Abstract
BACKGROUND Various prognostic prediction models exist for evaluating the risk of nausea and vomiting in the postoperative period (PONV). So far, no systematic comparison of these prognostic scores is available. METHOD A systematic literature search was carried out in seven medical databases to find publications on prognostic PONV models. Identified scores were assessed against prospectively defined quality criteria, including generalizability, validation and clinical relevance of the models. RESULTS The literature search revealed 62 relevant publications with a total of 81,834 patients which could be assigned to 8 prognostic models. The simplified Apfel score performed best, primarily because it was extensively validated. The Van den Bosch score and Sinclair score tied for second place. The simplified Koivuranta score was in third place. CONCLUSION The qualitative analysis highlights the strengths and weaknesses of each prediction system based on predetermined standardized quality criteria.

Abstract
Acute aortic diseases represent a group of complex severe and often fatal medical conditions. Although they are significantly rarer than cardiac or thromboembolic events, they are an important differential diagnosis to be ruled out, e.g., in the clinical work-up of acute chest pain.Treatment, especially surgical interventions, depends on the progression, extent and size of the pathology and whenever possible should be performed in specialized centers with the appropriate experience.Intensive care monitoring is advisable as a range of peracute complications can occur even in initially stable patients. Depending on the clinical presentation and affected structures, a number of severe complications need to be anticipated by critical care physicians. Additionally, a notable symptom is severe and refractory hypertension, especially in the acute phase. This article provides a summary of the most frequent clinical pictures and corresponding treatment options. Furthermore, the principles of initial patient stabilization and treatment as well as the perioperative management of complex surgical procedures on the aorta are discussed.

Abstract
BACKGROUND Globally, the ages at pubertal onset for girls and boys have been decreasing during recent decades, partly attributed to excess body fat accumulation. However, a growing body of literature has recognized that endocrine disrupting chemicals (EDCs) may play an important role in this global trend, but the association has not yet been fully established. OBJECTIVE AND RATIONALE EDCs can interfere with normal hormone function and metabolism and play a role in pubertal onset. We aimed to systematically identify and evaluate the current evidence on the timing of pubertal onset in girls and boys following prenatal or postnatal exposures to xenobiotic EDCs. SEARCH METHODS Following PRISMA guidelines, we performed a systematic literature search of original peer-reviewed publications in the PubMed database through a block search approach using a combination of index MeSH and free text search terms. Publications were considered if they covered biomarkers of prenatal or postnatal exposures to xenobiotic EDCs (European Commission's list of category 1 EDCs) measured in maternal or child biospecimen and pubertal onset defined by the progression of the following milestones (and assessed in terms of the following measures): menarche (age), thelarche (Tanner staging) and pubarche (Tanner staging), in girls, and genital stage (Tanner staging), testicular volume (ml) and pubarche (Tanner staging), in boys. OUTCOMES The literature search resulted in 703 references, of which we identified 52 publications fulfilling the eligibility criteria for the qualitative trend synthesis and 23 publications for the meta-analysis. The qualitative trend synthesis provided data on 103 combinations of associations between prenatal or postnatal exposure to EDC compounds groups and puberty outcomes and the meta-analysis enabled 18 summary risk estimates of meta-associations. WIDER IMPLICATIONS Statistically significant associations in the qualitative trend synthesis suggested that postnatal exposure to phthalates may be associated with earlier thelarche and later pubarche. However, we did not find consistent evidence in the meta-analysis for associations between timing of pubertal onset in girls and boys and exposures to any of the studied xenobiotic EDCs. We were not able to identify specific pre- or postnatal windows of exposure as particularly critical and susceptible for effects of EDCs. Current evidence is subject to several methodological challenges and inconsistencies and evidence on specific exposure-outcome associations remains too scarce to firmly confirm EDC exposure as a risk factor for changes in age of pubertal onset in the general child population. To create a more uniform foundation for future comparison of evidence and to strengthen pooled studies, we recommend the use of more standardized approaches in the choice of statistical analyses, with exposure transformations, and in the definitions and assessments of puberty outcomes. The impact of mixtures of EDC exposures on the association also remains unestablished and would be valuable to elucidate for prenatal and postnatal windows of exposure. Future large, longitudinal epidemiological studies are needed to clarify the overall association.

Abstract
BACKGROUND Administration of opioids to suppress pain plays a major role in modern anesthesia. Measuring depth of hypnosis and neuromuscular recovery are already well established, and devices for pain monitoring are available. Nonetheless pain monitoring is rare in clinical practice. Recently, the pain monitoring device PMD200 (Medasense Biometrics™ , Israel) was introduced. It non-invasively measures heart rate, heart rate variability, skin resistance, resistance variability, temperature and movement to calculate a nociception level (NoL) index. The NoL index range starts at zero, which is equivalent to being painless, and goes up to a value of 100. The validity and reliability of NoL monitoring is the content of current studies. OBJECTIVE We tested the hypothesis if the use of the PMD200 significantly reduces opioid consumption during da Vinci prostatectomy. MATERIAL AND METHODS A total of 50 male patients were included in this randomized, single blinded study. Exclusion criteria were arrhythmia because the pain monitoring device requires a sinus rhythm for reliable results. Patients received a weight-adjusted sufentanil bolus (0.3 µg/kg ideal body weight) during induction of anesthesia. Additionally, they received 10 µg of sufentanil before skin incision. Both groups received total intravenous anesthesia with propofol and continuous muscle relaxation through cis-atracurium. In the control group (CONT; n = 26), a standardized sufentanil bolus of 10 µg were administered by common criteria (heart rate/blood pressure increase, lacrimation, gut feeling) at the anesthesiologist's discretion. In the intervention group (INT; n = 24), patients received the standardized sufentanil bolus when the NoL index was above 25 for 2 min, which corresponds to the manufacturer's recommendation. The NoL index and bolus administrations were recorded for every patient. In the control group, the display of the pain monitor showing the NoL index was not visible for the anesthesiologist. Postoperatively, pain/nausea scores and piritramide consumption were taken every 10 min for 1h in the recovery room. None of the patients had prior chronic pain with long-term use of painkillers. Statistics were done using Mann-Whitney U‑test, Kolmogorov-Smirnov test and Levene test. RESULTS Sufentanil bolus administrations, normalized for duration of surgery, were not significantly lower in the intervention group (p = 0.065). We noticed a significant difference in variation of opioid administrations (p = 0.033). Sufentanil boluses per hour in the INT were normally distributed (p = 0.2), whereas in CONT they were not (p = 0.003). Postoperative data like nausea, opioid consumption and pain scale showed no differences between groups. CONCLUSION The use of PMD200 did not significantly reduce cumulative opioid consumption. Following on we must reject the initial hypothesis. The difference in sufentanil bolus variances may point to an individualized antinociceptive therapy when NoL monitoring is used. We suppose patients with high opioid demands are detected and patients with low opioid demands did not receive unnecessary opioids. This assumption is only true if the PMD200 measures the entity pain. Further studies with more participants during surgery with higher tissue damage could lead to more convincing data and conclusions.

Abstract
Im Jahr 2019 starben in Deutschland 756 Menschen, während sie auf der Warteliste für ein Spenderorgan standen. Sowohl im Eurotransplant-Verbund als auch weltweit gehört Deutschland mit 10,8 Organspendern/Mio. Einwohner im Jahr 2019 zur Schlussgruppe. Sämtliche politischen Versuche, die Spenderzahlen zu steigern, scheinen bislang ohne Effekt geblieben zu sein. Darüber hinaus hat die durch das „severe acute respiratory syndrome coronavirus 2“ (SARS-CoV-2) ausgelöste Pandemie zum weiteren Rückgang der Spenderzahlen geführt. Der Intensivmedizinerin kommt im Prozess der Erkennung möglicher Spender sowie als erste Ansprechpartnerin für die Angehörigen eine zentrale Rolle zu. Jedoch existieren nicht nur in den gesellschaftlichen und medialen Diskussionen um das Thema Organspende viele Unklarheiten, sondern auch bei den intensivmedizinisch tätigen Ärzten. Viele Annahmen und Hypothesen, die mit den niedrigen Spenderzahlen in einen Zusammenhang gebracht werden, lassen sich wissenschaftlich jedoch nicht belegen und sollen in diesem Beitrag diskutiert werden.

Abstract
STUDY QUESTION Is there an association between prenatal exposure to stressful life events and age at menarche, and does childhood BMI mediate this association? SUMMARY ANSWER Girls exposed to prenatal stress had a slightly earlier age at menarche, but this association did not show a dose-response effect and was not mediated by childhood offspring BMI. WHAT IS ALREADY KNOWN Prenatal stress may impact on reproductive function in females including age at menarche, but human data are very limited. High childhood BMI is known to be associated with earlier age at menarche. Only one small study has measured the association between maternal stress and age at menarche and reported that childhood BMI mediated the association between maternal stress and earlier age at menarche. However, neither maternal stress nor age at menarche was prospectively recorded and the study was limited to 31 mother-daughter pairs. STUDY DESIGN, SIZE, DURATION The Raine Study is a large prospective population-based pregnancy cohort study (n = 1414 mother-daughter pairs) continuously followed from prenatal life through to adolescence. In the present study, we examined the association between exposure to maternal stressful life events during early, late and total gestation and age at menarche in offspring using 753 mother-daughter pairs with complete case information. PARTICIPANTS/MATERIALS, SETTING, METHODS Mothers prospectively reported stressful life events during pregnancy at 18 and 34 weeks using a standardized 10-point questionnaire. Exact date of menarche was assessed using a purpose-designed questionnaire at 8, 10, 14 and 17 years of age. Complete information on exposure, outcome and confounding variables was obtained from 753 mothers-daughter pairs. Multivariate linear regression complete case analysis was used to examine associations between maternal stressful life event exposure and age at menarche. Potential selection bias was evaluated using multiple imputations (50 datasets). The mediating effects of offspring childhood BMI (ages 5, 8, or 10 years) on these associations were measured in separate sub-analyses. MAIN RESULTS AND ROLE OF CHANCE Most (580/753, 77%) daughters were exposed to at least one prenatal stressful life event. Exposure to maternal stressful life events during the entire pregnancy was associated with a non-linear earlier age at menarche. Exposure to one event and two or more psychological stressful events was associated with a 3.5 and 1.7-month earlier onset of puberty, respectively when compared to the reference group with no exposure maternal stressful life events. The estimates from multiple imputation with 50 datasets were comparable with complete case analysis confirming the existence of an underlying effect. No separate significant effects were observed for exposure during early or late gestation. The association between prenatal stressful events and age at menarche was not mediated by childhood BMI in the offspring. LIMITATIONS, REASONS FOR CAUTION Stressful life events may have affected pregnant women in different ways and self-perceived maternal stress severity may have provided a more precise estimate of gestational psychological stress. The observed non-linear U-shape of the association between maternal psychological stress and age at menarche did not reflect a dose-response. This suggests that the first exposure to prenatal stress exerts a greater effect on fetal reproductive development. A potential mechanism is via dramatic initial activation of the hypothalamic-pituitary-adrenal (HPA) axis following the first stressful life event which is greater than that observed following subsequent exposure to two or more maternal stressful life events. Whilst we adjusted for a priori chosen confounders, we cannot exclude residual confounding or confounding by factors we did not include. Maternal age at menarche was not available so the effects of familial history/genetics could not be assessed. There was a large loss due to the number of girls with no information on date of menarche and missing confounder information implying risk of selection bias and multiple imputation analyses did not fully exclude this risk (similar direction but slightly weaker estimate magnitude). WIDER IMPLICATIONS OF THE FINDINGS Menarche is a sentinel reproductive event and earlier age at menarche carries implications for psychological, social and reproductive health and for long-term risk of common non-communicable diseases. Understanding the factors regulating age at menarche has extensive health implications. This is the first population-based cohort study in humans to demonstrate that prenatal psychological stress might directly modify age at menarche.

Abstract
BACKGROUND Sympathomimetic drugs are a therapeutic cornerstone for the management of hypotensive states like intraoperative hypotension (IOH). While cafedrine/theodrenaline (C/T) is widely used in Germany to restore blood pressure in patients with IOH, more research is required to compare its effectiveness with alternatives such as ephedrine (E) that are more commonly available internationally. METHODS HYPOTENS (NCT02893241, DRKS00010740) was a prospective, national, multicenter, open-label, two-armed, non-interventional study that compared C/T with E for treatment of IOH. We describe a prospectively defined cohort of patients ≥50 years old with comorbidities undergoing general anesthesia induced with propofol and fentanyl. Primary objectives were to examine treatment precision, rapidity of onset and the ability to restore blood pressure without relevant increases in heart rate. Secondary endpoints were treatment satisfaction and the number of required additional boluses or other accompanying measures. RESULTS A total of 1496 patients were included in the per protocol analysis. Overall, effective stabilization of blood pressure was achieved with both C/T and E. Post-hoc analysis showed that blood pressure increase from baseline was more pronounced with C/T. Fewer additional boluses or other accompanying measures were required in the C/T arm. The incidence of tachycardia was comparable between groups. Post-hoc analysis showed that E produced dose-dependent elevated heart rate values. By contrast, heart rate remained stable in patients treated with C/T. Physicians reported a higher level of treatment satisfaction with C/T, with a higher proportion of anesthetists rating treatment precision and rapidity of onset as good or very good when compared with E. CONCLUSION Neither drug was superior in restoring blood pressure levels; however, post-hoc analyses suggested that treatment is more goal-orientated and easier to control with C/T. Heart rate was shown to be more stable with C/T and fewer additional interventions were required to restore blood pressure, which could have contributed to the increased treatment satisfaction reported by anesthetists using C/T.

Abstract
BACKGROUND PCOS is the most common endocrine disorder in reproductive age women. The origins of PCOS are unknown but experimental and limited human evidence suggests that greater prenatal exposure to androgens may predispose to PCOS. Experimental evidence suggests that maternal stressors may affect reproductive function in the offspring via changes in prenatal androgen exposure. In this present study, we aim to investigate whether maternal stressful life events during pregnancy are associated with polycystic ovary morphology (PCOM) or polycystic ovary syndrome (PCOS) in adolescent offspring. METHOD In a large population-based pregnancy cohort study (The Raine Study) continuously followed from prenatal life through to adolescence we examined the association between maternal stressful life events during pregnancy in both early and late gestation, and subsequent circulating concentrations of ovarian and adrenal androgens, PCOM and PCOS in the normal menstrual cycle of offspring age 14-16 years. Maternal stressful life events were prospectively recorded during pregnancy at 18 and 34 weeks using a 10-point questionnaire. Female offspring (n = 223) completed a questionnaire about their menstrual cycles, underwent a clinical examination for hirsutism (Ferriman-Gallwey score) and transabdominal pelvic ultrasound examination to determine ovarian morphology according to standardized criteria for classification of PCOM. Plasma samples were obtained at day 2-6 of the normal menstrual cycle for measurement of androgens. PCOM was defined according to the international consensus definition, 2003 and the evidence-based guideline for the assessment and management of PCOS, 2018. PCOS was diagnosed according to Rotterdam criteria and National Institute of Health (NIH) criteria. Multivariate linear and logistic regression analyses were used to examine the associations between maternal stressful life event exposure and ovarian morphology (PCOM), circulating ovarian and adrenal androgens (clinical and biochemical hyperandrogenism (hirsutism)) and presence of PCOS. RESULTS Of 223 recruited adolescent girls, 78 (35.9%) and 68 (31.3%) had PCOM by the 2003 and 2018 criteria respectively, while 66 (29.6%) and 37 (16.6%) had PCOS, using Rotterdam and NIH criteria, respectively. Most girls (141/223, 63.2%) were exposed to at least one stressful life event in early gestation and around half (121/223, 54.3%) were exposed to at least one stressful life event in late gestation. Maternal stressful life events in early gestation were associated with a statistically significant lower prevalence of PCOM when applying the 2003 criteria [adjusted odds ratio [aOR] and 95% confidence intervals (CI): 0.74 (95% CI: 0.55; 0.99)], and a similar association was detected when applying the 2018 PCOM criteria (aOR, 0.69, 95% CI: 0.50; 0.95)]. Maternal stressful life events in early gestation were also associated with lower circulating concentrations of testosterone (β = -0.05, 95% CI: -0.09; -0.004) and androstenedione (β = -0.05, 95% CI: -0.10; -0.002) in the offspring. No similar effects for PCOM or circulating androgens were detected in late gestation. No statistically significant associations between maternal stressful life events in early or late gestation with PCOS (neither Rotterdam nor NIH criteria) in adolescence were detected. The prospective collection of maternal stressful life events during both early and late gestation and direct measurement of PCOM, PCOS and circulating androgens in adolescence and key co-variates implies minimal possibility of recall, information bias and selection bias. CONCLUSION Maternal exposure to stressful life events in early gestation is associated with significantly reduced circulating ovarian and adrenal androgen concentrations in adolescence (testosterone and androstenedione), and an indication of fewer cases of polycystic ovary morphology (PCOM) defined by the 2003 international consensus definition and by the 2018 international evidence-based guideline, but has no effect on polycystic ovary syndrome (PCOS), diagnosed using either Rotterdam or NIH criteria.

Abstract
Drawing on the evolution of socio-geographical imaginaries of scholarly journals published in Chile, this article provides a picture of the socio-historical trajectories of internationalization of scholarly journals and communities in that part of the (semi-)periphery of science. In order to break with the presentism of many contemporary discussions, the analysis covers a relatively long period of time, from the end of the nineteenth century until the first decades of the twenty-first century. However, based on an inductive analysis of the journals, the article particularly focuses on the rise of nationalist and regionalist orientations in the late nineteenth and early twentieth centuries and the intensification of the pressures for internationalization in more recent decades. Building on the findings, the article concludes highlighting key elements and making some general observations on the internationalization processes in the semi-periphery of science.

Abstract
BACKGROUND AND PURPOSE Recent observations linked coronavirus disease 2019 (COVID-19) to thromboembolic complications possibly mediated by increased blood coagulability and inflammatory endothelial impairment. We aimed to define the risk of acute stroke in patients with severe and non-severe COVID-19. METHODS We performed an observational, multicenter cohort study in four participating hospitals in Saxony, Germany to characterize consecutive patients with laboratory-confirmed COVID-19 who experienced acute stroke during hospitalization. Furthermore, we conducted a systematic review using PubMed/MEDLINE, Embase, Cochrane Library and bibliographies of identified papers following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines including data from observational studies of acute stroke in COVID-19 patients. Data were extracted by two independent reviewers and pooled with multicenter data to calculate risk ratios (RRs) and 95% confidence intervals (95% CIs) for acute stroke related to COVID-19 severity using a random-effects model. Between-study heterogeneity was assessed using Cochran's Q and I2 statistics. International Prospective Register of Systematic Reviews registration number: CRD42020187194. RESULTS Of 165 patients hospitalized for COVID-19 (49.1% males, median age = 67 years [57-79 years], 72.1% severe or critical) included in the multicenter study, overall stroke rate was 4.2% (95% CI: 1.9-8.7). Systematic literature search identified two observational studies involving 576 patients that were eligible for meta-analysis. Amongst 741 pooled COVID-19 patients, overall stroke rate was 2.9% (95% CI: 1.9-4.5). Risk of acute stroke was increased for patients with severe compared to non-severe COVID-19 (RR = 4.18, 95% CI: 1.7-10.25; P = 0.002) with no evidence of heterogeneity (I2 = 0%, P = 0.82). CONCLUSIONS Synthesized analysis of data from our multicenter study and previously published cohorts indicates that severity of COVID-19 is associated with an increased risk of acute stroke.

Abstract
The 2018 drought was one of the worst European droughts of the twenty-first century in terms of its severity, extent and duration. The effects of the drought could be seen in a reduction in harvest yields in parts of Europe, as well as an unprecedented browning of vegetation in summer. Here, we quantify the effect of the drought on net ecosystem exchange (NEE) using five independent regional atmospheric inversion frameworks. Using a network of atmospheric CO2 mole fraction observations, we estimate NEE with at least monthly and 0.5° × 0.5° resolution for 2009–2018. We find that the annual NEE in 2018 was likely more positive (less CO2 uptake) in the temperate region of Europe by 0.09 ± 0.06 Pg C yr−1 (mean ± s.d.) compared to the mean of the last 10 years of −0.08 ± 0.17 Pg C yr−1, making the region close to carbon neutral in 2018. Similarly, we find a positive annual NEE anomaly for the northern region of Europe of 0.02 ± 0.02 Pg C yr−1 compared the 10-year mean of −0.04 ± 0.05 Pg C yr−1. In both regions, this was largely owing to a reduction in the summer CO2 uptake. The positive NEE anomalies coincided spatially and temporally with negative anomalies in soil water. These anomalies were exceptional for the 10-year period of our study. This article is part of the theme issue ‘Impacts of the 2018 severe drought and heatwave in Europe: from site to continental scale’.

Abstract
BACKGROUND Besides public awareness and specialist knowledge and training of physicians, their self-confidence plays a key role for clinical decision-making in the respective area. OBJECTIVE This exploratory study investigated the influence of the discipline on differences in self-confidence in dealing with antibiotics and in the self-rated knowledge. METHODS In 2015 the multi-institutional reconnaissance of practice with multiresistant bacteria (MR2) questionnaire containing items on antibiotic prescription and multiresistant pathogens was sent out to 1061 physicians working in departments for internal medicine, general surgery, gynecology and obstetrics and urology. In 2017 a similar MR2 survey was sent to 1268 specialist and assistant physicians in anesthesiology in Germany. Besides demographic data 4 items on self-confidence in the use of antibiotic treatment and 11 items concerning self-rated knowledge about rational antibiotic therapy and multiresistant pathogens were included in the present analysis. Logistic regression analysis, the χ2-test and the Kruskal-Wallis test were used for statistical analysis of the influence of the discipline on these items. RESULTS The response rates were 43% (456 out of 1061) from the non-anesthetists and 56% (705 out of 1268) from the anesthetists. Of the non-anesthetists 44% and 57% of the anesthetists had had no advanced training on antibiotic stewardship during the year before the study. In the overall analysis anesthetists (mean±SD: 2.53±0.54) were significantly less self-confident about antibiotics than colleagues from other departments (internal medicine: 3.10±0.50, general surgery: 2.97±0.44, gynecology and obstetrics: 3.12±0.42 and urology: 3.15±0.44) in the unadjusted (all p<0.001) and adjusted comparison. The analysis of self-rated knowledge about rational antibiotic prescription showed similar results. Senior consultant status and advanced training in infectiology were significantly associated with self-confidence and self-rated knowledge about antibiotics. CONCLUSION Anesthetists showed significantly less self-confidence in dealing with antibiotics than colleagues from other disciplines. Advanced training on a rational prescription of antibiotics was associated with a greater self-confidence, so that the implementation of compulsory courses on rational antibiotic stewardship in the respective residency curriculum needs to be considered.

Abstract
This review assesses four interrelating aspects of patient-controlled analgesia (PCA), a long-standing and still widely used concept for postoperative pain management. Over the years, anaesthesiologists and patients have appreciated the benefits of PCA alike. The market has seen new technologies leveraging noninvasive routes of administration and, thus, further increasing patient and staff satisfaction as well as promoting safety aspects. Pharmaceutical research focuses on the reduction or avoidance of opioids, side effects, and adverse events although influence of these aspects appears to be minor. The importance of education is still eminent, and new educational formats are tested to train healthcare professionals and patients likewise. New PCA technology can support the implementation of efficient processes to reduce workload and human errors; however, these new products come with a cost, which is not necessarily reflected through beneficial budget impact or significant improvements in patient outcome. Although first steps have been taken to better recognize the importance of postoperative pain management through the introduction of value-based reimbursement, in most western countries, PCA is not specifically compensated. PCA is still an effective and valued technique for postoperative pain management. Although there is identifiable potential for future developments in various aspects, this potential has not materialized in new products.

Abstract
BACKGROUND Electrical impedance tomography (EIT) with indicator dilution may be clinically useful to measure relative lung perfusion, but there is limited information on the performance of this technique. METHODS Thirteen pigs (50-66 kg) were anaesthetised and mechanically ventilated. Sequential changes in ventilation were made: (i) right-lung ventilation with left-lung collapse, (ii) two-lung ventilation with optimised PEEP, (iii) two-lung ventilation with zero PEEP after saline lung lavage, (iv) two-lung ventilation with maximum PEEP (20/25 cm H2O to achieve peak airway pressure 45 cm H2O), and (v) two-lung ventilation under unilateral pulmonary artery occlusion. Relative lung perfusion was assessed with EIT and central venous injection of saline 3%, 5%, and 10% (10 ml) during breath holds. Relative perfusion was determined by positron emission tomography (PET) using 68Gallium-labelled microspheres. EIT and PET were compared in eight regions of equal ventro-dorsal height (right, left, ventral, mid-ventral, mid-dorsal, and dorsal), and directional changes in regional perfusion were determined. RESULTS Differences between methods were relatively small (95% of values differed by less than 8.7%, 8.9%, and 9.5% for saline 10%, 5%, and 3%, respectively). Compared with PET, EIT underestimated relative perfusion in dependent, and overestimated it in non-dependent, regions. EIT and PET detected the same direction of change in relative lung perfusion in 68.9-95.9% of measurements. CONCLUSIONS The agreement between EIT and PET for measuring and tracking changes of relative lung perfusion was satisfactory for clinical purposes. Indicator-based EIT may prove useful for measuring pulmonary perfusion at bedside.

Abstract
ZusammenfassungIn Deutschland gibt es regionale Fahrverbote für ältere Dieselfahrzeuge ohne SCR-Katalysator bei Überschreitung der Grenzwerte für NO2. Dies hat zu einer intensiven Diskussion über die Rolle der Luftschadstoffe für die Gesundheit geführt. In der Replik wird dargestellt, dass die Daten zur Wirkung von Stickstoffdioxid (NO2) und Feinstaub (PM10 und PM2,5) nicht ausreichen, um die Fahrverbote zu begründen.Für NO2 gibt es passagere Reaktionen bei unbehandelten Asthmatikern ab 500 µg/m3. Die deutschen Grenzwerte (Jahresmittelwert 40 µg/m3) fußen im Wesentlichen auf einer Metaanalyse von 9 Studien aus Innenraumbelastungen wobei nur in 4 Studien NO2 gemessen wurde. In der großen europäischen Escape-Studie von 2014 wurde kein Einfluss von NO2 auf die Mortalität gefunden.Als Surrogatparameter für andere Schadstoffe ist NO2 ebenfalls nicht mehr geeignet, da seit Einführung der Partikelfilter bei Dieselautos (etwa ab 2000) der KFZ-Anteil am Feinstaub an der Straße unter 10 % liegt. Der Feinstaub besteht im Wesentlichen aus Aufwirbelung von mineralischen, organischen Bodensubstanzen sowie Reifenabrieb und wird am stärksten durch Wetterphänomene, vor allen Dingen durch Sonneneinstrahlung beeinflusst.Die Grenzwerte für NO2 und Feinstaub werden errechnet aus epidemiologischen Beobachtungsstudien. Es findet sich zumeist eine schwache Assoziation zwischen der Konzentra-tion und zahlreichen Erkrankung sowie der Mortalität. Epidemiologische Beobachtungsstudien erlauben nur die Bildung einer Hypothese. Permanente Wiederholungen der Beobachtungsstudien betätigen nur, dass manche gefundenen Phänomene nicht zufällig sind. Eine Kausalität kann daraus nicht abgeleitet werden, da es zahlreiche Erklärungsmodelle neben dem NO2 und Feinstaub gibt. Dazu wären Interventionsstudien im Niedrigdosisbereich sowie Tierexperimente erforderlich. Diese Daten fehlen nahezu komplett bzw. sind, soweit vorhanden, allesamt negativ.Nie diskutiert wird eine starke Widerlegung der Hypothese der Gefährdung von NO2 und Feinstaub im Grenzwertbereich durch das Inhalationsrauchen. Die Raucher stellen quasi einen inhalationstoxikologischen Großversuch dar. Der Zigarettenrauch enthält sehr hohe Feinstaub-, Stickstoffmonoxid- (NO) und NO2-Konzentrationen, die vom Organismus erstaunlich gut toleriert werden. Das hängt damit zusammen, dass NO ein Naturstoff ist, der in den Zellen oder auch in den Nasennebenhöhlen in z. T. sehr hohen Konzentrationen (über 30 000 µg/m3) vorkommt. Eines der Abbauprodukte von NO ist NO2, was im Wasser zu Nitrat und Nitrit disproportioniert wird. Ein Teil von NO2 wird zur Synthese von Fettsäuren verwendet.Zigaretten haben ein Kondensat von ca. 7 – 10 mg. Nimmt man als Vergleich eine lebenslange Dauerbelastung durch Feinstaub und NO2 in den Grenzwertkonzentrationen an, müssten alle Raucher nach wenigen Tagen bis Monaten zahlreiche Erkrankungen entwickeln, die dem Feinstaub und NOx angelastet werden. Auch die Mortalität müsste drastisch erhöht sein; nahezu alle Raucher müssten bereits nach 1 packyear verstorben sein. Der Unterschied wird noch größer, wenn man die nachgewiesene Toxizität und Kanzerogenität des Zigarettenrauchs im Vergleich zu dem i. d. R. deutlich weniger gefährlichen Feinstaub an der Straße ins Verhältnis setzt.

Abstract
BACKGROUND Dural puncture, paraesthesia and vascular puncture are the most common complications of epidural catheter insertion. Their association with variation in midline needle insertion depth is unknown. OBJECTIVE This study evaluated the risk of dural and vascular punctures and the unwanted events paraesthesia and multiple skin punctures related to midline needle insertion depth. MATERIAL AND METHODS A total of 14,503 epidural catheter insertions including lumbar (L1-L5; n = 5367), low thoracic (T7-T12, n = 8234) and upper thoracic (T1-T6, n = 902) insertions, were extracted from the German Network for Regional Anaesthesia registry between 2007 and 2015. The primary outcomes were compared with logistic regression and adjusted (adj) for confounders to determine the risk of complications/events. Results are presented as odds ratios (OR, [95% confidence interval]). MAIN RESULTS Midline insertion depth depended on body mass index, sex, and spinal level. After adjusting for confounders increased puncture depth (cm) remained an independent risk factor for vascular puncture (adjOR 1.27 [1.09-1.47], p = 0.002) and multiple skin punctures (adjOR 1.25 [1.21-1.29], p < 0.001). In contrast, dural punctures occurred at significantly shallower depths (adjOR 0.73 [0.60-0.89], p = 0.002). Paraesthesia was unrelated to insertion depth. Body mass index and sex had no influence on paraesthesia, dural and vascular punctures. Thoracic epidural insertion was associated with a lower risk of vascular puncture than at lumbar sites (adjOR 0.39 [0.18-0.84], p = 0.02). CONCLUSION Variation in midline insertion depth is an independent risk factor for epidural complications; however, variability precludes use of depth as a reliable guide to insertion in individual patients.

Abstract
BACKGROUND In general, late side effects after salvage radiotherapy (RT) for prostate cancer are below 10%. Patients with impaired DNA repair ability and genetic instability can have significantly increased reactions after RT. CASE, CLINICAL FOLLOW-UP, AND EXAMINATION We present a patient who experienced severe side effects after additive RT for prostate cancer and died from the complications 25 months after RT. Imaging (MR) is shown as well as three-color fluorescence in situ hybridization. The blood sample testing revealed that radiosensitivity was increased by 35-55%. We undertook a review of the literature to give an overview over the tests established that are currently considered useful. CONCLUSION This case highlights that the identification of patients with increased radiosensitivity is an important task in radiation protection. Groups of patients who should be screened have to be found and corresponding research facilities have to be set up.

Abstract
Cardiovascular diseases are one of the leading causes of morbidity and mortality in Germany. In these patients, the high-risk profile necessitates an interdisciplinary and multimodal approach to treatment. Endovascular interventions and vascular surgery have become established as an important element of this strategy in the past; however, the different anatomical localizations of pathological vascular alterations make it necessary to use a wide spectrum of procedural options and methods; therefore, the requirements for management of anesthesia are variable and necessitate a differentiated approach. Endovascular procedures can be carried out with the patient under general or regional anesthesia (RA); however, in the currently available literature there is no evidence for an advantage of RA over general anesthesia regarding morbidity and mortality, although a reduction in pulmonary complications could be found for some endovascular interventions. Epidural and spinal RA procedures should be carefully considered with respect to the risk-benefit ratio and consideration of the recent guidelines on anesthesia against the background of the current study situation and the regular use of therapy with anticoagulants. The following article elucidates the specific characteristics of anesthesia management as exemplified by some selected endovascular interventions.

Abstract
BACKGROUND Catheter-related infections are a serious complication of continuous thoracic epidural analgesia. Tunnelling catheters subcutaneously may reduce infection risk. We thus tested the hypothesis that tunnelling of thoracic epidural catheters is associated with a lower risk of catheter-related infections. METHODS Twenty-two thousand, four hundred and eleven surgical patients with continuous thoracic epidural analgesia included in the German Network for Regional Anaesthesia registry between 2007 and 2014 were grouped by whether their catheters were tunnelled (n=12 870) or not (n=9541). Catheter-related infections in each group were compared with Student's unpaired t and χ(2) tests. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated with logistic regression, adjusting for potential confounding factors, including age, ASA physical status score, use of catheter for ≥4 days, multiple skin puncture, hospital, and surgical department. RESULTS There were fewer catheter-related infections in patients with tunnelled catheters (4.5 vs 5.5%, P<0.001). Mild infections were also less common (4.0 vs 4.6%, P=0.009), as were moderate infections (0.4 vs 0.8%, P<0.001). After adjustment for potential confounding factors, tunnelling remained an independent prevention for any grade of infection (adjusted OR 0.51, 95% CI 0.42-0.61, P<0.001) and for mild infections (adjusted OR 0.54, 95% CI 0.43-0.66, P<0.001) and moderate and severe infections (adjusted OR 0.44, 95% CI 0.28-0.70, P=0.001). CONCLUSION Tunnelling was associated with a lower risk of thoracic epidural catheter-related infections.

Abstract
Introduction The therapeutic value of intravenous immunoglobulin (IVIG) as an adjuvant therapy in sepsis remains debatable. We hypothesized that intravenous administration of BT086, a predominantly IgM IVIG solution, would improve host defense in an established rabbit model of endotoxemia and systemic sepsis. Methods New Zealand white rabbits were randomized into the following four groups: (1) the negative control group without lipopolysaccharide (LPS, control), (2) the positive control group with LPS infusion (LPS group), (3) the albumin‐treated LPS group (ALB+LPS group), and (4) the BT086‐treated LPS group (BT086 + LPS group). A standardized amount of E. coli was intravenously injected into all of the animals. The vital parameters, the concentration of E. coli in the blood and other organs, the residual granulocyte phagocytosis activity, and the levels of the inflammatory mediators were measured. Histological changes in the lung and liver tissue were examined following autopsy. Results The elimination of E. coli from the bloodstream was expedited in the BT086‐treated group compared with the LPS‐ and albumin‐treated groups. The BT086 + LPS group exhibited higher phagocytic activity of polymorphonuclear neutrophils (PMNs) than the control and ALB+LPS groups. The liver energy stores were higher in the BT086 + LPS group than in the other groups. Conclusion Our data suggest that the IgM‐enriched IVIG has the potential to improve host defense in a rabbit model of endotoxemia. Studies using different animal models and dosages are necessary to further explore the potential benefits of IgM‐enriched IVIG solutions.

Abstract
BACKGROUND Patients with a chronic rhinosinusitis (CRS) and a concurrent deformity of the outer nose often require a septorhinoplasty (SRP) for functional or aesthetic reasons, combined with functional endoscopic sinus surgery (FESS). Aim of this study was to rule out the benefit of this combined approach. PATIENTS AND METHODS In a prospective study of 55 patients (30 m, 25 f, age 16-77 years) with a chronic rhinosinusitis with or without polyps combined with a deformity of the outer nose we performed a FESS together with a SRP using a closed or open approach. The control group included 55 patients (18 m, 37 w, age 18-62 years) with SRP alone. All patients got the same type of anestesia and an antibiotic prophylaxis with clindamycin. We compared the rates of inflammation and other complications of surgery. RESULTS The only difference between study group and control group was the period of time for surgery. There was neither a relevant inflammation in both groups nor any other significant complication (bleeding, edema, etc). Also the rate of minor revisions after SRP was almost the same in both groups. CONCLUSIONS The combined FESS and SRP is a safe and effective method without an increased risk of complications compared with SRP alone.

Abstract
BACKGROUND Obesity is believed to increase the risk of surgical site infections and possibly increase the risk of catheter-related infections in regional anesthesia. We, therefore, analyzed the influence of obesity on catheter-related infections defined within a national registry for regional anesthesia. METHODS The German Network for Regional Anesthesia database with 25 participating clinical centers was analyzed between 2007 and 2012. Exactly, 28,249 cases (13,239 peripheral nerve and 15,010 neuraxial blocks) of patients ≥ 14 years were grouped in I: underweight (BMI 13.2-18.49 kg/m(2) , n = 597), II: normal weight (BMI 18.5-24.9 kg/m(2) , n = 9272), III: overweight (BMI 25.0-29.9 kg/m(2) , n = 10,632), and IV: obese (BMI 30.0-70.3 kg/m(2) , n = 7,744). The analysis focused on peripheral and neuraxial catheter-related infections. Differences between the groups were tested with non-parametric ANOVA and chi-square (P < 0.05). Binary logistic regression was used to compare obese, overweight, or underweight patients with normal weight patients. Odds ratios (OR and 95% confidence interval) were calculated and adjusted for potential confounders. RESULTS Confounders with significant influence on the risk for catheter-related infections were gender, age, ASA score, diabetes, preoperative infection, multiple skin puncture, and prolonged catheter use. The incidence (normal weight: 2.1%, obese: 3.6%; P < 0.001) and the risk of peripheral catheter-related infection was increased in obese compared to normal weight patients [adjusted OR: 1.69 (1.25-2.28); P < 0.001]. In neuraxial sites, the incidence of catheter-related infections differed significantly between normal weight and obese patients (normal weight: 3.2%, obese: 2.3%; P = 0.01), whereas the risk was comparable [adjusted OR: 0.95 (0.71-1.28); P = 0.92]. CONCLUSION This retrospective cohort study suggests that obesity is an independent risk factor for peripheral, but not neuraxial, catheter-related infections.

Abstract
Despite high sequence similarity between NOP (nociceptin/orphanin FQ opioid peptide) and opioid receptors, marked differences in endogenous ligand selectivity, signal transduction, phosphorylation, desensitization, internalization and trafficking have been identified; underscoring the evolutionary difference between NOP and opioid receptors. Activation of NOP receptors affects nociceptive transmission in a site-specific manner, with antinociceptive effects prevailing after peripheral and spinal activation, and pronociceptive effects after supraspinal activation in rodents. The net effect of systemically administered NOP receptor agonists on nociception is proposed to depend on the relative contribution of peripheral, spinal and supraspinal activation, and this may depend on experimental conditions. Functional expression and regulation of NOP receptors at peripheral and central sites of the nociceptive pathway exhibits a high degree of plasticity under conditions of neuropathic and inflammatory pain. In rodents, systemically administered NOP receptor agonists exerted antihypersensitive effects in models of neuropathic and inflammatory pain. However, they were largely ineffective in acute pain while concomitantly evoking severe motor side effects. In contrast, systemic administration of NOP receptor agonists to non-human primates (NHPs) exerted potent and efficacious antinociception in the absence of motor and sedative side effects. The reason for this species difference with respect to antinociceptive efficacy and tolerability is not clear. Moreover, co-activation of NOP and μ-opioid peptide (MOP) receptors synergistically produced antinociception in NHPs. Hence, both selective NOP receptor as well as NOP/MOP receptor agonists may hold potential for clinical use as analgesics effective in conditions of acute and chronic pain.

Abstract
By reaction of (n-Bu4N)2[B12H12] with 2,2′-bipyridine at 190 °C the 2,2′-bipyridyl-undecahydro- closo-dodecaborate anion [(2,2′-C10H8N2)B12H11]− is formed which can be seperated from excess [B12H12]2− by ion exchange chromatography on diethylaminoethyl (DEAE) cellulose. The X-ray structure determination of (Ph4As)[(2, 2′-C10H8N2)B12H11] (monoclinic, space group P21/c with a = 13.3190(9), b = 10.1532(14), c = 28.788(3′) Å, β = 96.761(7)°, Z = 4) reveals that the bipyridyl substituent is bonded via one nitrogen atom. The 11B NMR spectrum exhibits a 1:5:5:1 pattern with ipso-B1 at -0.3, B2-B6 at -14.5, B7-B11 at -15.3 and antipodal-B12 at -15.9 ppm. The 13C and 1H NMR spectra show the characteristic patterns of the bipyridyl group in the range of 124.5 to 158.6 (13C) and 7.4 to 9.6 ppm (1H) respectively. The IR and Raman spectra exhibit characteristic BH stretching vibrations between 2445 and 2568 cm-1 and the stretching of the CC and CN bonds in the range of 1427 to 1619 cm-1 .

Abstract
Abstract
Purpose: Trastuzumab (T; Roche) is part of the standard treatment in patients (pts) of any age with early stage, HER2+ breast cancer, in addition to (neo)adjuvant chemotherapy (CT) and locoregional treatment. After its registration in Germany in 2006, this prospective observation study was started in order to assess the generalizability of the results from the randomized studies, specifically with respect to elderly age cohorts.
Methods: 4027 pts were enrolled between 2006 and 2012. 87 were non-eligible due to M1 and/or negative HER2 status. There were no restrictions for recruitment with respect to age or concomitant/sequential adjuvant medication. The long-term relapse/survival status of pts was retrieved by fax forms collected once a year. Safety assessment was limited to the treatment period. Data base cut-off was May 2013.
Results: Among the 3940 evaluable pts, there were 1013 elderly pts (EP) ≥ 65 years (y) of age (26%). This contrasts to the pivotal studies, e.g. with a proportion of only 6% beyond 65 y in the NSABP B-31 and NCCTG N9831 studies. The rate of EP steadily increased during the period from 2006 to 2009, remaining stable thereafter. More than half of the pts had pT≥2, with EP more often presenting with a larger tumor (56% vs. 48%,p<.0001). 52% had a grade 3 tumor. Hormone receptor positivity was recorded in 63%. As to be expected, performance status was more impaired in elderly compared to younger pts (ECOG 0: 53 vs 65%,p<.0001). 94% received CT, 78% as adjuvant, 14% as neoadjuvant treatment (in EP only 8%), while 2% received both modalities. In the vast majority (87%), T was administered sequentially to CT, with no differences among the age cohorts. The proportion without any adjuvant CT was higher in EP (8 vs. 5%). 56% of pts were treated with adjuvant endocrine medication, 78% with irradiation. T treatment was stopped prematurely in only 9% of pts, but more often in EP (11% vs 8%, p = .014).
After a follow-up period of up to a maximum of 8 y, 370 relapses were reported so far. The estimated recurrence-free survival is 94.7% (95% CI: 94-96%), 89.8% (89-91%), and 82.9% (81-85%) after 2, 3 and 5 y, respectively. Numeric results in EP are only slightly lower with 93.9 (92-96%), 89.3% (87-92%), and 81.6% (78-85%), not statistically significant (p = 0.18, HR = 1.17 [95% CI: 0.93 - 1.47]). Adverse effects with respect to cardiac function were reported in overall 153 pts (3.9%), with the majority of these cases of NCI grade 1 (39%) or 2 (38%). 23% of these events were of grade 3/4, but life-threatening in only 2 pts. Thus, the overall incidence of acute grade 3/4 cardiac function toxicity was 0.9%. In the EP subgroup the incidence across all NCI grades was only slightly increased (4.6%), but grade 3/4 cases were more common (1.6%).
Conclusion: Overall, the maturing follow-up data of this observational study confirm the beneficial results from the randomized studies. In addition, the data from more than thousand pts ≥ 65 y of age show that a similar anti-tumor efficiency can be achieved in elderly pts, and suggest that minor age-related differences detected with respect to adjuvant treatment duration, aggressiveness and toxicity do not impair the long-term clinical outcome.

Abstract
PURPOSE Mesenchymal tumours require high-dose radiation therapy (RT). Small bowel (SB) dose constraints have historically limited dose delivery to paraspinal and retroperitoneal targets. This retrospective study correlated SB dose-volume histograms with side-effects after proton radiation therapy (PT). PATIENTS AND METHODS Between 1997 and 2008, 31 patients (mean age 52.1 years) underwent spot scanning-based PT for paraspinal/retroperitoneal chordomas (81%), sarcomas (16%) and meningiom (3%). Mean total prescribed dose was 72.3 Gy (relative biologic effectiveness, RBE) delivered in 1.8-2 Gy (RBE) fractions. Mean follow-up was 3.8 years. Based on the pretreatment planning CT, SB dose distributions were reanalysed. RESULTS Planning target volume (PTV) was defined as gross tumour volume (GTV) plus 5-7 mm margins. Mean PTV was 560.22 cm(3). A mean of 93.2% of the PTV was covered by at least 90% of the prescribed dose. SB volumes (cm(3)) receiving doses of 5, 20, 30, 40, 50, 60, 70, 75 and 80 Gy (RBE) were calculated to give V5, V20, V30, V40, V50, V60, V70, V75 and V80 respectively. In 7/31 patients, PT was accomplished without any significant SB irradiation (V5=0). In 24/31 patients, mean maximum dose (Dmax) to SB was 64.1 Gy (RBE). Despite target doses of >70 Gy (RBE), SB received >50 and >60 Gy (RBE) in only 61 and 54% of patients, respectively. Mean SB volumes (cm(3)) covered by different dose levels (Gy, RBE) were: V20 (n=24): 45.1, V50 (n=19): 17.7, V60 (n=17): 7.6 and V70 (n=12): 2.4. No acute toxicity ≥ grade 2 or late SB sequelae were observed. CONCLUSION Small noncircumferential volumes of SB tolerated doses in excess of 60 Gy (RBE) without any clinically-significant late adverse effects. This small retrospective study has limited statistical power but encourages further efforts with higher patient numbers to define and establish high-dose threshold models for SB toxicity in modern radiation oncology.

Abstract
Abstract
Metalworking fluids (MWF) are used routinely throughout the world as cooling and lubricating agent for metal-cutting processes. They are important components to maintain the quality and precision of the metal-cutting but are slowly consumed within this process. Hence, monitoring of ageing of the MWFs before depletion is important for economical, ecological and security reasons. A method is presented, which enables to estimate the ageing of tools by measuring the microbial volatile outcome (MVOC) of the MWF. Measurements are done by headspace sorptive extraction combined to thermal desorption in a gas chromatography setup with mass selective detector (HSSE-TDS-GCMS). It could be shown that ageing of tools correlates to emission of ketonic and alcoholic MVOCs (namely 2-Heptanone, 2-Octanone, 1-Octanol, 2-Nonanone and 2-Decanone). Analysis of these components can be used as “ageing marker” for the investigated MWF solutions. The obtained information can further be used to calibrate electronic nose sensors for high-throughput and rapid analysis in future projects. Hence, it can be concluded that headspace analysis of volatile microbial metabolites by HSSE in combination with TDS-GC-MS is a suitable monitoring technique for the ageing of metalworking fluids.

Abstract
BACKGROUND Endoscopic sinus surgery usually requires a move of the middle nasal turbinate into the midline to achieve a better sight into the ethmoidal sinuses. In this procedure damages of the turbinate are possible, which later can lead to a scarred fixation of the turbinate. Fixing of the turbinate to the septum can avoid this effect, but could reduce smell ability by blocking of the upper nasal duct. MATERIAL In a prospective study with 83 patients with chronic sinusitis (55% CRS with polyps, 45% CRS without polyps) at the end of the operation the middle nasal turbinates were fixed at the nasal septum with a 4 × 0 stitch. Before the operation and 6 weeks, 3 and 5 months after operation the smell was tested using the "sniffin'sticks" threshold test. RESULTS After operation the ethmoidal area remained open without developing of relevant synechiae or scars. The smell ability decreased after surgery due to the obstruction of the upper nasal duct, but improved again later. After 5 months the average threshold of smell was better than before operation. Testing of the threshold values with the t-test showed a significant difference (p<0.001) between the pre- and postoperative status. CONCLUSION The method of medialization and temporary septal fixation of the middle nasal turbinate allows a sufficient ventilation and drainage of the paranasal sinuses after sinus surgery. Due to only temporary fixation of the turbinate at the septum, a permanent obstruction of the upper nasal duct and the olfactory area is prevented. Thus the threshold of smell is not reduced.

Abstract
BACKGROUND A recent review of studies of case management in dementia argues that lack of evidence of cost-effectiveness should discourage the use of this approach to care. We argue that that this is too conservative a stance, given the urgent need throughout the world to improve the quality of care for people with dementia and their caregivers. We propose a research agenda on case management for people with dementia. METHOD A critical comparison was made of the studies identified in two systematic reviews of trials of case management for dementia, with selective inclusion of non-trial studies and economic evaluations. RESULTS Our interpretation of the literature leads us to four provisional conclusions. First, studies with long follow-up periods tend to show delayed relocation of people with dementia to care homes. Second, the quality of life of people with dementia and their caregivers may also influence the likelihood of relocation. Third, different understandings of what constitutes case management make interpretation of studies difficult. Fourth, we agree that the population most likely to benefit from case management needs to be characterised. Earlier intervention may be more beneficial than intervening when the condition has progressed and the individual's situation is highly complex. However, this runs counter to some definitions of case management as an administrative, professional, and systemic focus on people with high needs and where expensive support is accessed or in prospect. CONCLUSIONS More work needs to be carried out in a more focused way in order to establish the value of case management for people with dementia. Since care home residence is such a sizeable contributor to the costs of dementia care, studies need to be long enough to capture possible postponed relocation. However, case management studies with shorter follow-up periods can still contribute to our understanding, since they can demonstrate improved quality of life. Future research should be built around a common, agreed definition of types of case management.

Abstract
We investigated the effects of targeting the mitotic regulators aurora kinase A and B in pediatric acute lymphoblastic leukemia (ALL) and acute myeloid leukemia (AML). Aurora protein expression levels in pediatric ALL and AML patient samples were determined by western blot and reverse phase protein array. Both kinases were overexpressed in ALL and AML patients (P<0.0002), especially in E2A-PBX1-translocated ALL cases (P<0.002), compared with normal bone-marrow mononuclear cells. Aurora kinase expression was silenced in leukemic cell lines using short hairpin RNAs and locked nucleic acid-based mRNA antagonists. Aurora B knockdown resulted in proliferation arrest and apoptosis, whereas aurora A knockdown caused no or only minor growth delay. Most tested cell lines were highly sensitive to the AURKB-selective inhibitor barasertib–hydroxyquinazoline–pyrazol–anilide (AZD1152-HQPA) in the nanomolar range, as tested with an MTS (3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium) assay. But most importantly, primary ALL cells with a high aurora B protein expression, especially E2A-PBX1-positive cases, were sensitive as well. In adult AML early clinical trials, clear responses are observed with barasertib. Here we show that inhibition of aurora B, more than aurora A, has an antiproliferative and pro-apoptotic effect on acute leukemia cells, indicating that particularly targeting aurora B may offer a new strategy to treat pediatric ALL and AML.
