RESUMO
La polifarmacia es un término que, si bien no existe un consenso, se considerará como el uso concomitante de cinco o más medicamentos ya sean recetados o no por un profesional. Con respecto a ésta, se ha visto que se ha acrecentado en los últimos años tanto en Chile como en el mundo. En la presente investigación descriptiva se realizó un análisis de la Encuesta Nacional de Salud de Chile (ENS) 2016-17 y se comparó con los resultados obtenidos en la Encuesta Nacional de Salud 2009-10 y con la Encuesta sobre Salud, Envejecimiento y Jubilación Europea para de esta forma realizar un recuento objetivo sobre el aumento de esta condición en Chile. Al caracterizar a los grupos más afectados, se vio que en Chile la mayor prevalencia se daba en población adulta mayor sobre 65 años, mujeres y personas con escolaridad menor a 8 años cursados. Esto da cuenta del nivel del problema y la necesidad de una visión médica holística para el especial abordaje de la multimorbilidad, pues la polifarmacia trae consigo a su vez riesgos para la salud como lo son el aumento de las reacciones adversas e interacciones medicamentosas, riesgo de hospitalización, mayor deterioro del estado funcional, incremento de alteraciones cognitivas y mayores costos monetarios para el sistema de salud.
Polypharmacy is a term that, although there is no official definition, is understood as the concomitant use of five or more medications, regardless of whether they are prescribed by a professional. Regarding this phenomenon, an increase can be observed in recent years both in Chile and on a global level. This present descriptive research draws on an analysis of the National Health Survey (ENS) from 2016-17 and a comparison with the National Survey of Health from 2009-10 and with Survey of Health, Ageing and Retirement in Europe in order to carry out an objective count on the increase of this phenomenon. When characterizing the most affected groups, this paper shows that in Chile the highest prevalence can be found in the older adult population over 65 years of age, women and people with less than 8 years of schooling. These results reveal the dimension of the issue, and the need for a holistic medical vision to pay particular attention to multiple morbidities since polypharmacy brings with it health risks such as increased adverse reactions and drug interactions, risk of hospitalization, further deterioration of functional status, increase in cognitive alterations and higher monetary costs for the health system

Autonomic and peripheral neuropathies are well-described complications in diabetes. Diabetes mellitus is also associated to central nervous system damage. This little-known complication is characterized by impairment of brain functions and electrophysiological changes associated with neurochemical and structural abnormalities. The purpose of this study was to investigate brain structural and ultrastructural changes in rats with streptozotocin-induced diabetes. Cerebral cortex, hypothalamus, and cerebellum were obtained from controls and 8 weeks diabetic rats. Light and electron microscope studies showed degenerative changes of neurons and glia, perivascular and mitochondrial swelling, disarrangement of myelin sheath, increased area of myelinated axons, presynaptic vesicle dispersion in swollen axonal boutoms, fragmentation of neurofilaments, and oligodendrocyte abnormalities. In addition, depressive mood was observed in diabetic animals. The brain morphological alterations observed in diabetic animals could be related to brain pathologic process leading to abnormal function, cellular death, and depressive behavioral.

Depression is frequently observed among patients with diabetes and depressive status has been associated to activation of inflammatory processes, suggesting a role of depression in the inflammatory events observed in diabetes. To test that proposal, it was studied the effect of depression induced by forced swimming test (FST) on the evolution of early diabetic nephropathy. Diabetes was induced by streptozotocin injection. Rats were submitted to FST for 15 days. Struggle time was determined during FST and motor activity previously to FST. Nitric oxide, malondialdehyde, reduced glutathione and catalase activity were measured in kidney homogenates by enzymatic and biochemical methods. Superoxide anion, monocyte/macrophage (ED-1 positive cells) and RAGE were determined by histochemical and immunohistochemical methods. Diabetic rats had decreased struggle time and locomotor activity at day 1 of FST. Both control and diabetic rats had those parameters decreased at day 15. Renal oxidative stress, RAGE expression and ED-1 cells were observed increased in diabetic animals. Those parameters were not significantly altered by FST. The depressive status does not alter oxidative and immune parameters during the early renal changes of diabetic nephropathy.
