Severe Tbi

Background: Previous research addressing cognitive recovery after traumatic brain injury (TBI) in adults has predominately used cross-sectional methods. This systematic review examines longitudinal research into cognitive recovery in the first 2 years following moderate-to-severe TBI in adults and aims to identify apparent methodological issues with the existing literature.Design: Systematic review of the first 2 years post-trauma.Setting: Data were extracted from three electronic databases and manual searches of published articles until October 2012.Participants: Two hundred and forty-two participants with severe TBI and 281 comparison participants were used to calculate effect sizes.Results: Twenty papers met the selection criteria, with effect sizes computed from four studies. Moderate-to-large effect sizes were initially observed between the TBI and comparison groups on most measures (range: d = 0.2–2.8). Recovery continued in all five cognitive domains over the 2 years post-injury.Conclusions: Results demonstrated that cognitive recovery was continuous throughout the first 2 years following moderate-to-severe TBI. Findings also indicated different rates of recovery for the specific cognitive domains, highlighting the heterogeneous nature of cognitive recovery after TBI. The review highlighted several methodological issues within the limited existing literature; recommendations were developed to improve the evidence base.

The Right

Background: The right of children to have their voice heard has been accepted by researchers, and there are increasing numbers of qualitative health studies involving children. The ethical and methodological issues of including children in research have caused worldwide concerns, and many researchers have published articles sharing their own experiences. Objectives: To systematically review and synthesise experts’ opinions and experiences about ethical and methodological issues of including children in research, as well as related solution strategies. Research design: The research design was a systematic review of opinion-based evidence, based on the guidelines by Joanna Briggs Institute. Methods: A search of five computerised databases has been conducted in April 2014 and 2271 articles were found. After screening the titles, abstracts, full texts and appraising the quality, 30 articles were finally included in the review. A meta-aggregative approach was applied in the data analysis and synthesis process. Ethical considerations: Ethical approval is not needed as it is a systematic review of published literature. Results: Six themes were identified, including evaluating potential risks and benefits, gaining access, obtaining informed consent/assent, protecting confidentiality and privacy, building rapport and collecting rich data. The similarities and differences between research involving children and that involving adults were indicated. Conclusion: All potential incentives should be justified when designing the study. Further studies need to research how to evaluate individual capacity of children and how to balance protecting children’s right to participate and their interests in the research. Cultural differences related to researching children in different regions should also be studied.

AbstractCorrespondence from Yu et al. identify methodological issues with the systematic review of manual therapy for pediatric manuscript. Like any research study, limitations are important for readers to keep in consideration when reviewing study findings. The primary authors maintain full confidence in the use of the review to provide practicing clinicians with a comprehensive overview of the limited and low-quality available evidence regarding manual therapies for the pediatric patient.
