A decade of analysis describe of maternal and neonatal characteristics of live births in southern Brazil / Una década de descripción de las características maternas y neonatales de los nacidos vivos en el sur de Brasil

Introduction: Child health is conditioned by the circumstances of pregnancy, childbirth, and early life. Objective: To describe the maternal and neonatal characteristics of live births (LBs) in the Information System on Live Births of Santa Catarina (SC), Brazil. Materials and methods: A cross-sectional study describedthe maternal and neonatal characteristics of 940,059 LBs, from 2010 to 2019. Pearson's chi-square test and Fisher's exact test were conducted, with a statistical significance level of p < 0.05. Results: The mean values of maternal age, number of live children, and number of fetal deaths as well as abortions were 27.1 years, 0.9, and 0.2, respectively. The averages of the number of gestation weeks, number of prenatal consultations, the start date of the prenatal care, and birth weight were 38.5 weeks, 8.1 months, 2.5 monthsand 3,217.1 grams, respectively. Low birth weight (LBW) was prevalent among mothers without education (p < 0.001), including those without prenatal visits (p < 0.001). A higher prevalence of being underweight was observed among female neonates (p < 0.001) and with a maternal age of ≥ 40 years (10.8%; p < 0.001) compared to newborns with good vitality. Newborns with good vitality had a low prevalence of underweight (p < 0.001). The frequency of the variables studied increased, comparing the beginning and end of the period and whether the differences are statistically significant. Conclusions: The study draws attention to the need for interventions to improve the indicators that determine LBW(AU)

Renal deficit and associated factors in children born with low birth weight / Déficit renal e fatores associados em crianças nascidas com baixo peso

ABSTRACT Introduction: Kidney problems may be due to low birth weight alone or may occur in association with other conditions. The objective this study was to evaluate the association between maternal and birth characteristics, anthropometric measurements, and kidney function deficit in low birth weight infants. Methods: Cross-sectional study with children who were born weighing < 2500 grams and were under outpatient follow-up. Maternal factors investigated were prenatal care and presence of hypertension, diabetes, and infection during pregnancy. The children's variables were sex, gestational age, birth weight, Apgar score, use of nephrotoxic medications, age, body weight at the time of evaluation, height, and serum creatinine and cystatin C dosages. The glomerular filtration rate (GFR) was estimated with the combined Zapittelli equation. Multivariate logistic regression model was used for identification of associated factors, with renal function deficit (GFR < 60 mL/min/1.73 m2) as the dependent variable. Results: Of the 154 children evaluated, 34.42% had kidney function deficit. Most of them had a gestational age > 32 weeks (56.6%), a mean birth weight of 1439.7 grams, and mean estimated GFR of 46.9 ± 9.3 mL/min/1.73 m2. There was a significant association of GFR < 60 mL/min/1.73 m2 with children's current weight and use of nephrotoxic drugs. Discussion: Children born with low birth weight had a high prevalence of kidney function deficit and current normal weight was a protective factor while the use of nephrotoxic drugs during perinatal period increased the chance of kidney deficit. These findings reinforce the need to evaluate the kidney function in these children, especially those who use nephrotoxic drugs.

RESUMO Introdução: Problemas renais podem ser devido apenas ao baixo peso ao nascer ou podem ocorrer em associação com outras condições. O objetivo deste estudo foi avaliar a associação entre características maternas e de nascimento, medidas antropométricas e déficit da função renal em bebês de baixo peso ao nascer. Métodos: Estudo transversal com crianças que nasceram com peso < 2500 gramas e estavam sob acompanhamento ambulatorial. Os fatores maternos investigados foram cuidados pré-natal e presença de hipertensão, diabetes e infecção durante a gravidez. As variáveis das crianças foram sexo, idade gestacional, peso ao nascer, índice Apgar, uso de medicamentos nefrotóxicos, idade, peso corporal no momento da avaliação, altura e dosagens séricas de creatinina e cistatina C. A taxa de filtração glomerular (TFG) foi estimada com a equação combinada de Zapittelli. Utilizou-se um modelo de regressão logística multivariada para identificação de fatores associados, com déficit da função renal (TFG < 60 mL/min/1,73 m2) como variável dependente. Resultados: Das 154 crianças avaliadas, 34,42% apresentaram déficit da função renal. A maioria tinha idade gestacional > 32 semanas (56,6%), peso médio ao nascer de 1439,7 gramas, e TFG média estimada de 46,9 ± 9,3 mL/min/1,73 m2. Houve uma associação significativa da TFG < 60 mL/min/1,73 m2 com o peso atual das crianças e o uso de medicamentos nefrotóxicos. Discussão: Crianças nascidas com baixo peso apresentaram alta prevalência de déficit da função renal e o peso atual normal foi um fator de proteção, enquanto o uso de medicamentos nefrotóxicos durante o período perinatal aumentou a chance de déficit renal. Estes achados reforçam a necessidade de avaliar a função renal destas crianças, especialmente aquelas que usam medicamentos nefrotóxicos.

Prevalencia de osteopenia del prematuro antes y después de la implementación de una estrategia temprana de manejo fosfocálcico / Prevalence of osteopenia of prematurity before and after implementing an early strategy with the use of calcium and phosphate

Introducción. Con el uso de la nutrición parenteral agresiva en recién nacidos de muy bajo peso, se detectaron alteraciones del metabolismo fosfocálcico. En 2016 se implementó una estrategia de prevención a través del monitoreo fosfocálcico y su suplementación temprana. El objetivo fue estudiar si esta estrategia disminuye la prevalencia de osteopenia e identificar factores de riesgo asociados. Población y métodos. Estudio cuasiexperimental que comparó la prevalencia de osteopenia entre dos grupos: uno después de implementar la estrategia de monitoreo y suplementación fosfocálcica (01/01/2017-31/12/2019), y otro previo a dicha intervención (01/01/2013-31/12/2015). Resultados. Se incluyeron 226 pacientes: 133 pertenecen al período preintervención y 93 al posintervención. La prevalencia de osteopenia global fue del 26,1 % (IC95% 20,5-32,3) y disminuyó del 29,3 % (IC95% 21,7-37,8) en el período preintervención al 21,5 % (IC95% 13,6-31,2) en el posintervención, sin significancia estadística (p = 0,19). En el análisis multivariado, el puntaje NEOCOSUR de riesgo de muerte al nacer, recibir corticoides posnatales y el período de intervención se asociaron de manera independiente a osteopenia. Haber nacido luego de la intervención disminuyó un 71 % la probabilidad de presentar fosfatasa alcalina >500 UI/L independientemente de las restantes variables incluidas en el modelo. Conclusión. La monitorización y suplementación fosfocálcica precoz constituye un factor protector para el desarrollo de osteopenia en recién nacidos con muy bajo peso al nacer.

Introduction. With the use of aggressive parenteral nutrition in very low birth weight infants, alterations in calcium and phosphate metabolism were detected. In 2016, a prevention strategy was implemented through calcium phosphate monitoring and early supplementation. Our objective was to study whether this strategy reduces the prevalence of osteopenia and to identify associated risk factors. Population and methods. Quasi-experiment comparing the prevalence of osteopenia between two groups: one after implementing the calcium phosphate monitoring and supplementation strategy (01/01/2017­12/31/2019) and another prior to such intervention (01/01/2013­12/31/2015). Results. A total of 226 patients were included: 133 in the pre-intervention period and 93 in the post-intervention period. The overall prevalence of osteopenia was 26.1% (95% CI: 20.5­32.3) and it was reduced from 29.3% (95% CI: 21.7­37.8) in the pre-intervention period to 21.5% (95% CI: 13.6­31.2) in the post-intervention period, with no statistical significance (p = 0.19). In the multivariate analysis, the NEOCOSUR score for risk of death at birth, use of postnatal corticosteroids, and the intervention period were independently associated with osteopenia. Being born after the intervention reduced the probability of alkaline phosphatase > 500 IU/L by 71%, regardless of the other variables included in the model. Conclusion. Calcium phosphate monitoring and early supplementation is a protective factor against the development of osteopenia in very low birth weight infants.

Economic burden of healthcare-associated infection in low birth weight in-fants / 中国感染控制杂志

Objective To analyze the economic burden due to healthcare-associated infection(HAI)in low birth weight(LBW)infants,and provide theoretical basis for formulating HAI related policies.Methods The data of LBW infants in a tertiary first-class hospital from January 2018 to December 2022 were retrospectively collected.Propensity score matching method and marginal analysis were adopted to evaluate the economic losses in LBW in-fants and hospitals due to HAI.Results A total of 1 048 LBW infants were included in analysis,124 of whom had HAI,with HAI incidence of 11.8％.A total of 109 pairs were successfully matched using the propensity score matching method.The median length of hospital stay for LBW infants in the HAI group and non-HAI group were 34.0 and 11.0 days,respectively,the length of hospital extended 23 days in LBW infants in the HAI group(P＜0.001).The median hospitalization expenses for LBW infants in HAI group and non-HAI group were 38 067.6 and 12 375.7 Yuan,respectively,the hospitalization expense for LBW infants in HAI group was 25 691.9 Yuan more than non-HAI group(P＜0.001).The major increased expenses were examination,treatment and medication fees.The total hospitalization expenses in different birth weight LBW infants in HAI group were all higher than non-HAI group,and the differences were all statistically significant(all P＜0.05).LBW infants with gestational age＜32 weeks had longer length of hospital stay and higher total hospitalization expense,differences were all statistically significant(all P＜0.05).When the marginal profit ratios were 5％,10％,and 15％,respectively,the economic losses caused by HAI were 371 000 Yuan,742 000 Yuan,and 1 114 000 Yuan,respectively;The ratios of loss-profit and loss-profit to infection coefficient were 0.33 and 2.79,respectively.Conclusion HAI cause significant economic losses to both LBW infants and hospitals.Infants with a birth weight ≤1 000 g and those with a gestational age＜32 weeks are key populations for prevention and control.The lost-profit to infection coefficient can be used to estimate the economic loss of the hospital,timely adjust infection control measures,and reduce the incidence of HAI.

Evaluation of diagnostic efficacy and severity of necrotizing enterocolitis in premature infants by intestinal regional oxygen saturation and fecal calprotectin / 中国小儿急救医学

Objective:To evaluate the diagnostic value of intestinal regional oxygen saturation（rSO 2）and fecal calprotectin in the occurrence and severity of necrotizing enterocolitis（NEC）in premature infants. Methods:A prospective observational study was conducted among premature infants admitted to Quanzhou Children's Hospital from October 2019 to December 2022. Intestinal rSO 2 was monitored within two hours of diagnosis of NEC，and fecal calprotectin was measured. Results:A total of 60 patients were included, including 30 cases with NEC and 30 cases without NEC, 14 cases of medical NEC, 16 cases of surgical NEC, and eight infants died due to NEC. Infants with NEC had lower intestinal rSO 2 [49（30，60）% vs. 66（60，69）%] and higher calprotectin levels [479（297，886）μg/g vs. 203（113，275）μg/g] than those in infants without NEC ( P<0.01). The levels of intestinal rSO 2 were lower in surgical NEC than those in medical NEC，and were lower in the death group than that in the survival group ( P<0.01)，but no similar difference was found in the levels of calprotectin. ROC curve analysis showed that intestinal rSO 2 combined with calprotectin had a sensitivity of 73%，a specificity of 100%，and the largest area under curve of 0.91 in the diagnosis of NEC. Intestinal rSO 2 had an optimal cut-off value of 31% in predicting death in infants with NEC，with a sensitivity of 100%，a specificity of 95%，and an area under curve of 0.99. Conclusion:Intestinal rSO 2 and fecal calprotectin can effectively identify the presence of NEC，and their combined detection can improve the diagnostic efficiency. Intestinal rSO 2 is a good predictor of the severity of NEC，but not fecal calprotectin.

Energy Dense Feeding in Premature Infants and Its’ Associated Outcomes (Pemakanan Tumpat Tenaga dalam Bayi Pramatang dan Kesan Berkaitan) / Jurnal Sains Kesihatan Malaysia

@#COVID-19 infection in pregnant mothers is associated with higher risk of intrauterine growth retardation and premature births. Very low birth weight infants are more susceptible to neurodevelopmental and chronic respiratory problems. An infant delivered at 33 weeks via caesarean section to a COVID-19 Stage 5A positive mother, weighing 1.43kg at birth. She was kept nil by mouth with parenteral nutrition (PN) support since day five of life until referred to dietitian on day 22 of life for enteral nutrition (EN) establishment. Feeding was administered intermittently via oro-gastric Ryles tube. She was kept under non-invasive ventilation (NIV) mode and had difficulty in weaning from ventilation, leading to slow feeding progress. Initially, enteral trophic feeding was administered using premature infant formula fortified with modular products. In the later stage of feeding, modular products were tapered off and the formula was concentrated. Frequency of bowel output when using fortified formula is lesser compared to when using concentrated and supplemented formula. There is no significant difference in renal profile observed in both stages of feeding. Increasing energy intake using easily digestible sources is preferable as opposed to concentrating feeds even further due to concerns about osmolality and excess administration of other solutes. Intermittent bolus feeding mode may have an effect on dependency on oxygen since intermittent feeds can decrease tidal volume, minute ventilation and dynamic compliance. Additional research is necessary to establish optimal caloric density and nutritional compositions of feedings, feeding mechanisms and its’ effect on feeding tolerance.

Maternal mid-upper arm circumference as a predictor of low birth weight outcome among newborn deliveries of adolescents in a Tertiary Level Hospital

Background@#Maternal malnutrition is a major cause of low birth weight (LBW) newborn outcome especially among adolescent mothers. It is one of the key drivers of child stunting and initiates the vicious cycle of intergenerational malnutrition. The body mass index prior to pregnancy or at the initial trimester is currently being used to establish the desired weight gain throughout pregnancy. However, Filipino adolescents often delay their first antenatal visit at a later stage of pregnancy. Without a baseline weight, the establishment of appropriate weight gain and nutritional status is often challenging. Mid-upper arm circumference (MUAC) was proven to be a good proxy measure of acute malnutrition, however, there was no global consensus on what MUAC cut-off point to use to identify pregnant adolescents at risk for delivering LBW babies. Finding the optimal cut-off could facilitate early identification and intervention of pregnant adolescents who are nutritionally at risk and could eventually break the cycle of intergenerational malnutrition.@*Objectives@#The study aims to determine the association of maternal MUAC and the birth weight outcomes among newborn deliveries of adolescents in a tertiary hospital for a period of six months and to identify the optimal maternal MUAC cut-off point that can be used to predict low birth weight outcome among newborn deliveries of adolescents in a tertiary hospital. Methods. A cross-sectional study was conducted among adolescents ages 10 to 19 years who delivered babies in a tertiary hospital in the Philippines for a period of six months. Maternal MUAC and LBW outcome were documented, and their association was determined using a logistic regression analysis. To measure diagnostic accuracy, the sensitivity, specificity, and the area under the curve were taken for each MUAC point. A receiver operating characteristic (ROC) curve was used to aid the MUAC cut-off determination.@*Results@#Out of 237 newborn deliveries, 35% were noted with low birth weight while 65% had normal birth weight. Most of the mothers were in their late adolescence at 78%. The crude association for the MUAC cut-offs ≤23.00 cm, ≤23.50 cm, and ≤24.00 cm and LBW showed a significant value of 2.19, 2.25, and 2.39 at 95% CI, respectively. However, it is only the cut-off ≤24.00 cm that showed significant results for adjusted association by the logistic regression analysis. The MUAC cut-off ≤24.00 cm also showed a better trade-off value between the sensitivity and specificity. Furthermore, the optimal maternal MUAC measurement that predicts LBW newborn outcome points to ≤24.00 cm cut-off based on the ROC curve.@*Conclusion@#This study shows that the maternal MUAC is predictive of LBW outcome among adolescent deliveries.A MUAC cut-off of ≤24.00 cm was superior to lower cut-offs studied. The pregnant adolescents might need a higher MUAC cut-off than adults to allow timely intervention and prevention of poor neonatal outcomes. By doing this simple screening test, suspected pregnant adolescents can be easily identified and referred for further confirmatory testing.

Nursing care of an infant with severe bronchopulmonary dysplasia during the transition period from hospitalization to family / 中华护理杂志

To summarize the nursing care of a very low birth weight premature infant with severe type Ⅱbronchopulmonary dysplasia(BPD)during the transition period from hospitalization to home.The care of the infant was provided one-on-one by a BPD specialist nurse throughout the period.The key points of transitional care from hospitalization to home include:implementing tracheotomy and mechanical ventilation care to ensure stable blood oxygen saturation of the infant;providing nutritional support to improve the nutritional status of the infant;implementing step-by-step rehabilitation measures to improve the neuromotor development of the infant;implementing family integrated care to promote the primary caregivers of the infant to master nursing knowledge and skills;conducting personalized discharge follow-up with a multidisciplinary team to improve the quality of home care for this infant.After being hospitalized for 106 days,the infant was successfully discharged with a tracheotomy tube.At the age of 2 years and 6 months,a tracheotomy closure surgery was performed.After the surgery,the infant was able to breathe autonomously without symptoms of breathing difficulties and returned to normal family life.

Comparison of the short-term outcomes in very/extremely low birth weight infants supplemented with fortified donor human milk or preterm formula / 中华围产医学杂志

Objective:To compare the short-term outcomes of very low birth weight (VLBW) and extremely low birth weight (ELBW) infants supplementarily fed with fortified donor human milk (DHM) or preterm formula (PF) when the mother's own milk (MOM) is insufficient.Methods:This retrospective cohort study included 91 VLBW or ELBW preterm infants with birth weight<1 500 g who were hospitalized in Peking Union Medical College Hospital from October 1, 2017, to September 30, 2020. Based on the supplemental feeding method when MOM was insufficient, these infants were divided into the DHM group ( n=51) and PF group ( n=40). Mann-Whitney U, t-test, Chi-square test, or Fisher's exact test were used to compare the short-term clinical outcomes during hospitalization between the two groups. Results:(1) There were no statistically significant differences between the 91 preterm infants in the DHM group and PF group in their gestational age, birth weight, sex ratio, birth mode, mothers' age at delivery, or the proportion of infants of small gestational age (all P>0.05). (2) The feeding volume in the DHM group was significantly greater than that in the PF group on the 14th day after birth [(108.2±53.1) vs. (81.0±47.8) ml/(kg·d), t=0.78, P=0.020]. Moreover, the time to achieve the feeding amounts up to 120 ml/(kg·d) and 150 ml/(kg·d) for infants in the DHM group were significantly shorter than those in the PF group [(17.5±10.2) vs. (30.0±12.0) d, t=4.38; (22.1±13.3) vs. (32.3±11.9) d, t=0.02; both P<0.05]; (3) Lower proportion of peripherally inserted central catheter (PICC) [58.8% (30/51) vs. 100% (40/40), χ 2=21.88, P<0.001] and shorter PICC duration were observed in the DHM group [10.0 (0.0-19.0) vs. 29.0 (17.0-40.5) d, Z=5.56, P<0.001] compared to the PF group. The times of red blood cell transfusions and the incidence of late sepsis in the DHM group were less than those in the PF group [0.0 (0.0-2.0) vs. 2.0 (1.0-3.0) times, Z=4.44, P<0.001; 23.5% (12/51) vs. 50.0% (20/40), χ 2=6.39, P=0.011]. There were no statistically significant differences observed in the incidence of bronchopulmonary dysplasia, neonatal necrotizing enterocolitis, retinopathy of prematurity, and the length of hospitalization (all P>0.05). Conclusion:When MOM is insufficient, supplementing VLBW and ELBW infants with fortified donor human milk can shorten the time to achieve enteral nutrition and reduce the use rate and time of PICC, the incidence of late-onset sepsis, and the times of red blood cell transfusion.

Research progress in the pathogenesis of long-term chronic kidney disease associated with preterm birth and low birth weight / 中华围产医学杂志

With the development of neonatal intensive care, both the live birth rate and survival rate of preterm infants, especially in extremely preterm infants, have escalated. However, the long-term adverse prognosis of preterm infants became increasingly conspicuous. In the field of kidney disease, the existing clinical data have substantiated a higher susceptibility to chronic kidney disease (CKD) development during childhood or adulthood in preterm and low-birth-weight infants when compared with full-term infants. This suggests that preterm and/or low birth weight increases the risk for long-term CKD. Nonetheless, little attention has been paid to long-term CKD associated with preterm and/or low birth weight and the mechanism involved in this process is unknown. Current studies have suggested that reduced nephron and podocyte depletion are involved in this process, but detailed molecular mechanism remains inadequate. Therefore, this article reviews the research progress of long-term CKD correlated with preterm and/or low birth weight.

Effects of different fortified feeding methods on the nutrient metabolism and growth rate of very low birth weight preterm infants / 中国儿童保健杂志

【Objective】 To analyze the effects of different fortified feeding methods on nutritional metabolism and growth rate of preterm very low birth weight infants (VLBWI), in order to provide new clues for improving the prognosis of the preterm infants. 【Methods】 A total of 115 cases of premature VLBWI admitted to Department of Neonatology, The First Affiliated Hospital of Kunming Medical University from January 2019 to December 2020 were included in this study, and were divided into fortified breastfeeding group (HFM group), mixed feeding group, and premature formula feeding group (PF group) based on their feeding methods. The effects of different feeding methods on the nutritional metabolism and growth rate of premature VLBWI were analyzed. 【Results】 1) The hospitalization time of infants in the HFM group was shorter than that in PF group and mixed feeding group (t=7.185, 6.924, P<0.05). 2) The proportion of necrotizing enterocolitis (NEC) in the HFM group during hospitalization was lower than that in the PF group (P<0.05); the proportions of late onset septicemia(LOS) and extra uterine growth restriction(EUGR) in the HFM group during hospitalization were lower than those in the PF group (χ2=5.030, 4.147, P<0.05); the proportion of LOS was lower than that of the mixed feeding group(χ2=6.589, P<0.05). 3) During hospitalization, the proportions of abdominal distension, bloody stools and increased eosinophils in the HFM group were lower than those in the PF group (P<0.05), which in mixed feeding group was lower than those in PF group (Fisher exact test, P<0.05). 4) At discharge, the weight and length growth rate of the HFM group were higher than those of the mixed feeding group (t=3.722, 0.425, P<0.001) and the PF group (t =6.015, 0.496, P< 0.001). 【Conclusion】 Fortified breastfeeding can more effectively increase the growth rate of VLBWI in premature infants, improve nutritional metabolism, reduce complications and adverse feeding reactions related to premature infants, and is safer and more effective.

Les prématurés d'extrême faible poids de naissance, constituent un problème de santé publique dans les pays en voie de développement. L'étude avait pour objectif d'évaluer le pronostic immédiat des nouveau-nés de poids de naissance extrêmement faible hospitalisés à l'Hôpital Saint Camille de Ouagadougou (HOSCO). Methode : Il s'est agi d'une étude descriptive et analytique à collecte de données rétrospectives ayant porté sur les nouveau-nés de poids de naissance < 20ans (p=0,013) étaient les facteurs associés à la mortalité. Conclusion : La prise en charge des extrêmes poids de naissance reste difficile à cause des moyens très limités dans nos pays.Des interventions simples comme la mise en place d'un réseau de périnatalité, peuvent améliorer de manière considérable la survie de ces nouveau-nés.

Extremely low birth weight infants are a public health problem in developing countries. The objective of this study was to evaluate the prognosis of extremely low birth weight newborns hospitalized at Saint Camille Hospital in Ouagadougou (HOSCO). Method: This was a descriptive and analytical study with retrospective data collection on newborns with birth weight <1000g in the neonatology department from January 2017 to December 2021. Results: A total of 319 newborns were admitted giving a hospital frequency of 8.62%. Male sex was predominant with a sex ratio of 1.02. The mean age was 0.18 ± 0.71 days. The main signs on admission were hypothermia 88.40% and respiratory distress 92.16%. The evolution was marked by 92.79% of deaths of which 90.20% occurred during the early neonatal period. Hypothermia, birth outside HOSCO and maternal age less than 20 years were the factors associated with mortality. Conclusion: The management of low birth weight remains difficult because of the very limited resources in our countries. Simple and inexpensive interventions can considerably improve the survival of these newborns

Skin-to-skin contact and late-onset sepsis in newborns weighing up to 1.800g: a cohort study / Contato pele a pele e sepse tardia em recém-nascidos com peso até 1.800g: estudo de coorte

Abstract Objectives: to evaluate the association between the time to initiate the first skin-to-skin contact (SSC) and the daily practice time with the rates of late-onset sepsis in newborns ≤1,800g. Methods: a multicentric cohort study was carried out at the neonatal units located in three Brazilian geographic regions. The SSC time was recorded in individual files by the hospital staff and the newborn's parents. Maternal and neonatal data were obtained from medical records and through questionnaires applied to the mothers. Data analysis was carried out using a tree algorithm classification, which divided the data set into mutually exclusive subsets that best described the variable response. Results: 405 newborns participated in the study, with an average of 31.3 ± 2.7 weeks and 1,412g (QR=1,164-1,605g) as a median birth weight. The first SSC was carried out within 137 hours of life (≤5.7 days) was associated with a lower rate of late sepsis (p=0.02) for newborns who underwent daily SSC of 112.5 to 174.7 min/day (1.9 to 2.9h/day), with a reduction in the sepsis rate from 39.3% to 27.5%. Furthermore, the duration of SSC >174.7min/day (>2.9h/day) was relevant (p<0.001) for newborns who weighed >1,344g, with a reduction in this rate from 24.1% to 6%. Conclusions: SSP has been proven to be significant in reducing late-onset sepsis rates in preterm newborns, especially when carried out in a timely manner (≤5.7 days) and prolonged (>2.9h/day).

Resumo Objetivos: avaliar a associação entre o tempo para iniciar o primeiro contato pele a pele (CPP) e o tempo diário praticado com a taxa de sepse tardia em recém-nascidos ≤1.800g. Métodos: coorte multicêntrica realizada em unidades neonatais de três regiões geográficas brasileiras. O CPP foi registrado em ficha individual pela equipe e pais do recém-nascido. Dados maternos e neonatais foram obtidos por questionários aplicados às mães e em prontuários médicos. A análise dos dados foi realizada por algoritmo da árvore de classificação, que dividiu o conjunto de dados em subconjuntos mutuamente exclusivos que melhor descreveram a variável resposta. Resultados: 405 recém-nascidos participaram do estudo, com média de 31,3±2,7 semanas de idade gestacional e mediana de peso ao nascer 1.412g (IQ=1.164-1.605g). Realizar o primeiro CPP com até 137h de vida (≤5,7 dias) foi associado a menor taxa de sepse tardia (p=0,02) para recém-nascidos que fizeram CPP diário de 112,5 a 174,7 min/dia (1,9 a 2,9h/dia), com redução na taxa de sepse (39,3% para 27,5%). Além disso, a duração do CPP>174,7min/dia (>2,9h/dia) foi relevante (p<0,001) para os recém-nascidos >1.344g, com redução nesse desfecho (21,1% para 6%). Conclusões: o CPP mostrou-se importante para redução das taxas de sepse tardia em recém-nascidos pré-termo, especialmente quando realizado de forma oportuna (≤5,7 dias) e prolongada (>2,9h/dia).

Infección congénita por citomegalovirus en neonatos muy bajo peso / Congenital cytomegalovirus infection in very low birth weight neonates

Introducción: La infección congénita por el citomegalovirus en neonatos menores de 1500 gramos puede ser causa de morbilidad, mortalidad y discapacidad. Objetivo: Describir el comportamiento de la infección congénita por citomegalovirus en un servicio de neonatología. Métodos: Se realizó un estudio descriptivo y transversal con 61 neonatos. Se les realizó detección de citomegalovirus en la primera semana de vida en suero y orina, mediante reacción en cadena de la polimerasa, para determinar infección congénita. Se evaluaron variables perinatales en todos los neonatos, así como elementos clínicos y resultados de exámenes complementarios en los infectados. Resultados: La incidencia de infección congénita fue de un 10 por ciento (6/61). El 5 por ciento de los estudios fueron positivos (6/122). Ninguna muestra de orina resultó positiva (0/61) y en el 10 por ciento de las muestras de suero (6/61) se detectó el genoma del virus. Se encontró asociación entre valoración nutricional al nacer e infección por citomegalovirus (p< 0,05). El 83 por ciento de los neonatos infectados presentaron algún signo clínico y el síndrome de dificultad respiratoria fue el más frecuente (67 por ciento). En todos los neonatos con infección congénita el ultrasonido cerebral fue normal y en el 33 por ciento se detectó retinopatía de la prematuridad en el fondo de ojo. Conclusiones: La incidencia de infección congénita por citomegalovirus es alta en este grupo de riesgo. Los signos clínicos encontrados y los resultados del fondo de ojo en neonatos con infección congénita se relacionaron con la prematuridad y la valoración nutricional de hipotrófico se asoció con esta infección(AU)

Introduction: Congenital cytomegalovirus infection in neonates weighing less than 1500 grams can be a cause of morbidity, mortality, and disability. Objective: To describe the behavior of congenital cytomegalovirus infection in a neonatal service. Methods: A descriptive and cross-sectional study was conducted with 61 neonates. Cytomegalovirus was detected in the first week of life in serum and urine, by polymerase chain reaction, to determine congenital infection. Perinatal variables were evaluated in all neonates, as well as clinical elements and results of complementary examinations in infected infants. Results: The incidence of congenital infection was 10 percent (6/61). 5 percent of the studies were positive (6/122). No urine samples were positive (0/61) and the virus genome was detected in 10 percent of serum samples (6/61). An association was found between nutritional assessment at birth and cytomegalovirus infection (p < 0.05). A total of 83 percent of infected neonates had some clinical sign, with respiratory distress syndrome being the most common (67 percent). In all neonates with congenital infection, brain ultrasound was normal, and retinopathy of prematurity was detected in 33 percent of patients with fundus retinopathy. Conclusions: The incidence of congenital cytomegalovirus infection is high in this risk group. The clinical signs found and the results of the fundus in neonates with congenital infection were related to prematurity and the nutritional assessment of hypotrophic was associated with this infection(AU)

Third stage of the kangaroo method: exclusive breastfeeding and growth of preterm and/or low birth weight newborns / Terceira etapa do método canguru: aleitamento materno exclusivo e crescimento de recém-nascidos pré-termo e/ou de baixo peso ao nascer

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.

RESUMO Objetivo: Avaliar as taxas de aleitamento materno exclusivo e o crescimento dos recém-nascidos (RN) pré-termo e/ou de baixo peso ao nascer à alta da terceira etapa do Método Canguru (TEMC). Métodos: Estudo retrospectivo realizado em maternidade pública de referência entre janeiro/2014 e dezembro/2017, que incluiu os RN pré-termo (<37 semanas) e/ou de baixo peso (<2.500 g). As informações foram coletadas de prontuários médicos e analisadas pelo programa Statistical Package for the Social Sciences (SPSS). Resultados: Foram seguidos 482 RN, com mediana da idade gestacional de 33 semanas (variação: 24-39 sem) e peso ao nascer 1.715 g (variação: 455-2.830 g). O aleitamento materno exclusivo (AME) ocorreu em 336 (70,1%) RN à alta hospitalar e em 291 (60,4%) à alta da TEMC. Cada dia a mais de permanência hospitalar aumentou a chance do uso de fórmula infantil em 9,3% à alta hospitalar e em 10,3% à alta da TEMC. Permanecer na Unidade de Cuidados Intermediários Canguru (UCINCA) favoreceu o AME à alta hospitalar e da TEMC (p<0,001). Não realizar a Posição Canguru aumentou em 11% a chance de o RN utilizar fórmula infantil à alta hospitalar. O ganho de peso e crescimento do perímetro cefálico foram maiores nos RN em uso de fórmula infantil (p<0,001). Conclusões: O tempo de permanência hospitalar e a não realização da Posição Canguru favoreceram o uso de fórmula infantil à alta hospitalar e da TEMC. Permanecer na UCINCA favoreceu o AME à alta hospitalar e da TEMC. O ganho de peso e crescimento do PC foram maiores nos RN em uso de fórmula infantil.

Introducción: El parto prematuro y el bajo peso al nacer constituyen un problema de salud a escala mundial, ya que representan un predictor importante del desarrollo y crecimiento posnatal, así como un indicador de morbilidad y mortalidad infantil. Objetivo: Caracterizar a madres con recién nacidos prematuros y de bajo peso según variables clínicas y epidemiológicas. Métodos: Se realizó un estudio descriptivo, de corte transversal, desde enero hasta diciembre de 2022, de 35 madres con recién nacidos prematuros y de bajo peso, pertenecientes al Policlínico Docente Área Este de la ciudad de Camagüey. Entre las variables analizadas figuraron: edad, estado nutricional, clasificación del riesgo, control prenatal, riesgo reproductivo preconcepcional, consulta multidisciplinaria, enfermedades propias del embarazo, estado al nacer, deficiencias detectadas y causas. Resultados: En la serie predominaron el grupo etario de 35 y más años (25,7 %), la obesidad (37,1 %), las madres con elevados riesgos (45,7 %), quienes recibieron entre 8-14 controles prenatales, y malos antecedentes obstétricos (31,4 %). Por otra parte, 22,9 % de las madres tuvieron hijos con bajo peso y 31,4 %, prematuros; en tanto, hubo dificultades en el seguimiento por ausencias (57,1 %). Conclusiones: Las madres presentaron características clínicas y epidemiológicas desfavorables, tales como la edad de 35 y más años, la obesidad, el alto riesgo, los malos antecedentes obstétricos y la infección vaginal como enfermedad propia del embarazo, que influyeron en que los neonatos fueran prematuros o de bajo peso, o ambos.

Introduction: Preterm birth and low birth weight constitute a health problem worldwide, since they represent an important predictor of development and postnatal growth, as well as an indicator of newborn morbidity and mortality. Objective: To characterize mothers with preterm and low weight infants according to clinical and epidemiological variables. Methods: A descriptive, cross-sectional study was carried out from January to December, 2022, of 35 mothers with preterm and low weight infants, belonging to the East Area Teaching Polyclinic in Camagüey city. Age, nutritional state, risk classification, prenatal control, preconcepcional reproductive risk, multidisciplinary visits, diseases characteristic of pregnancy, birth state, detected deficiencies and causes were among the analyzed variables. Results: In the series there was prevalence of the 35 and over age group (25.7%), obesity (37.1%), high risk mothers (45.7%) who received among 8-14 prenatal controls, and bad obstetric history (31.4%). On the other hand, 22.9% of the mothers had low weight children and 31.4% preterm children; as long as there were difficulties in follow up due to absences (57.1%). Conclusions: The mothers presented unfavorable clinical and epidemiological characteristics, such as the 35 and over years, obesity, high risk, bad obstetric history and vaginal infection as a disease characteristic of pregnancy, which influenced the infants to be preterm or low weight, or both.

Prevalencia de la arteria umbilical única en gestantes: su relación con otras malformaciones y el bajo peso al nacer

Introducción: La arteria umbilical única tiene una incidencia del 1 % en los recién nacidos. Se le asocia frecuentemente con gemelaridad, malformaciones y crecimiento intrauterino retardado, y constituye un factor de riesgo de prematuridad, muerte fetal y neonatal. Objetivos: Determinar la prevalencia de la arteria umbilical única en gestantes, y la asociación de esta entidad con otras malformaciones y el bajo peso al nacer. Materiales y métodos: Estudio descriptivo retrospectivo, con datos obtenidos de las historias clínicas y del modelo de seguimiento lineal existente en las consultas de genética comunitaria del municipio Matanzas, de enero de 2015 a diciembre de 2019. Resultados: La prevalencia de la arteria umbilical única fue del 0,3 %. Las malformaciones más frecuentes fueron las renales; el 27,7 % de los nacimientos fueron pretérmino y el 33,3 % de los nacidos fue con un peso inferior a 2500 g. Conclusiones: La arteria umbilical única constituye un marcador para otras malformaciones. Cuando coexisten ambas existe riesgo de prematuridad y bajo peso al nacer. Se recomienda realizar examen clínico posnatal a todo recién nacido con arteria umbilical única, pesquisando defectos renales y cardíacos.

Introduction: The single umbilical artery has an incidence of 1% in newborns. It is frequently associated with twinning, malformations and delayed intrauterine growth, and is a risk factor of prematurity, fetal and neonatal death. Objective: To determine the prevalence of single umbilical artery in pregnant women and the association of this entity with other malformations and low birth weight. Materials and methods: Retrospective descriptive study, with data obtained from medical records and the linear follow-up model existing in the community genetic clinics of the municipality of Matanzas, from January 2015 to December 2019. Results: The prevalence of the single umbilical artery was 0.3%. The most frequent malformations were renal ones; 27.7% of births were pre-term and 33.3% of those born weighed less than 2500g. Conclusions: The single umbilical artery is a marker for other malformations. When both coexist there is a risk of prematurity and low birth weight. Postnatal clinical examination is recommended for all newborns with single umbilical artery, checking for renal and heart defects.

Costo-efectividad de la calidad del control prenatal con respecto al bajo peso al nacer en el Cauca / Antenatal control quality cost-effectiveness regarding low birth weight in Cauca

Antecedentes: El departamento del Cauca en Colombia es multiétnico, multicultural y biodiverso, también con grandes diferencias en bajo peso al nacer (BPN), mortalidad perinatal y mortalidad neonatal tardía entre municipios. Objetivo: Determinar la relación de costo-efectividad del control prenatal (CPN) cuando ha tenido buena calidad frente al que ha tenido calidad deficiente con respecto al BPN en el departamento del Cauca entre 2018 y 2020. Método: Evaluación económica con diseño epidemiológico de una cohorte histórica desde la perspectiva de la institución pagadora. Se calculó la razón incremental de costo-efectividad (RICE), análisis de sensibilidad e impacto presupuestal. Resultados: La incidencia de BPN fue del 8,3% (348/4182). La calidad deficiente en el CPN incrementó el riesgo de BPN (OR: 3,38; IC95%: 1,05-8,2) y la buena calidad tuvo una mejor relación de costo-efectividad (RICE: USD 2727,75), con posición dominante frente a la calidad deficiente (6,14 veces el PIB per cápita de ahorro) y con un impacto presupuestal de USD 2.904.392. Conclusiones: La buena calidad del CPN en el departamento del Cauca durante 2018-2020 fue costo-efectiva y dominante por ser de menor costo y mayor efectividad.

Background: The department of Cauca in Colombia is multiethnic, multicultural, and biodiverse, also with large differences in low birth weight (LBW), perinatal mortality, and late neonatal mortality among municipalities. Objective: To determine the cost-effectiveness relationship of antenatal care (ANC) when it has had good quality compared to that which has had poor quality with respect to low birth weight in the department of Cauca between 2018 and 2019. Method: Economic evaluation with epidemiological cohort design historical from the perspective of the payer institution. Incremental cost-effectiveness ratio (RICE), sensitivity analysis, and budgetary impact were calculated. Results: The incidence of LBW was 8.3% (348/4182). Poor quality in ANC increased the risk of LBW (OR: 3.38; CI95%: 1.05-8.2), good quality had a better cost-effectiveness ratio (RICE: USD 2727.75), with dominant position against poor quality (6.14 times the GDP/capita savings) with a budgetary impact of USD 2,904,392. Conclusions: The good quality of the ANC in the department of Cauca during 2018-2020 was cost-effective and dominant because it is lower cost and more effective.
