Information about wetland dynamics remains a major missing gap in characterizing, understanding, and projecting changes in atmospheric methane and terrestrial water storage. A review of current satellite methods to delineate and monitor wetland change shows some recent advances, but much improved sensing technologies are still needed for wetland mapping, not only to provide more accurate global inventories but also to examine changes spanning multiple decades. Global Navigation Satellite Systems Reflectometry (GNSS-R) signatures from aircraft over the Ebro River Delta in Spain and satellite measurements over the Mississippi River and adjacent watersheds demonstrate that inundated wetlands can be identified under different vegetation conditions including a dense rice canopy and a thick forest with tall trees, where optical sensors and monostatic radars provide limited capabilities...

OBJECTIVES: To understand where transmission of Zika virus has the highest likelihood to occur in the contiguous United States with regard to its transmission both sexually and via Aedes aegypti mosquito bites. METHODS: We evaluated the 2 routes of transmission risk with predictors of sexually transmitted infections (percentage women of childbearing age, birthrate, gonorrhea and chlamydia rates, concentrated disadvantage) as a surrogate for unprotected sexual activity and the demographic distribution of the A...

We review the development of a disaster health care response system in Mississippi aimed at improving disaster response efforts. Large-scale disasters generate many injured and ill patients, which causes a significant utilization of emergency health care services and often requires external support to meet clinical needs. Disaster health care services require a solid infrastructure of coordination and collaboration to be effective. Following Hurricane Katrina, the state of Mississippi implemented best practices from around the nation to establish a disaster health care response system...

This study considers how shared devotion to the Virgin of Guadalupe among Mexican immigrants in rural Mississippi buffers the effects of immigration stress. Rural destinations lacking social services can quickly compound the already stressful experience of immigration. Guadalupe devotion provides a way of coping with the daily life stressors of immigration. We test the hypothesis that high consonance in the cultural model of Guadalupan devotion will moderate the adverse health effects of immigration stress...

This study tested whether and how dissolved chemicals might assist food recognition in two filter-feeding fishes, the silver (Hypophthalmichthys molitrix) and the bighead carp (H. nobilis). These species evolved in Asia, are now invasive in the Mississippi River, and feed voraciously on microparticles including plankton. The food habits and biology of these carps are broadly similar to many filter-feeding fish, none of whose chemical ecology has been examined. We conducted five experiments. First, we demonstrated that buccal-pharngeal pumping (BPP), a behavior in which fish pump water into their buccal cavities, is responsible for sampling food: BPP activity in both silver and bighead carps was low and increased nearly 25-fold after exposure to a filtrate of a planktonic food mixture (P < 0...

The two municipal drinking water systems of New Orleans, LA, USA were sampled to compare microbiology of independent systems that treat the same surface water from the Mississippi River. To better understand temporal trends and sources of microbiology delivered to taps, these treatment plants and distribution systems were subjected to source-to-tap sampling over four years. Both plants employ traditional treatment by chloramination, applied during or after settling, followed by filtration before distribution in a warm, low water age system...

Coastal Louisiana has lost about 5,000 km(2) of wetlands over the past century and concern exists whether remaining wetlands will persist while facing some of the world's highest rates of relative sea-level rise (RSLR). Here we analyse an unprecedented data set derived from 274 rod surface-elevation table-marker horizon stations, to determine present-day surface-elevation change, vertical accretion and shallow subsidence rates. Comparison of vertical accretion rates with RSLR rates at the land surface (present-day RSLR rates are 12±8 mm per year) shows that 65% of wetlands in the Mississippi Delta (SE Louisiana) may keep pace with RSLR, whereas 58% of the sites in the Chenier Plain (SW Louisiana) do not, rendering much of this area highly vulnerable to RLSR...

Discrete cystic or tumorous intraosseous lesions can arise from a variety of benign and malignant conditions as well as trauma and infection. They are clinically rarely observed in the calcaneus. A fourteen-to-seventeen-year-old subadult recovered from a Late Woodland (∼AD 800-1100) period mortuary context in the Mississippi River Valley of central Illinois presents with a single lytic intraosseous lesion on the posterior right calcaneus that bilaterally perforates the cortex. The lesion, although primarily anterior to the epiphyseal plate, does breach it...

Gay and bisexual men and other men who have sex with men (MSM) account for more than two thirds of new HIV infections in the U.S., with Black MSM experiencing the greatest burden. Antiretroviral pre-exposure prophylaxis (PrEP) can reduce MSM's vulnerability to HIV infection. Uptake of PrEP has been limited, particularly among racial and ethnic minority MSM. Four semi-structured focus groups with gay and bisexual men and other MSM at risk for HIV infection were convened in Boston and Jackson in late 2013. The analysis plan utilized a within-case, across-case approach to code and analyze emerging themes, and to compare results across the two cities...

BACKGROUND: Little is known about the lifetime risk of human immunodeficiency virus (HIV) diagnosis among US men who have sex with men (MSM), trends in risk and how risk varies between populations. METHODS: We used census and HIV surveillance data to construct life tables to estimate the cumulative risk of HIV diagnosis among cohorts of MSM born 1940 to 1994 in King County, Washington (KC) and Mississippi (MS). RESULTS: The cumulative risk of HIV diagnosis progressed in 3 phases...

On 28th April, 2014, a tornado left much of Louisville, MS and the local hospital, Winston Medical Center, in ruin. In the USA, temporary hospital solutions have been used to augment the mainstream healthcare system since the American Civil War. As memories fade, however, the necessary readiness for a temporary hospital also fades, at times leaving a patchwork of resources either underfunded or abandoned. With the creation of the Hospital Preparedness Program, several temporary hospital solutions were created in various states across the USA...

INTRODUCTION: Obesity and chronic diseases disproportionately affect African-American women in the rural South (US) and may be influenced by adherence to a typical Southern-style diet. There is a need to examine dietary patterns of this population and to determine if consumption of nutritionally rich foods like nuts is associated with consumption of other nutritious foods. The objectives of this study were to identify (1) dietary patterns of overweight/obese African-American women in the rural South; (2) the role that nuts play in the diet; (3) and adherence to federal food group recommendations across dietary patterns...

Background Excessive gambling is considered to be a part of the addiction spectrum. Stress-like emotional states are a key feature both of pathological gambling (PG) and of substance addiction. In substance addiction, stress symptomatology has been attributed in part to "anti-reward" allostatic neuroadaptations, while a potential involvement of anti-reward processes in the course of PG has not yet been investigated. Methods To that end, individuals with PG (n = 22) and mentally healthy subjects (n = 13) were assessed for trauma exposure and post-traumatic stress symptomatology (PTSS) using the Life Events Checklist and the Civilian Mississippi Scale, respectively...

Although the etiology of obesity is complex, social disparities are gaining attention for their contribution to obesity. The aim of this study was to estimate prevalence of obesity and to explore the associations between socio-demographic characteristics and obesity by race in Mississippi. Data from the 2014 Mississippi Behavior Risk Factors Surveillance System (BRFSS) were used in this study (n = 3794). Descriptive statistics, Chi-square tests and logistic regressions were conducted using SAS Proc. Survey procedures to account for BRFSS's multistage complex survey design and sample weights...

The present study aimed to examine the perceptions of African American communities regarding the involvement of political leaders in facilitating policy and environmental change promoting healthy eating and physical activity. 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 were asked to respond to one question to assess political leaders' involvement in healthy living: "When you think about your political leaders that you have in the Jackson, Mississippi area, do any of them promote healthy eating and physical activity?" Focus groups consisted of six to 12 participants and were asked to comment on their participation in physical activity...
