BACKGROUND: Underweight is a prevalent health issue in children. This study aimed to identify factors associated with underweight in children aged 1-2 years in Hamadan city. Unlike the studies conducted in this field, which are cross-sectional and do not provide information on the effect of age changes on underweight, our longitudinal approach provides insights into weight changes over time. On the other hand, this study focuses on the high-risk age group of 1 to 2 years, which has only been addressed in a few studies.
METHODS: In this longitudinal study, 414 mothers with 1 to 2 year-old children referred to the health centers of Hamadan city, whose information is in the SIB system, a comprehensive electronic system, were examined to identify factors related to underweight. The response variable was weight-for-age criteria classified into three categories: underweight, normal weight, and overweight. A two-level longitudinal ordinal model was used to determine the factors associated with underweight.
RESULTS: Of the children studied, 201 (48.6%) were girls and 213 (51.4%) were boys. Significant risk factors for underweight included low maternal education (AOR = 3.56, 95% CI: 1.10-11.47), maternal unemployment (AOR = 3.38, 95% CI: 1.05-10.91), maternal height (AOR = 0.85, 95% CI: 0.79-0.92), lack of health insurance (AOR = 2.85, 95% CI: 1.04-7.84), gestational age less than 24 years (AOR = 3.17, 95% CI: 16.28-0.97), child age 12-15 months (AOR = 2.27, 95% CI: 1.37-3.74), and child\'s birth weight (AOR = 0.63, 95% CI: 0.70-0.58).
CONCLUSIONS: Based on the results of the present study, it seems that the possibility of being underweight among children is more related to the characteristics of mothers; therefore, taking care of mothers can control some of the weight loss of children.

BACKGROUND: 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.

UNASSIGNED: 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.
UNASSIGNED: 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.
UNASSIGNED: 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.
UNASSIGNED: 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.
UNASSIGNED: 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).

OBJECTIVE: To describe the growth trajectory of children with congenital diaphragmatic hernia (CDH) during the first year, to assess the risk factors for growth failure (GF) at 1 year and to determine nutritional intakes at discharge required for early optimal growth.
METHODS: Single-centre retrospective cohort study based on data from a structured follow-up programme.
METHODS: All neonates with CDH (2013-2019) alive at discharge and followed up to age 1.
METHODS: None.
METHODS: Weight-for-age z-score (WAZ) at birth, 3, 6 and 12 months of age; risk factors for GF at age 1; energy and protein intake of infants achieving early optimal growth.
RESULTS: Sixty-three of 65 neonates who were alive at discharge were included. Seven (11%) had GF at 1 year and 3 (4.8%) had a gastrostomy tube. The mean WAZ decreased in the first 3 months before catching up at 1 year (-0.6±0.78). Children with a severe form or born preterm experienced a deeper loss (from -1.5 to -2 z-scores) with late and limited catch-up. The median energy intake required to achieve positive or null weight growth velocity differed significantly according to CDH severity, ranging from 100 kcal/kg/day (postnatal forms) to 139 kcal/kg/day (severe prenatal forms) (p=0.009).
CONCLUSIONS: Growth patterns of CDH infants suggest that nutritional risk stratification and feeding practices may influence growth outcomes. Our results support individualised and active nutritional management based on CDH severity, with energy requirements as high as 140% of recommended intakes for healthy term infants.

Angelman syndrome (AS) is a rare pediatric neurological condition in which patients most commonly present with inappropriate laughter, microcephaly, speech difficulties, seizures, and movement disorders. AS can be diagnosed clinically and confirmed with genetic testing. In this case report, the patient presented with 9.3% weight loss at two days of age. Although there were multiple attempts at lactational counseling and nutritional guidance, the patient was admitted to the hospital due to failure to thrive. Due to continued global developmental delay and upper and lower extremities hypotonia by the age of nine months, the patient was referred to a neurologist. Brain MRI was negative, and genetic testing revealed 15q11.2q13.1 deletion, which is consistent with AS. Through different therapies and intervention, the patient showed slow improvements in symptoms. This case illustrates the importance of early recognition of nonspecific clinical manifestations of AS. The general management for all AS patients includes physical therapy, speech therapy, mobility support devices, education, and behavioral therapy as they progress through life. Establishing an early diagnosis has potential long-term benefits of improved quality of life and outcomes for patients via early interventions such as physical therapy starting at the age of six months to improve gross motor function. When infants present with nonspecific clinical presentations such as failure to thrive and hypotonia, clinicians should maintain a lower threshold for suspecting genetic conditions, which will facilitate early diagnosis of AS.

The aim of the study was to determine failure to thrive among asylum-seeking children.
The study was a descriptive study.
The sample of the study comprised of 187 children who were registered in an Afghan Association. The power of the study was found to be 97% at 0.5% (moderate) effect size and 95% confidence level.
The data was collected between November 8, 2021 and January 10, 2022 using a sociodemographic form and the children\'s anthropometric measurement.
57.2% of children were male and 44.9% were 6-12 years old. It was determined that female and male infants less than 1 year of age were underweight (z-score = -2) and male infants were stunting (z-score ≤-1).
Childhood growth and development problems are significant issues among asylum-seeking families. Public health nurses need to develop their roles in organizing the healthcare service for vulnerable and underrepresented groups.

UNASSIGNED: Bartter syndrome (BS) is a rare salt-wasting tubulopathy caused by mutations in genes encoding sodium, potassium, or chloride transporters of the thick ascending limb of the loop of Henle and/or the distal convoluted tubule of the kidney. BS is characterized by polyuria, failure to thrive, hypokalemia, metabolic alkalosis, hyperreninemia, and hyperaldosteronism. Potassium and/or sodium supplements, potassium-sparing diuretics, and nonsteroidal anti-inflammatory drugs can be used to treat BS. While its symptoms and initial management are relatively well known, long-term outcomes and treatments are scarce.
UNASSIGNED: We retrospectively reviewed 54 Korean patients who were clinically or genetically diagnosed with BS from seven centers in Korea.
UNASSIGNED: All patients included in this study were clinically or genetically diagnosed with BS at a median age of 5 (range, 0-271) months, and their median follow-up was 8 (range, 0.5-27) years. Genetic diagnosis of BS was confirmed in 39 patients: 4 had SLC12A1 gene mutations, 1 had KCNJ1 gene mutations, 33 had CLCNKB gene mutations, and 1 had BSND mutation. Potassium chloride supplements and potassium-sparing diuretics were administered in 94% and 68% of patients, respectively. The mean dosage of potassium chloride supplements was 5.0 and 2.1 mEq/day/kg for patients younger and older than 18 years, respectively. Nephrocalcinosis was a common finding of BS, and it also improved with age in some patients. At the last follow-up of 8 years after the initial diagnosis, 41% had short stature (height less than 3rd percentile) and impaired kidney function was observed in six patients [chronic kidney disease (CKD) G3, n = 4; CKD G5, n = 2].
UNASSIGNED: BS patients require a large amount of potassium supplementation along with potassium-sparing agents throughout their lives, but tend to improve with age. Despite management, a significant portion of this population exhibited growth impairment, while 11% developed CKD G3-G5.

OBJECTIVE: To assess the level of parental Awareness about growth failure across all of Saudi Arabia and look into the potential influence of covariates (social and demographic) as determinants of the level of knowledge of parents, both mother and father, aged between 18 and 60, and on the national level.
METHODS: A cross-sectional study involving a survey of 4,404 parents, aged between 18 and 60 years, in all administrative regions within Saudi Arabia was undertaken From March 2022 to May 2022.
RESULTS: The majority of participants had average awareness of FTT, and differences in region, as well as in educational and professional levels, had an impact on this awareness, with participants from the western region who hold bachelor\'s degree and employees have a better level of awareness than others.
CONCLUSIONS: To raise awareness, the whole public, especially parents, has to be continuously informed on failure to thrive in children and how to deal with it through educational programs and awareness campaigns.

Dysregulation of RAS or its major effector pathway is the molecular mechanism of RASopathies, a group of multisystemic congenital disorders. Neurologic complications are especially challenging in the management of the rare RASopathy cardiofaciocutaneous (CFC) syndrome. This study evaluated clinical neurologic and neurodevelopmental features and their associations with CFC syndrome gene variants.
A multinational cohort of 138 individuals with CFC syndrome (BRAF = 90, MAP2K1 = 36, MAP2K2 = 10, KRAS = 2) was recruited. Neurologic presentation was captured via clinician review of medical records and caregiver-completed electronic surveys. Validated measures of seizure severity, adaptive function, and gross motor function were obtained.
The overall frequency of intellectual disability and seizures was 82% and 55%, respectively. The frequency and severity of seizures was higher among individuals with BRAF or MAP2K1 variants than in those with MAP2K2 variants. A disproportionate incidence of severe, treatment-resistant seizures was observed in patients with variants in the catalytic protein kinase domain of BRAF and at the common p.Y130 site of MAP2K1. Neurodevelopmental outcomes were associated with genotype as well as seizure severity.
Molecular genetic testing can aid in prediction of epilepsy and neurodevelopmental phenotypes in CFC syndrome. Study results identified potential CFC syndrome-associated variants in the development of relevant animal models for neurologic, neurocognitive, and motor function impairment.
