Study Raises Questions About Military Service Causing Chronic Suicidal Tendencies

A new study commissioned by the U.S. Army has found that the mental health of soldiers isn’t as different from civilians as the researchers previously thought.

Earlier this year, researchers said that soldiers, who were surveyed at different times during their Army careers, had higher rates of mental disorders before they enlisted than the rates of mental illness in the general population.

Nearly five years ago, during the peak of the H1N1 — swine flu — pandemic, a joke appeared on the Internet based on the nursery rhyme “This Little Piggy.”

The joke (clearly for public health insiders) was intended to comment on the similarities between swine flu and avian flu, and it concluded this way:

And this little piggy went “cough, sneeze” and the whole world’s media went mad over the imminent destruction of the human race, and every journalist found out that they didn’t have to do too much work if they just did “Find ‘bird’, replace with ‘swine’” on all their saved articles from a year ago, er, all the way home.

The punch line makes an important point about the recycling of stories. But for all of its insight into this phenomenon, the joke doesn’t end up taking the lesson far enough.

Because it’s not just the media that recycles stories — it’s all of us.

In “An Epidemic of Rumors: How Stories Shape Our Perceptions of Disease,” I conducted an extensive study of the narratives — the rumors, legends, conspiracy theories, bits of gossip, etc. — that circulated during the H1N1, SARS and AIDS pandemics.

The results showed that all three pandemics were rife with rumors that, though created decades apart, had striking similarities. Every disease had a story claiming a government conspiracy or cover-up. Every disease had a list of surefire cures and treatments “they” don’t want you to know about. Every disease had false and inaccurate stories about where it had spread to and who was infected. Continue reading

Colleges Are Inconsistent In Handling Athlete Concussions, Harvard Study Finds

Colleges remain inconsistent in the way they handle athletes’ concussions, according to a Harvard University study that comes more than four years after the NCAA began requiring schools to educate their players about the risks of head trauma and develop plans to keep injured athletes off the field.

In a survey that included responses from 907 of the NCAA’s 1,066 members, researchers found that nearly one in five schools either don’t have the required concussion management plan or have done such a poor job in educating their coaches, medical staff and compliance officers that they are not sure one exists.

“Collectively, the institutions without a concussion management plan are responsible for the well-being of thousands of college athletes each year,” according to the study co-written by Harvard researcher Christine Baugh and published this week in the American Journal of Sports Medicine. “For stakeholders to follow an institution’s concussion management plan – or to have confidence that others are following the plan – they must first know that it exists.”

The findings in the study reinforce the images fans have seen in stadiums since the problem with concussions became more widely known: Wobbly players are sent back onto the field without proper medical clearance as coaches remain ignorant to their injury – perhaps willfully. The authors recommend that the NCAA bolster its 2010 policy to require schools to make their plans public, to better educate coaches about concussion symptoms and to require that schools not only come up with plans but actually apply them.

E-Cigarette Debate: 7,000 Flavors Of Addiction, But What Health Risks?

I’m not young or edgy enough to hang out with anyone who smokes e-cigarettes, but I’ve been vaguely aware that they’re a big and growing thing, and the focus of a big and growing controversy. To wit: Do they end up a net positive, because they help people quit the classic “cancer sticks,” or a net negative, because they act as “gateway” cigarettes just when we’ve finally beaten our smoking rates down?

Answer: We don’t know yet. That’s my takeaway from a major multimedia project on electronic cigarettes on Boston University’s new research website. But it’s such an important question that it’s even a source of debate between prominent researchers on campus — though both strongly concur that more research is needed. From “Behind The Vapor:”

At Boston University, Avrum Spira, a pulmonary care physician and School of Medicine associate professor of pathology and laboratory medicine and bioinformatics who studies genomics and lung cancer, was one of the first scientists to receive funding from the FDA to investigate the health effects of e-cigarettes. “In theor y—- and how they’re marketed — e-cigarettes are a safer product because they don’t have tobacco, which has known carcinogens,” Spira says. “The question is: does safer mean safe?”

(From the Boston University video)

(From the Boston University video)

Across BU’s Medical Campus from Spira, Michael Siegel, a physician and professor of community health sciences at the School of Public Health, has emerged as perhaps the country’s most high-profile public health advocate for e-cigarettes. Siegel, who is not currently researching e-cigarettes, says he believes that the device could potentially help large numbers of smokers quit, or drastically decrease, a habit that is the leading cause of preventable deaths in the US. He points out that despite all the existing smoking cessation products on the market, only a small fraction of cigarette smokers manage to quit. Only 4 to 7 percent break the habit without some nicotine replacement or medication, according to the American Cancer Society. At the same time, Siegel says, more research is needed on the health effects of e-cigarettes as well as their effectiveness in helping people quit smoking.

Reality Check: How People Catch Ebola, And How They Don’t

It’s confusing. You hear that Ebola victim Thomas Eric Duncan was so contagious that two Dallas nurses in protective gear caught the virus. But then you hear, in more recent days, that apparently nobody else did, including the inner circle who lived with him and cared for him. The CDC announced today that all of Mr. Duncan’s “community contacts” have completed their 21-day monitoring period without developing Ebola.

How to understand that? And how to address alarmists’ claims that for the nurses and so many West Africans to have caught Ebola, it must have gone “airborne”?

I turned to Dr. Elke Muhlberger, an Ebola expert long intimate with the virus — through more than 20 years of Ebola research that included two pregnancies. (I must say I find this the ultimate antidote for the fear generated by the nurses’ infections: A researcher so confident in the power of taking the right precautions that she had no fear — and rightly so, it turned out — for her babies-to-be.)

Dr. Muhlberger is an associate professor of micriobiology at Boston University and director of the Biomolecule Production Core at the National Emerging Infectious Diseases Laboratories (widely referred to as the NEIDL, pronounced “needle”) at Boston University. Our conversation, lightly edited:

Is it really true you worked on Ebola through two pregnancies?

Yes, but in the proper protective gear. That makes a huge difference, if you’re protected, if you know how to protect yourself, and that is the case in a Biosafety Level 4 lab, of course. If you compare the protective gear we’re wearing in a Biosafety Level 4 lab and the gear they’re wearing in West Africa now treating patients, it’s like comparing a stainless steel vault to a cardboard box.

But on the other hand, if you look at the nurses in Dallas, you say, ‘How did they get infected?’ It makes you worry that maybe protective gear isn’t good enough — but you’re proof of the opposite.

A Biosafety Level 4 lab is such a high-end lab, it is not possible to use protective gear like that in every hospital in the U.S.

Could you please lay out a brief primer on the biology of how Ebola is transmitted?

We know from previous outbreaks, and also from the current outbreak, that Ebola is transmitted by having very close contact to infected patients. So we know that it is transmitted by bodily fluids, which include blood, first of all — because the amount of virus in the blood is very, very high, especially at late stages of infection — but it’s also spread by vomit, by sputum, by feces, by urine and by other bodily fluids.

The reason for that is that at late stages of infection, the Ebola virus affects almost all our organs — it causes a systemic infection. One main organ targeted by Ebola virus is the liver, and that could be one of the reasons that we see these very high concentrations of viral particles in the blood. But I would like to emphasize that that occurs late in infection.

Early infection is the other way around. The primary targets — the first cells that come in contact with Ebola virus and get infected — are cells that are part of our immune system. And these cells most likely spread the virus throughout our body. But there are not so many cells infected at the very beginning of the infection, which might be the reason why Ebola virus patients do not spread virus at the very beginning of infection. And that’s why it’s safe to have contact with these patients, because the viral titers in their blood are so low that we cannot even detect them with methods like PCR, which is one of the methods we use to diagnose Ebola virus.

Is a virus only contagious when it reaches a certain level of “titer” or load? Continue reading

Ebola Tipping Point? Dispelling Myths And, Possibly, Less Hysteria Over Virus

Has the national hysteria over Ebola peaked? Who knows. Maybe. There seem to be fewer front page headlines screaming about it; a new national poll finds most Americans are “positive” about the response by public health authorities; and today’s news is that more than 40 Dallas residents (all who had been in contact with the Liberian man who died of Ebola) were declared virus-free.

Still, education is the antidote to hysteria, so it’s worth reiterating some of the facts. Many of them can be found in this must-read commentary in the London Review of Books by Paul Farmer, the rock star Harvard infectious disease doctor and leading advocate for global health equity in the world’s most impoverished regions. Farmer, who is also a co-founder of the Boston non-profit Partners in Health, writes that despite some of the truly scary aspects of the virus, an Ebola diagnosis is not necessarily a death sentence:

The Ebola virus is terrifying because it infects most of those who care for the afflicted and kills most of those who fall ill: at least, that’s the received wisdom. But it isn’t clear that the received wisdom is right….

…the fact is that weak health systems, not unprecedented virulence or a previously unknown mode of transmission, are to blame for Ebola’s rapid spread. Weak health systems are also to blame for the high case-fatality rates in the current pandemic, which is caused by the Zaire strain of the virus. The obverse of this fact – and it is a fact – is the welcome news that the spread of the disease can be stopped by linking better infection control (to protect the uninfected) to improved clinical care (to save the afflicted). An Ebola diagnosis need not be a death sentence. Here’s my assertion as an infectious disease specialist: if patients are promptly diagnosed and receive aggressive supportive care – including fluid resuscitation, electrolyte replacement and blood products – the great majority, as many as 90 per cent, should survive.

And he adds this:

I’ve been asked more than once what the formula for effective action against Ebola might be. It’s often those reluctant to invest in a comprehensive model of prevention and care for the poor who ask for ready-made solutions. What’s the ‘model’ or the ‘minimum basic package’? What are the ‘metrics’ to evaluate ‘cost-effectiveness’? The desire for simple solutions and for proof of a high ‘return on investment’ will be encountered by anyone aiming to deliver comprehensive services (which will necessarily include both prevention and care, all too often pitted against each other) to the poor. Anyone whose metrics or proof are judged wanting is likely to receive a cool reception, even though the Ebola crisis should serve as an object lesson and rebuke to those who tolerate anaemic state funding of, or even cutbacks in, public health and healthcare delivery. Without staff, stuff, space and systems, nothing can be done.

The True Cost Of A Mother’s Death: Calculating The Toll On Children

Walif was only 16 and his younger sister, Nassim, just 11 when their mother died in childbirth in Butajira, Ethiopia.

Both Walif and Nassim had been promising students, especially Walif, who had hoped to score high on the national civil service exam after completing secondary school. But following the death of their mother, their father left them to go live with a second wife in the countryside. Walif dropped out of school to care for his younger siblings, as did Nassim and two other sisters, who had taken jobs as house girls in Addis Ababa and Saudi Arabia.

Nassim was married at 15, to a man for whom she bore no affection, so that she would no longer be an economic burden to the family. By the age of 17, she already had her first child. Seven years after his mother died, Walif was still caring for his younger siblings, piecing together odd jobs to pay for their food, although he could not afford the school fees.

In all, with one maternal death, four children’s lives were derailed, not just emotionally but economically.

More than 1,000 miles away, in the rural Nyanza province of Kenya, a woman in the prime of her life died while giving birth to her seventh child, leaving a void that her surviving husband struggled to fill. He juggled tending the family farm, maintaining his household, raising his children and keeping his languishing newborn son alive.

But he didn’t know how to feed his son, so he gave him cow’s milk mixed with water. At three months old, the baby was severely malnourished. A local health worker visited the father and showed him how to feed and care for the baby. That visit saved the baby’s life.

As these stories illustrate, the impact of a woman’s death in pregnancy or childbirth goes far beyond the loss of a woman in her prime, and can cause lasting damage to her children — consequences now documented in new research findings from two groups: Harvard’s FXB Center for Health and Human Rights, and a collaboration among Family Care International, the International Center for Research on Women and the KEMRI-CDC Research Collaboration.

The causes and high number of maternal deaths in Ethiopia, Malawi, Tanzania, South Africa, and Kenya — the five countries explored in the research — are well documented, but this is the first time research has catalogued the consequences of those deaths to children, families, and communities.

The studies found stark differences between the wellbeing of children whose mothers did and did not survive childbirth:

• Out of 59 maternal deaths, only 15 infants survived to two months, according to a study in Kenya.
• In Tanzania, researchers found that most newborn orphans weren’t breastfed. Fathers rarely provided emotional or financial support to their children following a maternal death, affecting their nutrition, health care, and education.
• Across the settings studied, children were called upon to help fill a mother’s role within the household following her death, which often led to their dropping out of school to take on difficult farm and household tasks beyond their age and abilities.

How to use these new research findings to advocate for greater international investment in women’s health?

Opinion: Why America’s Ebola Fears Are Dangerously Misplaced

At the memorial service last weekend for the only person to have died of Ebola on American soil, the Liberian clergyman who eulogized his countryman Thomas Eric Duncan posed a question we all should be thinking hard about right now.

“Where did Ebola come from to destroy people — to set behind people who were already behind?” Methodist Bishop Arthur F. Kulah wondered.

Here’s the reality: Until the world (and especially the United States of America) refocus on the “people who were already behind” in this battle of virus-versus-humanity, no one can rest easy.

Ebola is an animal virus that has sporadically caused local human outbreaks in Africa for at least 38 years. But now it has crossed into people who live in densely populated African nations with barely functioning health systems and daily jet connections to the rest of the planet.

“It’s like you’re in your room and the house is on fire, and your approach is to put wet towels under the door.”
– World Bank chief Jim Yong Kim

This is entirely predictable, as scientists who watch emerging diseases have long known. They just didn’t know which virus would be the next to terrorize the world. (SARS and HIV showed how it can happen, remember?)

Those of us who, like me, report on global public health have a sense of inevitability as we watch the Ebola crisis unfold. We always knew it would mostly affect, as Bishop Kulah so aptly puts it, “people who were already behind.”

And we knew the people least affected by this scourge — privileged denizens of wealthier countries — would overreact out of misplaced fear for themselves, rather than a reasoned and compassionate understanding about what needs to be done.

So we see the freaked-out, wall-to-wall, feedback-loop media coverage we’re experiencing now. Schools closing down in Ohio for completely unnecessary disinfection. Recriminations against hapless health workers who suddenly find themselves dealing with an exotic new threat. Continue reading
