Heterogeneity at the HLA-DRB1 locus and risk for multiple sclerosis.

2006

Variation in major histocompatibility complex genes on chromosome 6p21.3, specifically the human leukocyte antigen HLA-DR2 or DRB1*1501-DQB1*0602 extended haplotype, confers risk for multiple sclerosis (MS). Previous studies of DRB1 variation and both MS susceptibility and phenotypic expression have lacked statistical power to detect modest genotypic influences, and have demonstrated conflicting results. Results derived from analyses of 1339 MS families indicate DRB1 variation influences MS susceptibility in a complex manner. DRB1*15 was strongly associated in families (P=7.8x10(-31)), and a dominant DRB1*15 dose effect was confirmed (OR=7.5, 95% CI=4.4-13.0, P<0.0001). A modest dose effect…

The Protein Structure Context of PolyQ Regions.

2016

Proteins containing glutamine repeats (polyQ) are known to be structurally unstable. Abnormal expansion of polyQ in some proteins exceeding a certain threshold leads to neurodegenerative disease, a symptom of which are protein aggregates. This has led to extensive research of the structure of polyQ stretches. However, the accumulation of contradictory results suggests that protein context might be of importance. Here we aimed to evaluate the structural context of polyQ regions in proteins by analysing the secondary structure of polyQ proteins and their homologs. The results revealed that the secondary structure in polyQ vicinity is predominantly random coil or helix. Importantly, the region…

Hints from the Crowd: A Novel NoSQL Database

2013

The crowd can be an incredible source of information. In particular, this is true for reviews about products of any kind, freely provided by customers through specialized web sites. In other words, they are social knowledge, that can be exploited by other customers. The Hints From the Crowd HFC prototype, presented in this paper, is a NoSQL database system for large collections of product reviews; the database is queried by expressing a natural language sentence; the result is a list of products ranked based on the relevance of reviews w.r.t. the natural language sentence. The best ranked products in the result list can be seen as the best hints for the user based on crowd opinions the revi…

The evolutionary scenario of hepatocellular carcinoma in Italy: an update

2017

Background and aims Epidemiology of hepatocellular carcinoma is changing worldwide. This study aimed at evaluating the changing scenario of etiology, presentation, management and prognosis of hepatocellular carcinoma in Italy during the last 15 years. Methods Retrospective analysis of the ITA.LI.CA (Italian Liver Cancer) database including 5192 hepatocellular carcinoma patients managed in 24 centers from 2000 to 2014. Patients were divided into three groups according to the date of cancer diagnosis (2000-2004, 2005-2009 and 2010-2014). Results The main results were: 1) progressive patient aging; 2) progressive expansion of non-viral cases and, namely, of “metabolic” hepatocellular carcinoma…

Development and Validation of a New Prognostic System for Patients with Hepatocellular Carcinoma

2016

Background Prognostic assessment in patients with hepatocellular carcinoma (HCC) remains controversial. Using the Italian Liver Cancer (ITA.LI.CA) database as a training set, we sought to develop and validate a new prognostic system for patients with HCC. Methods and Findings Prospective collected databases from Italy (training cohort, n = 3,628; internal validation cohort, n = 1,555) and Taiwan (external validation cohort, n = 2,651) were used to develop the ITA.LI.CA prognostic system. We first defined ITA.LI.CA stages (0, A, B1, B2, B3, C) using only tumor characteristics (largest tumor diameter, number of nodules, intra- and extrahepatic macroscopic vascular invasion, extrahepatic metas…

Metabolic disorders across hepatocellular carcinoma in Italy

2018

Background: Metabolic disorders are well-known risk factors for HCC. Conversely, their impact on the natural history of HCC is not established. This study aimed at evaluating the impact of metabolic disorders on clinical features, treatment and survival of HCC patients regardless of its aetiology. Methods: We analysed the ITA.LI.CA database regarding 839 HCC patients prospectively collected. The following metabolic features were analysed: BMI, diabetes, arterial hypertension, hypercholesterolaemia and hypertriglyceridaemia. According to these features, patients were divided into 3 groups: 0-1, 2 and 3-5 metabolic features. Results: As compared with patients with 0-1 metabolic features, pati…

Evaluation of atezolizumab immunogenicity: Efficacy and safety (Part 2).

2022

Abstract Antibody therapeutics can be associated with unwanted immune responses resulting in the development of anti‐drug antibodies (ADA). Optimal methods to evaluate the potential effects of ADA on clinical outcomes in oncology are not well established. In this study, we assessed efficacy and safety, based on ADA status, in patients from over 10 clinical trials that evaluated the immune checkpoint inhibitor atezolizumab as a single agent or as combination therapy for several types of advanced cancers. ADA can only be observed post randomization, and imbalances in baseline prognostic factors can confound the interpretation of ADA impact. We applied methodology to account for the confoundin…

An international perspective on hospitalized patients with viral community-acquired pneumonia

2019

Background Who should be tested for viruses in patients with community acquired pneumonia (CAP), prevalence and risk factors for viral CAP are still debated. We evaluated the frequency of viral testing, virus prevalence, risk factors and treatment coverage with oseltamivir in patients admitted for CAP. Methods Secondary analysis of GLIMP, an international, multicenter, point-prevalence study of hospitalized adults with CAP. Testing frequency, prevalence of viral CAP and treatment with oseltamivir were assessed among patients who underwent a viral swab. Univariate and multivariate analysis was used to evaluate risk factors. Results 553 (14.9%) patients with CAP underwent nasal swab. Viral CA…

Wykorzystanie zasobów baz danych GIS na potrzeby analizy zróżnicowania obszarów wiejskich w aspekcie działań PROW = Application of GIS databases for …

2018

Realizacja działań w ramach Programu Rozwoju Obszarów Wiejskich (PROW) wymaga obiektywnego rozpoznania potrzeb ich wdrażania, w oparciu o wyniki analiz złożonych procesów przyrodniczych i ekono- miczno-demograficznych zachodzących w czasie i przestrzeni obszarów wiejskich. Wzrastająca funkcjonalność Systemów Informacji Geograficznej (GIS) oraz powszechna dostępność do informacji przestrzennej spowodowały, że bazy danych GIS i analizy geoprzestrzenne stały się skutecznym narzędziem wpierającym implementację działań PROW. Celem pracy jest przedstawienie możliwości wykorzystania danych geoinformacyjnych wybranych baz danych GIS do analizy zróżnicowania przestrzennego obszarów wiejskich wojewód…

Recuperación de la información científica en pediatría: una oportunidad para el Índice Médico Español

2004

Las bases de datos bibliográficas internacionales (Medline, Embase, Current Contents, etc.) son una de las principales fuentes de información en medicina. Dada la incompleta cobertura de revistas nacionales en estas bases de datos extranjeras, es importante conocer y utilizar también el Índice Médico Español (IME), pues éste incluye la mayor parte de las revistas biomédicas españolas de carácter científico (básicas, experimentales y clínicas), lo cual proporcionará unas reconocidas ventajas para autores y editores en España.Del total de revistas indexadas en algún momento en IME (461 revistas), las relacionadas con la pediatría constituyen el 5,2 % del total (24 revistas) con un total de 21…
