Authors: Jakubík Ján , Broďáni Jaroslav 
Published: January 2025

Objectives. The objective of this study was to verify the impact of the IAAF project “Kids’ Athletics” on the physical performance of pupils in primary education through the design and implementation of an athletics program.
Materials and methods. The present study was conducted using a two-group non-concurrent experiment, in which the experimental group (decimal age 8.64 years) consisted of 50 probands and the control group (decimal age 8.55 years) consisted of 60 probands aged 8-9 years. Additionally, 8 physical abilities tests were used to obtain selected indicators of the level of motor performance and probands’ skill. The effectiveness of the 7-month experimental program was evaluated using comparative analysis through non-parametric statistical methods: Wilcoxon and Mann-Whitney U test and substantive significance assessment: Cohen (r). The difference in the progress of both samples was also determined.
Results. From a total of 8 motor tests in the experimental sample, a progress was observed in all 8 cases, of which the following changes were significant in 6 tests: Movement Set with Bar (z = 3.84, p < 0.00, r = 0 .54), Static Pull‑Up Hold (z = 3.53, p = 0.00, r < 0.50), Sit-Up (z = 5.29, p < 0.00, r = 0.75), 3-Way Ball Rolling (z = 4.31, p < 0.01, r = 0.61), the 4×10m Shuttle Run (z = 4.20 m, p < 0.01, r = 0.59) and the Beep Test (z = 4.64, p < 0.01, r = 0.66). In the case of the control group, there was a progress at the level of statistical significance in the Sit-Up (z = 2.87, p < 0.01, r = 0.37), in the 4×10 m Shuttle Run (z = 4.94, p <0.01, r = 0.64) and the Beep Test (z = 2.98, p<0.01, r = 0.38).
Conclusions. It has been proven that the “Kids’ Athletics” program, composed of selected disciplines of Kids’ Athletics supplemented by athletic movement games, has a significant impact on a wider range of physical abilities in 8- to 9-year-old children compared to the traditional content of the ISCED 1 state education program. Based on the findings of this study, as well as the comparison of other research works devoted to related issues, it is pointed out the feasibility of implementing such an athletic program into the annual timetables of Physical Education and Sports in primary education at this particular age period.
Applying the ETAS Model to Simulate Earthquake Sequences for Hazard Assessment in Crustal Seismicity Regions with Scarce Data

ABSTRACT
Considering earthquake sequences in seismic hazard and risk analyses has become increasingly important. Many sequences around the world demonstrated that limiting the consideration to only mainshocks leads to underestimation of hazard and, more importantly, risk. Among the methods to simulate earthquake sequences, the epidemic-type aftershock sequence (ETAS) model has shown notable accuracy in representing these complex sequences making it a valuable tool for seismic hazard and risk assessment. However, the ETAS model is rather complex and for regional applications it requires many parameters to be calibrated. The calibration is most effective when a long instrumental catalog complete to low-magnitude events is available. However, this is rarely the case. Our study investigates the possibility of using the ETAS model with parameter values calibrated for a region with many recent sequences (namely central Italy) to simulate realistic sequences in two other crustal seismicity regions, namely Türkiye and Croatia. We compare three options (1) using a set of ETAS parameters calibrated based on local data, (2) fixing most ETAS parameters to values derived from a well-studied region with many recent sequences (central Italy) while locally calibrating the total background rate and productivity term (SimplETAS [SE] parameter set, akin to the simplETAS methodology of Mancini and Marzocchi (2023), and (3) fixing all ETAS parameters to values from central Italy except for the total background rate (Set of Central Italy [SCI] parameter set). The results show that simplified approaches based on central Italy data (SE and SCI) can produce simulated earthquake sequences that align well with the observed data even for Croatia and Türkiye. This reflects the applicability of modeling earthquake sequences for hazard and risk applications in many crustal regions where good quality observed instrumental catalogs complete to low-magnitude events are not available or they are available but do not contain significant sequences.

Background: A ‘gold standard’ for the treatment of cervical insufficiency is by inserting cervical cerclage. This intervention may not be successful in all cases. Hence, there is a need to assess the methods and pregnancy outcomes of cervical cerclage, and draw conclusion from the findings. Objectives were to assess the methods and pregnancy outcome of cervical cerclage in women with cervical incompetence at the federal teaching hospital, Ido-Ekiti, Ekiti State.
Methods: This is a 5-year retrospective review of the records of women that had cervical cerclage between June 2019 and June 2024. The data were retrieved and analyzed for their socio-demographic factors, clinical characteristics, landmark past clinical events, number of past cerclage insertions, and the methods and pregnancy outcomes of index cerclage. The data obtained were analyzed using SPSS version 26.
Results: There were 27 cases of cerclage placement per 2,489 deliveries (1 in 92 births) during the period under review. The mean age was 33.6±4.8 years. Majority (74.1%) aged 31 to 40 years. Two-thirds of women (66.7%) had no prior births, 25.9% had one birth, and 7.4% had two or more births. The McDonald’s technique was the most commonly used method, accounting for 92.6% of cases. Favourable outcome was recorded in 85.2% of the women.
Conclusions: This study showed that majority of the women treated with cerclage had successful pregnancy outcome, further supporting this intervention as a “gold standard” for managing cervical incompetence.

Background: Pregnancy is a unique physiological state characterized by profound changes in a woman's body to support fetal growth and development. Adequate nutrition is vital during pregnancy to meet the increased demands of both the mother and the developing fetus. Among the various nutrients required during pregnancy, vitamin B12 stands out as a critical micronutrient. It plays a pivotal role in cellular replication, neurodevelopment, and the synthesis of DNA, making it essential for the proper growth and development of the fetus. This study was conducted to evaluate vitamin B12 deficiency in pregnancy and its association with maternal and fetal outcomes.
Methods: This was a cross-sectional study conducted among consecutively selected pregnant women who had just given birth to a single live baby admitted to the department of obstetrics and gynecology and also the department of feto-maternal medicine, Bangabandhu Sheikh Mujib medical university (BSMMU), Shahbagh, Dhaka from September 2022 to August 2023. A total of 90 women of 18-40 years of age at their 28-40 weeks of gestation were included in this study. Study subjects with vitamin B12 levels of <200 pg/ml were considered as the low level (group I), whereas level ≥200 pg/ml was considered as the normal (group II). Observations were undertaken on pregnancy complications and perinatal outcomes, which were compared between the two groups.
Results: The study revealed majority (57.8%) of the study participants age were within 26-34 years, a housewife was 74.4% and multigravida constituted 70.0% of the respondents. The 31 (34.4%) of the respondents had vitamin B12 level below 200 pg/mL and 59 (65.60%) women had normal serum vitamin B12 levels (≥200 pg/mL). Congenital hydrocephalus was observed in 16.1% of the group I mothers compared to only 1.7% in group II (p=0.017) and neural tube defect was present in 9.7% of group I but in none of group II mothers (p=0.038).
Conclusions: Mothers having vitamin B12 deficiency experience significantly higher rates of oligohydramnios, fetal hydrocephalus, and neural tube defects compared to those with normal vitamin B12 levels. However, there was no significant maternal complication.

Abstract

Intense tropical cyclones (TCs), which pose significant threats to human life and property, often occur within a short period of time each year, known as the intense TC season. Changes in the lengths of intense TC seasons under climate change are critical scientific and socioeconomic issues. While recent research has investigated trends in overall TC seasons, the response of intense TC seasons to climate change remains underexplored. Here, we discover that intense TC seasons have been lengthening globally since 1980, with significant increasing trends ranging from 8.5–14.2 days/decade across all basins, equivalent to 6.5-21.2% increase in intense TC season lengths per decade. This is primarily driven by the enhancing thermodynamic disequilibrium between ocean and atmosphere due to recent oceanic warming, which raises the maximum potential intensity of TCs outside the traditional intense TC seasons. Meanwhile, changes in atmospheric circulation play a minor role. As a result, off-season TCs are more likely to develop into intense TCs. The findings in this study indicate an increasing exposure of human societies to intense TC risks outside historical seasonal norms. This suggests the urgent need for preparation and mitigation measures for the potential risks of intense TCs under future climate change.

Published: January 2025

Abstract

Purpose
Glioblastoma is the most common primary brain malignancy. Though literature has suggested the association of glioblastoma outcomes and socioeconomic status, there is limited evidence regarding the association of neighborhood-level socioeconomic deprivation on glioblastoma outcomes. The aim of this study was to assess the impact of neighborhood-level socioeconomic deprivation on glioblastoma survival.
Methods
We retrospectively reviewed all adult glioblastoma patients seen at a single institution from 2008 to 2023. Neighborhood deprivation was assessed via Area Deprivation Index (ADI), with higher ADI indicating greater neighborhood socioeconomic deprivation. Log-rank tests and multivariate cox regression was used to assess the effect of ADI and other socioeconomic variables while controlling for a priori selected clinical variables with known relevance to survival.
Results
In total, 1464 patients met inclusion criteria. The average age at diagnosis was 60 ± 14 years with a median overall survival of 13.8 months (IQR 13-14.8). The median ADI of the cohort was 66(IQR 46-84). Patients with high ADI had worse overall survival compared to patients with low ADI (11.7 vs 14.8 months, p=.001). In the multivariable model, patients with high ADI had worse overall survival (HR 1.25, 95%CI 1.09-1.43). To account for changes in WHO guidelines, we implemented the model on patients diagnosed between 2017-2023 and findings were consistent (HR 1.26,95%CI 1.01-1.56).
Conclusion
We report the first study demonstrating glioblastoma patients with higher neighborhood deprivation have worse survival after controlling for other socioeconomic and biomolecular markers. Neighborhood socioeconomic status may be a prognostic marker for glioblastoma survival.

Abstract

Teacher performance, motivation, and self-identity are critical for the success of Chinese vocational colleges. These factors shape educational quality and institutional effectiveness. Despite their importance, few studies have explored the interplay in this educational context. This study employed a descriptive-correlational research design to examine the relationships between teacher self-identity, job satisfaction, and performance. Data from 100 teachers were analyzed using validated survey instruments. Descriptive statistics summarized the trends, while regression and correlation tests determined the strength of the relationships. The findings revealed high levels of self-identity (M = 3.376, SD = 0.44), job satisfaction (M = 3.41, SD = 0.43) and teaching performance (M = 3.52, SD = 0.42). Teachers have excelled in adapting teaching methods and fostering student engagement. Interpersonal relationships, including collaboration and trust, further enhance satisfaction and performance. This study highlights the interconnectedness between teacher identity, motivation, and effectiveness. These results emphasize the need for professional development, equitable resource allocation, and collaborative environments to sustain high performance. By addressing these areas, institutions can enhance teacher satisfaction, improve student outcomes, and support vocational education reform. Future research should expand on these findings across diverse contexts.

Abstract

Background: Patients with breast cancer experience distress, treatment-related discomfort, and fear of recurrence, from initial diagnosis through survivorship.
Aims: This study aimed to assess the effects of breathwork interventions on the mental health and quality of life of breast cancer patients and survivors.
Methods: We searched multiple databases for randomized controlled trials involving breathwork interventions in patients with breast cancer.
Results: Of the 5,909 items screened, 16 studies involving 1,726 participants met the inclusion criteria. Breathing interventions included yoga (n=9), qigong (n=4), and other breathing techniques (n=3). We found that the highest average risk of bias was in the randomization process, with challenges in accurately evaluating deviations from intended interventions due to unquantified adherence to at-home practices, although overall bias in the included studies was generally low. Interventions were prescribed daily or weekly, lasting from one week to two years. Outcomes included treatment side effects, fatigue, sleep, quality of life, biomarkers (e.g., inflammatory markers), psychosocial factors, anxiety, and depression.
Conclusions: Although positive outcomes were reported in domains of quality of life and emotional wellbeing, null findings were reported for vasomotor symptoms such as hot flashes for breathing interventions. The wide range of interventions and outcomes administered to patients in various phases of the breast cancer care continuum complicates firm conclusions. Recruitment and adherence issues were noted in multiple studies. Future research should standardize outcome measures, increase accessibility of the intervention (ie via Telehealth) to improve adherence, and include longer follow-up periods to evaluate survival and recurrence.
Evaluation and prediction of groundwater quality for irrigation using regression and machine learning models
Authors: Shaw Souvick Kumar , Sharma Anurag 
Published: January 2025

ABSTRACT

This study evaluates and predicts six water quality indices such as sodium adsorption ratio (SAR), Kelly's ratio (KR), percentage sodium (%Na), permeability index (PI), exchangeable sodium percentage (ESP), and irrigation water quality index (IWQI) using multivariate regression models (MLR, PLSR, PCR, and WLSR) and machine learning (ML) algorithms (ANN, SVM, CART, CRRF, and KNN). The study analyzes data from 360 dug wells in Sundargarh district, India, during 2014–2021 with 70% used for training and 30% for testing. Spatial mapping of SAR, KR, ESP, and PI exhibits higher suitability of groundwater. The Mann–Kendall test of trend analysis shows a monotonic increasing and decreasing trend for SAR, KR, %Na, ESP, PI, and IWQI, respectively, at p &gt; 0.05 during 2014–2021. Principal component analysis and discriminant analysis identify Na+, SAR, KR, %Na, and PI as the most influential WQ variables affecting the groundwater quality for this study area. MLR and WLSR models are superior in predicting SAR and ESP, while ANN is the best-suited ML model for SAR, KR, %Na, PI, and ESP. CRRF predicts IWQI with a relatively higher accuracy. These findings demonstrate the effectiveness of ML models in improving irrigation water quality assessment, providing valuable insights for groundwater-based crop management.

Published: January 2025

Background
Denosumab, a monoclonal antibody directed against RANK-Ligand, inhibits the formation, function, and survival of osteoclasts, leading to the inhibition of bone resorption, resulting in increased bone mass and prevention of fractures. Despite the availability of biosimilar denosumab in India for more than 5 years, Real-world Evidence (RWE) on the control of disease severity, tolerability, and safety of these biosimilars is lacking.

Objectives
This analysis is intended to compare the in-clinic effectiveness and safety of the Indian drug authority-approved denosumab biosimilar (Intas-Pharma) with the innovator denosumab.

Methods
Data of osteoporotic patients receiving either innovator denosumab or biosimilar denosumab (60mg SC every 6 months) for 2 years in routine clinical practice as per patient choice were evaluated. Effectiveness was measured based on the change in Lumbar spine (LS-TS) and Total Hip T scores (HIP-TS). Student t-test was carried out to evaluate intragroup change in T-scores at both sites and compare inter-group T-scores at baseline, as well as after 2 years of denosumab treatment at both sites. Adverse events reported in both groups were noted.

Results
A total of 49 osteoporotic patients receiving denosumab (n=28 biosimilar denosumab, n=21 innovator denosumab) were evaluated. All patients received concomitant vitamin D and calcium throughout the study duration.
The mean LS-TS values for the innovator and biosimilar groups at baseline were -3.85±0.20 and -3.82±0.21, respectively, while the mean HIP-TS values for the innovator and biosimilar group at baseline were -3.60±0.22 and -3.57±0.21, respectively. Both groups were comparable at baseline, and there was no significant difference between the two groups in terms of T scores at both sites. After 2 years of denosumab treatment, mean LS-TS values for the innovator and biosimilar groups reached -2.82±0.26 and -2.74±0.25, respectively, while the mean HIP-TS values for the innovator and biosimilar group were recorded to be -2.41±0.27 and -2.40±0.24, respectively. When post-treatment T scores were compared, there was no significant difference between the two groups at any of the sites.
When an intra-group change in T scores from baseline over 2 years was evaluated, both innovator and biosimilar denosumab groups were observed to have significant improvement (p<0.0001) in mean LS-TS as well as HIP-TS values. No severe adverse effects were noted in any group, and the safety profile of both groups was comparable.

Conclusion
Biosimilar denosumab was found to be as effective as innovator denosumab in increasing bone mineral density at the lumbar spine as well as total hip among osteoporotic patients attending Indian rheumatology clinics.

Published: January 2025

Current study designed to explore the anti-corrosion effect of 2-hydroxy-5-{(E)-[4-(pyridin-2ylsulfamoyl)phenyl]diazenyl} benzoic acid (sulfasalazine, SSZ) on carbon steel. 1 M of HCl solution used as an aggressive medium. The corrosion process was significantly inhibited by SSZ using simple, direct and accurate method (hydrogen evolution) to measure corrosion inhibition process. The results showed that the corrosion inhibition efficiency increased with increasing the inhibitor SSZ concentration. Three different concentrations of the inhibitor SSZ (0.1 × 10−3, 0.5 × 10−3, and 1.0 × 10−3 M) were used in the corrosion experiment. Results showed a maximum inhibition efficiency (89.74%) achieved at the concentration of 1 × 10−3 M and the temperature of 308 K. The calculations of the hydrogen evolution method showed that the investigated SSZ acted as a mixed-type inhibitor. Adsorption of SSZ on the carbon steel surface obeys the Langmuir adsorption isotherm. The quantitative chemical parameters were calculated using density functional theory (DFT). In addition, full geometry optimizations were performed using DFT with B3LYP. The correlation between the theoretical and experimental results is discussed. The theoretical and experimental studies showed that SSZ is a good inhibitor as the maximum anti-corrosion activity was achieved at the highest concentration of the SSZ (1 × 10−3 M), and the lowest temperature used in the experiment.
