Readability levels of individualized family service plans.

This descriptive study examined the readability levels of Individualized Family Service Plans (IFSPs). The readability of 85 de-identified IFSP documents developed by seven agencies that serve families and children enrolled in a county early intervention program was analyzed using Flesch Kincaid grade levels and Flesch reading ease scores. The average Flesch Kincaid grade level of the entire IFSP documents was 8.

SNOMED CT coding variation and grouping for "other findings" in a longitudinal study on urea cycle disorders.

Semantic interoperability requires consistent use of controlled terminologies. However, non-terminology experts (although perhaps experts in a particular domain) are prone to produce variant coding. We examine this problem by investigating SNOMED CT coding variation for other findings reported on case report forms from a clinical research study on urea cycle disorders.

A comparison of linear, fixed-form computer-based testing versus traditional paper-and-pencil-format testing in veterinary medical education.

Computerized testing has made significant inroads into veterinary education. Traditional paper-and-pencil examination formats are being replaced by computer-based testing (CBT). Computer-administered, fixed-form tests, because they mimic most closely the familiar fixed-response paper-and-pencil test formats, might intuitively seem to be inherently equivalent to their paper-and-pencil counterparts.

Evidence-based retrieval in E-health.

In this chapter we address the issue of standards for information retrieval to support decision making in e-health. Specifically, we consider the issue of evidence-based retrieval in the e-health domains of the consumer, healthcare practitioner, healthcare researcher, and genomics researcher. We present the results of a preliminary study to assess the current state of evidence-based retrieval in e-health.

Evidence-based retrieval in evidence-based medicine.

Objective: Clinical decisions based on a meta-analysis that is based on an ineffective retrieval strategy may have serious negative consequences for patients. The study objective was to investigate the extent to which meta-analyses report proof of their retrieval strategies' effectiveness.

Methods: The authors examined a random sample (n = 100) of articles in the 1996 to 2002 full-text subset of Ovid MEDLINE indexed as "meta-analysis.

A prototype system for retrieval of gene functional information.

Microarrays allow researchers to gather data about the expression patterns of thousands of genes simultaneously. Statistical analysis can reveal which genes show statistically significant results. Making biological sense of those results requires the retrieval of functional information about the genes thus identified, typically a manual gene-by-gene retrieval of information from various on-line databases.

Gene indexing: characterization and analysis of NLM's GeneRIFs.

We present an initial analysis of the National Library of Medicine's (NLM) Gene Indexing initiative. Gene Indexing occurs at the time of indexing for all 4600 journals and over 500,000 articles added to PubMed/MEDLINE each year. Gene Indexing links articles about the basic biology of a gene or protein within eight model organisms to a specific record in the NLM's LocusLink database of gene products.

Expression profiling identifies dysregulation of myosin heavy chains IIb and IIx during limb immobilization in the soleus muscles of old rats.

Aged individuals suffer from multiple dysfunctions during skeletal muscle atrophy. The purpose of this study was to determine differential changes in gene expression in atrophied soleus muscle induced by hindlimb immobilization in young (3-4 months) and old (30-31 months) rats. The hypothesis was that differentially expressed mRNAs with age-atrophy interactions would reveal candidates that induce loss of function responses in aged animals.

Selected Contribution: Identification of differentially expressed genes between young and old rat soleus muscle during recovery from immobilization-induced atrophy.

After cessation of hindlimb immobilization, which resulted in a 27-37% loss in soleus mass, the atrophied soleus muscle of young but not old rats regrows to its mass before treatment. We hypothesized that during remobilization the mRNA levels of growth potentiating factor(s) would be present in the soleus muscle of young (3- to 4-mo-old) but absent in old (30- to 31-mo-old) Fischer 344 x Brown Norway rats or that mRNAs for growth inhibitory factor(s) would be absent in young but present in old. Gene expression levels of >24,000 transcripts were determined by using Affymetrix RGU34A-C high-density oligonucleotide microarrays in soleus muscles at 3, 6, 10, and 30 days of remobilization after cessation of a 10-day period of hindlimb immobilization.

Transcriptional profiling identifies extensive downregulation of extracellular matrix gene expression in sarcopenic rat soleus muscle.

The direction of change in skeletal muscle mass differs between young and old individuals, growing in young animals and atrophying in old animals. The purpose of the experiment was to develop a statistically conservative list of genes whose expression differed significantly between young growing and old atrophying (sarcopenic) skeletal muscles, which may be contributing to physical frailty. Gene expression levels of >24,000 transcripts were determined in soleus muscle samples from young (3-4 mo) and old (30-31 mo) rats.
