RÉSUMÉ

This study examines the emerging role of biomarkers in the prognosis and management of severe traumatic brain injury (sTBI). Key findings highlight the significance of serum RIP-3, STC1, Nrf2, and cerebrospinal fluid galectin-3 and cytokines in predicting disease severity, mortality, and functional outcomes in sTBI patients. Elevated levels of RIP-3 and STC1 were linked to poor prognosis and increased mortality, with RIP-3 associated with necroptosis and inflammation, and STC1 with neuroprotective properties. Nrf2 was found to correlate with oxidative stress and adverse outcomes, while elevated CSF galectin-3 and IL-6 indicated neuroinflammation and neurodegeneration. These biomarkers show promise not only as prognostic tools but also as potential therapeutic targets. The study suggests further validation through multicenter research to enhance clinical applications and improve treatment strategies for sTBI.

RÉSUMÉ

This study evaluates contemporary wound closure techniques in spinal surgery, focusing on the efficacy of barbed sutures, skin staples, and negative-pressure wound therapy (NPWT), compared to traditional methods. Barbed sutures, like STRATAFIX™ Symmetric, and skin staples demonstrate significant advantages, including reduced wound closure time, lower infection rates, and improved surgical outcomes, particularly in multilevel or revisional procedures. In contrast, plastic surgery closures do not show a substantial reduction in postoperative complications despite being used in more complex cases. NPWT is highlighted as an effective adjunct therapy for managing surgical site infections and reducing the need for hardware removal. The findings suggest that while modern techniques offer clear benefits, traditional methods remain valuable in specific contexts. The review advocates for further research through large-scale, long-term studies and emphasizes the need for personalized wound closure strategies based on individual patient risk factors.

RÉSUMÉ

This study reviews lateral ventricular tumors (LVTs), which are rare brain lesions accounting for 0.64-3.5% of brain tumors, and the unique challenges they present due to their location and growth patterns. Once deemed inoperable, advancements in microneurosurgery, imaging, and tumor pathobiology have significantly improved treatment outcomes. This letter summarizes recent studies and key findings in the management of LVTs. Research by S.A. Maryashev et al. identified risk factors for early hemorrhagic complications following the surgical resection of lateral ventricular neoplasms, highlighting the significance of patient characteristics, tumor location, and surgical approach. The study found that factors such as gender, hydrocephalus, tumor blood flow, and Evans index correlate with a higher risk of hemorrhage, with the transcallosal approach having a greater risk compared to the transcortical approach. The utilization of navigation technologies, including fMRI, neuronavigation, and intraoperative brain mapping, has been shown to reduce surgical complications and enhance patient outcomes in the treatment of lateral ventricular meningiomas. Moreover, endoscopic and endoport-assisted endoscopic techniques have proven to be valuable in intraventricular tumor surgery, enabling minimally invasive procedures with better visualization and fewer complications. The integration of advanced surgical techniques, neuroimaging, and neurophysiological monitoring emphasizes the necessity of a multidisciplinary approach to optimize patient outcomes. To improve the study's validity and applicability, further research with larger sample sizes and advanced statistical analyses is needed. This letter advocates for the continued exploration of innovative surgical techniques and technologies to enhance the management of lateral ventricular tumors.

RÉSUMÉ

Spinal surgery, crucial for correcting structural abnormalities, involves decompressing nerve structures, realigning or stabilizing vertebral segments, and replacing damaged components to restore spinal integrity. Effective wound closure is vital in these procedures, as it prevents infections, minimizes wound dehiscence, and ensures optimal cosmetic results. Recent advancements, particularly in barbed suture technology like STRATAFIX™ Symmetric, offer promising improvements in surgical outcomes. A study by Steven R. Glener et al. evaluated STRATAFIX™ Symmetric for fascial closure in spinal surgery, comparing it to traditional braided absorbable sutures. Although the difference in closure time was not statistically significant, STRATAFIX™ demonstrated a higher closure rate and required significantly fewer sutures, reducing post-surgical material counts and the risk of accidental needle sticks. No adverse events were observed in either group over a 6-month follow-up period. Despite their benefits in reducing operating room time and costs, barbed sutures remain underutilized in neurosurgery. Studies indicate that barbed sutures can significantly decrease wound closure time, particularly in complex or multilevel spinal surgeries, without compromising clinical outcomes. These findings suggest that adopting barbed suture technology in spinal surgery could enhance surgical efficiency and patient care. Further research with larger sample sizes and multicenter studies is necessary to validate these benefits and refine surgical practices, ultimately improving patient outcomes.

RÉSUMÉ

This study reviews recent progress in the surgical treatment of Rathke's cleft cysts (RCCs) and Sellar region meningiomas, based on findings from three key studies. RCCs are benign, fluid-filled remnants from pituitary gland development that are usually asymptomatic and found by chance. However, surgical intervention is needed when they become symptomatic or increase in size. Research by Stefan Linsler et al. and others examines various surgical methods, including transcranial keyhole and transsphenoidal techniques for RCCs, and endoscopic endonasal and supraorbital keyhole approaches for Sellar meningiomas. The results show that both transcranial keyhole and transsphenoidal surgeries for RCCs have high success rates with no recurrences over 5.7 years, although the keyhole approach has fewer complications. For Sellar meningiomas, the choice between endoscopic endonasal and supraorbital keyhole techniques should be based on tumor characteristics, highlighting the importance of surgeon proficiency in both methods. These studies emphasize the need for personalized treatment strategies tailored to patient and tumor characteristics and highlight the importance of ongoing surgical skill development and further research to refine minimally invasive techniques. This study highlights the crucial role of personalized surgical approaches in improving outcomes for patients with RCCs and Sellar region meningiomas.

RÉSUMÉ

The study highlights that diffuse glioma, a prevalent type of brain tumor, affect approximately 100,000 individuals worldwide each year. IDH-mutant astrocytoma and oligodendrogliomas typically have a more favorable prognosis compared to IDH-wildtype glioblastomas. However, many IDH-mutant astrocytoma has the potential to progress to grade 4 glioblastomas, leading to a less favorable prognosis. In a recent investigation, Shumpei Onishi et al. examined the T2-FLAIR mismatch sign as a possible imaging biomarker for assessing CDKN2A status in non-enhancing IDH-mutant astrocytoma. The findings indicate that the T2-FLAIR mismatch sign is linked to CDKN2A-intact astrocytoma, providing a valuable tool for diagnostic and prognostic purposes. Additionally, the use of Indocyanine Green (ICG) for real-time visualization during neurosurgical procedures demonstrates potential, though it may have limitations in specificity. While these advancements offer promise in glioma management, there remains a critical need for larger, standardized studies to validate these findings and further improve treatment outcomes.

RÉSUMÉ

Creating an innovative and environmentally friendly energy storage system is of vital importance due to the growing number of environmental problems and the fast exhaustion of fossil fuels. Energy storage using porous carbon composites generated from biomass has attracted a lot of attention in the research community. This is primarily due to the environmentally friendly nature, abundant availability in nature, accessibility, affordability, and long-term viability of macro/meso/microporous carbon sourced from a variety of biological materials. Extensive information on the design and the building of an energy storage device that uses supercapacitors was a part of this research. This study examines both porous carbon electrodes (ranging from 44 to 1050 F/g) and biomasses with a large surface area (between 215 and 3532 m2/g). Supposedly, these electrodes have a capacitive retention performance of about 99.7 percent after 1000 cycles. The energy density of symmetric supercapacitors is also considered, with values between 5.1 and 138.4 Wh/kg. In this review, we look at the basic structures of biomass and how they affect porous carbon synthesis. It also discusses the effects of different structured porous carbon materials on electrochemical performance and analyzes them. In recent developments, significant steps have been made across various fields including fuel cells, carbon capture, and the utilization of biomass-derived carbonaceous nanoparticles. Notably, our study delves into the innovative energy conversion and storage potentials inherent in these materials. This comprehensive investigation seeks to lay the foundation for forthcoming energy storage research endeavors by delineating the current advancements and anticipating potential challenges in fabricating porous carbon composites sourced from biomass.

RÉSUMÉ

The development of green hydrogen generation technologies is increasingly crucial to meeting the growing energy demand for sustainable and environmentally acceptable resources. Many obstacles in the advancement of electrodes prevented water electrolysis, long thought to be an eco-friendly method of producing hydrogen gas with no carbon emissions, from coming to fruition. Because of their great electrical conductivity, maximum supporting capacity, ease of modification in valence states, durability in hard environments, and high redox characteristics, transition metal oxides (TMOs) have recently captured a lot of interest as potential cathodes and anodes. Electrochemical water splitting is the subject of this investigation, namely the role of transition metal oxides as both active and supportive sites. It has suggested various approaches for the logical development of electrode materials based on TMOs. These include adjusting the electronic state, altering the surface structure to control its resistance to air and water, improving the flow of energy and matter, and ensuring the stability of the electrocatalyst in challenging conditions. In this comprehensive review, it has been covered the latest findings in electrocatalysis of the Oxygen Evolution Reaction (OER) and Hydrogen Evaluation Reaction (HER), as well as some of the specific difficulties, opportunities, and current research prospects in this field.

RÉSUMÉ

In recent years, a new class of highly crystalline advanced permeable materials covalent-organic frameworks (COFs) have garnered a great deal of attention thanks to their remarkable properties, such as their large surface area, highly ordered pores and channels, and controllable crystalline structures. The lower physical stability and electrical conductivity, however, prevent them from being widely used in applications like photocatalytic activities and innovative energy storage and conversion devices. For this reason, many studies have focused on finding ways to improve upon these interesting materials while also minimizing their drawbacks. This review article begins with a brief introduction to the history and major milestones of COFs development before moving on to a comprehensive exploration of the various synthesis methods and recent successes and signposts of their potential applications in carbon dioxide (CO2 ) sequestration, supercapacitors (SCs), lithium-ion batteries (LIBs), and hydrogen production (H2 -energy). In conclusion, the difficulties and potential of future developing with highly efficient COFs ideas for photocatalytic as well as electrochemical energy storage applications are highlighted.

RÉSUMÉ

In recent times, industrialized economies have focused more on achieving a sustainable environment while maintaining economic prosperity. However, it is clear from the current research that natural resource exploitation and decentralization substantially affect environmental quality. To experimentally validate such data, the current study examines decentralized economies during the previous three decades (1990-2020). This study discovered the existence of long-term cointegration between carbon emissions, economic growth, revenue decentralization, spending decentralization, natural resources, and human capital using panel data econometric techniques. The findings are based on non-parametric techniques, indicating that economic growth and revenue decentralization are the primary barriers to meeting the COP26 objective. Human capital drives down carbon emissions and contributes to meeting the COP26 objective. On the contrary, decentralization of spending and natural resources has a mixed influence on carbon emissions across quantiles. This report recommends investing in human capital, education, and research & development to speed up COP26's target accomplishment.

RÉSUMÉ

Due to the uncertainty surrounding the coupling and decoupling of natural gas, oil, and energy commodity futures prices, the current study seeks to investigate the interactions between energy commodity futures, oil price futures, and carbon emission futures from a forecasting perspective with implications for environmental sustainability. We employed daily data on natural gas futures prices, crude oil futures prices, carbon futures prices, and Dow Jones energy commodity futures prices from January 2018 to October 2021. For empirical analysis, we applied machine learning tools including traditional multiple linear regression (MLR), artificial neural network (ANN), support vector regression (SVR), and long short-term memory (LSTM). The machine learning analysis provides two key findings. First, the nonlinear frameworks outperform linear models in developing the relationships between future oil prices (crude oil and heating oil) and carbon emission futures prices. Second, the machine learning findings establish that when oil prices and natural gas prices display extreme movement, carbon emission futures prices react nonlinearly. Understanding the nonlinear dynamics of extreme movements can help policymakers design climate and environmental policies, as well as adjust natural gas and oil futures prices. We discuss important implications to sustainable development goals mainly SDG 7 and SDG 12.
