Objectives and Class Participation
TiMM is structured to provide you with the experience of learning about an area of clinical medicine and reading state-of-the-art papers in a related discipline of basic science. Creating connections between scientific advances and clinical need is something that you, as physician-scientists, will do for the remainder of your career, and is one of the reasons this course has been popular with the students who take it as well as the faculty who participate as instructors. Each student will be part of two group presentations, but every student will actively participate in every session. The success of the class depends on you – in particular, on the quality of the discussion. Half of your grade will reflect your participation, and half will depend on the two presentations. To make the sessions interactive, we expect you to have read the papers and thought about the topic before each class. This class is different from other courses during your first year – it challenges you to read papers critically, design thought experiments, and generate hypotheses that (if you do your job well) no one in the class will have thought of before. We should also note that you should let us know in advance if you will need to miss a class.
Presenting in TiMM
Below is an outline of how to approach a TiMM presentation. You and the other member(s) of your group should plan to meet as a group with your preceptor twice, the first time at least two weeks before the presentation. Although each member of the group is responsible for covering a specific part of the topic, you should work as a team: the best sessions come from groups that coordinate their presentations. It is critical that the components be well integrated and teams should strive to avoid redundancy in the presentations. Since time is limited, each group should have a well-organized plan for presentation in order to maximize their ability to effectively convey the major discussion points. Once you have a presentation prepared, try to practice it a few times with your partners and (even better) in front of colleagues who are unfamiliar with the material. The goal of your presentation is to stimulate discussion on the part of your colleagues, who will all have read and thought about the assigned papers. You should pose questions directly to the class to stimulate discussion. In addition, most students in past years have found it helpful to include slides that highlight important questions and discussion points. Providing the information on this slide to your classmates by email before the class can be a great way to stimulate their thinking even before class meets.
Clinical review: Plan for 15 minutes
Outline for presentation: We strongly encourage you to include a case study as part of your clinical presentation. This can help the members of the class better “visualize” the disease. Your preceptor will be invaluable in helping you prepare a case and highlight the essential features of the disease. Keep in mind that it’s not necessary to be exhaustive – one of the most effective case presentations given in this class was a graph of Lou Gehrig’s batting average to illustrate the effects of ALS.
Definition: Define the disease in one or two sentences. For example: myocardial infarction results from the formation of thrombi in the coronary arteries at sites of atherosclerosis leading to secondary death of heart muscle.
Epidemiology: In two or three sentences, introduce the importance of this disease by discussing the Who, Where, and When of the disease. Some diseases will be rare, others will be common.
Clinical presentation and diagnosis: For TiMM purposes, keep this lean and mean. Briefly tell us how people with this disease present: what do they complain about (i.e. symptoms), what is found on physical examination, what are the clinical laboratory findings? For genetic diseases, is there a screen that can be performed in utero or on potential carriers? Be brief and don’t worry about mentioning everything.
Clinical treatment and prognosis: What is the current treatment and how effective is it? What is the long-term outlook for individuals with this disease? Again, don’t be exhaustive. The idea is to discuss how effective modern medicine is in treating and preventing the disease. Try to focus your clinical presentation anticipating the associated research papers.
Pathogenesis: This should segue into the research paper(s). Briefly summarize what is believed to underlie the disease process at the cellular and molecular level. Be very specific and limit your discussion to one slide related specifically to the disease. Summarize the outstanding questions that need to be answered to understand this disease at a basic level.
Science presentations: Plan for 15-20 minutes each
There will be two, or in some cases three, presentations following the clinical introduction. These short presentations will include either one paper with discussion or perhaps two papers. It will be up to each group to decide how to divide the time in these didactic presentations. However, keep in mind that 15-20 minutes is not enough time to fully digest a paper, or discuss all the points that these papers may bring up, and therefore it is crucial that you be strategic and selective in your presentations. (We should note that there are various ways of dividing these presentations up – in addition to discussing the major findings, one presenter may wish to go into details regarding technique – i.e. giving a particular functional “activity,” how could one clone “the gene?” Importantly, though, these should be points that would not be encountered in a standard medical school class.)
Some things to think about as you are organizing the presentations:
Overall: These papers have been chosen because they represent the state of the art, thus the goal of this part of the presentation is not to critique the papers as in a journal club but rather to focus on explaining the research from a broad perspective. Why were the authors interested in a particular question, how did they choose to answer it, what did they learn? The idea behind this part of the session (and indeed the whole course) is explore the link between a clinical question (which may be centuries old) and the scientific approach to an answer (which is often based on a method or data available for less than a few years). What is the question? What aspect of a disease that is not understood is being addressed? Be specific and state this in one or two sentences. The importance of this question should be clear after hearing the clinical overview. Of note, it is OK to call on your classmates; this can be an effective way of achieving active participation!
Background: Scientific questions are usually specific and build on previous experiments. Summarize using a diagram the specific state of the field prior to this paper. Don’t be exhaustive; use the details that pertain to this paper only. Try to make it simple, even if it isn’t! We can hammer out the important details together during discussion. Most selected papers will have enough background in the introduction or in accompanying editorials (e.g. news and views) to help you here but you may need a review paper. Ask your preceptor for guidance.
The approach: How was the experiment designed and why? Sometimes the findings are fortuitous, but most scientific discovery is planned. Briefly outline the approach to the question. Don’t talk about standard scientific techniques but do elaborate on the use of a new method if you feel it was crucial to the success of the investigators. Keep in mind that one of your colleagues may have already discussed a key method in detail. If a paper draws on methods that have been discussed in an earlier session of TiMM, you should feel comfortable building on that prior discussion and try to avoid redundancy in reviewing basic methods.
Methods: If there is a method utilized in the paper that requires special attention, one of the presenters should take the opportunity to discuss the method (see above). Ideally, a method discussion may be included for an approach that has fairly broad application but is not widely understood and would benefit from a detailed explanation. Questions to address during a method presentation: What is the method in practical terms: how is it performed, what does it measure? How is this method applied scientifically? Are there complementary methods that might be used to confirm or test results obtained using this approach?
Questions: Plan for 5-10 mintues
The formal presentations should be done at 4:30 pm. At this time, there will be room for any questions, provided they are not critical areas for discussion.
Overall topic discussion: Plan for 25-30 minutes
The major goal of TiMM is to move beyond the rote learning of a clinical presentation and journal club to stimulate students to think as physician scientists: What is the next important question? What technical hurdles need to be overcome, and how might I do that? What other techniques or fields of research could be brought to bear on the problem?
The presenters will have prepared a list of 3-4 “discussion points” (which will have been distributed to the class earlier by email) which will serve as a launchpad for discussing future directions, technical or conceptual hurdles, etc. It is expected that everyone will participate in the discussion. Broad class participation is essential to the educational mission of this class. Your preceptor will be present during your presentation and can be thought of as a resource to weigh in on the important discussion questions. Ben and Rahul may also help raise important discussion points. However, you should try to lead to discussion and extract as much as possible from your classmates. The best presentations naturally foster a high level of engagement from your fellow students by stimulating them to think and contribute. We will attempt to end class on time (class is 90 minutes long).
Feedback on your presentation will come in several forms. The course directors and session preceptors will provide you with verbal feedback at the end of your presentation. Additionally, you will each be asked to anonymously provide written feedback on one group's presentation. Both of these feedback forums will focus on the clarity and organization of the presentation, along with your group's ability to guide and direct the discussion.
