A better understanding of the underlying factors that influence the causes of fire scene injuries can improve firefighters' safety.ObjectiveFor this reason, the study aimed to determine the importance of Smart Personal Protective Equipment and wearable technology in protecting the health and safety of firefighters by using them instead of traditional equipment and systems. According to expert opinions and literature reviews, the dangers faced by firefighters have been determined to be thermal, physical, biological, environmental, and chemical.MethodsAnalytical Hierarchy Process (AHP) and Preference Ranking Organization Method for Enrichment Evaluations (PROMETHEE) methods were used in the study. The AHP method was preferred because it is a systematic decision-making method that includes both ranking and comparison techniques. The PROMETHEE method was preferred because it provides the opportunity to make effective decisions in a very short time by basing the decision-making process on a scientific basis. In addition to the graphical representation of the ranking of alternatives, it offers decision-makers the opportunity to make various statistical analyses.ResultsThe weights of the hazards were calculated using the AHP method. Physical hazards accounted for the highest weight. PROMETHEE was used in the ranking of wearable smart technological products to protect the health and safety of firefighters.<b>Conclusions:</b> Products are listed as Personal Protection System, PROeTEX PPE, Wearable IoT Device, Flame Resistant Shirt, Fall Detection Systems, Smart Wearable Underwear, and WASP. With the study, it was concluded that the risk of firefighters being trapped would play an essential role in the prevention of death and injury.

However, the use of this device can cause myocardial injury due to multiple insertions of various catheters.ObjectiveTherefore, this study aimed to evaluate the hemodynamic performance of a newly developed double-lumen catheter (DLC) for LVAD.MethodsTwo different LVAD DLC prototypes (a semi-circular and a concentric catheter) were designed based on the structure of venous DLC. Computational fluid dynamics (CFD) simulations were performed using the finite element method. The CFD results were confirmed through the testing of the 31 Fr prototype. The aorta is a large vessel with shear rates up to >300 s<sup>-1</sup> and we used a reasonable approximation to model blood as a Newtonian fluid.ResultsAt a flow rate of 5 L/min, the semi-circular prototype achieved an infusion pressure of 74.68 mmHg, while the concentric prototype achieved an infusion pressure of 46.11 mmHg. The CFD results matched the experimental results with a mean percentage error of less than 7%. The peak wall shear stress in the semi-circular prototype (717.5 Pa) was higher than the hemolysis threshold (400 Pa), which could cause blood damage, and it also had a higher hemolysis index compared to concentric prototype. Moreover, both prototypes exhibited areas of blood stagnation and recirculation, suggesting a possible risk of thrombosis.ConclusionBoth prototypes of the LVAD DLC demonstrated similar blood flow rates. The semi-circular prototype showed superior infusion pressure compared to the concentric prototype, but had poorer hemolysis performance. However, the potential risk of thrombosis for both still exists.

Positive end-expiratory pressure (PEEP) is essential in mechanical ventilation to enhance oxygenation, yet its application may elevate intracranial pressure (ICP).

Patients were divided into high PEEP (> 10cmH2O) and low to moderate PEEP (5-10cmH2O) groups. Parameters including PaO2, PaCO2, PaO2/FiO2, driving pressure, compliance (Cst), airway resistance, such as heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), central venous pressure (CVP), cardiac index (CI), ICP, and cerebral perfusion pressure (CPP) were recorded pre- and post-ventilation initiation, with correlation analysis performed between ICP and other parameters.ResultsPre-treatment comparisons between the high PEEP and low to moderate PEEP groups revealed no significant differences in PaO2, PaCO2, PaO2/FiO2, driving pressure, Cs, and airway resistance. However, post-treatment analysis showed significant disparities, with the high PEEP group exhibiting higher PaO2 and PaO2/FiO2 levels and lower PaCO2, driving pressure, and airway resistance levels compared to the low to moderate PEEP group. Additionally, hemodynamic parameters such as HR, SBP, DBP, CI, MAP, CVP, ICP, and CPP remained more stable in the low to moderate PEEP group post-treatment, with ICP demonstrating significant correlations with various physiological parameters.ConclusionHigh PEEP improves oxygenation and respiratory mechanics in acute neurological injury patients on mechanical ventilation but may affect hemodynamic parameters, ICP, and CPP.

Patients were divided into a standard intervention group and an early nutritional intervention and counseling group. Baseline characteristics, muscle mass parameters, quality of life assessments, nutritional parameters, and adverse events were compared between the two groups.ResultsThe baseline characteristics of the study participants were well-balanced between the two groups. The early nutrition intervention group demonstrated significant improvements in muscle mass parameters, including grip strength, skeletal muscle mass, muscle strength, calf circumference, and handgrip measurement, compared to the standard intervention group. Additionally, the early nutrition intervention group showed significant enhancements in several aspects of quality of life, including physical functioning, mental health, energy/fatigue, and general health scores.

Because many medical domain datasets are class imbalanced, data resampling methods, including oversampling, undersampling, and hybrid sampling methods, have been widely applied to rebalance the training set, facilitating effective differentiation between majority and minority classes.ObjectiveHerein, we examine the effect of incorporating both data discretization and data resampling as steps in the analytical process on the classifier performance for class-imbalanced medical datasets. The order in which these two steps are carried out is compared in the experiments.MethodsTwo experimental studies were conducted, one based on 11 two-class imbalanced medical datasets and the other using 3 multiclass imbalanced medical datasets. In addition, the two discretization algorithms employed are ChiMerge and minimum description length principle (MDLP). On the other hand, the data resampling algorithms chosen for performance comparison are Tomek links undersampling, synthetic minority oversampling technique (SMOTE) oversampling, and SMOTE-Tomek hybrid sampling algorithms. Moreover, the support vector machine (SVM), C4.5 decision tree, and random forest (RF) techniques were used to examine the classification performances of the different approaches.ResultsThe results show that on average, the combination approaches can allow the classifiers to provide higher area under the ROC curve (AUC) rates than the best baseline approach at approximately 0.8%-3.5% and 0.9%-2.5% for twoclass and multiclass imbalanced medical datasets, respectively. Particularly, the optimal results for two-class imbalanced datasets are obtained by performing the MDLP method first for data discretization and SMOTE second for oversampling, providing the highest AUC rate and requiring the least computational cost. For multiclass imbalanced datasets, performing SMOTE or SMOTE-Tomek first for data resampling and ChiMerge second for data discretization offers the best performances.ConclusionsClassifiers with oversampling can provide better performances than the baseline method without oversampling.

The model's dependability is confirmed by metrics like precision, recall, and accuracy, all of which often exceed 90%. Loss values between 0.495 and 0.547 show that training optimized the system effectively.ConclusionBy enhancing the validation reliability, the K-fold cross-validation method highlights by what means the SegNet model segments objects in images across a range of datasets. These outcomes strengthen the confidence in the model's ability to generalize and highlight its potential for several practical uses in image segmentation.</p>","PeriodicalId":48978,"journal":{"name":"Technology and Health Care","volume":"33 2","pages":"863-876"},"PeriodicalIF":1.4,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143659298","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
