INTRODUCTION Cardiovascular disease (CVD) is the leading cause of death worldwide, and genetic investigations into the human lipidome may provide insight into CVD risk. The aim of this study was to estimate the heritability of circulating lipid species and their genetic correlation with CVD traits. Methods Targeted lipidomic profiling was performed on 4492 participants from the Busselton Family Heart Study to quantify the major fatty acids of 596 lipid species from 33 classes. We estimated narrow-sense heritabilities of lipid species/classes, and their genetic correlations with eight CVD traits - body mass index, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol, triglycerides, total cholesterol, waist-hip-ratio, systolic blood pressure, and diastolic blood pressure. Results We report heritabilities and genetic correlations of new lipid species/sub-classes, including acylcarnitine, ubiquinone, sulfatide, and oxidized cholesteryl esters. Over 99% of lipid species were significology, Inc.There is growing interest in blood eosinophil counts in the management of chronic respiratory conditions such as asthma and chronic obstructive pulmonary disease [COPD]). Despite this, typical blood eosinophil levels in the general population, and the impact of potential confounders on these levels have not been clearly defined.We measured blood eosinophil counts in a random sample of 11 042 subjects recruited from the general population in Austria. We then (1) identified factors associated with high blood eosinophil counts (>75th percentile); and, (2) excluded subjects with these factors to estimate median blood eosinophil counts in a "healthy" sub-population (n=3641).We found that (1) in the entire cohort, age ≤18 years (odds ratio [OR] 2.41), asthma (OR 2.05), current smoking (OR 1.72), positive skin prick test (OR 1.64), COPD (OR 1.56), metabolic syndrome (OR 1.41), male sex (OR 1.36) and obesity (OR 1.16) were significantly (p less then 0.05) associated with high blood eosinophil counts (binary multivariable logistic regression analysis); and had an additive effect; (2) after excluding these factors, in those older than 18 years, blood eosinophil counts were higher in males than in females (median 120 [5%-95% CI 30-330] versus 100 [30-310] cells·µL-1, respectively) and did not change with age.Median blood eosinophil counts in adults are considerably lower than those currently regarded as normal, do not change with age beyond puberty, but are significantly influenced by a variety of factors which have an additive effect. These observations will contribute to the interpretation of blood eosinophil levels in clinical practice.

The aim of this international survey was to assess the global variability in prevention, diagnostic and treatment strategies for AE-IPF. MATERIAL AND METHODS Pulmonologists with ILD expertise were invited to participate in a survey designed by an international expert panel. RESULTS 509 pulmonologists from 66 countries responded. Significant geographical variability in approaches to manage AE-IPF was found. Common preventive measures included antifibrotic drugs and vaccination. Diagnostic differences were most pronounced regarding use of KL-6 and viral testing, while HRCT, BNP and D-Dimer are generally applied. High dose steroids are widely administered (94%); the use of other immunosuppressant and treatment strategies is highly variable. Very few (4%) responders never use immunosuppression. Antifibrotic treatments are initiated during AE-IPF by 67%. Invasive ventilation or extracorporeal membrane oxygenation are mainly used as a bridge to transplantation. Most physicians educate patients comprehensively on the severity of AE-IPF (82%) and consider palliative care (64%). CONCLUSION Approaches to the prevention, diagnosis and treatment of AE-IPF vary worldwide. Global trials and guidelines to improve the prognosis of AE-IPF are needed.

European and North American diagnostic guidelines recommend transmission electron microscopy (TEM) as one of a combination of tests to confirm a diagnosis. However, there is no definition of what constitutes a defect or consensus on reporting terminology. The aim of this project was to provide an internationally agreed ultrastructural classification for PCD diagnosis by TEM.A consensus guideline was developed by PCD electron microscopy experts representing 18 centres in 14 countries. An initial meeting and discussion were followed by a Delphi consensus process. The agreed guideline was then tested, modified and retested through exchange of samples and electron micrographs between the 18 diagnostic centres.The final guideline a) Provides agreed terminology and a definition of class 1 defects which are diagnostic for PCD; b) Identifies class 2 defects which can indicate a diagnosis of PCD in combination with other supporting evidence; c) Describes features which should be included in a ciliary ultrastructure report to assist multidisciplinary diagnosis of PCD d) Defines adequacy of a diagnostic sample.This tested and externally validated statement provides a clear guideline for the diagnosis of PCD by TEM which can be used to standardise diagnosis internationally.

EVLP has also been explored as a platform for donor lung repair through injury specific treatments such as antibiotics or fibrinolytics. We hypothesised that actively expressed pathways shared between transplantation and EVLP may reveal common mechanisms of injury and potential therapeutic targets for lung repair prior to transplantation. MATERIALS AND METHODS A retrospective transcriptomics analyses were performed with peripheral tissue biopsies from "donation after brain death" lungs, with 46 pre/post-transplant pairs and 49 pre/post-EVLP pairs. Pathway analysis was used to identify and compare the responses of donor lungs to transplantation and to EVLP. RESULTS Twenty-one pathways were enriched predominantly in transplantation, including upregulation of lymphocyte activation and cell death, and downregulation of metabolism and protein synthesis.
