Announcing July BEMC Talk

Dear Berlin-area Epidemiological Methods Enthusiasts,

You are invited to our next BEMC Talk on Wednesday, July 4th.

BEMC Talk: Wednesday, July 4th, 2018 @ 4pm

“Applications of computer adaptive testing and item response theory in health outcomes assessment” – Professor Matthias Rose (Berlin)

  • If you haven’t already done so, please register in advance: https://goo.gl/forms/uPEdQQlPePd9vffo2
  • Description: “With an increased life-expectancy, the challenges for modern medicine have changed significantly over the last decades. Acute diseases are declining in western societies whereas the number of patients with chronic diseases increases and more patients are suffering from multimorbid conditions. Thus, the need to reconsider the measurement of treatment success has emerged, and in particular how to include the patients’ perspective into routine health outcome assessments. The talk will present new psychometric methods for the measurement of Patient-Reported Outcomes (PRO) promising to provide more comparable, more precise and less burdensome assessment tools.”
  • Location: Seminar room of the Neurology Clinic; Bonhoefferweg 3 entrance, 3rd floor, Charité – Campus Mitte

Upcoming Berlin Epi Events:

  • August – no BEMC Talk or JClub – Enjoy your summer break!
  • August 20-24th – IPH Intensive Short Course – “Advanced Epidemiologic Methods – causal research and prediction modeling” (Instructors: Rolf Groenwold/Maarten van Smeden)
  • September 5th – BEMC Talk – Prof Dr. Sebastian Baumeister, Regensburg

Announcing June BEMC Talk

Dear Berlin-area Epidemiological Methods Enthusiasts,

We are happy to announce our next BEMC Talk. Hope you can join us!

BEMC Talk: Wednesday, June 6th, 2018 @ 4pm

“Post-marketing studies and drug safety” – Dr. Christof Prugger (Berlin)

  • If you haven’t already done so, please register in advance: https://goo.gl/forms/Np1Q3JDkiaN5thdZ2
  • Description: “Drugs should be effective and safe, also in the long-term widespread use. Therefore, it is important for the efficacy and safety of medications to be demonstrated also after approval in so-called post-marketing studies (PMS). PMS should add to pharmacovigilance by assessing the risks and benefits of authorized drugs under real life conditions. This BEMC talk will focus on the current practice of PMS in Germany and Europe. It will emphasize methodological aspects of drug safety evaluation.”
  • Location: Seminar room of the Neurology Clinic (follow our signs); Bonhoefferweg 3 entrance, 3rd floor, Charité – Campus Mitte, à See: Campus Map

Mid-March update: JClub & Modeling nutritional data

Dear Epidemiological Methods Enthusiasts,

We have many exciting events coming up in the next several weeks and a few general announcements to share:

1. BEMC JClub: Weds., March 21st @ 4pm
After the fruitful discussion at last month’s journal club and Prof. Rauch’s Talk on competing risks, we again invite you to join us for our next methods-focused JClub.

  • Paper: Nienke A. de Glas, et al. Performing Survival Analyses in the Presence of Competing Risks: A Clinical Example in Older Breast Cancer Patients, JNCI (2016). https://doi.org/10.1093/jnci/djv366
  • Location: Seminar room of the Neurology Clinic (follow our signs); Bonhoefferweg 3, Charité – Campus Mitte
  • No need to register! Please contribute questions/remarks about the paper for discussion here: BEMC JClub Contribution Form.

2. BEMC Talk: Weds., April 4th @ 4pm
“Modeling of nutritional data”, Speaker: Dr. Sven Knüppel (DIfE, Potsdam)

  • Be sure to register in advance: https://goo.gl/forms/F1j3sUtxStZgVz3v1
    • Location: Seminar room of the Neurology Clinic (follow our signs); Bonhoefferweg 3, Charité – Campus Mitte
  • Description: “There is increasing interests in using mixed modeling that can provide estimates when complex data structures had been generated. One area of applying mixed models is the assessment of dietary intake that had been requested by several dietary assessment instruments. However, such modeling entails a multitude of challenges. In this BEMC talk, some of these challenges will be discussed and solutions presented. Experiences with the application of current statistical algorithms for estimating usual dietary intake are reported and the dietary assessment strategy of the German National Cohort (http://nako.de) will be shared.”

3. Mark your calendars for these upcoming Berlin epi events!
• April 11th @ 4pm – BEMC JClub – Paper will be posted online early April (note: as an exception, this time on 2nd Weds. of the month!)
• April 12-14th –IPH Intensive Short Course – “Principles and Methods of Epidemiology: Critiquing the Medical Literature” (Instructors: Julie Buring/Pamela Rist, Harvard) – Register here
• April 17th – @ 4pm IPH Lecture, Hörsaalruine, Virchowweg 16 – “The Complexity of Clinical Trials in the Prevention of Cardiovascular Disease: An Investigator’s Perspective” – Prof. Julie Buring, Boston (Harvard) – Register here
• May 2nd @ 4pm – BEMC Talk – “SEM & latent class analysis in the context of chronic disease” -Prof. Michael Eid, Berlin

BEMC Talk: March 7th, Competing risks

Dear Epidemiological Methods Enthusiasts,

Please join us for our March BEMC Talk:

“Planning and evaluating studies with time-to-event endpoints in a competing risk framework”

Speaker: Prof. Geraldine Rauch (Institute of Biometry and Clinical Epidemiology, Charité Universitätsmedizin Berlin)

Date: Wednesday, March 7th, 2018 /   Time: 4:00pm

Be sure to register in advance. Space is limited! Registration form: https://goo.gl/forms/67pKW1nkR80rm3eb2

Location: Seminar room of the Neurology Clinic, first floor (Alte Nervenklinik) – follow our signs, Bonhoefferweg 3, Charité Campus Mitte, 10117 Berlin; Campus Map

Description:

Clinical trials and epidemiologic studies commonly consider time-to-event endpoints that are often influenced by competing risks. In the presence of competing risks, standard survival analysis techniques, such as the Kaplan-Meier estimator, can yield seriously biased results. Although methods to account for competing risks are well known in the statistical literature, they are rarely applied in real studies. In this talk, different statistical approaches to account for competing risks are systematically compared, based on a simulation study and using the original data from a cardiology trial.

Please feel free to forward this invitation to interested colleagues. Hope to see you there!

Mark your calendars for upcoming Epi events:

March 21st @ 4pm – BEMC JClub  – Paper will be posted early March

February BEMC Talk: Rasch Modeling, QA for categorical data

Dear BEMC Community,

We’ve got another great BEMC Talk coming up for you (including a bonus hands-on workshop!)

“How to calibrate a questionnaire: quality-assuring categorical data with psychometric measurement theory” – Prof. Leslie Pendrill (RI:SE Metrology, Gothenburg)

Date: Wednesday, February 7th, 2018 /   Time: 4:00pm

Optional hands-on workshop to follow at 5:15pm, important: bring your laptops with MINISTEPS installed (free!) http://www.winsteps.com/ministep.htm

Space for both events is limited, so please register here in advance: https://goo.gl/forms/ukf6IavdmH04deOs2

We need your help! Please complete these two very short (1 min/each) questionnaires ahead of time so we have some data! Go to www.menti.com

->survey 1 code: 383775 , survey 2 code: 277042

Location: Seminar room of the Neurology Clinic, first floor (Alte Nervenklinik) – follow our signs, Bonhoefferweg 3, Charité Universitätsmedizin Berlin- Campus Mitte, 10117 Berlin–> see Campus Map

Description:

Measurements in the social sciences – with ‘instruments’ such as questionnaires, ability tests, – in education, healthcare and so on, need metrological quality assurance. A patient, for instance, expects the same quality of care wherever and whenever provided. This is a challenge since the usual tools of statistics do not always work on the categorical scales typical of such measurements. Modelling a measurement system where the instrument is a human being, and where the output is a performance metric, i.e., how well the set-up performs an assessment, appears to be a way forward. This BEMC Colloquium will present the necessary tools, such as psychometric Rasch measurement theory, and will be followed by a hands-on workshop where you yourselves can analyse cases such as (i) the Quality of the BEMC Colloquium Series and (ii) a Healthy Lifestyle.

Please share this invite with colleagues. Hope to see you there!


Coming up: we are trying something new – a BEMC journal club. Every third Wednesday of the month, we’ll read a paper together. Want to know more? Check out our website for the full schedule of JClub and Talk events and more info.
