After severe head injury, many children continue to experience major cognitive and behavioural problems and consequent educational difficulties, even after good physical recovery. Forty three children referred to the regional multidisciplinary head injury rehabilitation team are described. The clinical outcome at a median interval of 13 months after injury showed that 18 (42%) had persistent neurological impairment and 15 (35%) had an identified need for special educational support. Thirty seven children were further assessed for psychiatric morbidity, cognitive impairment, and classroom performance. Rutter behavioural questionnaires were sent to parents and teachers of head injured index cases and classmate controls matched for age and sex. Index parents scored their children significantly worse in both 'health' and 'habits' and more cases than controls had scores suggesting a psychiatric disorder. Teachers scored index cases significantly worse for five of the traits questioned, but discriminated cases from controls less decisively than parents. Index cases were significantly disadvantaged on teachers' assessments of classroom skills and performance. A need for improved support and training of staff who teach head injured children was identified.

Curcumin is a polyphenol present in turmeric and is credited with anti-inflammatory, antioxidant, and chemoprotective properties. Questions remain surrounding curcumin's bioavailability and the mechanism by which it may exert neuroprotective effects. Following PRISMA 2009 guidelines, a systematic review was conducted to identify randomized, placebo-controlled trials investigating the effects of curcumin supplementation on cognitive function in older adults (>50 years). Five databases were searched (CINAHL, Cochrane Library, PubMed, SCOPUS, Web of Science) with five studies identified, each using different forms of curcumin and validated cognitive screening measures, meeting inclusion criteria. Curcumin doses ranged from between 90 and 4,000 mg/day, with significant improvements found in three of the five studies. Firstly, the most recent study found improvements with 90 mg of curcumin twice daily in tests of selective reminding (p = 0.002), visual memory (p = 0.01), and attention (p < 0.0001) over 18 months in non-demented individuals. The second study found improvement in Montreal Cognitive Assessment tool with 1,500 mg/day curcumin over 52 weeks (p = 0.02). Another study found improvement in serial three subtraction task responses after 4 weeks compared with the placebo group (p = 0.044). Of the adverse events reported (n = 58), gastrointestinal symptoms were most common (n = 34). Before curcumin can be recommended to treat or reduce rates of cognitive decline, well-designed trials with standardization in dose, method of assessing cognition, and duration, are required to determine the most bioavailable form of curcumin with minimal adverse effects.

Lack of reporting consistency is common in randomized controlled trials (RCTs) in critical care nutrition. This impacts synthesis and interpretation and may misinform clinical practice. The objective was to evaluate reporting of parallel‐group RCTs of enteral or parenteral nutrition interventions in critically ill adults against the recommendations in the Consolidated Standards of Reporting Trials (CONSORT) 2010 guidelines and a priori–defined nutrition criteria. A systematic search of CENTRAL, MEDLINE, EMBASE, and CINAHL was conducted to identify RCTs published from January 2011 to February 14, 2020. The primary outcome was the percentage of CONSORT criteria “completely met” (a score of 1) from all included studies (out of a total possible score of 37). Secondary outcomes included the percentage of CONSORT criteria that were “partially” or “not met” and the percentage of a priori–defined nutrition criteria that were “completely,” “partially,” or “not met” (adjusted to reflect criteria applicable to the paper). Data are presented as mean (standard deviation). Comparisons of normally distributed continuous data were made using a t‐test (P < .05). Of 18,969 articles identified, 56 studies met inclusion criteria. Of these, 60% (19%) of the eligible CONSORT criteria were “completely met,” 20% (9%) “partially met,” and 20% (15%) “not met.” For the nutrition criteria, 41% (20%) of the eligible criteria were “completely met,” 25% (14%) “partially met,” and 34% (17%) “not met.” Reporting against CONSORT guidelines was variable and often incomplete in relation to important a priori–defined nutrition variables.
