Background: Human bocavirus (HBoV) figures as an increased risk factor of respiratory and gastrointestinal tract infections among children. A great deal of data is available to support the pathogenic role of HBoV in acute respiratory diseases. However, the association between HBoV infection and gastroenteritis remains controversial due to the ambiguous results. The present work aims to clarify the role of HBoV as a cause of gastroenteritis in children. Methodology/Principal findings: A systematic search of the literature was carried out from 1 January 2016 to 29 August 2021 in Embase, PubMed, Scopus, Web of Science, and the Chinese bibliographic database of biomedicine (CBM). Data from included studies were analyzed by use of a random-effects model. The pooled estimates of HBoV prevalence among all cases of gastroenteritis were generated and stratified by potential confounders. The pooled odds ratio (OR) and 95% confidence interval (CI) were computed for HBoV infection in relation to the risk of gastroenteritis. The overall prevalence of HBoV in children with gastroenteritis (9.1%, 95% CI: 6.7-11.8%) was considerably higher than that detected in children without gastroenteritis (4.0%, 95% CI: 1.1-8.5%). HBoV prevalence tended to be higher in cases of gastroenteritis under five years of age (12.1%, 95% CI: 6.8-18.7%). The highest frequency of HBoV was found in Egypt (57.8%, 95% CI: 47.7-67.6%). The predominant genotypes of HBoV circulating in children with gastroenteritis were genotype 1 (HBoV1, 3.8%, 95% CI: 2.7-5.2%) and genotype 2 (HBoV2, 2.4%, 95% CI: 1.3-3.7%). HBoV infection was significantly associated with an increased risk of gastroenteritis in children (OR 1.620, 95% CI: 1.023-2.566). Conclusion: The HBoV prevalence in pediatric cases of gastroenteritis is higher than that in children without gastroenteritis, demonstrating an increasing global burden of gastroenteritis in children caused by HBoV infection. Targeted intervention to reduce the HBoV burden should be established.

Background. The role of RAD51 gene polymorphisms with the development of head and neck cancer (HNC) and esophageal cancer (EC) remains controversial. This meta-analysis was conducted to evaluate the correlation between the RAD51 polymorphisms and these two cancers quantitatively. Methods. Databases of PubMed, Web of Science, and Embase were used to search relevant papers prior to August 17, 2019. STATA 11.0 was performed to observe the correlation. Results. Ten relevant papers were enrolled in our analysis. Overall, a significant correlation was observed between the rs1801320 polymorphism and the increased risk of these two cancers (OR=1.32, 95%CI=1.03‐1.71 for C vs. G; OR=1.50, 95%CI=1.03‐2.19 for CG vs. GG; and OR=1.44, 95%CI=1.05‐1.99 for CC+CG vs. GG). In subgroup analyses, an increased risk was found for EC (OR=2.07, 95%CI=1.01‐4.25 for C vs. G; OR=2.08, 95%CI=1.17‐3.71 for CC vs. GG; and OR=1.78, 95%CI=1.00‐3.15 for CC vs. CG+GG), but not for HNC. Moreover, our analysis revealed that no statistical evidence of correlation was discovered between the polymorphism of rs1801321 and the increased risk of HNC. However, stratified analysis based on ethnicity suggested that rs1801321 polymorphism was related to the decreased risk of HNC among Caucasians (OR=0.82, 95%CI=0.72‐0.95 for T vs. G). Conclusions. rs1801320 polymorphism was strongly associated with the risk of these two associated cancers, especially with esophageal cancer. Moreover, our results revealed that rs1801321 polymorphism was correlated to the decreased risk of HNC among Caucasians.

Abstract Objectives Air pollution can lead to many cardiovascular and respiratory diseases, but the impact of air pollution on pulmonary embolism is still uncertain. We conducted a meta-analysis to assess the relationship between air pollution and pulmonary embolism. Content We searched PubMed, EMBASE, Web of Science, and the Cochran Library for citations on air pollutants (carbon monoxide, sulfur dioxide, nitrogen dioxide, ozone and particulate matter) and pulmonary embolism. A total of nine citations met the inclusion criteria. There is no evidence of bias. CO, SO2, PM10 and PM2.5 had no significant effect on the occurrence of pulmonary embolism. NO2 and O3 can increase the risk of pulmonary embolism to a small extent. Summary This meta-analysis suggests that some air pollutants are associated with an increased risk of pulmonary embolism. Outlook Reducing air pollution and improving air quality can effectively reduce the risk of pulmonary embolism.

Background:Studies pertaining to association of GSTM1 and GSTT1 null genotypes with risk of T2DM and its complications were often inconclusive, thus spurring the present study.Methods:Meta-analysis of 25 studies for evaluating the role of GSTM1/GSTT1 null polymorphisms in determining the risk for T2DM and 17 studies for evaluating the role of GSTM1/GSTT1 null polymorphisms in development of T2DM related complications were conducted.Results:Our study revealed an association between GSTM1 and GSTT1 null polymorphism with T2DM (GSTM1; OR=1.37;95% CI =1.10-1.70 and GSTT1; OR=1.29;95% CI =1.04-1.61) with an amplified risk of 2.02 fold for combined GSTM1-GSTT1 null genotypes. Furthermore, the GSTT1 null (OR=1.56;95%CI=1.38-1.77) and combined GSTM1-GSTT1 null genotypes (OR=1.91;95%CI=1.25- 2.94) increased the risk for development of T2DM related complications, but not the GSTM1 null genotype. Stratified analyses based on ethnicity revealed GSTM1 and GSTT1 null genotypes increase the risk for T2DM in both Caucasians and Asians, with Asians showing much higher risk of T2DM complications than Caucasians for the same. </P><P> Discussion: GSTM1, GSTT1 and combined GSTM1-GSTT1 null polymorphism may be associated with increased risk for T2DM; while GSTT1 and combined GSTM1-GSTT1 null polymorphism may increase the risk of subsequent development of T2DM complications with Asian population carrying an amplified risk for the polymorphism.Conclusion:Thus GSTM1 and GSTT1 null genotypes increases the risk for Type 2 diabetes mellitus alone, in combination or with regards to ethnicity.

Abstract Background and aims The association between smoking and inflammatory bowel disease (IBD) relies on old meta-analyses including exclusively non-Jewish White populations. Uncertainty persists regarding the role of smoking in other ethnicities. Methods We systematically searched Medline/PubMed, Embase and Scopus for studies examining tobacco smoking and the risk of developing IBD, i.e., Crohn’s disease (CD) or ulcerative colitis (UC). Two authors independently extracted study data and assessed each study’s risk-of-bias. We examined heterogeneity and small-study effect, and calculated summary estimates using random-effects models. Stratified analyses and meta-regression were employed to study the association between study-level characteristics and effect estimates. The strength of epidemiological evidence was assessed through prespecified criteria. Results We synthesized 57 studies examining the smoking-related risk of developing CD and UC. Non-Jewish White smokers were at increased risk of CD (29 studies; RR: 1.95, 95% CI: 1.69‒2.24; moderate evidence). No association was observed in Asian, Jewish and Latin-American populations (11 studies; RR: 0.97; 95% CI: 0.83–1.13), with no evidence of heterogeneity across these ethnicities. Smokers were at reduced risk of UC (51 studies; RR: 0.55, 95% CI: 0.48–0.64; weak evidence) irrespectively of ethnicity; however, cohort studies, large studies and those recently published showed attenuated associations. Conclusions This meta-analysis did not identify any increased risk of CD in smokers in ethnicities other than non-Jewish Whites, and confirmed the protective effect of smoking on UC occurrence. Future research should characterize the genetic background of CD patients across different ethnicities to improve our understanding on the role of smoking in CD pathogenesis.

The Impact

The microbiome of the urinary tract plays a significant role in maintaining health through the impact on bladder homeostasis. Urobiome is of great importance in maintaining the urothelial integrity and preventing urinary tract infection (UTI), as well as promoting local immune function. Dysbiosis in this area has been linked to an increased risk of UTIs, nephrolithiasis, and dysfunction of the lower urinary tract. However, the number of studies in the pediatric population is limited, thus the characteristic of the urobiome in children, its role in a child’s health, and pediatric urologic diseases are not completely understood. This review aims to characterize the healthy urobiome in children, the role of dysbiosis in urinary tract infection, and to summarize the strategies to modification and reshape disease-prone microbiomes in pediatric patients with recurrent urinary tract infections.

RationaleSevere fetal malnutrition has been related to an increased risk of respiratory diseases later in life, but evidence for the association of a suboptimal diet during pregnancy with respiratory outcomes in childhood is conflicting. We aimed to examine whether a pro-inflammatory or low-quality maternal diet during pregnancy was associated with child's respiratory health.MethodsWe performed an individual participant meta-analysis among 18 326 mother-child pairs from seven European birth cohorts. Maternal pro-inflammatory and low-quality diet were estimated by energy-adjusted Dietary Inflammatory Index (E-DIITM) and Dietary Approaches to Stop Hypertension (DASH) scores. Preschool wheezing and school-age asthma were measured by questionnaires and lung function by spirometry.ResultsAfter adjustment for lifestyle and sociodemographic factors, we observed that a higher maternal E-DII score (a more pro-inflammatory diet) during pregnancy was associated only with a lower FVC in children (Z-score difference (95% confidence interval (CI)): −0.05 (−0.08, −0.02), per IQR increase). No linear associations of the maternal E-DII or DASH score with child's wheezing or asthma were observed. When exploratively examining the extremes, a very low DASH score (<10th percentile) (a very low dietary quality) was associated with an increased risk of preschool wheezing and a low FEV1/FVC (z-score <−1.64) (OR (95% CI) 1.20 (1.06, 1.36), 1.40 (1.06, 1.85), compared to ≥10th percentile), with corresponding population attributable risk fractions of 1.7% and 3.3%.ConclusionMain results from this individual participant data meta-analysis do not support the hypothesis that maternal pro-inflammatory or low-quality diet in pregnancy are related to respiratory diseases in childhood.

Abstract Background We performed this meta-analysis to elucidate whether the expression of PlncRNA-1 might serve as an effective prognostic marker for various cancers. Methods We conducted a database search of PubMed, ScienceDirect, Embase, Web of Science and CNKI database (up to Oct 31, 2019). The pooled hazard ratio (HR), odds ratio (OR) and 95% confidence interval (CI) were used to estimate the strength of the relationship between PlncRNA-1 expression and the clinical prognosis of cancer patients. Results The results showed that elevated PlncRNA-1 expression predicted a poor OS with pooled HRs of 1.43 (95% CI: 1.25-1.63, I 2 =63.1%, P=0.004). Likewise, we found that advanced tumour stages were associated with upregulated PlncRNA-1 expression in various cancer types (III–IV vs I–II: OR=2.79, 95% CI: 1.76-4.41, I 2 =0%, P=0.822),patients with high PlncRNA-1 expression might have an increased risk of large tumours (OR=2.03, 95% CI: 1.31-3.14, I 2 =67.1%, P=0.028). Conclusions PlncRNA-1 might be used as a prognostic biomarker and as a tool for the early detection of various tumours.

Background Interleukin-12 (IL-12) is considered to be a risk factor for cancer; however, its role in hepatocellular carcinoma (HCC) remains unknown. This study aimed to explore the impacts of the IL-12 rs3212227 and rs568408 gene polymorphisms on HCC. Methods We searched PubMed, Embase, Web of Science, and Chinese Knowledge Infrastructure databases for studies on the associations between HCC and IL-12 rs568408 and rs3212227 polymorphisms published prior to 1 May 2020. The effects of the polymorphisms on HCC susceptibility were presented as odds ratios (ORs) and associated 95% confidence intervals. Results Seven studies were ultimately included, including 2375 cases and 3445 controls. The rs3212227 polymorphism was significantly associated with the risk of HCC in both the dominant model (CC+AC vs. AA, OR=1.22) and the allele model (C vs. A, OR=1.12). Combined analysis of rs568408 yielded a significant relative risk for HCC in the dominant (AA+AG vs. GG, OR=1.13), recessive (AA vs. AG+GG, OR=1.72), allele (A vs. G, OR=1.29), heterozygote (AG vs. GG, OR=1.27), and homozygote models (AA vs. GG, OR 1.17). Conclusion The IL-12 rs3212227 and rs568408 gene polymorphisms are associated with an increased risk of HCC.

Recently extensive focus has been concentrated on the role of miRNAs in the initiation and progression of cardio-cerebrovascular diseases (CCDs) which constitute a range of conditions including cardiovascular diseases (CVDs, especially coronary artery disease (CAD)), congenital heart disease (CHD) and cerebrovascular diseases (CBVDs, especially the ischemic stroke (IS)). An increasing number of studies are evaluating the association between different miRNA polymorphisms and risk of CCDs, but results have been inconclusive. This study represents a comprehensive systematic review and meta-analysis of the association between miRNA polymorphisms and risk of CCDs. PubMed, Embase, Scopus, and Web of Science were queried to identify eligible articles. Odds ratios and 95% confidence intervals were used to assess the association of miRNA polymorphisms with CCD susceptibility. A total of 51 eligible articles evaluating the association of 31 miRNA polymorphisms were identified. Meta-analysis was performed for six miRNA polymorphisms. miR-146a rs2910164 (30 studies: 13,186 cases/14,497 controls), miR-149 rs2292832 (Nine studies: 4116 cases/3511 controls), miR-149 rs71428439 (Three studies: 1556 cases/1567 controls), miR-196a2 rs11614913 (20 studies: 10,144 cases/10,433 controls), miR-218 rs11134527 (Three studies: 2,322 cases/2,754 controls) were not associated with overall CCD. miR-499 rs3746444 was associated with CCD (20 studies: 9564 cases/8876 controls). In the subgroups, rs2910164 and rs3746444 were only associated with CVDs, especially CAD. In conclusion, the results support the existence of a role for miR-146a rs2910164 and miR-499 rs3746444 in determining susceptibility to CCDs, especially CAD.

Objective To assess whether febuxostat use increases the risk of developing cardiovascular events, death from cardiac-cause and all-cause mortalities. Methods The relevant literature was searched in several databases including the MEDLINE (PubMed, 1 Jan. 1966–29 Feb. 2020), Web of science, EMBASE (1 Jan. 1974–29 Feb. 2020), ClinicalTrials.gov and Cochrane Central Register for Controlled Trials. Manual searches for references cited in the original studies and relevant review articles were also performed. All studies included in this metanalysis were published in English. Results In the end, 20 studies that met our inclusion criteria were included in this meta-analysis. Use of febuxostat was found not to be associated with an increased risk of all-cause mortality (RR = 0.87, 95% CI 0.57–1.32, P =0.507). Also, there was no association between febuxostat use and mortalities arising from cardiovascular diseases (CVD) (RR = 0.84, 95% CI 0.49–1.45, P=0.528). The RR also revealed that febuxostat use was not associated with CVD events (RR = 0.98, 95% CI 0.83–1.16, P =0.827). Furthermore, the likelihood of occurrence of CVD events was found not to be dependent on febuxostat dose (RR = 1.04, 95% CI 0.84–1.30, P =0.723). Conclusion Febuxostat use is not associated with increased risks of all-cause mortality, death from CVD or CVD events. Accordingly, it is a safe drug for the treatment of gout.
