Learn about your body's defenses against disease: how it can identify threats and coordinate counterattacks.
When you're sick, you may wonder, "Why me?" But the real question should be, "Why am I not sick all the time?" You might even ask, "Why does my body respond with a fever, and is it really a good idea to lower it?" This course explores immunology, how the body defends itself from constant assault by parasites and pathogens. This course will present the fundamentals of both innate and adaptive immunity, emphasizing functional interactions among cells and organs. We will cover signaling, pathogen recognition and the division of labor among myeloid, lymphoid and supporting cells. The subject matter will also supply health professionals and biomedical researchers with the basic vocabulary and concepts necessary to understand both clinical press releases and primary literature. The course materials also provide support to other immunology instructors by presenting difficult concepts in creative ways using analogies and models.
What you'll learn:
- The importance of disease defense
- The difference between innate and adaptive immunity
This course distills for you expert knowledge and skills mastered by professionals in Health Big Data Science and Bioinformatics. You will learn exciting facts about the human body biology and chemistry, genetics, and medicine that will be intertwined with the science of Big Data and skills to harness the avalanche of data openly available at your fingertips and which we are just starting to make sense of.
This course introduces how the human body works and how it is more than the sum of its parts. The human body is made up of many individual parts that work together in a highly interactive and coordinated way. This course introduces the building blocks that make up the body, and how these are structured and maintained at a cellular level. We highlight the cardiovascular, hormonal and nervous systems, as critical coordination and control parts of the body. We investigate the structure of the musculoskeletal system, and how it helps us move through, and manipulate, our environment. We conclude by reviewing how the body replaces itself to create a new human being.
In this course you will learn about the importance of quality in healthcare and how you can contribute by implementing a quality improvement (QI) project to improve processes of care and patient outcomes. You will learn about powerful tools to add to your QI ‘toolbox’ during short lectures and reflective exercises.
Learn the concepts, principles and practice of Emergency Management through real-world case studies. This course will take you on a journey through contemporary risk-based emergency management. From the origins of risk management in the ancient world, to new hazards and risk management approaches of the industrial era, command and control models introduced in the Cold War era, to more contemporary “all-hazards” to current “risk management” approaches. You will explore the rapidly growing and increasingly influential discipline through a study of real-world risk understanding, reduction, readiness, response and recovery examples. You will have opportunities to discuss what you learn with other students and build and test your growing knowledge through accessible tests.
This midwifery course covers the history of the profession and what it means to be a midwife today. This course will benefit those who are interested in doing midwifery as a career choice. This course will allow you to see the scope of practice of the midwife and understand that the focus of midwifery care is the woman. If you are considering a career in midwifery or a parent–to-be, this course will give you insight into the world of the midwife, pregnancy and childbirth. You will explore the role of the midwife in working with women and their families during pregnancy, labour and birth and the time following birth when the woman is supported in her new role as a mother.
Explore four common diseases and body systems: how they work, how they are treated and prevented. Understanding Common Diseases is designed for everyone who cares about their health or is interested in knowing more about how their body works. Over the course of the subject, you will hear from patients with four different diseases: high blood pressure, heartburn, diabetes and the common cold. We have chosen these diseases as they all affect different body systems and occur commonly in the general public. We will be describing how patients experience the disease, the normal way the body system works and looking at how the disease affects function and how you and your doctor can best manage your health.
Understanding the clinical terms and abbreviations commonly used in U.S. hospitals is challenging. Adaptation to clinical language can be difficult for U.S. students entering the clinical area and even more so for international students whose primary language is not English. This course is designed to help both groups of students understand the terms and abbreviations commonly encountered during the first three months of clinical work on a U.S. hospital unit.
Public Mental Health is the application of the principles of medicine and social science to prevent the occurrence of mental and behavioral disorders and to promote mental health of the population. This course illustrates the principles of public health applied to depressive disorder, including principles of epidemiology, transcultural psychiatry, health services research, and prevention.
Clinical trials are experiments designed to evaluate new interventions to prevent or treat disease in humans. The interventions evaluated can be drugs, devices (e.g., hearing aid), surgeries, behavioral interventions (e.g., smoking cessation program), community health programs (e.g. cancer screening programs) or health delivery systems (e.g., special care units for hospital admissions). We consider clinical trials experiments because the investigators rather the patients or their doctors select the treatment the patients receive.
Isn’t it time to end the loss of life from preventable medical errors? Each year 100,000 patients die from preventable errors in the U.S. How can you help to change this intractable problem? Knowledge is power, and this course will provide you with a deep understanding of the problems and the solutions. You can become part of the solution.
The vital signs – heart rate, blood pressure, body temperature, respiration rate, and pain – communicate important information about the physiological status of the human body. In this six-part course we explore the anatomy and physiology underlying the vital signs so that you will develop a systematic, integrated understanding of how the body functions. Relevant body systems are reviewed including cardiovascular and respiratory, followed by explanations of how the function of these systems affects vital signs. We discuss normal ranges, normal variants, and the mechanisms that underlie changes in the objective measurement of vital signs. The course also includes demonstrations of appropriate techniques for measuring vital signs in yourself and others.
Precision medicine has the potential to change fundamentally how health care is practiced, but requires a health care workforce that understands the complexities of this field. One important component of Precision Medicine is the use of an individual’s genomic information to offer targeted treatment, tailored to the individual. Our course aims to provide participants with some baseline knowledge of genomics, an overview of the clinical applications of genomic medicine, the skills to evaluate the clinical validity and utility of new tests, and an appreciation of the associated ethical and social issues inherent in this field.
MOOCs – Massive Open Online Courses – enable students around the world to take university courses online. This guide, by the instructors of edX’s most successful MOOC in 2013-2014, Principles of Written English (based on both enrollments and rate of completion), advises current and future students how to get the most out of their online study, covering areas such as what types of courses are offered and who offers them, what resources students need, how to register, how to work effectively with other students, how to interact with professors and staff, and how to handle assignments. This second edition offers a new chapter on how to stay motivated. This book is suitable for both native and non-native speakers of English, and is applicable to MOOC classes on any subject (and indeed, for just about any type of online study).
