Effects of Changes in the Levels of Damage-Associated Molecular Patterns Following Continuous Veno–Venous Hemofiltration Therapy on Outcomes in Acute Kidney Injury Patients With Sepsis

Jie Wu, Jianan Ren, Qinjie Liu et al. · 2019 · Frontiers in Immunology

Background: Continuous veno–venous hemofiltration (CVVH) could influence immunomodulation by cytokine removal. Damage-associated molecular patterns (DAMPs) are released by injured cells and have roles in sepsis. We investigated if the magnitude of DAMPs removal was associated with mortality in patients with sepsis undergoing CVVH. Methods: We conducted a prospective, observational study on patients acquiring CVVH at department of surgery, Jinling Hospital. Circulating levels of DAMPs (mitochondrial DNA [mtDNA]; nuclear DNA [nDNA]; heat shock protein [HSP]70) and cytokines were measured at the

Effect of the change in antiviral therapy indication on identifying significant liver injury among chronic hepatitis B virus infections in the grey zone

Shan Ren, Wenjing Wang, Junfeng Lu et al. · 2022 · Frontiers in Immunology

Objective In clinical practice, a substantial proportion of chronic hepatitis B virus (HBV) infections that do not fit into any of the usual immune states are considered to be in the “grey zone (GZ)”. This study aimed to investigate the…

Impact of the Glucagon Assay When Assessing the Effect of Chronic Liraglutide Therapy on Glucagon Secretion

Caroline K. Kramer, Bernard Zinman, Haysook Choi et al. · 2017 · The Journal of Clinical Endocrinology & Metabolism

Context: Glucagon-like peptide-1 agonists acutely lower serum glucagon. However, in the Liraglutide and β-Cell Repair (LIBRA) Trial, 48-week treatment with liraglutide yielded lower/unchanged fasting glucagon but, surprisingly, enhanced…

The Meta-Science of Adult Statistical Word Segmentation: Part 1

Joshua K. Hartshorne, Lauren Skorb, Sven L. Dietz et al. · 2019 · Collabra Psychology

We report the first set of results in a multi-year project to assess the robustness – and the factors promoting robustness – of the adult statistical word segmentation literature. This includes eight total experiments replicating six different experiments. The purpose of these replications is to assess the reproducibility of reported experiments, examine the replicability of their results, and provide more accurate effect size estimates. Reproducibility was mixed, with several papers either lacking crucial details or containing errors in the description of method, making it difficult to ascert
