Antiphospholipid syndrome (APS) is an autoimmune disorder associated with thrombotic events and adverse obstetric outcomes, particularly in its obstetric form (OAPS). Affecting approximately 0.5% of the population, APS is a leading contributor to recurrent pregnancy loss (RPL), preeclampsia (PE), and fetal growth restriction ((FGR). Despite advancements in understanding its pathophysiology and management, optimal treatment strategies for APS in pregnancy remain challenging and require systematic evaluation. This review synthesizes current evidence on APS mechanisms, diagnostic criteria, and therapeutic interventions, with a focus on maternal and fetal outcomes in OAPS. A comprehensive search of PubMed, was conducted to identify studies exploring APS pathogenesis, diagnostic standards, and treatment efficacy in obstetric settings. Inclusion criteria prioritized randomized controlled trials, cohort studies, and systematic reviews with a clear focus on APS and pregnancy. The review confirmed that APS current accepted pathogenesis is governed by a “two-hit” model, where antiphospholipid antibodies (aPLs) initiate endothelial damage, culminating in thrombosis and placental insufficiency. Epidemiological analysis underscores the prevalence and severity of APS in obstetric contexts, with lupus anticoagulant (LA) emerging as a significant predictor of adverse outcomes. Evidence supports the use of low-dose aspirin (LDA) and heparin to reduce miscarriage rates, while adjunctive treatments, such as hydroxychloroquine (HCQ), have shown promise in improving live birth rates and reducing preterm delivery in high-risk cases. Emerging therapies, including tumoral necrosis factor (TNF-alpha) inhibitors and nitric oxide modulators, may offer additional benefits in refractory cases. APS remains a critical determinant of adverse pregnancy outcomes, necessitating precise diagnostic criteria and tailored management approaches. This systematic review emphasizes the importance of individualized therapeutic regimens to optimize maternal and fetal health in OAPS and highlights areas for future research, particularly regarding novel pharmacological approaches. Further studies are essential to refine treatment protocols and improve clinical guidelines for managing APS in pregnancy.

This meta-analysis assessed short-term outcomes after using human milk-derived fortifiers (HMFs) compared with bovine milk fortifiers (BMFs) in preterm infants fed an exclusive human milk (HM) diet, either mother’s own milk (MOM) or donor human milk (DHM). We searched PubMed, Embase, Google Scholar, CENTRAL and CINHAL between January 2015 and August 2023 for studies reporting outcomes in infants with ≤28 weeks gestation and/or birthweight ≤ 1500 g on an exclusive human milk diet fortified with HMF versus BMF. The primary outcomes were death and NEC (stage ≥ 2). Four studies with a total of 681 infants were included. Mortality was significantly lower in infants fed with an HM-HMFs diet (four studies, 681 infants; RR = 0.50, 95% CI = 0.26–0.94; p = 0.03; I² = 0%), NEC was similar between the two groups (four studies, 681 infants; RR = 0.48, 95% CI = 0.20–1.17; p = 0.11; I²= 39%). BPD was higher in the HM-BMFs group (four studies, 663 infants; RR = 0.83, 95% CI = 0.69–1.000; p = 0.05, I² = 0%), although not statistically significant. No differences were found for sepsis (RR = 0.97, 95% CI = 0.66–1.42; p = 0.96; I² = 26%) or combined ROP (four studies, 671 infants; RR = 0.64, 95% CI = 0.53–1.07; p = 0.28; I² = 69%). An HM-HMFs diet could possibly be associated with decreased mortality with no association with NEC, BPD, sepsis, or ROP. This meta-analysis was limited by the small number of studies included. However, the results should not be refuted for this reason as they provide an impetus for subsequent clinical trials to assess the observed associations.

Background and Objective: The effects of neonatal hypoglycemia on the developing brain are well known, resulting in poor neurological outcomes. We aimed to perform an updated meta-analysis on neonatal hypoglycemia, the severity of hypoglycemia, and the associated neurodevelopmental outcomes from infancy to adulthood. Methods: A systematic literature search was conducted from inception until March 2024, using the PubMed, CINAHL, Embase, and the CENTRAL databases. Randomized/quasi-randomized trials and observational studies that evaluated at least one of the pre-specified outcomes were included. A random-effects model meta-analysis was performed to yield the pooled OR and its 95% CI for each outcome due to the expected heterogeneity in the studies. The study findings were reported as per the PRISMA guidelines. Neurodevelopmental impairment (NDI), cognitive impairment, and visual-motor or visual impairment were the primary outcomes. Results: A total of 17 studies (19 publications) were included in the final analysis. NDI, as defined by authors, was significantly higher in early- (OR = 1.16; 95% CI = 1.11–1.43) and mid-childhood (OR = 3.67; 95%CI = 1.07–12.2) in infants with neonatal hypoglycemia. ‘Any cognitive impairment’ was significantly more common in infants with neonatal hypoglycemia (OR = 2.12; 95%CI = 1.79–2.52). Visual-motor impairment (OR = 3.33; 95%CI = 1.14–9.72) and executive dysfunction (OR = 1.99; 95%CI = 1.36–2.91) were also more common in the hypoglycemic group. No difference in the incidence of epilepsy, motor impairment, emotional-behavioral problems, or hearing impairment were noted. Certainty of evidence was adjudged as ‘low’ to ‘very low’ for most outcomes. The severity of hypoglycemia was studied at different intervals, with NDI more common with a blood glucose interval between 20 and 34 mg/dL (1.1–1.9 mmol/L). Conclusions: Low-quality evidence from large observational studies finds a significant association with hypoglycemia in the early neonatal period and long-term neurodevelopmental problems. Additional studies with long enough follow-up are paramount to determine the cut-off concentration and to quantify the impact beyond the infancy period.

Background: International studies have reported conflicting data about the effects of COVID-19 pandemic policy measures on maternal and neonatal health. A major impact was reported on stillbirth and prematurity. The published literature suggests that the economic setting influenced the effects of imposed mitigation measures with a more severe effect in low-income countries.Objectives: Our objective is to compare pregnancy outcomes at the only tertiary Maternity Hospital in Bihor County-Romania before and during the COVID-19 pandemic. This study aims to observe and document differences in perinatal outcomes across these periods, without inferring direct causation related to the pandemic or its associated restrictions.Materials and methods: We used data from the registries of Public Health Services Bihor to conduct a retrospective cohort analysis of preterm births and stillbirths during the COVID-19 pandemic in Bihor County, Romania. Pregnancy outcomes were compared between the pandemic period (March 2020–February 2022) to the corresponding historical pre-COVID-19 period (March 2018–February 2020). Maternal socio-demographic variables and neonatal characteristics of these periods were also examined.Results: The COVID-19 pandemic period was associated with an increase in the stillbirth rate (RR: 1.53, 95% CI, 1.05–2.23). Preterm birth was significantly impacted during this period and showed changes when analyzing gestational age (RR: 0.88, 95% CI, 0.79–0.96) or birth weight (RR: 0.91, 95% CI, 0.82–1.00). The main cause of stillbirth was intrauterine asphyxia due to placental causes (67.6%) or cord pathology (12.6%), the most frequently encountered maternal pathology was cardiovascular (28.3%) or infectious (21.7%). Our study revealed no significant changes in terms of maternal and neonatal characteristics during the two-year pandemic period.Conclusions: Lockdown restrictions in Bihor County, Romania were associated with an increase in stillbirths, whilst preterm birth rate decreased. This raises concerns about whether pandemic policy measures may have led to a failure in identifying and offering proper care for pregnant women who were more likely to experience an antepartum loss. Further studies across the globe are needed in order to integrate comparable data that will help develop adequate protocols and policies for protecting maternal and child health during the next pandemic that will follow.

Background and Objectives: Preterm birth and stillbirth are primary adverse pregnancy outcomes. Research during the COVID-19 pandemic revealed reductions in preterm birth in some countries, while stillbirth rates increased or remained unchanged. These findings suggest the presence of preventable risk factors associated with changes in physical activity and lower exposure to community-acquired infections due to lockdown measures, altered social interaction patterns or reduced access to antenatal care. Assessing seasonal variation may offer insights into whether lifestyle changes during the COVID-19 lockdown period influenced preterm birth rates. Materials and Methods: This retrospective cohort study used data from the electronic medical records of Bihor and Sibiu counties. Preterm deliveries (<37 weeks) and stillbirths during the COVID-19 pandemic (2020 and 2021) were compared with the corresponding pre-pandemic (2018 and 2019) and post-pandemic (2022 and 2023) period. Preterm birth rates during summer and winter in the pre-pandemic, pandemic, and post-pandemic years were analyzed. A comparison with rates during strict lockdown was made. Results: Out of 52,021 newborn infants, 4473 were born preterm. Preterm birth rates remained stable across all three periods (p = 0.13), and no significant seasonal pattern was identified (p = 0.65). In contrast, stillbirth rates increased notably during the strict lockdown period, with the median incidence almost doubling compared to other periods (0.87%, p = 0.05), while remaining unchanged during the rest of the pandemic (p = 0.52). Conclusions: Our study found that preterm birth rates remained unaffected by the pandemic and lockdown periods, while stillbirths increased significantly during the strict lockdown. These findings highlight the importance of maintaining access to timely antenatal care during public health emergencies to prevent adverse perinatal outcomes.

Background: Preeclampsia is a major cause of maternal and perinatal morbidity, characterized by placental dysfunction and angiogenic imbalance. The soluble fms-like tyrosine kinase-1-to-placental growth factor (sFlt-1/PlGF) ratio has emerged as a promising biomarker for preeclampsia; however, its prognostic value for maternal and neonatal outcomes remains incompletely defined. Methods: This retrospective cohort study included 320 pregnant women, of whom 68 were diagnosed with preeclampsia, and 252 served as non-preeclamptic controls. Maternal serum sFlt-1 and PlGF levels were measured after 20 weeks of gestation at the time of clinical evaluation for suspected hypertensive disorders of pregnancy. Group comparisons, effect size analysis, receiver operating characteristic (ROC) curve analysis, and multivariable regression models were used to assess diagnostic performance and associations with maternal and neonatal outcomes. Results: The sFlt-1/PlGF ratio was significantly higher in women with preeclampsia compared with non-preeclamptic pregnancies (58.5 ± 17.3 vs. 34.6 ± 19.0; p < 0.001; Cohen’s d = 1.31). ROC analysis demonstrated good discriminative ability for preeclampsia (AUC = 0.81, 95% CI: 0.75–0.87), with a high negative predictive value. Increasing sFlt-1/PlGF values were independently associated with earlier gestational age at delivery, lower birth weight, reduced Apgar (Appearance, Pulse, Grimace, Activity, and Respiration) score, and a higher likelihood of neonatal intensive care unit admission. Conclusions: The sFlt-1/PlGF ratio is a robust biomarker for preeclampsia, providing both diagnostic discrimination and prognostic information regarding maternal and neonatal outcomes. Its integration into clinical practice may support clinical risk awareness when interpreted in the context of standard clinical evaluation and support informed decision-making in pregnancies with suspected or confirmed preeclampsia.
