148 – Transcranial Magnetic Stimulation

The opening of a new private clinic spurs Chris and Sophie to ask whether Transcranial Magnetic Stimulation (TMS) is real medicine or pseudoscience. How does a magnetic field stimulate the brain and how is this different from electric convulsive therapy (ECT)? Also, a brief digression on One Flew Over the Cuckoo’s Nest and other classic movies Sophie has never seen.   Become a supporter of our show today either on Patreon or through PayPal!

147 – Genetic Testing

How does genetic testing help doctors treat patients? How accurate are private companies like 23andMe? Does knowing your genetic risk help people lead healthier lives or is it just a waste of time and money? Sophie had a bunch of questions about how genetic testing is used in everyday medical practice and Chris was here to answer!   Become a supporter of our show today either on Patreon or through PayPal!

146 – Radon – the invisible houseguest

Chris and Sophie tackle Radon, the odorless, colorless, tasteless and very toxic gas that is present in about 1 in 5 homes. Why do we care? How do you test for it? What should do about it?

145 – Case Challenge: rare and common cardiac conditions

EPISODE 145 – Case Challenge: rare and common cardiac conditions Aigul returns with two new case challenges. The first is a very rare cardiac condition that Chris actually picked up on his first day of work (and made him a superstar for about a week). The other is a very common problem that highlights how difficult medical diagnosis can be in real life.  Become a supporter of our show today either on Patreon or through PayPal!

144 – Mommy Myths

143 – A possible diabetes cure using stem cells

Sophie joins Chris to unpack a new study about using stem cell derived cells transplanted into the pancreas of people with Type 1 diabetes. The early results showed 10 of the 12 patients who got the transplant no longer needed insulin. But the therapy comes with some risks because nothing in medicine is risk free. Is there a cure for a diabetes? Is it possible to treat diabetes without changing your diet? Listen to the episode to find out!
