Approach to neonatal thrombocytopenia.

A low platelet count (thrombocytopenia) is a common finding especially in neonates who are admitted to the neonatal intensive care unit. Due to the varied causes that can lead to neonatal thrombocytopenia, assessment and management can be challenging. Having an understanding of the causes of neonatal thrombocytopenia and their natural progression would help guide subsequent management. Therefore, we will be exploring the different circumstances where thrombocytopenia occurs and how to interpret and manage the neonate with thrombocytopenia in this interpretations article.

Evaluating neonatal pain via fusing vision transformer and concept-cognitive computing

In clinical nursing, neonatal pain assessment is a challenging task for preventing and controlling the impact of pain on neonatal development. To reduce the adverse effects of repetitive painful treatments during hospitalization on newborns, we propose a novel method (namely pain concept-cognitive computing model, PainC3M) for evaluating facial pain in newborns. In the fusion system, we first improve the attention mechanism of vision transformer by revising the node encoding way, considering the spatial structure, edge and centrality of nodes, and then use its corresponding encoder as a feature extractor to comprehensively extract image features. Second, we introduce a concept-cognitive computing model as a classifier to evaluate the level of pain. Finally, we evaluate our PainC3M on various open pain data sets and a real clinical pain data stream, and the experimental results demonstrate that our PainC3M is very effective for dynamic classification and superior to other comparative models. It also provides a good approach for pain assessment of individuals with aphasia (or dementia).

Impact of a qualitative assessment approach for neonatal abstinence syndrome management: experience of a European reference center

BackgroundThe management of infants at risk of neonatal abstinence syndrome (NAS) remains challenging. In 2000 Maternidade Bissaya Barreto implemented a strategy based on the qualitative assessment of neonates and in 2018 the Eat, Sleep, Console (ESC) approach, a tool based on similar concepts, was created. The aim is to assess the efficacy of a qualitative assessment of infants at risk, compare it with the ESC approach and report temporal trends of NAS in a European hospital.MethodsRetrospective cohort study of all infants of mothers with a history of drug abuse during pregnancy admitted to a tertiary European centre between January 2010 and December 2021. The therapeutical decision was guided by a qualitative assessment of the newborn’s well-being. The ESC approach was retrospectively determined. Pharmacologic treatment was used as a last resort. The clinical outcomes and therapeutic strategies employed were evaluated. Statistical association was evaluated. The incidence rate per 1000 births was calculated and temporal trend differences were identified.ResultsA total of 79 neonates at risk were included, of whom 40 (50.6%) developed NAS. Consolability was the most affected criterion (35.0%), followed by feeding difficulties (12.5%). Sleep was affected less frequently (5.0%). Overall, 37.5% of infants failed to meet at least one of the criteria. All neonates with a positive ESC failed the qualitative assessment (p = 1.000) After optimization of nonpharmacologic measures, drug therapy was still necessary in four cases (10.0% of infants with the syndrome). The incidence rate of NAS decreased from 3.9 per 1000 births in 2010 to 0.0 per 1000 births in 2021 (p = 0.025).ConclusionThe qualitative assessment of the infant based on the ability to feed, sleep and be consoled correctly identified neonates at risk and led to a significant reduction in the use of drug therapy. The incidence rate of NAS decreased during the study period.

A systematic catalog of studies on fetal heart rate pattern and neonatal outcome variables.

To study the methodology and results of studies assessing the relationship between fetal heart rate and specified neonatal outcomes including, heart rate, infection, necrotizing enterocolitis, intraventricular hemorrhage, hypoxic-ischemic encephalopathy, and seizure. Embase, Medline ALL, Web of Science Core Collection, Cochrane Central Register of Controlled Trials, and CINAHL were searched from inception to October 5, 2023. Forty-two studies were included, encompassing 57,232 cases that underwent fetal monitoring and were evaluated for neonatal outcome. Heterogeneity was observed in the timing and duration of fetal heart rate assessment, classification guidelines used, number of assessors, and definition and timing of neonatal outcome assessment. Nonreassuring fetal heart rate was linked to lower neonatal heart rate variability. A significant increase in abnormal fetal heart rate patterns were reported in neonates with hypoxic-ischemic encephalopathy, but the predictive ability was found to be limited. Conflicting results were reported regarding sepsis, seizure and intraventricular hemorrhage. No association was found between necrotizing enterocolitis rate and fetal heart rate. There is great heterogeneity in the methodology used in studies evaluating the association between fetal heart rate and aforementioned neonatal outcomes. Hypoxic-ischemic encephalopathy was associated with increased abnormal fetal heart rate patterns, although the predictive ability was low. Further research on developing and evaluating an automated early warning system that integrates computerized cardiotocography with a perinatal health parameter database to provide objective alerts for patients at-risk is recommended.

REIV-TOXO Project: Results from a Spanish cohort of congenital toxoplasmosis (2015-2022). The beneficial effects of prenatal treatment on clinical outcomes of infected newborns.

Some regions of Spain are withdrawing their pregnancy screening program for congenital toxoplasmosis (CT). The Spanish Research Network of Congenital Toxoplasmosis (REIV-TOXO) was created to describe the current status of CT in Spain. The aims of this study were to describe the epidemiological and clinical characteristics of CT and to evaluate the effect of prenatal treatment on clinical outcomes to inform decision-making policies. Ambispective observational study including CT cases recorded in the REIV-TOXO database that includes 122 hospitals (2015-2022). Inclusion criteria were one or more of the following: positive PCR in maternal amniotic fluid; positive Toxoplasma gondii-specific IgM or IgA antibodies at birth; positive PCR in the placenta, newborn blood, urine or CSF; increase of specific IgG levels during infant follow-up; or specific IgG persistence beyond age 12 months. Fifty-six newborns (54 pregnancies) were included. Prenatal screening allowed 92.8% of cases to be identified. The time of maternal infection was well documented in 90.7% of cases, with 61.1% occurring in the third trimester. A total of 66.6% (36/54) pregnant women received antiparasitic treatment: 24/36 spiramycin, 8/36 pyrimethamine, sulfadiazine, and folinic acid, and 4/36 both treatments sequentially. Most cases were asymptomatic at birth (62.5%, 35/56), and 84% (47/56) newborns completed one year of treatment. Median follow-up was 24 months (IQR = 3-72): 14.2% children exhibited new complications, mainly ocular. Newborns born to mothers treated prenatally had four-fold lower risk of CT clinical features at birth (p = 0.03) and six-fold lower risk of further complications during follow-up (p = 0.04) with no treatment-related differences during pregnancy. While diagnosis based only on neonatal assessment misses a significant number of CT cases, prenatal screening allows treatment to be started during pregnancy, with better clinical outcomes at birth and during follow-up. REIV-TOXO provides valuable information about CT in Spain, highlighting the need for universal maternal screening.

The role of multisensory intervention combined with aEEG in the maturation and evaluation of brain and neural development in premature infants of different gestational ages

Objective: To explore the combined effects of multisensory intervention and amplitude integrated electroencephalogram monitoring on the maturation and evaluation of brain and neural development in premature infants of different gestational ages.Methods: The controlled trial was carried out in 62 premature infants from January to February of 2023 in Genertec AMHT – Baogang Hospital. The premature infants were divided into two groups according to the gestational age: 32-33+6W (Group A) and 34-33+6W (Group B). By use of random number table method, each group was subdivided into the control group and the experimental group. The control group was monitored with aEEG within 1 day and the following 7 days after birth. The experimental group was monitored with aEEG within 1 day and the following 7 days after multisensory intervention (MS) to observe the change of aEEG parameters, in order to explore the effect of MS intervention on brain development maturity. The Neonatal Behavioral Neurological Assessment (NBNA) score was performed at 40 weeks of corrected gestational age in both groups.Results: The amplitude voltage, the total aEEG score and the sleep-wake cycle score in the experimental group were higher than those in the control group (p < .05). The total NBNA score in the experimental group was higher than that in the control group.Conclusion: The multi-sensory intervention is a simple and feasible method of development support nursing, it can improve the total NBNA score of premature infants, which can promote the brain development in premature infants and improve their neurodevelopmental behavior.

Understanding stakeholder perspectives on Apgar score, cyanosis and identifying jaundice in ethnic minority neonates.

To explore neonatal assessments that include an element of evaluating skin colour in neonates of black, Asian and minority ethnicities, focusing on the Apgar score, presence of cyanosis and presence of jaundice. We employed focused ethnography involving diverse healthcare professionals (HCPs) and parents or caregivers with Black, Asian, or ethnic minority children born in the last five years. Zoom interviews were performed following a semi-structured interview guide. Ethnographic data analysis was conducted using NVivo software. There was a lack of consistency in how HCPs applied the Apgar scores, which also varied from textbook guidelines. The use of pink as a skin colour descriptor for ethnic minority neonates created a divide among both parents and HCPs. HCPs relied more heavily on other elements of the Apgar score or infant breathing and crying at birth to gauge infant wellness. When identifying cyanosis, HCPs depend on specific body locations for accurate assessment of oxygenation, but the limitations of visual assessment are acknowledged. For jaundice, most HCPs recognised the difficulty in identifying the colour yellow in infants with darker skin tones. HCPs focussed on yellowing of the sclera and gums and other well-being assessments to detect jaundice. Some interviewed parents noticed jaundice in their infants before HCPs but felt they were not listened to when raising concerns. HCPs acknowledged the need for additional training to effectively assess the health of ethnic minority infants. This study highlights disparities in neonatal health assessment from the perspectives of healthcare professionals and parents from diverse backgrounds. Varied practices in determining the Apgar score and recognising cyanosis and jaundice signal the need for standardised protocols, appropriate educational materials, and targeted training. Addressing these challenges is vital for equitable care, emphasising comprehensive training and bias mitigation efforts in maternal and neonatal healthcare.

Developing and Validating a Multimodal Dataset for Neonatal Pain Assessment to Improve AI Algorithms With Clinical Data.

Using Artificial Intelligence (AI) for neonatal pain assessment has great potential, but its effectiveness depends on accurate data labeling. Therefore, precise and reliable neonatal pain datasets are essential for managing neonatal pain. To develop and validate a comprehensive multimodal dataset with accurately labeled clinical data, enhancing AI algorithms for neonatal pain assessment. An assessment team randomly selected healthy neonates for assessment using the Neonatal Pain, Agitation, and Sedation Scale. During painful procedures, 2 cameras recorded neonates' pain reactions on site. After 2weeks, assessors labeled the processed pain data on the EasyDL platform in a single-anonymized setting. The pain scores from the 4 single-modal data types were compared to the total pain scores derived from multimodal data. The On-Site Neonatal Pain Assessment completed using paper quality scales is referred to as OS-NPA, while the modality-data neonatal pain labeling performed using labeling software is MD-NPL. The intraclass correlation coefficient among the 4 single-modal groups ranged from 0.938 to 0.969. The overall pain intraclass correlation coefficient score was 0.99, with a Kappa statistic for pain grade agreement of 0.899. The goodness-of-fit for the linear regression models comparing the OS-NPA and MD-NPL for each assessor was greater than 0.96. MD-NPL represents a productive alternative to OS-NPA for neonatal pain assessment, and the validity of the data labels within the Multimodality Dataset for Neonatal Acute Pain has been validating. These findings offer reliable validation for algorithms designed to assess neonatal pain.

Oral Feeding Readiness Assessment Tools for Preterm Infants

Due to their underdeveloped physiological maturity, preterm infants often face challenges related to sucking, breathing, and swallowing coordination during initial feeding. This lack of coordination may lead to episodes of apnea and choking, resulting in unstable vital signs. Preterm infants with this issue must gradually learn oral feeding skills appropriate to their developmental stage. Registered nurses play a critical role in assessing the right time to transition from tube to oral feeding and in providing a safe and positive oral feeding experience. In this article, three validated assessment tools for feeding premature infants are introduced, accompanied by clinical research data demonstrating their use in clinical practice. These three tools include: (1) the Neonatal Oral Motor Assessment Scale, which is applied to evaluate oral motor skills using observations of nonnutritive sucking and the sucking state during the two minutes before feeding; (2) the Premature Oral Feeding Readiness Assessment Scale, which is used to assess readiness for oral feeding in preterm infants; and (3) the Early Feeding Skills assessment, which is used to evaluate the oral feeding skills of preterm infants. These tools aid nurses in helping preterm infants achieve independent oral feeding, facilitating earlier discharge and return to home. The clinical implications and effectiveness of these tools are also discussed to provide to nurses the means and confidence necessary to apply them appropriately in clinical settings.

Comparative analysis of artificial intelligence and expert assessments in detecting neonatal procedural pain

Assessing pain in newborns in the NICU is crucial due to their frequent exposure to painful stimuli, yet it's challenging due to the subjective nature of current methods. This study aimed to evaluate the effectiveness of an AI system designed for automatic facial recognition by comparing its performance with the expert opinion of health care provider. This is a secondary analysis from an eye-tracking study, assessing neonatal pain evaluations by healthcare professionals. The performance of AI software, FaceReader 9, was compared to experts' evaluations using a visual-analog scale, focusing on identifying specific facial action units associated with different pain levels. The study found significant differences in AI-generated metrics—arousal and valence—across three stimulus types: non-noxious thermal, short-noxious, and prolonged-noxious, with p-values below 0.001. A strong correlation (r = 0.84, p ≤ .001) was observed between AI metrics and expert ratings. Eleven facial action units were identified as relevant to describe neonatal pain. The findings highlight the AI system's potential in accurately detecting and analyzing newborn facial expressions in response to varying pain intensities, demonstrating a significant correlation with healthcare professionals' assessments. This suggests that AI technology could enhance objective pain assessment in neonates.

Changes in short-chain fatty acids affect brain development in mice with early life antibiotic-induced dysbacteriosis.

Early enteral nutrition and the gut microbiota profoundly influence neonatal brain development, with short-chain fatty acids (SCFAs) from the microbiota playing a pivotal role. Understanding the relationship between dysbiosis, SCFAs, and brain development is crucial. In this study, we investigated the impact of antibiotics on the concentration of SCFAs in neonatal feces. Additionally, we developed a model of gut dysbiosis in neonatal mice to examine the potential relationship between this imbalance, SCFAs production, and brain function development. We measured the SCFAs content in the feces of two groups of neonates, categorized based on whether antibiotics were used, and conducted the Neonatal Behavioral Neurological Assessment (NBNA) test on all neonates. Then we evaluated fecal SCFAs levels in neonates and neonatal mice post-antibiotic treatment using liquid chromatography-mass spectrometry (LC-MS) analysis. Morris water maze (MWM) tests assessed behavioral performance, and western blot analysis examined brain tissue-related proteins-neuron-specific enolase (NSE), ionized calcium binding adaptor molecule-1 (IBA1), and myelin basic proteins (MBP). The use of antibiotics did not affect the NBNA scores of the two groups of neonates, but it did reduce the SCFAs content in their feces. Antibiotic administration induced gut dysbiosis in mice, resulting in decreased IBA1 and MBP expression. Interventions to restore gut microbiota ameliorated these effects. Mice with dysbiosis displayed cognitive deficits in the MWM test. SCFAs levels decreased during dysbiosis, and increased upon microbiota recovery. Neonatal dysbiosis affects the microbiota-gut-brain axis, impairing cognitive function and nervous system development. Reduced SCFAs may contribute significantly to these alterations.

Long-term outcomes of congenital cytomegalovirus infection in children early identified by extended hearing-targeted screening

ObjectivesCongenital Cytomegalovirus (cCMV) has been associated with hearing, vision, and neurodevelopmental long-term sequelae. Despite the social burden associated with the disease, a universally accepted consensus on screening, diagnostic, therapeutic and follow-up approaches has not been reached. The present observational retrospective study aims at describing long-term sequelae and radiological abnormalities associated with cCMV in children early identified by extended hearing-targeted screening and evaluated by audiological follow-up in a single III Level Audiological Referral Center for at least 2 years. MethodsAudiological neonatal and follow-up data were available for all subjects. Data collection included clinical neonatal and virological assessment at birth. Ophthalmological, neurodevelopmental and neuroradiological follow-up abnormalities compatible with cCMV sequelae were collected by clinical reports. Spearman's rank correlation coefficient (rho-ρ) was used to evaluate possible correlations among the considered parameters. Results61 newborns were identified by extended hearing-targeted cCMV screening and diagnosed mostly (83.6 %) by PCR viral DNA extraction in urine collected within the 15° day of life. Seventeen babies were born preterm, with a mean gestational age of 33.5 weeks. Sixteen patients (26.2 %) were admitted to an Intensive or sub-Intensive Neonatal Care Unit. At birth, 35 newborns were symptomatic (57.3 %), and 19 of them received antiviral treatment by valganciclovir or ganciclovir. Overall, 20 children (32.7 %) were diagnosed with sensorineural hearing loss (SNHL), among them 17 (85 %) were refer at the newborn hearing screening while 3 (15 %) were Pass. 5/20 children (25 %) presented isolated SNHL, while in 15/20 (75 %) children SNHL was associated to other long-term sequelae. In 5 patients (25 %) a progression of the hearing threshold was observed, with a mean age of progression of 26 months of age. Risk factors for progression were a worse final hearing threshold (Spearman's ρ = 0.434; p = 0.0001) and a worse hearing threshold at birth (Spearman's ρ = 0.298; p = 0.020). Thirteen children were fitted with hearing aids, 8 of whom subsequently underwent cochlear implantation. Concerning long term impairments, 10/61 children (17 %) presented a variety of ophthalmological sequelae, while 16/40 cCMV patients (40 %) were diagnosed with neurodevelopmental abnormalities. Language delays were significantly associated with a worse hearing threshold (ρ = 0.582; p = 0.0001) and with other neurocognitive abnormalities (ρ = 0.677, p = 0.0001). 30 children underwent radiological brain evaluation by Magnetic Resonance Imaging, and 63.3 % of them presented abnormalities compatible with cCMV. Mean viral load at birth did not show significant associations with long-term sequelae. ConclusionsThe study highlights the diverse and significant long-term sequelae of cCMV infection detected through early screening. With a significant proportion of cCMV children developing sensorineural hearing loss, ophthalmological and neurodevelopmental issues, the results emphasize the importance of continuous, multidisciplinary follow-up. Early identification and tailored interventions are crucial for improving the long-term health and quality of life of children affected by cCMV.

Correlation of cardiotocography with combined APGAR scores and diagnostic performance of umbilical cord parameters in predicting low combined APGAR scores – A prospective Cohort study

ObjectivesCombined Apgar score includes utilization of interventions such as Continuous positive airway pressure, Oxygen, Mask and Bag ventilation, I ntubation and ventilation, Ne onatal chest compression, Drugs, and newborn assessment. It has been proposed as a substitute for conventional Apgar score which is the gold standard for evaluating newborns right after birth but is impacted by medical interventions and preterm. Combined Apgar scores were examined to check for correlation with CTG tracing and umbilical cord blood parameters which gives an objective assessment of fetal hypoxia, in response to the demand for a more accurate tool for evaluating the neonate and to be used for medico-legal purposes. The study's objectives were to (1) determine the association of combined Apgar scores with suspicious and pathological CTG (2) the association of umbilical cord parameters with low combined Apgar scores and the diagnostic performance of these parameters in predicting low combined Apgar scores. Study designA prospective observational cohort study was conducted in a tertiary care center in East India. 2350 consecutive laboring mothers who had completed 34 weeks of gestation underwent cardiotocography according to institutional protocol and those with suspicious and pathological CTG who delivered within 1 h of abnormal CTG were recruited. Arterial blood was analyzed and the newborn was evaluated immediately after delivery with a combined Apgar scoring system ResultsOf the 2350 women, 50.7 % and 49.3 %, respectively, exhibited suspicious and abnormal CTG tracings. CTG was reported to have low diagnostic accuracy and specificity, with a sensitivity of 66.7 % and 88.9 %, respectively, in detecting combined Apgar at 1 and 5 min. The combined Apgar score at five minutes showed a strong association with acidosis. There was a statistically significant correlation between low combined Apgar and excess lactate and base at one and five minutes. With 100 % sensitivity and 95 % specificity, high lactate levels > 4.1 mM/L were found to predict newborn encephalopathy. ConclusionUmbilical cord blood parameters were found to be correlated with low combined Apgar scores. Combined Apgar scores may be a more useful tool for neonatal assessment and long-term morbidity of newborns. Additional research is required to determine whether it can take the role of conventional Apgar scores in clinical practice.

Validation of Gene Expression Patterns for Oral Feeding Readiness: Transcriptional Analysis of Set of Genes in Neonatal Salivary Samples.

Neonatal health assessment is crucial for detecting and intervening in various disorders. Traditional gene expression analysis methods often require invasive procedures during sample collection, which may not be feasible or ideal for preterm infants. In recent years, saliva has emerged as a promising noninvasive biofluid for assessing gene expression. Another trend that has been growing is the use of "omics" technologies such as transcriptomics in the analysis of gene expression. The costs for carrying out these analyses and the difficulty of analysis make the detection of candidate genes necessary. These genes act as biomarkers for the maturation stages of the oral feeding issue. Salivary samples (n = 225) were prospectively collected from 45 preterm (<34 gestational age) infants from five predefined feeding stages and submitted to RT-qPCR. A better description of the targeted genes and results from RT-qPCR analyses were included. The six genes previously identified as predictive of feeding success were tested. The genes are AMPK, FOXP2, WNT3, NPHP4, NPY2R, and PLXNA1, along with two reference genes: GAPDH and 18S. RT-qPCR amplification enabled the analysis of the gene expression of AMPK, FOXP2, WNT3, NPHP4, NPY2R, and PLXNA1 in neonatal saliva. Expression results were correlated with the feeding status during sample collection. In summary, the genes AMPK, FOXP2, WNT3, NPHP4, NPY2R, and PLXNA1 play critical roles in regulating oral feeding and the development of premature infants. Understanding the influence of these genes can provide valuable insights for improving nutritional care and support the development of these vulnerable babies. Evidence suggests that saliva-based gene expression analysis in newborns holds great promise for early detection and monitoring of disease and understanding developmental processes. More research and standardization of protocols are needed to fully explore the potential of saliva as a noninvasive biomarker in neonatal care.

Prognostic value of serum high-mobility group box 1 in neonates with neonatal encephalopathy.

This study aimed to investigate the diagnostic potential of serum high-mobility group box 1 (HMGB1) in neonatal encephalopathy (NE). A retrospective study was conducted, analyzing 216 neonates diagnosed with NE. The neonates were divided into two groups based on their outcomes at 28 days. Serum HMGB1 levels were compared between the two groups. ROC analysis was used to determine the predictive value of HMGB1. At 28 days, 174 infants had a good prognosis, while 42 had a poor prognosis. Infants with a poor prognosis had higher serum HMGB1 concentrations within 24 h of birth. Multifactorial analysis revealed that extremely preterm birth, extremely low birth weight, an Apgar score of 0-3 at 5 min, premature rupture of membranes by the mother, moderate to severe NE, and serum HMGB1 > 6.14 ng/mL are independent risk factors for poor prognosis. HMGB1 has predictive value for short-term prognosis with an area under the curve of 0.79. Elevated HMGB1 levels in the acute phase of NE are associated with poor short-term neonatal outcomes. The decrease in HMGB1 concentrations over time correlates with a good prognosis; whereas an increase suggests a poor prognosis. Early measurement of serum HMGB1 could aid in the prognostic assessment of neonates with NE. Although serum HMGB1 has emerged as a potential predictor of neonatal outcomes in neonatal encephalopathy, the relationship of HMGB1 levels to neonatal encephalopathy severity remains unclear. The current results demonstrate that infants with a poor prognosis had higher serum HMGB1 concentrations within 24 h of birth. Importantly, elevated serum HMGB1 levels in the acute phase of neonatal encephalopathy are associated with poor short-term neonatal outcomes. Our findings reveal the clinical values of HMGB1 in the prediction of neonatal outcomes in NE patients.

Noninvasive microvascular imaging in newborn rats using high-frequency ultrafast ultrasound

Ultrasound imaging stands as the predominant modality for neonatal health assessment, with recent advancements in ultrafast Doppler (μDoppler) technology offering significant promise in fields such as neonatal brain imaging. Combining μDoppler with high-frequency ultrasound (HF-μDoppler) presents a potential efficient avenue to enhance in vivo microvascular imaging in small animals, notably newborn rats, a crucial preclinical animal model for neonatal disease and development research. It is necessary to verify the imaging performance of HF-μDoppler in preclinical trials. This study investigates the microvascular imaging capabilities of HF-μDoppler using a 30 MHz high-frequency linear array probe in newborn rats. Results demonstrate the clarity of cerebral microvascular imaging in rats aged 1 to 7 postnatal days, extending to whole-body microvascular imaging, encompassing the central nervous system, including the brain and spinal cord. In conclusion, HF-μDoppler technology emerges as a reliable imaging tool, offering a new perspective for preclinical investigations into neonatal diseases and development.

Non-Invasive Electrical Cardiometry versus Echocardiography for Assessment of Patent Ductus Arteriosus Hemodynamic Response to Medical Treatment in Preterm Neonates

Abstract Background Patent ductus arteriosus (PDA) poses a diagnostic and a therapeutic dilemma for neonatologists. Although echocardiography (Echo) has been the gold standard diagnostic tool for PDA, it requires a trained cardiologist or neonatologist to perform and it is usually not available around the clock. Echo provides also a single rather than continuous assessment of the sick neonates, whose hemodynamic status changes quickly. Electrocardiometry (EC) is a new device for continuous hemodynamic monitoring of neonates. Aim of the Work To evaluate the accuracy and precision of EC in comparison to ECHO in assessment of PDA response to treatment in preterm neonates. Patients and Methods This diagnostic accuracy study was conducted in the neonatal intensive care units (NICUs) of Children’s Hospital of Ain Shams University, Cairo, between (1/5/2021 and 31/3/2022). The study was approved by the ethical committee of Ain Shams University. Preterm neonates&amp;lt;35weeks gestational age admitted during the study period were eligible for enrollment. Neonates with hemodynamically non-significant PDA and those with other congenital anomalies were excluded. A baseline echo and electrical cardiometry were done at the time of enrollment and on day 5. Results Forty neonates were enrolled (27 females, 13 males). Closure rate of oral ibuprofen was 100% (39/39) while paracetamol failed to close the PDA in one patient (closure success 0%). Echo and EC didn’t agree upon the tested parameters (stroke volume (SV), cardiac index (CI), ejection fraction (EF), cardiac output (CO) but agreed in measuring heart rate (HR). In patients with inotropes, Echo detected significant changes in CO (p = 0.044) and CI (p = 0.047) but no changes in SV, EF and HR (p = 0.41, 0.506 &amp; 0.105 respectively). In patients who needed mechanical ventilation, Echo detected significant changes in CI (p = 0.008), CO (0.006) and SV (0.042). No changes were detected in any parameter by EC in patients who needed either inotropes or mechanical ventilation (p &amp;gt; 0.05 in all parameters). Conclusion While EC is safe and an easy to apply device, our results show that electrocardiometry is not as accurate as the echocardiography in predicting the hemodynamic changes that might correspond to the closure of PDA in preterm neonates with hemodynamically significant PDA.

Prognostic Value of Pentraxin 3 and Procalcitonin in Late onset Neonatal Sepsis

Abstract Background Sepsis is a major cause of intensive care unit (ICU) admission. Procalcitonin (PCT) could be an important prognostic marker for sepsis. Pentraxin 3 (PTX3) and PCT are detectable in patients with sepsis within a large time window after the onset of sepsis. Objective To assess the prognostic value of the PTX3, PCT in neonatal sepsis in comparison with other sepsis screen. Patients and Methods A prospective study included 40 neonates with sepsis. The study had been conducted in the neonatal intensive care units of Ain Shams University, Children’s Hospital during the period from January 2020 to May 2022. All neonates had been subjected to clinical examination, anthropometric measurements and sepsis scoring by neonatal sequential organ failure assessment (nSOFA). Laboratory investigations were collected from all pediatrics including Complete blood count (CBC), quantitative C- reactive protein (CRP), blood culture, serum pentraxin 3 (PTX3) and serum procalcitonin (PCT). Sepsis markers had been obtained from neonates at the day of being with suspected sepsis before starting the antimicrobial therapy (Day 0). While blood samples for sepsis markers reobtained only from neonates with positive blood cultures on the 3rd (Day3), accordingly our patients divided into improved and deteriorated groups. Results There was a significant decrease in CRP level and increase in procalcitonin and pentraxin 3 levels in deteriorated group than improved group at baseline with p-value = 0.004, 0.016 and 0.019; respectively. Also, the study shows that there was a significant increase in CRP, procalcitonin and pentraxin 3 levels in deteriorated group than improved group after 3 days with p-value = 0.002, &amp;lt;0.001 and &amp;lt;0.001; respectively. Furthermore, in improved group, there was a significant decrease in the level of CRP, procalcitonin and pentraxin 3 after 3 days than at baseline with p-value = 0.001, &amp;lt;0.001 and 0.001; respectively. Also in deteriorated group, there was statistically significant increase in the CRP and pentraxin 3 levels after 3 days than at baseline in deteriorated group with p- value = 0.002 and 0.019; respectively while no change found in procalcitonin level. Conclusion Serum pentraxin 3 and procalcitonin levels seem to be promising prognostic markers in neonatal sepsis with higher sensitivity and specificity for procalcitonin than pentraxin at 3 days.
