Exploring perceptions of vulnerability among women facing psychosocial adversity before, during and after pregnancy: A qualitative interview-study using thematic analysis.

OBJECTIVE: The term 'vulnerable' is often used to describe women facing psychosocial adversity during pregnancy, implying a heightened risk of experiencing suboptimal pregnancy outcomes. While this label might facilitate the pathway to appropriate care, it can be perceived as stigmatizing by the women it intends to help, which could deter their interaction with healthcare services. This study explores how women facing psychosocial adversity before, during and after pregnancy perceive the concept of vulnerability and experience being labeled as such. METHODS: We conducted a thematic analysis of semi-structured, in-depth interviews. Through purposive sampling targeting maximum variation, ten women of diverse backgrounds were included. RESULTS: Three central themes emerged: defining vulnerability, embracing vulnerability and the feeling of being stigmatized. Women perceived vulnerability as an inability to adequately care for themselves or their children, necessitating additional support alongside routine antenatal care. Acceptance of the 'vulnerable' label came when it also acknowledged their proactive efforts and strengths to improve their situation. Conversely, if discussions surrounding vulnerability failed to recognize women's agency - specifically, their personal journeys and the courage needed to seek support - the label was perceived as stigmatizing. CONCLUSIONS: Addressing vulnerability effectively in maternity care requires a nuanced, patient-centered approach, acknowledging both the challenges and strengths of women facing psychosocial adversities. Emphasizing personal narratives and their courage in seeking support can mitigate the stigmatizing effects of the 'vulnerable' label. Integrating these narratives into maternal healthcare practices can foster deeper connections with the women involved, enhancing the overall quality of care.

Early-life malnutrition role in memory, emotional behavior and motor impairments in early brain lesions with potential for neurodevelopmental disorders: a systematic review with meta-analysis.

OBJECTIVES: The present study aims to evaluate the impact of early exposure to brain injury and malnutrition on episodic memory and behavior. METHODS: For this, a systematic review was carried out in the Medline/Pubmed, Web of Science, Scopus, and LILACS databases with no year or language restrictions. RESULTS: Initially, 1759 studies were detected. After screening, 53 studies remained to be read in full. The meta-analysis demonstrated that exposure to double insults worsens episodic recognition memory but does not affect spatial memory. Early exposure to low-protein diets has been demonstrated to aggravate locomotor and masticatory sequelae. Furthermore, it reduces the weight of the soleus muscle and the muscle fibers of the masseter and digastric muscles. Early exposure to high-fat diets promotes an increase in oxidative stress and inflammation in the brain, increasing anxiety- and depression-like behavior and reducing locomotion. DISCUSSION: Epigenetic modifications were noted in the hippocampus, hypothalamus, and prefrontal cortex depending on the type of dietetic exposure in early life. These findings demonstrate the impact of the double insult on regions involved in cognitive and behavioral processes. Additional studies are essential to understand the real impact of the double insults in the critical period.

Amenable Mortality in Children under 5: An Indicator for Identifying Inequalities in Healthcare Delivery: A Review.

Universal health coverage has been proposed as a strategy to improve health in low- and middle-income countries, but this depends on a good provision of health services. Under-5 mortality (U5M) reflects the quality of health services, and its reduction has been a milestone in modern society, reducing global mortality rates by more than two-thirds between 1990 and 2020. However, despite these impressive achievements, they are still insufficient, and most deaths in children under 5 can be prevented with the provision of timely and high-quality health services. The aim of this paper is to conduct a literature review on amenable (treatable) mortality in children under 5. This indicator is based on the concept that deaths from certain causes should not occur in the presence of timely and effective medical care. A systematic and exhaustive review of available literature on amenable mortality in children under 5 was conducted using MEDLINE/PubMed, Cochrane CENTRAL, OVID medline, Scielo, Epistemonikos, ScienceDirect, and Google Scholar in both English and Spanish. Both primary sources, such as scientific articles, and secondary sources, such as bibliographic indices, websites, and databases, were used. Results: The main cause of amenable mortality in children under 5 was respiratory disease, and the highest proportion of deaths occurred in the perinatal period. Approximately 65% of avoidable deaths in children under 5 were due to amenable mortality, that is, due to insufficient quality in the provision of health services. Most deaths in all countries and around the world are preventable, primarily through effective and timely access to healthcare (amenable mortality) and the management of public health programs focused on mothers and children (preventable mortality).

Oscillating autonomy: a grounded theory study of women's experiences of COVID-19 infection during pregnancy, labour and birth, and the early postnatal period.

BACKGROUND: Testing positive for COVID-19 was associated with higher rates of detrimental psycho-social and physical health outcomes. The COVID-19 pandemic caused unprecedented disruption to everyday life. This included major reconfiguration of maternal, child, and perinatal mental health and care services and provision. This study aimed to investigate the experiences of those who tested positive for COVID-19 during pregnancy, labour and birth, or the early postnatal period. METHODS: National on-line recruitment from across the United Kingdom resulted in sixteen mothers being invited to qualitative semi-structured interviews to understand the experiences of mothers who had been infected by COVID-19 during pregnancy, labour and birth, or the early postnatal period. Interviews were conducted, recorded, and transcribed using video-conferencing software. A Grounded Theory approach was used to analyse the data gathered pertaining to women's experiences of their positive COVID-19 diagnosis during pregnancy, labour and birth, or the early postnatal period. RESULTS: The theory of 'Oscillating Autonomy - Losing and Seeking to Regain Control by Striving for Agency' was developed, comprising three main themes: 'Anxious Anticipation: The fear of infection was worse than COVID-19 itself'; 'Fluctuating Agency: What changed when COVID-19 took control'; and 'Reclaiming Control: Seeking reassurance during COVID-19 positivity'. Testing positive for COVID-19 whilst pregnant, during labour or birth, or in the early postnatal period was associated with a perceived loss of control. Those who were able to regain that control felt more secure in their situation. CONCLUSIONS: Support was paramount to manage increased vulnerability, as was reassurance achieved by information seeking and positive action including increased health monitoring and COVID-19 vaccination.

PERINATAL CARDIAC FUNCTIONAL ADAPTATION IN HYPOPLASTIC LEFT HEART SYNDROME: A LONGITUDINAL ANALYSIS.

BACKGROUND: The perinatal transition is characterized by acute changes in cardiac loading. Compared to normal newborn combined cardiac output (CCO), single right ventricular (RV) output of neonates with hypoplastic left heart syndrome (HLHS) is markedly greater. We sought to examine the mechanisms of cardiac adaptation which facilitate this perinatal transition from late fetal to early neonatal life in HLHS. METHODS: Prospectively recruited pregnancies complicated by fetal HLHS (n=35) and health controls (Ctrl, n=17) underwent serial echocardiography in late gestation (38±1weeks) and 6, 24 and 48 hours after birth. Cardiac function was assessed using conventional, tissue Doppler and speckle tracking echocardiography. RESULTS: Term HLHS fetuses had an RV output (RVCO) comparable to Ctrl CCO via higher stroke volume (SV). Compared to both left ventricular (LV) and RV indices of Ctrls, they exhibited a globular and dilated RV with reduced relative wall thickness (RWT) [RWT: 0.40±0.08 vs. 0.49±0.10, p<0.01], increased Tei index' [HLHS vs. Ctrl LV/Ctrl RV: sphericity index (SI): 0.9±0.25 vs. 0.5±0.10/0.6±0.11, RV area index: 28±6cm2/m2 vs. 15±3cm2/m2/17±5cm2/m2, Tei index': 0.65±0.11 vs. 0.43±0.07/0.45±0.09, all p<0.0001]. HLHS neonates generated elevated RVCO compared to Ctrl CCO via higher heart rate and SV, with further RV dilatation, increased longitudinal systolic strain at 48h [-17±4% vs. -14±3%/-14±5%] with reduced circumferential and rotational myocardial deformation and altered diastolic function. HLHS neonates also demonstrated right atrial (RA) enlargement with increased longitudinal strain: 6h (33±12% vs. 26±6%), 24h (37±15% vs. 26±13%), 48h (38±11% vs. 24±13%), p<0.0001. CONCLUSIONS: Term HLHS fetuses exhibit altered RV geometry and RV systolic and diastolic functional parameters. After birth, further alterations in these cardiac parameters likely reflect adaptation to acutely altered RV loading from increasing cardiac output and pulmonary artery flow demands.

Perinatal Economic Abuse: Experiences, Impacts, and Needed Resources.

Introduction: Economic abuse is one form of intimate partner violence (IPV) intended to control a survivor's ability to make, save, or spend money to gain power over them. Perinatal people may be more vulnerable to economic abuse due to changes in employment and finances. This study's aims were to explore how economic abuse manifests among pregnant and parenting survivors and how best to support pregnant and parenting survivors of economic abuse. Methods: We conducted virtual semistructured interviews with IPV survivors and IPV advocates. Participants were recruited through an online recruitment registry, national IPV organizations, and local domestic violence agencies. Interview audiorecordings were transcribed. We used a deductive-inductive thematic analysis approach. Two research team members individually coded each transcript and met to resolve discrepancies in coding. Results: We completed interviews with 18 advocates and 20 survivors. Participants described experiences of financial control, exploitation, and employment sabotage. Partners leveraged the criminal-legal, child welfare, and health care systems and cultural norms about pregnancy, including those related to gender and religion to financially harm survivors. Advocates described how economic abuse impacts marginalized survivors. Dream resources described include cash assistance, healthy relationship and financial education, and employer policies. Discussion: Survivors and advocates reported a variety of experiences with economic abuse during the perinatal period. Future interventions should focus on providing unrestricted cash transfers to survivors, developing education on economic abuse, and creating supportive policies in health care and employment settings. This study highlights the ways that economic abuse specifically impacts perinatal survivors and their children.

No sex difference in maturation of brain morphology during the perinatal period.

Accumulating evidence have documented sex differences in brain anatomy from early childhood to late adulthood. However, whether sex difference of brain structure emerges in the neonatal brain and how sex modulates the development of cortical morphology during the perinatal stage remains unclear. Here, we utilized T2-weighted MRI from the Developing Human Connectome Project (dHCP) database, consisting of 41 male and 40 female neonates born between 35 and 43 postmenstrual weeks (PMW). Neonates of each sex were arranged in a continuous ascending order of age to capture the progressive changes in cortical thickness and curvature throughout the developmental continuum. The maturational covariance network (MCN) was defined as the coupled developmental fluctuations of morphology measures between cortical regions. We constructed MCNs based on the two features, respectively, to illustrate their developmental interdependencies, and then compared the network topology between sexes. Our results showed that cortical structural development exhibited a localized pattern in both males and females, with no significant sex differences in the developmental trajectory of cortical morphology, overall organization, nodal importance, and modular structure of the MCN. Furthermore, by merging male and female neonates into a unified cohort, we identified evident dependencies influences in structural development between different brain modules using the Granger causality analysis (GCA), emanating from high-order regions toward primary cortices. Our findings demonstrate that the maturational pattern of cortical morphology may not differ between sexes during the perinatal period, and provide evidence for the developmental causality among cortical structures in perinatal brains.

The physical experiences of women with lower limb absence during pregnancy and postpartum: symptoms, prosthesis management & mobility.

PURPOSE: Little information is available to women with lower limb absence (LLA) and their health care providers regarding the impacts they may experience during the perinatal period. This study explores the physical impacts of pregnancy on women with LLA, including mobility, prosthesis fit and prosthesis use. METHODS: We conducted semi-structured interviews with 19 women with LLA who had experienced pregnancy in the last 10 years. Interviews were analyzed using thematic analysis. RESULTS: Substantial variation exists in the experience of women's physical symptoms, prosthesis management and mobility. Physical symptoms were similar to any pregnant individual, but the impacts were more substantial. As volume change in the residual limb can impact prosthesis fit, self-management techniques and prosthetist adjustments were used to manage it. Pregnancy impacted the way in which women were mobile and the activities they chose to participate in. A wide variety of creative mobility solutions were utilized to complete activities including prosthesis use, assistive equipment and adaptive movement. CONCLUSIONS: Women with LLA and their health care providers must be aware of the wide range of experiences women face during pregnancy and treat each pregnancy uniquely. Planning ahead and working with a health care team can mitigate many of these challenges.

Rumen microbiota succession throughout the perinatal period and its association with postpartum production traits in dairy cows: A review.

The transition period for dairy cows usually refers to the 3 weeks pre-calving to the 3 weeks post-calving. During this period, dairy cows undergo metabolic and physiological adaptations because of their susceptibility to metabolic and infectious diseases. Poor feeding management under these circumstances may adversely affect the health and subsequent production performance of the cows. Owing to long-term adaptation and evolution, the rumen has become a unique ecosystem inhabited by a complex microbial community closely associated with its natural host. Dietary components are metabolized by the rumen microbiota, and volatile fatty acids and microbial protein products can be used as precursor substances for synthesizing meat and milk components. The successful transition of perinatal dairy cows includes changes in diet, physiology, and the rumen microbiota. Rumen microbial profiles have been confirmed to be heritable and repairable; however, adverse circumstances affect rumen microbial composition, host digestion and metabolism, as well as postpartum production traits of dairy cows for a certain period. Preliminary evidence indicates a close relationship between the rumen microbiota and animal performance. Therefore, changes in rumen microbes during the transition period and the intrinsic links between the microbiota and host postpartum phenotypic traits need to be better understood to optimize production performance in ruminants.

Effects of depression and stress on oral self-care among perinatal women in Appalachia: A longitudinal study.

OBJECTIVES: Oral health during the perinatal period and beyond affects the health and well-being of women and their offspring. Oral self-care behaviours can maintain or improve oral health; depression or stress during the perinatal period may compromise these behaviours. The aim of the study was to investigate the independent and combined effects of depression and stress on oral self-care behaviours of perinatal women in Appalachia, given the high burden of oral disease in this region. METHODS: A total of 1172 women in the first or second trimester of pregnancy were enrolled in the Center for Oral Health Research in Appalachia, cohort 2 (COHRA2) in West Virginia or Pittsburgh, Pennsylvania. Participants completed the Center for Epidemiological Studies Depression Scale, Perceived Stress Scale-10, and self-report items about oral self-care behaviours (i.e. toothbrushing and flossing) during pregnancy and five times in the 2+ years following birth. A Generalized Estimating Equation approach was used to analyse the longitudinal data. RESULTS: Maternal depression and stress were independently negatively related to toothbrushing and flossing frequency. These findings for toothbrushing were more pronounced in those with high levels of depression and high levels of stress, so there were both independent and combined effects. Frequency of toothbrushing and flossing stayed constant over time, so time was not associated with outcomes. About three-fourths of the sample reported toothbrushing levels that are consistent with established guidelines (i.e. two times daily), but almost half of the participants had very low levels of flossing (i.e. once or less a week). CONCLUSION: Interventions targeting stress and depression throughout the perinatal period might be helpful in improving oral self-care behaviours and oral health among women in Appalachia, in addition to the benefit of decreasing emotional distress.

Perinatal mental disorders and suicidal risk among adolescent mothers living in urban areas of Cameroon.

Background: In sub-Saharan Africa the birth rate among teenage mothers is the highest in the world. In 2021, there would be 6,114,000 births for 15-19-year-olds in this part of the world. In Cameroon, the fertility rate among adolescents aged 15-19 is 24%. However, there is a significant lack of data on the mental health of teenage mothers. Given the biopsychosocial conditions of the perinatal period and adolescence, we hypothesise that the prevalence of mental disorders and the risk of suicide is very high in Cameroon. The aim is therefore to determine the prevalence of perinatal mental disorders and suicide risk among adolescent mothers in urban areas of Cameroon. Methods: Following ethical approval of the submitted protocol, we recruited adolescent mothers and data were collected using diagnostic interviews based on the DSM-5, PDM-2 and MINI guidelines. The types of sampling used were typical and incidental. Data were tabulated with Epidata 3.1 and processed with SPSS 25. Results: 66.4% of adolescent mothers were diagnosed with a mental disorder and 27.4% with suicidal risk. It was found that there was a link between mental disorders and suicidal risk (p<0.001), with mothers at suicidal risk having an 8.4 times greater risk of having a mental disorder (OR=8.423). Linear regression confirmed the statistically significant relationship between perinatal mental disorders and suicidal risk. 31.1% of the total variance in suicidal risk was explained by mental disorders. The regression coefficients for mental disorders with a p<0.05 value is: perinatal depression (-0.279), post-partum psychosis (-0.133), trauma disorder (-0.034), generalised anxiety disorder (-0.008) and conduct disorder (-0.020). Conclusions: Our hypothesis is confirmed, because the prevalence of 66.4% of mental disorders and 27.4% of suicidal risk are significantly high in Cameroon. In some way, the disorders predict suicidal risk, because the less an adolescent mother has one of these pathologies during the perinatal period, the less she will be at risk of suicide. More research of this kind is needed to contribute in providing more data, including solutions to address the morbidity and mortality problems associated with the mental health of teenage mothers.

Depression in the Perinatal Period: Course and Outcome of Depression in the Period from the Last Trimester of Pregnancy to One Year after Delivery in Primiparous Mothers.

Background and Objectives: One of the most significant psychiatric problems in women is depression related to the perinatal period. Our study aims to determine the frequency and course of depressive symptomatology in the perinatal period with particular reference to objective rate and outcome of postpartum depression. Materials and Methods: One hundred and eighty-eight pregnant/postnatal women were included in a prospective, longitudinal, observational study during which the depressive symptomatology was estimated at the third trimester of pregnancy, and the first, sixth, and twelfth month' postpartum. All participants completed a semi-structured sociodemographic questionnaire constructed for research purposes, the Edinburgh Postnatal Depression Scale, Toronto Alexithymia Scale, Beck Anxiety Inventory, and The Mood Disorder Questionnaire at each time point. Postpartum depression diagnosis was confirmed by a trained and certified psychiatrist with long-standing experience. For a better understanding of the trajectory of depressive symptomatology and genuine postpartum depression, we classified depression into those with new-onset and those left over from the previous observation period. Results: In general, 48.9% of participants in the study were depressed at some point during the investigation. A total of 10.6% of women were depressed in the third trimester. The highest percentage of new-onset depression (25%) was in the first month after giving birth and was maintained for up to six months, after which the appearance was sporadic. Most of the postpartum depression resolved in the period from the first month to the sixth month after childbirth (20.7%). The episodes mainly had characteristics of unipolar depression. Conclusions: Our results imply that a new onset of depression is most intensive during the first six months, and after that, it is sporadic. Further studies are needed to explore whether all depressive symptomatology in the postnatal period is the same, or perhaps postpartum depression, classified in this way, has specific characteristics, etiology, and consequently different treatment and preventive options.

Effect of Bright Light Therapy on Perinatal Depression: A Systematic Review and Meta-Analysis: Effet de la luminothérapie sur la dépression périnatale: une revue systématique et une méta-analyse.

OBJECTIVE: This study represents the inaugural attempt to systematically review and analyse the efficacy of bright light therapy on depression among women experiencing major depressive disorder or depressive symptoms during the perinatal period, encompassing its efficacy on depression scores, remission rates, and response rates. METHODS: We searched 10 databases for randomized controlled trials examining bright light therapy's efficacy on perinatal depression up to January 2024. Data extraction was performed independently by 2 investigators. The Cochrane Handbook guidelines appraised the study quality, and the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) approach assessed evidence certainty. RESULTS: We incorporated 6 studies, encompassing 151 participants. When contrasted with dim light therapy, bright light therapy did not significantly alter depression scores (standard mean difference = -0.29, 95% confidence interval [CI], -0.62 to 0.04, P = 0.08, I² = 34%) or response rates (risk ratio [RR] = 1.56, 95% CI, 0.98 to 2.49, P = 0.06, I² = 0%) in women experiencing perinatal depression. Conversely, bright light therapy was associated with a substantial increase in remission rates (RR = 2.63, 95% CI, 1.29 to 5.38, P = 0.008, I² = 2%). CONCLUSION: Bright light therapy did not show efficacy in treating perinatal depression in terms of depression scores and response rates. However, regarding the remission rate, bright light did show efficacy compared to control conditions. Due to the limited sample size in the included studies, type II err or may occur. To obtain more conclusive evidence, future studies must employ larger sample sizes.

The microbiome in pregnancy and early life-Highlights from the 11th Maria Delivoria-Papadopoulos Perinatal Symposium.

This review was based on a symposium that examined novel aspects of the microbiome during pregnancy and early life and explored papers published by the lecturers. For example, it showed that bacterial extracellular vesicles derived from the microbiome harboured in various maternal niches, carried bacterial deoxyribonucleic acid, were isolated from the placenta and may have confounded placental microbiome studies. Maternal diet was responsible for the composition and diversity of breast milk microbiota, and may have shaped the offspring's microbiome and influenced their immune components. Probiotics and antibiotics administered perinatally may have had beneficial but also long-lasting adverse effects on offspring.

"Prevalence and Associated Factors of Perinatal Suicide Risk in Spanish Women".

Suicide is one of the leading causes of death worldwide, and in the perinatal period, the trend is increasing, even up to 100 times in the US. No studies have been carried out with validated instruments despite abundant recommendations to do so. This study aims to determine the prevalence of perinatal suicide risk in Spanish women, as well as the factors associated with it. A cross-sectional study was carried out with 908 women in the perinatal stage. Sociodemographic and obstetric variables, anxiety level (GAD-7), social support (DUKE-UNC), risk of intimate violence (WAST), and suicidal ideation (Paykel) were collected. Crude (OR) and adjusted odds ratios (aOR) were calculated using logistic regression for the main risk factors for suicidal ideation. The prevalence of suicidal ideation was 19.3% (175), and suicide attempt 2.4% (22). In the perinatal stage, the risk factors were anxiety [aOR of 1.08 (95% CI: 1.04-1.31)], experiencing a possible situation of intimate partner violence [aOR of 1.59 (95% CI: 1.04-2.43)], and a risk of PPD [aOR of 3.00 (95% CI: 1.86-4.81)]. Perceived social support appears as a protective factor [aOR of 0.97 (95% CI: 0.95-0.99)], along with skin-to-skin contact with the baby during childbirth [aOR 0.50 (95% CI: 0.28-0.88)]. Conclusions: Presenting anxiety or depression, little social support, and living in a possible situation of intimate partner violence are associated with a greater risk of suicidal ideation during the perinatal stage.

The Consequences of A History of Violence on Women's Pregnancy and Childbirth in the Nordic Countries: A Scoping Review.

Violence against women (VAW) is a global challenge also in the childbearing period. Despite high gender equality, there is a high prevalence of VAW in the Nordic countries. This scoping review aims to explore predictors for and consequences of a history of violence on women's pregnancy and childbirth in the Nordic countries, including women's experience of the impact of violence and the interventions used to detect, address consequences, and prevent further violence. The framework by Arksey and O'Malley was followed, and English, Finnish, Icelandic, Norwegian, Danish, and Swedish literature was included. The population was women aged ≥18 residing in the Nordic countries during the perinatal period. Eight databases were searched: MEDLINE, CINAHL, PubMed, PsycINFO, Web of Science, ASSIA, Social Services-, and Sociological abstracts. There was no limitation of the search time frame. The initial screening resulted in 1,104 records, and after removing duplicates, 452 remained. Finally, 61 papers met the inclusion criteria. The results covering the past 32 years indicated that childbearing women with a history of violence are at greater risk of common complaints and hospitalization during pregnancy, fear of childbirth, Cesarean section, breastfeeding difficulties, and physical and mental health problems. While extensive research was found on the associations between a history of and current violence and outcomes related to pregnancy, there was a lack of intervention studies and studies from Finland. Efforts must be made to scientifically test the methods used to reduce and treat the adverse effects of a history of violence and prevent further violence.

Reproductive and transgenerational toxicity of bisphenol S exposure in pregnant rats: Insights into hormonal imbalance and steroid biosynthesis pathway disruption.

Bisphenol S (BPS) is an alternative chemical to bisphenol A commonly used in food packaging materials. It raises concerns due to potential adverse effects on human health. However, limited evidence exists regarding reproductive toxicity from BPS exposure, and the mechanism of associated transgenerational toxicity remains unclear. In this study, pregnant SD rats were exposed to two different doses of BPS (0.05 or 20 mg/kg) from GD6 to PND21. The objective was to investigate reproductive and transmissible toxicity induced by BPS, explore endocrine effects, and uncover potential underlying mechanisms in rats. Perinatal exposure to BPS in the F0 generation significantly decreased the rate of body weight, ovarian organ coefficient, and growth and development of the F1 generation. Notably, these changes included abnormal increases in body weight and length, estrous cycle disruption, and embryonic dysplasia in F1. 4D-DIA proteomic and PRM analyses revealed that exposure to 20 mg/kg group significantly altered the expression of proteins, such as Lhcgr and Akr1c3, within the steroid biosynthetic pathway. This led to elevated levels of FSH and LH in the blood. The hypothalamic-pituitary-ovarian (HPO) axis, responsible for promoting fertility through the cyclic secretion of gonadotropins and steroid hormones, was affected. RT-qPCR and Western blot results demonstrated that the expression of GnRH in the hypothalamus was decreased, the GnRHR in the pituitary gland was decreased, and the expression of FSHß and LHß in the pituitary gland was increased. Overall, BPS exposure disrupts the HPO axis, hormone levels, and steroid biosynthesis in the ovaries, affecting offspring development and fertility. This study provides new insights into the potential effects of BPS exposure on the reproductive function of the body and its relevant mechanisms of action.

A longitudinal study on the association between trait mindfulness and maternal bonding across the perinatal period.

AIMS/BACKGROUND: The mother-to-infant is important for healthy child development. The current study focused on the association between maternal trait mindfulness and the course of maternal bonding from pregnancy to one year postpartum. DESIGN/METHODS: Women participating in a prospective perinatal cohort study (n = 1003) completed online questionnaires on maternal bonding (Pre- and Post-natal Bonding Scale) at 28 weeks of pregnancy, and at 8 weeks, 6 months and 12 months postpartum. At 20 weeks of pregnancy, women completed the Three Facet Mindfulness Questionnaire - Short Form. Multilevel analyses were used to analyse 1) changes in maternal bonding over time and 2) the relationship of these changes with different facets of trait mindfulness measured once during pregnancy. Demographics, obstetrics, and depressive symptoms were controlled for. RESULTS: Results showed that maternal bonding first increased from pregnancy to 8 weeks postpartum and then remained relatively stable throughout the first-year postpartum. On average, women with high scores on acting with awareness and non-judging also scored higher on maternal bonding, but demonstrated a smaller increase in maternal bonding scores over time when compared to women with medium and low scores on these mindfulness facets. Furthermore, non-reacting was also positively associated with the level of maternal bonding but was not related to the course of bonding over time. The main effects of non-reacting and non-judging were not significant after adjusting for covariates. Depressive symptoms and a high educational level were negatively associated with bonding. CONCLUSION: Mindfulness-based interventions may be helpful in supporting expectant mothers who are at risk for suboptimal bonding.

CD14 facilitates perinatal human cytomegalovirus infection in biliary epithelial cells via CD55.

Background & Aims: A high human cytomegalovirus (HCMV) infection rate accompanied by an increased level of bile duct damage is observed in the perinatal period. The possible mechanism was investigated. Methods: A total of 1,120 HCMV-positive and 9,297 HCMV-negative children were recruited, and depending on age, their liver biochemistry profile was compared. Fetal and infant biliary epithelial cells (F-BECs and I-BECs, respectively) were infected with HCMV, and the differences in cells were revealed by proteomic analysis. Protein-protein interactions were examined by coimmunoprecipitation and mass spectrometry analyses. A murine cytomegalovirus (MCMV) infection model was established to assess treatment effects. Results: Perinatal HCMV infection significantly increased the level of bile duct damage. Neonatal BALB/c mice inoculated with MCMV showed obvious inflammation in the portal area with an abnormal bile duct structure. Proteomics analysis showed higher CD14 expression in F-BECs than in I-BECs. CD14 siRNA administration hindered HCMV infection, and CD14-knockout mice showed lower MCMV-induced bile duct damage. HCMV infection upregulated CD55 and poly ADP-ribose polymerase-1 (PARP-1) expression in F-BECs. Coimmunoprecipitation and mass spectrometry analyses revealed formation of the CD14-CD55 complex. siRNA-mediated inhibition of CD55 expression reduced sCD14-promoted HCMV replication in F-BECs. In MCMV-infected mice, anti-mouse CD14 antibody and PARP-1 inhibitor treatment diminished cell death, ameliorated bile duct damage, and reduced mortality. Conclusions: CD14 facilitates perinatal HCMV infection in BECs via CD55, and PARP-1-mediated cell death was detected in perinatal cytomegalovirus-infected BECs. These results provide new insight into the treatment of perinatal HCMV infection with bile duct damage. Impact and implications: Perinatal human cytomegalovirus (HCMV) infection is associated with bile duct damage, but the underlying mechanism is still unknown. We discovered that CD14 expression is increased in biliary epithelial cells during perinatal HCMV infection and facilitates viral entry through CD55. We also detected PARP-1-mediated cell death in perinatal HCMV-infected biliary epithelial cells. We showed that blocking CD14 or inhibiting PARP-1 reduced bile duct damage and mortality in a mouse model of murine cytomegalovirus infection. Our findings provide a new insight into therapeutic strategies for perinatal HCMV infection.
