BACKGROUND Early diagnosis is key to prevent bowel damage in inflammatory bowel disease(IBD).Risk factor analyses linked with delayed diagnosis in European IBD patients are scarce and no data in German IBD patients *** To identify risk factors leading to prolonged diagnostic time in a German IBD *** Between 2012 and 2022,430 IBD patients from four Berlin hospitals were enrolled in a prospective study and asked to complete a 16-item questionnaire to determine features of the path leading to IBD *** diagnostic time was defined as the time from symptom onset to consulting a physician(patient waiting time)and from first consultation to IBD diagnosis(physician diagnostic time).Univariate and multivariate analyses were performed to identify risk factors for each time *** The total diagnostic time was significantly longer in Crohn’s disease(CD)compared to ulcerative colitis(UC)patients(12.0 vs 4.0 mo;P<0.001),mainly due to increased physician diagnostic time(5.5 vs 1.0 mo;P<0.001).In a multivariate analysis,the predominant symptoms diarrhea(P=0.012)and skin lesions(P=0.028)as well as performed gastroscopy(P=0.042)were associated with longer physician diagnostic time in CD *** UC,fever was correlated(P=0.020)with shorter physician diagnostic time,while fatigue(P=0.011)and positive family history(P=0.046)were correlated with longer physician diagnostic *** We demonstrated that CD patients compared to UC are at risk of long diagnostic *** efforts should focus on shortening the diagnostic delay for a better outcome in these patients.

Adverse events related to physical restraint use in intensive care units: A review of the literature

引用

Journal of Intensive Medicine 2024年第3期4卷 318-325页

作者： Sebastian Berger Pascale Grzonka Simon A.Amacher Sabina Hunziker anja I.Frei Raoul Sutter Clinic for Intensive Care Department of Acute MedicineUniversity Hospital BaselBaselSwitzerland Medical Communication and Psychosomatic Medicine University Hospital BaselBaselSwitzerland Medical faculty University of BaselBaselSwitzerland Department of Clinical Research University of BaselBaselSwitzerland

Physical restraints are widely used and accepted as protective measures during treatment in intensive care unit (ICU). This review of the literature summarizes the adverse events and outcomes associated with physical restraint use, and the risk factors associated with their use during treatment in the ICU. The PubMed, Scopus, and Google Scholar databases were screened using predefined search terms to identify studies pertaining to adverse events and/or outcomes associated with physical restraint use, and the factors associated with their use in adult patients admitted to the ICU. A total of 24 articles (including 6126 patients) that were published between 2006 and 2022 were identified. The described adverse events associated with physical restraint use included skin injuries, subsequent delirium, neurofunctional impairment, and a higher rate of post-traumatic stress disorder. Subsequent delirium was the most frequent adverse event to be reported. No alternative measures to physical restraints were discussed, and only one study reported a standardized protocol for their use. Although physical restraint use has been reported to be associated with adverse events (including neurofunctional impairment) in the literature, the available evidence is limited. Although causality cannot be confirmed, a definite association appears to exist. Our findings suggest that it is essential to improve awareness regarding their adverse impact and optimize approaches for their detection, management, and prevention using protocols or checklists.

诺丽果汁是一种发源于热带地区并在全球推广的健康饮料。研究证实，诺丽果具有一定的保健作用，通过回顾性研究发现，诺丽果汁可减少吸烟引起的DNA损伤、降低血脂和同型半胱氨酸水平并减轻全身炎症反应。临床研究还表明，诺丽果汁可以改善关节健康、增强身体耐力、增加免疫活性、抑制蛋白质糖化、有助于控制体质量、保护女性骨骼健康、维持正常血压并改善牙龈健康。此外，诺丽果汁还具有较强的抗氧化活性，可与免疫系统和炎症反应相互作用，是诺丽果汁发挥保健作用的关键所在。然而，回顾性研究也有局限性，诺丽果汁产地单一，均为波利尼西亚大溪地区域，地理因素和加工方法的不同会导致诺丽果汁的化学成分和营养成分存在差异。因此，其他来源的诺丽果汁是否具有相同的毒理学和药理学特征还有待进一步研究。

Application of Electron Beam Surface Technologies in the Automotive Industry

材料热处理学报 2004年第5期25卷 573-578页

作者： Rolf Zenker anja Buchwalder TU Bergakademie Freiberg /Zenker Consult Mittweida GermanyTU Bergakademie Freiberg Germany

Progress in the beam deflection technique opens up new possibilities for the application of electron beam (EB) surface and welding technologies in the automotive industry. This development is based on three-dimensional high-speed beam deflection and fully automatic online process control. So, in the EB surface treatment three-dimensional energy transfer fields can be realised which take into account the contour of a component, the conditions of heat conduction and the load conditions. High flexibility, precision and reproducibility are typical characteristics. High productivity is achieved by the simultaneous interaction of the EB in several processing areas or by carrying out several processes simultaneously. EB surface treatment is becoming more and more attractive and important especially in the automotive industry, and also in comparison to laser technologies. This paper deals with different EB surface technologies, for example hardening, remelting, surface alloying, dispersing or cladding of different materials such as steel, cast iron and different alloys of Al, Mg and Ti. Examples of applications in the automotive industry, especially engine components, will be discussed.

Insights into manganese transport: A matter of phosphorylation

作者： anja Schneider Plant Science Faculty of BiologyLudwig-Maximilians-Universität MünchenMunichGermany

Manganese(Mn)is an essential element required for the growth of all known living *** plants acquire Mn from the rhizosphere,and its translocation into,and distribution within,the plant involves a multitude of transporters(Alejandro et al.,2020).In the aerial part of the green plant,the most prominent reaction that depends on Mn is the water-splitting reaction of photosystem II,which employs a tetra-Mn cluster located in the thylakoid lumen of ***,no less important reactions take place in mitochondria,where a Mn superoxide dismutase acts as a scavenger of reactive oxygen species,and in the Golgi apparatus,where Mn-dependent glycosyltransferases are involved in cell wall biosynthesis.

作者： P.W.west Forest Research Centre Southern Cross UniversityLismoreNSW 2480Australia

Inventory data were available from 96 plots of even-aged,monoculture,tall-open forests of Eucalyptus pilularis Smith,aged 2-63 years,growing in sub-tropical regions along the east coast of Australia.A model was developed relating the maximum possible stem basal area growth rate of individual trees to their stem basal *** any tree size,this maximum increased as site productivity ***,the size at which this maximum occurred decreased as productivity *** research has shown that,at any stand age,trees of a particular stem basal area are taller on more productive sites than on less productive *** trees incur greater respiratory costs to ensure maintenance of the photo synthetic capacity of their canopies;this reduces their growth *** was concluded that trees with larger basal areas will have the maximum possible growth rate on a less productive site,whilst trees with smaller basal areas will have the maximum possible on a more productive *** model developed may constitute the first stage of a complete individual tree growth model system to predict wood yields from these forests.
