WITHDRAWN: Antiplatelet agents versus control or anticoagulation for heart failure in sinus rhythm.
CONCLUSIONS: At present there is little evidence from long term RCTs to recommend the use of antiplatelet therapy to prevent thromboembolism in patients with heart failure in sinus rhythm. A possible interaction with ACE inhibitors may reduce the efficacy of aspirin, although this evidence is mainly from retrospective analyses of trial cohorts and two RCTs. There is also no current evidence to support the use of oral anticoagulation (when compared to aspirin/clopidogrel) in patients with heart failure in sinus rhythm. Anticoagulation/antiplatelet therapy should be reserved for heart failure patients with other comorbiditie...

Nitrous oxide-based techniques versus nitrous oxide-free techniques for general anaesthesia.
CONCLUSIONS: Given the evidence from this Cochrane review, the avoidance of nitrous oxide may be reasonable in participants with pre-existing poor pulmonary function or at high risk of postoperative nausea and vomiting. Since there are eight studies awaiting classification, selection bias may exist in our systematic review. PMID: 26545294 [PubMed - as supplied by publisher]

Thrombolytic therapy for pulmonary embolism.
CONCLUSIONS: There is low quality evidence that thrombolytics reduce death following acute pulmonary embolism compared with heparin. Furthermore, thrombolytic therapies included in the review were heterogeneous. Thrombolytic therapy may be helpful in reducing the recurrence of pulmonary emboli but may cause more major and minor haemorrhagic events and stroke. More high quality double blind RCTs assessing safety and cost-effectiveness are required. PMID: 26419832 [PubMed - as supplied by publisher]

Combined oral contraceptives: the risk of myocardial infarction and ischemic stroke.
CONCLUSIONS: This network meta-analysis showed that the risk of myocardial infarction or ischemic stroke was only increased in women using COCs containing ≥ 50 µg of estrogen. Regarding myocardial infarction or ischemic stroke, prescribing COCs with < 50 µg of estrogen seems safe. When combined with the results of studies on the risk of venous thrombosis in COC users, it seems that the COC pill containing levonorgestrel and 30 µg of estrogen is the safest oral form of hormonal contraception.

Antifibrinolytic drugs for acute traumatic injury.
CONCLUSIONS: TXA safely reduces mortality in trauma patients with bleeding without increasing the risk of adverse events.  TXA should be given as early as possible and within three hours of injury, as further analysis of the CRASH-2 trial showed that treatment later than this is unlikely to be effective and may be harmful. Although there is some promising evidence for the effect of TXA in patients with TBI, substantial uncertainty remains.Two ongoing trials being conducted in patients with isolated TBI should resolve these remaining uncertainties.

Red blood cell transfusion for people undergoing hip fracture surgery.
CONCLUSIONS: We found low quality evidence of no difference in mortality, functional recovery or postoperative morbidity between 'liberal' versus 'restrictive' thresholds for red blood cell transfusion in people undergoing surgery for hip fracture. Although further research may change the estimates of effect, the currently available evidence does not support the use of liberal red blood cell transfusion thresholds based on a 10 g/dL haemoglobin trigger in preference to more restrictive transfusion thresholds based on lower haemoglobin levels or symptoms of anaemia in these people. Future research needs to address the effec...

Anticoagulants for acute ischaemic stroke.
CONCLUSIONS: Since the last version of the review, no new relevant studies have been published and so there is no additional information to change the conclusions. Early anticoagulant therapy is not associated with net short- or long-term benefit in people with acute ischaemic stroke. Treatment with anticoagulants reduced recurrent stroke, deep vein thrombosis and pulmonary embolism, but increased bleeding risk. The data do not support the routine use of any of the currently available anticoagulants in acute ischaemic stroke. PMID: 25764172 [PubMed - as supplied by publisher]

Hormone therapy for preventing cardiovascular disease in post-menopausal women.
CONCLUSIONS: Our review findings provide strong evidence that treatment with hormone therapy in post-menopausal women overall, for either primary or secondary prevention of cardiovascular disease events has little if any benefit and causes an increase in the risk of stroke and venous thromboembolic events.

Statins for primary prevention of venous thromboembolism.
CONCLUSIONS: Available evidence showed that rosuvastatin was associated with a reduced incidence of VTE, but the evidence was limited to a single RCT and any firm conclusions and suggestions could be not drawn. Randomised controlled trials of statins (including rosuvastatin) are needed to evaluate their efficacy in the prevention of VTE. PMID: 25518837 [PubMed - as supplied by publisher]

Parenteral anticoagulation in ambulatory patients with cancer.
CONCLUSIONS: Heparin may have a small effect on mortality at 12 months and 24 months. It is associated with a reduction in venous thromboembolism and a likely increase in minor bleeding. Future research should further investigate the survival benefit of different types of anticoagulants in patients with different types and stages of cancer. The decision for a patient with cancer to start heparin therapy for survival benefit should balance the benefits and downsides, and should integrate the patient's values and preferences.

Erythropoiesis-stimulating agents for anaemia in adults with chronic kidney disease: a network meta-analysis.
CONCLUSIONS: In the CKD setting, there is currently insufficient evidence to suggest the superiority of any ESA formulation based on available safety and efficacy data. Directly comparative data for the effectiveness of different ESA formulations based on patient-centred outcomes (such as quality of life, fatigue, and functional status) are sparse and poorly reported and current research studies are unable to inform care. All proprietary ESAs (epoetin alfa, epoetin beta, darbepoetin alfa, and methoxy polyethylene glycol-epoetin beta) prevent blood transfusions but information for biosimilar ESAs is less conclusive. Compara...

Beta-blockers for preventing stroke recurrence.

Pre-hospital versus in-hospital thrombolysis for ST-elevation myocardial infarction.
CONCLUSIONS: Pre-hospital thrombolysis reduces time to treatment, based on studies conducted in higher income countries. In settings where it can be safely and correctly administered by trained staff, pre-hospital thrombolysis may be an appropriate intervention. Pre-hospital thrombolysis has the potential to reduce the burden of STEMI in lower- and middle-income countries, especially in individuals who have limited access to in-hospital thrombolysis or percutaneous coronary interventions. We found no randomised controlled trials evaluating the efficacy of pre-hospital thrombolysis for STEMI in lower- and middle-income coun...

Haemodilution for acute ischaemic stroke.
CONCLUSIONS: The overall results of this review showed no clear evidence of benefit of haemodilution therapy for acute ischaemic stroke.These results are compatible with no persuasive beneficial evidence of haemodilution therapy for acute ischaemic stroke. This therapy has not been proven to improve survival or functional outcome. PMID: 25159027 [PubMed - as supplied by publisher]
