The Terrestrial Residue EXposure (T-REX) model, a spreadsheet-based model developed by the U.S. Environmental Protection Agency (USEPA), is used to estimate the concentrations of pesticides on some representative avian terrestrial food items following a foliar pesticide application. T-REX uses 5 or 6 categories of food items to assess exposure for birds. Different body size classes are used to estimate diet intake levels and to demonstrate different exposures for different size birds with various single component diets. The purpose of this analysis is to determine whether T-REX is a sufficient tool to assess exposure to the majority of threatened and endangered (T&E) bird species in the U.S. based on diets and body sizes of listed species. Our analysis combining diets and body weights of T&E species finds that no listed species weighing less than 50 g consumes primarily plant matter. Therefore, the hypothetical bird included in T-REX weighing 20 g and consuming only short grass that is predicted to have the highest exposure does not represent any T&E bird species. Many T&E species are represented when T-REX considers risk for insectivorous species in the 20-g size class. However, no T&E species that are predominantly insectivorous occur in the larger 100 and 1000-g size classes. Fruit and seed eating T&E species occur in each of the size classes that T-REX considers, so fruit and seed-eating T&E birds are adequately represented in T-REX. T-REX does not include any estimated environmental concentrations (EECs) for aquatic dietary items or nectar, terrestrial vertebrates, soil-dwelling organisms, and non-insect invertebrates (e.g. snails). More than a third of T&E species have diets that are not represented in any of the dietary categories included in T-REX. Slightly more than half the species have diets that include large contributions by dietary items not included in T-REX. An analysis of risk only using T-REX based on simplistic diets is not adequate for a comprehensive assessment of risk from pesticides for all T&E bird species.

OBJECTIVE: The association of anorexia nervosa (AN) with organic brain lesions may offer insight into underlying illness neuropathology. A systematic review reported an association between AN and lesions located in the right frontal lobe. To date, no studies have studied such a case longitudinally. A case of a male presenting with AN and a frontal lobe glioma is described. METHOD: The clinical symptoms and subsequent medical and neuropsychological investigations before and after surgery are reviewed. RESULTS: The remission of ED symptoms is observed at 2 year post-surgery follow up. DISCUSSION: The features of this case are set into the context of recent conceptualizations of AN and the clinical implications for identifying individuals with underlying organic causes. © 2012 by Wiley Periodicals, Inc.

A cross-sectional study of the association between occupational pig exposure and hepatitis E virus (HEV) infection in adult pig farmers and the general population who were not directly exposed to pigs was conducted in Nan Province, Thailand, from November 2010 to April 2011. All participants were interviewed to provide information on their job history, eating habits and other potential confounders. The prevalence of anti-HEV immunoglobulin G antibodies (IgG) among 513 subjects was 23.0%. Hand washing with water and soap was associated with a lower seroprevalence of HEV infection, whereas living in an area with frequent flooding (OR 1.64, 95% CI: 1.00-2.68) and consuming internal pig organs more than twice per week (OR 3.23, 95%CI: 1.15-9.01) were both associated with a higher seroprevalence of anti-HEV IgG. There was no association between HEV seroprevalence and frequent, direct occupational pig contact.
