Review Meta AnalysisDecision aids for people facing health treatment or screening decisions.
Decision aids are intended to help people participate in decisions that involve weighing the benefits and harms of treatment options often with scientific uncertainty. ⋯ There is high-quality evidence that decision aids compared to usual care improve people's knowledge regarding options, and reduce their decisional conflict related to feeling uninformed and unclear about their personal values. There is moderate-quality evidence that decision aids compared to usual care stimulate people to take a more active role in decision making, and improve accurate risk perceptions when probabilities are included in decision aids, compared to not being included. There is low-quality evidence that decision aids improve congruence between the chosen option and the patient's values.New for this updated review is further evidence indicating more informed, values-based choices, and improved patient-practitioner communication. There is a variable effect of decision aids on length of consultation. Consistent with findings from the previous review, decision aids have a variable effect on choices. They reduce the number of people choosing discretionary surgery and have no apparent adverse effects on health outcomes or satisfaction. The effects on adherence with the chosen option, cost-effectiveness, use with lower literacy populations, and level of detail needed in decision aids need further evaluation. Little is known about the degree of detail that decision aids need in order to have a positive effect on attributes of the choice made, or the decision-making process.

Review Meta AnalysisTreatment of Kaposi sarcoma in children with HIV-1 infection.
Kaposi sarcoma (KS) remains the second most frequently diagnosed HIV-related malignancy (HRM) worldwide and most common HRM in sub-Saharan Africa where HIV is most prevalent and human herpesvirus 8 (HHV-8), the precipitating agent for the development of KS, is endemic. The majority of KS patients would likely benefit from systemic chemotherapy in addition to the initiation of antiretroviral therapy (ART). However, as paediatric staging and treatment criteria are not readily available, there are no uniform treatment criteria. ⋯ Data describing the efficacy of different treatment options for pediatric KS, to include chemotherapy and ART, are sparse. However, the use of ART together with a chemotherapy regimen may be superior to the use of ART alone or of chemotherapy alone.

ReviewNeuraxial blockade for the prevention of postoperative mortality and major morbidity: an overview of Cochrane systematic reviews.
Various beneficial effects derived from neuraxial blocks have been reported. However, it is unclear whether these effects have an influence on perioperative mortality and major pulmonary/cardiovascular complications. ⋯ Compared with general anaesthesia, a central neuraxial block may reduce the zero to 30-day mortality for patients undergoing surgery with intermediate to high cardiac risk (level of evidence, moderate). Further research is required.

Febrile seizures can be classified as simple or complex. Complex febrile seizures are associated with fever that lasts longer than 15 minutes, occur more than once within 24 hours and are confined to one side of the child's body. It is common in some countries for doctors to recommend an electroencephalograph (EEG) for children with complex febrile seizures. A limited evidence base is available to support the use of EEG and its timing after complex febrile seizures among children. ⋯ We found no RCTs as evidence to support or refute the use of EEG and its timing after complex febrile seizures among children. A randomised controlled trial can be planned in such a way that participants are randomly assigned to the EEG group and to the non-EEG group with sufficient sample size.

ReviewAnaesthetic regimens for day-procedure laparoscopic cholecystectomy.
Day surgery involves admission of selected patients to hospital for a planned surgical procedure with the patients returning home on the same day. An anaesthetic regimen usually involves a combination of an anxiolytic, an induction agent, a maintenance agent, a method of maintaining the airway (laryngeal mask versus endotracheal intubation), and a muscle relaxant. The effect of anaesthesia may continue after the completion of surgery and can delay discharge. Various regimens of anaesthesia have been suggested for day-procedure laparoscopic cholecystectomy. ⋯ There is currently insufficient evidence to conclude that one anaesthetic regimen for day-procedure laparoscopic cholecystectomy is to be preferred over another. However, the data are sparse (that is, there were few trials under each comparison and the trials had few participants) and further well designed randomized trials at low risk of bias and which are powered to measure differences in clinically important outcomes are necessary to determine the optimal anaesthetic regimen for day-procedure laparoscopic cholecystectomy, one of the commonest procedures performed in the western world.
