RESUMO
Prenatal and perinatal risk factors for perinatal brain damage frequently produce brain injuries in preterm and term infants. The early diagnosis and treatment of these infants, in the period of higher brain plasticity, may prevent the neurological and cognitive sequels that accompany these lesions. The Neurodevelopmental Research Unit at the Institute of Neurobiology of the National Autonomous University of Mexico has taken this endeavor. A multidisciplinary approach is followed. Pediatric, neurologic and rehabilitation clinical studies, MRI, EEG, visual and auditory evoked responses, and Bayley II evaluations are carried out initially. Infants are followed up to 8 years, with periodic appointments for evaluation and treatment. Katona's neurohabilitation method is used for initial diagnosis and treatment. Selective visual and auditory attention are explored from 3 months of age. This method was created in the Unit and, if deficiencies are observed, the method also describes the treatment to avoid subsequent alterations of these processes. Deficiencies in the acquisition of language are evaluated from 4 months of age, implementing treatment through instructions to parents on how they should teach their children to speak. This method has also been developed in the Unit and is in its validation process. In the MRI, we pay special attention to subtle and diffuse patterns, due to the high frequency with which they appear in contemporary cohorts at a national and international level. More than 80% of these infants showed abnormal MRI findings that should be taken into consideration. The outcome of children at 8 years old showed that 78%, 76% and 78% of extremely preterm, very preterm and late preterm, respectively, had a normal neurodevelopment. In term infants, only 69% had a normal neurodevelopment; in this group, the majority of infants had very severe brain lesions. Conclusions: It is necessary to evaluate, at an early age, all newborns with prenatal and perinatal risk factors for brain damage. Special attention should be payed to all premature newborns and those newborns who have been discharged from the intensive care unit.

Environmental factors are at least as important as genetic factors for the development of obsessive-compulsive symptoms (OCS), but the identification of such factors remain a research priority. Our study aimed to investigate the association between a broad scope of potential risk factors and OCS in a large community cohort of children and adolescents. We evaluated 1877 participants and their caregivers at baseline and after 3 years to assess various demographic, prenatal, perinatal, childhood adversity, and psychopathological factors. Mean age at baseline was 10.2 years (SD 1.9) and mean age at follow-up was 13.4 years (SD 1.9). Reports of OCS at baseline and follow-up were analyzed using latent variable models. At preliminary regression analysis, 15 parameters were significantly associated with higher OCS scores at follow-up. At subsequent regression analysis, we found that eight of these parameters remained significantly associated with higher follow-up OCS scores while being controlled by each other and by baseline OCS scores. The significant predictors of follow-up OCS were: lower socioeconomic status (p = 0.033); lower intelligence quotient (p = 0.013); lower age (p < 0.001); higher maternal stress level during pregnancy (p = 0.028); absence of breastfeeding (p = 0.017); parental baseline OCS (p = 0.038); youth baseline anxiety disorder (p = 0.023); and youth baseline OCS scores (p < 0.001). These findings may better inform clinicians and policymakers engaged in the mental health assessment and prevention in children and adolescents.

Objectives Although maternal attachment is an important predictor of infant developmental outcomes, little is known about its pre- and postnatal predictors. The purpose of this secondary data analysis is to assess several risk factors for maternal attachment at 6 months postpartum in a sample of Mexican women at risk of depression. The predictors included were prenatal depressive symptoms, pregnancy intendedness, partner relationship, social support, maternal history of childhood sexual abuse, and postpartum depressive symptoms. Methods A total of 156 pregnant women seeking antenatal care at three health centers were selected because they displayed depressive symptoms (CES-D ≥ 16) or had previously suffered depression. Women were interviewed during pregnancy and at 6 months postpartum. A step-wise multivariate logistic regression was conducted to evaluate the pre- and postpartum risk factors for postpartum depression related to low maternal attachment. Results Pre- and postpartum depressive symptoms increased the risk of low maternal attachment by factors of 3.00 and 3.97, respectively, compared with women who did not present these symptoms; low level of adjustment with the partner increased the risk by a factor of 3.11, low social support by a factor of 2.90, and CSA by a factor of 2.77. Conclusions for practice Prevention programs during pregnancy to reduce depressive symptoms should strengthen strategies to promote maternal attachment by improving partner relations and increasing social support. However, evidence shows that such programs alone are insufficient, so direct interventions should also be implemented. Women with a history of childhood sexual abuse should be given additional attention during prenatal care.
