Bits and Bites from Around the World > Orangutan applies medication to treat facial wound

 

Orangutan treats facial wound with medicinal plant in documented first



In what scientists are calling a first for any non-human species, a Sumatran orangutan in Indonesia was seen creating and applying a medicinal paste made from local plants to a wound on his face.

According to a newly published study about the observation, scientists witnessed Rakus, an adult male orangutan living in Gunung Leuser National Park, chewing the stems and leaves of a plant called akar kuning into a poultice before applying it to his facial wound.

Akar kuning, an evergreen climbing plant, has anti-inflammatory and antibacterial properties and is commonly used in traditional medicine to treat conditions like dysentery, diabetes and malaria.

Scientists watched on as Rakus applied the plant juices and chewed akar kuning (also called yellow root) to a wound under his right eye for seven minutes until it was fully covered. Rakus also applied more fulsome, and less chewed, leaves to his injury akin to a leafy makeshift bandage.

After using the medicinal plant’s juice on his face, Rakus’ wound healed completely within a month. Scientists reported no signs of infection and said the wound closed within five days. Only a faint scar remains on Rakus’s face, scientists reported.

Though akar kuning is part of the local orangutan diet, the study says the plant is rarely eaten by the primates. With this knowledge, and by witnessing the length of Rakus’ self-treatment, scientists concluded he was intentionally using the plant as medicine.

Rakus’ cheek wound was first noticed on June 25, 2022, the same day he was witnessed applying the medicinal plant. Scientists said they believed he obtained the wound in a fight with another male orangutan. Rakus also had a wound inside his mouth.

Rakus, who is believed to be about 35 years old, is the first animal ever documented using a plant to treat an injury — though other primates have been observed treating wounds using different methods in the past.

From 2019 to 2021, a group of scientists studying chimpanzees in Loango National Park in Gabon witnessed the group of primates self-treating their wounds by chewing up a form of flying insect (the species is unknown) and applying the remnants repeatedly to their wounds.

Aside from wound care, scientists in 2017 reported signs of self-medication among a different group of orangutans in Borneo, who applied medicinal plants to their limbs seemingly to soothe sore muscles and joints.

Chimpanzees in multiple locations around the world have also been observed chewing on the shoots of bitter-tasting plants to soothe their stomachs. Gorillas, chimpanzees and bonobos have been documented swallowing certain rough leaves whole to get rid of stomach parasites.

Scientists say these instances are valuable observations that may better help understand the origins of human medicinal treatments and the shared ancestry of great apes and humans.

Biologist Isabella Laumer, lead author of the study published in the journal Scientific Reports, told the BBC this may have been the first time Rakus used a plant to treat a wound.

“It could be that he accidentally touched his wound with his finger that had the plant on it. And then because the plant has quite potent pain-relieving substances, he might have felt immediate pain relief, which made him apply it again and again,” she said.

Alternatively, Laumer suggested Rakus may have learned the medicinal behaviour from watching other orangutans in his group.

Researchers are now looking for other instances of self-medication among orangutans. Scientists have been observing orangutans in Indonesia’s Gunung Leuser National Park since 1994, but they hadn’t previously seen this behaviour.

Opioids, a Mass Killer We’re Meeting With a Shrug

About as many Americans are expected to die this year of drug overdoses as died in the Vietnam, Iraq and Afghanistan wars combined

For more than 100 years, death rates have been dropping for Americans — but now, because of opioids, death rates are rising again. We as a nation are going backward, and drug overdoses are now the leading cause of death for Americans under 50.

“There’s no question that there’s an epidemic and that this is a national public health emergency,” Dr. Leana Wen, the health commissioner of Baltimore, told me. “The number of people overdosing is skyrocketing, and we have no indication that we’ve reached the peak.”

Yet our efforts to address this scourge are pathetic.

We responded to World War II with the storming of Normandy, and to Sputnik with our moon shot. Yet we answer this current national menace with … a Republican plan for health care that would deprive millions of insurance and lead to even more deaths!

More on President Trump’s fumbling of this problem in a moment. But it’s bizarre that Republicans should be complacent about opioids, because the toll is disproportionately in red states — and it affects everyone.

Mary Taylor, the Republican lieutenant governor of Ohio and now a candidate for governor, has acknowledged that both her sons, Joe and Michael, have struggled with opioid addiction, resulting in two overdoses at home, urgent calls for ambulances and failed drug rehab efforts. Good for her for speaking up.

It should be a national scandal that only 10 percent of Americans with opioid problems get treatment. This reflects our failed insistence on treating opioids as a criminal justice problem rather than as a public health crisis.

A Times investigation published this month estimated that more than 59,000 Americans died in 2016 of drug overdoses, in the largest annual jump in such deaths ever recorded in the U.S. One reason is the spread of fentanyl, a synthetic opioid that is cheap and potent, leading to overdoses.

Another bad omen: As a nation, we’re still hooked on prescription painkillers. Last year, there were more than 236 million prescriptions written for opioids in the United States — that’s about one bottle of opioids for every American adult.

Even with all that’s at stake, there are three reasons to doubt that Trump will confront the problem.

First, Trump and Republicans in Congress seem determined to repeal Obamacare, which provides for addiction treatment, and slash Medicaid. The Congressional Budget Office estimated that the G.O.P. House plan would result in an additional 23 million Americans being uninsured in a decade — and thus less able to get drug treatment. Other, more technical elements of the G.O.P. plan would also result in less treatment.

Second, Tom Price, the secretary of health and human services, last month seemed to belittle the medication treatments for opioid addiction that have the best record, and Attorney General Jeff Sessions still seems to think we can jail our way out of the problem.

Third, Trump’s main step has been to appoint Gov. Chris Christie of New Jersey to lead a task force to investigate opioid addiction. But we needn’t waste more time investigating, for we know what to do — and in any case Christie talks a good game but bungled the issue in his home state.

Among experts, there’s overwhelming evidence of what works best: medication in conjunction with counseling. This doesn’t succeed in every case, but it does reduce deaths and improve lives. It also saves public money, because a result is fewer emergency room visits and inpatient hospital stays. So the question isn’t whether we can afford treatment for all people fighting addiction, but whether we can afford not to provide it.

The bottom line is that we need a major national public health initiative to treat as many Americans abusing drugs as possible, with treatment based on science and evidence. We also need to understand that drug overdoses are symptoms of deeper malaise — “deaths of despair,” in the words of Anne Case and Angus Deaton of Princeton University, stemming from economic woes — and seek to address the underlying issues.

Above all, let’s show compassion. Addiction is a disease, like diabetes and high blood pressure. We would never tell diabetics to forget medication and watch their diets and exercise more — and we would be aghast if only 10 percent of diabetics were getting lifesaving treatment.

Innumerable people with addictions whom I’ve interviewed haunt me. One was a nurse who became dependent on prescription painkillers and was fired when she was caught stealing painkillers from a hospital. She became homeless and survived by providing sex to strangers in exchange for money or drugs.

She wept as she told me her story, for she was disgusted with what she had become — but we as a society should be disgusted by our own collective complacency, by our refusal to help hundreds of thousands of neighbors who are sick and desperate for help.

A Norfolk Doctor Found a Treatment for Sepsis. Now He's Trying to Get the ICU World to Listen.

Dr. Paul Marik is using a new combination of drugs to treat sepsis

among others, a group of Eastern Virginia Medical School students and residents in mid August.

and thiamine to treat sepsis. Stephen M. Katz | The Virginian-Pilot

The patient was dying

Valerie Hobbs, 53, was in the throes of sepsis – an infection coursing through her veins that was causing her blood pressure to tank, her organs to fail and her breathing to flag.

“When you have a person that young who’s going to die, you start thinking, ‘What else can we pull out of the bag?’ ” said Dr. Paul Marik, who was on duty that day in the intensive care unit of Sentara Norfolk General Hospital.

In this case, he reached for Vitamin C.

Marik, chief of pulmonary and critical care at Eastern Virginia Medical School, had recently read medical journal articles involving the vitamin, and decided to order IV infusions of it, along with hydrocortisone, a steroid, to reduce inflammation.

Then, he went home.

The next morning, Hobbs had improved so much she was removed from four different medications used to boost her blood pressure. Her kidney function was better. Her breathing eased.

Three days later, she left the ICU.

That was in January 2016. Today, Hobbs is back at her home in Norfolk.

“At first we thought it was a coincidence, that maybe the stars aligned just right and she got lucky,” Marik said.

Ten days later, another patient, a paraplegic, arrived in the ICU with sepsis, and Marik prescribed the same thing. That patient improved as well.

A third patient, a man so sick with pneumonia he was on a ventilator, also received the treatment. The results were the same.

Marik’s response: “What just happened?”

He suggested changing the protocol for patients who arrived with sepsis. He also added another ingredient to the concoction: thiamine, which is Vitamin B.


At first, doctors and nurses were skeptical

Kathi Hudgins, a critical care nurse for 23 years, confesses she doubted Marik’s idea: “I thought it was too simplistic.”

Soon, she was sold.

“We started having patient after patient have these remarkable results,” she said. “They’d be at death’s door and 24 to 48 hours later, they had turned around. We have seen patients walk out of here we didn’t think would leave. To see them turn around so quickly was nothing short of amazing.”

They started tracking the numbers, comparing them with patients who came through the ICU with sepsis the previous year.

A study published online in December by CHEST, an American College of Chest Physicians medical journal, revealed the results:

In 47 patients with sepsis treated in Norfolk General’s ICU, four died in 2016, an 8 percent mortality rate. Of those four, none died of sepsis but rather the conditions that led to sepsis in the first place. The previous year, 19 of 47 septic patients died, a 40 percent mortality rate.

Medical residents started calling the concoction “miracle juice.” Marik dubbed it “the cure for sepsis.”

Kurt Hofelich, Norfolk General’s president, said the protocol is being rolled out to other ICUs in the health system to validate the findings.

“We hypothesize that this new treatment will evolve into a national best practice and a new standard of care for patients with sepsis in an ICU level of care environment,” Hofelich said in a prepared statement released today.


Sounds like a game-changer – but hold on

Dr. David Carlbom, an associate professor of pulmonary critical care at the University of Washington, advises caution.

First, it’s what is called a retrospective study, which means it compares something at one point in time to a control group further back in time.

Second, the numbers are small.

Third, the cases were all at one hospital.

Those are called study limitations. The gold standard study is a randomized, double-blind, placebo-controlled study in which patients with the same condition are observed in the same period, and health care providers don’t know who is receiving the treatment or a placebo.

Carlbom said multiple sites would ensure there was nothing particular to Norfolk that was making a difference.


Marik agrees

He wants there to be a comprehensive study, and he said that Stanford University has expressed some interest. But he said it will be difficult to fund because it uses drugs that have been on the market for decades: “We are curing it for $60. No one will make any money off it.”

Studies take money, and that money often comes from pharmaceutical companies.

“By the time it’s done, it could be three years and the number of people who will die of sepsis by that time will be ginormous,” Marik said.

It's reasonable for pharmaceutical companies to not be interested in spending hundreds of thousands of dollars for a full-blown study when it is clear they will never make that money back. Pharmaceutical companies are in the business of making money, not making sick people well.

The money should come from the government and insurance companies both of which will save billions of dollars in very short order. Insurance companies will save enormous amounts of money by reducing treatment costs, hospital stays, and deaths.

Hobbs, who didn’t realize at the time what was going on to treat her ruptured bile duct, now feels fortunate that Marik tried something out of the usual box: “It was good because it saved my life.”


A million people a year

Sepsis occurs in more than 1 million people a year in this country, with 28 to 50 percent dying, according to the National Institutes of Health.

So that's 280,000 to 500,000 people dying every year. If Marik's cure is genuine and drops the death rate to 8%, that will save between 200,000 and 420,000 lives per year.

The condition can stem from a variety of different ailments and has an overwhelming immune response to infection. Natural chemicals released in the body trigger widespread inflammation, which leads to blood clots and leaky vessels. That slows blood flow, damaging the organs by depriving them of nutrients and oxygen.

In the worst cases, blood pressure drops, the heart weakens and the patient goes into septic shock.


Sepsis treatment costs the US $20bn per year

The cost to treat sepsis in the United States has been estimated at $20 billion a year in 2011.

Just as Marik pulled Vitamin C out of his bag to save the woman in January 2016, he pulls out these facts to sell his sepsis treatment to others.

He believes lives could be saved before a larger study is complete. He’s been traveling the country trying to find audiences of critical-care doctors to peddle the idea – Philadelphia, Charlottesville, Long Island, New York and, earlier this week, Seattle.

He’s gotten significant pushback from doctors who say it’s unethical to try before larger studies are done. But he responds that the use is within the limits of what the Vitamin C pharmaceutical label recommends.

“Half think it’s cool and half think this is hooey nonsense. When something is too good to be true, people don’t want to believe it.”

How can it be unethical to try something that has few if any harmful effects while normal treatment is little more than 50% effective. It's not like it's a new drug with unknown side-effects. If it's possible to save hundreds of thousands of lives, it cannot possibly be ethical to ignore the treatment. In fact, it is downright cruel.

Carlbom said since sepsis results from a lot of different conditions, it could be that the combo could help some more than others, and might even be detrimental to particular ailments.

So he understands why doctors will wait for more study. But Carlbom, who describes himself as an early adopter, says he’s started to try it on his own patients.


Lab results

Marik also took the step of having a researcher examine the idea in the lab. He reached out to John Catravas, who studies and teaches on the subject of bioelectrics at Old Dominion University.

Catravas has spent years researching lung function. Of special interest are the lung’s endothelial cells, which form the linings of the blood vessels: “When you have sepsis, the endothelial cells pull away from each other and allow fluid in the lungs.”

He looked at the effect of the Vitamin C, then the steroid, then the two in combination.

It wasn’t one or the other that was doing the trick, but both, almost as though one was holding the door open for the other to do its work in reducing inflammation.

It was a laboratory finding that supported what was happening in the clinical setting, which Marik included in the CHEST publication.

“We can’t both be completely insane,” Marik said.


It's like washing your hands

Marik, who was born and educated in South Africa, is hardly a lightweight in the field. He has more than two decades of critical-care experience and has authored 400 medical journal articles and four books on critical care.

Still, the prospect of the lives this could save excites him at age 58.

Always one to use humor in the practice of medicine and life, Marik takes delight in the story of Ignaz Semmelweis. The Hungarian doctor in the 1840s figured out that doctors doing autopsies were also delivering babies, and unintentionally infecting patients, leading to high mortality rates. Midwives who weren’t doing autopsies had much lower rates.

He advised hand washing with a chlorine solution that acted as a disinfectant. When interns under his direction did that, their maternal mortality rates plunged.

But doctors were furious at Semmelweis, who ended up losing his job. The chlorine hand wash was abandoned.

Semmelweis ended up in a mental institution at age 47, and died there from, by some accounts, sepsis, which he’d worked so hard to try to prevent in women giving birth. His simple advice was picked up again when Louis Pasteur developed the germ theory of disease.

The irony is not lost on Marik:

“People who have studied sepsis a long time don’t want to believe a simple solution can work. Hopefully before I die it will be shown to be true.”

Hopefully, long before that!

Do You Know What Pulmonary Hypertension Is?

You might have it and not know it

May 5th is World Pulmonary Hypertension Day
But November is Pulmonary Hypertension Month

This is a horrible, debilitating and deadly disease
and much too little is known about it


Not well known

Pulmonary Hypertension is a fatal disease that many people have and don't know it. It is not well understood by most family physicians, and they will often diagnose asthma instead. Even some hospitals will refuse to treat a PH'er.

My wife has been on a Facebook group with other PH'ers, and we have lost several of them in the past two years. One of them went to her local hospital in a city of 50,000, and they refused to treat her. They sent her on a 5 hour road trip to the nearest hospital that would treat PH'ers. A few days later she died.

Symptoms

The major symptoms are:

Shortness of breath (dyspnea), initially while exercising and eventually while at rest
Fatigue
Dizziness or fainting spells (syncope)
Chest pressure or pain
Swelling (edema) in your ankles, legs and eventually in your abdomen (ascites)
Bluish color to your lips and skin (cyanosis)

Racing pulse or heart palpitations


What is it

Briefly, it is an increase in blood pressure between your heart and lungs. Left untreated, it can destroy your heart in as little as two years. With treatment, you can survive for another ten to twenty years but life will not be easy. There are no age restrictions that apply to PH; anyone is susceptible.

To find out more about this horrible disease please visit the Mayo Clinic.
