Abstract
Understanding the molecular structure of the hydration shells and their impact on the hydrogen bond (HB) network of water in aqueous salt solutions is a fundamentally important and technically relevant question. In the present work, such hydration effects were studied for a series of representative salt solutions (NaCl, KCl, CaCl2, MgCl2, and KBr) by soft X-ray emission spectroscopy (XES) and resonant inelastic soft X-ray scattering (RIXS). The oxygen K-edge XES spectra could be described with three components, attributed to initial state HB configurations in pure water, water molecules that have undergone an ultrafast dissociation initiated by the X-ray excitation, and water molecules in contact with salt ions. The behavior of the individual components, as well as the spectral shape of the latter component, has been analyzed in detail. In view of the role of ions in such effects as protein denaturation (i.e., the Hofmeister series), we discuss the ion-specific nature of the hydration shells and find that the results point to a predominant role of anions as compared to cations. Furthermore, we observe a concentration-dependent suppression of ultrafast dissociation in all salt solutions, associated with a significant distortion of intact HB configurations of water molecules facilitating such a dissociation.

Abstract
PURPOSE In hepatic resections, there has been a high quality demand. The aim of this systematic clinical, prospective, unblinded unicenter observational study with two arms in an unselected patient cohort was to investigate whether hemostat device can significantly improve outcome in resective liver surgery, in particular, in high risk patients. METHODS All consecutive patients (mean age, 60.5 [range, 17 - 96] years) who underwent hepatic resection (ntotal = 770) were prospectively documented in a computer-based registry at a university hospital (tertiary center) over a time period of 10 years and retrospectively evaluated specifically with regard to the use (-/+; in daily practice and intraoperative decision-making) of hemostat device (Tissucol(®), n = 59/Tachocomb(®), n = 202/combination, n = 55) indicated (among others) by drainage volume, inflammatory parameters and rate of specific complications (nvalidated = 541 [100 %]). RESULTS Most frequently, (a-)/typical segmental resections were used: n = 192/90 (3-segment resection, only n = 38). 1) For the assignment of patients to the two different groups (-/+ hemostat device), weight loss and type of resection were found as significant factors (trend: ASA, cirrhosis), for the amount of drainage volume, ASA, sex, Karnofsky Performance Scale and also type of resections using independent distributed statistical tests (such as χ(2), U test [Mann/Whitney]; H test [Kruskal-Willis]; correlation coefficient by Spearman) - no impact: smoking, diabetes, BMI, ethanol. 2) Not taking into account these parameters, the use of hemostat device was characterized by an increased drainage volume (negative control < Tissucol = Tachocomb < combination). 3) Using multifactorial analysis of variance, it was found even under correction by the factors with significant impact elucidated in the single test that the application of hemostat device onto the hepatic resection area resulted unexpectedly rather in an increase than a decrease of the drainage volume but 4) under accompanying more pronounced increase of the white blood cell count (leucocytosis). 5) General and specific complications such as postoperative bleeding, biliary fistula and subhepatic abscess were not further lowered in a significant manner using hemostat device. CONCLUSION Adequate surgery in the operative management of hepatic resection area cannot further be improved or optimized using hemostat device. In this context, drainage volume may not be considered a sufficient rather an orienting parameter. However, there is an inflammatory response detectable most likely indicated by a(n un-)specific effusion and increase of white blood cell count, which can be interpreted as a) being characteristic for the problematic group of patients, in whom hemostat device was decided to be useful and was finally used in daily prectice, or b) reactive inflammation to foreign material.

Abstract
Questionnaires were issued to fourth year students and to psychologists in trainee posts who had taken part in the didactic psychological counselling course at the University of Lausanne in Switzerland. This article reviews the various challenges posed by this type of counselling in the university context little accustomed to addressing issues arising in professional practice. This qualitative evaluation shows that the students and trainee psychologists viewed training that combined a university course with practical experience in the future professional .eld as essential. The evaluation also con.rmed that the students believed the objectives and the corresponding teaching tools employed on the course to be relevant. The objectives are also in line with the ‘transdisciplinarity‘ approach proposed by the authors and supported by the CIRET-UNESCO report (1997) extolling the virtues of ‘the four pillars of a new kind of education: learning to know, learning to do, learning to live together with and learning to be‘. Understood in this context, the educational and clinical aims of our counselling course satisfy the new expectations of the university of tomorrow.

Abstract
Clinical departments are constantly faced with complex and novel tasks, which have to be managed with suitable approaches. This article describes selected aspects of project management in this context. In particular, it concentrates on the advantages and limitations of project management methods that have been established in industrial companies when used in a clinical setting. Also it compares the daily reality in clinical departments and industrial companies and highlights possible associations between surgery and project management. Besides aspects such as project planning, role definitions within projects and their specific casting in clinics, the article also demonstrates key success factors for an effective implementation of projects and a general introduction to project management in clinics. The article combines theoretical approaches with practical experience and thought-provoking impulses.

Abstract
Eukaryotic genes are often interrupted by stretches of sequence with no protein coding potential or obvious function. After transcription, these interrupting sequences must be removed to give rise to the mature messenger RNA. This fundamental process is called RNA splicing and is achieved by complicated machinery made of protein and RNA that assembles around the RNA to be edited. Viruses also use RNA splicing to maximize their coding potential and economize on genetic space, and use clever strategies to manipulate the splicing machinery to their advantage. This article gives an overview of the splicing process and provides examples of viral strategies that make use of various components of the splicing system to promote their replicative cycle. Representative virus families have been selected to illustrate the interaction with various regulatory proteins and ribonucleoproteins. The unifying theme is fine regulation through protein-protein and protein-RNA interactions with the spliceosome components and associated factors to promote or prevent spliceosome assembly on given splice sites, in addition to a strong influence from cis-regulatory sequences on viral transcripts. Because there is an intimate coupling of splicing with the processes that direct mRNA biogenesis, a description of how these viruses couple the regulation of splicing with the retention or stability of mRNAs is also included. It seems that a unique balance of suppression and activation of splicing and nuclear export works optimally for each family of viruses.

Abstract
Background: Forensic medicine finds more and more resonance due to requests and queries from clinicians and acts as a mediator between the individual medical disciplines, in particular with regard to legal issues, and as an interface between the fields of medicine, police and judiciary. The aim of this short narrative overview is to make surgeons aware of the forensic aspects of their work, which is usually focused on clinical and curative aspects. Crucial points: Traditionally, the basic work in forensic medicine comprises sudden and unexpected deaths, for which it is important to definitely clarify the mode of death based on the detected cause of death. In addition to violent and unnatural deaths, there are sudden natural deaths, which are natural, but also unsolved. Clinical forensic medicine basically concentrates on the examination of victims of violence, which may comprise various types of bodily harm including sexual crime, child maltreatment and traffic accidents. The investigational results (autopsy findings, injury patterns, results from the investigation of traces) need to be presented and interpreted in public procedures at court by forensic medicine specialists, who act as experts answering questions while retaining a neutral position. Conclusion: Specialists in forensic medicine should not only be consulted for issues related to the inspection of corpses and to issue a death certification. Much rather, they should also be consulted as specialised partners of surgeons and other clinicians, e.g. for the documentation of specific findings and the description of injury patterns in injured persons who are still alive.

Abstract
BACKGROUND Appropriate medication is an important and substantial part in the therapy of tumor-induced pain. OBJECTIVE The objective of this study was to investigate the efficiency of anaesthesiology-based consultant service characterizing the quality of this type of treatment in daily clinical practice of a university hospital, i. e., in the patient profile of a tertiary center (study design: systematic clinical, unicenter observational study reflecting clinical practice and study-based control of therapeutic care quality). METHODS In the course of consulting function with regard to pain care on the single wards a considerable portion of cancer patients are recieving drugs. For most patients such care comprises several consultations and subsequently initiated treatment modifications. The consulting function ends if the patients feel free of pain or report a substantial improvement. From 1/1/2010 to 12/31/2012 detailed information on the drug therapy applied prior to, during and after the consultation was prospectively documented.This data was retrospectively evaluated as "pre-vs.-post" comparison (Chi-squared test, Fisher's exact test and McNemar's test), in particular, focussing on the quality of pain medication using the WHO index as well as pain intensity obtained by means of the visual analogue scale (VAS). RESULTS In total, 375 in-patients were treated. The modified pain medication by the anesthesiological consultant service led to a significant increase (p < 0.001; Wilcoxon's test) in the mean WHO index from 6.37 (SD, 1.83) to 8.43 (SD, 1.47). Furthermore, a reduction of VAS from 5.00 (SD, 2.39) to 2.64 (SD, 1.64) was noted (p < 0.001; Wilcoxon's test). CONCLUSION The consequent application of established guidelines (according to WHO scheme) and the WHO index leads to a qualitative and measurable improvement of drug therapy for cancer-related pain.

Abstract
Background: Surgeons, more than other specialists, are required to combine high medical expertise with management competence. This is due to changing environments, new demands with respect to quality, the ongoing discussion on increased performance in the context of questionable target agreements, an increasing tendency of university hospitals and other departments and clinics to recruit leading personnel in medicine with management competence, but also to the understanding of one's own role and surgeons' distinguished public reputation. Aim: This narrative review describes the changing environments for surgeons in leading positions in hospitals and provides an overview on the practical use of management skills in surgery. In addition, it advises on how to acquire management competence and presents an educational concept appropriate for surgeons in leading positions. Key points: 1. The management of new challenges in the healthcare system - also in clinical surgery - requires management skills, which are indispensable for a surgeon in a leading position. 2. Management skills in surgery comprise aspects such as communication ability, social competence, cooperation and leadership skills, knowledge on business administration aspects and legal certainty. 3. The necessary knowledge can be acquired in courses leading to a certificate (e.g. "MHM® Medical Hospital Manager") or by earning a "Master of Business Administration" (MBA). Conclusion: Management competence is essential in leading positions in clinical surgery today. The use of these skills is challenging in daily practice. Successfully applied, management competence not only guarantees comprehensive patient care and leadership of employees, but also provides satisfaction in leading positions of a surgical department.
