Background: Major depressive disorder (MDD) poses a significant treatment challenge, with some patients unresponsive to conventional therapies. Electroconvulsive therapy (ECT) can be effective but its mechanisms are not fully understood. This study employs functional Near-Infrared Spectroscopy (fNIRS) to explore the neurobiological changes induced by ECT in A MDD patient, aiming to shed light on its therapeutic effects.
Purpose: This study employs fNIRS to assess differences between MDD patient and controls, and examines changes in cerebral hemodynamics and brain network nodes post-ECT to elucidate treatment mechanisms.
Methods: 26 age and gender-matched controls and one MDD male patient underwent fNIRS during a verbal fluency task. The patient received ECT, with dynamic evaluation of beta, integral, and centroid values in regions of interest (ROIs) post-treatment. Resting-state fNIRS and functional connectivity assessments were also conducted post-ECT.
Results: MDD patient exhibited significantly lower hemodynamic metrics and functional connectivity compared to controls at baseline. Post-ECT, dynamic changes in these metrics were observed, trending towards normalization and showing no significant differences from controls.
Conclusion: ECT modifies cerebral hemodynamics and functional connectivity in depressive patients, as evidenced by fNIRS metrics. This study underscores the utility of fNIRS for objective neurobiological monitoring in ECT treatment.

Objectives: The pathophysiological mechanisms of status epilepticus (SE) underlying potential brain injury remain largely unclear. This study aims to employ functional near-infrared spectroscopy (fNIRS) combined with video-electroencephalography (vEEG) to monitor brain hemodynamics continuously and non-invasively in critically ill adult patients experiencing electrographic SE. Our primary focus is to investigate neurovascular coupling and cerebrovascular changes associated with seizures, particularly during recurring and/or prolonged episodes.

Aim: Intraoperative lung-protective ventilation strategies (LPVS) have been shown to improve lung oxygenation and prevent postoperative pulmonary problems in surgical patients. However, the application of positive end-expiratory pressure (PEEP)-based LPVS in emergency traumatic brain injury (TBI) has not been thoroughly explored. The purpose of this study is to evaluate the effects of drive pressure-guided individualized PEEP on perioperative pulmonary oxygenation, postoperative pulmonary complications, and recovery from neurological injury in patients with TBI.

Background And Purpose: Malignant middle cerebral artery infarction (MMI) is a severe condition with a high mortality rate. While decompressive hemicraniectomy has been demonstrated to reduce mortality, there is limited knowledge regarding blood pressure (BP) management following the surgery. This study aimed to investigate whether early blood pressure variability after surgery is associated with functional outcomes.

Remote ischemic conditioning (RIC) has attracted considerable attention as a brain protection strategy, although its impact remains unclear. Hypothermia is the most effective strategy in experimental transient cerebral ischemia. Therefore, we compared the efficacy of RIC, hypothermia, and no treatment on cerebral ischemia.
