Antiphospholipid syndrome (APS) is an acquired thrombophilia associated with autoimmunity and is a syndrome that should always be considered when examining patients with thrombosis and pregnancy complications. As per the Sydney criteria, a diagnosis can be established with at least one clinical finding, such as arteriovenous thrombosis and the presence of at least one of the antiphospholipid antibodies (aPL), such as anticardiolipin antibodies (aCL). Moreover, phosphatidylserine-dependent anti-prothrombin antibody and anti-b2GPI-domain 1 antibody are correlated with APS manifestations and enable APS diagnosis. In addition to the inhibition of physiological coagulation inhibitors, such as protein C, the activation of vascular endothelial cells and complement activation by aPL is presumed to be the thrombus mechanism of APS. The mainstay of treatment is anticoagulant therapy with warfarin. For treating APS that has developed by arterial thrombosis, antiplatelet agent alone or in combination with warfarin is considered. In the triple positive aPL (aCL, anti-b2GPI antibodies, and lupus anticoagulant are detected at the same time) cases, sufficient anticoagulant therapy is required. Direct oral anticoagulants are not recommended in cases of triple positive aPL or arterial thrombosis. For patients with catastrophic APS, heparin therapy, plasmapheresis, and steroid pulse therapy are recommended.

Alzheimer's disease is the neurodegenerative disorder responsible for approximately 60% to 70% of all cases of dementia and is expected to affect 152 million by 2050. Recently, anti-amyloid therapies have been developed and approved by the Food and Drug Administration as disease-modifying treatments given as infusions every 2 to 5 weeks for Alzheimer's disease. Although this is an important milestone in mitigating Alzheimer's disease progression, it is critical for emergency medicine clinicians to understand what anti-amyloid therapies are and how they work to recognize, treat, and mitigate their adverse effects.

The management of anticoagulation and antiplatelet therapy in stage V chronic kidney disease (CKD) patients undergoing renal transplantation remains controversial. Some centers advocate for the use of reversal agents or procoagulants preoperatively, while others suggest that transplantation can proceed safely without halting these treatments. This study aims to evaluate the incidence of hemorrhagic and thrombotic complications in the first 72 hours post-transplant in patients receiving anticoagulant or antiplatelet therapy compared to a control group without such treatments.

This procedure is carried out via a full sternotomy using standard aortic and bicaval cannulations. For the aortic and pulmonary anastomoses, selective antegrade unilateral cerebral perfusion is used after cooling the body temperature to 26 °Celsius. A 12-mm Hancock conduit is interposed between the pulmonary artery and the proximal descending aorta using standard running suture techniques.

Pharmacogenomics stands as a pivotal driver toward personalized medicine, aiming to optimize drug efficacy while minimizing adverse effects by uncovering the impact of genetic variations on inter-individual outcome variability. Despite its promise, the intricate landscape of drug metabolism introduces complexity, where the correlation between drug response and genes can be shaped by numerous nongenetic factors, often exhibiting heterogeneity across diverse subpopulations. This challenge is particularly pronounced in datasets such as the International Warfarin Pharmacogenetic Consortium (IWPC), which encompasses diverse patient information from multiple nations.
