Background: Insomnia has been closely associated with cardiovascular disease (CVD) including myocardial infarction (MI). Our study aims to assess the eligibility of insomnia as a potential risk factor for MI.Methods: PubMed, Scopus, and Web of Science were searched using terms; such as "Insomnia" and "MI." Only observational controlled studies with data on the incidence of MI among insomniacs were included. Revman software version 5.4 was used for the analysis.Results: Our pooled analysis showed a significant association between insomnia and the incidence of MI compared with noninsomniacs (relative risk [RR] = 1.69, 95% confidence interval [CI] = 1.41-2.02, p < .00001). Per sleep duration, we detected the highest association between ≤5 h of sleep, and MI incidence compared to 7−8 h

Background and aimRecent studies evaluated the role of vamorolone in treating Duchenne muscular dystrophy (DMD), so we aimed in our Meta-analysis to assess the efficacy of vamorolone in comparison with placebo and corticosteroids for treating DMD patients.MethodsWe searched PubMed, Web of Science, Scopus, and Cochrane library databases. We included any randomized control trials and controlled observational studies that investigated the role of vamorolone in treating DMD patients. We used RevMan software, version 5.4. to perform our meta-analysis.ResultsAfter a search of the literature, 4 studies were included in the meta-analysis; the total number of patients included in the study is 277 patients, 125 patients in the vamorolone group, 106 in the glucocorticoids group, and 46 in placebo (steroid naïve) group. The pooled analysis showed a statistically significant association between the vamorolone group and increased TTSTAND velocity, TTRW velocity and TTCLIMB velocity compared with the placebo group (MD = 0.04, 95% CI = 0.02–0.07, p = 0.002), (MD = 0.24, 95% CI = 0.11–0.37, p = 0.0003), and (MD = 0.06, 95% CI = 0.05–0.06, p &lt; 0.00001), respectively. Also, the analysis showed a statistically significant association between vamorolone and increased TTRW velocity and increased Height percentile for age compared with the glucocorticoid group (MD = −0.14, 95% CI = −0.26 to −0.01, p = 0.03) and (MD = 17.82, 95% CI = 3.89–31.75, p = 0.01), respectively.ConclusionOur study revealed a significant association between vamorolone and increased TTSTAND velocity, TTRW velocity, and TTCLIMB velocity compared with the placebo (steroid naïve), also showed a statistically significant association between increased TTRW velocity and increased Height percentile for age compared with the glucocorticoid that enhances the privilege of vamorolone over glucocorticoid in treating DMD patients. More multicenter randomized studies are needed to support our results.

Background and Aim: Some studies reported a positive relation between aortic dissection (AD) and increased lipoprotein (a) (LP(a)), while other studies reported no association, so the authors aimed to do a meta-analysis to establish the relation between AD and high levels of LP(a). Methods: PubMed, Scopus, Web of Science, SAGE, EMBASE, Science Direct, and Cochrane Library were searched. The inclusion criteria were any randomized control trials or observational studies that measured the levels of LP(a) in AD patients and healthy controls. The authors excluded case reports, case series, noncontrolled studies, reviews, editorials, and animal studies. Results: After a search of the literature, four studies were included in the meta-analysis with 678 patients included in the analysis. The pooled analysis showed a statistically significant association between the AD group and increased levels of LP(a), decreased levels of TG, low-density lipoprotein cholesterol, and TC compared with the control group (MD=11.71, 95% CI=4.11–19.32, P-value=0.003), (MD=−0,32, 95% CI=−0.48 to −0.16, P-value<0.0001 ), (MD=−0,21, 95% CI=−0.42 to −0.1, P-value=0.04), (MD=−0,58, 95% CI=−0.62 to −0.54, P-value<0.00001), respectively. Conclusion: Our study showed that AD is significantly associated with increased levels of LP(a). The significant increase in LP(a) in AD was associated with decreased levels of TG, low-density lipoprotein cholesterol, and TC. Future clinical trials testing Lp (a) targeting medications could be useful in the primary, or secondary prevention of AD in high risk patients.
