Head Fracture to be Predicted With a Biomarker in Blood

Measuring markers of bone injury in the blood can help predict the likelihood of a cranial lesion and determine the need for head computed tomography, in cases of traumatic brain injury.

Measuring markers of bone injury in the blood can help predict the likelihood of a cranial lesion and determine the need for head computed tomography, in cases of traumatic brain injury. The results of a new study comparing the usefulness of two biomarkers released into the blood following a TBI are presented in Journal of Neurotrauma, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers.

The article "GFAP Out-Performs S100ß in Detecting Traumatic Intracranial Lesions on Computed Tomography in Trauma Patients with Mild Traumatic Brain Injury and Those with Extracranial Lesions," describes a study of adult trauma patients with and without mild or moderate TBI.

Head Injury | Brain Injury Overview Types Causes Symptoms Diagnosis Treatment
Head injury or traumatic brain injury is a leading cause of disability among children and young adults that leads to varying degrees of physical and mental stability. Fortunately, it is also one of the preventable brain disorder.

The authors, Linda Papa and colleagues from Orlando Regional Medical Center, North Florida Veteran's Health System and University of Florida (Gainesville), University of Central Florida (Orlando), Banyan Biomarkers Inc. (Alachua, FL), Virginia Commonwealth University (Richmond, VA), and Baylor College of Medicine (Houston, TX), showed that increased blood levels of glial fibrillary acidic protein (GFAP) following TBI was a good predictor of intracranial lesions, whether or not the patient had fractures elsewhere in the body. Whereas S100ß levels in the blood of were significantly higher in trauma patients with fractures than without fractures, it was not as useful as GFAP in distinguishing between intracranial and extracranial lesions.

John T. Povlishock, PhD, Editor-in-Chief of Journal of Neurotrauma and Professor, Medical College of Virginia Campus of Virginia Commonwealth University, Richmond, notes that "This is an extremely important paper because of its relatively large sample size and its singular focus upon mild traumatic brain injury complicated by the presence of extracranial lesions. This study convincingly demonstrates the efficacy and brain specific nature of GFAP and its ability to detect traumatic intracranial lesions while also calling into question the overall utility of S100ß in the same patient population. Importantly, the superior performance of GFAP in the mild brain injured population is an important observation consistent with other reports emerging in the field. Lastly, the observation that these GFAP elevations occur relatively early in a post-traumatic course speaks to the potential utility of using these biomarkers to screen brain injured patients who then may require more extensive and/or long term imaging studies."

High Doses of Vitamin D Beneficial in Preventing Fractures
Vitamin D is essential for the proper absorption of dietary phosphorus and calcium. This absorption influences the bone mineral density that is directly responsible for fractures and osteoporosis.

Probiotics Reduce Duration of ICU Stay in Critically Ill Patients
Probiotics can safely be used in critically ill patients. They decrease the duration of ICU stay and also reduce the incidence of nosocomial infections.
