SUMMARY BACKGROUND An association between increased serum ferritin levels and acute myocardial infarction (AMI) remains controversial. The purpose of this meta-analysis is to confirm the association between increased serum ferritin levels and AMI. METHODS We searched PubMed and China National Knowledge Infrastructure (CNKI) for relevant articles that assessed the association between serum ferritin and acute myocardial infarction using terms that included serum ferritin and acute myocardial infarction up to February 13, 2019. RESULTS A total of 11 studies were identified for analysis. All pooled analysis was based on a random-effects models. The variance was exhibited using a forest plot, and the heterogeneity among studies was examined using the I2 index, the publication bias was evaluated using a funnel plot. The pooled standard mean difference of ferritin levels between AMI and controls was 0.78 (95%CI,0.68-0.88). CONCLUSION The results of this meta-analysis demonstrate that serum ferritin in acute myocardial infarction patients is higher than that of healthy controls.

The Relationship

Abstract Background Published studies have shown contradictory results regarding the relationship between somatometric parameters and varicoceles. We performed a systematic review and meta-analysis to investigate the possible effects of age, height, weight, and body mass index (BMI) on the presence and severity of varicoceles. Methods Databases including EMBASE, MEDLINE, PubMed, Cochrane Library, China National Knowledge Infrastructure (CNKI), Web of Science, and Google Scholar were systematically searched to identify relevant articles published up to March 2020. Two researchers independently identified eligible articles and extracted data. Cochran’s Q statistic and I2 statistics were used to assess heterogeneity. Meta-analysis was performed using StataSE 12.0 software (StataCorp LP, USA). Random-effects models were used to obtain the weighted mean differences (WMDs) and 95% confidence intervals (CIs). Publication bias was assessed using Begg’s funnel plot and Egger’s regression test. Results The search strategy produced 272 articles, of which 18 articles were eligible according to the inclusion/exclusion criteria. A total of 56,325 patients with varicocele and 1,334,694 patients without varicocele were included in the meta-analysis to evaluate the effect of somatometric parameters on the presence and severity of varicocele. The overall results demonstrated that the presence of varicoceles was significantly associated with height (WMD = 1.41, 95% CI = 1.07 to 1.74, P < 0.001) and inversely correlated with BMI (WMD = − 1.35, 95% CI = -1.67 to − 1.03, P < 0.001) but not with age (WMD = -0.93, 95% CI = -2.19 to 0.33, P = 0.149) or weight (WMD = 0.24, 95% CI = -2.24 to 2.72, P = 0.850). The severity of varicocele was inversely correlated with increased BMI but not with age. Conclusion The presence of varicoceles was significantly associated with height and inversely correlated with BMI.

Background: The apolipoprotein E epsilon 4 (APOE4) is the strongest genetic risk factor for sporadic Alzheimer’s disease (AD). Its carriage percentage in non-demented population varies across geographic regions and ethnic groups. Objective: To estimate the proportion of APOE4 (2/4, 3/4, or 4/4) carriers in non-demented community-dwellers. Methods: PubMed, EMBASE, and China National Knowledge Infrastructure were searched from inception to April 20, 2020. Community-based studies that reported APOE polymorphisms with a sample of≥500 non-demented participants were included. Random-effects models were used to pool the results. Meta-regression and subgroup analyses were performed to test the source of heterogeneity and stratified effects. Age-standardized pooled proportion estimates (ASPPE) were calculated by direct standardization method. Results: A total of 121 studies were included, with a pooled sample of  389,000 community-dwellers from 38 countries. The global average proportion of APOE4 carriers was 23.9% (age-standardized proportion: 26.3%; 2.1% for APOE4/4, 20.6% for APOE3/4 and 2.3% for APOE2/4), and varied significantly with geographical regions (from 19.3% to 30.0%) and ethnic groups (from 19.1% to 37.5%). The proportion was highest in Africa, followed by Europe, North America, Oceania, and lowest in South America and Asia (p <  0.0001). With respect to ethnicity, it was highest in Africans, followed by Caucasians, and was lowest in Hispanics/Latinos and Chinese (p <  0.0001). Conclusion: APOE4 carriers are common in communities, especially in Africans and Caucasians. Developing precision medicine strategies in this specific high-risk population is highly warranted in the future.

Objective This meta-analysis aimed to determine the associations between the rs3761547, rs3761548, and rs3761549 single-nucleotide polymorphisms (SNPs) of the forkhead box P3 ( FOXP3) gene and susceptibility to Graves’ disease (GD). Methods Case–control studies with information on the associations between the rs3761547, rs3761548, and rs3761549 FOXP3 SNPs and GD published before 01 May 2020 were identified in the PubMed, Embase, Web of Science, and China National Knowledge Infrastructure databases. Data from the studies were analyzed using RevMan version 5.3. Results Seven independent case–control studies including 4051 GD patients and 4569 controls were included in the meta-analysis. The overall pooled analysis indicated that FOXP3/rs3761548 and FOXP3/rs3761549 polymorphisms were significantly associated with GD susceptibility (rs3761548: A vs. C, odds ratio [OR] = 1.32, 95% confidence interval [CI] 1.05–1.67; rs3761549: TT vs. CC, OR = 1.98, 95%CI 1.49–2.65; (TT + TC) vs. CC, OR = 1.44, 95%CI 1.11–1.88). In contrast, the FOXP3/rs3761547 polymorphism was not associated with GD susceptibility. Subgroup analysis according to ethnicity showed that rs3761548 was associated with GD in Asians but not in Caucasians, whereas rs3761549 was associated in both Asians and Caucasians. Conclusion This meta-analysis demonstrated that FOXP3/rs3761548 and FOXP3/rs3761549 SNPs were significantly associated with susceptibility to GD, at least in Asian populations.

Abstract Background Community-acquired pneumonia (CAP) is a respiratory disease that is responsible for an estimated 3.5 million worldwide deaths annually. In the last few years, it has been hypothesized that CAP is implicated in the development of diseases in other systems such as renal and cardiovascular. Until this moment, multiple studies evaluating incidence of acute myocardial infarction (AMI) in patients with CAP exist, but data are still unclear. Our objective was to summarize several studies available regarding incidence of Acute Myocardial Infarction (AMI) in patients with CAP and to compare such value with the incidence of AMI in the general population. Methods We conducted a systematic review of articles published between January 1980 and January 2019 in the PubMed and PubMed Central databases. Studies describing the incidence of AMI in patients with CAP were included. We extracted their diagnostic criteria for CAP and AMI, and their AMI follow-up periods. In addition to this, we calculated cumulative incidence of AMI in patients with CAP and compared such value with the general population. Results 1841 studies were identified (Figure 1), of which 10 studies were included in our review (Figure 2). From a forest plot-random effects model, the cumulative incidence of AMI among patients hospitalized due to CAP was 2,440 per 100,000 (95% CI: 1,780; 3,320) (Figure 3). Using the age-adjusted incidence of 649 cases of CAP per 100,000 adults described by Ramirez et al., we estimated that 16 per 100,000 adults will have an AMI associated with CAP (95% CI: 12;22) per year in the US Moreover, Yeh et al. found that the incidence of AMI in the general population was 208 per 100,000 people, comparing this value, to the values obtained in our meta-analysis of 2,440 acute myocardial infarctions by 100, 000 people, we can infer that adult patients hospitalized due to CAP have an 11.7-fold increase from the general population for risk of MI. Conclusion A higher risk of AMI was observed among adults hospitalized with CAP compared with the general population. Results must be carefully analyzed given the heterogeneity of the studies. At a clinical level, this increase in AMI incidence in patients with CAP should be taken into account in order to give the best therapeutic management to such patients.

Background: This review aims to estimate the prevalence of the neglect of 3- to 6-year-old children in China. Method: We systematically searched both English- (Web of Science, PsychINFO, PubMed, and Cochrane Library) and Chinese-language databases (China National Knowledge Infrastructure, Wanfang, Weipu, and Biomedical Database). We extracted data related to the prevalence of early childhood neglect and its subtypes and pooled it using random effects models. Findings: We included 21 eligible studies, with a total of 35,175 3- to 6-year-old children, in the analyses. The pooled neglect prevalence was 32.1% at a 95% confidence interval (95% CI [27.0%, 37.2%]). The prevalence of physical, emotional, educational, security, and medical neglect was 15.2% (95% CI [11.9%, 18.5%]), 15.2% (95% CI [10.7%, 19.6%]), 10.4% (95% CI [7.4%, 13.4%]), 13.8% (95% CI [9.9%, 17.8%]), and 11.5% (95% CI [8.1%, 14.9%]), respectively. No gender or location differences were found to affect early childhood neglect or its subtypes. Interpretation: Our results revealed a high prevalence of early childhood neglect—including all its subtypes—among 3- to 6-year-old children in China. Improved child policies and prevention programs tailored to preschool children are needed to protect the well-being of younger children.

Objective: Several studies suggested that Qigong exercise (QE) can relieve fatigue in patients diagnosed with various diseases. Our review aimed to evaluate the efficacy of QE for alleviating fatigue.Methods: A related literature search was performed in the PubMed, Web of Science, Embase, Cochrane Library, China Biology Medicine disc (CBM), China National Knowledge Infrastructure (CNKI), Wanfang, and VIP data bases from inception to November 2020. Information on fatigue, malaise, tiredness, and Qigong research data was collected.Results: Sixteen randomized controlled trials (RCTs) were reported in patients with cancer (n = 4), chronic fatigue syndrome (n = 2), and other diseases (n = 10). The QE groups showed significant improvements in total fatigue intensity [15 RCTs, p &lt; 0.00001; standard mean difference (SMD) −0.69 (−0.95 to −0.44)]. The QE groups did not show significant improvement in quality of life [4 RCTs, p = 0.08; SMD 0.53 (−0.07 to 1.14)]. The statistically significant difference of the subgroup analyses (different primary diseases, QE types, and study quality) also remained unchanged.Conclusion: The findings of this meta-analysis indicate that QE may be beneficial for improving fatigue in patients diagnosed with various diseases. Considering the limitations of the study, we draw a very cautious conclusion regarding the resulting estimate of the effect. Further studies are warranted to better understand the benefits of QE in primary medical care.

Abstract Background: Coronavirus disease 2019 (COVID-19) is a novel infectious disease, with significant morbidity and mortality. This meta-analysis is to evaluate the prevalence of disseminated intravascular coagulation (DIC) in COVID-19 patients and to determine the association of DIC with the severity and prognosis of COVID-19.Methods: We searched the PubMed, EMBASE, and China National Knowledge Infrastructure (CNKI) database until August 12, 2020. The meta-analysis was performed using Stata 16.0 software.Results: 15 studies were included in our meta-analysis. The pooled analysis revealed that the incidence of COVID-19 patients developing DIC was 4% (95%: 2%-5%, P<0.001). In addition, DIC was more likely to occur in the death group (Log OR = 2.4, 95% CI: 1.58-3.21, P<0.001) with statistical significance.Conclusions: DIC is associated with the severity and poor prognosis of COVID-19 patients. Therefore, attention should be paid to coagulation dysfunction in COVID-19 patients. Monitoring of coagulation indicators may improve the prognosis of COVID-19 inpatients.

Background and aims: Hyperbaric oxygenation therapy has been used in the treatment of ulcerative colitis in the past few years. However, its efficacy still remains unclear. The aim of the study was to investigate the efficacy of hyperbaric oxygen combination therapy in patients with ulcerative colitis. Methods: We conducted a comprehensive study search up to September 2020, from the online databases Embase, PubMed, Cochrane Library, China National Knowledge Infrastructure, WanFang and VIP. Results: Thirteen studies comprising 780 patients were included. We found that compared with conventional therapy, hyperbaric oxygen combination therapy was superior in reaching clinical remission [risk ratio (RR)=1.62; 95% confidence interval (CI) 1.42 to 1.84; p < 0.001] and clinical response (RR=1.29; 95% CI 1.21 to 1.38; p < 0.001), with lower disease activity scores [standard mean difference (SMD)= −1.19; 95%CI −1.74 to −0.65; p < 0.001]. An obvious reduction of serum levels of tumor necrosis factor-α (SMD= −1.96; 95%CI −2.50 to −1.41; p < 0.001) and interleukin (IL)-6 (SMD= −2.49; 95% CI −2.84 to −2.15; p < 0.001), and elevation of IL-10 level (SMD=2.40; 95% CI 0.68 to 4.12; p = 0.006) were also observed. Conclusion: Hyperbaric oxygen combination therapy was effective in patients with ulcerative colitis, and has potential as a complementary method for its treatment.
