Despite advances in surgical and medical treatments, brain tumors continue to be associated with a dismal prognosis, specifically for glioblastoma multiforme (GBM), for which the short median survival time is only 15 months at best.20 Consequently, there has been emphasis on subspecialization within surgical neurooncology and a drive to promote the care of these patients by specialists who practice predominantly surgical neurooncology. Many centers operate in this way, such that certain neurosurgeons are responsible for the treatment and care of these patients.A recent development in the management of these cases has been a topic of debate in the United Kingdom. OBJect Surgeries for CNS tumors are frequently performed by general neurosurgeons and by those who specialize in surgical neurooncology. Subspecialization in neurosurgical practice has become common and may improve patient morbidity and mortality rates. However, the potential benefits for patients of having their surgeries performed by surgical neurooncologists remain unclear. Recently, a shift in patient care to those who practice predominantly surgical neurooncology has been promoted. Evidence for this practice is lacking and therefore requires fundamental investigation. MetHODS The authors conducted a case-control study of neurooncology patients who underwent surgery for glioblastoma and anaplastic astrocytoma during 2006-2009. Outcomes were compared for patients whose surgery was performed by general neurosurgeons (generalists) or by specialist neurooncology neurosurgeons (specialists). An electronic record database and a picture archiving and communication system were used to collect data and assess the extent of tumor resection. Mortality rates and survival times were compared. Patient comorbidity and postoperative morbidity were assessed by using the Waterlow, patient handling, and falls risk assessment scores. Effects of case mix were adjusted for by using Cox regression and a hazards model. reSUltS Outcomes for 135 patients (65 treated by generalists and 70 by specialists) were analyzed. Survival times were longer for patients whose surgery was performed by specialists (p = 0.026) and after correction for case mix (p = 0.019). Extent of tumor resection was greater when performed by specialists (p = 0.005) and correlated with increased survival times (p = 0.004). There was a trend toward reduced surgical deaths when surgery was performed by specialists (2.8%) versus generalists (7%) (p = 0.102), and inpatient stays were significantly shorter when surgery was performed by specialists (p = 0.008). cONclUSiONS The prognosis for glioblastoma multiforme remains dire, and improved treatments are urgently needed. This study provides evidence for a survival benefit when surgery is performed by specialist neurooncology neurosurgeons. The benefit might be attributable to increased tumor resection. Furthermore, specialist neurooncology surgical care may reduce the number of surgical patient deaths and length of inpatient stay. These findings support the rec...

In spinal cord injury (SCI), neuronal and oligodendroglial loss occurs as a result of the initial trauma and the secondary damage that is triggered by excitotoxicity, free radicals, and inflammation. There is evidence that SCI ellicits increased cytosolic phospholipase A(2) (cPLA(2)) activity. The cleavage of phospholipids by cPLA(2) leads to release of fatty acids, and in particular arachidonic acid (AA), the metabolites of which have been associated with increased inflammation and oxidative stress. The aim of our study was to investigate whether the inhibition of cPLA(2) following SCI leads to tissue protection and an improved functional outcome. Adult rats received compression SCI and 30 min after injury they were treated intravenously with either saline or the cPLA(2) inhibitor arachidonyl trifluoromethyl ketone (AACOCF3) (7.13 mg/kg). The animals were sacrificed at 7 days post-injury and the lesioned tissue was labeled using markers for neurons, oligodendrocytes, and macrophages/activated microglia. We also assessed locomotor recovery using the Basso-Beattie-Bresnahan (BBB) score. The number of surviving neurons and oligodendrocytes was significantly increased in animals treated with the cPLA(2) inhibitor compared to saline controls. The behavioral analysis mirrored the neuroprotective effects and showed that the inhibitor-treated group had better locomotor recovery compared to saline controls. Our results show that AACOCF3 has neuroprotective potential, and support the idea that cPLA(2) is critically involved in acute spinal injury.

Junior doctors go through a challenging transition upon qualification; this repeats every time they start a rotation in a new department. Foundation level doctors (first 2 years postqualification) in neurosurgery are often new to the specialty and face various challenges that may result in significant workplace dissatisfaction. The neurosurgical environment is a clinically demanding area with a high volume of unwell patients and frequent emergencies – this poses various barriers to learning in the workplace for junior doctors. We identify a number of key barriers and review ideas that can be trialed in the department to overcome them. Through an evaluation of current suggestions in the literature, we propose that learning opportunities need to be made explicit to junior doctors in order to encourage them to participate as a member of the team. We consider ideas for adjustments to the induction program and the postgraduate medical curriculum to shift the focus from medical knowledge to improving confidence and clinical skills in newly qualified doctors. Despite being a powerful window for opportunistic learning, the daily ward round is unfortunately not maximized and needs to be more learner focused while maintaining efficiency and time consumption. Finally, we put forward the idea of an open forum where trainees can talk about their learning experiences, identify subjective barriers, and suggest solutions to senior doctors. This would be achieved through departmental faculty development. These interventions are presented within the context of the neurosurgical ward; however, they are transferable and can be adapted in other specialties and departments.

ObjectiveWe aim to study the effect of persistent post-concussive symptoms on cognitive performance of elite athletes, based on the hypothesis that persistent symptoms could impair athletes’ cognitive performances and functional outcomes.DesignProspective observational and longitudinal case control study.SettingUniversity research centre, single centre.Participants7 athletes with persistent symptoms (>2 weeks, assessed at median 31 days post-concussion), 10 athletes with brief symptoms (<3 days, assessed within a week, median 3.5 days), and 9 age-matched healthy volunteers. Inclusion criteria: male/female athletes (aged 18–40) in contact sports who sustained concussion(s) recently, being symptomatic with normal neuro-radiological findings at enrolment.InterventionIndependent variables: post-concussive symptom scores and duration of symptoms.Outcome measuresMulti-dimensional scores from Sport Concussion Assessment Tool III, Immediate Post-concussion Assessment and Cognitive Testing, WAIS symbol search and digit span backward tests.Main resultsPatients with persistent symptoms scored less in the symbol search test than those with brief symptoms and the healthy volunteers (grouping effect p=0.006; post hoc tests p=0.039 and 0.004, respectively). In all 17 patients, symptom scores correlated with reaction time (ρ=−0.61, p=0.009), and visual motor speed correlated with symbol search scores (ρ=0.59, p=0.013). 6 patients who completed follow-up assessments when symptom-free showed improvement in their symbol search scores (p=0.042) and visual memory (p=0.028).ConclusionsConcussed athletes with persistent symptoms performed poorly in visual perception/analysis and information processing. Persistent post-concussive symptoms could affect athletes’ visual memory, perception/analysis, reaction time and information processing speed, thus precipitating them to further injuries should they return to play prematurely.Competing interestsNone.
