Using a recently available WHO international standard for anti-SARS-CoV-2 antibody, we provide assay unit conversion factors to international units for each of the assays examined. We performed a longitudinal survey of healthy vaccinated individuals, finding that median AdviseDx immunoglobulin levels peaked 7 weeks after first vaccine dose at approximately 4,000 IU/ml. Intriguingly, among the five assays examined, there was no significant difference in antigen binding level or neutralizing activity between two seropositive patients protected against SARS-CoV-2 infection in a previously described fishing vessel outbreak and five health care workers who experienced vaccine breakthrough of SARS-CoV-2 infection, all with variants of concern. These findings suggest that protection against SARS-CoV-2 infection cannot currently be predicted exclusively using in vitro antibody assays against wild-type SARS-CoV-2 spike. Infigratinib Further work is required to establish protective correlates for SARS-CoV-2 infection.BACKGROUND A key therapeutic goal of metastatic renal cell carcinoma (mRCC) treatment is delayed disease progression. The degree to which early therapeutic success affects downstream outcomes is not well established. OBJECTIVE To assess the clinical and economic impact of early vs delayed disease progression in patients with mRCC treated with first-line (1L) tyrosine kinase inhibitors (TKIs) followed by second-line (2L) therapy in the US Veterans Health Administration (VHA) database. METHODS Adult patients newly diagnosed with mRCC who were treated with a TKI as 1L therapy and who progressed to 2L therapy from October 1, 2013, through March 31, 2018, were identified from the US VHA database. Patients were stratified by median time from initiation of 1L therapy to initiation of 2L therapy into early (median time or sooner)and delayed (longer than the median) progression cohorts. Clinical outcomes (time to 2L therapy discontinuation, time to third-line [3L] treatment initiation, and overall survival) were assesarch 2020 conference, May 18-20, 2020; the virtual American Society of Clinical Oncology Annual Meeting, May 29-31, 2020; and AMCP Nexus 2020 Virtual, October 20-23, 2020.BACKGROUND Data on the clinical and economic burden of eosinophilic granulomatosis with polyangiitis (EGPA) are limited. OBJECTIVE To assess the real-world clinical and economic outcomes of patients diagnosed with EGPA vs patients with asthma (present in > 90% of EGPA cases) receiving treatment in the United States. METHODS This retrospective cohort study (HO-17-17742) used administrative claims data (July 1, 2007-May 31, 2017) from the Optum Research Database. Eligible patients were aged at least 18 years at index (first date that patients met the EGPA or asthma cohort definition), with a minimum of 6 months of continuous health plan coverage before the index (baseline) period and 12 months following and including the index date (follow-up period). Patients with EGPA were identified either via published algorithms using claim code combinations for conditions and medications (before October 1, 2015) or via a claim with the EGPA ICD-10-CM code (M30.1, after October 1, 2015). Patients with asthma were identifiets with EGPA experienced disease relapses over 12 months. These results highlight the high disease burden in patients with EGPA and the need for improved treatment options. DISCLOSURES This study was funded by GlaxoSmithKline (GSK ID HO-17-17742). Bell is an employee of GSK and holds stock/share options in GSK. Blauer-Peterson is an employee of Optum, which was funded by GSK to conduct the study. Mao was an employee of Optum at the time the study was conducted. The authors report no other potential conflicts of interest. These data have previously been presented as a poster at the American College of Rheumatology/Association of Rheumatology Health Professionals Annual Meeting, Chicago, IL, October 19-24, 2018.A 207-amino acid residue endoglucanohydrolase (EG1) belonging to the glycoside hydrolase 45 (GH45) from Rhizoctonia solani acts as a pathogen associated molecular pattern (PAMP). However, the mechanism of EG1 inducing plant immunity is unclear. Here, we found that EG1 contains two domains related to its PAMP function. Transient expression showed mutation deleting 60 amino acid residuesfrom the N-terminal; EG1-1, still reserved the PAMP function. Further truncation of EG1-1 obtained two truncating mutations, EG1-2 deleting seven amino acid residues from the N-terminal of EG1-1 (SPWAVND) and EG1-3 deleting five amino acid residues from the C-terminal of EG1-1 (GCSRK). Transient expression showed that the two truncating mutations EG1-2 and EG1-3 all lost the PAMP function. Site-directed mutagenesis of EG1-1 showed that the three amino acid residues (P, W, and D) in the region SPWAVND and the two amino acid residues (C and R) in the region GCSRK were involved in the PAMP function. The homology model showed that the two regions were located at a surface on the EG1 and structurally independent. These results demonstrate that there are two functional regions for the plant immune function of the EG1 released by Rhizoctonia solani, and the two functional regions are independent of each other.

colorectal cancer (CRC) has an important impact on morbidity and mortality globally, and nitroxidative stress, inflammation, and nutritional status are linked with its progression.

to analyze the association of inflammatory, anthropometric, functional, and oxidative markers with tumor stage in newly-diagnosed CRC patients at a public reference center in Maceió, Alagoas, Brazil.

patient-generated subjective global assessment was applied, and weight, height, arm circumference, triceps skinfold (TSF), arm muscle circumference, and handgrip strength were obtained. A fasting blood sample was collected, centrifuged, and the serum was stored at -80 °C until the analysis. Malonaldehyde levels were quantified by HPLC (high-performance liquid chromatography) and cytokines, namely tumor necrosis factor-alpha, and interleukins IL-6, IL-8, and IL-17 were analyzed by ELISA. Patients were grouped according to cancer stage into group 1 (stage 0-III) and group 2 (stage IV). A binary logistic regression analysis was performed, adjusted for sex and age, to assess the relationships between the variables studied and cancer stage.
