Traumatic Brain Injury (TBI) is a devastating cause of death and disability. Outcomes following TBI have been extensively studied; however, less attention has been given to identifying characteristics of individuals who have a favorable outcome following severe TBI. We conducted a retrospective analysis of a database containing information on TBI patients admitted to a level 1 trauma center between 2015 and 2021.

Neuronal dynamics of cerebellum and medial prefrontal cortex in adaptive motor timing.

Nat Commun

January 2025

Department of Neuroscience, Erasmus MC, Westzeedijk 353, 3015 AA, Rotterdam, the Netherlands.

Precise temporal control of sensorimotor coordination and adaptation is a fundamental basis of animal behavior. How different brain regions are involved in regulating the flexible temporal adaptation remains elusive. Here, we investigated the neuronal dynamics of the cerebellar interposed nucleus (IpN) and the medial prefrontal cortex (mPFC) neurons during temporal adaptation between delay eyeblink conditioning (DEC) and trace eyeblink conditioning (TEC).

Background: The oxygen reactivity index (ORx) reflects the correlation between focal brain tissue oxygen (pbtO) and the cerebral perfusion pressure (CPP). Previous, small cohort studies were conflicting on whether ORx conveys cerebral autoregulatory information and if it is related to outcome in traumatic brain injury (TBI). Thus, we aimed to investigate these issues in a larger TBI cohort.

Background Context: Correcting sagittal malalignment in adult spinal deformity (ASD) is a challenging task, often requiring complex surgical interventions like pedicle subtraction osteotomies (PSOs). Different types of three-column osteotomies (3COs), including Schwab 3, Schwab 4, Schwab 4 with interbody cages, and the "sandwich" technique, aim to optimize alignment and fusion outcomes. The role of interbody cages in enhancing fusion and segmental correction remains unclear.

Introduction: Brain damage caused by subarachnoid hemorrhage (SAH) currently lacks effective treatment, leading to stagnation in the improvement of functional outcomes for decades. Recent studies have demonstrated the therapeutic potential of exosomes released from mesenchymal stem cells (MSC), which effectively attenuate neuronal apoptosis and inflammation in neurological diseases. Due to the challenge of systemic dilution associated with intravenous administration, intranasal delivery has emerged as a novel approach for targeting the brain.

Hepatocellular carcinoma (HCC) is the primary malignancy affecting the liver and the leading cause of mortality among individuals with cirrhosis. This complex disease is associated with various risk factors, including environmental, pathological, and genetic influences, which dysregulate gene expression crucial for the cell cycle and cellular/molecular pathways. The disruption of the balance between tumor suppressors and proto-oncogenes amplifies the pathogenic cascade.

Introduction: Meningiomas are the most common primary central nervous system tumors, often requiring surgical resection. Presurgical embolization (PSE) is used to reduce intraoperative bleeding, although its effectiveness varies. This study evaluates the safety and efficacy of PSE using ethyl-vinyl alcohol (EVOH) in meningioma surgeries.

Objective: This study aims to comprehensively evaluate the complications, effectiveness, and safety of neuroendoscopic surgery (NS) assisted by 3DSlicer software, compared to traditional surgery in patients with intracerebral hemorrhage (IH).

Methods: We searched for case-control trials from the Chinese Biomedical Literature data (CBM) online database, Wanfang Database, EMBASE, VIP Full-text Database, China National Knowledge Infrastructure (CNKI), Science Direct, Cochrane Library, and PubMed. The studies, published since January 2010, involved NS or traditional surgery for IH patients assisted by 3DSlicer software.

Traumatic brain injury (TBI) can lead to chronic neuroinflammation, and neurodegeneration associated with long-term cognitive deficits. Following TBI, the acute neuroinflammatory response involves microglial activation and the release of proinflammatory cytokines and chemokines which induce the recruitment of peripheral immune cells such as monocytes and ultimately T cells. Persistent innate and adaptive immune cells response can lead to chronic neurodegeneration and functional deficits.

Background: Lesions affecting the brain are variable and have multiple pathologies. Brain metastasis is a common entity of lesions that can be misleading in diagnosis. Brain metastasis affects the patient's life and survival in about 40% of cases; all patients with metastatic brain lesions are indicated for surgery, so proper diagnosis is crucial for each patient.

3D printed titanium banana interbody cages versus titanium-coated PEEK bullet cages for TLIF.

Clin Neurol Neurosurg

January 2025

Department of Neurosurgery, The Ohio State University, 410 W 10th Ave, Columbus, OH 43210, United States.

Introduction: Lumbar degenerative spinal disease is a common, major cause of pain and disability. Titanium and polyetheretherketone (PEEK) are popular materials for interbody implants although evidence is mixed on which material is superior in terms of fusion and subsidence. The purpose of this study was to evaluate the clinical outcome of 3D printed titanium (3DPT) cages in patients undergoing TLIFs, as well as complication profiles based on widely used outcome metrics and reoperation events.

As an important element of the human body, iron participates in numerous physiological and biochemical reactions. In the past decade, ferroptosis (a form of iron-dependent regulated cell death) has been reported to contribute to the pathogenesis and progression of various diseases. The stability of iron in cardiomyocytes is crucial for the maintenance of normal physiological cardiac activity.

Introduction: Congenital lumbar kyphosis is present in about 15% of patients with myelomeningocele. Worsening of deformity with complications such as chronic skin ulcers and bone exposure is common. In patients under 8 years of age, treatment becomes even more challenging: in addition to resecting the apex of the kyphotic deformity, we should ideally stabilize the spine with fixation methods that do not interrupt the growth of the rib cage, associated with the challenging pelvic fixation in this population.
