95). Patients in the rural group were less likely to undergo craniotomy/craniectomy (adjusted OR, 0.83; 95% CI, 0.77-0.89) and intracranial pressure monitoring (adjusted OR, 0.53; 95% CI, 0.46-0.61) and achieve independent activities of daily living atdischarge (8.2% vs. 10.5%, adjusted OR, 0.85; 95% CI, 0.76-0.96).

There are significant urban-rural inequalities in TBI in Japan, and the gap in in-hospital mortality has not improved over the last 10years. Improving TBI care in rural communities may be a target for reducing disparities in health care.

Primary mobile vertebral column sarcoma is an exceedingly rare malignancy. Although primary tumor resection has been reported to prolong survival in patients with metastatic bone sarcoma, whether primary tumor resection in patients with advanced primary mobile vertebral column sarcoma is associated with survival remains unclear owing to the rarity of this pathological entity.

Using the Surveillance, Epidemiology, and End Results database, 182 patients with metastatic primary mobile vertebral column sarcoma were identified between 1983 and 2015. Of the 182 patients enrolled, 101 patients (55%) underwent primary tumor resection (Surgery group) and 81 patients (45%) did not undergo resection (No Surgery group). To account for imbalances in the basic characteristics of patients between groups, propensity score matching was performed. Survival analysis was performed by weighted Cox proportional hazards modeling to calculate hazard ratios.

After adjusting for patient background characteristics, 138 patients were included for the analysis (Surgery group 69 patients; No Surgery group 69 patients). The Surgery group did not show improved cancer-specific survival (hazard ratio= 0.73, 95% CI 0.49-1.10). Similarly, the Surgery group did not show improved overall survival compared with the No Surgery group (hazard ratio= 0.80, 95% CI 0.55-1.16).

To our knowledge, this is the first study to indicate that surgical resection for advanced primary mobile vertebral column sarcoma does not have a positive impact on survival.

Sphenoid wing meningiomas with cavernous sinus invasion (SWMCSI) are challenging tumors. The preservation of quality of life and cranial nerve function is one of the most relevant aspects of treating patients with SWMCSI.

A retrospective study was conducted for surgery performed between 2008 and 2021, including 36 patients presenting with SWMCSI. The data from surgical intervention, Simpson grade of resection, tumor location, and morbimortality related to the surgery was reviewed. We examined the medical records, operative reports, radiologic examinations, and follow-up information.

The group comprised 29 women and 7 men with an average age of 61 years (range, 31-87 years). The mean follow-up period was 75 months (range, 1-170 months). Simpson grade I and II resections were obtained in 80% of cases. The meningiomas were World Health Organization (WHO) grade 1 in 94% of cases, WHO grade 2 in 3%, and WHO grade 3 in 3%. The overall mortality was 5.5%. Permanent cranial nerve deficits occurred in 8% of cases, transient cranial nerve deficits in 22%, cerebrospinal fistula in 16.5%, and hemiparesis in 2.7%. The recurrence/regrowth rate was 14% during the follow-up period. The Karnofsky Performance Status 100 and 90 was 92%.

The surgical treatment of symptomatic SWMCSI is an effective treatment modality with low morbimortality and good long-term control of the disease. Visual impairment is the most common abnormality, affecting preoperative and postoperative quality of life of patients with SWMCSI. Training in the microsurgical laboratory is essential for safe surgical approaches in this area.

While there are several reports on the impact of smoking tobacco on spinal fusion outcomes, there is minimal literature on the influence of modern smoking cessation therapies on such outcomes. Our study explores the outcomes of single-level lumbar fusion surgery in active smokers and in smokers undergoing recent cessation therapy.

MARINER30, an all-payer claims database, was utilized to identify patients undergoing single-level lumbar fusions between 2010 and 2019. The primary outcomes were the rates of any complication, symptomatic pseudarthrosis, need for revision surgery, and all-cause readmission within 30 and 90 days.

The exact matched population analyzed in this study contained 31,935 patients undergoing single-level lumbar fusion with 10,645 (33%) in each of the following groups (1) active smokers; (2) patients on smoking cessation therapy; and (3) those without any smoking history. Patients undergoing smoking cessation therapy have reduced odds of developing any complication following surgery (odds ratio 0.86, 95% confidence interval 0.80-0.93) when compared with actively smoking patients. Nonsmokers and patients on cessation therapy had a significantly lower rate of any complication compared with the smoking group (9.5% vs. 17% vs. 19%, respectively).

When compared with active smoking, preoperative smoking cessation therapy within 90 days of surgery decreases the likelihood of all-cause postoperative complications. However, there were no between-group differences in the likelihood of pseudarthrosis, revision surgery, or readmission within 90 days.

It has been proposed in the most recent 2021 World Health Organization classification of brain tumors that the loss of trimethylation at histone 3 lysine site 27 (H3K27me3) might prognosticate meningioma outcomes. However, to date, the emerging literature has remained diffuse in its stance. Thus, the aim of the present study was to determine the prognostic relevance of H3K27me3 loss in meningioma.

Searches of 7 electronic databases from inception to October 2021 were conducted in accordance with the PRISMA (preferred reporting items for systematic reviews and meta-analyses) guidelines. Articles were screened against prespecified criteria. Outcomes were pooled by random effects meta-analyses of proportions, where possible.

A total of 7 retrospective cohort studies satisfied all the criteria, with a total of 2180 meningioma patients overall (1291 male patients [59%]; mean age, 56 years). Across all 7 studies, the pooled incidence of H3K27me3 loss was estimated at 15% (95% confidence interval, 8%-24%). Across 6 studies, the pooled multivariate-derived hazard ratio estimate for recurrence was 1.77 (95% confidence interval, 1.23-2.31; P < 0.01). Overall survival on univariate analysis was significantly shorter with H3K27me3 loss in 2 of 4 studies (50%), and 2 studies had described a significant association between H3K27me3 loss and shorter overall survival on multivariate analysis.

The contemporary metadata favor a greater incidence of meningioma recurrence based independently on H3K27me3 loss, with a statistically significant difference. It is possible that these effects are more pronounced for grade 2 meningiomas; however, more robust data and analysis are needed to augment this position.

Central nervous system tumors encompass the leading cause of cancer-related death in the pediatric population. Neuroendoscopic techniques have been optimized over the years, becoming an important tool for the management of brain tumors. Our study aims to review the indications for neuroendoscopic procedures and the feasibility of combined interventions.

This is a single-center, self-adjudicated, retrospective experience. Inclusion criteria consisted of pediatric patients (≤18years old) who underwent management of brain tumor or related diseases with the employment of neuroendoscopy.

A total of 47 patients undergoing 51 procedures met inclusion criteria. The mean age was 9.8±4.6 years, and the majority were female (55.3%). Common indications for endoscopic intervention were hydrocephalus management (n= 24; 16 endoscopic third ventriculostomies and 9 septostomies), tumor biopsy (n= 19), cyst fenestration (n= 16), and tumor resection (n= 9). In one third of the cases, combined interventions occurred during a single operative session. Hydrocephalus was successfully managed in 74.4% of cases; tumor biopsy confirmed the diagnosis in 95.8% of cases, and gross total resection was achieved in 88.9% of cases. Cyst fenestration required reintervention in 3 cases one case associated with initial cyst enlargement and 2 cases with the development of new tumor cysts separated from the originally fenestrated cyst. The overall complication rate was 6.3%, with only one major safety event, which was successfully managed.

To enhance validity and comparability within and across those studies, the use of normed pictures is recommended. Besides, creating picture sets and evaluating them in rating studies is very time consuming, in particular regarding samples of young children in which testing time is rather limited. As there is an increasing number of studies that investigate young German children’s semantic language processing with colored clipart stimuli, this work provides a first set of 247 colored cliparts with ratings of German native speaking children aged 4 to 6 years. We assessed two central rating aspects of pictures Name agreement (Do pictures elicit the intended name of an object?) and semantic categorization (Are objects classified as members of the intended semantic category?). Our ratings indicate that children are proficient in naming and even better in semantic categorization of objects, whereas both seems to improve with increasing age of young childhood.
