Hidratación: importancia en algunas condiciones patológicas en adultos / Hydration: Importance in some pathological conditions in adults

Resumen Estar bien hidratado se relaciona con un estado adecuado de salud y bienestar; sin embargo ¿qué pasa en los pacientes adultos que tienen algún padecimiento como obesidad, diabetes mellitus tipo 2, hipertensión arterial, cardiopatía isquémica e insuficiencia cardiaca, alteraciones nefrológicas (insuficiencia, poliquistosis y litiasis renal), enfermedad pulmonar obstructiva crónica, dislipidemia, hiperuricemia o, bien, en adultos mayores y en el periodo perioperatorio, en donde hay pérdida del estado de salud o una necesidad diferente de hidratación y que requieren consumir bebidas no alcohólicas para tener un buen estado de hidratación sin alterar la evolución natural de estas condiciones? Algunos puntos y recomendaciones son: la carbonatación de las bebidas ofrece el beneficio de aumentar la saciedad y disminuir la ingesta energética, lo que puede contribuir a la pérdida de peso; el agua simple es la mejor fuente de hidratación en los pacientes diabéticos, sin embargo, otras fuentes de hidratación pueden ser el agua mineralizada, el agua mineral, la leche (de preferencia descremada), café y té sin azúcar o con edulcorantes no calóricos o bajos en calorías, así como cualquier bebida que los contenga; en pacientes con litiasis renal se recomienda ingerir 2.5 a 4 L de agua al día; las bebidas para deportistas pueden ser consumidas por pacientes hipertensos, siempre y cuando no excedan la cantidad de sodio recomendada por la Organización Mundial de la Salud. En conclusión, la hidratación juega un papel importante en la evolución de las enfermedades mencionadas.

Abstract Being well hydrated is related to an adequate state of health and well-being; however, what happens in those adult patients having some pathological conditions such as obesity, type 2 diabetes mellitus, high blood pressure, ischemic heart disease and heart failure, kidney diseases (renal failure, polycystic renal disease and renal lithiasis), chronic obstructive pulmonary disease, dyslipidemia, hyperuricemia, or in the elderly and in the perioperative period, where there is loss of health or a different need for hydration and require the use of non-alcoholic beverages in order to have a good state of hydration without altering the natural evolution of these conditions? Some key points and recommendations are: carbonation of beverages offers the benefit of increasing satiety and decreasing energy intake, which can contribute to weight loss; simple water is the best source of hydration in diabetic patients; however, other sources of hydration may be mineralized water, mineral water, milk (preferably non-fat), coffee and tea without sugar or non-caloric sweeteners or low-calorie, as well as any beverage containing them; in patients with renal lithiasis it is recommended to take 2.5 to 4 L of water per day; sports drinks can be consumed by hypertensive patients as long as they do not exceed the amount of sodium recommended by the World Health Organization. In conclusion, hydration plays an important role in the evolution of the pathologic conditions mentioned above.

[Consensus on Systemic Arterial Hypertension In México]. / Consenso de Hipertensión Arterial Sistémica en México.

This Consenso Nacional de Hipertensión Arterial Sistémica (National Consensus on Systemic Arterial Hypertension) brings together experiences and joint work of 79 specialists who have been in contact with the patient affected by systemic arterial hypertension. All concepts here presented were outlined on the basis of the real world practice of Mexican hypertensive population. The consensus was developed under strict methodological guidelines. The Delphi technique was applied in two rounds for the development of an appropriate statistical analysis of the concepts exposed by all the specialists, who posed key questions, later developed by the panel of experts of the Hospital de Cardiología, and specialists from the Centro Médico Nacional. Several angles of this illness are shown: detection, diagnosis, pathophysiology, classification, treatment and prevention. The evidence analysis was carried out using PRISMA method. More than 600 articles were reviewed, leaving only the most representative in the references. This document concludes with practical and useful recommendations for the three levels of health care of our country.

El análisis de la evidencia en la literatura se hizo utilizando el método de PRISMA para análisis de evidencia. Se revisaron más de 600 artículos y se dejaron en la bibliografía solo los más representativos. Este documento concluye con recomendaciones prácticas y de utilidad para los tres niveles de atención en salud de nuestro país.

Prevalence of nonalcoholic fatty liver disease in subjects with metabolic syndrome.

BACKGROUND: Nonalcoholic fatty liver disease (NAFLD) is the main cause of chronic liver disease. Metabolic syndrome (MetS) is an important predictor of NAFLD. Due to the increase of MetS in Mexico, a population-based cross-sectional study was conducted to estimate the prevalence of NAFLD. METHODS: One hundred ninety eight subjects with MetS were randomly selected from 1006 subjects and were invited to participate in the estimation of the prevalence of NAFLD. MetS was diagnosed following the criteria of the National Cholesterol Education Program (ATPIII-NCEP). Abdominal ultrasound was performed and left, right and caudate lobes were assessed according to size, echogenicity and hepatic borders. NAFLD was classified as mild, moderate and severe according to its echogenicity and visualization of the diaphragm and intrahepatic vessel borders. Prevalence of NAFLD was estimated with 95% confidence intervals (95% CI). RESULTS: Included in the study were 122 males (63.2%) and 71 females (36.8%). Prevalence of NAFLD was 82.9% (95% CI 77.6-88.2%). Prevalence was higher in males (p = 86.9%; 95% CI 80.9-92.9%) than in females (p = 76.1%; 95% CI 66.1-86.0%). There were no age differences. A higher proportion of patients had mild (52.3%) or moderate (22.3%) NAFLD and in only 16 patients was NAFLD severe (8.3%). CONCLUSIONS: The observed prevalence is alarming because 8/10 subjects with MetS had NAFLD in any stage. Health-related measures oriented to decrease the incidence of the MetS will have a favorable impact on the occurrence of NAFLD.

[Dietary trans fatty acids and its metabolic implications]. / Acidos grasos trans de la dieta y sus implicaciones metabólicas.

Fats are important nutrients in our diet, they have wide chemical properties that drive diverse metabolic effects. The trans fatty acids (TFA) are common compounds found in industrialized food, and recent research has shown they should be avoided due to their increased risk of cardiovascular disease (CVD). Some of the mechanisms involved include: reduction of c-HDL concentration, increase of low density lipoprotein, Lp (a), triglycerides; disturbance in prostaglandin balance and they may also promote insulin resistance. Obese subjects are prone to increased CVD risk associated with a state of chronic inflammation that can be worsened by TFA intake. The US population consumes approximately 5.3 g TFA per day (2.6% of their total energy intake and 7.4% of their fat energy). Recently, WHO recommendations suggest the intake of TFA should be lower than 1% of energy per day. Current fast food industry products have to decrease the amount of TFA content, and the experience from different countries shows that the elimination of trans fatty acids is a cost effective and feasible public health intervention.
