ZusammenfassungFragestellung Ein vorzeitiger Behandlungsabbruch stellt eines der häufigsten Probleme in der stationären Entgiftungsbehandlung dar. Die vorliegende Studie ist der Frage nach der Rolle motivationaler Faktoren nachgegangen.Methode Es wurden 85 PatientInnen neben den routinemäßig erhobenen Befunddaten, zum Zeitpunkt der Aufnahme als auch der Entlassung verschiedene Fragebögen zur Symptomschwere psychischer Störungen, Funktionsbeeinträchtigungen sowie Veränderungsmotivation vorgelegt.Ergebnisse PatientInnen, die die Behandlung abgeschlossen haben, gaben eine signifikant höhere Veränderungsmotivation an, als PatientInnen, die die Behandlung vorzeitig abgebrochen haben. Dabei hatte die Contemplations-Phase einen prädiktiven Wert (OR: 3,472) auf einen Behandlungsabbruch. Eine erfolgreich absolvierte Behandlung reduziert signifikant die Symptomschwere psychischer Störungen sowie Funktionsbeeinträchtigungen. Auf der Ebene der Veränderungsmotivation zeichnet sich ein signifikanter Zuwachs.Schlussfolgerung Neben den bekannten Risiken für einen Abbruch scheint die messbare Veränderungsmotivation zu Beginn der Behandlung einen möglichen Marker für den Behandlungsverlauf darzustellen. Implikationen für die klinische Praxis werden abgeleitet.

Abstract
Background During the COVID-19 outbreak in Italy, only fast-track endoscopic procedures have been performed; nevertheless, a significant drop in their number has been reported. We evaluated whether the pandemic has impacted the appropriateness and diagnostic yield of fast-track endoscopic procedures compared with those performed in 2019.
Methods This retrospective study involved endoscopy services in Northern Italy. We compared data regarding endoscopic procedures performed in March and April 2020 with those performed during the same period in 2019.
Results In 2020, there was a 53.6 % reduction in the number of fast-track endoscopic procedures compared with 2019. Patients undergoing endoscopy in 2020 were younger than in 2019. Both appropriate referral and diagnostic yield increased in 2020 for both upper and lower endoscopy. A higher rate of cancer was diagnosed in 2020 by upper endoscopy (3.6 % vs. 6.6 %; P = 0.04).
Conclusions The high level of inappropriate endoscopy referrals registered in 2019 significantly improved during the COVID-19 outbreak of 2020, with an increase in the diagnostic yield.

AbstractObjective The aims of this study were to describe the elastosonographic findings of the patellar ligament in healthy dogs >15 kg in different positions and determine the most appropriate stifle angle to perform elastosonography of the patellar ligament.Study Design Eighteen clinically healthy dogs, weighing >15 kg, were prospectively recruited. B-mode ultrasound and real-time elastosonography of both patellar ligaments were performed on days 0 and 14. Elastosonography examinations were performed with the stifle in four positions: standing position, lateral recumbency with the stifle positioned at 135 degrees extension and in full passive flexion and extension.Results The percentage hardness of the patellar ligament was significantly lower when the elastosonographic examination was performed with the dog standing, compared with the other positions (p < 0.005). The variability in the elastosonography readings for each stifle position was lowest when the dog was standing (89.32%).Conclusion Elastosonography is a feasible technique for evaluating the elasticity of the normal canine patellar ligament in dogs >15 kg and would be a useful technique for investigating the mechanical changes within the patellar ligament following stifle surgery. Elastosonography of the patellar ligament should be performed with the dog standing to provide the most accurate elastosonograms with lowest variability between readings.

Published: September 2020

AbstractMultiligament knee injury (MLKI) typically requires surgical reconstruction to achieve the optimal outcomes for patients. Revision and failure rates after surgical reconstruction for MLKI can be as high as 40%, suggesting the need for improvements in graft constructs and implantation techniques. This study assessed novel graft constructs and surgical implantation and fixation techniques for anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), posterior medial corner (PMC), and posterior lateral corner (PLC) reconstruction. Study objectives were (1) to describe each construct and technique in detail, and (2) to optimize MLKI reconstruction surgical techniques using these constructs so as to consistently implant grafts in correct anatomical locations while preserving bone stock and minimizing overlap. Cadaveric knees (n = 3) were instrumented to perform arthroscopic-assisted and open surgical creation of sockets and tunnels for all components of MLKI reconstruction using our novel techniques. Sockets and tunnels with potential for overlap were identified and assessed to measure the minimum distances between them using gross, computed tomographic, and finite element analysis-based measurements. Percentage of bone volume spared for each knee was also calculated. Femoral PLC-lateral collateral ligament and femoral PMC sockets, as well as tibial PCL and tibial PMC posterior oblique ligament sockets, were at high risk for overlap. Femoral ACL and femoral PLC lateral collateral ligament sockets and tibial popliteal tendon and tibial posterior oblique ligament sockets were at moderate risk for overlap. However, with careful planning based on awareness of at-risk MLKI graft combinations in conjunction with protection of the socket/tunnel and trajectory adjustment using fluoroscopic guidance, the novel constructs and techniques allow for consistent surgical reconstruction of all major ligaments in MLKIs such that socket and tunnel overlap can be consistently avoided. As such, the potential advantages of the constructs, including improved graft-to-bone integration, capabilities for sequential tensioning of the graft, and bone sparing effects, can be implemented.

Published: September 2020

Introduction Coronavirus disease 2019 (COVID-19) has become a world pandemic since early 2020. The complexity of handling multiple myeloma (MM) has increased substantially during this pandemic. The objective of this review is to know the current recommendation to manage MM in the COVID-19 era.
Materials and Methods Electronic databases, including PubMed central and PubMed, were used to conduct a literature search. It was conducted on May 18, 2020, using the keywords “multiple myeloma” AND “COVID-19” AND “Prevalence OR Impact OR treatment OR prophylactic.” The included articles were review articles, recommendations, case reports or series, or population-based studies (cross-sectional, cohort, case-control, or interventional), and full-text if available.
Results A total of 124 articles were identified through the search strategy. The two reviewers screened titles and abstracts of all articles. Most articles were excluded because of ineligible to the criteria. Ultimately, 18 articles were included in the final evaluation. MM patients might have higher risk to become severe COVID-19 if they got infected due to their immunocompromised condition. Due to the pandemic, precise treatment priorities should be made by considering its benefit and the risk of MM progression. For the young, especially healthy patients, the most effective therapy should be offered and tailored to the patient’s goal. Several MM societies have published the recommendation regarding the special stage of MM.
Conclusion Myeloma societies in the world have released recommendations related to the management of myeloma patients. However, there is scarce of evidence to do the recommendation.
The Determination of Thiourea Dioxide Residue in Pasta Products by LVFX-AuNPs Fluorescence Resonance Energy Transfer Spectrometry
Authors: Xi Huiping , Fang Xiuwei 
Published: September 2020

Abstract
Fluorescence resonance energy transfer occurs between levofloxacin (LVFX) and gold nanoparticles (AuNPs), which leads to fluorescence quenching of levofloxacin. Due to the strong Au-S bond formed between thiourea dioxide and gold nanoparticles, levofloxacin is released from the surface of gold nanoparticles and fluorescence of the system is recovered. Based on this, a fluorescence spectrometry method for determination of thiourea dioxide was established. This method was used to determine the content of thiourea dioxide in pasta products with RSD less than 3.5% and recovery rate of 93.3~103.3%.

Published: September 2020

Abstract
Room temperature ferromagnetism with large saturation magnetism was first observed in layered TiO2 (LT). The LT is in rich of oxygen vacancy and free of magnetic transition metal elements. The temperature dependence of magnetism indicates that carrier mobility and carrier number of LT are larger than that of anatase TiO2 (AT) and amorphous TiO2 (AMT). The room temperature ferromagnetism is an intrinsic property of LT since there are no magnetic transition metal elements in LT. LT is a good platform to study two-dimensional (2D) magnetism.

Published: September 2020

Abstract
Concrete is one of the most widely-used materials in construction. However, there often exist some inevitable cracks due to its brittleness. The durability and service life of the concrete structure will therefore be reduced largely. Self-healing concrete is one of the feasible and effective techniques which can respond to cracks in an astute way, and easing or even repair the cracks completely. Overviews are provided here with concrete self-healing mechanism and self-healing trigger mechanism. Based on the related principles of self-healing technology, the paper analyzes the existing self-healing technology from different aspects and forecasts the future development direction. Concrete self-healing mechanisms are classified mainly into three types as physical, chemical and biological ones. Self-healing trigger mechanisms are summed up with two aspects as physical trigger and chemical trigger respective. In recent years, concrete self-healing mainly develops to chemical, biological and composite repair mechanisms, and the trigger mechanism develops to chemical trigger such as ion trigger. Based on the recent development of technology some viewpoints about present technology improvements and major future developments are pointed out for reference.

Abstract
The paper tested conventional and Srtategic Highway Research Program(SHRP) index performance of TPE and SBS modified asphalt. The test results show that TPE modified asphalt can effectively improve the high temperature performance, water stability and low temperature performance of asphalt mixture. Although the performance of TPE modified asphalt is inferior to SBS modified asphalt, the three major indexes all meet the specification requirements. The overall road performance of TPE modified asphalt mixture meets the technical requirements of modified asphalt, and even from the rut test and SPT test results, the high-temperature anti rut performance is higher than SBS asphalt mixture.

Authors: Ren Zhong 
Published: September 2020

Abstract
In the study, the numerical simulations of gas-assisted extrusion molding (GAEM) of double-lumen micro-catheter (DLMC) with asymmetric structure were performed via the finite element software package Polyflow. At the same time, the numerical results of traditional extrusion were also obtained. The numerical extrusion profile, deformation, and the die swell ratios of DLMC based on the traditional and GAEM were all gotten, and compared with each other. In addition, to analyze the effect of gas-assisted on the elimination of the extrusion problems, the physical field distributions of melt for both extrusions were also compared and analyzed. Numerical results show that the obvious die swell and large extrusion deformation of DLMC generated by the traditional method were all eliminated by using the GAEM.

Published: September 2020

Abstract
Stainless steel will become one of the main substrate materials of flexible large-scale display. The biggest problem of stainless steel as flexible display substrate is that the surface roughness is too large, so it is necessary to be ultra-precision machining on its surface, such as the chemical mechanical polishing (CMP). How to select the most representative measurement points in measuring surface roughness after CMP is the first problem to be solved. Based on the idea of orthogonal design, taking a roll of ultra-thin flexible stainless steel substrate as an example, the method and algorithm of selecting 12 measuring points on a 600mm×100mm rectangular area are obtained. This method avoids the blindness in random selection of measurement points, and reduces the workload of selecting measurement points. It can provide a reference for the selection of measurement points on the large-scale surface after ultra-precision machining.

Abstract
In order to improve the mechanical properties and spinning performance of luminescent nylon fibers, different proportions of graphene were used for melt spinning, and the best spinning process of graphene-doped luminescent nylon 150D/36F composite fiber was found. The effects of doped graphene on the mechanical properties, molecular structure and luminescent properties of luminescent nylon fibers were analyzed by means of electron microscope scanning, infrared spectroscopy, test instrument of long afterglow properties and monofilament strength tester. The experimental results show that the mechanical properties of the fiber are improved after graphene is doped into the luminescent nylon. Considering the luminescent properties and mechanical properties of the fiber, the comprehensive properties of the fiber are the best when the amount of graphene is 0.5‰.

Authors: Zhang Baohong , Hu Bin , Zhang Zhimin , Zhao Xi 
Published: September 2020

Abstract
The effect of friction coefficient, reduction of thickness, forming speed, roller diameter on the coefficient of forward slip at the rim of the roller during cup roll forming was studied by numerical simulation. The results show that during roll pre-forming, the friction coefficient and forming speed have little effect on the coefficient of forward slip, and the reduction of thickness and the diameter of the roller have a greater influence on the coefficient of forward slip; as the reduction of thickness increases, the coefficient of forward slip increases; as the roller diameter increases, the coefficient of forward slip increases first and then decreases. The coefficient of forward slip during the roll pre-forming of cup is much larger than that of roll forging. During roll shaping, the process parameters have little effect on the coefficient of forward slip and its value is close to zero, that is, the axial length of the roll shaped part is almost equal to the arc length of the roller rim. The accuracy of numerical simulation is verified by experiments, and the error between the numerical simulation and experiment is less than 1%.

Abstract
The aim of the experiment was to study the immunohistochemical reaction the periodontal tissues regenerated by nano biphasic calcium phosphate bioceramics (NBCP). Two lateral third incisors were randomly selected and operated as experimental group in two beagle dogs. As control the contralateral third incisors of the same jaw were done nothing. In experimental group, alveolar bone defects were made surgically at the labial aspects of the teeth. After root conditioning, the defects were filled with NBCP. 16 weeks after operation, the dogs were killed. The immunohistochemistry examination was used to observe the newly formed periodontium in the experimental group and the normal periodontium in the control group. The positive expressions of osteocalcin (OCN) in newly formed periodontium were the same to that in normal periodontal tissues.

Abstract
Interfacial interaction between flaked graphene and resins was the key element of effecting whether graphene as nanofillers could improve some of the properties of pure resin. Based on really materials and applied manufacturing process, a new kind of an effective modulus predictive method for resins modified with graphene which could compute and analyze modulus of any content ratio of graphene in the resin with only one content ratio was built in order to provide theoretical foundations for design and property of resins modified with graphene. According to practically different materials system and corresponding manufacturing processes, few experiments which only needed elastic modulus of resins modified with one random content-ratio graphene were made to predict effective elastic modulus of any other content ratio of graphene modifying resins under the same manufacturing processes by obtaining experimental constants based on numerical progressive iterative approximation method and compute the above experimental constants as basic materials parameters so as to build the whole analysis model in the next step. An excellent agreement was found between data obtained from this study and the experiment.

Published: September 2020

Abstract
Biosynthesis of silver nanoparticles (AgNPs) using HoneySuchle Flowers Extract as reducing and stabilizing agent has been discussed in this paper, and AgNPs have been characterized by UV-Vis spectroscopy, DLS analysis, TEM and EDS analysis. The surface plasmon resonance (SPR) peak of AgNPs was observed at around 429 nm, and the average particles size of AgNPs was around 50 nm. The biosynthesis temperature had great impact on the particle size distributions of AgNPs and thereby affected the catalytic characteristics of AgNPs for the reductive degradation of Direct Violet 1 by NaBH4. The results showed that increasing of AgNPs particle size was upon the increasing of reaction temperature, which was adverse to catalytic reactivity of AgNPs.
