Background: Perinatal depression and anxiety are common but often under-detected. Current screening relies on depression-centered instruments and may miss relational drivers including sexual dysfunction, low self-esteem, and psychosocial adversity. Objective: To synthesize evidence on sexual function, self-esteem/body image, and psychosocial context as correlates of perinatal depression and anxiety, and propose a risk-stratified screening framework. Methods: We conducted a narrative evidence synthesis of studies from January 2010 to May 2025 (PubMed/MEDLINE, Scopus, Web of Science) examining associations between perinatal mood/anxiety outcomes and sexual function (Female Sexual Function Index), self-esteem/body image (Rosenberg Self-Esteem Scale), and psychosocial factors (perceived support, intimate partner violence). Results: Sexual dysfunction was highly prevalent and consistently associated with depressive and anxiety symptoms. Longitudinal evidence demonstrated bidirectional pathways: mood symptoms reduced sexual satisfaction, while sexual difficulties intensified relational strain and symptom persistence. Low self-esteem and negative body image mediated links between physiological changes and postpartum depression. Psychosocial adversity, particularly low partner support and intimate partner violence, identified high-risk subgroups with greater severity and slower recovery. Single-instrument approaches (Edinburgh Postnatal Depression Scale alone) may miss pregnancy-specific anxiety and postpartum relational drivers. Conclusions: A staged, risk-stratified model is recommended: assess pregnancy-specific anxiety alongside depression screening in the second/third trimesters; postpartum, selectively add sexual function and self-esteem assessment for women with elevated symptoms or psychosocial risk. Integration within defined referral pathways may improve detection and enable targeted perinatal mental health care. Full article

Background: Fetal growth restriction (FGR) is a major contributor to adverse perinatal outcomes and is primarily driven by placental insufficiency and chronic fetal hypoxia. While arterial Doppler abnormalities are widely used in clinical surveillance, less is known about venous hemodynamics and intracardiac structural adaptations in FGR. In particular, the clinical relevance of foramen ovale (FO) morphometry and inferior vena cava (IVC) Doppler parameters in different FGR phenotypes remains incompletely understood. This study aimed to evaluate FO measurements and IVC Doppler indices in early- and late-onset FGR and to investigate their associations with adverse perinatal outcomes. Methods: This prospective observational study included 240 singleton pregnancies: 120 fetuses with FGR and 120 gestational age-matched appropriate-for-gestational-age controls. FGR was defined according to Delphi consensus criteria and classified as early onset (<32 weeks) or late onset (≥32 weeks). Ultrasonographic assessment included FO and right atrium dimensions, FO-to-right atrium (FO/RA) ratio, IVC diameter, and IVC Doppler indices (pulsatility index [PI], preload index [PLI], and peak velocity index for veins [PVIV]). A composite adverse perinatal outcome (CAPO) was recorded. Receiver operating characteristic (ROC) curve analysis and multivariable logistic regression were performed. Results: Compared with controls, fetuses with FGR exhibited significantly smaller FO dimensions, lower FO/RA ratios, reduced IVC diameters, and higher IVC Doppler indices (all p < 0.05). The FO/RA ratio demonstrated the highest discriminative performance for CAPO (AUC 0.722). In multivariable analysis, a 0.1-unit increase in the FO/RA ratio was independently associated with a reduced risk of CAPO (OR 0.57), whereas higher IVC PI values were associated with an increased risk (OR 2.64). IVC Doppler alterations were less pronounced in early-onset FGR. Conclusions: FO morphometry and IVC Doppler parameters reflect complementary stages of fetal cardiovascular adaptation in fetal growth restriction, with FO changes representing early adaptive responses and IVC Doppler alterations indicating more advanced hemodynamic compromise, and this may provide additional value for perinatal risk stratification.

Background/Objectives: Pre-hospital delivery is an unpredictable event posing significant challenges for Emergency Medical Services (EMS) teams. Despite advances in perinatal care, emergency deliveries outside the hospital environment remain associated with increased maternal and neonatal risks. This study aimed to identify predictors of out-of-hospital delivery in EMS-attended labor cases and determinants of neonatal condition immediately after delivery. Methods: We conducted a retrospective analysis of 5097 EMS records of laboring women in Poland from August 2021 to January 2022, of which 2927 were included in the final study sample. Multivariate logistic regression models with multiple imputation for missing data were used to identify predictors of pre-hospital delivery and adverse neonatal condition (Apgar ≤ 7) in EMS-managed childbirths. Results: Pre-hospital delivery was strongly associated with second-stage labor (OR ≈ 535; p < 0.0001), ruptured membranes (OR ≈ 8.7; p < 0.0001), and fewer previous pregnancies (OR = 0.86; p = 0.018), and showed a trend with higher maternal heart rate (OR = 1.015; p = 0.083). Neonatal status classified as Apgar ≤ 7 was significantly associated with preterm birth (p < 0.0001), absence of fetal movements (OR ≈ 26.4; p = 0.025), and complications during pregnancy (p = 0.036). Complications during labor and lack of prenatal care were not significantly associated with increased risk of pre-hospital delivery in the model. Conclusions: Rupture of membranes, second-stage labor, and fewer previous pregnancies are significant predictors of pre-hospital delivery in EMS-managed cases. Absence of fetal movements and preterm gestation predict worse neonatal outcomes (Apgar ≤ 7). Early identification of these factors may enhance prehospital perinatal care and improve maternal and neonatal prognosis. Full article

An increasing number of young women with hormone receptor-positive (HR+) early breast cancer desire pregnancy after treatment. Prolonged adjuvant endocrine therapy, concerns regarding recurrence risk, and treatment-related fertility decline have historically complicated reproductive decision-making in this population. This narrative review synthesizes current evidence on pregnancy after early HR+ breast cancer, with particular emphasis on prospective data from the POSITIVE trial. We examine the safety of temporary endocrine therapy interruption, the impact of assisted reproductive technologies (ART) in achieving pregnancy, breastfeeding feasibility and impact, hormonal predictors of fertility, pregnancy outcomes and considerations for special populations, including BRCA mutation carriers. Retrospective studies have suggested no adverse survival impact associated with pregnancy after breast cancer. The POSITIVE trial provides prospective evidence that temporary interruption of endocrine therapy to attempt pregnancy does not increase short-term recurrence risk in selected patients. Approximately three-quarters of participants achieved pregnancy. Fertility preservation and ART were commonly used and were not associated with worse short-term oncologic outcomes. Biomarkers such as anti-Müllerian hormone offer supportive but imperfect prediction of fertility potential. Breastfeeding was feasible for many women and did not adversely affect breast cancer outcomes. Available data among BRCA mutation carriers are reassuring but largely observational. Current evidence supports the safety and feasibility of pregnancy after early HR+ breast cancer in carefully selected patients. However, longer follow-up, inclusion of higher-risk populations, and evaluation of newer therapies are needed. Individualized, multidisciplinary counselling remains central to informed decision-making. Full article

Oxidative stress (OS) is a critical regulator of placental development; however, its specific effects on trophoblast biology remain incompletely elucidated. This narrative review synthesizes evidence derived from studies using human placental tissues and trophoblast cell models to delineate how excessive reactive oxygen species (ROS) disrupt molecular and cellular pathways essential for normal placentation. The literature search was restricted to human-based and in vitro investigations. Across these studies, OS was consistently shown to impair mitochondrial function in trophoblasts, resulting in increased mitochondrial ROS generation, loss of mitochondrial membrane potential, and activation of apoptotic signaling cascades. These mitochondrial disturbances were associated with reduced trophoblast proliferation, migration, and invasion, as well as dysregulation of angiogenic balance. Furthermore, several studies reported alterations in mitophagy, involvement of redox-sensitive pathways such as CYP1A1 and KLF9, and the extracellular release of mitochondrial DNA, which was linked to reduced cell viability and increased necrotic cell death. Collectively, the available evidence indicates that OS interferes with key trophoblast-dependent developmental processes, providing mechanistic insight into the pathogenesis of placental dysfunction observed in pregnancy complications such as preeclampsia (PE) and intrauterine growth restriction (IUGR). Elucidation of these pathways may inform the development of targeted therapeutic strategies aimed at preserving placental function and improving adverse pregnancy outcomes. Full article

Pregnancies complicated by diabetes, including pregestational and gestational diabetes mellitus, are associated with increased maternal and fetal morbidity. Early identification of at-risk pregnancies is crucial for timely intervention and improved outcomes. Emerging evidence highlights the interplay of genetic predisposition, epigenetic modifications, and non-invasive biomarkers in the early detection of diabetic pregnancies. Genetic factors influencing insulin signaling, glucose metabolism, and pancreatic β-cell function may contribute to susceptibility to gestational hyperglycemia. Concurrently, epigenetic alterations, such as DNA methylation and histone modifications in maternal and placental tissues, have been linked to dysregulated metabolic pathways and adverse pregnancy outcomes. Non-invasive biomarkers, including circulating cell-free DNA and microRNAs in maternal blood, show promise for early diagnosis by offering a safer and more practical alternative to invasive testing. Integrating genetic, epigenetic, and molecular marker data could enhance risk stratification and enable personalized monitoring and management strategies. This review synthesizes current knowledge on the molecular underpinnings of diabetic pregnancies, evaluates the potential of emerging biomarkers for early diagnosis, and discusses the challenges and future perspectives for translating these findings into clinical practice. Understanding these mechanisms may pave the way for precision medicine approaches, ultimately improving maternal and neonatal outcomes in pregnancies affected by diabetes. Full article

Background and Objectives: Preeclampsia (PE) complicates 2–8% of pregnancies globally, with a higher incidence in developing countries. This condition poses significant risks to maternal and fetal health, contributing substantially to maternal and perinatal mortality, particularly in cases of early-onset PE, which is associated with severe complications. This review aims to synthesize current evidence regarding the predictive utility of ophthalmic artery Doppler for preeclampsia. Current strategies focus on early prediction and prevention to mitigate adverse outcomes and reduce the economic burden of hypertensive disorders in pregnancy. The International Federation of Gynecology and Obstetrics (FIGO) recommends first-trimester screening combining maternal risk factors, mean arterial pressure, serum placental growth factor (PlGF), and uterine artery pulsatility index (UtA-PI). High-risk women are advised to take low-dose aspirin (150 mg daily) until 36 weeks of gestation. Materials and Methods: This review explores an innovative predictive tool for PE: ophthalmic artery (OA) Doppler. Results: As a non-invasive and easily accessible method, OA Doppler provides valuable insights into intracranial vascular resistance, offering potential advantages in early risk assessment, particularly for preterm PE, the most severe form of the disease. Conclusions: Our findings suggest that OA Doppler may serve as a promising adjunct in PE screening, enhancing the early identification of high-risk pregnancies and improving clinical outcomes. Further research is warranted to validate its role in routine prenatal care. Full article

Hepatitis E virus (HEV) is a zoonotic pathogen that can infect pregnant women and cause adverse pregnancy outcomes, including miscarriage and preterm delivery. The previous study demonstrated that HEV genotype 3 (HEV-3) inhibits complete autophagic flux in both mouse placental tissue and human trophoblast cells (JEG-3), evidenced by reduced expression of ATG proteins (including LC3, Beclin1, ATG4B, ATG5, and ATG9A) and accumulation of p62. However, the specific regulatory pathway involved remains unclear. Thus, eukaryotic expression vectors for HEV open reading frames (ORFs) were constructed, and ORF2 and ORF3 proteins were transiently overexpressed in JEG-3 cells via liposome transfection. While both ORF2 and ORF3 significantly reduced LC3B protein levels (p < 0.01), only ORF2 induced p62 accumulation (p < 0.01), indicative of autophagic inhibition, which indicates that ORF2 was the key viral protein mediating autophagy suppression in JEG-3. The results of WB and RT-qPCR showed that ORF2 suppressed the PI3K/Akt/mTOR pathway while enhancing nuclear translocation of TFEB (p < 0.01) and AMPK phosphorylation (p < 0.01), suggesting paradoxical activation of upstream autophagy regulators. Through co-transfection of mCherry-LC3 with ORF2, co-localization studies, and AlphaFold 3-based intermolecular interaction predictions, we propose that ORF2 directly binds LC3B to block autophagosome formation. Finally, co-immunoprecipitation confirmed physical interaction between HEV ORF2 and LC3B, elucidating the molecular mechanism of HEV-induced autophagy suppression in trophoblasts. These findings reveal the molecular mechanism by which HEV inhibits autophagy leading to miscarriage in mice, providing new insights into HEV-induced reproductive damage. Full article

Background: Respiratory Syncytial Virus is a predominant source of morbidity and mortality, particularly among babies, the elderly, and immunocompromised patients. Recent developments in RSV vaccines, approved by the FDA for high-risk groups, have highlighted the necessity for post-marketing surveillance to evaluate their real-world safety and efficacy. Method: This study utilized data from the Vaccine Adverse Event Reporting System (VAERS) covering RSV vaccine administration between 2023 and May 2025. The VAERS database reported data on vaccine types, including Arexvy^®, Abrysvo^®, and mRESVIA^® was analyzed for adverse events and vaccination errors. The demographic information, vaccination trends, and hospitalizations post-vaccination among the vaccinated individuals were accessed. Results: The analysis revealed that the most common adverse events were mild, such as injection site pain, erythema, fatigue, and extremity pain. The data also showed a gradual increase in hospitalization rates from 4.8% in 2023 to 7.5% in 2025. Vaccination errors, including inappropriate administration during pregnancy and excess doses, were also observed. A notable trend was the growing proportion of patients who experienced no adverse events, with the highest rate of symptom-free reports seen in 2025 (25.9%). Conclusions: RSV vaccines demonstrate a generally acceptable safety profile based on post-marketing surveillance data. However, the observed increase in hospitalization rates, vaccination errors, and pregnancy-related outcomes warrants continued active surveillance and cautious interpretation. Full article

Housing insecurity is a growing public health concern linked to adverse health outcomes and lifelong vulnerability. Although housing is a well-established social determinant of health, this review employs a life-course framework to explain how housing insecurity contributes to the accumulation of health inequities and chronic disparities across the different stages of human development. A rapid review was conducted across PubMed, Google Scholar, SCOPUS, and Web of Science, focusing on peer-reviewed studies published between 1991 and 2025. Studies were screened using predefined eligibility criteria, and the selection process was documented through a PRISMA flow diagram. Fifty-five studies met the inclusion criteria. Housing insecurity was consistently associated with adverse health outcomes across pregnancy, infancy, childhood, adolescence, adulthood, and older age. Each life stage presents distinct vulnerabilities shaped by environmental and social conditions, which are manifested through physiological and psychosocial pathways. While physical health effects were most frequently reported, developmental and mental health impacts accumulated over time, amplifying overall burden. The findings demonstrate a clear life-course pathway linking housing insecurity to immediate and long-term health risks. Early-life disadvantages create lasting, preventable consequences, underscoring the urgent need for policies that embed housing stability within broader public health planning. Full article

Background: Maternal overweight and obesity, which show a rising trend globally, are associated with adverse pregnancy outcomes and long-term health risks for both mother and child. Awareness and understanding of these risks among women of reproductive age are essential for effective prevention and early intervention. Methods: We conducted a cross-sectional survey among 958 women planning pregnancy, currently pregnant or breastfeeding to assess their knowledge and attitudes regarding overweight and obesity in the perinatal period. The questionnaire covered lifestyle behaviors, breastfeeding practices, and knowledge related to overweight and obesity in pregnancy. Results: Overall knowledge regarding the consequences of maternal overweight and obesity was low, with notable deficits in understanding the associated health risks and frequent misconceptions about dietary recommendations during pregnancy. Awareness gaps were particularly noticeable in domains related to fetal outcomes and recommended energy requirements across pregnancy. Excessive gestational weight gain was reported in over 75% of pregnancies, including among women with normal body mass index. Participation in antenatal classes, current breastfeeding and older age were significantly associated with higher knowledge; however, these factors together explained only 6.2% of variability. Still, several key aspects were not well recognized despite high educational attainment and frequent contact with maternity care services. Conclusions: Our study highlights a clear and urgent need for better, more targeted educational strategies to improve women’s understanding of metabolic health and nutrition before and during pregnancy. The low explained variance indicates that maternal knowledge is influenced by multifactorial and not easily captured determinants, emphasizing the need for comprehensive and individualized educational approaches. Enhancing maternal awareness could support better health outcomes for both mothers and their offspring. Full article

Mpox is an emerging zoonotic infection caused by the Monkeypox virus, an Orthopoxvirus with increasing global relevance following the 2022 multinational outbreak. Historically endemic to Central and West Africa, the disease has evolved from sporadic zoonotic transmission to sustained human-to-human spread, particularly through close physical and intimate contact. Clinical manifestations typically include fever, lymphadenopathy, and progressive mucocutaneous lesions, although severity varies according to viral clade, immune status, and comorbidities. The 2022 outbreak, predominantly associated with the Clade IIb variant, was characterized by milder disease, localized lesions, and reduced mortality compared with the more virulent Clade I variant. Despite this, severe outcomes remain possible, particularly in vulnerable groups such as children, pregnant individuals, immunocompromised patients, and persons with extensive dermatological disorders. Diagnosis relies primarily on polymerase chain reaction testing from lesion-derived samples, with genomic sequencing serving as a complementary tool for epidemiological surveillance. Management is largely supportive, though antivirals such as tecovirimat may be considered in severe cases or in high-risk populations. Data regarding therapeutic safety in pregnancy are limited; however, tecovirimat appears to have the most favorable profile, whereas cidofovir and brincidofovir remain contraindicated. Prevention strategies include targeted vaccination with the non-replicating Modified Vaccinia Ankara–Bavarian Nordic vaccine, used for both pre- and post-exposure prophylaxis, particularly in individuals at elevated risk. Given the evolving epidemiological profile, the potential for vertical transmission, and the risk of adverse perinatal outcomes, Mpox infection during pregnancy poses unique clinical challenges. This review synthesizes current evidence on virology, clinical presentation, diagnosis, prevention, and management, with an emphasis on obstetric considerations and public health implications.

Objective: To investigate the impact of proteinuria severity on obstetric and neonatal outcomes and to assess the predictive value of 24 h urinary protein excretion, both alone and within a multivariable model, for adverse pregnancy outcomes. Methods: This retrospective cohort study included 203 pregnant women with proteinuria who were classified into mild (≥0.3 g/day and <3.0 g/day, n = 50), severe (≥3.0 g/day and <5.0 g/day, n = 67), and massive (≥5.0 g/day; n = 86) groups based on 24 h urine protein levels. Maternal and neonatal outcomes were compared between these groups. Correlation analysis, receiver operating characteristic (ROC) curve analysis, and multivariable logistic regression were used to evaluate the predictive value of proteinuria for obstetric complications and identification of increased risk of early delivery. The AUC values of the proteinuria-only model and the multivariable model were compared using the DeLong test, as both models were derived from the same dataset and therefore represented correlated ROC curves. Results: The incidence of obstetric complications was significantly higher in the severe (68.7%) and massive (81.4%) proteinuria groups compared with the mild group (32.0%; p < 0.001). Increasing proteinuria severity was associated with earlier gestational age at delivery, lower birth weight, and higher rates of fetal growth restriction (all p < 0.001). The 24 h proteinuria level demonstrated moderate predictive ability for obstetric complications (AUC 0.73; 95% CI 0.66–0.80). A multivariable model including nephrotic-range proteinuria (≥3 g/day) and gestational age at diagnosis showed improved discriminatory performance compared with proteinuria alone (AUC 0.81; 95% CI 0.75–0.88). The model based on continuous 24 h proteinuria yielded an AUC of 0.73 (95% CI, 0.66–0.80) for identifying pregnancies at increased risk of obstetric complications. The multivariable model showed a numerically higher AUC of 0.81 (95% CI, 0.73–0.86); however, the difference between the two AUCs was not statistically significant according to the DeLong test (z = 0.82, p = 0.41). Conclusions: The severity of maternal proteinuria is associated with a higher likelihood of adverse maternal and neonatal outcomes, and higher proteinuria levels appear to show a graded association with increasing risk. A multivariable model integrating proteinuria with key clinical parameters demonstrated moderate discriminatory ability for obstetric complications, may support a more holistic approach to risk stratification in clinical practice.

Background and Objectives: Antiretroviral therapy used during pregnancy in HIV infected women effectively reduces vertical transmission, though concerns about potential adverse newborn outcomes persists. This study focused on prematurity and low birth weight in antiretroviral HIV-exposed children in two major Romanian centers, Bucharest and Constanța, in the context of free access to antiretroviral treatment for pregnant women in Romania since 2001. Materials and Methods: A retrospective observational study was performed including couples of HIV-infected women and their live singleton newborns from 2006 and 2012. Preterm delivery was defined as birth before week 37 and low birth weight was defined as birth weight less than 2500 g in full-term babies. Results: A total number of 352 children and 313 women were enrolled. Mean maternal age at delivery was 23.1 years. Mean newborn birth weight was 2726 g. In the children group, 191 (54.2%) were boys, and the rate of HIV transmission was 13.9%. The prematurity rate was 21.5% and low birth weight rate was 25.56%. Preterm birth was associated with high HIV RNA in the third trimester, HIV-positive final status in infants, and vaginal delivery. Low birth weight was associated with lack of antiretroviral treatment during pregnancy and HIV-positive status in infants. No association was found between prematurity and low birth weight in full-term newborns and exposure to any antiretroviral class, any specific antiviral drug, or with any number of maternal regimens, duration of antiretroviral treatment prior to conception, or maternal exposure during puberty. Conclusions: In our study, preterm birth was significantly associated with HIV vertical transmission in newborns and with exposure to high maternal viral replication during the last trimester of pregnancy. Low birth weight in full-term babies was significantly associated with lack of antiretroviral exposure in utero in our analysis. Full article

Maternal undernutrition remains a major modifiable risk factor for adverse pregnancy outcomes. Dietary supplements are widely used to bridge nutritional gaps, but their efficacy, safety, and quality control remain controversial. This review critically evaluates the mechanisms, clinical evidence, and quality assurance of key supplements (folic acid, iron, vitamin D, calcium, iodine, omega-3 PUFA, choline, and multiple micronutrients) specifically in pregnant and postpartum women. We highlight that while folic acid (400–800 µg/d) and iron supplementation reduce neural tube defects by >70% and maternal anaemia by 30–50%, respectively, high-dose antioxidant cocktails (vitamins C + E) have shown no benefit and potential harm in large RCTs. Up to 18–40% of commercially available prenatal supplements contain undeclared pharmaceuticals, heavy metals, or incorrect dosages, underscoring the urgent need for advanced analytical methods (LC-MS/MS, HRMS, NMR). We propose the GAPSS (Genotype–Analytics–Physiology–Safety–Sustainability) framework for future personalised maternal nutrition. Rigorous, pregnancy-specific quality control combined with biomarker-guided supplementation is essential to maximise benefits and minimise risks. Full article
