Validation of a prediction system for risk of kidney allograft failure in pediatric kidney transplant recipients: An international observational study.

Predicting long-term kidney allograft failure is an unmet need for clinical care and clinical trial optimization in children. We aimed to validate a kidney allograft failure risk prediction system in a large international cohort of pediatric kidney transplant recipients. Patients from 20 centers in Europe and the United States, transplanted between 2004 and 2017, were included.

Microstructures at the distal tip of ant chemosensory sensilla.

Ants and other eusocial insects emit and receive chemical signals to communicate important information within the colony. In ants, nestmate recognition, task allocation, and reproductive distribution of labor are largely mediated through the detection of cuticular hydrocarbons (CHCs) that cover the exoskeleton. With their large size and limited volatility, these CHCs are believed to be primarily detected through direct contact with the antennae during behavioral interactions.

Defining Information Quality Into Health Websites: A Conceptual Framework of Health Website Information Quality for Educated Young Adults.

Background: Today's health care environment encourages health care consumers to take an active role in managing their health. As digital natives, young educated adults do much of their health information management through the Internet and consider it a valid source of health advice. However, the quality of information on health websites is highly variable and dynamic.

Trauma patients warrant upper and lower extremity venous duplex ultrasound surveillance.

Background: Due to the high incidence of thromboembolic events (deep venous thrombosis [DVT] and pulmonary embolus [PE]) after injury, many trauma centers perform lower extremity surveillance duplex ultrasounds. We hypothesize that trauma patients are at a higher risk of upper extremity DVTs (UEDVTs) than lower extremity DVTs (LEDVTs), and therefore, all extremities should be evaluated.

Materials And Methods: A retrospective chart and trauma registry review of Intensive Care Unit trauma patients with upper and LEDVTs detected on surveillance duplex ultrasound from January 2010 to December 2014 was carried out.

Research START: A Multimethod Study of Barriers and Accelerators of Recruiting Research Participants.

Under-recruitment into clinical trials is a common and costly problem that undermines medical research. To better understand barriers to recruitment into clinical trials in our region, we conducted a multimethod descriptive study. We initially surveyed investigators who had conducted or were currently conducting studies that utilized an adult or pediatric clinical research center (n = 92).

Federated queries for comparative effectiveness research: performance analysis.

This paper presents a study of the performance of federated queries implemented in a system that simulates the architecture proposed for the Scalable Architecture for Federated Translational Inquiries Network (SAFTINet). Performance tests were conducted using both physical hardware and virtual machines within the test laboratory of the Center for High Performance Computing at the University of Utah. Tests were performed on SAFTINet networks ranging from 4 to 32 nodes with databases containing synthetic data for several million patients.

Gall formation in clubroot-infected Arabidopsis results from an increase in existing meristematic activities of the host but is not essential for the completion of the pathogen life cycle.

Plasmodiophora brassicae (clubroot) infection leads to reprogramming of host development resulting in the formation of characteristic galls. In this work we explored the cellular events that underly gall formation in Arabidopsis thaliana with the help of molecular markers of cell division (CYCB1:GUS) and meristematic activity (ANT:GUS). Our results show that gall development involved the amplification of existing meristematic activities within the vascular cambium (VC) and phloem parenchyma (PP) cells in the region of the hypocotyl.

Recruitment: making our efforts count.

Over the last decade, enrollments in health information technology and health information administration programs have spiraled downward resulting in the closure of programs. Reversing this trend is imperative for the survival of the health information management profession. This research study looked at: 1.

Assessment of student outcomes in undergraduate health information administration programs.

The purpose of this research was to a) determine what assessment methods are being used in undergraduate health information administration programs to assess student learning and the usefulness of those methods, b) determine to what extent programs have incorporated good student learning assessment practices. Programs use a variety of assessment tools to measure student learning; the most useful include assessments by the professional practice supervisor, course tests, assignments, presentations, capstone experiences, comprehensive projects, analyses of the students' academic progress, and the results of the RHIA credentialing examination. The greatest challenge for using the results of student outcomes assessment is making changes in a timely manner.

Ferredoxin/ferredoxin-thioredoxin reductase complex: Complete NMR mapping of the interaction site on ferredoxin by gallium substitution.

The reduction of ferredoxin-thioredoxin reductase (FTR) by plant-type ferredoxin plays an important role in redox regulation in plants and cyanobacteria. Nuclear magnetic resonance (NMR) was used to map the binding sites on Synechocystis ferredoxin for FTR. A gallium-substituted structural analog of this [2Fe-2S] ferredoxin was obtained by reconstituting the apoprotein in a refolding buffer containing gallium.
