ABSTRACT
Objective:To assess the clinical effectiveness and safety of Omalizumab for treating pediatric allergic asthma in real world in China.Methods:The clinical data of children aged 6 to 11 years with allergic asthma who received Omalizumab treatment in 17 hospitals in China between July 6, 2018 and September 30, 2020 were retrospectively analyzed.Such information as the demographic characteristics, allergic history, family history, total immunoglobulin E (IgE) levels, specific IgE levels, skin prick test, exhaled nitric oxide (FeNO) levels, eosinophil (EOS) counts, and comorbidities at baseline were collected.Descriptive analysis of the Omalizumab treatment mode was made, and the difference in the first dose, injection frequency and course of treatment between the Omalizumab treatment mode and the mode recommended in the instruction was investigated.Global Evaluation of Treatment Effectiveness (GETE) analysis was made after Omalizumab treatment.The moderate-to-severe asthma exacerbation rate, inhaled corticosteroid (ICS) dose, lung functions were compared before and after Omalizumab treatment.Changes in the Childhood Asthma Control Test (C-ACT) and Pediatric Asthma Quality of Life Questionnaire (PAQLQ) results from baseline to 4, 8, 12, 16, 24, and 52 weeks after Omalizumab treatment were studied.The commodity improvement was assessed.The adverse event (AE) and serious adverse event (SAE) were analyzed for the evaluation of Omalizumab treatment safety.The difference in the annual rate of moderate-to-severe asthma exacerbation and ICS reduction was investigated by using t test.The significance level was set to 0.05.Other parameters were all subject to descriptive analysis.A total of 200 allergic asthma patients were enrolled, including 75.5% ( n=151) males and 24.5% ( n=49) females.The patients aged (8.20±1.81) years. Results:The median total IgE level of the 200 patients was 513.5 (24.4-11 600.0) IU/mL.Their median treatment time with Omalizumab was 112 (1-666) days.Their first dose of Omalizumab was 300 (150-600) mg.Of the 200 cases, 114 cases (57.0%) followed the first Omalizumab dosage recommended in the instruction.After 4-6 months of Omalizumab treatment, 88.5% of the patients enrolled ( n=117) responded to Omalizumab.After 4 weeks of treatment with Omalizumab, asthma was well-controlled, with an increased C-ACT score [from (22.70±3.70) points to (18.90±3.74) points at baseline]. Four-six months after Omalizumab administration, the annual rate of moderate-to-severe asthma exacerbation had a reduction of (2.00±5.68) per patient year( t=4.702 5, P<0.001), the median ICS daily dose was lowered [0 (0-240) μg vs. 160 (50-4 000) μg at baseline] ( P<0.001), the PAQLQ score was improved [(154.90±8.57) points vs. (122.80±27.15) points at baseline], and the forced expiratory volume in one second % predicted (FEV 1%pred) was increased [(92.80±10.50)% vs. (89.70±18.17)% at baseline]. In patients with available evaluations for comorbidities, including allergic rhinitis, atopic dermatitis or eczema, urticaria, allergic conjunctivitis and sinusitis, 92.8%-100.0% showed improved symptoms.A total of 124 AE were reported in 58 (29.0%) of the 200 patients, and the annual incidence was 0(0-15.1) per patient year.In 53 patients who suffered AE, 44 patients (83.0%) and 9 patients (17.0%) reported mild and moderate AE, respectively.No severe AE were observed in patients.The annual incidence of SAE was 0(0-1.9) per patient year.Most common drug-related AE were abdominal pain (2 patients, 1.0%) and fever (2 patients, 1.0%). No patient withdrew Omalizumab due to AE. Conclusions:Omalizumab shows good effectiveness and safety for the treatment of asthma in children.It can reduce the moderate-to-severe asthma exacerbation rate, reduce the ICS dose, improve asthma control levels, and improve lung functions and quality of life of patients.
ABSTRACT
Bronchial asthma is a heterogeneous disease characterized by chronic airway inflammation and airway hyperresponsiveness. With the development of the whole-life-cycle health concept, the focus of treatment for bronchial asthma in children has gradually shifted from initial pharmacological control to an integrated management model of functional rehabilitation and pharmacological assistance. As a non-pharmacological integrated approach, pulmonary rehabilitation plays an equally important role in the management of childhood asthma as pharmacological treatment. Studies have shown that breathing techniques such as Buteyko breathing, pursed lip breathing, diaphragmatic breathing training, threshold-pressure inspiratory muscle training and yoga breathing can improve lung function indicators such as FEV1, FVC, PEF and MVV in children. The comprehensive pre-exercise assessment, the development of exercise prescriptions, and the implementation and evaluation of exercise effects can improve the physical fitness, neuromuscular coordination and self-confidence of children with asthma. The comprehensive interventions of health education, psychological support and nutritional intervention can improve the compliance and effectiveness of rehabilitation training. This article reviews the research progress on respiratory training, physical exercise and comprehensive interventions in the pulmonary rehabilitation of asthmatic children, to provide theoretical basis and practical guidance for the scientific and rational management of pulmonary rehabilitation of asthmatic children in clinical settings.

ABSTRACT
Objective:To investigate the knowledge, attitudes, and practices (KAP) of pulse oximetry among pediatric healthcare providers in China and analyze the factor influencing the KAP.Methods:A self-developed questionnaire was used for an online research on the KAP of 11 849 pediatric healthcare providers from 31 provinces, autonomous regions, and municipalities of China from March 11 to 14, 2022.The factors influencing the KAP of pulse oximetry among pediatric healthcare providers were examined by Logistic regression. Results:The scores of KAP, of pulse oximetry were 5.57±0.96, 11.24±1.25 and 11.19±4.54, respectively.The corresponding scoring rates were 69.61%, 74.95%, and 55.99%, respectively. Logistic regression results showed that the gender and working years of pediatric healthcare providers, the region they were located, and whether their medical institution was equipped with pulse oximeters were the main factors affecting the knowledge score (all P<0.05). Main factors influencing the attitude score of pediatric healthcare providers included their knowledge score, gender, educational background, working years, region, medical institution level, and whether the medical institution was equipped with pulse oximeters (all P<0.05). For the practice score, the main influencing factors were the knowledge score, gender, age, and whether the medi-cal institution was equipped with pulse oximeters (all P<0.05). Conclusions:Chinese pediatric healthcare providers need to further improve their knowledge about and attitudes towards pulse oximetry.Pulse oximeters are evidently under-used.It is urgent to formulate policies or guidelines, strengthen education and training, improve knowledge and attitudes, equip more institutions with pulse oximeters, and popularize their application in medical institutions.

ABSTRACT
Objective:To analyze the characteristics of lung function in patients with spinal muscular atrophy (SMA) to provide evidence for multidisciplinary management of SMA.Methods:A total of 30 patients with SMA treated in the SMA multidisciplinary clinic of the Children′s Hospital, Zhejiang University School of Medicine from July 2019 to March 2021 were enrolled, including 1 child with type I, 18 patients with type Ⅱ and 11 children with type Ⅲ.There were 17 males and 13 females; the age ranged from 4 years to 21 years and 10 months old.A retrospective study was conducted to analyze the clinical features, spinal imaging findings and lung functions of patients with different clinical types of SMA and explore the factors influencing the lung functions of patients with SMA.Pulmonary function was measured by forced expiratory flow-volume curve.Forced vital capacity (FVC), forced expiratory volume in one second (FEV 1), FEV 1/FVC and peak expiratory flow (PEF) were measured.The results were expressed as the percentage of the measured value to predicted value.The Cobb angle was measured to evaluate scoliosis. Pearson correlation analysis and multiple linear regression analysis were used to evaluate the relationship between lung function and age and Cobb angle in patients with type Ⅱ SMA. Pearson correlation analysis and univariate linear regression analysis were used to evaluate the relationship between Cobb angle and age in patients with type Ⅱ SMA. Results:Pulmonary function in 1 type I patient showed decreased FVC and FEV 1; Among 18 patients with type Ⅱ, 14 cases had abnormal lung function (77.8%): FVC decreased in 12 patients (66.7%), FEV 1 decreased in 10 patients (55.6%), PEF decreased in 12 patients (66.7%). Among 11 patients with type Ⅲ, one had decreased FVC (9.1%). FVC, FEV 1 and PEF of patients with type Ⅱ were significantly lower than those of patients with type Ⅲ [(62.4±31.8)% vs.(90.8±11.0)%, (66.3±33.3)% vs.(97.8±9.9)%, (65.3±30.1)% vs.(98.6±21.1)%, all P<0.01]. Pearson correlation analysis showed that FVC of patients with type Ⅱ SMA was correlated with age and Cobb angle ( r=-0.864, -0.865, all P<0.001), FEV 1 was correlated with age and Cobb angle ( r=-0.878, -0.863, all P<0.001), PEF was correlated with age and Cobb angle ( r=-0.831, -0.783, all P<0.001), and Cobb angle was related to age ( r=0.922, P<0.001). Multiple linear regression analysis indicated that FVC of patients with type Ⅱ SMA was linearly correlated with Cobb angle ( R2=0.748, P<0.001), FEV 1 was linearly correlated with age ( R2=0.770, P<0.001), PEF was linearly related to age ( R2=0.690, P<0.001). Univariate linear regression analysis revealed that Cobb angle of patients with type Ⅱ SMA was linearly related to age ( R2=0.851, P<0.001). Conclusions:FVC, FEV 1 and PEF may decrease in patients with SMA.The degree of lung function damage is different in different types of SMA patients.With the increase of age, Cobb angle increases and FVC, FEV 1 and PEF decrease in patients with type Ⅱ SMA.Understanding the factors influencing the pulmonary function damage in patients with SMA is conductive to carrying out individual multidisciplinary management.
ABSTRACT
Objective:To explore the clinical effects and adverse reactions of hydromorphone versus morphine subcutaneous injection analgesia for cancer outbreak pain.Methods:A total of 98 patients with cancer outbreak pain admitted to Xuzhou Central Hospital were selected. According to the random number table method, the patients were divided into the observation group (receiving subcutaneous injection of hydromorphone for analgesia) and the control group (receiving subcutaneous injection of morphine for analgesia), 49 cases in each group. The numerical rating scale (NRS) scores and quality of life (QOL) scores, pain relief effects, serum β-endorphin, substance P, 5-hydroxytryptamine levels and the incidence of adverse reactions were compared between the two groups.Results:The NRS scores of the two groups after treatment were decreased compared with those before treatment (all P < 0.05); and the NRS score of the observation group was lower than that of the control group after treatment [(2.4±0.4) scores vs. (3.2±0.5) scores, t = 8.69, P < 0.001]; the QOL scores of the two groups after treatment were higher than those before treatment (all P < 0.05); and there were no statistically significant difference in QOL scores after treatment between the two groups [(46±7) scores vs. (43±7) scores, t = 1.62, P = 0.109]. The total effective rate of pain relief of the observation group was higher than that of the control group [93.88% (46/49) vs.79.59% (39/49), χ2 = 4.35, P = 0.037]. The serum β-endorphin, substance P, 5-hydroxytryptamine levels of the two groups after treatment were decreased compared with those before treatment (all P < 0.05). β-endorphin, substance P and 5-hydroxytryptamine of the observation group were lower than those of the control group after treatment[β-endorphin: (85±15) ng/L vs. (98±17) ng/L, substance P: (2.1±0.3) μg/ml vs. (2.4±0.4) μg/ml, 5-hydroxytryptamine: (0.31±0.05) ng/L vs.(0.38±0.06) ng/L; t values were 3.75, 3.63, 6.27, all P < 0.05). Compared with the control group, the incidence of adverse reactions like skin pruritus, nausea and vomiting of the observation group were lower (all P < 0.05). Conclusions:Compared with subcutaneous injection of morphine for analgesia, hydromorphone can better alleviate the pain of patients with cancer outbreak pain, decrease the level of pain mediators, and reduce the incidence of skin pruritus, nausea and vomiting.
ABSTRACT
Mycoplasma pneumoniae is an important pathogen of community-acquired pneumonia in children.Although Mycoplasma pneumoniae infection is likely to be self-limited, severe or refractory cases of Mycoplasma pneumoniae pneumonia are increasing, with severe condition and prolonged course, prone to pulmonary and extra-pulmonary complications, some with sequelae, which challenges the treatment.Here, we reviewed the therapeutic progress of Mycoplasma pneumoniae pneumonia.

The clinical manifestation, laboratory results, imaging findings, diagnosis and treatment were summarized.@*Results@#Among these 8 cases, aged from 9 hours to 14 years and 10 months. Fever was found in 4 cases, cough aggravation in 4, short of breath in 3, chest pain in 2, abdominal and back pain in one, hemoptysis in 2, cyanosis in 1, and edema of lower extremities in 2. Physical examination found decreased breath sound in 2 cases, phlegm rale in 3, and pleural friction rub in one. Pleural effusion was found in 5 cases by ultrasound. Plasma D-dimer increased in 6 cases (0.66-9.96 mg/L) and hypersensitive C-reactive protein elevated in 5 cases (10.78-78.00 mg/L). Chest enhanced CT showed pulmonary artery or venous filling defects, including pulmonary artery embolism in 7 cases and pulmonary vein embolism in one. The primary disease of these patients included Mycoplasma Pneumoniae pneumonia in 4 cases, nephritis in 2 and postoperative congenital heart disease in 2. Apart from one case who withdrew the treatment and was discharged, the other 7 patients received anticoagulant treatment had good outcome.@*Conclusions@#For children with Mycoplasma pneumoniae pneumonia, immune disorders, long-term hormone therapy, cardiovascular invasive operation or other high-risk factors, PTE should be considered when fever, cough aggravation, short of breath, chest and back pain with pleural effusion are present. Chest enhanced CT scan should be performed as soon as possible, and anticoagulation should be started once the diagnosis is confirmed.
ABSTRACT
The coronavirus disease 2019 (COVID-19) has caused a global pandemic. All people including children are generally susceptible to COVID-19, but the condition is relatively mild for children. The diagnosis of COVID-19 is largely based on the epidemiological evidence and clinical manifestations, and confirmed by positive detection of virus nucleic acid in respiratory samples. The main symptoms of COVID-19 in children are fever and cough; the total number of white blood cell count is usually normal or decreased; the chest imaging is characterized by interstitial pneumonia, which is similar to other respiratory virus infections and infections. Early identification, early isolation, early diagnosis and early treatment are important for clinical management. The treatment of mild or moderate type of child COVID-19 is mainly symptomatic. For severe and critical ill cases, the oxygen therapy, antiviral drugs, antibacterial drugs, glucocorticoids, mechanical ventilation or even extracorporeal membrane oxygenation (ECMO) may be adopted, and the treatment plan should be adjusted timely through multi-disciplinary cooperation.

Objective:To investigate the characteristics and differences of anxiety, depression and sleep disorder among human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) patients in Guangzhou, then optimize the antiretroviral therapy and provide effective mental intervention.Methods:All HIV/AIDS patients from the outpatient department of Guangzhou Eighth People's Hospital were enrolled in the present study from January 2016 to December 2016. They were evaluated by the hospital anxiety and depression scale and Pittsburgh Sleep Quality Index, to analyze the levels of depression, anxiety and sleep disorder.Results:The incidences of anxiety, depression and sleep disorder were 30.5%(61/200), 31.0%(62/200) and 22.5%(45/200) respectively. 36.1%(22/61) of patients with anxiety and 35.5%(22/62) of patients with depression were accompanied by sleep disorder. The sleep disturbance index were significant higher in HIV/AIDS patients with anxiety ( t=4.065, P<0.001) or depression ( t=3.034, P=0.003) than those without anxiety or depression. Anxiety was mainly found in HIV/AIDS patients in aged 20 to 40 group ( F=7.998, P=0.018), while depression was mostly found in HIV/AIDS patients who didn't receive higher education ( F=13.55, P=0.001), and sleep disorder was more common in people with CD4 + count <200 cells/μl ( t=2.01, P=0.046). Conclusions:Anxiety and depression, which could aggravate sleep disorder, are very common in HIV/AIDS patients. Psychological care need to be strengthened to HIV positive patients in early phase, and screening questionnaires should be conducted before antiretroviral treatment began.
ABSTRACT
Asthma is a common chronic airway inflammatory disease in children.Currently, symptomatic control can be achieved in the majority of patients through a combination of β 2 receptor agonists for rapid relief of symptoms and inhaled corticosteroids for long-term control.As the only causal treatment modality at present, allergen-specific immunotherapy (AIT) may modify the natural course of asthma, and can control the symptoms, reduce airway hyperresponsiveness and improve lung function.In order to provide evidence for improving the effect of AIT on asthma, the mechanism of AIT in asthma and its effect on lung function were discussed in this paper.
ABSTRACT
December 2019 witnessed the outbreak of COVID-19 in Wuhan, Hubei province of China, which soon spread nationwide and across national borders to pose a menacing pandemic threat. Children are themselves highly susceptible to infectious diseases in normal times not to mention an epidemic. Coupled with the high incidence of seasonal influenza, it is imperative to strengthen epidemiological screening of children, along with effective isolation, treatment, prevention and control measures. In view of the specifics of the hospital, the authors proposed to further improve the medical emergency procedure, for strictly enforcing screening and isolation regulations, and standardizing medical procedure. They also proposed scientific layout and use of the infection wards. All these measures are designed to control the epidemic and protect the safety of children, families and medical staff.
ABSTRACT
The epidemic of COVID-19 has become the topmost public health threat worldwide. The authors suggested that in addition to strengthening the organization and leadership of the abovementioned work, greater attention be paid to establishing and improving the prevention and control mechanism.Furthermore, special efforts should be given to the safety of the medical workers, by strengthening their infection monitoring and outbreak management. Medical workers in different work areas and positions should be placed under careful protection with due cleaning and disinfection measures. The protection during specimen collection, transportation and medical waste management should also be prioritized. Such special issues in the management of pediatric patients, as allocation of nurses, the screening and management of caregivers, the problem of breastfeeding, and the disinfection of children′s toys and diapers were discussed. This paper also put forward management suggestions for the outpatient department, isolation ward and other key departments, which aim to guide the prevention and control of COVID-19 nosocomial infection in the pediatric outpatient and ward.
