RESUMO
This comprehensive review thoroughly examines the historical evolution, physiological foundations, and contemporary advancements in the application of phototherapy for neonatal hyperbilirubinemia. Neonatal hyperbilirubinemia, a common condition resulting from the immature hepatic processes in newborns, poses potential risks, including neurotoxicity, if left untreated. The review traces the historical progression from early recognition of neonatal jaundice to the development of various phototherapy modalities, showcasing the dynamic landscape of neonatal care. Emphasizing the physiological intricacies of bilirubin metabolism in neonates, the study underscores the vulnerability of newborns to hyperbilirubinemia due to delayed hepatic maturation. Phototherapy is a cornerstone in managing hyperbilirubinemia, demonstrating consistent efficacy in reducing unconjugated bilirubin levels. The implications for clinical practice are significant, offering healthcare professionals insights into tailoring treatment strategies based on individual neonatal characteristics and the severity of jaundice. Integrating advanced monitoring and control systems enhances the precision and safety of phototherapy. Recommendations for future research emphasize the need to investigate long-term outcomes, explore adjunctive therapies, and address resource limitations to ensure global access to effective neonatal care. Overall, this review contributes to the ongoing refinement of neonatal care practices, offering a comprehensive understanding of neonatal hyperbilirubinemia and its evolving treatment landscape.
RESUMO
Hemolytic disease of the fetus and newborn (HDFN) may cause severe cholestasis with direct bilirubin concentrations reaching up to 50 times the upper limit of normal. This case report describes twins whose highest direct bilirubin concentrations were 32.2 mg/dL and 50.2 mg/dL, with no significant signs of hepatic impairment. The index pregnancy was complicated by Rhesus factor immunization with anti-D antibodies present in maternal serum, which caused fetal anemia requiring intrauterine blood transfusions. Complementary tests demonstrated Rhesus D alloimmunization as the sole cause of cholestasis. To the best of our knowledge, this is the first study to describe such elevated direct bilirubin concentrations caused by HDFN.
RESUMO
Objectives: Jaundice occurs in 60% of full-term and 80% of pre-term newborns. This study compared the effect of phototherapy with and without phenobarbital on icteric newborns. Materials & Methods: This study is a randomized clinical trial conducted from July until March 2018 at Imam Reza Hospital, Mashhad University of Medical Science, Iran. Full-term and near-term neonates with more than 2000 grams who were hospitalized in the mentioned period for jaundice were entered into the study. The newborns were divided into two groups using block randomization. Data were analyzed by SPSS version 19. Results: The average gestational age was 36.4 weeks (SD 2.39) in the intervention group and 36.9 weeks (SD 2.16) in the control group, with no significant difference between them. The mean hospital stay for the intervention group was 72 hours (SD 1.66), compared to 55 hours (SD 1.88) for the control group. At discharge, the serum bilirubin level in the intervention group was 11.53 mg/dL (SD 0.77), while it was 10.80 mg/dL (SD 1.09) in the control group, a statistically significant difference. Conclusion: According to this study, phototherapy with phenobarbital is not more effective than phototherapy alone in neonatal hyperbilirubinemia.
RESUMO
Hypoparathyroidism is the most common endocrinological feature in children with Sanjad-Sakati syndrome. Treatment includes active vitamin D and calcium supplementation. Here, we report a case of a newborn with Sanjad-Sakati syndrome who had severe hypocalcemia since birth who responded to PTH subcutaneous pump infusion. The child was born at 35 weeks with hypocalcemia since the first day of life. The standard medical treatment proved ineffective for the newborn, necessitating the administration of unusually high doses of oral and IV calcium and vitamin D analogue for a 2 months. As a result, intermittent subcutaneous injections of PTH were commenced, resulting in an initial improvement in calcium levels, although this proved to be short-lived. Subsequently, a switch to continuous infusion via a Medtronic Vio pump was made, which unfortunately resulted in iatrogenic hypercalcemia, requiring management of hypercalcemia. Later, calcium carbonate and alfacalcidol were resumed at a lower dosage and continued to have average requirements for patients with hypoparathyroidism. PTH subcutaneous infusion can be highly effective in refractory hypocalcemia cases and can significantly impact the treatment course and facilitate hospital discharge as seen in our case. Careful dosage and monitoring are required to avoid iatrogenic hypercalcemia.
RESUMO
BACKGROUND: Neonates have an increased risk of vitamin D insufficiency due to the inadequate supplementation of mothers and infants after birth. Insufficiency of vitamin D is frequently detected in critically ill patients and is associated with disease severity and mortality. There is yet to be a consensus on the appropriate regimen of vitamin D3 supplementation in high-risk infants. AIM: The main objectives of this study were to determine the prevalence of vitamin D insufficiency in neonates with severe comorbidities and to evaluate whether high-dose vitamin D3 oral administration leads to normal plasmatic concentrations without side effects. METHODS: The current study was a randomized, prospective trial of 150 patients admitted to the Neonatal Intensive Care Unit (NICU) at Maria Sklodowska Curie Emergency Children's Hospital in Bucharest. Patients were divided into three subgroups based on the chronological order of their admission date. Each subgroup received a different pharmaceutical product of vitamin D3. We administered a dosage of 10,000 IU/kg of vitamin D3 orally in three steps, as follows: at admission, one week after admission, and one month from the first administration, targeting a serum 25-hydroxyvitamin D concentration of at least 40 ng/mL. RESULTS: Most neonates (68%) achieved an optimum vitamin D level after one month, even though only 15% of patients had an optimum concentration at admission. After the first high dose of vitamin D3, there was a 27% increase in the mean vitamin D plasmatic level compared to admission levels. However, after one month, the concentrations decreased in all subgroups due to the gap of three weeks between the last two administrations. CONCLUSIONS: An intermittent, weekly high-dose vitamin D3 oral administration leads to a steadier increase and normalization of vitamin D concentration in most critically ill neonates. However, high-dose vitamin D3 administered orally after three weeks decreases vitamin D levels in this high-risk population.
RESUMO
Introduction: We aimed to analyse the outcomes of hyperbaric oxygen treatment (HBOT) and describe difficulties encountered in infants, a rare patient population in this therapeutic intervention, with limited scientific reports. Methods: This was a retrospective analysis of patients 12 months old or younger who underwent HBOT in two different institutions. Demographic data, clinical presentation, HBOT indication, chamber type, oxygen delivery method, total number of treatments, outcome and complications were extracted from clinical records. Results: There were 54 infants in our study. The patients' median age was 3.5 (range 0-12) months. The major HBOT indication was acute carbon monoxide intoxication (n = 32). A total of 275 HBOT treatments were administered, mostly performed in multiplace chambers (n = 196, 71%). Only one patient (2%) required mechanical ventilation. Acute signs were fully resolved in the most patients (n = 40, 74%). No complications related to HBOT were reported. Conclusions: This study suggests that HBOT may be a safe and effective treatment for infants. Paediatricians should consider HBOT when indicated in infants even for the preterm age group.

Preclinical evidence suggests that inter-individual variation in the structure of the hypothalamus at birth is associated with variation in the intrauterine environment, with downstream implications for future disease susceptibility. However, scientific advancement in humans is limited by a lack of validated methods for the automatic segmentation of the newborn hypothalamus. N = 215 healthy full-term infants with paired T1-/T2-weighted MR images across four sites were considered for primary analyses (mean postmenstrual age = 44.3 ± 3.5 weeks, nmale /nfemale = 110/106). The outputs of FreeSurfer's hypothalamic subunit segmentation tools designed for adults (segFS) were compared against those of a novel registration-based pipeline developed here (segATLAS) and against manually edited segmentations (segMAN) as reference. Comparisons were made using Dice Similarity Coefficients (DSCs) and through expected associations with postmenstrual age at scan. In addition, we aimed to demonstrate the validity of the segATLAS pipeline by testing for the stability of inter-individual variation in hypothalamic volume across the first year of life (n = 41 longitudinal datasets available). SegFS and segATLAS segmentations demonstrated a wide spread in agreement (mean DSC = 0.65 ± 0.14 SD; range = {0.03-0.80}). SegATLAS volumes were more highly correlated with postmenstrual age at scan than segFS volumes (n = 215 infants; RsegATLAS 2 = 65% vs. RsegFS 2 = 40%), and segATLAS volumes demonstrated a higher degree of agreement with segMAN reference segmentations at the whole hypothalamus (segATLAS DSC = 0.89 ± 0.06 SD; segFS DSC = 0.68 ± 0.14 SD) and subunit levels (segATLAS DSC = 0.80 ± 0.16 SD; segFS DSC = 0.40 ± 0.26 SD). In addition, segATLAS (but not segFS) volumes demonstrated stability from near birth to ~1 years age (n = 41; R2 = 25%; p < 10-3 ). These findings highlight segATLAS as a valid and publicly available (https://github.com/jerodras/neonate_hypothalamus_seg) pipeline for the segmentation of hypothalamic subunits using human newborn MRI up to 3 months of age collected at resolutions on the order of 1 mm isotropic. Because the hypothalamus is traditionally understudied due to a lack of high-quality segmentation tools during the early life period, and because the hypothalamus is of high biological relevance to human growth and development, this tool may stimulate developmental and clinical research by providing new insight into the unique role of the hypothalamus and its subunits in shaping trajectories of early life health and disease.

Human milk odor is attractive and appetitive for human newborns. Here, we studied behavioral and heart-rate (HR) responses of 2-day-old neonates to the odor of human colostrum. To evaluate detection in two conditions of stimulus delivery, we first presented the odor of total colostrum against water. Second, the hedonic specificity of total colostrum odor was tested against vanilla odor. Third, we delivered only the fresh effluvium of colostrum separated from the colostrum matrix; the stability of this colostrum effluvium was then tested after deep congelation; finally, after sorptive extraction of fresh colostrum headspace, we assessed the activity of colostrum volatiles eluting from the gas chromatograph (GC). Regardless of the stimulus-delivery method, neonates displayed attraction reactions (HR decrease) as well as appetitive oral responses to the odor of total colostrum but not to vanilla odor. The effluvium separated from the fresh colostrum matrix remained appetitive but appeared labile under deep freezing. Finally, volatiles from fresh colostrum effluvium remained behaviorally active after GC elution, although at lower magnitude. In sum, fresh colostrum effluvium and its eluate elicited a consistent increase in newborns' oral activity (relative to water or vanilla), and they induced shallow HR decrease. Newborns' appetitive oral behavior was the most reproducible response criterion to the effluvium of colostrum. In conclusion, a set of unidentified volatile compounds from human colostrum is robust enough after extraction from the original matrix and chromatographic processing to continue eliciting appetitive responses in neonates, thus opening new directions to isolate and assay specific volatile molecules of colostrum.

Background: Paternal involvement during pregnancy has been shown to have a positive impact on the mother-baby dyad during and after birth. The presence of the father during birth also positively influences father-child attachment, reduces, apprehension, and stress, increases maternal satisfaction, and increases love and respect for the partners. This study explored the experiences of fathers who were present in the delivery room during the delivery process. Methods: This qualitative content analysis study was conducted at a maternity hospital in Kingston, Jamaica from June to July 2022. A total of ten (10) fathers of babies delivered within six weeks were purposefully selected to be interviewed via telephone over four weeks. Data were analysed using a thematic approach. Results: Four sub-themes and one theme were extracted from data analysis. Fathers perceived satisfaction and empowerment in the shadow of positive and negative feelings as the theme. Sub-themes emerged from the data including "clinician's acceptance and support", "close bonding and attachment with mother and baby", "preparedness of fathers to give support", and "inspiring and amazing feeling by fatherhood experiences". Conclusion: Fathers experienced the feeling of empowerment and wished to take up their role during the delivery of their newborns. Their experiences were influenced by the midwives and the resources available to support their accommodation. More policies are needed to strengthen the fathers' involvement during antenatal clinic visits, delivery, and postnatal care.

Low birth weight is a newborn delivered with birth weight of less than 2500 g regardless of gestational age is called. It is a significant issue affecting over 30 million infants worldwide. Thus, the study determine factors associated with low birth weight among newborns delivered at Mettu Karl Comprehensive Specialized Hospital, Southwest Ethiopia. A facility-based case-control study was conducted with 336 newborns (112 cases and 224 controls) from September 12 to December 23, 2022. The study population was newborns with birth weights of 2500 g to 4000 g as controls and newborns with birth weights < 2500 g were cases. Simple random sampling techniques were used to recruit study participants with a ratio of 1 to 3 cases to controls, respectively. Data was collected by interviews and a checklist. Data were entered and analysed using SPSS version 23. Binary and multivariate logistic regression analyses were computed to identify factors associated with low birth weight, a p-value less than 0.05 was used to declare the strength of statistical significance. A total of 327 newborns were contacted, yielding a 97% response rate. MUAC < 23 cm (AOR = 2.72, 95% CI 1.24 to 6.19), inadequate diet diversification (AOR = 4.19, 95% CI 2.04 to 8.60), lack of iron and folic acid supplementation (AOR = 2.94, 95% CI 1.25 to 6.88), history of hypertension (AOR = 2.55, 95% CI 1.09 to 6.00), and lack of nutritional counselling (AOR = 4.63, 95% CI 2.22 to 9.64) were determinants of low birth weight. Low birth weight is linked to residence, maternal MUAC, hypertension history, and ANC visit. Lifestyle modifications, early detection, management, and nutrition information can reduce risk.

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.

Objective: This report summarizes the key discussions from the "Early Care (0-3 years) in Duchenne Muscular Dystrophy" meeting, which aimed to address the challenges and opportunities in the diagnosis and care of Duchenne muscular dystrophy (DMD) and female carriers within the 0-3-year age group. Methods: The meeting brought together experts and healthcare providers who shared insights, discussed advancements in DMD care, and identified research needs. Presentations covered diagnostic challenges, approved therapies, clinical trials, identification of young female carriers, and the importance of clinical care and support for families. Results: The meeting highlighted the importance of timely diagnosis and the lack of evidence-based guidelines for the care of children with DMD aged 0-3 years. Diagnostic challenges were discussed, including delays in receiving a DMD diagnosis and disparities based on ethnicity. The potential benefits and process of newborn screening were addressed.Approved therapeutic interventions, such as corticosteroids and exon-skipping drugs, were explored, with studies indicating the potential benefits of early initiation of corticosteroid therapy and the safety of exon-skipping drugs in DMD. Clinical trials involving infants and young boys were discussed, focusing on drugs like ataluren, vamorolone, and gene therapies.The meeting emphasized the importance of clinical care and support for families, including comprehensive information provision, early intervention services, and individualized support. The identification and care of young female carriers were also addressed. Conclusion: The meeting provided a platform for experts and healthcare providers to discuss and identify key aspects of early care for children with DMD aged 0-3 years. The meeting emphasized the need for early diagnosis, evidence-based guidelines, and comprehensive care and support for affected children and their families. Further research, collaboration, and the development of consensus guidelines are needed to improve early diagnosis, treatment, and outcomes in this population.

BACKGROUND: Reducing mother-infant separation in early life is a key breakthrough in the care improvement model in the neonatal intensive care unit (NICU). Previously, we reported effect of family integrated care (FICare) on clinical outcomes of preterm infants. We further clarify effect of FICare on maternal stress. METHODS: Mothers of preterm infants at eleven NICUs were randomized to the FICare group and the control group. The primary outcome was the reduction in Parental Stress Scale: NICU (PSS:NICU) score from enrollment to discharge. RESULTS: Total of 601 mothers (298 in FICare and 303 in control groups) enrolled. There was no significant difference in PSS:NICU score between the 2 groups at enrollment (P = 0.824), and the FICare group had lower scores at discharge (P < 0.001). PSS:NICU scores of both groups were significantly decreased at discharge compared to at enrollment (P < 0.001), and the reduction was greater in the FICare group (P < 0.001). After applying linear regressions to adjust for potential confounders, results remained unchanged (adjusted P < 0.001). PSS:NICU score reductions from enrollment to discharge were positively correlated with maternal age in the control group (ρ = 0.147, P = 0.011). LIMITATIONS: This study was limited to post-hoc analyses and did not include follow-up to evaluate long-term effects. CONCLUSIONS: FICare is helpful for reducing maternal stress in preterm infants in the NICU. Older mothers tend to have limited improvements in stress after traditional nonparent care, which suggests that they may benefit more from the FICare model.

RESUMO
Contexte et objectifs. L'ictère néonatal est un symptôme fréquent. L'objectif de la présente étude était d'actualiser le profil épidémiologique et d'identifier les facteurs associés à l'ictère néonatal chez les nouveau-nés malades. Méthodes. Une étude transversale descriptive a été menée de juin 2022 à avril 2023 aux Cliniques Universitaires de Kinshasa. L'étude a concerné les nouveau-nés malades ayant présenté un ictère cutanéomuqueux. Les variables sociodémographiques, périnatales, cliniques et paracliniques ont été recherchées. Résultats. Sur 152 nouveau-nés malades, 102 (67,1%) cas d'ictère ont été identifiés. Les nouveau-nés à terme (72,5%), nés par voie basse (67,6%) et dont les mères avaient présenté des infections uro-génitales (98%) et de groupe sanguin O (53%) rhésus positif (97,1%) étaient les plus représentés. L'ictère s'est manifesté dans la première semaine de vie (85,3 %). La bilirubine sérique totale initiale se situait entre 10 et 15 mmol/L (57,8 %). L'origine infectieuse était notée dans 85 % des cas (Klebsiella pneumoniae dans 50 % des cas). La photothérapie conventionnelle a été utilisée chez 74,5 %. L'accouchement par voie basse était le seul facteur associé (p=0,001). Conclusion : L'ictère néonatal est fréquent chez les nouveau-nés malades. L'étiologie infectieuse doit être recherchée systématiquement. Une prise en charge appropriée permet de réduire la survenue de séquelles neurosensorielles.
Context and objective. Neonatal jaundice is a common symptom. The objective of the present study was to update the epidemiological profile and identify the factors associated with neonatal jaundice in sick newborns. Methods. A descriptive cross-sectional study was conducted from June 2022 to April 2023 at the Kinshasa University Hospital. The study included sick newborns who presented with mucocutaneous jaundice. Sociodemographic, perinatal, clinical and paraclinical variables were sought. Results. Out of 152 sick newborns, 102 (67.1 %) cases of jaundice were identified. Fullterm newborns (72.5 %), born vaginally (67.6 %) and whose mothers had presented with urogenital infections (98 %) and blood group O (53 %) rhesus positive (97.1 %) were the most represented. Jaundice appeared in the first week of life (85.3 %). Baseline total serum bilirubin was between 10 and 15 mmol/L (57.8 %). The infectious origin was noted in 85 % of cases (Klebsiella pneumoniae in 50 % of cases). Conventional phototherapy was used in 74.5 %. Vaginal delivery was the only associated factor (p=0.001). Conclusion. Neonatal jaundice is common in sick newborns. The infectious etiology must be systematically sought. Appropriate management helps reduce the occurrence of neurosensory aftereffects.

Abstract Introduction The study of the diaphragm muscle has aroused the interest of physiotherapists who work with kinesiological ultrasonography, but still little explored; however, its findings can contribute to the clinical practice of hospitalized patients in neonatal intensive care units. Objective To measure the excursion and thickening of the diaphragm and describe measurements among neonates, preterm, and full-term. Methods Diaphragmatic kinesiological ultrasonography was performed on hospitalized newborns, in Neonatal Unit Care Unit, placed in supine position in their own bed, on the sixth day of life. Three repeated measurements of the same respiratory cycle were made, both for excursion and for diaphragmatic thickening. Results 37 newborns participated in the study and 25 were premature. The mean weight at the time of collection was 2,307.0 ± 672.76 grams and the gestational age was 35.7 ± 3.3 weeks. Diaphragmatic excursion increased with increasing gestational age (p = 0.01, df = 0.21) in term infants (p = 0.17, df = 0.35). Conclusion There was a positive correlation between diaphragmatic excursion and gestational age. There was no statistically significant difference in the measurements of excursion and inspiratory diaphragm thickening between preterm and term newborns, although pointing to higher measurements in the latter group.
Resumo Introdução O estudo do músculo diafragma tem des-pertado o interesse dos fisioterapeutas que trabalham com ultrassonografia cinesiológica. Ainda pouco explo-rado, contudo, seus achados podem contribuir para a prática clínica dos pacientes internados em unidades de terapia intensiva neonatal (UTIN). Objetivo Mensurar a excursão e o espessamento diafragmático e descrever as medidas entre recém-nascidos prematuros e a termo. Métodos Realizou-se ultrassonografia cinesiológica diafragmática em recém-nascidos internados em UTIN, posicionados em supino em seu próprio leito, no sexto dia de vida. Foram realizadas três medidas repetidas do mesmo ciclo respiratório, tanto da excursão quanto do espessamento diafragmático. Resultados Participaram do estudo 37 recém-nascidos, dos quais 25 eram pre-maturos. O peso no momento da coleta foi de 2.307,0 ± 672,76 gramas e a idade gestacional foi de 35,7 ± 3,3 semanas. A excursão diafragmática aumentou de acordo com o aumento da idade gestacional (p = 0,01; df = 0,21). A espessura variou entre 0,10 e 0,16 cm durante a inspiração nos prematuros e entre 0,11 e 0,19 cm nos nascidos a termo (p = 0,17; df = 0,35). Conclusão Houve correlação positiva entre a excursão diafragmá-tica e a idade gestacional. Não observou-se diferença estatisticamente significativa das medidas de excursão e de espessamento diafragmático inspiratório entre recém-nascidos prematuros e recém-nascidos a termo, embora apontando para maiores medidas neste último grupo.
RESUMO
Abstract Introduction: cystic fibrosis newborn screening must enable its earlier diagnosis, which may enhance outcomes. This study was a series case of delayed-diagnosis children submitted to cystic fibrosis newborn screening. Description: fourteen children were included; eight (57.1%) were due to false-negative screening, while six (42.9%) were due to processing errors. Two samples collected after 30 days of life were incorrectly classified as negative, and four infants with a positive test could not be located due to screening processing errors. Cystic fibrosis diagnosis was confirmed at a median (IQR) age of 5.3 (4.2-7.4) months. Poor nutritional status was the most prevalent clinical sign at diagnosis, being present in 78.6% of infants. The mean (SD) weight-for-length and length-for-age Z-scores were -3.46 (0.84) and -3.99 (1.16), respectively. Half of the children had Pseudo-Bartter syndrome, and 42.9% had breathing difficulties. Twelve children (85.7%) required hospitalization, with a median (IQR) length of stay of 17.0 (11.5-26.5) days. Discussion: newborn screening had some faults, from incorrect collections to inefficient active search. Early identification of these children in which screening was unsatisfactory is essential, emphasizing the importance and efforts to not miss them. In the case of a failed test, healthcare professionals must be prepared to recognize the main symptoms and signs of the disease.
Resumo Introdução: a triagem neonatal para fibrose cística deve contribuir para diagnóstico precoce e melhor prognóstico da doença. O estudo é uma série de casos com lactentes submetidos à triagem, porém com diagnóstico tardio da doença. Descrição: quatorze crianças foram incluídas; oito (57,1%) com triagem falso-negativo e seis (42,9%) com erros processuais na triagem neonatal. Duas amostras foram coletadas tardiamente, sendo incorretamente classificadas como negativas e quatro lactentes com triagem positiva não foram localizados, por erros na busca ativa. Confirmou-se o diagnóstico da fibrose cística com idade mediana (IIQ) de 5,3 (4,2-7,4) meses. O Comprometimento nutricional precoce foi o sinal clínico mais prevalente ao diagnóstico, presente em 78,6% das crianças. Os Z escores médios (SD) do peso para altura e altura para idade foram -3,46 (0,84) e -3,99 (1,16), respectivamente. Metade das crianças teve síndrome de Pseudo-Bartter e 42,9% dificuldade respiratória. Doze crianças (85,7%) precisaram hospitalização com tempo mediano de permanência de 17 dias. Discussão: a triagem neonatal para fibrose cística apresentou falhas, desde testes falso-negativos, coletas incorretas, até problemas com a busca ativa. Entretanto, o diagnóstico ágil é essencial e os profissionais de saúde devem reconhecer os sintomas e sinais precoces da doença, mesmo quando a triagem neonatal não for satisfatória.

BACKGROUND: Community-based postnatal care is a valuable resource in the provision of maternal and neonatal care, specifically outside the hospital environment. However, its application in maternal and neonatal care is not clearly documented in relation to the rendering of services by primary caregivers. OBJECTIVES: This study clarifies the concept of 'community-based postnatal care' by using the concept analysis method. METHOD: To analyse the concept, relevant literatures were reviewed and analysed using the Walker and Avant method, namely, selecting a concept, determining the purpose of analysis, identifying all uses of the concept, defining attributes, identifying a model case, identifying borderline, related and contrary cases, identifying antecedents and consequences and identifying the empirical referents. Characteristics that repeatedly appeared throughout the literature were noted and categorised. RESULTS: It was established from the concept analysis that 'community-based postnatal care' was complex and experienced ethnically. The analysis included that primary caregiver participation was based on home-levelled-skilled care, community participation and mobilisation, linkages of health services and community stakeholders. The attributes were influenced by antecedents and consequences. CONCLUSION: The empirical referents of community based can be integrated within the midwifery guidelines to measure the concept. When concepts are understood, self-care on early detection, early management and referral during early postnatal care will be enhanced.Contribution: The results of this study will foster independence, confidence and a respectful relationship between primary caregivers and the health care facility staff. The results are expected to guide future research and enhance community-based postnatal care in midwifery practice.
