Abstract
objective
Bone and muscle diseases are both highly prevalent in aging adults but results from previous studies examining the relationship between sarcopenia and its components with osteoporosis are inconsistent. This study aimed to evaluate the association between sarcopenia and its components with osteoporosis in elderly postmenopausal women.
Materials & Methods
This study is based on cross-sectional data from the Fracture RISk Brussels Epidemiological Enquiry (FRISBEE), involving 3560 community-dwelling post-menopausal women initially included between 2007 and 2013. Randomly selected subjects were reassessed 10 years after inclusion with an evaluation of body composition by dual X-ray absorptiometry (DXA), with a medical questionnaire and a complete geriatric assessment. The diagnostic criteria for sarcopenia were low muscle mass < 5.5 kg/m2, low muscle strength < 16 kg, and low gait speed < 0.8 m/s according to the European Working Group on Sarcopenia in Older People (EWGSOP2). Osteoporosis was defined by the National Bone Health Alliance Working Group proposed extended criteria including a history of major osteoporotic fracture and high fracture risk.
Results
Among the 500 women included, with a median age of 77.4 (74.7–81.8) years, 178 (35.6%) were osteoporotic. Significant correlations were shown between sarcopenia components and bone mineral density (BMD) at all sites as well as trabecular bone score (TBS). The strongest correlations were between handgrip strength and distal forearm BMD (r = 0.27; p < 0.001), and between appendicular lean mass index (ALMI) and total hip BMD (r = 0.36; p < 0.001). Significant differences were observed between sub-groups of osteoporotic status: the handgrip strength, short physical performance battery (SPPB) test, gait speed, and ALMI were significantly lower in osteoporotic subjects (p < 0.001). After adjustment for all covariates, handgrip strength and gait speed were still significantly associated with osteoporosis with an odds ratio of 0.92 (0.88–0.97) and 0.33 (0.11–0.96), respectively. Handgrip strength under 16 kg showed a 2.2-fold higher risk of osteoporosis after adjustment for all covariates.
Conclusion
Sarcopenia, as defined by EWGSOP2, and its components, particularly handgrip strength and gait speed, were significantly associated with osteoporosis. The trabecular bone score, a surrogate for bone microarchitecture, was also significantly associated with all sarcopenia components. Therefore, it should be taken into consideration when evaluating bone health and fracture risk in routine geriatric clinical practice.

Abstract

Back ground
: Schistosomiasis, caused by Schistosoma mekongi, remains public health concern on islands in the Khong district, Champasack province, Southern Lao PDR. Other helminth infections, including Opisthorchis viverrini, hookworm, and Trichuris trichiura, are also prevalent on these islands. This study aimed to assess the impact of an Eco-health/One-health intervention package combined with mass drug administration (MDA) on these helminth infections.
Methods
We conducted a community intervention using a stepped-wedge trial approach on two endemic islands (Donsom and Donkhone) of the Kong district, Champasack province, Lao PDR, between April 2012 and March 2013. After the baseline (T0), the eco-health/one-health intervention package was implemented on Donsom (intervention) and Donkhone island (control). An assessment was conducted in 2014 (T1), one year after the completion of intervention implementation, to assess the short-term impact of the Eco-health/One-health intervention package on helminth infections and compare intervention and control islands. Later in 2015, the Eco-health/One-health intervention package was implemented on control island (Donkhone). After the implementation of intervention, the parasitological assessments were conducted annually in humans in 2015 (T2), in 2016 (T3) and in 2017 (T4), and in dogs in 2017 (T4) to evaluate the long-term impact of the intervention on helminth infections.
Results
Results showed that the Eco-health/One-health intervention package significantly reduced the infection with S. mekongi by 9.0% compared to the use of mass drug administration alone (control island). Additionally, this intervention package significantly reduced O. viverrini infection by 20.3% and hookworm by 17.9%. Annual parasitological assessments between 2012 and 2017 showed that the eco-health/one-health intervention package, coupled with MDA, steadily reduced the prevalence of S. mekongi on the intervention island from 29.1–1.8% and on the control island from 28.4–3.1%, respectively.
Conclusion
The study findings suggest that the Eco-health/One-health intervention significantly contributes to the prevalence reduction of S. mekongi and helminth co-infections, particularly hookworm and T. trichiura. Therefore, implementing the Eco-health/One-health intervention in schistosomiasis-endemic areas could accelerate the achievement of national goals for transmission interruption by 2025 and elimination by 2030.

Published: April 2024

Abstract
Imidst the rapid development of society and economy, we are inevitably confronted with the recurrent challenges of accidents and disasters. However, the continuous advancement in science and technology, particularly the breakthroughs in the field of laser technology, has provided us with robust support to tackle these challenges. Modern laser technology, acclaimed as the magical "sword" capable of effortlessly "cutting iron like mud," has demonstrated unparalleled efficacy in the domain of rescue and demolition. Its precise and swift cutting capabilities have significantly reduced the risk of casualties in rescue operations, shortened the critical time required for demolition tasks, and greatly enhanced the efficiency and precision of the work. The application of this technology not only highlights the immense potential of technological innovation but also offers invaluable support and assurance for our rescue efforts in emergency situations. To explore the application of laser cutting technology in rescue and demolition, this paper focuses on Q235 steel plates with thicknesses of 8mm and 15mm, conducting laser cutting experiments with a fiber laser at a long distance to investigate its suitability for rescue and demolition. The experimental results indicate that the optimal cutting effects are achieved when the distance between the laser head and the workpiece is 10m with a cutting speed of 2.00mm/s and a laser power of 10kW, and when the distance is 13m with a cutting speed of 2.25mm/s and a laser power of 13kW. Appropriately selecting the cutting speed and laser power is crucial for enhancing the surface quality of the cut on Q235 steel plates and reducing the occurrence of root slag, which is essential to meet the demands of the rescue and demolition field.
Estimation method for geometric stability during shoe-type centerless grinding of rolling bearing parts
Authors: Zakharov Oleg , Grigoriev Sergey , Li Chen 
Published: April 2024

Abstract
Centerless grinding is one of the most productive machining methods and is used in the mass production of automotive parts and rolling bearings. Shoe-type centerless grinding allows precise machining of the outer and inner shaped surfaces of bearing rings. Reducing tolerances on the size and shape of bearing parts requires improved centerless grinding. The most difficult thing is to ensure the roundness is less than 1 mm. This requires the development of mathematical models of a high degree of adequacy. This paper presents a new estimation method for geometric stability based on computer simulation. A mathematical model of centerless location on shoes with the high degree of adequacy to the real process has been developed. The main innovations of the developed method were a numerical algorithm for searching for points of contact between the part and the shoes and equation for determining the center of the part as the point of intersection of the trajectory of its movement along the opposite shoes. Based on computer modeling, the trajectories of movement of the profile points were studied and the patterns of geometric stability were established. An evaluation indicator is proposed in the form of the maximum trajectory error of the profile point during one full turn of the part. The possibility of optimizing machining by setting up shoe angles has been confirmed. Experimental verification confirmed high geometric stability due to the shoes location according to the new model.

Published: April 2024

Abstract

Background
In forest ecosystems, biological decomposition of deadwood components plays a pivotal role in nutrient cycling and in carbon storage by enriching soils with organic matter. However, deciphering the functional features of deadwood microbiomes is challenging due to their complexity and the limitations of traditional cultivation methods. Our study demonstrates how such limitations can be overcome by describing metagenome composition and function through the analysis of long DNA molecules using the PacBio HiFi platform.
Results
The accuracy of PacBio HiFi long-read sequencing emerges as a robust tool for reconstructing microbial genomes in deadwood. It outperformed the routine short-read sequencing and genome sequencing of isolates in terms of the numbers of genomes recovered, their completeness, and representation of their functional potential. We successfully assembled 69 bacterial genomes representing seven out of eight predominant bacterial phyla, including 14 high-quality draft MAGs and 7 nearly finished MAGs. Notably, the genomic exploration extends to Myxococcota, unveiling the unique capacity of Polyangiaceae to degrade cellulose. Patescibacteria contributed to deadwood decomposition processes, actively decomposing hemicellulose and recycling fungal-derived compounds. Furthermore, a novel nitrogen-fixing bacteria within the Steroidobacteriaceae family were identified, displaying interesting genomic adaptations to environmental conditions. The discovered diversity of biosynthetic gene clusters highlights the untapped potential of deadwood microorganisms for novel secondary metabolite production.
Conclusions
Our study emphasizes new contributors to wood decomposition, especially Polyangiaceae and Patescibacteria for complex and easily decomposable organic matter, respectively. The identification of nitrogen-fixing capabilities within the Steroidobacteraceae family introduces novel perspectives on nitrogen cycling in deadwood. The diverse array of observed biosynthetic gene clusters suggests intricate interactions among deadwood bacteria and promises the discovery of bioactive compounds. Long read sequencing not only advances our understanding of deadwood microbial communities but also demonstrates previously undiscovered functional capacities of the deadwood microbiome. Its application opens promising avenues for future ecological and biotechnological exploration of microbiomes.

Published: April 2024

Abstract

Background
Diabetes can cause chronic microvascular complications such as diabetic retinopathy (DR) and diabetic nephropathy (DN). DR and DN can lead to or exacerbate diabetic macular edema (DME). Hemodialysis (HD) is the main treatment method for patients with end-stage kidney disease (ESKD) secondary to DN.
Purpose
The aim of this prospective cohort study was to determine the changes in retinal and choroidal thickness in patients with ESKD before and after HD and the impact of long-term HD on DR.
Methods
Eighty-five eyes of 44 DR patients with ESKD who underwent HD were examined by swept-source optical coherence tomography angiography (SS-OCTA). Based on OCTA images, the characteristics of DR and the prevalence of DME in these patients were analyzed. Changes in central retinal thickness (CRT), central retinal volume (CRV), subfoveal choroidal thickness (SFCT) and subfoveal choroidal volume (SFCV) within 30 minutes before and after HD were compared. CRT, CRV, SFCT and SFCV were compared before HD and before the next HD.
Results
There was no significant difference in the average CRT (251.69 ± 39.21 µm vs. 251.46 ± 39.38 µm, P = 0.286) or CRV (0.15 ± 0.62 µm vs. 0.15 ± 0.63 µm, P = 0.324) between before and after HD. After HD, SFCT (243.11 ± 77.15 µm vs. 219.20 ± 72.84 µm, P < 0.001) and SFCV (0.15 ± 0.10 µm vs. 0.13 ± 0.90 µm, P < 0.001). significantly decreased. There was no statistically significant difference in CRT (251.69 ± 39.21 µm vs. 251.11 ± 38.47 µm, P = 0.206), CRV (0.15 ± 0.62 µm vs. 0.15 ± 0.61 µm, P = 0.154), SFCT (243.11 ± 77.15 µm vs. 245.41 ± 76.23 µm, P = 0.108), or SFCV (0.15 ± 0.10 µm vs. 0.16 ± 0.10 µm, P = 0.174) before HD and before the next HD. On en face OCTA images, eighty-five eyes (100%) had retinal nonperfusion areas, focal avascular zone (FAZ) enlargement, and abnormal retinal microvasculature. Based on cross-sectional OCTA images, retinal neovascularization (RNV) was confirmed in 42 eyes (49.41%), and intraretinal microvascular abnormalities (IRMAs) were detected in 85 eyes (100%). Seventeen eyes (20%) still had DME, and all had cystoid macular edema (CME). Among eyes with DME, the epiretinal membrane (ERM) was present in 7 eyes (8.24%).
Conclusions
For DR patients with ESKD who have undergone long-term HD, the choroidal thickness still changes significantly before and after HD, which may be related to short-term effects such as reduced blood volume and plasma osmotic pressure caused by HD. Although HD can improve DME, the DR of patients with ESKD should still be given attention.

Abstract
Purpose
Ovarian cancer is the deadliest of all gynaecological malignancies, making it a major public health concern. Major global research finding highlighted a low level of ovarian cancer knowledge and education among women of reproductive age. The study assessed knowledge, perception, and intended healthcare-seeking behaviour for ovarian cancer among female undergraduate students of University of Ibadan.
Methods
This cross-sectional survey involved 275 female undergraduate students of the University of Ibadan selected by a four-stage sampling technique. A semi-structured self-administered questionnaire was used to obtain data on their socio-demographic characteristics, knowledge, perception, and intended healthcare-seeking behaviour toward ovarian cancer. Data was analysed using Chi-square, Spearman’s rank order correlation, Mann-Whitney U and Kruskal-Wallis H tests with α ≤ 0.05.
Results
Age was 22.12 ± 2.2 years and 76% were Christians. Majority (95.3%) were aware of ovarian cancer however, only 33.2% had good knowledge. The top-two identified symptoms were abdominal pain (66%) and pelvic pain (63.8%). Over two third, (68.3%) had poor knowledge of its risk factors. Having ovarian cysts (29.5%) was the commonly recognized risk factor while the least was “menopause” (16.4%). Majority had moderate perceived susceptibility and severity, but high perceived benefits, cues to action and self-efficacy. The majority (80.2%) intended to visit the health facility once they notice any symptoms of ovarian cancer and (66.0%) plan to do so within a few days. Knowledge was significantly and positively correlated with perception, the strongest was with perceived severity (p < 0.001).
Conclusion
The female undergraduate students had low knowledge of ovarian cancer, but high intention to seek medical help. The results highlight the need for multi-component educational interventions and strengthening of the health system.
The “SEP clock”: A discussion of first proton arrival times in wide-spread solar energetic particle events
Authors: Posner A. , Richardson I. G. , Strauss R. D.-T. 
Published: April 2024

Abstract

This work analyzes the appearance of wide-spread deka-MeV solar energetic proton (SEP) events, in particular the arrival of the first protons within ~ 4.5–45 MeV measured at Earth-Sun L1, and their relationship with relative solar source longitude. The definition of “wide-spread SEP event” for this study refers to events that are observed as a 25 MeV proton intensity increase at near-1 AU locations that are separated by at least 130ᵒ in solar longitude. Many of these events are seen at all three of the spacecraft, STEREO A, STEREO B, and SOHO, and may therefore extend far beyond 130ᵒ in longitude around the Sun. A large subset of these events have already been part of a study by Richardson et al. (2014). The event source region identifications draw from this study; more recent events have also been added. Our focus is on answering two specific questions: (1) What is the maximum longitude over which SEP protons show energy dispersion, i.e., a clear sign of arrival of higher-energy protons before those of lower energy? (2) What implications can be drawn from the ensemble of events observed regarding either direct magnetic connectivity to shocks and/or cross-field transport from the site of the eruption in the onset phase of the event?

Published: April 2024

Abstract
With the rapid development of Internet technology, a massive amount of English text has emerged, creating an urgent need to evaluate the semantic similarity of these texts across different domains. Existing research on semantic similarity faces the challenge of insufficient prior knowledge. Therefore, a new method has been proposed, called Knowledge Prior Topic Model (KPTM), for analyzing text semantic similarity. This method incorporates semantic relationship data from the large-scale English knowledge base, Probase, into the topic model and combines it with an effective keyword serialization approach to calculate the hybrid measurement of concepts and keywords for text similarity. Experimental results demonstrate that the proposed method contributes to improving semantic similarity and outperforms other models in comparative experiments.

Abstract

The brain-computer interface (BCI) based on steady-state visual evoked potential (SSVEP) has gained increasing attention due to its non-invasiveness, low user training requirement, and high information transfer rate. In order to enhance the performance of SSVEP detection, we propose an improved joint model that combines variational mode decomposition (VMD) and wavelet fusion with filter bank canonical correlation analysis (FBCCA). The model is validated on awearable SSVEP-BCI dataset. By integrating decomposition and denoising techniques, the model employs DFA thresholding and applies deep filtering using discrete wavelet transform (DWT) and wavelet packet transform (WPT) to denoise the wearable EEGs. The filtered components are reconstructed along with the components that do not require filtering. Subsequently, identification is conducted using FBCCA, which employs a combination of filters to delineate frequency bands. Ultimately, the classification accuracy for dry and wet electrodes reaches 72.46% and 88.29% respectively. Compared to existing research results on this dataset, dry and wet electrodes show improvements of around 13% and10% respectively. This hybrid model provides a new perspective for wearable SSVEP recognition research and holds high potential for widespread application.

Published: April 2024

Abstract
Background: Myopia has shown a sharp upward trend worldwide and has become a global public health concern. However, there were insufficient correction rates all over the world. This study aimed to investigate the prevalence of myopia and spectacle-wearing rate in primary and high school students in Yicheng, as well as analyze the risk factors of myopia onset and development.
Methods: The Yicheng Myopia Study was a school-based cross-sectional study of primary and high school students in Yicheng District, Shandong Province, China. The refractive error was measured using an autorefractor without cycloplegia and recorded as a spherical equivalent refraction (SER). Visual acuity was recorded as uncorrected visual acuity (UCVA). Only worse SER and UCVA values between the two eyes were analyzed. Myopia was defined as SER < -0.50 D and UCVA > 0.2 using the logarithm of the minimum angle of resolution. Correction rate (CR) was the ratio of individuals wearing spectacles in myopia students.
Results: A total of 37,908 primary and high school students were included (16,826 girls, mean age of 11.68 ± 3.04 years). In total, 15,779 students were myopic. Older age, female sex, and schooling in urban areas were risk factors for myopia. Correction rates were low among students in Yicheng. And there were obvious relative visual acuity insufficiency among low and moderate myopia students, especially in high grades students.
Conclusions: The prevalence of myopiain the Yicheng student population was 41.6%. The proportion of students with uncorrected myopia was high.Further research should be conducted to identify specific socioeconomic factors that contribute to myopia and to lower the incidence of myopia by lowering the exposure to these factors.
Trial registration: Not applicable.
