Marilyn Christian Gearing

February 14, 2008

A personal note: My cousin, Marilyn Christian Smith Gearing, died last night after fighting lymphoma. She was about 74.

Marilyn was the daughter of my father’s sister, Marion. Her father, Roland Christian, was a minister in the Seventh-Day Adventist Church, who traveled a lot. We saw him and my father’s sister about once a year, when they’d pass through our town. Other than that, we had little contact with my father’s family, and my cousins. (Isn’t that a great name for a preacher, by the way?)

So when I got to know Marilyn when I was an adult (and she about 20 years older than I), she was a constant bundle of surprises. We knew she was a nurse. Found out she was dean of nursing at Loma Linda University. Learned in one visit that she was a pilot once, the better to carry out public health missions for the State of Virginia.

Marilyn retired, and traveled. Taking up where her father left off, she’d drop in on my parents, unexpectedly, every year or so. In my father’s last two years, he was greatly pleased when she and her husband would drop in to sing at his bedside.

No, I didn’t take my own advice and debrief her fully on her life. Our history sources are leaving us. Call one of yours, today: Thank them for their contributions, and write down what you learn.

Some of Marilyn’s exploits were picked up in Loma Linda Nursing in 2003 — it’s in .pdf form, starting on page 16, with the cover photo.

Her husband, Walt, said there is a memorial service scheduled for February 16, 3:00 pm. at the University Church Chapel at 11125 Campus Street in Loma Linda, California.

Seattle Times special on fighting malaria

February 4, 2008

Dr. Bumsted at Biocultural Science and Management alerted me to the Seattle Times’ special section on fighting malaria. The extensive set of articles ran in the newspaper on Friday, February 1, 2008. You can order a copy of the special reports in a separate section here.

Child suffering from malaria. Seattle Times, February 1, 2008

Photo caption from Seattle Times: “Malaria strikes hardest at young children, such as 5-month-old Mkude Mwishehe, who lies comatose in the regional hospital at Morogoro, Tanzania. Babies often die as a result of fever, anemia and brain damage caused when the mosquito-borne parasites destroy blood cells and clog blood vessels.”

Seattle’s news organizations look at malaria in large part because malaria is a target of the Bill and Melinda Gates Foundation.

The package features outstanding photography of malaria-affected Tanzania and Zambia, good interviews, in-depth reporting, good writing, and multi-media presentations that might be suitable for classroom work. The multi-media pieces could be used as examples of what students should be doing with PowerPoint projects.

The Seattle Times’ work on the fight against malaria is a tour-de-force masterpiece of what a newspaper can do to promote the public good. The newspaper demonstrates the heights writers can aspire to. Good on ’em, as Molly Ivins would say.

I have not found a single mention of experts calling for more DDT, as the junk-science purveyors do. There are several attempts to urge DDT by readers in the Q&A session, but the expert malaria fighters are careful with their facts — it’s a real education. Read the articles. The research and the work against malaria pushed by the Gates Foundation is exactly the research and work that DDT-happy advocates frustrate with their political screeds.

Which group does more to save Africans, those who fight malaria as described in The Seattle Times, or those who rail at environmentalists and call for more DDT?


DDT works! (When used carefully, in IVM, and sparingly)

November 20, 2007

Discover Magazine’s site has a solid story on DDT and malaria, “Can a maligned pesticide save lives.” Among other things, the article notes that Rachel Carson was scientifically accurate in her cited concerns that DDT was killing birds, and in fact later research of more than 1,000 peer-reviewed papers has born out her worries, and provided even greater evidence of damage.

Cover of November 2007 Discover Magazine, featuring an article on DDT's continuing use in the fight against malaria, and vindicating Rachel Carson's research citations with regard to injuries to birds.

Cover of November 2007 Discover Magazine, featuring an article on DDT’s continuing use in the fight against malaria, and vindicating Rachel Carson’s research citations with regard to injuries to birds.

The article details how DDT is used in integrated vector management (IVM), where pesticides are sparingly and carefully used to prevent their target pests from evolving resistance and immunity.  DDT’s abuse had bred widespread resistance in mosquito populations in Africa and other malaria-endemic locations, forcing the World Health Organization to abandon its ambitious program to eradicate malaria in a program dependent on DDT working for at least a year.

Steven Milloy and the Usual Suspects and Comrades in Junk Science, in the War on Science at AEI and CEI will start their distortions of the Discover article any moment now . . . three, two, one . . .


Fighting malaria with reason

October 29, 2007

We can beat malaria without DDT; we can’t beat malaria without bednets.

Editorial from BMJ (née British Medical Journal?) points out that bednets really work, and they work better when distributed free of charge.  Nets cost about $5.00 each, but in nations where a good day’s pay is about $1.00, charging for them merely means they won’t be purchased and can’t be used.

Time for Sen. Tom Coburn, R-Oklahoma, and Steve Milloy, to listen to reason, stop bashing Rachel Carson, and start fighting malaria.

Update, February 2009; the original link seems irrecoverable; see also this research, BMJ 2007;335:1023 ( 17 November), doi:10.1136/bmj.39356.574641.55 (published 16 October 2007


History of public health victories in the U.S.

October 19, 2007

I wish U.S. history texts for public schools would invest more in the history of public health practice in the U.S.  Much of our prosperity can be traced to good public health practices — the wide availability of generally safe drinking water, effective systems to remove sewage and garbage, and other work to diminish illness.

So, in quick note form pirated directly from the Centers for Disease Control (CDC) (and because this has been hanging fire in my “to edit” box for way too long), here are some public health achievements I think the textbook editors need to consider for the next editions: 

Ten Great Public Health Achievements — United States, 1900-1999

  • Vaccination
  • Motor-vehicle safety
  • Safer workplaces
  • Control of infectious diseases
  • Decline in deaths from coronary heart disease and stroke
  • Safer and healthier foods
  • Healthier mothers and babies
  • Family planning
  • Fluoridation of drinking water
  • Recognition of tobacco use as a health hazard

More internet friendly version here, with links to articles on each one:

http://www.cdc.gov/od/oc/media/tengpha.htm

Here are the details.

Much more available. Here is a site, with a good section talking about careers in public health (for those career planning courses out there). Here’s a similar, less wowee site from the American Schools of Public Health (ASPH). Ethics issues here.

I include the links — there is no reason you can’t add this to your courses, especially in the sections that meet the standards on discussion of achievements of technology.  Surely these are technological achievements of great merit.


A history of environmental disasters (Day After Blog Action Day)

October 16, 2007

Blog Action Day, 2007: We’re writing about environmental issues.

Blog Action Day 2007

Each January 1 I reflect on one of many forgotten environmental disasters, because it’s a focus of television coverage. Oh, the disaster itself isn’t covered — most often it’s not even mentioned — but it’s there if you know anything at all about it.

The Tournament of Roses Parade.

With the Bowl Championship Series game in town, and thousands of tourists out to see the parade, the games, and other festivities, no one really wants to talk about the why of the Rose Bowl, and the Rose Parade.

But once upon a time, under the sunny skies of southern California, Pasadena hosted a flower industry. Cut flowers were the produce. The Los Angeles Basin around Pasadena produced $1 billion in cut flowers annually by the late 1940s. Partly to promote that industry, local civic movers pushed a festival named to celebrate the flowers, to promote them, to feed local industry. The shtick was this: Parade floats had to be decorated exclusively with flowers and flower petals. What better way to showcase the local agricultural miracle?

Nearly 60 years later, I’ll wager less than 0.1% of the flowers used in the parade come from the Los Angeles Basin.

Air pollution forced the flower growers to move. Air pollution mottled the petals of the roses, browned the daisies, and otherwise spoiled blossoms. The greenhouses, the fields, the entire industry left the area. And today, all that is left is the parade and football game. Parade floats are decorated with flowers imported from Venezuela, Israel, Europe, Hawaii, Mexico, South America and Asia.

And so it goes. Significant upheavals in human activities, prompted by environmental goofs by humans, get shuffled out of the history books, out of our collective consciousness — and as Santayana warned, we repeat them, over and over. Los Angeles is not the only city ever to have suffered from air pollution — there were killer fogs in London and Pennsylvania within a decade after World War II. Surely people learned, no?

Consider Mexico City today. Consider Beijing today.

So I just want to list some environmental disasters that we would be better off, if we remembered them and considered how to avoid them in the future, rather than forget them and be doomed to repeat them.

(I reserve the right to post links and edit this list to add to it, as I find additional information, and as readers may add information in comments.)

Environmental disasters you should know

It’s not an exhaustive list by any means — I wager some of these are new to most readers. I wager some of you can provide better information, and other disasters that I, perhaps, have forgotten. Please, inform us.


Malaria control: Requires health care system improvements

October 13, 2007

WHO’s former malaria expert, John Litsios, notes that controlling malaria requires integrated programs, especially including overhaul of local health care delivery systems.

How to fight malaria – Kenya’s example

August 17, 2007

Kenya has cut malaria by nearly half. Without further comment from me, here’s the news story from Gulf Times, Doha, Qatar, and below that, from a few other sources:

Kenya nearly halves child deaths from malaria

Published: Friday, 17 August, 2007, 01:27 AM Doha Time

NAIROBI: Kenya announced yesterday that it almost halved malaria deaths among small children by using insecticidal nets (INTs), spurring the World Health Organisation (WHO) to advocate free nets for all as it tackles Africa’s deadliest disease.

Health Minister Charity Ngilu said distribution of 13.4mn INTs over the past five years among children and pregnant women had helped curtail infections, a key success against a disease threatening 40% of the world’s population.

“Childhood deaths have been reduced by 44% in high-risk districts, in-patient malaria cases and deaths are falling (and) there are reduced cases at the community level,” she said in a statement.

“For every 1,000 treated nets used, seven children who might have died of malaria are saved.”

Malaria kills 34,000 children under the age of five each year in Kenya, and threatens the lives of more than 25mn of its population of 34mn people, the ministry said.

Children sleeping under INTs in malaria risk areas are 44% less likely to die than those who are not, according to a survey carried out in four districts representing the country’s epidemiological pattern.

The government has distributed 12mn doses of artemisinin-based therapy (ACT), the latest surefire anti-malaria drug cocktail to replace the mono-therapies that had developed resistance.

In addition, some 824,600 houses in 16 epidemic-prone districts underwent indoor spraying this year.
The government and donors spent 4.7bn shillings ($70.2mn) for the campaign, yet the funds were not enough.

Ngilu said the government would freely provide 2mn treated nets annually to ward off mosquitoes at night when they are active, calling on donors to boost the blanket distribution.

“The impact we have seen and the lessons we have learnt through massively distributing INTs, rather than selectively marketing and selling them, will not only benefit Kenya’s children but all Africa’s children,” she said.

In a statement, the WHO said it had abandoned its earlier guideline of targeting only vulnerable groups – under fives and pregnant women – in favour of “making their protection immediate while achieving full coverage”.

“Recent studies have shown that by expanding the use of these nets to all people in targeted areas, increased coverage and enhanced protection can be achieved while protecting all community members.”

WHO chief Margaret Chan said that Kenya’s success “serves as a model that should be replicated throughout ‘malarious’ countries in Africa.”

“This data from Kenya ends the debate about how to deliver the long-lasting nets. No longer should the safety or well-being of your family be based upon whether you are rich or poor,” said WHO’s Global Malaria Programme director Arata Kochi.

Chan and Kochi were deriding the “social marketing” model widely backed by donors of distributing INTs by selling them at subsidised rates, even to vulnerable groups, and raising awareness of their importance.

Although supporting anti-malaria campaigns, public health watchers have chided British and US foreign development agencies for pushing for social marketing in the world’s poorest continent.

The WHO launched a global programme in 1955 to eradicate the disease that has frustrated attempts to create a vaccine owing to its constant mutations.

Using dichloro-diphenyl-trichloroethane (DDT), a powerful insecticide, and the drug chroloquine, the organisation managed to eradicated the disease in the West by the 1960s.

But the programme never got off the ground in the humid and low-lying tropics in sub-Saharan Africa where the disease persisted.

By 1969, the programme collapsed as financing withered in the face of rising poverty, political upheavals and surging opposition to DDT for misuse, not by anti-malaria campaigners, but farmers.

But Kochi said the Stockholm Convention on Persistent Organic Pollutants allowed the use of DDT in endemic countries for “public health only” and Uganda and Malawi were the only African nations keen on the chemical.

Malaria affects more than 1bn people worldwide and kills 1mn – mainly under age five – every year, the vast majority in sub-Saharan Africa. – AFP (Agence France Press) Read the rest of this entry »


Accuracy: A good bias (DDT again)

August 4, 2007

Jay Ambrose retired from editing newspapers, and now writes commentary for the Scripps News chain of papers. Because of his experience in editing, I was suprised to see his commentary from last week which takes broad, inaccurate swipes at environmental groups (here from the Evansville, Indiana, Courier & Press).

Ambrose is victim of the “DDT and Rachel Carson bad” hoax.

His column addresses bias in reporting, bias against Christians, which he claims he sees in reporting on issues of stem cell research, and bias “in favor” of environmentalists, which has resulted in a foolish reduction in the use of DDT. I don’t comment here on the stem cell controversy, though Ambrose’s cartoonish presentation of how federally-funded research works invites someone to correct its errors.

Relevant excerpts of Ambrose’s column appear below the fold, with my reply (which I have posted to the Scripps News editorial section, and in an earlier version, to the on-line version of the Evansville paper).

Fisking “Junk Science’s” campaign FOR the poison DDT, against Rachel Carson: Point #8, mosquito resistance to DDT

June 29, 2007

This is the second in a series of Fisks of “100 things you should know about DDT,” a grotesquely misleading list of factoids about DDT put up a site called JunkScience.com. While one would assume that such a site would be opposed, this particular site promotes junk science. I’m not taking the points in order.The “100 things” list is attributed to Steven Milloy, a guy who used to argue that tobacco use isn’t harmful, and who has engaged in other hoaxes such as the bizarre and false claim that Compact Fluorescent Lightbulbs (CFLs) can pose serious toxic hazards in your home (and therefore, you should continue to waste energy with less efficient bulbs); and to J. Gordon Edwards, a San Jose State University entomologist who, despite being a great entomologist, was a bit of a nut on some political things; Edwards assisted Lyndon Larouche’s group in their campaign against Rachel Carson before his death in 2004. (Did Edwards actually have a role in the development of this list?)

100 things you should know about DDT

Claim #8. Some mosquitoes became “resistant” to DDT. “There is persuasive evidence that antimalarial operations did not produce mosquito resistance to DDT. That crime, and in a very real sense it was a crime, can be laid to the intemperate and inappropriate use of DDT by farmers, especially cotton growers. They used the insecticide at levels that would accelerate, if not actually induce, the selection of a resistant population of mosquitoes.”

[Desowitz, RS. 1992. Malaria Capers, W.W. Norton & Company]

Cover of The Malaria Capers, by Robert S. Desowitz

Cover of The Malaria Capers, by Robert S. Desowitz

This was what Rachel Carson warned about. Indiscriminate use of DDT, such as broadcast application on crops to kill all insect, arthropod or other pests, would lead to mosquitoes and other dangerous insects developing resistance to the chemical. Of course, resistance developed as a result of overspraying of crops has exactly the same result, in the fight against malaria, as overuse in the fight against malaria.  Cover of The Malaria Capers, by Robert S. Desowitz

Worse, such overuse also killed predators of mosquitoes, especially birds. In an integrated pest management program, or in a well-balanced ecosystem, birds and other insect predators would eliminate a large number of mosquitoes, holding the population in check and preventing the spread of malaria. Unfortunately, when the predators are killed off, the mosquitoes have a population explosion, spreading their range, and spreading the diseases they carry.

Assuming Milloy quoted the book accurately, and assuming the book actually exists, this point says nothing in particular in favor of DDT; but it reaffirms the case Rachel Carson made in her 1962 book, Silent Spring. Contrary to suggestions from the campaign against Rachel Carson, she urged that we limit use of DDT to tasks like preventing malaria, around humans, to preserve the effectiveness of DDT and prevent overspraying.

And then, there is this: Milloy doesn’t bother to quote the first part of the paragraph he quotes, on page 214 of Malaria Capers. Here is what the paragraph actually says:

There were a number of reasons for the failure, not least that the anophaline vector mosquitoes were becoming resistant to the action of DDT both physiologically — they developed the enzymes to detoxify the insecticide — and behaviorally — instead of feeding and wall-resting, they changed in character to feed and then quickly bugger off to the great outdoors. [from this point, Milloy quotes correctly]

In other words, the DDT-based campaign against malaria failed because DDT failed; mosquitoes became resistant to it.  DDT’s declining ability to kill mosquitoes is one of the major reasons DDT use plunged after 1963, and continues to decline to no use at all.

To combat the dastardly campaign of calumny against Rachel Carson and science, you should also read: Deltoid, here, here and here, and the rest of his posts on the topic; Bug Girl, here, at least, and here, and the rest of her posts; denialism, here; and Rabett Run, here.
