Decompressive craniectomy practice following traumatic brain injury, in comparison with randomized trials.
High quality evidence shows decompressive craniectomy (DC) following traumatic brain injury (TBI) may improve survival but increase the number of severely disabled survivors. Contemporary international practice is unknown. We sought to describe international use of DC, and the alignment with evidence and clinical practice guidelines, by analyzing the harmonized Collaborative European NeuroTrauma Effectiveness Research in Traumatic Brain Injury (CENTER-TBI) and Australia-Europe NeuroTrauma Effectiveness Research in Traumatic Brain Injury (OzENTER-TBI) core study datasets, which include patients admitted to intensive care units (ICUs) in Europe, the United Kingdom, and Australia between 2015 and 2017. ⋯ Of patients who underwent DC, 258/320 (80.6%) were ineligible for either trial: 149/320 (46.6%) underwent primary DC, 62/320 (19.4%) were outside the trials' age criteria, and 126/320 (39.4%) did not develop intracranial hypertension refractory to non-operative therapies prior to DC. Secondary DC was used infrequently in patients in whom it had been shown to increase survival with severe disability, indicating alignment between contemporaneous evidence and practice. However, most patients who underwent DC were ineligible for the key trials; whether they benefited from DC remains unknown.

Temporal and Spatial Changes in the Microbiome Following Pediatric Severe Traumatic Brain Injury.
The microbiome may be affected by trauma and critical illness. Many studies of the microbiome in critical illness are restricted to a single body site or time point and confounded by preexisting conditions. We report temporal and spatial alterations in the microbiome of previously healthy children with severe traumatic brain injury (TBI). ⋯ The microbiome of children with severe TBI is characterized by early depletion of commensal bacteria, loss of site specificity, and an enrichment of potential pathogens. Additional studies are needed to determine the impact of these changes on clinical outcomes.

In traumatic brain injury (TBI), large between-center differences in treatment and outcome for patients managed in the intensive care unit (ICU) have been shown. The aim of this study is to explore if European neurotrauma centers can be clustered, based on their treatment preference in different domains of TBI care in the ICU. ⋯ Although correlations between treatment policies within domains were found, the failure to cluster hospitals indicates that a specific treatment choice within a domain is not a proxy for other treatment choices within or outside the domain. These results imply that studying the effects of specific TBI interventions on outcome can be based on between-center variation without being substantially confounded by other treatments.

Spreading depolarizations (SDs) are associated with worse outcome following subarachnoid hemorrhage (SAH) and traumatic brain injury (TBI), but gold standard detection requires electrocorticography with a subdural strip electrode. Electroencephalography (EEG) ictal-interictal continuum abnormalities are associated with poor outcomes after TBI and with both delayed cerebral ischemia (DCI) and poor outcomes after SAH. We examined rates of SD detection in patients with SAH and TBI with intraparenchymal and subdural strip electrodes and assessed which continuous EEG (cEEG) measures were associated with intracranially quantified SDs. ⋯ Intraparenchymal recordings yielded low rates of SD, and documented SDs were not associated with ictal-interictal continuum abnormalities or other cEEG DCI predictors. Identifying scalp EEG correlates of SD may require training computational EEG analytics and use of gold standard subdural strip electrocorticography recordings.

Observational StudyEpidemiological Characteristics of Older Patients with Traumatic Brain Injury in China.
Increasing traumatic brain injury (TBI) among older adults constitutes a substantial socioeconomic burden, in step with the growing aging global population. Here, we aimed to investigate the profile of geriatric TBI in the CENTER-TBI China registry, a prospective observational study conducted in 56 centers of 22 provinces across China. Patients admitted to the hospital with a clinical diagnosis of TBI were enrolled in the study. ⋯ The overall in-hospital mortality rate was 8.24% (n = 199), and most survivors were transferred home. This study revealed that the demographic patterns and injury mechanisms are changing among elderly patients with TBI in China. More attention should be given to the high incidence of geriatric TBI to improve prevention and management strategies.
