Review Meta AnalysisAntiplatelet and anticoagulation for patients with prosthetic heart valves.
Patients with prosthetic heart valves are at increased risk for valve thrombosis and arterial thromboembolism. Oral anticoagulation alone, or the addition of antiplatelet drugs, has been used to minimise this risk. An important issue is the effectiveness and safety of the latter strategy. ⋯ Adding antiplatelet therapy, either dipyridamole or low-dose aspirin, to oral anticoagulation decreases the risk of systemic embolism or death among patients with prosthetic heart valves. The risk of major bleeding is increased with antiplatelet therapy. These results apply to patients with mechanical prosthetic valves or those with biological valves and indicators of high risk such as atrial fibrillation or prior thromboembolic events. The effectiveness and safety of low-dose aspirin (100 mg daily) appears to be similar to higher-dose aspirin and dipyridamole. In general, the quality of the included trials tended to be low, possibly reflecting the era when the majority of the trials were conducted (1970s and 1980s when trial methodology was less advanced).

Review Meta AnalysisPegylated liposomal doxorubicin for relapsed epithelial ovarian cancer.
Ovarian cancer is the eighth most common cancer in women and it is usually diagnosed at an advanced stage. The majority of ovarian tumours are epithelial in origin. Women with relapsed epithelial ovarian cancer (EOC) often have a reduced performance status with a limited life expectancy, therefore maintaining quality of life with effective symptom control is the main purpose of treatment. Drug treatment of relapsed disease is directed by the platinum-free interval: relapsed platinum-sensitive disease is usually re-treated with platinum-based therapy and platinum-resistant disease challenged with non-platinum drugs. However, the side-effects of chemotherapy agents may be severe and optimal treatment regimens are unclear. Pegylated liposomal doxorubicin (PLD), which contains a cytotoxic drug called doxorubicin hydrochloride is one of several treatment modalities that may be considered for single-agent treatment of relapsed EOC, or used in combination with other drugs. ⋯ In platinum-sensitive relapsed epithelial ovarian cancer, PLD/carbo is more effective than PAC/carbo and is better tolerated; PLD/carbo should therefore be considered as first-line treatment in women with platinum-sensitive relapsed EOC. PLD alone is a useful agent for platinum-resistant relapsed EOC, however it remains unclear how it compares with other single agents for this subgroup and in what order these agents should be used. There is insufficient evidence to support the use of PLD in combination with other agents in platinum-resistant relapsed EOC.

Review Meta AnalysisWeighted vaginal cones for urinary incontinence.
For a long time pelvic floor muscle training (PFMT) has been the most common form of conservative (non-surgical) treatment for stress urinary incontinence (SUI). Weighted vaginal cones can be used to help women to train their pelvic floor muscles. Cones are inserted into the vagina and the pelvic floor is contracted to prevent them from slipping out. ⋯ This review provides some evidence that weighted vaginal cones are better than no active treatment in women with SUI and may be of similar effectiveness to PFMT and electrostimulation. This conclusion must remain tentative until larger, high-quality trials, that use comparable and relevant outcomes, are completed. Cones could be offered as one treatment option, if women find them acceptable.

Review Meta AnalysisAnthracycline-containing regimens for treatment of follicular lymphoma in adults.
Anthracycline-containing regimens (ACR) are the most prevalent regimens in the management of patients with advanced follicular lymphoma (FL). However, there is no proof that they are superior to non-anthracycline-containing regimens (non-ACR). ⋯ The use of anthracyclines in patients with FL has no demonstrable benefit on overall survival, although it may have been mitigated by the more intense regimens given in the control arms of three of five trials. ACR improved disease control, as measured by PFS and RD with an increased risk for side effects, notably cardiotoxicity. The current evidence on the added value of ACR in the management of FL is limited. Further studies involving immunotherapy during induction and maintenance may change conclusion.
