Antiplatelet therapy contributes to a higher risk of traumatic intracranial hemorrhage compared to anticoagulation therapy in ground-level falls: a single-center retrospective study.
Traumatic brain injury (TBI) is a common injury and constitutes up to 3% of emergency department (ED) visits. Current studies show that TBI is most commonly inflicted in older patients after ground-level falls. These patients often take medications affecting coagulation such as anticoagulants or antiplatelet drugs. Guidelines for ED TBI-management assume that anticoagulation therapy (ACT) confers a higher risk of traumatic intracranial hemorrhage (TICH) than antiplatelet therapy (APT). However, recent studies have challenged this. This study aimed to evaluate if oral anticoagulation and platelet inhibitors affected rate of TICH in head-trauma patients with ground-level falls. ⋯ This study adds to the growing evidence that APT-patients with ground-level falls might have as high or higher risk of TICH than ACT-patients. This is not addressed in the current guidelines which may need to be updated. We therefore recommend broad prospective studies.

Persistent coagulopathy after gunshot traumatic brain injury: the importance of INR and the SPIN score.
Penetrating ballistic brain injury (gunshot traumatic brain injury or GTBI) is associated with a high mortality. Admission Glascow Coma Scale (GCS), injury severity score and neurological findings, cardiopulmonary instability, coagulopathy and radiological finding such as bullet trajectory and mass effect are shown to predict survival after GTBI. We aimed to examine the dynamics of the observed coagulopathy and its association with outcome. ⋯ The average age of our sample was 28.5 years and a majority were male subjects (92%). Fifty-four (62%) of the patients survived to discharge. The GCS score, as well as the motor, verbal, and eye-opening sub-scores were higher in survivors (P < 0.001). As was expected, radiologic findings including the Marshall and Rotterdam Scores were also associated with survival (P < 0.001). Although the ISS and Head AIS scores were higher (P < 0.001), extracranial injuries were not more prevalent in non-survivors (P= 0.567). Non-survivors had lower platelet counts and elevated PTT and INR (P < 0.001) on admission. PTT normalized within 24 h but INR continued to increase in non-survivors. SPIN score, which includes INR, was a better predictor for mortality than Rotterdam, Marshall, and Baylor etc. CONCLUSION: Progressively increasing INR after GTBI is associated with poor outcome and may indicate consumption coagulopathy from activation of the extrinsic pathway of coagulation and metabolic derangements that are triggered and sustained by the brain injury. The SPIN score, which incorporates INR as a major survival score component, outperforms other available prediction models for predicting outcome after GTBI.

This scoping review was undertaken to synthetize and appraise the literature on the potential mechanisms of action of functional electrical stimulation therapy in combination with task-specific training (FEST + TST) in the rehabilitation following stroke, spinal cord injury, traumatic brain injury, or multiple sclerosis. ⋯ The results of this scoping review suggest that FEST + TST can result in multiple effects on different elements of the neuromuscular system, while most research studies were focused on the muscle changes after FEST + TST. Despite the efficacy of the FEST + TST in the neurorehabilitation after CNS injury or disease, the results of this review underline an important knowledge gap with regards to the actual mechanism of action of FEST + TST.

Traumatic brain injury (TBI) is a global health problem, for which there are no approved therapies. Advances in acute clinical care have improved post-TBI survival, yet many patients are left with chronic TBI-related disabilities (i.e. chronic TBI). ⋯ Cell therapies have neuroprotective and neurorestorative effects which are believed to modify the disease. In this article, we review the safety and efficacy of cell therapies in early-phase clinical studies that have shown potential to improve outcomes in acute to chronic phases of TBI.

Decompressive hemicraniectomy and cranioplasty using subcutaneously preserved autologous bone flaps versus synthetic implants: perioperative outcomes and cost analysis.
It has not been well-elucidated whether there are advantages to preserving bone flaps in abdominal subcutaneous (SQ) tissue after decompressive hemicraniectomy (DHC), compared to discarding bone flaps. The authors aimed to compare perioperative outcomes and costs for patients undergoing autologous cranioplasty (AC) after DHC with the bone flap preserved in abdominal SQ tissue, and for patients undergoing synthetic cranioplasty (SC). ⋯ Autologous bone flaps may offer a cost-effective option compared to synthetic flaps. However, when preserved in abdominal SQ tissue, they pose the risk of resorption over time as well as abdominal surgical site complications with increased reoperation rates. Further studies and methodologies such as cryopreservation of the bone flap may be beneficial to reduce costs and eliminate complications associated with abdominal SQ storage.
