- Background: Early detection of coronary atherosclerosis using coronary computed tomography angiography (CCTA), in addition to coronary artery calcification (CAC) scoring, may help inform prevention strategies. We used CCTA to determine the prevalence, severity, and characteristics of coronary atherosclerosis and its association with CAC scores in a general population.Methods: We recruited 30 154 randomly invited individuals age 50 to 64 years to SCAPIS (the Swedish Cardiopulmonary Bioimage Study). The study includes individuals without known coronary heart disease (ie, no previous myocardial infarctions or cardiac procedures) and with high-quality results from CCTA and CAC imaging performed using dedicated dual-source CT scanners. Noncontrast images were scored for CAC. CCTA images were visually read and scored for coronary atherosclerosis per segment (defined as no atherosclerosis, 1% to 49% stenosis, or ≥50% stenosis). External validity of prevalence estimates was evaluated using inverse probability for participation weighting and Swedish register data.Results: In total, 25 182 individuals without known coronary heart disease were included (50.6% women). Any CCTA-detected atherosclerosis was found in 42.1%; any significant stenosis (≥50%) in 5.2%; left main, proximal left anterior descending artery, or 3-vessel disease in 1.9%; and any noncalcified plaques in 8.3% of this population. Onset of atherosclerosis was delayed on average by 10 years in women. Atherosclerosis was more prevalent in older individuals and predominantly found in the proximal left anterior descending artery. Prevalence of CCTA-detected atherosclerosis increased with increasing CAC scores. Among those with a CAC score >400, all had atherosclerosis and 45.7% had significant stenosis. In those with 0 CAC, 5.5% had atherosclerosis and 0.4% had significant stenosis. In participants with 0 CAC and intermediate 10-year risk of atherosclerotic cardiovascular disease according to the pooled cohort equation, 9.2% had CCTA-verified atherosclerosis. Prevalence estimates had excellent external validity and changed marginally when adjusted to the age-matched Swedish background population.Conclusions: Using CCTA in a large, random sample of the general population without established disease, we showed that silent coronary atherosclerosis is common in this population. High CAC scores convey a significant probability of substantial stenosis, and 0 CAC does not exclude atherosclerosis, particularly in those at higher baseline risk.

Tidskriftsartikel (refereegranskat)abstract
- Books containing both manuscript and print items were once common entities, just as it was customary to combine several printed texts into a collective binding, a Sammelband. This article discusses various ways that the two media, the handwritten and the printed, coincided and complemented each other in books from the hand-press era. That handwriting continued to be used for book production even after the introduction of printing is well documented, but the hybrid books with both media present still await their due attention from researchers, a need this article attempts to address. After a brief survey of how the media merged, two examples are described in more detail: they concern books which once belonged to the Jesuit College in Braniewo, Poland, but were taken as war booty and ended up in Uppsala University Library in the early seventeenth century.

Containing Multitudes : Codex Upsaliensis Graecus 8 in Perspective
- 2009
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This study employs as its primary source a codex from Uppsala University Library, Codex Upsaliensis Graecus 8. Its aim is to contribute to a better understanding of the Late Byzantine and post-Byzantine miscellaneous book. It is argued that multitext books reflect the time and society in which they were created. A thorough investigation of such books sheds light on the interests and concerns of the scribes, owners, and readers of the books. Containing some ninety texts of different character and from different genres, Codex Upsaliensis Graecus 8 is a complex creation, but still an example of a type of book that was common during the Middle Ages and the Renaissance. This study takes a comprehensive view of the book in its entirety, making sense of its different parts in relation to the whole with the help of codicology and textual analysis. With that approach the original idea of the book is brought to the fore, and the texts are studied in the same context that the main scribe Theodoros chose and the early owners and readers of the book encountered.Through a systematic codicological analysis, the overall structure of the codex is explored and suggestions are made concerning the provenance. The examination of the scribal work procedure becomes a means to profile this otherwise fairly unknown scribe. The texts are grouped and characterized typologically to illustrate connections throughout the whole book as well as in relation to the separate structural units. The role of micro-texts and secondary layers of inscription is also considered. From the perspective of usability the texts are divided into four categories: narrative texts, rhetorical texts, philosophical-theological texts, and practical texts. Three texts are studied in greater depth, as examples of the width of the scribe's interests and the variety of the book's contents.

Permeable Boundaries : Manuscript and Print in Concert in Early Modern Sweden
- 2011

Ingår i: LIR.journal. - 2001-2489. ; 1, s. 101-125
-
Tidskriftsartikel (refereegranskat)abstract
- This article intends to show how manuscript and printed texts continued to co-exist during the first centuries following the invention of the printing press. The two media depended on and nourished each other in various ways. The handwritten text usually precedes the print, but often the print also becomes a model for handwritten copies. Furthermore, there are texts – and books – which were never intended to be printed due to their personal character, or which could not be printed due to their particular or provocative contents. Variations within this concomitance of printed and handwritten material are discussed on the basis of a number of manuscript books from Skara Stifts- och Landsbibliotek. The examples include authors’ originals, miscellanies, study compendia, interfoliated and annotated prints, and books that display manuscript and printed text items bound together. The creation of apographs by Swedish war prisoners during their Siberian captivity is referred to as a case where sheer necessity brought about manuscript book production in the early eighteenth century.

Why ecosystem characteristics predicted from remotely sensed data are unbiased and biased at the same time – and how this affects applications
- 2024

Ingår i: Forest Ecosystems. - : Elsevier. - 2095-6355 .- 2197-5620. ; 11

Tidskriftsartikel (refereegranskat)abstract
- Remotely sensed data are frequently used for predicting and mapping ecosystem characteristics, and spatially explicit wall-to-wall information is sometimes proposed as the best possible source of information for decision-making. However, wall-to-wall information typically relies on model-based prediction, and several features of model-based prediction should be understood before extensively relying on this type of information. One such feature is that model-based predictors can be considered both unbiased and biased at the same time, which has important implications in several areas of application. In this discussion paper, we first describe the conventional model-unbiasedness paradigm that underpins most prediction techniques using remotely sensed (or other) auxiliary data. From this point of view, model-based predictors are typically unbiased. Secondly, we show that for specific domains, identified based on their true values, the same model-based predictors can be considered biased, and sometimes severely so.We suggest distinguishing between conventional model-bias, defined in the statistical literature as the difference between the expected value of a predictor and the expected value of the quantity being predicted, and design-bias of model-based estimators, defined as the difference between the expected value of a model-based estimator and the true value of the quantity being predicted. We show that model-based estimators (or predictors) are typically design-biased, and that there is a trend in the design-bias from overestimating small true values to underestimating large true values. Further, we give examples of applications where this is important to acknowledge and to potentially make adjustments to correct for the design-bias trend. We argue that relying entirely on conventional model-unbiasedness may lead to mistakes in several areas of application that use predictions from remotely sensed data.

Unraveling the logics of landscape
- 2014
-
Samlingsverk (redaktörskap) (övrigt vetenskapligt/konstnärligt)abstract
- Despite conceptual oscillations through times, the concept of landscape remains highly subjective, whereupon unraveling its 'logics' opens up to a plurality of interpretations. Accordingly, by focusing on the interconnections present in the non-haphazard production of landscape, this publication elaborates on how the rural landscape is valued, monitored, changed, harbored, used and misused, be it through actions, representations or metaphors. This book covers a broad range of topics, with contributions from scholars from more than 30 countries.
