The breadth of family medicine in one meeting (opens the original)
Read excerpt
My wife and I returned last night from the annual Family Medicine Education Consortium meeting, which was held in Atlantic City this year. Despite the rainy weather, it was an enjoyable conference. I presented the latest evidence on multicancer blood tests, which are limited and imperfect tools that family doctors should think twice about ordering for their patients even if Galleri is approved by the U.S. Food and Drug Administration. Plenary speakers included family physician and
When ideology dictates science policy: Trofim Lysenko and Robert F. Kennedy, Jr. (opens the original)
Read excerpt
30 years ago, I took a college class on the history of Russian and Soviet science. One of the more infamous figures in an otherwise accomplished pantheon of scientists was a man named Trofim Lysenko, who rejected Mendelian genetics and espoused a form of agricultural pseudoscience. In a naturally self-correcting scientific system, he should have been an historical footnote, but by cleverly aligning his theories with Marxist ideology and ingratiating himself with Joseph Stalin, he managed to hold
e-Cigarettes for tobacco smoking cessation (opens the original)
Read excerpt

Discontinuing statins for primary prevention in older adults (opens the original)
Read excerpt
The major randomized controlled trials (RCTs) that established the benefits of statins in preventing atherosclerotic cardiovascular disease (ASCVD) generally did not enroll persons older than 75 years. Once a patient who has been taking a statin for primary prevention reaches that age, are there additional benefits to continuing it, or conversely, are there harms associated with discontinuing? In 2020, a systematic review of international guidelines on cardiovascular disease prevention found “li
Making measles great again, part 2 (opens the original)
Read excerpt
Six months ago, I wrote about why measles outbreaks matter to everyone. At that time, Lancaster County had recently diagnosed 5 people with measles, the first cases in Pennsylvania this year. As of today, the state Department of Health has recorded 296 cases of measles in 2026. Of those, 61 cases were confirmed in the past 7 days, most of these in Lancaster County. 52 patients became sick enough to be hospitalized; fortunately, no one has died. I a
