Association of Recipient APOL1 Kidney Risk Alleles With Kidney Transplant Outcomes.

Background: Kidney transplant survival in African American recipients is lower compared with non-African American transplant recipients. APOL1 risk alleles (RA) have been postulated as likely contributors. We examined the graft outcomes in kidney transplant recipients (KTRs) stratified by APOL1 RA status in a multicenter observational prospective study.

Patient's knowledge of daily activities, need for information and quality of life after cardiac electronic device implantation.

Introduction: Cardiac implantable electronic devices (CIED) such as pacemakers or cardioverter defibrillators prevent dangerous heart arrhythmias and conduction abnormalities. Post-intervention education is crucial in the patient recovery process and aims to avoid both dangerous behavior and unnecessary restraints in daily living.

Objective: The evaluation of knowledge of daily activities' safety among patients with CIEDs and an analysis of the relationship between the state of knowledge and perceived post-intervention quality of life.

Changes in Body Composition, Muscle Strength, and Fat Distribution Following Kidney Transplantation.

Rationale & Objective: Low muscle mass relative to fat mass (relative sarcopenia) has been associated with mortality and disability but has not been examined after kidney transplantation. We studied how measures of body composition change after receipt of a kidney allograft.

Study Design: Prospective longitudinal cohort study.

MATRA-A: A study on massive transfusion.

Background: We use massive transfusion in various clinical conditions and it is associated with high mortality. Although some massive transfusion protocols improve patient outcomes, the clinical circumstances requiring it are not well defined.

Methods: MATRA-A is a multicenter retrospective study.
