RESUMO

Background Neurosurgery can be a daunting career choice for medical students, with preparation for trainee application often being inaccessible and expensive. This article describes a student-led neurosurgical skills event supported by local neurosurgery faculty members. Such event was designed to offer a means to bridge this gap by providing an opportunity to practice neurosurgical techniques in simulation, and learn about what a career in neurosurgery involves. Methods Pre- and postskills laboratory surveys were used to ascertain the baseline confidence and knowledge of common neurosurgical techniques, as well as to what both the application to neurosurgery and the typical workload of a neurosurgeon involves. The conference offered six neurosurgical workshops as well as three lectures to provide practical and theoretical learning opportunities. The session included introduction to the candidates and faculty, identification of learning objectives, and career discussion. Postcourse feedback also was also used to assess learning outcomes. Results Eighteen students attended the event. Postskills event, students were significantly more likely to understand the principles behind all of the relevant neurosurgical skills included on the day. Additionally, students were more likely to understand what a career in neurosurgery involves, and how to approach applying for a training number. Respondents enjoyed the workshops, valued hands-on experience and interactions with consultants, found it affordable, and would recommend to their peers. Conclusions For medical students interested in a career in neurosurgery, opportunities to learn relevant techniques and skills are often expensive and difficult to come across. Here, we highlight affordable methods of simulation to result in significant student satisfaction. Additionally, providing ample opportunity to practice different neurosurgical techniques under almost 1:1 level tutoring enables significant increases in students' confidence and understanding of different neurosurgical concepts. We greatly encourage other medical student groups to develop their own hands-on simulation events to attract medical students to a surgical field often considered daunting and inaccessible, and address gaps in the medical school curriculum.

RESUMO

BACKGROUND: Non-toxic approaches to enhance radiotherapy outcomes are beneficial, particularly in ageing populations. Based on preclinical findings showing that high-fibre diets sensitised bladder tumours to irradiation by modifying the gut microbiota, along with clinical evidence of prebiotics enhancing anti-cancer immunity, we hypothesised that dietary fibre and its gut microbiota modification can radiosensitise tumours via secretion of metabolites and/or immunomodulation. We investigated the efficacy of high-fibre diets combined with irradiation in immunoproficient C57BL/6 mice bearing bladder cancer flank allografts. RESULT: Psyllium plus inulin significantly decreased tumour size and delayed tumour growth following irradiation compared to 0.2% cellulose and raised intratumoural CD8+ cells. Post-irradiation, tumour control positively correlated with Lachnospiraceae family abundance. Psyllium plus resistant starch radiosensitised the tumours, positively correlating with Bacteroides genus abundance and increased caecal isoferulic acid levels, associated with a favourable response in terms of tumour control. Psyllium plus inulin mitigated the acute radiation injury caused by 14 Gy. Psyllium plus inulin increased caecal acetate, butyrate and propionate levels, and psyllium alone and psyllium plus resistant starch increased acetate levels. Human gut microbiota profiles at the phylum level were generally more like mouse 0.2% cellulose profiles than high fibre profiles. CONCLUSION: These supplements may be useful in combination with radiotherapy in patients with pelvic malignancy. Video Abstract.

RESUMO

BACKGROUND: Enhanced Recovery After Surgery (ERAS) is a well-established, protocol-driven, evidence-based approach to peri-operative care. ERAS protocols have been used to improve patient morbidity and mortality outcomes in various surgical specialties. More recently, it has been introduced to neurosurgery. Our aim was to establish an Enhanced Recovery After Cranial Surgery (ERACraS) protocol for patients as part of a quality improvement project (QIP) with the intention of reducing hospital length of stay (HLOS). METHODS: This QIP was carried out in the Department of Neurosciences (DCN), Edinburgh, over two four-month periods. A total of 40 patients over 18 years of age undergoing elective craniotomy surgery under a sole neurosurgeon were invited to take part in this QIP. Subsequently, data was retrospectively collected through our institution's online documentation system. RESULTS: 19 patients received conventional perioperative care (pre-ERACraS group) during December 2021-March 2022, and 21 received care according to the novel ERACraS (ERACraS group) during June-September 2022. Regarding supra-tentorial surgery, there was a reduction of 73% in HLOS in the ERACraS group. No change was observed in infra-tentorial surgery. Overall, the ERACraS protocol reduced HLOS by 50% in cranial surgery. CONCLUSION: The QIP data from ERACraS in our unit has shown that implementing ERAS protocols is feasible. A reduction in HLOS has implications for patient morbidity, mortality, and quality of care. We endeavour to collect long-term data by collaborating with neurosurgical units across the UK and Ireland to validate its feasibility and sustainability as part of a major QIP in neurosurgical practice. This can be potentially adopted by neurosurgical centres across the globe in a safe and sustained manner.

RESUMO

BACKGROUND: Meningiomas are one of the most common benign primary brain tumors; however, there is a paucity of literature on potential preventability. This comprehensive review aimed to explore the existing evidence for the potential risk factors that may contribute to meningioma development and to discuss early prevention strategies. METHODS: Literature search was conducted via MEDLINE, Embase, Web of Science, and Cochrane Database to retrieve existing literature on various environmental exposures and lifestyle behaviors that are potential risk factors for the development of meningiomas. RESULTS: Significant risk factors included exposure to ionizing radiation and certain environmental chemicals. Notably, this study also identified that cigarette smoking and obesity are associated with the development of meningiomas. To date, wireless phone usage, hormonal exposures, dietary factors, and traumatic brain injury remain inconclusive. Early prevention strategies should primarily be family-driven, community-based, and public health-endorsed strategies. Targeting unhealthy behaviors through healthcare organizations could execute a pivotal role in the maintenance of an optimum lifestyle, reducing the development of risk factors pertinent to meningiomas. CONCLUSIONS: To our knowledge, this is the first study that offers a perspective on prevention of meningiomas. A causal relationship of risk factors in developing meningiomas cannot be directly established with the current evidence. We are aware of the limitations of the hypothesis, but we believe that this study will raise more awareness and our findings could potentially be endorsed by organizations promoting health across the globe. Further prospective and retrospective studies will shed more light on this topic and help establish a definitive relationship.

RESUMO

OBJECTIVES: To assess the perception of global mentorship in neurosurgery among medical students across the world. Secondary aim included investigating the factors affecting the availability and benefits of providing global mentorship scheme in neurosurgery at a medical student level. SETTING: The Global Mentorship in Neurosurgery for Medical Students Study was a multinational cross-sectional audit that included medical students currently in the years 1-6 and intercalating programmes. They were invited to complete an online survey between 11 March and 1 May 2022. PARTICIPANTS: The survey was disseminated to 243 medical university ambassadors worldwide from 60 countries who distributed the survey within their respective medical student cohorts across the duration of the study. RESULTS: Overall, 2962 of 3017 (98.2%) responses from medical students from 60 countries worldwide were included; 1439 of 2962 (49%) and 1523 of 2962 (51%) were from years 1-3 and 4-6 medical students including intercalating degree programmes, respectively. 1712, 1502 and 1359 of responses gathered indicated that possible reasons for the lack of neurosurgical mentorship are lack of time and resources from trainees in neurosurgery, time within medical school's curriculum and awareness of societies in neurosurgery/neurology. 1276 and 1065 of medical students surveyed reported that it could also be due to lack of funding and overall inaccessibility within the area meaning there are few networking opportunities available. CONCLUSIONS: This pilot study indicates that there is a scope for improvement regarding the availability and accessibility of neurosurgical mentorship programmes worldwide at a medical student level. The evaluation suggested that medical students would most benefit from the neurosurgical mentorship in the future by means of increased numbers of mentors within their universities, accessibility to neurosurgical departments and the ability to choose mentorship globally via a unified digital platform.
