Abstract: introduction tobacco use is considered a worldwide public health problem because of the amount of death and disease it causes. the who reports that 30% of the adult population in the world are cigarette smokers, and that nearly five million of these will die within one year. prospective studies performed by the who show that if current tobacco use continues, in 2020 there will be 8.4 million deaths due to tobacco-related diseases every year; seven out of 10 of these deaths will occur in emergent countries, like mexico. more than 53000 tobacco users die every year in mexico because of tobacco-related diseases, and at least 147 of these die daily. data from the national addictions survey (nas) 2002 showed that 26.4% of the people between 12 and 65 years old were active tobacco consumers; this amounted to nearly 14 million individuals. of these, 7.1% were under 18 years old. the number of tobacco consumers in mexico has increased from nine million in 1988 to 14 million in 2002. according to the nas, 52% of the users smoke on a daily basis, and 61.4% of them began smoking when they were minors. to know the actual consumption levels, it is important to consider some factors: the number of cigarettes a person smokes, the different situations where a person smokes, and the social and physical consequences of smoking. thus, it would be possible to develop a consumer classification (i. e. soft consumers, mild consumers, and hard consumers). there may be numerous causes for a person to be ill. when speaking about the harmful effects of tobacco use, the literature is clear in stating that these begin with the first cigarette smoked. however, it can take up to 30 years for a consumer to notice the damage on his health after his/her consumption began; but within the first ten years there are problems in lung function and in physical endurance. when a person starts smoking there are acute and unpleasant side effects that are rarely associated with smoked tobacco use. consumption
Total Reflection X-Ray Fluorescence Analysis of Toxic Metals in Fish Tissues  [PDF]
Graciela Zarazúa, Karina Girón-Romero, Samuel Tejeda, Carmen Carreo-De León, Pedro ávila-Pérez
American Journal of Analytical Chemistry (AJAC) , 2014, DOI: 10.4236/ajac.2014.512089
Abstract: The concentration of Cr, Ni, Cu, Zn, Hg and Pb, considered like toxic, was evaluated in fish tissues by means the total reflection X-Ray Fluorescence technique (TXRF). Grass carp (Ctenopharygodon idella) samples were collected from six regions of the Tepuxtepec Dam which was used as a water reservoir and fish production for the local population. Fish tissues: gills, liver, kidney and muscle were analyzed in triplicate using a TXRF spectrometer “TX-2000 Ital Structures” with a Si(Li) detector and a resolution of 140 eV (FWHM) at Mn Kα and Mo tube (40 kV, 30 mA) with 17.4 KeV excitation energy. The mean concentration of metals in tissues decrease in the sequence: Kidney ≈ Gills > Liver > Muscle; the range of concentration for Zn was 26.68 - 816.67 mg/Kg followed by Cu: 1.18 - 35.81 mg/Kg, Cr: 1.10 - 9.30 mg/Kg, Ni: 0.40 - 3.80 mg/Kg, Pb: <0.02 - 1.92 mg/Kg and Hg: <0.03 - 1.97 mg/Kg. Chromium and mercury concentrations slightly exceed the limits for fish proposed by FAO/WHO and Mexican Legislation for human consumption in the edible parts of fish from each one of the regions of the Tepuxtepec Dam. The results show that metal accumulation in herbivorous carp tissues was higher in regions 1, 2 and 3 than the others, which could be due to the influence of Lerma River, one of the most polluted rivers of Mexico.
Upper lower Eocene calcareous nannoplankton from the Las Pocitas core (Tepetate formation), Baja California Sur, Mexico
García-Cordero, Erandi;Carreo, Ana Luisa;
Revista mexicana de ciencias geológicas , 2009,
Abstract: sixty species of calcareous nannoplankton from the tepetate formation were recovered from a drill hole near las pocitas, baja california sur. in spite of its low abundance and erratic distribution throughout the sedimentary column, the great amount of reworked species, as well as the absence of traditional index fossils representing the standard tropical biozonation, the co-occurrence of reticulofenestra dyctioda, rhabdosphaera crebra, r. pinguis, micrantholithus flos, pontosphaera pectinata and lanternithus minutus situates the studied stratigraphic column at the discoasteroides kuepperi cp12a subzone of okada and bukry, dated between 49.5 and 49 ma at the top of the upper lower eocene. the population structure as well as the lithological features of the sedimentary package, suggest a temperate open-sea deposit, which confirms interpretations based on other marine fossils at arroyo datilar, el conejo, salada, colorado y las pocitas, where rocks of the lower middle eocene tepetate formation crop out.

Open Journal of Preventive Medicine (OJPM) , 2011, DOI: 10.4236/ojpm.2011.13023
Abstract: Objective: The purpose of this study was to identify the best predictors of dyslipidemias in Mexican obese children using different anthropometric and body composition measurements. Methods: In an observational, cross-sectional study, 905 children from 5 schools were measured for weight, height, waist and hip circumference, and triceps and subscapular skinfolds. A fasting blood sample was taken from a random sub-sample of 306 children to determine lipid profile. Abnormal total cholesterol, LDL, HDL, triglycerides, total cholesterol to HDL ratio, and LDL to HDL ratio, were determined. Logistic regressions and ROC analysis were carried out to determine the best anthropometric predictors of these risk factors. Results: Prevalence of elevated total cholesterol, triglycerides and LDL cholesterol was 14%, 56% and 58%, respectively. In logistic regressions, BMI and triceps skinfold had the highest odds ratios to predict elevated total cholesterol (1.05, 95%CI: 0.97 - 1.14; 1.07, 1.01 - 1.13, respectively), triglycerides (1.19, 1.11 - 1.27; 1.12, 1.08 - 1.17, respectively), LDL cholesterol (1.11, 1.04 - 1.18; 1.09, 1.05 - 1.14, respectively), total cholesterol to HDL ratio (1.06, 1.00-1.14; 1.07,1.03-1.12, respectively) and LDL to HDL ratio risk (1.08,1.01-1.15; 1.07, 1.03-1.12, respectively). After BMI and triceps skinfold, subscapular skinfold also predicted dyslipidemias, except for low HDL; both skinfolds had a narrower odds ratio confidence interval than BMI. In ROC analysis, subscapular skinfold was the best predictor of elevated triglycerides with an AUC ≥ 0.7. Conclusion: Anthropometric measurements are not strongly associated with dyslipidemias in Mexican children. However, since triceps and subscapular skinfolds were better predictors than other anthropometry measures, they may be a simple way to predict dyslipidemias in Mexican children.

Revista chilena de infectología , 2012,
Abstract: Introducción: Las enfermedades transmitidas por alimentos (ETA) han aumentado considerablemente. Objetivo: Reportar un grave brote de ETA destacando la importancia de la notificación precoz para la activación del sistema de vigilancia epidemiológica. Resultados: Durante febrero de 2011 se observó un brote de Salmonella Enteritidis. Un 31,6% de los casos fueron atendidos en un mismo servicio de urgencia, donde todos requirieron la administración de fluidos endovenosos y 41,7% fueron hospitalizados por deshidratación grave. El 45,5% de los casos necesitó de una segunda consulta para ser diagnosticados correctamente. Discusión: La identificación de pacientes integrantes de un brote de ETA es difícil en los servicios de urgencia y los médicos sub-reportan los casos, retrasando al sistema de vigilancia epidemiológica. Conclusiones: Junto con brindar un adecuado tratamiento, los médicos deben estar capacitados para reconocer las ETA y comunicar tempranamente la sospecha de un brote para prevenir nuevos casos en la comunidad.
