Vasohibin-1 (VASH-1) is a negative feedback regulator of angiogenesis, and a small vasohibin-binding protein (SVBP) serves as its secretory chaperone and contributes to its antiangiogenic effects. In the present study, we aimed to define the clinical significance of VASH-1 and SVBP in patients with chronic kidney disease (CKD). We recruited 67 Japanese hospitalized patients with renal disorders with (n = 45) or without (n = 22) renal biopsy samples and 10 Japanese healthy controls. We evaluated the correlations between the plasma and urinary levels of VASH-1/VASH-1-SVBP complex/SVBP and the clinicopathological parameters. The plasma levels of VASH-1 were inversely correlated with age and systolic and diastolic blood pressure and positively correlated with crescent formation. Increased plasma and urinary levels of VASH-1 and VASH-1-SVBP complex were significantly correlated with worse renal outcomes. These results demonstrate an association between elevated urinary and plasma levels of VASH-1 and progressive decline of the renal function, thus suggesting a potential role for VASH-1 in predicting a worse renal prognosis in patients with renal disease, including CKD.

Importance: Apolipoprotein B (apoB) distribution and its implications as an atherosclerotic cardiovascular disease (ASCVD) risk-enhancing factor among individuals of diverse Hispanic or Latino backgrounds have not been described.
Objective: To describe the distribution of apoB in the Hispanic Community Health Study/Study of Latinos (HCHS/SOL) cohort and to characterize associations of baseline sociodemographic and clinical variables with apoB and self-identified Hispanic or Latino background.
Design, Setting, And Participants: The HCHS/SOL was a prospective, population-based cohort study of diverse Hispanic or Latino adults living in the US who were recruited and screened between March 2008 and June 2011.

The enzyme dihydropyrimidine dehydrogenase (DPD) is the primary catabolic pathway of fluoropyrimidines including 5 fluorouracil (5FU) and capecitabine. Cases of lethal toxicity have been reported in cancer patients with complete DPD deficiency receiving standard dose of 5FU or capecitabine. DPD is encoded by the pharmacogene DPYD in which more than 200 variants have been identified.

Background: Prostate cancer therapy with surgical or chemical castration with GnRH agonists has been linked to elevated FSH levels, which may contribute to secondary health disorders, including atherosclerosis and diabetes. Although recent findings suggest a role for FSH beyond the reproductive system, its metabolic impact remains unclear and difficult to disentangle from that of androgens. In this study, we examined the metabolic changes induced by FSH and distinguished them from those caused by testosterone.

Extracellular vesicles (EVs) emerged as critical contributors to the pathogenesis of vascular endothelial barrier dysfunction during the inflammatory response to infection. However, the contribution of circulating EVs to modifying endothelial function during dengue virus infection remains unclear. In this study, we showed that severe dengue patients' plasma-derived EV (SD-EV) were found to carry elevated levels of different protein cargos, e.

Vaginitis is the most common problem afflicting women of childbearing age. However, the underlying etiological factors remain poorly understood, leading to recurrent vaginitis and constraining clinical management. Here, we explored whether the gut microbiota influences the risk of vaginitis by performing a two-sample Mendelian randomization analysis using the largest genome-wide association studies to date.
