BK virus-associated nephritis (BKVAN) is an important cause of graft loss in renal transplant recipients B K viremia occurs in up to 30% of renal transplant recipients. Since the discovery of BKV in 1971, effective prophylaxis and treatment have not been established, and it is not uncommon for a transplant kidney to be lost without cure of BKVAN. BK virus infection is reactivated when cellular immunity is suppressed, which is often during the first year after kidney transplantation when cellular immunity is most suppressed.

Orbital torque (OT) in magnetic heterostructures has been actively discussed in terms of its actual existence and usefulness in comparison to the spin-orbit torque (SOT) that shows promise for next-generation magnetoresistive random access memories. The objectives of this study are 2-fold: (i) making an apples-to-apples comparison in two representative stacks where OT and SOT are expected to dominate and (ii) examining the potential emergence of OT in archetypal SOT stacks. Cr/CoFeB/MgO and W/CoFeB/MgO are chosen as the OT- and SOT-dominant systems, respectively.

A 41-year-old woman diagnosed with seronegative myasthenia gravis struggled to maintain remission for a decade, facing crises every 3 months for several years. After repeated apheresis using a non-tunneled non-cuffed central venous dialysis catheter (NTNCC), complications such as catheter-related thrombus in the internal jugular veins and morbid obesity from steroids made the insertion of NTNCC increasingly difficult, leading to consideration of an alternative permanent vascular access (VA) approach. Thus, we created a subcutaneously superficialized brachial artery as the VA, which allowed the patient to undergo safe and uninterrupted apheresis therapy.

Background: Dialysis central venous catheters (DCs) are used for various blood purification therapies. Accidental removal of a DC is a potentially life-threatening event. However, the risk factors associated with accidental removal have rarely been discussed in the literature.
