Understanding The Consumption Of Antimicrobial Resistance–Related Content On Social Media: Twitter Analysis, Hyunuk Kim, Chris R. Proctor, Dylan Walker, Ronan R. Mccarthy

Business Faculty Articles and Research

Background: Antimicrobial resistance (AMR) is one of the most pressing concerns in our society. Today, social media can function as an important channel to disseminate information about AMR. The way in which this information is engaged with depends on a number of factors, including the target audience and the content of the social media post.

Objective: The aim of this study is to better understand how AMR-related content is consumed on the social media platform Twitter and to understand some of the drivers of engagement. This is essential to designing effective public health strategies, raising awareness about antimicrobial …

Plasma-Treated Water Affects Listeria Monocytogenes Vitality And Biofilm Structure, Oliver Handorf, Viktoria Isabella Pauker, Thomas Weihe, Uta Schnabel, Eric Freund, Sander Bekeschus, Katharina Riedel, Jörg Ehlbeck

Articles

Plasma-generated compounds (PGCs) such as plasma-processed air (PPA) or plasma-treated water (PTW) offer an increasingly important alternative for the treatment of microorganisms in hard-to-reach areas found in several industrial applications including the food industry. To this end, we studied the antimicrobial capacity of plasma-treated water on the vitality and biolm formation of Listeria monocytogenes, a common food spoilage microorganism. Using a microwave plasma (MidiPLexc), 10 ml of deionized water was treated for 100 s, 300 s and 900 s (pretreatment time) and the bacterial biolm was subsequently exposed to the PTW for 1 min, 3 min and 5 min (posttreatment …

Net Return Distributions When Metaphylaxis Is Used To Control Bovine Respiratory Disease In High Health-Risk Cattle, Elliott James Dennis, Ted C. Schroeder, David G. Renter

Department of Agricultural Economics: Faculty Publications

This study’s objective was to estimate net returns and return risk for antimicrobial metaphylaxis options to manage bovine respiratory disease (BRD) in high health-risk feedlot cattle. The effectiveness of antimicrobials for metaphylaxis varies by cattle population. How differing antimicrobial effectiveness translates to net return profitability for heterogeneous cattle populations is less understood. Net returns and return risk were assessed using a net return simulation model adapted to allow for heterogeneity in high health-risk cattle placement characteristics and antimicrobial choice to control BRD. The net return model incorporated how antimicrobials modify BRD health and performance outcomes. Health and performance outcomes were …

Nurses Are Underutilised In Antimicrobial Stewardship E Results Of A Multisite Survey In Paediatric And Adult Hospitals, Mona Mostaghim, Thomas Snelling, Brendan J. Mcmullan, Pamela Konecny, Stuart Bond, Suman Adhikari, Adriana J. Chubaty, Cathy Lovell, Beata Bajorek

Faculty of Science, Medicine and Health - Papers: part A

Objectives: Explore perceptions and attitudes of nurses in regard to antimicrobial stewardship (AMS), their roles as nurses, and identify differences in perceptions and attitudes across paediatric and adult settings. Methods: Electronic survey administered to nursing staff across three public Australian tertiary institutions with AMS facilitated by a shared electronic approval and decision support system. Results: Overall 65% (93/142) of nurses who completed the survey were familiar with the term AMS, and 75% recognised that they were expected to have a role alongside other disciplines, including ward pharmacists (paediatric 88%, adult 73%; p = 0.03). Hand hygiene and infection control (86%), …

Dr. Who?: The Science And Culture Of Medical Wear Design, Patricia Duignan

Theses and Dissertations

The multi-million-dollar medical uniform industry has not utilized advancements in garment and textile technology that could positively impact the protection of healthcare professionals and patients. In most cases the uniforms meet basic requirements – they clothe the professional in a recognizable way. Little innovation in design, function and performance, has been applied to these garments. This is particularly evident in the case of the stereotypical white lab coat worn by many physicians, despite evidence indicating that these lab coats may carry contamination and play a role in the spread of deadly bacteria. Healthcare Associated Infections (HAIs) are among the most …

Antimicrobial, Antimalarial And Cytoxicity Activities Of Constituents Of A Bhutanese Variety Of Ajania Nubigena, Phurpa Wangchuk, Paul A. Keller, Stephen G. Pyne, Jurgen Korth, - Samten, Malai Taweechotipatr, Roonglawan Rattanajak, Sumalee Kamchonwongpaisan

Faculty of Science, Medicine and Health - Papers: part A

An investigation of the essential oil (EO) and the crude MeOH extract of a Bhutanese variety of Ajania nubigena using GC/GC-MS and NMR found the following: a) one kg of the dried plant material contained 0.7% w/w EO; b) 44 of the 53 GC-FID peaks of the EO were identified with (3R,6R)-linalool oxide acetate (75.8 %) as the major constituent (chemotype II) and chamazulene as a new sub-chemotype; c) purification of the EO furnished (3R,6R)-linalool oxide acetate (1), chamazulene (2), (E)-2-(2,4-hexadiynylidene)-1,6-dioxaspiro[4,4]non-3-ene (3), and (Z)-2-(2,4-hexadinylidene)-1,6-dioxaspiro[4,4]non-3-ene (4); d) from the crude MeOH extract, four flavonoid compounds: 1-(4-hydroxyphenyl)propan-1-one (5), oxyanin B (6), luteolin …

Antimalarial, Anticancer, Antimicrobial Activities And Chemical Constituents Of Essential Oil From The Aerial Parts Of Cyperus Kyllingia Endl, Stephen G. Pyne, Boonsom Liawruangrath, Saisunee Liawruangrath, M Garson, S Khamsan, A Teerawutkulrag

Faculty of Science - Papers (Archive)

The chemical constituents of the essential oil from Cyperus kyllingia Endl. were analyzed by a GC, GC-MS. Twenty-three compounds were identified, accounting for 93.75% of the total oil that consisted mainly of oxygenated sesquiterpenes (53.52%), particularly sesquiterpene hydrocarbons (38.97%), and carboxylic acid (1.26%). The most representative compounds were -cadinol (19.32%), caryophyllene oxide (12.17%), -muurolol (11.58%), -humulene (9.85%), and -atlantone (6.07%). The oil showed significant activities against Plasmodium falcipalum (K1, multi drug resistant strain) and NCI-H187 (Small Cell Lung Cancer) with the IC50 values of 7.52 and 7.72 g/mL, respectively. The oil exhibited highly active against Staphylococcus aureus ATCC25923 and moderately …
