A pilot study evaluating online training for therapist delivery of interpersonal psychotherapy for eating disorders.

OBJECTIVE: Individuals with eating disorders (EDs) often do not receive evidence-based care, such as interpersonal psychotherapy (IPT), partly due to lack of accessible training in these treatments. The standard method of training (i.e., in-person workshops) is expensive and time consuming, prompting a need for more scalable training tools. The primary aim of this pilot and open trial was to examine the effects of an IPT online training platform on training outcomes (i.e., IPT fidelity, knowledge, and acceptance) and, secondarily, whether online training was different from in-person training (using a comparative sample from a separate study) in terms of training outcomes and patient symptoms. METHOD: Participants were therapists (N = 60) and student patients (N = 42) at 38 college counseling centers. Therapists completed baseline questionnaires and collected data from a student patient with ED symptoms. Therapists then participated in an IPT online training program and completed post-training assessments. RESULTS: Following online training, acceptance of evidence-based treatments, therapist knowledge of IPT, therapist acceptance of IPT, and treatment fidelity increased; acceptance of online training was high at baseline and remained stable after training. Using the 90% confidence interval on outcome effect sizes, results suggested IPT online training was not different from in-person training on most outcomes. Results are based on 60% of therapists who originally enrolled due to high dropout rate of therapist participants. CONCLUSIONS: Findings from this preliminary pilot study support the use of IPT online training, which could increase access to evidence-based ED treatment and improve patient care. PUBLIC SIGNIFICANCE: Lack of accessible therapist training has contributed to many therapists not delivering, and therefore many patients not receiving, evidence-based treatment. This study evaluated a highly disseminable online training and compared outcomes to traditional in-person training and found that training and patient outcomes were not different. Online training has the potential to enhance access to evidence-base care, which could in turn optimize patient outcomes.

Effect of post-discharge online kangaroo care training on breastfeeding self-efficacy in mothers with preterm infants: A randomised controlled study.

BACKGROUND: Preterm newborns face many health problems due to their incomplete intrauterine development and the immaturity of their systems. One of these problems concerns nutrition. This study aimed to determine the effect of online kangaroo care (KC) training provided post-discharge on breastfeeding self-efficacy in mothers with preterm infants. METHODS: This research was conducted as an experimental study with a randomised control group. Two groups were formed: kangaroo care and control. The sample of the study consisted of 68 mothers of preterm infants. The mothers in the KC group were given online KC training after discharge from the hospital. The mothers were asked to perform KC regularly, at least once a day, for 20 min, 7 days a week. The Breastfeeding Self-Efficacy Scale was administered to the mothers before and after training. RESULTS: The results of the study revealed that the difference between the pre-test and post-test breastfeeding self-efficacy scores was statistically significantly higher among the mothers who received online KC training compared with the controls (p < 0.001). CONCLUSION: According to the results of our research carried out in this context, the mothers who received online KC training had increased breastfeeding self-efficacy compared to those in the control group.

Promoting Informed Decisions About Colorectal Cancer Screening in Older Adults (PRIMED Study): a Physician Cluster Randomized Trial.

BACKGROUND: For adults aged 76-85, guidelines recommend individualizing decision-making about whether to continue colorectal cancer (CRC) testing. These conversations can be challenging as they need to consider a patient's CRC risk, life expectancy, and preferences. OBJECTIVE: To promote shared decision-making (SDM) for CRC testing decisions for older adults. DESIGN: Two-arm, multi-site cluster randomized trial, assigning physicians to Intervention and Comparator arms. Patients were surveyed shortly after the visit to assess outcomes. Analyses were intention-to-treat. PARTICIPANTS AND SETTING: Primary care physicians affiliated with 5 academic and community hospital networks and their patients aged 76-85 who were due for CRC testing and had a visit during the study period. INTERVENTIONS: Intervention arm physicians completed a 2-h online course in SDM communication skills and received an electronic reminder of patients eligible for CRC testing shortly before the visit. Comparator arm received reminders only. MAIN MEASURES: The primary outcome was patient-reported SDM Process score (range 0-4 with higher scores indicating more SDM); secondary outcomes included patient-reported discussion of CRC screening, knowledge, intention, and satisfaction with the visit. KEY RESULTS: Sixty-seven physicians (Intervention n=34 and Comparator n=33) enrolled. Patient participants (n=466) were on average 79 years old, 50% with excellent or very good self-rated overall health, and 66% had one or more prior colonoscopies. Patients in the Intervention arm had higher SDM Process scores (adjusted mean difference 0.36 (95%CI (0.08, 0.64), p=0.01) than in the Comparator arm. More patients in the Intervention arm reported discussing CRC screening during the visit (72% vs. 60%, p=0.03) and had higher intention to follow through with their preferred approach (58.0% vs. 47.1, p=0.03). Knowledge scores and visit satisfaction did not differ significantly between arms. CONCLUSION: Physician training plus reminders were effective in increasing SDM and frequency of CRC testing discussions in an age group where SDM is essential. TRIAL REGISTRATION: The trial is registered on clinicaltrials.gov (NCT03959696).

Positive Emotions Training (PoET) as an online intervention to improve mental health: a feasibility study.

BACKGROUND: Positive psychology interventions are known to have an impact on mental health as well as on a number of beneficial characteristics like optimism, gratitude and self-efficacy. The Positive Emotions Training (PoET) is one of the first holistic training programs covering eleven positive psychology constructs. The goal of this study was to test PoET's feasibility in the general population and to assess possible effects on positive and negative mental health factors. Additionally, possible effects on optimism, gratitude, happiness, resilience, and self-efficacy were examined. METHODS: The sample (n = 101) was not randomized. Participants were allocated to PoET (n = 55) or control group (n = 46) that did not receive treatment initially. The PoET group completed two training sessions (3.5 h each) that were conducted in an online format with groups of about 30 people. All participants completed positive and negative mental health measures at the beginning of the first training session and at the beginning of the second one as well as 30 days after the second session. Two-factorial repeated measures ANOVAs were conducted to test for possible effects of PoET on mental health. RESULTS: The results showed that the contents were comprehensible and that the conduction of the training was feasible overall. In addition, a significant decrease of depression and anxiety symptoms as well as a significant increase of optimism were found in the PoET group. No significant changes were found in the control group. CONCLUSIONS: Results indicate that PoET is an applicable intervention for improving mental health in the general population. TRIAL REGISTRATION: Retrospectively registered at ClinicalTrials.gov on 21/02/2023 (Identifier/Trial registration number: NCT05737251).

Feasibility and self-perceived effectiveness of an online training program on dysphagia in residential aged care homes in mainland China.

BACKGROUND: With a rapidly aging population in mainland China, dysphagia has become one of the common geriatric disorders which creates a huge demand on speech and language therapists (SLTs). The major challenge is the shortage of SLTs in China. In addition, frontline practitioners in mainland China may not be well equipped with the knowledge and practical skills in dysphagia management due to lack of systematic training and the work nature. AIMS: This study evaluates the self-perceived effectiveness and feasibility of an online training program that aims to enhance the self-assessed knowledge and skills of SLTs providing dysphagia care in residential aged care homes. METHODS AND PROCEDURES: Sixteen SLTs working in a residential aged care homes in mainland China attended a three-hour pilot online training program which consists of didactic lecture and practical skills activity components. A total of 10 participants completed an online questionnaire one month after the training to evaluate the feasibility and effectiveness of this online training program. OUTCOMES AND RESULTS: The preliminary results demonstrated participants' self-perception of high training effectiveness in theoretical knowledge and practical skills. A majority of the participants perceived that the training enhanced their theoretical knowledge and all of them perceived that they acquired practical skills. All respondents were satisfied with the online training approach. They also highlighted the advantage and challenges of the online training approach. CONCLUSIONS AND IMPLICATIONS: Online training is an effective and feasible approach for theoretical knowledge and practical skills transfer in SLT training and could ultimately benefit the delivery of services for individuals with dysphagia in mainland China. WHAT THIS PAPER ADDS: What is already known on the subject Previous studies have shown that online training approach is as effective as face-to-face training in increasing professional knowledge. Online training programs may be more cost efficient and time efficient when compared with face-to-face training. What this study adds The present study provided preliminary evidence to support the feasibility and effectiveness of using online training on dysphagia for speech and language therapists working in residential aged care homes in mainland China. What are the clinical implications of this work? From the participants' perception, online training approach is effective and feasible in delivering theoretical knowledge and practical skills. It may be a better training approach for mainland China considering the lack of expertise and accessibility to training.

A virtual training program for improving cultural competence among academic nurse educators.

BACKGROUND: Everyday, nursing students interact with culturally diverse clients. Nursing education recognizes that cultural competence is a necessary outcome of nursing programs. Nurse educators expect all nursing students to provide culturally congruent care to multicultural clients. Therefore, nurse educators must be culturally competent in order to prepare culturally competent nursing students for clinical practice. This study aimed to evaluate the effect of virtual training program on the cultural competence of academic nurse educators. METHODS: This randomized controlled study included nurse educators working in six nursing schools affiliated with medical universities of Kerman province in southeastern Iran. Sixty-nine nurse educators were randomly assigned to the intervention (n = 35) and control (n = 34) groups. The training program consisted of three 2-hour sessions for a month. Cultural Diversity Questionnaire for Nurse Educators Revised (CDQNE-R) was used to evaluate the cultural competence of educators before and one month after the virtual training program. RESULTS: Both the intervention (3.29 ± 0.58) and control (3.24 ± 0.58) groups demonstrated a similar level of cultural competence before the training program (t = 0.05, p = 0.95). After the training, the intervention group showed a significant increase in cultural competence (3.80 ± 0.7) compared to the control group (3.23 ± 0.67). This improvement resulted in culturally competent participants becoming culturally proficient, as evidenced by a large effect size (t = -4.76, p = 0.001). CONCLUSION: The virtual training program had a positive impact on the cultural competence of nurse educators. Given the importance of cultural competence in nursing education, continuing education programs that focus on strengthening the cultural competence of nurse educators should be prioritized. The experiences gained from implementing virtual training programs can serve as a valuable resource for nurse educators seeking to enhance their cultural competence.

Health literacy education at the time of COVID-19: development and piloting of an educational programme for university health professional students in 4 European countries.

BACKGROUND: Health literacy has a strong influence on individual health outcomes and the sustainability of healthcare systems. Healthcare professionals often overestimate patients' health literacy levels and lack adequate competencies to address limited health literacy effectively. Therefore, promoting understanding through effective health communication between professionals and citizens is becoming increasingly important. Although health literacy has recently gained more attention, health literacy educational programmes targeting future healthcare professionals are still scarce, especially in Europe. This study describes the piloting process of a pan-European health literacy educational programme and shows how the educational material is being used during time of crisis such as the COVID-19 pandemic. METHODS: The educational programme was developed through the definition of an educational philosophy and iterative co-creation processes consisting of stakeholders' consultations, material development and pilots with students. The evaluation was carried out in Italy through four pilot tests involving 107 students of health-related degrees. An evaluation questionnaire and a pre-post test were developed and used to collect students' and educators' feedback (quantitative and qualitative) and assess changes in health literacy awareness, respectively. Three additional pilots were organized in Italy and Germany mostly during the COVID-19 pandemic to evaluate the feasibility of the educational programme through online and hybrid learning, respectively. RESULTS: The pilots received positive feedback from both students and educators. Students were highly satisfied with the courses, reported their relevance for their future profession and appreciated the interactive teaching methods. The pre-post test showed a significant improvement in health literacy awareness after the training. Educators reported the adequacy and flexibility of the training material, the ease of transferability of the content of the lessons into practice, and the validity of the tested options to integrate the educational programme into the curricula. CONCLUSIONS: Our comprehensive, evidence-based educational programme contributes to addressing the existing challenges in Europe, and its flexibility allows for easy integration in the curricula, through different options, hence supporting a widespread uptake in the European Union and maybe beyond. Health literacy education is a useful tool to improve citizens' access to healthcare information and services, achieve better health outcomes and support healthcare systems' sustainability.

Wireless Channel Prediction of GRU Based on Experience Replay and Snake Optimizer.

Aiming at the problem of poor prediction accuracy of Channel State Information (CSI) caused by fast time-varying channels in wireless communication systems, this paper proposes a gated recurrent network based on experience replay and Snake Optimizer for real-time prediction in real-world non-stationary channels. Firstly, a two-channel prediction model is constructed by gated recurrent unit, which adapts to the real and imaginary parts of CSI. Secondly, we use the Snake Optimizer to find the optimal learning rate and the number of hidden layer elements to build the model. Finally, we utilize the experience pool to store recent historical CSI data for fast learning and complete learning. The simulation results show that, compared with LSTM, BiLSTM, and BiGRU, the gated recurrent network based on experience replay and Snake Optimizer has better performance in the optimization ability and convergence speed. The prediction accuracy of the model is also significantly improved under the dynamic non-stationary environment.

The Bucket Approach: Developing and Implementing an On-line Training Program in Tobacco Dependence Interventions Tailored for Behavioral Health Clinicians.

People coping with a mental illness and/or addictive disorders have a very high prevalence of smoking cigarettes. The Bucket Approach, a free online training, tailors evidence-based tobacco dependence interventions for behavioral health clinicians to increase the likelihood that they will also address the tobacco use of their patients. From October 2019 through August 2021, 999 people enrolled in and 447 people completed the training. Individuals who completed the training evaluated it highly with an overall mean score of 8.4 (scale = 1 for very poor to 10 for very good). 3- and 6-month follow-up surveys documented continued impact. The training resulted in substantial changes in beliefs about treating tobacco dependence. For example, before training, 18.3% of trainees strongly agreed with the statement, "The skills currently possessed by behavioral health clinicians can be easily applied to the treatment of tobacco dependence." This increased to 40.7% at the end of training.

Exploring the Efficacy of an Online Training Programme to Introduce Mental Health Recovery to Carers.

Family carers often support people with mental ill-health, however, there is a dearth of research on the importance of recovery to mental health carers. This article describes the delivery and qualitative evaluation of an online training programme on recovery to a group of eleven carers. The participants considered their understanding of the meaning of recovery, differentiating between its personal and clinical nature. They highlighted the importance of carer involvement in the service users' professional support, alongside the need for carers to participate more widely in service development. Finally, the participants found the training useful in enabling them to recognise their own needs in a caring journey, particularly valuing its delivery by a service user and carer trainer. This study is limited by the small number of participants in this programme; however, this series of connected studies suggests its potential to be rolled out more widely, possibly embedded in Recovery Colleges.

Effectiveness of an online training program for improving nurses' competencies in disaster risk management.

BACKGROUND: Nurses' incompetency in disaster risk management can have many negative consequences during disasters, so it is important to prepare nurses and improve their competencies in disaster risk management. This study was conducted with the aim of investigating the effectiveness of an online training program to improve competencies in disaster risk management. METHOD: This interventional study was conducted on nurses working in a specialized trauma hospital affiliated with the Kerman University of Medical Sciences in southeastern Iran in 2023. Eighty-one nurses were randomly assigned into two interventions (n = 42) and control groups (n = 39). The intervention group received an online training program in four sessions, and both groups electronically completed the demographic questionnaire and the nurses' perceptions of disaster core competencies scale (NPDCC) before and one month after the intervention. RESULTS: The study results showed no significant difference in disaster competency scores between the two groups before the intervention (p < 0.51), but the NPDCC score in the intervention group was statistically significant after the intervention compared to before the intervention (p < 0.02) and no statistically significant difference was observed between the two groups after the intervention (p < 0.16). CONCLUSION: While the online training program was found to significantly improve the NPDCC score of nurses in the intervention group, this increase was not significant when compared to the control group. Therefore, we suggest continuous practical exercises and maneuvers to improve nurses' perception of the competencies required for effective disaster management.

An Acceptance and Commitment Training (ACT) Framework for Teaching Cultural Humility: A Guide for Translating ACT from a Therapeutic Context into a Medical Education Curriculum.

The objective of this project was to train future physicians to work effectively and thoughtfully with diverse populations by teaching them to employ Acceptance and Commitment Training (ACT) skills to increase cultural humility, with the goal of improving attitudes, knowledge, and beliefs about working with diverse patients. We developed ACT for cultural humility online interactive modules as part of an elective course to teach Medical Spanish to 4th-year medical students. Pre- and post-pilot data pertaining to the cultural humility training modules on the Work-Related Acceptance and Action questionnaire, Multidimensional Cultural Humility Scale, knowledge, attitudes, and beliefs were analyzed using paired samples t-tests and Wilcoxon signed-rank tests. We also included descriptive data pertaining to overall satisfaction with the cultural humility modules and intent to apply the material learned to patient care. Our data showed a significant increase in the cultural humility of our participants as well as an increase in psychological flexibility, a higher favorability rating toward various ethnicities, improvements in attitude, and positive changes in beliefs and knowledge following completion of the modules. The modules were well received by the medical students, with high social validity ratings. The ACT for cultural humility curriculum has great potential to enhance medical education in diversity, equity, and inclusion by increasing both the understanding and the cultural humility of medical students and future professionals to work with diverse populations. The current paper provides a framework that can be used by other programs to shape the education of the future medical workforce to help promote culturally humble care.

Efficacy of online training at the International Mental Health Training Center Taiwan (IMHTCT): Pre and during the COVID-19 pandemic.

STUDY OBJECTIVES: The coronavirus disease 2019 (COVID-19) pandemic has resulted in major disruption to regular learning and training for medical staff. The aim of this study was to compare the learning efficacy between on-site training before the COVID-19 pandemic and online training during the pandemic for nurses, psychologists, social workers, and occupational therapists from Southeast Asia. METHOD: The current study derived data from the International Mental Health Training Center Taiwan (IMHTCT) from 2018 to 2020. IMHTCT Trainees Learning Effect Questionnaire (ITLEQ) scores of the medical staff and demographic variables were collected. Reliability and validity of the ITLEQ were estimated. The independent t-test was used to compare differences in ITLEQ scores between the pre-training and post-training stages among the trainees. In addition, generalized estimating equations were used to estimate the predictive effect of online training on changes in ITLEQ scores over time. FINDINGS: A total of 190 trainees were enrolled, including 92 social workers, 16 occupation therapists, 24 psychologists, and 58 nurses. The reliability and validity were satisfactory. The efficacy of the training programs at IMHTCT was significant for all of the healthcare workers. Furthermore, better training efficacy was found in the social workers and occupational therapists who received online training compared to those who received on-site training. The potential efficacy of online training was found in the nurses. CONCLUSION: Our results demonstrate the importance of online training for mental healthcare workers during the COVID-19 pandemic. Online training may be implemented into regular training courses in the future.

How Do Survivor and Mandatory Reporter Status Correlate with Program Outcomes for an Adult-Focused Child Sexual Abuse Prevention Program?

This exploratory study investigated group differences and pre-post changes in knowledge, beliefs, and behavior by mandatory reporters and Child Sexual Abuse (CSA) survivor status for a CSA prevention training designed for the general public. Of the 8,114 study participants, 32% identified as having experienced CSA, and 77% indicated they were mandatory reporters for child abuse and neglect. Mandatory reporters had higher baseline knowledge about CSA than those who were not mandatory reporters and reported more CSA preventative behaviors. Mandatory reporters continued to have higher levels of knowledge following the training. Survivors of CSA also had higher baseline knowledge about CSA and preventative behavior scores than individuals who are not survivors of CSA. Unlike mandatory reporters, they experienced fewer increases in knowledge. At posttest, there was no evidence of a difference in knowledge between CSA survivors and non-CSA survivors. For items related to beliefs, mandatory reporters had higher baseline scores than other participants. However, they had smaller gains, so mandatory reporters and non-mandatory reporters had more similar beliefs related to CSA after the training. There were few differences between CSA survivors and non-survivors on baseline beliefs related to CSA, though CSA survivors reported greater increases in beliefs that CSA prevention is their responsibility and in the idea that they know what to do to prevent CSA. These results have significant results for the development and evaluation of trauma-informed prevention programming.

Development, evaluation, and implementation of an online pain assessment training program for staff in rural long-term care facilities: a case series approach.

BACKGROUND: Pain among long-term care (LTC) residents, and especially residents with dementia, is often underassessed and this underassessment has been attributed, in part, to gaps in front-line staff education. Furthermore, although evidence-based clinical guidelines for pain assessment in LTC are available, pain assessment protocols are often inconsistently implemented and, when they are implemented, it is usually within urban LTC facilities located in large metropolitan centers. Implementation science methodologies are needed so that changes in pain assessment practices can be integrated in rural facilities. Thus, our purpose was to evaluate an online pain assessment training program and implement a standardized pain assessment protocol in rural LTC environments. METHODS: During the baseline and implementation periods, we obtained facility-wide pain-related quality indicators from seven rural LTC homes. Prior to implementing the protocol, front-line staff completed the online training program. Front-line staff also completed a set of self-report questionnaires and semi-structured interviews prior to and following completion of the online training program. RESULTS: Results indicated that knowledge about pain assessment significantly increased following completion of the online training program. Implementation of the standardized protocol resulted in more frequent pain assessments on admission and on a weekly basis, although improvements in the timeliness of follow-up assessments for those identified as having moderate to severe pain were not as consistent. Directed content analysis of semi-structured interviews revealed that the online training program and standardized protocol were well-received despite a few barriers to effective implementation. CONCLUSIONS: In conclusion, we demonstrated the feasibility of the remote delivery of an online training program and implementation of a standardized protocol to address the underassessment of pain in rural LTC facilities.

Web-based training intervention to increase physical activity level and improve health for adults with intellectual disability.

BACKGROUND: Individuals with intellectual disability (ID) are less physically active, have a higher body mass index (BMI) and are at greater risk for cardiovascular diseases (CVDs) than people without ID. The purpose of the study was to explore the effectiveness of a web-based training programme, consisting of 150 min of activity per week, on the health of people with ID. METHOD: Participants with ID living in supported accommodation (n = 28, 48% female, age = 36.4 ± 9.56 years) participated in a web-based training programme, consisting of a combination of exercises (endurance, strength balance and flexibility) of moderate intensity, 50 min, three times per week for 12 weeks. The body composition and waist circumference (WC) were measured, and questionnaires were used to assess enjoyment, quality of life (QoL) and physical activity (PA) level. Descriptive statistics and pairwise comparison pre and post intervention were carried out. RESULTS: A total of 22 out of 28 participants completed the 12-week training intervention with 83% mean attendance of training sessions. The intensity of the PA level increased and a decrease in fat mass of 1.9 ± 2.4 kg, P < 0.001 and WC of 3 ± 5 cm, P = 0.009 were observed. Enjoyment of training sessions was 3.9 out of 5, and no differences in QoL were found. CONCLUSION: A web-based training programme is an effective tool for improving health parameters of people with ID and offers a new way for caregivers to enhance the PA for the target group.

Prevention of partner violence: virtual case simulation for religious leaders of Korean American immigrant communities.

The project 'Religious Leaders for Healthy Families' aims to prevent intimate partner violence (IPV) and increase access to resources for immigrant victims by enhancing the capacity of religious leaders. Due to cultural and psychosocial barriers, immigrant women prefer to exhaust informal resources, including religious leaders, before seeking help from professional service providers. This study reports the development of a virtual case simulation in which Korean American (KA) religious leaders living in the USA practice how to prevent and address IPV in their congregation. Intervention mapping (IM) guided the development of the simulation. This process was informed by theory, research and expertise in prevention and virtual case simulation. We partnered with victim service organizations and received feedback from religious leaders. The simulation was pilot tested with nine KA religious leaders and three community leaders with IPV expertise in the KA community. The resulting intervention consists of 4 behavioral outcomes and 24 performance objectives. We identified the knowledge, attitudes, outcome expectations and self-efficacy needed to accomplish each objective. The most creative phase was the development of four modules, as interactive virtual case simulations, that address all performance objectives. IM and social cognitive theory provided a useful framework for developing this virtual case simulation. With culturally responsive modifications, the intervention has the potential to be adapted for religious leaders from other immigrant communities.

Religion can play a pivotal role in helping immigrant women. Religious institutions help immigrants maintain their ethnic identity and language and support their integration into the new culture. This study explains the development of an online intervention for Korean American religious leaders to prevent partner violence. Religious leaders in immigrant communities can play a significant role in perpetuating cultural norms that contribute to partner violence or, conversely, create norms that promote equity between partners and value seeking help. Partner violence is high in cultures that adhere to traditional gender roles, with male-dominated interactions, and perceive seeking help as a failure that would bring shame to the whole family. The intervention consists of four modules that depict interactions between a religious leader and female parishioners: (i) a deacon worried about a parishioner who might be a victim, (ii) an immigrant woman married to an abusive husband, (iii) a woman in the hospital because of multiple bruises and a broken arm and (iv) a graduate student concerned about her fiancé's behavior. Experts in various fields, community leaders in the prevention of partner violence, and religious leaders provided their feedback and expertise for program development.

SiamOT: An Improved Siamese Network with Online Training for Visual Tracking.

As a prevailing solution for visual tracking, Siamese networks manifest high performance via convolution neural networks and weight-sharing schemes. Most existing Siamese networks have adopted various offline training strategies to realize precise tracking by comparing the extracted target features with template features. However, their performances may degrade when dealing with unknown targets. The tracker is unable to learn background information through offline training, and it is susceptible to background interference, which finally leads to tracking failure. In this paper, we propose a twin-branch architecture (dubbed SiamOT) to mitigate the above problem in existing Siamese networks, wherein one branch is a classical Siamese network, and the other branch is an online training branch. Especially, the proposed online branch utilizes feature fusion and attention mechanism, which is able to capture and update both the target and the background information so as to refine the description of the target. Extensive experiments have been carried out on three mainstream benchmarks, along with an ablation study, to validate the effectiveness of SiamOT. It turns out that SiamOT achieves superior performance with stronger target discrimination abilities.

BepFAMN: A Method for Linear B-Cell Epitope Predictions Based on Fuzzy-ARTMAP Artificial Neural Network.

The public health system is extremely dependent on the use of vaccines to immunize the population from a series of infectious and dangerous diseases, preventing the system from collapsing and millions of people dying every year. However, to develop these vaccines and effectively monitor these diseases, it is necessary to use accurate diagnostic methods capable of identifying highly immunogenic regions within a given pathogenic protein. Existing experimental methods are expensive, time-consuming, and require arduous laboratory work, as they require the screening of a large number of potential candidate epitopes, making the methods extremely laborious, especially for application to larger microorganisms. In the last decades, researchers have developed in silico prediction methods, based on machine learning, to identify these markers, to drastically reduce the list of potential candidate epitopes for experimental tests, and, consequently, to reduce the laborious task associated with their mapping. Despite these efforts, the tools and methods still have low accuracy, slow diagnosis, and offline training. Thus, we develop a method to predict B-cell linear epitopes which are based on a Fuzzy-ARTMAP neural network architecture, called BepFAMN (B Epitope Prediction Fuzzy ARTMAP Artificial Neural Network). This was trained using a linear averaging scheme on 15 properties that include an amino acid ratio scale and a set of 14 physicochemical scales. The database used was obtained from the IEDB website, from which the amino acid sequences with the annotations of their positive and negative epitopes were taken. To train and validate the knowledge models, five-fold cross-validation and competition techniques were used. The BepiPred-2.0 database, an independent database, was used for the tests. In our experiment, the validation dataset reached sensitivity = 91.50%, specificity = 91.49%, accuracy = 91.49%, MCC = 0.83, and an area under the curve (AUC) ROC of approximately 0.9289. The result in the testing dataset achieves a significant improvement, with sensitivity = 81.87%, specificity = 74.75%, accuracy = 78.27%, MCC = 0.56, and AOC = 0.7831. These achieved values demonstrate that BepFAMN outperforms all other linear B-cell epitope prediction tools currently used. In addition, the architecture provides mechanisms for online training, which allow the user to find a new B-cell linear epitope, and to improve the model without need to re-train itself with the whole dataset. This fact contributes to a considerable reduction in the number of potential linear epitopes to be experimentally validated, reducing laboratory time and accelerating the development of diagnostic tests, vaccines, and immunotherapeutic approaches.

Effectiveness of the world's first 1-Day online hands-on laparoscopic suturing training during COVID-19 pandemic.

We aimed to investigate the effectiveness of an online laparoscopic suturing training course conducted via an online meeting program. The mean needle loading, stitching, and knot-tying times were 77.3 s, 63.0 s, and 140.3 s, respectively on the initial test. Total laparoscopic suture time before the course was 273.8 s. After the course, time measures across all parameters decreased significantly (p < .001). The mean needle loading, suture passing, and knot tying times were 25.0 s, 31.0 s, and 34.6 s on the final test. The total intracorporeal suture time after the course was 90.0 s. The Objective and Structured Assessment of Technical Skills Scores significantly increased from 16.8 at the initial test to 25.4 at the final test (p < .001).IMPACT STATEMENTWhat is already known on this subject? Training models like box trainers and virtual reality simulators have frequently been shown to significantly improve laparoscopic skills.What the results of this study add? A 1-day online laparoscopic suturing course significantly reduces the intracorporeal suturing time.What the implications are of these findings for clinical practice and/or further research? Basis the results, online laparoscopic suturing training might become the new norm for training over conventional training given the benefits of cost and time savings.
