When, where, and why should we look for vestibular dysfunction in people with diabetes mellitus?

The biochemistry of diabetes mellitus results in multi-system tissue compromise that reduces functional mobility and interferes with disease management. Sensory system compromise, such as peripheral neuropathy and retinopathy, are specific examples of tissue compromise detrimental to functional mobility. There is lack of clarity regarding if, when, and where parallel changes in the peripheral vestibular system, an additional essential sensory system for functional mobility, occur as a result of diabetes. Given the systemic nature of diabetes and the plasticity of the vestibular system, there is even less clarity regarding if potential vestibular system changes impact functional mobility in a meaningful fashion. This commentary will provide insight as to when we should employ diagnostic vestibular function tests in people with diabetes, where in the periphery we should look, and why testing may or may not matter. The commentary concludes with recommendations for future research and clinical care

Some factors influencing case classification in a public welfare agency

This group project represented an attempt to study some factors pertaining to the formation of a system of case classification in a county public welfare agency, Multnomah County Public Welfare Commission, Portland, Oregon. The classification tool was a Case Planning Schedule intended to encourage diagnostic thinking on the part of the caseworker and to enhance planning and service for the client. The focus of the study was limited to two areas: (1) whether or not the use of the Schedule resulted in agreement among caseworkers in classification and in consistency on prognoses, (2) the attitudes of the caseworkers in various departments toward the Case Classification Program and the Case Planning Schedule. Background for the study involved a search of the literature surrounding new approaches to the problems of multi-problem families and public assistance caseloads. Consideration was given to agency structure and the circumstances surrounding the creation of the Oregon Program for Case Classification. Five main hypotheses were tested. With one a comparison was made between classification and prognostication of cases with and without a case classification Schedule. The other testable hypotheses were dealt with by administration of an interviewing schedule designed to gather data regarding staff attitudes toward the Program and the Schedule. Appropriate statistical tests of significance were employed and a content analysis was used in connection with an open-ended attitudinal question. Qualitative and quantitative findings were consistent in demonstrating that caseworkers tended to be favorable toward the intent of the Program but critical toward implementation procedures. Divergent viewpoints were shown in comparing responses of workers by categories of work-load assignments departmental assignments, and length of service in the agency. These findings suggest that additional research include an evaluation of the validity of such systems

Exome-Wide Association Study of Endometrial Cancer in a Multiethnic Population

Endometrial cancer (EC) contributes substantially to total burden of cancer morbidity and mortality in the United States. Family history is a known risk factor for EC, thus genetic factors may play a role in EC pathogenesis. Three previous genome- wide association studies (GWAS) have found only one locus associated with EC, suggesting that common variants with large effects may not contribute greatly to EC risk. Alternatively, we hypothesize that rare variants may contribute to EC risk. We conducted an exome-wide association study (EXWAS) of EC using the Infinium HumanExome BeadChip in order to identify rare variants associated with EC risk. We successfully genotyped 177,139 variants in a multiethnic population of 1,055 cases and 1,778 controls from four studies that were part of the Epidemiology of Endometrial Cancer Consortium (E2C2). No variants reached global significance in the study, suggesting that more power is needed to detect modest associations between rare genetic variants and risk of EC

Retrotransposons Are the Major Contributors to the Expansion of the \u3ci\u3eDrosophila ananassae\u3c/i\u3e Muller F Element

The discordance between genome size and the complexity of eukaryotes can partly be attributed to differences in repeat density. The Muller F element (∼5.2 Mb) is the smallest chromosome in Drosophila melanogaster, but it is substantially larger (\u3e18.7 Mb) in D. ananassae. To identify the major contributors to the expansion of the F element and to assess their impact, we improved the genome sequence and annotated the genes in a 1.4-Mb region of the D. ananassae F element, and a 1.7-Mb region from the D element for comparison. We find that transposons (particularly LTR and LINE retrotransposons) are major contributors to this expansion (78.6%), while Wolbachia sequences integrated into the D. ananassae genome are minor contributors (0.02%). Both D. melanogaster and D. ananassae F-element genes exhibit distinct characteristics compared to D-element genes (e.g., larger coding spans, larger introns, more coding exons, and lower codon bias), but these differences are exaggerated in D. ananassae. Compared to D. melanogaster, the codon bias observed in D. ananassae F-element genes can primarily be attributed to mutational biases instead of selection. The 5′ ends of F-element genes in both species are enriched in dimethylation of lysine 4 on histone 3 (H3K4me2), while the coding spans are enriched in H3K9me2. Despite differences in repeat density and gene characteristics, D. ananassae F-element genes show a similar range of expression levels compared to genes in euchromatic domains. This study improves our understanding of how transposons can affect genome size and how genes can function within highly repetitive domains

How collaborative are quality improvement collaboratives:A qualitative study in stroke care

BACKGROUND: Quality improvement collaboratives (QICs) continue to be widely used, yet evidence for their effectiveness is equivocal. We sought to explain what happened in Stroke 90:10, a QIC designed to improve stroke care in 24 hospitals in the North West of England. Our study drew in part on the literature on collective action and inter-organizational collaboration. This literature has been relatively neglected in evaluations of QICs, even though they are founded on principles of co-operation and sharing. METHODS: We interviewed 32 professionals in hospitals that participated in Stroke 90:10, conducted a focus group with the QIC faculty team, and reviewed purposively sampled documents including reports and newsletters. Analysis was based on a modified form of Framework Analysis, combining sensitizing constructs derived from the literature and new, empirically derived thematic categories. RESULTS: Improvements in stroke care were attributed to QIC participation by many professionals. They described how the QIC fostered a sense of community and increased attention to stroke care within their organizations. However, participants’ experiences of the QIC varied. Starting positions were different; some organizations were achieving higher levels of performance than others before the QIC began, and some had more pre-existing experience of quality improvement methods. Some participants had more to learn, others more to teach. Some evidence of free-riding was found. Benchmarking improvement was variously experienced as friendly rivalry or as time-consuming and stressful. Participants’ competitive desire to demonstrate success sometimes conflicted with collaborative aims; some experienced competing organizational pressures or saw the QIC as duplication of effort. Experiences of inter-organizational collaboration were influenced by variations in intra-organizational support. CONCLUSIONS: Collaboration is not the only mode of behavior likely to occur within a QIC. Our study revealed a mixed picture of collaboration, free-riding and competition. QICs should learn from work on the challenges of collective action; set realistic goals; account for context; ensure sufficient time and resources are made available; and carefully manage the collaborative to mitigate the risks of collaborative inertia and unhelpful competitive or anti-cooperative behaviors. Individual organizations should assess the costs and benefits of collaboration as a means of attaining quality improvement

Genomics in the Classroom: Unraveling the Dot Chromosome of Drosophila ananassae

Drosophila Genomics is a course that offers a unique opportunity for students to contribute to a real-time research project, through support of the Genomics Education Partnership (GEP). Through instructional tutorials, students use computer programs to identify and assist in the resolution of DNA sequence inconsistencies, a process known as \u27sequence finishing\u27. The current project focuses on finishing the sequence of the unusually large 4th (dot) chromosome of D. ananassae. Once students have completed DNA sequence finishing, each student annotates a large segment of DNA from the D. biarmipes dot chromosome. In the process of annotation, students apply their understanding of gene structure to build models of genes in a specific species, using D. melanogaster as a reference species. Students gain experience accessing internet databases and use of genome analysis tools in identifying genes. Students\u27 finished work is submitted to the GEP for inclusion in future publications

Consumers' Perceptions of Patient-Accessible Electronic Medical Records

BACKGROUND: Electronic health information (eHealth) tools for patients, including patient-accessible electronic medical records (patient portals), are proliferating in health care delivery systems nationally. However, there has been very limited study of the perceived utility and functionality of portals, as well as limited assessment of these systems by vulnerable (low education level, racial/ethnic minority) consumers. OBJECTIVE: The objective of the study was to identify vulnerable consumers’ response to patient portals, their perceived utility and value, as well as their reactions to specific portal functions. METHODS: This qualitative study used 4 focus groups with 28 low education level, English-speaking consumers in June and July 2010, in New York City. RESULTS: Participants included 10 males and 18 females, ranging in age from 21-63 years; 19 non-Hispanic black, 7 Hispanic, 1 non-Hispanic White and 1 Other. None of the participants had higher than a high school level education, and 13 had less than a high school education. All participants had experience with computers and 26 used the Internet. Major themes were enhanced consumer engagement/patient empowerment, extending the doctor’s visit/enhancing communication with health care providers, literacy and health literacy factors, improved prevention and health maintenance, and privacy and security concerns. Consumers were also asked to comment on a number of key portal features. Consumers were most positive about features that increased convenience, such as making appointments and refilling prescriptions. Consumers raised concerns about a number of potential barriers to usage, such as complex language, complex visual layouts, and poor usability features. CONCLUSIONS: Most consumers were enthusiastic about patient portals and perceived that they had great utility and value. Study findings suggest that for patient portals to be effective for all consumers, portals must be designed to be easy to read, visually engaging, and have user-friendly navigation
