Habileté de mentalisation chez les mères présentant un trouble de personnalité limite : orientation mentale maternelle lors d’interactions mère-bébé.

Contexte : Les personnes atteintes de trouble de personnalité limite (TPL) présenteraient un déficit de mentalisation, soit la capacité de percevoir et interpréter les états mentaux chez soi et chez l’autre. Dans le cadre de la relation mère-bébé, un tel déficit est susceptible d’entraîner des perturbations relationnelles ayant des conséquences néfastes sur le développement de l’enfant. L’orientation mentale se mesure par le biais des verbalisations du parent au sujet des états mentaux de son enfant et constitue donc un reflet de la mentalisation du parent durant cette interaction. Toutefois, aucune étude n’a encore investigué l’orientation mentale chez des mères avec TPL durant l’interaction avec leur bébé. Objectif : Le but de cette étude était d’évaluer l’orientation mentale de 38 mères en interaction avec leur enfant âgé de 12 mois, incluant 10 mères atteintes de TPL et 28 sans diagnostic psychiatrique. Méthode: L’orientation mentale maternelle fut évaluée à partir de vidéos d’interaction mère-enfant dans un contexte de jeu libre. Le TPL a été identifié à l’aide du Structured Clinical Interview for DSM-III-R Personality Disorders (SCID-II). Résultats: Les mères atteintes de TPL ne se sont pas distingué concernant la fréquence de commentaires faisant référence aux états mentaux de leur bébé. Toutefois, les commentaires mentaux des mères souffrant de TPL se sont avérés être 4.7 fois plus fréquemment jugés non-appropriés à l’état mental de l’enfant comparés à ceux des mères sans diagnostic psychiatrique. Conclusions : Les commentaires mentaux des mères atteintes de TPL semblent plus fréquemment empreints d’erreurs d’interprétation des états mentaux de leur enfant, ce qui pourrait poser un risque pour le développement de l’enfant.

Análisis de los períodos de regresión y transición en el primer año de vida

Aquesta tesi està centrada en l'estudi dels períodes de regressió i transició. A partir dels treballs de van de Rijt-Plooij & Plooij (1992) sobre els períodes de regressió, l'autor analitza les característiques comportamentals d'aquests períodes i la relació que tenen amb els períodes de transició. Els períodes de regressió s'entenen com uns moments del desenvolupament durant els quals els nens perden la homeostasi del seu organisme i manifesten una sèrie de conductes pertorbadores per a la mare. El matrimoni Plooij manté que els períodes de regressió són la manifestació de les reorganitzacions cerebrals que tenen lloc durant el període postnatal, i constitueixen la base de les noves habilitats que el nen va adquirint. Així, doncs, l'augment de l'atenció que la mare dispensa al nen durant els períodes de regressió esdevé una font estimular imprescindible en els processos d'educació i culturalització de l'infant. Per tant, els períodes de regressió estan íntimament relacionats amb els períodes durant els quals apareixen nous comportaments qualitativament diferents dels anteriors, que es manifesten de forma ràpida i sobtada, permetent una certa sistematització del procés evolutiu, per la qual cosa s'han denominat transicions. Van de Rijt-Plooij & Plooij, i també nosaltres, considerem que els períodes de regressió són índexs dels períodes de transició. Per aquesta raó també s'han denominar reprogressions. Tanmateix, els períodes de regressió es poden convertir en una font de conflictes que, en situació de risc, poden degenerar en maltractament infantil i, fins i tot, esdevenir el germen de possibles patogènies. Com veiem, els conceptes de període de regressió i transició es troben a l'encreuament entre la fisiologia, la psicologia i la psicopatologia del desenvolupament i, el seu estudi establiria un pont interdisciplinar que contribuiria a la construcció d'un model biopsicosocial del desenvolupament. Els objectius del nostre estudi varen ser comprovar si els períodes descrits per van de Rijt-Plooij i Plooij (1992) també els podem observar en un grup de nens de la població catalana sense problemes socio-econòmics o sanitaris aparents. Per altra banda, vàrem voler comprovar si els períodes de regressió tenen relació amb els períodes de transició. El disseny d'investigació correspon a un model longitudinal i transversal. Es varen seguir -mitjançant entrevistes, qüestionaris i observacions- vint diades mare-nen durant catorze mesos, repartides en quatre cohorts de cinc diades cada una d'elles. Partint d'uns criteris establerts a priori per a la categorització dels períodes de regressió i transició, vàrem estudiar la temporalitat d'ambdós tipus de períodes. També s'ha aprofundit sobre les característiques comportamentals i dinàmiques dels períodes de regressió. Respecte les dades, els percentatges màxims dels períodes de regressió del nostre grup d'estudi han aparegut a les setmanes: 5, 8, 12-13, 18, 26-27, 35, 43 i 52. La mitjana setmanal de cada període ha sigut de dues setmanes. Les nostres dades confirmen les obtingudes en la investigació de van de Rijt-Plooij & Plooij. Tanmateix, també hem trobat diferències (els períodes de regressió de l'estudi holandès són més llargs i coincideixen més) que ens suggereixen que la cultura podrien estar actuant en la forma de presentació del períodes de regressió. Pel que fa a la relació entre els períodes de regressió i l'emergència de nous comportaments (períodes de transició), els resultats mostren que les freqüències màximes dels períodes de regressió sempre es troben poques setmanes abans de les freqüències màximes dels períodes de transició. Per tant, és possible que els períodes de regressió siguin indicadors dels períodes de transició.

Cost-effectiveness of a preventive counseling and support package for postnatal depression

Objectives: This study reports the cost-effectiveness of a preventive intervention, consisting of counseling and specific support for the mother-infant relationship, targeted at women at high risk of developing postnatal depression. Methods: A prospective economic evaluation was conducted alongside a pragmatic randomized controlled trial in which women considered at high risk of developing postnatal depression were allocated randomly to the preventive intervention (n = 74) or to routine primary care (n = 77). The primary outcome measure was the duration of postnatal depression experienced during the first 18 months postpartum. Data on health and social care use by women and their infants up to 18 months postpartum were collected, using a combination of prospective diaries and face-to-face interviews, and then were combined with unit costs ( pound, year 2000 prices) to obtain a net cost per mother-infant dyad. The nonparametric bootstrap method was used to present cost-effectiveness acceptability curves and net benefit statistics at alternative willingness to pay thresholds held by decision makers for preventing 1 month of postnatal depression. Results: Women in the preventive intervention group were depressed for an average of 2.21 months (9.57 weeks) during the study period, whereas women in the routine primary care group were depressed for an average of 2.70 months (11.71 weeks). The mean health and social care costs were estimated at 2,396.9 pound per mother-infant dyad in the preventive intervention group and 2,277.5 pound per mother-infant dyad in the routine primary care group, providing a mean cost difference of 119.5 pound (bootstrap 95 percent confidence interval [Cl], -535.4, 784.9). At a willingness to pay threshold of 1,000 pound per month of postnatal depression avoided, the probability that the preventive intervention is cost-effective is .71 and the mean net benefit is 383.4 pound (bootstrap 95 percent Cl, -863.3- pound 1,581.5) pound. Conclusions: The preventive intervention is likely to be cost-effective even at relatively low willingness to pay thresholds for preventing 1 month of postnatal depression during the first 18 months postpartum. Given the negative impact of postnatal depression on later child development, further research is required that investigates the longer-term cost-effectiveness of the preventive intervention in high risk women.

Mental health of parents caring for infants

The postpartum period is a sensitive time due to the presence and demands of the developing infant. The care provided by a mother to her infant during this period may be compromised if she is suffering from postnatal depression or postpartum psychosis. Evidence has been emerging which suggests that postnatal depression and postpartum psychoses have adverse effects on the quality of the mother-infant relationship and also on the infants subsequent cognitive and emotional development. Presented is a review of the literature relating to how these conditions impact on parenting and infant outcomes, what measures are in place to detect these conditions and evidence-based models of best clinical practice are proposed.

Making an effort to feel positive: insecure attachment in infancy predicts the neural underpinnings of emotion regulation in adulthood

Background: Animal research indicates that the neural substrates of emotion regulation may be persistently altered by early environmental exposures. If similar processes operate in human development then this is significant, as the capacity to regulate emotional states is fundamental to human adaptation. Methods: We utilised a 22-year longitudinal study to examine the influence of early infant attachment to the mother, a key marker of early experience, on neural regulation of emotional states in young adults. Infant attachment status was measured via objective assessment at 18-months, and the neural underpinnings of the active regulation of affect were studied using fMRI at age 22 years. Results: Infant attachment status at 18-months predicted neural responding during the regulation of positive affect 20-years later. Specifically, while attempting to up-regulate positive emotions, adults who had been insecurely versus securely attached as infants showed greater activation in prefrontal regions involved in cognitive control and reduced co-activation of prefrontal cortex and nucleus accumbens, consistent with relative inefficiency in the neural regulation of positive affect. Conclusions: Disturbances in the mother-infant relationship may persistently alter the neural circuitry of emotion regulation, with potential implications for adjustment in adulthood.

NEONATAL HANDLING AND THE MATERNAL ODOR PREFERENCE IN RAT PUPS: INVOLVEMENT OF MONOAMINES AND CYCLIC AMP RESPONSE ELEMENT-BINDING PROTEIN PATHWAY IN THE OLFACTORY BULB

Early-life environmental events, such as the handling procedure, can induce long-lasting alterations upon several behavioral and neuroendocrine systems. However, the changes within the pups that could be causally related to the effects in adulthood are still poorly understood. In the present study, we analyzed the effects of neonatal handling on behavioral (maternal odor preference) and biochemical (cyclic AMP response element-binding protein (CREB) phosphorylation, noradrenaline (NA), and serotonin (5-HT) levels in the olfactory bulb (OB)) parameters in 7-day-old male and female rat pups. Repeated handling (RH) abolished preference for the maternal odor in female pups compared with nonhandled (NH) and the single-handled (SH) ones, while in RH males the preference was not different than NH and SH groups. In both male and female pups, RH decreased NA activity in the OB, but 5-HT activity increased only in males. Since preference for the maternal odor involves the synergic action of NA and 5-HT in the OB, the maintenance of the behavior in RH males could be related to the increased 5-HT activity, in spite of reduction in the NA activity in the OB. RH did not alter CREB phosphorylation in the OB of both male and females compared with NH pups. The repeated handling procedure can affect the behavior of rat pups in response to the maternal odor and biochemical parameters related to the olfactory learning mechanism. Sex differences were already detected in 7-day-old pups. Although the responsiveness of the hypothalamic-pituitary-adrenal axis to stressors is reduced in the neonatal period, environmental interventions may impact behavioral and biochemical mechanisms relevant to the animal at that early age.

Mother’s experiences and perceptions of a continuous caring model with fathers after caesarean section : a qualitative study

Background: In Chile, mothers and newborns are separated after caesarean sections. The caesarean section rate in Chile is approximately 40%. Once separated, newborns will miss out on the benefits of early contact unless a suitable model of early newborn contact after caesarean section is initiated. Aim: To describe mothers experiences and perceptions of a continuous parental model of newborn care after caesarean section during mother-infant separation. Methods: A questionnaire with 4 open ended questions to gather data on the experiences and perceptions of 95 mothers in the obstetric service of Sótero Del Rio Hospital in Chile between 2009 and 2012. Data were analyzed using qualitative content analysis. Results: One theme family friendly practice after caesarean section and four categories. Mothers described the benefits of this model of caring. The fathers presence was important to mother and baby. Mothers were reassured that the baby was not left alone with staff. It was important for the mothers to see that the father could love the baby as much as the mother. This model of care helped create ties between the father and newborn during the period of mother-infant separation and later with the mother. Conclusions: Family friendly practice after caesarean section was an important health care intervention for the whole family. This model could be stratified in the Chilean context in the case of complicated births and all caesarean sections. Clinical Implications: In the Chilean context, there is the potential to increase the number of parents who get to hold their baby immediately after birth and for as long as they like. When the mother and infant are separated after birth, parents can be informed about the benefits of this caring model. Further research using randomized control trials may support biological advantages.

A maternidade, as relações mãe-filho e o inconsciente

Este trabalho tem como objetivo o estudo da vivência maternal em função da própria mulher como ser psíquico e de sua relação com o filho. Analisa-se teoricamente a importância do papel da mãe para a saúde psíquica das gerações futuras assim como também o significado psicológico de tal vivência para a mulher. O referencial teórico usado foi o psicanalítico; assim sendo, foram os fatores afetivos e inconscientes considerados primordiais na análise do problema. Apesar disso, também se fez uma abordagem ligeira de fatores sócio-culturais envolvidos na maternidade tentando-se contudo na medida do possível relacioná-los aos primeiros. Discute-se ao longo do trabalho o conceito de inconsciente e o significado de se aceitar a motivação inconsciente como principal determinante do comportamento humano. Aborda-se também segundo diversos teóricos a importância das primeiras relações mãe-filho salientando no jogo de relações o papel que cabe a mãe: Por fim, faz-se uma análise da disposição psíquica saudável ou não da mulher em relação a vivência maternal. Essa disposição é interpretada segundo aspectos afetivos e inconscientes relativos à história de suas primeiras relações com a própria mãe. Faz-se também uma análise das influências sociais momentâneas em relação a maternidade destacando-se a importância e necessidade de mudanças no modo de encará-la tanto a nível inconsciente como social para a integração psíquica da mulher com sua existência feminina e saúde psíquica das gerações futuras.
