Abstract
Delirium is associated with long-term cognitive dysfunction and with increased brain atrophy. However, it is unclear whether these problems result from or predisposes to delirium. We aimed to investigate preoperative to postoperative brain changes, as well as the role of delirium in these changes over time. We investigated the effects of surgery and postoperative delirium with brain MRIs made before and 3 months after major elective surgery in 299 elderly patients, and an MRI with a 3 months follow-up MRI in 48 non-surgical control participants. To study the effects of surgery and delirium, we compared brain volumes, white matter hyperintensities and brain infarcts between baseline and follow-up MRIs, using multiple regression analyses adjusting for possible confounders. Within the patients group, 37 persons (12%) developed postoperative delirium. Surgical patients showed a greater decrease in grey matter volume than non-surgical control participants [linear regression: B (95% confidence interval) = -0.65% of intracranial volume (-1.01 to -0.29, P < 0.005)]. Within the surgery group, delirium was associated with a greater decrease in grey matter volume [B (95% confidence interval): -0.44% of intracranial volume (-0.82 to -0.06, P = 0.02)]. Furthermore, within the patients, delirium was associated with a non-significantly increased risk of a new postoperative brain infarct [logistic regression: odds ratio (95% confidence interval): 2.8 (0.7-11.1), P = 0.14]. Our study was the first to investigate the association between delirium and preoperative to postoperative brain volume changes, suggesting that delirium is associated with increased progression of grey matter volume loss.

Abstract
Postoperative delirium (POD) is a common and serious complication after surgery. It is associated with increased morbidity and mortality as well as neurocognitive disorder and associated loss of autonomy and increased need for care. As professionals, it is our duty to treat our patients in a holistic individual concept with the aim to reintegrate our patients into their home and social environment afterwards. In addition to preoperative and intraoperative interventions, postoperative prevention is of particular importance. This article focuses on non-pharmacological prevention strategies to avoid postoperative delirium and neurocognitive disorder in postoperative inpatient care. It is based on the "Evidence-based and consensus-based guideline on postoperative delirium". Thus, risk factors are addressed and non-pharmacological strategies are presented, which include reorientation, mobilization and nutritional support. Interprofessional cooperation plays just as important a role as the implementation of the listed preventive measures. Finally, the modified Hospital Elder Life Program is presented, which presents and applies preventive measures as a system-oriented and interdisciplinary concept, which "prevents functional decline and allows older adults to return home at the maximal level of independence". From our point of view, the training of a professional delirium team is a future-oriented complementary measure in the treatment concept of Perioperative Neurocognitive Disorders (PND), which finds its justification as an interface in the treatment of high-risk patients.

Abstract
BACKGROUND Frailty is a frequent and underdiagnosed functional syndrome involving reduced physiological reserves and an increased vulnerability against stressors, with severe individual and socioeconomic consequences. A routine frailty assessment was implemented at our preoperative anaesthesia clinic to identify patients at risk. OBJECTIVE This study examines the relationship between frailty status and the incidence of in-hospital postoperative complications in elderly surgical patients across several surgical disciplines. DESIGN Retrospective observational analysis. SETTING Single center, major tertiary care university hospital. Data collection took place between June 2016 and March 2017. PATIENTS Patients 65 years old or older were evaluated for frailty using Fried's 5-point frailty assessment prior to elective non-cardiac surgery. Patients were classified into non-frail (0 criteria, reference group), pre-frail (1-2 positive criteria) and frail (3-5 positive criteria) groups. MAIN OUTCOME MEASURES The incidence of postoperative complications was assessed until discharge from the hospital, using the roster from the National VA Surgical Quality Improvement Program. Propensity score matching and logistic regression analysis were performed. RESULTS From 1186 elderly patients, 46.9% were classified as pre-frail (n = 556), and 11.4% as frail (n = 135). The rate of complications were significantly higher in the pre-frail (34.7%) and frail groups (47.4%), as compared to the non-frail group (27.5%). Similarly, length of stay (non-frail: 5.0 [3.0;7.0], pre-frail: 7.0 [3.0;9.0], frail 8.0 [4.5;12.0]; p < 0.001) and discharges to care facilities (non-frail:1.6%, pre-frail: 7.4%, frail: 17.8%); p < 0.001) were significantly associated with frailty status. After propensity score matching and logistic regression analysis, the risk for developing postoperative complications was approximately two-fold for pre-frail (OR 1.78; 95% CI 1.04-3.05) and frail (OR 2.08; 95% CI 1.21-3.60) patients. CONCLUSIONS The preoperative frailty assessment of elderly patients identified pre-frail and frail subgroups to have the highest rate of postoperative complications, regardless of age, surgical discipline, and surgical risk. Significantly increased length of hospitalisation and discharges to care facilities were also observed. Implementation of routine frailty assessments appear to be an effective tool in identifying patients with increased risk. Now future studies are needed to investigate whether patients benefit from optimization of patient counselling, process planning, and risk reduction protocols based on the application of risk stratification.

Abstract
Postoperative delirium (POD) is an acute change in the mental state with consciousness and attention deficits. It is a common complication after surgical procedures and can have serious consequences. Thus, the evidence- and consensus-based guidelines for POD appeals with the highest recommendation level that patients be regularly screened for delirium in the postoperative phase, from the recovery room to the fifth postoperative day and at least once per shift, using a validated test instrument for the detection of POD. In 2014, Marcantonio et al. published the 3D-CAM (3-Minute Diagnostic Interview for CAM-defined Delirium). In the 3D-CAM, the algorithm of the Confusion Assessment Method (CAM) is maintained by using individual elements that operationalize the evaluation of the criteria. Therefore, it requires less training, be faster to use, and, due to a standardized approach, has less interrater variability than the CAM, whereas the high sensitivity and specificity are maintained. Our goal was to translate the 3D-CAM from English to German, so as to make this instrument available to German-speaking countries. The translation of the 3D-CAM was based on the 2005 published guideline on Translation and Cultural Adaptation of Patient Reported Outcome Measures of the International Society for Pharmacoeconomics and Outcome Research. Three independent forward translations were harmonized to a preliminary translation, which then was translated back into the original language. Original authors reviewed the back translation. According to a cognitive debriefing, the translation was revised and in addition was adapted for use in the recovery room. Due to close contact with the original authors during the translation process, it was possible to ensure that the contents of the test instrument were remained intact during the translation process.

Abstract
ZusammenfassungFrailty (Gebrechlichkeit) ist eine Einschränkung der physiologischen Reserve bei älteren Patienten mit schwerwiegenden individuellen und sozioökonomischen Folgen. Multiple Aspekte der Patientenbehandlung sowie das Outcome werden durch Frailty nachhaltig beeinflusst. Obwohl mehr als 60 Messinstrumente existieren, sind die Erfassung und Berücksichtigung funktioneller Assessments in der klinischen Routine unzureichend umgesetzt. Das interdisziplinäre und interprofessionelle Verständnis, warum und wie Frailty beurteilt werden sollte, ist die Grundlage für die dauerhafte Implementierung. Der Artikel zeigt die Auswirkungen von Frailty und Vorteile einer Früherkennung auf und gibt einen Überblick über die wichtigsten Instrumente, die in der Frailty-Erkennung und -Bewertung verwendet werden können. Die frühe präoperative Detektion bietet ein vielfältiges Optimierungspotenzial für die peri- und intraoperative Versorgung. Verschiedene Frailty-Assessment-Tools körperlicher, kognitiver und psychosozialer Domänen werden vorgestellt und diskutiert. Frailty-Assessments variieren immens in Bezug auf die erforderliche Zeit, die Ausrüstung und das Fachwissen zur Durchführung. Wir empfehlen mindestens einen Test für die einzelnen Dimensionen von Frailty, um ein holistisches Bild der geriatrischen Patienten zu erhalten. Die Bewertung von Frailty sollte übergreifend in die interdisziplinären Strukturen der klinischen Routine implementiert werden, um die Patientensicherheit sowie das kurz- und langfristige Outcome zu verbessern.

Abstract
Mammalian nuclear receptors (NRs) are transcription factors regulating the expression of target genes that play an important role in drug metabolism, transport, and cellular signaling pathways. The orphan and structurally unique receptor small heterodimer partner 1 (syn NR0B2) is not only known for its modulation of drug response, but has also been reported to be involved in hepatocellular carcinogenesis. Indeed, previous studies show that NR0B2 is downregulated in human hepatocellular carcinoma, suggesting that NR0B2 acts as a tumor suppressor via inhibition of cellular growth and activation of apoptosis in this tumor entity. The aim of our study was to elucidate whether NR0B2 may also play a role in other tumor entities. Comparing NR0B2 expression in renal cell carcinoma and adjacent nonmalignant transformed tissue revealed significant downregulation in vivo. Additionally, the impact of heterologous expression of NR0B2 on cell cycle progression and proliferation in cells of renal origin was characterized. Monitoring fluorescence intensity of resazurin turnover in RCC-EW cells revealed no significant differences in metabolic activity in the presence of NR0B2. However, there was a significant decrease of cellular proliferation in cells overexpressing this NR, and NR0B2 was more efficient than currently used antiproliferative agents. Furthermore, flow cytometry analysis showed that heterologous overexpression of NR0B2 significantly reduced the amount of cells passing the G1 phase, while on the other hand, more cells in S/G2 phase were detected. Taken together, our data suggest that downregulation of NR0B2 may also play a role in renal cell carcinoma development and progression.
