Purpose: Our understanding of the influence of preterm birth and related perinatal exposures on early brain development is limited, hampering personalized optimization of neuroprotective strategies. This study assesses the effect of gestational age (GA) at birth on brain volumes at term-equivalent age (TEA) in infants without overt brain injury born across the GA spectrum. Methods: A cohort of infants born across the GA spectrum (25–40 weeks’ gestation) underwent 3T brain MRI around TEA (40–46 weeks postmenstrual age). Eight brain regions, intracranial and total tissue volumes were segmented using MANTiS (morphologically adaptive neonatal tissue segmentation toolbox). Segmentations were visually quality-checked and excluded if segmentation failed. Absolute TEA volume in relation to GA was assessed using univariate and multivariate (correction for postmenstrual age) linear regression analysis. Statistical significance was set at p < 0.05. Post hoc scatter plots of brain volumes relative to intracranial volumes were created. Results: Fifty infants were included (mean GA = 35.0 [SD = 3.3, range = 25.7–40.1] weeks). A higher GA at birth was significantly related to lower cerebrospinal fluid (p = 0.004) and amygdala (p = 0.02) volumes; no significant relation was found between GA and other volumes. Post hoc analyses showed positive trends between GA and several brain structures, including total brain tissue, cortical gray matter, deep gray matter, hippocampus, cerebellum and brainstem volumes. Conclusions: Our results suggest that GA has an effect on TEA brain volumes that is independent of brain lesions, with lower GA being associated with smaller brain tissue volumes and significantly larger cerebrospinal fluid volume. Preterm birth and related exposures may thus affect early brain growth and contribute to neurodevelopmental challenges encountered by preterm-born children. Full article

Shaken Baby Syndrome (SBS) is one of the primary causes of fatal head trauma in infants and young children, occurring in about 33 per 100,000 infants annually in the U.S., with mortality rates being between 15% and 38%. Survivors frequently endure long-term disabilities, such as cognitive deficits, visual impairments, and motor dysfunction. Diagnosing SBS remains difficult due to the lack of visible injuries and delayed symptom onset. Existing detection methods—such as neuroimaging, biomechanical modeling, and infant monitoring systems—cannot perform real-time detection and face ethical, technical, and accuracy limitations. This study proposes an inertial measurement unit (IMU)-based detection system enhanced with machine learning to identify aggressive shaking patterns. Findings indicate that wearable-based motion analysis is a promising method for recognizing high-risk shaking, offering a non-invasive, real-time solution that could minimize infant harm and support timely intervention.

Background and Objectives: The long-term renal and cardiovascular effects of neonatal acute kidney injury (AKI) in preterm infants remain unclear. This study investigated whether neonatal AKI leads to persistent subclinical kidney injury and blood pressure changes in school-aged children born preterm. Methods: In this prospective cohort, preterm-born children (≤35 weeks’ gestation) with (n = 19) and without (n = 38) neonatal AKI were evaluated at 7–12 years. A term-born control group (n = 44) was included for biomarker comparison. Assessments included perinatal data, anthropometry, office and ambulatory blood pressure monitoring (ABPM), and renal ultrasonography. Kidney function was evaluated using serum creatinine (sCr), cystatin C, and estimated glomerular filtration rate (eGFR). Tubular injury was assessed using urinary kidney injury molecule-1/Cr (KIM-1/Cr), neutrophil gelatinase-associated lipocalin/Cr (NGAL/Cr), and trefoil factor 3/Cr (TFF3/Cr) ratios, as well as serum TFF3. Results: Conventional kidney function markers were similar among groups. However, the AKI group had higher serum cystatin C, lower cystatin C–based eGFR, and elevated urinary KIM-1/Cr and NGAL/Cr compared to no-AKI and term controls. Serum TFF3 was also higher in the AKI group. ABPM revealed higher nocturnal systolic blood pressure and blood pressure load in the AKI group. Kidney size did not differ between preterm subgroups. Conclusions: Neonatal AKI in preterm infants is associated with subtle alterations and potential renal stress or injury at school age, detectable only with sensitive biomarkers and ABPM. Further prospective studies are needed to validate these biomarkers and determine their role in predicting long-term outcomes in preterm infants with neonatal AKI. Full article

Background/Objectives: Providing appropriate treatment for pediatric patients after traffic accidents remains a significant challenge. Furthermore, limited studies have validated the long-term effectiveness and safety of integrative Korean medicine treatment (IKMT) based on follow-up periods of 6 months or longer for pediatric patients. Methods: A retrospective chart review was conducted, focused on children aged 0–6 years who visited one of seven Korean medicine hospitals after traffic accident injuries and received IKMT between 1 January 2019 and 30 June 2023. The primary outcome was the Numeric Rating Scale (NRS) scores of chief complaints, and the secondary outcomes were quality of life, adverse events, and satisfaction with IKMT. Statistical analyses were conducted using paired t-tests and descriptive statistics, with a significance level of 5%. Results: Sixty-four participants were included in the retrospective chart review, and fifty-seven guardians responded to the surveys (mean age: 4.84 ± 1.26 years; mean duration of treatment: 19.20 ± 25.38 days). Among the immediate symptoms after the accidents, flashbacks and intrusive symptoms as well as nightmares and crying were the most common (50.9%). Following treatment, the NRS scores for flashbacks and intrusive symptoms and for nightmares and crying showed meaningful improvements from the time right after the accidents to the survey period. Follow-up confirmed that quality of life scores on all dimensions corresponded with those of healthy children. Nine adverse events were reported, and the participants fully recovered without the need for additional treatment. Furthermore, 91.2% of the survey respondents were satisfied with IKMT. Conclusions: IKMT was effective and safe for alleviating the post-accident symptoms in infants and young children aged 0–6 years involved in traffic accidents. Full article

Background: Congenital insensitivity to pain with anhidrosis (CIPA) is a rare genetic disorder, often leading to injuries and serious infections. In 2018, we established a multidisciplinary clinic (MDC) to provide structured, proactive care. We assessed the MDC’s impact on hospitalizations, surgeries, and infection rates. Methods: A retrospective study of genetically confirmed CIPA patients, treated from 2014 to 2024. Data from electronic medical records were compared between the pre-MDC (2014–2017) and post-MDC (2018–2024) periods. The core MDC team includes an infectious disease specialist, orthopedic surgeon, and nurses. The patients are stratified according to their carriage of resistant organisms and are managed using strict infection control measures. Follow-ups are scheduled routinely or as needed. Treatment is guided by clinical findings and culture results. Results: A total of 59 patients were included in the study. The baseline age did not differ significantly between the two periods. Hospitalization rates declined by 30.7% (from 57.7 to 40.0 per 1000 days), and clinic visits decreased by 42.9% (25.5 to 14.6). Overall surgical rates remained stable (2.8 to 2.7), with a 61.9% decrease in eye surgeries and a 130.5% increase in elective tooth extractions. Infection rates increased by 52% (from 6.6 to 10.1 per 1000 days). Conclusions: The implementation of the MDC bundle led to reduced hospitalizations, clinic visits, and eye surgeries, alongside the increased use of elective tooth extractions and culture testing. Closer monitoring and early infection management contributed to fewer severe complications. These findings support the value of structured, proactive multidisciplinary care in improving outcomes for children with CIPA. Full article

Background/Objectives: Elevated troponin levels are widely recognized as key biomarkers of myocardial injury and are frequently used in clinical decision making. However, not all instances of troponin elevation indicate true cardiac damage. In some cases, biochemical or immunological interferences may lead to false-positive results. These situations may lead to unnecessary diagnostic interventions and clinical uncertainty, ultimately impacting patient management negatively. This study aims to investigate the underlying mechanisms of false-positive troponin elevation in pediatric patients, focusing on factors such as macrotroponin formation, autoantibodies, and heterophile antibody interference. Methods: This retrospective study analyzed data from 13 pediatric patients who presented with elevated cardiac troponin levels between 2017 and 2024. Clinical evaluations included transthoracic echocardiography (TTE), electrocardiography (ECG), coronary computed tomography angiography (CTA), cardiac magnetic resonance imaging (MRI), and rheumatologic testing. Laboratory findings included measurements of cardiac troponins (cTnI and hs-cTnT) and pro-BNP levels. Results: Among 70 patients evaluated for elevated troponin levels, 13 (18.6%) were determined to have no identifiable cardiac etiology. The median age of these 13 patients was 13.0 years (range: 9–16), with 53.8% being female. The most common presenting complaints were chest pain (53.8%) and palpitations (30.8%). TTE findings were normal in 61.5% of the patients, and all patients had normal coronary CTA and cardiac MRI findings. Although initial troponin I levels were elevated in all cases, persistent positivity was observed up to 12 months. Median cTnI levels were 1.00 ng/mL (range: 0.33–7.19) at week 1 and 0.731 ng/mL (range: 0.175–4.56) at month 12. PEG precipitation testing identified macrotroponin in three patients (23.1%). No etiological explanation could be identified in 10 cases (76.9%), which were considered idiopathic. All patients had negative results for heterophile antibody and rheumatologic tests. Conclusions: When interpreting elevated troponin levels in children, biochemical interferences—especially macrotroponin—should not be overlooked. This study emphasizes the diagnostic uncertainty associated with non-cardiac troponin elevation. To better guide clinical practice and clarify false positivity rates, larger, multicenter prospective studies are needed. Full article

Echovirus 18, a member of the B group of enteroviruses, is a significant etiological agent of aseptic meningitis and viral encephalitis in children. In this study, we investigated the pathogenicity of E18 by establishing a mouse infection model after comparing various mouse strains and injection methods. Two-day-old IFNAR1 knockout mice infected with clinical isolates of E18 exhibited symptoms such as lethargy, hind limb paralysis, and even mortality. Similarly, some two-day-old C57BL/6J mice displayed comparable symptoms; however, the incidence was lower than that observed in IFNAR1 knockout mice. No similar symptoms were noted in any Balb/c mice. Significant pathological changes were observed in skeletal muscle, brain tissue, and other organs of symptomatic mice; among these tissues, skeletal muscle demonstrated the highest viral load. The established infection model using two-day-old IFNAR1 knockout mice provides valuable insights into further investigations regarding its pathological injury mechanisms as well as the protective effects conferred by antibodies.

The aim of this study is to assess endothelial progenitor cells (EPCs) and circulating endothelial cells (CECs) at the time of type 1 diabetes (T1D) recognition concerning patients’ clinical state, remaining insulin secretion, and further partial remission (PR) occurrence. We recruited 45 children that were admitted to hospital due to newly diagnosed T1D (median age 10.8 yrs), and 20 healthy peers as a control group. EPC and CEC levels were measured at disease onset in PBMC isolated from whole peripheral blood with the use of flow cytometry. Clinical data regarding patients’ condition, C-peptide secretion, and further PR prevalence were analyzed. T1D-diagnosed patients presented higher EPC levels than the control group (p = 0.026), while no statistical differences in CEC levels and EPC/CEC ratio were observed. Considering only T1D patients, those with better clinical conditions presented lower EPCs (p = 0.021) and lower EPC/CEC ratios (p = 0.0002). Patients with C-peptide secretion within a normal range at disease onset presented lower EPC/CEC ratios (p = 0.027). Higher levels of EPCs were observed more frequently in patients with higher glucose, decreased fasting C-peptide, and lower stimulated C-peptide (all p < 0.05). The presence of DKA was related to higher EPC/CEC ratios (p = 0.034). Significantly higher levels of CECs were observed in patients who presented partial remission of the disease at 6 months after diagnosis (p = 0.03) only. In the study group, positive correlations of CECs with age, BMI at onset, and BMI in following years were observed. EPC/CEC ratios correlated positively with glucose levels at hospital admission and negatively with age, BMI, pH, and stimulated C-peptide level. We reveal a new potential for the application of EPCs and CECs as biomarkers, reflecting both endothelial injury and reconstruction processes in children with T1D. There is a need for further research in order to reduce cardiovascular risk in children with T1D. Full article

Background: The consequences of injuries resulting from accidents are among the most common health disorders in children. A scar forms at the site of the injury. In the treatment of scars, not all methods used in adults can be used in children. The authors attempted to assess the effectiveness of using KT kinesiology taping on scars in children. The aim of the work is to assess the effect of KT on the treatment of keloid, hypertrophic scars, and postoperative adhesions in children. Methods: The study included 30 patients aged 4 to 10 years. The subjects were divided into three groups: group G1-9 patients with keloid scars, group G2-14 with hypertrophic scars, group G3-7 with postoperative adhesions. The patients underwent kinesiology taping for 8 weeks. The analyzed parameters were determined using the VSS scale and ultrasonography. Results: The analysis of the VSS scale results in relation to the type of scars showed a significant (p < 0.001) downward trend in the measured parameters for keloid and hypertrophic scars. Analysis of ultrasound results in relation to the type of scars showed a significant (p < 0.001) downward trend in the measured parameters, comparing parameters I and II for all types of scars. Conclusions: Kinesiology taping significantly changes the following scar parameters: deformability, pigmentation, and perfusion in the case of keloid and hypertrophic scars. Full article

Background: Trauma-related injuries are among the most common reasons for paediatric hospital presentations and represent a substantial component of orthopaedic care. Their management poses unique challenges due to ongoing skeletal development in children. While most reported fractures occur at home or during sports, prior studies have primarily used data from urban European populations, limiting the relevance of their findings for rural and regional settings. Urban-centred research often informs public healthcare guidelines, treatment algorithms, and infrastructure planning, introducing a bias when findings are generalised outside of metropolitan populations. This study addresses that gap by analysing fracture data from two rural trauma centres in New South Wales, Australia. This study assesses paediatric fractures resulting from severe injury mechanisms in rural areas, identifying common fracture types, underlying mechanisms, and treatment approaches to highlight differences in demographics. These findings aim to cast a light on healthcare challenges that regional areas face and to improve the overall cultural safety of children who live and grow up outside of the metropolitan trauma networks. Methods: We analysed data from two major rural referral hospitals in New South Wales (NSW) for paediatric injuries presenting between 1 January 2018 and 31 December 2022. This study included 150 patients presenting with fractures following severe mechanisms of injury, triaged into Australasian Triage Scale (ATS) categories 1 and 2 upon initial presentation. Results: A total of 150 severe fractures were identified, primarily affecting the upper and lower limbs. Males presented more frequently than females, and children aged 10–14 years old were most commonly affected. High-energy trauma from motorcycle (dirt bike) accidents was the leading mechanism of injury among all patients, and accounted for >50% of injuries among 10–14-year-old patients. The most common fractures sustained in these events were upper limb fractures, notably of the clavicle (n = 26, 17.3%) and combined radius/ulna fractures (n = 26, 17.3%). Conclusions: Paediatric trauma in regional Australia presents a unique and under-reported challenge, with high-energy injuries frequently linked to unregulated underage dirt bike use. Unlike urban centres where low-energy mechanisms dominate, rural areas require targeted prevention strategies. While most cases were appropriately managed locally, some were transferred to tertiary centres. These findings lay the groundwork for multi-centre research, and support the need for region-specific policy reform in the form of improved formal injury surveillance, injury prevention initiatives, and the regulation of under-aged off-road vehicular usage.

Background: The COVID-19 pandemic has had a profound impact on pediatric mental health, contributing to a global surge in psychiatric emergencies among children and adolescents. This study aimed to evaluate trends in pediatric emergency department (PED) visits for three key psychiatric conditions—anxiety disorders (ADs), self-injury behaviors (SIBs), and psychomotor agitation (PMA)—before and after the onset of the COVID-19 pandemic. Methods: We conducted a retrospective observational study at a tertiary pediatric hospital in Italy, analyzing all psychiatric presentations to the PED from 1 January 2018 to 31 December 2024. The data were divided into pre-COVID and post-COVID periods and included patient demographics, recurrence of visits, clinical features, hospital admissions, and pharmacological management. Diagnoses were confirmed by chart review. Results: Of 233,867 total PED visits, 1082 were due to primary psychiatric concerns. A marked increase in visits was observed postCOVID: SIB incidence rose from 3.6 to 15.1 per 10,000 visits (p < 0.0001), PMA from 9.4 to 17.8 (p < 0.0001), and AD from 17.7 to 21.6 (p = 0.018). SIB cases showed increased recurrence (from 3.4% to 27.4%, p = 0.004) and greater pharmacological intervention, whereas PMA was associated with a rise in heteroaggression (from 14.3% to 39.8%, p < 0.0001). Pharmacological treatment remained largely consistent, with benzodiazepines and neuroleptics most frequently used. The emerging use of intranasal ketamine was noted in select cases. Conclusions: This study highlights the increasing burden of pediatric psychiatric emergencies in the wake of the COVID-19 pandemic. The findings underscore the urgent need to implement standardized emergency care protocols, strengthen outpatient mental health services, and develop pediatric-specific pharmacological guidelines to improve outcomes in this vulnerable population.

Suicide in children is a major global health crisis, with profound impacts on families, friends, and society. Understanding ways to ameliorate the rate of suicide attempt (SA) is critical given that it is a key factor in predicting future suicide risk. SA is the deliberate act of causing physical injury to oneself with the intent of death. The incidence of SA may be influenced by physical activity (PA). PA includes bodily movement via skeletal muscles that results in energy expenditure and physical fitness. While there is evidence to suggest that PA improves dysregulation of the parasympathetic nervous system which underpins the physiology of suicidal behaviour, evaluating the impact of PA on SA in children is required. Objectives: This systematic review aims to determine the relationship between PA and SA in children to inform alternative preventative and interventional strategies. Methods: This systematic review was registered with PROSPERO: CRD42023389415. Eight electronic databases were systematically searched. References were transferred to Covidence software for title and abstract screening and full text review were performed based on eligibility criteria: (1) children aged 6–18 years old; (2) participated in PA (individual, group exercise, or team sports); and (3) examined SA as a dependent variable. The JBI Checklist was used to measure the quality and level of bias of included studies. Results: Of the 2322 studies identified, 21 were included in the final analysis of the review. Twenty studies were cross-sectional in design, and one implemented a prospective study design. Thirteen studies (61.9%) yielded statistically significant results, indicating that increased PA, particularly team sport, may be associated with reduced odds of SA. There was some evidence to suggest that certain intensities and frequencies of PA may be beneficial to some and detrimental to other subgroups. Conclusions: The results suggest that PA may reduce the risk of suicide attempts. Although PA may be associated with reduced SA in children, future research is required, which (1) uses standardised outcome variables; (2) adopts longitudinal and experimental study designs; (3) explores qualitative research to determine distinctive factors that influence participation in PA not captured by quantitative research; and (4) examines different target populations such as children with a broad range of mental health issues.

Metabolic dysfunction-associated steatotic liver disease (MASLD) is the most common chronic progressive hepatopathy in children, and the identification of non-invasive biomarkers is urgently needed. Growth differentiation factor 15 (GDF15) was associated with MASLD in adults. In this study, we investigated the circulating and hepatic levels of GDF15 and their association with liver damage in pediatric MASLD and in a murine model. This observational study included 158 children with biopsy-proven MASLD. Patients with MASLD were categorized into two groups based on steatohepatitis (MASH) presence and evaluated for GDF15 circulating levels, while GDF15 hepatic levels were assessed only in a subset of patients. Children with MASLD exhibited higher levels of circulating GDF15 compared to the controls. Moreover, the MASH subgroup had significantly higher values of GDF15 compared to the Not-MASH subgroup. The GDF15 levels in the MASH subgroup showed a positive correlation with fibrosis. Finally, the hepatic expression of the GDF15 gene correlated with GDF15 circulating levels and with the hepatic expression of the COL1A1 and COL3A1 genes in 15 children with MASLD. In conclusion, our study demonstrated that GDF15 levels are associated with liver damage, reinforcing the potential role of GDF15 as a biomarker for MASLD-related fibrosis in children. Full article

Background: Unintentional injuries are the primary cause of death and disability among children. This study aimed to examine the current status of home environments for children aged 0–6 years in the Shanghai area of China and assess the factors that pose safety hazards for unintentional injuries within households. Methods: A cross-sectional survey was carried out in Shanghai between November 2021 and October 2023. Results: Parents from 1825 families, with 929 (50.90%) boys and 896 (49.10%) girls, participated in this research. In all, 752 children (41.21%) experienced unintentional injuries. The home environment posed a high risk of unintentional injuries in 1008 families (55.23%), medium risk in 381 families (20.88%), and low risk in 436 families (23.89%). The results showed a negative correlation between the occurrence of unintentional injuries and the status of the family environment; children in families with high-risk home environments were more likely to experience unintentional injuries (odds ratio [OR] = 1.490, confidence interval [CI] = 1.216–1.826), fall injuries (OR = 1.605, CI = 1.268–2.031), and external injuries (OR = 1.578, CI = 1.159–2.148). Conclusions: Parents should enhance their safety awareness by focusing on potential hazards at home and taking appropriate measures to improve the home environment, thereby creating a safe and comfortable setting for the healthy growth of their children.

Background: Neonates, particularly those born prematurely or with low birth weight, face an elevated risk of developing Acute Kidney Injury (AKI) due to various factors. Perinatal and maternal considerations, often linked to preterm delivery, contribute to this heightened risk. Methods: A retrospective study of neonates admitted to the intensive care unit at a single Israeli Hospital who were diagnosed as having AKI. The study includes follow-up data on these children. Results: During the study period, 971 neonates were admitted to the Pediatric Intensive Care Unit (PICU), and 47 cases had a documented diagnosis of AKI. Thirty-four of them had available long-term data and were included in this analysis. A total of 13 out of 26 subjects with available blood pressure measurements had high blood pressure for their age percentile compatible with the definition of hypertension, and 6 out of 34 (17.6%) had proteinuria. Conclusions: These findings underscore the importance of increased clinical awareness and structured long-term follow-up for neonates who experience AKI. Full article
