Since early 2020, the onset of the COVID-19 pandemic, physicians have continued to report adverse events associated with care. Patients also continued to participate in the hospital satisfaction surveys. To date, no study in France has measured the impact of the pandemic on adverse events and patient satisfaction.

Mixed Copolymer Adlayers Allowing Reversible Thermal Control of Single Cell Aspect Ratio.

Dynamic guidance of living cells is achieved by fine-tuning and spatiotemporal modulation on artificial polymer layers enabling reversible peptide display. Adjustment of surface composition and interactions is obtained by coadsorption of mixed poly(lysine) derivatives, grafted with either repellent PEG, RGD adhesion peptides, or T-responsive poly(N-isopropylacrylamide) strands. Deposition of mixed adlayers provides a straightforward mean to optimize complex substrates, which is here implemented to achieve (1) thermal control of ligand accessibility and (2) adjustment of relative adhesiveness between adjacent micropatterns, while preserving cell attachment during thermal cycles.
