The present study aims to explore and evaluate current practices among orthodontic specialists regarding the use of mini-implants, focusing on factors influencing usage decisions, experience in placement, perceptions of outcomes, and future perspectives of these devices in orthodontic practice. It seeks to explore the association between specialists' experience levels and their perceptions of mini implants, as well as the challenges encountered in their use. It is hypothesized that orthodontic specialists' perceptions and practices regarding the usage of mini implants are influenced by various factors, including their experience, training engagement, treatment outcomes, and preferences.Material and methodsThe study was conducted using an online, cross-sectional survey developed on the Survio platform to assess orthodontic specialists' perceptions of the clinical effectiveness and advantages of mini-implants in orthodontic treatments. The survey, consisting of 24 closed-ended questions in binary and multiple-choice formats, covered demographics, theoretical knowledge, clinical experience, and educational resources related to mini-implant use. Orthodontic specialists from Romania were invited to participate through the AREO association, and the survey was open for 12 weeks. Data collected from the survey were analyzed using descriptive statistics and multivariate logistic regression in SPSS software (Version 28), with a statistical significance threshold set at p &lt; 0.05.Resultsthrough a comprehensive analysis of survey data, the study investigates factors influencing specialists' perceptions, challenges encountered in practice, training engagement, material preferences, treatment outcomes, and indications for mini-implant usage. Notable correlations and discrepancies between documented literature and orthodontists' responses in Romania regarding mini-implant indications are explored, shedding light on the diversity of applications in orthodontic procedures highlighting the significance of education, training, and technical support in enhancing mini-implant utilization. Strategies to address barriers and promote informed decision-making among orthodontists are discussed.Conclusionsthe study reveals diverse preferences and utilization patterns regarding mini-implants across different orthodontic procedures, reflecting the versatility and adaptability of these devices in addressing various clinical needs. By comparing documented literature with real-world practices, the study identifies both correlations and discrepancies, providing valuable insights into the practical application of mini-implants in orthodontic treatments.

IntroductionThe increasing integration of digital tools in education highlights the potential of embodied pedagogical agents. This study investigates how task-related errors and language cues from a robot influence human perception, specifically examining their impact on anthropomorphism and subsequent empathy, and whether these perceptions affect persuasion.MethodsThirty-nine participants interacted with a NAO robot during a quiz. Employing a 3 × 2 mixed design, we manipulated the robot’s error rate (above average, human-like, below average) between subjects and language style (humble, dominant) within subjects. We measured perceived anthropomorphism, empathy, sympathy, and persuasion. Data were analyzed using multilevel modeling to assess the relationships between manipulated variables and outcomes.ResultsOur findings indicate that human-like error rates significantly increased perceived anthropomorphism in the robot, which in turn led to higher levels of empathy and sympathy towards it. However, perceived anthropomorphism did not directly influence persuasion. Furthermore, the manipulated language styles did not show a significant direct effect on perceived anthropomorphism, empathy, sympathy, or persuasion in the main experiment, despite pretest results indicating differences in perceived personality based on language cues.DiscussionThese results have important implications for the design of embodied pedagogical agents. While strategic implementation of human-like error rates can foster empathy and enhance the perception of humanness, this alone may not directly translate to greater persuasiveness. The study highlights the complex interplay between perceived competence, likability, and empathy in human-robot interaction, particularly within educational contexts. Future research should explore these dynamics further, utilizing larger samples, diverse robot designs, and immersive environments to better understand the nuances of how errors and communication styles shape learner engagement with pedagogical agents.

Published: January 2025

This study explores the impact of embodied experiences in Virtual Reality (VR) on individuals’ attitudes and behavior towards climate change. A total of 41 participants were divided into two groups: an embodied group that interacted with a virtual environment through full-body avatars, and a non-embodied group that observed the scenarios from an invisible observer’s point of view. The VR experience simulated the progressive consequences of climate change across three generations within a family, aiming to make the abstract and relatively distant concept of climate change a tangible and personal issue. The final scene presented an optimistic scenario of a future where humans had successfully combated climate change through collective action. The evidence suggests that there is an effect of the scenario on the carbon footprint response, even 6 weeks after the VR exposure, irrespective of condition. Additionally, increases were found in participants’ perceived influence on climate action and engagement in pro-environmental behaviors, with the embodied group showing a more pronounced response in the short term. These findings suggest that immersive VR experiences that incorporate virtual embodiment can be an effective tool in enhancing awareness and motivating pro-environmental behavior by providing a powerful and personal perspective on the impacts of climate change.

ObjectiveMuscle power is essential for the activities of daily living. Muscle power production depends on numerous factors such as muscle size and length, muscle architecture and fiber type and varies with age during growth. The association between muscle power output during a jump and lower limb muscle volume and length in adolescents is largely unknown. This study determined the relationships between muscle power developed during a countermovement jump with lower limb muscle volume and length in adolescents aged between 16 and 19 years.MethodsForty healthy adolescent males (n = 20) and females (n = 20) aged 16 to 19 years underwent a counter-movement jump (CMJ) test. Muscle power (MP) during the jump was calculated using the Gomez-Bruton equation. Lower limb muscle volume (MV) and length were calculated in both sexes using anthropometric methods. Pearson correlation was used to assess the associations between variables. Independent-sample t-tests were used to compare anthropometric and muscle performance data between males and females. Cohen's d was used to determine the size of the differences.ResultsThere were differences in all anthropometric variables between males and females (p &lt; 0.001). CMJ height (d = 4.45; p = 0.001) and MP (d = 4.74; p = 0.001) were greater in males than in females (p &lt; 0.001). These differences persisted when jump performance was normalized to the MV (d = 1.05; p = 0.01) and length (d = 4.07; p = 0.001). There were correlations between MV and MP for males and females, with a significant correlation between limb length and MP for males (r = 0.55; p = 0.002).ConclusionsThis study indicates that MV and length are associated with MP production during a CMJ in adolescents aged between 16 and 19 years, suggesting that these factors may be important determining factors for vertical jumping performance during adolescence. The sex-differences in jump performance variables persisted after normalization by MV and length, suggesting that MV and length did not entirely explain the sex difference in muscle power output during a CMJ.

Published: January 2025

BackgroundIt is assumed that the tennis serve is performed according to the kinetic chain principle in which a proximal-to-distal sequence in peak angular velocities of subsequent body segments can be observed to reach high end point ball velocities. The aim of the present study was to investigate if the magnitude and (intersegmental) timing of peak angular velocities of body segments in professional tennis players are different between first and second serves and if they are associated with serve performance.MethodsEight (two female and six male) professional tennis players performed each 48 tennis serves on a tennis court. Serve performances: Ball speed and accuracy were measured with a PlaySight system. Kinematics were assessed with a custom made high-end inertial measurement units (IMUs) system, sampled at 1,000 Hz. Magnitudes of, as well as the intersegmental timing between, three dimensional peak angular velocities of the pelvis, trunk, and dominant upper arm were analysed in relation to ball speed and accuracy with generalized estimating equations.ResultsPeak angular velocities of the pelvis, trunk and upper arm were significantly higher in the first compared to the second serve. The intersegmental timing did not show significant differences. Also, the intersegmental timing was not associated with the ball speed. Ball speed was significantly positively associated with peak angular velocities of the trunk and upper arm on both the first and second serve. Accuracy was positively associated with the peak trunk angular velocity and intersegmental timing between the pelvis and trunk in the first serve. Accuracy was negatively associated with peak trunk angular velocity in the second serve.ConclusionThe arm movement is important to produce high ball speed during a tennis serve. Additionally, the trunk, proximal to the upper arm in the kinetic chain, showed associations with ball speed. In contrast to the upper arm also with accuracy. Interestingly, professional players do not strictly follow a proximal-to-distal sequence. Intersegmental timing appears to be less important in the tennis serve compared to the segmental angular velocities, which were higher in the first compared to the second serve. Future research should investigate the uncovered role of the trunk in relation to tennis serve performance.

IntroductionLarge-scale sports events have a profound impact on the enhancement of residents' national identity. The study takes the Hangzhou Asian Games as an opportunity to investigate the influence of such events on national identity and the underlying factors.MethodsThe study takes the impact of residents' involvement in the Asian Games on their national identity as the research object, constructs a theoretical model with subjective well-being and city image as the mediator variables, randomly selects 1,096 residents by questionnaire survey, and analyzes their interrelationships as well as deeper influencing factors by using structural equation modeling and bootstrap.ResultsThe results show that the involvement of Hangzhou residents in the Asian Games has a significant positive impact on national identity, subjective well-being and city image (Estimate = 0.237/0.287/0.3). Furthermore, subjective well-being and city image have a significant positive impact on national identity (Estimate = 0.321/0.141), and city image has a significant positive effect on subjective well-being (Estimate = 0.264).DiscussionIt can be concluded that the degree of involvement in major sports events has a direct positive effect on national identity, and subjective well-being and city image play a partially mediating role in this effect. The results of the study provide a resident's perspective for assessing the impact of large-scale sports events, and provide elements that can be used as a reference for governments, city planners and event organizers to assess large-scale sports events.

Authors: Evrard Robin , Miri Othmane , Lacroix Valérie , Docquier Pierre-Louis , Schubert Thomas 
Published: January 2025

BackgroundRotationplasty, an invasive surgery, serves as an alternative to amputation in pediatric orthopedic oncology. It is currently applied in broader cases (e.g., infection, trauma, or malignant tumors). Winkelmann Type BII rotationplasty is a rare procedure with limited literature. Furthermore, no description of rotationplasties where the femur is attached to the sacroiliac joint has been published to date.MethodsBetween September 2022 and March 2023, three patients underwent Type BII rotationplasty. We used the Clavien-Dindo classification to describe postoperative complications and the musculoskeletal tumor society score (MSTS) for functional result assessments.ResultsOne patient suffered from multiple complications during the first 6 months postoperatively, one presented a single complication, and one had no complications after 4 and 3 months postoperatively, respectively. Two patients could walk pain-free with the help of crutches. One patient developed a crack on the femur, which did not require surgical revision. They all achieved satisfactory joint amplitudes of at least 50° in passive hip flexion. Unfortunately, one of the patients suffered from lung metastases.ConclusionsWinkelmann's Type BII rotationplasty is a reliable alternative to hindquarter amputation. Furthermore, we demonstrated that complete resection of the iliac wing and femur fixation through the sacroiliac joint is feasible.

Published: January 2025

BackgroundHuman brucellosis is the most common bacterial zoonosis worldwide, with brucella spondylitis (BS) being one of its most severe forms, potentially leading to spinal deformity or paralysis. This study aims to provide a comprehensive overview of the current status and research trends in the BS field using bibliometric methods.MethodsPublications on BS from January 1, 1980, to March 24, 2024, were retrieved from the Web of Science database. We used Biblioshiny, VOSviewer, Scimago Graphica, CiteSpace, and Microsoft Office Excel Professional Plus 2016 to analyze publication frequency, geographic distribution, institutional affiliations, international collaborations, authorship, journal sources, keyword usage, trends, and cited references.ResultsBetween January 1, 1980, and March 24, 2024, 197 publications on BS were analyzed. Turkey emerged as the leading contributor, with 62 publications, accounting for 31.47%. Weibin Sheng was the most prolific author, contributing 7 papers (3.55%). Xinjiang Medical University was the leading institution with 13 documents (6.60%). Medicine and Rheumatology International each published 6 papers (3.05%). CiteSpace analysis highlighted “spinal brucellosis,” “spondylitis,” “complications,” “diagnosis,” and “involvement” as the core research areas in BS. Keyword clustering analysis identified 11 primary clusters representing the main research directions. Analysis of abstracts and keyword trends revealed that post-2020, emerging research frontiers include “instrumentation,” “management,” and “debridement.”ConclusionThere has been significant progress in BS research, with a steady increase in publications. Current research focuses on diagnosis and complications, while future studies may explore management and instrumentation. Increased collaboration among countries and researchers is recommended.

Published: January 2025

ObjectiveDemonstrate the superiority of percutaneous balloon compression (PBC) in the treatment of primary trigeminal neuralgia (PTN) compared to trigeminal microvascular decompression (MVD).MethodsClinical data, including immediate, short-term, and long-term pain relief, complications, duration of the operation, and postoperative hospital stay, were retrospectively analyzed for 114 patients diagnosed with PTN who were treated with either PBC or MVD between January 2018 and December 2021.ResultsThere were no statistically significant differences observed in the pain relief rates between the two surgical methods at 24 h postoperatively (MVD: 91.07%, PBC: 96.55%), at 6 months postoperatively (MVD: 87.5%, PBC: 94.8%), at 1 year postoperatively (MVD: 83.90%, PBC: 94.80%), and at 2 years postoperatively (MVD: 78.60%, PBC: 72.40%). However, the incidence of meningitis following MVD was significantly higher than that following PBC (P &lt; 0.005). Additionally, both the duration of the operation and the length of the postoperative hospital stay in the MVD group were longer than those in the PBC group (P &lt; 0.005).ConclusionPBC demonstrates efficacy comparable to MVD while offering a simpler procedure, improved safety, and a shorter postoperative hospital stay. Therefore, it may serve as a viable alternative to MVD and could become the preferred surgical approach for treating PTN in the future.

Published: January 2025

IntroductionBovine coronavirus (BCoV) is an important pathogen of enteric and respiratory disease in cattle, resulting in huge economic losses to the beef and dairy industries worldwide. A specific and sensitive detection assay for BCoV is critical to the early-stage disease prevention and control.MethodsWe established a specific, sensitive, and stable assay for BCoV nucleic acid detection based on CRISPR/Cas13a combined with reverse transcription recombinase-aided amplification (RT-RAA) technology. The specific primers for RT-RAA and CRISPR RNA (crRNA) were designed in the conserved region of the BCoV nucleocapsid (N) gene.ResultsThe detection limit of the RT-RAA CRISPR/Cas13a assays for BCoV detection was 1.72 copies/μl, and there were no cross-reactions with the other 10 common bovine enteric and respiratory disease-associated pathogens. The coefficient of variations (CVs) of within and between batches were less than 4.98 and 4.58%, respectively. The RT-RAA-CRISPR/Cas13a assays work well in clinical samples of cattle and yak, the BCoV positive rate of 84 clinical samples detected by RT-RAA-CRISPR/Cas13a assays was 58.3% (49/84), it was notably higher than that of RT-qPCR (2.4%, 2/84; p &lt; 0.001). The 49 positive samples detected by RT-RAA-CRISPR/Cas13a assays were further confirmed as BCoV by Sanger sequencing.DiscussionA specific, sensitive, and stable assay based on RT-RAA-CRISPR/Cas13a assays for BCoV was developed, providing new technical support for the clinical detection and epidemiological monitoring of BCoV.

Published: January 2025

BackgroundIn chronic care, patient-GP collaboration is essential, but might be challenging if patients have complex health problems due to multimorbidity, psychosocial predicaments and addiction problems. To understand and manage these challenges, it is important to explore how patients’ and GPs’ attempt to collaborate, to maintain and achieve an alliance in order to gain good quality of care.AimTo explore how dyads of GPs and patients that GPs deem have complex health problems and difficulties following treatment perceive and manage challenges in their chronic care partnership.Design & settingA qualitative study from Danish general practice in deprived, rural areas.MethodSemi-structured interviews with 12 dyads of GPs and patients with doctor-assessed complex chronic conditions and difficulties following treatment. The principles of Systematic Text Condensation were used in the analysis.ResultsOverall, the patient-GP collaboration could be characterized as either stuck or unstable. In both types, the challenges were identified as pointless consultations, conflicts about lifestyle, resignation, concealment of information, and hopelessness. These challenges could be managed by solving conflicts, adjusting to the patient’s needs, accommodating the challenges in the relationship, and offering continued emotional support even with unsolved medical problems.ConclusionCare of patients with complex health problems may possess several challenges. In this study, patients and GPs experienced the relational dimension as crucial for collaboration. A robust therapeutic alliance, incorporating the patient’s agenda, offers an essential foundation for enhancing care in individuals with complex health problems.
