Risk of cardiovascular disease in elderly subjects with obesity and liver fibrosis and the potential benefit of statin treatment.
Liver fibrosis progression is influenced by older age and cardiometabolic risk factors such as obesity and is associated with an increased risk of cardiovascular events. While statins may protect against cardiovascular complications, their effects in elderly individuals with obesity and liver fibrosis are unclear. ⋯ Elderly individuals with obesity and liver fibrosis are at higher risk for (non-)fatal stroke, which is reduced with pravastatin. Pravastatin also potentially lowers all-cause mortality in subjects with lean weight and liver fibrosis.

Linear metrics for ventricular volume play a large role in the rapid, approximate evaluation of ventricular volume. In this article, we automatically extract linear measures of ventricular volume to explore their correlation with lateral ventricular volume (LVV) in the healthy adult population and comprehensively define normal values. ⋯ ALVI is a newer index with strong correlation with LVV and has strong potential for clinical use. Both FOHR and ER show moderate correlation with LVV. Reference values for linear estimates of ventricular volume may help clinicians better identify patients with pathological ventriculomegaly.

Renal ischemia-reperfusion injury (IRI) is a prevalent clinical syndrome, yet its underlying pathogenesis remains largely unknown. Aldehyde dehydrogenase 2 (ALDH2), an enzyme responsible for detoxifying lipid aldehydes, has been suggested to play a protective role against IRI. In our study, we observed that Aldh2 knock-out C57BL/6 mice experienced more severe renal functional impairment following IRI. ⋯ ALDH2 specifically interacts with the N-terminal domain of NCOR1, which is responsible for its interaction with its E3 ligase SIAH2. This interaction inhibits the proteasome degradation of NCOR1, ultimately stabilizing the NCOR1 transcriptional repression complex. In summary, our research uncovers the role of ALDH2 in mitigating renal IRI by inhibiting 20-HETE synthesis through the transcriptional repression of Cyp4a.
