The Association of β2-Microglobulin with Physical Performance in Chinese Hemodialysis Patients with and without Diabetes
Authors: Zhan Qiu-Nan , Chu Wen-Wen , Guo Qi , Zhao Jun-Li 
Published: December 2024

Background:
Higher β2-Microglobulin (β2-MG) is associated with aging, stroke and cognitive impairment, which are all connected with poor physical fitness. Poor physical function is ascribed to increasing mortality. However, there has been an academic dispute over the association of serum β2-MG with survival rate. Furthermore, diabetes mellitus (DM) has been well linked to poor physical function and a high level of β2-MG. We hypothesized that higher β2-MG could be associated with worse physical performance in hemodialysis (HD) patients, and that association could vary with diabetes.

Methods:
We conducted a multicenter cross-sectional study at seven HD centers in Shanghai and Suzhou, respectively, in China, where a collection was made of the clinical characteristics, laboratory indicator, physical performance and DM assessment. The physical function was measured by the Short Physical Performance Battery (SPPB), and SPPB score ≤9 as the cutoff for low physical performance.The patients were divided into two groups of low and high physical performance, before categorized into four subgroups based on the absence of diabetes and SPPB scores. Logistic regression analyses were conducted to explore the association of β2-MG with physical performance.

Results:
The final analysis involved a total of 780 patients, 251(32.2%) having diabetes. In the total population, β2-MG was lower in those with low SPPB than in those with high SPPB. Only in non-diabetic patients, β2-MG was lower in the low SPPB group, and positively associated with SPPB and its three compenents scores. Regardless of diabetes status, those who had low SPPB were prone to be older, accompanied by the poor nutritional status. Addtionally, the diabetes patients tended to have shorter HD duration and higher body mass index than the non-diabetic patients. Both before and after the covariates adjusted, β2-MG was significantly associated with physical performance in HD patients without diabetes.

Conclusions:
Low level of β2-MG was significantly associated with poor physical performance in Chinese HD patients without DM.

Authors: Chono Toshiharu , Tokutomi Hisashi , Nakamura Kazuma , Miyazaki Koji 
Published: December 2024

Abstract
We report the first spectral reflectance of tungsten carbide (WC) as potential solar selective absorber. We developed an optical measurement system for visible to mid-infrared spectroscopy, covering the range of 0.1–2.5 eV, to evaluate the solar selectivity. A polycrystalline WC was prepared using spark plasma sintering method. The measured spectral reflectance of WC exhibits a low-energy plasma excitation around 0.6 eV corresponding to the cutoff energy of sunlight, consistent with ab initio calculations, thus making it preferable for the solar selective absorber. We also discuss effects of the sample quality on the spectral reflectance.
Effects of terbium concentrations on the characteristics of Ga2O3 films
Authors: Guo Qixin , Koga Yushi , Kawano Yuki , Saito Katsuhiko , Tanaka Tooru 
Published: December 2024

Abstract
This study investigates the incorporation of terbium (Tb) into Ga2O3 films and its influence on their structural, optical, and luminescent properties. Tb doping composition in Ga2O3 films was controlled by adjusting the Tb composition in the targets. X-ray diffraction analysis unveiled lattice expansion as Tb composition increased. Atomic force microscopy images depicted consistently smooth film surfaces across varying Tb compositions. Optical transmission spectra demonstrated high transmittance and direct bandgap transitions, with no notable alteration observed in the bandgap concerning Tb composition. Photoluminescence spectra exhibited characteristic Tb ion emission peaks, with intensities initially increasing before reaching a plateau, attributed to a balance between increased luminescent centers and deteriorated crystal quality. This study significantly enhances our understanding of Tb doping effects in Ga2O3 films and offers valuable insights for their application in optoelectronics.

A GROUNDED THEORY OF EXPERIENCING AND PERCEIVING YOUTH MENTORING AS A PROCESS OF “MIXED EMOTIONS”
Authors: Mulenga-Wincierz Mary 
Published: December 2024

Many youths from disadvantaged backgrounds globally lack positive role models and meaningful relationships with supportive adults within their families and communities. Youths’ involvement in relationships with caring adults, such as mentors, promotes their well-being. However, little is known about youth mentoring relationships in some parts of the world, particularly Zambia. This constructivist grounded theory study aimed to develop a substantive theory that explains the experiences and perceptions of mentors and mentees in Zambia. The sample included mentors and mentees who had been in relationships for at least one year. Semi-structured interviews were conducted with five mentors aged 31 to 68 and four mentees aged 18 to 20. The inductive, iterative and constant comparative method guided the coding, memoing, and theoretical sampling processes and led to the co-construction of four categories. This paper focuses on one category: “Experiencing and perceiving mentorship as a process of ‘mixed feelings’”. Mentees felt mentoring supported their emotional and psychological well-being, which enhanced their resilience and was perceived as a way of surviving. Mentors expressed that mentoring enabled them to support youths beyond their professional roles and enhanced their self-awareness, knowledge and reputation, which increased their self-worth and confidence and the desire to continue changing youths´ lives. Challenges included meeting time issues, ineffective communication, and confusion in differentiating between the mentor´s professional and mentoring roles, which caused difficulty in mentor-mentee interactions. They felt overwhelmed by their mentees´ difficult circumstances and worked with limited resources. They also felt unrecognised and unsupported. Findings suggest priority issues and potential logical solutions, such as preliminary and ongoing mentor training, recognising and supporting youth mentoring, and providing essential primary resources to disadvantaged youths in Zambia to enable effective mentoring.
Design and Application of ISSA-BP Neural Network Model for Predicting Soft Tissue Relaxation Force
Authors: Yong-Li Yan  , Teng Ren  , Li Ding  , Tiansheng Sun  
Published: December 2024

Purpose
Accurate biomechanical modeling is crucial for enhancing the realism of virtual surgical training. This study addresses the computational cost and complexity associated with traditional viscoelastic models by incorporating neural network algorithms, thereby augmenting the predictive capability of soft tissue modeling.
Methods
To address these challenges, the present study proposes a novel biomechanical modeling approach. The approach establishes a relaxation prediction model based on the backpropagation (BP) neural network and optimizes it using an enhanced sparrow search algorithm (ISSA). This hybrid method leverages the dynamic characteristics of forceps to predict the relaxation force of soft tissues more accurately. The ISSA optimizes the model by integrating chaos mapping, nonlinear inertia weight, and vertical-horizontal crossover strategy, which helps overcome the issue of local optima and boosts the predictive performance.
Results
The experimental results demonstrated that the R² values reached 0.9956 for the pig kidney and 0.9896 for the pig stomach, indicating the model's exceptional precision in predicting relaxation forces.
Conclusions
The relaxation force prediction model based on ISSA-BP neural network provides excellent predictive performance, offering a new and effective strategy for biomechanical modeling of soft tissues in virtual surgical systems.
Autopsy-Based Study of Suicidal Deaths Among the Elderly Conducted at Victoria Hospital Mortuary.
Authors: J Cyriac Agnes , S. Venkata Raghava  , Kumar Mukund  
Published: December 2024

Background: Suicide is the act of deliberately killing oneself and it is a significant cause of death in all age groups (1). When comparing the number of attempted and completed suicides, older people have a more significant number of successful suicide than any other age group worldwide (2). 'National Policy on Older Persons'- 1999 defines 'elderly' or ‘senior citizen’ as a person of age 60 years or above (3). NCRB 2020 reported that around 13,126 older people per 100,000 population committed suicide in India (4).
Objectives: This study aims to investigate the demographic characteristics, psychological, and etiological factors associated with elderly suicides, and evaluate the methods used by individuals in this age group to end their lives.
Methods: A cross-sectional study was conducted at Victoria Hospital Mortuary over 18 months (February 2021 to July 2022). Out of 397 autopsies in the study age group, 67 cases of suicide were included based on the inclusion criteria. Information was collected from police reports, family members, and suicide notes, followed by a detailed analysis of autopsy findings.
Results: The study revealed that 77.6% of the victims were male, with the majority falling within the 60-64 age group (40.3%). Hanging was the most common method of suicide (50.7%), followed by poisoning (34.3%). Key contributing factors included psychiatric disorders, predominantly depression (53.73%), chronic physical illness (46.27%), and social isolation or loneliness (32.84%).
Conclusion: Elderly suicide is a multifactorial issue, with psychological distress, chronic illness, and social isolation being the primary contributors. Effective prevention strategies should include early mental health interventions and social support systems tailored to the needs of the elderly.

Authors: Rahnas Abdul Azeez  , Arya Ajayan  , Sheik Shakeer Hussain S  
Published: December 2024

Background: Establishment of identity is a real challenge when dead bodies are burnt, mutilated, or skeletonized. Stature is a very useful tool to establish the identity. Study of estimation of stature from the length of long bones are there in the literature, however the reliability of the formula is not consistent in many instances. The present study is an attempt to establish the relationship between stature and length of distal half of upper limb. Materials and methods: This cross sectional study was conducted on 100 subjects, 50 males and 50 females aged between 21 and 60 years in the department of Forensic Medicine in Govt. Medical College, Thrissur. Results: In males the mean length of distal half of upper limb is 47.64 ± 1.41 cm. and correlation coefficient (r) is 0.8125. In females the mean length of distal half of upper limb is 43.94 ± 2.19 cm. and correlation coefficient (r) is 0.7458. Thus stature is strongly correlated with length of distal half of upper limb. Conclusion: There is significant difference between males and females with respect to both the parameters under study. The higher mean values obtained by males indicated that they have greater stature and length of distal half of upper limb measurements compared to females.

Published: December 2024

Introduction: Road traffic accidents (RTA's) are a leading cause of mortality and a serious injury world wide, with skull fractures frequently emerging as a significant consequence of such incidents. The pattern and distribution of skull fractures can provide valuable insights into the mechanisms of injury and the severity of accidents. Understanding these patterns is crucila for improving both preventive measures and clinical responses.
Materials and methods:This is aretrospective cross-sectional study of one year duration.All the cases of road traffic accident deaths with skull fractires were included in the study. A total of 342 cases of death due to fatal RTA were present and 140 cases had skull fractures.
Results: The commonest site of fracture was the vault, observed in 64.28% of the cases. In fractures involving single bone of vault, frontal bone fractures were seen in the highest number of cases, in 29 cases(32.22%). The MCF was the most commonly involved area in the base of the skull fractures, observed in 7.14% of the cases.
Conclusion: A substantial amount of financial burden is produced on the family of the deceased, on the health care system and as well as on the economic output of the country. Therefore, measures should be sought to reduce the RTA's as a number of positive and correct interventions can bring down their number.

Published: December 2024

В данной статье предлагается разработка двухкаскадного высокоэффективного усилителя с высоким входным импедансом. Исследования показали, что два однокаскадных усилителя с низким коэффициентом усиления занимают меньше места по сравнению с однокаскадным усилителем с высоким коэффициентом усиления для усилителей с емкостной связью. Кроме того, разделение усилителя с высоким коэффициентом усиления на два каскада в данной структуре обеспечивает более высокий входной импеданс.
In this article, proposes the development of a two-stage high-efficiency amplifier with high input impedance. Research has shown that two single-stage low-gain amplifiers occupy less space compared to a single-stage high-gain amplifier for capacitively coupled amplifiers. In addition, dividing the high-gain amplifier into two stages in this structure provides a higher input impedance.
