Background and objectives: Compared with the modified Frailty Index-11 (mFI-11) frailty tool, reflective of patient comorbidities, the Fried phenotype weighs functional patient variables. This study examined using the Fried phenotype in predicting postoperative outcomes in craniotomy for patients with tumor.

Methods: This retrospective cohort analysis included patients with Current Procedural Terminology codes for supratentorial/infratentorial tumor resections and preoperative frailty scores. Chart review collected the remaining variables for the primary outcome, length of stay (LOS), and secondary outcomes, discharge disposition and postoperative complications. Basic descriptive statistics summarized patient demographics, clinical parameters, and postoperative outcomes. χ2 tests, t-tests, and ANOVA examined associations and mean differences. Logistic and Poisson regressions explored predictor-outcome relationships.

Results: Over 7 years, these 153 patients underwent Fried assessments. The Fried score was biased toward females being more frail (nonfrail 38.0% female, prefrail 50.0% female and frail 65.6% female, P = .027) but not by age, body mass index, or tumor type. The mFI-11 was biased by age (nonfrail 67.8 years vs frail 72.3 years, P < .001) and body mass index (nonfrail 27.5 vs frail 30.8, P < .001) but not sex or tumor type. The Fried score was significantly correlated with increased LOS's (odds ratio [OR] = 5.92, 95% CI = 1.66-21.13, P < .001) but the mFI-11 was not (OR = 0.82, 95% CI = 0.35-1.93, P = .64). The Fried phenotype was significantly correlated with discharge disposition location (P = .016), whereas the mFI-11 was not (P = .749). The Fried score was significantly correlated with postoperative complications (OR = 1.36, 95% CI = 1.08-1.71, P = .01), whereas the mFI-11 was not (OR = 1.10, 95% CI = 0.86-1.41, P = .44).

Conclusion: The Fried phenotype more accurately correlates with postoperative outcomes including LOS, discharge disposition location, and complications than does the mFI-11 score. These findings can be used to guide preoperative planning, inform consent, and potentially identify patients who may benefit from functional optimization in the preoperative period to improve postoperative outcomes.

背景和目的:与反映患者合并症的改良虚弱指数-11(mFI-11)虚弱工具相比,弗里德表型更重视患者的功能性变量。本研究探讨了使用弗里德表型预测肿瘤患者开颅手术的术后结果:这项回顾性队列分析纳入了当前程序术语代码为颅内/颅外肿瘤切除术和术前虚弱评分的患者。病历审查收集了主要结果、住院时间(LOS)和次要结果、出院处置和术后并发症的其余变量。基本描述性统计总结了患者的人口统计学特征、临床参数和术后结果。χ2检验、t检验和方差分析检验了相关性和平均差异。逻辑回归和泊松回归探讨了预测因子与结果之间的关系:7年间,153名患者接受了Fried评估。Fried评分偏向于女性更虚弱(非虚弱38.0%为女性,虚弱前50.0%为女性,虚弱65.6%为女性,P = .027),但与年龄、体重指数或肿瘤类型无关。mFI-11 与年龄(非体弱者 67.8 岁 vs 体弱者 72.3 岁,P < .001)和体重指数(非体弱者 27.5 vs 体弱者 30.8,P < .001)有关,但与性别或肿瘤类型无关。Fried 评分与 LOS 的增加有明显相关性(几率比 [OR] = 5.92,95% CI = 1.66-21.13,P < .001),但 mFI-11 则没有相关性(OR = 0.82,95% CI = 0.35-1.93,P = .64)。弗里德表型与出院处置地点有明显相关性(P = .016),而 mFI-11 则没有相关性(P = .749)。Fried评分与术后并发症有明显相关性(OR = 1.36,95% CI = 1.08-1.71,P = .01),而mFI-11则没有相关性(OR = 1.10,95% CI = 0.86-1.41,P = .44):结论:与 mFI-11 评分相比,Fried 表型与术后结果(包括 LOS、出院处置地点和并发症)的相关性更准确。这些研究结果可用于指导术前规划、告知同意意见,并有可能确定哪些患者可能受益于术前的功能优化以改善术后效果。

Background and objectives: Pyogenic spinal infections pose therapeutic challenges, with the optimal treatment approach remaining contentious. This study aimed to compare outcomes of conservative vs early surgical treatment (SuT) modalities in primary pyogenic spondylodiskitis through an international cohort analysis.

Methods: A retrospective outcome analysis was conducted of 392 patients from the United Kingdom and Germany, treated between 2017 and 2022 with primary pyogenic spondylodiskitis. Patients were stratified by treatment modality. Propensity score matching, facilitated by a directed acyclic graph and principal component analysis, was used to balance risk factors between the compared patient cohorts. Primary outcome was mortality rate, while secondary outcomes included hospitalization duration, infection relapse, and neurological status at discharge.

Results: The study included 95 patients undergoing conservative treatment, primarily treated in the United Kingdom, and 297 receiving SuT, predominantly in Germany. The mortality rate was notably higher in the conservative group (P < .001), while the surgical cohort experienced a shorter hospitalization duration (P < .01). After propensity score matching, 2 comparable cohorts of 95 patients each emerged. Subsequent analysis revealed a markedly increased mortality in the conservative group (24.2% for conservative treatment vs 4.2% for SuT, P < .001). Neither relapse nor neurological status at discharge showed significant differences between the groups.

Conclusion: The study indicates that early surgical intervention may be more effective than conservative management in reducing mortality and hospital stay for patients with primary pyogenic spondylodiskitis. These findings highlight the need for prospective trials and more definitive treatment guidelines.

背景和目的:化脓性脊柱感染给治疗带来了挑战,最佳治疗方法仍存在争议。本研究旨在通过国际队列分析,比较原发性化脓性脊柱炎保守治疗与早期手术治疗(SuT)的疗效:对2017年至2022年间接受治疗的392名英国和德国原发性化脓性脊柱炎患者进行了回顾性结果分析。根据治疗方式对患者进行了分层。在有向无环图和主成分分析的帮助下,采用倾向评分匹配法来平衡比较患者队列之间的风险因素。主要结果是死亡率,次要结果包括住院时间、感染复发和出院时的神经状况:研究包括 95 名主要在英国接受保守治疗的患者和 297 名主要在德国接受 SuT 治疗的患者。保守治疗组的死亡率明显更高(P < .001),而手术治疗组的住院时间更短(P < .01)。经过倾向评分匹配后,出现了两个具有可比性的队列,各有 95 名患者。随后的分析表明,保守治疗组的死亡率明显升高(保守治疗组为 24.2%,SuT 组为 4.2%,P < .001)。两组患者的复发率和出院时的神经状况均无明显差异:研究表明,在降低原发性化脓性脊柱炎患者的死亡率和住院时间方面,早期手术干预可能比保守治疗更有效。这些发现凸显了进行前瞻性试验和制定更明确的治疗指南的必要性。

Background and objectives: Prediction of patient outcomes after severe traumatic brain injury (sTBI) is limited with current clinical tools. This study aimed to improve such prognostication by combining clinical data and serum inflammatory and neuronal proteins in patients with sTBI to develop predictive models for post-traumatic vasospasm (PTV) and mortality.

Methods: Fifty-three adult civilian patients were prospectively enrolled in the sTBI arm of the Surgical Critical Care Initiative (SC2i). Clinical, serum inflammatory, and neuronal protein data were combined using the parsimonious machine learning methods of least absolute shrinkage and selection operator (LASSO) and classification and regression trees (CART) to construct parsimonious models for predicting development of PTV and mortality.

Results: Thirty-six (67.9%) patients developed vasospasm and 10 (18.9%) died. The mean age was 39.2 years; 22.6% were women. CART identified lower IL9, lower presentation pulse rate, and higher eotaxin as predictors of vasospasm development (full data area under curve (AUC) = 0.89, mean cross-validated AUC = 0.47). LASSO identified higher Rotterdam computed tomography score and lower age as risk factors for vasospasm development (full data AUC 0.94, sensitivity 0.86, and specificity 0.94; cross-validation AUC 0.87, sensitivity 0.79, and specificity 0.93). CART identified high levels of eotaxin as most predictive of mortality (AUC 0.74, cross-validation AUC 0.57). LASSO identified higher serum IL6, lower IL12, and higher glucose as predictive of mortality (full data AUC 0.9, sensitivity 1.0, and specificity 0.72; cross-validation AUC 0.8, sensitivity 0.85, and specificity 0.79).

Conclusion: Inflammatory cytokine levels after sTBI may have predictive value that exceeds conventional clinical variables for certain outcomes. IL-9, pulse rate, and eotaxin as well as Rotterdam score and age predict development of PTV. Eotaxin, IL-6, IL-12, and glucose were predictive of mortality. These results warrant validation in a prospective cohort.

背景和目标:目前的临床工具对严重创伤性脑损伤(sTBI)后患者预后的预测有限。本研究旨在通过结合 sTBI 患者的临床数据、血清炎症蛋白和神经元蛋白来开发创伤后血管痉挛(PTV)和死亡率的预测模型,从而改善这种预后:53名成年平民患者前瞻性地加入了外科重症监护计划(SC2i)的创伤性脑损伤组。使用最小绝对收缩和选择算子(LASSO)以及分类和回归树(CART)等简易机器学习方法将临床、血清炎症和神经元蛋白数据结合起来,构建预测PTV发展和死亡率的简易模型:36例(67.9%)患者出现血管痉挛,10例(18.9%)患者死亡。平均年龄为 39.2 岁,22.6% 为女性。CART 确定了较低的 IL9、较低的脉搏率和较高的 eotaxin 是血管痉挛发生的预测因子(全数据曲线下面积 (AUC) = 0.89,平均交叉验证 AUC = 0.47)。LASSO 将较高的鹿特丹计算机断层扫描评分和较低的年龄确定为血管痉挛发生的风险因素(全数据 AUC 0.94,灵敏度 0.86,特异性 0.94;交叉验证 AUC 0.87,灵敏度 0.79,特异性 0.93)。CART 确定高水平的 eotaxin 最能预测死亡率(AUC 0.74,交叉验证 AUC 0.57)。LASSO 发现血清 IL6 较高、IL12 较低和葡萄糖较高可预测死亡率(全数据 AUC 0.9,灵敏度 1.0,特异性 0.72;交叉验证 AUC 0.8,灵敏度 0.85,特异性 0.79):结论:创伤性脑损伤后炎症细胞因子水平对某些结果的预测价值可能超过传统的临床变量。IL-9、脉搏率、Eotaxin以及鹿特丹评分和年龄可预测PTV的发生。Eotaxin、IL-6、IL-12 和葡萄糖可预测死亡率。这些结果需要在前瞻性队列中进行验证。

Background and objectives: The role of radiosurgery in the treatment of benign intracranial tumors is well established. However, there are limited long-term follow-up studies on outcomes after stereotactic radiosurgery (SRS) for benign intradural spinal tumors. In this article, we report a large single-institution experience in using SRS to treat patients with benign intradural tumors of the spine.

Methods: Overall, 184 patients (55% female) and 207 benign intradural tumors were treated. The median patient age was 52 years (range: 19-93). Tumor histology included schwannoma (38%), meningioma (15%), neurofibroma (21%), hemangioma (9%), hemangioblastoma (8%), hemangiopericytoma (5%), and paraganglioma (4%). Thirty-four (16%) lesions underwent resection before radiosurgery. Twenty-three (11%) lesions were NF1-mutated. The median single-fraction margin dose was 14 Gy (range: 11-20), and the median multifraction margin dose was 21 Gy (range: 15-30).

Results: The median follow-up was 63 months (range: 1-258). At last follow-up, tumors volumetrically regressed (15%), remained stable (77%), or locally progressed (8%, median: 20 months [range: 3-161]) after SRS. The 1-, 5-, and 10-year local control rates were 97%, 92%, and 90%, respectively. On multivariable analysis, the absence of the NF1 mutation (P = .004, hazard ratio: 0.23, 95% CI: 0.08-0.63) and single-fraction SRS (P = .007, hazard ratio: 0.24, 95% CI: 0.08-0.68) correlated with improved local control. The median overall survival was 251 months (range: 1-258), and 1-, 5-, and 10-year overall survival rates were 95%, 85%, and 70%, respectively. For patients with pre-existing symptoms, tumor-associated pain and neurological deficits were noted to improve or remain stable in 85% and 87% of cases, respectively. Adverse radiation effects included delayed myelopathy (1%), acute pain flare (9%), dermatitis (0.5%), dysphagia (0.5%), and dysphonia (0.5%).

Conclusion: With long-term follow-up, spine radiosurgery is a safe and effective treatment for benign intradural tumors. In carefully selected patients, even with an NF1 mutation, SRS is associated with a high likelihood of local tumor control.

背景和目的:放射手术在治疗颅内良性肿瘤中的作用已得到公认。然而,对脊柱硬膜内良性肿瘤进行立体定向放射外科手术(SRS)治疗后的长期随访研究却很有限。在这篇文章中,我们报告了一个大型单机构使用 SRS 治疗脊柱硬膜内良性肿瘤患者的经验:方法:共治疗了 184 名患者(55% 为女性)和 207 个良性硬膜内肿瘤。患者年龄中位数为 52 岁(19-93 岁)。肿瘤组织学包括分裂瘤(38%)、脑膜瘤(15%)、神经纤维瘤(21%)、血管瘤(9%)、血管母细胞瘤(8%)、血管外细胞瘤(5%)和副神经节瘤(4%)。34个病灶(16%)在放射外科手术前进行了切除。23个病灶(11%)为NF1突变。单分次边缘剂量中位数为14 Gy(范围:11-20),多分次边缘剂量中位数为21 Gy(范围:15-30):中位随访时间为 63 个月(范围:1-258)。在最后一次随访中,SRS术后肿瘤体积消退(15%)、保持稳定(77%)或局部进展(8%,中位:20个月[范围:3-161])。1年、5年和10年的局部控制率分别为97%、92%和90%。在多变量分析中,无 NF1 突变(P = .004,危险比:0.23,95% CI:0.08-0.63)和单剂量 SRS(P = .007,危险比:0.24,95% CI:0.08-0.68)与局部控制率的改善相关。中位总生存期为251个月(范围:1-258),1年、5年和10年总生存率分别为95%、85%和70%。对于已有症状的患者,85%和87%的病例中肿瘤相关疼痛和神经功能缺损得到改善或保持稳定。放射不良反应包括延迟性脊髓病(1%)、急性疼痛发作(9%)、皮炎(0.5%)、吞咽困难(0.5%)和发音障碍(0.5%):结论:经过长期随访,脊柱放射手术是一种安全有效的硬膜内良性肿瘤治疗方法。结论:经过长期随访,脊柱放射手术是治疗硬膜内良性肿瘤的安全有效方法。对于经过严格筛选的患者,即使存在 NF1 基因突变,脊柱放射手术也能很好地控制局部肿瘤。

Background and objectives: Surveillance studies offer sparse knowledge of predictors of future growth in sporadic vestibular schwannomas (VS).Our aim was identification of these risk factors. We propose a scoring system to estimate the risk of growth in sporadic vestibular schwannoma.

Methods: This retrospective study is based on the demographic and radiological data of 615 adult patients under the surveillance for single VS in our center. Univariate analysis, multivariate regression, and Kaplan-Meier analysis were used when appropriate. The regression coefficient-based "VS score" was calculated based on Cox proportional-hazards regression.

Results: During surveillance, 285 tumors (46%) remained stable, 314 tumors (51%) grew, and 16 tumors (3%) shrank. The significant risks factors for future growth identified both in univariate and multivariate analyses were younger age at onset, cystic morphology, larger tumor volume, and cisternal location (as per Hannover grade). The proportion of growing tumors was 40%, 75%, and 96% among the homogeneous VS, primary cystic, and VS transformed to cystic, respectively. Moreover, tumor growth during the 1st year was significant predictor of continuous growth. Our "VS score" includes variables such as age, sex, morphology, and Hannover grade. The score extends between -3 and 6 points. Kaplan-Meier, confusion matrix, and receiver operating characteristic analysis proved high accuracy of our scoring model.

Conclusion: Our retrospective study revealed that younger age, cystic morphology, cisternal extent, larger volume, and growth during 1st year were strong predictors of future growth. Moreover, we propose a scoring system that accurately estimates the risks of future tumor growth.

背景和目的:监测研究对散发性前庭神经分裂瘤(VS)未来生长的预测因素知之甚少。我们提出了一个评分系统来估算散发性前庭神经分裂瘤的生长风险:这项回顾性研究基于本中心监测的 615 名单发前庭神经分裂瘤成年患者的人口统计学和放射学数据。在适当的时候采用单变量分析、多变量回归和卡普兰-梅耶分析。基于回归系数的 "VS 评分 "是根据 Cox 比例危险度回归计算得出的:在监测期间,285 个肿瘤(46%)保持稳定,314 个肿瘤(51%)增大,16 个肿瘤(3%)缩小。在单变量和多变量分析中发现,未来肿瘤生长的重要危险因素包括发病年龄较小、囊性形态、肿瘤体积较大和阴囊位置(根据汉诺威分级)。在同种VS、原发囊性VS和转化为囊性VS中,肿瘤生长的比例分别为40%、75%和96%。此外,肿瘤在第一年的生长情况也能显著预测肿瘤的持续生长。我们的 "VS 评分 "包括年龄、性别、形态和汉诺威分级等变量。得分范围在-3 到 6 分之间。Kaplan-Meier、混淆矩阵和接收者操作特征分析表明,我们的评分模型具有很高的准确性:我们的回顾性研究表明,较小的年龄、囊肿形态、囊腔范围、较大的体积以及第一年的生长情况是未来生长的有力预测因素。此外,我们还提出了一种能准确估计肿瘤未来生长风险的评分系统。

Background and objectives: Access to neurosurgical care is limited in low-income and middle-income countries (LMICs) and in marginalized communities in high-income countries (HICs). International partnerships represent one possible means of addressing this issue. Insights from surgeons in HICs have been explored, but data from LMICs' counterparts are scarce. We aimed to study the perspectives of neurosurgeons and trainees from LMICs regarding global neurosurgery (GN) collaborations and interests, motivators, and challenges in participating.

Methods: An online survey was conducted targeting neurosurgeons and trainees from LMICs. The survey explored demographics, previous experiences, ongoing activities, interests, and barriers related to GN activities. Data were collected between July 2022 and December 2022 and analyzed.

Results: Responses involved 436 individuals. The most represented region (25%) was sub-Saharan Africa, and most respondents were male (87.8%) aged 35-49 years. Interest in GN was high, with 91% after its developments. Most respondents (96.1%) expressed interest in training, professional, or research experience in HICs, but only 18.1% could cover the expenses. A majority (73.2%) strongly agreed to return to their home country for work after HIC training. Ongoing HIC-LMIC partnerships were reported by 27.8% of respondents. Clinical exposure emerged as the most relevant motivating factor (87%), while financial concerns, lack of opportunities, and lack of program support were identified as important barriers. Funding and dedicated time were highlighted as the most crucial facilitators.

Conclusion: Understanding the perspectives of neurosurgeons and trainees from LMICs is essential to expanding HICs-LMICs collaborations and improving access to neurosurgical care worldwide. Financial support and targeted interventions are needed to address barriers and promote equitable partnerships in GN.

背景和目标:在低收入和中等收入国家(LMICs)以及高收入国家(HICs)的边缘化社区,获得神经外科治疗的机会有限。国际合作是解决这一问题的可行方法之一。高收入国家(HIC)外科医生的见解已经得到探讨,但低收入国家(LMIC)外科医生的数据却很少。我们的目的是研究低收入国家的神经外科医生和受训人员对全球神经外科(GN)合作的看法,以及参与合作的兴趣、动力和挑战:针对来自低收入国家的神经外科医生和受训人员进行了在线调查。调查内容包括人口统计学、以往经验、正在进行的活动、兴趣以及与全球网络活动相关的障碍。数据收集于 2022 年 7 月至 2022 年 12 月,并进行了分析:共收到 436 份回复。撒哈拉以南非洲地区的受访者最多(占 25%),大多数受访者为男性(87.8%),年龄在 35-49 岁之间。91%的受访者关注全球营养网络的发展。大多数受访者(96.1%)表示有兴趣到高收入国家进行培训、专业或研究体验,但只有 18.1%的受访者能够支付相关费用。大多数受访者(73.2%)强烈同意在接受了高收入国家的培训后回国工作。27.8%的受访者表示他们正在与低收入国家合作。临床经验是最重要的激励因素(87%),而财务问题、缺乏机会和缺乏计划支持则被认为是重要的障碍。结论:了解神经外科医生的观点,有助于他们更好地了解自己的工作:了解来自低收入与中等收入国家的神经外科医生和受训人员的观点,对于扩大低收入与中等收入国家之间的合作以及改善全球神经外科医疗服务的可及性至关重要。需要提供财政支持和有针对性的干预措施,以消除障碍并促进全球神经网络的公平合作。

Background and objectives: We aimed to develop and validate a prediction score for futile recanalization (FR) for large vessel occlusion (LVO) presenting low Alberta Stroke Program Early Computed Tomography Score (ASPECTS) for patients who underwent endovascular thrombectomy (EVT).

Methods: Patients with anterior circulation LVO with low ASPECTS (<6) who underwent successful EVT (modified treatment in cerebral ischemia score ≥2b) from Stroke Thrombectomy and Aneurysm Registry were retrospectively analyzed. FR was defined as 90-day modified Rankin Scale (mRS) scores ≥4 despite successful EVT. Multivariable logistic regression was used to identify independent predictors of FR, and they were used to create a clinical score. The performance of the score was assessed by receiver operating characteristic curve analyses.

Results: Of 219 patients, 170 and 49 patients were randomly assigned to the training and validation cohort, respectively. Independent predictors of FR identified in the training cohort were used to construct the SNAP score: site of occlusion (middle cerebral artery = 0, internal carotid artery = 1), National Institutes of Health Stroke Scale score at admission (≤10 = 0, 10 to 19 = 1, ≥20 = 2), age (<75 = 0, ≥75 = 2), and prestroke mRS score (0-3). Receiver operating characteristic curve analyses of the SNAP score in the training and validation cohorts showed areas under the curve of 0.79 (95% CI 0.72-0.86) and 0.79 (95% CI 0.65-0.92) for predicting FR, respectively. A SNAP score ≥5 had a positive predictive value of 92.1% [95% CI 78.8%-97.3%] for FR.

Conclusion: The SNAP score may be useful in predicting FR after EVT in low-ASPECTS patients with LVO. It can provide patients, family members, and physicians with reliable outcome expectations among patients with acute ischemic stroke with large infarcts.

Background and objectives: Symptomatic chronic subdural hematoma (CSDH) is caused by repetitive hemorrhage and inflammation, which is commonly treated with burr-hole surgery and has a relatively high postoperative recurrence rate. A decrease in the platelet count is indicative of a hemorrhagic tendency, while an increase in the eosinophil count is associated with inflammation. Assessing the balance between platelet-associated hemostasis and eosinophil-associated inflammation using the indeterminate biomarker, the eosinophil-platelet ratio (EPR), may be essential. Therefore, in this study, the accuracy of the EPR in predicting postoperative CSDH recurrence was evaluated and their correlation was determined.

Methods: Data on symptomatic CSDHs of the cerebral hemisphere of patients who underwent burr-hole surgery at our institution between January 2013 and December 2022 were retrospectively reviewed. The EPR was calculated from preoperative peripheral blood examination data, and its correlation with postoperative CSDH recurrence was assessed. The hemispheres with CSDH were categorized into recurrence and nonrecurrence cohorts.

Results: Data from 459 cerebral hemispheres of 405 patients with symptomatic CSDH were analyzed. In the 459 cerebral hemispheres with CSDH, 39 (8.5%) had postoperative recurrence. CSDH patients with a high EPR (≥1 × 10-3) had a significantly higher recurrent rate than those with a low EPR (<1 × 10-3) (15 of 86 [17.4%] vs 24 of 373 [6.4%], P = .002). In the modified Poisson regression analysis, the crude and adjusted risk ratios of high EPR were 2.79 (95% CI: 1.53, 5.09) and 2.62 (95% CI: 1.40, 4.89), respectively.

Conclusion: This study reveals that a high EPR is a useful predictive biomarker for postoperative CSDH recurrence. Cases of CSDH with a high EPR potentially require careful and close postoperative follow-up.

背景和目的:症状性慢性硬膜下血肿(CSDH)是由反复出血和炎症引起的,通常采用钻孔手术治疗,术后复发率相对较高。血小板计数减少表明有出血倾向,而嗜酸性粒细胞计数增加则与炎症有关。使用嗜酸性粒细胞-血小板比值(EPR)这一不确定的生物标志物来评估血小板相关止血和嗜酸性粒细胞相关炎症之间的平衡可能是至关重要的。因此,本研究评估了 EPR 预测 CSDH 术后复发的准确性,并确定了两者之间的相关性:方法:回顾性审查了2013年1月至2022年12月期间在我院接受钻孔手术的大脑半球无症状CSDH患者的数据。根据术前外周血检查数据计算EPR,并评估其与术后CSDH复发的相关性。将患有CSDH的大脑半球分为复发组和未复发组:结果:分析了 405 名有症状 CSDH 患者的 459 个大脑半球的数据。在 459 例 CSDH 患者的大脑半球中,39 例(8.5%)术后复发。高 EPR(≥1 × 10-3)的 CSDH 患者的复发率明显高于低 EPR 患者(结论:本研究表明,高 EPR 是预测 CSDH 术后复发的有效生物标志物。高 EPR 的 CSDH 病例可能需要进行仔细和密切的术后随访。

Background and objectives: This study explores perceived cognitive function in preoperative cranial neurosurgical patients and its association with neuropsychological testing (NPT).

Methods: A total of 96 patients were referred for NPT by neurosurgical service. Patients completed the Neuro-QoL Item Bank v2.0-Cognitive Function-Short Form (Neuro-QoL) to measure perceived cognitive function, as well as NPT. Linear regression (LR) models were analyzed for demographic variables (ie, age, sex, handedness, educational attainment, employment/academic status, candidacy vs baseline testing, and history of neurological, mental health, and developmental conditions) and NPT outcomes (ie, intellectual estimation, attention/working memory, processing speed, executive functioning, learning/memory, language, visual-spatial, anxiety symptoms, and depression symptoms). Significant predictors from the LR models were then combined into a single model to identify the most robust predictors of perceived cognitive function.

Results: Patients were aged 17 to 79 years (M = 49.64, SD = 18.56) and comprised 45 men and 51 women. The most common referrals for NPT were related to intracranial mass (39%), Chiari malformation type 1 (33%), and deep brain stimulation (20%). Results of the final LR model indicated mental health and developmental history, as well as elevated anxiety symptoms, significantly predicted 50.7% of the variance in perceived cognitive function (F = 30.91, P < .001). Patients referred to determine surgical candidacy reported significantly fewer cognitive complaints (P < .001) vs those referred for baseline testing by approximately 0.5 SDs.

Conclusion: Perceived cognitive function in neurosurgical patients appears to be strongly predicted by demographic factors, with mental health variables being robust predictors. Perceived cognition is not a proxy for measured cognitive function.

背景和目的:本研究探讨了颅脑神经外科患者术前的认知功能及其与神经心理测试(NPT)的关系:方法:共有 96 名患者由神经外科转介接受神经心理测试。患者填写了神经-QoL项目库v2.0-认知功能简表(Neuro-QoL),以测量认知功能感知和NPT。线性回归(LR)模型分析了人口统计学变量(即年龄、性别、手型、教育程度、就业/学业状况、候选资格与基线测试,以及神经、心理健康和发育状况病史)和 NPT 结果(即智力估计、注意力/工作记忆、处理速度、执行功能、学习/记忆、语言、视觉空间、焦虑症状和抑郁症状)。然后将LR模型中的重要预测因子合并到一个单一模型中,以确定认知功能感知的最可靠预测因子:患者年龄在 17 至 79 岁之间(中位数 = 49.64,标准差 = 18.56),其中男性 45 人,女性 51 人。最常见的 NPT 转诊病例与颅内肿块(39%)、Chiari 畸形 1 型(33%)和深部脑刺激(20%)有关。最终 LR 模型的结果表明,心理健康和发育史以及焦虑症状的升高可显著预测认知功能感知方差的 50.7%(F = 30.91,P < .001)。为确定手术候选资格而转诊的患者报告的认知症状明显少于为基线测试而转诊的患者(P < .001),相差约 0.5 SDs:结论:神经外科患者的认知功能似乎受到人口统计学因素的强烈影响,而心理健康变量是强有力的预测因素。感知认知并不能代表测量的认知功能。
