Breast health education for working women in Appalachia: insights from focus group research.
(25/161)
BACKGROUND: This study seeks to understand rural working women, their knowledge of health systems, and how breast health issues fit into their lives. A key aim of this study was to identify regionally and culturally specific factors that influence how these women approach breast health and to identify ways that more positive breast health behaviors can be achieved. METHODS: Five focus groups (N = 42) were conducted among women at sites where the Breast Health Outreach Program (BHOP) had been conducted. Focus groups were composed of 7 to 10 women who were in about the same age cohort. RESULTS: Women provided multiple insights about their attitudes and behaviors related to breast heath concerns. Analysis of the data revealed that many of the comments clustered around two types of "systems" in these women's lives: the professional health care system and personal community systems. The BHOP provides a bridge between these two systems and seems to facilitate positive actions. Workplace health professionals also provide a bridge between professional and personal systems. CONCLUSIONS: Women exhibited the general distrust of the medical system that the literature indicates is often associated with Appalachian culture. However, this study found that distrust can be overcome with education programs that meet women where they live and work. Such programs are most likely to be successful when the materials and methods are sensitive to Appalachian culture and when medical services are brought into the community. (+info)
The importance of comparative phylogeography in diagnosing introduced species: a lesson from the seal salamander, Desmognathus monticola.
(26/161)
BACKGROUND: In most regions of the world human influences on the distribution of flora and fauna predate complete biotic surveys. In some cases this challenges our ability to discriminate native from introduced species. This distinction is particularly critical for isolated populations, because relicts of native species may need to be conserved, whereas introduced species may require immediate eradication. Recently an isolated population of seal salamanders, Desmognathus monticola, was discovered on the Ozark Plateau, approximately 700 km west of its broad continuous distribution in the Appalachian Mountains of eastern North America. Using Nested Clade Analysis (NCA) we test whether the Ozark isolate results from population fragmentation (a natural relict) or long distance dispersal (a human-mediated introduction). RESULTS: Despite its broad distribution in the Appalachian Mountains, the primary haplotype diversity of D. monticola is restricted to less than 2.5% of the distribution in the extreme southern Appalachians, where genetic diversity is high for other co-distributed species. By intensively sampling this genetically diverse region we located haplotypes identical to the Ozark isolate. Nested Clade Analysis supports the hypothesis that the Ozark population was introduced, but it was necessary to include haplotypes that are less than or equal to 0.733% divergent from the Ozark population in order to arrive at this conclusion. These critical haplotypes only occur in < 1.2% of the native distribution and NCA excluding them suggest that the Ozark population is a natural relict. CONCLUSION: Our analyses suggest that the isolated population of D. monticola from the Ozarks is not native to the region and may need to be extirpated rather than conserved, particularly because of its potential negative impacts on endemic Ozark stream salamander communities. Diagnosing a species as introduced may require locating nearly identical haplotypes in the known native distribution, which may be a major undertaking. Our study demonstrates the importance of considering comparative phylogeographic information for locating critical haplotypes when distinguishing native from introduced species. (+info)
Cercophora rubrotuberculata sp. nov., a new pyrenomycete from the Great Smoky Mountains National Park.
(27/161)
An interesting wood-inhabiting pyrenomycete was discovered while collecting for the All Taxa Biodiversity Inventory currently being conducted in the Great Smoky Mountains National Park. This species is unique in possessing superficial ascomata with reddish tubercles and ascospores that develop an apical swollen brown cell and a long, basal hyaline cell. Because these ascospore characters fit the traditional morphological circumscription of Cercophora, this species is described as a new species within this genus. (+info)
Cancer in Appalachia, 2001-2003.
(28/161)
BACKGROUND: Researchers have not been able to examine cancer incidence rates in Appalachia because high-quality data have not been uniformly available across the region. This study is the first to report cancer incidence rates for a large proportion of the Appalachian population and describe the differences in incidence rates between Northern, Central, and Southern Appalachia. METHODS: Forty-four states and the District of Columbia provided information for the diagnosis years 2001 through 2003 from cancer registries that met high-quality data criteria. Eleven of 13 states with counties in Appalachia, covering 88% of the Appalachian population, met these criteria; Virginia and Mississippi were included for 2003 only. SEER(*)Stat was used to calculate age-adjusted rates per 100,000 population and 95% gamma confidence limits. RESULTS: Overall, cancer incidence rates were higher in Appalachia than in the rest of the US; the rates for lung, colon/rectum, and other tobacco-related cancers were particularly high. Central Appalachia had the highest rates of lung (men: 143.8; women: 75.2) and cervical cancer (11.2)-higher than the other 2 regions and the rest of the US. Northern Appalachia had the highest rates for prostate, female breast, and selected other sites, and Southern Appalachia had the lowest overall cancer incidence rates. CONCLUSIONS: Cancer incidence rates in Appalachia are higher than in the rest of the US, and they vary substantially between regions. Additional studies are needed to understand how these variations within Appalachia are associated with lifestyle, socioeconomic factors, urban/rural residence, and access to care. (+info)
