Uncovering the expression of circPVT1 in the extracellular vesicles of acute myeloid leukemia patients.

Extracellular vesicles (EVs) act as molecular mediators in the tumor microenvironment, by shuttling information contained within malignant cells and functioning as regulators of the immune system. Circular (circ)RNAs are characterized by a closed loop-like structure that makes them more stable in the extracellular milieu and suitable to be packaged inside EVs. circPVT1 (hsa_circ_0001821) showed an oncogenic role in several cancer types and immunosuppressive properties in myeloid and lymphoid cell subsets.

Ten Years of Medical Informatics and Standards Support for Clinical Research in an Infectious Diseases Network.

Background: It is 30 years since evidence-based medicine became a great support for individual clinical expertise in daily practice and scientific research. Electronic systems can be used to achieve the goal of collecting data from heterogeneous datasets and to support multicenter clinical trials. The (LIDN) is a web-based platform for data collection and reuse originating from a regional effort and involving many professionals from different fields.

The Ligurian HIV Network: How Medical Informatics Standards Can Help Clinical Research.

Integrating evidence from systematic research in daily clinical practice is one of the pillars of evidence-based medicine. Electronic data capture tools simplify data collection from different centers and supports the management of multicenter clinical trials. The Ligurian HIV Network (LHN) is one such tool, originating from a regional effort to integrate clinical trial capabilities for HIV and other chronic infectious diseases.

How has the cost of antiretroviral therapy changed over the years? A database analysis in Italy.

Background: The number of human immunodeficiency virus (HIV)-related hospitalizations has decreased worldwide in recent years, due to the availability of combined antiretroviral therapies (cART). The present analysis aimed to analyse the economic, and clinical burden of HIV management, after the introduction of systematic use of cART.

Methods: Data from HIV-infected patients, treated at Policlinico San Martino Hospital in Genova (Italy) were retrospectively collected.

HAART Prescription Support Tool for Personalized Therapy.

The importance of decision support systems is highly acknowledged as a key strategy to improve medical safety and quality of care. A strong interoperability between the hospital Electronic Health Record (EHR) and the Clinical Decision Support System (CDSS) is the key to reach a most reliable decision support, that could aid in better diagnosis, reduce medication errors and improve practitioner performances. Interoperability is granted by the use of standards for data representation and for system intercommunication.

Electronic Health Records: From the Management of Patients to the Research Use of Clinical Data.

Paper based medical records are still widespread in Italian hospitals and the workflow to manage outpatients' visits is critical. Too many isolated software programs coexist in hospital wards and cause confusion and disorganization. A computerized medical record that unifies all the data contained in the various applications should be of fundamental importance in supporting physician's daily activities.

Predictors of retention in care in HIV-infected patients in a large hospital cohort in Italy.

Retention in care is a key feature of the cascade of continuum of care, playing an important role in achieving therapeutic success and being crucial for reduction of HIV transmission. The aim of this study was to evaluate the rate of retention in care in a large referral centre in the North of Italy and to identify predictors associated with failed retention. All new HIV-infected subjects were consecutive enrolled from 1 January 2008 to 31 December 2014.

A Web Based Tool to Enhance Monitoring and Retention in Care for Tuberculosis Affected Patients.

Tuberculosis (TB) is responsible for a global epidemic. TB treatment requires long-term therapy usually with multiple drugs, which have potential side effects and interactions that may influence patients' adherence to treatment. The TB Ge network is a multi-centric web based platform that collects clinical information of TB affected patients to increase their support and retention in care.

Assessment of the interlaboratory variability and robustness of JAK2V617F mutation assays: A study involving a consortium of 19 Italian laboratories.

To date, a plenty of techniques for the detection of JAK2V617F is used over different laboratories, with substantial differences in specificity and sensitivity. Therefore, to provide reliable and comparable results, the standardization of molecular techniques is mandatory.A network of 19 centers was established to 1) evaluate the inter- and intra-laboratory variability in JAK2V617F quantification, 2) identify the most robust assay for the standardization of the molecular test and 3) allow consistent interpretation of individual patient analysis results.

Is it still worthwhile to perform quarterly cd4+ t lymphocyte cell counts on hiv-1 infected stable patients?

Background: In the last 20 years routine T CD4+ lymphocyte (CD4+) cell count has proved to be a key factor to determine the stage of HIV infection and start or discontinue of prophylaxis for opportunistic infections. However, several studies recently showed that in stable patients on cART a quarterly CD4+ cell count monitoring results in limited (or null) clinical relevance. The research is intended to investigate whether performing quarterly CD4+ cell counts in stable HIV-1 patients is still recommendable and to provide a forecast of the cost saving that could be achieved by reducing CD4+ monitoring in such a category of patients.

A SOA-Based Solution to Monitor Vaccination Coverage Among HIV-Infected Patients in Liguria.

Vaccination in HIV-infected patients constitutes an essential tool in the prevention of the most common infectious diseases. The Ligurian Vaccination in HIV Program is a proposed vaccination schedule specifically dedicated to this risk group. Selective strategies are proposed within this program, employing ICT (Information and Communication) tools to identify this susceptible target group, to monitor immunization coverage over time and to manage failures and defaulting.

Budget impact analysis of sofosbuvir-based regimens for the treatment of HIV/HCV-coinfected patients in northern Italy: a multicenter regional simulation.

Objectives: Chronic hepatitis C virus (HCV) is a leading cause of hospitalization and death in populations coinfected with human immunodeficiency virus (HIV). Sofosbuvir (SOF) is a pan-genotypic drug that should be combined with other agents as an oral treatment for HCV. We performed a 5-year horizon budget impact analysis of SOF-based regimens for the management of HIV/HCV-coinfected patients.

IANUA: a regional project for the determination of costs in HIV-infected patients.

HIV treatment is based on combined antiretroviral therapy (cART) which has substantially improved survival, thus resulting in an increase in patient life expectancy as well as in the cost of HIV-related medical care. Therefore, several cost effectiveness studies were implemented worldwide, with one specifically in the Liguria region (Italy), to compare the annual economic expense in this area for HIV services, and the related improvement in patients' health. The IANUA project is intended to implement both cost-effectiveness and cost-utility analysis, therefore data related to clinical indicators and perceived health status were collected, the latter using a questionnaire based on the EQ-5D-3L.

Quality of life of people living with HIV, preliminary results from IANUA (Investigation on Antiretroviral Therapy) study.

Introduction: The introduction of combined antiretroviral treatment (cART) has reduced HIV-associated morbidity and mortality, and changed the patients' perspective of life. As a result, Health Related Quality of Life (HRQOL) has become a crucial clinical issue.

Objective: Assessment of HRQOL in a sample of Italian patients from IANUA study.

Unraveling the complexity of tyrosine kinase inhibitor-resistant populations by ultra-deep sequencing of the BCR-ABL kinase domain.

In chronic myeloid leukemia and Philadelphia chromosome-positive acute lymphoblastic leukemia, tyrosine kinase inhibitor (TKI) therapy may select for drug-resistant BCR-ABL mutants. We used an ultra-deep sequencing (UDS) approach to resolve qualitatively and quantitatively the complexity of mutated populations surviving TKIs and to investigate their clonal structure and evolution over time in relation to therapeutic intervention. To this purpose, we performed a longitudinal analysis of 106 samples from 33 patients who had received sequential treatment with multiple TKIs and had experienced sequential relapses accompanied by selection of 1 or more TKI-resistant mutations.

Chromosome abnormalities additional to the Philadelphia chromosome at the diagnosis of chronic myelogenous leukemia: pathogenetic and prognostic implications.

Additional chromosome abnormalities (ACAs) occur in less than 10% of cases at diagnosis of Philadelphia chromosome (Ph)-positive chronic myelogenous leukemia (CML). In some cases, on the basis of the persistence of the ACAs in Ph-negative cells after response to imatinib, a secondary origin of the Ph chromosome has been demonstrated. In this study, the possible prognostic value of this phenomenon was evaluated.

ABL mutations in late chronic phase chronic myeloid leukemia patients with up-front cytogenetic resistance to imatinib are associated with a greater likelihood of progression to blast crisis and shorter survival: a study by the GIMEMA Working Party on Chronic Myeloid Leukemia.

Purpose: Point mutations within the ABL kinase domain of the BCR-ABL gene have been associated with clinical resistance to imatinib mesylate in chronic myeloid leukemia (CML) patients. To shed further light on the frequency, distribution, and prognostic significance of ABL mutations, we retrospectively analyzed a homogeneous cohort of late chronic phase CML patients who showed primary cytogenetic resistance to imatinib.

Patients And Methods: Using denaturing high-performance liquid chromatography (D-HPLC) and sequencing, we screened for ABL mutations in a total of 178 bone marrow and/or peripheral blood samples from 40 late chronic phase CML patients homogeneously treated with imatinib 400 mg/d, who did not reach a major cytogenetic response at 12 months.

Molecular response to imatinib in late chronic-phase chronic myeloid leukemia.

Imatinib is a tyrosine-kinase inhibitor that binds to ABL proteins and induces cytogenetic remissions in patients with chronic myeloid leukemia (CML). In these patients measuring response by molecular techniques is clearly required. We determined the cytogenetic and molecular response (CgR, MR) to imatinib in 191 patients with late chronic-phase Philadelphia-positive (Ph+) CML, previously treated with interferon alpha.

Rapid detection of Flt3 mutations in acute myeloid leukemia patients by denaturing HPLC.

Background: fms-related tyrosine kinase 3 (Flt3) is the most commonly mutated gene in human acute myeloid leukemia (AML) and has been implicated in its pathogenesis. Because screening of Flt3 in AML patients by PCR followed by gel electrophoresis is time-consuming and fails to detect some very small internal tandem duplications (ITDs), we developed a method for screening of FLT3 receptor mutations with PCR plus denaturing HPLC (D-HPLC).

Methods: Total mRNAs extracted from 34 AML patients were first analyzed for the presence of juxtamembrane length mutations and tyrosine kinase domain point mutations by a conventional method involving PCR amplification, restriction enzyme digestion, and agarose gel electrophoresis (PCR-RED-AGE).

Cyclin D1 overexpression is a favorable prognostic variable for newly diagnosed multiple myeloma patients treated with high-dose chemotherapy and single or double autologous transplantation.

We used a sensitive real-time reverse transcription-polymerase chain reaction assay to quantify cyclin D1 mRNA levels in bone marrow samples collected at diagnosis from 74 newly diagnosed multiple myeloma (MM) patients who were randomized to undergo either single or double autologous peripheral blood stem cell transplantation as part of first-line therapy for their malignancy. In 46 cases, fluorescence in situ hybridization (FISH) analysis and/or conventional cytogenetics were performed to detect chromosome 11 abnormalities. Patients with the t(11;14) or trisomy 11 significantly overexpressed cyclin D1 (P <.
