Groundhog Day in the emergency department: A systematic review of 20 years of news coverage in Australia.

This study examined how the Australian news media have portrayed public hospital Emergency Departments (EDs) over the last two decades. A systematic review and media frame analysis, searching Factiva and Australia and New Zealand News Stream for digital and print news articles published between January 2000 and January 2020. Eligibility criteria were (1) discussed EDs in public hospitals; (2) the primary focus of the article was the ED; (3) focused on the Australian context; (4) were published by one of the Australian state-based news outlets (e.

Integrating human services and criminal justice data with claims data to predict risk of opioid overdose among Medicaid beneficiaries: A machine-learning approach.

Health system data incompletely capture the social risk factors for drug overdose. This study aimed to improve the accuracy of a machine-learning algorithm to predict opioid overdose risk by integrating human services and criminal justice data with health claims data to capture the social determinants of overdose risk. This prognostic study included Medicaid beneficiaries (n = 237,259) in Allegheny County, Pennsylvania enrolled between 2015 and 2018, randomly divided into training, testing, and validation samples.

Direct inhibitors of InhA are active against Mycobacterium tuberculosis.

New chemotherapeutic agents are urgently required to combat the global spread of multidrug-resistant tuberculosis (MDR-TB). The mycobacterial enoyl reductase InhA is one of the few clinically validated targets in tuberculosis drug discovery. We report the identification of a new class of direct InhA inhibitors, the 4-hydroxy-2-pyridones, using phenotypic high-throughput whole-cell screening.

Haloarchaeal gas vesicle nanoparticles displaying Salmonella SopB antigen reduce bacterial burden when administered with live attenuated bacteria.

Innovative vaccines against typhoid and other Salmonella diseases that are safe, effective, and inexpensive are urgently needed. In order to address this need, buoyant, self-adjuvating gas vesicle nanoparticles (GVNPs) from the halophilic archaeon Halobacterium sp. NRC-1 were bioengineered to display the highly conserved Salmonella enterica antigen SopB, a secreted inosine phosphate effector protein injected by pathogenic bacteria during infection into the host cell.

An improved genetic system for bioengineering buoyant gas vesicle nanoparticles from Haloarchaea.

Background: Gas vesicles are hollow, buoyant organelles bounded by a thin and extremely stable protein membrane. They are coded by a cluster of gvp genes in the halophilic archaeon, Halobacterium sp. NRC-1.

Three dialogues concerning robots in elder care.

The three dialogues in this contribution concern 21st century application of life-like robots in the care of older adults. They depict conversations set in the near future, involving a philosopher (Dr Phonius) and a nurse (Dr Myloss) who manages care at a large facility for assisted living. In their first dialogue, the speakers discover that their quite different attitudes towards human-robot interaction parallel fundamental differences separating their respective concepts of consciousness.

Do hospital visitors wash their hands? Assessing the use of alcohol-based hand sanitizer in a hospital lobby.

Background: Reports regarding hand hygiene compliance (HHC) among hospital visitors are limited. Although there is an implicit assumption that the availability of alcohol-based hand sanitizer (AHS) promotes visitor HHC, the degree of AHS use by visitors remains unclear. To assess AHS use, we observed visitor HHC and how it is affected by visual cues in a private university hospital.

The importance of solvent reorganisation in the effect of an ionic liquid on a unimolecular substitution process.

Temperature dependent rate studies demonstrate an enthalpic benefit and an entropic cost associated with the change in the rate of a unimolecular substitution process on addition of a high proportion of an ionic liquid, the latter effect being supported by molecular dynamics simulations.

Using pattern homogenization of binary grayscale masks to fabricate microfluidic structures with 3D topography.

Because fluids at the microscale form three dimensional interfaces and are subject to three dimensional forces, the ability to create microstructures with modulated topography over large areas could greatly improve control over microfluidic phenomena (e.g., capillarity and mass transport) and enable exciting novel microfluidic applications.

Raman spectroscopic monitoring of droplet polymerization in a microfluidic device.

Microfluidic methodologies are becoming increasingly important for rapid formulation and screening of materials, and development of analytical tools for multiple sample screening is a critical step in achieving a combinatorial 'lab on a chip' approach. This work demonstrates the application of Raman spectroscopy for analysis of monomer composition and degree of conversion of methacrylate-based droplets in a microfluidic device. Droplet formation was conducted by flow focusing on the devices, and a gradient of component composition was created by varying the flow rates of the droplet-phase fluids into the microchannels.

The residential competency scale: A new measure of residential functioning skills.

The Residential Competency Scale, an 82-item questionnaire, was developed as a molecular measure for assessing the community living skills of expsychiatric patients in residential care settings. Over the course of its development, normative data were collected on a sample of 251 residents from 24 residential facilities, and critical analyses were performed to examine such aspects as the scale's internal consistency, factorial structure, reliability (both interrater and test-retest), concurrent validity, and discriminant validity. The results were quite favorable and indicate that the Residential Competency Scale is multidimensional, internally consistent, and reliable.
