Blackberries (Rubus spp.) are among the high added value food products relevant for human health due to the increasing evidence of the beneficial effects of polyphenols, which are very abundant in these fruits. Interestingly, these compounds also play a role on plant physiology, being especially relevant their role in plant defense against biotic and abiotic stress. Hence, we hypothesize that since blackberry fruits have high amounts of flavonols and anthocyanins, leaves would also have high amounts of these compounds, and can be studied as a source of active molecules; furthermore, leaf synthesis would support their high contents in fruits...

BACKGROUND: The development of newer strategies to improve outcomes for older patients with secondary acute myeloid leukemia (s-AML) is a critical unmet need. Establishing baseline metrics for evaluating newer approaches is important. METHODS: s-AML was defined as 1 or more of the following: a history of an antecedent hematologic disorder (AHD), a diagnosis of therapy-related acute myeloid leukemia (AML), and AML with karyotype abnormalities characteristic of myelodysplastic syndrome...

Aims: Coronary artery spasm (CAS) is associated with ventricular arrhythmias (VA). Much controversy remains regarding the best therapeutic interventions for this specific patient subset. We aimed to evaluate the clinical outcomes of patients with a history of life-threatening VA due to CAS with various medical interventions, as well as the need for ICD placement in the setting of optimal medical therapy. Methods and results: A multicentre European retrospective survey of patients with VA in the setting of CAS was aggregated and relevant clinical and demographic data was analysed...

Myelodysplastic syndromes (MDSs) are characterized by ineffective hematopoiesis and an increased risk of transformation. Few effective therapies are available for lower risk MDS patients, especially after the failure of hypomethylating agents. MDS progenitor cells are dependent on the nuclear factor-κB (NF-κB) for survival, which makes it an attractive therapeutic target. As a proteosomal inhibitor, bortezomib is thought to have inhibitory activity against NF-κB. We designed a proof-of-principle study of subcutaneous (SC) bortezomib in lower risk MDS patients with evidence of NF-κB activation in their bone marrow...

Hypomethylating agents (HMA) are the most commonly used therapeutic intervention in chronic myelomonocytic leukemia (CMML). Due to the lack of CMML-specific clinical trials, the impact of these agents in the natural history of CMML is not fully understood. We present the largest retrospective series of CMML (n=151) treated with HMA. Mean age at diagnosis was 69 years (range 50-88). According to the CMML-specific prognostic scoring system (CPSS): 17 (15%) were low-risk, 45 (39%) intermediate-1 risk, 42 (36%) intermediate-2, and 12 (10%) high-risk...

Although overexpression/activation of focal adhesion kinase (FAK) is widely known in solid tumors to control cell growth, survival, invasion, metastasis, gene expression, and stem cell self-renewal, its expression and function in myeloid leukemia are not well investigated. Using reverse-phase protein arrays in large cohorts of newly diagnosed acute myeloid leukemia (AML) and myeloid dysplastic syndrome (MDS) samples, we found that high FAK expression was associated with unfavorable cytogenetics (P = 2 x 10-4) and relapse (P = 0...

Prospective data are needed to ascertain the impact of iron chelation therapy in patients with myelodysplastic syndromes. The present 5-year prospective registry analysis was conducted to compare clinical outcomes between chelated and nonchelated patients with lower-risk myelodysplastic syndromes and transfusional iron overload. In an interim analysis at 24 months, we previously reported that chelation therapy was associated with longer median overall survival and a tendency toward longer leukemia-free survival and fewer cardiac events...

In this contribution a methodology to compute and classify shear-induced structural and phase transitions in surfactant/water mixtures from rheological measurements is presented. Non-linear rheological experiments, considering variations in surfactant concentration and temperature, are analyzed. In particular, the parameters of the BMP (Bautista-Manero-Puig) model, obtained from the fitting of the shear stress versus shear rate data, which are functions of surfactant concentration and temperature, allow classifying structural and phase transition boundaries...

Internal tandem duplication (ITD) mutation in Fms-like tyrosine kinase 3 gene (FLT3/ITD) represents an unfavorable genetic change in acute myeloid leukemia (AML) and is associated with poor prognosis. Metabolic alterations have been involved in tumor progression and attracted interest as a target for therapeutic intervention. However, few studies analyzed the adaptations of cellular metabolism in the context of FLT3/ITD mutation. Here, we report that FLT3/ITD causes a significant increase in aerobic glycolysis through AKT-mediated upregulation of mitochondrial hexokinase (HK2), and renders the leukemia cells highly dependent on glycolysis and sensitive to pharmacological inhibition of glycolytic activity...

While therapy-related (t)-myelodysplastic syndromes (MDS) have worse outcomes than de novo MDS (d-MDS), some t-MDS patients have an indolent course. Most MDS prognostic models excluded t-MDS patients during development. The performances of the International Prognostic Scoring System (IPSS), revised IPSS (IPSS-R), MD Anderson Global Prognostic System (MPSS), WHO Prognostic Scoring System (WPSS) and t-MDS Prognostic System (TPSS) were compared among patients with t-MDS. Akaike information criteria (AIC) assessed the relative goodness of fit of the models...

BACKGROUND: The prognosis of patients with higher-risk myelodysplastic syndromes (MDS) remains poor despite available therapies. Histone deacetylase inhibitors have demonstrated activity in patients with MDS and in vitro synergy with azacitidine. METHODS: A phase 2 randomized, placebo-controlled clinical trial of azacitidine and pracinostat was conducted in patients who had International Prognostic Scoring System intermediate-2-risk or high-risk MDS. The primary endpoint was the complete response (CR) rate by cycle 6 of therapy...

Two hundred and sixteen consecutive patients with MDS and abnormal karyotype treated with hypomethylating agents between 4/04 and 10/12 were reviewed. Median follow-up was 17 months. Using IWG criteria, best responses were complete response (CR) in 79 patients (37%), partial response (PR) in 4 (2%), and hematologic improvement (HI) in 10 (5%). Cytogenetic response (CyR) was achieved in 78 patients (36%): complete (CCyR) in 62 (29%) and partial in 16 (7%). CyR was achieved in 48 of 79 patients (61%) with CR, 1 of 14 (7%) with PR/HI, and in 29 of the 123 (24%) with no morphologic response...

We sought to determine the significance of minimal residual disease (MRD) relapse in patients with ALL after achieving MRD negative status following induction and consolidation therapy. Between January 2003 and September 2014, 647 newly diagnosed patients were treated [HyperCVAD-based (n = 531); Augmented BFM (n = 116)]. Six hundred and one (93%) achieved complete remission (CR), and 546 (91%) became MRD negative. Fifty-five patients [HyperCVAD-based (n = 49); Augmented BFM (n = 6)] developed recurrence of MRD while still in morphological CR and are the subjects of this study...

The myelodysplastic syndromes (MDS) comprise a heterogenous group of myeloid disorders with a highly variable disease course. Diagnostic criteria to better stratify patients with MDS continue to evolve, based on morphology, cytogenetics, and the presence of cytopenias. More accurate classification of patients will allow for better treatment guidance. Treatment encompasses supportive care, treatment of anemia, low-intensity therapy, and high-intensity therapy. This portion of the guidelines focuses on diagnostic classification, molecular abnormalities, therapeutic options, and recommended treatment approaches...
