Althoughanti-inflammatory drug therapy has been identified as potentially beneficial for patients suffering from chronic subdural hematoma (cSDH), contemporary literature presents contradictory results. In this meta-analysis, we aimed to investigate the impact of anti-inflammatory drug therapy on mortality and outcome. We searched for eligible randomized, placebo-controlled prospective trials (RTCs) on PubMed, Embase and Medline until July 2022. From 97 initially identified articles, five RTCs met the criteria and were included in our meta-analysis. Our results illustrate significantly lower rates of recurrent cSDH (OR: 0.35; 95% CI: 0.21–0.58, p = 0.0001) in patients undergoing anti-inflammatory therapy. In the subgroup of patients undergoing primary conservative treatment, anti-inflammatory therapy was associated with lower rates of “switch to surgery” cases (OR: 0.30; 95% CI: 0.14–0.63, p = 0.002). Despite these findings, anti-inflammatory drugs seemed to be associated with higher mortality rates in patients undergoing surgery (OR: 1.76; 95% CI: 1.03–3.01, p = 0.04), although in the case of primary conservative treatment, no effect on mortality has been observed (OR: 2.45; 95% CI: 0.35–17.15, p = 0.37). Further multicentric prospective randomized trials are needed to evaluate anti-inflammatory drugs as potentially suitable therapy for asymptomatic patients with cSDH to avoid the necessity of surgical hematoma evacuation on what are predominantly elderly, vulnerable, patients.

ObjectIncreasing age is a known negative prognostic factor for glioblastoma. However, a multifactorial approach is necessary to achieve optimal neuro-oncological treatment. It remains unclear to what extent frailty, comorbidity burden, and obesity might exert influence on survival in geriatric glioblastoma patients. We have therefore reviewed our institutional database to assess the prognostic value of these factors in elderly glioblastoma patients.MethodsBetween 2012 and 2018, patients aged ≥ 65 years with newly diagnosed glioblastoma were included in this retrospective analysis. Patients frailty was analyzed using the modified frailty index (mFI), while patients comorbidity burden was assessed according to the Charlson comorbidity index (CCI). Body mass index (BMI) was used as categorized variable.ResultsA total of 110 geriatric patients with newly diagnosed glioblastoma were identified. Geriatric patients categorized as least-frail achieved a median overall survival (mOS) of 17 months, whereas most frail patients achieved a mOS of 8 months (p = 0.003). Patients with a CCI > 2 had a lower mOS of 6 months compared to patients with a lower comorbidity burden (12 months; p = 0.03). Multivariate analysis identified “subtotal resection” (p = 0.02), “unmethylated MGMT promoter status” (p = 0.03), “BMI < 30” (p = 0.04), and “frail patient (mFI ≥ 0.27)” (p = 0.03) as significant and independent predictors of 1-year mortality in geriatric patients with surgical treatment of glioblastoma (Nagelkerke's R2 0.31).ConclusionsThe present study concludes that both increased frailty and comorbidity burden are significantly associated with poor OS in geriatric patients with glioblastoma. Further, the present series suggests an obesity paradox in geriatric glioblastoma patients.

It is unknown whether decompressive craniectomy improves clinical outcome for people with spontaneous severe deep intracerebral haemorrhage. The SWITCH trial aimed to assess whether decompressive craniectomy plus best medical treatment in these patients improves outcome at 6 months compared to best medical treatment alone. In this multicentre, randomised, open-label, assessor-blinded trial conducted in 42 stroke centres in Austria, Belgium, Finland, France, Germany, the Netherlands, Spain, Sweden, and Switzerland, adults (18–75 years) with a severe intracerebral haemorrhage involving the basal ganglia or thalamus were randomly assigned to receive either decompressive craniectomy plus best medical treatment or best medical treatment alone. The primary outcome was a score of 5–6 on the modified Rankin Scale (mRS) at 180 days, analysed in the intention-to-treat population. This trial is registered with ClincalTrials.gov, NCT02258919, and is completed. SWITCH had to be stopped early due to lack of funding. Between Oct 6, 2014, and April 4, 2023, 201 individuals were randomly assigned and 197 gave delayed informed consent (96 decompressive craniectomy plus best medical treatment, 101 best medical treatment). 63 (32%) were women and 134 (68%) men, the median age was 61 years (IQR 51–68), and the median haematoma volume 57 mL (IQR 44–74). 42 (44%) of 95 participants assigned to decompressive craniectomy plus best medical treatment and 55 (58%) assigned to best medical treatment alone had an mRS of 5–6 at 180 days (adjusted risk ratio [aRR] 0·77, 95% CI 0·59 to 1·01, adjusted risk difference [aRD] −13%, 95% CI −26 to 0, p=0·057). In the per-protocol analysis, 36 (47%) of 77 participants in the decompressive craniectomy plus best medical treatment group and 44 (60%) of 73 in the best medical treatment alone group had an mRS of 5–6 (aRR 0·76, 95% CI 0·58 to 1·00, aRD −15%, 95% CI −28 to 0). Severe adverse events occurred in 42 (41%) of 103 participants receiving decompressive craniectomy plus best medical treatment and 41 (44%) of 94 receiving best medical treatment. SWITCH provides weak evidence that decompressive craniectomy plus best medical treatment might be superior to best medical treatment alone in people with severe deep intracerebral haemorrhage. The results do not apply to intracerebral haemorrhage in other locations, and survival is associated with severe disability in both groups.

To date, gross total resection (GTR) of the contrast-enhancing area of glioblastoma (GB) is the benchmark treatment regarding surgical therapy. However, GB infiltrates beyond those margins, and most tumors recur in close proximity to the initial resection margin. It is unclear whether a supramarginal resection (SMR) enhances progression-free survival (PFS) time without increasing the incidence of postoperative surgical complications. The aim of the present meta-analysis was to investigate SMR with regard to PFS and postoperative surgical complications. We searched for eligible studies comparing SMR techniques with conventional GTR in PubMed, Cochrane Library, Web of Science, and Medline databases. From 3158 initially identified records, 11 articles met the criteria and were included in our meta-analysis. Our results illustrate significantly prolonged PFS time in SMR compared with GTR (HR: 11.16; 95% CI: 3.07–40.52, p = 0.0002). The median PFS of the SMR arm was 8.44 months (95% CI: 5.18–11.70, p < 0.00001) longer than the GTR arm. The rate of postoperative surgical complications (meningitis, intracranial hemorrhage, and CSF leaks) did not differ between the SMR group and the GTR group. SMR resulted in longer median progression-free survival without a negative postoperative surgical risk profile. Multicentric prospective randomized trials with a standardized definition of SMR and analysis of neurologic functioning and health-related quality of life are justified and needed to improve the level of evidence.

Background: Aneurysmal subarachnoid hemorrhage (aSAH) is still a fatal and morbid disease, although bleeding aneurysms can be secured in almost all cases. Occurrence of post-SAH complications including cerebral vasospasm, delayed cerebral ischemia, hydrocephalus, epilepsy, and infections are the main determinants of clinical outcome. Hence, it is important to search for early predictors for specific post-SAH complications to treat these complications properly. Both cellular and molecular (cytokines) inflammation play a key role after aSAH during the phase of occurrence of post-SAH complications. Interleukin-6 (IL-6) is a well-known cytokine that has been extensively analyzed in cerebrospinal fluid (CSF) of patients after aSAH, but detailed studies exploring the role of systemic IL-6 in aSAH associated complications and its impact on early clinical outcome prediction are lacking. The current study aims to analyze the systemic IL-6 levels over two weeks after bleeding and its role in post-SAH complications. Methods: We recruited 80 aSAH patients prospectively who underwent peripheral venous blood withdrawal in serum gel tubes. The blood was centrifuged to harvest the serum, which was immediately frozen at −80 °C until analysis. Serum IL-6 levels were quantified using Immulite immunoassay system. Patient records including age, gender, post-SAH complications, aneurysm treatment, and clinical outcome (modified Rankin scale and Glasgow outcome scale) were retrieved to allow different subgroup analysis. Results: Serum IL-6 levels were significantly raised after aSAH compared to healthy controls over the first two weeks after hemorrhage. Serum IL-6 levels were found to be significantly elevated in aSAH patients presenting with higher Hunt and Hess grades, increasing age, and both intraventricular and intracerebral hemorrhage. Interestingly, serum IL-6 was also significantly raised in aSAH patients who developed seizures, cerebral vasospasm (CVS), and chronic hydrocephalus. IL-6 levels were sensitive to the development of infections and showed an increase in patients who developed pneumoniae. Intriguingly, we found a delayed increase in serum IL-6 in patients developing cerebral infarction. Finally, IL-6 levels were significantly higher in patients presenting with poor clinical outcome in comparison to good clinical outcome at discharge from hospital. Conclusion: Serum IL-6 levels were elevated early after aSAH and remained high over the two weeks after initial bleeding. Serum IL-6 was elevated in different aSAH associated complications, acting as a non-specific marker for post-SAH complications and an important biomarker for clinical outcome at discharge.

ObjectivesRecent retrospective studies found sleep disorders, including obstructive sleep apnea and its symptoms to occur more often in patients following aneurysmal subarachnoid hemorrhage, but studies investigating the incidence of subarachnoid hemorrhage in patients with diagnosed obstructive sleep apnea [OSA] compared to other sleep disorders are missing.MethodsTo test our hypothesis that aneurysmal subarachnoid hemorrhage occurs more often in patients with OSA compared to other sleep disorders, we analyzed clinical data of 5514 patients with OSA, 4150 with other sleep disorders, and 964 patients with aneurysmal subarachnoid hemorrhage diagnosed between 01/01/2007 and 12/31/2016. As a secondary outcome, location and size of the ruptured aneurysm were calculated based on computer tomography. Incidence of SAH, as well as size and location were compared between patients with OSA and patients with other sleep disorders, diagnosed by polysomnography.ResultsAneurysmal subarachnoid hemorrhage occurred in 8.3 per 100,000 patients with sleep disorders per year. Its incidence was significantly higher in patients with obstructive sleep apnea (14.5 per 100,000 patients per year), compared to other sleep disorders (2.4 per 100,000 patients per year; RR = 6.8; p = 0.04). The size of the ruptured aneurysm was larger in patients with OSA (19.0 ± 5.7 mm vs. 8.5 ± 0.5 mm; p = 0.004).InterpretationAneurysmal subarachnoid hemorrhage occurs more often in patients with diagnosed OSA compared to patients with other sleep disorders, possibly due to increased aneurysm enlargement. Obstructive sleep apnea might be a yet unrecognized risk factor for aneurysmal subarachnoid hemorrhage, and sleep apnea screening should be considered in patients with intracranial aneurysm.

Background: Falx and convexity meningiomas can compress surrounding brain structures, frequently resulting in epileptic seizures, which adversely impact the quality of life (QoL) of affected patients. This study aimed to assess postoperative QoL in patients with documented perioperative seizures associated with falx and convexity meningiomas. Methods: The Quality of Life in Epilepsy Inventory-31 (QOLIE-31) was administered to patients who underwent surgery for falx/convexity meningiomas and experienced perioperative seizures. Seizures were defined as those occurring within 30 days pre- or post-surgery. Results: A total of 77 patients responded to the questionnaire, of whom 44 were female and 33 were male. Multivariable analysis showed that falx meningioma was associated with a lower QOLIE-31 score (OR = 4.02, 95% CI: 1.14–14.18, p = 0.03). Furthermore, the presence of peritumoral edema was also associated with lower QOLIE-31 scores (OR = 3.89, 95% CI: 1.04–14.47, p = 0.043). Conclusions: This study demonstrates that perioperative seizures in patients with falx meningiomas significantly impact postoperative quality of life. The presence of peritumoral edema was also associated with poorer QoL outcomes. These findings underscore the importance of targeted management strategies to to improve QoL in meningioma patients experiencing seizures.

IntroductionPatients with non-aneurysmal subarachnoid hemorrhage (SAH) are considered to have an overall benign course of disease compared to patients suffering from aneurysmal SAH. Nevertheless, a small but significant number of such patients might only achieve unfavorable outcome. Therefore, the purpose of the present study was to determine if routine laboratory markers of acute phase response are associated with unfavorable outcome in patients with non-aneurysmal SAH.MethodsFrom 2006 to 2017, 154 patients suffering from non-aneurysmal SAH were admitted to our institution. Patients were stratified according to the distribution of cisternal blood into patients with perimesencephalic SAH (pSAH) versus non-perimesencephalic SAH (npSAH). C-reactive protein (CRP) and white blood cells (WBC) assessments were performed within 24 h of admission as part of routine laboratory workup. Outcome was assessed according to the modified Rankin Scale (mRS) after 6 months and stratified into favorable (mRS 0–2) vs. unfavorable (mRS 3–6).ResultsThe multivariate regression analysis revealed “CRP > 5 mg/l” (p = 0.004, OR 143.7), “WBC count > 12.1 G/l” (p = 0.006, OR 47.8), “presence of IVH” (p = 0.02, OR 13.5), “poor-grade SAH” (p = 0.01, OR 45.2) and “presence of CVS” (p = 0.003, OR 149.9) as independently associated with unfavorable outcome in patients with non-aneurysmal SAH.ConclusionElevated C-reactive protein and WBC count at admission were associated with unfavorable outcome after non-aneurysmal SAH.

IntroductionSupra-total resection in terms of anterior temporal lobectomy (ATL) has gained growing attention with regard to superior long-term disease control for temporal-located glioblastoma. However, aggressive onco-surgical approaches—geared beyond conventional gross total resections (GTR)—may be associated with peri- and postoperative unfavorable events which significantly worsen initial favorable postoperative outcome. In the current study we analyzed our institutional database with regard to patient safety indicators (PSIs), hospital-acquired conditions (HACs) and specific cranial surgery-related complications (CSC) as high standard quality metric profiles in patients that had undergone surgery for temporal glioblastoma.MethodsBetween 2012 and 2018, 61 patients with temporal glioblastoma underwent GTR or temporal lobectomy at the authors’ institution. Both groups of differing resection modalities were analyzed with regard to the incidence of PSIs, HACs and CSCs.ResultsOverall, we found 6 PSI and 2 HAC events. Postoperative hemorrhage (3 out of 61 patients; 5%) and catheter-associated urinary tract infection (2 out 61 patients; 3%) were identified as the most frequent PSIs and HACs. PSIs were present in 1 out of 41 patients (5%) for the temporal GTR and 2 out of 20 patients for the lobectomy group (p = 1.0). Respective rates for PSIs were 5 of 41 (12%) and 1 of 20 (5%) (p = 0.7). Further, CSCs did not yield significant differences between these two resection modalities (p = 1.0).ConclusionWith regard to ATL and GTR as differing onco-surgical approaches these data suggest ATL in terms of an aggressive supra-total resection strategy to preserve perioperative standard safety metric profiles.

Objective Supra-total glioblastoma resection has gained growing attention with regard to superior long-term disease control. However, aggressive onco-surgical approaches—geared beyond conventional gross total resections (GTR)—are limited by the impairment of adjacent eloquent areas at risk that may entail severe postoperative functional morbidity. Against this backdrop we analyzed our institutional database with regard to potential survival benefits of anterior temporal lobectomy as a paradigm for supra-total resection in patients with precisely temporal-located, non-eloquent glioblastoma. Methods Between 2012 and 2017, 38 patients with isolated temporal glioblastoma underwent GTR or temporal lobectomy at the authors’ institution. Both groups of differing resection modalities were compared with regard to postoperative Karnofsky performance score (KPS), progression-free survival (PFS), and overall survival (OS). Results Patients with temporal lobectomy exhibited significantly superior median KPS at the 12 months follow-up compared to the GTR group (median KPS of 80 vs. 60, p = 0.04). Temporal lobectomy was associated with significantly prolonged PFS (p = 0.005) and OS (p = 0.002) coming up to 15 months (95% CI 9.7–22.1) and 23 months (95% CI 14.8–34.5) compared to 7 months (95% CI 3.3–8.3) and 11 months (95% CI 9.2–17.9) for the GTR group. Multivariate analysis revealed temporal lobectomy as the only predictor for both superior PFS (p = 0.037, OR 7.3, 95% CI 1.1–47.4) and OS (p = 0.04, OR 7.8, 95% CI 1.1–55.2). Conclusions These results strongly suggest temporal lobectomy as an aggressive supra-total resection policy to constitute the surgical modality of choice for isolated temporal-located glioblastoma.
