Background and Purpose. Mild cognitive impairment (MCI) is a common condition, which threatens the quality of life of older adults. Tai Chi (TC) is growing in popularity among patients with MCI. This study is aimed at evaluating the effectiveness and safety of TC in older adults with MCI. Design. Randomized controlled trials (RCTs) from multiple databases from inception to December 2020 published in English were searched. Two researchers independently performed eligible study screening and data extraction. The methodological quality was assessed with the Jadad score. Meta-analysis of RCTs on TC in the treatment of MCI was performed with RevMan Version 5.4.1. Results. Seven RCTs with 1265 participants were included. For most RCTs, the overall reporting of methodological quality was high. Results of the meta-analysis indicate that TC improved MCI patients’ cognitive function significantly, including overall cognitive function ( MD = − 2.24 , 95% CI -3.51 to -0.97, P = 0.0005 ), memory and learning ( SMD = 0.83 , 95% CI 0.22 to 1.45, P = 0.008 ), visuospatial ability ( MD = 3.15 , 95% CI 0.74 to 5.56, P = 0.01 ), executive functions ( MD = 0.32 , 95% CI 0.03 to 0.61, P = 0.03 ), and physical activity ( MD = 18.78 , 95% CI 10.80 to 26.76, P < 0.00001 ). However, no significant benefit was found for TC on psychological activity ( MD = 0.17 , 95% CI -0.62 to 0.96, P = 0.36 ) and biomarker improvement. Conclusion. The meta-analysis confirmed the clinical therapeutic effect of TC for MCI. More rigorous and long-term follow-up RCTs should be conducted in the future.
Background The world is currently struggling with the Coronavirus disease 2019 (COVID-19) pandemic. Dietary supplements (DSs) and herbal medicine provide a potentially convenient and accessible method for its recovery, but direct evidence is limited. Objective This study aims to investigate the effectiveness of DSs and herbs in patients with COVID-19. Methods A systematic literature search was conducted in multiple electronic English and Chinese databases. Randomized controlled trials (RCTs) involving DSs or herbal medicine interventions on patients with COVID-19 from November 2019 to February 2021 were included. Data was extracted, summarized and critically examined. Results Out of 9402 records identified in the initial search, twelve RCTs were included in this review. Risk of bias of these RCTs was deemed high. Most of the trials were of low methodologic quality. Nine studies showed herbal supplements were beneficial to the recovery of COVID-19 patients; zinc sulfate could shorten the duration of loss of smell but not total recovery from COVID-19. No severe adverse events were reported. Conclusion Herbal supplements may help patients with COVID-19, zinc sulfate is likely to shorten the duration of olfactory dysfunction. DS therapy and herbal medicine appear to be safe and effective adjuvant therapies for patients with COVID-19. These results must be interpreted with caution due to the overall low quality of the included trials. More well-designed RCTs are needed in the future.
Purpose. To evaluate the effectiveness and safety of acupoint catgut embedding therapy (ACET) in postmenopausal osteoporosis (PMOP). Methods. Review of some databases from their inception to June 2018 and randomized controlled trials (RCTs) in which ACET with PMOP were included. Two researchers extracted and evaluated the information independently. Cochrane Collaboration’s tool and Jadad scale were used to evaluate the quality of the studies. RevMan V.5.3.3 software was used to carry out the meta-analysis while trial sequential analysis (TSA) performed with TSA 0.9 software. Results. 12 RCTs with 876 participants were included in this review. Meta-analysis showed that ACET alone was not superior to medication in effectiveness rate (RR= 1.11; 95% CI (0.89, 1.40); P=0.35) and E2 (SMD= 0.20; 95% CI (-0.17, 0.57); P=0.28; I2=20%) while ACET combining medication was more effective on the effectiveness rate (RR= 1.32; 95% CI (1.20, 1.46); P<0.000 01) and E2 (SMD= 1.24; 95% CI (0.63, 1.84); P<0.0001). Additionally, ACET combining calcium could increase the bone mineral density (BMD) of the L2~4 vertebrae and femur-neck [WMDL2~4 = 0.03; 95% CI (0.01, 0.05); P=0.003; and WMDFemur-neck = 0.07; 95% CI (0.03, 0.10); P = 0.0006], reduce TCM syndrome score [WMD = -1.85; 95% CI (-2.13, -1.57); P<0.000 01], improve patient’s quality of life [WMDthree months = 6.90; 95% CI (3.90, 9.89); P<0.000 01; and WMDsix months = 12.34; 95% CI (5.09, 19.60); P=0.0009], and relieve pain [WMDVAS = -1.26; 95% CI (-1.66, -0.85); P<0.000 01; and WMDPain score = -2.59; 95% CI (-4.76, -0.43); P= 0.02]. The TSA showed that the effectiveness of ACET for PMOP was demonstrated accurately. Conclusions. ACET combining medication but not ACET alone is more effective than medication as comparison in the treatment of PMOP. As a novel treatment, ACET shows the potential of effectiveness and deserves further high quality of well-designed study.
BackgroundThe purpose of this study was to systematically evaluate the effectiveness of acupuncture combined with balloon dilatation in patients with post-stroke cricopharyngeal achalasia (CPA) according to the effective rate, videofluoroscopy swallowing study (VFSS) score and standardized swallowing function assessment scale (SSA) score through Meta-analysis.MethodsEnglish and Chinese language literature published before July 24,2022 were searched in ten electronic databases. The identified articles were screened, data were extracted, and the methodological quality of the included trials was assessed. Using RevMan 5.4.1 software to perform Meta-analysis.Results10 studies with 517 patients with post-stroke CPA were included. Meta-analysis showed that the effective rate of the experience group was higher than that of the control group [OR = 0.62; 95% CI (2.32, 13.05); I2 = 0%; p = 0.0001]. Compared to the control group, the SSA score was lower in the experience group [MD = −4.22; 95% CI (−4.57, −3.87); I2 = 42%; p < 0.00001]. In terms of VFSS scores, the experience group showed greater efficacy differences than control group [MD = 1.53; 95% CI (1.32, 1.75); I2 = 0%; p < 0.00001]. The subgroup analysis of VFSS score based on the average course of disease (<1 month vs. ≥1 month) showed no significant difference. The subgroup analysis based on average age (>60 years vs. ≤60 years) showed the VFSS score of the experience group was significantly higher than that of the control group, and the effect may be better in the subgroup older than 60 years. The subgroup analysis based on the treatment course (>30 days vs. ≤30 days) showed the VFSS score of the experience group was significantly higher than that of the control group, and the effect may be better in the subgroup the treatment course>30 days.ConclusionAcupuncture combined with balloon dilatation may be an effective method for treating post-stroke CPA. Compared with balloon dilatation, acupuncture combined with balloon can significantly improve the swallowing function of patients, and it is also effective for patients of different courses, ages, and treatment course, while patients over 60 years old and the treatment course over 30 days may have better clinical outcomes.
