The coagulation profile of oophorectomised women on long-term (15 yr) hormone replacement therapy with mestranol (30 micrograms/day) is compared to that of women on long-term placebo. Analysis of these data showed no significant difference in prothrombin time, partial thromboplastin time or in anti-thrombin III level in these groups.

Background: In addition to its important roles in blood coagulation and bone formation, vitamin K (VK) contributes to brain function. Low dietary VK intake, which is common among older adults, is associated with age-related cognitive impairment.
Objective: To elucidate the biological mechanisms underlying VK's effects on cognition, we investigated the effects of low VK (LVK) intake on cognition in C57BL/6 mice.

Objective: To investigate the predictive value of soluble FMS-like tyrosine kinase-1 (sFlt-1), coagulation function, and platelet (PLT) parameters for preeclampsia (PE).
Methods: A prospective study was conducted on women registered and delivered at XXXX Hospital from October 2020 to December 2021. All eligible pregnant women were recruited at the time of initial registration in the first trimester.

Cognitive impairment, marked by a decline in essential mental aspects such as attention, memory, and problem-solving, is significantly correlated with advancing age. This condition presents a major challenge for the elderly, adversely affecting quality of life, diminishing independence, and imposing substantial burdens on healthcare systems. Recent research indicates that vitamin K2 may be vital for preserving brain health and cognitive function.

Objectives: Chronic Kidney Disease (CKD) has been associated with a prothrombotic state. CKD affects hemostasis through altered platelet function and coagulation factors. Traditional tests provide limited insight into these changes.

BACKGROUND Lupus anticoagulants (LA) can interfere with routine coagulation tests such as the activated partial thromboplastin time (aPTT) and prothrombin time (PT). The international normalized ratio (INR) is derived from PT and is used to monitor warfarin therapy. A positive LA result is one of the laboratory criteria of the 2023 ACR/EULAR antiphospholipid syndrome (APS) classification criteria.
