News GUAM From: Cherie Walth SWCA Environmental Consultants, Albuquerque, New Mexico, USA Email: [email protected] Subject: Brief Discussion of the Results from the Agana Bridge Project, Guam The Agana Bridge project for the Department of Public Works, Guam, is located along Route 1 from the intersection of Route 4 eastward to the intersection of Route 8, and south along Route 8 for 120 m (394 feet). The study area has been extensively disturbed in historic to modern times, with WWII bombing, channelization of the Agana River, construction of Route 1/Route 8, and the installation of utilities along the roadway. Despite the extensive past disturbance that had impacted the cultural deposits in the area, the project area still retains undisturbed cultural deposits. Fieldwork commenced June 28, 2012, and ended on April 11, 2014. The nearly 2 years of fieldwork included monitoring of ground disturbance below the base course of the roadway, hand excavation of four control units, excavation of 19 non-burial features, and excavation of 65 field-identified human burials.

This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. The genera Actinobacillus, Haemophilus, and Pasteurella exhibit extensive polyphyletic branching in phylogenetic trees and do not represent coherent clusters of species. In this study, we have utilized molecular signatures identified through comparative genomic analyses in conjunction with genome based and multilocus sequence based phylogenetic analyses to clarify the phylogenetic and taxonomic boundary of these genera. We have identified large clusters of Actinobacillus, Haemophilus, and Pasteurella species which represent the “sensu stricto” members of these genera. We have identified 3, 7, and 6 conserved signature indels (CSIs), which are specifically shared by sensu stricto members of Actinobacillus, Haemophilus, and Pasteurella, respectively. We have also identified two different sets of CSIs that are unique characteristics of the pathogen containing genera Aggregatibacter and Mannheimia, respectively. It is now possible to demarcate the genera Actinobacillus sensu stricto, Haemophilus sensu stricto, and Pasteurella sensu stricto on the basis of discrete molecular signatures.

  • What Is the Relationship Between Alcohol Consumption and All- Cause Mortality?: Systematic Review Protocol
    DRAFT - Current as of 4/20/2020 WHAT IS THE RELATIONSHIP BETWEEN ALCOHOL CONSUMPTION AND ALL- CAUSE MORTALITY?: SYSTEMATIC REVIEW PROTOCOL This document describes the protocol for a systematic review to answer the following question: What is the relationship between alcohol consumption and all-cause mortality? The 2020 Dietary Guidelines Advisory Committee, Beverages and Added Sugars Subcommittee, answered this question by conducting a systematic review with support from USDA’s Nutrition Evidence Systematic Review (NESR). NESR methodology for answering a systematic review question involves: • searching for and selecting articles, • extracting data and assessing the risk of bias of results from each included article, • synthesizing the evidence, • developing a conclusion statement, • grading the evidence underlying the conclusion statement, and • recommending future research. More information about NESR’s systematic review methodology is available on the NESR website: https://nesr.usda.gov/2020-dietary-guidelines-advisory-committee-systematic-reviews. This protocol is up-to-date as of: 4/20/2020. This document reflects the protocol as it was implemented. It now includes the electronic databases and search terms, and literature search and screening results, including a list of included articles, and a list of excluded articles with the rationale for exclusion.
