9 to 4.4), systolic blood pressure had reduced more in the exercise group than the comparison group by 4.2 mm Hg (95% CI 1.6 to 6.9), and the coronary heart disease risk score had reduced more in the exercise group

than in the comparison group by 3.1 units (95% CI 2.0 to 4.0). Conclusion: Exercise was effective in improving glycaemic control, increasing physical activity, and improving cardiovascular risk profile in sedentary people with Type 2 diabetes mellitus, providing benefits over and above individual counselling. Obesity and lack of physical activity are major risk factors for the development of Type 2 diabetes, and exercise (along with medication and diet) has long been recognised as one of the three cornerstones of diabetic therapy (Irvine and Taylor 2009). This very large randomized controlled trial provides further high quality evidence selleck chemicals that high intensity and progressive exercise can benefit people with Type 2 diabetes. Although the reduction in HbAlc of 0.30% found in this trial may seem relatively small, any reduction in HbAlc is considered clinically significant as it is likely to reduce the risk of diabetic

complications (Stratton et al 2000). We also need to consider that the baseline HbAlc values of the participants in this trial were considered to be only slightly elevated to start with; therefore a reduction of 0.30% in the exercise group allowed participants to achieve the recommended target HbAlc value of less than 7.0% (ADA 2008). The combined intervention was replicable and feasible as it was held in community-type gyms buy AUY-922 using readily available equipment (aerobic exercise inhibitors consisted of either treadmill, step, elliptical, arm or cycle ergometer, and resistance training consisted of chest press, lateral pull-down, squat/leg press,

Thiamine-diphosphate kinase and abdominal exercises) over two sessions per week. The trial provides evidence that education alone is not adequate to cause sufficient behavioural change to reduce risk factors related to diabetes and cardiovascular disease. It is evident that adults also need a practical component to their learning in order to induce behavioural change that is adequate to obtain results. Exercise is a vital component of diabetes management and this trial is further evidence that structured, supervised exercise sessions get results. “
“Summary of: Moore RP et al (2011) A randomised trial of domiciliary, ambulatory oxygen in patients with COPD and dyspnoea but without resting hypoxaemia. Thorax 66: 32–37. [Prepared by Kylie Hill, CAP Editor.] Question: In patients with COPD and exertional dyspnoea, but without severe hypoxaemia at rest, does domiciliary ambulatory oxygen change dyspnoea, health-related quality of life, mood, or functional status? Design: Randomised controlled trial in which the investigators and participants were blinded to group allocation and the randomisation sequence was concealed prior to allocation.
