Objectives This study examines how the general characteristics major satisfaction, and positive psychological capital of pre-service early childhood teacher are related to simulated instruction anxiety, and confirms their rela-tive influence on simulated instruction anxiety. Methods The subjects of this study are 190 university student enrolled in departments related to childcare and early childhood education. Descriptive statistical analysis and correlation analysis were performed using SPSS program, and the relatiove influence of variables affecting simulated instruction anxiety was conformed through hierarchical multiple regression analysis. Results First, all sub-factors of the general characteristics, major satisfaction, and positive psychological capital of pre-service teachers’ showed a negative correlation with simulated instruction anxiety. Second, as a result of examining the relative influence on pre-service teacher’s simulated instruction anxiety, it was found that the in-fluence was in the order of self-efficacy, number of simulated instruction participation, and satisfaction with major subjects. Conclusions This study is significant in that it identified variables that affect pre-service teachers’ simulated in-struction anxiety in an academic reality where there is little actual research on simulated instruction anxiety. This study can be used as basic data for developing early childhood teacher training curriculum and programs.

Strengths and Difficulties Regarding Attention Deficit Hyperactivity Disorder: Correlation with Social Responsiveness and Disorder Severity

Objective: Children with neurodevelopmental disabilities often experience social difficulties. Children with attention deficit hyperactivity disorder (ADHD) are more likely to experience peer rejection and cognitive, academic, family, and professional difficulties. This investigation aimed to identify the predictors of difficulties faced by children and adolescents with ADHD. Material and Methods: We established ADHD diagnoses based on DSM-5 criteria. Moreover, every participant had a diagnostic evaluation by a child and adolescent psychiatrist using the Kiddie Schedule for Affective Disorders and Schizophrenia (K-SADS-PL) and a detailed sociodemographic form documented. Parents completed the Turgay DSM IV-Based Child and Adolescent Behavioural Disorders Screening and Rating Scale (T-DSM-IV-S), the Strengths and Difficulties Questionnaire (SDQ), and the Social Responsiveness Scale (SRS) for their children. Results: The study included 99 children, 59 in the ADHD group and 40 in the control group. There was no significant difference between the groups regarding gender and age. The mean scores of T-DSM-IV-S [Attention deficit (AD), Hyperactivity/impulsivity (H/I), Oppositional defiant disorder (ODD), Conduct disorder (CD)], SDQ, and SRS were significantly higher in the ADHD group than in the control group. Among the independent variables in the regression model, SRS total scores significantly predicted SDQ-total (β = 0.238, p = 0.033) and SDQ-emotion (β =0.439, p = 0.001) scores in the ADHD group. Conclusion: Children diagnosed with ADHD may have more receptive deficits in mutual interactions than their peers, which greatly impacts their social behaviors. Early social skills training for social functioning impairments may reduce the condition’s social impact

Visual training after central retinal loss limits structural white matter degradation: an MRI study

BackgroundMacular degeneration of the eye is a common cause of blindness and affects 8% of the worldwide human population. In adult cats with bilateral lesions of the central retina, we explored the possibility that motion perception training can limit the associated degradation of the visual system. We evaluated how visual training affects behavioral performance and white matter structure. Recently, we proposed (Kozak et al. in Transl Vis Sci Technol 10:9, 2021) a new motion-acuity test for low vision patients, enabling full visual field functional assessment through simultaneous perception of shape and motion. Here, we integrated this test as the last step of a 10-week motion-perception training.ResultsCats were divided into three groups: retinal-lesioned only and two trained groups, retinal-lesioned trained and control trained. The behavioral data revealed that trained cats with retinal lesions were superior in motion tasks, even when the difficulty relied only on acuity. 7 T-MRI scanning was done before and after lesioning at 5 different timepoints, followed by Fixel-Based and Fractional Anisotropy Analysis. In cats with retinal lesions, training resulted in a more localized and reduced percentage decrease in Fixel-Based Analysis metrics in the dLGN, caudate nucleus and hippocampus compared to untrained cats. In motion-sensitive area V5/PMLS, the significant decreases in fiber density were equally strong in retinal-lesioned untrained and trained cats, up to 40% in both groups. The only cortical area with Fractional Anisotropy values not affected by central retinal loss was area V5/PMLS. In other visual ROIs, the Fractional Anisotropy values increased over time in the untrained retinal lesioned group, whereas they decreased in the retinal lesioned trained group and remained at a similar level as in trained controls.ConclusionsOverall, our MRI results showed a stabilizing effect of motion training applied soon after central retinal loss induction on white matter structure. We propose that introducing early motion-acuity training for low vision patients, aimed at the intact and active retinal peripheries, may facilitate brain plasticity processes toward better vision.

Exploring Preclinical Medical Students' Experience Facilitating Group Dialectical Behavior Therapy (DBT) for a Student-Run Mental Health Clinic: A Qualitative Study.

This report explores the experiences of preclinical medical students who led group dialectical behavior therapy (DBT) for a student-run LGBTQ + mental health clinic. In the clinic, experienced clinicians trained and supervised preclinical medical students to facilitate DBT groups. The authors conducted a qualitative study to understand the impact of the DBT groups on the student facilitators via semi-structured interviews, which were evaluated using thematic analysis. The clinic hosted nine iterations of group DBT facilitated by preclinical medical students, involving 18 student leaders and 30 patients. Twelve student facilitators were interviewed. Participants had a diverse array of specialty interests and were primarily motivated by the opportunity for early clinical experience. They reported improved clinical skills, increased appreciation of psychotherapy as a treatment modality, and increased interest in incorporating psychotherapy in their future practice. Furthermore, participants reported using DBT skills to cultivate wellbeing during clerkship year and in their personal lives. Offering preclinical medical students the opportunity to lead group DBT therapy is a novel educational model providing early training in psychotherapy techniques. This opportunity for early direct patient experience in a supervised group setting attracted medical students with a diverse range of specialty interests. This model provided medical students specific DBT skills to implement in future patient care interactions and to maintain their personal wellbeing throughout medical training. The broad appeal and lasting effects of this program may prove beneficial at other institutions.

Early Communication Skills Training for Infants and Toddlers with Cochlear ImplantEarly Communication Skills Training for Infants and Toddlers with Cochlear Implant

Background and Aim: Early communication skills in children with hearing loss depend on the quantity and quality of information received from parents. The present study aimed to investigate the effectiveness of early communication skills training in developing the communication skills of infants and toddlers with cochlear implants. Methods: To this end, 54 infants and toddlers at the age range of 8–24 months with sever to profound hearing loss fitted by Cochlear Implant (CI) with their mothers participated in this study. The experimental and wait list control groups had auditory verbal therapy as the main intervention after the CI; however, the experimental group received a systematic early communication skills program. All subjects were assessed using the Communication and Symbolic Behaviour Scales Developmental Profile as the pre-and post-tests. Results: Multivariate analysis of covariance indicated the effect of systematic training on the early communication development of subjects in intervention group. Conclusion: Teaching the parents how to interact with infants and toddlers with CI could improve the communication skills of the infants and therefore it’s recommended to be included in the auditory rehabilitation programs.

Exoskeleton-assisted training to enhance lower limb motor recovery in subacute stroke: does timing matter? A pilot randomized trial

BackgroundLower limb motor recovery, including abnormal muscle synergies, occurs mainly within the first 5–8 weeks after a stroke. This suggests the importance of delivering impairment-focused therapies, such as therapeutic robots that promote symmetric gait, during this time-sensitive period, following the principle of “the earlier, the better.”ObjectiveFirst, to compare early robotic training (ERT) with usual care (UC) against UC alone on restoring intralimb muscle synergies and interlimb symmetry during functional tasks; Second, to investigate whether ERT is superior to delayed robotic training (DRT) starting after the proposed time-sensitive period.MethodsThis observer-blinded, randomized pilot trial with crossover design involved 19 nonambulatory adults included within 14 days poststroke. Those allocated to ERT (N = 10) received immediately 4 weeks of training (16 sessions, 4× /week) with the Ekso GT® above UC and were compared with the DRT group (N = 9) who received UC alone at this point. Thereafter a 3-week UC period followed to investigate sustainability of ERT and the interventional roles were exchanged; at about week 8 poststroke DRT subjects started the same experimental robotic protocol and ERT subjects continued UC as controls. Outcomes included changes in Fugl-Meyer lower extremity scores (FM-LE) reflecting muscle synergies, weight-bearing asymmetry (WBA), and dynamic control asymmetry (DCA) during quiet standing. Functional ambulation category (FAC) was used to classify walking independence (cut-off ≥4).ResultsA trend toward earlier reacquisition of walking independence favoring ERT with UC over UC was not accompanied by differences in FM-LE, WBA, or DCA (first objective). Thereafter, DRT with UC did not yield any significant changes relative to UC, such that no between-group differences were found favoring restorative effects of ERT over DRT (second objective).ConclusionThis pilot trial shows the feasibility of investigating a wearable exoskeleton as an adjunct therapy in subacute stroke. Nevertheless, our preliminary findings suggest that motor recovery of lower limb muscle synergies was not enhanced by 4 weeks of robotic training to reduce compensations with the less-affected side, irrespective of the timing of application.Trial registrationClinicalTrials.gov, identifier: NCT03727919.

Elimination disorders and associated factors among children and adolescents age 5–14 year-old attending paediatric outpatient clinic at Wolaita Sodo University comprehensive specialized hospital, South Ethiopia

BackgroundElimination disorder occurs in children over the age of normal toileting who continue to have an inability to control urination or feces, either during the day, at night, or both. Paediatric elimination disorders are not well understood by parents, teachers, medical professionals, mental health practitioners, and researchers. Hence, this study aimed to assess the magnitude of elimination disorder and associated factors among children and Adolescents aged 5–14 years old at Wolaita Sodo University Comprehensive Specialized Hospital, South Ethiopia, in 2022.MethodA hospital-based cross-sectional study was conducted from September 22 to November 22, 2022, at Wolaita Sodo University Comprehensive Specialized Hospital. A systematic random sampling technique was employed to select 423 study subjects. The data were gathered using a structured, face-to-face interviewer-administered questionnaire. The development of the symptom score for dysfunctional elimination syndrome of Vancouver questionnaires was used to screen for elimination disorders. Logistic regression model was used to determine the association between the outcome and independent variables. A 95% CI and Odds ratio with corresponding p-value < 0.05 were used to determine the predictors of the outcome variable.ResultThe overall magnitude of elimination disorder among children and Adolescents age 5–14 in this study was (n 70, 16.8%); in boys (n 47, 17.3%) and girls (n 23, 15.75%). The prevalence of enuresis was (n 64, 15.3%), encopresis (n 15, 3.6%), both enuresis and encopresis, or combined elimination disorder (n 9, 2.2%). Age 9–11 years (AOR = 3.2, 95%CI:1.09, 9.43), family size four and above (AOR = 3.4, 95%CI:1.78, 6.56), family history of elimination disorder (AOR = 3.9, 95%CI:2.12, 7.45), emotional problem (AOR = 2.2, 95%CI:1.18, 4.05), hyperactive problem (AOR = 3.8, 95%CI:1.83, 7.83), low toilet training skills (AOR = 5.9, 95%CI:2.61, 13.33), bad parenting practices, were poor supervision (AOR = 4.4, 95%CI 1.29, 14.69) were significantly associated with elimination disorder.Conclusion and recommendationIn this study, approximately one in five children and adolescents had an elimination disorder. Younger age, family size four and above, positive family history of elimination disorder, presence of emotional and hyperactive problems, bad parenting practices, and low toilet training skills were factors associated with elimination disorders. Therefore, preventative, etiological, and therapeutic measure, early toilet training, supportive parenting practices, screening for children’s and adolescents’ behavioral problems, and elimination disorders need attention to reduce the effect of the problem.

Increasing confidence in mentoring strategies for predoctoral and postdoctoral scholars through implementation of a mentoring academy

In support of the development of undergraduate researchers and the mentor development of predoctoral and postdoctoral scholars (Near Peers), a targeted near peer mentor training program was developed. Innovative and highly impactful early training experiences in research play a key role to inspire and motivate the next generation of scientists. Predoctoral and postdoctoral trainees are often asked to assist in the training and mentoring of short-term summer undergraduate researchers. Previous studies have shown that the efforts of these “near peers” to educate, train, and develop the summer undergraduate scholars have a positive impact on the undergraduate researchers. However, many near peer mentors have limited mentor training/experience and lack confidence in their ability to mentor undergraduate scholars. Thus, developing avenues and opportunities to train near peers on mentoring is vital to enhancing the experience of both the undergraduate researchers and near peers. The Kidney Undergraduate Research Experience (KURE) at the University of Alabama at Birmingham (UAB) engages undergraduate summer scholars with a wholistic research experience which includes an involved team of near peer mentors. A near peer mentor training program was developed with input from near peer focus groups, based on their interest in expanding their mentoring abilities and developing confidence in their role as a near peer mentor. The aim of this study was to determine whether this mentoring program was effective in increasing near peer mentoring abilities and confidence levels through quantitative and qualitative measures. Evaluations were given to near peers prior to, during, and at the end of the 6-month program (44 scholars started the program in Fall 2022 and 33 scholars completed all activities). We found that 83% of near peers expressed increased confidence in mentoring (n=24). Improvement in specific mentoring abilities were also assessed, such as “confidence in effectively communicating expectations” (pre- 4.02, ±0.82, n=44; post- 4.83 ±0.37, n=24; using a scale from 1 = not at all to 5 = very confident). We also identified the most impactful elements of the program including facilitation, topics, and platforms. Through assessing these aspects of the program, we determined essential and sustainable elements for future near peer mentor training programs. We conclude that a near peer mentor training program builds confidence and enhances the ability of predoctoral and postdoctoral scholars in their roles as near peer mentors. NIH R25DK115353 — 05S1.

An efficient training-from-scratch framework with BN-based structural compressor

Channel pruning is an effective way of compressing convolutional neural networks (CNNs) under constrained resources. The current pruning methods follow a progressive pretrain-prune-finetune pipeline, which is inefficient and computationally expensive. In this paper, we bypass the pretrain-prune-finetune pipeline and propose a novel and efficient model training framework based on online channel pruning, which automatically produces a compact well-performed sub-network in one training-from-scratch pass under a given budget condition. Specifically, we introduce a novel BN-based indicator and a sparsity regularization strategy in the early training stage to iteratively and greedily shrink the model layers, which encourages a high-quality architecture with low channel redundancy. To ensure training stability and promote the generalization ability of the resultant pruned network, we also skillfully incorporate a simple self-distillation framework into our training and pruning pipeline. Extensive experiments indicate that our method can effectively achieve competitive performance on the image classification task compared with the state-of-the-arts.

Survey on the Patterns of Feeding Difficulties and Behaviors in Filipino Children with Autism Spectrum Disorder Seen in a Philippine Tertiary Hospital and the Impact of the COVID-19 Pandemic.

To describe patterns of feeding difficulties and behaviors of Filipino children diagnosed with Autism Spectrum Disorder (ASD). An electronic mealtime survey was administered to caregivers of 3- to 9-year-old children diagnosed with ASD in a Philippine tertiary government hospital. Descriptive statistics and correlation analyses between feeding difficulties measured as Mealtime Survey Score, sociodemographic data, and early feeding history were performed. The impact of the COVID-19 pandemic to these was analyzed through a binomial test. All of the 115 study subjects reported at least one problematic feeding behavior, with picky eating being the most frequent (61.74%). Significantly, more feeding difficulties were observed among the children with reported early feeding difficulties during their 2nd and 3rd year of life. There were no documented statistically significant changes in feeding behaviors during the past six months of the COVID-19 pandemic. There is a high prevalence of feeding difficulties and problematic feeding behavior among Filipino children with ASD, however no significant changes to these during the past six months of the COVID-19 pandemic were documented. Present feeding difficulties and behaviors were associated with history of early feeding difficulties, highlighting the need to include feeding difficulties in screening tools, and early training programs and interventions for children with ASD.

NOT LOSING ONE CM OF MUSCLE CIRCUMFERENCE DURING EXTENSIVE BONE LENGTHENING: A PACT WITH THE DEVIL OR THE ANGELS?

IntroductionA 6cm femoral gain requires 5-Y during normal growth, but only 6–8-W surgically (x30–40 faster). In lengthening surgery, losses of muscle force (MF) and circumferences (MC) are major. Recovery is long, preventing sports till bone fusion.Can we maintain MC and strength throughout the entire lengthening and how?We monitored for over 30 years patients for muscle force (isokinetic), circumferences, activities (including sports) and food intake, and acted on the 5 principles of the Osteostasis.Materials &amp; MethodsOver 750 femoral lengthening with Full WB Nails (FWBN) got Isokinetic testing (≧1991), circumferences measurements (≧2012; 20-15-10-5-0cm above patella, max-calf, mini/max-ankle), food intake (≧2012), using MyFitnessPal App (≧2016), gradually enforced. Preoperative training along with a daily post-operative training are supervised by our trainers. Recommendations for food intake and activities were provided. Patients noted on a specific App all parameters. Compliance was noted.ResultsInstead of a traditional 7–9cm circumference loss for 8–10cm gains using Ex-fix or nails, with FWBN and our protocols, no MC loss could be noted in compliant pre-trained patients, intensive early post-op resistance training, high calory intake (M:&gt;4200, F:&gt;3000; 20–25% Proteins) and supplements (no fat pad increase). Bone fusion could be obtained at the end of lengthening or within short weeks (Healing Index down to 8D/cm)Non-compliant patients (or using morphine), lost weight and MC.ConclusionsIncreasing by 8–10cm muscle length, even bilaterally, and maintaining MC during lengthening, is possible, with very fast bone fusion. It requires building up several hundred of grams of muscles.The ‘building up equation’ associating resistance bike from the early post-operative phase with sports, strong food intake with increased protein intake, and added supplements with no morphine medication, proved to boost circumferences and bone fusion. It induced fast recovery, walking and sports capacities.

Possible Connection between the Development of Executive Functions and Music Education According to the Kodály Concept

This research will focus on comparing tasks that are used to measure the development of executive functions (EFs) and musicianship exercises according to the Kodály concept in order to find analogies and functional intersections between them. EFs are essential for our mental and physical health, for school and job success. Since these skills can be improved and early EFs training might help reduce social disparities in academic achievement and health, pinpointing activities that could develop EFs has become an important research topic in psychology, neuroscience, and education in recent years. The main direction of this research will be a close examination of the tasks used for measuring the three core components of EFs - inhibition, cognitive flexibility and working memory alongside musicianship exercises taken from Kodály methodological books and lesson observations that work in a similar way. This study has found similarities between EF tasks and Kodály musicianship exercises in all the three core components of EFs. These findings could indicate that with Kodály’s music education approach we are not only practising musicianship exercises but we might challenge our EF skills as well. This research, therefore, could be a first step that leads to a more complex investigation into the potential positive impact of music education according to the Kodály Concept on EFs.

Feasibility of Combining Functional Mobilisation with Resistance and Endurance Training for Mechanically Ventilated Patients in Intensive Care Unit Setting-A Pilot Study.

Background: Intensive-care-acquired weakness resulting in functional impairment is common in critical care survivors. This study aims to evaluate the feasibility of a combined early functional training with endurance and resistance training and its effect on the functional outcome. Methods: It is a pilot study performed in a 39-bed Medical and Surgical Intensive Care Unit (ICU). Patients who were premorbidly independent and were mechanically ventilated for ≥24 h were recruited to receive functional mobilisation (sit out of bed, ambulation), endurance (bed cycling), and resistance training (selected upper and lower limb muscle training using weights). The primary outcomes were feasibility of training, muscle strength, handgrip strength, quadricep strength, and Functional Status Score-Intensive Care Unit (FSS-ICU) collected at the first assessment in the ICU, at the ICU discharge, and at hospital discharge. Secondary outcomes were functional capacity (6-Minute Walk Distance) and quality of life measures, EQ-5D, at hospital discharge and at 3 months. Results: Out of the 11 patients, 6 (54.54%) patients achieved level 2 functional mobilisation, 2 (18.18%) patients achieved level 2 resistance training, and 1 (9.09%) patient achieved level 2 endurance training. There were no significant differences in the medical research council (MRC) score, quadricep strength, and handgrip strength between the first assessment in the ICU, at the ICU discharge, and at hospital discharge. However, there was a significant difference in FSS_ICU (p < 0.008) from the first assessment in the ICU up to hospital discharge. EQ-5D visual analogue scale also showed a change of 8.5% at 3-month follow-up. 6MWD showed significant difference (p < 0.043) at 3-month follow-up compared to that at hospital discharge. Conclusions: The study found low compliance to resistance and endurance training in patients with mechanical ventilation. However, functional mobilisation in terms of sit out of bed was possible in more than half of the recruited patients.

Sink or Swim? Sleep Patterns in Highly Trained Adolescent Swimmers during the In-Season Phase of Training

Abstract Objectives The aim of this study was to investigate the sleeping patterns of highly-trained adolescent swimmers. Further objectives were to compare subjective and objective measures of sleep and to evaluate the relationship between electronic device use and sleep in this cohort. Methods Fifteen national-level swimmers (age: 16.4 ± 1.0 years) wore wrist actigraphs while completing sleep diaries over a two-week training period. Types of nights were classified as early morning training (≤7am - EARLY), day training (&gt;7am - DAY), and no training (REST). Information on electronic device use before bed and other sleep behaviors was collected via questionnaires. Results Total sleep time (TST) was significantly (p &lt; 0.05) shorter on nights preceding EARLY (5:53 ± 1:06 hour:min) compared with nights preceding DAY (7:40 ± 1:12 hour:min) and REST (7:59 ± 1:19 hour:min). Participants overestimated subjective TST by ∼54 minutes when compared with objectively measured TST (p &lt; 0.05). Discussion Adolescent athletes obtained a greater amount of sleep prior to later training the next day or before rest days, when compared with early morning swim training the next day. Adolescents also overestimated their sleep duration by ∼1 hour per night. There were no significant relationships between electronic device use at night and measured sleep indices.

Principal Component Networks: Utilizing Low-Rank Activation Structure to Reduce Parameters Early in Training

Recent works show that overparameterized neural networks contain small subnetworks that exhibit comparable accuracy to the full model when trained in isolation. These results highlight the potential to reduce the computational costs of deep neural network training without sacrificing generalization performance. Initial approaches for finding these small networks relied on expensive multi-round train-and-prune procedures, limiting their practical potential, but more recent work identifies subnetworks using structured pruning techniques early in training. In this article, we study network activations, rather than network weights, and find that hidden layer activations in overparameterized networks exist primarily in subspaces smaller than the actual model width. We further notice that these subspaces can be identified early in training. Based on these observations, we show how to efficiently find small networks that exhibit similar accuracy to their overparameterized counterparts after only a few training epochs. We term these network architectures Principal Component Networks (PCNs). PCNs compress individual layers by retaining only the high variance linear combinations of channels—defined by the principal components of the layer inputs—a key difference from structured pruning techniques which focus on individual channel pruning using localized channel measurements. We evaluate PCNs on CIFAR-10 and ImageNet for VGG and ResNet style architectures and compare against existing methods for subnetwork identification during early training. We find that PCNs consistently reduce parameter counts with little accuracy loss, thus providing the potential to reduce the computational costs of deep neural network training. Beyond model compression, we also connect our observation regarding hidden layer activations to the feature representations learned by neural networks and discuss areas for future work.

Perception, Knowledge, Indications, and Future Prospects of Point-of-Care Ultrasound Among Medical Students in Saudi Arabia.

Introduction Point-of-care ultrasound (POCUS) has become integral across medical specialties globally, addressing clinical queries, guiding procedures, and bridging the gap between physical examination and advanced imaging. Early ultrasound training for medical students enhances clinical decision-making and reduces diagnostic errors. Aims To evaluate the knowledge and attitude of senior medical students towards POCUS and to assess knowledge gaps and difficulties encountered by senior medical students to assist in the development of future curricula. Methodology This is an observational, cross-sectional approach to evaluate knowledge, attitude, and practice ofPOCUSamong senior medical students in the Kingdom of Saudi Arabia. The study was conducted from January to September 2023. An electronic questionnaire was distributed through online platforms utilizing medical school databases across various regions. The survey encompassed sociodemographics, training methods, diagnostic indications, and participants' self-reported proficiency and attitudes toward POCUS. The data was chiefly collected using the Likert scale. Descriptive statisticswere used to describe the quantitative and categorical variables. Bivariate and multivariate analyses were used to examine correlations. Results A total of 359 senior medical students completed the survey. Most responders were females (57.9%) with the predominating age group being ≤ 24 years (83.6%). The students predominantly were from the Central region of Saudi Arabia (75.5%). Ultrasound training varied among responders; 31.5% received formal courses (median duration: two hours) and 23.4% informal courses (median duration: four hours). Around 17.3% practiced POCUS self-teaching (median duration: four hours). A total of 3.6% had formal POCUS accreditation. A gargantuan 82.2% never used POCUS in their attached hospital for a variety of reasons.Multivariable logistic binary regression analysis showed a positive correlationbetween students' self-teaching of POCUS and their perceived difficulty performing an ultrasound examination for patients in daily practice. Discussion A comparable study was done at King Saud binAbdulazizUniversity for Health Sciences (KSAU-HS) in 2022 surveying 229 senior medical students byRajendramet al. In their study, 21.4% completed formal courses and 12.7% took informal courses. While many students in our study were not exposed to POCUS (82.2%), KSAU-HS reported a higher percentage reaching 94.8%. A study by Russel et al. demonstrated more than half of 154 surveyed medical schools in the United States have implemented POCUS into their students' curriculum. Conclusion POCUS stands as a valuable skill that can enhance the educational journey of undergraduate medical students. Considering that a significant number of participants haven't yet taken formal medical school courses suggests a lack of awareness about its significance in the medical field. Offering additional courses with practical components could enhance the proficiency, confidence, and outlook of medical students toward POCUS.

LITERATUR REVIEW: PENCEGAHAN CEDERA DAN REHABILITASI PADA PELARI TRAIL

Trail running is sports activity that combines two activities, namely mountain climbing and running. Trail running activities are carried out on mountains that have tracks in the form of paths, in the form of ground stones, or a mixture of sand and small rocks. Trail running was first carried out in the United States of America and continues to develop in Indonesia for example Bandung, Probolinggo, Lombok dan Banyuwangi, Which have been associated in the form of ITRA (International Trail Running Association). The majority of trail running injuries occur in the lower legs, especially the knees and ankles. The main mechanisms underlying injury and injury development include inadequate neuromotor control-balance-coordination ,running through fatigue and abnormal kinematics on a variety of terrain. Pre-Rehabilitation programs such as strengthening the kinetic chain consisting of dynamic flexibility, neuromotor strength and balance, plyometrics exercises can encourage stable and also controlled movement on trails. Educating patients about symptoms of early musculoskeletal soreness and training adjustments also proved to help prevent injuries from developing into serious overuse injuries. Regarding to the increasing number of the injury in trail runners, this article was wrote to describe the role of injury prevention and safe training to reduce the risk of injury and also early rehabilitation program for the injured runners. Study by Vincent et all that review the injury prevention, safe training and rehabilitation to return to sport was the main source in the discussion. The review result showed that educating the runners to prevent injury and how to do the safe running shown a positive impact to reduce the numbers of injury. Early rehabilitation program also shown a good impact in promoting healing in injured runners.

DN-DETR: Accelerate DETR Training by Introducing Query DeNoising.

We present in this paper a novel denoising training method to speed up DETR (DEtection TRansformer) training and offer a deepened understanding of the slow convergence issue of DETR-like methods. We show that the slow convergence results from the instability of bipartite graph matching which causes inconsistent optimization goals in early training stages. To address this issue, except for the Hungarian loss, our method additionally feeds GT bounding boxes with noises into the Transformer decoder and trains the model to reconstruct the original boxes, which effectively reduces the bipartite graph matching difficulty and leads to faster convergence. Our method is universal and can be easily plugged into any DETR-like method by adding dozens of lines of code to achieve a remarkable improvement. As a result, our DN-DETR results in a remarkable improvement ( +1.9AP) under the same setting and achieves 46.0 AP and 49.5 AP trained for 12 and 50 epochs with the ResNet-50 backbone. Compared with the baseline under the same setting, DN-DETR achieves comparable performance with 50% training epochs. We also demonstrate the effectiveness of denoising training in CNN-based detectors (Faster R-CNN), segmentation models (Mask2Former, Mask DINO), and more DETR-based models (DETR, Anchor DETR, Deformable DETR).

Online psychotherapy as a first clinical experience during the Covid-19 pandemic: A new generation of psychotherapists in the digital age

The temporary closure of the Outpatient Psychotherapy Clinic at the Sigmund Freud Private University in Vienna during the Covid-19 pandemic demanded an immediate and unexpected reaction to assure further psychotherapeutic services. Both psychotherapists and patients were forced into a rapid transition to online psychotherapy. While Covid-19 research has comprehensively described challenges of online psychotherapies, we were interested in learning specifically how early stage psychotherapists-in-training, who started their clinical work with patients exclusively in the online setting, experienced this unprecedented clinical situation.Sixteen in-depth interviews were conducted with psychotherapists in training. The data were analyzed using a thematic analysis. The analysis revealed how psychotherapists in training were able to cultivate a set of early-training resources and competencies in the online therapy setting without evidence-based guidelines from supervisors and the institution. This study highlighted the necessity of incorporating specific and novel educational input that is necessary for achieving specific online skills in the early training phase. Recognizing that the therapeutic landscape has undergone an irreversible transformation, the data suggest that distinct techniques are necessary to equip early-training psychotherapists for the now commonly practiced alternation between online setting and in-person setting in psychotherapeutic processes.
