Use of time in chronic obstructive pulmonary disease: Longitudinal associations with symptoms and quality of life using a compositional analysis approach.

PLoS One 2019 21;14(3):e0214058. Epub 2019 Mar 21.

Alliance for Research in Exercise, Nutrition and Activity, School of Health Sciences, University of South Australia, Adelaide, South Australia, Australia.

Background And Objectives: This study explored whether, for people with chronic obstructive pulmonary disease (COPD), changes to the 24-hour composition of physical activity (PA), sedentary behaviour (SB) and sleep were associated with changes in symptoms and health-related quality of life (HRQoL); and how time re-allocations between these behaviours were associated with changes in outcomes.

Methods: This study pools data on people with COPD drawn from two previous studies: a randomised controlled trial of cognitive behavioural therapy and pulmonary rehabilitation and a usual care cohort. Participants recalled behaviours and completed symptom and HRQoL assessments at baseline (T0) and four months (T1). Read More

Subject2Vec: Generative-Discriminative Approach from a Set of Image Patches to a Vector.

Med Image Comput Comput Assist Interv 2018 Sep 26;11070:502-510. Epub 2018 Sep 26.

Computer Science Department, University of Pittsburgh, USA.

We propose an attention-based method that aggregates local image features to a subject-level representation for predicting disease severity. In contrast to classical deep learning that requires a fixed dimensional input, our method operates on a of image patches; hence it can accommodate variable length input image without image resizing. The model learns a clinically interpretable subject-level representation that is reflective of the disease severity. Read More

Standardising hospitalist practice in sepsis and COPD care.

BMJ Qual Saf 2019 Mar 20. Epub 2019 Mar 20.

QURE Healthcare, San Francisco, California, USA

Background: Hospitalist medicine was predicated on the belief that providers dedicated to inpatient care would deliver higher quality and more cost-effective care to acutely hospitalised patients. The literature shows mixed results and has identified care variation as a culprit for suboptimal quality and cost outcomes. Using a scientifically validated engagement and measurement approach such as Clinical Performance and Value (CPV), simulated patient vignettes may provide the impetus to change provider behaviour, improve system cohesion, and improve quality and cost efficiency for hospitalists.

Right Heart Catheterization During Exercise in Patients with COPD-An Overview of Clinical Results and Methodological Aspects.

COPD 2018 Dec;15(6):588-599

c DRK-Kliniken Berlin-Westend, Klinik für Kardiologie , Berlin , Germany.

While right heart catheterization (RHC) at rest is the gold standard to assess pulmonary hemodynamics in patients with chronic obstructive pulmonary disease (COPD) and pulmonary hypertension (PH), the invasive measurement of exercise hemodynamics is less well established in this group. Since exercise hemodynamics are increasingly recognized as important clinical information in patients with PH, our goal was to review the literature in this field to provide a basis for clinical use, further studies, and future recommendations. We identified 69 studies (published since 1968) reporting RHC data in 2819 patients with COPD, of whom 2561 underwent exercise testing. Read More

MLN4924 protects against interleukin-17A-induced pulmonary inflammation by disrupting ACT1-mediated signaling.

Am J Physiol Lung Cell Mol Physiol 2019 Mar 20. Epub 2019 Mar 20.

Engineering Research Center of Cell & Therapeutic Antibody, Ministry of Education, School of Pharmacy, Shanghai Jiao Tong University, China.

An excessive inflammatory response in terminal airways, alveoli, and the lung interstitium eventually leads to pulmonary hypertension and chronic obstructive pulmonary disease. Proinflammatory cytokine interleukin-17A (IL-17A) has been implicated in the pathogenesis of pulmonary inflammatory diseases. MLN4924, an inhibitor of NEDD8-activating enzyme (NAE), is associated with the treatment of various types of cancers, but its role in the IL-17A-mediated inflammatory response has not been identified.

Activation of mTORC1/PGC1 axis promotes mitochondrial biogenesis and induces cellular senescence in the lung epithelium.

Am J Physiol Lung Cell Mol Physiol 2019 Mar 20. Epub 2019 Mar 20.

Center of Translational Medicine, Thomas Jefferson University, United States.

Cellular senescence is a biological process by which cells lose their capacity to proliferate yet remain metabolically active. Although originally considered a protective mechanism to limit the formation of cancer, it is now appreciated that cellular senescence also contributes to the development of disease, including common respiratory ailments, such as chronic obstructive pulmonary disease and idiopathic pulmonary fibrosis. While many factors have been linked to the development of cellular senescence, mitochondrial dysfunction has emerged as an important causative factor. Read More

Maintaining the benefits following pulmonary rehabilitation: Achievable or not?

Respirology 2019 Mar 19. Epub 2019 Mar 19.

Faculty of Health Sciences, The University of Sydney, Sydney, NSW, Australia.

Pulmonary rehabilitation (PR) improves exercise capacity, health-related quality of life (HRQoL) and dyspnoea in patients with COPD and other lung conditions. Once PR is completed, the benefits gained begin to decline unless patients continue to exercise regularly. Due to limited evidence in other lung conditions, this review aims to examine the current evidence regarding maintenance exercise programmes for patients with COPD and to determine the types of programmes that are able to maintain the benefits gained from PR to 12 months and longer.

Pulmonary Diseases and Ageing.

Authors:
Peter J Barnes

Subcell Biochem 2019 ;91:45-74

Airway Disease Section, National Heart and Lung Institute, Imperial College, London, UK.

Chronic obstructive pulmonary disease (COPD) and idiopathic pulmonary fibrosis are regarded as a diseases of accelerated lung ageing and show all of the hallmarks of ageing, including telomere shortening, cellular senescence, activation of PI3 kinase-mTOR signaling, impaired autophagy, mitochondrial dysfunction, stem cell exhaustion, epigenetic changes, abnormal microRNA profiles, immunosenescence and a low grade chronic inflammation due to senescence-associated secretory phenotype (SASP). Many of these ageing mechanisms are driven by exogenous and endogenous oxidative stress. There is also a reduction in anti-ageing molecules, such as sirtuins and Klotho, which further accelerate the ageing process. Read More

The burden of pertussis in older adults: what is the role of vaccination? A systematic literature review.

Expert Rev Vaccines 2019 Mar 19. Epub 2019 Mar 19.

a GSK , Avenue Fleming 20, 1300 Wavre , Belgium.

Introduction: Pertussis (whooping cough) is a vaccine-preventable disease; however, neither natural- nor vaccine-induced protection is life-long. Although generally not severe in adults, pertussis can be associated with complications in patients with chronic conditions such as asthma or chronic obstructive pulmonary disease, and can be readily transmitted to more vulnerable populations, including neonates before they complete their primary vaccination. Furthermore, as the global population ages, the health and economic burden of the disease is expected to rise. Read More

Respirology 2019 Mar 18. Epub 2019 Mar 18.

Faculty of Science, School of Human Sciences and School of Agriculture and Environment, The University of Western Australia, Perth, WA, Australia.

Respiratory diseases, such as influenza infection, acute tracheal bronchitis, pneumonia, tuberculosis, chronic obstructive pulmonary disease, asthma, lung cancer and nasopharyngeal carcinoma, continue to significantly impact human health. Diseases of the lung and respiratory tract are influenced by environmental conditions and socio-economic factors; however, many of these serious respiratory disorders are also rooted in genetic or epigenetic causes. Clustered regularly interspaced palindromic repeats (CRISPR) and CRISPR-associated (Cas) proteins, isolated from the immune system of prokaryotes, provide a tool to manipulate gene sequences and gene expression with significant implications for respiratory research.

Office-Based Sedation/General Anesthesia for COPD Patients, Part II.

Anesth Prog 2019 ;66(1):44-51

Private Practice, CarePoint Anesthesia, Denver, Colorado.

The safe treatment of patients with chronic obstructive pulmonary disease (COPD) in dental office office-based settings can be quite complex without a current understanding of the etiology, course, severity, and current treatment modalities of the disease. The additional concerns of providing sedation and/or general anesthesia to patients with COPD in settings outside of a hospital demand thorough investigation of individual patient presentation and realistic development of planned treatment that patients suffering from this respiratory condition can tolerate. Along with other co-morbidities, such as advanced age and potential significant cardiovascular compromise, the dental practitioner providing sedation or general anesthesia must tailor any treatment plan to address multiple organ systems and mitigate risks of precipitating acute respiratory failure from inadequate pain and/or anxiety control.

What We Already Know About This Topic: Airway closure has been described in chronic obstructive pulmonary disease, acute respiratory distress syndrome, and cardiac arrest patientsThis phenomenon makes tidal inflation start only after a critical airway opening pressure is overcomeAlthough previously reported during general anesthesia, airway closure was partially misinterpreted WHAT THIS ARTICLE TELLS US THAT IS NEW: Airway closure affects a relevant proportion of obese patients undergoing general anesthesia in supine position, with a variable degree of airway opening pressureWith Trendelenburg pneumoperitoneum, airway opening pressure increases consistently with esophageal pressure and pneumoperitoneum insufflation pressure: consequently, transalveolar pressure, lung volumes, and alveolar recruitment do not varyAirway closure yields bedside misinterpretation of respiratory mechanics and underestimation of actual alveolar pressure in the intraoperative settingIt is an occult phenomenon that generates an airway pressure threshold, whereby inspiratory gas does not inflate the lung unless the airway opening pressure is exceeded BACKGROUND:: Airway closure causes lack of communication between proximal airways and alveoli, making tidal inflation start only after a critical airway opening pressure is overcome. The authors conducted a matched cohort study to report the existence of this phenomenon among obese patients undergoing general anesthesia.

Methods: Within the procedures of a clinical trial during gynecological surgery, obese patients underwent respiratory/lung mechanics and lung volume assessment both before and after pneumoperitoneum, in the supine and Trendelenburg positions, respectively. Read More

Modern Innovative Solutions to Improve Outcomes in Asthma, Breathlessness, and Chronic Obstructive Pulmonary Disease (MISSION ABC): Protocol for a Mixed-Methods Study.

JMIR Res Protoc 2019 Mar 18;8(3):e9228. Epub 2019 Mar 18.

Research and Innovation, Portsmouth Hospitals NHS Trust, Portsmouth, United Kingdom.

Background: A high proportion of the costs for respiratory diseases are generated by a relatively small group of patients with severe disease (recognized or unrecognized) or complex problems that include multimorbidity, at-risk behaviors, and socioeconomic disadvantage. These patients often struggle to engage with the structured, proactive, care approaches for chronic disease management advocated for asthma and chronic obstructive pulmonary disease (COPD), resulting in repeated emergency use of both primary and secondary health care. An integrated approach for the management of complex patients, incorporating both specialist and primary care teams' expertise, may be effective in improving outcomes for such high-risk patients.

Effect of Hypoxemia in the Determination of Short-Term Prognosis of Coronary Artery Bypass Graft Patients: A Prospective Study.

Anesth Pain Med 2019 Feb 16;9(1):e81785. Epub 2019 Feb 16.

Department of Anesthesiology, Pain and Critical Care, Tehran University of Medical Sciences, Tehran, Iran.

Background: Respiratory failure and hypoxemia are the known complications of anesthesia and surgery. As a major surgery mainly at advanced ages, the coronary artery bypass graft (CABG) surgery could lead to hypoxemia in the early post-operative phase. Currently, the fraction of partial pressure of arterial oxygen to the fraction of inspired oxygen (PiO/FiO) is used to determine the severity of the respiratory assault. Read More

Extrafine triple therapy delays COPD clinically important deterioration vs ICS/LABA, LAMA, or LABA/LAMA.

Int J Chron Obstruct Pulmon Dis 2019 28;14:531-546. Epub 2019 Feb 28.

Section of Cardiorespiratory and Internal Medicine, Department of Medical Sciences, University of Ferrara, Ferrara, Italy.

Background: Current pharmacological therapies for COPD improve quality of life and symptoms and reduce exacerbations. Given the progressive nature of COPD, it is arguably more important to understand whether the available therapies are able to delay clinical deterioration; the concept of "clinically important deterioration" (CID) has therefore been developed. We evaluated the efficacy of the single-inhaler triple combination beclometasone dipropionate, formoterol fumarate, and glycopyrronium (BDP/FF/G), using data from three large 1-year studies.
