    [EN] Objective To describe the development, as part of the European Union MOSAIC (Models and Simulation Techniques for Discovering Diabetes Influence Factors) project, of a dashboard-based system for the management of type 2 diabetes and assess its impact on clinical practice. Methods The MOSAIC dashboard system is based on predictive modeling, longitudinal data analytics, and the reuse and integration of data from hospitals and public health repositories. Data are merged into an i2b2 data warehouse, which feeds a set of advanced temporal analytic models, including temporal abstractions, care-flow mining, drug exposure pattern detection, and risk-prediction models for type 2 diabetes complications. The dashboard has 2 components, designed for (1) clinical decision support during follow-up consultations and (2) outcome assessment on populations of interest. To assess the impact of the clinical decision support component, a pre-post study was conducted considering visit duration, number of screening examinations, and lifestyle interventions. A pilot sample of 700 Italian patients was investigated. Judgments on the outcome assessment component were obtained via focus groups with clinicians and health care managers. Results The use of the decision support component in clinical activities produced a reduction in visit duration (P¿¿¿.01) and an increase in the number of screening exams for complications (PÂż<Âż.01). We also observed a relevant, although nonstatistically significant, increase in the proportion of patients receiving lifestyle interventions (from 69% to 77%). Regarding the outcome assessment component, focus groups highlighted the systemÂżs capability of identifying and understanding the characteristics of patient subgroups treated at the center. Conclusion Our study demonstrates that decision support tools based on the integration of multiple-source data and visual and predictive analytics do improve the management of a chronic disease such as type 2 diabetes by enacting a successful implementation of the learning health care system cycle.This work was supported by the European Union in the Seventh Framework Programme, grant number 600914.Dagliati, A.; Sacchi, L.; Tibollo, V.; Cogni, G.; Teliti, M.; Martinez-Millana, A.; Traver Salcedo, V....

    Interactions between herbivorous insects and plants storing terpenoids are poorly understood. This study describes the ability of Chrysolina herbacea to use volatiles emitted by undamaged Mentha aquatica plants as attractants and the plant's response to herbivory, which involves the production of deterrent molecules. Emitted plant volatiles were analyzed by GC-MS. The insect's response to plant volatiles was tested by Y-tube olfactometer bioassays. Total RNA was extracted from control plants, mechanically damaged leaves, and leaves damaged by herbivores. The terpenoid quantitative gene expressions (qPCR) were then assayed. Upon herbivory, M. aquatica synthesizes and emits (+)-menthofuran, which acts as a deterrent to C. herbacea. Herbivory was found to up-regulate the expression of genes involved in terpenoid biosynthesis. The increased emission of (+)-menthofuran was correlated with the upregulation of (+)-menthofuran synthase

    Isolation of a natural DNA virus of <i>Drosophila melanogaster</i>, and characterisation of host resistance and immune responses

    <div><p><i>Drosophila melanogaster</i> has played a key role in our understanding of invertebrate immunity. However, both functional and evolutionary studies of host-virus interaction in <i>Drosophila</i> have been limited by a dearth of native virus isolates. In particular, despite a long history of virus research, DNA viruses of <i>D</i>. <i>melanogaster</i> have only recently been described, and none have been available for experimental study. Here we report the isolation and comprehensive characterisation of Kallithea virus, a large double-stranded DNA virus, and the first DNA virus to have been reported from wild populations of <i>D</i>. <i>melanogaster</i>. We find that Kallithea virus infection is costly for adult flies, reaching high titres in both sexes and disproportionately reducing survival in males, and movement and late fecundity in females. Using the <i>Drosophila</i> Genetic Reference Panel, we quantify host genetic variance for virus-induced mortality and viral titre and identify candidate host genes that may underlie this variation, including <i>Cdc42-interacting protein 4</i>. Using full transcriptome sequencing of infected males and females, we examine the transcriptional response of flies to Kallithea virus infection and describe differential regulation of virus-responsive genes. This work establishes Kallithea virus as a new tractable model to study the natural interaction between <i>D</i>. <i>melanogaster</i> and DNA viruses, and we hope it will serve as a basis for future studies of immune responses to DNA viruses in insects.</p></div

    The main post uretero-sigmoidostomy complications are stricture of the anastomosis, chronic infection and urolithiasis. In our institution the patients with ureterosigmodostomy undergo a follow-up protocol in which blood chemistry, ultrasonography, intravenous pyelography and C.T. are periodically performed. The aim of the present paper is to compare the accuracy of kidney sonography after diuretic stimulation with intravenous pyelography in the diagnosis of ureteral stenosis. Out of 91 patient with ureterosigmoidostomy 18 patients (34 kidneys) underwent intravenous pyelography, a basal U.S. and then a dynamic one at 5, 10, 15, 30, 45, 60, 90, 120 minutes after administration of furosemide 20 mg i.v. At basal U.S. 27 kidneys were normal and 7 showed a dilations. After diuretic stimulation we observed 16 normal kidneys, 16 dilated units and 2 intermittent hydronephrosis. Out of 16 dilated kidneys 6 became normal in 60 minutes. Out of 10 dilated units 3 were normal in 90 minutes (hipotonic), 2 were normal before 120 minutes (low grade obstruction) and 5 were dilated after 120 minutes (high grade obstruction). With intravenous pyelography we observed 27 normal kidneys and seven dilated units. Dynamic sonography have shown high sensibility (100%), specificity (88.8%) and accuracy (91%) in diagnosis of ureteral obstruction in to I.V.P. in the follow-up of this kind of divesion

    Accuracy of suprapubic (SP), transrectal (TR), and transvaginal (TV) ultrasonography (US) in diagnosis and preoperative staging of bladder carcinoma is evaluated. From January 1990 to December 1992, 354 patients with gross haematuria, underwent bladder SP-US and cystoscopy and of this group 216 patients had transitional bladder cancer. Diagnostic sensitivity, specificity and accuracy for SP-US were, respectively, 73.5%, 88.5% and 63.8%. Clinical US and pathological staging were compared in 116 patients: downstaging was observed in 43.1% of the cases by SP-US and in 34.5% of the cases by TR-US or TV-US and overstaging in 6.9% of the cases by SP-US and in 15.4% of the cases by TR-US or TV-US. In this series accuracy of clinical staging by SP-US, TR-US, TV-US was inversely related to cancer stage and, conversely, clinical staging by pelvic CT scan accuracy is directly related to cancer stage

    Temporal distribution in a tri-trophic system associated with piper amalago L. in a tropical seasonal forest

    No full text
    Insect seasonality is a known pattern that has intrigued ecologists for over 30 years. However, despite being well understood in general, for several taxa such as Lepidopteran caterpillars its underlying causes and mechanisms are still not fully understood. This is especially critical for Brazilian tropical forests where caterpillars have previously been shown to have a puzzling pattern of peaking in abundance only in the first months of the dry season; however, this pattern still lacks an explanation. Here, to advance our understanding of the factors underlying seasonal changes in caterpillar abundance in tropical forests, we addressed how the lepidopteran caterpillar community that feeds on Piper amalago L. plants, their host plants leaf numbers, the herbivory levels, and the parasitoid pressure all change throughout the dry and wet seasons in a Brazilian tropical semideciduous forest. We found that immature abundance and herbivory peak in the first 2 months of the dry season and then rapidly decrease and remain low throughout the remaining of the dry season and the entire wet season at the study site. However, although the proportion of parasitized immatures increased alongside caterpillar abundance, it peaked in the month that followed a drastic decrease in caterpillar abundance. These results suggest that parasitoids play a major role in the observed caterpillar abundance pattern and thus, we propose the hypothesis that high parasitoid predation pressure causes early eclosion and emergence of caterpillars and primarily drives caterpillar abundance seasonality in Brazilian tropical forests134647652CNPQ - Conselho Nacional de Desenvolvimento Científico e TecnológicoFAPESP – Fundação de Amparo à Pesquisa Do Estado De São Paulo303834/2015-3; 307015/2015-7; 563332/2010-72014/50316-7; 2016/01380-0; 2011/50225-3; 2013/25991-0We thank Massuo J.

    The present treatment of the subacute abatteric prostatitis, prostatodinia, prostatosis (the most common prostatic flogistic diseases) is represented by the transrectal applications of infrared Laser. The concrete opportunity of applying such an energy directly to the prostate in cases of flogistic diseases--a very frequent pathology treated in many different and controversial ways--is a stimulating therapeutical method which we tested and that we presently use in our clinics. The thanks to the realization of an high technology equipment, easy to handle, cheap, safe, perfectly suitable, formed by a new infrared Laser probe, transrectal, atermical, made by a optical fibre, which we present. Micturition, ejaculation, fertility may draw a relevant improvement, provided that the same treatment is performed after a specific medical diagnosis and following a strict protocol

    Validity of superficial echography in the study of urethral pathology

    No full text
    In male patients routine examination for urethral disease includes retrograde and anterograde urethrography and urethroscopy. In the patients underwent radical cystectomy, detection of cancerous cells in the urethral washing suggest cancer relapse. Nowadays we can achieve a sonographic study of the anterior male urethra, using a superficial high frequency ultrasound probe. Since September 1992 till July 1993, 12 patients underwent cystectomy at our Institution and 13 patients affected by urethral stricture, have been investigated by routine examination and sonographic urethrogram. In the first group of patients, out of 3 patients with urethral tumor, sonourethrography has confirmed the presence of tumor in 2 cases. In these second group of patients, sonourethrography has located the stricture, evaluated the length, calculated the diameter of the stricture and the depth of fibrosis. Sonourethrography is a non-invasive method that can provide valuable information about the urethral lumen and the urethral wall
