[Management of immunosuppressive therapy in kidney transplant recipients with COVID19. A multicentre national study derived form the S.E.N. COVID registry.].

Introduction: SARS CoV2 infection has had a major impact on renal transplant patients with a high mortality in the first months of the pandemic. Intentional reduction of immunosuppressive therapy has been postulated as one of the cornerstone in the management of the infection in the absence of targeted antiviral treatment. This has been modified according to the patient`s clinical situation and its effect on renal function or anti-HLA antibodies in the medium term has not been evaluated.

Early glomerular filtration rate changes in living kidney donors and recipients: an example of renal plasticity.

Background: In living kidney transplantation there are two different individuals, a healthy donor and a renal transplant recipient. This is an excellent human model to study factors that influence kidney function in the context of reduced renal mass and the adaptation of two comparable kidneys to different metabolic demands.

Methods: We analyzed the changes in measured glomerular filtration rate (GFR, iohexol) from pretransplantation to 12 months after transplantation in 30 donor-recipient pairs.

Analysis of the third-order structuring of Shalom Schwartz's theory of basic human values.

Shalom Schwartz's Theory of Basic Human Values is one of the most commonly used and tested transcultural theories in the field of behavioural research. This theory has been refined since the 1980s to reach its most recent version, from 2012. The underlying reason for this theory's continuous evolution is that it assumes that values form a circular motivational continuum, meaning that the items do not have exact limits between the values and thus have a shared load on more than one, giving rise to multicollinearity.

Pre-transplant weight but not weight gain is associated with new-onset diabetes after transplantation: a multi-centre cohort Spanish study.

Background. New-onset diabetes after transplantation (NODAT) is associated with poorer outcomes in kidney transplantation (KT). Thus, identification of modifiable risk factors may be crucial for ameliorating the impact of this entity on transplant outcomes.

Increased cardiovascular risk profile and mortality in kidney allograft recipients with post-transplant diabetes mellitus in Spain.

Background: Post-transplant diabetes mellitus (PTDM) is associated with poorer outcomes in kidney transplantation (KT) but little information exists about the evolution of traditional cardiovascular risk (CVR) factors under this disorder.

Methods: We retrospectively analysed CVR factors at 3, 12 and 24 months of follow-up and mortality at three yr in 3365 KT performed in Spain during the years 1990, 1994 and 1998 with a functioning graft after the first year. Three groups were considered: (i) (PTDM, n, 251), (ii) diabetes mellitus as primary disease (DM, n = 156) and (iii) the remaining patients (controls, n = 2958).
