National Taiwan University Hospital Hsin-Chu Branch Hsin-Chu Hospital, Taiwan. Electronic address:
Background: The prone position is commonly used in surgical procedures and is known to cause significant hemodynamic changes, particularly a reduction in cardiac output. This study aimed to explore the relationship between intra-abdominal pressure (IAP), airway pressure, and cardiac output during spine surgeries under general anesthesia.
Methods: Twenty-five patients undergoing elective spine surgery in the prone position were enrolled in this prospective observational study.
First-in-human experience performing high-resolution cortical mapping using a novel microelectrode array containing 1,024 electrodes.

Localization of function within the brain and central nervous system is an essential aspect of clinical neuroscience. Classical descriptions of functional neuroanatomy provide a foundation for understanding the functional significance of identifiable anatomic structures. However, individuals exhibit substantial variation, particularly in the presence of disorders that alter tissue structure or impact function.

Background: Type A aortic dissection (TAAD) remains a significant challenge in cardiac surgery, presenting high risks of adverse outcomes such as permanent neurological dysfunction and mortality despite advances in medical technology and surgical techniques. This study investigates the use of quantitative electroencephalography (QEEG) to monitor and predict neurological outcomes during the perioperative period in TAAD patients.
Methods: This prospective observational study was conducted at the hospital, involving patients undergoing TAAD surgery from February 2022 to January 2023.
The ketamine chameleon: history, pharmacology, and the contested value of experience.

Department of Psychiatry, McGill University, Montréal, Canada.
Introduction: Since its synthesis in 1962, ketamine has been widely used in diverse medical contexts, from anesthesia to treatment-resistant depression. However, interpretations of ketamine's subjective effects remain polarized. Biomedical frameworks typically construe the drug's experiential effects as dissociative or psychotomimetic, while psychedelic paradigms emphasize the potential therapeutic merits of these non-ordinary states.
