An Integrative Review of Cerebral Salt Wasting Syndrome.

BACKGROUND: Although cerebral salt wasting syndrome (CSWS) is widely recognized, its clinical characteristics, diagnostic criteria, and management have not been clearly defined. This study was undertaken to comprehensively review current literature and provide a more complete picture of CSWS. This review also aimed to provide information for nurses on how to differentiate cerebral salt wasting syndrome from syndrome of inappropriate antidiuretic hormone secretion. METHODS: An integrative review was performed. Searches were conducted between May and July 2018. The primary information sources were CINAHL, Google Scholar, MEDLINE, PubMed, Scopus, and Web of Science. Included articles were published from 1954 to July 2018. RESULTS: The essential features of CSWS are hyponatremia, hypovolemia, and increased urine output. Treatment regimens may be determined based on the acuity and severity of hyponatremia and hypovolemia as well as evident symptoms and signs. CONCLUSION: This review may help neuroscience nurses become knowledgeable about CSWS for the drafting of appropriate nursing care plans and also be able to differentiate CSWS from syndrome of inappropriate antidiuretic hormone secretion as early as possible for timely and proper management.

Angiopoietin-1/Tie-2 signal after focal traumatic brain injury is potentiated by BQ788, an ETB receptor antagonist, in the mouse cerebrum: Involvement in recovery of blood-brain barrier function.

Angiopoietin-1, an angiogenic factor, stabilizes brain microvessels through Tie-2 receptor tyrosine kinase. In traumatic brain injury, blood-brain barrier (BBB) disruption is an aggravating factor that induces brain edema and neuroinflammation. We previously showed that BQ788, an endothelin ETB receptor antagonist, promoted recovery of BBB function after lateral fluid percussion injury (FPI) in mice. To clarify the mechanisms underlying BBB recovery mediated by BQ788, we examined the involvements of the angiopoietin-1/Tie-2 signal. When angiopoietin-1 production and Tie-2 phosphorylation were assayed by quantitative reverse transcription polymerase chain reaction and western blotting, increased angiopoietin-1 production and Tie-2 phosphorylation were observed in 7-10 days after FPI in the mouse cerebrum, whereas no significant effects were obtained at 5 days. When BQ788 (15 nmol/day, i.c.v.) were administered in 2-5 days after FPI, increased angiopoietin-1 production and Tie-2 phosphorylation were observed. Immunohistochemical observations showed that brain microvessels and astrocytes contained angiopoietin-1 after FPI, and brain microvessels also contained phosphorylated Tie-2. Treatment with endothelin-1 (100 nM) decreased angiopoietin-1 production in cultured astrocytes and the effect was inhibited by BQ788 (1 µM). Five days after FPI, increased extravasation of Evans blue dye accompanied by reduction in claudin-5, occludin, and zonula occludens-1 proteins were observed in mouse cerebrum while these effects of FPI were reduced by BQ788 and exogenous angiopoietin-1 (1 µg/day, i.c.v.). The effects of BQ788 were inhibited by co-administration of a Tie-2 kinase inhibitor (40 nmol/day, i.c.v.). These results suggest that BQ788 administration after traumatic brain injury promotes recovery of BBB function through activation of the angiopoietin-1/Tie-2 signal.

Loss of guidewire and its sequelae after central venous catheterization: A case report.

RATIONALE: Central venous catheterization is a common tool used to monitor central venous pressure and administer fluid medications in patients undergoing surgery. The loss of a broken guide wire into the circulation is a rare and preventable complication. Here, we report a peculiar case of a missed guidewire puncturing the aortic arch and cerebrum. PATIENT CONCERNS: A 53-year-old man with complaints of an intermittent headache and right swollen ankle following central venous catheterization. DIAGNOSES: Using computed tomography; the patient was diagnosed with the loss of a guide wire in his body. The guide wire had migrated to the brain and punctured the vascular wall of the aortic arch. INTERVENTIONS: Due to the risks of surgery, the patient was advised to have a follow-up visit once every 3 months. OUTCOMES: At present, the patient could live like a normal person, although he suffers from intermittent headaches. LESSONS: The loss of a guide wire is a completely preventable complication, provided that a hold on the tip of the wire is maintained during placement, and the correct safety measurements and protocols are followed.

LncRNA FIRRE/NF-kB feedback loop contributes to OGD/R injury of cerebral microglial cells.

Stroke is one of the leading causes for serious long-term neurological disability. LncRNAs have been investigated to be dysregulated in ischemic stroke. However, the underlying mechanisms of some specific lncRNAs have not been clearly clarified. To determine lncRNA-mediated regulatory mechanism in ischemic stroke, we constructed OGD/R injury model of cerebral microglial cells. Microarray analysis was carried out and analyzed that lncRNA functional intergenic repeating RNA element (FIRRE) was associated with OGD/R injury. Based on the molecular biotechnology, we demonstrated that FIRRE could activate NF-kB signal pathway. Meanwhile, the activated NF-kB promoted FIRRE expression in OGD/R-treated cerebral microglial cells. Therefore, FIRRE and NF-kB formed a positive feedback loop to promote the transcription of NLRP3 inflammasome, thus contributed to the OGD/R injury of cerebral microglial cells. All findings in this study may help to explore novel and specific therapeutic target for ischemic stroke.

Routine cervical spine immobilisation is unnecessary in patients with isolated cerebral gunshot wounds: A South African experience.

OBJECTIVE: Routine immobilisation of the cervical spine in trauma has been a long established practice. Very little is known in regard to its appropriateness in the specific setting of isolated traumatic brain injury secondary to gunshot wounds (GSWs). METHODS: A retrospective study was conducted over a 5 year period (January 2010 to December 2014) at the Pietermaritzburg Metropolitan Trauma Service, Pietermaritzburg, South Africa in order to determine the actual incidence of concomitant cervical spine injury (CSI) in the setting of isolated cerebral GSWs. RESULTS: During the 5 year study period, 102 patients were included. Ninety-two per cent (94/102) were male and the mean age was 29 years. Ninety-eight per cent of the injuries were secondary to low velocity GSWs. Twenty-seven (26%) patients had cervical collar placed by the Emergency Medical Service. The remaining 75 patients had their cervical collar placed in the resuscitation room. Fifty-five (54%) patients had a Glasgow Coma Scale (GCS) of 15 and underwent plain radiography, all of which were normal. Clearance of cervical spine based on normal radiography combined with clinical assessment was achieved in all 55 (100%) patients. The remaining 47 patients whose GCS was <15 all underwent a computed tomography (CT) scan of their cervical spine and brain. All 47 CT scans of the cervical spine were normal and there was no detectable bone or soft tissue injury noted. CONCLUSION: Patients who sustain an isolated low velocity cerebral GSW are highly unlikely to have concomitant CSI. Routine cervical spine immobilisation is unnecessary, and efforts should be directed at management strategies aiming to prevent secondary brain injury. Further studies are required to address the issue in the setting of high velocity GSWs.

Autopsy Case of a Penetrating Wound to the Left Cerebral Hemisphere Caused by an Accidental Shooting With a Crossbow.

A crossbow is a bow that shoots an arrow when a gun-like trigger is pulled. Deaths caused by accidental crossbow shootings are extremely rare. Here we describe an autopsy case of a penetrating wound to the left cerebral hemisphere caused by an accidental shooting with a crossbow. A man in his early 60s who lived with his wife and had used crossbows for 20 years as his hobby was found one early morning in the shed of his house, collapsed and bleeding from the head and neck. He was taken to a hospital and died after approximately 3 days of conservative treatment. At autopsy, a penetrating wound between the upper part of the left anterior neck and the left frontoparietal region was evident. Traumatic intracerebral hematoma was observed in the left frontal lobe, and severe traumatic subarachnoid hemorrhage was present throughout the brain. Cerebral contusion and hematoma without any organization were noted around the penetration. The cause of death was determined to be cerebral contusion and intracerebral hematoma due to the penetrating wound by the crossbow arrow. He was probably trying to load an arrow into the crossbow by placing it on the floor, pointing upward, and made a mistake in its operation that resulted in the shooting of the arrow. This case is unique because it was a rare accidental death caused by a crossbow arrow, and a detailed histopathological examination was performed.

Neuroscience and education: We already reached the tipping point / Neurociencia y educación: ya hemos alcanzado el punto crítico

The aim of this contribution is to introduce the present Special Issue on Neuroscience and Education of the Revista de Psicología Educativa/Educational Psychology. After a brief introduction to current advances in general cognitive neuroscience that are being possible by means of brain imaging techniques available only during the most recent decades, we will discuss some aspects that have been contributing to hamper a true integration between both disciplines (neuroscience and education). The articles included in the present monograph provide empirical evidence that neuroscience has already reached a sufficient body of knowledge as to substantially improve education and political decisions in this respect. Neuroscience reveals that brain maturation extends at least until the second decade of life and that the exposition to different developmental experiences and opportunities is crucial along this extensive life period, so that none of its phases should be downplayed

Esta contribución pretende introducir y contextualizar el presente monográfico de la Revista de Psicología Educativa/Educational Psychology sobre neurociencia y educación. Tras introducir brevemente los avances que en neurociencia cognitiva, en general, se están alcanzando gracias a las técnicas de imagen cerebral disponibles sólo en las últimas décadas, se discuten algunos aspectos que han hecho difícil la verdadera integración entre ambas disciplinas (la neurociencia y la educación). Los artículos incluidos en este monográfico demostrarán que la neurociencia ofrece una cantidad más que suficiente de conocimiento acumulado como para aportar sustancialmente a la educación y a las políticas educativas. La neurociencia revela que la maduración cerebral no se alcanza hasta la segunda década de vida de la persona y que la exposición a diferentes experiencias y oportunidades de desarrollo es crucial a lo largo de toda esta extensa etapa vital, sin que debamos descuidar unos momentos más que otros

The emerging role of educational neuroscience in education reform / El papel emergente de la neurociencia educativa en la reforma de la educación

In the early 90s a movement began in education called "brain-based learning" that attempted to link neuroscience and education. However, many in both science and education felt it was untenable to make this leap. While early attempts to bridge the fields sparked controversy, it can now be argued that neuroscience does have a role to play in education reform. This paper explores suggestions for the appropriate training of the Educational Neuroscientist, broad interventions based on Educational Neuroscience that could reform curriculum, and emerging ways the Educational Neuroscientist can inform professional development of educators

A principios de los años 90 surgió un movimiento en educación llamado "aprendizaje basado en el cerebro" que trataba de unir neurociencia y educación. No obstante, muchas personas tanto en ciencia como en educación, pensaban que no era viable dar tal salto. Mientras que los primeros intentos por tender puentes entre estos campos suscitó controversia, puede decirse ahora que la neurociencia sí tiene un papel que jugar en la reforma de la educación. Este artículo explora propuestas para el adecuado entrenamiento del neurocientífico educativo, intervenciones amplias sustentadas en la neurociencia educativa que podrían reformar el currículum y de qué nuevas maneras podría contribuir neurocientífico educativo al desarrollo profesional de los educadores

Improvement of cold injury-induced mouse brain edema by endothelin ETB antagonists is accompanied by decreases in matrixmetalloproteinase 9 and vascular endothelial growth factor-A.

Brain edema is a potentially fatal pathological state that often occurs after brain injuries such as ischemia and trauma. However, therapeutic agents that fundamentally treat brain edema have not yet been established. We previously found that endothelin ETB receptor antagonists attenuate the formation and maintenance of vasogenic brain edema after cold injury in mice. In this study, the effects of ETB antagonists on matrixmetalloproteinase (MMP)9 and vascular endothelial growth factor (VEGF)-A expression were examined in the cold injury model. Cold injury was performed in the left brain of male ddY mice (5-6 weeks old) for the induction of vasogenic edema. Expression of MMP9 and VEGF-A mRNA in the mouse cerebrum was increased by cold injury. Immunohistochemical observations showed that the MMP9 and VEGF-A were mainly produced in reactive astrocytes in the damaged cerebrum. Intracerebroventricular administration of BQ788 (10 µg) or IRL-2500 (10 µg) (selective ETB antagonists) attenuated brain edema and disruption of the blood-brain barrier after cold injury. BQ788 and IRL-2500 reversed the cold injury-induced increases in MMP9 and VEGF-A expression. The induction of reactive astrocytes producing MMP9 and VEGF-A in the damaged cerebrum was attenuated by BQ788 and IRL-2500. These results suggest that attenuations of astrocytic MMP9 and VEGF-A expression by ETB antagonists may be involved in the amelioration of vasogenic brain edema.

Discapacidad intelectual y Neurociencia / No disponible

Ante el peligro de que la neurociencia sea vista y cuestionada como nueva herramienta al servicio del poder para marginar más sutilmente a la discapacidad intelectual, el autor analiza una reciente publicación de Altermark que parece acusar a la neurociencia de deslizarse en esa dirección. El artículo expone los fines, métodos y logros de la moderna neurociencia en el ámbito de la discapacidad intelectual, y defiende su extraordinaria aportación a la sociedad en general y a las personas con dicha condición en particular

In Altermark's view, modern neuroscience research may be underpinned by a discursive division between normal and pathological, thus enhancing the biopolitical power in the field of developmental disabilities. The author disclaims this opinion. He explains the aims, methods and achievements of neuroscience, which are contributing to a new age in the attention and care of individuals with mental disability

Contextual Constraint Treatment for coarse coding deficit in adults with right hemisphere brain damage: generalisation to narrative discourse comprehension.

Coarse coding is the activation of broad semantic fields that can include multiple word meanings and a variety of features, including those peripheral to a word's core meaning. It is a partially domain-general process related to general discourse comprehension and contributes to both literal and non-literal language processing. Adults with damage to the right cerebral hemisphere (RHD) and a coarse coding deficit are particularly slow to activate features of words that are relatively distant or peripheral. This manuscript reports a pre-efficacy study of Contextual Constraint Treatment (CCT), a novel, implicit treatment designed to increase the efficiency of coarse coding with the goal of improving narrative comprehension and other language performance that relies on coarse coding. Participants were four adults with RHD. The study used a single-subject controlled experimental design across subjects and behaviours. The treatment involved pre-stimulation, using a hierarchy of strong and moderately biased contexts, to prime the intended distantly related features of critical stimulus words. Three of the four participants exhibited gains in auditory narrative discourse comprehension, the primary outcome measure. All participants exhibited generalisation to untreated items. No strong generalisation to processing non-literal language was evident. The results indicate that CCT yields both improved efficiency of the coarse coding process and generalisation to narrative comprehension.

Navigational memory functional magnetic resonance imaging: a test for concussion in children.

Concussions are high incidence injuries with potentially devastating consequences. Youths are at risk because of a higher threat of repeated injury, and cumulative effects of concussions exist, making accurate diagnosis and follow-up essential. This study examines a navigational memory functional magnetic resonance imaging (fMRI) task to determine whether activation differences exist between children with concussion and uninjured controls. Fifty adolescents were recruited-35 controls and 15 with concussion. All subjects underwent structural and fMRI testing using our navigational memory task, and a battery of neuropsychological testing. The activation patterns of the 15 subjects with concussion were compared with those of 15 age and sex-matched controls. Subtraction and regression analyses were performed using the matched controls along with scatter-plots using means and 95% quantiles of the 35 controls. While no differences were seen with neuropsychological testing or task performance, subjects with concussion had significantly diminished activation in the retrosplenial, thalamic, and parahippocampal areas bilaterally, along with the right dorsolateral prefrontal cortex and left precuneus. Interestingly, they had increased activation in the left hippocampus and right middle temporal gyrus. Regression analysis demonstrated negative correlations between activation and post-concussive symptoms in the left premotor cortex, superior and inferior parietal lobules, and parahippocampal gyrus. Subjects with concussion show both diminished and increased activation in specific cerebral regions, differentiating them from controls. This is one of the first studies to look at such a task using fMRI and its applicability in testing for concussion in children. These findings support navigational memory fMRI as a potential objective test for concussions.
