Review Meta AnalysisOmega-3 fatty acids for intermittent claudication.
Peripheral artery disease (PAD) is a progressive disorder characterised by stenosis or occlusion of arteries, or both, due to arteriosclerosis. Intermittent claudication (IC) and diminished walking ability are often present as the main symptoms of PAD. Omega-3 fatty acids have been used in the treatment and prevention of coronary artery disease, although current evidence suggests they may be of limited benefit. Peripheral arterial disease and coronary artery disease share a similar pathogenesis. It is uncertain whether omega-3 fatty acids benefit people with IC. This is an update of the review first published in 2004 and updated in 2013. ⋯ The evidence is very uncertain about the effect of omega-3 fatty acids in people with intermittent claudication on quality of life, walking distance (pain-free or maximal), ankle-brachial index, and the incidence of revascularisation procedures or frequency of amputation in the lower limb. The evidence suggests that omega-3 results in little to no difference in adverse events. Further high-quality research is needed to fully evaluate short- and long-term effects of omega-3 fatty acids on the most clinically relevant outcomes in people with intermittent claudication.

Review Meta AnalysisImproving adverse drug event reporting by healthcare professionals.
Adverse drug events, encompassing both adverse drug reactions and medication errors, pose a significant threat to health, leading to illness and, in severe cases, death. Timely and voluntary reporting of adverse drug events by healthcare professionals plays a crucial role in mitigating the morbidity and mortality linked to unexpected reactions and improper medication usage. ⋯ Compared to usual practice (i.e. spontaneous reporting with or without some training from regional pharmacosurveillance units), low-certainty evidence suggests that the number of ADR reports submitted may substantially increase following an education session, paired with reminder card and ADR report form, and may slightly increase with the use of a standardised discharge form method that makes it easier for healthcare professionals to report ADRs. The evidence for other interventions identified in this review, such as informational letters or emails and financial incentives, is uncertain. Future studies need to assess the benefits (increase in the number of adverse drug event reports) and harms (increase in the number of false adverse drug event reports) of any intervention designed to improve healthcare professionals' reporting of adverse drug events. Interventions to increase the number of submitted adverse drug event reports that are suitable for use in low- and middle-income countries should be developed and rigorously evaluated.

Review Meta AnalysisUterotonics for management of retained placenta.
Retained placenta is a significant cause of maternal death from postpartum haemorrhage. Traditionally, it is managed by manual removal under anaesthesia, which carries risks of haemorrhage, infection, and uterine perforation. Uterotonics may offer an alternative for delivering the retained placenta since they induce uterine contractions. However, evidence regarding uterotonic agents for retained placenta is still limited. ⋯ Registration (13 July 2024): Prospero, CRD42024564386.

Review Meta AnalysisPerineal techniques during the second stage of labour for reducing perineal trauma and postpartum complications.
Postpartum haemorrhage (PPH) is responsible for around 27% of global maternal deaths. Perineal tears are common in vaginal births and a significant contributor to excessive blood loss. A diversity of perineal techniques are utilised to prevent perineal trauma and reduce the incidence of PPH; however, they lack evidence-based comparisons to understand their effects. ⋯ Registration and protocol: PROSPERO, CRD42024537252.

Review Meta AnalysisTopical, light-based, and complementary interventions for acne: an overview of systematic reviews.
Acne is a chronic inflammatory and immune-mediated disease of the pilosebaceous unit (the skin structure consisting of a hair follicle and its associated sebaceous gland). It is characterised by non-inflammatory lesions (open and closed comedones) and inflammatory lesions (papules, pustules, nodules, and cysts). Lesions may be present on the face, thorax, and back, with variable severity. Acne exhibits a global distribution and has a growing prevalence. Acne vulgaris is the most common form. Acne gives rise to complications such as scars and can seriously affect people's mental health, especially those with severe acne. Acne has a huge impact on the quality of life and self-esteem of those affected. ⋯ This overview summarises the evidence for topical therapy, phototherapy, and complementary therapy for acne and acne scars. We found no high-certainty evidence for the effects of any therapy included. Randomised controlled trials and systematic reviews related to acne and acne scars had limitations (low methodological quality). We could not summarise the evidence for topical retinoids and topical antibiotics due to insufficient high-quality systematic reviews. Future research should consider pooled analysis of data on new emerging drugs for acne treatment (e.g. clascoterone) and focus more on acne complications.
