Trends in Accuracy and Comprehensiveness of Pathology Reports for Resected NSCLC in a High Mortality Area of the United States.

Introduction: Complete and accurate pathology reports are vital to postoperative prognostication and management. We evaluated the impact of three interventions across a diverse group of hospitals on pathology reports of postresection NSCLC.

Methods: We evaluated pathology reports for patients who underwent curative-intent surgical resection for NSCLC, at 11 institutions within four contiguous Dartmouth Hospital Referral Regions in Arkansas, Mississippi, and Tennessee from 2004 to 2020, for completeness and accuracy, before and after the following three quality improvement interventions: education (feedback to heighten awareness); synoptic reporting; and a lymph node specimen collection kit.

Improving the pathologic evaluation of lung cancer resection specimens.

Accurate post-operative prognostication and management heavily depend on pathologic nodal stage. Patients with nodal metastasis benefit from post-operative adjuvant chemotherapy, those with mediastinal nodal involvement may also benefit from adjuvant radiation therapy. However, the quality of pathologic nodal staging varies significantly, with major survival implications in large populations of patients.

Bacterial adherence. Adhesin receptor-mediated attachment of pathogenic bacteria to mucosal surfaces.

Pathogenic bacteria adhere to and colonize mucosal surfaces of the susceptible host in a highly selective manner. After the organisms penetrate the nonspecific mechanical and cleansing forces, ligands (or adhesins) on the surface of the bacteria interact in a lock-and-key fashion with complementary receptors on mucosal surfaces of the host. The adhesins are usually composed of proteins in the form of fimbriae or fibrillae and the receptors of glycolipids or glycoproteins.

Isolation and characterization of a receptor for type 1 fimbriae of Escherichia coli from guinea pig erythrocytes.

The adhesion of Escherichia coli to eukaryotic cells is mediated by proteinaceous surface appendages called fimbriae and complementary receptors on host cells. Although type 1 fimbriae, which contain a D-mannose-reactive lectin, have been well studied little is known about the binding mechanism of isolated fimbriae to individual cell receptors. This report describes the isolation and purification of a guinea pig erythrocyte receptor for type 1 fimbriae.

Protection against Escherichia coli-induced urinary tract infections with hybridoma antibodies directed against type 1 fimbriae or complementary D-mannose receptors.

Hybridoma antibodies directed against quaternary structural epitopes of the type 1 fimbrial adhesin of Escherichia coli or against D-mannose, the sugar determinant in the complementary host cell receptor, prevented the attachment of mannose-sensitive E. coli to various eucaryotic cells. Passive intraperitoneal administration of the fimbria-specific or D-mannose-specific antibodies protected mice against retrograde colonization with mannose-sensitive E.
