JAMA network open

Song MK, Manatunga A, Plantinga L, Metzger M, Kshirsagar AV +6 more

Plain English
This study looked at how effective an advance care planning program was for patients on dialysis and their family members when making end-of-life decisions. The program, conducted in 42 dialysis clinics, showed that those who participated felt more aligned in their goals for care and experienced less decision-making stress, with meaningful improvements indicated by specific measures (for example, patient-decision conflict scores improved by -0.10). While the program helped prepare families better, it had mixed results on emotional well-being after losing a loved one. Who this helps: This benefits patients on dialysis and their families.

Retention of Human iPSC-Derived or Primary Cells Following Xenotransplantation into Rat Immune-Privileged Sites.

2023

Bioengineering (Basel, Switzerland)

Später T, Kaneda G, Chavez M, Sheyn J, Wechsler J +6 more

Plain English
This study looked at how well human cells, specifically induced pluripotent stem cell-derived mesenchymal stromal cells (iMSCs) and primary nucleus pulposus cells (NPCs), survive when transplanted into the knee joints and intervertebral discs of rats with different immune systems. Researchers found that both types of rats (immune-compromised and normal) had low inflammation responses and no significant difference in the number of recovered human cells after 7 to 14 days. This finding is important because it suggests that using normal immune system rats for future studies on human cell transplants could be effective and carry similar results to those seen in more vulnerable rats. Who this helps: This helps researchers and doctors working on cell-based therapies for conditions like arthritis and spinal disorders.

Fluids and barriers of the CNS

Haferkamp U, Hartmann C, Abid CL, Brachner A, Höchner A +12 more

Plain English
This research examined how different types of brain cells influence the blood-brain barrier (BBB), particularly in late-onset Alzheimer's disease (LOAD). The study found that certain brain cells, especially neural stem cells, help strengthen the BBB and support its proper function, but this support weakens in the presence of LOAD—specifically, the neural stem cells had the biggest positive impact on the BBB. Understanding these interactions is important because it could lead to new treatments that protect the brain from damage in Alzheimer's patients. Who this helps: This benefits patients with late-onset Alzheimer's disease and their caregivers.

Clinical kidney journal

Michon-Colin A, Metzger M, Bankir L, Gauci C, Brunel M +12 more

Plain English
This study looked at two substances in the blood—fibroblast growth factor 23 (iFGF23) and copeptin—to see how they relate to kidney failure and death in patients with chronic kidney disease (CKD). Researchers found that higher levels of iFGF23 were strongly linked to worse outcomes, showing that patients with higher levels had a 2.72 times greater risk of kidney failure or death compared to those with lower levels. In contrast, copeptin did not show a significant association. This is important because it suggests that measuring iFGF23 could help monitor CKD patients more effectively. Who this helps: This benefits patients with chronic kidney disease and their doctors.
