Effect of Earthworm on Wound Healing: A Systematic Review and Meta-Analysis

Background: Earthworm, also called dilong (Chinese language), has been used as a traditional Chinese medicine for thousands of years. Recently, some scientists believe that earthworm extracts (EE) can promote wound healing. However, its effectiveness remains controversial. We conducted a meta-analysis to evaluate the effect of EE on wound healing based on the healing rate.Methods: We comprehensively reviewed literature that mentioned EE for wound healing in the PubMed, Cochrane Library, Embase, Web of Science, China National Knowledge Infrastructure (CNKI), VIP database for Chinese Technical Periodicals, and WanFang database that have been published until January 2021. We computed weighted mean difference (WMD) for analysis with RevMan 5.3 software in animal and human models groups. Two researchers independently selected studies and evaluated the risk of bias with the Cochrane Collaboration tool. The quality of the evidence was assessed with the Cochrane risk of bias tool. This study is registered on PROSPERO (CRD42020168400).Results: From 2,486 articles, we selected 16 studies for analysis. EE treatment was associated with improvements in wound healing performance based on wound healing rate (mouse model: weighted mean difference (WMD) = 3.55, 95% confidence interval (CI): 2.34–4.77, p < 0.00001; rat model: WMD = 17.29, 95% CI: 5.75–28.82, p = 0.003; rabbit model: WMD = 19.29, 95% CI: 9.95–28.64, p < 0.0001). Clinical studies also confirmed that EE could reduce healing time in hospital (WMD = −8.94, 95% CI: −17.75 to −0.14, p = 0.05).Conclusion: The results of this meta-analysis demonstrated the efficacy of EE on wound healing process. As a corollary, EE can be a useful natural product for wound healing drug development.Systematic Review Registration:https://www.crd.york.ac.uk/PROSPERO/display_record.php?RecordID=168400, identifier CRD42020168400.

Aims/Background: Ovariectomy (OVX)-induced murine model is widely used for postmenopausal osteoporosis study. Our current study was conducted to systematically review and essentially quantified the bone mass enhancing effect of puerarin on treating OVX-induced postmenopausal osteoporosis in murine model. Methods: Literatures from PUBMED, EMBASE, and CNKI were involved in our searching strategy by limited the inception date to January 9th, 2019. Moreover, the enhancing effect of puerarin on bone mass compared to OVX-induced rats is evaluated by four independent reviewers. Finally, all the data were extracted, quantified and analyzed via RevMan, besides that in our current review study, we assessed the methodological quality for each involved study. Results: Based on the searching strategy, eight randomization studies were finally included in current meta-analysis and systematic review. According to the data analysis by RevMan, puerarin could improve bone mineral density (BMD); (eight studies, n=203; weighted mean difference, 0.05; 95% CI, 0.03-0.07; P<0.0001) using a random-effects model. There is no significant difference between puerarin and estrogen (seven studies, n=184; weighted mean difference, 0.00; 95% CI, -0.01 to 0.00; P=0.30). Conclusions: Puerarin showed upregulating effects on bone mass in OVX-induced postmenopausal osteoporosis in murine model. More studies of the effect of puerarin on bone density in OVX animals are needed.

Objective: The amniotic membrane has biological properties that are beneficial to the wound healing process of diabetic foot ulcers (DFU). Our aim is to analyse the scientific evidence found in literature on the use of the amniotic membrane to stimulate DFU healing. Method: A systematic review of amniotic membrane's influence was undertaken, using the search terms ‘placenta’ ‘diabetic foot’ ‘amnion’ and biological dressing’, assessing the outcomes ‘wound healing’ and ‘wound healing time’, in DFU. Following the inclusion and exclusion criteria, randomised controlled trials (RCT) were identified, and the risk of bias was analysed according to the Cochrane risk of bias tool. We conducted a meta-analysis of the two outcomes to evaluate the level of evidence. Results: We identified six clinical trials, with a total of 331 patients. The most common risks of bias in the studies were selection, attrition, and detection biases. From the meta-analysis, the difference of the intervention group (amnion) in relation to the control group was statistically significant. We found that wound healing in the group treated with amniotic membrane occurs 2.32 times more often and is 32 days faster in comparison with the group that used conventional dressings. Conclusion: There is statistical evidence to support the effectiveness of amniotic membrane in comparison with other conventional dressings. In addition, there is a clear tendency for the use of amniotic membrane treatment to result in a larger number of DFUs healing at a quicker rate.

Background and purposeFlow arrest with balloon guide catheters (BGCs) is becoming increasingly recognized as critical to optimizing patient outcomes for mechanical thrombectomy. We performed a systematic review and meta-analysis of the literature for studies that compared angiographic and clinical outcomes for patients who underwent mechanical thrombectomy with and without BGCs.Materials and methodsIn April 2017 a literature search on BGC and mechanical thrombectomy for stroke was performed. All studies included patients treated with and without BGCs using modern techniques (ie, stent retrievers). Using random effects meta-analysis, we evaluated the following outcomes: first-pass recanalization, Thrombolysis In Cerebral Infarction (TICI) 3 recanalization, TICI 2b/3 recanalization, favorable outcome (modified Rankin Scale (mRS) 0–2), mortality, and mean number of passes and procedure time.ResultsFive non-randomized studies of 2022 patients were included (1083 BGC group and 939 non-BGC group). Compared with the non-BGC group, patients treated with BGCs had higher odds of first-pass recanalization (OR 2.05, 95% CI 1.65 to 2.55), TICI 3 (OR 2.13, 95% CI 1.43 to 3.17), TICI 2b/3 (OR 1.54, 95% CI 1.21 to 1.97), and mRS 0–2 (OR 1.84, 95% CI 1.52 to 2.22). BGC-treated patients also had lower odds of mortality (OR 0.52, 95% CI 0.37 to 0.73) compared with non-BGC patients. The mean number of passes was significantly lower for BGC-treated patients (weighted mean difference −0.34, 95% CI−0.47 to −0.22). Mean procedure time was also significantly shorter for BGC-treated patients (weighted mean difference −7.7 min, 95% CI−9.0to −6.4).ConclusionsNon-randomized studies suggest that BGC use during mechanical thrombectomy for acute ischemic stroke is associated with superior clinical and angiographic outcomes. Further randomized trials are needed to confirm the results of this study.

Background: The debate on the pros and cons of robot-assisted partial nephrectomy performed with (on-clamp) or without (off-clamp) renal artery clamping is ongoing. The aim of this meta-analysis is to summarize the available evidence on the comparative studies assessing the outcomes of these two approaches. Material and methods: A systematic review of the literature on PubMed, ScienceDirect®, and Embase® was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses Statement (PRISMA). Only comparative and case-control studies were submitted to full-text assessment and meta-analysis. RevMan 5.3 software was used. Results: From the initial retrieval of 1937 studies, 15 fulfilling inclusion criteria were selected and provided 2075 patients for analysis (702 off-clamp, 1373 on-clamp). Baseline tumor’s features showed a significant difference in size (weighted mean difference: –0.58 cm; 95% confidence interval: [–1.06, –0.10]; p = 0.02) and R.E.N.A.L. score (weighted mean difference: –0.53; 95% confidence interval: [–0.81, –0.25]; p = 0.0002), but not in the exophytic property, the location, and the PADUA score. Pooled analysis revealed shorter operative time (p = 0.02) and higher estimated blood loss (p = 0.0002) for the off-clamp group. Overall complication and transfusion rates were similar, while higher major complication rate was observed in the on-clamp approach (5.6% vs 1.9%, p = 0.03). No differences in oncological outcomes were found. Finally, functional outcomes (assessed by estimated glomerular filtration rate at early postoperative, 3 month, 6 month, and last available follow-up) were not statistically different. Conclusion: This meta-analysis shows that off-clamp robot-assisted partial nephrectomy is reserved to smaller renal masses. Under such conditions, no differences with the on-clamp approach emerged.

Abstract Background The literature showed that Grape Products Containing Polyphenols (GPCP) had anti-oxidant activity. However, the effects of GPCP on different biomarkers of oxidative stress are still controversial. In this regard, this systematic review and meta-analysis aimed to evaluate the effect of Grape Products Containing Polyphenols (GPCP) intake on oxidative stress markers. Methods PubMed, Scopus, Web of Science, and Google Scholar data bases were searched up to August 20, 2020. A random-effects model, weighted mean difference (WMD), and 95% confidence interval (CI) were applied for data analysis. Meta-analysis was conducted over 17 eligible RCTs with a total of 633 participants. The study registration number is CRD42019116696. Results A significant increase was observed in Total Antioxidant Capacity (TAC) (weighted mean difference (WMD) = 1.524 mmol/L, 95% confidence interval (CI): 0.83, 2.21). Intake of GPCP enhanced Superoxide Dismutase (SOD) (WMD = 0.450 mmol/L, 95% CI: 0.23, 0.66), TAC (WMD = 2.829 mmol/L, 95% CI: 0.13, 5.52), and Oxygen Radical Absorbance Capacity (ORAC) (WMD = 0.524 μmol/L, 95% CI: 0.42, 0.62) among healthy participants. Higher GPCP doses increased SOD (WMD = 0.539 U/mgHb, 95% CI: 0.24, 0.82) and ORAC (WMD = 0.377 μmol/L, 95% CI: 0.08, 0.67), whereas longer intervention periods enhanced ORAC (WMD = 0.543 μmol/L, 95% CI: 0.43, 0.64). Conclusion GPCP intake may partly improve status of oxidative stress, but further well-designed trials are required to confirm these results.

The meta-analysis presented in this article covered the efficacy of red clover isoflavones in relieving hot flushes and menopausal symptoms in perimenopausal and postmenopausal women. Studies were identified by MEDLINE (PubMed), Embase, and the Cochrane Library searches. The quality of the studies was evaluated according to Cochrane criteria. A meta-analysis of eight trials (ten comparisons) demonstrated a statistically significant reduction in the daily incidence of hot flushes in women receiving red clover compared to those receiving placebo: weighted mean difference (WMD—weighted mean difference) −1.73 hot flushes per day, 95% CI (confidence interval) −3.28 to −0.18; p = 0.0292. Due to 87.34% homogeneity, the performed analysis showed substantive difference in comparisons of postmenopausal women with ≥5 hot flushes per day, when the follow-up period was 12 weeks, with an isoflavone dose of ≥80 mg/day, and when the formulations contained a higher proportion of biochanin A. The meta-analysis of included studies assessing the effect of red clover isoflavone extract on menopausal symptoms showed a statistically moderate relationship with the reduction in the daily frequency of hot flushes. However, further well-designed studies are required to confirm the present findings and to finally determine the effects of red clover on the relief of flushing episodes.

Cancer Related Fatigue

BACKGROUND Background: Current guidelines have different recommendations on applying pharmacological interventions for managing cancer-related fatigue (CRF) among cancer survivors. OBJECTIVE Objective: This systematic review aims to synthesize clinical evidence on pharmacological interventions for managing CRF. METHODS Methods: Five databases were searched for potential Randomized controlled trials (RCTs) from their inception till October 2020. RCTs assessing the effect of pharmacological treatments for CRF among cancer survivors were considered eligible. Clinical significance was determined by comparing the estimated effect with that of minimal important difference (MID). The risk of bias of included RCTs were appraised using the Cochrane risk of bias tool for randomized trials 2. RESULTS Results: A total of 15 RCTs (1238 participants) were included. Majority presented some concerns of bias arising from the randomization process and selection of the reported result. Meta-analysis showed that psychostimulant and wakefulness agents had statistically significant while clinical insignificant effect on the treatment of CRF (pooled weighted mean difference (WMD): 2.8, 95% confidence interval (CI): 0.2 to 5.4, I2: 0%, 3 RCTs, MID: 3.0 to 6.0). Three natural products, including Renshen Yangrong Tang (mean difference (MD): -16.1, 95% CI: -8.9 to -23.3, MID: -17.3 to -11.4), Tualang honey (MD: 11.2, 95% CI: 7.1 to 15.3, MID: 3.0 to 6.0) and Shenmai injection plus Peptisorb (MD: -1.6, 95% CI: -2.1 to -1.1, MID: -1.1 to -0.8) demonstrated statistically and clinically significant effect in reducing CRF. CONCLUSIONS Conclusions: Existing evidence showed promising effects of three natural products in reducing CRF among cancer survivors. The results from this study need to be further confirmed with well-designed and adequate powered RCTs that use validated instruments for the measurement of CRF. CLINICALTRIAL The protocol of this systematic review has been registered in PROSPERO (registration number: CRD42018102347).

Background. Osteoporosis is a major disease that affects the quality of life of middle-aged and old people, so it is very important to find efficient and safe drugs to treat osteoporosis. The purpose of this study was to investigate the therapeutic effect of naringin on postmenopausal osteoporosis in ovariectomized (OVX) rats. Methods. Chinese biomedical databases, CNKI, PubMed, EMBASE, and Wan Fang were searched for articles from inception to March 2020. Two independent researchers screened articles according to inclusion criteria. RevMan 5.3 was used for data analysis. Results. Ten studies were included in the systematic review. The bone mineral density (BMD) significantly increased after naringin treatment (weighted mean difference, 0.06; 95% CI, 0.03–0.09; P < 0.01). There was no significant increase in BMD after estrogen treatment compared with naringin (weighted mean difference, 0.00; 95% CI, −0.00 to 0.01; P = 0.06). The trabecular bone volume (BV/TV) (weighted mean difference, 2.09; 95% CI, 1.85–2.34; P < 0.01) and trabecular thickness (Tb.Th) (weighted mean difference, 6.65; 95% CI, 6.55–6.74; P < 0.01) significantly increased after using naringin. Conclusions. Naringin had been shown to promote bone formation in OVX rats. However, the mechanism of naringin needs more research to confirm.

AbstractAimThe Coronavirus disease 2019 (COVID-19) outbreak is a major threat to human beings. Lung injury has been reported as the major outcome of COVID-19 infection. However, liver damage has also been considered to occur in severe cases. Current meta-analysis of retrospective studies was done to summarize available findings on the association between liver injury and severity of COVID-19 infection.MethodsOnline databases including PubMed, Scopus, Web of Science and Cochrane Library were searched to detect relevant publications up to 1 April 2020, using relevant keywords. To pool data, a fixed- or random-effects model was used depending on the heterogeneity between studies. Furthermore, publication bias test and sensitivity analysis were also done.ResultsIn total, 20 retrospective studies with 3,428 COVID-19 infected patients (severe cases = 1,455 and mild cases = 1,973), were included in this meta-analysis. Higher serum levels of Aspartate aminotransferase (weighted mean difference = 8.84 U/L, 95% CI = 5.97 to 11.71, P<0.001), Alanine aminotransferase (weighted mean difference = 7.35 U/L, 95% CI = 4.77 to 9.93, P<0.001), total Bilirubin (weighted mean difference = 2.30 mmol/L, 95% CI = 1.24 to 3.36, P<0.001) and lower serum levels of Albumin (weighted mean difference = −4.24 g/L, 95% CI = −6.20 to −2.28, P<0.001), were associated with a significant increase in the severity of COVID-19 infection.ConclusionsThe incidence of liver injury seems to be higher in patients with severe COVID-19 infection. This finding could help physicians to identify patients with poor prognosis at an early stage.
