    <p>Abstract</p> <p>Background</p> <p>Injury severity measures are based either on the Abbreviated Injury Scale (AIS) or the International Classification of diseases (ICD). The latter is more convenient because routinely collected by clinicians for administrative reasons. To exploit this advantage, a proprietary program that maps ICD-9-CM into AIS codes has been used for many years. Recently, a program called ICDPIC trauma and developed in the USA has become available free of charge for registered STATA<sup>® </sup>users. We compared the ICDPIC calculated Injury Severity Score (ISS) with the one from direct, prospective AIS coding by expert trauma registrars (dAIS).</p> <p>Methods</p> <p>The administrative records of the 289 major trauma cases admitted to the hospital of Udine-Italy from 1 July 2004 to 30 June 2005 and enrolled in the Italian Trauma Registry were retrieved and ICDPIC-ISS was calculated. The agreement between ICDPIC-ISS and dAIS-ISS was assessed by Cohen's Kappa and Bland-Altman charts. We then plotted the differences between the 2 scores against the ratio between the number of traumatic ICD-9-CM codes and the number of dAIS codes for each patient (DIARATIO). We also compared the absolute differences in ISS among 3 groups identified by DIARATIO. The discriminative power for survival of both scores was finally calculated by ROC curves.</p> <p>Results</p> <p>The scores matched in 33/272 patients (12.1%, k 0.07) and, when categorized, in 80/272 (22.4%, k 0.09). The Bland-Altman average difference was 6.36 (limits: minus 22.0 to plus 34.7). ICDPIC-ISS of 75 was particularly unreliable. The differences increased (p < 0.01) as DIARATIO increased indicating incomplete administrative coding as a cause of the differences. The area under the curve of ICDPIC-ISS was lower (0.63 vs. 0.76, p = 0.02).</p> <p>Conclusions</p> <p>Despite its great potential convenience, ICPIC-ISS agreed poorly with its conventionally calculated counterpart. Its discriminative power for survival was also significantly lower. Incomplete ICD-9-CM coding was a main cause of these findings. Because this quality of coding is standard in Italy and probably in other European countries, its effects on the performances of other trauma scores based on ICD administrative data deserve further research. Mapping ICD-9-CM code 862.8 to AIS of 6 is an overestimation.</p

    Introduction: The disease activity associated with the drug-utilization patterns of biologic Disease Modifying Anti-Rheumatic Drugs (DMARDs) is poorly investigated in real-world studies on rheumatoid arthritis (RA) patients. To investigate the relationship between biologic DMARD initiation/discontinuations in RA patients identified in the healthcare administrative databases of Tuscany and the Disease Activity Score 28 (DAS28) reported in the medical charts.Methods: This retrospective population-based study included RA’s first-ever biologic DMARD users of the Pisa University Hospital from 2014 to 2016. Patients were followed up until 31 December 2019. We evaluated the DAS28 recorded before (T0) and after (T1) the biologic DMARD initiation and before (TD0) and after (TD1) discontinuations. Patients were classified as “off-target” (DAS28 &gt; 3.2) or “in-target” (DAS28 ≤ 3.2). We described the disease activity trends at initiation and discontinuation.Results: Ninety-five users were included (73 women, mean age 59.6). Among 70 patients (74%) with at least three DAS28 measures, 28 (40.0%) were off-target at T0 and 38 (54.3%) in-target at T1. Thirty-three (47%) patients had at least one discontinuation, among those with at least three DAS28 assessments. In the disease activity trend, disease stability or improvement was observed in 28 out of 37 (75.7%) patients at initiation and in 24 out of 37 (64.9%) at discontinuation.Discussion: Biologic DMARD discontinuations identified in the healthcare administrative databasese of Tuscany are frequently observed in situations of controlled RA disease. Further studies are warranted to confirm that these events can be used in studies using healthcare administrative databases as proxies of treatment effectiveness

    Consommation alimentaire - alcoolique et perception du risque: exemple d'une problématique de "santé" dans les terres italiennes caractérisées par la production du vin (Udine, Nord d'Italie)

    Cette étude a pour objet la relation entre les modes de consommations (alimentation - alcool - tabac) d'une part, et la perception du risque de santé, d'autre part. Nous nous sommes interrogés sur la relation entre les définitions de "santé" et de "bien-être" (éléments culturels), les modes de consommation, et les problèmes de santé liés à cette consommation (éléments biologiques). Cette thématique occupe aujourd'hui une place importante dans le débat interdisciplinaire qui intéresse anthropologues, écologues et aussi médecins: les déterminants socioculturels de la santé sont de plus en plus indiqués par les spécialistes parmi les premières causes de mal-être et de maladie dans les sociétés occidentales contemporaines. Notre enquête a été réalisée au cours de l'année 2004 dans 34 communes de la Province de Udine (Nord d'Italie): 800 personnes environ ont été interviewées à propos de leur représentation du risque de santé, de leur consommation alcoolique, de leurs réseaux familiaux et amicaux, ainsi que de leurs problèmes de santé avérés. L'intérêt de notre étude se base aussi sur le fait que l'aire géographique concernée par la recherche est depuis longtemps une aire de production de vin: d'un côté, la production agricole est une ressource et le vin représente une partie importante des connaissances et de la culture locale; d'un autre côté, le taux élevé d'alcooliques témoigne des tensions de la société contemporaine qui ont perturbé l'équilibre entre l'homme et ses ressources. La recherche se propose aussi comme outil pour l'établissement de politiques de prévention qui prennent en compte les éléments culturels caractérisant les modes de consommations dans chaque communauté, comme la définition de santé, la perception du risque, la signification des consommations en termes de sociabilisation.The main aim of this study is to understand the relationship between alcohol consumption and risk perception of these health determinants among general population in Italian wine producers regions (Udine, Northern Italy). 800 people were asked about these and other items (different ways of alcohol consumption; risks perception; opinions about �to drink� meaning) and significant differences arose in particular between generations (below or above 25 years old), between gender and between different types of alcohol consumer

    No full text
    Background: Eligibility criteria for blood donation require hemoglobin levels of &ge;12.5 g/dL for women and &ge;13.5 g/dL for men, and a platelet count of &ge;180 &times; 109/L. Screening methods before donation should ensure high accuracy, precision, and ease in operation. We assessed the performance, precision, and repeatability of the Horiba Micros ES 60 (Horiba) compared to the Beckman Coulter DXH 800. Methods: Performance was compared by testing samples for each of the 11 devices across 6 sites in the Transfusion Service of Friuli Venezia Giulia Region, Italy. We measured precision by calculating the coefficient of variation (CV), concordance with &rho;-Pearson&rsquo;s correlation coefficient, and accuracy with F-tests. The intra-assay agreement was examined in the 11 devices, and repeatability was performed by using CV and the Kruskal&ndash;Wallis test. Results: The precision of Horiba was acceptable. Overall, &rho;-Pearson&rsquo;s coefficients indicated a strong correlation and positive relationship between all variables. The Bland&ndash;Altman plots showed that most of the differences lay within the limits of agreement. All CV were below the reference threshold for all the parameters. Finally, the Kruskal&ndash;Wallis test reported non-significant statistical differences for all parameters, except platelet count (p &lt; 0.000). Conclusions: Horiba is adequate for routine pre-donation screening. The intra-assay agreement further demonstrates the accuracy of the device

    Previous Humoral Immunity to the Endemic Seasonal Alphacoronaviruses NL63 and 229E Is Associated with Worse Clinical Outcome in COVID-19 and Suggests Original Antigenic Sin

    Antibody-dependent enhancement (ADE) of severe acute respiratory syndrome coronavirus-2 (SARS CoV-2) infection has been hypothesized. However, to date, there has been no in vitro or in vivo evidence supporting this. Cross-reactivity exists between SARS CoV-2 and other Coronaviridae for both cellular and humoral immunity. We show here that IgG against nucleocapsid protein of alphacoronavirus NL63 and 229E correlate with the World Health Organization’s (WHO) clinical severity score ≥ 5 (incidence rate ratios was 1.87 and 1.80, respectively, and 1.94 for the combination). These laboratory findings suggest possible ADE of SARS CoV-2 infection by previous alphacoronavirus immunity

    International audienceOur study aims at providing evidence on patterns of use of biologic drugs for psoriasis in Tuscany, Italy. We conducted a drug-utilization study based on administrative databanks of Tuscany (EUPAS45365) from 2011 to 2019. We selected new users of etanercept, infliximab, adalimumab, ustekinumab, or secukinumab between 1 January 2011 and 31 December 2016. We considered subjects with psoriasis and followed subjects until the end of the study period (three years after the first dispensation of biologic drug for psoriasis) or the patient’s death, whichever came first. We censored subjects for pregnancy or neoplasia. For each subject, we defined the state as the weekly coverage of one of the biologic drugs of interest. We then defined the switch as the change from a state to another one. A total of 7062 subjects with a first dispensation of a PSObio drug in the inclusion period was identified, and 1839 (52.9% female, 51.6 mean age) patients were included in the analysis. Among new users of adalimumab (N = 770, 41.9%), one third showed a continuous behaviour whereas the others moved to etanercept and ustekinumab. New users of etanercept (N = 758, 41.2%), had the highest proportion of switchers, with adalimumab most often being the second choice. New users of infliximab (N = 159, 8.6%) experienced the highest proportion of treatment discontinuation. The present study suggests that the majority of patients treated with PSObio drugs do not switch from one active ingredient to another. However, patients who started biological therapy with etanercept had the highest frequency of switching to other PSObio drugs, whereas those who started with secukinumab or ustekinumab had the lowest

    Measuring the Effectiveness of Safety Warnings on the Risk of Stroke in Older Antipsychotic Users : A Nationwide Cohort Study in Two Large Electronic Medical Records Databases in the United Kingdom and Italy

    INTRODUCTION: Safety warnings relating to antipsychotic-associated stroke among older persons in the UK and Italy were issued. However, the impact of these safety warnings on stroke risk has not been measured to date. OBJECTIVE: The aim of this study was to measure the change in stroke incidence after two safety warnings in both the UK and Italy. METHOD: A cohort study was conducted using electronic medical records representative of the UK (The Health Improvement Network) and Italy (Health Search-IQVIA Health LPD), containing data on 11 million and 1 million patients, respectively. After each drug safety warning, elderly antipsychotic new initiators were propensity-score matched 1:1:1 on antipsychotic initiators before any safety warning. Stroke incidence within 6 months of antipsychotic initiation, using an intention-to-treat approach, was the main outcome. RESULTS: In the UK and Italy, 6342 and 7587 elderly antipsychotic initiators were identified, respectively. A 42% stroke incidence reduction was seen in the UK after the first safety warning [42.3 (95% confidence interval (CI) 35.2-50.8) vs. 24.4 [95% CI 19.0-31.2] events per 1000 person-years (PYs)], while there was a 60% stroke incidence reduction after the second warning (16.9 [95% CI 12.2-23.4] events per 1000 PYs) compared to before the first warning. There was no significant reduction in stroke incidence in Italy. CONCLUSION: Antipsychotic safety warnings were followed by a reduction in stroke incidence among older antipsychotic users in the UK, but not Italy

    Purpose: Our purpose was to explore antidepressant drug (AD) prescribing patterns in Italian primary care. Methods: Overall, 276 Italian general practitioners (GPs) participated in this prospective study, recruiting patients >18 years who started AD therapy during the enrolment period (January 2007 to June 2008). During visits at baseline and 3, 6, and 12 months, data about patients' characteristics and AD treatments were collected by the GPs. Discontinuation rate among new users of AD classes [i.e., selective serotonin reuptake inhibitors (SSRI); tricyclics (TCAs); other ADs) were compared. Logistic regression analyses were performed to identify predictors of AD discontinuation. Results: SSRIs were the most frequently prescribed ADs (N = 1,037; 75.3 %), especially paroxetine and escitalopram. SSRIs were more likely to be prescribed because of depressive disorders (80 %), and by GPs (51.1 %) rather than psychiatrists (31.8 %). Overall, 27.5 % (N = 378) of AD users discontinued therapy during the first year, mostly in the first 3 months (N = 242; 17.6 %), whereas 185 (13.4 %) were lost to follow-up. SSRI users showed the highest discontinuation rate (29 %). In patients with depressive disorders, younger age, psychiatrist-based diagnosis, and treatment started by GPs were independent predictors of SSRI discontinuation. Conclusions: In Italy, ADs - especially SSRIs - are widely prescribed by GPs because of depressive/anxiety disorders. Active monitoring of AD users in general practice might reduce the AD discontinuation rate. © 2012 Springer-Verlag

    Plasma Torquetenovirus (TTV) microRNAs and severity of COVID-19

    No full text
    Background Torquetenovirus (TTV), a widespread anellovirus recognized as the main component of the healthy human virome, displays viremia that is highly susceptible to variations in immune competence. TTV possesses microRNA (miRNA)-coding sequences that might be involved in viral immune evasion. Among TTV-encoded miRNAs, miRNA t1a, t3b, and tth8 have been found in biological fluids. Here, the presence of TTV DNA and TTV miRNAs in the plasma of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-infected subjects was investigated to monitor the possible association with coronavirus disease 2019 (COVID-19) severity. Methods Detection of TTV DNA and miRNA t1a, t3b, and tth8 was investigated in plasma samples of 56 SARS-CoV-2-infected subjects with a spectrum of different COVID-19 outcomes. TTV DNA and TTV miRNAs were assessed with a universal single step real-time TaqMan PCR assay and miRNA quantitative RT-PCR miRNA assay, respectively. Results The TTV DNA prevalence was 59%, whereas at least one TTV miRNA was found in 94% of the patients tested. miRNA tth8 was detected in 91% of subjects, followed by miRNAs t3b (64%) and miRNAt1a (30%). Remarkably, although TTV DNA was unrelated to COVID-19 severity, miRNA tth8 was significantly associated with the degree of disease (adjusted incidence rate ratio (IRR) 2.04, 95% CI 1.14-3.63, for the subjects in the high severity group compared to those in the low severity group). Conclusions Our findings encourage further investigation to understand the potential role of TTV miRNAs in the different outcomes of COVID-19 at early and late stages
