Review Meta AnalysisUnconditional cash transfers for reducing poverty and vulnerabilities: effect on use of health services and health outcomes in low- and middle-income countries.
Unconditional cash transfers (UCTs; provided without obligation) for reducing poverty and vulnerabilities (e.g. orphanhood, old age, or HIV infection) are a social protection intervention addressing a key social determinant of health (income) in low- and middle-income countries (LMICs). The relative effectiveness of UCTs compared with conditional cash transfers (CCTs; provided only if recipients follow prescribed behaviours, e.g. use a health service or attend school) is unknown. ⋯ This body of evidence suggests that unconditional cash transfers (UCTs) may not impact a summary measure of health service use in children and adults in LMICs. However, UCTs probably or may improve some health outcomes (i.e. the likelihood of having had any illness, the likelihood of having been food secure, and the level of dietary diversity), two social determinants of health (i.e. the likelihoods of attending school and being extremely poor), and healthcare expenditure. The evidence on the relative effectiveness of UCTs and CCTs remains very uncertain.

This is an updated version of the Cochrane Review last published in Issue 7, 2019; it includes two additional studies. Epilepsy is a common neurological disease that affects approximately 1% of the UK population. Approximately one-third of these people continue to have seizures despite drug treatment. Pregabalin is one of the newer antiepileptic drugs that has been developed to improve outcomes. In this review we summarised the current evidence regarding pregabalin when used as an add-on treatment for drug-resistant focal epilepsy. ⋯ For people with drug-resistant focal epilepsy, pregabalin when used as an add-on treatment was significantly more effective than placebo at producing a 50% or greater seizure reduction and seizure freedom. Results demonstrated efficacy for doses from 150 mg/day to 600 mg/day, with increasing effectiveness at 600 mg doses, although there were issues with tolerability at higher doses. However, the trials included in this review were of short duration, and longer-term trials are needed to inform clinical decision-making. This review focused on the use of pregabalin in drug-resistant focal epilepsy, and the results cannot be generalised to add-on treatment for generalised epilepsies. Likewise, no inference can be made about the effects of pregabalin when used as monotherapy.

ReviewProstatic arterial embolization for the treatment of lower urinary tract symptoms in men with benign prostatic hyperplasia.
A variety of minimally invasive surgical approaches are available as an alternative to transurethral resection of the prostate (TURP) for management of lower urinary tract symptoms (LUTS) in men with benign prostatic hyperplasia (BPH). Prostatic arterial embolization (PAE) is a relatively new, minimally invasive treatment approach. ⋯ Compared to TURP, PAE may provide similar improvement in urologic symptom scores and quality of life. While we are very uncertain about major adverse events, PAE likely increases retreatment rates. While erectile function may be similar, PAE may reduce ejaculatory disorders. Certainty of evidence for the outcomes of this review was low or very low except for retreatment (moderate-certainty evidence), signaling that our confidence in the reported effect size is limited or very limited, and that this topic should be better informed by future research.

ReviewProbiotics for treatment of chronic constipation in children.
Functional constipation is defined as chronic constipation with no identifiable underlying cause. It is a significant cause of morbidity in children, accounting for up to 25% of visits to paediatric gastroenterologists. Probiotic preparations may sufficiently alter the gut microbiome and promote normal gut physiology in a way that helps relieve functional constipation. Several studies have sought to address this hypothesis, as well as the role of probiotics in other functional gut disorders. Therefore, it is important to have a focused review to assess the evidence to date. ⋯ There is insufficient evidence to conclude whether probiotics are efficacious in successfully treating chronic constipation without a physical explanation in children or changing the frequency of defecation, or whether there is a difference in withdrawals due to adverse events when compared with placebo. There is limited evidence from one study to suggest a synbiotic preparation may be more likely than placebo to lead to treatment success, with no difference in withdrawals due to adverse events. There is insufficient evidence to draw efficacy or safety conclusions about the use of probiotics in combination with or in comparison to any of the other interventions reported. The majority of the studies that presented data on serious adverse events reported that no events occurred. Two studies did not report this outcome. Future studies are needed to confirm efficacy, but the research community requires guidance on the best context for probiotics in such studies, considering where they should be best considered in a potential treatment hierarchy and should align with core outcome sets to support future interpretation of findings.
