Beta-blockers for the primary prevention of anthracycline-induced cardiotoxicity: a meta-analysis of randomized controlled trials.

ABSTRACT: BACKGROUND:The effects of ? blockers on the primary prevention of anthracycline-induced cardiotoxicity were controversial. METHODS:We searched PubMed, Embase and Cochrane Library for randomized controlled trials of the comparison of ? blockers versus placebo in patients undergoing anthracycline chemotherapy. This meta-analysis was performed by using random-effect models. RESULTS:Nine hundred forty participants from 11 trials were included in this meta-analysis. ? blockers led to a significant reduction in symptomatic heart failure (risk ratio [RR] 0.29, 95% CI 0.10 to 0.85). Compared with placebo, ? blockers were associated with improved left ventricular ejection fraction (mean difference [MD] 4.46, 95% CI 1.77 to 7.15) and s' (MD 0.78, 95% CI 0.01 to 1.55) in parallel with reduced left ventricular diameter (left ventricular end systolic diameter, MD -3.19, 95% CI -6.17 to -?0.21; left ventricular end diastolic diameter, MD -2.28, 95% CI 4.50 to -?0.05). ? blockers also improved strain and strain rate when compared with placebo. There were no significant differences in diastolic function variables between ? blockers and placebo except e' (MD 2.33, 95% CI 0.16 to 4.51). In addition, ? blockers compared with placebo reduced the risk of cardiac troponin I elevation >?0.04?ng/ml (RR 0.60, 95% CI 0.42 to 0.85). There was no marked difference in adverse events (RR 0.94, 95% CI 0.56 to 1.59) between ? blockers and placebo. CONCLUSIONS:In cancer patients with anthracycline therapy, prophylactic ? blockers were associated with reduced risk of heart failure, decreased left ventricular diameter, improved left ventricular systolic function, and alleviative cardiomyocyte injury.

Project description:BackgroundWe conducted a systematic review and meta-analysis to clarify the risk of early and late cardiotoxicity of anthracycline agents in patients treated for breast or ovarian cancer, lymphoma, myeloma or sarcoma.MethodsRandomized controlled trials were sought using comprehensive searches of electronic databases in June 2008. Reference lists of retrieved articles were also scanned for additional articles. Outcomes investigated were early or late clinical and sub-clinical cardiotoxicity. Trial quality was assessed, and data were pooled through meta-analysis where appropriate.ResultsFifty-five published RCTs were included; the majority were on women with advanced breast cancer. A significantly greater risk of clinical cardiotoxicity was found with anthracycline compared with non-anthracycline regimens (OR 5.43 95% confidence interval: 2.34, 12.62), anthracycline versus mitoxantrone (OR 2.88 95% confidence interval: 1.29, 6.44), and bolus versus continuous anthracycline infusions (OR 4.13 95% confidence interval: 1.75, 9.72). Risk of clinical cardiotoxicity was significantly lower with epirubicin versus doxorubicin (OR 0.39 95% confidence interval: 0.20, 0.78), liposomal versus non-liposomal doxorubicin (OR 0.18 95% confidence interval: 0.08, 0.38) and with a concomitant cardioprotective agent (OR 0.21 95% confidence interval: 0.13, 0.33). No statistical heterogeneity was found for these pooled analyses. A similar pattern of results were found for subclinical cardiotoxicity; with risk significantly greater with anthracycline containing regimens and bolus administration; and significantly lower risk with epirubicin, liposomal doxorubicin versus doxorubicin but not epirubicin, and with concomitant use of a cardioprotective agent. Low to moderate statistical heterogeneity was found for two of the five pooled analyses, perhaps due to the different criteria used for reduction in Left Ventricular Ejection Fraction. Meta-analyses of any cardiotoxicity (clinical and subclinical) showed moderate to high statistical heterogeneity for four of five pooled analyses; criteria for any cardiotoxic event differed between studies. Nonetheless the pattern of results was similar to those for clinical or subclinical cardiotoxicity described above.ConclusionsEvidence is not sufficiently robust to support clear evidence-based recommendations on different anthracycline treatment regimens, or for routine use of cardiac protective agents or liposomal formulations. There is a need to improve cardiac monitoring in oncology trials.

Project description:BackgroundTo evaluate the efficacy and safety of topical β-blockers in the treatment of superficial infantile hemangiomas (SIH) and mixed infantile hemangiomas (MIH), respectively, and compare the efficacy and safety of topical β-blockers with other interventions.MethodsThe PRISMA guidelines were adhered to. We searched for randomized controlled trials in databases from 2010 to 2018 comparing topical β-blockers with other interventions for infantile hemangiomas. The outcomes evaluated were efficacy and adverse effects. Data analyses were performed using RevMan 5.3. Publication bias was assessed to account for bias in patient selection.ResultsEleven studies, involving 1,235 patients, were subjected to this meta-analysis. Six studies compared topical β-blockers with other interventions (propranolol, placebo, corticosteroids or pulsed dye laser) in treating SIH, and 5 studies evaluated the efficacy and safety of a topical β-blocker when it was combined with another intervention in treating MIH. A topical β-blocker was discovered to be as effective as oral propranolol in treating SIH (risk ratio, RR, 0.96, 95% confidence interval, CI, 0.91-1.02, p = 0.20, I2 = 0%), and topical β-blockers were more beneficial than placebo, corticosteroids or pulsed dye laser in treating SIH (RR 2.25, 95% CI 1.66-3.05, p < 0.00001, I2 = 0%). Topical β-blockers combined with another intervention gave rise to a better clinical response in the treatment of MIH than intervention alone (RR 1.99, 95% CI 1.10-3.60, p = 0.02, I2 = 55%) (standard mean difference 0.80, 95% CI 0.28-1.31, p = 0.002, I2 = 0%). Compared with oral propranolol, topical β-blockers were associated with fewer incidences of adverse effects (RR 0.05, 95% CI 0.01-0.39, p = 0.004, I2 = 0%). No significant difference in adverse effects was found when a topical β-blocker was combined with another intervention in treating MIH (RR 1.01, 95% CI 0.58-1.74, p = 0.98, I2 = 0%).ConclusionsThis meta-analysis provided evidence that topical β-blockers may replace oral propranolol as first-line therapy for SIH and that they are of additive value in treating MIH.

Project description:A systematic review of primary prevention was conducted for cannabis use outcomes in youth and young adults. The aim of the review was to develop a comprehensive understanding of prevention programming by assessing universal, targeted, uni-modal, and multi-modal approaches as well as individual program characteristics. Twenty-eight articles, representing 25 unique studies, identified from eight electronic databases (EMBASE, MEDLINE, CINAHL, ERIC, PsycINFO, DRUG, EBM Reviews, and Project CORK), were eligible for inclusion. Results indicated that primary prevention programs can be effective in reducing cannabis use in youth populations, with statistically significant effect sizes ranging from trivial (0.07) to extremely large (5.26), with the majority of significant effect sizes being trivial to small. Given that the preponderance of significant effect sizes were trivial to small and that percentages of statistically significant and non-statistically significant findings were often equivalent across program type and individual components, the effectiveness of primary prevention for cannabis use should be interpreted with caution. Universal multi-modal programs appeared to outperform other program types (i.e, universal uni-modal, targeted multi-modal, targeted unimodal). Specifically, universal multi-modal programs that targeted early adolescents (10-13 year olds), utilised non-teacher or multiple facilitators, were short in duration (10 sessions or less), and implemented boosters sessions were associated with large median effect sizes. While there were studies in these areas that contradicted these results, the results highlight the importance of assessing the interdependent relationship of program components and program types. Finally, results indicated that the overall quality of included studies was poor, with an average quality rating of 4.64 out of 9. Thus, further quality research and reporting and the development of new innovative programs are required.
