Vitamin D and Cutaneous Melanoma Risk: An Umbrella Review of Systematic Reviews and Meta-Analyses.

Background: Vitamin D (VitD) properties can impact cancer cells. Despite the documented link between VitD levels and prevalence of several cancer types, conflicting findings have been reported for cutaneous melanoma (CM). Objective: This overview aims to compile the evidence from existing systematic reviews and meta-analyses, emphasizing the relationships between VitD serum levels, intake, receptor (VDR) gene polymorphisms, and CM risk. Methods: A literature search in electronic databases was conducted, based on certain inclusion criteria. Results: Twenty-one studies were included. Conflicting evidence between high VitD serum levels, dietary/supplementary intake, and CM risk is highlighted. VDR polymorphisms may play a role in the intricate CM pathogenesis. Also, high serum levels of VitD are associated with improved CM prognosis. Conclusions: This overview showed that the impact of VitD on CM is not clear, and thus further research is suggested to explore its true effect size on CM risk.

Chinese herbal medicine Ginkgo biloba L. preparations for ischemic stroke: An overview of systematic reviews and meta-analyses.

BACKGROUND: Ginkgo biloba L. preparations (GBLPs) are a class of Chinese herbal medicine used in the adjuvant treatment of ischemic stroke (IS). Recently, several systematic reviews (SRs) and meta-analyses (MAs) of GBLPs for IS have been published. OBJECTIVE: This overview aims to assess the quality of related SRs and MAs. SEARCH STRATEGY: PubMed, Embase, Cochrane Library, Web of Science, Chinese Biological Medicine, China National Knowledge Infrastructure, Wanfang, and Chinese Science and Technology Journals databases were searched from their inception to December 31, 2022. INCLUSION CRITERIA: SRs and MAs of randomized controlled trials (RCTs) that explored the efficacy of GBLPs for patients with IS were included. DATA EXTRACTION AND ANALYSIS: Two independent reviewers extracted data and assessed the methodological quality, risk of bias (ROB), reporting quality, and credibility of evidence of the included SRs and MAs using A Measurement Tool to Assess Systematic Reviews 2 (AMSTAR 2), Risk of Bias in Systematic Reviews (ROBIS), the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA), and the Grading of Recommendations Assessment, Development and Evaluation (GRADE), respectively. Additionally, descriptive analysis and data synthesis were conducted. RESULTS: Twenty-nine SRs/MAs involving 119 outcomes were included in this review. The overall methodological quality of all SRs/MAs was critically low based on AMSTAR 2, and 28 had a high ROB based on the ROBIS. According to the PRISMA statement, the reporting items of the included SRs/MAs are relatively complete. The results based on GRADE showed that of the 119 outcomes, 8 were rated as moderate quality, 24 as low quality, and 87 as very low quality. Based on the data synthesis, GBLPs used in conjunction with conventional treatment were superior to conventional treatment alone for decreasing neurological function scores. CONCLUSION: GBLPs can be considered a beneficial supplemental therapy for IS. However, because of the low quality of the existing evidence, high-quality RCTs and SRs/MAs are warranted to further evaluate the benefits of GBLPs for treating IS.

How can clinicians enhance self-efficacy beliefs in osteoarthritis? An overview of systematic reviews with meta-analysis.

This overview of reviews aimed to synthesize the effectiveness of non-pharmacological approaches to enhance self-efficacy in people with osteoarthritis. The CINAHL, Embase, PsycINFO, PubMed, SPORTDiscus, and the Cochrane Library databases were searched from inception to December 2023. We considered systematic reviews with meta-analysis of randomized clinical trials evaluating any non-pharmacological intervention. We used AMSTAR 2 to assess the methodological quality of reviews. The overlap between reviews was calculated. We included eight systematic reviews with meta-analysis evaluating 30 different clinical trials. Overall, mind-body exercises, psychological interventions, and self-management strategies may improve arthritis self-efficacy. Specifically, the meta-analyses showed tai chi exercises, coping skills training, and the arthritis self-management program are more effective than controls to enhance arthritis self-efficacy in people with hip and/or knee osteoarthritis. In addition, inconsistent results were detected across meta-analyses regarding the effectiveness of multidisciplinary interventions. Finally, the degree of overlap between all reviews was moderate (CCA = 6%) and many included reviews reported most of the items of AMSTAR 2. Tai chi exercises, coping skills training, and the arthritis self-management program may be beneficial for enhancing arthritis self-efficacy.

Efficacy and Safety of Huachansu as an Adjuvant Therapy for Non-Small Cell Lung Cancer: An Overview of Systematic Reviews and Meta-Analyses.

OBJECTIVE: The purpose of this overview is to assess systematic reviews (SRs)/ meta-analyses (MAs) of Huachansu (HCS) combination chemotherapy for treating non-small cell lung cancer (NSCLC) and provide summarized evidence for clinical decision making. METHODS: From the creation of the database to JUNE 2023, 8 databases in English and Chinese were searched. SRs/MAs that met the inclusion and exclusion criteria were included. Two reviewers independently screened research, extracted data and assessed methodological quality, risk of bias, report quality and evidence quality by using relevant criteria from AMSTAR-2, ROBIS scale, PRISMA, and GRADE system. RESULTS: The short-term effect, long-term effect, quality of life improvement, safety and pain relief effect in 8 included SRs/MAs were assessed in this overview according to quantitative synthesis. Results assessed by AMSTAR-2, PRISMA, and ROBIS were generally unsatisfactory, with the results of the AMSTAR-2 assessment showing that all of them were of low or critically low quality; the number of items in the included research that were fully reported (compliance was 100%) by the PRISMA checklist was only 50%, while there were 38.10% of the research reporting less than 60% completeness; the ROBIS assessment showed a small number of systems to be low risk of bias. In addition, 26 items were rated as moderate quality, while 50.94% of items were rated as low or critically low quality by GRADE. CONCLUSION: HCS may be a promising adjuvant therapy for NSCLC. However, high-quality SRs/MAs and randomized control trials (RCTs) should be conducted to provide sufficient evidence so as to draw a definitive conclusion.

Effects of acupuncture and moxibustion on ulcerative colitis: An overview of systematic reviews.

Ulcerative colitis (UC) is a gastrointestinal disease with an unknown etiology that severely affects patients' quality of life. Acupuncture and moxibustion therapies are effective in the treatment of UC, but existing systematic reviews (SRs) and meta-analyses (MAs) on this subject have variable methodological and outcome quality. Therefore, this study aimed to summarize and evaluate the evidence of existing SRs and MAs to provide more reliable evidence for clinical practice. Data were extracted from seven databases through systematic search and evaluated in terms of the methodological quality, reporting quality, risk of bias, and quality of evidence using the AMSTAR-2, PRISMA, ROBIS, and GRADE systems, respectively. Ten studies were finally included, and all of them showed many problems with the overall design and quality of outcomes. Because of the lack of high-quality evidence to support the findings from the existing studies, we should take this conclusion with caution and strictly implement the registration, design, and implementation of trials based on evidence to provide high-quality results in future studies.

Efficacy and safety of tongxinluo capsule for angina pectoris of coronary heart disease: an overview of systematic reviews and meta-analysis.

Background: Tongxinluo capsule (TXLC) is a common drug for treating angina pectoris of coronary heart disease (CHD). In recent years, many systematic reviews (SRs) and meta-analyses (MAs) have reported the efficacy and safety of TXLC for improving angina symptoms in patients with CHD. We aimed to comprehensively evaluate the existing SRs and MAs of TXLC in treating angina pectoris of CHD, summarize the evidence quality, and provide scientific evidence and recommendations. Methods: We searched seven databases for relevant SRs/MAs published up to 1 June 2023. Two reviewers independently completed the literature retrieval, screening, and data extraction. We used A Measurement Tool to Assess Systematic Reviews 2 (AMSTAR 2) to evaluate the methodological quality, the Risk of Bias in Systematic Reviews (ROBIS) to assess the risk of bias, and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) to determine the strength of the evidence. RevMan 5.3 was used to synthesize data. Results: We identified 15 SRs/MAs, including 329 RCTs and 33,417 patients. According to the evaluation results of AMSTAR-2, only one SR was of high methodological quality, the others were very low. ROBIS assessment showed that one SR (6.67%) had a low risk, 3 SRs (20%) had an unclear risk, and 11 SRs (73.33%) had a high risk. We assessed 42 outcomes by the GRADE, 10 (23.81%) for moderate-quality evidence, 17 (40.48%) for low-quality evidence, and 15 (35.71%) for very-low-quality evidence. Mate-analysis showed that TXLC combined with conventional western medications improved electrocardiogram efficacy (RR = 1.38, 95% CI: 1.23-1.43, P < 0.001) and angina efficacy (OR = 3.58, 95% CI: 3.02-4.24, P < 0.001), reduced angina attack frequency (SMD = -0.54, 95% CI: -0.64 to -0.44, P < 0.001) and angina duration (SMD = -0.42, 95% CI: -0.57 to -0.28, P < 0.001), with general heterogeneity. The pooled results showed that TXLC appears to have some efficacy in improving cardiac function and relieving angina symptoms, but there is limited evidence that it improves cardiovascular event rates, hemorheology, lipids, or hs-CRP. In the assessment of drug safety, TXLC was associated with different degrees of adverse drug reactions. Conclusion: Based on the evidence, TXLC may be effective as an adjuvant treatment for angina pectoris of CHD. However, the quality of the evidence is low, and the drug's safety must be carefully interpreted. In future studies, high-quality randomized controlled trials are needed to confirm the effectiveness and safety of TXLC.

Efficacy and Safety of Traditional Chinese Medicines as a Complementary Therapy Combined With Chemotherapy in the Treatment of Gastric Cancer: An Overview of Systematic Reviews and Meta-Analyses.

BACKGROUND: In China, traditional Chinese medicines (TCMs), as a complementary therapy combined with chemotherapy, is widely used in the treatment of gastric cancer (GC). In order to systematically evaluate and synthesize existing evidence to provide a scientific basis for the efficacy and safety of this complementary therapy, we present an overview of systematic reviews (SRs) and meta-analyses (MAs) on the topic of TCMs as a complementary therapy in combination with chemotherapy for the treatment of GC. METHODS: SRs/MAs on TCMs combined with chemotherapy for GC were comprehensively searched in 8 databases. Methodological quality, risk of bias, reporting quality, and quality of evidence were assessed using the Assessment of Multiple Systematic Reviews 2 (AMSTAR-2), the Risk of Bias in Systematic (ROBIS) scale, the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 (PRISMA 2020), as well as the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system. RESULTS: Thirteen published SRs/MAs were included in our study. In terms of methodology, all SRs/MAs were considered to be of very low quality. Only 3 SRs/MAs has been assessed as low risk of bias. None of the SRs/MAs has been fully reported on the checklist. A total of 97 outcome indicators extracted from the included SRs/MAs were evaluated, and only 1 item was assessed as high quality. CONCLUSIONS: TCMs may be an effective and safe complementary therapy in combination with chemotherapy for the treatment of GC. However, this conclusion must be treated with caution as the quality of the evidence provided by SRs/MAs is generally low.

Efficacy and safety of Shenqi Fuzheng injection combined with chemotherapy for cancer: An overview of systematic reviews.

BACKGROUND: In China, Shenqi Fuzheng injection (SFI) has been used as an adjuvant therapy to treat all kinds of cancer for many years. A large number of systematic reviews or meta-analyses (SRs/MAs) were published to assess its efficacy and safety in the past few years. However, the quality of SRs/MAs was unclear and did not generate high-quality clinical evidence. OBJECTIVE: We conducted an overview to integrate relevant SRs/MAs published in the past with the aim of providing new clinical evidence for SFI in combination with chemotherapy in the treatment of cancer. OBJECTIVE: We conducted an overview to integrate relevant SRs/MAs published in the past with the aim of providing new clinical evidence for SFI in combination with chemotherapy in the treatment of cancer. METHODS: A comprehensive search of PubMed, Web of Science, Embase, the Cochrane Library, CNKI, VIP, WanFang, and CBM was performed from the database inception to September 30, 2023. SRs/MAs of randomized controlled trials (RCTs) on SFI combined with chemotherapy for cancer were included. Four reviewers screened the literature and extracted relevant information. Five reviewers assessed the quality of reporting, methodological quality, risk of bias, and quality of evidence for SRs/MAs. We used corrected covered area (CCA) to assess the degree of overlap among the RCTs included in SRs/MAs. We performed a descriptive analysis for the results of the included SRs/MAs. RESULTS: A total of 32 SRs/MAs of SFI combined with chemotherapy for cancer were included. We assessed the reporting quality of SRs/MAs using the PRISMA 2020 statement. 1 SR/MA had relatively complete reports, 20 SRs/MAs had some deficiencies in reporting, and 11 SRs/MAs had serious deficiencies in reporting. We assessed the methodological quality of SRs/MAs using the AMSTAR 2 tool. The methodological quality of all SRs/MAs was very low. We assessed the risk of bias for SRs/MAs using the ROBIS tool. The risk of bias was low for 19 SRs/MAs and unclear for 13 SRs/MAs. We assessed the quality of evidence for SRs/MAs using the GRADE evidence quality evaluation system. 50 items were moderate quality, 46 items were low quality, 27 items were very low quality, and 85 items were unclear. SFI combined with chemotherapy played a role in increasing efficacy and decreasing toxicities in all kinds of cancer, including clinical efficacy (except liver cancer), quality of life, immune function (except CD8+), leukopenia, thrombocytopenia, hemoglobinopenia, nausea and vomiting, liver damage, kidney damage, neurotoxicity, alopecia, and diarrhea. CONCLUSION: The overview showed that SFI combined with chemotherapy may improve clinical efficacy (except for liver cancer), quality of life, and immune (except for CD8+) function in all types of cancer, as well as adverse events (AEs) such as leukopenia, thrombocytopenia, etc. Since most of the clinical evidence was low, higher quality clinical trials will be expected to improve the reliability of the above conclusions in the future.

Acupuncture for post-stroke spasticity: An overview of systematic reviews.

BACKGROUND: Post-stroke spasticity (PSS) is the most common complication of stroke. Acupuncture is widely used in clinical practice for the treatment of PSS, and is therefore considered a common complementary treatment. Several systematic reviews (SRs) and meta-analyses (MAs) have demonstrated the efficacy and safety of acupuncture in the treatment of PSS; however, the quality of evidence of these studies has not been adequately assessed. OBJECTIVE: To evaluate and summarize the SRs/MAs and inform future research and clinical practice on the efficacy and safety of acupuncture for PSS. DATA SOURCES AND EXTRACION: The following databases were searched from their dates of inception to March 26, 2023: PubMed, Embase, The Cochrane Library, Chinese National Knowledge Infrastructure (CNKI), Wanfang Database, SinoMed, and Chinese Science and Technology Periodical Database (VIP), and grey literature were manually searched. Two reviewers independently completed literature retrieval, screening, and data extraction. REVIEW APPRAISAL: Systematic evaluation tools to Assess Systematic Reviews (AMSTAR) 2, Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA 2020 Checklist), and the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system were used to systematically evaluate the methodological, reporting, and evidence quality of the SRs/MAs. RESULTS: Overall, 226 papers were examined, and after careful consideration, 10 SRs/MAs were deemed eligible for inclusion. The AMSTAR 2 assessment revealed that one SR/MA had medium, one study had low, and the remaining eight studies had critically low methodological qualities. Additionally, four SRs/MAs completed more than 60 % of the PRISMA 2020 checklist. The GRADE system indicated that six outcomes were medium, 26 outcomes were low, and 24 outcomes were critically low. CONCLUSION: Based on the evidence, acupuncture may be a promising complementary treatment to improve post-stroke spasticity and quality of life. Further high-quality RCTs are needed in future studies to support the broader application of acupuncture for the treatment of PSS.

Acceptance and Commitment Therapy for Chronic Pain: An Overview of Systematic Reviews with Meta-Analysis of Randomized Clinical Trials.

This overview of reviews aimed to summarize the evidence from systematic reviews and meta-analyses of randomized clinical trials of the efficacy of acceptance and commitment therapy (ACT) for adults with chronic pain in relation to pain intensity, pain-related functioning, quality of life, and psychological factors. The Cumulative Index of Nursing and Allied Health Literature (CINAHL), Embase, PsycINFO, PubMed, and the Cochrane Library databases were searched from inception to July 2, 2023. AMSTAR 2 was used to assess the methodological quality of systematic reviews. The overlap among reviews was calculated. Nine reviews comprising 84 meta-analyses of interest were included. At post-treatment, some meta-analyses mainly showed that ACT can reduce depression symptoms, anxiety symptoms, psychological inflexibility, and pain catastrophizing; and can improve mindfulness, pain acceptance, and psychological flexibility. At three-month follow-up, ACT can reduce depression symptoms and psychological inflexibility, as well as improve pain-related functioning and psychological flexibility. At six-month follow-up, ACT can improve mindfulness, pain-related functioning, pain acceptance, psychological flexibility, and quality of life. At six-twelve-month follow-up, ACT can reduce pain catastrophizing and can improve pain-related functioning. Some methodological and clinical issues are identified in the reviews, such as a very high overlap between systematic reviews, the fact that the certainty of the evidence is often not rated and specific details needed to replicate the interventions reviewed are often not reported. Overall, however, randomized clinical trials and systematic reviews show that ACT can improve outcomes related to chronic pain (eg, pain-related functioning). Future systematic reviews should address the methodological and clinical concerns identified here to produce higher-quality findings. PERSPECTIVE: Despite certain methodological and clinical issues, randomized clinical trials and systematic reviews of ACT appear to show that it can improve outcomes related to chronic pain (eg, psychological factors).

Is functional electrical stimulation effective in improving walking in adults with lower limb impairment due to an upper motor neuron lesion? An umbrella review.

PURPOSE: To conduct an umbrella review of systematic reviews on functional electrical stimulation (FES) to improve walking in adults with an upper motor neuron lesion. METHODS: Five electronic databases were searched, focusing on the effect of FES on walking. The methodological quality of reviews was evaluated using AMSTAR2 and certainty of evidence was established through the GRADE approach. RESULTS: The methodological quality of the 24 eligible reviews (stroke, n = 16; spinal cord injury (SCI), n = 5; multiple sclerosis (MS); n = 2; mixed population, n = 1) ranged from critically low to high. Stroke reviews concluded that FES improved walking speed through an orthotic (immediate) effect and had a therapeutic benefit (i.e., over time) compared to usual care (low certainty evidence). There was low-to-moderate certainty evidence that FES was no better or worse than an Ankle Foot Orthosis regarding walking speed post 6 months. MS reviews concluded that FES had an orthotic but no therapeutic effect on walking. SCI reviews concluded that FES with or without treadmill training improved speed but combined with an orthosis was no better than orthosis alone. FES may improve quality of life and reduce falls in MS and stroke populations. CONCLUSION: FES has orthotic and therapeutic benefits. Certainty of evidence was low-to-moderate, mostly due to high risk of bias, low sample sizes, and wide variation in outcome measures. Future trials must be of higher quality, use agreed outcome measures, including measures other than walking speed, and examine the effects of FES for adults with cerebral palsy, traumatic and acquired brain injury, and Parkinson's disease.

Ferroptosis: A new view on the prevention and treatment of diabetic kidney disease with traditional Chinese medicine.

Diabetic kidney disease is one of the complications of diabetes mellitus, which can eventually progress to end-stage kidney disease. The increasing prevalence of diabetic kidney disease has brought huge economic burden to society and seriously jeopardized public health. Ferroptosis is an iron-dependent, non-apoptosis-regulated form of cell death. The regulation of ferroptosis involves different molecular mechanisms and multiple cellular metabolic pathways. In recent years, ferroptosis has been proved to be closely related to the occurrence and development of diabetic kidney disease, and can interact with pathological changes such as fibrosis, inflammation, oxidative stress, and disorders of glucose and lipid metabolism, destroying the structure, form and function of the inherent cells of the kidney, and promoting the progression of the disease. Traditional Chinese medicine has a long history of treating diabetic kidney disease with remarkable curative effect. Current scholars have shown that the oral administration of traditional Chinese medicine and the external treatment of Chinese medicine can regulate GPX4, Nrf2, ACSL4, PTGS2, TFR1 and other key signaling molecules, curb ferroptosis, and prevent the progressive deterioration of diabetic kidney disease. In this paper, the mechanism of ferroptosis and diabetic kidney disease and the prevention and treatment of traditional Chinese medicine are analyzed and summarized, in order to provide new ideas and new plans for the treatment of diabetic kidney disease.

Chemical Constituents， Pharmacological Effect， and Product Development of Eucommia ulmoides with Both Medicinal and Edible Values： A Review / 中国实验方剂学杂志

Eucommia ulmoides， a plant belonging to Eucommiaceae， has a history of medical use for over two thousand years in China. The dried bark and leaves of this plant are usually used as medicinal materials. Due to the high safety in clinical application， E. ulmoides leaves were officially recognized for both medicinal and edible use by the food safety evaluation in 2019， providing a valuable resource for the development of food and health products. According to the traditional Chinese medicine theory， E. ulmoides has the effects of nourishing the liver and kidneys， strengthening sinews and bones， and calming fetus. Modern research has shown that different parts such as the bark， leaves， flowers， and seeds of E. ulmoides contain similar chemical components， including phenylpropanoids， terpenoids， flavonoids， phenolic acids， steroids， and polysaccharides. E. ulmoides exhibits diverse pharmacological activities such as lowering blood pressure and blood lipid and glucose levels， preventing osteoporosis and possesses anti-tumor， anti-bacterial， antiviral， anti-inflammatory， antioxidant， and hepatoprotective effects. Therefore， it holds great potential for the development of products with both medicinal and edible values. This review systematically summarizes the chemical constituents， pharmacological activities， and representative medicinal and edible products of different parts of E. ulmoides. It is expected to provide theoretical references for the clinical application of E. ulmoides and its active components and the development and utilization of the products with both medicinal and edible values. This review contributes to a deeper understanding of the medicinal properties of E. ulmoides and provides guidance for further exploration of its applications in the healthcare field. As a plant with both medicinal and edible values， E. ulmoides is expected to attract more attention in future research and contribute to human health.

An overview of systematic reviews of acupuncture for neurodegenerative disease.

BACKGROUND: Acupuncture has been widely used in the treatment of neurodegenerative diseases and a large number of systematic reviews (SRs) have been published, but the results are controversial. Therefore, it is necessary to comprehensively summarize and objectively evaluate the clinical evidence of acupuncture for neurodegenerative diseases. OBJECTIVE: To evaluate the SRs that assess the efficacy and safety of acupuncture for neurodegenerative diseases. This overview is intended to provide evidence for clinical decision making by healthcare providers and policymakers and to provide evidence for clinical decision making by healthcare providers and policymakers and to provide recommendations for researchers to conduct high quality SRs and clinical studies. METHODS: We searched four Chinese databases (SinoMed, CNKI, Wanfang and VIP) and four international databases (Cochrane Library, Embase, PubMed and Web of Science) for SRs of acupuncture for neurodegenerative diseases. The search period ran from the beginning of the database to March 5, 2023. Literature screening and data extraction were performed independently by two individuals. Methodological quality, risk of bias and associated evidence levels were assessed for all SRs using AMSTER 2, ROBIS and GRADE tools. In addition, the RCT overlap between SRs was calculated by corrected coverage area (CCA). We also conducted quantitative synthesis or descriptive analysis of the relevant data. RESULTS: Finally, we identified 53 SRs (three were qualitative descriptions and fifty were meta-analyses). Under AMSTAR 2, only one SR was rated as moderate quality, six SRs as low quality and 46 SRs as very low quality. According to ROBIS, 33 SRs were rated as a high risk of bias and 20 as a low risk of bias. Cognitive functions in neurodegenerative diseases, activities of daily living and the motor and non-motor outcomes associated with PD were included to summary description. The pooled results show that acupuncture combined with conventional treatment may have an overall advantage over conventional treatment, but the quality of evidence is low. Specific adverse reactions/events were reported in 20 SRs. Common needle-related adverse events included pain, dizziness, bleeding, or subcutaneous hematoma. No severe adverse events were reported in any SRs. CONCLUSION: Evidence suggests that acupuncture is generally effective and relatively safe for cognitive function and activities of daily living in neurodegenerative diseases. In addition, acupuncture may have some benefits in improving motor and non-motor symptoms in patients with PD. However, high-quality RCTs and SRs are still needed to further clarify the efficacy and safety of acupuncture in treating neurodegenerative diseases.

Compound Kushen injection combined with transarterial chemoembolization for hepatocellular carcinoma: An evidence map and overview of systematic reviews.

ETHNOPHARMACOLOGICAL RELEVANCE: For the treatment of hepatocellular carcinoma (HCC), compound Kushen injection (CKi) is commonly used in combination with transarterial chemoembolization (TACE). AIMS OF THE STUDY: Our objective was to evaluate the reporting quality, methodological quality, risk of bias, and certainty of evidence for CKi combined with TACE for the treatment of patients with HCC by conducting systematic reviews (SRs). The purpose of this study was to improve the clinical application of CKis, strengthen clinical decision-making regarding CKis, and inform future research. MATERIALS AND METHODS: We used eight databases to systematically search SRs of CKi combined with TACE for HCC through February 21, 2023. The quality of reporting of SRs was evaluated using the 2009 Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, methodological quality using A MeaSurement Tool to Assess systematic Reviews 2, risk of bias using the Risk of Bias in Systematic Review, and certainty of evidence using the Grading of Recommendations Assessment. Finally, the assessment results were visualized by the evidence mapping method. This overview has been registered on PROSPERO with the registration title "Compound Kushen injection for hepatocellular carcinoma: An overview of systematic reviews" and registration number CRD42022369120. RESULTS: A total of 12 SRs meeting the inclusion criteria were included. In terms of reporting quality, 42% of SRs reported relatively complete reports and 58% had certain deficiencies. The methodological quality of all SRs was " critically low". The risk of bias was evaluated as low in 33% of SRs and high in 67% of SRs. The results of the evidence synthesis showed that, in the "moderate" level of evidence, CKi combined with TACE resulted in a 12.7%-21.5% benefit for one-year survival rate, 11.7%-17.2% benefit for objective response rate (ORR), 20.5%-27.1% benefit for quality of life, 22.2% benefit for nausea and vomiting, and 24.7%-27.4% benefit for leukopenia in HCC patients. CONCLUSION: In conclusion, CKi combined with TACE improved survival, ORR and quality of life in patients with HCC, and reduced adverse events. The results should be interpreted with caution due to the low methodological quality of the included SRs. The clinical efficacy of CKis must be confirmed in a large number of randomized controlled trials.

An Overview of Systematic Reviews and Meta-Analyses of Clinical Studies of Acupuncture for Cancer Pain.

BACKGROUND: Systematic reviews (SRs) and meta-analyses (MAs) for the use of acupuncture for cancer pain have been increasing, but the evidence has not been systematically and comprehensively assessed. We aimed to perform an overview of the evidence quality of SRs/MAs of acupuncture for improving cancer pain. METHODS: 8 databases were systematically searched to identify SRs/MAs of acupuncture for improving cancer pain. The A Measurement Tool to Assess Systematic Reviews 2 (AMSTAR-2), Risk of Bias in Systematic Reviews (ROBIS), Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), and Grades of Recommendations, Assessment, Development, and Evaluation (GRADE), respectively, were applied by 2 independent reviewers to evaluate the methodological quality, risk of bias, reporting quality, and evidence quality. RESULTS: A total of 14 SRs/MAs were included in the present study. By AMSTAR-2, two reviews were rated as having high methodological quality, while 12 were given a critically low rating. All SRs/MAs in Phase 1, Domain 1, and Domain 4, according to ROBIS, were at low risk. Furthermore, 4 reviews in Domain 2, twelve reviews in Domain 3, and ten SRs/MAs in Phase 3, were rated as having low risk of bias. With reporting quality, some reporting flaws were identified in the topic of protocol and registration, additional analyses, and search strategy. According to GRADE, the level of evidence quality was "critically low" to "moderate," and risk of bias was the most common downgraded factor. CONCLUSION: Acupuncture may be beneficial in improving cancer pain. However, due to the identified limitations and inconsistent findings, we recommend further rigorous, and more standardized SRs/MAs to provide strong evidence for definitive conclusions.

OBJECTIVES: To evaluate the report quality, methodological quality and evidence quality of the systematic reviews and meta-analyses (SRs/MAs) of acupuncture for in vitro fertilization-embryo transfer (IVF-ET). METHODS: The SRs/MAs of acupuncture for IVF-ET were searched electronically from databases of CNKI, Wanfang, VIP, SinoMed, PubMed, Embase, Cochrane Library, from inception of each database to September 27th, 2022. Two reviewers independently screened the literature and extracted the data. Using PRISMA statement, the AMSTAR 2 scale and the GRADE system, the report quality, methodological quality and evidence quality of the included SRs/MAs were assessed. RESULTS: A total of 28 SRs/MAs were included, with PRISMA scores ranging from 8.5 points to 27 points. The problems of report quality focused on protocol and registration, retrieval, risk of bias in studies, additional analysis, limitations and funding. The methodological quality of included studies was generally low, reflecting on items 2, 3, 7, 10, 12 and 16. A total of 85 outcome indexes were included in the GRADE system for evidence grade evaluation. Most of the evidences were low or very low in quality. The reasons for the downgrade were related to study limitations, inconsistency, imprecision and publication bias. CONCLUSIONS: Acupuncture therapy improves the outcomes of IVF-ET, but the methodological quality and evidence quality of related SRs/MAs are low. It is recommended to conduct more high-quality studies in the future to provide more reliable evidences.

Shenqi Fuzheng Injection Combined With Chemotherapy for Gastric Cancer: An Overview of Systematic Reviews and Meta-Analyses.

BACKGROUND: Gastric cancer (GC) is a prevalent malignant tumor of the digestive tract. Chemotherapy (CT) is the primary treatment for GC, but it is accompanied by toxic side effects. Several systematic reviews and meta-analyses (SRs/MAs) on the combination of Shenqi Fuzheng injection (SFI) with CT for GC have been published; however, the conclusions have been inconsistent. This overview of SRs/MAs aims to assess the effectiveness and safety of SFI for GC, establishing a dependable foundation for its clinical application. METHODS: We utilized 7 databases, namely PubMed, Embase, Cochrane Library, CNKI, Wanfang, VIP, and SinoMed, to conduct our search. The retrieval period spanned from inception to August 2023. The methodological quality, bias risk, reporting quality, and evidence quality of the SRs/MAs were assessed using the evaluation tools AMSTAR-2, ROBIS, PRISMA 2020, and GRADE, respectively. Subsequently, the randomized controlled trials (RCTs) included in the SRs/MAs were quantitatively analyzed through the implementation of RevMan 5.4 software. RESULTS: Eleven SRs/MAs were included in this study, comprising 54 RCTs involving a total of 9539 patients with GC. The studies covered the period from 2012 to 2021, with the number of original RCTs per study ranging from 3 to 20 and sample sizes ranging from 159 to 1413. The methodological quality of all 11 SRs/MAs was assessed as low or very low, and the quality of evidence was determined to range from moderate to very low. The comprehensive quantitative meta-analysis revealed that the combination of SFI with CT improved the objective response rate (ORR) (RR = 1.30, 95% CI = [1.21, 1.41], P < .00001) and disease control rate (DCR) (RR = 1.13, 95% CI = [1.09, 1.18], P < .00001) in GC patients, without heterogeneity observed among the studies. In comparison with CT alone, SFI combined with CT also demonstrated improvements in the Karnofsky performance status (KPS) (RR = 1.36, 95% CI = [1.25, 1.49], P < .00001) and CD4+/CD8+ level (RR = 1.16, 95% CI = [0.87, 1.46], P < .00001) of patients. In terms of adverse reactions, the combination therapy of SFI with CT was associated with a reduced incidence of gastrointestinal reactions (RR = 0.67, 95% CI = [0.58, 0.78], P < .00001) and neurotoxicity (RR = 0.64, 95% CI = [0.50, 0.81], P = .0002). CONCLUSIONS: SFI combined with CT can enhance the clinical effectiveness and enhance the quality of life in patients with GC, while minimizing adverse reactions. Nonetheless, the evaluation of overall quality remains deficient, thus restricting the reliability and stability of the conclusions. High-quality, large-sample RCTs remain crucial for establishing dependable clinical evidence. SYSTEMATIC REVIEW REGISTRATION: INPLASY20239004.

Quality of evidence supporting the role of acupuncture for breast cancer-related lymphoedema: an overview of systematic reviews and meta-analyses.

BACKGROUND: Breast cancer-related lymphedema (BCRL) may benefit from acupuncture as a therapeutic. However, the findings of systematic reviews (SRs) and meta-analyses (MAs) are inconsistent and their quality needs to be evaluated critically. We aimed to provide an overview of the methodological quality, risk of bias, quality of reporting, and quality of evidence for SRs/MAs of acupuncture for BCRL. METHODS: Publications were retrieved from four Chinese databases and four English databases. The methodological quality, risk of bias, reporting quality, and evidence quality of the included SRs/MAs were assessed by two independent researchers using the A Measurement Tool to Assess Systematic Reviews 2 (AMSTAR-2), Risk of Bias in Systematic Reviews (ROBIS), Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), and Grading of Recommendations, Assessment, Development and Evaluation (GRADE), respectively. RESULTS: There were a total of 8 SRs/MAs included. By AMSTAR-2, all SRs/MAs were graded as having low or very low methodological quality. By ROBIS, all SRs/MAs in phase 1, domain 1, and domain 4 of phase 2 were at low risk, while in domain 2 were at high risk. By PRISMA, reporting weaknesses in protocol and registration, as well as search method, were identified. By GRADE, the level of evidence quality was "low" to "very low", and the most commonly downgraded factor was the risk of bias. CONCLUSIONS: Acupuncture may be beneficial in improving BCRL. However, due to the identified limitations and conflicting findings, further more prescriptive and rigorous SRs/MAs are required to give strong evidence for final judgments.

An umbrella review of the evidence to guide decision-making in acupuncture therapies for chemotherapy-induced peripheral neuropathy.

BACKGROUND: Acupuncture therapy is believed to have therapeutic potential for patients suffering from chemotherapy-induced peripheral neuropathy (CIPN). This umbrella review aims to summarize and evaluate the evidence from current systematic reviews/meta-analyses (SRs/MAs) on the effectiveness of acupuncture treatment for CIPN. METHODS: We conducted a comprehensive search in eight electronic databases for SRs/MAs that included RCTs on acupuncture treatment for CIPN. Two separate researchers independently evaluated the methodological quality, reporting quality, and evidence quality of the SRs/MAs that were included in the study. Additionally, we examined the extent of overlap among the included RCTs by calculating the corrected covered area (CCA). Furthermore, we assessed the dependability of the effect sizes by conducting excess significance tests. We conducted a quantitative synthesis of all RCTs included in the SRs/MAs to obtain objective and updated conclusions. Furthermore, we also conducted an analysis of the acupuncture points used in RCTs. RESULTS: This umbrella review includes 9 SRs/MAs, and their methodological quality, risk of bias, reporting quality, and evidence quality were all deemed unsatisfactory. Out of the 9 SRs/MAs, 28 RCTs were included, with a total CCA of 25.4%, indicating a high degree of overlap. The test of super-significance did not yield any significant results. Our updated meta-analysis suggests that CIPN patients can benefit from acupuncture therapy, as indicated by effectiveness in measures including BPI-SF, VAS, FACT-NTX, NRS, SCV, and NCI-CTCAE. Egger's test and sensitivity analysis demonstrate the reliability and stability of this conclusion. The commonly used acupuncture points in the current RCTs include ST36, LI11, LI4, LR3, and SP6. CONCLUSION: Based on the existing evidence, acupuncture is effective and safe for patients with CIPN, as it can significantly improve effective rate, pain symptoms, quality of life, and nerve conduction velocity. However, given the low quality of current evidence, we should be cautious in interpreting this conclusion.
