Park7 deletion leads to sex-specific transcriptome changes involving NRF2-CYP1B1 axis in mouse midbrain astrocytes.

Loss-of-function mutations in PARK7, encoding for DJ-1, can lead to early onset Parkinson's disease (PD). In mice, Park7 deletion leads to dopaminergic deficits during aging, and increased sensitivity to oxidative stress. However, the severity of the reported phenotypes varies.

Barriers to early detection: Insurance denials for breast MRI screening in women with germline BRCA1/2 mutations.

Objectives: Women with germline BRCA1/2 pathogenic variants (gBRCA1/2) are recommended to undergo annual breast MRI and mammography. Our objective was to describe the frequency of insurance denials for annual breast MRIs in women with gBRCA1/2 and determine denial trends.

Methods: Women with gBRCA1/2 following in a high-risk breast cancer clinic with breast MRIs ordered from 2020 to 2021 were identified and cross-referenced with a database of insurance denials.

Clinical Manifestations.

Background: Hispanics are disproportionately affected by Alzheimer's disease and related dementias (ADRD) when compared to non-Hispanic Whites (NHW). Previous studies have shown that neuropsychiatric symptoms can further exacerbate clinical functioning among ADRD patients, leading to increase in caregiver burden and poorer quality of life. However, most studies in this area have focused on predominately Caucasian samples, and relationships between emotional and clinical functioning among Hispanic older adults at risk of ADRD are poorly understood.

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.
