Abstract: objective: determine vaccination coverage (vc) among adults 60 years of age and older (ep), for influenza, pneumococcal and tetanus vaccines, association with socio-demographic characteristics and heterogeneity at state level. material and methods: cross-sectional analysis based on information from 18 015 households visited in a national survey. general and vaccine information (self-report) for a randomly selected elder in each household is available. results: the national vc level was found to be 56.5% (±0.97) for influenza, 44.3% (±0.98) for pneumococcus and 61.8% (±0.96) for tetanus. the vc was significantly lower for ep without health social services and higher for women. almost 20.0% of ep recognized not having vaccines at all, due mainly that they didn't know it was a duty. conclusions: important improvements are shown in vaccination coverage among elderly in mexico. differentials suggest the need to intensify information campaigns and actions that could improve the accessibility to vaccines for this population.

Abstract: objective. to describe the patterns of persistent symptomatology in workers industrially exposed to organophosphate pesticides. material and methods. an observational, descriptive and cross-sectional study was performed. a questionnaire was applied to managers of a factory and to 89 workers, whose erythrocytic cholinesterase level was measured with the magnotti and lovibond method. information is described through rates, central tendency measures and dispersion. differences between groups were evaluated with the c2 test and the odds ratio was calculated. results. persistent symptomatology was found in 6.3 per 10 workers. 50% had six or more symptoms. no significant differences were found as to the risk of suffering from persistent symptomatology with respect to age, length of service or position at work. however, the highest proportion of symptoms was found in workers of 31 to 40 years of age, with 6 to 13 years of service, from the maintenance area, working as general operators or supervisors. among the 13 workers with previous intoxication, the prevalence of persistent symptomatology was 6.9 against 6.1 in workers who had not been intoxicated before. the risk of acute poisoning in workers with more than 14 years of service was 4 times greater than in workers with less than 14 years of service (p<0.005). average level of blood cholinesterase was normal (4.4 u/ml). conclusions. results show a relationship between exposure to organophosphate pesticides and presence of persistent symptoms. it is necessary to study the prevalence of this symptomatology in exposed and non-exposed populations.
Sintomatología persistente en trabajadores industrialmente expuestos a plaguicidas organofosforados

Salud Pública de México , 1999,
Abstract: Objetivo. Describir los patrones de ocurrencia de sintomatología persistente en trabajadores industrialmente expuestos a plaguicidas organofosforados. Material y métodos. Se realizó un estudio descriptivo, transversal y observacional. Se aplicó un cuestionario a las autoridades de la empresa y otro a 89 trabajadores a quienes se les determinó el nivel de colinesterasa sanguínea con los métodos Magnotti y Lovibond. Para la descripción de la información se elaboraron tasas, medidas de tendencia central y de dispersión. Para evaluar la diferencia entre grupos se utilizó la prueba ji2 y se calculó razón de momios. Resultados. La prevalencia de sintomatología persistente fue de 6.3 por cada 10 trabajadores; 50% tuvo seis síntomas o más. No se encontraron diferencias estadísticamente significativas en el riesgo de padecer sintomatología persistente de acuerdo con la edad, antigüedad, área de trabajo y puesto. No obstante, las proporciones más altas de síntomas se encontraron en los trabajadores de 31 a 40 a os de edad, con 6 a 13 a os de antigüedad en la fábrica, en el área de mantenimiento y en los puestos de obrero general y supervisor. En los 13 trabajadores que tuvieron antecedentes de intoxicación previa, la prevalencia de sintomatología persistente fue de 6.9 contra 6.1 de los que nunca se habían intoxicado. El riesgo de intoxicación aguda previa entre quienes tenían más de 14 a os de antigüedad en la empresa fue cuatro veces mayor que el de aquellos con menos de 14 a os (p< 0.05). El promedio del nivel de colinesterasa sanguínea fue normal (4.4 u/ml). Conclusiones. Los resultados muestran una relación entre la exposición a plaguicidas organofosforados y la presencia de síntomas persistentes. Luego entonces es necesario llevar a cabo investigaciones para determinar la prevalencia de esta sintomatología en distintas poblaciones expuestas y no expuestas.
Linchamientos en México y Guatemala: reflexiones para su análisis comparado
Carlos Antonio Mendoza Alvarado
El Cotidiano , 2008,
Abstract: En el caso de Guatemala, se han realizado estudios etnográficos, por parte de antropólogos y sociólogos, los cuales abarcan algunos casos específicos dentro del mismo país. También se han estudiado los linchamientos desde la perspectiva jurídica y política. Sin embargo, en la interpretación del fenómeno persiste un sesgo que ha obstaculizado el avance de la investigación: el prolongado conflicto armado interno que sufrió la sociedad guatemalteca sigue siendo la clave privilegiada de interpretación de todos sus problemas.

Biodrying under Greenhouse Conditions as Pretreatment for Horticultural Waste  [PDF]
Fabián Robles-Martínez, Elizabeth M. Silva-Rodríguez, Teodoro Espinosa-Solares, Belem Pi?a-Guzmán, Carmen Calixto-Mosqueda, Francisco J. Colomer-Mendoza, Enrique Durán-Páramo
Journal of Environmental Protection (JEP) , 2012, DOI: 10.4236/jep.2012.34038
Abstract: The biodrying process was studied as an alternative technology to reduce the mass and volume of horticultural waste. Four static piles were prepared inside a greenhouse: two containing whole waste and two consisting of shredded waste. All the piles were compared with a test pile containing whole waste and placed outside the greenhouse. In two cases, ventilation ducts were installed to improve aeration. Each greenhouse was 2.0 m wide, 3.5 m long and 1.16 m high. The air temperature and relative humidity were monitored both inside and outside the greenhouse. Mass, humidity, organic matter and total nitrogen in the waste were measured. Piles inside the greenhouse showed decreases of 80% and 75% in weight and volume, respectively, during the first 16 days. The data obtained in this work suggest that biodrying could improve the handling and transport of horticultural waste while also minimizing the impact of pollutants.

Abstract: Gastro-intestinal parasites of antelopes and buffalos (Syncerus caffer brachyceros) from the Nazinga game ranch in Burkina Faso. Parasitological survey done on the digestive tracts of antelopes [roans (Hippotragus equinus koba), hartebeests (Alcelaphus buselaphus major), defassa waterbucks (Kobus ellipsiprymnus defassa), oribis (Ourebia ourebi quadriscopa)] and buffalos (Syncerus caffer brachyceros) from the Nazinga game ranch in Burkina Faso allowed the identification of gastrointestinal parasites and the estimation of their prevalence and load. Nine different nematode species and three cestode species were found. Females and larvae of Cooperia were not identified up to the species level and were recognized as Cooperia spp. The nematode species found were: Haemonchus contortus, Trichostrongylus axei, Cooperia curticei, Cooperia spatulata, Skrjabinema sp., Trichostrongylus colubriformis, Trichuris ovis, Bunostomum phlebotomum, and Oesophagostomum sp. Cestodes’ species were: Moniezia expansa, Avitellina centripunctata, and Stilesia globipunctata. It was also noted without a thorough investigation the presence of Setaria labiato-papillosa in the abdominal cavity and paramphistomes in the rumen. In spite of the presence of parasites on the antelopes and buffalos, their killing out percentages (47.5 to 54.7%) indicated a good physical status.
