A novel useful marker in the early discrimination of transient hyperthyrotropinemia/hypothyroxinemia and congenital hypothyroidism in preterm infants: thyroid-stimulating hormone/free thyroxine ratio.

OBJECTIVES: Transient hyperthyrotropinemia/transient hypothyroxinaemia and congenital hypothyroidism (CH) have completely different treatment and clinical outcomes. However, a powerful, highly sensitive and cost-effective marker for the differentiation of these clinical entities in the early postnatal period is not available. Therefore, we aimed to test the potential, early predictive, diagnostic power of the thyroid-stimulating hormone (TSH)/free thyroxine (fT4) ratio for differentiation of the two clinical entities in the early period of life. METHODS: TSH and fT4 levels were recorded on the postnatal day 7 of premature infants<32 weeks of gestational age. TSH/fT4 ratio was calculated. The significance degree of TSH/fT4 ratio was analyzed for the differentiation of transient hyperthyrotropinemia or transient hypothyroxinaemia and CH. RESULTS: The study included 1,204 preterm infants<32 weeks of gestational age. Of the 1,204 infants, 978 (81.2 %) had normal thyroid function. Eighty-eight infants (7.3 %) were diagnosed with CH and 138 (11.5 %) with transient hyperthyrotropinemia or transient hypothyroxinemia. Initial TSH/fT4 ratio>4.8 was found to be an early diagnostic warning sign with high power in favor of transient hyperthyrotropinemia or transient hypothyroxinemia (AUC value: 0.947) and TSH/fT4 ratio>12.5 (AUC value: 0.999) was found to be an early diagnostic warning sign with high power in favor of CH (p=0.0001). CONCLUSIONS: We found for the first time that the TSH/fT4 ratio can be used for the early differentiation of transient hyperthyrotropinemia/transient hypothyroxinaemia and CH in preterm infants without additional cost and with high power.

Investigation of the effect of vitamin K1 prophylaxis on newborn screenings tests in newborns.

Background: Routine screening for hereditary disorders in newborns includes screening for treatable metabolic and endocrine disorders, such as biotidinase deficiency, galactosemia, maple syrup urine disease, hypothyroidism, and cystic fibrosis. Incorrect test results may be encountered due to the use of vitamin K1. To investigate the interference effect of vitamin K1 on neonatal screening tests and to raise awareness of erroneous measurements. Methods: Heel blood samples were taken from 25 newborns born in a neonatal intensive care unit. Dry blood C0, C2, C3, C4, C4DC, C5:1, C5OH, C5DC, C6, C6DC, C8, C8:1, C8DC, C10, C10:1, C10DC, C12, C14, C14:1, C14:2, C16, C16:1, C18, C18:1, C18:2, C18:OH, methylglutaryl, valine, leucine/isoleucine, methionine, phenylalanine, argininosuccinic acid, aspartate, alanine, arginine, citrulline, glycine, ornithine, and glutamate tests were studied using the tandem mass spectrometry (MS) method. The results of the heel blood samples obtained before and after the application of vitamin K1 (Phyto menadione) were compared. Results: In two studies conducted with in vitro and in vivo tests, C0, C2, C3, C4, C4DC, C5, C5OH, C6, C8, C10, C10:1, C14, C16, C16:1, C18, C18:1, methylglutaryl, phenylalanine, argininosuccinic acid, tyrosine, aspartate, arginine, citrulline, glycine, and glutamine were all significantly elevated (p < 0.05). Conclusions: Heel blood samples may yield false results due to vitamin K1 administration. In the case of doubtful results, a new sample should be taken and the measurement should be repeated.

Effects of kinesiology taping on swallowing functions in newborns with swallowing difficulties: a randomized controlled pilot study.

OBJECTIVE: This study investigated the efficacy of kinesiology taping application in premature infants with dysphagia. METHODS: A total of 60 premature newborns (born ≤37weeks' gestational age who reached the age ≥34 weeks of postmenstrual age) with sucking and swallowing problems were randomly assigned to the kinesiology taping group [n=31; 18 males, 13 females; mean postmenstrual age 35.4 weeks (SD 0.9 weeks, range 34-38 weeks)] or control group without kinesiology taping application [n=29; 16 males, 13 females; mean postmenstrual age age 35.6 weeks (SD 1.4 weeks, range 34-40 weeks)]. RESULTS: Kinesiology taping group yielded significant improvement in the oral reflexes (p<0.001) and in the sucking functions including tongue movement, sucking power, number of sucks and sucking pause, maintenance of alertness, jaw movement, tongue cupping, and maintenance of rhythm (p<0.001, p=0.011, p=0.002, and p=0.001, respectively). There was a significant difference in favor of the taping group with respect to the number of neonates whose feeding improved (26 (84%) vs. 7 (24%), p<0.001). CONCLUSION: The results of this study show that kinesiology taping can be applied as a safe and effective method to improve feeding functions in premature infants with sucking and swallowing difficulties.

Antenatal Neuroprotective Magnesium Sulfate in Very Preterm Infants and Its Association With Feeding Intolerance.

INTRODUCTION/OBJECTIVE: Magnesium sulfate (MgSO 4 ) treatment is widely used for fetal neuroprotection despite the controversy concerning the side effects. There is limited data regarding the impact of various cumulative maternal doses and neonatal serum magnesium (Mg) levels on short-term neonatal morbidity and mortality. We opted to carry out a study to determine the impact of neonatal serum Mg levels on neonatal outcomes. METHOD: We conducted this prospective observational study between 2017 and 2021. Antenatal MgSO 4 was used for neuroprotective purpose only during the study period. Inborn preterm infants delivered between 23 and 31 6/7 weeks of gestation were enrolled consecutively. Babies who underwent advanced resuscitation in the delivery room, inotropic treatment due to hemodynamic instability in the first 7 days of life, >12 hours since the discontinuation of maternal MgSO 4 treatment, severe anemia, and major congenital/chromosomal anomalies were excluded from the study. The subgroup of babies with serum Mg level at the 6th hour of life underwent an analysis. A neonatal Mg concentration of 2.5 mg/dL was used to classify MgSO 4 -exposed patients into 2 groups (<2.5 mg/dL and ≥2.5 mg/dL). Another analysis was performed between babies whose mothers were exposed to MgSO 4 and those not exposed. Finally, the groups' neonatal outcomes were compared. RESULTS: Of the 584 babies, 310 received antenatal MgSO 4 . The birth weights were significantly lower in the MgSO 4 exposed group (1113 ± 361 g vs 1202 ± 388 g, P = 0.005). Antenatal corticosteroid usage and intrauterine growth restriction were also noted to be higher. The MgSO 4 group was more likely to have bronchopulmonary dysplasia, prolonged invasive ventilation, necrotizing enterocolitis, delayed enteral nutrition, and feeding intolerance ( P < 0.05). MgSO 4 treatment was shown as an independent risk factor for feeding intolerance when corrected for confounders (odds ratio 2.13, 95% confidence interval: 1.4-3.1, P = 0.001). Furthermore, serum Mg level significantly correlated with feeding intolerance ( r = 0.21, P = 0.002). CONCLUSION: This study highlighted the effect of MgSO 4 treatment and the potential superiority of serum Mg level as a predictor of immediate neonatal outcomes, particularly delayed enteral nutrition and feeding intolerance. Further studies are warranted to ascertain the optimal serum Mg concentration of preterm infants in early life to provide maximum benefit with minimal side effects.

Evaluation of the efficacy of systemic inflammatory indices in determining mortality in very low birth weight infants.

OBJECTIVE: In our study, we aimed to investigate whether systemic inflammatory indices could be an indicator of mortality in very low birth weight (<1,500 g) preterm infants. METHODS: Very low birth weight preterm infants were included in our study, and patient data were recorded retrospectively. Neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, monocyte-to-lymphocyte ratio, systemic immune-inflammation index, pan-immune-inflammation value, and systemic inflammation response index were calculated and recorded. The survivors and infants who died were compared for systemic inflammatory indices. RESULTS: A total of 1,243 very low birth weight infants were included in the study. Of the patients, 1,034 survived and 209 died. Neutrophil-to-lymphocyte ratio, monocyte-to-lymphocyte ratio, platelet-to-lymphocyte ratio, pan-immune-inflammation value, systemic immune-inflammation index, and systemic inflammation response index were found to be statistically significantly lower in the mortality group than those in the survivor group (p=0.039, p=0.001, p<0.001, p<0.001, p<0.001, and p=0.002, respectively). According to the receiver operating curve analysis, systemic immune-inflammation index with the highest area under the curve (0.844) was found to be the most effective systemic inflammatory indices in predicting mortality with a cutoff level of ≤28.87 (p=0.0001). Multiple regression analysis showed that a lower level of systemic immune-inflammation index (≤28.87) was independently associated with mortality (OR: 1.677, 95%CI 1.061-2.685, p=0.001). CONCLUSION: We have shown that low systemic immune-inflammation index value in very low birth weight preterm infants may be a novel systemic inflammatory index that can be used to predict mortality.

Serum ADAMTS-9 Level in Newborn Babies with Congenital Heart Disease.

OBJECTIVE: A Disintegrin and Metalloproteinase with Thrombospondin-9 (ADAMTS-9), one of the ADAMTS enzymes, is expressed in all fetal tissues, unlike other ADAMTS enzymes, and is thus thought to play a role in fetal development. In this context, the objective of this study is to investigate the relationship between ADAMTS-9 activity and the development of congenital heart diseases (CHD) with a view to using ADAMTS-9 level as a biomarker for CHDs. STUDY DESIGN: Newborns diagnosed with CHD and healthy newborns were included in the study as the CHD and control groups, respectively. Gestational age, maternal age, and mode of delivery information pertaining to the mothers and Apgar score and birthweight information pertaining to the newborns were recorded. Blood samples were taken from all newborns to determine their ADAMTS-9 levels in the first 24 hours of life. RESULTS: Fifty-eight newborns with CHD and 46 healthy newborns were included in the study. Median ADAMTS-9 levels were 46.57 (interquartile range [IQR]: 33.31 [min: 26.92, max: 124.25]) and 23.36 (IQR: 5.48 [min: 11.7, max: 37.71]) ng/mL in the CHD and control groups, respectively. ADAMTS-9 levels in the CHD group were statistically significantly higher than in the control group (p = 0.000). ADAMTS-9 levels of the CHD and control groups were analyzed by the receiver operating characteristics curve. The area under the curve value for ADAMTS-9 levels of >27.86 ng/mL as the cut-off value for predicting the development of CHD in newborns was 0.836 (95% confidence interval [CI]: 0.753-0.900, p = 0.0001). ADAMTS-9 levels of >27.86 ng/mL were determined to predict the development of CHD in newborns with a sensitivity of 77.78% (95% CI: 65.5-87.38) and a specificity of 84.78% (95% CI: 71.1-93.60). CONCLUSION: In conclusion, it was found that the serum ADAMTS-9 levels were significantly higher in newborns with CHD than in healthy newborns. In parallel, ADAMTS-9 levels above a certain cut-off value were associated with CHD. KEY POINTS: · ADAMTS-9 is expressed in fetal tissues.. · Its level increases in congenital heart diseases.. · It can be used as a biochemical marker in diagnosis..

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.

Role of Systemic Inflammatory Indices in the Prediction of Moderate to Severe Bronchopulmonary Dysplasia in Preterm Infants

Introduction: The role of systemic inflammatory indices in the diagnosis of bronchopulmonary dysplasia (BPD) is unknown. The aim of the study was to determine the possible clinical utility of systemic inflammatory indices in the prediction of moderate to severe BPD. Methods: Premature infants<32 weeks of gestational age were included in the study. Neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), monocyte-to-lymphocyte ratio (MLR), systemic immune-inflammation index (SII), pan-immune-inflammation value (PIV), and systemic inflammation response index (SIRI) were calculated at birth and at the time of diagnosis of BPD (at 36th weeks of postmenstrual age). The patients were divided into two groups as no or mild BPD and moderate or severe BPD. Results: A total of 1146 infants were included in the study, 957 in Group 1 and 189 in Group 2. The SIRI value was significantly higher in moderate or severe BPD both at birth and at the 36th week of postmenstrual age (p<0.001 and p<0.001, respectively). The AUC value of SIRI was 0.809 and the cut-off value was>0.98 in the predictivity of BPD at birth. The AUC value of SIRI was 0.842 and the cut-off value was>1.33 for the diagnosis of BPD at 36th week of postmenstrual age. After multiple logistic regression analysis, SIRI was shown to be a significant parameter for the diagnosis of BPD (OR 2.847, 95% CI 1.557–4.875). Conclusions: SIRI may be a useful biomarker for predicting moderate to severe BPD and a marker of clinical importance in the follow-up of infants with BPD. (AU)

Hemoglobin/Red Cell Distribution width Ratio (HRR): A Novel and Promising Red Cell Parameter in Ductal Closure. / Proporção de Largura de Distribuição de Hemoglobina/Glóbulos Vermelhos (HRR): Um Novo e Promissor Parâmetro de Glóbulos Vermelhos no Fechamento Ductal.

BACKGROUND: It is still unclear how effective hematological parameters are in the closure of patent ductus arteriosus (PDA). OBJECTIVES: The primary aim of our study is to investigate the effect of hemoglobin (HB)-to-red cell distribution width (RDW) ratio (HRR) on the closure of PDA. METHODS: Premature babies with very low birth weight (VLBW: <1500 g) and <32 gestational weeks were included in the study, and all data were recorded retrospectively. Demographic characteristics, clinical results, red cell parameters, and HRR and their ratios were compared between hemodynamically significant PDA (hsPDA) and non-hsPDA groups. All results were statically analyzed, and P<0.05 was considered statistically significant. RESULTS: A total of 677 premature babies, 269 in the hsPDA group and 408 in the non-hsPDA group, were included in the study. Hemoglobin (HB), hematocrit (HCT), mean cell volume (MCV), red blood cell (RBC), red cell distribution width (RDW), mean platelet volume (MPV), MCV/RBC ratio, HB/RBC ratio, RDW/RBC ratio, and RDW/MPV ratio were found to be similar between hsPDA and non-hsPDA groups, (p>0.05). HRR was found to be significantly lower in the hsPDA group [median (Quartile 1 (Q1) - Q3) (Q1 - Q3): 0.93 (0.8-1.0)] compared to non-hsPDA [median ( Q1 - Q3): 1.07 (1.0-1.2)] (p<0.001). The AUC for the diagnostic value of HRR in hsPDA was 0.816, and the cutoff value was ≤0.98 (p<0.001, 95% [CI]: 0.785-0.845, sensitivity: 90%, specificity: 92%). CONCLUSIONS: HRR value was found to be both an effective and powerful parameter in diagnosing hsPDA.

FUNDAMENTO: Ainda não está clara a eficácia dos parâmetros hematológicos no fechamento da persistência do canal arterial (PCA). OBJETIVOS: O objetivo principal do nosso estudo é investigar o efeito da proporção (HRR) de largura de distribuição de hemoglobina (HB) para glóbulos vermelhos (RDW) no fechamento do PCA. MÉTODOS: Bebês prematuros com muito baixo peso ao nascer (MBPN: <1.500 g) e <32 semanas gestacionais foram incluídos no estudo, e todos os dados foram registrados retrospectivamente. Características demográficas, resultados clínicos, parâmetros de hemácias e HRR e suas proporções foram comparados entre grupos de PCA hemodinamicamente significativa (hsPDA) e não-hsPDA. Todos os resultados foram analisados estatisticamente, e p<0,05 foi considerado estatisticamente significativo. RESULTADOS: Um total de 677 bebês prematuros, 269 no grupo hsPDA e 408 no grupo não-hsPDA, foram incluídos no estudo. Hemoglobina (HB), hematócrito (HCT), volume celular médio (VCM), glóbulos vermelhos (RBC), largura de distribuição dos glóbulos vermelhos (RDW), volume plaquetário médio (VPM), relação VCM/RBC, relação HB/RBC, RDW A razão /RBC e a razão RDW/VPM foram semelhantes entre os grupos hsPDA e não hsPDA, (p>0,05). HRR foi significativamente menor no grupo hsPDA [mediana (Quartil 1 (Q1) - Q3) (Q1 - Q3): 0,93 (0,8-1,0)] em comparação com não-hsPDA [mediana (Q1 - Q3): 1,07 ( 1,0-1,2)] (p<0,001). A AUC para o valor diagnóstico de HRR em hsPDA foi de 0,816 e o valor de corte foi ≤0,98 (p<0,001, 95% [IC]: 0,785-0,845, sensibilidade: 90%, especificidade: 92%). CONCLUSÕES: O valor de HRR foi considerado um parâmetro eficaz e poderoso no diagnóstico de hsPDA.

Evaluation of the Effectiveness of Systemic Inflammatory Indices in the Diagnosis of Respiratory Distress Syndrome in Preterm with Gestational Age of ≤32 Weeks.

OBJECTIVE: It is not yet known whether systemic inflammatory indices affect the development of respiratory distress syndrome (RDS) in premature infants. We aimed to evaluate the relationship between systemic inflammatory indices obtained on the first day of life and the development of RDS in premature infants. STUDY DESIGN: Premature infants with gestational age of ≤32 weeks were included in the study. Six systemic inflammatory indices involving neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), monocyte-to-lymphocyte ratio (MLR), systemic immune-inflammation index (SII), pan-immune-inflammation value (PIV), and systemic inflammation response index (SIRI) were measured in the first 1 hour after birth and compared in premature infants with and without RDS. RESULTS: A total of 931 premature infants, 579 infants in the RDS group and 352 infants in the non-RDS group, were included in the study. MLR, PLR, and SIRI values were similar between the groups (p > 0.05 for all parameters). NLR, PIV, and SII values in the RDS group were significantly higher than those in the non-RDS group (p = 0.005, p = 0.011, and p < 0.001, respectively). In the predictivity of RDS, the AUC value of SII was 0.842 and the cut-off value was ≥78.200. Multiple logistic analysis showed that a higher level of SII (≥78.2) was independently associated with RDS (odds ratio: 3.03, 95% confidence interval: 1.761-5.301). CONCLUSION: Our results demonstrated that a higher SII level (≥78.2) may be a predictor for the development of RDS in premature infants with gestational age of ≤32 weeks. KEY POINTS: · It is not yet known whether systemic inflammatory indices affect the development of RDS.. · Our results demonstrated high SII levels may be a predictor for the development of RDS.. · SII may provide an advantage as a low-cost, easy-to-detect, useful and powerful parameter in RDS..

Phototherapy-induced hypocalcemia and hypoparathyroidism in icteric term newborns.

OBJECTIVES: Phototherapy is demonstrated to cause hypocalcemia by decreasing melatonin levels and increasing cortisol levels. However, the relationship between parathyroid hormone (PTH) level and calcium has not been previously evaluated in patients receiving phototherapy. Our study aimed to evaluate the effect of phototherapy on ionized calcium (iCa), total calcium (tCa), corrected calcium (cCa), magnesium (Mg), phosphorus (P), 25-hydroxyvitamin D (25(OH)D), and PTH levels. METHODS: Infants who were born at term and received inpatient phototherapy for indirect hyperbilirubinemia were included in our study. The patients' gestational age, birth weight, and phototherapy durations were recorded. Total bilirubin, albumin, iCa, tCa, cCa, Mg, 25(OH)D, and PTH levels before and after phototherapy were compared. Laboratory results were also compared between patients who received phototherapy for ≤24 h, 25-47 h, and ≥48 h. RESULTS: A total of 166 term infants were included in the study. The mean duration of phototherapy was 31.9 ± 9.2 h. Albumin levels before and after phototherapy were similar (p=0.246). However, there were significant decreases in iCa, tCa, cCa, Mg, 25(OH)D, and PTH levels after phototherapy (p<0.001), while P level was significantly increased after phototherapy (p<0.001). In addition, P levels increased with >24 h of phototherapy, while iCa, tCa, cCa, Mg, 25(OH)D, and PTH levels decreased significantly with ≥48 h of phototherapy (p=0.002, p=0.008, p=0.001, p=0.012, and p<0.001, respectively). CONCLUSIONS: This study demonstrates that PTH suppression is one of the causes of phototherapy-induced hypocalcemia.

Maternal Serum and Fetal Cord Blood Concentrations of Thiol/ Disulfide and Ischemia-Modified Albumin as Predictors of Neural Tube Defects.

AIM: To investigate the predictive role of thiol/ disulfide homeostasis and Ischemia-modified albumin (IMA) levels for NTDs. MATERIAL AND METHODS: A total of 71 pregnant women (31 with NTD and 42 healthy controls) were enrolled in this study. This prospective case-control study included pregnant women with NTDs as the study group and randomly selected age-matched pregnant women with healthy fetuses as the control group. The two groups were compared on the basis of thiol/disulfide and IMA levels in the maternal and fetal samples. RESULTS: No statistically significant difference in native thiol, total thiol, disulfide, and calculated ratios was observed between the groups. However, maternal IMA values were significantly higher in the study group. The IMA was proven to be a predictor with a sensitivity of 77.4% and specificity of 100% for NTDs at a cut-off value of 1.32. CONCLUSION: The examination of the maternal levels of IMA may be useful in the detection of NTDs.

Effects of kinesiology taping on swallowing functions in newborns with swallowing difficulties: a randomized controlled pilot study

SUMMARY OBJECTIVE: This study investigated the efficacy of kinesiology taping application in premature infants with dysphagia. METHODS: A total of 60 premature newborns (born ≤37weeks' gestational age who reached the age ≥34 weeks of postmenstrual age) with sucking and swallowing problems were randomly assigned to the kinesiology taping group [n=31; 18 males, 13 females; mean postmenstrual age 35.4 weeks (SD 0.9 weeks, range 34-38 weeks)] or control group without kinesiology taping application [n=29; 16 males, 13 females; mean postmenstrual age age 35.6 weeks (SD 1.4 weeks, range 34-40 weeks)]. RESULTS: Kinesiology taping group yielded significant improvement in the oral reflexes (p<0.001) and in the sucking functions including tongue movement, sucking power, number of sucks and sucking pause, maintenance of alertness, jaw movement, tongue cupping, and maintenance of rhythm (p<0.001, p=0.011, p=0.002, and p=0.001, respectively). There was a significant difference in favor of the taping group with respect to the number of neonates whose feeding improved (26 (84%) vs. 7 (24%), p<0.001). CONCLUSION: The results of this study show that kinesiology taping can be applied as a safe and effective method to improve feeding functions in premature infants with sucking and swallowing difficulties.

Evaluation of the efficacy of systemic inflammatory indices in determining mortality in very low birth weight infants

SUMMARY OBJECTIVE: In our study, we aimed to investigate whether systemic inflammatory indices could be an indicator of mortality in very low birth weight (<1,500 g) preterm infants. METHODS: Very low birth weight preterm infants were included in our study, and patient data were recorded retrospectively. Neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, monocyte-to-lymphocyte ratio, systemic immune-inflammation index, pan-immune-inflammation value, and systemic inflammation response index were calculated and recorded. The survivors and infants who died were compared for systemic inflammatory indices. RESULTS: A total of 1,243 very low birth weight infants were included in the study. Of the patients, 1,034 survived and 209 died. Neutrophil-to-lymphocyte ratio, monocyte-to-lymphocyte ratio, platelet-to-lymphocyte ratio, pan-immune-inflammation value, systemic immune-inflammation index, and systemic inflammation response index were found to be statistically significantly lower in the mortality group than those in the survivor group (p=0.039, p=0.001, p<0.001, p<0.001, p<0.001, and p=0.002, respectively). According to the receiver operating curve analysis, systemic immune-inflammation index with the highest area under the curve (0.844) was found to be the most effective systemic inflammatory indices in predicting mortality with a cutoff level of ≤28.87 (p=0.0001). Multiple regression analysis showed that a lower level of systemic immune-inflammation index (≤28.87) was independently associated with mortality (OR: 1.677, 95%CI 1.061-2.685, p=0.001). CONCLUSION: We have shown that low systemic immune-inflammation index value in very low birth weight preterm infants may be a novel systemic inflammatory index that can be used to predict mortality.

A AUC para o valor diagnóstico de HRR em hsPDA foi de 0,816 e o valor de corte foi ≤0,98 (p<0,001, 95% [IC]: 0,785-0,845, sensibilidade: 90%, especificidade: 92%). Conclusões O valor de HRR foi considerado um parâmetro eficaz e poderoso no diagnóstico de hsPDA.

Abstract Background It is still unclear how effective hematological parameters are in the closure of patent ductus arteriosus (PDA). Objectives The primary aim of our study is to investigate the effect of hemoglobin (HB)-to-red cell distribution width (RDW) ratio (HRR) on the closure of PDA. Methods Premature babies with very low birth weight (VLBW: <1500 g) and <32 gestational weeks were included in the study, and all data were recorded retrospectively. Demographic characteristics, clinical results, red cell parameters, and HRR and their ratios were compared between hemodynamically significant PDA (hsPDA) and non-hsPDA groups. All results were statically analyzed, and P<0.05 was considered statistically significant. Results A total of 677 premature babies, 269 in the hsPDA group and 408 in the non-hsPDA group, were included in the study. Hemoglobin (HB), hematocrit (HCT), mean cell volume (MCV), red blood cell (RBC), red cell distribution width (RDW), mean platelet volume (MPV), MCV/RBC ratio, HB/RBC ratio, RDW/RBC ratio, and RDW/MPV ratio were found to be similar between hsPDA and non-hsPDA groups, (p>0.05). HRR was found to be significantly lower in the hsPDA group [median (Quartile 1 (Q1) - Q3) (Q1 - Q3): 0.93 (0.8-1.0)] compared to non-hsPDA [median ( Q1 - Q3): 1.07 (1.0-1.2)] (p<0.001). The AUC for the diagnostic value of HRR in hsPDA was 0.816, and the cutoff value was ≤0.98 (p<0.001, 95% [CI]: 0.785-0.845, sensitivity: 90%, specificity: 92%). Conclusions HRR value was found to be both an effective and powerful parameter in diagnosing hsPDA.

Analysis of fresh frozen plasma utilization indications in children: An audit of a tertiary care hospital in Turkey.

BACKGROUND: Although indications of fresh frozen plasma (FFP) usage are limited to certain circumstances in children, there is an increasing trend towards inappropriate usage are reported in clinical practice. The aim of this study was to evaluate the appropriateness of pediatric FFP utilization in our tertiary care hospital. METHODS: This prospective observational study was conducted at a tertiary care academic pediatric hospital. All FFP orders were evaluated for appropriateness over a 4-monts period by 2 hematologists. Data collected include demographic information, diagnosis, FFP transfusion indication, pre-transfusion coagulation tests, surgical procedure or bleeding status, and transfusion reactions. RESULTS: Three hundred twenty-four patients (57 % males, 43 % females) were transfused in 987 episodes. The mean age of the patients was 5.4±5.7 years. The majority of the patients (33 %) were under 1 y of age and the products were primarily utilized by pediatric and cardiovascular intensive care units. Pre-transfusion coagulation testing was only available in 674 (68 %) of the transfusion episodes. The rate of appropriate FFP transfusion episodes was 59 % (587/987). Inappropriate usage was mostly related to sepsis and minor coagulation abnormalities without bleeding. The higher rates of inappropriate transfusion orders were observed in pediatric and neonatal intensive care units, and hematology/oncology departments. CONCLUSIONS: Inappropriate use of FFP in children remains a significant challenge. The regular audit and sustainable education programs targeting the efficient use of FFP for health professionals at the national level can improve transfusion practices.

Qual Deve Ser o Tratamento de Primeira Linha para o Fechamento de Persistência de Canal Arterial Hemodinamicamente Significativo em Bebês Prematuros? / What Should be the First-line Treatment for the Closure of Hemodynamically Significant Patent Ductus Arteriosus in Premature Infants?

Resumo Fundamento É importante saber qual medicamento usar como tratamento de primeira linha para fechar o duto. Objetivos O objetivo deste estudo é comparar a eficácia e os efeitos colaterais das formas intravenosas (IV) de ibuprofeno e paracetamol e contribuir para a literatura investigando o primeiro medicamento selecionado no tratamento clínico da persistência do canal arterial (PCA). Métodos Nosso estudo foi realizado entre janeiro de 2017 e dezembro de 2019. Foram incluídos no estudo bebês prematuros com peso ao nascer (PN) ≤1500 g e idade gestacional (IG) ≤32 semanas. No período do estudo, todos os bebês com persistência do canal arterial hemodinamicamente significativa (hsPCA) receberam ibuprofeno intravenoso (IV) como resgate como tratamento clínico primário ou tratamento com paracetamol IV se houvesse contraindicações para o ibuprofeno. Os pacientes foram divididos em dois grupos: pacientes que receberam ibuprofeno IV e pacientes que receberam paracetamol IV. Resultados Desses pacientes, 101 receberam paracetamol IV e 169 receberam ibuprofeno IV. A taxa de sucesso do fechamento da PCA com o primeiro curso do tratamento foi de 74,3% no grupo de paracetamol IV e 72,8% no grupo de ibuprofeno IV (p=0,212). Conclusões Nossos resultados mostram que o paracetamol IV é tão eficaz quanto o ibuprofeno IV no tratamento de primeira linha de hsPCA, podendo se tornar o tratamento preferencial para o controle de hsPCA.

Abstract Background It is important which medicine to use as a first-line treatment to close the duct. Objectives The aim of this study is to compare the effectiveness and side effects of intravenous (IV) forms of ibuprofen and paracetamol and to contribute to the literature investigating the first drug selected in the medical treatment of patent ductus arteriosus (PDA). Methods Our study was conducted between January 2017 and December 2019. Premature infants with birth weight (BW) ≤1500 g and gestational age (GA) ≤32 weeks were included in the study. In the study period, all infants with hemodynamically significant patent ductus arteriosus (hsPDA) were given rescue intravenous (IV) ibuprofen as a primary medical treatment or IV paracetamol treatment if there were contraindications for ibuprofen. The patients were divided into two groups: patients receiving IV ibuprofen and patients receiving IV paracetamol. Results Of these patients, 101 were given IV paracetamol and 169 were given IV ibuprofen. The success rate of PDA closure with first-course treatment was 74.3% in the IV paracetamol group and 72.8% in the IV ibuprofen group (p=0.212). Conclusions Our results show that IV paracetamol is as effective as IV ibuprofen in the first-line treatment of hsPDA, and can become the preferred treatment for the management of hsPDA.

Two Useful Umbilical Biomarkers for Therapeutic Hypothermia Decision in Patients with Hypoxic Ischemic Encephalopathy with Perinatal Asphyxia: Netrin-1 and Neuron Specific Enolase.

Hypoxic-ischemic encephalopathy (HIE) has a high risk of mortality in addition to serious neurological damage. In this study, we investigated the values of umbilical cord netrin-1 (NT-1) and neuron specific enolase (NSE) levels in the early diagnosis of HIE stage II/III induced by neonatal asphyxia.In the study group, infants with gestational age ≥ 36 weeks who were diagnosed with HIE II/III were included. NT-1 and NSE levels were measured from the umbilical cord immediately after birth. Results were compared between HIE II/III and the healthy control group. Cutoff values for serum NT-1 and NSE were determined with receiver-operating characteristics curves and the area under the curve (AUC) was used to determine the diagnostic value of NT-1 and NSE levels in infants diagnosed with HIE II/III.NT-1 (358.3 ± 108.3 pg/mL) and NSE (52.97 ± 17.8 ng/mL) levels in the cord blood in the HIE group were significantly higher (p = .030, p = .001, respectively) than cord blood values in the control group (NT-1 (275.1 ± 84.6 pg/mL) and NSE (28.7 ± 16.3 ng/mL)). NT-1 cutoff value for HIE was 292.3 pg/mL and 34.7 ng/mL for NSE (AUC: 990, sensitivity: 94%, specificity 100% and AUC: 1.0, sensitivity: 100% vs. specificity 100%, respectively).NT-1 and NSE represent candidate biomarkers with high reliability in the prediction in newborns with moderate-to-severe HIE.
