Se evaluaron 408 vacas y 142 novillas de 51 fincas seleccionadas aleatoriamente para determinar la presencia de anticuerpos contra N. caninum utilizando la técnica de ELISA indirecto. Mediante la odds ratio (OR), se evaluó la asociación de la prevalencia del parásito con factores de riesgo intrínsecos y extrínsecos a los animales. Se obtuvo una prevalencia por animal de 17,09% y una frecuencia de infección por fincas de 74,51%. La prevalencia se encontró asociada significativamente (P < 0,05), a la aptitud lechera (OR = 3,01), el patrón racial Bos taurus (OR = 4,29), el hecho de que el animal naciera en la propia finca (OR = 2,09), el consumo de alimento balanceado comercial (OR = 1,82) y la densidad mayor a 3 bovinos/Ha (OR = 1,91). Asimismo, fue hallada una asociación negativa con el patrón racial B. indicus (OR = 0,48) y el tamaño del rebaño mayor a 1.000 animales (OR = 0,33). No fue encontrada asociación significativa (P > 0,05), con el grupo etario, el número de partos, la presencia de perros y el origen del agua de bebida. Los resultados dan indicios de que en la región estudiada predomina la forma de transmisión vertical de N. caninum y que la prevalencia del parásito está influenciada por el sistema de producción.

Modern households encourage the substitution of vegetable for animal protein that severely affects them during scarcity season, particularly in small towns. Subsistence households have increased their legume intake when food was scarce. Seasonality had the largest effect on fruit availability. Unable to obtain enough protein and micronutrient rich foods when meats, fruits and vegetables become scarce, modern households make up for it by purchasing more fats and sugars, particularly in large towns with many grocery stores.

In this paper, we test the hypothesis that increased dependence on store bought foods has decreased seasonal changes in nutritional status and fat mass in Maya Children from Yucatan, Mexico. Methods: Weight for age (W/A), body mass index (BMI), and tricipital Skinfold z scores in children under the age of 10 years from 14 Maya rural towns with different degrees of development were compared longitudinally between scarcity and abundance seasons using a repeated measures analysis of variance. Height for age (H/A) z scores were also estimated. Results: Origin of food consumed corresponded to the town's degree of development. Nutritional status (W/Az) and adiposity, BMI, and tricipital z scores were significantly lower during the scarcity season in every community. W/Az, tricipital skinfold z, and H/Az scores were significantly higher in developed than in traditional towns, yet in both types of town W/Az and H/Az scores were below the WHO standard mean. Tricipital skinfold z score was only below the WHO standard amongst traditional towns during the scarcity season. Conclusions: Increased dependence on store foods failed to eliminate significant losses in body fat during the scarcity season. This failure may be affecting linear growth and promoting a thrifty phenotype that is seen in short and stocky individuals with a tendency to accumulate fat during abundance seasons.

Nevertheless, with traditional paper platforms it is practically impossible to fix most errors once the team is in the field. We present this case study of the nutritional ecology of rural Maya agriculturalists in Yucatan, Mexico, where we used touch screen tablet computers to digitize the answers to questionnaire surveys in real time and uploaded the data into a cloud-based database so that an offsite reviewer could correct random and consistent errors to improve the survey strategy as it developed. Our unit of analysis was the household whose ID is linked to nine Microsoft Access datasets with different aggregation levels. Each tablet has a screen form interface that guides each interviewer and reduces the possibility of mistakes. Every night the data are reviewed and uploaded to an institutional Microsoft OneDrive account. Before going into the field, a set of SPSSpc routines was prepared to export the datasets into SPSSpc files, which generated standardized output that were used to review the field data. We designed the first routines to search for missing cases. Once detected we looked for outliers, possible idiosyncratic differences between interviewers, and badly worded or designed fields that needed modification. In the end, the use of tablets by a field team, supported by a home office using cloud-based services, produced more reliable datasets that were ready to use almost immediately after returning from the field.

development of metabolic diseases in children and adolescents. To estimate the magnitude of the association between LBW
and IUGR with stunting or obesity among adolescents of two indigenous regions of the southern State of Chiapas, Mexico.
Subjects/methods We assessed a random sample of 303 adolescents selected from a birth cohort study (2003) conducted in
three hospitals serving urban and rural communities of Tzotzil-Tzeltal and Selva regions of Chiapas, Mexico. Sociodemographic
and anthropometric data from a sample of adolescents were correlated with their anthropometric data at birth
(weight, length for age). Logistic regression models were fitted to estimate odds ratios (OR) with 95% confidence intervals to
measure the magnitude of the association among the variables of interest. Models were adjusted for potential confounders.
Results In all, 12% of the sample had LBW and 28.8% IUGR. In total, 29% of adolescents were overweight/obese and 21%
were stunted. We found a statistically significant association between IUGR and a lower risk of being overweight/obese. A
higher probability for stunting was observed for LBW and IUGR.
Conclusions Stunting and overweight/obesity prevalence in this population of adolescents was high and was associated
with IUGR.

ARION 1, a liquid-propelled sounding rocket that is being developed by PLD Space, will lift off from the launch facilities in the South of Spain, concretely in Huelva. PLD Space, a Spanish start-up company established in 2011, has focused during the last years on the development of liquid-propulsion rocket engines that will power their rockets. After having tested successfully the first reusable rocket engine in their facilities at the airport of Teruel, PLD Space is concentrating its efforts on finalizing the entire ARION 1 sounding rocket. ARION 1, the first-ever reusable sounding rocket in Europe, will be able to provide around 4 min of microgravity conditions after reaching an apogee of 150 km in a nominal mission. This sounding rocket will have the capability of carrying up to 100 kg of payload, exposing scientific and technological payloads to low accelerations due to the liquid-propulsion technologies. With this paper, PLD SPACE wants to introduce the ARION 1 reusable sounding rocket, its capabilities as well as the advantages of a liquid-propelled-based sounding rocket with respect to other traditional solid-based sounding rockets. ARION 1 aims to be the sounding rocket reference in Europe, providing an affordable, flexible and simple microgravity platform to industry, space agencies, research centres and academia.

It first compares Height for Age (H/A), Weight for Age (W/A) and Body Mass Index (BMI) of children from three rural populations in Yucatan and Campeche, Mexico whose subsistence strategy had been altered to different degrees since 1970. It then compares BMI in adults, in the same regions, born before and after the alteration of their environment in the 1970's. Children in the least disrupted zone were taller and had lower BMI than children in the other two, but were not heavier than children from the richest disrupted zone. Children in the poorest disrupted zone were shorter and lighter than the rest. BMI in adult men was higher in the two most disrupted zones only in those cohorts that grew up after the traditional agricultural regime was altered. It is concluded that disruptions o...

Adolescent males with LEHs had lower BMIz scores while the reverse was true for females. BMI variation in males depended on their ability to satisfy an activity schedule with a high-energy demand that placed individuals who had early developmental problems at a disadvantage. Women on the other hand, while busy for longer hours than men, had more stationary activities and did not participate in sports. Systemic problems in utero and early childhood would therefore lead to a thrifty phenotype and, because they are stationary, these women tended to accumulate body fat faster than those without LEHs. That this happened both in Calakmul with a high fiber traditional diet and in Central Yucatan with a store-bought high carbohydrate diet suggests that labor allocation differences in agricultural populations in the Yucatan Peninsula put women at a disadvantage that may lead those with a thrifty phenotype to become overweight. That this process is much more evident in Central Yucatan than in Calakmul suggests that development will exacerbate the consequences of traditional gender inequalities already present in the agricultural household adaptive strategy.

Se utilizó la clasificación de estrategias campesinas de Gurri (2003) que las dividió en "tradicionales", familias extensas que basan su supervivencia en cultivos de subsistencia y actividades remuneradas, y "convencionales", familias nucleares que practican la agricultura como negocio. Se encontró que el impacto de la migración y las remesas varían por tipo de estrategia y por tiempo de recibir remesas. Ambas familias invierten la mayor parte de sus remesas en gasto de consumo y mejoras del hogar lo que contribuye a mejorar su nivel de vida inmediato, e invierten en capital humano a través del gasto en educación y salud. En el ámbito productivo, los primeros 5 años los campesinos tradicionales reorganizan el trabajo familiar y utilizan parte de las remesas para contratar mano de obra para reiniciar sus actividades agrícolas. Las familias convencionales por el contrario, abandonan la agricultura e invierten en ganado caprino. Después de cinco años de recibir remesas las familias tradicionales, al igual que los convencionales, aumentan las hectáreas en producción por año al convertir milpas en potreros para alimentar ganado. Las condiciones físicas del sur de Campeche en donde el acceso al agua es un factor limitante, hacen que el incremento en la actividad ganadera aumente la vulnerabilidad de todos los campesinos pues tiene impactos negativos globales en la capacidad de recuperación local de la tierra afectando indirectamente a familias que siguen tratando de llevar a cabo un esquema más sustentable y menos vulnerable.
