Meta-Analysis
BACKGROUND
Short-term (≤6 months) dual antiplatelet therapy (DAPT) and DAPT de-escalation become attractive for patients with acute coronary syndrome.
METHODS
A systemic search identified randomized controlled trials that included patients with acute coronary syndrome treated using (1) standard DAPT (12 months) with clopidogrel, prasugrel (standard/low dose), or ticagrelor; (2) extended DAPT (≥18 months); (3) short-term DAPT (≤6 months) followed by P2Y inhibitor or aspirin; (4) 12-month DAPT with unguided de-escalation from potent P2Y inhibitors to low-dose potent P2Y inhibitor or clopidogrel at 1 month; and (5) guided selection DAPT with genotype or platelet function tests. The primary efficacy outcome (major adverse cardiovascular events) was a composite of cardiovascular death, myocardial infarction, or stroke. The primary safety outcome was major or minor bleeding.
RESULTS
This meta-analysis included 32 randomized controlled trials with 103 497 patients. While there were no differences in efficacy between short, unguided de-escalation and guided selection strategies, unguided de-escalation was associated with reduced risk of major adverse cardiovascular events compared with standard DAPT with clopidogrel or ticagrelor (hazard ratio [95% CI], 0.67 [0.49-0.93] and 0.68 [0.50-0.93]). Both short DAPT followed by P2Y inhibitor and unguided de-escalation were associated with reduced risks in safety compared with other strategies, including guided selection (hazard ratio [95% CI], 0.66 [0.47-0.93] and 0.48 [0.33-0.71]). Short DAPT followed by a P2Y inhibitor was associated with reduced risk of major bleeding and all-cause death compared with standard, extended DAPT (eg, versus DAPT with clopidogrel; hazard ratio [95% CI], 0.64 [0.42-0.97] and 0.60 [0.44-0.82]). By rankogram, unguided de-escalation strategy was the safest and most effective strategy in reducing major adverse cardiovascular events and major or minor bleeding while short DAPT followed by P2Y inhibitor was ranked the best for major bleeding and all-cause death.
CONCLUSIONS
In patients with acute coronary syndrome, unguided de-escalation was associated with the lowest risk of major adverse cardiovascular events and major or minor bleeding outcomes, while short DAPT followed by P2Y inhibitor was associated with the lowest risk of major bleeding and all-cause death.

Meta-Analysis
BACKGROUND
Recent studies have shown that aspirin consumption may reduce the risk of hepatocellular carcinoma (HCC), but their correlation is still not fully understood. This meta-analysis aimed to investigate the correlation between aspirin consumption and HCC.
METHODS
A systematic literature search was conducted on PubMed, Scopus, Cochrane Library, EMBASE, and Web of Science databases. The search period was from the establishment of the database to July 1, 2022 with no language restrictions.
RESULTS
A total of 19 studies including three prospective studies and 16 retrospective ones with 2,217,712 patients were included. Compared with those who did not take aspirin, those who took aspirin had a 30% lower risk of HCC (hazard ratio [HR] = 0.70, 95% confidence interval [CI] 0.63-0.76, I = 84.7%, P < 0.001). Subgroup analysis showed that aspirin significantly reduced the risk of HCC by 19% in Asia (HR = 0.81, 95% CI 0.80-0.82, I = 85.2%, P < 0.001) and by 33% (HR = 0.67, 95% CI 0.61-0.73, I = 43.6%, P = 0.150) in Europe and the U.S with no significant difference. Moreover, in patients with HBV or HCV infection, aspirin reduced 19% and 24% of the risk of HCC, respectively. However, aspirin administration might increase risks of gastrointestinal bleeding in patients with chronic liver disease (HR = 1.14, 95% CI 0.99-1.31, I = 0.0%, P = 0.712). Sensitivity analysis showed no significant difference of results after excluding individual studies, suggesting that the results were robust.
CONCLUSION
Aspirin may reduce the risk of HCC in both healthy population and patients with chronic liver disease. However, attention should be paid to adverse events such as gastrointestinal bleeding in patients with chronic liver disease.

INTRODUCTION
Cancer is a major global health concern, and immune checkpoint inhibitors (ICIs) offer a promising treatment option for cancer patients. However, the efficacy of ICIs can be influenced by various factors, including the use of concomitant medications.
METHODS
We searched databases (PubMed, Embase, Cochrane Library, Web of Science) for systematic reviews and meta-analyses for systematic reviews and meta-analyses on the impact of concomitant medications on ICIs efficacy, published from inception to January 1, 2023. We evaluated the methodological quality of the included meta-analyses, and re-synthesized data using a random-effects model and evidence stratification.
RESULTS
We included 23 publications, comprising 11 concomitant medications and 112 associations. Class II-IV evidence suggested that antibiotics have a negative impact on ICIs efficacy. However, ICIs efficacy against melanoma, hepatocellular carcinoma, and esophageal squamous cell carcinoma was not affected, this effect was related to the exposure window (class IV). Class III evidence suggested that proton pump inhibitors have a negative impact on ICIs efficacy; nevertheless, the efficacy against melanoma and renal cell carcinoma was not affected, and the effect was related to exposure before the initiation of ICIs therapy (class II). Although class II/III evidence suggested that steroids have a negative impact, this effect was not observed when used for non-cancer indications and immune-related adverse events (class IV). Class IV evidence suggested that opioids reduce ICIs efficacy, whereas statins and probiotics may improve ICIs efficacy. ICIs efficacy was not affected by histamine 2 receptor antagonists, aspirin, metformin, β-blockers, and nonsteroidal anti-inflammatory agents.
CONCLUSION
Current evidence suggests that the use of antibiotics, PPIs, steroids, and opioids has a negative impact on the efficacy of ICIs. However, this effect may vary depending on the type of tumor, the timing of exposure, and the intended application. Weak evidence suggests that statins and probiotics may enhance the efficacy of ICIs. Aspirin, metformin, β-blockers, and NSAIDs do not appear to affect the efficacy of ICIs. However, caution is advised in interpreting these results due to methodological limitations.

Meta-Analysis Review
PURPOSE
Dementia and Alzheimer's disease (AD) pose significant challenges to public health globally with no effective treatment strategies available. Therefore, the research focuses on developing effective prophylaxis to prevent the onset of these diseases. Recent studies have suggested that low-dose aspirin may help reduce the risk of dementia. Nonetheless, evidence regarding the correlation between aspirin consumption and the onset of dementia and AD is limited. This review aims to provide an up-to-date summary of the existing evidence and evaluate the association between aspirin and the onset of dementia and Alzheimer's disease.
METHODS
A systematic search of PubMed, Embase, Web of Science, PsycINFO, and CINAHL databases was conducted to find eligible studies published until April 2023. A random-effects meta-analysis of the eligible studies was then performed to assess the link between aspirin use and the onset of dementia and Alzheimer's disease. Additionally, we conducted subgroup analyses to evaluate the overall effect of low-dose (75-100 mg) aspirin consumption on the onset of dementia and AD.
RESULTS
A total of 875 studies were identified, with only 22 meeting the inclusion criteria. There was no statistically significant impact of aspirin consumption on the onset of dementia (HR 1.13, 11 studies) or Alzheimer's disease (HR 0.91, 3 studies). Additionally, subgroup analysis showed that taking low doses of aspirin (75-100 mg) did not significantly affect the onset of either dementia (HR 0.96, 13 studies) or Alzheimer's disease (HR 0.85, 2 studies).
CONCLUSIONS
Aspirin use does not decrease the risk of dementia or AD, even when taken in low doses. However, the quality of the studies analyzed was inadequate, with only three randomized controlled trials included in the review. Future high-quality studies are needed to assess the effect of aspirin consumption on these diseases. These findings may assist clinicians in selecting appropriate prophylactic strategies for patients at risk of developing dementia and AD.

Meta-Analysis Review
Breast Cancer (BC) is the most common cancer amongst women. The chemo-preventative effects of aspirin on breast cancer have been demonstrated in several longitudinal studies however previous meta-analysis have shown inconsistent results. This study aimed to assess the relationship between aspirin use and BC risk, and to determine if there is a dose-response relationship between aspirin and BC risk. Studies incorporating BC risk with aspirin use published within the last twenty years were included. The study report is based on the guidelines of Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) and Meta-Analysis of Observational Studies in Epidemiology. Twenty-eight cohort studies that reported BC incidence during a follow up of 4.4-32 years were included. Compared to non-users, aspirin users had a reduced risk of BC (HR = 0.91, c.i 0.81-0.97, p = 0.002). There was no obvious association between BC risk reduction and aspirin dose (HR = 0.94, c.i 0.85-1.04) or duration (HR = 0.86, c.i 0.71-1.03). Frequency, however, was associated with a reduced risk of BC (HR = 0.90, c.i 0.82-0.98). A risk reduction was observed in oestrogen receptor (ER) positive tumours (HR = 0.90, c.i 0.86-0.96, p = 0.0004) while no relationship was observed with ER negative tumours (HR = 0.94, c.i 0.85-1.05). This meta-analysis found an association between aspirin intake and BC risk reduction. A more favourable outcome was noted with ingestion of greater than 6 tablets of aspirin per week. Aspirin had a significant risk reduction in patients with ER positive tumours compared to ER negative BC.

Meta-Analysis Review
BACKGROUND
Carotid artery stenosis is narrowing of the carotid arteries. Asymptomatic carotid stenosis is when this narrowing occurs in people without a history or symptoms of this disease. It is caused by atherosclerosis; that is, the build-up of fats, cholesterol, and other substances in and on the artery walls. Atherosclerosis is more likely to occur in people with several risk factors, such as diabetes, hypertension, hyperlipidaemia, and smoking. As this damage can develop without symptoms, the first symptom can be a fatal or disabling stroke, known as ischaemic stroke. Carotid stenosis leading to ischaemic stroke is most common in men older than 70 years. Ischaemic stroke is a worldwide public health problem.
OBJECTIVES
To assess the effects of pharmacological interventions for the treatment of asymptomatic carotid stenosis in preventing neurological impairment, ipsilateral major or disabling stroke, death, major bleeding, and other outcomes.
SEARCH METHODS
We searched the Cochrane Stroke Group trials register, CENTRAL, MEDLINE, Embase, two other databases, and three trials registers from their inception to 9 August 2022. We also checked the reference lists of any relevant systematic reviews identified and contacted specialists in the field for additional references to trials.
SELECTION CRITERIA
We included all randomised controlled trials (RCTs), irrespective of publication status and language, comparing a pharmacological intervention to placebo, no treatment, or another pharmacological intervention for asymptomatic carotid stenosis.
DATA COLLECTION AND ANALYSIS
We used standard Cochrane methodological procedures. Two review authors independently extracted the data and assessed the risk of bias of the trials. A third author resolved disagreements when necessary. We assessed the evidence certainty for key outcomes using GRADE.
MAIN RESULTS
We included 34 RCTs with 11,571 participants. Data for meta-analysis were available from only 22 studies with 6887 participants. The mean follow-up period was 2.5 years. None of the 34 included studies assessed neurological impairment and quality of life. Antiplatelet agent (acetylsalicylic acid) versus placebo Acetylsalicylic acid (1 study, 372 participants) may result in little to no difference in ipsilateral major or disabling stroke (risk ratio (RR) 1.08, 95% confidence interval (CI) 0.47 to 2.47), stroke-related mortality (RR 1.40, 95% CI 0.54 to 3.59), progression of carotid stenosis (RR 1.16, 95% CI 0.79 to 1.71), and adverse events (RR 0.81, 95% CI 0.41 to 1.59), compared to placebo (all low-certainty evidence). The effect of acetylsalicylic acid on major bleeding is very uncertain (RR 0.98, 95% CI 0.06 to 15.53; very low-certainty evidence). The study did not measure neurological impairment or quality of life. Antihypertensive agents (metoprolol and chlorthalidone) versus placebo The antihypertensive agent, metoprolol, may result in no difference in ipsilateral major or disabling stroke (RR 0.14, 95% CI 0.02 to1.16; 1 study, 793 participants) and stroke-related mortality (RR 0.57, 95% CI 0.17 to 1.94; 1 study, 793 participants) compared to placebo (both low-certainty evidence). However, chlorthalidone may slow the progression of carotid stenosis (RR 0.45, 95% CI 0.23 to 0.91; 1 study, 129 participants; low-certainty evidence) compared to placebo. Neither study measured neurological impairment, major bleeding, adverse events, or quality of life. Anticoagulant agent (warfarin) versus placebo The evidence is very uncertain about the effects of warfarin (1 study, 919 participants) on major bleeding (RR 1.19, 95% CI 0.97 to 1.46; very low-certainty evidence), but it may reduce adverse events (RR 0.89, 95% CI 0.81 to 0.99; low-certainty evidence) compared to placebo. The study did not measure neurological impairment, ipsilateral major or disabling stroke, stroke-related mortality, progression of carotid stenosis, or quality of life. Lipid-lowering agents (atorvastatin, fluvastatin, lovastatin, pravastatin, probucol, and rosuvastatin) versus placebo or no treatment Lipid-lowering agents may result in little to no difference in ipsilateral major or disabling stroke (atorvastatin, lovastatin, pravastatin, and rosuvastatin; RR 0.36, 95% CI 0.09 to 1.53; 5 studies, 2235 participants) stroke-related mortality (lovastatin and pravastatin; RR 0.25, 95% CI 0.03 to 2.29; 2 studies, 1366 participants), and adverse events (fluvastatin, lovastatin, pravastatin, probucol, and rosuvastatin; RR 0.76, 95% CI 0.53 to1.10; 7 studies, 3726 participants) compared to placebo or no treatment (all low-certainty evidence). The studies did not measure neurological impairment, major bleeding, progression of carotid stenosis, or quality of life.
AUTHORS' CONCLUSIONS
Although there is no high-certainty evidence to support pharmacological intervention, this does not mean that pharmacological treatments are ineffective in preventing ischaemic cerebral events, morbidity, and mortality. High-quality RCTs are needed to better inform the best medical treatment that may reduce the burden of carotid stenosis. In the interim, clinicians will have to use other sources of information.

Meta-Analysis
BACKGROUND
Several clinical investigations have compared different pharmacologic agents for the prophylaxis of venous thromboembolism (VTE). However, no consensus has been reached. The present investigation compared enoxaparin, fondaparinux, aspirin and non-vitamin K antagonist oral anticoagulants (NOACs) commonly used as prophylaxis following total hip arthroplasty (THA). A Bayesian network meta-analysis was performed, setting as outcomes of interest the rate of deep venous thrombosis (DVT), pulmonary embolism (PE) and major and minor haemorrhages.
METHODS
This study was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) extension statement for reporting systematic reviews incorporating network meta-analyses of healthcare interventions. All randomised controlled trials (RCTs) comparing two or more drugs used for the prophylaxis of VTE following THA were accessed. PubMed, Web of Science and Google Scholar databases were accessed in March 2023 with no time constraint.
RESULTS
Data from 31,705 patients were extracted. Of these, 62% (19,824) were women, with age, sex ratio, and body mass index (BMI) being comparable at baseline. Apixaban 5 mg, fondaparinux, and rivaroxaban 60 mg were the most effective in reducing the rate of DVT. Dabigatran 220 mg, apixaban 5 mg, and aspirin 100 mg were the most effective in reducing the rate of PE. Apixaban 5 mg, ximelagatran 2 mg and aspirin 100 mg were associated with the lowest rate of major haemorrhages, while rivaroxaban 2.5 mg, apixaban 5 mg and enoxaparin 40 mg were associated with the lowest rate of minor haemorrhages.
CONCLUSION
Administration of apixaban 5 mg demonstrated the best balance between VTE prevention and haemorrhage control following THA. Level of evidence Level I, network meta-analysis of RCTs.

Meta-Analysis
BACKGROUND
A systematic review and network meta-analysis (NMA) were conducted to explore the efficacy and safety of different antiplatelet or anticoagulation drugs in chronic coronary syndromes patients.
METHODS
Electronic databases (Pubmed, Embase and Cochrane databases) were systematically searched to identify randomized controlled trials evaluating different antiplatelet or anticoagulation drugs (aspirin, aspirin + clopidogrel, aspirin + clopidogrel + cilostazol, clopidogrel/prasugrel + aspirin, aspirin + rivaoxaban 2.5 mg, aspirin + ticagrelor 60 mg, aspirin + ticagrelor 90 mg, clopidogrel or rivroxaban 5 mg) versus placebo for treatment chronic coronary syndromes patients. Outcomes included major adverse cardiovascular events, all cause death, major bleeding and myocardial infarction. A random-effect Bayesian NMA was conducted for outcomes of interest, and results were presented as odds ratios (ORs) and 95% credible intervals. The NMA was performed using R Software with a GeMTC package. A Bayesian NMA was performed and relative ranking of agents was assessed using surface under the cumulative ranking probabilities.
RESULTS
Ten randomized controlled trials met criteria for inclusion and finally included in this NMA. In head-to-head comparison, no significant difference was observed between all antithrombotic treatment strategies with respect to primary endpoint of major adverse cardiovascular events. In head-to-head comparison, no significant difference was observed between all antithrombotic treatment strategies with respect to all cause death. Clopidogrel/prasugrel + aspirin (OR = 3.8, 95% credible intervals [CrI]: 1.3-12.0, P < .05) and aspirin + rivaroxaban 2.5 mg (OR = 3.1, 95%CrI: 1.1-9.5, P < .05) was associated with an increase of the major bleeding. Compared with aspirin alone, aspirin + clopidogrel (OR = 0.42, 95%CrI: 0.22-0.76, P < .05) and aspirin + ticagrelor 90 mg (OR = 0.42, 95%CrI: 0.17-0.95, P < .05) was associated with a decrease of the myocardial infarction.
CONCLUSIONS
Myocardial infarction was significantly lower when adding clopidogrel or ticagrelor 90 mg to aspirin than those in the aspirin alone group. However, clopidogrel/prasugrel and rivaroxaban 2.5 mg was associated with an increase of the major bleeding than aspirin alone.

Meta-Analysis
PURPOSE
Patients undergoing total knee arthroplasty (TKA) are at high risk for thromboembolic events compared to non-surgical patients. Both anticoagulants and antiplatelet agents are used as antithrombotic prophylaxis in TKA. The aim of this review is to understand the role of aspirin in the prevention of thromboembolic events and to compare its efficacy and safety with the main anticoagulants used in antithromboembolic prophylaxis in TKA.
METHODS
A systematic review and meta-analysis was performed according to the PRISMA guidelines. An electronic systematic search was conducted using PubMed, Scopus, and the Cochrane Central Registry to evaluate studies that compared aspirin with other anticoagulants, in terms of deep venous thrombosis and pulmonary embolism after TKA. The meta-analysis compared the rate of complications between aspirin and other anticoagulants.
RESULTS
Thirteen studies were included in the systematic review for a total of 163,983 patients, and 10 studies were included in the meta-analysis. The meta-analysis demonstrated no statistically significant differences between aspirin and other anticoagulants in terms of the rate of deep venous thrombosis (OR 0.93, 95% CI 0.81-1.08, p = 0.35) and pulmonary embolism (OR 0.89, 95% CI 0.56-1.41, p = 0.61).
CONCLUSION
Aspirin is safe, effective, and not inferior to other main anticoagulants in preventing thromboembolic events following TKA.

Meta-Analysis
OBJECTIVE
Non-valvular atrial fibrillation (NVAF) is a common manifestation of cardiac arrhythmia, whose significance is heightened in the context of an aging global population and changing lifestyles, leading to an increased incidence. Stroke prevention in NVAF is a complex challenge that requires a comprehensive exploration of interventions. The emergence of Direct Oral Anticoagulants (DOACs) is a potential treatment, necessitating a thorough evaluation of their safety and efficacy. As the quest for the best strategy for thrombotic risk in these patients continues, the interaction between DOAC and aspirin has become the focus of research.
MATERIALS AND METHODS
With a rigorous methodological approach, we conducted a thorough search of scientific databases up to August 2023. The methodology involved meticulous screening, careful data extraction, and rigorous assessment of trial quality, all conducted by two independent investigators. The results were synthesized through standardized mean differences, accompanied by 95% confidence intervals.
RESULTS
DOACs demonstrated significant enhancements in stroke prevention for NVAF, which was indicated by favorable outcomes in bleeding (RR = 4.04, 95% CI: 3.96, 4.12), coronary artery disease (RR = 2.45, 95% CI: 2.42, 2.48), mortality (RR = 0.49, 95% CI: 0.43, 0.56), myocardial infarction (RR = 1.85, 95% CI: 1.81, 1.88), and stroke (RR = 1.50, 95% CI: 1.47, 1.54). Notably, DOACs demonstrated optimal efficacy for NVAF patients with stroke.
CONCLUSIONS
DOACs may be potentially effective for preventing stroke after NVAF.
