Migraine is a common and disabling neurological condition with a complex etiology. Recent advances in the understanding of the gut microbiome have shown the role of gut micro-organisms in disease outcomes for distant organs—including the brain. Interventions targeting the gut microbiome have been shown to be effective in multiple neurological diagnoses, but there is little research into the role of the microbiome in migraine. This systematic review seeks to assess the current research landscape of randomized placebo controlled trials utilizing probiotic interventions as migraine prophylaxis. Searches were conducted of scientific databases including PubMed, MEDLINE, and the Cochrane Library, following PRISMA guidelines. Of 68 screened studies, 2 were eligible for analysis. Due to methodological differences, meta-analysis was not possible. Qualitative comparison of the studies demonstrated a dichotomy of results—one trial reported no significant change in migraine frequency and intensity, while the second trial reported highly significant improvements. No clear ‘gold standard’ currently exists for microbiome research, let alone for migraine-related microbiome research. The heterogeneity of outcome measures used in the two trials included in this systematic review shows the need for a standardization of outcome measures, therefore a series of recommendations for future probiotic–migraine research are included.

AbstractA systematic review and random-effects model network meta-analysis was conducted to compare the efficacy, acceptability, tolerability, and safety of pharmacological interventions for adults with acute bipolar mania. We searched PubMed, the Cochrane Library, and Embase databases for eligible studies published before March 14, 2021. Randomized controlled trials (RCTs) of oral medication monotherapy lasting ≥10 days in adults with mania were included, and studies that allowed the use of antipsychotics as a rescue medication during a trial were excluded. The primary outcomes were response to treatment (efficacy) and all-cause discontinuation (acceptability). The secondary outcomes were the improvement of mania symptoms and discontinuation due to inefficacy. Of the 79 eligible RCTs, 72 double-blind RCTs of 23 drugs and a placebo were included in the meta-analysis (mean study duration = 3.96 ± 2.39 weeks, n = 16442, mean age = 39.55 years, with 50.93% males). Compared with the placebo, aripiprazole, asenapine, carbamazepine, cariprazine, haloperidol, lithium, olanzapine, paliperidone, quetiapine, risperidone, tamoxifen, valproate, and ziprasidone outperformed response to treatment (N = 56, n = 14503); aripiprazole, olanzapine, quetiapine, and risperidone had lower all-cause discontinuation; however, topiramate had higher all-cause discontinuation (N = 70, n = 16324). Compared with the placebo, aripiprazole, asenapine, carbamazepine, cariprazine, haloperidol, lithium, olanzapine, paliperidone, quetiapine, risperidone, tamoxifen, valproate, and ziprasidone outperformed the improvement of mania symptoms (N = 61, n = 15466), and aripiprazole, asenapine, carbamazepine, cariprazine, haloperidol, lithium, olanzapine, paliperidone, quetiapine, risperidone, valproate, and ziprasidone had lower discontinuation due to inefficacy (N = 50, n = 14284). In conclusions, these antipsychotics, carbamazepine, lithium, tamoxifen, and valproate were effective for acute mania. However, only aripiprazole, olanzapine, quetiapine, and risperidone had better acceptability than the placebo.

Recently, checkpoint inhibition of the PD-1/PD-L1 axis has been shown to be therapeutically relevant in urothelial carcinoma (UC). To evaluate the predictive and prognostic value of PD-L1 on response and survival in UC patients after cystectomy, chemotherapy, or anti-PD-1/PD-L1 therapy, a systematic review of PubMed, Embase, Web of Science, and the Cochrane Library was performed. A total of 2154 patients from 14 published studies were included. In all UC patients after cystectomy, tumour cell (TC) PD-L1 expression was not associated with the OS or PFS. For the subset of patients with organ-confined disease, TC PD-L1 expression significantly predicted OS after cystectomy (P=0.0004). There was no significant evidence of an association between TC PD-L1 status and ORR or OS for UC patients treated with platinum-based chemotherapy. For UC patients treated with anti-PD-1/PD-L1 therapy, TC PD-L1 expression≥5% could predict the response (P=0.005), but not for the 1% cut-off (P≥0.05). As for PD-L1 expression in tumour-inflating immune cells (TIICs), both subsets with IC2/3 vs. IC0/1 and IC1/2/3 vs. IC0 were associated with ORR to anti-PD-1/PD-L1 therapy. In the TIIC subset, IC2/3 vs. IC0/1 of PD-L1 was associated with higher CR (P=0.002), PR (P=0.04), and PD (P=0.007). Further, higher TIIC PD-L1 status benefited from longer PFS (P<0.001), but was not associated with OS in UC patients with anti-PD-1/PD-L1 therapy. Our study suggested that TIIC PD-L1 expression with 5% cut-off was valuable as a predictive and prognostic biomarker for ORR and PFS in UC patients with anti-PD-1/PD-L1 therapy.

Background.Increasing studies found that miR-126 expression may be associated with the prognosis of cancers. Here, we performed a meta-analysis to assess the prognostic role of miR-126 in different cancers.Methods.Eligible studies were identified by searching in PubMed, Embase, the Cochrane Library, CNKI, and Wan Fang databases up to March 2015. Pooled hazard ratios (HRs) and their corresponding 95% confidence intervals (CIs) were calculated to investigate the correlation between miR-126 and survival of cancers.Results.Thirty studies including a total of 4497 participants were enrolled in this meta-analysis. The pooled results showed that high level of miR-126 was a predictor for favorable survival of carcinomas, with pooled HR of 0.77 (95% CI 0.64–0.93) for OS, 0.64 (95%CI 0.48–0.85) for DFS, and 0.70 (95% CI 0.50–0.98) for PFS/RFS/DSS. However, high level of circulating miR-126 predicted a significantly worse OS in patients with cancer (HR = 1.65, 95% CI 1.09–2.51).Conclusions.Our results indicated that miR-126 could act as a significant biomarker in the prognosis of various cancers.

Background: Femoroacetabular impingement is a common and debilitating source of hip pain in young adults. Although physiotherapy is used as a mainstay of nonoperative care for femoroacetabular impingement, the evidence regarding different physiotherapy practices is poorly understood. Purpose: To collect and synthesize the best available evidence and arrive at a summary estimate of treatment effect for the utility of physiotherapy in the management of femoroacetabular impingement. Study Design: Meta-analysis. Methods: A systematic review was performed on February 2, 2019, of PubMed, EMBASE, and Cochrane Library databases using “femoroacetabular impingement OR hip pain” and “physiotherapy OR nonoperative management” and their synonyms as search terms. Central treatment themes were identified across protocols, and pooled analyses were conducted to assess for differences in patient-reported outcome measures across these themes. Results: A total of 5 randomized controlled trials met our inclusion criteria. The studies included 124 patients with a mean age of 35 years, of whom 24% were male. The average follow-up was 9.4 weeks (range, 6-12 weeks), and the follow-up rate across all participants was 86%. Among these 5 studies, 4 studies used a physiotherapy protocol that focused on core strengthening versus no core strengthening, 4 studies compared active strengthening versus passive modalities, and 3 studies compared supervised versus unsupervised physiotherapy. Pooled analysis across all studies demonstrated improved outcomes in the treatment groups compared with the controls (standardized mean difference [SMD], 0.76; 95% CI, 0.38-1.13; P < .0001). Core strengthening (SMD, 0.82; 95% CI, 0.39-1.26; P = .0002), active physiotherapy (SMD, 0.70; 95% CI, 0.29-1.10; P = .0008), and supervised physiotherapy (SMD, 0.58; 95% CI, 0.14-1.03; P = .01) were found to result in statistically significant improvements in functional outcomes compared with no core strengthening, passive modalities, and unsupervised care, respectively. Conclusion: Supervised physiotherapy programs focusing on active strengthening and core strengthening are more effective than unsupervised, passive, and non–core focused programs. Future studies with longer term follow-up and validated femoroacetabular impingement specific outcome measures are required to determine prognostic factors for success with nonoperative care as well as to determine the ideal patient profile and structured rehabilitation protocol.

<b><i>Introduction:</i></b> Ischaemia-modified albumin (IMA) is a new, sensitive marker of ischaemic diseases that has been approved for diagnosing myocardial ischaemia. However, the accuracy of IMA in the diagnosis of stroke remains to be clarified. The study’s purpose is to assess the potential role of IMA as a diagnostic indicator in stroke. <b><i>Methods:</i></b> We carried out a systematic search in Medline, the Cochrane Library, Embase, Scopus, Science Direct, ISI Web of Knowledge, and the reference lists of relevant articles from the databases’ inception to September 1, 2019. Studies that appraised the diagnostic accuracy of IMA for acute stroke patients were included in our study. Two reviewers extracted data independently and assessed the quality of the retrieved studies, and disagreements were resolved through discussions with a third reviewer. Sensitivities and specificities were pooled by using bivariate diagnostic meta-analysis. We calculated <i>I</i><sup>2</sup> to test the heterogeneity and used meta-regression to identify potential sources of heterogeneity. This systematic review and meta-analysis is registered in international prospective register of systematic reviews (number CRD42020149174). <b><i>Results:</i></b> Six studies with 605 patients were eligible for inclusion. Our meta-analysis produced the following outcomes: the mean sensitivity of IMA in diagnosing acute stroke was 0.80 (95% confidence interval [CI], 0.69–0.88) and the specificity was 0.80 (95% CI, 0.71–0.87). The area under the receiver operating characteristic curve was 0.86 (95% CI, 0.83–0.89), and the pooled diagnostic odds ratio was 16 (95% CI, 8–33). There was obvious heterogeneity between studies (<i>I</i><sup>2</sup> = 78%, 95% CI, 53–100). Sensitivity analysis and meta-regression could account for the heterogeneity. <b><i>Conclusion:</i></b> IMA is a helpful marker for consideration in the early diagnosis of stroke.

The aim of this systematic review was to determine how effective acupuncture or electroacupuncture (acupuncture with electrical stimulation) is in treating poststroke patients with spasticity. We searched publications in Medline, EMBASE, and the Cochrane Library in English, 19 accredited journals in Korean, and the China Integrated Knowledge Resources Database in Chinese through to July 30, 2013. We included randomized controlled trials (RCTs) with no language restrictions that compared the effects of acupuncture or electroacupuncture with usual care or placebo acupuncture. The two investigators assessed the risk of bias and statistical analyses were performed. Three RCTs in English, 1 in Korean, and 1 in Chinese were included. Assessments were performed primarily with the Modified Ashworth Scale (MAS). Meta-analysis showed that acupuncture or electroacupuncture significantly decreased spasticity after stroke. A subgroup analysis showed that acupuncture significantly decreased wrist, knee, and elbow spasticity in poststroke patients. Heterogeneity could be explained by the differences in control, acupoints, and the duration after stroke occurrence. In conclusion, acupuncture could be effective in decreasing spasticity after stroke, but long-term studies are needed to determine the longevity of treatment effects.

Purpose. This study aimed to evaluate the therapeutic value of adalimumab (ADA) for fistula in Crohn’s disease (CD). Methods. A computerized search of electronic databases, including PubMed, Web of Science, Embase, Google scholar, and the Cochrane Library from 2000 to October 2016, was performed. Randomized controlled trials (rcts) or nonrandomized controlled trials (n-rcts) were included in this article to evaluate the role of ADA in the management of fistula in CD. The methodological index for nonrandomized studies (MINORS evaluation tools) was used to assess the quality of every study. Result. Overall, seven studies and 379 patients comforted to the inclusion criteria of this meta-analysis. The result showed that 36% (95% CI: 0.31–0.41) of patients with complete fistula closure and 31% (95% CI: 0.031–0.61) of patients with partial response were received in CD with ADA treatment. Conclusion. We concluded that ADA is effective and safe for the treatment of fistula in CD according to current evidence.

Aims To investigate the association between TBI and stroke risk. Summary of review We undertook a systematic review of MEDLINE, EMBASE, CINAHL, and The Cochrane Library from inception to 4th December 2020. We used random-effects meta-analysis to pool hazard ratios (HR) for studies which reported stroke risk post-TBI compared to controls. Searches identified 10,501 records; 58 full texts were assessed for eligibility and 18 met the inclusion criteria. The review included a large sample size of 2,606,379 participants from four countries. Six studies included a non-TBI control group, all found TBI patients had significantly increased risk of stroke compared to controls (pooled HR 1.86; 95% CI 1.46-2.37). Findings suggest stroke risk may be highest in the first four months post-TBI, but remains significant up to five years post-TBI. TBI appears to be associated with increased stroke risk regardless of severity or subtype of TBI. There was some evidence to suggest an association between reduced stroke risk post-TBI and Vitamin K antagonists and statins, but increased stroke risk with certain classes of antidepressants. Conclusion TBI is an independent risk factor for stroke, regardless of TBI severity or type. Post-TBI review and management of risk factors for stroke may be warranted.

The role of adjuvant transarterial chemoembolization (TACE) for patients with resectable hepatocellular carcinoma (HCC) undergoing hepatectomy is currently unclear. We performed a systematic review of the literature using the MEDLINE, Embase, and Cochrane Library databases. Random-effects meta-analysis was carried out to compare the overall survival (OS) and recurrence-free survival (RFS) of patients with resectable HCC undergoing hepatectomy followed by adjuvant TACE vs. hepatectomy alone in randomized controlled trials (RCTs). The risk of bias was assessed using the Risk of Bias 2.0 tool. Meta-regression analyses were performed to explore the effect of hepatitis B viral status, microvascular invasion, type of resection (anatomic vs. parenchymal-sparing), and tumor size on the outcomes. Ten eligible RCTs, reporting on 1216 patients in total, were identified. The combination of hepatectomy and adjuvant TACE was associated with superior OS (hazard ratio (HR): 0.66, 95% confidence interval (CI): 0.52 to 0.85; p < 0.001) and RFS (HR: 0.70, 95% CI: 0.56 to 0.88; p < 0.001) compared to hepatectomy alone. There were significant concerns regarding the risk of bias in most of the included studies. Overall, adjuvant TACE may be associated with an oncologic benefit in select HCC patients. However, the applicability of these findings may be limited to Eastern Asian populations, due to the geographically restricted sample. High-quality multinational RCTs, as well as predictive tools to optimize patient selection, are necessary before adjuvant TACE can be routinely implemented into standard practice.
