Performance of the VITEK® MS system for the identification of filamentous fungi in a microbiological laboratory in Chile.

Filamentous fungi are an emergent cause of severe infections in immunocompromised patients. Timely and accurate identification is crucial to initiate appropriate therapy. Traditional identification methods are time-consuming, labor-intensive, and operator-dependent.

Salmonella enterica Serovar Abony Outbreak Caused by Clone of Reference Strain WDCM 00029, Chile, 2024.

A Salmonella enterica serovar Abony outbreak occurred during January-April 2024 in Chile. Genomic evidence indicated that the outbreak strain was a clone of reference strain WDCM 00029, which is routinely used in microbiological quality control tests. When rare or unreported serovars cause human infections, clinicians and health authorities should request strain characterization.

Deconstruction of a memory engram reveals distinct ensembles recruited at learning.

How are associative memories formed? Which cells represent a memory, and when are they engaged? By visualizing and tagging cells based on their calcium influx with unparalleled temporal precision, we identified non-overlapping dorsal CA1 neuronal ensembles that are differentially active during associative fear memory acquisition. We dissected the acquisition experience into periods during which salient stimuli were presented or certain mouse behaviors occurred and found that cells associated with specific acquisition periods are sufficient alone to drive memory expression and contribute to fear engram formation. This study delineated the different identities of the cell ensembles active during learning, and revealed, for the first time, which ones form the core engram and are essential for memory formation and recall.

Long-Term Performance and Safety of a Superficial HA Filler With Tri-Hyal Technology on Different Facial Zones: Forehead, Cheeks, Crow's Feet, and Upper Lips.

Background: The function of injectable hyaluronic acid-based fillers is to smooth dermal wrinkles formed during aging. The aim of this study is to evaluate the performance and safety of a dermal filler after its commercialization.

Methods: In this context, an 18-month prospective randomized single-blind study for the efficacy and safety of ART FILLER Fine Lines (AFFL) was performed on the forehead, the upper lip, the cheek folds, and the crow's feet.

Parametrization of the dying brain: A case report from ICU bed-side EEG monitoring.

Background: Cortical high-frequency activation immediately before death has been reported, raising questions about an enhanced conscious state at this critical time. Here, we analyzed an electroencephalogram (EEG) from a comatose patient during the dying process with a standard bedside monitor and spectral parameterization techniques.

Methods: We report neurophysiologic features of a dying patient without major cortical injury.
