    Introduction: Appalachia, particularly Rural East Tennessee, has been and continues to be disproportionately impacted by opioid use disorder and its many tragic ramifications. Purpose: Community-engaged strategies can inform and support the development of relevant prevention efforts. Hence, people connected to a ten-county rural Appalachian region in East Tennessee were asked to identify and prioritize strengths and challenges related to opioid use disorder (OUD). Methods: Adult community members (n=577) completed a brief survey administered across 11 days in 2019. Results: Of the respondents, 85.3% never had been addicted to opioids, but 74.0% had someone close to them with OUD. The most frequently selected community strength was support for people with OUD to seek help and the most frequently selected challenge was lack of treatment and recovery services. People with personal OUD experience reported significantly higher mean levels of OUD-related stigma compared to persons without such experience. Implications: The number of respondents indicates a local concern and commitment related to OUD in rural Appalachia. The findings prioritized areas of focus—both in needs to be addressed and strengths on which to capitalize. These community insights will guide the selection and development of OUD-related overdose prevention for this region

    Background College students are at heightened risk for negative psychological outcomes due to COVID-19. We examined the prevalence of psychological distress and its association with social isolation among public university students in the southern United States. Methods A cross-sectional survey was emailed to all University of North Carolina-Chapel Hill students in June 2020 and was open for two weeks. Students self-reported if they were self-isolating none, some, most, or all of the time. Validated screening instruments were used to assess clinically significant symptoms of depression, loneliness, and increased perceived stress. The data was weighted to the complete student population. Results 7,012 completed surveys were included. Almost two-thirds (64%) of the students reported clinically significant depressive symptoms and 65% were categorized as lonely. An estimated 64% of students reported self-isolating most or all of the time. Compared to those self-isolating none of the time, students self-isolating some of the time were 1.78 (95% CI 1.37, 2.30) times as likely to report clinically significant depressive symptoms, and students self-isolating most or all of the time were 2.12 (95% CI 1.64, 2.74) and 2.27 (95% CI 1.75, 2.94) times as likely to report clinically significant depressive symptoms, respectively. Similar associations between self-isolation and loneliness and perceived stress were observed. Conclusions The prevalence of adverse mental health indicators among this sample of university students in June 2020 was exceptionally high. University responses to the COVID-19 pandemic should prioritize student mental health and prepare a range of support services to mitigate mental health consequences as the pandemic continues to evolve

    BACKGROUND: Previous genome-wide association studies (GWAS) have identified 42 loci (P < 5 × 10-8) associated with risk of colorectal cancer (CRC). Expanded consortium efforts facilitating the discovery of additional susceptibility loci may capture unexplained familial risk. METHODS: We conducted a GWAS in European descent CRC cases and control subjects using a discovery-replication design, followed by examination of novel findings in a multiethnic sample (cumulative n = 163 315). In the discovery stage (36 948 case subjects/30 864 control subjects), we identified genetic variants with a minor allele frequency of 1% or greater associated with risk of CRC using logistic regression followed by a fixed-effects inverse variance weighted meta-analysis. All novel independent variants reaching genome-wide statistical significance (two-sided P < 5 × 10-8) were tested for replication in separate European ancestry samples (12 952 case subjects/48 383 control subjects). Next, we examined the generalizability of discovered variants in East Asians, African Americans, and Hispanics (12 085 case subjects/22 083 control subjects). Finally, we examined the contributions of novel risk variants to familial relative risk and examined the prediction capabilities of a polygenic risk score. All statistical tests were two-sided. RESULTS: The discovery GWAS identified 11 variants associated with CRC at P < 5 × 10-8, of which nine (at 4q22.2/5p15.33/5p13.1/6p21.31/6p12.1/10q11.23/12q24.21/16q24.1/20q13.13) independently replicated at a P value of less than .05. Multiethnic follow-up supported the generalizability of discovery findings. These results demonstrated a 14.7% increase in familial relative risk explained by common risk alleles from 10.3% (95% confidence interval [CI] = 7.9% to 13.7%; known variants) to 11.9% (95% CI = 9.2% to 15.5%; known and novel variants). A polygenic risk score identified 4.3% of the population at an odds ratio for developing CRC of at least 2.0. CONCLUSIONS: This study provides insight into the architecture of common genetic variation contributing to CRC etiology and improves risk prediction for individualized screenin

    Discovery of common and rare genetic risk variants for colorectal cancer.

    To further dissect the genetic architecture of colorectal cancer (CRC), we performed whole-genome sequencing of 1,439 cases and 720 controls, imputed discovered sequence variants and Haplotype Reference Consortium panel variants into genome-wide association study data, and tested for association in 34,869 cases and 29,051 controls. Findings were followed up in an additional 23,262 cases and 38,296 controls. We discovered a strongly protective 0.3% frequency variant signal at CHD1. In a combined meta-analysis of 125,478 individuals, we identified 40 new independent signals at P < 5 × 10-8, bringing the number of known independent signals for CRC to ~100. New signals implicate lower-frequency variants, Krüppel-like factors, Hedgehog signaling, Hippo-YAP signaling, long noncoding RNAs and somatic drivers, and support a role for immune function. Heritability analyses suggest that CRC risk is highly polygenic, and larger, more comprehensive studies enabling rare variant analysis will improve understanding of biology underlying this risk and influence personalized screening strategies and drug development.Goncalo R Abecasis has received compensation from 23andMe and Helix.

    This study examined the psychometric properties of the Revised Child Anxiety and Depression Scale in a large sample of youth from the Southern United States. The authors aimed to determine (a) if the established six-factor Revised Child Anxiety and Depression Scale structure could be replicated in this Southern sample and (b) if scores were associated with measurement invariance across African American and Caucasian youth representative of youth from this region of the United States. The established six-factor model evidenced the best fit in comparison to one-, two-, and five-factor models in the total sample (N = 12,695), as well as in the African American (n = 4,906) and Caucasian (n = 6,667) subsamples. Multigroup confirmatory factor analysis also supported measurement invariance across African American and Caucasian youth at the levels of equal factor structure and equal factor loadings. Noninvariant item intercepts were identified, however, indicating differential functioning for a subset of items. Clinical and measurement implications of these findings are discussed and new norms are presented

    Geophilosophies of Masculinity

    No full text
    Geophilosophy is a placeholder for things we cannot yet do, things we hope to do, and things that we have failed to do so far. This issue of Angelaki aspires towards ways of doing philosophy, geography and gender studies that stray from the analytical comforts of philosophical reasoning, and from the sociological certainties that dominate the study of masculinity. In particular, it brings a sexed and gendered body to extant Deleuze-Guattarian scholarship, while prompting a thirst for creativity and ambivalence to masculinity research. Each article explores the ways in which lived cultures of masculinity might be read across uneven political formations and aesthetic practices, while calling into question tacit understandings of where “masculinity” begins and ends. In doing so, the collection teases out the ethical and methodological implications of poststructuralist approaches to gender in a range of disciplines, including cultural geography, art criticism, sociology, and disability studies
