ReviewA systematic review of outcome measures used in forensic mental health research with consensus panel opinion.
To describe and assess outcome measures in forensic mental health research, through a structured review and a consensus panel. ⋯ A wide range of domains are relevant to assessing outcomes of interventions in forensic mental health services. Evaluations need to take account of public safety, but also clinical, rehabilitation and humanitarian outcomes. Recidivism is a very high priority; the public expects interventions that will reduce future criminal behaviour. Greater attention needs to be given to validity of measurement, given the enormous variety of approaches to measurement. More research is needed on methods to take account of the heterogeneity of seriousness of forms of recidivism in outcome measurement. Validity of self-report instruments regarding recidivism also needs examination by further research. Mental health is clearly also an important dimension of outcome. The review provides clear support for the view that domains such as quality of life, social function and psychosocial adjustment have not been extensively employed in forensic mental health research, but are relevant and important issues. The role of such instruments needs more consideration.

ReviewThe clinical effectiveness and cost-effectiveness of topotecan for small cell lung cancer: a systematic review and economic evaluation.
To assess the clinical effectiveness and cost-effectiveness of topotecan as second-line treatment for small cell lung cancer (SCLC). ⋯ Topotecan appeared to be better than BSC alone in terms of improved survival, and was as effective as CAV and less favourable than i.v. amrubicin in terms of response. Oral topotecan and i.v. topotecan were similar in efficacy. Topotecan offers additional benefit over BSC, but at increased cost. ICERs for i.v. topotecan, compared with BSC, were high and suggest that it is unlikely to be a cost-effective option. The ICER for oral topotecan is at the upper extreme of the range conventionally regarded as cost-effective from an NHS decision-making perspective. Further research into the QoL of patients with relapsed SCLC could identify the impacts of disease progression and treatment response.

ReviewSelf-monitoring of blood glucose in type 2 diabetes: systematic review.
To examine whether or not self-monitoring of blood glucose (SMBG) is worthwhile, in terms of glycaemic control, hypoglycaemia, quality of life (QoL) and cost per quality-adjusted life-year (QALY), in people with type 2 diabetes (T2DM) who were not treated with insulin or who were on basal insulin in combination with oral agents. ⋯ The evidence suggested that SMBG is of limited clinical effectiveness in improving glycaemic control in people with T2DM on oral agents, or diet alone, and is therefore unlikely to be cost-effective. SMBG may lead to improved glycaemic control only in the context of appropriate education - both for patients and health-care professionals - on how to respond to the data, in terms of lifestyle and treatment adjustment. Also, SMBG may be more effective if patients are able to self-adjust drug treatment. Further research is required on the type of education and feedback that are most helpful, characteristics of patients benefiting most from SMBG, optimal timing and frequency of SMBG, and the circumstances under which SMBG causes anxiety and/or depression.

Randomized Controlled TrialNorth of England and Scotland Study of Tonsillectomy and Adeno-tonsillectomy in Children(NESSTAC): a pragmatic randomised controlled trial with a parallel non-randomised preference study.
To examine the clinical effectiveness and cost-effectiveness of tonsillectomy/adeno-tonsillectomy in children aged 4-15 years with recurrent sore throats in comparison with standard non-surgical management. ⋯ Children and parents exhibited strong preferences for the surgical management of recurrent sore throats. The health of all children with recurrent sore throat improves over time, but trial participants randomised to surgical management tended to experience better outcomes than those randomised to medical management. The limitations of the study due to poor response at follow-up support the continuing careful use of 'watchful waiting' and medical management in both primary and secondary care in line with current clinical guidelines until clear-cut evidence of clinical effectiveness and cost-effectiveness is available.

ReviewDissemination and publication of research findings: an updated review of related biases.
To identify and appraise empirical studies on publication and related biases published since 1998; to assess methods to deal with publication and related biases; and to examine, in a random sample of published systematic reviews, measures taken to prevent, reduce and detect dissemination bias. ⋯ Dissemination of research findings is likely to be a biased process, although the actual impact of such bias depends on specific circumstances. The prospective registration of clinical trials and the endorsement of reporting guidelines may reduce research dissemination bias in clinical research. In systematic reviews, measures can be taken to minimise the impact of dissemination bias by systematically searching for and including relevant studies that are difficult to access. Statistical methods can be useful for sensitivity analyses. Further research is needed to develop methods for qualitatively assessing the risk of publication bias in systematic reviews, and to evaluate the effect of prospective registration of studies, open access policy and improved publication guidelines.
