Neonatal Resuscitation Practices in Turkey: A Survey of the Turkish Neonatal Society and the Union of European Neonatal and Perinatal Societies.

OBJECTIVE: Optimal care in the delivery room is important to decrease neonatal morbidity and mortality. We aimed to evaluate neonatal resuscitation practices in Turkish centers. MATERIALS AND METHODS: A cross-sectional survey consisted of a 91-item questionnaire focused on delivery room practices in neonatal resuscitation and was sent to 50 Turkish centers. Hospitals with <2500 and those with ≥2500 births/year were compared. RESULTS: In 2018, approximately 240 000 births occurred at participating hospitals with a median of 2630 births/year. Participating hospitals were able to provide nasal continuous-positiveairway-pressure/high-flow nasal cannula, mechanical ventilation, high-frequency oscillatory ventilation, inhaled nitric oxide, and therapeutic hypothermia similarly. Antenatal counseling was routinely performed on parents at 56% of all centers. A resuscitation team was present at 72% of deliveries. Umbilical cord management for both term and preterm infants was similar between centers. The rate of delayed cord clamping was approximately 60% in term and late preterm infants. Thermal management for preterm infants (<32 weeks) was similar. Hospitals had appropriate equipment with similar rates of interventions and management, except conti nuous-positive-airway-pressure and positive-end-expiratory-pressure levels (cmH2O) used in preterm infants (P = .021, and P = .032). Ethical and educational aspects were also similar. CONCLUSIONS: This survey provided information on neonatal resuscitation practices in a sample of hospitals from all regions of Turkey and allowed us to see weaknesses in some fields. Although adherence to the guidelines was high among centers, further implementations are required in the areas of antenatal counseling, cord management, and circulation assessment in the delivery room.

Intravenous Immunoglobulin Use in Hemolytic Disease Due to ABO Incompatibility to Prevent Exchange Transfusion.

Introduction: Intravenous immunoglobulin (IVIG) has been widely used to treat the hemolytic disease of the newborn (HDN). Although it has been shown that IVIG treatment reduces the duration of phototherapy and hospitalization, the use of IVIG in hemolytic disease due to ABO incompatibility has been controversial in recent years. This study aimed to investigate the role of IVIG in the prevention of exchange transfusion in infants with ABO HDN who presented with bilirubin levels at or above the level of exchange transfusion. Materials and Methods: This study evaluated the data of infants with ABO HDN in the Turkish Neonatal Jaundice Online Registry. The infants with ABO HDN who met the total serum bilirubin level inclusion criteria (within 2-3 mg/dL of exchange transfusion or even above exchange transfusion level) were included in the study according to the guidelines from the American Academy of Pediatrics and the Turkish Neonatal Society. All patients were managed according to the unit protocols recommended by these guidelines and received light-emitting diode (LED) phototherapy. Infants who only received LED phototherapy, and who received one dose of IVIG with LED phototherapy were compared. Results: During the study period, 531 term infants were included in the study according to inclusion criteria. There were 408 cases in the phototherapy-only group, and 123 cases in the IVIG group. The demographic findings and the mean bilirubin and reticulocyte levels at admission were similar between the groups (p > 0.05), whereas the mean hemoglobin level was slightly lower in the IVIG group (p = 0.037). The mean age at admission was earlier, the need for exchange transfusion was higher, and the duration of phototherapy was longer in the IVIG group (p < 0.001, p = 0.001, and p < 0.001, respectively). The rate of re-hospitalization and acute bilirubin encephalopathy (ABE) was higher in the IVIG group (p < 0.001 and p = 0.01, respectively). Conclusion: In this study, we determined that one dose of IVIG did not prevent an exchange transfusion nor decrease the duration of phototherapy in infants, who had bilirubin levels near or at exchange transfusion level, with hemolytic disease due to ABO incompatibility.

Clinical characteristics and neonatal outcomes of liveborn newborns with hydrops fetalis treated in a tertiary level neonatal intensive care unit.

BACKGROUND: This study was performed for examining the neonatal results and aetiological factors of neonates with hydrops fetalis (HF) and determining the factors affecting mortality. METHODS: The medical records of liveborn neonates with HF who were admitted to a tertiary Neonatal Intensive Care Unit (NICU) in Konya, Turkey, between 2013 and 2019 were reviewed retrospectively. The demographic data, prenatal intervention, clinical findings, and results of the patients were recorded. RESULTS: A total of 32.6% of the 46 liveborn HF infants had immune HF (IHF), while 67.4% had nonimmune HF (NIHF); there was prenatal diagnoses in 39 (84.7%) cases. Cordocentesis and blood transfusion (n = 14; 30.4%) were the prenatal diagnosis and treatment interventions with the highest rate. A total of 16 patients (34.7%) received in utero interventional treatment. It was determined that the mean gestational age was not associated with mortality; moreover, birthweight (BW), Apgar score and the need for mechanical ventilation affected mortality. CONCLUSION: The prognosis changes according to different etiologies of HF. However, despite the developments in neonatal care, mortality is still high in HF infants.

Is there any relation between connective tissue growth factor and scar tissue in vesicoureteral reflux?

Gültekin ND, Benzer M, Tekin-Neijmann S. Is there any relation between connective tissue growth factor and scar tissue in vesicoureteral reflux. Turk J Pediatr 2019; 61: 71-78. Vesicoureteral reflux (VUR) is the most common uropathy in childhood which leads to increased frequency of urinary tract infection (UTI) and renal scarring. Connective tissue growth factor (CTGF) plays an important role in the development of glomerular and tubulointerstitial fibrosis in progressive kidney diseases. The aim of this study was to investigate the relation between urinary CTGF and renal damage resulted from VUR. This cross sectional study included 70 patients with VUR and 62 healthy sex and age matched children. Urinary creatinine and CTGF (uCTGF) concentrations were analysed in all cases and CTGF to creatinine ratio were calculated. The records of radiologic evaluations of the patients including ultrasound, voiding cystouretrography and 99m-technetium dimercaptosuccinic acid (DMSA) scintigraphy were obtained retrospectively. The patient group was further divided into two groups according to the existence of renal cortical scarring in the DMSA scan. The study consisted of three groups; Group 1 (control group) 62 children, Group 2 (VUR positive, scar negative) 24 patient, Group 3 (VUR positive, scar positive) 46 patient (VUR+scar). The medians of uCTGF and uCTGF to creatinine ratio of the three groups were significantly different (p < 0.001). Pairwise group comparisons revealed that Group 1 had significantly lower uCTGF level and uCTGF/creatinine ratio, as compared to Groups 2 and 3 (p < 0.001 and p=0.002, respectively). There was no statistically significant difference between Groups 2 and 3 (p=0.052). uCTGF is significantly increased in children with VUR, independent on the presence of renal scarring. Increased uCTGF, even in the absence of the renal scarring, could be interpreted as development and a progression of glomerular and tubulointerstitial fibrosis in vesicoureteral reflux. Further experimental and clinical investigations are required to fully elucidate the mechanism of CTGF in vesicoureteral reflux.

Glanzmann Thrombasthenia in a Newborn with Heterozygous Factor V Leiden and Heterozygous MTHFR C677T Gene Mutations.

INTRODUCTION: Glanzmann thrombasthenia is a rare congenital platelet dysfunction. CASE CHARACTERISTICS: A 2-day-old male neonate delivered at 35 weeks' gestation was referred with extensive bruising and jaundice. His elder sibling had Glanzmann thrombasthenia, and his mother had thrombophilic risk factors. Flow cytometric analysis revealed absent CD41/CD61. A molecular thrombophilia panel revealed the presence of heterozygous factor V Leiden G1691A and methylenetetrahydrofolate reductase C677T gene mutations. OUTCOME: General precautions to avoid injuries and spontaneous bleeding were advised. MESSAGE: Life-threatening bleeding may not be the first finding in cases of thrombasthenia accompanied by thrombophilic risk factors.

The Turkish Neonatal Jaundice Online Registry: A national root cause analysis.

BACKGROUND: Neonatal jaundice (NNJ) is common, but few root cause analyses based on national quality registries have been performed. An online registry was established to estimate the incidence of NNJ in Turkey and to facilitate a root cause analysis of NNJ and its complications. METHODS: A multicenter prospective study was conducted on otherwise healthy newborns born at ≥35 weeks of gestation and hospitalized for only NNJ in 50 collaborator neonatal intensive care units across Turkey over a 1-year period. Patients were analyzed for their demographic and clinical characteristics, treatment options, and complications. RESULTS: Of the 5,620 patients enrolled, 361 (6.4%) had a bilirubin level ≥25 mg/dL on admission and 13 (0.23%) developed acute bilirubin encephalopathy. The leading cause of hospital admission was hemolytic jaundice, followed by dehydration related to a lack of proper feeding. Although all infants received phototherapy, 302 infants (5.4%) received intravenous immunoglobulin in addition to phototherapy and 132 (2.3%) required exchange transfusion. The infants who received exchange transfusion were more likely to experience hemolytic causes (60.6% vs. 28.1%) and a longer duration of phototherapy (58.5 ± 31.7 vs. 29.4 ± 18.8 h) compared to infants who were not transfused (p < 0.001). The incidence of short-term complications among discharged patients during follow-up was 8.5%; rehospitalization was the most frequent (58%), followed by jaundice for more than 2 weeks (39%), neurological abnormality (0.35%), and hearing loss (0.2%). CONCLUSIONS: Severe NNJ and bilirubin encephalopathy are still problems in Turkey. Means of identifying at-risk newborns before discharge during routine postnatal care, such as bilirubin monitoring, blood group analysis, and lactation consultations, would reduce the frequency of short- and long-term complications of severe NNJ.

Urinary L-FABP as a marker of vesicoureteral reflux in children: could it also have a protective effect on the kidney?

PURPOSE: Liver-type fatty acid-binding protein is a small cytoplasmic protein which is expressed in the human renal proximal tubular epithelium and synthesized in response to renal tubular injury. The aim of the present study was to investigate the importance of urinary liver-type fatty acid-binding protein levels in children who diagnosed with vesicoureteral reflux. METHODS: Fifty-six patients with vesicoureteral reflux and 51 healthy controls were enrolled to the study. The cases were divided into three groups as follows: group A-the controls, group B-the patients who had renal parenchymal scarring and group C-the patients who had no scarring. Urinary liver-type fatty acid-binding protein was measured by enzyme-linked immunosorbent assay method. Creatinine was measured by modified Jaffe method, protein was measured by turbidimetric method, and urine density was determined by using the "falling drop" procedure. RESULTS: Urinary liver-type fatty acid-binding protein and urinary liver-type fatty acid-binding protein/creatinine levels were significantly higher in the whole patient group than in the controls (p = 0.016, 0.006). Significant differences were also determined by comparing the three groups (p = 0.015, 0.014), and those levels were found as significantly higher in group C. CONCLUSION: Urinary liver-type fatty acid-binding protein was considered to be helpful for the diagnosis of vesicoureteral reflux, and also it might contribute to understand the mechanisms causing scar tissue formation especially for the patients who had vesicoureteral reflux. Further clinical and experimental investigations are required to elucidate in detail the physiology of liver-type fatty acid-binding protein.
