Review Meta AnalysisThe Renin Angiotensin System as a potential treatment target for Traumatic Brain Injury.
Traumatic brain injury (TBI) is a major health concern and leading cause of death and disability in young adults in the United Kingdom and worldwide; however, there is a paucity of disease modifying therapies for the treatment of TBI. This review investigates the potential of the renin-angiotensin system (RAS) as a treatment pathway for TBI in adults. Relevant electronic databases were searched on December 18, 2019, and updated May 16, 2021. ⋯ We conclude that angiotensin-receptor blockers, especially candesartan, show positive outcomes post-TBI in pre-clinical studies with moderate quality of evidence (Grading of Recommendations Assessment, Development and Evaluation [GRADE]). More research into the effect of regulatory-RAS targeting drugs is needed. Clinical trials of candesartan following TBI are recommended, because there is strong and consistent evidence of neuroprotection shown by these pre-clinical studies.

ReviewWhen is it safe to resume anticoagulation in traumatic brain injury?
When to resume or initiate anticoagulation therapy following traumatic brain injury (TBI) is controversial. This summary describes the latest evidence to guide best practice. ⋯ Strategies and timing to start prophylactic and TAC differ significantly between institutions and physicians. Each TBI patient should be evaluated on a case-by-case basis on when to start anticoagulation. More investigation is required to guide best practice.

The principle of optimizing oxygen delivery to the injured brain rests on the premise that both hypoxia and hyperoxia are important mediators of secondary brain injury and should be avoided. This rationale has prompted a move towards incorporating oxygenation endpoints into the management of neurocritical care patients, particularly those with traumatic brain injury. The present review will seek to describe clinical strategies to optimize oxygenation in the acutely brain-injured patient, drawing upon relevant physiologic principles and clinical data, where it exists. ⋯ Although there is growing interest in the use of brain tissue oxygenation as a resuscitative endpoint, many of these therapies are based on physiologic principles with little robust clinical evidence to guide their application. Clinicians must be mindful of this and balance the putative benefits of improving oxygenation against the risks associated with the use of such therapies.

ReviewA Framework to Advance Biomarker Development in the Diagnosis, Outcome Prediction, and Treatment of Traumatic Brain Injury.
Multi-modal biomarkers (e.g., imaging, blood-based, physiological) of unique traumatic brain injury (TBI) endophenotypes are necessary to guide the development of personalized and targeted therapies for TBI. Optimal biomarkers will be specific, sensitive, rapidly and easily accessed, minimally invasive, cost effective, and bidirectionally translatable for clinical and research use. For both uses, understanding how TBI biomarkers change over time is critical to reliably identify appropriate time windows for an intervention as the injury evolves. ⋯ Prognostic biomarkers that reliably predict outcomes and recovery windows to assess neurodegenerative change and guide decisions for return to play or duty are also important. TBI biomarkers that fill these needs will transform clinical practice and could reduce the patient's risk for long-term symptoms and lasting deficits. This article summarizes biomarkers currently under investigation and outlines necessary steps to achieve short- and long-term goals, including how biomarkers can advance TBI treatment and improve care for patients with TBI.

ReviewAcute traumatic brain injury in frail patients: the next pandemic.
To highlight recent findings on the evaluation and impact of frailty in the management of patients with traumatic brain injury (TBI). ⋯ The current review highlights the crucial importance of frailty evaluation in TBI, also given the changing epidemiology of this condition. To ensure adequate assessment, prevention and management, both in and outside hospital, there is an urgent need for a valid screening tool and a specific frailty-based and comorbidity-based clinical approach.
