Who Will Care for Infants With H.I.V. Overseas?
The Trump administration has dismissed the few remaining health officials who oversaw care for some of the world’s most vulnerable people: more than 500,000 children and more than 600,000 pregnant women with H.I.V. in low-income countries.
Expert teams that managed programs meant to prevent newborns from acquiring H.I.V. from their mothers and to provide treatment for infected children were eliminated last week in the chaotic reorganization of the Health and Human Services Department.
Some of the consequences of the dismissals are only now coming to light.
While it was known that some staff members devoted to H.I.V. prevention in other countries had been lost, The New York Times has learned that all such experts have now been terminated or are awaiting reassignment at the Centers for Disease Control and Prevention, the State Department and the U.S. Agency for International Development.
These maternal health programs are still funded by the President’s Emergency Plan For AIDS Relief, or PEPFAR. But without personnel to manage the initiatives or to disburse the money, it’s not clear how the work will continue.
The Health and Human Services Department did not respond to a request for comment.
“We hope this is not a sign that treating mothers and children is no longer important in PEPFAR, and that this is a mistake that can be corrected,” said a federal health official who spoke on condition of anonymity for fear of retaliation.
The stakes are high. Already in sub-Saharan Africa, a child under 15 dies of AIDS every seven minutes.
On Tuesday, a study in The Lancet estimated that suspending PEPFAR could lead to about one million new H.I.V. infections by 2030 and could lead to nearly 500,000 AIDS deaths among children and the orphaning of 2.8 million more.
After the nascent Trump administration froze all foreign aid, Secretary of State Marco Rubio issued a waiver permitting delivery of “core lifesaving medicine, medical services” and other activities funded by the United States.
A waiver specific to PEPFAR later explicitly continued support for programs meant to prevent mother-to-child transmission of H.I.V., and to provide treatment of infected women and children.
The paperwork allowing the aid to resume took weeks after the waiver was issued, and several organizations are only just beginning to receive federal funds required to run the programs.
“You can dismantle something very quickly, but now you’re trying to build it back up with a fraction of the staff and potentially 5 percent of the institutional knowledge,” said a federal official who wasn’t authorized to speak to the news media and requested anonymity.
All experts in pediatric H.I.V. were all let go in the gutting of U.S.A.I.D., leaving a single unit at the C.D.C. with the expertise to advise overseas programs. That team was lost in last week’s reorganization, along with another that handles disbursement of funds for 300 grants in more than 40 countries.
Given the State Department waiver, those layoffs came as surprise to the federal health workers and to the organizations that rely on them.
“We clearly understood that H.I.V. services for mothers and children would fall under” the waiver, said Dr. Anja Giphart, executive vice president of medical and scientific affairs at the Elizabeth Glaser Pediatric AIDS Foundation.
The foundation depends on the C.D.C. for about 60 percent of its budget. “We were totally blindsided that the whole unit at C.D.C. is being terminated,” she said.
The organization has been promised funds until September. But only a few people were authorized to use the payment system at the C.D.C.
“Everyone is scrambling now to figure out how to pay country teams and partners,” said a C.D.C. official who requested anonymity for fear of retaliation.
Other experts said that they were not surprised by the hollowing out of the C.D.C.’s H.I.V. teams despite the waiver.
“What we’ve seen is that there’s no rhyme and reason to any of the actions that the administration is taking,” said Jirair Ratevosian, who served as the chief of staff for PEPFAR in the Biden administration.
Care for children and pregnant women with H.I.V. is complex.
Infants need an H.I.V. test different from the one used for adults, and infected babies must take a separate set of medications. They succumb quickly to complications when treatment is interrupted.
“Especially when you think about children, time is of the essence,” Dr. Giphart said. “That seems to not really be taken into consideration with all these changes that are being made.”
In low-income countries, pregnant women with H.I.V. usually get treatment at prenatal clinics. Without treatment, one in three pregnant women may pass H.I.V. on to her baby.
Treatment decreases the risk of transmission to less than 1 percent. PEPFAR has prevented nearly eight million such infections in newborns since its inception, in 2003.
The foreign aid freeze imposed in January has resulted in shortages of pediatric H.I.V. drugs in many countries and the delayed delivery of a new H.I.V. drug treatment.
The C.D.C. experts who were let go had been helping low-income countries prepare for this transition, tracking stocks and helping to direct the medications to the places with the most urgent needs, said an official who spoke on condition of anonymity for fear of retaliation.
“This coordination is especially critical right now because we’re in a period of immense change,” the official said.

A new study suggests that middle-aged men may be more vulnerable to faster biological aging, potentially linked to exposure to “forever chemicals.”
The research, published in the journal Frontiers in Aging, examined how perfluoroalkyl and polyfluoroalkyl substances, more commonly known as PFAS, could impact aging at the cellular level.
PFAS are synthetic chemicals commonly used in nonstick cookware, food packaging, water-resistant fabrics and other consumer products, the study noted.
Their chemical structure makes them highly resistant to breaking down, allowing them to accumulate in water, soil and the human body.
Chinese researchers analyzed blood samples from 326 adults enrolled in the U.S. National Health and Nutrition Examination Survey between 1999 and 2000.

The researchers measured levels of 11 PFAS compounds in participants’ blood and used DNA-based “epigenetic clocks” — tools that analyze chemical changes to DNA to estimate biological age — to determine how quickly their bodies were aging at the cellular level, the study stated.

Two compounds, perfluorononanoic acid (PFNA) and perfluorooctanesulfonamide (PFOSA), were detected in 95% of participants.
Higher concentrations of those chemicals were associated with faster biological aging in men of certain age groups, but not in women.
“People should not panic.”
The compounds most strongly linked to accelerated aging were not the PFAS chemicals that typically receive the most public attention, the researchers noted.

“The associations were strongest in adults aged 50 to 64, particularly in men,” Dr. Xiangwei Li, professor at Shanghai Jiao Tong University School of Medicine and the study’s corresponding author, told Fox News Digital.
“While this does not establish that PFAS cause aging, it suggests that these widely present ‘forever chemicals’ may be linked to molecular changes related to long-term health and aging.”
The study found that two of the compounds were detected in 95% of participants, and higher levels were linked to faster biological aging in men ages 50–64. (iStock)
Midlife may represent a more sensitive biological period, when the body becomes more vulnerable to age-related stressors, according to the researchers.
Lifestyle factors, such as smoking, may influence biological aging markers, potentially increasing vulnerability to environmental pollutants.
While Li said “people should not panic,” she does recommend looking for reasonable ways to reduce exposure.
That might mean checking local drinking water reports, using certified water filters designed to reduce PFAS, and limiting the use of stain- or grease-resistant products when alternatives are available.

Meaningful reductions in PFAS exposure will likely depend on broader regulatory action and environmental cleanup efforts, Li added.
The researchers noted that midlife could be a particularly sensitive stage, when the body is more susceptible to stressors associated with aging. (iStock)
Study limitations
The researchers outlined several important limitations of the research, including that the findings show an association, but do not prove that PFAS directly causes accelerated aging.
“The study is cross-sectional, meaning exposure and aging markers were measured at the same time, so we cannot determine causality,” Li told Fox News Digital.
The study was also relatively small, limited to 326 adults age 50 or older, which means the findings may not apply to younger people or broader populations.

Researchers measured PFAS levels using data collected between 1999 and 2000, and today’s exposure patterns may differ.
Li added that while PFAS is known to persist in the environment and the body, these results should be validated through larger, more recent studies that follow participants over time.

A drug that has long been used to treat seizures has shown promise as a potential means of Alzheimer’s prevention, a new study suggests.
The anti-seizure medication, levetiracetam, was first approved by the FDA in November 1999 under the brand name Keppra as a therapy for partial-onset seizures in adults. The approval has since expanded to include children and other types of seizures.
Northwestern University researchers recently found that levetiracetam prevented the formation of toxic amyloid beta peptides, which are small protein fragments in the brain that are commonly seen in Alzheimer’s patients.
The medication was found to prevent the formation of amyloid-beta 42 in both animal models and cultured human neurons, according to the study findings, which were published in Science Translational Medicine.
The effect was also seen in post-mortem human brain tissue obtained from individuals with Down syndrome, who are at high risk for Alzheimer’s disease.

“While many of the Alzheimer’s drugs currently on the market, such as lecanemab and donanemab, are approved to clear existing amyloid plaques, we’ve identified this mechanism that prevents the production of the amyloid‑beta 42 peptides and amyloid plaques,” said corresponding author Jeffrey Savas, associate professor of behavioral neurology at Northwestern University Feinberg School of Medicine, in a press release.
“Our new results uncovered new biology while also opening doors for new drug targets.”
HIDDEN BRAIN CONDITION MAY QUADRUPLE DEMENTIA RISK IN OLDER ADULTS, STUDY SUGGESTS
The brain is better able to avoid the pathway that produces toxic amyloid‑beta 42 proteins in younger years, but the aging process gradually weakens that ability, Savas noted.
“This is not a statement of disease; this is just a part of aging. But in brains developing Alzheimer’s, too many neurons go astray, and that’s when you get amyloid-beta 42 production,” he said.
The effect was also seen in post-mortem human brain tissue obtained from individuals with Down syndrome, who are at high risk for Alzheimer’s disease. (iStock)
That then leads to tau (“tangles”) — abnormal clumps of protein inside brain neurons — which can kill brain cells, trigger neuroinflammation and lead to dementia.
In order for levetiracetam to function as an Alzheimer’s blocker, high-risk patients would have to start taking it “very, very early,” Savas said — up to 20 years before elevated amyloid-beta 42 levels would be detected.

“You couldn’t take this when you already have dementia, because the brain has already undergone a number of irreversible changes and a lot of cell death,” the researcher noted.
The researchers also did a deep dive into previous human clinical data to determine whether Alzheimer’s patients who were taking the anti-seizure drug had slower cognitive decline. They reported that the patients in that category had a “significant delay” in the span from cognitive decline to death compared to those not taking the drug.
“This analysis supports the positive effect of levetiracetam to slow the progression of Alzheimer’s pathology,” the researcher said. (iStock)
“Although the magnitude of change was small (on the scale of a few years), this analysis supports the positive effect of levetiracetam to slow the progression of Alzheimer’s pathology,” Savas said.
Looking ahead, the research team aims to find people who have genetic forms of Alzheimer’s to participate in testing, Savas said.
Limitations and caveats
The study had several limitations, including that it relied on animal models and cultured cells, with no human trials conducted.

Because the study was observational in nature, it can’t prove that the medication caused the prevention of the toxic brain proteins, the researchers acknowledged.
Savas noted that levetiracetam “is not perfect,” cautioning that it breaks down in the body very quickly.

The team is currently working to create a “better version” that would last longer in the body and “better target the mechanism that prevents the production of the plaques.”
“You couldn’t take this when you already have dementia, because the brain has already undergone a number of irreversible changes and a lot of cell death.”
The medication’s common documented side effects include drowsiness, weakness, dizziness, irritability, headache, loss of appetite and nasal congestion.
It has also been linked to potential mood and behavior changes, including anxiety, depression, agitation and aggression, according to the prescribing information. In rare cases, it could lead to severe allergic reactions, skin reactions, blood disorders and suicidal ideation.
