Short-term persistent symptoms in preschool children with mild/common coronavirus disease 2019 caused by Omicron variant infection after discharge: a follow-up study
Objective To investigate the persistent symptoms in preschool children after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron variant infection, and to provide a basis for developing follow-up plans after infection and reducing and preventing related symptoms after infection. Methods The children, aged 0-5 years, who had Omicron BA.2 infection and were discharged from the pediatric ward of Shanghai Renji Hospital South Branch from April 13 to May 8, 2022, were enrolled as subjects, and related demographic and clinical data were collected. The children were followed up from the time to SARS-CoV-2 clearance for two consecutive tests with an interval of >24 hours till 4-5 weeks after clearance, and telephone follow-up was performed on the primary caregivers to investigate related persistent symptoms. Results Among the 103 children who met the inclusion criteria, there were 61 boys and 42 girls, with a median age of 18 months. The primary caregivers who had received two or more doses of COVID-19 vaccine accounted for 64.1% (66/103). Fever (98.1%, 101/103) was the most common symptom in these children, followed by cough/expectoration (63.1%, 65/103), gastrointestinal problems (37.9%, 39/103), loss of appetite (30.1%, 31/103), weakness (27.2%, 28/103), and nasal obstruction/runny nose (16.5%, 17/103). The follow-up at 1 month after discharge reported that 44 children (42.7%) had at least one persistent symptom, including respiratory symptoms in 14 children (13.6%) and gastrointestinal problems in 19 children (18.4%). The children whose primary caregivers received two or more doses of COVID-19 vaccine had a significantly shorter time to SARS-CoV-2 clearance than those whose primary caregivers did not receive or only received one dose of COVID-19 vaccine (P<0.05), while there was no significant difference between the two groups in the proportion of children with at least one persistent symptom (P>0.05). Conclusions Nearly half of the preschool children may have related persistent symptoms after SARS-CoV-2 Omicron variant infection, mainly gastrointestinal and respiratory symptoms. Most of the symptoms may be mild, and continuous follow-up is needed to observe their outcomes. Vaccination of COVID-19 vaccine for primary caregivers has a certain protective effect on children.

Features of unintentional injury in children under the impact of coronavirus disease 2019
Objective To study the features of unintentional injury in children under the impact of coronavirus disease 2019 (COVID-19). Methods A retrospective analysis was performed on the medical data of 2 526 children with unintentional injury in Xinhua Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from July 2019 to June 2022. The study period was divided into 5 stages: before the epidemic (July to December, 2019), the Wuhan epidemic period (January to April, 2020), the epidemic remission period in China (May 2020 to February 2022), the Shanghai epidemic period (March to May, 2022), and the epidemic remission period in Shanghai (June 2022). The incidences of unintentional injury in children at different time stages and different ages were compared. A questionnaire survey was conducted on 107 children of the 2 526 children to explore the features of unintentional injury. Results There were significant differences in gender composition, age, age distribution and proportion of many types of unintentional injuries among the five time stages (P<0.05). There was a reduction in the number of children who attended the emergency department due to unintentional injury during the Wuhan epidemic and the Shanghai epidemic. The proportion of children with trauma-related unintentional injuries in each stage reached more than 50%, and the proportion of children with trauma-related unintentional injuries reached 63.9% and 82.0%, respectively during the Wuhan epidemic and the Shanghai epidemic. Most children suffering from unintentional injury were mainly school-aged and preschool children (1 823 children, 72.17%). Compared with the same period of Shanghai epidemic in 2021, the age of children with unintentional injury was younger (median 7 years vs 11 years), and the proportion of children with trauma-related unintentional injuries increased (97% vs 69%) during the Shanghai epidemic (P<0.05). Conclusions Under the COVID-19 epidemic, there is a reduction in the number of children with unintentional injury, while there is an increase in the proportion of children with trauma-related unintentional injuries. Unintentional injury is more common among school-aged and preschool children.

Clinical features of children with coronavirus disease 2019 complicated by acute encephalitis and related research advances
Coronavirus disease 2019 (COVID-19) has become a worldwide pandemic since the end of 2019. There is an increasing number of reports on nervous system symptoms, among which encephalitis is considered a serious neurological complication of COVID-19, but there are few reports of this complication in China. Acute encephalitis has severe symptoms. If it is not identified early and treated in time, the mortality is high and the prognosis is poor. During the current global epidemic, it is necessary to pay attention to the severe nervous system symptoms of COVID-19. Therefore, this article summarizes the clinical features of COVID-19 complicated by acute encephalitis through literature review and a detailed analysis of medical records, so as to provide a reference for clinicians to deal with the cases of COVID-19 complicated by acute encephalitis.

Efficacy of volume-targeted ventilation versus high-frequency oscillatory ventilation in the treatment of neonatal respiratory distress syndrome
Objective To study the clinical efficacy of volume-targeted ventilation (VTV) versus high-frequency oscillatory ventilation (HFOV) in the treatment of neonatal respiratory distress syndrome (NRDS). Methods A retrospective cohort analysis was performed on the medical data of 140 neonates with severe NRDS who were admitted from September 2016 to February 2022, with 55 neonates in the VTV group and 85 in the HFOV group. The neonates in the VTV group received conventional mechanical ventilation and target tidal volume, and those in the HFOV group received HFOV. Arterial blood gas parameters were collected at 48 hours after admission, and related indices during hospitalization were recorded, including mortality rate, duration of invasive mechanical ventilation, duration of oxygen therapy, and the incidence rates of complications. Results Compared with the VTV group, the HFOV group had significantly lower incidence rates of grade Ⅲ-Ⅳ periventricular-intraventricular hemorrhage and neonatal necrotizing enterocolitis (P<0.05), and there were no significant differences between the two groups in the duration of invasive mechanical ventilation, the duration of oxygen therapy, mortality rate, and the incidence rates of bronchopulmonary dysplasia, hypocapnia, hypercapnia, periventricular leukomalacia, and retinopathy of prematurity (P>0.05). Conclusions HFOV has a better clinical efficacy than VTV in the treatment of NRDS.

Influencing factors for the development and severity of bronchopulmonary dysplasia in preterm infants with a gestational age of <32 weeks and a birth weight of <1 500 g
Objective To study the influencing factors for the development and severity of bronchopulmonary dysplasia (BPD) in preterm infants with a gestational age of <32 weeks and a birth weight of <1 500 g. Methods A retrospective analysis was performed on the medical data of preterm infants with a gestational age of <32 weeks and a birth weight of <1 500 g who were admitted to Women and Children's Hospital Affiliated to Xiamen University from January 1, 2017 to December 31, 2021. According to oxygen dependence on day 28 after birth, they were divided into two groups: BPD (n=218) and non-BPD (n=142). According to disease severity based on oxygen concentration required at the corrected age of 36 weeks or at discharge, the infants with BPD were divided into two groups: mild BPD (n=154) and moderate/severe BPD (n=64). Indices such as perinatal data and nutritional status were compared between groups. The multivariate logistic regression analysis was used to determine the influencing factors for BPD and its severity. Results The incidence rate and severity of BPD increased with the reduction in gestational age and birth weight (P<0.05). The multivariate logistic regression analysis showed that a long duration of invasive mechanical ventilation (OR=1.320, P<0.05), hemodynamically significant patent ductus arteriosus (OR=2.032, P<0.05), and a prolonged time to reach oral calorie goal of 110 kcal/(kg·d) (OR=1.041, P<0.05) were risk factors for BPD, while an older gestational age was a protective factor against BPD (OR=0.535, P<0.05). Early-onset sepsis (OR=2.524, P<0.05) and a prolonged time to reach oral calorie goal of 110 kcal/(kg·d) (OR=1.029, P<0.05) were risk factors for moderate/severe BPD, while a high mean weight growth velocity was a protective factor against moderate/severe BPD (OR=0.906, P<0.05). Conclusions The incidence rate and severity of BPD in preterm infants with a gestational age of <32 weeks and a birth weight of <1 500 g can be reduced by shortening the duration of invasive mechanical ventilation, giving early treatment of early-onset sepsis and hemodynamically significant patent ductus arteriosus, adopting active enteral nutritional strategies, and increasing mean weight growth velocity.

Serum free fatty acid level in children with primary hypertension Hot!
Objective To examine the serum level of free fatty acid (FFA) in children with primary hypertension and its value in the pathogenesis, prevention, and treatment of primary hypertension in children. Methods In this retrospective study, 34 children with primary hypertension who were treated for the first time in Children's Hospital Affiliated to Capital Institute of Pediatrics from January to June, 2021, were enrolled as the hypertension group, and 32 children with normal blood pressure who underwent physical examination during the same period were enrolled as the control group. The two groups were compared in terms of the levels of fasting serum FFA, fasting serum triglyceride (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and non-high-density lipoprotein cholesterol (non-HDL-C). The multivariate logistic regression model was used to analyze the influence of FFA on the development of primary hypertension. Results Compared with the control group, the hypertension group had significantly higher body mass index (BMI), systolic blood pressure, and diastolic blood pressure (P<0.05), as well as significantly higher serum levels of FFA, TG, LDL-C, and non-HDL-C and a significantly lower serum level of HDL-C (P<0.05). Compared with the control group, the hypertension group had significantly higher rates of elevated serum FFA (>0.45 mmol/L for girls and >0.60 mmol/L for boys) (P<0.05) and abnormal blood lipid levels (abnormality in at least one index among serum TG, TC, LDL-C, HDL-C, and non-HDL-C) (P<0.05). A multivariate logistic regression equation was established based on age, sex, BMI, elevated serum FFA, and abnormal blood lipid levels, and the results showed that elevated serum FFA was an independent risk factor for primary hypertension in children (OR=17.560, 95%CI: 1.964-157.003, P<0.05). Conclusions There is a significant increase in serum FFA level in children with primary hypertension, and the increase in serum FFA can increase the risk of primary hypertension in children.

Clinical and gastroscopic features of children with cyclic vomiting syndrome: an analysis of 63 cases
Objective To study the clinical and gastroscopic features of children with cyclic vomiting syndrome. Methods A retrospective analysis was performed on the medical data of 63 children with cyclic vomiting syndrome who were hospitalized and followed up in Beijing Tsinghua Changgung Hospital, School of Clinical Medicine, Tsinghua University from August 2019 to March 2022. Results Among the 63 children, there were 30 boys and 33 girls, with a mean age of 6.11 years, a mean course of disease of 2.57 years, and a mean vomiting period of 4.04 days. The most common accompanying symptom was listlessness or somnolence (55/63, 87%), followed by anorexia (45/63, 71%), abdominal pain or abdominal discomfort (40/63, 63%), constipation (19/63, 30%), salivation (12/63, 19%), nausea (11/63, 17%), headache (11/63, 17%), fever (6/63, 10%), and rash (1/63, 2%). All 63 children underwent gastroscopy, among whom 3 had no marked abnormalities, 22 (35%) had chronic superficial gastritis or chronic non-atrophic gastritis alone, and 38 (60%) had other abnormal changes aside from chronic gastritis (16 children with reflux esophagitis, 12 with bile reflux gastritis, 13 with duodenitis, 10 with erosive gastritis, and 5 with gastric or duodenal ulcer). Among the 63 children, 42 underwent pathological examinations of gastric mucosa, among whom 5 had no marked abnormalities, 34 had mild chronic gastritis, 2 had moderate chronic gastritis, and 1 had severe chronic gastritis. Among the 63 children, 15 received 24-hour dynamic esophageal pH monitoring during the interictal period, among whom 9 children were found to have pathological acid reflux. Conclusions In addition to recurrent vomiting, most children with cyclic vomiting syndrome also have the symptoms such as somnolence or listlessness, anorexia, and abdominal pain. The main manifestation on gastroscopy is chronic gastritis, and most children may also have reflux esophagitis, bile reflux gastritis, and erosive gastritis. Mild chronic gastritis is the main pathological change of gastric mucosa.

Establishment of a nomogram model for the early diagnosis of childhood sepsis
Objective To establish a nomogram model for the early diagnosis of sepsis in children. Methods A total of 76 children with sepsis who were admitted to Sichuan Maternal and Child Health Hospital from January 2018 to June 2021 were retrospectively selected as the sepsis group. After matching for sex and age (±2 years) at a ratio of 1:1:1, 76 children with local infection who were hospitalized during the same period were enrolled as the local infection group, and 76 children with non-infectious diseases were enrolled as the control group. The three groups were compared in terms of laboratory markers and the results of quick Sequential Organ Failure Assessment (qSOFA) and Pediatric Critical Illness Score (PCIS). A multivariate logistic regression analysis was used to investigate the association between the above indicators and sepsis. R4.1.3 software was used to establish and validate the nomogram model for the early diagnosis of sepsis based on the results of the multivariate analysis. A receiver operating characteristic (ROC) curve analysis was used to evaluate the value of the nomogram model, and the Bootstrap method was used to perform the internal validation of the model. Results The multivariate logistic regression analysis showed that soluble triggering receptor expressed on myeloid cells-1, qSOFA score, PCIS score, C-reactive protein, interleukin-6, and interleukin-10 were independently associated with childhood sepsis (P<0.05). The above indicators were used to establish a nomogram for the early diagnosis of sepsis, with an area under the ROC curve of 0.837 (95%CI: 0.760-0.914), and the calibration curve results showed a mean absolute error of 0.024, suggesting that the performance of this model was basically consistent with that of the ideal model. Conclusions The indicators soluble triggering receptor expressed on myeloid cells-1, qSOFA score, PCIS score, C-reactive protein, interleukin-6, and interleukin-10 are independently associated with childhood sepsis, and the nomogram model established based on these indicators has high discriminatory ability and accuracy in the early diagnosis of sepsis in children.

Association of Haemophilus influenzae infection with environmental and climatic factors in Suzhou, China
Objective To investigate the epidemiological characteristics of respiratory Haemophilus influenzae (HI) infection in children in Suzhou, China and its association with climatic factors and air pollutants. Methods The data on air pollutants and climatic factors in Suzhou from January 2016 to December 2019 were collected. Respiratory secretions were collected from 7 940 children with acute respiratory infection who were hospitalized during this period, and bacterial culture results were analyzed for the detection of HI. A stepwise regression analysis was used to investigate the association of HI detection rate with air pollutants (PM2.5, PM10, NO2, SO2, CO, and O3) and climatic factors (monthly mean temperature, monthly mean humidity, monthly total rainfall, monthly total sunshine duration, and monthly mean wind speed). Results In 2016-2019, the 4-year overall detection rate of HI was 9.26% (735/7 940) among the children in Suzhou. The children aged <1 year and 1-<3 years had a significantly higher HI detection rate than those aged ≥3 years (P<0.01). The detection rate of HI in spring was significantly higher than that in the other three seasons, and the detection rate of HI in autumn was significantly lower than that in the other three seasons (P<0.001). The multiple linear regression analysis showed that PM10 and monthly mean wind speed were independent risk factors for the detection rate of HI: the detection rate of HI was increased by 0.86% for every 10 μg/m3 increase in the concentration of PM10 and was increased by 5.64% for every 1 m/s increase in monthly mean wind speed. Air pollutants and climatic factors had a lag effect on the detection rate of HI. Conclusions HI is an important pathogen for acute respiratory infection in children in Suzhou and is prevalent in spring. PM10 and monthly mean wind speed are independent risk factors for the detection rate of HI.

Diversity and functional prediction of gut microbiota in children with autism spectrum disorder
Objective To study the structure and diversity of gut microbiota in children with autism spectrum disorder (ASD), and to predict the metabolic function of gut microbiota. Methods Fecal samples were collected from 30 ASD children (ASD group) and 20 typically developing (TD) children (TD group). Genomic DNA was extracted, the 16S rDNA V4 region was amplified by PCR, and Illumina NovaSeq6000 platform was used for high-throughput sequencing. The composition and distribution characteristics of gut microbiota were analyzed for the two groups, and the metabolic function of gut microbiota was predicted. Results There were no significant differences in alpha diversity indices (Chao1, Shannon, and Simpson) of gut microbiota between the ASD and TD groups (P>0.05). At the phylum and class levels, there was no significant difference in the structure of gut microbiota between the two groups (P>0.05). Compared with the TD group, the ASD group had significantly higher abundance of Megamonas, Barnesiella, Dialister, Megasphaera, Ruminococcus_torques_group, and Fusobacterium at the genus level (P<0.05). Functional prediction analysis showed that compared with the TD group, the ASD group had a significantly lower abundance of the gut microbiota with the metabolic functions such as tryptophan degradation, glutamate degradation, and butyrate production (P<0.05) and a significantly higher abundance of the gut microbiota with the metabolic function of GABA degradation (P<0.05). Conclusions There is no significant difference in the alpha diversity of gut microbiota between ASD children and TD children, while there are differences in the composition of species at the genus level and the metabolic functions of gut microbiota.

Influence of sleep quality on symptoms in children with attention deficit hyperactivity disorder: the mediating role of working memory
Objective To study the mediating role of working memory between sleep quality and symptoms in children with attention deficit hyperactivity disorder (ADHD). Methods The cluster random sampling method was used to select 110 ADHD children and 124 normal children as subjects from grade 3-5 students in two primary schools in Kashgar, Xinjiang Uygur Autonomous Region, China. SNAP-IV, Pittsburgh Sleep Quality Index (PSQI), and visual-spatial working memory paradigm were used for investigation and comparison. Results Compared with the normal group, the ADHD group had a significantly higher total score of PSQI and scores of subjective sleep quality, sleep latency, sleep efficiency, sleep disturbance, and a higher incidence of sleep quality problems (P<0.001). The working memory score in the ADHD group was significantly lower than that in the normal group (P<0.001). In the ADHD group, the working memory score was negatively correlated with the total score of PSQI (rs=-0.271, P<0.001) and the score of symptoms (rs=-0.439, P<0.001), and the total score of PSQI was positively correlated with the score of symptoms (rs=0.540, P<0.001). Working memory had a partial mediating effect in the influence of sleep quality on symptoms in children with ADHD, accounting for 18.10% of the total effect. Conclusions Sleep quality issues are observed in some children with ADHD, and working memory plays a mediating role between sleep quality and symptoms in ADHD children.

Demographic features and compliance of children with allergic diseases receiving sublingual immunotherapy
Objective To study the demographic features of children with allergic diseases receiving standardized sublingual immunotherapy (SLIT) and the influencing factors for the compliance with SLIT. Methods A retrospective analysis was performed on the demographic features and follow-up data of 1 789 children with allergic diseases who received SLIT in Children's Hospital of Jiangxi Province from January 1, 2018 to December 31, 2020. The compliance with SLIT and its influencing factors were analyzed. Results A total of 1 789 children received SLIT, among whom there were 1 271 boys (71.05%) and 518 girls (28.95%), with an age range of 4-14 years. Among these children, 777 (43.43%) had complete compliance with SLIT and 1 012 (56.57%) withdrew from the treatment within one year. Among the 1 012 children, 354 (34.98%) withdrew from the treatment due to self-conscious inconvenient use, 346 (34.19%) withdrew due to unsatisfactory treatment outcome, 253 (25.00%) stopped the treatment due to the improvement in symptoms, and 59 (5.83%) terminated the treatment due to adverse reactions. Withdrawal was mainly observed within 1-4 months after treatment (74.31%, 752/1 012). Girls tended to have a lower compliance rate than boys, and the children with a single disease had a lower compliance rate than those with multiple diseases (P<0.05). The multivariate analysis showed that compared with boys, girls had an increased risk of withdrawal (OR=0.811, 95%CI: 0.658-0.998, P<0.05), and compared with the children with multiple diseases, the children with a single disease were more likely to withdraw from the treatment (OR=1.313, 95%CI: 1.005-1.715, P<0.05). Conclusions Children with allergic diseases tend to have poor compliance with SLIT, which is associated with sex and the number of diseases, and the main reasons for withdrawal are self-conscious inconvenient use and unsatisfactory treatment outcome.

Effect of inhibiting miR-204 expression on the learning and memory abilities of neonatal rats with intrauterine growth restriction and related mechanism
Objective To investigate the effect of inhibiting miR-204 expression on the learning and memory abilities of neonatal rats with intrauterine growth restriction (IUGR) and related mechanism. Methods A rat model of IUGR was prepared by low-protein diet. The 3-day-old IUGR rats were divided into three groups: model, miRNA antagonist control and miR-204 antagonist, with 10 rats in each group. Ten normal neonatal rats served as the control group. Morris water maze test was used to measure the learning and memory abilities of the rats. Quantitative real-time PCR was used to measure the mRNA expression levels of miR-204 and brain-derived neurotrophic factor (BDNF) in the hippocampus. Nissl staining and TUNEL staining were used to observe the number of Nissl bodies and the apoptosis of cells in the hippocampus. Western blot was used to measure the expression levels of BDNF/TrkB signaling pathway-related proteins in the hippocampus. Results Compared with the control group, the model group had a significant increase in the escape latency and a significant reduction in the number of platform crossings (P<0.001). The model group also had significant increases in the apoptosis rate of cells and the expression level of miR-204 in hippocampal tissue (P<0.001), while the number of Nissl bodies, the mRNA expression level of BDNF, and the protein expression levels of BDNF, p-TrkB, and p-CREB in the model group were significantly reduced compared with the control group (P<0.001). After inhibition of the expression of miR-204, the number of Nissl bodies, the mRNA expression level of BDNF, and the protein expression levels of BDNF, p-TrkB, and p-CREB significantly increased, while the cell apoptosis rate and the expression level of miR-204 in the hippocampus significantly decreased. The escape latency was also reduced, while the number of platform crossings increased after inhibition of the expression of miR-204 (P<0.001). Conclusions Inhibiting miR-204 can improve the learning and memory functions of neonatal rats with IUGR, possibly by targeted activation of the BDNF/TrkB signaling pathway.
