AbstractAn increasing number of chronic renal failure patients are experiencing hip joint disorders. This study aimed to analyze the outcomes of hip arthroplasty in chronic renal failure patients undergoing dialysis. Of 2364 hips that underwent hip arthroplasty during 2003–2017, 37 were retrospectively examined. Radiological and clinical outcomes of hip arthroplasty, and development of local and general complications during follow-up and their associations with dialysis duration were analyzed. The mean patient age, follow-up duration, and bone mineral density T-score were 60.6 years, 36.6 months, and − 2.62, respectively. Osteoporosis was noted in 20 cases. Most patients who underwent total hip arthroplasty with a cementless acetabular cup implant exhibited excellent radiological outcomes. There were no changes in femoral stem alignment, subsidence, osteolysis, and loosening. Thirty-three patients had an excellent or good Harris hip score. Complications developed in 18 patients within 1 year postoperatively. General complications developed in 12 patients at > 1 year postoperatively; no patient experienced local complications. In conclusion, hip arthroplasty for chronic renal failure patients on dialysis yielded excellent radiological and satisfactory clinical outcomes but may be associated with postoperative complications. Careful preoperative treatment planning and overall postoperative management are required to reduce the complication risk.

Published: February 2023

AbstractFour pathogenic bacterial species of the genus ‘Candidatus Liberibacter’, transmitted by psyllid vectors, have been associated with serious diseases affecting economically important crops of Rutaceae, Apiaceae and Solanaceae families. The most severe disease of citrus plants, huanglongbing (HLB), is associated with ‘Ca. Liberibacter asiaticus’ (CaLas), ‘Ca. Liberibacter americanus’ (CaLam) and ‘Ca. Liberibacter africanus’ (CaLaf), while ‘Ca. Liberibacter solanacearum’ (CaLsol) is associated with zebra chip disease in potatoes and vegetative disorders in apiaceous plants. Since these bacteria remain non-culturable and their symptoms are non-specific, their detection and identification are done by molecular methods, mainly based on PCR protocols. In this study, a new quantitative real-time PCR protocol based on TaqMan probe, which can also be performed in a conventional PCR version, has been developed to detect the four known phytopathogenic species of the genus Liberibacter. The new protocol has been validated according to European Plant Protection Organization (EPPO) guidelines and is able to detect CaLas, CaLam, CaLaf and CaLsol in both plants and vectors, not only using purified DNA but also using crude extracts of potato and citrus or psyllids. A comparative analysis with other previously described qPCR protocols revealed that this new one developed in this study is more specific and equally or more sensitive. Thus, other genus-specific qPCR protocols have important drawbacks regarding the lack of specificity, while with the new protocol there was no cross-reactions in 250 samples from 24 different plant and insect species from eight different geographical origins. Therefore, it can be used as a rapid and time-saving screening test, as it allows simultaneous detection of all plant pathogenic species of ‘Ca. Liberibacter’ in a one-step assay.

AbstractAlGaN-based ultraviolet (UV) light-emitting diodes (LEDs) are expected to have various applications, including sensing and printing, and light with ultraviolet-C (UVC) wavelengths has a virus inactivation effect. The metalorganic vapor phase epitaxy (MOVPE) method has been used to fabricate LED devices with film control and impurity doping. However, to achieve high luminous efficiency, highly crystalline aluminum nitride (AlN) must be grown in the underlying layer. Although high temperatures are required to grow high-quality AlN for strong migration at the surface, there is a trade-off in the high temperature promoting parasitic reactions. These parasitic reactions are more dominant at a high V/III ratio with more raw material in the case of using the conventional MOVPE. Here, we used jet stream gas flow MOVPE to investigate the effect of V/III ratio dependencies in optimizing AlN growth and without affecting parasitic reaction conditions. As a result, trends of typical AlN crystal growth at V/III-ratio dependencies were obtained. AlN is more stable at a higher V/III ratio of 1000, exhibiting a double atomic step surface, and the crystal orientation is further improved at 1700 °C compared to that at a lower V/III ratio.

AbstractSpherical nanocarriers can lead to a bright future to lessen problems of virus infected people. Spherical polyethylene glycol (PEG) and spherical silica (SiO2) are novel attractive nanocarriers as drug delivery agents, especially they are recently noticed to be reliable for antiviral drugs like anti-HIV, anti-covid-19, etc. Lamivudine (3TC) is used as a first line drug for antiviral therapy and the atomic view of 3TC-PEG/SiO2 complexes enable scientist to help improve treatment of patients with viral diseases. This study investigates the interactions of 3TC with Spherical PEG/SiO2, using molecular dynamics simulations. The mechanism of adsorption, the stability of systems and the drug concentration effect are evaluated by analyzing the root mean square deviation, the solvent accessible surface area, the radius of gyration, the number of hydrogen bonds, the radial distribution function, and Van der Waals energy. Analyzed data show that the compression of 3TC is less on PEG and so the stability is higher than SiO2; the position and intensity of the RDF peaks approve this stronger binding of 3TC to PEG as well. Our studies show that PEG and also SiO2 are suitable for loading high drug concentrations and maintaining their stability; therefore, spherical PEG/SiO2 can reduce drug dosage efficiently.

Published: February 2023

AbstractThe first genome assemblies of Gnomoniopsis castaneae (syn. G. smithogilvyi), the causal agent of chestnut brown rot of kernels, shoot blight and cankers, are provided here. Specifically, the complete genome of the Italian ex-type MUT401 isolate was compared to the draft genome of a second Italian isolate (GN01) and to the ICMP 14040 isolate from New Zealand. The three genome sequences were obtained through a hybrid assembly using both short Illumina reads and long Nanopore reads, their coding sequences were annotated and compared with each other and with other Diaporthales. The information offered by the genome assembly of the three isolates represents the base of data for further application related to -omics strategies of the fungus and to develop markers for population studies at a local and global scale.

Published: February 2023

AbstractTo determine whether photobiomodulation (PBM) therapy can retard ocular axial length (AL) in children with myopia. A randomized controlled clinical trial was conducted on two consecutive cohorts of 50 eligible children aged 8–12 years with ≤ − 0.75 Diopter (D) of spherical equivalent refraction (SER). Participants were randomly assigned to the intervention group (n = 25) and treated with PBM therapy or the control group (n = 25) and treated with single vision spectacles only. At the 12-month follow-up, the changes in AL and cycloplegic SER from baseline were both compared between the two groups. In addition, the subfoveal choroidal thickness (SFChT), anterior chamber depth (ACD), and central corneal refractive power (CCP) were analysed at the 3-, 6-, 9-, and 12-month follow-ups, respectively. Among the 50 children, 78% were included at the final follow-up, with a mean age of 9.7 ± 1.5 years and a mean SER of − 2.56 ± 1.70. The mean difference in AL growth between the two groups at 12 months was 0.50 mm (PBM vs. Control, − 0.02 mm ± 0.11 vs. 0.48 mm ± 0.16, P < 0.001), and the mean difference in cycloplegic SER at 12 months was + 1.25 D (PBM vs. Control, + 0.28 D ± 0.26 vs. − 0.97 D ± 0.25, P < 0.001). There were no significant differences in any of the other parameters (including SFChT, ACD, and CCP) between the two groups at any time point. PBM therapy is an effective intervention for slightly decreasing the AL to control myopia in children.Trial registration: Chinese Clinical Trial Registration Number: ChiCTR2100043619.

AbstractAs the Zhurong rover landed on the surface of Mars in 2021, it began a months-long collection of Mars data. Equipped with highly sensitive sensors, Zhurong is capable of being a meteorological station at the surface of Mars. The Mars Climate Station, one of the onboard sensors with high sensitivity, helps the Tianwen-1 lander to collect meteorological data at the Martian surface, via which the air temperature, atmospheric pressure, wind speed and direction are measured. In this paper, we present results of surface pressure, air temperature and wind data from the Mars Climate Station at Zhurong’s landing site. The data is collected in 176 solar days out of the entire rover’s mission time, 325 solar days. We use a trigonometric function to fit the relationship between the solar longitude (Ls) and the pressure, after which we compare the results with those of Viking I. Our analysis of the temperature shows that seasonal evolution is similar to the patterns concluded in previous Mars missions at different landing sites. We discover that wind speed appears the maximum in early summer near Zhurong’s landing site, and analyze the occurrence of dust storms by combining the data of wind and temperature. Our results provide some evidence of the seasonal changes in meteorological pattern at Tianwen-1’s landing site, south of Utopia Planitia. With the mission ongoing further, more results are expected in the future.

Pour favoriser la performance, certains entraîneurs ont souvent recours au feedback (FB) verbal, à l’Observation d’un Modèle (OM) ou à l’imagerie motrice (IM) consistant à simuler mentalement réaliser une action. Cette étude avait pour but de tester les effets d’une combinaison de FB, d’OM et d’IM sur la performance du 25 m départ plongé en natation chez des non-experts. Cent-six étudiants volontaires (Mage = 19,3), aléatoirement divisés en 3 groupes : FB, FB+OM et FB+OM+IM, ont réalisé 3 phases réparties sur 6 séances. Séance 1 (pré-test), ils ont réalisé 5 × 25 m départs plongés (filmés et chronométrés). Les 4 séances suivantes (8 × 25 m départ plongé), ils recevaient un FB verbal (chaque 2 essais), ceux du groupe FB+OM bénéficiaient en plus de la vidéo et ceux du groupe FB+OM+IM s’imaginaient réaliser un plongeon après la vidéo. Séance 6 (post-test) : similaire à la séance 1. Les résultats montrent que tous les participants ont amélioré leur vitesse de coulée, mais seul le groupe FB+OM+IM a amélioré la distance de coulée et le temps sur 25 m. L’intérêt de combiner les modalités de pratique, pour améliorer le 25 m départ plongé, est discuté au regard de la littérature.
Prävention des Pankreaskarzinoms
Authors: Scherübl Hans 
Published: February 2023

ZusammenfassungDas Pankreaskarzinom nimmt in Deutschland stetig an Häufigkeit zu und stellt aktuell die dritthäufigste tumorbedingte Todesursache dar. Voraussichtlich rückt es bis 2030 auf den 2. Platz und bis 2050 auf den 1. Platz der krebsbedingten Todesfälle vor. Das Pankreasadenokarzinom wird in der überwiegenden Mehrzahl der Fälle spät diagnostiziert und die 5-Jahre-Überlebensrate liegt nach wie vor bei nur 10 %. Zu den beeinflussbaren Risikofaktoren zählen das Tabakrauchen, ein übermäßiges Körpergewicht, der Alkoholkonsum, der Typ-2-Diabetes und das metabolische Syndrom. Der Rauchstopp und die gewollte Gewichtsabnahme (bei Adipositas) können das Pankreaskrebsrisiko um etwa 50 % reduzieren. Zudem ist die Früherkennung des sporadischen Pankreaskarzinoms im Stadium IA – nun mit einem 5-Jahre-Überleben von 80 % – bei Menschen über 50 mit neu diagnostiziertem Diabetes eine realistische Perspektive geworden. Aktuelle Entwicklungen hierzu werden kurz beschrieben.

Published: February 2023

AbstractObjectives Surgical repair of Type A aortic dissection (TAAD) requires exclusion of the primary entry tear and reestablishment of flow into the distal true lumen. Provided that the majority of tears occur within the ascending aorta (AA), replacing only that segment seems a safe option; however, this strategy leaves the root susceptible to dilatation and need for reintervention. We aimed to review the outcomes of the two strategies: aortic root replacement (ARR) and isolated ascending aortic replacement.Methods Retrospective analysis of prospectively collected data for all consecutive patients who underwent repair of acute TAAD at our institution from 2015 to 2020 was conducted. Patients were divided into two groups: (1) ARR and (2) isolated AA replacement as index operation for TAAD repair. Primary outcomes were mortality and need for reintervention during the follow-up.Results A total of 194 patients were included in the study; 68 (35%) in the ARR group and 126 (65%) in the AA group. There were no significant differences in postoperative complications or in-hospital mortality (23%; p = 0.51) between groups. Seven patients (4.7%) died during follow-up and eight patients underwent aortic reinterventions, including proximal aortic segments (two patients) and distal procedures (six patients).Conclusion Both aortic root and AA replacement are acceptable and safe techniques. The growth of an untouched root is slow, and reintervention in this aortic segment is infrequent compared with distal aortic segments, hence preserving the root could be an option for older patients provided that there is no primary tear within the root.

AbstractAcute aortic dissection is one of the most lethal diseases, affecting the lining of the aortic wall. We describe a case of Stanford Type A aortic dissection in a patient with underlying primary antiphospholipid syndrome (APS) complicated by coronavirus disease 2019 (COVID-19). APS is characterized by recurrent venous and/or arterial thrombosis, thrombocytopenia, and rarely vascular aneurysms. The hypercoagulable milieu attributable to APS and the prothrombotic state from COVID-19 posed a challenge in achieving optimal postoperative anticoagulation in our patient.

Background HIV self-testing (HIVST) could promote HIV tests; however, knowledge about the mechanisms by which providing HIVST kits impacts the uptake of HIV testing is limited. This study aimed to examine how self-efficacy mediates the association between providing HIVST kits and HIV testing frequency. Methods In this randomised controlled trial, HIV-negative men who have sex with men (MSM) were recruited in China and randomly assigned 1:1 into intervention and control groups. MSM in the control group could access site-based HIV testing services (SBHT). MSM in the intervention group could access SBHTs plus free HIVST kits. HIV testing self-efficacy, number of SBHTs, number of HIVSTs, and the total number of HIV tests were assessed every 3 months for 1 year. Results Data from 216 MSM (intervention group: 110; control group: 106) were included in analysis. Results from Pearson’s correlations and point-biserial correlations showed that participants with higher self-efficacy scores underwent a higher number of HIV tests (r = 0.241, P < 0.001), more HIVSTs (r = 0.162, P < 0.001), and more SBHTs (r = 0.138, P < 0.001). Bootstrap tests using PROCESS indicated self-efficacy partially mediated the effect of providing HIVST on the number of HIVSTs (indirect effect: 0.018, 95% bias-corrected confidence interval [BC CI]: 0.003–0.035; direct effect: 0.440, 95% BC CI: 0.366–0.513) and on total HIV tests (indirect effect 0.053 (0.030–0.787); direct effect 0.452 (0.365–0.539)), and completely mediated the effect of providing HIVST on the number of SBHTs (indirect effect 0.035 (0.019–0.056); direct effect 0.012 (−0.059 to 0.083)). Conclusions Our findings indicated self-efficacy mediated the effect of HIVST provision on HIV testing frequency, suggesting improving self-efficacy might be an effective way to promote HIV testing among Chinese MSM.

Here, we combine international air travel passenger data with a standard epidemiological model of the initial 3 mo of the COVID-19 pandemic (January through March 2020; toward the end of which the entire world locked down). Using the information available during this initial phase of the pandemic, our model accurately describes the main features of the actual global development of the pandemic demonstrated by the high degree of coherence between the model and global data. The validated model allows for an exploration of alternative policy efficacies (reducing air travel and/or introducing different degrees of compulsory immigration quarantine upon arrival to a country) in delaying the global spread of SARS-CoV-2 and thus is suggestive of similar efficacy in anticipating the spread of future global disease outbreaks. We show that a lesson from the recent pandemic is that reducing air travel globally is more effective in reducing the global spread than adopting immigration quarantine. Reducing air travel out of a source country has the most important effect regarding the spreading of the disease to the rest of the world. Based upon our results, we propose a digital twin as a further developed tool to inform future pandemic decision-making to inform measures intended to control the spread of disease agents of potential future pandemics. We discuss the design criteria for such a digital twin model as well as the feasibility of obtaining access to the necessary online data on international air travel.
Extramural English for early language learning

Published: February 2023

Abstract
Due to the online global presence of English, many EFL learners encounter English outside the classroom from an early age. This study examined teachers’ perceptions of the language learning affordances, challenges, and benefits in the early English classroom (ages 7–11) of English learnt outside school (extramural English (EE), Sundqvist & Sylvén, 2016). A mixed-methods approach, including a survey, interviews, and data from Facebook interest groups on teaching English, was used to gauge teacher perceptions. Results showed that generally teachers had positive attitudes towards the learning potentials of EE (especially related to fostering vocabulary learning) and for creating motivation for learning English. Teachers found less benefits of playing digital games than from watching YouTube videos. Teachers also reported demotivation in students stemming from being bored in class or from feeling behind compared to others, i.e., personal expectations of English skills were high. The study points to a need for focus in teacher education on the benefits of extramural activities for their students’ learning (especially gaming). This means fostering awareness in prospective teachers of the importance of incidental learning processes as these are key in the global English context. Moreover, sharing ideas for integrating EE into teaching practices is needed.
