Extracellular Vesicles and Tunnelling Nanotubes as Mediators of Prostate Cancer Intercellular Communication.

Prostate cancer (PCa) pathogenesis relies on intercellular communication, which can involve tunnelling nanotubes (TNTs) and extracellular vesicles (EVs). TNTs and EVs have been reported to transfer critical cargo involved in cellular functions and signalling, prompting us to investigate the extent of organelle and protein transfer in PCa cells and the potential involvement of the androgen receptor. Using live cell imaging microscopy, we observed extensive formation of TNTs and EVs operating between PCa, non-malignant, and immune cells.

ENHANCEMENT OF CIRRHOSIS MORTALITY PREDICTION BY INCLUDING HEPATIC ENCEPHALOPATHY TO MELD3.0 IN A NATIONAL VETERAN COHORT.

Despite negative outcomes, hepatic encephalopathy (HE) is not included in model-for-end-stage liver disease (MELD) scores, including MELD3.0. In a national Veterans affairs (VA) database, we studied the additive mortality predictive impact of a documented inpatient overt HE diagnosis on MELD3.

LGBTQ+ status and sex of record in Veterans with post-traumatic stress disorder: demographics, comorbidities, and outpatient encounters.

Objectives: This study aims to analyze differences between lesbian, gay, bisexual, transgender, and queer (LGBTQ+) and non-LGBTQ+ Veterans with post-traumatic stress disorder (PTSD) in terms of demographics, comorbidities, and medical care usage, including differences by sex of record, including separate analyses for transgender and non-transgender Veterans.

Methods: Chi-square, -test, ANOVA Welch one-way testing, and absolute standardized difference analyses were conducted on a cohort of 277,539 Veterans diagnosed with PTSD.

Results: The study found significant differences, particularly concerning positive LGBTQ+ status and sex of record.

Disparities in Alcohol-Associated Liver Disease Hospital Encounters Amongst a Texas-Based Cohort of Patients.

Introduction: Alcohol-associated liver disease (ALD) disproportionately impacts men, racial and ethnic minorities, and individuals of low socioeconomic status; however, it's unclear how recent increases in ALD burden have impacted these disparities. We aimed to describe trends in racial, ethnic and socioeconomic disparities in alcohol-associated hospital encounters.

Methods: We conducted a retrospective cohort study of adult hospital encounters with alcohol-associated diagnoses from three health systems between January 2016 and December 2021.

Components of the Endosome-Lysosome Vesicular Machinery as Drivers of the Metastatic Cascade in Prostate Cancer.

Prostate cancer remains a significant global health concern, with over 1.4 million new cases diagnosed and more than 330,000 deaths each year. The primary clinical challenge that contributes to poor patient outcomes involves the failure to accurately predict and treat at the onset of metastasis, which remains an incurable stage of the disease.
