All-Cause Mortality and Liver-Related Outcomes Following Successful Antiviral Treatment for Chronic Hepatitis C

BACKGROUND: Antiviral therapy for the hepatitis C virus (HCV) reduces all-cause and liver-related morbidity and mortality. Few studies are available from populations with multiple medical and psychiatric comorbidities where the impact of successful antiviral therapy might be limited. AIM: The purpose of this study was to determine the effect of sustained virologic response (SVR) on all-cause and liver-related mortality in a cohort of HCV patients treated in an integrated hepatitis/mental health clinic. METHODS: This was a retrospective review of all patients who initiated antiviral treatment for chronic HCV between January 1, 1997 and December 31, 2009. Cox regression analysis was used to determine factors involved in all-cause mortality, liver-related events and hepatocellular carcinoma. RESULTS: A total of 536 patients were included in the analysis. Median follow-up was 7.5 years. Liver and non-liver-related mortality occurred in 2.7 and 5.0 % of patients with SVR and in 17.8 and 6.4 % of patients without SVR. In a multivariate analysis, SVR was the only factor associated with reduced all-cause mortality (HR 0.47; 95 % CI 0.26-0.85; p = 0.012) and reduced liver-related events (HR 0.23; 95 % CI 0.08-0.66, p = 0.007). Having stage 4 liver fibrosis increased all-cause mortality (HR 2.50; 95 % CI 1.23-5.08; p = 0.011). Thrombocytopenia at baseline (HR 2.66; 95 % CI 1.22-5.79; p = 0.014) and stage 4 liver fibrosis (HR 4.87; 95 % CI 1.62-14.53; p = 0.005) increased liver-related events. CONCLUSIONS: Despite significant medical and psychiatric comorbidities, SVR markedly reduced liver-related outcomes without a significant change in non-liver-related mortality after a median follow-up of 7.5 years.

Ruler Based Automatic C-Arm Image Stitching Without Overlapping Constraint

In this paper, we propose a new method for stitching multiple fluoroscopic images taken by a C-arm instrument. We employ an X-ray radiolucent ruler with numbered graduations while acquiring the images, and the image stitching is based on detecting and matching ruler parts in the images to the corresponding parts of a virtual ruler. To achieve this goal, we first detect the regular spaced graduations on the ruler and the numbers. After graduation labeling, for each image, we have the location and the associated number for every graduation on the ruler. Then, we initialize the panoramic X-ray image with the virtual ruler, and we “paste” each image by aligning the detected ruler part on the original image, to the corresponding part of the virtual ruler on the panoramic image. Our method is based on ruler matching but without the requirement of matching similar feature points in pairwise images, and thus, we do not necessarily require overlap between the images. We tested our method on eight different datasets of X-ray images, including long bones and a complete spine. Qualitative and quantitative experiments show that our method achieves good results.

The CLIF Consortium Acute Decompensation score (CLIF-C ADs) for prognosis of hospitalised cirrhotic patients without acute-on-chronic liver failure

BACKGROUND & AIMS Cirrhotic patients with acute decompensation frequently develop acute-on-chronic liver failure (ACLF), which is associated with high mortality rates. Recently, a specific score for these patients has been developed using the CANONIC study database. The aims of this study were to develop and validate the CLIF-C AD score, a specific prognostic score for hospitalised cirrhotic patients with acute decompensation (AD), but without ACLF, and to compare this with the Child-Pugh, MELD, and MELD-Na scores. METHODS The derivation set included 1016 CANONIC study patients without ACLF. Proportional hazards models considering liver transplantation as a competing risk were used to identify score parameters. Estimated coefficients were used as relative weights to compute the CLIF-C ADs. External validation was performed in 225 cirrhotic AD patients. CLIF-C ADs was also tested for sequential use. RESULTS Age, serum sodium, white-cell count, creatinine and INR were selected as the best predictors of mortality. The C-index for prediction of mortality was better for CLIF-C ADs compared with Child-Pugh, MELD, and MELD-Nas at predicting 3- and 12-month mortality in the derivation, internal validation and the external dataset. CLIF-C ADs improved in its ability to predict 3-month mortality using data from days 2, 3-7, and 8-15 (C-index: 0.72, 0.75, and 0.77 respectively). CONCLUSIONS The new CLIF-C ADs is more accurate than other liver scores in predicting prognosis in hospitalised cirrhotic patients without ACLF. CLIF-C ADs therefore may be used to identify a high-risk cohort for intensive management and a low-risk group that may be discharged early.

Zircons, isotope ratios and element analyses from tonalite and oxide gabbro of the mid-ocean ridge from ODP Hole 176-735B

A limiting factor in the accuracy and precision of U/Pb zircon dates is accurate correction for initial disequilibrium in the 238U and 235U decay chains. The longest-lived-and therefore most abundant-intermediate daughter product in the 235U isotopic decay chain is 231Pa (T1/2 = 32.71 ka), and the partitioning behavior of Pa in zircon is not well constrained. Here we report high-precision thermal ionization mass spectrometry (TIMS) U-Pb zircon data from two samples from Ocean Drilling Program (ODP) Hole 735B, which show evidence for incorporation of excess 231Pa during zircon crystallization. The most precise analyses from the two samples have consistent Th-corrected 206Pb/238U dates with weighted means of 11.9325 ± 0.0039 Ma (n = 9) and 11.920 ± 0.011 Ma (n = 4), but distinctly older 207Pb/235U dates that vary from 12.330 ± 0.048 Ma to 12.140 ± 0.044 Ma and 12.03 ± 0.24 to 12.40 ± 0.27 Ma, respectively. If the excess 207Pb is due to variable initial excess 231Pa, calculated initial (231Pa)/(235U) activity ratios for the two samples range from 5.6 ± 1.0 to 9.6 ± 1.1 and 3.5 ± 5.2 to 11.4 ± 5.8. The data from the more precisely dated sample yields estimated DPazircon/DUzircon from 2.2-3.8 and 5.6-9.6, assuming (231Pa)/(235U) of the melt equal to the global average of recently erupted mid-ocean ridge basaltic glasses or secular equilibrium, respectively. High precision ID-TIMS analyses from nine additional samples from Hole 735B and nearby Hole 1105A suggest similar partitioning. The lower range of DPazircon/DUzircon is consistent with ion microprobe measurements of 231Pa in zircons from Holocene and Pleistocene rhyolitic eruptions (Schmitt (2007; doi:10.2138/am.2007.2449) and Schmitt (2011; doi:10.1146/annurev-earth-040610-133330)). The data suggest that 231Pa is preferentially incorporated during zircon crystallization over a range of magmatic compositions, and excess initial 231Pa may be more common in zircons than acknowledged. The degree of initial disequilibrium in the 235U decay chain suggested by the data from this study, and other recent high precision datasets, leads to resolvable discordance in high precision dates of Cenozoic to Mesozoic zircons. Minor discordance in zircons of this age may therefore reflect initial excess 231Pa and does not require either inheritance or Pb loss.

La tierra pública periurbana : Arrendamiento, enfiteusis y ventas en el entorno agrario de Buenos Aires (San Jos�� de Flores, 1800-1862)

Las distintas cuestiones vinculadas al traspaso de las tierras públicas a manos particulares (en usufructo y en propiedad plena) en la campaña bonaerense del siglo XIX han suscitado el interés de diversos investigadores que, a partir de estudios de casos mayoritariamente vinculados a la dinámica de expansión de la frontera sur, delinearon las modalidades generales del proceso. Abordando el estudio de los distintos modos de acceso a la tenencia y propiedad de la tierra, en el contexto de la venta de los terrenos fiscales situados en el entorno agrario de la ciudad de Buenos Aires, pretendemos sumar al conocimiento de esta dinámica las particularidades de un área de muy antiguo asentamiento y ocupación productiva, con una larga tradición de arrendamiento de tierras de 'pan llevar' de antigua propiedad eclesiástica y una agricultura mercantil de pequeños y medianos productores orientada al abasto urbano
