Neurocritical care
-
The use of multimodal neuromonitoring in pediatrics is in its infancy relative to adult neurocritical care. Multimodal neuromonitoring encompasses the amalgamation of information from multiple individual neuromonitoring devices to gain a more comprehensive understanding of the condition of the brain. It allows for adaptation to the changing state of the brain throughout various stages of injury with potential to individualize and optimize therapies. ⋯ The possible benefits of multimodal neuromonitoring are immense and have great potential to advance the field of pediatric neurocritical care and the health of critically ill children.

The advent of neurotechnologies including advanced functional magnetic resonance imaging and electroencephalography to detect states of awareness not detectable by traditional bedside neurobehavioral techniques (i.e., covert consciousness) promises to transform neuroscience research and clinical practice for patients with brain injury. As these interventions progress from research tools into actionable, guideline-endorsed clinical tests, ethical guidance for clinicians on how to responsibly communicate the sensitive results they yield is crucial yet remains underdeveloped. Drawing on insights from empirical and theoretical neuroethics research and our clinical experience with advanced neurotechnologies to detect consciousness in behaviorally unresponsive patients, we critically evaluate ethical promises and perils associated with disclosing the results of clinical covert consciousness assessments and describe a semistructured approach to responsible data sharing to mitigate potential risks.

Randomized Controlled Trial
Mechanistic Evaluation of Diffusion Weighted Hyperintense Lesions After Large Spontaneous Intracerebral Hemorrhage: A Subgroup Analysis of MISTIE III.
Ischemic lesions on diffusion weighted imaging (DWI) are common after acute spontaneous intracerebral hemorrhage (ICH) but are poorly understood for large ICH volumes (> 30 mL). We hypothesized that large blood pressure drops and effect modification by cerebral small vessel disease markers on magnetic resonance imaging (MRI) are associated with DWI lesions. ⋯ In patients with large hypertensive ICH, white matter disease, intraventricular hemorrhage volume, and large reductions in SBP over the first 24 h were independently associated with DWI lesions. Further investigation of potential hemodynamic mechanisms of ischemic injury after large ICH is warranted.

Traumatic brain injury (TBI) can cause rapid brain inflammation. There is debate over the safety and efficacy of anti-inflammatory agents in its treatment. With a particular focus on cyclooxygenase 2 (COX2) selective inhibition, we sought to determine the impact of celecoxib versus no celecoxib treatment on outcomes in patients with TBI and compare these with outcomes associated with nonselective COX inhibition (ibuprofen) and corticosteroid (dexamethasone) treatment. ⋯ Early celecoxib and ibuprofen use within 5 days post TBI was associated with higher 1-year survival probabilities and fewer complications. With emerging yet controversial preclinical evidence to suggest that COX inhibition improves TBI outcomes, this population-level study offers suggestive support for these drugs' clinical benefit, which should be pursued in prospective clinical studies.

The limited representation from developing countries in the original COME TOGETHER survey gave us an impetus to conduct this survey in the Indian subcontinent. ⋯ Differences from the global survey were noted regarding the following: traumatic brain injury being the most common etiology of coma in India, more frequent practice of sedation interruption, less frequent use of electroencephalography in India, rare use of pharmacological neurostimulants, and home being the most common discharge disposition in India.
