Thrombophilic genetic factors PAI-1 4G-4G and MTHFR 677TT as risk factors of alcohol, cryptogenic liver cirrhosis and portal vein thrombosis, in a Ca…
2015
The thrombophilic genetic factors (THRGFs), PAI-1 4G-4G, MTHFR 677TT, V Leiden 506Q and Prothrombin 20210A, were studied as risk factors in 865 Caucasian patients with liver cirrhosis, consecutively enrolled from June 2008 to January 2014. A total of 582 HCV, 80 HBV, 94 alcohol, (82 with more than one etiologic factor) and 191 cryptogenic patients with liver cirrhosis had been consecutively enrolled; 243 patients showed portal vein thrombosis (PVT). At least one of the above THRGFs was present in 339/865 patients (39.2%). PAI-1 4G-4G and MTHFR 677TT were the most frequent THRGFs, statistically significant in patients with alcohol, cryptogenic liver cirrhosis, and PVT: respectively 24 and 28…
Comportamiento periodontal de restauraciones de recubrimiento completo sobre preparaciones dentarias sin línea de terminación: Estudio clínico prospe…
2020
La estabilidad de los tejidos gingivales es uno de los retos para la rehabilitación estética con prótesis fija. La técnica de preparación BOPT es un protocolo en el cual se elimina la emergencia de la corona anatómica dental y la línea de terminación preexistente. La experiencia clínica mediante esta técnica, ha demostrado producir un aumento del grosor gingival y generar una mejor estabilidad de los tejidos blandos a medio y largo plazo. Objetivo: Evaluar el comportamiento clínico y biológico de las restauraciones de recubrimiento total en dientes preparados sin línea de terminación durante un seguimiento de 6 años. Material y Métodos: Este estudio prospectivo incluyó 149 dientes tratados …
Genome- wide association study with additional genetic and post-transcriptional analyses reveals novel regulators of plasma factor XI levels
2017
International audience; Coagulation factor XI (FXI) has become increasingly interesting for its role in pathogenesis of thrombosis. While elevated plasma levels of FXI have been associated with venous thromboembolism and ischemic stroke, its deficiency is associated with mild bleeding. We aimed to determine novel genetic and post-transcriptional plasma FXI regulators.We performed a genome-wide association study (GWAS) for plasma FXI levels, using novel data imputed to the 1000 Genomes reference panel. Individual GWAS analyses, including a total of 16,169 European individuals from the ARIC, GHS, MARTHA and PROCARDIS studies, were meta-analysed and further replicated in 2,045 individuals from…
Tissue factor pathway inhibitor primes monocytes for antiphospholipid antibody-induced thrombosis
2019
Antiphospholipid antibodies (aPLs) with complex lipid and/or protein reactivities cause complement-dependent thrombosis and pregnancy complications. Although cross-reactivities with coagulation regulatory proteins contribute to the risk for developing thrombosis in patients with antiphospholipid syndrome, the majority of pathogenic aPLs retain reactivity with membrane lipid components and rapidly induce reactive oxygen species-dependent proinflammatory signaling and tissue factor (TF) procoagulant activation. Here, we show that lipid-reactive aPLs activate a common species-conserved TF signaling pathway. aPLs dissociate an inhibited TF coagulation initiation complex on the cell surface of m…
Antiphospholipid antibodies in pediatric patients with prolonged activated partial thromboplastin time during infection.
2005
Abstract Objective To investigate the close association between different antiphospholipid antibodies (aPL) caused by infection and their appearance together with a prolonged activated partial thromboplastin time (aPTT). Methods Sera from 122 children were evaluated in this study. Thirty-seven children with mild to medium prolonged aPTT (>37.2 s) and elevated C-reactive protein (CRP) levels during various forms of infections (group 2), 18 children without infections (group 3) but with mild to medium prolonged aPTT and 13 children with infections (group 4) and with elevated CRP-level as well as a control group (group 1) of 54 patients without any infection and normal aPTT and negative CRP le…

Comparison between thrombotic risk scores in essential thrombocythemia and survival implications.
2019
The conventional thrombotic risk stratification in essential thrombocythemia (ET) distinguishes patients in two risk groups based on previous thrombosis and age (< or >60). The IPSET-thrombosis takes into account four risk factors: age greater than 60 years and the presence of CV risk factors, thrombosis history and JAK2 V617F presence. The revised IPSET-thrombosis uses three adverse variables to delineate four risk categories: age greater than 60, thrombosis history, and JAK2 V617F presence. We compared different risk models in the estimation of thrombotic risk in 191 patients with ET and the role of specific driver mutations affecting overall survival, according to thrombotic risk. …
Enhanced radiosensitivity in experimental tumours following erythropoietin treatment of chemotherapy-induced anaemia.
1998
The radiosensitivity of solid tumours in anaemic rats treated with recombinant human erythropoietin (rhEPO, epoetin beta) was studied. Anaemia was induced by a single dose of carboplatin (45 mg kg(-1) i.v.), resulting in a reduction in the haemoglobin concentration by 30%. In a second group, the development of anaemia was prevented by rhEPO (1000 IU kg(-1)) administered s.c. three times per week starting 6 days before the carboplatin application. Three days after carboplatin treatment, DS-sarcomas were implanted subcutaneously onto the hind foot dorsum. Neither carboplatin nor rhEPO treatment influenced tumour growth rate. Five days after implantation, tumours were irradiated with a single …

Malignant germ cell tumors in childhood: results of the first Italian cooperative study "TCG 91".
2003
Background and Aims About 20% of patients with germ cell tumor (GCT) are still resistant to therapy. To investigate which features are present in resistant patients, a multicenter study on GCT in children was undertaken to correlate clinical and laboratory parameters with the outcome. Methods Patients aged less than 16 years, with histologically proven extracranial GCT were included. Results Ninety-five patients (median age 33 months, 45 males) were eligible. The site of the primary tumor was gonadal in 59, extragonadal in 36. The stage was I in 39; II in 5; IIIa (microscopic residue) in 7; IIIb (macroscopic residue) in 16; IIIc (unresectable) in 13; IV in 15. The treatment was surgery alon…
