Urinary Neutrophil Gelatinase-associated Lipocalin as a Marker for Identification of Acute Kidney Injury and Recovery in Dogs with Gentamicin-induced Nephrotoxicity.

Background: Acute kidney injury (AKI) is associated with high mortality rates in dogs, which may be a consequence of late recognition using traditional diagnostic tests. Neutrophil gelatinase-associated lipocalin (NGAL) is a protein-induced during kidney injury that may identify AKI earlier than traditional tests.

Objectives/hypothesis: To evaluate urinary NGAL (uNGAL) and uNGAL-to-urinary creatinine ratio (UNCR) as early markers of kidney injury and recovery in an AKI model in dogs.

Disease Expression in Autosomal Recessive Retinal Dystrophy Associated With Mutations in the DRAM2 Gene.

Purpose: To determine the disease course of retinal dystrophy caused by recessive variants in the DRAM2 (damage-regulated autophagy modulator 2) gene.

Methods: Sixteen individuals with DRAM2-retinopathy were examined (six families; age range, 19-56 years, includes one pre-symptomatic case). The change in visual acuity over time was studied, and electrophysiology (n = 6), retina-tracking perimetry (n = 1), fundus autofluorescence (FAF) imaging (n = 6), and optical coherence tomography (OCT; n = 12) were performed.

Methodological assessment of 2b-RAD genotyping technique for population structure inferences in yellowfin tuna (Thunnus albacares).

Global population genetic structure of yellowfin tuna (Thunnus albacares) is still poorly understood despite its relevance for the tuna fishery industry. Low levels of genetic differentiation among oceans speak in favour of the existence of a single panmictic population worldwide of this highly migratory fish. However, recent studies indicated genetic structuring at a much smaller geographic scales than previously considered, pointing out that YFT population genetic structure has not been properly assessed so far.

Concurrent Validity of the International Family Quality of Life Survey.

The measurement of the social construct of Family Quality of Life (FQOL) is a parsimonious alternative to the current approach of measuring familial outcomes using a battery of tools related to individual-level outcomes. The purpose of this study was to examine the internal consistency and concurrent validity of the International FQOL Survey (FQOLS-2006), using cross-sectional data collected from 65 family caregivers of children with developmental disabilities. It shows a moderate correlation between the total FQOL scores of the FQOLS-2006 and the Beach Center's FQOL scale.

Mutations in CTNNA1 cause butterfly-shaped pigment dystrophy and perturbed retinal pigment epithelium integrity.

Butterfly-shaped pigment dystrophy is an eye disease characterized by lesions in the macula that can resemble the wings of a butterfly. Here we report the identification of heterozygous missense mutations in the CTNNA1 gene (encoding α-catenin 1) in three families with butterfly-shaped pigment dystrophy. In addition, we identified a Ctnna1 missense mutation in a chemically induced mouse mutant, tvrm5.

Purpose: To describe in detail the retinal structure and function of a group of patients with cobalamin C (cblC) disease.

Methods: Patients (n = 11, age 4 months to 15 years) with cblC disease (9/11, early onset) diagnosed by newborn screening underwent complete ophthalmic examinations, fundus photography, near-infrared reflectance imaging, and spectral-domain optical coherence tomography (SD-OCT). Electroretinograms (ERGs) were performed in a subset of patients.

A Nonsense Mutation in FAM161A Is a Recurrent Founder Allele in Dutch and Belgian Individuals With Autosomal Recessive Retinitis Pigmentosa.

Purpose: To identify mutations in FAM161A underlying autosomal recessive retinitis pigmentosa (arRP) in the Dutch and Belgian populations and to investigate whether common FAM161A-associated phenotypic features could be identified.

Methods: Homozygosity mapping, amplification-refractory mutation system (ARMS) analysis, and Sanger sequencing were performed to identify mutations in FAM161A. Microsatellite and SNP markers were genotyped for haplotype analysis.

From Novice to Seasoned Practitioner: a Qualitative Investigation of Genetic Counselor Professional Development.

Research on genetic counselor professional development would characterize typical developmental processes, inform training and supervision, and promote life-long development opportunities. To date, however no studies have comprehensively examined this phenomenon. The aims of this study were to investigate the nature of professional development for genetic counselors (processes, influences, and outcomes) and whether professional development varies across experience levels.

Previous radiation for prostate neoplasm alters surgical and oncologic outcomes after rectal cancer surgery.

Background: Previous radiation for prostate cancer (PC) contra-indicates neoadjuvant chemoradiotherapy for rectal cancer (RC) because of risk of cumulative radiation dose toxicity. Postoperative outcomes after proctectomy have not been well studied in these patients who did not receive optimal treatment.

Methods: Eighty-four consecutive male patients underwent surgery for stage II-III mid or low RC between 2002 and 2011.

Development, Experience, and Expression of Meaning in Genetic Counselors' Lives: an Exploratory Analysis.

Genetic counselors routinely engage with patients and families who grapple with questions of meaning while making decisions about genetic risk. Research and theory demonstrate genetic counselors gain important personal insights through their work and develop professionally from self-reflective practice regarding their beliefs and values. Data are lacking, however, about the nature of the meaning genetic counselors bring to their profession and how they directly experience and/or navigate issues of meaning within clinical practice over time.

Colour Vision in Stargardt Disease.

Purpose: To investigate the type and severity of acquired colour vision deficiencies (CVDs) in molecularly proven Stargardt disease (STD) and to establish whether a relationship exists between best-corrected visual acuity (BCVA) and full-field electroretinography (ffERG), and the degree of CVD.

Methods: A retrospective, cross-sectional study of 73 patients with a molecularly proven diagnosis of STD, who underwent extensive colour vision evaluation, using pseudo-isochromatic and arrangement tests. Thirteen patients underwent Nagel anomaloscopy.

Objective classification of latent behavioral states in bio-logging data using multivariate-normal hidden Markov models.

Analysis of complex time-series data from ecological system study requires quantitative tools for objective description and classification. These tools must take into account largely ignored problems of bias in manual classification, autocorrelation, and noise. Here we describe a method using existing estimation techniques for multivariate-normal hidden Markov models (HMMs) to develop such a classification.

Returning a Research Participant's Genomic Results to Relatives: Analysis and Recommendations.

Genomic research results and incidental findings with health implications for a research participant are of potential interest not only to the participant, but also to the participant's family. Yet investigators lack guidance on return of results to relatives, including after the participant's death. In this paper, a national working group offers consensus analysis and recommendations, including an ethical framework to guide investigators in managing this challenging issue, before and after the participant's death.

Public interest in personal whole genome sequencing is increasing. The technology is publicly available and is being used as an educational tool in higher education. Empirical evidence regarding its utility is vital.

Defining Our Clinical Practice: The Identification of Genetic Counseling Outcomes Utilizing the Reciprocal Engagement Model.

The need for evidence-based medicine, including comparative effectiveness studies and patient-centered outcomes research, has become a major healthcare focus. To date, a comprehensive list of genetic counseling outcomes, as espoused by genetic counselors, has not been established and thus, identification of outcomes unique to genetic counseling services has become a priority for the National Society of Genetic Counselors (NSGC). The purpose of this study was to take a critical first step at identifying a more comprehensive list of genetic counseling outcomes.

An integrated transcriptomic and proteomic analysis of sea star epidermal secretions identifies proteins involved in defense and adhesion.

Sea stars rely on epidermal secretions to cope with their benthic life. Their integument produces a mucus, which represents the first barrier against invaders; and their tube feet produce adhesive secretions to pry open mussels and attach strongly but temporarily to rocks. In this study, we combined high-throughput sequencing of expressed mRNA and mass-spectrometry-based identification of proteins to establish the first proteome of mucous and adhesive secretions from the sea star Asterias rubens.

Evaluation of miR-122 as a Serum Biomarker for Hepatotoxicity in Investigative Rat Toxicology Studies.

MicroRNAs are short noncoding RNAs involved in regulation of gene expression. Certain microRNAs, including miR-122, seem to have ideal properties as biomarkers due to good stability, high tissue specificity, and ease of detection across multiple species. Recent reports have indicated that miR-122 is a highly liver-specific marker detectable in serum after liver injury.

Report on an Investigation into an Entry Level Clinical Doctorate for the Genetic Counseling Profession and a Survey of the Association of Genetic Counseling Program Directors.

The master's degree is the required entry-level degree for the genetic counseling profession in the US and Canada. In 2012 the Association of Genetic Counseling Program Directors (AGCPD) passed resolutions supporting retention of the master's as the entry-level and terminal degree and opposing introduction of an entry-level clinical doctorate (CD) degree. An AGCPD workgroup surveyed directors of all 34 accredited training programs with the objective of providing the Genetic Counseling Advanced Degrees Task Force (GCADTF) with information regarding potential challenges if master's programs were required to transition to an entry-level CD.

Biallelic mutations in the autophagy regulator DRAM2 cause retinal dystrophy with early macular involvement.

Retinal dystrophies are an overlapping group of genetically heterogeneous conditions resulting from mutations in more than 250 genes. Here we describe five families affected by an adult-onset retinal dystrophy with early macular involvement and associated central visual loss in the third or fourth decade of life. Affected individuals were found to harbor disease-causing variants in DRAM2 (DNA-damage regulated autophagy modulator protein 2).
