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 AnalysisConservative, physical and surgical interventions for managing faecal incontinence and constipation in adults with central neurological diseases.
People with central neurological disease or injury have a much higher risk of both faecal incontinence (FI) and constipation than the general population. There is often a fine line between the two symptoms, with management intended to ameliorate one risking precipitating the other. Bowel problems are observed to be the cause of much anxiety and may reduce quality of life in these people. Current bowel management is largely empirical, with a limited research base. The review is relevant to individuals with any disease directly and chronically affecting the central nervous system (post-traumatic, degenerative, ischaemic or neoplastic), such as multiple sclerosis, spinal cord injury, cerebrovascular disease, Parkinson's disease and Alzheimer's disease. This is an update of a Cochrane Review first published in 2001 and subsequently updated in 2003, 2006 and 2014. ⋯ There remains little research on this common and, for patients, very significant issue of bowel management. The available evidence is almost uniformly of low methodological quality. The clinical significance of some of the research findings presented here is difficult to interpret, not least because each intervention has only been addressed in individual trials, against control rather than compared against each other, and the interventions are very different from each other. Understanding whether there is a clinically-meaningful difference from the results of available trials is largely hampered by the lack of uniform outcome measures. This is due to an absence of core outcome sets, and development of these needs to be a research priority to allow studies to be compared directly. Some studies used validated constipation, incontinence or condition-specific measures; however, others used unvalidated analogue scales to report effectiveness. Some studies did not use any patient-reported outcomes and focused on physiological outcome measures, which is of relatively limited significance in terms of clinical implementation. There was evidence in favour of some conservative interventions, but these findings need to be confirmed by larger, well-designed controlled trials, which should include evaluation of the acceptability of the intervention to patients and the effect on their quality of life.

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.
