German guidelines on the diagnosis and treatment of neurosyphilis
No full textIntroduction In view of the importance of neurosyphilis and the difficulties encountered in diagnosing it, the S1 guideline “Neurosyphilis” has been published by the German Society for Neurology (DGN) in accordance with the stipulations of the Association of the Scientific Medical Societies in Germany (AWMF). The present article is an abridged translation of that German guideline. Main recommendations (a) Neurosyphilis can manifest as early neurosyphilis (meningitis, meningovascular neurosyphilis or syphilitic gummas) or late neurosyphilis (tabes dorsalis, general paresis). (b) The following diagnostic criteria help to establish the presence of probable neurosyphilis (always point iv, accompanied by any two of points i to iii): (i) subacute or chronic neuro-psychiatric symptoms; (ii) increased cerebrospinal fluid (CSF) cell count or signs of blood–CSF barrier disruption; (iii) positive effect of anti-neurosyphilis antibiotic therapy on clinical course and CSF findings; (iv) positive TPHA/TPPA or FTA test in serum. (c) The diagnosis of neurosyphilis is confirmed by the subsequent detection of intrathecal production of antibodies against Treponema pallidum . (d) In neurosyphilis, treatment with intravenous penicillin or ceftriaxone for 14 days is recommended. (e) The following parameters can be used to assess a therapeutic effect: clinical findings, serum VDRL, and CSF cell count. Conclusion The German guideline on the diagnosis and treatment of neurosyphilis is a practical tool to support clinicians in diagnosing and treating patients with neurosyphilis. This article is an abridged translation of this guideline (Klein MW, J.; Angstwurm, K.; Esser, S.; Hahn, K.; Matschke, M.; Scheithauer, S.; Schoefer, H.; Sturzenegger, M.; Wildemann, B.

Studentische Ausbildung in der Notfallmedizin. Überblick, Konzepte und Perspektiven
No full textThe new revised regulations of medical licensure in Germany postulate wider implementation of emergency medical care in the undergraduate medical school curriculum. Teaching in this subject should be organized in an interdisciplinary manner and also allow small group teaching. This overview introduces different concepts of emergency medical care in undergraduate medical education and gives a summary of common teaching and assessment methods in Germany. With the public having the right to expect that every physician possesses basic knowl-edge and the necessary skills of emergency medical care, the communication of these competencies is based on a high level of education quality. Furthermore, potential areas for improvement as well as perspectives with the standardization of learning objectives are discussed
Activation of TGF-β-induced non-Smad signaling pathways during Th17 differentiation
No full textAlthough transforming growth factor-β (TGF-β) has been shown to positively regulate the development of murine T helper type 17 (Th17) cells, which of the intracellular signaling pathways are involved is controversial. We examined Smad-dependent and -independent signaling molecules downstream of the TGF-β receptor (TGFβR) involved in Th17 differentiation of naive murine CD4(+)CD62L(+) T cells. During Th17 differentiation of wild-type T cells, Smad2/3 was phosphorylated, indicating activation of the canonical Smad pathway. T cells lacking TGFβRII did not differentiate into Th17, whereas T cells treated with a TGFβRI kinase inhibitor (SB-431542) or overexpression of inhibitory Smad7 retained a low amount of Th17 polarization despite absent Smad2/3 phosphorylation. Using protein antibody arrays we found an increase of expression and phosphorylation of the following Smad-independent signaling molecules in Th17-polarized wild-type T cells: AKT1(Tyr474), AKT2 (Ser474), ERK1-p44/42 MAPK(Tyr204), mTOR(Thr2446), p38 MAPK(Thr180), Rac1/cdc42(Ser71), SAPK/JNK(Tyr185) and SP1(Thr739). Pharmacological inhibition of AKT/mammalian target of rapamycin (mTOR) signaling with rapamycin or LY294002 decreased Th17 differentiation of wild-type T cells, and completely abolished interleukin-17 production in T cells with overexpression of Smad7. Rapamycin and LY294002 also decreased induced regulatory T cell differentiation, but only had minor additive effects to Smad7 overexpression. Finally, inhibitors of mitogen-activated protein kinase (MAPK) blocked in vitro polarization of Th17 cells. Our data show that Smad-dependent and -independent intracellular pathways contribute to murine Th17 differentiation

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

Simulation of thermal plant optimization and hydraulic aspects of thermal distribution loops for large campuses
No full textFollowing an introduction, the author describes Texas A&M University and its utilities system. After that, the author presents how to construct simulation models for chilled water and heating hot water distribution systems. The simulation model was used in a $2.3 million Ross Street chilled water pipe replacement project at Texas A&M University. A second project conducted at the University of Texas at San Antonio was used as an example to demonstrate how to identify and design an optimal distribution system by using a simulation model. The author found that the minor losses of these closed loop thermal distribution systems are significantly higher than potable water distribution systems. In the second part of the report, the author presents the latest development of software called the Plant Optimization Program, which can simulate cogeneration plant operation, estimate its operation cost and provide optimized operation suggestions. The author also developed detailed simulation models for a gas turbine and heat recovery steam generator and identified significant potential savings. Finally, the author also used a steam turbine as an example to present a multi-regression method on constructing simulation models by using basic statistics and optimization algorithms. This report presents a survey of the author??s working experience at the Energy Systems Laboratory (ESL) at Texas A&M University during the period of January 2002 through March 2004. The purpose of the above work was to allow the author to become familiar with the practice of engineering. The result is that the author knows how to complete a project from start to finish and understands how both technical and nontechnical aspects of a project need to be considered in order to ensure a quality deliverable and bring a project to successful completion. This report concludes that the objectives of the internship were successfully accomplished and that the requirements for the degree of Degree of Engineering have been satisfied
Qualitätsmanagement der klinisch-praktischen Ausbildung im Praktischen Jahr des Medizinstudiums – Vorschlag eines Kriterienkatalogs der Gesellschaft für Medizinische Ausbildung
No full text[english] Objectives: Amended in 2013, the current version of the German Medical Licensure Regulation contains structural specifications that are also required of non-university institutions involved in Practical Year clinical training. The criteria are worded in relatively general terms. Furthermore, not all of the structural specifications can be readily applied to every subject area. In order to ensure commensurability in Practical Year instruction in Germany, not least in light of recently introduced Practical Year mobility, it is necessary to define consistent quality criteria for Practical Year training. The authors therefore propose a catalogue of criteria for the quality management process in Practical Year instruction facilities.Methods: In January 2014, the board of directors of the German Society for Medical Education decided to establish a committee comprised of representatives from various German medical faculties. In a process similar to the Delphi methodology, the group developed criteria for structure, process and outcome quality in Practical Year training in Germany.Results: The criteria developed for structure, process and outcome quality apply to Practical Year training in academic teaching hospitals and university medical centres. Furthermore, modalities for review are proposed. Conclusions: The present catalogue of criteria is intended to contribute to the formation of a basis for the most consistent quality standards possible for Practical Year instruction in Germany
