Cha JH, Kang E, Na JY, Ryu S, Choi YJ, Kim JH. Growth trajectories of children born preterm and full term with low birth weight to preschool ages: A nationwide study. J Clin Endocrinol Metab 2024:dgae208. [PMID: 38563465 DOI: 10.1210/clinem/dgae208] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/31/2024] [Revised: 03/18/2024] [Accepted: 03/26/2024] [Indexed: 04/04/2024]
Abstract
CONTEXT Preterm (PT) and full term with low birth weight (FT-LBW) children are at a high-risk of poor growth outcomes. OBJECTIVE To investigate the growth trajectories of PT and FT-LBW children from birth to preschool ages. METHODS This study included 1,150,508 infants (PT, 41,454; FT-LBW, 38,250) who underwent the first three rounds (4-6, 9-12, and 18-24 months) of the National Health Screening Program for Infants and Children (NHSPIC). Growth measurements were obtained from the NHSPIC database and converted into Z-scores. Growth data at 2, 4, and 6 years old were measured as outcome variables. The impact of being born small on poor growth outcomes was investigated using a generalized estimating equation and Cox proportional-hazards regression analysis. RESULTS The median birth weights of the PT, FT-LBW, and full term (FT) groups were 2.3, 2.4, and 3.2 kg, respectively. The incidence of short stature (height Z-score < -2 standard deviation score [SDS]) and failure to thrive (FTT) (body mass index (BMI) Z-score < -2 SDS) was the highest in the FT-LBW group, followed by the PT and FT groups. At 4 years old, the incidence rates were 6.0% vs. 5.2% vs. 1.9% for short stature and 4.6% vs. 3.9% vs. 1.7% for FTT. The β estimate of height outcome was lower in both the PT (-0.326 SDS) and FT-LBW (-0.456 SDS) groups. CONCLUSIONS The FT-LBW group was consistently shorter and lighter throughout the preschool period than the PT group, highlighting the significance of growth monitoring in high-risk populations.

Abstract
PURPOSE YKT6 plays important roles in multiple intracellular vesicle trafficking events but has not been associated with Mendelian diseases. METHODS We report 3 unrelated individuals with rare homozygous missense variants in YKT6 who exhibited neurological disease with or without a progressive infantile liver disease. We modeled the variants in Drosophila. We generated wild-type and variant genomic rescue constructs of the fly ortholog dYkt6 and compared their ability in rescuing the loss-of-function phenotypes in mutant flies. We also generated a dYkt6KozakGAL4 allele to assess the expression pattern of dYkt6. RESULTS Two individuals are homozygous for YKT6 [NM_006555.3:c.554A>G p.(Tyr185Cys)] and exhibited normal prenatal course followed by failure to thrive, developmental delay, and progressive liver disease. Haplotype analysis identified a shared homozygous region flanking the variant, suggesting a common ancestry. The third individual is homozygous for YKT6 [NM_006555.3:c.191A>G p.(Tyr64Cys)] and exhibited neurodevelopmental disorders and optic atrophy. Fly dYkt6 is essential and is expressed in the fat body (analogous to liver) and central nervous system. Wild-type genomic rescue constructs can rescue the lethality and autophagic flux defects, whereas the variants are less efficient in rescuing the phenotypes. CONCLUSION The YKT6 variants are partial loss-of-function alleles, and the p.(Tyr185Cys) is more severe than p.(Tyr64Cys).

THE LANCET REGIONAL HEALTH. WESTERN PACIFIC 2024; 44:101002. [PMID: 38322730 PMCID: PMC10844746 DOI: 10.1016/j.lanwpc.2023.101002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/20/2023] [Revised: 12/09/2023] [Accepted: 12/24/2023] [Indexed: 02/08/2024]
Abstract
Background The prevalence and risk factors for failure to thrive (FTT) in pediatric patients with congenital heart disease (CHD) remain ambiguous. We aimed to investigate the prevalence, growth profiles, risk factors, and vulnerable subtypes of CHD associated with FTT in pediatric patients with CHD. Methods This was a cross-sectional study based on Chinese Database for Congenital Heart Surgery. FTT was defined as either stunting or underweight (height or weight standard deviation score <-2), and they were standardized by references of normal Chinese population. Risk factors was determined with logistic regression model, and growth profiles were delineated in each subgroup. Findings A total of 13,256 CHD patients were included in this study, with 3994 patients of mild CHD, 7195 patients of moderate CHD and 2067 patients of complex CHD. The prevalence of stunting, underweight and FTT was 24%, 29.3% and 36.9%, respectively. Preoperative anaemia, left ventricle systolic dysfunction, younger age, more complex CHD types, lower birth weight and genetic syndrome were found to be the risk factors for FTT in CHD patients. Interrupted aortic arch was revealed to be the most severe group associated with FTT. Interpretation FTT is ubiquitous in patients with CHD and exacerbated in high-risk subgroups. Our findings hinted the necessity of early identification and intervention for FTT in patients with CHD during daily practice of pediatrics, as it has the potential to improve outcomes and enhance their quality of life. Furthermore, we advocate for the initiation of prospective research with longitudinal data to comprehensively investigate the association between FTT and CHD across the lifespan. Funding This study was supported by National High Level Hospital Research Funding (2022-GSP-GG-19), Capital Health Research and Development of Special Fund (2022-1-4032) and National Key R&D Program of China (2022YFC3600202 and 2022YFC3600203).

Abstract
An infant was admitted with suspected postinfectious malabsorption with watery diarrhoea, fever and failure to thrive. She had dehydration, acute kidney injury and metabolic acidosis, which were corrected with intravenous fluids and managed with empiric antibiotics and prophylactic antifungals. She also developed Escherichia coli sepsis, meningitis and Candida skin infections during hospitalisation, which were treated according to the culture reports. Intrauterine growth restriction, woolly hair and a broad nasal bridge with chronic refractory diarrhoea prompted genetic testing to rule out syndromic diarrhoea. Whole-exome sequencing revealed a pathogenic compound heterozygous mutation causing trichohepatoenteric syndrome. She succumbed to severe infections at 80 days of life. The condition is rare, and no established guidelines or specific treatments exist; the focus is to promote optimal growth through parenteral nutrition, elemental formula and infection control. Early suspicion and molecular genetic testing can help reduce the time to diagnosis, treatment and genetic counselling.

Abstract
We present a case of a male neonate who experienced a 13.5% weight loss at 96 hours of life, despite receiving adequate calorie intake and exhibiting no feeding difficulties. The pregnancy was uneventful, and maternal serological investigation was normal. A routine ultrasound at 34 weeks of gestational age revealed late oligohydramnios. The neonate was delivered at 35 weeks of gestational age by forceps, weighing 2600 g. Physical examination disclosed bilateral cryptorchidism. Laboratory studies unveiled acute kidney injury (AKI) with hyperkalaemia. Renal ultrasound revealed bilateral hydronephrosis and renal dysplasia with pyelocalyceal dilatation. Despite early recognition and treatment, the newborn developed chronic kidney disease (CKD). AKI is an important and under-recognised cause of significant neonatal weight loss.This case underscores the significance of considering AKI as a potential and under-recognised cause of neonatal weight loss. It emphasises the importance of maintaining a high clinical suspicion for early AKI diagnosis to mitigate the risk of progression to CKD.

Abstract
BACKGROUND Malnutrition (undernutrition) in children with congenital disease (CHD) is a notable concern, with preoperative and persistent growth failure post-cardiac surgery contributing to poorer outcomes. Poor growth in children with CHD in low-income environments is exacerbated by feeding difficulties, poverty, delayed diagnosis, and late corrective surgery. This study describes and compares the growth of young children with CHD undergoing cardiac surgery in central South Africa from before to 6-months after cardiac surgery. METHODS Children 30 months and younger, with their mothers, were included in this prospective observational descriptive study. Weight- height-, and head circumference-for-age z-scores were used to identify children who were underweight, stunted and microcephalic. Z-scores for growth indices were compared from baseline to 3-months and 6-months post-cardiac surgery. Changes in growth over time were calculated using a 95% confidence interval on the difference between means. Linear regression was used to determine the association between growth and development, health-related quality of life and parenting stress respectively. RESULTS Forty mother-child pairs were included at baseline. Most children (n = 30) had moderate disease severity, with eight children having cyanotic defects. A quarter of the children had Down syndrome (DS). Twenty-eight children underwent corrective cardiac surgery at a median age of 7.4 months. Most children (n = 27) were underweight before cardiac surgery [mean z-score - 2.5 (±1.5)], and many (n = 18) were stunted [mean z-score - 2.2 (±2.5)]. A quarter (n = 10) of the children had feeding difficulties. By 6-months post-cardiac surgery there were significant improvements in weight (p = 0.04) and head circumference (p = 0.02), but complete catch-up growth had not yet occurred. Malnutrition (undernutrition) was strongly associated (p = 0.04) with poorer motor development [Mean Bayley-III motor score 79.5 (±17.5)] before cardiac surgery. Growth in children with cyanotic and acyanotic defects, and those with and without DS were comparable. CONCLUSION Malnutrition (undernutrition) is common in children with CHD in central South Africa, a low-income environment, both before and after cardiac surgery, and is associated with poor motor development before cardiac surgery. A diagnosis of CHD warrants regular growth monitoring and assessment of feeding ability. Early referral for nutritional support and speech therapy will improve growth outcomes.

Abstract
Failure to thrive (FTT) is a DSM-5/ICD-10 diagnosis which describes infants and children who fail to grow within expected norms. The causes for poor growth are multifactorial and often include psychosocial factors. Social workers are important players in an interdisciplinary team approach to this diagnosis. This research and manuscript focus on the use of an integrated infant mental health pediatric model of practice, and outcomes for one case study. The article will review the social worker's role in the treatment of FTT, effective social work services provided in an integrated behavioral health approach, and a review of a cost-benefit analysis of treatment of FTT in a Primary Care Facility verses a hospital setting.

Abstract
TRPM6 is predominantly expressed in the kidney and colon and encodes a protein containing an ion channel domain and a protein kinase domain. It is crucial for magnesium homeostasis and plays important roles in epithelial magnesium transport and the active magnesium absorption. In this study, we present a 70-day-old Iranian female patient from consanguineous parents with hypomagnesemia and secondary hypocalcemia. She presented with seizures 19 days after birth and refractory watery non-bloody diarrhea. She consequently had failure to thrive. Other features included hypotonia, wide anterior fontanel, ventriculomegaly, and pseudotumor cerebri following administration of nalidixic acid. She had severe hypomagnesemia and hypocalcemia which were treated with magnesium and calcium supplementation. Despite initial unstable response to supplemental magnesium, she eventually improved and the diarrhea discontinued. The patient was discharged by magnesium and calcium therapy. At the last follow-up at age 2.5 years, the patient remained well without any recurrence or complication. Genetic testing by whole-exome sequencing revealed a novel homozygous frameshift insertion-deletion (indel) variant in exon 26 of the TRPM6 gene, c.3693-3699del GCAAGAG ins CTGCTGTTGACATCTGCT, p.L1231Ffs*36. Segregation analysis revealed the TRPM6 heterozygous variant in both parents. Patients with biallelic TRPM6 pathogenic variants typically exhibit hypomagnesemia with secondary hypocalcemia and present with neurologic manifestations including seizures. In some patients, this is also complicated by chronic diarrhea and failure to thrive. Long-term complications are rare and most of the patients show a good prognosis with supplemental magnesium therapy.

Abstract
BACKGROUND Shwachman-Diamond syndrome (SDS) is an autosomal recessive disease which results in inherited bone marrow failure (IBMF) and is characterized by exocrine pancreatic dysfunction and diverse clinical phenotypes. In the present study, we reviewed the internationally published reports on SDS patients, in order to summarize the clinical features, epidemiology, and treatment of SDS. METHODS We searched the WangFang and China National Knowledge Infrastructure databases with the keywords "Shwachman-Diamond syndrome," "SDS," "SBDS gene" and "inherited bone marrow failure" for relevant articles published from January 2002 to October 2022. In addition, studies published from January 2002 to October 2022 were searched from the Web of Science, PubMed, and MEDLINE databases, using "Shwachman-diamond syndrome" as the keyword. Finally, one child with SDS treated in Tongji Hospital was also included. RESULTS The clinical features of 156 patients with SDS were summarized. The three major clinical features of SDS were found to be peripheral blood cytopenia (96.8%), exocrine pancreatic dysfunction (83.3%), and failure to thrive (83.3%). The detection rate of SDS mutations was 94.6% (125/132). Mutations in SBDS, DNAJC21, SRP54, ELF6, and ELF1 have been reported. The male-to-female ratio was approximately 1.3/1. The median age of onset was 0.16 years, but the diagnostic age lagged by a median age of 1.3 years. CONCLUSIONS Pancreatic exocrine insufficiency and growth failure were common initial symptoms. SDS onset occurred early in childhood, and individual differences were obvious. Comprehensive collection and analysis of case-related data can help clinicians understand the clinical characteristics of SDS, which may improve early diagnosis and promote effective clinical intervention.

Abstract
This report presents a case of childhood Gaucher disease type 1, a rare inherited metabolic disorder. Although the clinical symptoms were classical, the histological findings in this case were atypical and initially led to diagnostic uncertainty. The pathognomonic histological finding on bone marrow is Gaucher cells, which are lipid-engorged phagocytes secondary to the accumulation of glucosylceramide. These cells typically demonstrate diffuse and avid iron staining using a Prussian blue iron stain. In this case, although the histiocytes seen on bone marrow were abnormal, the absence of iron staining on bone marrow led to a large range of other diagnoses being considered. In retrospect, this anomaly was likely in the setting of prolonged iron deficiency and anaemia as a result of the insidious nature of this presentation. The prognosis of type 1 Gaucher disease is favourable, with current treatments significantly improving duration and quality of life. We explore the utility of a collaborative multidisciplinary approach in addressing diagnostic uncertainty and the importance in making a diagnosis for Gaucher disease type 1 in order to provide appropriate and targeted treatment.

Abstract
A boy presented with cough, breathlessness for 1 month, fever for 1 week with similar previous episodes without hospitalisation. He had generalised muscle wasting, acute chronic malnutrition and required immediate ventilation. Provisional diagnosis of recurrent pneumonia with failure to thrive was made. As serial chest X-rays showed recurrent lung collapse, congenital lung anomalies were ruled out. 2D-echocardiography showed pulmonary arterial hypertension. Workup for congenital immunodeficiency and cystic fibrosis was negative. There was no improvement in muscle mass despite total parenteral nutrition. He was noticed to have myopathic facies. History was reviewed when the mother reported reduced fetal movements in this pregnancy. The patient had low voice amplitude. Creatine kinase levels were normal. Muscle biopsy followed by whole exome sequencing identified frameshift duplication NM_020451.3(SELENON):c.249_250dupGG (p.Asp84Glyfs*17), thus, confirming diagnosis of SEPN1-related congenital myopathy (CM) with fibre-type disproportion. Respiratory system involvement was distracter, emphasising consideration of CM while evaluating persistent lung collapse with muscle wasting.

Abstract
Neonates show considerable variation in growth that can be recognized through serial measurements of basic variables such as weight, length, and head circumference. If possible, measurement of subcutaneous and total body fat mass can also be useful. These biometric measurements at birth may be influenced by demographics, maternal and paternal anthropometrics, maternal metabolism, preconceptional nutritional status, and placental health. Subsequent growth may depend on optimal feeding, total caloric intake, total metabolic activity, genetic makeup, postnatal morbidities, medications, and environmental conditions. For premature infants, these factors become even more important; poor in utero growth can be an important reason for spontaneous or induced preterm delivery. Later, many infants who have had intrauterine growth restriction (IUGR) and are born small for gestational age (SGA) continue to show suboptimal growth below the 10th percentile, a condition that has been defined as extrauterine growth restriction (EUGR) or postnatal growth restriction (PNGR). More importantly, a subset of these growth-restricted infants may also be at high risk of abnormal neurodevelopmental outcomes. There is a need for well-defined criteria to recognize EUGR/PNGR, so that correctional steps can be instituted in a timely fashion.

Abstract
PURPOSE Russel described a rare clinical entity known as diencephalic syndrome (DS) in 1951, which was traditionally caused by a neoplasm in the hypothalamic-optic chiasmatic region. DS is characterized by severe emaciation despite adequate or slightly reduced caloric intake, locomotor hyperactivity, euphoria and other minor features. Current evidence suggests that a rare population of children with a similar phenotype may have their tumor located in the posterior fossa instead, defining the DS-like presentation, a rare entity with few cases reported in the literature. METHODS A thorough search of three databases (PubMed, Ovid Medline, and Ovid Embase) was conducted to identify relevant papers reporting children with DS associated with brainstem tumors. To our knowledge, only seven cases have been documented in the literature. Moreover, we present four of our own cases, focusing on the unusual clinical presentation, the diagnosis process, and the lag time between the initial symptoms and the definitive diagnosis. RESULTS In this review, the mean lag time between the onset of symptoms and diagnosis was 20.9 months (median: 16 months; range: 1.5-72 months), whereas in our series of cases, the time was 32.5 months (median: 33 months; range: 7-57 months). CONCLUSION Despite recent significant advances in neuro-oncology diagnostic tools, this mean lag time did not improve when compared with the previous literature review from 1976. Throughout these data, we aim to raise awareness in the hopes of detecting intracranial neoplasms earlier in cases of children with profound emaciation of unknown cause.

Abstract
Eosinophilic gastrointestinal disorders (EGIDs) are chronic/remittent inflammatory diseases associated with a substantial diagnostic delay, often attributable to misdiagnosis and variable clinical presentation in adults. In the pediatric population, few studies have been conducted worldwide reporting EGID diagnostic delay and its consequences on patients. This study aims to analyze and identify potential clinical factors and complications associated with a longer diagnostic time. We performed a retrospective analysis of pediatric patients with EGIDs followed at the Center for Pediatric EGIDs in Pavia, Italy. A total of 60 patients with EGIDs were enrolled. Thirty-nine (65%) patients had EoE, and 21 (35%) non-esophageal EGIDs. EGID diagnosis was achieved about 2 years after the symptom onset, and the median diagnostic time was 12 months (IQR 12-24 months). Diagnostic time was 12 months (IQR 12-69) in non-esophageal EGIDs and 12 months (IQR 4-24 months) in EoE patients. EoE patients presenting with FTT and feeding issues experienced a longer diagnostic time (p = 0.02 and p = 0.05, respectively) than children without growth and feeding impairments.In this study, symptoms appeared about 2 years before the definitive EGID diagnosis was reached, and this diagnostic time was shorter than the delay observed in other published studies. Especially in EoE children, the diagnostic time is significantly associated with impaired child growth, highlighting the importance of an early diagnosis to prevent esophageal stenosis and failure to thrive.

Abstract
The RFX7 gene is one of eight genes within the regulatory factor X family. RFX7 is highly expressed in the brain and plays an important role in cell maturation and differentiation. It has only recently been implicated in disease in humans. Reports from 15 individuals have described RFX-associated phenotype as a neurobehavioural disease, manifesting primarily with global developmental delay and intellectual disability. Autism spectrum disorder and attention deficit hyperactivity disorder have also been described in some children. Here we report a case of a 19-month-old with a de novo missense variant in RFX7 resulting in severe global developmental delay including significant speech delay, microcephaly, dyskinetic movements, and failure to thrive. This is the first association between variants in RFX7 and failure to thrive, expanding the phenotype of this newly described gene. In this report we will also show RFX7 associated progressive central nervous system involvement through serial brain imaging.

Abstract
BACKGROUND Gastrostomy tube (GT) placement is a common procedure in infants (≤1-year-old). There is variation in patient selection and a paucity of studies examining which patients require long term enteral access. The objective of this study was to assess demographic and clinical factors associated with persistent GT use (PGU) at 1-year after placement. METHODS We performed a single-institution retrospective review of patients ≤1-year-old who underwent GT placement from January 31, 2014, and January 31, 2020, using institutional NSQIP-P data supplemented with chart review. Multivariable logistic regression analysis was performed to identify factors associated with PGU. Clinical predictors were selected a priori, and a p-value less than 0.05 was used to detect a significant association. RESULTS 140 patients were included, and 118 had a 1-year follow-up. At 1-year following GT placement, 38 patients had weaned from their GT (32.2%). Failure to thrive (FTT), and inpatient admission prior to surgery are associated with increased odds of PGU at 1-year after surgery, OR: 5.19 and 6.02, respectively. There is an inverse association between the percentage of feeds taken by mouth at the time of surgery and the odds of PGU at 1-year (OR: 0.03). CONCLUSION Patients who have FTT (documented prior to surgery) or an inpatient admission prior to GT had a higher odds of PGU at 1-year post-op. Additionally, the amount taken by mouth at the time of GT placement was inversely related to PGU. These factors are important in determining the need for a surgical gastrostomy tube. LEVEL OF EVIDENCE II.

Abstract
INTRODUCTION Diencephalic syndrome (DS) is a rare syndrome with failure to thrive (FTT) as the primary manifestation, which is often associated with astrocytoma or glioma and rarely caused by germinoma. To our knowledge, there are no reports of female patients presenting with DS secondary to germinoma. CASE REPORT we report a case (an 11-year-old girl) of diencephalic syndrome presenting with FTT. She was diagnosed with severe malnutrition in the local hospital two years before admission and still did not show normal development after long-term nutritional support. Finally, after ruling out increased metabolism, inadequate caloric intake, and nutrient absorption, intracranial MRI showed a space-occupying lesion in the suprasellar cisterna-hypothalamus area. After excluding other causes of FTT, a biopsy was performed for pathological examination and demonstrated a germinoma. An excellent therapeutic effect was achieved during the three-month follow-up after radiotherapy. CONCLUSION This case reminds us that intracranial tumors should be considered an indispensable etiology for patients with suspicious FTT, and early diagnosis and intervention may achieve a good prognosis.

Abstract
The aim of our study was to better define the clinical pattern of diencephalic syndrome, a rare but potentially lethal cause of failure to thrive in infancy. Poor weight gain or weight loss, the characteristic presenting feature, often firstly attributed to gastrointestinal or endocrinological or genetic diseases, is secondary to a malfunctioning hypothalamus, caused by a diencephalic tumor. Due to its unexpected clinical onset, diagnostic delay and misdiagnosis are common. We described a case series of 3 children with diencephalic syndrome admitted at our Hospital, over a 5-year period. Furthermore, a narrative review on all pediatric cases published in the last seventy years was performed. Clinical pattern, timing to diagnosis, neuroimaging, management, and outcome were analyzed. Our three cases are singularly described in all clinical and diagnostic findings. Overall, 100 children were selected; all these cases as well as our children presented with failure to thrive: 96% had body mass index or weight-length/height ratio lower than 5th percentile. Vomiting and hyperactivity are reported in 35 and 26% of cases, respectively. The neurological features, mainly nystagmus reported in 43%, may occur late in the disease course. In conclusion, the diagnostic delay is the hallmark of diencephalic syndrome, confirming the lack of knowledge by clinicians. The poor weight gain/loss despite adequate length growth and food intake, especially in children with hyperactivity and good psychomotor development, should alert pediatricians towards this condition, before neurological signs/symptoms occurrence.

Growth and morbidity in infants with Congenital Diaphragmatic Hernia according to initial lung volume: A pilot study. J Pediatr Surg 2022; 57:643-648.

Abstract
Background In congenital diaphragmatic hernia (CDH) survivors, failure to thrive is a well-known complication, ascribed to several factors. The impact of lung volume on growth of CDH survivors is poorly explored. Our aim was to evaluate if, in CDH survivors, lung volume (LV) after extubation correlates with growth at 12 and 24 months of life. Methods LV (measured as functional residual capacity-FRC) was evaluated by multibreath washout traces with an ultrasonic flowmeter and helium gas dilution technique, shortly after extubation. All CDH survivors are enrolled in a dedicated follow-up program. For the purpose of this study, we analyzed the correlation between FRC obtained shortly after extubation and anthropometric measurements at 12 and 24 months of age. We also compared growth between infants with normal lungs and those with hypoplasic lungs according to FRC values. A p < 0.05 was considered as statistically significant. Results We included in the study 22 CDH survivors who had FRC analyzed after extubation and auxological follow-up at 12 and 24 months of age. We found a significant correlation between FRC and weight Z-score at 12 months, weight Z-score at 24 months and height Z-score at 24 months. We also demonstrated that CDH infants with hypoplasic lungs had a significantly lower weight at 12 months and at 24 months and a significantly lower height at 24 months, when compared to infants with normal lungs. Conclusion We analyzed the predictive value of bedside measured lung volumes in a homogeneous cohort of CDH infants and demonstrated a significant correlation between FRC and growth at 12 and 24 months of age. An earlier identification of patients that will require an aggressive nutritional support (such as those with pulmonary hypoplasia) may help reducing the burden of failure to thrive.
