Background: Hypothesizing that morphometric measurements are reliable markers of fitness in patients with lung cancer requiring aggressive surgical intervention, the purpose of this study was to assess their impact on postoperative outcome and long-term survival in patients with non-small cell lung cancer (NSCLC) requiring pneumonectomy.

Methods: Height, weight, and body mass index (BMI), as well as usual clinical, laboratory (including C-reactive protein [CRP] concentrations), and pathologic data were retrospectively retrieved from files of 161 consecutive patients treated by pneumonectomy for NSCLC, whose preoperative computed tomographic (CT) scans were available in the Picture Archive and Communication System (PACS) of the hospital. Cross-sectional areas of right and left psoas areas (measured by CT scan at the L3 level), perirenal fat thickness, and anterior subcutaneous tissue thickness at the left renal vein level were also assessed.

Clinical phenotyping is currently used to guide pharmacological treatment decisions in chronic obstructive pulmonary disease (COPD), a personalized approach to care. Precision medicine integrates biological (endotype) and clinical (phenotype) information for a more individualized approach to pharmacotherapy, to maximize the benefit versus risk ratio. Biomarkers can be used to identify endotypes.

Background: Long-term multicentre studies are subject to numerous factors that may affect the integrity of their conclusions. Quality control and standardization of data collection are crucial to minimise the biases induced by these factors. Nevertheless, tools implemented to manage biases are rarely described in publications about population-based cohorts.

This article reports on discussions at the 2015 workshop cosponsored by the International Pharmaceutical Aerosol Consortium on Regulation and Science (IPAC-RS) and the International Society for Aerosols in Medicine (ISAM), entitled "Regulatory and Patient Considerations for Inhalation Device Design, Development and Use." Key topics addressed at the workshop and presented here include patient-focused device design for orally inhaled products (OIPs), instructions for use (IFU), human factors, regulatory considerations in the United States and Europe, development of generic inhalers, quality-by-design, and change management of OIP devices. Workshop participants also identified several areas for further consideration and emphasized the need for increased focus on the patient to create therapeutic products (inclusive of device design, IFU, education, training) that support adherence with an individual patient's treatment regimen.

Background: Coactivation of agonist and antagonist lower limb muscles during gait stiffens joints and ensures stability. In patients with multiple sclerosis, coactivation of lower limb muscles might be a compensatory mechanism to cope with impairments of balance and gait.

Objective: The aim of this study was to assess coactivation of agonist and antagonist muscles at the knee and ankle joints during gait in patients with multiple sclerosis, and to evaluate the relationship between muscle coactivation and disability, gait performance, dynamic ankle strength measured during gait, and postural stability.

Background: The relevance of screening for airway obstruction in subjects not complaining of COPD symptoms may depend on the definition of airway obstruction. Response to exercise in asymptomatic subjects with persistent airway obstruction as defined by a postbronchodilator FEV1/FVC <5th centile lower limit of normal (LLN) remains unknown.

Methods: Dyspnoea (Borg scale), exercise tolerance and ventilatory constraints on tidal volume expansion were assessed in 20 consecutive asymptomatic subjects with persistent mild airway obstruction detected by screening (postbronchodilator FEV1/FVC z-score: -2.

Background: Most randomised clinical trials typically exclude a significant proportion of asthma patients, including those at higher risk of adverse events, with comorbidities, obesity, poor inhaler technique and adherence, or smokers. However, these patients might differentially benefit from extrafine-particle inhaled corticosteroids (ICS). This matched cohort, database study, compared the effectiveness of extrafine-particle with fine-particle ICS in a real-life population initiating ICS therapy in the Netherlands.

Background: Most guidelines recommend either a long-acting beta-agonist (LABA) plus an inhaled glucocorticoid or a long-acting muscarinic antagonist (LAMA) as the first-choice treatment for patients with chronic obstructive pulmonary disease (COPD) who have a high risk of exacerbations. The role of treatment with a LABA-LAMA regimen in these patients is unclear.

Methods: We conducted a 52-week, randomized, double-blind, double-dummy, noninferiority trial.

COPD is a heterogeneous disease responsible for a major burden on public and individual health. A wide variety of intrinsic and environmental risk factors are involved, and exert their influence at various time points during the life span of individuals. Knowledge of these factors is of utmost importance to develop appropriate screening and prevention programs, and may help improving the pathophysiological knowledge of the disease.

Background: The Timed Up and Go (TUG) test is widely used to assess locomotion in patients with stroke and is considered to predict the risk of falls. The analysis of locomotor trajectories during the TUG appears pertinent in stroke patients. The aims of this study were i) to analyze locomotor trajectories in patients with stroke during the walking and turning sub-tasks of the TUG, and to compare them with healthy subjects, ii) to determine whether trajectory parameters provide additional information to that provided by the conventional measure (performance time), iii) to compare the trajectory parameters of fallers and non-fallers with stroke and of patients with right and left hemisphere stroke, and iv) to evaluate correlations between trajectory parameters and Berg Balance Scale scores.

Pressurized metered-dose inhalers (pMDIs) are sometimes viewed as old-fashioned and as having been superseded by dry powder inhalers (DPIs). Here, we review the technological advances that characterize modern pMDIs, and consider how they can influence the effectiveness of drug delivery for patients with asthma and chronic obstructive pulmonary disease. Compared with old chlorofluorocarbon (CFC)-based inhalers, many hydrofluoroalkane (HFA)-driven pMDIs have more favorable plume characteristics such as a reduced velocity and a higher fine particle fraction; together, these advances have resulted in the development of pMDIs with reduced oropharyngeal deposition and increased lung deposition.
