Clinical practice guidelines for the diagnosis and treatment of anemia of prematurity (2025)

Anemia of prematurity (AOP) is a multifactorial condition associated with congenital iron deficiency, low erythropoietin levels, a short lifespan of red blood cells, and iatrogenic blood loss. AOP is a common complication in premature infants that can adversely affect growth, development, and long-term neurocognitive outcomes. To standardize the diagnosis and treatment of AOP, the Neonatal Clinical Practice Guidelines Expert Committee and the Neonatal Evidence-Based Medicine Group of the Commission of Neonatal Medicine of the Cross-Strait Medical and Health Exchange Association, along with the Editorial Office of the Chinese Journal of Contemporary Pediatrics, have developed the "Clinical practice guidelines for the diagnosis and treatment of anemia of prematurity (2025)", based on the World Health Organization's handbook for guideline development and the formulation/revision principles of Chinese clinical practice guidelines. This guideline addresses eight clinical issues related to AOP, including risk factors, early identification, etiological diagnosis, diagnostic criteria, early prevention, transfusion therapy, strategies to improve prognosis, and post-discharge follow-up. It presents 29 recommendations formed from current evidence and expert consensus, aiming to provide guidance and decision-making support for healthcare professionals in the diagnosis and treatment of AOP.

Content Validity for the Checklist of NICU Caregiver Behaviors.

To update and establish content validity for the Checklist of NICU Caregiver Behaviors. Structured literature review and Delphi analysis. Neonates born prematurely or who are sick in the NICU are frequently exposed to harmful stimuli that can affect brain development and result in adverse neurodevelopmental outcomes. In response to this risk, NICU caregiving now encompasses protecting and promoting neurodevelopment to affect long-term outcomes for neonates and their families. Developmentally supportive care (DSC) includes internationally recognized best practices for the care of neonates in the NICU. Implementation and operationalization of DSC is a priority for neonatology. Although evidence-supported guidelines exist for effective DSC strategies in the NICU, no validated tool exists to support implementation at the point of care. Nine expert reviewers from the United States and India including four occupational therapists, one nurse practitioner, one clinical nurse specialist, and three neonatal medicine specialists. The Checklist of NICU Caregiver Behaviors had been updated based on a structured review of the evidence. The updated checklist was then shared with a group of professionals with DSC expertise who provided further recommendations using a modified Delphi survey process. The project yielded the current NICU Caregiver Behavior Checklist. Expert reviewers provided 53 actionable recommendations in Round 1 and 18 actionable recommendations in Round 2 to support clarity and use of the tool. In response, the NICU Caregiver Behavior Checklist was reformatted as a collection of five checklists, each representing a core measure of DSC; the introduction section was expanded; language was broadened; and clarifications were provided to promote observations of target behaviors and allow for more site-specific recommendations and assessments. This evidence-based tool can be used as part of DSC education, as a self-assessment tool, and as a measure of NICU caregivers' use and quality of DSC.

Hydrogen gas inhalation ameliorates glomerular enlargement after hypoxic-ischemic insult in asphyxiated piglet model

Acute kidney injury (AKI) has been reported to occur in 30–70% of asphyxiated neonates. Hydrogen (H2) gas became a major research focus in neonatal medicine after the identification of its robust antioxidative properties. However, the ability of H2 gas to ameliorate AKI is unknown. We examined histopathological injuries in the piglet renal cortex on day 5 after a hypoxic-ischemic (HI) insult and if H2 gas can alleviate kidney injuries. Twenty piglets were divided into three groups: no insult (Control, n = 6), HI insult alone (HI, n = 8), and HI insult with H2 gas ventilation (HI-H2, 2.1–2.7% for 24 h, n = 6). The total glomerular cell count was significantly higher in the HI group than in the other groups, with no difference between the HI-H2 and control groups. Proximal tubular lumen narrowing was significantly increased in the HI group versus control, but not in the HI-H2 group. In this piglet model, glomerular enlargement with an increase in glomerular cell number due to tubular lumen narrowing was observed on day 5 after HI insult. H2 gas effectively suppressed this glomerular cell increase and tubular lumen narrowing.

Moving on from clinical animal-derived surfactants to peptide-based synthetic pulmonary surfactant.

Research on lung surfactant has exerted a great impact on newborn respiratory care and significantly improved survival and outcome of preterm infants with respiratory distress syndrome (RDS) due to surfactant deficiency because of lung immaturity. Current clinical, animal-derived, surfactants are among the most widely tested compounds in neonatology However, limited availability, high production costs, and ethical concerns about using animal-derived products constitute important limitations in their universal application. Synthetic lung surfactant offers a promising alternative to animal-derived surfactant by providing improved consistency, quality and purity, availability and scalability, ease of production and lower costs, acceptance, and safety for the treatment of neonatal RDS and other lung conditions. Third-generation synthetic surfactants built around surfactant protein B (SP-B) and C (SP-C) peptide mimics stand at the forefront of innovation in neonatal pulmonary medicine, while nasal continuous positive airway pressure (nCPAP) has become the standard non-invasive respiratory support for preterm infants. nCPAP can prevent the risk of chronic lung disease (bronchopulmonary dysplasia) and reduce lung injury by avoiding intubation and mechanical ventilation, is a relatively simple technique and can be initiated safely and effectively in the delivery room. Combining nCPAP with noninvasive, preferably aerosol, delivery of synthetic lung surfactant promises to improve respiratory outcomes for preterm infants, especially in low-and-middle income countries.

Cotoneaster Side Effects Following the Treatment of Neonatal Jaundice

Background: There has been significant interest in using Cotoneaster for treating jaundice or elevated bilirubin levels in newborns, and it has, in many cases, replaced phototherapy in herbal medicine. However, using these compounds to treat hyperbilirubinemia can lead to complications in neonates, potentially resulting in morbidity and even death. Objectives: This study examined the side effects of Cotoneaster consumption in jaundiced neonates admitted to the Children’s Medical Center between 2021 and 2022. Methods: We conducted a cross-sectional study involving healthy neonates who consumed Cotoneaster following treatment for neonatal jaundice and subsequently experienced complications. The data were recorded using pre-prepared questionnaire forms. Results: The most common complications following Cotoneaster derivatives were exaggerated hyperbilirubinemia, dehydration, and poor feeding. Conclusions: Given the sensitivity of neonates, the treatment of jaundice in babies should be approached with caution and supported by extensive studies. The use of herbal medicines in neonates remains questionable due to associated complications.

Post-traumatic stress disorder in mother’s of children hospitalized in the neonatal intensive care

Background: The progress of neonatal intensive care units has notably enhanced the chances of survival for infants. Despite this, post-traumatic stress disorder (PTSD) in mothers of neonates receiving care in the Neonatal Intensive Care Units (NICU) remains a widely underestimated issue. Aims and objectives: Our objective was to pinpoint the possible risk factors contributing to the development of post-traumatic stress disorder in mothers of neonates receiving care in the NICU. Methods: A prospective, descriptive study was carried out at the Mohamed V Moroccan Military teaching hospital over a 1-year period from January 1st, 2023, to December 31st, 2023, concentrating on neonatal medicine and resuscitation. Mothers were interviewed, and the presence of PTSD after preterm birth and NICU admission was assessed using the Clinician Administered PTSD Scale (CAPS) at 28–30 days following NICU admission or at the time of discharge. Results: The findings revealed that mothers of premature infants displayed more stress symptoms compared to mothers of full-term newborns. Through multivariate analysis, we observed that the gestational age of newborns admitted to the NICU significantly ( p = 0.001) influenced the occurrence of PTSD. Conclusion: Post-traumatic stress disorder in mothers of preterm newborns is a pathological condition that demands proper management from the very first days after birth. The NICU environment remains a significant risk factor for PTSD.

67 A population-based cohort study of endocrine outcomes within the first 5 years of life in children born preterm

Abstract Background Preterm birth (<37 weeks’ gestational age [GA]) occurs in 8% of live births in Canada. While advancements in neonatal medicine have led to increased survival in preterm births, infants born preterm continue to sustain short- and long-term health sequelae. There is paucity of large population studies evaluating childhood health care outcomes, including endocrine-related outcomes, in recent birth cohorts. Objectives To evaluate the rates of endocrine conditions during the first 5 years of life in children born preterm and term. Design/Methods The study cohort included liveborn infants at 22-44 weeks’ GA in British Columbia, Canada between 2004-2014. Follow-up data to December 2019 included linked health services use information from four BC provincial databases (perinatal database, hospitalizations, outpatient services, and outpatient prescriptions). Rates of outcomes were compared by GA at birth (37-44 weeks reference category) using robust Poisson regression. Results There were 455,960 children included in this study with 42,820 (9.4%) born at <37 weeks GA. Results are summarized in Table 1 and Table 2. Compared to children born at 37-44 weeks’ gestations, infants born at 36 weeks’ gestation or younger have an increased rate of thyroid disorders between 0 months and 5 years (rate ratio [RR]: 1.45, 95% confidence interval [CI]: 0.78-2.43; RR: 1.83, 95% CI 1.51-2.20; RR: 1.41 95% CI 1.26-1.57 for 22-27 weeks, 28-33 weeks and 34-36 weeks GA, respectively). Similarly, infants born at 36 weeks’ gestation or younger have a higher rate of conditions in growth and development (RR: 3.05, 95% CI: 0.76-7.96; RR: 3.20, 95% CI 2.04-4.76; RR: 1.42 95% CI 1.02-1.94 for 22-27 weeks, 28-33 weeks and 34-36 weeks gestations, respectively) and bone health conditions (RR: 1.38, 95% CI: 1.27-1.49; RR: 1.04, 95% CI 1.00-1.08; RR: 1.05 95% CI 1.03-1.07 for 22-27 weeks, 28-33 weeks and 34-36 weeks gestations, respectively). There was no difference in rates of conditions related to glucose metabolism such as diabetes mellitus or hypoglycemia. Conclusion Children born preterm have increased rates of endocrine conditions by age 5. Disorders of thyroid, growth and development are increased in infants born preterm. Children born preterm have an increase rate of bone-related disorders, including those born late-preterm. These results provide useful prognostic information for follow-up care for preterm children and for healthcare resource planning. Furthermore, these results highlight areas of future research in endocrine health among preterm infants.

Unexplored topics in intrahepatic cholestasis of pregnancy: A review and bibliometric analysis.

To conduct a comprehensive bibliometric analysis of research published on intrahepatic cholestasis of pregnancy (ICP) and explore the related frontiers and critical issues concerning it, we searched the Web of Science Core Collection for ICP-related publications from the beginning of 2001 until August of 2023. CiteSpace and VOSviewer were utilized to evaluate the contribution and co-occurrence relationships of various countries and regions, institutes and so on to identify new frontiers and currently exciting topics. Our bibliometric analysis scrutinized 933 articles from 59 countries/regions. China has generated the largest number of publications (31.6% of the total), whereas Germany ranked first when it came to citations per publication. The Imperial College London ranked first with respect to publication output on ICP and betweenness centrality. The Journal of Maternal-Fetal & Neonatal Medicine was the journal with the highest plurality of papers. Authors such as Williamson, Beuers, Ulrich, and Shao were the most influential. Pregnancy, ursodeoxycholic acid, and ICP were principally noted in publications. Cluster analysis of the references that correlated with the 933 publications showed that they clustered into mortality, ABCB11, BSEP, MRP2, bile acid, and intrahepatic cholestasis. ICP is associated with adverse clinical outcomes for both the mother and fetus. This study provides a critical analysis of the current status and future research trends regarding ICP. It can serve as a useful reference, allowing researchers to conduct in-depth investigations into this promising field.

Management of neonates exposed prenatally to opioids: Impact of a developmental care program implementation

BackgroundTraditional approaches to management of neonates prenatally exposed to opioids are based on the use of pharmacotherapy (PT), adjusted to evolution of infant symptoms. Newer approaches focused on non-pharmacological care (NPC) are emerging, but there is little evidence on the active policies to implement to ensure their widespread practice. The primary objective of the study was to assess whether the implementation of a developmental care program in our neonatal medicine department had an impact on the management of these infants during hospitalization, notably exposure to NPC. MethodObservational study in a tertiary perinatal center. Data collected during hospitalization for infants with in utero opioid exposure included admission in the parents-infant unit (PIU) of the maternity ward, exposure to NPC and PT, occurrence of neonatal opioid withdrawal syndrome (NOWS), length of hospital stay (LOS) and feeding type at discharge. The impact of the intervention was measured by comparing three 6-year periods, the first preceding the implementation of a formalized developmental care program (2003–2008); the second following implementation of the program (2009–2014); the third after consolidation of the program (2015–2020). Results258 infants prenatally exposed to opioid were recorded. From the first to the third period, admission rate in the PIU was comparable (68 % to 73 %, p = 0. 95). Exposure to NPC (37 % to 84 %, p < 0.001) increased, whereas exposure to PT (40 % to 15 %, p = 0.002) and LOS (13 [9–18] days to 8 [6–11] days, p = 0.003) decreased. NOWS occurred in 141 (55 %) infants (63 % to 47 %, p = 0.10). In these infants, decrease in PT was also observed (64 % to 34 %, p = 0.02). After adjustment for perinatal confounders, hospitalization in the PIU (OR 3.23 [1.36; 7.66]; p = 0.008), and the 2015–2020 period (OR 5.11 [2.06; 12.64]; p = 0.004) were associated with absence of PT. ConclusionsAn active policy, supporting the training and warranting the practice of NPC, is essential to reduce medication usage and length of hospitalization in infants exposed in utero to opioids.

Positioning comfort measures in antenatal counselling for periviable infants.

Caring for the extremely premature infant born in the grey zone of viability is the most difficult area of neonatal medicine. Little research has been done on antenatal communication between neonatologists and parents anticipating the birth of a periviable infant. This article analyses 25 antenatal consultations between neonatologists and parents in one Midwestern hospital in the United States of America. It explores how neonatologists position comfort care as one of two predominant care trajectories for extremely premature infants born into the grey zone of viability. We found comfort care featured minimally in and was often marginalised by neonatologists' language. The two dominant discourses contributing to this were acute medicine's life-saving capacity and a limited temporal window marked by gestational age where comfort measures were deemed appropriate. Antenatal consultations framed by shared decision-making could be approached as a form of care characterised by a relational openness and responsiveness to parents' views on care. This asks neonatologists to enter antenatal consultations for periviability without knowing ahead of time which care trajectory will necessarily call one's attention or the particular response one should take, thus highlighting the skills of reflexivity in addition to an attentiveness and openness towards those receiving care.

Monitoring and evaluation of hypotension in the extremely preterm.

With the development of neonatal medicine, more and more extremely preterm infants have been treated. How to deal with hypotension is a big challenge for neonatologist in the process of diagnosis and treatment. The lack of uniformity in the definition of hypotension, challenges in measuring blood pressure accurately, and insufficient consistency between digital hypotension and hypoperfusion are the primary causes. How to check for hypotension and monitor blood pressure is thoroughly explained in the article. To give neonatologists a resource for the clinical management of hypotension in extremely preterm.

The hype of artificial intelligence in neonatology: How close are we to real AI?

Background. Artificial intelligence (AI) use in medicine has rapidly evolved, offering significant advancements in patient monitoring and diagnosis. However, the application of AI in neonatology presents unique challenges compared to adult medicine. While adult patients can often be monitored and treated autonomously through AI-powered tools like telemedicine, newborns, particularly preterm infants, are entirely dependent on continuous human care. In neonatology, human interaction—especially the tactile and empathetic care provided by nurses and doctors—remains critical, and AI systems are not equipped to replace this essential element of care. Concerns that AI might displace medical personnel in neonatal settings are unfounded, as human intervention remains irreplaceable. Discussion. Current AI technologies, often referred to as AI, are more accurately described as advanced machine learning algorithms and sophisticated software rather than true general artificial intelligence (AGI). These systems can efficiently perform well-defined tasks, such as monitoring vital signs and adjusting mechanical ventilators. However, they lack the broader understanding and adaptability necessary for independent clinical decision-making. They cannot interpret complex clinical contexts or address multifactorial medical decisions, which are still the domain of human expertise. Despite the limitations, AI holds significant potential in neonatology. It can assist in optimizing treatment protocols, such as adjusting mechanical ventilation in real-time or personalizing antibiotic treatments based on microbiological data. Furthermore, clinical decision support systems (CDSS) powered by AI can provide clinicians with evidence-based recommendations, thereby enhancing decision-making processes and improving patient outcomes. Conclusion. While promising, AI in neonatology remains a supplementary tool rather than a replacement for human judgment. Its role will likely expand, but direct human care and expertise will continue to be essential in neonatal medicine, mitigating concerns about job displacement among healthcare professionals.

Red Blood Cell Transfusion for Incidence of Retinopathy of Prematurity: Prospective Multicenter Cohort Study.

Retinopathy of prematurity (ROP) is a leading cause of visual impairment and blindness in preterm infants. This study sought to investigate the association between red blood cell (RBC) transfusion and ROP in very preterm infants (VPIs) to inform clinical strategies for ROP prevention and treatment. We designed a prospective multicenter cohort study that included VPIs and follow-up data from January 2017 to December 2022 at 3 neonatal clinical medicine centers. They were categorized into a transfusion group (infants who received an RBC transfusion within 4 wk) and a nontransfusion group. The relationship between RBC transfusion and ROP incidence was assessed using binary logistic regression, with subgroup analyses based on gestational age, birth weight, sex, and sepsis status. Inverse probability of treatment weighting and propensity score matching were applied to account for all potential confounding factors that could affect ROP development, followed by sensitivity analysis. The study included 832 VPIs, including 327 in the nontransfusion group and 505 in the transfusion group. The transfusion group had a lower average birth weight and gestational age and a greater incidence of ROP, ≥stage 2 ROP, and severe ROP. Logistic regression analysis revealed that the transfusion group had a significantly greater risk of ROP (adjusted odds ratio [aOR] 1.70, 95% CI 1.14-2.53, P=.009) and ≥stage 2 ROP (aOR 1.68, 95% CI 1.02-2.78, P=.04) but not severe ROP (aOR 1.75, 95% CI 0.61-5.02, P=.30). The trend analysis also revealed an increased risk of ROP with an increasing number of transfusions and a larger volume of blood transfused (P for trend<.001). Subgroup analyses confirmed a consistent trend, with the transfusion group at a higher risk for ROP across all subgroups. Inverse probability of treatment weighting and propensity score matching analyses supported the initial findings. For VPIs, RBC transfusion significantly increases the risk of ROP, and the risk increases with an increasing number of transfusions and volume of blood transfused.

Change in the prevalence of extra-uterine growth restriction in very low birthweight infants, following the introduction of a written nutrition protocol, in a tertiary neonatal unit

Background: Advances in neonatal medicine, resulting in improved survival, have brought the concept of extra-uterine growth restriction (EUGR), defined as postnatal growth failure secondary to protein and energy deficits, to the forefront as an important cause of morbidity, particularly in very low birthweight (VLBW) neonates. Objectives: This study’s main objective was to determine the prevalence of EUGR in Steve Biko Academic Hospital in VLBW infants. Methods: This was a pre- (epoch 1) and post- (epoch 2) intervention study. The intervention was the introduction of a written nutritional protocol in the neonatal unit in mid-November 2017. Three definitions were used to identify EUGR, namely: (1) discharge weight < 10th percentile, (2) a change by −1.28 z-score in weight at discharge, and (3) the discharge weight percentile below the nadir percentile. Results: The prevalence of EUGR in epoch 1 was 85.7%, 63.5%, and 88.0% using the above definitions, respectively. The prevalence of EUGR in epoch 2 was 73.9%, 65.8%, and 89.4% using the above definitions, respectively. EUGR using the three definitions combined was present in 95.2% and 92.8% of infants in epochs 1 and 2, respectively. None of the differences in EUGR prevalence between the two epochs were significant. Conclusion: The prevalence of EUGR was not significantly different between the two epochs, although it had been proposed that the introduction of a written nutritional protocol would have decreased the prevalence of EUGR in epoch 2. One of the reasons proposed for this finding was poor adherence to the nutritional protocol during epoch 2.

LOX-mediated ECM mechanical stress induces Piezo1 activation in hypoxic-ischemic brain damage and identification of novel inhibitor of LOX

Hypoxic-ischemic encephalopathy (HIE) poses a significant challenge in neonatal medicine, often resulting in profound and lasting neurological deficits. Current therapeutic strategies for hypoxia-ischemia brain damage (HIBD) remain limited. Ferroptosis has been reported to play a crucial role in HIE and serves as a potential therapeutic target. However, the mechanisms underlying ferroptosis in HIBD remain largely unclear. In this study, we found that elevated lysyl oxidase (LOX) expression correlates closely with the severity of HIE, suggesting LOX as a potential biomarker for HIE. LOX expression levels and enzymatic activity were significantly increased in HI-induced neuronal models both in vitro and in vivo. Notably, we discovered that HI-induced brain tissue injury results in increased stiffness and observed a selective upregulation of the mechanosensitive ion channel Piezo1 in both brain tissue of HIBD and primary cortex neurons. Mechanistically, LOX increases its catalytic substrates, the Collagen I/III components, promoting extracellular matrix (ECM) remodeling and possibly mediating ECM cross-linking, which leads to increased stiffness at the site of injury and subsequent activation of the Piezo1 channel. Piezo1 senses these stiffness stimuli and then induces neuronal ferroptosis in a GPX4-dependent manner. Pharmacological inhibition of LOX or Piezo1 ameliorated brain neuronal ferroptosis and improved learning and memory impairments. Furthermore, we identified traumatic acid (TA) as a novel LOX inhibitor that effectively suppresses LOX enzymatic activity, mitigating neuronal ferroptosis and promoting synaptic plasticity. In conclusion, our findings elucidate a critical role for LOX-mediated ECM mechanical stress-induced Piezo1 activation in regulating ferroptotic cell death in HIBD. This mechanistic insight provides a basis for developing targeted therapies aimed at ameliorating neurological outcomes in neonates affected by HIBD.

The Potential of Ambroxol as a Panacea for Neonatal Diseases: A Scoping Review.

Ambroxol, a commonly used mucolytic agent, has been extensively studied for its clinical effectiveness in managing respiratory conditions in pediatric and adult patients. The existing body of research on ambroxol demonstrates its safety and efficacy. However, its potential role in preventing and treating neonatal diseases still needs to be explored. This scoping review aims to shed light on the unexplored potential of ambroxol, particularly its applications in perinatal and neonatal care. We aim to offer valuable insights for healthcare professionals, researchers, and academics, thus presenting a positive perspective. Key scientific databases such as Google Scholar, PubMed, Cochrane Library, and Europe PMC were meticulously searched for relevant literature on ambroxol in perinatal and neonatal medicine. Gray literature was also surveyed, and the search encompassed all study designs and languages up to June 2024. Furthermore, citations and reference lists of relevant articles were scrutinized to identify additional pertinent literature. Ambroxol has demonstrated promising effects in preventing and managing respiratory distress syndrome (RDS). It can enter the placental circulation and rapidly build up in human lung tissue to a much greater extent than in plasma. It promotes fetal lung maturation, surfactant production, and alveolar expansion. Numerous studies have demonstrated the efficacy of antenatal and postnatal ambroxol in the prevention and treatment of RDS. Ambroxol has the potential to be administered intravenously or through nebulization, offering the hopeful possibility of reducing the high failure rate typically associated with non-invasive ventilation in extremely preterm infants, instilling a sense of hope and optimism about the potential of ambroxol. It also shows potential in treating bronchopulmonary dysplasia, meconium aspiration syndrome, and neonatal infections. Ambroxol has been observed to assist in the closure of patent ductus arteriosus in preterm infants by inhibiting vasodilator agents such as nitric oxide and exerting vasoconstrictive properties. However, these biological actions may raise concerns regarding the potential induction of pulmonary hypertension and an increased risk of necrotizing enterocolitis. The present scoping review also examines the clinical evidence and the potential of ambroxol in reducing the incidence of intraventricular hemorrhage in preterm infants. Ambroxol may have potential analgesic properties in managing neonatal pain, and as it can penetrate the blood-brain barrier, it suggests potential neuroprotective properties. These properties may encompass the modulation of microglial activation and the antagonistic impact on glutamate receptors. Ambroxol's attributes could contribute to a decreased susceptibility to neurological complications and have demonstrated anticonvulsant effects in preclinical studies. While low-to-moderate-quality evidence indicates potential applications of ambroxol in neonatal care, further research is needed to determine the drug's optimal dosing, timing, and safety profiles in this patient population. We need to investigate ambroxol's potential synergistic effects with antenatal steroids. Exploration is required to assess ambroxol's potential in reducing the high failure rate associated with non-invasive respiratory support for RDS. Lastly, comprehensive studies on the long-term neurodevelopmental outcomes of neonates exposed to ambroxol are essential.

Improving the future of clinical trials and translation of mesenchymal stromal cell therapies for neonatal disorders.

Despite recent advances in neonatal intensive care medicine, neonatal disorders such as (bronchopulmonary dysplasia [BPD], intraventricular hemorrhage [IVH], and hypoxic ischemic encephalopathy [HIE]) remain major causes of death and morbidity in survivors, with few effective treatments being available. Recent preclinical studies have demonstrated the pleiotropic host injury-responsive paracrine protective effects of cell therapy especially with mesenchymal stromal cells (MSCs) against BPD, IVH, and HIE. These findings suggest that MSCs therapy might emerge as a novel therapeutic modality for these currently devastating neonatal disorders with complex multifactorial etiologies. Although early-phase clinical trials suggest their safety and feasibility, their clinical therapeutic benefits have not yet been proven. Therefore, based on currently available preclinical research and clinical trial data, we focus on critical issues that need to be addressed for future successful clinical trials and eventual clinical translation such as selecting the right patient and optimal cell type, route, dose, and timing of MSCs therapy for neonatal disorders such as BPD, HIE, and IVH.

Bioinformatics in Neonatal/Pediatric Medicine-A Literature Review.

Bioinformatics is a scientific field that uses computer technology to gather, store, analyze, and share biological data and information. DNA sequences of genes or entire genomes, protein amino acid sequences, nucleic acid, and protein-nucleic acid complex structures are examples of traditional bioinformatics data. Moreover, proteomics, the distribution of proteins in cells, interactomics, the patterns of interactions between proteins and nucleic acids, and metabolomics, the types and patterns of small-molecule transformations by the biochemical pathways in cells, are further data streams. Currently, the objectives of bioinformatics are integrative, focusing on how various data combinations might be utilized to comprehend organisms and diseases. Bioinformatic techniques have become popular as novel instruments for examining the fundamental mechanisms behind neonatal diseases. In the first few weeks of newborn life, these methods can be utilized in conjunction with clinical data to identify the most vulnerable neonates and to gain a better understanding of certain mortalities, including respiratory distress, bronchopulmonary dysplasia, sepsis, or inborn errors of metabolism. In the current study, we performed a literature review to summarize the current application of bioinformatics in neonatal medicine. Our aim was to provide evidence that could supply novel insights into the underlying mechanism of neonatal pathophysiology and could be used as an early diagnostic tool in neonatal care.

Global research status of intrahepatic cholestasis of pregnancy: A bibliometric analysis of hotspots, bursts, and trends

BackgroundResearch on intrahepatic cholestasis of pregnancy (ICP) has recently gained attention. However, no bibliometric analysis was performed in the ICP research field. Therefore, the present study aimed to use bibliometric analysis to analyze the current research hotspots and identify global research status in ICP to reference for future research directions. MethodsWe comprehensively searched the Web of Science Core Collection (WoSCC) database from its inception to December 31, 2023. Articles and reviews related to ICP were downloaded as plain text file records. We used the VOSviewer and Citespace to perform the bibliometric analysis and visualization. The main bibliometric features were tabulated and calculated. ResultsA total of 1092 documents, including 921 original articles and 171 reviews, were identified in WoSCC. These publications were published in 395 journals by 4751 authors from 1250 institutions and 61 countries/regions. The global publication numbers exhibited a gradual upward trend. China, the United States, and the United Kingdom were top contributors to scientific research on ICP. King's College London, London Imperial Coll Sci Technol & Med, and Sichuan University were the most productive institutions. Catherine Williamson had published the most papers and received the most total citations. The most productive journal was Journal of Maternal-Fetal & Neonatal Medicine. The most cited paper was Beuers et al. in the Journal of Hepatology (2009). Citation burst terms showed that “risk factors” and “perinatal outcomes” were hotspots. “Inflammation”, “risk factors”, “perinatal outcomes”, and “bile acid” have gained attention in more recent research. ConclusionThe present study comprehensively summarizes the global research status and research trends in ICP. Our study identifies hotspots, collaborative networks, and trends that will provide new insights and guidance for further research in the field.
