Quantum Theory of Massless Particles in Stationary Axially Symmetric Spacetimes.

Quantum equations for massless particles of any spin are considered in stationary uncharged axially symmetric spacetimes. It is demonstrated that up to a normalization function, the angular wave function does not depend on the metric and practically is the same as in the Minkowskian case. The radial wave functions satisfy second order nonhomogeneous differential equations with three nonhomogeneous terms, which depend in a unique way on time and space curvatures.

Pomona Large Vessel Occlusion Screening Tool for Prehospital and Emergency Room Settings.

Background: Early identification of patients with acute ischemic strokes due to large vessel occlusions (LVO) is critical. We propose a simple risk score model to predict LVO.

Method: The proposed scale (Pomona Scale) ranges from 0 to 3 and includes 3 items: gaze deviation, expressive aphasia, and neglect.

Chronic cerebral hypoperfusion induced by bilateral carotid artery stenosis causes selective recognition impairment in adult mice.

Objectives: Chronic cerebral hypoperfusion (CCH) can result in vascular dementia and small vessel white matter ischemic injury. These findings have previously been demonstrated in a murine experimental model of CCH secondary to bilateral common carotid artery stenosis (BCAS). This study sought to elucidate the effects of CCH on recognition memory as assessed by the novel object recognition (NOR) test and histological analysis of the hippocampus and perirhinal cortex.

The Weekend Effect on Morbidity and Mortality Among Pediatric Epilepsy Admissions.

Background: Pediatric epilepsy is one of the most common neurological disorders with low mortality and high morbidity, often requiring hospitalization. Weekend admissions have been shown to be associated with worse outcomes compared with their weekday counterparts. To date, no study has assessed the impact of weekend admission on clinical and quality outcomes in the pediatric epilepsy population.

Potentially preventable complications in epilepsy admissions: The "weekend effect".

Introduction: Epilepsy affects approximately 1% of the population in the United States with frequent hospital admissions accounting for a significant burden on patients and society as a whole. Weekend admissions have generally been found to have poorer outcomes compared to weekday admissions with increased rates of preventable complications, such as nationally identified "hospital-acquired conditions" (HAC).

Objective: This study aimed to assess the impact of weekend admission on HACs and mortality in the adult epilepsy population.
