Treatment of Relapse after Allogeneic Hematopoietic Stem Cell Transplantation with Venetoclax, Hypomethylating Agents and DLI - a Retrospective Multi…
2019
Introduction: The most common cause of treatment failure after allogeneic hematopoetic stem cell transplantation (aHSCT) is relapse. The combination of venetoclax and the hypomethylating agents (HMA) azacitidine (AZA) or decitabine (DAC) have shown promising efficacy in elderly patients with AML. We here present clinical data on 32 patients, who were treated with an HMA/venetoclax combination therapy (HMAClax) for relapse of a myeloid malignancy after aHSCT, collected retrospectively from 11 German centers. Results: Sixteen patients (50%) were male, median age was 54 years (30.8-71.5). Diagnoses at aHSCT were 25 AML (17 primary, 8 emerging from MDS, CMML or OMF), 5 MDS, 1 CMML and one atypi…
Pleuropulmonary Changes Induced by Drugs in Patients with Hematologic Diseases
2010
Patients with hematologic diseases who are being treated with therapy drugs, or receive radiation therapy or blood transfusions may develop a host of potentially fatal infectious and noninfectious pulmonary complications [1]. The increased complexity of multimodality and high-dose treatment regimens with the intended benefit of augmented antineoplastic efficacy and prolonged disease-free survival, the use of a panel of novel drugs to treat malignant and nonmalignant hematologic conditions (e.g., azacytidine, bortezomib, cladribine, dasatinib, fludarabine, imatinib, lenalidomide, rituximab, and thalidomide), total body irradiation (TBI) and hematopietic stem cell transplantation (HSCT) have …
Elotuzumab in Combination with Lenalidomide, Bortezomib, Dexamethasone and Autologous Transplantation for Newly-Diagnosed Multiple Myeloma: Results f…
2021
Abstract Background: Treatment regimens including a proteasome inhibitor, immunomodulating agent and a monoclonal antibody (moAb) play an emerging role in the treatment of newly-diagnosed multiple myeloma (NDMM). This multicenter phase III trial of the German-speaking Myeloma Multicenter Group (GMMG HD6) investigated the addition of the anti-SLAMF7 moAb elotuzumab to lenalidomide / bortezomib / dexamethasone (RVd) in induction and consolidation therapy as well as to lenalidomide maintenance treatment in transplant-eligible NDMM. Patients and Methods: Patients were equally randomized into four treatment arms, stratified by International Staging System (ISS). Treatment consisted of four 21-da…
Tafasitamab Plus Lenalidomide Versus Pola-BR, R2, and CAR T: Comparing Outcomes from RE-MIND2, an Observational, Retrospective Cohort Study in Relaps…
2021
Abstract Background Several therapies are recommended by NCCN/ESMO guidelines for autologous stem cell transplant (ASCT)-ineligible patients with relapsed/refractory (R/R) diffuse large B-cell lymphoma (DLBCL). In the single-arm, Phase II L-MIND study (NCT02399085), the chemotherapy-free regimen tafasitamab + lenalidomide (LEN) demonstrated efficacy for this patient population. In the absence of randomized clinical trial data, RE-MIND2 (NCT04697160), an observational, retrospective cohort study, compared patient outcomes from L-MIND with matched patient populations treated with NCCN/ESMO recommended therapies for ASCT-ineligible patients with R/R DLBCL. Methods Data were retrospectively col…
Network meta-analysis of randomized trials in multiple myeloma: efficacy and safety in relapsed/refractory patients.
2017
Despite major therapeutic advancements, multiple myeloma (MM) is still incurable and relapsed/refractory multiple myeloma (RRMM) remains a challenge; the rational choice of the most appropriate regimen in this setting is currently undefined. We performed a systematic review and 2 standard pairwise meta-analyses to evaluate the efficacy of regimens that have been directly compared with bortezomib or immunomodulatory imide drugs (IMiDs) in head-to-head clinical trials and a network meta-analysis (NMA) to determine the relevance of each regimen on the basis of all the available direct and indirect evidence. Sixteen trials were included in the pairwise meta-analyses, and 18 trials were included…
El desarrollo de la organización consciente en equipos: un clima de participación no basta, los equipos necesitan sentir seguridad para realizar prop…
2020
Mindful organizing (also known as collective mindfulness) is a collective capability that allows teams to anticipate and swiftly recover from unexpected events. This collective capability is especially relevant in high-risk environments where reliability in performance is of utmost importance. In this paper, we build on current mindful organizing theory by showing how two front-line communication and participatory conditions (perceived safety for upward dissent and climate for employee engagement) interact to predict mindful organizing. We shed light on the controversy around mindful organizing’s effect on team’s subjective experience at work by showing that it leads to greater …
CORRELATED BIOCHEMICAL AND ULTRASTRUCTURAL CHANGES IN NITROGEN-STARVED EUGLENA GRACILIS1
1996
Growth of Euglena gracilis Z Pringsheim under photoheterotrophic conditions in a nitrogen-deprived medium resulted in progressive loss of chloroplastic material until total bleaching of the cells occurred. Biochemical analysis and ultrastructural observation of the first stages of the starvation process demonstrated an early lag phase (from 0 to 9 h) in which cells increased in size, followed by a period of cell division, apparently supported by the mobilization of some chloroplastic proteins such as the photosynthetic CO2-fixing enzyme ribulose-1,5-bisphosphate carboxylase/oxygenase. The degradation of the enzyme started after 9 h of starvation and was preceded by a transient concentration…
Modification of the proteolytic fragmentation pattern upon oxidation of cysteines from ribulose 1,5-bisphosphate carboxylase/oxygenase.
2003
The proteolytic susceptibility of the native CO 2 -fixing photosynthetic enzyme ribulose 1,5-bisphosphate carboxylase/oxygenase (EC 4.1.1.39, Rubisco) has been shown to increase in vitro after oxidative treatments that affect cysteine thiols. A limited incubation of oxidized (pretreated with the disulfide cystamine) Rubisco from Chlamydomonas reinhardtii with subtilisin or proteinase K generated fragments of molecular mass about 53 kDa (band I in SDS-PAGE) and 47 kDa (band II) derived from the large subunit (55 kDa) of the enzyme. In contrast, proteolysis of the reduced Rubisco (pretreated with the free thiol cysteamine) produced only the 53 kDa band. The same fragmentation pattern was repr…
Oxidative modification and breakdown of ribulose-1,5-bisphosphate carboxylase/oxygenase induced in Euglena gracitis by nitrogen starvation
1994
When photoheterotrophic Euglena gracilis Z Pringsheim was subjected to nitrogen (N)-deprivation, the abundant photosynthetic enzyme ribulose-1,5-bis-phosphate carboxylase/oxygenase (Rubisco; EC 4.1.1.39) was rapidly and selectively degraded. The breakdown began after a 4-h lag period and continued for a further 8 h at a steady rate. After 12 h of starvation, when the amount of Rubisco was reduced to 40%, the proteolysis of this enzyme slowed down while degradation of other proteins started at a similar pace. This resulted in a decline of culture growth, chloroplast disassembly — as witnessed by chlorophyll (Chl) loss — and cell bleaching. Experiments with spectinomycin, an inhibitor of chlo…
Pittura del XIX e del XX secolo nel segno del collezionismo siciliano
2020
Il volume offre una ricognizione sul collezionismo in Sicilia e prende in esame, per la prima volta nella sua interezza, una collezione privata proponendo la riscoperta di opere di autori rappresentativi della cultura figurativa italiana del XIX e del XX secolo, tra cui Michele Catti, Ettore De Maria Bergler, Onofrio Tomaselli, Pippo Rizzo, Alfonso Amorelli e Pina Calì. La collezione privilegia la pittura dell’isola ma include anche il pittore non siciliano Giuseppe Amisani e la coppia di bronzi di Antonio Ugo e trova nelle opere "Costumi" di Salvatore Lo Forte del 1839 e "Sogno del carabiniere" di Pippo Rizzo degli anni ’50 i propri limiti cronologici. Questa raccolta privata, per lo più i…
