Low levels of blast raises intracranial pressure and impairs cognitive function in rats

Journal of Neurotrauma, 2009
Brain injury after high-level blast has been established both clinically and experimentally. Less is known about the effects on the brain of exposure to low to moderate blast levels, such as those encountered by military personnel during the firing of weapons.

Repeated Occupational Exposure to Low-level Blast in the Canadian Armed Forces: Effects on Hearing, Balance, and Ataxia

Military Medicine, 2021
ABSTRACT Introduction Recently, there has been increasing concern about the adverse health effects of long-term occupational exposure to low-level blast in military personnel. Occupational blast exposure occurs routinely in garrison through use of armaments and controlled blast detonations.

The Effects of Low-level Repetitive Blasts on Neuropsychological Functioning

2015
Abstract : Despite increased research on blast-related mild traumatic brain injury (mTBI), relatively little is understood about long-term symptomatology. The primary objective of this study was to determine whether repeated exposure to low-level controlled blasts produces observable changes in cognitive functioning and psychological health. The target

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

Mild Traumatic Brain Injury From Repeated Low-Level Blast Exposures

Volume 3: Biomedical and Biotechnology Engineering, 2015
Recent studies on military breachers in training environments suggest that there are neurocognitive risks from exposure to repeated low-level blasts. However, the dose accumulation effects from multiple low-level blast exposures and their relation to mild traumatic brain injury (mTBI) are not well understood.

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 ...

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 ...

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

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 ...
