Cognitive-behavioral therapy for anxiety disorders in children and adolescents: a systematic review of follow-up studies

Objective To conduct a systematic review about the long-term response to cognitive-behavioral therapy (CBT) for anxiety disorders (ADs) in children and adolescents. Methods The PubMed and ISI Web of Science databases were consulted. Search in the databases was performed in November 2012 and included cohort studies after CBT for ADs in children and adolescents with a follow-up period over 12 months. Results A total of 10 papers met the inclusion criteria. The follow-up period ranged from 12 months to 13 years and the results generally showed maintenance of the short-term benefits with CBT. However, the studies presented limitations, especially regarding methods, such as lack of a control group and losses to follow-up. Conclusion The long-term benefits of CBT were identified, however it would be interesting to conduct other studies with more frequent assessment periods, in order to minimize losses to follow-up, in addition to evaluating children and adolescents in the various stages of their development.

Lipid profile of nutrition students and its association with cardiovascular disease risk factors

OBJECTIVE: To describe the lipid profile and to verify its relationship with cardiovascular disease risk factors in students at a public university in São Paulo. METHODS: After obtaining clinical, anthropomorphic, and lipid profile data from 118 students, variables of the lipid profile were related to other risk factors. RESULTS: The mean age of the students was 20.3 years (SD=1.5). The risk of cardiovascular disease was characterized by a positive family history of ischemic heart disease in 38.9%; sedentariness in 35.6%; limiting and increased total and LDL-C cholesterol levels in 17.7% and 10.2%, respectively; decreased HDL-C levels in 11.1%; increased triglyceride levels in 11.1%; body mass index >25 in 8.5%, and smoking in 6.7% of the subjects. Students' diet was found to be inadequate regarding protein, total fat, saturated fat, sodium, and fiber contents. A statistically significant association between cholesterol and contraceptive use, between HDL-C and contraceptive use, age and percent body fat, and triglycerides and percent lean weight was observed. CONCLUSION: A high prevalence of some risk factors of cardiovascular disease as well as the association between these factors with altered lipid profiles was observed in the young population studied.

Infants’ behavioral and physiological profile and mother–infant interaction

This study aims to (a) identify and profile groups of infants according to their behavioral and physiological characteristics, considering their neurobehavioral organization, social withdrawal behavior, and endocrine reactivity to stress, and to (b) analyze group differences in the quality of mother–infant interaction. Ninety seven 8-week-old infants were examined using the Neonatal Behavioral Assessment Scale and the Alarm Distress Baby Scale. Cortisol levels were measured both before and after routine inoculation between 8 and 12 weeks. At 12 to 16 weeks mother–infant interaction was assessed using the Global Rating Scales of Mother–Infant Interaction. Three groups of infants were identified: (a) ‘‘withdrawn’’; (b) ‘‘extroverted’’; (c) ‘‘underaroused.’’ Differences between them were found regarding both infant and mother behaviors in the interaction and the overall quality of mother–infant interaction. The identification of behavioral and physiological profiles in infants is an important step in the study of developmental pathways.

Mother’s depression at childbirth does not contribute to the effects of antenatal depression on neonate’s behavioral development

Background: Maternal depression is a worldwide phenomenon that has been linked to adverse developmental outcomes in neonates. Aims: To study the effect of antenatal depression (during the third trimester of pregnancy) on neonate behavior, preference, and habituation to both the mother and a stranger’s face/voice. To analyze mother’s depression at childbirth as a potential mediator or moderator of the relationship between antenatal depression and neonate behavioral development. Method: A sample of 110 pregnant women was divided in 2 groups according to their scores on the Edinburgh Postnatal Depression Scale during pregnancy (EPDS; ≥10, depressed; <10, non-depressed). In the first 5 days after birth, neonatal performance on the Neonatal Behavioral Assessment Scale (NBAS) and in the ‘Preference and habituation to the mother’s face/voice versus stranger’ paradigm was assessed; each mother filled out an EPDS. Results: Neonates of depressed pregnant women, achieved lower scores on the NBASs (regulation of state, range of state, and habituation); did not show a visual/auditory preference for the mother’s face/voice; required more trials to become habituated to the mother’s face/voice; and showed a higher visual/auditory preference for the stranger’s face/voice after habituation compared to neonates of non-depressed pregnant women. Depression at childbirth does not contribute to the effect of antenatal depression on neonatal behavioral development. Conclusion: Depression even before childbirth compromises the neonatal behavioral development. Depression is a relevant issue and should be addressed as a routine part of prenatal health care.

Brazelton Neonatal Behavioral Assessment Scale: a psychometric study in a Portuguese sample

Background: The Neonatal Behavioral Assessment Scale (NBAS, Brazelton & Nugent, 1995) is an instrument conceived to observe the neonatal neurobehavior. Data analysis is usually performed by organizing items into groups. The most widely used data reduction for the NBAS was developed by Lester, Als, and Brazelton (1982). Objective: Examine the psychometric properties of the NBAS items in a sample of 213 Portuguese infants. Method: The NBAS was performed in the first week of infant life (3 days±2) and in the seventh week of life (52 days±5). Results: Principal component analyses yielded a solution of four components explaining 55.13% of total variance. Construct validity was supported by better neurobehavioral performance of 7-week-old infants compared with 1-week-old infants. Conclusion: Changes in the NBAS structure for the Portuguese sample are suggested compared to Lester factors in order to reach better internal consistency of the scale.

Postpartum Depression: Is it a condition affecting the mother-infant interaction and the development of the child across the first year of life?

Noting that maternal depression is common during a baby's first year, this study examined the interaction of depressed and non-depressed mother-child dyads. A sample of 26 first-time mothers with postpartum depression at the third month after birth and their 3-month-old infants was compared to a sample of 25 first-time mothers with no postpartum depression at the third month after birth and their 3-month-old infants. The observations were repeated at 6 months and again at 12 months postpartum. The samples were compared for differences in mother interaction behavior, mother's infant care, mother's concern with the baby, infant behavioral difficulties, infant mental and motor development, and infant behavior with the observer. Among the findings are the following: (1) depressed mothers' interaction behavior and care of their infants are less adequate than the non-depressed mothers' interaction behavior and care of their infants at 3, 6, and 12 months postpartum; (2) infants' interaction behaviors during feeding and face-to-face interaction with depressed mothers are less adequate than infants' interactions with non-depressed mothers at 3, 6, and 12 months postpartum; (3) mother-infant interactions are less adequate in the depressed mother dyads than the non-depressed dyads at 3, 6, and 12 months postpartum; (4) depressed mothers are less concerned about their infants than non-depressed mothers at 3, 6, and 12 months postpartum; (5) infants of depressed mothers have more behavioral difficulties at 3, 6, and 12 months postpartum than infants of non-depressed mothers; (6) infants of depressed mothers had lower mental and motor development rates at 6 and 12 months postpartum than infants of non-depressed mothers; and (7) infants of non-depressed mothers behaved in a more positive way with the observer than the infants of depressed mothers.

Exposición prenatal al alcohol y síndrome de hiperactividad con déficit de la atención: un abordaje conductual, farmacológico y bioquímico. Alcohol prenatal exposure and attention deficit with hyperactivity disorder: behavioral, pharmacological and biochemical approaches.

El Trastorno por Déficit de Atención con Hiperactividad (ADHD) es un síndrome conductual de origen orgánico, que se manifiesta principalmente en niños. Está caracterizado por distracción moderada a severa, períodos de atención breve, hiperactividad, inestabilidad emocional e impulsividad. Los tratamientos se basan "paradójicamente" en psicoestimulantes. Las sustancias mas empleadas son metilfenidato y anfetamina. La sintomatología indica un mal funcionamiento en los circuitos dopaminérgicos que sería el resultado de factores genéticos como ambientales, ya que es común encontrar ADHD en niños expuestos prenatalmente al alcohol. Los modelos animales son importantes para estudiar patologías de etiología desconocida, en este sentido, estudios de nuestro laboratorio indican que ratones deficientes en p35 son hiperactivos y responden paradojalmente a psicoestimulantes. Cdk5/p35 participa en el desarrollo neuronal, liberación de vesículas, señales dopaminérgicas, etc. Además resultados preliminares indican que la experiencia prenatal con una dosis etílica moderada durante la gestación tardía, es suficiente para incrementar los patrones de actividad locomotora, semejantes a los descriptos en los modelos animales de ADHD. De acuerdo a estas consideraciones hipotetizamos que la exposición etílica prenatal a dosis moderadas y durante un periodo acotado de la gestación tardía, resulta en un patrón conductual similar al descripto en modelos de ADHD. Asimismo, drogas psicoestimulantes pueden revertir dichos efectos. Por otra parte, proponemos que estas alteraciones son consecuencia de los efectos ocasionados por el insulto etílico sobre el equilibrio en el funcionamiento del sistema de neurotransmisión dopaminérgio mesolímbico/cortical. Teniendo en cuenta que la etiología del ADHD aun no se conoce, el desarrollo de modelos animales, que recapitulen características clínicas de este trastorno, constituye una herramienta muy poderosa para el estudio de los mecanismos celulares y moleculares que subyacen a este síndrome, por lo tanto, en este proyecto nos proponemos obtener evidencias acerca de las alteraciones originadas a partir de efectos deletéreos de la exposición etílica prenatal, que recapitulan el desarrollo de fenotipos conductuales y bioquímicos descriptos en modelos para ADHD. Específicamente nos proponemos determinar, por medio de experimentos conductuales, si la exposición a distintas dosis moderadas de alcohol durante un periodo acotado de la gestación tardía, son suficientes para generar alteraciones conductuales características de ADHD y establecer si metilfenidato y anfetamina, son capaces de revertirlas. Evaluar, mediante métodos bioquímicos, si este modelo involucra cambios en algunos de los componentes claves de la neurotransmisión dopaminérgica, tales como niveles de dopamina y sus metabolitos, niveles de expresión de tirosina-hidroxilasa, de receptores y transportador de dopamina, del complejo cdk5/p35, entre otros. Esperamos recapitular características análogas a las observadas en sujetos diagnosticados con ADHD y que el tratamiento con psicoestimulantes re-establezca los niveles de conducta normales. Mediante ensayos bioquímicos, esperamos encontrar mayores niveles de dopamina en tejido estriatal, acompañados con un aumento en los niveles de sus metabolitos y mediante western blot y ensayos de actividad esperamos encontrar mayor nivel de expresión en D1, menor de DAT y alteraciones en la normal actividad y expresión de cdk5/p35, que podrían explicar los resultados comportamentales esperados. Dada la alta prevalencia de ADHD y que estos jóvenes pacientes son medicados con psicoestimulantes, junto con la poca información sobre las respuestas neuroadaptativas del cerebro inmaduro, es importante investigar los mecanismos que subyacen las alteraciones neurofisiológicas de este trastorno. Estos abordajes experimentales resultan centrales para el desarrollo de terapias mas eficientes para el tratamiento de este síndrome.
