Comparative StudyCoping strategies as a predictor of post-concussive symptoms in children with mild traumatic brain injury versus mild orthopedic injury.
This study examined whether children's coping strategies are related to post-concussive symptoms following mild traumatic brain injury (TBI) versus orthopedic injury (OI). Participants were 8- to 15-year-old children with mild TBI (n = 167) or OI (n = 84). They rated their current preferred coping strategies and post-injury symptoms at 2 weeks (baseline) and 1, 3, and 12 months post-injury. ⋯ Higher problem-focused disengagement predicted larger group differences in children's ratings of symptoms, suggesting that problem-focused disengagement moderates the effects of mild TBI. Coping strategies collectively accounted for approximately 10-15% of the variance in children's post-concussive symptoms over time. The findings suggest that coping may play an important role in accounting for children's perceptions of post-concussive symptoms after mild TBI.

Cognitive and functional outcome after out of hospital cardiac arrest.
The nature of residual cognitive deficits after out of hospital cardiac arrest (OHCA) is incompletely described and has never been defined against a cardiac control (CC) group. The objective of this study is to examine neuropsychological outcomes 3 months after OHCA in patients in a "middle range" of acute severity. Thirty prospective OHCA admissions with coma >1 day and responsive but confused at 1 week, and 30 non-OHCA coronary care admissions were administered standard tests in five cognitive domains. ⋯ Coma duration was associated with group. Neither group had a high prevalence of depression. For most patients within the "middle range" of acute severity of OHCA, cognitive and functional outcomes at 3 months were encouraging.

Comparative StudyDeteriorated executive functions in patients with successful surgery for pituitary adenomas compared with other chronically ill patients.
Pituitary adenomas, even after successful treatment, are associated with cognitive impairments. It is unclear whether these deficits are a consequence of unspecific factors associated with having a chronic illness and whether the cognitive dysfunctions exceed those of other chronically ill patients. Thirty-eight patients with transsphenoidal surgery for pituitary adenomas and 38 patients undergoing L-thyroxine replacement therapy after thyroid surgery were studied neuropsychologically with established tests. ⋯ Attention (p = .007), attentional speed (p = .0004), executive control (p = .04), and working memory (p = .01), were significantly reduced in patients with pituitary adenomas compared with other chronically ill patients. In contrast, no differences were found between the groups for verbal memory (all subtests: p ≥ .06). Patients with successful surgery for pituitary adenomas show also in comparison with other chronically ill patients an increased risk for deficits in certain aspects of cognitive function, including attention and working memory, supporting the relevance of the brain lesion and its treatment for these dysfunctions.
