Establishing the Omics Nursing Science & Education Network.

PURPOSE: To establish a website to advance nursing research and education involving omics technologies and methodologies through facilitating collaborations, use of existing data and samples, mentoring, and access to training opportunities. METHODS: The Omics Nursing Science & Education Network (ONSEN) website was established following identification of gaps in omics nursing infrastructure and resources that could be addressed via a concerted, collaborative effort. ONSEN content was created using input from a workgroup of experts in genomics and other omics, education, practice, and nursing research. Alpha testing was conducted with workgroup members, followed by website refinements and enhancements, and subsequent beta testing by potential end users. ONSEN was launched in August 2018. FINDINGS: ONSEN has three main sections. The Education and Training section provides information on mentoring and pre- or postdoctoral opportunities in addition to a knowledge matrix to advance education and skills in genomic nursing science. The Research Collaborations section promotes awareness of ongoing omics nursing research in order to foster collaborations and sharing of samples or data among investigators with programs in omics nursing research or an interest in developing such programs. The Common Data Elements (CDE) section provides information on the benefits of incorporating CDEs into nursing science as well as links to National Institutes of Health resources to facilitate use of CDEs. CONCLUSIONS: ONSEN provides opportunities for nurse scientists and trainees to leverage samples and datasets, locate mentors and pre- or postdoctoral positions, further the use of CDEs, and enhance education and skills for integrating omics into nursing science. CLINICAL RELEVANCE: Advancing omics nursing science via ONSEN resources will accelerate the elucidation of the molecular underpinnings of disease and associated symptoms as well as inform the development of rapidly translatable, personalized intervention strategies, grounded in biological mechanisms, for improved health outcomes across populations and the lifespan.

A blueprint for genomic nursing science.

PURPOSE: This article reports on recommendations arising from an invitational workshop series held at the National Institutes of Health for the purposes of identifying critical genomics problems important to the health of the public that can be addressed through nursing science. The overall purpose of the Genomic Nursing State of the Science Initiative is to establish a nursing research blueprint based on gaps in the evidence and expert evaluation of the current state of the science and through public comment. ORGANIZING CONSTRUCTS: A Genomic Nursing State of the Science Advisory Panel was convened in 2012 to develop the nursing research blueprint. The Advisory Panel, which met via two webinars and two in-person meetings, considered existing evidence from evidence reviews, testimony from key stakeholder groups, presentations from experts in research synthesis, and public comment. FINDINGS: The genomic nursing science blueprint arising from the Genomic Nursing State of Science Advisory Panel focuses on biologic plausibility studies as well as interventions likely to improve a variety of outcomes (e.g., clinical, economic, environmental). It also includes all care settings and diverse populations. The focus is on (a) the client, defined as person, family, community, or population; (b) the context, targeting informatics support systems, capacity building, education, and environmental influences; and (c) cross-cutting themes. It was agreed that building capacity to measure the impact of nursing actions on costs, quality, and outcomes of patient care is a strategic and scientific priority if findings are to be synthesized and aggregated to inform practice and policy. CONCLUSIONS: The genomic nursing science blueprint provides the framework for furthering genomic nursing science to improve health outcomes. This blueprint is an independent recommendation of the Advisory Panel with input from the public and is not a policy statement of the National Institutes of Health or the federal government. CLINICAL RELEVANCE: This genomic nursing science blueprint targets research to build the evidence base to inform integration of genomics into nursing practice and regulation (such as nursing licensure requirements, institutional accreditation, and academic nursing school accreditation).

National Institutes of Health Research Plan on Rehabilitation: NIH Medical Rehabilitation Coordinating Committee.

One in five Americans experiences disability that affects their daily function because of impairments in mobility, cognitive function, sensory impairment, or communication impairment. The need for rehabilitation strategies to optimize function and reduce disability is a clear priority for research to address this public health challenge. The National Institutes of Health (NIH) recently published a Research Plan on Rehabilitation that provides a set of priorities to guide the field over the next 5 years. The plan was developed with input from multiple Institutes and Centers within the NIH, the National Advisory Board for Medical Rehabilitation Research, and the public. This article provides an overview of the need for this research plan, an outline of its development, and a listing of six priority areas for research. The NIH is committed to working with all stakeholder communities engaged in rehabilitation research to track progress made on these priorities and to work to advance the science of medical rehabilitation.This article is being published almost simultaneously in the following six journals: American Journal of Occupational Therapy, American Journal of Physical Medicine and Rehabilitation, Archives of Physical Medicine and Rehabilitation, Neurorehabilitation and Neural Repair, Physical Therapy, and Rehabilitation Psychology.

The common deletion found in patient reexamined after 33 years and comparison with complete mtDNA sequences of maternal relatives.

In 1966, a male (17 years old) was clinically examined at the National Institutes of Health (NIH) and diagnosed with Idiopathic Progressive External Ophthalmoplegia (IPEO). A muscle biopsy showing ragged-red fibers implicated mitochondrial involvement. Since the sequence of human mitochondrial DNA (mtDNA) was not determined until 1981, no genetic confirmation of the disease was possible at that time. In 1999, clinical reexamination and sequencing the entire mtDNA of the patient and living maternal relatives (mother and brother) indicated a progressive mitochondrial myopathy and the presence of the 4977 base pair (bp) deletion (the common deletion) in the patient.

Renewable standard reference material for the detection of TP53 mutations.

BACKGROUND: Numerous DNA-based tests are currently in use or under development for the detection of mutations associated with disease. Most of the current methods use PCR amplification technologies and detection after separation or chromatography of the products. We have developed a panel of standard reference materials consisting of 12 plasmid clones containing a 2.0 kb region of the TP53 gene, including exons 5-9. Eleven of these clones contain a single mutation within the mutational hot spots of the TP53 gene, the twelfth is wild-type in this region of the gene. The mutations are amino acid (aa) 128: C to T; aa 175: G to A; aa 237: T to C; aa 245: G to A; aa 248: C to T; aa 248: G to A; aa 249: G to T; aa 273: C to T; aa 273: G to A; aa 282: C to T; and aa 328: T to C. These standard reference materials (SRMs), created by site-directed mutagenesis of wild-type TP53 from a human cell line, include the specific mutations most commonly found to be associated with cancer. Their use will improve disease detection by serving as validation materials to monitor errors in measurement methods, including PCR amplification, amplicon separation, and data analysis from different technology platforms. METHODS AND RESULTS: The single point mutations of the panel were validated by capillary electrophoresis single-strand conformational polymorphism analysis, denaturing gradient gel electrophoresis, and denaturing high-performance liquid chromatography, as well as full sequence analysis of both DNA strands of the cloned material. For both heteroduplex analysis methods, the presence of the mutations was resolved for each SRM. CONCLUSION: The generation of a standard TP53 reference panel and demonstration that the panel can successfully validate mutation detection across different mutation scanning technology platforms. Hence, this panel functions as an SRM to normalize results obtained from different laboratories using different techniques.

Characterization of surface organic components of human hair by on-line supercritical fluid extraction-gas chromatography/mass spectrometry: a feasibility study and comparison with human identification using mitochondrial DNA sequences.

This paper discusses results of a supercritical fluid extraction-gas chromatography/mass spectrometry (SFE-GC/MS) study of small samples ( 100 microg to 1 mg) of human scalp hair. The method offers a number of benefits including greater sensitivity than liquid extraction methods because the entire extractable mass is transferred to the analytical system, compared with only a few percent from a conventional liquid extraction/injection. The project's goals were to determine if SFE-GC/MS analyses of the surface-extractable components of an individual's hair yield consistent chemical profiles and to investigate if the profiles are sufficiently different to distinguish them from those of other individuals. In addition, the mtDNA sequences from ten of the same individuals used in the SFE-GC/MS study from four family units were determined, and, while the families were distinguishable, the maternal relations yielded identical sequences. In tandem, SFE-GC/MS and mtDNA techniques may provide valuable complementary data from forensic hair samples.

A Standard Reference Material to determine the sensitivity of techniques for detecting low-frequency mutations, SNPs, and heteroplasmies in mitochondrial DNA.

Human mitochondrial DNA (mtDNA) mutations are important for forensic identifications and mitochondrial disease diagnostics. Low-frequency mutations, heteroplasmies, or SNPs scattered throughout the DNA in the presence of a majority of mtDNA with the Cambridge Reference Sequence (CRS) are almost impossible to detect. Therefore, the National Institute of Science and Technology has developed heteroplasmic human mtDNA Standard Reference Material (SRM) 2394 to allow scientists to determine their sensitivity in detecting such differences. SRM 2394 is composed of mixtures ranging from 1/99 to 50/50 of two 285-bp PCR products from two cell lines that differ at one nucleotide position. Twelve laboratories using various mutation detection methods participated in a blind interlaboratory evaluation of a prototype of SRM 2394. Most of these procedures were unable to detect the mutation when present below 20%, an indication that, in many real-life cases, low-frequency mutations remain undetected and that more sensitive mutation detection techniques are urgently needed.
