Kessler researchers link left-sided brain injury with greater risk for hospital-acquired infections

Findings published in March Archives of Physical Medicine & Rehabilitation have implications for translational research into brain-mediated immune defenses, infection control practices and cognitive rehabilitation strategies after stroke and brain injury
West Orange, NJ. February 28, 2013. The March 2013 issue of Archives of Physical Medicine & Rehabilitation, the medical journal of the American Congress of Rehabilitation Medicine, features an article by Kessler researchers Pasquale Frisina, PhD, Ann Kutlik, BA, and A.M. Barrett, MD. Left-sided brain injury associated with more hospital-acquired infections during inpatient rehabilitation (http://dx.doi.org/10.1016/j.apmr.2012.10.012) has implications for further research into brain-mediated immune defenses, infection control practices and cognitive rehabilitation strategies to improve outcomes after stroke and traumatic brain injury. The study was supported by Kessler Foundation and the National Institutes of Health (grant nos. R01NS055808, K24HD062647).
The authors, a team of stroke specialists from Kessler Foundation and Kessler Institute for Rehabilitation, report findings of a retrospective study of 2236 inpatients with brain lesions caused by traumatic brain injury or stroke. Hospital-acquired infection (HAI), a common complication that adversely affects outcomes and costs, was defined as infection diagnosed within 48 to 72 hours of admission. Of the 163 patients identified as having hospital-acquired infections, 60.1% had left-sided lesions. This finding was consistent with the hypothesis that a left-dominant brain immune network (LD-BIN) may influence the occurrence of HAI during inpatient rehabilitation for stroke and TBI.
These findings may help healthcare providers predict who is most susceptible to HAI, according to lead author Pasquale Frisina, PhD, which could help reduce mortality rates, control costs of care and improve outcomes. “The study indicates that antisepsis may not be the best or sole method to manage infection risk after stroke and brain injury,” said Dr. Frisina. “Future research should focus on ways to optimize the LD-BIN to improve health. These may include brain stimulation techniques such as direct electrical stimulation of the prefrontal brain or behavioral techniques such as mental/cognitive exercise.” He added that this investigative approach might lead to novel interventions aimed at increasing infection resistance, rather than on reducing or eradicating pathogens.
“Clinicians rarely think about the brain and immunity,” noted A.M. Barrett, MD, “but the balance between left and right brain activity is known to affect our infection resistance. I'm proud to be part of scientific activities that ask these kinds of innovative questions, and get answers that become the basis for new, improved processes for clinical care.”

About the Archives of Physical Medicine and Rehabilitation
The Archives of Physical Medicine and Rehabilitation advances the art and science of interdisciplinary rehabilitation, and is the premier source for researchers and clinicians to obtain authoritative information on the therapeutic utilization of physical, behavioral, and pharmaceutical agents in providing comprehensive care for individuals with chronic illness and disabilities. The journal publishes original, peer-reviewed articles that report on important trends and developments in physical medicine and rehabilitation and are relevant to all members of medical rehabilitation teams, including physicians, nurses, counselors, therapists and case managers. Archives began publication in 1920; it publishes monthly, and is the official journal of the American Congress of Rehabilitation Medicine. Archives is the most highly cited journal in Rehabilitation, has the highest Eigenfactor in the category, and has an Impact Factor that has increased eight of the past nine years. (2011 Journal Citation Reports®, Thomson Reuters). In 2009, the Archives of Physical Medicine and Rehabilitation was identified by the Special Libraries Association as one of the 100 most influential journals of Biology & Medicine over the last 100 years. www.archives-pmr.org
