Background: There is a small number of questionnaires for children in the international literature that assess back care knowledge and spine disease prevention. A back care knowledge questionnaire in Hungarian for 14–17-year-old children is not yet available. This study aimed to translate and adapt the back care knowledge questionnaire published by Monfort et al. into the Hungarian language and to examine its reliability and validity in assessing the back care knowledge of 14–17-year-old children. Methods: This cross-sectional study included 253 (134 girls and 119 boys) adolescents, with a mean age of 14.84 (14–17) years. The questionnaire adaptation was performed according to Beaton’s six-step principle. To test its internal consistency, the Kuder–Richardson 20 formula, containing binary variables, was used to assess the reliability of the questionnaire. The test–retest reliability was examined by the intraclass correlation coefficient (ICC). SPSS 27.0 software was used for data analysis, and the results were considered significant at p < 0.05. Results: The internal consistency measured by the Kuder–Richardson 20 coefficient examining the reliability of the questionnaire was 0.514. The test–retest reliability measured by intraclass correlation coefficients was 0.992 (0.985–0.996) p < 0.001. According to the Health Questionnaire on Back Care Knowledge and Spine Disease Prevention for 14–17-year-old children, the level of back care knowledge was 57.2%. Conclusions: The back care knowledge of Hungarian children is around 57.2%, which is lower than the data published in the international literature (60–70%). The Hungarian version of the questionnaire assessing the back care knowledge of 14–17-year-old children, the “Health Questionnaire on Back Care Knowledge and Spine Disease Prevention for 14–17 years old children (HEQBACK-14–17)”, was found to be a suitable back care knowledge measuring tool among 14–17-year-olds; however, the development or adaptation of more measurement tools is needed for better understanding and more precise examination.

Coding and computational thinking (CT) are important skills to include in early childhood education. Measuring these vital skills in preschool-age children can be challenging. We modified the TechCheck-PreK assessment, an unplugged measure of CT for 3-to-5-year-old children, to increase reliability and to add foundational coding concepts. We created the Coding Readiness Assessment (CRA) from a subset of nine TechCheck-PreK items and twelve new items that assess additional CT and coding readiness constructs. In an initial feasibility study of the CRA, teachers observed impulsive responses by children. We mitigated this by implementing a brief delay between the appearance of the question and the timeframe in which children could respond. In a subsequent randomized control trial, the CRA was administered 1637 times by Head Start educators. The assessment took an average of 9.8 min to administer. CRA scores were normally distributed and increased on average as a function of age. Girls scored slightly higher than boys, although the difference was not significant when age and race were taken into account. The CRA showed acceptable levels of reliability in terms of internal consistency (α = 0.78) and test–retest reliability (r = 0.65). Results from a 3PL indicate that the CRA has suitable levels of difficulty and skill level discrimination for 3-to-5-year-olds. The 3PL guessing parameter was 0.28, indicating that steps to reduce impulsive responses were successful. We conclude that the CRA has suitable properties for assessing preschool-age children’s CT skills and coding readiness. Full article

The present study examines the potential of the Symptom Checklist-90-Revised (SCL-90-R) as a measure for the Hierarchical Taxonomy of Psychopathology (HiTop) model. Two structural models were evaluated. In Model 1, the SCL-90-R dimensions were allocated to somatoform (comprising somatization), internalizing (comprising obsessive–compulsive, interpersonal sensitivity, depression, anxiety, and phobic anxiety), and antagonistic disinhibited (comprising hostility) spectra. Model 2 included an additional detachment spectrum (comprising paranoid ideation and psychoticism). Method: A total of 1594 adolescents [52.2% boys; age ranged from 14 to 17 years; mean age (SD) = 16.04 years (0.737 years)] from the general community in Athens completed the SCL-90-R and the Funf-Faktoren-Fragebogen fur Kinder (FFFK). Confirmatory factor analysis (CFA) was conducted to validate the proposed models. Results: The findings supported Model 1, demonstrating adequate global fit, salient and significant factor loadings, discriminant validity, reliability, and external validity of the factors. Conclusions: These results indicate that the SCL-90-R scales of somatization, obsessive–compulsive, interpersonal sensitivity, depression, anxiety, hostility, and phobic anxiety are appropriate measures for the corresponding HiTop dimensions. However, the scales for paranoid ideation and psychoticism were not suitable for this purpose. The theoretical contributions and conclusions are discussed, highlighting the implications of these findings for the clinical and theoretical application of the SCL-90-R in psychopathological assessment and research.

Background: Children often present to primary and specialty care clinics with multiple somatic symptoms of nonspecific origin that can be highly distressing and prompt significant health service use. We evaluated the psychometric properties of the eight-item Children’s Somatic Symptoms Inventory (CSSI-8) as a brief measure of somatic distress that could be easily integrated into clinical systems. Method: Eight items from the 24-item CSSI were selected based on their representation of multiple bodily systems, association with high base rates, and ability to maximize the separation of the items’ Rasch measure scores. The psychometric quality of the eight-item scale was evaluated in 876 pediatric patients with chronic abdominal pain and a nonclinical sample of 954 school children using methods from three psychometric models (the classical test theory, Rasch modeling, and confirmatory factor analysis). Results: The CSSI-8 showed good measurement properties on an extensive array of psychometric criteria, had adequate Rasch person separation reliability for a brief instrument (r_sep = 0.74–0.75), and distinguished between clinical and nonclinical youth. Girls in both groups had significantly higher CSSI-8 scores than boys. Norms for the clinical sample are presented. Conclusions: The CSSI-8 is a psychometrically sound measure suitable for use as a brief dimensional assessment of pediatric somatic distress. Full article

The aim of this study was to investigate the reliability of the tennis-specific change of direction (77COD) test with vertical jump tests (Squat Jump and Countermovement Jump) in adolescent tennis players. A total of 58 athletes (31 girls, 27 boys) actively playing tennis, with an average age of 10.57 ± 2.54 years, participated in the study. Tests and retests were completed within 2 weeks. Bland–Altman (B&A) plots were established and Pearson’s correlation analysis was conducted on the 77COD, CMJ, and SJ tests. Simple linear regression analysis (enter method) was used to determine the significant predictors of the 77COD variable from the SJ-CMJ variables. The SJ and CMJ were found to be highly negatively correlated with the 77COD test (−0.72 ≤ r ≤ −0.74). The test–retest reliability of the 77COD test was found to be very high, with an intraclass correlation coefficient (ICC) of 0.95. Our findings showed that the 77COD test is suitable for determining COD ability in adolescent tennis players. In addition, vertical jump heights are an informative and practical performance indicator for 77COD. In conclusion, the 77COD test is a COD test that can be used in coaching practices without the need for complex testing materials. Full article

Dyslexia, often referred to as a specific reading disability, affects many students around the world. It is a neurological disorder that affects the ability to recognise words, and it causes difficulties in writing and reading comprehension. Previous computer-based methods for the automatic detection of dyslexia in children have had low efficiency due to the complexity of the test administration process and the low measurement reliability of the attention measures used. This paper proposes the use of a student’s mobile device to record the spatio-temporal trajectory of attention, which is then analysed by deep neural network long short-term memory (LSTM). The study involved 145 participants (66 girls and 79 boys), all of whom were children aged 9 years. The input signal for the neural network consisted of recorded observation sessions, which were packets containing the child’s spatio-temporal attention trajectories generated during task performance. The training set was developed using stimuli from Benton tests and an expert opinion from a specialist in early childhood psychology. The coefficients of determination of $R2\sim 0.992$ were obtained for the proposed model, giving an accuracy of 97.7% for the test set. The ease of implementation of this approach in school settings and its non-stressful nature make it suitable for use with children of different ages and developmental stages, including those who have not yet learned to read. This enables early intervention, which is essential for effective educational and emotional support for children with dyslexia. Full article

Dental general anesthesia (GA) is a day-stay procedure and is a suitable choice for complicated cases. It is undertaken in a controlled hospital setting that ensures the quality, safety, efficacy, and efficiency of dental treatment. The purpose of this study is to determine the prevalence, severity, duration, and factors related to the occurrence of postoperative discomfort in young children following GA in a general hospital. This study includes a minimum sample size of 23 children that were undergoing GA over a 1-month period. Informed consent was obtained from the parent prior to the treatment. A preoperative questionnaire via the Survey Monkey program was used for the purposes of recording the responses of the survey population. All data related to the immediate postoperative period while the child was in the post-anesthetic recovery room (PAR) was collected and assessed by one of the investigators using the Face, Legs, Activity, Cry, and Consolability (FLACC) pain assessment scale. Postoperative data was gathered using the Dental Discomfort Questionnaire (DDQ-8) and was performed by phone 3 days after the GA procedure. The participating 23 children ranged from 4 to 9 years old (mean 5.43 ± 1.53). A total of 65.2% were girls and 34.8% were boys, with 30.4% experiencing a recent history of pain. Full article

Several factors affect students’ mathematics grades and standardized test results. These include the gender of the students, their socio-economic status, the type of school they attend, and their geographic region. In this work, we analyze which of these factors affect assessments of students based on fuzzy logic, using a sample of 29,371 Italian high school students from the 2018/19 academic year. To combine grades assigned by teachers and the students’ results in the INVALSI standardized tests, a hybrid grade was created using fuzzy logic, since it is the most suitable method for analyzing qualitative data, such as teacher-given grades. These grades are analyzed with a hierarchical linear regression. The results show that (1) boys have higher hybrid grades than girls; (2) students with higher socio-economic status achieve higher grades; (3) students from scientific lyceums have the highest grades, whereas students from vocational schools have the lowest; and (4) students from Northern Italy have higher grades than students from Southern Italy. The findings suggest that legislators should investigate appropriate ways to reach equity in assessment and sustainable learning. Without proper interventions, disparities between students might lead to unfairness in students’ future career and study opportunities. Full article

Human prepubertal testicular tissues are rare, but organ culture conditions to develop a system for human in vitro-spermatogenesis are an essential option for fertility preservation in prepubertal boys subjected to gonadotoxic therapy. To avoid animal testing in line with the 3Rs principle, organ culture conditions initially tested on human adult testis tissue were applied to prepubertal samples (n = 3; patient ages 7, 9, and 12 years). Tissues were investigated by immunostaining and transmission electron microscopy (TEM), and the collected culture medium was profiled for steroid hormones by liquid chromatography-tandem mass spectrometry (LC-MS/MS). Culture conditions proved suitable for prepubertal organ culture since SSCs and germ cell proliferation could be maintained until the end of the 3-week-culture. Leydig cells (LCs) were shown to be competent for steroid hormone production. Three additional testis tissues from boys of the same age were examined for the number of germ cells and undifferentiated spermatogonia (SPG). Using TEM micrographs, eight tissues from patients aged 1.5 to 13 years were examined, with respect to the sizes of mitochondria (MT) in undifferentiated SPG and compared with those from two adult testicular tissues. Mitochondrial sizes were shown to be comparable between adults and prepubertal boys from approximately 7 years of age, which suggests the transition of SSCs from normoxic to hypoxic metabolism at about or before this time period.

Children aged 3–6 years (preschool children hereafter) are in a critical and sensitive period of developing fundamental movement skills (FMS). While appropriate measurement tools can accurately evaluate their FMS development, such a scale is lacking in China. In this study, a suitable scale for measuring the FMS of preschool children in China was developed by combining process- and results-oriented evaluation methods. The subjects of this cross-sectional study included 21 experts and 358 preschool children (188 boys and 170 girls). Based on a literature review, items suitable for measuring the FMS of preschool children in China were selected, and the final measurement scale includes 12 items in three dimensions: physical locomotion skills, object control skills, and physical stability skills. After a battery of tests to assess its suitability, including inter-rater reliability, test/retest reliability, homogeneity, and construct validity, we find that the proposed measurement scale has good reliability, validity, and sensitivity. This scale reflects the development level of the FMS of preschool children in China and can be used to monitor the FMS of this population in the future. Full article

The aim of this study was to examine the effects of school-based high-intensity interval training (HIIT) on cardiorespiratory fitness and visceral adipose tissue (VAT) in children with obesity. A total of 40 students (11.0 ± 0.6 years; 20 boys) were randomized into an intervention group (IG) and control group (CG). The IG group performed a 12-week HIIT intervention with three sessions per week. Each session included 18 min of training (three sets of eight bouts of 15 s run at 100% maximal aerobic speed (MAS) separated by eight bouts of 15 s recovery run at 50% MAS) in PE class; the CG group were instructed to continue their normal behaviors. All subjects had indices of body mass index (BMI), fat mass (FM), body fat percentage (%BF), fat free mass (FFM), VAT, and maximal oxygen uptake (VO_2max) measured at baseline and post-intervention. The cooperation of students was high, and all 40 students were included in the final analysis. A significant group–time interaction was determined in body composition (p < 0.05), with a significant decrease in BM (−3.4 ± 1.4 kg, p = 0.001; η² = 0.63), BMI (−1.7 ± 0.5, p = 0.001; η² = 0.58), %BF (−3.3 ± 1.4, p = 0.001; η² = 0.54), and FM (−3.2 ± 1.4 kg, p = 0.001; η² = 0.69), and VAT (−22.4 ± 9.8 cm²; p = 0.001; η² = 0.61) in the IG. Furthermore, VO_2max exhibited a significant increase in the IG (4.5 ± 1.6 mL/kg/min, p = 0.001; η² = 0.84) and CG groups (1.7 ± 1.1 mL/kg/min, p = 0.001; η² = 0.44). Integrating regular school-based HIIT sessions is a suitable method to improve body composition, cardiorespiratory fitness, and physical activity in students with obesity.

Validated physical activity (PA) questionnaires are crucial for collecting information in large epidemiological studies during childhood. Thus, this study analyzed the validity of a parent-reported PA questionnaire based on the Children’s Leisure Activities Study Survey by accelerometry in European children aged from 6 to 12 years old. We used data from 230 children of the Human Early-Life Exposome and Infancia y Medio Ambiente projects. Mean differences between moderate-to-vigorous PA (MVPA) reported by the questionnaire and the accelerometer were calculated (min/day), and its associated factors were explored by multiple robust linear regression. The agreement between methods was examined using a Bland–Altman plot. The concurrent validity of assessing MVPA was analyzed by cohort-adjusted Spearman’s partial correlations. ROC curve analysis was also used to explore the questionnaire’s capability to identify active children based on the World Health Organization guidelines. A moderate correlation was found between parent-reported and accelerometer MVPA (rho = 0.41, p < 0.001). The child’s sex (girl) was statistically associated with the mean MVPA difference between methods. However, this questionnaire accurately identified physically active children (area under the curve = 83.8% and 82.7% for boys and girls, cut-points = 68.6 and 45.4 min/day in MVPA, respectively). Consequently, this questionnaire is suitable for classifying active children in order to monitor public health interventions regarding PA. Full article

(1) Background: A Monteggia fracture is an infrequent injury in children. It can be missed during an initial consultation in 20–50% of patients. Chronic radial head dislocation may lead to several complications. Thus, surgical reconstruction of chronic Monteggia injuries is justified. The aim of this study is to analyze the single tertiary center experience in the treatment of neglected Monteggia fractures. (2) Methods: A retrospective study of patients treated for missed Monteggia fractures was conducted. Hospital records, operative charts, follow-up records and a set of X-rays were analyzed for each patient. Radiographic results were graded as good, moderate or poor. The functional status of elbows was estimated using the Mayo Elbow Performance Index. (3) Results: A total of 13 patients (8 boys and 5 girls) aged 4–12 years (mean 7.15) were treated during the study period. An angulation osteotomy of the ulna was performed in ten patients and a radial shortening osteotomy in three patients. A Bell–Tawse annular ligament reconstruction was performed in five patients, and a direct repair was performed in two patients. Eight patients had radiocapitellar trans-fixation. There were nine good radiographic results, three moderate and one poor. The functional result was excellent in nine patients, good in three and poor in one. (4) Conclusions: Our work has many limitations (only 13 patients and different types of operations), and conclusions should be drawn very carefully from such a small and diverse group. The surgical reconstruction of neglected Monteggia fractures in children should be attempted in all patients. Angulation and elongation osteotomies of the ulna are suitable for most patients. If there is a marked overgrowth of the radius, gradual ulnar lengthening and radial head reduction using the Ilizarov method may be a better option. Annular ligament reconstruction is not mandatory.

We conducted this retrospective study to identify potential clinical, polysomnographic, and cephalometric predictors for the treatment outcomes of a tongue-beaded oral appliance (OA) in children with obstructive sleep apnea syndrome (OSAS). In total, 63 patients—50 boys and 13 girls ranging in age from 4 to 16 years—underwent OA treatment nightly for at least 6 months. A baseline digital lateral cephalometric radiograph was obtained for each patient. Multivariate logistic regression analysis was performed to examine predictors for the treatment outcome based on the clinical and cephalometric measurements. Overall, 28 patients responded to the treatment (post-treatment improvement > 50% or apnea–hypopnea index (AHI) < 1/h), and 35 did not (post-treatment improvement < 50% and AHI ≥ 1/h). Significantly larger cranial base angle (SNBa), smaller lower gonial angle (LGo Angle), and shorter length of anterior cranial base (SN) were found in responders. Smaller lower gonial angle (LGo Angle) and smaller anterior cranial base (SN) predict a favorable outcome for pediatric OSAS using a tongue-beaded OA. This finding will equip practitioners with additional insights when selecting suitable candidates for OA therapy in pediatric patients. Full article

The present study aimed to analyse and contrast the experiences of six Preservice Physical Education Teachers (onwards PPET) from two different socio-demographic contexts, Spain and Ireland, regarding the use of Teaching Personal and Social Responsibility (henceforth TPSR) during their work placement. The sample consisted of six students aged between 21 and 25 years (three boys and three girls), in their final year of their bachelor’s degree, who had completed their work placement within the education pathway in different schools in Ireland and Spain. Each student participated in a semistructured interview to find out about their practicum experience, the relevance of TPSR and its relation to occupational socialisation theory. After transcription of the interviews, the results show great similarity between the two contexts, with a positive assessment of the experience and its high relevance for both the teacher tutor and the teachers during their nonuniversity education. Spanish students largely described the importance of past school experiences, showing a very positive assessment of past experiences as PE teachers. On the other hand, it is the students from Ireland who placed greater value on the applicability of TPSR in other subjects. In addition to having more experience using other pedagogical models, they also emphasised the importance of planning before applying methodologies such as TPSR.TPSR is highlighted as a suitable model for the promotion of social values in the classroom, although the training received during the degree course is insufficient for the proper application of the model. It is concluded that TPSR was perceived by Spanish and Irish students as a suitable methodology for teaching undergraduate students, but the students’ previous experiences must be taken into account.
