Objective To set up and apply a standardized communication system of adolescents and young adults (AYAs) cancer patients,in order to improve AYAs cancer patients' psychological distress and other negative emotions,as well as promote social support and quality of life of patients.Methods A AYAs cancer patients standardized communication system,suitable for China's national conditions,was preliminarily built.Using randomized controlled trials,a total of 171 subjects,selected from 486 cases of AYAs cancer patients,in the Third Xiangya Hospital of Central South University and Hunan Cancer Hospital from August to September in 2016,were intervened with a set of standardized communication system.The Mental Distress Thermometer (DT),Hospital Anxiety and Depression Scale (HADS),Social Support Rating Scale (SSRS) and Concise Health Status Questionnaire (SF-36) were used as evaluation indexes to observe the psychological distress,emotion,social support and quality of life of the three groups of subjects before intervention,immediately after intervention,1 month after intervention and 3 months after intervention.Results At the follow-up of 3 months after intervention,38 cases were lost,14 cases in communication group (final n =43),11 cases in music therapy group (final n =46),and 13 cases in routine group (final n =44)..There was no significant difference in the evaluation indexes between the communication group,music treatment group and the routine group before intervention (P ＞ 0.05).There were statistically significant differences in scores of psychological pain,anxiety and depression,and social support in the 3 groups,before and immediately after intervention,1 month and 3 months after intervention (P ＜ 0.05).The scores of psychological pain,anxiety and depression,social support and quality of life in the communication group 1 month after intervention were statistically significant compared with those in the music group and the routine group (P ＜ 0.05).Conclusions Compared to music therapy and regular care,the standardized communication system has significant effect on improving the psychological distress of AYAs with cancer,and can also improve their social support level and quality of life.The clinical validation of the standardized communication system can provide reference for psychological rehabilitation of cancer survivors.

2019 novel coronavirus(2019-nCoV) outbreak is one of the public health emergency of international concern.Since the 2019-nCoV outbreak, China has been adopting strict prevention and control measures, and has achieved remarkable results in the initial stage of prevention and control.However, some imported cases and sporadic regional cases have been found, and even short-term regional epidemics have occurred, indicating that the preventing and control against the epidemic remains grim.With the change of the incidence proportion and the number of cases in children under 18 years old, some new special symptoms and complications have appeared in children patients.In addition, with the occurrence of virus mutation, it has not only attracted attention from all parties, but also proposed a new topic for the prevention and treatment of 2019-nCoV infection in children of China.Based on the second edition, the present consensus further summarizes the clinical characteristics and experience of children′s cases, and puts forward recommendations on the diagnostic criteria, laboratory examination, treatment, prevention and control of children′s cases for providing reference for further guidance of treatment of 2019-nCoV infection in children.

OBJECTIVE: To describe negative conversion and rebound of patients with severe and critical acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection after treatment with Nirmatrelvir/Ritonavir, and to analyze related factors associating with failure of SARS-CoV-2 negative conversion and relapse and prognosis. METHODS: A single center retrospective cohort study was conducted. Patients aged ≥ 16 years old who were diagnosed with severe or critical SARS-CoV-2 infection and took Nirmatrelvir/Ritonavir for 5 days in Peking University First Hospital from December 7, 2022 to January 27, 2023, were included. General characteristics and clinical data were collected from electronic medical record system. The Kaplan-Meier curve of SARS-CoV-2 negative conversion was drawn. Factors with P < 0.10 were incorporated into multivariate Logistic regression model to analyze the relationship between the factors and persistent nucleic acid positive and rebound. RESULTS: A total of 31 severe and 37 critical SARS-CoV-2 infection patients were included. The median duration from initiation of Nirmatrelvir/Ritonavir to negative conversion of SARS-CoV-2 for both was 6.0 days, and the negative conversion rate on day 15 was 93.5% and 86.5%, respectively. SARS-CoV-2 rebound was observed in 7 patients (11.3%), among whom were 1 severe patient and 6 critical patients. The above 7 patients with SARS-CoV-2 rebound and 6 patients with failure of SARS-CoV-2 negative conversion were compared with 55 patients with persistent negative conversion. Factors with P < 0.10, including the lowest lymphocyte count (LYM), the highest D-dimer, the highest procalcitonin (PCT), the lowest Ct value, cardiovascular diseases other than hypertension and coronary heart disease, were incorporated into multivariate Logistic regression analysis. The decreased LYM [odds ratio (OR) = 0.146, 95% confidence interval (95%CI) was 0.031-0.689, P = 0.015] and the increased PCT (OR = 2.008, 95%CI was 1.042-3.868, P = 0.037) were revealed to be independent risk factors of the failure of SARS-CoV-2 negative conversion or rebound. The proportion of mechanical ventilation and invasive ventilation were significantly higher in patients with persistent SARS-CoV-2 infection or rebound than those in patients with SARS-CoV-2 negative conversion (84.6% vs. 38.2%, 69.2% vs. 25.5%, both P < 0.01), but no significant difference in mechanical ventilation and invasive ventilation duration was observed. Compared with the patients with SARS-CoV-2 negative conversion, more patients with persistent SARS-CoV-2 infection or rebound were admitted to intensive care unit (ICU, 76.9% vs. 50.9%), and length of ICU stay in patients with persistent SARS-CoV-2 infection or rebound tended to be longer [days: 13.0 (10.3, 24.3) vs. 11.0 (5.3, 23.0), P > 0.05]. CONCLUSIONS The decreased LYM and increased PCT are independent risk factors for the failure of SARS-CoV-2 negative conversion or rebound in patients with severe and critical SARS-CoV-2 infection. Attention should be paid to these patients for their poor prognosis.

At present, severe acute respiratory syndrome coronavirus-2(SARS-CoV-2)infection is still rampant worldwide.As of September 10, 2021, there were about 222 million confirmed cases of corona virus disease 2019(COVID-19)and more than 4.6 million deaths worldwide.With the development of COVID-19 vaccines and the gradual vaccination worldwide, the increasing number of cases in children and unvaccinated young people has drawn attention.According to World Health Organization surveillance data, the proportion of COVID-19 infection cases in children gradually increased, and the proportion of cases in the age groups of under 5 years and 5-14 years increased from 1.0% and 2.5% in January 2020 to 2.0% and 8.7% in July 2021, respectively.At present, billions of adults have been vaccinated with various COVID-19 vaccines worldwide, and their protective effects including reducing infection and transmission, reducing severe disease and hospitalization, and reducing death, as well as high safety have been confirmed.Canada, the United States, Europe and other countries have approved the emergency COVID-19 vaccination in children and adolescents aged 12 to 17 years, and China has also approved the phased vaccination of COVID-19 vaccination in children and adolescents aged 3 to 17 years. For smooth advancement and implementation of COVID-19 vaccination in children, academic institutions, including National Clinical Research Center for Respiratory Diseases, National Center for Children′s Health, and The Society of Pediatrics, Chinese Medical Association organized relevant experts to reach this consensus on COVID-19 vaccination in children.

Severe acute respiratory syndrome coronavirus-2(SARS-CoV-2)infection is still worldwide.As a vulnerable group, severe and dead pediatric cases are also reported.Under this severe epidemic situation, children should be well protected.With the widespread vaccination of SARS-CoV-2 vaccine in adults, the infection rate have decreased.Therefore, SARS-CoV-2 vaccine inoculation for children groups step by step is of great significance to the protection of children and the prevention and control of corona virus disease 2019(COVID-19) as a whole.But the safety of children vaccinated with SARS-CoV-2 vaccine is a main concern of parents.Therefore, in order to ensure the safety of vaccination and the implementation of vaccination work, National Clinical Research Center for Respiratory Diseases, National Center for Children′s Health and the Society of Pediatrics, Chinese Medical Association organized experts to interpret the main issue of parents about SARS-CoV-2 vaccine for children, in order to answer the doubts of parents.

China has classified the Corona Virus Disease 2019(COVID-19) as a statutory category B infectious disease and managed it according to Category B since January 8, 2023.In view that Omicron variant is currently the main epidemic strain in China, in order to guide the treatment of severe acute respiratory syndrome coronavirus 2(SARS-CoV-2) infection in children with the times, refer to the Diagnosis and Treatment Protocol for Novel Coronavirus Infection (Trial 10 th Edition), Expert Consensus on Diagnosis, Treatment and Prevention of Novel Coronavirus Infection in Children (Fourth Edition) and the Diagnosis and Treatment Strategy for Pediatric Related Viral Infections.The Expert Consensus on the Diagnosis, Treatment and Prevention of Novel Coronavirus Infection in Children (Fifth Edition) has been formulated and updated accordingly on related etiology, epidemiology, pathogenic mechanism, clinical manifestations, auxiliary examination, diagnosis and treatment, and added key points for the treatment of COVID-19 related encephalopathy, fulminating myocarditis and other serious complications for clinical reference.

Monkeypox is a zoonotic disease.Previous studies have shown that children are vulnerable to monkeypox and are also at high risk for severe disease or complications.In order to improve pediatricians′ understanding of monkeypox and achieve early detection, early diagnosis, early treatment and early disposal, the committee composed of more than 40 experts in the related fields of infectious diseases, pediatrics, infection control and public health formulate this expert consensus, on the basis of the latest clinical management and infection prevention and control for monkeypox released by the World Health Organization (WHO), the guidelines for diagnosis and treatment of monkeypox (version 2022) issued by National Health Commission of the People′s Republic of China and other relevant documents.During the development of this consensus, multidisciplinary experts have repeatedly demonstrated the etiology, epidemiology, transmission, clinical manifestations, laboratory examinations, diagnosis and differential diagnosis, treatment, discharge criteria, prevention, case management process and key points of prevention and control about monkeypox.

Since December 2019, severe acute respiratory syndrome coronavirus 2(SARS-CoV-2) infections have raged globally for more than 2 years.China has always adopted scientific and effective prevention and control measures to achieved some success.However, with the continuous variation of SARS-CoV-2 cases and imported cases from abroad, the prevention and control work has become more difficult and complex.With the variation of the mutant strain, the number of cases in children changed, and some new special symptoms and complications were found, which proposed a new topic for the prevention and treatment of SARS-CoV-2 infection in children in China.Based on the third edition, the present consensus according to the characteristics of the new strain, expounded the etiology, pathology, pathogenesis, and according to the clinical characteristics and experience of children′s cases, and puts forward recommendations on the diagnostic criteria, laboratory examination, treatment, prevention and control of children′s cases for providing reference for further guidance of effective prevention and treatment of SARS-CoV-2 infection in children in China.

Objective: To investigate the incidence of post-bronchiolitis recurrent wheezing and its risk factors in children. Methods: This study was conducted on patients with bronchiolitis admitted to the Department of Respiratory Disease, Children′s Hospital of Soochow University between November 2016 and March 2017.Nasopharyngeal secretions were taken from all patients and assessed for respiratory pathogens.After discharge, the patients were followed up every 3 months by outpatient visit or telephone call for 1 year. Results: Eighty-nine patients with bronchiolitis were enrolled in this study.Among those 89 patients, respiratory syncytial virus(RSV) infection accounted for 46.1%(41/89 cases), Mycoplasma pneumonia(MP) for 5.6%(5/89 cases), rhinovirus(RV) for 4.5%(4/89 cases), and human bocavirus(hBoV) for 2.2%(2/89 cases). Eighty-three patients were successfully followed up.At the 3, 6, 9, and 12 months of follow-up, the occurrence of wheezing episodes for only once happened in 20 cases(24.1%), 27 cases(32.5%), 35 cases (42.2%), and 38 cases(45.8%), respectively.At 12 months after initial bronchiolitis, the occurrence of wheezing episodes for only once happened in 21 cases(25.3%), 2 episodes of wheezing in 10 cases(12.0%), and 7 cases (8.4%) had more than 3 episodes of wheezing, and 6 cases lost follow-up.The proportion of eczema and milk-protein allergy in post-bronchiolitis recurrent wheezing group was significantly higher than that of the group with not post-bronchiolitis recurrent wheezing patients (χ²=6.219, 4.855, all P<0.05). Logistic regression analysis showed eczema was the independent risk factor for post-bronchiolitis recurrent wheezing(OR=0.189, 95%CI: 0.047-0.765). There were no significant difference in gender, age, premature birth, birth weight, feeding pa-tterns, family history of asthma, pet contact history, severity of disease, course of disease, total immunoglobulin E of serum and the species of virus infected between 2 groups(all P>0.05). Conclusions The incidence of recurrent wheezing among post-bronchiolitis patients is higher during one-year follow-up period.Eczema is the independent risk factor for post-bronchiolitis recurrent wheezing.The specific pathogens and severity of disease have no correlation with post-bronchiolitis wheezing.
