Objective To examine the effects of short-term, medium-term and long-term resistance exercise training (RET) on measures of cardiometabolic health in adults. Design Intervention systematic review. Data sources MEDLINE and Cochrane Library databases were searched from inception to February 2018. The search strategy included the following keywords: resistance exercise, strength training and randomised controlled trial. Eligibility criteria for selecting studies Randomised controlled trials published in English comparing RET≥2 weeks in duration with a non-exercising control or usual care group. Participants were non-athletic and aged ≥18 years. Results A total of 173 trials were included. Medium-term and long-term RET reduced systolic blood pressure (−4.02 (95% CI −5.92 to −2.11) mm Hg, p<0.0001 and −5.08 (−10.04 to –0.13) mm Hg, p=0.04, respectively) and diastolic blood pressure (−1.73 (−2.88 to –0.57) mm Hg, p=0.003 and −4.93 (−8.58 to –1.28) mm Hg, p=0.008, respectively) versus control. Medium-term RET elicited reductions in fasted insulin and insulin resistance (−0.59 (−0.97 to –0.21) µU/mL, p=0.002 and −1.22 (−2.29 to –0.15) µU/mL, p=0.02, respectively). The effects were greater in those with elevated cardiometabolic risk or disease compared with younger healthy adults. The quality of evidence was low or very low for all outcomes. There was limited evidence of adverse events. Conclusions RET may be effective for inducing improvements in cardio metabolic health outcomes in healthy adults and those with an adverse cardio metabolic risk profile. PROSPERO registration number CRD42016037946.

Summary: Despite calls for the routine implementation of pre‐operative exercise programmes to optimise patient fitness before elective major surgery, there is no practical guidance for providing safe and effective exercise in this specific context. The following clinical guideline was developed following a review of the evidence on the effects of pre‐operative exercise interventions. We developed a series of best‐practice and, where possible, evidence‐based statements to advise on patient care with respect to exercise training in the peri‐operative period. These statements cover: patient selection for exercise training in surgical patients; integration of exercise training into multi‐modal prehabilitation programmes; and advice on exercise prescription factors and follow‐up. Although we acknowledge that further research is needed to identify the optimal exercise prescription in different clinical scenarios, we urge peri‐operative teams to make use of these recommendations.

People with severe mental ill health are more likely to smoke than those in the general population. It is therefore important that effective smoking cessation strategies are used to help people with severe mental ill health to stop smoking. This study aims to assess the effectiveness and cost –effectiveness of smoking cessation and reduction strategies in adults with severe mental ill health in both inpatient and outpatient settings. This is an update of a previous systematic review. Electronic databases were searched during September 2016 for randomised controlled trials comparing smoking cessation interventions to each other, usual care, or placebo. Data was extracted on biochemically-verified, self-reported smoking cessation (primary outcome), as well as on smoking reduction, body weight, psychiatric symptom, and adverse events (secondary outcomes). We included 26 trials of pharmacological and/or behavioural interventions. Eight trials comparing bupropion to placebo were pooled showing that bupropion improved quit rates significantly in the medium and long term but not the short term (short term RR = 6.42 95% CI 0.82–50.07; medium term RR = 2.93 95% CI 1.61–5.34; long term RR = 3.04 95% CI 1.10–8.42). Five trials comparing varenicline to placebo showed that that the addition of varenicline improved quit rates significantly in the medium term (RR = 4.13 95% CI 1.36–12.53). The results from five trials of specialised smoking cessation programmes were pooled and showed no evidence of benefit in the medium (RR = 1.32 95% CI 0.85–2.06) or long term (RR = 1.33 95% CI 0.85–2.08). There was insufficient data to allowing pooling for all time points for varenicline and trials of specialist smoking cessation programmes. Trials suggest few adverse events although safety data were not always reported. Only one pilot study reported cost effectiveness data. Bupropion and varenicline, which have been shown to be effective in the general population, also work for people with severe mental ill health and their use in patients with stable psychiatric conditions. Despite good evidence for the effectiveness of smoking cessation interventions for people with severe mental ill health, the percentage of people with severe mental ill health who smoke remains higher than that for the general population.
