Abstract
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 β-adrenergic receptors enhances alveolar fluid absorption. Therefore, the β2-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.

Abstract
INTRODUCTION The task of contemporary neonatology is not only to save the lives of children born prematurely, but also to provide them with the highest possible quality of life. The Prechtl method, one of several methods of assessing the quality of general movement patterns, enables early identification of immaturity or damage to the central nervous system. AIM Dynamic assessment of the type and quality of general movement (GMs) in preterm infants to determine indications for early neurodevelopmental support and to identify the relationship between the occurrence of maternal and neonatal perinatal risk factors and the type and quality of general movements. MATERIAL AND METHOD 90 infants were assessed between 28 0/7 and 36 6/7 weeks gestational age. Dominant cases (57 cases) were infants born between 32 and 36 weeks GE. Most cases (48) received low Apgar score at 1 min (≤7), including two born in very severe condition. Neonatal infections were diagnosed in 26 infants. The study included three GM assessments: I - up to 14th day post-partum, II at term and III between 12 and 15 weeks corrected age. The analysis included gestational age, general condition of the newborn as per Apgar score as well as early and late infections. RESULTS Neonatal infections were found to show a close correlation with the occurrence of abnormal general movements. It was confirmed that gestational age and congenital infections are important variables affecting the occurrence of abnormal general movements.

Abstract
Aim Probiotic bacteria administered directly after birth to preterm neonates may improve gastrointestinal function and may reduce the incidence of late-onset sepsis, which is a frequent complication in this group. Purpose The main objective of this study was to evaluate whether a new probiotic bacterial mixture of Lactobacillus rhamnosus KL53A and Bifidobacterium breve PB04 given to preterm, low-birth-weight neonates would influence composition of their gut microbiota and sepsis rates. Patients and methods This study was a multicenter, randomized, double-blind, placebo-controlled trial conducted in clinical centers of neonatal care in Poland. A probiotic or placebo preparation was given twice daily to 181 preterm low-birth-weight neonates who were eligible for enteral feeding between July 2012 and July 2013. The probiotic was given to 90 neonates, while placebo was given to 91 neonates. The gut microbiota was monitored by microbiological analysis of stool samples. Sepsis episodes were detected on the basis of clinical and laboratory findings and confirmed by blood cultures. Results Tested probiotic administration resulted in continuous increase of the Lactobacillus and Bifidobacterium counts in the gut microbiota. The applied tested strains successfully colonized the neonates gut since they were present in over 90% of stool samples, which was confirmed by molecular analysis. Regardless of the study group (probiotic or placebo), B. breve colonization correlated with lower staphylococcal sepsis incidence, which was irrespective of whether probiotics were given. No sepsis case caused by strains included in study probiotic was recorded. Conclusion Appropriately selected and characterized probiotic bacteria may be safely given to preterm neonates to normalize their distorted gut microbiota and may contribute to lower staphylococcal sepsis rates.

Abstract
In the presented assay, we elaborated a method for distinguishing sequences that are genetically closely related to each other. This is particularly important in a situation where a fine balance of the allele abundance is a point of research interest. We developed a peptide nucleic acid (PNA) strand invasion technique for the differentiation between multiple sclerosis-associated retrovirus (MSRV) and ERVWE1 sequences, both molecularly similar, belonging to the human endogenous retrovirus HERV-W family. We have found that this method may support the PCR technique in screening for minor alleles which, in certain conditions, may be undetected by the standard PCR technique. We performed the analysis of different ERVWE1 and MSRV template mixtures ranging from 0 to 100% of ERVWE1 in the studied samples, finding the linear correlation between template composition and signal intensity of final reaction products. Using the PNA strand invasion assay, we were able to estimate the relative ERVWE1 expression level in human specimens such as U-87 MG, normal human astrocytes cell lines and placental tissue. The results remained in concordance with those obtained by semi-quantitative or quantitative PCR.

Abstract
Studies were conducted on samples taken from giving birth women (n = 40) living in Poland, representing three age groups: 19-25, 26-30 and 31-38 years old. Mercury concentrations were measured with CV-AAS in placenta, umbilical cord, cord blood and amniotic fluid. The placentas weight did not exceed the 750 g value and was heavier than 310 g. Mean values of Hg concentrations in blood, placenta and umbilical cord were similar (c.a. 9 μg/g). High levels of mercury were noted in cord blood which in 75% of all observations exceeded (up to 17 μg/L) the safe dose set by US EPA (5.8 μg/L). No statistically significant differences in medium level of Hg in all the studied tissues among age groups of women were observed. Positive correlations between Hg concentrations in placenta and umbilical cord and cord blood were revealed as well as some negative ones between mercury concentrations and pregnancy parameters.

Abstract
A germinal matrix is an area of the fetal brain where neuroblasts proliferate till the 20th week of gestation after which their migration takes place. Germinal matrix hemorrhage (GMH) is a frequent cause of fetal ventriculomegaly or hydrocephalus, yet the pathophysiological conditions of GMH remain unclear. A case of fetal ventriculomegaly resulting from GMH has been reported in the article. A prenatal ultrasonographic examination (US) carried out in the 30th week of gestation revealed enlarged ventricles. Utero magnetic resonance imaging (MRI) performed in the 34th week of gestation demonstrated asymetric ventriculomegaly and the changes suggesting the occurance of GMH and ependymal intraventricular hemorrhage. Fetal ventriculomegaly and hydrocephalus are commonly detected by ultrasonographic examination, but it is often difficult to determine the causes of the diseases by US. In these cases MRI allows to establish the final diagnosis.

Abstract
BACKGROUND AND AIM The aim of the study was to compare epidermal growth factor (EGF) concentration in 81 colostrum samples collected from mothers of newborns in the following growth categories: preterm appropriate for gestational age (AGA), preterm small for gestational age (SGA), and full term (FT). RESULTS Significantly higher concentrations of EGF were found in the colostrum of mothers who delivered premature AGA infants at less than 32 weeks of gestation compared with mothers who delivered premature SGA babies at the same gestational age. CONCLUSIONS We concluded that the maternal compensatory mechanism accelerating the development of immature breast-fed infants may be disturbed when gestation is complicated by intrauterine growth retardation.

Abstract
OBJECTIVES Toxoplasma gondii infection during pregnancy is still a difficult problem in the contemporary perinatology. Difficulties met during interpretation of serological tests carried out in pregnant patients to detect Toxoplasmosis implies more and more frequent use of the Polymerase Chain Reaction (PCR). DESIGN To evaluate the dependence between serological tests and quantity of the Toxoplasma gondii genomes in mothers' blood and amniotic fluid or neonatal blood, the quantitative PCR (q-PCR) method was applied. MATERIALS AND METHODS The analysis was performed in 81 pregnant women. Maternal blood, amniotic fluid and newborns' umbilical blood samples were evaluated for the presence of Toxoplasma gondii DNA. IgG and IgM Toxoplasma gondii antibodies were evaluated by the ELISA method. RESULTS High seroprevalence (51.9%) of the Toxoplasma gondii was confirmed. Toxoplasma gondii genetic material in blood and/or amniotic fluid was found in 33 patients. It was stated that quantity of the protozoa and anti-IgM presence in mothers' blood are the factors influencing significantly the Toxoplasma gondii manifestation in amniotic fluid. CONCLUSION High suitability of PCR in diagnosis of Toxoplasmosis during pregnancy and vertical transmission was confirmed.

Abstract
Routine serological diagnosis of toxoplasmosis provides high sensitivity, but not high specificity. The high sensivity combined with high specifity offered by PCR-TaqMann as well as the degree of infection led us to investigate the presence and levels of T. gondii DNA in amniotic fluid, maternal and neonatal blood in cases of pregnancy where infection with this agent was suspected. Samples of amniotic fluid and blood were taken from pregnant women. Postnatal blood samples were also taken from their infants. Presence and levels of toxoplasma DNA was investigated using PCR-TaqMann. PCR products were detected by electrophoresis on polyacrylamide gel. The PCR-TaqMann test is highly sensitive, specific and useful method allowing detection of the parasite genome and assessement of its level.

Abstract
Prenatal screening of Toxoplasma gondii infection is controversial. The diagnosis is based on serological tests detecting IgM and IgG antibodies against T. gondii, but interpretation of these tests results is often confusing. It is commonly made retrospectively when serological screening indicates a possibility of recent infection. Most women have antibodies against T. gondii and serial testing is required only in monitoring of pregnancies where initial screening is negative. The introduction of Polymerase Chain Reaction (PCR) assay for detection of Toxoplasma gondii DNA in selected cases of pathologic pregnancies has permitted a more accurate and faster diagnosis of congenital toxoplasmosis infections.

Abstract
UNLABELLED Routine serological diagnosis of Toxoplasmosis provides high sensitivity, but not high specificity. The high sensitivity combined with high specificity offered by PCR-TaqMan as well as the degree of infection led us to investigate the presence and levels of Toxoplasma gondii genome in amniotic fluid, maternal and neonatal blood in cases of pregnancy where infection with this agent was suspected. MATERIALS AND METHODS Samples of amniotic fluid and blood were taken from 28 women between the 16th and 40th week of gestational age. Postnatal blood samples were also taken from their infants. Included in the study group were women with IUGR, PROM, preterm delivery imminent, Toxoplasmosis in previous pregnancies, raised IgG or IgM anti-Toxoplasma antibody titers and with amniotic fluid disturbances (oligohydramnios and polyhydramnios). Presence and levels of Toxoplasma genome was investigated using PCR-TaqMan. PCR products were detected by electrophoresis on polyacrylamide gel. RESULTS Toxoplasma gondii genome was detected in blood from 13 women, 3 newborns and in amniotic fluid from one other women. Toxoplasma genome was detected in blood from one newborn, but was not detected in sample from its mother. CONCLUSIONS The PCR-TaqMan test is highly sensitive and specific method allowing detection of the parasite genome and assessment of its level. Limitations of this method are its relatively high cost and poor access to ABI PRISM 7700 (TaqMan) sequence detector. The PCR TaqMan is useful in cases, where serological tests for the presence of infections are ambiguous.

Abstract
Fetal ascites may be caused by different abnormalities. Determining of the cause is very important in terms and the way of treatment. Some cases may require immediate interaction. We presented fetal ascites with atresio intensive with intrauterine perforation--the way of diagnosis and success of therapy.
