Identifying Colorectal Cancer Caused By Biallelic Mutyh Pathogenic Variants Using Tumor Mutational Signatures, Peter Georgeson, Yin Cao, Et Al

2020-Current year OA Pubs

Carriers of germline biallelic pathogenic variants in the MUTYH gene have a high risk of colorectal cancer. We test 5649 colorectal cancers to evaluate the discriminatory potential of a tumor mutational signature specific to MUTYH for identifying biallelic carriers and classifying variants of uncertain clinical significance (VUS). Using a tumor and matched germline targeted multi-gene panel approach, our classifier identifies all biallelic MUTYH carriers and all known non-carriers in an independent test set of 3019 colorectal cancers (accuracy = 100% (95% confidence interval 99.87-100%)). All monoallelic MUTYH carriers are classified with the non-MUTYH carriers. The classifier provides evidence for a …

Postviral Gastroparesis Associated With Sars-Cov-2 Infection In A Pediatric Patient, Courtney M. Rusch, Jerome M. Molleston, Matthew F. Glasser, Steven Don, Sakil S. Kulkarni

2020-Current year OA Pubs

Postviral gastroparesis has been described in children, but it has not yet been attributed to SARS-CoV-2 infection. Our case report describes a teenager with abdominal pain, early satiety, and vomiting who likely had an asymptomatic SARS-CoV-2 infection 2 months before presentation. Through investigation of epidemiologic links, antibody testing, and clinical course, it is hypothesized that her significant reduction in gastric emptying was due to postviral gastroparesis secondary to SARS-CoV-2. She was treated with supportive care and prokinetic agents. The patient demonstrated symptom resolution and near normalization of gastric emptying by the time of 1 month follow up.

Applying Systems Thinking To Identify Enablers And Challenges To Scale-Up Interventions For Hypertension And Diabetes In Low-Income And Middle-Income Countries: Protocol For A Longitudinal Mixed-Methods Study, Anusha Ramani-Chander, Mark D Huffman, Et Al

Open Access Publications

INTRODUCTION: There is an urgent need to reduce the burden of non-communicable diseases (NCDs), particularly in low-and middle-income countries, where the greatest burden lies. Yet, there is little research concerning the specific issues involved in scaling up NCD interventions targeting low-resource settings. We propose to examine this gap in up to 27 collaborative projects, which were funded by the Global Alliance for Chronic Diseases (GACD) 2019 Scale Up Call, reflecting a total funding investment of approximately US$50 million. These projects represent diverse countries, contexts and adopt varied approaches and study designs to scale-up complex, evidence-based interventions to improve hypertension and …

Adherence Enables Neisseria Gonorrhoeae To Overcome Zinc Limitation Imposed By Nutritional Immunity Proteins, Jocelyn C Ray, Asya Smirnov, Stavros A Maurakis, Simone A Harrison, Eugene Ke, Walter J Chazin, Cynthia Nau Cornelissen, Alison K Criss

Open Access Publications

Neisseria gonorrhoeae (Gc) must overcome the limitation of metals such as zinc to colonize mucosal surfaces in its obligate human host. While the zinc-binding nutritional immunity proteins calprotectin (S100A8/A9) and psoriasin (S100A7) are abundant in human cervicovaginal lavage fluid, Gc possesses TonB-dependent transporters TdfH and TdfJ that bind and extract zinc from the human version of these proteins, respectively. Here we investigated the contribution of zinc acquisition to Gc infection of epithelial cells of the female genital tract. We found that TdfH and TdfJ were dispensable for survival of strain FA1090 Gc that was associated with Ect1 human immortalized epithelial …
