Circularity in polydiketoenamine thermoplastics via control over reactive chain conformation.

Controlling the reactivity of bonds along polymer chains enables both functionalization and deconstruction with relevance to chemical recycling and circularity. Because the substrate is a macromolecule, however, understanding the effects of chain conformation on the reactivity of polymer bonds emerges as important yet underexplored. Here, we show how oxy-functionalization of chemically recyclable condensation polymers affects acidolysis to monomers through control over distortion and interaction energies in the rate-limiting transition states.

Medical and Surgical Episodes Among Hospital Participants in the Bundled Payments for Care Improvement-Advanced Program.

Importance: Hospital participation in the Bundled Payments for Care Improvement-Advanced (BPCI-A) initiative has been associated with modest savings and stable clinical outcomes overall, but it is unknown whether the program performs differently for medical and surgical or procedural (henceforth, surgical) episodes.

Objective: To assess the association of BPCI-A participation with Medicare spending and clinical outcomes for medical and surgical episodes.

Design, Setting, And Participants: This retrospective difference-in-differences cohort study utilized 100% Medicare fee-for-service inpatient claims for episodes initiated between January 1, 2017, and September 30, 2019, and included 90 days of follow-up.

Health-Related Values Discussions with Patients Undergoing Allogeneic and Autologous Stem Cell Transplant: Feasibility and Acceptability of an Early Primary Palliative Care Intervention.

Background: Hematopoietic stem cell transplant (HSCT) has curative potential but also relatively high morbidity and mortality. Patients have multidimensional palliative care (PC) needs throughout the transplant process. However, PC is not routinely offered to patients with hematologic malignancies.
