The average age of patients was 13.4 ± 3.5 years. All children were examined immediately after detection of HBV infection. Chronic hepatitis B was confirmed by the determination of HBsAg 6 months after its first detection. In addition, the following markers were studied: anti-HBcor IgM, anti-HBcor total, HBeAg, anti-HBe. To exclude hepatitis D, total anti-HDV was determined. HBV DNA was determined by PCR (sensitivity of the method was 10–15 IU/mL). The criterion for inclusion of patients with chronic hepatitis B in the study was the consent of parents and/or patients. The exclusion criterion was the presence of anti-HDV. Results. There were significantly more boys with chronic hepatitis B than girls – 68.3% versus 31.7%, respectively; p < 0.001. Children aged 15–17 years were observed more often, both among boys (46.5%) and girls (47.5%). Vertical transmission was observed in 27.7%, surgical interventions – in 19.0%, transfusion-transmission – in 22.2%, in 31.1% – the source was not identified. The Asthenic syndrome was significantly more common – in 67.5%, pain syndrome – in 53.2%, less common dyspeptic syndrome – in 32.5%. Hepatomegaly was observed in 45.2% of children. Concomitant diseases were recorded in 77.0%. Cytolytic syndrome was registered more often than other syndromes – 69% versus 51.6% (cholestatic) and 22.6% (mesenchymal inflammatory). HBV HBeAg(+) was registered in 69.8% of children and HBV HBeAg(-) in 30.2%; p < 0.001. Patients with moderate viral load (VL) predominated (51.6%). HBV HBeAg(+) was characterized by moderate to high VL in 93.2% of cases versus 6.8% with minimal VL; p < 0.001, and HBV HBeAg(-) was characterized by minimal VL in 55.3% and the absence of children with high VL; p < 0.001.

Published: March 2024

The utilization of computers in various engineering and mathematical fields has become increasingly important in recent times. In computational and applied mathematics, computer programs can be used to efficiently process complex data in mere seconds. By utilizing different computer tools and programming languages, computers can manipulate various iterative algorithms to solve nonlinear problems. The convergence rate and computational costs per-iteration are essential factors that determine the effectiveness of an iterative algorithm. This article introduces a new and highly efficient iterative approach of sixteenth order. The authors propose a four-step iterative optimal derivative-free method for solving non-linear equations that arise in engineering application problems. The proposed method achieves an accuracy of order sixteen with only five functional evaluations, and the efficiency index is 1.741. To demonstrate the performance of the method, the authors present several numerical examples, application problems, and a study of dynamics, comparing the method with other available methods of the same order in the literature. Numerical results and dynamics are obtained using computer tools.

This research aims to investigate the strategies that EFL high school students use to overcome their speaking anxiety in the classroom context in the academic year 2022/2023. This study employed a qualitative method. The data were collected through interviews with three participants from a private secondary school in Yogyakarta and semi-structured interviews were conducted to gain strategies used by participants to cope with foreign language speaking anxiety. The data was analyzed using thematic analysis. The overall results show that the three participants experienced anxiety when carrying out learning activities in class, both when communicating, receiving evaluations, and when taking grades. In this study, it was also found that participants had strategies to overcome their EFL speaking anxiety (i.e., preparation, relaxation, peer seeking, and resignation), which could help them deal with EFL speaking anxiety in the classroom context. Therefore, with this strategy, students can have lower anxiety when carrying out learning activities in class. This research offers some ways to reduce anxiety and enhance classroom experiences. It emphasizes the need for further research on anxiety's broader impact and suggests the role of teachers in supporting students with speaking anxiety.

A mismatch of species thermal preferences to their environment may forewarn that some assemblages will undergo greater reorganization, extirpation, and possibly extinction, than others under climate change. Here, we examined the effects of regional warming on marine benthic species occupancy and assemblage composition over one-million-year time steps during the Early Jurassic. Thermal bias, the difference between modelled regional temperatures and species’ long-term thermal optima, predicted species responses to warming in an escalatory order. Species that became extirpated or extinct tended to have cooler temperature preferences than immigrating species, while regionally persisting species fell midway. Larger regional changes in summer seawater temperatures (maximum + 10°C) strengthened the relationship between species thermal bias and the escalatory order of responses, which was also stronger for brachiopods than bivalves, but the relationship was overridden by severe seawater deoxygenation. At + 3°C seawater warming, our models estimate that around 5% of an assemblage’s pre-existing benthic species was extirpated, and around one-fourth of the new assemblage being immigrated species. Our results validate thermal bias as an indicator of future extinction, persistence, and immigration of marine species under modern magnitudes of climate change.

Unmanned Aerial Vehicle (UAV) route planning is an intricate issue that requires the comprehensive consideration of multiple factors and the combination of suitable strategies to achieve efficient and safe flight paths. Its purpose is to plan a suitable navigational path for the drone to achieve a specific task or avoid obstacles. In practical applications, UAVs are usually required to accomplish tasks in a variety of complex environments, resulting in the feasible flight paths will be reduced and path planning for UAVs becomes difficult. Accordingly, we design a simple yet useful planner, called Self-adaptive Golden Equilibrium Optimization algorithm (SGEO). The proposed algorithm combines the new self-adaptive approach, the acceleration control factor and the Golden-SA strategy in order to balance the exploitation and exploration capabilities. The novel self-adaptive strategy is used to expand the global search range of the algorithm and enhance its ability for global exploration; the acceleration control factor is introduced to control the parameters a1 and a2 and improve the convergence ability of the algorithm; the Golden-SA strategy helps the candidate particles achieve better balance between different dimensions based on the golden ratio and sine function, this enables the particles to explore the search space more comprehensively. The limitations in UAV route planning are translated into the objective function, and four more algorithms are introduced to compare with SGEO in two different circumstances. The simulation findings reveal that SGEO excels at three-dimensional path planning for UAV in complicated environments.

Objective
To understand the prevalence and the drug resistance of the Staphylococcus aureus (S. aureus) isolates harboring Panton–Valentine leukocidin (PVL) gene in the Shandong Provincial Hospital in 2023. The clinical application values of white blood cell (WBC), C-reactive protein (CRP), and neutrophil-to-lymphocyte ratio (NLR) in the diagnosis of PVL-positive S. aureus infection were investigated.
Methods
166 S. aureus isolates were separated from inpatients in the Shandong Provincial Hospital in 2023. We determined the presence of the mecA gene and genes encoding PVL using PCR, and the department distributions and drug resistance of the isolates were analyzed. Groups were grouped according to the mecA and PVL gene test results. Contemporaneous 100 subjects undergoing healthy physical examination were selected as the control group. The levels of WBC, CRP, and NLR of each group were collected, and the clinical application values of WBC, CRP, and NLR for PVL-positive S. aureus infection were compared.
Results
Among the 166 strains of S. aureus, 73 isolates were Methicillin-resistant S. aureus (MRSA). The prevalence of MRSA among inpatients in the Surgical Department, Internal Medicine Department, Intensive Care Unit (ICU), Emergency and Pediatric Department was 64.4%, 12.3%, 15.1%, 4.1% and 4.1%, respectively. PVL genes were detected in 88 strains of S. aureus, most of which were Methicillin-susceptible S. aureus (MSSA). The levels of WBC, CRP, and NLR increased significantly during S. aureus infection, and the level of NLR in the PVL-positive group was significantly higher than that in the PVL-negative group (Z= -2.13, P = 0.033). Still, the levels of WBC, and CRP were rarely different between the PVL-positive group and PVL-negative group.
Conclusions
This study analyzed the prevalence of S. aureus harboring the PVL gene in Shandong Provincial Hospital in 2023. Compared with WBC and CRP, NLR had a higher clinical application value for PVL-positive S. aureus, and NLR can be used as a screening indicator for PVL-positive S. aureus infection.

Trachemys scripta (Pond Sliders), a North American freshwater turtle species, includes three subspecies, T. s. scripta, T. s. elegans, and T. s. troostii, whose relationships and status remain enigmatic. Particularly intriguing is T. s. troostii, which exhibits weak genetic distinctiveness from the other two subspecies. Rather than viewing their evolution as a simple bifurcating process, our study delves into the complex demographic history of T. s. troostii. We leveraged mitochondrial control region DNA sequences to investigate the subspecies’ demographic history and intraspecific systematics, with special emphasis on T. s. troostii. Haplotype network and phylogenetic analyses using Maximum Likelihood and Bayesian Inference consistently revealed that T. s. troostii is incompletely differentiated genetically from T. s. elegans. To investigate the demographic history of the three subspecies, we conducted the model-testing-based approximate Bayesian computation (ABC) analysis. Our findings support the hypothesis that T. s. troostii originated through admixture between T. s. scripta and T. s. elegans, with later secondary contact with the latter shaping the genetic makeup of present-day T. s. troostii populations.

Purpose
Lutein (LUT) is a carotenoid found in fruits, and green vegetables with potent antioxidant, anti-inflammatory and cardioprotective action. However, the mechanisms involved in the cardioprotection against cardiac hypertrophy (CH) remains unkown.
Objectives
Investigate the anti-hypertrophic action of LUT in rats using the isoproterenol-induced CH model.
Methods
For CH induction, isoproterenol (ISO; 4.5 mg/kg/day, 7 days, i.p) was administrated and animals were treated with LUT (20 mg/kg/day, 7 days) or apocynin (APO, 10 mg/kg/day, 7 days). To investigate the participation of the nitric oxide (NO) pathway in the mechanism of action of LUT, the animals were treated with L-NAME (20 mg/kg/day, 7 days), an inhibitor of NO synthase.
Results
LUT and APO animals showed attenuated morphometric, fibrosis and inflammatory enhancement compared to ISO group, in addition to reducing the infarct area and the mortality rate triggered by ISO. Serum levels of CPK-TOTAL, CPK-MB, LDH, AST and ALT were significantly reduced in animals treated with LUT when compared to the ISO group. LUT attenuated the electrocardiographic changes induced by ISO (increase of QRS and QTc and inversion of T wave) and prevented the reduction of left ventricular pressure and heart rate in the ISO group. ISO increased the production of reactive oxygen species (ROS) in the heart which was prevented by LUT. ISO increased the Bax protein expression, which was attenuated by LUT treatment. Also, L-NAME partially reversed the LUT-mediated cardioprotection.
Conclusion
The results show that LUT exerts a cardioprotective effect against CH in rats partially related to NO pathway.
