Single vs. Dual Antiplatelet Therapy in Elderly or HBR Patients Undergoing Percutaneous Intervention With DCB (PICCOLETO IV-EPIC 38)

This international, multicenter, open-label, randomized clinical trial evaluates the safety and efficacy of single antiplatelet therapy (SAPT) compared to dual antiplatelet therapy (DAPT) in elderly or high bleeding risk patients undergoing percutaneous coronary intervention (PCI) with the latest generation drug-coated balloon (DCB). The study includes patients with stable or unstable coronary syndromes and aims to assess rates of ischemic and bleeding adverse events.

Low Dose Aspirin Alerts in High-Risk Pregnancies

The goal of this study is to assess the effect of an electronic health record (EHR) clinical decision support tool, also known as a best practice alert (BPA), on healthcare provider recommendations for low dose aspirin use in a high-risk pregnant patient population. The investigators hypothesize that the implementation of the EHR BPA tool will increase the healthcare provider's recommendation for low dose aspirin compared to current standard care.

Assessing Pharmacokinetics and Pharmacodynamics of Daily Enteric-coated Aspirin in Patients With StablE Diabetes II

This phase 2 study will include patients suffering from type 2 diabetes mellitus and will first study their response to enteric coated aspirin at a dose of 80 mg per day for a 7-day period. Participants with an incomplete platelet inhibition after exposure to EC aspirin at doses of 80 mg once daily will be randomized to a random order of 3 different ASA regimens: EC ASA 162 mg once daily, EC ASA 81 mg twice daily and chewable ASA 40 mg twice daily. The aims are to determine the feasibility of a larger scale trial, and to determine the regimen associated with the lowest proportion of non-responders after randomization. Platelet function will be assessed at baseline and at day 7 of each arms of the study.

Chronic Hypertension and Acetyl Salicylic Acid in Pregnancy

A randomized clinical trial to assess the efficiency of acetylsalicylic acid (aspirin) 150 mg/day started before 20 weeks of gestation in the prevention on maternal and fœtal complications in pregnant women with chronic hypertension.

Non-antithrombotic Versus. Single Antiplatelet Therapy Following Left Atrial Appendage Closure

The goal of this clinical trial is to verify that Non-Antithrombotic Therapy (NAPT) followed by Oral Anticoagulants (OAC) monotherapy for 45 days after Left Atrial Appendage Closure (LAAC) is non-inferior to Single Antiplatelet Therapy (SAPT) with aspirin during the period from randomization to the end of observational period (4 years at the maximum) in non-valvular atrial fibrillation subjects with high bleeding risk. The primary endpoint is a composite endpoint consisting of all-cause mortality, myocardial infarction, stroke, systemic embolism, major bleeding, or clinically relevant non-fatal bleeding from randomization to the end of study observation (up to a maximum follow-up of 4 years). * Participants will be enrolled in this study until the day following the implementation of LAAC and will be randomized to the SAPT arm and NAPT arm in a 1:1 ratio. * Participants will be observed for 4 years from the time the first subject is enrolled in this study. * Participants will visit the hospital at 45 days, 1 year, and 2 years after enrollment, and will also be followed up by telephone, basically at the end of the observation period (up to a maximum follow-up of 4 years). \<Study treatment duration\> In both arms, OAC monotherapy will be initiated in the first 24 hours of enrollment and continued for 45 days (allowed window period: plus 2 weeks).. * SAPT arm will continue to receive 45 days of OAC monotherapy followed by low-dose aspirin (75～100 mg/day) as an antithrombotic agent required through the end of the study observation period. * NAPT arm do not receive antithrombotic medication after 45 days of OAC monotherapy through the end of the study observation period.

Immunomodulation During Pregnancy

The goal of this observational study is to learn about the effects of low dose aspirin in immunity Pregnant women taking aspirin for other reasons (preeclampsia prevention) will be studied. The main question it aims to answer is: evaluate the effect of LDA on the modulation of innate immunity cells (NK cells, monocytes, γδ T cells) and/or acquired immunity (B and T lymphocytes, Treg cells, Th cells). Participants already taking intervention A as part of their regular medical care for RA will answer online survey questions about their joint pain for 5 years.

The PARTUM Trial: Postpartum Aspirin to Reduce Thromboembolism Undue Morbidity

The goal of the PARTUM trial is to determine if taking low-dose aspirin daily for 6 weeks after delivery is similar (non-inferior) to usual care low-molecular-weight heparin injections to prevent venous thromboembolism (VTE: blood clots in the legs or lungs) for postpartum individuals with VTE risk factors.

Aspirin Use for Gastric Cancer Prevention in the Early Gastric Cancer Patients

This study aimed to investigate the effect of low-dose (100 mg) asprin on the prevention of gastric cancer in the early gastric cancer patients with negative H. pylori status who underwent endoscopic submucosal dissection.

Non-antithrombotic Therapy After Transcatheter Aortic Valve Implantation Trial

Aspirin group: Aspirin 100mg will be started within 24 hours after randomization, and continued aspirin 100mg/day the end of the study period. Non-antithrombotic group: No antithrombotic agents will be administered after randomization until the end of the study period.

The Effect of Aspirin on Recurrent Acute Pancreatitis

Recurrent acute pancreatitis (RAP) was defined as two or more occurrences of acute pancreatitis, which was associated with higher percentages of morbidities and mortalities, lower patients' life quality and increased health-care costs. Current interventions, including cholecystectomy and abstain from drinking were reported to be effective methods for preventing the recurrences of biliary and alcoholic etiologies, respectively. However, there were no effective preventions for other etiologies, such as idiopathic etiologies. Non-steroid anti-inflammatory drugs (NSAIDs), including indomethacin, diclofenac and aspirin could inhibiting the inflammatory cascade of pancreatitis. In this study, we aimed at exploring the effects of 100mg aspirin on reducing the occurrences of recurrent acute pancreatitis.
