Review Meta AnalysisInterventions for replacing missing teeth: different times for loading dental implants.
To minimise the risk of implant failures after their placement, dental implants are kept load-free for 3 to 8 months to establish osseointegration (conventional loading). It would be beneficial if the healing period could be shortened without jeopardising implant success. Nowadays implants are loaded early and even immediately and it would be useful to know whether there is a difference in success rates between immediately and early loaded implants compared with conventionally loaded implants. ⋯ Overall there was no convincing evidence of a clinically important difference in prosthesis failure, implant failure, or bone loss associated with different loading times of implants. More well-designed RCTs are needed and should be reported according to the CONSORT guidelines (www.consort-statement.org/).

Review Meta AnalysisCommunication skills training for healthcare professionals working with people who have cancer.
This is an updated version of a review that was originally published in the Cochrane Database of Systematic Reviews in 2004, Issue 2. People with cancer, their families and carers have a high prevalence of psychological stress which may be minimised by effective communication and support from their attending healthcare professionals (HCPs). Research suggests communication skills do not reliably improve with experience, therefore, considerable effort is dedicated to courses that may improve communication skills for HCPs involved in cancer care. A variety of communication skills training (CST) courses have been proposed and are in practice. We conducted this review to determine whether CST works and which types of CST, if any, are the most effective. ⋯ Various CST courses appear to be effective in improving some types of HCP communication skills related to information gathering and supportive skills. We were unable to determine whether the effects of CST are sustained over time, whether consolidation sessions are necessary, and which types of CST programs are most likely to work. We found no evidence to support a beneficial effect of CST on HCP 'burnout', patients' mental or physical health, and patient satisfaction.

Review Meta AnalysisDressings for superficial and partial thickness burns.
An acute burn wound is a complex and evolving injury. Extensive burns produce systemic consequences, in addition to local tissue damage. Treatment of partial thickness burn wounds is directed towards promoting healing and a wide variety of dressings are currently available. Improvements in technology and advances in understanding of wound healing have driven the development of new dressings. Dressing selection should be based on their effects on healing, but ease of application and removal, dressing change requirements, cost and patient comfort should also be considered. ⋯ There is a paucity of high-quality evidence regarding the effect of different dressings on the healing of superficial and partial thickness burn injuries. The studies summarised in this review evaluated a variety of interventions, comparators and clinical endpoints and all were at risk of bias. It is impossible to draw firm and confident conclusions about the effectiveness of specific dressings, however silver sulphadiazine was consistently associated with poorer healing outcomes than biosynthetic, silicon-coated and silver dressings whilst hydrogel-treated burns had better healing outcomes than those treated with usual care.

Review Meta AnalysisThe role of maintenance therapy in acute promyelocytic leukemia in the first complete remission.
Acute promyelocytic leukemia (APL) is the most curable type of leukemia. A consensus exists regarding the need for administration of both induction and consolidation treatments, albeit using different approaches. However, there is conflicting evidence for the role of maintenance treatment in APL patients. ⋯ Maintenance therapy compared to observation in APL patients improved DFS but not OS. Similarly, ATRA and chemotherapy compared to ATRA improved DFS but not OS. In contrast, ATRA based regimens compared to non-ATRA based regimens did not demonstrate a survival benefit. The significance of these findings is limited due to clinical heterogeneity between studies.

Review Meta AnalysisLong-term effects of weight-reducing drugs in hypertensive patients.
All major guidelines for antihypertensive therapy recommend weight loss; anti-obesity drugs might be a helpful option. ⋯ In patients with elevated blood pressure, orlistat and sibutramine reduced body weight to a similar degree. In the same trials, orlistat reduced blood pressure and sibutramine increased blood pressure. No trials investigating rimonabant in people with elevated blood pressure could be included. Long-term trials assessing the effect of orlistat, sibutramine and rimonabant on mortality and morbidity are lacking. Rimonabant and sibutramine have been withdrawn from the market for the time being.
