Satisfacción con la enfermera en atención primaria: herramientas de medida y factores explicativos / Satisfaction with primary care nursing: Use of measurement tools and explanatory factors

Objetivos: Analizar las propiedades psicométricas de 2 herramientas de medida de la satisfacción con la atención recibida de la enfermera en atención primaria y estimar los valores de esta satisfacción y las características del paciente y el servicio asociadas con su variabilidad. Métodos: Los sujetos fueron elegidos aleatoriamente en 23 centros de salud de la Comunidad de Madrid. Se midió la satisfacción con los cuestionarios AMABLE y de Baker, cuyas propiedades psicométricas fueron evaluadas. Se recogieron variables sociodemográficas y otras relativas al estado de salud, o al proceso de atención. Se construyó un modelo explicativo mediante Generalized Estimating Equations. Resultados: Los 662 sujetos expresaron una satisfacción media de 4,95/5 (DE 0,25) con AMABLE y 4,83/5 (DE 0,42) con el cuestionario Baker. AMABLE se explicaba en una única dimensión (alfa Cronbach 0,85), y Baker en 3: cuidados profesionales (media 4,76 [DE 0,48], alfa Cronbach 0,74), profundidad de la relación (media 3,76 [DE 1,18], alfa Cronbach 0,73) y tiempo dedicado (media 4,42 [DE 0,86], alfa Cronbach 0,47). La edad, una mejor percepción del estado de salud y la consulta concertada por la enfermera se asociaban con una mayor satisfacción expresada. La atención en el domicilio, los ingresos hospitalarios, el retraso en la consulta, la familia más extensa o la renta familiar elevada se asociaban con una menor satisfacción. Conclusiones: La satisfacción con la consulta de la enfermera en atención primaria era muy alta y se asociaba con características personales y de la propia consulta. Las herramientas evaluadas eran adecuadas para medir este resultado (AU)

Objectives: This study aims to assess the psychometric properties of two measurement tools for patient satisfaction with nursing care in Primary Care, the satisfaction level, and the personal and consultation characteristics associated with its variability. Methods: Subjects randomly selected in 23 Health Care centres in the Community of Madrid were included. Satisfaction was measured by means of the AMABLE and Baker questionnaires, in which the psychometric properties were evaluated. Sociodemographic characteristics of the consultations, variables related to health status, and other related to the consultation process were collected. An explanatory model using Generalized Estimating Equations was constructed. Results: The 662 subjects expressed a mean satisfaction of 4.95/5 (SD .25) with AMABLE, and 4.83/5 (SD .42) with the Baker questionnaire. AMABLE had a single dimension (Cronbach's alpha .85), and Baker three: professional care (mean 4.76, SD .48 Cronbach's alpha .74), depth of relationship (mean 3.76, SD 1.18, Cronbach's alpha .73), and perceived time (mean 4.42, SD .86, Cronbach's alpha .47). Ageing, a better perception of health status, and appointments arranged by nurses were associated with higher expressed satisfaction. Home care, hospital admissions, delayed consultation, extended family, or high family income were associated with lower satisfaction. Conclusions: Satisfaction with nurse consultations in Primary Care was very high, and varied depending on personal characteristics and on the type of consultation. The assessed tools allowed this outcome to be measured properly (AU)

Inmigración y factores asociados con la lactancia materna. Estudio CALINA / Immigration and factors associated with breastfeeding. CALINA study

OBJETIVO: Identificar las características socioculturales, obstétricas y perinatales asociadas con la lactancia materna completa (LMC) durante 4 meses, en dependencia del origen materno. MATERIAL Y MÉTODOS: Estudio de una cohorte representativa de la población de lactantes aragoneses (n = 1.452). Se han evaluado las variables socioculturales, obstétricas y perinatológicas asociadas a la modalidad de lactancia materna, en dependencia del origen de la madre. RESULTADOS: La prevalencia de LMC en nuestro medio es más alta en las madres inmigrantes que en las de origen español. El 37,2% de las de origen español mantienen la LMC a los 4 meses frente al 43% de las inmigrantes (p = 0,039) (RR españolas/inmigrantes=0,76; IC del 95%, 0,58-0,99); a los 6 meses, esto ocurre en un 13,9% vs. 23,8%, respectivamente (p < 0,001) (RR españolas/inmigrantes=0,52; IC del 95%, 0,37-0,72). Los factores que se asocian a la LMC a los 4 meses son diferentes entre ambos grupos. Las madres de origen español tienen más edad (p = 0,002), nivel educativo (p = 0,001), paridad (p = 0,003) y mayor probabilidad de parto vaginal (p = 0,005), y sus hijos presentan mayores valores antropométricos al nacimiento. Sin embargo, en las madres inmigrantes, el mantenimiento de LMC se asocia a un mayor índice de masa corporal materno y a no trabajar fuera del domicilio. En ambos grupos, la LMC se mantiene con más frecuencia en aquellas madres que no fuman (p = 0,001). CONCLUSIONES: La prevalencia de LMC durante los primeros meses de edad es más alta en las madres inmigrantes que en las madres de origen español y los factores socioculturales, obstétricos y perinatales que se asocian a la misma son distintos en función del origen materno

OBJECTIVE: To identify socio-cultural, obstetric and perinatal characteristics associated with complete breastfeeding (CBF) during the first 4 months of age, depending on maternal origin. MATERIAL AND METHODS: Socio-cultural, obstetric and perinatal aspects associated with breastfeeding depending on maternal origin were evaluated in a longitudinal study in a representative infant population from Aragon (n = 1452). RESULTS: The prevalence of CBF was higher in immigrant mothers than in those from Spain. CBF was maintained in 37.2% of mothers from Spain at 4 months, compared with 43% of immigrants (P=0.039) (RR Spanish/immigrants=0.76; 95% CI: 0.58-0.99); at 6 months this occurred in 13.9% vs. 23.8%, respectively (P<0.001) (RR Spanish/immigrants=0.52; 95% CI: 0.37-0.72). The factors associated with CBF at 4 months are different between both groups. Mothers born in Spain are older (P=0.002), have higher academic level (P=0.001), greater parity (P=0.003), and a higher probability of vaginal delivery (P=0.005); and their children have the highest anthropometric values at birth. However, in immigrant mothers, the maintenance of CBF was associated with a higher maternal body mass index and with working at home. In both groups, CBF remains more frequently in those mothers who do not smoke (P=0.001). CONCLUSIONS: The prevalence of CBF during the first months of life is higher in immigrant mothers than in those from Spain, and socio-cultural, obstetric and perinatal factors are different, depending on maternal origin

Prevalencia de la lactancia materna durante el primer año de vida en Aragón. Estudio CALINA / Breastfeeding prevalence during the first year of life in Aragon. CALINA study

Objetivos: Estudiar la prevalencia actual de la lactancia materna (LM) hasta los 12 meses de edad en Aragón, analizando los aspectos demográficos, perinatales y sociales que la modifican. Material y métodos: Estudio observacional longitudinal en una cohorte representativa de la población de lactantes aragoneses, nacidos desde marzo del 2009 a marzo del 2010, y controlados hasta los 12 meses de edad (N=1.602). Se han evaluado sus variables obstétricas, perinatológicas y de alimentación. Resultados: La LM exclusiva o predominante fue superior al resto de modalidades de alimentación durante los 4 primeros meses de vida. El mantenimiento conjunto de la LM en cualquiera de sus modalidades fue del 82,5% al mes de edad, el 71,8% al tercero, el 54,3% al sexto y 27,8% al año. Las variables maternas que se asociaron significativamente al mantenimiento de la LM, tanto al mes como a los 6 meses de edad fueron: tipo de parto (mayor probabilidad si el parto es vaginal), el nivel de estudios (mayor probabilidad si tienen estudios superiores), la procedencia (mayor probabilidad en las madres de origen africano), la adiposidad (mayor probabilidad en las madres que tienen un peso adecuado o sobrepeso frente a las obesas) y no fumar durante la gestación. Conclusiones: La prevalencia de LM en Aragón durante los primeros 12 meses de vida es alta y ha aumentado respecto a los datos que previamente se disponían. La LM se mantiene en más de la mitad de los lactantes de 6 meses y en una cuarta parte al año de edad. Los condicionantes maternos que influyen significativamente en el inicio y mantenimiento de la LM en nuestro medio son el tipo de parto, el nivel de estudios, la procedencia (inmigración), la adiposidad y el hábito tabáquico (AU)

Objectives: To study the current prevalence of breastfeeding (BF) in Aragon (Spain) during the first 12 months of life, and analyse its demographic, perinatal and social influential factors. Material and methods: Obstetric, perinatal and feeding aspects were evaluated in a longitudinal and observational study, in a representative cohort of infant population from Aragon born between March 2009 to March 2010, controlled until 12 months of age (N=1.602). Results: Exclusive or predominant BF was more frequent than the rest of feeding modalities during the first 4 months of life. Maintenance prevalence of any BF modality was 82.5% at 1stmonth of age, 71.8% at 3rd, 54.3% at 6th, and 27.8% at 12 months of age. Maternal variables that were significantly associated with BF maintenance both at 1 and 6 months of age were: delivery modality (higher probability in case of vaginal delivery), academic level (higher probability if university studies), origin (higher probability in mothers from Africa), adiposity (higher probability of normal weight or overweight mothers compared with obese ones), and not to smoke during gestation. Conclusions: BF prevalence in Aragon (Spain) during the first 12 months of age is high and has increased compared with previous data. BF continues in more than half of infants at six months and in a quarter of infants at 12 months of age. Maternal factors that significantly influence BF initiation and maintenance are, delivery modality, academic level, origin (immigration), adiposity and smoking habit (AU)

Uso de sellantes de fosas y fisuras para la prevención de caries en población infanto-juvenil: revisión metodológica de ensayos clínicos / Use of pit and fissure sealants for preventing caries in child population: Methodological review of clinical trials

La caries dental es uno de los problemas más relevantes dentro del ámbito odontológico y de la Salud Pública. En Chile existe una alta prevalencia de caries en la población infanto-juvenil, siendo esta una de las prioridades de salud del país. Se constata la necesidad de utilizar métodos complementarios para su control. Los sellantes de fosas y fisuras representan una de las intervenciones preventivas más efectivas en odontología, siendo considerados como un aporte a la Salud Pública. Sin embargo, no existen evidencias consistentes acerca de su verdadera efectividad e impacto en la prevención de caries. Las inconsistencias encontradas podrían deberse a la presencia de sesgos o a la heterogeneidad de los estudios disponibles en la literatura. Así, se propone realizar una revisión sistemática con el fin de evaluar la calidad metodológica de los ensayos clínicos controlados que utilizan sellantes de fosas y fisuras. Se condujo una búsqueda de ensayos realizados entre 1990 y 2007, encontrándose trece que cumplieron con los criterios de inclusión y exclusión. Los estudios incluidos fueron obtenidos y evaluados por un único revisor. Se concluye que la evidencia que avala la utilización de esta intervención es metodológicamente muy pobre. Estos hallazgos debieran estimular a los profesionales a esclarecer la verdad referente a la efectividad de los sellantes, antes de aplicarlos indiscriminadamente. Se recomienda la realización de nuevos ensayos clínicos ejecutados con un adecuado diseño metodológico y de análisis estadístico, cuyos resultados sirvan como evidencia confiable para la toma de decisiones que guíen las políticas de Salud Pública.

Dental decay is one of the most important problems within the Public Oral Health. Chile has a high prevalence of decay among children and adolescents, being this issue one of the priorities of public health in the country. Taking into account this context, there is a necessity of using complementary methods for its control. Pit and fissures sealants represent one of the most effective preventive interventions in dentistry, being considered as a contribution to the public health interventions. Nevertheless, there are no consistent evidences about their true effectiveness and impact in the prevention of caries. These inconsistencies could be due to the presence of bias or the heterogeneity of the studies available in literature. Thus, we propose to make a review with the aim to evaluate the methodological quality of clinical trials using pit and fissure sealants. A search of studies between 1990 and 2012 was conducted and 18 clinical trials that fulfilled the inclusion and exclusion criteria were found. The studies included were obtained and evaluated by a single reviewer. This review concludes that the evidence that guarantees the use of this intervention is methodologically poor. These findings may stimulate the professionals to clarify the truth referring to the effectiveness of sealants, before applying it indiscriminately. The accomplishment of new clinical trials executed with an appropriate methodological design and statistical analysis is recommended, generating reliable results for the decision making that guides the Public Health Policies.

Aspectos sobre la medición del impacto de la caries dental en la calidad de vida de las personas: artículo de revisión / Bearing impact measure of the dental caries in the quality of life: review article

Objetivo: Determinar, mediante una revisión de literatura publicada, la existencia de estudios enfocados en la relación entre historia de caries y calidad de vida relacionada a salud oral (CVRSO) utilizando instrumentos validados. Material y Método: Artículo de revisión bibliográfica de literatura publicada los últimos diez años usando la base de datos MEDLINE. Dos revisores independientes recopilaron y analizaron los artículos en dos etapas: En una primera etapa fueron seleccionados aquellos artículos en que en su resumen relacionaran historia de caries y calidad de vida utilizando un instrumento de medición validado, excluyendo todos aquellos en que los individuos tuvieran alguna patología base que por si misma afecta su calidad de vida y artículos de validación. En una segunda etapa fue analizado el texto completo de los artículos previamente seleccionados, se aceptaron estudios experimentales y observacionales, se excluyeron artículos de revisión. Los desacuerdos fueron resueltos por consenso. Resultados: De un total de 311 artículos, 12 artículos relacionaban enfermedades orales y calidad de vida relacionada a salud oral siendo "historia de caries" uno más de los parámetros medidos y 6 artículos tenían como objetivo relacionar directamente "historia de caries" y "calidad de vida", en estos últimos las dimensiones más afectadas fueron: dolor dental, comer-masticar alimentos, lavarse los dientes y sonreír.

Aim: To determine, through a review of published literature, the existence of studies focused on the relationship between history of decay and quality of life related to oral health (QOLROH), using validated instruments. Material and Method: Literature review of reports published in the last ten years using the MEDLINE database. Two reviewers independently assessed and analyzed articles in two stages: In the first stage the articles whose abstract related dental caries and quality of life using a validated measurement instrument were selected, excluding those in which individuals had a systemic pathology affecting itself their quality of life, and excluding articles of validation. In a second stage the full text of the previously selected articles was analyzed, experimental and observational studies were accepted and review articles were excluded. Disagreements were resolved by consensus. Results: Out of a total of 311 articles, 12 articles connected oral diseases and quality of life related to oral health, being "history of decay" one more of the measured parameters and only 6 articles related directly "history of decay" and "quality of life". In the latter the most affected dimensions were: Dental pain, eat-chew food, brushing your teeth and smile.

Aspectos perinatales, crecimiento y tipo de lactancia de los nacidos pequeños para su edad gestacional / Perinatal aspects, growth and feeding of infants born small for gestational age

Introducción: El haber nacido pequeño para la edad gestacional (PEG) conlleva riesgos a corto y a largo plazo. El objetivo del estudio es describir las características perinatológicas y socioculturales, el patrón de crecimiento y el tipo de alimentación de los nacidos PEG en nuestro medio durante sus primeros 6 meses de vida. Materiales y métodos: Se ha evaluado durante 6 meses la antropometría y alimentación en una muestra de 1.596 lactantes representativa de la población aragonesa. Resultados: Las madres de los PEG (n=94) ganaron menos peso durante la gestación (10,5±5,8 vs 12,0±5,07kg; p=0,012), el embarazo duró menos (37,84±1,7 vs 39,06±1,6semanas; p<0,001) y se les realizaron más cesáreas (37,2 vs 20,5%; p=0,001). La talla de la madre fue menor en el grupo de PEG (1,61±0,58 vs 1,63±0,06 metros; p = 0,004), pero su índice de masa corporal fue similar. No se encontraron diferencias entre grupos en los aspectos sociales o culturales. Las madres de los PEG fumaron más durante la gestación (32,3 vs 18,5%; p = 0,003) (RR = 1,92; IC 95%: 1,31-3,02). Los PEG mantuvieron un menor peso y longitud durante los 6 primeros meses de vida y la ganancia ponderal mensual fue similar al resto. La prevalencia de lactancia materna fue menor en los PEG, 54,9 vs 68,2% a los 4 meses (RR=0,58; IC 95%: 0,38-0,89). Conclusión: En los nacidos PEG confluyen una serie de características que deben ser consideradas, ya que en conjunto confieren riesgos para la salud. Los nacidos PEG en nuestro medio no presentan un patrón de crecimiento recuperador rápido y su menor tamaño persiste a los 6 meses de vida(AU)

Introduction: Being born small for gestational age (SGA) has short and long term risks. The aim of this study was to describe perinatal and socio-cultural characteristics, and the pattern of growth and diet of SGA infants during their first 6 months of life. Materials and methods: Anthropometry and diet were evaluated during six months in a representative sample of 1596 newborns the population of Aragon (Spain). Results: Mothers of SGA (N=94) infants gained less weight during pregnancy (10.5±5.8 vs 12.0±5.07kg, P=.012), gestational age at birth was lower (37.84±1.7 vs 39.06±1.6 weeks, P<.001), and the probability of cesarean delivery was higher (37.2% vs 20.5%, P=.001). The height of the mother was lower in the SGA group (1.61±0.58 vs 1.63±0.06 metres, P=.004), but their body mass index was similar. No differences were found between groups in social or cultural aspects. Mothers of SGA infants smoked more during pregnancy (32.3% vs 18.5%, P=.003) (RR = 1.92; 95% CI; 1.31 to 3.02). Infants born SGA remained smaller during the first 6 months of life, and the monthly weight gain was similar to the rest. In the SGA group, the prevalence of breastfeeding was lower at 4 months of age (54.9% vs 68.2%, RR = 0.58, 95% CI; 0.38 to 0.89). Conclusions: Infants born SGA are more likely to converge a number of characteristics that must be considered together because they may lead to health risks. SGA do not show a rapid recovery pattern of postnatal growth, and their smaller size persists at six months(AU)

Validación de una herramienta de cribado nutricional para pacientes pediátricos hospitalizados / Validation of a nutritional screening tool for hospitalized pediatric patients

Introducción: La malnutrición en los pacientes hospitalizados tiene implicaciones clínicas y evolutivas, por lo que existe interés en desarrollar métodos de cribado que identifiquen los individuos de riesgo. En la actualidad no existe consenso acerca de la herramienta de cribado nutricional más apropiada para aplicar en población pediátrica. Objetivo: Validar en España la herramienta de cribado nutricional pediátrico STAMP (Screening Tool for the Assessment of Malnutrition in Pediatrics). Métodos: Estudio descriptivo transversal en pacientes ingresados en un hospital pediátrico de tercer nivel con diferentes especialidades médicas y quirúrgicas. En las primeras 24 horas de ingreso se aplicó el método de cribado nutricional STAMP. Para la validación de sus resultados se llevó a cabo una valoración del estado nutricional que incluyó datos clínicos, antropométricos y de composición corporal realizada por personal especializado en nutrición. Resultados: Fueron estudiados 250 niños. La valoración nutricional detectó 64 pacientes (25,6%) considerados de riesgo, de los cuales 40 (16%) estaban ya malnutridos. STAMP clasificó un 48,4% de la muestra como de riesgo nutricional elevado. Dicho método mostró una sensibilidad del 75% y una especificidad del 60,8% para identificar los pacientes considerados de riesgo en la valoración nutricional, y una sensibilidad del 90% y especificidad del 59,5% para detectar los malnutridos. Comentarios: La frecuencia de malnutrición fue algo inferior a la de otros países de nuestro entorno, aunque el método diagnóstico fue diferente. El método STAMP es una herramienta sencilla y útil para el cribado nutricional, que evitaría la necesidad de valorar a todos los pacientes al ingreso para detectar los sujetos de riesgo (AU)

Background: Malnutrition among hospitalized patients has clinical implications, and interest has arisen to find screening tools able to identify subjects under risk. At present, there is no consensus about the most suitable nutrition screening tool for pediatric patients. Aim: To validate STAMP (Screening Tool for the Assessment of Malnutrition in Pediatrics) pediatric screening tool in Spain. Methods: Descriptive cross-sectional study of patients admitted to a 3rd level children's hospital with both medical and surgical specialities. During the first 24 hours of admission, STAMP screening tool was applied. For its validation, results were compared with those obtained from a nutritional assessment performed by specialist staff, which included clinical, anthropometric and body composition data. Results: A sample of 250 children was studied. Nutritional assessment identified 64 patients (25.6%) under risk, 40 of whom were malnourished (16%). STAMP classified 48.4% of the patients as being under nutritional risk. This tool showed 75% sensitivity and 60.8% specificity when identifying patients under risk according to nutritional assessment. It showed 90% sensitivity and 59.5% specificity when identifying malnourished patients. Comments: Malnutrition was less frequent than that reported in other European countries, although diagnosis technique was different. STAMP is a simple and useful tool for nutritional screening, avoiding the need to assess all patients on admission in order to identify those under nutritional risk (AU)

Severidad de caries y pérdida de dientes de una población pre-Hispánica del norte de Chile / Caries severity and tooth loss in an ancient pre-Columbian culture in the north of Chile

El conocer la historia natural de las patologías bucales sin intervenciones modernas, permite comparar el desarrollo de éstas con los datos actuales. Este estudio tiene como objetivo conocer la severidad de caries dental y de pérdida de dientes en una muestra de restos humanos de la cultura Atacameña (500 DC) en San Pedro de Atacama en el norte de Chile. Se estudiaron 139 restos humanos, en cada uno de ellos se realizó un examen clínico, consignado la información en una ficha individual donde se registró, el número de dientes presentes y perdidos pre y post mortem y el número de lesiones de caries. Estas variables permitieron calcular el índice CPD (Obturadas=0). El análisis estadístico incluyó una descripción de frecuencias y el cálculo de estadísticas de dispersión y tendencia central para las variables continuas. Los resultados muestran que el índice CPD mínimo, asume que las piezas perdidas post mortem estaban sanas fue 17.14 con un promedio de 3.93 lesiones de caries y 13.2 dientes perdidos en vida. Los restos humanos de la población estudiada presentan un gran daño de su salud bucal. Gran cantidad de piezas dentarias perdidas en vida y bajo número de dientes sanos.

The aim of this study was to determine the severity of dental caries and tooth loss in a sample of 139 human remains of the Atacama culture (500 AD) in San Pedro de Atacama, northern Chile. A clinical examination was performed on each remain by a calibrated examiner. The number of present and missing teeth in pre-and post-mortem stages and the number of carious lesions were recorded. The DMT index (filled = 0) was calculated. Statistical analysis included a description of frequency and calculation of statistical dispersion and central tendency for continuous variables. The results reveal a DMT of 17.14 with an average of 3.93 carious lesions and 13.2 teeth lost in life. The oral health situation of the studied population presented severe damage, high rate of tooth loss and DMT scores.

Prevalencia de caries en escolares de 6 a 15 años, Isla de Pascua / Caries prevalence in 6 to 15 year-old school children, from Easter Island

Objetivo: El objetivo de este estudio fue determinar la prevalencia y severidad de caries de piezas permanentes y algunos factores de riesgo relacionados en un grupo de escolares de Isla de Pascua. Materiales y Métodos: 116 niños de 6 a 15 años de edad fueron seleccionados al azar. Se efectuó examen clínico individualizado y se registraron los índices COP-D, significante de caries (SIC), de Higiene Oral de Greene y Vermillon (G-V) y se realizó una encuesta de dieta. Para conocer la frecuencia y recuento de Streptococcus mutans y Streptococcus sobrinus, se tomaron muestras de saliva estimulada a 23 niños Rapa Nui elegidos al azar. Finalmente, se analizaron muestras de agua potable en 3 sitios distintos de la isla para medir la cantidad de flúor disponible. Resultados: La prevalencia de caries en piezas permanentes fue 38 por ciento. El COP-D fue 1.19. El valor promedio del G-V fue 1.63. Se aisló e identificó S. mutans y S. sobrinus en el 56.2 por ciento y 13.2 por ciento respectivamente. El recuento promedio para S. mutans fue de 3.3x105 UFC/ml saliva y para S. sobrinus fue de 7.2x104 UFC/ml. Se observó un promedio de 0.223 ppm/Fluoruro en el agua. Desviación Estándar 0.025 ppm. Según la encuesta de dieta el 30 por ciento de los niños presenta bajo riesgo de caries, el 47 por ciento presenta mediano riesgo y el 23 por ciento presenta alto riesgo. Conclusión: El 38 por ciento presenta historia de caries en piezas permanentes. El COP-D promedio es 1.19. En niños Rapa Nui 0.9 y en No Rapa Nui 1.77.

Aim: The aim of this study was to determine the prevalence and severity of caries and some related risk factors in a group of school children from Easter Island. Materials and Methods: 116 children aged 6 to 15 years were randomly selected. Individual clinical examination was performed and index COP-D, significant caries index (SIC), Greene and Vermillon Oral Hygiene index (GV) were recorded. A diet survey was performed. To determine the frequency and count of Streptococcus mutans and Streptococcus sobrinus, stimulated saliva samples were collected from 23 Rapa Nui children randomly selected. Finally, samples of drinking water in 3 different places of the island were analyzed to measure the amount of fluoride available. Results: Caries prevalence was 38 percent. COP-D index was 1.19. The mean value of G-V was 1.63. S. mutans and S. sobrinus were isolated and identified in 56.2 percent and 13.2 percent of the samples, respectively. The average count for S. mutans was 3.3 x105 CFU/ml saliva and for S. sobrinus was 7.2 x104 CFU/ml. A mean of 0.223 Standard Deviation 0.025 ppm/Fluoride was observed in drinking water. According to the diet survey, 30 percent of children have a low risk of caries, 47 percent have medium risk and 23 percent a high risk. Conclusion: According to this study 38 percent have caries history in permanent teeth. Mean COP-D index was 1.19. In Rapa Nui children 0.9 and Not Rapa Nui children 1.77.

Histamine is required during neural stem cell proliferation to increase neuron differentiation.

Histamine in the adult central nervous system (CNS) acts as a neurotransmitter. This amine is one of the first neurotransmitters to appear during development reaching its maximum concentration simultaneously with neuron differentiation peak. This suggests that HA plays an important role in neurogenesis. We have previously shown that HA is able to increase neuronal differentiation of neural stem cells (NSCs) in vitro, by activating the histamine type 1 receptor. However the mechanism(s) by which HA has a neurogenic effect on NSCs has not been explored. Here we explore how HA is able to increase neuron phenotype. Cortex neuroepithelium progenitors were cultured and at passage two treatments with 100 µM HA were given during cell proliferation and differentiation or only during differentiation. Immunocytochemistry was performed on differentiated cultures to detect mature neurons. To explore the expression of certain important transcriptional factors involved on asymmetric cell division and commitment, RT-PCR and qRT-PCR were performed. Results indicate that HA is required during cell proliferation in order to increase neuron differentiation and suggest that this amine increases neuron commitment during the proliferative phase probably by rising prospero1 and neurogenin1 expression.

Características socioculturales, obstétricas y antropométricas de los recién nacidos hijos de madre fumadora / Socio-cultural, obstetric and anthropometric characteristics of newborn children of mothers who smoke in spain

Introducción: En España, una de cada tres mujeres fuma al inicio del embarazo; de ellas, un 25-50% dejan de fumar durante la gestación y la mayoría reinicia el consumo tras el parto. Entre los efectos del tabaquismo materno en el recién nacido, destaca el bajo peso al nacimiento con su consecuente morbilidad. El objetivo del estudio es comparar las características antropométricas y socioculturales de los hijos de gestante no fumadora con respecto a los de madre fumadora en nuestro medio. Materiales y métodos: Se han evaluado los hábitos de tabaquismo y las características socioculturales de una muestra de 1.499 embarazadas y las variables antropométricas de sus recién nacidos durante el año 2009 en Aragón. Resultados: Se observó en las 1.499 gestantes estudiadas una prevalencia de tabaquismo en la gestación de 19,6%; entre las españolas el 23% fumó durante la gestación frente al 11% de las extranjeras. Las madres fumadoras fueron más jóvenes y con un nivel educativo menor que las no fumadoras; sin embargo no se hallaron diferencias en sus características antropométricas. Los nacidos en Aragón hijos de madre fumadora tuvieron un menor peso al nacer respecto a los de no fumadoras (3.155 g vs 3.295 g: p < 0,001) y un riesgo relativo de nacer con bajo peso para su edad gestacional de 2,1 (IC 95%: 1,35-2,97). La longitud y resto de variables antropométricas del recién nacido también se vieron afectadas. Conclusiones: La prevalencia de tabaquismo durante la gestación en Aragón es alta. Las madres que fuman son más jóvenes y con características socioculturales diferentes a las no fumadoras. El hábito tabáquico materno repercute negativamente en el estado nutricional del recién nacido, suponiendo un riesgo evitable de bajo peso al nacer (AU)

Introduction: One in every four women smoke at the beginning of the pregnancy in Spain; of these, 25-50% give up smoking during gestation and most of them smoke again after child birth. Maternal smoking has harmful effects on babies, such as low birth-weight with its resulting morbidity. The objective of this study is to compare the anthropometric and socio-cultural characteristics between newborns from smoking mothers and those from non- smoking ones. Materials and methods: Smoking habits and the socio-cultural characteristics were assessed from a sample of 1499 pregnant women, as well as their newborn anthropometric variables of their newborn babies during 2009 in the Aragon region of Spain. Results: In the sample of 1499 pregnant women the prevalence of smoking during pregnancy was 19.6%; among the Spanish women, 23% of them smoked during the gestation compared with only 11% in women from other countries. The smoker mothers were younger and they had a lower educational level than the non smoker ones; however, there were no statistical differences between their anthropometric characteristics. Newborns from smoker women in Aragon had a lower weigh at delivery (3155 vs. 3295 grams: p < .001) and a relative risk of low weight at birth for their gestational age of 2.1 (95% CI: 1.35 --- 2.97). The length and the rest of newborn anthropometric variables were also affected. Conclusion: The prevalence of smoking during gestation is high in Aragon. The mothers who smoke are younger and have different socio-cultural characteristics compared with non-smoker mothers. Maternal smoking habits have a harmful effect on newborn nutritional status, representing an avoidable risk of low weight at birth (AU)

[Validation of a nutritional screening tool for hospitalized pediatric patients]. / Validación de una herramienta de cribado nutricional para pacientes pediátricos hospitalizados.

BACKGROUND: Malnutrition among hospitalized patients has clinical implications, and interest has arisen to find screening tools able to identify subjects under risk. At present, there is no consensus about the most suitable nutrition screening tool for pediatric patients. AIM: To validate STAMP (Screening Tool for the Assessment of Malnutrition in Pediatrics) pediatric screening tool in Spain. METHODS: Descriptive cross-sectional study of patients admitted to a 3rd level children's hospital with both medical and surgical specialities. During the first 24 hours of admission, STAMP screening tool was applied. For its validation, results were compared with those obtained from a nutritional assessment performed by specialist staff, which included clinical, anthropometric and body composition data. RESULTS: A sample of 250 children was studied. Nutritional assessment identified 64 patients (25.6%) under risk, 40 of whom were malnourished (16%). STAMP classified 48.4% of the patients as being under nutritional risk. This tool showed 75% sensitivity and 60.8% specificity when identifying patients under risk according to nutritional assessment. It showed 90% sensitivity and 59.5% specificity when identifying malnourished patients. COMMENTS: Malnutrition was less frequent than that reported in other European countries, although diagnosis technique was different. STAMP is a simple and useful tool for nutritional screening, avoiding the need to assess all patients on admission in order to identify those under nutritional risk.

Soporte nutricional en la enfermedad renal crónica / Nutritional support in chronic kidney disease

Los niños con una enfermedad renal crónica tienen un alto riesgo de desnutrición y requieren un soporte nutricional especializado, sobre todo en un estadio de la enfermedad mayor o igual a 2. La pérdida de función de un órgano metabólicamente tan activo entraña alteraciones en el metabolismo intermediario de los nutrientes, así como en la biodisponibilidad y la pérdida de éstos. El riñón enfermo tiene una pérdida de función progresiva en la que están implicados muchos factores, entre los que el factor nutricional es importante. El retraso de crecimiento es la afectación más importante durante la infancia. La alteración depende del grado de afectación y de la edad del paciente. El riesgo es mayor cuando la enfermedad es congénita, porque durante el primer año la velocidad de crecimiento es muy alta y los requerimientos nutricionales muy elevados y de difícil cobertura. Las alteraciones motoras del tracto gastrointestinal producen anorexia y vómitos que dificultan la ingesta; por ello, estos pacientes frecuentemente requieren suplementación nutricional y una nutrición enteral prolongada mediante gastrostomía, que en general es endoscópica percutánea (AU)

Children with chronic kidney disease are vulnerable to malnutrition, needing specific nutritional support to prevent it, especially when the disease is in a phase greater than 2 the loss of the function of such an active organ metabolically causes alteration in the intermediary metabolism of the nutrients, as well as in the nutrient bioavailability and losses. Several factors are involved in the progressive loss of renal function, and nutritional factors are very important. Growth retardation is the most important affectation during childhood; the alteration depends in the degree of affectation and the patient’s age. The risk is greater when the disease is congenital because during the first year the speed of the growth is very high and the nutritional requirements are very high and of very difficult coverage. The changes in motor skills of the gastrointestinal tract cause anorexia and vomits that cause difficulty in the consumption, due to this reason they frequently need nutritional supplementation and prolonged enteral nutrition through gastrostomy, which is generally percutaneous endoscopic (AU)
