[A tool to assess functional communication skills and its correspondence with traditional language testing in patients with brain tumors].

Objective: To identify the relationship between speech impairment as measured by the Russian Aphasia Test (RAT) and functional communication as assessed by the Communicative Effectiveness Index (CETI).

Material And Methods: RAT and CETI were administered to 87 patients at two time points, before surgery and in 3 months after brain tumor resection surgery.

Results: There were significant correlations between CETI and the total scores on RAT subtests for speech comprehension and production before surgery but not in the follow-up period.

Increased cerebral blood volume and oxygen consumption in neonatal brain injury.

With the increasing interest in treatments for neonatal brain injury, bedside methods for detecting and assessing injury status and evolution are needed. We aimed to determine whether cerebral tissue oxygenation (StO(2)), cerebral blood volume (CBV), and estimates of relative cerebral oxygen consumption (rCMRO(2)) determined by bedside frequency-domain near-infrared spectroscopy (FD-NIRS) have the potential to distinguish neonates with brain injury from those with non-brain issues and healthy controls. We recruited 43 neonates < or =15 days old and >33 weeks gestational age (GA): 14 with imaging evidence of brain injury, 29 without suspicion of brain injury (4 unstable, 6 stable, and 19 healthy).

Noninvasive optical measures of CBV, StO(2), CBF index, and rCMRO(2) in human premature neonates' brains in the first six weeks of life.

With the causes of perinatal brain injuries still unclear and the probable role of hemodynamic instability in their etiology, bedside monitoring of neonatal cerebral hemodynamics with standard values as a function of age are needed. In this study, we combined quantitative frequency domain near infrared spectroscopy (FD-NIRS) measures of cerebral tissue oxygenation (StO(2)) and cerebral blood volume (CBV) with diffusion correlation spectroscopy (DCS) measures of a cerebral blood flow index (CBF(ix)) to test the validity of the CBV-CBF relationship in premature neonates and to estimate cerebral metabolic rate of oxygen (rCMRO(2)) with or without the CBF(ix) measurement. We measured 11 premature neonates (28-34 weeks gestational age) without known neurological issues, once a week from one to six weeks of age.
