Targeted qPCR and non-targeted amplicon sequencing of 16S rRNA genes within sediment layers identified the anaerobic ammonium oxidation (anammox) niche and characterized microbial community changes attributable to freshwater mussels. Anammox bacteria were normally distributed (Shapiro-Wilk normality test, W-statistic =0.954, p = 0.773) between 1 and 15 cm depth and were increased by a factor of 2.2 (p < 0.001) at 3 cm below the water-sediment interface when mussels were present. Amplicon sequencing of sediment at depths relevant to mussel burrowing (3 and 5 cm) showed that mussel presence reduced observed species richness (p = 0...

Few accounts describe predator-prey interactions between common bottlenose dolphins (Tursiops truncatus Montagu 1821) and marine catfish (Ariopsis felis Linnaeus 1766, Bagre marinus Mitchill 1815). Over the course of 50,167 sightings of bottlenose dolphin groups in Mississippi Sound and along the Florida coast of the Gulf of Mexico, severed catfish heads were found floating and exhibiting movements at the surface in close proximity to 13 dolphin groups that demonstrated feeding behavior. These observations prompted a multi-disciplinary approach to study the predator-prey relationship between bottlenose dolphins and marine catfish...

Congenital amegakaryocytic thrombocytopenia is a rare disorder causing thrombocytopenia that progresses to pancytopenia and bone marrow failure if untreated. It is caused by variants in the MPL gene which encodes the thrombopoeitin receptor. In this report, we review 5 cases of congenital amegakaryocytic thrombocytopenia, all of whom belong to the Mississippi Band of Choctaw Indians. There are 2 common variants in these cases: R90X and R537W. One variant was previously reported only once and had unclear significance at that time...

Gulf menhaden (Brevoortia patronus) exhibited unprecedented juvenile recruitment in 2010 during the year of the Deepwater Horizon well blowout, exceeding the prior 39-year mean by more than four standard deviations near the Mississippi River. Abundance of that cohort remained exceptionally high for two subsequent years as recruits moved into older age classes. Such changes in this dominant forage fish population can be most parsimoniously explained as consequences of release from predation. Contact with crude oil induced high mortality of piscivorous seabirds, bottlenose dolphin (Tursiops truncatus), waders, and other fish-eating marsh birds, all of which are substantial consumers of Gulf menhaden...

BACKGROUND: Glyphosate-resistance in Amaranthus palmeri, one of the most prevalent herbicide-resistant weeds in the United States, is due to amplification and increased expression of the gene encoding the target site of glyphosate, 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS). The EPSPS gene and the surrounding 287 kilobases (kb) of amplified sequence is unique to glyphosate-resistant plants and termed the EPSPS cassette. It has only been sequenced from one A. palmeri population from Mississippi...

Surgery is the most important curative treatment modality for patients with early-stage non-small cell lung cancer (NSCLC). We examined the pattern of surgical resection for NSCLC in a high incidence and mortality region of the United States over a 10-year period (2004-2013) in the context of a regional surgical quality improvement initiative. We abstracted patient-level data on all resections at 11 hospitals in 4 contiguous Dartmouth Hospital Referral Regions in North Mississippi, East Arkansas, and West Tennessee...

This study examined the practices, personal motivation, and barriers of African American communities in Mississippi regarding their dietary practices. We selected the Metro Jackson Area comprised of Hinds, Madison and Rankin Counties because it is a combination of urban and rural communities. The sample consisted of 70 participants from seven sites. A total of seven focus groups responded to six questions to assess practices, personal motivation, and barriers to dietary practices: (1) Where in your community can you access fresh fruits and vegetables? (2) How many meals a day should a person eat? (3) What would you consider to be a healthy breakfast, lunch and dinner? (4) What would you consider to be a healthy snack? (5) What do you consider to be your motivations for eating healthy? (6) What do you consider to be your barriers to eating healthy? Each of the seven focus groups consisted of 6 to 12 participants and provided details of their dietary practices...

Isoscape refinement is an essential component for accurately predicting region-of-origin in forensic investigations involving isotope analysis of unidentified human remains. Stable oxygen (δ(18) O) and hydrogen (δ(2) H) isotopes were measured from 57 tap water samples collected across Mississippi to model refined isoscapes for the state. A tap water conversion equation, δ(18) Otw =1.64 δ(18) Op-31.35, was developed for the southeastern USA to test the prediction accuracy of the δ(18) Otw isoscape using individuals with known residential histories...

  Previous studies have identified relationships between nutrient exports and upstream conditions, but have often disconnected interpretations from hydrological flows and changes. Here, we investigated basic relationships between largely flow-independent nutrient concentrations and two key descriptors of upstream landscape and human activity: population density and arable land cover. Consistent data were gathered from previous studies of the Baltic Sea and Mississippi River basins. These data span wide ranges of subcatchment scales, hydroclimatic conditions, and landscape characteristics...

INTRODUCTION: In 2015, about 1.5 million adults in Mississippi were overweight or obese. Obesity is associated with increased risk for diabetes and cardiovascular problems. We examined trends in the prevalence of overweight, obesity, and extreme obesity from 2001 through 2010 and 2011 through 2015. METHODS: We used data from the Mississippi Behavioral Risk Factor Surveillance System to analyze trends in the prevalence of overweight, obesity, and extreme obesity among adults from 2001 through 2010 and 2011 through 2015...

Abundance estimates are essential for estimating the viability of populations and the risks posed by alternative management actions. An effort to estimate abundance via a repeated mark-recapture experiment may fail to recapture marked individuals. We present a framework for obtaining lower bounds on abundance in the absence of recaptures for both panmictic and spatially-structured populations. We applied this nil-recapture method to data from a 12-year survey of pallid sturgeon (Scaphirhynchus albus) in the lower and middle Mississippi River; none of the 241 individuals marked were recaptured in the survey...

In 2011, poly- and perfluoroalkyl substances (PFASs) were analyzed in surface water and fish fillet samples taken from Pool 2 of the Upper Mississippi River, a 33-mile stretch inclusive of the Minneapolis/St. Paul, Minnesota metropolitan area. Approximately 100 each of bluegill (BGS), freshwater drum (FWD), smallmouth bass (SMB), and white bass (WHB) were sampled within the study area. Surface water samples were also collected from each of the 10 sampling reaches established for the study. Water and fillet samples were analyzed for perfluorinated carboxylic acids (PFCAs) (C4-C12), perfluorinated sulfonic acids (PFSAs) (C4, C6, and C8), and perfluorooctane sulfonamide (FOSA)...

BACKGROUND: Given the positive association between primary care and overall health, several health plans are offering doctors' visits without patient copay, with the intent to increase primary care use. However, the effectiveness of these offers has not been established in the literature. OBJECTIVE: To evaluate the impact of a free primary care provider (PCP) office visit offered by a health plan on primary care-seeking behaviors. METHODS: This nonrandomized concurrent control study used event/trials logistic regression to compare the differences in primary care utilization between new exchange enrollees in Mississippi who were offered a free nonpreventive PCP visit and concurrent controls from Georgia and Tennessee who were not offered a free visit, between January 1, 2014, and December 31, 2014, which was the first year of the exchange plans...

Many women continue to become infected with HIV, particularly in the Southeastern USA, despite widespread knowledge about methods to prevent its sexual transmission. This grounded theory investigation examined the decision-making process women use to guide their use or non-use of self-protective measures when engaging in sexual activity. Participants included women in the Mississippi cohort of the Women's Interagency HIV Study who were infected with or at high risk for HIV. Theoretical sampling was used to recruit a sample of 20 primarily African American women aged between 26 and 56 years, living in rural and urban areas...

BACKGROUND: Heart disease (HD) is the leading cause of death among Mississippians. However, trends in mortality rates for HD subtypes in Mississippi have not been adequately described. This study examined trends in mortality rates for HD subtypes among adults in Mississippi from 1980 through 2013. METHODS: We used Mississippi Vital Statistics data to calculate age-specific mortality rates for HD subtypes for Mississippians age 35 and older. Cases were identified via underlying cause of death codes from the International Classification of Diseases, Ninth Revision (ICD-9) and Tenth Revision (ICD-10)...

Paracloeodes Day is a western hemisphere genus with 20 species, but only three of these valid species are known from continental North and Central America. Based on available literature comparisons, species-level identifications of these three species can be difficult. Considering the apparent similarity between them, the main objective of this study was to examine type and other material housed in the Purdue Entomological Research Collection and the University of Minnesota in order to evaluate species status and to elucidate additional diagnostic characters...
