Exertional desaturation (ED) is common and is associated with poorer clinical outcomes in chronic obstructive pulmonary disease (COPD). The age, dyspnea, airflow obstruction (ADO) and body mass index, airflow obstruction, dyspnea, and exercise (BODE) indexes are used to predict the prognosis of COPD patients. This study aimed to investigate the relationship between these indexes, pulmonary function, medical costs, and ED in COPD patients. Data were collected from the electronic database of the Kaohsiung Chang Gung Memorial Hospital. This retrospective study included 396 patients categorized as either ED = 231) or non-ED ( = 165). Variables (including age, smoking history, body mass index (BMI), pulmonary function test, maximum inspiratory pressure (MIP) and maximum expiratory pressure (MEP), six minutes walking test distance (6MWD), SpO, COPD Assessment Test (CAT) score, ADO index, BODE index, Charlson comorbidity index (CCI), and medical costs) were compared between the two groups, and their correlations were assessed. ED was defined as SpO less than 90% or SpO decrease of more than 4% compared to baseline levels during 6MWT. A significant statistical difference was found regarding a lower score of the ADO index and the BODE index (both < 0.001), better pulmonary function (forced expiratory volume in the first second (FEV1), < 0.001; FEV1/ forced vital capacity (FVC), < 0.001; diffusion capacity of the lung for carbon monoxide (DLCO), < 0.001), and higher minimal oxygen saturation ( < 0.001) in non-ED COPD patients. No difference was found in the distance of the 6MWT ( = 0.825) and respiratory muscle strength (MIP; MEP, = 0.86; 0.751). However, the adjusted multivariate logistic regression analysis showed that only SpO (minimal) had a significant difference between of the ED and non-ED group ( < 0.001). There was either no difference in the medical expenses between ED and non-ED COPD patients. SpO (minimal) during the 6MWT is the independent factor for ED. ED is related to BODE and ADO indices, but is not related to medical expense.

We sought to characterize cellular composition across the cardiovascular system of the healthy Wistar rat, an important model in preclinical cardiovascular research. We performed single-nucleus RNA sequencing (snRNA-seq) in 78 samples in 10 distinct regions, including the four chambers of the heart, ventricular septum, sinoatrial node, atrioventricular node, aorta, pulmonary artery, and pulmonary veins, which produced 505,835 nuclei. We identified 26 distinct cell types and additional subtypes, with different cellular composition across cardiac regions and tissue-specific transcription for each cell type.

Introduction: Cystic fibrosis (CF) is an autosomal recessive disorder caused by mutations in the CF transmembrane regulator (CFTR) gene, leading to progressive lung disease and systemic complications. Lung disease remains the primary cause of morbidity and mortality, making early detection of lung function decline crucial. The Lung Clearance Index (LCI), derived from the multiple breath washout (MBW) test, has emerged as a sensitive measure for identifying early airway disease.

Purpose: Few investigational reports have evaluated the status of cardiovascular manifestations of coronavirus disease 2019 (COVID-19) during the Omicron dominance period. In this study, we aimed to investigate the cardiac function parameters and clinical outcomes of patients with COVID-19 before and after the Omicron variant (OV) propagation.
Methods: We retrospectively analyzed the data of 88 adult patients with COVID-19 who underwent clinically indicated standard transthoracic echocardiography (TTE) in intensive care wards.

Background: The combination of immunotherapy and chemotherapy has demonstrated an enhancement in progression-free survival (PFS) for individuals with advanced and metastatic triple-negative breast cancer (TNBC) when compared to the use of chemotherapy alone. Nevertheless, the extent to which different subgroups of metastatic TNBC patients experience this benefit remains uncertain.
Objectives: Our objective was to conduct subgroup analyses to more precisely identify the factors influencing these outcomes.

Background: This study aims to develop Z-Score models to normalize measurements of three coronary arteries and enhance the diagnosis of Kawasaki disease (KD) in children from newborns to 10 years old. Developing a reliable Z-Score model is challenging, as some existing models fail the normality test. Overcoming these challenges is crucial for improving KD diagnosis.
