Purpose: Uric acid is an independent factor for arteriosclerotic cardiovascular disease (ASCVD). Although aspirin is one of the most widely used agent in patients with ASCVD, there were only a few studies focusing on the effects of low-dose aspirin on uric acid metabolism with controversial results. The present study aimed to investigate an association between low-dose aspirin treatment for more than one month and serum uric acid (SUA) with its urinary excretion in elderly patients.
Patients And Methods: This paper presents an observational retrospective cross-sectional study to determine the association between continuous daily taking low-dose aspirin (50-100mg) for more than one month and SUA with fraction excretion of uric acid (FEUA) in elderly patients. A total of 506 inpatients equal or over 60 in Department of Geriatrics of Peking University First Hospital were enrolled from 2017 to 2020. About 41.9% of them were taking aspirin for more than one month, while others were not taking this medicine. The correlation between aspirin use and SUA or FEUA was analyzed, and group-comparison was performed in different dosage groups of aspirin.
Results: After correcting confounding factors, there is no remarkable correlation between taking low-dose aspirin and SUA or FEUA, but a decreasing trend (coefficients=-4.946) of SUA in hyperuricemia patients with low-dose aspirin was observed despite no obvious difference (P=0.534). Whether SUA or FEUA has no significant difference between 50mg/d and 100mg/d aspirin subjects.
Conclusion: SUA and urinary uric acid excretion are not associated with using of 50-100mg/d aspirin for more than one month in elderly patients with ASCVD or at risk.

Preterm preeclampsia screening and prevention: a comprehensive approach to implementation in a real-world setting.
BMC Pregnancy Childbirth
January 2025
Genetic Program, North York General Hospital, Toronto, ON, Canada.
Background: Preeclampsia significantly impacts maternal and perinatal health. Early screening using advanced models and primary prevention with low-dose acetylsalicylic acid for high-risk populations is crucial to reduce the disease's incidence. This study assesses the feasibility of implementing preterm preeclampsia screening and prevention by leveraging information from our current aneuploidy screening program in a real-world setting with geographic separation clinical site and laboratory analysis site.

Background: Nasopharyngeal cancer (NPC) is a common head and neck malignant tumor, which is difficult to treat at the advanced NPC due to its occult and high metastatic potential to the cervical lymph nodes and distant organs. Low-dose radiotherapy (LDRT) is increasingly being investigated for potential cancer treatment. When combined with immune checkpoint inhibitors, LDRT has been shown to significantly improve the immune microenvironment of tumors, thereby promote the immune attack on tumor cells.

Background: The overexpression of HMGB1 at the maternal-fetal interface (MFI) is recognized as a significant factor in Unexplained Recurrent Spontaneous Abortion (URSA). This study aimed to investigate autophagy in the decidual tissues of URSA patients and to explore the relationship between HMGB1 and macrophage autophagy at the MFI in URSA.
Methods: Human decidual tissues were collected from 40 patients diagnosed with URSA and from 60 women undergoing active termination of pregnancy.

Population Health Research Institute, University of British Columbia, Vancouver, Canada. (M.A.S., J.W.E., A.H.K., A. Shoamanesh, A.T., R.G.H., A.C., R.Z.).
Background: Stroke secondary to intracranial atherosclerotic disease (ICAD) is associated with high recurrence risk despite currently available secondary prevention strategies. In patients with systemic atherosclerosis, a significant reduction of stroke risk with no increase in intracranial or fatal hemorrhage was seen when rivaroxaban 2.5 mg twice daily was added to aspirin.

Diagnosis involves confirming the persistence of antiphospholipid antibodies in symptomatic patients, using validated classification criteria as a guide. The likelihood of obtaining false-positive or false-negative test results in certain settings, and the lack of standardisation between laboratory methods, are important considerations.
