  • Patent number: 12623013
    Abstract: Compounds, systems, kits, methods, and/or apparatuses may be operative to reduce amyloid beta (A?) peptide in a patient, including a central nervous system (CNS) of the patient and/or a periphery (non-CNS portion) of the patient. In some embodiments, a displacer fluid comprising a A? displacer may be introduced to the patient to bind to a blood protein, such as albumin, that binds A? (for instance, A? peptide or non-plaque A?) in the patient periphery. Binding of the displacer to the blood protein may facilitate more free A? peptide (for instance, A? monomers) in the periphery for clearance via natural processes, such as through the liver or kidneys, and/or artificial processes, such as dialysis. Increased removal of the free A? peptide in the periphery may ultimately lead to less A? peptide in the CNS, which may decrease A? plaque formation in Alzheimer's Disease (AD) patients. Other embodiments are described.

  • Publication number: 20250079022
    Abstract: Techniques for patient population flow modeling are disclosed, where such modeling can provide insights for future trends among a patient population, e.g., to facilitate allocation of resources for the patient population or to inform treatment recommendations for patients. A flow model can be used on dialysis patient populations where the patients are grouped into a compartment according to a certain criterion (or given criteria), where each compartment corresponds to the number of patients in each group, and where the number of compartments can vary depending on the given criteria. A model can then be used to describe the transition rates between the different compartments, as well as influx and efflux within each compartment. Such a model can be used, by way of example, to investigate the impact of sodium-glucose co-transporter 2 (SGLT2) inhibitors on the population dynamics of end-stage renal disease patients.
