Long‐Term Follow‐up of Percutaneous Dilatational Tracheostomy in the Intensive Care Unit

The Laryngoscope, EarlyView.
By comparing percutaneous dilatational tracheostomy (PDT) in the intensive care unit (ICU) to the established baseline of surgical tracheostomy (ST) outside of the ICU, this study aimed to inform clinical practice guidelines and enhance the overall care of critically ill patients requiring tracheostomy interventions, with a particular focus on ...

Prevalence and Effects of Emphysema in Never-Smokers with Rheumatoid Arthritis Interstitial Lung Disease

EBioMedicine, 2018
Aims: Autoimmune conditions such as rheumatoid arthritis-related interstitial lung disease (RA-ILD) have been linked to the existence of emphysema in never-smokers. We aimed to quantify emphysema prevalence in RA-ILD never-smokers and investigate whether

Deep Learning from Label Proportions for Emphysema Quantification [PDF]

arXiv, 2018
We propose an end-to-end deep learning method that learns to estimate emphysema extent from proportions of the diseased tissue. These proportions were visually estimated by experts using a standard grading system, in which grades correspond to intervals (label example: 1-5% of diseased tissue).

Hybrid method for estimating lung ventilation from CT by combining intensity and motion information

Medical Physics, EarlyView.
Abstract Background Functional lung imaging modalities allow for capturing regional lung ventilation information. Computed Tomography based ventilation imaging (CTVI) has been proposed as a surrogate modality that relies on time‐resolved anatomical data and image processing. However, generating accurate ventilation maps using solely computed tomography

A formula for predicting emphysema extent in combined idiopathic pulmonary fibrosis and emphysema

Respiratory Research
Background No single pulmonary function test captures the functional effect of emphysema in idiopathic pulmonary fibrosis (IPF). Without experienced radiologists, other methods are needed to determine emphysema extent. Here, we report the development and

Pediatric Sharp Foreign Body Aspiration: Revealing Unexpected Risk Factors

Otolaryngology–Head and Neck Surgery, EarlyView.
Abstract Objective Characterize the demographic and clinical features of pediatric sharp foreign body aspiration (FBA). Study Design Twenty‐four‐year retrospective chart review. Setting Four tertiary‐care centers across four Canadian provinces. Methods A retrospective chart review was conducted on pediatric patients who underwent rigid bronchoscopy for

A tidal lung simulation to quantify lung heterogeneity with the Inspired Sinewave Test [PDF]

IEEE, EMBC2020, 2020
We have created a lung simulation to quantify lung heterogeneity from the results of the inspired sinewave test (IST). The IST is a lung function test that is non-invasive, non-ionising and does not require patients' cooperation. A tidal lung simulation is developed to assess this test and also a method is proposed to calculate lung heterogeneity from ...

Matrix Remodeling in Pulmonary Fibrosis and Emphysema.

American Journal of Respiratory Cell and Molecular Biology, 2016
Pulmonary fibrosis and emphysema are chronic lung diseases characterized by a progressive decline in lung function, resulting in significant morbidity and mortality.
