The astorb database at Lowell Observatory

The astorb database at Lowell Observatory is an actively curated catalog of all known asteroids in the Solar System. astorb has heritage dating back to the 1970s and has been publicly accessible since the 1990s. Work began in 2015 to modernize the underlying database infrastructure, operational software, and associated web applications. That effort involved the expansion of astorb to incorporate new data such as physical properties (e.g. albedo, colors, spectral types) from a variety of sources. The data in astorb are used to support a number of research tools hosted at https://asteroid.lowell.edu. Here we present a full description of the software tools, computational foundation, and data products upon which the astorb ecosystem has been built. (c) 2022 The Author(s).

Improving bilingual higher education: Training university professors in content and language integrated learning

Few studies have been conducted at the tertiary level on Content and Language Integrated Learning (CLIL). The current study aims to gather and share preliminary data concerning CLIL in higher education at several universities in different countries. A questionnaire and brief description of the project and its objectives were emailed to all teachers at a Spanish university listed as having taught content courses in English in the last academic year, and to all the Language Center directors within the network with instructions to pass the questionnaire along to the CLIL teachers at their respective universities. The questionnaire was answered by 168 teachers, with 79% of responses (n=133) coming from four universities in Spain, Malaysia, P.R. China, and Turkey. The questionnaire results were exported to Excel and analyzed using statistical software. This preliminary phase of the research project, in which quantitative data has been analyzed, shows that CLIL teachers are intrinsically-motivated, language proficient, and aware of the need to adapt material to the bilingual classroom. In the next, qualitative phase of the project, issues regarding English language assessment, use of L1 in the classroom and scaffolding will need to be analyzed in depth in order to propose guidelines for future good practices and bilingual teacher training.DOI: 10.18870/hlrc.v4i1.19

The "smoker's paradox" in patients with acute coronary syndrome: a systematic review

<p>Abstract</p> <p>Background</p> <p>Smokers have been shown to have lower mortality after acute coronary syndrome than non-smokers. This has been attributed to the younger age, lower co-morbidity, more aggressive treatment and lower risk profile of the smoker. Some studies, however, have used multivariate analyses to show a residual survival benefit for smokers; that is, the "smoker's paradox". The aim of this study was, therefore, to perform a systematic review of the literature and evidence surrounding the existence of the "smoker's paradox".</p> <p>Methods</p> <p>Relevant studies published by September 2010 were identified through literature searches using EMBASE (from 1980), MEDLINE (from 1963) and the Cochrane Central Register of Controlled Trials, with a combination of text words and subject headings used. English-language original articles were included if they presented data on hospitalised patients with defined acute coronary syndrome, reported at least in-hospital mortality, had a clear definition of smoking status (including ex-smokers), presented crude and adjusted mortality data with effect estimates, and had a study sample of > 100 smokers and > 100 non-smokers. Two investigators independently reviewed all titles and abstracts in order to identify potentially relevant articles, with any discrepancies resolved by repeated review and discussion.</p> <p>Results</p> <p>A total of 978 citations were identified, with 18 citations from 17 studies included thereafter. Six studies (one observational study, three registries and two randomised controlled trials on thrombolytic treatment) observed a "smoker's paradox". Between the 1980s and 1990s these studies enrolled patients with acute myocardial infarction (AMI) according to criteria similar to the World Health Organisation criteria from 1979. Among the remaining 11 studies not supporting the existence of the paradox, five studies represented patients undergoing contemporary management.</p> <p>Conclusion</p> <p>The "smoker's paradox" was observed in some studies of AMI patients in the pre-thrombolytic and thrombolytic era, whereas no studies of a contemporary population with acute coronary syndrome have found evidence for such a paradox.</p

Neuroticism may not reflect emotional variability

Neuroticism is one of the major traits describing human personality, and a predictor of mental and physical disorders with profound public health significance. Individual differences in emotional variability are thought to reflect the core of neuroticism. However, the empirical relation between emotional variability and neuroticism may be partially the result of a measurement artifact reflecting neuroticism’s relation with higher mean levels—rather than greater variability—of negative emotion. When emotional intensity is measured using bounded scales, there is a dependency between variability and mean levels: at low (or high) intensity, it is impossible to demonstrate high variability. As neuroticism is positively associated with mean levels of negative emotion, this may account for the relation between neuroticism and emotional variability. In a metaanalysis of 11 studies (N = 1,205 participants; 83,411 observations), we tested whether the association between neuroticism and negative emotional variability was clouded by a dependency between variability and the mean. We found a medium-sized positive association between neuroticism and negative emotional variability, but, when using a relative variability index to correct for mean negative emotion, this association disappeared. This indicated that neuroticism was associated with experiencing more intense, but not more variable, negative emotions. Our findings call into question theory, measurement scales, and data suggesting that emotional variability is central to neuroticism. In doing so, they provide a revisionary perspective for understanding how this individual difference may predispose to mental and physical disorders

Prospective randomized trial of 5 days azacitidine versus supportive care in patients with lower-risk myelodysplastic syndromes without 5q deletion and transfusion-dependent anemia

Grupo Andaluz SMD.In this prospective trial, the efficacy of azacitidine in lower-risk myelodysplastic syndromes (LR-SMD) lacking del(5q) was compared to best supportive care (BSC) at 1:1. The primary endpoint was the achievement of erythroid hematologic improvement (HI-E) after nine cycles. Thirty-six patients received at least ≥1 cycle. HI-E was confirmed 44.4% randomized to Aza and in 5.5% of patients receiving BSC (p <.01). After entry in Aza extension period, transfusion independence was achieved in all Aza responders with a median duration of 50 weeks (range: 17–231). No significant differences were observed in secondary endpoints. Importantly, variant allele frequency (VAF) of some mutated genes (RET, SF3B1, ASXL1) decreased after 9 months of treatment in Aza-responder patients. In conclusion, LR-MDS patients lacking del5q and resistant to ESAs, who receive 5 days Aza, achieve TI in a substantial proportion of cases and results in modifications in mutational landscape.Peer Reviewe
