A Prospective Study on a Suture Force Feedback Device for Training and Evaluating Junior Surgeons in Anastomotic Surgical Closure.

BACKGROUND: Surgical reconstruction is a crucial stage in various surgeries, including pancreaticoduodenectomy, as it can significantly affect the surgical results. The objective was to design a suture force feedback (SFF) device that can precisely measure the suture force during surgical closures. Afterward, the device was used to train junior surgeons in surgical closure techniques. METHODS: The SFF was used to capture the suture force data of experienced surgeons. This data was utilized to train and assess junior surgeons. The SFF device had 2 tactile-based force sensors that measured the applied force. Whenever the applied force was not within the optimal force range, the device provided feedback to the surgeon. A workshop was conducted to train junior surgeons in surgical closure techniques to improve their suturing skills. RESULTS: Thirty-seven junior surgeons were enrolled in this training, of whom only 24 completed the 30-day training program. The pre-assessment results revealed that the force exerted by junior surgeons during suture knot-tying was uneven compared with that of the experienced surgeons, with a significant difference in the force exerted per knot throw (P = 0.005. Before the training program, junior surgeons applied a force of 3.89 ± 0.43 N, which was more than twice the force applied by experienced surgeons (1.75 ± 0.12 N). However, after completing the 30-day training program, their force improved to 2.35 ± 0.13 N. CONCLUSIONS: The SFF device was shown to be an encouraging training tool for improving the surgical closure dexterity and technique of the participating junior surgeons.

Negative feedback systems for modelling NF-κB transcription factor oscillatory activity.

Low-dimensional negative feedback systems (NFSs) were developed within a signal flow model to describe the oscillatory activities of NF-κB caused by interactions with its inhibitor IκBα. The NFSs were established as 3rd- and 4th-order linear systems containing unperturbed and perturbed negative feedback (NF) loops with constant or time-varying NF strengths and a feed-forward loop. NF-related analytical solutions to the NFSs representing the time courses of NF-κB and IκBα were determined and their exact mathematical relationship was found. The NFS's parameters were determined to fit the experimental time courses of NF-κB in TNF-α-stimulated embryonic fibroblasts, rela-/- embryonic fibroblasts reconstituted with RelA, C9L cells, GFP-p65 knock-in embryonic fibroblasts and embryogenic fibroblasts lacking Iκß and IκBε, LPS-stimulated IC-21 macrophages treated or not with DCPA, and anti-IgM-stimulated DT40 B-lymphocytes. The unperturbed and perturbed NFSs describing the above biosystems generated isochronous and non-isochronous solutions, depending on a constant or time-varying NF strength, respectively. The oscillation period of the NF-coupled solutions, the phase difference between them and the time delays in the appearance of cytoplasmic IκBα after stimulation of NF-κB were determined. A significant divergence between the IκBα solutions to the NFSs and the IκBα experimental courses led to a rejection of the NF coupling between NF-κB and IκBα in the above biosystems. It was shown that neither the linearity nor the low dimensionality of the NFSs altered the NF relationship and the divergence between the IκBα solutions to the NFS and IκBα experimental time courses. Although the NF relationship between IκBα and NF-κB was not confirmed in all the experimental data analyzed, delayed negative feedback was found in some cases.

Dose-Response Effects of MittEcho, a Measurement Feedback System, in an Indicated Mental Health Intervention for Children in Municipal and School Services in Norway.

Including routine client feedback can increase the effectiveness of mental health interventions for children, especially when implemented as intended. Rate of implementation, or dose, of such feedback interventions has been shown to moderate results in some studies. Variation in implementation and use of client feedback may also contribute to the mixed results observed within the feedback literature. This study evaluates dose-response associations of client feedback using a novel Measurement Feedback System (MFS) within an indicated group intervention. The primary aim was to determine whether the rate of MFS implementation predicts symptom reduction in anxiety and depression among school-aged children. The secondary aim was to assess whether the rate of MFS implementation influences children's satisfaction with the group intervention or their dropout rates. Data were collected via a randomized factorial study (clinicaltrials.gov NCT04263558) across 58 primary schools in Norway. Children aged 8 to 12 years (N = 701) participated in a group-based, transdiagnostic intervention targeting elevated symptoms of anxiety or depression. Half of the child groups also received the feedback intervention using the MittEcho MFS. Group leaders (N = 83), recruited locally, facilitated the interventions. The MFS dose was measured using the Implementation Index, which combines the use of MFS by both children and providers (group leaders) into a single dose variable. Results showed no significant additional effect of dose of MFS on change in depression or anxiety scores, on user satisfaction with the intervention or on intervention dropout. The discussion addresses potential reasons for these non-significant findings and implications for MFS implementation in preventive, group-based interventions in school settings.

Design of a Novel Delivery Efficiency Feedback System for Biphasic Dissolving Microarray Patches Based on Poly(Lactic Acid) and Moisture-Indicating Silica.

Dissolving microarray patches (DMAPs) represent an innovative approach to minimally invasive transdermal drug delivery, demonstrating efficacy in delivering both small and large therapeutic molecules. However, concerns raised in end-user surveys have hindered their commercialization efforts. One prevalent issue highlighted in these surveys is the lack of clear indicators for successful patch insertion and removal time. To address this challenge, a color-change-based feedback system is devised, which confirms the insertion and dissolution of DMAPs, aiming to mitigate the aforementioned problems. The approach combines hydrophilic needles containing model drugs (fluorescein sodium and fluorescein isothiocyanate (FITC)-dextran) with a hydrophobic poly(lactic acid) baseplate infused with moisture-sensitive silica gel particles. The successful insertion and subsequent complete dissolution of the needle shaft are indicated by the progressive color change of crystal violet encapsulated in the silica. Notably, distinct color alterations on the baseplate, observed 30 min and 1 h after insertion for FITC-dextran and fluorescein sodium DMAPs respectively, signal the full dissolution of the needles, confirming the complete cargo delivery and enabling timely patch removal. This innovative feedback system offers a practical solution for addressing end-user concerns and may significantly contribute to the successful commercialization of DMAPs by providing a visualized drug delivery method.

Evaluating User Perceptions of a Vibrotactile Feedback System in Trunk Stabilization Exercises: A Feasibility Study.

Low back pain patients often have deficits in trunk stability. For this reason, many patients receive physiotherapy treatment, which represents an enormous socio-economic burden. Training at home could reduce these costs. The problem here is the lack of correction of the exercise execution. Therefore, this feasibility study investigates the applicability of a vibrotactile-controlled feedback system for trunk stabilisation exercises. A sample of 13 healthy adults performed three trunk stabilisation exercises. Exercise performance was corrected by physiotherapists using vibrotactile feedback. The NASA TLX questionnaire was used to assess the practicability of the vibrotactile feedback. The NASA TLX questionnaire shows a very low global workload 40.2 [29.3; 46.5]. The quality of feedback perception was perceived as good by the subjects, varying between 69.2% (anterior hip) and 92.3% (lower back). 80.8% rated the feedback as helpful for their training. On the expert side, the results show a high rating of movement quality. The positive evaluations of the physiotherapists and the participants on using the vibrotactile feedback system indicate that such a system can reduce the trainees fear of independent training and support the users in their training. This could increase training adherence and long-term success.

Demand Analysis of a German Emergency Medical Service Feedback System.

BACKGROUND: The number of emergency medical service (EMS) calls in Germany is continuously increasing. The initial assessment, the pre-hospital care and the choice of hospital for further care by the EMS influences the patient's outcome and are the basis for further care in hospital. However, the EMS does not receive any official feedback on its decisions. OBJECTIVES: This study evaluates the demand for a feedback system from the emergency department (ED) to the EMS, what it should contain, and how it could be integrated in the electronic clinical systems. METHODS: A semi-structured interview guideline for expert interviews with members of EMS staff (n = 6) and ED staff (n = 17) was developed. A mockup to visualise a possible implementation was designed and included in the interview. RESULTS: There is a significant demand for feedback on pre-diagnosis, pre-hospital care and handover of patients from the EMS to the ED. The EDs are very interested in improving the collaboration with the paramedic services through feedback. CONCLUSION: A feedback system is strongly desired by various EMS stakeholders and, according to them, could improve both EMS and ED collaboration and overall patient care.

Is hyperinsulinemia a possible clinical explanation underlying the myth of Erysichthon?

BACKGROUND: An insulinoma is an endocrine tumor of the pancreas, originating from the beta cells, and has a prevalence of 4 cases per 1 million patients. Insulinomas often follow a "90% rule": 90% are benign [1, 2], 90% originate in the pancreas, 90% are approximately 2 cm wide, and 90% are isolated. Individuals with an insulinoma may have episodic bouts of hyperinsulinemic hypoglycemia. Typically, an insulinoma is indicated by hypoglycemic symptoms which are a result of catecholamine reaction and neuroglycopenia. There is increased secretion of insulin in patients with an insulinoma despite having lower glucose levels. PURPOSE: This paper examines the myth of Erysichthon and speculates whether the symptoms experienced by him are possibly related to those found in patients with an hyperinsulinoma. METHODS: The myth of Erysichthon was taken from various sources (i.e. Hesiod, Callimachus, Ovid) and examined. Symptoms of Erysichthon were then examined. RESULTS: The myth of Erysichthon depicts various sympathoadrenal and neuroglycopenic symptoms including anxiety and abnormal behaviour which can be found in insulinomas. Insulinomas may often present a diagnostic challenge due to their deceptive nature and overlapping symptoms with other disorders such as neurologic disease. Insulinomas inducing weight loss resemble Calamachus's account of Erysichthon whose body is finally emaciated, even though having polyphagia. CONCLUSION: The myth of Erysichthon provides an interesting range of clinical symptoms which I have argued relate to symptoms found in patients with an insulinoma. Although, insulinomas were unknown in ancient medical lore, this paper has speculated that based on Erysichthon's symptoms, the possibility of an insulinoma cannot be ruled out.

Learning analytics for lifelong career development: a framework to support sustainable formative assessment and self-reflection in programs developing career self-efficacy.

Among myriad complex challenges facing educational institutions in this era of a rapidly evolving job marketplace is the development of career self-efficacy among students. Self-efficacy has traditionally been understood to be developed through the direct experience of competence, the vicarious experience of competence, social persuasion, and physiological cues. These four factors, and particularly the first two, are difficult to build into education and training programs in a context where changing skills make the specific meaning of graduate competence largely unknown and, notwithstanding the other contributions in this collection, largely unknowable. In response, in this paper we argue for a working metacognitive model of career self-efficacy that will prepare students with the skills needed to evaluate their skills, attitudes and values and then adapt and develop them as their career context evolves around them. The model we will present is one of evolving complex sub-systems within an emergent milieu. In identifying various contributing factors, the model provides specific cognitive and affective constructs as important targets for actionable learning analytics for career development.

A five-year (2017-2021) time series evaluation of patient-reported informal healthcare payments in Romania.

Low wages of health professionals are widely recognized as one of the drivers of informal payments in Romania's healthcare system. In January 2018, the government increased wages by an average of 70% to 172% in the public healthcare sector. This study examined the trends in patient-reported informal healthcare payments, discussing the effect of a one-time wage increase in 2018 and the impact of the COVID-19 pandemic in 2020 and 2021. It draws on monthly survey data of patient-reported informal payments collected between January 2017 and December 2021. We analyzed three periods: before the wage rise ("low pay"), between the wage rise and the COVID-19 pandemic ("high pay"), and during the COVID-19 pandemic. We found that patient-reported informal payments decreased between the "low pay" and "high pay" period but with a sharper decline during the COVID-19 pandemic. The share of respondents willing to report informal payments increased during the "high pay" period, indicating a stronger willingness to voice dissatisfaction with health services and informal payments, but slowed down during the first lockdown in 2020. Informal payments were more frequently reported in larger hospitals and the poorest geographical areas. While the 2018 wage increase may have contributed to less prevalent informal payments, survey coverage and design must be improved to draw robust, system-level conclusions to inform tailored policy actions.

Investigating the efficacy of a tactile feedback system to increase the gait speed of older adults.

The objective of this study was to determine (1) if a novel haptic feedback system could increase the walking speed of older adults while it is being employed during overground walking and (2) whether the frequency at which this feedback was presented would have a differential impact on the ability of users to change walking speed while it was present. Given that peak thigh extension has been found to be a biomechanical surrogate for stride length, and consequently gait speed, vibrotactile haptic feedback was provided to the participants' thighs as a cue to increase peak thigh extension while the effect on gait speed was monitored. Ten healthy community-dwelling older adults (68.4 ± 4.1 years) participated. Participants' peak thigh extension, cadence, normalized stride length and velocity, along with their coefficients of variation (COV) were compared across baseline normal and fast walking (with no feedback) and three different frequency of feedback conditions. The findings indicated that, compared to self-selected normal and fast walking speeds, peak thigh extension was significantly increased when feedback was present and after it was withdrawn in a post-test. An increase in thigh extension led to an increase in stride length and, consequently, an increase in stride velocity compared to normal speed. There were no significant differences in the gait parameters as a function of feedback frequency during its application. In conclusion, while present, the haptic feedback system increased thigh extension and walking speed in older adults regardless of the feedback frequency and when the feedback was withdrawn, participants could maintain an increase in those parameters.

Experiences and results from using a novel clinical feedback system in routine stoma care nurse follow-up of patients with an ostomy: a longitudinal study.

BACKGROUND: A faecal or urinary ostomy may be lifesaving. However, it involves significant bodily change, and the adjustment process to life with an ostomy includes a broad spectre of physical and psychosocial challenges. Thus, new interventions are needed to improve adaptation to living with an ostomy. This study aimed to examine experiences and outcomes using a new clinical feedback system with patient-reported outcome measures in ostomy care. METHODS: In this longitudinal explorative study, 69 ostomy patients were followed by a stoma care nurse in an outpatient clinic, using a clinical feedback system postoperatively at 3, 6 and 12 months. The patients responded electronically to the questionnaires before each consultation. The Generic Short Patient Experiences Questionnaire was used to measure patient experiences and satisfaction with follow-up. The Ostomy Adjustment Scale (OAS) measured adjustment to life with an ostomy, and the Short Form-36 (SF-36) assessed the patient's health-related quality of life. Longitudinal regression models with time as an explanatory (categorical) variable were used to analyse changes. The STROBE guideline was applied. RESULTS: The patients were satisfied with their follow-up (96%). Especially, they felt they received sufficient and individualised information, were involved in treatment decisions, and benefited from the consultations. The OAS subscale scores for 'daily activities', 'knowledge and skills' and 'health' improved over time (all p < 0.05), as did the physical and mental component summary scores of the SF-36 (all p < 0.05). Effect sizes of changes were small (0.20-0.40). Sexuality was the most challenging factor reported. CONCLUSIONS: The clinical feedback system could be helpful because outpatient follow-ups for ostomy patients may be more tailored when clinicians use clinical feedback systems. However, further development and testing are needed.

Recent Progress of Tactile and Force Sensors for Human-Machine Interaction.

Human-Machine Interface (HMI) plays a key role in the interaction between people and machines, which allows people to easily and intuitively control the machine and immersively experience the virtual world of the meta-universe by virtual reality/augmented reality (VR/AR) technology. Currently, wearable skin-integrated tactile and force sensors are widely used in immersive human-machine interactions due to their ultra-thin, ultra-soft, conformal characteristics. In this paper, the recent progress of tactile and force sensors used in HMI are reviewed, including piezoresistive, capacitive, piezoelectric, triboelectric, and other sensors. Then, this paper discusses how to improve the performance of tactile and force sensors for HMI. Next, this paper summarizes the HMI for dexterous robotic manipulation and VR/AR applications. Finally, this paper summarizes and proposes the future development trend of HMI.

An interactive feedback system for increasing hand antisepsis adherence in stationary intensive care.

BACKGROUND: Pathogens causing infections are in many cases transmitted via the hands of personnel. Thus, hand antisepsis has strong epidemiological evidence of infection prevention. Depending on various factors, hand antisepsis adherence ranges between 9.1% and 85.2%. AIM: To evaluate a new transponder system that reminded medical staff to use an alcohol-based hand rub based on indication by giving real-time feedback, to detect hand antisepsis adherence. METHODS: The monitoring system consisted of three components: a portable transponder detecting alcohol-based hand rub and able to give feedback; a beacon recognizing entries to and exits from the patient's surroundings; and a sensor placed at the hand-rub dispensers to count the number of hand rubs. With these components, the system provided feedback when hand antisepsis was not conducted although it was necessary according to moments 1, 4, and 5 of hand antisepsis. Adherence was measured in two use-cases with five phases, starting with the baseline measurement followed by intervention periods and phases without intervention to test the sustainability of the feedback. FINDINGS: Using the monitoring system, hand antisepsis adherence was increased by up to 104.5% in comparison to the baseline measurement. When the intervention ceased, however, hand antisepsis adherence decreased to less than or equal to the baseline measurement. CONCLUSION: A short-term intervention alone is not sufficient to lead to a long-term change in hand antisepsis adherence. Rather, permanent feedback and/or the integration in a multi-modal intervention strategy are necessary.

Factors associated with leakage in patients with an ostomy: A cross-sectional study.

AIMS: To explore the associations between sociodemographic and clinical data, the patient's knowledge and skills, and relationship to healthcare professionals with leakage from an ostomy. DESIGN: Cross-sectional. METHODS: This study included 160 patients with a colostomy, ileostomy, or urostomy. Leakage was the dependent variable and was assessed by self-report. Sociodemographic and clinical data and the Ostomy Adjustment Scale subscores, 'knowledge and skills' and 'health care professionals' were independent variables. Spearman's rho and multivariate partial least squares regression analysis were used to estimate possible factors associated with leakage. RESULTS: Of the participants, 13.8% had leakage weekly or more often, 16.3% more often than once a month and 37, 5% had leakage more seldom than once a month. The most important risk factors for leakage were (1) having an ostomy placement that does not meet international guidelines, (2) not having an optimal relationship with health professionals, (3) having a diagnosis other than cancer, (4) not having proper knowledge and skills in ostomy care, (5) not having a colostomy, (6) having a convex baseplate, (7) having an oval ostomy, and (8) being dependent on others for ostomy care. The independent variables in the PLS- model explained 31% of the variance in leakage. PATIENT OR PUBLIC CONTRIBUTION: We thank the patients in the user panel for their help during the study.

Development and Validation of an Artificial Intelligence-Based Motion Analysis System for Upper Extremity Rehabilitation Exercises in Patients with Spinal Cord Injury: A Randomized Controlled Trial.

In this study, we developed an AI-based real-time motion feedback system for patients with spinal cord injury (SCI) during rehabilitation, aiming to enhance their interest and motivation. The effectiveness of the system in improving upper-limb muscle strength during the Thera band exercises was evaluated. The motion analysis program, including exercise repetition counts and calorie consumption, was developed using MediaPipe, focusing on three key motions (chest press, shoulder press, and arm curl) for upper extremity exercises. The participants with SCI were randomly assigned to the experimental group (EG = 4) or control group (CG = 5), engaging in 1 h sessions three times a week for 8 weeks. Muscle strength tests (chest press, shoulder press, lat pull-down, and arm curl) were performed before and after exercises. Although both groups did not show significant differences, the EG group exhibited increased strength in all measured variables, whereas the CG group showed constant or reduced results. Consequently, the computer program-based system developed in this study could be effective in muscle strengthening. Furthermore, these findings may serve as a valuable foundation for future AI-driven rehabilitation exercise systems.

Optimal Underwater Acoustic Warfare Strategy Based on a Three-Layer GA-BP Neural Network.

A defense platform is usually based on two methods to make underwater acoustic warfare strategy decisions. One is through Monte-Carlo method online simulation, which is slow. The other is by typical empirical (database) and typical back-propagation (BP) neural network algorithms based on genetic algorithm (GA) optimization, which is less accurate and less robust. Therefore, this paper proposes a method to build an optimal underwater acoustic warfare feedback system using a three-layer GA-BP neural network and dropout processing of the neural network to prevent overfitting, so that the three-layer GA-BP neural network has adequate memory capability while still having suitable generalization capability. This method improves the accuracy and stability of the defense platform in making underwater acoustic warfare strategy decisions, thus increasing the survival probability of the defense platform in the face of incoming torpedoes. This paper uses the optimal underwater acoustic warfare strategies corresponding to incoming torpedoes with different postures as the sample set. Additionally, it uses a three-layer GA-BP neural network with an overfitting treatment for training. The prediction results have less error than the typical single-layer GA-BP neural network, and the survival probability of the defense platform improves by 6.15%. This defense platform underwater acoustic warfare strategy prediction method addresses the impact on the survival probability of the defense platform due to the decision speed and accuracy.

Measurement feedback system implementation in public youth mental health treatment services: a mixed methods analysis.

BACKGROUND: Prior studies indicate the effectiveness of measurement-based care (MBC), an evidence-based practice, in improving and accelerating positive outcomes for youth receiving behavioral health services. MBC is the routine collection and use of client-reported progress measures to inform shared decision-making and collaborative treatment adjustments and is a relatively feasible and scalable clinical practice, particularly well-suited for under-resourced community mental health settings. However, uptake of MBC remains low, so information on determinants related to MBC practice patterns is needed. METHODS: Quantitative and qualitative data from N = 80 clinicians who implemented MBC using a measurement feedback system (MFS) were merged to understand and describe determinants of practice over three study phases. Quantitative, latent class analysis identified clinician groups based on participants' ratings of MFS acceptability, appropriateness, and feasibility and describes similarities/differences between classes in clinician-level characteristics (e.g., age; perceptions of implementation climate; reported MFS use; phase I). Qualitative analyses of clinicians' responses to open-ended questions about their MFS use and feedback about the MFS and implementation supports were conducted separately to understand multi-level barriers and facilitators to MFS implementation (phase II). Mixing occurred during interpretation, examining clinician experiences and opinions across groups to understand the needs of different classes of clinicians, describe class differences, and inform selection of implementation strategies in future research (phase III). RESULTS: We identified two classes of clinicians: "Higher MFS" and "Lower MFS," and found similarities and differences in MFS use across groups. Compared to Lower MFS participants, clinicians in the Higher MFS group reported facilitators at a higher rate. Four determinants of practice were associated with the uptake of MBC and MFS in youth-serving community mental health settings for all clinicians: clarity, appropriateness, and feasibility of the MFS and its measures; clinician knowledge and skills; client preferences and behaviors; and incentives and resources (e.g., time; continuing educational support). Findings also highlighted the need for individual-level implementation strategies to target clinician needs, skills, and perceptions for future MBC and MFS implementation efforts. CONCLUSION: This study has implications for the adoption of evidence-based practices, such as MBC, in the context of community-based mental health services for youth.

Frequency-Modulated Signal Measurement Using Closed-Loop Methodology.

Frequency-modulated (FM) signals are widely used in sensing, measurement, and signal detection due to their strong anti-interference and easy transmission characteristics. Although the high-precision measurement methods for static signals are quite complete, the high-precision measurement methods for dynamic FM signals still need to be studied, and the measurement accuracy in the high-sampling system still has room for improvement. Traditionally, the equal-precision measurement method is widely applied in most scenarios. However, its accuracy is limited by the quantization error of ±1 word and the sampling gate time, making it difficult to improve the frequency measurement accuracy while ensuring a high sampling rate at the same time. In this paper, a high-precision feedback frequency measurement system with the capability to eliminate the quantization error of ±1 word is proposed. The proposed system consists of two stages, the rough measurement stage based on the equal-precision measurement method and the precise measurement stage based on the negative feedback tracking architecture using the phase-frequency detector (PFD) and direct digital synthesizer (DDS). The effectiveness and feasibility of the system are verified by both simulation and experiment. At the sampling rate of 2 kHz, the frequency measurement accuracy is improved by more than 30 dB.

Target temperature management versus normothermia without temperature feedback systems for out-of-hospital cardiac arrest survivors.

OBJECTIVE: The clinical benefit of automatic temperature control devices remains unclear. We investigated the outcomes of out-of-hospital cardiac arrest (OHCA) survivors who had undergone either target temperature management (TTM) with a temperature feedback system (TFS) or maintenance of normothermia without a TFS during post-resuscitation care. METHODS: This study was a retrospective analysis of a multicenter prospective cohort of OHCA survivors who had received postcardiac arrest care from August 2014 to December 2018. The overlap propensity score weighting method was applied for adjustment between groups. RESULTS: A total of 405 OHCA survivors were included. TTM with a TFS and normothermia without a TFS were applied to 318 and 87 patients, respectively. Fever events were more common in patients with normothermia without a TFS. After propensity score matching, no statistically significant differences were observed in the 1-month good neurologic outcome (odds ratio 0.99, 95% confidence interval [CI] 0.56-1.25) or survival rate (odds ratio 1.25, 95% CI 0.88-1.78). CONCLUSION: No significant differences in the 1-month neurologic outcome were observed between patients receiving TTM with a TFS and those undergoing normothermia without a TFS.
