ABSTRACT
BACKGROUND: The subspecialized, clinically-complex nature of neurosurgery should not result in marginalization or under-representation of neurosurgical scientific output. This study aims to provide an overview of the trends of neurosurgical publications in high-impact medical journals during the past three decades. METHODS: An electronic database search was performed to identify all articles affiliated with neurosurgery departments published in 10 highly regarded medical journals. The trend of the proportion of neurosurgical publications to total publications in these journals was examined over time. Subgroup analyses based on location, setting, domain, grant source and topic of the articles were performed. RESULTS: Overall, 2,090 neurosurgical publications were identified in the selected journals, comprising 0.26% of those journals' publications. The proportion of neurosurgical publications to total publications in these journals increased over time, from 0.03% before 1991 to 0.35% after 2020. Most studies were single-center (82.7%), clinical (52.4%), and primary research (89%). The United States (40.1%), China (12.4%) and the UK (7.1%) had the highest number of neurosurgical publications among those analyzed. The share of clinical neurosurgical articles increased over time compared to basic and translational articles (p=0.01). Among neurosurgical subspecialties, neuro-oncology (60.1%), vascular (19.0%) and general (7.0%) had the highest number of publications identified, with substantial increases in vascular publications over time. The mean number of citations per year received by neurosurgical articles has increased over time, from 1.65 (before 1991) to 4.12 (2010-2020). CONCLUSIONS: Neurosurgery's proportion of high-impact journal publications has increased over time.
ABSTRACT
BACKGROUND: Large vessel occlusions (LVO) are a common etiology of morbidity and mortality. The current literature lacks a synthesis of the landscape and trends in research. OBJECTIVE: We aimed to conduct a bibliometric analysis of the 100 most cited original articles on LVOs to assess the current state of research. METHODS: Scopus database was queried from inception to December 2022 to identify the most cited original articles from 4506 retrieved records on LVOs. Publication year, country of origin, total and average annual citation count, and type of study were collected for each article. The journal impact factor (JIF) was obtained from the Journal Citation Reports database. RESULTS: The articles were published between 1994 and 2021, with most (n = 82) published during the 2011-2020 decade. The median total citation count was 108.5, with an interquartile range (IQR) of 81-149.5. The median (IQR) average annual citation count was 15.9 (11.5-22.9). Half of the articles were published in Stroke (n = 35) and Journal of NeuroInterventional Surgery (n = 15), with JIFs ranging from 1.8 to 202.7. The USA was the leading country in contributing to LVO research (n = 45). Most studies focused on the treatment (n = 63) and diagnosis (n = 22) of LVOs. CONCLUSIONS: Most articles were published during the past decade, highlighting the impact of the clinical trials of endovascular treatment on the discipline. With several ongoing clinical trials on the horizon, continued growth of the field is anticipated in the upcoming decades.
ABSTRACT
BACKGROUND: The current research on geriatric patients with spinal chondrosarcoma is limited. This study aimed to investigate the demographics, patterns of care, and survival of geriatric patients with chondrosarcoma of the mobile spine. METHODS: The National Cancer Database was queried from 2008 to 2018 for geriatric patients (60-89 years) with chondrosarcoma of the mobile spine. The primary outcome of this study was overall survival. The secondary outcome was treatment utilization patterns. Survival analyses were conducted using log-rank tests and Cox proportional hazards regressions. Logistic regression models were utilized to assess correlations between baseline variables and treatment utilization. RESULTS: The database retrieved 122 patients. While 43.7% of the patients presented with tumors exceeding 5 cm in size, the incidence of regional lymph node involvement or distant metastases was relatively low, affecting only 5% of the patients. Furthermore, 22.3% of the patients had tumors graded as 3-4. The 5-year overall survival rate was 52.9% (95% confidence interval: 42-66.6). The mortality risk was significantly associated with age, tumor grade and stage, and treatment plan. Most patients (79.5%) underwent surgery, while 35.9% and 4.2% were treated with radiotherapy and chemotherapy, respectively. Age, race, comorbidities, geographical region, tumor stage, and healthcare facility type significantly correlated with treatment utilization. CONCLUSIONS: Surgical resection significantly lowered the mortality risk in geriatric patients with spinal chondrosarcomas. Demographic and geographical factors significantly dictated treatment plans. Further studies are required to assess the role of radiotherapy and chemotherapy in treating these patients in the modern era.
ABSTRACT
BACKGROUND: Cavernous carotid artery aneurysms (CCAAs) represent a common condition seen in clinical practice with significant practice variability. The aim of this systematic review and meta-analysis was to aggregate current evidence on the natural history of CCAAs. METHODS: MEDLINE/PubMed, EMBASE, and Cochrane Library were queried from inception until December 2023. The primary outcome of this study was CCAA-related mortality. The secondary outcomes of this study were aneurysm growth, intracranial ischemic and hemorrhagic events, improved non-cerebrovascular symptoms, and new or worsened non-cerebrovascular symptoms during follow-up. RESULTS: Ten studies met our inclusion criteria, involving 835 patients and 975 CCAAs. CCAA-related mortality had an incidence rate of 0.28 (95% CI 0.12-0.64) per 100 person-years (PYs) of follow-up. The incidence rate of CCAA growth was 2.91 (1.05-8.07) per 100 PYs of follow-up. The incidence rate of CCAA-related intracranial ischemic events was 0.4 (0.16-1.01) per 100 PYs of follow-up. The incidence rate of CCAA-related intracranial hemorrhagic events was 0.54 (0.33-0.87) per 100 PYs of follow-up. The incidence rate of improved non-cerebrovascular symptoms was 2.51 (1.18-5.33) per 100 PYs of follow-up. The incidence rate of new or worsened non-cerebrovascular symptoms was 3.41 (2.03-5.73) per 100 PYs of follow-up. CONCLUSIONS: CCAAs are typically benign lesions with a low risk of rupture and life-threatening complications. CCAAs tend to follow an indolent course regarding non-cerebrovascular outcomes, and new or worsening symptoms are infrequent during the clinical course. However, spontaneous resolution of non-cerebrovascular symptoms and cranial nerve deficits at presentation is uncommon.
ABSTRACT
PURPOSE: This study aims to review the literature to explore some factors affecting sexual and partnership adjustment in individuals with spinal cord injury (SCI). METHODS: This study was based on the methodological framework of scoping reviews, including 3 methodological steps: (1) identifying relevant studies (searching for related studies); (2) selecting related studies; (3) collecting key findings, summarizing, and reporting the results. The electronic databases were searched including Medline (PubMed), Scopus, Web of Science, Embase, and Cochrane Library. Studies were included if they reported data about the related factors of sexual and partnership adjustment in individuals with SCI. No limitations were considered in terms of time or methodology of the search. RESULTS: After the full-text screening, 52 studies were included from the year of 1978 - 2019 with various methodologies. The present review demonstrated that proper sexual health among individuals with SCI is related to several factors including the anatomical factor, level of the injury, completeness of the injury, psycho-social factor, socio-economic status, and type of relationship. CONCLUSION: With consideration of factors affecting sexual and partnership adjustment in individuals with SCI, a better estimation of sexual health can be achieved in clinical to improve the relationship and quality of life.
ABSTRACT
OBJECTIVE: Preventative protocols have efficaciously reduced shunt infection in developed countries. However, the generalizability of these protocols in low-to-middle-income countries (LMICs) remains unclear. Previously, shunt insertion in the authors' center was routinely performed under institutional preventative precautions, which was updated via merging with the Hydrocephalus Clinical Research Network (HCRN) protocol. This study aimed to investigate the ventriculoperitoneal shunt (VPS) infection rates in pediatric patients following the implementation of the adapted protocol. METHODS: The adapted protocol was implemented in all first-time VPS implantations between 2011 and 2021. The primary outcome was a 6-month shunt infection. The Pearson chi-square test was used for categorical variables and the Mann-Whitney U-test for numeric variables to evaluate the correlation with shunt infection. RESULTS: A total of 352 first-time VPS procedures were performed adhering to the adapted protocol. The median age was 5 months, and 189 (53.7%) were male. Overall, 37 patients (10.5%) experienced shunt infection, with 30 (8.5%) occurring within the first 6 months, which was lower than 13.3% infection rate of the previous series of the same center. The infection rate was slightly higher than the 5.7% and 6.0% rates reported by HCRN studies. Patients with shunt infection were significantly younger (7.5 versus 17.5 months, P < 0.001). CONCLUSIONS: This study validates the efficacy of an adapted perioperative protocol in mitigating shunt infection in a high-volume center in a LMIC. Adhering to a step-by-step protocol, modified to suit the healthcare resources and financial constraints of LMICs, could maintain low shunt infection rates that are roughly comparable to those of centers in high-income countries.

BACKGROUND: Intracranial meningioma resection is associated with multiple acute postoperative complications, including cerebrovascular accidents, surgical site infections, and pneumonia. There is a paucity of research on the postoperative timeframe of these complications. Therefore, our objective is to characterize intracranial meningioma resection complications' time courses. METHODS: The National Surgical Quality Improvement Project registry was queried for intracranial meningioma resection cases using CPT codes 61512 and 61519 from years 2016 to 2021. Baseline patient characteristics and 30-day complication frequency were calculated. The mean, median, and interquartile range of postoperative days to occurrence for 17 complications were calculated. Percent incidence predischarge was recorded. Time-to-occurrence curves were created. Rates of 30-day mortality and increased length-of-stay were compared between patients with and without each complication using a χ2 test. A covariance matrix showing associations between 11 complications using the Pearson method was made. Significance was set at P < 0.05. RESULTS: Ten thousand eight hundred ninety cases were analyzed. The most frequent complications' median and interquartile range of postoperative days to occurrence and percentage occurring predischarge were bleeding requiring transfusion (0.0, 0.0-0.0, 99.9%), cerebrovascular accident/stroke with neurological deficit (2.0, 1.0-6.0, 83.8%), unplanned intubation (4.0, 1.0-8.0, 75.1%), on a ventilator for >48 hours (3.0; 2.0-5.5; 88.1%), deep vein thrombosis/thrombophlebitis (12.5, 5.2-19.7, 41.3%), urinary tract infection (13.0, 7.0-20.0, 44.2%), pneumonia (8.0, 4.0-16.0, 60.5%), and pulmonary embolism (14.0, 6.0-20.0, 29.1%). Most complications were associated with increased mortality and length-of-stay. CONCLUSIONS: Postoperative meningioma resection complications have varying morbidity and timeframes. Surgeons should be aware of complication timing to better manage postoperative care.
