ABSTRACT

Objetivos: Analizar las características cronobiológicas y las variaciones temporales del paro cardiaco extrahospitalario (PCEH). Diseño: Estudio descriptivo retrospectivo. Pacientes: Todos los casos de PCEH de origen cardíaco registrados en la base de datos del servicio de emergencias médicas (SEM) de la Comunidad Autónoma de Castilla y León (España) durante 18 meses. Variables de interés principales: Edad, sexo, recuperación de la circulación espontánea, primer ritmo monitorizado (desfibrilable /no desfibrilable), lugar de alerta [(hogar, lugar público, centro atención primaria (AP)], testigo (familiar, transeúnte, fuerzas de seguridad, personal AP), hora de alerta (0-8; 8-16; 16-24), hora de activación del equipo de emergencias, hora de atención y día de la semana. Análisis univariante mediante Chi2, varianza y tests no paramétricos. Análisis cronobiológico mediante transformada rápida de Fourier y test Cosinor. Resultados: Se estudiaron 1.286 casos registrados entre enero 2007 y junio 2008. Se observaron diferencias estadísticas significativas en menor edad (p<0,05), mayor incidencia en el hogar (p<0,001) y mayor frecuencia de familiares-convivientes como testigos (p<0,001) en el periodo de 0-8h. El análisis cronobiológico mostró ritmo diario (circadiano) con acrofase a las 11:16h (p<0,001) y ritmo semanal (circaseptano) con acrofase en miércoles (p<0,05). Las medianas de intervalos alerta-atención y activación-atención fueron respectivamente 11,7min y 8,0min, sin diferencias entre periodos horarios. Conclusiones: Se demuestra la presencia de un ritmo diario de aparición del PCEH con pico matinal y un ritmo semanal con pico en miércoles. Estos resultados orientan al ajuste preventivo y a la planificación de recursos y mejoras en la respuesta, en determinados periodos horarios (AU)


Objectives: To analyze the chronobiological and time variations of out- hospital cardiac arrest (OHCA). Design: A retrospective descriptive study was made. Patients: All cases of OHCA of cardiac origin registered over 18 months in the database of the emergency medical service (EMS) of the Autonomous Community of Castilla y León (Spain) were evaluated. Variables analyzed: Age, sex, recovery of spontaneous circulation (ROSC), first monitored rhythm (amenable / not amenable to defibrillation), alert site [(home, public place, primary care (PC) center], alerting person (family, witness, law enforcement member, PC center staff), alert time (0-8; 8-16; 16-24), emergency team activation time, care time and day of the week. Univariate analysis (chi-squared), variance, and nonparametric tests comparing the variables in three periods of 8hours. Chronobiological analysis by fast Fourier transform and Cosinor testing. Results: We studied 1286 cases reported between January 2007 and June 2008. Statistically significant differences were observed in terms of younger age, higher incidence in the victim's home, and greater frequency of family-cohabiting persons as witnesses in the period between 0 and 8hours. Chronobiological analysis found daily rhythm (circadian) with acrophase at 11.16h (p<0.001) and weekly rhythm (circaseptan) with acrophase on Wednesday (p<0.05). The median alert time-care time interval and emergency team activation time-care time were 11.7min and 8.0min, respectively, without differences between periods. Conclusions: We have demonstrated the presence of a daily rhythm of emergence of OHCA with a morning peak and a weekly rhythm with a peak on Wednesdays. These results can guide the planning of resources and improvements in response in certain time periods (AU)

ABSTRACT

Attention-deficit/hyperactivity disorder (ADHD) is the most common neurobehavioral disorder in children and adolescents; however, its etiology is still unknown, which hinders the existence of reliable, fast and inexpensive standard diagnostic methods. In this paper, we propose a novel methodology for automatic diagnosis of the combined type of ADHD based on nonlinear signal processing of 24h-long actigraphic registries. Since it relies on actigraphy measurements, it constitutes an inexpensive and non-invasive objective diagnostic method. Our results on real data reach 96.77% sensitivity and 84.38% specificity by means of multidimensional classifiers driven by combined features from different time intervals. Our analysis also reveals that, if features from a single time interval are used, the whole 24-h interval is the only one that yields classification figures with practical diagnostic capabilities. Overall, our figures overcome those obtained by actigraphy-based methods reported and are comparable with others based on more expensive (and not so convenient) adquisition methods.

ABSTRACT

Objetivo: Analizar las características generales de la parada cardiaca extrahospitalaria(PCEH) en una comunidad autónoma y los factores asociados a la recuperación de la circulación espontánea (RCE).Método: Estudio descriptivo retrospectivo de las PCEH de origen cardiaco incluidas en la base de datos del servicio de emergencias (SEM) de Castilla y León en un periodo de18 meses. El objetivo primario fue la RCE. Las variables analizadas fueron la edad, sexo, ritmo desfibrilable (DF), lugar del paro, testigo, intervalo alerta-atención inicial e intervalo despacho SEM-atención inicial. Resultados: Se estudiaron 1.286 PCEH, que representan 0,34 casos/1.000 habitantes/año. La mediana de edad fue de 73,0 años (rango intercuartílico 21,0), y el66,5% fueron hombres. Se consiguió RCE en el 22,2%. Las características de la PCEH fueron: ritmo DF 15,3%; en el hogar 72,2%, en un lugar público 21,3%, en un centro atención primaria (AP) 6,5%; presenciada por un familiar 49,1%, por un transeúnte 31,6%, por fuerzas seguridad 2,6% y por personal AP 15,7%. Fueron variables independientes asociadas a la RCE: edad inferior a 50 años [OR 1,6 (IC 95%: 1,03; 2,4)],ritmo DF [OR 3,8 (IC 95%: 2,7; 5,3)], lugar del paro en centro AP [OR 2,7 (IC 95%:1,4; 4,9)] y en lugar público [OR 1,8 (IC 95%: 1,2; 2,7)].Conclusiones: La incidencia de PCEH fue similar a otras series europeas. Destaca el bajo porcentaje de ritmos DF. Se confirma el hogar como lugar de más frecuente presentación, y una menor edad, la presencia de ritmos DF y la presentación en lugares públicos o centros sanitarios, como factores independientes asociados a RCE (AU)


Objective: To analyze the general characteristics out of hospital cardiac arrest (OHCA) including the frecuency of return of spontaneous circulation and related factors. Methods: Retrospective descriptive analysis of cases of OHCA in the records of the emergency medical service of Castile-Leon covering a period of 18 months. The main independent outcome analyzed was return of spontaneous circulation. Independent variables analyzed were age, sex, presence of shockable rhythm, location of cardiac arrest, witness, time between emergency call and initiation of care, and time between ambulance dispatch and initiation of care. Results: The EMS attended a total of 1286 cases of OHCA, representing an annual incidence of 0.34 cases per 1000 population. The median age (interquartile range) was 73.0 (21.0) years; 66.5% of the patients were men, spontaneous circulation returned in 22.2%, and a shockable rhythm was present in 15.3%. Cardiac arrest occurred in the home in72.2% of the cases, in a public place in 21.3%, and at a primary health care clinic in 6.5%. Witnesses were a familymember (49.1%), a passer-by (31.6%), a member of a security force (2.6%), and a primary care staff member (15.7%).Independent variables related to return of spontaneous circulation were age under 50 years (odds ratio [OR], 1.6; 95% confidence interval [CI], 1.03-2.4), presence of a shockable rhythm (OR, 3.8; 95% CI, 2.7-5.3); cardiac arrest at a primary health care clinic (OR, 2.7; 95% CI, 1.4-4.9) or in a public place (OR, 1.8; 95% CI, 1.2-2.7).Conclusions: The incidence of OHCA was similar to that reported for other European series. The low percentage of shockable rhythm was noteworthy. The home was confirmed as the most common setting for cardiac arrest; lower age, presence of shockable rhythm, occurrence of cardiac arrest in a public place or at a primary care clinic were confirmed as variables independently associated with return of spontaneous circulation (AU)

ABSTRACT

Objetivo. Valoración de la relación entre las fracturas de la extremidad superior y la dimensión temporal.Material y método. Se estudiaron 16.736 pacientes ingresados en hospitales del sistema público de salud de Castilla y León con fracturas de la extremidad superior, de 1999 a 2004. Se realizó un análisis univariante y una regresión logística, estudio ritmométrico con análisis espectral (transformada de Fourier) y método cosinor, para indagar la existencia de ritmo.Resultados. La edad media de los enfermos fue de 45,1 ±25,7 años, con un 57,9% de varones. La fractura se produjo en el ámbito urbano en un 62,8% y por accidente de tráfico en un 21,7%. Fue tratado con cirugía el 63,1%, con una mortalidad del 1,6%. La estancia media fue de 7,21 días. La regresión logística mostró menor riesgo para mujeres, ámbito urbano y aumento de la edad. Análisis espectral: período dominante de 365 días. Análisis de cosinor: ritmo significativo (acrofase: 13/8 y batifase: 31/12). Todos los subgrupos, excepto exitus y mayores de 84 años, mostraron ritmo (acrofasesde 19/7 a 8/9).Conclusiones. Este grupo de fracturas y la mayoría de subgrupos muestran ritmo con acrofases en verano. Tráfico y no tráfico tienen ritmos semejantes. Los datos del estudio cronobiológico se pueden aplicar en la clínica, mediante la planificación de los recursos con sentido temporal


Purpose. To assess the relationship between fractures of the upper limb and the time dimension.Materials and methods. A study was conducted of 16,736patients admitted to Castile-Leon hospitals with a fracture of their upper limb between 1999 and 2004. The following analyses were performed to investigate the existence of rhythm: an univariate analysis performed together with a logistic regression, a rhythmometric study with spectral analysis (Fourier transform) and cosinor method.Results. Patients’ mean age was 45.1 ± 25.7 years, with57.9% of males. The fracture was sustained in an urban milieu in 62.8% of cases and as a result of a road accident in 21.7%. Surgery was performed in 63.1% of cases, with a mortality rate of 1.6%. Mean hospitalization time was 7.21 days. Logistic regression showed a lower risk for older females, in the urban setting. Spectral analysis: dominant periodof 365 days. Cosinor analysis: significant rhythm(acrophase: 13/8 and batiphase: 31/12). All subgroups except for deceased patients and those over 84 years showed rhythm (acrophases: 19/7 to 8/9).Conclusions. This group of fractures, as well as the majority of subgroups, shows rhythm with acrophases in the summer. Traffic and non-traffic have similar rhythms. The data from the chronobiological study can be applied to clinical practice by planning resources with time-based criteria (AU)

ABSTRACT

Introducción: El estudio tiene como objetivo analizar la variabilidad de presentación de las gastroenteritis agudas en nuestro medio. Pacientes y métodos: La población de estudio estuvo constituida por 2.309 pacientes menores de 24 meses de edad, ingresados con diagnóstico de gastroenteritis. Se realizó un cultivo de heces en todos los casos y fueron clasificados, según la etiología, mediante la CIE-9-MC, como infecciosas, víricas, bacterianas y no infecciosas. Se tuvieron en cuenta las siguientes variables: sexo (hombre/mujer), edad (meses), días de estancia, fecha de ingreso y fallecimiento. Se llevó a cabo un análisis descriptivo y, además, el test de Kolmogorov-Smirnov, la prueba de la t de Student y de la ji al cuadrado con prueba exacta de Fisher. El análisis ritmométrico se llevó a cabo mediante la transformada rápida de Fourier, con ajuste de modelos mediante método cosinor con varios armónicos. Resultados: Ingresaron por gastroenteritis el 18,9% de los pacientes; eran de tipo infecciosa el 35% y vírica el 25,5%.La edad media de presentación de las gastroenteritis víricas fue de 10,84 meses, mientras que en las no víricas fue de11,74 meses, con un día más de estancia hospitalaria en el primer grupo. El análisis cosinor muestra un componente rítmico con un periodo de 12 meses en el global de las gastroenteritis, subgrupo de víricas y no víricas, con acrofase a finales de marzo. Conclusiones: Las gastroenteritis presentan un patrón estacional, con ritmo circanual y periodo de 12 meses, más patente en las gastroenteritis víricas que en las no víricas(AU)


Background: The aim of this study was to analyze the variability of epidemiological and clinical findings in gastroenteritis in our setting. Methods: We studied 2,309 patients, aged between 0 and24 months, admitted with a diagnosis of acute gastroenteritis. Stools were cultured and examined for a variety of enteropathogens, which were classified as infectious, viral, bacterial and noninfectious (CIE-9-MC). We considered the following variables: sex (male/female), age (months), hospital stay (days),date of admission and mortality. A descriptive analysis was carried out, and the Kolmogorov-Smirnov test, Student’s t test and the chi-square test with Fisher’s exact test were applied. Rhythmicity was analyzed using fast Fourier transform, and variations in rhythm were assessed by the cosinor model, with different harmonics. Results: Overall, 18.9% of the hospital admissions were dueto gastroenteritis (35% of infectious etiology and 25.5% of viral etiology). The mean age of infants with viral gastroenteritis was10.84 months, whereas in cases produced by non viral pathogens, it was 11.74 months. Patients with viral gastroenteritis were hospitalized one day longer than those with gastroenteritis due to non viral agents. The cosinor analysis revealed the presence of a rhythmic component, with 12-month duration in overall cases of gastroenteritis, and in viral and non viral gastroenteritis. The acrophase was around the 12th week of the year. Conclusions: Gastroenteritis exhibits a seasonal pattern, with a 12-month circannual rhythm, which is more evident in viral gastroenteritis than in cases produced by non viral pathogens (AU)

ABSTRACT

Objetivo. Estudiar la presencia y características del ritmo circadiano en la hora de inicio de los síntomas del infarto de miocardio (IAM) en un grupo de población geriátrica española.Ámbito. Unidades Coronarias adscritas al proyecto ARIAM. Diseño. Estudio de cohorte retrospectivo. Pacientes registrados en el proyecto multicéntrico ARIAM. Se seleccionaron los pacientes con diagnóstico de IAM al alta de la Unidad Coronaria (54.249 pacientes), registrados entre mayo de 1994 y octubre de 2003. Intervención. Ninguna. Variables de interés principales. Se analiza la hora de inicio del IAM, características generales de la población y del IAM (sexo, edad, extensión y localización del IAM y mortalidad dentro de la Unidad Coronaria). Se estratifica la población por edad (menores de 65 años, 65-74 años, 75-84 años y mayores de 85 años) y se comparan entre sí los subgrupos resultantes. Se aplica la prueba del χ2 sobre el porcentaje de pacientes agrupados en períodos de 6 horas. Resultados. La hora de inicio del dolor en el IAM muestra ritmo circadiano en todos los subgrupos de edad (p < 0,001). La frecuencia máxima se localiza en el período horario entre las 6 y 12 de la mañana; mientras que la frecuencia mínima se observa entre las 0 y 6 de la mañana, salvo en la población mayor de 85 años, en la que la frecuencia mínima se localiza entre las 6 de la tarde y la medianoche. La comparación entre los distintos subgrupos de edad muestra diferencias estadísticamente significativas, salvo en la comparación entre los subgrupos de 75-84 años y 85-100 años (p = 0,13). Conclusiones. El IAM en la población geriátrica, al igual que en la no geriátrica, muestra ritmo circadiano en la hora de presentación de sus síntomas. El pico de máxima incidencia matinal se acentúa con la edad. La incidencia mínima es nocturna, salvo en los muy ancianos, que es vespertina


Objective. Study the presence and characteristics of circadian rhythm when myocardial infarction (AMI) symptoms initiate in a group of Spanish geriatric population. Scope. Coronary Units included in ARIAM project. Design. Retrospective cohort study. Patients registered in the multicenter project ARIAM. Patients diagnosed of AMI on discharge from the Coronary Unit (54,249 patients), registered between May 1994 and October 2003, were selected. Intervention. None. Variables of principal interest. Time of onset of AMI, general characteristics of the population and AMI (gender, age, extension and location of AMI and mortality within the coronary unit) were analyzed. The population was stratified by age (younger than 65 years, 65-74 years, 75-84 years and older than 85 years) and the resulting subgroups were compared. The χ2 test was applied on the percentage of patients grouped in 6 hour periods. Results. Time of onset of pain in AMI showed circadian rhythm in all the age subgroups (p < 0.001). Maximum frequency was located in the time period between 6 a.m. and 12 p.m., while minimum frequency was observed between 12 a.m and 6 a.m., except in the population over 85 years, in which the minimum frequency was located between 6 p.m. and midnight a.m. Comparison between the different age subgroups showed statistically significant differences, except in the comparison between the subgroups of 75-84 years and 85-100 years (p = 0.13). Conclusions. Those with AMI in the geriatric population, as in the non-geriatric one, show circadian rhythm when their symptoms occur. Peak of maximum morning incidence increase with age. Minimum incidence is at night, except in the very elderly, where it is in the evening

ABSTRACT

BACKGROUND: Ostium secundum-type atrial septal defect (ASD) is usually well tolerated, without severe complications in childhood. However, in many patients its effect on growth is disproproportionate when compared with that of more serious congenital heart disease. OBJECTIVES: To test the hypothesis that hemodynamic disturbances are responsible for failure to thrive in congenital heart disease, we studied growth and the effect of surgical repair in children with ASD. PATIENTS AND METHODS: The study was performed in 72 patients who underwent surgery at a mean age of 8 years and 8 months. The mean follow-up was 17 months. Somatometric and hemodynamic parameters were studied and the correlation between them was verified. The effect of surgery and of age at operation on somatometric changes was evaluated. RESULTS: Fifty-two percent of the patients were malnourished and height was affected in 28 %. The correlation between weight and age at operation was r 5 0.78 (p < 0.05) for the entire group, r 5 0.81 (p < 0.05) for the malnourished subgroup and r 5 0.88 (p < 0.05) for the subgroup with normal nutrition. No relationship was found between hemodynamic and somatometric parameters. Surgery improved growth disturbances but not in all patients (weight: from 52 % to 32 %; height: from 28 % to 16 %). CONCLUSIONS: Hemodynamic factors are not the only cause of growth and nutritional alterations.

ABSTRACT

Antecedentes La comunicación interauricular (CIA) ostium secundum suele ser bien tolerada, sin complicaciones notables en la edad pediátrica. Sin embargo, muchos casos presentan repercusión desproporcionada sobre el crecimiento, en comparación con las cardiopatías más graves. Objetivos: Con la hipótesis de que el factor hemodinámico es responsable de la malnutrición en las cardiopatías congénitas, se establece el objetivo de conocer el crecimiento en la CIA y el efecto de la cirugía correctora, con el fin de valorar la implicación hemodinámica. Pacientes y métodos: El estudio se llevó a cabo sobre 72 casos, operados a una edad promedio de 8 años y 8 meses, con un seguimiento medio de 17 meses. Se cuantificaron parámetros somatométricos y hemodinámicos, se verificaron las relaciones entre ellos, y se valoró el efecto de la cirugía y de la edad operatoria sobre los cambios somatométricos. Resultados: Se encontró malnutrición ponderal en el 52 por ciento, con repercusión equivalente en talla en el 28 por ciento. La correlación entre peso y edad operatoria para el total de la serie fue r 0,78, p < 0,05; para el subgrupo de malnutridos r 0,81, p < 0,05; y para los casos con nutrición normal r 0,88, p < 0,05.No se encontró relación entre los parámetros hemodinámicos y somatométricos. La cirugía produce mejoría, pero la alteración del crecimiento no mejora en la totalidad de los casos (peso: de 52 a 32 por ciento; talla de 28 a 16 por ciento).Conclusiones El factor hemodinámico no es el único responsable de la perturbación del crecimiento y la nutrición (AU)

ABSTRACT

Cada vez es mayor el interés por el análisis de la variabilidad de variables fisiológicas, en aplicaciones diagnósticas y pronósticas. Una condición esencial para este proceso, es la disponibilidad de series de datos en el tiempo. En este trabajo presentamos el desarrollo y aplicación de un sistema automático de transferencia de datos. El equipo se basa en un polígrafo para registro de 8 variables, con registrador térmico de 5 canales. Ordenador personal con un programa de diseño específico que permite captar del polígrafo los datos de las variables, a intervalos tan cortos como de 1 minuto. Las observaciones se depositan en una base de datos para análisis posterior del tipo de ritmo biológico que presentan. El sistema se completa con registro contínuo de actividad en videocámara, a razón de 3 imágenes/seg. Se comenta el rendimiento del sistema. (AU)

ABSTRACT

Antecedentes: Se cree que algunos grupos étnicos enferman menos, sin que exista en nuestro medio objetivación científica, lo que justifica su estudio. Objetivo: Analizar la frecuencia de ingreso hospitalario y el tipo de enfermedad de lactantes según su etnia. Material y métodos: En el año 2000 se registraron 496 ingresos de niños entre 1 y 24 meses de edad. La variable grupo étnico clasificó 403 casos como etnia no gitana (81,25%) y 93 como etnia gitana (18,75%). A partir de la demografía de referencia se observaron las variables etnia y grupo de diagnóstico principal. Se utilizó análisis estadístico descriptivo de las diferentes variables, considerando diferencias significativas cuando p < 0,05. Resultados: El grupo etnia gitana representa el 6,51% de la población lactante, mientras que acapara el 18,75% de los ingresos hospitalarios (p < 0,05). El grupo étnico gitano registró 54,8% de reingresos frente al 20,80% del no gitano (p < 0,001). El grupo étnico gitano presentó mayor prevalencia de procesos respiratorios (35,48%) que el grupo etnia no gitana (22,58%) (p < 0,05). Sin embargo, fue mayor la proporción de patología digestiva en la etnia no gitana, 34,73% frente a 19,35% (p < 0,05). Los restantes grupos diagnósticos no presentaron diferencias significativas. Conclusión: La diferencia registrada entre la distribución demográfica y frecuencia de ingreso va en contra de la creencia de la mayor resistencia a enfermar del grupo étnico gitano. Las diferencias pueden deberse a las condiciones socioeconómicas, higiénicas, sanitarias y educacionales entre ambos grupos. Hecho significativo en los procesos de tipo respiratorio, probablemente por mayor hacinamiento. El estilo de vida de nuestra población asistida de etnia, no confiere mayor resistencia a la enfermedad (AU)

ABSTRACT

BACKGROUND: Some ethnic groups are thought to have greater resistance to disease. However, scientific studies of this phenomenon are lacking in our environment. OBJECTIVE: To study hospitalization rates and type of disease among infants according to ethnic group. MATERIAL AND METHODS: In 2000, 496 infants aged between 1 and 24 months were admitted to our hospital. Using ethnic group as a variable, 403 infants (81.25 %) were classified as non-gypsy and 93 (18.75 %) as gypsy. Demographic data were used to compare the variables of ethnicity and the main diagnostic group. Descriptive statistical analysis of the variables was performed. Differences were considered significant when p < 0.05. RESULTS: The gypsy group represented 6.51 % of the infant population but accounted for 18.75 % of infant admissions (p < 0.05). The gypsy group accounted for 54.83 % of readmissions compared with 20.80 % in the non-gypsy group (p < 0.001). Respiratory disease was more prevalent in the gypsy group (35.48 %) than in the non-gypsy group (22.58 %) (p < 0.05). However, digestive problems were more frequent in the non-gypsy group (34.73 %) than in the gypsy group (19.35 %) (p < 0.05). No statistically significant differences were found in other diagnostic groups. CONCLUSION: The differences observed between demographic distribution and admission rate contradict the belief that members of the gypsy ethnic group show greater disease resistance. The differences in admission rate and diagnostic group may be due to socioeconomic, hygienic, health and educational differences between both groups. Differences in the prevalence of respiratory disease were probably due to overcrowding. Gypsy lifestyle in our population does not confer greater disease resistance.

ABSTRACT

El cólico infantil modifica el comportamiento del niño y su relación con la dinámica familiar. Se establecen las hipótesis de que el cólico infantil está influido por la ingesta de proteína vacuna; que el cólico infantil no altera el ritmo biológico sueño/vigilia; y que no existen diferencias con el empleo de dos fórmulas de hidrolizado diferentes. Se toman como objetivos: 1) conocer la repercusión del cólico sobre el comportamiento del lactante; 2) cuantificar la repercusión del cólico sobre los parámetros actigráficos del sueño y el ritmo sueño/vigilia; 3) estudiar la influencia del cambio dietético sobre las variables enunciadas. El diseño elaborado a través de un estudio de intervención, prospectivo, longitudinal, concurrente y aleatorizado por bloques, con dos cohortes; se lleva a cabo con una población de 20 casos de niños con cólico que toman proteína de vaca y pasan a tomar dos tipos de fórmula modificada y 20 controles con cólicos que siguen con proteína de vaca. La sustitución de proteína de vaca por fórmulas con hidrolizados de proteína sérica y de soja, mejora las variables cualitativas que caracterizan a los casos con cólico, y mejora las variables cuantitativas al menos en un tercio de su cuantía. El hidrolizado de proteína sérica produce mejoría significativa; no así el hidrolizado de soja.La exclusión de proteína vacuna en la dieta, no produce cambios en los parámetros de sueño registrados por actimetría; y no modifica los parámetros del ritmo circadiano sueño/vigilia en los casos. La supresión de proteína en la madre lactante y la sustitución de fórmula por hidrolizado de proteínas, es un método aceptable, que produce mejoría en un tercio de los niños con cólico intestinal (AU)

ABSTRACT

OBJECTIVE: The toxicity of bilirubin (BP) on the brain presents unknown aspects. Therefore, the treatment for neonatal hyperbilirubinemia is controversial. The aim of this study was to establish if moderate levels of BP produce toxicity in brain nuclei that regulate the biological rhythms (BR) of healthy full-term newborns. PATIENTS AND METHODS: We studied 17 jaundiced (BP 12.8-18.1 mg/dl) and 36 non jaundiced newborns. Heart and respiratory rate, temperature and systolic blood pressure were recorded during 24 hours at 30 minute intervals. Cosinor analysis was used to calculate the incidence of BR. The Fisher exact test was carried out to compare both groups and the relative risks to determine the association between hyperbilirubinemia and the absence of BR. RESULTS: Differences in the BR parameters did not reach statistical significance. Differences in heart rate 12-h BR (p = 0.071) and systolic blood pressure 8-h BR (p = 0.076) approached a statistical significance. The 95% confidence intervals of the relative risks were all close to 1 and the lower limits in respiratory rate (0.40) and systolic blood pressure (0.35) 24-h BR indicate a negative association. CONCLUSIONS: The aim was to verify the relationship between moderate neonatal hyperbilirubinemia and the decrease in the incidence of BR. The results do not show the sought after relationship and provide evidence against neurotoxicity from moderate levels of bilirubin. The limited evidence for developing long term mental alterations permits us to make an optimistic prognosis for full-term newborns with moderately elevated levels of bilirubin.

ABSTRACT

The present investigation analyzes the relationship between one of the principal behavioral factors associated with cardiovascular disease in the adult (the type A behavior pattern) and resting physiological measures (blood pressure and heart rate) in an adolescent sample. Two other psychosocial factors, anger and anxiety, were also analyzed. The study was carried out on 410 adolescents. The results showed that most adolescents who had high resting blood pressure were type-A personalities, showing scores significantly higher in the impatient and hostile components. Results also showed that these subjects scored quite high on anxiety and anger scales when compared to the control group.

ABSTRACT

This study was designed to address the following objectives: 1) To record the respiratory rate in a population of newborns and infants. 2) To verify the existence of a rhythm in each population group, as well as the organization and maturing process of these rhythms. 3) To determine the possible influence of environmental factors on these rhythms. The study population consisted of the following groups and ages: A) 1 day (21 cases); B) 7 (15 cases); C) 15 (10 cases); D) 30 (17 cases); E) 60 (17 cases); F) 90 (18 cases). Respiratory rate was continuously monitored and recorded, as well as environmental light, noise and temperature. Rhythmometric analysis of the data was done by simple Cosinor test and analysis of variance. The zero amplitude test showed statistically significant differences in the circadian rhythm of groups E and F (p < 0.005). An ultradian rhythm of 3 hours was detected in groups D and F. Environmental factors also showed a circadian rhythm. The appearance of an ultradian rhythm suggest the maturation in a rhythm. To evaluate physiological parameters, reference to time series must be considered.
