BACKGROUND: Many investigators endeavor to predict the outcome based on admission characteristics using some established models to determine which management should be applied. However, the efficacy and applicability of the models using in the geriatric severe traumatic brain injury (TBI) patients have not been evaluated yet. METHODS: 137 geriatric severe TBI patients were enrolled in this retrospective study. Receiver operating characteristics (ROC) curves were constructed to evaluate the efficacy and usability of the IMPACT prognostic model in evaluating the prognosis for these patients...

BACKGROUND: Little is known about the long-term course of headache in patients with moderate-to-severe headache due to traumatic brain injury (TBI). We evaluated the course of headache in patients with moderate-to-severe headache due to mild TBI. METHODS: Since September 2009, patients with TBI prospectively rated their headache using a numeric rating scale (NRS). From the database containing 935 patients with TBI between September 2009 and December 2013, 259 patients were included according to following criteria: (1) newly onset moderate-to-severe headache (NRS ≥ 4) due to head trauma; (2) age ≥ 15 years; (3) Glasgow Coma Scale ≥ 13; (4) transient loss of consciousness ≤ 30 min; and (5) radiographic evaluation, such as computed tomography or magnetic resonance image...

A somewhat perplexing finding in the systems neuroscience has been the observation that physical injury to neural systems may result in enhanced functional connectivity (i.e., hyperconnectivity) relative to the typical network response. The consequences of local or global enhancement of functional connectivity remain uncertain and this is particularly true for the overall metabolic cost of the network. We examine the hyperconnectivity hypothesis in a sample of 14 individuals with TBI with data collected at approximately 3, 6, and 12 months following moderate and severe TBI...

Valued living (VL) is associated with improved enjoyment and engagement with daily activities despite negative emotional state or ongoing pain. However, the role of VL in recovery following traumatic brain injury (TBI) has yet to be investigated. This study aimed to examine changes in VL over the course of recovery and variables associated with VL. Participants with moderate-to-severe TBI were recruited from a rehabilitation hospital in three cohorts: "Early" (n = 25), "Mid" (n = 9) and "Late" (n = 36) post-TBI...

Traumatic brain injury (TBI) induces cognitive impairments, motor and behavioral deficits. Previous evidences have suggested that neural stem cell (NSC) transplantation could facilitate functional recovery from brain insults, but their underlying mechanisms remains to be elucidated. Here, we established TBI model by an electromagnetic-controlled cortical impact device in the rats. Then, 5 μl NSCs (5.0 × 10(5)/μl), derived from green fluorescent protein (GFP) transgenic mouse, was transplanted into the traumatic brain regions of rats at 24 h after injury...

Studies in vivo and in vitro have suggested that the mechanism underlying Alzheimer's disease (AD) neuropathogenesis is initiated by an interaction between the cellular prion protein (PrP(C)) and amyloid-β oligomers (Aβo). This PrP(C)-Aβo complex activates Fyn kinase which, in turn, hyperphosphorylates tau (P-Tau) resulting in synaptic dysfunction, neuronal loss and cognitive deficits. AD transgenic mice lacking PrP(C) accumulate Aβ, but show normal survival and no loss of spatial learning and memory suggesting that PrP(C) functions downstream of Aβo production but upstream of intracellular toxicity within neurons...

The majority of patients with mild traumatic brain injury (mTBI) will have normal Glasgow coma scale (GCS) of 15. Furthermore, only 5%-8% of them will be CT-positive for an mTBI. Having a useful biomarker would help clinicians evaluate a patient's risk of developing intracranial lesions. The S100B protein is currently the most studied and promising biomarker for this purpose. Heart fatty-acid binding protein (H-FABP) has been highlighted in brain injury models and investigated as a biomarker for stroke and severe TBI, for example...

Intact epithelial body surfaces represent physical barriers which protect the organism from invading pathogens and loss of nutrients. Barrier malfunction is closely linked to disorders such as inflammatory bowel disease and graft-versus-host disease. In fact, several pharmacological or radiobiological therapeutic strategies have side effects that affect epithelial surfaces. In this context, assays that accurately assess epithelial barrier integrity in patients and animal models are crucial to create a better understanding of the mechanisms leading to disease or limiting therapeutic approaches due to barrier disruption...

Mechanical properties of brain tissue are crucial to understand the mechanism of traumatic brain injury (TBI). Over the past several decades, most of the studies focused on healthy brain tissues, while few of them are about the injured tissues. Therefore, limited knowledge is known about the mechanical properties of the injured brain tissues. In this study, we used an in vivo mouse model with a weight drop device to study injured brain tissues. Around the injury site, mechanical properties of the injured, neighboring, and the corresponding contralateral regions of interest (ROIs) were measured over five temporal points by indentation...

BACKGROUND: Clinical decision rules can help to determine the need for CT imaging in children with head injuries. We aimed to validate three clinical decision rules (PECARN, CATCH, and CHALICE) in a large sample of children. METHODS: In this prospective observational study, we included children and adolescents (aged <18 years) with head injuries of any severity who presented to the emergency departments of ten Australian and New Zealand hospitals. We assessed the diagnostic accuracy of PECARN (stratified into children aged <2 years and ≥2 years), CATCH, and CHALICE in predicting each rule-specific outcome measure (clinically important traumatic brain injury [TBI], need for neurological intervention, and clinically significant intracranial injury, respectively)...
