Cryptosporidium spp., the causative agent of cryptosporidiosis, can infect a variety of hosts. So far, there has been limited information regarding Cryptosporidium spp. infection in yaks (Bos grunniens). Here, we performed the first systematic review and meta-analysis for Cryptosporidium spp. infection in yaks in China. To perform the meta-analysis, five databases (Chinese National Knowledge Infrastructure (CNKI), VIP Chinese journal database, WanFang Data, PubMed, and ScienceDirect) were employed to search for studies related to the prevalence of Cryptosporidium spp. in yaks in China. The total number of samples was 8,212, and the pooled Cryptosporidium spp. prevalence in yaks was estimated to be 10.52% (1192/8012). The prevalence of Cryptosporidium spp. in yaks was 13.54% (1029/5277) and 4.49% (148/2132) in northwestern and southwestern China, respectively. In the sampling year subgroups, the prevalence before 2012 (19.79%; 650/2662) was significantly higher than that after 2012 (6.07%; 437/4476). The prevalence of Cryptosporidium spp. in cold seasons (20.55%; 188/794) was higher than that in warm seasons (4.83%; 41/1228). In the age subgroup, the yaks with age < 12 months had a higher prevalence (19.47%; 231/1761) than that in yaks with age ≥12 months (16.63%; 365/2268). Among 12 Cryptosporidium spp. species/genotypes, the C. bovis had the highest prevalence. Moreover, the effects of geography (latitude, longitude, precipitation, temperature, and altitude) and climate on Cryptosporidium spp. infection in yaks were evaluated. Through analyzing the risk factors correlated with the prevalence of Cryptosporidium spp., we recommend that effective management measures should be formulated according to the differences of different geographical factors, in order to prevent cryptosporidiosis and reduce economic losses in yaks in China.

Eimeria spp. cause the disease coccidiosis, which results in chronic wasting of livestock and can lead to the death of the animal. The disease, common worldwide, has caused huge economic losses to the cattle industry in particular. This is the first systematic review and meta-analysis of the prevalence of bovine Eimeria in China. Our search of five databases including PubMed, ScienceDirect, China National Knowledge Infrastructure (CNKI), Chongqing VIP, and Wan Fang for articles published up to February 29, 2020 on the prevalence of Eimeria in cattle in mainland China yielded 46 articles, in which the prevalence of cattle ranged from 4.6% to 87.5%. The rate of bovine Eimeria infection has been decreasing year by year, from 57.9% before 2000 to 25.0% after 2015, but it is still high. We also analyzed the region, sampling years, detection methods, feeding model, seasons, and species of bovine Eimeria. We recommend that prevention strategies should focus on strengthening detection of Eimeria in calves in the intensive farming model.

Abstract Background: Moxibustion has been used in treating patients with Peripheral Facial Paralysis(PFP), but its effectiveness and safety have not been systematically evaluated. Therefore, the objective of this review is to comprehensively assess the effectiveness and safety of moxibustion for PFP.Methods: We will conduct a systematic document retrieval of databases from inception to March 18, 2021, including Embase, Cochrane Library, Pubmed, Chinese databases SinoMed, Chinese National Knowledge Infrastructure (CNKI), Chinese Scientific Journals Database and Wanfang Data (WF). Reviewers will independently retrieve databases, identify trials, extract data, and evaluate the quality of eligible randomized controlled trials(RCTs). The outcomes will include: the effective rate, the House-Brackmann (H-B) score, Facial Disability Index (FDI), and side effects. The quality of eligible RCT will be assessed by the Cochrane risk-of-bias. Meta-analysis will be processed by the Cochrane Collaboration’s RevMan 5.3.0.Discussion: This review will provide comprehensive evidence of moxibustion for PFP.Systematic review registration: PROSPERO CRD42020207068

ABSTRACT BACKGROUND: There is increasing evidence to show that TNF-α -308G>A polymorphism may be a risk factor for celiac disease, but the results are inconsistent. OBJECTIVE: Thus, we aimed to perform a meta-analysis involving published studies up to January 2019 to elucidate the association. METHODS: To assess the effect of TNF-α -308G>A polymorphism on celiac disease susceptibility, we searched PubMed, ISI Web of Knowledge, Chinese National Knowledge Infrastructure (CNKI) databases to identify eligible studies, without restriction. Summary odds ratios (ORs) and 95% confidence intervals (CIs) were used to evaluate the susceptibility to celiac disease. RESULTS: A total of 11 studies with 1147 cases and 1774 controls were selected for this meta-analysis. The pooled results indicated that TNF-α -308G>A polymorphism was associated with increased risk of celiac disease (A vs G: OR=2.077, 95% CI=1.468-2.939, P=≤0.001; AA vs GG: OR=8.512, 95% CI=3.740-19.373, P=≤0.001; AA+AG vs GG: OR=1.869, 95% CI=1.161-3.008, P=0.010; and AA+AG vs GG: OR=4.773, 95% CI=3.181-7.162, P≤0.001). Subgroup analysis by ethnicity also revealed significant association in Caucasians. In addition, there was a significant association between TNF-α -308G>A polymorphism and celiac disease risk in Italy, Spain and PCR-FRLP group studies. CONCLUSION: Our meta-analysis suggests that the TNF-α -308G>A polymorphism plays an important role in celiac disease susceptibility. However, our results are still needed to strengthen by further studies in different ethnicities and larger sample sizes.

AbstractBackgroundBased on the current status of the COVID-19 global pandemic, there is an urgent need to systematically evaluate the effectiveness of wearing masks to protect public health from COVID-19 infection.MethodsWe conducted a systematic review and meta-analysis to evaluate the effectiveness of using face masks to prevent the spread of SARS-CoV-2. Relevant articles were retrieved from PubMed, Web of Science, ScienceDirect, Cochrane Library, and Chinese National Knowledge Infrastructure (CNKI), VIP (Chinese) database. There were no language restrictions. This study was registered with PROSPERO under the number CRD42020211862.ResultsA total of 6 case-control studies were included. In general, wearing a mask was associated with a significantly reduced risk of COVID-19 infection (OR = 0.38, 95% CI = 0.21-0.69, I2 = 54.1%). Heterogeneity modifiers were investigated by subgroup analysis. For healthcare workers group, masks were shown to have a reduce risk of infection by nearly 70%. Studies in China showed a higher protective effect than other countries. Adjusted estimates and subgroup analyses showed similar findings.ConclusionsThe results of this systematic review and meta-analysis support the conclusion that wearing a mask could reduce the risk of COVID-19 infection.

ABSTRACT Introduction: Many published studies have estimated the association of rs2435357 and rs1800858 polymorphisms in the proto-oncogene rearranged during transfection (RET) gene with Hirschsprung disease (HSCR) risk. However, the results remain inconsistent and controversial. Aim: To perform a meta-analysis get a more accurate estimation of the association of rs2435357 and rs1800858 polymorphisms in the RET proto-oncogene with HSCR risk. Methods: The eligible literatures were searched by PubMed, Google Scholar, EMBASE, and Chinese National Knowledge Infrastructure (CNKI) up to June 30, 2018. Summary odds ratios (ORs) and 95% confidence intervals (CIs) were used to evaluate the susceptibility to HSCR. Results: A total of 20 studies, including ten (1,136 cases 2,420 controls) for rs2435357 and ten (917 cases 1,159 controls) for rs1800858 were included. The overall results indicated that the rs2435357 (allele model: OR=0.230, 95% CI 0.178-0.298, p=0.001; homozygote model: OR=0.079, 95% CI 0.048-0.130, p=0.001; heterozygote model: OR=0.149, 95% CI 0.048-0.130, p=0.001; dominant model: OR=0.132, 95% CI 0.098-0.179, p=0.001; and recessive model: OR=0.239, 95% CI 0.161-0.353, p=0.001) and rs1800858 (allele model: OR=5.594, 95% CI 3.653-8.877, p=0.001; homozygote model: OR=8.453, 95% CI 3.783-18.890, p=0.001; dominant model: OR=3.469, 95% CI 1.881-6.396, p=0.001; and recessive model: OR=6.120, 95% CI 3.608-10.381, p=0.001) polymorphisms were associated with the increased risk of HSCR in overall. Conclusions: The results suggest that the rs2435357 and rs1800858 polymorphisms in the RET proto-oncogene might be associated with HSCR risk.

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.

Abstract Background Echinococcosis is a severe zoonotic disease that imposes a substantial burden on human life. Numerous studies on echinococcosis have involved a variety of risk factors, and it is difficult to evaluate the key risk factors. The objectives of this meta-analysis are to summarize available data on the prevalence of human echinococcosis and identify the key risk factors for echinococcosis. Methods Relevant studies were comprehensively searched in the PubMed, EMBASE, Web of Science, Cochrane, Chinese National Knowledge Infrastructure (CNKI), Chongqing VIP Information (VIP), Wanfang and SinoMed databases from database inception until August 22, 2020. A random-effects model was used to estimate the pooled odds ratio (OR) and 95% confidence interval (CI) by integrating the OR values of each risk factor. The I2 and Q statistics were calculated to evaluate the heterogeneity, and potential sources of heterogeneity were identified using sensitivity analysis and subgroup analysis. Publication bias was estimated by funnel plots and Egger’s test. Results A total of 1026 studies were identified through the database search, of which 26 were eligible for this meta-analysis. In total, 23 and 9 of the 26 studies were cystic echinococcosis (CE) and alveolar echinococcosis (AE) studies, respectively (6 papers included both AE and CE). The pooled prevalence of echinococcosis was 5.52% (95% CI: 5.47%-5.58%). Ethnicity (OR = 2.93, 95% CI: 1.81–4.75; I2 = 0), being a herder (OR = 2.66, 95%CI95% CI: 2.25–3.14; I2 = 8%), not washing hands before meals (OR = 2.40, 95% CI: 1.34–4.28; I2 = 82.8%) and being female (OR = 1.45, 95% CI: 1.26–1.66; I2 = 33.9%) were risk factors for AE. The top five risk factors for CE were ethnicity (OR = 3.18, 95% CI: 1.55–6.52; I2 = 79.2%), nomadism (OR = 2.71, 95% CI: 1.65–4.47; I2 = 55.8%), drinking nonboiled water (OR = 2.47, 95% CI: 1.36–4.47; I2 = 85.7), feeding viscera to dogs (OR = 2.35, 95% CI: 1.89–2.91; I2 = 21.5%), and being a herder (OR = 2.19, 95% CI: 1.67–2.86; I2 = 85.1%). The study design-specific subgroup analysis showed that the heterogeneity of CE risk factors decreased to varying degrees. Conclusions Specific characteristics (i.e., ethnicity and herder status) and behaviors (i.e., not washing hands before meals and feeding viscera to dogs ) are possible risk factors for echinococcosis. This study provided remarkable insight for future prevention and control of echinococcosis.

Object. The association of age at menopause with endometrial cancer remains controversial. Therefore, we quantitatively summarized the evidence from observational studies with a meta-analysis. Methods. We searched PubMed, Web of Science, Embase, Medline, Chinese National Knowledge Infrastructure (CNKI), and Wan Fang Med online up to March 2019, and all eligible case-control and cohort studies were included in the study. Pooled relative risks (RRs) with 95% confidence intervals (CIs) were calculated using the random-effects model. The dose-response relationship was assessed by restricted cubic spline model. The heterogeneity among studies was evaluated by I2. Metaregression was used to explore the potential sources of between-study heterogeneity. Egger’s test was used to estimate publication bias. Results. Eighteen articles including 957242 subjects with 4781 cases were included in the meta-analysis. The pooled RR (95%CI) of endometrial cancer for the highest versus the lowest age at menopause was 1.89 (95%CI: 1.58-2.26). For dose-response analysis, a nonlinear relationship was found between age at menopause and endometrial cancer, and the positive association became statistically significant when age at menopause was greater than 46.5 years old. Conclusions. This meta-analysis suggested that age at menopause was positively associated with endometrial cancer. For women whose menopausal age over 46.5 years old, the risk of endometrial cancer increased with the age at menopause.

Objectives. Electroacupuncture (EA), an extension of acupuncture, which is based on traditional acupuncture combined with modern electrotherapy, is commonly used for poststroke dysphagia (PSD) in clinical treatment and research. However, there is still a lack of sufficient evidence to recommend the routine use of EA for PSD. The aim of this study was to assess the efficacy and safety of EA in the treatment of PSD. Methods. Randomized controlled trials (RCTs) evaluating the effects of EA on PSD were identified through a comprehensive literature search of the PubMed, Embase, Cochrane Library, Web of Science, Chinese National Knowledge Infrastructure, Chinese Biomedical Database, and VIP databases from their inception to July 2020. The quality assessment of the included trials was performed based on the guidance of the Cochrane Reviewers’ Handbook, and meta-analysis (MA) was performed by using the RevMan 5.3 software. Results. Sixteen trials were identified, and these included 1,216 patients with PSD. The results demonstrated that EA in combination with swallowing rehabilitation training (SRT) was significantly superior to SRT alone with regard to effective rate (OR 5.40, 95% CI [3.78, 7.72], P < 0.00001 , water swallow test (WST) (MD −0.78, 95% CI [−1.07, −0.50], P < 0.00001 ), the video fluoroscopic swallowing study (VFSS) (MD 1.47, 95% CI [1.11, 1.84], P < 0.00001 ), the Ichiro Fujishima Rating Scale (IFRS) (MD 1.94, 95% CI [1.67, 2.22], P < 0.00001 ), and the incidence of aspiration pneumonia (IAP) (OR 0.20, 95% CI [0.06, 0.61], P = 0.005 ). Conclusions. The results showed that EA was better than the control treatment in terms of the effective rate, WST, VFSS, IFRS, and IAP of dysphagia after stroke. Strict evaluation standards and high-quality RCT designs are necessary for further exploration.

ObjectiveTo assess the comparative efficacy of traditional non-steroidal anti-inflammatory drugs (NSAIDs) and selective cyclo-oxygenase-2 inhibitors in patients with acute gout.DesignSystematic review and meta-analysis.Data sourcesMedline, Web of Science, China National Knowledge Infrastructure and Wanfang Data published as of 4 April 2020.MethodsWe performed meta-analysis of randomised controlled trials (RCTs) of traditional non-selective NSAIDs versus cyclo-oxygenase-2 inhibitors and RCTs of various cyclo-oxygenase-2 inhibitors in patients with acute gout. The main outcome measures were mean change in pain Visual Analogue Scale (VAS) score and 5-point Likert scale score on days 2–8.ResultsTwenty-four trials involving five drugs were evaluated. For pain Likert scale, etoricoxib was comparable to indomethacin (standardised mean difference (SMD): −0.09, 95% CI: −0.27 to 0.08) but better than diclofenac 50 mg three times a day (SMD: −0.53, 95% CI: −0.98 to 0.09). Regarding pain VAS score, etoricoxib was comparable to diclofenac 75 mg two times per day (SMD: −1.63, 95% CI: −4.60 to 1.34) and diclofenac 75 mg four times a day (SMD: −1.82, 95% CI: −5.18 to 1.53), while celecoxib was comparable to diclofenac 100 mg four times a day (SMD: −2.41, 95% CI: −5.91 to 1.09). Etoricoxib showed similar patients’ global assessment of response (SMD: −0.10, 95% CI: −0.27 to 0.07) and swollen joint count (SMD: −0.25, 95% CI: −0.74 to 0.24), but better investigator’s global assessment of response (SMD: −0.29, 95% CI: −0.46 to 0.11) compared with indomethacin. Etoricoxib showed more favourable pain VAS score than celecoxib (SMD: −2.36, 95% CI: −3.36 to 1.37), but was comparable to meloxicam (SMD: −4.02, 95% CI: −10.28 to 2.24). Etoricoxib showed more favourable pain Likert scale than meloxicam (SMD: −0.56, 95% CI: −1.10 to 0.02). Etoricoxib 120 mg four times a day was more likely to achieve clinical improvement than celecoxib 200 mg two times per day (OR: 4.84, 95% CI: 2.19 to 10.72).ConclusionAlthough cyclo-oxygenase-2 inhibitors and traditional non-selective NSAIDs may be equally beneficial in terms of pain relief, cyclo-oxygenase-2 inhibitors (especially etoricoxib) may confer a greater benefit.
