Background:Borderline resectable pancreatic cancer may require extended resections in order to achieve tumor-free margins,especially in the case of up-front resections,but it is important to know the limits of surgical therapy in this *** study aimed to investigate the impact of extent of pancreatic and venous resection on short-and long-term outcomes in patients with pancreatic adenocarcinoma(PDAC).Methods:This was a retrospective study from a prospectively maintained database of pancreatic resections for ***-and long-term outcomes were analyzed in patients having borderline resectable PDAC submitted to up-front total pancreatectomy(TP)or pancreaticoduodenectomy(PD)with simultaneous portal vein(PV)and/or superior mesenteric vein(SMV)*** resections were carried out as tangential venous resection(TVR)or segmental venous resection(SVR).Patients were divided into 4 groups:(1)PD+TVR,(2)PD+SVR,(3)TP+TVR,(4)TP+***-and multivariate Cox regression analysis were performed to identify factors associated with ***:Ninety-nine patients were submitted to simultaneous pancreatic and venous resection for *** them,25 were submitted to PD+TVR(25.3%),12 to PD+SVR(12.1%),23 to TP+TVR(23.2%),and 39 to TP+SVR(39.4%).Overall,major morbidity(Clavien-Dindo grade≥IIIA)was 26.3%.Thirty-and 90-day mortality were 3%and 11.1%,*** were no significant differences among groups in terms of short-term *** overall survival of patients submitted to PD+TVR was significantly higher than those to TP+SVR(29.5 vs 7.9 months,P=0.001).Multivariate analysis identified TP(HR=2.11;95%CI:1.31–3.44;P=0.002)and SVR(HR=2.01;95%CI:1.27–3.15;P=0.003)as the only independent prognostic factors for overall ***:Up-front TP associated to SVR was predictive of worse survival in borderline resectable *** treatments in high-risk surgical groups may improve such poor outcomes.

Prognostic criteria for postoperative mortality in 170 patients undergoing major right hepatectomy

BACKGROUND: Postoperative hepatic failure is a dreadful complication after major hepatectomy and carries high morbidity and mortality rates. In this study, we assessed the accuracy of the 50/50 criteria (bilirubin >2.9 mg/dL and international normalized ratio >1.7 on postoperative day 5) and the Mullen criteria (bilirubin peak >7 mg/dL on postoperative days 1-7) in predicting death from hepatic failure in patients undergoing right hepatectomy only. In addition, we identified prognostic factors linked to intra-hospital morbidity and mortality in these patients. METHODS: One hundred seventy consecutive patients underwent major right hepatectomy at a tertiary medical center from 2000 to 2008. Nineteen (11.2%) patients suffered from liver cirrhosis. Univariate and multivariate analyses were performed to identify predictors of intra-hospital mortality, morbidity and death from hepatic failure. RESULTS: The intra-hospital mortality was 6.5% (11/170). Of the six patients who died from hepatic failure, one was positive for the 50/50 criteria, but all six patients were positive for the Mullen criteria. Multivariate analysis showed that male gender, hepatitis C (HCV), hepatocellular carcinoma, postoperative bilirubin >7 mg/dL and ALT65 years, HCV, reoperation, andrenal failure were significant predictors of overall intra-hospital mortality on multivariate analysis. CONCLUSIONS: The Mullen criteria were more accurate than the 50/50 criteria in predicting death from hepatic failure in patients undergoing right hepatectomy. A bilirubin peak >7 mg/dL in the postoperative period, HCV positivity, hepatocellular carcinoma, and an ALT level <188 U/L on postoperative day 1 were associated with death from hepatic failure in our patient population.

AIM: To summarize the current knowledge about the potential relationship between hepatitis C virus(HCV) infection and the risk of several extra-liver cancers. METHODS: We performed a systematic review of the literature, according to the Preferred Reporting Items for Systematic reviews and Meta-Analysis(PRISMA) Statement. We extracted the pertinent articles, published in MEDLINE and the Cochrane Library, using the following search terms: neoplasm/cancer/malignancy/tumor/carcinoma/adeno-carcinoma and non-Hodgkin lymphomas, kidney/renal-, cholangio-, pancreatic-, thyroid-, breast-,oral-, skin-, prostate-, lung-, colon-, stomach-, haematologic. Case series, case-series with control-group, case-control, cohort-studies as well as meta-analyses, written in English were collected. Some of the main characteristics of retrieved trials, which were designed to investigate the prevalence of HCV infection in each type of the above-mentioned human malignancies were summarised. A main table was defined and included a short description in the text for each of these tumours, whether at least five studies about a specific neoplasm, meeting inclusion criteria, were available in literature. According to these criteria, we created the following sections and the corresponding tables and we indicated the number of included or excluded articles, as well as of meta-analyses and reviews:(1) HCV and haematopoietic malignancies;(2) HCV and cholangiocarcinoma;(3) HCV and pancreatic cancer;(4) HCV and breast cancer;(5) HCV and kidney cancer;(6) HCV and skin or oral cancer; and(7) HCV and thyroid cancer. RESULTS: According to available data, a clear correlation between regions of HCV prevalence and risk of extra-liver cancers has emerged only for a very small group of types and histological subtypes of malignancies. In particular, HCV infection has been associated with:(1) a higher incidence of some B-cell Non-HodgkinLymphoma types, in countries, where an elevated prevalence of this pathogen is de

Aim of the present review is to summarize the current knowledge about the potential relationship between mi RNAs and hepatitis B virus(HBV)-hepatitis C virus(HCV) related liver diseases. A systematic computerbased search of published articles, according to the Preferred Reporting Items for Systematic reviews and Meta-Analysis Statement, was performed to identify relevant studies on usefulness of serum/plasma/urine mi RNAs, as noninvasive biomarkers for early detection of HBV and HCV-induced hepatocellular carcinoma(HCC) development, as well as for its prognostic evaluation. The used Medical Subject Headings terms and keywords were: "HBV", "HCV", "hepatocellular carcinoma", "micro RNAs", "mi RNAs", "diagnosis", "prognosis", "therapy", "treatment". Some serum/plasma mi RNAs, including mi R-21, mi R-122, mi-125a/b, mi R-199a/b, mi R-221, mi R-222, mi R-223, mi R-224 might serve as biomarkers for early diagnosis/prognosis of HCC, but, to date, not definitive results or well-defined panels of mi RNAs have been obtained. More well-designed studies, focusing on populations of different geographical areas and involving larger series of patients, should be carried out to improve our knowledge on the potential role of mi RNAs for HCC early detection and prognosis.

Frontiers of physics 2016年第1期11卷 1-15页

作者： matteo Rama Sezione di Pisa dell'Istituto Nazionale di Fisica Nucleate Pisa Italy

We review the measurements of the D decay strong-phase parameters based on quantum-correlated D^0D^-0 pairs produced in the e^＋e^→（3770） →D^0D^-0 process, and we discuss their role in the measurements of Cabibbo-Kobayashi-Maskawa angle 7 and D-/9 mixing. In addition, we present estimates of the size of quantum-correlated datasets necessary to support the 7 and charm mixing measurements conducted at the LHCb and Belle Ⅱ experiments. Finally, we review the methods for measuring the D-D^- mixing and cP violation parameters at a high-luminosity charm factory, giving sensitivity estimates.

Hepatic effector CD8＋ T-cell dynamics

引用

Cellular & Molecular Immunology 2015年第3期12卷 269-272页

作者： matteo Iannacone Division of Immunology Transplantation and Infectious Diseases I RCCS San Raffaele Scientific Institute and Vita-Saiute San Raffaele University Milan Italy

CD8＋ T cells play a critical role in hepatitis B virus （HBV） pathogenesis. During acute, self-limited infections, these cells are instrumental to viral clearance; in chronic settings, they sustain repetitive cycles of hepatocellular necrosis that promote hepatocellular carcinoma development. Both CD8＋ T-cell defensive and destructive functions are mediated by antigen-experienced effector cells and depend on the ability of these cells to migrate to the liver, recognize hepatocellular antigens and perform effector functions. Understanding the signals that modulate the spatiotemporal dynamics of CD8＋ T cells in the liver, particularly in the context of antigen recognition, is therefore critical to gaining insight into the pathogenesis of acute and chronic HBV infection. Here, we highlight recent data on how effector CD8＋ T cells traffic within the liver, and we discuss the potential for novel imaging techniques to shed light on this important aspect of HBV pathogenesis.
