Abstract

Accurate identification of patients who will achieve a favorable outcome is almost impossible preoperatively or postoperatively in poor-grade (Hunt and Hess Grade IV and V) aneurysmal subarachnoid hemorrhage (SAH). Whether characteristics of blood pressure profiles during the first 24 hours after endovascular coiling could predict prognosis in poor grade patients was explored. Data were obtained retrospectively on all patients undergoing endovascular treatment with poor-grade SAH from November 2011 to June 2016. Blood pressure during the initial 24 hours was measured at 2-hour intervals after coil embolization. Studied features of mean systolic blood pressure (MSBP) and systolic blood pressure variability (SBPV) as well as demographics, medical history, clinical characteristics, and neurologic outcomes were documented. SBPV was determined as standard deviation and successive variation of systolic blood pressure. Logistic regression analysis was used to identify predictors of favorable outcome assessed on modified Rankin Scale score of 0 to 2. The patients with favorable and unfavorable outcome were comparable with respect to systolic blood pressure on admission and MSBP after coiling. However, MSBP between 120 and 140 mm Hg was...Continue Reading

Cajal Bodies & Gems

Cajal bodies or coiled bodies are dense foci of coilin protein. Gemini of Cajal bodies, or gems, are microscopically similar to Cajal bodies. It is believed that Cajal bodies play important roles in RNA processing while gems assist the Cajal bodies. Find the latest research on Cajal bodies and gems here.
