Hyaluronic acid (HA) is a ubiquitous glycosaminoglycan with distinct biological functions, dependent on its molecular weight. High-molecular-weight HA (HMWHA) primarily exhibits structural and anti-inflammatory roles, whereas low-(LMWHA) and very low-molecular-weight HAs (vLMWHA) actively participate in tissue regeneration and angiogenesis. This review highlights the pivotal roles of HA across the female reproductive lifespan, emphasizing how molecular weight dictates its therapeutic potential. In gynecology, LMWHA effectively alleviates symptoms of genitourinary syndrome of menopause, restores vaginal architecture, and mitigates complications following pelvic radiotherapy, improving both tissue integrity and patient quality of life. vLMWHA shows promise in enhancing viral clearance and lesion regression in human papillomavirus (HPV) infections. In obstetrics, HMWHA plays crucial roles in implantation, immunotolerance, and embryogenesis and maintains cervical barrier integrity to prevent ascending infections and preterm birth. Moreover, emerging clinical evidence supports oral HMWHA supplementation for reducing pregnancy complications, such as threatened miscarriage, subchorionic hematomas, and preterm delivery. This review underscores the necessity of considering HA’s molecular weight to optimize interventions in gynecological and obstetric care, offering tailored strategies to support women’s health throughout their lives.

Human T-cell lymphotropic virus (HTLV), a retrovirus associated with severe conditions such as leukemia/lymphoma and myelopathy, exhibits variable global prevalence, with higher rates observed in regions such as northeastern Brazil and sub-Saharan Africa. While intrauterine transmission can occur via viral expression in placental tissue and contact with umbilical cord blood, the predominant route is vertical transmission through breastfeeding. Diagnostic testing, particularly serological screening with ELISA and confirmatory methods such as Western blot and PCR, is essential for early detection during pregnancy. The implementation of prenatal screening programs, as seen in Japan and Brazil, has proven effective in reducing vertical transmission by guiding interventions such as breastfeeding cessation in infected mothers. Beyond clinical implications, the psychosocial impact on affected pregnant women highlights the need for an interdisciplinary approach. Although the association between HTLV infection and adverse obstetric outcomes remains controversial, studies suggest increased risks of preterm birth, low birth weight, and other neonatal complications. Given the importance of early diagnosis and prevention, universal prenatal screening protocols represent a critical strategy to reduce viral transmission and its long-term consequences. Full article

Antiphospholipid syndrome (APS) is an autoimmune disorder characterized by venous and arterial thrombosis and obstetric complications, driven by antiphospholipid antibodies (APLAs). This review synthesizes the latest advancements and current understanding, diagnosis, and treatment of APS. APLAs, including lupus anticoagulant (LAC), anticardiolipin (aCL), and anti-β2-glycoprotein I (aβ2-GPI), interfere with coagulation and endothelial function, as well as with placental health. APS can be primary or secondary; it is often associated with systemic autoimmune diseases like lupus. The pathogenesis of APS remains only partially understood. APLAs promote thrombosis through endothelial damage, platelet activation, and inflammatory signaling pathways. Laboratory diagnosis relies on persistent positivity for APLAs and LAC through tests like ELISA and clotting assays, following a three-step confirmation process. New integrated test systems have been introduced to improve standardization. Classification criteria have evolved, with the 2023 EULAR-ACR criteria providing a weighted, domain-based scoring system, enhancing diagnostic precision. Catastrophic APS (CAPS) is a severe, rare manifestation of APS, characterized by multi-organ failure due to rapid, widespread microthrombosis and systemic inflammation, which requires urgent anticoagulation. Seronegative APS is proposed for patients with clinical features of APS but negative standard antibody tests, possibly due to non-criteria antibodies or transient immunosuppression. Treatment primarily involves long-term anticoagulation with vitamin K antagonists; direct oral anticoagulants are generally not recommended. APS diagnosis and management remain complex due to clinical heterogeneity and laboratory challenges. Continued refinement of diagnostic tools and criteria is essential for improving outcomes in this life-threatening condition. Full article

Objectives: To evaluate the association between late CVS (placental biopsy, later than 13 weeks of gestations) and complications between sampling and delivery in 8599 cases in the Department of Obstetrics and Gynecology of a private hospital Podobnik, Zagreb, Croatia. Methods: Late chorionic villus sampling under ultrasound guidance was carried out in prospective monocentric cohort study of 7859 (91.4%) cases in the second trimester and 700 (8.6%) cases in the third trimester of pregnancy. Out of 8599 late CVS cases, 1476 (17.2%) were performed because of suspicious ultrasonographic findings. Results: In 43 patients (0.50%), complications were found between sampling and delivery. There were only 12 (0.15%) spontaneous abortions four to six weeks after late CVS (before 28 weeks). We found 190 (2.3%) chromosomal abnormalities. In the group with suspicious ultrasonographic findings, comparing 1476 cases, we found significant oligohydramnios in 375 (25.4%), significant polyhydramnios in 197 (13.3%) and chromosomal abnormalities in 125 (8.5%) cases. Among the 190 patients with chromosomal abnormalities, ultrasonographic findings were detected in 98 (49.2%) after the 22th week of pregnancy. Conclusions: Late CVS is a safe method of invasive prenatal diagnosis with lower spontaneous abortions rate (0.15%). This method, applicable after 13 weeks of gestation, offers a more flexible approach to invasive prenatal diagnosis of chromosome abnormalities, in very specialized fetal-maternal centres for this method.

Pregnancy rhinitis (PR) is a transient, non-infectious nasal condition affecting a significant number of pregnant women, yet often remains underdiagnosed or misclassified. It can substantially impact maternal quality of life, sleep, and even fetal oxygenation. This narrative review explores the current understanding of PR, including hormonal and vascular mechanisms, clinical criteria, and therapeutic approaches considered safe during pregnancy. Despite increasing recognition, the differentiation between PR and other rhinitis forms remains challenging. Limited therapeutic options and the absence of standard diagnostic guidelines further complicate management. Evidence supports a multifactorial etiology involving estrogen, progesterone, and placental growth factors. Non-pharmacologic strategies are first-line, while pharmacological interventions are cautiously employed. PR is a distinct and clinically relevant condition requiring increased awareness among ENT and obstetric professionals. Future research should focus on standardized diagnostic criteria and evidence-based treatment protocols to improve maternal–fetal outcomes. Full article

Background: Antiphospholipid syndrome (APS) is one of the highest risk factors for obstetric complications. This article contains a case report of a patient with obstetric APS who experienced fetal loss during their first pregnancy and experienced a successful second pregnancy upon treatment with acetylsalicylic acid (ASA), low-molecular-weight heparin (LMWH), and hydroxychloroquine (HCQ). We compare placental pathology in these two pregnancies and discuss the impact of antiphospholipid antibodies and clinical management on pregnancy outcomes. We also propose methods to monitor obstetric antiphospholipid syndrome (OAPS) patients during pregnancy. Methods: A 26-year-old woman presented with a history of stillbirth at 25 weeks of pregnancy due to placental insufficiency. Before pregnancy, she experienced symptoms suggestive of autoimmune disease (thrombocytopenia, recurrent mouth aphthous ulcers, and Raynaud’s phenomenon) but had no diagnosis. Placental dysfunction correlated with the high ratio of sFlt-1/PIGF (soluble fms-like tyrosine kinase 1 and the placental growth factors index). Laboratory tests revealed the presence of antinuclear antibodies (ANAs) and triple positivity for antiphospholipid antibodies (aPLs). Results: Following the initiation of treatment for OAPS and regular monitoring consistent with current guidelines, the patient conceived and successfully delivered a healthy child. Conclusions: Adequate therapy and close monitoring during pregnancy, including clinical observation, placental biomarkers and regular ultrasonography, may help to reduce the risks and increase chances for optimal pregnancy outcomes. Additionally, pathological examination and clinical collaboration are essential components in future pregnancy counseling and should be a part of multidisciplinary management. Full article

Background/Objectives: Pregnancy has been considered a risk factor for severe SARS-CoV-2 infection, as well as for adverse maternal and neonatal outcomes. This study aimed to assess the clinical impact of COVID-19 on pregnant women managed at a Spanish tertiary care hospital across different phases of the pandemic. Methods: A retrospective observational study was conducted at Dr. Balmis General University Hospital (Alicante, Spain) between March 2020 and May 2023. All pregnant women who received hospital care with confirmed SARS-CoV-2 infection were included. Maternal and neonatal outcomes were analyzed and compared with the 6120 total births recorded during the same period. Results: A total of 249 pregnant women with COVID-19 were included, with 30.8%, 25.0%, and 7.9% hospitalized during each respective pandemic phase. The overall incidence of infection was 41 cases per 1000 births. Hospitalized pregnant women showed significantly higher rates of preterm birth, labor induction (70.4% vs. 47.0%; OR: 2.67; 95% CI: 1.12–6.43), and cesarean delivery (46.9% vs. 24.9%, OR: 2.60; 95% CI: 1.27–5.50). Neonatal outcomes included lower Apgar scores, increased admission to the neonatal unit (25.8% vs. 8.2%, p = 0.007), and a higher rate of neonatal complications (23.3% vs. 7.7%, p = 0.015). Maternal obesity and non-Spanish nationality were associated with more severe maternal disease. Vaccination against SARS-CoV-2 significantly reduced the risk of hospitalization due to the infection (OR: 0.30; 95% CI: 0.13–0.69). Conclusions: Pregnant women admitted with COVID-19 had increased risks of adverse obstetric and neonatal outcomes, underscoring the importance of preventive strategies, such as vaccination.

Background: This study was designed to evaluate and contrast the surgical outcomes between coaxial robotic single-site myomectomy (RSSM) performed using the da Vinci Xi system and da Vinci SP system. Methods: A retrospective review was conducted on 81 women who underwent coaxial RSSM and 108 women who underwent myomectomy with the da Vinci SP system between October 2020 and January 2024. Propensity score matching was performed based on myoma count, the dominant myoma’s maximum diameter, and the myoma type according to the International Federation of Gynecology and Obstetrics (FIGO) classification. Patient characteristics and surgical outcomes were evaluated and compared between the two groups. Results: Compared to the SP group, the coaxial RSSM group showed significantly lower estimated blood loss (102.33 ± 61.01 vs. 203.98 ± 163.15 mL, p < 0.001), shorter operative time (91.22 ± 18.25 vs. 148.69 ± 45.62 min, p < 0.001), and smaller hemoglobin decrement (1.69 ± 0.93 vs. 2.85 ± 1.30, p < 0.001). However, hospital stay was shorter in the SP group than in the coaxial group (2.06 ± 0.24 vs. 4.07 ± 0.76 days, p < 0.001). There were no statistically significant differences in postoperative complications, including ileus, fever, or wound dehiscence. Additional comparisons using cases performed by four different surgeons yielded results consistent with the one-to-one surgeon comparison. Conclusions: Coaxial RSSM was associated with a shorter operative time and lower blood loss compared to SP myomectomy. A prospective study is warranted to validate and further compare the surgical outcomes of the two techniques. Full article

Background: Hypotension following epidural labor analgesia (ELA) is its most common complication, affecting approximately 20% of patients and posing risks to both maternal and fetal health. As digital tools and predictive analytics increasingly shape perioperative and obstetric anesthesia practices, real-world implementation data are needed to guide their integration into clinical care. Current monitoring practices rely on intermittent non-invasive blood pressure (NIBP) measurements, which may delay recognition and treatment of hypotension. The Hypotension Prediction Index (HPI) algorithm uses continuous arterial waveform monitoring to predict hypotension for potentially earlier intervention. This clinical trial evaluated the feasibility, acceptability, and efficacy of continuous HPI-guided treatment in reducing time-to-treatment for ELA-associated hypotension and improving maternal hemodynamics. Methods: This was a prospective randomized controlled trial design involving healthy pregnant individuals receiving ELA. Participants were randomized into two groups: Group CM (conventional monitoring with NIBP) and Group HPI (continuous noninvasive blood pressure monitoring). In Group HPI, hypotension treatment was guided by HPI output; in Group CM, treatment was based on NIBP readings. Feasibility, appropriateness, and acceptability outcomes were assessed among subjects and their bedside nurse using the Acceptability of Intervention Measure (AIM), Intervention Appropriateness Measure (IAM), and Feasibility of Intervention Measure (FIM) instruments. The primary efficacy outcome was time-to-treatment of hypotension, defined as the duration between onset of hypotension and administration of a vasopressor or fluid therapy. This outcome was chosen to evaluate the clinical responsiveness enabled by HPI monitoring. Hypotension is defined as a mean arterial pressure (MAP) < 65 mmHg for more than 1 min in Group CM and an HPI threshold < 75 for more than 1 min in Group HPI. Secondary outcomes included total time in hypotension, vasopressor doses, and hemodynamic parameters. Results: There were 30 patients (Group HPI, n = 16; Group CM, n = 14) included in the final analysis. Subjects and clinicians alike rated the acceptability, appropriateness, and feasibility of the continuous monitoring device highly, with median scores ≥ 4 across all domains, indicating favorable perceptions of the intervention. The cumulative probability of time-to-treatment of hypotension was lower by 75 min after ELA initiation in Group HPI (65%) than Group CM (71%), although this difference was not statistically significant (log-rank p = 0.66). Mixed models indicated trends that Group HPI had higher cardiac output (β = 0.58, 95% confidence interval −0.18 to 1.34, p = 0.13) and lower systemic vascular resistance (β = −97.22, 95% confidence interval −200.84 to 6.40, p = 0.07) throughout the monitoring period. No differences were found in total vasopressor use or intravenous fluid administration. Conclusions: Continuous monitoring and precision hypotension treatment is feasible, appropriate, and acceptable to both patients and clinicians in a labor and delivery setting. These hypothesis-generating results support that HPI-guided treatment may be associated with hemodynamic trends that warrant further investigation to determine definitive efficacy in labor analgesia contexts.

Background/Objectives: Renal transplantation (RT) represents the optimal treatment for end-stage renal disease (ESRD), offering improved quality of life and restored fertility in women post-transplant. While post-transplant pregnancies are possible, they can lead to complications including pre-eclampsia, graft dysfunction, and other adverse outcomes. This study evaluates existing literature to assess pregnancy’s impact on kidney transplantation outcomes, specifically long-term graft function and survival. Methods: We conducted a systematic review of English-language literature from January 2000 to September 2023 across multiple databases, following PRISMA guidelines. We established inclusion criteria focusing on graft function and adverse events. Two independent reviewers performed data extraction, and we assessed risk of bias using the ROBINS-I tool. Results: From 4917 articles, we included 26 studies encompassing 1202 pregnancies in 902 kidney transplant recipients. Mean maternal age was 30.8 years, with an average interval of 52 months between transplant and pregnancy. Pre-pregnancy hypertension occurred in 54.2% of cases, and pre-eclampsia developed in 25.7%. The live birth rate reached 70.5%, while miscarriage, stillbirth, and neonatal death rates were 11.3%, 2.7%, and 2.5%, respectively. We noticed graft dysfunction during pregnancy in 20.2% of cases. Though kidney function often deteriorated temporarily, most patients recovered post-delivery. Discussion: Post-transplant pregnancies remain viable but high-risk, with elevated rates of obstetric complications. Our findings highlight the need for standardized data collection and reporting to better understand and manage pregnancy’s impact on graft outcomes. Conclusions: With appropriate management, pregnancy in kidney transplant recipients is feasible, though it carries elevated risks of obstetric complications. We recommend further multicenter studies with standardized data collection to improve understanding and outcomes. Full article

Background: Uterine rupture is a rare but severe obstetric complication with significant maternal and neonatal consequences. While partial uterine ruptures (PURs) are generally associated with less severe outcomes, complete uterine ruptures (CURs) carry a higher risk of serious impact on both mother and child. The present study aimed to evaluate outcomes and identify risk factors for each type of rupture, and also to define high- and low-risk uterine ruptures based on clinical outcomes. Methods: A retrospective analysis of 112 uterine rupture cases, including 29 CURs and 83 PURs, was conducted at the Women’s Hospital of the University of Cologne from October 2010 to January 2021. Results: Maternal outcomes revealed that CUR was associated with higher risks of prolonged hospitalization (p = 0.003), postpartum hemorrhage (p < 0.001), maternal transfusion (p = 0.003), and ICU transfer (p = 0.004) compared to PUR. Neonatal outcomes showed a significantly higher risk of severe acidosis (p < 0.001), low APGAR scores (p < 0.001), NICU transfers (p = 0.004), and resuscitation needs (p = 0.016) in CUR cases. Factors increasing the risk of CUR included pathological CTG (OR = 1.9, 95% CI: 0.99–7.14, p = 0.05), abdominal pain (OR = 2.63, 95% CI: 1.10–6.25, p = 0.03), previous vaginal birth (OR = 7.14, 95% CI: 0.025–20, p < 0.001), and no uterine contractions (OR = 7, 95% CI: 1.21–40.56, p = 0.03). A previous cesarean section significantly increased the risk of CUR (OR = 4.94, 95% CI: 1.38–17.67, p = 0.014), whereas more than two cesarean sections reduced the risk (OR = 0.66, 95% CI: 0.13–3.22, p = 0.61). A comparison of CUR with maternal and neonatal high-risk rupture groups revealed that low gestational age and a history of previous cesarean sections were significant risk factors for neonatal high-risk rupture. Conclusion: Vaginal birth and abdominal pain were identified as key risk factors for CUR, which lead to severe maternal and neonatal outcomes. Recognizing these risk factors can help clinicians optimize risk stratification and decision-making, and enhance monitoring strategies to prevent adverse outcomes. Full article

Background/Objectives: Pregnancies complicated by idiopathic polyhydramnios are linked to a heightened risk of numerous maternal and perinatal complications. We aim to study the implications of polyhydramnios in term pregnancies complicated with gestational diabetes mellitus (GDM). Methods: A prospective cohort study including 340 GDM cases was conducted. An ultrasound scan was conducted at term between 37 and 40 weeks and amniotic fluid volume (AFV) was assessed by measuring the amniotic fluid index (AFI) and the single deepest pocket (SDP). Maternal demographics and obstetric and perinatal outcomes were evaluated after delivery. We performed comparisons between groups with normal AFV and polyhydramnios (AFI ≥ 24 cm or SDP ≥ 8 cm), and between groups with normal and increased AFV (AFI or SDP ≥ 75th centile). A multivariate logistic regression analysis was performed to study association between AVF measurements and adverse maternal and perinatal outcomes. Results: We found that women with GDM and polyhydramnios at term had a higher risk of maternal (54.3 vs. 27.5%, p < 0.001) and perinatal adverse outcomes (65.7% vs. 46.5%, p < 0.03). The increased AFV group showed a higher risk of fetal overgrowth (LGA: 21.4% vs. 8.2%, p < 0.001 and macrosomia: 19.8% vs. 5.4%, p < 0.001, respectively) and a lesser risk of delivering an SGA fetus (6.3% vs. 13.6%, respectively). Both AFI and SDP showed a significant correlation with newborn weight (r = 0.27; p < 0.001 and r = 0.28; p < 0.001, respectively) and newborn centile (r = 0.26; p < 0.001 and r = 0.26 for both). Subsequent to conducting a multivariate logistic regression analysis adjusted for pregestational BMI, nulliparity, and insulin treatment, both AFI and SDP were significantly associated with perinatal complications, but AFI showed a stronger association with fetal overgrowth (aOR 1.11; p = 0.004 for a LGA fetus and aOR 1.12; p = 0.002 for macrosomia) and with lower risk of delivering an SGA fetus (aOR 0.89; p = 0.009) or IUGR fetus (aOR 0.86; p = 0.03). ROC analysis showed a poor diagnostic performance of both AFI and SDP for identifying macrosomia (AUC 0.68 for AFI, and 0.65 for SDP). Conclusions: Detection of polyhydramnios at term, whether using AFI or SDP, identifies a subgroup of women with gestational diabetes with higher risks of obstetric and perinatal complications. Cases with increased AFV (AFI ≥ 18 cm or SDP ≥ 6.5 cm) are also associated with an increased risk of fetal overgrowth and may require more intensive monitoring for management and optimal delivery timing, with the aim of improve perinatal outcomes.

Antenatal corticosteroids are widely used to prevent newborn morbidity and mortality in special obstetric circumstances, especially in preterm birth, but there are ongoing concerns about possible neutral or even detrimental short- and long-term effects in pregnancies complicated by fetal growth restriction. Fetuses with growth restriction may be a subset of preterm infants with a particular vulnerability to steroid exposure. The current scientific evidence on exogenous antenatal corticosteroid effects in this population is not conclusive. Gestational age (early versus late) is a critical issue to assess regarding their use as standard care in this special obstetric circumstance. Full article

Background: Following the results of the Laparoscopic Approach to Carcinoma of the Cervix (LACC) trial, doubts have arisen about the safety of laparoscopy in the treatment of endometrial cancer. Methods: A retrospective multicenter cohort study which included all endometrial cancer (EC) patients who underwent a hysterectomy in Emilia Romagna hospitals from 2000 to 2019. All cases were revised and classified according to the 2009 International Federation of Gynaecology and Obstetrics (FIGO) staging system. The different impacts of the surgical approach on survival were stratified according to the recurrence risk from the 2016 European Society for Medical Oncology (ESMO)–European Society of Gynaecological Oncology (ESGO) classification system. The clinical characteristics and oncological outcome of patients treated by laparoscopy were compared with those treated by laparotomy. Results: A total of 2402 EC patients were included in the study. The use of laparoscopy has increased over the years, reaching 81% of procedures in 2019. Laparoscopy reduced complications and hospital stay. Laparoscopy was preferred to treat low, intermediate, and intermediate/high-risk patients. Laparoscopy showed no adverse effects on overall survival (OS) in any recurrence risk class. Particularly in high-risk EC patients, laparoscopy was associated with an increased OS in comparison with women treated by laparotomy regardless of the use of adjuvant therapy. Conclusions: Laparoscopy should always be chosen to treat EC of any risk class. The goal is to ensure correct treatment and oncological safety regardless of the surgical approach. Full article

Perinatal depression is one of the most common mental illnesses in women. The aim of this study was to assess the association of life stressors, perceived stress, obstetric and neonatal complications, and depressive symptoms in the early postpartum period and to compare these variables in two groups of women (preterm and term deliveries). Methods: A case–control study was conducted among 300 women who gave birth in 2019 at the University of Szeged. Cases included women with preterm deliveries (<37 weeks, n = 100), and the controls included women with term deliveries (≥37 weeks, n = 200). Data were collected during postpartum hospital stays through a self-administered questionnaire (containing validated questionnaires: the Holmes–Rahe Life Stress Inventory, the Perceived Stress Scale (PSS-14), and the Edinburgh Postnatal Depression Scale (EPDS)) and the medical records of women and newborns. A descriptive statistical analysis and logistic regression were used to identify predictors of high EPDS scores (≥10). Results: Perceived stress levels were significantly higher among cases than controls (p < 0.001). Higher perceived stress was associated with a higher risk of depression in cases (OR: 1.31, 95% CI: 1.17–1.48, p < 0.001) and controls (OR: 1.33, 95% CI: 1.21–1.45, p < 0.001), too. Newborn complications were associated with an increased perinatal depression risk in the controls (OR: 2.48, 95% CI: 1.05–5.91; p = 0.039) but not in the cases (OR: 2.79, 95% CI: 0.79–9.85; p = 0.111). It is supposed that premature birth was stressful itself, and women with preterm babies were less sensitive to any complications occurring in their newborns compared to women with term newborns. Neither maternal age, education, nor obstetric complications predicted depressive symptoms. Conclusions: Our findings highlight the impact of maternal perceived stress and newborns’ health status on the risk of developing depression during the early postpartum period. These results emphasize the need for ongoing screening and follow-up measures, especially for women with higher EPDS scores. Full article
