Knowledge and attitudes towards smoking cessation counselling: an Italian cross-sectional survey on tertiary care nursing staff
2021
Background One of the most effective smoking cessation strategies involves care and advice from nurses due to their role in the front line of treatment. Lack of education on smoking cessation counselling may be detrimental, and adequate smoking cessation training during healthcare studies is needed. Objectives The study aimed to examine nurses’ attitudes, belief, and knowledge of smoking cessation counselling; knowledge of the health risks associated with smoking was also assessed. Design A cross-sectional survey on 77 nurses from the nursing staff of Cardiology, Cardiac Intensive Care and Surgical Oncology Units of two tertiary hospitals. Methods Cronbach’s alpha was calculated to assess …
Immunochemotherapy with Fludarabine (F), Cyclophosphamide (C), and Rituximab (R) (FCR) Versus Fludarabine and Cyclophosphamide (FC) Improves Response…
2008
Abstract Introduction: Previous phase II studies have suggested that a combination of FCR may increase the outcome of both untreated and relapsed CLL pts. In order to validate this concept the German CLL study group (GCLLSG) initiated a multicentre, multinational phase III trial, CLL8, to evaluate the efficacy and tolerability of FCR versus FC for the first-line treatment of pts with advanced CLL. Methods and Patients: 817 pts with good physical fitness as defined by a cumulative illness rating scale (CIRS) score (Extermann et al., JCO 1998) of up to 6 and a creatinine clearance (cr cl) □d 70 ml/min were enrolled between July 2003 and March 2006. Pts were randomly assigned to receive 6 cour…
Efficacy of Caplacizumab in Patients with aTTP in the HERCULES Study According to Initial Immunosuppression Regimen
2019
Background: Acquired thrombotic thrombocytopenic purpura (aTTP) is an acute, life-threatening thrombotic microangiopathy that requires urgent and specialized treatment. Prior to the introduction of caplacizumab, the treatment for aTTP was based on daily therapeutic plasma exchange (TPE; to replenish functional ADAMTS13 enzyme) plus immunosuppression (mainly corticosteroids and rituximab; to suppress anti-ADAMTS13 autoantibody production). TPE combined with immunosuppressive therapy improved outcomes in patients; however, episodes of aTTP are still associated with an acute mortality of up to 20% as these therapies do not have an immediate effect on the pathologic microvascular thrombosis. Th…
First-Line Treatment with Fludarabine (F), Cyclophosphamide (C), and Rituximab (R) (FCR) Improves Overall Survival (OS) in Previously Untreated Patie…
2009
Abstract Abstract 535 Introduction: In 2008, first results of a multicenter, international randomized phase III trial (CLL8) were presented, showing superiority of FCR chemoimmunotherapy for response rates and progression-free survival (PFS) when compared to FC chemotherapy. We now report updated results with a longer median observation time of 37.7 months (mo). Methods and Patients: 817 treatment-naïve patients (pts) with good physical fitness and CD20-positive CLL randomly (1:1) received treatment with 6 courses of either FCR or FC therapy. Both treatment arms were well balanced with regard to sex, age, stage, genomic aberrations and IGVH gene status. The median age was 61 years (range 3…
Y-90 Ibritumomab Tiuxetan as Consolidation Following Three Cycles of Fludarabine-Cyclophosphamide-Rituximab Chemoimmunotherapy in Patients with Relap…
2007
Abstract BACKGROUND: Tumed sequential treatment with fludarabine/cyclophosphamide/rituximab (FC-R) followed by Y-90 ibritumomab tiuxetan (IT) radioimmunotherapy may improve progression-free survival in patients (pts) with CD20+ NHL. However, even unpretreated pts submitted to four to six cycles of a fludarabine-containing combination and then IT at an Y-90 activity of 15 MBq/kg will experience severe prolonged, transfusion-dependent and only partially reversible pancytopenia, thus limiting its use in a non-curative setting (Jurczak et al., ASH 2005). AIM: We report on a trial including anthracycline-pretreated pts with relapsing CD20+ lymphoma > age 50 and unsuitable for myeloablative tr…
Allogeneic stem cell transplantation after conditioning with treosulfan, etoposide and cyclophosphamide for patients with acute lymphoblastic leukemi…
2014
Abstract Total-body-irradiation (TBI) based preparative regimens are considered as standard conditioning therapy for allogeneic stem cell transplantation (AHSC) in patients with acute lymphoblastic leukemia (ALL). Within a multi-center prospective phase II study we have investigated the toxicity and efficacy of a non-TBI-based regimen consisting of treosulfan, etoposide, and cyclophosphamide in patients with ALL. Inclusion criteria were complete remission, non-eligibility for TBI or patient’s wish to avoid TBI. Between July 2007 and August 2010, 50 patients with a median age of 46.5 years were enrolled at ten German centers. 74% of the patients were in 1. CR and 26% 2. or higher CR.The cond…
18-hydroxylation in the Y-1 adrenal cell line: response to ACTH and to culture conditions.
1992
The 18-hydroxylation of deoxycorticosterone in the Y-1 adrenal cell line was studied under various incubation and cell culture conditions and compared to 11 beta-hydroxylation. Repeated incubation of the substrate increased both 18- and 11 beta-hydroxylation in the Y-1 cells. Furthermore, both 18- and 11 beta-hydroxylation were increased with increased serum concentration and prolonged incubation time. While the increase in 11 beta-hydroxylation seemed to be independent of the type of serum, 18-hydroxylation was much more important in cells cultured in fetal or newborn calf serum supplemented medium than in those cultured in horse serum supplemented medium. As expected, ACTH treatment incre…
Splenic Marginal Zone Lymphoma: French Registries Population-Based Treatment and Survival Analyses (2002-2014)
2020
Background. Splenic Marginal Zone Lymphoma (SMZL) is a rare indolent B-cell lymphoma characterized by a massive splenomegaly and a moderate lymphocytosis. There is no standard of care for SMZL so far. The treatment is indicated if constitutional symptoms, massive splenomegaly and/or cytopenia, after a watch and wait period that is highly variable. Rituximab with or without chemotherapy, chemotherapy, and splenectomy are valid treatment approaches. Our objectives were to describe the characteristics of the patients with SMZL retrospectively collected from a French population database, to analyze the treatments received in first line (Tt1) and in second line (Tt2) in term of efficacy, and to …
Ruxolitinib Plus Pomalidomide in Myelofibrosis: Updated Results from the Mpnsg-0212 Trial (NCT01644110)
2016
Abstract Background: Although ruxolitinib (RUX) reduces constitutional symptoms and splenomegaly in myelofibrosis (MF) therapy options for anemia are limited. In our prior MPNSG-0109 trial of pomalidomide (POM) in MF with cytopenia, anemia responses were reported in 14% and 29% of subjects receiving POM 0.5 mg/d and 2 mg/d, respectively (Schlenk RF et al., ASH 2013, abstract #2822). We designed a phase-Ib/-II combination study of RUX plus POM to evaluate synergistic effects in subjects with anemia and splenomegaly (MPNSG-0212 trial, NCT01644110; Stegelmann et al., ASH 2015, abstract #826). Study Design: Primary endpoints are response rate after 12 treatment cycles (28 days each) according t…
Sjøgren's syndrome-associated oxidative stress and mitochondrial dysfunction: Prospects for chemoprevention trials
2012
An involvement of oxidative stress (OS) was found in recent studies of Sjøgren's syndrome (SS) that reported significant changes in protein oxidation, myeloperoxidase activity, TNF-α, nitrotyrosine, and GSH levels in plasma from SS patients. Excess levels of OS markers, as oxidative DNA damage and propanoyl-lysine, were reported in saliva from SS patients. Previous reports concurred with a role of OS in SS pathogenesis, by showing a decreased expression of antioxidant activities in conjunctival epithelial cells of SS patients and in parotid gland tissue samples from SS patients. A link between OS and mitochondrial dysfunction (MDF) is recognized both on the grounds of the established role o…
