There is a well-established association between cystic fibrosis (CF) and malnutrition. Several comorbid conditions have also been associated with undernutrition in people with cystic fibrosis (PwCF). Highly effective modulator therapy has allowed for a paradigm shift altering disease progression and management. Modulator use has even been associated with acceleration of weight trajectory causing overnutrition, which can lead to cardiovascular and metabolic comorbid conditions. This review explores how nutritional status is evolving in the era of cystic fibrosis transmembrane conductance regulator (CFTR) modulators in people with CF, specifically in children. By synthesizing current research, we aim to support pediatric healthcare providers and nutritionists in delivering tailored, proactive nutritional care in this new therapeutic landscape.

Childhood obesity is a major global health problem, and its management involves a multidisciplinary approach that includes lifestyle changes, dietary interventions, and the use of dietary supplements. In this review, we summarize current findings on the role of amino acids in pediatric obesity, with a particular focus on their involvement in metabolic pathways and weight regulation. The involvement of branched-chain and aromatic amino acids in the pathophysiology and potential management of pediatric obesity is highlighted in recent studies. Both experimental and clinical studies have shown that obese children often exhibit altered plasma amino acid profiles, including increased levels of leucine, isoleucine, valine, phenylalanine, and tyrosine, as well as decreased levels of glycine and serine. These imbalances are correlated with insulin resistance, inflammation, and early metabolic dysfunction. One of the mechanisms through which branched-chain amino acids can promote insulin resistance is the activation of the mammalian target of rapamycin (mTOR) signaling pathway. Metabolomic profiling has demonstrated the potential of specific amino acid patterns to predict obesity-related complications before they become clinically evident. Early identification of these biomarkers could be of great help for individualized interventions. Although clinical studies indicate that changes in dietary amino acids could lead to modest weight loss, improved metabolic profiles, and increased satiety, further studies are needed to establish standardized recommendations.

Background: Cyclic vomiting syndrome (CVS) is a functional gastrointestinal disorder characterized by recurrent episodes of intense nausea and vomiting. Despite increasing awareness, a standardized treatment approach remains lacking in pediatric populations. Lifestyle factors and anxiety are common triggers, yet their systematic management has not been fully incorporated into therapeutic strategies. Objective: To evaluate the effectiveness of lifestyle modifications and selective serotonin reuptake inhibitors (SSRIs) in the management of pediatric CVS and to compare their outcomes with standard cyproheptadine prophylaxis. Methods: This retrospective study included 119 patients aged 1.2–17.5 years who were diagnosed with CVS according to Rome IV criteria between September 2021 and January 2025. Clinical, psychiatric, and lifestyle data were retrieved from the university’s digital medical records. Patients were grouped according to treatment modality: cyproheptadine, SSRI, or acute attack management alone. Treatment success at 12 weeks was defined as complete cessation of vomiting episodes or absence of hospitalization, prolonged attacks, and school/work absenteeism. Results: Anxiety symptoms were present in 78.2% of patients. SSRIs were prescribed to 34 patients with moderate to severe anxiety, all of whom achieved treatment success. Lifestyle adherence was observed in 73.9% and was found to be a predictor of treatment success. Cyproheptadine was administered to 66 patients but did not provide additional benefit over effective lifestyle modification. Six patients discontinued cyproheptadine due to drowsiness or weight gain. Conclusions: Lifestyle interventions significantly improve outcomes in pediatric CVS. SSRIs represent a safe and effective prophylactic option for patients with comorbid anxiety or poor adherence to behavioral recommendations. These findings support the integration of psychosocial and lifestyle-based strategies into standard CVS treatment protocols. Full article

Background/Objectives: Subtalar arthroereisis (STA) is a widely used surgical procedure for symptomatic pediatric flexible flatfoot. However, implant migration remains a concern due to its potential impact on long-term correction and complications. This study evaluated the migration pattern of STA implants and assessed long-term clinical and radiographic outcomes. Methods: This retrospective cohort study included 47 feet from children aged 8–13 years who underwent STA with adjunctive soft tissue procedures between 2014 and 2018, following ≥6 months of failed conservative treatment, with a minimum follow-up of 5 years. Exclusion criteria included neuromuscular or rigid flatfoot. Weight-bearing radiographs assessed anteroposterior (AP) and lateral Meary’s angles, reflecting forefoot-to-hindfoot alignment, and calcaneal pitch, indicative of longitudinal arch height. Implant migration was recorded and clinical outcomes were measured by the American Orthopedic Foot and Ankle Society (AOFAS) score. Measurements were recorded preoperatively, immediately postoperatively, and at 1 month, 3 months, 6 months, 1 year, and 5 years. Results: Radiographic correction was significant and sustained at 5 years. The AP Meary’s angle improved from 13.09° to 5.26° at 1 month and 6.69° at 5 years (p < 0.001); lateral Meary’s angle from 9.77° to 4.06° and 4.88° (p < 0.001); and calcaneal pitch from 14.52° to 16.87° and 16.89° (p < 0.001), respectively. AOFAS scores increased from 67.52 to 90.86 at 1 month and 96.33 at 5 years (p < 0.001). Implant migration peaked within the first postoperative month (mean: 3.2 mm on ankle AP view; 3.0 mm on foot AP view) and stabilized thereafter. Four cases of complications included implant dislodgement, subsidence, and persistent sinus tarsi tenderness, which were successfully resolved after appropriate management. No recurrence of deformity was observed. Conclusions: STA implant migration is most pronounced during the first month, likely due to physiological settling as the foot adapts to altered biomechanics. With appropriate implant selection, technique, and follow-up, migration does not compromise long-term correction or outcomes. In general, symptomatic cases can often be managed conservatively prior to implant removal. Full article

Background High-sensitivity C-reactive protein (hs-CRP) is a protein that indicates inflammation and the risk of cardiovascular diseases. The intake of dietary amino acids can influence immune and inflammatory reactions. However, studies on the relationship between dietary amino acids and hs-CRP, especially in children, remain scarce. Methods This cross-sectional study analyzed data from the Nutrition and China Children and Lactating Women Nutrition and Health Survey (2016–2019), focusing on 3514 children (724 with elevated hs-CRP ≥ 3 mg/L and 2790 with normal levels). Dietary information was gathered via a food frequency questionnaire, and hs-CRP levels were obtained from blood samples. Boruta algorithm and propensity scores were used to select and match dietary factors and sample sizes. Machine learning (ML) algorithms and logistic regression models assessed the link between amino acid intake and elevated hs-CRP risk, adjusting for age, sex, BMI, and lifestyle factors. Results The odds ratios (ORs) for elevated hs-CRP were significant for several amino acids, including Ile, Leu, Lys, Ser, Cys, Tyr, His, Pro, SAA, and AAA, with values ranging from 1.10 to 2.07. The LightGBM algorithm was the most effective in predicting elevated hs-CRP risk, achieving an AUC of 0.927. Tyrosine, methionine, cysteine, and proline were identified as important features by SHAP analysis and logistic regression. The intake of Ser, Cys, Tyr, and Pro showed a linear increase in the risk of elevated hs-CRP, especially in individuals with low protein intake and normal weight (p < 0.1). Conclusions Intake of amino acids like Ser, Cys, Tyr, and Pro significantly impacts hs-CRP levels in children, indicating that regulating these could help prevent inflammation-related diseases. This study supports future dietary and health management strategies. This is first large-scale ML study linking amino acids to pediatric inflammation in China. The main limitations are the cross-section design and the use of self-reported dietary data. Full article

Cryptococcosis, an opportunistic fungal infection predominantly caused by Cryptococcus neoformans, is the third most common invasive fungal disease in solid organ transplant recipients. While well-characterized in adult kidney transplant (KT) patients, pediatric data remain sparse. This article compares clinical presentation, immune response, renal involvement, and management strategies of cryptococcosis between adult and pediatric KT recipients. In adults, the disease typically presents as cryptococcal meningitis or pulmonary infection, often complicated by delayed diagnosis and high mortality. In contrast, children frequently exhibit non-specific respiratory symptoms or disseminated disease, reflecting immune immaturity and increased susceptibility to hematogenous spread. Key immunopathological differences include impaired Th1 type responses, macrophage dysfunction, and variable complement activity across age groups. Management involves similar antifungal regimens such as liposomal amphotericin B, flucytosine, and fluconazole, but requires weight-based dosing and careful toxicity monitoring in pediatric patients. Early diagnosis through serum cryptococcal antigen screening, appropriate adjustment of immunosuppressive therapy, and coordinated multidisciplinary care are essential. The findings underscore the need for pediatric specific research and clinical vigilance, emphasizing tailored antifungal dosing and individualized immune management to improve outcomes in this vulnerable population.

Despite advances in technology, the overall management of type 1 diabetes mellitus (T1DM) remains suboptimal. The idea of restricting carbohydrate intake to decrease glycemic spikes and insulin requirements has been revisited in recent years. After impressive results in the fields of type 2 diabetes (T2DM) and epilepsy, low-carbohydrate (LCD) and ketogenic (KD) diets have gained renewed interest as a possible treatment option for T1DM. In this narrative review, we discuss the available data regarding LCDs and KDs in both the adult and pediatric populations. Research data is still scarce, as most studies are short-term and show considerable heterogeneity in dietary composition and patient outcomes. In general, carbohydrate restriction enhances glycemic control by reducing postprandial glucose excursions, improving time-in-range, and lowering HbA1c, with conflicting effects on other parameters such as lipid profile and body weight. Adverse effects such as hypoglycemia and diabetic ketoacidosis are rarely reported, although some concerns have been raised regarding growth in children. The correct implementation of these diets requires a multidisciplinary approach by highly specialized healthcare professionals, who will address the medical, social, and psychological concerns that a restrictive diet entails. Large-scale and long-term studies are needed to provide more robust data before carbohydrate restriction can be widely applied to patients with T1DM. Full article

Type II diabetes mellitus (T2D) is a metabolic disorder. Childhood overweight or obesity raises the risk for developing T2D later in life. Early identification of at-risk individuals is fundamental for disease prevention and patient management. The scope of this pilot study was to explore whether leukocyte protein O-GlcNAc modification is elevated in an overweight pediatric cohort. Eight overweight and eight normal-weight children aged 3–13 years were recruited at the Papardo General Hospital (Messina, Italy). Physical exams, complete blood tests, and determination of leukocyte protein O-GlcNAcylation were carried out. Protein O-GlcNAcylation was higher in leucocytes from overweight children compared to normal-weight children, and was significantly correlated with BMI, metabolic markers (LDL-cholesterol/triglycerides), and the inflammatory marker CRP. This study suggests that leukocyte protein O-GlcNAcylation may represent a novel biomarker for the early detection of metabolic abnormalities that may lead to the development of pre-diabetes or T2D later in life.

Background/Objectives: Flatfoot is a common pediatric foot deformity characterized by a reduced or absent medial longitudinal arch (MLA). The condition can lead to altered gait, pain, and potential long-term morbidity if untreated. Identifying potential risk factors—such as body mass index (BMI), ligamentous or joint instability, shoe choices, and physical activity—is crucial for prevention and management. The objectives are to systematically review and synthesize current evidence on how flatfoot severity correlates with BMI and other risk factors in children and adolescents, and to highlight methodological considerations essential for future research. Methods: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we searched five electronic databases from inception to February 2024. Flatfoot severity was measured by various clinical or radiographic indices. Two reviewers independently screened and assessed the risk of bias. Results: Thirty-seven studies met the inclusion criteria. Children with high BMI had increased odds of flatfoot (pooled Odds Ratio = 2.3, 95% Confidence Interval: 1.6–3.1), with one outlier reporting an OR of 9.08. Heterogeneity (I² up to 70%) stemmed from varied diagnostic methods. Other factors, including joint instability, shoe choices, and physical activity, showed mixed associations. Conclusions: Elevated BMI strongly correlates with pediatric flatfoot severity, highlighting the importance of proactive weight management and foot assessments. Future standardized, longitudinal studies are needed to clarify causality and refine interventions. Full article

Objectives: Early observations often fail to detect anomalies that may impact the health and quality of life of newborns. This study aimed to determine the prevalence of oral anomalies in newborns and explore their possible associations with sociodemographic factors. Methods: A cross-sectional study was conducted in Quito, Ecuador, analyzing a sample of 241 newborns. The presence of oral anomalies was recorded, and their association with sex, birth weight, maternal age, and gestational factors was evaluated. Results: The prevalence of oral anomalies was 72.3%, with Epstein’s pearls being the most common (50%). Other findings included Bohn’s nodules and dental lamina cysts, while no cases of natal teeth or congenital epulis were observed. Ankyloglossia was identified in 1.36% of newborns. No significant correlations were found between the presence of oral anomalies and sex, birth weight, maternal age, or gestational factors. Conclusions: The high prevalence (72.3%) of oral anomalies in the studied newborns underscores the importance of early detection and management. Epstein’s pearls were the most frequent anomaly, followed by Bohn’s nodules, dental lamina cysts, and ankyloglossia, while no cases of natal teeth or congenital epulis were identified. No statistically significant associations were found with sex, birth weight, maternal age, or pregnancy complications. These findings emphasize the need for early pediatric dental assessment and an interdisciplinary approach to ensure proper neonatal oral health. Further research is recommended to explore potential causes and interventions to optimize oral health from birth. Full article

Although there are over 5 million cases of snakebites each year, up-to-date data on epidemiology and management in European children are lacking in literature. Snakebite envenoming is a rare but potentially life-threatening event, and children are more susceptible due to their lower weight-to-venom ratio. Symptoms of viper envenomation in children are mainly local, but the lymphatic and blood diffusion of the venom may cause systemic symptoms, mainly hemotoxic and cytotoxic symptoms. Immunotherapy with anti-viper serums is the cornerstone of treatment for viper bites, while the use of antibiotics, steroids and analgesics is still unclear and unstandardized. Recently, efforts have been made to improve the pediatric approach to viper envenomation in European children. Several pediatric case reports in children were reported in literature, and a pediatric grading severity score and electronic clinical tool (VipGrade^®) were created to better manage this issue. However, larger studies are needed to validate these pediatric tools. This narrative review focuses on the clinical characteristics and management of European snake envenomation in children.

Background and Purpose: Medulloblastoma (MB) represents the predominant intracranial neoplasm observed in pediatric populations, characterized by a five-year survival rate ranging from 60% to 80%. Anticipating the prognostic outcome of medulloblastoma in children prior to surgical intervention holds paramount significance for informing treatment modalities effectively. Radiomics has emerged as a pervasive tool in both prognostic anticipation and therapeutic management across diverse tumor spectra. This study aims to develop a radiomics-based prediction model for the prognosis of children with MB and to validate the contribution of radiomic features in predicting the prognosis of MB when combined with clinical features. Materials and Methods: Patients diagnosed with medulloblastoma at our hospital from December 2012 to March 2022 were randomly divided into a training cohort (n = 40) and a test cohort (n = 41). Regions of interest (ROIs) were manually drawn on T1-weighted images (T1WI) along the boundary of the tumor, and radiomic features were extracted. Radiomic features related to survival prognosis were selected and used to construct a radiomics model. The patients were classified into two different risk stratifications according to the Risk-score calculated from the radiomics model. The log-rank test was used to test the difference in survival between the two stratifications to verify the classification value of the radiomics model. Clinical features related to the prognosis were used to construct a clinical model or clinical–radiomics model together with the radiomic features. Then, the clinical model, radiomics model, and clinical–radiomics model were compared to validate the improvement of radiomics in predicting the prognosis of medulloblastoma. The performance of the three models was evaluated with the C-index and the time-dependent AUC. Overall survival (OS) was defined as the time from receiving the operation to death or last follow-up. Results: A total of 81 children were included in this study. A total of five prognostic radiomic features were selected. The radiomics model could discriminate different risk hierarchies with good performance power in the training and testing datasets (training set p= 0.0009; test set p = 0.0286). Six clinical features associated with prognosis (duration of disease, risk hierarchy, dissemination, radiology, chemotherapy, and last postoperative white blood cell (WBC) level in CSF) were selected. The radiomic–clinical molecular features had better predictive value for OS (C-index = 0.860; Brier score: 0.087) than the radiomic features (C-index = 0.762; Brier score: 0.073) or clinical molecular characteristics (C-index = 0.806; Brier score: 0.092). Conclusions: Radiomic features based on T1-weighted imaging have predictive value for pediatric medulloblastoma. Radiomics has incremental value in predicting the prognosis of MB, and clinical–radiomics models have a better predictive effect than clinical models. Full article

Introduction: The American Academy of Pediatrics (AAP) published in 2017 new guidelines for the screening and management of hypertension in children containing different nomograms compared to the European guidelines, leading to a reclassification of blood pressure values, the consequences of which are still little investigated. The aim of our study was to evaluate the prevalence of high blood pressure values estimated with both the most recent American and European guidelines and to analyze the relationship of blood pressure increases with lifestyles and potentially risky behaviors in a school population in Western Sicily. Methods: On the occasion of the XV World Hypertension Day, blood pressure values of 1301 students aged between 13 and 18 were measured. Two questionnaires were administered, one relating to anamnestic data and anthropometric parameters and a second aimed at investigating lifestyle. For the diagnosis of increased blood pressure, both ESH and AAP criteria were considered. Results: The prevalence of elevated blood pressure was 7.5% according to ESH criteria and nearly twice as high using AAP criteria, with a more pronounced discrepancy in females. Individuals with elevated blood pressure were younger, exhibited higher body weight and BMI, and had an increased prevalence of overweight and obesity. Classification based on ESH criteria revealed higher alcohol and drug consumption among normotensive individuals. AAP criteria identified a higher proportion of males and greater height in the hypertensive group. Systolic blood pressure correlated significantly with height, weight, and BMI, with stronger associations in males, while diastolic pressure correlated with weight and BMI. Conclusions: To the best of our knowledge, our study is the only one to analyze the prevalence of increased blood pressure and its relationship with lifestyle factors and anthropometric data in adolescence in our region. Our study confirms that elevated blood pressure is common in adolescence, with higher prevalence using the 2017 AAP criteria than ESH guidelines. Full article

Background/Objectives: This study assesses parent reports of adolescent- and parent-level factors related to friendships among adolescents with asthma. This study serves to inform physicians and other health care professionals of factors related to difficulties making friends for adolescents with asthma, providing information from parent reports to identify risk and resilience factors related to friendships. Methods: Adolescents aged 12–17 years with current asthma from the 2022 National Survey of Children’s Health (NSCH) were selected for the study (n = 1812). A weighted logistic regression analysis was performed to explore predictors related to making and keeping friends. Adolescent-level predictors were asthma severity, allergies, body mass index, having behavioral problems, and adolescent sex and race/ethnicity (non-Hispanic White, and others, including Hispanic). Parent-level predictors were parent stress and coping. Results: Adolescents who were female, non-Hispanic White, had moderate/severe asthma symptoms, had current allergies, were overweight, and had behavioral problems were more likely to have difficulty making and keeping friends than adolescents who were male, non-White, had mild asthma, did not have allergies, were a normal weight or underweight, and did not have behavioral problems. Parents who reported difficulty coping with parenthood and its associated stressors were more likely to report that their adolescents had difficulty making friends. Conclusions: Pediatric moderate-to-severe asthma patients whose parents had difficulty coping with stress were more likely to exhibit greater difficulty making and keeping friends. Health care professionals managing these patients should incorporate questions into their history that address behavioral problems and parental household stress growing up to determine optimal strategies for improving friendship relationships. Whether this strategy leads to better asthma control and outcomes requires further investigation. In future studies, case studies with information about changes in friendships over time for adolescents with asthma should be carried out. The case studies could potentially highlight social strategies to use to improve friendship skills, and ultimately friendship-making for this vulnerable group. Full article

Background: Maternal phenylketonuria (PKU), a metabolic disorder caused by defective phenylalanine hydroxylase activity, requires strict lifelong dietary management to prevent toxic phenylalanine accumulation. During pregnancy, non-adherence to a low-phenylalanine diet can lead to maternal PKU syndrome, resulting in severe neonatal complications, including microcephaly, congenital heart defects, and growth restrictions. Despite advances in metabolic management and preconception care guidelines, adherence remains a significant challenge, particularly among adults transitioning out of pediatric care. This case report examines the clinical consequences of dietary non-adherence in maternal PKU, highlighting the importance of preconception education, metabolic monitoring, and multidisciplinary care in preventing adverse neonatal outcomes. Methods: Using the CARE guidelines, we present the clinical course of a male neonate born to a mother with untreated PKU. Results: The analysis incorporates maternal dietary history, prenatal care details, and neonatal outcomes. Additionally, a review of current literature on maternal PKU management and outcomes contextualizes the findings. The neonate, delivered at 38 weeks via cesarean section, exhibited low birth weight (2150 g), severe microcephaly (head circumference: 28 cm), microphthalmia, and septal heart defects. Maternal dietary non-adherence, beginning in late adolescence, contributed to significantly elevated phenylalanine levels during pregnancy (>20 mg/dL). Prenatal care was initiated in the 23rd week of gestation, delaying dietary intervention. The mother reported limited understanding of the teratogenic risks associated with poor dietary control, which was compounded by gaps in preconception counseling and care continuity. Conclusions: This case underscores the critical need for comprehensive preconception education and lifelong metabolic management for women with PKU. Early and sustained dietary adherence is essential to mitigate neonatal risks. Public health initiatives should prioritize access to preconception care, enhance patient education, and establish robust multidisciplinary support systems to optimize maternal and neonatal outcomes. Addressing barriers such as delayed care initiation and limited dietary support can significantly reduce the burden of maternal PKU syndrome. Full article
