Single-session visuospatial task procedure to prevent childbirth-related posttraumatic stress disorder: a multicentre double-blind randomised controlled trial.

Preventive evidence-based interventions for childbirth-related posttraumatic stress disorder (CB-PTSD) are lacking. Yet, 18.5% of women develop CB-PTSD symptoms following an unplanned caesarean section (UCS). This two-arm, multicentre, double-blind superiority trial tested the efficacy of an early single-session intervention including a visuospatial task on the prevention of maternal CB-PTSD symptoms. The intervention was delivered by trained maternity clinicians. Shortly after UCS, women were included if they gave birth to a live baby, provided consent, and perceived their childbirth as traumatic. Participants were randomly assigned to the intervention or attention-placebo group (allocation ratio 1:1). Assessments were done at birth, six weeks, and six months postpartum. Group differences in maternal CB-PTSD symptoms at six weeks (primary outcomes) and six months postpartum (secondary outcomes) were assessed with the self-report PTSD Checklist for DSM-5 (PCL-5) and by blinded research assessors with the Clinician-administered PTSD scale for DSM-5 (CAPS-5). Analysis was by intention-to-treat. The trial was prospectively registered (ClinicalTrials.gov, NCT03576586). Of the 2068 women assessed for eligibility, 166 were eligible and 146 were randomly assigned to the intervention (n = 74) or attention-placebo control group (n = 72). For the PCL-5, at six weeks, a marginally significant intervention effect was found on the total PCL-5 PTSD symptom count (ß = -0.43, S.E. = 0.23, z = -1.88, p < 0.06), and on the intrusions (ß = -0.73, S.E. = 0.38, z = -1.94, p < 0.0525) and arousal (ß = -0.55, S.E. = 0.29, z = -1.92, p < 0.0552) clusters. At six months, a significant intervention effect on the total PCL-5 PTSD symptom count (ß = -0.65, S.E. = 0.32, z = -2.04, p = 0.041, 95%CI[-1.27, -0.03]), on alterations in cognition and mood (ß = -0.85, S.E. = 0.27, z = -3.15, p = 0.0016) and arousal (ß = -0.56, S.E. = 0.26, z = -2.19, p < 0.0289, 95%CI[-1.07, -0.06]) clusters appeared. No group differences on the CAPS-5 emerged. Results provide evidence that this brief, single-session intervention carried out by trained clinicians can prevent the development of CB-PTSD symptoms up to six months postpartum.

The influence of the COVID-19 lockdown on infants' physiological regulation during mother-father-infant interactions in Switzerland.

In this study, we investigated the physiological regulation of vagal tone during dyadic and triadic parent-infant interactions in infants born before or around the COVID-19 lockdown in Switzerland. We hypothesized that there would be a decrease in vagal tone in triadic interactions compared with dyadic interactions, as triadic interactions are more complex and therefore more resource demanding. However, we expected this difference to be smaller for infants who experienced the period of confinement, as the lockdown led parents to spend more time at home. We also hypothesized that parents would have less stressful interactional events in the triadic interaction because they would be used to interacting with the child together. This study included 36 parents with their 3 month-old infants. Eighteen families met the study authors before the onset of the pandemic (pre-COVID) and 18 met them after its onset, having experienced a period of confinement during the infants' first 3 months of life (COVID). Results showed that the COVID group had no decrease in vagal tone during triadic interactions, whereas the pre-COVID group did. This difference could not, however, be explained by less stressful interactional events in triadic interactions, as the COVID group showed more stressful interactional events in mother-father-infant interactions.

Parental sensitivity, family alliance and infants' vagal tone: Influences of early family interactions on physiological emotion regulation.

In this study, we investigated the influence of parental sensitivity and family alliance on infants' vagal tone, considered as a physiological indicator of emotion regulation. Studies on mother-infant interactions have shown that vagal tone can be influenced by the quality of the interaction, such as interacting with a sensitive mother. To date, no study has investigated the influence of paternal sensitivity or family alliance on infants' vagal tone. We hypothesized that maternal sensitivity, paternal sensitivity, and family alliance would be associated with infants' vagal tone during dyadic and triadic interactions. We also explored if family alliance would act as a moderator on the association between parental sensitivity and vagal tone and if the sensitivity of both parents would act as a moderator on the association between family alliance and vagal tone. This study took place in Switzerland and included 82 families with their 3-4-month-old infants. Results showed that maternal sensitivity and family alliance were associated with infants' vagal tone, but paternal sensitivity was not. We found no significant moderation effect. However, result tendencies suggested that the contribution of paternal sensitivity to infants' emotion regulation could be influenced by family alliance, whereas maternal sensitivity and family alliance have a unique contribution.

En este estudio, investigamos la influencia de la sensibilidad del progenitor y la alianza de familia sobre el tono vagal del infante, considerado como un indicador fisiológico de regulación de la emoción. Los estudios acerca de las interacciones madre-infante han demostrado que el tono vagal puede ser influido por la calidad de la interacción, tal como el interactuar con una mamá sensible. Hasta hoy, ningún estudio ha investigado la influencia de la sensibilidad paterna o la alianza de familia sobre el tono vagal del infante. Nuestra hipótesis es que la sensibilidad materna, la sensibilidad paterna y la alianza de familia estaban asociadas con el tono vagal del infante durante las interacciones diádicas y triádicas. También exploramos si la alianza de familia actuaba como moderadora en la asociación entre la sensibilidad paterna y el tono vagal y si la sensibilidad de ambos progenitores actuaba como moderadora en la asociación entre la alianza de familia y el tono vagal. Este estudio se llevó a cabo en Suiza e incluyó a 82 familias con sus infantes de 3-4 meses de edad. Los resultados muestran que la sensibilidad materna y la alianza de familia estaban asociadas con el tono vagal del infante, pero que la sensibilidad paterna no lo estaba. No encontramos ningún efecto de moderación significativo. Sin embargo, las tendencias del resultado sugieren que la contribución de la sensibilidad paterna a la regulación de la emoción puede ser influida por la alianza de familia, mientras que la sensibilidad materna y la alianza de familia tienen una contribución particularmente única.

Dans cette étude nous nous sommes penchés sur l'influence de la sensibilité paternelle et de l'alliance de la famille sur le tonus vagal des nourrissons, considéré comme étant un indicateur physiologique de la régulation de l'émotion. Les études sur les interactions mère-nourrisson ont montré que le tonus vagal peut être influencé par la qualité de l'interaction, comme l'interaction avec une mère sensible. Jusqu'à présent aucune étude n'a porté sur l'influence de la sensibilité paternelle ou l'alliance familiale sur le tonus vagal des nourrissons. Nous avons fait l'hypothèse que la sensibilité maternelle, la sensibilité paternelle, et l'alliance familiale peuvent être liées au tonus vagal des nourrissons durant les interactions dyadiques et triadiques. Nous avons également exploré si l'alliance familiale pourrait agir comme modératrice sur le lien entre la sensibilité parentale et le tonus vagal et si la sensibilité des deux parents pourrait agir comme modérateur du lien entre l'alliance familiale et le tonus vagal. Cette étude s'est faite en Suisse et a inclus 82 familles avec des bébés de 3-4 mois. Les résultats ont montré que la sensibilité maternelle et l'alliance familiale étaient liées au tonus vagal des bébés mais la sensibilité de l'était pas. Nous n'avons trouvé aucun effet de modération important. Cependant les tendances des résultats ont suggéré que la contribution de la sensibilité paternelle à la régulation de l'émotion des nourrissons pourrait être influencée par l'alliance familiale alors que la sensibilité maternelle et l'alliance familiale a une contribution unique.

[Obstetrical anal sphincter injury†: How to manage the subsequent delivery†?] / Lésion obstétricale du sphincter anal†: comment aborder le prochain accouchement†?

Obstetric anal sphincter injury (OASI) is a complication of vaginal delivery. Its potential consequences are numerous and include anal and/or fecal incontinence, sexual problems and perineal pain, which can be aggravated by future pregnancies and childbirth. One common issue after OASI is the assessment of anorectal function to discuss the delivery modalities during the next pregnancy. This dedicated assessment includes a clinical and paraclinical evaluation, with an ultrasound and/or a manometry. This personalized assessment for each patient with a history of sphincter injury allows for a detailed discussion to decide on the route of delivery in an informed manner.

La lésion obstétricale du sphincter anal (LOSA) survient lors d'un accouchement vaginal. Ses conséquences potentielles sont l'incontinence anale et/ou fécale, les troubles sexuels et les douleurs périnéales, qui peuvent être aggravés par de futures grossesses et accouchements. Un des enjeux après LOSA est l'évaluation de la fonction anorectale dans le but de discuter les modalités d'accouchement lors de(s) prochaine(s) grossesse(s). Elle comprend une évaluation clinique et paraclinique spécialisée, incluant l'échographie et/ou la manométrie. Cette évaluation personnalisée pour chaque patiente avec antécédent de lésion sphinctérienne permet une discussion circonstanciée pour décider de la voie d'accouchement de manière éclairée.

A population pharmacokinetic model for escitalopram and its major metabolite in depressive patients during the perinatal period: Prediction of infant drug exposure through breast milk.

BACKGROUND AND OBJECTIVES: Escitalopram (SCIT) is frequently prescribed to breastfeeding women. Available information on SCIT excretion into breast milk is based on heterogeneous and incomplete data. A population pharmacokinetic model that aimed to better characterize maternal and infant exposure to SCIT and its metabolite was developed. METHODS: The study population was composed of women treated by SCIT or racemic citalopram and enrolled in the multicenter prospective cohort study SSRI-Breast Milk study (ClinicalTrial.gov NCT01796132). A joint structural model was first built for SCIT and S-desmethylcitalopram (SDCIT) in plasma using NONMEM and the milk-to-plasma ratio (MPR) was estimated by adding the drug breast milk concentrations. The effect of different influential covariates was tested and the average drug exposure with variability through breastfeeding was predicted under various conditions by simulation. RESULTS: The study enrolled 33 patients treated with SCIT or racemic citalopram who provided 80 blood and 104 milk samples. Mean MPR for both parent drug and metabolite was 1.9. Increased milk fat content was significantly associated with an increased drug transfer into breast milk (+28% for SCIT and +18% for SDCIT when fat amount doubles from 3.1 to 6.2 g/100 mL). Simulations suggested that an exclusively breastfed infant would ingest daily through breast milk 3.3% of the weight-adjusted maternal SCIT dose on average. CONCLUSION: The moderate between-subject variability in milk concentration of SCIT and the limited exposure to escitalopram through breast milk observed provide reassurance for treated mothers of breastfed healthy infants.

[State of knowledge of post-natal post-traumatic stress disorder]. / Etat des connaissances sur le trouble de stress post-traumatique du postpartum.

In this article, a synthesis of data from the literature on postpartum post-traumatic stress disorder (PTSD) related to childbirth is presented, knowing that the psychological suffering in this period of life is frequently associated with a certain taboo. The criteria to diagnose psychotraumatism, as well as postpartum PTSD just after the birth are here recalled as well as the importance of evaluating the subjective experience of the mother wich is a central issue. The clinical specificity and key symptoms of postpartum PTSD are described along with the risk and protective factors. In the light of scientific knowledge in the field of psychotraumatology, we present the prevention strategies of this disorder that can be applied, but which remain to be evaluated and tailored to this specific context.

Dans cet article, nous proposons une synthèse des données de la littérature sur le trouble de stress post-traumatique (TSPT) du postpartum en lien avec l'accouchement, en sachant que ce trouble continue d'être entouré d'un certain tabou. Les critères diagnostiques du psychotraumatisme, ainsi que du TSPT du postpartum (TSPTPP) en lien avec l'accouchement sont présentés. L'importance de l'évaluation du vécu subjectif de la mère est centrale. Les spécificités cliniques du TSPTPP en lien avec l'accouchement, à l'instar de la dépression du postpartum, sont présentées, de même que les facteurs de risque et de protection. A la lumière des connaissances scientifiques dans le champ de la psychotraumatologie, nous présentons les stratégies de prévention de ce trouble envisageables, mais qui restent à évaluer dans ce contexte spécifique.

[The placenta : a new target organ for hypertension ?] / Le placenta : nouvel organe cible de l'hypertension artérielle ?

The placenta has generated many beliefs over centuries and in all ethnicities. Considered in our society as a surgical waste, it is elsewhere contemplated for its mysterious protective powers, viewed as the seat of the soul, disposed of, burnt or even buried. However, once time is taken for its examination, the placenta tells a story. Of interest is the similarity observed between placental vascular disease in hypertensive pregnancy and atherosclerosis in coronary artery disease for example. Hypertension in pregnancy is frequent and associated with increased adverse obstetrical outcomes, and long-term risk of cardiovascular and kidney disease. This article will discuss the role of placental histopathology in hypertensive pregnancies, its indicative value for long-term cardiovascular risk in mothers and for subsequent pregnancy.

De tout temps, le placenta a fait l'objet de croyances. Simple déchet anatomique dans nos sociétés, il est ailleurs le siège de l'âme, brûlé, jeté, enterré. Pourtant, si l'on prend la peine de l'examiner, le placenta nous raconte une histoire. En effet, on observe un mimétisme entre les atteintes artérielles placentaires des grossesses hypertensives et les lésions d'artériosclérose de la coronaropathie par exemple. Les grossesses hypertensives sont fréquentes, associées à court terme à un risque accru de complications obstétricales, et à long terme de maladies cardiovasculaires et rénales. Cet article se propose de discuter l'utilité de l'examen du placenta en cas d'hypertension, de sa valeur indicative sur la survenue d'événements cardiovasculaires à long terme chez la mère, et du risque sur le déroulement d'une grossesse ultérieure.

[SSRI antidepressant use during pregnancy and the assessment of the risk-benefit ratio]. / Bon usage des antidépresseurs ISRS durant la grossesse--le défi de l'évaluation de la balance bénéfice-risque.

Studies report that between 6 and 13% of women experience symptoms of depression during pregnancy and the postpartum period. The abundant data available make selective serotonin reuptake inhibitors (SSRIs) the first line treatment in pregnancy when a pharmacological treatment is required. Risks associated with the use of SSRIs during pregnancy are limited (moderate effect size) and are often not distinguishable from those inherent to the mother's disease. Yet, several questions regarding the SSRI safety profile for the unborn child are still under debate or require additional epidemiological data. The decision of SSRI use during pregnancy needs an individual evaluation of the risk-benefit balance.

[The art of being when there is nothing you can do: caring for perinatal bereavement]. / Etre là quand on ne peut rien faire: accompagnement du deuil périnatal.

The period of mourning after perinatal loss is not synonym for depression. The article illustrates a way of caring for bereaved parents, which takes into account the temporality and individual nature of the bereavement process. The use of rituals and symbolic gestures allows for calling into existence the loss of a human being, who is gone without leaving many reminders. Psychotherapeutic care by the liaison-psychiatric service is part of the multidisciplinary care program proposed by the maternity of the University Hospitals of Geneva. These encounters offer parents the possibility to continue to include the dead in the membership of our lives.

The Maternal Psychic Impact of Infection by SARS-CoV-2 during Pregnancy: Results from a Preliminary Prospective Study.

Due to a higher risk of maternal complications during pregnancy, as well as pregnancy complications such as stillbirth, SARS-CoV-2 contamination during pregnancy is a putative stress factor that could increase the risk of perinatal maternal mental health issues. We included women older than 18 years, who delivered a living baby at the Geneva University Hospitals' maternity wards after 29 weeks of amenorrhea (w.a.) and excluded women who did not read or speak fluent French. We compared women who declared having had COVID-19, confirmed by a positive PCR test for SARS-CoV-2, during pregnancy with women who did not, both at delivery and at one month postpartum. We collected clinical data by auto-questionnaires between time of childbirth and the third day postpartum regarding the occurrence of perinatal depression, peritraumatic dissociation, and peritraumatic distress during childbirth, measured, respectively, by the EPDS (depression is score > 11), PDI (peritraumatic distress is score > 15), and PDEQ (scales). At one month postpartum, we compared the proportion of women with a diagnosis of postpartum depression (PPD) and birth-related posttraumatic stress disorder (CB-PTSD), using PCL-5 for CB-PTSD and using diagnosis criteria according DSM-5 for both PPD and CB-PTSD, in the context of a semi-structured interview, conducted by a clinician psychologist. Off the 257 women included, who delivered at the University Hospitals of Geneva between 25 January 2021 and 10 March 2022, 41 (16.1%) declared they had a positive PCR test for SARS-CoV-2 during their pregnancy. Regarding mental outcomes, except birth-related PTSD, all scores provided higher mean values in the group of women who declared having been infected by SARS-CoV-2, at delivery and at one month postpartum, without reaching any statistical significance: respectively, 7.8 (±5.2, 8:4-10.5) versus 6.5 (±4.7, 6:3-9), p = 0.139 ***, for continuous EPDS scores; 10 (25.0) versus 45 (21.1), p = 0.586 *, for dichotomous EPDS scores (≥11); 118 (55.7) versus 26 (63.4), p = 0.359 *, for continuous PDI scores; 18.3 (±6.8, 16:14-21) versus 21.1 (±10.7, 17:15-22), 0.231 ***, for dichotomous PDI scores (≥15); 14.7 (±5.9, 13:10-16) versus 15.7 (±7.1, 14:10-18), p = 0.636 ***, for continuous PDEQ scores; 64 (30.0) versus 17 (41.5), p = 0.151 *, for dichotomous PDEQ scores (≥15); and 2 (8.0) versus 5 (3.6), p = 0.289 *, for postpartum depression diagnosis, according DSM-5. We performed Chi-squared or Fisher's exact tests, depending on applicability for the comparison of categorical variables and Mann-Whitney nonparametric tests for continuous variables; p < 0.05 was considered as statistically significant. Surprisingly, we did not find more birth-related PTSD as noted by the PCL-5 score at one month postpartum in women who declared a positive PCR test for SARS-CoV-2:15 (10.6) versus no case of birth related PTSD in women who were infected during pregnancy (p = 0.131 *). Our study showed that mental outcomes were differently distributed between women who declared having been infected by SARS-CoV-2 compared to women who were not infected. However, our study was underpowered to explore all the factors associated with psychiatric issues during pregnancy, postpartum, depending on the exposure to SARS-CoV-2 infection during pregnancy. Future longitudinal studies on bigger samples and more diverse populations over a longer period are needed to explore the long-term psychic impact on women who had COVID-19 during pregnancy.

The Interplay Between Maternal and Paternal Senses of Efficacy Moderates the Link Between Perinatal Parental Stress and Family Alliance at 3 Months.

Objective. Both parents may report high levels of stress during the perinatal period with possible negative consequences for parental well-being and child development. Parental sense of efficacy moderates the effect of stress. To date, no studies have assessed links between parental stress and mother-father-infant interactions in terms of family alliance and the extent to which each parent's sense of efficacy moderates these links. Design. In this study, 65 dual-parent families answered a questionnaire about parental stress between 36 and 38 weeks of pregnancy and at 3 months after birth. Families were also observed while playing with their 3-month-old infant in the Lausanne Trilogue Play, and they completed a questionnaire about parental efficacy. Results. Structural equation modeling analyses showed that higher maternal or paternal postnatal stress has a direct link with higher family alliance and the links between stress and family alliance are moderated by complex interaction effects between maternal and paternal senses of efficacy. Conclusions. This study shows the necessity of considering the interaction between the senses of self-efficacy of both parents as moderators of parenting stress.

Perinatal arterial ischemic stroke: how informative is the placenta?

Neuroplacentology is an expanding field of interest that addresses the placental influence on fetal and neonatal brain lesions and on further neurodevelopment. The objective of this study was to clarify the link between placental pathology and perinatal arterial ischemic stroke (PAIS). Prior publications have reported different types of perinatal stroke with diverse methodologies precluding firm conclusions. We report here the histological placental findings in a series of 16 neonates with radiologically confirmed PAIS. Findings were grouped into 3 categories of lesions: (1) inflammation, (2) placental and fetal hypoxic lesions, and (3) placentas with a high birthweight/placenta weight ratio. Matched control placentas were compared to the pathological placentas when feasible. The eight term singleton placentas were compared to a series of 20 placentas from a highly controlled amniotic membrane donation program; in three twin pregnancies, the placental portions from the affected twin and unaffected co-twin were compared. Slightly more than half (9/16, 56%) had histopathological features belonging to more than one category, a feature shared by the singleton control placentas (13/20, 65%). More severe and extensive lesions were however observed in the pathological placentas. One case occurring in the context of SARS-CoV-2 placentitis further expands the spectrum of COVID-related perinatal disease. Our study supports the assumption that PAIS can result from various combinations and interplay of maternal and fetal factors and confirms the value of placenta examination. Yet, placental findings must be interpreted with caution given their prevalence in well-designed controls.

Interactive synchrony and infants' vagal tone as an index of emotion regulation: associations within each mother- and father-infant dyad and across dyads.

Introduction: Studies have shown that infants' emotion regulation capacities are closely linked to the quality of parent-infant interactions. However, these links have been mostly studied in mother-infant dyads and less is known about how the quality of father-infant interactions contributes to the development of emotion regulation during infancy. In this study, we aimed to investigate the links between interactive synchrony (i.e., an index of the quality of parent-infant coordination of interactive behaviors) and infants' vagal tone (i.e., a physiological index of emotion regulation). To understand the respective contributions of both parents, as well as the interrelations between the functioning of both dyads within a family, we observed mothers and fathers from 84 families interacting with their infants. Methods: Synchrony was assessed by using the CARE-Index; infants' vagal tone was derived from the analysis of infants' electrocardiograms recorded during the interactions. Moreover, to take the play's order into account, we counterbalanced the procedure, so that approximately half of the mothers played first. We specified a first structural equation modeling (SEM) model to investigate the associations between interactive synchrony and the infants' root mean square of successive differences (RMSSD), an index of vagal regulation, in the two successive parts of the play. We conducted a multigroup analysis in a second SEM model to investigate the associations of the first SEM model in two groups based on the order of interaction. Results: The results of the SEM models showed that greater synchrony was related to greater infant RMSSD within mother-infant dyads and across one dyad to the other dyad in the full sample and in the group of fathers who interacted first with the infants. The associations between synchrony and infant vagal tone within father-infant dyads never appeared to be significant, nor did any associations within each dyad and across dyads when mothers interacted first. Discussion: This study highlights that the links between interactions and infants' vagal tone are sensitive to family members' interdependencies and some conditions (the order of interaction).

Infant exposure to Fluvoxamine through placenta and human milk: a case series - A contribution from the ConcePTION project.

Introduction: Fluvoxamine is widely used to treat depression during pregnancy and lactation. However, limited data are available on its transfer to the fetus or in human milk. This case series provides additional information on the infant exposure to fluvoxamine during pregnancy and lactation. Case presentation: Two women, aged 38 and 34 years, diagnosed with depression were treated with 50 mg fluvoxamine during pregnancy and lactation. At delivery a paired maternal and cord blood sample was collected for each woman. The first mother exclusively breastfed her child for 4 months and gave one foremilk and one hindmilk sample at 2 days and 4 weeks post-partum, whereas the second mother did not breastfeed. Results: The cord to plasma concentration ratios were 0.62 and 0.48, respectively. At 2 weeks post-partum, relative infant doses (RID) were 0.47 and 0.57% based on fluvoxamine concentrations in foremilk and hindmilk, respectively. At 4 weeks post-partum, the RIDs were 0.35 and 0.90%, respectively. The child from the first mother was born healthy and showed a normal development at the 6th, 18th and 36th month follow-ups. One of the twins from the second woman was hospitalized for hypoglycemia that was attributed to gestational diabetes and low birth weight. The second one was born healthy. Conclusion: These results suggest a minimal exposure to fluvoxamine during lactation which is in accordance with previously published data. Larger clinical and pharmacokinetic studies assessing the long-term safety of this drug during lactation and the variability of its exposure through breastmilk are warranted.

Expression of metalloproteinases 1, 2, 7, 9, and 12 in human cytotrophoblastic cells from normal and preeclamptic placentas.

OBJECTIVES: Preeclampsia is a specific pregnancy disorder which could be due, at least in part, to impaired invasion of trophoblastic cells. Since matrix metalloproteinases (MMPs) are the predominant proteases involved in trophoblastic invasion, we investigated and compared expression of MMP-1, 2, 7, 9 and 12 of cytotrophoblastic cells (CTB) purified from preeclamptic (PE) placentas to control CTB. MATERIAL AND METHODS: In order to evaluate invasive properties of cells, purified CTB were seeded on collagen-coated insert following boyden chamber principle and matrix metalloproteinases (MMPs) expression was evaluated by qPCR. RESULTS: Our results showed that PE CTB are less invasive than control CTB in vitro. In parallel, expression of MMPs, except for MMP-2, tends to be decreased in PE CTB compared to control CTB. CONCLUSION: At the exception of MMP-2, this study confirms the importance of MMPs in development of PE.

Traumatic Childbirth and Birth-Related Post-Traumatic Stress Disorder in the Time of the COVID-19 Pandemic: A Prospective Cohort Study.

BACKGROUND: Birth-related post-traumatic stress disorder occurs in 4.7% of mothers. No previous study focusing precisely on the stress factors related to the COVID-19 pandemic regarding this important public mental health issue has been conducted. However, the stress load brought about by the COVID-19 pandemic could have influenced this risk. METHODS: We aimed to estimate the prevalence of traumatic childbirth and birth-related PTSD and to analyze the risk and protective factors involved, including the risk factors related to the COVID-19 pandemic. We conducted a prospective cohort study of women who delivered at the University Hospitals of Geneva between 25 January 2021 and 10 March 2022 with an assessment within 3 days of delivery and a clinical interview at one month post-partum. RESULTS: Among the 254 participants included, 35 (21.1%, 95% CI: 15.1-28.1%) experienced a traumatic childbirth and 15 (9.1%, 95% CI: 5.2-14.6%) developed a birth-related PTSD at one month post-partum according to DSM-5. Known risk factors of birth-related PTSD such as antenatal depression, previous traumatic events, neonatal complications, peritraumatic distress and peritraumatic dissociation were confirmed. Among the factors related to COVID-19, only limited access to prenatal care increased the risk of birth-related PTSD. CONCLUSIONS: This study highlights the challenges of early mental health screening during the maternity stay when seeking to provide an early intervention and reduce the risk of developing birth-related PTSD. We found a modest influence of stress factors directly related to the COVID-19 pandemic on this risk.

[Management of thrombocytopenia during pregnancy]. / Prise en charge des thrombopénies au cours de la grossesse.

Thrombocytopenia defined as a platelet count < 150 G/l is found in about 10% of pregnancies. The differential diagnosis is similar to that of non-pregnant women but some specific causes related to pregnancy need to be considered. Even if the so-called gestational thrombocytopenia is the most common etiology, a careful history and simple laboratory tests are needed in order not to miss a serious condition that may require specific and sometimes urgent treatment. However in most cases detailed investigations are not required during pregnancy and a pragmatic attitude can be proposed, including monitoring of platelet count in the mother and platelet count in the newborn.

The fine-tuning of endoplasmic reticulum stress response and autophagy activation during trophoblast syncytialization.

The syncytiotrophoblast (STB) is a multinuclear layer forming the outer surface of the fetal part of the placenta deriving from villous cytotrophoblastic cell (vCTB) fusion and differentiation. This syncytialization process is characterized by morphological and biochemical alterations of the trophoblast, which probably require removal of pre-existing structures and proteins to maintain cell homeostasis and survival. Interestingly, autophagy, which allows degradation and recycling of cellular components, was shown to be activated in syncytiotrophoblast. Here we examined the involvement of endoplasmic reticulum stress (ERS) response in autophagy activation during vCTB syncytialization. We first demonstrated the activation of ERS response and autophagy during the time course of trophoblastic cell fusion and differentiation. Alteration of autophagy activation in vCTB by chemical treatments or Beclin-1 expression modulation leads to a decrease in trophoblastic syncytialization. Furthermore, ERS response inhibition by chemical treatment or siRNA strategy leads to a default in syncytialization, associated with alteration of autophagy markers and cell survival. From these data, we suggest that ERS response, by fine regulation of autophagy activation, may serve as an adaptive mechanism to promote cell survival during trophoblastic syncytialization.

Risk-benefit balance assessment of SSRI antidepressant use during pregnancy and lactation based on best available evidence - an update.

Introduction: Depression affects 300 million individuals worldwide. While selective serotonin reuptake inhibitors (SSRI) are one of the first-line pharmacological treatments of major depression in the general population, there is still uncertainty regarding their potential benefits and risks during pregnancy. Areas covered: Outcomes requisite for a proper risk/benefit assessment of SSRI in pregnancy and lactation were considered: (a) potential risks associated with untreated depression, (b) effectiveness of different treatment options of depression, (c) potential risks associated with SSRI. Expert opinion: Despite the growing amount of literature on SSRI use during pregnancy, no new trials assessing the benefits of SSRIs on maternal depression were found. In the light of new data regarding the potential risks, depressed SSRI-treated pregnant women and their children seem at increased risk for several complications (mostly of small absolute risk). The interpretation of these findings remains quite similar to our previous review as the available methodology does not allow to disentangle the potential effect of SSRIs from those of the disease itself or/and of its unmeasured associated risk factors. Thus, in pregnant or lactating women who require a pharmacological treatment, SSRIs can still be considered as appropriate when effective as the abundant data support their relative safety.
