RESUMEN
BACKGROUND: Survivorship care plans (SCPs) summarize patients' treatment and act as an education and communication tool between oncologists and primary care providers (PCPs). But creation and delivery of SCPs are challenging, labor intensive, and costly. The University of New Mexico Comprehensive Cancer Center (UNM CCC) treats a poor, rural, and minority patient population, and our purpose was to implement and evaluate a process to create and deliver SCPs to patients and PCPs. METHODS: Providers placed an electronic SCP order, basic information was imported, and staff compiled treatment details. Flagged SCPs were then ready for delivery, providers approved of and delivered the SCP at the next encounter, and the SCP was sent to the PCP. RESULTS: By April 2020, 283 SCPs were ordered, 241 (85.2%) were created by the designated staff, and 97 (34.2%) were given to patients after definitive therapy for breast cancer (59.1%), gynecological cancers (10.8%), prostate cancer (7.4%), colorectal cancer (5.1%), and lymphomas (4.8%). Of 97 SCPs eligible to be sent to PCPs, 75 (77.3%) were mailed or sent via EMR. Of the 41 (48.9%) SCPs sent via mail or fax, only 8 (8.3%) were received and 5 (5.2%) integrated. CONCLUSIONS: This study shows that SCPs can be delivered to patients in a poor, rural, and minority patient population but that PCP receipt and integration of SCPs are poor. Future efforts need to ensure that an oncologist to PCP education and communication tool is able reach and be integrated by PCPs.

We have assessed the efficacy of the recently developed CRISPR/Cas (clustered regularly interspaced short palindromic repeats/CRISPR-associated) system for genome modification in the amphibian Xenopus tropicalis. As a model experiment, targeted mutations of the tyrosinase gene were verified, showing the expected albinism phenotype in injected embryos. We further tested this technology by interrupting the six3 gene, which is required for proper eye and brain formation. Expected eye and brain phenotypes were observed when inducing mutations in the six3 coding regions, as well as when deleting the gene promoter by dual targeting. We describe here a standardized protocol for genome editing using this system. This simple and fast method to edit the genome provides a powerful new reverse genetics tool for Xenopus researchers.

BACKGROUND: Activity of the Transforming growth factor-ß (TGFß) pathway is essential to the establishment of body axes and tissue differentiation in bilaterians. Orthologs for core pathway members have been found in all metazoans, but uncertain homology of the body axes and tissues patterned by these signals raises questions about the activities of these molecules across the metazoan tree. We focus on the principal canonical transduction proteins (R-Smads) of the TGFß pathway, which instruct both axial patterning and tissue differentiation in the developing embryo. We compare the activity of R-Smads from a cnidarian (Nematostella vectensis), an arthropod (Drosophila melanogaster), and a vertebrate (Xenopus laevis) in Xenopus embryonic assays. RESULTS: Overexpressing NvSmad1/5 ventralized Xenopus embryos when expressed in dorsal blastomeres, similar to the effects of Xenopus Smad1. However, NvSmad1/5 was less potent than XSmad1 in its ability to activate downstream target genes in Xenopus animal cap assays. NvSmad2/3 strongly induced general mesendodermal marker genes, but weakly induced ones involved in specifying the Spemann organizer. NvSmad2/3 was unable to induce a secondary trunk axis in Xenopus embryos, whereas the orthologs from Xenopus (XSmad2 and XSmad3) and Drosophila (dSmad2) were capable of doing so. Replacement of the NvSmad2/3 MH2 domain with the Xenopus XSmad2 MH2 slightly increased its inductive capability, but did not confer an ability to generate a secondary body axis. CONCLUSIONS: Vertebrate and cnidarian Smad1/5 have similar axial patterning and induction activities, although NvSmad1/5 is less efficient than the vertebrate gene. We conclude that the activities of Smad1/5 orthologs have been largely conserved across Metazoa. NvSmad2/3 efficiently activates general mesendoderm markers, but is unable to induce vertebrate organizer-specific genes or to produce a secondary body axis in Xenopus. Orthologs dSmad2 and XSmad3 generate a secondary body axis, but activate only low expression of organizer-specific genes that are strongly induced by XSmad2. We suggest that in the vertebrate lineage, Smad2 has evolved a specialized role in the induction of the embryonic organizer. Given the high level of sequence identity between Smad orthologs, this work underscores the functional importance of the emergence and fixation of a few divergent amino acids among orthologs during evolution.
