TY - THES A1 - Lanz, Meike Berit T1 - Lebensqualität und Bedürfnisse von Patientinnen mit metastasiertem Brustkrebs - Eine Erhebung im Rahmen der Pilotphase des BRE-4-MED-Projektes T1 - Quality of life and needs of patients with metastatic breast cancer - A survey within the pilot phase of the BRE-4-MED project N2 - Die Ziele dieser Arbeit waren, das aktuelle Informationsbedürfnis von metastasierten Brustkrebspatientinnen und -patienten, deren Einschätzung der Arzt-Patient-Kommunikation sowie erwiesene Prädiktoren der QoL zu erheben und auf einen Zusammenhang mit der aktuellen patientenseitigen QoL zu untersuchen. Zu dieser oder ähnlichen Fragestellungen existieren lediglich Publikationen mit Brustkrebspatientinnen ohne Metastasierung. Studien mit ausschließlich metastasierten Brustkrebs-patientinnen sind generell sehr selten. Die Daten von 30 Patientinnen und einem Patienten mit metastasiertem Brustkrebs, rekrutiert in vier Kliniken in Bayern und Baden-Württemberg im Rahmen der Pilotphase des BRE-4-MED-Projektes, konnten ausgewertet werden. Die Studienteilnehmer waren zum Zeitpunkt der Rekrutierung zwischen 30 und 85 Jahre alt, das Durchschnittsalter betrug 57 Jahre (SD = 13,4). Für die Datenerhebung wurden nebst einzelner ordinalskalierter Fragen standardisierte, teils modifizierte Fragebögen wie die CARE-Skala, PROMIS PF4a, PHQ-4 oder ein Item des EORTC QLQ-C30 verwendet. In der QoL-Messung durch ein Item des EORTC QLQ-C30 Fragebogens erzielten die Probandinnen und Probanden geringfügig schlechtere Werte als eine gesunde deutsche Vergleichspopulation. Angesichts bisheriger Forschungsergebnisse wurde mit unbefriedigten Informations- und Kommunikationsbedürfnissen gerechnet. Außerdem wurden Zusammenhänge zwischen der QoL und unbefriedigten Informationsbedürfnissen, einer schlechten Arzt-Patient-Kommunikation sowie Prädiktoren der QoL erwartet. Diese Hypothesen wurden durch die vorliegende Arbeit zum Teil bestätigt, nämlich das Vorliegen von unerfüllten Informationsbedürfnissen sowie einer Korrelation der QoL mit Depression, körperlicher Funktionalität und mit Schmerz. Ein Zusammenhang mit dem Alter der Befragten bestand, jedoch genau entgegengesetzt der Erwartung. Letzteres Ergebnis sowie die nicht signifikanten Ergebnisse der Studie sind am ehesten durch eine zu geringe Probandenzahl bedingt. In puncto Informationsbedürfnisse der Patienten sowie Prädiktoren der QoL konnte die vorliegende Arbeit die bisherige Forschung größtenteils bestätigen, woraus die ärztlichen Handlungsempfehlungen abgeleitet werden können, auf diese Themen im Umgang mit metastasierten Mammakarzinompatienten besonders einzugehen. Die Aussagekraft der vorliegenden Ergebnisse ist allerdings angesichts der bisherigen Stichprobengröße als gering einzustufen, die Wiederholung der durchgeführten Analysen in der Hauptphase des BRE-4-MED-Projektes wären wünschenswert. Das BRE-4-MED-Register ist zusammenfassend als vielversprechendes Projekt zur Ergänzung der Versorgungsforschung und langfristig zur Verbesserung der Versorgung metastasierter Brustkrebspatienten einzustufen. N2 - The objectives of this work were to survey the current information needs of metastatic breast cancer patients, their assessment of physician-patient communication and proven predictors of QoL, and to examine for a correlation with current patient QoL. Only publications with breast cancer patients without metastasis exist on this or similar questions. Studies with exclusively metastasized breast cancer patients are generally rare. The data of 30 female patients and one male patient with metastatic breast cancer, recruited in four hospitals in Bavaria and Baden-Württemberg within the pilot phase of the BRE-4-MED project, could be analyzed. The study participants were between 30 and 85 years old at the time of recruitment, with a mean age of 57 years (SD = 13.4). For data collection, standardized, partly modified questionnaires such as the CARE scale, PROMIS PF4a, PHQ-4 or an item of the EORTC QLQ-C30 were used in addition to single ordinal scaled questions. In the QoL measurement, the patients scored slightly worse than a healthy German comparison population. Given previous research findings, unmet information and communication needs were expected. In addition, correlations between QoL and unmet information needs, poor physician-patient communication and predictors of QoL were expected. These hypotheses were partially confirmed by the present work, namely the presence of unmet information needs and a correlation of QoL with depression, physical functionality and with pain. A correlation with the age of the respondents existed, but opposite to the expectation. The latter result as well as the non-significant results of the study are most likely due to an insufficient number of subjects. With regard to the information needs of the patients as well as predictors of QoL, the present study was able to confirm previous research to a large extent, from which the physicians' recommendations for action can be derived to pay special attention to these topics in dealing with metastasized breast cancer patients. However, given the sample size to date, the significance of the present results must be considered low, and repetition of the analyses performed in the main phase of the BRE-4-MED project would be desirable. In summary, the BRE-4-MED registry can be classified as a promising project to complement health services research and, in the long term, to improve the care of metastatic breast cancer patients.

Es wurden Schreisequenzen von 20 gesunden Säuglingen bezüglich einfacher Rhythmuskomponenten analysiert und verschiedene temporalen Eigenschaften untersucht. Perspektivisch dient dies einer vorsprachlichen Diagnostik, die in Zukunft nicht-invasiv prognostische Aussagen für ein Risiko von Säuglingen mit und ohne orofaziale Spaltbildungen für Sprachentwicklungsverzögerungen treffen könnte. Dies würde eine frühzeitige logopädische und sprachtherapeutische Unterstützung prädisponierter Säuglinge ermöglichen. Es wurden 20 Säuglinge von der ersten bis zur zwölften Lebenswoche untersucht. Dabei wurden insgesamt 3,22 Stunden Säuglingsschreie interaktiv segmentiert. Als rhythmische Komponenten wurden die Strophen, Substrophen sowie das Inter-onset Intervall (IOI) untersucht. Während für die Strophenlänge knapp keine signifikante Altersabhängigkeit nachgewiesen werden konnte, zeigten sich die Länge von Substrophen sowie IOIs als signifikant mit dem Säuglingsalter zunehmend. Dies kann als Hinweis einer sich im Altersverlauf steigernden neurophysiologischen Fähigkeit zur Produktion längerer rhythmischer Vokalisationsmuster gedeutet werden. Signifikante geschlechtsspezifische Unterschiede konnten dabei nur auf Ebene der Strophen gefunden wurden. Die Rhythmuskomponenten Substrophe und IOI lieferten hingegen insgesamt keine Hinweise auf signifikante Entwicklungsunterschiede zwischen weiblichen und männlichen Säuglingen. Die vorliegende Arbeit liefert damit Analyseergebnisse für rhythmische Komponenten von Säuglingsvokalisationen im Verlauf der ersten drei Lebensmonate. Diese können als Ausgangswerte für künftige Studien mit Einschluss von Säuglingen mit orofazialen Malformationen dienen und dabei helfen, diagnostisch relevante Messgrößen zur frühzeitigen Identifikation von Risikokindern zu definieren. N2 - The aim of this study was to systematically investigate vocalization sequences over the first three months of life in infants without orofacial clefts and subsequently with normal speech acquisition. The sequences of 20 healthy infants were analyzed with respect to simple rhythmic components and different temporal properties. This research is intended to provide insights which could be used in the future to develope non-invasive prognostic diagnosis about the risk of infants with and without orofacial clefts for speech developmental disorders. This would allow early speech and language therapy support for predisposed infants. Twenty infants were evaluated and a total of 3.22 hours of infant cries were interactively segmented. The rhythmic components examined were verses, sub-verses, and the inter-onset interval (IOI). While no significant age dependency was found for the verse length, the length of sub-verses and IOIs increased significantly with infant age. This can be interpreted as an indication of an increasing neurophysiological ability to produce longer rhythmic vocalization patterns. Significant gender differences were found only at the level of the verses. In contrast, the rhythm components sub-verse and IOI did not provide overall evidence for significant gender differences. This study provides analytical results for rhythmic components of infant vocalizations over the course of the first three months of life. These may serve as reference values for future studies including infants with orofacial malformations and help to define diagnostically relevant measurements for early identification of infants at risk of speech development disorders.

Ihre Entstehung ist von multiplen Faktoren abhängig. So scheinen genetische Faktoren, das Rauchen der Mutter oder die Einnahme bestimmter Medikamente in der Schwangerschaft, Schilddrüsen- und Stoffwechselerkrankungen einen Einfluss zu haben. Die Koronarnahtsynostose stellt mit einer Inzidenz von 20 % die zweithäufigste Form der prämaturen Synostosen dar. Bei dem vorzeitigen unilateralen Nahtverschluss kommt es zur Entwicklung eines anterioren Plagiozephalus. Bei einer beidseitigen Koronarnahtsynostose entsteht ein brachy-turrizephaler Schädel. Die frühzeitige Diagnose ist wichtig, damit die betroffenen Kinder frühestmöglich in ein optimales Betreuungs- und Therapiekonzept eingebunden werden können. Bei Einzelnahtsynostosen sind meist bereits die untersuchten klinischen Parameter zur Diagnosestellung ausreichend und sollten um eine Sonographie und Röntgenaufnahmen in zwei Ebenen erweitert werden. Eine Indikation zur operativen Intervention stellt der Nachweis einer pathologischen intrakraniellen Drucksteigerung dar. Das Frontoorbitale Advancement ist die Operationstechnik der Wahl bei der Koronarnahtsynostose. Ziel der vorliegenden Dissertationsarbeit war die Weiterentwicklung bestehender kephalometrischer und kraniometrischer Messverfahren nach Slomic et al.. Dabei sollten der operative Therapieerfolg und der weitere Verlauf hinsichtlich einer Rezidivgefahr bewertet werden. In der vorliegenden Arbeit wurden Röntgenbilder des Carniofacialen Centrums Würzburg kraniometrisch ausgewertet. Das Patient*innenkollektiv wurde in zwei Gruppen untergliedert, und zwar Patient*innen mit einseitiger, nonsyndromaler Koronarnahtsynostose und Patient*innen mit beidseitiger, syndromaler Koronarnahtsynostose. Zur statistischen Auswertung erfolgte in beiden Patient*innengruppen die Untersuchung der Röntgenbilder zu vier festgelegten Zeitpunkten (00, 01, 02, 03). Die statistische Auswertung erfolgte mit dem Programm SPSS. Untersucht wurden der Gruppeneffekt und der Zeiteffekt hinsichtlich der 13 Strecken (LI, BRSt, BRPa, NO, PIS; SN, PIN, HI, NSt, SBR, PIBR, WI, AS) und fünf Winkel (ANS, SNBR, PIBRPa, BRNST, PISN). Da es in der Literatur eine unzureichende Erfassung von Strecken und Winkeln gibt, die die Veränderungen des Schädelwachstums erfassen, wurden die Strecken BRSt, BRPa, NSt, PIBR und AS sowie die fünf oben genannten Winkel neu definiert und entwickelt. Für die Röntgenzeitpunkte 00 und 01 zeigten sich für die Strecken und Winkel LI, BRSt, HI, NSt, SBR, PIBR, WI, PIBRPa und BRNST signifikante Unterschiede. Dies kann als OP-Erfolg gewertet werden. Der Kopf wird intraoperativ flacher und schmäler. Im weiteren Verlauf zeigte sich bei den Strecken BRSt, HI, PIBR und WI sowie bei den Winkeln PIBRPa und BRNST ein signifikanter Unterschied. Der Kopf wächst rezidivierend turrizephal. Im weiteren Untersuchungszeitraum wurde lediglich für die Strecken BRPa und AS ein signifikanter Unterschied ausgemacht. Zum einen Anzeichen eines im Wachstumsverlauf einsetzenden Rezidivs. Der Kopf wird wieder turrizephaler (BRPa). Zum anderen ist es Ausdruck einer beginnenden Mittelgesichtshypoplasie (AS). Weiterhin konnte über die Strecken SBR und PIBR gezeigt werden, dass Patient*innen mit beidseitiger Synostose eine turrizephalere Kopfform als die Vergleichsgruppe mit einseitiger Synostose aufweisen. Auffällig war außerdem das Ergebnis der beiden Winkel ANS und SNBR. Sie belegen, dass Patient*innen mit beidseitiger Synostose und Syndrom eine Mittelgesichtshypoplasie aufweisen. Als Fazit lässt sich sagen, dass die Strecken LI, BRSt, BRPa, HI, SBR, WI und AS sowie die Winkel SNBR, PIBRPa und ANS für weitere Untersuchungen geeignet scheinen. N2 - Premature craniosynostosis refers to premature ossification of one or more cranial sutures. Its development depends on multiple factors. Genetic factors, maternal smoking or the use of certain medications during pregnancy, thyroid and metabolic diseases seem to have an influence. Coronary suture synostosis is the second most common form of premature synostosis, with an incidence of 20%. Premature unilateral suture closure results in the development of anterior plagiocephaly. Bilateral coronal suture synostosis results in a brachy-turricephalic skull. Early diagnosis is important so that affected children can be integrated into an optimal care and treatment concept as early as possible. In the case of single-suture synostosis, the clinical parameters examined are usually sufficient to make a diagnosis and should be supplemented by sonography and x-rays in two planes. An indication for surgical intervention is the detection of a pathological intracranial pressure increase. Frontoorbital advancement is the surgical technique of choice for coronary suture synostosis. The aim of the present dissertation was to further develop existing cephalometric and craniometric measurement procedures according to Slomic et al.. The aim was to evaluate the success of the surgical therapy and the further course with regard to the risk of recurrence. In the present study, X-ray images from the Carniofacial Centre Würzburg were evaluated craniometrically. The patient collective was divided into two groups, namely patients with unilateral, nonsyndromal coronary suture synostosis and patients with bilateral, syndromal coronary suture synostosis. For statistical evaluation, the X-ray images of both groups of patients were examined at four fixed points in time (00, 01, 02, 03). The statistical analysis was performed with the SPSS programme. The group effect and the time effect were investigated with regard to the 13 distances (LI, BRSt, BRPa, NO, PIS; SN, PIN, HI, NSt, SBR, PIBR, WI, AS) and five angles (ANS, SNBR, PIBRPa, BRNST, PISN). As there is an insufficient coverage of distances and angles in the literature that capture the changes in cranial growth, the BRSt, BRPa, NSt, PIBR and AS distances and the five angles mentioned above were redefined and developed. For radiographic time points 00 and 01, there were significant differences for the LI, BRSt, HI, NSt, SBR, PIBR, WI, PIBRPa and BRNST distances and angles. This can be interpreted as a surgical success. The head becomes flatter and narrower intraoperatively. In the further course, there was a significant difference in the distances BRSt, HI, PIBR and WI as well as in the angles PIBRPa and BRNST. The head grows recurrently turricephalic. In the further investigation period, a significant difference was only found for the distances BRPa and AS. On the one hand, there are signs of recurrence during the course of growth. The head becomes more turricephalic again (BRPa). On the other hand, it is an expression of an incipient midface hypoplasia (AS). Furthermore, the SBR and PIBR sections showed that patients with bilateral synostosis have a more turricephalic head shape than the comparison group with unilateral synostosis. The results of the ANS and SNBR angles were also striking. They show that patients with bilateral synostosis and syndrome have midface hypoplasia. In conclusion, the LI, BRSt, BRPa, HI, SBR, WI and AS routes and the SNBR, PIBRPa and ANS angles seem suitable for further investigation.

Factors contributing to delayed diagnosis include health care professionals' limited knowledge of rare diseases and frequent (co-)occurrence of mental disorders that may complicate and delay the diagnostic process. The ZSE-DUO study aims to assess the benefits of a combination of a physician focusing on somatic aspects with a mental health expert working side by side as a tandem in the diagnostic process. Study design This multi-center, prospective controlled study has a two-phase cohort design. Methods Two cohorts of 682 patients each are sequentially recruited from 11 university-based German Centers for Rare Diseases (CRD): the standard care cohort (control, somatic expertise only) and the innovative care cohort (experimental, combined somatic and mental health expertise). Individuals aged 12 years and older presenting with symptoms and signs which are not explained by current diagnoses will be included. Data will be collected prior to the first visit to the CRD’s outpatient clinic (T0), at the first visit (T1) and 12 months thereafter (T2). Outcomes Primary outcome is the percentage of patients with one or more confirmed diagnoses covering the symptomatic spectrum presented. Sample size is calculated to detect a 10 percent increase from 30% in standard care to 40% in the innovative dual expert cohort. Secondary outcomes are (a) time to diagnosis/diagnoses explaining the symptomatology; (b) proportion of patients successfully referred from CRD to standard care; (c) costs of diagnosis including incremental cost effectiveness ratios; (d) predictive value of screening instruments administered at T0 to identify patients with mental disorders; (e) patients’ quality of life and evaluation of care; and f) physicians’ satisfaction with the innovative care approach. Conclusions This is the first multi-center study to investigate the effects of a mental health specialist working in tandem with a somatic expert physician in CRDs. If this innovative approach proves successful, it will be made available on a larger scale nationally and promoted internationally. In the best case, ZSE-DUO can significantly shorten the time to diagnosis for a suspected rare disease.

T1 - Similar severity of influenza primary and re-infections in pre-school children requiring outpatient treatment due to febrile acute respiratory illness: prospective, multicentre surveillance study (2013-2015) JF - BMC Infectious Diseases N2 - Background Influenza virus infections in immunologically naïve children (primary infection) may be more severe than in children with re-infections who are already immunologically primed. We compared frequency and severity of influenza virus primary and re-infections in pre-school children requiring outpatient treatment. Methods Influenza-unvaccinated children 1–5 years of age presenting at pediatric practices with febrile acute respiratory infection < 48 h after symptom onset were enrolled in a prospective, cross-sectional, multicenter surveillance study (2013–2015). Influenza types/subtypes were PCR-confirmed from oropharyngeal swabs. Influenza type/subtype-specific IgG antibodies serving as surrogate markers for immunological priming were determined using ELISA/hemagglutination inhibition assays. The acute influenza disease was defined as primary infection/re-infection by the absence/presence of influenza type-specific immunoglobulin G (IgG) and, in a second approach, by the absence/presence of subtype-specific IgG. Socio-demographic and clinical data were also recorded. Results Of 217 influenza infections, 178 were due to influenza A (87 [49%] primary infections, 91 [51%] re-infections) and 39 were due to influenza B (38 [97%] primary infections, one [3%] re-infection). Children with “influenza A primary infections” showed fever with respiratory symptoms for a shorter period than children with “influenza A re-infections” (median 3 vs. 4 days; age-adjusted p = 0.03); other disease characteristics were similar. If primary infections and re-infections were defined based on influenza A subtypes, 122 (87%) primary infections (78 “A(H3N2) primary infections”, 44 “A(H1N1)pdm09 primary infections”) and 18 (13%) re-infections could be classified (14 “A(H3N2) re-infections” and 4 “A(H1N1)pdm09 re-infections”). Per subtype, primary infections and re-infections were of similar disease severity. Children with re-infections defined on the subtype level usually had non-protective IgG titers against the subtype of their acute infection (16 of 18; 89%). Some patients infected by one of the influenza A subtypes showed protective IgG titers (≥ 1:40) against the other influenza A subtype (32/140; 23%). Conclusions Pre-school children with acute influenza A primary infections and re-infections presented with similar frequency in pediatric practices. Contrary to expectation, severity of acute “influenza A primary infections” and “influenza A re-infections” were similar. Most “influenza A re-infections” defined on the type level turned out to be primary infections when defined based on the subtype. On the subtype level, re-infections were rare and of similar disease severity as primary infections of the same subtype. Subtype level re-infections were usually associated with low IgG levels for the specific subtype of the acute infection, suggesting only short-time humoral immunity induced by previous infection by this subtype. Overall, the results indicated recurring influenza virus infections in this age group and no or only limited heterosubtypic antibody-mediated cross-protection.

So far, identification of potentially affected families in Germany was solely performed via family history and numbers of affected family members with breast or ovarian cancer. However, neither the prevalence of deleterious variants in \(BRCA1/2\) in ovarian cancer in Germany nor the reliability of family history as trigger for genetic counselling has ever been evaluated. Methods Prospective counseling and germline testing of consecutive patients with primary diagnosis or with platinum-sensitive relapse of an invasive epithelial ovarian cancer. Testing included 25 candidate and established risk genes. Among these 25 genes, 16 genes (\(ATM\), \(BRCA1\), \(BRCA2\), \(CDH1\), \(CHEK2\), \(MLH1\), \(MSH2\), \(MSH6\), \(NBN\), \(PMS2\), \(PTEN\), \(PALB2\), \(RAD51C\), \(RAD51D\), \(STK11\), \(TP53\)) were defined as established cancer risk genes. A positive family history was defined as at least one relative with breast cancer or ovarian cancer or breast cancer in personal history. Results In total, we analyzed 523 patients: 281 patients with primary diagnosis of ovarian cancer and 242 patients with relapsed disease. Median age at primary diagnosis was 58 years (range 16–93) and 406 patients (77.6%) had a high-grade serous ovarian cancer. In total, 27.9% of the patients showed at least one deleterious variant in all 25 investigated genes and 26.4% in the defined 16 risk genes. Deleterious variants were most prevalent in the \(BRCA1\) (15.5%), \(BRCA2\) (5.5%), \(RAD51C\) (2.5%) and \(PALB2\) (1.1%) genes. The prevalence of deleterious variants did not differ significantly between patients at primary diagnosis and relapse. The prevalence of deleterious variants in \(BRCA1/2\) (and in all 16 risk genes) in patients <60 years was 30.2% (33.2%) versus 10.6% (18.9%) in patients \(\geq\)60 years. Family history was positive in 43% of all patients. Patients with a positive family history had a prevalence of deleterious variants of 31.6% (36.0%) versus 11.4% (17.6%) and histologic subtype of high grade serous ovarian cancer versus other showed a prevalence of deleterious variants of 23.2% (29.1%) and 10.2% (14.8%), respectively. Testing only for \(BRCA1/2\) would miss in our series more than 5% of the patients with a deleterious variant in established risk genes. Conclusions 26.4% of all patients harbor at least one deleterious variant in established risk genes. The threshold of 10% mutation rate which is accepted for reimbursement by health care providers in Germany was observed in all subgroups analyzed and neither age at primary diagnosis nor histo-type or family history sufficiently enough could identify a subgroup not eligible for genetic counselling and testing. Genetic testing should therefore be offered to every patient with invasive epithelial ovarian cancer and limiting testing to \(BRCA1/2\) seems to be not sufficient.

T1 - Multiple antenatal dexamethasone treatment alters brain vessel differentiation in newborn mouse pups JF - PLoS ONE N2 - Antenatal steroid treatment decreases morbidity and mortality in premature infants through the maturation of lung tissue, which enables sufficient breathing performance. However, clinical and animal studies have shown that repeated doses of glucocorticoids such as dexamethasone and betamethasone lead to long-term adverse effects on brain development. Therefore, we established a mouse model for antenatal dexamethasone treatment to investigate the effects of dexamethasone on brain vessel differentiation towards the blood-brain barrier (BBB) phenotype, focusing on molecular marker analysis. The major findings were that in total brains on postnatal day (PN) 4 triple antenatal dexamethasone treatment significantly downregulated the tight junction protein claudin-5, the endothelial marker Pecam-1/CD31, the glucocorticoid receptor, the NR1 subunit of the N-methyl-D-aspartate receptor, and Abc transporters (Abcb1a, Abcg2 Abcc4). Less pronounced effects were found after single antenatal dexamethasone treatment and in PN10 samples. Comparisons of total brain samples with isolated brain endothelial cells together with the stainings for Pecam-1/CD31 and claudin-5 led to the assumption that the morphology of brain vessels is affected by antenatal dexamethasone treatment at PN4. On the mRNA level markers for angiogenesis, the sonic hedgehog and the Wnt pathway were downregulated in PN4 samples, suggesting fundamental changes in brain vascularization and/or differentiation. In conclusion, we provided a first comprehensive molecular basis for the adverse effects of multiple antenatal dexamethasone treatment on brain vessel differentiation.

N2 - HPP is a rare, hereditary metabolic disease that is associated with a disorder of bone and mineral metabolism. The aim of this study was to investigate the objectively measurable activity and HRQoL of young HPP patients. For this purpose, the data collected from the diseased patient group should be compared with the data of the healthy control group. This was done using accelerometry, spiroergometry and established questionnaires in 18 subjects and 18 health controls.

The coronavirus induced disease 2019 (COVID-19) pandemic and the resulting public policy responses represent an exceptional situation worldwide and there are hints for adverse psychosocial impact, hence, the study of psychological effects of the pandemic in women during hospitalization for delivery and in the postpartum period is highly relevant. Methods Patients who gave birth during the first wave of the COVID-19 pandemic in Germany (March to June 2020) at the Department of Obstetrics and Gynecology, University of Würzburg, Germany, were recruited at hospital admission for delivery. Biosamples were collected for analysis of SARS-CoV-2 infection and various stress hormones and interleukin-6 (IL-6). In addition to sociodemographic and medical obstetric data, survey questionnaires in relation to concerns about and fear of COVID-19, depression, stress, anxiety, loneliness, maternal self-efficacy and the mother–child bonding were administered at T1 (delivery stay) and T2 (3–6 months postpartum). Results In total, all 94 recruited patients had a moderate concern of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) at T1 with a significant rise at T2. This concern correlated with low to low-medium general psychosocial stress levels and stress symptoms, and the women showed a significant increase of active coping from T1 to T2. Anxiety levels were low and the Edinburgh Postnatal Depression Scale showed a medium score of 5 with a significant (T1), but only week correlation with the concerns about SARS-CoV-2. In contrast to the overall good maternal bonding without correlation to SARS-CoV-2 concern, the maternal self-efficiency correlated negatively with the obstetric impairment caused by the COVID-19 pandemic. Conclusion Obstetric patients` concerns regarding SARS-CoV-2 and the accompanying pandemic increased during the course of the pandemic correlating positively with stress and depression. Of note is the increase in active coping over time and the overall good mother–child-bonding. Maternal self-efficacy was affected in part by the restrictions of the pandemic.

The European Registry for rhabdoid tumors (EU‐RHAB) was established to generate a common European database and to establish a standardized treatment regimen as the basis for phase I/II trials. Thus, genetic analyses, neuropathologic and radiologic diagnoses, and a consensus treatment regimen were prospectively evaluated. From 2005 to 2009, 31 patients with AT/RT from four countries were recruited into the registry study Rhabdoid 2007 and treated with systemic and intraventricular chemotherapy. Eight patients received high‐dose chemotherapy, 23 radiotherapy, and 17 maintenance therapy. Reference evaluations were performed in 64% (genetic analyses, FISH, MLPA, sequencing) up to 97% (neuropathology, INI1 stain). Germ‐line mutations (GLM) were detected in 6/21 patients. Prolonged overall survival was associated with age above 3 years, radiotherapy and achievement of a complete remission. 6‐year overall and event‐free survival rates were 46% (±0.10) and 45% (±0.09), respectively. Serious adverse events and one treatment‐related death due to insufficiency of a ventriculo peritoneal shunt (VP‐shunt) and consecutive herniation were noted. Acquisition of standardized data including reference diagnosis and a standard treatment schedule improved data quality along with a survival benefit. Treatment was feasible with significant but manageable toxicity. Although our analysis is biased due to heterogeneous adherence to therapy, EU‐RHAB provides the best available basis for phase I/II clinical trials.

Medulloblastomas with c-myc amplification, classified as group 3, are the most aggressive among the four disease subtypes resulting in a 5-year overall survival of just above 50%. Despite current intensive therapy regimens, patients suffering from group 3 medulloblastoma urgently require new therapeutic options. Using a recently established c-myc amplified human medulloblastoma cell line, we performed an in-vitro-drug screen with single and combinatorial drugs that are either already clinically approved or agents in the advanced stage of clinical development. Candidate drugs were identified in vitro and then evaluated in vivo. Tumor growth was closely monitored by BLI. Vessel development was assessed by 3D light-sheet-fluorescence-microscopy. We identified the combination of gemcitabine and axitinib to be highly cytotoxic, requiring only low picomolar concentrations when used in combination. In the orthotopic model, gemcitabine and axitinib showed efficacy in terms of tumor control and survival. In both models, gemcitabine and axitinib were better tolerated than the standard regimen comprising of cisplatin and etoposide phosphate. 3D light-sheet-fluorescence-microscopy of intact tumors revealed thinning and rarefication of tumor vessels, providing one explanation for reduced tumor growth. Thus, the combination of the two drugs gemcitabine and axitinib has favorable effects on preventing tumor progression in an orthotopic group 3 medulloblastoma xenograft model while exhibiting a favorable toxicity profile. The combination merits further exploration as a new approach to treat high-risk group 3 medulloblastoma.

Maximum accuracy in predicting pathological tumor size non-invasively is critical for individualized therapy and surgical planning. We therefore aimed to assess the accuracy of tumor size measurement by ultrasound and mammography in a multicentered health services research study. Methods We retrospectively analyzed data from 6543 patients with unifocal, unilateral primary breast cancer. The maximum tumor diameter was measured by ultrasound and/or mammographic imaging. All measurements were compared to final tumor diameter determined by postoperative histopathological examination. We compared the precision of each imaging method across different patient subgroups as well as the method-specific accuracy in each patient subgroup. Results Overall, the correlation with histology was 0.61 for mammography and 0.60 for ultrasound. Both correlations were higher in pT2 cancers than in pT1 and pT3. Ultrasound as well as mammography revealed a significantly higher correlation with histology in invasive ductal compared to lobular cancers (p < 0.01). For invasive lobular cancers, the mammography showed better correlation with histology than ultrasound (p = 0.01), whereas there was no such advantage for invasive ductal cancers. Ultrasound was significantly superior for HR negative cancers (p < 0.001). HER2/neu positive cancers were also more precisely assessed by ultrasound (p < 0.001). The size of HER2/neu negative cancers could be more accurately predicted by mammography (p < 0.001). Conclusion This multicentered health services research approach demonstrates that predicting tumor size by mammography and ultrasound provides accurate results. Biological tumor features do, however, affect the diagnostic precision.

It is still unclear, whether targeted suppression of Interleukin (IL)-17 is able to influence regulatory function of Treg to control pro-inflammatory effectors in JIA. This study aimed to assess the effect of a Th17-stimulating cytokine environment and of IL-17A-inhibition on phenotype plasticity and suppressive function of Treg derived from JIA patients. Methods Th17 and Treg characteristics of CD4\(^{+}\) helper T cells were investigated in blood samples of JIA patients with oligo- and polyarticular pattern and healthy controls (HC). Isolated CD4\(^{+}\)CD25\(^{+}\)CD127\(^{-}\) cells defined as Treg were cultivated with Th17-inducing cytokine environment as well as with IL-17A-inhibitors and analyzed for plasticity of phenotype by flow cytometry. Furthermore, inhibitory function of Treg on autologous effectors after cultivation with these stimuli was determined by suppression assays. Results Our findings demonstrated significantly elevated proportions of Th17 and Th17-like Treg in JIA compared to HC. After incubation with Th17-inducing stimuli, increased FoxP3 expression in separated Treg in JIA and an impaired suppressive capacity in JIA and HC were found. Blockade of IL-17A resulted in adjustment of FoxP3-expression in JIA to proportions found in controls and in regular suppressive function. Conclusions Our results demonstrate an induction of FoxP3 expressing Treg by Th17-inducing cytokines with concomitant mitigated suppressive function. In contrast, specific IL-17A blockade maintains suppressive Treg function and adjusted FoxP3-expression in JIA to levels found in controls. These findings may help to provide experimental evidence for the successful clinical use of IL-17A inhibition in JIA patients.

T1 - A partially supervised physical activity program for adult and adolescent survivors of childhood cancer (SURfit): study design of a randomized controlled trial [NCT02730767] JF - BMC Cancer N2 - Background: Beyond survival of nowadays >80%, modern childhood cancer treatment strives to preserve long-term health and quality of life. However, the majority of today’s survivors suffer from short- and long-term adverse effects such as cardiovascular and pulmonary diseases, obesity, osteoporosis, fatigue, depression, and reduced physical fitness and quality of life. Regular exercise can play a major role to mitigate or prevent such late-effects. Despite this, there are no data on the effects of regular exercise in childhood cancer survivors from randomized controlled trials (RCTs). \(Primary\) \(outcome\) of the current RCT is therefore the effect of a 12-months exercise program on a composite cardiovascular disease risk score in childhood cancer survivors. \(Secondary\) \(outcomes\) are single cardiovascular disease risk factors, glycaemic control, bone health, body composition, physical fitness, physical activity, quality of life, mental health, fatigue and adverse events (safety). Methods: A total of 150 childhood cancer survivors aged ≥16 years and diagnosed ≥5 years prior to the study are recruited from Swiss paediatric oncology clinics. Following the baseline assessments patients are randomized 1:1 into an intervention and control group. Thereafter, they are seen at month 3, 6 and 12 for follow-up assessments. The intervention group is asked to add ≥2.5 h of intense physical activity/week, including 30 min of strength building and 2 h of aerobic exercises. In addition, they are told to reduce screen time by 25%. Regular consulting by physiotherapists, individual web-based activity diaries, and pedometer devices are used as motivational tools for the intervention group. The control group is asked to keep their physical activity levels constant. Discussion: The results of this study will show whether a partially supervised exercise intervention can improve cardiovascular disease risk factors, bone health, body composition, physical activity and fitness, fatigue, mental health and quality of life in childhood cancer survivors. If the program will be effective, all relevant information of the SURfit physical activity intervention will be made available to interested clinics that treat and follow-up childhood cancer patients to promote exercise in their patients.

A1 - Fehrholz, Markus T1 - A20 is increased in fetal lung in a sheep LPS model of chorioamnionitis JF - Oxidative Medicine and Cellular Longevity N2 - Chorioamnionitis is associated with an increased risk of preterm birth and aggravates adverse outcomes such as BPD. Development of BPD is associated with chronic inflammatory reactions and oxidative stress in the airways which may be antenatally initiated by chorioamnionitis. A20 is an immunomodulatory protein involved in the negative feedback regulation of inflammatory reactions and is a possible regulator protein in oxidative stress reactions. The influence of chorioamnionitis on A20 gene regulation in the fetal lung is unknown. We characterized the influence of LPS and proinflammatory cytokines on A20 expression in human lung endothelial (HPMEC-ST1.6R) and epithelial (A549) cells in vitro by real-time PCR and/or western blotting and used a sheep model of LPS-induced chorioamnionitis for in vivo studies. To study the functional role of A20, endogenous A20 was overexpressed in HPMEC-ST1.6R and A549 cells. LPS induced proinflammatory cytokines in HPMEC-ST1.6R and A549 cells. Both LPS and/or proinflammatory cytokines elevated A20 at transcriptional and translational levels. Intra-amniotic LPS transiently increased IL-1β, IL-6, IL-8, and TNF-α mRNA levels in fetal lamb lungs, associated with an increase in A20 mRNA and protein levels. Overexpression of A20 reduced proinflammatory cytokines in vitro. Repeated LPS exposure induced LPS tolerance for proinflammatory cytokines and A20 in vitro and in vivo. Antenatal inflammation induced a transient increase in proinflammatory cytokines in the preterm fetal lung. The expression of proinflammatory cytokines increased expression of A20. Elevated A20 may have a protective role by downregulating chorioamnionitis-triggered fetal lung inflammation. A20 may be a novel target for pharmacological interventions to prevent chorioamnionitis-induced airway inflammation and lung damage, which can result in BPD later in life.

Bisher erfolgt die Evaluation des individuellen Benefits von getragenen Hörhilfen bzw. ihrer optimalen Einstellung bei Säuglingen und jüngeren Kleinkindern hauptsächlich durch verhaltensbeobachtende Methoden. Die Würzburger Universitätsklinik und Poliklinik für Hals-, Nasen- und Ohrenheilkunde, plastische und ästhetische Operationen war die erste Einrichtung deutschlandweit, die ein zweistufiges Neugeborenen-Hörscreening klinisch umgesetzt hat. Durch die frühe Identifikation sensorineuraler Hörbeeinträchtigungen bei Säuglingen hat sich auch der Therapiebeginn ins frühe Säuglingsalter verschoben. Dies macht ergänzende objektive Methoden zu gängigen medizinischen Testverfahren zur Evaluation der vokalen Entwicklung in Abhängigkeit von der Adjustierung der Hörhilfen erforderlich. Kooperationsprojekte zwischen der Klinik und Poliklinik für Hals-, Nasen- und Ohrenheilkunde, plastische und ästhetische Operationen und dem Zentrum für vorsprachliche Entwicklung und Entwicklungsstörungen der Poliklinik für Kieferorthopädie des Universitätsklinikums Würzburg haben das Ziel, die sprachentwicklungsrelevanten Schritte im ersten Lebensjahr in Abhängigkeit von der individuellen Hörleistung zu charakterisieren. Die vorliegende Arbeit ist in diese Projekte eingebettet. Die retrospektiv angelegte Pilotstudie hatte das Ziel, die kanonische Babbelphase von vier vergleichbaren Säuglingen mit hochgradiger sensorineuraler Hörbeeinträchtigung mithilfe einer Methode zu untersuchen, die für hörgesunde Kinder entwickelt und bisher nur an Kindern mit orofazialer Spaltbildung getestet wurde. Es ging darum, geeignete Testsignale dieser Probanden in Form von kanonischen Babbellauten aus einem Repertoire von etwa 20000 Vokalisationen messtechnisch zu selektionieren und diese Signale dann mit der zu testenden Phonations-Interaktions-Analysemethode (PAI-Methode) zu analysieren. Dazu wurden in der finalen Messung 335 kanonische Babbelsilben ausgewertet. Es mussten geeignete Messgrößen erarbeitet und getestet werden sowie die Analyseergebnisse auf ihre Validität geprüft werden. Es wurden dabei sowohl frequenzbasierte als auch zeitliche Messgrößen analysiert. Im Ergebnis der durchgeführten Analysen und Tests hat sich gezeigt, dass die PAI-Methode geeignet ist, um den Stand der Artikulationsentwicklung im Altersbereich der kanonischen Babbelphase zu evaluieren. Das gilt sowohl für die mit HDO-Hörgeräten versorgten Probanden als auch für die CI-Träger. Die Testsignale, die hier verwendet wurden, stammen von Probanden, die eine sehr gute Sprech- und Sprachentwicklung gezeigt haben. Die retrospektive Auswertung lieferte bereits für das Babbelalter Messergebnisse, die Werte im Bereich der in der Literatur angegebenen Referenzbereiche für hörgesunde Kinder erbrachten. Damit hat die vorliegende Arbeit nicht nur die prinzipielle Eignung der PAI-Methode für die quantitative Charakterisierung der kanonischen Babbellaute demonstriert, sondern gleichzeitig belegt, dass pädaudiologisch gut versorgte Kinder bereits vor dem eigentlichen Sprachbeginn Artikulationsleistungen zeigen, die jenen hörgesunder Kinder im Verlauf ihrer Entwicklung entsprechen. Methodische Einschränkungen fanden sich im Bereich des untersuchbaren Frequenzrepertoires und der hohen Störanfälligkeit für Hintergrundgeräusche. Die Möglichkeit einer diesbezüglichen Modifikation der Methode wäre zu prüfen. Diese Ergebnisse erlauben es nun in einem nächsten Schritt, einen systematischen Vergleich der Messgrößen zwischen hörgesunden und sensorineural hörbeeinträchtigten Kindern unter Einschluss der Hörtestergebnisse mithilfe der PAI-Methode vorzunehmen. Dazu scheinen besonders die hier analysierte Artikulationsgeschwindigkeit und weitere zeitliche Größen (Resonanzfrequenzübergangszeit, aktive Vokalartikulationszeit, exakte und mittlere Silbendauer) geeignet. Für weitergehende Untersuchungen und spezifische Vergleiche ist es jedoch zunächst erforderlich, für alle anderen hier untersuchten Kenngrößen kanonischer Babbellaute weitere systematische Untersuchungen an vergleichbar homogenen Datensätzen von sowohl hörgesunden als auch hörbeeinträchtigten Kindern vorzunehmen. N2 - Infants with profound sensorineural hearing loss who are diagnosed and treated early in life have better outcomes in speech and language development than children who are diagnosed at a later point. Up to now, the assessment of the individual benefit of wearing hearing aids as well as their ideal technical adjustment is made by behavioral observation methods. The Department of Otorhinolaryngology, Plastic and Aesthetic Surgery of the University Clinics of Würzburg was the first institution in Germany to implement a two-step neonatal hearing screening protocol in a clinical setting. Now, due to the early identification of sensorineural hearing impairment in infants, also the onset time of treatment has been shifted to early infancy. This demands new methods adding to the well-established clinical tests to evaluate the vocal development as a function of the adjustment of the hearing aids. Cooperation between the Deparment of Otorhinolaryngology, Plastic and Aesthetic Surgery of the University Clinics of Würzburg and the Center for Pre-speech Development and Developmental Disorders (Department of Orthodontics) aims at characterizing the relevant steps of language acquisition during the first year of life as a function of the individual hearing ability. This pilot study is part of these projects. Aim of this retrospective pilot study was to analyze the developmental stage of canonical babbling of four comparable infants with profound sensorineural hearing loss, using a method that was developed for normal hearing infants and previously only tested in children with cleft lip and palate. Suitable canonical babbling vocalizations were methodically selected from a total amount of about 20.000 vocalizations to finally analyze them using the phonation-articulation-interaction method (PAI-method). In the final measuring procedure, 335 canonical syllables were evaluated. It was necessary to test and establish suitable indicators and to verify the validity of the results. Frequency based as well as time based parameters were analyzed. As a result, it could be shown that the PAI-method is suitable to evaluate the state of articulatory development at the age of the canonical babbling stage. This showed for the test takers with hearing aids as well as for those with cochlear implant. The examined test signals were taken from probands with a very good speech- and language development. Their retrospective evaluation already in the babbling stage showed results that were within the reference range reported in the literature for normal hearing infants. It could be demonstrated not only that the PAI-method is suitable for the quantitative characterization of canonical babbling sounds, but also that hearing impaired children with a good provision of hearing aids can show the same pre-speech articulatory activity as children without hearing impairment at a comparable stage of development. Methodic constraints were faced regarding the analyzable frequency repertoire and the interference with background noise. A modification of the method regarding those issues is to be discussed. Further investigations should be undertaken with the now available method to compare defined indicators of hearing impaired and normal hearing children considering their individual hearing threshold. Especially the articulation rate and some temporal parameters that were analyzed here (resonance transition time, active vocal articulation time, minute and mean syllable duration) seem to be promising for further research. As a next step, it is necessary to lead further investigations on a comparably homogenous, bigger set of data of hearing impaired and normal hearing infants on the above mentioned parameters.

We hypothesized that cardiovascular prophylaxis with omega-3 fatty acids could benefit them. In our study, 20 children and adolescents (mean body mass index percentile: 99.1; mean age: 11.0 years) underwent two ambulatory 24 h Holter electrocardiography (ECG) recordings (before and after at least 3 months of omega-3 fatty acid supplementation). Time domain heart rate variability (HRV) and heart rate (HR) were examined for these patients. As a control, we used 24 h Holter ECG recordings of 94 nonobese children and adolescents. Time domain HRV parameters, which are indicators of vagal stimulation, were significantly lower in obese patients than in healthy controls, but HR was higher (standard deviation of the normal-to-normal [SDNN] interbeat intervals: −34.02%; root mean square of successive differences [RMSSD] between normal heartbeats: −40.66%; percentage of consecutive RR intervals [pNN50]: −60.24%; HR: +13.37%). After omega-3 fatty acid supplementation, time domain HRV parameters and HR of obese patients were similar to the values of healthy controls (SDNN interbeat intervals: −21.73%; RMSSD: −19.56%; pNN50: −25.59%; HR: +3.94%). Therefore, omega-3 fatty acid supplementation may be used for cardiovascular prophylaxis in obese children and adolescents.

Aufbauend auf den Vorgaben der S3-LL Palliativ Langversion 1.0 2015 wurde der Qualitätsindikator Reduktion Schmerz (QI RS) für den gesamten Zeitraum des stationären Aufenthalts erhoben. Der Qualitätsindikator Opioide und Laxantien wurde am 3. Tag des stationären Aufenthalts (QI OL T1) und am 3. Tag vor stationärer Entlassung (QI OL T2) erhoben. Ergebnisse: Bei 78,5% der Grundgesamtheit wurden moderate bis starke Schmerzen dokumentiert und für den QI RS eingeschlossen (419/534). Die Datengrundlage des QI RS war für die eingeschlossenen Fälle vollständig, da Schmerzanamnesen im Schmerzassessment der pflegerischen Dokumentation integriert sind: Unter den eingeschlossenen Fällen lag nach den Kriterien des QI RS bei insgesamt 73,5% (308/419) eine dokumentierte Schmerzreduktion vor. Bei 26,5% aller eingeschlossenen Fälle (111/419) lag nach den Kriterien des QI RS keine dokumentierte Schmerzreduktion vor. Unter jenen Fällen lag der Anteil der stationär Verstorbenen bei 64,0% (71/111). Es lag ein signifikanter Zusammenhang zwischen dem Fehlen einer dokumentierten Schmerzreduktion und dem Versterben vor (p<0,05). 73,4% (392/534) der Grundgesamtheit wurden für den QI OL T1 eingeschlossen, da eine Therapie mit Opioiden an T1 dokumentiert war. 75,8% (405/534) der Grundgesamtheit wurde für den QI OL T2 eingeschlossen, da eine Therapie mit Opioiden an T2 dokumentiert war. Aufgrund der Vollständigkeit der Routinedokumentation konnte die Auswertung des QI OL T1 bzw. des QI OL T2 bei allen eingeschlossenen Fällen vorgenommen werden: Am 3. Tag des stationären Aufenthalts lag der Anteil dokumentierter Laxantien bei Opioidtherapie mit 57,9% (227/392) etwas höher als am 3. Tag vor stationärer Entlassung mit 53,8% dokumentierter Laxantien bei Opioidtherapie (218/405). Unter den Fällen ohne Laxantien bei Opioidtherapie an T1 verstarben mit 58,8% (97/165) weniger als unter den Fällen ohne Laxantien bei Opioidtherapie an T2 mit 67,4% (126/187). Es zeigt sich sowohl für den QI OL T1 als auch für den QI OL T2 ein signifikanter Zusammenhang zwischen dem Fehlen dokumentierter Laxantien bei Opioidtherapie und dem Versterben (p<0,001). Schlussfolgerung: Die vorliegende Studie belegt die Sinnhaftigkeit der Evaluation von Qualitätsindikatoren für die Palliativversorgung. Exemplarisch zeigt die Erhebung des Qualitätsindikators Opioide und Laxantien in der Sterbephase, dass regelmäßig von der Leitlinienempfehlung abgewichen wird. In der Erweiterten S3-LL Palliativ Langversion 2.0 von 2019 wurde der genaue Erhebungszeitpunkt des „QI2: Reduktion Schmerz“ präzisiert: Eingeschlossen für die Erhebung sind nun alle Patienten mit starkem bzw. mittleren Schmerz „bei stationärer Aufnahme“. N2 - Background: The German S3 Guideline Palliative Care for patients with incurable cancer proposes the Quality Indicator (QI) „Reduction of Pain“ and the QI „Opioids and Laxatives“ to evaluate the quality of palliative care. Aim: To analyze these QI in cancer patients during their stay in a specialized palliative care unit. Methods: Data were collected retrospectively from patients‘ files of Interdisciplinary Center Palliative Care of Wuerzburg from the year 2015 and 2018. The QI „Reduction of Pain“ was analyzed continously from patients' first day to their last day on palliative care unit. The QI „Opioids and Laxatives“ was analyzed regarding the third day on the palliative care unit (T1) and the day 3 before dismissal (T2). Results: 534 files from cancer patients were analyzed in total. 419 of all patients were included in the QI „Reduction of Pain“ as well as 392 of them in the QI „Opioids and Laxatives“ T1 and 405 in the QI „Opioids and Laxatives“ T2. For 308 of 419 patients reduction of pain was documented (308/419, 73.5%). 227 of 392 patients were treated with opioids and laxatives at T1 and 218 of 405 patients were treated with opioids and laxatives at T2 (T1: 227/392, 57.9%, T2: 218/405, 53.8%). Regarding the QI „Reduction of Pain“ significant more deceased patients had no reduction of pain (71/111, 64.0%, p<0.05). Regarding the QI „Opioids and Laxatives“ T1 as well as the QI „Opioids and Laxatives“ T2 significant more deceased patients received opioids without laxatives (T1: 97/165, 58.8%, T2: 126/187, 67.4%, p<0,01). Conclusion: The QI were easy to assess using patients‘ files. Evaluation of QI isn’t reasonable during the whole stay, e.g. because of cancelling prescreption of laxatives in dying phase. Therefore the wording of the QI „Reduction of Pain“ was specified 2019 in the Extended S3 Guideline Palliative care for patients with incurable cancer. Since then the QI „Reduction of Pain“ refers to all “patients with the diagnosis “incurable cancer” (receiving generalist or specialist palliative care) and with moderate/severe pain at inpatient admission“.
