Review Meta AnalysisVery early versus delayed mobilisation after stroke.
Very early mobilisation (VEM) is performed in some stroke units and recommended in some acute stroke clinical guidelines. However, it is unclear whether very early mobilisation independently improves outcome after stroke. ⋯ VEM, which usually involved first mobilisation within 24 hours of stroke onset, did not increase the number of people who survived or made a good recovery after their stroke. VEM may have reduced the length of stay in hospital by about one day, but this was based on low-quality evidence. Based on the potential hazards reported in the single largest RCT, the sensitivity analysis of trials commencing mobilisation within 24 hours, and the NMA, there was concern that VEM commencing within 24 hours may carry an increased risk, at least in some people with stroke. Given the uncertainty around these effect estimates, more detailed research is still required.

Meta AnalysisEpidermal growth factor receptor blockers for the treatment of ovarian cancer.
This is an update of a previously published version of the review (Issue 10, 2011).Epithelial ovarian cancer (EOC) is the seventh most common cause of cancer death among women worldwide. Treatment consists of a combination of surgical debulking and platinum-based chemotherapy. Between 55% and 75% of women who respond to first-line therapy experience relapse within two years. Second-line chemotherapy is palliative and aims to reduce symptoms and prolong survival. Improved understanding about the molecular basis of EOC has led to the development of novel agents, such as epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors and anti-EGFR antibodies. ⋯ Current evidence suggests that an anti-EGFR single-agent biological treatment (EGFR TKI or anti-EGFR antibody) makes little or no difference to survival, either as maintenance treatment after first-line chemotherapy or in association with chemotherapy in recurrent cancer. Anti-EGFR therapy may increase some side effects and may or may not reduce quality of life.

Meta AnalysisAnti-vascular endothelial growth factor for diabetic macular oedema: a network meta-analysis.
Diabetic macular oedema (DMO) is a common complication of diabetic retinopathy. Antiangiogenic therapy with anti-vascular endothelial growth factor (anti-VEGF) can reduce oedema, improve vision and prevent further visual loss. These drugs have replaced laser photocoagulation as the standard of care for people with DMO. ⋯ Anti-VEGF drugs are effective at improving vision in people with DMO with three to four in every 10 people likely to experience an improvement of 3 or more lines VA at one year. Aflibercept may confer some advantage over ranibizumab and bevacizumab in people with DMO at one year in visual and anatomic terms but it is unclear whether this applies to the long-term. There is a need for more evidence on the long-term (greater than two years) comparative effects of these anti-VEGF agents. Evidence from RCTs may not apply to real-world practice, where people in need of antiangiogenic treatment are often under-treated and under-monitored.We found no signals of differences in overall safety between the three antiangiogenic drugs that are currently available to treat DMO, but our estimates are imprecise for cardiovascular events and death.

Meta AnalysisMonotherapy laser photocoagulation for diabetic macular oedema.
Diabetic macular oedema (DMO) is a complication of diabetic retinopathy and one of the most common causes of visual impairment in people with diabetes. Clinically significant macular oedema (CSMO) is the most severe form of DMO. Intravitreal antiangiogenic therapy is now the standard treatment for DMO involving the centre of the macula, but laser photocoagulation is still used in milder or non-central DMO. ⋯ Laser photocoagulation reduces the chances of visual loss and increases those of partial to complete resolution of DMO compared to no intervention at one to three years. Subthreshold photocoagulation, particularly the micropulse technique, may be as effective as standard photocoagulation and RCTs are ongoing to assess whether this minimally invasive technique is preferable to treat milder or non-central cases of DMO.

Review Meta AnalysisExercise for reducing falls in people living with and beyond cancer.
Current treatment modalities for cancer have been successful in achieving improved survivorship; however, they come with a number of long-term adverse effects. Accidental falls are a common and clinically significant adverse event in people living with and beyond cancer and rates are higher than in the rest of the population. ⋯ There is a paucity of evidence for exercise training to reduce fall rates in people living with and beyond cancer. Exercise training may improve strength, flexibility and balance for people in this population, but the evidence is very low quality.
