Background: Chronic Obstructive Pulmonary Disease (COPD) is a heterogeneous condition with different risk factors, including family history. This study aimed to explore association between a family history of chronic airway disease and features and outcomes of COPD.
Methods: Participants were obtained from the RealDTC study between December 2016 and December 2022.
Background: The influenza vaccination rate of chronic obstructive pulmonary disease (COPD) patients in China was very low. In this study, we aimed to evaluate the effect of clinician-led intensive health education on influenza vaccination in outpatients with COPD and the effect of influenza vaccination on the risk of acute exacerbations in the real world.
Methods: Participants were from the Real World Research of Diagnosis and Treatment of COPD study, a real-world prospective cohort study.
Background: The Global Initiative for Chronic Obstructive Lung Disease (GOLD) 2023 revised the combined chronic obstructive pulmonary disease (COPD) assessment, merging groups C and D into group E, and revised the initial inhalation therapy recommendation. We aimed to evaluate the treatment responses among different inhalation therapies in GOLD group E patients stratified by the COPD assessment test (CAT) scores and forced expiratory volume in one-second percentage of predicted (FEV1%pred).
Methods: In this retrospective cohort study, we included patients with COPD registered in the Real World Research of Diagnosis and Treatment of COPD (RealDTC) study between January 2017 and June 2023.
Background: Bone marrow mesenchymal stem cells (BMSCs)-derived exosomes are rich in a variety of active substances, including microRNA (miR) and have shown powerful therapeutic effects to ameliorate cell injury and diseases. However, the role of BMSCs-derived exosomes on chronic obstructive pulmonary disease (COPD) has been poorly studied. In addition, pulmonary microvascular endothelial cells (PMVECs) apoptosis contributes to the onset of COPD.

This condition carries a high risk of mortality and severe neurological sequelae, such as cognitive impairment and epilepsy. Pain, a central feature of meningitis, results from the activation of nociceptor sensory neurons by inflammatory mediators or bacterial toxins.

Transcriptomics is a highly effective tool for the development of novel anti-tuberculosis drugs. However, most studies focus only on changes in gene expression levels at specific time points.

View Article and Find Full Text PDFMycobacterium tuberculosis (Mtb) is an intracellular pathogen capable of adapting and surviving within macrophages, utilizing host nutrients for its growth and replication. Cholesterol is the main carbon source during the infection process of Mtb. Cholesterol metabolism in macrophages is tightly associated with cell functions such as phagocytosis of pathogens, antigen presentation, inflammatory responses, and tissue repair.

Multiple evanescent white dot syndrome (MEWDS) following COVID-19 vaccination is a rare adverse reaction associated with COVID-19 vaccines. In this systematic review, we collected 19 articles with 27 patients up to November 1, 2023, summarizing the basic information, clinical manifestations, examinations, treatments, and recoveries of the 27 patients.

There is no nomogram model available for mortality prediction of stable COPD. We intended to develop and validate a nomogram model to predict mortality risk in stable COPD patients for personalised prognostic assessment.
View Article and Find Full Text PDFThe central nervous system (CNS) harbors its own special immune system composed of microglia in the parenchyma, CNS-associated macrophages (CAMs), dendritic cells, monocytes, and the barrier systems within the brain. Recently, advances in the immune cells in the CNS provided new insights to understand the development of tuberculous meningitis (TBM), which is the predominant form of () infection in the CNS and accompanied with high mortality and disability. The development of the CNS requires the protection of immune cells, including macrophages and microglia, during embryogenesis to ensure the accurate development of the CNS and immune response following pathogenic invasion.

Objectives: This study aimed to analyze the future exacerbation and mortality of different inhalation therapies among patients with chronic obstructive pulmonary disease (COPD) in various groups based on the GOLD 2017 and GOLD 2023 reports.
Design: This is a multicenter and retrospective study.
Background: The revised Global Initiative for Chronic Obstructive Lung Disease (GOLD) 2023 group ABE classification has undergone major modifications, which can simplify clinical assessment and optimize treatment recommendations for Chronic Obstructive Pulmonary Disease (COPD). However, the predictive value of the new grouping classification for prognosis is worth further exploration. We aimed to compare the prediction of hospitalization and mortality between this new GOLD group 2023 ABE classification and the earlier 2017 ABCD classification in a Chinese COPD cohort.

Background: We analyzed the clinical characteristics and outcomes in non-frequent exacerbation patients with chronic obstructive pulmonary disease (COPD).
Methods: In this retrospective cohort study, we enrolled patients with stable COPD from 12 hospitals. Non-frequent exacerbation was defined as less than two times of exacerbations in the past year.
This study aimed to analyze the clinical characteristics and treatment response of patients with chronic obstructive pulmonary disease (COPD) with low body mass index (BMI). In this cross-sectional study, we enrolled patients with stable COPD from the database setup by the Second Xiangya Hospital of Central South University. We classified the patients into three groups based on BMI: low-BMI (<18.

This was a multicenter, prospective observational study. Patients with COPD from ten hospitals in Hunan and Guangxi provinces in China were recruited from 1 January 2020 to 31 November 2021 for the study and were followed up for one year.

Methods: This was a prospective study. Patients with COPD were recruited into the study and followed up for one year.
Background: The Global Initiative for Chronic Obstructive Lung Disease (GOLD) document suggests that patients with chronic obstructive pulmonary disease (COPD) should be divided into a less symptomatic group. Moreover, single-inhaled drugs are recommended as initial inhalation therapy for them. However, many less symptomatic patients are provided double or triple-inhaled drugs as initial therapy in the real world.
