Background: Transition from pediatric to adult healthcare and services is an important event in the life course of all youth, including youth living with medical complexity. Data from the National Survey of Children's Health indicates less than 20 % of youth receive health care transition services. The goal of our study was understanding the support, tools and resources that facilitate successful health care transition of young adults living with medical complexity.

Introduction: The benefit of adding an immunomodulator to vedolizumab and ustekinumab remains unclear and may compromise the safety of these biologics. We evaluated the prevalence and predictors of immunomodulator use with vedolizumab or ustekinumab in patients with inflammatory bowel disease in a large longitudinal cohort.

Methods: Clinical information was ascertained from electronic medical records of patients enrolled in TARGET-IBD, a prospective longitudinal observational cohort of patients with inflammatory bowel disease (IBD) at 34 sites.

Patients with inflammatory bowel disease (IBD) are not at increased risk of SARS-CoV-2 infection compared to the general population, and most are not at increased risk for severe disease. COVID-19 is nonetheless common, and vaccination is critical. Four safe and efficacious vaccines are now available for the prevention of COVID-19, with most data available for mRNA vaccines.

Background: Some patients with inflammatory bowel disease (IBD) on immunosuppressive therapies may have a blunted response to certain vaccines, including the messenger RNA (mRNA) coronavirus disease 2019 (COVID-19) vaccines. However, few studies have evaluated the cell-mediated immune response (CMIR), which is critical to host defense after COVID-19 infection. The aim of this study was to evaluate the humoral immune response and CMIR after mRNA COVID-19 vaccination in patients with IBD.

Introduction: Patients with inflammatory bowel disease (IBD) on immune-modifying therapies may have a lower vaccine response to certain vaccines. The aim of our study was to evaluate humoral immunogenicity of mRNA coronavirus disease 2019 (COVID-19) vaccines among patients with IBD and healthy controls (HCs).

Methods: We performed a prospective study to evaluate humoral immunogenicity among patients with IBD and HCs after completion of mRNA COVID-19 vaccines.

Prior small reports have postulated a link between gastrointestinal polyposis and childhood and young adulthood cancer (CYAC) treatment (therapy-associated polyposis; TAP), but this remains a poorly understood phenomenon. The aim of this study was to describe the phenotypic spectrum of TAP in a multi-institutional cohort. TAP cases were identified from eight high-risk cancer centers.

Background And Goal: The incidence of nonalcoholic fatty liver disease (NAFLD)-associated hepatocellular carcinoma (HCC) is rising. We aimed to characterize risk factors for NAFLD-HCC development.

Methods: We performed a retrospective case-control study of HCC cases from a cohort of NAFLD patients who underwent at least 2 computed tomography scans.

Introduction: Extracellular ATP (eATP) is released by articular chondrocytes under physiological and pathological conditions. High eATP levels cause pathologic calcification, damage cartilage, and mediate pain. We recently showed that stable over-expression of the progressive ankylosis gene product, ANK, increased chondrocyte eATP levels, but the mechanisms of this effect remained unexplored.

Objective: We propose a new staging system for stage I endometrial cancer and compare its performance to the 1988 and 2009 International Federation of Gynecology and Obstetrics (FIGO) systems.

Methods: We analyzed patients with 1988 FIGO stage I endometrial cancer from January 1993 to August 2011. Low-grade carcinoma consisted of endometrioid grade 1 to grade 2 lesions.

Background: Prostate cancer is the most frequently diagnosed malignancy in men in the United States, with even higher prevalence and death rates among black men. The authors sought to compare trends in prostate-specific antigen (PSA), age, and prostate-cancer detection among black and white men in our region during a 16-year period.

Methods: This was a retrospective study of patient archives between 1990 through 2006.

1. Application of the nitric oxide (NO) donor, sodium nitrite and the NO synthase substrate l-arginine had no effect on nerve-evoked transmitter release in the rat isolated phrenic nerve/hemidiaphragm preparation; however, when adenosine A(1) receptors were blocked with the adenosine A(1) receptor antagonist 1,3-dipropyl-8-cyclopentylxanthine (DPCPX) prior to application of sodium nitrate or l-arginine, a significant increase in transmitter release was observed. In addition, the NO donor s-nitroso-N-acetylpenicillamine (SNAP) significantly increased transmitter release in the presence of DPCPX.

Purpose: Increasing age has been associated with decreasing male sexual function. We evaluated the association of urogenital pain with sexual function in a community based cohort of older men.

Materials And Methods: In 2000, 1,764 white men with a median age of 60 years residing in Olmsted County, Minnesota completed a questionnaire that included questions from the National Institutes of Health Chronic Prostatitis Symptom Index to evaluate urogenital pain that is ejaculatory, penile, perineal, suprapubic and testicular pain, and pain on urination.
