Celeste Porsbjerg, Andrew Menzies-Gow
Patients with severe asthma represent a minority of the total asthma population, but carry a majority of the morbidity and healthcare costs. Achieving better asthma control in this group of patients is therefore of key importance. Systematic assessment of patients with possible severe asthma to identify treatment barriers and triggers of asthma symptoms, including co-morbidities, improves asthma control and reduces healthcare costs and is recommended by international guidelines on management of severe asthma...

BACKGROUND: The aetiology and origin of gastrointestinal symptoms in Parkinson's disease (PD) remains poorly understood. Gastroparesis, small bowel transit delay and bacterial overgrowth may, individually or collectively, play a role. AIMS: In patients with PD and functional gastrointestinal symptoms, we aimed to determine the utility of the wireless motility capsule and lactulose breath tests in further defining their symptoms' aetiology. METHODS: In this retrospective cohort study, consecutive patients with PD and functional gastrointestinal symptoms underwent clinical assessment, as well as wireless motility capsule and lactulose breath testing using standard protocols...

BACKGROUND: Numerous experiments in rodents suggest a causative link between exposure to general anaesthetics during brain growth spurt and poor long-lasting neurological outcomes. Many of these studies have been questioned with regard of their translational value, mainly because of extremely long anaesthesia exposure. Therefore, the aim of the present study was to assess the impact of a short sevoflurane anaesthesia, alone or combined with clonidine treatment, on respiratory function in spontaneously breathing rat pups and overall effects on long-lasting emotional and cognitive functions...

Dysfunctional breathing is common and represents important differential diagnoses for respiratory discomfort. Typical examples include habit cough, sighing dyspnoea, hyperventilation syndrome, dysfunctional breathing patterns or vocal cord dysfunction (1,2). Comorbidities are frequent, especially with bronchial asthma. In some cases dysfunctional breathing may be a sequelae of child neglect or abuse. This article is protected by copyright.

Chronic Obstructive Pulmonary Disease (COPD) is mainly caused by smoking and presents with shortness of breath that is progressive and irreversible. It is a worldwide health problem and the fourth most common cause of chronic disability and mortality (even in developed countries). It is a complex disease involving both the airway and lung parenchyma. Small-airway fibrosis is the main contributor to physiological airway dysfunction in COPD. One potential mechanism contributing to small-airway fibrosis is epithelial mesenchymal transition (EMT)...

Spinal cord injury (SCI) is characterised by profound respiratory compromise secondary to the level of loss of motor, sensory and autonomic control associated with the injury. This review aims to detail these anatomical and physiological changes after SCI, and outline their impact on respiratory function. Injury-related impairments in strength substantially alter pulmonary mechanics, which in turn affect respiratory management and care. Options for treatments must therefore be considered in light of these limitations...

Obstructive Sleep Apnea (OSA) is a form of respiratory dysfunction that affects 20% of adults in the world. Among the first-line treatments that are used to mitigate the effects of OSA are continuous positive airway pressure (CPAP) and mandibular repositioning devices (MRD). Although CPAP provides a more efficacious therapy than MRDs, recent studies suggest that both are comparable in overall effectiveness due to greater patient preference and adherence to MRD therapy. In this paper, we present the Auto-Positioner, a novel add-on for MRDs that adjusts the extent to which the mandible (lower jaw) is advanced in response to respiratory signals indicating labored breathing during sleep, and to changes in sleeping position known to affect individual patient's airway patency...

BACKGROUND AND AIM: Diastolic wall strain (DWS) has been proposed as a simple noninvasive measure of left ventricular (LV) stiffness. This study investigated DWS as a possible predictor of mortality in severe aortic stenosis (AS). METHODS: 138 patients with severe AS (indexed aortic valve area [AVA]<0.6 cm(2) /m(2) ) and normal ejection fraction (>55%) were included. 52 patients (38%) had aortic valve interventions or poor image quality (n=5) and were excluded leaving 86 in the study group (84±8 years, 70% female, 69% African American)...

BACKGROUND: Endothelin receptor antagonists (ERA) have been recognised as effective therapy for pulmonary arterial hypertension in congenital heart disease (CHD-PH), and Eisenmenger syndrome (ES) since the Breathe 5 study. A new dual receptor antagonist - Macitentan - is currently undergoing trials to determine its efficacy in simple ES. To date there is little information on this therapy in CHD and we report our first experience, some with more complex diseases. METHODS: Data was collected prospectively from September 2014...

Acid sphingomyelinase deficiency (ASMD), a rare lysosomal storage disease, is an autosomal recessive genetic disorder caused by different SMPD1 mutations. Historically, ASMD has been classified as Niemann-Pick disease (NPD) types A (NPD A) and B (NPD B). NPD A is associated with a uniformly devastating disease course, with rapidly progressing psychomotor degeneration, leading to death typically by the age of 3 years, most often from respiratory failure. In contrast, the clinical phenotype and life expectancy of patients with NPD B may vary widely...
