RESUMO
OBJECTIVE: To compare the effect of umbilical cord milking and early cord clamping on thymic size, and neonatal mortality and morbidity in preterm infants. METHODS: This single-center, prospective, double-blind, randomised controlled study was conducted at Baskent University, Konya Education and Research Centre, Konya, Turkey, between October 2015 and April 2016. Pregnant women who delivered before 32 weeks of gestation were randomised to receive umbilical cord milking (group 1) or early cord clamping (group 2). Ultrasonographic evaluation was performed in each newborn by an experienced radiologist within the first 24 hours of life. Thymic si ze was estimated in l ine with literatu re. SPSS 15 was u sed for a ll data analyses. RESULTS: There were 38 subjects in group 1 and 37 in group 2. There were as many infants in the two groups (p>0.05) The haemoglobin levels was higher in group 1, but not significantly (p=0.213). The absolute neutrophil count in group 1 was significantly lower (p= 0.017) than group 2. In terms of neonatal mortaility and morbidity, there were no significant differences between the groups (p>0.05). CONCLUSIONS: Umbilical cord milking was not associated with thymic size during the the first 24h of life.

OBJECTIVE: To identify how acupressure on the acupoint Yintang (EX-HN 3) impacts oxygen saturation, pulse rate, and peripheral perfusion in term-born infants without underlying disease. METHODS: Infants born between weeks 37 and 42 of gestation were included in this study. The polyclinic's neonatology room was noise-controlled and made half-dark to prevent the perfusion index from being confounded. A pulse oximeter was linked to the baby's left lower extremity. Acupressure was applied on Yintang (EX-HN 3) for 30 s clockwise, held for 30 s, and then acupressure was applied for another 30 s counterclockwise. The baby's SaO2, pulse rate, and perfusion index were recorded for each minute before and after acupressure. RESULTS: When pre- and post-acupressure pulse rate values were compared, a significant decrease in pulse rate values after acupressure application was observed. When pre- and post-acupressure oxygen saturation values were compared, a significant increase in post-acupressure oxygen saturation was observed. In addition, peripheral perfusion increased significantly after acupressure. CONCLUSION: Acupressure application has been used in traditional medicine for many years. However, it is not yet widely used in modern medicine. This study shows the impact of acupressure on neonatal skin perfusion, oxygen saturation, and pulse rate.

AIM: Despite extensive research, there is still controversy regarding the time at which sucking and swallowing functions mature in preterm infants. This study aimed to evaluate maturation using the noninvasive method of swallowing sound. METHODS: We compared 52 preterm infants of between 27 and 36 weeks' gestational age with a control group of 42 healthy full-term infants. Feeding performance was based on swallowing data collected during two-minute audio recordings. The following variables were generated for each evaluation: total number of swallows, total number of rhythmic swallows, total number of resting intervals, average time between resting intervals, average time between swallows, average time between rhythmic swallows, maximum number of rhythmic swallows and volume of milk ingested. The dependency of the variables on postmenstrual age was also investigated. RESULTS: The volume of milk ingested by the preterm infants and the maximum number of rhythmic swallows were positively correlated with postmenstrual age (PMA). The preterm infants reached the 10th percentile of the control infants at 34-35 weeks' PMA and were not significantly different from the control infants at 38-40 weeks' PMA. CONCLUSION: Swallowing sound can be used to assess feeding maturation in preterm infants during neonatal intensive care unit follow-up.

BACKGROUND: This study aimed to examine the differences between arterial and inferior caval vein oxygen saturation, fractional oxygen extraction, and the shunt index, which were calculated in the diagnosis of patent ductus arteriosus. METHODS: Twenty-seven preterm infants were included in this study and were divided into two groups according to patent ductus arteriosus. Among them, 11 (41%) infants had haemodynamically significant patent ductus arteriosus and 16 (59%) did not have significant patent ductus arteriosus. Synchronous arterial and venous blood gases were measured during the first post-natal hours after the insertion of umbilical catheters. The differences between arterial and inferior caval vein oxygen saturation, inferior body fractional oxygen extraction, and the shunt index were calculated. Echocardiography was performed before the 72nd hour of life in a selected group of patients who had haemodynamically significant patent ductus arteriosus. Ibuprofen treatment was administered to patients with patent ductus arteriosus. Echocardiography was performed on the 72nd hour of life in preterm infants without any clinical suspicion of patent ductus arteriosus. RESULTS: The early measured differences between arterial and inferior caval vein oxygen saturation and inferior body fractional oxygen extraction were found to be lower and the shunt index was found to be higher in the haemodynamically significant patent ductus arteriosus group than in the group without haemodynamically significant patent ductus arteriosus. CONCLUSION: We found that the shunt index, calculated in the first hours of life as ≥63%, predicted haemodynamically significant patent ductus arteriosus with a sensitivity of 78% and specificity of 82% in preterm newborns.

BACKGROUND: The objectives of this study were to assess the preoperative and postoperative serum brain- derived neurotrophic factor (BDNF) levels in neonates undergoing surgery for congenital heart defects (CHD). Also to explore the relationship between changes in BDNF levels and the impact of perioperative factors including intraoperative body temperature, aortic cross-clamp time, perfusion time, operation time, inotropic score, vasoactive inotropic score and lactate levels. METHODS: Forty-four patients with CHD and 36 healthy neonates were included in the study. Blood samples for serum BDNF levels were collected three times: preoperatively, and at 24 and 72 hours postoperatively from each patient in the operated group. Additionally, samples were collected once from each individual in the non-operated case group and the control group. Serum BDNF levels were analyzed using the Elabscience ELISA (Enzyme-Linked Immunosorbent Assay) commercial kit. Cranial ultrasonography (USG) was performed on all infants with CHD. Following cardiac surgery, patients underwent second and third cranial USG examinations at 24 and 72 hours postoperatively, respectively. RESULTS: Forty-four consecutive patients with CHD were divided into two groups as follows: the operated group (n=30) and the non-operated group (n=14). Although there were no differences in the baseline serum BDNF levels between the case and control groups, the preoperative serum BDNF levels were significantly lower in the patients operated compared to the non-operated patients. The serum BDNF levels at the 24th hour postoperatively were higher than the preoperative levels. However, no significant correlation was found between the serum BDNF levels at 24 and 72 hours postoperatively as well as the cranial USG findings at corresponding times. CONCLUSIONS: Serum BDNF levels were initially lower in neonates with CHD who underwent surgery, but increased during the early postoperative period. These results suggest that serum BDNF levels are influenced by CHD and the postoperative period.

OBJECTIVE: To evaluate the diagnostic potential of resistin in sepsis and to compare results with C-reactive protein (CRP) in infants < 32 weeks of gestation. STUDY DESIGN: A total of 64 infants were prospectively included in the study. Blood samples were collected for basal CRP and resistin within the first hour of life. When sepsis was suspected, samples were collected for CRP and resistin before the treatment was started (pretreatment CRP and resistin). On the third day of sepsis, CRP and resistin levels were measured for evaluating the treatment response (follow-up CRP and follow-up resistin). Culture-proven septic patients were divided into groups according to early or late-onset sepsis (EOS and LOS) and gram-negative or gram-positive sepsis (GNS and GPS). RESULTS: Pretreatment and follow-up resistin levels were significantly higher than basal resistin levels in both EOS and LOS groups (p < 0.01), with a positive correlation with CRP levels. To predict the GNS and GPS area under curve, values of pretreatment CRP and resistin were 0.714 and 0.984, respectively (p = 0.039). CONCLUSION: Resistin had a superior potential to that of CRP in the diagnosis of sepsis in preterm infants. Resistin may be used as an early marker for sepsis in premature infants.

Acid-base disturbances have been usually evaluated with the traditional Henderson-Hasselbach method and Stewart's physiochemical approach by quantifying anions of tissue acids (TA). It is hypothesized that an increase in tissue acids during metabolic acidosis would cause a compensatory decrease in the plasma chloride (Cl) relative to sodium (Cl-Na ratio) in order to preserve electroneutral balance. Therefore, we aimed to investigate the use of Cl-Na ratio as a bedside tool to evaluate the identifying raised TA in neonates as an alternative to complex calculations of Stewart's physiochemical approach. This retrospective study was conducted between January 2008 and December 2009. Infants were included in the study when blood gas analysis reveals a metabolic acidosis; pH <7.25 and sHCO(3) concentration was <22 mEq/L. The Cl-Na ratio, sodium-chloride difference (Diff(NaCl)), anion gap (AG), albumin-corrected AG (AG(corr)), strong ion difference (SID), unmeasured anions (UMA), and TA were calculated at each episode of metabolic acidosis. A total of 105 metabolic acidosis episodes occurred in 59 infants during follow-up. Hypochloremic metabolic acidosis occurred in 17 (16%) of samples, and all had increased TA. The dominant component of TA was UMA rather than lactate. There was a negative correlation between the Cl-Na ratio and SID, AG(corr), UMA, and TA. Also, there was a positive correlation between Diff(NaCl) and SID, AG(corr), UMA, and TA. Base deficit and actual bicarbonate performed poorly in identifying the TA. In conclusion, our study suggested that Diff(NaCl) and Cl-Na ratio are simple and fast, and may be an alternative method to complex Stewart's physiochemical approach in identifying raised UMA and TA in critically ill neonates.

Vitamin D is important for calcium homeostasis, muscle, and bone health. It has also immunomodulatory capacities in vivo and in vitro. Regulatory T cells (Treg) have been found to suppress a number of T cell-mediated immune disorders, including allergic responses and autoimmune diseases. This study aimed to investigate the correlation between 25-hydroxyvitamin D (25(OH)D) levels and the regulatory T cells in cord blood. The study group is comprised of 101 full-term newborn infants. Umbilical cord 25(OH)D levels and number and percentage of T lymphocyte, T helper, and Treg cells were measured. Infants were grouped according to 25-hydroxyvitamin D levels (25(OH)D <12 ng/ml and 25(OH)D >12 ng/ml) (converting factor of 25OHD level into SI unit, 2.6). Severe vitamin D deficiency (25(OH)D <12 ng/ml) was observed in 32% of the infants. There was no significant correlation between 25-hydroxyvitamin D levels and T cell number and percentages. There were also no significant differences in white blood cell, total lymphocyte count, T helper, and Treg cell percentage and number between groups. These results suggest that the serum level of 25-hydroxyvitamin D is not crucially involved in the correlation between vitamin D status and T cell regulation in cord blood.

BACKGROUND: The aim of this study was to determine the effects of severe hyperbilirubinemia on vestibular evoked myogenic potentials (VEMP). METHODS: A prospective study was designed. Seventeen term infants who suffered from severe hyperbilirubinemia in the first 5 postnatal days of age were included in the study group. The control group consisted of 17 healthy term infants. Audiological evaluation was performed, including tympanometry and transient evoked otoacoustic emissions, and VEMP tests. RESULTS: All newborns passed audiological evaluation. Biphasic waveforms of VEMP were obtained in all of the 34 infants who had been tested. Both latencies of p13 and n23 were significantly delayed in the severe hyperbilirubinemia group (P < 0.05). CONCLUSION: This pilot is the first study to show that severe hyperbilirubinemia causes delay in VEMP latencies. We suggest that severe hyperbilirubinemia might affect the vestibular nuclei or the integrity of the inferior vestibular nerve and vestibulospinal tract. Further studies need to explain the relation between hyperbilirubinemia and the vestibular system.

Recent investigations have shown that late preterm infants have increased risk for attention deficit hyperactivity disorder, neurosensory impairment, and emotional, behavior and learning problems. Vestibular evoked myogenic potential (VEMP) abnormality may partly contribute to these problems. Our aim was to measure VEMP in late preterm infants and to compare the findings between late preterm and term infants. Seventeen late preterm infants (mean gestational age: 35.11 weeks +/- 0.78) postnatal aged 8 weeks and 17 full-term (mean gestational age: 38.05 weeks +/- 0.96) infants postnatal aged 4 weeks underwent cervical (c)VEMP test without sedation. Mean latencies of p13 were calculated in all study subjects. cVEMPs were elicited in all late preterm and term infants. Mean latencies of p13 in late preterm and term infants were 14.53 and 13.34 ms, respectively. Mean latencies of n23 were determined as 23.18 ms and 19.92 ms for late preterm and term infants, respectively. There were statistically significant differences between late preterm and term infants for latency of p13 (p < 0.001) and latency of n23 (p < 0.000). Abnormal VEMP results might be related to a delay in the maturation of the sacculocollic pathways in late preterm infants.

OBJECTIVE: To evaluate analgesic effects of acupuncture in preterm neonates during minor painful procedures. METHODS: Ten preterm neonates requiring heel prick for blood gas analysis were enrolled in the study, which had a crossover design. Oxygen saturation, systolic and diastolic blood pressure, respiratory rate, heart rate, and crying duration were recorded before and after heel prick. Babies were given expressed breast milk before each procedure. Patients were randomly assigned to receive acupuncture or not, and the groups were crossed over on the following day, so that patients who had received acupuncture received only breast milk, and the previous breast milk only group received both acupuncture and breast milk. The neonatal infant pain scale (NIPS) was used for pain evaluation. RESULTS: Crying duration and NIPS pain scores during heel prick were lower in the neonates who had received acupuncture. CONCLUSION: Acupuncture is an effective method for the treatment of pain in neonates.

OBJECTIVE: This study aimed to compare the integrity of the efferent auditory pathways of newborns that had high hyperbilirubinemia levels and required treatment due to these and healthy newborns. METHODS: Term-born (37 weeks or later) infants that were brought to the Newborn Polyclinic of the Baskent University Hospital were included in the study. The study included a total of 84 infants including healthy newborns (n = 42) and those that had jaundice and were receiving phototherapy (n = 42). After conducting a general otorhinolaryngology examination on all newborns included in the study, Transient Otoacoustic Emission (TEOAE) test was carried out in the absence and presence of contralateral noise. The obtained contralateral suppression values were compared between the two groups. RESULTS: In the TEOAE test, the responses obtained at 1 kHz in the newborns receiving phototherapy were found to be lower. The difference between the groups was significant (p = 0.038). The rates of suppression presence at 2 kHz, 2.8 kHz and total OAE were found significantly higher (p < 0.05) in the group not receiving phototherapy. Among the phototherapy-receiving infants, the hyperbilirubinemia levels of the infants in whom suppression was obtained in the contralateral suppression test did not show a statistically significant difference in comparison to those in whom suppression was not obtained (p > 0.05). CONCLUSION: Based on the obtained data, hyperbilirubinemia may have a disruptive effect on the efferent auditory system in newborns. Consequently, we are of the opinion that, in addition to hearing screening in risky newborn infants, a MOC suppression test would be useful.

OBJECTIVE: The objective of this study is to investigate the effect of breast milk and sucrose on pain scores and perfusion index (PI) and to evaluate the alteration in pain and PI during retinopathy of prematurity (ROP) examination. METHODS: This prospective randomized controlled study was conducted with preterm infants who were born in our hospital, hospitalized in the neonatal intensive care unit and whose gestational week was <32 weeks and birth weight was <1500 g. The preterm infants who would undergo ROP examination were allocated to three groups according to simple randomization method as follows: group 1: only local anesthetic eye drops, proparacaine HCl ophthalmic solution 0.5%, group 2: proparacaine HCl ophthalmic solution 0.5% plus breast milk, and group 3: proparacaine HCl ophthalmic solution 0.5% plus sucrose 24%. Postductal PI, transcutaneous oxygen saturation and heart rate (HR) values were measured before the eye examination (0), at the 30th, 60th, and 90th seconds (s) of the eye examination and 30 s after lasting of the examination in all infants. Pain was evaluated using Neonatal Infant Pain Scale (NIPS) during the examination. RESULTS: Fifty-one preterm neonates were prospectively enrolled into the study. The HR was higher during and after the examination in all infants according to before the examination (p < .001). Transcutaneous oxygen saturation values significantly decreased during the examination in breast milk and sucrose groups (p = .001 and <.001, respectively). While PI was found to be lower at the 60th s compared to the 30th s of the examination in the proparacaine HCl group, no difference was found between the values before and after the examination. Perfusion index was found to significantly decrease during and after the examination compared to the values before the examination in the breast milk group. Perfusion index values were determined to significantly decrease at the 30th and 60th s of the examination in the sucrose group. The NIPS scores during the examination were determined to be higher compared to the NIPS scores before the examination in all groups (p< .001). In the intergroup comparisons, the NIPS scores were found to be higher in the sucrose group compared to the proparacaine HCl group at the 60th s of the examination and higher than that in the breast milk group at the 90th s of the examination (p = .02 and p = .01, respectively). CONCLUSIONS: The present study indicates that alterations may be seen in PI during the ROP examination; in other words, peripheral tissue perfusion could be affected. We consider that eye examination is a very painful procedure, and administering breast milk, sucrose or local anesthetic is not sufficient for reducing pain.

BACKGROUND: Healthcare-acquired infections (HAIs) in the neonatal period cause substantial morbidity, mortality, and healthcare costs. Our purpose was to determine the prevalence of HAIs, antimicrobial susceptibility of causative agents, and the adaptivity of the Centres for Disease Control and Prevention (CDC) criteria in neonatal HAI diagnosis. METHODS: A HAI point prevalence survey was conducted in the neonatal intensive care units (NICUs) of 31 hospitals from different geographic regions in Turkey. RESULTS: The Point HAI prevalence was 7.6%. Ventilator-associated pneumonia (VAP) and central line-associated bloodstream infections (CLABSI) and late onset sepsis were predominant. The point prevalence of VAP was 2.1%, and the point prevalence of CLABSI was 1.2% in our study. The most common causative agents in HAIs were Gram-negative rods (43.0%), and the most common agent was Klebsiella spp (24.6%); 81.2% of these species were extended spectrum beta-lactamase (ESBL) (+). Blood culture positivity was seen in 33.3% of samples taken from the umbilical venous catheter, whereas 0.9% of samples of peripherally inserted central catheters (PICCs) were positive. In our study, 60% of patients who had culture positivity in endotracheal aspirate or who had purulent endotracheal secretions did not have any daily FiO2 change (p = 0.67) and also 80% did not have any increase in positive end-expiratory pressure (PEEP) (p = 0.7). On the other hand, 18.1% of patients who had clinical deterioration compatible with VAP did not have endotracheal culture positivity (p = 0.005). CONCLUSIONS: Neonatal HAIs are frequent adverse events in district and regional hospitals. This at-risk population should be prioritized for HAI surveillance and prevention programs through improved infection prevention practices, and hand hygiene compliance should be conducted. CDC diagnostic criteria are not sufficient for NICUs. Future studies are warranted for the diagnosis of HAIs in NICUs.

Hepcidin is a regulatory peptide hormone acts by limiting intestinal iron absorption and promoting iron retention. Determining the level of hepcidin in anemia of prematurity might be important in preventing iron overload. This study aimed to determine serum levels of prohepcidin in newborns with anemia of prematurity, to assess the effect of a single erythrocyte transfusion on serum prohepcidin levels, and to determine the possible relationships between prohepcidin levels and serum iron and complete blood count parameters. Nineteen premature newborns with anemia of prematurity who had been treated with erythrocyte transfusions were included in this study. Just before, and 48 hours after, each transfusion, venous blood samples were collected from patients. Serum prohepcidin levels before and after erythrocyte transfusion were 206.5+/-27.3 and 205.7+/-47.1 ng/mL, respectively; no statistically significant differences were found. No significant differences existed before or after transfusion regarding serum total iron and ferritin levels, iron-binding capacity, or mean corpuscular hemoglobin concentration. No significant correlations existed between serum prohepcidin levels and other parameters, either before or after transfusions. Our results showed that there were no statistically significant differences between serum prohepcidin levels before and after a single erythrocyte transfusion in premature newborns.

Hyperbilirubinemia is one of the most widely seen cause of neonatal morbidity. Besides ABO and Rh isoimmunization, minor blood incompatibilities have been also been identified as the other causes of severe newborn jaundice. We report a newborn with indirect hyperbilirubinemia caused by minor blood group incompatibilities (P1, M, N, s and Duffy) whose hemolysis was successfully managed with intravenous immunoglobulin therapy. A thirty-two gestational weeks of preterm male baby became severely icteric on postnatal day 11, with a total bilirubin level of 14.66 mg/dl. Antibody screening tests revealed incompatibility on different minor groups (P1, M, N, s and Duffy (Fya ve Fyb)). On postnatal day thirteen, the level of bilirubin increased to 20.66 mg/dl although baby was under intensive phototherapy. After the administration of intravenous immunoglobulin and red blood cell transfusion, hemoglobin and total bilirubin levels became stabilised. Minor blood incompatibilities should be kept in mind during differential diagnosis of hemolytic anemia of the newborn. They share the same treatment algorithm with the other types hemolytic anemia. New studies revealed that intravenous immunoglobulin treatment in hemolytic anemia have some attractive and glamorous results. It should be seriously taken into consideration for treatment of minor blood incompatibilities.

Pain control is an important ethical issue to be considered and constitutes the basis of treatment in premature and term newborns. The inadequacy of pain control in these infants in neonatal intensive care units leads to neurodevelopmental and behavioral problems in the long term. For this reason, it is extremely important to raise awareness of the presence of pain in newborn infants, to reduce invasive procedures applied to infants as much as possible, and to minimize pain with non-pharmacologic or pharmacologic treatments when it is inevitable.
