RESUMEN
BACKGROUND: Glioblastoma patients may develop functional deficits post-operatively that affect activities of daily living and result in worse outcomes. The Activity Measure for Post-Acute Care (AM-PAC) instrument assigns patients basic mobility and daily activity scores, but it is unknown if these scores correlate with post-operative outcomes in glioblastoma patients. METHODS: Adult (≥18 years) glioblastoma patients evaluated by physical/occupational therapy after resection at a single instution (June 2008-December 2020) were identified. Patient demographics, post-operative AM-PAC scores, and clinical outcomes were collected. Multivariate regression identified associations between AM-PAC scores and post-operative outcomes. RESULTS: 600 patients were included (mean age 59.3 years, 59.2 % male); 151 (25.3 %) and 246 (43.8 %) patients had low mobility (<42.9) and activity (<39.4) scores, respectively. 103 (17.2 %) and 177 (29.5 %) patients experienced extended lengths of stay (LOS) in the ICU (≥2 days) and overall (≥7 days), respectively. 154 (25.7 %) patients had non-home discharges. The 30-day readmission rate was 13.7 %. In multivariate analysis, low mobility scores correlated with increased odds of extended overall (p < 0.0001) and ICU (p = 0.0004) LOS, non-home discharge (p < 0.0001), and 30-day readmission (p = 0.0405). Low activity scores correlated with extended overall LOS (<0.0001) and non-home discharge (p < 0.0001). In log-rank analysis, median survival time was shorter for patients with low mobility (9.5 vs. 14.7 months, p < 0.0001) and activity (10.6 vs. 16.3 months, p < 0.0001) scores than for high-scoring patients. CONCLUSION: AM-PAC basic mobility and daily activity scores are associated with outcomes after glioblastoma resection. These easily obtainable scores may be useful for prognosticating and guiding decision making in post-operative glioblastoma patients.

OBJECTIVE: Patients with glioblastoma (GBM) often undergo surgery to prolong survival. However, the use of surgery, and more specifically achieving gross total resection (GTR), in patients >80 years old has yet to be fully assessed. Using the Surveillance, Epidemiology, and End Results (SEER) database, we aim to assess the efficacy of surgical resection, radiotherapy (RT) and chemotherapy (CT) on overall survival (OS) in very elderly GBM patients compared to elderly counterparts (age 65-79 years). METHODS: The SEER database was queried for all patients >65 years old with GBM (2000-2020). Patients not undergoing surgery or biopsy were excluded. Patients were stratified by age, and demographic relationships were assessed with chi-squared testing for categorical variables. Bivariable models were created using Kaplan-Meier survival estimates. All significant variables from bivariable analysis were included on multivariable Cox survival regression models to determine independent associations between clinical variables and OS. RESULTS: A total of 27,090 operative GBM patients were identified; 1868 patients (15.92â¯%) were very elderly and 10,092 patients (84.38â¯%) were elderly. Very elderly patients were less likely to undergo GTR (28â¯% vs 35â¯%, p<0.001), RT (59â¯% vs 78â¯%, p<0.001) and CT (40â¯% vs 66â¯%, p<0.001). In multivariable Cox regression analysis, very elderly patients who achieved GTR (HR=.696, p<0.001), received RT (HR=0.583, p<0.001) and underwent CT (HR=0.4197, p<0.001) had significantly improved OS compared to very elderly patients that did not undergo these treatment options. CONCLUSION: Currently, very elderly GBM patients undergo lower rates of aggressive surgery, RT and CT. However, very elderly patients that undergo surgery, RT and CT may have a survival advantage. These treatments should be considered as potential options for this patient population.
RESUMEN
BACKGROUND AND OBJECTIVES: Surgery for the very elderly is a progressively important paradigm as life expectancy continues to rise. Patients with glioblastoma multiforme often undergo surgery, radiotherapy (RT), and chemotherapy (CT) to prolong overall survival (OS). However, the efficacy of these treatment modalities in patients aged 80 years and older has yet to be fully assessed in the literature. METHODS: The National Cancer Database was used to retrospectively identify patients aged 65 years and older with glioblastoma multiforme (1989-2016). All available patient demographic characteristics, disease characteristics, and clinical outcomes were collected. To study OS, bivariable survival models were created using Kaplan-Meier estimates. A Cox proportional-hazards model was used for final adjusted analyses. RESULTS: A total of 578 very elderly patients (aged 80 years and older) and 2836 elderly patients (aged 65-79 years) were identified. Compared with elderly patients, very elderly patients were more likely to have Medicare (odds ratio [OR] 1.899 [95% CI: 1.417-2.544], P < .001) while less likely to have private insurance status (OR 0.544 [95% CI: 0.401-0.739], P < .001). In addition, very elderly patients were more likely to travel the least distance for treatment and have multiple tumors (P < .001). When controlling for demographic and disease characteristics, very elderly patients were less likely to receive gross total resection (GTR) (OR 0.822 [95% CI: 0.681-0.991], P < .041), RT (OR 0.385 [95% CI: 0.319-0.466], P < .001), or postoperative CT (OR 0.298 [95% CI: 0.219-0.359], P < .001) relative to elderly counterparts. Within very elderly patients, GTR, RT, and CT all independently and significantly predicted improved OS (P < .001 for all). These predictive models were deployed in an online calculator (https://spine.shinyapps.io/GBM_elderly). CONCLUSION: Very elderly patients are less likely to receive GTR, RT, or CT when compared with elderly counterparts despite use of these therapies conferring improved OS. Selected very elderly patients may benefit from more aggressive attempts at surgical and adjuvant treatment.
RESUMEN
OBJECTIVE: Chordomas are rare malignant bone tumors whose location in the skull base or spine, invasive surgical treatment, and accompanying adjuvant radiotherapy may all lead patients to experience poor quality of life (QOL). Limited research has been conducted on specific demographic and clinical factors associated with decreased QOL in chordoma survivors. Thus, the aim of the present study was to investigate several potential variables and their impact on specific QOL domains in these patients as well the frequencies of specific QOL challenges within these domains. METHODS: The Chordoma Foundation (CF) Survivorship Survey was electronically distributed to chordoma survivors subscribed to the CF Chordoma Connections forum. Survey questions assessed QOL in three domains: physical, emotional/cognitive, and social. The degree of impairment was assessed by grouping the participants into high- and low-challenge groups designated by having ≥ 5 or < 5 symptoms or challenges within a given QOL domain. Bivariate analysis of demographic and clinical characteristics between these groups was conducted using Fisher's exact test and the Mann-Whitney U-test. RESULTS: A total of 665 chordoma survivors at least partially completed the survey. On bivariate analysis, female sex was significantly associated with increased odds of significant emotional (p = 0.001) and social (p = 0.019) QOL burden. Younger survivors (age < 65 years) were significantly more likely to experience significant physical (p < 0.0001), emotional (p < 0.0001), and social (p < 0.0001) QOL burden. Skull base chordoma survivors had significantly higher emotional/cognitive QOL burden than spinal chordoma survivors (p = 0.022), while the converse was true for social QOL challenges (p = 0.0048). Survivors currently in treatment were significantly more likely to experience significant physical QOL challenges compared with survivors who completed their treatment > 10 years ago (p = 0.0074). Fear of cancer recurrence (FCR) was the most commonly reported emotional/cognitive QOL challenge (49.6%). Only 41% of the participants reported having their needs met for their physical QOL challenges as well as 25% for emotional/cognitive and 18% for social. CONCLUSIONS: The authors' findings suggest that younger survivors, female survivors, and survivors currently undergoing treatment for chordoma are at high risk for adverse QOL outcomes. Additionally, although nearly half of the participants reported a FCR, very few reported having adequate emotional/cognitive care. These findings may be useful in identifying specific groups of chordoma survivors vulnerable to QOL challenges and bring to light the need to expand care to meet the QOL needs for these patients.

BACKGROUND: Socioeconomic status (SES) is a major determinant of quality of life and outcomes. However, SES remains difficult to measure comprehensively. Distress communities index (DCI), a composite of 7 socioeconomic factors, has been increasingly recognized for its correlation with poor outcomes. As a result, the objective of the present study is to determine the predictive value of the DCI on outcomes following intracranial tumor surgery. METHODS: A single institution, retrospective review was conducted to identify adult intracranial tumor patients undergoing resection (2016-2021). Patient ZIP codes were matched to DCI and stratified by DCI quartiles (low:0-24.9, low-intermediate:25-49.9, intermediate-high:50-74.9, high:75-100). Univariate followed by multivariate regressions assessed the effects of DCI on postoperative outcomes. Receiver operating curves were generated for significant outcomes. RESULTS: A total of 2389 patients were included: 1015 patients (42.5%) resided in low distress communities, 689 (28.8%) in low-intermediate distress communities, 445 (18.6%) in intermediate-high distress communities, and 240 (10.0%) in high distress communities. On multivariate analysis, risk of fracture (adjusted odds ratio = 1.60, 95% confidence interval 1.26-2.05, P < 0.001) and 90-day mortality (adjusted odds ratio = 1.58, 95% confidence interval 1.21-2.06, P < 0.001) increased with increasing DCI quartile. Good predictive accuracy was observed for both models, with receiver operating curves of 0.746 (95% CI 0.720-0.766) for fracture and 0.743 (95% CI 0.714-0.772) for 90-day mortality. CONCLUSIONS: Intracranial tumor patients from distressed communities are at increased risk for adverse events and death in the postoperative period. DCI may be a useful, holistic measure of SES that can help risk stratifying patients and should be considered when building healthcare pathways.

OBJECTIVE: Factors that may drive recommendations for operative intervention for patients with intramedullary spinal cord tumors (ISCTs) have yet to be extensively studied. The authors investigated racial and socioeconomic disparities in the management of patients with primary spinal cord ependymomas and nonependymal gliomas, with the aim of determining the associations between socioeconomic patient characteristics, survival, and recommendations for the resection of primary ISCTs. METHODS: The Surveillance, Epidemiology, and End Results registry was queried to identify all patients > 18 years of age with ISCTs diagnosed between 2000 and 2019. Univariable and multivariable logistic regression analyses were used to calculate odds ratios for variables associated with receiving a surgical recommendation. Log-rank tests and multivariable Cox proportional hazards models were used to investigate overall survival (OS) and disease-specific survival (DSS). RESULTS: The authors identified 2325 patients (mean age 49 [SD 16] years; 48.8% female; 67.4% non-Hispanic White, 7.8% non-Hispanic Black, 16.2% Hispanic, 6.5% Asian/Pacific Islander, 0.6% Native American; 56.7% married; 64.4% with household income < $75,000; 73.8% with spinal ependymoma; and 26.2% with nonependymal spinal glioma). Eighty-seven percent of patients received a surgical recommendation. In multivariable models, marriage was associated with higher odds of receiving a surgical recommendation for ependymomas (OR 1.80, p = 0.005). In multivariable models for nonependymal spinal gliomas, older age (OR 0.98, p = 0.001) and increased number of tumors (OR 0.62, p = 0.015) were associated with decreased odds of receiving surgical recommendations. Among ependymomas, marriage (HR 0.59, p = 0.001), younger age (HR 0.93, p < 0.001), female sex (HR 0.43, p = 0.006), and decreased number of tumors (HR 0.56, p < 0.001) were associated with improved OS. Among nonependymal spinal gliomas, median household income ≥ $75,000 (HR 0.69, p = 0.020) and younger age (HR 0.98, p < 0.001) were associated with improved DSS, while Black race (HR 4.65, p = 0.027) and older age (HR 1.05, p < 0.001) were associated with worse OS. CONCLUSIONS: In patients with spinal ependymomas and nonependymal spinal gliomas, recommendations for surgery appear to be unaffected by patient sex, race, or income. Survival disparities appear to exist among unmarried, male, Black, and lower-income cohorts. Continued initiatives to identify drivers of disparities while improving health equity in this patient population are needed.

BACKGROUND: Patient-reported outcome measures (PROMs) are increasingly used to assess patients' perioperative health. The PROM Information System 29 (PROMIS-29) is a well-validated global health assessment instrument for patient physical health, though its utility in cranial neurosurgery is unclear. OBJECTIVE: To investigate the utility of preoperative PROMIS-29 physical health (PH) summary scores in predicting postoperative outcomes in brain tumor patients. METHODS: Adult brain tumor patients undergoing resection at a single institution (January 2018-December 2021) were identified and prospectively received PROMIS-29 surveys during pre-operative visits. PH summary scores were constructed and optimum prediction thresholds for length of stay (LOS), discharge disposition (DD), and 30-day readmission were approximated by finding the Youden index of the associated receiver operating characteristic curves. Bivariate analyses were used to study the distribution of low (z-score≤-1) versus high (z-score>-1) PH scores according to baseline characteristics. Logistic regression models quantified the association between preoperative PH summary scores and post-operative outcomes. RESULTS: A total of 157 brain tumor patients were identified (mean age 55.4±15.4 years; 58.0% female; mean PH score 45.5+10.5). Outcomes included prolonged LOS (24.8%), non-routine discharge disposition (37.6%), and 30-day readmission (19.1%). On bivariate analysis, patients with low PH scores were significantly more likely to be diagnosed with a high-grade tumor (69.6% vs 38.85%, p=0.010) and less likely to have elective surgery (34.8% vs 70.9%, p=0.002). Low PH score was associated with prolonged LOS (26.1% vs 22%, p<0.001), nonroutine discharge (73.9% vs 31.3%, p<0.001) and 30-day readmission (43.5% vs 14.9%, p=0.003). In multivariate analysis, low PH scores predicted greater LOS (odds ratio [OR]=6.09, p=0.003), nonroutine discharge (OR=4.25, p=0.020), and 30-day readmission (OR=3.93, p=0.020). CONCLUSION: The PROMIS-29 PH summary score predicts short-term postoperative outcomes in brain tumor patients and may be incorporated into prospective clinical workflows.

OBJECTIVE: The Hospital Frailty Risk Score (HFRS) is a recently developed tool that uses ICD-10 codes to measure patient frailty. However, the effectiveness of HFRS has not yet been assessed in meningioma patients specifically. The present study aimed to evaluate the effectiveness of HFRS in predicting surgical outcomes for patients with meningiomas. METHODS: This retrospective study utilized data from patients undergoing meningioma resection at a single institution (2017-2019). Data were obtained through a combination of automated data retrieval and manual chart review. Bivariate logistic regression was used to assess the prognostic ability of several frailty indices for predicting postoperative outcomes. Further, discrimination for each model was assessed using the area under the receiver operating characteristic curve (AUROC). Generalized linear models with gamma error distributions and a log-link function were used to model hospital length of stay (LOS), total charges, complications, and disposition. RESULTS: A total of 464 meningioma patients (mean age 58.20 years, 72.8 % female, 66.4 % white) were included. HFRS had a significantly greater AUROC when compared to ASA (p = 0.0074) for postoperative complications, and HFRS significantly outperformed ASA (p = 0.0021) and mFI-5 (p = 0.018) when predicting nonroutine discharge. On multivariate analysis, increasing HFRS scores were significantly and independently associated with greater LOS (p < 0.0001), higher hospital charges (p < 0.0001), higher odds of postoperative complications (OR = 1.05, p = 0.019), and nonroutine discharge (OR = 1.12, p < 0.0001). The HFRS was non-inferior compared to the mFI-5, CCI, ASA and mFI-11 in terms of model discrimination. CONCLUSION: HFRS effectively predicts postoperative outcomes for meningiomas and outperforms other indices in predicting complications and nonroutine discharge. This novel index may be used to improve clinical decision-making and reduce adverse postoperative outcomes among meningioma patients.

OBJECTIVE: The Hospital Frailty Risk Score (HFRS) is a tool for quantifying patient frailty using International Classification of Diseases, Tenth Revision codes. This study aimed to determine the utility of the HFRS in predicting surgical outcomes after resection of glioblastoma (GBM) and compare its prognostic ability with other validated indices such as American Society of Anesthesiologists score and Charlson Comorbidity Index. METHODS: A retrospective analysis was conducted using a GBM patient database (2017-2019) at a single institution. HFRS was calculated using International Classification of Diseases, Tenth Revision codes. Bivariate logistic regression was used to model prognostic ability of each frailty index, and model discrimination was assessed using area under the receiver operating characteristic curve. Multivariate linear and logistic regression models were used to assess for significant associations between HFRS and continuous and binary postoperative outcomes, respectively. RESULTS: The study included 263 patients with GBM. The HFRS had a significantly greater area under the receiver operating characteristic curve compared with American Society of Anesthesiologists score (P = 0.016) and Charlson Comorbidity Index (P = 0.037) for predicting 30-day readmission. On multivariate analysis, the HFRS was significantly and independently associated with hospital length of stay (P = 0.0038), nonroutine discharge (P = 0.018), and 30-day readmission (P = 0.0051). CONCLUSIONS: The HFRS has utility in predicting postoperative outcomes for patients with GBM and more effectively predicts 30-day readmission than other frailty indices. The HFRS may be used as a tool for optimizing clinical decision making to reduce adverse postoperative outcomes in patients with GBM.

OBJECTIVE: Antifibrinolytics, such as tranexamic acid (TXA), have been shown to decrease intraoperative blood loss across multiple surgical disciplines. However, they carry the theoretical risk of thromboembolic events secondary to induced hypercoagulability. Therefore, the aim of this study was to systematically review the available literature and perform a meta-analysis on the use of TXA in meningioma resection to assess thromboembolic risks. METHODS: The PubMed, Web of Science, and Google Scholar databases were reviewed for all randomized controlled trials presenting primary data on TXA use during resection of intracranial meningiomas. Data were gathered on operative duration, venous thromboembolic complications, deep venous thrombosis, use of allogeneic blood transfusion, estimated blood loss (EBL), and postoperative hemoglobin. Patients who received TXA were compared with controls who did not receive TXA intraoperatively using random-effects models. RESULTS: A total of 508 unique articles were identified, of which 493 underwent full-text review. Ultimately, 6 studies with 381 total patients (190 receiving TXA) were included in the final analysis. All 6 trials were randomized, blinded, and placebo controlled with a TXA administration rate of a 20-mg/kg load followed by a 1-mg/kg/hr infusion. All studies were performed in lower-middle-income countries. There were no reported instances of venous thromboembolism (VTE) in the TXA and non-TXA cohorts. Patients receiving TXA exhibited fewer allogeneic transfusions (21.5% vs 41.6% [OR 0.26, 95% CI 0.09-0.77], p = 0.02) and lower EBL (MD -282.48 mL [95% CI -367.77 to -197.20 mL], p < 0.001) compared with patients who did not receive TXA, and they also had lower rates of perioperative complications (10.7% vs 19.9% [OR 0.47, 95% CI 0.2-0.95], p = 0.04). CONCLUSIONS: Current literature suggests that TXA is not associated with increased risk for VTE when administered during resection of intracranial meningioma. TXA appears to decrease intraoperative blood loss and allogeneic transfusion requirements during meningioma resection and thus may improve the safety of surgical management of this pathology.

OBJECTIVE: There is a growing body of evidence demonstrating improved outcomes for patients with CNS neoplasms treated at academic centers (ACs) versus nonacademic centers (non-ACs), which represents a potential healthcare disparity within neurosurgery. In this paper, the authors sought to investigate the relationship between facility type and surgical outcomes in meningioma patients. METHODS: The National Cancer Database was queried for adult patients diagnosed with intracranial meningioma between 2004 and 2019. Patients were stratified by facility type, and the Mann-Whitney U-test and Fisher exact test were used for bivariate comparisons of continuous and categorical variables, respectively. Multivariate logistic regression was used to assess whether demographic variables were associated with treatment at ACs. Furthermore, multivariate Cox proportional hazards models were used to determine whether facility type was associated with overall survival (OS) outcomes. RESULTS: Data on 139,304 patients (74% male, 84% White) were retrieved. Patients were stratified by facility type, with 50,349 patients (36%) treated at ACs and 88,955 patients (64%) treated at non-ACs. Patients treated at ACs were more likely to have private insurance (41% vs 34%, p < 0.001) and less likely to have Medicare (46% vs 57%, p < 0.001). Patients treated at ACs were more likely to have larger tumors (36.91 mm vs 33.57 mm, p < 0.001) and more likely to undergo surgery (47% vs 34%, p < 0.001). Interestingly, patients treated at ACs had decreased comorbidities (Charlson Comorbidity Index rating 0: 74% vs 69%) and similar income levels (income ≥ $46,000: 44% vs 43%). With respect to survival outcomes, patients treated at ACs demonstrated a higher median OS at 10 years than patients treated at non-ACs (65.2% vs 54.1%). The association of improved OS in patients treated at ACs continued to be true when adjusting for all other clinical and demographic variables (HR 0.900, 95% CI 0.882-0.918; p < 0.001). CONCLUSIONS: The results of this study indicate that facility type is associated with disparate survival outcomes in the treatment of intracranial meningiomas. Namely, patients treated at non-ACs appear to have a survival disadvantage even when controlling for additional comorbidities.

OBJECTIVE: The American Association of Neurological Surgeons (AANS) and Congress of Neurological Surgeons (CNS) Joint Cerebrovascular (CV) Section serves as a centralized entity for the dissemination of information related to CV neurosurgery. The quality of scientific conferences, such as the CV Section's Society of NeuroInterventional Surgery Annual Meeting, can be gauged by the number of poster and oral presentations that are published in peer-reviewed journals. However, publication rates from the CV Section's meetings are unknown. The objective of this study was to assess the rate at which abstracts presented at the AANS/CNS CV Section Annual Meeting from 2014 to 2018 were subsequently published in peer-reviewed journals. METHODS: The abstract titles for all accepted poster and oral podium presentation abstracts from the 2014-2018 Annual Joint AANS/CNS CV Section Meetings were searched using PubMed. A match was defined as sufficient similarity between the abstract and its corresponding journal publication with regard to title, authors, methods, and results. Five-year impact factors (IFs) from Journal Citation Reports (JCR), the country of the corresponding author, and the number of citations in the Scopus database were obtained using the articles' digital object identifier when available, or the exact article title, journal, and year of publication. RESULTS: Of the 607 total poster and oral presentations from the 2014-2018 Annual Meetings of the AANS/CNS Joint CV Section, 46.29% (n = 281) have been published. Published articles received 3233 total citations for an average number of citations per article (± SD) of 10.89 ± 16.37. The average 5-year JCR IF of published studies was 4.64 ± 3.13. Additionally, 98.22% of published abstracts were in publication within 4 years from the time the abstract was presented. The most common peer-reviewed neurosurgical journals featuring these publications were the Journal of Neurosurgery, World Neurosurgery, the Journal of NeuroInterventional Surgery, Neurosurgery, and the Journal of Clinical Neuroscience. CONCLUSIONS: Nearly half of all poster and oral presentations at the annual meetings of the AANS/CNS Joint CV Section from 2014 to 2018 have been published in PubMed-indexed, peer-reviewed journals. The average number of citations per publication (10.89 ± 16.37) reflects the high quality of abstracts accepted for presentation. It is important to continuously assess the quality of research presented at national conferences to ensure that standards are being maintained for the advancement of clinical practice in a given area of medicine. Conference abstract publication rates in peer-reviewed journals represent a way in which research quality can be gauged, and the authors encourage others to conduct similar investigations in their subspecialty area of interest and/or practice.
RESUMEN
BACKGROUND: Trigeminal neuralgia (TN) is a debilitating orofacial pain disorder. Recent data from a national database suggest that microvascular decompression (MVD) in frail patients is associated with more postoperative complications. However, the long-term pain outcomes for frail TN patients are not known. We aimed to elucidate the relationship between frailty and long-term pain outcomes after MVD for TN. METHODS: From 2007 to 2020, 368 TN patients aged ≥60 years underwent MVD at our institution. Patient demographics, clinical characteristics, postoperative complications, and long-term pain outcomes were recorded. Frailty was assessed using the modified 5-item frailty index (mFI-5) score, and the patients were dichotomized into nonfrail (mFI-5 <2) and frail (mFI-5 >1). Differences were assessed via the t test, χ2 test, multivariate ordinal regression, and Cox proportional hazards analysis. RESULTS: Of the 368 patients analyzed, 9.8% were frail. The frail patients were significantly older (P = 0.02) with a higher body mass index (P = 0.01) and a greater incidence of comorbidities (P < 0.001). Frail patients presented with significantly higher pain levels at the final follow-up (P = 0.04). On multivariate analysis, frailty was independently associated with more pain at follow-up (P = 0.01), as was younger age, female sex, and black race. The relationship between frailty and postoperative pain recurrence showed a trend toward significance (P = 0.06), and younger age and black race were significantly associated with recurrence. CONCLUSIONS: Frail patients undergoing MVD are at risk of worse long-term pain outcomes.

Meningiomas are neoplasms derived from the arachnoid cap cells of the leptomeninges and are the most common intracranial tumor. In the present historical vignette, the evolution of the management and diagnosis of meningioma is described. We begin with studies of skulls from the prehistoric record, such as the Steinheim skull, which demonstrate morphologic changes (e.g., hyperostosis) now known to occur with meningioma growth. We then continue with the earliest formal descriptions of meningiomas, including that by Platter, who published the first report of meningioma, along with early histopathologic descriptions by Cushing, who divined the cytological origins of the tumor and was the first to use the term meningioma. We conclude with a description of current management of meningiomas and potential avenues for further discovery. This article is effectively a lifetime biography of a tumor known and loved by neurosurgeons, the simple and yet complex meningioma.
RESUMEN
INTRODUCTION: Hydrocephalus is a common pediatric neurosurgical pathology, typically treated with a ventricular shunt, yet approximately 30% of patients experience shunt failure within the first year after surgery. As a result, the objective of the present study was to validate a predictive model of pediatric shunt complications with data retrieved from the Healthcare Cost and Utilization Project (HCUP) National Readmissions Database (NRD). METHODS: The HCUP NRD was queried from 2016 to 2017 for pediatric patients undergoing shunt placement using ICD-10 codes. Comorbidities present upon initial admission resulting in shunt placement, Johns Hopkins Adjusted Clinical Groups (JHACG) frailty-defining criteria, and Major Diagnostic Category (MDC) at admission classifications were obtained. The database was divided into training (n = 19,948), validation (n = 6,650), and testing (n = 6,650) datasets. Multivariable analysis was performed to identify significant predictors of shunt complications which were used to develop logistic regression models. Post hoc receiver operating characteristic (ROC) curves were created. RESULTS: A total of 33,248 pediatric patients aged 6.9 ± 5.7 years were included. Number of diagnoses during primary admission (OR: 1.05, 95% CI: 1.04-1.07) and initial neurological admission diagnoses (OR: 3.83, 95% CI: 3.33-4.42) positively correlated with shunt complications. Female sex (OR: 0.87, 95% CI: 0.76-0.99) and elective admissions (OR: 0.62, 95% CI: 0.53-0.72) negatively correlated with shunt complications. ROC curve for the regression model utilizing all significant predictors of readmission demonstrated area under the curve of 0.733, suggesting these factors are possible predictors of shunt complications in pediatric hydrocephalus. CONCLUSION: Efficacious and safe treatment of pediatric hydrocephalus is of paramount importance. Our machine learning algorithm delineated possible variables predictive of shunt complications with good predictive value.

BACKGROUND: Since its proposal, the Global Alignment and Proportion (GAP) score has been the topic of several external validation studies, which have yielded conflicting results. Given the lack of consensus regarding this prognostic tool, the authors aim to assess the accuracy of GAP scores for predicting mechanical complications following adult spinal deformity correction surgery. METHODS: A systematic search was performed using PubMed, Embase, and Cochrane Library for the purpose of identifying all studies evaluating the GAP score as a predictive tool for mechanical complications. GAP scores were pooled using a random-effects model to compare patients reporting mechanical complications after surgery versus those reporting no complications. Where receiver operator curves were provided, the area under the curve (AUC) was pooled. RESULTS: A total of 15 studies featuring 2092 patients were selected for inclusion. Qualitative analysis using Newcastle-Ottawa criteria revealed moderate quality among all included studies (5.99/9). With respect to sex, the cohort was predominantly female (82%). The pooled mean age among all patients in the cohort was 58.55 years, with a mean follow-up of 33.86 months after surgery. Upon pooled analysis, we found that mechanical complications were associated with higher mean GAP scores, albeit minimal (mean difference = 0.571 [ 95% confidence interval: 0.163-0.979]; P = 0.006, n = 864). Additionally, age (P = 0.136, n = 202), fusion levels (P = 0.207, n = 358), and body mass index (P = 0.616, n = 350) were unassociated with mechanical complications. Pooled AUC revealed poor discrimination overall (AUC = 0.69; n = 1206). CONCLUSIONS: GAP scores may have a minimal-to-moderate predictive capability for mechanical complications associated with adult spinal deformity correction.
RESUMEN
OBJECTIVE: To gauge resident knowledge in the socioeconomic aspects of neurosurgery and assess the efficacy of an asynchronous, longitudinal, web-based, socioeconomics educational program tailored for neurosurgery residents. METHODS: Trainees completed a 20-question pre- and post-intervention knowledge examination including four educational categories: billing/coding, procedure-specific concepts, material costs, and operating room protocols. Structured data from 12 index cranial neurosurgical operations were organized into 5 online, case-based modules sent to residents within a single training program via weekly e-mail. Content from each educational category was integrated into the weekly modules for resident review. RESULTS: Twenty-seven neurosurgical residents completed the survey. Overall, there was no statistically significant difference between pre- vs post-intervention resident knowledge of billing/coding (79.2 % vs 88.2 %, p = 0.33), procedure-specific concepts (34.3 % vs 39.2 %, p = 0.11), material costs (31.7 % vs 21.6 %, p = 0.75), or operating room protocols (51.7 % vs 35.3 %, p = 0.61). However, respondents' accuracy increased significantly by 40.8 % on questions containing content presented more than 3 times during the 5-week study period, compared to an increased accuracy of only 2.2 % on questions containing content presented less often during the same time period (p = 0.05). CONCLUSIONS: Baseline resident knowledge in socioeconomic aspects of neurosurgery is relatively lacking outside of billing/coding. Our socioeconomic educational intervention demonstrates some promise in improving socioeconomic knowledge among neurosurgery trainees, particularly when content is presented frequently. This decentralized, web-based approach to resident education may serve as a future model for self-driven learning initiatives among neurosurgical residents with minimal disruption to existing workflows.

Interbody fusion is a workhorse technique in lumbar spine surgery that facilities indirect decompression, sagittal plane realignment, and successful bony fusion. The 2 most commonly employed cage materials are titanium (Ti) alloy and polyetheretherketone (PEEK). While Ti alloy implants have superior osteoinductive properties they more poorly match the biomechanical properties of cancellous bones. Newly developed 3-dimensional (3D)-printed porous titanium (3D-pTi) address this disadvantage and are proposed as a new standard for lumbar interbody fusion (LIF) devices. In the present study, the literature directly comparing 3D-pTi and PEEK interbody devices is systematically reviewed with a focus on fusion outcomes and subsidence rates reported in the in vitro, animal, and human literature. A systematic review directly comparing outcomes of PEEK and 3D-pTi interbody spinal cages was performed. PubMed, Embase, and Cochrane Library databases were searched according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) guidelines. Mean Newcastle-Ottawa Scale score for cohort studies was 6.4. A total of 7 eligible studies were included, comprising a combination of clinical series, ovine animal data, and in vitro biomechanical studies. There was a total population of 299 human and 59 ovine subjects, with 134 human (44.8%) and 38 (64.4%) ovine models implanted with 3D-pTi cages. Of the 7 studies, 6 reported overall outcomes in favor of 3D-pTi compared to PEEK, including subsidence and osseointegration, while 1 study reported neutral outcomes for device related revision and reoperation rate. Though limited data are available, the current literature supports 3D-pTi interbodies as offering superior fusion outcomes relative to PEEK interbodies for LIF without increasing subsidence or reoperation risk. Histologic evidence suggests 3D-Ti to have superior osteoinductive properties that may underlie these superior outcomes, but additional clinical investigation is merited.
RESUMEN
OBJECTIVE: Chordomas are most frequently found in the sacrum, vertebral column, and skull base. Achieving gross-total resection (GTR) has been shown to optimize overall survival (OS); however, the efficacy of radiotherapy (RT) for patients with GTR is currently not well understood. Given that RT may negatively impact patient quality of life, the aim of this study was to evaluate the utility of RT for improving OS in patients who have undergone GTR of spinal chordoma through analysis of the national Surveillance, Epidemiology, and End Results (SEER) database. METHODS: The SEER database (1975-2018) was queried for all adult patients (≥ 21 years) who underwent GTR for spinal chordoma. Bivariate analysis was conducted using chi-square testing for categorical variables, and the log-rank test was performed to find the associations of clinical variables with OS. Cox proportional hazards models were generated for multivariate analyses of the associations among clinical variables and OS. RESULTS: A total of 263 spinal chordomas that underwent GTR were identified. The mean age of all included patients was 58.72 years, and 63.9% of patients were male. In addition, 0.4% had dedifferentiated histology. The mean follow-up was 75.54 months. Of all patients, 152 (57.8%) received no RT and 111 (42.2%) received RT. Patients with sacral tumor location (80.9% vs 51.4%, p < 0.001) were more likely not to undergo RT when compared to patients with vertebral column location. In multivariate analysis, only age ≥ 65 years was associated with poorer OS (HR 3.16, CI 1.54-5.61, p < 0.001). RT did not have a statistically significant association with OS. CONCLUSIONS: RT after GTR of chordoma did not improve OS among SEER chordoma patients to a value that achieved statistical significance. Additional multicenter prospective studies are needed to determine the true efficacy of RT after GTR of spinal chordoma.
