- Objectives: To investigate if air pollution and greenness exposure from birth till adulthood affects adult asthma, rhinitis and lung function. Methods: We analysed data from 3428 participants (mean age 28) in the RHINESSA study in Norway and Sweden. Individual mean annual residential exposures to nitrogen dioxide (NO2), particulate matter (PM10 and PM2.5), black carbon (BC), ozone (O3) and greenness (normalized difference vegetation index (NDVI)) were averaged across susceptibility windows (0–10 years, 10–18 years, lifetime, adulthood (year before study participation)) and analysed in relation to physician diagnosed asthma (ever/allergic/non-allergic), asthma attack last 12 months, current rhinitis and low lung function (lower limit of normal (LLN), z-scores of forced expiratory volume in one second (FEV1), forced vital capacity (FVC) and FEV1/FVC below 1.64). We performed logistic regression for asthma attack, rhinitis and LLN lung function (clustered with family and study centre), and conditional logistic regression with a matched case-control design for ever/allergic/non-allergic asthma. Multivariable models were adjusted for parental asthma and education. Results: Childhood, adolescence and adult exposure to NO2, PM10 and O3 were associated with an increased risk of asthma attacks (ORs between 1.29 and 2.25), but not with physician diagnosed asthma. For rhinitis, adulthood exposures seemed to be most important. Childhood and adolescence exposures to PM2.5 and O3 were associated with lower lung function, in particular FEV1 (range ORs 2.65 to 4.21). No associations between NDVI and asthma or rhinitis were revealed, but increased NDVI was associated with lower FEV1 and FVC in all susceptibility windows (range ORs 1.39 to 1.74). Conclusions: Air pollution exposures in childhood, adolescence and adulthood were associated with increased risk of asthma attacks, rhinitis and low lung function in adulthood. Greenness was not associated with asthma or rhinitis, but was a risk factor for low lung function. © 2020 The Authors

- We present a new publicly available tool (DustPol) aimed to model the polarised thermal dust emission. The module DustPol, which is publicly available, is part of the ARTIST (Adaptable Radiative Transfer Innovations for Submillimetre Telescopes) package, which also offers tools for modelling the polarisation of line emission together with a model library and a Python-based user interface. DustPol can easily manage analytical as well as pre-gridded models to generate synthetic maps of the Stokes I, Q, and U parameters. These maps are stored in FITS format which is straightforwardly read by the data reduction software used, e. g., by the Atacama Large Millimeter Array (ALMA). This turns DustPol into a powerful engine for the prediction of the expected polarisation features of a source observed with ALMA or the Planck satellite as well as for the interpretation of existing submillimetre observations obtained with other telescopes. DustPol allows the parameterisation of the maximum degree of polarisation and we find that, in a prestellar core, if there is depolarisation, this effect should happen at densities of 10(6) cm(-3) or larger. We compare a model generated by DustPol with the observational polarisation data of the low-mass Class 0 object NGC 1333 IRAS 4A, finding that the total and the polarised emission are consistent.

- MOTIVATION: Genome-scale 'omics' data constitute a potentially rich source of information about biological systems and their function. There is a plethora of tools and methods available to mine omics data. However, the diversity and complexity of different omics data types is a stumbling block for multi-data integration, hence there is a dire need for additional methods to exploit potential synergy from integrated orthogonal data. Rough Sets provide an efficient means to use complex information in classification approaches. Here, we set out to explore the possibilities of Rough Sets to incorporate diverse information sources in a functional classification of unknown genes. RESULTS: We explored the use of Rough Sets for a novel data integration strategy where gene expression data, protein features and Gene Ontology (GO) annotations were combined to describe general and biologically relevant patterns represented by If-Then rules. The descriptive rules were used to predict the function of unknown genes in Arabidopsis thaliana and Schizosaccharomyces pombe. The If-Then rule models showed success rates of up to 0.89 (discriminative and predictive power for both modeled organisms); whereas, models built solely of one data type (protein features or gene expression data) yielded success rates varying from 0.68 to 0.78. Our models were applied to generate classifications for many unknown genes, of which a sizeable number were confirmed either by PubMed literature reports or electronically interfered annotations. Finally, we studied cell cycle protein-protein interactions derived from both tandem affinity purification experiments and in silico experiments in the BioGRID interactome database and found strong experimental evidence for the predictions generated by our models. The results show that our approach can be used to build very robust models that create synergy from integrating gene expression data and protein features. AVAILABILITY: The Rough Set-based method is implemented in the Rosetta toolkit kernel version 1.0.1 available at: http://rosetta.lcb.uu.se/

- Background: Sleep disturbance and delirium are complications after surgical aortic valve replacement (SAVR) and transcutaneous aortic valve replacement (TAVI), especially in octogenarian patients. Sedatives and z-hypnotics are medications distributed to promote sleep. However, a knowledge-gap exists on patient experiences with these medications, and sleep and delirium after the cardiac treatment.Aim: To explore and describe how octogenarians suffering from delirium after SAVR/TAVI experience their sleep situation related to sedatives and z-hypnotics, in a long-term perspective.Methods An explorative and descriptive design with a longitudinal qualitative approach was applied. Inclusion criteria; age 80+, treated with SAVR or TAVI and had experienced delirium. Information about administration of sedatives and z-hypnotics was collected from the patients journals. The Confusion Assessment Method (CAM) was used to assess delirium, the Sleep Sufficient Index (SSI) and Minimal Insomnia Symptom Scale (MISS) were used to document self-reported sleep and insomnia. All measures were performed at baseline and daily the five first postoperative days. Ten patients were interviewed 6-12 months after treatment with focus on delirium. Five of these patients were re-interviewed four years later, focusing on their sleep situation.Findings: For the initial interview, five men and five woman, four after TAVI and six after SAVR, mean age 83 were included. One overarching theme revealed; hours in bed represented an emotional chaos. Three sub-themes described the patients experiences with sleep and delirium, a cascade of distressful experiences, the struggle between sleep and activity and elements influencing sleep. In the category physical sleep distractions, sleep medications emerged as a sleep disturbing element but also to evoke delirium. Patients described to be offered sedatives and z-hypnotics in hospital. However, they did not have a positive experience with this as the medication did not make them sleep better. Moreover, they associated the nightmares by the sedatives Four years after the cardiac treatment, the octogenarian patients described that medication did not have a sleep promoting effect, and they did not want it.Conclusion: Octogenarian patients are vulnerable to complications like sleep disturbances and delirium. In preventing and treating these conditions, health-care professionals should be aware of the effect and side-effect of sedatives and z-hypnotics in the octogenarian patients. Our findings show that medications should be cautiously used within this group of patients.
