Control of blood pressure is considered essential in the management of trauma patients. In patients with head injuries, both hypotension and hypertension are associated with poor outcomes. The present study was undertaken to ascertain whether hypertension at emergency triage is associated with traumatic intracranial haemorrhage. ⋯ The presence of hypertension at emergency triage is associated with traumatic intracranial haemorrhage.

Comparative StudyManagement of non-progressive dysarthria: practice patterns of speech and language therapists in the Republic of Ireland.
Dysarthria is a commonly acquired speech disorder. Rising numbers of people surviving stroke and traumatic brain injury (TBI) mean the numbers of people with non-progressive dysarthria are likely to increase, with increased challenges for speech and language therapists (SLTs), service providers and key stakeholders. The evidence base for assessment and intervention approaches with this population remains limited with clinical guidelines relying largely on clinical experience, expert opinion and limited research. Furthermore, there is currently little evidence on the practice behaviours of SLTs available. ⋯ The use of specific treatment programmes varies amongst SLTs. A lack of resources is reported to restrict practice in both assessment and management. Ongoing research into the effectiveness of SLT interventions with adults with non-progressive dysarthria is required to guide clinical decision-making. SLTs identified further training needs which may provide direction for the development of professional training courses in the future.

Pharmacologically induced hypothermia attenuates traumatic brain injury in neonatal rats.
Neonatal brain trauma is linked to higher risks of mortality and neurological disability. The use of mild to moderate hypothermia has shown promising potential against brain injuries induced by stroke and traumatic brain injury (TBI) in various experimental models and in clinical trials. Conventional methods of physical cooling, however, are difficult to use in acute treatments and in induction of regulated hypothermia. ⋯ In addition, HPI201 prevented the up-regulation of pro-inflammatory tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β) and IL-6. In sensorimotor activity assessments, rats in the HPI201 treated group exhibited improved functional recovery after TBI versus controls. These data support that PIH therapy using our NTR agonist is effective in reducing neuronal and BBB damage, attenuating inflammatory response and detrimental cellular signaling, and promoting functional recovery after TBI in the developing brain, supporting its potential for further evaluation towards clinical development.

Traumatic brain injury (TBI) most frequently occurs in pediatric patients and remains a leading cause of childhood death and disability. Mild TBI (mTBI) accounts for nearly 75% of all TBI cases, yet its neuropathophysiology is still poorly understood. While even a single mTBI injury can lead to persistent deficits, repeat injuries increase the severity and duration of both acute symptoms and long-term deficits. ⋯ Examination of intrinsic and synaptic properties of layer II/III pyramidal neurons revealed no significant difference between sham-injured and rmTBI animals at rest or under convulsant challenge with the potassium channel blocker 4-aminopyridine. Overall, our findings indicate that the neuropathological changes reported after pediatric rmTBI can be effectively modeled by repeat weight drop in juvenile animals. Developing a better understanding of how rmTBI alters the pediatric brain may help improve patient care and direct "return to game" decision making in adolescents.

Limited data exist on the role of adjunctive intraventricular (IVT) antibiotics for the treatment of central nervous system (CNS) infections in traumatic brain injury (TBI) patients. ⋯ TBI patients with CNS infections had similar microbiological and clinical cure rates whether they were treated with adjunctive IVT antibiotics or IV antibiotics alone. Shorter than recommended durations of antibiotic therapy still resulted in acceptable cure rates and similar clinically relevant outcomes.
