Clinical epidemiology of adenovirus pneumonia among Chinese hospitalized children.

Adenovirus pneumonia is a prevalent form of community-acquired pneumonia among children. Research on the epidemiology and economic burden of this disease is crucial for public health, yet comprehensive data remains scarce, making it crucial to highlight on this topic. In this study, the data were extracted from the face sheet of discharge medical records collected from 26 tertiary children's hospitals from January 2016 to December 2021. In total, 1854 children with laboratory-confirmed adenovirus pneumonia were hospitalized, accounting for 0.13% of the total number of hospitalized for pneumonia in the database during the period. In addition, this figure represents a meager 0.027% when compared to the total number of hospitalized children. The male-to-female ratio was 1.78:1. The 1-3-year age group had the highest number of inpatients for adenoviral pneumonia and the largest proportion of the total hospitalizations in the same age group. Overall, winter is the primary season for the prevalence of adenovirus pneumonia, however, in southern China, there are two peak seasons, winter and summer. Although patients with 3/4 adenovirus pneumonia had no significant complications, some patients had complications such as respiratory failure, diarrhea, and myocardial damage. The median length of stay of adenovirus pneumonia was 8 d [interquartile range (IQR) 6-11], and the median hospitalization cost was 1293.83 United States dollars (IQR 811.81-2472.51). These valuable epidemiological insights into adenovirus pneumonia in Chinese children can help direct the development of targeted prevention and control strategies and surveillance measures for HAdV infections in this demographic.

Clinical epidemiology and disease burden of adenoviral encephalitis in hospitalized children in China: A nationwide cross-sectional study.

Importance: Adenovirus encephalitis is a significant infectious disease of the central nervous system that commonly affects children under the age of 5 and has a profound impact on the health of infants and young children throughout China. National multicenter epidemiological studies have significant public health implications. Objective: This study aims to report the epidemiology of adenovirus encephalitis in hospitalized children in China, providing valuable guidance for clinicians. Methods: The data utilized in this study were extracted from the comprehensive Futang Update Medical Records database, which comprises discharge medical records collected by 27 tertiary children's hospitals between January 2016 and December 2018 in China. Specifically, the face sheet of discharge medical records encompassed critical sociodemographic variables and basic medical care details. Results: In this database, a total of 544 children were hospitalized due to adenoviral encephalitis. The male-to-female ratio was 1.62:1, with more boys being affected across different age groups and places of residence. Of the children hospitalized, the highest number of hospitalizations occurred in the 1-3-year age group and the number of hospitalizations decreased each year from 2016 to 2018. The disease exhibits seasonal characteristics with a pronounced peak in the summer months of June and July. While most children (58%) did not have any significant complications, one-third of them developed respiratory complications, including pneumonia and acute bronchitis. The median length of stay for adenoviral encephalitis was 7 days, and the median cost of hospitalization was 2145.56 US dollars. Interpretation: This study highlights the prevalence of adenovirus encephalitis in hospitalized children in China. Children aged 1-3 years were found to be the main demographic hospitalized due to this condition, with boys being significantly more affected than girls. The seasonal variations of adenovirus encephalitis were also found to be significant. Fortunately, the fatality rate associated with this condition was low, and the prognosis was generally favorable.

Experience with the management of 2599 cases of congenital muscular torticollis and a multicenter epidemiological investigation in 17 hospitals in China.

BACKGROUND: Congenital muscular torticollis (CMT) is a common musculoskeletal disease affecting infants and young children. If CMT is not treated correctly and timely, it can lead to limited head and neck movements, head and neck deviation, and abnormal posture. In order to improve patients' symptoms and alleviate the negative impact of the disease on their lives, we are committed to exploring the treatment of CMT. METHODS: The general clinical and ultrasonographic data of 2599 children with CMT who received standardized treatment at Shenzhen Children's Hospital from 2004 to 2020 were retrospectively reviewed. According to given treatment, children with CMT were divided into the physiotherapy group, physiotherapy combined with glucocorticoid treatment group, and surgical treatment group. We divided children with CMT into local mass, uniform thickening, and atrophy according to ultrasound features. General clinical information, treatment, and ultrasound examination data in each group were compared. Additionally, electronic medical records of 2344 patients admitted due to CMT in 17 tertiary children's hospitals of China's Futang Research Center of Pediatric Development (FRCPD) from 2015 to 2019 were retrospectively analyzed. Data on sex, age, year of admission and discharge, and treatment costs during hospitalization were extracted from the first medical record pages according to the ICD codes. The data were assessed for normality using the Kolmogorov-Smirnov test. Depending on the data distribution, they were analyzed using parametric tests, such as the t-test, or non-parametric tests. Qualitative data are expressed as percentages (%) and analyzed using the chi-square or Fisher's exact probability test, with α = 0.05 as the test level. P < 0.05 was considered to be indicative of a statistically significant difference. RESULTS: Three types of CMT were defined based on sternocleidomastoid muscle ultrasound examination characteristics: local mass, uniform thickening, and atrophy. Age at first diagnosis was 69.21 ± 108.41 days in local mass type group, 216.85 ± 324.09 days in uniform thickening group, and 417.88 ± 739.05 days in atrophy- type group; while age at first physiotherapy use was 94.06 ± 206.49 days, 255.00 ± 430.62 days, 540.92 ± 1059.29 respectively. The children included in local mass type group have shown a high success rate of conservative treatment, with a rate of 7.5% of children underwent surgery. Age at first diagnosis was 112.44 ± 224.12 days in the physiotherapy group, 115.87 ± 144.86 days in the physiotherapy combined with glucocorticoid treatment subgroup, whereas the age at first physiotherapy use was 137.38 ± 312.11 and 196.91 ± 344.26 days respectively. In the observation period (2015-2019) the mean age at surgery for CMT in 17 tertiary children's hospitals of the FRCPD was 50 months. Overall, 663 children with CMT were 1-2 years of age, accounting for the largest proportion (28.3%). Followed by 417 individuals (17.8%) were 7-14 years of age, indicating that there are still more children with CMT receiving surgical treatment later. CONCLUSIONS: Early diagnosis and treatment are essential to improve the conservative treatment success rate and achieve good prognosis in children with CMT. Our team's concept for treating CMT is as follows: after diagnosing the children, we will adopt the standardized protocol of treatment, with physiotherapy combined with the injection of glucocorticoid drugs and SCM release surgery, when needed. This program has a high conservative treatment success rate and may facilitate the achievement of better prognosis and reduced teratogenicity rate.

Scientific landscape and trend analysis of chronic urticaria: a two-decade bibliometric review.

BACKGROUND: In the past 20 years, an increasing number of studies have advanced our understanding of the pathogenic mechanism of chronic urticaria (CU), providing new treatment options. OBJECTIVES: This bibliometric study aimed to evaluate published reports of CU-related studies from a number of different angles, review the research trends of the studies, and provide future perspectives of CU. MATERIALS & METHODS: Publications related to CU from 2001-2022 were searched in the Web of Science Core Collection. The database file was imported to Excel and analysed using bibliometric software, including VOSviewer and BiblioShiny. RESULTS: A total of 4,452 publications of CU were included. The number of publications related to CU has increased steadily over time. The journal with the most published articles was Allergy, and the countries with the most publications were the United States, Germany, and Italy. The most productive author was Maurer Marcus from Germany. There was close co-authorship between authors and countries (and regions) across the world. Recent studies have focused more on the pathogenesis and treatment of CU. Future hotspots may include emerging biologics for treatment. CONCLUSION: This study shows the research development of CU over the past two decades, which may provide beneficial reference for publication and future trends in CU research.

Association of risk of incident acne and treatment with systemic Janus kinase inhibitors in atopic dermatitis: a systematic review and meta-analysis.

INTRODUCTION: The therapeutic efficacy of systemic Janus kinase (JAK) inhibitors in moderate-to-severe atopic dermatitis (AD) is well established. However, the associated risk of incident acne, which is a prevalent adverse event in AD patients treated with systemic JAK inhibitors, has yet to be systematically analyzed. METHODOLOGY: To evaluate the risk of incident acne in AD patients treated with systemic JAK inhibitors, an extensive database search (clinicaltrials.gov, PubMed) was performed to identify publications eligible for inclusion from January 2020 to October 2022. Five randomized clinical trials (RCTs) of abrocitinib, four RCTs of upadacitinib, and one RCT of baricitinib, encompassing a total of 7901 participants, were included in the analysis. The risk difference for incident acne between systemic JAK inhibitors and controls was assessed using Review Manager, version 5.3, adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. RESULTS: Meta-analysis elucidated a significant difference in the risk of incident acne between AD participants receiving 200 mg abrocitinib (Mantel-Haenszel risk difference, 3.69; 95% CI 1.60-8.48; P < 0.01), 15 mg upadacitinib (Mantel-Haenszel risk difference, 4.61; 95% CI 2.79-7.62; P < 0.00001), and 30 mg upadacitinib (Mantel-Haenszel risk difference, 6.82; 95% CI 4.59-10.13; P < 0.00001) compared with controls receiving placebo or dupilumab. In contrast, no significant difference was found in the risk of incident acne between participants receiving 100 mg abrocitinib, 2 mg baricitinib, and 4 mg baricitinib, as compared with controls. CONCLUSIONS: Based on the current evidence, there is an increased risk of acne related to systemic JAK inhibitors, particularly with abrocitinib and upadacitinib. For patients predisposed to acne, the balance between the benefits of symptomatic relief from AD and the potential risk of acne may need to be carefully considered. This study contributes to a nuanced understanding of the risk profile of systemic JAK inhibitors and has the potential to guide personalized treatment decisions for AD patients.

Clinical characteristics of pediatric hypertension: a multicenter study in China.

OBJECTIVES: Hypertension in children has attracted increasing attention. However, clinical-based studies investigating characteristics and secular trends of pediatric hypertension remain limited. This study aimed to investigate the clinical characteristics and secular trends of different types of hypertension among hospitalized children in China. METHODS: This retrospective analysis was based on medical records from nine tertiary children's hospitals in China during 2010∼2020. A total of 5847 pediatric inpatients (aged <18 years) with the diagnosis of hypertension were enrolled. Information on the clinical characteristics of each patient was obtained from their first admission records. RESULTS: During the past decade, secondary hypertension sustained to be the dominant type of hypertension in children, with the proportion increased from 51.2% during 2010∼2015 to 59.8% during 2016∼2020. The main causes of secondary hypertension were neurologic disorders in children aged 0∼2 years, which changed to renal diseases after 3 years of age. Compared with primary hypertension, secondary hypertension was common in girls (43.1 vs. 23.3%) and children under 5 years of age (32.2 vs. 2.1%). Moreover, over four-fifths of primary hypertensive individuals had obesity and obesity-related comorbidities, and the proportion of clusters of one or more comorbidities increased in the past decade (79.7 → 85.2%). CONCLUSION: Secondary hypertension sustained to be the dominant type of hypertension among children, especially in girls. Renal diseases were the most common causes of secondary hypertension in children, followed by rheumatic immune diseases. For primary hypertension, over four-fifths of inpatients had obesity and obesity-related diseases, and the proportion kept rising.

Research interest in the usage of dupilumab for atopic dermatitis: a bibliometric analysis.

BACKGROUND: Recently, dupilumab has been used for the treatment of atopic dermatitis (AD), and growing interest in the subject has resulted in an increasing number of publications. OBJECTIVES: Our study aimed to evaluate the rapid progress, identify hot topics, and explore scientific advances and future trends in this field. MATERIALS & METHODS: The global distribution of publications was estimated with no time restrictions. Dupilumab as a treatment for AD was scanned in the Web of Science core collection using the topic terms "dupilumab" and "atopic Dermatitis". VOSviewer was applied for visualization of bibliometric analysis. Analysis of country and region distribution, impact of journal, authors, population, economic estimation among countries and regions, key words, as well as the top 20 cited articles were performed. RESULTS: In total, 910 publications were yielded from the Web of Science core collection database. Most studies were published in the USA (46.15%), Germany (17.91%), and France (14.07%); other countries included Denmark, the Netherlands, and Canada based on normalization of article numbers according to population and economic evaluation. Studies were most frequently reported in the British Journal of Dermatology and the Journal of the American Academy of Dermatology. Pirozzi, G. from France was the top-cited author. The most frequent key words were concepts in dermatology, allergy, and immunology. Remarkable landmark clinical trials were noted in the top 20 cited publications. CONCLUSION: The research of dupilumab for AD is rapidly developing. Countries in North America and Europe have remarkably contributed to researches of dupilumab as a treatment for AD. The bibliometric analysis also presents hallmark publications reporting scientific advances in therapy progress, which may provide a foundation for further research.

Epidemiological characteristics of paediatric burn patients in China from 2016 to 2019: a retrospective study.

BACKGROUND: Epidemiological characteristics of paediatric burn can help to protect children from burn injuries. Most of the previous studies have been conducted on small scale and single centre in China. This study analysed the epidemiological characteristics of paediatric burn using a large-scale and multicentre database from 23 children's hospitals in China to increase child protection against burn injuries, improve the quality of care and reduce hospitalisation costs. METHODS: Excerpted information from medical records of 6741 paediatric burn cases was extracted from the Futang Research Center of Pediatric Development database from 2016 to 2019. The epidemiological characteristics of patients, including gender, age, cause of burn injuries, complication, the timing of hospitalisation (season and month) and hospitalisation length and cost, were collected. RESULTS: Male gender (63.23%), aged 1-2 years (69.95%), and hydrothermal scald (80.57%) were significantly dominant among cases. Furthermore, complications were significantly different among groups with different age of patients. Pneumonia was the most common complication (21%). Meanwhile, most paediatric burn occurred in spring (26.73%), and hospitalisation length and cost significantly depended on the cause of the burn injuries and surgical intervention. CONCLUSIONS: This large-scale epidemiological study of paediatric burn in China revealed that boys aged 1-2 years with higher activity and lack of self-awareness are more likely to suffer from burn injuries by hydrothermal scald. In addition, complications, especially pneumonia, need attention and early prevention in paediatric burn.

Dupilumab-Associated Psoriasis and Psoriasiform Manifestations: A Scoping Review.

BACKGROUND: Dupilumab is the first approved IL-4Rα inhibitor for the treatment of atopic dermatitis at present with good efficacy and safety. However, there have been several reports of psoriasis and psoriasiform manifestations occurring after dupilumab therapy in recent years, showing a new paradoxical cutaneous reaction associated with biologics. SUMMARY: This is a scoping review in order to summarize the demographics and epidemiology, clinical manifestations, diagnosis, potential pathogenesis, and promising management of dupilumab-associated psoriasis and psoriasiform manifestations.

Skin diseases of the nipple and areola complex: A case series study from China.

Background: Skin diseases of the nipple and areola complex (NAC) are numerous and difficult to diagnose, which is a great challenge for clinicians. A better understanding of the clinical features of NAC skin diseases is of great value for the correct diagnosis. Methods: To investigate the clinical characteristics of skin diseases of the NAC, we retrospectively analyzed the demographic data, disease constitution, rash characteristics, inconsistency between the clinical and pathological diagnosis from 260 patients with NAC lesions that were confirmed by histopathology at Peking Union Medical College Hospital, China from 2012 to 2022. Results: The patients' average age was 43.6 (8 to 82) years, and the ratio of females to males was 13.4:1. Out of the 260 patients biopsied, the most common diseases were eczema, Paget's disease (PD), adenoma of the nipple (AN), seborrheic keratosis (SK), cutaneous metastasis of breast cancer, wart, soft fibroma, and hyperkeratosis of the nipple and areola. There were 77 (29.6%) patients with inconsistency between the clinical impressions and pathological diagnoses. AN was the most clinically misdiagnosed condition, most commonly presumed to be PD or eczema. Conclusion: Eczema and PD are the most common biopsied NAC skin diseases. Late onset, unilateral involvement, and predilection for the nipple are several characteristics of PD, which are different from eczema. NAC skin diseases are easily misdiagnosed clinically, especially AN.

Progress of metabolomics in atopic dermatitis: a systematic review.

Atopic dermatitis (AD), a chronic inflammatory skin disorder characterized by recurrent eczema and intense pruritus, is a major skin-related burden worldwide. The diagnosis and treatment of AD is often challenging due to the high heterogeneity of AD, and its exact etiology is unknown. Metabolomics offers the opportunity to follow continuous physiological and pathological changes in individuals, which allows accurate diagnosis and management as well as providing deep insights into the etiopathogenesis of AD. Several metabolomic studies of AD have been published over the past few years. The aim of this review is to summarize these findings and help researchers to understand the rapid development of metabolomics for AD. A comprehensive and systematic search was performed using the PubMed, Embase, Cochrane Library and Web of Science databases. Twenty-six papers were finally included in the review after quality assessment. Significant differences in metabolite profiles were found between patients with AD and healthy individuals. This study provides a comprehensive overview of metabolomic research in AD. A better understanding of the metabolomics of AD may offer novel diagnostic, prognostic, and therapeutic approaches.

Clinical epidemiology and disease burden of bronchiolitis in hospitalized children in China: a national cross-sectional study.

BACKGROUND: Bronchiolitis is a common acute lower respiratory tract infection (ALRTI) and the most frequent cause of hospitalization of infants and young children with ALRTI. Respiratory syncytial virus is the main pathogen that leads to severe bronchiolitis. The disease burden is relatively high. To date, few descriptions of the clinical epidemiology and disease burden of children hospitalized for bronchiolitis are available. This study reports the general clinical epidemiological characteristics and disease burden of bronchiolitis in hospitalized children in China. METHODS: This study included the face sheet of discharge medical records collected from 27 tertiary children's hospitals from January 2016 to December 2020 that were aggregated into the FUTang Update medical REcords (FUTURE) database. The sociodemographic variables, length of stay (LOS) and disease burden of children with bronchiolitis were analyzed and compared using appropriate statistical tests. RESULTS: In total, 42,928 children aged 0-3 years were hospitalized due to bronchiolitis from January 2016 to December 2020, accounting for 1.5% of the total number of hospitalized children of the same age in the database during the period and 5.31% of the hospitalizations for ALRTI. The male to female ratio was 2.01:1. Meanwhile, more boys than girls were observed in different regions, age groups, years, and residences. The 1-2 year age group had the greatest number of hospitalizations for bronchiolitis, while the 29 days-6 months group had the largest proportion of the total inpatients and inpatients with ALRTI in the same age group. In terms of region, the hospitalization rate of bronchiolitis was the highest in East China. Overall, the number of hospitalizations from 2017 to 2020 showed a decreasing trend from that in 2016. Seasonally, the peak hospitalizations for bronchiolitis occurred in winter. Hospitalization rates in North China in autumn and winter were higher than those in South China, while hospitalization rates in South China were higher in spring and summer. Approximately, half of the patients with bronchiolitis had no complications. Among the complications, myocardial injury, abnormal liver function and diarrhea were more common. The median LOS was 6 days [interquartile range (IQR) = 5-8], and the median hospitalization cost was 758 United States dollars (IQR = 601.96-1029.53). CONCLUSIONS: Bronchiolitis is a common respiratory disease in infants and young children in China, and it accounts for a higher proportion of both total hospitalizations and hospitalizations due to ALRTI in children. Among them, children aged 29 days-2 years are the main hospitalized population, and the hospitalization rate of boys is significantly higher than that of girls. The peak season for bronchiolitis is winter. Bronchiolitis causes few complications and has a low mortality rate, but the burden of this disease is heavy.

Epidemiology and Disease Burden of Hospitalized Children With Viral Central Nervous System Infections in China, 2016 to 2020.

BACKGROUND: Viral central nervous system (CNS) infections seriously threaten the life and health of children, with a high mortality and severe sequelae in China and globally. Surveillance of viral CNS infections in children is important, especially in hospitalized children, to facilitate disease evaluation. METHODS: In this study, we collected the data on the discharged Face Sheet of Medical Records from database from 2016 to 2020 and analyzed the epidemiologic characteristics and disease burden of hospitalized children (≤18 years old) with viral CNS infections in China. We classified the discharge diagnosis of viral CNS infection as viral encephalitis (VE), viral meningitis (VM), viral meningoencephalitis (VME), viral encephalomyelitis (VEM), and viral meningomyelitis (VMM). RESULTS: A total of 42,641 cases of viral CNS infections were included in the database, consisting of 39,279 cases with VE (92.47%), 2011 cases with VM (4.73%), 1189 cases with VME (2.80%), 118 cases with VEM (0.28%), and 44 cases with VMM (0.10%). The number of hospitalized patients with viral CNS infections accounted for 0.74% (42,641 of 5,790,910) of all hospitalized cases. The onset of viral CNS infections presented seasonal characteristic, with peaks in June to July and December to January. Seizures are the most frequent complication of this disorder. Median length of stay and inpatient expenditures for patients with viral CNS infections were 9 days and 1144.36 USD. Causative viruses were identified in 4.33% (1848 of 42,641) of patients. CONCLUSIONS: This study will help understand the clinical epidemiology and disease burden of hospitalized children with viral CNS infections in China.

The top 100 most cited articles in the last two decades of atopic dermatitis: A bibliometric analysis.

Background: Atopic dermatitis (AD) is the leading cause of skin-related disease burden worldwide, affecting a large percentage of the population. Bibliometrics is the statistical analysis of academic literature in a certain field. Objectives: We aimed to perform the latest bibliometric analysis of atopic dermatitis literature. Methods: We searched the Web of Science database on 29th Nov 2021. We used the keywords "atopic dermatitis," "atopic eczema," and "eczema" for our search. All items published between 2001 and 2021 were included. The top 100 most cited articles were identified and analyzed. Results: Our study provided a detailed bibliometric analysis of the top 100 most cited articles on atopic dermatitis. These articles were published between 2002 and 2019 and were from 15 different countries, mostly in the USA and Germany. Most articles have focused on the pathogenesis and treatment of AD. The Journal of Allergy and Clinical Immunology made the greatest contribution to the top 100 list, with 28 articles. The most cited article originated from Lancet. The highest number of citations was seen in 2006, with 9220 citations, while the highest number of publications was seen in 2006 with 12 publications. Conclusions: Our study aims to provide physicians and researchers with a historical perspective for the scientific progress of atopic dermatitis, and help clinicians effectively obtain useful articles that have a significant impact on the field of atopic dermatitis.
