Review Meta AnalysisInterventions for fatigue and weight loss in adults with advanced progressive illness.
Fatigue and unintentional weight loss are two of the commonest symptoms experienced by people with advanced progressive illness. Appropriate interventions may bring considerable improvements in function and quality of life to seriously ill people and their families, reducing physical, psychological and spiritual distress. ⋯ There is a lack of robust evidence for interventions to manage fatigue and/or unintentional weight loss in the advanced stage of progressive illnesses such as advanced cancer, heart failure, lung failure, cystic fibrosis, multiple sclerosis, motor neuron disease, Parkinson's disease, dementia and AIDS. The evidence contained within this overview provides some insight into interventions which may prove of benefit within this population such as exercise, some pharmacological treatments and support for self management.Researchers could improve the methodological quality of future studies by blinding of outcome assessors. Adopting uniform reporting mechanisms for fatigue and weight loss outcome measures would also allow the opportunity for meta-analysis of small studies.Researchers could also improve the applicability of recommendations for interventions to manage fatigue and unintentional weight loss in advanced progressive illness by including subgroup analysis of this population within systematic reviews of applicable interventions.More research is required to ascertain the best interventions to manage fatigue and/or weight loss in advanced illness. There is a need for standardised reporting of these symptoms and agreement amongst researchers of the minimum duration of studies and minimum percentage change in symptom experience that proves the benefits of an intervention. There are, however, challenges in providing meaningful outcome measurements against a background of deteriorating health through disease progression. Interventions to manage these symptoms must also be mindful of the impact on quality of life and should be focused on patient-orientated rather than purely disease-orientated experiences for patients. Systematic reviews and primary intervention studies should include the impact of the interventions on standardised validated quality of life measures.

Review Meta AnalysisPre-operative biliary drainage for obstructive jaundice.
Patients with obstructive jaundice have various pathophysiological changes that affect the liver, kidney, heart, and the immune system. There is considerable controversy as to whether temporary relief of biliary obstruction prior to major definitive surgery (pre-operative biliary drainage) is of any benefit to the patient. ⋯ There is currently not sufficient evidence to support or refute routine pre-operative biliary drainage for patients with obstructive jaundice. Pre-operative biliary drainage may increase the rate of serious adverse events. So, the safety of routine pre-operative biliary drainage has not been established. Pre-operative biliary drainage should not be used in patients undergoing surgery for obstructive jaundice outside randomised clinical trials.

Review Meta AnalysisSkin preparation for preventing infection following caesarean section.
The risk of maternal mortality and morbidity (particularly postoperative infection) is higher for caesarean section than for vaginal birth. With the increase in caesarean section, it is important that the risks to the mother are minimised as far as possible. This review focuses on different forms and methods for preoperative skin preparation to prevent infection. ⋯ Little evidence is available from the included randomised controlled trials to evaluate different agent forms, concentrations and methods of skin preparation for preventing infection following caesarean section. Therefore, it is not yet clear what sort of skin preparation may be most efficient for preventing postcaesarean wound and surgical site infection. There is a need for high-quality, properly designed randomised controlled trials with larger sample sizes in this field. High priority questions include comparing types of antiseptic (especially iodine versus chlorhexidine), the timing and duration of applying the antiseptic (especially previous night versus day of surgery, and application methods (scrubbing, swabbing and draping).

Review Meta AnalysisVitamin K antagonists or low-molecular-weight heparin for the long term treatment of symptomatic venous thromboembolism.
People with venous thromboembolism (VTE) are generally treated for five days with intravenous unfractionated heparin or subcutaneous low-molecular-weight heparin (LMWH) followed by three months of vitamin K antagonist treatment. Treatment with vitamin K antagonists requires regular laboratory measurements and some patients have contraindications to treatment. This is an update of a review first published in 2000 and updated in 2002. ⋯ LMWHs are possibly as effective as vitamin K antagonists in preventing symptomatic VTE after an episode of symptomatic deep venous thrombosis, but are much more expensive. Treatment with LMWH is significantly safer than treatment with vitamin K antagonists. LMWH may result in fewer episodes of bleeding and is possibly a safe alternative in some patients, especially those in geographically inaccessible areas, are reluctant to visit the thrombosis service regularly, or with contraindications to vitamin K antagonists. However, treatment with vitamin K antagonists remains the treatment of choice for the majority of patients.

Review Meta AnalysisSingle dose oral etoricoxib for acute postoperative pain in adults.
Etoricoxib is a selective cyclo-oxygenase-2 (COX-2) inhibitor licensed for the relief of chronic pain in osteoarthritis and rheumatoid arthritis, and acute pain in some jurisdictions. This class of drugs is believed to be associated with fewer upper gastrointestinal adverse effects than conventional non-steroidal anti-inflammatory drugs (NSAIDs). One additional study in acute postoperative pain has been published since the original review was completed in Issue 2, 2009. ⋯ The additional study did not change the results from the first review published in 2009, but does make the result more robust. Single dose oral etoricoxib produces high levels of good quality pain relief after surgery and adverse events did not differ from placebo. The 120 mg dose is as effective as, or better than, other commonly used analgesics.
