Comparative analysis of extracellular vesicles miRNAs (EV-miRNAs) and cell-free microRNAs (cf-miRNAs) reveals that EV-miRNAs are more promising as diagnostic and prognostic biomarkers for prostate cancer.

MicroRNAs can be found intracellularly incorporated into extracellular vesicles (EV-miRNAs) or extracellularly as cell-free miRNAs (cf-miRNAs). This study aimed to compare the diagnostic and prognostic potential of four miRNAs with recognized roles in prostate cancer as cf-miRNAs and EV-miRNAs, obtained from liquid biopsies (LB). Total RNA was isolated from whole plasma and plasma EVs from 15 controls (CTR) and 30 patients (20 with localized prostate cancer (PCa), 10 with metastatic prostate cancer (mPCa)).

This was reaffirmed by the EULAR/ACR in 2019, emphasizing the importance of renal biopsy in LN. However, the current classification lacks specific histopathological criteria for defining LN.

Article Synopsis
- * Among 94 patients, most were male and half had a history of hypertension; commonly observed kidney issues included collapsing glomerulopathy (CG), focal segmental glomerulosclerosis (FSGS), and thrombotic microangiopathy (TMA).
- * Results indicated that FSGS and minimal change disease (MCD) were linked to better kidney survival compared to TMA, underscoring differences in kidney complications resulting from COVID-19 within this patient group.
Article Synopsis
- The study explores the effects of Angiotensin-II and inflammation pathways on aging nephropathy, particularly their role in chronic kidney disease progression.
- Researchers tested Losartan alone and in combination with the NF-κB inhibitor PDTC on aging rats to see if these treatments could alleviate kidney damage.
- Results indicated that while Losartan showed some benefits, the combination of Losartan and PDTC effectively prevented kidney abnormalities, suggesting a potential new treatment strategy for age-related kidney decline.
Cost-effectiveness of radiofrequency ablation versus percutaneous ethanol injection for early hepatocellular carcinoma in a resource-poor setting: a randomized trial.
Einstein (Sao Paulo)
October 2024
Objective: This study assessed the cost-effectiveness of radiofrequency ablation compared with percutaneous ethanol injection in patients with early hepatocellular carcinoma in relation to the objective response rate and costs related to the procedure.
Methods: This was a prospective single-center randomized trial. The primary outcome was cost-effectiveness.
