Stem Cells

Stem cells are cells with the potential to develop into many different types of cells in the body. They serve as a repair system for the body. There are two main types of stem cells: embryonic stem cells and adult stem cells.

Stem cells are different from other cells in the body in three ways:

• They can divide and renew themselves over a long time
• They are unspecialized, so they cannot do specific functions in the body
• They have the potential to become specialized cells, such as muscle cells, blood cells, and brain cells

Doctors and scientists are excited about stem cells because they could help in many different areas of health and medical research. Studying stem cells may help explain how serious conditions such as birth defects and cancer come about. Stem cells may one day be used to make cells and tissues for therapy of many diseases. Examples include Parkinson’s disease, Alzheimer’s disease, spinal cord injury, heart disease, diabetes, and arthritis.

Telehealth

What is telehealth?

Telehealth is the use of communications technologies to provide health care from a distance. These technologies may include computers, cameras, videoconferencing, the Internet, and satellite and wireless communications. Some examples of telehealth include:

• A “virtual visit” with a health care provider, through a phone call or video chat
• Remote patient monitoring, which lets your provider check on you while you are at home. For example, you might wear a device that measures your heart rate and sends that information to your provider.
• A surgeon using robotic technology to do surgery from a different location
• Sensors that can alert caregivers if a person with dementia leaves the house
• Sending your provider a message through your electronic health record (EHR)
• Watching an online video that your provider sent you about how to use an inhaler
• Getting an email, phone, or text reminder that it’s time for a cancer screening

What is the difference between telemedicine and telehealth?

Sometimes people use the term telemedicine to mean the same thing as telehealth. Telehealth is a broader term. It includes telemedicine. But it also includes things like training for health care providers, health care administrative meetings, and services provided by pharmacists and social workers.What are the benefits of telehealth?

Some of the benefits of telehealth include:

• Getting care at home, especially for people who can’t easily get to their providers’ offices
• Getting care from a specialist who is not close by
• Getting care after office hours
• More communication with your providers
• Better communication and coordination between health care providers
• More support for people who are managing their health conditions, especially chronic conditions such as diabetes
• Lower cost, since virtual visits may be cheaper than in-person visits

What are the problems with telehealth?

Some of the problems with telehealth include:

• If your virtual visit is with someone who is not your regular provider, he or she may not have all of your medical history
• After a virtual visit, it may be up to you to coordinate your care with your regular provider
• In some cases, the provider may not be able to make the right diagnosis without examining you in person. Or your provider may need you to come in for a lab test.
• There may be problems with the technology, for example, if you lose the connection, there is a problem with the software, etc.
• Some insurance companies may not cover telehealth visits

What types of care can I get using telehealth?

The types of care that you can get using telehealth may include:

• General health care, like wellness visits
• Prescriptions for medicine
• Dermatology (skin care)
• Eye exams
• Nutrition counseling
• Mental health counseling
• Urgent care conditions, such as sinusitis, urinary tract infections, common rashes, etc.

For telehealth visits, just like with an in-person visit, it is important to be prepared and have good communication with the provider.
