BACKGROUND: Intensive Care to facilitate Organ Donation (ICOD) may help to increase the donor pool. We describe the Spanish experience with ICOD. METHODS: ACCORD-Spain consisted of an audit of the donation pathway from patients dead as a result of a devastating brain injury (possible donors) in 68 hospitals during 11/1/2014-4/30/2015. We focused on possible donors whose family was interviewed to discuss organ donation once intensive care with a therapeutic purpose was deemed futile and brain death (BD) was a likely outcome...

BACKGROUND: Traumatic brain injury (TBI) is a devastating neurological condition and a frequent cause of permanent disability. Posttraumatic inflammation and brain edema formation, two pathological key events contributing to secondary brain injury, are mediated by the contact-kinin system. Activation of this pathway in the plasma is triggered by activated factor XII. Hence, we set out to study in detail the influence of activated factor XII on the abovementioned pathophysiological features of TBI...

Although the most recent MBRRACE-UK (Mothers and Babies: Reducing Risk through Audits and Confidential Enquiries across the UK) perinatal mortality report has shown a downward trend in perinatal mortality, the UK still lags behind the best-performing countries in Europe. The burden of perinatal morbidity and mortality is wide-reaching and devastating for the families and care-providers involved. The aim of the Each Baby Counts (EBC) project is to reduce intrapartum term stillbirths, early neonatal deaths, and severe brain injuries by 50% by 2020...

The recent clinical availability of the PARP inhibitor Lynparza (olaparib) opens the door for potential therapeutic repurposing for non-oncological indications. Considering (a) the preclinical efficacy data with PARP inhibitors in non-oncological diseases and (b) the risk-benefit ratio of treating patients with a compound that inhibits an enzyme that has physiological roles in the regulation of DNA repair, indications where (a) the severity of the disease is high, (b) the available therapeutic options are limited, and (c) the duration of PARP inhibitor administration could be short, provide first-line options for therapeutic repurposing...

Traumatic spinal cord injury (SCI) is a devastating neurological condition characterized by a constellation of symptoms including paralysis, paraesthesia, pain, cardiovascular, bladder, bowel and sexual dysfunction. Current treatment for SCI involves acute resuscitation, aggressive rehabilitation and symptomatic treatment for complications. Despite the progress in scientific understanding, regenerative therapies are lacking. In this review, we outline the current state and future potential of invasive and non-invasive neuromodulation strategies including deep brain stimulation (DBS), spinal cord stimulation (SCS), motor cortex stimulation (MCS), transcutaneous direct current stimulation (tDCS) and repetitive transcranial magnetic stimulation (rTMS) in the context of SCI...

Coagulopathy is common in intensive care units (ICUs). Many physiologic derangements lead to dysfunctional hemostasis; these may be either congenital or acquired. The most devastating outcome of coagulopathy in the critically ill is major bleeding, defined by transfusion requirement, hemodynamic instability, or intracranial hemorrhage. ICU coagulopathy often poses complex management dilemmas, as bleeding risk must be tempered with thrombotic potential. Coagulopathy associated with intracranial hemorrhage bears directly on prognosis and outcome...

Deficits in attention are a common and devastating consequence of traumatic brain injury (TBI), leading to functional impairments, rehabilitation barriers, and long-term disability. While such deficits are well documented, little is known about their underlying pathophysiology hindering development of effective and targeted interventions. Here we evaluate the integrity of brain systems specific to attentional functions using quantitative assessments of electroencephalography recorded during performance of the Attention Network Test (ANT), a behavioral paradigm that separates alerting, orienting, and executive components of attention...

Spinal cord injury (SCI) is a devastating condition that affects patient on a personal as well as on a societal level. The objective of the study is to improve the prediction of long-term functional outcome following SCI based on the acute clinical findings. 76 patients with acute traumatic SCI were prospectively enrolled in a cohort study in a single level I trauma center. Spinal Cord Independence Measure (SCIM) at 1 year after the trauma was the primary outcome. Potential predictors of functional outcome were recorded during the acute hospitalization: age, sex, level and type of injury, comorbidities, American Spinal Injury Association (ASIA) Impairment Scale (AIS), ASIA Motor Score (AMS), ASIA Light Touch score (LT), ASIA Pin Prick score (PP), Injury Severity Score (ISS), Traumatic Brain Injury (TBI) and delay from trauma to surgery...

The underlying pathophysiology of primary open-angle glaucoma remains unclear, but the lamina cribrosa seems to be the primary site of injury and raised intraocular pressure is a major risk factor. In recent years, a decreased intracranial pressure, leading to an abnormally high trans-lamina cribrosa pressure difference, has gained interest as a new risk factor for glaucoma. New research now lends support to the hypothesis that a paravascular transport system is present in the eye analogous to the recently discovered 'glymphatic system' in the brain, which is a functional waste clearance pathway that promotes elimination of interstitial solutes, including amyloid-β, from the brain along paravascular channels...

Perioperative bleeding is a potentially devastating complication in neurosurgical patients, and plasma fibrinogen concentration has been identified as a potential modifiable risk factor for perioperative bleeding. The aim of this study was to evaluate preconditioning with Crotalus atrox venom (Cv-PC) as potential preventive therapy for reducing perioperative hemorrhage in the rodent model of surgical brain injury (SBI). C. atrox venom contains snake venom metalloproteinases that cleave fibrinogen into fibrin split products without inducing clotting...

In spite of recent advances in the treatment of epilepsy, up to 35% of people living with the condition do not respond to accessible anti-epileptic drugs (AEDs) and continue to experience regular, devastating and potentially life-threatening seizures. Neuronal death is a significant feature of epilepsy in humans and experimental models. It has been reported that apelin, an endogenous ligand for the angiotensin-1-like receptor (APJ), has anticonvulsive as well as protective effects in some neurodegenerative situations...

Ischemic stroke is a devastating condition with few therapeutic interventions available. The neuroprotective compound P7C3-A20 inhibits mature neuronal cell death while also increasing the net magnitude of postnatal neurogenesis in models of neurodegeneration and acute injury. P7C3 compounds enhance flux of nicotinamide adenine dinucleotide (NAD) in mammalian cells, a proposed therapeutic approach to treating cerebral ischemia. The effectiveness of P7C3-A20 treatment on chronic histopathological and behavioral outcomes and neurogenesis after ischemic stroke has not previously been established...

Concussions carry devastating potential for cognitive, neurologic, and socio-emotional disease, but no objective test reliably identifies a concussion and its severity. A variety of neurological insults compromise sound processing, particularly in complex listening environments that place high demands on brain processing. The frequency-following response captures the high computational demands of sound processing with extreme granularity and reliably reveals individual differences. We hypothesize that concussions disrupt these auditory processes, and that the frequency-following response indicates concussion occurrence and severity...

A growing body of clinical literature emphasizes the impact of cerebral edema in early brain injury following aneurysmal subarachnoid hemorrhage (aSAH). Aneurysm rupture itself initiates global cerebral edema in up to two thirds of cases. Although cerebral edema is not a universal feature of aSAH, it portends a poor clinical course, with quantitative analysis revealing a direct correlation between cerebral edema and poor outcome, including mortality and cognitive deficits. Mechanistically, global cerebral edema has been linked to global ischemia at the time of aneurysm rupture, dysfunction of autoregulation, blood breakdown products, neuroinflammation, and hyponatremia/endocrine abnormalities...

Spontaneous intracranial hemorrhage (ICH) remains a devastating stroke subtype, affecting as many as 80,000 people annually in the United States and associated with extremely high mortality. In the absence of any pharmacological interventions demonstrated to improve outcome, care for patients with ICH remains largely supportive. Thus, despite advances in the understanding of ICH and brain injury, there remains an unmet need for interventions that improve neurologic recovery and outcomes. Recent research suggesting inflammation and APOE genotype play a role in modifying neurologic outcome after brain injury has led to the development of an APOE-derived peptide agent (CN-105)...

The progressive loss and degeneration of neurons in the central nervous system (CNS), as a result of traumas or diseases including Alzheimer's, Parkinson's, Huntington's disease, stroke, and traumatic injury to the brain and spinal cord, can usually have devastating effects on quality of life. The current strategies available for treatments are described including drug delivery, surgery, electrical stimulation, and cell-based tissue engineering approaches. However, apart from cell-based therapy, other attempts are limited in improving clinical outcomes...

Severe intraventricular hemorrhage (IVH) remains a major cause of mortality and longterm neurologic morbidities in premature infants, despite recent advances in neonatal intensive care medicine. Several preclinical studies have demonstrated the beneficial effects of mesenchymal stem cell (MSC) transplantation in attenuating brain injuries resulting from severe IVH. Because there currently exists no effective intervention for severe IVH, the therapeutic potential of MSC transplantation in this intractable and devastating disease are creating excitement in this field...

BACKGROUND: Spinal cord injury (SCI) is a devastating condition with limited therapeutic options despite decades of research. Current treatment options include use of steroids, surgery, and rehabilitation. Nevertheless, many patients with SCI remain disabled. MLC601 (NeuroAiD), a combination of natural products, has been shown to be safe and to aid neurological recovery after brain injuries and may have a potential role in improving recovery after SCI. OBJECTIVE: The aim of this study is to evaluate the safety and efficacy of NeuroAiD amongst people who sustain SCI in the study setting...

Decompressive craniectomy (DC) after devastating brain injury (DBI) may influence the manner in which patients die, having implications for end-of-life care and organ donation. We performed a retrospective review of deaths following a non-traumatic DBI between 2008 and 2012. 160 patients were reviewed; 26 were treated with DC and 134 received standard care. There was no relationship between DC and mechanism of death, (OR 1.18, 95% CI 0.44-3.17). Prospective studies are required to confirm these preliminary finding...

The management of higher brain dysfunctions such as stroke-induced unilateral spatial neglect (USN) or aphasia is crucial because these dysfunctions have devastating neurological repercussions on the patients' daily life and quality of life. Impairment of the physiological interhemispheric rivalry is often the result of brain insults such as strokes or traumatic injuries, and it may lead to USN or aphasia. Repetitive transcranial magnetic stimulation (rTMS), a non-invasive brain stimulation method, is a promising tool for restoring the pathological imbalance in interhemispheric rivalry by either suppressing the hyperactivity of the unaffected hemisphere or facilitating hypoactivity in the affected hemisphere...
