Effect of somatostatin on gastrointestinal hormone levels and clinical outcomes in critically ill infants after gastrointestinal surgery: a prospective randomized controlled study
Objective To explore the effects of somatostatin on the levels of gastrointestinal hormones and clinical outcomes in critically ill infants after gastrointestinal surgery. Methods Using a random number table method, critically ill infants after gastrointestinal surgery who were admitted to the Intensive Care Unit of Xuzhou Children's Hospital from June 2019 to June 2021 were randomly divided into an observation group (29 cases) and a control group (30 cases). The control group received routine treatment such as anti-infection and hemostasis after surgery, while the observation group received somatostatin in addition to the routine treatment [3.5 μg/(kg·h) infusion for 7 days]. The levels of serum gastrin (GAS), motilin (MTL), insulin, and glucagon-like peptide-1 (GLP-1) before surgery, on the 3rd day after surgery, and on the 7th day after surgery were compared between the two groups. The recovery progress and incidence of complications after surgery were also compared between the two groups. Results There was no significant difference in the levels of serum GAS, MTL, insulin, and GLP-1 between the two groups before surgery (P>0.05). On the 3rd and 7th day after surgery, the levels of serum GAS, MTL, insulin, and GLP-1 in the observation group were higher than those in the control group (P<0.05). In the observation group, the levels of GAS, MTL, insulin, and GLP-1 on the 7th day after surgery were higher than those before surgery and on the 3rd day after surgery (P<0.05), and the levels on the 3rd day after surgery were higher than those before surgery (P<0.05). There was no significant difference in the levels of serum GAS, MTL, and insulin before surgery, on the 3rd day after surgery, and on the 7th day after surgery in the control group (P>0.05). The level of GLP-1 on the 7th day after surgery was higher than that before surgery and on the 3rd day after surgery (P<0.05), and the level on the 3rd day after surgery was higher than that before surgery (P<0.05) in the control group. The observation group had shorter first time of anal exhaust, recovery time of bowel sounds, and first time of defecation after surgery compared to the control group (P<0.05). The incidence of complications after surgery in the observation group was lower than that in the control group (10% vs 33%, P<0.05). Conclusions Somatostatin can increase the levels of serum GAS, MTL, insulin, and GLP-1 in critically ill infants after gastrointestinal surgery, promote the recovery of gastrointestinal function, and reduce the incidence of postoperative complications.

Risk factors and prognosis of hypotension within 72 hours after birth in extremely preterm infants
Objective To investigate the risk factors and prognosis of hypotension within 72 hours after birth in extremely preterm infants. Methods A retrospective analysis was conducted on clinical data of extremely preterm infants admitted to the Children's Hospital of Zhejiang University School of Medicine from January 2019 to April 2022. Based on the presence of hypotension within 72 hours after birth, the eligible infants were divided into a hypotension group (41 cases) and a normotension group (82 cases). The clinical characteristics, echocardiographic parameters within 72 hours after birth, and early complications were compared between the two groups. Multivariate logistic regression analysis was used to explore the risk factors for hypotension within 72 hours after birth, and receiver operating characteristic curve analysis was performed to evaluate the predictive value of relevant indicators for the occurrence of hypotension within 72 hours after birth in the preterm infants. Results The proportion of infants who required medication or surgical closure of patent ductus arteriosus (PDA), the proportions of infants with intraventricular hemorrhage ≥ grade III and severe pulmonary hemorrhage, and the mortality rate within 7 days in the hypotension group were significantly higher than those in the normotension group (P<0.05). Multivariate logistic regression analysis showed that lower birth weight, larger PDA diameter, and hemodynamically significant PDA were risk factors for the occurrence of hypotension within 72 hours after birth in extremely preterm infants (P<0.05). The receiver operating characteristic curve analysis showed that the combination of birth weight, PDA diameter, and hemodynamically significant PDA had an area under the curve of 0.873 (95%CI: 0.802-0.944, P<0.05) for predicting hypotension within 72 hours after birth, with a sensitivity of 73.2% and specificity of 91.5%. Conclusions Hypotension within 72 hours after birth is closely related to birth weight and PDA, and increases the risk of early severe complications and mortality in extremely preterm infants.

Global disease burden of neonatal jaundice from 1990 to 2019
Objective To examine the global, regional, and national disease burden of neonatal jaundice. Methods The 2019 Global Burden of Disease database was searched to collect incident cases/incidence and deaths/mortality of neonatal jaundice, as well as global socio-demographic index (SDI) and universal health coverage index (UHCI). The epidemiological trend of neonatal jaundice from 1990 to 2019 was analyzed. The correlations between incidence/mortality of neonatal jaundice and SDI and UHCI were evaluated. Results From 601 681 in 1990 to 626 005 in 2019, with a 4.04% increase in global incident cases of neonatal jaundice. The overall age-standardized incidence rate exhibited an increase [estimated annual percent change=0.13 (95%CI: 0.03 to 0.23)] during this period. Additionally, deaths due to neonatal jaundice decreased by 58.83%, from 128 119 in 1990 to 52 742 in 2019. The overall age-standardized mortality rate showed a decrease [estimated annual percent change=-2.78 (95%CI: -3.00 to -2.57)] over the same period. Countries with lower SDI, such as India, Pakistan, and Nigeria, reported a higher proportion of neonatal morbidity and mortality. In 2019, a negative correlation was observed between estimated annual percent change in age-standardized mortality rate and SDI (ρ=-0.320, P<0.05) or UHCI (ρ=-0.252, P<0.05). Conclusions The global incidence of neonatal jaundice is on the rise, while the mortality rate is declining. The burden of neonatal jaundice is influenced by social development, economic factors, and the level of medical care.

Characteristics of the left heart structure and function in 86 term neonates with intrauterine growth restriction
Objective To study the left heart structure and functional characteristics of term neonates with intrauterine growth restriction (IUGR). Methods This study included 86 term neonates with IUGR admitted to the Neonatal Ward of Beijing Friendship Hospital, Capital Medical University from January 2019 to January 2022 as the IUGR group, as well as randomly selected 86 term neonates without IUGR born during the same period as the non-IUGR group. The clinical data and echocardiographic data were compared between the two groups. Results The analysis of left heart structure and function showed that compared with the non-IUGR group, the IUGR group had significantly lower left ventricular mass, left ventricular end-diastolic diameter, left ventricular end-systolic diameter, left atrial diameter, end-diastolic interventricular septal thickness, left ventricular posterior wall thickness, left ventricular end-diastolic volume, left ventricular end-systolic volume, and stroke volume (P<0.05) and significantly higher ratio of end-diastolic interventricular septal thickness to left ventricular posterior wall thickness, proportion of neonates with a mitral peak E/A ratio of ≥1, and cardiac index (P<0.05). The Spearman correlation analysis suggested that stroke volume was positively correlated with birth weight and body surface area (rs=0.241 and 0.241 respectively; P<0.05) and that the ratio of end-diastolic interventricular septal thickness to left ventricular posterior wall thickness was negatively correlated with birth weight and body surface area (rs=-0.229 and -0.225 respectively; P<0.05). Conclusions The left ventricular systolic function of neonates with IUGR is not significantly different from that of neonates without IUGR. However, the ventricular septum is thicker in neonates with IUGR. This change is negatively correlated with birth weight and body surface area. The left ventricular diastolic function may be impaired in neonates with IUGR.

Association between HLA-DRB1 gene polymorphisms and genetic susceptibility of early-onset severe preeclampsia
Objective To explore the correlation between the single nucleotide polymorphisms (SNP) of rs3135388, rs114293611 and rs142804168 of HLA-DRB1 gene and early-onset severe preeclampsia (sPE). Methods Blood samples were collected from 102 early-onset sPE mothers and their neonates (sPE group), as well as 120 normotensive mothers and their neonates (control group). Sanger sequencing was performed to compare the genotype distribution, allele frequencies, and differences in genotype distribution after maternal-infant compatibility between the two groups. Results Statistically significant differences in genotype distribution at rs114293611 of HLA-DRB1 gene were observed between sPE and control groups in both mothers and neonates (P<0.05). The frequency of the T allele at rs114293611 was higher in the sPE group of neonates than that in the control group (P<0.05), while no significant difference was found between the two groups of mothers (P>0.05). The maternal-infant genotype compatibility analysis showed significant differences in genotype distribution between sPE and control groups (P<0.05). There were no significant differences in genotype distribution and allele frequencies at rs3135388 and rs142804168 of HLA-DRB1 gene between the two groups of mothers and neonates (P>0.05). Conclusions The SNP at rs114293611 of HLA-DRB1 gene may be associated with the development of early-onset sPE in mothers. Maternal-infant genotype compatibility abnormality at rs114293611 of HLA-DRB1 gene may be a predisposition factor for the development of sPE.

Differential diagnosis of autism spectrum disorder and global developmental delay based on machine learning and Children Neuropsychological and Behavioral Scale
Objective To investigate the efficacy and required indicators of Children Neuropsychological and Behavioral Scale-Revision 2016 (CNBS-R2016) in the differential diagnosis of autism spectrum disorder (ASD) and global developmental delay (GDD). Methods A total of 277 children with ASD and 415 children with GDD, aged 18-48 months, were enrolled as subjects. CNBS-R2016 was used to assess the developmental levels of six domains, i.e., gross motor, fine motor, adaptive ability, language, social behavior, and warning behavior, and a total of 13 indicators on intelligence age and developmental quotient (DQ) were obtained as the input features. Five commonly used machine learning classifiers were used for training to calculate the classification accuracy, sensitivity, and specificity of each classifier. Results DQ of warning behavior was selected as the first feature in all five classifiers, and the use of this indicator alone had a classification accuracy of 78.90%. When the DQ of warning behavior was used in combination with the intelligence age of warning behavior, gross motor, and language, it had the highest classification accuracy of 86.71%. Conclusions Machine learning combined with CNBS-R2016 can effectively distinguish children with ASD from those with GDD. The DQ of warning behavior plays an important role in machine learning, and its combination with other features can improve classification accuracy, providing a basis for the efficient and accurate differential diagnosis of ASD and GDD in clinical practice.

Clinical effect of different immunosuppressive treatment regimens in children with ocular myasthenia gravis: a retrospective analysis
Objective To investigate the clinical effect of different immunosuppressive treatment regimens in children with ocular myasthenia gravis (OMG). Methods A retrospective analysis was conducted on 130 children with OMG who were treated in the Department of Neurology, Jiangxi Children's Hospital, from February 2018 to February 2023. According to the treatment regimen, they were divided into four groups: glucocorticoid (GC) group (n=29), mycophenolate mofetil (MMF) group (GC+MMF; n=33), methotrexate (MTX) group (GC+MTX; n=30), and tacrolimus (FK506) group (GC+FK506; n=38). Treatment outcomes and adverse reactions were compared among the groups. Results After 3 months of treatment, the FK506 group had significantly lower scores of Myasthenia Gravis Quantitative Scale and Myasthenia Gravis-Specific Activities of Daily Living than the other three groups (P<0.05). After 3 months of treatment, the FK506 group had a significantly lower dose of prednisone than the GC group, and after 6 and 9 months of treatment, the MMF, MTX, and FK506 groups had a significantly lower dose of prednisone than the GC group (P<0.05). After 12 months of treatment, the MMF, MTX, and FK506 groups had a significantly lower incidence rate of GC-related adverse reactions than the GC group (P<0.05). Conclusions For children with OMG, the addition of various immunosuppressants can reduce the dosage of GC and adverse reactions. Among them, FK506 shows superior efficacy compared to other immunosuppressants in the early treatment of OMG.

Application of brain functional connectivity and nonlinear dynamic analysis in brain function assessment for infants with controlled infantile spasm
Objective To investigate the role of brain functional connectivity and nonlinear dynamic analysis in brain function assessment for infants with controlled infantile spasm (IS). Methods A retrospective analysis was performed on 14 children with controlled IS (IS group) who were admitted to the Department of Neurology, Anhui Provincial Children's Hospital, from January 2019 to January 2023. Twelve healthy children, matched for sex and age, were enrolled as the control group. Electroencephalogram (EEG) data were analyzed for both groups to compare the features of brain network, and nonlinear dynamic indicators were calculated, including approximate entropy, sample entropy, permutation entropy, and permutation Lempel-Ziv complexity. Results Brain functional connectivity showed that compared with the control group, the IS group had an increase in the strength of functional connectivity, and there was a significant difference between the two groups in the connection strength between the Fp2 and F8 channels (P<0.05). The network stability analysis showed that the IS group had a significantly higher network stability than the control group at different time windows (P<0.05). The nonlinear dynamic analysis showed that compared with the control group, the IS group had a significantly lower sample entropy of Fz electrode (P<0.05). Conclusions Abnormalities in brain network and sample entropy may be observed in some children with controlled IS, and it is suggested that quantitative EEG analysis parameters can serve as neurological biomarkers for evaluating brain function in children with IS.

Risk factors for hemorrhagic cystitis in children with β-thalassemia major after allogeneic hematopoietic stem cell transplantation
Objective To explore the risk factors for hemorrhagic cystitis (HC) in children with β-thalassemia major (TM) undergoing allogeneic hematopoietic stem cell transplantation (allo-HSCT). Methods A retrospective analysis was conducted on clinical data of 247 children with TM who underwent allo-HSCT at Shenzhen Children's Hospital from January 2021 to November 2022. The children were divided into an HC group (91 cases) and a non-HC group (156 cases) based on whether HC occurred after operation. Multivariable logistic regression analysis was used to explore the risk factors for HC, and the receiver operating characteristic curve was used to analyze the predictive efficacy of related factors for HC. Results Among the 247 TM patients who underwent allo-HSCT, the incidence of HC was 36.8% (91/247). Univariate analysis showed age, incompatible blood types between donors and recipients, occurrence of acute graft-versus-host disease (aGVHD), positive urine BK virus deoxyribonucleic acid (BKV-DNA), and ≥2 viral infections were associated with the development of HC after allo-HSCT (P<0.05). Multivariable analysis revealed that incompatible blood types between donors and recipients (OR=3.171, 95%CI: 1.538-6.539), occurrence of aGVHD (OR=2.581, 95%CI: 1.125-5.918), and positive urine BKV-DNA (OR=21.878, 95%CI: 9.633-49.687) were independent risk factors for HC in children with TM who underwent allo-HSCT. The receiver operating characteristic curve analysis showed that positive urine BKV-DNA alone or in combination with two other risk factors (occurrence of aGVHD, incompatible blood types between donors and recipients) had a certain accuracy in predicting the development of HC after allo-HSCT (area under the curve >0.8, P<0.05). Conclusions Incompatible blood types between donors and recipients, occurrence of aGVHD, and positive urine BKV-DNA are risk factors for HC after allo-HSCT in children with TM. Regular monitoring of urine BKV-DNA has a positive significance for early diagnosis and treatment of HC.

Construction of a predictive model for performing bronchoalveolar lavage in children with Mycoplasma pneumoniae pneumonia and pulmonary consolidation
Objective To investigate the risk factors for performing bronchoalveolar lavage (BAL) in children with Mycoplasma pneumoniae pneumonia (MPP) and pulmonary consolidation, and to construct a predictive model for performing BAL in these children. Methods A retrospective analysis was performed for the clinical data of 202 children with MPP who were hospitalized in the Department of Pediatrics, Changzhou No. 2 People's Hospital Affiliated to Nanjing Medical University, from August 2019 to September 2022. According to whether BAL was performed, they were divided into BAL group with 100 children and non-BAL group with 102 children. A multivariate logistic regression analysis was used to identify the risk factors for performing BAL in MPP children with pulmonary consolidation. Rstudio software (R4.2.3) was used to establish a predictive model for performing BAL, and the receiver operator characteristic (ROC) curve, C-index, and calibration curve were used to assess the predictive performance of the model. Results The multivariate logistic regression analysis demonstrated that the fever duration, C-reactive protein levels, D-dimer levels, and presence of pleural effusion were risk factors for performing BAL in MPP children with pulmonary consolidation (P<0.05). A nomogram predictive model was established based on the results of the multivariate logistic regression analysis. In the training set, this model had an area under the ROC curve of 0.915 (95%CI: 0.827-0.938), with a sensitivity of 0.826 and a specificity of 0.875, while in the validation set, it had an area under the ROC curve of 0.983 (95%CI: 0.912-0.996), with a sensitivity of 0.879 and a specificity of 1.000. The Bootstrap-corrected C-index was 0.952 (95%CI: 0.901-0.986), and the calibration curve demonstrated good consistency between the predicted probability of the model and the actual probability of occurrence. Conclusions The predictive model established in this study can be used to assess the likelihood of performing BAL in MPP children with pulmonary consolidation, based on factors such as fever duration, C-reactive protein levels, D-dimer levels, and the presence of pleural effusion. Additionally, the model demonstrates good predictive performance.

Dose-response relationship between age and Streptococcus pneumoniae vaccination coverage in kindergarten children
Objective To investigate the potential relationship between age and Streptococcus pneumoniae vaccination coverage in kindergarten children, and to provide a basis for guiding vaccination and developing new protein vaccines. Methods The stratified cluster random sampling method was used to select 1 830 healthy children from six kindergartens in Shunde District, Foshan City, China, and nasopharyngeal swabs were collected for the isolation and identification of Streptococcus pneumoniae. The logistic regression model based on restricted cubic spline was used to analyze the dose-response relationship between age and Streptococcus pneumoniae vaccination coverage. Results The rate of nasal Streptococcus pneumoniae carriage was 22.46% (411/1 830) among the kindergarten children, with the predominant serotypes of 6B, 19F, 15A, 23A, 34, and 23F. The coverage rates of 10-valent pneumococcal conjugate vaccine (PCV10) and 13-valent pneumococcal conjugate vaccine (PCV13) were 53.0% and 57.9%, respectively, and there was a significant non-linear dose-response relationship between age and the coverage rates of PCV10 and PCV13 (P<0.05), with a higher coverage rate of PCV10 (88.0%) and PCV13 (91.1%) in the children aged 2 years. There was a significant non-linear dose-response relationship between age and the coverage rates of pilus islet 1 (PI-1) and pilus islet 2 (PI-2) (P<0.05), with a lower vaccination coverage rate for PI-1 (37.7%) and PI-2 (16.1%). The coverage rates of PI-1 (13.0%-58.5%) and PI-2 (6.0%-29.4%) were lower in all age groups. The virulence genes lytA (99.5%) and ply (99.0%) associated with candidate protein vaccines showed higher vaccination coverage rates. Conclusions There is a significant non-linear dose-response relationship between the age of kindergarten children and the coverage rates of PCV10 and PCV13 serotypes, and kindergarten children aged 2 years have a relatively high coverage rate of PCV. The high prevalence of the virulence genes lytA and ply shows that they are expected to become candidate virulence factors for the development of a new generation of recombinant protein vaccines.

Recent research on the relationship between pulmonary microbiome and asthma endotypes in children
Bronchial asthma is not considered a singular disease, but rather a collection of syndromes with multiple phenotypes and mechanisms that involve various signaling pathways. It typically emerges during the preschool years, and its etiology is intricate and diverse. In recent years, the advancement of high-throughput sequencing technology has revealed that early alterations in lung microbiota may be associated with asthma incidence and progression. Moreover, significant variations in lung microbiota have been observed among different airway inflammation profiles, known as asthma endotypes. Hence, a comprehensive understanding of the characteristics of lung microbiota in children with asthma can aid in managing disease progression and improving long-term prognosis. Additionally, such insights may spark novel approaches to diagnosing and treating childhood asthma.

The male patient was referred to the hospital at 44 days old due to dyspnea after birth and inability to wean off oxygen. His brother died three days after birth due to respiratory failure. The main symptoms observed were respiratory failure, dyspnea, and hypoxemia. A chest CT scan revealed characteristic reduced opacity in both lungs with a "crazy-paving" appearance. The bronchoalveolar lavage fluid (BALF) showed periodic acid-Schiff positive proteinaceous deposits. Genetic testing indicated a compound heterozygous mutation in the ABCA3 gene. The diagnosis for the infant was congenital pulmonary alveolar proteinosis (PAP). Congenital PAP is a significant cause of challenging-to-treat respiratory failure in full-term infants. Therefore, congenital PAP should be considered in infants experiencing persistently difficult-to-treat dyspnea shortly after birth. Early utilization of chest CT scans, BALF pathological examination, and genetic testing may aid in early diagnosis.
