Reference values for exhaled nitric oxide in healthy children aged 6-18 years in China: a cross-sectional, multicenter clinical study.

Background: The reference values of eNO have certain differences among people of different countries and races. We aimed to obtain the reference value of eNO in healthy children and adolescents (6-18 years old) in China and to explore the associations between the reference values with ages, gender, heights, BMI, and regions.

Methods: We measured FeNO levels in 5949 healthy Chinese children and adolescents, FeNO and CaNO levels in 658 participants from 16 provinces of 7 administrative areas in China aged 6-18.

Hip Instability in Children With Spinal Muscular Atrophy: A Retrospective Study.

Purpose: Hip subluxation and dislocation are known problems for children with spinal muscular atrophy (SMA). Medical complexity of these children typically results in absence of monitoring and intervention for pathologic hips. Patterns of hip migration and acetabular morphology in SMA have not been described.

Pediatric onset neuronal ceroid lipofuscinoses: Unraveling clinical and genetic specifications.

Objective: To unravel the clinical and genetic specifications of Neuronal ceroid lipofuscinosis (NCL).

Methods: This is a retrospective cross-sectional study conducted in the Department of Pediatric Neurology Children Hospital and University of Child Health Sciences, Lahore, Pakistan from March 2017 to March 2022. The primary outcome was to measure genotype-phenotype correlation by segregation of phenotypes according to genotype.

Clinical and epidemiological profiles of pediatric COVID-19 in two private Kenyan hospitals.

Introduction: COVID-19 infection has attracted global attention with limited published data on the burden in African children.

Methods: hospital-based longitudinal survey in children with COVID-19 infection, aged 0-18 years admitted between August 2020 and December 2021. The main objective of the study was to describe socio-demographic, clinical and diagnostic manifestations of COVID-19 infection in children.

CAMK2G Promotes Neuronal Differentiation and Inhibits Migration in Neuroblastoma.

Purpose: Neuroblastoma (NB) originates from differentiation arrest of sympathoadrenal progenitors in the neural crest. It is necessary to reveal the differentiation mechanism of NB. Previously, we reported that Purkinje cell protein 4 (PCP4) is a well-differentiated marker of NB tissues.

Reliability of self-reported pubertal development scale for girls in early adolescent: a school population-based study.

Objectives: The study aimed to evaluate the correlation between self-reported pubertal developmental scale (PDS) and physically assessed Tanner staging by an experienced pediatrician among girls.

Methods: In a school population-based study in Zhongshan, China, we recruited 1,722 girls in grades 1-3 by a multistage stratified cluster random sampling method. Participants completed self-reported PDS questionnaire prior to physical examination.

Individuals carrying the HLA-B*15 allele exhibit favorable responses to COVID-19 vaccines but are more susceptible to Omicron BA.5.2 and XBB.1.16 infection.

Background: Natural infection or vaccination have provided robust immune defense against SARS-CoV-2 invasion, nevertheless, Omicron variants still successfully cause breakthrough infection, and the underlying mechanisms are poorly understood.

Methods: Sequential blood samples were continuously collected at different time points from 252 volunteers who were received the CanSino Ad5-nCoV (n= 183) vaccine or the Sinovac CoronaVac inactivated vaccine (n= 69). The anti-SARS-CoV-2 prototype and Omicron BA.

Development of a prognostic nomogram for esophageal squamous cell carcinoma patients received radiotherapy based on clinical risk factors.

Purpose: The goal of the study was to create a nomogram based on clinical risk factors to forecast the rate of locoregional recurrence-free survival (LRFS) in patients with esophageal squamous cell carcinoma (ESCC) who underwent radiotherapy (RT).

Methods: In this study, 574 ESCC patients were selected as participants. Following radiotherapy, subjects were divided into training and validation groups at a 7:3 ratio.

Disease burden comparison and associated risk factors of early- and late-onset neonatal sepsis in China and the USA, 1990-2019.

Background: The morbidity and mortality rates of neonatal sepsis are high, with significant differences in risk factors and disease burden observed between developing and developed countries.

Objective: To provide evidence to support recommendations on improving public health policies using a comparative systematic analysis of the disease burden.

Methods: Using data from the Global Burden of Disease Study 2019, the prevalence and incidence of early- and late-onset neonatal sepsis and the disability-adjusted life years (DALYs) due to both countries in both China and the United States of America (USA) were assessed.

Inspiratory muscle training in children with neuromuscular disorders.

Background: Progressive respiratory muscle weakness and ineffective cough contribute to morbidity and mortality in children with neuromuscular disorders (NMD). Inspiratory muscle training (IMT) aims to preserve or improve respiratory muscle strength and reduce respiratory morbidity. This study aimed to determine the safety and efficacy of IMT in children with NMD.

Trisomy 8 presentation by inflammatory manifestations and its response to thalidomide: two case reports and narrative review.

Objective: It has been recognized that there is a nexus among Trisomy 8 (T8), Behcet's disease (BD), and myelodysplastic syndrome (MDS). We reported a series of inflammatory features in 2 children with T8 without hematological involvement.

Methods: 2 children with trisomy 8 who were excluded from MDS were retrospectively collected from the Department of Rheumatology and Immunology, Children's Hospital of Nanjing Medical University, Nanjing.

Phosphorylation of the DNA damage repair factor 53BP1 by ATM kinase controls neurodevelopmental programs in cortical brain organoids.

53BP1 is a well-established DNA damage repair factor that has recently emerged to critically regulate gene expression for tumor suppression and neural development. However, its precise function and regulatory mechanisms remain unclear. Here, we showed that phosphorylation of 53BP1 at serine 25 by ATM is required for neural progenitor cell proliferation and neuronal differentiation in cortical brain organoids.

SHP2 ablation mitigates osteoarthritic cartilage degeneration by promoting chondrocyte anabolism through SOX9.

Articular cartilage phenotypic homeostasis is crucial for life-long joint function, but the underlying cellular and molecular mechanisms governing chondrocyte stability remain poorly understood. Here, we show that the protein tyrosine phosphatase SHP2 is differentially expressed in articular cartilage (AC) and growth plate cartilage (GPC) and that it negatively regulates cell proliferation and cartilage phenotypic program. Postnatal SHP2 deletion in Prg4 AC chondrocytes increased articular cellularity and thickness, whereas SHP2 deletion in Acan pan-chondrocytes caused excessive GPC chondrocyte proliferation and led to joint malformation post-puberty.

Risk factors, prevention and treatment of weight gain associated with the use of antidepressants and antipsychotics: a state-of-the-art clinical review.

Introduction: People with severe mental illness have poor cardiometabolic health. Commonly used antidepressants and antipsychotics frequently lead to weight gain, which may further contribute to adverse cardiovascular outcomes.

Areas Covered: We searched MEDLINE up to April 2023 for umbrella reviews, (network-)meta-analyses, trials and cohort studies on risk factors, prevention and treatment strategies of weight gain associated with antidepressants/antipsychotics.
