Background: Systemic sclerosis is a systemic autoimmune disease that also impacts women’s health in very different ways. Methods: This review summarises the most important data on sexuality, fertility, pregnancy, and menopause from the last 10 years. Findings: We identified nine articles with data on sexuality and a prevalence of sexual dysfunction varying between 46 and 90%. Fertility was examined in six studies, with evidence for a negative influence at least on ovarian reserve. With regard to menopause, only three studies are mentioned that show an increased risk for premature menopause in SSc women. Although pregnancies are rare in SSc women after disease onset, there is growing evidence that pregnancies are feasible but go along with a higher maternal and foetal risk compared to healthy controls. Interpretation: SSc is dominated by female gender, but aspects of women’s health influenced by the disease are still often ignored. The treating physician should be aware of the mostly negative impact on sexuality, fertility, and pregnancy and address these topics with the patients to adapt treatment and follow-up examinations to the patients’ complaints and life situation.

Background: Salmonella infections impose a substantial global health burden, with an estimated 95.1 million cases occurring annually. Pregnant women exhibit a heightened vulnerability due to pregnancy-specific immune adaptations and dietary habits that increase their risk of Salmonella exposure, facilitating possible damage to the placental barrier. Despite this significant burden, Salmonella-associated placental pathology remains poorly understood, particularly its impact on foetal development through microstructural alterations. Aim: This study utilised stereology to assess histomorphological and functional alterations in term placentae of Salmonella Typhi-exposed placentae, compared to unexposed controls. Methods: A hospital-based case-control study was conducted in Ghana. Of 237 screened women, 62 placentae were selected for analysis, comprising 31 Salmonella-exposed cases (IgG/IgM-positive in placental and cord blood) and 31 gestational age-matched controls (IgG/IgM-negative). Placental tissues were processed for histology and stereology. Neonatal birthweights were also compared. Results: Stereological assessment revealed significantly higher mean volume densities of syncytial knots in the study group (0.4755 ± 0.04) compared to the controls (0.3342 ± 0.04, p = 0.0219). Syncytial denudation was increased in the study group (0.8113 ± 0.09) relative to the controls (0.1975 ± 0.08, p < 0.0001). Foetal capillary volume density was also significantly elevated in the study group (5.1010 ± 0.32) compared to the controls (3.562 ± 0.47, p < 0.0001). In contrast, intervillous space volume was significantly reduced in the study group (9.5810 ± 0.05) compared to the controls (11.593 ± 0.26, p = 0.0053). Neonates of exposed mothers showed a non-significant reduction in birthweight. Conclusion: Salmonella Typhi exposure in pregnancy induces subtle, yet significant alterations in placental architecture, compromising villous integrity and vascular organisation. Although birthweight may appear unaffected, the observed changes point to reduced placental efficiency and merit further research into their developmental consequences and long-term effects on babies.

The intrauterine environment is increasingly recognised as a critical period for the emergence of mental health vulnerabilities. This review explores how adverse maternal exposures, such as psychological stress, infection, malnutrition, and environmental toxins, can disrupt foetal neurodevelopment via epigenetic mechanisms, contributing to the risk of psychiatric and neurodevelopmental disorders. Focusing primarily on human studies, we synthesise evidence on DNA methylation, histone modifications, and non-coding RNAs as key pathways through which the intrauterine environment influences gene regulation in the developing brain. We examine how timing of exposure, foetal sex, and gene–environment interactions modulate these effects, with particular attention to disorders such as schizophrenia, autism spectrum disorder, depression, and anxiety. The placenta emerges as a central mediator, both reflecting and shaping epigenetic changes in response to maternal signals. We also discuss the reversibility of epigenetic marks and highlight emerging interventions, including nutritional supplementation and maternal mental health support, that may buffer or reverse prenatal epigenetic programming. Methodological challenges are addressed, including tissue specificity and causal inference, and future directions are proposed toward integrating epigenetic biomarkers into early risk assessment and precision mental health and psychiatry. This review emphasises the importance of the prenatal period as a window of vulnerability and opportunity for shaping lifelong mental health. Full article

Iodine deficiency remains one of the most serious global public health challenges, recognised as the leading cause of preventable brain damage worldwide. It is widely accepted as the primary aetiological factor underlying iodine deficiency disorders (IDD). Inadequate maternal iodine intake reduces thyroxine synthesis, impairing foetal brain development and leading to long-term deficits in cognitive function across childhood and adulthood. However, emerging evidence also suggests that excessive iodine intake may disrupt thyroid function, particularly in individuals with underlying thyroid autoimmunity, potentially leading to adverse neurodevelopmental outcomes. In this state-of-the-art review, we examine the effects of iodine nutrition during pregnancy and lactation on child cognitive outcomes. We provide an overview of the recent global iodine status, critically appraise the current evidence linking both iodine deficiency and excess to neurodevelopmental outcomes, and offer expert interpretation of the key findings. We further highlight areas of uncertainty, introduce emerging evidence from contemporary studies, and propose directions for future research to inform and optimise public health policies and clinical practice. Our findings highlight a U-shaped association, whereby both insufficient and excessive iodine exposure during pregnancy and lactation may impair optimal brain development in the offspring.

Perineal injuries are a common complication of vaginal delivery, affecting 75–85% of women. This review examines current knowledge on risk factors, classification, treatment, and quality of life impacts. Risk factors are divided into maternal, foetal, and labour-related categories. Treatment depends on injury severity. First-degree tears can be managed conservatively, with skin glue or suturing—preferably with synthetic absorbable sutures to reduce pain and infection risk. Second-degree tears and episiotomies respond best to continuous non-locking sutures, improving healing, and minimizing postpartum pain. Severe third- and fourth-degree tears require specialised surgical techniques, such as the overlay method for anal sphincter repair, which improves faecal continence. Proper preoperative care, including antibiotics and anaesthesia, enhances outcomes. Episiotomy is controversial; selective use based on clinical indications is recommended over routine practice. Research shows no significant long-term benefits compared to spontaneous tears, and links episiotomy to psychological distress and negative body image. Preventative strategies, like perineal massage and warm compresses during labour, may reduce the risk of severe trauma, particularly in first-time mothers. Perineal trauma can have lasting physical and psychological effects, impacting sexual function, continence, and mental health. Proper diagnosis, treatment, and postpartum care are essential. Future studies should aim to standardise care protocols and explore long-term outcomes to enhance patient quality of life. Full article

Background/Objectives: Physical activity during pregnancy is recognised for its benefits to maternal and foetal health. However, adherence to prenatal exercise programmes is often low due to psychological, physical, and social barriers. This study explored the experiences of women who successfully completed a tailored prenatal exercise programme, “Conscious 9 Months”, aiming to identify factors enabling adherence and providing recommendations for future programme development. Methods: A descriptive qualitative research design was employed using semi-structured, in-depth interviews with ten participants who completed the programme between 2017 and 2019. Thematic Analysis was conducted to explore their experiences. Results: Participants emphasised the transformative nature of the programme, which extended far beyond physical exercise. Three interconnected domains emerged: psychosocial, physical, and psychoeducational. The present article focuses on the psychosocial domain, highlighting the significance of exercising in a group of pregnant women as a key source of support. Additionally, the atmosphere played a crucial role in facilitating the participants’ regular attendance. Finally, the findings indicate that the programme fostered lasting social connections that extended beyond its formal completion. Conclusions: A holistic approach that integrates physical activity with social and emotional support can foster a sense of community and enhance long-term adherence. The design of future programmes should prioritise small group sizes to facilitate peer support and create a safe and welcoming atmosphere to encourage emotional expression. Additionally, sustained engagement beyond pregnancy through follow-up initiatives, family involvement, and postnatal movement programmes can further reinforce long-term participation and promote lasting health benefits for both mothers and their children.

Background/Objectives: Maternal nutrition during pregnancy exerts a significant influence on both maternal and foetal health, as well as long-term child development. Despite its importance, adherence to dietary guidelines among pregnant women remains low. The present study aimed to develop and validate the Italian Pregnancy Nutrition Knowledge Questionnaire (ItPreNKQ), based on national dietary guidelines for the pregnant Italian population, assessing its reliability and validity. Methods: The ItPreNKQ comprised 15 questions covering key topics on nutrition during pregnancy. The questionnaire was validated through item analysis (difficulty and discrimination indices), construct validity, internal consistency, and reliability tests. Results: A total of 145 pregnant Italian women participated in the study. The reliability of the questionnaire was confirmed through a Pearson’s correlation of R = 0.790 and a Cronbach’s alpha of 0.682, indicating strong temporal stability and acceptable internal consistency. Despite good overall performance, the mean knowledge score was 10.6 ± 2.5 out of 15, indicating significant knowledge gaps in specific topics. Conclusions: The ItPreNKQ has been demonstrated to be a reliable and valid tool for the assessment of nutrition knowledge among pregnant Italian women. The tool could be used for assessing nutritional knowledge in prenatal education settings and could be administered in future studies aimed at evaluating the impact of nutritional interventions among pregnant women.

Complex biological processes that enable optimal foetal growth throughout pregnancy are linked to notable haemodynamic and metabolic changes in the mother’s body. An inability to adapt to these changes can affect cardiovascular health. During pregnancy, women may experience mood swings, anxiety, and emotional ambivalence. These symptoms can lead to stress and harm the mental well-being of expectant mothers. It is crucial to know the aspects that can influence the development of cardiovascular problems among pregnant women. Effective management requires identifying risk factors. Applying the PRISMA ScR guidelines, we conducted a scoping review to explore and summarise the evidence regarding the impact of stress and anxiety on cardiovascular health in pregnant women. The following enquiries were looked into as research topics: What effects do anxiety and stress have on a pregnant woman’s cardiovascular health? How is it quantifiable? It is essential to comprehend the physiological changes that the body undergoes throughout pregnancy in order to inform and assist both patients and medical professionals. This makes it possible for them to identify any pathological disorders or risk factors that could worsen the health of expectant mothers. Psychological and cardiovascular risk factor screening, either before or during pregnancy, may be able to uncover circumstances that require specific medical and psychological therapies in order to lower maternal morbidity and death from cardiovascular disease. Our findings underscore the need for systematic psychological and cardiovascular screening during prenatal care to mitigate adverse outcomes and improve maternal–foetal health. Full article

Exposure to bisphenol A (BPA), one of the most widely produced plasticisers, can have a major effect on the growing embryo and the mother during pregnancy; as this is the most vulnerable period, the cutoff established in the legislation does not take this factor into account. Thus, this narrative review aims to highlight the consequences for the foetus and the pregnant woman of maternal and foetal exposure to BPA by analysing epidemiological and experimental studies on humans. Extensive research has examined the effects of BPA on several systems outcomes. Specifically, BPA exposure affects the immune system of the offspring and promotes the development of respiratory diseases, including asthma and wheezing. Moreover, BPA has been negatively associated with children’s neurodevelopment, leading to behavioural changes; autism; and reproductive changes, mainly deviations in anogenital distance, sexual hormone levels and sexual maturation, which can result in infertility. Furthermore, in mothers, BPA exposure may be linked to pre-eclampsia and gestational diabetes mellitus and affects birth parameters, leading to a higher risk of preterm delivery, shorter birth lengths and lower birth weights, although the results were not always consistent. These results demonstrate the urgent need for stricter legislation banning the use of BPA during pregnancy to reduce the hazards to the health and development of the foetus and the unborn child.

From fertilisation to delivery, calcium must be transported into and within the foetoplacental unit for intracellular signalling. This requires very rapid, precisely located Ca²⁺ transfers. In addition, from around the eighth week of gestation, increasing amounts of calcium must be routed directly from maternal blood to the foetus for bone mineralisation through a flow-through system, which does not impact the intracellular Ca²⁺ concentration. These different processes are mediated by numerous membrane-sited Ca²⁺ channels, transporters, and exchangers. Understanding the mechanisms is essential to direct interventions to optimise foetal development and postnatal bone health and to protect the mother and foetus from pre-eclampsia. Ethical issues limit the availability of human foetal tissue for study. Our insight into the processes of placental Ca²⁺ handling is advancing rapidly, enabled by developing genetic, analytical, and computer technology. Because of their diverse sources, the reports of new findings are scattered. This review aims to pull the data together and to highlight areas of uncertainty. Areas needing clarification include trafficking, membrane expression, and recycling of channels and transporters in the placental microvilli; placental metabolism of vitamin D in gestational diabetes and pre-eclampsia; and the vascular effects of increased endothelial Orai expression by pregnancy-specific beta-1-glycoproteins PSG1 and PSG9.

The red blood cell (RBC) membrane is unique and crucial for maintaining structural–functional relationships. Maternal smoking induces significant changes in the morphological, rheological, and functional parameters of both maternal and foetal RBCs, mainly due to the continuous generation of the free radicals. The major aim of this study was to follow the consequences of a secondary stressor, like fungal infection, on the already compromised RBC populations. The impact of Candida infection, a growing health concern, was investigated on four blood sample groups: mothers and their neonates originating from non-smoking versus smoking populations. Here, we searched for phenotypical and molecular markers that precisely reflected the effect of Candida infection on the RBC membrane; this included the level of hemolysis, appearance of morphological variants, formation of the lipid peroxidation marker 4-hydroxyl-nonenal, arrangement of the Band 3 molecules and activation of the Caspase 3. In most of the examined cases, the fungal infection increased the adverse symptoms induced by smoking, indicating a general stress response, likely due to an altered redox state of the cells. However, we were able to identify an atypical phenotype (clustered populations with shrinkage and membrane blebbing) in both the non-smoking and smoking populations, which might be a unique marker for Candida spp. infection.

Background and Objectives: To assess pregnancy and delivery complications in obese women with gestational diabetes mellitus (GDM) and neonatal weight and condition after birth. Materials and Methods: A retrospective tertiary referral centre study included all cases of GDM in the Department of Obstetrics and Gynaecology of the Lithuanian University of Health Sciences (LUHS) Birth Registry from 1 January 2019 to 31 December 2019. We included 583 women with GDM and singleton pregnancies. Women were divided into two groups according to their pre-pregnancy weight: 202 were obese (BMI ≥ 30 kg/m²), and 381 were weight (BMI 18.5–24.9 kg/m²). Survey data were analysed using IBM SPSS Statistics 26.0 and MS Excel 2016 software. A value of p < 0.05 was considered significant. Results: Fasting glycaemia was significantly higher in obese women with GDM than in normal-weight women with GDM (p < 0.001). In addition, fasting glycaemia was higher in obese women with GDM requiring insulin correction than in normal-weight women (p = 0.006). OGTT 0-min glycaemia was higher in obese than in non-obese women with gestational diabetes (p < 0.001). Women with pre-pregnancy obesity had a higher incidence of primary hypertension (p < 0.001), hypertensive disorders in pregnancy (p < 0.001), gestational cholestasis (p = 0.002), polyhydramnios (p < 0.001), induced labour (p < 0.001), and caesarean section (p = 0.015), with emergency caesarean sections being more frequent than planned caesarean sections (p = 0.011) compared to normal-weight women with GDM. Labour dystocia (p = 0.003) and foetal distress (p = 0,019) were more common during labour in obese women. Neonates of these women more often had macrosomia (p < 0.001) and lower Apgar scores at 1 min (p = 0.024) and at 5 min (p = 0.024) compared to neonates of normal-weight women. Conclusions: Obese women with GDM experience more pregnancy complications than normal-weight women with GDM. Full article

Spontaneous preterm birth (sPTB), defined as live birth before 37 weeks of gestational age, is associated with immune dysregulation and pro-inflammatory conditions that profoundly impact newborn health. The question of immune integrity at the maternal-foetal interface is a focus of recent studies centring not only sPTB but the conditions often affiliated with this outcome. Regulatory T cells (Tregs) play a critical anti-inflammatory role in pregnancy, promoting foetal tolerance and placentation. Due to this gestational role, it is hypothesised that decreased or dysfunctional Tregs may be implicated in cases of sPTB. This review examines studies comparing Treg presence in healthy term pregnancies and those with sPTB-associated conditions. Conflicting findings across different conditions and within sPTB itself have been identified. However, notable findings from the research indicate increased proinflammatory cytokines in pregnancies suffering from premature rupture of membranes (pPROM), chorioamnionitis, infection, preeclampsia, and gestational diabetes (GDM). Additionally, reduced Treg levels were identified in preeclampsia, GDM, and pPROM as well as chorioamnionitis presenting with increased Treg dysfunctionality. Treg deficiencies may contribute to health issues in preterm newborns. Current sPTB treatments are limited, underscoring the potential of in utero therapies targeting inflammation, including T cell interventions. Future research aims to establish consensus on the role of Tregs in sPTB and associated conditions and advancing understanding of mechanisms leading to Treg deficiencies in adverse pregnancy outcomes.

During pregnancy, controlling nutrition is crucial for the health of both mother and foetus. While polyphenols have positive health effects, some studies show harmful outcomes during pregnancy. This study evaluated polyphenol intake in a cohort of mother–child pairs and examined its effects on foetal anthropometric parameters. Polyphenol intake was assessed using food frequency questionnaires (FFQs) and 24-h dietary recalls, and analysed with the Phenol-Explorer database. Gestational age and birth measurements were retrieved from medical records. Statistical analyses validated dietary records and assessed polyphenol impact using multivariate generalised linear models. The study found that mean gestational age was 39.6 weeks, with a mean birth weight of 3.33 kg. Mean total polyphenol intake by FFQ was 2231 mg/day, slightly higher than 24-h recall data. Flavonoids and phenolic acids constituted 52% and 37% of intake, respectively, with fruits and legumes as primary sources. This study highlights the use of FFQs to estimate polyphenol intake. Furthermore, the study found associations between polyphenol consumption and anthropometric parameters at birth, with the effects varying depending on the type of polyphenol. However, a more precise evaluation of individual polyphenol intake is necessary to determine whether the effects they produce during pregnancy may be harmful or beneficial for foetal growth.

Placental health and foetal development are dependent upon element homeostasis. Analytical techniques such as mass spectroscopy can provide quantitative data on element concentrations in placental tissue but do not show spatial distribution or co-localisation of elements that may affect placental function. The present study used synchrotron-based X-ray fluorescence microscopy to elucidate element content and distribution in healthy and pathological placental tissue. The X-ray fluorescence microscopy (XFM) beamline at the Australian Synchrotron was used to image trace metal content of 19 placental sections from healthy term (n = 5, 37–39 weeks), foetal growth-restricted (n = 3, <32 weeks, birth weight <3rd centile), postdate (n = 7, >41 completed weeks), and stillbirth-complicated pregnancies (n = 4, 37–40 weeks). Samples were cryo-sectioned and freeze-dried. The concentration and distribution of fourteen elements were detected in all samples: arsenic, bromine, calcium, chlorine, copper, iron, molybdenum, phosphorous, potassium, rubidium, selenium, strontium, sulphur, and zinc. The elements zinc, calcium, phosphorous, and strontium were significantly increased in stillbirth placental tissue in comparison to healthy-term controls. Strontium, zinc, and calcium were found to co-localise in stillbirth tissue samples, and calcium and strontium concentrations were correlated in all placental groups. Molybdenum was significantly decreased in stillbirth, foetal growth-restricted, and postdate placental tissue in comparison to healthy-term samples (p < 0.0001). Synchrotron-based XFM reveals elemental distribution within biological samples such as the placenta, allowing for the co-localisation of metal deposits that may have a pathological role. Our pilot study further indicates low concentrations of placental molybdenum in pregnancies complicated by foetal growth restriction, postdate delivery, and stillbirth. Full article
