Stroke in pregnant women has a mortality rate of 1.4 deaths per 100,000 deliveries. Vascular malformations are the most common cause of hemorrhagic stroke in this population; preeclampsia and other risk factors have been identified. However, nearly a quarter of strokes have an undeterminable cause. ⋯ The most common maternal outcome was death (48.8%), and fetal outcomes were evenly distributed among term delivery, preterm delivery, and fetal or neonatal death. Spontaneous ICH carries a high maternal mortality with IPH being the most common type, most frequently presenting in the third trimester. Diagnosis and management do not differ for the parturient compared to the non-pregnant woman.

To investigate the effects of hyperbaric oxygen (HBO) on brain damage and autophagy levels in a rat model of middle cerebral artery occlusion. ⋯ Cerebral ischemia caused early neuronal death due to necrosis, followed by delayed neuronal death due to apoptosis. Consequently, autophagy might be involved in all processes of ischemia. HBO could protect the brain against ischemic injury, and the possible mechanisms might be correlated with decreased autophagy activity and decreased apoptosis and necrosis levels.

Multicenter Study
Enteral Nutrition Initiation in Children Admitted to Pediatric Intensive Care Units After Traumatic Brain Injury.
Traumatic brain injury (TBI) is the leading cause of death and long-term disability among injured children. Early feeding has been shown to improve outcomes in adults, with some similar evidence in children with severe TBI. We aimed to examine the current practice of initiation of enteral nutrition in children with TBI and to evaluate the risk factors associated with delayed initiation of enteral nutrition. ⋯ Children with severe TBI and higher ISS were more likely to have delayed initiation of enteral nutrition. Delayed enteral nutrition was an independent risk factor for worse functional status at ICU discharge for the entire cohort, but not for the severe TBI group.
