No full textThe aim of this study was to evaluate body composition and metabolic features in women with nonhypersecretory adrenal cortical incidentaloma (AI) and women with Cushing's syndrome (CS) compared with healthy control (C) women matched for age, menopausal status, and body mass index. We examined 15 females with CS, 22 with AI, and 20 C. We evaluated anthropometric, hormonal, and metabolic parameters in all subjects. Body composition was measured by dual-energy x-ray absorptiometry for total body (TB); in addition, abdominal fat was measured between L2 and L4 vertebrae. Women with CS and AI were overweight; waist to hip ratio mean values showed that women with CS and AI had a central fat distribution. TB fat was significantly higher in CS than in C women, however, AI women also had high fat values. Abdominal fat was significantly more increased in CS than in AI and C women. Eighty percent of CS women and 50% of AI women were hypertensive. High density lipoprotein cholesterol levels were lower and triglyceride levels were higher in CS and AI women than in C. The area under the curve for glucose after oral glucose tolerance test was significantly higher in CS and AI than in C. AI had urinary free cortisol values slightly higher than C and than the normal range. In conclusion, these data indicate that AI are at an intermediate state between normal and pathological. These alterations suggest that a subtle cortisol hypersecretion is probably present in AI and it may be the factor promoting alterations of body composition and metabolic parameters

No full textThe Corporate Food Regime and Immigrant Farm Workers in California Strawberry Harvests
No full textThis article analyzes the growing role of multinational companies in agri-food chains and their impact on the structure of local production and agricultural labor through the case study of berries grown in the Oxnard, California, area and Mexican immigrant farm workers. She looks specifically at the strategic management of agreements on supply, agricultural technology, and land by commercial companies, together with the effects of partial harvest mechanization and the multi-level system of labor intermediation. The author observes how the evolution of agri-food capital, which according to the analysis of the food regime, constitutes a reorganization of capital in general, influences both the circulation of capital and the social relations of production. She has based her research on a combination of quantitative and, above all, qualitative, techniques. En este artículo se analizará el creciente papel de las compañías multinacionales en las cadenas agroalimentarias, con los impactos en la estructura productiva local y el trabajo agrícola, a través del estudio de caso de las bayas producidas en el área de Oxnard, California (Estados Unidos) y los jornaleros inmigrantes procedentes de México. Se profundizará en la gestión estratégica de los convenios de suministro, de la tecnología agraria y de los territorios por parte de las compañías comerciales, junto a los efectos de la parcial mecanización de la cosecha y el sistema multinivel de intermediación laboral. Se observará cómo la evolución del capital agroalimentario que, según el análisis del régimen alimentario (food regime), constituye una reorganización del capital en general, influye tanto en los procesos de circulación del capital, como en las relaciones sociales de producción. La metodología de investigación se ha basado en una combinación de técnicas cuantitativas y sobre todo cualitativas

Se observará cómo la evolución del capital agroalimentario, que constituye una reorganización del capital en general, ha determinado transformaciones en la cadena productiva y comercial de los frutos rojos, tanto en los procesos de circulación del capital como en las relaciones sociales de producción. La metodología de investigación se ha basado en una combinación de diferentes técnicas, cuantitativas y sobre todo cualitativas, que incluyeron análisis de datos secundarios y estadísticas, la observación directa, grupos focales y entrevistas semiestructuradas (55 en total)
