PV reduces survival expectation, primarily due to thrombotic events, transformation to blast phase and post-PV myelofibrosis or to development of second cancers, which are associates with poor prognosis. Current therapeutic first line recommendations based on risk adapted classification divided patients into two groups, according to age (< or > 60 years) and presence of prior thrombotic events. Low-risk patients (age < 60 years and no prior history of thrombosis) should be treated with aspirin (81– 100 mg/d) and phlebotomy, to maintain hematocrit < 45%. High-risk patients (age > 60 years and/or prior history of thrombosis), in addition to aspirin and phlebotomies, should receive cytoreductive therapy in order to reduce thrombotic risk. Nowadays hydroxyurea still remains the cytoreductive agent of first choice, reserving Interferon to young patients or childbearing women. During the last years, ruxolitinib emerged as a new treatment in PV patients, as second line therapy: it appeared especially effective in patients with severe pruritus, symptomatic splenomegaly, or post-PV myelofibrosis symptoms. Currently, in PV treatment, several molecules have been tested or are under investigation. At present, the drug that has shown the most encouraging results is givinostat.Keywords: polycythemia vera, therapy, ruxolitinib, interferon, givinostat

An accurate estimation of AML prognosis is complex since it depends on patient-related factors, AML manifestations at diagnosis, and disease genetics. Furthermore, the depth of response, evaluated using the level of MRD, has been established as a strong prognostic factor in several AML subgroups. In recent years, this rapidly evolving field has made the prognostic evaluation of AML more challenging. Traditional prognostic factors, established in cohorts of patients treated with standard intensive chemotherapy, are becoming less accurate as new effective therapies are emerging. The widespread availability of next-generation sequencing platforms has improved our knowledge of AML biology and, consequently, the recent ELN 2022 recommendations significantly expanded the role of new gene mutations. However, the impact of rare co-mutational patterns remains to be fully disclosed, and large international consortia such as the HARMONY project will hopefully be instrumental to this aim. Moreover, accumulating evidence suggests that clonal architecture plays a significant prognostic role. The integration of clinical, cytogenetic, and molecular factors is essential, but hierarchical methods are reaching their limit. Thus, innovative approaches are being extensively explored, including those based on "knowledge banks". Indeed, more robust prognostic estimations can be obtained by matching each patient's genomic and clinical data with the ones derived from very large cohorts, but further improvements are needed.

In the present study, we aimed to evaluate the absolute risk of infection in the real-life setting of AML patients treated with CPX-351. The study included all patients with AML from 30 Italian hematology centers of the SEIFEM group who received CPX-351 from July 2018 to June 2021. There were 200 patients included. Overall, 336 CPX-351 courses were counted: all 200 patients received the first induction cycle, 18 patients (5%) received a second CPX-351 induction, while 86 patients (26%) proceeded with the first CPX-351 consolidation cycle, and 32 patients (10%) received a second CPX-351 consolidation. A total of 249 febrile events were recorded: 193 during the first or second induction, and 56 after the first or second consolidation. After the diagnostic work-up, 92 events (37%) were classified as febrile neutropenia of unknown origin (FUO), 118 (47%) were classifiable as microbiologically documented infections, and 39 (17%) were classifiable as clinically documented infections. The overall 30-day mortality rate was 14% (28/200). The attributable mortality-infection rate was 6% (15/249). A lack of response to the CPX-351 treatment was the only factor significantly associated with mortality in the multivariate analysis [ p -value: 0.004, OR 0.05, 95% CI 0.01-0.39]. Our study confirms the good safety profile of CPX-351 in a real-life setting, with an incidence of infectious complications comparable to that of the pivotal studies; despite prolonged neutropenia, the incidence of fungal infections was low, as was infection-related mortality.

Objectives: Chemotherapy-induced neutropenia in acute myeloid leukaemia (AML) is a risk factor for life-threatening infections. Early diagnosis and prompt interventions are associated with better outcomes, but the prediction of infection severity remains an open question. Recently, National Early Warning Score (NEWS) and quick sequential organ failure assessment (qSOFA) scores were proposed as warning clinical instruments predicting in-hospital mortality, but their role in the haematological context is still unknown., Methods: We retrospectively assess the predictive role of NEWS and qSOFA in a large and homogeneous cohort of adult AML patients treated with intensive chemotherapy. In a total of 1048 neutropenic episodes recorded in 334 consecutive patients, the scores were applied to predict outcomes on the same day of fever onset, and after 24 and 48 h from score calculation., Results: Both NEWS and qSOFA significantly predicted death, with more accuracy on the same day (NEWS AUROC 0.984 and qSOFA AUROC 0.969) and after 24 h (NEWS AUROC 0.928 and qSOFA AUROC 0.887), while remained moderately accurate after 48 h. Furthermore, also ICU admission was accurately predicted at fever onset and after 24 h., Conclusions: Both scores were useful tools in the management of post chemotherapy neutropenic febrile AML patients., (© 2023 John Wiley & Sons A/S.

Background: Acute myeloid leukemia (AML) patients are at high risk of infections during post-induction neutropenia. Recently, the role of antibacterial prophylaxis has been reconsidered due to concerns about the emergence of multi-resistant pathogens. The aim of the present study was to evaluate the impact of avoiding prophylaxis on the rate of induction death (primary endpoint), neutropenic fevers, bloodstream infections (BSIs), resistant pathogens BSIs and septic shocks (secondary endpoints)., Methods: We performed a retrospective single-center study including 373 AML patients treated with intensive induction chemotherapy, divided into two groups according to levofloxacin prophylaxis given (group A, gA) or not (group B, gB)., Results: Neutropenic fever was observed in 91% of patients in gA and 97% in gB (OR 0.35, IC95% 0.08 - 1.52, p=0162). The rate of BSIs was 27% in gA compared to 34% in gB (OR 0.69, 0.38 - 1.25, p=0.222). The induction death rate was 5% in gA and 3% in gB (OR 1.50, 0.34 - 6.70, p=0.284). Fluoroquinolones (FQ) resistant pathogens were responsible for 59% of total BSIs in gA and 22% in gB (OR 5.07, 1.87 - 13.73, p=0.001); gram-negative BSIs due to multi-drug resistant organisms were 31% in gA and 36% in gB (OR 0.75, 0.15 - 3.70, p=0.727)., Conclusions: Despite its limitations (retrospective nature, single-center, different cohort size), the present study showed that avoiding levofloxacin prophylaxis was not associated with an increased risk of induction death. The cumulative incidence of neutropenic fever was higher in non-prophylaxis group, while no difference was observed for BSIs. In the prophylaxis group we observed a higher incidence of FQ-resistant organisms., Competing Interests: Competing interests: The authors declare no conflict of Interest.

The frequency of thrombosis in AML has been evaluated only in a few studies and no validated predictive model is currently available. Recently, DIC score was shown to identify patients at higher thrombotic risk. We aimed to evaluate the frequency of thromboembolism in AML patients treated with intensive chemotherapy and to assess the ability of genetic and clinical factors to predict the thrombotic risk. We performed a retrospective observational study including 222 newly diagnosed adult AML (210) and high-risk MDS (12), treated with intensive chemotherapy between January 2013 and February 2020. With a median follow-up of 44 months, we observed 50 thrombotic events (90% were venous, VTE). The prevalence of thrombosis was 22.1% and the 6-months cumulative incidence of thrombosis was 10%. The median time to thrombosis was 84 days and 52% of the events occurred within 100 days from AML diagnosis. Khorana and DIC score failed to stratify patients according to their thrombotic risk. Only history of a thrombotic event (p = 0.043), particularly VTE (p = 0.0053), platelet count above 100 × 10 9 /L at diagnosis (p = 0.036) and active smoking (p = 0.025) significantly and independently increased the risk of thrombosis, the latter particularly of arterial events. AML genetic profile did not affect thrombosis occurrence. Results were confirmed considering only thromboses occurring within day 100 from diagnosis. DIC score at diagnosis, but not thrombosis, was independently associated with reduced survival (p = 0.004). Previous VTE, platelet count above 100 × 10 9 /L and active smoking were the only factors associate with increased thrombotic risk in AML patients treated intensively, but further studies are needed to validate these results., (© 2022.

Acute myeloid leukemia (AML) in older patients is characterized by unfavorable prognosis due to adverse disease features and a high rate of treatment-related complications. Classical therapeutic options range from intensive chemotherapy in fit patients, potentially followed by allogeneic hematopoietic cell transplantation (allo-HCT), to hypomethylating agents or palliative care alone for unfit/frail ones. In the era of precision medicine, the treatment paradigm of AML is rapidly changing. On the one hand, a plethora of new targeted drugs with good tolerability profiles are becoming available, offering the possibility to achieve a prolonged remission to many patients not otherwise eligible for more intensive therapies. On the other hand, better tools to assess patients' fitness and improvements in the selection and management of those undergoing allo-HCT will hopefully reduce treatment-related mortality and complications. Importantly, a detailed genetic characterization of AML has become of paramount importance to choose the best therapeutic option in both intensively treated and unfit patients. Finally, improving supportive care and quality of life is of major importance in this age group, especially for the minority of patients that are still candidates for palliative care because of very poor clinical conditions or unwillingness to receive active treatments. In the present review, we discuss the evolving approaches in the treatment of older AML patients, which is becoming increasingly challenging following the advent of new effective drugs for a very heterogeneous and complex population.

During the Modern Age, in the Marche, in the Pontifical State, it was possible to study medicine and to obtain a degree in medicine in Macerata, Fermo, Urbino, Camerino and Fano. In these cities, from the end of the XVII century to the beginning of the XIX century, public libraries were founded also to support academic teaching. Private collections of medical books, generally formed in Rome, arrived in the Marche to increase the newborn public libraries. In 1720 Pope Clemens XI founded a public library in the monastery of Saint Francis in Urbino. In this library the medical books were bequeathed by the famous Roman physician Giovanni Maria Lancisi. The present article provides the first results of a research, which aims at identifying Lancisi's medical books.
