Estudio bibliométrico de la revista Nutrición Hospitalaria en el periodo 2001 a 2005: parte 2, análisis de consumo; las referencias bibliográficas.

OBJECTIVE To describe and assess the consumption of the information consulted and cited in the articles published in the journal Nutrición Hospitalaria for the period 2001--2005 by means of bibliometric analysis. METHOD Cross-sectional descriptive analysis of the results obtained from the analysis of the lists of bibliographic references of the articles published at Nutrición Hospitalaria. We studied the most cited journals, the signatures index, the type of document referred, the publication language, the distribution of geographical origin, and obsolescence and readiness index. We took into account all types of documents with the exception of Communications to Congresses. RESULTS 345 articles were published at Nutr Hosp, containing 8,113 bibliographic references, with a median of 18, a maximum of 136 and minimum of 0 BR per article. The mean (rate of publications per published article during the specified period) is 23.52 (95% IC 20.93-26.10) and the mean at 5% is 20.66 per article. The 25th and 75th percentiles are 6 and 32, respectively, the interquartile interval being 26 BR per document. The semi-period of Burton and Kebler is 7 years and the Price Index is 38.18%. CONCLUSION The bibliographic references, the consumption of information, of the articles published at Nutrición Hospitalaria present parameters similar to other journals on health science. However, good data on obsolescence are observed, which reveal the good validity of most of the references studied.

Compliance with dietary and nutrient recommendations in the European Prospective Investigation into Cancer and Nutrition (EPIC)-Granada cohort at recruitment

BACKGROUND: The overall intake of energy and nutrients in the Granada EPIC-cohort (European Prospective Investigation into Cancer and Nutrition) is examined in order to assess compliance with the Spanish Nutritional Objectives (NO) and the Recommended Intakes (RI). METHODS: During recruitment (1992-1996), 7,789 participants, aged 35-69, were asked about diet through a validated diet history questionnaire. Nutrient intake is compared to the NO and RI that were valid at that time. Risk of inadequate intake is estimated as the percentage of the sample with intakes: ≤ 1/3 RI (high risk), ≤ 2/3 RI- > 1/3 RI (moderate risk), ≤ RI- > 2/3 RI, > RI. Differences in intakes have been analyzed by sex and age, and by smoking status and BMI. RESULTS: The daily intake of nutrients did not meet the NO as the total contribution of energy from proteins and fats exceeded these guidelines. Whilst intake of most nutrients was above the RI, the amount of iron, magnesium and vitamins D and E provided by the diet was not enough to meet the RI: in women aged 20-49 years, about 55% were at moderate risk for iron inadequacy, and a 20% of women for magnesium. Both sexes were at high risk of inadequacy for vitamin D, although sunlight exposure may supply adequate amounts. Never smokers showed a higher compliance to the NO. CONCLUSION: At recruitment, the nutrient profile of the diet was unbalanced. The observed nutrient inadequacy for iron, magnesium and vitamin E might be attributed to inappropriate dietary habits, and may have implications for future disease risk.

Algoritmo para el diagnóstico precoz de la deficiencia de vitamina b12 en ancianos

BACKGROUND: The elderly population is particularly at risk for developing vitamin B12-deficiency. Serum cobalamin does not necessarily reflect a normal B12 status. The determination of methylmalonic acid is not available in all laboratories. Issues of sensitivity for holotranscobalamin and the low specificity of total homocysteine limit their utility. The aim of the present study is to establish a diagnostic algorithm by using a combination of these markers in place of a single measurement. METHODS: We compared the diagnostic efficiency of these markers for detection of vitamin B12 deficiency in a population (n = 218) of institutionalized elderly (median age 80 years). Biochemical, haematological and morphological data were used to categorize people with or without vitamin B12 deficiency. RESULTS: In receiver operating curves characteristics for detection on vitamin B12 deficiency using single measurements, serum folate has the greatest area under the curve (0.87) and homocysteine the lowest (0.67). The best specificity was observed for erythrocyte folate and methylmalonic acid (100% for both) but their sensitivity was very low (17% and 53%, respectively). The highest sensitivity was observed for homocysteine (81%) and serum folate (74%). When we combined these markers, starting with serum and erythrocyte folate, followed by holotranscobalamin and ending by methylmalonic acid measurements, the overall sensitivity and specificity of the algorithm were 100% and 90%, respectively. CONCLUSION: The proposed algorithm, which combines erythrocyte folate, serum folate, holotranscobalamin and methylmalonic acid, but eliminate B12 and tHcy measurements, is a useful alternative for vitamin B12 deficiency screening in an elderly institutionalized cohort.

Bacteriemia asociada a catéter epicutáneo en la unidad de cuidado intensivo neonatal de la Fundación Cardioinfantil

La bacteriemia asociada a catéter afecta a pacientes en las unidades de cuidado intensivo con una alta morbilidad, mortalidad y aumento de los costos al sistema de salud. Los recién nacidos son la población de más alto riesgo por el mayor uso de catéteres centrales. Objetivo: Caracterizar factores de riesgo para bacteriemia asociada a catéter en la Unidad de Cuidado Intensivo Neonatal de la Fundación Cardioinfantil entre 2005 - 2010 Materiales y método: Estudio descriptivo de corte transversal, incluyó todos los recién nacidos con diagnostico de bacteriemia asociada a catéter. Se analizó la información utilizando frecuencias y medidas de tendencia central. Resultados: Se encontraron 50 pacientes con diagnostico de bacteriemia asociada a catéter. 50% de género masculino, 52% con edad gestacional al nacimiento menor a 36 semanas y 24% con peso menor a 1500 gramos al momento de la inserción del catéter. La edad fue de 24.2 días al momento de la inserción del catéter. En el 66% de los pacientes el sitio de inserción fue el miembro superior, siendo el Sthaphylococcus Epidermidis el germen con el 50% de las bacteriemias. Conclusión: La bacteriemia asociada a catéter afecta paciente prematuros, de bajo peso sin diferencias en genero. La manipulación de dichos dispositivos, el sitio de inserción, el uso previo de antibióticos, la duración del catéter y el uso de nutrición parenteral son factores que están asociados al mayor riesgo de infección. Siendo el Staphylococcus Epidermidis el germen mas frecuente.

Uso de hidrolizado proteico en los pacientes de una unida de terapia intensiva neonatal

Introducción. La leche humana es el primer alimento escogido para alimentar a los recién nacidos (RN), especialmente a los prematuros (RNPT y a los de peso muy bajo (RNMBP). Cuando esta leche no está disponible, deben ser recetadas fórmulas especializadas, que promuevan un crecimiento y desarrollo adecuados. El uso de los hidrolizados proteicos (HP) en la UTI neonatal ha sido promovido, debido al riesgo potencial que los RNPT/MBP presentan, por la inmadurez gastrointestinal, problemas de absorción e intolerancia alimentaria. Sin embargo, tales formulaciones no fueran elaboradas para atender las necessidades específicas de estos niños, y pueden, cuando son utilizadas, ocasionar un déficit nutricional. Objetivo. Comparar la progresión de la nutrición enteral (NE) (a través de la oferta de volumen, calorías y proteínas), la evolución ponderal, y las complicaciones clínicas entre recién nacidos de peso muy bajo (RNPMB) alimentados con fórmula para prematuros (FP) e hidrolizado proteico (HP) en la UTI neonatal. Casuística y métodos. Fueran estudiados dos grupos de RNPMB: grupo 1:13RNPMB con edad gestacional media de nacimiento de 30 semanas, peso medio de nacimiento de 1 167 gramos, que recibieron FP. Grupo 2:8 RN con edad gestacional media de nacimiento de 29 semanas, peso medio de nacimiento de 1 141 gramos, alimentados con HP. Las ofertas de volumen, la de calorías y la de proteínas fueran diariamente calculadas para todos los niños en ambos grupos. La nutrición parenteral (NP) que complementaría a la terapia nutricional en las primeras semanas, también fue calculada. Los RNMBP fueron pesados diariamente, por la mañana, en balanza digital (escala de 10 g) debidamente calibrada. El peso medio diario fue calculado hasta el dia 15 de vida. Fueron construidas curvas de crescimento, a través del polinomio de segundo grado para ambos grupos. Para el análisis estadístico se utilizó el test de medias. Resultados. ) La oferta media de volumen, calorías y proteínas fue mayos en la primera semana en el grupo 2, pero de una forma no significativa (p=0.38; 0.34 y 0.05, respectivamente). En las semanas subsequentes, no hubo diferencias significativas en la progresión de NE entre los grupos. No fueron observadas complicaciones clínicas, sólo ocurrieron dos casos de distensión abdominal en el grupo 1, pero no fueron caracterizados como enterocolitis necrosante (ECN). No hubo diferencias estadísticas relacionadas con el aumento de peso entre los dos grupos durante el periodo de estudio; sin embargo, el grupo 1 presentó una tendencia de mejor evolución. conclusión. La prograsión de la NE fue semejante con la utilización de los dos tipos de fórmulas, no feron encontradas diferencias en el aumento de peso de los grupos, y no hubo complicaciones clínicas en ninguno de ellos. No hubo ventajas en el uso del HP en la UTI neonatal; por tanto, no está indicado para RNPMB, sin disfunción intestinal, debido a que su composición nutricional no prevé las necesidades de este grupo de niños

Regionalización del Cuidado Perinatal en Portugal - Resultados

Lo Servicio Nacional de Salud en Portugal fue criado en 1979, universal e gratis. Las primeras UCIN surgieran en 1980, en 1985 fue criada la Sociedad Portuguesa de Neonatología, en 1987 lo sistema de transporte neonatal, en mismo año fue nominada una Comisión de Peritos en Perinatología. En 1989 fue nominado el Comité Nacional de la Mujer y del niño y empezó la Reforma de los cuidados de salud perinatal. Era un programa de 9 años en etapas de 3 años que incluía el ccierre de Hospitales con menos de 1500 partos/año, categorización de los hospitales en niveles de cuidados e la creación de Unidades Coordinadoras entre Centros de Salud y Hospitales. Las UCIN y Intermedios neonatales fueran equipados y definido el número necesario de obstetras, pediatras y enfermeras e fue hecha formación en Cuidados Intensivos Neonatales. Los Centros de Salud no tienen partos e controlan el embarazo normal; los hospitales Nivel I no tienen partos; los de Nivel II tienen partos normales y de bajo riesgo, por lo menos 1500/año, obstetras, Unidad de Cuidados Intermedios, Pediatras con formación en neonatología, ventilación por períodos cortos. Los Hospitales de Nivel III tienen partos de bajo y alto riesgo, obstetras y neonatólogos, UCIN, formación en obstetricia y neonatología e investigación. Las UCIN tienen ventilación de longa duración, nutrición parenteral, cuidados de recién nacidos con menos de 1500g, condiciones quirúrgicas, son centros de enseñanza e investigación. Deben tener neonatólogos y pediatras con competencia en neonatología 24h por día, 1.5 camas /1000 partos, 1 enfermera para 2 logares de intensivos – 2,5 enfermeras por cada cama de intensivos - deben estar localizadas en maternidades con >3000 partos. Hay también reglas para translado para nível III pré-natal y pós-natal. Lo impacto fue que la tasa de partos hospitalares aumentó hasta 99% la mortalidad fetal e fetal tardia disminuiu hasta 3,7 e 2,5/1000 NV+MN, la mortalidad perinatal con más de 28 semanas para 4,6/1000 NV+ MN, la neonatal para 2,4/1000NV e la infantil para 3,6. Las mejores condiciones socioeconómicas y nivel de educación pueden justificar parte de estos resultados pero la organización de los cuidado perinatales fue ciertamente una grande razón de mejoría.

Candidemia em um hospital terciário brasileiro: incidência, freqüência das diferentes espécies, fatores de risco e suscetibilidade aos antifúngicos

São apresentados os resultados de estudo transversal e observacional sobre candidemia realizado no Hospital de Clínicas da Universidade Federal do Paraná. No período de janeiro de 2001 a dezembro de 2004, foram analisados 100 episódios de candidemia. A incidência foi de 1,27 por 1.000 internações, sendo Candida spp o oitavo agente mais isolado nas infecções da corrente sanguínea. A idade variou de 5 dias a 89 anos com uma média de 32 anos, 60% dos casos ocorreram em adultos (66% > 50 anos) e 40% em crianças (52% < 1 ano). Cinqüenta e nove pacientes estavam internados em enfermarias e 41 em unidade de terapia intensiva. Candida albicans foi a espécie mais (59%) freqüente, seguida por Candida tropicalis (15%), Candida parapsilosis (9%). As condições associadas mais (97%) freqüentes foram uso de antibióticos, cateter venoso central (77%), bloqueador H2 (57%), nutrição parenteral total (49%) internamento em unidade de terapia intensiva (41%). Dos 51 isolados testados, 3 de Candida glabrata apresentaram suscetibilidade dose-dependente ao fluconazol e eram resistentes ao itraconazol. Uma amostra de Candida krusei apresentou suscetibilidade dose-dependente ao fluconazol, e uma de Candida pelliculosa suscetibilidade dose-dependente ao itraconazol. Na população de estudo, 68% receberam tratamento antifúngico, no entanto a mortalidade foi de 56%.

Incompatibilidades Medicamentosas

Las incompatibilidades medicamentosas pueden ser fisicoquímicas o terapéuticas. Las incompatibilidades fisicoquímicas son interacciones que ocurren in vitro entre principios activos y/o entre un principio activo y otro componente del producto medicinal durante su preparación, almacenamiento y/o administración. Las incompatibilidades medicamento-medicamento, medicamento-excipiente, medicamento-envase, son algunas de las interacciones que pueden inducir cambios en las propiedades fisicoquímicas y en la estabilidad del producto y, por lo tanto, se puede afectar la biodisponibilidad del medicamento y como consecuencia directa el resultado de la terapia medicamentosa. El problema de las incompatibilidades se agudiza cuando se trata de mezclas intravenosas, o sea cuando se combinan dos o más productos estériles en un líquido para su posterior administración IV. (...) Objetivos generales: * Aplicación de conocimientos generales y fisicoquímicos a la predicción y detección de incompatibilidades en líquidos IV. * Racionalización y protocolización en la práctica hospitalaria de combinación de principios activos con otros agentes en la terapia IV. * Aplicación de conocimientos generales y fisicoquímicos a la predicción y detección de incompatibilidades en Nutrición Parenteral. Objetivos específicos: * Realizar estudios de compatibilidad en combinaciones de antibióticos utilizados para el tratamiento de infección mixta. Estos estudios se realizan en solución de dextrosa al 5% y solución de cloruro de sodio al 0.9%. * Realizar estudios de compatibilidad en Mezclas de Nutrición Parenteral. * Poder escribir un protocolo que contemple, técnicas básicas en la preparación, incompatibilidad y estudio de estabilidad, administración de las mezclas, seguimiento y controles de NP.

Dietoterapia en paciente con linfangiectasia intestinal primaria y ascitis quilosa de repetición.

OBJECTIVES Primary intestinal lymphangiectasia is a lymphatic system's disorder, where lymphatic drainage is blockaged. Clinically it produces malabsorption, protein-losing enteropathy, hypogammaglobulin in blood, and several degrees of malnutrition. Its treatment is not easy and includes dietetic-therapy and drugs. MATERIAL AND METHOD A 35-year-old-woman case report is exposed. She has recurrent chylosa ascites, requiring several admissions and evacuatory paracentesis. After food-fat was replaced by medium-chain triacyl-glicerol-enriched diet, a clinical, analytical and anthropometric improvement was demonstrated. CONCLUSIONS The major way of treatment in intestinal lymphangiectasia in this case is the employement of specific-diet and adaptaded-basic-food. It's difficult and high collaboration of the patient is required, being necessary medical revisions during the whole life, due to the not well known evolution of this long-standing disease.

Beneficios de la terapia cognitivo-conductual y la presoterapia en pacientes obesos: ensayo clínico aleatorizado

OBJECTIVE. The purpose of this study was to analyze change of lifestyle in obese patients with cognitive behavior therapy and acupressure. METHODS. An experimental study was performed with placebo control group. Forty patients were randomly assigned to intervention group (cognitive behaviour therapy + acupressure) and control group (information session). Outcome measure was a questionnaire for the assessment and quantification of obesity related lifestyles. Measures were performed at baseline and, after 3-months intervention. RESULTS. After 3 months of treatment, the intervention group showed significant differences (p<0.05) in weight loss, diet and physical activity. CONCLUSION. In the obese patient, cognitive behavior therapy and acupressure, it has lost at least three kilograms over three months and has changed lifestyles related to obesity.

Hábitos y estilos de vida modificables en niños con sobrepeso y obesidad.

INTRODUCTION In the prevention for being overweight and for obesity, much attention is given to the influence of dietary factors, making the joint evaluation with other modifiable factors necessary. OBJECTIVES The aim of this project is to study the association between modifiable factors (physical activity, sedentary lifestyle, and dietary habits) with the prevalence of being overweight or obese in the youth population. METHODS Cross-Sectional study of 1283 school children between the ages of 3 and 16 years old, with measurements of the MBI, dietary habits, physical activity, sedentary lifestyle and family history of being overweight. Physical activity measured in MET was classified according to Pate criteria. RESULTS 22.4% of the boys and 32.9% of the girls were overweight. The presence of a BMI>25 in parents multiplied by 2.4 the risk of being overweight in children (OR CI 95% 1.5-3.7). 63.6% of overweight boys meet physical activity recommendations compared with 52.2% of girls, although in their case, it was greater than the average (45%). Sedentary time was 141 minutes for men and 128 minutes for women, with more sedentary behaviors associated with being overweight, especially in girls over 12 years of age (66.7%). Consuming cereal (OR 0.8) and having five meals per day (OR 0.5) act as protective factors. CONCLUSIONS In subjects with overweight, the levels of physical activity are close to those recommended levels, so which the values of a sedentary lifestyle together with dietary habits (if the parents have overweight) acquire a new relevance in intervention strategies of this problem.

Life-style factors associated with overweight and obesity among Spanish adults

OBJECTIVES To assess the relationship between life styles and eating habits with the overweight and obesity prevalence in a Spanish adult population. METHODS A population-based, cross-sectional study conducted on 2640 subjects older than 15 years, in Cádiz (Spain). Surveys were conducted in subjects' homes to obtain life styles, eating habits, and anthropometric data. Logistic regression has been used to study the association between the life style variables and overweight and obesity. RESULTS Prevalence of overweight and obesity in Cadiz is 37% and 17%, respectively; higher in males and increases with age. BMI has an inverse relationship with educational level (PR = 2.3, 1.57-2.38). The highest levels of obesity are associated with daily alcohol consumption (PR = 1.39, 1.29-1.50), greater consumption of television,and sedentary pursuit (PR 1.5, 1.07-1.24). A lower prevalence of obesity is observed among those with active physical activity (10.9% vs 21.6%), with differences between sex. Following a slimming diet is more frequent in the obese and in women but dedicate more hours than men to passive activities. In men is greater the consumption of alcohol, high energy foods and snacks. Overweight and obesity is associated with the male sex (OR = 3.35 2.75-4.07), high consumption of alcohol (OR = 1.38 1.03-1.86) and watching television (OR = 1.52 1.11-2.07), and foods likes bread and cereals (OR = 1.47 1.13-1.91). Exercise activities is a protective factor (OR = 0.76 0.63-0.98). CONCLUSIONS Life styles factors associated with overweight and obesity present different patterns in men and women and is necessary to understand them to identify areas for behavioural intervention in overweight and obesity patients.

Influencia de la temperatura en la ingesta de pacientes hospitalizados.

BACKGROUND AND OBJECTIVES Prevalence of hyponutrition in hospitalized patients is very high and it has been shown to be an important prognostic factor. Most of admitted patients depend on hospital food to cover their nutritional demands being important to assess the factors influencing their intake, which may be modified in order to improve it and prevent the consequences of inadequate feeding. In previous works, it has been shown that one of the worst scored characteristics of dishes was the temperature. The aim of this study was to assess the influence of temperature on patient's satisfaction and amount eaten depending on whether the food was served in isothermal trolleys keeping proper food temperature or not. MATERIAL AND METHODS We carried out satisfaction surveys to hospitalized patients having regular diets, served with or without isothermal trolleys. The following data were gathered: age, gender, weight, number of visits, mobility, autonomy, amount of orally taken medication, intake of out-of-hospital foods, qualification of food temperature, presentation and smokiness, amount of food eaten, and reasons for not eating all the content of the tray. RESULTS Of the 363 surveys, 134 (37.96%) were done to patients with isothermal trays and 229 (62.04%) to patients without them. Sixty percent of the patients referred having eaten less than the normal amount within the last week, the most frequent reason being decreased appetite. During lunch and dinner, 69.3% and 67.7%, respectively, ate half or less of the tray content, the main reasons being as follows: lack of appetite (42% at lunch time and 40% at dinner), do not like the food (24.3 and 26.2%) or taste (15.3 and 16.8%). Other less common reasons were the odor, the amount of food, having nausea or vomiting, fatigue, and lack of autonomy. There were no significant differences in the amount eaten by gender, weight, number of visits, amount of medication, and level of physical activity. The food temperature was classified as adequate by 62% of the patients, the presentation by 95%, and smokiness by 85%. When comparing the patients served with or without isothermal trays, there were no differences with regards to baseline characteristics analyzed that might have had an influence on amount eaten. Ninety percent of the patients with isothermal trolley rated the food temperature as good, as compared with 57.2% of the patients with conventional trolley, the difference being statistically significant (P = 0.000). Besides, there were differences in the amount of food eaten between patients with and without isothermal trolley, so that 41% and 27.7% ate all the tray content, respectively, difference being statistically significant (P = 0.007). There were no differences in smokiness or presentation rating. CONCLUSIONS Most of the patients (60%) had decreased appetite during hospital admission. The percentage of hospitalized patients rating the food temperature as being good is higher among patients served with isothermal trolleys. The amount of food eaten by the patients served with isothermal trolleys is significantly higher that in those without them.
