Association between type of feeding at hospital discharge and nutritional status of Brazilian very preterm infants: a multicenter study.

OBJECTIVES: To examine trends over time in diet and size of very preterm infants, and associations of diet with size at hospital discharge/transfer. METHODS: The authors studied 4062 surviving very preterm infants born < 32 weeks' gestational age and < 1500 g between January 2012 and December 2020 from 12 Brazilian Neonatal Intensive Care Units. Diet type at discharge/transfer was classified as exclusive human milk, exclusive formula, or mixed. Outcomes were weight and head circumference at hospital discharge and the change in each from birth to discharge. The authors used linear regression to estimate adjusted associations of diet type with infant size, overall, and stratified by fetal growth category (small vs. appropriate for gestational age). The authors also examined trends in diet and infant size at discharge over the years. RESULTS: Infants' mean gestational age at birth was 29.3 weeks, and the mean birth weight was 1136 g. Diet at discharge/transfer was exclusive human milk for 22 %, mixed for 62 %, and exclusive formula for 16 %. Infant size in weight and head circumference were substantially below the growth chart reference for all diets. Infants fed human milk and mixed diets were lighter and had smaller heads at discharge/transfer than infants fed formula only (weight z: -2.0, -1.8, and -1.5; head z: -1.3, -1.2 and -1.1 for exclusive human milk, mixed and exclusive formula respectively). CONCLUSION: Results suggest high human milk use but gaps in nutrient delivery among hospitalized Brazilian very preterm infants, with little evidence of improvement over time.

Enteral adequacy of the diet of low-birth-weight preterm newborns: A prospective cohort study.

OBJECTIVE: This study aimed to verify the dietary adequacy of full enteral feeding in preterm newborns (PTNB) and its relationship with birth weight (BW) during the period of hospitalization in the neonatal intensive care unit (NICU). METHODS: This is a prospective cohort study whose population were babies born at less than 37 gestational weeks and weighing less than 2500 g, admitted to a NICU. PTNB were monitored regarding their dietary evolution, considering parenteral and enteral nutrition and adequacy of diet supply in terms of volume, energy, and protein. For statistical analysis, the Statistical Package for the Social Sciences (SPSS) software was used, considering p < 0.05 as significant. RESULTS: A total of 76 PTNB were included. The mean time of using parenteral nutrition was 14 days. The mean time to reach the full enteral feeding for nutrition (FEF-N) was 29 days. However, half of the PTNB reached nutritional recommendations after this means. The time to achieve FEF-N was influenced by BW. Additionally, BW significantly influenced the length of stay in the NICU (p < 0.001). When reaching the recommended full enteral feeding for hydration (FEF-H), 60% of the sample was unable to reach the recommended energy and protein intake. CONCLUSIONS: BW influenced the time needed to reach the FEF-H and FEF-N. The lower the BW, the longer it took to achieve dietary adequacy. Despite achieving the FEF-H, most premature babies did not reach the necessary energy and protein intake at the appropriate time.

Hybrid developmental follow-up for preterm infants in Brazil: A feasibility study.

INTRODUCTION: The low attendance of families in child developmental follow-up programs for at-risk preterm children is a challenge in Brazil. OBJECTIVE: This study evaluates the feasibility of implementing a developmental follow-up program for Brazilian preterm infants in a hybrid format. METHODS: This is an observational, prospective cohort study, involving preterm infants. Longitudinal developmental test results, the participation frequency in the program, and the number of referrals to early intervention programs were used to assess feasibility. The General Movements (GMs) assessment, Alberta Infant Motor Scale (AIMS) and, Survey of Wellbeing of Young Children (SWYC) Milestones were administered via telehealth. The Bayley-III was administered in-person. RESULTS: Thirty-four preterm infants attended the follow-up until 12 months of corrected age and 18 (52.9 %) concluded all follow-up assessments. Twenty-six (76.5 %) attended all assessments via telehealth, and 26 (76.5 %) attended the in-person assessment. Eighteen (52.9 %) infants showed at least one altered result in development tests. Infants exhibiting abnormal results in the GMs assessment, motor developmental delay according to the AIMS, or developmental delay based on Balley-III were promptly referred to early intervention services. CONCLUSION: This study demonstrated high participation rate and low dropout in a developmental follow-up program employing a hybrid format. The substantial number of identified infants with developmental delay emphasizes the importance of timely detection of motor delays to referral to early intervention services.

Third stage of the kangaroo method: exclusive breastfeeding and growth of preterm and/or low birth weight newborns.

OBJECTIVE: To evaluate the rates of exclusive breastfeeding (EBF) and growth of preterm and/or low birth weight newborns during the third stage of the Kangaroo Method (TSKM), at discharge. METHODS: Retrospective study in a reference public maternity hospital between Jan/2014 and Dec/2017, including the preterm (less than 37 weeks) and/or low birth weight (less than 2500 g) newborn infants. Information was collected from medical records. Statistics analysis was done in SPSS software. RESULTS: 482 infants were included and followed up at the TSKM ambulatory. The average gestational age was 33 weeks (variation: 24-39 weeks) and birth weight, 1715g (variation: 455-2830 g). EBF occurred in 336 (70.1%) infants at hospital discharge, and in 291 (60.4%) at TSKM discharge. Each additional day of hospital stay increased the chance of infant formula (IF) use by 9.3% at hospital discharge and by 10.3% at TSKM discharge. Staying in the Kangaroo Neonatal Intermediate Care Unit (KNICU) favored EBF at hospital discharge and TSKM discharge (p<0.001). Not performing the kangaroo position increased the chance formula administration to the newborn infant at hospital discharge by 11%. Weight gain and head circumference growth were higher in infants using formula (p<0.001). CONCLUSIONS: The length of hospital stay and not performing the kangaroo position favored the use of infant formula at hospital and TSKM discharge. Staying in the KNICU favored exclusive breastfeeding at hospital and TSKM discharge. Weight gain and HC growth were higher in newborns receiving infant formula.

Association between preterm infant body composition in the first 3 months of life and preschool age: a cohort study.

Compared with full-term infants, preterm infants have fat-free mass deficit in the first months of life, which increases the risk of metabolic diseases in the future. In this cohort of children born under 32-week gestational age or less than 1500 g, we aimed to evaluate the associations of body composition at term equivalent age and in the first 3 months of life with fat-free mass and fat mass percentage at 4 to 7 years of life. Body composition assessments by air displacement plethysmography and anthropometry were performed at term, at 3 months of corrected age, and at 4 to 7 years of age. Multiple linear regression analysis was used to observe the associations between body composition at these ages. At term, fat mass percentage showed a negative association and fat-free mass a positive association with fat-free mass at 4 to 7 years. The fat-free mass at 3 months and the gain in fat-free mass between term and 3 months showed positive associations with fat-free mass at 4 to 7 years.   Conclusion: Body composition at preschool age is associated with fat-free mass in the first 3 months of life, a sensitive period for the risk of metabolic diseases. What is Known: • Preterm infants have a deficit in fat-free mass and high adiposity at term equivalent age compared to full-term infants. • Fat-free mass reflects metabolic capacity throughout life and therefore is considered a protective factor against the risk of metabolic syndrome. What is New: •Fat-free mass gain in the first 3 months of corrected age is associated with fat-free mass at preschool and school ages. •The first 3 months of life is a sensitive period to the risk of metabolic diseases.

The trajectory of head circumference and neurodevelopment in very preterm newborns during the first two years of life: a cohort study.

OBJECTIVE: To evaluate the growth trajectory of head circumference and neurodevelopment, and to correlate head circumference with cognitive, language, and motor outcomes during the first two years. METHOD: Prospective cohort study in a tertiary hospital including 95 newborns under 32 weeks or 1500 g. Neonates who developed major neonatal morbidities were excluded. The head circumference was measured at birth, at discharge, and at term-equivalent age, 1, 3, 5, 12, 18, and 24 months of corrected age, and the Bayley Scales (Bayley-III) were applied at 12, 18 and 24 months of corrected age to assess cognitive, language and, motor domains. Scores below 85 were classified as mild/moderate deficits and scores below 70 as severe deficits. The association between head circumference Z score and Bayley scores was assessed using Pearson's correlation. The study considered a significance level of 0.05. RESULTS: There was a decrease of -0.18 in the head circumference Z score between birth and discharge and the catch-up occurred between discharge and 1 month (an increase of 0.81 in the Z score). There was a positive correlation between head circumference and Bayley scores at 18 months. There was also a positive correlation between head circumference at discharge and at 5 months with the three domains of the Bayley. CONCLUSION: Serial measurements of head circumference provide knowledge of the trajectory of growth, with early catch-up between discharge and 1 month, as well as its association with neurodevelopment. Head circumference is therefore a valuable clinical marker for neurodevelopment, especially in very preterm newborns.

Postnatal growth in small vulnerable newborns: a longitudinal study of 2 million Brazilians using routine register-based linked data.

BACKGROUND: Preterm, low-birth weight (LBW) and small-for-gestational age (SGA) newborns have a higher frequency of adverse health outcomes, including linear and ponderal growth impairment. OBJECTIVE: To describe the growth trajectories and to estimate catch-up growth during the first 5 y of life of small newborns according to 3 vulnerability phenotypes (preterm, LBW, SGA). METHODS: Longitudinal study using linked data from the 100 Million Brazilian Cohort baseline, the Brazilian National Live Birth System (SINASC), and the Food and Nutrition Surveillance System (SISVAN) from 2011 to 2017. We estimated the length/height-for-age (L/HAZ) and weight-for-age z-score (WAZ) trajectories from children of 6-59 mo using the linear mixed model for each vulnerable newborn phenotype. Growth velocity for both L/HAZ and WAZ was calculated considering the change (Δ) in the mean z-score between 2 time points. Catch-up growth was defined as a change in z-score > 0.67 at any time during follow-up. RESULTS: We analyzed 2,021,998 live born children and 8,726,599 observations. The prevalence of at least one of the vulnerable phenotypes was 16.7% and 0.6% were simultaneously preterm, LBW, and SGA. For those born at term, all phenotypes had a period of growth recovery from 12 mo. For preterm infants, the onset of L/HAZ growth recovery started later at 24 mo and the growth trajectories appear to be lower than those born at term, a condition aggravated among children with the 3 phenotypes. Preterm and female infants seem to experience slower growth recovery than those born at term and males. The catch-up growth occurs at 24-59 mo for males preterm: preterm + AGA + NBW (Δ = 0.80), preterm + AGA + LBW (Δ = 0.88), and preterm + SGA + LBW (Δ = 1.08); and among females: term + SGA + NBW (Δ = 0.69), term + AGA + LBW (Δ = 0.72), term + SGA + LBW (Δ = 0.77), preterm + AGA + LBW (Δ = 0.68), and preterm + SGA + LBW (Δ = 0.83). CONCLUSIONS: Children born preterm seem to reach L/HAZ and WAZ growth trajectories lower than those attained by children born at term, a condition aggravated among the most vulnerable.

Objective: to describe the follow-up of the preterm newborn in the third stage of the kangaroo method from the perspective of Primary Care nurses. Method: a qualitative, descriptive and exploratory study conducted in the basic health units of the city in the interior of Bahia, with nine nurses. The semi-structured interview and content analysis of Bardin were used. Results: nurses understand what a premature infant is superficially, but do not understand exactly how the Kangaroo Method works. Among the facilities, the help of Community Health Agents stand out, and the difficulties that prevailed most were the fragility in the reference and counter-reference. Final considerations: in view of this, it is evident the need for continuing education for nurses in Primary Care, the systematization of the third stage of the Method and professional training for nursing in order to improve information about the premature child, to disseminate knowledge that favors the service to this public.

Resultados en el neurodesarrollo en la edad preescolar y escolar de los recién nacidos pretérminos asistidos en el CTI neonatal de la Asociación Médica de San José / Neurodevelopmental preschool and school results of preterm newborns assisted at the neonatal ICU of the San José department medical provider in Uruguay / Resultados neuro desenvolvimento em idade pré-escolar e escolar de recém-nascidos pré-termos atendidos na UTI neonatal da assistência médica do departamento do São José no Uruguai

Uruguay acompaña la tendencia mundial al descenso de la natalidad con un descenso de la mortalidad concomitante, siendo la primera causa de mortalidad infantil la prematurez. Enfocados en la prematurez, es de nuestro interés conocer qué ocurre con estos niños luego del alta de la unidad neonatal. Se realizó el estudio de una cohorte de niños entre 4 y 8 años, nacidos con 32 semanas o menos de edad gestacional y/o con pesos al nacer de 1.500 g o menos, asistidos en su período neonatal en la Asociación Médica de San José, a quienes se les realizó el test de Battelle. Se logró identificar las áreas con mayor dificultad en el desarrollo para cada grupo de edad, concluyendo que se pueden realizar planes específicos de acción para promover el desarrollo de estos niños en la edad preescolar y escolar.

Uruguay follows the global declining trend in birth rates along with decreasing mortality, being prematurity the main cause of infant mortality. We studied premature children who had undergone the Battelle Test and had been discharged from the neonatal unit, a cohort of children between 4 and 8 years of age, born at 32 weeks or less of gestational age and/or having a birth weight of 1500g or less, assisted in their neonatal period at the San José Department Medical Center. We could identify the main areas affecting development for each age group, and concluded that specific action plans can be carried out to promote the development of these children at preschool and school age.

Realizamos um estudo de uma coorte de crianças entre 4 e 8 anos que tinham sido submetidas ao Teste de Battelle, nascidas com 32 semanas ou menos de idade gestacional e/ou com peso de nascimento igual ou inferior a 1500g, atendidas no período neonatal na Assistência Médica do Departamento de São José no Uruguai. Foi possível identificar as áreas de maior dificuldade de desenvolvimento para cada faixa etária, e concluir que podem se realizar planos de ação específicos para promover o desenvolvimento dessas crianças em idade pré-escolar e escolar.

Comparison of intergrowth-21st and Fenton curves for evaluation of premature newborns / Comparação das curvas de intergrowth-21st e de Fenton para avaliação de recém-nascidos prematuros

Abstract Objectives: to compare the intrauterine and postnatal growth of preterm infants according to the Intergrowth-21st and Fenton curves. Methods: study carried out in a maternity hospital, reference in high-risk pregnancy, with preterm infants born in 2018 who were hospitalized in the neonatal units of the institution. Preterm newborns weighed at least twice after birth were included in the sample and those that were syndromic, malformed or presented fluid retention were excluded. Proportions and means were compared using Pearson's chi-square and Student's t tests for paired samples, respectively. The McNemar test was used to compare categorical variables and the Kappa test to verify the degree of agreement between birth weight classifications obtained by the curves. Results: one hundred and fifty three infants with a median gestational age of 34.4 weeks were included. The incidences of the categories of nutritional status at birth did not differ between the curves. There was perfect agreement between the curves, except when newborns born under 33 weeks of gestational age were evaluated, in which case the agreement was substantial. About 21% of the babies classified as small for gestational age (SGA) by Intergrowth-21st were adequate for gestational age (AGA) according to Fenton and, on average, 20% of cases that had postnatal growth restriction (PNGR) according to Fenton standards were categorized as adequate weight by Intergrowth-21st. Postnatal weight classifications obtained by the evaluated curves had perfect agreement. Conclusions: the differences in theclassifications found between the charts reveal the importance of choosing the growth curve for monitoring preterm infants since behaviors based on their diagnoses can impact the life of this population.

Resumo Objetivos: comparar o crescimento intrauterino e pós-natal de prematuros segundo as curvas de Intergrowth-21st e Fenton. Métodos: estudo realizado em uma maternidade de referência em gestação de alto risco com prematuros nascidos em 2018 que ficaram internados nas unidades neonatais da instituição. Foram incluídos os pré-termos pesados em pelo menos dois momentos após o nascimento e excluídos aqueles sindrômicos, malformados ou com retenção hídrica. As proporções e médias foram comparadas a partir dos testes qui-quadrado de Pearson e t de student para amostras emparelhadas, respectivamente. Já o teste de McNemar foi utilizado para comparar as variáveis categóricas e teste Kappa para verificar o grau de concordância entre as classificações de peso ao nascer obtidos pelas curvas. Resultados: foram incluídos 153 lactentes com idade gestacional mediana de 34,4 semanas. As incidências das categorias de estado nutricional ao nascer não diferiram entre as curvas. Houve concordância perfeita entre as mesmas, exceto quando se avaliou os nascidos com menos de 33 semanas, onde a concordância foi substancial. Cerca de 21% dos bebês classificados como pequenos para a idade gestacional (PIG) por Intergrowth-21st foram adequados para idade gestacional (AIG) segundo Fenton e, em média, 20% dos casos que tiveram restrição de crescimento pós-natal (RCPN) de acordo aos padrões de Fenton foram categorizados com peso adequado por Intergrowth-21st. As classificações de peso pós-natal obtidas pelas curvas avaliadas tiveram concordância perfeita. Conclusões: as diferenças de classificação encontradas revelam a importância da escolha da curva de crescimento para monitorização de prematuros visto que, condutas baseadas em seus diagnósticos, podem impactar na vida dessa população.

Masaje de Field para la ganancia de peso en prematuros extremos. Estudio de viabilidad y aceptabilidad / Field massage for weight gain in extremely premature babies. Feasibility and acceptability study

Introducción: Una de las principales problemáticas del prematuro extremo es la limitación en su ganancia de peso debido a factores propios de su inmadurez (2,4); el desconocimiento acerca del tipo, el tiempo y la cantidad de estimulación que debe recibir, rescata la necesidad de indagar en nuevas intervenciones desde el cuidado de enfermería (4,11). Objetivo: Determinar la viabilidad y aceptabilidad de la terapia de masaje de Field, en prematuros extremos en una Unidad Neonatal de una institución de IV nivel, y los efectos en relación con la ganancia de peso. Metodología: Estudio cuantitativo, cuasi experimental, realizado en 15 prematuros extremos, que comparó el peso pre y post intervención, y un análisis para la estimación del efecto; se determinó la viabilidad del estudio mediante tasas de selección, reclutamiento y seguimiento y la aceptabilidad de la intervención en términos de satisfacción de los padres. El proceso de selección y reclutamiento se efectuó por más de 4 meses; la terapia se realizó 3 veces al día, durante 15 minutos, por 5 días consecutivos; posteriormente, se aplicó un cuestionario de aceptabilidad a las madres de los neonatos masajeados. Resultados: Se presentó una ganancia de peso significativa, lo cual podría ser atribuido al masaje, sin embargo, debe ser evaluado en futuras investigaciones frente a un grupo control. El estudio se hace menos viable en cuanto a la tasa de selección, si la muestra es captada durante poco tiempo, reduciendo la posibilidad de aplicar la intervención en una muestra significativa; en cuanto a reclutamiento y seguimiento, es totalmente viable. Es una terapia muy aceptada por las madres en términos de idoneidad, conveniencia y efectividad; sin embargo, se debe fortalecer desde sus riesgos y adherencia.

Introduction: One of the main problems of the extreme premature infants is the limitation in their weight gain due to factors inherent to their immaturity (2,4), the lack of knowledge about the type, the time, and the amount of stimulation they should receive, it also highlights the need to investigate new interventions in nursing care (4,11). Objective: To determine the feasibility and acceptability of Field's massage therapy in extreme premature infants in a Neonatal Unit of a level IV institution, and the effects in relation to weight gain. Methodology: Quantitative, quasi-experimental study, carried out in 15 extreme preterm infants, where pre and post intervention weight was compared, a analysis for effect estimation; the feasibility of the study was determined by selection, recruitment and followup rates and the acceptability of the intervention in terms of parental satisfaction. The selection and recruitment process were carried out for more than 4 months; the therapy was performed 3 times a day, for 15 minutes per session, for 5 consecutive days; subsequently, an acceptability survey was applied to the mothers of the massaged neonates who completed the intervention days. Results: here was a significant weight gain, which could be attributed to the massage, however, it should be evaluated in future research against a control group. The study becomes less viable in terms of the selection rate, if the sample is captured for a short time, reducing the possibility of applying the intervention in a significant sample; in terms of recruitment and follow-up, it is totally feasible. It is a therapy that is highly accepted by mothers in terms of suitability, convenience and effectiveness; however, it must be strengthened from its risks and adherence.

Complicaciones en la hemorragia intraventricular del recién nacido, a propósito de un caso / Complications in the intraventricular hemorrhage of the newborn, a propos of a case

RESUMEN La hemorragia interventricular es una complicación frecuente en el recién nacido prematuro. Se presentó el caso con el objetivo de describir las complicaciones en la hemorragia intraventricular en el recién nacido. Se trató de una recién nacida, producto de un embarazo de 30 semanas de gestación, con peso al nacer de 1 600 g. Desarrolló una hemorragia intraventricular e hidrocefalia que requirió diferentes intervenciones neuroquirúrgicas y desarrolló complicaciones sépticas graves. La ventriculitis y los abscesos cerebrales fueron las complicaciones más peligrosas. Se realizaron lavados ventriculares. Se utilizó antibióticos intraventriculares y también antibioticoterapia sistémica, cambios frecuentes de catéter de derivación al exterior y permanencia de una derivación ventricular externa por 102 días. Después de seis meses de evolución, de más de veinte intervenciones quirúrgicas, y de haber sufrido severas complicaciones sépticas, se logró realizar la derivación ventrículo-peritoneal definitiva, lográndose su egreso. Al año de vida, la paciente mantiene un desarrollo psicomotor adecuado (AU).

ABSTRACT The interventricular hemorrhage is a frequent complication in the premature newborn baby. The case was presente with the aim of describing the complications of intraventricular hemorrhage in the newborn baby. It dealed with a female newborn baby, product of a 30 weeks pregnancy, with weight at birth of 1 600 g. She developed intraventricular hemorrhage and hydrocephalus that required different neurosurgical interventions and developed serious septic complications. Ventriculitis and brain abscesses were the most dangerous complications. Ventricular lavages were performed. Intraventricular antibiotics were used as well as systemic antibiotic therapy, frequent changes of bypass catheter to the exterior and permanence of an external ventricular bypass for 102 days. And permanence of an external ventricular shunt for 102 days. After six months of evolution, more than twenty surgical interventions, and having suffered severe septic complications, it was possible to perform the definitive ventricular-peritoneal bypass, achieving her discharge. At a year of life, the patient maintains adequate psychomotor development (AU).

Clinical Results of the Implementation of a Breast Milk Bank in Premature Infants (under 37 Weeks) at the Hospital Universitario del Valle 2018-2020.

Breast milk is widely recognized as the best source of nutrition for both full term and premature babies. We aimed to identify clinical results of the implementation of a breast milk bank for premature infants under 37 weeks in a level III hospital. 722 neonates under 37 weeks, hospitalized in the Neonatal intensive care unit (ICU), who received human breast milk from the institution's milk bank 57% (n = 412) vs. mixed or artificial 32% (n = 229), at day 7 of life. An exploratory data analysis was carried out. Measures of central tendency and dispersion were used, strength of association of odds ratio (OR) and its confidence intervals (95% confidence interval (CI)). 88.5% had already received human milk before day 7 of life. Those who received human milk, due to their clinical condition, had 4 times a greater chance of being intubated (OR 4.05; 95% CI 1.80-9.11). Starting before day 7 of life decreases the opportunity to develop necrotizing enterocolitis by 82% (adjusted odds ratio (ORa) 0.18; 95% CI 0.03-0.97), intraventricular hemorrhage by 85% (ORa 0.15; 95% CI 0.06-0.45) and sepsis by 77% (ORa 0.23; 95% CI 0.15-0.33). Receiving human milk reduces the probability of complications related to prematurity, evidencing the importance that breast milk banks play in clinical practice.

Vertically transmitted infections and extrauterine growth restriction in preterm neonates: a new risk factor / Infecções de transmissão vertical e restrição do crescimento extrauterino em neonatos prematuros: novo fator de risco

Abstract Objectives: to investigate the association between Vertically Transmitted Infections (VTI) and Extrauterine Growth Restriction (EUGR) among premature infants in Neonatal Intensive Care Units (NICU). Methods: part of a large non-concurrent cohort study with medical records analysis. We evaluated EUGR in premature infants at a gestational age at birth of > 32 weeks and <36 weeks and presented a corrected gestational age of 36 completed weeks during a 27-day birth follow-up. Premature infants with major congenital anomalies were excluded. We analyzed associations among EUGR, VTI and covariables related to maternal disease, birth characteristics, perinatal morbidities and clinical practices. Results: out of the 91 premature infants, 59.3% (CI95%=48.9-69.0%) developed EUGR. VTI were observed in 4.4%o of the population; all premature infants affected by VTI had EUGR. The VTI found were syphilis, cytomegalovirus disease and toxoplasmosis. The final analysis has showed a positive association between VTI and EUGR (RR=1.57; CI95%o=1.07-2.30); the female covariables (RR=1.50; CI95%=1.11-2.02), moderate premature classification (RR=1.41; CI95%=1.06-1.87) and small for gestational age (RR=2.69; CI95% 1.853.90) have also influenced this outcome. Conclusion: this study revealed VTI as an important morbidity factor, with impact on the increased risk of EUGR between premature infants affected by these diseases.

Resumo Objetivos: investigar associação das Infecções de Transmissão Vertical (ITV) com a Restrição do Crescimento Extrauterino (RCEU) entre prematuros em Unidades de Terapia Intensiva Neonatal (UTIN). Métodos: recorte de um estudo de coorte não concorrente, com análise em prontuários. Avaliou-se a ocorrência de RCEU em prematuros que tiveram a idade gestacional de nascimento^ 32 semanas e < 36 semanas e que apresentaram idade gestacional corrigida de 36 semanas completas dentro do período de acompanhamento de 27 dias de vida.Foram excluídos os prematuros com anomalias congênitas maiores. Analisou-se associações entre RCEU, as ITV e as covariáveis relacionadas à doença materna, características do nascimento, morbidades perinatais e práticas clínicas. Resultados: dos 91 prematuros, 59,3% (IC95%o 48,9-69,0%o) desenvolveram RCEU. As ITVforam observadas em 4,4%o da população; todos os prematuros acometidos por ITV apresentaram RCEU. As ITV encontradas foram sífilis, citomegalovirose e toxoplasmose. A análise final demonstrou associação positiva das ITV com RCEU (RR=1,57; IC95%o= 1,072,30); as covariáveis sexo feminino (RR=1,50; IC95%o= 1,11-2,02), classificação prematuro moderado (RR=1,41; IC95%o=1,06-1,87) e pequeno para a idade gestacional (RR=2,69; IC95%1,85-3,90) também influenciaram este desfecho. Conclusão: este estudo revelou as ITV como importante fator de morbidade, com impacto no aumento do risco de RCEU entre prematuros acometidos por essas doenças.

Quality of complementary feeding and its effect on nutritional status in preterm infants: a cross-sectional study.

BACKGROUND: The first 2 years of life represent a critical phase for growth and development, with the quality of the diet at this stage having repercussions throughout adulthood. The present study aimed to develop an Index for Measuring the Quality of Complementary Feeding (IMQCF) for infants, as well as to evaluate diet quality and its effects on the nutritional status of preterm infants. METHODS: This cross-sectional study was conducted at a Brazilian University Hospital. The data were extracted by care protocol of outpatient preterm infants at 2 years of corrected age (CA). Dietary data were collected from 24-h recalls. The diet quality was assessed by the IMQCF composed of nine items based on a Brazilian Food Guide for children aged <2 years. Response options were scored 0-100, with scores closer to 100 representing a better quality diet. Association with growth indicators (Z-scores for weight- and length-for-age (WAZ and LAZ) were evaluated via tests of mean difference and multiple linear regression. RESULTS: The median complementary feeding (CF) score was 72.2 (61.1-77.8) A shorter breastfeeding duration or infant formula use and the early introduction of wheat-based foods, ultra-processed foods and cow's milk in the preterm's diet were the main factors interfering in the adequacy of diet. There was an association between the quality of the diet score and WAZ (0.44; 95% confidence interval = 0.03-0.85; P = 0.03). CONCLUSIONS: The introduction of poor quality food in the first 2 years of life interfered with the CF quality of preterm infants and can affect nutritional status at 2 years of CA, possibly in the long term.
