Prognostic Relevance of the Lung Ultrasound Score: A Multioutcome Study in Infants with Respiratory Distress Syndrome.

OBJECTIVE: There is growing evidence for the usefulness of the lung ultrasound score (LUS) in neonatal intensive care. We evaluated whether the LUS is predictive of outcomes in infants with respiratory distress syndrome (RDS). STUDY DESIGN: Neonates less than 34 weeks of gestational age were eligible for this prospective, multicenter cohort study. The outcomes of interest were the need for mechanical ventilation (MV) at <72 hours of life, the need for surfactant (SF), successful weaning from continuous positive airway pressure (CPAP), extubation readiness, and bronchopulmonary dysplasia. Lung scans were taken at 0 to 6 hours of life (Day 1), on Days 2, 3, and 7, and before CPAP withdrawal or extubation. Sonograms were scored (range 0-16) by a blinded expert sonographer. The area under the receiver operating characteristic curve (AUC) was used to estimate the prediction accuracy of the LUS. RESULTS: A total of 647 scans were obtained from 155 newborns with a median gestational age of 32 weeks. On Day 1, a cutoff LUS of 6 had a sensitivity (Se) of 88% and a specificity (Sp) of 79% to predict the need for SF (AUC = 0.86), while a cutoff LUS of 7 predicted the need for MV at <72 hours of life (Se = 89%, Sp = 65%, AUC = 0.80). LUS acquired prior to weaning off CPAP was an excellent predictor of successful CPAP withdrawal, with a cutoff level of 1 (Se = 67%, Sp = 100%, AUC = 0.86). CONCLUSION: The LUS has significant predictive ability for important outcomes in neonatal RDS. KEY POINTS: · Lung ultrasound has significant prognostic abilities in neonatal RDS.. · Early sonograms (0-6 h of life) accurately predict the requirement for SF and ventilation.. · Weaning off CPAP is effective when the LUS (range 0-16) is less than or equal to 1..

Protocol for a multicenter, double-blind, randomized, placebo-controlled phase III trial of the inhaled ß2-adrenergic receptor agonist salbutamol for transient tachypnea of the newborn (the REFSAL trial).

Background: Transient tachypnea of the newborn (TTN), which results from inadequate absorption of fetal lung fluid, is the most common cause of neonatal respiratory distress. Stimulation of ß-adrenergic receptors enhances alveolar fluid absorption. Therefore, the ß2-adrenergic receptor agonist salbutamol has been proposed as a treatment for TTN. This study aims to evaluate the efficacy and safety of salbutamol as supportive pharmacotherapy together with non-invasive nasal continuous positive airway pressure (NIV/nCPAP) for the prevention of persistent pulmonary hypertension of the newborn (PPHN) in infants with TTN. Methods and analysis: This multicenter, double-blind, phase III trial will include infants with a gestational age between 32 and 42 weeks who are affected by respiratory disorders and treated in eight neonatal intensive care units in Poland. A total of 608 infants within 24 h after birth will be enrolled and randomly assigned (1:1) to receive nebulized salbutamol with NIV or placebo (nebulized 0.9% NaCl) with NIV. The primary outcome is the percentage of infants with TTN who develop PPHN. The secondary outcomes are the severity of respiratory distress (assessed with the modified TTN Silverman score), frequency of need for intubation, duration of NIV and hospitalization, acid-base balance (blood pH, partial pressure of O2 and CO2, and base excess), and blood serum ionogram for Na+, K+, and Ca2+. Discussion: The Respiratory Failure with Salbutamol (REFSAL) study will be the first clinical trial to evaluate the efficacy and safety of salbutamol in the prevention of persistent pulmonary hypertension in newborns with tachypnea, and will improve short term outcomes. If successful, the study will demonstrate the feasibility of early intervention with NIV/nCPAP together with nebulized salbutamol in the management of TTN. Ethics and dissemination: The study protocol was approved by the Bioethics Committee of the Medical University of Warsaw, Warsaw, Poland on November 16, 2020 (decision number KB/190/2020). All procedures will follow the principles of the Declaration of Helsinki. The results of the study will be submitted for knowledge translation in peer-reviewed journals and presented at national and international pediatric society conferences. Clinical Trial Registration: It is registered at ClinicalTrials.gov NCT05527704, EudraCT 2020-003913-36; Protocol version 5.0 from 04/01/2022.

Status of Oxidative Stress during Low-Risk Labour: Preliminary Data.

Pregnancy and childbirth are associated with the forming of reactive oxygen species that generate oxidative stress. Oxidative stress is a factor that may adversely affect the development of the fetus and the course of labour. Monitoring the parameters of oxidative stress can be used to assess the risk of health issues in the course of pregnancy and the condition of the newborn. Therefore, the analysis of oxidative stress in the physiological course of labour is the basis for understanding the role of oxidative stress in the pathogenesis of miscarriages and neonatal health circumstances. The study aimed to assess oxidative stress of mother-child pairs in the venous blood and umbilical cord blood at the time of physiological labour. One hundred and sixty-eight mother-child pairs were recruited to donate the mother's venous blood in the first stage of labour and the venous umbilical cord blood after the newborn's birth. Total antioxidant status (TAS), the activity of superoxide dismutase (SOD) with cofactors (Zn, Cu, Mn) and the activity of glutathione peroxidase (GPx) were analysed in venous blood plasma and umbilical cord blood. TAS value (p = 0.034), GPx activity (p < 0.001) and Zn concentration (p = 0.007) were significantly lower in maternal blood plasma as compared to neonatal umbilical cord blood. However, the activity of SOD (p = 0.013) and the concentration of Cu (p < 0.001) were significantly higher in the blood of mothers than of new-borns. The concentration of Mn in the plasma of the mother's blood and the umbilical cord blood of the newborns was similar. Our research indicates higher levels of antioxidant enzyme (GPx) and total antioxidant potential (TAS) in umbilical cord blood compared to maternal blood, which may suggest depletion of redox reserves in women's blood during labour.

Perception of Stress and Styles of Coping with It in Parents Giving Kangaroo Mother Care to Their Children during Hospitalization in NICU.

The experience of hospitalization of a newborn in the Neonatal Intensive Care Unit (NICU) may become distressing both for the baby and parent. The study aimed to assess the degree of parental stress and coping strategies in parents giving KMC to their babies hospitalized in NICU compared to the control group parents not giving KMC. The prospective observational study enrolled a cohort of 337 parents of premature babies hospitalized in NICU in 2016 in Eastern Poland. The Parental Stressor Scale: Neonatal Intensive Care Unit, Coping Inventory for Stressful Situations were used. The level of stress in parents giving KMC was defined as low or moderate. Analysis confirmed its greater presence in the group of parents initiating KMC late (2-3 weeks) compared to those starting this initiative in week 1 of a child's life. An additional predictor of a higher level of stress in parents initiating KMC "late" was the hospital environment of a premature baby. Task oriented coping was the most common coping strategy in the study group. KMC and direct skin-to-skin contact of the parent with the baby was associated with a higher level of parental stress only initially and decreased with time and KMC frequency.

Proteins Structure Models in the Evaluation of Novel Variant (C.472_477del) in the MOCS2 Gene.

(1) Background: Molybdenum cofactor deficiency type B (MOCODB, #252160) is a rare autosomal recessive metabolic disorder characterized by intractable seizures of neonatal-onset, muscular spasticity, accompanying with hypouricemia, elevated urinary sulfite levels and craniofacial dysmorphism. Thirty-five patients were reported to date. (2) Methods: Our paper aimed to delineate the disease genotype by presenting another patient, in whom a novel, in-frame variant within the MOCS2 gene was identified. (3) Results: Exome sequencing led to the identification of a novel variant in the MOCS2 gene-c.472_477del of unknown significance (VUS). (4) Conclusions: To prove the clinical significance of the mentioned variant, analysis of the possible mutation consequences on molecular level with the use of the available crystal structure of the human molybdopterin synthase complex was of great importance. Moreover, a potential pathomechanism resulting from a molecular defect was presented, giving original insight into the current knowledge on this rare disease, including treatment options.

Usefulness of ultrasound examinations in the diagnostics of necrotizing enterocolitis.

BACKGROUND: Necrotizing enterocolitis (NEC) is one of the most serious disorders of gastrointestinal tract during neonatal period. Early diagnosis and adequate treatment are essential in the presence of clinical suspicion of NEC. Plain abdominal radiography is currently the modality of choice for initial evaluation of gastrointestinal tract in neonates. However, when the diagnosis is uncertain, abdominal ultrasound with bowel assessment might be an important complementary examination. The aim of the study was to evaluate usefulness of ultrasound in the diagnosis of NEC and its value for implementation of proper treatment. MATERIAL/METHODS: The data of nine neonates diagnosed with NEC, hospitalized at the Provincial Hospital No. 2 in Rzeszow in the period from September 2009 to April 2013 was retrospectively analyzed. Apart from abdominal radiography, abdominal ultrasound with bowel assessment was performed in all nine cases. Imaging findings, epidemiological data, coexisting risk factors and disease course were assessed. RESULTS: Most children in the group were preterm neonates. Findings in plain abdominal radiography were normal or nonspecific. A wider spectrum of findings was demonstrated in all ultrasound examinations and intestinal pneumatosis, a pathognomonic sign for NEC, was more frequently noted than in plain abdominal x-ray. Most children were treated by surgical intervention with resection of necrotic bowel loops and in more than half of the cases location of changes identified during surgery was concordant with ultrasonographic findings. CONCLUSIONS: Abdominal ultrasound examination might be helpful in the diagnosis of NEC, especially when plain abdominal radiography findings do not correlate with clinical symptoms. However, abdominal radiography is still considered the modality of choice. The range of morphological changes detectable on ultrasound examination is much wider than in plain abdominal radiography. Ultrasound examination allows for more accurate assessment of changes within intestines and adjacent tissues, which aids clinicians in making more accurate therapeutic decisions and implementing proper treatment.

Early screening for critical congenital heart defects in asymptomatic newborns in Mazovia province: experience of the POLKARD pulse oximetry programme 2006-2008 in Poland.

BACKGROUND: Early diagnosis of critical congenital heart defects (CCHD) may be missed both during prenatal echocardiography and the short stay in the neonatal nursery, leading to circulatory collapse or death of the newborn before readmission to hospital. AIM: To assess the usefulness of pulse oximetry as a screening test in early diagnosis of CCHD in newborns. METHODS: A prospective screening pulse oximetry test was conducted in 51 neonatal units in the Mazovia province of Poland as part of the POLKARD 2006-2008 programme between 16 January, 2007 and 31 January, 2008. Newborns with no circulatory symptoms or coexisting diseases, and no prenatal diagnosis, were enrolled. The test was performed between the 2(nd) and 24(th) hours of life in stable newborns. A double arterial oxygen saturation (SpO(2)) reading < 95% on a lower extremity led to cardiovascular evaluation and echocardiography. RESULTS: From a population of 52,993 newborns (14.2% of births in Poland), a group of 51,698 asymptomatic infants was isolated. CCHD was diagnosed solely by pulse oximetry in 15 newborns, which constituted 18.3% of all CCHD; 14 (0.026%) false positives were obtained and there were four false negative results. The sensitivity of the test was 78.9% and specificity 99.9%. The positive predictive value was 51.7% and negative 99.9%. CONCLUSIONS: Pulse oximetry fulfilling the screening test criteria, performed on a large population of newborns in Poland, proved useful in supporting prenatal diagnostics and postnatal physical examination in the early detection of initially asymptomatic CCHD. Good sensitivity and specificity results of the pulse oximetry test have allowed it to be recommended for use in neonatal units nationwide.

[Congenitally corrected transposition of the great arteries with coexisting stenosis of pulmonary trunk valve and ventricular septum defect in a 55-year-old woman--a case report]. / Wrodzone skorygowane przelozenie wielkich pni tetniczych wspólistniejace ze stenoza zastawki pnia plucnego i ubytkiem czesci bloniastej przegrody miedzykomorowej u 55-letniej kobiety.

Congenitally corrected transposition of the great arteries (CCTGA) is a rare cardiac malformation. This anomaly is characterised by atrioventricular as well as ventriculoarterial discordance. Isolated CCTGA may cause no symptoms until adult life. Most CCTGA cases with concomitant cardiac abnormalities are symptomatic and are therefore usually diagnosed in childhood. In the majority of patients, congestive heart failure secondary to right ventricular dysfunction occurring by the fifth or sixth decade enables diagnosis. We present an oligosymptomatic 55-year-old woman with corrected transposition of the great arteries and coexisting stenosis of pulmonary trunk valve and ventricular septum defect.

Trends in diagnosis and prevalence of critical congenital heart defects in the Podkarpacie province in 2002-2004, based on data from the Polish Registry of Congenital Malformations.

This paper presents results of data collection regarding congenital heart defects (CHD) for the Polish Registry of Congenital Malformations (PRCM) from the Podkarpacie province in 2002-2004. Routine methods (fetal echocardiography, clinical examination) and recently also unique methods (screening echocardiography and pulse oximetry) were used for early detection of critical cardiac malformations. Critical CHD were detected there in 107 newborns in 2002-2004, so the mean prevalence reached 1.71/1000. Within this group, death rate decreased from 8 deaths in 2002 to 2 deaths in 2004, mainly thanks to improved detection and treatment of CHD.
