Background To systematically collect, evaluate, and synthesize evidence from randomized controlled trials (RCTs) supporting the use of electroacupuncture (EA) as an additional treatment option for Vascular mild cognitive impairment (VaMCI), a meta-analysis was carried out. Methods Electronic searches of eight databases were used to locate RCTs that evaluated EA as a VaMCI adjuvant therapy. The Cochrane Risk of bias was used to assess the included trials’ methodological quality. Review Manager 5.4 was used to analyze the data. Trial sequential analysis (TSA) was conducted with the trial sequential analysis program. Results There were 15 RCTs with 1033 subjects in them. Compared to conventional therapy (CT) alone, the Montreal Cognitive Assessment (SMD 0.72, 95 percent CI [0.55, 0.88]), Mini-mental State Examination (SMD 0.73, 95 percent CI [0.60, 0.87]), and activities of daily living (SMD 0.83, 95 percent CI [0.54, 1.12]) were significantly improved while EA was used in conjunction with CT. The current studies exceeded the required information size, according to trial sequential analysis (TSA), demonstrating the reliability of EA adjuvant therapy VaMCI. Conclusions According to the pooled data, EA as an adjunct therapy for the treatment of VaMCI increases clinical efficacy. Although the TSA confirms a stable conclusion, it is encouraged to conduct studies of the highest quality standards.

Introduction Epidural analgesia (EA) is the most widely used intervention for the reduction of labor pain; however, it is contra-indicated for patients with spinal deformity or allergy to anesthetics and may be refused by parturients. As a noninvasive and nonnarcotic analgesic intervention, transcutaneous electrical acupoint stimulation (TEAS) has gained increasing attention in recent years. Therefore, we performed a network meta-analysis to compare the efficacy and safety of TEAS and EA as measured by visual analog scale score, the failure rate of natural delivery, adverse events, and Apgar scores. Methods Relevant randomized controlled trials (RCTs) from four electronic databases (PubMed, EMBASE, Web of Science, and Cochrane CENTRAL) and clinical trials.gov were searched from inception until September 4, 2022. A random effects model was used during analysis, and outcomes were evaluated as standard mean difference (SMD), odds ratio (OR), and 95% confidence intervals (CrI) using STATA (version SE15.0), R (version 3.6.1), and ADDIS (version 1.16.8) software. Results Ten RCTs comprising 1214 parturients were identified by screening. Six RCTs compared TEAS and controls, three compared EA and controls, and one compared TEAS and EA. No heterogeneity was found within the four outcomes. There was no significant difference in any outcomes between interventions or control treatments in terms of SMD, OR, and CrI. Combined with the highest surface under the cumulative ranking curve score, TEAS demonstrated possible better effects in the aspects of analgesic efficacy and safety under certain circumstances. Conclusions TEAS may be a potential alternative for parturients as a simple, noninvasive, and non-pharmacological intervention compared with EA in terms of analgesic efficacy and safety for mothers and neonates.

Background: Ferric sodium ethylenediaminetetraacetate (NaFeEDTA) enhances iron absorption in the presence of phytate. However, the amount of NaFeEDTA that would have to be added to a complementary food to provide the necessary intake of iron for an infant or young child if NaFeEDTA were the sole iron fortificant exceeds the Acceptable Daily Intake (ADI) of EDTA for this age group. EDTA increases iron absorption at a molar ratio EDTA:iron of less than 1:1. Objective: To determine whether iron absorption is enhanced with a mixture of ferrous sulfate (FeSO₄) and NaFeEDTA. Methods: Two studies with a crossover design were conducted in separate groups of 14 and 15 children aged 24 to 31 months. A complementary food consisting of millet porridge with cabbage, tofu, and pork-filled wheat flour dumplings was fortified with 2 mg iron as either FeSO₄ or NaFeEDTA (study 1) or 4 mg iron as FeSO₄ or a mixture of 2 mg each of FeSO4 and NaFeEDTA (study 2). Iron absorption was determined based on erythrocyte incorporation of stable iron isotopes. Results: In study 1, the geometric mean (± SD) iron absorption was 8.0% (3.1, 20.8) and 9.2% (3.1, 27.0) from food fortified with FeSO₄ and NaFeEDTA, respectively. In study 2, iron absorption was significantly higher from food fortified with 4 mg iron as 1:1 mixture of FeSO₄/NaFeEDTA than from food fortified with FeSO₄; the geometric mean iron absorption was 6.4% (3.0, 13.5) and 4.1% (1.9, 8.9), respectively. Conclusions: The enhancing effect of EDTA on iron absorption is less strong in composite meals containing enhancers; nevertheless, the equal mixture of FeSO₄ and NaFeEDTA significantly enhanced iron absorption and can be a strategy to ensure adequate iron absorption from phytate-containing complementary foods.

Introduction: This overview of systematic reviews (SRs) systematically collected, evaluated, and combined the evidence for migraine treatment with transcranial magnetic stimulation (TMS). Methods: We conducted a systematic literature search in various databases, such as PubMed, The Cochrane Library, Web of Science, Embase, the China National Knowledge Infrastructure, Wanfang, VIP, and China Biomedical Literature. Two reviewers independently assessed the methodological quality, risk of bias, reporting quality, and strength of evidence of the included studies using AMSTAR-2, ROBIS, the PRISMA checklist, and the GRADE system. Results: We performed an overview of 7 relevant SRs, of which 4 were of moderate quality and 3 were of low quality according to AMSTAR 2. All SRs had low risk of bias in Phase 1 (Assessing relevance), Domain 1 (Study eligibility criteria), and Domain 4 (Synthesis and findings) as evaluated by ROBIS. In Domain 2 (Identification and selection of studies), 4 SRs (57.1%) had low risk of bias, while in Domain 3 (data collection and study appraisal) and Risk of Bias in the Review Phase 3, 4 SRs (57.1%) had low risk of bias. The PRISMA reporting standards were generally comprehensive, but some limitations were observed in the assessments, pooled results, evidence reliability, registration and protocols, and funding sources. The GRADE levels ranged from moderate to low, with 10 outcomes of moderate quality and 6 outcomes of low quality. The main reason for the low quality of evidence was the small sample size and high heterogeneity of the available studies. Conclusion: TMS may improve migraine severity and frequency, but the evidence is limited due to methodological flaws and heterogeneity. Future studies should standardize use, assess side effects, and compare with other treatments.

Background: Myopia is the most prevalent refractive error and a growing global health concern that significantly affects visual function. Researchers have recently emphasized considerably on the influence of lifestyle on myopia incidence and development. This study investigates the relationship between leisure sedentary behaviors (LSB)/physical activity (PA)/sleep traits and myopia. Methods: LSB, PA, and sleep trait-associated genetic variants were used as instrument variables in a Mendelian randomization (MR) study to examine their causal effects on myopia. Summary genome-wide association studies (GWASs) statistical data for LSB and PA were obtained from UK Biobank, and the data of sleep traits was obtained from UK Biobank, UK Biobank and 23andMe, and FinnGen. We used summary statistics data for myopia from MRC IEU. The MR analyses was performed using the inverse variance-weighted (IVW), MR-Egger, weighted median, and MR Pleiotropy RESidual Sum and Outlier methods. Results: Computer use was genetically predicted to increase the myopia risk [IVW odds ratio (OR) = 1.057; 95% confidence interval (CI), 1.038–1.078; P = 7.04 × 10^− 9]. The self-reported moderate-to-vigorous physical activity (MVPA) (IVW OR = 0.962; 95% CI, 0.932–0.993; P = 1.57 × 10^− 2) and television watching (IVW OR = 0.973; 95% CI, 0.961–0.985, P = 1.93 × 10^− 5) were significantly associated with a lower myopia risk. However, genetically predicted sleep traits or accelerometer-measured physical activity had no significant associations with myopia. Conclusion: Our results indicated that computer use is a risk factor for myopia, whereas television watching and MVPA may protect against myopia. These findings shed new light on possible strategies for reducing the prevalence of myopia.
