Review Meta AnalysisEfficacy and safety of tranexamic acid in acute traumatic brain injury: a systematic review and meta-analysis of randomized-controlled trials.
With the publication of a large randomized-controlled trial (RCT) suggesting that tranexamic acid (TXA) may improve head-injury-related deaths, we aimed to determine the safety and efficacy of TXA in acute traumatic brain injury (TBI). ⋯ In patients with acute TBI, TXA probably has no effect on mortality or disability. TXA may decrease hematoma expansion on subsequent imaging; however, this outcome is likely of less importance to patients. The use of TXA probably does not increase the risk of adverse events.

ReviewBeirut Ammonium Nitrate Blast: Analysis, Review, and Recommendations.
A massive chemical detonation occurred on August 4, 2020 in the Port of Beirut, Lebanon. An uncontrolled fire in an adjacent warehouse ignited ~2,750 tons of Ammonium Nitrate (AN), producing one of the most devastating blasts in recent history. The blast supersonic pressure and heat wave claimed the lives of 220 people and injured more than 6,500 instantaneously, with severe damage to the nearby dense residential and commercial areas. ⋯ It further reviews prior AN incidents and suggests actionable recommendations and strategies to optimize chemical safety measures, improve emergency preparedness, and mitigate the delayed clinical effects of blast and toxic gas exposures. These recommended actionable steps offer a starting point for government officials and policymakers to build frameworks, adopt regulations, and implement chemical safety protocols to ensure safe storage of hazardous materials as well as reorganizing healthcare system disaster preparedness to improve emergency preparedness in response to similar large-scale disasters and promote population safety. Future clinical efforts should involve detailed assessment of physical injuries sustained by blast victims, with systemic mitigation and possible treatment of late blast effects involving individuals, communities and the region at large.

ReviewNarrative review of clinical practice guidelines for treating people with moderate or severe traumatic brain injury.
Practice guidelines (CPGs) provide informed treatment recommendations from systematic reviews and assessment of the benefits and harms that are intended to optimize patient care. Review of CPGs addressing rehabilitation for people with moderate/severe traumatic brain injury (TBI), has not been fully investigated. ⋯ There are few CPGs addressing rehabilitation for people with moderate/severe TBI. More interventional trials are needed to determine treatment effectiveness. Timely and methodologically sound vetting of studies are needed to ensure CPG reliability and facilitate access to quality, effective treatment for people with moderate/severe TBI.

The Peripheral Immune System and Traumatic Brain Injury: Insight into the role of T-helper cells.
Emerging evidence suggests that immune-inflammatory processes are key elements in the physiopathological events associated with traumatic brain injury (TBI). TBI is followed by T-cell-specific immunological changes involving several subsets of T-helper cells and the cytokines they produce; these processes can have opposite effects depending on the disease course and cytokine concentrations. ⋯ These predictors may eventually serve as effective treatment targets to decrease morbidity and mortality and to improve the management of TBI patients. Here, we review the immunological response to TBI, the possible molecular mechanisms of this response, and therapeutic strategies to address it.

ReviewLOW-VALUE CLINICAL PRACTICES IN ADULT TRAUMATIC BRAIN INJURY: AN UMBRELLA REVIEW.
Despite numerous interventions and treatment options, the outcomes of traumatic brain injury (TBI) have improved little over the last 3 decades, which raises concern about the value of care in this patient population. We aimed to synthesize the evidence on 14 potentially low-value clinical practices in TBI care. Using umbrella review methodology, we identified systematic reviews evaluating the effectiveness of 14 potentially low-value practices in adults with acute TBI. ⋯ For the following practices, effect estimates were consistently close to the null: computed tomography (CT) in adults with mild TBI who are low-risk on a validated clinical decision rule; repeat CT in adults with mild TBI on anticoagulant therapy with no clinical deterioration; antibiotic prophylaxis for external ventricular drain placement; and decompressive craniectomy for refractory intracranial hypertension. We identified five clinical practices with evidence of lack of benefit or harm. However, evidence could not be considered to be strong for any clinical practice as effect measures were imprecise and heterogeneous, systematic reviews were often of low quality, and most included studies had a high risk of bias.
