Background/Objective: Early diagnosis of neonatal sepsis remains a challenge due to the nonspecific nature of clinical symptoms and the delayed dynamics of conventional inflammatory markers. The traditional diagnostic approach is based on static cut-off points, which often do not consider the nonlinear nature of the inflammatory response. The aim of this study was to identify dynamic variables associated with sepsis progression, constituting the foundation for future artificial intelligence (AI) models. Methods: A retrospective analysis was performed using anonymised clinical and laboratory data from a cohort of newborns (n = 122) with suspected sepsis, along with maternal clinical data. Using feature engineering, descriptive statistics parameters were generated for selected parameters, including rates of change in the 24 h and 48 h time windows. This was combined with the verification of clinical and perinatal parameters that affect the assessment of clinical status and diagnosis of sepsis. The correlation analysis was performed using Spearman’s rank correlation coefficient (p < 0.05). Results: Dynamic parameters showed significant associations with sepsis progression than static measurements. The highest correlation was recorded for the rate of CRP growth (CRP_abs_change_rate_max, r = 0.613, p < 0.001), compared with the maximum values (CRP_value_max, r = 0.591, p < 0.001). High correlations were also observed for leukocyte parameters, especially neutrophils (NEUT_%_pct_change_rate_max, r = 0.547, p < 0.001) and basophils (BASO_%_value_max, r = 0.606, p < 0.001), with the strongest correlations observed within the first 24 h (r > 0.70). Conclusions: Neonatal sepsis progression may be more comprehensively characterised by temporal changes in laboratory parameters, not by their absolute values. Rates of change in inflammatory markers may provide clinically relevant complementary information on the course of the disease, reflecting the complex and nonlinear nature of the inflammatory response. The results indicate that the analysis of the trajectory of changes in parameters provides a promising basis for the future development and validation of predictive models based on artificial intelligence for earlier and more accurate diagnosis of neonatal sepsis.

Due to the extreme immaturity of many internal organs, including lungs, infants at the limit of viability are more predisposed to a pneumothorax (PTX). In some cases, PTX becomes persistent. Previously, only a few attempts of PTX treatment with fibrin glue were reported. However, its impact on further lung development is unknown. We present a case of an extremely preterm infant with persistent PTX who was successfully treated with fibrin glue. In addition, we present a two-and-a-half-year corrected age follow-up focusing on respiratory problems, motor development and sensory organs. Furthermore, we touch upon the related ethical issues. Fibrin glue should be used to treat persistent PTX even in an extremely preterm infant. No adverse effects were observed. At the two-and-a-half-year corrected age follow-up, despite severe bronchopulmonary dysplasia development, no serious pulmonary problems were observed. However, the child's development is uncertain. This situation raises important ethical issues concerning saving the lives of infants at the limit of viability.

Greater awareness of possible iatrogenic esophageal perforation (EP) is needed. Though rare, EP is a legitimate health risk as it may lead to long-term morbidities. This study presents and discusses iatrogenic EP in a subset of preterm infants. Using radiographic images, we study and describe the consequences of the orogastric/nasogastric tube position (in radiographic images). We analyze the possible influence of histological chorioamnionitis on the development of esophageal perforation. This retrospective study examines the hospital records of 1149 preterm infants, 2009–2016, with very low birth weight (VLBW) and iatrogenic EP, comparing mortalities and morbidities between the two groups of preterm infants who had birth weights (BWs) of less than 750 g and were less than 27 weeks gestation age at birth: one group with iatrogenic esophageal perforation (EP group) and one group without perforation (non-EP group—the control group). Histopathological chorioamnionitis of the placenta showed no statistically significant differences between the groups. The only statistically significant difference was in the air leaks (p = 0.01). Three types of nasogastric tube (NGT) X-ray location were identified, depending on the place of the perforation: (1) high position below the carina mimicking esophageal atresia; (2) low, intra-abdominal; (3) NGT right pleura-directed. We also highlight the particular symptoms that may be indicative of EP due to a displacement of the nasogastric tube.

Pain experienced in the neonatal period has been shown to have serious short- and long-term consequences. It is also known that painkillers have side effects and should not be abused. The basis of proper pain management is assessment of pain, which in newborns is very difficult due to the lack of verbal communication. In these patients, behavioural scales are used to assess pain, but they have numerous shortcomings. For this reason, many newborns treated in the ICU are at risk of pain, so instrumental methods of detecting and assessing the severity of pain are being sought. During three months, seven Polish NICUs conducted research with the use of NIPE and SCA monitors. After this time, the heads of these departments filled in questionnaires regarding their individual opinions on the usefulness of these devices. All respondents found pain monitors useful in the NICU. The NIPE monitor was rated slightly higher, as its usefulness in assessing the effectiveness of analgosedation and in the management of patients in the postoperative period was better rated. The high acceptance of both devices by legal guardians of newborns is noteworthy. It should be stated that in newborns, any way to improve pain monitoring is valuable. In the opinion of Polish experts, pain monitors are useful in NICU. The NIPE monitor was assessed a little higher and was considered useful in the assessment of analgosedation and in postoperative treatment. Pain monitors can provide valuable support for pain assessment in newborns treated in the NICU.

Introduction: Adequate analgosedation is important in infants treated in pediatric/neonatal intensive care units (P/NICUs), because both too deep and insufficient analgosedation is disadvantageous. To assess the severity of pain, several behavioral and behavioral-physiological scales are used, but their usefulness is limited. It is therefore justified to search for additional methods to assess the adequacy of analgosedation in these patients. The aim of the present study is to evaluate the usefulness of Newborn Infant Parasympathetic Evaluation (NIPE) in the assessment of analgosedation quality in infants requiring mechanical ventilation, who are treated in P/NICUs.Material and methods: We performed simultaneously 180 COMFORT-B assessments and heart rate variability measurements using a NIPE monitor in 30 mechanically ventilated infants receiving analgosedation. A generalized linear mixed model with the logit link function was used in order to perform logistic regression analysis to assess the relationship between NIPEi/NIPEm and deep sedation.Results: The multivariable logistic regression model showed that NIPEi and NIPEm values were higher when analgosedation was deep as compared to when it was moderate or insufficient (OR (95% CI): NIPEm – 1.065 (1.007– 1.126), p = 0.03; NIPEi – 1.068 (1.016–1.123), p = 0.01).Conclusions: The NIPE indexes are significantly higher in patients whose assessment on the behavioral scale indicates deep analgosedation as compared to those in whom it indicates moderate or insufficient analgosedation. Allowing continuous monitoring, the NIPE device may be a valuable assisting tool in the assessment of analgosedation quality in mechanically ventilated newborns and infants.

Background. Patients treated in neonatal/pediatric intensive care units (N/PICUs) are frequently exposed to pain. To assess its severity, several behavioral and behavioral-physiological scales are used, but their usefulness is limited. It is therefore justified to search for additional methods to assess the adequacy of analgesia and sedation in these patients. Objectives. To evaluate the usefulness of skin conductance (SC) measurement in the assessment of analgosedation quality in infants requiring mechanical ventilation treated in N/PICUs. Material and methods. Thirty infants aged 6-208 days treated in 6 N/PICUs, mechanically ventilated and receiving analgosedation, were included for the study. Simultaneous COMFORT-B assessment and SC measurement using SCA (skin conductance algesimeter) monitor were performed. Due to technical problems, not all of the SC records could be interpreted, and finally 412 simultaneous assessments on the COMFORT-B scale and SC measurements in 29 patients were analyzed. Results. We found a statistically significant correlation between the COMFORT-B scoring and the SC measurements. Additionally, SC was significantly lower when the behavioral score indicated deep sedation, in comparison to periods when it indicated moderate or insufficient analgosedation. Conclusions. Skin conductance measurements are comparable with the COMFORT-B rating in mechanically ventilated infants receiving analgosedation. The SCA monitor may be of value in the assessment of analgosedation quality, and in particular may identify the situation where sedation is deep. Further research is needed regarding the suitability of this device in clinical practice.

Perinatology is a dynamically developing field of medicine. The progress of technology in recent decades has made it possible to recognize birth defects very early, including those which are lethal or genetically determined. In many clinical situations, it is no longer possible to work alone to reach a definitive diagnosis, plan treatment or predict the clinical course of the affected fetus/newborn. There is a need for teamwork, which ensures the proper, early care starting in the fetal period, not only in the delivery room or NICU. This paper discusses the ethical foundations of creating interdisciplinary teams, taking as an example the Interdisciplinary Team for Fetal Malformation at the Institute of Mother and Child in Warsaw, which has been active for 25 years, and presents how it works in practice. On the basis of the clinical cases that are examined, practical guidelines were formulated for both the work of medical teams and the way parents are informed about the clinical situation of their child and about sharing the care after the birth of the child. A document was also proposed with information on prenatal diagnosis, decisions made by the interdisciplinary team regarding the mother and child, as well as the conclusions resulting from discussions with parents.

The aim of the study was to search for the interrelation between the results of neuroimaging and the neurological, psychological and psychiatric evaluation at the age of 2. Neonates born at ≤28 weeks between 01.06.2013 and 31.12.2015 and hospitalized at NICU were enrolled. We present the results of the first 12 children who have attained 2 years of corrected age and have undergone both neuroimaging, and neurological, psychological and psychiatric assessments. Transfontanel ultrasound was performed according to general standards, MRI between 38 and 42 weeks of corrected age. Neurological examination based on the Denver scale, ASD screening with use of the STAT test and psychological DSR assessment were performed at 2 years of corrected age. Median GA was 26 weeks and median weight 795 g. The ultrasound examination was normal in 9 cases (75%) and MRI in 4 (33%). Abnormalities in the cerebellum were the main additional information found in MRI as compared to US. Neurological examination was normal in 8 infants (67%), in 4 of whom neuroimaging was normal. In 4 (33%) infants the neurological examination was abnormal. Psychomotor development at an average level or above was found in seven (58%) children. In 4 of them neuroimaging was normal, whereas 3 had ventricular dilatation and haemorrhagic infarct. There were no abnormalities within the cerebellum in this group. In the remaining 5 children (42%) psychomotor development was rated as delayed. All of them had cerebellar haemorrhage. An increased risk of ASD was observed in 4 children who developed cerebellar hemorrhage. 1. The use of MRI at a term-equivalent age may contribute to the prognosis of neurodevelopmental outcomes in extremely premature infants, allowing risk stratification and thus enhancing early monitoring of a child’s development and functional status 2. There is a clear tendency towards abnormal psychomotor development and positive screening for ASD to co-occur with abnormal MRI findings in the cerebellum.

Background: Severe bronchopulmonary dysplasia (BPD) remains a major complication of prematurity and can have significant impact on long-term pulmonary sequelae and adverse neurodevelopmental outcomes. Objective: To assess the incidence and evaluate the predictive factors for severe BPD in very preterm infants with respiratory distress syndrome. Methods: Of the 846 premature infants born at ≤32-week gestation who developed respiratory distress syndrome (RDS), 707 infants with known oxygen dependency at 36 weeks gestational age were included in the analysis of BPD incidence. With univariate and multiple logistic regression models we evaluated the risk factors for the development of severe BPD and calculated odds ratios (ORs). Results: The overall incidence of BPD was 45.2%. Severe BPD accounted for 6%, with morbidity pertaining mainly to infants 7 days (OR 7.05, 95%CI 2.63–22.4). The protective factors were early continuous positive airway pressure (CPAP) in the univariate analysis and receiving surfactant 7 days is the most prevalent risk factor for severe BPD. CPAP initiated in the delivery room and early surfactant are key preventive measures.
