Genetically predicted longer telomere length is associated with increased risk of B-cell lymphoma subtypes
2016
International audience; Evidence from a small number of studies suggests that longer telomere length measured in peripheral leukocytes is associated with an increased risk of non-Hodgkin lymphoma (NHL). However, these studies may be biased by reverse causation, confounded by unmeasured environmental exposures and might miss time points for which prospective telomere measurement would best reveal a relationship between telomere length and NHL risk. We performed an analysis of genetically inferred telomere length and NHL risk in a study of 10 102 NHL cases of the four most common B-cell histologic types and 9562 controls using a genetic risk score (GRS) comprising nine telomere length-associa…
Development of certified environmental management in hospital and outpatient haemodialysis units
2015
Antecedentes: El impacto ambiental de la hemodiálisis es destacado. Está destacando la actividad en este sentido incluso a nivel bibliográfico. Los sistemas de gestión medioambiental (SGMA) voluntarios, Environmental Management and Auditing System (EMAS) e International Organization for Standardization (ISO 14001), son instrumentos destacados para la protección medioambiental junto a legislación, impuestos y beneficios fiscales. Objetivos: Conocer el grado de implantación de los SGMA en las unidades de hemodiálisis hospitalarias y ambulatorias del Sistema Nacional de Salud español, para disponer de un grupo de centros de referencia en gestión medioambiental en esta actividad sanitaria. Méto…
Functional categories of TP53 mutation in colorectal cancer: results of an International Collaborative Study.
2006
Item does not contain fulltext BACKGROUND: Loss of TP53 function through gene mutation is a critical event in the development and progression of many tumour types including colorectal cancer (CRC). In vitro studies have found considerable heterogeneity amongst different TP53 mutants in terms of their transactivating abilities. The aim of this work was to evaluate whether TP53 mutations classified as functionally inactive (< or=20% of wildtype transactivation ability) had different prognostic and predictive values in CRC compared with mutations that retained significant activity. MATERIALS AND METHODS: TP53 mutations within a large, international database of CRC (n = 3583) were classified ac…
Classification or non-classification of substances with positive tumor findings in animal studies: Guidance by the German MAK commission
2019
One of the important tasks of the German Senate Commission for the Investigation of Health Hazards of Chemical Compounds in the Work Area (known as the MAK Commission) is in the evaluation of a potential for carcinogenicity of hazardous substances at the workplace. Often, this evaluation is critically based on data on carcinogenic responses seen in animal studies and, if positive tumor responses have been observed, this will mostly lead to a classification of the substance under investigation into one of the classes for carcinogens. However, there are cases where it can be demonstrated with a very high degree of confidence that the tumor findings in the experimental animals are not relevant…
Geographical distribution and oncogenic risk association of human papillomavirus type 58 E6 and E7 sequence variations.
2013
Human papillomavirus (HPV) 58 accounts for a notable proportion of cervical cancers in East Asia and parts of Latin America, but it is uncommon elsewhere. The reason for such ethnogeographical predilection is unknown. In our study, nucleotide sequences of E6 and E7 genes of 401 HPV58 isolates collected from 15 countries/cities across four continents were examined. Phylogenetic relationship, geographical distribution and risk association of nucleotide sequence variations were analyzed. We found that the E6 genes of HPV58 variants were more conserved than E7. Thus, E6 is a more appropriate target for type-specific detection, whereas E7 is more appropriate for strain differentiation. The frequ…
International Union of Basic and Clinical Pharmacology. XCIV. Adhesion G Protein–Coupled Receptors
2015
The Adhesion family forms a large branch of the pharmacologically important superfamily of G protein-coupled receptors (GPCRs). As Adhesion GPCRs increasingly receive attention from a wide spectrum of biomedical fields, the Adhesion GPCR Consortium, together with the International Union of Basic and Clinical Pharmacology Committee on Receptor Nomenclature and Drug Classification, proposes a unified nomenclature for Adhesion GPCRs. The new names have ADGR as common dominator followed by a letter and a number to denote each subfamily and subtype, respectively. The new names, with old and alternative names within parentheses, are: ADGRA1 (GPR123), ADGRA2 (GPR124), ADGRA3 (GPR125), ADGRB1 (BAI1…
Testing the validity of the International Atomic Energy Agency (IAEA) safety culture model
2012
This paper takes the first steps to empirically validate the widely used model of safety culture of the International Atomic Energy Agency (IAEA), composed of five dimensions, further specified by 37 attributes. To do so, three independent and complementary studies are presented. First, 290 students serve to collect evidence about the face validity of the model. Second, 48 experts in organizational behavior judge its content validity. And third, 468 workers in a Spanish nuclear power plant help to reveal how closely the theoretical five-dimensional model can be replicated. Our findings suggest that several attributes of the model may not be related to their corresponding dimensions. Accordi…
La Asociación Europea contra la Poliomielitis y los programas europeos de vacunación
2012
La búsqueda de una respuesta europea al problema planteado por los brotes epidémicos de poliomielitis en las décadas centrales del siglo XX, desembocó en la creación de un organismo nuevo, la Asociación Europea contra la Poliomielitis en 1951. Los mecanismos de funcionamiento interno y las conexiones internacionales de dicha Asociación fueron subsidiarios de un determinado contexto socio-político que propiciaba este tipo de consorcios. Como muestra este trabajo, su labor en los dieciocho años de existencia fue decisiva para la articulación y el éxito alcanzado por las políticas sanitarias nacionales de inmunización masiva frente a la enfermedad.
Perspectives for the Treatment of Brucellosis in the 21st Century: The Ioannina Recommendations
2007
Policy Forum. Competing interests: ER has received research grants from Daiichi, Bayer, and Theravance and has served as a consultant to Pfizer, Theravance, Bayer, Wyeth, Rosetta, and BiondVax. Summary Points Brucellosis remains the commonest anthropozoonosis worldwide, and its treatment remains complex, requiring protracted administration of more than one antibiotic. In November 2006, a consensus meeting aimed at reaching a common specialist statement on the treatment of brucellosis was held in Ioannina, Greece under the auspices of the International Society of Chemotherapy and the Institute of Continuing Medical Education of Ioannina. The author panel suggests that the optimal treatment o…
Tumor necrosis factor (TNF) and lymphotoxin-a (LTA) polymorphisms and risk of non-hodgkin lymphoma in the interLymph consortium
2010
In an International Lymphoma Epidemiology Consortium pooled analysis, polymorphisms in 2 immune-system-related genes, tumor necrosis factor (TNF) and interleukin-10 (IL10), were associated with non-Hodgkin lymphoma (NHL) risk. Here, 8,847 participants were added to previous data (patients diagnosed from 1989 to 2005 in 14 case-control studies; 7,999 cases, 8,452 controls) for testing of polymorphisms in the TNF -308G>A (rs1800629), lymphotoxin-alpha (LTA) 252A>G (rs909253), IL10 -3575T>A (rs1800890, rs1800896), and nucleotide-binding oligomerization domain containing 2 (NOD2) 3020insC (rs2066847) genes. Odds ratios were estimated for non-Hispanic whites and several ethnic subgroups using 2-…
