Review Meta AnalysisInterrupted versus uninterrupted anticoagulation for cardiac rhythm management device insertion.
Guideline-recommended strategies to interrupt chronic anticoagulation with warfarin or direct oral anticoagulants (DOAC) during the perioperative period of cardiac implantable electronic device (CIED) surgery differ worldwide. There is uncertainty concerning the benefits and harms of interrupted and uninterrupted anticoagulation in patients undergoing CIED surgery. ⋯ Interrupted anticoagulation in people undergoing elective CIED surgery had similar outcomes to uninterrupted anticoagulation with either warfarin or DOAC medications. Certainty of evidence was judged to be low to very low for most of the assessed outcomes. Further RCTs are particularly needed to help identify whether IAC significantly impacts the risks of thromboembolic events and device-pocket hematoma.

Review Meta AnalysisAlendronate for the primary and secondary prevention of osteoporotic fractures in postmenopausal women.
Osteoporosis is an abnormal reduction in bone mass and bone deterioration, leading to increased fracture risk. Alendronate belongs to the bisphosphonate class of drugs, which inhibit bone resorption by interfering with the activity of osteoclasts (bone cells that break down bone tissue). This is an update of a Cochrane review first published in 2008. ⋯ This review is an update of the previous review (DOI: 10.1002/14651858.CD001155).

Review Meta AnalysisDifferences in the effectiveness of individual-level smoking cessation interventions by socioeconomic status.
People from lower socioeconomic groups are more likely to smoke and less likely to succeed in achieving abstinence, making tobacco smoking a leading driver of health inequalities. Contextual factors affecting subpopulations may moderate the efficacy of individual-level smoking cessation interventions. It is not known whether any intervention performs differently across socioeconomically-diverse populations and contexts. ⋯ Currently, there is no clear evidence to support the use of differential individual-level smoking cessation interventions for people from lower or higher SES groups, or that any one intervention would have an effect on health inequalities. This conclusion may change as further data become available. Many studies did not report sufficient data to be included in a meta-analysis, despite having tested the association of interest. Further RCTs should collect, analyse, and report quit rates by measures of SES, to inform intervention development and ensure recommended interventions do not exacerbate but help reduce health inequalities caused by smoking.

Review Meta AnalysisCaesarean myomectomy in pregnant women with uterine fibroids.
Postpartum haemorrhage, defined as a blood loss of 500 mL or more within 24 hours of birth, is the leading global cause of maternal morbidity and mortality. Uterine fibroids are non-cancerous growths that develop in or around the uterus, and affect an increasing number of women. Caesarean myomectomy is the surgical removal of fibroids during a caesarean section. Traditionally, obstetricians have avoided this procedure given the risk of uncontrollable haemorrhage. There is also the risk of longer operating time and more days in the hospital. However, there could be potential benefits in removing uterine fibroids for improved fertility, and caesarean section may provide an effective and efficient opportunity to perform this procedure. Given the link between removal of uterine fibroids and postpartum haemorrhage, it is prudent to evaluate current literature and assess the benefits and harms of caesarean myomectomy in pregnant women with uterine fibroids. ⋯ The review was registered with PROSPERO (CRD42024554215) and available from: https://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42024554215.

Review Meta AnalysisDirect factor Xa inhibitors versus low molecular weight heparins or vitamin K antagonists for prevention of venous thromboembolism in elective primary hip or knee replacement or hip fracture repair.
People undergoing major orthopaedic surgery are at increased risk of postoperative thromboembolic events. Low molecular weight heparins (LMWHs) are recommended for thromboprophylaxis in this population. New oral anticoagulants, including direct factor Xa inhibitors, are recommended as alternatives. They may have more advantages than disadvantages compared to LMWHs and vitamin K antagonists (VKAs, another type of anticoagulant). ⋯ Oral direct factor Xa inhibitors may have little to no effect on all-cause mortality, but the evidence is very uncertain. Oral direct factor Xa inhibitors may slightly reduce symptomatic VTE events when compared with LMWH. They may make little or no difference to major VTE events, but the evidence is very uncertain. In the evaluation of major bleeding, the evidence suggests rivaroxaban results in a slight increase in major bleeding events compared to LMWHs. The remaining oral direct factor Xa inhibitors may have little to no effect on major bleeding, but the evidence is very uncertain. Oral direct factor Xa inhibitors may reduce serious non-hepatic adverse events slightly compared to LMWHs. They may have little to no effect on serious hepatic adverse events, but the evidence is very uncertain. Due to the high rates of missing participants and selective outcome reporting, the effect estimates may be biased.
