In the week just before Christmas, HtC approached me by asking whether or not I would like to join the editorial board of BMC Thrombosis Journal as an Associate Editor. the aims and scope of the journal, taken from their website:

“Thrombosis Journal  is an open-access journal that publishes original articles on aspects of clinical and basic research, new methodology, case reports and reviews in the areas of thrombosis.Topics of particular interest include the diagnosis of arterial and venous thrombosis, new antithrombotic treatments, new developments in the understanding, diagnosis and treatments of atherosclerotic vessel disease, relations between haemostasis and vascular disease, hypertension, diabetes, immunology and obesity.”

I talked to HtC, someone at BMC, as well as some of my friends and colleagues whether or not this would be a wise thing to do. Here is an overview of the points that came up:

Experience: Thrombosis is the field where I grew up in as a researcher. I know the basics, and have some extensive knowledge on specific parts of the field. But with my move to Germany, I started to focus on stroke, so one might wonder why not use your time to work with a stroke related journal. My answer is that the field of thrombosis is a stroke related field and that my position in both worlds is a good opportunity to learn from both fields. Sure, there will be topics that I have less knowledge off, but here is where an associate editor should rely on expert reviewers and fellow editors.

This new position will also provide me with a bunch of new experiences in itself: for example, sitting on the other side of the table in a peer review process might help me to better understand a rejection of one of my own papers. Bottom line is that I think that I both bring and gain relevant experiences in this new position.

Time: These things cost time. A lot. Especially when you need to learn the skills needed for the job, like me. But learning these skills as an associate editor is an integral part of the science apparatus, and I am sure that the time that I invest will help me develop as a scientist. Also, the time that I need to spend is not necessary the type of time that I currently lack, i.e. writing time. For writing and doing research myself I need decent blocks of time to dive in and focus  — 4+ hours if possible. The time I need to perform my associate editor tasks is more fragmented: find peer reviewers, read their comments and make a final judgement are relative fragmented activities and I am sure that as soon as I get the hang of it I can squeeze those activities within shorter slots of time. Perhaps a nice way to fill those otherwise lost 30 minutes between two meetings?

Open science: Thrombosis journal is part of the Biomed central family. As such, it is an 100% OA journal. It is not that I am an open science fanboy or sceptic, but I am very curious how OA is developing and working with an OA journal will help me to understand what OA can and cannot deliver.

Going over these points, I am convinced that I can contribute to the journal with my experience in the fields of coagulation, stroke and research methodology. Also, I think that the time that it will take to learn the skills needed are an investment that in the end will help me to grow as a researcher. So, I replied HtC with a positive answer. Expect email requesting for a peer review report soon!

New team member!

A couple of weeks ago I announced that my team was looking for a new post-doc. I received many applications, some even from as far as Italy and Spain. Out of this pile of candidates we were able to find an individual candidate who fulfilled all the requirements we had mind and than some. It is great that she will join the team in December. JH has worked in the field of epidemiology for quite some time and is not only experienced in setting up new projects and provide physicians with methodological input on their clinical research projects, but she also has a great interest in the more methodological side of epidemiology. For example, she is co-author/developer of the program DAGitty which can be used to draw causal diagrams. She is also speaker for the working group methodology of the German Society of Epidemiology (dgEpi). Her background in psychology also means that she brings a lot of knowledge on methods that we as a team do not have so far. In short, a great addition to the team. Welcome JH!

 

 

Berlin Epidemiological Methods Colloquium kicks of with SER event

A small group of epi-nerds (JLR, TK and myself) decided to start a colloquium on epidemiological methods. This colloquium series kicks off with a webcast of an event organised by the Society for Epidemiological Research (SER), but in general we will organize meetings focussed on advanced topics in epidemiological methods. Anyone interested is welcome. Regularly meetings will start in February 2017. All meetings will be held in English.
More information on the first event can be found below or via this link:

“Perspective of relative versus absolute effect measures” via SERdigital

Date: Wednesday, November 16th 2016 Time: 6:00pm – 9:00pm
Location: Seminar Room of the Neurology Clinic, first floor (Alte Nervenklinik)
Bonhoefferweg 3, Charite Universitätsmedizin Berlin- Campus Mitte, 10117 Berlin
(Map: https://www.charite.de/service/lageplan/plan/map/ccm_bonhoefferweg_3)

Description:
Join us for a live, interactive viewing party of a debate between two leading epidemiologists, Dr. Charlie Poole and Dr. Donna Spiegelman, about the merits of relative versus absolute effect measures. Which measure of effect should epidemiologists prioritize? This digital event organized by the Society for Epidemiologic Research will also include three live oral presentations selected from submitted abstracts. There will be open discussion with other viewers from across the globe and opportunities to submit questions to the speakers. And since no movie night is complete without popcorn, we will provide that, too! For more information, see: https://epiresearch.org/ser50/serdigital

The paradox of the BMI paradox

2016-10-19-17_52_02-physbe-talk-bs-pdf-adobe-reader

I had the honor to be invited to the PHYSBE research group in Gothenburg, Sweden. I got to talk about the paradox of the BMI paradox. In the announcement abstract I wrote:

“The paradox of the BMI paradox”
Many fields have their own so-called “paradox”, where a risk factor in certain
instances suddenly seems to be protective. A good example is the BMI paradox,
where high BMI in some studies seems to be protective of mortality. I will
argue that these paradoxes can be explained by a form of selection bias. But I
will also discuss that these paradoxes have provided researchers with much
more than just an erroneous conclusion on the causal link between BMI and
mortality.

I first address the problem of BMI as an exposure. Easy stuff. But then we come to index even bias, or collider stratification bias. and how selections do matter in a recurrence research paradox -like PFO & stroke- or a health status research like BMI- and can introduce confounding into the equation.

I see that the confounding might not be enough to explain all that is observed in observational research, so I continued looking for other reasons there are these strong feelings on these paradoxes. Do they exist, or don’t they?I found that the two sides tend to “talk in two worlds”. One side talks about causal research and asks what we can learn from the biological systems that might play a role, whereas others think with their clinical  POV and start to talk about RCTs and the need for weight control programs in patients. But there is huge difference in study design, RQ and interpretation of results between the studies that they cite and interpret. Perhaps part of the paradox can be explained by this misunderstanding.

But the cool thing about the paradox is that through complicated topics, new hypothesis , interesting findings and strong feelings about the existence of paradoxes, I think that the we can all agree: the field of obesity research has won in the end. and with winning i mean that the methods are now better described, better discussed and better applied. New hypothesis are being generated and confirmed or refuted. All in all, the field makes progress not despite, but because the paradox. A paradox that doesn’t even exist. How is that for a paradox?

All in all an interesting day, and i think i made some friends in Gothenburg. Perhaps we can do some cool science together!

predicting DVT with D-dimer in stroke patients: a rebuttal to our letter

2016-10-09-18_05_33-1-s2-0-s0049384816305102-main-pdf
Some weeks ago, I reported on a letter to the editor of Thrombosis Research on the question whether D-Dimer indeed does improve DVT risk prediction in stroke patients.

I was going to write a whole story on how one should not use a personal blog to continue the scientific debate. As you can guess, I ended up writing a full paragraph where I did this anyway. So I deleted that paragraph and I am going to do a thing that requires some action from you. I am just going to leave you with the links to the letters and let you decide whether the issues we bring up, but also the corresponding rebuttal of the authors, help to interpret the results from the the original publication.

ECTH 2016

Last week was the first edition of the European Congress on Thrombosis and Hemostasis in the Hague (NL). The idea of this conference is to provide a platform for european thrombosis researchers and doctors to meet in the dull years between ISTH meetings. There is a strong emphasis on enabling and training the young researchers, as can be from the different activities and organisational aspects. One os these things was the Junior advisory board, of which I was part. We had the task to give advice both solicited and unsolicited, and help organise and shape some of the innovative aspects. For example: we had the so-called fast and furious sessions, where authors of the best abstract were asked to let go of the standard presentation format and share their research TED talk style.

I learned a lot during these sessions, and even got in contact with some groups that have interesting methods and approaches that we might apply in our studies and patient populations. My thoughts: targeting FXII and FXI as well as DNAse treatment are the next big thing. We also had a great selection of speakers for meet-the-experts and how-to sessions. These sessions demanded active participation of all participants which is really a great way to build new collaborations and friendships.

The 5K fun run with 35+ participants was also a great succes.

The wednesday plenary sessions, including the talks on novel and innovative methods of scholarly communications as well as the very well received sessions from Malcolm Macloud on reducing research waste where inspiring to all. Missed it? do not worry, they have shared their slides online!

All in all, the conference was a great success in both numbers (750+ participants) as well as scientific quality. I am looking forward to the next edition, which will be held in Marseille in two years time. Hope to see you all there!
