Impact of Oropharyngeal Administration of Colostrum in Preterm Newborns' Oral Microbiome.

The initial colonization of the human microbiota is of paramount importance. In this context, the oropharyngeal administration of colostrum is a safe, viable, and well-tolerated practice even by the smallest preterm infants. Therefore, this study evaluated the effects of oropharyngeal administration of colostrum on the establishment of preterm infants' oral microbiota. A longitudinal observational study was carried out with 20 premature neonates, divided into two groups: one receiving the protocol (Oropharyngeal Administration of Colostrum; OAC) and the other one receiving Standard Caare (SC). Saliva samples were collected from the newborns weekly during the study period (from the day of birth until the 21st day of life) for analysis of oral microbiota through 16S rRNA gene sequencing. We observed that the colonization of the oral microbiota of preterm newborns preseanted a higher relative abundance of Staphylococcus on the 7th day of life, mainly in the OAC group. Additionally, an increased abundance of Bifidobacterium and Bacteroides was observed in the OAC group at the first week of life. Regarding alpha and beta diversity, time was a key factor in the oral modulation of both groups, showing how dynamic this environment is in early life.

Caracterização da evolução clínica dos recém-nascidos com gastrosquise em uma unidade de terapia intensiva neonatal de referência da américa latina / Characteristics of the clinical development of a newborn with gastroschisis in an intensive care unit in latin america

INTRODUCTION: Congenital malformations are major diseases observed at birth. They are the second most common cause of death in the neonatal population, the first one being prematurity. OBJECTIVE: To characterise the clinical outcome of newborns with gastroschisis (GS) in a neonatal intensive care unit. METHODS: A retrospective observational clinical study in 50 infants with GS using the association of intestinal abnormalities, impossibility of primary closure of the abdominal defect and reoperation necessity as classification criteria for the disease. The significance level was p < 0.05. RESULTS: The hospitalisation to primary surgery occurred with a median age of 2 hours. Fourteen percent of children were subjected to a primary silo interposition and 24% had associated intestinal malformation. Nineteen newborns (NB) required more than one surgery. The median length of stay was 33 days, higher in patients with complex GS (56 days). All NB recovered from urine output 48 hours after surgery and 40% had hyponatraemia and oligoanuria in this period. There was no difference between the natraemia and fasting time (p = 0.79). Weight gain was similar in both groups with total parenteral nutrition and became significantly higher in patients with simple GS after enteral feeding (p = 0.0046). These NB evolved 2.4 times less cholestasis. Late-onset sepsis occurred in 58% of patients and was related to the infection of the central venous catheter in 37.9% of cases. Mortality was higher in infants infected with complex GS and the overall mortality rate was 14%. CONCLUSION: Clinical characterisation of newborns with gastroschisis depends on the complexity and the knowledge and conduct of morbidities to reduce mortality.

INTRODUÇÃO: As malformações congênitas fazem parte das principais doenças observadas ao nascimento. Entre as causas de óbito no período neonatal as malformações foram a segunda causa, sendo ainda a primeira, a prematuridade. OBJETIVOS: Caracterizar a evolução clínica dos recém-nascidos (RN) com gastrosquise (GTQ) em uma unidade de terapia intensiva neonatal e descrever as morbidades renal, nutricional e infecciosa relacionados ao manejo clínico pós-natal na unidade de terapia intensiva neonatal MÉTODO: Foi realizado estudo observacional retrospectivo em 50 RN com GTQ, utilizando a associação de anormalidades intestinais, impossibilidade de fechamento primário do defeito abdominal e necesidade de reoperação como critérios de classificação para a doença. O nível de significância foi p < 0,05. RESULTADOS: A admissão hospitalar para cirurgia primária ocorreu com mediana de idade de 2 horas. O total de 14% das crianças foram submetidas a uma interposição de silo primária e 24% apresentaram malformação intestinal associada. Dezenove RN necessitaram mais de uma intervenção cirúrgica. A mediana do tempo de estadia foi de 33 dias, sendo maior nos pacientes com GTQ complexa (56 dias). Todos os RN recuperaram o débito urinário a partir de 48 horas do pós-operatório e 40% apresentaram hiponatremia e oligoanúria nesse período. Não houve diferença entre a natremia e o tempo de jejum (p = 0,79). O ganho ponderal foi similar em ambos os grupos com nutrição parenteral total e tornou-se significativamente maior nos pacientes com GTQ simples após a alimentação enteral (p = 0,0046). Esses RN evoluíram 2,4 vezes com menos colestase. Sepse tardia ocorreu em 58% dos pacientes e foi relacionada à infecção do CVC em 37,9% dos casos. A mortalidade foi maior nos RN infectados com GTQ complexa e a taxa global de mortalidade foi de 14%. CONCLUSÃO: A caracterização clínica dos RN com GTG depende da complexidade e do conhecimento e condução das morbidades para diminuir a mortalidade.

O impacto da introdução precoce de terapia nutricional enteral na redução da morbimortalidade na terapia intensiva pediátrica: uma revisão sistemática / Early enteral nutrition therapy and mortality in a pediatric intensive care unit

OBJETIVO: Avaliar o impacto da introdução precoce de terapia nutricional enteral na redução da morbimortalidade em unidades de terapia intensiva pediátrica. MÉTODOS: Pesquisa bibliográfica nas bases de dados PubMed, Lilacs e Embase dos últimos 10 anos, em língua inglesa e população-alvo de indivíduos de 1 mês de idade a 18 anos, internados em unidades de terapia intensiva pediátrica, usando as palavras-chave: Critical Care, Nutritional Support e Nutrition Disorders or Malnutrition. RESULTADOS: Apesar dos avanços na qualidade dos cuidados clínicos, a prevalência de desnutrição em crianças hospitalizadas permanece imutável nos últimos 20 anos (15-30%) e tem implicações no tempo de internação, curso da doença e morbidade. A desnutrição é comum e é com frequência pouco reconhecida e então, não tratada. A terapia nutricional é parte essencial no tratamento dos pacientes pediátricos gravemente doentes que apresentam estado de hipercatabolismo proteico, que pode ser minimizado com um plano terapêutico nutricional efetivo. Neste estudo, foram revisadas publicações que mostraram que ainda há uma escassez de pesquisas controladas e randomizadas com bom tratamento estatístico em relação à terapia nutricional enteral com desfecho relacionado à morbimortalidade. As diretrizes atuais para terapia nutricional desses pacientes são amplamente baseadas na opinião de experts e em dados extrapolados de estudos em adultos, bem como de estudos realizados em crianças saudáveis. CONCLUSÃO: A evidência científica na utilização de terapia nutricional enteral na melhora da evolução dos pacientes pediátricos gravemente doentes ainda é escassa e são necessários novos estudos focados nisso, além de diretrizes mais bem-formuladas.

OBJECTIVE: To assess the impact of early introduction of enteral nutrition therapy in reducing morbidity and mortality in pediatric intensive care unit. METHODS: Search in the literature of the last 10 years, in English and the target population of individuals aged 1 month to 18 years admitted to pediatric intensive care units in the databases PubMed, Lilacs and Embase using the keywords: Critical Care, Nutritional Support and Nutrition Disorders or Malnutrition. RESULTS: Despite advances in the quality of clinical care, the prevalence of malnutrition in hospitalized children remains unchanged in the last 20 years (15-30%) and has implications for the time of admission, course of illness and morbidity. Malnutrition is common and is often poorly recognized and therefore, untreated. Nutritional therapy is an essential part in the treatment of pediatric patients who have severely ill hypercatabolic state protein, which can be minimized with an effective nutritional treatment plan. In this study, we reviewed publications which have shown that there is still a paucity of randomized and controlled studies with good statistical treatment in relation to enteral nutritional therapy with outcomes related to morbidity and mortality. The current guidelines for nutritional therapy in these patients are largely based on expert opinion and data extrapolated from adult studies and studies in healthy children. CONCLUSION: The scientific evidence on the use of enteral nutrition therapy in improving the development of critically ill pediatric patients is still scarce and further studies are needed focusing on it, and better guidelines must be formulated.

Nutrition therapy in a pediatric intensive care unit: indications, monitoring, and complications.

BACKGROUND: Nutrition therapy (NT) is essential for the care of critically ill children. Inadequate feeding leads to malnutrition and may increase the patient's risk of morbidity and mortality. The aim of this study was to describe the NT used in a tertiary pediatric intensive care unit (PICU). METHODS: The authors evaluated NT administered to 90 consecutive patients who were hospitalized for 7 days in the PICU of Instituto da Criança, Hospital das Clínicas, Universidade de São Paulo, Brazil. NT was established according to the protocol provided by the institution's NT team. NT provided a balance of fluids and nutrients and was monitored with a weekly anthropometric nutrition assessment and an evaluation of complications. RESULTS: NT was initiated, on average, within 72 hours of hospitalization. Most children (80%) received enteral nutrition (EN) therapy; of these, 35% were fed orally and the rest via nasogastric or postpyloric tube. There were gastrointestinal complications in patients (5%) who needed a postpyloric tube. Parenteral nutrition (PN) was used in only 10% of the cases, and the remaining 10% received mixed NT (EN + PN). The average calorie and protein intake was 82 kcal/kg and 2.7 g/kg per day. Arm circumference and triceps skinfold thickness decreased. CONCLUSIONS: The use of EN was prevalent in the tertiary PICU, and few clinical complications occurred. There was no statistically significant change in most anthropometric indicators evaluated during hospitalization, which suggests that NT probably helped patients maintain their nutrition status.

Growth of very low birth weight infants fed with milk from a human milk bank selected according to the caloric and protein value.

OBJECTIVE: To describe growth and clinical evolution of very low birth weight infants fed during hospital stay with milk from a human milk bank according to the caloric-protein value. METHOD: Forty very low birth weight infants were included: 10 were fed milk from their own mothers (GI), and 30 were fed human milk bank > 700 cal/L and 2 g/dL of protein. Growth curves were adjusted using nonlinear regression to the measured growth parameters. RESULTS: full enteral diet was reached in 6.3 days by GI and in 10.8 by GII; a weight of 2 kg was reached in 7.3 weeks for GI and in 7.8 for GII. In GI, 3/10 (33.3%) and in GII, 7/30 (23.3%) developed sepsis. Necrotizing enterocolitis did not occur in GI, but in 3/30 (10.0%) in GII. GI presented with urinary calcium > 4 mg/L in 1/10 (10.0%), urinary phosphorus (Pu) <1 mg/L in 10/10 (100%), and Ca/Cr >0.6 ratio in 1/10 (10.0%) of the cases; in GII, no children presented alterations of the urinary calcium or the Ca and Cr ratio, and Pu was <1 mg/L in 19/30 (63.3%). In terms of growth the 50th percentile for GI was a weight gain of 12.1 g/day (GI) vs. 15.8 g/day (GII), a length gain of 0.75 cm/week (GI) vs. 1.02 cm/week (GII), and a head circumference gain of 0.74 cm/week (GI) vs. 0.76 cm/week (GII). CONCLUSIONS: Human milk bank allowed a satisfactory growth and good clinical evolution for very low birth weight infants.

Monitoring the treatment of sepsis with vancomycin in term newborn infants

A prospective study was conducted to determine if standardized vancomycin doses could produce adequate serum concentrations in 25 term newborn infants with sepsis. Purpose: The therapeutic response of neonatal sepsis by Staphylococcus sp. treated with vancomycin was evaluated through serum concentrations of vancomycin, serum bactericidal titers (SBT), and minimum inhibitory concentration (MIC). METHOD: Vancomycin serum concentrations were determined by the fluorescence polarization immunoassay technique , SBT by the macro-broth dilution method, and MIC by diffusion test in agar . RESULTS: Thirteen newborn infants (59.1 percent) had adequate peak vancomycin serum concentrations (20--40 mg/mL) and one had peak concentration with potential ototoxicity risk (>40 æg/mL). Only 48 percent had adequate trough concentrations (5--10 mg/mL), and seven (28 percent) had a potential nephrotoxicity risk (>10 æg/mL). There was no significant agreement regarding normality for peak and trough vancomycin method (McNemar test : p = 0.7905). Peak serum vancomycin concentrations were compared with the clinical evaluation (good or bad clinical evolution) of the infants, with no significant difference found (U=51.5; p=0.1947). There was also no significant difference between the patients' trough concentrations and good or bad clinical evolution (U = 77.0; p=0.1710). All Staphylococcus isolates were sensitive to vancomycin according to the MIC. Half of the patients with adequate trough SBT (1/8), also had adequate trough vancomycin concentrations and satisfactory clinical evolution. CONCLUSIONS: Recommended vancomycin schedules for term newborn infants with neonatal sepsis should be based on the weight and postconceptual age only to start antimicrobial therapy. There is no ideal pattern of vancomycin dosing; vancomycin dosages must be individualized. SBT interpretation should be made in conjunction with the patient's clinical presentation and vancomycin serum concentrations. Those laboratory and clinical data favor elucidation of the probable cause of patient's bad evolution, which would facilitate drug adjustment and reduce the risk of toxicity or failing to achieve therapeutic doses
