Acute brain injury resulting from ischemic/hemorrhagic or traumatic damage is one of the leading causes of mortality and disability worldwide and is a significant burden to society. Neuroprotective options to counteract brain damage are very limited in stroke and traumatic brain injury (TBI). Given the multifaceted nature of acute brain injury and damage progression, several therapeutic targets may need to be addressed simultaneously to interfere with the evolution of the injury and improve the patient's outcome. Stem cells are ideal candidates since they act on various mechanisms of protection and repair, improving structural and functional outcomes after experimental stroke or TBI. Stem cells isolated from placenta offer advantages due to their early embryonic origin, ease of procurement, and ethical acceptance. We analyzed the evidence for the beneficial effects of placenta-derived stem cells in acute brain injury, with the focus on experimental studies of TBI and stroke, the engineering strategies pursued to foster cell potential, and characterization of the bioactive molecules secreted by placental cells, known as their secretome, as an alternative cell-free strategy. Results from the clinical application of placenta-derived stem cells for acute brain injury and ongoing clinical trials are summarily discussed.

Polyphenylalanine-Baicalein Nanomicelles Reduce Nerve Cell Apoptosis and Inflammation to Enhance Neuroprotection and Poststroke Rehabilitation.

School of Life Science, South China Normal University, Guangzhou 510631, China.
Cerebral ischemic stroke, neuronal death, and inflammation bring difficulties in neuroprotection and rehabilitation. In this study, we developed and designed the ability of natural lactoferrin-polyethylene glycol-polyphenylalanine-baicalein nanomicelles (LF-PEG-PPhe-Bai) to target and reduce these pathological processes, such as neurological damage and cognitive impairment in the stages of poststroke. Nanomicelles made from biocompatible materials have improved bioavailability and targeted distribution to afflicted brain areas.

Participants: Active duty service members (N = 75,730) with an initial mTBI diagnosis in military records between January 2011 and January 2018.
A case of severe TBI: Recovery?
Appl Neuropsychol Child
January 2025
Department of Psychology and Neuroscience Center, Brigham Young University, Provo, USA.
Chronic stage neuropsychological assessments of children with severe TBI typically center around a referral question and focus on assessing cognitive, behavioral, and emotional functioning, making differential diagnoses, and planning treatment. When severe TBI-related neurological deficits are subtle and fall outside commonly assessed behavioral indicators, as can happen with theory of mind and social information processing, they can go unobserved and subsequently fail to be assessed. Additionally, should chronic stage cognitive, behavioral, and emotional assessment findings fall within the average to above average range, a child experiencing ongoing significant unassessed severe TBI-related subtle deficits could be mistakenly judged to have "recovered" from their injury; and to be experiencing no significant ongoing residual neurological deficits.
