Multimodal Approaches for Regenerative Stroke Therapies: Combination of Granulocyte Colony-Stimulating Factor with Bone Marrow Mesenchymal Stem Cells is Not Superior to G-CSF Alone.

Attractive therapeutic strategies to enhance post-stroke recovery of aged brains include methods of cellular therapy that can enhance the endogenous restorative mechanisms of the injured brain. Since stroke afflicts mostly the elderly, it is highly desirable to test the efficacy of cell therapy in the microenvironment of aged brains that is generally refractory to regeneration. In particular, stem cells from the bone marrow allow an autologous transplantation approach that can be translated in the near future to the clinical practice.

Do nasogastric tubes worsen dysphagia in patients with acute stroke?

Background: Early feeding via a nasogastric tube (NGT) is recommended as safe way of supplying nutrition in patients with acute dysphagic stroke. However, preliminary evidence suggests that NGTs themselves may interfere with swallowing physiology. In the present study we therefore investigated the impact of NGTs on swallowing function in acute stroke patients.

Serum procalcitonin in cerebral ventriculitis.

Objectives: The objective of this study was to test the hypothesis that serum procalcitonin is increased in patients with bacterial cerebral ventricular infections after the insertion of temporary external ventricular drains.

Patients And Methods: This open, prospective study included patients requiring temporary external ventricular drains for various neurologic conditions such as intracerebral hemorrhage with ventricular hemorrhage or space-occupying lesions in the posterior fossa (cerebellar infarctions or hemorrhages). Patients experiencing primary central nervous system infection or sepsis were excluded.
