Using complex systems to understand running-related injuries

ABSTRACT This study aims to investigate anthropometric and training characteristics associated with injuries in runners using a complex approach. We conducted a cross-sectional study with 97 Brazilian runners of both sexes (age: 39.1 ± 11.5 years; body mass index: 24.2 ± 4.2 kg/m2). A web survey was used for data collection, including age, sex, body weight, body height, training volume/frequency, session duration, running pace and injury information (yes or no; the number of injuries). The partial correlation parameter was used for network estimation, considering both sexes. For women, injury occurrence was positively and strongly associated with training frequency (r = 0.57) and the number of competitions (r = 0.64), while for men, a negative and strong association was found with age (r=-0.69), and positive associations were observed with BMI (r = 0.89) and training volume (r = 0.82). Network centrality showed that training session duration and the number of competitions/year presented a higher expected influence value for women (−1.47) and men (−1.31). Using a non-linear approach with Brazilian non-professional runners, training characteristics had a stronger influence on running-related injuries.

Identifying Factors That Might Affect Outcomes of Exercise-Based Therapies in Long-COVID

Background: Long-COVID, which might develop after a SARS-CoV-2 infection, is a rather new disease without standardized treatment strategies. A large number of approaches that integrate physical activity have been described in the literature, and this systematic review aims to examine changes in symptom severity, physical fitness, respiratory symptoms and quality of life during training and identify factors that might influence the respective outcomes. Methods: A literature search was conducted using the databases Pubmed, PEDro, BioMed Central, EBSCOhost, ProQuest and the ZBSport from 13 February 2024 to 27 February 2024, and 39 studies fulfilled the search criteria. Results: The analyzed study designs varied regarding the type of intervention (isolated vs. multidisciplinary), duration and intensity of training sessions and overall length of the program. Individualized holistic concepts of physical activity paralleled by additional approaches demonstrated high effectiveness. However, many of the participants continue to suffer from Long-COVID after the intervention. Conclusions: Long-COVID treatment should be individualized, multifactorial and not limited in time and should consider each patient’s pre-existing conditions and individual course of the disease to provide the best possible support and care.

Evaluation of tolerability and safety of transcranial electrical stimulation with gel particle electrodes in healthy subjects

BackgroundWith the advancement of transcranial electrical stimulation (tES) technology, an increasing number of stimulation devices and treatment protocols have emerged. However, safety and tolerability remain critical concerns before new strategies can be implemented. Particularly, the use of gel particle electrodes brings new challenges to the safety and tolerability of tES, which hinders its widespread adoption and further research.ObjectiveOur study utilized a specially designed and validated transcranial electrical stimulation stimulator along with preconfigured gel particle electrodes placed at F3 and F4 in the prefrontal lobes. We aimed to assess the tolerance and safety of these electrodes in healthy subjects by administering different durations and types of tES.MethodsEach participant underwent ten sessions of either transcranial direct current stimulation (tDCS) or transcranial alternating current stimulation (tACS), with session durations varying. In the experiment, we collected various measurement data from participants, including self-report questionnaire data and behavioral keystroke data. Tolerability was evaluated through adverse events (AEs), the relationship of adverse events with tES (AEs-rela), the Self-Rating Anxiety Scale (SAS), and the Visual Analog Mood Scale-Revised (VAMS-R). Safety was assessed using the Visual Analog Scale (VAS), the Skin Sensation Rating (SSR), Montreal Cognitive Assessment (MoCA), and Stroop task. These data were analyzed to determine the impact of different parameters on the tolerability and safety of tES.ResultsThere were no significant changes in the results of the MoCA and SAS scales before and after the experiment. However, significant differences were observed in VAS, SSR, AEs, and AEs-rela between tDCS and tACS. Additionally, fatigue increased, and energy levels decreased on VAMS-R with longer durations. No significant differences were found in other neuropsychological tests.ConclusionOur study revealed significant differences in tolerability and safety between tDCS and tACS, underscoring the importance of considering the stimulation type when evaluating these factors. Although tolerance and safety did not vary significantly across different stimulation durations in this study, future research may benefit from exploring shorter durations to further assess tolerability and safety efficiently.

CPAP delivered via a helmet interface in lightly sedated patients with moderate to severe ARDS: predictors of success outside the ICU

Objective: This study aimed to describe the outcomes and explore predictors of intubation and mortality in patients with ARDS due to COVID-19 treated with CPAP delivered via a helmet interface and light sedation. Methods: This was a retrospective cohort study involving patients with COVID-19-related ARDS who received CPAP using a helmet developed in Brazil (ELMOT), associated with a light sedation protocol in a pulmonology ward. Demographic, clinical, imaging, and laboratory data, as well as the duration and response to the ELMO-CPAP sessions, were analyzed. Results: The sample comprised 180 patients. The intubation avoidance rate was 72.8%. The lack of necessity for intubation was positively correlated with younger age, > 24-h continuous HELMET-CPAP use in the first session, < 75% pulmonary involvement on CT, and ROX index > 4.88 in the second hour. The overall in-hospital mortality rate was 18.9%, whereas those in the nonintubated and intubated groups were 3.0% and 61.2%, respectively. Advanced age increased the mortality risk by 2.8 times, escalating to 13 times post-intubation. Conclusions: ELMO-CPAP with light sedation in a pulmonology ward was successful in > 70% of patients with moderate to severe ARDS due to COVID-19. Younger age, pulmonary involvement, ROX index, and prolonged first Helmet-CPAP session duration were associated with no need for intubation. Older age and intubation are associated with mortality.

An interactive dashboard for analyzing user interaction patterns in the i2b2 clinical data warehouse.

Clinical data warehouses provide harmonized access to healthcare data for medical researchers. Informatics for Integrating Biology and the Bedside (i2b2) is a well-established open-source solution with the major benefit that data representations can be tailored to support specific use cases. These data representations can be defined and improved via an iterative approach together with domain experts and the medical researchers using the platform. To facilitate these discussions, it is important to understand how users interact with the system. The objective of this work was to develop metrics for describing user interactions with clinical data warehouses in general and i2b2 in particular. Moreover, we aimed to develop a dashboard featuring interactive visualizations that inform data engineers and data stewards about potential improvements. We first identified metrics for different data usage dimensions and extracted the relevant metadata about previous user queries from the i2b2 database schema for further analysis. We then implemented associated visualizations in Python and integrated the results into an interactive dashboard using Dash. The identified categories of metrics include frequency of use, session duration, and use of functionality and features. We created a dashboard that extends our local i2b2 data warehouse platform, focusing on the latter category, further broken down into the number of queries, frequently queried concepts, and query complexity. The implementation is available as open-source software. A range of metrics can be derived from metadata logged in the i2b2 database schema to provide data engineers and data stewards with a comprehensive understanding of how users interact with the platform. This can help to identify the strengths and limitations of specific instances of the platform for specific use cases and aid their iterative improvement.

FRAGMENTED THIGH INJURY: TREATMENT WITH PREBIOTICS, NANOPARTICLES, AND CELL THERAPY

The purpose of this study was to investigate the possibility of staged local treatment of an infected mine-explosive wound using a gel containing Bacillus spp., cerium oxide nanoparticles, and cell therapy. Object and Methods. The article presents a clinical case demonstrating the effective staged treatment of a 57-year-old patient with a fragmentary fracture of the right femur and a large purulent wound of the right thigh. The patient underwent Ex-fix rod-type femur-tibia stabilization and resection of a post-traumatic aneurysm of the right superficial femoral artery. In the first stage of treatment, two sessions of negative pressure wound therapy (NPWT) were applied, with pressures ranging from 75-115 mm Hg and a session duration of 4-5 days. In the second stage, local treatment involved a combination of antiseptics and probiotics (Bacillus spp.) alongside cerium oxide nanoparticles. By the 7th day, the eradication of pathogenic microflora was achieved, allowing for the third stage of treatment—application of autologous mesenchymal stem cells. Results: The treatment of combat trauma has become increasingly relevant in Ukraine and globally due to its complexity and the rising proportion of multiple and combined injuries, which account for 25-60% of cases. Infectious complications occur in 25% of combat trauma cases and are responsible for 70% of related deaths. Most structural and functional disorders associated with wound infections develop at the time of injury, intensify over time, and require immediate surgical intervention, improvements in local treatment methods, and new approaches for wound closure. Conclusions: The use of a combination of probiotics and NPWT therapy led to a rapid reduction of the inflammatory process. Clinical observations showed accelerated wound cleansing from fibrin and necrotic tissue. The combined treatment significantly reduced the size and depth of wound due to the formation of active pink granulation tissue (observed by days 8-9) and marginal epithelialization by days 10-13. During this period, no pathogenic flora were detected, allowing for the subsequent application of autologous mesenchymal stem cells. This treatment approach reduced the need for antibacterial drugs and prevented the need for additional surgical interventions. The inclusion of cerium oxide nanoparticles was an effective enhancement for cell transplantation, facilitating stem cell delivery and contributing to the treatment of large wounds.

Do Beliefs About Intelligence Drive Engagement in Online Learning?

This study investigates the relationship between students’ beliefs about intelligence (fixed vs. growth mindset) and their engagement and behaviour in an online learning platform. The data was collected from 28 students enrolled in COMP90082 – Software Project subject at The University of Melbourne. Students’ beliefs about intelligence were measured through a survey administered during the first week, while their online learning behaviours were captured through clickstream data from the learning management system. The study adopted a two-fold approach: first, students’ learning strategies were identified through cluster analysis of their online session duration. By examining over 41,000 learning actions —such as accessing course materials, participating in discussions, and completing assignments— three distinct learning strategies emerged: “light”, “light-intensive”, and “intensive.” Subsequently, the relationship between these learning strategies and students’ beliefs about intelligence was examined using data visualisation techniques, chi-square tests, and logistic regression models. The findings revealed that students with a growth mindset were more likely to adopt intensive and engaged learning approaches within the online platform. Conversely, those with a fixed mindset tended to exhibit lower engagement levels and less intensive learning strategies. The study may contribute to the growing literature on the psychology of online learning and highlight the potential for tailoring instructional interventions and platform design to foster a growth mindset, thereby enhancing student engagement and academic success in digital learning environments.

First clinical implementation of a highly efficient daily online adapted proton therapy (DAPT) workflow

Objective.This study presents the first clinical implementation of an efficient online daily adaptive proton therapy workflow (DAPT).Approach.The DAPT workflow includes apre-treatment phase,where atemplateand afallback planare optimized on the planning computed tomography (CT). In theonline phase, theadapted planis re-optimized on daily images from an in-room CT. Daily structures are rigidly propagated from the planning CT. Automated Quality Assurance (QA) involves geometric, sanity checks and an independent dose calculation from the machine files. Differences from the template plan are analyzed field-by-field, and clinical plan is assessed by reviewing the achieved clinical goals using a traffic light protocol. If the daily adapted plan fails any QA or clinical goals, the fallback plan is used. In theoffline phasethe delivered dose is recalculated from log-files onto the daily CT, and a gamma analysis is performed (3%/3 mm). The DAPT workflow has been applied to selected adult patients treated in rigid anatomy for the last serie of the treatment between October 2023 and April 2024.Main Results.DAPT treatment sessions averaged around 23 min [range: 15-30 min] and did not exceed the typical 30 minute time slot. Treatment adaptation, including QA and clinical plan assessment, averaged just under 7 min [range: 3:30-16 min] per fraction. All plans passed the online QAs steps. In the offline phase a good agreement with the log-files reconstructed dose was achieved (minimum gamma pass rate of 97.5%). The online adapted plan was delivered for >85% of the fractions. In 92% of total fractions, adapted plans exhibited improved individual dose metrics to the targets and/or organs at risk.Significance.This study demonstrates the successful implementation of an online daily DAPT workflow. Notably, the duration of a DAPT session did not exceed the time slot typically allocated for non-DAPT treatment. As far as we are aware, this is a first clinical implementation of daily online adaptive proton therapy.

Pilot Trial of a Speech-Language Pathology Telehealth Service to Enhance Postdischarge Dysphagia Care in Singapore.

Patients and caregivers in Singapore experience issues managing dysphagia care at home following hospital discharge, and they prioritized improving access to postdischarge dysphagia care and support. Hence, a postdischarge dysphagia telehealth service was developed. This study aimed to evaluate the feasibility of this service by examining patient and service outcomes, preliminary costs, and consumer satisfaction. Patients with dysphagia and their caregivers attended one or more telehealth sessions over the initial month post-hospital discharge. Reviews of dietary adherence and preparation, swallowing function, and therapy progress were conducted. If needed, clinical support and intervention were provided. Data related to patient and service outcomes, preliminary costs, and consumer satisfaction were collected and analyzed using descriptive statistics and content analysis. Twenty patients attended 42 telehealth sessions. No support was provided during 10 sessions, minor support was provided during 13 sessions, and major support and intervention were provided to address patient and swallowing safety during 19 sessions. Out of 20 patients, 19 required support and intervention during the first week postdischarge, but they experienced fewer issues with each subsequent session. They were highly satisfied with the service. The average session duration was 29.6 min. No sessions were cancelled. This service can be delivered with minimal additional health service resources and at a low cost to consumers. This service is feasible, cost-effective, and well accepted by consumers. It facilitates early identification and management of swallowing and patient safety during the initial month post-hospital discharge. Wider implementation of this service model should be considered. https://doi.org/10.23641/asha.27327345.

The Effect of Effort During a Resistance Exercise Session on Glycemic Control in Individuals Living With Prediabetes or Type 2 Diabetes: Protocol for a Crossover Randomized Controlled Trial.

Type 2 diabetes (T2D) is preceded by prediabetes, and these conditions place a great burden on patients and society. These conditions are significantly associated with poor glycemic control, which is improved by resistance exercise. It has been suggested that resistance exercise should be performed with a high degree of effort to improve glucose metabolism, but this is associated with negative psychological responses that might lead to lower long-term adherence. This study aimed to investigate the effect of the degree of effort during a resistance exercise session on glycemic control and psychological responses in individuals living with prediabetes or T2D. This study will be a crossover, 3-arm, randomized controlled trial. A total of 15 participants living with prediabetes or T2D will be thoroughly familiarized with 7 resistance exercises; afterward, they will perform 3 randomized experimental sessions, each lasting approximately 48 hours each, separated by at least 4 washout days. In 2 of these sessions, supervised resistance exercise will be performed, but the sessions will differ in the degree of effort in each set (high vs low) and will be equalized in terms of total weight lifted and session duration. For this, proximity to failure will be manipulated by changing the number of sets per exercise, the number of repetitions per set, and the resting interval between sets and exercises. Participants will also complete a sedentary (control) session, where they will not perform any exercise. In response to each session, psychological responses will be assessed (exertion, affect, enjoyment, self-efficacy, and discomfort). Glycemic control will be assessed by a continuous glucose monitoring device every 5 minutes, throughout the approximately 48 hours of each experimental session. Food and drink will be individually prescribed by a registered dietitian nutritionist and provided to participants, in order to control for the confounding effect of energy intake and diet composition. Physical activity levels will be assessed by accelerometry. Randomization will be done using the opaque, sequentially numbered envelopes technique. Participants and researchers will be blinded for continuous glucose monitoring and accelerometry data, and data will be analyzed by a blinded statistician. This study has been funded, and data collection is expected to take place between June 2024 and May 2025. Final manuscript submission should happen by August 2025. The results of this project might encourage individuals living with prediabetes and T2D to engage in resistance exercise while better informing exercise specialists on how to best incorporate resistance exercise in their client's or patient's routine.

Comparing 30 Versus 60min Cognitively Loaded Physical Exercise on Cognitive Function and Physical Health in Community-Dwelling Older Adults With Mild Cognitive Impairment: A Double-Blind Randomized Controlled Trial.

Mild cognitive impairment (MCI) is characterized by a mild decline in cognitive function and represents a risk stage for dementia in community-dwelling older adults. Exercise and dual-task training have been used to improve physical health, psychosocial health, and cognitive and learning functions in various subjects. However, the optimal time for these interventions has yet to be clearly identified. This study investigated the effects of cognitively loaded physical exercise (CLPE) on cognitive function and physical health in community-dwelling older adults with mild cognitive impairment and compared the differences according to exercise time. Fifty-one community-dwelling aged 60years or older with MCI were randomly assigned to 30-min CLPE (30CLPE, n=17), 60-min CLPE (60CLPE, n=17), and control (n=17) groups. The CLPE program consisted of a twice-weekly exercise program for 8weeks. During the exercise, a dual task was performed to assess cognitive load. The control group performed a typical exercise program at a dementia center during the same period. The Korean version of the Montreal Cognitive Assessment was used to evaluate cognitive function, and various physical health factors were assessed using the handgrip dynamometer and pinch gauge, Senior Fitness Test, dynamic and static balance abilities, and gait variables. After the intervention, both the 30CLPE and 60CLPE groups showed significant improvements in cognitive function, upper limb strength, senior fitness, balance, and gait (p<0.05), while the control group showed no significant changes in any of the variables (p>0.05). In between-group comparisons, both CLPE groups showed significantly improved cognitive and physical functions compared to the control group (p<0.05). However, there was no significant difference between the 30 CLPE and 60 CLPE groups (p>0.05). The results of this study demonstrate that cognitively loaded physical exercise is effective in improving cognitive and physical function in individuals with MCI. Both the 30-min and 60-min sessions resulted in significant improvements, with no statistically significant differences observed between the two durations. This suggests that persistence and consistency of exercise may be more important than the duration of individual sessions. Clinical Trials.gov: KCT0009053.

Artificial gravity: an effective countermeasure for microgravity-induced headward fluid shift?

Long-duration spaceflight is associated with pathophysiological changes in the intracranial compartment hypothetically linked to microgravity-induced headward fluid shift. This study aimed to determine whether daily artificial gravity (AG) sessions can mitigate these effects, supporting its application as a countermeasure to spaceflight. Twenty-four healthy adult volunteers (16 men) were exposed to 60 days of 6° head-down tilt bed rest (HDTBR) as a ground-based analog of chronic headward fluid shift. Subjects were divided equally into three groups: no AG (control), daily 30-min intermittent AG (iAG), and daily 30-min continuous (cAG). Internal carotid artery (ICA) stroke volume (ICASV), ICA resistive index (ICARI), ICA flow rate (ICAFR), aqueductal cerebral spinal fluid flow velocity (CSFV), and intracranial volumetrics were quantified at 3 T. MRI was performed at baseline, 14 and 52 days into HDTBR, and 3 days after HDTBR (recovery). A mixed model approach was used with intervention and time as the fixed effect factors and the subject as the random effect factor. Compared with baseline, HDTBR was characterized by expansion of lateral ventricular, white matter, gray matter, and brain + total intracranial cerebral spinal fluid volumes, increased CSFv, decreased ICASV, and decreased ICAFR by 52 days into HBTBR (All Ps < 0.05). ICARI was only increased 14 days into HDTBR (P < 0.05). Neither iAG nor cAG significantly affected measurements compared with HDTBR alone, indicating that 30 min of daily exposure was insufficient to mitigate the intracranial effects of headward fluid shift. Greater AG session exposure time, gravitational force, or both are suggested for future countermeasure research.NEW & NOTEWORTHY Brief exposure to continuous or intermittent artificial gravity via short-arm centrifugation was insufficient in mitigating the intracranial pathophysiological effects of the headward fluid shift simulated during head-down tilt bed rest (HDTBR). Our results suggest that greater centrifugation session duration, gravitational force, or both may be required to prevent the development of spaceflight-associated neuro-ocular syndrome and should be considered in future ground-based countermeasure studies.

Relation between wearable heart rate monitor derived training load and cardiac adaption in endurance athletes

Abstract Background No studies have effectively measured training load (TL) from wearable heart rate (HR) monitors and determined its relation to exercise induced left and right ventricular (LV, RV) remodeling. A better insight into drivers of exercise induced cardiac remodeling is of clinical relevance to guide training advice in athletes at risk of adverse remodeling. Purpose We determined the TL, based on HR monitoring by commercial wearables[1]. The number and duration of training sessions was quantified during a period of 3 months. Training-intensity was calculated as Edwards TRIMP (eTRIMP) based on the product of training duration in one of 5 HR zones (1=light, 5=very vigorous) and the coefficient related to the respective HR zone. Methods Training data was collected in 2 prospective multicenter studies. Master@Heart comprises endurance trained middle-aged men aged 45 to 70years[2]. Pro@Heart consists of elite athletes aged 16 to 23years[3]. For this analysis, all male athletes with complete training data recorded using a chest-worn HR monitor for 3 months were included. Using an in-house developed pipeline, maximal HR and TL were calculated from raw training data. Cardiac magnetic resonance imaging was performed to measure indexed LV/RV end-diastolic volume (LVEDVi, RVEDVi), end-systolic volume (LVESVi, RVESVi), ejection fraction (LVEF, RVEF) and LV mass (LVMi). Results Pro@Heart athletes (n=69; age 21.9 ± 4.2 years) trained more than Master@Heart athletes (n=82; age 55.2 ± 6.5 years) and their total 3-month TL (eTRIMP) was also higher (9718 ± 3190 vs. 5499 ± 3775min; P&amp;lt;0.05 and 22339 ± 7350 vs. 13438 ± 8880 AU; P&amp;lt; 0.05; Table 1). Considering all athletes, there was a strong correlation between both training duration and eTRIMP and LVEDVi, LVESVi, LVMi, RVEDVi and RVESVi. Training duration in zone 1&amp;2 correlated well with LVEDVi, LVESVi, LVSV, LVMi, RVEDVi and RVESVi (Table 2). We found small significant negative correlations between duration and eTRIMP compared to LVEF and RVEF (Table 2). To filter out individual training factors influencing cardiac remodeling we used a partial least squares method which included time and percentage of time spent in training zones and age. Accordingly, training duration in zone 1&amp;2 and age were the main predictors of cardiac volumes and LVMi. For LVEF, age and time in zone 3 was most predictive, whereas for RVEF zone 3 and to a lesser degree zone 1&amp;2 were the main predictors, irrespective of age. Interestingly, time spent in high intensity zones 4 and 5 was not predictive. Conclusion We prospectively quantified TL in comparison to CMR-derived measures of cardiac remodeling and demonstrated that training duration in low intensity training zones is most predictive for cardiac volumes and mass, whereas LVEF and RVEF are more closely associated to time in zone 3. Very vigorous intensity exercise was not predictive, likely due to limited time training in zone 4 and 5.

Surfing a culturally-relevant physical activity: a new wave for health promotion

Abstract Background Surfing originated with Native Hawaiians prior to Western contact. It has since gained worldwide popularity, with an estimated 50 million surfers globally, and recently became an official Olympic sport. Associations have been reported between surfing and mental and physical health outcomes, greater community cohesion, and stronger intra-family relationships. Despite this evidence, surfing is deeply understudied in the context of health promotion. Purpose Surfing was analyzed from a mixed methods perspective to explore factors associated with lifetime participation and current engagement, including gender, race/ethnicity, chronic disease, social context, meaning, and average time of participation. Methods Hawai’i adult residents (n = 1066) completed an online or phone questionnaire. Modified Poisson regression models were fit for lifetime engagement and having a self-reported chronic disease, adjusting for primary race/ethnicity, age, gender, and education. Results Over their lifetime, 42% of respondents (50% men and 37% women) had participated in surfing. Engagement was highest during youth and young adulthood, and decreased with age, yet trends varied notably by race/ethnicity, gender, and generation. Lifetime surfing engagement was significantly related to lower likelihood of diabetes (aPR:0.72; 95%CI:0.56-0.92;p=0.009). Individuals who regularly participated in surfing typically did so with friends (78%) or family (61%); average surfing session duration was 209 minutes. Qualitative results revealed the relevance of surfing across levels of influence for health and wellbeing from physical fitness to community, culture, history and spirituality. Conclusions This work provides insights on the health promotion opportunities of surfing across the life-course and populations, including disease prevention and management. This study has implications for planning and policy locally and globally to achieve optimal community and planetary health. Key messages • Surfing is not only a sport for elite athletes, but also an activity that can support community and individual health and wellbeing in many populations over the lifespan. • Promotion of surfing and public ocean access can support multidimensional influences for wellbeing and should be a focus of cross sector collaborations for optimal community and planetary health.

Assessment of digital literacy and user experience in patients with cochlear implants

Abstract Introduction The cochlear implant (CI) is the treatment of choice for people affected by deafness or profound hearing loss. Patients with cochlear implants (PwCIs) can enhance their hearing outcomes using digital hearing training programs (dHTPs). Current technological trends leans towards personalized, AI-driven dHTPs, aiming to optimize user experience (UX) and adherence. This study aims to investigate the digital literacy skills and UX of PwCI before and after testing a prototype of a dHTP with an AI-driven design (TraiCI). Methods Two research-specific questionnaires developed by the Hearing Center Düsseldorf (QDL and QUX) were used to assess digital literacy skills and user experience in TraiCI. Additionally, the User Experience Questionnaire (UEQ) was employed to evaluate general user experience. The UEQ assesses software quality across dimensions such as transparency and stimulation using paired opposites. Results 22 outpatient PwCIs the Hearing Center Düsseldorf with unilateral or bilateral CI (mean age 54 years; SD = 15) were included. In QDL, PmCI demonstrated high levels of digital literacy skills. The majority of PmCI (80.6%) reported prior experience with dHTP. Usage of these programs occurred daily to multiple times per week within the first six months after CI treatment, with session durations predominantly ranging from 10 to 30 minutes. QUX data indicated a smooth initiation process (70.8%) and seamless login experience (95.5%). The UEQ addressed various aspects of user experience, with ‘transparency’ receiving the highest scores (MW = 1.9; SD = 0.6), while ‘stimulation’ received the least positive ratings (MW = 0.0; SD = 2.1). Conclusions The results show a high degree of digital literacy among PwCIs. They encountered minimal challenges in operating hardware and software components. Further refinement is necessary to align with PwCI’s expectations and maximize benefits. Early and iterative involvement of PwCIs in future projects could optimize outcomes. Key messages • The study highlights the proficient digital literacy skills of cochlear implant patients (PwCIs). • Further refinement of dHTPs is needed to better align with PwCIs’ expectations and maximize benefits, emphasizing the importance of iterative involvement for optimized outcomes.

Relationship Between Training Frequency and Training Session Duration on Vitality in Recreational Runners: A Cross-Sectional Study

Background: Running can improve health status from a biopsychosocial perspective. However, isolation strategies, like the COVID-19 pandemic-induced lockdown, produce deleterious effects on both health status and sport performance. The aim of our study was to investigate recreational runners’ sporting habits, subjective vitality (SV), and well-being after the COVID-19 pandemic-induced lockdown. Methods: After data filtration, 5542 recreational runners (74.5% men and 25.5% women, &gt;18 years) were selected for further analyses. The participants answered preliminary questions regarding sporting habits and completed the validated Spanish version of the Subjective Vitality as a Dynamic Reflection of Well-Being questionnaire for assessing their SV after lockdown. Results: Subjective vitality scores did not differ between men and women, nor between age groups (p = 0.41 and p = 0.11, respectively). Subjective vitality was greater with weekly training frequency up to 5 days/week, where this enhancement plateaued, while average training session duration was positively related to SV, stabilizing at 91–120 min/session (p &lt; 0.001 for both). Conclusions: There is a dose–response relationship between both weekly training frequency and training session duration, and mental health benefits in recreational runners. Further longitudinal studies are needed in order to determine the optimal dose–response relationship for simultaneously enhancing mental health outcomes and running performance in recreational runners, especially regarding weekly training frequency, training session duration, and exercise intensity.

Assessing the Efficacy of Lokomat Training in Pediatric Physiotherapy for Cerebral Palsy: A Progress Evaluation.

Background: Gait disturbances in children with cerebral palsy can increase the hindrance caused by loss of independence and social engagement. The Lokomat, developed by Hocoma, shows promise as a supplementary tool for gait rehabilitation. This study investigates the impact of Lokomat training on gait parameters and trends observed during training. Methods: A total of 26 children (13 male individuals) with a diagnosis of cerebral palsy (CP), aged 4 to 23 years, were enrolled in the study. Patients participated in a standard comprehensive rehabilitation program with additional Lokomat training sessions. Gait function was assessed using the Timed Up and Go Test (TUG) and the 10 m walking test (10mWT) at the beginning and end of the rehabilitation period. Changes in Lokomat parameters (step number, session duration, speed, body weight support, and guidance force) were also analysed. Results: The median duration of the 10mWT and TUG significantly decreased across the groups after the treatment program. The highest increases were observed for the number of steps taken. Across the entire cohort, the linear trend curves for distance and number of steps exhibited near-perpendicular alignment with the horizontal axis, suggesting significant improvement in these parameters. A consistent trend was noted for speed, with the trend line aligned parallel with the horizontal axis. Decreasing trends were observed for body weight support and guidance force. Conclusions: Therapy with the Lokomat functioning as the active gait orthosis can be used as a form of support to the standard rehabilitation protocol for patients with CP.

Hyperbaric Oxygen Therapy (HBOT) in Moderate Traumatic Brain Injury (TBI): A Randomized Controlled Trial

Abstract Introduction Hyperbaric oxygen therapy (HBOT) is a novel technique recently under investigation with intention to improve outcomes in traumatic brain injury (TBI). It increases the partial pressure of oxygen in the blood and tissues by inhaling pure oxygen in an environment pressurized to at least 1.4 times normal atmospheric pressure (ATM) at sea level. The rationale behind the use of HBOT in TBI is its potential to mitigate the secondary brain injury cascade initiated by the primary mechanical trauma. Tissue damage and neuroinflammation secondary to intricate and complex cellular biochemical processes are expected to be counteracted by increased oxygen availability during HBOT, which reduces oxidative stress and improves neuroplasticity. Materials and Methods All patients, except whose legal guardians denied informed consent, with moderate TBI presenting to the neurotrauma center, All India Institute of Medical Sciences, Rishikesh, Uttarakhand, India, were included within the study period of June 2022 to July 2023. Patient allocation was randomized into two arms: namely, treatment and control arm. Simple randomization was done using randomization mobile app, RRApp. Each patient received standard of care per the Brain Trauma Foundation guidelines. Patients randomized under the treatment arm additionally received adjuvant HBOT sessions. One session daily for 10 consecutive days. Session duration was for 60 minutes each at 1.4 ATM. The primary objective of the study was to compare the Glasgow Coma Score (GCS) at discharge and 3-month post-TBI Glasgow Outcome Scale-Extended (GOS-E) among patients in the treatment arm (those who received adjuvant HBOT) with those in the control arm (those who received only standard of care). Results The mean GCS (±standard deviation [SD]) at discharge in the treatment arm was 14.37 (±00.51) with a median of 14 and a range of 14 to 15. Comparatively, the mean GCS (±SD) at discharge in the control arm was 13.40 (±00.84) with a median of 13 and a range of 12 to 15. The difference between the two arms was statistically significant (p &lt; 0.001). GOS-E at 3 months postinjury for the treatment arm was 7.62 ± 00.51 (mean ± SD) with a median of 8 (range: 7–8). For the control arm, GOS-E at 3 months postinjury was 6.40 ± 1.50 (mean ± SD) with a median of 7 (range: 4–8). The difference between the two arms was statistically significant (p &lt; 0.001). Conclusion The current study concludes that early adjuvant HBOT using 1.4 ATM with one session of one-hour daily for 10 days among adults sustaining moderate TBI significantly improves GCS at 10 days. Early adjuvant HBOT is also associated with significantly improved GOS-E at 3 months postinjury compared to standard of care alone.

Social Support and Quality of Life in Hemodialysis Patients: A Comparative Study with Healthy Controls

Background and Objectives: Hemodialysis patients face significant physical and psychological challenges, including diminished quality of life and reduced social support. This study aimed to assess the levels of social support and quality of life in hemodialysis patients and identify the sociodemographic and dialysis-related factors influencing these outcomes. Materials and Methods: This study included 115 hemodialysis patients and 107 healthy controls. Social support was measured using the Modified Social Support Survey (MSSS) and its abbreviated version (MSSS-5). Quality of life was assessed using the WHOQOL-BREF questionnaire. Demographic variables (age, sex, education, marital status) and dialysis-related factors (session duration, Kt/V, vascular access type, and urea reduction ratio) were analyzed to determine their effects on social support and quality of life. Results: Hemodialysis patients reported significantly lower scores in the Physical Health and Psychological Health domains of the WHOQOL-BREF compared to healthy controls. Males on hemodialysis scored lower than the controls in the Physical Health, Psychological Health, and Environment domains of the WHOQOL-BREF and the Affectionate Support and Positive Social Interaction subscales of MSSS. Conversely, hemodialysis females reported higher scores for Tangible Support, Emotional/Informational Support, and Affectionate Support. Longer dialysis sessions negatively impacted the Social Relationships domain. Married hemodialysis patients had higher Emotional/Informational Support and Affectionate Support scores. Conclusions: Hemodialysis patients experience diminished physical and psychological quality of life, particularly males. Social support, especially emotional and informational support, is crucial for hemodialysis patients, with marital status playing a key role. Addressing these psychosocial factors may improve outcomes for hemodialysis patients.

Harnessing Physical Training Resolve through the Modernization of Large-Scale Sports Venues in Selected Colleges in Henan Province, China

The results of this study highlight the relationship between the modernization of large-scale sports venues and the physical training resolve of students in selected universities in Henan Province, China. The findings indicate that while the modernization of sports facilities generally improved public accessibility and provided students with better infrastructure, it did not significantly influence all aspects of physical training resolve. There were significant correlations between public accessibility and students' motivation to participate in diverse sports activities, as well as between government-market dynamics and the duration of physical training sessions. However, areas such as social influence, peer support, and psychological constructs did not show strong associations with the modernization efforts. The study also found that the physical training resolve of students varied based on their course of study, with certain disciplines showing higher engagement in specific types of sports and psychological benefits. Overall, the results suggest that while modernization enhances some aspects of physical training, a more comprehensive approach is needed to fully support students’ physical engagement across all dimensions.
