A novel way to treat malaria

Each year 200-300 million people worldwide are infected by malaria, and 1 million children die. This is why many, most notably Bill Gates, have put their money, efforts and time into finding ways to fight malaria. (It is also why, when I asked for donations for tsunami relief two years ago, one old friend lashed out at me saying money would be better spent fighting malaria.)

There was an interesting AP article on the east African jumping spider, Evarcha culicivora.

A jumping spider in East Africa is known to crave mosquitoes engorged with blood. Now scientists find the spider prefers a particular type of them—mosquitoes infested with the deadly malaria parasite. These predatory spiders could help control the lethal disease, scientists say.

...

In past research, the scientists discovered E. culicivora consistently preferred female mosquitoes that had recently finished a blood meal. The spiders targeted bloodsuckers over non-biting midges (by far the dominant mosquito-sized insect in these habitats), male mosquitoes (which do not suck blood), and female mosquitoes that were fed sugar.

Talk about biological warfare. I wonder if this species could somehow be encouraged to grow in numbers to contain the number of mosquitos that spread malaria.

Greatest medical innovation in last 160 years?

Sanitation.

That's right. Here is an AP article that elaborates on the results of the BMJ poll.

Sanitation "greatest medical milestone since 1840"
Thu Jan 18, 9:27 AM ET

Sanitation was voted the most important medical milestone in the past century and a half on Thursday in a poll conducted by a leading medical journal.

Improved sewage disposal and clean water supply systems, which have reduced diseases such as cholera, was the overwhelming favorite of 11,341 people worldwide who voted in the survey conducted by the British Medical Journal.

It surpassed antibiotics, the discovery of DNA, and anesthesia, which were among the top five milestones in the poll. Participants were asked what they thought was the biggest medical advance since the journal was established in 1840.

"I'm delighted that sanitation is recognized by so many people as such an important milestone," said Professor Johan Mackenbach, of Erasmus University Medical Center in Rotterdam who championed the sanitation choice.

"The general lesson which still holds is that passive protection against health hazards is often the best way to improve population health," he added.

"Clearly, sanitation still plays a vital role in improving public health now and in the future," he said.

Other important milestones recommended for the top prize included the development of imaging techniques, the contraceptive pill, immunology and computers.

London was one of first cities of modern times to seriously tackle the problem of poor sanitation after a British doctor, John Snow, discovered in 1854 that cholera was water-borne and not air-borne as had previously being thought.

Bringing clinics closer to where people work

The NY Times covered a growing trend in primary care -- clinics are opening up in large work facilities, or close to them, and often have all the services one can find at a community clinic as well as a pharmacy.

Frustrated by runaway health costs, the nation’s largest employers are moving rapidly to open more primary care medical centers in their offices and factories as a way to offer convenient service and free or low-cost health care. Within the last two years, companies including Toyota, Sprint Nextel, Florida Power and Light, Credit Suisse and Pepsi Bottling Group have opened or expanded on-site clinics. And many employers are adding or planning to add even more clinics, which were experimented with about 30 years ago but fell out of favor amid questions about their cost-effectiveness.

Today a new wave of clinics is opening, driven largely by a motive that was less of a factor in the past: employers’ desires to reduce their health insurance premiums by taking care of workers before they need to see outside doctors. More than 100 of the nation’s 1,000 largest employers now offer on-site primary care or preventive health services — a number forecast to exceed 250 by the end of the year, according to David Beech, a health benefits consultant. Corporate America’s new in-house medical offices go well beyond traditional occupational health clinics that hundreds of factories have long maintained for job-related injuries and worker’s compensation cases. Employees can now stop by for check-ups, allergy and flu shots, pregnancy tests or routine monitoring for chronic diseases like diabetes and asthma.

This isn't new. It was an experiment that failed in most cases in the 1970s. But that was before "health insurance premiums have soared and many companies have run up big bills at emergency rooms and urgent care centers."

And so, "the corporate clinic has made a comeback. For employees, on-site clinics can mean faster medical attention and lower out-of-pocket costs, since visits are usually free or carry only a small co-payment. Some workers may fret about the privacy of their medical records, but employers say they treat the information carefully and responsibly. Some companies hire outside providers to run the clinics, thus offering an additional privacy firewall."

Employers are hosting these clinics because it means more productivity and lower costs.

For employers, on-site clinics can mean gains in worker productivity and lower health-insurance outlays. “A clinic serving a couple thousand employees can probably save $1.5 million to $2 million a year,” said Mr. Beech, a health care specialist at the Watson Wyatt benefits consulting firm. “Right away, it’s easy to see reduced referrals to hospital emergency rooms and specialist physicians, and a shift away from hospital outpatient doctors to the clinic.” The biggest primary care clinic so far opened Jan. 2 in Texas, when Toyota workers and their families started using a $9 million, 20,000-square-foot medical center alongside a new truck assembly plant in San Antonio.

Unlike most of the new medical offices — which are staffed by nurse practitioners and in some cases a part-time doctor — Toyota’s San Antonio health center has two-full time doctors, a part-time physician, a blood-test lab and an X-ray center. It is “a clinic on steroids,” Mr. Beech said. And yet, even smaller operations, like the one with nurses, a physician’s assistant and a part-time doctor at the midtown Manhattan offices of the investment firm Credit Suisse are drawing praise from many employees.

John Probert, a 42-year-old Credit Suisse foreign exchange trader, recently took a few minutes from his 10-and-a-half-hour work day to pick up a prescription for a throat remedy at the firm’s clinic. He had it filled at a nearby pharmacy. “My throat was just killing me,” Mr. Probert said. The next day one of the clinic’s two nurses, Allison Ain, called to see how he was faring. “I told her I was feeling much better,” he said. “It’s nice to have a human on the other end of the phone that actually cares.”

And he liked the fact that his medical care did not take much of his time. “Instead of doing it on a Saturday,” Mr. Probert said, “you can just hop over next door and get back on the trading floor.” Pepsi Bottling, another sponsor of clinics, is trying to meet the basic health care needs of its 33,000 workers at 46 plants and 264 distribution centers around the country. The company currently has 15 clinics and plans to open 15 more over the next couple of years, according to David Kasiarz, the vice president for compensation and benefits.

The rest of the article "Company Clinics Cut Health Costs" by Milt Freudenheim which ran on January 14th, 2007 is below.

Pepsi Bottling employees are not charged for the services, which include not only allergy shots and prescriptions, but advice on weight loss and smoking cessation. “We think health affects business performance,” Mr. Kasiarz said. “Our drivers and sales people define how customers look at Pepsi Bottling. We need to keep them on the street; we need to keep them well and happy.” The nurses and physician’s assistants who run the Pepsi Bottling clinics are employed by a unit of Johns Hopkins University. “It is important that this is considered independent, ” Mr. Kasiarz said.

Although many companies still run their own clinics, a growing number have been hiring independent vendors. CHD Meridian, a unit of I-Trax, is the largest clinic-outsourcing company; others include Whole Health Management, Comprehensive Health Services and IMC HealthCare. All say they have pending orders from employers for new clinics that will offer primary care and other services. “There has been an evolution in this industry,” said Stuart Clark, executive vice president of Comprehensive Health Services, which operates dozens of traditional on-site clinics. “As the workplace becomes safer through training and safety engineering, our customers have opened access to their clinics for nonwork-related issues like flu shots, chronic disease, weight management and smoking.”

Andrew Scibelli, health benefits manager at Florida Power and Light, said his company estimated that it got back $1.50 for every $1 spent at its three on-site health centers, which are run by Whole Health. That estimate, he said, is based on what the services would cost if provided by doctors under the company’s health insurance, along with a calculation of the value of an employee’s time spent visiting an outside doctor. General Motors, despite continuing its traditional clinics, has put its emphasis on working with local doctors and hospitals to improve the quality of health care in communities like Flint, Mich., where G.M. retirees and their families vastly outnumber the company’s active work force.

Other companies have eliminated primary-care clinics, either because they did not consider them cost-effective or for other reasons. Ford Motor, which used to offer basic health care in the 1950s at its big Rouge plant in Dearborn, Mich., now says it believes that most employees prefer to go to their own doctor for primary care. But the foreign-based auto makers in this country, including Nissan and BMW, which do not have union-negotiated benefits or large numbers of retirees, are embracing the on-site health trend for their work forces. Comprehensive Health Services recently announced plans to provide clinic services at three existing Nissan plants and the company’s new North American headquarters in Franklin, Tenn.

Toyota currently has on-site pharmacies or prescription drug services at 11 plants in the United States. The new San Antonio clinic is meant to serve the 2,000 Toyota employees and 2,100 people working for suppliers as well as their families. The doctors, who will be employees of the contractor CHD Meridian, will emphasize preventive care, said Dan Sieger, a Toyota spokesman.

“We are really excited about this,” he said. Big health insurers say they are closely watching the proliferating clinics, which could potentially pose a competitive threat. A vendor company that runs on-site clinics, for example, could steer patients to its own programs for disease management, say, or smoking cessation, instead of equivalent ones offered by the patient’s health insurer.

Cigna, which runs clinics for its own employees in Bloomfield, Conn., Philadelphia and Phoenix, sees its role as a “partner with both the employer and the clinic provider” to make sure an employee’s doctor is fully aware of the patient’s medical history and health needs, said Tom Richards, a Cigna senior vice president. Brad Fluegel, an Aetna vice president, said the company was talking to its large customers about ways to dovetail its own “wellness” and chronic disease management programs with the companies’ expanding on-site programs.

“There might be even greater savings if a clinic can steer people to lower-cost places for treatment — efficient, high-quality providers — and generic drugs” Mr. Fluegel said. A pharmacy is one of the new features planned by Qualcomm, the wireless technology company based in San Diego. The company, which has operated a heavily used free clinic for its 8,000 workers in San Diego since 1998, is now nearly tripling the space to 4,000 square feet, extending visiting hours and hiring Whole Health.

Qualcomm says it sees the clinics and related health services as a way to retain the loyalty of employees — particularly its thousands of engineers. But of course, for Qualcomm and other big companies, cost considerations are always a primary concern. “Employers are so frustrated with health costs that they are looking for any solution,” said Dee W. Edington, director of the Health Management Research Center at the University of Michigan. “One option is to find ways to take care of people before they get sick.”

Robot in labor!

In South Korea, because of a shortage of pregnant women relative to the number of medical students, robots are being used to teach students how to bring babies into the world according to the AP article "Robot mother helps South Koreans prepare for birth."

Kyunghee University Medical Center in Seoul is the first institution in South Korea to use Noelle, a life-sized robot, and her "newborn" to give obstetric students experience.

"With this simulator training tool, we can conduct not only normal deliveries, but also complicated deliveries such as breech births, Caesarean deliveries," Professor Jung Eui told Reuters Television. "Students can practice in a very realistic situation with this mannequin."
Students regularly crowd around Noelle as she gives "birth." They take turns at monitoring her vital signs and at pulling the "baby" out of her body.


The newborn, also a robot, is equipped with lights on its hands and cheeks to indicate its health -- blue lights mean problems while pink lights signal all is ok.

What was interesting is that this robot must be in use in the US:

Noelle was purchased for $20,000 from Miami-based Gaumard Scientific Co. Inc. in the United States. She was manufactured in 2000 and over 400 units have been sold in the United States.
