Jaime Carranza-Madrigal, Sonia M. López-Correa, Jesús Alveano-Hernández
International Journal of Clinical Medicine (IJCM) , 2011, DOI: 10.4236/ijcm.2011.22020
Abstract: Background. This study estimated the prevalence of depressive symptoms among cardiometabolic department patients in México. Methods. To identify patients with depressive symptoms, we used the Beck’s Depression Inventory (BDI). We analyzed data from consecutive adult patients who attended during a year to a Cardiometabolic Department in México and described the demographic, metabolic and vascular status differences between depressive and non-depressive patients. The estimates are based on a total of 180 patients aged 22 to 83 years. Results. There was a depressive symptoms prevalence rate of 60.5%. Compared with non-depressive patients, depressive patients were more likely to be obese, and to have dysglucemia, hypercholesterolemia, hypoalphalipoproteinemia, microalbuminuria, high uric acid levels, carotid atherosclerosis, insulin resistance and metabolic syndrome. Conclusions. Our data suggest that prevalence of depression is elevated among cardiometabolic patients in México. Depression probably plays a role in cardiometabolic physiopathogenic, and must be intentionally assessed in cardiometabolic patients in order to treat it and to improve the cardiometabolic treatment response and adherence.
Averting Behavior Framework for Perceived Risk of Yersinia enterocolitica Infections
Sonia N. Aziz,Khwaja M. S. Aziz
Journal of Pathogens , 2012, DOI: 10.1155/2012/725373
Abstract: The focus of this research is to present a theoretical model of averting actions that households take to avoid exposure to Yersinia enterocolitica in contaminated food. The cost of illness approach only takes into account the value of a cure, while the averting behavior approach can estimate the value of preventing the illness. The household, rather than the individual, is the unit of analysis in this model, where one household member is primarily responsible for procuring uncontaminated food for their family. Since children are particularly susceptible and live with parents who are primary decision makers for sustenance, the designated household head makes the choices that are investigated in this paper. This model uses constrained optimization to characterize activities that may offer protection from exposure to Yersinia enterocolitica contaminated food. A representative household decision maker is assumed to allocate family resources to maximize utility of an altruistic parent, an assumption used in most research involving economics of the family. Yersiniosis remains a public health hazard due to exposure to contaminated food and human to human or zoonotic infections. Yersinia enterocolitica is an important cause of yersiniosis in humans and animals; its epidemiology remains yet to be fully understood and exposure to it is a growing food safety concern [1–5]. There are a number of recent reviews published on specific aspects of Y. enterocolitica, and while some of these studies investigate incidence rates, true incidence in developed and developing countries remain unknown [1, 6–10]. One of the most frequent outcomes of Y. enterocolitica is possibly diarrhea as exemplified by a study in Poland [11]. A study on methods of monitoring trends in incidence of foodborne diseases in the United States is a welcome instrument in the estimation of incidence of Y. enterocolitica and other pathogens [12]. Studies of incidence, combined with studies investigating behaviors of individuals responding to information of incidence and risk levels of Y. enterocolitica can be useful for public health mitigation policies. In this paper we discuss a behavioral model with a focus on avoiding health hazards associated with exposure to Y. enterocolitica. The paper is theoretical and the conceptual model presented here is not showcased with data. The theoretical framework easily lends itself to application subject to availability of secondary data. One major thrust of the theoretical discussion revolves around the heuristic notion “an ounce of prevention is worth a pound of

Abstract: Para analizar los resultados perinatales en relación con la menarquía en la adolescencia, se realizó una investigación prospectiva, transversal y analítica en el hospital universitario "Abel Santamaría", entre el 1ro. de enero y el 30 de abril de 2003. El universo del estudio estuvo integrado por todas las gestantes que parieron en el período analizado y la muestra quedó conformada por todas las adolescentes que parieron en dicho periodo. Se constituyeron 2 grupos, el I integrado por las adolescentes que el intervalo de tiempo entre la menarquía y el parto fue menor de 5 a os y el grupo II formado por adolescentes en que éste fue superior o igual a 5 a os. Se analizaron diferentes variables de la madre, el nacimiento y el recién nacido. El análisis estadístico se realizó por la frecuencia porcentual y el test de Chi cuadrado con diferentes niveles de significación. Se obtuvo relación altamente significativa entre las enfermedades propias y asociadas con el embarazo, la escasa ganancia de peso durante la gestación, la inducción del parto, la cesárea y el bajo peso al nacer, con el grupo I. Se concluye que la adolescente que tiene su parto con un intervalo inferior a 5 a os entre la menarquía y el nacimiento de su hijo se considera un factor de riesgo para que se produzcan alteraciones perinatológicas.

Abstract: Agricultural products certified as organic and free of pesticides cannot use synthetic chemicals in the production process. In this context, the search for new natural products appears as an alternative to the use of conventional pesticides, aiming to combat agricultural diseases. Menthol is a natural product obtained from plants that has importance in different branches of industry, mainly due to the feeling of freshness it provides in contact with skin and mucous. Menthol (70% - 90%) is the main compound of the menthol mint essential oil, followed by menthyl acetate (7% - 12%), which is an indicator of maturation. There are references to the period of maturation of menthol mint essential oil corresponds the period of flowering, on the other hand, are also presented evidence that the maturation of menthol mint essential oil is controlled by leaf expansion, namely with the physiological age of each leaf. Besides evaluating the essential oil production and quality extracted by hydrodistillation of young leaves (3rd to 5th node) and adult (6th to 8th node), was also proposed in this work to study the effect of menthol mint essential oil on the development of fungi of agricultural significance and commercial seeds of lettuce and tomato. After the extraction of the essential oil, was noted that adult leaves presented a higher content of essential oil, combined with the best commercial quality, showing higher levels of menthyl acetate and menthol. The menthol mint essential oil exhibited average fungitoxicity and antigerminative activity on Fusarium oxysporum, Rhizoctonia solani and Sclerotium rolfsii. On the other hand, menthol and terpineol, two essential oil components, showed the maximum fungitoxicity activity under this species and no inhibitory effect on the germination of lettuce and tomato.

Abstract: the objective of this research was to evaluate the relationship between the total activity of carboxylesterase and the resistance of m. persicae populations to pirimicarb. the aphids were collected on potato plants in contenda and piraí do sul, pr and ibicoara, ba, brazil. for the bioassay, five replicates for each concentration were prepared with 10 aphids placed in plastic vials with a fine fabric mesh on the bottom, and dipped into pirimicarb concentrations (%) at 0.0031; 0.0062; 0.0125; 0.025; 0.05, and 0.1%, during 10 seconds, then dried on filter paper. after 1h inside a 25°c chamber, the aphids were examined under a stereomicroscope, recording the number of dead insects. the carboxylesterase activity was assessed by in vitro colorimetric technique. a simple correlation was established between the results of the lc50 bioassay and the frequency of m. persicae resistant variants. according to the absorbance level, the aphids were classified as variants s; s/r1 (s or r1); r1; r1/r2 (r1 or r2); r2 and r3, respectively susceptible; partially resistant, resistant and highly resistant. it was found a significant positive correlation between the lc50 and the frequency of r2 forms and a significant negative correlation between lc50 and the frequency of s and s/r1 forms. the colorimetric data supported the bioassay results, indicating that the bioassay was precise enough to determine either populations with high frequency of susceptible individuals or population with high proportion of resistant and highly resistant individuals.

Abstract: insecticide bioassays associated with colorimetric testes were used to determine the diagnostic concentrations of pirimicarb for insecticide resistance detection in myzus persicae populations from potato crops. the aphids were randomly collected on potato plants of commercial crops in curitiba, piraí do sul and contenda, in paraná state and ibicoara in bahia state, from 1994 to 1996. the lc50 was estimated by submitting the aphids to bioassay with increasing concentrations of pirimicarb. dead and live aphids from the 0.0125; 0.025; 0.05 and 0.1% (g/100ml) insecticide treatments were frozen after one hour of the bioassay and submitted to the evaluation of total esterase by colorimetric assays. mortality was low at 0.0125%, but at 0.1% it reached 100% of the populations; thus, indicating that the diagnostic concentration is within this range. a significant difference was found between mortality caused by 0.025 and 0.05% pirimicarb in the same population, but not between populations collected from different areas. the 0.05% primicarb concentrations caused mortality of nearly 50% of high resistant individuals (r2), 72.0%of the moderately resistant populations (r1) and 89.7% of susceptible ones (s). the determination of this diagnostic concentration is useful for m. persicae resistance management programs because all individuals can be tested at this single appropriate concentration and low resistance frequencies can be detected in the population.
Efeito da aplica??o de pirimicarbe sobre popula??es de campo de Myzus persicae (Sulz.) (Homoptera: Aphididae) com diferentes níveis de esterases

Abstract: the frequency and intensity of myzus persicae (sulz.) resistance were studied using bioassays and biochemical tests in two potato crops in ibicoara, bahia. both areas received several insecticide applications which failed to control m. persicae. by the end of the crop season, one of the areas received two applications of pirimicarb and the other was not sprayed. six samples of 700 aphids each were randomly collected before and after the pirimicarb applications, with an interval of four days. specimens of m. persicae were also collected from isolated potato plants. at the laboratory, the samples were characterized by the cl50 based on insecticide bioassays and by total esterase activity using colorimetric assays. after the pirimicarb applications, the susceptible (s), the moderate resistant (r1) and mixed s/r1populations presented decreasing resistance frequencies (from 36.6 to 9.9; 12,0 to 7.5 and 11.4 to 5.9%, respectively). on the other hand, high resistant individuals (r2), extremely resistant (r3), and mixed populations of r1/r2 had increasing frequencies (from 17.7 to 36.7%; 2.3 to 9.1%, and 20.0 to 30.8%, respectively). the survival of s individuals was probably due to their wandering behavior on the plants to avoid sprayed areas. all changes in frequency were reflected in the lc50 and in the resistance ratio (rr). in the pirimicarb untreated area, high frequencies of r2, r3 and r1/r2 were observed. high frequency and resistance intensity of m. persicae in areas under intensive insecticide applications can be related to the selection of resistant populations and due to the entrance of winged migrants from spontaneous plants, where the frequency of r2+r3 was 81.4%.
