“…A mobile nursing app in nursing services is still in its infancy. Previous studies mainly focus on the construction of a mobile nursing app [9,10], the investigation of application needs [11,12] and the exploration of the feasibility of nursing [13][14][15]. A mobile nursing app has the characteristics by the use of mobile applications, such as the emphasis on the individual's smart phone use ability [16], and the ability to accept mobile applications [17], which puts forward higher requirements for nurses.…”

Background Although a mobile nursing application has began to adopt in nursing, few studies have focused on nurses’ behavioral intention of it. The objective of this study is to gain insight into the behavioral intention of nurses, i.e. chinese nurses of the future, to use a mobile nursing application. This study adopted an extension of the Unified Theory of Acceptance and Use of Technology to examine Chinese nurses’ acceptance of a mobile nursing application. Methods A total of 1207 nurses participated in the cross-sectional survey. The majority of nurses were female (96.2%). The mean age of the participants was 34.18 (SD 7.39). The hypothesized relationships were tested using AMOS structural equation model. Results All constructs exhibited an acceptable level of reliability and validity with Cα and CR > 0.7 and AVE > 0.5. An extension of the Unified Theory of Acceptance and Use of Technology Model had good explanatory power for nurses’ behavioral intention of a mobile nursing application. Although effort expectancy and perceived risks had a surprisingly insignificant effect on nurses’ behavioral intention to use a mobile nursing application, performance expectancy, social influence, facilitating conditions, self-efficacy, and perceived incentives demonstrated significant influence with β = .259, p < .001, β = .296, p < .001, β = .063, p = .037, β = .344, p < .001, β = .091, p = .001, respectively. Conclusion With 70.2% of the variance in behavioral intention to use a mobile nursing app explained by this model, it could be helpful for potential adopters, and further investigation should test the actual usage behavior for a mobile nursing app and investigate the related factors.

“…[30][31][32] Existing models frequently overestimate %TBSA burn, begetting excessive fluid resuscitation and inappropriate referrals. 14,[31][32][33][34] Existing models' estimates are particularly erroneous for patients with obesity, who experience higher rates of morbidity and mortality after burn injury. 9,10, [35][36][37][38] With nearly half of all US adults projected to be obese by 2030, 39 a one-size-fits-all model for estimating %TBSA burn is inadequate.…”

Practical Computer Vision Application to Compute Total Body Surface Area Burn

IMPORTANCECritical burn management decisions rely on accurate percent total body surface area (%TBSA) burn estimation. Existing %TBSA burn estimation models (eg, Lund-Browder chart and rule of nines) were derived from a linear formula and a limited number of individuals a century ago and do not reflect the range of body habitus of the modern population.OBJECTIVE To develop a practical %TBSA burn estimation tool that accounts for exact burn injury pattern, sex, and body habitus. DESIGN, SETTING, AND PARTICIPANTSThis population-based cohort study evaluated the efficacy of a computer vision algorithm application in processing an adult laser body scan data set. High-resolution surface anthropometry laser body scans of 3047 North American and European adults aged 18 to 65 years from the Civilian American and European Surface Anthropometry Resource data set (1998)(1999)(2000)(2001) were included. Of these, 1517 participants (49.8%) were male. Race and ethnicity data were not available for analysis. Analyses were conducted in 2020. MAIN OUTCOMES AND MEASURESThe contributory %TBSA for 18 body regions in each individual. Mobile application for real-time %TBSA burn computation based on sex, habitus, and exact burn injury pattern. RESULTSOf the 3047 individuals aged 18 to 65 years for whom body scans were available, 1517 (49.8%) were male. Wide individual variability was found in the extent to which major body regions contributed to %TBSA, especially in the torso and legs. Anterior torso %TBSA increased with increasing body habitus (mean [SD], 15.1 [0.9] to 19.1 [2.0] for male individuals; 15.1 [0.8] to 18.0 [1.7] for female individuals). This increase was attributable to increase in abdomen %TBSA (mean [SD], 5.3 [0.7] to 8.7 [1.8]) among male individuals and increase in abdomen (mean [SD], 4.6 [0.6] to 6.8 [1.7]) and pelvis (mean [SD], 1.5 [0.2] to 2.9 [0.9]) %TBSAs among female individuals. For most body regions, Lund-Browder chart and rule of nines estimates fell outside the population's measured interquartile ranges. The mobile application tested in this study, Burn Area, facilitated accurate %TBSA burn computation based on exact burn injury pattern for 10 sex and body habitus-specific models.CONCLUSIONS AND RELEVANCE Computer vision algorithm application to a large laser body scan data set may provide a practical tool that facilitates accurate %TBSA burn computation in the modern era.

“…The severity of burn trauma is represented by the burn depth and burn size. Burn size can be estimated by reference to the total body surface area (TBSA) using several methods [palms rule (16), nines rule (16), Lund and Browder chart (17), and mobile applications (17)]. Inclusion criteria included thermal burns with a TBSA affected by the burn <25% and patients over 18 years of age.…”

Clinical significance of serum matrix metalloproteinase 9 and tissue inhibitor of metalloproteinase 1 in the first phase of burn trauma evolution

No prospective study has specifically examined the serum levels of matrix metalloproteinase-9 (MMP-9) and tissue inhibitor of metalloproteinase-1 (TIMP-1) in the early shock phase of burn-injured patients. Thus, we aimed to detect early changes, activity dynamics, and the predictive value of MMP-9, TIMP-1, and the MMP-9/TIMP-1 ratio to better understand the early repair mechanisms for the development of future therapies for patients with thermal burns. Twenty-five patients with a total body surface area (TBSA) affected by burn <25%, and 30 healthy subjects were enrolled in the study. Serum levels of MMP-9 and TIMP-1 were determined by the ELISA method. Our results showed that MMP-9 concentrations increased immediately after injury and remained on a plateau. In contrast, TIMP-1 showed an upward trend throughout the 7-day study period, and the time course of the MMP-9/TIMP-1 ratio followed the inverse dynamics of TIMP-1. Analysis of the areas under the receiver operating characteristic (ROC) curves (AUC) showed that patients with burn wounds tended to have a MMP-9 value higher than 421.5 ng/ml (AUC= 0.979), TIMP-1 value higher than 231.6 ng/ml (AUC= 0.908), and MMP-9/TIMP-1 ratio higher than 2.31 (AUC= 0.959) (P<0.001). Our findings suggest that although the variations in the two biomarkers were different regarding the time of the initial insult, their ratio is a specific and sensitive indicator of burn evolutivity in patients with a TBSA affected by a burn <25%.
