BACKGROUND: Adverse medical events (AMEs) pose serious threats to patient safety. One of the major challenges of AME reporting is low physician engagement. This study attempted to examine how punishment and reward can improve physicians' AME reporting in China. METHODS: A survey was conducted in a large hospital with 1693 beds in China. Data were collected from 311 physicians. Ordinal and binary logistic regression was used for data analysis. RESULTS: This study reveals that both punishment and reward are positively associated with intention to report AMEs...

Azar Farjamnia, Bret Jackson
A quantum approach based on an expansion in vibrationally adiabatic eigenstates is used to explore the dissociative chemisorption of CO2 on Ni(100). The largest barrier to reaction corresponds to the formation of a bent anionic molecular precursor, bound to the surface by about 0.24 eV. The barrier to dissociation from this state is small. Our computed dissociative sticking probabilities on Ni(100) for molecules in the ground state are in very good agreement with available experimental data, reasonably reproducing the variation in reactivity with collision energy...

This paper presents an elastic ribbon-like piezoelectric energy harvester which is targeted for skin-wearable devices by harnessing the movements of stretchable surfaces. The device aims to power up smart thin stick-on devices for healthcare monitoring. By embedding a ribbon-like PVDF film in a flexible elastomer, Ecoflex, the device is potentially able to stretch 34%, while maintaining internal strain of the film below its plastic deformation limit. Alternate electrode layout and bimorph configuration help to reduce charge cancellation, while increasing overall effectiveness...

Heart rate variability analysis is a promising method for measuring pain in premature infants. The Lomb algorithm was adapted and compared with fast Fourier transform (FFT) for the purposes of PSD estimation. Both FFT and the Lomb algorithm had similar low frequency (LF) estimation error rates. However, the Lomb algorithm had a significant smaller error rate than FFT when estimating high frequency (HF). In addition, the ECG signals of two premature infants in the newborn intensive care unit were analyzed while undergoing a routine heel stick, a common painful procedure...

Computer vision assisted diagnostic systems are gaining popularity in different healthcare applications. This paper presents a video analysis and pattern recognition framework for the automatic grading of vertical suspension tests on infants during the Hammersmith Infant Neurological Examination (HINE). The proposed vision-guided pipeline applies a color-based skin region segmentation procedure followed by the localization of body parts before feature extraction and classification. After constrained localization of lower body parts, a stick-diagram representation is used for extracting novel features that correspond to the motion dynamic characteristics of the infant's leg movements during HINE...

Bo Cai, Dipankar Bandyopadhyay
A normality assumption is typically adopted for the random effects in a clustered or longitudinal data analysis using a linear mixed model. However, such an assumption is not always realistic, and it may lead to potential biases of the estimates, especially when variable selection is taken into account. Furthermore, flexibility of nonparametric assumptions (e.g., Dirichlet process) on these random effects may potentially cause centering problems, leading to difficulty of interpretation of fixed effects and variable selection...

In-situ forming implants (ISFI) offer an interesting potential for the treatment of periodontitis, allowing for time-controlled drug release directly at the site of action (which is difficult to reach). For this purpose, ISFI loaded with antibiotics have been reported in the literature. But the use of antibiotic drugs at low doses over prolonged periods of time can lead to the development of bacterial resistances. This risk should be avoided. The aim of this study was to develop a novel type of in-situ forming implants, loaded with the antiseptic drug chlorhexidine...

The current study investigated individual differences in the flexibility of peripersonal space (i.e., representational space near the body), specifically in relation to trait claustrophobic fear (i.e., fear of suffocating or being physically restricted). Participants completed a line bisection task with either a laser pointer (Laser condition), allowing for a baseline measure of the size of one's peripersonal space, or a stick (Stick condition), which produces expansion of one's peripersonal space. Our results revealed that individuals high in claustrophobic fear had larger peripersonal spaces than those lower in claustrophobic fear, replicating previous research...

Ice cream, a popular product worldwide, is usually a milk-based product with other types of ingredients (fruit, eggs, cocoa, dried fruit, additives, and others). Different materials are used to obtain the desired taste, texture, consistency, and appearance of the final product. This study surveyed ice cream products available in Italy for heavy metals (lead, cadmium, chromium, tin, and arsenic). The differences between artisanal and industrial ice cream were also investigated because of the importance in the Italian diet and the diffusion of this ready-to-eat food...
