assessed baseline, clinical, and imaging variables as predictors of outcome and for evidence of treatment effect modification. We constructed two multivariable models using variables known prior to randomization and variables known immediately post-EVT procedure to provide adjusted estimates of effect. We assessed for evidence of treatment effect modification using multiplicative interaction terms within each model.
Results:
Four hundred forty-six patients were included in the analysis. Clinical outcomes were better in patients randomized to the nerinetide arm (mRS 0–2: 59.4% vs. 49.8%). There was possible treatment effect modification by ASPECTS score; patients with ASPECTS 8–10 showed a larger treatment effect compared to those with lower ASPECTS score. Younger age, lower NIHSS score, lower baseline serum glucose, absence of atrial fibrillation at baseline, higher ASPECTS score, middle cerebral artery (vs. internal carotid artery) occlusion, use of conscious or no sedation (vs. general anesthesia), and faster treatment were all predictors of favorable outcome.
Conclusion
Patients in the nerinetide arm who were not treated with concurrent alteplase showed improved clinical outcomes and the treatment effect was larger among patients with favorable ASPECTS profiles.

Background:
Phantom limb pain (PLP) is the most common type of pain experienced by amputees and is chronic and complex, with manifestations including pain in a limb that no longer exists. To date, treatments that are pharmaceutical or surgical in nature are relatively ineffective at bringing much relief as the pathophysiology of PLP is somewhat obscure. Chronic pain syndromes such as PLP may benefit from sympathetic nervous system modulation through the stellate ganglion.Case Ten refractory PLP patients treated with ultrasound-guided stellate ganglion pulsed radiofrequency ablation (SG PRF) after a diagnostic stellate ganglion block took effect: A case series Patients were assessed before and after the treatment at 1 week, 1 month, and 3 months. Significant reductions in pain as measured using a numerical rating scale; Pain Disability Indexwas improved, and Medication Quantification Scale also was improved. Minimal side effects.
Conclusions
Ultrasound-guided SG PRF has provided promising results for PLP by giving the patient with sustained pain relief and functional improvement without much side effects. Further studies need to be done to validate this finding.
