Timing of Decompressive Hemicraniectomy for Stroke Clinical Sciences
Conclusions—In this nationwide analysis, early decompressive craniectomy was associated with superior outcomes. However, performing decompression before herniation may be the most important temporal consideration.

Strokes Associated With Pregnancy and Puerperium Clinical Sciences
Conclusions—The incidence of pregnancy-associated stroke in Japan did not seem higher than that in other Asian and Western countries. The proportion of hemorrhagic stroke among Japanese women was much higher than that in white women. Preexisting cerebrovascular diseases and reversible cerebral vasoconstriction syndrome play a key role in hemorrhagic and ischemic stroke, respectively.

Development and Validation of a Grading Scale for Primary Pontine Hemorrhage Clinical Sciences
Background and Purpose—We aimed to develop and validate a grading scale for predicting 30-day mortality and 90-day functional outcome in patients with primary pontine hemorrhage (PPH).Methods—We retrospectively reviewed records of consecutive patients with first-ever pontine hemorrhage from 3 teaching hospitals between 2005 and 2012. Independent factors associated with 30-day mortality were identified by logistic regression to establish a risk stratification scale, named the new PPH score. For validation of the new PPH score, we prospectively recruited subjects from 10 units between December 2014 and November 2015. The...

Missed Ischemic Stroke Diagnosis in the Emergency Department by Emergency Medicine and Neurology Services Clinical Sciences
Conclusions— Atypical symptoms associated with posterior circulation strokes lead to misdiagnoses. This was true at both an academic center and a large community hospital. Future studies need to focus on the evaluation of identification systems and tools in the emergency department to improve the accuracy of stroke diagnosis.

Use of Warfarin at Discharge Among Acute Ischemic Stroke Patients With Nonvalvular Atrial Fibrillation in China Clinical Sciences
Conclusions— The rate of warfarin use remains low among patients with ischemic stroke and known nonvalvular atrial fibrillation in China. Hospital size and academic status together with patient age, heart failure, heavy alcohol drinking, international normalized ratio in hospital, and stroke severity on admission were each independently associated with the use of warfarin at discharge. There is much room for improvement for secondary stroke prevention in nonvalvular atrial fibrillation patients in China.

Validity of Hospital Discharge Diagnosis Codes for Stroke: The Atherosclerosis Risk in Communities Study Clinical Sciences
Conclusions— A new AHA/ASA discharge code grouping to identify stroke had similar PPV and lower sensitivity compared with an alternative code grouping. Accuracy varied by patient characteristics and study sites.

Factors Associated With Length of Hospitalization in Patients Admitted With Transient Ischemic Attack in United States Clinical Sciences
Conclusions— Approximately 75% of patients admitted with transient ischemic attack stay in the hospital for ≥2 days, with the most important determinants being pre-existing medical comorbidities. Longer duration of hospital stay is associated with 2- to 5-fold greater hospitalization charges.

Seasonal Variation in 30-Day Mortality After Stroke: Teaching Versus Nonteaching Hospitals Brief Reports
Conclusions— The 30-day RAMR decreased overall, but seasonal patterns were present, with the highest RAMR in January and a smaller peak in July. Because patterns were similar for teaching and nonteaching hospitals, the July peak cannot be explained by the introduction of new trainees in the beginning of the academic year. The reasons for these seasonal patterns warrant further investigation.
