Takotsubo syndrome associated with myasthenic crisis. A case report / Síndrome de takotsubo asociado a crisis miasténica. Presentación de un caso

Abstract: Introduction: The takotsubo syndrome is a rare clinical entity commonly associated with elderly women (ratio 6:1), easily confused with an acute ischemic syndrome, strangely associated with a myasthenic crisis. It is characterized with chest pain, elevated biomarkers, ST segment elevation, absence of coronary flow obstruction, and a characteristic deformity (anteroapical dyskinesia) of the left ventricle; these changes associated with a stressor. Case report: A woman of 69 years, diagnosed with myasthenia gravis six years ago, who entered in the intensive care unit with a suspected diagnosis of acute coronary syndrome and respiratory failure which required mechanical ventilation. Coronary angiography discarded a coronary disease. Ventriculography revealed a systolic anteroapical deformation. Treatment was initiated with acetylcholinesterase inhibitors and plasmapheresis with partial response, it required the use of vasoactive amines, with a suitable progressive cardiovascular and neurological outcome, with echocardiographic resolution. Conclusions: The takotsubo syndrome can be associated with myasthenia gravis and myasthenic crisis. The prognosis depends on early diagnosis, appropriate differential diagnosis, immediate treatment of myasthenic crisis, and management of the hemodynamic consequences of the takotsubo syndrome.

Resumen: Introducción: El síndrome de takotsubo es una entidad clínica poco frecuente asociada comúnmente con las mujeres de edad avanzada (relación 6:1), puede fácilmente confundirse con un síndrome isquémico agudo, extrañamente asociado con una crisis miasténica. Se caracteriza por dolor torácico, biomarcadores elevados, elevación del segmento ST, ausencia de obstrucción del flujo coronario, y una deformidad característica (discinesia anteroapical) del ventrículo izquierdo; estos cambios asociados con un factor de estrés. Caso clínico: Una mujer de 69 años, con diagnóstico de miastenia gravis hace seis años, que ingresó en la Unidad de Cuidados Intensivos con un diagnóstico de sospecha de síndrome coronario agudo e insuficiencia respiratoria que requirió de ventilación mecánica. La angiografía descartó una enfermedad coronaria. La ventriculografía reveló una deformación anteroapical sistólica. Se inició el tratamiento con inhibidores de la acetilcolinesterasa y plasmaféresis con respuesta parcial, se requirió el uso de aminas vasoactivas, con un resultado progresivo cardiovascular y neurológico adecuado, con resolución ecocardiográfica. Conclusiones: El síndrome de takotsubo puede estar asociada con miastenia gravis y la crisis miasténica. El pronóstico depende del diagnóstico precoz, el diagnóstico diferencial adecuado, el tratamiento inmediato de la crisis miasténica, y la gestión de las consecuencias hemodinámicas del síndrome takotsubo.

Reproducibility and validity of a food frequency questionnaire among pregnant women in a Mediterranean area.

BACKGROUND: Studies exploring the role of diet during pregnancy are still scarce, in part due to the complexity of measuring diet and to the lack of valid instruments. The aim of this study was to examine the reproducibility and validity (against biochemical biomarkers) of a semi-quantitative food frequency questionnaire (FFQ) in pregnant women. METHODS: Participants were 740 pregnant women from a population-based birth cohort study in Valencia (INMA Study). We compared nutrient and food intakes from FFQs estimated for two periods of pregnancy (reproducibility), and compared energy-adjusted intake of several carotenoids, folate, vitamin B12, vitamin C and α-tocopherol of the FFQ in the first trimester with their concentration in blood specimens (validity). RESULTS: Significant correlations for reproducibility were found for major food groups and nutrients but not for lycopene (r=0.06); the average correlation coefficients for daily intake were 0.51 for food groups and 0.61 for nutrients. For validity, statistically significant correlations were observed for vitamin C (0.18), α-carotene (0.32), ß-carotene (0.22), lutein-zeaxantin (0.29) and ß-cryptoxantin(0.26); non-significant correlations were observed for retinol, lycopene, α-tocopherol, vitamin B12 and folate (r≤0.12). When dietary supplement use was considered, correlations were substantially improved for folate (0.53) and to a lesser extent for vitamin B12 (0.12) and vitamin C (0.20). CONCLUSION: This study supports that the FFQ has a good reproducibility for nutrient and food intake, and can provide a valid estimate of several important nutrients during pregnancy.

Dietary intake in pregnant women in a Spanish Mediterranean area: as good as it is supposed to be?

OBJECTIVE: To assess food and nutrient intakes and compliance with nutritional recommendations in pregnant women according to selected sociodemographic characteristics. DESIGN: Cross-sectional study based on data from the INMA-Valencia cohort (Spain), which recruited pregnant women between 2004 and 2005. Information on maternal sociodemographics and anthropometry was collected. Dietary intake was assessed through an FFQ. Intakes of foods were compared with Spanish food-based dietary guidelines. Intake inadequacy for nutrients was assessed using the Dietary Reference Intakes of the US Institute of Medicine. SETTING: Valencia, Spain. SUBJECTS: We studied 822 pregnant women who had information on dietary intake during their first trimester of pregnancy. RESULTS: More than 50% of pregnant women did not meet the guidelines for cereals and legumes; reported intakes of carbohydrates, n-3 and n-6 fatty acids were below recommendations and exceeded the total fat intake according to dietary references. Dietary inadequacy for folate, Fe and vitamin E ranged from 99% to 68%. Vegetable intake was related to age only. Younger and less educated women showed lower intakes of protein and n-3 fatty acids and higher intakes of trans-fatty acids as well as greater inadequacy for micronutrients. Spanish women reported lower intakes of fruit and carbohydrates and higher intakes of protein, total fat, SFA, MUFA and n-3 fatty acids compared with their foreign-born counterparts. CONCLUSIONS: Women in the studied area have inadequate intakes of several nutrients relevant during pregnancy. Age, education and country of origin are factors significantly related to dietary intake and adequacy.

Prenatal exposure to mercury and infant neurodevelopment in a multicenter cohort in Spain: study of potential modifiers.

Vulnerability of the central nervous system to mercury is increased during early development. This study aimed to evaluate whether cord blood total mercury levels may have a negative effect on both mental and psychomotor development in a maternal-birth cohort from moderate-high fish consumption areas. Study subjects were 1,683 child participants in the INMA (Environment and Childhood) Project from 4 areas of Spain between 2003 and 2010. Cord blood total mercury levels were analyzed by atomic absorption spectrometry. Infant neurodevelopment was assessed around age 14 months by the Bayley Scales of Infant Development. Sociodemographic, lifestyle, and dietary information was obtained by questionnaire during pregnancy. The geometric mean of total mercury levels was 8.4 µg/L (95% confidence interval (CI): 8.1, 8.7). In multivariate analysis, a doubling in total mercury levels did not show an association with mental (ß = 0.1, 95% CI: -0.68, 0.88) or psychomotor (ß = -0.05, 95% CI: -0.79, 0.68) developmental delay; however, stratified findings by sex suggest a negative association between prenatal exposure to total mercury and psychomotor development among female infants (ß = -1.09, 95% CI: -2.21, 0.03), although follow-up is required to confirm these results.

Social factors associated with nitrogen dioxide (NO2) exposure during pregnancy: the INMA-Valencia project in Spain.

Numerous studies have focused on the effects of exposure to air pollution on health; however, certain subsets of the population tend to be more exposed to such pollutants depending on their social or demographic characteristics. In addition, exposure to toxicants during pregnancy may play a deleterious role in fetal development as fetuses are especially vulnerable to external insults. The present study was carried out within the framework of the INMA (Infancia y Medio Ambiente or Childhood and the Environment) multicenter cohort study with the objective of identifying the social, demographic, and life-style factors associated with nitrogen dioxide (NO(2)) exposure in the subjects in the cohort. The study comprised 785 pregnant women who formed part of the INMA cohort in Valencia, Spain. Outdoor levels of NO(2) were measured at 93 sampling sites spread over the study area during four different sampling periods lasting 7 days each. Multiple regression models were used for mapping outdoor NO(2) throughout the area. Individual exposure was assigned as: 1) the estimated outdoor NO(2) levels at home, and 2) the average of estimated outdoor NO(2) levels at home and work, weighted according to the time spent in each environment. The subjects' socio-demographic and life-style information was obtained through a questionnaire. In the multiple linear analyses, the outdoor NO(2) levels assigned to each home were taken to be the dependent variable. Other variables included in the model were: age, country of origin, smoking during pregnancy, parity, season of the year, and social class. These same variables remained in the model when the dependent variable was changed to the NO(2) levels adjusted for the subjects' time-activity patterns. We found that younger women, those coming from Latin American countries, and those belonging to the lower social strata were exposed to higher NO(2) levels, both as measured outside their homes as well as when time-activity patterns were taken into account. These subgroups also have a higher probability of being exposed to NO(2) levels over 40 µg/m(3), which is the annual limit for maximum safe exposure, as established by European Directive 2008/50/EC.

[Folic acid intake from diet and supplements in a population of pregnant women in Valencia, Spain]. / Ingesta dietética y de suplementos de ácido fólico en mujeres embarazadas de Valencia.

BACKGROUND AND OBJECTIVES: We examined the dietary intake and the use of supplements of folic acid (FA) in a cohort of pregnant women. We also explored the factors associated with non-compliance of both the recommended intake (RI) of 600 µg/day and the supplement use of 400 µg/day provided to prevent neural tube defects (NTD). PATIENTS AND METHODS: We studied 782 pregnant women from the INMA-Valencia cohort. The dietary intake was estimated using a food frequency questionnaire in two periods of pregnancy; from preconception to the second month and from the 3rd to the 7th month. Information on supplement use was also collected which allowed us to estimate the total FA intake (diet+supplements). We explored factors associated with non-compliance of the recommendations by logistic regression. RESULTS: The periconceptional mean daily FA intake was 304 µg/day. FA supplements were taken by 19.2, 30.2 and 66.2% of women in preconception, first and second month of pregnancy, respectively. Among women using supplements in periconception, 30% exceeded the tolerable upper intake level (UL) of 1.000 µg/day. Non-compliance with RI was more common among women of foreign origin, of low educational level, who smoked, with unplanned pregnancy, who did not visit a private gynaecologist, who had had children or without previous medical illness. CONCLUSIONS: Diet by itself is not sufficient to reach RI for FA during pregnancy and many women initiate supplement use after the recommended period and inadequately. The youngest women, with lowest educational attainment and unplanned pregnancies are more likely not to comply.

Ingesta dietética y de suplementos de ácido fólico en mujeres embarazadas de Valencia / Folic acid intake from diet and supplements in a population of pregnant women in Valencia, Spain

Fundamento y objetivos: Analizar la ingesta dietética y de suplementos de ácido fólico (AF) durante el embarazo y los factores asociados al incumplimiento de la ingesta recomendada (IR) de 600μg/d y al incumplimiento de 400μg/d de suplementos para prevenir los defectos del tubo neural. Pacientes y método: Se incluyeron a 782 embarazadas de la cohorte INMA-Valencia. La ingesta dietética se estimó mediante un cuestionario de frecuencia alimentaria en 2 períodos de embarazo, desde preconcepción al mes 2 y desde el mes 3–7. También se recogió información de la suplementación y se estimó la ingesta total de AF (dieta+suplementos). Usando regresión logística múltiple se exploraron los factores asociados al incumplimiento de las recomendaciones. Resultados: La ingesta dietética media periconcepcional de AF fue de 304μg/d. Un 19,2%, 30,2% y 66,2% de embarazadas tomaron suplementos de AF en preconcepción, primer y segundo mes, respectivamente. Por otra parte, alrededor del 30% de las mujeres que tomaban suplementos de AF en periconcepción superó el límite superior tolerable de 1.000μg/d. El ser no española, de bajo nivel de estudios, fumadora, no planificar el embarazo, no haber visitado a ginecólogo privado, haber tenido hijos y no haber tenido antecedentes médicos previos, se asoció al incumplimiento de la IR. Conclusiones: La dieta sola es insuficiente para alcanzar las IR de AF, puesto que la suplementación se hace tarde y mal. La situación se agrava en mujeres jóvenes, de menor nivel educativo y embarazo no planificado (AU)

Setting: Hospital de Sant Boi, a 126-bed general hospital in Sant Boi de Llobregat in the province of Barcelona. Management measures: decreased presurgical stay, increased use of ambulatory surgical procedures, and increased use of a medical short-stay unit. Variables studied: emergency department admissions, hospital ward admissions, admissions for ambulatory surgical procedures, number of days in which at least 1 patient was in the emergency department at 8 A.M. while waiting for a bed, mean hospital stay, and admissions and average time spent in the short-stay unit. Results: A total of 57140 patients were admitted to the emergency department in the first period and 71280 in the second period; 4840 (8.4%) were admitted to hospital in the first period and 5385 (7.5%) in the second. The average length of stay was 5.19 days in the first period and 4.54 days in the second (P<.001). At least 1 patient was waiting in the emergency department for a hospital bed to become available on 86 days in the first period (307 patients/year) and11 days in the second period (26 patients/year). Conclusions: The management measures applied in this case were effective in reducing the number of patients held in the emergency department while waiting for admission (AU)

Air pollution exposure during pregnancy and reduced birth size: a prospective birth cohort study in Valencia, Spain.

BACKGROUND: Maternal exposure to air pollution has been related to fetal growth in a number of recent scientific studies. The objective of this study was to assess the association between exposure to air pollution during pregnancy and anthropometric measures at birth in a cohort in Valencia, Spain. METHODS: Seven hundred and eighty-five pregnant women and their singleton newborns participated in the study. Exposure to ambient nitrogen dioxide (NO2) was estimated by means of land use regression. NO2 spatial estimations were adjusted to correspond to relevant pregnancy periods (whole pregnancy and trimesters) for each woman. Outcome variables were birth weight, length, and head circumference (HC), along with being small for gestational age (SGA). The association between exposure to residential outdoor NO2 and outcomes was assessed controlling for potential confounders and examining the shape of the relationship using generalized additive models (GAM). RESULTS: For continuous anthropometric measures, GAM indicated a change in slope at NO2 concentrations of around 40 microg/m3. NO2 exposure >40 microg/m3 during the first trimester was associated with a change in birth length of -0.27 cm (95% CI: -0.51 to -0.03) and with a change in birth weight of -40.3 grams (-96.3 to 15.6); the same exposure throughout the whole pregnancy was associated with a change in birth HC of -0.17 cm (-0.34 to -0.003). The shape of the relation was seen to be roughly linear for the risk of being SGA. A 10 microg/m3 increase in NO2 during the second trimester was associated with being SGA-weight, odds ratio (OR): 1.37 (1.01-1.85). For SGA-length the estimate for the same comparison was OR: 1.42 (0.89-2.25). CONCLUSIONS: Prenatal exposure to traffic-related air pollution may reduce fetal growth. Findings from this study provide further evidence of the need for developing strategies to reduce air pollution in order to prevent risks to fetal health and development.

Iodine intake and maternal thyroid function during pregnancy.

BACKGROUND: An adequate iodine intake during pregnancy is essential for the synthesis of maternal thyroid hormones and normal brain development in the fetus. Scant evidence is available on the effects and safety of iodine supplementation during pregnancy in areas with adequate or mildly deficient iodine intake. We examined the association of maternal iodine intake and supplementation with thyroid function before 24 weeks of gestation in population-based samples from 3 different areas in Spain. METHODS: A cross-sectional study of 1844 pregnant women (gestational age range 8-23 weeks) was carried out in 3 areas in Spain (Guipúzcoa, Sabadell, Valencia), during the period 2004-2008. We measured levels of free thyroxine and thyroid-stimulating hormone (TSH) in serum, iodine in a spot urine sample, and questionnaire estimates of iodine intake from diet, iodized salt and supplements. Adjusted associations were assessed by multiple linear regression and logistic regression analyses. RESULTS: There was an increased risk of TSH above 3 muU/mL in women who consumed 200 microg or more of iodine supplements daily compared with those who consumed less than 100 microg/day (adjusted odds ratio = 2.5 [95% confidence interval = 1.2 to 5.4]). We observed no association between urinary iodine and TSH levels. Pregnant women from the area with the highest median urinary iodine (168 microg/L) and highest supplement coverage (93%) showed the lowest values of serum free thyroxine. (geometric mean = 10.09 pmol/L [9.98 to 10.19]). CONCLUSIONS: Iodine supplement intake in the first half of pregnancy may lead to maternal thyroid dysfunction in iodine-sufficient or mildly iodine-deficient populations.

Fish consumption during pregnancy, prenatal mercury exposure, and anthropometric measures at birth in a prospective mother-infant cohort study in Spain.

BACKGROUND: Birth size has been shown to be related to maternal fish intake, although the results are inconsistent. OBJECTIVE: The objective was to assess the association of consumption of different types of fish and prenatal mercury exposure with birth weight, birth length, and classification as small for gestational age (SGA) in newborns. DESIGN: Cord blood total mercury was measured in 554 newborns in a population-based cohort born from 2004 to 2006. Fish consumption was classified in 4 frequency categories (<1 portion/mo, 1-3 portions/mo, 1 portion/wk, and > or =2 portions/wk). RESULTS: When multivariate models were adjusted, newborns in the higher quartile of total mercury weighed 143.7 g less (95% CI: -251.8, -35.6; P for trend = 0.02) and had higher odds of being SGA for length (odds ratio: 5.3; 95% CI: 1.2, 23.9; P from likelihood ratio test = 0.03) without a linear relation (P for trend = 0.13) compared with those in the lowest quartile. Mothers consuming >/=2 portions/wk of canned tuna had newborns who weighed more than those who consumed <1 portion/mo (P for trend = 0.03) and a lower risk of having infants who were SGA for weight (P for trend = 0.01). Consumption of > or =2 portions/wk of large oily fish was associated with a higher risk of being SGA for weight and consumption of lean fish with a lower risk of being SGA for length compared with the consumption of <1 portion/mo, but in neither case was there a linear relation (P for trend >0.05). CONCLUSIONS: The role of fish in fetal growth depends on the amount and type of fish consumed. The findings for mercury warrant further investigation in other settings.

Vegetable but not fruit intake during pregnancy is associated with newborn anthropometric measures.

We examined the relationship between consumption of fruit and vegetables during pregnancy and anthropometric measures at birth in a general population mother-infant cohort in Valencia, Spain. A total of 787 infants born between May 2004 and February 2006 were included. Fruit and vegetable consumption during pregnancy was assessed by a FFQ administered using an in-person interview. We used multiple linear regression to assess associations between fruit and vegetable intake (in quintiles) and birth weight and length adjusted for sex and gestational age, and logistic regression to assess being small for gestational age (SGA) in weight and SGA in length, defined as adjusted birth weight or length below the 10th percentile. A linear relationship was found between vegetable consumption and having a SGA (weight) and SGA (length) baby. Women in the lowest quintile of vegetable intake during the first trimester had a higher odds of having a SGA (weight) baby than women in the highest quintile [odds ratio (OR), 3.7; 95% CI: 1.5-8.9; P-trend < 0.001] and had a higher odds of having an SGA (length) baby in the third trimester (OR, 5.5; 95% CI: 1.7-17.7; P-trend = 0.04) in multivariate analysis. We found a nonmonotonic relationship between adjusted birth weight and length and vegetable consumption during the first trimester; newborns in the 2 lowest quintiles of intake had a significantly lower weight and length than those in the 4th quintile. There was no association between fruit consumption and birth outcomes. Our findings indicate that vegetable consumption throughout pregnancy may have a beneficial effect on fetal growth.

Prenatal exposure to mercury in a prospective mother-infant cohort study in a Mediterranean area, Valencia, Spain.

BACKGROUND: Mercury (Hg) is a ubiquitous pollutant that negatively affects fetal and child neurodevelopment at accidental high-dose exposure. Some studies indicate that Mediterranean populations could be at risk of prenatal exposure to mercury through fish consumption. OBJECTIVES: To assess the prenatal exposure to total mercury (T-Hg), both inorganic and organic, in newborns by analyzing the T-Hg concentration in cord blood, and to evaluate the role of maternal fish consumption in this exposure. METHODS: In the context of a multi-center project (INMA project), a prospective birth cohort was set up in Valencia, Spain, from 2005 to 2006. A total of 253 newborns were included in this study. We compared cord blood T-Hg concentration by levels of fish intake assessed by a food frequency questionnaire completed at 28-32 weeks of gestation. Maternal covariates were obtained through a questionnaire. RESULTS: The geometric mean of T-Hg at birth was 9.9 microg/L (95% CI: 9.0, 10.8). Seventy five percent of cord blood samples were above the estimated level assumed to be without appreciable harm (5.8 microg/L). Women who consumed a portion of large oily fish, lean fish, or mixed fried fish two or more times per week had mean cord blood levels 1.6, 1.4 and 1.3 times higher, respectively, than those who rarely or never consumed fish. Other factors such as the mother's age, country of origin, smoking and season of delivery were also significantly and independently associated with cord blood T-Hg concentrations. CONCLUSIONS: Newborns from a Mediterranean area presented elevated levels of T-Hg in cord blood. Higher concentrations of T-Hg were related to maternal fish intake, particularly in the case of large oily fish species.

Intoxicaciones por neurolépticos / No disponible

Cada vez es más frecuente el uso de neurolépticos en la infancia y adolescencia, y las intoxicaciones por estos fármacos no son despreciables. Unas veces son debidas al aumento de las dosis de forma accidental o a ingestiones accidentales en los niños más pequeños que toman la medicación de sus familiares. Asimismo, entre los niños más mayores y adolescentes se describen casos de intentos suicidas o de llamar la atención. Se ha hecho una revisión de las intoxicaciones por neurolépticos en la infancia y en la adolescencia, incluyendo las exposiciones tóxicas registradas en el Servicio de Información Toxicológica (SIT). También se describen los diferentes principios activos antipsicóticos, mecanismos de acción, toxicocinética, manifestaciones clínicas de la intoxicación aguda y medidas terapéuticas (AU)

Neuroleptic use in both childhood and adolescence is increasing, and the toxic exposures by these drugs are not negligible. In several cases neuroleptic intoxications are due to therapeutic errors or to accidental ingestion of parent medications by children. Other toxic exposures are the result of suicidal attempts, essentially in adolescents. We have reviewed the neuroleptic intoxications in children and adolescents, including the toxic exposures registered in the Spanish Poison Control Centre (SPCC). Antipsychotic compounds, mechanisms of action, kinetics, clinical manifestations of acute intoxications and therapeutic measures are also described (AU)

Child health and the environment: the INMA Spanish Study.

The INMA (INfancia y Medio Ambiente [Environment and Childhood]) is a population-based cohort study in different Spanish cities, that focuses on prenatal environmental exposures and growth, development and health from early fetal life until childhood. The study focuses on five primary areas of research: (1) growth and physical development; (2) behavioural and cognitive development; (3) asthma and allergies; (4) sexual and reproductive development; and (5) environmental exposure pathways. The general aims of the project are: (1) to describe the degree of individual prenatal exposure to environmental pollutants, and the internal dose of chemicals during pregnancy, at birth and during childhood in Spain; (2) to evaluate the impact of the exposure to different contaminants on fetal and infant growth, health and development; (3) to evaluate the role of diet on fetal and infant growth, health and development; and (4) to evaluate the interaction between persistent pollutants, nutrients and genetic determinants on fetal and infant growth, health and development. Extensive assessments will be carried out on 3100 pregnant women and children. Data will be collected by physical examinations, questionnaires, interviews, ultrasound and biological samples. Pregnant women are being assessed at 12, 20 and 32 weeks of gestation to collect information about environmental exposures and fetal growth. The children will be followed until the age of 4 years.

[The Environment and Childhood Research Network ("INMA" network): study protocol]. / La Red de Investigación "Infancia y Medio Ambiente" (Red INMA): protocolo de estudio.

Increasingly greater evidence exists as to the influence which diet and exposure to low doses of toxic substances during the prenatal stage and early childhood has on health and well-being throughout later stages of life. Following the WHO and European Union recommendations in 2003, the Cooperative Environment and Childhood Research Network was set up to study the effects of the environment and diet on fetal and early childhood development in different geographical areas of Spain. This Network integrates different multidisciplinary research groups and is comprised of six cohorts--three pre-existing and three de novo--which will follow up prospectively 3,600 pregnant women, from the start of pregnancy up to age 4-6 years of the child. This network's general objectives are: (1) To describe individual exposure to toxic substances in the environment during gestation and early childhood. (2) To evaluate the effects of exposure to toxic substances and diet on fetal and early childhood development. (3) To evaluate the interaction among toxic, nutritional and genetic factors in fetal and early childhood development. The follow-up is done every three months during gestation, at birth, at age one and up to age four or six. The information is gathered by means of questionnaires, clinical data, physical examinations, echographs, biomarkers and environmental measurements. The general characteristics of the network and a description of the current situation of each one of the cohorts are provided in this study.

La Red de Investigación «Infancia y Medio Ambiente» (Red INMA): protocolo de estudio / The environment and childhood research network («INMA» network): study protocol

Cada vez existe mayor evidencia de la influencia de la dieta y dela exposición a dosis bajas de tóxicos durante la etapa prenatal y primerainfancia sobre la salud y el bienestar en etapas posteriores de lavida. Siguiendo las recomendaciones de la OMS y de la Unión Europeaen el año 2003 se constituyó la Red de Investigación CooperativaInfancia y Medio Ambiente para estudiar los efectos del medioambiente y la dieta en el desarrollo fetal e infantil en diversas zonasgeográficas en España. La Red integra diversos grupos multidisciplinaresde investigación y está constituida por seis cohortes, trespreexistentes y tres de novo, que seguirán de forma prospectiva a3.600 mujeres embarazadas, desde el inicio del embarazo hasta los 4-6 años del niño. Los objetivos generales de la red son: (1) Describirla exposición individual a tóxicos ambientales durante la gestación yla primera infancia. (2) Evaluar los efectos de la exposición a tóxicosy de la dieta en el desarrollo fetal e infantil. (3) Evaluar la interacciónentre factores tóxicos, nutricionales y genéticos en el desarrollo fetale infantil. El seguimiento se realiza en cada trimestre de la gestación,al nacimiento, al año y hasta los cuatro o seis años del niño. La información se recoge mediante cuestionarios, datos clínicos, exploración física, ecografías, biomarcadores y mediciones ambientales. Eneste trabajo se presentan las características generales de la red y sedescribe la situación actual de cada una de las cohortes
