Postoperative Outcomes of Total Humerus Replacement for Oncologic Reconstruction of the Upper Limb
Authors: Gonzalez Marcos R. , Werenski Joseph O. , Lozano-Calderon Santiago A. 
Published: May 2024

Background:
Total humerus replacement (THR) is a reconstruction procedure performed after resection of massive humeral tumors. However, there is limited literature on the rates of failure and functional outcomes of this implant. Our study aimed to determine the main failure modes, implant survival, and postoperative functional outcomes of THR.

Methods:
A comprehensive search of the PubMed and Embase databases was conducted. We registered our study on PROSPERO (448684) and used the Strengthening the Reporting of Observational Studies in Epidemiology checklist for quality assessment. The Henderson classification was used to assess endoprosthesis failure and the Musculoskeletal Tumor Society (MSTS) score for functional outcomes. Weighted means and standard deviations were calculated.

Results:
Ten studies comprising 171 patients undergoing THR were finally included. The overall failure rate was 32.2%. Tumor progression (12.6%) and prosthetic infections (9.4%) were the most common failure modes, followed by soft-tissue failures (5.9%), aseptic loosening (3.5%), and structural failure (1.8%). Two-year, 5-year, and 10-year implant survival rates for the entire cohort were 86%, 81%, and 69.3%. Ten-year implant survival for primary THRs was 78.3%, compared with 38.6% for revision THRs (p = 0.049). The mean MSTS score at the last follow-up was 77%. Patients whose implants did not fail had a higher MSTS score (79.3%) than those with failed implants (71.4%) (p = 0.02).

Conclusion:
One-third of THR will fail, mostly due to tumor progression and prosthetic infection. Overall functional scores were acceptable, with MSTS scores displaying great hand and elbow function but limited shoulder function.

Exploring the Influence of Seismic Source and Improvement Methods on Tunnel Seismic Prediction
Authors: Lu Xinglin , Wang Wei , Yang Chao , Hu Xuquan , Liao Xian , Fu Zhihong 
Published: May 2024

Abstract
Tunnel seismic advanced prediction method is essential for detecting abnormal bodies ahead of the tunnel face and minimizing risks during tunnel construction. Selecting the seismic source plays a crucial role in influencing the precision and effectiveness of data acquisition. At present, tunnel seismic data is usually collected using explosive and sledgehammer sources. Nevertheless, the various sources are located in different positions within the tunnel excavation zone, resulting in distinct characteristics observed on the surface and reflected waves in the acquired tunnel seismic data. The explosive source has minimal surface wave interference, but it is expensive. However, the sledgehammer source is economical yet plagued by inadequate energy and substantial surface wave disruption. Regrettably, there is a lack of research on seismic sources in tunnels, which impairs the precise interpretation of forecasting conclusions from these sources. This paper seeks to investigate how various sources impact tunnel seismic prediction and suggests a new method that integrates data acquisition and processing from these sources. The explosive source is used once, while the sledgehammer source is used 24 times. Cross-correlation calculations are conducted to enhance the resolution of sledgehammer source data, reducing surface wave interference, based on seismic data obtained from the explosive source. Extensive numerical simulations and tunnel experiments support the validity of this method, highlighting its potential to lower data acquisition expenses and enhance tunnel seismic prediction accuracy.

Authors: Gholizade Vajihe , Saffari Amir , Ahmadabadi Ali , Karam Amir 
Published: May 2024

Abstract

The vulnerability of the Mashhad aquifer has been analyzed by spatial analysis approach using DRASTIC, SI, GODS and SINTACS models. The Mashhad aquifer in northeast Iran is now considered a critical area due to its special circumstances, the presence of industrial and agricultural activities, and large settlements. This study aims to evaluate the vulnerability zones of the Mashhad aquifer using four models DRASTIC, SI, GODS and SINTACS. The parameters of the models are explained and measured by GIS capabilities. After weighting, ranking, and integrating the layers in the ArcGIS software, we have produced vulnerability maps of the aquifer. The results have indicated that in the DRASTIC model, the study area is categorized into five vulnerability zones very low (5.81%), low (26.03%), moderate (44.45%), high (22.57%), and very high (1.13%). In the SI model, the study area is categorized into five vulnerability zones very low (0.40%), low (24.63%), moderate (23.98%), high (18.71%), and very high vulnerability (32.25%). In the GODS model, it is categorized into five vulnerability zones very low (0.93%), low (31.11%), moderate (11.45%), high (1.56%), and very high (54.95%). In the SINTACS model, the area is also categorized into the vulnerability five zones very low (0.44%), low (25.57%), moderate (28.58%), high (2.79%), and very high (42.61%). For validating the results, the vulnerability maps have been compared with the TDS quality index. The results showed that all four models have high accuracy in categorizing the vulnerability of the Mashhad aquifer. The comparison among the results of the models has indicated that the vulnerability of the aquifer generally increases from southeast to northwest and then decreases from the central region towards the northwestern areas.
Therapeutic effect of small-dose remifentanil infusion on severe emergence agitation after general anesthesia for major abdominal surgery in adults: Study protocol for a randomized and controlled trial (RF-TEA Trial)
Authors: Wang Li-Qing , Wu Pin , Yang Hui-Qi , Zhu Ye-Ke , Wu Jun-Chao , Yao Yong-Xing 
Published: May 2024

Abstract

Background
Emergence agitation (EA) after general anesthesia is one of the most common complications in the postanesthesia care unit (PACU). However, there are still no currently established guidelines for the treatment of EA in adults. Previous studies have shown that continuous infusion of remifentanil during recovery has a preventive effect on the occurrence of EA. One report showed that remifentanil can reduce the recurrence rate of moderate EA, but no studies have evaluated the therapeutic effects of remifentanil on severe EA and circulating cytokine levels. This study aims to observe the therapeutic effect of small-dose remifentanil infusion on severe EA and circulating cytokine levels in adult patients who underwent major abdominal surgery.
Methods
In this randomized controlled clinical study, we will enroll a total of 80 adult patients aged 18–75 years who underwent hepatobiliary and pancreatic surgery and had American Society of Anesthesiologists classification I-III severe EA in the PACU. Severe EA was defined as a score of ≥ 6 using the Riker Sedation-Agitation Scale. Patients will be randomized at a 1:1 ratio into two groups, receiving either a bolus of 1 µg/kg remifentanil injection followed by a 0.1 µg/kg·min infusion in the remifentanil group or the same volume of normal saline in the control group. The primary objective is to observe the therapeutic effect of remifentanil on severe EA in adults after general anesthesia in the PACU. Circulating cytokine concentrations will be determined during the emergence period.
Discussion
There is no currently established method for the treatment of EA. Previous studies have focused on the preventative effect of remifentanil on EA. There are no studies on the therapeutic effect of remifentanil on severe EA. To our knowledge, this will be the first randomized and controlled trial conducted to observe the therapeutic effect of small-dose remifentanil infusion on severe EA after general anesthesia for major abdominal surgery in adult patients and on circulating cytokine concentrations during the emergence period.

Analysis of bolt bonding surfaces by the finite element method based on the equivalent Iwan model
Authors: Sun Litai , Li Ling 
Published: May 2024

Abstract

Aiming at the force-displacement relationship and its energy dissipation of the bolted bonding surface under the action of small-amplitude tangential displacement, a finite element model with the Iwan model is established and used to investigate the stiffness and energy dissipation phenomena of the bolted bonding surface. First, the force-displacement relationship of the Iwan model is converted into stress-strain relationship through the hybrid hardened intrinsic model, and the subroutine based on UMAT and UHARD realizes the elastic-plastic change of the Iwan model during the contact of the bonding surface in the finite-element model of the stress-strain representation; then, the three-dimensional modeling and the joint simulation of the subroutine are carried out by using the ABAQUS finite-element software; finally, through the experimental data, the validity is verified, and the effects of multiple factors on the bolt bonding surface are analyzed. Finally, the validity is verified by experimental data to analyze the influence of multiple factors on the force-displacement relationship of the bolt bonding surface, and the polynomial function of the loading and unloading curves is established by using the interpolation fitting method to explore the energy dissipation phenomenon of the bolt bonding surface. The results show that the finite element method can accurately reflect the hysteresis and energy dissipation phenomenon of the force-displacement relationship of the bonding surface, and has the ability to investigate the relevant influencing factors. Through this study, it provides a basis for the study of the finite element method of the bolt bonding surface.
The relationship between Alexithymia and aggressive behavior: the mediating role of perceived stress
Authors: Wei Changjiao , Fan Xianglin , Xu Yan 
Published: May 2024

Abstract

Individuals with alexithymia, due to the fragmentation of cognitive and emotional components in their behavioral sequences, tend to interpret cues in a hostile manner and exhibit maladaptive behaviors such as aggression. The disconnect between subjective stress evaluation and autonomic response may exacerbate these externalized behavioral problems. However, this perspective has not been sufficiently validated in the college student population. The current study measured 754 college students in northern China using validated scales for alexithymia, aggressive behavior, and perceived stress. The results revealed a significant positive correlation between alexithymia and perceived stress, aggressive behavior(t = 0.602,t = 0.410,P < 0.001), the direct predictive effect of alexithymia on aggressive behavior was significant (B = 0.574, t = 12.191, P < 0.001).This finding supports the notion that alexithymia can influence an individual's predisposition towards aggressive behavior. Furthermore, the study explored the mediating role of perceived stress in this relationship. Perceived stress, the predictive effect of alexithymia on aggressive behavior remained significant (B = 0.363,t = 6.284, P < 0.001) after the introduction of the mediating variable. The indirect effect, mediated by perceived stress, is 0.145, accounting for 36.62% of the total effect. The findings provide valuable insights into the complex interplay between alexithymia, aggressive behavior, and perceived stress in college students, which can guide future research and interventions aimed at reducing aggressive behavior in this population.
Impacts of biochar-based amendment on soil cadmium immobilization, rice grain cadmium accumulation and yield
Authors: Han Junnan , Wu Donghai , Yang John , Li Zhengguo 
Published: May 2024

Abstract

Cadmium (Cd) contamination in soil is of severe health and environmental concern because of its threat to human health, food safety, and ecosystem sustainability. The in situ stabilization of Cd has been recognized as a potentially economical technique for the rehabilitation of soil polluted with Cd. Biochar has recently received much attention as an eco-friendly and recyclable soil amendment, which is more beneficial for plant growth, soil health, and restoration of contaminated soil. An experiment was performed in the field to study the efficiency of three different types of biochar: maize straw biochar, bamboo biochar, and coconut shell activated carbon in combination with rape organic fertilizer (ROF), calcium magnesium phosphate fertilizer (CMPF), and fulvic acid (MFA), respectively, on soil Cd immobilization, Cd uptake by rice, and rice yield. The experiment indicated that the biochar-based amendments reduced soil Cd bioavailability and rice Cd content by 9.58%-27.06% and 19.30%-71.77%, respectively. The transformation of exchangeable Cd (Ex-Cd) to carbonate bound Cd (Ca-Cd), Fe-Mn oxide bond (Ox-Cd), and residual (Re-Cd) in soil accounted for the mitigation of Cd absorption and enrichment by rice. In addition, the biochar-based amendments altered soil physicochemical properties and promoted soil health. Biochar-based amendments enhanced Fe and Mn plaques by 47.31%-160.34% and 25.72%-73.09%, respectively. The correlation analysis revealed that leaf Cd and Fe/Mn plaques primarily controlled Cd uptake by rice, and soil pH, Eh, CEC, SOC, Fe/Mn plaques, and TP influenced Cd bioavailability in soil. This field study demonstrated that maize straw and bamboo biochar-based amendments had a higher benefit and were potentially applicable to ameliorating metal-contaminated agricultural soil.

Published: May 2024

Abstract

Background: Periodontal health in men with HIV remains understudied, despite suggestions of associations between HIV infection and gingival pocketing, periodontal attachment loss, and gingival inflammation. As antiretroviral therapy (ART) has improved the quality of life for people living with HIV (PLWH), aging-related risk factors and comorbidities, including periodontitis, have emerged. This study aims to assess alveolar bone height, gingival crevicular fluid (GCF) cytokines, and periodontal disease activity in men with and without HIV.
Methods: Ninety-three men (50 HIV+, 43 HIV-) aged 35-70 years were recruited from Columbia University Irving Medical Center clinics. Periodontal examination, GCF collection, and intraoral radiographs were conducted.
Results: While no significant differences were observed in bleeding on probing, clinical attachment loss and pocket depths, men with HIV exhibited significantly greater alveolar crestal height on radiographs compared to men without HIV (HIV + 3.41+/-1.35 mm, HIV- 2.64+/-1.01 mm; p = 0.004), reflecting greater alveolar bone loss. GCF IL6 levels showed a trend towards elevation in men with HIV (HIV + 0.349+/-0.407 pg/ml, HIV- 0.220+/-0.228 pg/ml; p = 0.059).
Conclusions: Men with HIV demonstrate increased alveolar bone loss compared to those without HIV, possibly mediated by elevated IL6 levels. These results underscore the importance of comprehensive oral health management in PLWH and highlight the need for further research understanding the mechanisms linking HIV infection, cytokine dysregulation, and periodontal health.

Abstract

Background
Years of life lost (YLL) is a measure of fatal burden, quantifying the toll associated with premature death. YLL is an important and useful metric for assessing the mortality impacts of the COVID-19 pandemic. In this study, we calculated the fatal burden associated with COVID-19 and other causes of death in Australia from 2019 to 2022.
Methods
The analysis was conducted using demographic and death data contained within the Person Level Integrated Data Asset. The study population included all deaths which occurred between 2019 to 2022 in Australia that were received and registered by the Australian Bureau of Statistic (ABS) by 31 March 2023. We calculated YLL using the 2019–2021 Australian life tables published by the ABS, which provided more contemporary single-age and gender breakdowns of aspirational life expectancy than standard reference life tables found in the Global Burden of Disease studies.
Results
Between 2019 and 2022, the fatal burden in Australia increased from an age-standardised YLL of 74.14 per 1,000 population in 2019 to 80.88 per 1,000 population in 2022, an increase of 9.1%. However, this increase was not linear, with a slight decrease observed in 2020, followed by a rise to baseline in 2021 and a continued increase in 2022. Throughout the four-year period, the YLL per 1,000 population in males was consistently around 1.5 times that observed for females, though females experienced a higher proportional increase in total fatal burden between 2019 and 2022 (10.1% in females compared to 8.8% in males). Fatal burden from COVID-19 increased considerably between 2020 to 2022. In 2022, based on age-standardised YLL per death, COVID-19 was the third leading cause of fatal burden in Australia, following cerebrovascular diseases and ‘other cardiac conditions’ (cardiac disease that is not coronary artery disease). The only conditions which showed a reduction in fatal burden in 2022 compared to 2019 were influenza and pneumonia and chronic lower respiratory diseases.
Conclusions
Our findings contribute to improving our understanding of the mortality impacts of the COVID-19 pandemic in Australia and how these have evolved over time. The results highlight areas of health where COVID-19 has had a disproportionate impact, which can support the implementation of more targeted and nuanced public health measures.

Abstract

Tightly coupling Gigawatt-scale wind- and solar-sourced H2 with industry depends on the ability to store and deliver otherwise-curtailed H2 during times of shortages. Thousands of tonnes of H2 will require storage in regions where subsurface storage is scarce, which may only be possible using liquid organic H2 carriers. Herein, we evaluate the scale and operation of aboveground systems storing and delivering otherwise-curtailed H2 using TOL/MCH at 50,052 locations in the United States suitable for Gigawatt-scale wind- and solar-powered electrolyzer systems. Modeling results suggest that the levelized cost of storage is highly spatially heterogeneous, with minor impact on the cost of H2 in the Midwest, and potentially significant impact in areas with emerging H2 economies such as Central California and the Southeast. While TOL/MCH may be the cheapest aboveground bulk storage solution evaluated, upfront capital costs, modest energy efficiency, reliance on critical materials, and greenhouse gas emissions from heating remain concerns.
