Olsen, Howey, and Owen 1 DEVELOPMENT OF A REGIONAL GIS PORTAL WITH TRANSIT DATA Corresponding Author

ABSTRACT The New River Valley (NRV) Metropolitan Planning Organization (MPO) recently launched a project creating a regional GIS portal in support of transit planning initiatives. The purpose of the project is to improve connections between transit providers and other modes of transportation, and to assist on-going and future transportation planning efforts at the local and regional scale. The project was conducted in two phases. Phase I included meetings with stakeholders to assess regional needs and to discuss transit-planning processes, GIS technologies, and existing data sources. Several stakeholder agencies collaborated to share transit-related data, which was cataloged and edited for public consumption. Phase II made transit data available to the public. The MPO partnered with the NRV Planning District Commission (PDC) to host the transit data on a FTP site. Using ArcGIS Online, an interactive web map was created featuring route and stop layers for the four fixed-route providers in the region. The project provided an outlet for important discussions between regional transit stakeholders and led to increased communication and collaboration between agencies. A regional transit GIS portal was created to share transit data featuring links to the FTP site, web map and additional resources regarding the MPO project

Human Case of Swine Influenza A (H1N1) Triple Reassortant Virus Infection, Wisconsin

Zoonotic infections with swine influenza A viruses are reported sporadically. Triple reassortant swine influenza viruses have been isolated from pigs in the United States since 1998. We report a human case of upper respiratory illness associated with swine influenza A (H1N1) triple reassortant virus infection that occurred during 2005 following exposure to freshly killed pigs

Genetic Characterization of H3N2 Influenza Viruses Isolated from Pigs in North America, 1977–1999: Evidence for Wholly Human and Reassortant Virus Genotypes

Since 1998, H3N2 viruses have caused epizootics of respiratory disease in pigs throughout the major swine production regions of the U.S. These outbreaks are remarkable because swine influenza in North America had previously been caused almost exclusively by H1N1 viruses. We sequenced the full-length protein coding regions of all eight RNA segments from four H3N2 viruses that we isolated from pigs in the Midwestern U.S. between March 1998 and March 1999, as well as from H3N2 viruses recovered from a piglet in Canada in January 1997 and from a pig in Colorado in 1977. Phylogenetic analyses demonstrated that the 1977 Colorado and 1997 Ontario isolates are wholly human influenza viruses. However, the viruses isolated since 1998 from pigs in the Midwestern U.S. are reassortant viruses containing hemagglutinin, neuraminidase and PB1 polymerase genes from human influenza viruses, matrix, non-structural and nucleoprotein genes from classical swine viruses, and PA and PB2 polymerase genes from avian viruses. The HA proteins of the Midwestern reassortant swine viruses can be differentiated from those of the 1995 lineage of human H3 viruses by 12 amino acid mutations in HA1. In contrast, the Sw:ONT:97 virus, which did not spread from pig-to-pig, lacks 11 of these changes

Histologic and phenotypic factors and MC1R status associated with BRAF(V600E), BRAF(V600K), and NRAS mutations in a community-based sample of 414 cutaneous melanomas

Cutaneous melanomas arise through causal pathways involving interplay between exposure to UV radiation and host factors, resulting in characteristic patterns of driver mutations in BRAF, NRAS, and other genes. To gain clearer insights into the factors contributing to somatic mutation genotypes in melanoma, we collected clinical and epidemiologic data, performed skin examinations, and collected saliva and tumor samples from a community-based series of 414 patients aged 18 to 79, newly diagnosed with cutaneous melanoma. We assessed constitutional DNA for nine common polymorphisms in melanocortin-1 receptor gene (MC1R). Tumor DNA was assessed for somatic mutations in 25 different genes. We observed mutually exclusive mutations in BRAF (26%), BRAF (8%), BRAF (5%), and NRAS (9%). Compared to patients with BRAF wild-type melanomas, those with BRAF mutants were significantly younger, had more nevi but fewer actinic keratoses, were more likely to report a family history of melanoma, and had tumors that were more likely to harbor neval remnants. BRAF mutations were also associated with high nevus counts. Both BRAF and NRAS mutants were associated with older age but not with high sun exposure. We also found no association between MC1R status and any somatic mutations in this community sample of cutaneous melanomas, contrary to earlier reports

The physical demands of Kī-o-Rahi competition

Kī-o-Rahi is a traditional Māori ball game that encompasses the Māori world view (Palmer et al., 2009). Recently, the game has experienced a revival with ~50,000 players nationwide, including secondary school students who participate in annual regional and national tournaments (Palmer et al., 2009; Pillaar, 2011; De Graf, 2013; Brown 2010; 2013; www.kiorahi.com). To our knowledge, there are no published studies on the physical demands of Kī-o-Rahi. This information could be useful to develop specific training programmes for competition, and also to determine if Kī-o-Rahi could be used in Kaupapa Māori programmes to improve health outcomes. Therefore, the aims of our research project are: 1. To Quantify the physical demands of Kī-o-Rahi competition and 2. To determine if participation in Kī-o-Rahi meets exercise prescription guidelines for improving health. This presentation shows preliminary findings from the Canterbury secondary schools’ tournament. Informed consent was obtained, and the study had institutional ethical approval. Players (n=16; 9 females, 7 males) wore 10Hz GPS units during five of six 20min-matches in the tournament. On average, players covered 1129±256 m per match of which 484±126 m and 64±13 m were at ≥7.1 km/hr and ≥16 km/hr respectively. There was a trend for distances to decrease in later games despite the number of substitutions being similar, which suggests fatigue accumulated throughout the day. We found participation in a Kī-o-Rahi tournament was physically demanding, therefore specific training and coaching strategies may be required to ensure players are prepared for the demands of competition. Anecdotally, the game was of sufficient intensity and duration to improve fitness. However, further analysis and data collection including heart rate measurements is needed to answer the second aim of the project

Diagnostic accuracy of post-mortem MRI for thoracic abnormalities in fetuses and children

OBJECTIVES: To compare the diagnostic accuracy of post-mortem magnetic resonance imaging (PMMR) specifically for non-cardiac thoracic pathology in fetuses and children, compared with conventional autopsy. METHODS: Institutional ethics approval and parental consent was obtained. A total of 400 unselected fetuses and children underwent PMMR before conventional autopsy, reported blinded to the other dataset. RESULTS: Of 400 non-cardiac thoracic abnormalities, 113 (28 %) were found at autopsy. Overall sensitivity and specificity (95 % confidence interval) of PMMR for any thoracic pathology was poor at 39.6 % (31.0, 48.9) and 85.5 % (80.7, 89.2) respectively, with positive predictive value (PPV) 53.7 % (42.9, 64.0) and negative predictive value (NPV) 77.0 % (71.8, 81.4). Overall agreement was 71.8 % (67.1, 76.2). PMMR was most sensitive at detecting anatomical abnormalities, including pleural effusions and lung or thoracic hypoplasia, but particularly poor at detecting infection. CONCLUSIONS: PMMR currently has relatively poor diagnostic detection rates for the commonest intra-thoracic pathologies identified at autopsy in fetuses and children, including respiratory tract infection and diffuse alveolar haemorrhage. The reasonable NPV suggests that normal thoracic appearances at PMMR exclude the majority of important thoracic lesions at autopsy, and so could be useful in the context of minimally invasive autopsy for detecting non-cardiac thoracic abnormalities. KEY POINTS: • PMMR has relatively poor diagnostic detection rates for common intrathoracic pathology • The moderate NPV suggests that normal PMMR appearances exclude most important abnormalities • Lung sampling at autopsy remains the "gold standard" for pulmonary pathology

Flavonoid intakes inversely associate with COPD in smokers

Introduction: Higher flavonoid intakes are beneficially associated with pulmonary function parameters; however, their association with chronic obstructive pulmonary disease (COPD) is unknown. This study aimed to examine associations between intakes of 1) total flavonoids, 2) flavonoid subclasses and 3) major flavonoid compounds with incident COPD in participants from the Danish Diet, Cancer and Health study. Methods: This prospective cohort included 55 413 men and women without COPD, aged 50-65 years at recruitment. Habitual flavonoid intakes at baseline were estimated from a food frequency questionnaire using Phenol-Explorer. Danish nationwide registers were used to identify incident cases of COPD. Associations were modelled using restricted cubic splines within Cox proportional hazards models. Results: During 23 years of follow-up, 5557 participants were diagnosed with COPD. Of these, 4013 were current smokers, 1062 were former smokers and 482 were never-smokers. After multivariable adjustments, participants with the highest total flavonoid intakes had a 20 % lower risk of COPD than those with the lowest intakes (quintile 5 versus quintile 1: HR 0.80, 95% CI 0.74-0.87); a 6-22 % lower risk was observed for each flavonoid subclass. The inverse association between total flavonoid intake and COPD was present in both men and women but only in current smokers (HR 0.77, 95 % CI 0.70-0.84) and former smokers (HR 0.82, 95 % CI 0.69-0.97), not never-smokers. Furthermore, higher flavonoid intakes appeared to lessen, but not negate, the higher risk of COPD associated with smoking intensity. Conclusion: Dietary flavonoids may be important for partially mitigating the risk of smoking-related COPD. However, smoking cessation should remain the highest priority

Gender Dependence for a Subset of the Low-Abundance Signaling Proteome in Human Platelets

The incidence of cardiovascular diseases is ten-times higher in males than females, although the biological basis for this gender disparity is not known. However, based on the fact that antiplatelet drugs are the mainstay for prevention and therapy, we hypothesized that the signaling proteomes in platelets from normal male donors might be more activated than platelets from normal female donors. We report here that platelets from male donors express significantly higher levels of signaling cascade proteins than platelets from female donors. In silico connectivity analysis shows that the 24 major hubs in platelets from male donors focus on pathways associated with megakaryocytic expansion and platelet activation. By contrast, the 11 major hubs in platelets from female donors were found to be either negative or neutral for platelet-relevant processes. The difference may suggest a biological mechanism for gender discrimination in cardiovascular disease
