Model-based Segmentation and Fusion of 3D Computed Tomography and 3D Ultrasound of the Eye for Radiotherapy Planning

Computed Tomography (CT) represents the standard imaging modality for tumor volume delineation for radiotherapy treatment planning of retinoblastoma despite some inherent limitations. CT scan is very useful in providing information on physical density for dose calculation and morphological volumetric information but presents a low sensitivity in assessing the tumor viability. On the other hand, 3D ultrasound (US) allows a highly accurate definition of the tumor volume thanks to its high spatial resolution but it is not currently integrated in the treatment planning but used only for diagnosis and follow-up. Our ultimate goal is an automatic segmentation of gross tumor volume (GTV) in the 3D US, the segmentation of the organs at risk (OAR) in the CT and the registration of both modalities. In this paper, we present some preliminary results in this direction. We present 3D active contour-based segmentation of the eye ball and the lens in CT images; the presented approach incorporates the prior knowledge of the anatomy by using a 3D geometrical eye model. The automated segmentation results are validated by comparing with manual segmentations. Then, we present two approaches for the fusion of 3D CT and US images: (i) landmark-based transformation, and (ii) object-based transformation that makes use of eye ball contour information on CT and US images.

Endoleak and in-stent thrombus detection with CT angiography in a thoracic aortic aneurysm phantom at different tube energies using filtered back projection and iterative algorithms.

PURPOSE: To determine the lower limit of dose reduction with hybrid and fully iterative reconstruction algorithms in detection of endoleaks and in-stent thrombus of thoracic aorta with computed tomographic (CT) angiography by applying protocols with different tube energies and automated tube current modulation. MATERIALS AND METHODS: The calcification insert of an anthropomorphic cardiac phantom was replaced with an aortic aneurysm model containing a stent, simulated endoleaks, and an intraluminal thrombus. CT was performed at tube energies of 120, 100, and 80 kVp with incrementally increasing noise indexes (NIs) of 16, 25, 34, 43, 52, 61, and 70 and a 2.5-mm section thickness. NI directly controls radiation exposure; a higher NI allows for greater image noise and decreases radiation. Images were reconstructed with filtered back projection (FBP) and hybrid and fully iterative algorithms. Five radiologists independently analyzed lesion conspicuity to assess sensitivity and specificity. Mean attenuation (in Hounsfield units) and standard deviation were measured in the aorta to calculate signal-to-noise ratio (SNR). Attenuation and SNR of different protocols and algorithms were analyzed with analysis of variance or Welch test depending on data distribution. RESULTS: Both sensitivity and specificity were 100% for simulated lesions on images with 2.5-mm section thickness and an NI of 25 (3.45 mGy), 34 (1.83 mGy), or 43 (1.16 mGy) at 120 kVp; an NI of 34 (1.98 mGy), 43 (1.23 mGy), or 61 (0.61 mGy) at 100 kVp; and an NI of 43 (1.46 mGy) or 70 (0.54 mGy) at 80 kVp. SNR values showed similar results. With the fully iterative algorithm, mean attenuation of the aorta decreased significantly in reduced-dose protocols in comparison with control protocols at 100 kVp (311 HU at 16 NI vs 290 HU at 70 NI, P ≤ .0011) and 80 kVp (400 HU at 16 NI vs 369 HU at 70 NI, P ≤ .0007). CONCLUSION: Endoleaks and in-stent thrombus of thoracic aorta were detectable to 1.46 mGy (80 kVp) with FBP, 1.23 mGy (100 kVp) with the hybrid algorithm, and 0.54 mGy (80 kVp) with the fully iterative algorithm.

Decomposição e liberação de N, P e K de esterco bovino e de cama de frango isolados ou misturados

A utilização de resíduos orgânicos de origem animal na adubação das culturas demanda informações sobre a dinâmica de decomposição e mineralização de nutrientes neles contidos. Este trabalho objetivou avaliar a decomposição e a liberação de N, P e K dos resíduos orgânicos esterco bovino e cama de frango isolados ou misturados, em Argissolo Vermelho-Amarelo, da região de Tabuleiros Costeiros paraibanos. O experimento foi conduzido em delineamento experimental de blocos casualizados, utilizando-se o método das sacolas de decomposição (litterbag), com os tratamentos arranjados em esquema fatorial 3 × 2 × 6, referentes a três resíduos orgânicos: esterco bovino (EB), cama de frango (CF) e a mistura desses resíduos na proporção de 1:1, denominada de esterco misto (EM); duas camadas de incorporação (0-10 e 10-20 cm); e seis períodos de avaliação (0, 30, 90, 150, 210 e 270 dias após a aplicação - DAA) com três repetições. Os resultados revelaram que a profundidade de incorporação não influenciou a decomposição dos resíduos EB e EM, que essa foi mais rápida na CF (0,0035 g dia-1), mais lenta no EB (0,0010 g dia-1) e ocorreu numa velocidade intermediária no EM (0,0020 g dia-1). Houve liberação mais rápida de N no EM (0,0011 g dia-1), de P no EB (0,0040 g dia-1) e de K na CF (0,0025 g dia-1), com tendência de aumento na liberação de N na CF e de P em todos os resíduos com a incorporação desses na camada de 10-20 cm. Após 270 DAP, estimou-se que a liberação de nutrientes pelos resíduos EB, CF e EM, em relação ao teor inicial, foi de 5,0; 15,0; e 28,0 %, para N; 80,0; 68,0; e 47,0 %, para P; e 20,0; 53,0; e 32,0 %, para K. Em valores absolutos, esses percentuais representaram, respectivamente, 19,0; 103,5; e 149,5 kg ha-1 de N; 28,0; 18,0; e 15,0 kg ha-1 de P; e 75,0; 493,0; e 209,0 kg ha-1 de K. Os resíduos orgânicos se evidenciaram fontes inadequadas para suprir isoladamente a demanda nutricional de culturas de ciclo curto nesses solos.

L'anthropologie clinique au carrefour des psychothérapies

Dans le contexte de morcellement du champ psychothérapeutique, la tendance à la spécialisation technique, ainsi qu'à la disqualification mutuelle des différents courants, fait parfois oublier l'objet même de la psychothérapie, à savoir, l'être humain en souffrance. Plus que jamais, il apparaît donc nécessaire, pour le devenir d'une psychothérapie à visage humain, que tout thérapeute prenne conscience de la portée et de la limite de l'approche à laquelle il prête obédience, relativement aux autres courants : il est ainsi invité au double travail de clarification épistémologique sur les présupposés implicites à sa théorie et méthode, et de distanciation affective à l'égard du courant théorique auquel il est rattaché. L'anthropologie clinique d'inspiration phénoménologique apporte les outils indispensables à un tel travail.

IL28B polymorphisms predict response to therapy among chronic hepatitis C patients with HCV genotype 4.

Summary.  Genetic polymorphisms near IL28B are associated with spontaneous and treatment-induced clearance of hepatitis C virus (HCV). Our objective was to assess the predictive value of IL28B polymorphisms in the treatment of chronic hepatitis C of patients with HCV genotypes 4, for which data are currently limited. We analysed the association of IL28B polymorphisms with the virological response to treatment among 182 naïve chronic hepatitis C patients with HCV genotype 4, all from Syria. Associations of alleles with the response patterns were evaluated by univariate analysis and multivariate logistic regression, accounting for all relevant covariates. Sustained virological response (SVR) was achieved in 26% of rs8099917 TG/GG carriers compared with 60% of TT carriers (P < 0.0001) and 35% of rs12979860 CT/TT carriers compared with 62% of CC carriers (P = 0.0011). By multivariate analysis, the association between rs8099917 and SVR remained significant (OR = 0.19, 95% CI 0.07-0.50, for TG/GG vs TT, P = 0.0007), with the only significant covariate being advanced fibrosis (OR = 0.13, 95% CI 0.04-0.37, P = 0.0002). In conclusion, IL28B polymorphisms are the strongest predictors of response to therapy among chronic hepatitis C patients with HCV genotype 4.
