At the present time, the number of deceased donor kidney transplants performed annually has remained unchanged for 4 years. Desire for standard criteria donor (SCD) kidneys by recipients, coupled with high discard rates of donor kidneys, contributes to a lack of procedures being performed. A subgroup of recipients, those under age 50, may fare as well with an expanded criteria donor (ECD) allograft as those who receive an SCD kidney. The use of ECD allografts in recipients over 50 years of age, while projected to have poorer allograft survival than that produced with an SCD graft, still results in better recipient survival than patients who have elected to remain on dialysis.

Baseline Imaging Derived Factors of Response Following [225Ac]Ac-J591 Therapy in Metastatic Castration-Resistant Prostate Cancer: A Lesion Level Analysis.
Prostate
January 2025
Department of Urology, Weill Cornell Medicine, New York City, New York, USA.
Purpose: Actinium-225 labeled prostate-specific membrane antigen (PSMA) targeted radionuclide therapy has emerged as a potential treatment option in the management of men with metastatic castrate-resistant prostate cancer (mCRPC). This study investigated molecular imaging-derived parameters and compared imaging response of lesions categorized by tumor site.
Methods: Men with mCRPC treated with [225Ac]Ac-J591 from 2017 to 2022 at our center on two prospective trials (NCT03276572 and NCT04506567) with pre- and post-treatment [68Ga]Ga-PSMA-11 Positron Emission Tomography (PET) imaging studies available were included.

Purpose Of Review: Recent advancements in genetic engineering have propelled the field of xenotransplantation from preclinical models to early compassionate use cases. As first-in-human clinical trials (FIHCTs) approach, we examine recent developments, ethical and regulatory challenges, immunological considerations, and the clinical infrastructure necessary for successful xenotransplantation trials.

Donation after circulatory death is helping to expand the donor pool for heart transplantation. Nevertheless, these hearts are more susceptible to myocardial edema and decision of accepting the organ can be a challenge for the heart transplant team. Hemodynamic and echocardiographic criteria are used routinely, but there is still a lack of strong evidence that supports the decision-making in particular situations.

Background: Despite many years of investigation into mesenchymal stem cells (MSCs) and their potential for treating inflammatory conditions such as COVID-19, clinical outcomes remain variable due to factors like donor variability, different tissue sources, and diversity within MSC populations. Variations in MSCs' secretory and proliferation profiles, and their proteomic and transcriptional characteristics significantly influence their therapeutic potency, highlighting the need for enhanced characterization methods to better predict their efficacy. This study aimed to evaluate the biological characteristics of MSCs from different tissue origins, selecting the most promising line for further validation in a K18-hACE2 mouse model of SARS-CoV-2 infection.

Department of Medical Education, Medical School, Jeonbuk National University, Jeonju, Republic of Korea.
Background: Cadaveric dissection is an essential practice for medical students to understand human anatomy and internalize professional attitudes toward death, such as empathy and respect for the deceased. Previous studies have focused on emotional responses such as shock, anxiety, and fear at the start of dissection practice. However, limited research exists on students' reflective thinking and perceptions before practice.
