Treating common stomach bacteria reduces risk of stomach cancer
Effect of Helicobacter pylori Eradication Therapy on the Incidence of Noncardia Gastric Adenocarcinoma in a Large Diverse Population in the United States
High-quality data regarding the effect of Helicobacter pylori eradication on the risk of noncardia gastric adenocarcinoma (NCGA) remain limited in the United States. We investigated the incidence of NCGA after H pylori eradication therapy in a large, community-based US population.…
Risk of Metachronous Advanced Neoplasia After Colonoscopy in Patients Aged 40-49 Years Compared to Patients Aged 50-59 Years
This study investigated the risk of metachronous advanced neoplasia (AN) after colonoscopy in individuals aged 40-49 years compared with that in individuals aged 50-59 years. A retrospective cohort study was performed among Kaiser Permanente Northern California members aged 40-59 years…
Current chemoprevention approaches in Lynch syndrome and Familial adenomatous polyposis: a global clinical practice survey
International chemoprevention preferences and approaches in Lynch syndrome (LS) and APC-associated polyposis, including Familial adenomatous polyposis (FAP) and attenuated FAP (AFAP) have not been previously explored. To describe current chemoprevention strategies for patients with LS or FAP/AFAP (referred to collectively…
Impact of the COVID-19 pandemic on fecal immunochemical testing, colonoscopy services, and colorectal neoplasia detection in a large United States community-based population
The COVID-19 pandemic has affected clinical services globally, including colorectal cancer (CRC) screening and diagnostic testing. We investigated the pandemic's impact on fecal immunochemical test (FIT) screening, colonoscopy utilization, and colorectal neoplasia detection across 21 medical centers in a large…
AGA Clinical Practice Update on the Diagnosis and Management of Atrophic Gastritis: Expert Review
The purpose of this Clinical Practice Update Expert Review is to provide clinicians with guidance on the diagnosis and management of atrophic gastritis, a common preneoplastic condition of the stomach, with a primary focus on atrophic gastritis due to chronic…
Improving health outcomes and reducing healthcare costs in individuals with Helicobacter pylori infection in a large, community-based population
Optimization of Diagnosis and Surveillance of Colonic Sessile Serrated Adenomas by Pathologists and Gastroenterologists at KPNC.
Efficacy of paired tumor and germline testing in evaluation of patients with Lynch-like syndrome in a large integrated healthcare setting
Patients with mismatch repair (MMR) deficient colorectal cancer (CRC) without detectable germline pathogenic variants (PVs) or likely pathogenic variants (LPVs) in MMR genes are often labeled as Lynch-like syndrome (LLS). We sought to evaluate the efficacy of paired tumor and…
A Transparent and Adaptable Method to Extract Colonoscopy and Pathology Data Using Natural Language Processing
Key variables recorded as text in colonoscopy and pathology reports have been extracted using natural language processing (NLP) tools that were not easily adaptable to new settings. We aimed to develop a reliable NLP tool with broad adaptability. During 1996-2016,…
Associations between Genetically Predicted Blood Protein Biomarkers and Pancreatic Cancer Risk
Pancreatic ductal adenocarcinoma (PDAC) is one of the most lethal malignancies, with few known risk factors and biomarkers. Several blood protein biomarkers have been linked to PDAC in previous studies, but these studies have assessed only a limited number of…
Comparison of Universal Versus Age-Restricted Screening of Colorectal Tumors for Lynch Syndrome Using Mismatch Repair Immunohistochemistry: A Cohort Study
Guidelines recommend screening all patients with newly diagnosed colorectal cancer (CRC) for Lynch syndrome (LS). However, the efficiency of universal LS screening in elderly populations has not been well studied. To compare the performance of age-restricted and universal LS screening…
Effect of Helicobacter pylori Treatment on Unexplained Iron Deficiency Anemia
A large number of patients with iron deficiency anemia have no known cause of their anemia despite a full evaluation. Optimal management and follow-up for this issue is unclear. Results of previous studies have implicated Helicobacter pylori infection as a…
Rates and Predictors of Vaccinations Among Inflammatory Bowel Disease Patients Receiving Anti-Tumor Necrosis Factor Agents
As an important quality measure, the rates of recommended immunizations among immunocompromised inflammatory bowel disease (IBD) patients in community practice have not been well studied. This study sought to investigate the rates and predictors of recommended immunizations and screening tests…
