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.

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.

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

Resumo 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.

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.

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.

Aspectos desconocidos de la relación entre el sistema de grupo sanguíneo ABO y las morbilidades en prematuros / Unknown aspects of the relationship between ABO blood group system and preterm morbidities

Objetivos. Se ha demostrado, en diversos estudios llevados a cabo en adultos, que los grupos sanguíneos desempeñan un papel importante en muchas enfermedades. El objetivo fue investigar si hay una relación entre las morbilidades y el sistema de grupos sanguíneos ABO en lactantes prematuros.Metodología. En este estudio de cohorte retrospectivo, se incluyó a recién nacidos prematuros que habían nacido con menos de 32 semanas de gestación y con un peso al nacer inferior a 1500 g. Se los agrupó por grupo sanguíneo (0, A, B, AB) y por morbilidades de la prematurez y se los comparó.Resultados. Se analizaron los datos de 1785 recién nacidos prematuros de muy bajo peso al nacer. La comparación entre los grupos sanguíneos A y no A reveló que los lactantes de grupo sanguíneo A tenían una incidencia más alta de conducto arterial persistente (CAP) (48,7 % frente a 39,7 %, p = 0,005) y displasia broncopulmonar (DBP) (27 % frente a 20,8 %, p = 0,04), mientras que la incidencia de la hemorragia intraventricular de grado ≥3 era más baja (5,1 % frente a 10,1 %, p = 0,006).Conclusión. Este estudio es la primera y más grande investigación sobre la relación entre los grupos sanguíneos y las morbilidades en los prematuros. Con estos resultados se demuestra que el grupo sanguíneo A podría ser un factor de riesgo de CAP y DBP

Objectives. Blood groups have been shown to play an important role in a lot of diseases in various studies conducted in adults. The objective was to investigate whether there is a relationship between morbidities and ABO blood groups system in preterm infants.Methodology. This retrospective cohort study included preterm neonates born at < 32 weeks of gestation with a birth weight < 1500 g. Neonates were grouped by blood type (O, A, B, AB) and morbidities of prematurity were compared among these groups. Results. Data pertaining to 1785 very low birth weight preterm neonates were analyzed. Comparison of the A and non-A blood groups revealed that infants with blood group A had significantly higher incidence of patent ductus arteriosus (PDA) (48.7 % vs. 39.7 %, p = 0.005) and bronchopulmonary dysplasia (BPD) (27 % vs. 20.8 %, p = 0.04), while the incidence of grade ≥ 3 intraventricular hemorrhage was lower (5.1 % vs. 10.1 %, p = 0.006).Conclusion. This study represents the first and biggest series examination of the relationship between blood groups and preterm morbidities. Our results show that blood group A may be a risk factor for PDA and BPD.

Neonatal jaundice and splenic hematoma.

In the newborn period, unconjugated hyperbilirubinemia (UHB) is common, multifactoral, and associated with a variety of physiologic and pathologic conditions. The most commonly identified pathologic cause leading to hyperbilirubinemia is hemolytic disease of the newborn. We report a five-days-old female infant with neonatal jaundice secondary to splenic hematoma.
