Abstract
OBJECTIVE Introduction: Due to specific anatomy of children are more vulnerable to the carcinogenic effects of ionizing radiation from chest X-rays. Lung ultrasound (LUS) is a validated procedure which can easily be used in diagnosing pathologies of the neonatal lung. However, experimental studies have shown that low frequency ultrasound may induce pulmonary capillary hemorrhage (PCH). Aim of the study: To evaluate the potential relationship between lung ultrasound and pulmonary hemorrhage in very low birth weight infants. PATIENTS AND METHODS Patients and methods: We analysed the medical records of very low birth weight infants admitted to our neonatal tertiary centre between 2008 and 2011 (group 1), when CXR was the main procedure used to evaluate the respiratory system, and between 2013 and 2016 (group 2), when LUS became a routine procedure, replacing the chest X-ray. RESULTS Results: 297 infants were enrolled in the first group and 286 in the second group, respectively. There was no difference in the frequency of pulmonary hemorrhages between the two groups (p=1). In the first group there was only one episode of PCH and in the second group no PCH was seen. Statistically significant differences were seen in a number of patients with pulmonary hemorrhage risk factors: surfactant administration (p<0.001), mechanical ventilation (p=0.0003), and hemodynamically significant patent ductus arteriosus (p=0.025). CONCLUSION Conclusions: Routine lung ultrasound appears to be safe in very low birth weight infants; there were no episodes of pulmonary hemorrhage.

Abstract
BACKGROUND Immature immune systems predispose very low birth weight (VLBW) neonates to systemic infections in early life. Defective inflammasome function may increase a neonate's susceptibility to late-onset sepsis (LOS). METHODS Blood samples were taken on the 5th day of life (DOL) for all VLBW neonates (non-LOS and before-LOS groups; N.=76), and within 24 hours of sepsis onset (LOS group; N.=39). Monocyte (MO) subsets and intracellular interleukin-1β (IL-1β) expression were analyzed using flow cytometry. Inflammasome function, defined as level of IL-1β and interleukin-18 (IL-18) was measured with enzyme-linked immunosorbent assay. IRA B cells were reported as a fraction of all B cells. RESULTS Stimulation of classical MO in non-LOS cells demonstrated a higher expression of intracellular IL-1β in comparison to MO from before LOS group. Serum from the LOS group revealed a higher level of IL-18. Stimulation of mononuclear cultures from samples taken during LOS resulted in significantly increased supernatant level of IL-1β and IL-18 in comparison to samples taken on 5th DOL. No changes in the levels of IRA B cells were detected with the onset of sepsis. CONCLUSIONS We did not observe a difference in the functioning of the inflammasome within monocytes taken on 5th DOL from premature VLBW neonates. Furthermore, there was no observable change in the IRA B cells of the septic and non-septic groups. The decreased expression of intracellular IL-1β within classical MO of the before-LOS group may be an independent risk factor for LOS development.

Abstract
INTRODUCTION Retinopathy of prematurity (ROP) is one of the leading avoidable causes of blindness in childhood in developed countries. Accurate diagnosis and treatment are essential for preventing the loss of vision. WINROP (https://www.winrop.com) is an online monitoring system which predicts the risk for ROP requiring treatment based on gestational age, birth weight, and body weight gain. AIM To validate diagnostic accuracy of the WINROP algorithm for the detection of severe ROP in a single centre cohort of Polish, high-risk preterm infant population. MATERIAL AND METHODS Medical records of neonates born before 32 weeks of gestation admitted to the third level neonatal centre in a 2-year retrospective investigation 79 patients were included in the study: their gestational age, birth weight and body weight gain were set in the WINROP system. The algorithm evaluated the risk for ROP divided into low or high-risk of disease and identified infants with high risk of developing severe ROP (type 1 ROP). RESULTS Out of 79 patients 37 received a high-risk alarm, of whom 22 developed severe ROP. Low-risk alarm was triggered in 42 infants; five of them developed type 1 ROP. The sensitivity of the WINROP was found to be 81.5% (95% CI 61.9-93.7), specificity 71.2% (95% CI 56.9-82.9), negative predictive value (NPV) 88.1% (95% CI 76.7-94.3), and positive predictive value (PPV) 59.5 (95% CI 48.1-69.9), respectively. The accuracy of the test significantly increased after combined WINROP and surfactant therapy as an additional factor - sensitivity 96.3% (95% CI 81.0-99.9), specificity 63.5% (95% CI 49.0-76.4), NPV 97.1% (95% CI 82.3-99.6), and PPV 57.8 (95% CI 48.7-66.4). CONCLUSIONS The WINROP algorithm sensitivity from the Polish cohort was not as high as that reported in developed countries. However, combined with additional factors (e.g. surfactant treatment) it can be useful for identifying the risk groups of sight-threatening ROP. The accuracy of the WINROP algorithm should be validated in a large multi-center prospective study in a Polish population of preterm infants.

Abstract
AIM To continue the prospective follow-up cohort study on the somatic development and lipid metabolic parameters of 11-year-old-children born with extremely low birth weight and to compare them with the results obtained in the study of 7-year-old children from the same group. MATERIAL AND METHODS 204 newborns with birth weight ≤1000 g were born in the Malopolska voivodship between 1.09.2002 and 31.08.2004. From this group 115 (56%) children died during infancy and 89 (44%) infants survived. At the age of 7 years 81 (91%) of the children from this group were examined. At the age of 11 years investigations were carried out in 62 (75%) of the children, while 19 (26%) were lost to follow-up. All the children underwent anthropometric measurements. Moreover, the lipid profile (serum total cholesterol, triglycerides, HDL-cholesterol, LDL cholesterol) was evaluated. The control group consisted of 36 children born at term chosen randomly from the general population and matched with regard to age and sex. RESULTS Children born with extremely low birth weight were generally smaller than their peers. At 7 years, they were shorter (113.75 cm(-0.72) vs.124.52 cm(0.53)), lighter (19.47 kg(-1.12)vs.25.23 kg(0.39)), had a smaller head circumference (49.81 cm(-2.19) vs.52.5 cm(-0.377)), waist circumference (50.14 cm(-0.83) vs.55.45 cm (0.34)), mid-upper arm circumference (17.51 cm vs. 19.29 cm), skinfold thickness (0.76cm(-0.817) vs.0.92cm (-0.19)) and body mass index (14.5 kg/m2 (-0.99)vs.16.16 kg/m2 (0.12)) expressed both as absolute values and z-score values compared to the control group. At 11 years old, the height (141.7 cm(-0.368) vs.146.26 cm(0.65)), weight (33.88 kg (-0.59)vs.40.45 kg(0.66)), head circumference (51.37 cm(-2.05)vs.54.02 cm(-0.33)), waist circumference (61.7 cm (0.26) vs.67.84 cm(1.06)), mid-upper arm circumference (20.95 cm vs. 22.85 cm), skinfold thickness (1.17 cm(-0.25)vs.1.68 cm(0.78)) and body mass index (16.74 kg/m2 (-0.62) vs.18.72 kg/m2 (0.36)) expressed both as absolute values and z-score values were still lower in children born with extremely low birthweight than in the control group. However, their gains over the time period between 7 and 11 years were comparable to their born-at-term peers in all the measured anthropometric parameters. There were no statistically evident differences in the indices of lipid metabolism. CONCLUSIONS Preterm children with extremely low birth weight (<1000 g) are at an increased risk of growth failure. Once they reach teenage years they are shorter and lighter than their age- and sexmatched born-at-term peers. They also have smaller heads. In our study we did not find statistically evident differences between the investigated and control group in lipid indices. There is a need for longitudinal studies to observe somatic, mental and metabolic development in order to organize multidisciplinary holistic medical care for them.

Abstract
BACKGROUND Careful control of glucose homeostasis is essential for infants with very low birth weight (VLBW). In clinical practice, blood and urine glucose levels are monitored; however, their correlation has not been fully investigated in VLBW infants. OBJECTIVES To evaluate the correlation between interstitial fluid glucose concentration (ISFG), glycosuria, and urine output among VLBW infants through continuous glucose monitoring (CGM). METHODS A prospective, single-center, open cohort study enrolled 74 VLBW infants with a mean birth weight of 1,066 g. CGM (Guardian Real-Time CGM®; Medtronic, Northridge, CA, USA) was used to measure glucose. The urine output was calculated using 4-hour intervals. Reagent strips were used for semiquantitative measurement of glycosuria. RESULTS The CGM delivered 102,334 glucose measurements. 2,684 urine samples were checked for glycosuria, of which 92.06% remained negative. Corresponding glycemia in samples without glycosuria remained normoglycemic (median 103 mg/dL; 10-90th percentile 80-144 mg/dL). The median glucose concentrations for samples in ascending glycosuria categories 1+, 2+, 3+, and 4+ were 152, 181, 214, and 222 mg/dL, respectively. A moderate correlation between ISFG and urine output was found for categories ≥1+ (rs = 0.56; 95% confidence interval 0.42-0.68; p < 0.001). The urine output was significantly lower when glycosuria was absent (p < 0.05). Polyuria was observed only in glycosuria 4+ (median urine output 9.9; interquartile range 7.4-12.2 mL/kg/h). CONCLUSIONS The renal glucose threshold in VLBW infants is between 150 and 180 mg/dL. A negative result for glycosuria is a reliable screening test to exclude hyperglycemia. Occurrence of glycosuria ≥1+ is an indication to test blood glucose.

Abstract
Programmed death-1 (PD-1) receptor system represents a part of recently reported immunoregulatory pathway. PD-1 is an immune checkpoint molecule, which plays an important role in downregulating the immune system proinflammatory activity. Until recently, PD-1 expression was not established on immune cells of the preterm infants. The study objectives were to confirm expression of the PD-1 receptors on the monocytes isolated from very low birth weight newborns (VLBW), and to analyze their expression during the first week of life and late-onset sepsis. Peripheral blood mononuclear cells were isolated from 76 VLBW patients without early-onset sepsis on their 5th day of life (DOL). PD-1 expression was determined on the monocyte subsets (classical, intermediate, non-classical) by flow cytometry. In case of late-onset sepsis (LOS), the same analysis was performed. Our results demonstrated that on the 5th DOL, PD-1 receptors were present in all the monocyte subsets. Children, whose mothers had received antenatal steroids, presented higher absolute numbers of non-classical monocytes with PD-1 expression. Infants born extremely preterm who later developed LOS, initially showed a lower percentage of PD-1 receptor-positive intermediate monocytes in comparison to neonates born very preterm. During LOS, we observed a rise in the percentage of classical monocytes with PD-1 expression. In case of septic shock or fatal outcome, there was a higher percentage and absolute count of intermediate monocytes with PD-1 expression in comparison to children without these complications. In conclusion, monocytes from VLBW children express PD-1 receptors. Antenatal steroid administration seems to induce PD-1 receptor expression in the non-classical monocytes. PD-1 might play a role in immunosuppressive phase of sepsis in the prematurely born children with septic shock and fatal outcome.

Abstract
BACKGROUND Inflammasomes regulate activation of caspase-1, which cleaves and activates interleukin (IL)-1β and IL-18, the cytokines that trigger pro-inflammatory and antimicrobial responses. There is very little known about inflammasome function in the subsets of monocytes (MO) isolated from preterm neonates born extremely and very prematurely. METHODS A group of 76 very low birth weight patients without early-onset sepsis was divided into extremely preterm (<28 gestational week) or very preterm (28-32 gestational week) neonates. The first blood sample was collected on the 5th day of life (5th DOL) to analyse MO subsets as well as the intracellular IL-1β expression and supernatant concentration of IL-1β and IL-18. Secondary blood samples were collected within 24h of late-onset sepsis (LOS) development and analysed as above. RESULTS On the 5th DOL, the extremely preterm neonates were characterized by a significantly higher absolute count of MO, in particular in the classical and intermediate subsets, as compared to the very preterm group. The counts of the intermediate and non-classical MO subsets increased during LOS in all neonates. We did not observe significant differences in the intracellular IL-1β expression between the analysed groups. Furthermore, the levels of the analysed cytokines in the MO supernatants were comparable between the extremely and very preterm neonates on the 5th DOL. Finally, a higher level of IL-18 was observed in the supernatant of the extremely preterm group during LOS. CONCLUSIONS During LOS, extremely preterm neonates excrete a higher level of IL-18 cytokines compared to very preterm neonates. Further studies are required to determine whether this observation is a result of a higher count of the circulating MO or is a true reflection of increased inflammasome function in this particular group of newborns.

Abstract
PURPOSE Renal injury in term and pre-term neonates may be an antecedent to chronic kidney disease in the child's further life. The aim of the paper was to compile a reference range for selected serum and urinary renal markers in the neonatal period for full-term (FT) and pre-term (PT) newborns. MATERIAL AND METHODS The prospective study included 23 FT infants (birth weight - BW≥2500g and gestational age - GA≥37Hbd) and 32 PT children (BW<2500g and GA<37Hbd) in good general condition, without acute kidney injury (AKI) or sepsis. Between the 4th and 28th DOL, urinary concentrations of the studied renal markers (uCr, uNa, uOsm) were determined on a daily basis, while serum creatinine (SCr) was assessed minimum every 48-72h. RESULTS The mean GA and BW of the FT and PT infants were respectively as follows: 38.5±1.7Hbd; 3433±495.2g and 32.7±2.6Hbd; 1836.7±419.8g. For serum glomerular (SCr, eGFR) and tubular markers (FENa, RFI), the median values with normal ranges were compiled. For urinary renal markers (uCr, uNa, uOsm) and those values standardized for kg of body weight, percentile tables for 4-28DOL were elaborated. CONCLUSIONS The study has resulted in determining the normal ranges of serum glomerular and tubular renal markers, as well as percentile tables of selected urinary renal parameters during the neonatal period. The percentile tables may prove to be helpful for further standardization of other urinary parameters per urinary creatinine in neonatal population.

Abstract
BACKGROUND Bronchopulmonary dysplasia (BPD) remains a significant long-term complication of prematurity. A standardized method of pulmonary function testing is still not available in preschool children with BPD. We investigated the feasibility of Electrical Impedance Segmentography (EIS) monitoring in this group and the impact of bronchodilator response (BDR) to salbutamol on the pattern of lung ventilation. METHODS We conducted a follow-up study of 4-year-old premature children who had been treated in the tertiary NICU. The cohort was divided into two groups based on the presence of BPD. EIS monitoring was performed before and 15 min after the administration of 400 µg of salbutamol (pMDI with spacer) in all subjects during spontaneous tidal breathing in upright position. Data were expressed as median segmental impedance amplitude differences and segmental ventilation inhomogeneity index (II) changes. RESULTS We included 51 children in our analysis: 33 with BPD (median birth weight-840 g; median gestational age-27 weeks) and 18 without BPD (1,290 g; 30 weeks, respectively). There was a significant increase in median segmental impedance amplitude after salbutamol in gravity non-dependent segments in children with BPD: upper left (UL): 462 versus 534 AU; (P = 0.003); upper right (UR): 481 versus 595 AU (P < 0.001) and II in these segments: UL: 0.046 versus 0.078 (P = 0.003) UR: 0.049 versus 0.064 (P = 0.006). There were no changes in the lower segments. There were no changes in ventilation pattern in children without BPD. CONCLUSION BDR to salbutamol increases breath amplitude in gravity non-dependent segments of the lungs during spontaneous tidal breathing in preschool children with BPD.

Abstract
PURPOSE The aim of the study was to assess functional and structural ophthalmologic outcomes in 4-year old very low birth weight children (VLBW). MATERIAL AND METHODS A group of 82 VLBW children including: (1) children without retinopathy of prematurity – group O (n = 30), (2) children with retinopathy of prematurity with no indications for laser coagulation- group 1 (n = 20 ), (3) children with retinopathy of prematurity treated with laser coagulation – group 2 (n = 32) were enrolled. Functional (visual acuity, visual evoked potentials, stereopsis, color vision test) and structural (anterior eye segment examination and fundoscopy) outcome, cycloplegic refraction, intraocular pressure and angle of squint were examined in all children. Developmental Test of Visual Perception was also assessed. RESULTS Very good visual acuity was presented in 56 (68.3%) patients, good visual acuity in 11 (13.4%) children, visual acuity between 0.4 and 0.2 in 13 (15.9%) and unfavorable function (equal or less than 0.1) was observed in 2 (2.4%) children. Twenty-three patients (28.1%) were myopic, 57 patients (69.5%) were hyperopic. Astigmatism > 1D occurred in 49 (59.8%) patients. Anisometropia larger than 2 D occurred in 7 patients (8.7%). There was no statistical difference between frequency of mentioned above complications between the groups. Abnormal VEP results were more common (14 children -54%) in group 2 as compared to other groups (group 0 - 7 children -25%, group 1 – 4 children -24%; p = 0.044). Moreover, the lower percentage of group 2 children presented stereopsis vision (46.9%, group 0 – 93.3%, group 1 – 90%; p<0.05). Children with retinopathy of prematurity treated with laser coagulation had significantly lower Developmental Test of Visual Perceptions scores. In group 1, in 1 child naevus pigmentosus of the eyelid was observed, in group 2 in one child eyeball atrophy in the right eye and aphakia in the left eye were diagnosed. In 1 child in group 0 optic disc drusen were observed, in 2 children optic discs were pale. In 2 children in group 2 retinal detachment stage 5 was diagnosed. CONCLUSION An important factor affecting final ophthalomolgical assessment in prematurely born children is retinopathy of prematurity treated with laser coagulaion. Children with retinopathy of prematurity without laser coagulation had examinations results comparable wih children without retinopathy of prematurity. Diode laser photocoagulation is an effective method of treatment fot active stages of retinopathy of prematurity.

Abstract
OBJECTIVES The aim of the study was to assess emotional functioning and identification of temperamental traits in 4-year-old children born prematurely with birth weight =< 1500 grams. The second aim was evaluation of autism spectrum disorders frequency in this group of children. METHODS Eighty-six 4-year-old children born prematurely (gestational age =< 32 weeks, birth weight =< 1500 grams) were evaluated. All children underwent physical examination (with the assessment of motor function, vision and hearing), anthropometric measurements and psychomotor tests: Leiter International Performance Scale P-93, Children Vocabulary Test (TSD), temperament questionnaire (EAS-C), and CAST questionnaire. Parents were asked to fill in questionnaires assessing socio-economic conditions of the family and children attendance in kindergarten or early development support. RESULTS In the EAS-C questionnaire hyperactivity and reduced emotionality were significantly more common comparing to population. Children with lower gestational age and lower birth weight were characterized with low emotionality score. Children with the CAST score ? 12 points were significantly smaller at birth, more often suffered from retinopathy of prematurity and had poorer results in neurodevelopmental tests - Leiter scale, Children Vocabulary Test. CONCLUSIONS Children born prematurely are at greater risk of the occurrence of hyperactivity and autism spectrum symptoms. Detection of emotional disorders in children born prematurely is essential to implement the therapeutic support as early as possible.

Abstract
The KIF5A gene (OMIM 602821) encodes a neuron-specific kinesin heavy chain involved in intracellular transport of mitochondria and other cargoes. KIF5A protein comprises the N terminal motor domain, the stalk domain and the C-terminal cargo binding domain. The binding between KIF5A and its cargoes is mediated by kinesin adaptor proteins such as TRAK1 and TRAK2. Numerous missense KIF5A mutations in the motor and stalk domains cause spastic paraplegia type 10 (SPG10, OMIM 604187). Conversely, the role of loss-of-function mutations, especially those affecting the cargo binding domain, is unclear. We describe a novel de novo KIF5A p.Ser974fs/c.2921delC mutation found by whole exome sequencing in a patient with a congenital severe disease characterized by myoclonic seizures and progressive leukoencephalopathy. Since this phenotype differs considerably from the KIF5A/SPG10 disease spectrum we propose that the KIF5A p.Ser974fs and possibly other mutations which lead to truncation of the C-terminal tail of the protein cause a novel disorder. We speculate that the unique effect of the C-terminal truncating KIF5A mutations may result from the previously described complex role of this protein domain in binding of the TRAK2 and possibly other kinesin adaptor protein(s).

Abstract
BACKGROUND The aim of our study was multifaceted neurodevelopmental examination of children born prematurely with very low birth weight (VLBW) in order to evaluate the usefulness of popularly used tests. The second aim of the study was exploration of risk and protective factors of neurodevelopmental impairment. METHODS Eighty-nine VLBW patients were evaluated at the age of 50 months. All children underwent anthropometric measurements and psychomotor tests: functional independence measure scale (WeeFIM), Gross Motor Function Measurement (GMFM), non-verbal psychometric evaluation (Leiter test), Developmental Test of Visual Perception (DTVP-2), temperament questionnaire (EAS-C) and children vocabulary test (TSD). RESULTS Most severe deficits in ex-preterms' neurodevelopment were associated with verbal abilities, visual perception and temper abnormalities. WeeFIM, DTVP-2, Leiter and vocabulary tests' results correlated with each other. The lowest percent of children with deficits in WeeFIM test indicates, that it seems to be the most valuable tool for identification of the most seriously impaired children. Due to the highest percent of children with visual perception deficits, DTVP test seems to be good second choice in assessment of children born prematurely. In motor assessment GMFM appears to be more adequate than cerebral palsy (CP) diagnosis. Almost one fifth of VLBW did not reach 85% in Gross Motor Function Measurement, although only 9% of children had CP. CONCLUSIONS Children born with VLBW had deficits in every part of psychometric evaluation. We believe that the most useful tests in assessment VLBW patients are WeeFIM, GMFM and DTVP. Children with severe prematurity complications could require more precise evaluation.

Abstract
Very low birth weight is associated with long term neurodevelopmental complications. Macroscopic brain abnormalities in prematurity survivors have been investigated in several studies. However, there is limited data regarding local cerebral metabolic status and neurodevelopmental outcomes. The purpose of this study was to characterize the relationship between proton magnetic resonance spectra in basal ganglia, frontal white matter and frontoinsular gray matter, neurodevelopmental outcomes assessed with the Leiter scale and the Developmental Test of Visual Perception and selected socioeconomic variables in a cohort of very low birth weight children at the age of four. Children were divided in three groups based on the severity of neurodevelopmental impairment. There were no differences in spectroscopy in basal ganglia and frontal white matter between the groups. Lower concentrations of N-acetylaspartate (NAA), choline (Cho) and myoinositol (mI) were observed in the frontoinsular cortex of the left hemisphere in children with neurodevelopmental impairment compared to children with normal neurodevelopmental outcomes. Higher parental education, daycare attendance and breastfeeding after birth were associated with more favorable neurodevelopmental prognosis, whereas rural residence was more prevalent in children with moderate and severe impairment. Our study demonstrates the role of long term neurometabolic disruption in the left frontoinsular cortex and selected socioeconomic variables in determination of neurodevelopmental prognosis in prematurity survivors.

Abstract
Background Several research trials have analyzed the impact of prematurity on the prevalence of hypertension (HT). However, prospective long-term studies are lacking. Objectives The aim of this study was to evaluate the prevalence of HT at the age of 7 and 11 years in a regional cohort of preterm infants with a birth weight of ≤ 1000 g. Patients and Methods This study included 67 children with a birth weight of ≤ 1000 g who were born in Malopolska between September 2002 and August 2004. The control group consisted of 38 children born at term, matched for age. Each child underwent 24-h ambulatory blood pressure measurement (ABPM) twice, once at the age of 7 and again at 11 years. The presence of HT was estimated according to the mean arterial pressure (MAP) and a number of individual measurements. Results At aged 7 years, preterm infants had a significantly higher incidence of HT, defined on the basis of MAP (15% vs. 0%; P < 0.02) and on the percent of individual measurements (56% vs. 33%, P < 0.036). After taking into account the group of patients who received anti-HT treatment after the first part of the study, the incidence of HT at the age of 11 years based on MAP was 19% vs. 10%. Based on the individual measurements, it was 36.5% in the preterm infants vs. 24% in the control group. The differences were not statistically significant. At both time points, the preterm group had a higher mean heart rate (HR) than the control group. Conclusions Children born prematurely are predisposed to HT in later life, in addition to the persistence of an increased HR.

Abstract
OBJECTIVES The aim of this study was to establish reference intervals for urine sediment in newborns and infants in the second month of life for the UriSed automated analyser and for bright field microscopy. We also aimed to provide an optimal protocol for UriSed analysis, which best corresponds to the results of manual microscopy. DESIGN AND METHODS Urine sediment analyses of 75 healthy newborns and infants in the second month of life were performed by manual microscopy and UriSed automated analyser (two modes: 15 and 20 images per sample). Images were then reviewed and manually corrected by an operator when needed. RESULTS We observed statistically significant differences between bright-field microscopy and UriSed (when manual correction was not performed) for squamous epithelial cells and red blood cells counts (P<0.0001). There were no differences based on the number of images per sample (P>0.05). Upper reference values for bright-field microscopy and UriSed analyser taking 15 images per sample with manual correction (method we recommend) were as follows: squamous epithelial cells: microscope 8.7×10(6)/l, UriSed 6.4×10(6)/l, non-squamous epithelial cells: microscope 4.3×10(6)/l, UriSed 3.9×10(6)/l; erythrocytes: microscope 5.9×10(6)/l, UriSed: 4.6×10(6)/l; leukocytes: microscope 8.6×10(6)/l, UriSed 9.9×10(6)/l; hyaline casts: microscope 0×10(6)/l, UriSed (no correction) 0.7×10(6)/l. CONCLUSIONS We established preliminary reference intervals for urine sediment analysis in newborns and infants for UriSed and bright-field microscopy. We concluded that for routine laboratory examination of non-pathological urine it is enough to use the faster mode, with 15 images per sample, followed by a manual correction.

Abstract
BACKGROUND There are a lack of studies describing a longitudinal association between preterm delivery and renal complications later in life. We assessed renal size and function in preterm infants born with extremely low birth weight (ELBW) during 4 years of follow-up, comparing these parameters to age-matched children born full term (term controls). METHODS The results of selected renal laboratory tests [levels of cystatin C, creatinine, blood urea nitrogen (BUN)] and of renal ultrasound evaluations were compared between the ELBW group and the term control group at age 7 and 11 years. RESULTS The study population consisted of 64 children born with ELBW (ELBW children) who had been recruited at birth and 36 children born at term (term children) who took part in both follow-up assessments. Renal ultrasound examination revealed a significantly smaller renal volume in the 7- and 11-year-old ELBW children compared to the term controls [right kidney volume: 50.8 vs. 61.2 ml/m(2), respectively, at 7 years (p <0.01) and 51.4 vs. 58.2 ml/m(2), respectively, at 11 years (p <0.01); left kidney volume: 51.4 vs. 60.3 ml/m(2), respectively, at 7 years (p <0.01) and 55.2 vs. 60.7 ml/m(2), respectively, at 11 years (p = 0.02)]. Renal function in ELBW children was also affected. Serum cystatin C levels were significantly higher in ELBW children than in the controls at 7 years of age, and this difference remained statistically significant at 11 years of age [0.63 vs. 0.59 mg/l, respectively, at 7 years (p = 0.02) and 0.72 vs. 0.61 mg/l, respectively, at 11 years (p = 0.01)]. Six ELBW children also had elevated cystatin C levels (0.97-1.11 mg/l) at 11 years of age. Cystatin C levels were within normal range in the ELBW children at age 7 years and in term children in both follow-up studies. BUN levels were higher in ELBW children at the age of 11 years (4.49 vs. 4.15 mmol/l; p = 0.028). CONCLUSION Continued follow-up of these patients will reveal whether the observed worsening in renal function will persist into adulthood.

Abstract
INTRODUCTION Hypertension (HT) is one of the major risk factors of chronic kidney disease (CKD) progression and cardiovascular complications. The aim of the study was to analyze blood pressure (BP) values and assess the usefulness of clinical measurements in BP monitoring in children with chronic kidney disease. MATERIAL AND METHODS The study was conducted in 62 children (40 boys and 22 girls) aged 4,2-18,6 years (median age 12.4 (9.1; 16.0) with CKD stages 1 + 2 (n = 9), 3 (n = 17), 4 (n = 15) and 5. Creatinine concentration was measured and glomerular filtration rate was calculated using the Schwartz formula. Each of the patients underwent clinical BP measurements and 24-hour ambulatory blood pressure monitoring (ABPM). RESULTS Based on clinical meaurements elevated BP values were found in 25 patients (40.3%): in stages 1 + 2 in 33.3%, in stage 3 in 41.2%, in stage 4 in 46.6% and in stage 5 in 38.1% patients. Hypertension was diagnosed with ABPM in 30 patients (48.4% of the studied population): in stages 1 + 2 - 3 patients (33.3%), in stage 3 - 8 patients (47, 1%), in stage 4 - 7 patients (46.7%) and stage 5 - 12 patients (57.1%). Only 12 patients (19.4%) had hypertension diagnosed in both clinical and ABPM measurements. White coat effect was found in 13 children (21.0%) and masked HT in 18 children (29.0%). In 24-hour BP monitoring the highest values of systolic, diastolic and mean BP values were found in children with masked HT. In children with masked HT higher values of 24-hour systolic (120 vs. 105.5 mmHg, p<0.001) and diastolic (75 vs. 65 mmHg, p<0.001) BP compared with clinical values were detected. Children with masked HT had significantly higher nighttime diastolic BP compared with children with HT (1.43 vs. 0.74 z-score, p<0.001). CONCLUSIONS The large percentage of children with masked hypertension is an indication for frequent ABPM measurements in children with chronic kidney diseses. Office measurements are not sufficient to detect HT in children with CKD. The best diagnostic method to confirm and monitor hypertension in patients with CKD is 24-hour ambulatory blood pressure monitoring.

Abstract
BACKGROUND Children born with extremely low birth weight (ELBW) have more respiratory tract complications during childhood. Little is known about respiratory and allergy problems in ELBW children at the threshold of adolescence. MATERIALS AND METHODS A follow-up study was conducted at the age of 11 among ELBW children (n=65) and age-matched controls (n=36). The primary outcomes in the study were the occurrence of respiratory and allergy problems and the rate of hospitalization due to respiratory complications at the age of 11 years, assessed with a questionnaire. Secondary outcome variables were serum levels of immunoglobulin classes. RESULTS ELBW children had more respiratory tract infections (31 vs.11%, p = 0.03), but less allergies (3 vs. 22%, p < 0.01) compared with controls and had lower level of serum tIgE (geometric mean: 46.5 vs. 89.3 kU/l, p = 0.02). The risk factors for the occurrence of respiratory tract disorders in the ELBW group were: low gestational age, need for surfactant therapy and length of ventilatory support in the neonatal period. CONCLUSIONS ELBW children have more frequent respiratory tract complications, but fewer allergies at the age of 11 years compared with children born at term. Lower respiratory tract problems decrease in ELBW children with age. Respiratory tract infections are not connected with deficiency in humoral immunity.

Abstract
BACKGROUND Electrical bioimpedance analysis (BIA) is becoming more widely used in clinical practice as a method of body composition analysis. In healthy children blood pressure (BP) changes with age, body mass and height. Until now the relation between water compartments and BP in healthy children has not been evaluated. The aim of this study was to evaluate the relationship between body composition as well as water compartments (measured by electrical bioimpedance) and BP. METHODS The study was performed in 72 children (32 girls and 40 boys) aged: 6-7 and 12-13 years. BIA measurements were taken using Nutriguard Data Input device with Bianostic electrodes and following parameters were calculated: total body water (TBW), lean body mass (LBM), fat mass (FM), intra- and extracellular water (ICW, ECW) and phase angle alpha. BP was measured twice using the oscillometric method. RESULTS Elevated BP > 95th percentile for gender, age and height were observed in 9 children. A significant correlation between systolic (S)BP and TBW (R = 0.4023, p < 0.001), LBM (R = 0.3600, p = 0.002), FM (R = 0.4725, p < 0.001), ECW (R = 0.4598, p < 0.001) and body mass index (BMI) (R = 0.4089, p < 0.001) was found. Furthermore, diastolic (D)BP significantly correlated with TBW (R = 0.3056, p = 0.011), LBM (R = 0.2783, p = 0.021), FM (R = 0.3956, p < 0.001), ECW (R = 0.3869, p = 0.001) and BMI (R = 0.3550, p = 0.002). In the studied group malnutrition (weight < 3rd percentile) was found in 8 children and 2 had obesity (BMI > 95th percentile). Growth disorders were found in 6 children (5 of them being undernourished). CONCLUSIONS In the studied children SBP and DBP correlated with water compartments, lean body and fat masses derived from BIA. The problem of unrecognized hypertension and malnutrition in children and adolescents is still underestimated in the Polish population.

Abstract
AIM To determine the incidence of hyperglycaemia in very low birth weight preterm newborns. To assess risk factors in hyperglycemia and outcome in groups of children with and without clinically significant hyperglycaemia. MATERIAL AND METHODS The prospective study included newborns with very low birth weight in whom the continuous glucose monitoring system was used for glucose measurements. A standardized hyperglycaemia treatment schedule was implemented and a uniform nutrition strategy introduced. The patients were divided into groups: group A--patients with under 5% of the readings over 150 mg/dL of glucose (control group), group B--patients with more than 5% of the readings over 150 mg/dL of glucose and under 5% of the readings over 180 mg/dL of glucose (mild hyperglycaemia), and group C--patients with over 5% of the readings > 180 mg/dL or on insulin treatment (moderate or severe hyperglycaemia). RESULTS 63 patients were included in the study. Their mean gestational age was 27.7 weeks (SD:2.4), the mean birth weight was 1059g (SD: 262 g). Hyperglycaemia was detected in 27 (42.9%), including mild hyperglycaemia in 19 (30.2%), and moderate or severe hyperglycaemia in 8 (12.7%) neonates. Lower gestational age (p = 0.02) and higher CRIB IIscore (p < 0.01) were positively associated with hyperglycaemia. Early-onset sepsis (p < 0.01) was associated with higher glucose levels as well. A significantly higher mortality rate on the 28th day of life (p = 0.02), depending on the severity of hyperglycemia, was noted. No adverse effects related to the continuous glucose monitoring system were observed. CONCLUSIONS The study confirmed the usefulness and safety of the continuous glucose monitoring system in VLBW neonates. A continuous glucose monitoring system should be used in neonatal intensive care units as a standard method.

Abstract
AIM Evaluation of bioelectrical impedance values and body composition during early infancy in groups of preterm newborns and full-term newborns. MATERIAL AND METHODS A total of 38 newborns was enrolled in the study: 26 very low birth weight preterm newborns with the mean birth weight of 1236 g (SD: 161) as the study group and 12 term newborns with birth weight of 2500-4000 g as the control group. Anthropometric measurements and body composition using bioimpedance analysis at the age of 1 week and at the age of 3 months were assessed. RESULTS At the age of 1 week we noted higher resistance with the impedance variables R5, R50 R100 in the group of preterm newborns compared to the full-term newborns' group (923(144) vs. 647(78) p < 0.01; 870 (140) vs. 615 (73) p < 0.01; 844 (141) vs. 599 (72) p < 0.01). Moreover, the bioimpedance index and fat mass (%) were significantly lower in the group of preterm infants at the age of 3 months (3.81 (0.9) vs. 5.72 (1.1) p < 0.01; 16.1% (1.7) vs. 18.9% (2.7) p = 0.006). We observed a decreased amount of the percentage of total body water (TBW%) in both of the analyzed infant groups throughout the observational period. At the age of 3 months the amount of TBW % was similar in both groups (71.5% (7.03) vs. 70.8% (8.8) p = 0.8). CONCLUSIONS Bioimpedance analysis is a simple, non-invasive, repeatable method to estimate total body water, fat-free mass, and fat mass, both in term and preterm newborns. The study confirms differences in body composition between preterm newborns and full-term newborns. Moreover, we have shown that the differences are present until the end of the 3rd month of life, with the exception of the amount of water percentage (TBW %), which are similar in both groups.

Abstract
Prematurity is a high risk factor threatening the well-being of newborns and their somatic and psychological development in the future. Preterm babies need special medical care in which proper nutrition and metabolic control play an evident role. Our review presents the current knowledge concerning the clinical value of different methods investigated in the neonatal unit setting, including: protein markers of nutritional status (albumin,prealbumin, transferrin, and Retinol Binding Protein (RBP) and hormonal markers of nutritional status (somatomedin C, visfatin and ghrelin). Moreover, there is a discussion of the methods used for evaluating body composition. A variety of different techniques based on the physical properties of organisms was tested on neonates, e.g. the Dual Energy X-ray Absorptiometry (DEXA) method and Bioelectrical Impedance Analysis (BIA). Based on the review of the literature, we can speculate that none of the above methods represents a good single marker of the babies' nutritional status, or a prognostic factor for the future development of premature infants and infants born with IUGR. A combination of several methods from different groups seems to be a promising possibility. It is critical to continue looking for markers that will in a simple and efficient way help to optimize the correct nutritional therapy in infants with IUGR and those who were born prematurely.

Abstract
UNLABELLED In children with chronic kidney disease (CKD) anemia and calcium-phosphate disturbances are already present at early stages of the disease and require a comprehensive treatment. The aim of this study was to evaluate the efficacy of the treatment of biochemical disturbances, depending on the severity of CKD in children. MATERIAL AND METHODS The study included 71 children (44 boys, 27 girls) with CKD stage 1-5. Mean age was 11 ± 5 years, mean height: 135.7 ± 28 cm and mean eGFR 32 ml/min/1.73 m2. The serum hemoglobin, urea, creatinine, cystatin C, calcium, phosphorus and parathyroid hormone (PTH) levels were measured. eGFR was calculated according to Schwartz and Filler formulas, employing creatinine and cystatin C as markers. Patients were divided into groups depending on the stage of CKD [group 1: CKD stage 1+2 (GFR > 60), group 2: CKD stage 3 (GFR = 30-59) Group 3: CKD stage 4 (GFR = 15-29 ml/min/1.73 m2), group 4 - dialyzed children]. RESULTS The concentration of he- moglobin depending on the stage of CKD (group 1 vs. group 2 vs. group 3 vs group 4) was 12.95 vs. 12.68 vs. 12.47 vs. 11.3 g/dI, respectively. The concentration of total and ionized calcium was significantly lower in children on dialysis compared to patients treated conservatively. With the progression of CKD the concentration of phosphorus (1.39 vs. 1.4 vs. 1.49 vs. 1.82 mmolI) and PTH (21.7 vs 48.6 vs 99.9 vs. 219 pg/ml) significantly increased. Treatment with erythropoietin was used in 48% of children, calcium carbonate in 55% and alphacalcidol in 56% of patients. CONCLUSIONS Despite the use of regular treatment, with the progression of CKD a progression of anemia, increased serum phosphate and parathyroid hormone and a decrease in calcium levels in studied children was observed. The severity of metabolic disorders in dialyzed children indicates the need for administration of new and more effective drugs, to prevent early enough complications of CKD in the form of mineral bone disease and cardiovascular complications.

Abstract
INTRODUCTION Preterm newborns are at a particular risk of acute kidney injury (AKI) and sepsis. PURPOSE Assessment of urinary interleukin 18 (ulL-18) and urinary interleukin 6 (ulL-6) concentrations in association with AKI and sepsis respectively in newborns hospitalized in Neonatal Intensive Care Unit (NICU). MATERIAL AND METHODS An evaluation was carried out of the dependence of ulL-18 on neonatal birth weight (BW) and AKI as well as ulL6 on sepsis. In prospective study, the evaluation included 58 children with BW up to 2000 g. Clinical observations spanned the period between the 1st and 28th day of life. RESULTS The mean gestational age was 30.3 Hbd, mean BW was 1361.9 g. AKI was diagnosed in 35 (60.3%), sepsis in 22 (39.7%) neonates. For median values of uIL-18 and ulL-18/mgCr, as well as for mean logarithmically transformed values of ulL-18 and ulL-18/mgCr, negative, statistically significant linear correlations were demonstrated for BW. In population, median value of ulL-18 and ulL-18/mgCr decreased respectively by 8.21 pg/ml and 84.8 pg/mgCr per each 100 g increment of BW. A negative, statistically significant linear correlation with an average strength was noted for the dependency of the duration of AKI and BW. No significant differences were observed in uIL-18 and ulL-181 mgCr values between the investigated days of AKI and reference group. There was noted a significant increase of the values of uIL-6 and uIL-6/ mgCr on day 0 of sepsis confirmed by the ROC analysis with AUROC 78% and 74%, respectively. CONCLUSIONS ulL-18 and ulL-18/mgCr values might be a reliable marker of renal tubules maturation in newborns; ulL-18 is not a reliable marker in diagnosing AKI in neonatal population; ulL-6 and uIL-6/ mgCr concentration values measured on actual days may be regarded an early marker of sepsis; AKI duration in preterm neonates is negatively correlated with BW.

Abstract
To expand the knowledge about the consecutive expression of genes involved in the immune system development in preterm neonates and to verify if the environment changes the gene expression after birth we conducted a prospective study that included three cohorts: (A) extremely (gestational age (GA): 23-26 weeks; n = 41), (B) very (GA: 27-29 weeks; n = 39), and (C) moderately preterm infants (GA: 30-32 weeks; n = 33). Blood samples were drawn from the study participants on the 5th and 28th day of life (DOL). The mRNA samples were evaluated for gene expression with the use of GeneChip Human Gene 1.0ST microarrays. Differential expression analysis revealed small subsets of genes that presented positive or negative monotone trends in both the 5th (138 genes) and 28th DOL (308 genes) in the three subgroups of patients. Based on pathway enrichment analysis, we found that most of the pathways that revealed a positive monotone trend were involved in host immunity. The most significantly GA dependent pathways were T-cell receptor signaling pathway and intestinal immune network for IgA production. Overall 4431 genes were differentially expressed between the 5th and 28th DOL. Despite differences in gestational age, patients with the same postconceptional age have a very similar expression of genes.

Abstract
BACKGROUND The use of oxygen in acute treatment of asphyxiated term newborns is associated with increased mortality. It is unclear how hyperoxic reoxygenation after hypoxia affects transcriptional changes in the newborn lung. METHODS On postnatal day 7, C57BL/6 mice (n = 62) were randomized to 120-min hypoxia (fraction of inspired oxygen (FiO2) 0.08) or normoxia. The hypoxia group was further randomized to reoxygenation for 30 min with FiO2 0.21, 0.40, 0.60, or 1.00, and the normoxia group to FiO2 0.21 or 1.00. Transcriptome profiling was performed on homogenized lung tissue using the Affymetrix 750k expression array, and validation was carried out by real-time polymerase chain reaction and enzyme-linked immunosorbent assay. RESULTS The hypoxia-reoxygenation model induced hypoxia-inducible factor 1 (HIF-1) targets like Vegfc, Adm, and Aqp1. In total, ~70% of the significantly differentially expressed genes were detected in the two high hyperoxic groups (FiO2 0.60 and 1.00). Reoxygenation with 100% oxygen after hypoxia uniquely upregulated Gadd45g, Dusp1, Peg3, and Tgm2. Pathway analysis identified mammalian target of rapamycin (mTOR) signaling pathway, DNA repair, c-jun N-terminal kinase (JNK)-pathway regulation, and cell cycle after hyperoxic reoxygenation was applied. CONCLUSION Acute hypoxia induces HIF-1 targets independent of the reoxygenation regime applied. Hyperoxic reoxygenation affects pathways regulating cell growth and survival. DNA-damage-responsive genes are restricted to reoxygenation with 100% oxygen.

Abstract
BACKGROUND Retinopathy of prematurity (ROP) is one of the most common preventable causes of blindness and impaired vision among children in developed countries. The aim of the study was to compare whole-genome expression in the first month of life in groups of infants with and without ROP. METHODS Blood samples were drawn from 111 newborns with a mean gestational age of 27.8 wk on the 5th, 14th, and 28th day of life (DOL). The mRNA samples were evaluated for gene expression with the use of human whole-genome microarrays. The infants were divided into two groups: no ROP (n = 61) and ROP (n = 50). RESULTS Overall, 794 genes were differentially expressed on the 5th DOL, 1,077 on the 14th DOL, and 3,223 on the 28th DOL. In each of the three time points during the first month of life, more genes were underexpressed than overexpressed in the ROP group. Fold change (FC), which was used in analysis of gene expression data, ranged between 1.0 and 1.5 in the majority of genes differentially expressed. CONCLUSION Pathway enrichment analysis revealed that genes in four pathways related to inflammatory response were consistently downregulated due to the following variables: ROP and gestational age.

Abstract
AIM To study the impact that using antenatal steroid to treat threatened preterm delivery has on whole-genome expression. METHODS A prospective whole-genome expression study was carried out on 50 newborn infants, delivered before 32 weeks gestation, who had been exposed to antenatal steroids, including 40 who had received a full antenatal steroid course. Seventy infants not exposed to antenatal steroids formed the control group. Microarray analyses were performed five and 28 days after delivery, and the results were validated by real-time PCR. The study was conducted between September 2008 and November 2010. RESULTS Twenty thousand six hundred and ninety-three genes were studied in the infants' leucocytes. Thirteen were differentially expressed 5 days after delivery, but there were no differences at day 28. Four genes related to cancer or inflammation were up-regulated. Nine genes were down-regulated: six were Y-linked and associated with malignancies, graft-versus-host disease, male infertility and cell differentiation and three were associated with pre-eclampsia, oxidative stress and chloride/bicarbonate exchange. Seven gene pathways were up-regulated at day five and only one at day 28. These were associated with cell growth, cell cycle regulation, metabolism and apoptosis. CONCLUSION Antenatal steroid therapy affects a limited number of genes and gene pathways in leucocytes in preterm babies at day five of life. The effect is short-lived, but long-term effects cannot be ruled out.

Abstract
BACKGROUND Children who were <1000 g (ELBW extremely low birth weight) at birth more frequently present with wheezing which is the most common reason that pediatric consultation is sought. Therefore asthma is diagnosed very often. However is the asthma that is diagnosed in ELBW subjects atopic in origin, or is there a different etiology? AIM To determine if ELBW infants are at higher risk for the development of allergic and respiratory symptoms and to establish if there were any specific risk factors for these symptoms. METHODS 81 children born with a mean birthweight of 845 g (91% of available cohort) were evaluated at the mean age 6.7 years. The control group included 40 full-term children. The children were examined for clinical signs of allergy, and were subjected to the following tests: serum total IgE, skin prick tests (SPT), exhaled nitric oxide measurement (FeNO) and spirometry. RESULTS ELBW children had wheezing episodes more often (64% vs. 25%; OR (odds ratio): 5.38; 95% CI (confidence interval): 2.14-13.8) and were diagnosed more frequently with asthma (32% vs. 7.5%; OR: 5.83, 95% CI: 1.52-26) than their term born peers. The most important risk factors for wheezing persistence were hospitalization and wheezing episodes in first 24 months of life. Mean serum tIgE level (geometric mean: 32+/-4 vs. 56+/-4 kU/L; p=0.002) was higher and the number of children with positive results of tIgE level (12% vs. 32%; p=0.02) were more frequent in the control group. Children from the control group also more frequently had SPT, however this data was not statistically significant (11% vs. 24%; p=0.09). All of the ELBW had normal FeNO level (<=20 ppb), but 5 children from the control group had abnormal results (p=0.02). There was no difference between the groups in the occurrence of allergic symptoms. CONCLUSION ELBW children have more frequent respiratory, but not allergic problems at the age of 6-7 years compared to children born at term. The need for rehospitalization in the first 2 years of life, was a more important risk factor of future respiratory problems at the age of 7 than perinatal factors, the diagnosis of bronchopulmonary dysplasia or allergy.

Abstract
The incidence of acute kidney injury (AKI) at neonatal intensive care units (NICU) is estimated as 6-24%. Traditional AKI markers i.e. serum creatinine (SCr) concentration, fractional sodium exertion, urine sodium concentration and renal failure index--are low sensitivity and low specificity markers but beside remain very late ones. Serum creatinine concentration arises 48 hours after renal tissue damage. The paper presents contemporary knowledge concerning concentration reference ranges of some early AKI biomarkers (NGAL, hKIM1, OPN, IL18)--either in term or preterm newborns. The most current reports about chosen AKI biomarkers in newborns with uncomplicated clinical course and in children with AKI within the course of sepsis or after cardiopulmonary bypass surgery--were discussed. Disposing of the reliable clinical data referring to early AKI biomarkers constitutes a valuable aid for clinicians who having got to know about the actual risk possess the time for proper clinical interventions.

Abstract
BACKGROUND Infants born with extremely low birth weight < or =1000 g (ELBW) are endangered by many complications. AIM To assess whether infants born prematurely with ELBW are pre. disposed to arterial hypertension (HT) in a 7-year follow up examination. MATERIAL AND METHODS A group of 57 children (38 girls, 19 boys) at the age of 6.6+/-0.4 years was analyzed. Mean gestational age was 27.4+/-2 Hbd. All infants were born with ELBW (the mean weight was 861+/-127 g). The con. trol group consisted of 36 children (19 girls and 15 boys; the mean age was 7+/-0.9 years) born on time, with the mean birth weight 3559 g. The Ambu. latory Blood Pressure Measurement (ABPM) was performed in both groups. Mean arterial pressure (MAP), the night blood pressure (BP) decrease, BP. load, heart rate (HR) and presence of HT were analyzed. RESULTS Children born prematurely were significantly shorter than children from the control group (116 vs 125 cm; p<0.0001). HT diagnosis based both on MAP (15% vs 0%; p<0.02) and on BP loads (51% vs 22%; p<0.006), was significantly more common in the group of preterm infants. Moreo. ver, systolic BP-load (28% vs 17%; p<0.01), diastolic BP-load (27% vs 18%; p<0.01), daytime HR (99 vs 94/ min; p=0.01), nighttime HR (86 vs 791 min; p<0.001) and daily HR (93 vs 87/ min; p<0.001) were also significantly higher in the preterm group. Difference in night BP drops in both groups did not reach statistical significance. In the group of former preterms there was no correlation between birth weight or intrauterine growth and BP value. BP values: systolic (105 vs 100 mm Hg; p<0.02), diastolic (66 vs 63 mm Hg; p<0.01) and MAP (80 vs 76 mm Hg; p<0.01) were significantly higher in girls than in boys born prematurely with ELBW. CONCLUSION Infants born with ELBW are latterly predisposed to HT. Hypertension is more frequent in prematurely born girls. It is important to control BP in this group of children because early diagnose helps to decrease the risk of multiple organ complications caused by HT.

Abstract
BACKGROUND The long-term impact of prematurity on cardiac structure and function has not yet been fully discovered. OBJECTIVES To assess long-term cardiac complications in the regional cohort of extremely low birth weight (ELBW) children born in 2002-2004. MATERIAL AND METHODS Eighty-one children born as ELBW infants (91% of the available cohort) with a median birth weight of 890 g (25-75th percentile: 760-950) were evaluated at the mean age of 6.7 years. The control group included 40 children born full-term, selected from one general practice in the district. Echocardiography and 24-hour ambulatory blood pressure measurements (ABPM) were performed. The primary outcome variable was the presence of cardiac complications such as left ventricular hypertrophy (LVH), diastolic dysfunction or systolic dysfunction. RESULTS LVH was diagnosed in 4/81 ELBW children and 2/40 control children (p = 1.0). Concentric remodeling was detected in 8 (10%) subjects from the ELBW group and in 2 (5%) from the control group (p = 0.49). There were no patients with diastolic or systolic dysfunction in either group. After having expressed the results of M-mode echocardiography as z-scores for body surface area (BSA), statistically significant differences were observed for right-ventricle dimension in diastole (-1.49 ± 1.25 vs. -0.31 ± 0.91; p < 0.001), LV inner dimension in diastole (-0.53 ± 1.26 vs. 0.13 ± 0.94; p = 0.01) and left atrium (-0.93 ± 1.07 vs. -0.15 ± 1.02; p < 0.01). Heart rate (HR) was significantly faster in ELBW children (92.9 ± 8.4 vs. 86.7 ± 7.4 bpm; p = 0.01 adjusted for BSA) and they also had significantly higher night-time blood pressure [mean (z-score): 1.15 vs. 0.2; p = 0.02] without nocturnal dipping (night-time dipping <10%: 13 (16.7%) vs. 2 (5.2%), p = 0.13). CONCLUSIONS No differences were found between the groups in the occurrence of cardiac complications. Ex-preterm ELBW children at age 6 may have a faster HR, smaller cardiac dimensions on echocardiography and higher nocturnal blood pressure. The clinical relevance of these findings is unknown.

Abstract
INTRODUCTION A better understanding of the developmental problems in extremely low birth weight (ELBW) preterm infants may enhance their chances of proper adaptation to their environment and make it possible to retrospectively assess perinatal and neonatal methods of treatment. The aim of the study was to evaluate the cognitive and motor development of ELBW children born from 2002 to 2004 in the 7th year of life. Based on these results and perinatal mortality data, it was established what chance the children have to live free of severe complications. MATERIAL AND METHODS Two hundred and four alive newborns with birth weight .1000 g were born in the Malopolska voivodship between 1.09.2002 and 31.08.2004. One hundred and fifteen children (56%) died in early infancy. The study included 81 (91%) children out of the 89 surviving ones. Their mean gestational age at birth was 27.3 weeks. (SD: 2.1 weeks) and their mean birth weight was 840g (SD: 130g). Neurosensory disturbances were assessed in all the children and their cognitive development was evaluated with the use of the WISC-R (Wechsler Intelligence Scale for Children . Revised) scale. The children were divided into 3 groups: group I . normal development (full motor capacity and IQ >84 points and no vision or hearing impairment), group II . mild or moderate impairment (cerebral palsy level I, II or III according to the Gross Motor Function Classification System [GMCS], or IQ 40-84 points, or abnormal vision or hearing, or signs of the hyperactivity syndrome), group III . severe impairment (cerebral palsy level IV, and/or IQ <40 points, or deafness/blindness). RESULTS Forty-five (56%) children were included in group I, 25 (30%) in group II and 11 (14%) in group III. Moreover, other neurologic abnormalities, such as uneven development, problems with concentration, or abnormal grapho-motor ability were highly prevalent in the group of ELBW children. The incidence of cerebral palsy in the population studied was 16%, the incidence of deafness and severe hearing impairment was 11%, and blindness and severe vision impairment . 12%. In general, the chance of survival free of severe complications was merely 15% in children with birthweight .700 g, 28% in children with birth weight 701- 800 g, 45% in children with birth weight 801-900 g, and 62% in children with birth weight 901-1000 g. CONCLUSIONS 1. The data gathered in a regional study may yield valuable information useful in assessing the prognosis of the general health status of ELBW newborns. 2. Most of the children present uneven development, problems with concentration, or abnormal grapho-motor ability, which may be a cause of learning problems and abnormal relationships with peers. 3. A follow-up study up to adulthood is required for this group of ELBW newborns.

Abstract
UNLABELLED Children born with extremely low birth weight often present delayed growth in the first years of their lives: they remain shorter and weigh less than their peers. Current reports published worldwide state that later in life these children are at an increased risk of cardiac and vascular diseases, diabetes and obesity. Abnormal distribution and the excess of fat tissue predispose them to develop the metabolic syndrome. THE AIM of the study was to evaluate the somatic development of seven-year-old children born with birth-weight ≤1000 g (ELBW) in the Malopolska voivodship and to estimate the content and distribution of fat tissue. Moreover, the risk factors of disturbed somatic development were evaluated. MATERIALS AND METHODS Two hundred and four live newborns with birth weight ≤1000 g were born in the Malopolska voivodship between 1.09.2002 and 31.08.2004. One hundred and fifteen of these children (56%) died in early infancy. The study included 81 children in the 7th year of life out of the 89 surviving ones. Their mean gestational age at birth was 27.3 weeks. (SD: 2.1 weeks) and their mean birth-weight was 840 g (SD: 130 g). All the children underwent anthropometric measurements and the thickness of the skin fold over the triceps was measured. Body mass index (BMI) was calculated and the body composition was assessed by multifrequency bioimpedance. The control group consisted of 39 children born at term chosen randomly from the general population and matched with regard to age and sex. RESULTS The ELBW children in the 7th year of life were shorter (z-score: -1.06±1.4 p<0.001), had lower body mass (z-score: -0.57±0.9; p=0.01), smaller head circumference (z-score: -1.2±1.3; p<0.001), lower BMI (z-score: -0.99±1.6; p<0.001) as compared to their peers. Fat tissue mass was lower in the ELBW group than in the control group (11% vs 16%; p<0.01). The most retarded somatic development was observed in the group of children suffering from cerebral palsy. CONCLUSIONS 1. Children born with ELBW, at 7 years of life, present significantly retarded somatic development as compared with their full-term peers. 2. The most important risk factor of somatic development disturbances is cerebral palsy. 3. Children born with low birth weight and ELBW, need long term follow up.

Abstract
Chronic respiratory diseases are a common complication of preterm birth, particularly among very immature infants or those suffering from bronchopulmonary dysplasia. Major progress in the treatment of preterm newborns has changed the pattern of late respiratory complications. The major respiratory problem in infancy and early childhood is respiratory exacerbations caused by infections (particularly viral ones), which need hospitalization. The symptoms become mild in school-age children; however, a group of children still present with chronic airway obstruction defined by recurrent episodes of wheezing and decreased lung function tests (decreased forced expiratory volume). For some preterm infants, particularly those with bronchopulmonary dysplasia, obstructive lung disease persists into adulthood. They are very likely to develop chronic obstructive pulmonary disease or similar disease later in life. In these patients, a program of lung function monitoring and pulmonary prophylaxis by means of elimination of specific risk factors in adulthood is advisable.

Abstract
Administration of drugs off-label occurs commonly in pediatrics. The majority of pediatricians prescribe unregistered drugs deliberately. The most common reasons that prompt them to do so are the necessity to treat their patients while there is no alternative medication, and their conviction that the treatment with an unregistered drug is more efficient and/or safer than the treatment with a registered one. The pediatric practice departs from the registered use of drugs most commonly in the following points: the dose, indications, different age of a patient. It is an alarming fact that a substantial group of medications used to treat children has not been included into clinical trials which might result in their registration as drugs suitable for use in pediatrics. Current legal regulations, which have been introduced mainly with the view of protecting patients' safety, considerably inhibit the implementation of clinical trials with children. Moreover, parents, guardians, as well as health-care providers often perceive medical experiments in a very negative way, which causes further difficulties. It should be stressed that the administration of drugs off-label is each pediatrician's autonomous decision for which they take full responsibility.

Abstract
INTRODUCTION The universal hearing screening program has special value for neonatal intensive care unit (NICU) patients because of the multiple risk factors of hearing loss they are subjected to. AIM To summarize the results of hearing tests on consecutive stages of the screening program and to evaluate the value of hearing loss factors. MATERIALS AND METHODS The group included 851 infants born between 1.10.2006 - 31.12.2009 and treated in the NICU of the University Children's Hospital in Cracow, Poland. Infants with abnormal screening test results (TEOAE) and/or with hearing loss risk factors, or absent from the first stage of the test were qualified for the next stage hearing diagnostics (TEOAE+ABR). Multivariate logistic regression was used in order to evaluate hearing loss risk factors. RESULTS 679 (80%) newborns were screened by the first stage hearing test. 579 (68%) were tested on the second level diagnostics. 60 patients are still under control. 11/519 (2.1%) had hearing impairment (sensorineual or mixed). 10 had bilateral and 1 had unilateral hearing impairment. The family history was negative for congenital hypoacusis. 1st minute Apgar score < 4 points, congenital TORCH infections and craniofacial anomalies were independent risk factors of hearing loss, however it was not possible to predict more than 2/11 patients with hearing loss based on these factors. Patients with abnormal result of the first stage test had lower birth weight and gestation age than that with normal result. The sensitivity of the first TEOAE test was 82%, specificity 70%, PPV 6.2%, NPV 99%. CONCLUSION Hearing impairment was rarely a complication of treatment in the NICU, although it was 10 times more frequent in comparison to the whole newborn population. Because the sensitivity, specificity and PPV of first hearing test is not satisfactory, next stage diagnostics in the audiology department are strongly recommended.

Abstract
Progress achieved in the development of medical care for children born prematurely has resulted in increased survival of the smallest and most immature infants. At the same time increased incidence of the late complications of prematurity such as bronchopulmonary dysplasia (BPD) and retinopathy of prematurity (ROP) has become a growing problem. The aim of the study was to identify groups of genes potentially involved in the development of long-term complications of prematurity, by conducting genome wide microarray expression analysis. The prospective cohort study was conducted, 52 premature babies were included. At the 5th, 14th and 28th day of life samples of the peripheral blood were taken from the study participants. Subsequently, total RNA was extracted and microarray experiment, with the use of GeneChip Human Gene 1.0 ST Array (Affymetrix), was performed. The analysis of the results was carried out in the separate cohorts of prematures. Within 52 infants 2 groups were distinguished--children without BPD (n = 25) and children with BPD (n = 27). Significant difference in the expression of 251 genes was observed. Additionally, a group of 20 participants of the study, in whom ROP was diagnosed, was compared with the group of the remaining 32 children without proven retinopathy. The analysis revealed a significant difference in the expression between the analyzed groups with regard to 752 genes. Further study is needed to verify the obtained results. The impact of the over- and underexpressed genes should be studied, as well as detailed analysis of the metabolic pathways should be performed.

Abstract
We assessed the long-term renal complications in a regional cohort of extremely low birth weight (ELBW) children born in 2002-2004. The study group, comprising 78 children born as ELBW infants (88% of the available cohort), was evaluated with measurement of serum cystatin C, urinary albumin excretion, renal ultrasound, and 24-h ambulatory blood pressure measurements. The control group included 38 children born full-term selected from one general practice in the district. Study patients were evaluated at a mean age of 6.7 years, and had a median birthweight of 890 g (25th-75th percentile: 760-950 g) and a median gestational age of 27 weeks (25th-75th percentile: 26-29 weeks). Mean serum cystatin C levels were significantly higher (0.64 vs. 0.59 mg/l; p = 0.01) in the ELBW group. Hypertension was diagnosed in 8/78 ELBW and 2/38 of the control children (p = 0.5). Microalbuminuria (>20 mg/g of creatinine) was detected only in five ELBW children (p = 0.17). The mean renal volume was significantly lower in the ELBW group (absolute kidney volume 81 ml vs. 113 ml; p < 0.001, relative kidney volume 85 vs. 97%; p < 0.001). Abnormally small kidneys (<2/3 of predicted size) were detected in 19 ELBW and four control children (p = 0.08). Multivariate logistic regression revealed that the only independent risk factor for renal complications was weight gained during neonatal hospitalization (odds ratio: 0.67; 95% confidence interval: 0.39-0.94). Serum cystatin C and kidney volume are significantly lower in school-age ELBW children. It is important to include systematic renal evaluation in the follow-up programs of ELBW infants.

Abstract
BACKGROUND The study aim was to compare somatic development, body composition, insulin growth factor-1 (IGF-1) serum concentration and serum lipid profile between small-for-gestational-age (SGA) and appropriate-for-gestational-age (AGA) 7-year-old extremely low birth weight (ELBW) children and full-term (FT) controls. MATERIALS AND METHODS Fifty-seven AGA ELBW children [mean birth weight (BW) 850 g and mean gestational age (GA) 26.4 weeks] and 24 SGA ELBW children (mean BW 833 g, mean GA 29.5 weeks) were evaluated. The control group included 37 age- and sex-matched FT children from one outpatient center. RESULTS Nine AGA and four SGA were found to have short stature defined as height < 3rd percentile for chronological age (p = 0.9). In the AGA cohort, the results of weight, head circumference, triceps skin fold and body mass index (BMI) measurements were significantly reduced in the short-stature subgroup. IGF-1 serum concentrations differed significantly between short-stature and normal-stature subgroups (121 vs. 193 ng/mL; p = 0.02). In the SGA cohort, weight and serum concentrations of total cholesterol (5.03 vs. 4.26 mmol/L; p = 0.04), LDL cholesterol (3.24 vs. 2.38 mmol/L; p = 0.01) and IGF-1 (113 vs. 211 ng/mL; p = 0.01) differed significantly between the short-stature and normal-stature subgroups. CONCLUSIONS Short stature at the age of 7 years was diagnosed in a similar percentage of AGA and SGA former ELBW infants. In both cohorts short-stature children have significantly lower weight and serum IGF-1 levels. IGF-1 seems to be involved in prolonged growth restriction among ELBW infants, regardless of whether they were AGA or SGA.

Abstract
Obesity is a well-known risk factor for arterial hypertension. The aim of this study was to analyze which surrogate marker of adiposity, i.e., body mass index (BMI) or fat mass (FM), as measured by bioimpedance analysis (BIA), best correlated with blood pressure in healthy children. Body weight, height, and casual blood pressure (BP) were measured in 193 healthy children (103 boys), aged 8-16 years. Body composition was determined by BIA. The correlation between BMI and age was linear, whereas the correlation between percentage of FM and age was nonlinear and it was different in boys and girls. Blood pressure standard deviation scores (SDS) correlated with FM SDS (BIA) over the entire normal range (systolic: r = 0.26, p = 0.002; diastolic: r = 0.33, p < 0.01). An evaluation of the children based on BP (three groups: BP < 50th percentile, 50th < BP > 95th percentile; BP > 95th percentile) revealed that hypertensive children had a higher BMI (17.6 vs. 19.4 vs. 26.2 kg/m(2), respectively) and a greater FM (14.0 vs. 16.8 vs. 30.2%, respectively). In conclusion, the divergence in FM in healthy boys and girls can be determined by BIA but not by BMI. In healthy children, BP within the entire normal range correlated with FM, children with established hypertension presented with a significantly higher FM. The study points to FM as an important determinant of BP pressure in obese and non-obese children.
