Automatic Emphysema Detection using Weakly Labeled HRCT Lung Images [PDF]

, 2017
A method for automatically quantifying emphysema regions using High-Resolution Computed Tomography (HRCT) scans of patients with chronic obstructive pulmonary disease (COPD) that does not require manually annotated scans for training is presented. HRCT scans of controls and of COPD patients with diverse disease severity are acquired at two different ...

Clinical predictors of lung function in patients recovering from mild COVID-19

BMC Pulmonary Medicine, 2022
Background Few studies have assessed lung function in Hispanic subjects recovering from mild COVID-19. Therefore, we examined the prevalence of impaired pulmonary diffusing capacity for carbon monoxide (DLCO) as defined by values below the lower limit of

Value of lung diffusing capacity for nitric oxide in systemic sclerosis

Physiological Reports, 2019
A decreased lung diffusing capacity for carbon monoxide (DLCO) in systemic sclerosis (SSc) is considered to reflect losses of alveolar membrane diffusive conductance for CO (DMCO), due to interstitial lung disease, and/or pulmonary capillary blood volume

Diffusing Capacity for Carbon Monoxide Predicts Response to Balloon Pulmonary Angioplasty in Patients With Inoperable Chronic Thromboembolic Pulmonary Hypertension

Frontiers in Cardiovascular Medicine, 2021
Background: The hemodynamic results of balloon pulmonary angioplasty vary among patients with inoperable chronic thromboembolic pulmonary hypertension (CTEPH). Previous studies revealed that microvasculopathy accounted for residual pulmonary hypertension

ADAR1‐HNRNPL‐Mediated CircCANX Decline Promotes Autophagy in Chronic Obstructive Pulmonary Disease

Advanced Science, EarlyView.
ADAR1‐HNRNPL interaction‐repressed circCANX recruits P53 mRNA and UPF1 to assemble a complex in nuclear. This complex promotes P53 mRNA degradation through the NMD pathway, and finally reduces autophagy and stress granules formation to further regulate inflammation.

Assessing the applicability of the new Global Lung Function Initiative reference values for the diffusing capacity of the lung for carbon monoxide in a large population set.

PLoS ONE, 2021
BackgroundThe single-breath diffusing capacity of the lung for carbon monoxide (DLCO) interpretation needs the comparison of measured values to reference values.

Semaphorin 3E–Plexin D1 Axis Drives Lung Fibrosis through ErbB2‐Mediated Fibroblast Activation

Advanced Science, EarlyView.
TGF‐β1 stimulation in fibroblasts leads to increased Furin expression, Furin‐mediated cleavage of P87‐Sema3E to P61‐Sema3E, which affects fibroblast function through the autocrine pathway, and the P61‐Sema3E‐PlexinD1 axis promotes fibroblast activation, proliferation and migration by affecting ErbB2 phosphorylation, which in turn activates the ErbB2 ...

Progress in research on osteoporosis secondary to SARS‐CoV‐2 infection

Animal Models and Experimental Medicine, EarlyView.
This review explores the potential mechanisms, complications, risk factors, and future research directions related to osteoporosis secondary to SARS‐CoV‐2 infection. Key mechanisms include an imbalance between osteoclast and osteoblast activity driven by direct viral effects on bone, inflammation, hypoxia, dysregulation of noncoding RNAs, and metabolic

Autologous Nonmyeloablative Hematopoietic Stem Cell Transplantation for Diffuse Cutaneous Systemic Sclerosis: Identifying Disease Risk Factors for Toxicity and Long‐Term Outcomes in a Prospective, Single‐Arm Trial

Arthritis &Rheumatology, EarlyView.
Objective Two randomized trials for patients with diffuse systemic sclerosis (SSc) demonstrated an overall survival (OS) and event‐free survival (EFS) advantage of autologous hematopoietic stem cell transplantation (AHSCT) using CD34+ selected peripheral blood stem cells (PBSCs) compared with monthly cyclophosphamide (CY).

Comparison of diffusing capacity of carbon monoxide (DLCO) and total lung capacity (TLC) between Indigenous Australians and Australian Caucasian adults.

PLoS ONE, 2021
Background and objectiveCurrently there is paucity of evidence in the literature in relation to normative values for diffusing capacity of carbon monoxide (DLCO) and total lung capacity (TLC) among Indigenous Australians. Hence, in this study we assessed
