Authors: Zhang Shudi , Xiao Qingtian , Chen Fangfang , Chen Yupei , Wu Hongtan , Wang Gueyhorng 
Published: February 2025

An integrated investigation of pulse energy (0–0.8 mJ), pulse width (2–500 ns),
and repetition rate (1 Hz–4 MHz) was carried out on
laser-induced breakdown spectrometry (LIBS). An increase in pulse
energy led to a significant signal elevation, yet its speed slowed
down at a longer pulse width, which helps to lessen the electron
density and ablation threshold. The repetition rate showed greater
impact at higher pulse energy, and a threshold of about 200 Hz
was observed for signal enhancement, exceeding which the ablation
threshold of aluminum decreases logarithmically in the case of a
250 ns pulse width. Up to 29.0% of the sensitivity enhancement
and 43.9% of the limit of detection (LOD) improvement were obtained
under a high laser repetition rate of 20 kHz, resulting in an
agreeable LOD of down to several tens of ppm considering the low laser
irradiance applied here. In summary, to achieve better
quantification results, higher pulse energy, moderate pulse width, and
higher repetition rate should be applied.

Aim
To investigate whether high-intensity interval training (HIIT) improves physical performance, systolic blood pressure, and markers of oxidative stress and inflammation in skeletal muscle of spontaneously hypertensive rats (SHR).

Methods
Nineteen male SHR rats were randomly assigned to two groups: sedentary (SHRC) and trained (SHR+T). The SHR+T group trained five times a week for eight weeks on a treadmill, while the SHR group remained without any exercise stimulus throughout the experimental period. Maximum physical performance and systolic blood pressure (SBP) were assessed before and after the training period. The following variables were measured in the tibialis anterior (TA) muscle: gene expression of the NADPH oxidase complex (NOX2, NOX4, p22phox, p47phox) and the NF-kB pathway (NF-kB and Ik-B), lipid peroxidation (malonaldehyde; MDA), protein carbonylation, hydrophilic antioxidant capacity (HAC) and pro-inflammatory cytokines (IL-6 and TNF-α).

Results
SHR+T rats showed higher physical performance and levels of IL-6, and lower SBP and protein carbonylation (p<0.05), compared with SHRC rats. No significant differences (p>0.05) were observed in the other variables.

Significance
Our results indicate that HIIT is an effective non-pharmacologic strategy to improve physical performance, reduce SBP, and modulate the skeletal muscle oxidative damage and inflammation in hypertensive rats.
How value perspectives influence decision-making in the South African private healthcare sector: A cross-sectional comparative study
Authors: Laubscher Anchen , Rodseth Reitze N. , Retief Francois , Saville Adrian 
Published: February 2025

Background
Every healthcare clinical event aims to create value at a certain cost. This value has been defined as the outcome achieved (the degree to which a care event achieved a clinical goal) divided by the cost incurred (determined by the combined price charged by the care provides) to generate the outcome. Subsequently, patient experience has been included as a third factor contributing to value of care, but its value and relationship relative to clinical outcome and event cost is not well understood. This cross-sectional comparative study explored the relative importance of 1) clinical outcome, 2) event cost, and 3) patient experience as they relate to the value of care in the South African private healthcare context.

Materials and methods
Using a value perspectives survey, healthcare consumers (n = 662) and healthcare providers (n = 318) distributed 100 points between the three factors according to how they perceived their value. They were then asked to assess the value of the three factors across six clinical scenarios progressing in clinical severity.

Results
For all scenarios, all participants valued patient experience above event cost, but lower than clinical outcome. However, there were significant differences between consumers and providers in the relative value assigned to each of the three factors. These values changed as the severity of the surgical and medical scenarios changed. Patient experience was consistently assigned a higher value than event cost, thereby making a strong argument for its inclusion into the healthcare value equation.

Conclusion
Both South African healthcare consumers and providers assigned significant value to patient experience across a range of clinical scenarios. These findings suggest that patient experience should be included as a factor in the Value Care Index (VCI) where VCI = (Outcome ÷ Cost) x Patient Experience.
Data-driven insights into interhospital care fragmentation: Implications for health policy and equity among older adults
Authors: Ghazalbash Somayeh , Zargoush Manaf , Verter Vedat , Perri Dan 
Published: February 2025

Objective
To determine factors leading to interhospital care fragmentation (ICF); evaluate how ICF affects rehospitalization costs, length of stays (LOS), and delayed discharge; and analyze ICF disparity among equity-seeking groups.

Materials and methods
We used a 13-year retrospective cohort of older adults (65+) in Ontario, Canada. Utilizing multivariable logistic regression, we identified characteristics associated with ICF and determined its association with outcomes.

Results
Discharge to facilities except home and homecare and travel distance were the strongest risk factors for ICF. Patients were less likely to experience ICF if they were older, frail, or had multiple comorbidities. ICF was strongly associated with an increase in the daily costs of readmission. Moreover, the risks of a prolonged LOS after ICF and delayed discharge were higher among returning surgical patients. The rural residency was a source of health inequality.

Conclusions
ICF exacerbates health disparities and worsens patient outcomes. Our study identified several risk factors associated with ICF, some of which are controllable, paving the way for interventions to mitigate this issue. To promote health equity and reduce adverse outcomes, policymakers should focus on policies for reducing care discontinuity, particularly addressing the controllable risk factors.
Communication between parents of autistic children and health professionals: constraints and prospects for improvement
Authors: Mahboub Abdelaziz , Nisrin El Mlili , Yassin Razkaoui 
Published: February 2025

Autism Spectrum Disorders are a complex set of neurodevelopmental disorders, characterized by a qualitative alteration in social interaction, verbal and non-verbal communication, and restricted, stereotyped behavior. To remedy this communication deficit, a partnership between parents of autistic children and healthcare professionals is essential for the successful medical and psychological care of these children. The expertise of parents would help to improve the identification of the child's difficulties and resources by the care team, with a view to listing elements that are unrecognizable and unobservable within the care structures. To develop a bibliographical review aimed at understanding the constraints to communication between parents of children with autism and healthcare professionals, while proposing prospects for improving this partnership. This is a bibliographical study carried out in two databases, PubMed and Google Scholar. The inclusion criteria concerned articles in French and English published up to 2024 using the keywords “parents of autistic children”, “communication”, “barriers”, “constraints”, “health professionals”, “care”, “Prise en charge”. 20 articles were selected. The main constraints to communication between parents of children with autism and professionals in care facilities are related to health literacy about autism and the perception of each of the therapeutic partners in the care of children with autism. For healthcare staff, several studies report a lack of knowledge about autism, a lack of training and work overload. They also note a poor use of communication techniques, accentuated by cultural differences between parents and healthcare professionals, leading to a divergence in their perception of this disability. As for the parents, they report a high level of stress and a deterioration in their quality of life. This parental stress remains an experience influenced by parents' expectations and mistaken beliefs about the disorder. What's more, parents of children with autism, because of their need for social and emotional support and their difficulty in understanding information conveyed in technical language by healthcare professionals, experience a lack of trust in care providers. To improve communication between autism therapeutic partners, it is crucial to strengthen the training of healthcare professionals so that they are better equipped to interact with families, implement strategies to reduce parents' stress, and increase their level of health literacy. Communication between parents of children with autism and healthcare professionals is undeniably the cornerstone of the success of the child's therapeutic project. However, several constraints often hinder this essential communication. Strategies for improvement must be adopted in order to establish a constructive dialogue and foster an environment conducive to the development of the autistic child.
PENERAPAN REGRESI SPLINE TRUNCATED DATA LONGITUDINAL DUA VARIABEL PREDIKTOR UNTUK PEMODELAN HARGA SAHAM PERBANKAN

Published: February 2025

Stock prices movement are influenced by several factors, including inflation and the exchange rate. The bank is one of the institutions that needs to pay attention to those factors. In this study, analysis of factors that affect stock price can be carried out with the spline truncated approach. The advantage of spline is being able to estimate the data pattern and adjusts to its movement. Stock prices tend to increase and decrease at certain sub-intervals, thus these can be applied in spline truncated. Spline truncated best model for longitudinal data with two predictor variables is determined by choosing the order and optimal knots using the smallest MSE (Mean Square Error). This study used monthly data from January 2019 to December 2022 with a comparison of in sample data and out sample data, which is 90%:10%. The results of the analysis showed the best model obtained on the 2nd orde with 3 knot points. The value is 97.49%, meaning that the model is strong and the MAPE value is 12.71%, which is means that the model has good forecasting ability because it is in the category of 10% ≤ MAPE <20%.
Krize ontologie – výzva edukace
Authors: Černý Michal 
Published: February 2025

Studie vychází z reflexe současné dominantní filosofie edukace jako atomisticky redukovaného chápání skutečnosti. Tato redukce byla v době průmyslové revoluce a rané moderny mimořádně produktivní, ale současně vede k omezené schopnosti edukačně vhodně reflektovat komplexní fenomén. Studie se v tomto bodě opírá především o koncepty nepředmětného a předmětného myšlení u Hejdánka. Východisko vidí v pojetí ontologie procesuální a ekologické, tak jak o ní uvažují Šíp, Lakoff a Latour. Studie se opírá o Kuhnův model vývoje vědy a vychází z něj v analýze dvou – v prostředí školy existujících – fenoménů, totiž globální ekologické krize a formování identity, ve kterých důraz na entitní pojetí vede k nemožnosti se s těmito fenomény vypořádat. Závěrečná část studie upozorňuje na vybrané konceptualizace, které vedou k možnosti opuštění pouze atomistické redukce ontologického popisu světa a nabízejí perspektivy více multiparadigmatického, procesuálního chápání edukace.
Molecular dynamics study of the dissolution of crystalline and amorphous nickel nanoparticles in aluminium
Authors: Poletaev Gennady M. , Rakitin Roman Y. , Zorya Irina V. 
Published: February 2025

Abstract
The dissolution of a nickel nanoparticle in aluminium under the conditions of the crystalline and amorphous state of aluminium and nickel, which can be achieved, in particular, with severe plastic deformation of the powders of the initial mixture (mechanoactivation), was studied by means of molecular dynamics. It is shown that the state of the aluminium structure (crystalline or amorphous) has a relatively small effect on the intensity of mutual diffusion of Ni and Al up to the melting temperature of aluminium. This is due to the formation of a crystalline aluminium layer around the crystalline particle, which repeats the Ni lattice. In the case of the amorphous state of the nickel particle and the aluminium matrix, dissolution occurred much faster than in the crystalline state of nickel. That is, mutual diffusion occurs significantly more strongly in the case of the amorphous state of nickel compared to the case of amorphous aluminium at the same constant temperature. The diameter of the nickel nanoparticle in the considered range from 4 to 12 nm did not affect the temperature at which the mutual diffusion of Ni and Al sharply accelerated with varying temperature. This was due to the fact that the melting point of aluminium did not change when simulating particles of different sizes.

Abstract

Background
The highly infectious coronavirus disease 2019 (COVID-19) is caused by severe acute respiratory syndrome coronavirus 2, the seventh coronavirus. It is the longest pandemic in recorded history worldwide. Many countries are still reporting COVID-19 cases even in the fifth year of its emergence.

Objective
The performance of various machine learning (ML) and deep learning (DL) models was studied for image-based classification of the lungs infected with COVID-19, pneumonia (viral and bacterial), and normal cases from the chest X-rays (CXRs).

Methods
The K-nearest neighbour and logistics regression as the two ML models, and Visual Geometry Group-19, Vision transformer, and ConvMixer as the three DL models were included in the investigation to compare the brevity of the detection and classification of the cases.

Results
Among the investigated models, ConvMixer returned the best result in terms of accuracy, recall, precision, F1-score and area under the curve for both binary as well as multiclass classification. The pre-trained ConvMixer model outperformed the other four models in classifying. As per the performance observations, there was 97.1% accuracy for normal and COVID-19 + pneumonia-infected lungs, 98% accuracy for normal and COVID-19 infected lungs, 82% accuracy for normal + bacterial + viral infected lungs, and 98% accuracy for normal + pneumonia infected lungs. The DL models performed better than the ML models for binary and multiclass classification. The performance of these studied models was tried on other CXR image databases.

Conclusion
The suggested network effectively detected COVID-19 and different types of pneumonia by using CXR imagery. This could help medical sciences for timely and accurate diagnoses of the cases through bioimaging technology and the use of high-end bioinformatics tools.
Waste newspaper activation by sodium phosphate for adsorption dynamics of methylene blue
Authors: Hao Yeo Shi , Othman Norasikin , Ahmad Zaini Muhammad Abbas 
Published: February 2025

Abstract
This study investigates the potential of using waste newspaper (WN) as an adsorbent for removing methylene blue (MB) dye from water, emphasizing the environmental benefits of repurposing waste materials. Activated carbon (AC) was synthesized from WN using sodium phosphate (NaH2PO4) as the activating agent, which is known for producing high mesopore content and requiring relatively low activation temperatures. The activated carbon’s physicochemical properties were thoroughly characterized using techniques such as FTIR, SEM, and surface area analysis based on the Brunner-Emmett-Teller (BET) theory. The specific surface area of AC was 917 m2/g. Continuous adsorption experiments were conducted to evaluate the efficiency of the synthesized activated carbon in a dynamic flow system. Various operating conditions, including initial dye concentration, influent flow rate, and bed height, were explored to optimize the adsorption process. This study applied the Yoon-Nelson, Thomas, Adams-Bohart and modified Logistic models to analyze the breakthrough curves and predict adsorption capacities. Results demonstrated that the AC exhibited high adsorption capacity (14.7 mg/g), particularly at lower flow rates and higher bed heights. This work offers valuable insights into sustainable wastewater treatment methods, showcasing the effectiveness of using low-cost, waste-derived activated carbon for dye removal in industrial applications.

Published: February 2025

Abstract
Medieval manuscripts are an essential part of Persian cultural heritage and a rich source of the country’s material culture. Their study sheds light on shared materials across the Mediterranean and Near East. The practice of using blue and purple in manuscripts was popular during the Middle Ages in both Europe and Persia. Persian historical treatises describe a blue dye plant used for paper, in addition to blue indigo, although its specific terminology was previously unknown. The plant is identified as Chrozophora tinctoria (L.) A. Juss., also known as turnsole; the dye extracted from it is commonly known as folium. This study is divided into three phases: First, dye extraction techniques from C. tinctoria fruits were studied based on historical Persian recipes. Second, methods for reconstructing blue-purple paper dyes from turnsole fruits were explored, with local plants harvested in Iran during August and September, and the dyes analysed using spectroscopy, finding a good agreement to folium spectra obtained from European (central Italy) fruits of C. tinctoria. Third, folium was identified on manuscripts produced under Islamic rule in the Middle Ages. The findings suggest discussion as to whether this dye was used in Persian manuscripts too, given the notable corpus of citations in Persian historical treatises.
Autism and Medical Complexity Among Children in the United States
Authors: Smith Philip H. , Shea Lindsay L. , Rast Jessica E. , Hino Lauren , Briskey Corey , Schendel Diana E. 
Published: February 2025

BACKGROUND AND OBJECTIVES
Ongoing systems-level changes aim to better identify and remedy the unmet health care needs of children with medical complexity (CMC). In tandem, home- and community-based services are expanding to support autistic children and their families. Despite the potential for overlap, CMC and autistic children are treated independently in services, research, and policy. We estimated the overlapping prevalence of CMC and autism among US children and health care expenditures for autistic CMC in comparison with other children.

METHODS
We analyzed 2 national cross-sectional surveys: the National Survey of Children’s Health (NSCH; 2017–2018, 2019–2022, and 2021–2022) and the Medical Expenditures Panel Survey (MEPS; combined 2010–2021), selecting for children aged 0 to 17 years. CMC were defined using 2 different algorithms varying in stringency.

RESULTS
In the most recent 2021 to 2022 NSCH (n = 103 748), the prevalence of CMC among autistic children was 59.28% (95% CI, 55.61%–62.84%) using one algorithm and 17.56% (95% CI, 14.41%–21.24%) using the more stringent algorithm. Forty-one percent of CMC were autistic using either algorithm. In the MEPS data (n = 55 637), autistic CMC had significantly greater median health care expenditures compared with other CMC and other autistic children.

CONCLUSIONS
There is extensive overlap of CMC and autism among children in the United States. When medical complexity and autism are both evident, expenditures are significantly higher than for either category alone. Despite this overlap and the associated high need, CMC and autism are generally treated as separate groups in services, research, and policy. These findings underscore the importance of cohesively understanding service needs across CMC, autistic children, and their caretakers.
Investigation of quaternary ammonium compound resistance in Staphylococcus aureus strains isolated from several foods and food production facilities

Published: February 2025

AbstractQuaternary ammonium compounds (QACs) are the most significant disinfectants utilised to control the contamination of Staphylococcus aureus in food establishments. S. aureus is a significant pathogen that carries genes responsible for resistance to QACs, which pose a risk to public health and food safety. The objective of the study was to investigate the prevalence of QAC genes (qacA/B, qacC, qacG, qacH, qacJ, and smr) and benzalkonium minimal inhibitory concentration (MIC) values in S. aureus strains isolated from food products and food production facilities (n = 200). The analysis results indicated that the qacC gene was the most frequently detected, with a prevalence of 12%. The qacA/B, qacG, qacH, qacJ, and smr genes were identified at frequencies of 2%, 3%, 1%, 4.5%, and 5%, respectively. The highest MIC level was identified in the surface sample, which carried the qacG gene, at a concentration of 6.25 μg mL−1. The study's results highlight the potential risks associated with disinfectant resistance in food establishments. To prevent the transfer of disinfectant resistance genes, which have become a global risk, it is imperative that the rules of disinfectant usage are observed rigorously and that scientific research in this field is diversified.
