Abstract
Introduction:
The association between cardiovascular disease (CVD) and bone metabolism has been extensively investigated. The cardiac metabolic index (CMI) is a new indicator of cardiovascular metabolism. Our study aimed to explore the relationship between CMI and lumbar bone mineral density (BMD) in adults.
Methods
This population-based study investigated the relationship between CMI and lumbar BMD in adults, using data from the National Health and Nutrition Examination Survey (NHANES) 2011–2018. CMI is computed as the conduct of TG(Triglyceride) (mmol/L)/HDL-C(high-density lipoprotein cholesterol)(mmol/L) ratio and waist(cm)/height(cm) ratio (WHtR). Weighted multivariate linear regression and smoothed curve fitting were employed to examine linear and non-linear associations between CMI and lumbar BMD. Threshold effects were determined using a two-part linear regression model. Additionally, subgroup analyses and interaction tests were conducted to assess the stability of the relationship between CMI and lumbar BMD in different demographic contexts.
Results
Multivariate linear regression analysis revealed a significant negative association between CMI and lumbar BMD [β = −0.01, 95% CI: −0.02, − 0.01]. This negative correlation remained consistent across all subgroups, encompassing age, gender, ethnicity, and diabetes status. Furthermore, a U-shaped relationship between CMI and lumbar BMD was observed, with an inflection point of 1.26 (log likelihood ratio < 0.01). When CMI was less than 1.26, the association between CMI and lumbar BMD was negative [β=-0.03, 95% CI= (-0.05, -0.02)], while when CMI was greater than 1.26, the association between CMI and lumbar BMD was positive [β = 0.02, 95% CI= (-0.01,0.05)].
Conclusions
In adults, there is a negative association between CMI and lumbar BMD.

Abstract
Purpose:
Older men have higher prostate-specific antigen levels than younger men. However, the current Japanese Urological Association guidelines recommend secondary screening at a cutoff value of 4.0 ng/mL, even in older men. Here, we reexamined the cutoffs for older men using a prostate screening cohort in Japan, and first performed an analysis to determine the indication cutoffs for detecting positive biopsies.
Methods:
Data from 68,566 prostate cancer screenings in the city in 2018 were combined with cancer registration data. The optimal prostate-specific antigen levels to predict prostate cancer in different age groups were calculated using receiver operating characteristic curves after determining whether a cancer was registered within one year of screening.
Results:
At the conventional prostate-specific antigen threshold of 4.0 ng/mL, the sensitivity, specificity, and negative predictive value were 94.9%, 91.7%, and 91.7%, respectively. The optimal prostate-specific antigen cutoff values for patients aged 50–59 years, 60–69 years, 70–79 years, and over 80 years were 3.900 ng/mL, 4.014 ng/mL, 4.080 ng/mL, and 4.780 ng/mL, respectively.
Conclusions:
The sensitivity and specificity of prostate cancer screening in the city were high, indicating a highly accurate screening. The prostate-specific antigen threshold was 4.78 ng/mL in patients older than 80 years. A higher prostate-specific antigen threshold may be useful in men over 80 years to avoid excess biopsy and reduce costs. Our results suggest that the Japanese current method of using PSA 4.0 ng/mL as a cutoff regardless of age may not be preferable in the older men.

Abstract

Using coping theory, this research creates and evaluates a process model to investigate the sequential mediating roles of perceived Covid-19 threat (PC-19 threat) and death anxiety on the relationships between migration stress, psychological distress, and prolonged grief disorder (PGD) among Afghan refugees who migrated to Pakistan and China after the Afghan war. The proposed model for Study 1 proved fully supported and demonstrated that migration stress has significant positive association with perceived psychological distress (β = 0.39, p < .001). Furthermore, significant relationship between migration stress and psychological distress is significantly mediated first by PC-19 threat and then significantly by death anxiety. Study 2, incorporated time-lag datasets technique to investigate the sequential moderating effect of resistance. Additionally, study 2 found that migratory stress was strongly associated with PGD (β = 0.21, p < .01). It was also articulated that resilience significantly moderated migration stress’s sequential indirect effect on psychological distress and PGD. The implications and future objectives of the study have been highlighted.

Abstract
Edge banding plays a critical role in contemporary panel furniture production, as its quality significantly affects the aesthetic appeal of furniture. However, the current method of quality inspection and classification relies primarily on manual inspection and screening, which can be time-consuming, subjective, and lead to inaccurate and inefficient detection results. To address this issue, this study collected and processed pictures of defects in banded board edges, accurately labeling them into six categories, including open glue, shortage, chipping, uneven trimming, glue line, and banding indentation, using the LabelImg software. The YOLOv7 network architecture was then leveraged to train the network on the accurately processed surface defect dataset of banded edge panels. Subsequently, samples of panels produced through the manufacturing process were analyzed and tested, with the training outcomes effectively visualized and analyzed using the TensorFlow tool, resulting in a mean average accuracy (mAP) rate of 74.8% and an average detection rate of 57.63 FPS. The test findings revealed that the YOLOv7 target detection network successfully identified defects during the production of banded edge panel parts, and thus, improved the accuracy and efficiency of detecting banded edge panel defects. Therefore, this method is feasible and holds immense potential for practical application, as indicated by its capability to immensely enhance the accuracy and efficiency of detecting banded edge panel defects.
Role of Mechanotransduction on Decision Making for Treatment of Chronic Wounds

Published: August 2023

Abstract
Chronic wounds create tremendous clinical, social, and economic burdens that generate frustration within hospitals and outpatient clinics, impair the health-related quality of life of chronic wound patients, and enormously drain healthcare resources. Common wound care and treatment techniques involve the usage of wound dressings. However, although there have been decades of advancements in the wound care field, resulting in the introduction of new, novel wound dressings, there remains a significant number of chronic wounds that fail to fully heal or are recurrent. Few studies consider how the specific mechanical properties of wound dressings influence complex mechanical responses within wound tissue. Mechanotransduction is a biological process that has been shown to influence wound tissue response, signaling cellular processes that alter regeneration and wound repair. The objective of this study is to take an initial step to determine and interpret the extents to which biophysical wound dressing properties impact mechanotransduction within a wound tissue. Current experimental techniques make it challenging to investigate many of the complexities of the wound healing process. Thus, the purpose of this study is to begin with computational models and theoretical descriptions that propose predictions and explanations of the role of various mechanical wound dressing characteristics on mechanotransduction in wound tissues. Three-dimensional models of wound tissue and wound dressings have been developed to analyze how von Mises stresses are distributed within the tissue models. The results of this study support that the shape, thickness, length, and stiffness of wound dressings impact the stress transmitted to the wound tissue. Our results show that shorter (7 cm in length) ellipsoid dressings lead to highest stresses within the wound tissue where dressing’s thickness and stiffness don’t show a significant impact. However, in ticker ellipsoid dressings (11 cm in length), higher stresses are observed when dressing is softer and thinner. When using a rectangular dressing, shorter, softer, thinner ones lead to high stress transmission to a wound tissue. The findings suggest that standards regarding biophysical wound dressing parameters, including stiffness, shape, thickness, and size, may be introduced to improve decision making for treatment of chronic wounds. These parameters may be brought to use to elucidate factors predisposing a chronic wound to heal. With an enhanced understanding of dressing properties and how they affect stress response within patient-specific wound tissues, more informed decision making for the treatment and care of chronic wounds can be made with the application of novel, precision dressings.

Published: August 2023

Abstract
Mediastinal infections due to non-tuberculous mycobacteria (NTM) remain an exceedingly rare entity. Most cases in the published literature do not include paediatric patients. Due to their clinical infrequency, poor response to antimicrobial therapy and often precarious anatomical location, the treatment of these lesions presents a challenge. We present four cases of mediastinal NTM infection treated successfully by a multi-disciplinary team approach within a tertiary paediatric centre. All four children had extensive evaluation and ultimately had their disease debulked via thoracotomy in addition to prolonged anti-mycobacterial therapy, with successful clinical outcomes.

Abstract
Backgroud
: The study objective was to compare three-dimensional and two-dimensional imaging using computer-assisted systems (CASs) in clinical guidance for preoperative surgical planning for middle hepatic tumors in children.
Methods
A retrospective analysis was performed on 23 children who underwent surgery for middle hepatic tumors in our hospital from January 2016 to June 2022. The surgical resection plan was formulated by the operator team using two-dimensional CT images before the operation. Then, the same qualified surgeons conducted an in-depth analysis and formulated the surgical resection scheme for the same pediatric patient using three-dimensional imaging of the middle hepatic tumor. The feasibility of the two schemes was compared and analyzed.
Result
All the tumors were successfully removed according to the preoperative method developed using three-dimensional imaging. The postoperative short-term follow-up revealed that all patients were doing well. Preoperative plans were revised in 9 cases after evaluating the three-dimensional images due to the disparity between the original plans and the three-dimensional relationship between the tumor and blood vessels, vascular variation, and the volume of remnant liver.
Conclusions
Three-dimensional imaging with a computer-assisted surgery system is superior to two-dimensional imaging in the preoperative planning of pediatric hepatoblastoma.

Authors: Das Shayeri , Ranjan Prabhat , Chakraborty Tanmoy 
Published: August 2023

Abstract
In recent years, oxide-based nano clusters have shown some significant applications in medical sciences, bio sensing, catalysis, and energy storage. Here we have reported the computational study of oxide-based nano clusters X3O4 (X = Ti, Fe, Zn) by means of Conceptual Density Functional Theory (CDFT) method. Geometry optimization and freqneucy computation of these clusters are carried out using the functional B3LYP / LANL2DZ in the DFT framework. Highest Occupied Molecular Orbital (HOMO) – Lowest Unoccupied Molecular Orbital (LUMO) of the clusters are found between 2.019 eV to 3.570 eV. The global CDFT descriptors viz. hardness, softness, electronegativity, electrophiliicty index and dipole moment are calculated. Result shows that Zn3O4 has the maximum stability whereas Fe3O4 is highly reactive in nature. Electronegatiivty and electrophilicity index of these clusters decrease from Fe3O4 to Zn3O4 to Ti3O4. Analyses are conducted for the optical characteristics of X3O4 nano clusters, comprising their refractive index, dielectric constant, optical electronegativity and IR activity. Refractive index, dielectric constant and range of harmonic frequency increase from Zn3O4 to Fe3O4 via Ti3O4. The estimated bond length, HOMO-LUMO energy gap, refractive index and IR activity of the nano clusters are in agreement with the reported experimental and theoretical results. The physico-chemical properties of X3O4 nano clusters indicate their potential applications in biomedical sciences especialy for the treatment of cancer cells.

Authors: Maswadah M. 
Published: August 2023

Abstract
In this paper, a new technique has been proposed for deriving the prior density for the empirical Bayes by utilizing the characteristic function. For measuring the efficiency of this prior, the mean squared errors and the mean percentage errors are derived for the Burr type-XII model parameter estimates compared to their counterparts based on the informative gamma prior, via Monte Carlo simulations. The simulation results indicated that the characteristic prior provides better estimates and outperforms the informative gamma prior. Finally, a numerical example is given to demonstrate the efficiency of the proposed priors.
UDE-Based Robust Nonlinear Control of the Boost Converter with Constant Power Load
Authors: Oucheriah Said 
Published: August 2023

Abstract
The boost converter feeding a constant power load (CPL) is a non-minimum phase system that is prone to the destabilizing effects of the negative incremental resistance of the CPL and presents a major challenge in the design of stabilizing controllers. In this work, a robust nonlinear controller based on the uncertainty and disturbance estimator (UDE) scheme is successfully developed to tightly regulate the output voltage of the boost converter. A systematic procedure is developed to select the controller gains to achieve a satisfactory output response. Using simulation, the effectiveness of the proposed controller is validated and compared to a recent robust nonlinear controller.

Esta pesquisa apresenta os resultados de uma análise efetuada em obras didáticas aprovadas no Programa Nacional do Livro Didático (PNLD) de 2018 para a disciplina de Física. O objetivo geral consistiu em avaliar como estão sendo apresentados os conteúdos de Física Moderna e Contemporânea (FMC) nesses materiais, evidenciando as principais potencialidades e fragilidades de cada obra. Compuseram o corpus desta pesquisa três obras didáticas escolhidas por escolas públicas estaduais de São Luís – Maranhão. A metodologia aplicada direcionou-se pela abordagem qualitativa e tipologia documental. Os resultados revelam que as obras didáticas analisadas podem ser consideradas boas ferramentas para o processo de Ensino de Física, apesar de algumas não conterem todos os tópicos de FMC relevantes para formação científica e cidadã do aluno. Ficou evidente que dos critérios investigados, a interdisciplinaridade foi contemplada de forma satisfatória. É preciso, contudo, que os professores estejam preparados para suprir as falhas dos livros didáticos, buscando subsídios em outros recursos pedagógicos além do livro, como textos científicos, notícias de jornais e revistas.
The Current Status of the Use of Internet Hospitals for Outpatients With Pain: Retrospective Study
Authors: Sang Ling , Song Li 
Published: August 2023

Background
The national “Internet +” policies and the emergence of internet hospitals have created a new direction for the management of pain outside of the hospital. Nevertheless, there are no consolidated studies conducted by pain physicians on the current state of internet hospital–based online medical services used by patients with pain outside of a hospital setting.

Objective
In this retrospective study, we aimed to examine the status of the use of internet hospitals by patients who experience pain. Moreover, we identified the factors that influenced patients' decisions to make an online visit through the internet hospital.

Methods
Detailed information was collected online and offline from outpatients with pain at the information technology center of West China Hospital of Sichuan University from February 2020 to April 2022. Binary logistic regression analysis was conducted to identify the determinants that influenced patients' decisions to make an online visit to the internet hospital.

Results
Over a 2-year period, 85,266 pain-related clinic visits were recorded. Ultimately, 39,260 patients were enrolled for the analysis, with 12.9% (5088/39,260) having online visits. Both online and offline clinics had a greater number of visits by women than men. The average age of patients attending the online clinic was 46.85 (SD 16.56) years, whereas the average age of patients attending the offline clinic was 51.48 (SD 16.12) years. The majority of online clinic visitors (3059/5088, 60.1%) were employed, and one of the most common occupations was farming (721/5088, 14.2%). In addition, 51.8% (2635/5088) of patients who participated in the online clinics lived outside the hospital vicinity. Young (odds ratio [OR] 1.35, 95% CI 1.01-1.81; P=.045) and middle-aged (OR 1.98, 95% CI 1.81-2.16; P<.001) patients, employed patients (OR 1.11, 95% CI 1.04-1.18; P=.002), nonlocal patients (OR 1.57, 95% CI 1.48-1.67; P<.001), and the ordinary staff (OR 1.19, 95%CI 1.01-1.39; P=.03) were more likely to have the intention to choose online visits through the internet hospitals.

Conclusions
Internet hospitals are flourishing as a more efficient and promising method of pain management and follow-up for patients with pain outside the hospital. People with pain who are young, working, and not in the vicinity of hospitals are more likely to visit internet hospitals.

Published: August 2023

Background
Bisphenol A (BPA), bisphenol S (BPS), and bisphenol F (BPF) are widely used in various consumer products. They are environmental contaminants with estrogenic properties that have been linked to various health outcomes. Understanding their impact on body composition is crucial for identifying potential health risks and developing preventive strategies. However, most current studies have only focused on their relationship with BMI.

Objective
This study aimed to investigate the association between urinary levels of BPA, BPS, and BPF and body composition, including BMI, lean mass, and fat mass, in a large population-based sample.

Methods
We conducted a cross-sectional analysis using data from the National Health and Nutrition Examination Survey 2003-2016. Body composition data were assessed using dual-energy X-ray absorptiometry, which provided precise measurements of lean mass, fat mass, and other indicators. We used multivariate linear regression models to estimate the associations, adjusting for potential confounders such as age, gender, race, socioeconomic factors, and lifestyle variables.

Results
The results revealed significant associations between bisphenol exposure and body composition. After adjusting for covariates, BPS showed a positive association with BMI, with quartiles 3 and 4 having 0.91 (95% CI 0.34-1.48) and 1.15 (95% CI 0.55-1.74) higher BMI, respectively, compared with quartile 1 (P<.001). BPA was negatively associated with total lean mass (TLM) and appendicular lean mass, with quartiles 2, 3, and 4 having –7.85 (95% CI –11.44 to –4.25), –12.33 (95% CI –16.12 to –8.54), and –11.08 (95% CI –15.16 to –7.01) lower TLM, respectively, compared with quartile 1 (P<.001). BPS was negatively associated with TLM, with quartiles 3 (β=–10.53, 95% CI –16.98 to –4.08) and 4 (β=–11.14, 95% CI –17.83 to –4.45) having significantly lower TLM (P=.005). Both BPA and BPS showed a positive dose-response relationship with trunk fat (BPA: P=.002; BPS: P<.001) and total fat (BPA: P<.001; BPS: P=.01). No significant association was found between BPF and any body composition parameter.

Conclusions
This large-sample study highlights the associations between urinary levels of BPA and BPS and alterations in body composition, including changes in lean mass, fat mass, and regional fat distribution. These findings underscore the importance of understanding the potential health risks associated with bisphenol exposure and emphasize the need for targeted interventions to mitigate adverse effects on body composition.
