Azacitidine for myelodysplastic patients aged > 65 years: a review of clinical efficacy.
No full textINTRODUCTION: Therapeutic strategies for elderly patients affected by myelodysplastic syndromes (MDS) are scarce and only few patients have an advantage in performing allogeneic bone marrow transplant.
AREAS COVERED: Primary endpoints for treatment of elderly MDS patients were not curative, but rather allowing to maintain a good quality of life through prolongation of overall survival. In this context, azacitidine showed to improve responses in this subset of patients compared to conventional established regimens, such as intensive or low-dose chemotherapy and best supportive care. Good safety profile of the drug was reported either when it was used inside or outside clinical trials. Improved quality of response was observed when the drug was administered beyond the first response, and it is now usually recommended to continue it at the same dose and schedule in responding patients.
EXPERT OPINION: Evaluation of baseline prognostic factors and comorbidities may help to identify patients who can benefit from the prolonged administration of the drug. Real life data regarding efficacy and safety of azacitidine in MDS elderly patients are required in order to confirm the results of clinical trials

Application of systematic coronary risk evaluation chart to identify chronic myeloid leukemia patients at risk of cardiovascular diseases during nilotinib treatment.
No full textNilotinib is currently approved for the treatment of chronic myeloid leukemia (CML) in chronic (CP) and accelerated phase (AP) after failure of imatinib and in newly diagnosed patients. Atherosclerotic events were retrospectively reported in patients with baseline cardiovascular risk factors during nilotinib treatment. We estimated the risk of developing atherosclerotic events in patients treated with second or first-line nilotinib, with a median follow-up of 48 months, by retrospectively applying the SCORE chart proposed by the European Society of Cardiology (ESC) and evaluating risk factors at baseline (diabetes, obesity, smoking, and hypertension). Overall, we enrolled in the study 82 CP patients treated frontline (42 CP patients at the dose of 600 mg BID) or after failure of other tyrosine kinase inhibitors (40 CP patients treated with 400 mg BID). The SCORE chart is based on the stratification of sex (male vs female), age (from 40 to 65 years), smoker vs non-smoker, systolic pressure (from 120 to 180 mm Hg), and cholesterol (measured in mmol/l, from 150 to 300 mg/dl). For statistical purposes, we considered patients subdivided in low, moderate, high (with a score >5), and very high risk. There were 48 males and 34 females, median age 51 years (range 22-84). According to WHO classification, 42 patients were classified as normal weight (BMI 30). Retrospective classification according to the SCORE chart revealed that 27 patients (33 %) were in the low-risk category, 30 patients (36 %) in the moderate risk category, and 24 patients (29 %) in the high risk. As regards risk factors, we revealed that 17 patients (20.7 %) had a concomitant type II controlled diabetes (without organ damage), 23 patients (28 %) were smokers, 29 patients (35 %) were receiving concomitant drugs for hypertension, and 15 patients (18 %) had concomitant dyslipidemia. Overall, the cumulative incidence of atherosclerotic events at 48 months was 8.5 % (95 % CI, 4.55-14.07): None of the low-risk patients according to the SCORE chart experienced atherosclerotic events compared to 10 % in the moderate risk category and 29 % in the high risk (p = 0.002). Atherosclerotic-free survival was 100, 89, and 69 % in the low, moderate, and high-risk population, respectively (p = 0.001). SCORE chart evaluation at disease baseline could be a valid tool to identify patients at high risk of atherosclerotic events during nilotinib treatment

Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
