Background: Medical students should learn to critically evaluate research to inform future evidence-based practice. Participation in research and audit at medical school can help develop these skills whilst prompting interest in academic pursuits. Aims: We investigate medical student attitudes and participation in extracurricular research and audit focusing on their opportunities, obstacles, motivation and outcomes. Method: A 60-item questionnaire was distributed to final-year medical students graduating from the University of Nottingham Medical School in the United Kingdom. Results: A total of 238 questionnaires were returned (response rate 75%). Of these, 86% felt research or audit experience was useful for medical students. The main driver for involvement was curriculum vitae (CV) improvement (51%). Male students and those involved in extracurricular research were more likely to agree that this experience should influence selection into training programmes ( p ¼ 0.017, p ¼ 0.0036). Overall, 91 respondents (38%) had been involved in such activity with a mean number of projects undertaken of two (range one to four). Those interested in a surgical career were most likely to have undertaken projects (58%). Frequently cited obstacles to involvement were time constraints (74%) and a perceived lack of interest from potential supervisors (63%). Conclusions: Despite significant CV motivation, many are enthusiastic regarding extracurricular research opportunities but frustrated by obstacles faced. Our study suggests there is scope for providing further opportunities to participate in such activities at medical school.

ObjectivesExternal ventricular drain (EVD) insertion is a common neurosurgical procedure. EVD-related infection (ERI) is a major complication that can lead to morbidity and mortality. In this study, we aimed to establish a national ERI rate in the UK and Ireland and determine key factors influencing the infection risk.MethodsA prospective multicentre cohort study of EVD insertions in 21 neurosurgical units was performed over 6 months. The primary outcome measure was 30-day ERI. A Cox regression model was used for multivariate analysis to calculate HR.ResultsA total of 495 EVD catheters were inserted into 452 patients with EVDs remaining in situ for 4700 days (median 8 days; IQR 4–13). Of the catheters inserted, 188 (38%) were antibiotic-impregnated, 161 (32.5%) were plain and 146 (29.5%) were silver-bearing. A total of 46 ERIs occurred giving an infection risk of 9.3%. Cox regression analysis demonstrated that factors independently associated with increased infection risk included duration of EVD placement for ≥8 days (HR=2.47 (1.12–5.45); p=0.03), regular sampling (daily sampling (HR=4.73 (1.28–17.42), p=0.02) and alternate day sampling (HR=5.28 (2.25–12.38); p<0.01). There was no association between catheter type or tunnelling distance and ERI.ConclusionsIn the UK and Ireland, the ERI rate was 9.3% during the study period. The study demonstrated that EVDs left in situ for ≥8 days and those sampled more frequently were associated with a higher risk of infection. Importantly, the study showed no significant difference in ERI risk between different catheter types.
Background: Artificial Intelligence (AI) may favorably support surgeons but may result in concern among patients and their relatives.Objective: To evaluate attitudes of patients and their relatives towards the use of AI in neurosurgery.Methods: In this two-stage cross-sectional survey, a qualitative survey was administered to a focus group of former patients to investigate their perception of AI and its role in neurosurgery. Five themes were identified and used to generate a case-based quantitative survey administered to inpatients and their relatives over a two-week period. Presented AI platforms were rated appropriate and acceptable using 5-point Likert scales. Demographic data was collected. A Chi Square test was performed to determine whether demographics influenced participants' attitudes.Results: In the first stage, 20 participants responded. Five themes were identified: interpretation of imaging (4/20; 20%), operative planning (5/20; 25%), real-time alert of potential complications (10/20; 50%), partially autonomous surgery (6/20; 30%), fully autonomous surgery (3/20; 15%). In the second stage, 107 participants responded. The majority felt appropriate and acceptable to use AI for imaging interpretation (76.7%; 66.3%), operative planning (76.7%; 75.8%), real-time alert of potential complications (82.2%; 72.9%), and partially autonomous surgery (58%; 47.7%). Conversely, most did not feel that fully autonomous surgery was appropriate (27.1%) or acceptable (17.7%). Demographics did not have a significant influence on perception. Conclusions:The majority of patients and their relatives believed that AI has a role in neurosurgery and found it acceptable. Notable exceptions remain fully autonomous systems, with most wanting the neurosurgeon ultimately to remain in control.
Traumatic brain injury (TBI) is a leading cause of death and disability worldwide and is a risk factor for dementia later in life. Research into the pathophysiology of TBI has focused on the impact of injury on the neuron. However, recent advances have shown that TBI has a major impact on synapse structure and function through a combination of the immediate mechanical insult and the ensuing secondary injury processes, leading to synapse loss. In this review, we highlight the role of the synapse in TBI pathophysiology with a focus on the confluence of multiple secondary injury processes including excitotoxicity, inflammation and oxidative stress. The primary insult triggers a cascade of events in each of these secondary processes and we discuss the complex interplay that occurs at the synapse. We also examine how the synapse is impacted by traumatic axonal injury and the role it may play in the spread of tau after TBI. We propose that astrocytes play a crucial role by mediating both synapse loss and recovery. Finally, we highlight recent developments in the field including synapse molecular imaging, fluid biomarkers and therapeutics. In particular, we discuss advances in our understanding of synapse diversity and suggest that the new technology of synaptome mapping may prove useful in identifying synapses that are vulnerable or resistant to TBI.
IntroductionCauda equina syndrome (CES) is a potentially devastating condition caused by compression of the cauda equina nerve roots. This can result in bowel, bladder and sexual dysfunction plus lower limb weakness, numbness and pain. CES occurs infrequently, but has serious potential morbidity and medicolegal consequences. This study aims to identify and describe the presentation and management of patients with CES in the UK.Methods and analysisUnderstanding Cauda Equina Syndrome (UCES) is a prospective and collaborative multicentre cohort study of adult patients with confirmed CES managed at specialist spinal centres in the UK. Participants will be identified using neurosurgical and orthopaedic trainee networks to screen referrals to spinal centres. Details of presentation, investigations, management and service usage will be recorded. Both patient-reported and clinician-reported outcome measures will be assessed for 1 year after surgery. This will establish the incidence of CES, current investigation and management practices, and adherence to national standards of care. Outcomes will be stratified by clinical presentation and patient management. Accurate and up to date information about the presentation, management and outcome of patients with CES will inform standards of service design and delivery for this important but infrequent condition.Ethics and disseminationUCES received a favourable ethical opinion from the South East Scotland Research Ethics Committee 02 (Reference: 18/SS/0047; IRAS ID: 233515). All spinal centres managing patients with CES in the UK will be encouraged to participate in UCES. Study results will be published in medical journals and shared with local participating sites.Trial registration number ISRCTN16828522; Pre-results.
ObjectivesTo analyse the research activity and publication output of surgical trainee research collaboratives in the UK.SettingSurgical trainee research collaboratives in the UK.ParticipantsA total of 24 collaboratives were included in this study from 33 identified organisations. We excluded one group that focused purely on systematic review of the literature and eight groups for which we could not identify suitable data sources (website or trainee committee contact).Primary and secondary outcomePrimary data-points were identified for each collaborative including surgical subspeciality, numbers and types of projects. For published articles, secondary outcomes including study population size, journal impact factor, number of citations and evidence level were collected.ResultsA total of 24 collaboratives met our inclusion criteria with a portfolio of 80 projects. The project types included audit (46%), randomised clinical trial (16%), surveys (16%), cohort studies (10%), systematic reviews (2.5%) and other or unidentifiable (9.5%). A total of 35 publications were identified of which just over half (54%) were original research articles. The median size of studied population was 540 patients with a range from 108 to 3138. The published works provided a varied compilation of evidence levels ranging from 1b (individual RCT) to 5 (expert opinion) with a median level of 2b (individual cohort study). The West Midlands Research Collaborative had the highest number of publications (13), citations (130) and h-index (5).ConclusionsThe experience of UK-based trainee research collaboratives provides useful insights for trainees and policymakers in global healthcare systems on the value and feasibility of trainee-driven high quality surgical research.
