Regional disparities in the management and outcomes of ST-elevation myocardial infarction: an Italian analysis focusing on time-dependent reperfusion networks and in-hospital logistics.

Background: Prompt reperfusion is critical for patients with ST-segment elevation myocardial infarction (STEMI) to improve outcomes. Yet, variability in regional healthcare delivery may influence treatment times and patient outcomes. We thus aimed at evaluating differences in management and outcomes of STEMI patients across Northern, Central, and Southern Italy, focusing on time-dependent reperfusion and in-hospital logistics.

Tolerability and Preliminary Outcomes of Adjuvant T-DM1 in HER2-Positive Breast Cancer After Neoadjuvant Therapy: The ATD Study.

Background/objectives: HER2-positive breast cancer (HER2BC) is an aggressive subtype, with neoadjuvant treatment (NAT) aiming to achieve a pathological complete response (pCR) to improve long-term outcomes. Trastuzumab emtansine (T-DM1) has been established as the standard of care in the adjuvant setting for HER2BC patients who do not obtain pCR. The ATD study aimed to evaluate the real-world tolerability of T-DM1 in this setting.

Characterization of bovine serum albumin immobilization on surface modified glass slides in case of pyro-electrohydrodynamic spots.

Background: Pyro-electrohydrodynamic jetting (p-jet) has emerged recently as a promising technique for biosensing applications, through the concentration of highly diluted biomolecules in fluorescent spots at microscale. However, a great challenge still remains in optimizing the binding strategy for the sensing interface, enabling the detection of low abundance proteins through immunofluorescence protocols. Indeed, the surface of reaction can be functionalized with different chemical groups able to bind the target molecule with a strong interaction, prior to the p-jet spots decreasing the possibility to lose sensitivity after the common rinsing steps.

Sensitive colorimetric immunosensor using AuNP-functionalized polymer film for picogram-level detection of Tau protein intermediate aggregates.

Here we demonstrate for the first time that an antibody-gold nanoparticles (AuNPs)-polymer conjugate thin-film biosensor can easily be fabricated to selectively capture Tau protein. Gold nanoparticles (AuNPs) are employed as sensing elements, thus capitalizing on their propensity to undergo assembly or disassembly in response to the adsorption or conjugation of various biomolecules on their surface, thereby forming robust interactions with the target analyte. We show that the Tau protein in its different aggregation phases can be detected, by restricting the reaction area on the solid thin polymer film and thus reducing the diffusion effects usually encountered in immunosensors.
