Warfarin Maintenance Dose

This meta-analysis was conducted to analyze the effect of NQO1 polymorphism on the warfarin maintenance dosage. Using strict inclusion and exclusion criteria, we searched PubMed, EMBASE, and the Cochrane Library for eligible studies published prior to July 7, 2021. The required data were extracted, and experts were consulted when necessary. Review Manager Version 5.4 software was used to analyze the relationship between NQO1 polymorphisms and the warfarin maintenance dosage. Four articles involving 757 patients were included in the meta-analysis. Patients who were NQO1 rs10517 G carriers (AG carriers or GG carriers) required a 48% higher warfarin maintenance dose than those who were AA carriers. Patients with NQO1 rs1800566 CT carriers required a 13% higher warfarin dose than those who were CC carriers, with no associations observed with the other comparisons of the NQO1 rs1800566 genotypes. However, the results obtained by comparing the NQO1 rs1800566 genotypes require confirmation, as significant changes in the results were found in sensitivity analyses. Our meta-analysis suggests that the NQO1 rs10517and NQO1 rs1800566 variant statuses affect the required warfarin maintenance dose.

Objective To explore the impact of appendectomy history on emergence of Parkinson’s disease (PD). Background Although there are several studies to investigate the relationship between appendectomy history and emergence of PD, the results are still controversial. Methods We performed a comprehensive electronic search of the literature (the Cochrane Library, PubMed, and the Web of Science) up to April 2020 to identify studies that had employed databases allowing comparison of emergence of PD between patients with and those without appendectomy history. To integrate the impact of appendectomy history on emergence of PD, a meta-analysis was performed using random-effects models to calculate the risk ratio (RR) and 95% confidence interval (CI) for the selected studies, and heterogeneity was analyzed using I2 statistics. Results Four studies involving a total of 6 080 710 patients were included in this meta-analysis. Among 1 470 613 patients with appendectomy history, 1845 (.13%) had emergences of PD during the observation period, whereas among 4 610 097 patients without appendectomy history, 6743 (.15%) had emergences of PD during the observation period. These results revealed that patients with appendectomy history and without appendectomy had almost the same emergence of PD (RR, 1.02; 95% CI, .87-1.20; P = .83; I2 = 87%). Conclusion This meta-analysis has demonstrated that there was no significant difference in emergence of PD between patients with and those without appendectomy history.

<b><i>Introduction:</i></b> The aim of this article was to investigate the relationship between statins and the risk of different stages or grades of prostate cancer. <b><i>Methods:</i></b> A comprehensive literature search was performed for articles published until December 18, 2020, on the PubMed, Embase, and the Cochrane Library databases. The pooled relative risk (RR) and 95% confidence interval (CI) were then analyzed using the STATA.16.0 software. <b><i>Results:</i></b> A total of 588,055 patients from 14 studies were included in the analysis. We found that the use of statins expressed a significant correlation with a lower risk of advanced prostate cancer (RR = 0.81, 95% CI: 0.73–0.91; RR = 0.86, 95% CI: 0.75–0.99, respectively). However, no evidence suggested that the use of statins was beneficial for the prevention of localized prostate cancer incidence. Similarly, the pooled results also revealed no association between the use of statins and the risk of high-grade and low-grade prostate cancer. <b><i>Conclusion:</i></b> It has been found that the use of statins is associated with a lower risk of advanced prostate cancer but was not related to the risk of localized, low-grade, or high-grade prostate cancer.

Recently, numerous studies indicate that H19 plays a key role in tumorigenesis, but the results have been disputed, especially in the aspects of tumor progression and metastasis. Therefore, we performed this meta-analysis to systematically summarize the relationship between H19 and cancers. We searched PubMed, the Cochrane Library, CNKI, and Chinese Wan Fang to identify eligible studies. Odds ratios and 95% confidence intervals were calculated to assess the effect size. A total of 13 studies were enrolled in this meta-analysis, which was performed by Revman5.3 and Stata11.0 software. Our meta-analysis showed that the expression of H19 was associated with distant metastasis in nongastrointestinal tumors (OR = 3.85, 95% CI = 1.31–11.36,P=0.01) and, in gastrointestinal tumors (OR = 0.34, 95% CI = 0.15–0.78,P=0.01), lymph node metastasis (OR = 2.04, 95% CI = 1.19–3.48,P=0.009). Moreover, in gastric cancer, H19 expression was significantly related to histological grade (OR = 0.50, 95% CI = 0.29–0.86,P=0.01), TNM stage (OR = 0.19, 95% CI = 0.11–0.33,P<0.01), and tumor invasion depth (OR = 0.11, 95% CI = 0.04–0.27,P<0.01). Therefore, H19 could serve as a potential marker for progression and metastasis evaluation of cancers.

Background. Studies revealed that metabolic factors might contribute substantially to osteoarthritis (OA) pathogenesis. There has been an increasing interest to understand the relationship between knee OA and the metabolic syndrome (MetS). The purpose of this study was to explore the association between metabolic syndrome and knee osteoarthritis using meta-analysis.Methods. Databases, including PUBMED, EMBASE, and the Cochrane Library, were searched to get relevant studies. Data were extracted separately by two authors and pooled odds ratio (OR) with 95% confidence interval (CI) was calculated.Results. The meta-analysis was finished with 8 studies with a total of 3202 cases and 20968 controls finally retrieved from the database search. The crude pooled OR is 2.24 (95% CI = 1.38–3.64). Although there was significant heterogeneity among these studies, which was largely accounted for by a single study, the increase in risk was still significant after exclusion of that study. The pooled adjusted OR remained significant with pooled adjusted OR 1.05 (95% CI = 1.03–1.07,p<0.00001). No publication bias was found in the present meta-analysis.Conclusions. The synthesis of available evidence supports that metabolic syndrome increases the risk for knee osteoarthritis, even after adjustment for many risk factors.

Acne vulgaris is one of the most common skin diseases and genetic relationships have been documented. The aim was to evaluate the association of CYP17 (T-34C) polymorphism related to the risk of acne in a meta-analysis study. The databases (Scopus, Web of Science, PubMed, and Cochrane Library) were searched until September 2018 to check the relationship between acne risk and CYP17 (T-34C) polymorphism and impact of this polymorphism on severity of acne. We used Review Manager 5.3 software to analyze the data using OR and 95% CI to check this relationship. Four studies were included and analyzed in the meta-analysis. The OR in analysis of C versus T in acne patients compared to the healthy controls was 1.42 (P=0.02), in CC vs. TT was 1.54 (P=0.04), in TC vs. TT was 1.46 (P=0.12), in TC + CC vs. TT was 1.55 (P=0.04), and in CC vs. TT + TC was 1.39 (P=0.06). There was no acne risk related to CYP17 (T-34C) in none of genetic models in Caucasian ethnicity, whereas in Asian ethnicity, there was higher acne risk related to CYP17 (T-34C) without heterogeneity. The results of the present meta-analysis showed the presence of C allele and CC genotype of CYP17 polymorphism can be risk factors for acne, mainly in the Asian ethnicity.

Purpose: To compare the efficacy and safety of robotic-assisted simple prostatectomy and open simple prostatectomy for large benign prostatic hyperplasia.Methods: We systematically searched the Cochrane Library, PubMed, Embase, and Science databases for studies published through December 2020. Controlled trials on RASP and OSP for large prostates were included. The meta-analysis was conducted with the Review Manager 5.4 software.Results: A total of seven studies with 3,777 patients were included in the analysis. There were no significant differences in IPSS (WMD, 0.72; 95%CI: −0.31, 1.76; P = 0.17), QoL (WMD, 0.00; 95%CI: −0.39, 0.39; P &gt; 0.99), Qmax (WMD, 1.88; 95% CI: −1.15, 4.91; P = 0.22), or PVR (WMD, −10.48; 95%CI: −25.13, 4.17; P = 0.16) among patients undergoing RASP and OSP. However, compared with patients who underwent OSP, patients who underwent RASP had a shorter LOS (WMD, −2.83; 95%CI: −3.68, −1.98; P &lt; 0.001), less EBL (WMD, −304.68; 95% CI: −432.91, −176.44; P &lt; 0.001), a shorter CT (WMD, −2.61; 95%CI: −3.94, −1.29; P &lt; 0.001), and fewer overall complications (OR, 0.30; 95% CI: 0.16, 0.57; P &lt; 0.001). Nevertheless, RASP was associated with a longer OT (WMD, 59.69, 95% CI: 49.40, 69.98; P &lt; 0.001).Conclusion: The results of the current study demonstrated that RASP provided similar efficacy to those of OSP in the treatment of large prostate, while maintaining better security. Our findings indicate that RASP is a feasible and effective alternative to OSP.

Several studies have indicated that early repolarization (ER) is a risk factor for ventricular tachyarrhythmias (VTAs) in acute myocardial infarction (AMI) patients. The prognostic values of ER detail characteristics except J-point morphology, and inferior leads ER location for VTAs are still unclear. We searched PubMed, Embase, and the Cochrane Library for eligible studies up to March 4, 2019. Studies to investigate the relationship between ER and the incidence of VTAs in AMI patients were extracted. A total of 10 studies with 2,672 participants were included in the analysis. ER significantly predicted the incidence of VTAs (odds ratio [OR] 3.62, 95% confidence intervals [CI] 2.77–4.73), regardless of the type of AMI. The presence of ER before AMI (OR 5.58, 95% CI 3.41 to 9.12) and after AMI (OR 3.02, 95% CI 2.19–4.15) increased the risk of VTAs. The prognostic value of ER for VTAs in the long follow-up (≥30 days) (OR 2.39, 95% CI 1.59–3.59) fell by half compared to the short follow-up duration (<30 days) (OR 4.97, 95% CI 3.48–7.09). Patients with ER displayed a higher risk of developing ventricular fibrillation (VF) (OR 6.94, 95% CI 3.87–12.43) than those without ER. However, neither J-point elevation with OR = 2.48 nor lateral leads’ ER location with OR = 3.83 remarkably increased the risk of VTAs in patients with AMI. ER is significantly associated with increasing risk of VTAs, particularly VF, in AMI patients. This relationship is weaker in the 30-day follow-up and is not reinforced by J-point elevation and lateral leads’ ER location.

Risk Of Preeclampsia

Abstract Preeclampsia is an idiopathic multisystem disorder with partial genetic and immunological etiology. Several studies investigated the association between various single-nucleotide polymorphisms (SNPs) in Fas and Fas ligand (FasL) genes and the risk of preeclampsia. However, they achieved inconsistent results. Therefore, we conducted a meta-analysis by systematically searching the Cochrane Library, PubMed and Embase databases and assessed this association by calculating pooled odds ratios with 95% confidence interval to reach a more trustworthy conclusion. Subgroup analyses by genotype methods and source of controls (SOC) were also conducted. Seven citations containing nine studies were included for four SNPs (Fas -670 A/G, FasL 124A/G, FasL -844C/T, Fas -1377 G/A) in this meta-analysis. Our data suggested the G allele and genotype GG of the Fas -670 A/G polymorphism, GG genotype of the FasL 124A/G polymorphism, and TT genotype of the FasL -844C/T polymorphism increased the risk of preeclampsia. Stratification analyses by genotype methods and SOC also indicated that Fas -670 A/G polymorphism was related to increased risk for preeclampsia. In conclusion, Fas and FasL gene polymorphisms play important roles in the development of preeclampsia. Further well-designed studies in other races are needed to confirm the findings of this meta-analysis.

Background: Aflibercept has been widely used in treating diabetic macular edema (DME). However, the effect of aflibercept in treating DME refractory to bevacizumab or ranibizumab has not been well established. Objective: To assess the therapeutic effect of switching from bevacizumab or ranibizumab to aflibercept in the treatment of refractory DME. Methods: Relevant studies were searched from 3 databases: the Cochrane Library, PubMed, and Web of Science. Data on changes in best-corrected visual acuity (BCVA), central macular thickness (CMT), and adverse events within the follow-up period were collected and pooled using weighted mean differences (WMDs) with corresponding 95% CIs in a random effects model. The between-study heterogeneity was tested using the χ2 test and the I2 statistic, and funnel plots were used to evaluate the publication bias. Results: A total of 11 nonrandomized trials met the inclusion criteria and were included in the meta-analysis. Our studies showed significant improvements in the BCVA (WMD = 100.55; 95% CI = 68.46 to 132.63; P < 0.01) and reduction in CMT (WMD = 0.09; 95% CI = 0.03 to 0.14; P < 0.01) after switching to aflibercept. Although a large amount of heterogeneity was detected in the CMT results among these studies, the sensitivity analyses showed the reliability and stability of our results. Conclusion and Relevance: There were significant improvements in both visual and anatomical outcomes after switching from bevacizumab or ranibizumab to aflibercept, without risk of adverse events. Thus, switching therapy may be a safe and effective treatment for patients with refractory DME.

Background: Respiratory viruses are known to contribute to asthma exacerbations. A meta-analysis of three studies reported no association between coronavirus disease 2019 (COVID-19) mortality and preexisting asthma. This study aimed to investigate the mortality of patients with COVID-19 in relation to preexisting asthma and other allergic diseases associated with changes in respiratory function.Methods: PubMed, Embase, and the Cochrane Library were queried for papers published up to April 9, 2021: (1) population: patients who tested positive for SARS-CoV-2 according to the WHO guidelines; (2) exposure: preexisting asthma or allergic rhinitis; (3) outcomes: mortality, ICU admission, and/or hospitalization; and (4) language: English. For studies that reported adjusted models, the most adjusted model was used for this meta-analysis; otherwise, unadjusted results were used.Results: Twenty-four studies (1,169,441 patients) were included in this meta-analysis. Patients who died of COVID-19 were not more likely to have preexisting asthma (OR = 0.95, 95%CI: 0.78–1.15, P = 0.602; I2 = 63.5%, Pheterogeneity &lt; 0.001). Patients with COVID-19 and admitted to the ICU (OR = 1.17, 95%CI: 0.81–1.68, P = 0.407; I2 = 91.1%, Pheterogeneity = 0.407), or hospitalized (OR = 0.91, 95%CI: 0.76–1.10, P = 0.338; I2 = 79.1%, Pheterogeneity &lt; 0.001) were not more likely to have preexisting asthma. The results for mortality and hospitalization remained non-significant when considering the adjusted and unadjusted models separately. The results from the sensitivity analyses were consistent with the primary analyses, suggesting the robustness of our results.Conclusion: This meta-analysis suggests that the patients who died from COVID-19, were admitted to the ICU, or hospitalized were not more likely to have asthma.
