RESUMEN
BACKGROUND: Acute heart failure (AHF) is new onset of, or a sudden worsening of, chronic heart failure characterised by congestion in about 95% of cases or end-organ hypoperfusion in 5% of cases. Treatment often requires urgent escalation of diuretic therapy, mainly through hospitalisation. This Cochrane review evaluated the efficacy of intravenous loop diuretics strategies in treating AHF in individuals with New York Heart Association (NYHA) classification III or IV and fluid overload. OBJECTIVES: To assess the effects of intravenous continuous infusion versus bolus injection of loop diuretics for the initial treatment of acute heart failure in adults. SEARCH METHODS: We identified trials through systematic searches of bibliographic databases and in clinical trials registers including CENTRAL, MEDLINE, Embase, CPCI-S on the Web of Science, ClinicalTrials.gov, the World Health Organization (WHO) International Clinical Trials Registry platform (ICTRP), and the European Union Trials register. We conducted reference checking and citation searching, and contacted study authors to identify additional studies. The latest search was performed on 29 February 2024. SELECTION CRITERIA: We included randomised controlled trials (RCTs) involving adults with AHF, NYHA classification III or IV, regardless of aetiology or ejection fraction, where trials compared intravenous continuous infusion of loop diuretics with intermittent bolus injection in AHF. We excluded trials with chronic stable heart failure, cardiogenic shock, renal artery stenosis, or end-stage renal disease. Additionally, we excluded studies combining loop diuretics with hypertonic saline, inotropes, vasoactive medications, or renal replacement therapy and trials where diuretic dosing was protocol-driven to achieve a target urine output, due to confounding factors. DATA COLLECTION AND ANALYSIS: Two review authors independently screened papers for inclusion and reviewed full-texts. Outcomes included weight loss, all-cause mortality, length of hospital stay, readmission following discharge, and occurrence of acute kidney injury. We performed risk of bias assessment and meta-analysis where data permitted and assessed certainty of the evidence. MAIN RESULTS: The review included seven RCTs, spanning 32 hospitals in seven countries in North America, Europe, and Asia. Data collection ranged from eight months to six years. Following exclusion of participants in subgroups with confounding treatments and different clinical settings, 681 participants were eligible for review. These additional study characteristics, coupled with our strict inclusion and exclusion criteria, improve the applicability of the body of the evidence as they reflect real-world clinical practice. Meta-analysis was feasible for net weight loss, all-cause mortality, length of hospital stay, readmission, and acute kidney injury. Literature review and narrative analysis explored daily fluid balance; cardiovascular mortality; B-type natriuretic peptide (BNP) change; N-terminal-proBNP change; and adverse incidents such as ototoxicity, hypotension, and electrolyte imbalances. Risk of bias assessment revealed two studies with low overall risk, four with some concerns, and one with high risk. All sensitivity analyses excluded trials at high risk of bias. Only narrative analysis was conducted for 'daily fluid balance' due to diverse data presentation methods across two studies (169 participants, the evidence was very uncertain about the effect). Results of narrative analysis varied. For instance, one study reported higher daily fluid balance within the first 24 hours in the continuous infusion group compared to the bolus injection group, whereas there was no difference in fluid balance beyond this time point. Continuous intravenous infusion of loop diuretics may result in mean net weight loss of 0.86 kg more than bolus injection of loop diuretics, but the evidence is very uncertain (mean difference (MD) 0.86 kg, 95% confidence interval (CI) 0.44 to 1.28; 5 trials, 497 participants; P < 0.001, I2 = 21%; very low-certainty evidence). Importantly, sensitivity analysis excluding trials with high risk of bias showed there was insufficient evidence for a difference in bodyweight loss between groups (MD 0.70 kg, 95% CI -0.06 to 1.46; 3 trials, 378 participants; P = 0.07, I2 = 0%). There may be little to no difference in all-cause mortality between continuous infusion and bolus injection (risk ratio (RR) 1.53, 95% CI 0.81 to 2.90; 5 trials, 530 participants; P = 0.19, I2 = 4%; low-certainty evidence). Despite sensitivity analysis, the direction of the evidence remained unchanged. No trials measured cardiovascular mortality. There may be little to no difference in the length of hospital stay between continuous infusion and bolus injection of loop diuretics, but the evidence is very uncertain (MD -1.10 days, 95% CI -4.84 to 2.64; 4 trials, 211 participants; P = 0.57, I2 = 88%; very low-certainty evidence). Sensitivity analysis improved heterogeneity; however, the direction of the evidence remained unchanged. There may be little to no difference in the readmission to hospital between continuous infusion and bolus injection of loop diuretics (RR 0.85, 95% CI 0.63 to 1.16; 3 trials, 400 participants; P = 0.31, I2 = 0%; low-certainty evidence). Sensitivity analysis continued to show insufficient evidence for a difference in the readmission to hospital between groups. There may be little to no difference in the occurrence of acute kidney injury as an adverse event between continuous infusion and bolus injection of intravenous loop diuretics (RR 1.02, 95% CI 0.70 to 1.49; 3 trials, 491 participants; P = 0.92, I2 = 0%; low-certainty evidence). Sensitivity analysis continued to show that continuous infusion may make little to no difference on the occurrence of acute kidney injury as an adverse events compared to the bolus injection of intravenous loop diuretics. AUTHORS' CONCLUSIONS: Analysis of available data comparing two delivery methods of diuretics in acute heart failure found that the current data are insufficient to show superiority of one strategy intervention over the other. Our findings were based on trials meeting stringent inclusion and exclusion criteria to ensure validity. Despite previous reviews suggesting advantages of continuous infusion over bolus injections, our review found insufficient evidence to support or refute this. However, our review, which excluded trials with clinical confounders and RCTs with high risk of bias, offers the most robust conclusion to date.

BACKGROUND: Prenatal exposure to certain anti-seizure medications (ASMs) is associated with an increased risk of major congenital malformations (MCM). The majority of women with epilepsy continue taking ASMs throughout pregnancy and, therefore, information on the potential risks associated with ASM treatment is required. OBJECTIVES: To assess the effects of prenatal exposure to ASMs on the prevalence of MCM in the child. SEARCH METHODS: For the latest update of this review, we searched the following databases on 17 February 2022: Cochrane Register of Studies (CRS Web), MEDLINE (Ovid, 1946 to February 16, 2022), SCOPUS (1823 onwards), and ClinicalTrials.gov, WHO International Clinical Trials Registry Platform (ICTRP). No language restrictions were imposed. SELECTION CRITERIA: We included prospective cohort controlled studies, cohort studies set within pregnancy registries, randomised controlled trials and epidemiological studies using routine health record data. Participants were women with epilepsy taking ASMs; the two control groups were women without epilepsy and untreated women with epilepsy. DATA COLLECTION AND ANALYSIS: Five authors independently selected studies for inclusion. Eight authors completed data extraction and/or risk of bias assessments. The primary outcome was the presence of an MCM. Secondary outcomes included specific types of MCM. Where meta-analysis was not possible, we reviewed included studies narratively. MAIN RESULTS: From 12,296 abstracts, we reviewed 283 full-text publications which identified 49 studies with 128 publications between them. Data from ASM-exposed pregnancies were more numerous for prospective cohort studies (n = 17,963), than data currently available for epidemiological health record studies (n = 7913). The MCM risk for children of women without epilepsy was 2.1% (95% CI 1.5 to 3.0) in cohort studies and 3.3% (95% CI 1.5 to 7.1) in health record studies. The known risk associated with sodium valproate exposure was clear across comparisons with a pooled prevalence of 9.8% (95% CI 8.1 to 11.9) from cohort data and 9.7% (95% CI 7.1 to 13.4) from routine health record studies. This was elevated across almost all comparisons to other monotherapy ASMs, with the absolute risk differences ranging from 5% to 9%. Multiple studies found that the MCM risk is dose-dependent. Children exposed to carbamazepine had an increased MCM prevalence in both cohort studies (4.7%, 95% CI 3.7 to 5.9) and routine health record studies (4.0%, 95% CI 2.9 to 5.4) which was significantly higher than that for the children born to women without epilepsy for both cohort (RR 2.30, 95% CI 1.47 to 3.59) and routine health record studies (RR 1.14, 95% CI 0.80 to 1.64); with similar significant results in comparison to the children of women with untreated epilepsy for both cohort studies (RR 1.44, 95% CI 1.05 to 1.96) and routine health record studies (RR 1.42, 95% CI 1.10 to 1.83). For phenobarbital exposure, the prevalence was 6.3% (95% CI 4.8 to 8.3) and 8.8% (95% CI 0.0 to 9277.0) from cohort and routine health record data, respectively. This increased risk was significant in comparison to the children of women without epilepsy (RR 3.22, 95% CI 1.84 to 5.65) and those born to women with untreated epilepsy (RR 1.64, 95% CI 0.94 to 2.83) in cohort studies; data from routine health record studies was limited. For phenytoin exposure, the prevalence of MCM was elevated for cohort study data (5.4%, 95% CI 3.6 to 8.1) and routine health record data (6.8%, 95% CI 0.1 to 701.2). The prevalence of MCM was higher for phenytoin-exposed children in comparison to children of women without epilepsy (RR 3.81, 95% CI 1.91 to 7.57) and the children of women with untreated epilepsy (RR 2.01. 95% CI 1.29 to 3.12); there were no data from routine health record studies. Pooled data from cohort studies indicated a significantly increased MCM risk for children exposed to lamotrigine in comparison to children born to women without epilepsy (RR 1.99, 95% CI 1.16 to 3.39); with a risk difference (RD) indicating a 1% increased risk of MCM (RD 0.01. 95% CI 0.00 to 0.03). This was not replicated in the comparison to the children of women with untreated epilepsy (RR 1.04, 95% CI 0.66 to 1.63), which contained the largest group of lamotrigine-exposed children (> 2700). Further, a non-significant difference was also found both in comparison to the children of women without epilepsy (RR 1.19, 95% CI 0.86 to 1.64) and children born to women with untreated epilepsy (RR 1.00, 95% CI 0.79 to 1.28) from routine data studies. For levetiracetam exposure, pooled data provided similar risk ratios to women without epilepsy in cohort (RR 2.20, 95% CI 0.98 to 4.93) and routine health record studies (RR 0.67, 95% CI 0.17 to 2.66). This was supported by the pooled results from both cohort (RR 0.71, 95% CI 0.39 to 1.28) and routine health record studies (RR 0.82, 95% CI 0.39 to 1.71) when comparisons were made to the offspring of women with untreated epilepsy. For topiramate, the prevalence of MCM was 3.9% (95% CI 2.3 to 6.5) from cohort study data and 4.1% (0.0 to 27,050.1) from routine health record studies. Risk ratios were significantly higher for children exposed to topiramate in comparison to the children of women without epilepsy in cohort studies (RR 4.07, 95% CI 1.64 to 10.14) but not in a smaller comparison to the children of women with untreated epilepsy (RR 1.37, 95% CI 0.57 to 3.27); few data are currently available from routine health record studies. Exposure in utero to topiramate was also associated with significantly higher RRs in comparison to other ASMs for oro-facial clefts. Data for all other ASMs were extremely limited. Given the observational designs, all studies were at high risk of certain biases, but the biases observed across primary data collection studies and secondary use of routine health records were different and were, in part, complementary. Biases were balanced across the ASMs investigated, and it is unlikely that the differential results observed across the ASMs are solely explained by these biases. AUTHORS' CONCLUSIONS: Exposure in the womb to certain ASMs was associated with an increased risk of certain MCMs which, for many, is dose-dependent.
ANTECEDENTES: La exposición prenatal a determinados fármacos anticonvulsivos (FAC) se asocia con un mayor riesgo de malformaciones congénitas graves (MCG). La mayoría de las mujeres con epilepsia continúan tomando FAC durante todo el embarazo y, por lo tanto, se requiere información sobre los riesgos potenciales asociados con el tratamiento con FAC. OBJETIVOS: Evaluar los efectos de la exposición prenatal a los FAC sobre la prevalencia de MCG en el niño. MÉTODOS DE BÚSQUEDA: Para la última actualización de esta revisión se hicieron búsquedas el 17 de febrero de 2022 en las siguientes bases de datos: Registro Cochrane de Estudios (Cochrane Register of Studies [CRS Web]), MEDLINE (Ovid, 1946 hasta el 16 de febrero de 2022), SCOPUS (1823 en adelante) y ClinicalTrials.gov , Plataforma de registros internacionales de ensayos clínicos (ICTRP). No se impusieron restricciones de idioma. CRITERIOS DE SELECCIÓN: Se incluyeron estudios prospectivos controlados de cohortes, estudios de cohortes establecidos dentro de registros de embarazos, ensayos controlados aleatorizados y estudios epidemiológicos que utilizaron datos rutinarios de los historiales médicos. Las participantes fueron mujeres con epilepsia que tomaban FAC; los dos grupos de control fueron mujeres sin epilepsia y mujeres con epilepsia que no recibían tratamiento. OBTENCIÓN Y ANÁLISIS DE LOS DATOS: Cinco autores seleccionaron de forma independiente los estudios para inclusión. Ocho autores completaron la extracción de los datos y las evaluaciones del riesgo de sesgo. El desenlace principal fue la presencia de una MCG. Los desenlaces secundarios incluyeron tipos específicos de MCG. Cuando no fue posible realizar un metanálisis, los estudios incluidos se examinaron de forma narrativa. RESULTADOS PRINCIPALES: De 12 296 resúmenes, se revisaron 283 publicaciones a texto completo que identificaron 49 estudios con 128 publicaciones entre ellos. Los datos de los embarazos expuestos a FAC fueron más numerosos en el caso de los estudios prospectivos de cohortes (n = 17 963), que los datos actualmente disponibles de estudios de registros sanitarios epidemiológicos (n = 7913). El riesgo de MCG en los hijos de mujeres sin epilepsia fue del 2,1% (IC del 95%: 1,5 a 3,0) en los estudios de cohortes y del 3,3% (IC del 95%: 1,5 a 7,1) en los estudios de registros sanitarios. El riesgo conocido asociado con la exposición al valproato de sodio fue evidente en todas las comparaciones, con una prevalencia agrupada del 9,8% (IC del 95%: 8,1 a 11,9) a partir de los datos de los estudios de cohortes y del 9,7% (IC del 95%: 7,1 a 13,4) a partir de los estudios con datos rutinarios de los historiales médicos. Este fue elevado en casi todas las comparaciones con otros FAC como monoterapia, con diferencias absolutas de riesgo que variaron entre el 5% y el 9%. Múltiples estudios han constatado que el riesgo de MCG depende de la dosis. Los niños expuestos a la carbamazepina tuvieron una mayor prevalencia de MCG tanto en los estudios de cohortes (4,7%; IC del 95%: 3,7 a 5,9) como en los estudios con datos rutinarios de los historiales médicos (4,0%; IC del 95%: 2,9 a 5,4), que fue significativamente superior a la de los niños nacidos de mujeres sin epilepsia tanto en los estudios de cohortes (RR 2,30; IC del 95%: 1,47 a 3,59) como en los estudios de historias clínicas habituales (RR 1,14; IC del 95%: 0,80 a 1,64), con resultados significativos similares en comparación con los hijos de mujeres con epilepsia que no reciben tratamiento tanto en los estudios de cohortes (RR 1,44; IC del 95%: 1,05 a 1,96) como en los estudios con datos rutinarios de los historiales médicos (RR 1,42; IC del 95%: 1,10 a 1,83). Para la exposición al fenobarbital, la prevalencia fue del 6,3% (IC del 95%: 4,8 a 8,3) y del 8,8% IC del 95%: 0,0 a 9277,0) a partir de los datos de estudios de cohortes y los datos de estudios con datos rutinarios de los historiales médicos, respectivamente. Este aumento del riesgo fue significativo en comparación con los hijos de mujeres sin epilepsia (RR 3,22; IC del 95%: 1,84 a 5,65) y los nacidos de mujeres con epilepsia que no reciben tratamiento (RR 1,64; IC del 95%: 0,94 a 2,83) en estudios de cohortes; los datos procedentes de estudios con datos rutinarios de los historiales médicos fueron limitados. En cuanto a la exposición a la fenitoína, la prevalencia de MCG fue elevada en los datos de los estudios de cohortes (5,4%; IC del 95%: 3,6 a 8,1) y en los datos rutinarios de los historiales médicos (6,8%; IC del 95%: 0,1 a 701,2). La prevalencia de MCG fue mayor en los niños expuestos a la fenitoína en comparación con los hijos de mujeres sin epilepsia (RR 3,81; IC del 95%: 1,91 a 7,57) y los hijos de mujeres con epilepsia que no reciben tratamiento (RR 2,01; IC del 95%: 1,29 a 3,12); no hubo datos procedentes de estudios con datos rutinarios de los historiales médicos. Los datos agrupados de los estudios de cohortes indicaron un riesgo significativamente mayor de MCG en los niños expuestos a lamotrigina en comparación con los niños nacidos de mujeres sin epilepsia (RR 1,99; IC del 95%: 1,16 a 3,39); con una diferencia de riesgos (DR) que indica un riesgo 1% mayor de MCG (DR 0,01. IC del 95%: 0,00 a 0,03). Esto no se repitió en la comparación con los hijos de las mujeres con epilepsia que no reciben tratamiento (RR 1,04; IC del 95%: 0,66 a 1,63), que contenía el mayor grupo de niños expuestos a la lamotrigina (> 2700). Además, también se encontró una diferencia no significativa tanto en comparación con los hijos de mujeres sin epilepsia (RR 1,19; IC del 95%: 0,86 a 1,64) como con los hijos de mujeres con epilepsia que no reciben tratamiento (RR 1,00; IC del 95%: 0,79 a 1,28) a partir de los estudios con datos rutinarios. Para la exposición al levetiracetam, los datos agrupados proporcionaron razones de riesgos similares a las de las mujeres sin epilepsia en los estudios de cohortes (RR 2,20; IC del 95%: 0,98 a 4,93) y en los estudios con datos rutinarios de los historiales médicos (RR 0,67; IC del 95%: 0,17 a 2,66). Los resultados agrupados de los estudios de cohortes (RR: 0,71; IC del 95%: 0,39 a 1,28) y de los estudios con datos rutinarios de los historiales médicos (RR: 0,82; IC del 95%: 0,39 a 1,71) respaldan esta afirmación cuando se comparan con los hijos de las mujeres con epilepsia que no reciben tratamiento. En el caso del topiramato, la prevalencia de MCG fue del 3,9% (IC del 95%: 2,3 a 6,5) a partir de los datos de los estudios de cohortes y del 4,1% (0,0 a 27.050,1) a partir de los estudios con datos rutinarios de los historiales médicos. Las razones de riesgos fueron significativamente más altas para los niños expuestos al topiramato en comparación con los hijos de mujeres sin epilepsia en estudios de cohortes (RR 4,07; IC del 95%: 1,64 a 10,14), pero no en una comparación más pequeña con los hijos de mujeres con epilepsia que no reciben tratamiento (RR 1,37; IC del 95%: 0,57 a 3,27); actualmente se dispone de pocos datos a partir de estudios con datos rutinarios de los historiales médicos. La exposición en el útero al topiramato también se asoció con RR significativamente mayores en comparación con otros FAC para las hendiduras orofaciales. Los datos de todos las demás FAC fueron extremadamente limitados. Debido a los diseños observacionales, todos los estudios presentaron un alto riesgo de ciertos sesgos, pero los sesgos observados en los estudios de obtención de datos primarios y el uso secundario de historiales médicos rutinarios fueron diferentes y, en parte, complementarios. Los sesgos estaban equilibrados entre los FAC investigados, y es poco probable que los resultados diferenciales observados entre los FAC se expliquen únicamente por estos sesgos. CONCLUSIONES DE LOS AUTORES: La exposición en el útero a ciertos FAC se asoció con un mayor riesgo de ciertos MCG que, para muchos, depende de la dosis.

PURPOSE: Physical activity can improve health outcomes for cancer patients; however, only 30% of patients are physically active. This review explored barriers to and facilitators of physical activity promotion and participation in patients living with and beyond cancer. Secondary aims were to (1) explore similarities and differences in barriers and facilitators experienced in head and neck cancer versus other cancers, and (2) identify how many studies considered the influence of socioeconomic characteristics on physical activity behaviour. METHODS: CINAHL Plus, MEDLINE, PsycINFO, Scopus and Cochrane (CDSR) were searched for qualitative and mixed methods evidence. Quality assessment was conducted using the Mixed Methods Appraisal Tool and a Critical Appraisal Skills Programme Tool. Thematic synthesis and frequency of reporting were conducted, and results were structured using the Capability-Opportunity-Motivation-Behaviour model and Theoretical Domains Framework. RESULTS: Thirty qualitative and six mixed methods studies were included. Socioeconomic characteristics were not frequently assessed across the included studies. Barriers included side effects and comorbidities (physical capability; skills) and lack of knowledge (psychological capability; knowledge). Having a dry mouth or throat and choking concerns were reported in head and neck cancer, but not across other cancers. Facilitators included improving education (psychological capability; knowledge) on the benefits and safety of physical activity. CONCLUSION: Educating patients and healthcare professionals on the benefits and safety of physical activity may facilitate promotion, uptakeand adherence. Head and neck cancer patients experienced barriers not cited across other cancers, and research exploring physical activity promotion in this patient group is required to improve physical activity engagement.

BACKGROUND: Epilepsy is one of the most common neurological disorders. Approximately 30% of people with epilepsy are considered to be drug-resistant, and usually need treatment with a combination of other antiepileptic drugs. Perampanel is a newer antiepileptic drug that has been investigated as add-on therapy for drug-resistant focal epilepsy. OBJECTIVES: To evaluate the benefits and harms of perampanel as add-on therapy for people with drug-resistant focal epilepsy. SEARCH METHODS: We used standard, extensive Cochrane search methods. The latest search date was 20 October 2022. SELECTION CRITERIA: We included randomised controlled trials comparing add-on perampanel with placebo. DATA COLLECTION AND ANALYSIS: We used standard Cochrane methods. Our primary outcome was 1. 50% or greater reduction in seizure frequency. Our secondary outcomes were 2. seizure freedom, 3. treatment withdrawal due to any reason, 4. treatment withdrawal due to adverse effects, and 5. ADVERSE EFFECTS: We used an intention-to-treat population for all primary analyses. We presented the results as risk ratios (RR) with 95% confidence intervals (CIs), except for individual adverse effects, which we reported with 99% CIs to compensate for multiple testing. We used GRADE to assess certainty of evidence for each outcome. MAIN RESULTS: We included seven trials involving 2524 participants, all aged over 12 years. The trials were double-blind, randomised, placebo-controlled trials with treatment duration of 12 to 19 weeks. We assessed four trials at overall low risk of bias, and three trials at overall unclear risk of bias, due to risk of detection, reporting, and other biases. Compared with placebo, participants receiving perampanel were more likely to achieve a 50% or greater reduction in seizure frequency (RR 1.67, 95% CI 1.43 to 1.95; 7 trials, 2524 participants; high-certainty evidence). Compared to placebo, perampanel increased seizure freedom (RR 2.50, 95% CI 1.38 to 4.54; 5 trials, 2323 participants; low-certainty evidence) and treatment withdrawal (RR 1.30, 95% CI 1.03 to 1.63; 7 trials, 2524 participants; low-certainty evidence). Participants treated with perampanel were more likely to withdraw from treatment due to adverse effects compared to those receiving placebo (RR 2.36, 95% CI 1.59 to 3.51; 7 trials, 2524 participants; low-certainty evidence). A higher proportion of participants receiving perampanel reported one or more adverse effects when compared to participants who received placebo (RR 1.17, 95% CI 1.10 to 1.24; 7 trials, 2524 participants; high-certainty evidence). Compared with placebo, participants receiving perampanel were more likely to experience ataxia (RR 14.32, 99% CI 1.09 to 188.31; 2 trials, 1098 participants; low-certainty evidence), dizziness (RR 2.87, 99% CI 1.45 to 5.70; 7 trials, 2524 participants; low-certainty evidence), and somnolence (RR 1.76, 99% CI 1.02 to 3.04; 7 trials, 2524 participants). Subgroup analysis indicated that a larger proportion of participants who received perampanel at a dose of 4 mg/day (RR 1.38, 95% CI 1.05 to 1.83; 2 trials, 710 participants), 8 mg/day (RR 1.83, 95% CI 1.51 to 2.22; 4 trials, 1227 participants), or 12 mg/day (RR 2.38, 95% CI 1.86 to 3.04; 3 trials, 869 participants) achieved a 50% or greater reduction in seizure frequency compared to placebo; however, treatment with perampanel 12 mg/day also increased treatment withdrawal (RR 1.77, 95% CI 1.31 to 2.40; 3 trials, 869 participants). AUTHORS' CONCLUSIONS: Add-on perampanel is effective at reducing seizure frequency and may be effective at maintaining seizure freedom for people with drug-resistant focal epilepsy. Although perampanel was well-tolerated, there was a higher proportion of treatment withdrawals with perampanel compared with placebo. Subgroup analysis suggested that 8 mg/day and 12 mg/day are the most efficacious perampanel doses; however, the use of 12 mg/day would likely increase the number of treatment withdrawals. Future research should focus on investigating the efficacy and tolerability of perampanel with longer-term follow-up, as well as exploring an optimal dose.

INTRODUCTION: Atrial fibrillation (AF) is the most common cardiac arrhythmia in critically unwell patients. New-onset AF (NOAF) affects 5%-11% of all admissions and up to 46% admitted with septic shock. NOAF is associated with increased morbidity, mortality and healthcare costs. Existing trials into the prevention and management of NOAF suffer from significant heterogeneity making comparisons and inferences limited. Core outcome sets (COS) aim to standardise outcome reporting, reduce inconsistency between trials and reduce outcome reporting bias. We aim to develop an internationally agreed COS for trials of interventions on the management of NOAF during critical illness. METHODS AND ANALYSIS: Stakeholders including intensive care physicians, cardiologists and patients will be recruited from national and international critical care organisations. COS development will occur in five stages: (1) Outcomes included in trials, recent systematic reviews and surveys of clinician practice and patient focus groups will be extracted. (2) Extracted outcomes will inform a two-stage e-Delphi process and consensus meeting using Grading of Recommendations Assessment, Development and Evaluation methodology. (3) Outcome measurement instruments (OMIs) will be identified from the literature and a consensus meeting held to agree OMI for core outcomes. (4) Nominal group technique will be used in a final consensus meeting to the COS. (5) The findings of our COS will be published in peer-reviewed journals and implemented in future guidelines and intervention trials. ETHICS AND DISSEMINATION: The study has been approved by the University of Liverpool ethics committee (Ref: 11 256, 21 June 2022), with a formal consent waiver and assumed consent. We will disseminate the finalised COS via national and international critical care organisations and publication in peer-reviewed journals.

OBJECTIVE: To determine which service models and organisational structures are effective and cost-effective for delivering tuberculosis (TB) services to hard-to-reach populations. DESIGN: Embase and MEDLINE (1990-2017) were searched in order to update and extend the 2011 systematic review commissioned by National Institute for Health and Care Excellence (NICE), discussing interventions targeting service models and organisational structures for the identification and management of TB in hard-to-reach populations. The NICE and Cochrane Collaboration standards were followed. SETTING: European Union, European Economic Area, European Union candidate countries and Organisation for Economic Co-operation and Development countries. PARTICIPANTS: Hard-to-reach populations, including migrants, homeless people, drug users, prisoners, sex workers, people living with HIV and children within vulnerable and hard-to-reach populations. PRIMARY AND SECONDARY OUTCOME MEASURES: Effectiveness and cost-effectiveness of the interventions. RESULTS: From the 19 720 citations found, five new studies were identified, in addition to the six discussed in the NICE review. Community health workers from the same migrant community, street teams and peers improved TB screening uptake by providing health education, promoting TB screening and organising contact tracing. Mobile TB clinics, specialised TB clinics and improved cooperation between healthcare services can be effective at identifying and treating active TB cases and are likely to be cost-effective. No difference in treatment outcome was detected when directly observed therapy was delivered at a health clinic or at a convenient location in the community. CONCLUSIONS: Although evidence is limited due to the lack of high-quality studies, interventions using peers and community health workers, mobile TB services, specialised TB clinics and improved cooperation between health services can be effective to control TB in hard-to-reach populations. Future studies should evaluate the (cost-)effectiveness of interventions on TB identification and management in hard-to-reach populations and countries should be urged to publish the outcomes of their TB control systems.

Tuberculosis disproportionately affects hard-to-reach populations, such as homeless people, migrants, refugees, prisoners, or drug users. These people often face challenges in accessing quality health care. We did a systematic review of the qualitative literature to identify barriers and facilitators to the uptake of tuberculosis diagnostic and treatment services by people from hard-to-reach populations in all European Union (EU), European Economic Area, EU candidate, and Organisation for Economic Co-operation and Development countries. The 12 studies included in this review mainly focused on migrants. Views on perceived susceptibility to and severity of tuberculosis varied widely and included many misconceptions. Stigma and challenges regarding access to health care were identified as barriers to tuberculosis diagnosis and treatment uptake, whereas support from nurses, family, and friends was a facilitator for treatment adherence. Further studies are required to identify barriers and facilitators to the improved identification and management of tuberculosis in hard-to-reach populations to inform recommendations for more effective tuberculosis control programmes.

Tuberculosis is over-represented in hard-to-reach (underserved) populations in high-income countries of low tuberculosis incidence. The mainstay of tuberculosis care is early detection of active tuberculosis (case finding), contact tracing, and treatment completion. We did a systematic review with a scoping component of relevant studies published between 1990 and 2015 to update and extend previous National Institute for Health and Care Excellence (NICE) reviews on the effectiveness of interventions for identifying and managing tuberculosis in hard-to-reach populations. The analyses showed that tuberculosis screening by (mobile) chest radiography improved screening coverage and tuberculosis identification, reduced diagnostic delay, and was cost-effective among several hard-to-reach populations. Sputum culture for pre-migration screening and active referral to a tuberculosis clinic improved identification. Furthermore, monetary incentives improved tuberculosis identification and management among drug users and homeless people. Enhanced case management, good cooperation between services, and directly observed therapy improved treatment outcome and compliance. Strong conclusions cannot be drawn because of the heterogeneity of evidence with regard to study population, methodology, and quality.

OBJECTIVES: To undertake a systematic review of the clinical effectiveness of routine percutaneous transluminal coronary angioplasty (PTCA) plus stenting vs PTCA alone. DATA SOURCES: MEDLINE; EMBASE; Science Citation Index; The Cochrane Library; cardiovascular journals and conference proceedings; Internet resources (including industry supported web pages); and reference lists of included studies and relevant reviews. REVIEW METHODS: Study selection included published and unpublished randomized controlled trials (RCTs) comparing the use of coronary stents to PTCA. Outcome measures assessed included death, acute myocardial infarction (AMI), event rate (such as major cardiac adverse events (MACE) or other composite measures), and binary restenosis (BR). Data extraction and quality assessment were conducted according to internationally recognized methods. Data synthesis included meta-analysis of assessed outcomes, reported as odds ratios (ORs). RESULTS: Fifty RCTs involving 16,500 patients met the inclusion criteria (39 full articles, 11 abstracts). Of these, 23 studies compared stenting with PTCA in patients with non-specific coronary artery disease (CAD), 11 compared stents with PTCA following AMI, 8 included patients with small coronary arteries and 8 included patients whose vessels had chronic total occlusion. There were no differences in rates of death or AMI. There were reductions in the rates of MACE (death, AMI or revascularization) with stents compared to PTCA (at 6 months, for non-specific group OR: 1.64, 95% CI 1.44-1.87; for AMI group OR: 2.36, 95% CI 1.92-2.89; for small vessel group OR: 1.38, 95% CI 1.10-1.74; at 12 months, for non-specific group OR: 1.31, 95% CI 1.11-1.55; for AMI OR: 2.26, 95% CI 1.47-3.46). Reporting of combined major adverse cardiac events was inconsistent across studies. Most events were revascularizations that may have been partly driven by protocol-required angiograms. Stents reduced BR rates at angiogram at 6 months compared to PTCA in all groups. CONCLUSION: We found no differences in mortality or AMI, but the studies were not powered to identify changes in these endpoints. Coronary stenting is associated with reduced restenosis and combined adverse cardiac events, primarily revascularizations. However, the frequency of revascularization may have been distorted by protocol-dictated angiography.

AIMS: To provide systematic assessment of the clinical effectiveness of drug-eluting stents (DES) versus non-DES to inform national guidance. METHODS AND RESULTS: The review was conducted according to internationally recognised methods. The search strategy identified published (7) and unpublished (7) randomised controlled trials comparing the use of DES to non-DES. Outcomes included death, acute myocardial infarction (AMI), revascularisation, event rate (composite of adverse events), and binary restenosis. Data synthesis included descriptive statistics and meta-analysis. Fourteen randomised clinical trials comparing DES to non-DES and involving 5747 patients were identified. There were reductions in event rates between DES and non-DES; odds ratio (OR) 0.63 (95% confidence interval [95% CI] 0.47, 0.84, n = 1978) for paclitaxel-eluting stents at 12 months, OR 0.30 (95% CI 0.22, 0.42, n = 1296) for sirolimus-eluting stents at 12 months. Combined event rates were inconsistently defined across trials and were primarily composed of revascularisations, possibly driven by protocol-required angiograms. DES reduced binary restenosis rates at angiogram compared to non-DES. No significant differences in rates of death or AMI were identified. CONCLUSION: The early data available indicate that DES reduce adverse cardiac events, mainly revascularisations. However, these data are limited in terms of patient numbers, length of follow-up, and method of outcome assessment. The evaluation of rapidly evolving technologies requires the inclusion of data not routinely considered for inclusion in systematic reviews of effectiveness.
