From data to practice: brain meningioma treatment in elderly patients – a survey of the Italian Society of Neurosurgery (SINch®) and systematic review and meta-analysis

The management of meningioma in elderly patients (MEP) presents a complex and evolving challenge. Data available offer conflicting information on treatment options and complications. This survey aimed to examine the current approach to MEP, comparing the national profile to data in the current literature. A survey addressing the treatments options and management of meningioma in elderly was designed on behalf of SINch® (Società Italiana di Neurochirurgia) and sent via email to all Chiefs of Neurosurgical Departments. The survey remained open for responses from May 5th, 2022, until November 21st, 2022. A search of the literature published between January 2000 and March 2023, in accordance to PRISMA guidelines, was included. A total of 51 Neurosurgical centers participated in the survey. The caseload profile of each center influences the choice of treatment selection (Stereotactic Radiosurgery versus open surgery) (p = 0.01) and the consolidated practice of discussing cases within a multidisciplinary group (p = 0.02). The pooled meta-analysis demonstrated a significant increased risk in the elderly group for permanent deficits (p < 0.00001), postoperative infections (p = 0.0004) and hemorrhage (p = 0.0001), perioperative mortality (p < 0.00001), and medical complications (p < 0.00001) as compared to the young population. This study presents the initial comprehensive analysis of the existing trends in the surgical management of MEP in Italy. The significant variation in practices primarily stems from the absence of standardized guidelines. While most centers have adopted an integrated approach, there is a need to promote a multidisciplinary care model. Prospective studies are needed to gather robust evidence in this clinical setting.

Chinese expert consensus on implementation and management of brain-computer interface clinical research in neurological diseases

The development of brain-computer interface (BCI) technology and its preliminary research results show great clinical application prospects. In particular, the application of BCI technologyis a hot research topic in the field of nervous system diseases at present, but the current BCI technology is still in the stage of experimental exploration, needing systematic and standardized clinical research validation. For this purpose, the consensus is led by the Society of Neurosurgery of Chinese Medical Association and Society of Cerebrovascular Surgery of Chinese Stroke Association. Based on the in-depth discussion of multidisciplinary experts and the vote of the Delphi Method, the guidelines and principles are proposed for pre-clinical qualification review, clinical research implementation and management, and long-term effect tracking and evaluation, so as to standardize research ethics and clinical research procedures and further promote the extensive application and in-depth development of BCI technology in the treatment of nervous system diseases.

Interpretation of Chinese guideline for the clinical management of patients with ruptured intracranial aneurysms (2024)

Aneurysmal subarachnoid hemorrhage (aSAH) is a life-threatening neurological emergency with high mortality, and even patients receiving optimal medical care may develop long-term disability, which seriously affects their quality of life and increases the heavy medical burden on society and families. To provide comprehensive clinical management advice, the Society of Neurosurgery of the Chinese Medical Association, the Society of the Chinese Stroke Association of the National Medical Center for Neurological Diseases, and the National Clinical Research Center for Neurological Diseases jointly formulate "Chinese Guidelines for the Clinical Management of Patients With Ruptured Intracranial Aneurysms in 2024". The evidence sources are divided into the Chinese population and other populations, using a modular format to provide recommendations, summaries of relevant opinions, and future research directions on epidemiology, clinical imaging diagnosis, prognosis evaluation, treatment strategies and choices, anesthesia management, perioperative care, and recommendations for the management of aSAH in special populations. It provides practical clinical guidance and recommendations for doctors and related professionals.

Interpretation of Chinese guideline for the clinical management of patients with unruptured intracranial aneurysms (2024)

With the popularization of cerebrovascular imaging technology, the clinical detection rate of unruptured intracranial aneurysm (UIA) is increasing. UIA has a low risk of rupture, but once ruptured, it can seriously affect human health. The treatment of UIA is highly controversial and has attracted widespread clinical attention. The Society of Neurosurgery of the Chinese Medical Association, the Society of Cerebrovascular Surgery of the Chinese Stroke Association, the National Center for Neurological Diseases, and the National Center for Clinical Research on Neurological Diseases jointly formulate "Chinese guideline for the clinical management of patients with unruptured intracranial aneurysm management (2024)", which adopts a modular format, highlighting management recommendations and indicating current research deficiencies and future research directions. It provides comprehensive clinical management recommendations on UIA epidemiology, population screening, clinical imaging and diagnosis, rupture risk assessment, treatment decisions and choices, postoperative follow-up, and long-term management. The evidence sources are divided into the Chinese population and other populations, which helps guide clinical practice in China.

Burnout in Neurosurgery

Burnout is a pervasive psychosocial syndrome that manifests as a chronic response to interpersonal stressors encountered in the occupational setting. Neurosurgeons exhibit a high prevalence rate of burnout, ranging from 33% to 67%. The primary objective of this study is to examine the prevalence of Burnout syndrome within the neurosurgical community and identify the contributing factors. A prospective observational study was conducted utilizing an anonymous survey format, incorporating the Maslach Burnout Inventory-Human Services Survey (MBI-HSS) questionnaire. Additional inquiries were made regarding demographic characteristics, occupational factors, lifestyle choices, and the Hospital Anxiety and Depression Scale (HADS) questionnaire. The survey was disseminated between March 23rd, 2023, and April 4th, 2023, utilizing the email registries of the Spanish Society of Neurosurgery (SENEC) and the Latin American Federation of Neurosurgical Societies (FLANC). Descriptive analysis was performed, comparing responses between participants with and without burnout syndrome using cross-tabulation and the Chi-square test to assess the presence of dependency. A total of 282 neurosurgeons completed the survey. The sample comprised 30.1% females and 69.9% males, with a median age within the 30-40 range. Among the surveyed neurosurgeons, 66.7% exhibited a prevalence of burnout, while 23.4% met the criteria for defined burnout. Significantly higher rates of burnout syndrome were observed among residents, specifically those in their fifth year of residency, as well as those whose departments perform a moderate range of surgeries (500-1000), participating in on-call duties, lacking regular physical exercise (at least twice a week), engaging infrequently in social activities with friends, lacking extracurricular hobbies, and obtaining scores exceeding 10 points in any of the HADS subscales. Burnout syndrome affects nearly a quarter of the neurosurgical specialists included in this study. Moreover, a distinct profile associated with defined burnout among neurosurgeons emerges, encompassing characteristics such as being a fifth-year resident, belongs to departments with a moderate number of surgeries, with few extra-occupational distractions and exhibiting symptoms of depression or anxiety.

Chinese expert consensus on diagnosis and treatment of craniopharyngioma (2024)

Craniopharyngioma is a sellar tumor with benign pathology and malignant clinical manifestations. Partial resection plus radiotherapy, internal radiation therapy and chemotherapy are the conventional treatment strategies forcraniopharyngioma in most hospitals, which cause many patients to lose the best time to cure and make reoperation more difficult after recurrence. Therefore, the Pediatric Group of Chinese Society of Neurosurgery, Chinese Medical Association organized domestic experts from Pediatrics, Pediatric Neurosurgery, Genetics and Endocrinology to reach a consensus on the following topics: pathological and molecular genetic classification of craniopharyngioma, basic principles of curing tumors, surgical classification of tumors, surgical approach, perioperative and long-term treatment plan. This is expected to improve the quality of life and prognosis of patients, and further standardize the diagnosis and treatment of craniopharyngioma.

The impact of SARS-Covid-19 pandemic on peripheral nerve surgery – A single centre report

ObjectiveSARS-Cov-19 pandemic totally changed daily routine work in German hospitals. As hospital capacity was reduced, many surgeries were postponed or even cancelled. On March 25th 2020 the German Society of Neurosurgery (DGNC) published a statement in which urgent non-elective surgeries were defined for each neurosurgical domain, whereas elective interventions were deferred. The present work examines the impact of these Covid strategies focusing on patients with peripheral lesions who were conducted to our department during this period of time. MethodsAll patients who underwent any peripheral nerve surgery at our department from January 2018 until December 2022, were included. The complete range of surgeries including peripheral nerve lesions was examined encompassing compression syndromes, traumatic lesions of brachial plexus, traumatic lesions and tumors of single peripheral nerves. The numbers of surgical procedures were compared before, during and after pandemic. Pearson correlation coefficient was analysed. ResultsFrom 2018 to 2022 the total number of surgical procedures involving peripheral nerves included 2422 procedures. Compression syndromes made up the largest proportion (1433 operations, 59%), followed by peripheral nerve lesions (445 operations, 18%), peripheral nerve tumors (344 operations, 14%) and lesions of the brachial plexus (142 operations, 6%). The average was 40,5 interventions per month, the range was 7–63. Two declines in the number of peripheral nerve surgeries were noted during this period. The first was in April and May 2020 with an average drop of 65% and 41% respectively. In these months the average number of operations was 37. The second decrease was from October 2021 until January 2022, where number of surgeries was reduced by 16%, 36%, 83% and 18% with an average number of 50 operations. Both declines showed a significant and strong correlation with the lower number of compression syndrome treatments (r = 0.952, p < 0.001 and r = 0.968, p < 0.001), while no drop and no significant correlation was found in the treatment of traumatic peripheral nerve injuries (p = 0.769, r = 0.095 and p = 0.243, r = 0.366) and traumatic brachial plexus injuries (p = 0.787, r = 0.088 and p = 0.780, r = 0.09). A weak significant correlation was seen in the treatment numbers of peripheral nerve tumors (p = 0.017, r = 0.672 and p = 0.015, r = 0.67). ConclusionCovid-19 pandemic lead to a significant decrease in the number of nerve decompressions, since, according to the German Society of Neurosurgery, those were considered as elective surgeries.

Mapping the global neurosurgery workforce. Part 1: Consultant neurosurgeon density

OBJECTIVE It is unknown whether efforts to expand access to neurosurgery worldwide have translated to an increase in the global neurosurgery workforce, particularly in low- and middle-income countries. The main objective of this study was to quantify the number and distribution of consultant neurosurgeons worldwide, while also identifying temporal and geographic trends in the neurosurgery workforce in different income levels and WHO regions, and analyzing what factors might contribute to the growth of a national workforce. METHODS This study was a subanalysis of an electronic cross-sectional survey administered to participants identified through neurosurgery societies, personal contacts, and online searches of all 193 countries and 26 territories, independent states, and disputed regions as defined by the World Bank (WB) and United Nations between October 2022 and March 2023. Population-weighted statistics for the consultant neurosurgery workforce and resource availability were estimated, and linear regression analysis was conducted to identify correlations with growth in the workforce. RESULTS Data were obtained for 192 countries (99.5%) and 25 additional territories, states, and disputed regions (96.2%). One hundred seventy-seven respondents participated in the survey. There were an estimated 72,967 neurosurgeons worldwide, representing a global pooled density of 0.93 neurosurgeons per 100,000 people and a median country density of 0.44 neurosurgeons per 100,000 people. The authors found an increasing density of consultant neurosurgeons, from low-income countries (0.12 per 100,000 people), to lower-middle-income countries (LoMICs; 0.37), to upper-middle-income countries (UpMICs; 1.13), and to high-income countries (2.44). The WHO African and Southeast Asia regions had the lowest pooled neurosurgeon density, while the Western Pacific region (WPR) had the highest density. There were 29 countries, 14 territories, and 1 independent state with no neurosurgeons. Neurosurgeons in countries with higher income–level designations had more frequent access to resources and equipment. The annual growth rates in workforce density were highest in LoMICs (26.0%) and UpMICs (21.3%), and the most rapid annual growth was in the Southeast Asia region (33.0%). Regression analysis revealed that an increasing population quartile, the Eastern Mediterranean region (relative to the WPR), the presence of a national neurosurgery society, increasing global development aid, and national gross domestic product were associated with relative growth in national neurosurgeon density. CONCLUSIONS The authors estimate a global consultant neurosurgeon workforce of nearly 73,000 neurosurgeons, with stark disparities in the density and growth of the workforce in different WB income-level groups and WHO regions. The presence of a neurosurgery society was correlated with the growth of the workforce, and this study identified several regional targets for further intervention to expand access to neurosurgery.

The “state of the art” of intraoperative neurophysiological monitoring: An Italian neurosurgical survey

IntroductionIntraoperative Neurophysiological Monitoring (IOM) is widely used in neurosurgery but specific guidelines are lacking. Therefore, we can assume differences in IOM application between Neurosurgical centers. Research questionThe section of Functional Neurosurgery of the Italian Society of Neurosurgery realized a survey aiming to obtain general data on the current practice of IOM in Italy. Materials and methodsA 22-item questionnaire was designed focusing on: volume procedures, indications, awake surgery, experience, organization and equipe. The questionnaire has been sent to Italian Neurosurgery centers. ResultsA total of 54 centers completed the survey. The annual volume of surgeries range from 300 to 2000, and IOM is used in 10–20% of the procedures. In 46% of the cases is a neurologist or a neurophysiologist who performs IOM. For supra-tentorial pathology, almost all perform MEPs (94%) SSEPs (89%), direct cortical stimulation (85%). All centers perform IOM in spinal surgery and 95% in posterior fossa surgery. Among the 50% that perform peripheral nerve surgery, all use IOM. Awake surgery is performed by 70% of centers. The neurosurgeon is the only responsible for IOM in 35% of centers. In 83% of cases IOM implementation is adequate to the request. Discussion and conclusionsThe Italian Neurosurgical centers perform IOM with high level of specialization, but differences exist in organization, techniques, and expertise. Our survey provides a snapshot of the state of the art in Italy and it could be a starting point to implement a consensus on the practice of IOM.

Mapping the global neurosurgery workforce. Part 2: Trainee density

OBJECTIVE A sustainable neurosurgery workforce depends on robust training pipelines, but the size and distribution of the global neurosurgery trainee workforce has not been described. The objective of this study was to identify the types of training programs that exist in the global neurosurgery workforce, the support that trainees receive, the diversity of trainee experiences, and the accreditation processes that exist to regulate training programs. METHODS This study was a subanalysis of a cross-sectional survey administered online in all 193 countries and 26 territories, independent states, and disputed regions as defined by the World Bank and United Nations. Participants were identified through neurosurgery society leadership, the personal contacts of the coauthors, and bibliometric and search engine searches. Population-weighted statistics were constructed and segregated by country income level and WHO regions. RESULTS Data were obtained for 187 countries (96.9%) and 25 additional territories, states, and disputed regions (96.2%). There were an estimated 1261 training programs and 10,546 trainees within the regions sampled, representing a global pooled density of 0.14 neurosurgery trainees per 100,000 people and a median national density of 0.06 trainees per 100,000 people. There was a higher density in high-income countries (HICs; 0.48 trainees per 100,000 people) compared with upper-middle-income countries (0.09 per 100,000), lower-middle-income countries (0.06 per 100,000), and low-income countries (LICs; 0.07 per 100,000). The WHO European (0.36 per 100,000) and Americas (0.27 per 100,000) regions had the highest trainee densities, while the Southeast Asia (0.04 per 100,000) and African (0.05 per 100,000) regions had the lowest densities. Among countries with training programs, LICs had the poorest availability of subspecialty training and resources such as cadaver laboratories and conference stipends for trainees. Training program accreditation processes were more common in HICs (81.8%) than in low- and middle-income countries (LMICs; 69.2%) with training programs. CONCLUSIONS The authors estimate that there are at least 1261 neurosurgery training programs with 10,546 total trainees worldwide. The density of neurosurgery trainees was disproportionately higher in HICs than LMICs, and the WHO European and Americas regions had the highest trainee densities. The trainee workforce in LICs had the poorest access to subspecialty training and advanced resources.

NCOG-26. CORE OUTCOME SETS FOR USE IN FUTURE MENINGIOMA CLINICAL STUDIES: RESULTS OF THE COSMIC PROJECT

Abstract OBJECTIVE Core Outcome Sets (COS) define the minimum outcomes that should be measured and reported in all clinical trials for a specific health condition or health area. The aim was to develop two COS for intracranial meningioma; one for clinical trials (COSMIC: Intervention) and one for observational studies (COSMIC: Observation). METHODS A study advisory group was formed with representation from international stakeholders of charities (IBTA, TBTC, brainstust), neurosurgery societies (SBNS, BIMS) and neuro-oncology societies (BNOS, EANO, EORTC, ICOM, RANO-PRO, SNO). Two systematic literature reviews and trial registry searches were performed to identify outcomes reported in published and ongoing 1) meningioma clinical trials, and 2) studies of incidental/untreated meningioma. Outcomes were deduplicated and categorised. Individuals were recruited from stakeholder groups (including meningioma patients and carers, healthcare professionals, researchers) to participate in 2-round, international, modified eDelphi surveys. The final core outcome sets were ratified through online consensus meetings. RESULTS The COSMIC: Intervention systematic review identified 660 verbatim outcomes, rationalized into 24 Delphi survey items. Following the consensus meeting, 15 outcomes were included in the final set. For COSMIC: Observation, 267 verbatim outcomes were identified and rationalized into 17 Delphi survey items. 16 outcomes were included in the final set. There were eight core outcomes common to both COSMIC: Intervention and COSMIC: Observation COS, namely tumour growth, physical, emotional, and neurocognitive functioning, overall quality of life, progression-free survival, meningioma specific mortality and overall survival. Role and social functioning were core outcomes in COSMIC Observation but not COSMIC intervention. CONCLUSIONS The COSMIC study has defined the core outcome sets for use in future meningioma clinical trials and studies. Role and social functioning were important to incidental meningioma patients and likely reflects the anxiety and uncertainty around clinical treatment. International stakeholder agreement should ensure widespread use and adoption.

Indications for surgical evacuation of cerebellar intracerebral hemorrhage: consensus guidelines from the French Society of Neurosurgery (SFNC) and the French Society of Vascular Neurology (SFNV)

BackgroundCerebellar intracerebral hemorrhage (ICH) is associated with poor functional prognosis and high mortality. Surgical evacuation has been proposed to improve outcome. The purpose of this review was to determine the benefit of surgical evacuation of cerebellar ICH and to establish guidelines for when it should be performed. MethodThe writing committee comprised 9 members of the SFNV and the SFNC. Recommendations were established based on a literature review using the PICO questions. The American Heart Association (AHA) classification was used to define recommendation level. In case of insufficient evidence, expert opinions were provided. ResultsLevels of evidence were low to moderate, precluding definitive recommendations. Based on available data, surgical hematoma evacuation is not recommended to improve functional outcome (Class III; Level B NR). However, based on subgroup analysis, surgical evacuation may be considered in strictly selected patients (Class IIb; Level C-EO): hematoma volume 15−25 cm3, GCS 6-10, and no oral anticoagulation or antiplatelet therapy. Moreover, surgical evacuation is recommended to decrease risk of death (Class IIa; Level B NR) in patients with a hematoma volume >15 cm3 and GCS score <10. ConclusionThese guidelines were based on observational studies, limiting the level of evidence. However, except for strictly selected patients, surgical evacuation of cerebellar ICH was not associated with improved functional outcome, limiting indications. Data from RCTs are needed in this field.

Executive summary of the expert consensus document from the Spanish Society of Neurosurgery and the Spanish Society of Endocrinology and Nutrition: Clinical recommendations on the perioperative management of pituitary tumors

Pituitary tumors (PT) account for 15% of intracranial tumors affect 10.7%–14.4% of the population although the incidence of clinically relevant PT is 5.1 cases/100,000 inhabitants. Surgical treatment is indicated in PTs with hormone hypersecretion (except for prolactin-producing PTs) and those with local compressive or global neurological symptoms. Multidisciplinary care, is essential for patients with PTs, preferably delivered in a center of excellence and based on a well-defined care protocol. In order to facilitate and standardize the clinical procedures for this type of tumor, this document gathers the positioning of the Neuroendocrinology Knowledge Area of the Spanish Society of Endocrinology and Nutrition (SEEN) and the Spanish Society of Neurosurgery (SENEC) on the management of patients with PTs and their preoperative, surgical and postoperative follow-up.

Women in neurosurgery in Peru: current situation and representation

The participation of women in neurosurgery in Peru began in 1974 with the first Peruvian female neurosurgeon, who was accepted into a residency program with the condition of not getting married during her training. Nowadays, the conditions are more just, and there is greater equality of opportunities between men and women, but the numbers show that the differences have not yet been fully equalized. As evidence of this, it has been observed that only 17% of the residency positions offered in 2022 were filled by women, and there has been reduced participation of female neurosurgeons in the Peruvian Society of Neurosurgery. This article discusses the importance of tracking and promoting stories of Peruvian female neurosurgeons and calls for research in the area of women in neurosurgery in latin countries, like Peru.

Current State of Brazilian Neurosurgery: Evaluation of Burden of Care and Case Volume

Low- and middle-income countries (LMICs) bear a heavier burden of neurosurgical diseases than high-income countries. Brazil, a growing middle-income country, holds promise as a health care market. However, there exists a lack of information to characterize the state of neurosurgical practice and access to care in Brazil. This study aimed to characterize neurosurgical practice in Brazil and identify barriers to care. A collaborative survey was developed with Brazilian neurosurgeons and distributed by the Brazilian Society of Neurosurgery. The survey gathered demographic information, practice characteristics, case volume, referral patterns, income sources, and assessed barriers using a Likert scale. Descriptive statistics were employed for data analysis. One-hundred and forty-nine neurosurgeons participated (response rate: 17.5%), representing various states in Brazil. Neurosurgeons practiced in more than 4 different hospital systems on average, with most consultations and procedures occurring in public hospitals. Common procedures included tumor surgeries, general neurosurgery, spine surgeries, trauma surgeries, and hydrocephalus management. Equipment shortage and systemic issues were identified as major barriers to care. Neurosurgical practice in Brazil exhibits diverse age distribution, widespread distribution across states, and involvement in both public and private hospitals. Survey insights shed light on neurosurgical workload and neurosurgical practice characterization. Lack of equipment and inadequate postoperative resources pose significant barriers to care. The findings highlight the need for investments in equipment, critical care facilities, and improved health care system coordination to enhance access to neurosurgical care in Brazil.

What to report in sellar tumor MRI? A nationwide survey among German pituitary surgeons, radiation oncologists, and endocrinologists

PurposeWhile MRI has become the imaging modality of choice in the diagnosis of sellar tumors, no systematic attempt has yet been made to align radiological reporting of findings with the information needed by the various medical disciplines dealing with these patients. Therefore, we aimed to determine the prevailing preferences in this regard through a nationwide expert survey.MethodsFirst, an interdisciplinary literature-based catalog of potential reporting elements for sellar tumor MRI examinations was created. Subsequently, a web-based survey regarding the clinical relevance of these items was conducted among board certified members of the German Society of Neurosurgery, German Society of Radiation Oncology, and the Pituitary Working Group of the German Society of Endocrinology.ResultsA total of 95 experts (40 neurosurgeons, 28 radiation oncologists, and 27 endocrinologists) completed the survey. The description of the exact tumor location, size, and involvement of the anatomic structures adjacent to the sella turcica (optic chiasm, cavernous sinus, and skull base), occlusive hydrocephalus, relationship to the pituitary gland and infundibulum, and certain structural characteristics of the mass (cyst formation, hemorrhage, and necrosis) was rated most important (> 75% agreement). In contrast, the characterization of anatomic features of the nasal cavity and sphenoid sinus as well as the findings of advanced MRI techniques (e.g., perfusion and diffusion imaging) was considered relevant by less than 50% of respondents.ConclusionTo optimally address the information needs of the interdisciplinary treatment team, MRI reports of sellar masses should primarily focus on the accurate description of tumor location, size, internal structure, and involvement of adjacent anatomic compartments.
