Podcast 222: Growing prominence of NPs in primary care

(1 votes, average: 5.00 out of 5)

This time we talk with Dr. Hilary Barnes, first author of a Health Affairs paper: “Rural and Nonrural Primary Care Physician Practices Increasingly Rely on Nurse Practitioners.”

I thought listeners might want to know more about the dramatic change in the way primary care is acquiring, in Barnes’s words, an “increasing interdisciplinary character.”

Podcast 221: Pertussis makes a comeback — kids have an outsize role

(2 votes, average: 4.00 out of 5)

What’s causing this resurgence, and what’s to be done? Pejman Rohani talks about his Science Translational Medicine study that used “gold standard” historical data to examine possible causes.

He and his colleagues conclude that, as with mumps, slowly waning vaccine protection is at play. However, they identify the “core transmission group” as schoolchildren, who have a greater frequency of contacts. Adults, they find, have “at most a minor role.”

Podcast 220: Mumps outbreaks — blame waning protection, not new viruses or bad vaccines

(2 votes, average: 5.00 out of 5)

Mumps outbreaks keep happening, even among vaccinated groups. Why?

Our guest, Joseph Lewnard, and his coauthor, Yonstan Grad, probed studies of mumps vaccine efficacy carried out over five decades. They show that the fault, dear clinician, is not in our vaccines or new viral strains, but in ourselves. Our bodies slowly lose their immune response after vaccination, and about 25 years after the last vaccine dose, it’s gone.

Listen in.

Podcast 218: Better integration of midwifery associated with better birth outcomes

(2 votes, average: 4.50 out of 5)

An analysis of the states’ integration of midwifery into their healthcare systems concludes that better integration led to better outcomes for mothers and babies.

We discuss this with Dr. Saraswathi Vedam, the study’s first author.

Podcast 217: Aspirin and rivaroxaban “comparably effective and safe” for prophylaxis after arthroplasty

(1 votes, average: 4.00 out of 5)

The EPCAT II trial examined whether aspirin and rivaroxaban were clinically equivalent in the extended prophylaxis of venous thromboembolism after hip or knee replacement. They proved “comparably effective and safe,” according to our guest, Dr. David Anderson, the study’s first author. An editorial in the New England Journal of Medicine, where the study appeared in February, calls the results practice-changing. One thing was sure from the outset — aspirin is cheaper than rivaroxaban by orders of magnitude.

A note to listeners: Dr. Anderson and I conducted the interview over several sessions, so the first-half audio sounds a bit rougher than the second. Your speakers don’t suddenly get better — my equipment does!
