ABSTRACT
La enfermedad celiaca es la intolerancia alimentaria más común del mundo, alcanzando a un 1% de la población y su único tratamiento es una dieta libre de gluten. El objetivo del estudio, de tipo exploratorio y diseño descriptivo, es conocer la percepción que los adultos celiacos tienen sobre su alimentación, calidad de vida y socialización después de empezar el tratamiento. Se entrevistó a 8 celiacos entre 24 y 37 años. Los entrevistados describen una respuesta emocional ante su nueva alimentación, que abarca frustración, cansancio, alivio, tranquilidad, no siendo excluyentes entre sí. El tratamiento nutricional hace ganar habilidades como la cocina, lo que genera mayor consciencia sobre lo que se come. Extrañar la comida con gluten es transversal; hay quienes pueden manejarlo, otros quienes rompen el tratamiento. La calidad de vida se ve afectada por el mayor costo económico de alimentacion sin gluten, las enfermedades asociadas y los factores que facilitan la adherencia a la dieta. La socialización con el entorno es facilitada cuando al celiaco se le apoya en su tratamiento; el ocio se vuelve más escaso y difícil, llevando a la restricción social
Celiac disease is the most common food intolerance in the world, reaching a prealenve of 1% of the population and its only treatment is a gluten-free diet. The aim of the study, exploratory and descriptive design, is to know the perception that celiac adults have about their diet, quality of life and socialization after starting treatment. Eight celiacs between the ages of 24 and 37 were interviewed. The interviewees describe an emotional response to their new diet, encompassing frustration, tiredness, relief and calm. Nutritional treatment makes them gain skills like cooking, which raises awareness about what you eat. Missing gluten-food is cross-cutting, some can handle it, others break treatment. Quality of life is affected by the higher economic cost of gluten-free nutrition, associated diseases and factors that facilitate diet adherence. Socialization with the environment is facilitated when celiac people is supported in its treatment; leisure becomes scarcer and more difficult, leading to social restrictions

Despite the availability of multiple therapeutic approaches, diabetes mellitus with chronic hyperglycemia remains as the main cause of new cases of blindness and chronic renal failure in the western hemisphere. We herein review the molecular mechanisms by which chronic hyperglycemia causes retinopathy and nephropathy in type I and type 2 diabetic patients. Diabetic retinopathy develops silently along years or decades, producing symptoms only in its very ¡ate stages. Its slow development starts with the activation of aldose reducíase, shortly followed by the destruction of the retinal pericyte cells, and ends in sudden blindness when vitreous hemorrhage ensues. Nephropathy, on the other hand, centers its pathophysiology in the mesangial cell, that starts as a modified smooth-muscle cell, and turns itself into a myo-fibroblast, produces such amounts of cytoplasm and extracellular protein that strangulates the glomerular capillaries and causes renal failure. After a detailed review of the molecular mechanisms of the aforementioned complications, we conclude that, apart from directing our attention to the emerging medications that are being developed to block these molecular pathways, we should never abandon the struggle for improving the glycemic control of our diabetic patients.

Background: The Ministry of Health of Chile and selected obesity specialized centers implemented an interdisciplinary pilot program for overweight adults at risk of diabetes to decrease the risk of type 2 diabetes (T2D) and cardiovascular risk factors (CVRF). Aim To assess the results of this program. Patients and methods: Beneficiaries of the public primary health system aged 18-45 years, with a body mass index (BMI) 25-38 kg/m² and fasting blood glucose 100-125 mg/dL or with any direct family member with T2D, were recruited. During the four months of the study, they were scheduled for three physician visits, four dietitian consultations, 14 physical activity sessions and four group workshops (two with a psychologist or therapist). In fasting blood samples, at the beginning and at the fourth month, glucose, insulin and lipids were determined. The Homeostasis model assessment (HOMA) index was calculated. Results: Two hundred-seventy-six patients were recruited and 160 (141 women), completed the four months of follow up. In this subgroup, at the start and end of the intervention, a BMI equal to or greater than 30 kg/m² was observed in 69 percent and 52 percent of subjects respectively, a systolic blood pressure equal to or greater than 140 mm Hg was observed in 24 percent and 6 percent respectively, a diastolic blood pressure equal to or greater than 90 mm Hg was observed in 28 percent and 9 percent respectively, a blood glucose equal to or greater than 100 mg/dL was observed in 61 percent and 19 percent respectively, a plasma insulin equal to or greater than 12,5 fi Ul/rnl was observed in 49 percent and 34 percent respectively and a HOMA equal to or greater than 2.5 was observed in 63 percent and 42 percent respectively (all these comparisons are significant with a p <0.05). Conclusions: In those patients that completed the follow up period, this intervention induced a significant decrease of some CVRF, such as BMI, fasting glucose levels...
