Review Meta AnalysisReduced or modified dietary fat for preventing cardiovascular disease.
Reduction and modification of dietary fats have differing effects on cardiovascular risk factors (such as serum cholesterol), but their effects on important health outcomes are less clear. ⋯ The findings are suggestive of a small but potentially important reduction in cardiovascular risk on modification of dietary fat, but not reduction of total fat, in longer trials. Lifestyle advice to all those at risk of cardiovascular disease and to lower risk population groups, should continue to include permanent reduction of dietary saturated fat and partial replacement by unsaturates. The ideal type of unsaturated fat is unclear.

Review Meta AnalysisLifestyle changes in women with polycystic ovary syndrome.
Polycystic ovary syndrome (PCOS) affects 4% to 18% of reproductive-aged women and is associated with reproductive, metabolic and psychological dysfunction. Obesity worsens the presentation of PCOS and weight management (weight loss, maintenance or prevention of excess weight gain) is proposed as an initial treatment strategy, best achieved through lifestyle changes incorporating diet, exercise and behavioural interventions. ⋯ Lifestyle intervention improves body composition, hyperandrogenism (high male hormones and clinical effects) and insulin resistance in women with PCOS. There was no evidence of effect for lifestyle intervention on improving glucose tolerance or lipid profiles and no literature assessing clinical reproductive outcomes, quality of life and treatment satisfaction.

Review Meta AnalysisCommunity interventions for preventing smoking in young people.
Cigarette smoking is one of the leading causes of preventable death in the world. Decisions to smoke are often made within a broad social context and therefore community interventions using coordinated, multi-component programmes may be effective in influencing the smoking behaviour of young people. ⋯ There is some evidence to support the effectiveness of community interventions in reducing the uptake of smoking in young people, but the evidence is not strong and contains a number of methodological flaws.

ReviewImmediate versus delayed reconstruction following surgery for breast cancer.
Breast cancer is the most prevalent cancer in women and has a lifetime incidence of one in nine in the UK. Curative treatment requires surgery, and may involve adjuvant and neo-adjuvant therapy. In many women, post-mastectomy breast reconstruction is essential to restore body image and improve quality of life. Timing of reconstruction may be immediately at the time of mastectomy or delayed until after surgery. Outcomes such as psychosocial morbidity, aesthetics and complications rates may differ between the two approaches. ⋯ The current level of evidence for the effectiveness of immediate versus delayed reconstruction following surgery for breast cancer was based on a single RCT with methodological flaws and a high risk of bias, which does not allow confident decision-making about choice between these surgical options. Until high quality evidence is available, clinicians may wish to consider the recommendations of relevant guidelines and protocols. Although the limitations and ethical constraints of conducting RCTs in this field are recognised, adequately powered controlled trials with a focus on clinical and psychological outcomes are still required. Given the paucity of RCTs in this subject, in future versions of this review we will look at study designs other than RCTs specifically good quality cohort and case-controlstudies.

ReviewWITHDRAWN: Written individualised management plans for asthma in children and adults.
Non-adherence to treatment advice is a common phenomenon in asthma and may account for a significant proportion of the morbidity. Comprehensive care that includes asthma education, a written self-management plan and regular review has been shown to improve asthma outcomes, but the contribution of these components has not been established. ⋯ The available trials are too small and the results too few and inconsistent to form any firm conclusions as to the contribution of written self management plans in the known beneficial effects of a comprehensive asthma care programme.
