WHO: ‘Very Serious’ Ebola Situation in Eastern DRC

Violence in the eastern Democratic Republic of Congo is hampering efforts to contain an Ebola outbreak that has already killed more than 150 people, according to the World Health Organization.

“It’s a very serious situation. This is something that we have been fearing from the beginning; that the security situation will influence the response to the level that we cannot really function fully,” says a WHO spokesman, Tarik Jasarevic.

The outbreak in Congo’s North Kivu province is in a conflict zone where dozens of armed groups operate.  Aid agencies have been forced to suspend or slow down their work on several occasions since the outbreak began in July.

Health workers killed

It happened again over the weekend, when two health agents with Congo’s military were killed by rebels.  The next day, residents in the city of Beni pelted aid groups’ vehicles with stones during a protest against a separate rebel attack that killed at least 13 people. 

Jasarevic tells VOA’s English-to-Africa service that the incidents have forced Ebola containment teams to severely curtail their operations. The result?  

“Contacts will not be followed; this is something that has to be done on a daily basis. People who may develop the disease will not go immediately to treatment centers and will present danger to their environment,” he says.

Containment delayed

That means health workers will have to essentially start over to locate contacts of Ebola victims and ensure they are vaccinated. 

“In case we are not able to access communities, if in case response measures are not being put in place  safe burials, contact tracing, vaccinations, provision of treatment to those who are sick — it is really difficult to hope that the Ebola outbreak can be contained on its own,” Jasarevic says.

Latest numbers

According to the WHO’s most recent report, released Tuesday, a total of 238 confirmed and probable Ebola Virus Disease cases have been reported in Congo’s North Kivu and Ituri provinces.  It said 155 people have died.

The WHO has warned the virus could spread to nearby countries, such as Uganda, Rwanda and Burundi.

“Neighboring countries need to be ready in case the outbreak spreads beyond the Democratic Republic of the Congo,” said the latest WHO report.

West Africa’s Ebola Outbreak Cost $53 Billion: Study

An Ebola outbreak that ravaged Sierra Leone, Guinea and Liberia in 2014 cost economies an estimated $53 billion, according to a study in this month’s Journal of Infectious Diseases.

The study aimed to combine the direct economic burden and the indirect social impact to generate a comprehensive cost of the outbreak, which was the worst in the world.

The outbreak ran from 2013 to 2016 and killed at least 11,300 people, more than all other known Ebola outbreaks combined. The vast majority of cases were in Guinea, Liberia and Sierra Leone.

The report’s authors, Caroline Huber, Lyn Finelli and Warren Stevens, put the economic costs at $14 billion and said the human cost was even greater, based on the people affected and a dollar figure that reflects the value of each human life.

The total is far higher than previous estimates. In October 2014, the World Bank said the Ebola epidemic could cost $32.6 billion by the end of 2015 in a worst case scenario, but by November 2014 it dialled back that forecast to $3-4 billion. In 2016 the World Bank estimate of economic loss was $2.8 billion.

The 2003 severe acute respiratory syndrome (SARS) cost an estimated $40 billion, while the 2015-2016 Zika virus outbreak in the Americas was estimated to have caused $20 billion in social costs, the new study said.

But a repeat of the 1918 influenza pandemic could cost an annual 700,000 lives and $490 billion, the authors said, citing research published in 2016.

The new Ebola study factored in the impact on healthworkers, long-term conditions suffered by 17,000 Ebola survivors, and costs of treatment, infection control, screening and deployment of personnel beyond West Africa.

The biggest cost not previously accounted for was deaths from other diseases, as Ebola tied up healthcare resources and hospital admissions fell dramatically, adding $18.8 billion to the total bill.

During the outbreak there were 10,623 additional deaths from HIV/AIDS, tuberculosis and malaria, with 3.5 million additional untreated malaria cases.

Measles caused 2,000-16,000 extra deaths as 1 million children missed being vaccinated for measles, and 600,000-700,000 missed other vaccines.

But the authors added that they had limited information on the cost of deploying international health staff and military personnel, and they were obliged to place a value on human life, a widely accepted economic measurement.

Although the “value of a statistical life” (VSL) in North America and Europe is estimated at $7 million-9 million, the authors said, they took a figure from the only study in a West African context, with a VSL of $577,000 in Sierra Leone.

Indonesian Village Bans 3 HIV+ Orphans From School

Authorities in a North Sumatra village have banned three HIV+ orphans from elementary school, and threatened the children, who are from outside the area, with expulsion from Nainggolan due to community fears of transmission.

The children, a boy and two girls, aged 7 to 11 years, were infected by transmission from their mothers, Berlina Sibagariang, executive secretary of the Batak Protestant Christian Huria AIDS Committee (HKBP), told VOA Indonesia. The orphaned children attended preschool and the Nainggolan State Primary School in North Sumatra for one day before they were expelled, in response to outcry from students and parents who learned of their HIV status, according to Sibagariang.

“We want those three children to enjoy their rights to go to school and get an education,” Sibagariang said, adding “the community hopes that the children will no longer attend local schools. They are afraid that their children will be infected with HIV.”

The children were removed from classes on October 22, and Sibagariang said the local community set an October 25 deadline for the children to leave the village.

While an estimated five million people are infected with HIV in Asia, the rate of new infections has slowed in the last decade. But not in Indonesia, which now has an estimated 660,000 people living with HIV, according to the UNAIDS. According to the U.N. agency, Indonesia had 48,000 new HIV infections and 38,000 AIDS-related deaths in 2016, an increase in AIDS-related deaths of 68 percent from 2010. As of 2016, an estimated 3,200 Indonesian children were infected with HIV due to mother-to-child transmission.

There is, Indonesians activists note, ignorance of HIV and its transmission.

“Many people in our rural area still don’t really know what HIV/AIDS is, or the regulations covering it,” Puta Elvina, commissioner of Indonesia’s National Commission to Protect Children (KPAI) told VOA. In Nainggolan, “the school should educate the [Parent Teachers Association (PTA)] about HIV/AIDS so they know they don’t have to worry about it. [The PTA} should communicate to them how people become infected, how HIV is transmitted, etc. And the school has an obligation to those HIV-kids, to protect and support them. Actually not only the school, but also the local people (to support the kids) and the local government.”

Human immunodeficiency virus (HIV) can only be transmitted from an infected person to another through direct contact of bodily fluids such as blood (including menstrual blood), semen, vaginal secretions and breast milk, according to the San Francisco AIDS Foundation, a leading U.S. source of information on HIV and AIDS. “Blood contains the highest concentration of the virus, followed by semen, followed by vaginal fluids, followed by breast milk. … It is possible for an HIV-infected mother to transmit HIV before or during birth or through breast milk. Breast milk contains HIV, and while small amounts of breast milk do not pose significant threat of infection to adults, it is a risk for infants.”

The shunning behavior in Nainggolan is not unique. “HIV stigma is effectively universal, but its form varies from one country to another, and the specific groups targeted for AIDS stigma vary considerably,” says the University of California, Davis. “Whatever its form, HIV stigma inflicts suffering on people and interferes with attempts to fight the AIDS epidemic.”

Tiqoh, who has only one name, is an activist at Yayasan Pelita Ilmu (YPI), a non-governmental organization with a long track record on HIV/AIDS education in Indonesia, understands the difficulty of talking about HIV “with the local people, but perhaps the school could also involve doctors from the local clinic. Those parents and local people who refuse to take care these kids, or don’t want them to study in the same class as their children, they’re taking these actions because they don’t know much about HIV/AIDS. They’re just worry that their kids might be infected.”

HKBP is continuing talks with local government officials and the community as the Thursday deadline approaches in an attempt to stop expulsion of the children from Nainggolan.

“They said that we should remove those children because the local government hasn’t issued a permit to send children to those schools or even stay in that village,” said Sibagariang. “In fact, the home in that village – where we sent the children – is our home, an HKBP home. They have right to stay there.  It’s our home!”

Local leader, Samosir Regent Rapidin Simbolon, told VOA that the HKBP hospital in Nainggolan once “accommodated the elderly, but now they accommodate children who are exposed to HIV.”

So far, the talks have resulted in a suggestion to homeschool the children but the HKBP AIDS Committee rejected this option, saying it would isolate the children and paper over what they see as the real issue: misunderstanding of HIV-AIDS.

 

The committee criticized another local leader, Samosir Deputy Regent, Juang Sinaga, who called for the children to be expelled from the village, and sent to the jungle.

Rapidin told VOA “I am responsible,” he said. “I will not allow the public to directly shun them. … We will protect (the children) so no one will take advantage of the situation. Be assured we are protecting them, we will even involve the police, if necessary. I guarantee that the children are being monitored.”

But the regent said that there were different opinions about the orphans–parents don’t want their children in classes with the HIV+ orphans, “while HKBP who said that [separating these children] is discriminating against HIV-people.”

“The HKBP does not want to understand us,” Rapidin said. “The three children who are positive are not from our region. They come from outside. We are actually very tolerant, it’s OK here. But they (HKBP) are insistent. The HKBP cannot insist like that. Nainggolan residents also have rights.”

Anugerah Andriansyah reported from North Sumatra, Indonesia and Eva Mazrieva reported from Washington, D.C.

Child Death Toll Hits 7 in Viral Outbreak at NJ Rehab Center

Another child has died following a severe viral outbreak at a New Jersey rehabilitation center for “medically fragile children,” bringing the death toll to seven, the facility said Wednesday.

There have been 18 cases overall of adenovirus at the Wanaque Center for Nursing and Rehabilitation in Haskell, about 30 miles (50 kilometers) northwest of New York, the state Health Department said. The 227-bed, for-profit facility cares for children and elderly residents.

The agency had said Tuesday six children had died this month. But the center said it learned Tuesday night that another child had died.

The strain afflicting the children is usually associated with acute respiratory illness, according to the Centers for Disease Control and Prevention, which on its website instructs health workers to report unusual clusters to state or local health departments.

The Health Department hasn’t released the names or the ages of the victims.

The CDC is providing technical assistance to the state. In the past 10 years, cases of severe illness and death from the type of infection found at the facility have been reported in the United States, though it’s unclear how many deaths there have been.

The center’s website says it helps educate “medically fragile children.” The facility was instructed not to admit new patients until the outbreak ends, and the Health Department said the number of new cases appears to be decreasing.

3 Endemic Countries Hold the Key to a Polio-Free World

As another World Polio Day comes around, the World Health Organization reports three polio endemic countries— Afghanistan, Pakistan and Nigeria — hold the key to the global eradication of this crippling disease.   

About one-half million children were becoming paralyzed by polio every year when the World Health Organization began its global polio eradication campaign three decades ago.  Today, that number has been reduced by more than 99 percent.  

WHO reports fewer than 30 cases of the disease this year, many of them in countries that had been considered polio-free. Spokesman for the Polio Eradication Initiative Oliver Rosenbauer tells VOA outbreaks have occurred in Niger, Democratic Republic of Congo, Somalia, Kenya and Papua New Guinea.

“This really, really underscores the risk that we have this disease — that it will continue to reappear, reemerge in areas that have already eradicated this disease.  We see this time and again,” said Rosenbauer. “It is not the first time that we are facing new outbreaks again and we are confident, we know what it takes to stop these outbreaks again.” 

Rosenbauer says these countries are implementing emergency measures to stop the outbreak.  But, he warns the risk of the wild polio virus spreading across borders will continue until the disease is eradicated in the three endemic states of Afghanistan, Pakistan and Nigeria.

“These three countries hold the key to a polio-free world,” said Rosenbauer. “They have been battling this disease so very long, but they are making actually tremendous progress this year.  Never before have we seen the disease in these countries at such low levels as we are today, this year.” 

Rosenbauer says Afghanistan and Pakistan have each reported six cases of polio. 

He says no cases of the paralytic disease have been detected in Nigeria.  But that, he says, does not mean there are no new cases of the disease there.

He notes the wild polio virus is present in parts of Borno State in northeastern Nigeria, which are under the control of Boko Haram militants.  This, he says makes it too dangerous for health workers to conduct disease surveillance to see whether the virus is circulating.

Desperate & Duped? GoFundMe Means Big Bucks for Dubious Care

People seeking dubious, potentially harmful treatment for cancer and other ailments raised nearly $7 million over two years from crowdfunding sites, a study found.

Echoing recent research on campaigns for stem cell therapies, the findings raise more questions about an increasingly popular way to help pay for costly, and sometimes unproven, medical care. 

Soliciting money on GoFundMe and other sites eliminates doctors, hospitals, insurance companies and other “gatekeepers” that can be a barrier to expensive treatment, said lead author Dr. Ford Vox, an ethicist and brain injury expert at Shepherd Center rehabilitation hospital in Atlanta. He calls it “the democratization of economic power through social media” but says it can pose an ethical dilemma.

Online fundraising “has a big bright side” when it helps patients pay for legitimate care, he said. “Communities are really being able to rally around people in rough times. That’s fantastic, but there is this very clear dark side” when treatments sought are worthless or even dangerous.

His study was published Tuesday in the Journal of the American Medical Association. 

GoFundMe says campaigns for medical care are increasing and are among the most numerous on its site. They include solicitations for conventional treatment and for unproven alternative therapies.

“We always encourage people to fully research whatever it is they are raising money for and to be absolutely transparent on their GoFundMe page, so donors can make an informed decision on what they’re donating to,” GoFundMe said in an emailed statement.

The researchers examined campaigns posted from November 2015 through mid-December 2017, mostly on GoFundMe. They focused on five treatments sought in about 1,000 campaigns: homeopathy or naturopathy for cancer; hyperbaric oxygen for brain injuries; stem cells for brain or spinal cord injuries; and long-term antibiotics for persistent Lyme disease.

While some patients swear they’ve benefited from some of the treatments, there is no rigorous scientific evidence that any of them work for the conditions involved, the researchers said.

The most numerous were solicitations for homeopathy or naturopathy for cancer — 474 requests seeking more than $12 million. About one-quarter of that was raised.

Homeopathic products typically contain heavily diluted drugs, vitamins or minerals said to promote healing, although some have been found to contain toxic amounts. Naturopathy, another alternative medicine practice, sometimes uses homeopathic products, herbs and dietary supplements or body cleanses.

Michelle Drapeau has raised about $7,000 on GoFundMe for homeopathy and other alternative remedies since being diagnosed with advanced stomach cancer in February 2017. The 45-year-old investment banker from West Palm Beach, Florida, credits them with keeping her alive since she stopped chemotherapy over a year ago.

“I wanted to make sure I explored every and all options,” Drapeau said. “It’s vital for everyone to have that opportunity.”

Dr. Leonard Lichtenfeld, the American Cancer Society’s deputy chief medical officer, said it’s important to consider what may drive some patients to turn to unproven remedies. U.S. health care costs are exorbitant and many patients run out of money trying to pay them.

And despite considerable progress against cancer and other illnesses, conventional treatment can’t cure every patient, he noted.

“We should not be judgmental and come out and say this is terrible,” Lichtenfeld said.

“No one wants to hear, ‘You have cancer,’ and especially no one wants to hear that there’s no treatment available that can help you,” he said. “You begin to understand why people may turn to unproven treatments and you can understand why others reach out to try to support them.

“What we need to do is to better inform, even better care for our patients and their families, so they don’t feel this is what they need to do.”

Researchers Discover Microplastics in 100 Percent of People Studied

In the first study of its kind, Austrian researchers have tracked the movement of microplastics into human beings. The results show that the plastic that is a ubiquitous element of human life is now also a constant element in the human body.

The research was presented at this week at UEG Week in Vienna, Austria, the largest gastroenterology meeting in Europe.

Follow the plastics

Two Austrian researchers, Dr. Philipp Schwabl from the Medical University of Vienna, and Dr. Bettina Liebmann, from the Environment Agency Austria, studied  participants from countries including Finland, Italy, Japan, the Netherlands, Poland, Russia, the UK and Austria.

Microplastics are particles of plastic less than 5 mm in size. They are often tiny plastic beads that are put in cosmetic products. A few nations, including the U.S., the UK and South Korea, have banned microbeads. But microplastics also are created when larger pieces of plastic break down over time, and plastic in general is everywhere. The U.N. estimates that about 8 million metric tons of plastic end up in the world’s oceans every year. And the World Economic Forum estimated that Americans threw away over 33 million metric tons of plastic in 2014.

But this study, which was small, suggests that plastic, whether it’s bad for us or not, is already in all of us.

Study participants were asked to keep a food diary for seven days prior to taking part in the test. Then they turned over stool samples to the researchers who then looked for microplastics.

And they found them. Every single stool sample tested positive for the presence of microplastic, and up to nine different plastic types were identified.

Where is the plastic coming from? In the cases of this study, the plastic that showed up in people is associated with eating plastic wrapped foods, and drinking from plastic bottles. But most of the participants also ate fish, so Schwabl says that right now, “no exact conclusion on plastic origin can be made” on exactly where the plastic is coming from. Future studies should narrow that down.

What is it doing to us?

So is all that plastic making us sick?  Schwabl says, for now, there are no definitive studies that suggest a danger to humans. But he says that in “animal studies, it has been shown that microplastics may cause intestinal damage, remodeling of the intestinal villi, distortion of iron absorption and hepatic stress.”

And the concern is “what this means to us, and especially patients with gastrointestinal diseases,” Schwabl says. “While the highest plastic concentrations in animal studies have been found in the gut, the smallest microplastic particles are capable of entering the blood stream, lymphatic system and may even reach the liver.”

He was surprised, he says, to find that plastic is apparently showing up in all of us, and he expects the amount collecting in our bodies to keep increasing, unless the world drastically changes its use of plastic.

Christie’s Auctioning Hawking’s Items

Several possessions of the late physicist’s Stephen Hawking will be included in an upcoming auction at Christie’s, the famed auction house.

Included among the items belonging to the iconic scientist will be one of his wheelchairs, one of five copies of his Cambridge University Ph.D. thesis “Properties of Expanding Universes,” and a script from one of his appearances on the television show “The Simpsons.”

At age 22, Hawking was diagnosed with amyotrophic lateral sclerosis, or ALS, just as he was beginning his doctoral work at Cambridge.

Thomas Venning, head of books and manuscripts at Christie’s, said Hawking was so despondent over the diagnosis that he “gave up his studies for a time.”

Hawking, however, returned to school, Venning said, and his thesis “was the fruit of his reapplying himself to his scientific work.” Hawking kept his thesis beside him for the rest of his life, according to Venning.

Hawking was one of the few scientists who have reached celebrity status. He is probably best known for his best-selling book “A Brief History of Time” and for his appearances on “The Simpsons.”

His daughter Lucy said the auction gives “admirers of his work the chance to acquire a memento of our father’s extraordinary life in the shape of a small selection of evocative and fascinating items.”

The physicist’s children hope to preserve his scientific archive.

The Associated Press reports that Christie’s is handling negotiations to hand over the archive to British authorities in lieu of inheritance tax.

Hawking’s items will be featured in a science sale that also includes papers by Isaac Newton, Charles Darwin and Albert Einstein.

Hawking’s items will be on display for several days in London, beginning October 30.

Hawking died in March at age 76.

Typhus Cases Rise in Los Angeles, Several Other US Cities

Typhus, a bacterial infection that is sometimes life threatening, is on the rise in Los Angeles and several other U.S. cities. Public health officials say homelessness is making the problem worse and that the disease, which is associated with poverty and poor sanitation, is making a comeback in the United States.

Los Angeles County has seen 64 cases of typhus this year, compared with 53 at the same point last year and double the typical number, with a six-case cluster among the homeless in L.A. this year. Two cities in the county that have separate counts are also seeing higher numbers: Long Beach with 13 cases, up from five last year, and Pasadena with 20, a more than three-fold increase from 2017.

At a clinic in the L.A. neighborhood called Skid Row, Dr. Lisa Abdishoo of Los Angeles Christian Health Centers is on the lookout for symptoms. 

“It’s a nonspecific fever,” she said, “body aches, sometimes a headache, sometimes a rash.”

This kind of typhus is spread by fleas on rats, opossums, or even pets and is known as murine typhus, from the Latin word for “mouse.”

The risk is higher when people live on the streets in proximity to garbage, but the disease seems to be spreading through the Southern United States.

Not the typhus of WWI

“It’s never been considered a very common disease,” said Peter Hotez, dean of the National School of Tropical Medicine at Baylor College of Medicine in Houston, “but we seem to see it more frequently. And it seems to be extending across from Southern California all along the Mexican border into southeastern Texas and then into the Gulf Coast in Florida.”

Texas had 519 cases last year, said spokeswoman Lara Anton of the Texas Department of State Health Services. That’s more than three times the number in 2010, with clusters in Houston and Galveston. No figures for this year have been released.

This is a separate disease from typhoid fever and is not the epidemic form of typhus that caused hundreds of thousands of deaths in war time. That type, called epidemic typhus, is carried by body lice and often spreads in conflict zones. It led to millions of deaths in World War I alone.

Flea-borne typhus, the kind seen in California and Texas, is serious but often clears up on its own and responds to an antibiotic, Abdishoo said.

“It seems to get better a little faster if you have the treatment,” she said. “But there are cases where people have had more severe complications — it’s rare, but getting meningitis, and even death,” she cautioned.

Migration, urbanization, climate change

The reason for increased typhus numbers is uncertain, but it may be linked to migration, urbanization and climate change, said Hotez, the disease specialist. In some parts of the world, typhus is still linked to war and instability, “in the conflict zones in the Middle East, in North Africa, Central Asia, East Africa, Venezuela, for instance with the political instability there,” he said.

Murine typhus is one of several diseases on the rise in the southern United States, Hotez said. 

“Others include dengue, now emerging in southern Texas and Florida, the Zika virus infection, Chikungunya. We have a huge problem with West Nile virus,” he added, and Chagas disease, a condition usually seen in Latin America.

A report in May from the U.S. Centers for Disease Control and Prevention found that such “vector-borne” diseases, transmitted by ticks, fleas or mosquitoes, more than doubled in the United States between 2004 and 2016.

Hotez says they are on the rise in many industrial nations with crowded cities and pockets of poverty.

Skid Row physician Abdishoo says flea-borne typhus is still uncommon on the streets of Los Angeles, but “it has us all on high alert for this illness that we don’t necessarily think too much about. We want to be vigilant,” she added, “when you see a communicable disease on the rise.”

Officials in Los Angeles say they are working toward housing for the county’s 53,000 homeless residents to relieve conditions that help give rise to typhus and other diseases. Voters approved funding in 2016 and 2017 to finance the efforts.

Public Trust in Vaccines Plummets After Philippines Dengue Crisis

The ability to fight any future outbreaks of disease could be at risk, following a huge loss of public confidence in vaccines in the Philippines. That’s according to a new report from the London School of Hygiene and Tropical Medicine. The drop in trust could also affect the rollout of future vaccination programs, and researchers say the case of the Philippines holds lessons for other countries trying to tackle deadly diseases, as Henry Ridgwell reports.

Immunotherapy Shows Modest Progress Against Breast Cancer

For the first time, one of the new immunotherapy drugs has shown promise against breast cancer in a large study that combined it with chemotherapy to treat an aggressive form of the disease. But the benefit for most women was small, raising questions about whether the treatment is worth its high cost and side effects.

Results were discussed Saturday at a cancer conference in Munich and published by the New England Journal of Medicine. 

Drugs called checkpoint inhibitors have transformed treatment of many types of cancer by removing a chemical brake that keeps the immune system from killing tumor cells. Their discovery recently earned scientists a Nobel Prize. Until now, though, they haven’t proved valuable against breast cancer.

In the study

The new study tested one from Roche called Tecentriq plus chemo versus chemo alone in 902 women with advanced triple-negative breast cancer. About 15 percent of cases are this type, their growth is not fueled by the hormones estrogen or progesterone, or the gene that Herceptin targets, making them hard to treat.

Women in the study who received Tecentriq plus chemo went two months longer on average without their cancer worsening compared with those on chemo alone, a modest benefit. The combo did not significantly improve survival in an early look before long-term follow-up is complete.

Failed protein test

Previous studies found that immunotherapies work best in patients with high levels of a protein that the drugs target, and the plan for the breast cancer study called for analyzing how women fared according to that factor if Tecentriq improved survival overall.

The drug failed that test, but researchers still looked at protein-level results and saw encouraging signs. Women with high levels who received the combo treatment lived roughly 25 months on average versus about 15 months for women given chemo alone.

That’s a big difference, but it will take more time to see if there’s a reliable way to predict benefit, said Dr. Jennifer Litton of the MD Anderson Cancer Center in Houston. She had no role in running the study but enrolled some patients in it and oversees 14 others testing immunotherapies.

“We’re really hopeful that we can identify a group of women who can get a much bigger and longer response,” she said.

Another breast cancer specialist with no role in the study, Dr. Michael Hassett at Dana-Farber Cancer Institute in Boston, said he felt “cautious excitement” that immunotherapy may prove helpful for certain breast cancer patients.

Side effects and cost

Side effects need a close look, both doctors said. Nearly all study participants had typical chemo side effects such as nausea or low blood cell counts, but serious ones were more common with the combo treatment and twice as many women on it stopped treatment for that reason.

Three of the six deaths from side effects in the combo group were blamed on the treatment itself; only one of three such deaths in the chemo group was.

Cost is another concern. Tecentriq is $12,500 a month. The chemo in this study was Celgene’s Abraxane, which costs about $3,000 per dose plus doctor fees for the IV treatments. Older chemo drugs cost less but require patients to use a steroid to prevent allergic reactions that might interfere with the immunotherapy. Abraxane was chosen because it avoids the need for a steroid, said one study leader, Dr. Sylvia Adams of NYU Langone Health.

The study was sponsored by Roche and many study leaders consult or work for the company or own stock in it.

Life in America’s Northernmost Observatory: Tracking Climate Change

An observatory in Barrow, Alaska, part of the National Oceanic and Atmospheric Administration, has become a key scientific instrument in studying climate change. Established in 1973, the Barrow Observatory is staffed year-round by two researchers who measure and track changes in air quality and weather. Natasha Mozgovaya traveled to Barrow, Alaska, now officially called Utqiagvik, its original Inupiaq name, to see what life is like in one of the coldest and snowiest places in the world.

Wet and Mild: Warm Winter Predicted for Much of US

Winter looks wet and especially mild for much of the country, thanks to a weak El Nino brewing, U.S. meteorologists said.

The National Weather Service on Thursday predicted a warmer than normal winter for the northern and western three-quarters of the nation. The greatest chance for warmer than normal winter weather is in Alaska, the Pacific Northwest, Montana, northern Wyoming and western North Dakota.

No place in the United States is expected to be colder than normal, said Mike Halpert, deputy director of the government’s Climate Prediction Center.

The Southeast, Ohio Valley and mid-Atlantic can go any which way on temperature, Halpert said.

Overall the winter looks a lot like the last few, Halpert said.

“The country as a whole has been quite mild since 2014-2015,” Halpert said.

Winter weather expert Judah Cohen, of the private company Atmospheric and Environmental Research, uses different indicators to predict winter for the National Science Foundation. He also forecasted a warm winter, heavily based on weak snowfall in Siberia.

Precipitation 

Halpert said the southern one-third of the United States and much of the East Coast could be hunkering down for a wetter than normal December through January. The chances are highest in southeastern Georgia and much of northern and central Florida.

Hawaii, Montana, Michigan, parts of Idaho, Wisconsin, northern Illinois, Indiana and Ohio are forecast to be drier than normal, with the biggest likelihood in Hawaii, Montana and Michigan.

The middle belt of the nation and some of the north from California to New York can go any which way on precipitation.

The weather service’s forecast doesn’t look at snow likelihood.

El Nino

Halpert said the biggest factor in the forecast is a likely El Nino , the natural warming of parts of the central Pacific Ocean that influences weather worldwide.

The El Nino hasn’t quite formed yet, but it’s almost warm enough. Meteorologists predict there’s a 75 percent chance it’ll be around this winter. But it will be weak, not strong like the El Nino that helped lead to the record warm 2015-2016 winter, Halpert said.

Background warming

While El Nino is the biggest factor in the forecast, long-term warming from human-caused climate change is a factor, too, Halpert said.

“All things being equal, the slight kick we get out of the climate signal does tilt things toward the warm side,” Halpert said.

But it’s not enough to outweigh other factors if they push toward cold.

“Even on a warming planet,” he said, “it doesn’t mean winter goes away and it’s never cold again.”

In Toothy Prequel, Piranha-Like Fish Menaced Jurassic Seas

You can call it a prehistoric prequel.

Scientists said on Thursday they have unearthed in southern Germany the fossil of a fish that, with its mouth full of razor-sharp teeth, strongly resembled today’s piranhas, the stars of more than their fair share of Hollywood horror films. But this one lived during the Jurassic Period 152 million years ago.

Named Piranhamesodon pinnatomus, it is the earliest known example of a bony fish — as opposed to cartilaginous fish like sharks — able to slice flesh rather than simply swallowing prey, enabling it to attack victims larger than itself as piranhas can.

Piranhamesodon, about 3-1/2 inches (9 cm) long, lived in the sponge and coral reefs of the Solnhofen archipelago, a shallow tropical sea in what is now Bavaria. Piranhas are freshwater fish that inhabit rivers and lakes in South America.

Piranhamesodon was small, but its mouth was worthy of a scary movie. It boasted long, pointed, dagger-like teeth along the outer edge of its upper jaw and at the front of its lower jaw. It also had triangular teeth with serrated cutting edges on the side of its lower jaw.

“We were stunned that this fish had teeth which are capable of slicing flesh. It comes from a group of fishes, the pycnodontids, that are famous for their crushing teeth,” said paleontologist Martina Kölbl-Ebert of the Jura-Museum Eichstätt in Germany, who led the research published in the journal Current Biology.

“It is like finding a sheep with a snarl like a wolf,” Kölbl-Ebert added.

The fossil came from the same Bavarian limestone deposits as Archaeopteryx, the earliest-known bird.

“From the same quarry, we also have a number of other fish which may have been the victims of Piranhamesodon. They show injuries to their fins and fin bases, some freshly wounded before they died and got fossilized, whereas others show completely healed injuries with regeneration of the fin,” Kölbl-Ebert said.

While it shares traits with piranhas, Piranhamesodon was neither their long-ago ancestor nor related to them at all. The oldest-known piranhas lived around 15 million years ago.

Piranhamesodon is an example of a phenomenon called convergent evolution in which organisms independently acquire similar characteristics as a result of adapting to similar ecological niches or environments.

“The new fish is a most interesting example of convergent evolution, evolving — for bony fish then — a completely new way of life,” Kölbl-Ebert said.

Uganda, at ‘Big Risk’ for Ebola, Says Congo Is Managing Well

A senior health official in Uganda says “the situation is being handled well” in neighboring Congo after the World Health Organization said the latest Ebola outbreak there is not yet a global emergency.

But Uganda’s director of health services, Henry Mwebesa, tells The Associated Press that twice-weekly market days during which 10,000 Congolese cross into Uganda have put the country at “big risk.”

 

He says unofficial border crossing points also are a cause for concern.

 

This outbreak of the highly infectious Ebola virus in northeastern Congo has killed 107 people.

 

Mwebesa says 222 suspected cases of Ebola have been identified and isolated in Uganda but none have tested positive. He says travelers arriving from Congo are screened for a high body temperature.  

 

Uganda has had five Ebola outbreaks since 2000.

Magnets Might Become Miracle Cure for Pain

The traditional way for doctors to treat certain illnesses has been to prescribe medications. But as technology advances, researchers are working on new ways of treating symptoms that do not require drugs. One promising possibility: using tiny magnetic particles to treat pain. VOA’s Elizabeth Lee visited one lab at the University of California, Los Angeles, to find out how they work.

WHO: Ebola in DRC Is Not a Global Health Emergency

An emergency committee convened by the World Health Organization has decided that the Ebola outbreak in eastern Democratic Republic of the Congo does not constitute a public health emergency of international concern.

The WHO said Wednesday that 216 cases of Ebola and 139 deaths had been reported, and its International Health Regulations Emergency Committee said the outbreak was a matter of serious concern, especially since it is occurring in an area of conflict in eastern DRC. It said this posed problems for health workers who need to move around freely and track people who are infected with the virus and need treatment.

But the committee said that one reason it did not regard the outbreak as a global threat was that the virus had not spread into neighboring countries.

Committee Chairman Robert Steffan said the international response to the outbreak had been very good. He said WHO and other agencies had achieved quite a lot since the outbreak was declared Aug. 1. In fact, he said the disease was being brought under control in North Kivu province.

The disease is flaring up in another province, and the response is being concentrated in this area, he said, “so we do have some optimism that this outbreak, just like the one in May, will be brought under control within reasonable time.”

Steffan said the committee agreed that declaring an international emergency at this time would hinder efforts to contain the Ebola virus. He said a declaration would have implications for travel and trade, making it difficult for needed experts and supplies to access the affected areas.

However, as a precaution, WHO recommended exit screenings, including at airports, ports and land crossings. But it noted that entry screenings, particularly in distant airports, would have no public health benefit and would be costly.

WHO advised DRC’s nine neighboring countries that they were at high risk of having the disease spread into their territories, and it said it was supporting them with equipment and personnel. It said these preparedness activities were expensive and would require substantial financial support from the international community.

UN Report: Reproductive Rights Influence Family Size

Family size is closely linked to reproductive rights, according to the State of World Population 2018 report.

The U.N. report says people in developed countries tend to have lower fertility rates because of greater access to family planning services, modern contraceptives and age-appropriate sex education.

The director of the U.N. Population Fund office in Geneva, Monica Ferro, says in places where reproductive rights are constrained, either due to lack of resources or government mandates, people have a limited ability to choose the size of their families.

“Many sub-Saharan African countries, for example, have fertility rates of four or more births per woman,” Ferro said. “At the other end of the spectrum, you have some eastern Asian and European countries with fewer than two births per women. In both cases, individuals face obstacles to the full realization of their reproductive rights.” 

The world population is expected to increase by 2.5 billion by 2050, to nearly 10 billion people, with sub-Saharan Africa expected to contribute more than half of that growth. 

Women in Africa must overcome many legal and social barriers to achieve control of their fertility, Ferro said.

“Women may not have the access to medical services,” she told VOA. “They may not have the access to child care. They may not have access to all the institutional and social support that comes with being ready or being able to plan your fertility.” 

To make freedom of choice a reality, the report urges countries to offer universal access to quality reproductive health care, including modern contraceptives and better education.

It also advocates for a change in men’s attitudes toward a woman’s right to choose the number, timing and spacing of children.

Modified Cotton Could Be Human Food Source After US Green Light

U.S. regulators have cleared the way for farmers to grow a cotton plant genetically modified to make the cottonseed edible for people, a protein-packed potential new food source that could be especially useful in cotton-growing countries beset with malnutrition.

The U.S. Department of Agriculture Animal and Plant Health Inspection Service on Tuesday lifted the regulatory prohibition on cultivation by farmers of the cotton plant, which was developed by Texas A&M University scientists. The plant’s cottonseed cannot be used as food for people or as animal feed yet in the United States because it lacks Food and Drug Administration approval.

Cotton is widely grown around the world, with its fiber used to make textiles and the cottonseed used among other things to feed animals such as cattle and sheep that have multiple stomach chambers. Ordinary cottonseed is unfit for humans and many animals to eat because it contains high levels of gossypol, a toxic chemical.

With financial help from a cotton industry group, scientists led by Texas A&M AgriLife Research plant biotechnologist Keerti Rathore used so-called RNAi, or RNA interference, technology to “silence” a gene, virtually eliminating gossypol from the cottonseed. They left gossypol at natural levels in the rest of the plant because it guards against insects and disease.

“To me, personally, it tastes somewhat like chickpea and it could easily be used to make a tasty hummus,” Rathore said of gossypol-free cottonseed.

After cottonseed oil, which can be used for cooking, is extracted, the remaining high-protein meal from the new cotton plant can find many uses, Rathore said.

It can be turned into flour for use in breads, tortillas and other baked goods and used in protein bars, while whole cottonseed kernels, roasted and salted, can be consumed as a snack or to create a peanut butter type of paste, Rathore added.

If all of the cottonseed currently produced worldwide were used for human nutrition, it could meet the daily protein requirements of about 575 million people, Rathore said.

Other countries would have to give regulatory approval for the new cotton plant to be grown, though U.S. regulatory action often is taken into consideration.

The new cottonseed’s biggest commercial use may be as feed for poultry, swine and farmed aquatic species like fish and shrimp, Rathore said.

Many of the world’s roughly 80 cotton-producing countries, especially in Asia and Africa, have populations that face malnutrition that could be addressed with the new plant, Rathore added.

Mystery Illness Causing Paralysis in Children Baffles Doctors

Federal and state health officials are baffled by a mysterious and rare illness that seems to target children, causing paralysis.

As of Tuesday, 62 cases of what doctors are calling acute flaccid myelitis have been confirmed in 22 states. Sixty-five suspected cases are being investigated.

“There is a lot we don’t know about AFM and I am frustrated that despite all of our efforts, we haven’t been able to identify the cause of this mystery illness,” Nancy Messonnier, a top official at the Centers for Disease Control, said Tuesday.

What is known about the illness is that more than 90 percent of the confirmed cases are in children 18 years old or younger. The average age of patients is 4.

Victims generally suffer from muscle weakness and some paralysis of the face, neck, back, arms and legs. The paralysis sets in about a week after the children have come down with fever and respiratory illness.

There is no specific treatment, and most of the victims recover. But the long-term effects are still unknown.

Messonnier called it a “pretty dramatic disease.”

Health experts have ruled out some causes, including poliovirus and West Nile virus.

But what is particularly confounding doctors is that the number of cases spikes only every other year — with larger numbers in 2014, 2016 and this year — and fewer cases in 2015 and 2017.

Parents are urged to have their children take basic precautions, such as washing hands and using insect spray to ward off mosquito bites. Doctors are also urging that vaccines be kept up to date.

Any child experiencing weakness or loss of muscle tone in the arms and legs should be examined immediately.
