[Experience of a Rapid Diagnostic and Short Stay Unit implemented in Argentina].

Introduction: Rapid diagnostic units (RDUs) represent an alternative to conventional hospitalization diagnosis, enabling outpatient care for patients with suspected potentially severe disease. The first year of operation of a Rapid Diagnostic and Short Stay Unit (RDSSU) is described.

Materials And Methods: Retrospective study involving 696 patients, documenting 739 events defined as each patient's entry into the RDU for specific reasons.

Application of Surface Stress-Driven Model for Higher Vibration Modes of Functionally Graded Nanobeams.

This paper employs a surface stress-driven nonlocal theory to investigate the synergistic impact of long-range interaction and surface energy on higher vibration modes of Bernoulli-Euler nanobeams made of functionally graded material. It takes into account surface effects such as the surface modulus of elasticity, residual surface stresses, surface density, and rotary inertia. The governing equation is derived through the application of Hamilton's principle.

Defects in lysosomal function and lipid metabolism in human microglia harboring a TREM2 loss of function mutation.

TREM2 is an innate immune receptor expressed by microglia in the adult brain. Genetic variation in the TREM2 gene has been implicated in risk for Alzheimer's disease and frontotemporal dementia, while homozygous TREM2 mutations cause a rare leukodystrophy, Nasu-Hakola disease (NHD). Despite extensive investigation, the role of TREM2 in NHD pathogenesis remains poorly understood.
