Aggressive Lymphoma after CD19 CAR T-Cell Therapy.

The development of a fatal, clonal, autonomously proliferating CD4-CD8- chimeric antigen receptor (CAR)+ peripheral T-cell lymphoma (PTCL) occurred 1 month after a patient received treatment with tisagenlecleucel for relapsed primary central nervous system lymphoma. The PTCL had a clonal T-cell receptor rearrangement, which was already detectable in the apheresis product for CAR T-cell manufacturing and 7 months earlier for autologous transplantation. Somatic and mutations in CD34+ stem cells and their progeny were detected in the PTCL, in the apheresis specimen that was obtained for CAR T-cell production, and in the autotransplant.

A family-centric, comprehensive nurse-led home oxygen programme for neonatal chronic lung disease: home oxygen policy evaluation (HOPE) study.

Objectives: Considerable variation and little objective evidence exists to guide the use of supplemental oxygen therapy in infants with neonatal chronic lung disease (nCLD) after hospital discharge. We developed a new policy utilizing regular oximetry downloads to help determine commencement and titration of low flow oxygen. The aim of this policy is to improve safety and uniformity in practice and potentially lead to improvements in outcomes including the number of infants being discharged on home oxygen therapy (HOT) and length of stay (LOS).

Psychosocial Needs of People Living With Pleural Mesothelioma and Family Carers: A Mixed Methods Study.

Background: Mesothelioma is a cancer of growing global incidence, especially in developing countries, with unique complex psychosocial impacts on patients and their carers.

Aims: To provide a comprehensive understanding of the psychosocial needs of people living with pleural mesothelioma and family carers.

Methods: A mixed methods design with 61 semi-structured interviews and psychometrically validated questionnaires to assess pleural mesothelioma patients' (n = 36) quality of life and frailty and carers' (n = 25) caregiving experiences, quality of life, and pre-loss prolonged grief symptoms.

COVID-19 lineages in a minimally vaccinated island population: Genomic epidemiology of SARS-CoV-2 in Haiti.

We monitored SARS-CoV-2 variants in Haiti from 2020-2023. Despite Haitian COVID-19 travel restrictions and in the setting of a vaccination rate of 2.7%, the timing and lineage evolution of the Haiti epidemic mirrored what was occurring in the rest of the world.
