A New Tick-Borne Illness, and a Plea to Consider the Insects

September 5, 2012 By Maryn Leave a Comment

A tick’s mouth parts under 40x magnification.

In the summer of 2009, two men from northwest Missouri showed up at Heartland Regional Medical Center in St. Joseph, tucked up against the Kansas border 50 miles north of Kansas City. The men were seriously sick. They had high fevers, fatigue, aches, diarrhea and disordered blood counts: lower than normal amounts of white blood cells, which fight infection, and also lower than normal platelets, cells that control bleeding by helping blood to clot. But they had none of the diseases that were high on the differential diagnosis, the list of possible causes that doctors work their way down as they try to figure out what has gone wrong: no flu, no typhus, no Clostridium difficile, and none of the serious foodborne illnesses — no Salmonella, no Shigella, and no Campylobacter.

The two men had one thing in common, though: About a week before being hospitalized, each remembered, he had been bitten by a tick.

CDC: First Death From "State Fair Flu"

August 31, 2012 By Maryn Leave a Comment

The Centers for Disease Control and Prevention today reported the first death from influenza A H3N2 variant (H3N2v), the swine flu strain that has been crossing intermittently from pigs to humans since last year. The victim was an “older adult with multiple underlying health conditions,” according to the CDC, and the Associated Press fills in that the victim was a 61-year-old woman from “central Ohio’s Madison County [who] died this week… after having contact with hogs at the Ross County Fair.” In a statement, the Ohio Department of Health says that she was one of 102 cases so far in the state this year. In total, the CDC says, there have been 289 cases so far this year (with Indiana leading, at 138 cases); in 2011, there were 12. Fifteen people have been hospitalized.

Superbug Summer Books: Experiment Eleven

August 26, 2012 By Maryn Leave a Comment

In the history of antibiotics, the creation myth is the discovery of penicillin. In 1928, Alexander Fleming leaves a window open in his laboratory, a breeze blows across his culture plates, and when he returns to retrieve the plates for cleaning, he discovers that tiny specks of mold that have landed on the plates have killed the staph he had been culturing. The mold is Penicillium, and the compound it produces, once refined and reproduced in a laboratory, launches what we think of as the antibiotic era, and changes medicine forever.

But while penicillin jumpstarts antibiotic production, it is another antibiotic — streptomycin — which arguably creates the pharmaceutical industry, by being the first antibiotic to be patented. (The original penicillin never was, due to complications of timing, and also to its developers’ conviction that it belonged to the world.)

The story of the discovery of streptomycin is much less well-known than that of penicillin. But it ought to be much better-known — because as longtime journalist Peter Pringle recounts in a new book, “Experiment Eleven: Dark Secrets Behind the Discovery of a Wonder Drug” (Walker), it contains so much that is so relevant today, not just to the process of drug discovery, but to the conduct of research. If you care about fairness or justice, Pringle’s account of how graduate student Albert Schatz, the actual identifier of the drug, was deprived of recognition — and a fortune in royalties — will enrage you. If you are a junior scientist, I suspect it will give you nightmares.

The 'NIH Superbug': This Is Happening Every Day

August 24, 2012 By Maryn Leave a Comment

I mentioned in my last post that I’ve been away on assignment and have been trying to catch up to an onslaught of news. One of the things that broke while I was gone was a new paper in Science Translational Medicine describing the ferocious impact on a hospital at the National Institutes of Health of the arrival of carbapenem-resistant Klebsiella pneumoniae, known for short as KPC or CRKP.

Even though the news is now several days old — the paper went live at noon Wednesday and has been covered in most major media since — I think it’s worth doubling back to take a closer look. Because, with all respect to my media colleagues, I think some of this week’s stories have omitted the larger context. So, a different kind of post for me — less news, more analysis, based on this book, this magazine story, and these past posts on antibiotic resistance. Here we go:

Diseases, Cities And The Coming Crowded Future

August 22, 2012 By Maryn Leave a Comment

I’ve been away on assignment, and while I was gone, wow: Suddenly a ton of public important public health news. While I catch up, a quick placeholder, on the importance of cities to the spread of disease.

Recently I was in Dublin, where I gave a talk at the Science Gallery as part of their summer-long, city-wide, interactive and generally fantastic Hack the City celebration. My theme was this:

CDC: Pretty Much Everyone Is Fat

August 13, 2012 By Maryn Leave a Comment

The Centers for Disease Control and Prevention has released its latest mapping of obesity in the United States, based on data gathered by a CDC project known as BRFSS for the Behavioral Risk Factor Surveillance System. The BRFSS is a massive, continuous telephone survey of adults in U.S. states and territories, and every year it churns out high-quality information on a vast array of public health issues: smoking, heart disease, arthritis, asthma, immunization coverage, cancers, diet…. For anyone interested in health data, it’s a huge resource.

The current dive into the data for 2011 finds, unsurprisingly but depressingly, that a significant proportion of the U.S. population is obese. Not just overweight: obese. From the report:

[O]besity prevalence ranged from 20.7% in Colorado to 34.9% in Mississippi in 2011. No state had a prevalence of obesity less than 20%. 39 states had a prevalence of 25% or more; 12 of these states had a prevalence of 30% or more: Alabama, Arkansas, Indiana, Kentucky, Louisiana, Michigan, Mississippi, Missouri, Oklahoma, South Carolina, Texas, and West Virginia.

Superbug Summer Books: FULL BODY BURDEN

August 12, 2012 By Maryn Leave a Comment

I started my journalism career as a projects reporter, working on the kind of investigations that involve sitting in windowless rooms for weeks digging through stacks of old documents. One of the investigations I worked on was the ugly history of the Fernald Feed Materials Production Center outside Cincinnati, a 1,000-acre site near the Indiana border that was one of the links in the manufacturing chain for nuclear weapons after the Manhattan Project made them possible. The plant had been run with a sloppiness that seemed incredible — over the years, millions of pounds of uranium had literally vanished up its smokestacks and into the air and groundwater — and residents of the rural area  were convinced it was responsible for what seemed to be an unusually high rate of cancers nearby.

One of the striking things about their stories was how often they admitted they hadn’t known what was going on at Fernald. The water tower was painted with a red-and-white checkerboard, a little like the logo for Purina, and between that and the facility’s uninformative name, the neighbors had gotten the idea that the plant made pet food. When they discovered that it was actually enriching uranium to make fuel cores for plutonium-production reactors, they felt betrayed, and enraged enough to sue — and, eventually, win.

I always wondered what how the neighbors could have been so deceived, or so trusting, for such a long time. A new book, “Full Body Burden: Growing Up in the Nuclear Shadow of Rocky Flats” (Crown), answered that for me. Kristen Iversen, who is now the director of the MFA creative writing program at University of Memphis, grew up by the plant where Fernald’s “feed materials” eventually ended up: Rocky Flats, which manufactured the plutonium triggers for nuclear weapons, and which was even more dangerously sloppy than Fernald. (A 1969 fire was damped down just as it risked becoming a criticality that could have destroyed the Denver metro area.)

Resistant Gonorrhea: CDC Says Just One Drug Left

August 9, 2012 By Maryn Leave a Comment

Well, that didn’t take long.

Exactly 6 months after warning, in a major medical journal, that gonorrhea was becoming untreatable by the last two drugs commonly used against it, the Centers for Disease Control has taken one of those drugs off the table, leaving just one antibiotic available to treat the disease.

In a bulletin published today, the public health agency says that data from the national Gonococcal Isolate Surveillance Project shows a high enough percentage of resistance to the oral cephalosporin cefixime that “CDC no longer recommends cefixime at any dose as a first-line regimen for treatment of gonococcal infections.” Instead, it says, physicians should administer a single dose of injectable ceftriaxone, accompanied by some additional oral drugs.

This has been coming for a while, but it is still unnerving news. It means that the entire structure of sexually transmitted disease control in the United States — single doses of drugs given in single outpatient-clinic visits — now hangs on this one remaining drug. If ceftriaxone also becomes ineffective, then STD treatment will instead become a matter of giving drugs by IV: slower, more complicated, more expensive, and likely more difficult to access.

Superbug Summer Books: THE POWER OF HABIT

August 5, 2012 By Maryn Leave a Comment

My morning routine is a problem. I work at home: I stumble downstairs, wave goodbye to the spouse and feed the cat, and browse the overnight news while I’m drinking two very strong coffees. About the end of the first cup, I remind myself that I planned to work out this morning. About the end of the second cup, I surface from email long enough to realize that it is an hour later that I thought, and I have missed my chance.

This happens practically daily. The pattern distresses me; I spend a fair amount of effort trying to dislodge it; I fail.

So you can imagine how I latched onto Charles Duhigg’s book “The Power of Habit: Why We Do What We Do In Life and Business” (Random House). Duhigg is a Times investigative reporter, and his book is a reporter’s book: absorbing, wide-ranging, thorough, deeply sourced, and intelligently analytical about the patterns that people — and organizations and societies — pursue without conscious intent. It is very good, and lots of people think so: The book was published in March and as of this weekend has been on the New York Times’ hardcover nonfiction best sellers list for 19 weeks.

Drug-Resistant Gonorrhea: Not Just A U.S. Problem

August 3, 2012 By Maryn Leave a Comment


If you’ve been reading along, you might remember that in the past year, there has been increasing alarm in the public health community about rising rates of drug-resistant gonorrhea, an almost-beaten sexually transmitted disease that has steadily become resistant to just about all the drugs that can be used against it in the outpatient clinics on which STD control relies. (If you haven’t been reading along, then first, Welcome, and second, here are one two three four posts about the problem.)

Highly resistant gonorrhea — which is to say, gonorrhea that has already become resistant to sulfa drugs, penicillin, tetracycline, and fluoroquinolones such as Cipro, and that is gaining resistance to cephalosporins — first emerged in Japan and over the past decade was carried to the western United States, and then crossed the country. But a recent issue of EuroSurveillance, the journal of the European Centre for Disease Prevention and Control, warns that cases are now increasing in Europe, and exhibiting resistance against the last drug that both worked and was uncomplicated to use.

Is Childhood Pertussis Vaccine Less Effective Than We Thought?

August 1, 2012 By Maryn Leave a Comment


Delicately and cautiously, health authorities in the United States and other countries are beginning to open up a difficult topic: Whether the extraordinary ongoing epidemic of whooping cough, the worst in more than 50 years, may be due in part to unexpected poor performance by the vaccine meant to prevent the disease.

That possibility, captured in several recent pieces of research — one published last night — is being raised so carefully because it might lead vaccine opponents to claim incorrectly that pertussis vaccination does not work. That fear contains a deep irony: The current vaccine, in use for about 20 years, replaced an older and more effective one that went out of use because vaccine critics charged it had too high a rate of side effects.

The International AIDS Conference Returns: So Much Still To Do

July 22, 2012 By Maryn Leave a Comment

A quick Sunday note: At 5 p.m. today, Eastern time, something extraordinary will happen in Washington, D.C. It won’t look like much — just the opening of a big conference in a big convention center — but when the 19th International AIDS Conference begins its opening ceremonies, it will mark the first time in 22 years that the largest international gathering on the epidemic, the centerpiece of research and activism, has been held on US soil.

Twenty-two years is effectively one generation — there are probably people attending the conference who were not born when it was last held in this country — as well as two-thirds of the time this disease has been with us. So I think it’s worth underlining how momentous this is, and how it potentially signals a new moment in the long fight against HIV.

Superbug Summer Books: ZOOBIQUITY

July 22, 2012 By Maryn Leave a Comment

 

In the summer of 1997, I was a newspaper reporter covering the Centers for Disease Control and Prevention, and I heard from a contact at the CDC that a team was headed to Hong Kong to check out an odd case. A 3-year-old boy had died of flu. That was sad, but not notable enough on its own to send premier disease detectives rocketing around the world. What was extraordinary about the boy’s death was its cause: a strain of flu known as H5N1 that had never been seen in humans before, though it was common in birds and had recently killed 4,500 chickens on a Hong Kong farm. By the end of that year, 17 other Hong Kong residents would become infected, five others would die, and to shut down the epidemic, Hong Kong would slaughter every chicken in the territory, 1.4 million of them.

That worked, for a while. But in 2003, H5N1 appeared again. Since then, it has sickened 607 people around the world, killing more than half of them. It has done something else too. H5N1 and the 2009 H1N1 “swine flu” — a much larger epidemic whose toll of illness and death was recently revised sharply upward — introduced to many people the idea that diseases could jump from animals to humans, and be much more dangerous to their new human hosts than to the animals they came from.

Diseases that jump in that manner are called “zoonoses,” and because their effect can be so dramatic, they are the subject of major international tracking projects, not to mention cultural fascination. (For just one example, watch last year’s movie Contagion.) But a new book, “Zoobiquity: What Animals Can Teach Us About Health and the Science of Healing” (Knopf) argues that by viewing animals only as a source of infection, we miss a rich range of illnesses that we have in common with other species and that could broaden our understanding of what affects our health and theirs.

Superbug Summer Books: BEFORE THE LIGHTS GO OUT

July 15, 2012 By Maryn Leave a Comment

When my book “Superbug” came out two years ago, I found myself talking a lot about the international epidemic of antibiotic resistance, how it incrementally crept up on us, and how it became overwhelming to confront. I often found myself comparing antibiotic resistance to climate change, a similarly “slow drip” problem that took a long time to build — and that now feels so complex that anyone who wants to contribute to putting the brakes on can feel as though it’s not possible for any one person to effect change.

Around the time I started writing “Superbug,” I met Maggie Koerth-Baker, now the science editor of BoingBoing; we were in the same writers’ circles in Minneapolis, and we got to be friends. Not long afterward, she started work on a book. (Disclosure: I read and commented on some early drafts.) “Before the Lights Go Out: Conquering the Energy Crisis Before it Conquers Us” (Wiley) has been out since March, and it’s a fantastic read: breezy and clever and at the same time sober, thoughtful and thorough about the complexity of energy generation in the United States, the roadblocks to change, and the possibility of doing things differently.

One of the things I like most about the book — and here’s where climate change comes in — is that Maggie explores how many reasons people have for responding to the energy crisis, and makes clear that people don’t have to believe in the “big idea” of a crisis before they are willing to take action to defuse it. She starts the book, in fact, with a vignette of a man who flatly declares, “Climate change is a lie,” and yet drives a hybrid car and uses only CFL bulbs. That seemed to me an important insight that could be carried over to antibiotic resistance, agriculture — any number of big, tangled policy questions.

Investigation: Drug Resistance, Chicken And 8 Million UTIs

July 11, 2012 By Maryn Leave a Comment

So, there’s this thing. A big project. An investigative project, actually. I’ve been working on it for months, and finally I can tell you about it, because it all just published, in various venues, today.

I’ve been working with a great new group, the Food and Environment Reporting Network — one of the grant-funded journalism organizations that have arisen in the wake of the collapse of mainstream journalism — on an important, under-reported topic. Which is: Over the past decade, a group of researchers in several countries have been uncovering links between the use of antibiotics in chicken production and the rising occurrence of resistance in one of the most common bacterial infections in the world.

Superbug Summer Books: DINNER: A LOVE STORY

July 8, 2012 By Maryn Leave a Comment

I have a small private belief — for which, despite being a science writer, I can produce no data — that much of the complex difficulty of the American food system would vanish if people knew how to cook. When I say “cook,” I don’t mean mimicking “Top Chef” theatrics, or reproducing the transglutaminase excesses of molecular cuisine; I don’t even, particularly, mean carefully following recipes. What I mean, instead, is getting people to a place where they can walk into a store, or into their own pantries, emerge with a handful of ingredients, and make them into a meal.

If people trusted they could feed themselves, without much effort or advance planning, they wouldn’t be so vulnerable to the lure of fast and processed food. And if sales of those diminished, the market for the cheap products of industrial agriculture would diminish too. This I believe.

To trust that you can feed yourself, it helps to know a few techniques and to have developed a feel for some simple kitchen processes: when it’s appropriate to use a saute pan or a stock pot, and how long it takes water to boil. Most of all though I think it requires not being intimidated by the idea of cooking. Which is why I wish anyone who wants to be someone who cooks — but doesn’t quite know how to get there — could read “Dinner: A Love Story” (Ecco). At first glance, it’s a cookbook, based on a blog, by Jenny Rosenstrach, a magazine columnist and editor who lives outside New York City. But really, it’s a memoir, and also a how-to manual: a smart, pragmatic, warm and thoughtful guide to how two young professionals taught themselves to cook, and then taught their two kids to like food, and then organized their lives so that they all convene at a home-cooked meal, almost every day.

Not Your Usual Holiday-Danger Warning: Don't Eat the Grill Brush

July 4, 2012 By Maryn Leave a Comment

See the wires dangling from the tuft of bristles at the lower-right corner of the image? Don’t eat them.

It’s kind of a tradition, on Independence Day, for health journalists to relay warnings from public-health authorities. Wear sunscreen, watch the alcohol, don’t leave kids alone in pools, don’t stick sparklers in your eye — that kind of thing. They are important to say, because they might actually prevent someone getting injured, but they are dully familiar, because we’ve heard them all before.

Here’s one I suspect no one has heard before: Don’t swallow your grill brush, it will puncture your intestine.

News Round-Up: Meat, Superbugs, Denmark And Big Food

I was off-line for a week with family issues, and while I was gone, news broke out. (It senses your absence, news does. This is the real reason why coups and major foodborne outbreaks happen in August.)

So while I dive into the bigger stories that seem to be happening — and get some fun summer stuff lined up — here’s a quick recap of things worth noticing:

"Science: It's a Girl Thing": Lab Barbie, Extra Lipstick

June 22, 2012 By Maryn Leave a Comment

This is a screengrab from the "Science: It's a girl thing!" video. Embed below.

(Update: Mid-afternoon June 22, US time, the video was “made private by uploader” on YouTube, making both video and many derisive comments by women inaccessible. I’ve put a screengrab from it above. Second update: Thankfully the original was mirrored. Embed restored below.)

(Update, June 25: The almost-universal outrage over the video had the desired effect. It has been pulled and replaced with video of actual women doing actual science, and the EC’s spokesperson has acknowledged the original video — the one this post is about — was a mistake.)

 

Sometimes, in journalism, you wake up on a Friday morning, and you think: I am topic-ed out. I have no ideas. What on earth am I going to write about?

I had those thoughts, at dawn today. And so I’d like to thank the European Commission, for choosing today to launch its “Science: It’s a girl thing!” campaign, igniting a storm of utterly justified Internet outrage, and making my Friday much easier than I had any right to expect.

(Seriously: Thanks, guys. And, yeah, pretty certain you’re guys.)

Here’s the back-story. In service of the completely laudable goal of getting more young women interested in science and research careers, the EC commissioned a video that invokes every possible offensive cliche: pink, giggling, short skirts, skyscraper heels, lipstick, lipstick as a writing instrument, makeup, makeup brushes, sexy poses, air kisses, men in white coats sliding their glasses up to get a better look, girls bouncing up and down hugging each other, and models of molecules falling down and breaking because OMG TEH SCIENZ IZ SO HARD.

I may have missed a few. [Read more…]
