RESUMEN
BACKGROUND: To compare the amplitude-integrated electroencephalography (aEEG) monitoring (short-term versus prolonged-period) for neonatal seizure detection and outcome. METHODS: The aEEG monitoring in a historical cohort (n = 88, preterm:42, and term:46) with neonatal encephalopathy between 2010-2022 was re-evaluated for neonatal seizures (electrographic, electro-clinical, and clinical seizures) and EEG background scoring. The cohort was dichotomized: group I (short-period with 6-12 h, n = 36) and group II (prolonged-period with 24-48 h, n = 52). Both monitoring types were evaluated for the diagnostic accuracy of the "patients with seizures" and for outcome characteristics (early death as well as adverse outcomes at 12 months of age). RESULTS: A total of 67 (76 %) neonates of the cohort were diagnosed as "patients with seizures": electrographic-only seizures in 10 (15 %), electro-clinical seizures in 22 (33 %), and clinical-only seizures in 35 (52 %). The aEEG provides the "patients with seizures" in neonates with a 36.5 % rate with both types of monitoring: 17/36 (47.2 %) with short-term and 15/52 (28.8 %) with prolonged-period monitoring. The prolonged period aEEG had higher diagnostic values for seizure detection (sensitivity = 0.73 and negative predictivity value = 0.81). However, the aEEG background scores were similar for both types of aEEG monitoring, respectively (the mean ± SD: 4.73 ± 2.9 versus 4.4 ± 4. p = 0.837). The aEEG scoring was correlated with the magnitude of brain injury documented with MRI, the early death, and the adverse outcome at 12 months of age. CONCLUSIONS: Both aEEG types are valuable for monitoring the "patients with seizures" and outcome characteristics.

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.
RESUMEN
BACKGROUND: Vitamin D and its receptor (VDR) effects on the gastrointestinal system are among its most critical multisystemic effects. METHODS: This study aimed to reveal that VDR gene polymorphisms may constitute a risk factor for necrotizing enterocolitis (NEC). VDR Fok1-Bsm1-Apa single-nucleotide polymorphisms were analyzed in the NEC group (n = 74) and the control group (n = 147). Among 1112 babies at and below 36 weeks of gestational age who were hospitalized between January 2013 and December 2016 with a diagnosis of prematurity, 74 of a total of 148 patients who developed NEC during follow-up (NEC group) were included in the study. When NEC was diagnosed according to clinical and radiological findings and staged using Modified Bell criteria, 9 (12.1%) of 74 babies were stage 1A, 13 (17.5%) stage 1B, and 5 (6.7%) stage 2A, 33 (44.5%) stage 2B, 7 (9.4%) stage 3A, 7 (9.4%) stage 3B. Of 964 babies who did not develop NEC during follow-up, 147 were included as the control group in the study. Genotyping of VDR polymorphisms was assayed by real-time PCR. From 221 premature babies in the NEC and control groups, 2 ml peripheral blood was taken appropriately and meticulously into an EDTA tube. DNA was isolated from these blood samples. DNA amplification was performed using a thermal cycler (Applied Biosystems GeneAmp PCR System 9600). RESULTS: When the two groups were compared in terms of the prevalence of VDR Fok1 C/T genotype, it was found that TT genotype increased the risk of NEC by 2.697 times, and there was a significant relationship between TT genotype and the risk of NEC (p = 0.041). Multivariable logistic regression analysis was performed in terms of gestational age, birth weight, VDR gene polymorphism data between NEC and the control group. According to the analysis results, TT polymorphism, increased the risk of disease 4.5 times (p = 0.033). CONCLUSION: Fok 1 C > T polymorphism in the VDR gene plays a role in the development of NEC. Identifying the risk groups by detecting gene polymorphisms that cause increased susceptibility to NEC may assist in the follow-up of these patients and in making early treatment decisions for them. IMPACT: In this study examining the non-bone effects of the genetic differences in vitamin D metabolism in premature babies, Fok 1 polymorphism has been observed to be an essential risk factor for NEC. This is the first study in our country that has investigated the relationship between VDR gene polymorphism and necrotizing enterocolitis among the Turkish population. Identifying the risk groups by detecting gene polymorphisms that cause increased susceptibility to NEC may assist in the monitoring of these patients and in making early treatment decisions for them.

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.
RESUMEN
Background: Respiratory distress syndrome (RDS) is the most common respiratory disease in premature infants. Exogenous natural surfactant preparations are used in the treatment of RDS. In recent years, it has become increasingly evident that surfactant plays an immunoregulatory role. Objectives: The aim of this study was to evaluate cytokine and chemokine response following three different regimens of natural surfactant treatment in preterm newborns with RDS. Methods: Premature newborns below 32 weeks of gestation who were intubated for RDS and given early surfactant rescue therapy were included in the study. Newborns were randomly divided into three groups and Beractant 100 mg/kg (B-100), Poractant alfa 100 mg/kg (Pα-100) and Poractant alfa 200 mg/kg (Pα-200) were administered intratracheally. Blood samples and transtracheal aspirates (TA) were collected just before and 4-6 h after the surfactant treatment. Total eosinophil count, inducible T Cell alpha chemoattractant (ITaC), macrophage inflammatory protein 3 beta (MIP3b), interleukins (IL) 5, 8, 9, 10, 13, immunoglobulin E (IgE), interferon gamma (IFN-γ), eotaxin and tumor necrosis factor beta-1 (TGF-ß1) were measured from blood and tracheal aspirate samples. Results: A total of 45 infants, 15 in each group, were included in the study. Mean gestational age, birth weight, antenatal, demographic and clinical characteristics of the study groups were similar. IFNγ concentration and eosinophil counts in TA decreased after surfactant replacement in all groups, especially in the infants treated with Pα-100 and Pα-200. Eotaxin, TGF beta and IL-8 concentrations in TA increased significantly in the infants treated with Pα-100 and Pα-200. IL-9 levels in TA decreased in the B-100 group but increased in the Pα-100 and Pα-200 groups. Blood levels of cytokines and chemokines showed significantly decreased levels of ITaC and MIP3b only in the B-100 group, but no significant change was observed in the Pα-100 and Pα-200 groups. Conclusion: In our study, the different immunomodulatory effects of natural surfactant preparations on newborn lung is proven. We found that Poractant α, one of the natural surfactant preparations, shifted the lung immune system toward TH2.
RESUMEN
PURPOSE: To assess the impact of clinical neonatal seizures on outcome characteristics of preterm and term newborns with neonatal encephalopathy (NE). METHODS: We designed a prospective comparative study with 53 babies (preterm neonates: 26 and term neonates: 27) with NE: group 1 (preterm neonates with seizures, n = 13), group 2 (preterm neonates without seizures, n = 13), group 3 (term neonates with seizures, n = 13) and group 4 (term neonates without seizures, n = 14). The functional outcome characteristics of the survivors were assessed by the Ankara Developmental Screening Inventory (ADSI) and the Guide for Monitoring Child Development (GMCD) at 12 months of age. RESULTS: Clinically defined acute symptomatic seizures were diagnosed with prompt conventional EEG / amplitude-integrated EEG in preterm (92.3%) and term neonates (81.4%) with etiology-specific diagnoses of NE. There were no differences between the study groups regarding seizure semiology and EEG characteristics. A primary adverse outcome was defined in 22 (41.5%) of the cohort. However, only 15.3% of infants had an unfavorable functional outcome with ADSI at 12 months. Among the survivors, there was no significant difference between the study groups regarding ADSI scores. The GMDC test revealed normal development in 50% of survivors with seizures in the preterm group and 83% in the term group. CONCLUSION: There was no significant difference between the characteristics of functional outcomes at 12 months in preterm and term neonates with NE for clinical seizures.
RESUMEN
BACKGROUND: The prefeed gastric residual check (GRC) when increasing the amounts of feeds given via orogastric and nasogastric tubes as a precaution for necrotizing enterocolitis (NEC) and intestinal intolerance is a routine procedure. However, it is mostly misleading, and recently, there has been a tendency not to check prefeed residuals. METHODS: We changed our nutrition protocol at the end of 2018 to start minimal enteral feeds (MEFs) and increase feeds without GRCs. We investigated the effects on the incidence of NEC, complications, time to reach full feeds, and growth parameters RESULTS: We compared the results of 60 preterm infants at ≤35 weeks' gestational age (group 1: 2016-2017, cared for with GRC) and 77 preterm infants (group 2: 2019, without routine GRCs). No differences in incidence of NEC and complications were observed. Group 2 started enteral feeds 3 days earlier, reached total feeds 6 days earlier (P < 0.01), and had higher weight (P < 0.01) and head circumference gain (P < 0.01). Extrauterine growth restriction was significantly less for head circumference and also insignificantly less for weight and height. CONCLUSION: We conclude that starting MEFs earlier and omitting routine GRCs in clinically stable preterm infants accelerate enteral feeds and growth parameters.

BACKGROUND: Providing medical students with opportunities for research experience is challenging for medical schools in developing countries. The Research Training Program (RTP), which is carried out in Ege University Faculty of Medicine (EUFM) parallel to the core curriculum, aims to improve the scientific competencies of the highly motivated students and to provide them with the opportunity to conduct a research. The purpose of this project is to evaluate RTP through the perspectives of students and faculty members. METHODS: This phenomenological study included two groups; students of RTP and faculty members who contributed to the program. Interviews were conducted with the research group whose selection was determined by maximum variation technique. Interviews with new individuals continued until data saturation was reached. Interpretative data analysis started with close reading of the transcripts and generating a list of codes. Coding by two independently, developing categories and themes were the following steps. RESULTS: Twenty-one RTP students and 14 faculty members were interviewed. The main motivation for students to participate was the desire to learn how to do research. The introduction course providing the students with the basic competencies needs to be improved in terms of practical activities. It was reported that during the project process students needed intensive guidance especially in finding a research topic and a mentor. The students' lack of time, deficit of enough mentoring and the fact that conducting a research does not provide a competitive advantage for residency are important obstacles to the completion of the program. The most frequently mentioned achievement of the students is to learn all the stages of the research as well as getting acquainted with critical thinking. CONCLUSIONS: This research showed that it was realistic to implement research programs for highly motivated students in medical schools with conditions like those in EUFM. The solution of mentor shortage emerged in this study is dependent on the adoption of student research as a national policy. Getting acquainted with the interrogative thinking style, conducting research, and making lifelong learning a core value are more important outcomes of research programs than the number of completed projects.

AIM: In this study; we aimed to see the time-dependent changes in the macronutrient content of early frozen breast milk and also to compare it with fresh breast milk in the first 6 months. MATERIALS AND METHOD: We evaluated the milk samples of 43 mothers who delivered at term. Milk samples after the first 15 days following delivery were expressed and collected dividing into seven aliquots to be stored frozen at -20 °C. Every month freshly collected new milk samples were analyzed together with one aliquot of the stored samples, up to 6 months. The energy, protein, lipid, and carbohydrate contents of samples were analyzed by Miris Human Milk Analyzer. RESULTS: In the first 3 months, fresh milk had higher caloric and lipid content when compared to frozen samples. The protein content of fresh milk decreased after 2 months and became lower than frozen samples. The energy and lipid content of frozen milk decreased over time but protein and carbohydrate contents stayed stable. Carbohydrate content of fresh and frozen samples did not show major changes. CONCLUSION: It may be more suitable to consume the frozen milk that was collected in the early weeks of delivery within first 2 months.

OBJECTIVE: Endotracheal intubation is a frequent procedure performed in neonates with respiratory distress. Clinicians use different methods to estimate the intubation insertion depth, but, unfortunately, the improper insertion results are very high. In this study, we aimed to compare the two different methods (Tochen's formula = weight in kilograms + 6 cm; and nasal septum-tragus length [NTL] + 1 cm) used to determine the endotracheal tube (ETT) insertion depth. STUDY DESIGN: Infants who had intubation indications were enrolled in this study. The intubation tube was fixed using the Tochen formula (Tochen group) or the NTL + 1 cm formula (NTL group). After intubation, the chest radiograph was evaluated (above T1, proper place, and below T2). RESULTS: A total of 167 infants (22-42 weeks of gestational age) were included in the study. The proper tube placement rate in both groups was similar (32.4 vs. 30.4% for infants < 34 weeks of gestational age and 56.8 vs. 45.0% in infants > 34 weeks of gestational age). The ETT was frequently placed below T2 at a higher rate in infants with a gestational age of <34 weeks, especially in the NTL group (46% in the Tochen group and 60.7% in the NTL group). CONCLUSION: The NTL + 1 cm formula led to a higher rate of ETT placement below T2, especially in infants with a birth weight of <1,500 g. Therefore, more studies are needed to determine the optimal ETT insertion depth.

BACKGROUND: Congenital heart disease (CHD) is the most common congenital malformation group and is the leading cause of newborn mortality in developed countries. Most of the infants with CHD develop preoperative or postoperative acute kidney injury (AKI). Acute kidney injury may develop before the serum creatinine rise and oliguria. Urinary biomarkers such as kidney injury molecule-1 (KIM-1), neutrophil gelatinase-associated lipocalin (NGAL), interleukin (IL)-18, and cystatin C may predict AKI in patients with critical CHD (CCHD) before the serum creatinine rise. In this study, we aimed to determine the AKI incidence among newborn patients with CCHD and investigate the predictivity of urinary biomarkers for AKI. METHODS: Newborns with a gestational age >34 weeks and birth weight >1500 g with a diagnosis of CCHD were enrolled in the study. Blood and urine samples were collected at birth, during the first 24-48 h, and in the preoperative and postoperative periods. RESULTS: A total of 53 CCHD patients requiring surgery during the neonatal period were enrolled in the study. The 24-48 h KIM-1 levels of the cases with exitus were higher (P = 0.007). The 24-48 h cystatin C and preoperative NGAL levels were higher in patients with postoperative AKI (P = 0.02). DISCUSSION: In newborns with CCHD, high KIM-1 levels may predict mortality, whereas high cystatin C and preoperative NGAL levels may be indicative of AKI. These biomarkers deserve further investigation in larger study populations.
RESUMEN
Appropriate treatment of neonatal seizures with an effective therapy is important in reducing long-term neurologic disabilities. Sixty-seven neonates, who received intravenous (IV) levetiracetam (LEV) as first-line therapy for treating seizures between 2013 and 2017 were evaluated retrospectively to investigate the efficacy of LEV and its neurodevelopmental outcome at 12 months of age. Of the 67 neonates (44 preterm and 23 term babies) evaluated for seizures, 55 (82%) had a defined etiology. EEG confirmation was obtained in 36 (57.1%) of the neonates with clinical seizures. On the 7th day of the treatment (mean seizure control time 7.4 ± 15.1 days), LEV was effective as monotherapy in 43 (64%), whereas add-on therapy was required in 24 (36%) neonates. At the 1-year follow-up, 76% of infants achieved drug-free state, nine (18%) infants remained on LEV monotherapy and three (6%) needed add-on therapy. Neurodevelopmental outcome of the infants was assessed with Ankara Development Screening Inventory and results suggested favorable neurodevelopmental outcome in 69.7% of the infants with at the end of the 1-year follow-up with LEV monotherapy. In conclusion, this retrospective cross-sectional study demonstrated that IV LEV is an effective first-line therapy for treating neonatal clinical seizures and LEV monotherapy effect was sustained during the first year follow-up.

BACKGROUND: Apoptosis that occurs after hypoxia/reoxygenation (H/R) has an important role in the pathogenesis of necrotizing enterocolitis (NEC). Telomerase activity, showing the regeneration capacity, may also be important in the recovery process. Therefore, we aimed to investigate the effects of insulin-like growth factor-1 (IGF-1) and erythropoietin (EPO) on apoptosis and telomerase activity in an H/R model. METHODS: Young mice were divided into four groups each containing ten Balb/c mice. Group 1 (H/R) were exposed to H/R; group 2 and group 3 were pretreated with IGF-1 and EPO, respectively, for 7 days before H/R. Group 4 served as control. Intestinal injury was evaluated by histological scoring and assessment of apoptosis was performed by terminal deoxynucleotidyl transferase dUTP nick-end labeling (TUNEL) test. Proapoptotic and antiapoptotic gene expressions and telomerase activity were analyzed by real-time PCR. RESULTS: IGF-1- and EPO-treated animals had decreased histological damage and apoptosis, confirmed by TUNEL test and caspase activity. Telomerase activity was increased in these animals in addition to increased expression of antiapoptotic genes. However, proapoptotic gene expressions were not statistically different. CONCLUSIONS: The protective effects of IGF-1 and EPO in H/R damage may be through increased expression of antiapoptotic genes and increased telomerase activity, especially for IGF-1. IMPACT: This is a comprehensive study measuring various variables, namely IGF-1, EPO, apoptosis, apoptotic and antiapoptotic genes, and telomerase activity in the NEC model. The intestinal protective effects of IGF-1 and EPO in H/R damage may occur through increased expression of antiapoptotic genes and increased telomerase activity. To the best of our knowledge, telomerase activity has not been investigated in the NEC model before. Regarding our results, novel strategies may be implemented for the early definitive diagnosis, robust preventive measures, and effective treatment modalities for NEC.

Aim: The aim of this study is to compare the efficiency of a new method called "finger feeding" with a well-known technique called syringe feeding for improving sucking skills and accelerating transition to breastfeeding in preterm infants. Materials and Methods: Totally 70 babies were included in this prospective randomized controlled study. Finger feeding method was applied in Group 1 (n = 35) and syringe feeding method was applied in Group 2 (n = 35). The COMFORTneo scale (CnS), oxygen saturation, pulse, respiratory rate, body temperature, amount of breast milk taken, and vomiting data were recorded before and after both applications. Hospitalization period and time elapsed for complete transition from both methods to breastfeeding were also recorded. Results: There was no statistical difference for birth weights, mean gestational age, and vital signs recorded before and after feeding between two groups. Predicted comfort and distress scores of Group 1 determined by the CnS were significantly lower than those of Group 2. This means that babies in the finger feeding group had better comfort than the those in Group 2 (p = 0.000). Time passed for transition to breastfeeding was significantly shorter than that in Group 2 (19.4 ± 15.0 days versus 29.7 ± 10.2 days, p = 0.000). Group 1 had lower amount of food leakage while feeding and their average weight gain at the end of 10th day was significantly higher (322.1 ± 82.3 g versus 252 ± 108.4 g, p = 0.004). They also were discharged earlier than Group 2 (25.8 ± 17.4 days versus 35.9 ± 13.0 days, p = 0.001). Conclusion: Finger feeding method is an effective way for increasing sucking abilities, accelerating transition to breastfeeding, and shortens duration of hospitalization in preterm infants.

The aim of our study to investigate clinical value of a set of neuropeptides (brain derived neurotrophic factor-BDNF, galanin and neuropeptide Y-NPY) in critically ill neonates. A total of 53 neonates (preterm: 26, term: 27) evaluated with lumbar pucture for etiologic evaluation were consequtively included into the study. Serum and CSF levels of the neuropeptides were measured in the first 48 h of life. All infants were prospectively followed for prognostic outcome (survival and neurodevelopmental) at the first year of life. The study cohort was categorized into four groups with respect to seizure development; preterm neonates with or without seizure and term neonates with or without seizure. Mean CSF levels of NPY (pg/ml) were significantly higher in term neonates with than those without seizures (389.76 vs. 122.66) and galanin (3.31 vs. 1.55) respectively. Term neonates with seizures had significantly higher serum levels of NPY (ng/mL) as compared with neonates without seizures (54.00 vs. 9.10). No significant difference was noted in serum and CSF levels for the set of neuropeptides in neonates with respect to prognostic outcome. Serum NPY and CSF NPY and galanin levels have a potential role for detection of clinical seizures in term neonates.

OBJECTIVE: To determine the reference ranges of presepsin in term and preterm neonates without infection, with respect to gestational and postnatal age, within the first 28 days of life. METHODS: A total of 144 neonates born at 24-42 weeks' gestation, including healthy term and preterm neonates without clinical signs or symptoms of infection, were included in this prospective observational study. Presepsin measurements included cord blood levels and serum levels on postnatal days 1, 3, 5, 7, 14, 21, and 28. RESULTS: The presepsin values corresponding to the 10th percentile ranged from 240.8 pg/mL (on day 1) to 129.9 pg/mL (on day 28), whereas those corresponding to the 90th percentile ranged from 725.8 pg/mL (on day 1) to 471.6 pg/mL (on day 28). Significantly higher presepsin levels were observed in cesarean deliveries than in spontaneous deliveries (p: 0.012 to <0.001), in gestational ages ≤ 32 weeks than in gestational ages ≥37 weeks (p: <0.05 to <0.001), and in cases with a maternal history of chorioamnionitis than in those without (p: <0.05 to <0.001). CONCLUSION: In conclusion, our findings revealed, for the first time, the reference ranges of presepsin in healthy term and preterm neonates without infection with respect to gestational and postnatal age, sex, and body weight. Presepsin levels within the first 28 days of life seem likely to be affected by the type of delivery, gestational and postnatal age, birth weight, and presence of respiratory distress syndrome or maternal chorioamnionitis.

Background: Renal transplantation not only prolongs survival but also improves quality of life and fertility, particularly in patients with end-stage renal disease. The aim of this study was to evaluate the renal and perinatal outcomes of pregnancy after renal transplantation at a high volume academic tertiary hospital.Methods: Fifty-one renal transplant patients (RTPs) who experienced pregnancy after transplantation and received care at Ege University Hospital between January 1995 and December 2017 were retrospectively identified. Data on demographics, comorbidities, and clinical perinatal outcomes were analyzed.Results: The median age of expectant mothers with renal transplantation was 30.51 ± 5.28 years (range 23-41). The mean interval between discontinuing birth control methods and the last menstrual period was 22 months. Preeclampsia occurred in six pregnancies (11.5%), and 43 of 52 pregnancies resulted in live births (82.6%). The mean gestational age at birth was 36.35 ± 2.36 weeks (range: 26-38). A total of 15 births were preterm deliveries (28.8%). Intrauterine growth retardation (IUGR) was detected in four cases. The mean birth weight was 2664.58 ± 613.99 g (range: 600-3.800 g). Twelve newborns were hospitalized in the neonatal intensive care unit (23%). A significant inverse correlation between birth weight and preconception serum creatinine level was found (p < .001; r = -0.532). An inverse correlation between the interval between transplantation and pregnancy and low postpartum serum creatinine level was established significantly (p < .05; r = -0.331). In addition, an inverse correlation between preconceptional serum creatinine and postpartum serum creatinine in the first year was found statistically significant (p < .001, r = -0.681).Conclusion: Even though pregnancy does not seem to adversely affect renal graft function, risks of perinatal as well as obstetrical complications should not be ignored. Pregnancies in RTPs should be followed closely by a multidisciplinary team of experts to minimize perinatal complications before and during pregnancy.

PURPOSE: Feeding intolerance is one of the most frequent problems among preterm infants. These infants are fed with expressed breast milk or preterm formulas of which the temperature is not routinely measured. In this study, we aimed to examine the effects of feeds with warm milk versus room temperature milk in preterm infants. MATERIALS AND METHODS: Infants with a birth weight ≤1,500 g or gestational age ≤34 weeks were included in the study and assigned to two different feeding temperature groups (22-24°C and 32-34°C). Some infants in both groups were exclusively breast milk-fed, and some received breast milk and artificial milk (mixed feeding). Feeding tolerance of infants in both groups and the consequences were evaluated. RESULTS: In total, 80 preterm infants (group 1 fed with milk at 22-24°C, n = 40; group 2 fed with milk at 32-34°C, n = 40) were prospectively included in the study. There was a slight decrease in gastric residual frequency in infants fed with breast milk in group 2. Apnea was significantly more frequent in group 1 (p = 0.006), and these infants needed more anti-reflux treatment (p = 0.013). CONCLUSION: According to our results, warming enteral feeds close to body temperature are encouraging especially due to the decrease in gastric residual frequency, apnea of prematurity, and need for anti-reflux treatment. More studies may confirm the positive effect of warm enteral feeds on feeding tolerance in preterm infants.

Cytomegalovirus (CMV), is the most common cause among congenital infections and is the most seen etiology in long-term sensorineural hearing loss (SNHL) and neurological impairment. Congenital CMV infection (CCMV) was reported in 0.15-2.2% of live-borne neonates in studies from different countries. A significant proportion of infected infants are asymptomatic after birth and might only be detected by routine screening methods during the new born period. The aim of this study was to screen the saliva of live-born neonates with areal-time PCR based method for the detection of CCMV in our hospital. Saliva samples collected in half an hour after birth by dry dacron swabs and were evaluated for CMV DNA (Rt-PCR, Abbott Molecular USA) from 1000 babies born in Ege University Faculty of Medicine Hospital Obstetrics Clinic between October 2015-October 2017. For the confirmation of CCMV, saliva positive newborns were evaluated with the same method for CMV DNA from their urine or blood within 21 days. All newborns were screened for sensorineural hearing tests. Subjects were 497 girls (49.7%) and 503 boys (50.3%), with a mean weight of 3116.8 g and mean of 37.61 birth week. CMV DNA was positive in the saliva of 16 newborns (1.6%). Fourteen newborns were weakly positive for CMV DNA in their saliva and were not confirmed for CCMV infection. Congenital CMV was confirmed in only two (0.2%) with the CMV DNA results in urine and/or blood samples. One of the two newborns with CCMV was symptomatic and had a neurosensorial hearing loss. The other one was asymptomatic. Saliva samples, taken immediately after birth with a noninvasive and easy method for the detection of CMV DNA is very important for diagnosis of CCMV. Positive samples should be confirmed with CMV DNA in urine or blood samples of these newborns. In this study, detection of positivity in saliva samples that were confirmed with other samples of our newborn population for CCMV was 0.2%. The specific diagnosis for CCMV in newborns with a noninvasive and easy collecting sample is important to avoid sequelae and for public health concerns.
