ReviewThe effectiveness of sexual health interventions for people with severe mental illness: a systematic review.
Severe mental illnesses (SMIs), such as schizophrenia and bipolar disorder, persist over time and can cause extensive disability leading to impairments in social and occupational functioning. People with SMI have higher morbidity and mortality due to physical illness than the general population and may be more likely to engage in high-risk sexual behaviour (e.g. unprotected intercourse, having multiple partners, involvement in the sex trade and illicit drug use), putting them at risk of poorer sexual health outcomes including sexually transmitted infections. Sexual health promotion interventions, developed and implemented for people with SMI, may improve participants' knowledge, attitudes, beliefs or behavioural practices and could lead to a reduction in risky sexual behaviour. ⋯ The National Institute for Health Research Health Technology Assessment Programme.

ReviewThe clinical effectiveness and cost-effectiveness of ablative therapies in the management of liver metastases: systematic review and economic evaluation.
Many deaths from cancer are caused by metastatic burden. Prognosis and survival rates vary, but survival beyond 5 years of patients with untreated metastatic disease in the liver is rare. Treatment for liver metastases has largely been surgical resection, but this is feasible in only approximately 20-30% of people. Non-surgical alternatives to treat some liver metastases can include various forms of ablative therapies and other targeted treatments. ⋯ Funding for this study was provided by the Health Technology Assessment programme of the National Institute for Health Research.

Randomized Controlled Trial Pragmatic Clinical TrialPRImary care Streptococcal Management (PRISM) study: in vitro study, diagnostic cohorts and a pragmatic adaptive randomised controlled trial with nested qualitative study and cost-effectiveness study.
Antibiotics are still prescribed to most patients attending primary care with acute sore throat, despite evidence that there is modest benefit overall from antibiotics. Targeting antibiotics using either clinical scoring methods or rapid antigen detection tests (RADTs) could help. However, there is debate about which groups of streptococci are important (particularly Lancefield groups C and G), and uncertainty about the variables that most clearly predict the presence of streptococci. ⋯ Targeting antibiotics using a clinical score (FeverPAIN) efficiently improves symptoms and reduces antibiotic use. RADTs used in combination with FeverPAIN provide no clear advantages over FeverPAIN alone, and RADTs are unlikely to be incorporated into practice until health professionals' concerns are met and they have experience of using them. Clinical scores also face barriers related to clinicians' perceptions of their utility in the face of experience. This study has demonstrated the limitation of using one data set to develop a clinical score. FeverPAIN, derived from two data sets, appears to be valid and its use improves outcomes, but diagnostic studies to confirm the validity of FeverPAIN in other data sets and settings are needed. Experienced clinicians need to identify barriers to the use of clinical scoring methods. Implementation studies that address perceived barriers in the use of FeverPAIN are needed.

Randomized Controlled TrialA pilot randomised trial to assess the methods and procedures for evaluating the clinical effectiveness and cost-effectiveness of Exercise Assisted Reduction then Stop (EARS) among disadvantaged smokers.
There have been few rigorous studies on the effects of behavioural support for helping smokers to reduce who do not immediately wish to quit. While reduction may not have the health benefits of quitting, it may lead smokers to want to quit. Physical activity (PA) helps to reduce cravings and withdrawal symptoms, and also reduces weight gain after quitting, but smokers may be less inclined to exercise. There is scope to develop and determine the effectiveness of interventions to support smoking reduction and increase physical activity, for those not ready to quit. ⋯ The study provided valuable information on the resources needed to improve study recruitment and retention. Offering support for smoking reduction and PA appears to have value in promoting reduction and cessation in disadvantaged smokers not currently motivated to quit. A large RCT is needed to assess the clinical effectiveness and cost-effectiveness of the intervention in this population.

Randomized Controlled Trial Multicenter StudyThe feasibility of using a parenting programme for the prevention of unintentional home injuries in the under-fives: a cluster randomised controlled trial.
Unintentional injury is the leading cause of preventable death of children over the age of 1 year in the UK and a major cause of attendance at emergency departments. Children having one injury are at increased risk of further injuries. Parenting programmes can reduce injuries in preschool children if delivered in the home and on a one-to-one basis. It is not known if group-based programmes delivered outside the home are effective. ⋯ This feasibility study has developed an innovative injury prevention intervention and a tool to record parent-reported injuries in preschool children. It was not feasible to recruit parents of children who had sustained a recent injury, or to ask health visitor teams to identify potential participants and to deliver the programme. A trial should target all families attending children's centres in disadvantaged areas. The intervention could be delivered by a health professional supported by a member of the children's centre team in a community setting.
