Information Systems and Health Care-II: Back to the Future with RFID: Lessons Learned - Some Old, Some New

Healthcare facilities face limited resources and expanding expenses. Emerging information technologies offer a means for healthcare to measure and control their resources and workflow processes, and ultimately improve patient care. The usefulness of one emerging information technology, Radio Frequency Identification (RFID), is examined in a proof of application study conducted at a Level-1 trauma unit. Results from the study suggest not only that RFID technology can assist in the measurement and ultimate control of workflow processes, but also that traditional and non-traditional IS practices are necessary for successful RFID implementation. Lessons learned about the idiosyncrasies of RFID implementation and the cleansing and analysis of RFID-generated data are reported

Exploring the Effects of Non-traditional Narrative Video Ads on Tourism Intentions Among Viewers with and without Previous Destination Experience.

Tourism is a storying and narrative experience that weaves multiple accounts about travel destinations, sites, and people into consumer expectations and perceptions of what is authentic in a travel experience (Chronis 2012a, Moscardo 2010, Bruner 2005). Story-telling narratives use the natural link of human experience often shared with others (Zhong et al. 2017, Mossberg 2008, McCabe and Foster 2006) and have become a helpful communication tool for understanding and promoting tourism (Zhong, Yun, Busser, and Baloglu 2017). Story-telling narration provides a valuable framework in which the destination is portrayed as believable and authentic to potential tourists (Kim and Yuon 2017). Our research has two main objectives: 1.) to explore the influence of narrative video advertisements on perceptions of authenticity, and 2.) to determine the role of individual differences and their effects on perceptions of authenticity. Our study\u27s two ads were specifically designed to feature attributes not commonly part of the City\u27s authentic historical appeal. As such, the focus of the ads could be perceived as less authentic by the viewer. We examine the role of narrative story-telling in shaping positive perceptions of authenticity for advertisements that explore non-traditional tourism appeals. We further explore how the viewer\u27s prior visits to the Cityinfluence perceptions of authenticity and subsequent ad effectiveness. The promotion of non-historic features was designed to influence repeat visits with something new to experience and potential visitors who might be more interested in non-historic experiences. Previous visitors might not be open to stories related to activities that were not necessarily related to their previous visits and find the ad less authentic but still respond to new experiences\u27 potential

Characterization of Shewanella oneidensis MtrC: a cell-surface decaheme cytochrome involved in respiratory electron transport to extracellular electron acceptors

MtrC is a decaheme c-type cytochrome associated with the outer cell membrane of Fe(III)-respiring species of the Shewanella genus. It is proposed to play a role in anaerobic respiration by mediating electron transfer to extracellular mineral oxides that can serve as terminal electron acceptors. The present work presents the first spectropotentiometric and voltammetric characterization of MtrC, using protein purified from Shewanella oneidensis MR-1. Potentiometric titrations, monitored by UV–vis absorption and electron paramagnetic resonance (EPR) spectroscopy, reveal that the hemes within MtrC titrate over a broad potential range spanning between approximately +100 and approximately -500 mV (vs. the standard hydrogen electrode). Across this potential window the UV–vis absorption spectra are characteristic of low-spin c-type hemes and the EPR spectra reveal broad, complex features that suggest the presence of magnetically spin-coupled low-spin c-hemes. Non-catalytic protein film voltammetry of MtrC demonstrates reversible electrochemistry over a potential window similar to that disclosed spectroscopically. The voltammetry also allows definition of kinetic properties of MtrC in direct electron exchange with a solid electrode surface and during reduction of a model Fe(III) substrate. Taken together, the data provide quantitative information on the potential domain in which MtrC can operate

INTERVAL (investigation of NICE technologies for enabling risk-variable-adjusted-length) dental recalls trial: a multicentre randomised controlled trial investigating the best dental recall interval for optimum, cost-effective maintenance of oral health in dentate adults attending dental primary care

Background Traditionally, patients at low risk and high risk of developing dental disease have been encouraged to attend dental recall appointments at regular intervals of six months between appointments. The lack of evidence for the effect that different recall intervals between dental check-ups have on patient outcomes, provider workload and healthcare costs is causing considerable uncertainty for the profession and patients, despite the publication of the NICE Guideline on dental recall. The need for primary research has been highlighted in the Health Technology Assessment Group’s systematic review of routine dental check-ups, which found little evidence to support or refute the practice of encouraging 6-monthly dental check-ups in adults. The more recent Cochrane review on recall interval concluded there was insufficient evidence to draw any conclusions regarding the potential beneficial or harmful effects of altering the recall interval between dental check-ups. There is therefore an urgent need to assess the relative effectiveness and cost-benefit of different dental recall intervals in a robust, sufficiently powered randomised control trial (RCT) in primary dental care. Methods This is a four year multi-centre, parallel-group, randomised controlled trial with blinded outcome assessment based in dental primary care in the UK. Practitioners will recruit 2372 dentate adult patients. Patient participants will be randomised to one of three groups: fixed-period six month recall, risk-based recall, or fixed-period twenty-four month recall. Outcome data will be assessed through clinical examination, patient questionnaires and NHS databases. The primary outcomes measure gingival inflammation/bleeding on probing and oral health-related quality of life. Discussion INTERVAL will provide evidence for the most clinically-effective and cost-beneficial recall interval for maintaining optimum oral health in dentate adults attending general dental practice

Obesity dysregulates the pulmonary antiviral immune response

Obesity is a well-recognized risk factor for severe influenza infections but the mechanisms underlying susceptibility are poorly understood. Here, we identify that obese individuals have deficient pulmonary antiviral immune responses in bronchoalveolar lavage cells but not in bronchial epithelial cells or peripheral blood dendritic cells. We show that the obese human airway metabolome is perturbed with associated increases in the airway concentrations of the adipokine leptin which correlated negatively with the magnitude of ex vivo antiviral responses. Exogenous pulmonary leptin administration in mice directly impaired antiviral type I interferon responses in vivo and ex vivo in cultured airway macrophages. Obese individuals hospitalised with influenza showed dysregulated upper airway immune responses. These studies provide insight into mechanisms driving propensity to severe influenza infections in obesity and raise the potential for development of leptin manipulation or interferon administration as novel strategies for conferring protection from severe infections in obese higher risk individuals
