The Neurological Impact of Repetitive Low-Level Blast Overpressure Exposure

Journal of Neurotrauma
Repetitive low-level blast overpressure exposure is an increasingly recognized occupational hazard for military, law enforcement, and specialist breaching personnel. Unlike high-level blast exposures that commonly result in overt traumatic brain injury, acute low-level blast events have not been demonstrated to produce clinically detectable concussion ...

Development of a Portable Tool for Screening Neuromotor Sequelae From Repetitive Low-Level Blast Exposure

Military Medicine, 2017
Blast exposure is a prevalent cause of mild traumatic brain injury (mTBI) in military personnel in combat. However, it is more common for a service member to be exposed to a low-level blast (LLB) that does not result in a clinically diagnosable mTBI. Recent research suggests that repetitive LLB exposure can result in symptomology similar to symptoms ...

Perspectives on repeated low-level blast and the measurement of neurotrauma in humans as an occupational exposure risk

Shock Waves, 2017
A pressing question in military medical research is the nature and degree of effects on the human brain from occupational repeated exposure to low-level explosive blast, but reliable and effective means to objectively measure such effects remain elusive. In survey results, headache, difficulty sleeping, irritability, cognitive impairment, and a variety

Cumulative Blast Impulse Is Predictive for Changes in Chronic Neurobehavioral Symptoms Following Low Level Blast Exposure during Military Training

Military Medicine
ABSTRACT Introduction Cumulative low-level blast exposure during military training may be a significant occupational hazard, increasing the risk of poor long-term outcomes in brain function. US Public Law 116-92 section 717 mandates that US Department of Defense agencies document the blast exposure of

Leukemic blasts are present at low levels in spinal fluid in one‐third of childhood acute lymphoblastic leukemia cases

Pediatric Blood & Cancer, 2016
AbstractBackgroundCentral nervous system (CNS) involvement is associated with relapse in childhood acute lymphoblastic leukemia (ALL) and is a diagnostic challenge.ProcedureIn a Nordic/Baltic prospective study, we assessed centralized flow cytometry (FCM) of locally fixed cerebrospinal fluid (CSF) samples versus local conventional cytospin‐based ...

Impact of Low-Level Blast Exposure From Military Training and Career Cumulation on Hearing Outcomes

Military Medicine
ABSTRACT Introduction Occupational trades expose military service members to unique sound exposure profiles, distinct in frequency and amplitude to those commonly studied in industrial settings. Characteristics of the energy exposure incurred through blast exposure exercises a distinct mechanism of ...

Laminated Glass Curtain Walls and Laminated Glass Lites Subjected to Low-Level Blast Loading

Journal of Structural Engineering, 2008
Linear elastic and nonlinear elastic analytical investigations are reported for a nearly conventional, laminated glass curtain wall with split screw spline mullions subjected to low-level blast loading. Responses dynamic stresses, deflections, and accelerations of the rectangular glass lites within the curtain wall are compared to those of identical ...

Short-duration, low-level subclinical primary blast induces neurovascular compromise, and increased MMP9 expression

Brain Research
Preclinical blast studies to date have demonstrated pathological changes to brain tissue over a range of overpressures and duration of exposure. While there is evidence of vascular leakage in some reports, there are few reports examining low-intensity, short duration primary blast in the sub-millisecond range.

Clarifying the Impact of Low-Level Blast Exposure on Service Members’ Brains: A Scientific Perspective on a Media Report

Military Medicine
Abstract Service members are frequently exposed to low-level, repetitive blast waves, raising concerns about potential brain injury. A New York Times video, “How Blast Waves Affect Troops’ Brains,” used a dramatic analogy of a beer bottle shattering under impact to illustrate the effects of blast waves on the brain.
