Observational StudyThe association between lactate to albumin ratio and outcomes at early phase in patients with traumatic brain injury.
The majority of traumatic brain injury (TBI) cases result in death in the early phase; predicting short-term progno-sis of affected patients is necessary to prevent this. This study aimed to examine the association between the lactate-to-albumin ratio (LAR) on admission and outcomes in the early phase of TBI. ⋯ LAR was associated with early-phase outcomes in patients with TBI, including 24-h mortality and MT. LAR may help predict these outcomes within 24 h in patients with TBI.

ReviewAdvances in Optogenetics Applications for Central Nervous System Injuries.
Injuries to the central nervous system (CNS) often lead to severe neurological dysfunction and even death. However, there are still no effective measures to improve functional recovery following CNS injuries. Optogenetics, an ideal method to modulate neural activity, has shown various advantages in controlling neural circuits, promoting neural remapping, and improving cell survival. ⋯ In this review, we introduce the light-sensitive proteins and light stimulation system that are important components of optogenetic technology in detail and summarize the development trends. In addition, we construct a comprehensive picture of the current application of optogenetics in CNS injuries and highlight recent advances for the treatment and functional recovery of neurological deficits. Finally, we discuss the therapeutic challenges and prospective uses of optogenetics therapy by photostimulation/photoinhibition modalities that would be suitable for clinical applications.

Predicting Mortality Following Traumatic Brain Injury or Subarachnoid Hemorrhage: An Analysis of the Validity of Standardized Mortality Ratios Obtained From the APACHE II and ICNARCH-2018 Models.
Standardized mortality ratios (SMRs), calculated using the Acute Physiology, Age, Chronic Health Evaluation II (APACHE II) and Intensive Care National Audit and Research Centre H-2018 (ICNARC H-2018 ) risk prediction models, are widely used in UK intensive care units (ICUs) to measure and compare the quality of critical care delivery. Both models incorporate an assumption of Glasgow Coma Score (GCS) if an actual GCS without sedation is not recordable in the first 24 hours after ICU admission. This study assesses the validity of the APACHE II and ICNARC H-2018 models to predict mortality in ICU patients with traumatic brain injury (TBI) or aneurysmal subarachnoid hemorrhage (aSAH) in whom GCS is related to outcomes. ⋯ The APACHE II and ICNARC H-2018 models predicted mortality well for the overall TBI/aSAH ICU population but underpredicted mortality when GCS was ≤8 or "unrecordable." This raises questions about the accuracy of these risk prediction models in TBI/aSAH patients and their use to evaluate treatments and compare outcomes between centers.

ReviewPutting the mind to rest: a historical foundation for rest as a treatment for traumatic brain injury.
Rest after traumatic brain injury (TBI) has been a part of clinical practice for more than a century but the use of rest as a treatment has ancient roots. In contemporary practice, rest recommendations have been significantly reduced but are still present. This advice to brain injured patients, on the face of it makes some logical sense but was not historically anchored in either theory or empirical data. ⋯ The goals and theoretical explanations for this approach have evolved and in modern conception include avoiding reinjury and reducing the metabolic demands on injured tissue. Moreover, as cellular and molecular understanding of the physiology of TBI developed, scientists and clinicians sometimes retroactively cited these new data in support of rest recommendations. Here, we trace the history of this approach and how it has been shaped by new understanding of the underlying pathology associated with brain injury.

ReviewPrediction Models for Neurocognitive Outcome of Mild Traumatic Brain Injury in Children: a Systematic Review.
Mild traumatic brain injury (mTBI) is highly prevalent in children. Recent literature suggests that children with mTBI are at considerable risk of persisting neurocognitive deficits, threatening post-injury child development. Nevertheless, clinical tools for early identification of children at risk are currently not available. ⋯ The findings indicate that demographic factors, pre-morbid factors as well as acute and subacute clinical factors have relevance for neurocognitive outcome. Based on the available evidence, evaluation of demographic and pre-morbid risk factors in conjunction with a subacute neurocognitive screening may have the best potential to predict neurocognitive outcome in children with mTBI. The findings underline the importance of future research contributing to early identification of children at risk of persisting neurocognitive deficits.
