A total of 62 children (aged <18 years) with cranial bone defects due to DC underwent CP with a custom-made PEEK at our department between January 2018 and April 2023. The clinical characteristics, radiological features, surgical conditions, postoperative complications, and follow-up results of these patients were analyzed retrospectively. Kaplan-Meier survival analysis and Cox regression were used to analyze data. The age of the patients ranged from 2 to 17 years. The follow-up periods ranged from 12 to 70 months. Six patients experienced subcutaneous fluid accumulation (9.7%), five experienced epidural fluid accumulation (8.1%), and two experienced scalp inflammation (3.2%), which all were cured before discharge. Seven patients experienced bone gap expansion at the interface between the cranial bone and PEEK during follow-up (11.3%). Univariate analysis showed that DC-CP time interval (<3 months) and age were two influencing factors. Multivariate analysis revealed that age was the most important factor (<i>p</i> < 0.005, hazard ratio = 0.250, 95% confidence interval: 0.096-0.652). No reoperation was performed. Medical follow-ups were carried out further. For pediatric patients with cranial defects after DC who receive CP with a custom-made PEEK, two variables including younger age and too short DC-CP time interval may be unfavorable factors, to make patients experience bone gap expansion at the interface between the cranial bone and the PEEK.

While studies have examined acute and chronic outcomes in young and deceased athletes, research on middle-aged former athletes remains limited. We employed multiplex biomarker approaches to examine whether brain injury and systemic inflammatory blood biomarkers are reflective of ≥10 years of participation in contact sports in retired, middle-aged amateur athletes. This cross-sectional study included a cohort of 41 former contact athletes (32 male, 9 female) and 22 age- and sex-matched noncontact athletes (14 male, 8 female). Blood biomarkers of brain injury, including glial fibrillary acidic protein, ubiquitin C-terminal hydrolase L1 (UCH-L1), tau, and neurofilament light (NfL), alongside 18 systemic inflammatory markers, were examined via linear regression models with age and concussion history as covariates. Our analyses revealed no significant differences in brain injury blood biomarkers between groups. However, increasing age was associated with increased NfL levels in contact athletes, while greater concussion history correlated with elevated UCH-L1 and tau in contact athletes only. Contact athletes exhibited significantly increased levels of systemic inflammatory markers, including IL-8, CCL-2, CCL-3, IL-2, VCAM-1, and S100B. While brain injury blood biomarkers did not differ between groups, the association between age, concussion history, and increased NfL, UCH-L1, and tau levels in the contact group suggests potential long-term neural consequences of repetitive head impacts. Elevated systemic inflammatory markers potentially highlight a chronic inflammatory response in former contact athletes, underscoring the need for continued monitoring and interventions to mitigate neurodegenerative risk.</p>","PeriodicalId":74300,"journal":{"name":"Neurotrauma reports","volume":"6 1","pages":"638-650"},"PeriodicalIF":1.8,"publicationDate":"2025-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12413257/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145016867","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this report was to summarize our experience of using the PFI in the Late Effects of TBI (LETBI) brain donor program to facilitate replication, expansion, and refinement of PFI methods in TBI brain donor programs.

We also compare the information captured in the PFI with data abstracted from the medical records for 34 decedents in the LETBI brain donor program to illustrate the complementarity of these approaches and highlight the unique contributions of the PFI. The PFI can provide granular details about a decedent's clinical history and symptom trajectories over time, potential contributing factors to PTND including social determinants of health (e.g., race and years of education), family history of medical and psychiatric conditions, and contextual information regarding cause(s) of death.

To determine patient death, we used death in a Penn Medicine facility and linkage to the Social Security Death Index.

Twenty-one adults with moderate and severe DAI were analyzed. Structural and diffusion data were acquired on a 3T system 3 and 6 months after the injury. The differences in cortical thickness, FA, and FW values over time were analyzed as factors for the phonemic and semantic VF scores between the 6th and 12th months following the DAI. All analyses were corrected for multiple comparisons. Cortical thickness increased over time in 7 of the 13 ROIs in the right hemisphere and 5 of the 13 ROIs in the left hemisphere. There was an increase in FA in the right arcuate fasciculus and the inferior longitudinal fasciculus over time. An increase in phonemic VF scores was detected between 6 and 12 months post-traumatic brain injury, but not in semantic VF scores over time. Cortical thickness changes in the left posterior inferior frontal pars opercularis and left anterior superior temporal sulcus from 3 to 6 months were associated with improved phonemic VF scores over time. There was no association between diffusion magnetic resonance imaging metrics and VF scores. Our findings suggest that brain plasticity plays a significant role in the initial year following traumatic brain injury, as evidenced by increased cortical thickness and white matter integrity.

While craniectomies are commonly used in TBI research, inadvertent dura disruption can result in structural deficits, impacting cellular function and neurobehavioral outcomes. Thus, there is a critical need to evaluate the effect of craniectomy on neurological outcomes to develop robust experimental controls and improve pre-clinical TBI research. In this study, craniectomy mice undergoing surgical and anesthetic intervention were assessed against naïve mice for neurological deficits and pathophysiological dysfunction. T2-weighted magnetic resonance imaging confirmed that no lesions or cavities were observed postcraniectomy. However, the cranial defect induced midline shifting over time, which might contribute to poorer behavioral outcomes in the novel object recognition assessment. Immunohistochemical analysis demonstrated an increase in GFAP and Iba1, indicating craniectomy elicited an inflammatory response. Indeed, neuroinflammation led to an increase in neuronal cell death, as measured by increases in α-II-spectrin breakdown products. However, craniectomy mice also presented with decreases in LC3BII and SQSTM1 expression, indicating an inhibition of autophagy. Last, craniectomy contributed to the altered expression of several tight junction proteins, including occludin and claudin-1/5, suggesting the blood-brain barrier was perturbed. Overall, the deficits associated with craniectomy preclude its use as an adequate sole control for TBI research, as craniectomy limits translational insights into the neurological changes observed in TBI.

However, there is limited assessment of whether head injury recall assessments produce consistent measures over time, and no assessment of whether the reporting is related to current health status. The concussion signs and symptoms scale (CSS; developed for the Football Players Health Study at Harvard University) was designed to measure cumulative head injury exposure history by asking about the frequency of 10 CSS during active football play. Responses are summed with a total CSS range of 0-130. Former professional American-style football players completed the CSS at two timepoints.

Participants completed a comprehensive assessment protocol for neurodegenerative disease, including magnetic resonance imaging (MRI), PET scans for tau and Aβ, blood draw, subjective symptom reports related to neurodegenerative disease, and objective neurocognitive assessment. Surveys included the Neurobehavioral Symptom Inventory (NSI), Insomnia Severity Index (ISI), Epworth Sleepiness Severity (ESS), PTSD Checklist for DSM-5 (PCL-5), Brief Symptom Inventory-18 (BSI-18), Satisfaction with Life Scale (SWLS), Barratt Impulsivity Scale (BIS), and Buss Perry Aggression Questionnaire (BPAQ). PET scans were read by a neuroradiologist and rated positive or negative based upon established cutoffs. General linear models compared participants with TBI history with controls on outcomes.
