The prevalence of depressive disorder among adolescents is rising, causing serious harm to families and society. Examining risk behaviors such as gaming addiction, non-suicidal self-injury, and suicidal behaviors resulting from adolescent depressive disorder in light of psychosocial and pathophysiological perspectives, along with in-depth exploration of diagnostic and therapeutic dilemmas—including insidious onset, high comorbidity, and difficulties in differential diagnosis—helps build a multidimensional intervention system encompassing psychological, pharmacological, and physical therapies. It also provides a theoretical basis for promoting multicenter cohort studies and establishing a comprehensive prevention and control model linking families, schools, and hospitals. This paper systematically outlines the current epidemiological status, comorbidity spectrum, and clinical pathways for early identification and comprehensive intervention in adolescent depressive disorder.

Objective To analyze the Bayesian network of harsh parenting, experiential avoidance, and adolescent short video addiction risk, identify key nodes, and provide precise recommendations for intervention. Methods In March 2025, the Harsh Parenting Scale, Experiential Avoidance Scale, and Short Video Addiction Scale were administered to 1 594 adolescents. Network analysis was performed using JASP 0.95.4, and key nodes were identified via centrality estimation. Results The core nodes of harsh parenting, experiential avoidance, and short video addiction risk were "I am hit with hands or kicked when I do something wrong or make my parents angry" (expected influence = 0.301), "Certain feelings make me feel scared" (expected influence = 0.684), and "Withdrawal" (expected influence = 1.222), respectively. Conclusions Interventions targeting these key nodes serve as an important reference for mitigating the impact of harsh parenting, experiential avoidance, and short video addiction risk on adolescents.

Vasovagal syncope (VVS) is the most common cause of neurally mediated syncope in children. Recurrent syncope severely affects physical and mental health and may lead to unintentional injury. Based on international and domestic guidelines and clinical practice experience, standardized recommendations for the diagnosis and treatment of pediatric VVS are proposed. Management of VVS should be individualized, and non-pharmacological interventions, including lifestyle modifications, are the cornerstone for both classic and malignant VVS. Pharmacological therapy is recommended for children with VVS who have recurrent syncopal episodes, are at risk of trauma, or respond poorly to non-pharmacological interventions. For children in whom the head-up tilt test induces asystole, pacemaker implantation is not recommended as first-line therapy. In malignant VVS with recurrent syncope despite conventional treatment, pacemaker implantation may be considered after specialist evaluation. Data on cardioneuroablation in children are limited, and long-term follow-up is required.

Early screening, diagnosis, and intervention for congenital muscular torticollis (CMT) in infants are crucial for improving clinical outcomes. However, in China, limited awareness of CMT among child healthcare institutions and caregivers, as well as inconsistent professional standards among rehabilitation personnel, pose significant challenges to the effective diagnosis and management of CMT. The "Physical therapy management of congenital muscular torticollis: a 2024 evidence-based clinical practice guideline from the American Physical Therapy Association Academy of Pediatric Physical Therapy" includes 17 action statements, primarily addressing the prevention, identification, assessment, and intervention of CMT. This guideline is expected to facilitate early detection of CMT in infants, enhance the treatment capabilities of physical therapists, and improve clinical outcomes. This article provides an interpretation of the guideline in the context of the current status of CMT diagnosis and management in China, aiming to offer a reference for improving the ability of primary child healthcare providers and physical therapists to recognize and manage CMTropriately.

Pediatric chronic myeloid leukemia (CML) is more aggressive than adult CML, with unique molecular characteristics and a higher propensity for lymphoid blast crisis. The application of tyrosine kinase inhibitors (TKIs) has significantly improved the prognosis of pediatric CML. Based on international consensus and clinical experience, this article proposes standardized diagnosis and treatment recommendations for pediatric CML, covering initial therapy selection, efficacy evaluation, drug switching, and management of adverse effects. Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is recommended only for patients with disease progression or failure of multiple lines of TKI therapy. For children newly diagnosed with CML in accelerated phase, high-dose imatinib or second-generation TKIs are recommended as first-line therapy. Those achieving optimal responses should continue maintenance therapy, while non-responders require switching to alternative TKIs and consider allo-HSCT. For blast-phase CML, induction therapy requires a combination of TKIs and chemotherapy, with allo-HSCT serving as the core curative intervention. This article highlights common but challenging problems (poor response, drug intolerance, and disease progression) in pediatric CML treatment using three typical cases, aiming to optimize treatment strategies. Furthermore, the goal of achieving treatment-free remission needs to be further addressed through multi-center clinical studies.

Peripherally inserted central catheter (PICC) placement is an essential routine procedure in neonatal intensive care units and an important life-support technology. In recent years, point-of-care ultrasound-guided catheter insertion and ultrasound localization of catheter tips have been widely applied in neonatal practice and demonstrate clear advantages over traditional methods. This guideline was developed on the basis of currently available evidence and the practical experience of domestic experts, and it is tailored to the Chinese context. It provides clinical practice recommendations for ultrasound-monitored vascular selection, ultrasound-guided PICC cannulation, and ultrasound localization of the PICC tip. In total, 22 recommendations addressing 10 key clinical questions are presented, covering pre-insertion vascular selection, intra-procedural ultrasound-guided localization, post-insertion dynamic monitoring, and troubleshooting of difficult scenarios. The aim is to promote standardized application of this technology in neonatal intensive care units in China, reduce complications, and improve safety.

In order to effectively assist primary healthcare providers in standardizing the screening of congenital heart disease (CHD), enabling early identification of critical CHD in neonates, and ensuring timely referral to reduce the risk of complications and mortality, the Subspecialty Group of Neonatology, Society of Pediatrics,Chinese Medical Association has led a team of experts to integrate the latest clinical research advances on CHD. Following comprehensive discussions, the "Expert consensus on the diagnosis and treatment of common neonatal diseases in primary healthcare institutions: congenital heart disease (2025)" was developed. The consensus covers eight common clinical questions faced by primary healthcare providers regarding CHD and provides 13 recommendations.

Ureaplasma urealyticum (UU) is a common pathogen colonizing or infecting the neonatal respiratory tract. It can be vertically transmitted from mother to infant, irrespective of the duration of premature rupture of membranes and the mode of delivery. UU infection is an important factor contributing to preterm birth and low birth weight and is closely associated with adverse outcomes such as bronchopulmonary dysplasia and neurodevelopmental impairment. Given the immaturity of neonatal immune and organ systems, pharmacologic treatment must balance efficacy and safety. Currently, no unified standard regimen has been established for the treatment of neonatal UU infection. This review summarizes pharmacotherapeutic options for neonatal UU infection to inform clinical practice.

Seizures are common clinical emergencies in neonatology, potentially leading to severe complications and directly impacting the neurodevelopmental prognosis of the infants with this condition. For primary healthcare providers, key clinical challenges include standardized emergency management, precise clinical diagnosis and treatment, and accurate assessment of referral indications. To assist primary healthcare providers in the prompt identification and standardized management of neonatal seizures, the Subspecialty Group of Neonatology, Society of Pediatrics, Chinese Medical Association organized a panel of experts to develop the "Guideline for the diagnosis and treatment of common neonatal diseases in primary healthcare institutions: neonatal seizures (2025)", based on the latest clinical evidence and expert consensus. This guideline provides primary healthcare providers with 17 recommendations addressing nine common clinical questions in neonatal seizures.

This review summarizes the mechanisms, assessment, and clinical management of comorbid constipation in ASD and aims to provide a reference for comprehensive interventions in ASD.

With continuous advancements in neonatal care in China, the survival rate of extremely preterm infants has markedly increased in recent years. However, the proportion of voluntary withdrawal of treatment for extremely preterm infants remains relatively high. To further improve the overall treatment success rate for extremely preterm infants in Hunan Province, the Hunan Neonatal Medical Quality Control Center, in collaboration with the Perinatal Committee of the Hunan Medical Association, organized experts to develop recommendations on antenatal counseling for extremely preterm infants. These recommendations aim to standardize antenatal counseling procedures, enhance the scientific rigor and consistency of clinical decision-making, and improve survival outcomes.

Osteogenesis imperfecta (OI) is a rare genetic skeletal disorder most commonly caused by variants in COL1A1 and COL1A2, which encode type I collagen. It is characterized by increased bone fragility, recurrent fractures, and skeletal deformities that adversely affect quality of life. With advances in genetic testing and molecular pathophysiology, diagnosis has evolved from traditional imaging-based assessment to comprehensive evaluation guided by genotype-phenotype correlations. Early diagnosis and standardized management are crucial for improving prognosis; however, the rarity of OI and rapid technological progress make it challenging to keep pace with evolving diagnostic and therapeutic strategies. This article discusses the genetic and pathophysiological mechanisms, recent advances in diagnosis and treatment, and key points in the management of OI, aiming to provide up-to-date reference information for OI care and clear, actionable guidance for clinicians.

Duchenne muscular dystrophy (DMD) is an X-linked recessive neuromuscular disorder characterized primarily by progressive degeneration and necrosis of skeletal muscle, resulting from mutations in the Dystrophin gene. Patients with DMD typically present with progressive muscle weakness and atrophy during childhood. Currently, available treatment options for DMD remain limited and their efficacy is suboptimal. This review aims to provide a systematic overview of recent advances in therapeutic strategies for DMD, including an analysis of the mechanisms underlying various treatment approaches, outcomes from clinical trials, and their potential clinical applications, in order to inform and guide clinical decision-making.

Mosquito-borne viruses, including dengue virus (DENV), chikungunya virus (CHIKV), and Zika virus (ZIKV), pose major threats to public health in tropical and subtropical regions worldwide. Neonates are particularly vulnerable, and the associated disease burden has drawn increasing attention. Routes of neonatal infection include vertical mother-to-child transmission (transplacental and peripartum) and postnatal mosquito bites. Clinical manifestations are often nonspecific; a proportion of cases may progress to central nervous system infection, hemorrhagic disease, or long-term neurodevelopmental impairment, with serious consequences for survival and quality of life. Although China has issued prevention and control guidelines for adults and pregnant women, systematic clinical guidance tailored to neonates remains lacking. In response, the Perinatal Group of the Pediatric Branch of the Chinese Medical Doctor Association convened a multidisciplinary panel to develop this expert consensus, integrating the latest international evidence with China's practical prevention and control experience. The consensus addresses epidemiology; the effects of maternal infection on fetuses and neonates; clinical manifestations; diagnosis and differential diagnosis; early warning indicators of severe disease; therapeutic strategies and supportive care; and prevention and maternal-infant management. It aims to provide evidence-based, standardized, and practical guidance for frontline clinicians managing neonatal mosquito-borne viral infections.

Objective To analyze the serum metabolomic changes of preterm infants with bronchopulmonary dysplasia (BPD) at postmenstrual age (PMA) 36 weeks, screen potential biomarkers and associated metabolic pathways, and assess their relationship with short-term respiratory outcomes. Methods A retrospective case-control study was conducted. Infants with gestational age 28-32 weeks admitted to the Children's Hospital Affiliated to Zhengzhou University from January to December 2024 were included. Twenty infants with BPD and 20 gestational age-, birth weight-, and sex-matched non-BPD preterm infants were included. Serum collected at PMA 36 weeks was subjected to untargeted metabolomics analysis, and associations with short-term respiratory outcomes were analyzed. Results Thirteen potential biomarkers distinguishing BPD were identified (area under the curve >0.75, P<0.05). Eight biomarkers—including terephthalic acid, phosphatidylinositol, fumarate, and lysophosphatidic acid—were significantly upregulated (FC≥1.5), while five biomarkers, such as 7α-hydroxy-3-oxo-4-cholestenoate ester and phosphatidylcholine, were significantly downregulated (FC≤1/1.5). Pathway analysis indicated five pathways associated with BPD, including glycerophospholipid metabolism and phenylalanine metabolism. Dysregulation of glycerophospholipid and bile acid metabolism may affect adverse short-term respiratory outcomes in infants with BPD. Conclusions The 13 significantly different metabolites may serve as biomarkers for the diagnosis of BPD. Glycerophospholipid metabolism is associated with the occurrence of BPD and with adverse short-term respiratory outcomes.

Objective To evaluate the clinical utility and translational potential of a remote jaundice monitoring system for home-based screening of neonatal hyperbilirubinemia. Methods A prospective self-controlled study was conducted, enrolling 538 newborns with gestational age ≥35 weeks, birth weight ≥2 000 g, and postnatal age ≤14 days at the Women's Hospital of Nanjing Medical University from March to October 2023. Four screening protocols with different predictive indicators were developed based on the Chinese Neonatal Transcutaneous Hourly Bilirubin Nomogram. The effectiveness of the system was evaluated, and the feasibility of using the remote jaundice monitoring system in actual home settings was analyzed. Results A total of 538 paired transcutaneous bilirubin (TcB) and total serum bilirubin (TSB) measurements showed a strong correlation (r=0.85, P<0.001), with 95.0% (511/538) of samples within the 95% limits of agreement. Using TcB ≥ the 95th percentile as the predictive indicator, the system achieved 100% sensitivity, 46.2% specificity, and an area under the receiver operating characteristic curve of 0.731 (95%CI: 0.682-0.780). This approach could reduce unnecessary hospital visits by 41.4% (221/538). Conclusions The system integrates the QBH-801 transcutaneous bilirubinometer, intelligent early warning, and remote guidance services, establishing a closed-loop "hospital-to-home" management model. It demonstrates high safety and feasibility, with significant clinical translational value.

Objective To explore the relationship between frontal alpha asymmetry (FAA) assessed by electroencephalogram (EEG) and emotion dysregulation (ED) in children with attention deficit hyperactivity disorder (ADHD). Methods Children with ADHD admitted to Fuyang Women and Children's Hospital from September 2021 to December 2024 were prospectively enrolled (n=104). Based on the Achenbach Child Behavior Checklist (CBCL), participants were classified into an ED group (sum of three subscales <180; n=41) and a non-ED group (sum ≥180; n=63). Clinical data were collected, and the Chinese ADHD SNAP-IV parent version and the Weiss Functional Impairment Rating Scale-Parent Report were used. FAA was measured by EEG. Correlations between FAA in different regions and CBCL score were analyzed, and the predictive value of FAA for ED was evaluated with multivariable logistic regression and receiver operating characteristic curves. Results Compared with the non-ED group, the ED group had a higher proportion of the predominantly inattentive ADHD subtype, higher SNAP-IV total score, higher Weiss Functional Impairment Rating Scale-Parent Report total score, and higher FP1/FP2-FAA and C3/C4-FAA (P<0.05). FP1/FP2-FAA and C3/C4-FAA were negatively correlated with CBCL score (P<0.05). The multivariable logistic regression analysis showed that FP1/FP2-FAA and C3/C4-FAA were closely associated with ED in children with ADHD (P<0.05). The areas under the curve for predicting ED using FP1/FP2-FAA, C3/C4-FAA, and their combination were 0.827, 0.685, and 0.917, respectively (P<0.05), and the combined prediction had a higher area under the curve than either single marker (P<0.05). The FP1/FP2 FAA value in hyperactive-impulsive ADHD was lower than in combined-type ADHD and predominantly inattentive ADHD (P<0.05). Conclusions FP1/FP2-FAA and C3/C4-FAA are reliable neural markers of emotion dysregulation in children with ADHD, and their combination shows superior predictive performance. ADHD subtypes show distinct patterns of FAA-functional impairment associations.

Objective To develop dynamic prediction models based on multiple postnatal time points to support early diagnosis and individualized intervention for bronchopulmonary dysplasia (BPD) in preterm infants with gestational age < 32 weeks. Methods Clinical data of 472 preterm infants with gestational age <32 weeks admitted to the Second Xiangya Hospital of Central South University between January 2016 and November 2020 were retrospectively analyzed. Multivariable logistic regression was applied to develop five independent prediction models at postnatal days 1, 7, 14, 21, and 28. The performance of the models was assessed using the area under the receiver operating characteristic curve (AUC) and the Hosmer-Lemeshow test. Results Baseline characteristics such as gestational age and birth weight differed significantly between the BPD group (n=147) and the non-BPD group (n=325) (P<0.05). Predictors of BPD evolved across time points: on day 1, key predictors included gestational age, birth weight, Score for Neonatal Acute Physiology II (SNAP-II), invasive mechanical ventilation, and fraction of inspired oxygen >30%; by day 7, additional variables emerged, including fasting duration >2 days, mean feeding advancement rate <8.5 mL/(kg·d), neonatal respiratory distress syndrome, apnea of prematurity, and positive sputum culture; from day 14 onward, nutrition- and treatment-related indicators were incorporated additionally. The models demonstrated good discrimination at postnatal days 1, 7, 14, 21, and 28, with AUCs of 0.917, 0.927, 0.939, 0.944, and 0.968, respectively, and good calibration (Hosmer-Lemeshow P>0.05). Internal validation showed AUCs ranging from 0.899 to 0.958, indicating robust performance. Conclusions Dynamic postnatal prediction models incorporating indicators spanning perinatal factors, respiratory support, nutritional management, and therapeutic interventions demonstrate high predictive performance and facilitate dynamic risk assessment for BPD in preterm infants with gestational age < 32 weeks.

The prevalence of adolescent depressive symptoms has been rising, and maternal depression is a key predictor. This review synthesizes evidence on mechanisms of influence and on intervention research. The intergenerational transmission of risk from maternal depression appears more pronounced than that associated with paternal depression. At the biological level, genetic susceptibility and neurodevelopmental alterations underpin intergenerational transmission; at the social level, negative parenting practices and stressful family environments create a vicious cycle; at the psychological level, deficits in emotion regulation and insecure attachment amplify vulnerability to depression. Family-based interventions, including cognitive-behavioral therapy and family systems therapy, can mitigate intergenerational transmission. However, more longitudinal research is needed, and future work may integrate digital technologies to develop structured intervention protocols.

Objective To investigate the potential circular RNA (circRNA)-microRNA (miRNA)-messenger RNA (mRNA) immune regulatory network in childhood allergic asthma by analyzing microarray datasets. Methods GEO database was used to obtain the datasets of circRNA, miRNA, and mRNA from children with allergic asthma and healthy controls. The Limma package was used to identify differentially expressed circRNA (DEcircRNA), miRNA (DEmiRNA), and mRNA (DEmRNA). ENCORI and other tools were used to predict and construct the regulatory network of endogenous RNA. The DAVID database was used to perform GO and KEGG enrichment analyses, and CIBERSORT and Pearson were used to identify genes associated with immune cell infiltration. Results A total of 130 DEcircRNAs, 40 DEmiRNAs, and 802 DEmRNAs were identified between the asthma and control groups, and a regulatory network consisting of 12 circRNAs, 7 miRNAs, and 75 mRNAs was established. The GO analysis showed that the differentially expressed genes were mainly involved in the regulation of growth and development, and the KEGG analysis showed that they were mainly involved in the mTOR signaling pathway. The CIBERSORT analysis showed that compared with the control group, the asthma group had higher percentages of CD8⁺ T cells and resting NK cells and lower percentages of resting CD4⁺ memory T cells and activated mast cells. In addition, the Pearson correlation analysis identified six key mRNAs that were positively correlated with immune cell infiltration. Conclusions The ceRNA immune regulatory network constructed in this study provides a basis for research on the mechanism of childhood allergic asthma and potential therapeutic targets.

Objective To study the clinical and imaging features of children with influenza-associated encephalopathy (IAE), and to investigate the influencing factors for prognosis. Methods A retrospective analysis was conducted on the medical data (clinical data, laboratory examinations, imaging data, and prognosis) of 23 children with IAE who were diagnosed and treated in Children's Hospital of Nanjing Medical University from May 2022 to April 2023. Results Among the 23 patients, 18 (78%) had influenza A and 5 (22%) had influenza B. All patients had fever and encephalopathy, and 20 patients (87%) had seizures, while 11 patients (48%) had persistent convulsions. There were 10 patients (43%) with an increase in alanine aminotransferase, 14 (61%) with an increase in aspartate aminotransferase, and 18 (78%) with an increase in lactate dehydrogenase. Abnormal imaging findings were observed in 20 patients (87%), among whom 10 (43%) had acute necrotizing encephalopathy. All 23 patients received peramivir or oseltamivir. Of all patients, 12 (52%) achieved complete recovery, 5 (22%) had varying degrees of neurological dysfunction, and 6 (26%) died. Compared with the good prognosis group, the poor prognosis group had significantly higher levels of alanine aminotransferase, aspartate aminotransferase, and lactate dehydrogenase (P<0.05). Conclusions Fever and convulsions are the most common symptoms of children with IAE, and acute necrotizing encephalopathy is the most common clinical imaging syndrome. Increases in alanine aminotransferase, aspartate aminotransferase, and lactate dehydrogenase have a certain value in predicting poor prognosis.

Objective To investigate the readmission rate and risk factors for readmission due to hyperbilirubinemia in neonates with ABO hemolytic disease of the newborn (ABO-HDN), and to construct a risk prediction model for readmission. Methods Neonates diagnosed with hyperbilirubinemia due to ABO-HDN and hospitalized in the neonatal department between January 2021 and December 2023 were enrolled. Based on readmission status, neonates were divided into a readmission group and a control group. Clinical characteristics related to hyperbilirubinemia and risk factors for readmission were analyzed. Subsequently, a prediction model for readmission was constructed, and its predictive performance was evaluated. Results A total of 483 neonates with hyperbilirubinemia due to ABO-HDN were included. The readmission rate was 13.0% (63 cases). Multivariate logistic regression analysis revealed that earlier age at phototherapy initiation, longer duration of phototherapy, occurrence of rebound hyperbilirubinemia, and higher levels of serum total bilirubin and indirect bilirubin at discharge were independent risk factors for hyperbilirubinemia readmission in ABO-HDN neonates (OR=2.373, 4.840, 6.475, 5.033, 1.336 respectively; P<0.05). A risk prediction model for ABO-HDN hyperbilirubinemia readmission was constructed based on these 5 risk factors. Model evaluation demonstrated good predictive performance. Conclusions Age at phototherapy initiation, duration of phototherapy, occurrence of rebound hyperbilirubinemia, and serum total bilirubin and indirect bilirubin levels at discharge are significant influencing factors for readmission due to hyperbilirubinemia in neonates with ABO-HDN. Close monitoring during discharge planning and follow-up management for such neonates is crucial to reduce readmission rates.

In recent years, the incidence rate of pertussis in China has been steadily increasing, presenting an increasingly severe challenge for disease prevention and control. To strengthen the immune barrier in the population and effectively curb the spread of pertussis, National Disease Control and Prevention Administration of China and other relevant authorities optimized the immunization procedure for diphtheria-tetanus-pertussis vaccine, with the new procedure implemented in 2025. This adjustment includes three key measures: advancing the initial dose of the vaccine from 3 months to 2 months of age, extending the interval between primary immunization doses from 1 month to 2 months, and adding an extra dose of acellular diphtheria-tetanus-pertussis vaccine at 6 years of age. This article discusses potential changes in the epidemiology and clinical manifestations of pertussis following such adjustments for immunization procedure, and awareness of these changes will facilitate the accurate identification of pertussis cases, which is crucial for evaluating the impact of these adjustments and further optimizing immunization strategies.

Objective To explore the manifestations of sensory hypersensitivity in children with autism spectrum disorder (ASD) and individuals with subclinical autistic traits. Methods From September 2021 to April 2023, interviews were conducted on 18 college students with high levels of autistic traits and sensory hypersensitivity selected using the Adolescent/Adult Sensory Profile and the Autism Spectrum Quotient (as subclinical group). Interviews were also conducted on the parents of 11 children with ASD aged 6-13 years selected using the intensity sampling method (as clinical group). Qualitative content analysis and thematic analysis were performed on the interview texts to investigate the scenarios and impact of sensory hypersensitivity and coping strategies in the two groups. Results The Autism Spectrum Quotient score was significantly positively correlated with sensory hypersensitivity (r=0.504, P<0.001; n=225). Sensory modalities that triggered sensitive reactions were similar in the subclinical and clinical groups, with auditory hypersensitivity being the most prominent. Sensory hypersensitivity had significant negative impact on emotional wellbeing, cognitive ability, physical health, interpersonal relationships, and general adaptive functioning. These dimensions were interconnected, culminating in a holistic experience. Avoidance was the most commonly used coping mechanism for both groups (16 subclinical participants mentioned it 44 times; 8 clinical participants mentioned it 40 times). The clinical group required more support and help from their caregivers (18 times), while the subclinical group used more proactive coping strategies (e.g., facing sensitive scenarios, distracting attention) to alleviate the negative impact (51 times). Conclusions Sensory hypersensitivity is a common manifestation across the broad ASD phenotype, posing negative effects on multiple aspects of their lives. There is an urgent need for social tolerance and acceptance as well as the development of effective intervention measures.

Objective To explore the clinical characteristics and prognostic factors of pediatric acute myeloid leukemia (AML) with monosomy 7 (-7) and deletion of the long arm of chromosome 7 (7q-). Methods A retrospective study was conducted on the clinical data, treatment, and prognosis of children with -7/7q- AML who were admitted to the Department of Pediatrics at Peking University People's Hospital from January 2010 to December 2024. Results A total of 869 children with AML who had complete karyotype data were included, of whom 32 (3.7%) had -7/7q- chromosomal abnormalities. There were 20 males and 12 females, and the median age at diagnosis was 6 years. Six children (19%) had isolated -7; 2 (6%) had isolated 7q-; and 24 (75%) had additional chromosomal abnormalities. After induction chemotherapy, complete remission (CR) was achieved in 16 children (50%). At the last follow-up, 15 children (47%) had died and 17 (53%) were alive. The 3-year disease-free survival (DFS) rate was (54.1±0.1)%, and the 3-year overall survival (OS) rate was (52.6±0.1)%. The multivariable analysis showed that hematopoietic stem cell transplantation (HSCT) was an independent prognostic factor for DFS (HR=0.17, 95%CI: 0.04-0.62, P=0.008) and OS (HR=0.16, 95%CI: 0.04-0.59, P=0.006), with better outcomes in children who underwent HSCT. Conclusions The incidence of -7/7q- chromosomal abnormalities in children with AML is 3.7%. Additional chromosomal aberrations are common, and the CR rate after induction chemotherapy is low. HSCT is associated with improved prognosis and survival.

Objective To identify infant sleep patterns and explore their influencing factors, providing scientific evidence for the formation and intervention of healthy sleep patterns. Methods A total of 1 483 12-month-old infants from the Shanghai Birth Cohort were included. Sleep status was assessed using the Brief Infant Sleep Questionnaire. Latent class analysis was performed to integrate sleep behavior and sleep problem variables and to identify typical sleep patterns. A binary logistic regression model was employed to examine influencing factors. Results Two sleep patterns were identified: a good sleep pattern characterized by healthier sleep habits and fewer sleep problems, and a poor sleep pattern characterized by poorer sleep habits and more sleep problems. Logistic regression analysis showed that, compared with infants who had stopped breastfeeding, infants still being breastfed at 12 months were more likely to develop poor sleep patterns (OR=1.725, P<0.001). Compared with infants from families with better economic status, those from families with economic hardship were more likely to develop poor sleep patterns (OR=1.638, P=0.003). Outdoor activity for more than one hour per day was associated with better sleep patterns (OR=0.633, P<0.001), while screen exposure increased the risk of poor sleep patterns (OR=1.887, P<0.001). Conclusions Infant sleep patterns are influenced by multiple factors; increasing outdoor activity and limiting screen exposure help infants form good sleep patterns.

Objective To investigate the disease burden of attention-deficit/hyperactivity disorder (ADHD) among children and adolescents in China and to predict future trends, in order to provide evidence for disease control strategies. Methods Based on data from the Global Burden of Disease Study 2021 (GBD 2021), joinpoint regression and prediction models were constructed to analyze and forecast the trends in ADHD burden indicators among Chinese children and adolescents from 1990 to 2021. Results In 2021, the incidence, prevalence, and disability-adjusted life years (DALYs) rates of ADHD among children and adolescents in China increased by 41.46%, 21.44%, and 21.75%, respectively, compared to 1990. From 1990 to 2021, the disease burden of ADHD showed an overall upward trend across sex and age groups, with a heavier burden among males. The highest incidence was observed in children aged 5-9 years, while the highest prevalence and DALY rates were found in those aged 10-14 years. By 2031, the incidence, prevalence, and DALY rates of ADHD among Chinese children and adolescents are projected to reach 324.88 per 100 000, 3 762.36 per 100 000, and 45.85 per 100 000, respectively. Conclusions From 1990 to 2021, the incidence, prevalence, and DALY rates of ADHD among children and adolescents in China have all increased, suggesting that more proactive prevention and intervention measures may be needed to alleviate the disease burden of ADHD in this population.

Objective To evaluate the efficacy and safety of ibuprofen in treating hemodynamically significant patent ductus arteriosus (hsPDA) in preterm infants of different postnatal ages at treatment initiation. Methods Clinical records of infants with gestational age <37 weeks who received ibuprofen for hsPDA in the Department of Neonatology, Fourth Hospital of Shijiazhuang, from January 2020 to December 2023 were retrospectively reviewed. One hundred eligible infants were divided by the postnatal age at the first ibuprofen administration into three groups: group A (≤4 days), group B (5-7 days), and group C (>7 days). Clinical efficacy and safety indicators were compared among groups. Results After treatment, cure rates were 92% in group A, 72% in group B, and 60% in group C, and effective rates were 8%, 25%, and 33%, respectively. Differences in clinical efficacy among the three groups were statistically significant (P<0.05). No significant differences were observed among groups in the incidence of pulmonary hemorrhage, gastrointestinal bleeding, cholestasis, bronchopulmonary dysplasia, necrotizing enterocolitis, intracranial hemorrhage, or acute kidney injury (P>0.05). Conclusions For hsPDA requiring pharmacologic therapy, earlier oral ibuprofen administration yields a higher ductal closure rate and does not increase the incidence of adverse events.

Objective To investigate the long-term neurodevelopmental outcomes of neonates with different types of stroke. Methods Data from 41 neonates diagnosed with stroke at the Third Affiliated Hospital of Zhengzhou University between January 2017 and May 2024 were retrospectively reviewed. Stroke types included arterial ischemic stroke (AIS), hemorrhagic stroke (HS), and cerebral sinovenous thrombosis (CSVT). All infants were followed to 2 years of age. Neurodevelopmental outcomes were assessed using the Bayley Scales of Infant and Toddler Development, Third Edition (BSID-III), focusing on motor and cognitive development. Outcomes were compared according to vascular involvement. Results Of the 41 neonates, 35(85%) had AIS, 5(12%) had HS, and 1(2%) had CSVT. Among the 35 AIS cases, 16(46%) involved the main trunk of the middle cerebral artery (MCA). The incidences of cerebral palsy (CP) and cognitive developmental delay were significantly higher in the MCA main trunk group than in the non-main-trunk group (P<0.05). Among the 5 HS cases, 1 involving the frontal cortical branch of the MCA died at 12 days of life. Two cases involving the temporal cortical branches had BSID-III cognitive development indices of 102 and 106, and motor development indices of 90 and 95 at 2 years. The remaining 2 cases involving the MCA main trunk developed CP. The single CSVT case involved the great cerebral vein and presented with CP and language developmental impairment. Conclusions AIS is the most common type of neonatal stroke and shows poorer outcomes by 2 years of age. Early identification and early intervention are essential in clinical practice.
