Dialysis facilities referred more incident patients, transplant centers evaluated more, but fewer were placed on the waitlist following KAS implementation. This led to a decline in overall waitlisting nationwide.
A cost-effectiveness analysis found that adherence promotion programs like MAPS reduce costs and improve outcomes for adolescent kidney transplant recipients. Strategies with similar costs to MAPS can still be cost-effective if they decrease rejection episodes by a small amount.
Young adults are disproportionately excluded from kidney transplantation, with only 1.8% of Black and 4.4% of Hispanic patients receiving the treatment compared to 10.9% of White patients within this age group. The study highlights the need for targeted interventions to address these disparities.

The decline was attributed to changes in healthcare delivery and may reflect delays in treatment due to fear of infection or logistical barriers.
Research provides insights on immune responses of kidney transplant recipients following SARS-CoV-2 infection. The study found that production of IgG antibodies against the virus was delayed in these individuals, but their IgM and IgA responses were similar to those observed in non-transplant individuals.
The study reveals that SARS-CoV-2 damages the kidneys by interacting with ACE2, leading to an imbalance in blood pressure regulation and inflammation. This can result in impaired kidney function, reduced glomerular filtration rate, and increased risk of acute renal injury.

The study suggests that FMT may not be an effective treatment option for this condition, and future research is needed to explore its potential benefits.
Patients waiting for a kidney transplant who experienced various symptoms had a higher risk of dying while on the waitlist. However, those who underwent transplantation saw an improvement in symptoms, with overall 10% reduction and significant declines in fatigue and itchy skin.
A new study reveals that many patients with high-priority kidney transplants are not being placed on the transplant waiting list, despite having long expected post-transplant survival. African Americans, uninsured individuals, and those living in lower-income communities face significant barriers to expedited waitlist placement.
A new analysis found that post-heart transplant survival among older patients is on par with younger recipients. The study included 37,135 patients and showed a significant improvement in mortality rates after adjusting for other factors, suggesting that advanced age should not be a contraindication for heart transplantation.
A new study published in the Journal of the American Geriatrics Society found that heart transplant surgery has a similar mortality rate for adults aged 18-69 and 70+, with only minor differences in stroke risk and donor hearts. Advanced age alone should not prevent people from being considered as candidates for heart transplants.

The researchers also identified striking disparities in access to transplantation, highlighting the need for more effective strategies to ...
A study of over 23,000 heart transplant recipients found that young Black adults are more likely to die in the first year after a transplant. Researchers attribute this disparity to factors such as limited access to healthcare and specialized care.
The study found that racial disparities in kidney transplantation persist despite advances in the field. Blacks are more likely to develop kidney failure but less likely to undergo transplantation, particularly from living donors.
A new international study documents the physiology of dying and confirms that death is an irreversible process. The DePPaRT study found that cardiac activity often stops and restarts several times during the dying process, but no one regained sustained circulation or consciousness. This provides evidence to support the current standard...
