Objective: The optimal management for cervical artery dissection (CAD) is uncertain. This study aimed to summarize the current randomized controlled trials (RCTs) to compare the efficacy and safety of antiplatelet and anticoagulation therapies for CAD.Methods: A literature search was conducted in the major databases, such as MEDLINE, Embase, and the Cochrane Library. Only the RCTs comparing the antiplatelet and anticoagulation therapies for the patients with CAD were included. Combined estimates of the relative risk (RR) of antiplatelet vs. anticoagulation were analyzed. Heterogeneity was measured using the I2 statistical analysis. The analyses were performed in the intention-to-treat (ITT) and per-protocol (PP) population, respectively.Results: Two RCTs involving 444 patients in the ITT population and 370 patients in the PP population were included. The quality of studies was high overall. In the ITT population, compared with the patients in the anticoagulation group, the patients in the antiplatelet group showed a higher rate of ischemic stroke within 3 months (RR = 6.73 [95% CI, 1.22–37.15], I2 = 0%, P = 0.029). No difference between these two treatment groups was found for the outcomes of transient ischemic attack (RR = 0.37 [95% CI, 0.09–1.58], I2 = 0%, P = 0.181), intracranial hemorrhage (RR = 0.33 [95% CI, 0.01–7.98], I2 = 0%, P = 0.494), major extracranial bleeding (RR = 0.31 [95% CI, 0.01–7.60], I2 = 0%, P = 0.476), or the composite of these outcomes within 3 months. For the PP population, the results of the meta-analysis of outcomes between the antiplatelet and anticoagulation groups were consistent with the ITT population.Conclusions: Compared with the antiplatelet group, the anticoagulation group has a lower risk of ischemic stroke without increasing bleeding risk when treating CAD. Anticoagulation seems to be superior over the antiplatelet in treating CAD but needs to be further tested by specifying several issues, such as location, initial symptom types, and treatment protocols.

Abstract Background: Although multiple randomized controlled trials (RCTs) and meta-analyses have been conducted on the issue of acute phase anti-hypertensive therapies for ischemic stroke (IS) patients, many studies have failed to enhance blood pressure (BP) decrease after these treatments. The effects of effective acute anti-hypertensive therapies on IS prognosis are still unclear.Methods: Published literature was systematically searched in PubMed, Embase and Cochrane Library. Multiple RCTs that included IS patients, in which there was a significant BP decrease in the anti-hypertensive intervention group compared with the control group within 72 h after the onset of stroke, were identified. A meta-analysis was conducted to assess the effects of such therapy on the functional outcome, mortality, and multiple severe adverse events (SAEs) of IS patients.Results: Eight RCTs were included in this study, with a total of 9427 IS patients. According to this meta-analysis, with significant BP differences between the treatment and control groups within 72 h from stroke onset, effective acute anti-hypertensive therapy has a neutral effect on multiple IS prognostic factors, including functional outcome (RR 1.03, 95% CI 0.93-1.13), mortality (RR 1.10, 95% CI 0.89-1.35), and multiple SAEs.Conclusions: Based on current studies, effective acute anti-hypertensive therapy did not improve the prognosis of IS patients, including functional outcome, mortality, and SAEs. There is no evidence that such therapy is beneficial in clinical practice.

Cerebrolysin was reported to be effective in the neurological improvement of patients with acute ischemic stroke (AIS) in experimental models, while data from clinical trials were inconsistent. We performed a meta-analysis to explore the efficacy and safety of cerebrolysin for AIS. PubMed, EMBASE, and Cochrane Library were searched for randomized controlled trials, which intervened within 72 hours after the stroke onset. We investigated the efficacy and safety outcomes, respectively. Risk ratios and mean differences were pooled with fixed-effects model or random-effects model. Seven studies were identified, involving 1779 patients with AIS. The summary results failed to demonstrate significant superiority of cerebrolysin in the assessment of efficacy outcomes of mRS and BI. Similarly, administration of cerebrolysin had neutral effects on safety outcomes compared with placebo, including mortality and SAE. However, the number of included studies was small, especially in the analysis of efficacy outcomes, which might cause publication bias and inaccurate between-studies variance in the meta-analysis. Conclusively, although it seemed to be safe, routine use of cerebrolysin to improve the long-term rehabilitation after stroke could not be supported by available evidence.

The role of adjuvant transarterial chemoembolization (TACE) for patients with resectable hepatocellular carcinoma (HCC) undergoing hepatectomy is currently unclear. We performed a systematic review of the literature using the MEDLINE, Embase, and Cochrane Library databases. Random-effects meta-analysis was carried out to compare the overall survival (OS) and recurrence-free survival (RFS) of patients with resectable HCC undergoing hepatectomy followed by adjuvant TACE vs. hepatectomy alone in randomized controlled trials (RCTs). The risk of bias was assessed using the Risk of Bias 2.0 tool. Meta-regression analyses were performed to explore the effect of hepatitis B viral status, microvascular invasion, type of resection (anatomic vs. parenchymal-sparing), and tumor size on the outcomes. Ten eligible RCTs, reporting on 1216 patients in total, were identified. The combination of hepatectomy and adjuvant TACE was associated with superior OS (hazard ratio (HR): 0.66, 95% confidence interval (CI): 0.52 to 0.85; p < 0.001) and RFS (HR: 0.70, 95% CI: 0.56 to 0.88; p < 0.001) compared to hepatectomy alone. There were significant concerns regarding the risk of bias in most of the included studies. Overall, adjuvant TACE may be associated with an oncologic benefit in select HCC patients. However, the applicability of these findings may be limited to Eastern Asian populations, due to the geographically restricted sample. High-quality multinational RCTs, as well as predictive tools to optimize patient selection, are necessary before adjuvant TACE can be routinely implemented into standard practice.

AbstractThe possible effect of probiotic interventions on immunological markers in athletes is inconclusive. Therefore, to synthesize and quantitatively analyze the existing evidence on this topic, systematic literature searches of online databases PubMed, Scopus, Cochrane Library, and ISI Web of Sciences was carried out up to February 2021 to find all randomized controlled trials (RCTs) concerning the immunological effects of probiotics in athletes. In the random-effects model, weighted mean difference (WMD) and 95% confidence interval (CI) explained the net effect. The authors assessed the likelihood of publication bias via Egger’s and Begg’s statistics. A total of 13 RCTs (836 participants) were retrieved. Probiotic consumption reduced lymphocyte T cytotoxic count significantly (WMD=−0.08 cells×109/L; 95% CI: −0.15 to −0.01; p=0.022) with evidence of moderate heterogeneity (I 2=59.1%, p=0.044) and monocyte count when intervention duration was ≤ 4 weeks (WMD=−0.08 cells×109/L; 95% CI: −0.16 to −0.001; I 2=0.0%). Furthermore, leukocyte count was significantly elevated (WMD=0.48 cells×109/L; 95% CI: 0.02 to 0.93; I 2=0.0%) when multi-strain probiotics were used. Probiotic supplements may improve immunological markers, including lymphocyte T cytotoxic, monocyte, and leukocyte in athletes. Further randomized controlled trials using diverse strains of probiotics and consistent outcome measures are necessary to allow for evidence-based recommendations.

Background. A substantial proportion of patients undergoing colorectal surgery receive a temporary stoma, and the timing for stoma closure remains unclear. The aim of this study was to evaluate the safety and feasibility of early stoma closure (ESC) compared with routine stoma closure (RSC) after colorectal surgery. Methods. We comprehensively searched PubMed, Embase, and the Cochrane Library for randomized controlled trials that compared ESC and RSC after colorectal surgery. Results. A total of 7 randomized controlled trials with 814 enrolled patients were identified for this meta-analysis. There were no significant differences between the ESC and RSC groups regarding the complications of stoma closure (26.8% and 16.6%, respectively; odds ratio [OR]: 1.30; 95% confidence interval [CI]: 0.89-1.90; P = .17). A subgroup analysis was conducted by Clavien-Dindo grade of complication, and no significant difference was observed in any subgroup ( P > .05). However, the ESC group had a significantly higher risk of wound complications than the RSC group (17.6% and 7.8%, respectively; OR: 2.61; 95% CI: 1.43-4.76; P = .002), and the RSC group had more cases of small bowel obstruction than the ESC group (3.1% and 8.4%, respectively; OR: 0.37; 95% CI: 0.15-0.87; P = .02). Conclusions. ESC is a safe and effective therapeutic approach in patients who have undergone colorectal surgery; it is associated with a reduced risk of bowel obstruction but a higher risk of wound complications.

Background: Vitamin D levels have been reported to be associated with COVID-19 susceptibility, severity and mortality events.. We performed a meta-analysis of randomized controlled trials (RCTs) to evaluate the use of vitamin D intervention on COVID-19 outcomes. Methods: Literature search was conducted using PubMed, Cochrane library, and ClinicalTrials.gov databases (latest search on August 5, 2021). We included RCTs reporting the use of vitamin D intervention to control/placebo group in COVID-19. Two independent researchers did literature search, abstracted data, and the risk of bias assessment. Results: A total of 6 RCTs with 551 COVID-19 patients were included. The overall collective evidence pooling all the outcomes across all RCTs indicated the beneficial use of vitamin D intervention in COVID-19 (relative risk, RR = 0.60, 95% CI 0.40 to 0.92, Z=2.33, p=0.02, I2 = 48%). However, no statistical significance was observed for individual outcomes of ICU care (RR = 0.11, 95% CI 0.15 to 1.30, Z=1.48, p=0.14, I2 = 66%) and mortality (RR = 0.78, 95% CI 0.25 to 2.40, Z=0.66, p=0.02, I2 = 33%), though decreased rates were noted. The rates of RT-CR positivity was significantly decreased in the intervention group as compared to the non-vitamin D groups (RR = 0.46, 95% CI 0.24 to 0.89, Z=2.31, p=0.02, I2 = 0%). Conclusion: COVID-19 patients supplemented with vitamin D are more likely to demonstrate fewer rates of ICU admission, mortality events and RT-PCR positivity. However, no statistical significance has been achieved for individual outcomes of ICU and deaths. More RCTs and completion of ongoing trials largely needed to precisely establish the association between vitamin D use and COVID-19.

Abstract BACKGROUND: Poly(ADP–ribose) polymerase (PARP) inhibitors are new class of drugs that are currently being studied in several malignancies. However, datas about the efficacy and safety of the PARP inhibitors are limited. Therefore, we conducted a meta-analysis of randomized controlled trials (RCT) in patients with breast cancer.METHODS: Pubmed/Medline, Embase, Cochrane Library, and abstracts presented at the annual meeting of the American Society of Clinical Oncology (ASCO) were searched for articles published from 2000 to June 2018.Summary incidences and the RR, HR with 95% confidence intervals, were calculated by using a random-effects or fixed-effects model.RESULTS: The summary HR indicated PARPi was not associated with OS (HR=0.83, 95%CI 0.66–1.06, Z=1.49, P=0.14), while it could significantly improve PFS ande time to deterioration (TTD) of global health status/quality of life(GHS/QoL) as compared with traditional standard therapy, the HR was 0.60(95%CI 0.50-0.72; Z=5.52, P<0.00001) and 0.4 (95%CI 0.29–0.54,z=5.80 ,p=0.000),respectively.The RR of grade 3 or more anemia ,fatigue and headache was 3.02 (95% CI, 0.69–13.17;p = 0.14,,I2=90%),0.77 (95%CI, 0.34–1.73;p=0.52,I2=7%) and 1.13 (95% CI,0.30–4.18;p=0.86,I2=0%),respectively.CONCLUSION: The findings of this meta-analysis showed that PARPi has no significant effect on OS, while it could significantly improve in PFS and TTD of GHS/QoL for patients with advanced or metastatic breast cancer.Furthermore,our findings also demonstrated that the PARPi treatment is connected with an increased risk of grade 3 or more anemia adverse events.
