Working memory in pregnant women: Relation to estrogen and antepartum depression.

This article is part of a Special Issue "Estradiol and cognition". Subjective changes in concentration and memory are commonly reported by women during the second or third trimesters of pregnancy, but the nature of the problem is poorly understood. We hypothesized that these self-reports might reflect difficulties in working memory (WM). It was further hypothesized that antepartum depression (depression arising during pregnancy) may play an etiological role, either on its own or due to secondary changes in endocrine function or sleep. Using WM tasks that emphasized executive control processes mediated by the prefrontal cortex (PFC) we compared pregnant women tested at 34-36 weeks of gestation (n = 28) with age- and education-matched non-pregnant controls (n = 26). All pregnant women were screened for depression. Evidence of a WM disturbance was found, and was evident only among pregnant women showing depressive symptoms. In contrast, pregnant women who were not depressed showed WM performance that equalled, or even significantly exceeded, non-pregnant controls. No significant differences were observed on control tests of other cognitive functions. Multiple regression revealed that serum estradiol concentrations, along with severity of depressive affect but not sleep disruption, significantly predicted variation in the WM scores. In agreement with studies of estradiol and WM in other contexts, higher estradiol was associated with better WM, while higher levels of depressive symptoms predicted poorer WM. We conclude that memory disturbance during gestation might not be as widespread as commonly believed, but can be seen among women experiencing antepartum depression. The high level of WM performance found in healthy, non-depressed, pregnant women is discussed from an adaptationist perspective.

Women and reproductive-related trauma.

Women are at higher risk for developing posttraumatic stress disorder (PTSD) than men, leading to significant psychosocial burden and healthcare-related costs. Research has shown an association between the negative impact of traumatic experiences and the reproductive life cycle in women. Pregnant women with a history of abuse/trauma frequently report intrusive reemergence of symptoms. Women who experience miscarriage may present with even higher prevalence rates of PTSD symptoms. Both psychologic and physiologic factors are believed to be relevant to the development of peripartum posttraumatic stress symptoms. Much less is known, however, about treatment. A case series of patients who presented with PTSD symptoms in the context of reproductive-related traumatic events (e.g., miscarriage, stillbirth) or who experienced reemergence of symptoms during pregnancy is presented, including treatment strategies.

[Postpartum depression: we know the risks, can it be prevented?]. / Depressão pós-parto: sabemos os riscos, mas podemos preveni-la?

In the past 20 years, there has been increasing recognition that for some women, pregnancy may be burdened with mood problems, in particular depression, that may impact both mother and child. With identification of risk factors for postpartum depression and a growing knowledge about a biologic vulnerability for mood change following delivery, research has accumulated on attempts to prevent postpartum depression using various psychosocial, psychopharmacologic, and hormonal strategies. The majority of psychosocial and hormonal strategies have shown little effect on postpartum depression. Notwithstanding, results from preliminary trials of interpersonal therapy, cognitive-behavioural therapy, and antidepressants indicate that these strategies may be of benefit. Information on prevention of postpartum depression using dietary supplements is sparse and the available evidence is inconclusive. Although a few studies show promising results, more rigorous trials are required. The abounding negative evidence in the literature indicates that postpartum depression cannot be easily prevented, yet.

[Trauma & the reproductive lifecycle in women]. / Trauma e o ciclo reprodutivo feminino.

Women are at significantly higher risk for developing post-traumatic stress disorder (PTSD) than men, resulting in increased psychosocial burden and healthcare related costs. Recent research has shown complex interactions between the impact of traumatic experiences, and the reproductive lifecycle in women. For example, women suffering from premenstrual dysphoric disorder (PMDD) who also report a history of sexual or physical abuse are more likely to present with different neuroendocrine reactivity to stressors, when compared to premenstrual dysphoric disorder subjects without prior history of trauma or abuse or non-premenstrual dysphoric disorder subjects. In addition, women with a history of abuse or trauma may experience re-emergence of symptoms during pregnancy. Lastly, females who experience miscarriage may present with even higher prevalence rates of post-traumatic stress disorder symptoms. In this manuscript we examine the existing data on gender differences in post-traumatic stress disorder, with particular focus on psychological and physiological factors that might be relevant to the development of symptoms after exposure to traumatic events associated with the reproductive life cycle. Current options available for the treatment of such symptoms, including group and counselling therapies and debriefing are critically reviewed.

Steroid concentrations in antepartum and postpartum saliva: normative values in women and correlations with serum.

BACKGROUND: Saliva has been advocated as an alternative to serum or plasma for steroid monitoring. Little normative information is available concerning expected concentrations of the major reproductive steroids in saliva during pregnancy and the extended postpartum. METHODS: Matched serum and saliva specimens controlled for time of day and collected less than 30 minutes apart were obtained in 28 women with normal singleton pregnancies between 32 and 38 weeks of gestation and in 43 women during the first six months postpartum. Concentrations of six steroids (estriol, estradiol, progesterone, testosterone, cortisol, dehydroepiandrosterone) were quantified in saliva by enzyme immunoassay. RESULTS: For most of the steroids examined, concentrations in antepartum saliva showed linear increases near end of gestation, suggesting an increase in the bioavailable hormone component. Observed concentrations were in agreement with the limited data available from previous reports. Modal concentrations of the ovarian steroids were undetectable in postpartum saliva and, when detectable in individual women, approximated early follicular phase values. Only low to moderate correlations between the serum and salivary concentrations were found, suggesting that during the peripartum period saliva provides information that is not redundant to serum. CONCLUSIONS: Low correlations in the late antepartum may be due to differential rates of change in the total and bioavailable fractions of the circulating steroid in the final weeks of the third trimester as a consequence of dynamic changes in carrier proteins such as corticosteroid binding globulin.

Hormones in the treatment of depression.

Several treatment strategies have been proposed for the management of depression in women. The occurrence of depression among females is often associated with periods of intense hormonal fluctuations, as observed in cases of premenstrual dysphoria, perinatal depression and with the development of depressive symptoms during the perimenopause. Various hormones including estrogen, progesterone, testosterone, dehydroepiandrosterone and thyroid hormones may exert modulatory effects on neurotransmitter pathways in the CNS. It has been postulated that abrupt changes in these hormones may negatively affect mood; conversely, hormonal interventions could potentially improve such symptoms. This article reviews the current literature on the impact of hormonal treatments for mood symptoms in women and preventative strategies for depression in women during the reproductive lifecycle.

Postpartum depression: we know the risks, can it be prevented?

Nos últimos vinte anos, houve um maior reconhecimento de que a gravidez em algumas mulheres pode ser complicada por problemas emocionais, particularmente depressão, causando um impacto significativo sobre a mãe e a criança. Com a identificação de fatores de risco para a depressão pós-parto e um aumento do conhecimento sobre a vulnerabilidade biológica para os transtornos de humor no período puerperal, um número crescente de estudos tem explorado meios de prevenir a depressão pós-parto, utilizando estratégias psicossociais, psicofarmacológicas e hormonais. A maior parte das intervenções psicossociais e hormonais tem mostrado pouco efeito para a prevenção da depressão pós-parto. Apesar disso, resultados de estudos preliminares sobre a terapia interpessoal, terapia cognitivo-comportamental e sobre o uso de antidepressivos indicam que estas intervenções podem resultar em algum benefício. Dados sobre o uso de suplementos dietéticos são limitados e com resultados pouco conclusivos. A excessiva quantidade de resultados negativos na literatura atual demonstra que a depressão pós-parto ainda não pode ser facilmente prevenida.

Trauma & the reproductive lifecycle in women

Mulheres estão sujeitas a um maior risco para o desenvolvimento de transtorno de estresse pós-traumático (TEPT) do que os homens, o que acarreta prejuízos e custos significativos do ponto de vista psicossocial e de saúde pública. Estudos recentes mostram interações complexas entre o impacto de experiências traumáticas e o ciclo reprodutivo feminino. Por exemplo, mulheres com transtorno disfórico pré-menstrual (TDPM), que também relatam histórico de trauma ou abuso físico, estão mais sujeitas a apresentar uma resposta neuroendócrina diferenciada após exposição a um fator ou evento estressante, quando comparadas a mulheres com TDPM e sem história de abuso ou mulheres sem TDPM. Além disso, mulheres com histórico de trauma ou abuso podem apresentar recidiva de sintomas durante a gravidez. Por fim, aquelas que sofrem abortamento estão mais sujeitas ao desenvolvimento de sintomas do transtorno de estresse pós-traumático. Neste artigo, examinamos os dados existentes sobre diferenças de gênero e transtorno de estresse pós-traumático, com enfoque especial nos fatores psicológicos e fisiológicos mais relevantes para o surgimento de sintomas após exposição a eventos traumáticos relacionados ao ciclo reprodutivo feminino. Opções terapêuticas existentes são criticamente revistas, incluído terapias de aconselhamento e a técnica de debriefing psicológico.
