AZD5423 is a novel, inhaled, selective glucocorticoid receptor modulator (SGRM), which in an allergen challenge model in asthmatics improved lung function and airway hyper-reactivity. In the current trial, AZD5423 was for the first time tested in patients with chronic obstructive pulmonary disease (COPD). In this double-blind, randomised and parallel group study, we examined airway and systemic effects of two doses of AZD5423, inhaled via Turbuhaler for 12 weeks, in 353 symptomatic COPD patients (average pre-bronchodilator forced expiratory volume in one second (FEV1) at screening was 50-52% of predicted normal)...

Chronic Obstructive Pulmonary Disease is the third leading cause of death in the US, and is associated with periodic exacerbations, which account for the largest proportion of health care utilization, and lead to significant morbidity, mortality, and worsening lung function. A subset of patients with COPD have frequent exacerbations, occurring 2 or more times per year. Despite many interventions to reduce COPD exacerbations, there is a significant lack of knowledge in regards to their mechanisms and predisposing factors...

Neurodegeneration, the progressive death of neurons, loss of brain function, and cognitive decline is an increasing problem for senior populations. Its causes are poorly understood and therapies are largely ineffective. Neurons, with high energy and oxygen requirements, are especially vulnerable to detrimental factors, including age-related dysregulation of biochemical pathways caused by altered expression of multiple genes. GHK (glycyl-l-histidyl-l-lysine) is a human copper-binding peptide with biological actions that appear to counter aging-associated diseases and conditions...

REVIEW
Adam John Anthony McGuinness, Elizabeth Sapey
Markers of oxidative stress are increased in chronic obstructive pulmonary disease (COPD) and reactive oxygen species (ROS) are able to alter biological molecules, signaling pathways and antioxidant molecule function, many of which have been implicated in the pathogenesis of COPD. However, the involvement of ROS in the development and progression of COPD is not proven. Here, we discuss the sources of ROS, and the defences that have evolved to protect against their harmful effects. We address the role that ROS may have in the development and progression of COPD, as well as current therapeutic attempts at limiting the damage they cause...

: Telemedicine is a medical application of advanced technology to disease management. This modality may provide benefits also to patients with chronic obstructive pulmonary disease (COPD). Different devices and systems are used. The legal problems associated with telemedicine are still controversial. Economic advantages for healthcare systems, though potentially high, are still poorly investigated. A European Respiratory Society Task Force has defined indications, follow-up, equipment, facilities, legal and economic issues of tele-monitoring of COPD patients including those undergoing home mechanical ventilation...

INTRODUCTION: To promote adaptation to treatment with continuous positive airway pressure, an information document was developed for people starting their treatment with continuous positive airway pressure. METHODS: Seven patients with obstructive sleep apnea took part in a focus group. This allowed the identification both of useful information and the best way that this information could be presented. RESULTS: The key specific information objectives and the best emotional register to use were as follows: (1) develop awareness about the physiological mechanisms and consequences that can occur from obstructive sleep apnea syndrome, using formulations arousing fear, (2) enable the recognition of the symptoms, risk factors and chronicity of this syndrome, (3) reassure and motivate the patient about treatment with continuous positive airway pressure...

INTRODUCTION: Quality of life is adversely affected in Chronic Obstructive Pulmonary Disease (COPD), due to irreversible, progressive nature of the disease and limitations of current treatment options available. One of the important aim of treatment of COPD is to improve Quality of Life (QoL). Cigarette smoke contains numerous free radicals and other oxidants. Oxidative stress has been implicated in pathogenesis, progression of disease and exacerbation in COPD. Pulmonary tuberculosis, outdoor and indoor air pollution and many others are aetiologies of COPD in non-smokers...
