AI Article Synopsis
- This study compares kidney transplant outcomes from donors aged 60+ to those aged 40-59, focusing on medium-term recipient and graft survival.
- Results show that kidney recipients from older donors had higher serum creatinine levels, indicating poorer kidney function after 3 and 5 years, along with reduced recipient and graft survival times.
- Cardiovascular disease as a cause of donor death is identified as a significant risk factor for kidney graft loss in the transplants from older donors.
Article Abstract
Objective: To analyze results of transplantation of kidneys procured from donors after brain death aged 60 years and older (hereafter denoted by "≥60") compared to kidneys procured from donors after brain death aged 40-59 years (hereafter denoted by "40-59") in medium-term follow-up period, and to assess factors that affect recipient and kidney graft survival.
Material And Methods: 92 transplant recipients of kidneys procured from donors after brain death ≥60 were enrolled into the study. The control group were 363 recipients of kidneys procured from donors after brain death 40-59.
Results: Mean values of serum creatinine were higher in recipients of kidneys procured from donors after brain death ≥60 compared to control after 3 years: 168.2 ± 57.5 (n = 59) vs 147.9 ± 65.7 (n = 294), P < .05; and after 5 years: 196.2 ± 95.3 (n = 38) vs 157.3 ± 80.0 μmol/L (n = 211), P < .01. Restricted mean recipient survival time was 56.4 (95% confidence interval: 55.0-57.8) and 52.0 (48.0-56.1) months, P < .05; and kidney graft survival time was 51.6 (49.6-53.5) and 43.9 (39.0-48.9) months, P < .01 in recipients who received kidneys from donors after brain death 40-59 and from donors after brain death ≥60 respectively. In Cox regression, donor death due to cardiovascular disease proved to be the factor increasing risk of kidney graft loss (hazard ratio 1.553, P < .001).
Conclusions: The survival and function of kidneys procured from donors after brain death ≥60 at medium-term follow-up remain worse compared to kidneys procured from donors after brain death 40-59, and the donor dependent risk factor of kidney graft loss is cardiovascular disease, which caused donor death.

Patients with kidney failure require dialysis or kidney transplantation. Kidney transplantation offers great benefits, including reduced mortality; however, many patients who wish to undergo kidney transplantation are unable to do so due to a shortage of donor organs. This shortage is a global issue, and xenotransplantation has emerged as a potential solution.

Among the intrinsic and environmental processes promoting cell-to-cell interaction processes, eventually driving GBM invasion, we focused on the pro-invasive role played by Extracellular Vesicles (EVs), a heterogeneous group of cell-released membranous structures containing various bioactive cargoes, which can be transferred from donor to recipient cells.
Methods: EVs isolated from patient-derived GBM cell lines and surgical aspirates were assessed for their pro-migratory competence by spheroid migration assays, calcium imaging, and PYK-2/FAK phosphorylation.

Background: Single-cell RNA sequencing (scRNA-seq) has improved our ability to characterize rare cell populations. In practice, cells from different tissues or donors are simultaneously loaded onto the instrument (multiplexed) at the recommended (standard loading) or higher (superloading) numbers to save time and money. Although cost-effective, superloading can stymie computational analyses owing to high multiplet rates and sample complexity.

The diagnostic landscape of brain tumors integrates comprehensive molecular markers alongside traditional histopathological evaluation. DNA methylation and next-generation sequencing (NGS) have become a cornerstone in central nervous system (CNS) tumor classification. A limiting requirement for NGS and methylation profiling is sufficient DNA quality and quantity, which restrict its feasibility.

Background: Scalp reconstruction is a challenging field for plastic surgeons. In case of large or complex defects, microsurgical-free flaps are usually required. Reconstructive failure can result in high morbidity and in some cases be life-threatening.
