We recently published one of our projects embedded within the PROSCIS study. This follow-up study that includes 600+ men and women with acute stroke forms the basis of many active projects in the team (1 published, many coming up).
For this paper, PhD candidate PS measured auto-antibodies to the NMDAR receptor. Previous studies suggest that having these antibodies might be a marker, or even induce a kind of neuroprotective effect. That is not what we found: we showed that seropositive patients, especially those with the highest titers have a 3-3.5 fold increase in the risk of having a worse outcome, as well as almost 2-fold increased risk of CVD and death following the initial stroke.
Interesting findings, but some elements in our design do not allow us to draw very strong conclusions. One of them is the uncertainty of the seropositivity status of the patient over time. Are the antibodies actually induced over time? Are they transient? PS has come up with a solid plan to answer some of these questions, which includes measuring the antibodies at multiple time points just after stroke. Now, in PROSCIS we only have one blood sample, so we need to use biosamples from other studies that were designed with multiple blood draws. The team of AM was equally interested in the topic, so we teamed up. I am looking forward to follow-up on the questions that our own research brings up!
I am happy and honored that I can share that I am going to be part of the PLOS Biology editorial board. PLOS Biology has a special model for their editorial duties, with the core of the work being done by in-house staff editors – all scientist turned professional science communicators/publishers. They are supported by the academic editors – scientists who are active in their field and can help the in-house editors with insight/insider knowledge. I will join the team of academic editors.
Next to the meta-research manuscripts that need evaluation, I am also looking forward to just working with the professional and smart editorial office. The staff editors already teased a bit that a couple of new innovations are coming up. So, next to helping meta-research forward, I am looking forward to help shape and evaluate these experiments in scholarly publishing.
Every year there is a Neurology symposium organized in the quiet and beautiful town of Kuopio in Finland. Every three years, just like this year, the topic is stroke and for that reason, I was invited to be part of the faculty. A true honor, especially if you consider the other speakers on the program who all delivered excellent talks!
But these symposia are much more than just the hard cold science and prestige. It is also about making new friends and reconnecting with old ones. Leave that up to the Fins, whose decision to get us all on a boat and later in a sauna after a long day in the lecture hall proved to be a stroke of genius.
So, it was not for nothing that many of the talks boiled down to the idea that the best science is done with friends – in a team. This is true for when you are running a complex international stroke rehabilitation RCT, or you are investigating whether the lower risk in CVD morbidity and mortality amongst frequent sauna visitors. Or, in my case, about the role of hypercoagulability in young stroke – pdf of my slides can be found here –
Last week, I attended and spoke at the Maastricht Consensus Conference on Thrombosis (MCCT). This is not your standard, run-of-the-mill, conference where people share their most recent research. The MCCT is different, and focuses on the larger picture, by giving faculty the (plenary) stage to share their thoughts on opportunities and challenges in the field. Then, with the help of a team of PhD students, these thoughts are than further discussed in a break out session. All was wrapped up by a plenary discussion of what was discussed in the workshops. Interesting format, right?
It was my first MCCT, and I had difficulty envisioning how
exactly this format will work out beforehand. Now that I have experienced it
all, I can tell you that it really depends on the speaker and the people
attending the workshops. When it comes to the 20 minute introductions by the
faculty, I think that just an overview of the current state of the art is not
enough. The best presentations were all about the bigger picture, and had
either an open question, a controversial statement or some form of “crystal ball” vision of the future. It really is difficult to “find consensus” when there is no controversy as was the case in some
plenary talks. Given the break-out nature of the workshops, my observations are
limited in number. But from what I saw, some controversy (if need be only constructed
for the workshop) really did foster discussion amongst the workshop participants.
Two specific activities stand out for me. The first is the lecture and workshop on post PE syndrome and how we should able to monitor the functional outcome of PE. Given my recent plea in RPTH for more ordinal analyses in the field of thrombosis and hemostasis – learning from stroke research with its mRS- we not only had a great academic discussion, but made immediately plans for a couple of projects where we actually could implement this. The second activity I really enjoyed is my own workshop, where I not only gave a general introduction into stroke (prehospital treatment and triage, clinical and etiological heterogeneity etc) but also focused on the role of FXI and NETS. We discussed the role of DNase as a potential for co-treatment for tPA in the acute setting (talking about “crystal ball” type of discussions!). Slides from my lecture can be found here (PDF). An honorable mention has to go out to the PhD students P and V who did a great job in supporting me during the prep for the lecture and workshop. Their smart questions and shared insights really shaped my contribution.
Now, I said it was not always easy to find consensus, which
means that it isn’t impossible. In fact, I am
sure that themes that were discussed all boil down to a couple opportunities
and challenges. A first step was made by HtC and HS from the MCCT leadership
team in the closing session on Friday which will proof to be a great jumping
board for the consensus paper that will help set the stage for future research
in our field of arterial thrombosis.
I wrote about this in an earlier topic: JLR and I published a paper in which we explain that a single relative risk, irrespective of its form, is jus5t not enough. Some crucial elements go missing in this dimensionless ratio. The RR could allow us to forget about the size of the denominator, the clinical context, the crude binary nature of the outcome.
So we have provided some methods and ways of thinking to go beyond the RR in an tutorial published in RPTH (now in early view). The content and message are nothing new for those trained in clinical research (one would hope). Even for those without a formal training most concepts will have heard the concepts discussed in a talk or poster . But with all these concepts in one place, with an explanation why they provide a tad more insight than the RR alone, we hope that we will trigger young (and older) researchers to think whether one of these measures would be useful. Not for them, but for the readers of their papers.
