Authors: Pu Jinsong , Zheng Lin , Jian Changchun 
Published: September 2024

Abstract

This study aimed to evaluate the operative techniques and clinical outcomes of a minimally invasive suture bridge technique for repairing posterior cruciate ligament (PCL) tibial avulsion fractures. A retrospective analysis of 18 patients treated between January 2018 and December 2022 was conducted. The patients, aged 21 to 48 years, underwent arthroscopic surgery with a small posteromedial arc incision. The suture bridge technique was employed for secure fixation, resulting in effective fracture healing and minimal impact on the bone bed. Follow-up, ranging from 12 to 18 months, showed significant improvements in Lysholm and IKDC scores postoperatively. The technique offers a safe and efficient method, particularly suitable for comminuted fractures, with no cases of anchor loosening, refracture, or displacement observed. The minimally invasive nature of the procedure and its adaptability to various fracture types highlight its potential as a promising treatment for PCL tibial avulsion fractures.

Abstract

PURPOSE:
Physical activity measured by accelerometry (PA-accelerometry) is used as an indicator of disease severity in chronic diseases. Currently, only fragmented age ranges of reference percentile curves are available for European children. This study aimed to provide age- and sex-specific percentiles for physical activity measured by hip-worn accelerometry derived throughout the full age range of European children.
METHODS:
Individual-level population-based PA data from HELENA and IDEFICS/I.Family studies were pooled and harmonized. Together these studies involved children aged 2–18 years from 12 European countries. PA was measured using uni-axial or tri-axial Actigraph accelerometers. Accelerometry recording was defined as valid if lasted at least 6 hours on at least 2 weekdays and 1 weekend day. Primary outcomes included averaged counts per minute (CPM), sedentary time (SED), light PA (LPA) and moderate-to-vigorous PA (MVPA). Generalized Additive Models for Location, Scale and Shape were used to derive age- and sex-specific reference percentile curves for these outcomes.
RESULTS:
The combined cohort consisted of 11,645 children aged 2 to 18 years who contributed 14,610 valid accelerometry recordings, with a median accelerometer wear time of 6 days and a median wear time of 745 minutes per day. This dataset allowed for the construction of age- and sex-specific reference percentile curves for CPM, SED, LPA, and MVPA. The curves demonstrated varying trends and variability across age groups.
CONCLUSIONS:
This study provides age- and sex-specific percentile curves for PA-accelerometry in European children, addressing a current gap in the availability of full-age range reference data. These curves based on healthy children can be used by clinicians, researchers, and policymakers to interpret PA-accelerometry measurements, assess severity of disease in paediatric chronic illness, track physical activity trends, and evaluate treatment responses and health interventions.

Published: September 2024

Abstract

Background
The advantages and disadvantages of the two types of operation were discussed by comparing the clinical efficacy of modified bianchi orchiopexy(MBO trans-scrotal midline incision ) and traditional laparoscopic orchiopexy (TLO).
Methods
A retrospective analysis was conducted on 100 cases of palpable cryptorchidism admitted to our hospital from October 2021 to October 2022. Patients were categorized into the MBO group (n = 50) and TLO group (n = 50) based on the surgical approach. The differences in the rate of operation success,operation time,hospitalization expenses and postoperative complications were compared between the two groups.
Results
The MBO group demonstrates a surgery success rate of 94%, while the TLO group achieves a success rate of 96%, with no statistically significant difference (P > 0.05). The differences in surgical duration and hospitalization expenses between the two groups are statistically significant(P < 0.05). Regarding postoperative complications, the MBO group exhibits 2 cases of testicular retraction, and the TLO group has 3 cases, but the difference is not statistically significant (P > 0.05). Neither group of patients experiences testicular atrophy, inguinal hernia, hydrocele, scrotal hematoma, nor encounters poor wound healing.
Conclusion
Both surgical methods are equally safe and effective. The transscrotal incision offers advantages in terms of surgical duration,hospitalization expenses and aesthetic appeal compared to the traditional laparoscopic surgery incision, aligning more with the concept of minimally invasive procedures,thus warranting clinical promotion.

Published: September 2024

Abstract

Esophageal cancer is one of the most common cancers worldwide, especially esophageal squamous cell carcinoma, which is often diagnosed at a late stage and has a poor prognosis. This study aimed to develop an algorithm to detect tumors in esophageal endoscopy images using innovative artificial intelligence (AI) techniques for early diagnosis and detection of esophageal cancer. We used white light and narrowband imaging data collected from Gachon University Gil Hospital, and applied YOLOv5 and RetinaNet detection models to detect lesions. We also verified the generalizability of the models using external data collected from various institutions. The results showed that the AI models showed high precision and sensitivity in white light and narrowband images, and the RetinaNet model performed well, analyzing not only polyps but also superficial esophageal cancer. This study demonstrates an effective method for detecting esophageal tumors through AI-based esophageal endoscopic image analysis and is expected to help researchers develop AI models that combine real-time image-based detection and synthesis algorithms to predict the depth of lesion invasion. These results and efforts are expected to significantly reduce misdiagnosis rates, enhance the effective diagnosis and treatment of esophageal cancer, and promote the standardization of medical services.

Published: September 2024

Abstract

This work presents an application of co-simulation technology, the interaction between two simulations, acting in sync, considering Multi-Body Dynamics (MBD) and Finite Element Method (FEM) to a biomechanics case of study. Several approaches are available in literature for the modelling and simulation of complex systems, examining also the interaction among different domains through a multi-physics approach. This work is related to the modelling, simulation and test of MBD-FEM co-simulation technology applied to the human walking, in the presence of a hip prosthesis, providing insights for the development of a method for designing, analyzing, and studying a human prosthesis. Usually and traditionally, the hip prosthesis analysis and design are performed by considering static loads only. In this paper we explore the co-simulation technique to combine the MBD of the walking to the FEM of the hip prosthesis to analyze the effect of dynamic loads acting in an interacting environment. The promising results asset the great potential this technology holds, and the necessity, for the prosthesis designers, to carefully consider the multi-physical properties of the problem, allowing design choices that are coherent with the problem.

Abstract

Background: Continuous cropping of the same crop leads to land degradation. This is also called the continuous-cropping obstacle. Currently, intercropping flue-cured tobacco with other crops can serve as an effective strategy to alleviate continuous cropping obstacles.
Results: In this study, flue-cured tobacco K326 and insectary floral plants were used as materials, and seven treatments of flue-cured tobacco monoculture (CK), flue-cured tobacco intercropped with Tagetes erecta, Vicia villosa, Fagopyrum esculentum, Lobularia maritima, Trifolium repens, and Argyranthemum frutescensrespectively, were set up to study their effects on rhizosphere soil chemical properties and composition and structure of rhizosphere soil microbial community of flue-cured tobacco. 16 S rRNA and ITS amplicons were sequenced using Illumina high throughput sequencing. Flued-cured tobacco/insectary floral plants intercropping can influence rhizosphere soil chemical properties, which also change rhizosphere microbial communities. The CK and treatment groups flue-cured tobacco rhizosphere soil microorganisms had significantly different genera, such as intercropping T. repens and A. frutescens significantly increased the number of Fusarium and intercropping T. erecta, V. villosa, L. maritima, T. repens, and A. frutescens significantly increased the number ofSphingomonas and norank_f_Gemmatimonadaceae. Additionally, intercropping T. erecta, V. villosa and L. maritima changed the rhizosphere fungal and bacterial community and composition of flue-cured tobacco and the positive correlation between flued-cured tobacco rhizosphere the genera of fungi and bacterial were greater than CK. The pathway of the carbohydrate metabolism, amino acid metabolism, and energy metabolism in rhizosphere bacteria were significantly decreased after continuous cropping. Fungal symbiotic trophic and saprophytic trophic significantly increased after intercropping V. villosa, L. maritima and plant pathogen and animal pathogen were increased afterintercropping T. repens and A. frutescens. Additionally, bacterial and fungal communities significantly correlated with soil chemical properties, respectively.
Conclusion: Based on the results, we may provide new insights into improving barriers to continuous cropping of flue-cured tobacco via intercropping approach to regulate the rhizosphere environment, which would allow us to facilitate translation to more effective measures.

Published: September 2024

Abstract

The agriculture sector in China plays an important role in the country’s economy and provides a crucial foundation for achieving and maintaining food security. Anhui Province has a unique geographical location, with the Huaihe River as the boundary, forming three different geological features, resulting in a variety of agricultural production methods. Therefore, the investigation into the effectiveness of agricultural production in Anhui Province has a wide range of reference significance. To explore the regional disparities in the effectiveness of agricultural output in Anhui Province’s various regions, using a three-stage DEA model, this research analyzes the efficiency and output of agricultural production in 16 cities in Anhui Province in 2021. In addition, a three-stage dynamic analysis is performed using the Malmquist index to demonstrate the dynamic shifts in agricultural production efficiency across different prefecture-level cities in Anhui Province between 2017 and 2021. By comparing and analyzing the data after two three-stage adjustments, it is discovered that the agricultural production efficiency of 16 cities has changed obviously, and there is a big gap between them. Therefore, targeted policies should be formulated according to the actual situation. Due to the unique geographical structure of Anhui Province, this study provides a new analytical method to solve the problem of agricultural production efficiency. This method can be applied to other countries or other departments.

Published: September 2024

Abstract

Condition-based maintenance (CBM) involves making decisions on maintenance or repair based on the actual deterioration conditions of the components. The long-run average cost is minimized by choosing the right maintenance action at the right time. In this study, considering the uncertainty of health status cognition and the limitation of detection information, the digital twin is introduced into the maintenance decision method to realize the intelligent operation and maintenance of mechanical equipment and parts by simulating the CBM decision-making problem as a continuous semi-Markov decision process (CSMDP). For tool wear, the application of a reinforcement learning (RL) algorithm based on the digital twin in CBM is described. The convergence of the digital twin and RL algorithm is used to learn the optimal maintenance decisions and inspection schedule based on the current health state of the component.
Optimization of Toilet Bowl Ventilation technology for odor control and energy efficiency enhancement in public toilet

Published: September 2024

Abstract

Public toilets frequently use considerable amounts of ventilation to ensure appropriate air quality while operating. This obviously results in energy loss and reduces the thermal comfort of the area in the winter. To optimize and improve the ventilation of traditional toilets, this paper uses the computational fluid dynamics (CFD) simulation methods to qualitatively and quantitatively analyze the performance of toilet bowl ventilation (TBV) technology under different airflow, odors, and commode models, as well as to compare the exhaust effect of different ventilation schemes and the energy-saving performance of TBV technology. The wind direction for both models was toward the toilet’s inside. Even if the highest mass concentration above the allowable limit, the iso-surface demonstrates that all extra odor volume is controlled inside the toilet bowl. The results show that the application of TBV technology in public toilets can reduce the airflow to 10m3/h during the toilet used and still meet the air quality and energy-saving requirements. This method has a thermal energy saving efficiency of 8.2W/°C. This investigation may efficiently reduce air heat dissipation caused by the ventilation process and fan power consumption while assuring effluent discharge, thereby establishing a foundation for the promotion and use of the TBV technology.
Suppression of the DNA repair enzyme NEIL2 promotes persistent inflammation and genomic damage in subjects with stable COPD and during severe exacerbations

Published: September 2024

Abstract

Background.
Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory airway disease that is an independent risk factor for lung cancer. NEIL2, a DNA glycolase involved in DNA repair during transcription, has also been associated with an increased incidence of malignancies in humans. NEIL2 knockout mouse models have demonstrated increased inflammation and oxidative DNA damage in the lungs after exposure to an inflammatory insult, but data are lacking regarding NEIL2 function in individuals with stable COPD and during severe acute exacerbations of COPD (AECOPD). We investigated whether NEIL2 levels and oxidative DNA damage to the transcribed genome are altered in individuals with stable COPD and AECOPD.
Methods
The study was conducted at a single center in the US. Eligible subjects underwent a one-time 30 cc venous blood draw. The population consisted of 50 adults: 16 with stable COPD, 11 hospitalized for AECOPD, and 23 volunteers. We analyzed blood leukocytes for NEIL2 mRNA and DNA damage by RT‒qPCR and LA‒qPCR, respectively, in all groups. Plasma levels of seven biomarkers, CXCL1, CXCL8, CXCL9, CXCL10, CCL2, CCL11 and IL-6, were analyzed in the COPD groups using a magnetic bead panel (Millipore®).
Results.
The NEIL2 mRNA levels were lower in individuals with stable COPD and AECOPD than in controls (0.72 for COPD, p = 0.0289; 0.407 for AECOPD, p = 0.0002). The difference in NEIL2 mRNA expression between the stable COPD group and AECOPD group was also statistically significant (p < 0.001). The fold change in DNA lesions per 10 kb of DNA was greater in the stable COPD (9.38, p < 0.0008) and AECOPD (15.81, p < 0.0004) groups than in the control group. The difference in fold change was also greater in the AECOPD group versus stable COPD p < 0.0236). Biomarker levels were not significantly different between the COPD groups. NEIL2 levels were correlated with plasma eosinophil levels in the stable COPD group (r = 0.737, p < 0.0027).
Conclusions.
NEIL2 mRNA levels are significantly reduced in COPD subjects and are associated with increased DNA damage and inflammation. These results reveal a mechanism that promotes persistent airway inflammation and oxidative genomic damage and increases the risk of malignancy in this population.
Micro Aluminum-Air Batteries for Extended Operational Duration of Small-Scale Quadrotors

Published: September 2024

Abstract

Small-scale quadrotors, typically defined as centimeter-scale in size and tens of grams in weight, are increasingly being utilized in applications such as agricultural monitoring or search and rescue operations. These vehicles are typically powered with lithium-ion batteries. However, vehicle operational efficiency and capability are often compromised by the limited energy density of these batteries, resulting in short operational duration. This work explores a high-energy chemistry, aluminum-air (Al-air), as a power source to significantly extend the operational duration of small-scale quadrotors. Rapid corrosion of the aluminum anode in existing Al-air systems has been a barrier to adoption in applications where long-term operation is required. However, corrosion is less of a concern in the small-scale quadrotor application, where the battery is typically under continuous use over a short period of time. The electrochemical and packaging design of a micro-Al-air pouch cell battery is optimized for two operating points: an energy density of 325 Wh/(kg_battery ) above a power density of 500 W/(kg_battery ), and an energy density of 240 Wh/(kg_battery ) above a power density of 800 W/(kg_battery ), both of which far surpass the performance of equivalent commercial lithium-ion batteries. A 3D-printed small-scale quadrotor platform is used to evaluate flight duration. The micro Al-air battery delivers 13.1 minutes of flight time, compared to the 4.5 minutes of flight time provided by the commercial micro lithium-ion battery. This work demonstrates the feasibility of Al-air batteries that simultaneously possess sufficiently high power density to achieve small-scale quadrotor flight, and sufficiently high energy density to achieve extended duration of that flight.
