Expansion of Access to Healthy Foods for SNAP-Eligible Households to Reduce Food Insecurity Through the Creation of an Accountable Care Community in Cumberland County, North Carolina

The system of food insecurity in Cumberland County, North Carolina does not provide adequate food options to the community. It creates limited access to affordable local produce and impacts households living in poverty that are not maximizing the use of Supplemental Nutrition Assistance Program (SNAP) benefits, amplifying poor health outcomes. An Accountable Care Community (ACC) will be established in Cumberland County, North Carolina, to address the social determinant of health of economic stability by reducing food insecurity. This will be accomplished through the expansion of access to healthy foods by enacting a policy to allow SNAP benefit purchasing power at local farmers’ markets in the county. The ACC partners include, but are not limited to, the Cumberland County Public Health Department, Cumberland County Department of Social Services, the Fayetteville Farmers’ Market Association, and local vendors and farmers.Master of Public Healt

The BOLD platform has a private, password-protected workbench for the steps from specimen data entry to data validation (see details in Data Records), and a public data portal for the release of data in various formats. The latter is accessible through an API (http://www.boldsystems.org/index.php/resources/api?type=webservices) that can also be controlled through R75 with the package ‘bold’76.Peer reviewedPublisher PD

The James Webb Space Telescope Mission

Twenty-six years ago a small committee report, building on earlier studies, expounded a compelling and poetic vision for the future of astronomy, calling for an infrared-optimized space telescope with an aperture of at least $4m$. With the support of their governments in the US, Europe, and Canada, 20,000 people realized that vision as the $6.5m$ James Webb Space Telescope. A generation of astronomers will celebrate their accomplishments for the life of the mission, potentially as long as 20 years, and beyond. This report and the scientific discoveries that follow are extended thank-you notes to the 20,000 team members. The telescope is working perfectly, with much better image quality than expected. In this and accompanying papers, we give a brief history, describe the observatory, outline its objectives and current observing program, and discuss the inventions and people who made it possible. We cite detailed reports on the design and the measured performance on orbit.Comment: Accepted by PASP for the special issue on The James Webb Space Telescope Overview, 29 pages, 4 figure

Less Bone Loss With Maraviroc- Versus Tenofovir-Containing Antiretroviral Therapy in the AIDS Clinical Trials Group A5303 Study

Background. There is a need to prevent or minimize bone loss associated with antiretroviral treatment (ART) initiation. We compared maraviroc (MVC)- to tenofovir disoproxil fumarate (TDF)–containing ART

Evolution of the ToxB gene in Pyrenophora tritici-repentis and related species

Pyrenophora tritici-repentis (tan spot) is a destructive foliar pathogen of wheat with global impact. This ascomycete fungus possesses a highly plastic open pangenome shaped by the gain and loss of effector genes. This study investigated the allelic variations in the chlorosis-encoding gene ToxB across 422 isolates representing all identified pathotypes and worldwide origins. To gain better insights into ToxB evolution, we examined its presence and variability in other Pyrenophora spp. A ToxB haplotype network was constructed, revealing the evolutionary relationships of this gene (20 haplotypes) across four Pyrenophora species. Notably, toxb, the homolog of ToxB, was detected for the first time in the barley pathogen Pyrenophora teres. The ToxB/toxb genes display evidence of selection that is characterized by loss of function, duplication, and diverse mutations. Within the ToxB/toxb open reading frame, 72 mutations were identified, including 14 synonymous, 55 nonsynonymous, and 3 indel mutations. Remarkably, a, ∼5.6-kb Copia-like retrotransposon, named Copia-1_Ptr, was found inserted in the toxb gene of a race 3 isolate. This insert disrupted the ToxB gene's function, a first case of effector gene disruption by a transposable element in P. tritici-repentis. Additionally, a microsatellite with 25 nucleotide repeats (0 to 10) in the upstream region of ToxB suggested a potential mechanism influencing ToxB expression and regulation. Exploring ToxB-like protein distribution in other ascomycetes revealed the presence of ToxB-like proteins in 19 additional species, including the Leotiomycetes class for the first time. The presence/absence pattern of ToxB-like proteins defied species relatedness compared with a phylogenetic tree, suggesting a past horizontal gene transfer event during the evolution of the ToxB gene.

Prediction of spontaneous preterm labour in at-risk pregnant women

The ability to recognise women who are at-risk of preterm labour (PTL) is often difficult. Over 50% of women who are identified with factors associated with an increased risk of preterm birth will ultimately deliver at term. The cervicovaginal fluid (CVF) comprises a range of proteins secreted by gestational tissues, making it an ideal candidate for the screening of differentially expressed proteins associated with PTL. CVF samples were collected from at-risk asymptomatic women. Two-dimensional gel electrophoresis techniques were used to examine the CVF proteome of women who spontaneously delivered preterm 11-22 days later compared with gestation-matched women who delivered at term. Five candidate biomarkers were selected for further validation in a larger independent cohort of asymptomatic women. Thioredoxin (TXN) and interleukin 1 receptor antagonist (IL1RN) concentrations in the CVF were found to be significantly reduced up to 90 days prior to spontaneous PTL compared with women who subsequently delivered at term. TXN was able to predict spontaneous PTL within 28 days after sampling with a high positive predictive value (PPV) and negative predictive value (NPV) of 75.0% and 96.4% respectively. IL1RN also showed comparable PPV and NPV of 72.7% and 95.7% respectively. The discovery of these differentially expressed proteins may assist in the development of a new predictive bedside test in identifying asymptomatic women who have an increased risk of spontaneous PTL

Global arthropod beta-diversity is spatially and temporally structured by latitude

Global biodiversity gradients are generally expected to reflect greater species replacement closer to the equator. However, empirical validation of global biodiversity gradients largely relies on vertebrates, plants, and other less diverse taxa. Here we assess the temporal and spatial dynamics of global arthropod biodiversity dynamics using a beta-diversity framework. Sampling includes 129 sampling sites whereby malaise traps are deployed to monitor temporal changes in arthropod communities. Overall, we encountered more than 150,000 unique barcode index numbers (BINs) (i.e. species proxies). We assess between site differences in community diversity using beta-diversity and the partitioned components of species replacement and richness difference. Global total beta-diversity (dissimilarity) increases with decreasing latitude, greater spatial distance and greater temporal distance. Species replacement and richness difference patterns vary across biogeographic regions. Our findings support long-standing, general expectations of global biodiversity patterns. However, we also show that the underlying processes driving patterns may be regionally linked.peerReviewe
