Washington — An array of advanced tests found no brain injuries or degeneration among U.S. diplomats and other government employees who suffer mysterious health problems once dubbed “Havana syndrome, ” researchers reported Monday.

The National Institutes of Health’s nearly five-year study offers no explanation for symptoms including headaches, balance problems and difficulties with thinking and sleep that were first reported in Cuba in 2016 and later by hundreds of American personnel in multiple countries.

But it did contradict some earlier findings that raised the specter of brain injuries in people experiencing what the State Department now calls “anomalous health incidents.”

“These individuals have real symptoms and are going through a very tough time,” said Dr. Leighton Chan, NIH’s chief of rehabilitation medicine, who helped lead the research. “They can be quite profound, disabling and difficult to treat.”

Yet sophisticated MRI scans detected no significant differences in brain volume, structure or white matter — signs of injury or degeneration — when Havana syndrome patients were compared to healthy government workers with similar jobs, including some in the same embassy. Nor were there significant differences in cognitive and other tests, according to findings published in the Journal of the American Medical Association.

While that couldn’t rule out some transient injury when symptoms began, researchers said it’s good news that they couldn’t spot long-term markers on brain scans that are typical after trauma or stroke.

That “should be some reassurance for patients,” said study co-author Louis French, a neuropsychologist at Walter Reed National Military Medical Center who treats Havana syndrome. “It allows us to focus on the here and now, to getting people back to where they should be.”

A subset, about 28%, of Havana syndrome cases were diagnosed with a balance problem called persistent postural-perceptual dizziness, or PPPD. Linked to inner-ear problems as well as severe stress, it results when certain brain networks show no injury but don’t communicate properly. French called it a “maladaptive response,” much like how people who’ve slouched to alleviate back pain can have posture trouble even after the pain is gone.

The Havana syndrome participants reported more fatigue, posttraumatic stress symptoms and depression.

The findings are the latest in an effort to unravel a mystery that began when personnel at the U.S. embassy in Cuba began seeking medical care for hearing loss and ear-ringing after reporting sudden weird noises.

Early on, there was concern that Russia or another country may have used some form of directed energy to attack Americans. But last year, U.S. intelligence agencies said there was no sign a foreign adversary was involved and that most cases appeared to have different causes, from undiagnosed illnesses to environmental factors.

Some patients have accused the government of dismissing their ailments. And in an editorial in JAMA on Monday, one scientist called for more research to prepare for the next such health mystery, cautioning that NIH’s study design plus the limits of existing medical technology could have missed some clues.

“One might suspect that nothing or nothing serious happened with these cases. This would be ill-advised,” wrote Dr. David Relman of Stanford University. In 2022, he was part of a government-appointed panel that couldn’t rule out that a pulsed form of energy could explain a subset of cases.

The NIH study, which began in 2018 and included more than 80 Havana syndrome patients, wasn’t designed to examine the likelihood of some weapon or other trigger for Havana syndrome symptoms. Chan said the findings don’t contradict the intelligence agencies’ conclusions.

If some “external phenomenon” was behind the symptoms, “it did not result in persistent or detectable pathophysiologic change,” he said.

The State Department said it was reviewing NIH’s findings but that its priority was ensuring affected employees and family members “are treated with respect and compassion and receive timely access to medical care and all benefits to which they are entitled.”

CAPE TOWN, South Africa — Mice accidentally introduced to a remote island near Antarctica 200 years ago are breeding out of control because of climate change, and they are eating seabirds and causing major harm in a special nature reserve with “unique biodiversity.”

Now conservationists are planning a mass extermination using helicopters and hundreds of tons of rodent poison, which needs to be dropped over every part of Marion Island’s 297 square kilometers (115 square miles) to ensure success.

If even one pregnant mouse survives, their prolific breeding ability means it may have all been for nothing.

The Mouse-Free Marion project — pest control on a grand scale — is seen as critical for the ecology of the uninhabited South African territory and the wider Southern Ocean. It would be the largest eradication of its kind if it succeeds.

The island is home to globally significant populations of nearly 30 bird species and a rare undisturbed habitat for wandering albatrosses — with their 10-foot wingspan — and many others.

An undisturbed habitat, at least, until stowaway house mice arrived on seal hunter ships in the early 1800s, introducing the island’s first mammal predators.

The past few decades have been the most significant for the damage the mice have caused, said Dr. Anton Wolfaardt, the Mouse-Free Marion project manager. He said their numbers have increased hugely, mainly due to rising temperatures from climate change, which has turned a cold, windswept island into a warmer, drier, more hospitable home.

“They are probably one of the most successful animals in the world. They’ve got to all sorts of places,” Wolfaardt said. But now on Marion Island, “their breeding season has been extended, and this has resulted in a massive increase in the densities of mice.”

Mice don’t need encouragement. They can reproduce from about 60 days old and females can have four or five litters a year, each with seven or eight babies.

Rough estimates indicate there are more than 1 million mice on Marion Island. They are feeding on invertebrates and, more and more, on seabirds — both chicks in their nests and adults.

A single mouse will feed on a bird several times its size.

Conservationists snapped a photo of one perched on the bloodied head of a wandering albatross chick.

The phenomenon of mice eating seabirds has been recorded on only a handful of the world’s islands.

The scale and frequency of mice preying on seabirds on Marion has risen alarmingly, Wolfaardt said, after the first reports of it in 2003. He said the birds have not developed the defense mechanisms to protect themselves against these unfamiliar predators and often sit there while mice nibble away at them. Sometimes, multiple mice swarm over a bird.

Conservationists estimate that if nothing is done, 19 seabird species will disappear from the island in 50 to 100 years, he said.

“This incredibly important island as a haven for seabirds has a very tenuous future because of the impacts of mice,” Wolfaardt said.

The eradication project is a single shot at success, with not even a whisker of room for error. Burgeoning mice and rat populations have been problematic for other islands. South Georgia, in the southern Atlantic, was declared rodent-free in 2018 after an eradication, but that was a multiyear project; the one on Marion could be the biggest single intervention.

Wolfaardt said four to six helicopters will likely be used to drop up to 550 tons of rodenticide bait across the island. Pilots will be given exact flight lines and Wolfaardt’s team will be able to track the drop using GPS mapping.

The bait has been designed to not affect the soil or the island’s water sources. It shouldn’t harm the seabirds, who feed out at sea, and won’t have negative impacts for the environment, Wolfaardt said. Some animals will be affected at an individual level, but those species will recover.

“There’s no perfect solution in these kinds of things,” he said. “There is nothing that just zaps mice and nothing else.”

The eradication project is a partnership between BirdLife South Africa and the national Department of Forestry, Fisheries and the Environment, which designated Marion Island as a special nature reserve with the highest level of environmental protection. It has a weather and research station but is otherwise uninhabited and dedicated to conservation.

The department said the eradication of mice was “essential if the unique biodiversity of the island is to be preserved.”

Wolfaardt said the amount of planning needed means a likely go-ahead date in 2027. The project also needs to raise about $25 million — some of which has been funded by the South African government — and get final regulatory approvals from authorities.

Scientists have tried to control the mice of Marion in the past.

They were already a pest for researchers in the 1940s, so five domestic cats were introduced. By the 1970s, there were around 2,000 feral cats on the island, killing half a million seabirds per year. The cats were eliminated by introducing a feline flu virus and hunting down any survivors.

Islands are critical to conservation efforts, but fragile. The Island Conservation organization says they are “extinction epicenters” and 75% of all species that have gone extinct lived on islands. About 95% of those were bird species.

“This really is an ecological restoration project,” Wolfaardt said. “It’s one of those rare conservation opportunities where you solve once and for all a conservation threat.”

SACRAMENTO, Calif. — California Assemblyman Anthony Rendon likes to spend his spare time away from the Capitol in Sacramento with his 4-year-old daughter at home near Los Angeles. Last weekend, he took her ice skating and afterward to an indoor playground, then let her get a donut after she agreed to ride her scooter on the way there. 

“Those are the types of things that make me happy,” he said this week in an interview outside the state Assembly chambers, where he’s served as a lawmaker for a dozen years. 

Now Rendon, a Democrat who was one of the longest-serving Assembly speakers in California history, is spending his last year in office trying to make happiness more central to policymaking. He created a first-in-the-nation group to study the issue, called the Select Committee on Happiness and Public Policy Outcomes, which held its first public hearing this week. 

It would be “silly” for lawmakers to not study how they can make people happier, Rendon said. 

“Because if we have everybody clothed, everybody housed, everybody has a job and they’re miserable, then we’ve failed at what we’re trying to do,” he said, adding that lawmakers should think about happiness as a priority in policymaking. 

In California, three-quarters of adults say they are “very happy” or “pretty happy,” while 26% say they are “not too happy,” according to a September 2023 survey from the Public Policy Institute of California. Adults aged 18 to 34, people who are renters, those without a post-high school degree, and Californians with an annual household income of $40,000 or lower tend to be less happy than others. 

California is breaking new ground in the United States. At least 12 state legislatures in the nation have committees focused on mental health and substance abuse issues, but no other state legislature has a committee devoted to happiness, according to the National Conference of State Legislatures. 

But the idea to consider happiness in public policy isn’t unprecedented: The landlocked country of Bhutan in South Asia prioritizes happiness as a goal of public policy, measuring it through something written into its constitution called the Gross National Happiness Index. The country surveys residents on their level of happiness, and officials work to increase happiness by providing residents with free health care and education, protecting cultural traditions, and preserving forests, said Phuntsho Norbu, consul general of the Kingdom of Bhutan to the United States. 

The government cannot make every person happy, but it should “create the right conditions that will allow people to pursue happiness,” Norbu said. 

Lawmakers on California’s new committee heard this week from experts about the things that make people happy, what public officials can do to help and what role state and local government can play. The committee isn’t set on any solutions yet but plans to release a report with its findings after lawmakers adjourn for the year at the end of August, said Katie Talbot, Rendon’s spokesperson. 

Assembly member Pilar Schiavo, a Democrat representing part of the San Fernando Valley in Los Angeles County, hopes the committee’s work can address poor mental health among youth in California, which her 11-year-old daughter has told her is a big issue in her class at school. 

“It’s a true crisis that we have on our hands right now,” Schiavo said. “This is really getting to the heart of what that crisis is about.” 

Research demonstrates that leisure activities, social relationships and life circumstances contribute to a person’s happiness, said Meliksah Demir, a professor of happiness at California State University, Sacramento. Public officials can work toward improving happiness by investing in mental health resources, making green spaces more accessible and teaching about the value of happiness early on in schools, Demir said. 

Happiness has wide-ranging benefits that include making people more likely to vote, more creative and healthier, he said. 

The Public Policy Institute of California’s September survey found that 33% of adults overall say they are very satisfied with their job, 31% say they are very satisfied with their leisure activities and 44% are very satisfied with their housing. 

Californians’ level of happiness decreased during the pandemic, but experts are still researching the decline, said Mark Baldassare, the group’s survey director. 

California, which is often ahead of other states on issues such as climate policy and civil rights, is behind many parts of the world in prioritizing happiness in policymaking, Rendon said. He was inspired to create the happiness committee in part by a report on happiness released annually by the United Nations Sustainable Development Solutions Network. 

Last year’s report said that how people view the effectiveness of government — including how well it raises money, delivers services and avoids civil war — can influence their happiness. The United States was 15th in a world happiness ranking based on a three-year average from 2020 to 2022, according to the report. Scandinavian countries, including Finland and Iceland, ranked the highest. 

Rendon’s decision to create the happiness committee aligns with his approach to making state policy that focuses on “bigger picture” social issues, longtime labor lobbyist Kristina Bas Hamilton said. People have different perspectives on government involvement in their lives, but the creation of the committee evokes the ultimate purpose of government, she said.

“Government’s role is to provide for its people,” Bas Hamilton said. “The goal is to have happy citizens. That’s the goal of all public policy.”

NAIROBI, Kenya — Doctors at Kenya’s public hospitals began a nationwide strike Thursday, accusing the government of failing to implement a raft of promises from a collective bargaining agreement signed in 2017 after a 100-day strike that saw people dying from lack of care.

The Kenya Medical Practitioners Pharmacists and Dentists Union said they went on strike to demand comprehensive medical cover for the doctors and because the government has yet to post 1,200 medical interns.

Davji Bhimji, secretary-general of KMPDU, said 4,000 doctors took part in the strike despite a labor court order asking the union to put the strike on hold to allow talks with the government. And Dennis Miskellah, deputy secretary general of the union, said they would disregard the court order the same way the government had disregarded three court orders to increase basic pay for doctors and reinstate suspended doctors.

Miskellah said medical interns make up 27% of the workforce in Kenya’s public hospitals, and their absence means more sick people are being turned away from hospitals. Some doctors, however, have remained on duty to ensure patients in the intensive care units don’t die.

In an interview with broadcaster Citizen TV, Miskellah said doctors were committing suicide out of work-related frustration, while others have had to fund-raise to get treated for sickness due to a lack of comprehensive health coverage.

The impact of the strike was felt across the country with many patients left unattended or being turned away from hospitals across the East African nation.

Pauline Wanjiru said she brought her 12-year-old son for treatment on his broken leg, which had started to produce a smell, but she was turned away from a hospital in Kakamega county in western Kenya.

In 2017, doctors at Kenya’s public hospitals held a 100-day strike — the longest ever held in the country — to demand better wages and for the government to restore the country’s dilapidated public-health facilities. They also demanded continuous training of and hiring of doctors to address a severe shortage of health professionals.

At the time, public doctors, who train for six years in university, earned a basic salary of $400 to $850 a month, similar to some police officers who train for just six months.

Windhoek, Namibia — A top Namibian health official tells VOA the southern Africa country is set to begin distribution of the HPV vaccine to adolescent girls in April as a preventative measure in the fight against cervical cancer.

Namibia has a population of about 1 million women ages 15 years and older who are at risk of developing cervical cancer.

Each year, about 375 women in Namibia are diagnosed with the disease, and the fatality rate is over 50%.

The Human Papillomavirus Vaccine, known as HPV, has been proven to greatly lessen the chance of getting cervical cancer.

Ben Nangombe, executive director at Namibia’s Ministry of Health and Social Services, says health workers will begin vaccinating about 183,000 girls between the ages of nine and 14 next month.

He says the ministry has been allocated $7 million to procure single dose vaccines for this purpose.

Mehafo Amunyela, who works at the #Be Free Youth Program in the capital’s Katutura Township, told VOA that vaccine hesitancy could be a hurdle to fully immunizing the target population. She said she hopes that through awareness campaigns, children and their families can be educated about the advantages of getting the vaccine.

“We saw the reaction of the public toward the COVID vaccine when it came out, but I think we need to be honest with ourselves and remember that the reason we don’t have illnesses like polio is because of vaccines, that they worked then, and they still do now,” she said.

The Cancer Association of Namibia says the vast distances between most towns and villages in Namibia could present another logistical challenge in the immunization program.

The association says to achieve the target of immunizing 183,000 girls, awareness campaigns should be undertaken in the different indigenous languages spoken in the country.

With the rollout of the HPV vaccine, Namibia is on the path to do its part in meeting the World Health Organization’s goal of vaccinating 90% of girls worldwide by 2030, with the long-term goal of eliminating cervical cancer within the next century.

Although cervical cancer is preventable and curable, the disease claimed 350,000 lives worldwide in 2022 according to the WHO.

Washington — A polio survivor known as the “man in the iron lung” has died aged 78, according to his family and a fundraising website.

Paul Alexander of Dallas, Texas contracted polio at the age of six, leaving him paralyzed from the neck down and reliant on a mechanical respirator to breathe for much of the time.

Though often confined to his submarine-like cylinder, he excelled in his studies, earned a law degree, worked in the legal field and wrote a book.

“With a heavy heart I need to say my brother passed last night,” Philip Alexander posted on Facebook early Wednesday. “It was an honor to be part of someone’s life who was as admired as he was.”

Christopher Ulmer, a disability advocate running a fundraiser for Alexander, also confirmed his death in a GoFundMe update posted on Tuesday.

“His story traveled wide and far, positively influencing people around the world. Paul was an incredible role model that will continue to be remembered,” said Ulmer.

A prior update on Alexander’s official TikTok account said he had been rushed to the emergency room after contracting Covid-19.

Iron lungs are sealed chambers fitted with pumps. Raising and lowering the pressure inside the chamber expands and contracts the patient’s lungs.

Invented in the 1920s, their use fell away after the invention of the polio vaccine by Jonas Salk, which became widely available in 1955 and helped consign the devastating paralytic illness to history.

Alexander held the official Guinness World Record for time spent in a lung.

According to his Guinness page, he was able to leave the device for periods of time after he learned to “frog breathe” with the help of a physical therapist.

This involved “using his throat muscles to force air into his lungs, gulping down air one mouthful at a time.” Eventually, he only returned to his iron lung at night to sleep.

As a practicing lawyer, he was able to represent clients in court in a special wheelchair that held his paralyzed body upright.

Seventy-five-year-old Martha Lillard of Shawnee, Oklahoma is reportedly the last surviving person in an iron lung.

UNITED NATIONS — The number of children worldwide who died before age 5 reached a record low in 2022, the United Nations said in a report published Tuesday, as for the first time fewer than 5 million died.

According to the estimate, 4.9 million children died before their fifth birthday in 2022, a 51% decrease since 2000 and a 62% drop since 1990, according to the report, which still warned such progress is “precarious” and unequal.

“There is a lot of good news, and the major one is that we have come to a historic level of under-five mortality, which … reached under 5 million for the first time, so it is 4.9 million per year,” Helga Fogstad, director of health at the U.N. children’s agency UNICEF, told AFP.

According to the report, prepared by UNICEF in conjunction with the World Health Organization (WHO) and the World Bank, progress was particularly notable in developing countries such as Malawi, Rwanda and Mongolia, where early childhood mortality has fallen by more than 75% since 2000.

“Behind these numbers lie the stories of midwives and skilled health personnel helping mothers safely deliver their newborns … vaccinating … children against deadly diseases, and [making] home visits to support families,” UNICEF Executive Director Catherine Russell said in a statement.

But “this is a precarious achievement,” the report warned. “Progress is at risk of stagnation or reversal unless efforts are taken to neutralize the numerous threats to newborn and child health and survival.”

Researchers pointed to already worrying signs, saying that reduction in under-5 deaths has slowed at the global level and notably in the sub-Saharan Africa region.

In total, 162 million children under the age of 5 have died since 2000, 72 million of whom perished in the first month of life, as complications related to birth are among the main causes of early childhood mortality.

Between the ages of 1 month and 5 years, respiratory infections, malaria and diarrhea become the main killers — ailments that are all preventable, the report points out.

To reach the U.N.’s goal of reducing under-5 deaths to 25 per 1,000 births by 2030, 59 countries will need urgent investment in children’s health, researchers warned. And without adequate funding, 64 countries will miss the goal of limiting first-month deaths to 12 per 1,000 births.

“These are not just numbers on a page; they represent real lives cut short,” the report said.

The numbers also reveal glaring inequalities across the world, as the sub-Saharan Africa region accounted for half of all deaths of children under age 5 in 2022.

Babies born in countries with high early childhood mortality, such as Chad, Nigeria or Somalia, are 80 times more likely to die before their 5th birthday than babies born in countries with low childhood mortality rates, such as Finland, Japan and Singapore.

“Where a child is born should not dictate whether they live or die,” WHO head Tedros Adhanom Ghebreyesus said.

Cape Canaveral, Florida — Four astronauts from four countries caught a lift back to Earth with SpaceX on Tuesday to end a half-year mission at the International Space Station.

Their capsule streaked across the U.S. in the predawn darkness and splashed into the Gulf of Mexico near the Florida Panhandle.

NASA’s Jasmin Moghbeli, a Marine helicopter pilot, led the returning crew of Denmark’s Andreas Mogensen, Japan’s Satoshi Furukawa and Russia’s Konstantin Borisov.

They moved into the space station last August. Their replacements arrived last week in their own SpaceX capsule.

“We left you some peanut butter and tortillas,” Moghbeli radioed after departing the orbiting complex on Monday. Replied NASA’s Loral O’Hara: “I miss you guys already and thanks for that very generous gift.”

O’Hara has another few weeks at the space station before leaving aboard a Russian Soyuz capsule.

Before leaving the space station, Mogensen said via X, formerly known as Twitter, that he couldn’t wait to hear “birds singing in the trees” and also craved crunchy food.

NASA prefers multiple travel options in case of rocket trouble. Boeing should start providing astronaut taxi service with a two-pilot test flight in early May.
