RESUMO

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.

RESUMO

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 recommendations for subspecialization within surgical neurooncology and advocate for care of these patients by specialists.

RESUMO

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.
