Debatable issues in automated ECG reporting
Although automated ECG analysis has been available for many years, there are some aspects which require to be re-assessed with respect to their value while newer techniques which are worthy of review are beginning to find their way into routine use. At the annual International Society of Computerized Electrocardiology conference held in April 2017, four areas in particular were debated. These were a) automated 12 lead resting ECG analysis; b) real time out of hospital ECG monitoring; c) ECG imaging; and d) single channel ECG rhythm interpretation. One speaker presented the positive aspects of each technique and another outlined the more negative aspects. Debate ensued. There were many positives set out for each technique but equally, more negative features were not in short supply, particularly for out of hospital ECG monitoring

Deep Learning in Cardiology
The medical field is creating large amount of data that physicians are unable
to decipher and use efficiently. Moreover, rule-based expert systems are
inefficient in solving complicated medical tasks or for creating insights using
big data. Deep learning has emerged as a more accurate and effective technology
in a wide range of medical problems such as diagnosis, prediction and
intervention. Deep learning is a representation learning method that consists
of layers that transform the data non-linearly, thus, revealing hierarchical
relationships and structures. In this review we survey deep learning
application papers that use structured data, signal and imaging modalities from
cardiology. We discuss the advantages and limitations of applying deep learning
in cardiology that also apply in medicine in general, while proposing certain
directions as the most viable for clinical use.Comment: 27 pages, 2 figures, 10 table
How long do top scientists maintain their stardom? An analysis by region, gender and discipline: evidence from Italy
We investigate the question of how long top scientists retain their stardom.
We observe the research performance of all Italian professors in the sciences
over three consecutive four-year periods, between 2001 and 2012. The top
scientists of the first period are identified on the basis of research
productivity, and their performance is then tracked through time. The analyses
demonstrate that more than a third of the nation's top scientists maintain this
status over the three consecutive periods, with higher shares occurring in the
life sciences and lower ones in engineering. Compared to males, females are
less likely to maintain top status. There are also regional differences, among
which top status is less likely to survive in southern Italy than in the north.
Finally we investigate the longevity of unproductive professors, and then check
whether the career progress of the top and unproductive scientists is aligned
with their respective performances. The results appear to have implications for
national policies on academic recruitment and advancement

Tweeting biomedicine: an analysis of tweets and citations in the biomedical literature
Data collected by social media platforms have recently been introduced as a
new source for indicators to help measure the impact of scholarly research in
ways that are complementary to traditional citation-based indicators. Data
generated from social media activities related to scholarly content can be used
to reflect broad types of impact. This paper aims to provide systematic
evidence regarding how often Twitter is used to diffuse journal articles in the
biomedical and life sciences. The analysis is based on a set of 1.4 million
documents covered by both PubMed and Web of Science (WoS) and published between
2010 and 2012. The number of tweets containing links to these documents was
analyzed to evaluate the degree to which certain journals, disciplines, and
specialties were represented on Twitter. It is shown that, with less than 10%
of PubMed articles mentioned on Twitter, its uptake is low in general. The
relationship between tweets and WoS citations was examined for each document at
the level of journals and specialties. The results show that tweeting behavior
varies between journals and specialties and correlations between tweets and
citations are low, implying that impact metrics based on tweets are different
from those based on citations. A framework utilizing the coverage of articles
and the correlation between Twitter mentions and citations is proposed to
facilitate the evaluation of novel social-media based metrics and to shed light
on the question in how far the number of tweets is a valid metric to measure
research impact.Comment: 22 pages, 4 figures, 5 table
