A Qualitative Assessment of the International Exposition Center to the Greater Cleveland Area

This report describes the outcomes of discussions with IX Center customers and stakeholders as to how the IX Center qualitatively impacts the greater Cleveland area. The results suggest that while the IX Center is perceived to be an asset by customers and stakeholders, it’s likely that the IX Center will need to develop strategies to remain competitive with similar convention centers across the country

Nurse Practitioner Autonomy in Georgia: Exploring Barriers to Full Practice Authority

Background: There is a significant shortage of primary care physicians in Georgia, with the greatest needs in rural communities. The evidence suggests that nurse practitioners (NPs) improve the quality of care for patients with chronic diseases and may be the solution to the physician shortage. However, the scope of practice for Georgia NPs is among the most restricted in the United States. Purpose: This policy review project explored the barriers to full practice authority for nurse practitioners in the state of Georgia and assessed the impact of current policy on NPs opening independent practices in rural Georgia. The goal of the project was to build a consensus for legislative change to current NP scope of practice. Methodology: A quantitative design was used to collect data from a large nursing organization in Georgia via convenience sampling. One hundred and seventy-nine NPs responded. However, only 135 participants (N=135) consented. Participants completed an online survey in thirty minutes or less. Some questions required free text responses. One-way ANOVA and correlational analysis were used to determine differences between variables. There were no significant differences between NP characteristics (such as race, age, education level, etc) and the likelihood of opening an independent practice. Results: Most NPs (77%) reported a desire for full scope of practice, 80% believed removal of practice barriers would be an advantage to Georgia NPs, and a significant number said if autonomous practice was granted, they were likely or very likely to open an independent practice in rural Georgia

An Ecological Approach to Understanding Program Management Practices for Food Pantries in Rural Communities

This qualitative study was conducted in Mississippi, a state comprised of 82 counties, many of which are rural and highly impoverished. To gain a greater understanding of the food needs of residents from across the state, a representative sample of food pantries from each region of the state was identified. For this project, researchers with the Mississippi Food Insecurity Project formed a partnership with the Mississippi Food Network to interview partner pantries across the state. Interviews were conducted with food pantry managers and volunteers to examine various issues, challenges, and successes related to their operations. All interviews were transcribed and coded using a systematic analysis of codes to generate major themes related to pantry management protocols. Using an ecological framework, our study yielded five major areas of consideration for optimal pantry management: volunteer recruitment, operating and control systems, patron needs, collaboration, and advocacy

Spontaneous DNA damage to the nuclear genome promotes senescence,redox imbalance and aging

Accumulation of senescent cells over time contributes to aging and age-related diseases. However, what drives senescence in vivo is not clear. Here we used a genetic approach to determine if spontaneous nuclear DNA damage is sufficient to initiate senescence in mammals. Ercc1-/Δ mice with reduced expression of ERCC1-XPF endonuclease have impaired capacity to repair the nuclear genome. Ercc1-/Δ mice accumulated spontaneous, oxidative DNA damage more rapidly than wild-type (WT) mice. As a consequence, senescent cells accumulated more rapidly in Ercc1-/Δ mice compared to repair-competent animals. However, the levels of DNA damage and senescent cells in Ercc1-/Δ mice never exceeded that observed in old WT mice. Surprisingly, levels of reactive oxygen species (ROS) were increased in tissues of Ercc1-/Δ mice to an extent identical to naturally-aged WT mice. Increased enzymatic production of ROS and decreased antioxidants contributed to the elevation in oxidative stress in both Ercc1-/Δ and aged WT mice. Chronic treatment of Ercc1-/Δ mice with the mitochondrial-targeted radical scavenger XJB-5–131 attenuated oxidative DNA damage, senescence and age-related pathology. Our findings indicate that nuclear genotoxic stress arises, at least in part, due to mitochondrial-derived ROS, and this spontaneous DNA damage is sufficient to drive increased levels of ROS, cellular senescence, and the consequent age-related physiological decline

A genome-wide association study of anorexia nervosa suggests a risk locus implicated in dysregulated leptin signaling

J. Kaprio, A. Palotie, A. Raevuori-Helkamaa ja S. Ripatti ovat työryhmän Eating Disorders Working Group of the Psychiatric Genomics Consortium jäseniä. Erratum in: Sci Rep. 2017 Aug 21;7(1):8379, doi: 10.1038/s41598-017-06409-3We conducted a genome-wide association study (GWAS) of anorexia nervosa (AN) using a stringently defined phenotype. Analysis of phenotypic variability led to the identification of a specific genetic risk factor that approached genome-wide significance (rs929626 in EBF1 (Early B-Cell Factor 1); P = 2.04 x 10(-7); OR = 0.7; 95% confidence interval (CI) = 0.61-0.8) with independent replication (P = 0.04), suggesting a variant-mediated dysregulation of leptin signaling may play a role in AN. Multiple SNPs in LD with the variant support the nominal association. This demonstrates that although the clinical and etiologic heterogeneity of AN is universally recognized, further careful sub-typing of cases may provide more precise genomic signals. In this study, through a refinement of the phenotype spectrum of AN, we present a replicable GWAS signal that is nominally associated with AN, highlighting a potentially important candidate locus for further investigation.Peer reviewe

Common Genetic Variation And Age at Onset Of Anorexia Nervosa

Background Genetics and biology may influence the age at onset of anorexia nervosa (AN). The aims of this study were to determine whether common genetic variation contributes to AN age at onset and to investigate the genetic associations between age at onset of AN and age at menarche. Methods A secondary analysis of the Psychiatric Genomics Consortium genome-wide association study (GWAS) of AN was performed which included 9,335 cases and 31,981 screened controls, all from European ancestries. We conducted GWASs of age at onset, early-onset AN (< 13 years), and typical-onset AN, and genetic correlation, genetic risk score, and Mendelian randomization analyses. Results Two loci were genome-wide significant in the typical-onset AN GWAS. Heritability estimates (SNP-h2) were 0.01-0.04 for age at onset, 0.16-0.25 for early-onset AN, and 0.17-0.25 for typical-onset AN. Early- and typical-onset AN showed distinct genetic correlation patterns with putative risk factors for AN. Specifically, early-onset AN was significantly genetically correlated with younger age at menarche, and typical-onset AN was significantly negatively genetically correlated with anthropometric traits. Genetic risk scores for age at onset and early-onset AN estimated from independent GWASs significantly predicted age at onset. Mendelian randomization analysis suggested a causal link between younger age at menarche and early-onset AN. Conclusions Our results provide evidence consistent with a common variant genetic basis for age at onset and implicate biological pathways regulating menarche and reproduction.Peer reviewe
