Methods: A two-center prospective study from 2020 to 2023 recruited infants (n=286) admitted to the respiratory departments of two children's hospitals in southwestern and southeastern China during RSV epidemic.

Relationship between platelet distribution width and non-dipping pattern in children with essential hypertension.

Background: Hypertension has shown a trend of prevalence at younger ages, and the non-dipping pattern is associated with target organ damage in hypertension. However, few studies have yet investigated the clinical characteristics and risk factors of non-dipper status in essential hypertension children. This study aimed to explore the clinical characteristics and possible indicators associated with non-dipper status in children with essential hypertension.

The role of IFN-γ/CXCL10 axis in Mycoplasma pneumonia infection.

Mycoplasma pneumoniae caused lower respiratory tract infection in children and can exacerbate these infections through the production of various inflammatory factors, with chemokines playing a key role. However, the pathogenesis of this infection is complicated and thus has not been thoroughly studied. We clarified that cytokine expression levels were analyzed in both peripheral blood and bronchoalveolar lavage fluid (BALF), and in vitro assays were conducted using THP-1 macrophages.

Intestine-Decipher Engineered Capsules Protect Against Sepsis-induced Intestinal Injury via Broad-spectrum Anti-inflammation and Parthanatos Inhibition.

Sepsis is a severe systemic inflammatory syndrome characterized by a dysregulated immune response to infection, often leading to high mortality rates. The intestine, owing to its distinct structure and physiological environment, plays a pivotal role in the pathophysiology of sepsis. It functions as the "central organ" or "engine" in the progression of sepsis, with intestinal injury exacerbating the condition.

Caregivers' experience of having a child with Down syndrome: a meta-synthesis.

Catalase-assembled nanoparticles for PA/CT dual-modality imaging and repair of acute alcoholic gastritis.

The development of simple, rapid, sensitive and noninvasive theranostic agents for acute gastritis is crucial. Herein, an engineering catalase-conjugated bismuth nanoparticle was fabricated for near-infrared photoacoustic imaging and computed tomography imaging of acute alcoholic gastritis. This nanoparticle could quickly respond to HO and H overexpressed in the microenvironment of acute gastritis in mice, emitting strong signals for precise localization.

[Clinical sub-phenotypes of acute kidney injury in children and their association with prognosis].

Objectives: To investigate the clinical sub-phenotype (SP) of pediatric acute kidney injury (AKI) and their association with clinical outcomes.

Methods: General status and initial values of laboratory markers within 24 hours after admission to the pediatric intensive care unit (PICU) were recorded for children with AKI in the derivation cohort (=650) and the validation cohort (=177). In the derivation cohort, a least absolute shrinkage and selection operator (LASSO) regression analysis was used to identify death-related indicators, and a two-step cluster analysis was employed to obtain the clinical SP of AKI.

Background: The aim of this study was to investigate the clinical characteristics of severe pneumonia caused by human bocavirus (HBoV) infection to explore the associated risk factors.

Methods: We conducted a retrospective review of data from children hospitalized with HBoV pneumonia. Based on the severity of pneumonia, patients were categorized into severe pneumonia and non-severe pneumonia groups.

NVP-2, in combination with Orlistat, represents a promising therapeutic strategy for acute myeloid leukemia.

Cell cycle dysregulation and the corresponding metabolic reprogramming play significant roles in tumor development and progression. CDK9, a kinase that regulates gene transcription and cell cycle, also induces oncogene transcription and abnormal cell cycle in AML cells. The function of CDK9 for gene regulation in AML cells requires further exploration.

Costs of Influenza Illness and Acute Respiratory Infections by Household Income Level: Catastrophic Health Expenditures and Implications for Health Equity.

Background: Seasonal influenza illness and acute respiratory infections can impose a substantial economic burden in low- and middle-income countries (LMICs). We assessed the cost of influenza illness and acute respiratory infections across household income strata.

Methods: We conducted a secondary analysis of data from a prior systematic review of costs of influenza and other respiratory illnesses in LMICs and contacted authors to obtain data on cost of illness (COI) for laboratory-confirmed influenza-like illness and acute respiratory infection.

Prognostic and therapeutic implications of measurable residual disease levels during remission induction of childhood ALL.

We evaluated the prognostic and therapeutic significance of measurable residual disease (MRD) during remission induction in pediatric acute lymphoblastic leukemia (ALL) patients. In the CCCG-ALL-2015 protocol, 7640 patients were categorized into low-, intermediate-, or high-risk groups based on clinical and genetic features. Final risk classification was determined by MRD assessed via flow cytometry on Days 19 and 46 of remission induction, with additional intensified chemotherapy for Day 19 MRD ≥1%.

USP5 inhibits anti-RNA viral innate immunity by deconjugating K48-linked unanchored and K63-linked anchored ubiquitin on IRF3.

Interferon regulatory factor 3 (IRF3) is a central hub transcription factor that controls host antiviral innate immunity. The expression and function of IRF3 are tightly regulated by the post-translational modifications. However, it is unknown whether unanchored ubiquitination and deubiquitination of IRF3 involve modulating antiviral innate immunity against RNA viruses.

Group 3 Innate Lymphoid Cells: A Potential Therapeutic Target for Steroid Resistant Asthma.

Asthma is a chronic airway inflammatory disease that affects millions globally. Although glucocorticoids are a mainstay of asthma treatment, a subset of patients show resistance to these therapies, resulting in poor disease control and increased morbidity. The complex mechanisms underlying steroid-resistant asthma (SRA) involve Th1 and Th17 lymphocyte activity, neutrophil recruitment, and NLRP3 inflammasome activation.

Diagnosis and treatment recommendations for glucose transporter 1 deficiency syndrome.

Background: Glucose transporter 1 deficiency syndrome (Glut1DS) was initially reported by De Vivo and colleagues in 1991. This disease arises from mutations in the SLC2A1 and presents with a broad clinical spectrum. It is a treatable neuro-metabolic condition, where prompt diagnosis and initiation of ketogenic dietary therapy can markedly enhance the prognosis.
