Hepatocellular Carcinoma Presenting at Contrast-Enhanced Multi–Detector-Row Computed Tomography or Gadolinium-Enhanced Magnetic Resonance Imaging as …
2012
OBJECTIVE: The objective of the study was to measure growth rate and to determine the optimal interval time for imaging follow-up of hepatocellular carcinomas (HCCs) presenting at multi-detector-row computed tomography (MDCT) or magnetic resonance imaging (MRI) as small, indeterminate lesions. METHODS: We included patients with cirrhosis with HCC initially presenting as indeterminate lesion of 2 cm or less at MDCT or MRI August 2005 to August 2009 and with available imaging follow-up. Measures of tumor growth included tumor volume doubling time (TVDT), tumor percentual diameter increase, and tumor percentual volume increase. RESULTS: We examined 48 patients (mean age, 64 years) with 69 HCCs…
Knowledge management effectiveness factors: the role of HRM
2005
PurposeWithin the search of the key factors that explain knowledge management (KM) effectiveness, this paper aims to advance a simultaneously conceptual and practical framework that links human resource management (HRM) and KM.Design/methodology/approachA literature‐based preliminary framework assumes that a number of critical KM characteristics and KM‐related human resource (HR) practices impact on KM effectiveness. Qualitative methods are used for data collection and analysis. Three knowledge‐intensive Spanish business units of multinational companies are the target case‐study settings.FindingsSystematic patterns are found regarding the impact of critical KM characteristics and KM‐related…
A Multicentre Pilot Study of a Two-Tier Newborn Sickle Cell Disease Screening Procedure with a First Tier Based on a Fully Automated MALDI-TOF MS Pla…
2019
The reference methods used for sickle cell disease (SCD) screening usually include two analytical steps: a first tier for differentiating haemoglobin S (HbS) heterozygotes, HbS homozygotes and β-thalassemia from other samples, and a confirmatory second tier. Here, we evaluated a first-tier approach based on a fully automated matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) platform with automated sample processing, a laboratory information management system and NeoSickle® software for automatic data interpretation. A total of 6701 samples (with high proportions of phenotypes homozygous (FS) or heterozygous (FAS) for the inherited genes for sickle h…
Dioxin emissions and soft-tissue sarcoma: results of a population-based case-control study.
2004
International audience; BACKGROUND: In 1998, the French Ministry of Environment revealed that of 71 French municipal solid waste incinerators processing more than 6 metric tons of material per hour, dioxin emission from 15 of them was above the 10 ng international toxic equivalency factor/m3 (including Besançon, emitting 16.3 ng international toxic equivalency factor/m3) which is substantially higher than the 0.1 international toxic equivalency factor/m3 prescribed by a European directive of 1994. In 2000, a macrospatial epidemiological study undertaken in the administrative district of Doubs, identified two significant clusters of soft-tissue sarcoma and non Hodgkin lymphoma in the vicinit…
Guidelines for the use and interpretation of assays for monitoring cell death in higher eukaryotes
2009
Cell death is essential for a plethora of physiological processes, and its deregulation characterizes numerous human diseases. Thus, the in-depth investigation of cell death and its mechanisms constitutes a formidable challenge for fundamental and applied biomedical research, and has tremendous implications for the development of novel therapeutic strategies. It is, therefore, of utmost importance to standardize the experimental procedures that identify dying and dead cells in cell cultures and/or in tissues, from model organisms and/or humans, in healthy and/or pathological scenarios. Thus far, dozens of methods have been proposed to quantify cell death-related parameters. However, no guid…
The EORTC computer-adaptive tests measuring physical functioning and fatigue exhibited high levels of measurement precision and efficiency
2013
Objectives: The European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Group is developing a computer-adaptive test (CAT) version of the EORTC Quality of Life Questionnaire (QLQ-C30). We evaluated the measurement properties of the CAT versions of physical functioning (PF) and fatigue (FA) and compared these with the corresponding QLQ-C30 scales. Study Design and Setting: Based on international samples of more than 1,000 cancer patients, we simulated CAT administration of varying numbers of items and compared the resulting scores with those based on all items in the respective item pools. Furthermore, the relative validity (RV) of CATs was compared with that of th…
Accounting Analysis of Economic Policy of Spain (2012)
2014
The analysis of economic policy is made through a new methodology using the information provided by businesses to the Bank of Spain. The financial statements are the result of economic and financial transactions in a year and show a behavior that is likely to be measured by applying the Edgeworth’s box for analysis. This means that it is possible to measure the response of firms against market disruptions through an accounting interpretation of the information contained in the financial statements. The indicators obtained through this methodology measure a position taken in the Edgeworth’s box. Consequently, the observations obtained are random and therefore may explain the evolution of the…
Vitronectin as a molecular player of the tumor microenvironment in neuroblastoma
2019
Background Vitronectin is a multifunctional glycoprotein known in several human tumors for its adhesive role in processes such as cell growth, angiogenesis and metastasis. In this study, we examined vitronectin expression in neuroblastoma to investigate whether this molecule takes part in cell-cell or cell-extracellular matrix interactions that may confer mechanical properties to promote tumor aggressiveness. Methods We used immunohistochemistry and image analysis tools to characterize vitronectin expression and to test its prognostic value in 91 neuroblastoma patients. To better understand the effect of vitronectin, we studied its in vitro expression using commercial neuroblastoma cell lin…
Ranking Series of Cancer-Related Gene Expression Data by Means of the Superposing Significant Interaction Rules Method
2020
The Superposing Significant Interaction Rules (SSIR) method is a combinatorial procedure that deals with symbolic descriptors of samples. It is able to rank the series of samples when those items are classified into two classes. The method selects preferential descriptors and, with them, generates rules that make up the rank by means of a simple voting procedure. Here, two application examples are provided. In both cases, binary or multilevel strings encoding gene expressions are considered as descriptors. It is shown how the SSIR procedure is useful for ranking the series of patient transcription data to diagnose two types of cancer (leukemia and prostate cancer) obtaining Area Under Recei…
Effect of an upright (vs. stooped) posture on interpretation bias, imagery, and emotions
2020
[EN] Background and objectives: Adopting an upright (vs. stooped) posture has been related to positive effects on emotional and cognitive processes. However, there is no evidence concerning the effect of posture on two key processes associated with the maintenance of depression: interpretation bias and vividness of mental imagery. The objectives were to investigate the effect of adopting an upright (vs. stooped) posture on interpretation bias and vividness of positive and negative mental imagery, and to explore the interplay between these processes and depression-related emotions. Methods: The sample consisted of 54 participants (M-age = 22.00, 64.8% women), who were randomly assigned to th…
