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.

Purpose: To systematically evaluate the effects of mind-body exercises (Tai Chi, Yoga, and Health Qigong) on motor function (UPDRS, Timed-Up-and-Go, Balance), depressive symptoms, and quality of life (QoL) of Parkinson’s patients (PD). Methods: Through computer system search and manual retrieval, PubMed, Web of Science, The Cochrane Library, CNKI, Wanfang Database, and CQVIP were used. Articles were retrieved up to the published date of June 30, 2019. Following the Cochrane Collaboration System Evaluation Manual (version 5.1.0), two researchers independently evaluated the quality and bias risk of each article, including 22 evaluated articles. The Pedro quality score of 6 points or more was found for 86% (19/22) of these studies, of which 21 were randomized controlled trials with a total of 1199 subjects; and the trial intervention time ranged from 4 to 24 weeks. Interventions in the control group included no-intervention controls, placebo, waiting-lists, routine care, and non-sports controls. Meta-analysis was performed on the literature using RevMan 5.3 statistical software, and heterogeneity analysis was performed using Stata 14.0 software. Results: (1) Mind-body exercises significantly improved motor function in PD patients, including UPDRS (SMD = −0.61, p < 0.001), TUG (SMD = −1.47, p < 0.001) and balance function (SMD = 0.79, p < 0.001). (2) Mind-body exercises also had significant effects on depression (SMD = −1.61, p = 0.002) and QoL (SMD = 0.66, p < 0.001). (3) Among the indicators, UPDRS (I2 = 81%) and depression (I2 = 91%) had higher heterogeneity; according to the results of the separate combined effect sizes of TUG (I2 = 29%), Balance (I2 = 16%) and QoL (I2 = 35%), it shows that the heterogeneity is small; (4) After meta-regression analysis of the age limit and other possible confounding factors, further subgroup analysis showed that the reason for the heterogeneity of UPDRS motor function may be related to the sex of PD patients and severity of the disease; the outcome of depression was heterogeneous. The reason for this may be the use of specific drugs in the experiment and the duration of intervention in the trial. Conclusion: (1) Mind-body exercises were found to have significant improvements in motor function, depressive symptoms, and quality of life in patients with Parkinson’s disease, and can be used as an effective method for clinical exercise intervention in PD patients. (2) Future clinical intervention programs for PD patients need to fully consider specific factors such as gender, severity of disease, specific drug use, and intervention cycle to effectively control heterogeneity factors, so that the clinical exercise intervention program for PD patients is objective, scientific, and effective.

Purpose. To clarify the relationship between certain genotypes or alleles of the APOE gene and the onset risk of Parkinson’s disease dementia (PDD). Methods. The PubMed, Cochrane, Embase, CBM, CNKI, and Wanfang databases were searched to identify all case-control studies and cohort studies published before October 30, 2017, that investigated the association between the APOE gene and the onset of PDD. Manual information retrieval was also performed. All studies that met the quality requirements were included in a meta-analysis performed using RevMan 5.3 software. Results. The meta-analysis included 17 studies, with a total of 820 patients in the PDD group and 1,922 in the non-PDD group. The influence of the APOE gene on PDD onset was analyzed from three aspects: five genotypes vs. ε3/3, ε2+/ε4+ vs. ε3/3, and ε4+ vs. ε4−. The risk factors for PDD may include the genotypes ε3/4 (OR 1.47, 95% CI 1.14–1.89) and ε4/4 (OR 2.93, 95% CI 1.20–7.14). In patients with PDD, there was no significant difference in the distribution of ε2+ vs. ε3/3 (OR 1.35, 95% CI 0.97–1.87, P=0.07). The risk of PDD was 1.61 times greater in ε4+ compared with ε3/3 (OR 1.61, 95% CI 1.24–2.08, P=0.0003). As the results indicated that ε2+ did not play a role as a risk factor or a protective factor, we divided the population into ε4+ and ε4− for the meta-analysis and found that, among patients with Parkinson’s disease, the dementia risk of those with ε4+ was 1.72 times greater than that of those with ε4− (OR 1.72, 95% CI 1.41–2.10, P<0.00001). Subgroup analysis in accordance with different geographical regions revealed that ε4+ was a risk factor for PDD in people from all regions. Conclusions. Among the APOE genotypes, ε2+ is neither a risk factor nor a protective factor for PDD, while ε4+ is a risk factor for PDD. The present results are applicable to Asian, European, and American patients with Parkinson’s disease. Regarding the single APOE genotypes, ε3/4 and ε4/4 may be risk factors for PDD; however, further studies with large sample sizes are needed to verify this.

Abstract Background: Hepatocellular carcinoma (HCC) and cholangiocarcinoma are the most common liver malignant tumors worldwide. Investigating the molecular basis of these malignancies is vital to the development of new treatments. Recent studies have found that mutation and abnormal expression of ARID1A, are frequently shown in HCC and cholangiocarcinoma. Herein, we aimed to estimate the effects of ARID1A mutation and expression on prognosis of HCC and cholangiocarcinoma.Methods: We searched PubMed, EMBASE, Web of Science, the Cochrane Library for studies evaluating the relationship between ARID1A mutations or expression and the survival of HCC or cholangiocarcinoma patients. Meta-analysis was performed to generate a combined HR with a 95% confidence interval (CI) for overall survival (OS).Results: We identified 12 articles that evaluated the impact of ARID1A mutation or expression on the prognosis of patients with HCC or cholangiocarcinoma. Six studies provided data on HCC survival and 6 studies examined cholangiocarcinoma survival. For HCC, ARID1A mutation carriers or patients with low ARID1A expression had worse OS (HR = 1.75; 95% CI = 1.22–2.51) than non-carriers or patients with high ARID1A expression. For cholangiocarcinoma, ARID1A mutation carriers or patients with low ARID1A expression also had significantly shorter OS (HR = 3.70, 95% CI = 2.88–4.76).Conclusions: Our study suggests that ARIDIA mutation or low expression is strongly associated with poor prognosis of patients with HCC or cholangiocarcinoma, and may be considered as a potential prognostic biomarker for these patients.

As a popular method, virtual reality (VR) is still controversial in its effect on the balance function of patients with Parkinson’s disease. This systematic review aims to discuss such effects of VR and to compare it with that resulting from traditional therapies. A comprehensive search was conducted for randomized controlled trials published from 2000 to 2020 through the following databases: PubMed, Web of Science, CINAHL, Embase, Cochrane Library. Fifteen articles were included for the systematic review. An evaluation on their methodological qualities was performed using the PEDro scale, followed by an assessment of their risk of biases in accordance with the Cochrane Handbook for Systematic Reviews of Interventions for quality assessment. In terms of dynamic balance, the BBS score of the VR group was significantly improved when compared with the control group (SMD = 0.52, 95% CI = 0.31–0.73). However, no significant difference was observed between the two groups on TUG (SMD = −0.26; 95% CI = −0.62–0.1; p = 0.16). Besides, the VR group also showed better results in improving patients’ static balance, balance confidence, and quality of life. A funnel plot was created to investigate the effects of each study included in the meta-analysis in order to identify any existing publication bias. This systematic review shows that the application of VR leads to more significant improvement in the balance of patients with Parkinson’s disease than having them perform traditional exercises. It can be used as an auxiliary method of rehabilitation.

Purpose: The purpose of this study was to determine the relationship between Kinesin like protein 6 (KIF6) gene Trp719Arg and major cardiovascular events (MACEs) risk in subjects who received statin therapy. Methods: PubMed, EmBase, and the Cochrane Library were searched from inception through September 2017. The selected studies evaluated the association of Trp719Arg with MACEs in individuals who received statins. Relative risk (RR) and 95% confidence interval (CI) were used to evaluate the effect of statin therapy on MACEs in subjects carrying polymorphisms, and the odds ratio (OR) and 95% CI were used to evaluate the relationship between Trp719Arg and MACE risk in individuals who received statins, using the random-effects model. Results: Seven studies were included (N=48,885). Overall, we found that statin therapy significantly reduced the risk for MACEs in subjects carrying ArgArg (RR: 0.79; 95% CI: 0.69-0.90; P=0.001), ArgTrp (RR: 0.71; 95% CI: 0.60 -0.83; P<0.001), ArgArg+ArgTrp (RR: 0.71; 95% CI: 0.63 -0.81; P<0.001), and TrpTrp (RR: 0.79; 95% CI: 0.73-0.85; P<0.001). Furthermore, there was no significant difference between subjects carrying ArgArg and those carrying TrpTrp (OR: 1.11; 95% CI: 0.92-1.34; P=0.265). However, ArgTrp (OR: 1.29; 95% CI: 1.07-1.55; P=0.007) and ArgArg+ArgTrp (OR: 1.26; 95% CI: 1.05-1.51; P=0.012) were associated with an increased risk for MACEs when compared with TrpTrp. Conclusions: Statin therapy significantly reduced the risk for MACEs in subjects carrier specific KIF6 gene Trp719Arg polymorphisms. Further, subjects carrying ArgTrp or ArgArg+ArgTrp had a greater incidence of MACEs as compared with TrpTrp when they received statins.

We aimed to comprehensively analyse the safety and efficiency of rotigotine for treating Parkinson’s disease (PD). We conducted systematic literature searches of Cochrane library, PubMed and Embase databases up to April 2016, with ‘Rotigotine’, ‘Parkinson Disease ’ and ‘Parkinson’s disease’ as key searching terms. Outcomes, including Unified Parkinson’s Disease Rating Scale (UPDRS) Part III and Part II scores, ‘off’ time, adverse events (AEs), serious AEs and discontinuation because of AEs, were compared between rotigotine and placebo groups under a fixed or random effect model. For dichotomous and continuous data, risk ratio (RR) and weighted mean difference with their corresponding 95% confidence intervals (95% CIs) were taken as the effect sizes to calculate merged results. Twelve eligible studies were included. For patients with early or advanced PD, rotigotine could significantly improve UPDRS Part III and Part II scores (p < 0.001) and it had significantly higher incidence of AEs than the placebo (p < 0.001). Regarding discontinuation because of AEs, rotigotine showed a significant advantage over placebo in patients with early PD, whereas the overall result demonstrated no statistically significant difference between the groups. Rotigotine can improve daily living and motor ability of patients with PD, although it has higher incidence of AEs. Rotigotine might be more appropriate for patients with advanced PD than for those with early PD. This article is open to POST-PUBLICATION REVIEW.

Background. Hyposmia is one of the most common and best-characterized conditions that is also one of the first nonmotor features of Parkinson’s disease (PD). The association of hyposmia with PD is widely accepted; however the likelihood of developing PD is unclear. Our meta-analysis aimed to investigate the risk of PD in individuals with hyposmia.Methods. Prospective studies on humans published before December4th, 2018, were searched for in PubMed, Embase, Web of Science, and Cochrane Library databases. Two independent reviewers screened studies for inclusion and extracted data. We assessed the quality of studies using the Newcastle–Ottawa Scale and pooled data for analysis using random-effects models.Results. Of the 1774 studies retrieved, seven met the inclusion criteria for this review. A total of 3272 hyposmia and 176 PD events were reported over follow-up periods ranging from 3 to 17 years. Hyposmia was associated with a 3.84-fold risk of developing PD (pooled relative risk: 3.84, 95% CI 2.12−6.95). Subgroup analyses identified few differences between different hyposmia assessment methodologies and follow-up periods.Conclusions. Our findings suggest that deficiencies in olfaction are associated with an increased risk of developing PD. Future studies are needed to investigate whether hyposmia is a promising and feasible biomarker for the early diagnosis of PD.

Background/Aims: A network meta-analysis is used to compare the efficacy of ropinirole, rasagiline, rotigotine, entacapone, apomorphine, pramipexole, sumanirole, bromocriptine, piribedil and levodopa, with placebo as a control, for non-motor symptoms in Parkinson’s disease (PD). Methods: PubMed, Embase and the Cochrane Library were searched from their establishment dates up to January 2017 for randomized controlled trials (RCTs) investigating the efficacy of the above ten drugs on the non-motor symptoms of PD. A network meta-analysis combined the evidence from direct comparisons and indirect comparisons and evaluated the pooled weighted mean difference (WMD) values and surfaces under the cumulative ranking curves (SUCRA). The network meta-analysis included 21 RCTs. Results: The analysis results indicated that, using the United Parkinson’s Disease Rating Scale (UPDRS) III, the efficacies of placebo, ropinirole, rasagiline, rotigotine, entacapone, pramipexole, sumanirole and levodopa in treating PD were lower than that of apomorphine (WMD = -10.90, 95% CI = -16.12∼-5.48; WMD = -11.85, 95% CI = -17.31∼-6.16; WMD = -11.15, 95% CI = -16.64∼-5.04; WMD = -11.70, 95% CI = -16.98∼-5.60; WMD = -11.04, 95% CI = -16.97∼-5.34; WMD = -13.27, 95% CI = -19.22∼-7.40; WMD = -10.25, 95% CI = -15.66∼-4.32; and WMD = -11.60, 95% CI = -17.89∼-5.57, respectively). Treatment with ropinirole, rasagiline, rotigotine, entacapone, pramipexole, sumanirole, bromocriptine, piribedil or levodopa, with placebo as a control, on PD exhibited no significant differences on PD symptoms when the UPDRS II was used for evaluation. Moreover, using the UPDRS III, the SUCRA values indicated that a pomorphine had the best efficacy on the non-motor symptoms of PD (99.0%). Using the UPDRS II, the SUCRA values for ropinirole, rasagiline, rotigotine, entacapone, pramipexole, sumanirole, bromocriptine, piribedil and levodopa treatments, with placebo as a control, indicated that bromocriptine showed the best efficacy on the non-motor symptoms of PD (75.6%). Conclusion: Among ropinirole, rasagiline, rotigotine, entacapone, apomorphine, pramipexole, sumanirole, bromocriptine, piribedil and levodopa, with placebo as a control, apomorphine may be the most efficacious drug for therapy in treating the non-motor symptoms of PD.

Abstract Background Transanal total mesorectal excision (TaTME) appears to have favorable surgical and pathological outcomes. However, the evidence on survival outcomes remains unclear. We performed a meta-analysis to compare long-term oncologic outcomes of TaTME with transabdominal TME for rectal cancer. Methods PubMed, EMBASE, and the Cochrane Library were searched. Data were pooled, and overall effect size was calculated using random-effects models. Outcome measures were overall survival (OS), disease-free survival (DFS), and local and distant recurrence. Results We included 11 nonrandomized studies that examined 2,143 patients for the meta-analysis. There were no significant differences between the two groups in OS, DFS, and local and distant recurrence with a RR of 0.65 (95% CI 0.39–1.09, I2 = 0%), 0.79 (95% CI 0.57–1.10, I2 = 0%), 1.14 (95% CI 0.44–2.91, I2 = 66%), and 0.75 (95% CI 0.40–1.41, I2 = 0%), respectively. Conclusion In terms of long-term oncologic outcomes, TaTME may be an alternative to transabdominal TME in patients with rectal cancer. Well-designed randomized trials are warranted to further verify these results.

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.
