Diagnosis and Treatment of PTSD and other service-related conditions in the Veteran Patient Population

There are approximately 48,602 veterans living in the state of Vermont with roughly 20% residing in Chittenden County. According to national VA statistics, only 40% of the veteran population receives some health care from the VA. Currently UVM providers receive no formal training in delivering care to veterans and there are no military history templates or PTSD screening tools in PRISM. Giving community providers access to basic VA tools, information and resources will help improve the quality of care they offer to their veteran patients.https://scholarworks.uvm.edu/fmclerk/1067/thumbnail.jp

Who\u27s accessing emergency food services?

Introduction: Last year, Chittenden Emergency Food Shelf provided 1,260,517 pounds of food to over 11,000 people each month via groceries, hot meals and home delivery, supplying an average of almost 40% of food for families. CEFS seeks to improve their services and offerings by better understanding the demographics, food preference, and needs of the clients they serve. Our goal was to collect demographic and utilization data to identify areas where CEFS could enhance services and improve client access to healthful food.https://scholarworks.uvm.edu/comphp_gallery/1208/thumbnail.jp

Monitoring the volatile language of fungi using gas chromatography-ion mobility spectrometry

Fusarium oxysporum is a plant pathogenic fungus leading to severe crop losses in agriculture every year. A sustainable way of combating this pathogen is the application of mycoparasites—fungi parasitizing other fungi. The filamentous fungus Trichoderma atroviride is such a mycoparasite that is able to antagonize phytopathogenic fungi. It is therefore frequently applied as a biological pest control agent in agriculture. Given that volatile metabolites play a crucial role in organismic interactions, the major aim of this study was to establish a method for on-line analysis of headspace microbial volatile organic compounds (MVOCs) during cultivation of different fungi. An ion mobility spectrometer with gas chromatographic pre-separation (GC-IMS) enables almost real-time information of volatile emissions with good selectivity. Here we illustrate the successful use of GC-IMS for monitoring the time- and light-dependent release of MVOCs by F. oxysporum and T. atroviride during axenic and co-cultivation. More than 50 spectral peaks were detected, which could be assigned to 14 volatile compounds with the help of parallel gas chromatography-mass spectrometric (GC-MS) measurements. The majority of identified compounds are alcohols, such as ethanol, 1-propanol, 2-methyl propanol, 2-methyl butanol, 3-methyl-1-butanol and 1-octen-3-ol. In addition to four ketones, namely acetone, 2-pentanone, 2-heptanone, 3-octanone, and 2-octanone; two esters, ethyl acetate and 1-butanol-3-methylacetate; and one aldehyde, 3-methyl butanal, showed characteristic profiles during cultivation depending on axenic or co-cultivation, exposure to light, and fungal species. Interestingly, 2-octanone was produced only in co-cultures of F. oxysporum and T. atroviride, but it was not detected in the headspace of their axenic cultures. The concentrations of the measured volatiles were predominantly in the low ppbv range; however, values above 100 ppbv were detected for several alcohols, including ethanol, 2-methylpropanol, 2-methyl butanol, 1- and 3-methyl butanol, and for the ketone 2-heptanone, depending on the cultivation conditions. Our results highlight that GC-IMS analysis can be used as a valuable analytical tool for identifying specific metabolite patterns for chemotaxonomic and metabolomic applications in near-to-real time and hence easily monitor temporal changes in volatile concentrations that take place in minutes

PTR-MS studies of the reactions of H₃O⁺ with a number of deuterated volatile organic compounds and the subsequent sequential reactions of the primary product ions with water under normal and humid drift tube conditions::implications for use of deuterated compounds for breath analysis

Product ion distributions resulting from the primary reactions of H3O+ with nine D-labeled volatile organic compounds and the subsequent sequential reactions with H2O have been determined using a Proton Transfer Reaction Time of Flight Mass Spectrometer (PTR-TOF 8000 (IONICON Analytik GmbH)) at various reduced electric field (E/N) values ranging from 80 up to 150 Td and for two different absolute humidity levels of air sample < 0.1% and 5%. The specific D-labeled compounds used in this study are acetone-d6, toluene-d8, benzene-d6, ethanol-d (C2H5OD), ethanol-d2 (CH3CD2OH), ethanol-d6, 2-propanol-d8, 2-propanol-d3 (CD3CH(OH)CH3), and isoprene-d5 (CH2CHC(CD2)CD3). With the exception of the two 2-propanol compounds, non-dissociative proton transfer is the dominant primary reaction pathway. For 2-propanol-d8 and 2-propanol-d3 the major primary reaction channel involved is dissociative proton transfer. However, unlike their undeuterated counterparts, the primary product ions undergo subsequent deuterium/hydrogen isotope exchange reactions with the ever present water in the drift tube, the extent of which of course depends on the humidity within that tube. This exchange leads to the generation of various isotopologue product ions, the product ion branching percentages of which are also dependent on the humidity in the drift tube. This results in complex mass spectra and the distribution of product ions leads to issues of reduced sensitivity and accuracy. However, the effect of D/H exchange considerably varies between the compounds under study. In the case of acetone-d6 it is very weak (<1%), because the exchange process is not facile when the deuterium is in the methyl functional group. In comparison, the H3O+/ benzene-d6 (C6D6) reaction and sequential reactions with water result in the production of the isotopologue ions C6Dn(H7-n)+ (where n = 0–6). Changing the value of E/N and/or the humidity in the drift tube considerably affects the amount of the isotope exchange reactions and hence the resulting sequential product ion distributions. An important conclusion of the findings from this work is that care must be taken in the choice of an exogenous deuterated compound for use in breath pharmacokinetic studies using proton transfer reaction mass spectrometry; otherwise the resulting D/H exchange processes impose interpretative problems. © 2018 The Authors.

Representation in Municipal Government

Municipal governments play a vital role in American democracy, as well as in governments around the world. Despite this, little is known about the degree to which cities are responsive to the views of their citizens. In the past, the unavailability of data on the policy preferences of citizens at the municipal level has limited scholars' ability to study the responsiveness of municipal government. We overcome this problem by using recent advances in opinion estimation to measure the mean policy conservatism in every U.S. city and town with a population above 20,000 people. Despite the supposition in the literature that municipal politics are non-ideological, we find that the policies enacted by cities across a range of policy areas correspond with the liberal-conservative positions of their citizens on national policy issues. In addition, we consider the influence of institutions, such as the presence of an elected mayor, the popular initiative, partisan elections, term limits, and at-large elections. Our results show that these institutions have little consistent impact on policy responsiveness in municipal government. These results demonstrate a robust role for citizen policy preferences in determining municipal policy outcomes, but cast doubt on the hypothesis that simple institutional reforms enhance responsiveness in municipal governments
