Impact of a pulmonary embolism response team initiative on hospital mortality of patients with bilateral pulmonary embolism.

Introduction: Pulmonary embolism (PE) response teams (PERT) for the management of high-risk PE (HR-PE) and intermediate-high risk PE (IHR-PE) are encouraged in PE guidelines. We aimed to assess the impact of a PERT initiative on mortality in these groups of patients, compared with standard care.

Methods: We conducted a prospective, single-center registry, including consecutive patients with HR-PE and IHR-PE with PERT activation from February-2018 to December-2020 (PERT group, n=78 patients) and compared it with an historic cohort of patients admitted to our hospital in a previous 2-year period (2014-2016), managed with standard of care (SC-group, n=108 patients).

Impact of delirium in acute cardiac care unit after transcatheter aortic valve replacement.

Background: Delirium is a cognitive disorder that commonly occurs during hospitalization in acute cardiac care units (ACCU), but its effect after transcatheter aortic valve replacement (TAVR) has not been well evaluated. The objective of this study is to determine the incidence, predictive factors and prognostic impact of delirium following TAVR.

Methods: A total of 501 consecutive patients admitted to an ACCU after TAVR were included.

Recombinant Protein-Based Nanoparticles: Elucidating their Inflammatory Effects In Vivo and their Potential as a New Therapeutic Format.

Bacterial inclusion bodies (IBs) are protein-based nanoparticles of a few hundred nanometers formed during recombinant protein production processes in different bacterial hosts. IBs contain active protein in a mechanically stable nanostructured format that has been broadly characterized, showing promising potential in different fields such as tissue engineering, protein replacement therapies, cancer, and biotechnology. For immunomodulatory purposes, however, the interference of the format immunogenic properties-intrinsic to IBs-with the specific effects of the therapeutic protein is still an uncovered gap.

AFM and Microrheology in the Zebrafish Embryo Yolk Cell.

Elucidating the factors that direct the spatio-temporal organization of evolving tissues is one of the primary purposes in the study of development. Various propositions claim to have been important contributions to the understanding of the mechanical properties of cells and tissues in their spatiotemporal organization in different developmental and morphogenetic processes. However, due to the lack of reliable and accessible tools to measure material properties and tensional parameters in vivo, validating these hypotheses has been difficult.

Standardized Nanomechanical Atomic Force Microscopy Procedure (SNAP) for Measuring Soft and Biological Samples.

We present a procedure that allows a reliable determination of the elastic (Young's) modulus of soft samples, including living cells, by atomic force microscopy (AFM). The standardized nanomechanical AFM procedure (SNAP) ensures the precise adjustment of the AFM optical lever system, a prerequisite for all kinds of force spectroscopy methods, to obtain reliable values independent of the instrument, laboratory and operator. Measurements of soft hydrogel samples with a well-defined elastic modulus using different AFMs revealed that the uncertainties in the determination of the deflection sensitivity and subsequently cantilever's spring constant were the main sources of error.
