Announcing October BEMC Talk

Dear Berlin-area Epidemiological Methods Enthusiasts,

You are invited to our next BEMC Talk on Wednesday, October 10th.

BEMC Talk: Wednesday, October 10th, 2018 @ 4pm

“Interactive DAGs: Exploring causality theory with Dagitty” – Dr. Johannes Textor (Nijmegen)

  • If you haven’t already done so, please register in advance: https://goo.gl/forms/nEchjAyHekh41o2u1
  • Description: “DAGs can be useful to aid causal interpretation of observational data, but sensibly applying DAGs in practice can be very challenging. The talk will discuss (1) how we can test whether a DAG is mis-specified or inconsistent with a dataset; (2) how we can deal with the issue of statistical equivalence between DAGs; and (3) how we can conduct DAG-based analyses when the presence of latent confounders cannot be ruled out. Hands-on examples will be given that use the website ‘dagitty.net’ and the accompanying R package.”
  • Location: Seminar room of the Neurology Clinic; Bonhoefferweg 3 entrance, 3rd floor, Charité – Campus Mitte

Upcoming Berlin Epi Events:

  • Oct 17th @ 4pm – no JClub. Join us at the IPH Lecture with Maria Glymour, ScD, MS, Professor at UCSF School of Medicine, as she presents “Are we ready for a biomarker-only based diagnostic criterion for research in Alzheimer’s Disease?”.
  • November 7th – BEMC Talk – “Multi state modelling in chronic diseases”  – Dr. Ralph Brinks, Düsseldorf
  • December 5th – BEMC Talk – Professor James Robins, Boston

Announcing September BEMC Talk

Dear Berlin-area Epidemiological Methods Enthusiasts,

You are invited to our next BEMC Talk on Wednesday, September 5th.

BEMC Talk: Wednesday, September 5th, 2018 @ 4pm

“Covariate selection in observational studies with limited knowledge of the true causal structure” – Dr. Sebastian Baumeister (Augsburg)

  • If you haven’t already done so, please register in advance: https://goo.gl/forms/MPnYT5NQVoeSKt3F3
  • Description: “Unconfoundedness is assumed to generate an unbiased estimate of a causal effect on an outcome. If there is sufficient knowledge on the underlying causal structure, established covariate selection criteria based on a causal directed acyclic graph (DAG) can be used to select subsets of observed pretreatment covariates. However, although variable selection approaches should be based on an understanding of the causal structure representing the common cause pathways between treatment and outcome, the true causal structure is rarely known. When knowledge of the causal structure is not sufficient for use of a DAG, alternative covariate selection strategies are needed. Common suggestions when the causal structure is only partially known include “all observed pretreatment covariates” (Rubin) or the “disjunctive cause criterion” (VanderWeele & Shpister). Data-driven procedures for selection of covariates have also been proposed (e.g., change-in-MSE, focused selection, CovSel). Defining subsets of covariates that are sufficient to control for confounding empirically is difficult in the absence of background knowledge on the causal data-generating mechanism because adjustment for covariates that are affected by the exposure or the outcome and adjustment for instruments can increase bias.”

July 18th: Next BEMC JClub

Dear friends of the BEMC,

Please join us for one last journal club before the summer break.

We’ll be reading:

Hernán MA, Robins JM. Using Big Data to Emulate a Target Trial When a Randomized Trial Is Not Available. Am J Epidemiol. 2016 Apr 15;183(8):758–64.

We will meet next week Wednesday, July 18th at 4pm at our usual location (Click here for all details and to send in your questions/comments on the paper in advance).

See you there!

Here’s a picture from the July 4th BEMC Talk- thanks to all who joined us and to Prof. Rose for a great talk!

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.”
