Summary: According to the latest ILAE definition, status epilepticus can lead to long-term irreversible consequences, including neuronal death, neuronal injury, and alterations in neuronal networks. Therefore, there is growing interest in identifying biomarkers that can demonstrate and quantify the extent of neuro-glial injury. Although numerous studies have been conducted on animal models, evidence in humans is limited to case reports and small case series. The identification of these biomarkers in clinical practice can have significant implications, such as improved prognostic stratification and early identification of at-risk patients.

Summary: This study analyzed the levels of UCH-L1, GFAP, and NF-L in the serum of 153 patients without HIV and found that these proteins showed good diagnostic performance for neurosyphilis. The levels of these proteins in the serum correlated with those in CSF and had similar or better diagnostic performance. Therefore, these proteins could serve as biomarker candidates for neurosyphilis diagnosis without the need for lumbar puncture.

Summary: Unresolved issues related to blood biomarkers after mild traumatic brain injury (mTBI) are mainly focused on the pathways of biomarkers entering and exiting the blood, the kinetics of blood biomarkers, and the predictive capacity of blood biomarkers after mTBI. Further research is needed to address these issues.

Summary: S100B showed optimal sensitivity and specificity at a threshold of 0.72 μg/L, while GFAP demonstrated 71% sensitivity and specificity at 626 pg/mL, with sensitivity peaking at 93% at 22 pg/mL. Further investigation is needed to explore the potential advantages of GFAP in the screening of mild TBI.

Summary: The study investigated the clinical prognostic value of markers of neural tissue damage in predicting survival or transfer to ICU in patients infected with COVID-19. Results showed that certain markers were significantly increased in patients with fatal outcomes or needing ICU transfer, with total tau levels accurately predicting mortality. Blood neural markers may offer additional prognostic value for predicting COVID-19 outcomes.

Summary: CSF UCH-L1, GFAP, and NF-L can serve as novel markers for the diagnosis of neurosyphilis. They exhibit high sensitivity and specificity for NS diagnosis with specific cut-off points. Furthermore, they show weak or moderate correlations with CSF RPR, WBC, and protein, and can be used independently of these markers.

Summary: This study examined the changes in brain injury biomarker concentrations in different types of football athletes and found that players in speed and Profile 1 positions had the highest concentrations of GFAP, Tau, and NF-L, while players in non-speed and Profile 3 positions had the lowest concentrations.

Summary: Concussions, or mild traumatic brain injuries (mTBI), pose a growing health challenge. This study applies data-driven decision support to cluster blood biomarker trajectories in mTBI patients, providing improved tools for assessment and prediction. The ability to cluster these trajectories enhances the possibilities for precision medicine approaches to mTBI.

Summary: The prognostic value of GFAP and UCH-L1 as predictors of functional outcome after traumatic brain injury is significant. GFAP and UCH-L1 have good to excellent prognostic value for predicting death and unfavorable outcome, but not for predicting incomplete recovery at 6 months. These biomarkers contribute the most prognostic information for participants with a GCS score of 3-12.

Summary: Traumatic brain injury (TBI) is a major cause of mortality and morbidity across all ages, yet there is no FDA-approved drug for treatment. The heterogeneity and complexity of TBI make accurate assessment and prediction challenging. Biomarkers such as ubiquitin C-terminal hydrolase-L1 and glial fibrillary acidic protein have been identified to improve diagnostic accuracy, especially in mild TBI cases.

Summary: This study aimed to assess the predictive ability of ubiquitin C-terminal hydrolase L1 (UCH-L1) and total Tau (T-Tau) in determining the need for neurosurgical intervention and neurological outcome in patients with acute mild to moderate traumatic brain injury (TBI). The results showed that both UCH-L1 and T-Tau levels were significantly higher in TBI patients who required neurosurgical intervention and had a poor outcome. However, T-Tau was found to be a more accurate prognostic biomarker for TBI.

Summary: This manuscript discusses the development of patient-specific total TMJ prostheses. The design is based on medical images of the patient's TMJ, offering accurate anatomical fit and better fixation to the host bone. The prostheses have special features that potentially improve osseo-integration and durability. The design process takes into account surgeon's requirements, feedback, and pre-surgical planning to ensure accurate and clinically viable device design. The design is evaluated using FE modeling and analysis to investigate stress and strain profiles during TMJ loading scenarios.

Summary: Accurately evaluating reliability and addressing uncertainties in material response are crucial for extending the service life of components beyond historical limits. A probabilistic method has been developed and applied to predict the total fatigue life of a Ti-6Al-4V turbine disk component, taking into account both crack initiation and propagation mechanisms, as well as considering the uncertainties in material response using a microstructure-based model. The predictions of fatigue life have been validated against experimental data, particularly at high stress levels, and the risk assessment can be used to estimate initial crack sizes for enhanced inspection planning.

Summary: This study aims to understand the mechanical behavior and structural properties of human mandibles, as well as diagnose and develop treatment options for mandibular disorders. Experimental and computational finite element analysis (FEA) methods were used to investigate the surface strains in cadaveric human mandibles under different compressive loads. The results showed a good correlation between experimental measurements and FE predictions, indicating the validity and accuracy of the subject-specific FE models for evaluating the biomechanical behavior of human mandibles.

Summary: This retrospective study aimed to measure the in vivo damage resulting from revision surgery on glenoid liners. The study found that embedded debris was the most underrated damage mode, followed by pitting and abrasion. These damages may cause morphological changes in the microstructure and lead to premature failure of the liners.

Summary: The purpose of this study was to evaluate the force and torque required to dissociate a humeral head from different manufacturers' unimplanted modular total shoulder replacement system and to determine if load and torque to dissociation are reduced in the presence of bodily fluids. The study found that the dissociation force was greater than the force exerted by daily activities and wetting the taper did not significantly reduce the dissociation force. Torque and lack of compressive forces at the rotator cuff may be the cause of dissociation.
