For the first hundreds of years of modern medicine, progress was a process of trial and error, and to be honest, it was often fatal error, such as bloodletting, which killed the first US president George Washington. Where diseases were clearly understood, and where treatments obviously worked on most patients, such as penicillin for pneumonia, there was no need to delve deeper into questions of effectiveness. But for most conditions, the treatment benefits were modest and there was a need for improved ways of telling whether a new intervention was better than the previous standard treatment. And so scientists introduced a testing procedure for new treatments - the randomized controlled trial.

As the cost of developing new treatments grew, it became very important to detect the slightest improvement that could be attributed to the new drug in order to get it licensed and marketed. So the usual randomized trial was answering the following question: does this treatment work (for otherwise well people with just this single disease, with perfect adherence, treated by the best doctors, under idealised conditions)? But most patients have multiple diseases, imperfect adherence, ordinary doctors and non-ideal circumstances. These patients want to know whether a new treatment is likely to reduce important harms for ordinary people like them, receiving usual care. This mismatch meant that most trials were overestimating the real world effectiveness of new interventions.

In this MOOC, we are going to study this mismatch, and see what its effect is on modern medical care. One example of the studies we will discuss is the VIGOR trial. This influential drug trial resulted in the widespread global overuse of this drug, at a cost of wasted billions of dollars. Ironically, this drug, intended to reduce a problem in individuals, ended up causing more of the same problem in the population!

After we understand the consequences of designing the wrong kinds of trials, we will also look at how best to design pragmatic randomized trials, which answer the important questions that ordinary patients and decision makers in the real world most often ask. We will also explore how these can be combined with economic evaluations and qualitative research – to answer important questions about how much these interventions cost, and how they are experienced by the recipients.

Chronic pain is at epidemic levels and has become the highest-cost condition in health care. This course uses evidence-based science with creative and experiential learning to better understand chronic pain conditions and how they can be prevented through self-management in our cognitive, behavioral, physical, emotional, spiritual, social, and environmental realms.

El curso desarrolla las competencias necesarias para aplicar los primeros auxilios psicológicos a personas afectadas por situaciones estresantes y/o traumáticas: accidentes de tráfico, agresiones, muertes repentinas, pero también por catástrofes naturales y cualquier otro tipo de emergencias comunitarias o masivas.

Principles of Biochemistry integrates an introduction to the structure of macromolecules and a biochemical approach to cellular function. Topics addressing protein function will include enzyme kinetics, the characterization of major metabolic pathways and their interconnection into tightly regulated networks, and the manipulation of enzymes and pathways with mutations or drugs. An exploration of simple cells (red blood cells) to more complex tissues (muscle and liver) will be used as a framework to discuss the progression in metabolic complexity. Learners will also develop problem solving and analytical skills that are more generally applicable to the life sciences.

New in version 2, learners will explore how alteration of these metabolic pathways relates to the development and progression of some human diseases.

Billions of cells in the body die every day. How and why do these cells die? If you want to know the answers to these questions and if you also would like to know how scientists figured them out, this course might interest you.

Developmental psychology concerns itself with the changes (psychological and otherwise) that occur as a result of our physical and mental maturation. Typically, “development” refers to the systematic changes that take place between our conception and death. While this definition may seem quite broad, it will serve as a good starting point in our quest to understand the field of developmental psychology. The first thing we must realize as developmental psychologists is that our change is systematic. This means that the process by which we grow and mature over time is not defined by random, isolated events but by orderly and relatively long-term patterns. This also means that while individuals themselves may differ quite a bit, the developmental patterns that they undergo are similar. These concepts are crucial in that they allow us, as psychologists, to study the way in which people develop and to make predictions about the future based on that development. Developmental psychologists study both continuiti…

The level of popularity you experienced in childhood and adolescence is still affecting you today in ways that you may not even realize. Learn about how psychologists study popularity and how these same concepts can be used in adulthood to be more successful at work, become better parents, and have a happier life.

How do health professionals predict global patterns of disease? In the case of an epidemic, disaster, or armed conflict, how do experts determine what health care interventions to use? Is it possible to eradicate diseases like guinea worm and polio? How can health systems address their challenges?

In this course, learners will hear from leading experts as they engage with current issues and challenges in global health. The course will examine the global response to diseases, such as the developing Zika outbreak. The backbone of this learning experience is a set of 18 reviews, co-edited by David Hunter and Harvey Fineberg, published in The New England Journal of Medicine (NEJM). The combined reviews constitute an up-to-date survey of global health topics from authoritative leaders in the field, covering disease patterns and predictions, infectious and non-communicable diseases, and health systems and institutional responses.

Participants will read the reviews, hear from the authors through a series of interviews, and engage with the content and one another through assessments and discussion questions.
