QOLP-35. PEDIATRIC POST-MORTEM TISSUE DONATION DURING A PANDEMIC: A MODEL OF COLLABORATION

BACKGROUND Obtaining post-mortem tissue from pediatric oncology patients is not only critical to research, but studies show that participating in the process can also help grieving families heal. Since 2019, the national Gift from a Child program — a multi-institutional effort to increase the rate of rapid autopsies for pediatric CNS tumor patients — has made significant progress. Collecting high-quality post-mortem tissue has advanced research through cell line generation and genomic analyses. Unfortunately, some autopsy programs temporarily shut down during the COVID-19 pandemic. METHODS We retrospectively reviewed autopsies of four patients treated at Memorial Sloan Kettering (MSK) who underwent limited brain post-mortem examination at Weill Cornell Medicine College (WCMC) from June 2020 to June 2021. We collected patient demographics; DNR status; time of death and procedure; restrictions due to the COVID-19 pandemic; and results of the tissue analysis. Each case presented unique challenges and the timing of securing parental consent varied. RESULTS Three of four specimens were processed within 12 hours of the time of death. Two Spanish-speaking families required interpreters services to obtain consent. In all cases tumor aliquots were flash frozen for further study. All specimens contained viable tumor and cell line generation was successful in one case. All families/caregivers expressed gratitude for the opportunity to participate and for the handling of the procedures. DISCUSSION Despite the sensitive nature of these cases, clinicians should offer the option of a rapid autopsy to caregivers of pediatric patients based on the scientific need and the positive effect it has on grieving families. This paper outlines the logistical efforts required for these donations to take place and provides a framework for providers to offer rapid autopsy as an option for families through this program.

Isolation in Natural Host Cell Lines of Wolbachia Strains wPip from the Mosquito Culex pipiens and wPap from the Sand Fly Phlebotomus papatasi

Endosymbiotic intracellular bacteria of the genus Wolbachia are harboured by many species of invertebrates. They display a wide range of developmental, metabolic and nutritional interactions with their hosts and may impact the transmission of arboviruses and protozoan parasites. Wolbachia have occasionally been isolated during insect cell line generation. Here, we report the isolation of two strains of Wolbachia, wPip and wPap, during cell line generation from their respective hosts, the mosquito Culex pipiens and the sand fly Phlebotomus papatasi. wPip was pathogenic for both new C. pipiens cell lines, CPE/LULS50 and CLP/LULS56, requiring tetracycline treatment to rescue the lines. In contrast, wPap was tolerated by the P. papatasi cell line PPL/LULS49, although tetracycline treatment was applied to generate a Wolbachia-free subline. Both Wolbachia strains were infective for a panel of heterologous insect and tick cell lines, including two novel lines generated from the sand fly Lutzomyia longipalpis, LLE/LULS45 and LLL/LULS52. In all cases, wPip was more pathogenic for the host cells than wPap. These newly isolated Wolbachia strains, and the novel mosquito and sand fly cell lines reported here, will add to the resources available for research on host–endosymbiont relationships, as well as on C. pipiens, P. papatasi, L. longipalpis and the pathogens that they transmit.

GENRE CHARACTERISTICS OF AUTOBIOGRAPHIC POEM BY B. SHAKHOVSKY "SCORN YOUTH"

The article examines B. Shakhovsky's “Scorched Youth” from the point of view of the problem of genre identification. According to the observations of the authors of the study, the work of the Astrakhan artist of the word is an autobiographical poem, in the center of which is a lyrical hero, pulling together all the paradigms of the text. It is concluded that B. Shakhovsky's poem is an organic unity of the lyrical and the epic. The article defines the mechanisms of plot building and compositional organization of the text. The authors of the article argue that the autobiography of the lyric-epic work of the Astrakhan poet is combined with a monumental epoch-making: the life of the lyrical character repeats the history of the fate of the front-line generation.
