Hepatocellular cancer (HCC) has been reported to belong to one of the highly vascularized solid tumours accompanied with angiogenesis of human umbilical vein endothelial cells (HUVECs). KDM5A, an attractive drug target, plays a critical role in diverse physiological processes. Thus, this study aims to investigate its role in angiogenesis and underlying mechanisms in HCC. Saracatinib solubility dmso ChIP-qPCR was utilized to validate enrichment of H3K4me3 and KDM5A on the promotor region of miR-433, while dual luciferase assay was carried out to confirm the targeting relationship between miR-433 and FXYD3. Scratch assay, transwell assay, Edu assay, pseudo-tube formation assay and mice with xenografted tumours were conducted to investigate the physiological function of KDM5A-miR-433-FXYD3-PI3K-AKT axis in the progression of HCC after loss- and gain-function assays. KDM5A p-p85 and p-AKT were highly expressed but miR-433 was down-regulated in HCC tissues and cell lines. Depletion of KDM5A led to reduced migrative, invasive and proliferative capacities in HCC cells, including growth and a lowered HUVEC angiogenic capacity in vitro. Furthermore, KDM5A suppressed the expression of miR-433 by demethylating H3K4me3 on its promoterregion. miR-433 negatively targeted FXYD3. Depleting miR-433 or re-expressing FXYD3 restores the reduced migrative, invasive and proliferative capacities, and lowers the HUVEC angiogenic capacity caused by silencing KDM5A. Therefore, KDM5A silencing significantly suppresses HCC tumorigenesis in vivo, accompanied with down-regulated miR-433 and up-regulated FXYD3-PI3K-AKT axis in tumour tissues. Lastly, KDM5A activates the FXYD3-PI3K-AKT axis to enhance angiogenesis in HCC by suppressing miR-433.Organ procurement organizations (OPO) test potential deceased organ donors for infectious diseases required by policy, but many also perform testing for additional infections. The current state of donor testing in the United States is unknown. We sent an IRB approved survey to all 57 U.S. OPOs using REDCap. Descriptive statistics were performed. From the 57 OPOs, we received 46 (80.7%) unique responses with all 11 United Network of Organ Sharing regions represented. Forty of 46 (87%) OPO respondents consulted an Infectious Diseases physician when needed. Eighteen of 46 (39%) tested for West Nile virus (WNV) and 17 of 18 (94%) tested year-round. Eleven of 46 (23.9%) tested for Strongyloides infection while 17 of 46 (37%) tested for Chagas disease. All OPOs performed prospective nucleic acid testing (NAT) for HIV, hepatitis B and hepatitis C on all donors. OPO testing of additional infections has increased since prior surveys but remains variable. Standardization of organ donor infectious diseases evaluation should be considered.Atypical porcine pestivirus (APPV), a highly divergent pestivirus, has a wide geographical distribution around the world. APPV is known to cause type A-II congenital tremors in newborn piglets. The main objective of this study is to access APPV prevalence in the US swine herds utilizing a newly developed quantitative real-time RT-PCR assay. Retrospective analysis of 1,785 samples revealed a 19.0% prevalence in Midwest swine herds over a period of three years (2016-2018). Among all clinical and field samples that were APPV positive, 82 samples (24.19%) were also positive for one or more swine viral pathogens. Two APPV US strains identified in this study demonstrated significant sequence diversity (~12% in full genome) compared to the first reported APPV strain from the United States in 2014. Of the two strains identified in this study, USA/023005/2016 is closer to two strains identified in Germany, and USA/047310/2017 shares more similarities with two US strains including Minnesota-1 and ISDVDL2014016573. Partial NS5B sequences (9127-9836 nt of the polyprotein gene) obtained from 54 APPV-positive samples revealed considerable sequence diversity, ranging from 85.8% to 100% nucleotide identity, within the US strains in samples from different geographic regions. Analysis of all US samples indicates high prevalence of APPV in Minnesota (37.35%), followed by Illinois (32.86%), Iowa (30.60%) and Kansas (21.89%). APPV was detected in 15.48% of samples assayed from 2017, slightly higher than that in 2016 (13.08%), but much lower than 2018 (28.77%). Among the various sample types tested, oral fluid samples had the highest prevalence and lowest average Ct value suggesting their suitability as a reliable diagnostic specimen for APPV detection. Overall, sequence variation among APPV strains and prevalence of the pathogen within the United States provides a basis for understanding the genetic diversity and molecular epidemiology of APPV in the US swine herds.Ready-to-use therapeutic foods (RUTF) used to treat children with severe acute malnutrition (SAM) are costly, and the prescribed dosage has not been optimized. The MANGO trial, implemented by Action Contre la Faim in Burkina Faso, proved the non-inferiority of a reduced RUTF dosage in community-based treatment of uncomplicated SAM. We performed a cost-minimization analysis to assess the economic impact of transitioning from the standard to the reduced RUTF dose. We used a decision-analytic model to simulate a cohort of 399 children/arm, aged 6-59 months and receiving SAM treatment. We adopted a societal perspective direct medical costs (drugs, materials and staff time), non-medical costs (caregiver expenses) and indirect costs (productivity loss) in 2017 international US dollar were included. Data were collected through interviews with 35 caregivers and 20 informants selected through deliberate sampling and the review trial financial documents. The overall treatment cost for 399 children/arm was $36,550 with the standard and $30,411 with the reduced dose, leading to $6,140 (16.8%) in cost savings ($15.43 saved/child treated). The cost/consultation was $11.6 and $9.6 in the standard and reduced arms, respectively, with RUTF accounting for 56.2% and 47.0% of the total. The savings/child treated was $11.4 in a scenario simulating the Burkinabè routine SAM treatment outside clinical trial settings. The reduced RUTF dose tested in the MANGO trial resulted in significant cost savings for SAM treatment. These results are useful for decision makers to estimate potential economic gains from an optimized SAM treatment protocol in Burkina Faso and similar contexts.
