Consumo de tabaco, alcohol y cannabis en adolescentes Castellano-Manchegos
2010
El objetivo del presente trabajo es conocer la prevalencia del consumo de drogas (tabaco, alcohol y cannabis) en adolescentes de la Comunidad Autónoma de Castilla-La Mancha. Para ello, se confeccionó un cuestionario ad hoc a través del cual se midieron los consumos de tabaco, alcohol y cannabis, así como diferentes variables de personalidad, escolares, familiares, cognitivas, de ocupación del tiempo libre, etc. La muestra está compuesta por 243 alumnos de 1º E.S.O. pertenecientes a cuatro colegios privados de la ciudad de Toledo. La media de edad es de 11,89 años y la distribución por sexos corresponde al 45,7% de chicos y al 54,3% de chicas. Nuestros resultados ponen de manifiesto que el t…
Inversión publicitaria de la industria del tabaco en revistas femeninas y juveniles de Chile 1996-2004
2010
El estudio tiene como objetivo describir las características de la inversión publicitaria de la industria del tabaco en el período 1996-2004 en revistas femeninas y juveniles en Chile. Material y método: estudio descriptivo. Se recoge la información sobre inversión publicitaria de la principal empresa productora de tabaco en Chile (Chiletabacos S.A.) y se analiza mensualmente, según medio de comunicación, entre los años 1996 y 2004. La información sobre inversión publicitaria se compró a MEGATIME, (www.megatime. cl), empresa que verifica la inversión en publicidad de distintas empresas en forma mensual. La información sobre público objetivo de revistas se obtuvo de la empresa IPSOS MEDIA (w…
Detection of an O-methyltransferase synthesising acetosyringone in methyl jasmonate-treated tobacco cell-suspensions cultures.
2013
Acetosyringone (3',5'-dimethoxy-4'-hydroxyacetophenone) is a well-known and very effective inducer of the virulence genes of Agrobacterium tumefaciens but the precise pathway of its biosynthesis in plants is still unknown. We have used two tobacco cell lines, cultured in suspension and exhibiting different patterns of accumulation of acetosyringone in their culture medium upon treatment with methyl jasmonate, to study different steps of acetosyringone biosynthesis. In the two cell lines studied, treatment with 100 mu M methyl jasmonate triggered a rapid and transient increase in acetovanillone synthase activity followed by a progressive increase in S-adenosyl-L-methionine: 5-hydroxyacetovan…
Influence of Puerperal Health Literacy on Tobacco Use during Pregnancy among Spanish Women: A Transversal Study.
2020
Background: Despite the fact that tobacco use during pregnancy produces adverse perinatal effects, some women continue to smoke. Health literacy (HL) is essential for health outcomes in adults. However, little is known about HL in pregnant women or postpartum women. The study aimed to analyse the relationship between the degree of HL of women during the early puerperium and tobacco use during pregnancy. Methods: A multicentre, descriptive, cross-sectional study was carried out with women in the early puerperium in a region of eastern Spain, between November 2017 and May 2018. Their HL level was obtained using the Newest Vital Sign (NVS) tool. Multivariate logistic models were adjusted to es…
Current active and passive smoking among adults living with same sex partners in Spain
2018
Objective: To assess the association between current active and passive tobacco smoking and living with a same-sex partner in Spain. Methods: We analysed data from two cross-sectional national surveys of the Spanish population 15 years and older (2011-Encuesta Nacional de Salud en España and 2014-Encuesta Europea de Salud en España). Analyses included only people living with their partner. Associations were calculated using multiple logistic regressions adjusting for gender, social class and age. Results: Current active and passive smoking were significantly associated with living with same sex partners (odds ratio: 2.71 and 2.88), and particularly strong among women. Conclusions: Spanish a…
Clinical features of oral lichen planus. A retrospective study of 65 cases
2010
Objectives: To describe the clinical features of patients diagnosed with oral lichen planus (OLP) and to establish the prevalence of its malignant transformation in our setting. Study design: A retrospective study was made of 65 patients clinically and histologically diagnosed with OLP in the Service of Oral Surgery (Dental Clinic of the University of Barcelona, Spain) in the period 1990-2005. A descriptive and bivariate statistical analysis was made. Results: The mean patient age was 59 years (SD ± 14.9). Most of the patients (61%) were women, and the most frequent location of the lesions was the buccal mucosa (90.8%). White forms of OLP were noted in 66% of the cases, and 46.2% of the pat…
Prenatal exposure to cooking gas and respiratory health in infants is modified by tobacco smoke exposure and diet in the INMA birth cohort study
2013
Background: Studies that have evaluated the association between exposure to gas appliances emissions at home with respiratory health in children obtained heterogeneous and limited results. The aim of this study is to analyze the association between the use of gas cooking at home during pregnancy and respiratory problems in children during their first year of life. Methods: In the years 2003 through 2008 pregnant women were enrolled in 4 Spanish areas and visited in different age-points following a common protocol. Outcomes studied (from a questionnaire) were any episode of lower respiratory tract infection (LRTI), wheezing, persistent cough, chestiness and otitis. The association between ex…
The symbiosis between Nicotiana tabacum and the endomycorrhizal fungus Funneliformis mosseae increases the plant glutathione level and decreases leaf…
2015
Over time, anthropogenic activities have led to severe cadmium (Cd) and arsenic (As) pollution in several environments. Plants inhabiting metal(loid)-contaminated areas should be able to sequester and detoxify these toxic elements as soon as they enter roots and leaves. We postulated here that an important role in protecting plants from excessive metal(loid) accumulation and toxicity might be played by arbuscular mycorrhizal (AM) fungi. In fact, human exploitation of plant material derived from Cd- and As-polluted environments may lead to a noxious intake of these toxic elements; in particular, a possible source of Cd and As for humans is given by cigarette and cigar smoke. We investigated …
Study of leurocyte telomere lenght and transcription in patients in the acute phase of myocardial infarction
2011
Atherosclerosis with cardiovascular complications remains today one of the leading causes of death in developed countries. In this context, development of new biomarkers of atherosclerosis has an important place. Objectives of these biomarkers are: • to identify populations most at risk of developing cardiovascular complications, • to stratify patient groups to optimize their clinical management and therapeutic, • to reveal new therapeutic targets in the treatment of the disease. In this context, we identified three biomarkers of interest, leukocyte telomere length (LTL) and level of expression of leukocyte genes c-Fos (involved in inflammatory processes and oxidative) and OGG1 (necessary r…
Solving gap metabolites and blocked reactions in genome-scale models: application to the metabolic network of Blattabacterium cuenoti
2013
Abstract Background Metabolic reconstruction is the computational-based process that aims to elucidate the network of metabolites interconnected through reactions catalyzed by activities assigned to one or more genes. Reconstructed models may contain inconsistencies that appear as gap metabolites and blocked reactions. Although automatic methods for solving this problem have been previously developed, there are many situations where manual curation is still needed. Results We introduce a general definition of gap metabolite that allows its detection in a straightforward manner. Moreover, a method for the detection of Unconnected Modules, defined as isolated sets of blocked reactions connect…
