Background and Objective: Myasthenia gravis (MG) is an autoimmune neuromuscular disease. Nearly 10–30% of patients with MG are refractory to conventional therapy. Rituximab (RTX), a monoclonal antibody targeting CD20, is increasingly used in autoimmune disorders. We performed a systematic review and meta-analysis to evaluate the effectiveness and safety of RTX for refractory MG.Methods: Studies published between January 1, 2000 and January 17, 2021 were searched in PubMed, EMBASE, Cochrane Library, and ClincalTrails.gov. Primary outcomes included proportion of patients achieving minimal manifestation status (MMS) or better and quantitative MG (QMG) score change from baseline. Secondary outcomes were glucocorticoids (GC) doses change from baseline and proportion of patients discontinuing oral immunosuppressants.Results: A total of 24 studies involving 417 patients were included in the meta-analysis. An overall 64% (95% confidence interval, 49–77%) of patients achieved MMS or better. The estimated reduction of QMG score was 1.55 (95% confidence interval, 0.88–2.22). The mean reduction of GC doses was 1.46 (95% confidence interval, 1.10–1.82). The proportion of patients discontinuing oral immunosuppressants was 81% (95% confidence interval, 66–93%). Subgroup analyses showed that the proportion of patients achieving MMS or better and discontinuing oral immunosuppressants was higher in MuSK-MG group than those in AChR-MG group. Improvement was more pronounced in patients with mild to moderate MG compared to those with severe MG. Moreover, the efficacy appeared to be independent of the dose of RTX. 19.6% of patients experienced adverse events, most of which were mild to moderate. Only one patient developed progressive multifocal leukoencephalopathy.Conclusions: RTX can alleviate the symptom of weakness, decrease QMG score and reduce the doses of steroids and non-steroid immunosuppressive agents in refractory MG. It is well-tolerated with few severe adverse events. Randomized controlled trials are urgently needed to study the efficacy of RTX in treating refractory MG and to identify the characteristics of patients who might respond well to RTX.

Professionals use foam rollers to improve range of motion (ROM). Recently, a vibrating foam roller (VFR) that combines the vibration function with a foam roller (FR) has been used. The purpose of this systematic review and meta-analysis was to determine the effects of a VFR on the improvement of ROM in healthy individuals. A systematic literature search was carried out in five international databases: PubMed, Embase, PEDro, Cochrane Library, and Google Scholar. Eight clinical studies, composed of six randomized controlled trials and two randomized crossover trials that involved 230 healthy participants were selected for analysis. Methodological quality was identified using the PEDro scale. The mean scores, 4.75±0.71, of the eight included studies, were classified as fair. The results demonstrated that the VFR achieved better gains than the FR in improving ROM (standardized mean difference [SMD], 0.53; 95% confidence intervals [CIs], 0.29–0.77; I2=55%). The VFR was more effective in improving the ROM than the FR in the hip and knee joints (hip: SMD, 0.56; 95% CI, 0.28–0.85; I2=0%; knee: SMD, 0.86; 95% CI, 0.42–1.30; I2=79%). The VFR may be an additional option to improve the ROM in healthy adults and athletes.

Introduction: Approximately 10–20% of patients WITH myasthenia gravis (MG) are refractory to conventional immunotherapies. The purpose of this study was to conduct a systematic review and meta-analysis to explore the optimal therapies for refractory MG.Method: Correlative studies were performed through a search in PubMed, Cochrane Library, and Embase databases. The primary outcome was defined by changes in the quantitative myasthenia gravis score (QMG). Secondary outcomes were defined by the Myasthenia Gravis Activities of Daily Living Scale (MG-ADL), Myasthenia Gravis Foundation of America (MGFA) post intervention status, adverse events, and disease exacerbation after treatment.Result: A total of 16 studies were included with 403 patients with refractory MG on therapies with rituximab, eculizumab, tacrolimus, and cladribine. Therapeutic efficacy of rituximab and eculizumab was identified with an estimated reduction in QMG score (4.158 vs. 6.928) and MG-ADL (4.400 vs. 4.344), respectively. No significant changes were revealed in efficacy or exacerbation density between the two independent therapeutic cohorts. The estimated adverse event density of eculizumab was more significant than that in the rituximab group (1.195 vs. 0.134 per patient-year), while the estimated serious event density was similar.Conclusion: The efficacy and safety of rituximab and eculizumab have been approved in patients with refractory MG. Rituximab had a superior safety profile than eculizumab with a lower incidence of adverse events.Systematic Review Registration:https://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42021236818, identifier CRD42021236818.

Abstract Rituximab-cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) given every 21 days is considered the treatment of choice for most patients with aggressive lymphoma. Despite improved survival with the addition of rituximab to chemotherapy, the event- free rates and survival rates of patients with aggressive lymphoma are unsatisfactory. Decreasing the interval from 3 weeks of treatment (CHOP-21) to 2 weeks (CHOP-14) may improve outcome of patients with aggressive lymphoma, though its toxicity might be higher. A number of randomized controlled trials (RCT) examined the efficacy of CHOP-like (with or without rituximab) given every 14 days (CHOP-14) compared to standard CHOP-like given every 21 days (CHOP-21) for patients with aggressive lymphoma. Results of these trials were conflicting. In order to evaluate the effect of CHOP-14 on overall survival (OS), disease control and toxicity of patients with aggressive lymphoma we performed a systematic review and meta-analysis of RCTs. Methods We included RCTs that compared CHOP-14 or CHOP-like-14 to the same regimen given every 21 days for patients with aggressive lymphoma. Rituximab could be given in addition to chemotherapy in both groups. In June 2013 we searched The Cochrane Library, MEDLINE, LILACS, conference proceedings, and databases of ongoing trials. Authors were contacted for complementary data. The primary outcome was OS. Relative risk (RR) for dichotomous data and hazard ratio (HR) for time to event data were estimated and pooled. We used fixed effect model to pool data. Results We identified 7 trials, conducted between the years 1999 and 2008 and that randomized 4073 adult patients. In 3 trials rituximab was added to the CHOP-like regimen. The median age ranged from 50 years to 70 years. In 6 trials growth factors support was added to all patients allocated to CHOP-14, and at the discretion of the treating physician to those allocated to CHOP-21. Five trials were judged to be at low risk for selection bias (allocation concealment and sequence generation). Three trials were judged to be at low risk of attrition bias (incomplete outcome data). Risk of bias of these domains was unclear for the other trials. Rate of exclusion after randomization ranged from 0 (in 3 trials) to 18%, median 8.8%. All trials (3749 patients) were included in analysis of OS. In one trial (Pfreundschuh NHL-B1 2004) relevant outcomes were reported only of the cohort of patients treated with CHOP, and not for those treated with CHOEP. CHOP-like-14 improved OS of patients with aggressive lymphoma compared to the same regimen given every 21 days: HR of death 0.83, 95% confidence interval (CI) 0.73-0.93, I2 of heterogeneity 32%. No such benefit was shown in the analysis of the 3 trials that included patients who received rituximab in combination the chemotherapy HR 0.93 95% CI 0.78-1.10. No statistically significant difference in PFS (HR 1.00 95% CI 0.85-1.17) and complete response rate (HR 1.03 95% CI 0.98-1.07) was shown. Likewise, treatment related mortality, grade 3-4 infection, febrile neutropenia, and discontinuation rate did not differ between the groups. Conclusions CHOP-like regimen was shown to improve OS when given every 14 days instead of 21 days. However, with the addition of rituximab no such benefit was shown. R-CHOP-21 remains the standard of care for patient with aggressive B-cell lymphoma. CHOP-14 can be considered as in case rituximab is omitted. CI = confidence interval; IV = inverse of variance; SE = standard error; Zhang 2009 reported survival as 2 separate cohorts (patients with GCB and non-GCB lymphoma) as represented in the figure. Disclosures: No relevant conflicts of interest to declare.

Patients who undergo abdominal surgery under general anesthesia develop hypothermia in 80–90% of the cases within an hour after induction of anesthesia. Side effects include shivering, bleeding, and infection at the surgical site. However, the surgical team applies forced air warming to prevent peri-operative hypothermia, but these methods are insufficient. This study aimed to confirm the optimal application method of forced air warming (FAW) intervention for the prevention of peri-operative hypothermia during abdominal surgery. A systematic review and meta-analysis were conducted to provide a synthesized and critical appraisal of the studies included. We used PubMed, EMBASE, CINAHL, and Cochrane Library CENTRAL to systematically search for randomized controlled trials published through March 2020. Twelve studies were systematically reviewed for FAW intervention. FAW intervention effectively prevented peri-operative hypothermia among patients undergoing both open abdominal and laparoscopic surgery. Statistically significant effect size could not be confirmed in cases of only pre- or peri-operative application. The upper body was the primary application area, rather than the lower or full body. These findings could contribute detailed standards and criteria that can be effectively applied in the clinical field performing abdominal surgery.

Several retrospectivee described the association of interstitial lung disease (ILD) and ANCA-associated vasculitis (AAV). However, the relationship between the ILD and mortality in AAV patients have not been established so far. This study aims to estimate the relevance of AAV-associated-ILD (AAV-ILD) and mortality risk by conducting a systematic review and meta-analysis.A comprehensive systematic review was conducted in accordance with the guidelines of PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses). PubMed, Embase.com and the Cochrane Library (Wiley) were searched for original observational studies. Summary estimates were derived with a random-effects model and reported as risk ratio (RR), tested for publication bias and heterogeneity. Ten retrospective cohort studies were included, comprising 526 AAV-ILD patients enrolled from 1974 to 2018. Meta-analysis yielded a pooled RR of 2.90 (95% confidence interval 1.77–4.74) for death among those with AAV-ILD compared to control group. UIP pattern was associated with an even poorer prognosis in comparison to non-UIP pattern (RR 4.36, 95% confidence interval 1.14–16.78). Sensitivity analysis suggested that the meta-RR result was not skewed by a single dominant study. ILD might be associated with a higher mortality risk in AAV patients.

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.

ABSTRACTPurposeof Review: To investigate the efficacy and safety of CVT-301 for motor fluctuation in Parkinson’s disease (PD).Recent Findings:This study demonstrated that the CVT-301 group had a higher proportion of patients achieving an ON state than the placebo group (OR=2.68; 95% CI: 1.86-3.86; p<0.00001). Moreover, CVT-301 had also shown to improve motor function by UPDRS-III score (SMD=3.83; 95% CI: 2.44-5.23; p<0.00001) and promote an overall improvement of PD by PGIC self-rating (OR=2.95; 95% CI: 1.78-4.9; p<0.00001). The most common adverse events encountered were respiratory symptoms (OR=12.18; 95% CI: 5.01-29.62; p<0.00001) and nausea (OR=3.95; 95% CI: 1.01-15.41; p=0.05).Summary:CVT-301 had the potential to be an alternative or even a preferred treatment for motor fluctuation in PD patients.

Background: Nervous and muscular adverse events (NMAEs) have garnered considerable attention after the vaccination against coronavirus disease (COVID-19). However, the incidences of NMAEs remain unclear. We aimed to calculate the pooled event rate of NMAEs after COVID-19 vaccination. Methods: A systematic review and meta-analysis of clinical trials on the incidences of NMAEs after COVID-19 vaccination was conducted. The PubMed, Medline, Embase, Cochrane Library, and Chinese National Knowledge Infrastructure databases were searched from inception to 2 June 2021. Two independent reviewers selected the study and extracted the data. Categorical variables were analyzed using Pearson’s chi-square test. The pooled odds ratio (OR) with the corresponding 95% confidence intervals (CIs) were estimated and generated with random or fixed effects models. The protocol of the present study was registered on PROSPERO (CRD42021240450). Results: In 15 phase 1/2 trials, NMAEs occurred in 29.2% vs. 21.6% (p < 0.001) vaccinated participants and controls. Headache and myalgia accounted for 98.2% and 97.7%, and their incidences were 16.4% vs. 13.9% (OR = 1.97, 95% CI = 1.28–3.06, p = 0.002) and 16.0% vs. 7.9% (OR = 3.31, 95% CI = 2.05–5.35, p < 0.001) in the vaccine and control groups, respectively. Headache and myalgia were more frequent in the newly licensed vaccines (OR = 1.97, 95% CI = 1.28–3.06, p = 0.02 and OR = 3.31, 95% CI = 2.05–5.35, p < 0.001) and younger adults (OR = 1.40, 95% CI = 1.12–1.75, p = 0.003 and OR = 1.54, 95% CI = 1.20–1.96, p < 0.001). In four open-label trials, the incidences of headache, myalgia, and unsolicited NMAEs were 38.7%, 27.4%, and 1.5%. Following vaccination in phase 3 trials, headache and myalgia were still common with a rate of 29.5% and 19.2%, although the unsolicited NMAEs with incidence rates of ≤ 0.7% were not different from the control group in each study. Conclusions: Following the vaccination, NMAEs are common of which headache and myalgia comprised a considerable measure, although life-threatening unsolicited events are rare. NMAEs should be continuously monitored during the ongoing global COVID-19 vaccination program.

Background. Patients with psoriasis need long-term medication to control their condition. Recent studies suggest that changing the intestinal flora may be a potential treatment. Methods. The databases were utilized to search the randomized controlled trials (RCTs) and preclinical trials about probiotic supplement in the treatment of psoriasis. The retrieval time is from the establishment of these databases to December 2020. RevMan5.3 was used for the risk assessment of bias and meta-analysis. This systematic review was registered in PROSPERO (CRD42021232756). Results. A total of 3 RCTs involving 164 participants were included. Two RCTs showed that probiotics can improve PASI and thereby improve the condition. For inflammation-related indicators, only one RCT showed that probiotics can improve the levels of CRP and TNF-α but have no obvious improvement effect on IL6. One RCT demonstrated the total effective rate of probiotics in the treatment of psoriasis. For adverse events, one RCT showed that the incidence of adverse events of probiotic treatment was low. Preclinical studies showed that continuous intervention with oral probiotics can significantly improve the progression of psoriasis and reduce the expression of inflammatory factors. The meta-analysis showed that the PASI between two groups was of no statistical significance (SMD 1.83 [-0.41, 4.07], P = 0.11 ). Meanwhile, probiotics may improve skin thickness (SMD -5.87 [-11.34, -0.41], P = 0.04 ) in animal model. Conclusion. Prebiotics may have a positive effect on alleviating the clinical symptoms of psoriasis, but a large sample of RCTs is still needed to support its therapeutic effect in psoriasis.
