Picornavirus replication is known to cause extensive remodelling of Golgi and endoplasmic reticulum membranes and a number of the host proteins involved in the viral replication complex have been identified, including oxysterol binding protein (OSBP) and phosphatidylinositol 4-kinase III beta (PI4KB). Since both OSBP and PI4KB are substrates for protein kinase D (PKD) and PKD is known to be involved in the control of Golgi vesicular and lipid transport, we hypothesised that PKD played a role in viral replication...

BACKGROUND: Long-acting bronchodilator monotherapy (long-acting β2-agonist [LABA] or long-acting muscarinic antagonist [LAMA]) is extensively used for treatment of patients with chronic obstructive pulmonary disease (COPD) with mild-to-moderate airflow limitation. However, a substantial number of patients remain symptomatic despite treatment with a single bronchodilator, necessitating a change in therapy. METHODS: This 12-week, randomized, multicenter, open-label, phase IV study aims to show that the once-daily indacaterol/glycopyrronium (IND/GLY) 110/50 μg fixed-dose LABA/LAMA combination results in an improved lung function in symptomatic patients with mild-to-moderate COPD who switch from once-daily tiotropium 18 μg...

Continuous monitoring of blood oxygen saturation (SpO2) level and heart rate is critical in surgery, ICUs and patients suffering from Chronic Obstructive Pulmonary Diseases. Pulse oximeters which compute SpO2 using transmittance photoplethysmography (PPG), is widely accepted for continuous monitoring. Presence of motion artifacts in PPG signals is a major obstacle in the extraction of reliable cardiovascular parameters, in real time and continuous monitoring applications. In this paper, a wrist worn device with a custom finger probe with an integrated accelerometer to remove motion artifacts is presented...

The global inhomogeneity (GI) index is a electrical impedance tomography (EIT) parameter that quantifies the tidal volume distribution within the lung. In this work the global inhomogeneity index was computed for twenty subjects in order to evaluate his potential use in the detection and follow up of chronic obstructive pulmonary disease (COPD) patients. EIT data of 17 subjects were acquired: 14 patients with the main diagnoses of COPD and 3 healthy subjects which served as a control group. Two or three datasets of around 30 seconds were acquired at 33 scans/s and analysed for each subject...

Chronic Obstructive Pulmonary Disease (COPD) and asthma each represent a large proportion of the global disease burden; COPD is the third leading cause of death worldwide and asthma is one of the most prevalent chronic diseases, afflicting over 300 million people. Much of this burden is concentrated in the developing world, where patients lack access to physicians trained in the diagnosis of pulmonary disease. As a result, these patients experience high rates of underdiagnosis and misdiagnosis. To address this need, we present a mobile platform capable of screening for Asthma and COPD...

The automatic detection of adventitious lung sounds is a valuable tool to monitor respiratory diseases like chronic obstructive pulmonary disease. Crackles are adventitious and explosive respiratory sounds that are usually associated with the inflammation or infection of the small bronchi, bronchioles and alveoli. In this study a multi-feature approach is proposed for the detection of events, in the frame space, that contain one or more crackles. The performance of thirty-five features was tested. These features include thirty-one features usually used in the context of Music Information Retrieval, a wavelet based feature as well as the Teager energy and the entropy...

Traditionally, measurements of the oxygen saturation (SpO2) has been confound to the extremities. In this study, we therefore investigated the possibility for reliable estimation of clinically relevant SpO2 levels from photoplethysmography (PPG) obtained on the sternum of patients with obstructive airway diseases. We initiated the study with a calibration of a prototype sternal PPG sensor. In accordance with the ISO 80601-2-61:2011 guidelines, the calibration was conducted as a controlled desaturation study...

Automated texture analysis of lung computed tomography (CT) images is a critical tool in subtyping pulmonary emphysema and diagnosing chronic obstructive pulmonary disease (COPD). Texton-based methods encode lung textures with nearest-texton frequency histograms, and have achieved high performance for supervised classification of emphysema subtypes from annotated lung CT images. In this work, we first explore characterizing lung textures with sparse decomposition from texton dictionaries, using different regularization strategies, and then extend the sparsity-inducing constraint to the construction of the dictionaries...

INTRODUCTION: Several dual bronchodilator fixed dose inhaler medications were recently approved for the treatment of chronic obstructive pulmonary disease (COPD). These products combine a long-acting beta2 -agonist (LABA) and long-acting muscarinic antagonist (LAMA). In clinical trials, the separate mechanisms of the bronchodilators resulted in improved lung function. COPD treatment guidelines currently recommend combination LABA/LAMA as alternative therapy to combination LABA/ inhaled corticosteroid (ICS)...

Nonmedical use of opioid medications constitutes a serious health threat as the rates of addiction, overdoses, and deaths have risen in recent years. Increasingly, inappropriate and excessively liberal prescribing of opioids by physicians is understood to be a central part of the crisis. Public health officials, hospital systems, and legislators are developing programs and regulations to address the problem in sustained and systematic ways that both insures effective treatment of pain and appropriate limits on the availability of opioids...

OBJECTIVE: Previous studies have reported that depression may play a crucial role in the occurrence of vertebral fractures. However, a clear correlation between depressive disorders and osteoporotic fractures has not been established. We explored the association between depressive disorders and subsequent new-onset vertebral fractures. Additionally, we aimed to identify the potential risk factors for vertebral fracture in patients with a depressive disorder. METHODS: We studied patients listed in the Taiwan National Health Insurance Research Database who were diagnosed with a depressive disorder by a psychiatrist...

PURPOSE: Patients with chronic obstructive pulmonary disease (COPD) have body balance deficits, with consequent fall risk. It is possible that body sway in patients with COPD affects their ability to perform daily activities. The purpose of this study was to determine whether body balance is similar in patients with COPD and healthy persons when performing static and dynamic activities. In addition, we wanted to assess whether impairment of balance is related to the presence of falls in patients with COPD...
