Multicenter Study Observational Study
Derivation of Coagulation Phenotypes and the Association with Prognosis in Traumatic Brain Injury: A Cluster Analysis of Nationwide Multicenter Study.
The pathogenesis and pathophysiology of traumatic coagulopathy during traumatic brain injury is not well understood, and the appropriate treatment strategy for this condition has not been established. This study aimed to evaluate the coagulation phenotypes and their effect on prognosis in patients with isolated traumatic brain injury. ⋯ This multicenter, observational study identified five different coagulation phenotypes of traumatic brain injury and showed associations of these phenotypes with in-hospital mortality.

Automatic Quantification of Enlarged Perivascular Space in Patients with Traumatic Brain Injury Using Super-resolution of T2-weighted Images.
The perivascular space (PVS) is important to brain waste clearance and brain metabolic homeostasis. Enlarged PVS (ePVS) becomes visible on magnetic resonance imaging (MRI) and is best appreciated on T2-weighted (T2w) images. However, quantification of ePVS is challenging because standard-of-care T1-weighted (T1w) and T2w images are often obtained via two-dimensional (2D) acquisition, whereas accurate quantification of ePVS normally requires high-resolution volumetric three-dimensional (3D) T1w and T2w images. ⋯ We demonstrate that images produced by SR of 2D T2w images can be automatically analyzed to produce results comparable to those obtained by 3D T2 volumes. Reliable age-related ePVS burden across the whole-brain white matter was observed in all subjects. Poor sleep, affecting the glymphatic function, may contribute to the accelerated increase of ePVS burden following TBI.

Thomas Aquinas (1225-1274) was an influential medieval Christian theologian and arguably one of the greatest scholastic philosophers. He produced more than 60 works in his 48 years, including his magnum opus, the Summa Theologica. The Catholic Church regards him as a canonized saint and one of 37 Doctors of the Church. ⋯ Through an analysis of his final illness as documented in key Latin and Italian historical texts, and careful observation of the reputed skull relic in Priverno, Italy, the authors postulate that Aquinas may have suffered a traumatic brain injury and that his death at age 48 was occasioned by a chronic subdural hematoma. Examination of the skull was inconclusive; however, the historical textual analysis supports this theory. A more in-depth forensic analysis of the skull may help confirm the diagnosis.

Head Injury due to Intimate Partner Violence: Injury Characteristics, Subacute Symptoms, and Receipt of Care.
Women survivors of intimate partner violence (IPV) have increased risk of repetitive neurotrauma in their lifetime but have received less research focus compared with populations of athletes, veterans, and emergency department patients. The current study examined the importance of IPV as a contextual mechanism of injury, by comparing women survivors of IPV based on whether they experienced a head injury due to IPV or a head injury not due to IPV. The analyses involved archival data from in-person interviews conducted with women who received a protective order against an intimate partner in Kentucky from 2001 to 2004 (n = 641). ⋯ Among women survivors of IPV, those reporting IPV-related head injuries reported greater subacute symptoms, but a lower likelihood of being hospitalized or receiving rehabilitative care. Women with self-reported IPV-related head injuries represent an underserved population that is often unevaluated following injury and may have many unmet care needs. Future studies should examine persistent symptoms following IPV-related head injuries and interventions that would be most beneficial for this population.

Although blunt cerebrovascular injuries (BCVIs) are relatively common in patients with traumatic brain injuries (TBIs), uncertainty remains regarding optimal management strategies to prevent neurological complications, morbidity, and mortality. Our objectives were to characterize common care patterns; assess the prevalence of adverse outcomes, including stroke, functional deficits, and death, by BCVI grade; and evaluate therapeutic approaches to treatment in patients with BCVI and TBI. ⋯ In patients with TBI, BCVIs impart greater risk for stroke and other associated morbidities as their severity increases. It may prove difficult to mitigate high-grade BCVI-related stroke, considering most events occur in the acute window. The paucity of late time frame strokes suggest that current management strategies do help mitigate risks.
