The interaction of age, sex, and outcomes of children with head injury remains incompletely understood and these factors need rigorous evaluation in prognostic models for pediatric head injury. We leveraged our large institutional pediatric TBI population to evaluate age and sex along with a series of predictive factors used in the acute care of injury to describe the response and outcome of children and adolescents with moderate to severe injury. We hypothesized that younger age at injury and male sex would be associated with adverse outcomes and that a novel GCS-based scale incorporating pupillary response (GCS-P) would have superior performance in predicting 6-month outcome. GCS and GCS-P along with established CT scan variables associated with neurologic outcomes were retrospectively reviewed in children (age birth to 18 years) with moderate or severe head injury. GOS-E was prospectively collected 6 months after injury; 570 patients were enrolled in the study, 520 with TBI and 50 with abusive head trauma, each analyzed separately. In the TBI cohort, the median age of patients was 8 years and 42.7% had a severe head injury. Multiple predictors of outcome were identified in univariate analysis; however, based on a multivariate analysis, the GCS was identified as most reliable, outperforming GCS-P, pupil score, and other clinical and CT scan predictors. After stratifying patients for severity of injury by GCS, no age- or sex-related effects were observed in our patient population, except for a trend toward worse outcomes in the neonatal group. Patients with abusive head trauma were more likely to have severe injury on presentation, increased mortality rate, and unfavorable outcome. Additionally, there was clear evidence that secondary injuries, including hypoxia, hypotension, and hypothermia were significantly associated with lower GCS and higher mortality in both AHT and TBI populations. Our findings support the use of GCS to guide clinical decision-making and prognostication in addition to emphasizing the need to stratify head injuries for severity when undertaking outcome studies. Finally, secondary injuries are a clear predictor of poor outcome and how we record and manage these events need to be considered moving forward.

Background: Meningiomas are more prevalent in women and mostly benign in nature. Our aim was to evaluate the association of weight and outcomes of meningioma patients undergoing craniotomy. Methods: A retrospective analysis of meningioma patients discharged postcraniotomy between 1998 and 2007 was conducted. Univariate and multivariate analysis evaluated in‑hospital mortality, complications, length of stay (LOS), and cost. Results: According to the nationwide inpatient sample (NIS) database, an estimated 72,257 adult meningioma patients underwent a craniotomy in US hospitals during the study period. Female and male weight loss rates were 0.7% and 1.2%, respectively; obesity rates were 5.2% and 3.7%. Males had higher rates of malignant tumors than females (6.2% vs. 3.5%, P < 0.0001), and malignant tumors were more common in patients with weight loss (6.4% vs. 4.3%, P = 0.03). Weight loss was associated with higher mortality in men (OR 6.66, P < 0.0001) and women (OR 3.92, P = 0.04) as well as higher rates of postoperative complications in both men (OR 6.13, P < 0.0001) and women (OR 8.37, P < 0.0001). Furthermore, patients suffering weight loss had longer LOS and higher overall hospital cost when compared with all patients. In contrast, obesity seemed to reduce mortality (OR 0.47, P = 0.0006) and complications (OR 0.8, P = 0.0007) among women. Conclusions: In summary, weight loss seems to be the single most critical factor present in patients experiencing higher mortality, complications, hospital charges, and longer LOS. However, further studies aimed to assess the inter‑relation of potential preexisting comorbidities and weight loss are needed to establish causation. [ABSTRACT FROM AUTHOR]

Study Design: Retrospective population-based database analysis from the Physician/Supplier Procedure Summary Medicare/Medicaid Data Set., Objective: To provide a comprehensive analysis of trends in spinal orthosis utilization over a 12-year period., Summary of Background Data: Widespread prescription of spinal orthosis persists, despite evidence suggesting equivocal efficacy in many spinal conditions. The utilization of spinal orthosis on a national level, including prescribing specialty data, has not been previously analyzed., Materials and Methods: Health care common procedure coding system codes for cervical (CO), thoracic-lumbar-sacral (TLSO), lumbar (LO), lumbar-sacral (LSO), and cervical-thoracic-lumbar-sacral (CTLSO) orthosis were used to determine spinal orthosis utilization from 2010 to 2021. Provider specialty codes were utilized to compare trends between select specialties. In addition, a neurosurgical CO analysis based on subclassifications of cervical bracing was performed. Linear trendlines were implemented to elucidate and present trends by slope (β)., Results: Among 332,241 claims, decreases in CO (β=-0.3387), TLSO (β=-0.0942), LO (β=-0.3485), and LSO (β=-0.1545) per 100,000 Medicare Part B enrollees and CTLSO (β=-0.052) per 1,000,000 Medicare Part B enrollees were observed. Decreases among neurosurgery (β=-7.9208), family medicine (β=-1.0097), emergency medicine (β=-2.1958), internal medicine (β=-1.1151), interventional pain management (β=-5.0945), and chiropractic medicine (β=-49.012), and increases among orthopedic surgery (β=5.5891), pain management (β=30.416), physical medicine and rehabilitation (β=4.6524), general practice (β=79.111), and osteopathic manipulative medicine (β=45.303) in total spinal orthosis use per 100,000 specialty claims were observed. Analysis of subclassifications of cervical orthosis among neurosurgeons revealed decreases in flexible (β=-1.7641), semirigid (β=-0.6157), and collar bracing (β=-2.7603), and an increase in multipost collar bracing (β=2.2032) per 100 neurosurgical cervical orthosis claims., Conclusions: While utilization of spinal orthosis decreased between 2010 and 2021, increased utilization was observed among a subset of specialties. Identifying these specialties allows for focused research and educational efforts to minimize unnecessary durable medical equipment use for effective health care spending., Competing Interests: The authors report no conflicts of interest., (Copyright © 2023 Wolters Kluwer Health, Inc.

Objective: Selecting C2 versus C3 or C4 (i.e., C3/C4) as the rostral anchoring level in long-segment cervical fusions is a common clinical conundrum. The data regarding proximal failure in long constructs of the cervical spine is scarce. The objective of this study was to systematically review the published literature and perform a meta-analysis of the incidence for proximal adjacent-segment disease (ASD) in the context of long cervical fusions and cervicothoracic fusions ending in C2 versus those ending in the subaxial spine (C3 or C4)., Methods: Using the PRISMA guidelines, the authors performed a search of the PubMed/MEDLINE, Embase/Ovid, and Cochrane Central databases to identify all full-text articles in the English-language literature with the following inclusion criteria: 1) studies including patients with the upper instrumented vertebra (UIV) at C2 versus C3/C4; 2) patients undergoing ≥ 3-level posterior cervical fusion; and 3) indication for surgery of degenerative disc disease, cervical spondylotic myelopathy, or cervical deformity. Studies that were not published in the English language, case reports, review articles, letters to the editor, and meeting abstracts were excluded. A meta-analysis was conducted using a fixed-effects model when I2 values were below 70%. Conversely, when I2 values were equal to or greater than 70%, a random-effects model was used. A funnel plot was used to assess the presence of publication bias., Results: Seven studies consisting of 1215 patients were included in the meta-analysis. There were 403 (32.8%) patients in the C2 UIV group and 812 (67.2%) patients in the C3/C4 UIV group. When the 7 studies were analyzed, the overall rate of reoperation was comparable between the C2 (9.2%) and C3/C4 (9.4%) UIV groups (p = 0.93) but the rate of surgical ASD due to proximal pathology was 1.2% and 3%, respectively (OR 0.36, 95% CI 0.15-0.86; p = 0.02). When comparing between groups, no statistical difference was found regarding the rate of reoperation due to distal pathology or surgical infection., Conclusions: Long-segment cervical or cervicothoracic constructs that anchor into C2 may have similar complication rates but lower revision rates for proximal ASD than constructs that anchor into the subaxial spine.

Background and Purpose: Expeditious treatment is critical in patients with aneurysmal subarachnoid hemorrhage (aSAH) due to the risk of rebleeding. This study aimed to define predictors of treatment delay among aSAH patients., Methods: A retrospective study of the Nationwide Inpatient Sample database identified patients diagnosed with SAH between 2002 and 2007. Patient's characteristics such as age, gender, race, insurance, SAH severity, treatment (coil versus clip), and other factors were studied. The Cochrane-Armitage test was used to assess delayed care trends by procedure, time of treatment, and hospital volume. Multivariate logistic regression evaluated factors associated with treatment delays., Results: A total of 38,827 patients were admitted between 2002 and 2007; 69.0% were women and 61% were white. The overall median age was 52 years. More patients underwent treatment with surgical clipping than with endovascular coiling (60.4% versus 39.6%, respectively). Overall, 74% of hospital admissions occurred on weekdays; the remaining 26% occurred on weekends. Multivariate analysis revealed that older age (odds ratio [OR]: 1.1; p = 0.0004) and surgical clipping versus endovascular coiling (OR: 1.3; p = 0.02) were independent predictors of delayed treatment (i.e., >2 days from admission). Nonwhite patients experienced greater treatment delays on weekdays compared with white patients (OR: 1.4; p = 0.01). Furthermore, patients treated in low-volume hospitals were significantly more likely to experience delays than those treated in higher volume hospitals (OR: 2.0; p = 0.007)., Conclusions: Risk factors associated with treatment delay in aSAH patients include older age, nonwhite race, surgical clipping, and admission to low surgical volume hospitals., (Georg Thieme Verlag KG Stuttgart · New York.)
