Prevalencia de sepsis neonatal confirmada microbiológicamente en una maternidad de la Ciudad Autó noma de Buenos Aires / Prevalence of microbiologically confirmed neonatal sepsis at a maternity center in the City of Buenos Aires

Introducción. En neonatos internados es frecuente sospechar sepsis neonatal, pero solo en el 25 % al 30 % se confirma con cultivos positivos. La selección del esquema antibiótico basándose en la epidemiología local favorece el uso racional y minimiza sus efectos colaterales. Objetivo primario. Describir la prevalencia de sepsis precoz y tardía con rescate microbiológico y sus características clínicas. Población y método. Estudio transversal retrospectivo, realizado del 1 de enero de 2013 al 31 de diciembre de 2017, en una maternidad pública de Argentina, que incluyó todos los recién nacidos internados en la unidad con diagnóstico de sepsis precoz y tardía con rescate microbiológico, y aquellos reingresados dentro del mes de vida. Resultados. Ingresaron 3322 recién nacidos, 1296 evaluados por sospecha de sepsis precoz, cultivos positivos en 25 (1,9 %; tasa: 0,86 ‰). El 52 % eran menores de 33 semanas de edad gestacional. Microorganismos: Escherichia coli 5, Listeria monocytogenes 4, Streptococcus agalactiae (SGB) 3, Streptococcus pneumoniae 3. Sepsis tardía (tasa 8,73 ‰), el 68 % ocurridas en menores de 33 semanas. Microorganismos intrahospitalarios: Staphylococcus coagulasa negativos 115, Staphylococcus aureus 47, Escherichia coli 30, Cándida spp. 16, Enterococcus faecalis 13, Klebsiella pneumoniae 11 y Streptococcus agalactiae 10. En los reingresos: E. coli 11, S. aureus 12, SGB 3 y Haemophilus influenzae 3. Conclusiones. Se observa en el período estudiado una frecuencia de sepsis precoz similar a los reportes internacionales, con predominio de E. coli y L. monocytogenes. La tasa de sepsis tardía presentó una tendencia descendente en los años analizados, con predominio de los cocos grampositivos

Introduction. Neonatal sepsis is often suspected in hospitalized newborn infants, but only in 25­30% of cases it is confirmed via a positive culture. Selecting the antibiotics based on local epidemiology favors their rational use and minimizes their side effects. Primary objective. To describe the prevalence of early- and late-onset sepsis with microorganism isolation and their clinical characteristics. Population and method. Retrospective, cross-sectional study conducted between 01-01-2013 and 12-31-2017 in a public maternity center of Argentina in all hospitalized newborn infants with a diagnosis of early- and late-onset sepsis with microorganism isolation, and those re-admitted in their first month of life. Results. A total of 3322 newborn infants were admitted; 1296 were assessed for suspected early- onset sepsis; 25 had a positive culture (1.9%; rate: 0.86‰). Of these, 52% were born before 33 weeks of gestation. Microorganisms: Escherichia coli 5, Listeria monocytogenes 4, Streptococcus agalactiae (SGB) 3, Streptococcus pneumoniae 3. Also, 68% of late-onset sepsis cases (rate: 8.73‰) occurred in infants born before 33 weeks of gestation. Hospital-acquired microorganisms: coagulase-negative Staphylococcus 115, Staphylococcus aureus 47, Escherichia coli 30, Candida spp. 16, Enterococcus faecalis 13, Klebsiella pneumoniae 11, and Streptococcus agalactiae 10. In re-admissions: E. coli 11, S. aureus 12, SGB 3, and Haemophilus influenzae 3. Conclusions. During the study period, the frequency of early-onset sepsis was similar to international reports, with a predominance of E. coli and L. monocytogenes. The rate of late-onset sepsis showed a downward trend in the analyzed years, with a predominance of Gram-positive cocci.

Infección osteoarticular multifocal en un recién nacido / Multifocal osteoarticular infection in a neonate / Infecção osteoarticular multi-focal num recém-nascido

Tanto la osteomielitis como la osteoartritis séptica en el período neonatal son patologías infrecuentes. La afectación ósea de la columna cervical es aún más rara, siendo excepcional en neonatos. Son patologías graves, con elevada morbimortalidad, donde el diagnóstico y tratamiento precoz agresivo son de suma importancia para el pronóstico vital y funcional. Presentamos el caso de un neonato que presentó una sepsis a S. Aureus multirresistente, asociada a una osteomielitis de la primera vértebra cervical y a una osteoartritis séptica de la cadera izquierda. Fue tratado precozmente de forma quirúrgica y con antibioticoterapia, presentando una buena evolución.

Both osteomyelitis and septic osteoarthritis in the neonatal period are infrequent pathologies. Bone involvement of the cervical spine is even rarer, being exceptional in neonates. These are serious pathologies, with high morbimortality, where early diagnosis and aggressive treatment are of utmost importance for the vital and functional prognosis. We present the case of a neonate who presented with sepsis due to multidrug-resistant S. Aureus, associated with osteomyelitis of the first cervical vertebra and septic osteoarthritis of the left hip. He was treated early surgically and with antibiotic therapy, presenting a good evolution

Tanto a osteomielite como a osteoartrose séptica no período neonatal são patologias raras. O envolvimento ósseo da coluna cervical é ainda mais raro, sendo excepcional nos recém-nascidos. Estas são patologias graves, com elevada morbimortalidade, onde o diagnóstico precoce e o tratamento agressivo são da maior importância para o prognóstico vital e funcional. Apresentamos o caso de um recém-nascido que apresentou sepse devido a S. Aureus multirresistente, associado a osteomielite da primeira vértebra cervical e osteoartrose séptica da anca esquerda. Foi tratado precocemente cirurgicamente e com terapia antibiótica, com uma boa evolução.

The use of absolute neutrophil count and neutrophil-lymphocyte ratio as predictors of early onset neonatal sepsis

Background@#Neonatal sepsis contributes to significant morbidity and mortality. Blood culture, the gold standard in its diagnosis, has low sensitivity and is affected by multiple factors. Hence the need for markers derived from routine tests to improve diagnosis deserves further studies.@*Objectives@#This study aims to determine the association and optimal cut-off value and diagnostic performance of absolute neutrophil count (ANC) and neutrophil lymphocyte ratio (NLR) with early-onset neonatal sepsis in term neonates.@*Methodology@#This was a retrospective, analytical, single-center study of admitted patients from January 2016 to December 2021. Clinical factors were analyzed and NLR and ANC were derived from CBC and interpreted using the Manroe chart.@*Results@#Included were 200 neonates with a median birth AOG of 38 weeks. Microorganisms were isolated from nine of 154 neonates with blood culture, corresponding prevalence of 5.84% (95% CI 2.71–10.80). Initial CBC showed elevated mean WBC and 76.5% of neonates were considered to have elevated ANC. Optimal cut-off point of NLR for detecting culture-proven sepsis was 2.86, with a sensitivity of 88.89% (95% CI, 51.75–99.72%) and specificity of 36.55% (95% CI, 28.72–44.95%). The ANC gave the best balance of sensitivity and specificity with an accuracy of 75.50%.@*Conclusions@#The NLR demonstrated good discriminative ability for predicting clinical neonatal sepsis based on ANC. However, individually or simultaneously, these markers demonstrated poor discriminative ability for culture-proven neonatal sepsis in term neonates. ANC and NLR can be used to aid in the diagnosis of clinical neonatal sepsis.

Adherencia a las recomendaciones de prevención de la sepsis neonatal temprana asociada a la colonización por Streptococcus agalactiae en una institución de referencia en Bogotá, Colombia, 2019 / Adherence to recommendations for preventing early neonatal sepsis associated with Streptococcus agalactiae colonization in a referral center in Bogotá, Colombia, 2019

RESUMEN Objetivos: Evaluar la adherencia a las recomendaciones de tamización para la prevención de la sepsis neonatal, describir la prevalencia de colonización por estreptococo del grupo B y los desenlaces perinatales asociados a la colonización por esta bacteria. Materiales y métodos: Estudio de cohorte retrospectiva que incluyó gestantes a término y sus recién nacidos, en una clínica universitaria privada de alta complejidad en Bogotá, entre el 1 de julio y el 31 de diciembre de 2019. Se evaluó la adherencia a la tamización y a la profilaxis antibiótica intraparto para las gestantes colonizadas con EGB, la prevalencia de colonización y los desenlaces perinatales adversos tempranos. Resultados: Se incluyeron 1.928 mujeres. La adherencia a la tamización fue de 68,0 % (IC 95 %: 66-70,1), a la administración de antibióticos intraparto de 87,9 % (IC 95 %: 87,8 -88), pero hubo uso no indicado de antibióticos en 14,7 % de mujeres para una adherencia final a profilaxis antibiótica de 86,3 %. La prevalencia de colonización por EGB fue 12,5 % (IC 95 %: 10,7-14,3), la incidencia de hospitalización neonatal fue de 27,5 % (IC 95 %: 16,3-33,7); no hubo casos de mortalidad ni sepsis neonatal temprana atribuibles al estado de tamización, colonización o profilaxis antibiótica para EGB. Conclusiones: Se requieren nuevos estudios en otras instituciones para determinar la adherencia a esta guía, en especial en aquellas regiones que atienden usuarias adscritas al régimen subsidiado, con cobertura a la población más vulnerable, así como nuevos estudios poblacionales de prevalencia de EGB y costo-efectividad de la estrategia de tamización universal en comparación con la profilaxis antibiótica basada en factores de riesgo.

ABSTRACT Objectives: To assess adherence to screening recommendations for the prevention of neonatal sepsis, and describe the prevalence of colonization by Group B streptococcus (GBS) as well as the perinatal outcomes associated with colonization by this bacterium. Material and methods: Retrospective cohort study that included pregnant women at term and their newborns, seen at a private high-complexity clinic in Bogota, between July 1 and December 31, 2019. Adherence to screening and intrapartum antibiotic prophylaxis in pregnant women colonized with group B streptococcus, as well as the prevalence of colonization and early adverse perinatal outcomes were assessed. Results: Overall, 1928 women were included. Adherence to screening was 68.0 % (95 % CI: 66-70.1) and 87.9 % to intrapartum antibiotic administration (95 % CI: 87.8-88); non-indicated use of antibiotics occurred in 14.7 % of the women, for 86.3 % final adherence to antibiotic prophylaxis. The prevalence of GBS colonization was 12.5 % (95 % CI: 10.7-14.3); the incidence of neonatal hospitalization was 27.5 % (95 % CI: 16.3-33.7). There were no cases of mortality or early neonatal sepsis attributable to screening status, colonization or prophylactic antibiotics for GBS. Conclusions: Additional studies in other centers are required in order to determine adherence to this guideline, particularly in those that receive users affiliated to the subsidized regime which covers the most vulnerable population. Also, new population studies of GBS prevalence and cost-effectiveness of universal screening compared to risk factor-based antibiotic prophylaxis are needed.

Sepsis neonatal precoz: recomendaciones para su abordaje en la práctica clínica / Early neonatal sepsis: recommendations for approach in clinical practice / Sepse neonatal precoce: recomendações para sua abordagem na prática clínica

La sepsis neonatal precoz se define como la que se manifiesta en las primeras 72 horas de vida. Es una importante causa de morbilidad y mortalidad neonatal. Su incidencia es inversamente proporcional a la edad gestacional. Los microorganismos considerados como frecuentes son Streptoccocus del grupo B, Escherichia coli y Listeria monocytogenes. El diagnóstico de sepsis precoz se basa principalmente en la presencia de factores de riesgo como la corioamnionitis y la edad gestacional. Los signos clínicos son inespecíficos y los exámenes paraclínicos disponibles actualmente, como los reactantes de fase aguda (proteína C reactiva y procalcitonia) tienen escaso valor predictivo positivo. Se realizó una revisión bibliográfica de las últimas publicaciones disponibles sobre sepsis neonatal precoz en recién nacidos, en cuanto a su sospecha, confirmación diagnóstica y tratamiento. A partir de las últimas publicaciones se confeccionó una guía para el manejo clínico de los recién nacidos con sospecha de sepsis precoz.

Early neonatal sepsis is defined as that type of sepsis with an onset within the first 72 hours of life and that is a major cause of neonatal morbidity and mortality. Its incidence is inversely proportional to its gestational age. Frequent microorganisms are group B Streptococcus, Escherichia coli and Listeria monocytogenes. Early sepsis diagnosis is mainly based on the presence of risk factors such as chorioamnionitis and gestational age. Clinical signs are non-specific and currently available paraclinical tests such as acute phase reactants (C-reactive protein and procalcitonin) have little positive predictive value. A bibliographic review of the suspicion, diagnostic confirmation and treatment on Early Neonatal Sepsis in newborns in the latest papers and guidelines were prepared for the clinical treatment of newborns with suspected early sepsis.

A sepse neonatal precoce é definida como aquela que se manifesta nas primeiras 72 horas de vida e que é uma das principais causas de morbidade e mortalidade neonatal. Sua incidência é inversamente proporcional à idade gestacional. Os microrganismos considerados frequentes são o Streptococcus grupo B, Escherichia coli e Listeria monocytogenes. O diagnóstico de sepse precoce baseia-se principalmente na presença de fatores de risco como a coioamnionite e a idade gestacional. Os sinais clínicos são inespecíficos e os testes para-clínicos atualmente disponíveis, como reagentes de fase aguda (proteína C-reativa e procalcitonia) têm pouco valor preditivo positivo. Fizemos uma revisão bibliográfica das últimas publicações disponíveis sobre sepse neonatal precoce em recém-nascidos em termos de suspeita e confirmação diagnóstica e tratamento. Com base nas últimas publicações, elaboramos um guia para o manejo clínico de recém-nascidos com suspeita de sepse precoce.

Sepsis precoz, osteoartritis y meningitis: a propósito de un caso clínico / Early sepsis, osteoarthritis and meningitis: a clinical case / Sepse precoce, osteoartrite e meningite: relato de caso

Se expone el caso de un recién nacido que desarrolló sepsis connatal precoz a Streptococcus agalactiae, con meningitis aguda supurada y osteoartritis de rodilla izquierda. Como factor de riesgo la madre no tenía realizado el exudado rectovaginal, pesquisa que detecta la colonización por estreptococo del grupo B (EGB). Se aisló el germen en hemocultivo y en líquido de punción articular. Recibió tratamiento antibiótico adecuado a la sensibilidad del microorganismo y según pauta de sepsis con meningitis, evolucionando favorablemente. En este trabajo se describe la epidemiología de la sepsis neonatal y los cambios ocurridos luego de la implementación de la profilaxis antibiótica en el preparto.

We hereby present the case of a newborn with early connatal sepsis due to Streptococcus agalactiae, with acute suppurative meningitis and left knee osteoarthritis. As a risk factor, the mother had not performed the rectus vaginal exudate screening that detects colonization by Group B Streptococcus (GBS). The germ was isolated in blood culture and in joint puncture fluid. The patient received germ-sensitive antibiotic treatment for meningitis sepsis and evolved favorably. This paper describes the epidemiology of neonatal sepsis and the changes that have occurred after the administration of the antibiotic prophylaxis during pregnancy.

Apresentamos o caso de um recém-nascido com sepse neonatal precoce por Streptococcus agalactiae, com meningite supurativa aguda e osteoartrite de joelho esquerdo. Como fator de risco, a mãe não realizou teste de exsudato vaginal do reto que detecta a colonização por estreptococos do grupo B (SGB). O germe foi isolado em hemocultura e líquido de punção articular. A paciente recebeu tratamento com antibióticos germinativos para padrão meningite sepse e evoluiu favoravelmente. Este artigo descreve a epidemiologia da sepse neonatal e as mudanças ocorridas após a administração da profilaxia antibiótica durante a gravidez.

Características epidemiológicas da mortalidade neonatal e infantil em uma regional de saúde / Epidemiological characteristics of neonatal and infant mortality in a health regional area

Objetivou-se analisar o perfil epidemiológico e as causas da mortalidade neonatal e infantil, em uma Regional de Saúde, de janeiro/2018 a agosto/2020. Trata-se de pesquisa exploratória, descritiva, transversal, retrospectivo, com abordagem quantitativa. A coleta de dados ocorreu em agosto de 2020, por meio de questionário elaborado pelas pesquisadoras, com base nas declarações de óbito disponibilizadas no Sistema de Informações de Mortalidade. O instrumento abordou as variáveis, sexo, raça, cor, idade da criança, idade materna, escolaridade materna, via de parto, idade gestacional, peso ao nascer, causa do óbito. Os dados foram submetidos à análise estatística descritiva e distribuição de frequência, por meio do Statistical Package for the Social Sciences (SPSS), versão 25.0. Constatou-se o predomínio de óbitos no sexo masculino (56,5%), de raça branca (87,8%), com equivalência entre extremo baixo peso e adequado (31,3%), com a principal causa de óbito por septicemia (13,9%). Quanto aos dados maternos, prevaleceram idade entre 21 e 30 anos de idade (45,2%) com gestação única (85,21%) e parto cesariano (65,2 %). Desses, 47,87% ocorreram no ano de 2018. Analisar os aspectos da mortalidade neonatal e infantil possibilita o planejamento e a readequação de ações no atendimento à saúde da criança, durante o período mais vulnerável e mais crítico dela, contribuindo, assim, para redução do número de óbitos.

This study analyzed the epidemiological profile and the causes of neonatal and infant mortality in a Health Regional Area between January 2018 and August 2020. This is an exploratory, descriptive, cross-sectional, retrospective study with a quantitative approach. Data collection took place during August 2020 through a questionnaire prepared by the researchers, based on the death certificates available in the Mortality Information System. The instrument included the variables of sex, race, color, child's age, mother's age, maternal education, childbirth mode, gestational age, birth weight, cause of death. The data were submitted to descriptive statistical analysis and frequency distribution using the Statistical Package for the Social Sciences (SPSS) version 25.0. There was a predominance of deaths among boys (56.5%), Caucasian (87.8%), with equivalence between extreme low and adequate weight (31.3%), with the main cause of death being septicemia (13.9%). As for maternal data, age between 21 to 30 years old (45.2%) prevailed, and 85.21% had a single pregnancy, with C-section childbirth (65.2%). From these, 47.87% occurred in 2018. It can be concluded that analyzing the aspects of neonatal and child mortality enables the planning and adjustment of actions in child health care during its most vulnerable and most critical period, thus contributing to reducing the number of deaths.

Fatores perinatais associados à sepse neonatal precoce em uma maternidade-escola do sul do Brasil / Perinatal factors associated with early neonatal sepsis in the maternity ward of a teaching hospital in southern brazil

Introdução: Sepse neonatal é uma condição potencialmente fatal, que constitui um problema de saúde pública de impacto global e é responsável por taxas expressivas de morbidade e mortalidade. O objetivo deste artigo é estimar os fatores associados à sepse neonatal precoce em uma maternidade-escola do sul do Brasil. Métodos: Realizou-se estudo de caso-controle para observar eventual associação entre fatores relacionados à sepse neonatal precoce e características clínicas e sociodemográficas maternas e fatores perinatais dos recém-nascidos, utilizando-se dados de prontuários de pacientes no período entre 2014 e 2017. A amostra foi composta por 293 binômios mãe/recém-nascido, sendo 1 caso para 2 controles. Todas as variáveis com valores de p< 0,05 na análise bivariada foram incluídas em uma análise multivariada por meio de Regressão Logística. Resultados: Idade gestacional menor que 37 semanas (OR 19,6 IC 95% 5,3; 73,0) (p<00,1) e presença de fator de risco para Streptococcus agalactiae beta hemolítico (SGB) (OR 5,1 IC 95% 1,2; 21,8) (p=0,027) foram as exposições independentemente associadas à sepse neonatal precoce. Conclusão: Identificou-se maior chance de desenvolver sepse neonatal precoce quando prematuridade e fatores de risco maternos para SGB estão presentes. Assim, medidas mais eficazes de prevenção e controle desses fatores são de extrema importância.

Introduction: Neonatal sepsis is a potentially fatal condition that constitutes a public health problem worldwide, being responsible for significant rates of morbidity and mortality. The objective of this study was to identify factors associated with early neonatal sepsis in the maternity ward of a teaching hospital in Southern Brazil. Methods: We conducted a case-control study to identify if factors related to early neonatal sepsis are associated with maternal clinical and sociodemographic characteristics and perinatal factors of infants, using data from patient records between 2014 and 2017. The sample consisted of 293 mother/newborn binomials, 1 case for 2 controls. All variables with p-values < 0.05 in the bivariate analysis were included in a multivariate analysis using logistic regression. Results: A gestational age < 37 weeks (odds ratio [OR] 19.6; 95%CI 5.3; 73.0) (p < 00.1) and the presence of a risk factor for beta-hemolytic Streptococcus agalactiae (GBS) (OR 5.1; 95%CI 1.2; 21.8) (p = 0.027) were independently associated with early neonatal sepsis. Conclusions: Prematurity and the presence of maternal risk factors for GBS increase the likelihood of developing early neonatal sepsis. Thus, more effective measures to prevent and control these factors are extremely important.

La sepsis neonatal es una importante causa de morbimortalidad. Se realizó un proceso investiga-tivo con el objetivo de describir la etiología y el patrón de susceptibilidad antimicrobiana de las bacterias aisladas más frecuentemente de los hemocultivos de neonatos con sepsis en el servicio de neonatología del Hospital General Docente de Ambato. La metodología empleada en esta investigación se basó en un estudio descriptivo, transversal y enfoque cuali-cuantitativo, empleando la técnica documental y el reporte de resultados como instrumento. De los 39 pacien-tes estudiados 64,10% fueron del género masculino. El 23,07% presentaron bajo peso y 33,33% una edad gestacional <37 semanas. El microorganismo más frecuente fue Staphylococcus epidermidis (51,28%) seguido de Escherichia coli (17,94%) y Staphylococcus aureus (15,38%). En relación al perfil de susceptibilidad antimicrobiana S. epidermidis y S. aureus se mostraron sensibles a linezolid y vancomicina en más del 80,00%, y presentaron alta resistencia a oxacilina (80,00 y 83,33%, respectivamente), estas cepas expresaron fenotípicamente el gen mecA. Las enterobacterias aisladas mostraron resistencia a amoxacilina/ácido clavulánico (61,53%), ampi-cilina/sulbactam (69,23%), ciprofloxacina (61,53%), ceftazidima (30,76%) y cefotaxima (38,46%). Además, cinco cepas de E. coli y Klebsiella pneumoniae eran fenotípicamente productoras de beta lactamasas de espectro extendido. En conclusión, es necesario realizar estu-dios locales de vigilancia microbiológica en los hospitales, con el fin de identificar los patógenos multirresistentes involucrados en las infecciones neonatales, reconocer los brotes y monitorizar los cambios que ocurren a través del tiempo; los cuales influyen finalmente, en la elección de los tratamientos empíricos.

Neonatal sepsis is a major cause of morbidity and mortality. The investigative process was carried out to describe the etiology and antimicrobial susceptibility pattern of the bacteria most frequently isolated from blood cultures of neonates with sepsis in the neonatology service of the Ambato General Teaching Hospital. The methodology used in this research was based on a descriptive, cross-sectional study and a quali-quantitative approach, using the documentary technique and the report of results as an instrument. 39 patients were studied, 64.10% of them were male. 23.07% had low weight and 33.33% had a gestational age <37 weeks. The most frequent microorganism was Staphylococcus epidermidis (51.28%), followed by Escherichia coli (17.94%) and Staphylococcus aureus (15.38%). In relation to the antimicrobial susceptibili-ty profile, S. epidermidis and S. aureus were sensitive to linezolid and vancomycin in more than 80.00% and presented high resistance to oxacillin (80.00 and 83.33%, respectively), these strains phenotypically expressed the mecA gene. Isolated Enterobacteriaceae showed resistance to amoxacillin / clavulanic acid (61.53%), ampicillin / sulbactam (69.23%), ciprofloxacin (61.53%), ceftazidime (30.76%) and cefotaxime (38.46%). Furthermore, five strains of E. coliand Klebsiella pneumoniae were phenotypically producers of extended spectrum beta lactama-ses. In conclusion, it is necessary to perform local microbiological surveillance studies in hospi-tals in order to identify multi-resistant pathogens involved in neonatal infections, recognize outbreaks and monitor the changes that occur over time, which influence the choice of empirical treatments.

Efficacy of oropharyngeal administration of pasteurized colostrum in very low birthweight newborns in reducing late onset sepsis at a tertiary government hospital in Manila City: A randomized control trial

Background@#Early administration of colostrum is beneficial because of the number of its immunologic components. The problem with very low birthweight (VLBW) patients is the establishment of early, tolerated, and sustained feeding. The study aimed to determine if early initiation of colostrum through oropharyngeal administration within the first hour of life reduces the risk of late-onset sepsis (LOS) among VLBW newborns. @*Methods@#In this single-blinded randomized control trial, 84 VLBW infants with pediatric aging equal to greater than 28 weeks requiring oxygen support were enrolled. They were allocated to receive either pasteurized colostrum via oropharyngeal administration (treatment group) or none (control group). The occurrence of LOS, duration of ventilator use and oxygen support, time to reach full feeds, length of NICU stay, the occurrence of NEC, and mortality were documented. @*Results@#A significantly greater proportion of patients who developed LOS were noted in the control group (n=38 (90.4%)) than in the treatment group (n=30 (71.4%)) (p=0.013). The use of colostrum, had a protective effect for LOS (RR=0.77; 95% CI=0.63-0.94). There were no significant differences in the secondary outcomes. Still, there was a trend towards a lower proportion of mortality (p=0.08), shorter duration of ventilator use (p=0.24) and oxygen support (p=0.17), shorter time to reach full feeds (p=0.30), and shorter NICU stay (p=0.33) in the treatment group. @*Conclusion@#Patients given pasteurized colostrum had significantly less occurrence of LOS. The treatment group had a lower mortality rate, shorter ventilator use and oxygen support duration, faster time to reach full feeds, and shorter NICU stay, but the differences were not statistically significant. Oropharyngeal administration of pasteurized colostrum within the first hour of life reduces the risk of LOS among VLBW infants admitted to the NICU.

Bacteriology and outcome of Neonatal Septicaemia: Experience from a mission hospital in Nigeria

Introduction@#One in every three preventable under-five deaths occur in the neonatal period and one of the leading causes of neonatal death in Low and Middle-Income Countries (LMIC) is sepsis. Organisms isolated varies between and within geographical locations, its trend changes with time. Each setting hence needs to have its antibiogram for susceptible isolates to optimize treatment outcome, the background on which this study was conducted. @*Methodology@#A retrospective study was done on neonates admitted to the Neonatal Intensive Care Unit of Bowen University Teaching Hospital, a missionary hospital in South West Nigeria, between January 2016 and December 2017. The medical records of these neonates were retrieved from the comprehensive electronic database for all neonates admitted into the unit. @*Result@#Of the 129 newborns eligible for the study, early-onset sepsis (56.6%) predominated. There were 79 (61%) males giving a M:F ratio of 1.6:1. The incidence rate of neonatal sepsis was 15 per 1,000 live births with a mortality rate of 24%. Gram-Negative Bacilli were mostly isolated in positive cultures. The likelihood of getting a positive culture was unrelated to the age and sex of patients at presentation. There was a varying resistance pattern of the isolates to commonly used empiric antibiotics. @*Conclusion and Recommendation@#Gram-Negative Bacilli was the commonest cause of neonatal sepsis in our center, associated with poor outcome. The high incidence of resistance to the commonly used empirical treatment calls for an urgent review of practice if the trend of high morbidity and mortality would be curtailed, as well as improved infection control practices.

Hernia of the cord with patent omphalomesenteric duct and ileal prolapse in two preterm neonates: case series

@#Hernia of the cord (HOC) is a rare condition that results from failure of the viscera to return to the abdominal cavity by the 10th week of fetal development. It sometimes presents together with a patent omphalomesenteric duct (POMD), another rare condition, which occurs earlier in fetal development. A proportion of POMD cases may also have ileal prolapse (IP) through the POMD lumen. Neonates diagnosed with the combination of these rare clinical conditions require immediate surgical intervention to resect the POMD and non-viable bowel segments, reduce the hernia, and repair the umbilical defect. In this case series, we report two neonates diagnosed with HOC with POMD and IP. One patient who had complete IP was not fit for immediate surgery and died of respiratory distress and sepsis. The other patient had a successful surgical correction of the congenital defects, but succumbed to sepsis postoperatively. Treatment of patients with this combination of clinical conditions should focus mainly on both surgical correction, and infection control and management.

Diagnostic accuracy of the neonatal early onset sepsis calculator in screening for early onset sepsis in neonates more than 35 weeks age of gestation

Background@#Early-onset sepsis (EOS) is a leading cause of morbidity and mortality among neonates. Diagnosis of EOS can be difficult as clinical signs are subtle. The use of the Neonatal EOS Calculator (NEOSC) may help screen high-risk neonates for EOS and may result in a significant reduction in unnecessary antibiotic use. @*Objective@#To determine the diagnostic accuracy of the NEOSC in screening for EOS in neonates more than 35 weeks age of gestation. @*Methodology@#This was a retrospective, case-control study where 245 septic (cases) and 245 non-septic (controls) neonatal and maternal medical records were reviewed. The EOS risk classification from the NEOSC was compared with the actual clinical outcome. An online statistical software (medcalc.org) was used to compute for the sensitivity (Sn), specificity (Sp), positive predictive value (PPV), negative predictive value (NPV), positive likelihood ratio (PLR), negative likelihood ratio (NLR) and accuracy of the NEOSC. @*Results@#Based on the NEOSC, only 64 of 245 clinically septic neonates were truly positive for sepsis while 181 were falsely negative for sepsis. Of the 245 non-septic neonates, 3 were falsely positive for sepsis, while 242 were truly negative for sepsis. With a 95% confidence interval, the computed variables showed a Sn 26.12%, Sp 98.78%, PPV 76.12%, NPV 89.95%, PLR 21.33, and NLR 0.75. The accuracy of the NEOSC is 89.33%.@*Conclusion@#The NEOSC had poor sensitivity and is not recommended in screening for EOS in neonates more than 35 weeks age of gestation. It may be used as an adjunct in EOS diagnosis due to its high specificity and accuracy.

Mortalidad por sepsis neonatal entre los años 2016 y 2020 en Chile: una mirada nacional / Mortality due to neonatal sepsis between 2016 and 2020 in Chile: a national perspective

Introducción: La sepsis neonatal (SN) es una infección sistémica que ocurre antes de los 90 días de vida y que representa una amenaza potencialmente mortal. Esta investigación busca describir la tendencia de defunción por SN en Chile, durante el periodo 2016-2020. Materiales y métodos: Estudio descriptivo observacional, que incluyó a niños fallecidos por SN (n=249) en el periodo 2016-2020 en Chile según datos del departamento de estadísticas e información de salud de Chile. Las variables estudiadas fueron: año de fallecimiento, grupo etario, sexo, región y agente etiológico. No se requirió comité de ética. Resultados: El 2020 tuvo la menor tasa de mortalidad por SN (0,17) y el 2017 la mayor (0,31). El grupo etario de 0-2 días de nacido tuvo la mayor tasa de mortalidad (0,07), mientras que el grupo de 27-28 días corresponde a la menor (0,00). La región de Antofagasta tuvo la mayor mortalidad (0,44) y la región de Magallanes la menor (0,11). La tasa de mortalidad promedio en hombres corresponde a 0,12 y en mujeres a 0,10. En el 89,16% de los casos no se identificó el agente etiológico. Discusión: La mayor mortalidad en 2017 podría deberse a una proporción más alta de nacimientos pretérmino en dicho año. La mayor cantidad de defunciones a menor edad cronológica estaría relacionada con su inmadurez inmunológica. La no detección del agente etiológico pudo deberse al bajo rendimiento de los hemocultivos. Sin embargo, faltan más investigaciones acerca de la incidencia y mortalidad por sepsis neonatal.

Introduction: Neonatal sepsis (NS) is a systemic infection that occurs before 90 days of life and represents a life-threatening threat. This research seeks to describe the trend of death by NS in Chile, during the period 2016-2020. Materials and methods: Observational descriptive study, which included children who died due to NS (n=249) in the period 2016-2020 in Chile, according to data from the Department of Statistics and Health Information of Chile. The variables studied were: year of death, age group, sex, region and etiological agent. No ethics committee was required. Results: 2020 had the lowest mortality rate due to NS (0.17) and 2017 the highest (0.31). The age group of 0-2 days of birth had the highest mortality rate (0.07), while the group of 27-28 days corresponds to the lowest (0.00). The Antofagasta region had the highest mortality (0.44) and the Magallanes region the lowest (0.11). The average mortality rate in men corresponds to 0.12 and in women to 0.10. In 89.16% of the cases, the etiological agent was not identified. Discussion: The higher mortality in 2017 could be due to a higher proportion of preterm births in that year. The greater number of deaths at a lower chronological age would be related to their immunological immaturity. The non-detection of the etiological agent could be due to the low yield of the blood cultures. However, more research on the incidence and mortality from neonatal sepsis is lacking.

Neonatal morbidity and mortality: A 5-year analysis at federal medical centre, Gusau, Zamfara State, Northwest Nigeria

OBJECTIVES: Neonatal morbidity and mortality have remained embarrassingly high in Nigeria compared to some countries in Sub-Saharan Africa. Nigeria ranked first in the burden of neonatal deaths in Africa. Therefore, there is need to know causes of newborn diseases and deaths in our neonatal unit. The objective of the study was to describe the morbidity and mortality of newborns admitted into Special Care Baby Unit of Federal Medical Centre, Gusau, Nigeria over a 5-year period. MATERIAL AND METHODS: This is a retrospective study covering January 2012 to December 2016. The case folders of all newborns admitted during this period were retrieved and the following information were extracted: Sex of babies, diagnoses, outcome in terms of discharges, deaths, referrals, and discharge against medical advice (DAMA). RESULTS: A total of 3,553 neonates were admitted during the period under review. The sex ratio for males and females was 1.4:1, respectively. The major diagnoses were neonatal sepsis (NNS) 36.5%, birth asphyxia 25.6%, and prematurity 16.1%. Mortality rate was 6.6% with major contributions from birth asphyxia (35.6%), prematurity (28.1%), and NNS (12.0%). DAMA rate was 1.7%. CONCLUSION: This study has shown that NNS, birth asphyxia, and prematurity are the dominant causes of morbidity and mortality. These are largely preventable.

Metabolomic changes of neonatal sepsis: an exploratory clinical study / 中国当代儿科杂志

OBJECTIVES@#To study the metabolic mechanism of neonatal sepsis at different stages by analyzing the metabolic pathways involving the serum metabolites with significant differences in neonates with sepsis at different time points after admission.@*METHODS@#A total of 20 neonates with sepsis who were hospitalized in the Department of Neonatology, Hunan Provincial People's Hospital, from January 1, 2019 to January 1, 2020 were enrolled as the sepsis group. Venous blood samples were collected on days 1, 4, and 7 after admission. Ten healthy neonates who underwent physical examination during the same period were enrolled as the control group. Ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry was used for the metabonomic analysis of serum samples to investigate the change in metabolomics in neonates with sepsis at different time points.@*RESULTS@#On day 1 after admission, the differentially expressed serum metabolites between the sepsis and control groups were mainly involved in the biosynthesis of terpenoid skeleton. For the sepsis group, the differentially expressed serum metabolites between days 1 and 4 after admission were mainly involved in pyruvate metabolism, and those between days 4 and 7 after admission were mainly involved in the metabolism of cysteine and methionine. The differentially expressed serum metabolites between days 1 and 7 after admission were mainly involved in ascorbic acid metabolism.@*CONCLUSIONS@#The metabolic mechanism of serum metabolites varies at different stages in neonates with sepsis and is mainly associated with terpenoid skeleton biosynthesis, pyruvate metabolism, cysteine/methionine metabolism, and ascorbic acid metabolism.
