OBJECTIVES: The quality of the relationship between patients with many illnesses and their family members has been shown to affect the well-being of both. Yet, relationship quality has not been studied in traumatic brain injury (TBI), and giving and receiving aspects have not been distinguished. The present study of veterans with TBI examined associations between relationship quality and caregiver burden, satisfaction with caregiving, and veterans' competence in interpersonal functioning, rated by veterans and family members...

INTRODUCTION: Neurogenic heterotopic ossification (NHO) is a complication of a neurological injury following traumatic brain injury (TBI) and may be present around major synovial joints. It is often accompanied by severe pain, which may lead to limitation in activities of daily living. Currently, a common intervention for NHO is surgery, which has been reported to carry many additional risks. This study was designed to assess the effect of extracorporeal shock wave therapy (ESWT) on pain in patients with TBI with chronic NHO...

The presence of hemosiderin in the optic nerve sheath and/or retina is sometimes used to estimate the timing of injury in infants or children with suspected non-accidental head trauma. To determine the prevalence of hemosiderin in deaths not associated with trauma, we performed a prospective study of retroocular orbital tissue, cranial convexity, and cervical spinal cord dura mater in infants and children <2.5 years age. In 53 cases of non-traumatic death, approximately 70% had blood or hemosiderin within the orbital fat, ocular muscles, and parasagittal cranial and/or cervical spinal subdural compartment...

Diffuse axonal injury (DAI) is the most common and significant pathological features of traumatic brain injury (TBI). However, there are still no effective drugs to combat the formation and progression of DAI in affected individuals. FK506, also known as tacrolimus, is an immunosuppressive drug, which is widely used in transplantation medicine for the reduction of allograft rejection. Previous studies have identified that FK506 may play an important role in the nerve protective effect of the central nervous system...

Early identification of non-accidental trauma (NAT) is a critical component of pediatric trauma care. Literature searches were conducted related to the association of NAT with seven key areas: history, exam findings (burns, oral trauma, bruising) and imaging (fractures, abdominal and brain injuries). When available, odds ratios (OR) with 95% confidence intervals (CI) for associations with NAT are presented. Systematic reviews have been published in six of the seven key areas and are described. The operational definition of NAT was widely variable across studies, prohibiting meta-analysis...

INTRODUCTION: Chronic traumatic encephalopathy (CTE) is a neurodegenerative disease linked to repetitive head injuries. CTE symptoms include changes in mood, behavior, cognition and motor function, however CTE is only currently diagnosed post-mortem. Using a rat model of recurrent traumatic brain injury (TBI) we demonstrate rodent deficits that predict the severity of CTE-like brain pathology. METHODS: Bilateral, closed skull, mild TBI was administered once per week to 35 WT rats, 8 rats received 2 injuries ('2xTBI'), 27 rats received 5 injuries ('5xTBI') and 13 rats were sham controls...

OBJECTIVE Contralateral peripheral neurotization surgery has been successfully applied to rescue motor function of the hemiplegic upper extremity in patients with central neurological injury (CNI). It may contribute to strengthened neural pathways between the contralesional cortex and paretic limbs. However, the effect of this surgery in the lower extremities remains unknown. In the present study the authors explored the effectiveness and safety of contralateral peripheral neurotization in treating a hemiplegic lower extremity following CNI in adult rats...

The blood-brain barrier (BBB) exhibits a highly selective permeability to support the homeostasis of the central nervous system (CNS). The tight junctions in the BBB microvascular endothelial cells seal the paracellular space to prevent diffusion. Thus, disruption of tight junctions results in harmful effects in CNS diseases and injuries. It has recently been demonstrated that glucocorticoids have beneficial effects on maintaining tight junctions in both in vitro cell and in vivo animal models. In the present study, we found that dexamethasone suppresses the expression of JMJD3, a histone H3K27 demethylase, via the recruitment of glucocorticoid receptor α (GRα) and nuclear receptor co-repressor (N-CoR) to the negative glucocorticoid response element (nGRE) in the upstream region of JMJD3 gene in brain microvascular endothelial cells subjected to TNFα treatment...

BACKGROUND: Traumatic brain injury (TBI) causes brain dysfunction in many patients. Using C-11 flumazenil (FMZ) positron emission tomography (PET), we have detected and reported the loss of neuronal integrity, leading to brain dysfunction in TBI patients. Similarly to FMZ PET, I-123 iomazenil (IMZ) single photon emission computed tomography (SPECT) is widely used to determine the distribution of the benzodiazepine receptor (BZR) in the brain cortex. The purpose of this study is to examine whether IMZ SPECT is as useful as FMZ PET for evaluating the loss of neuronal integrity in TBI patients...

INTRODUCTION: The association between age at injury (AAI) and long-term cognitive outcome of traumatic brain injuries (TBI) is debatable. METHODS: Eligible participants with a history of TBI from Alzheimer's Disease Neuroimaging Initiative were divided into a childhood TBI (cTBI) group (the AAI ≤ 21 years old) and an adult TBI (aTBI) group (the AAI > 21 years old). RESULTS: The cTBI group has a higher Everyday Cognition total score than the aTBI group...

Brain injury secondary to birth asphyxia is the major cause of death and long-term disability in newborns. Intranasal drug administration enables agents to bypass the blood-brain barrier (BBB) and enter the brain directly. In this study, we determined whether intranasal basic fibroblast growth factor (bFGF) could exert neuroprotective effects in neonatal rats after hypoxic-ischaemic (HI) brain injury and assessed whether attenuation of endoplasmic reticulum (ER) stress was associated with these neuroprotective effects...

This study was to test the hypothesis that tetramethylpyrazine (TMP) protected against early brain injury after subarachnoid hemorrhage (SAH) by affecting the mitochondrial-dependent caspase-3 apoptotic pathway. TMP was administrated after the rats' prechiasmatic SAH mode. Animal neurobehavioral functions were assessed and the mitochondrial morphology, mitochondrial and cytoplasmic calcium, and mitochondrial membrane potential changes (Δψm) of the brain tissues were measured. The expressions of cytoplasmic cytochrome c (cyt c), second mitochondria-derived activator of caspases (Smac), and cleaved caspase-3 B-cell lymphoma 2 (bcl-2) in cells were determined and cellular apoptosis was detected...

Interhemispheric interaction has a major role in various neurobehavioral functions. Its disruption is a major contributor to the pathological changes in the setting of brain injury such as traumatic brain injury, peripheral nerve injury, and stroke, as well as neurodegenerative diseases. Because interhemispheric interaction has a crucial role in functional consequence in these neuropathological states, a review of noninvasive and state-of-the-art molecular based neuromodulation methods that focus on or have the potential to elucidate interhemispheric interaction have been performed...

Neuroinflammation has been identified as a causative factor of multiple neurological diseases. The nucleotide-binding oligomerization domain-, leucine-rich repeat- and pyrin domain-containing 3 (NLRP3) inflammasome, a subcellular multiprotein complex that is abundantly expressed in the central nervous system (CNS), can sense and be activated by a wide range of exogenous and endogenous stimuli such as microbes, aggregated and misfolded proteins, and adenosine triphosphate, which results in activation of caspase-1...
