Abstract:

This article presents the development, results, validation, and implications of the TRansformative Outcomes and PrOcesses Scale (TROPOS), a 30-item, exploratory instrument to assess transformative learning (TL) among participants in educational programs. Core findings include a reliable (α = .884) and internally valid instrument with moderate correlation between transformative processes and outcomes ( r = .593). This study reflects the importance of critical reflection’s association with TL ( r = .541) but also places potential constraints on its prominence as a central component of TL, raising subtle questions into additional moderating or mediating constructs impacting TL.

Abstract:

Recent tragedies around the world have shown how accidents in the cable-stayed bridges can wreak havoc on the society. To ensure the safety of the cable-stayed bridges, several studies have estimated the cable tension force using the vibration of cables. Most of these methods for estimating the tension of a cable start with measuring the displacement of the cable. Recent development of commercial cameras provide opportunity for more convenient and efficient method for measuring the displacement of cable. However, traditional vision-based displacement measurement methods require the assumption that the movement of the cable should be measured in parallel to the camera plane. This assumption limits the installation location of the camera when measuring the displacement of a cable. Therefore, this study introduces a new vision-based cable displacement measurement system that can measure the displacement of a cable in various locations even when the camera is installed in the side of the cable. The proposed method consists of three phases: (1) camera projection matrix estimation, (2) cable tracking in the image coordinate, and (3) cable displacement estimation in the world coordinate. To validate the performance of the proposed method, a simulation-based validation test, a lab-scale validation test, and an on-site validation test were conducted. The simulation-based validation test verified the performance of the proposed method in an ideal condition, and the lab-scale validation test showed the performance of the method in physical environment. Finally, the on-site validation test showed that the proposed method can measure the cable displacement with a side view camera.

Abstract:

OBJECTIVE: To describe the research methodology used in development and validation of a scientific patient classification instrument for South African critical care patients. METHOD: This is a contextual, exploratory, and descriptive study. A two-phase validating model was used as a research method. In the development phase a literature review was carried out (domain identification), a provisional instrument developed (item generation), and a peer group discussion conducted (item formation). In the quantification phase 16 experts determined if both the items of the instrument and the entire instrument were content valid. The study was conducted within the framework of South African critical care nursing. RESULTS: In the peer group discussion the instrument was debated until consensus was reached. In the quantification phase, both the items of the instrument and the entire instrument were rated as content valid. CONCLUSIONS: Established patient classification systems can be successfully adapted and validated for local use.

Abstract:

Purpose:The Developmental Participation Skills Assessment (DPS) is designed to assist clinicians who work with hospitalized infants in thoughtfully and accurately identifying infant readiness and the capacity for an infant’s participation during caregiving interactions as well as offering an opportunity for the caregiver(s) to reflect upon the experience. Non-contingent caregiving impairs an infant’s autonomic, motor and state stability which interferes with regulation and negatively impacts neurodevelopment. By providing an organized way to assess readiness for care and capacity to participate in care, the infant may experience less stress and trauma. The DPS is completed by the caregiver following any caregiving interaction.Methods:Following a literature review, the development of the DPS items were extrapolated from well-established tools to achieve the most evidence-based criteria. Following item inclusion generation, the DPS went thru five phases of content validation: (a) Initial tool development and use by five NICU professionals as part of their developmental assessment. Expansion of the use of the DPS to include three more hospital NICUs within the health system (b) Item adjustment and use as part of a bedside training program at a Level IV NICU (c) Focus group of professionals using the DPS provided feedback and scoring was added (d) Pilot of DPS by multidisciplinary focus group in a Level IV NICU (e) Feedback form sent to 20 NICU experts and content of DPS finalized with reflective portion added.Main Outcome Variable:The establishment of an observational instrument, the Developmental Participation Skills Assessment, provides a means for identifying infant readiness, assessing the quality of infant participation, and prompting clinician reflective processing.Results:A total of 50 professionals across the Midwest (4 OT, 2 PT, 3 SLP, 41 nurses) utilized the DPS as a part of standard practice throughout the phases of development. Assessments were completed on both full-term and preterm hospitalized infants. Professionals within these phases utilized the DPS with infants within a wide range of adjusted gestational ages from 23 weeks to 60 weeks (20 weeks post term). Infants ranged in severity from breathing room air to being intubated on a ventilator. After all phases of development and expert panel feedback, with an additional 20 neonatal experts, the final result was the formation of an easy-to-use observational tool for assessing infant readiness prior to caregiving, participation during caregiving, and stability following caregiving. In addition, there is the opportunity for the clinician to reflect following the caregiving interaction in a concise, consistent way.Conclusion:Identifying readiness, and assessing the quality of the infant’s experience while also prompting clinician reflection following the experience has the potential to reduce toxic stress for the baby and promote mindfulness and contingency in caregiving.

Abstract:

The development of power grids is hindered by the limited transmission capacity of cable equipment, necessitating the accurate prediction of dynamic ampacity for cable expansion. This study focuses on the 110 kV cable intermediate joint, employing radial and axial inversion techniques for real-time conductor temperature inversion. Utilizing the Prophet time series model, we predict environmental changes and propose a dynamic ampacity evaluation method for cable intermediate joints. Experimental validation confirms the model’s accuracy, with prediction errors under 10 K, demonstrating its potential for enhancing cable system reliability and power grid development.

Abstract:

A MATLAB program was developed to estimate the hydrodynamic forces due to wave and current on an un-trenched submarine cable of diameter 9 in resting at the bottom of a 14-m depth sea, utilizing the Fourier decomposition method. The aim of this part of the research is to provide an accurate estimation of the hydrodynamic forces acting on the cable and to present a comparison between the Morison force model and Fourier decomposition force model. In addition, investigating the methods of fixation for submarine pipes and cables as the commonly used methods is of high cost for both manufacturing and installation and maintenance processes has many drawbacks. This research is concerned with the ability of the cable to be stable on the seabed using its own weight and, if required, estimating extra chain weight to be added helping stabilize the cable on the seabed. A validation of the developed program with UWAHYDRO program developed in the Western Australia University is introduced in this article.

Abstract:

Background and objectivesPoor identification of individuals with CKD is a major barrier to research and appropriate clinical management of the disease. We aimed to develop and validate a pragmatic electronic (e-) phenotype to identify patients likely to have CKD.Design, setting, participants, & measurementsThe e-phenotype was developed by an expert working group and implemented among adults receiving in- or outpatient care at five healthcare organizations. To determine urine albumin (UA) dipstick cutoffs for CKD to enable use in the e-phenotype when lacking urine albumin-to-creatinine ratio (UACR), we compared same day UACR and UA results at four sites. A sample of patients, spanning no CKD to ESKD, was randomly selected at four sites for validation via blinded chart review.ResultsThe CKD e-phenotype was defined as most recent eGFR <60 ml/min per 1.73 m2 with at least one value <60 ml/min per 1.73 m2 >90 days prior and/or a UACR of ≥30 mg/g in the most recent test with at least one positive value >90 days prior. Dialysis and transplant were identified using diagnosis codes. In absence of UACR, a sensitive CKD definition would consider negative UA results as normal to mildly increased (KDIGO A1), trace to 1+ as moderately increased (KDIGO A2), and ≥2+ as severely increased (KDIGO A3). Sensitivity, specificity, and diagnostic accuracy of the CKD e-phenotype were 99%, 99%, and 98%, respectively. For dialysis sensitivity was 94% and specificity was 89%. For transplant, sensitivity was 97% and specificity was 91%.ConclusionsThe CKD e-phenotype provides a pragmatic and accurate method for EHR-based identification of patients likely to have CKD.

Abstract:

Background & Objectives: Stroke is a leading cause of death and it causes significant long-term disabilities. It affects cognition and physical impairment in the patients. Cognitive impairments caused by stroke include loss of memory, disorientation, impaired attention, reasoning, and social perception. It may also lead to interaction deficit and inability to problem-solving, etc. The precise knowledge about the degree of cognitive impairment is essential to address the issue with appropriate measures. We aimed to develop a cognitive measurement scale for stroke patients. Methodology: The phenomenon was explored through in-depth interviews of 12 stroke survivors in different hospitals in Lahore, Pakistan. Seventeen items were generated. After factor analysis, 15 items were included in the scale and a pilot study was conducted on 15 participants. A sample of 106 patients was selected to administer the scale Cognitive Assessment Scale for Stroke Survivors (CASS) and Mini-Mental State Examination (MMSE) scale for concurrent validity. Results: The Principal Component Factor Analysis through Varimax rotation yielded three factors, e.g., ‘Social Cognition’, ‘Focus and Attention’, and ‘Orientation’. The results have shown significant values with good psychometric properties. The Cronbach’s Alpha value of the developed scale is 0.88 which indicates it as a highly reliable scale. Conclusion: This research reported that stroke survivors experience cognitive impairment after the stroke incidents. The developed scale to measure cognitive impairment after a stroke incident was proved to be valid and reliable, and can be used in medical practice.

Abstract:

OBJECTIVES: Although delirium detection and prevention practices are recommended in critical care guidelines, there remains a persistent lack of effective delirium education for ICU providers. To address this knowledge-practice gap, we developed an “ICU Delirium Playbook” to educate providers on delirium detection (using the Confusion Assessment Method for the ICU) and prevention. DESIGN: Building on our previous ICU Delirium Video Series, our interdisciplinary team developed a corresponding quiz to form a digital “ICU Delirium Playbook.” Playbook content validity was evaluated by delirium experts, and face validity by an ICU nurse focus group. Additionally, focus group participants completed the quiz before and after video viewing. Remaining focus group concerns were evaluated in semi-structured follow-up interviews. SETTING: Online validation survey, virtual focus group, and virtual interviews. SUBJECTS: The validation group included six delirium experts in the fields of critical care, geriatrics, nursing, and ICU education. The face validation group included nine ICU nurses, three of whom participated in the semi-structured feedback interviews. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: The 44-question quiz had excellent content validity (average scale-level content validity index [S-CVI] of individual items = 0.99, universal agreement S-CVI = 0.93, agreement κ ≥ 0.75, and clarity p ≥ 0.8). The focus group participants completed the Playbook in an average (sd) time of 53 (14) minutes, demonstrating significant improvements in pre-post quiz scores (74% vs 86%; p = 0.0009). Verbal feedback highlighted the conciseness, utility, and relevance of the Playbook, with all participants agreeing to deploy the digital education module in their ICUs. CONCLUSIONS: The ICU Delirium Playbook is a novel, first-of-its-kind asynchronous digital education tool aimed to standardize delirium detection and prevention practices. After a rigorous content and face validation process, the Playbook is now available for widespread use.

Abstract:

This study aims to develop an interactive module that supports student-centered learning and test the feasibility and the response of students to the interactive module. The product development stages use the Analyze, Design, Development, Implementation, and Evaluation procedure. The validation of the developed products was carried out by two material experts and two media experts. Products that have been revised and get a proper assessment are tested out in small groups consisting of 5 teachers and tested in large groups consisting of 30 students. The results show that the interactive module as a support for Student Centered Learning is very good and feasible to use. This is based on the results of the validation of material experts which show the percentage of the feasibility level of 95% and the results of the validation of the media experts show the percentage of the feasibility level of 80%, while the small group trials and large group trials show the percentage of the feasibility level of 87% and 86% respectively. Meaning that it is in the very feasible category.

Abstract:

Bone stress injuries are prevalent among athletes and military recruits and can significantly compromise training schedules. The development of an ankle–foot orthosis to reduce tibial load and enable a faster return to activity will require new device testing methodologies capable of capturing the contribution of muscular force on tibial strain. Thus, an actuated robotic surrogate leg was developed to explore how tibial strain changes with different ankle–foot orthosis conditions. The purpose of this work was to assess the reliability, scalability, and behavior of the surrogate. A dual actuation system consisting of a Bowden cable and a vertical load applied to the femur via a material testing system, replicated the action-reaction of the Achilles-soleus complex. Maximum and minimum principal strain, maximum shear strain, and axial strain were measured by instrumented strain gauges at five locations on the tibia. Strains were highly repeatable across tests but did not consistently match in vivo data when scaled. However, the stiffness of the ankle–foot orthosis strut did not systematically affect tibial load, which is consistent with in vivo findings. Future work will involve improving the scalability of the results to match in vivo data and using the surrogate to inform exoskeletal designs for bone stress injuries.

Abstract:

Two studies ( N = 621) were conducted to develop and initially validate the Communication Apprehension About Death Scale (CADS). In Study 1, 302 general public participants completed a preliminary list of 66 items. An exploratory factor analysis identified two distinct dimensions of communication apprehension about death: communication anxiety and communication avoidance. A different group of participants ( n = 319) participated in Study 2. Participants in Study 2 completed the CADS measure, a fear of death measure, and a general communication apprehension measure. Concurrent validity support was provided through the significant positive correlations between communication apprehension about death and fear of death as well as communication apprehension about death and general communication apprehension. Collectively, the results suggest that the CADS is a reliable and valid self-report measure of communication apprehension about death. We conclude with a discussion of the findings as well as future directions needed to more critically examine CADS.

Abstract:

During oil wellbore drilling processes, filter cake is formed on the sidewalls of the well hole due to filtration of drilling fluid particles. The filter cake is crucial to the drilling process, since it helps to maintain the wellbore hole, protects the drilling bit from jamming and facilitates the subsequent phases of the well development. The most important parameter for filter cake formation is its thickness and its variation due to drilling conditions. In this paper, the drilling fluid particles filtration process was simulated at conditions mimicking deep wellbore drilling. The drilling fluid was simulated as a non-Newtonian two-phase fluid of liquid and particles, utilizing an Eulerian-Eulerian approach. The model successfully predicted a filter cake thickness which agrees well with measurements and previous CFD work.

Abstract:

This article presents a test bed for comprehensive study of a cable-driven hyper-redundant robot in terms of mechanical design, kinematics analysis, and experimental verification. To design the hyper-redundant robot, the multiple section structure is used. Each section consists of two rotational joints, a link mechanism, and three cables. In this sense, two degrees of freedom are achieved. For kinematics analysis between the actuator space and joint space, each section of the development is treated as three spherical–prismatic–spherical chains and a universal joint chain (3-SPS-U), which results in a four-chain parallel mechanism model. In order to obtain the forward kinematics from the joint space to task space directly and easily, the coordinate frames are established by the geometrical rules rather than the traditional Denavit–Hartenburg (D-H) rules. To solve the problem of inverse kinematics analysis, we utilize the product of exponentials approach. Finally, a prototype of 24-degrees of freedom hyper-redundant robot with 12 sections and 36 cables is fabricated and an experiment platform is built for real-time control of the robot. Different experiments in terms of trajectories tracking test, positioning accuracy test, and payload test are conducted for the validation of both mechanical design and model development. Experiment results demonstrate that the presented hyper-redundant robot has fine position accuracy, flexibility with mean position error less than 2%, and good load capacity.

Abstract:

Objectives: Sepsis-3 recommends using the quick Sequential Organ Failure Assessment (qSOFA) score followed by SOFA score for sepsis evaluation. The SOFA is complex and unfamiliar to most emergency physicians, while qSOFA is insensitive for sepsis screening and may result in missed cases of sepsis. The objective of this study was to devise an easy-to-use simple SOFA score for use in the emergency department (ED). Methods: Retrospective study of ED patients with sepsis with in-hospital mortality as the primary outcome. A simple SOFA score was derived and validated and compared with SOFA and qSOFA. Results: A total of 3297 patients with sepsis were included, and in-hospital mortality was 10.1%. Simple SOFA had a sensitivity and specificity of 88% and 44% in the derivation set and 93% and 44% in the validation set for in-hospital mortality, respectively. The sensitivity and specificity of qSOFA was 38% and 86% and for SOFA was 90% and 50%, respectively. There were 2760 (84%) of 3297 qSOFA-negative (<2) patients. In this group, simple SOFA had a sensitivity and specificity of 86% and 48% in the derivation set and 91% and 48% in the validation set, respectively. Sequential Organ Failure Assessment was 86% sensitive and 57% specific in qSOFA-negative patients. For all encounters, the areas under the receiver–operator characteristic curves (AUROC) were 0.82 for SOFA, 0.78 (derivation) and 0.82 (validation) for simple SOFA, and 0.68 for qSOFA. In qSOFA-negative patients, the AUROCs were 0.80 for SOFA and 0.76 (derivation) and 0.82 (validation) for simple SOFA. Conclusions: Simple SOFA demonstrates similar predictive ability for in-hospital mortality from sepsis compared to SOFA. External validation of these findings is indicated.

Abstract:

Objectives: An early diagnosis of intensive care unit–acquired weakness (ICU-AW) is often not possible due to impaired consciousness. To avoid a diagnostic delay, we previously developed a prediction model, based on single-center data from 212 patients (development cohort), to predict ICU-AW at 2 days after ICU admission. The objective of this study was to investigate the external validity of the original prediction model in a new, multicenter cohort and, if necessary, to update the model. Methods: Newly admitted ICU patients who were mechanically ventilated at 48 hours after ICU admission were included. Predictors were prospectively recorded, and the outcome ICU-AW was defined by an average Medical Research Council score <4. In the validation cohort, consisting of 349 patients, we analyzed performance of the original prediction model by assessment of calibration and discrimination. Additionally, we updated the model in this validation cohort. Finally, we evaluated a new prediction model based on all patients of the development and validation cohort. Results: Of 349 analyzed patients in the validation cohort, 190 (54%) developed ICU-AW. Both model calibration and discrimination of the original model were poor in the validation cohort. The area under the receiver operating characteristics curve (AUC-ROC) was 0.60 (95% confidence interval [CI]: 0.54-0.66). Model updating methods improved calibration but not discrimination. The new prediction model, based on all patients of the development and validation cohort (total of 536 patients) had a fair discrimination, AUC-ROC: 0.70 (95% CI: 0.66-0.75). Conclusions: The previously developed prediction model for ICU-AW showed poor performance in a new independent multicenter validation cohort. Model updating methods improved calibration but not discrimination. The newly derived prediction model showed fair discrimination. This indicates that early prediction of ICU-AW is still challenging and needs further attention.

Abstract:

BackgroundDelirium has been shown to prolong the length of intensive care unit stay, hospitalization, and duration of ventilatory control, in addition to increasing the use of sedatives and increasing the medical costs. Although there have been a number of reports referring to risk factors for the development of delirium, no model has been developed to predict delirium in trauma patients at the time of admission. This study aimed to create a scoring system that predicts delirium in trauma patients.MethodsIn this single-center, retrospective, observational study, trauma patients aged 18 years and older requiring hospitalization more than 48 hours were included and divided into the development and validation cohorts. Univariate analysis was performed in the development cohort to identify factors significantly associated with prediction of delirium. The final scoring system for predicting delirium was developed using multivariate analysis and internal validation was performed.ResultsOf the 308 patients in the development cohort, 91 developed delirium. Clinical Frailty Score, fibrin/fibrinogen degradation products, low body mass index, lactate level, and Glasgow Coma Scale score were independently associated with the development of delirium. We developed a scoring system using these factors and calculated the delirium predictive score, which had an area under the curve of 0.85. In the validation cohort, 46 of 206 patients developed delirium. The area under the curve for the validation cohort was 0.86, and the calibration plot analysis revealed the scoring system was well calibrated in the validation cohort.DiscussionThis scoring system for predicting delirium in trauma patients consists of only five risk factors. Delirium prediction at the time of admission may be useful in clinical practice.Level of evidencePrognostic and epidemiological, level III.

Abstract:

Relevant to mobile health, the design of a portable electrocardiograph (ECG) device using AD823X microchips as the analog front-end is presented. Starting with the evaluation board of the chip, open-source hardware and software components were integrated into a breadboard prototype. This required modifying the microchip with the breadboard-friendly Arduino Nano board in addition to a data logger and a Bluetooth breakout board. The digitized ECG signal can be transmitted by serial cable, via Bluetooth to a PC, or to an Android smartphone system for visualization. The data logging shield provides gigabytes of storage, as the signal is recorded to a microSD card adapter. A menu incorporates the device’s several operating modes. Simulation and testing assessed the system stability and performance parameters in terms of not losing any sample data throughout the length of the recording and finding the maximum sampling frequency; and validation determined and resolved problems that arose in open-source development. Ultimately, a custom printed circuit board was produced requiring advanced manufacturing options of 2.5 mils trace widths for the small package components. The fabricated device did not degrade the AD823X noise performance, and an ECG waveform with negligible distortion was obtained. The maximum number of samples/second was 2380 Hz in serial cable transmission, whereas in microSD recording mode, a continuous ECG signal for up to 36 h at 500 Hz was verified. A low-cost, high-quality portable ECG for long-term monitoring prototype that reasonably complies with electrical safety regulations and medical equipment design was realized.

Abstract:

In this paper, we present a successful experimental validation of the velocity optimization for a cable car passing over a support. We apply the theoretical strategy developed in a previous work, refined by taking into account in a simple manner the hauling cable dynamics. The experiments at the ropeway Postal–Verano (South Tirol, Italy) have shown a significant reduction of the pendulum angle amplitude for both the descent and the ascending rides, as predicted from simulations. Furthermore, we measured a smoother progress of the torque at the driving engine during the vehicle support crossings.

Abstract:

SUMMARYIn accordance with strict requirements of portability, cheapness, and modularity, an innovative assistive device for hand disabilities has been developed and validated. This robotic orthosis is designed to be a low-cost, portable hand exoskeleton to assist people with physical disabilities in their everyday lives. Referring to hand opening disabilities, the authors have developed a methodology which, by starting from the geometrical characteristics of the patient's hand, defines the novel kinematic mechanism that better fits to the finger trajectories. The authors have validated the proposed novel mechanism by carrying out a Hand Exoskeleton System (HES) prototype, based on a single-phalanx mechanism, cable driven. The testing phase of the real prototype with a patient is currently on going.
