Routine cold storage leads to hyperacute graft loss in pig-to-primate kidney xenotransplantation; hypothermic machine perfusion may be preferred preservation modality in xenotransplantation.

Xenotransplantation (XTx) is an increasingly realistic solution to the organ shortage. Clinical XTx may require off-site procurement in a designated pathogen free (DPF) facility necessitating a period of cold ischemic time during transportation. This study evaluates the impact of different kidney preservation strategies on early graft function in pig-to-baboon XTx in a series of eight cases of pig-to-baboon xenotransplantation performed after five hours of cold ischemic time and compares these results to six cases of pig-to-baboon xenotransplantation performed with minimal ischemic time.

Deep learning for diagnosis of acute promyelocytic leukemia via recognition of genomically imprinted morphologic features.

Acute promyelocytic leukemia (APL) is a subtype of acute myeloid leukemia (AML), classified by a translocation between chromosomes 15 and 17 [t(15;17)], that is considered a true oncologic emergency though appropriate therapy is considered curative. Therapy is often initiated on clinical suspicion, informed by both clinical presentation as well as direct visualization of the peripheral smear. We hypothesized that genomic imprinting of morphologic features learned by deep learning pattern recognition would have greater discriminatory power and consistency compared to humans, thereby facilitating identification of t(15;17) positive APL.
