Framingham risk score is a useful indicator of posttransplant cardiovascular events and survival among Korean kidney transplant recipients: a nationwide, prospective cohort study.

Background: Cardiovascular disease is an important risk factor for mortality among kidney transplant recipients. In this study, we aimed to investigate the association between cardiovascular risk score at kidney transplantation and long-term outcomes of patients.

Methods: In this prospective, observational cohort study, we enrolled kidney transplant recipients who participated in the Korean Organ Transplantation Registry and underwent transplantation between April 2014 and December 2019.

Performance optimization of H(-) multicusp ion source for KIRAMS-30 cyclotron.

KIRAMS-30 cyclotron has been developed and implemented for radio isotope production. For the purpose of producing negative hydrogen ions and low energy beam injection to the central region of KIRAMS-30, 10 mA H(-) multicusp ion source with beam kinetic energies in the 20-30 keV range and the normalized 4 rms emittance less than 1 mm mrad was installed. The optimized ion source operating condition is presented and the correlation between the extracted beam current and ion source parameters is described for the performance enhancement of the ion source.
