Holism, Holes and Poles

(0) Comments | Posted January 28, 2015 | 2:40 PM

Integrative Medicine, now itself officially integrated into the name of its home at the NIH, the newly dubbed National Center for Complementary and Integrative Health, is a rhetorical lightning rod under any of its potential aliases. All related terms- alternative medicine, holistic medicine, complementary medicine, and so on...

Michael Davidson, the cardiothoracic surgeon shot and killed in Brigham and Women's Hospital last week by the distraught son of a woman on whom he had operated some time ago and who died in November, was a medical student of mine at Yale back in the early 1990s.

Measles in the Magic Kingdom? It's a Small World, After All

(34) Comments | Posted January 23, 2015 | 2:21 PM

One would think our recent experience with Ebola -- the rapid and predictable, albeit, rare transmission of the disease out from its site of origin to far-flung places around the globe, including here, and the attendant hysteria -- would have taught us already that when it comes to...

Are We Sitting on a Major Health Risk?

(0) Comments | Posted January 21, 2015 | 6:26 PM

The big medical news this week was that sitting hours a day is taking years from our lives, whether we exercise or not. We have heard similar things before, so the now reiterated message is: Yes, we are sitting on a major health risk. Sitting IS...

What's What in Nutrition? What's on First

(0) Comments | Posted January 20, 2015 | 3:08 PM

In that rightfully famous routine by Abbott and Costello, What, if you recall, was on second (base). Who was on first. I Don't Know was on third. And so on, into the mayhem of historically comedic genius.

Of course, comedy was the only real point of the routine....

Fatness, Fitness and Fiddling Around

(0) Comments | Posted January 16, 2015 | 2:55 PM

A new study about physical activity, obesity, and mortality has been propagating so many headlines and so much commentary, it's pretty much a given that if you are seeing this, you have seen something like: "inactivity kills more than obesity."

As is generally true in such...

Examining the Annual Exam

(19) Comments | Posted January 15, 2015 | 4:30 PM

In last week's New York Times, Dr. Ezekiel Emanuel suggested that this year's resolution might be to abandon the ritual of your annual physical. The title of his column, perhaps chosen by an editor to maximize glibness and thus provocation was: "Skip Your Annual Physical."

But permit me...

To Diet Or Not to Diet? Of Tests, Trees, and Forest

The Lumberjack World Championships, coming up for those interested in Hayward, Wisconsin in late July, 2015, appear to be very impressive. Contestants are judged on a diverse array of aptitudes, from chopping and sawing, to pole climbing and log rolling. One presumes the criteria for winning each of...

Bone Broth and Magic Beans

We are, it seems, unendingly as enthusiastic about dietary magic du jour as ever Jack was about his beans. And now it turns out that we have something else in common. Jack's giants were apparently inclined to grind bones to make bread. We are using them to make...

Cancer and Random Genes: Fortune Favors the Prepared

(10) Comments | Posted January 6, 2015 | 4:58 PM

A recent study in Science purportedly demonstrated that cancer is more random than previously thought. This, predictably, has led to high-profile publications in mainstream media suggesting that cancer results more from "bad luck" than factors over which we exercise some control.

If that epiphany bothered you,...

Who Are We? Of DNA, Drugs and Dinner

(1) Comments | Posted December 30, 2014 | 9:59 AM

There are many rousing lyrics in Les Misérables, probably my favorite of all musicals -- with some competition from Wicked, and Man of La Mancha. Among them is this: it is time for us all to decide who we are.

In Les Mis, this is a question pertaining to rather...

A Year Nearly Donne: Reflections on the Family of Man

No man is an island,
Entire of itself,
Every man is a piece of the continent,
A part of the main.
If a clod be washed away by the sea,
Europe is the less.
As well as if a promontory were.
As well...

What Really Matters Today (And Every Day)

As I write this, one of my daughters is in the hospital recovering from elective, but nonetheless somewhat urgent surgery. She will be fine, and likely come home later today. Still, the native rhythms of Katz family holiday preparation are much disturbed by worry, and the logistics of a family...

DNA, Dunkin' and Dingbats

(0) Comments | Posted December 16, 2014 | 11:22 AM

In the heady days of the genomic dawn -- not all that long ago, really -- we dreamed of dominating our DNA. Our hopes -- born in retrospect of characteristic Homo sapien hubris -- ran to wrestling with wayward ribonucleic acids; tinkering with our telomeres; and in all...

The Flu Vaccine: of Flubbing and Drubbing

(76) Comments | Posted December 5, 2014 | 11:26 AM

This year's flu vaccine, as you likely know, is taking a drubbing. The contention is that CDC flubbed, and didn't get quite the right flu strains in the mix. That is apparently true, although more the "fault" of the influenza virus and its natively wily ways,...

The Obesity Fix

(0) Comments | Posted December 3, 2014 | 2:57 PM

McKinsey & Company recently issued a report on effective means of fighting hyper-endemic obesity in the modern world. Among other things, they concluded that "implementing an obesity-abatement program on the required scale will not be easy." I presume that is intended to be somber, but the magnitude of...

Demystifying Calories: Already There and Miles to Go

(1) Comments | Posted December 2, 2014 | 1:32 PM

There are three good reasons to write about calories right now. First, the FDA just took action to regulate calorie labeling in chain restaurants. Second, colleagues just published yet another peer-reviewed paper probing the mysterious depths of the enigmatic calories.

Third, and most important, if your Thanksgiving was anything...

Health for the Holidays? Have Fun!

With this singular season of lofty ideals, crass commercialism, family gatherings, varying religious significance, aeronautical ungulates, indulgent torpor and culinary debauchery- euphemistically known as "the holidays" -- upon us, where should health figure in it?

At the front of the line, I say. Have a good time!

Public Health as Political Prisoner

(5) Comments | Posted November 18, 2014 | 7:36 PM

If a foreign government took the United States Surgeon General hostage, I'm confident we'd be pretty upset. I think we would be working on reprisals, and maybe even prepping a SEAL team.

I don't know if it's better or worse that we need no help from a foreign power...
