Abstract
AIM Robotic techniques are being increasingly used in colorectal surgery. There is, however, a lack of training opportunities and structured training programmes. Robotic surgery has specific problems and challenges for trainers and trainees. Ergonomics, specific skills and user-machine interfaces are different from those in traditional laparoscopic surgery. The aim of this study was to establish expert consensus on the requirements for a robotic train-the-trainer curriculum amongst robotic surgeons and trainers. METHOD This is a modified Delphi-type study involving 14 experts in robotic surgery teaching. A reiterating 19-item questionnaire was sent out to the same group and agreement levels analysed. A consensus of 0.8 or higher was considered to be high-level agreement. RESULTS Response rates were 93-100% and most items reached high levels of agreement within three rounds. Specific requirements for a robotic faculty development curriculum included maximizing dual-console teaching, theatre team training, nontechnical skills training, patient safety, user-machine interface training and telementoring. CONCLUSION A clear need for the development of a train-the-trainer curriculum has been identified. Further research is needed to assess feasibility, effectiveness and clinical impact of a robotic train-the-trainer curriculum.

Abstract
Demographic changes in Germany means that nursing and medical care is becoming increasingly complex. This is especially true for intensive care. Despite the closure of hospitals in Germany, the number of beds in intensive care units rose between 2002 from 23,113 to 26,162 in 2010. At the same time the number of patients treated in intensive care units increased by 148,989 to 2,049,888. The increasing complexity requires specific education for nurses in intensive care based on a model of advanced nursing practice (ANP). Nursing experts who fulfill an advanced practise nursing are competent to make decisions autonomously and accountably within complex care situations. This includes decisions such as artificial ventilation, weaning, nutrition management and the management of delirium, wounds and pain. Nursing experts are responsible for specific clearly defined areas of care and initiate nurse-led services and practice. Scientific and research based evidence are transferred directly into health care practice and can be implemented directly. The DGF demands a scientific and with it academic development of critical care as advanced nursing practice based on a master level qualification. This also includes the request for expansion of competencies and roles and the assignment of decision making authority within complex health care situations and an orientation on the Competencies for European Critical Care Nurses of the European Federation of Critical Care Nursing Associations (EfCCNa).

Abstract
Dairy cattle experience metabolic stress during the transition from late gestation to early lactation resulting in higher risk for several economically important diseases (e.g. mastitis, metritis, and ketosis). Metabolic stress is described as a physiological state composed of 3 processes: nutrient metabolism, oxidative stress, and inflammation. Current strategies for monitoring transition cow nutrient metabolism include assessment of plasma non-esterified fatty acids and beta-hydroxybutyrate concentrations around the time of calving. Although this method is effective at identifying cows with higher disease risk, there is often not enough time to implement intervention strategies to prevent health disorders from occurring around the time of calving. Previously, we published predictive models for early lactation diseases at the individual cow level at dry-off. However, it is unknown if predictive probabilities from individual-level models can be aggregated to the cohort level to predict cohort-level incidence. Therefore, our objective was to test different data aggregation methods using previously published models that represented the 3 components of metabolic stress (nutrient metabolism, oxidative stress, and inflammation). We included 277 cows from five Michigan dairy herds for this prospective cohort study. On each farm, two to four calving cohorts were formed, totaling 18 cohorts. We measured biomarker data at dry-off and followed the cows until 30 days post-parturition for cohort disease incidence, which was defined as the number of cows: 1) having one or more clinical transition disease outcome, and/or 2) having an adverse health event (abortion or death of calf or cow) within each cohort. We tested three different aggregation methods that we refer to as the p-central, p-dispersion, and p-count methods. For the p-central method, we calculated the averaged predicted probability within each cohort. For the p-dispersion method, we calculated the standard deviation of the predicted probabilities within a cohort. For the p-count method, we counted the number of cows above a specified threshold of predicted probability within each cohort. We built four sets of models: one for each aggregation method and one that included all three aggregation methods (p-combined method). We found that the p-dispersion method was the only method that produced viable predictive models. However, these models tended to overestimate incidence in cohorts with low observed counts and underestimate risk in cohorts with high observed counts.

Abstract
BACKGROUND Despite rising incidence rates of colorectal malignancies, only a few prognostic tools have been implemented in proven clinical routine. Cell division and proliferation play a significant role in malignancies. In terms of colorectal cancer, the impact of proliferation associated proteins is controversially debated. The aim of our study was to examine the expression of topoisomerase II α and minichromosome maintenance protein 6 and to correlate these findings with the clinical data. METHODS Tissue samples of 619 patients in total were stained using the antibodies Ki-S4 and Ki-MCM6 targeting topoisomerase II α as well as minichromosome maintenance protein 6. The median rate of proliferation was correlated with clinical and follow up data. RESULTS The expression rate of minichromosome maintenance protein 6 is significantly higher than the proportion of topoisomerase II α in tumour cells (p < 0.001). A high expression of both proteins coincides with a beneficial outcome for the patient, indicating a favourable prognostic marker (p < 0.001 and p = 0.008). CONCLUSIONS We have demonstrated that high expression rates of proliferative markers is linked to a beneficial patient outcome. According to the general opinion, a high expression rate correlates with a poor patient outcome. In this study, we were able to refute this assertion.

Abstract
During the transition period, dairy cattle undergo tremendous metabolic and physiological changes to prepare for milk synthesis and secretion. Failure to sufficiently regulate these changes may lead to metabolic stress, which increases risk of transition diseases. Metabolic stress is defined as a physiological state consisting of 3 components: aberrant nutrient metabolism, oxidative stress, and inflammation. Current monitoring methods to detect cows experiencing metabolic stress involve measuring biomarkers for nutrient metabolism. However, these biomarkers, including non-esterified fatty acids, beta-hydroxybutyrate, and calcium are typically measured a few weeks before to a few days after calving. This is a retroactive approach, because there is little time to integrate interventions that remediate metabolic stress in the current cohort. Our objective was to determine if biomarkers of metabolic stress measured at dry-off are predictive of transition disease risk. We designed a prospective cohort study carried out on 5 Michigan dairy farms (N = 277 cows). We followed cows from dry-off to 30 days post-calving. Diseases and adverse outcomes were grouped in an aggregate outcome that included mastitis, metritis, retained placenta, ketosis, lameness, pneumonia, milk fever, displaced abomasum, abortion, and death of the calf or the cow. We used best subsets selection to select candidate models for four different sets of models: one set for each component of metabolic stress (nutrient metabolism, oxidative stress, and inflammation), and a combined model that included all 3 components. We used model averaging to obtain averaged predicted probabilities across each model set. We hypothesized that the averaged predictions from the combined model set with all 3 components of metabolic stress would be more effective at predicting disease than each individual component model set. The area under the curve estimated using receiver operator characteristic curves for the combined model set (0.93; 95% confidence interval [CI] = 0.90-0.96) was significantly higher compared with averaged predictions from the inflammation (0.87; 95% CI = 0.83-0.91), oxidative stress (0.78; 95% CI = 0.72-0.84), and nutrient metabolism (0.73; 95% CI = 0.67-0.79) model sets (p < 0.05). Our results indicate that it may be possible to detect cattle at risk for some transition diseases as early as dry-off. This has important implications for disease prevention, as earlier identification of cows at risk of health disorders will allow for earlier implementation of intervention strategies. A limitation of the current study is that we did not perform external validation. Future validation studies are needed to confirm our findings.

Abstract
For most people living with mental illnesses, participating in society is of existential importance; however, psychosocial care often fails to recognize its significance and therefore rarely includes the patient's interaction with society in the course of treatment. The reasons for this are both substantial and organizational in nature. The endless opportunities for participating in society, current areas as well as ways of taking part in social life even beyond the terms of the social legislative definition are, in addition to institutional variety and regional differences, all too often barriers to providing the very urgently needed support. Further aspects are insufficient knowledge of therapists about established options of rehabilitative treatment and about responsibilities related to participation in specialized training and further education for professional caregivers. The presented compass of participation for social integration of persons with mental illnesses starts at this point: it provides guidelines for psychiatric and psychotherapeutic practitioners, general practitioners as well as for physicians working in residential or day care institutions with a psychiatric and psychotherapeutic background. Both this article and planned online versions should help professionals to timely and successfully assist people, particularly those with severe mental illnesses, to navigate the broad spectrum of services for social and vocational integration in Germany.

Abstract
Background At the time of planned pancreatoduodenectomy patients frequently undergo exploratory laparotomy without resection, leading to delayed systemic therapy. This study aimed to develop and validate a prognostic model for the preoperative prediction of resectability of pancreatic head tumours. Methods This was a retrospective study of patients undergoing attempted resection for confirmed malignant tumours of the pancreatic head in a university hospital in Hannover, Germany. The prognostic value of patient and tumour characteristics was investigated in a multivariable logistic regression model. External validation was performed using data from two other centres. Results Some 109 patients were included in the development cohort, with 51 and 175 patients in the two validation cohorts. Eighty patients (73·4 per cent) in the development cohort underwent resection, and 37 (73 per cent) and 141 (80·6 per cent) in the validation cohorts. The main reasons for performing no resection in the development cohort were: local invasion of vasculature or arterial abutment (15 patients, 52 per cent), and liver (12, 41 per cent), peritoneal (8, 28 per cent) and aortocaval lymph node (6, 21 per cent) metastases. The final model contained the following variables: time to surgery (odds ratio (OR) 0·99, 95 per cent c.i. 0·98 to 0·99), carbohydrate antigen 19-9 concentration (OR 0·99, 0·99 to 0·99), jaundice (OR 4·45, 1·21 to 16·36) and back pain (OR 0·02, 0·00 to 0·22), with an area under the receiver operating characteristic (ROC) curve (AUROC) of 0·918 in the development cohort. AUROC values were 0·813 and 0·761 in the validation cohorts. The positive predictive value of the final model for prediction of resectability was 98·0 per cent in the development cohort, and 91·7 and 94·7 per cent in the two external validation cohorts. [Corrections added on 18 July 2018, after first online publication: The figures for OR of the variables time to surgery and CA19-9 in the abstract and in Table 3 and Table 4 were amended from 1·00 to 0·99]. Conclusion For preoperative prediction of the likelihood of resectability of pancreatic head tumours, this validated model is a valuable addition to CT findings.

Abstract
ZusammenfassungDie Psychiatrische Versorgungslandschaft steht vor großen Herausforderungen: einerseits steigt die Inanspruchnahme psychiatrisch-psychotherapeutischer Leistungen, andererseits wird auf diesem Hintergrund eine teilweise schon reale und zum Teil noch erwartete Ressour-cenverknappung deutlich. Seit Jahren gibt es Bestrebungen, die Ausgabensteigerung zu begrenzen. Ebenfalls seit Jahren zeigt sich ein Mangel an qualifizierten Mitarbeitern, der in der Berufsgruppe der Ärzte vielfach schon spürbar ist, in der Pflege für die nahe Zukunft prognostiziert wird. Hinzu kommt der vielbeschriebene demografische Wandel, der neben einer Zunahme von älteren Nutzern auch mit einer Zunahme an alternden Helfern einhergehen wird. Aufbauend auf diesen Herausforderungen beschreibt der Beitrag die Aspekte, die für ein zukunftsfähiges psychiatrisches Versorgungssystem aus Sicht der Autoren zu bedenken sind und wendet sich dann bestehenden Versorgungsmodellen zu, die als Antwortversuche auf diese Fragestellungen verstanden werden können. Zum Abschluss werden die sich daraus entwickelnden Zukunftsperspektiven umrissen und ein Ausblick auf eine gesundheitsfördernde psychiatrische Versorgungslandschaft gegeben.

Abstract
Pylorus-preserving pancreaticoduodenectomy is one of the most complex procedures in general surgery. Laparoscopic pancreaticoduodenectomy was initially described in 1994; however, its worldwide distribution is so far limited to only a few specialist centers. Robotic surgery using the DaVinci® system can overcome many limitations of laparoscopic surgery. The system is a promising tool for a more widespread introduction of minimally invasive surgery for pancreatic diseases. Mortality rates of 0-5% and pancreatic fistula rates of 0-35% are described in the literature; therefore, thorough complication management is crucial in the postoperative course. The video presents a robotic pylorus-preserving pancreaticoduodenectomy for periampullary carcinoma in a female patient.

Abstract
Background We present a rare case of an antegrade intussusception of the remnant stomach four years after a biliopancreatic diversion. Case presentation A 55-year-old female patient presented with epigastric pain in our emergency room. Laboratory parameters showed an anemia as well as elevated transaminases and hyperbilirubinemia. The CT scan showed an intussusception of the remnant stomach into the duodenum followed by cholestasis. At laparotomy the remnant stomach was resected. Conclusion Bowel obstruction and intussusception after bariatric surgery are a rare but often unrecognized complication. Sonography as well as a CT scan should be performed. The exploratory laparoscopy however is the most valuable diagnostic tool in patients with suspected intussusception, due to the high rate of non-specific symptoms and misinterpreted radiographic investigations.

Abstract
Aims Guided growth using eight-plates is commonly used for correction of angular limb deformities in growing children. The principle is of tethering at the physeal periphery while enabling growth in the rest of the physis. The method is also applied for epiphysiodesis to correct limb-length discrepancy (LLD). Concerns have been raised regarding the potential of this method to create an epiphyseal deformity. However, this has not been investigated. The purpose of this study was to detect and quantify the occurrence of deformities in the proximal tibial epiphysis following treatment with eight-plates. Patients and Methods A retrospective study was performed including 42 children at a mean age of 10.8 years (3.7 to 15.7) undergoing eight-plate insertion in the proximal tibia for correction of coronal plane deformities or LLD between 2007 and 2015. A total of 64 plates were inserted; 48 plates (34 patients) were inserted to correct angular deformities and 16 plates (8 patients) for LLD. Medical records, Picture Archive and Communication System images, and conventional radiographs were reviewed. Measurements included interscrew angle, lateral and medial plateau slope angles measured between the plateau surface and the line between the ends of the physis, and tibial plateau roof angle defined as 180° minus the sum of both plateau angles. Measurements were compared between radiographs performed adjacent to surgery and those at latest follow-up, and between operated and non-operated plateaus. Statistical analysis was performed using BMDP Statistical Software. Results Slope angle increased in 31 (49.2%) of operated epiphyses by a mean of 5° (1° to 23°) compared with 29 (31.9%) in non-operated epiphyses (p = 0.043). Roof angle decreased in 29 (46.0%) of operated tibias and in 25 (27.5%) of non-operated ones by a mean of 5° (1° to 18°) (p = 0.028). Slope angle change frequency was similar in patients with LLD, varus and valgus correction (p = 0.37) but roof angle changes were slightly more frequent in LLD (p = 0.059) and correlated with the change in inter screw angles (r = 0.74, p = 0.001). Conclusion The use of eight-plates in the proximal tibia for deformity correction and limb-length equalization causes a change in the bony morphology of the tibial plateau in a significant number of patients and the effect is more pronounced in the correction of LLD.

Abstract
BACKGROUND The goal of rapid sequence induction (RSI) in cases of emergency situations is to secure the airway as quickly as possible to prevent pulmonary aspiration of gastric contents; however, the technique itself is not standardized. For example, the choice of drugs, application of cricoid pressure and the patient position remain controversial. A survey of emergency medical services (EMS) physicians throughout Germany was carried out to assess the different RSI techniques used and with respect to complying with the national guidelines for emergency airway management anesthesia and local standard operating procedures (SOP). MATERIAL AND METHODS Between 1 April 2017 and 31 May 2017, EMS medical directors in Germany were contacted and asked to distribute a 28-question online questionnaire to local EMS physicians. Of the questions 26 were multiple choice and 2 with plain text. After 6 weeks an e‑mail reminder was sent. In addition, the survey was distributed via social media to EMS physicians. RESULTS In total the survey was opened 2314 times and 1074 completed responses were received (completion rate 46%). Most of the participants were male (78%) and anesthesiologists (70%) and only one quarter had a local SOP for RSI. The most frequently used muscle relaxant was succinylcholine (62%) and over half of the participants reported using cricoid pressure (57%). There was a distinction between the specialist disciplines in the selection of drugs. Propofol was used most by anesthesiologists, while the others still used etomidate on a larger scale. Nearly 100% could fall back on supraglottic devices (one third laryngeal mask, two thirds laryngeal tube) but only 32.8% with the recommended esophageal drainage. A video laryngoscope was available to 51% of all EMS physicians surveyed. CONCLUSION The results of the survey demonstrate heterogeneity in RSI techniques used by EMS physicians in Germany. Medical equipment and safe care practices, such as labeling of syringes varied considerably between different service areas. The recommendations of the S1 national guidelines on emergency airway management and anesthesia should be adhered to together with the implementation of local SOPs.
