However, available flood maps in West Africa lack spatial variability while global datasets have resolutions too coarse to be relevant for local scale risk assessment. Consequently, local disaster managers are forced to use traditional methods such as watermarks on buildings and media reports to identify flood hazard areas. In this study, remote sensing and Geographic Information System (GIS) techniques were combined with hydrological and statistical models to delineate the spatial limits of flood hazard zones in selected communities in Ghana, Burkina Faso and Benin. The approach involves estimating peak runoff concentrations at different elevations and then applying statistical methods to develop a Flood Hazard Index (FHI). Results show that about half of the study areas fall into high intensity flood zones. Empirical validation using statistical confusion matrix and the principles of Participatory GIS show that flood hazard areas could be mapped at an accuracy ranging from 77\% to 81\%. This was supported with local expert knowledge which accurately classified 79\% of communities deemed to be highly susceptible to flood hazard. The results will assist disaster managers to reduce the risk to flood disasters at the community level where risk outcomes are first materialized.}, language = {en} } @article{BrumbergSchroeterBlazhenetsetal.2020, author = {Brumberg, Joachim and Schr{\"o}ter, Nils and Blazhenets, Ganna and Frings, Lars and Volkmann, Jens and Lapa, Constantin and Jost, Wolfgang H. and Isaias, Ioannis U. and Meyer, Philipp T.}, title = {Differential diagnosis of parkinsonism: a head-to-head comparison of FDG PET and MIBG scintigraphy}, series = {NPJ Parkinsons Disease}, volume = {6}, journal = {NPJ Parkinsons Disease}, doi = {10.1038/s41531-020-00141-y}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-230675}, year = {2020}, abstract = {[\(^{18}\)F]fluorodeoxyglucose (FDG) PET and [\(^{123}\)I]metaiodobenzylguanidine (MIBG) scintigraphy may contribute to the differential diagnosis of neurodegenerative parkinsonism. To identify the superior method, we retrospectively evaluated 54 patients with suspected neurodegenerative parkinsonism, who were referred for FDG PET and MIBG scintigraphy. Two investigators visually assessed FDG PET scans using an ordinal 6-step score for disease-specific patterns of Lewy body diseases (LBD) or atypical parkinsonism (APS) and assigned the latter to the subgroups multiple system atrophy (MSA), progressive supranuclear palsy (PSP), or corticobasal syndrome. Regions-of-interest analysis on anterior planar MIBG images served to calculate the heart-to-mediastinum ratio. Movement disorder specialists blinded to imaging results established clinical follow-up diagnosis by means of guideline-derived case vignettes. Clinical follow-up (1.7 +/- 2.3 years) revealed the following diagnoses: n = 19 LBD (n = 17 Parkinson's disease [PD], n = 1 PD dementia, and n = 1 dementia with Lewy bodies), n = 31 APS (n = 28 MSA, n = 3 PSP), n = 3 non-neurodegenerative parkinsonism; n = 1 patient could not be diagnosed and was excluded. Receiver operating characteristic analyses for discriminating LBD vs. non-LBD revealed a larger area under the curve for FDG PET than for MIBG scintigraphy at statistical trend level for consensus rating (0.82 vs. 0.69, p = 0.06; significant for investigator \#1: 0.83 vs. 0.69, p = 0.04). The analysis of PD vs. MSA showed a similar difference (0.82 vs. 0.69, p = 0.11; rater \#1: 0.83 vs. 0.69, p = 0.07).

It is suggested to increase nitric oxide availability, enhance endothelial function and to protect against cardiovascular diseases. We aimed to investigate the relation between homoarginine, kidney function and progression of chronic kidney disease (CKD). Methods: We measured plasma homoarginine concentrations in baseline samples of the Mild to Moderate Kidney Disease (MMKD) Study, a prospective cohort study of 227 patients with CKD in Europe. Homoarginine concentrations were available in 182 of the baseline samples and in 139 of the prospectively-followed patients. We correlated homoarginine concentrations to parameters of kidney function. The association between homoarginine and progression of CKD was assessed during a follow-up of up to seven years (median 4.45 years, interquartile range 2.54-5.19) using Cox regression analysis. Progression of CKD was defined as doubling of baseline serum creatinine and/or end-stage renal disease. Results: Study participants were at baseline on average 47 \(\pm\)13 years old and 65\% were male. Mean \(\pm\) standard deviation of homoarginine concentrations were \(2.5 \pm 1.1 \mu mol/L\) and concentrations were incrementally lower at lower levels of GFR with mean concentrations of \(2.90 \pm 1.02 \mu mol/L\) (GFR. 90 ml/min), \(2.64 \pm 1.06 \mu mol/L\) (GFR 60-90 ml/min), \(2.52 \pm 1.24 \mu mol/L\) (GFR 30-60 ml/min) and \(2.05 \pm 0.78 \mu mol/L\) (GFR, 30 ml/min), respectively (p = 0.002). The age-and sex-adjusted risk to reach the renal endpoint was significantly higher by 62\% with each decrease by one standard deviation (\(1.1 \mu mol/L\)) of homoarginine (HR 1.62, 95\% CI 1.16-2.27, p = 0.005). This association was independent of proteinuria (HR 1.56, 95\% CI 1.11-2.20, p = 0.01), and was slightly attenuated when adjusting for GFR (HR 1.40 (95\% CI 0.98-1.98, p = 0.06). Conclusions: Homoarginine concentrations are directly correlated with kidney function and are significantly associated with the progression of CKD. Low homoarginine concentrations might be an early indicator of kidney failure and a potential target for the prevention of disease progression which needs further investigations.}, language = {en} } @article{DrozdSaenkoBrenneretal.2015, author = {Drozd, Valentina M. and Saenko, Vladimir A. and Brenner, Alina V. and Drozdovitch, Vladimir and Pashkevich, Vasilii I. and Kudelsky, Anatoliy V. and Demidchik, Yuri E. and Branovan, Igor and Shiglik, Nikolay}, title = {Major Factors Affecting Incidence of Childhood Thyroid Cancer in Belarus after the Chernobyl Accident: Do Nitrates in Drinking Water Play a Role?}, series = {PLoS One}, volume = {10}, journal = {PLoS One}, number = {9}, doi = {10.1371/journal.pone.0137226}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-141863}, pages = {e0137226}, year = {2015}, abstract = {One of the major health consequences of the Chernobyl Nuclear Power Plant accident in 1986 was a dramatic increase in incidence of thyroid cancer among those who were aged less than 18 years at the time of the accident. This increase has been directly linked in several analytic epidemiological studies to iodine-131 (I-131) thyroid doses received from the accident. However, there remains limited understanding of factors that modify the I-131-related risk. Focusing on post-Chernobyl pediatric thyroid cancer in Belarus, we reviewed evidence of the effects of radiation, thyroid screening, and iodine deficiency on regional differences in incidence rates of thyroid cancer. We also reviewed current evidence on content of nitrate in groundwater and thyroid cancer risk drawing attention to high levels of nitrates in open well water in several contaminated regions of Belarus, i.e. Gomel and Brest, related to the usage of nitrogen fertilizers. In this hypothesis generating study, based on ecological data and biological plausibility, we suggest that nitrate pollution may modify the radiation-related risk of thyroid cancer contributing to regional differences in rates of pediatric thyroid cancer in Belarus.

Objective: We aimed to externally validate the proposed asthma prediction method in a German birth cohort. Methods: The MAS-90 study (Multicentre Allergy Study) recorded details on allergic diseases prospectively in about yearly follow-up assessments up to age 20 years in a cohort of 1,314 children born 1990. We replicated the scoring method from the Leicester cohort and assessed prediction, performance and discrimination. The primary outcome was defined as the combination of parent-reported wheeze and asthma drugs (both in last 12 months) at age 8. Sensitivity analyses assessed model performance for outcomes related to asthma up to age 20 years. Results: For 140 children parents reported current wheeze or cough at age 3 years. Score distribution and frequencies of later asthma resembled the Leicester cohort: 9\% vs. 16\% (MAS-90 vs. Leicester) of children at low risk at 3 years had asthma at 8 years, at medium risk 45\% vs. 48\%. Performance of the asthma prediction tool in the MAS-90 cohort was similar (Brier score 0.22 vs. 0.23) and discrimination slightly better than in the original cohort (area under the curve, AUC 0.83 vs. 0.78). Prediction and discrimination were robust against changes of inclusion criteria, scoring and outcome definitions. The secondary outcome 'physicians' diagnosed asthma at 20 years' showed the highest discrimination (AUC 0.89).

This requires regions of interest (ROIs) to be defined using the most recent imaging data. This study investigates the clinical utility of using deformable image registration (DIR) to automatically propagate ROIs. Methods: Target (GTV) and organ-at-risk (OAR) ROIs were non-rigidly propagated from a planning CT scan to a per-treatment CT scan for 22 patients. Propagated ROIs were quantitatively compared with expert physician-drawn ROIs on the per-treatment scan using Dice scores and mean slicewise Hausdorff distances, and center of mass distances for GTVs. The propagated ROIs were qualitatively examined by experts and scored based on their clinical utility. Results: Good agreement between the DIR-propagated ROIs and expert-drawn ROIs was observed based on the metrics used. 94\% of all ROIs generated using DIR were scored as being clinically useful, requiring minimal or no edits. However, 27\% (12/44) of the GTVs required major edits. Conclusion: DIR was successfully used on 22 patients to propagate target and OAR structures for ART with good anatomical agreement for OARs.

Different cancer syndromes such as a subtype of Xeroderma pigmentosum, XPF, and recently a subtype of Fanconi Anemia, FA-Q, have been attributed to biallelic ERCC4 gene mutations. To investigate whether monoallelic ERCC4 gene defects play some role in the inherited component of breast cancer susceptibility, we sequenced the whole ERCC4 coding region and flanking untranslated portions in a series of 101 Byelorussian and German breast cancer patients selected for familial disease (set 1, n = 63) or for the presence of the rs1800067 risk haplotype (set 2, n = 38). This study confirmed six known and one novel exonic variants, including four missense substitutions but no truncating mutation. Missense substitution p.R415Q (rs1800067), a previously postulated breast cancer susceptibility allele, was subsequently screened for in a total of 3,698 breast cancer cases and 2,868 controls from Germany, Belarus or Russia. The Gln415 allele appeared protective against breast cancer in the German series, with the strongest effect for ductal histology (OR 0.67; 95\%CI 0.49; 0.92; p = 0.003), but this association was not confirmed in the other two series, with the combined analysis yielding an overall Mantel-Haenszel OR of 0.94 (95\% CI 0.81; 1.08). There was no significant effect of p.R415Q on breast cancer survival in the German patient series. The other three detected ERCC4 missense mutations included two known rare variants as well as a novel substitution, p.E17V, that we identified on a p.R415Q haplotype background. The p.E17V mutation is predicted to be probably damaging but was present in just one heterozygous patient. We conclude that the contribution of ERCC4/FANCQ coding mutations to hereditary breast cancer in Central and Eastern Europe is likely to be small.}, language = {en} } @phdthesis{Lohr2007, author = {Lohr, Andreas}, title = {Risikostratifikation grosszelliger B-Zell Non-Hodgkin Lymphome anhand immunhistochemischer Parameter}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-23654}, school = {Universit{\"a}t W{\"u}rzburg}, year = {2007}, abstract = {Die diffusen großzelligen B-Zell-Lymphome (DLBCL) stellen den h{\"a}ufigsten Typ aller Non-Hodgkin-Lymphome dar, sind aber morphologisch, immunologisch, genetisch und klinisch eine sehr heterogene Gruppe. Aufgrund dieser Heterogenit{\"a}t von DLBCL wurde in mehreren Studien untersucht, ob eine molekulare Heterogenit{\"a}t der Tumoren vorl{\"a}ge, bzw. versucht, eine molekulare Reklassifikation zu erreichen. Resultat dieser Bem{\"u}hungen war eine Unterscheidung bzw. Definition einer Keimzentrums- {\"a}hnlichen (GCB-cell-like) Gruppe und einer aktivierten B-Zellen-{\"a}hnlichen (ABC-like) Gruppe, die sich in ihrem Ansprechen auf {\"u}bliche Therapieschemata, mit einer deutlich besseren Prognose f{\"u}r die GCB-like-Gruppe, unterschieden. Die hierbei angewendete Microarray-Technologie hat den entscheidenden Nachteil, dass hierf{\"u}r qualitativ hochwertige RNA zur Verf{\"u}gung stehen muss. Neu ist der Ansatz, unterschiedliche Proteinexpressionsmuster am Paraffinmaterial zur Unterscheidung prognostisch relevanter Gruppen heranzuziehen. Die hierbei erzielten Daten sind allerdings in Ihren Aussagen hinsichtlich der prognostischen Wertigkeiten widerspr{\"u}chlich. In der vorliegenden Arbeit wurden zun{\"a}chst verschiedene biologische Parameter am Paraffinmaterial hinsichtlich ihrer prognostischen Wertigkeit in der Risikostratifikation von DLBCL untersucht. In einem ersten Schritt wurden klinische Daten von 99 de novo entstandenen großzelligen B-Zell-Lymphomen erhoben, bei denen es sich um 84 DLBCL und um elf DLBCL mit einer weiteren Komponente eines follikul{\"a}ren Lymphoms Grad 3B bzw. auch um vier F{\"a}lle mit ausschließlich follikul{\"a}rem Wachstumsmuster handelte. Die Klassifikation der F{\"a}lle nach dem Internationalen Prognostischen Index (IPI) sowie der einzelnen klinischen Parameter des IPI zeigte eine deutliche prognostische Relevanz. In einem zweiten Schritt wurden immunhistochemische F{\"a}rbungen mit verschiedenen Antik{\"o}rpern durchgef{\"u}hrt und auf ihre prognostische Bedeutung {\"u}berpr{\"u}ft. Als negative prognostische Parameter erwiesen sich die Negativit{\"a}t f{\"u}r CD10 sowie BCL-6, also Antigene, die mit einer Keimzentrumszell-Differenzierung assoziiert werden, sowie eine {\"U}berexpression von MUM-1, das mit einer postfollikul{\"a}ren Differenzierung assoziiert wird. Weiterhin konnte gezeigt werden, dass einer Expression von BCL-2 und einem Ki67-Index von unter 80 \% eine negative prognostische Bedeutung zukommt. Die Stratifikation der F{\"a}lle in einen GCB- und einen ABC- Typ anhand des Hans-Klassifikators zeigte nur eine schwache Korrelation zur {\"U}berlebenswahrscheinlichkeit. In einem dritten Schritt wurde gezeigt, dass die kombinierte Analyse jeweils zweier Parameter eine relative Abh{\"a}ngigkeit ihrer Expression von der Expression weiterer Marker erkennen ließ. Aus diesem Grunde wurde ein Modell einer sequentiellen Addition negativer prognostischer Indikatoren entwickelt, in der bei Anwesenheit einer negativen Variable (CD10-Negativit{\"a}t, BCL-6 < 20\%, BCL-2 positiv, MUM-1\&\#8805; 50\% und Ki67 < 80\%) ein negativer Faktor gewertet und die Summe dieser als Risiko-Score angegeben wurde. Die Stratifikation der Patienten anhand dieses „kombinierten immunhistochemischen Risiko-Scores" zeigte drei prognostisch deutlich unterschiedliche Gruppen: In der Gruppe von Patienten ohne Risikofaktoren verstarb lediglich eine Patientin (die eine Behandlung abgelehnt hatte); in der Hochrisikogruppe (Score 5) verstarben alle Patienten innerhalb eines Jahres. Die multivariate Analyse des Scores ergab dabei eine Unabh{\"a}ngigkeit von den Parametern des IPI. In der intermedi{\"a}ren Gruppe mit einem Risiko-Score von 1-4 zeigten sich der IPI sowie eine LDH-Erh{\"o}hung und das Vorhandensein einer B-Symptomatik als geeignete Parameter, um hier eine weitere Stratifizierung durchzuf{\"u}hren.

(i) Induction and saturation of enzymatic activation and detoxification processes and of DNA repair affect the relationship between dose and steady-state DNA adduct Ievel; (ii) The fixation of DNA adducts in the form of mutations is accelerated by stimulation of the cell division, for Jnstance due to regenerative hyperplasia at cytotoxic dose Ievels; (iii) The rate of tumor formation results from a superposition of the rates of the individual steps. It can become exponential with dose if more than one step is accelerated by the DNA damage exerted by the genotoxic carcinogen. The strongly sigmoidal shapes often observed for dose-tumor incidence relationships in animal bioassays supports this analysis. A power of four for the dose in the su~linear part of the curve is the maximum observed (formaldehyde). In contrast to animal experiments, epidemiological data ln humans rarely show a slgnificant deviation from linearity. The discrepancy might be explained by the fact that a I arge nu mber of genes contribute to the overall sensitivity of an individual and to the respective heterogeneity within the human population. Mechanistic nonlinearities are flattened out in the presence of genetic and life-style factors which affect the sensitivity for the development of cancer.
