These ideally should be sensitive and selective while being easy to understand and adjust. We propose here the MTL30 quality indicator which takes into account 30-day mortality, transfer within 30 days, and a length of stay of 30 days as composite markers of an uneventful operative/postoperative course. Methods Patients documented in the StuDoQ|Colon and StuDoQ|Rectal carcinoma register of the German Society for General and Visceral Surgery (DGAV) were analyzed with regard to the effects of patient and tumor-related risk factors as well as postoperative complications on the MTL30. Results In univariate analysis, the MTL30 correlated significantly with patient and tumor-related risk factors such as ASA score (p<0.001), age (p<0.001), or UICC stage (p<0.001). There was a high sensitivity for the postoperative occurrence of complications such as re-operations (p<0.001) or subsequent bleeding (p<0.001), as well as a significant correlation with the CDC classification (p<0.001). In multivariate analysis, patient-related risk factors and postoperative complications significantly increased the odds ratio for a positive MTL30. A negative MTL30 showed a high specify for an uneventful operative and postoperative course. Conclusion The MTL30 is a valid indicator of colorectal surgical quality.

We report the first 2 years' experience of implementing a comprehensive telemedical stroke network comprising all levels of stroke care in a defined region. Methods The TRANSIT-Stroke network covers a mainly rural region in north-western Bavaria (Germany). All hospitals providing acute stroke care in this region participate in TRANSIT-Stroke, including four hospitals with a supra-regional certified stroke unit (SU) care (level III), three of those providing teleconsultation to two hospitals with a regional certified SU (level II) and five hospitals without specialized SU care (level I). For a two-year-period (01/2015 to 12/2016), data of eight of these hospitals were available; 13 evidence-based quality indicators (QIs) related to processes during hospitalisation were evaluated quarterly and compared according to predefined target values between level-I- and level-II/III-hospitals. Results Overall, 7881 patients were included (mean age 74.6 years +/- 12.8; 48.4% female). In level-II/III-hospitals adherence of all QIs to predefined targets was high ab initio. In level-I-hospitals, three patterns of QI-development were observed: a) high adherence ab initio (31%), mainly in secondary stroke prevention; b) improvement over time (44%), predominantly related to stroke specific diagnosis and in-hospital organization; c) no clear time trends (25%). Overall, 10 out of 13 QIs reached predefined target values of quality of care at the end of the observation period. Conclusion The implementation of the comprehensive TRANSIT-Stroke network resulted in an improvement of quality of care in level-I-hospitals.

T1 - Trajectories of Left Ventricular Ejection Fraction After Acute Decompensation for Systolic Heart Failure: Concomitant Echocardiographic and Systemic Changes, Predictors, and Impact on Clinical Outcomes JF - Journal of the American Heart Association N2 - Prospective longitudinal follow‐up of left ventricular ejection fraction (LVEF) trajectories after acute cardiac decompensation of heart failure is lacking. We investigated changes in LVEF and covariates at 6‐months' follow‐up in patients with a predischarge LVEF ≤40%, and determined predictors and prognostic implications of LVEF changes through 18‐months' follow‐up. Methods and Results Interdisciplinary Network Heart Failure program participants (n=633) were categorized into subgroups based on LVEF at 6‐months' follow‐up: normalized LVEF (>50%; heart failure with normalized ejection fraction, n=147); midrange LVEF (41%–50%; heart failure with midrange ejection fraction, n=195), or persistently reduced LVEF (≤40%; heart failure with persistently reduced LVEF , n=291). All received guideline‐directed medical therapies. At 6‐months' follow‐up, compared with patients with heart failure with persistently reduced LVEF, heart failure with normalized LVEF or heart failure with midrange LVEF subgroups showed greater reductions in LV end‐diastolic/end‐systolic diameters (both P<0.001), and left atrial systolic diameter (P=0.002), more increased septal/posterior end‐diastolic wall‐thickness (both P<0.001), and significantly greater improvement in diastolic function, biomarkers, symptoms, and health status. Heart failure duration <1 year, female sex, higher predischarge blood pressure, and baseline LVEF were independent predictors of LVEF improvement. Mortality and event‐free survival rates were lower in patients with heart failure with normalized LVEF (P=0.002). Overall, LVEF increased further at 18‐months' follow‐up (P<0.001), while LV end‐diastolic diameter decreased (P=0.048). However, LVEF worsened (P=0.002) and LV end‐diastolic diameter increased (P=0.047) in patients with heart failure with normalized LVEF hospitalized between 6‐months' follow‐up and 18‐months' follow‐up. Conclusions Six‐month survivors of acute cardiac decompensation for systolic heart failure showed variable LVEF trajectories, with >50% showing improvements by ≥1 LVEF category. LVEF changes correlated with various parameters, suggesting multilevel reverse remodeling, were predictable from several baseline characteristics, and were associated with clinical outcomes at 18‐months' follow‐up. Repeat hospitalizations were associated with attenuation of reverse remodeling."

A. A1 - Heuschmann, Peter U. T1 - Temporal changes in the quality of acute stroke care in five national audits across Europe JF - BioMed Research International N2 - Background. Data on potential variations in delivery of appropriate stroke care over time are scarce. We investigated temporal changes in the quality of acute hospital stroke care across five national audits in Europe over a period of six years. Methods. Data were derived from national stroke audits in Germany, Poland, Scotland, Sweden, and England/Wales/Northern Ireland participating within the European Implementation Score (EIS) collaboration. Temporal changes in predefined quality indicators with comparable information between the audits were investigated. Multivariable logistic regression analyses were performed to estimate adherence to quality indicators over time. Results. Between 2004 and 2009, individual data from 542,112 patients treated in 538 centers participating continuously over the study period were included. In most audits, the proportions of patients who were treated on a SU, were screened for dysphagia, and received thrombolytic treatment increased over time and ranged from 2-fold to almost 4-fold increase in patients receiving thrombolytic therapy in 2009 compared to 2004. Conclusions. A general trend towards a better quality of stroke care defined by standardized quality indicators was observed over time. The association between introducing a specific measure and higher adherence over time might indicate that monitoring of stroke care performance contributes to improving quality of care.

Anastomotic leakage is a leading cause of morbidity and death after resection for CRC. The aim of this study was to assess the rate of anastomosis creation, the risk of anastomotic leakage and death in surgery for left-sided CRC in elderly patients. Methods This prospective cohort study compared patients less than 80 and 80 or more years with left-sided CRC resection performed between 2013 and 2019. Data were provided from a risk-adjusted surgical quality-assessment system with 219 participating centres in Germany. Outcome measures were the rate of anastomoses, anastomotic leakages, death at 30 days and 2-year overall survival (OS). Propensity score matching was used to control for selection bias and compare subgroups of patients of less than 80 and 80 or more years. Results Out of 18 959 patients, some 3169 (16.7 per cent) were octogenarians. Octogenarians were less likely to receive anastomoses (82.0 versus 92.9 per cent, P < 0.001; odds ratio 0.50 (95 per cent c.i. 0.44 to 0.58), P < 0.001). The rate of anastomotic leakages did not differ between age groups (8.6 versus 9.7 per cent, P = 0.084), but 30-day mortality rate after leakage was significantly higher in octogenarians (15.8 versus 3.5 per cent, P < 0.001). Overall, anastomotic leakage was the strongest predictor for death (odds ratio 4.95 (95 per cent c.i. 3.66 to 6.66), P < 0.001). In the subgroup with no leakage, octogenarians had a lower 2-year OS rate than younger patients (71 versus 87 per cent, P < 0.001), and in the population with anastomotic leakage, the 2-year OS was 80 per cent in younger and 43 per cent in elderly patients (P < 0.001). After propensity score matching, older age remained predictive for not receiving an anastomosis (odds ratio 0.54 (95 per cent c.i. 0.46 to 0.63), P < 0.001) and for death (odds ratio 2.60 (95 per cent c.i. 1.78 to 3.84), P < 0.001), but not for the occurrence of leakages (odds ratio 0.94 (95 per cent c.i. 0.76 to 1.15), P = 0.524). Conclusion Anastomotic leakage is not more common in octogenarians, but an age of 80 years or older is an independent factor for not receiving an anastomosis in surgery for left-sided CRC. The mortality rate in the case of leakage in octogenarians was reported to exceed 15 per cent.

Hierzu wurden die Daten von 135 Patienten, die sich von Mai bis einschließlich September 2002 einer Herzoperation (Bypass-, Herzklappen-, oder Kombinations-Operation) an der Klinik für Herz- und Thorax-Chirurgie der Universität Würzburg unterzogen, nachuntersucht. Da nur 3/6 der Risiko-Scores eine Aussage bezüglich der postoperativen Morbidität treffen, wurden die, die Morbidität betreffenden Daten keiner statistischen Analyse zugeführt. 3/135 Patienten verstarben perioperativ (2,2%). 74/135 Patienten entwickelten postoperativ Komplikationen (54,8%). Die Analyse der Daten zeigte für keinen der Risiko-Scores statistische Signifikanz (p ≤ 0,05). Der Euro-Score war der einzige Risiko-Score, der alle verstorbenen Patienten in die Gruppe mit dem höchsten Risiko eingeteilt hatte. Aufgrund seiner vielen Parameter und wenigen Punkte pro Parameter ist der Euro-Score für zufällige Ereignisse und Fehleinteilungen weniger anfällig als andere Risiko-Scores. Die Mortalität als Endpunkt ist für einen Risiko-Score besser geeignet als die Morbidität, da kein Raum für subjektive Auslegung und Fehleinschätzung besteht. Aufgrund der Schwierigkeit gemeinsame prädiktive Parameter für Mortalität und Morbidität zu finden sollten getrennte Score-Systeme zur Anwendung kommen. Jeder Risiko-Score sollte von Zeit zu Zeit überarbeitet und dem medizinischen Fortschritt angepasst werden, bei der Auswahl der Parameter ist auf ausreichende Objektivität und exakte Definition zu achten. N2 - The objective of this paper was the comparison of 6 score-systems for risk stratification considering perioperative mortality in cardiac surgery (Parsonnet-Score, Cleveland Clinic-Score, Ontario Province Risk-Score, French-Score, Pons-Score and Euro-Score). For that the data of 135 patients undergoing cardiac surgery (bypass-, heart valve-, or combined bypass/heart valve-operation) between May and September 2002 at the Clinic for Cardiac and Thoracic Surgery in Würzburg was collected. Only 3/6 risk-scores considered postoperative morbidity as well as mortality, so data concerning morbidity was collected but not statistically analyzed. 3/135 patients died perioperative (2.2%). 74/135 patients appearded to show postoperative complications (54.8%). Analysis showed no statistical significance (p ≤ 0.005) for any risk-score. Euro-Score was the only risk-score that had placed all deceased patients in the group with the highest risk. Due to its many parameters and low weigh of the single parameter Euro-Score is less susceptible to chance and wrong grouping of the single patient. Mortality as the final point of a risk-score seems to be more suited than morbidity, because there is no space for subjectivity. As it is difficult to identify common predictive parameters for mortality and morbidity different score-systems should be used. Every risk-score sould be revised sometimes in order to adjust it to the progress of medical development.

Here, we assessed the potential association of sclerostin with the development of coronary artery (CAC) and aortic valve calcifications (AVC) in haemodialysis (HD) patients. Methods: We conducted a cross-sectional multi-slice computed tomography (MS-CT) scanning study in 67 chronic HD patients (59.4 +/- 14.8 yrs) for measurement of CAC and AVC. We tested established biomarkers as well as serum sclerostin (ELISA) regarding their association to the presence of calcification. Fifty-four adults without relevant renal disease served as controls for serum sclerostin levels. Additionally, sclerostin expression in explanted aortic valves from 15 dialysis patients was analysed ex vivo by immunohistochemistry and mRNA quantification (Qt-RT-PCR). Results: CAC (Agatston score > 100) and any AVC were present in 65% and in 40% of the MS-CT patient group, respectively. Serum sclerostin levels (1.53 +/- 0.81 vs 0.76 +/- 0.31 ng/mL, p < 0.001) were significantly elevated in HD compared to controls and more so in HD patients with AVC versus those without AVC (1.78 +/- 0.84 vs 1.35 +/- 0.73 ng/mL, p = 0.02). Multivariable regression analysis for AVC revealed significant associations with higher serum sclerostin. Ex vivo analysis of uraemic calcified aortic valves (n = 10) revealed a strong sclerostin expression very close to calcified regions (no sclerostin staining in non-calcified valves). Correspondingly, we observed a highly significant upregulation of sclerostin mRNA in calcified valves compared to non-calcified control valves. Conclusion: We found a strong association of sclerostin with calcifying aortic heart valve disease in haemodialysis patients. Sclerostin is locally produced in aortic valve tissue adjacent to areas of calcification.

This study explored GH secretion, as well as hormonal, clinical, neuroradiological, metabolic, and comorbid profile in a cohort of 40 acromegalic patients considered cured on the basis of the previous guidelines after a mean follow-up period of 17.2 years from remission, in order to assess the impact of the current criteria. At the last follow-up visit, in the presence of normal IGF-I concentrations, postglucose GH nadir was over 0.4 mu g/L in 11 patients (Group A) and below 0.4 mu g/L in 29 patients (Group B); moreover, Group A showed higher basal GH levels than Group B, whereas a significant decline of both GH and postglucose GH nadir levels during the follow-up was observed in Group B only. No differences in other evaluated parameters were found. These results seem to suggest that acromegalic patients considered cured on the basis of previous guidelines do not need a more intensive monitoring than patients who met the current criteria of disease control, supporting instead that the cut-off of 0.4 mcg/L might be too low for the currently used GH assay.

Currently there is little data on the effect of screening for depression and anxiety on the quality of life and the prognosis of heart failure (HF). We will investigate the association between the recognition of current depression/anxiety by the general practitioner (GP) and the quality of life and the patients' prognosis. Methods/Design: In this multicenter, prospective, observational study 3,950 patients with HF are recruited by general practices in Germany. The patients fill out questionnaires at baseline and 12-month follow-up. At baseline the GPs are interviewed regarding the somatic and psychological comorbidities of their patients. During the follow-up assessment, data on hospitalization and mortality are provided by the general practice. Based on baseline data, the patients are allocated into three observation groups: HF patients with depression and/or anxiety recognized by their GP (P+/+), those with depression and/or anxiety not recognized (P+/-) and patients without depression and/or anxiety (P-/-). We will perform multivariate regression models to investigate the influence of the recognition of depression and/or anxiety on quality of life at 12 month follow-up, as well as its influences on the prognosis (hospital admission, mortality). Discussion: We will display the frequency of GP-acknowledged depression and anxiety and the frequency of installed therapeutic strategies. We will also describe the frequency of depression and anxiety missed by the GP and the resulting treatment gap. Effects of correctly acknowledged and missed depression/anxiety on outcome, also in comparison to the outcome of subjects without depression/anxiety will be addressed. In case results suggest a treatment gap of depression/anxiety in patients with HF, the results of this study will provide methodological advice for the efficient planning of further interventional research.

T1 - Prevalence and prognostic impact of chronic kidney disease and anaemia across ACC/AHA precursor and symptomatic heart failure stages JF - Clinical Research in Cardiology N2 - Background The importance of chronic kidney disease (CKD) and anaemia has not been comprehensively studied in asymptomatic patients at risk for heart failure (HF) versus those with symptomatic HF. We analysed the prevalence, characteristics and prognostic impact of both conditions across American College of Cardiology/American Heart Association (ACC/AHA) precursor and HF stages A–D. Methods and results 2496 participants from three non-pharmacological German Competence Network HF studies were categorized by ACC/AHA stage; stage C patients were subdivided into C1 and C2 (corresponding to NYHA classes I/II and III, respectively). Overall, patient distribution was 8.1%/35.3%/32.9% and 23.7% in ACC/AHA stages A/B/C1 and C2/D, respectively. These subgroups were stratified by the absence ( – ) or presence ( +) of CKD (estimated glomerular filtration rate [eGFR] < 60 mL/min/1.73m2) and anaemia (haemoglobin in women/men < 12/ < 13 g/dL). The primary outcome was all-cause mortality at 5-year follow-up. Prevalence increased across stages A/B/C1 and C2/D (CKD: 22.3%/23.6%/31.6%/54.7%; anaemia: 3.0%/7.9%/21.7%/33.2%, respectively), with concordant decreases in median eGFR and haemoglobin (all p < 0.001). Across all stages, hazard ratios [95% confidence intervals] for all-cause mortality were 2.1 [1.8–2.6] for CKD + , 1.7 [1.4–2.0] for anaemia, and 3.6 [2.9–4.6] for CKD + /anaemia + (all p < 0.001). Population attributable fractions (PAFs) for 5-year mortality related to CKD and/or anaemia were similar across stages A/B, C1 and C2/D (up to 33.4%, 30.8% and 34.7%, respectively). Conclusions Prevalence and severity of CKD and anaemia increased across ACC/AHA stages. Both conditions were individually and additively associated with increased 5-year mortality risk, with similar PAFs in asymptomatic patients and those with symptomatic HF.

Cross-sectional surveys are used to evaluate the implementation of such guidelines. The present survey investigated screening for glucose perturbations in people with coronary artery disease and compared patients with known and newly detected type 2 diabetes with those without diabetes in terms of their life-style and pharmacological risk factor management in relation to contemporary European guidelines. Methods: A total of 6187 patients (18-80 years) with coronary artery disease and known glycaemic status based on a self reported history of diabetes (previously known diabetes) or the results of an oral glucose tolerance test and HbA1c (no diabetes or newly diagnosed diabetes) were investigated in EUROASPIRE IV including patients in 24 European countries 2012-2013. The patients were interviewed and investigated in order to enable a comparison between their actual risk factor control with that recommended in current European management guidelines and the outcome in previously conducted surveys. Results: A total of 2846 (46 %) patients had no diabetes, 1158 (19 %) newly diagnosed diabetes and 2183 (35 %) previously known diabetes. The combined use of all four cardioprotective drugs in these groups was 53, 55 and 60 %, respectively. A blood pressure target of <140/90 mmHg was achieved in 68, 61, 54 % and a LDL-cholesterol target of <1.8 mmol/L in 16, 18 and 28 %. Patients with newly diagnosed and previously known diabetes reached an HbA1c <7.0 % (53 mmol/mol) in 95 and 53 % and 11 % of those with previously known diabetes had an HbA1c >9.0 % (>75 mmol/mol). Of the patients with diabetes 69 % reported on low physical activity. The proportion of patients participating in cardiac rehabilitation programmes was low (approximate to 40 %) and only 27 % of those with diabetes had attended diabetes schools. Compared with data from previous surveys the use of cardioprotective drugs had increased and more patients were achieving the risk factor treatment targets. Conclusions: Despite advances in patient management there is further potential to improve both the detection and management of patients with diabetes and coronary artery disease.

Erfasst wurden zum einen wichtige prä- und peripartale Faktoren, u.a. mütterliches Alter und Risiko,Schwangerschaftsalter, Indikation zur Schwangerschaftsbeendigung und Entbindungsmodus, und zum anderen fetale Outcome-Parameter wie Gewicht, Apgar Score, Nabelarterien-pH-Wert, Base Excess und Intubation. Darüber hinaus wurden für jedes Kind die Morbiditätsdiagnosen und bei gestorbenen Kindern die Todesursachen aufgenommen. In 37 % der Fälle lag der Frühgeburt ein vorzeitiger Blasensprung zugrunde, in 31 % eine vorzeitige Wehentätigkeit. Die übrigen 32 % wurden durch maternofetale Pathologie hervorgerufen. Das Gewicht der Frühgeborenen lag zu 75 % unter 1500 g. In einer schweren Azidose befanden sich 6 % der Kinder. Eine starke Abhängigkeit der Outcome-Parameter von Poleinstellung und Entbindungsmodus war nicht zu beobachten. Frühgeborene nach fetaler Entbindungsindikation wiesen ein schlechteres Outcome auf als nach maternaler Indikation. Von den beobachteten Krankheiten kam das Atemnotsyndrom am häufigsten vor (in 63 % der Fälle), bei 20 % der Kinder III.-IV. Grades. Hochgradige Retinopathie (Grade III-IV) wurde in 5,4 %, retrolentale Fibroplasie in 0,6 % der Fälle diagnostiziert. Ein Drittel der Kinder erkrankten an einer Sepsis. Bei 18 % entwickelte sich im Verlauf eine bronchopulmonale Dysplasie. Schwere Hirnblutungen (III.-IV. Grades) erlitten 4,5 % der Frühgeborenen, periventrikuläre Leukomalazie 3,6 % und nekrotisierende Enterokolitis 1,5 %. Die genannten Krankheiten traten mit zunehmendem Schwangerschaftsalter weniger häufig auf. Die Prognose verbesserte sich besonders stark in den SSW 28-30. 6 von 16 Todesfällen (38 %) entfielen auf die ersten 24 Lebensstunden. Die Todesursachen waren Unreife/Mangelgeburt (31 %), Sepsis (31 %), Fehlbildungen und intrauterine Asphyxie (jeweils 13 %). Die neonatale Mortalitätsrate nahm mit zunehmendem Geburtsgewicht deutlich ab: Von 33 % für Frühgeborene unter 500 g, auf 3 % ab 1000 g. Die mittlere Latenzperiode nach einem vorzeitigen Blasensprung betrug 9,1 Tage (in 90 % der Fälle bis zu 3 Wochen, Maximum: 10 Wochen). Kinder beider betrachteter Gruppen von 23-28 und 29-32 SSW profitierten vom angewendeten konservativen Management: Bezüglich der Lungenreife war eine klare Verbesserung zu beobachten, falls die RDS-Prophylaxe 48 Stunden vor der Geburt abgeschlossen war. Sepsis kam zwar in der Gruppe mit niedrigerem Gestationsalter häufiger vor, war jedoch nicht direkt abhängig von der Latenzperiode. Im Vergleich mit anderen aktuellen Studien lagen die in dieser Arbeit festgestellten Morbiditätsraten etwa gleichauf. Die Kinder des eigenen Kollektivs entwickelten aber seltener intraventrikuläre Hämorrhagie und periventrikuläre Leukomalazie. Die starke Abnahme von Morbidität und Mortalität mit zunehmendem Schwangerschaftsalter wird in den Vergleichsstudien ähnlich berichtet. Eine nicht vernachlässigbare Überlebenschance kann bereits ab 23 SSW gegeben sein (4 von 6 dieser Kinder überlebten die Neonatalperiode). Die Chancen auf ein gesundes Überleben jedoch steigen besonders in den SSW 28-30. Daher ist in den sehr frühen SSW die Prolongation der Schwangerschaft zu empfehlen.

T1 - Invasive fungal diseases in patients with new diagnosed acute lymphoblastic leukaemia JF - Mycoses N2 - Background Patients with acute leukaemia have a high incidence of fungal infections. This has primarily been shown in acute myeloid leukaemia and is different for acute lymphoblastic leukaemia. Until now no benefit of mould active prophylaxis has been demonstrated in the latter population. Methods In this retrospective single‐centre study, we analysed the incidence, clinical relevance, and outcome of invasive fungal diseases (IFD) as well as the impact of antifungal prophylaxis for the first 100 days following the primary diagnosis of acute lymphoblastic leukaemia. Results In 58 patients a high rate of proven, probable, and possible fungal infections could be demonstrated with a 3.4%, 8.6%, and 17.2% likelihood, respectively. The incidence might be even higher, as nearly 40% of all patients had no prolonged neutropenia for more than 10 days, excluding those from the European Organization of Research and Treatment of cancer and the Mycoses Study Group criteria for probable invasive fungal disease. The diagnosed fungal diseases had an impact on the duration of hospitalisation, which was 13 days longer for patients with proven/probable IFD compared to patients with no signs of fungal infection. Use of antifungal prophylaxis did not significantly affect the risk of fungal infection. Conclusion Patients with acute lymphoblastic leukaemia are at high risk of acquiring an invasive fungal disease. Appropriate criteria to define fungal infections, especially in this population, and strategies to reduce the risk of infection, including antifungal prophylaxis, need to be further evaluated.

We conducted a retrospective matched-pair analysis of data from a 10-year period from the multicenter database TraumaRegister DGU\(^®\) to analyze the impact of a concomitant femoral fracture on the outcome of TBI patients. A total of 4508 patients with moderate to critical TBI were included and matched by severity of TBI, American Society of Anesthesiologists (ASA) risk classification, initial Glasgow Coma Scale (GCS), age, and sex. Patients who suffered combined TBI and femoral fracture showed increased mortality and worse outcome at the time of discharge, a higher chance of multi-organ failure, and a rate of neurosurgical intervention. Especially those with moderate TBI showed enhanced in-hospital mortality when presenting with a concomitant femoral fracture (p = 0.037). The choice of fracture treatment (damage control orthopedics vs. early total care) did not impact mortality. In summary, patients with combined TBI and femoral fracture have higher mortality, more in-hospital complications, an increased need for neurosurgical intervention, and inferior outcome compared to patients with TBI solely. More investigations are needed to decipher the pathophysiological consequences of a long-bone fracture on the outcome after TBI.

T1 - High convection volume in online post-dilution haemodiafiltration: relevance, safety and costs JF - Clinical Kidney Journal N2 - Increasing evidence suggests that treatment with online post-dilution haemodiafiltration (HDF) improves clinical outcome in patients with end-stage kidney disease, if compared with haemodialysis (HD). Although the primary analyses of three large randomized controlled trials (RCTs) showed inconclusive results, post hoc analyses of these and previous observational studies comparing online post-dilution HDF with HD showed that the risk of overall and cardiovascular mortality is lowest in patients who are treated with high-volume HDF. As such, the magnitude of the convection volume seems crucial and can be considered as the ‘dose’ of HDF. In this narrative review, the relevance of high convection volume in online post-dilution HDF is discussed. In addition, we briefly touch upon some safety and cost issues.

Methods: Between January 2010 and June 2013, patients with a confirmed diagnosis of CHF were enrolled and randomly assigned to 2 study groups comprising usual care with and without an interactive bi-directional remote monitoring system (Motiva\(^{®}\)). The primary endpoint in CardioBBEAT is the Incremental Cost-Effectiveness Ratio (ICER) established by the groups' difference in total cost and in the combined clinical endpoint "days alive and not in hospital nor inpatient care per potential days in study" within the follow-up of 12 months. Results: A total of 621 predominantly male patients were enrolled, whereof 302 patients were assigned to the intervention group and 319 to the control group. Ischemic cardiomyopathy was the leading cause of heart failure. Despite randomization, subjects of the control group were more often in NYHA functional class III-IV, and exhibited peripheral edema and renal dysfunction more often. Additionally, the control and intervention groups differed in heart rhythm disorders. No differences existed regarding risk factor profile, comorbidities, echocardiographic parameters, especially left ventricular and diastolic diameter and ejection fraction, as well as functional test results, medication and quality of life. While the observed baseline differences may well be a play of chance, they are of clinical relevance. Therefore, the statistical analysis plan was extended to include adjusted analyses with respect to the baseline imbalances. Conclusions: CardioBBEAT provides prospective outcome data on both, clinical and health economic impact of home telemonitoring in CHF. The study differs by the use of a high evidence level randomized controlled trial (RCT) design along with actual cost data obtained from health insurance companies. Its results are conducive to informed political and economic decision-making with regard to home telemonitoring solutions as an option for health care. Overall, it contributes to developing advanced health economic evaluation instruments to be deployed within the specific context of the German Health Care System.

Because capacity for RT-PCR testing increased greatly in the early phase of the Covid-19 pandemic, R0 determinations based on these incidence values are subject to strong bias. We propose to use Covid-19-induced excess mortality to determine R0 regardless of RT-PCR testing capacity. We used data from the Robert Koch Institute (RKI) on the incidence of Covid cases, Covid-related deaths, number of RT-PCR tests performed, and excess mortality calculated from data from the Federal Statistical Office in Germany. We determined R0 using exponential growth estimates with a serial interval of 4.7 days. We used only datasets that were not yet under the influence of policy measures (e.g., lockdowns or school closures). The uncorrected R0 value for the spread of SARS-CoV-2 based on RT-PCR incidence data was 2.56 (95% CI 2.52–2.60) for Covid-19 cases and 2.03 (95% CI 1.96–2.10) for Covid-19-related deaths. However, because the number of RT-PCR tests increased by a growth factor of 1.381 during the same period, these R0 values must be corrected accordingly (R0corrected = R0uncorrected/1.381), yielding 1.86 for Covid-19 cases and 1.47 for Covid-19 deaths. The R0 value based on excess deaths was calculated to be 1.34 (95% CI 1.32–1.37). A sine-function-based adjustment for seasonal effects of 40% corresponds to a maximum value of R0January = 1.68 and a minimum value of R0July = 1.01. Our calculations show an R0 that is much lower than previously thought. This relatively low range of R0 fits very well with the observed seasonal pattern of infection across Europe in 2020 and 2021, including the emergence of more contagious escape variants such as delta or omicron. In general, our study shows that excess mortality can be used as a reliable surrogate to determine the R0 in pandemic situations.

Methoden: Es erfolgte eine post-hoc Analyse der 4D Studie, einer randomisierten, placebo-kontrollierten, multizentrischen Studie, die die Wirkung von Atorvastatin bei hämodialysepflichtigen Typ 2 Diabetikern untersucht hat. Vor Analyse der Daten wurden die Patienten je nach verordneten Dialysefiltern in Gruppen eingeteilt; entsprechend Permeabilität und Flux wurden high- und low-flux und entsprechend der Biokompatibilität wurden Cellulose-, semisynthetische und synthetische Dialysemembranen unterschieden. Von 1255 Patienten wurden 648 (52%) identifiziert, die kontinuierlich mit einer synthetischen (syn) high-flux (HFS) (n=214), einer low-flux (LFS) syn (n=247), einer semisynthetischen LF (LFSS) (n=119) oder einer LF Cellulose (LFC)-Membran (n=41) behandelt wurden. Die Endpunkte waren Gesamtmortalität und kombinierte kardiale Mortalität, bestehend aus nicht tödlichem Herzinfarkt, Apoplex und kardiovaskulärem Tod. Ergebnisse: Nach einer Beobachtungszeit von 4 Jahren wurden die multivariaten relativen Risiken (RR) berechnet und adjustiert. Das RR den kardiovaskulären Endpunkt zu erreichen war signifikant höher für Patienten, die mit LFC. (RR 2.33; 95% Konfidenzintervall [CI] 1.38-3.94; p=0.002), LFSS (RR 1.92; 95% CI 1.35-2.73; p=0.0003) oder LFS (RR 1.35; 95% CI, 0.99-1.85; p=0.06) Membranen dialysiert wurden, als für Patienten, die mit HFS behandelt wurden. Entsprechend war das RR zu sterben höher bei Dialyse mit LFC (RR 4.14; 95 %CI 2.79-6.15; p<0.0001 ) LFSS (RR 2.24; 95% CI 1.66-3.02; p<0.0001), LFS (RR 0.45; 95% CI 1.22-2.07; p=0.0006) als bei Dialyse mit HFS . Auch im Vergleich zu Patienten, die mit LFS behandelt wurden, zeigte sich für LFC ein um 161% höheres RR (95% CI 1.80-3.79; p<0.0001) und für LFSS ein um 41% höheres RR (95% CI 1.07-1.86; p=0.016) zu sterben. Schließlich war bei Vergleich von LFC und LFSS das RR zu sterben bei Patienten, die mit LFC dialysiert wurden um 85% höher (95% CI 1.24-2.76; p=0.0025). Die geringste Rate an Todesfällen zeigte sich in der HFS-Gruppe; die kumulative Inzidenz betrug 12% nach 1 und 33% nach 3 Jahren. Am höchsten war die Gesamtmortalität in der LFC-Gruppe mit 44% und 84% nach 1 bzw. 3 Jahren. Gleichfalls signifikante Unterschiede zeigten sich für die Vergleiche mit LFS und LFSS. Ein ähnliches Bild ergibt sich bei der Betrachtung der Kaplan Meier Überlebenskurven für den kardiovaskulären Endpunkt: Die kumulative Inzidenz betrug für HFS 12,3% nach 1 und 30,5% nach 3 Jahren und für LFC 24,3% nach 1 und 60,8% nach 3 Jahren. Schlussfolgerung: Biokompatibilität und Flux von Dialysemembranen haben Einfluss auf die Prognose hämodialysepflichtiger Typ 2 diabetischer Patienten. N2 - Background: Effects of dialyzer membrane characteristics on morbidity and mortality are highly controversial. Methods: Post hoc, we analyzed data of the German Diabetes and Dialysis Study, evaluating atorvastatin in high risk patients. Before analysis of the data the patients were grouped along the prescribed membranes; corresponding to their permeability and flux we differed low- and high-flux and corresponding to biocompatibility we differed in cellulosic, semisynthetic and synthetic membranes. Four groups were identified being constantly dialyzed with high-flux synthetic (HFS) (n=241), low-flux synthetic (LFS) (n=247), low-flux semisynthetic (LFSS) (n=119) or cellulosic low-flux membranes (LFC) (n=41). Two endpoints were investigated, a cardiovascular (CV) endpoint consisting of cardiac death, nonfatal myocardial infarction, and stroke, as well as death. Results: After 4 years follow-up, adjusted multivariate relative risks (RR) were calculated. The RR to reach a CV endpoint was higher for patients dialyzed with LFC [RR 2.33; 95% Confidence interval (CI) 1.38-3.94; p=0.002], LFSS (RR 1.92; 95% CI 1.35-2.73; p=0.0003) or LFS (RR 1.35; 95% CI 0.99-1.85; p=0.06) than for patients treated with HFS dialyzers. The likelihood to die was higher with LFC (RR 4.14; 95% CI 2.79-6.15; p<0.0001), LFSS (RR 2.24; 95% CI 1.66-3.02; p<0.0001) and LFS (RR 1.59; 95% CI 1.22-2.07; p=0.0006) than with HFS membranes. With respect to LFS, the RR of mortality for patients on LFC and LFSS membranes was 161% (RR 2.61; 95 % CI 1.80-3.79; p<0.0001) and 41% (RR 1.41; 95% CI 1.07-1.86; p=0.016) higher. LFC was associated with 85% (RR 1.85; 95% CI 1.24-2.76; p=0.0025) higher RR of death than LFSS membranes. Conclusion: These data suggest, that biocompatibility and permeability may impact on death and cardiovascular events in hemodialysis patients with type 2 diabetes mellitus.

In der multivariaten Regressionsanalyse waren sowohl NT-proBNP als auch Troponin T jeweils starke unabhängige Prädiktoren für plötzlichen Herztod, Schlaganfall und die Gesamtmortalität. Eine Assoziation von NT-proBNP mit dem Auftreten von Myokardinfarkten wurde nicht gesehen.

Patients with increasing baseline NT-proBNP and Troponin T exhibited a higher risk of sudden death, stroke, and all-cause mortality. In multivariate regression analysis both, NT-proBNP and Troponin T, were independent predictors of sudden death, stroke, and all-cause mortality. Neither baseline nor change in NT-proBNP was significantly associated with myocardial infarction. Increased longitudinal levels of NT-proBNP and Troponin T during follow up were associated with higher risks of adverse cardiovascular outcomes and death.

Interventional strategies aiming to reduce levels of FGF-23 in HD patients are of particular interest. The purpose of the current study was to compare the impact of high-flux versus low-flux HD on circulating FGF-23 levels. Methods We conducted a post-hoc analysis of the MINOXIS study, including 127 dialysis patients randomized to low-flux (n = 62) and high-flux (n = 65) HD for 52 weeks. Patients with valid measures for FGF-23 investigated baseline and after 52 weeks were included. Results Compared to baseline, a significant increase in FGF-23 levels after one year of low-flux HD was observed (Delta plasma FGF-23: +4026 RU/ml; p < 0.001). In contrast, FGF-23 levels remained stable in the high flux group (Delta plasma FGF-23: +373 RU/ml, p = 0.70). The adjusted difference of the absolute change in FGF-23 levels between the two treatment groups was statistically significant (p < 0.01). Conclusions Over a period of 12 months, high-flux HD was associated with stable FGF-23 levels, whereas the low-flux HD group showed an increase of FGF-23. However, the implications of the different FGF 23 time-trends in patients on high flux dialysis, as compared to the control group, remain to be explored in specifically designed clinical trials.
