AI Article Synopsis

  • The study investigates kidney transplant outcomes comparing donors after controlled cardiac death (cDCD) and expanded criteria brain death (DBD-EC) donors to address donor shortages.
  • It analyzes data from 129 cDCD and 166 DBD-EC kidney transplant recipients over a median follow-up of 30.2 months, revealing similar rates of early complications and one-year patient survival (85% for DBD-EC vs. 90% for cDCD).
  • The findings suggest that cDCD can be a viable donor option, especially when considering older and more comorbid DBD donors, indicating that recipient characteristics should inform donor selection.

Article Abstract

Background: The persistent shortage of optimal kidney donors and the progressive increase in patients on the waiting list have led to an expansion of the acceptance criteria, such as donors after controlled cardiac death (cDCD) and donors after brain death with expanded criteria (DBD-EC). Some concerns and doubts about survival outcomes achieved with these allografts are still present. Our aim was to compare transplant outcomes from cDCD vs DBD-EC.

Methods: A retrospective single-center observational study including all kidney transplant (KT) donors from all cDCD and DBD-EC (>60 years) from January 2015 to January 2022 was performed. We analyzed clinical characteristics, early clinical outcomes, and patient and graft survival rates.

Results: 129 cDCD and 166 DBD-EC KT recipients were included. The median follow-up was 30,2 months. DBD-EC were older and had more comorbidities than cDCD. KTs from cDCD and DBD-EC showed similar rates of delayed graft function and primary nonfunction. Patient survival at 1 year was similar (85% DBD-EC vs 90% cDCD, P = .32). Death-censored graft survival at 1 year was similar among young cDCD (18-59 years) and elderly DBD (60-69 years; 97% vs 92.3%, P = .2). Recipient age and expanded criteria in KT from cDCD were related to worse early graft outcomes. The outcomes achieved with KT from cDCD were similar to those observed in older and more comorbid DBD donors. This assumption is worth consideration when choosing the most suitable donor for each recipient.

Background: Data collection through patient-reported outcome measures (PROMs) is essential for the purpose of rehabilitation research and registries. Existing problems with incomplete PROM data may relate to the patient burden and data set length. This study aimed to analyse response patterns and degree of data completeness in systematic outcome assessments conducted within a clinical study in a multidisciplinary rehabilitation setting, comparing completeness of a brief and a longer set of PROMs.

Background: Genu varum, or bow-legged deformity, involves an outward curvature of the lower limbs, often creating a visible gap between the knees when the ankles are together. Traditionally treated with invasive surgical methods like high tibial osteotomy, genu varum correction now includes less invasive options for patients with mild to moderate deformities. This commentary explores a novel approach using hyaluronic acid (HA) filler to volumise the medial gastrocnemius muscle, thereby improving calf contour and stability without surgery.

Contemporary fertility care has matured from a restricted, special interest in women's health care where success sometimes made magazine covers to a well-honed start-to-finish process with ever-improving success rates and an ever-expanding panoply of treatment options. Innovations in both lab and clinic have been exponential and game changing. The specialty now finds itself in the enviable position of an extensive menu of highly successful treatment options but a complicated set of circumstances of access to these options.
