Randomized Controlled Trial Multicenter StudyStudy of the use of antidepressants for depression in dementia: the HTA-SADD trial--a multicentre, randomised, double-blind, placebo-controlled trial of the clinical effectiveness and cost-effectiveness of sertraline and mirtazapine.
Depression is common in dementia, causing considerable distress and other negative impacts. Treating it is a clinical priority, but the evidence base is sparse and equivocal. This trial aimed to determine clinical effectiveness of sertraline and mirtazapine in reducing depression 13 weeks post randomisation compared with placebo. ⋯ This is a trial with negative findings but important clinical implications. The data suggest that the antidepressants tested, given with normal care, are not clinically effective (compared with placebo) for clinically significant depression in AD. This implies a need to change current practice of antidepressants being the first-line treatment of depression in AD. From the data generated we formulated the following recommendations for future work. (1) The secondary analyses presented here suggest that there would be value in carrying out a placebo-controlled trial of the clinical effectiveness and cost-effectiveness of mirtazapine in the management of Behavioural and Psychological Symptoms of Dementia. (2) A conclusion from this study is that it remains both ethical and essential for trials of new medication for depression in dementia to have a placebo arm. (3) Further research is required to evaluate the impact that treatments for depression in people with dementia can have on their carers not only in terms of any impacts on their quality of life, but also the time they spend care-giving. (4) There is a need for research into alternative biological and psychological therapies for depression in dementia. These could include evaluations of new classes of antidepressants (such as venlafaxine) or antidementia medication (e.g. cholinesterase inhibitors). (5) Research is needed to investigate the natural history of depression in dementia in the community when patients are not referred to secondary care services. (6) Further work is needed to investigate the cost modelling results in this rich data set, investigating carer burden and possible moderators to the treatment effects. (7) There is scope for reanalysis of the primary outcome in terms of carer and participant CSDD results.

ReviewDevelopment and validation of a risk model for identification of non-neutropenic, critically ill adult patients at high risk of invasive Candida infection: the Fungal Infection Risk Evaluation (FIRE) Study.
There is increasing evidence that invasive fungal disease (IFD) is more likely to occur in non-neutropenic patients in critical care units. A number of randomised controlled trials (RCTs) have evaluated antifungal prophylaxis in non-neutropenic, critically ill patients, demonstrating a reduction in the risk of proven IFD and suggesting a reduction in mortality. It is necessary to establish a method to identify and target antifungal prophylaxis at those patients at highest risk of IFD, who stand to benefit most from any antifungal prophylaxis strategy. ⋯ Funding for this study was provided by the Health Technology Assessment programme of the National Institute for Health Research.

Randomized Controlled TrialManagement of Asthma in School age Children On Therapy (MASCOT): a randomised, double-blind, placebo-controlled, parallel study of efficacy and safety.
Asthma affects one in eight children in the UK. National management guidelines have been available for many years but, unlike in adults, studies in children have been few, with their methodologies often based on inappropriate adult models. Sound medical evidence in support of the national guidelines for asthma management in children is lacking. The MASCOT study has been developed to address this need. ⋯ Based on the results of the MASCOT study it is not possible to conclude whether adding salmeterol or montelukast to ICSs can reduce the number of exacerbations requiring treatment with oral corticosteroids in children with uncontrolled asthma.

Clinical effectiveness of first-line chemoradiation for adult patients with locally advanced non-small cell lung cancer: a systematic review.
The National Institute for Health and Clinical Excellence has issued guidelines on the treatment of non-small cell lung cancer (NSCLC) and recommends that patients with stage IIIA-IIIB disease who are not amenable to surgery be treated with potentially curative chemoradiation (CTX-RT). This review was conducted as part of a larger systematic review of all first-line chemotherapy (CTX) and CTX-RT treatments for patients with locally advanced or metastatic NSCLC. However, it was considered that patients with potentially curable disease (e.g. stage IIIA) are different from those with advanced disease, who are suitable for palliative treatment only, and therefore the results should be reported separately. ⋯ The National Institute for Health Research Health Technology Assessment programme.
