Meta-Analysis
OBJECTIVE
To assess the impact of low-dose aspirin (LDA) on obstetrical outcomes through a meta-analysis of placebo-controlled randomized controlled trials (RCTs).
METHODS
A systematic search of the PubMed, Cochrane Library, Web of Science and Embase databases from inception to January 2024 was conducted to identify studies exploring the role of aspirin on pregnancy, reporting obstetrical-related outcomes, including preterm birth (PTB, gestational age <37 weeks), small for gestational age (SGA), low birth weight (LBW, birthweight < 2500g), perinatal death (PND), admission to the neonatal intensive care unit (NICU), 5-min Apgar score < 7 and placental abruption. Relative risks (RRs) were estimated for the combined outcomes. Subgroup analyses were performed by risk for preeclampsia (PE), LDA dosage (<100 mg vs. ≥100 mg) and timing of onset (≤20 weeks vs. >20 weeks).
RESULTS
Forty-seven studies involving 59,124 participants were included. Compared with placebo, LDA had a more significant effect on low-risk events such as SGA, PTB and LBW. Specifically, LDA significantly reduced the risk of SGA (RR = 0.91, 95% CI: 0.87-0.95), PTB (RR = 0.93, 95% CI: 0.89-0.97) and LBW (RR = 0.94, 95% CI: 0.89-0.99). For high-risk events, LDA significantly lowered the risk of NICU admission (RR = 0.93, 95% CI: 0.87-0.99). On the other hand, LDA can significantly increase the risk of placental abruption (RR = 1.72, 95% CI: 1.23-2.43). Subgroup analyses showed that LDA significantly reduced the risk of SGA (RR = 0.86, 95% CI: 0.77-0.97), PTB (RR = 0.93, 95% CI: 0.88-0.98) and PND (RR = 0.65, 95% CI: 0.48-0.88) in pregnant women at high risk of PE, whereas in healthy pregnant women LDA did not significantly improve obstetrical outcomes, but instead significantly increased the risk of placental abruption (RR = 5.56, 95% CI: 1.92-16.11). In pregnant women at high risk of PE, LDA administered at doses ≥100 mg significantly reduced the risk of SGA (RR = 0.77, 95% CI: 0.66-0.91) and PTB (RR = 0.56, 95% CI: 0.32-0.97), but did not have a statistically significant effect on reducing the risk of NICU, PND and LBW. LDA started at ≤20 weeks significantly reduced the risk of SGA (RR = 0.76, 95% CI: 0.65-0.89) and PTB (RR = 0.56, 95% CI: 0.32-0.97).
CONCLUSIONS
To sum up, LDA significantly improved neonatal outcomes in pregnant women at high risk of PE without elevating the risk of placental abruption. These findings support LDA's clinical application in pregnant women, although further research is needed to refine dosage and timing recommendations.

Meta-Analysis
INTRODUCTION
Women at increased risk of developing pre-eclampsia are advised to take a daily low-dose of aspirin from 12 weeks of pregnancy to reduce their risks. Despite the well-established prophylactic effect of aspirin, adherence to this therapy is low. This systematic review aimed to summarise evidence on the barriers and facilitators of adherence to low-dose aspirin to inform intervention development to support decision making and persistence with aspirin use for pre-eclampsia prevention.
MATERIALS AND METHODS
A systematic review and meta-synthesis of qualitative research was co-produced by representatives from charities, and public, clinical and academic members. Eight electronic databases (MEDLINE, PsycINFO, CINAHL, Web of Science, Scopus, EMBASE, Prospero, OpenGrey), archives of charities and professional organisations were searched (between October and November 2023 and re-run in August 2023) using predefined search terms. Studies containing qualitative components related to barriers and facilitators of adherence to low-dose aspirin during pregnancy were included. Quality assessment was performed using the Critical Appraisal Skills Programme checklist for qualitative research. A combination of the COM-B framework with phases of adherence process as defined by international taxonomy was used as the coding framework. Co-production activities were facilitated by use of 'Zoom' and 'Linoit'.
RESULTS
From a total of 3377 papers identified through our searches, five published studies and one dissertation met our inclusion criteria. Studies were published from 2019 to 2022 covering research conducted in the USA, Canada, UK, Netherlands and Australia. Barriers and facilitators to adherence were mapped to six categories of the COM-B for three phases of adherence: initiation, implementation, and discontinuation. The discontinuation phase of adherence was only mentioned by one author. Four key themes were identified relating to pregnancy: 'Insufficient knowledge', 'Necessity concerns balance', 'Access to medicine', 'Social influences', and 'Lack of Habit'.
CONCLUSIONS
The COM-B framework allowed for detailed mapping of key factors shaping different phases of adherence in behavioural change terms and now provides a solid foundation for the development of a behavioural intervention. Although potential intervention elements could be suggested based on the results of this synthesis, additional co-production work is needed to define elements and plan for the delivery of the future intervention.

INTRODUCTION
Moyamoya disease (MMD) is an uncommon cause of stroke. Antiplatelet treatment is commonly prescribed for patients with MMD despite the lack of strong evidence supporting its efficacy. We conducted a systematic review to evaluate evidence of antiplatelet treatment and clinical outcomes among patients with MMD.
METHODS
A systematic literature search was performed to identify studies that evaluated the association between antiplatelet treatment and clinical outcomes, including ischemic stroke, hemorrhagic stroke, functional outcome, survival, and bypass patency, in patients with MMD. The following databases were searched: PubMed, Embase, Scopus, and the Cochrane Library, from the inception date to February 2022.
RESULTS
Eight studies were included in this systematic review. Six studies evaluated antiplatelet treatment and ischemic stroke. Most studies did not demonstrate a protective effect of antiplatelet treatment against ischemic stroke. Five studies evaluated antiplatelet treatment and hemorrhagic stroke. All of them did not demonstrate an increased risk of hemorrhagic stroke. One study found the benefit of antiplatelet treatment in terms of survival. Regarding the effect of antiplatelet treatment on functional outcome and patency of surgical bypass, the results were inconclusive.
CONCLUSION
Current evidence suggests that antiplatelet treatment in patients with MMD did not demonstrate a protective effect against ischemic stroke. However, antiplatelet treatment did not increase the risk of hemorrhagic stroke in patients with MMD. The well-designed randomized controlled trial should be highlighted.

Meta-Analysis
AIM
The efficacy and safety of bivalirudin when used concurrently with glycoprotein IIb/IIIa inhibitors (GPI) is uncertain. In this systematic review and meta-analysis, we aimed to evaluate the efficacy and safety of bivalirudin versus heparin in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI) and to explore the impact of differential use (greater and balanced) of GPI.
METHODS
Online databases were queried from inception to March 2023 to identify eight randomized controlled trials (n = 22,483) for inclusion. The primary outcomes included all-cause mortality, major bleeding, major adverse cardiovascular events (MACE), and net adverse clinical events (NACE). Secondary efficacy endpoints included cardiac death, reinfarction, stent thrombosis (ST), and stroke. Data were pooled using a random-effects model to derive risk ratios (RRs) and 95% confidence intervals (CIs).
RESULTS
When compared to heparin, bivalirudin was associated with a significant reduction in all-cause mortality (RR 0.83; 95% CI 0.72-0.97; P = 0.02), major bleeding (RR 0.73; 95% CI 0.57-0.93; P = 0.01), cardiac death (RR 0.79; 95% CI 0.66-0.94; P = 0.01), and NACE (RR 0.80; 95% CI 0.72-0.89; P < 0.0001). However, while the bivalirudin arm showed an increased likelihood of ST in the greater GPI subgroup (RR 1.70; 95% CI 1.13-2.56; P = 0.01), it was associated with a decreased likelihood of ST in the balanced GPI subgroup (RR 0.40; 95% CI 0.24-0.65; P = 0.0003).
CONCLUSION
Overall, our findings suggest that bivalirudin may be a more efficacious intervention than heparin for reducing certain adverse events in patients with STEMI undergoing primary PCI.

Meta-Analysis Comparative Study Review
BACKGROUND
Propofol and sevoflurane are two of the most commonly used anaesthetics for paediatric surgery. Data from some clinical trials suggest that postoperative pain incidence is lower when propofol is used for maintenance of anaesthesia compared with sevoflurane, although this is not clear.
METHODS
This meta-analysis compared postoperative pain following maintenance of anaesthesia with propofol or sevoflurane in paediatric surgeries. PubMed Medline, Embase, Scopus, Web of Science and Cochrane Library were searched for randomised controlled trials (RCTs) that compared postoperative pain between sevoflurane and propofol anaesthesia in children. After quality assessment, a meta-analysis was carried out using bias-adjusted inverse heterogeneity methods, heterogeneity using I and publication bias using Doi plots.
RESULTS
In total, 13 RCTs with 1174 children were included. The overall synthesis suggested nearly two-fold higher odds of overall postoperative pain in the sevoflurane group compared with the propofol group (odds ratio [OR] 1.88, 95% confidence interval [CI] 1.12-3.15, I=58.2%). Further, children in the sevoflurane group had higher odds of having higher pain scores (OR 3.18, 95% CI 1.83-5.53, I=20.9%), and a 60% increase in the odds of requiring postoperative rescue analgesia compared with propofol (OR 1.60, 95% CI 0.89-2.88, I=58.2%).
CONCLUSIONS
Children maintained on inhalational sevoflurane had higher odds of postoperative pain compared with those maintained on propofol. The results also suggest that sevoflurane is associated with higher odds of needing postoperative rescue analgesia compared with propofol.
REGISTRATION
The protocol for this systematic review and meta-analysis was registered on the International Prospective Register of Systematic Reviews (PROSPERO) with registration ID CRD42023445913.

Meta-Analysis
The article aimed to compare the efficiency and safety of aspirin with low-molecular-weight heparin (LMWH) for thromboprophylaxis in orthopaedic surgery patients. According to the inclusion and exclusion criteria, PubMed, Embase and Cochrane Library database were searched for studies comparing aspirin and LMWH in venous thromboembolism (VTE) prophylaxis until 25 April 2023. The outcome measures included deep venous thrombosis(DVT)/Pulmonary embolism(PE) events, major bleeding events, wound complications, wound infection and death. Six studies met the requirements of our meta-analysis, including 12 470 patients in the aspirin group and 10 857 patients in the LMWH group. The meta-analysis showed that results showed that LMWH was superior to aspirin in preventing VTE events (odds ratio (OR) 1.44, 95% CI 1.24-1.68, P < 0.00001), whereas there was no significant difference between them in bleeding events (OR 0.95, 95% CI 0.86-1.05, P = 0.33), wound complication (OR 0.58, 95% CI 0.28-1.17, P = 0.13), wound infection (OR 1.12, 95% CI 0.86-1.47, P = 0.39) and mortality (OR 1.04, 95% CI 0.70-1.55, P = 0.83). In addition, subgroup analysis showed that compared with aspirin, LMWH was more likely to reduce the incidence of DVT events in orthopaedic surgery patients (OR 1.59, 95% CI 1.33-1.91, P < 0.00001), whereas there was no advantage in reducing the incidence of PE events (OR 1.22, 95% CI 0.62-2.40, P = 0.56). Despite the similar safety profiles, this meta-analysis showed that LMWH was significantly superior to aspirin in thromboprophylaxis after orthopaedic surgery. LMWH was still the first-line drug for thrombosis prevention in patients who underwent major orthopaedic surgeries.

Meta-Analysis
BACKGROUND
Risk of recurrence after minor ischemic stroke is usually reported with transient ischemic attack. No previous meta-analysis has focused on minor ischemic stroke alone. The objective was to evaluate the pooled proportion of 90-day stroke recurrence for minor ischemic stroke, defined as a National Institutes of Health Stroke Scale severity score of ≤5.
METHODS AND RESULTS
Published papers found on PubMed from 2000 to January 12, 2021, reference lists of relevant articles, and experts in the field were involved in identifying relevant studies. Randomized controlled trials and observational studies describing minor stroke cohort with reported 90-day stroke recurrence were selected by 2 independent reviewers. Altogether 14 of 432 (3.2%) studies met inclusion criteria. Multilevel random-effects meta-analysis was performed. A total of 6 randomized controlled trials and 8 observational studies totaling 45 462 patients were included. The pooled 90-day stroke recurrence was 8.6% (95% CI, 6.5-10.7), reducing by 0.60% (95% CI, 0.09-1.1; =0.02) with each subsequent year of publication. Recurrence was lowest in dual antiplatelet trial arms (6.3%, 95% CI, 4.5-8.0) when compared with non-dual antiplatelet trial arms (7.2%, 95% CI, 4.7-9.6) and observational studies 10.6% (95% CI, 7.0-14.2). Age, hypertension, diabetes, ischemic heart disease, or known atrial fibrillation had no significant association with outcome. Defining minor stroke with a lower National Institutes of Health Stroke Scale threshold made no difference - score ≤3: 8.6% (95% CI, 6.0-11.1), score ≤4: 8.4% (95% CI, 6.1-10.6), as did excluding studies with n<500%-7.3% (95% CI, 5.5-9.0).
CONCLUSIONS
The risk of recurrence after minor ischemic stroke is declining over time but remains important.

Meta-Analysis
OBJECTIVE
This study aimed to assess the risks and benefits of reinitiating antiplatelet therapy after spontaneous intracerebral hemorrhage (ICH) through a systematic review and meta-analysis. The reinitiation of antiplatelet therapy is commonly used to reduce major vascular events in patients with occlusive vascular diseases, but its use in ICH patients may increase the risk of bleeding.
MATERIALS AND METHODS
A comprehensive search was conducted on databases including MEDLINE, Embase, Cochrane Library, clinicaltrials.gov, and the International Standard Randomized Controlled Trial Number Register (ISRCTN). Randomized controlled trials and cohort studies that investigated the use of reinitiation of antiplatelet therapy after hemorrhagic stroke were included. Data on ICH recurrence, major bleeding events, major occlusive cerebrovascular events, ischemic stroke, and all-cause mortality were extracted and analyzed using R software.
RESULTS
The study included a total of 10 studies with 6,340 participants. The control group consisted of 2,964 patients who did not receive antiplatelet therapy, while the study group included 1,285 patients who received antiplatelet therapy without restrictions on the specific drug type. The meta-analysis showed that antiplatelet therapy significantly reduced the risk of ICH recurrence (RR=0.72, 95% CI: 0.59, 0.87), had no significant impact on the risk of severe bleeding events (RR=0.93, 95% CI: 0.80, 1.08), significantly lowered the risk of major occlusive cerebrovascular events (RR=0.59, 95% CI: 0.46, 0.77), had no significant effect on the risk of ischemic stroke (RR=0.77, 95% CI: 0.53, 1.12), and did not significantly influence the risk of all-cause mortality (RR=0.75, 95% CI: 0.45, 1.15).
CONCLUSIONS
Based on the findings, reinitiating antiplatelet therapy after spontaneous ICH appears to be generally safe. However, the benefits in terms of reducing the risk of all-cause mortality are not evident and require confirmation through large-scale, long-term, prospective, randomized controlled trials.

Meta-Analysis
INTRODUCTION
Among different coronary stents implanted in High Bleeding Risk (HBR) patients with an indication for short antiplatelet therapy, no comparisons in terms of efficacy have been provided.
METHODS
A Network Meta Analysis was performed including all randomized controlled trials comparing different coronary stents evaluated in HBR patients. Major Adverse Cardiovascular Events (MACEs) as defined by each included trial were the primary end point, whereas TLR (target lesion revascularization), TVR (target vessel revascularization), stent thrombosis and total and major (BARC3-5) bleedings were the secondary ones.
RESULTS
A total of four studies (ONYX ONE, LEADERS FREE, SENIOR and HBR in BIO-RESORT) including 6637 patients were analyzed with different kind of stents and dual antiplatelet therapy (DAPT) length (1 or 6 months) on 12 months follow-up. About one-third of these patients were defined HBR due to indication for oral anticoagulation. All drug eluting stents (DESs) reduced risk of MACE compared to Bare Metal Stents (BMSs) when followed by a 1-month DAPT. At SUCRA analysis, Orsiro was the device with the highest probability of performing best. Rates of TLR and TVR were significantly lower when using Resolute Onyx, Synergy and BioFreedom stents in comparison to BMS when followed by 1-month DAPT, with Synergy ranking best. Synergy also showed a significantly lower number of stent thrombosis compared to BMS (RR 0.28, 95% CI 0.06-0.93), while Orsiro and Resolute Integrity showed the highest probability of performing best.
CONCLUSION
In HBRs patients, all DESs were superior to BMSs in terms of efficacy and safety. Among DESs, Orsiro was the one with the highest ranking in terms of MACE, mainly driven by a reduced incidence of repeated revascularization and stent thrombosis.

Meta-Analysis
Traditional chinese medicine injections with activating blood circulation, equivalent effect of anticoagulation or antiplatelet, for acute myocardial infarction: A systematic review and meta-analysis of randomized clinical trials.
BACKGROUND
Traditional Chinese medicine injection for Activating Blood Circulation (TCMi-ABC), which exhibits comparable anticoagulant and antiplatelet effects, is commonly used as an adjuvant treatment for acute myocardial infarction (AMI) in China.
OBJECTIVE
The aim of this study was to conduct a meta-analysis to assess the efficacy and safety of TCMi-ABC in combination with conventional western medicine in reducing mortality associated with AMI.
METHODS
We conducted a comprehensive search of PubMed, Cochrane Library, EMBASE, Web of Science, CBM, WanFang Data, and CNKI databases. Randomized controlled trials (RCTs) investigating the use of TCMi-ABC (including Danhong injection, sodium tanshinone IIA sulfonate injection, salvia miltiorrhiza ligupyrazine injection, and puerarin injection) for the treatment of AMI were included. The search included studies published from the inception of the databases up to December 2022. Two authors independently screened RCTs, extracted data, and assessed the risk of bias. Meta-analysis was performed using RevMan 5.3 and Stata 17.0. The quality of evidence was evaluated using the GRADE approach.
RESULTS
A total of 52 RCTs involving 5363 patients were included in the analysis, none of which described independent testing of the purity or potency of the TCMi-ABC product used. 19/52 reported random sequence generation. All RCTs lack adequate description of allocation concealment. 51/52 failed to assess blinding. The meta-analysis results demonstrated that the combined application of TCMi-ABC, compared with conventional western medicine treatment alone, significantly reduced in-hospital mortality in AMI patients [RR= 0.41, 95% CI (0.29, 0.59), P < 0.05], decreased the incidence of malignant arrhythmia [RR= 0.40, 95% CI (0.26, 0.61), P < 0.05], and increased left ventricular ejection fraction (LVEF) [MD= 5.53, 95% CI (3.81, 7.26), P < 0.05]. There was no significant difference in the incidence of adverse events between the two groups (P > 0.05). The GRADE evidence quality classification indicated that the evidence for in-hospital mortality, malignant arrhythmia, and adverse events was of moderate quality, while the evidence for LVEF was of low quality.
CONCLUSION
TCMi-ABC demonstrates additional clinical value in reducing mortality and the risk of malignant arrhythmia in patients with AMI. However, further validation of these findings is warranted through high-quality clinical trials due to methodological weaknesses in randomization, blinding, allocation concealment, and insufficient assessing for the purity/potency of herbs and the gram amount of active constituents.
