Review Meta AnalysisAntibiotic prophylaxis for surgical introduction of intracranial ventricular shunts.
Systemic antibiotics and antibiotic-impregnated shunt systems are often used to prevent shunt infection. ⋯ We could demonstrate a benefit of systemic prophylactic antibiotics for the first 24 hours postoperatively to prevent shunt infection, regardless of the patient's age and the type of internal shunt used. The benefit of its use after this period remains uncertain. However this data derives from the rate of shunt infection, which is an intermediary outcome. Future trials should evaluate the effectiveness of different regimens of systemic antibiotics rather than placebo, and should include all-cause mortality, shunt revision and adverse events as additional outcomes. Evidence suggests that antibiotic-impregnated catheters reduce the incidence of shunt infection although more well-designed clinical trials testing the effect of antibiotic-impregnated shunts are required to confirm their net benefit.

ReviewMethods of consumer involvement in developing healthcare policy and research, clinical practice guidelines and patient information material.
The importance of consumer involvement in health care is widely recognised. Consumers can be involved in developing healthcare policy and research, clinical practice guidelines and patient information material, through consultations to elicit their views or through collaborative processes. Consultations can be single events, or repeated events, large or small scale. They can involve individuals or groups of consumers to allow debate; the groups may be convened especially for the consultation or be established consumer organisations. They can be organised in different forums and through different media. We anticipated finding few comparative evaluations that reliably evaluated the effects of consumer involvement. ⋯ There is little evidence from comparative studies of the effects of consumer involvement in healthcare decisions at the population level. The studies included in this review demonstrate that randomised controlled trials are feasible for providing evidence about the effects of consulting consumers to inform these decisions.

Malignant pleural mesothelioma is a relatively uncommon disease, but the incidence is increasing and is expected to peak in many developed countries in the next two decades. The management of patients with malignant mesothelioma is controversial. Very few patients are suitable for any potentially curative treatment and the effectiveness of radical therapy with surgery, radiotherapy and/or chemotherapy in curing patients or prolonging survival is uncertain. The role of radiotherapy is controversial although it has been used as part of multimodal therapy. The present review will try to clarify these uncertainties. ⋯ As radiotherapy has never been compared to chemotherapy or surgery or to best supportive care (as part of combination therapy) in a prospective, randomised trial, no data exist supporting one or the other treatment as a better option for patients with malignant pleural mesothelioma. There is a need for multicentre controlled randomised trials assessing the role of radiotherapy in the radical treatment of malignant pleural mesothelioma. The studies should be limited to patients with malignant pleural mesothelioma, classified by stage, cytology and type of radiotherapy. The type of radiotherapy should be defined in advance and variables of radiotherapy dose definition and delivery should be carefully controlled.

ReviewIncreased energy intake for preterm infants with (or developing) bronchopulmonary dysplasia/ chronic lung disease.
Preterm infants with bronchopulmonary dysplasia/chronic lung disease have nutritional deficits that may contribute to short and long term morbidity and mortality. Increasing the daily energy intake for these infants may improve their respiratory, growth and neurodevelopmental outcomes. ⋯ To date, no randomized controlled trials are available that examine the effects of increased versus standard energy intake for preterm infants with (or developing) CLD/BPD. Research should be directed at evaluating the effects of various levels of energy intake on this group of infants on clinically important outcomes like mortality, respiratory status, growth and neurodevelopment. The benefits and harms of various ways of increasing energy intake, including higher energy density of milk feed and/or fluid volume (clinically realistic target volume should be set), parenteral nutrition, and the use of various constituents of energy like carbohydrate, protein and fat for this purpose also need to be assessed.

Review Meta AnalysisDouble gloving to reduce surgical cross-infection.
The invasive nature of surgery, with its increased exposure to blood, means that during surgery there is a high risk of transfer of pathogens. Pathogens can be transferred through contact between surgical patients and the surgical team, resulting in post-operative or blood borne infections in patients or blood borne infections in the surgical team. Both patients and the surgical team need to be protected from this risk. This risk can be reduced by implementing protective barriers such as wearing surgical gloves. Wearing two pairs of surgical gloves, triple gloves, glove liners or cloth outer gloves, as opposed to one pair, is considered to provide an additional barrier and further reduce the risk of contamination. ⋯ There is no direct evidence that additional glove protection worn by the surgical team reduces surgical site infections in patients, however the review has insufficient power for this outcome. The addition of a second pair of surgical gloves significantly reduces perforations to innermost gloves. Triple gloving, knitted outer gloves and glove liners also significantly reduce perforations to the innermost glove. Perforation indicator systems results in significantly more innermost glove perforations being detected during surgery.
