Background: Artificial intelligence (AI) and machine learning (ML) have been reshaping maternal, fetal, neonatal, and reproductive healthcare by enhancing risk prediction, diagnostic accuracy, and operational efficiency across the perinatal continuum. However, no comprehensive synthesis has yet been published. Objective: To conduct a scoping review of reviews of AI/ML applications spanning reproductive, prenatal, postpartum, neonatal, and early child-development care. Methods: We searched PubMed, Embase, the Cochrane Library, Web of Science, and Scopus through April 2025. Two reviewers independently screened records, extracted data, and assessed methodological quality using AMSTAR 2 for systematic reviews, ROBIS for bias assessment, SANRA for narrative reviews, and JBI guidance for scoping reviews. Results: Thirty-nine reviews met our inclusion criteria. In preconception and fertility treatment, convolutional neural network-based platforms can identify viable embryos and key sperm parameters with over 90 percent accuracy, and machine-learning models can personalize follicle-stimulating hormone regimens to boost mature oocyte yield while reducing overall medication use. Digital sexual-health chatbots have enhanced patient education, pre-exposure prophylaxis adherence, and safer sexual behaviors, although data-privacy safeguards and bias mitigation remain priorities. During pregnancy, advanced deep-learning models can segment fetal anatomy on ultrasound images with more than 90 percent overlap compared to expert annotations and can detect anomalies with sensitivity exceeding 93 percent. Predictive biometric tools can estimate gestational age within one week with accuracy and fetal weight within approximately 190 g. In the postpartum period, AI-driven decision-support systems and conversational agents can facilitate early screening for depression and can guide follow-up care. Wearable sensors enable remote monitoring of maternal blood pressure and heart rate to support timely clinical intervention. Within neonatal care, the Heart Rate Observation (HeRO) system has reduced mortality among very low-birth-weight infants by roughly 20 percent, and additional AI models can predict neonatal sepsis, retinopathy of prematurity, and necrotizing enterocolitis with area-under-the-curve values above 0.80. From an operational standpoint, automated ultrasound workflows deliver biometric measurements at about 14 milliseconds per frame, and dynamic scheduling in IVF laboratories lowers staff workload and per-cycle costs. Home-monitoring platforms for pregnant women are associated with 7–11 percent reductions in maternal mortality and preeclampsia incidence. Despite these advances, most evidence derives from retrospective, single-center studies with limited external validation. Low-resource settings, especially in Sub-Saharan Africa, remain under-represented, and few AI solutions are fully embedded in electronic health records. Conclusions: AI holds transformative promise for perinatal care but will require prospective multicenter validation, equity-centered design, robust governance, transparent fairness audits, and seamless electronic health record integration to translate these innovations into routine practice and improve maternal and neonatal outcomes.

Background: Preterm infants and their families face a challenging experience during their stay in the neonatal intensive care unit (NICU). Family-centered care emphasizes the importance of welcoming parents, involving them in their baby’s daily care, and supporting the development of parenting skills. NICU staff should support parents in understanding their baby’s needs and in strengthening the parent–infant bond. Although many tools outline what parents should learn, there is a limited structured framework to monitor their involvement in the infant’s care. Tracking parental participation in daily caregiving activities could support professionals in effectively guiding families, ensuring a smoother transition to discharge. Aims: The aim of this study was to evaluate the adherence to and effectiveness of a structured tool for parental involvement in the NICU. This tool serves several key purposes: to track the progression and timing of parents’ autonomy in caring for their baby, to support parents in building caregiving competencies before discharge, and to standardize the approach of NICU professionals in promoting both infant care and family engagement. Methods: A structured template form for documenting parental involvement (“together TO-CARE template”, TTCT) was integrated into the computerized chart adopted in the NICU of Modena. Nurses were asked to complete the TTCT at each shift. The template included the following assessment items: parental presence; type of contact with the baby (touch; voice; skin-to-skin); parental involvement in care activities (diaper changing; gavage feeding; bottle feeding; breast feeding); and level of autonomy in care (observer; supported by nurse; autonomous). We evaluated TTCT uploaded data for very low birth weight (VLBW) preterm infants admitted in the Modena NICU between 1 January 2023 and 31 December 2024. Staff compliance in filling out the TTCT was assessed. The timing at which parents achieved autonomy in different care tasks was also measured. Results: The TTCT was completed with an average of one entry per day, during the NICU stay. Parents reached full autonomy in diaper changing at a mean of 21.1 ± 15.3 days and in bottle feeding at a mean of 48.0 ± 22.4 days after admission. The mean length of hospitalization was 53 ± 38 days. Conclusions: The adoption of the TTCT in the NICU is feasible and should become a central component of care for preterm infants. It promotes family-centered care by addressing the needs of both the baby and the family. Encouraging early and progressive parental involvement enhances parenting skills, builds confidence, and may help reduce post-discharge complications and readmissions. Furthermore, the use of a standardized template aims to foster consistency among NICU staff, reduce disparities in care delivery, and strengthen the support provided to families of preterm infants.

Background: Prematurely born newborns with low birth weight constitute a group of patients who require special care from the first days of life. Prematurity and low birth weight affect about 13.4 million infants. Risk factors include placental disorders but also factors related to the mother, such as smoking, alcohol drinking, drug use, malnutrition, or certain diseases. It is imperative to educate women of reproductive age (15–49) about the basic factors influencing embryonic development, such as oral health, diet, medicine intake, and harmful habits. Even though most women are aware of the negative impact of harmful habits on the fetus, still too little attention is paid to oral health in pregnant women. Poor oral health may influence the well-being of the future mother, as well as of the child. Therefore, women of reproductive age and those who are pregnant must have adequate knowledge on this subject. The aim of this study was to assess the knowledge of Polish women of reproductive age (15–49) regarding oral health during pregnancy, including the impact of dental treatment, oral hygiene, and maternal oral conditions on pregnancy outcomes and the health of the newborn. Materials and Methods: This was a cross-sectional study of 508 women, in the reproductive age, whose age ranged from 18 to 49 years old. The surveys were conducted from April 2020 to November 2020. The questionnaire was originally developed based on the available literature and consisted of seven sections: basic information, general health and habits, pregnancy status and dental care, knowledge of treatment options during pregnancy, oral health status and its association with the risk of preterm birth, prematurity and the child’s oral health, and breastfeeding and oral development. Results: After excluding incomplete questionnaires, a total of 499 questionnaires were included in the analysis. Women participating in the study had a fairly good understanding of the impact of oral health on the fetus and the role of breastfeeding in the development of the stomatognathic system (from 50% to 70% correct answers). However, even though most respondents had completed higher education (344/68.94%), their knowledge of oral health, preterm birth, and low birth weight was very limited (including the impact of inflammation on the intrauterine development of the child or bacteria and transfer across the placenta). In these sections, the percentage of correct answers ranged from less than 20% to 50%. When analyzing knowledge by age, education, number of births, and place of residence, the highest levels of knowledge were observed among respondents with higher education, particularly those aged 27–32. Conclusions: Respondents had a fairly good understanding of the general impact of oral health during pregnancy and recognition of the importance of breastfeeding for infants. However, their knowledge about the impact of bacteria and inflammation in the mother’s oral cavity on prematurity and low birth weight was limited. Therefore, educating women of reproductive age and pregnant women on this topic is essential, as it may help reduce the adverse consequences of prematurity. Full article

Pulmonary hemorrhage (PH) is a life-threatening complication predominantly affecting preterm infants, particularly those with very low birth weight (VLBW) and fetal growth restriction (FGR). Typically occurring within the first 72 h of life, PH is characterized by acute respiratory deterioration and significant morbidity and mortality. This review synthesizes current evidence on the multifactorial pathogenesis of PH, highlighting the roles of immature pulmonary vasculature, surfactant-induced hemodynamic shifts, and left ventricular diastolic dysfunction. Key risk factors include respiratory distress syndrome (RDS), hemodynamically significant patent ductus arteriosus (hsPDA), sepsis, coagulopathies, and genetic predispositions. Diagnostic approaches incorporate clinical signs, chest imaging, lung ultrasound, and echocardiography. Management strategies are multifaceted and include ventilatory support—particularly high-frequency oscillatory ventilation (HFOV)—surfactant re-administration, blood product transfusion, and targeted hemostatic agents. Emerging therapies such as recombinant activated factor VII and antifibrinolytics show promise but require further investigation. Preventive measures like antenatal corticosteroids and early indomethacin prophylaxis may reduce incidence, particularly in high-risk populations. Despite advancements in neonatal care, PH remains a major contributor to neonatal mortality and long-term neurodevelopmental impairment. Future research should focus on individualized risk stratification, early diagnostic tools, and optimized treatment protocols to improve outcomes. Multidisciplinary collaboration and innovation are essential to advancing care for this vulnerable population. Full article

Objectives: Pulmonary hypertension and hemodynamically significant PDA (hsPDA) involve seemingly opposite physiological features—decreased pulmonary blood flow and pulmonary overcirculation, respectively—but the literature demonstrates variable respiratory consequences in association with each of these morbidities. The aim of this study is to evaluate whether the two factors representing pulmonary circulation provide different contributions to respiratory outcomes in preterm infants with and without pulmonary hypoplasia. Methods: The medical records of preterm very low birth weight (VLBW) infants admitted to our unit during the study period from January 2013 to December 2020 were retrospectively reviewed. Preterm VLBW infants were divided into groups according to the presence of presumed pulmonary hypoplasia (PPH). Multivariable logistic regression analysis was performed to assess the association of PPH and pulmonary hypertension or delayed PDA closure with in-hospital outcomes. Results: Postnatal age at final treatment for PDA was significantly later [median 33 vs. 19 days, p = 0.025] in the PPH group. Multivariable analysis indicated that early pulmonary hypertension was significantly associated with neonatal death [aOR (95%CI) 11.575 (2.988–44.833) for no-PPH vs. 9.981 (1.334–74.647) for PPH]. Delayed PDA closure was associated with increased odds of adverse respiratory and composite outcomes [aOR (95%CI) 4.929 (1.613–15.055) and 3.320 (1.048–10.515), respectively] but decreased odds of neonatal death in the no-PPH group. However, Cox proportional hazards models did not demonstrate statistically significant associations for PPH, early pulmonary hypertension, or delayed PDA closure with mortality, likely due to time-varying effects and the absence of death events in the subgroup of infants with both PPH and delayed PDA closure. Conclusions: PPH is associated with a higher prevalence of air leak syndrome and pulmonary hypertension. Delayed PDA closure exerts different effects on respiratory outcomes in preterm VLBW infants with and without PPH. Although early pulmonary hypertension appears to be a key circulatory factor contributing to neonatal death, its effect may vary over time. These findings underscore the importance of accounting for time-dependent effects when interpreting pulmonary circulatory risk factors in clinical practice. Full article

Background: Human cytomegalovirus (HCMV) is the leading cause of congenital and acquired viral infections in newborns. While acquired infections are often asymptomatic, premature infants—especially those born before 30 weeks of gestation or with a very low birth weight (<1500 g)—are at an increased risk for severe infections. These can manifest as thrombocytopenia, liver failure, sepsis-like symptoms, and, in rare cases, death. HCMV is transmitted through various human secretions, including breast milk, which is the optimal feeding method for premature infants. Methods: We present five premature neonates, born between 23 and 26 weeks of gestation, each with a distinct clinical presentation of acquired HCMV infection. Results: All infants tested negative for congenital CMV infection via molecular urine testing within the first three weeks of life. Acquired infection was diagnosed between the second and third month of life, with symptoms such as septic shock, persistent thrombocytopenia, and signs of liver failure. Each infant received antiviral treatment along with regular viral load monitoring. Unfortunately, one patient died due to complications of prematurity. The remaining infants were discharged and continue to receive follow-up care in an outpatient clinic. Conclusions: These cases of postnatally acquired CMV infection aim to increase awareness of its highly heterogeneous and nonspecific clinical presentation, which may result in an incorrect, delayed, or concealed diagnosis. Currently, there are no clear guidelines on how to manage the presence of the virus in maternal breast milk, particularly for premature infants. It should be recommended to perform a molecular CMV test in all breast-fed preterm infants who present with sepsis-like symptoms, thrombocytopenia, liver failure, or other organ involvement. In case of a confirmed aCMV diagnosis, appropriate treatment should be introduced. Full article

Background/Objectives: To identify the risk factors and clinical outcomes of persistent pulmonary hypertension of the newborn (PPHN) in very low birth weight (VLBW) infants in a resource-limited setting. Methods: We conducted a 1:4 matched case–control study in a Thai neonatal unit between 2014 and 2023. Neonates born at a gestational age (GA) < 32 weeks and with a birth weight (BW) < 1500 g were included. Neonates who died in the delivery room or had major congenital anomalies were excluded. Matching was based on GA, BW, year of birth, and endotracheal intubation at birth. Conditional logistic regression analysis was performed. Results: Over the 10-year study period, the incidence of PPHN among VLBW neonates was 4.6% (31/667). After matching, there were 31 cases and 124 controls. In univariable analysis, PPHN was significantly associated with lower 1 min and 5 min Apgar scores; however, no significant association remained in multivariable analysis. PPHN was significantly associated with composite adverse outcomes—including mortality and major morbidities (adjusted odds ratio [aOR] = 7.51, 95% confidence interval [CI]: 2.41–23.40), mortality alone (aOR = 2.88, 95% CI: 1.06–7.63), major morbidities (aOR = 2.99; 95% CI: 1.29–6.95), and severe neurological injury (aOR = 4.44, 95% CI: 1.56–12.59). Daily hospital costs were also higher in PPHN cases, with an average increase of 97.1 USD. Conclusions: In VLBW infants, PPHN was associated with a lower Apgar score and surfactant administration. PPHN was significantly linked to adverse outcomes, particularly mortality, major morbidities, and severe neurological injury. Full article

Background: Respiratory distress syndrome (RDS) is a frequent cause of invasive respiratory support. Our study aims to assess end-expiratory lung impedance (EELZ) and DeltaZ changes post-suction using electrical impedance tomography. Methods: Very low birth weight infants with gestational ages less than 32 weeks under conventional mechanical ventilation with an open endotracheal suction system were included in this study. Data was evaluated at four time periods: immediately after the completion of suctioning and at 1, 5 and 10 min marks post-suction. Results: Sixteen patients participated in this study, during which a total of 31 suctioning events were recorded. There were no significant hypoxemic events during the analyzed timeframe. Over a 10 min period following suction, there was a consistent change in EELZ and DeltaZ, with EELZ decreasing and DeltaZ increasing accordingly (p < 0.001). Conclusions: Our study demonstrated that EELZ and DeltaZ changes persist even 10 min after suctioning using an open endotracheal suction system. Full article

As the limit of viability is extended to lower gestational ages, neonatologists caring for preterm infants must discover the optimal nutritional combination to support postnatal growth. It has been well established that introducing protein soon after birth is associated with improved short-term growth at 36 weeks postmenstrual age and neurodevelopment. However, it remains unclear what the optimal level of protein is for parenteral nutrition at various gestational ages. Several studies have shown possible adverse effects of high-protein delivery in very low birth weight infants. Inborn errors in amino acid metabolism also caution us that higher levels of specific amino acids can harm the growing brain. Full article

The complications observed in preterm infants are largely attributable to underdeveloped organ systems and inadequate nutritional stores at birth. Insufficient nutritional support can further exacerbate persistent sequelae, such as bronchopulmonary dysplasia (BPD), metabolic bone disease of prematurity (MBDP), and retinopathy of prematurity (ROP). As a result, clinicians have collaborated to develop optimal nutrition strategies for preterm neonates. However, these clinical nutrition plans may be hindered by several factors, including fluid restrictions due to patent ductus arteriosus (PDA) and delayed enteral nutrition following necrotizing enterocolitis (NEC). Modified strategies for specific conditions can help prevent further deterioration, but inadequate nutritional support may limit organ growth and contribute to additional complications. Achieving an optimal balance between nutritional support and managing specific medical conditions varies across institutions. In addition to fluid balance and energy intake, supplementary nutrition—such as vitamins and probiotics—plays a crucial role in disease prevention. Drawing on recent evidence and our clinical experiences with neonatal nutritional strategies, this review article summarizes the specialized nutritional management required for preterm neonates with conditions such as BPD, NEC, MBDP, PDA, and ROP.

Background: Necrotizing enterocolitis is the leading gastrointestinal cause of morbidity and mortality in neonatal intensive care units. Despite advancements in neonatal care, the incidence of NEC remains unchanged. This study evaluated trends in NEC incidence and severity over the past decade and identified associated risk factors in our NICU population. Methods: This was a retrospective cohort study comparing the prevalence and severity of NEC among VLBW infants born before 32 weeks of gestation across the following two periods: 2012–2016 and 2017–2021. Clinical data were extracted from medical records, with NEC diagnosis and grading based on the modified Bell’s criteria. Results: A total of 299 infants were included. Those born in the later period were significantly more preterm and had lower birth weights. While the overall NEC incidence increased in the later cohort, the rate of surgical NEC was lower. Logistic regression identified hemodynamic instability requiring pressor support, late-onset sepsis, and earlier gestational age as significant risk factors for NEC. Conclusions: Although the incidence of NEC was higher in the later cohort, its severity was lower compared to the earlier cohort. These findings suggest that advancements in neonatal care and feeding protocols may contribute to improved outcomes. Early NEC stages may represent alternative intestinal or systemic conditions warranting further research for better diagnosis. Full article

Background: The diagnosis of hemodynamically significant patent ductus arteriosus (hsPDA) occurs in 55% of very low birth weight (VLBW) preterm infants. There is no agreement on the best approach to ensure a quick hsPDA closure. Drug treatment of hsPDA fails in approximately 20% of cases with an increasing risk of prolonged ventilation, BPD, and NEC, as well as the need for surgical duct ligation. This study aims to highlight the efficacy of ibuprofen versus acetaminophen in the case of a second cycle of medical therapy after the failure of the first pharmacological approach for hsPDA closure. Methods: Every VLBW infant admitted to our NICU and treated for hsPDA was included in our retrospective research. Information about the clinical course, hsPDA diagnosis and treatment, and common complications associated with preterm birth was collected. A comparison was made between patients treated with acetaminophen or ibuprofen to assess effectiveness in hsPDA closing. Results: A total of 286 VLBW infants were included. First-course ibuprofen was effective in 87 of 115 infants (75.7%) treated, acetaminophen in 138 of 171 (80.7%). Second-course therapy with ibuprofen was effective in 62.5% of the patients, while acetaminophen was effective in 69.2%. No statistically significant difference was observed in the first-course and second-course success rates. Conclusions: This study confirms that acetaminophen is not inferior to ibuprofen in the closure of hsPDA in VLBW infants. Our data demonstrate that a second course of medical therapy after the failure of the first course could help close the majority of hsPDA cases without surgery. Full article

Background: Human milk (HM) offers critical short- and long-term benefits for preterm and very low birth weight (VLBW) infants. In 2021, a human milk bank (HMB) was established at the IRCCS Giannina Gaslini Institute, aiming to improve HM feeding rates in this vulnerable population. Methods: We retrospectively analyzed feeding data from 442 VLBW infants (BW < 1500 g) admitted between 2018 and 2024. Data were drawn from the Vermont Oxford Network and Italian Neonatal Network registries. Feeding modalities—exclusive HM, infant formula milk (IM), and mixed feeding (MF)—were recorded and analyzed before and after HMB introduction. Results: Before 2021, MF was predominant, with exclusive HM rates below 10%. Following HMB implementation, exclusive HM feeding increased significantly, reaching 47.2% in 2024 (p < 0.0001). Regression analysis showed a positive trend for HM (+4.84%/year, p = 0.05), and a declining trend for IM (−1.96%/year) and MF (−2.88%/year). Projections suggest HM rates may exceed 58% by 2030. Conclusions: The introduction of the HMB was associated with a significant shift in feeding practices, increasing HM use and reducing IM exposure among VLBW infants. These findings underscore the importance of institutional strategies such as donor milk availability, lactation support, and maternal education in optimizing neonatal nutrition. Ongoing efforts are essential to sustain and extend these improvements beyond NICU discharge, ensuring the long-term benefits of human milk for preterm infants. Full article

Background/Objectives: Bronchopulmonary dysplasia (BPD) and retinopathy of prematurity (ROP) affect the prognosis of preterm infants, and their coexistence is a risk factor for poor long-term outcomes in very low-birth-weight infants. However, there has been limited in-depth assessment of common and independent risk factors for BPD and ROP within the same cohort. Therefore, we aimed to investigate the risk factors for BPD and ROP in very low-birth-weight infants born at ≤32 weeks of gestation and to explore the interaction between these two diseases. Methods: The participants were divided into four groups: BPD+ROP+, BPD-ROP-, BPD+ROP-, and BPD-ROP+. Gestational age, birth weight, maternal pregnancy complications, birth and postnatal diseases, and treatment conditions were compared among the groups. Subsequently, univariate and multivariate binary logistic regression analyses were conducted to explore the independent risk factors for BPD and ROP. Results: Common risk factors of BPD and ROP included gestational age and prolonged oxygen therapy. The multivariate analysis revealed that gestational age (OR: 4.44; 95% CI: 3–6.57), intubation resuscitation (OR: 2.35; 95% CI: 1.09–5.05), mechanical ventilation duration ≥ 7 days (OR: 1.01; 95% CI: 1.01–1.01), and prolonged total oxygen therapy (OR: 3.13; 95% CI: 1.28–7.64) were independent risk factors for BPD. Additionally, gestational age (OR: 0.66; 95% CI: 0.54–0.81) and prolonged oxygen therapy (OR: 1.02; 95% CI: 1–1.03) were independent risk factors for ROP. Conclusions: The proper control of the duration and concentration of oxygen therapy, along with the minimization of mechanical ventilation time, is crucial for reducing the incidence of both BPD and ROP.
