Subsurface controls on mainland marsh shoreline response during barrier island transgressive submergence

Many recent studies have sought to understand the response of barrier islands and their attendant marshes to sea level rise. The Mississippi River delta plain, specifically the Chandeleur Islands and associated interior wetlands in eastern Louisiana, serves as an excellent natural laboratory for studying these responses. This region is presently undergoing the highest rates of shoreline erosion (\u3e 15 m yr -1) in North America as wetlands are converted to open water in a regime of subsidence-driven rapid relative sea-level rise (~1 cm yr-1). Three conceptual models were developed based on the geomorphic relationships observed in the marsh that describe and predict shoreline processes as the Chandeleur Islands continue to disintegrate and submerge. These models indicate that shells are the dominant shoreline-forming material in the marsh due to the lack of sand-rich strata in the subsurface of the marsh

Exploitation of adult aggregation behavior for management of the European corn borer

A relative sampling technique was used daily to sample for adult European corn borer (ECB), Ostrinia nubilalis (Hubner), in aggregation sites within the grass. The flush bar, a meter-long aluminum bar, was swept through the grass canopy in ten meter-long sweeps and numbers of ECB moths were counted as they flushed from the 10 m[superscript]2 area. European corn borer egg masses were scouted within hybrid seed corn fields adjacent to flush bar sampling sites on a three to five day schedule;Daily numbers of flushed moths were averaged within samples and accumulated between scouting dates. Egg mass numbers were accumulated in a running sum over scouting dates. The running sum of egg masses was regressed on the running sum of mean adult numbers. The regression analysis confirmed a dependent relationship between egg mass numbers in the field on adult numbers in the grass around the field. A predictive equation was established to estimate egg mass levels within the field by adult numbers flushed in the grass;An oviposition preference by ECB females was documented for scouted egg mass numbers within hybrid seed fields. ECB females deposited greater numbers of egg masses on the tassled male inbred than on the detassled female inbred. Differences also existed between locations of egg masses on the plant. The majority of egg masses were located on the ear leaf and three leaves below. There was a trend for the male inbred to have a greater proportion of egg masses above the ear than the female inbred. Although the male inbred received larger numbers of egg masses, the ratio of larvae and tunnels/egg was not greater than that of the female inbred;A partial plant scouting technique for European corn borer egg masses was compared with the standard whole plant examination technique. The level of accuracy obtained by partial plant examination was found to be lower than that suggested for hybrid plants. There was a trend for a greater recovery rate of egg masses on the male inbred than on the female inbred;The efficacy of an adult directed control strategy applied to the grass was compared with a standard larval field treatment. Methomyl applied in the grass for adult control in combination with fenvalerate applied to the field for larval control significantly reduced larval numbers and tunnel damage. There were insignificant differences between the grass treatment, the field treatment and the untreated check

Alterations in Blood-Brain Barrier Function Following Acute Hypertension: Comparison of the Blood-to-Brain Transfer of Horseradish Peroxidase with That of Alpha-Aminoisobutyric Acid

The blood-brain barrier (BBB) selectively restricts the blood-to-brain passage of many solutes owing to unique properties of cerebrovascular endothelial cell membranes. This selective blood/brain interface participates in the maintenance of brain homeostasis by controlling nutrient, gas, and fluid exchange necessary for brain function. Normal BBB function can be altered under various pathological and experimental conditions, allowing the transfer into brain parenchyma of blood-borne solutes normally excluded. To date, experimental study of the BBB has been accomplished primarily through the use of two different methodological approaches. Some investigators have focused on the barrier\u27s morphological correlates and its morphopathological alteration under various pathological conditions. Other investigators have attempted to define the physiological transport properties of the BBB. Morphological studies have employed, for the most part, large molecular weight (MW) tracers to detect morphological alterations underlying increased permeability. Physiological studies, employing smaller, more physiologic tracers have been successful in describing, quantitatively, certain functional aspects of blood-to-brain transfer. The current work attempts to merge these two approaches and to consider barrier function/dysfunction from both a morphological and a functional perspective. Specifically, the study compares in rats, following acute hypertension (a condition well-known to elicit BBB alteration), the cerebrovascular passage of C-alpha-aminois obutyric acid (AIB), a small MW tracer employed in quantitative physiologic barrier studies, and that of horseradish peroxidase (HRP), a large MW protein tracer traditionally employed in morphological barrier studies. The blood-to-brain passage of AIB and HRP were compared, following acute hypertension, with regard to both the topographical distributions of the tracer extravasation patterns and the magnitude of tracer extravasation at two different levels of hypertension. Quantitative measures of cerebrovascular AIB transfer were obtained through macroautoradiography and computerized image analysis. The data, both qualitative and quantitative, revealed dramatic focal permeability increases to AIB in some brain loci which also showed permeability increases to HRP. Such loci included the cerebral cortices and the thalamus. However, many brain regions, such as the caudate-putamen, cerebellum, and brainstem, showed more subtly-elevated AIB passage where no corresponding HRP passage was observed. Linear regression analysis of the physiologic data showed that the rate of cerebrovascular AIB transfer was positively related to the abruptness of the onset of hypertension and not related to other physiologic parameters of the hypertensive insult. The qualitative and quantitative results of this study suggest that traditional morphological barrier studies a lone do not reveal all aspects of altered barrier status and that multiple mechanisms underlying increased BBB permeability may operate simultaneously during BBB dysfunction

Bezlotoxumab for prevention of recurrent Clostridium difficile infection in patients at increased risk for recurrence

Background: Bezlotoxumab is a human monoclonal antibody against Clostridium difficile toxin B indicated to prevent C. difficile infection (CDI) recurrence (rCDI) in adults at high risk for rCDI. This post hoc analysis of pooled monocolonal antibodies for C.difficile therapy (MODIFY) I/II data assessed bezlotoxumab efficacy in participants with characteristics associated with increased risk for rCDI. Methods: The analysis population was the modified intent-to-treat population who received bezlotoxumab or placebo (n = 1554) by risk factors for rCDI that were prespecified in the statistical analysis plan: age ≥65 years, history of CDI, compromised immunity, severe CDI, and ribotype 027/078/244. The proportion of participants with rCDI in 12 weeks, fecal microbiota transplant procedures, 30-day all cause and CDI-associated hospital readmissions, and mortality at 30 and 90 days after randomization were presented. Results: The majority of enrolled participants (75.6%) had ≥1 risk factor; these participants were older and a higher proportion had comorbidities compared with participants with no risk factors. The proportion of placebo participants who experienced rCDI exceeded 30% for each risk factor compared with 20.9% among those without a risk factor, and the rCDI rate increased with the number of risk factors (1 risk factor: 31.3%; ≥3 risk factors: 46.1%). Bezlotoxumab reduced rCDI, fecal microbiota transplants, and CDI-associated 30-day readmissions in participants with risk factors for rCDI. Conclusions: The risk factors prespecified in the MODIFY statistical analysis plan are appropriate to identify patients at high risk for rCDI. While participants with ≥3 risk factors had the greatest reduction of rCDI with bezlotoxumab, those with 1 or 2 risk factors may also benefit. Clinical Trials Registration: NCT01241552 (MODIFY I) and NCT01513239 (MODIFY II)

Stress, Coping, Social Support, and Prostate Cancer Risk Among Older African American and Caucasian Men

Objectives: While psychosocial stress and high effort coping have been associated with reduced immune function, no epidemiologic study has addressed psychological stress and risk of prostate cancer. The purpose of this analysis was to investigate the association between stress, coping, social support, and risk of prostate cancer among older men (age 65–79 years). Design: Population-based case-control study in South Carolina. Participants: Cases were 400 incident, histologically confirmed prostate cancer cases identified through the South Carolina Central Cancer Registry between 1999 and 2001 (70.6% response rate). Controls were 385 men identified through the 1999 Health Care Financing Administration Medicare beneficiary file for South Carolina (63.8% response rate). Main Outcome Measures: Consenting participants completed telephone interviews addressing demographics (age, race, income, education, marital status, body mass index), medical and prostate cancer screening history, stress (Global Perceived Stress), coping (John Henryism Scale), and social support. Results: After adjusting for age, race, and South Carolina region, higher John Henryism scores (.24) were modestly associated with prostate cancer risk relative to lower scores (,24) (adjusted odds ratio 1.63, 95% confidence interval 1.11–2.40). This effect is somewhat more pronounced among those perceiving some stress, yet the effect of John Henryism on prostate cancer risk was reduced among those with high levels of social support. Neither higher stress nor social support alone was associated with prostate cancer risk. Conclusions: Higher John Henryism scores indicating high-effort coping may be associated with an increase in prostate cancer risk
