We explore the biology of iNSCs, their mechanisms of action, and their interactions with host tissue, including modulating inflammatory responses, promoting axonal growth, and reconstructing neural circuits.

Surgical and Neurointensive Management for Acute Spinal Cord Injury: A Narrative Review.

Spinal cord injury (SCI) following high-energy trauma often leads to lasting neurologic deficits and severe socioeconomic impact. Effective neurointensive care, particularly in the early stages post-injury, is essential for optimizing outcomes. This review discusses the role of neurointensive care in managing SCI, emphasizing early assessment, stabilization, and intervention strategies based on recent evidence-based practices.

Using Artificial Intelligence in the Comprehensive Management of Spinal Cord Injury.

Spinal cord injury (SCI) frequently results in persistent motor, sensory, or autonomic dysfunction, and the outcomes are largely determined by the location and severity of the injury. Despite significant technological progress, the intricate nature of the spinal cord anatomy and the difficulties associated with neuroregeneration make full recovery from SCI uncommon. This review explores the potential of artificial intelligence (AI), with a particular focus on machine learning, to enhance patient outcomes in SCI management.

Spinal Cord Injury From Tuberculous Spondylitis Misdiagnosed as Metastatic Spinal Tumor and Bacterial Spondylitis: A Case Report & Literature Review.

Tuberculous (TB) spondylitis, also known as Pott's disease, was first described by Percivall Pott in 1779. The diagnosis of TB spondylitis is often delayed because of the non-specific nature of the infection, which can lead to severe consequences. Differential diagnosis is especially critical in cancer patients undergoing chemotherapy who present with lymph node or bone metastasis.

Radiofrequency Ablation for Recurrent Thyroid Cancers: 2025 Korean Society of Thyroid Radiology Guideline.

Radiofrequency ablation (RFA) is a minimally invasive treatment modality used as an alternative to surgery in patients with benign thyroid nodules, recurrent thyroid cancers (RTCs), and primary thyroid microcarcinomas. The Korean Society of Thyroid Radiology (KSThR) initially developed recommendations for the optimal use of RFA for thyroid tumors in 2009 and revised them in 2012 and 2017. As new meaningful evidence has accumulated since 2017 and in response to a growing global interest in the use of RFA for treating malignant thyroid lesions, the task force committee members of the KSThR decided to update the guidelines on the use of RFA for the management of RTCs based on a comprehensive analysis of current literature and expert consensus.

A novel technique of blindly positioning bronchial blockers for one-lung ventilation: a prospective, randomized, crossover study.

Background: Several methods for blindly positioning bronchial blockers (BBs) for one-lung ventilation (OLV) have been proposed. However, these methods do not reliably ensure accurate positioning and proper direction. Here, we developed a clinically applicable two-stage maneuver by modifying a previously reported one-stage maneuver for successful insertion of a BB at the appropriate depth and direction in patients requiring lung isolation where a flexible bronchoscope (FOB) is not applicable.

Maintenance therapy with a P2Y12 receptor inhibitor after cangrelor in patients with acute coronary syndrome. The ELECTRA-SIRIO 2 investigators' viewpoint.

According to the ESC guidelines, cangrelor may be considered in P2Y12-inhibitor-naïve acute coronary syndrome (ACS) patients undergoing percutaneous coronary intervention (PCI). The aim of this review is to summarize available evidence on the optimal maintenance therapy with P2Y12 receptor inhibitor after cangrelor. Transitioning from cangrelor to a thienopyridine, but not ticagrelor, can be associated with a drug-drug interaction (DDI); therefore, a ticagrelor loading dose (LD) can be given any time before, during, or at the end of a cangrelor infusion, while a LD of clopidogrel or prasugrel should be administered at the time the infusion of cangrelor ends or within 30 minutes before the end of infusion in the case of a LD of prasugrel.
