“Alexa, lock my front door”: An empirical study on factors affecting consumer's satisfaction with VCA‐controlled security devices

alexandrossfakianakis shared this article with you from Inoreader “Alexa, lock my front door”: An empirical study on factors affecting consumer's satisfaction with VCA‐controlled security devices via Psychology & Marketing Abstract Voice conversation agents (VCAs) have moved beyond simple tasks such as information gathering. The integration of VCAs in smart technologies for security has grown in the consumer market. This paper investigates consumers' motivation to use smart technologies controlled by voice conversational agents and how that impacts their perceived hedonic and utilitarian value, which eventually leads to their satisfaction with smart technologies usage. Two cross-sectional studies and a netnography were conducted. The findings showed that the variables measuring technology acceptance mediate the relationship between consumers' motivation and the perceived value of the VCA-controlled smart technologies. Study 1 results show that ease of use and usefulness of the VCA-controlled smart technologies have a more substantial mediating effect between motivation and hedonic value than utilitarian value. For study 2, results show that the mediators had a stronger influence on hedonic and utilitarian va lues for outdoor voice conversational agent-controlled smart technologies than indoor smart technologies. Study 3 showed that smart technologies have both risks and benefits and depend on whether they are being used for themselves or others. The results suggest that marketers need to consider consumer's emphasis on the products' features including its ease of use and usefulness, and strategically complement it with consumers' prevention and promotion focus for each product.

Survey the effect of drug treatment on modulation of cytokines gene expression in Allergic Rhinitis

alexandrossfakianakis shared this article with you from Inoreader Survey the effect of drug treatment on modulation of cytokines gene expression in Allergic Rhinitis via Fundamental & Clinical Pharmacology Abstract Allergic rhinitis as common airway disease has high prevalence in all peoples worldwide. In allergic diseases, Th2 cells release type 2 cytokines which support the inflammation in airways. All the drugs used for allergic rhinitis, do not cure completely, and the choice of drugs according to cost and efficacy is very important in all groups of atopic patients. Therefore, in this study, the effect of commercial drugs on cytokine gene expression has been studied. Male Balb/c mice were divided into six groups. Allergic rhinitis was induced in five of the six groups with ovalbumin, and four of these five groups were treated with salbutamol, budesonide, theophylline and montelukast. The 5th group was used as positive control group and the 6th group as negative control group. For the survey, RNA was extracted, cDNA was synthesized, and quantitative real time PCR was done for 21 genes. The four drugs had different effect on mRNA expression of cytokines (IL-1b, 2, 4, 5, 7, 8, 9, 11, 12, 13 , 17, 18, 22, 25, 31, 33, 37, IFN-γ, TNF-α, TGF-β1 and Eotaxin) in the allergic rhinitis groups. Salbutamol can be used during pregnancy and breastfeeding, but it has some side effects. Budesonide in the inhaled form is generally safe in pregnancy. Theophylline cannot control allergic attack in the long run. Montelukast is not useful in the treatment of acute. Immunomodulatory and anti-inflammatory effects of drugs in control of allergic rhinitis via Th2 cytokines can be new approaches in molecular medicine. View on Web

Accessibility of Level III trauma centers for underserved populations: A cross-sectional study

alexandrossfakianakis shared this article with you from Inoreader Accessibility of Level III trauma centers for underserved populations: A cross-sectional study via Journal of Trauma and Acute Care Surgery - Current Issue BACKGROUND By providing definitive care for many, and rapid assessment, resuscitation, stabilization, and transfer to Level I/II centers when needed, Level III trauma centers can augment capacity in high resource regions and extend the geographic reach to lower resource regions. We sought to (1) characterize populations served principally by Level III trauma centers, (2) estimate differences in time to care by trauma center level, and (3) update national estimates of trauma center access. METHODS In a cross-sectional study (United States, 2019), we estimated travel time from census block groups to the nearest Level I/II trauma center and nearest Level III trauma center. Block groups were categorized based on the level of care accessible within 60 minutes, then distributions of population characteristics and differences in time to care were estimated. RESULTS An estimated 22.8% of the US population (N = 76,119,228) lacked access to any level of trauma center care within 60 minutes, and 8.8% (N = 29,422,523) were principally served by Level III centers. Black and American Indian/Alaska Native (AIAN) populations were disproportionately represented among those principally served by Level III centers (39.1% and 12.2%, respectively). White and AIAN populations were disproportionately represented among those without access to any trauma center care (26.2% and 40.8%, respectively). Time to Level III care was shorter than Level I/II for 27.9% of the population, with a mean reduction in time to care of 28.9 minutes (SD = 31.4). CONCLUSION Level III trauma centers are a potential source of trauma care for underserved populations. While Black and AIAN disproportionately rely on Level III centers for care, most with access to Level III centers also have access to Level I/II centers. The proportion of the US population with timely access to trauma care has not improved since 2010. LEVEL OF EVIDENCE Prognostic/Epidemiological; Level IV. View on Web

Postinjury platelet aggregation and venous thromboembolism

alexandrossfakianakis shared this article with you from Inoreader Postinjury platelet aggregation and venous thromboembolism via Journal of Trauma and Acute Care Surgery - Current Issue BACKGROUND Posttraumatic venous thromboembolism (VTE) remains prevalent in severely injured patients despite chemoprophylaxis. Importantly, although platelets are central to thrombosis, they are not routinely targeted in prevention of posttraumatic VTE. Furthermore, platelets from injured patients show ex vivo evidence of increased activation yet impaired aggregation, consistent with functional exhaustion. However, the relationship of this platelet functional phenotype with development of posttraumatic VTE is unknown. We hypothesized that, following injury, impaired ex vivo platelet aggregation (PA) is associated with the development of posttraumatic VTE. METHODS We performed a secondary analysis of 133 severely injured patients from a prospective observational study investigating coagulation and inflammation (2011–2019). Platelet aggregation in response to stimulation with adenosine diphosphate (ADP), collagen, and thrombin was measured at presentation (preresuscitation) and 24 hours (postresuscitation). Viscoelastic clot strength and lysis were measured in parallel by thromboelastography. Multivariable regression examined relationships between PA at presentation, 24 hours, and the change (δ) in PA between presentation and 24 hours with development of VTE. RESULTS The 133 patients were severely injured (median Injury Severity Score, 25), and 14% developed VTE (all >48 hours after admission). At presentation, platelet count and PA were not significantly different between those with and without incident VTE. However, at 24 hours, those who subsequently developed VTE had significantly lower platelet counts (126 × 109/L vs. 164 × 109/L, p = 0.01) and lower PA in response to ADP (p View on Web

New perspectives for prosthetic valve endocarditis - impact of molecular imaging by FISHseq diagnostics

alexandrossfakianakis shared this article with you from Inoreader New perspectives for prosthetic valve endocarditis - impact of molecular imaging by FISHseq diagnostics via Clinical Infectious Diseases Advance Access Abstract BackgroundThe causative microbial etiology of prosthetic valve infective endocarditis (PVE) can be difficult to identify. Our aim was to investigate the benefit of the molecular imaging technique fluorescence in situ hybridization (FISH) combined with 16S rRNA-gene PCR and sequencing (FISHseq) for the analysis of infected prosthetic heart valves. Methods We retrospectively evaluated the diagnostic outcome of 113 prosthetic valves from 105 patients with suspected PVE, treated in the years 2003-2013 in the Department of Cardiac Surgery, Charité University Medicine Berlin. Each prosthetic valve underwent cultural diagnostics and was routinely examined by FISH combined with 16S rRNA-gene PCR and sequencing. We compared classical microbiological culture outcomes (blood and valve cultures) with FISHseq results and evaluated the diagnostic impact of the molecular imaging technique. Results Conventional microbiological diagnostic alone turned out to be insufficient, as 67% of p reoperative blood cultures were non-informative (negative, inconclusive or not obtained) and 67% valve cultures remained negative. FISHseq improved the conventional cultural diagnostic methods in PVE in 30% of the cases and increased diagnostic accuracy. Out of the valve culture-negative PVE cases, FISHseq succeeded to identify the causative pathogen in 35%. Conclusions FISHseq improves PVE diagnostics, complementing the conventional cultural methods. In addition to species identification, FISH provides information about the severity of PVE and state of the pathogens, e.g. stage of biofilm formation, activity and localization on and within the prosthetic material. As a molecular imaging technique, FISHseq enables the unambiguous discrimination of skin flora as contaminant or infectious agent. View on Web
