[Investigation of congenital CMV infection with the presence of CMV DNA in saliva samples of new born babies]. / Yenidogan bebeklerin tükürük örneginde CMV DNA varligi ile konjenital CMV enfeksiyonunun arastirilmasi.

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.

Reference values of anthropometric measurements in healthy late preterm and term infants

Background/aim: Geographical distribution, ethnicity, and other socioeconomic factors may affect anthropometric measurements, and for that reason each society should determine their own measurements accounting for those factors. In this study, we aimed to determine the anthropometric measurements of healthy late preterm and term infants to compare the results with other national and international studies. Materials and methods: This sectional study was carried out among 1197 infants born with a gestational age of ≥35 weeks. Chest circumference, ear length, foot length, palmar length, middle finger length, philtrum distance, inner and outer canthal distances, and palpebral fissure length were measured in the first 24 h of life. Results: All measurements of late preterm infants were smaller than those of term infants (P ˂ 0.05). Compared with male infants, the chest circumference, ear length, foot length, palmar length, philtrum distance, and inner canthal distances of the female infants were lower (P ˂ 0.05). No significant differences were found between male and female infants' middle finger length, outer canthal distance, and palpebral fissure length measurements. Percentile values for all measurements of 35­42-week male and female infants were described. Conclusion: These measurements of male and female infants born between 35 and 42 weeks may be useful for early detection of syndromes by detecting anatomical abnormalities in our population.

The serial changes of perfusion index in preterm infants with patent ductus arteriosus: is perfusion index clinically significant?

BACKGROUND: Perfusion Index (PI) which reflects the peripheral blood flow may help early detection and treatment decision of hemodynamically significant patent ductus arteriosus (hsPDA) in preterm infants. The present study is designed to analyze the usefulness of PI level in early detection of hsPDA in preterm infants. METHODS: Preterm infants born before 36 gestational weeks were assessed for PI and simultaneous echocardiography. Based on echocardiography, each infant is categorized into no-PDA (group 1), non-hsPDA (group 2) and hsPDA (group 3). Heart rate (HR), mean arterial pressure (MAP), body temperature and oxygen saturation (SpO2) and concomitant PI were measured on days 1, 2, 3 and 4. RESULTS: In all preterm infants (N.=42) PI significantly increased from 0.7 on day 1 to 1.4 on day 4. The HR did not change by the days; however, the MAP increased on days 3 and 4 compared to day 1. In hsPDA group, the median PI was 0.7 (IQR, 0.4) on day 1 compared to 0.9 (IQR, 0.2) on day 2. PI is significantly lower in hsPDA group compared to no-PDA group on day 1 and 2; however, this difference disappeared at 48 hour on the intravenous ibuprofen treatment (on day 3 and 4). CONCLUSIONS: PI may predict the perfusion disorder and help to decide for treatment of hsPDA and was also helpful to monitor the response to treatment in hsPDA patients.

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.

Evaluation of device-associated infections in a neonatal intensive care unit.

Device-associated infections are common in Neonatal Intensive Care Units (NICUs) in accordance with the frequent use of invasive devices, and they must be continuously and closely monitored for infection control. Six hundred newborn infants hospitalized longer than 72 hours in Ege University Children's Hospital NICU between January 2008 and December 2010 were prospectively followed for occurrence of device-associated infections (central venous catheter- and umbilical catheter-associated blood stream infections [CVC/UC BSI] and ventilator-associated pneumonia [VAP]). In a total of 10,052 patient days, the VAP rate was 13.76/1000 ventilator days with a ventilator utilization ratio of 0.29, and the CVC/UC BSI rate was 3.8/1000 catheter days with a catheter utilization ratio of 0.24. The CVC/UC BSI rate was lower than national averages, being close to rates reported from developed countries. The VAP rate was higher than the national and international rates and was associated with prolonged mechanical ventilation and very low birth weight. VAP also appeared to be an important risk factor for mortality. The most frequent agents were gram-negative pathogens for VAP and coagulase-negative staphylococci for CVC/UC BSIs, with resistance patterns similar to the previous years. In conclusion, with device utilization rates similar to those in developed countries, our CVC/UC BSI rate was comparable, but the VAP rate was higher than that of the developed countries. Necessary precautions are urgently needed to decrease VAP rates and VAP-related mortality.

Early Immunomodulatory Effects of Different Natural Surfactant Preparations in Preterms With Respiratory Distress.

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.

Omitting routine gastric residual checks may help to accelerate enteral feeds and postnatal growth in stable preterm infants.

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.

Efficacy of levetiracetam as first-line therapy for neonatal clinical seizures and neurodevelopmental outcome at 12 months of age.

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.

Hindmilk for procedural pain in term neonates.

The aim of this study was to investigate whether repeated doses of hindmilk were effective for pain relief during routine heel stick in term neonates. Infants enrolled in this double-blind placebo-controlled study were randomly assigned to hindmilk, 12.5% sucrose and distilled water groups. Infants were given 1 ml of the test solution 1 minute prior to, immediately before and 1 minute after the heel stick. Pain responses were assessed by physiologic and behavioral parameters and also according to the Neonatal Facial Coding System (NFCS). There were significant reductions in crying time, duration of the first cry and tachycardia, time needed for return to baseline heart rate, and the average and 1- and 5-minute NFCS scores in the hindmilk group when compared with the distilled water group. When the hindmilk group was compared to the sucrose group, only the NFCS scores at 1 and 2 minutes reached statistical significance in favor of the sucrose group. Repeated dose hindmilk administration is an effective analgesic intervention in term newborns during heel stick. Although the analgesic effect of 12.5% sucrose is slightly superior, hindmilk may be considered as a physiologically suitable alternative to sucrose.

Reference ranges of presepsin (soluble CD14 subtype) in term and preterm neonates without infection, in relation to gestational and postnatal age, in the first 28 days of life.

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.

Comparison of the Finger Feeding Method Versus Syringe Feeding Method in Supporting Sucking Skills of Preterm Babies.

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.

Clinical value of a set of neuropeptides in term and preterm neonates with seizures: Brain derived neurotrophic factor, galanin and neuropeptide Y.

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.

The Change of Perinatal Mortality Over Three Decades in a Reference Centre in the Aegean Region: Neonatal Mortality has decreased but Foetal Mortality Remains Unchanged.

BACKGROUND: Perinatal, foetal and neonatal mortality statistics are important to show the development of a health care system in a country. However, in our country there are very few national and regional data about the changing pattern of perinatal neonatal mortality along with the development of new technologies in this area. AIMS: Evaluation of the changes in mortality rates and the causes of perinatal and neonatal deaths within years in a perinatal reference centre which serves a high-risk population. STUDY DESIGN: Cross-sectional retrospective study. METHODS: The perinatal, neonatal and foetal mortality rates in the years 1979-1980 (1st time point) and 1988-1989 (2nd time point) were compared with the year 2008 (3rd time point). The causes of mortality were assessed by Wigglesworth classification and death reports. The neonatal mortality in the neonatal intensive care unit was also calculated. RESULTS: Foetal mortality rates were 44/1000, 31.4/1000 and 41.75/1000 births, perinatal mortality rates were 35.6/1000, 18.8/1000 and 9/1000 births, and neonatal mortality rates were 35.6/1000, 18.8/1000 and 9/1000 live births for the three study time points, respectively. The mortality rate in neonatal intensive care unit decreased consistently from 33%, to 22.6% and 10%, respectively, together with decreasing neonatal mortality rates. The causes of perinatal deaths were foetal death 85%, immaturity 4%, and lethal congenital malformations 8% according to Wigglesworth classification in 2008, showing the high impact of foetal deaths on this high perinatal mortality rate. Infectious causes of neonatal deaths decreased but congenital anomalies increased in the last decades. CONCLUSION: Although neonatal mortality rate decreased significantly; foetal mortality rate has stayed unchanged since the late eighties. In order to decrease foetal and perinatal mortality rates more efficiently, reducing consanguineous marriages and providing better antenatal care for high risk pregnancies are needed.

Mannose-binding lectin may affect pregnancy outcome.

Mannose-binding lectin (MBL) is a component of the innate immune system and acts as a complement activator through the lectin pathway. Genetic variations of MBL and low MBL levels cause several infection problems, which may also be related to pregnancy problems. We aimed to investigate the role of MBL gene codon 54 polymorphism and serum MBL levels in pregnancy problems and premature delivery. In this prospective study, MBL gene codon 54 polymorphism and serum MBL levels were studied in 45 mothers who delivered earlier than 35 gestational weeks. The frequency of MBL gene codon 54 variant allele B was much higher (homozygous 4.4% and heterozygous 33.3%) in the study group mothers than the previously reported frequency in the healthy Turkish population (homozygous 2-6%, heterozygous 12-20%). MBL variant allele B frequency was closely related to low MBL levels (<0.1 µg/ml), vaginitis and increased IL-6 levels. The median MBL levels were lower than the critical level of 0.1 µg/ ml in study mothers who had recurrent miscarriage, infertility, preeclampsia, gestational diabetes mellitus, preterm premature rupture of membranes with duration of longer than 72 hours, tocolysis, histological chorioamnionitis, urinary tract infection and vaginitis. MBL gene codon 54 variant allele B is related to low serum MBL levels, increased IL-6 levels, genitourinary infections and may cause pregnancy-related problems such as infertility, recurrent miscarriage and preterm delivery.

Both parents of neonatal intensive care unit patients are at risk of depression.

Postpartum depression is a serious disorder that can be seen not only in mothers but also in fathers; therefore, it negatively affects the whole family. Hospitalization in the neonatal intensive care unit (NICU) is a stress factor for the parents and contributes to depression. We aimed to detect the frequency of postpartum depression and the contributing risk factors in parents of NICU patients. The Edinburgh Postnatal Depression Scale was used for mothers and the Beck Depression Inventory was performed for fathers in the 2nd and 6th weeks after delivery. At the 2nd week, maternal depression frequency was found as 38.3%, with a mean score [ms] of 10.97±6.93. At the 6th week, maternal depression frequency was 33.3% (ms: 9.57±5.78). Paternal depression was 11.7% (ms= 7.13±7.35) at the 2nd week and 10.0% (ms: 6.50±5.79) at the 6th week. The frequency of maternal depression remained stable, but mean maternal depression scores were decreased at the 6th week compared to the 2nd week (p=0.023). However, paternal depression scores were similar in both periods (p=0.428). The infants' disease severity at admission to the NICU, as shown by SNAPPE-II risk scores, was positively correlated with Edinburgh depression scores of the mothers at the postnatal 2nd week, but not at the 6th week. In conclusion, NICU stay of high-risk infants may cause depression in their mothers and fathers, even in the absence of any previous risk factor. Although at a lower rate than in mothers, fathers may also suffer from depression. Parental depression screening and whole family support during NICU hospitalization are strongly recommended.

Factors affecting bilirubin levels during first 48 hours of life in healthy infants.

OBJECTIVE: To investigate the relationship of delivery type, maternal anesthesia, feeding modalities, and first feeding and meconium passage times with early bilirubin levels of healthy infants. METHODS: Cord, 24 hours' and 48 hours' total bilirubin levels were measured in 388 study infants. RESULTS: Infants born with cesarean section were fed later and more often had mixed feeding. First meconium passage was delayed with general anesthesia. Cord, 24 and 48 hours' bilirubin levels were not correlated with first feeding time, meconium passage time, mode of delivery, existence and type of anesthesia, and feeding modalities. Being in high intermediate risk zone at 72 hours of Bhutani's nomogram was only related to first feeding time and high cord bilirubin level. Late preterm infants were more frequently born with cesarean section and offered supplementary formula. Therefore, first meconium passage times and bilirubin levels were similar in the late preterm and term infants. CONCLUSIONS: Type of delivery or anesthesia, late prematurity, feeding modalities, and first meconium passage time were not related to early bilirubin levels in healthy neonates, but delayed first feeding and high cord bilirubin levels were related to be in higher risk zone for later hyperbilirubinemia.

Kluyvera cryocrescens sepsis in a preterm infant.

Kluyvera cryocrescens, formerly accepted as a benign saprophytic microorganism, is an opportunistic pathogen and its infection is very rare in humans. This report describes a preterm infant born at 30 weeks of gestational age and successfully treated for K. cryocrescens sepsis in the 3rd week of life. To our knowledge, this is the first case of K. cryocrescens sepsis in a newborn. The potential of K. cryocrescens as a serious pathogen should be recognized especially in patients such as preterm infants in whom the prognosis may be compromised without appropriate treatment.
