Cerebral monitoring of very preterm infants with anterior cerebral artery resistive index and early NIRS.

BACKGROUND: The prediction of adverse conditions in the preterm neonatal brain might be improved by cerebral monitoring using combined measures of cerebral function, including oxygenation and blood flow parameters. To perform the consecutive measurements of the resistive index (RI) from the anterior cerebral artery (ACA) within the first week of life and to evaluate the association of these measurements with cerebral oxygen saturation (Csat) detected by near-infrared spectroscopy (NIRS). METHODS: This prospective cohort study enrolled very preterm infants, <32 weeks of gestational age, admitted to a tertiary neonatal intensive care unit. Csat levels were continuously monitored using NIRS for 72 h after birth. ACA RI measurements were obtained on the first, third, and seventh days of life by using transcranial Doppler ultrasound. These measurements were also compared between infants with and without unfavorable outcomes, including severe intraventricular hemorrhage (IVH) and early mortality. RESULTS: A total of 96 preterm infants with Csat and ACA RI measurements were analyzed. Age at birth was 28.3 ± 1.9 weeks and birth weight was 1090 ± 305 g. The mean Csat of the infants was 77.1% ± 8.2% during the first 72 h of life. Mean ACA RI values were 0.76 ± 0.10, 0.75 ± 0.08, and 0.77 ± 0.08 on the first, third, and seventh days of life, respectively. RI on the first day of life was significantly higher in infants delivered by cesarian section than in those delivered vaginally (0.77 vs. 0.69; p = 0.017). Infants who died earlier had significantly higher ACA RI values on the first day than infants who survived beyond the first 7 postnatal days (0.83 vs. 0.76; p < 0.001). DISCUSSION: There was no association between ACA RI and Csat in the early period of life. ACA RI values on the first postnatal day might be significant for predicting early mortality in very preterm infants.

Diagnostic Role of Systemic Inflammatory Indices in Infants with Moderate-to-Severe Hypoxic Ischemic Encephalopathy.

BACKGROUND: When the newborn brain is exposed to hypoxia, as in hypoxic ischemic encephalopathy (HIE), it causes an inflammatory response. A wide variety of inflammatory markers are therefore used in the diagnosis of HIE. OBJECTIVE: We aimed to determine the diagnostic role of systemic inflammatory indices in infants with moderate-to-severe HIE. We have also investigated the effect of hypothermia treatment over those indices. STUDY DESIGN: A retrospective cohort study of infants suffering from moderate-to-severe HIE was conducted in a tertiary-level neonatal intensive care unit between September 2019 and March 2021. Systemic inflammatory indices including systemic immune-inflammation index (SII), pan-immune-inflammation value (PIV), systemic inflammation response index (SIRI), neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and monocyte-to-lymphocyte ratio (MLR) were calculated for infants with HIE and controls at baseline, and after therapeutic hypothermia in those with HIE. RESULTS: A total of 103 infants (53 in the HIE group and 50 in the control group) were included in the study. Median gestational ages (GA) were 39 (37-40) and 38 (37-39) weeks, and median birth weights (BW) were 3,165 (2,890-3,440) and 3,045 (2,850-3,460) g in the HIE and control groups, respectively. GA, BW, mode of delivery, and gender of infants were similar between the groups. Infants in the HIE group had significantly higher NLR (p = 0.001), SII (p = 0.001), PIV (p = 0.001), and SIRI (p = 0.004) values when compared with the control group. Those indices decreased significantly after hypothermia treatment in the HIE group. Areas under curve for NLR, PLR, MLR, SII, SIRI, and PIV to predict HIE were found to be 0.808, 0.597, 0.653, 0.763, 0.686, and 0.663, respectively. Cutoff values having a good ability to predict HIE for SII and NLR were 410 and 1.12. Elevated NLR level above 1.12 was found to be an independent predictor for HIE, as revealed by multivariate analyses. No associations were found between systemic inflammatory indices and amplitude-integrated electroencephalography (aEEG) patterns, presence of seizures, and death. CONCLUSION: Systemic inflammatory indices may represent reliable and readily available predictors of HIE risk. NLR seems to be an independent factor in diagnosing moderate-to-severe HIE. KEY POINTS: · Systemic inflammatory incides are readily calculated from the peripheral blood count.. · NLR is an independent and valuable factor in diagnosing moderate-to-severe hypoxic-ischemic encephalopathy.. · Systemic inflammatory incides might be feasible for diagnosing hypoxic-ischemic encephalopathy..

Tidal Breathing Parameters Measured by Structured Light Plethysmography in Newborns: Is It Feasible in Neonatal Intensive Care Unit?

OBJECTIVE: Structured light plethysmography (SLP) is a novel and noncontact respiratory assessment technique. It provides tidal breathing measurement in patients difficult to cooperate. In this study, we aimed to determine data for tidal breathing parameters measured by SLP in newborns. STUDY DESIGN: Infants between 2 and 5 days of life without having any respiratory symptoms were eligible for this observational study. In total, 5 minutes of tidal breathing was recorded using SLP (Thora-3Di, PneumaCare Ltd, Cambridge, U.K.) in each infant. Various tidal breathing parameters including timing indices, flow-based parameters, and regional parameters were obtained from SLP data. RESULTS: A total of 57 infants underwent measurements in the study. Evaluable recordings from 42 term and 11 late preterm infants were analyzed. Median gestational age and birthweight of the infants were 38 (37-39) weeks and 3,195 (2,790-3,585) g, respectively. In terms of flow-based parameters, "tidal inspiratory flow at 50% of inspiratory volume divided by tidal expiratory flow at 50% of expiratory volume" was 1.29 (1.13-1.53). Relative contribution of the thorax to each breath in percentage was measured as 38.67 (28.21-43.60). Median values of left-right hemithoracic asynchrony and thoraco-abdominal asynchrony were 6.92 (5.35-9.04) and 17.96 (12.98-36.44) degrees in the study population, respectively. There were no differences in tidal breathing parameters except "hemithoracic asynchrony" between term and late preterm infants. Hemithoracic asynchrony was significantly lower in term neonates than late preterms. CONCLUSION: SLP was found to be feasible to obtain measures of tidal breathing parameters in newborns and it could be performed successfully even in the first days of life.

Lung Lavage with Dilute Surfactant vs. Bolus Surfactant for Meconium Aspiration Syndrome.

OBJECTIVE: To compare the effectiveness of lung lavage with surfactant vs. bolus surfactant treatment in meconium aspiration syndrome (MAS). PATIENTS AND METHODS: This randomized controlled trial included newborns ventilated with MAS. In lavage group (n = 17) 30 ml/kg of diluted porcine surfactant was instilled into the lung. In bolus group (n = 16) porcine surfactant (100 mg/kg) was administered as bolus. Respiratory outcomes and mortality were compared between groups. RESULTS: Duration of respiratory support was found to be similar between lavage and bolus groups (3 vs. 3.5 days, p = 0.36). Death or requirement for extracorporeal membrane oxygenation (ECMO) was 12% vs. 6%; respectively (RR: 2, 95% CI 0.16-24.48; p = 1.0). Duration of oxygen therapy, high-frequency ventilation or inhaled nitric oxide requirement did not differ among the groups. CONCLUSION: Lung lavage did not show any advantage over bolus therapy on duration of respiratory support. The incidence of pneumothorax and surfactant re-administration decreased nonsignificantly in lavage group. CLINICAL TRIAL REGISTRATION: We registered the trial to ClinicalTrials.gov (http://clinicaltrials.gov) under identifier NCT02041546. REGISTRY NAME: Lung Lavage With Dilute Poractant Alfa for Meconium Aspiration Syndrome.

Does Circadian Variation of Mothers Affect Macronutrients of Breast Milk?

Objective To determine the within-day variation of fat, protein, and carbohydrate content of breast milk. Methods The study was conducted at Zekai Tahir Burak Maternity Teaching Hospital between April 2013 and January 2014. We obtained milk samples from lactating mothers of hospitalized infants through hand expression after breast-feeding or pumping three times a day. A mid-infrared human milk analyzer was used for measuring the macronutrient contents of breast milk samples. Results Lactating mothers of 52 infants (30 preterm, 22 term) were recruited to the study. No significant difference was found in protein, fat, and carbohydrate content of milk samples throughout the day. We compared within-day variation of macronutrients of transitional and mature milk, milk samples from the mothers of preterm and term infants, and samples collected by either hand expression or pumping. We did not find a significant difference between the groups. Conclusion Absence of circadian variations in lipid, carbohydrate, and protein content of breast milk in our study may be related to ethnic differences, maternal nutritional status, different milk content measurement technique, and population characteristics.

Storage at -80°C preserves the antioxidant capacity of preterm human milk.

BACKGROUND AND OBJECTIVE: It is essential to establish optimum parameters for maintaining the quality of stored milk until the moment of consumption with minimal deterioration of its properties. The aim of the study was to evaluate total antioxidant capacity (TAC) and total oxidation status (TOS) of fresh and freeze-stored samples (at -80°C) of preterm human milk (HM). METHODS: Samples of colostrum were collected from 98 healthy women within the first 4 days after delivery. The total milk volume collected (6 ml) was divided in two aliquot parts: 3 ml for the fresh analysis which was done immediately after the extraction and 3 ml for storage under freezing conditions at -80°C for three months. The antioxidant status and oxidative stress of the fresh and stored breast milk were assessed via determination of TAC and TOS levels. RESULTS: The mean gestational age and the birth weight of the infants were 31.26 ± 2.93 weeks and 1620 ± 581.91 g; respectively. There were no significant correlations between maternal age, route of delivery and milk oxidative stress. There was no significant difference between the levels of TAC, TOS and the oxidative stress index in fresh and freeze-stored samples of colostrum in preterm HM (p > 0.05). CONCLUSION: Freeze storage of preterm HM at -80°C for three months preserves the antioxidant capacity without changing oxidative status of HM, which could be noteworthy for the preterm infant nutrition.

An unusual cause of refractory persistent pulmonary hypertension of the newborn: anomalous origin of one pulmonary artery.

Persistent pulmonary hypertension of the newborn is a source of considerable mortality and morbidity. Anomalous origin of one pulmonary artery, an uncommon congenital cardiac malformation, is a rare cause of persistent pulmonary hypertension. Here, we report the case of a patient with an anomalous origin of one pulmonary artery from the innominate artery who presented with persistent pulmonary hypertension refractory to treatment.

Antenatal corticosteroid administration is associated with lower risk of severe ROP in preterm twin infants.

INTRODUCTION: Robust evidence revealed the impact of antenatal corticosteroid (ACS) administration on lower mortality and short-term neonatal outcomes in singleton preterm infants. We aimed to investigate the impact of ACS therapy on morbidity and mortality in preterm twin infants. METHODS: We conducted this retrospective single-center study from to the records of twin babies of 24-30 weeks of gestation admitted to the neonatal intensive care unit. The study population was grouped based on the exposure to ACS 1-7 days before birth as received or not. Groups were compared regarding in-hospital mortality and neonatal outcomes. RESULTS: Data from 160 twin infants were analyzed. Of those, 102 (64 %) were administered ACS. The median (IQR) gestational age and birth weight of the whole cohort were 28 (27-29) weeks and 1060 (900-1240) g, respectively. ACS administration was associated with a significant decline in respiratory distress syndrome (RDS), requirement ≥2 doses of surfactant, severe intraventricular hemorrhage (IVH), early-onset sepsis (EOS), and retinopathy of prematurity (ROP) requiring treatment (p < 0.05). Logistic regression analysis revealed that gestational age (OR 0.29 95 % CI 0.14-0.62; p = 0.001), ACS administration (OR 0.14 95 % CI 0.03-0.85; p = 0.032), and time to achieve full enteral feeding (OR 1.16 95 % CI 1.03-1.31; p = 0.019) were independently associated with the risk of severe ROP. CONCLUSION: The reduction in the risk of severe ROP besides RDS, severe IVH, and EOS among preterm twins who received ACS was remarkable in our study similar to the trials conducted in preterm singletons. However, large-scale prospective observational studies are required to reveal the efficacy of ACS in preterm twins.

Do preterm infants with Bronchopulmonary dysplasia have a unique postnatal weight gain pattern?

OBJECTIVES: To investigate the weight gain pattern of preterm infants with bronchopulmonary dysplasia (BPD) during the hospital stay using weekly weight assessment methods. METHODS: This single-center, retrospective, cohort study was carried out in Zekai Tahir Burak Maternal Health Education and Research Hospital between 2014 and 2018. One hundred fifty-one preterm infants <32 weeks of gestation and <1500 g of birth weight with BPD were compared to 251 babies without BPD in terms of weekly weight gain, standard deviation score (SDS), and fall in weight SDS till discharge. RESULTS: Mean body weight was significantly lower in babies with BPD in all weeks except postnatal week (PW) 8. The groups had similar daily weight gain between birth and discharge (p = .78). Infants with BPD had lower weight SDS on postnatal day (PD) 14 and 21, and discharge, however similar on PD 28. The fall in SDS between PW 4 and discharge was significantly higher in the BPD group. Infants with BPD had higher fall in weight SDS between birth and discharge (p = .022). Discharge weight SDS was associated with gestational age and weight SDS on PW 4 in the whole cohort. CONCLUSION: Infants with BPD showed a unique and unsteady pattern of growth compromise during the NICU course, most explicitly in early postnatal life and between PD 28-discharge. Future studies should consider not only the early postnatal life but also the period after four weeks of life till discharge to design an optimal nutrition strategy and decent growth for preterm infants with BPD.

Comparison of different growth curves in the assessment of extrauterine growth restriction in very low birth weight preterm infants.

BACKGROUND: Preterm infants are at risk of extrauterine growth restriction (EUGR) and associated complications in the long term. Growth curves are important in assessing postnatal growth in these infants. The aim of this study was to determine the prevalence of EUGR in preterm infants and the factors associated with EUGR using two different growth curves. METHODS: We retrospectively evaluated 596 preterm infants with birth weight ≤1500 g. Small for gestational age (SGA) was defined as birth weight <10th percentile for gestational age. EUGR was defined as discharge weight z score <-2. All z scores were determined using both the Fenton 2013 and Intergrowth-21st (IG-21) growth curves. RESULTS: The infants' median gestational age was 28 weeks (27-29) and median birth weight was 1080 g (900-1243). The prevalence of SGA was 9.2% with IG-21 curves and 5% with Fenton curves (p < 0.001). The median discharge weight was 2060 g (1860-2363). The prevalence of EUGR was significantly higher with the Fenton curves than with the IG-21 curves (38% vs. 31.7%, p < 0.001). The mean discharge weight z score was -1.82±1.29 with Fenton and -1.44±1.49 with IG-21 curves. In multivariate analysis, significant risk factors for EUGR according to the Fenton curves were SGA (odds ratio [OR]: 19.15, 95% confidence interval [CI]: 4.4-82.59), respiratory distress syndrome (RDS) (OR 1.64, 95% CI 1.12-2.4), late neonatal sepsis (LNS) (OR: 2.27, 95% CI: 1.5-3.44), and >16 days to full enteral feeding (OR: 1.8, 95% CI: 1.22-2.68). Similarly, independent risk factors for EUGR according to the IG-21 curve were SGA (OR: 16.3, 95% CI: 7.23-36.9), RDS (OR: 1.81, 95% CI: 1.16-2.83), LNS (OR: 2.29, 95% CI: 1.43-3.68), and >16 days to full enteral feeding (OR: 2.11, 95% CI: 1.38-3.23). CONCLUSION: The growth curves used for diagnosis may lead to differences in EUGR rates in intensive care units and the factors identified as associated with EUGR. At-risk infants should be evaluated for EUGR and their weight and nutritional support should be monitored carefully. Comparisons of long-term outcomes are needed to assess the suitability of growth curves used for EUGR follow-up.

A Comparison of Slow Infusion Intermittent Feeding versus Gravity Feeding in Preterm Infants: A Randomized Controlled Trial.

BACKGROUND: The transition to full enteral feeding is important for ensuring adequate growth in preterm infants. AIMS: The aim of this study was to investigate the effects of two different intermittent feeding methods on the transition to full enteral feeding in preterm infants. STUDY DESIGN: A prospective, randomized controlled study was conducted in a neonatology and perinatology center. SUBJECTS: Preterm infants with a gestational age between 24 + 0/7 and 31 + 6/7 were included in this study. They were divided into two groups: the SIF (slow infusion feeding) group and the IBF (intermittent bolus feeding) group. In the SIF group, feed volumes were administered over one hour using an infusion pump through an orogastric tube, with feeding occurring every three hours. The IBF group received enteral feeding using a gravity-based technique with a syringe through an orogastric tube, completed within 10 to 30 min. OUTCOME MEASURES: The primary outcome was the achievement of full enteral feeding and the occurrence of feeding intolerance. RESULTS: A total of 103 infants were enrolled in the study (50 in SIF and 53 in IBF). The time to achieve full enteral feeding did not differ significantly between the two groups (p = 0.20). The SIF group had significantly fewer occurrences in which gastric residual volume exceeded 50% (p = 0.01). Moreover, the SIF group had a significantly shorter duration of non-per-oral (NPO) status than the IBF group (p = 0.03). CONCLUSIONS: It is our contention that the use of the SIF method as an alternative feeding method is appropriate for infants with feeding intolerance and those at high risk of feeding intolerance.

A randomized, controlled trial of poractant alfa versus beractant in the treatment of preterm infants with respiratory distress syndrome.

We prospectively evaluated the differences in clinical responses and short-term outcomes in preterm infants with respiratory distress syndrome (RDS) treated with poractant alfa or beractant. Premature infants with RDS were randomized to poractant alfa or beractant treatment between July 2008 and June 2009. Patients were followed until 40 weeks of corrected gestational age or death. The fraction of inspired oxygen (Fio(2)) after surfactant treatment, need for repeat doses, and duration of respiratory support and hospitalization were evaluated between groups. Sixty-one infants received poractant alfa and 65 received beractant. Significantly more patients in the beractant group required ≥2 doses of surfactant compared with the poractant alfa group (31% versus 12%, p = 0.023). Extubation rate within the first 3 days after surfactant administration was higher in the poractant alfa group than in the beractant group (81% versus 55.9%, p = 0.004). Posttreatment Fio(2) requirement in the poractant alfa group was significantly lower than in the beractant group on days 1, 3, and 5. Overall mortality and morbidities were similar between groups. Survival free of bronchopulmonary dysplasia (BPD) at the end of study period was 78.7% and 58.5% in poractant alfa and beractant groups, respectively (p = 0.015). Our study confirms the rapid onset of action, less need for redosing, rapid extubation, and higher survival free of BPD in preterm infants treated with poractant alfa.

Do oral probiotics affect growth and neurodevelopmental outcomes in very low-birth-weight preterm infants?

OBJECTIVE: To evaluate the growth and neurodevelopment outcomes of very low-birth-weight (VLBW) preterm infants supplemented with oral probiotics for the prevention of necrotizing enterocolitis (NEC). STUDY DESIGN: This prospective follow-up study was conducted in a cohort of VLBW preterm infants enrolled in a randomized controlled clinical trial to evaluate the efficacy of oral probiotics for the prevention of NEC. Growth outcomes included weight, length, and head circumference. Cognitive and neuromotor development were assessed by using the Bayley Scales of Infant Development II. Sensory and neurological performance was evaluated by standard techniques. The primary outcome was neurodevelopmental impairment at 18 to 22 months' corrected age. RESULTS: A total of 221 infants completed the trial protocol. Of the 208 infants eligible for follow-up, 174 infants (86 in the probiotics group and 88 in the control group) were evaluated. There was no significant difference in growth and neurodevelopmental outcomes between the two groups. CONCLUSION: Oral probiotic administered to VLBW infants to reduce the incidence and severity of NEC started with the first feed did not affect growth, neuromotor, neurosensory, and cognitive outcomes at 18 to 22 months' corrected age.

Evaluation of Breast Milk Macronutrient Content in Preeclamptic Mothers.

Background: Preeclampsia remains among the leading causes of maternal and perinatal morbidity and mortality worldwide. This study aimed to evaluate the macronutrient content of colostrum in mothers with preeclampsia. Materials and Methods: Women who delivered by cesarean section at ≤37 weeks of gestation were included in the study. Fresh colostrum samples were collected by manual expression on postpartum days 2 and 4 and were analyzed using a mid-infrared human milk analyzer. Demographic characteristics of the patients were recorded. The protein, fat, carbohydrate, and energy composition of the milk samples were compared between mothers with and without preeclampsia. Results: A total of 58 colostrum samples (25 preeclampsia, 33 nonpreeclampsia) were analyzed. The median gestational age of the infants was similar in both groups (32 versus 33 weeks; p > 0.05). There were also no differences between the groups in terms of maternal age, maternal body mass index, maternal weight gain during pregnancy, and infant gender. Median protein, fat, and carbohydrate levels in the colostrum of the preeclamptic mothers were 2.2, 2.1, and 6.3 g/dL, respectively, compared with 1.8, 2.4, and 6.2 g/dL in the nonpreeclamptic mothers, respectively. Although the colostrum of preeclamptic mothers had higher protein content and lower fat content, the difference was not statistically significant. Carbohydrate and energy contents were similar in both groups. Conclusions: The presence of preeclampsia does not cause a significant change in the macronutrient composition of mother's milk. Analyses of micronutrients at different lactation stages in larger samples are needed.

Prolonged minimal enteral nutrition versus early feeding advancements in preterm infants with birth weight ≤1250 g: a prospective randomized trial.

OBJECTIVE: To determine the effect of two different feeding strategies on time to achieve full enteral feeding and the incidence of feeding intolerance in preterm infants with birth weight ≤1250 g. METHODS: A prospective randomized trial (NCT02913677) conducted at a tertiary level neonatal intensive care unit. Preterm infants with birth weight ≤1250 g were randomly allocated to either prolonged minimal enteral nutrition (MEN) in which feed volumes were not increased for five days or early feeding advancement groups in which feed volumes were advanced by 20-25 ml/kg/d until 150 ml/kg/d feed volume was achieved. The primary outcomes were time to reach full enteral feeding sustained for 72 h and incidence of feeding intolerance. RESULTS: A total of 199 infants (99 in prolonged MEN and 100 in early feeding advancement groups) were involved in the study. No statistically significant differences were observed in time to achieve full enteral feeding and feeding intolerance. Daily weight gain (19 versus 16 g; p < .001) was significantly higher in prolonged MEN group. There were no significant differences in weight percentiles and z-scores at discharge. Duration of hospitalization was comparable between the groups. The overall incidence of late onset sepsis and culture proven sepsis was similar in both groups (p = .92 and p = .22, respectively). Incidence of necrotizing enterocolitis (NEC) was 5% in early feeding advancement group, whereas no case of NEC was observed in prolonged MEN group (p = .06). CONCLUSIONS: Prolonged MEN is not associated with a delay in time to achieve full enteral feedings. It may even provide an advantage for development of NEC in extremely low birth weight infants. TRIAL REGISTRATION: Clinical Trials.gov: NCT02913677.

Ventilator-delivered nasal intermittent positive pressure ventilation versus nasal biphasic positive airway pressure following extubation in infants ≤1250 g birth weight: a randomized trial.

BACKGROUND AND OBJECTIVE: To determine the effectiveness of ventilator-delivered nasal intermittent positive pressure ventilation and nasal biphasic positive airway pressure (n-BiPAP) after first extubation attempt in infants ≤1250-g birthweight. METHODS: This randomized controlled study included mechanically ventilated preterm infants of ≤1250-g birthweight who were randomly assigned to ventilator-delivered NIPPV or n-BiPAP at first extubation within 2 weeks of age. The primary outcome (extubation failure within 96 h following extubation) and secondary outcomes were compared. RESULTS: Extubation failure occurred in 22 of 74 infants in n-BiPAP group and 34 of 75 infants in NIPPV group (OR 0.51, 95% CI: 0.26-1.002; p = .05). Duration of invasive and noninvasive ventilation were found to be similar between groups. Also, there were no significant differences among groups for intraventricular hemorrhage, medically/surgically treated patent ductus arteriosus, necrotizing enterocolitis, BPD or death. CONCLUSION: Sustained extubation in infants ≤1250-g birthweight and <2 weeks age did not differ between ventilator-delivered NIPPV and n-BiPAP. TRIAL REGISTRATION: Clinical Trials.gov under identifier NCT02842190.

The Relationship of Adolescent Motherhood to the Macronutrient Content of Breast Milk.

Objective: Breast milk is the best nutrient for newborns due to its rich dietary content, immunological factors, ease of accessibility, and affordability. Given the fact that adolescent birth rate in Turkey is high, this study examines the effects of adolescent motherhood with regard to macronutrient contents in breast milk. Study Design: We collected colostrum samples from mothers staying at our hospital. Gestational ages were ≥37 weeks. Demographic characteristics of the patients were registered. The MIRIS (Mid-Infrared Human Milk Analyzer) device was operated to analyze breast milk, adopting a spectroscopy method for measurements. Protein, fat, carbohydrate, and energy levels of the hindmilk samples were measured; thus, study groups were compared. Results: The study included 224 mothers, of whom 49 were adolescents and 125 were adults. Maternal weight and maternal body mass index, weight gain during pregnancy, mode of delivery and gestational age, as well as birth weight and gender of the infants were similar. As breast milk contents were compared, we found out that fat content levels in the colostrum of adolescent mothers were significantly higher, with respect to the other group. Protein and carbohydrate levels were lower in adolescents, even if they were not statistically significant. There was no difference between the groups in terms of energy levels. Conclusion: Adolescent motherhood may have negative influences on infant welfare. However, in terms of breast milk content quality, adult mothers are not superior to adolescents.

Serum amyloid-A levels in neonatal necrotizing enterocolitis.

We aimed to evaluate serum levels of serum amyloid-A (SAA) both in the diagnosis and monitoring the treatment response of necrotizing enterocolitis (NEC). Forty-five preterm neonates were enrolled in the study, including 15 infants with NEC, 15 with sepsis, and 15 healthy preterm infants. Pre- and posttreatment serum SAA levels were measured. Among patients with NEC, 11 had stage 1 and 4 had stage 2 disease according to the modified Bell's staging criteria. Baseline SAA levels of the infants with NEC were significantly higher than controls (P=0.013) and were significantly lower than those with sepsis (P=0.004). When infants with stage 1 and stage 2 NEC were analyzed separately, baseline SAA levels of the infants with stage 2 NEC were significantly higher than controls (P=0.027) than those with stage 1 NEC (P=0.018), but similar to those with sepsis. There was a trend that baseline SAA levels were also correlated with the Bell stage (r=0.501, P=0.057). Posttreatment SAA levels significantly decreased in infants with sepsis (P=0.002). Pre- and posttreatment SAA levels were similar in patients with stage 1 and 2 NEC. In conclusion, SAA rises in early stages of NEC and may aid in diagnosis as a serum marker.

Comparison of the Macronutrient Content of Colostrum: Locals with Refugees.

Background: Breast milk (BM) is considered the ideal and natural way of feeding for all infants. Although previous studies evaluated the factors influencing the content of BM, data concerning the effect of being a refugee on macronutrient contents of BM are rather inadequate. Therefore, we aimed to compare the macronutrient content of colostrum samples of Turkish and Syrian mothers. Materials and Methods: BM from lactating mothers who delivered term newborns was collected within the first 48 hours of lactation. Milk protein, fat, carbohydrate, and energy levels were measured by using a mid-infrared human milk analyzer. Demographic characteristics of the mothers and the infants were recorded. Results: Colostrum samples of 180 lactating mothers (Turkish: 96, Syrian: 84) were obtained. There were no significant differences between the groups in terms of body mass index of the mothers, mode of delivery, and infant gender. However, Syrian mothers gained less weight during pregnancy compared with Turkish mothers (p = 0.029). The median protein, fat, and energy levels of colostrum samples were found to be significantly higher in Turkish mothers than in Syrian mothers (p = 0.001, p = 0.017, p < 0.001, respectively). Cesarean delivery and being a Syrian refugee were independently associated with lower protein content of colostrum in logistic regression analysis. Conclusion: Lactating mothers who delivered their babies through vaginal route were found to be advantageous in terms of colostral protein content. Also, an association between being a refugee and lower protein content of colostrum was remarkable.
