Midline shift and mass lesions may occur with traumatic brain injury (TBI) and are associated with higher mortality and morbidity. The shape of intracranial pressure (ICP) pulse waveform reflects the state of cerebrospinal pressure-volume compensation which may be disturbed by brain injury. We aimed to investigate the link between ICP pulse shape and pathological computed tomography (CT) features. ⋯ ICP pulse shape reflects the reduction in cerebrospinal compensatory reserve related to space-occupying lesions despite comparable mean ICP and AmpICP levels. Future validation of PSI is necessary to explore its association with volume imbalance in the intracranial space and a potential complementary role to the existing monitoring strategies.

Randomized Controlled Trial
Mood, Activity Participation, and Leisure Engagement Satisfaction (MAPLES): results from a randomised controlled pilot feasibility trial for low mood in acquired brain injury.
Acquired brain injury (ABI) is linked to increased depression risk. Existing therapies for depression in ABI (e.g., cognitive behavioural therapy) have mixed efficacy. Behavioural activation (BA), an intervention that encourages engaging in positively reinforcing activities, shows promise. The primary aims were to assess feasibility, acceptability, and potential efficacy of two 8-week BA groups. ⋯ Both in-person and remote group BA were feasible and acceptable in ABI. Though both traditional and experiential BA may be effective, these may have different mechanisms.

Traumatic brain injury (TBI) is highly prevalent among active duty service members (ADSMs) and imposes a significant health burden, particularly on mental health (e.g., post-traumatic stress disorder [PTSD] and depressive symptoms). Little is known about how TBI setting characteristics impact PTSD and depressive symptom expression in service members undergoing interdisciplinary TBI care. ⋯ There was a differential impact of TBI settings, particularly between TBI sustained before military service and that from combat deployment among ADSMs enrolled in outpatient TBI programs. This may be indicative of differences in the characteristics of these environments (e.g., injury severity) or the impact of such an event during recovery from current TBIs. The large percentage of ADSMs who present with clinically-elevated mental health symptoms after treatment may suggest the need for additional resources to address mental health needs before, during, and after treatment in TBI programs.

Posttraumatic stress disorder (PTSD) is prevalent among military personnel and may arise following a wide range of traumatic exposures. Consciousness level following traumatic injury may play a role in the development of PTSD, but its effects have been primarily investigated in the context of traumatic brain injury. ⋯ Minimally impaired consciousness following traumatic injuries is associated with increased odds of PTSD. The role of patient awareness, analgesia, and sedation following an injury in developing PTSD warrants further investigation and could guide early diagnosis and preventive interventions.
