BOYRAZ, M., PIRGON, O., AKYOL, B., DUNDAR, B., CEKMEZ, F., and EREN, N.
- Abstract
AIM: The aim of the present study was to analyze the relationship between epicardial adipose tissue thickness (EATT) and echocardiographic parameters, such as carotid intima-media thickness (cIMT), myocardial performance index (MPI), left ventricular (LV) systolic and diastolic function, and LV mass index in adolescents with obesity. PATIENTS AND METHODS: One hundred and thirty eight obese adolescents and 63 lean subjects were enrolled in the study. The body mass index standard deviation scores (BMI-SDS) between 1.65-2.49 and 2.50-2.99 were considered as mild-moderate and severe obesity, respectively. All of the subjects underwent transthoracic echocardiographic examination for determination of LV function, LV structure, LV mass index, and MPI. Epicardial adipose tissue thickness and cIMT were also measured during echocardiography. RESULTS: The EATT measurements were increased significantly in patients with severe obesity compared to lean subjects (7.38±1.76 vs 4.28±0.79 mm, respectively; p = 0.001), but there was no significant difference between the obesity groups. The average LV mass index measurements were higher in both mild-moderately and severely obese patients in comparison with the lean children (87.5±34.8, 88.5±23.0, and 62.4±18.2 g/m², respectively; p < 0.01), but there was no significant difference between the obesity groups. EATT was positively correlated with BMI-SDS, waist and hip circumference, blood pressure, fasting glucose, insulin, HOMA-IR, hs-CRP (high-sensitivity C-reactive protein), triglyceride levels, cIMT, LV mass index, and MPI in the severe obesity group. EATT was the only independent predictor of cIMT in the multivariate analysis (standardized β coefficient = 0.70, p < 0.001). CONCLUSIONS: The present study demonstrates a close relationship between EATT and cIMT, and LV functions and LV mass index in obese adolescents. Assessments of EATT and cIMT in particular during routine echocardiographic examinations might be used as a feasible and reliable method for the evaluation of obesity and its related cardiovascular risks during childhood.

- Abstract
AIM: The aim of this study was to assess adiponectin, visfatin, HOMA-IR, glucose and triglyceride levels in term, preterm and extremely low birth weight (ELBW) babies. Each of these three groups was subdivided into two groups as small-for-gestational age (SGA), and appropriate-for-gestational age (AGA). 30 term, 30 preterm and 30 extremely low birth weight infants were included into the study. RESULTS: There was no significant difference in term and preterm infants for serum adiponectin, visfatin, and HOMA-IR levels. There were also no significant differences between term and preterm infants for glucose and triglycerides. The serum visfatin, insulin and HOMA-IR levels (p = 0.001, p = 0.001 and p < 0.05, respectively) were higher in ELBW group than preterm group. Comparing the subgroups as SGA and AGA in all main groups, only in ELBW group there were no significant differences in serum adiponectin, visfatin, HOMA-IR and insulin levels. CONCLUSIONS: We suggest that visfatin can be used as an early indicator of insulin resistance. Independent of being SGA, ELBW itself may be a risk factor for insulin resistance. In the follow-up of these babies the risk of obesity, metabolic syndrome and cardiovascular diseases may be increased as in SGA babies. [ABSTRACT FROM AUTHOR]

CEKMEZ, F., TANJU, I. A., CANPOLAT, F. E., AYDINOZ, S., AYDEMIR, G., KARADEMIR, F., and SARICI, S. U.
- Abstract
BACKGROUND: Mean platelet volume [MPV] is an important predictor for many diseases and larger platelets are more reactive and associated with shortened bleeding time. Although elevated MPV values are related to respiratory distress syndrome [RDS] in neonates, there are, to our knowledge, no data investigating the relationship between MPV and other diseases of preterm infants. AIM: To assess the correlation between MPV and the occurrence of various morbidities of prematurity such as necrotizing enterocolitis [NEC], bronchopulmonary dysplasia [BPD], sepsis, retinopathy of prematurity [ROP], and intraventricular hemorrhage [IVH] in a cohort of very preterm infants. SUBJECTS: We studied infants with a gestational age of < 34 weeks and a birth weight of < 1500 g admitted to a third level Neonatal Intensive Care Unit. Enrolled infants were divided into NEC and non-NEC, sepsis and non-sepsis, ROP and non-ROP, BPD and non-BPD and IVH and non-IVH groups. MPV was evaluated at birth [cord blood] and repeated at 48-72 hours of life. RESULTS: Two hundred and seventy two infants were studied. MPV measured at birth was similar between sepsis and non-sepsis, and ROP and non-ROP groups. MPV values were higher in infants with BPD [9.08±1.3 fl], IVH [8.4±1.1fl] and NEC [8.6±0.7 f] when compared to the control group [7.6±0.6 fl] in the first day of life. CONCLUSIONS: High MPV in the first hours of life may reflect the presence of a risk factor for the development of NEC, BPD and IVH in extremely preterm infants. This might be associated with inflammatory and oxidative process. However, our data indicate that higher MPV values are not associated with the development of sepsis or ROP in this study population.

- Abstract
Congenital longitudinal deficiency of the fibula (CLDF) is the most common congenital defect involving the long bones. There have been many different classifications developed for fibula deficiency. Achterman and Kalamchi's classification is most commonly used and will be described. Our case was complied with type II. Other anomalies includes cardiac anomalies, thrombocytopenia absent-radius (TAR) syndrome, thoracoabdominal schisis, spina bifida and renal anomalies, but most associated anomalies are skeletal. We here presented firstly in literature an infant with congenital fibula deficiency accompanying with deafness. [ABSTRACT FROM AUTHOR]

- Abstract
Background: Many factors contribute to the development of BPD basically by increasing inflammation in preterm lungs. However, premature neonates have insufficient anti-inflammatory capacity. We aimed to evaluate the effect of etanercept, an anti-TNF agent, on BPD development in newborn rat model with hyperoxia-induced lung injury., Methods: Thirty-two newborn rats were divided into 3 groups as control group (Group 1, n = 11), hyperoxia + placebo group (Group 2, n = 10), and hyperoxia + etanercept group (Group 3, n = 11). Histopathological and biochemical analysis were performed in order to assess inflammation and oxidative stress. Superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) activities, and malondialdehyde (MDA) levels were studied, histopathological scoring and radial alveolar count were applied in lung tissue. Lamellar body membrane protein, vascular endothelial growth factor (VEGF), nuclear factor-kappaB (NF-κB) gene expressions were studied in immunohistochemical evaluation of tissue samples. All three groups were compared with each other in terms of all parameters., Results: SOD and GSH-Px activities were significantly higher, whereas MDA levels were lower in group 3, compared to group 2 (p < 0.001). Histopathological scores were lower, lamellar body membrane protein expression and radial alveolar count were higher in group 3 (p < 0.05). NF-κB expression was higher in group 2, but lower in group 3 in comparison with group 1. Expression of VEGF was decreased in group 2 but came close to group 1 with etanercept treatment in group 3., Conclusions: We found etanercept treatment to be protective in newborn rats with hyperoxia-induced lung damage.

- Abstract
Background: Neonatal sepsis is an important cause of neonatal morbidity and mortality in the neonatal intensive care unit. Soluble triggering receptor expressed on myeloid cells-1 (sTREM-1) has been evaluated in sepsis and septic shock, and it was found to be valuable in distinguishing septic cases from nonseptic cases. Endocan is constitutively expressed by endothelial cells, and high levels of endocan may be of relevance for the promotion of systemic inflammation. The aim of this study was to investigate whether the levels of sTREM-1 and endocan were increased in late-onset neonatal sepsis., Methods: Patients were classified into septic and nonseptic groups. Blood was collected from a peripheral vein of all septic newborns and healthy newborns at the time of initial laboratory evaluation before any treatment, and within 48-72 hours after initiation of treatment. Serum sTREM-1 and endocan measurements were performed when the study was finished., Results: The study population comprised of 50 neonates: 20 nonseptic neonates and 30 septic neonates. The groups were similar with regards to baseline characteristics. The initial measurements of interleukin-6 (IL-6), sTREM-1, endocan, and immature/total neutrophil ratio (I/T ratio) were significantly higher in septic neonates in comparison with nonseptic neonates. Receiver operating characteristic (ROC) curve analyses revealed that IL-6, sTREM-1, endocan, and I/T ratio resulted in significant areas under the curve (AUC) with respect to early identification of septic neonates. Soluble TREM-1 and IL-6 performed best to distinguish septic neonates from nonseptic neonates. Univariate logistic regression analysis showed that increased IL-6 and sTREM-1 were strong predictors of neonatal late-onset sepsis., Conclusion: Serum sTREM-1, IL-6, endocan levels, and I/T ratio increased in septic neonates. However, the diagnostic accuracy of circulating sTREM-1 seemed to be better than endocan and I/T ratio, but lower than IL-6., (Copyright © 2015. Published by Elsevier B.V.)

- Abstract
Background: Cytomegalovirus (CMV) infections are the leading cause of infectious hearing loss and central nervous system disease among children worldwide. In this study, we aimed to determine the birth prevalence of congenital CMV infection in live-born infants in Turkey., Methods: In total, 944 consecutive live-born infants born from 926 pregnant women were included in this study. CMV-DNA was investigated in saliva samples of all newborns within the first 3 days after birth using TaqMan-based real-time PCR., Results: The birth prevalence of congenital CMV infection in live-born infants was 1.91% (18/944), and all congenitally infected infants were asymptomatic at birth. The prevalence of congenital CMV infection was 16.7% (3/18) in twin pregnancies and 1.32% (12/908) in single pregnancies (p = 0.002). Genotyping analysis showed glycoprotein B-1 (gB1) to be the most frequently detected genotype at 83.3%., Conclusion: The study results suggest that the majority of congenital CMV infection in Turkey occurs following nonprimary maternal infection. We believe that congenital CMV infection and its long-term effects have been underestimated in our country, as infected infants are usually asymptomatic at birth.

- Abstract
Objective: Histone acetylation and deacetylation may play a role in the pathogenesis of inflammatory lung diseases. We evaluated the preventive effect of valproic acid (VPA), a histone deacetylase (HDAC) inhibitor, on neonatal hyperoxic lung injury., Methods: Forty newborn rat pups were randomized in normoxia, normoxia+VPA, hyperoxia and hyperoxia+VPA groups. Pups in the normoxia and normoxia+VPA groups were kept in room air and received daily saline and VPA (30 mg/kg) injections, respectively, while those in hyperoxia and hyperoxia+VPA groups were exposed to 95% O2 and received daily saline and VPA (30 mg/kg) injections for 10 days, respectively. Growth, histopathological, biochemical and molecular biological indicators of lung injury, apoptosis, inflammation, fibrosis and histone acetylation were evaluated., Results: VPA treatment during hyperoxia significantly improved weight gain, histopathologic grade, radial alveolar count and lamellar body membrane protein expression, while it decreased number of TUNEL(+) cells and active Caspase-3 expression. Expressions of TGFβ3 and phospho-SMAD2 proteins and levels of tissue proinflammatory cytokines as well as lipid peroxidation biomarkers were reduced, while anti-oxidative enzyme activities were enhanced by VPA treatment. VPA administration also reduced HDAC activity while increasing acetylated H3 and H4 protein expressions., Conclusions: The present study shows for the first time that VPA treatment ameliorates lung damage in a neonatal rat model of hyperoxic lung injury. The preventive effect of VPA involves HDAC inhibition.

- Abstract
Objective: Neonatal sepsis remains a major cause of morbidity and mortality in newborns. The chemokine CXCL12 and its receptor CXCR4 are now known to play an important role in inflammatory states. However, it is unclear how chemokines respond to late-onset neonatal sepsis., Methods: Patients were classified into the groups of septic and non-septic ones. Samples of venous blood were obtained from all septic and non-septic newborns at the beginning and within 48-72 h after initiation of treatment. Serum levels of CXCR4 and CXCL12 were measured., Results: Concentrations of IL-6, CXCR4 and CXCL12 at the time of diagnosis were significantly higher in the septic neonates compared with the non-septic ones. Additionally, there were statistically significant differences in septic neonates between the first and the second levels of IL-6, CXCR4, CXCL12 and I/T ratio. ROC curve analyses revealed that IL-6, CXCR4, CXCL12 and I/T ratio resulted in significant AUC with respect to early identification of septic neonates. Univariate logistic regression analysis showed that increased IL-6, CXCR4 and CXCL12 were strong predictors of neonatal LOS., Conclusions: Serum CXCR4 and CXCL12 levels increase in septic neonates and that both chemokines decrease within 48-72 h of treatment. Serum concentrations of both chemokines represent promising novel biomarkers for neonatal sepsis.

- Abstract
Despite major advances in intensive care, sepsis continues to be a major cause of morbidity and mortality. Vitamin D is involved in various physiologic functions, including cellular responses during infection and inflammation. The aim of this study was to evaluate diagnostic value of 25-hydroxyvitamin D in childhood sepsis because it can be fatal if diagnosis delayed. The study included 40 children with sepsis and 20 children without sepsis (control group). We included only the patients with high probable sepsis, judged by clinical and laboratory findings, including positive blood culture. Blood samples were collected from patients with sepsis before treatment (pre-treatment group) and 48-72 hours later (post-treatment group). Treatment varied from ampicillin-sulbactam to cephalosporin. Blood samples were collected from control group once on admission. Serum 25-hydroxyvitamin D levels were significantly higher in sepsis (pre-treatment group) than control group (74 ± 8 ng/ml vs. 28 ± 12 ng/ml, p = 0.01) and the serum 25-hydroxyvitamin D levels were decreased to 44 ± 5 ng/ml (p = 0.01) after treatment. Moreover, we found significant positive correlation between 25-hydroxyvitamin D and each of well-know sepsis markers, C-reactive protein, tumor necrosis factor-α and interleukin-6. A cut-off point of 20 ng/mL for serum 25-hydroxyvitamin D showed 84% sensitivity and 76% specificity for sepsis diagnosis. This is the first study evaluating the diagnostic role of vitamin D in pediatric sepsis, thereby suggesting that serum 25-hydroxyvitamin D level can be used as a diagnostic marker for sepsis with high sensitivity and specificity.

- Abstract
Context: Bronchopulmonary dysplasia (BPD) is a common outcome of premature birth. Currently, no effective preventive therapy is available for BPD, but the major role of O2 toxicity in the development of BPD has gained attention, particularly for developing new antioxidants for prevention. The major protective mechanism of melatonin (MT) includes free-radical scavenging activity and activation of the cyclooxygenase-prostoglandin enzyme system., Objective: The aim of this study was to evaluate the effects of MT on cytoprotection and healing in a model of hyperoxic lung injury in newborn rats., Methods: This is a case-control study design., Setting: The study occurred at the Gulhane Military Medical Academy in Ankara, Turkey., Intervention: A total of 60 newborn pups from dated, Sprague-Dawley, pregnant rats were divided equally into 3 groups as follows: (1) control group, (2) hyperoxia-exposed group, and (3) hyperoxia-exposed plus MT-treated group (MT group). Hyperoxia was performed by placing these pups in an oxygen chamber for 14 d during which oxygen was continuously delivered., Outcome Measures: At the end of the 14 d, lung specimens were collected and evaluation of the lamellar-body count and determination of histopathological scores were performed. Also, the activities of superoxide dysmutase (SOD), glutathione peroxidase (GSH-Px), and malondialdehyde (MDA) were assessed., Results: The histopathological scores of the MT group were significantly lower than those of the hyperoxia-exposed group. The mean lamellar-protein and radial-alveolar counts in the MT group were found to be significantly higher than those of the hyperoxia-exposed group. Also, SOD and GSH-Px levels were significantly higher and MDA levels were significantly lower in the MT group compared with the hyperoxia-exposed group., Conclusion: MT therapy was found to have a protective effect in a model for hyperoxic lung injury in neonatal rats. Therefore, the research team suggests that MT therapy may be used for prevention of BPD in preterm infants after confirmation of this data by future clinical studies.

Background: sE-selectin has recently been suggested as a surrogate marker for prediction of ROP development., Aims: The possible role of serial plasma sE-selectin measurements in early prediction and diagnosis of ROP was evaluated., Study Design: Prospective observational study, Subjects: Forty six preterm infants aged <34weeks of gestation and weighing <1500 g were enrolled. Of these, 26 constituted the ROP group and 20 constituted the no-ROP group. sE-selectin levels were measured serially in blood samples on the 1st day and on 14th and 28th postnatal days., Outcome Measures: The primary outcome measure was to evaluate the role of sE-selectin concentrations in prediction of ROP., Results: The mean gestational age and birth weight were significantly lower in the ROP group. The mean sE-selectin concentrations in ROP group were significantly greater than those in no-ROP group at each time point (1st, 14th and 28th days of postnatal life). A receiver operating characteristic (ROC) analysis showed that at a plasma concentration of ≥86ng/mL on the 1st postnatal day, sE-selectin had a sensitivity of 100% and a specificity of 94.1% with a positive predictive value of 96.3% and a negative predictive value of 100%. Plasma sE-selectin concentrations were significantly greater in infants who developed ROP in three different time points., Conclusions: This study shows for the first time that measurement of plasma sE-selectin concentrations as early as the first day of life might help identify preterm infants at risk of ROP., (Copyright © 2014 Elsevier Ltd.

- Abstract
Background: Bronchopulmonary dysplasia (BPD) remains an important complication of preterm births. The soluble form of ST2 (sST2), interleukin-33 (IL-33), and soluble form of the urokinase plasminogen activator receptor (suPAR) have attracted increasing attention as biomarkers for different diseases. The aim of the current study was to assess the predictive value of plasma sST2, IL-33, and suPAR levels in patients with risk of BPD development., Methods: A total of 38 babies were studied prospectively on delivery to the neonatal intensive care unit. Serum levels of IL-33, sST2, and suPAR were measured using enzyme-linked immunosorbent assay. Serum samples were collected from umbilical cord (at the time of delivery, termed CB) and peripheral blood (on day 14, termed PB)., Results: Levels of suPAR (PB-suPAR) and sST2 (PB-sST2) in the peripheral blood of the BPD group were significantly higher than the corresponding levels in the non-BPD group (P < 0.001, P = 0.028, respectively. There was a statistically significant correlation between PB-suPAR levels and the severity of BPD (P < 0.001)) when the suPAR results were analyzed using the receiver operating characteristic curve., Conclusion: PB-suPAR and PB-sST2 levels are sensitive and specific independent predictive biomarkers in preterm babies with BPD.

- Abstract
Background: Hepatitis B virus (HBV), hepatitis C Virus (HCV), and human immunodeficiency virus (HIV) infections are significant causes of morbidity and mortality all over the world, especially in underdeveloped countries like Afghanistan. Limited data are available concerning the seroprevalence of HBV, HCV and HIV in the pediatric age group in Afghanistan ., Objectives: The aim of the study was to assess HBV, HCV and HIV serology among children at an outpatient clinic in Kabul., Patients and Methods: A total number of 330 children were included to the study from outpatient clinics of Ataturk Kabul ISAF Role II Military Hospital from May to November 2012. Hepatitis B surface antigen (HBsAg), hepatitis C antibody (anti-HCV), and human immunodeficiency virus antibody (anti-HIV) were measured., Results: The mean age of children was 6.5 ± 4.2 years. The frequency of positive results for HBsAg, anti-HBs and anti-HCV in all age groups were 12 (3.6%), 47 (14.2%) and 2 (0.6%), respectively. Anti-HIV was not detected in any of the children's serum samples. The frequency of positive results for HBsAg was significantly higher in children older than six years than in other age groups., Conclusions: Vaccination program including HBV has begun during the last five years in Afghanistan. The continuation of the vaccination program is of great importance. Vaccination program and implementation steps should be revised and the deficiencies, if any, should be overcome without delay.

- Abstract
Preterm premature rupture of membranes (PPROM) is defined as rupture of membrane that happens before the onset of labor and 37 weeks. Subclinical intrauterine infection is major etiological factor in the pathogenesis that increases mortality and morbidity associated with PPROM. This study was performed to evaluate the levels of maternal serum urokinase plasminogen activator receptor (uPAR), ST2 and interleukin (IL)-33 in PPROM and its relation with maternofetal infectious and morbidity. A total of 74 pregnant women, of which 49 with PPROM between 24 and 34 weeks gestation, and 25 normal pregnant women without PPROM were included in the study. Study group was seperated into 2 subgroups as PPROM and PPROM-histological chorioamnionitis (PPROM-HC). The blood samples were taken before the any medication. The mean serum IL-33, ST2, and uPAR values in the PPROM-HC group were significantly higher than PPROM and control group. The cut-off values of IL-33, ST2, and uPAR were determined as 5.2, 2 and 6.4 ng/mL, respectively. A cut-off value of IL-33 of 5.2 ng/mL, the cut-off of ST2 of 2 ng/mL and the cut-off of uPAR of 6.4 ng/mL showed similar sensitivity, specificity to IL-6 and the better sensitivity and specificity as compared to C-reactive protein and total leucocyte count in predicting infection in PPROM. We evaluated the predictive value of uPAR, ST2 and IL-33 in PPROM and we concluded that all of them can be used as reliable biomarkers to determine infection without any clinical signs but it is necessary to be studied in different cohort groups and infectious diseases.

- Abstract
The aim was to report outcomes of retinopathy of prematurity (ROP) screening conducted between March 1999 and March 2012 in a retrospective manner before October 2005 (Group 1) and prospective manner thereafter (Group 2). Data of the neonates with either a gestational age of 34 weeks or less or with a birth weight of less than 1501 g were analyzed to elucidate the frequency of ROP, ROP-related risk factors and population characteristics. Of the 640 neonates, 240 (37.5%) had any stage of ROP. Gestational age ≤32 weeks, birth weight <1500 g, oxygen therapy, respiratory distress syndrome, and sepsis were found as independent determinants for any stage of ROP. Gestational age ≤28 weeks, mechanical ventilation, intraventricular hemorrhage, and outborn infant status were found as independent determinants for treatmentrequiring severe ROP (8.6%). Frequency of ROP did not seem to follow a decreasing trend; however, neonates in Group 2 were more immature and sicker. Therefore, check-backs seem to be necessary to follow the dynamic nature of ROP.

- Abstract
Background: Bronchopulmonary dysplasia (BPD) is an important cause of morbidity. The aim of this study was to evaluate the preventive effect of cytidine 5'-diphosphocholine (CDP-choline) treatment on hyperoxic lung injury in a neonatal rat model., Methods: A total of 30 newborn pups were divided into control, hyperoxia, and hyperoxia + CDP-choline groups. After birth, pups in the control group were kept in room air and received saline injections, whereas those in hyperoxia and hyperoxia + CDP-choline groups were exposed to 95% O₂ and received daily injections of saline and CDP-choline throughout postnatal day 10, respectively. Histopathological scoring, radial alveolar count, lamellar body membrane protein expression, fibrosis, proinflammatory cytokine levels, lung tissue and bronchoalveolar lavage (BAL) fluid phospholipid content, and apoptosis were evaluated., Results: Hyperoxia-induced severe lung damage was reduced significantly by CDP-choline treatment. Radial alveolar count and lamellar body membrane protein expression were significantly recovered, and the number of terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate nick-end labeling-positive cells, active caspase-3 expression, and tissue proinflammatory cytokine levels were decreased by CDP-choline administration. Lung tissue and BAL phospholipid contents showed significant increases after CDP-choline administration., Conclusion: These data show that CDP-choline ameliorates hyperoxic lung injury in a neonatal rat model. It may therefore be suggested that CDP-choline may be a novel therapeutic option for the prevention of BPD.

- Abstract
Background: Cytidine 5'-diphosphocholine (CDP-choline) is an endogenous intermediate in the biosynthesis of phosphatidylcholine, a contributor to the mucosal defense of the intestine. The aim of this study was to evaluate the possible cytoprotective effect of CDP-choline treatment on intestinal cell damage, membrane phospholipid content, inflammation, and apoptosis in a neonatal rat model of necrotizing enterocolitis (NEC)., Methods: We divided a total of 30 newborn pups into three groups: control, NEC, and NEC + CDP-choline. We induced NEC by enteral formula feeding, exposure to hypoxia-hyperoxia, and cold stress. We administered CDP-choline intraperitoneally at 300 mg/kg/d for 3 d starting from the first day of life. We evaluated apoptosis macroscopically and histopathologically in combination with proinflammatory cytokines in the gut samples. Moreover, we determined membrane phospholipid levels as well as activities of xanthine oxidase, superoxide dismutase, glutathione peroxidase, and myeloperoxidase enzymes and the malondialdehyde content of intestinal tissue., Results: Mean clinical sickness score, macroscopic gut assessment score, and intestinal injury score were significantly improved, whereas mean apoptosis score and caspase-3 levels were significantly reduced in pups in the NEC + CDP-choline group compared with the NEC group. Tissue proinflammatory cytokine (interleukin-1β, interleukin-6, and tumor necrosis factor-α) levels as well as tissue malondialdehyde content and myeloperoxidase activities were reduced, whereas glutathione peroxidase and superoxide dismutase activities were preserved in the NEC + CDP-choline group. In addition, NEC damage reduced intestinal tissue membrane phospholipids, whereas CDP-choline significantly enhanced total phospholipid and phosphatidylcholine levels. Long-term follow-up in additional experiments revealed increased body weight, decreased clinical sickness scores, and enhanced survival in CDP-choline-receiving versus saline-receiving pups with NEC lesions., Conclusions: Our study reports, for the first time, beneficial effects of CDP-choline treatment on intestinal injury in a neonatal rat model of NEC. Our data suggest that CDP-choline may be used as an effective therapeutic agent to prevent NEC., (Copyright © 2013 Elsevier Inc. All rights reserved.)

- Abstract
Aim: The aim of this study was to investigate the relationships between 25-hydroxy-vitamin D (25(OH)D) and insulin resistance in obese adolescents with non-alcoholic fatty liver disease (NAFLD)., Patients and Methods: Eighty-seven obese adolescents (45 girls and 42 boys, mean age: 12.7 ± 1.3 years, mean body mass index standard deviation score (BMI-SDS): 2.1 ± 0.3) and 30 lean subjects (15 girls and 15 boys, mean age: 12.3 ± 1.45 years, mean BMI-SDS: 0.5 ± 0.7) were enrolled for the study. The obese subjects were divided into two subgroups based on the presence or absence of fatty liver with high transaminases (NAFLD group and non-NAFLD group). Fasting blood samples were assayed for 25(OH)D, transaminases, glucose, and insulin levels. Insulin resistance was calculated by the homeostasis model assessment (HOMA-IR)., Results: 25(OH)D measurements were decreased in both obese groups (NAFLD and non-NAFLD) in comparison with the lean group (29.5 ± 18.4 vs. 41.0 ± 17.9 vs. 48.1 ± 22.2 ng/mL). However; the NAFLD group had significantly lower measurements of 25(OH)D than the non-NAFLD group (p < 0.001) and lean group (p < 0.001). 25(OH)D was negatively correlated with HOMA-IR (r = 0.158, p = 0.01) and with alanine aminotransferase (r = 0.794, p = 0.03) in the NAFLD obese group. There was no significant associations between fasting insulin, BMI-SDS and 25(OH)D in obese groups., Conclusion: We suggest that low 25(OH)D occurs commonly in obese adolescents with NAFLD and we demonstrated an association between insufficient vitamin D status and low insulin sensitivity in obese adolescents with NAFLD., (© Crown Copyright 2013 Published by Elsevier Ltd on behalf of Asia Oceania Assoc. for the Study of Obesity.

- Abstract
Background: Necrotizing enterocolitis (NEC) is one of the most common gastrointestinal emergencies in newborn infants but up to now there is no completely effective treatment for it., Objective: In order to show that a combination of melatonin and prostaglandins may be useful to save lives, we use newborn rat as a model of necrotizing enterocolitis to test the hypothesis of using the combination therapy might have more potential effect on mucosal cytoprotection and healing., Patients and Methods: A total of 60 newborn pups from 5 time-mated Sprague-Dawley pregnant rats were divided equally into 5 groups as follows: NEC (subjected to NEC), NEC+Melatonin, NEC+Prostaglandin, NEC+Prostaglandin+Melatonin and control. These animals were fed with hyperosmolar formula 3 times daily and subjected to 100% CO2 inhalation for 10 min, +4°C cold exposure for 5 min, and 97% O2 for 5 min twice daily to induce NEC. This procedure was applied to the pups for 3 days., Results: The macroscopic scoring, intestinal injury scoring and apoptosis index scoring were all found to be significantly lower in NEC+Prostaglandin+Melatonin group compared with NEC group. Anti-oxidant enzyme activities were significantly higher, whereas lipid peroxidation was significantly lower in NEC+Prostaglandin+Melatonin group compared with NEC group., Conclusion: This combination therapy showed cytoprotective and healing effects on mucosa in the intestinal tissue of rat pups in necrotizing enterocolitis model. Therefore, this therapy might also show benefit in preterm infants with NEC. After confirmation of this data by other clinical and experimental studies, it may be a novel therapeutic option for the prevention of NEC in preterm infants., (Copyright © 2013 Elsevier B.V.

A male infant was born to a 24-year-old mother (gravida 1 para 1) by cesarean delivery at 33 1/7 weeks of gestation. The physical examination revealed a large mass protruding from the baby's mouth, which appeared to be attached to the palate. Tracheostomy was performed immediately in the delivery room. A partial surgical excision was performed on the second postnatal day, removing most of the teratoma (epignathus), which was attached to the back of the pharynx and protruding from the baby's mouth measuring 13×11×9 cm and weighing 545 g. The final pathological diagnosis was "malignant epignathus with nephroblastoma component." According to our knowledge, this is the first case that have malignant epignathus including nephroblastoma component in the literature., (Copyright © 2013 Elsevier Inc. All rights reserved.)

- Abstract
Infants born prematurely are prone to bronchopulmonary dysplasia which is a devastating form of chronic lung disease that develops in very low birth weight infants. Toll-like receptors (TLRs) are pattern recognition receptors that initiate innate immune responses. We tested TLR2, 4, and 9 levels in the lungs of rat pups given caffeine at the first days of postnatal life. Twenty-four rat pups equally divided into three groups. The study group received caffeine immediately after birth for ten days. The levels of TLR9 were found significantly higher in study group than control groups. We conclude that the beneficial and anti-inflammatory effects of caffeine in the lungs of newborn rats may be due to increased TLR9 levels., (Copyright © 2013 Elsevier B.V. All rights reserved.)

- Abstract
Background: Oxygen-induced lung injury is believed to lead to the development of bronchopulmonary dysplasia in premature infants. We have evaluated the beneficial effects of Nigella sativa oil (NSO) on rats with hyperoxia-induced lung injury., Methods: Thirty newborn Sprague-Dawley rats were randomly divided into 3 groups as hyperoxia (95% O(2)), hyperoxia+NSO and control (21% O(2)). Pups in the hyperoxia+NSO group were administered intraperitoneal NSO at a dose of 4ml/kg daily during the study period. Histopathologic, immunochemical, and biochemical evaluations (superoxide dismutase [SOD], glutathione peroxidase [GSH-Px], malonaldehyde [MDA] and myeloperoxidase [MPO]) were performed., Results: In the histopathologic and immunochemical evaluation, severity of lung damage was significantly lower in the hyperoxia+NOS group (P<.05). Tissue GSH-Px and SOD levels were significantly preserved, and MDA, MPO levels were significantly lower in the hyperoxia+NSO group (P<.05)., Conclusion: NSO significantly reduced the severity of lung damage due to hyperoxia., (Copyright © 2011 SEPAR.

- Abstract
Aim: We hypothesized that circulating apelin concentrations in preterm babies might be linked with retinopathy of prematurity (ROP), similar to IGF-1 levels., Patients & Methods: A total of 97 infants born with a gestational age before 32 weeks in 2007-2009 were screened for ROP at the Gata Haydarpasa Hospital (Turkey). Fourteen of them with classified ROP stage 3-5 comprised our study group., Results: The non-ROP group had higher apelin and IGF-1 levels than ROP neonates at birth. After 4-6 weeks, postnatal ROP subjects had lower apelin and IGF-1 levels than non-ROP controls. At the end of the study, the change in apelin levels was positively correlated with the change in IGF-1 levels (r = 0.852; p = 0.01)., Conclusion: We suggested that the pathogenesis of ROP, which is regarded as a neovascular retinal disorder, includes variations in the levels of apelin and IGF-1.

- Abstract
Listeria monocytogenes is a very important life-threatening bacteria in certain risk groups such as neonates, pregnant women, elderly people, transplant recipients and others with impaired cell-mediated immunity. However, its infections are very rare in healthy children. Reports of listeriosis in newborn period are limited. We report a case of neonatal listeriosis with erythematous rash, intractable convulsions, severe early neonatal sepsis, disseminated intravascular coagulation, multiple organ dysfunction syndrome and death. Although an empirical antibiotic therapy including ampicillin (semisentetic penicillin) and aminoglycoside combination is effective by the means of a probable Listeria infection, the progression of the very early-onset disease may be fatal, despite vigorous treatment efforts as in our case.

HOMA-IR, fasting insulin, visfatin and parathormone (PTH) levels were significantly higher in LGA with diabetic mother group than AGA and LGA with non-diabetic mother group., Conclusion: Based on the findings of this study, visfatin, adiponectin and 25(OH)D levels can be used as specific markers for insulin sensitivity and may help advance new therapies for glucose intolerance spectrum., (Copyright © 2012 Elsevier Ltd.

- Abstract
Purpose: The authors hypothesized that circulating visfatin concentrations in preterm infants might be linked with retinopathy of prematurity (ROP)-like insulin-like growth factor I (IGF-I) levels., Methods: The study group comprised 88 children born with a gestational age younger than 32 weeks between 2007 and 2009 who were screened and/or treated for ROP. The authors collected fetal cord blood (sample 1) and a blood sample at 4 to 6 weeks postnatal age (sample 2) for laboratory investigations., Results: The non-ROP group had higher visfatin-1, visfatin-2, insulin-1, insulin-2, (IGF-I)-1, and (IGF-I)-2 levels than the ROP group (P < .001 for all levels). Change in visfatin was positively correlated with change in IGF-I and change in insulin (P < .001 and P < .001, respectively). Change in IGF-I was positively correlated with change in insulin (P < .001)., Conclusion: Similar to IGF-I levels, determination of visfatin levels can be a predictive marker of ROP, but more studies are needed., (Copyright 2012, SLACK Incorporated.)

- Abstract
Background: Necrotizing entrocolitis (NEC) remains a potentially fatal disease in premature infants despite the recent advances in neonatal care. It is a disease with a multifactorial etiology leading to the one common final pathway of necrosis and inflammmation of the neonatal intestine., Methods: Calprotectin is a calcium and zinc-binding protein in human neutrophils. Its concentration rises in various organic bowel diseases in adults and is resistant to degradation and has been proposed as a useful, simple, and rapid diagnostic method of inflammatory bowel disease that shows gastrointestinal inflammation in children and adults., Results: We found that infants with necrotizing enterocolitis had increased fecal calprotectin concentrations, and there was a correlation between calprotectin concentrations and severity of NEC., Conclusions: We concluded that fecal calprotectin is a useful marker for diagnosis and severity of NEC in preterm infants.

- Abstract
Objective: To investigate the relation of circulating four adipokines (apelin, vaspin, visfatin, adiponectin) with markers of insulin sensitivity in large for gestational age (LGA) infants., Patients and Methods: Forty LGA infants (20 LGA born from diabetic mothers and 20 LGA born from non-diabetic mothers) and 34 appropriate for gestational age (AGA) infants were recruited. Hyperinsulinism and insulin resistance was evaluated using the homeostasis model assessment (HOMA-IR), fasting glucose-to-insulin ratio (FGIR), quantitative insulin-sensitivity check index (QUICK-I) from fasting samples. Plasma adiponectin and vaspin levels were determined by radioimmunoassay. Determination of visfatin and apelin levels was performed by enzyme immunoassay., Results: HOMA-IR, apelin and visfatin levels (p<0.001, p<0.001, p<0.001, respectively) were significantly elevated and adiponectin levels, FGIR and QUICK-I values. (p<0.001, p<0.001, p<0.05, respectively) were significantly lower in the LGA group. Vaspin levels were higher in the LGA group than AGA neonates without a significance. The LGA infants with diabetic mother had significantly higher visfatin, apelin, HOMA-IR values, fasting insulin levels and significantly lower adiponectin, FGIR, QUICK-I values. Apelin and visfatin were correlated positively, and adiponectin was correlated negatively with birthweight, HOMA-IR values and fasting insulin levels., Conclusion: Based on the findings of this study, it is too difficult to explain relation between birthweight and these adipocytokines, but findings of high insulin, HOMA-IR, visfatin, apelin and low adiponectin levels in the LGA neonates showed that these adipocytokines can be used as a good predictor for metabolic syndrome., (Copyright © 2011 Elsevier Ltd.
