Observational StudyAssociations between peer relationships and self-esteem after childhood traumatic brain injury: exploring the mediating role of loneliness.
Pediatric traumatic brain injury (TBI) can impact psycho-social functioning, including friendships and experiences of loneliness; however, few studies have explored associations between these factors and self-esteem. To address this gap, the objective of this study was to document inter-relationships between friendship quality, peer-related loneliness, and self-esteem 12 months post-injury. The sample in this prospective, longitudinal observational study consisted of 135 children, including 92 children with TBI (57 mild, 35 moderate-severe TBI) and 43 typically developing control (TDC) children. ⋯ In mediation models, poorer quality friendships were associated with greater peer-related loneliness, and greater peer-related loneliness was related to reduced athletic and social self-esteem, at 12 months post-TBI. Loneliness with peers mediated the effects of both friendship support and friendship satisfaction on children's social self-esteem. Our preliminary findings suggest that regular monitoring of social interactions post-TBI might facilitate early identification of children who are likely to benefit from interventions targeting peer-related loneliness, which in turn may lower risk for poorer self-esteem.

Review Meta AnalysisCognitive outcome following complicated mild Traumatic Brain Injury: A literature review and meta-analysis.
Cognitive outcome for mild traumatic brain injury (mTBI) with positive brain imaging (complicated mTBI) was compared with that for mTBI with normal imaging (uncomplicated mTBI) and with moderate to severe TBI, using meta-analysis. Twenty-three studies utilizing objective neurocognitive tests were included in the analysis. At less than 3 months post-injury, complicated mTBI was associated with poorer cognitive outcomes than uncomplicated mTBI, but deficits were not comparable to those with moderate-severe TBI. ⋯ The extent of cognitive deficit in complicated mTBI was small and unlikely to cause significant disability. However, patients with complicated mTBI constitute a broad category encompassing individuals who may differ markedly in the nature and extent of intracranial imaging abnormality, and further studies are warranted. Limitations of the available studies include small, selected samples; variations in TBI severity classification; absence of validity ("effort") testing; differing imaging methodology; and lack of long-term follow-up.

Long-term risk of cardiovascular disease after traumatic brain injury: screening and prevention.
Traumatic brain injury (TBI) is highly prevalent among individuals participating in contact sports, military personnel, and in the general population. Although it is well known that brain injury can cause neurological and psychiatric complications, evidence from studies on individuals exposed to a single or repetitive brain injuries suggests an understudied association between TBI and the risk of developing chronic cardiovascular diseases and risk factors for cardiovascular disease. ⋯ Similar observations made in military and professional American-style football cohorts suggest causal pathways through which modifiable cardiovascular risk factors might mediate the relationship between brain injury and chronic neurological diseases. A better understanding of cardiovascular disease risk after TBI combined with a proactive, targeted screening programme might mitigate long-term morbidity and mortality in individuals with TBI, and improve their quality of life.
