‘Vaguely Threatening’: Federal Prosecutor Queries Leading Medical Journal
A federal prosecutor in Washington has contacted The New England Journal of Medicine, considered the world’s most prestigious medical journal, with questions that suggested without evidence that it was biased against certain views and influenced by external pressures.
Dr. Eric Rubin, the editor in chief of N.E.J.M., described the letter as “vaguely threatening” in an interview with The New York Times.
At least three other journals have received similar letters from Edward Martin Jr., a Republican activist serving as interim U.S. attorney in Washington. Mr. Martin has been criticized for using his office to target opponents of the administration.
His letters accused the publications of being “partisans in various scientific debates” and asked a series of accusatory questions about bias and the selection of research articles.
Do they accept submissions from scientists with “competing viewpoints”? What do they do if the authors whose work they published “may have misled their readers”? Are they transparent about influence from “supporters, funders, advertisers and others”?
News of the letter to N.E.J.M. was reported earlier by STAT, a health news outlet.
Mr. Martin also asked about the role of the National Institutes of Health, which funds some of the research the journals publish, and the agency’s role “in the development of submitted articles.”
Amanda Shanor, a First Amendment expert at the University of Pennsylvania, said the information published in reputable medical journals like N.E.J.M. is broadly protected by the Constitution.
In most cases, journals have the same robust rights that apply to newspapers — the strongest the Constitution provides, she added.
“There is no basis to say that anything other than the most stringent First Amendment protections apply to medical journals,” she said. “It appears aimed at creating a type of fear and chill that will have effects on people’s expression — that’s a constitutional concern.”
It’s unclear how many journals have received these letters or the criteria that Mr. Martin used to decide which publications to target. The U.S. attorney’s office in Washington did not respond to a request for comment.
“Our job is to evaluate science and evaluate it in an unbiased fashion,” Dr. Rubin said. “That’s what we do and I think we do it well. The questions seem to suggest that there’s some bias in what we do — that’s where the vaguely threatening part comes in.”
Jeremy Berg, the former editor in chief of the journal Science, said he thought the letters were designed to “intimidate journals to bend over backward” to publish papers that align with the administration’s beliefs — on climate change and vaccines, for example — even if the quality of the research is poor.
Robert F. Kennedy Jr., the nation’s health secretary, singled out N.E.J.M in an interview with the “Dr. Hyman Show” podcast last year as an example of a medical journal that has participated in “lying to the public” and “retracting the real science.”
Andrew Nixon, a spokesman for the Health and Human Services Department, declined to comment on whether Mr. Kennedy had any involvement with the letters.
In the interview, Mr. Kennedy said he would seek to prosecute medical journals under federal anti-corruption laws.
“I’m going to litigate against you under the racketeering laws, under the general tort laws,” he said. “I’m going to find a way to sue you unless you come up with a plan right now to show how you’re going to start publishing real science.”
Dr. Jay Bhattacharya, the new director of N.I.H., has vigorously criticized the leadership of scientific journals. Recently he co-founded a new journal as an alternative to traditional scientific publishing. It has published contrarian views on Covid.
Other prominent journals said they had not received the letter. On Friday, The Lancet, which is based in Britain, published a scathing editorial in solidarity, calling the letters “an obvious ruse to strike fear into journals and impinge on their right to independent editorial oversight.”
“Science and medicine in the U.S.A. are being violently dismembered while the world watches,” the editorial said.
One of Mr. Martin’s letters was sent to the journal Chest, a low-profile publication that publishes highly technical studies on topics like lung cancer and pneumonia. The New York Times reported last week that at least two other publishers had received nearly identically worded letters.
They declined to speak publicly for fear of retribution from the Trump administration.
Dr. Rubin said he, too, was worried about political backlash. Scientific journals rely on public funds in several indirect ways — for example, universities often use federal grants to pay for subscriptions.
“Are we concerned? Of course we are,” he said. “But we want to do the right thing.”
Mr. Martin gave the journals until May 2 to respond to his questions. N.E.J.M. has already responded to Mr. Martin with a statement that pushes back against his characterization of the journal.
“We use rigorous peer review and editorial processes to ensure the objectivity and reliability of the research we publish,” the statement read. “We support the editorial independence of medical journals and their First Amendment rights to free expression.”
This is not the N.E.J.M’s first brush with a Trump administration.
In 2020, the journal published an editorial condemning the president’s response to the pandemic — the first time the journal had supported or condemned a political candidate in its 208-year history.
Dr. Rubin said he doubted Mr. Martin’s letter was related to the editorial. The journal Chest didn’t write about Trump’s first term yet received a letter, he noted.

Are you too old to shovel snow? Experts reveal the hidden heart risks
NEWYou can now listen to Fox News articles!
As snow blanketed parts of the U.S. this week, heart health experts have shared warnings of the physical strain shoveling can take — particularly for older adults.
A 2025 Mayo Clinic review found that just 10 minutes of heavy snow shoveling can push the heart to about 97% of its maximum rate. Exposure to cold air was also found to increase blood pressure and reduce coronary blood flow.
While there isn’t an official age that’s “too old” to shovel, some cardiologists recommend that individuals over 45 should exercise more caution to lower their chances of a cardiac event.
When to take caution
“While there’s no strict age cutoff, generally above the age of mid 40s and above, we tend to be a little more cautious — particularly in people who are less active [without] regular exercise,” Dr. Navjot Kaur Sobti, M.D., an interventional cardiologist at Northwell’s Northern Westchester Hospital in Mount Kisco, New York, told Fox News Digital.

“Certainly in people who are above the age of 65 — and who have risk factors for heart disease, such as high blood pressure, high cholesterol, diabetes, obesity or sedentary lifestyle — we recommend being very, very cautious about shoveling snow,” she advised.
Dr. John Osborne, M.D., a practicing Texas cardiologist and volunteer for the American Heart Association, shared similar guidance for people older than 45, especially males over 65.
SIMPLE NIGHTLY HABIT LINKED TO HEALTHIER BLOOD PRESSURE, STUDY SUGGESTS
“Unless you are in good cardiovascular shape and conditioned, it may be a good idea to ask someone for help,” he said in an interview with Fox News Digital.
The impact of snow removal is especially concerning for those with existing cardiovascular risks and a history of heart attack or stroke, according to the cardiologist. “People with these characteristics and those who have had bypass surgery or coronary angioplasty simply should not be shoveling snow in any conditions,” he said.

Osbourne said he often sees cardiac episodes in people who are typically sedentary and sit at a computer most of the day with little or no exercise. “Then once or twice a year, they go out and try to shovel the driveway after a heavy snowfall, and that unexpected exertion can unfortunately lead to tragedy.”
Hidden strain
The stress that is placed on one’s heart while shoveling snow is similar to what occurs during a cardiac stress test, Sobti pointed out, and may even exceed it.
Cold temperatures can cause blood vessels to constrict and blood pressure to spike — which, coupled with existing hypertension and the exertion of lifting snow, can significantly tax the heart, she warned.
“It’s almost like an at-risk person is putting themselves through an unsupervised maximal exertion stress test without a cardiologist actively monitoring them,” Sobti told Fox News Digital.

In addition to the exertion of shoveling, frigid temperatures can also strain the heart. Recent research has shown that cold exposure accounts for nearly twice as many cardiovascular deaths as heat exposure, including heat exhaustion.

That study, published in the Annals of Internal Medicine last month, also found that those over age 65 had higher rates of temperature-related deaths.
“So the risk is very, very high,” Sobti cautioned. “It’s really that sudden rise in blood pressure coupled with the physical stress of snow shoveling itself.”
Safer shoveling tips
The cardiologist said it’s ideal to have someone else help with snow removal — but if you do choose to use a shovel, she recommends pacing yourself and using a “pushing or sweeping” motion instead of heavy lifting.

To protect against the cold, Sobti also recommends covering your mouth, nose and extremities, wearing a hat and gloves, and using extra caution in windy conditions.
Using an automated snow blower can still raise the heart rate — up to 120 beats per minute, compared to 170 while shoveling, the American Heart Association states on its website.

It is also important to be aware of any symptoms of a potential cardiac issue while shoveling, Sobti emphasized.
If a person starts to experience warning signs such as chest pain, shortness of breath, a racing heart or palpitations, those should not be ignored.

Even if the symptoms resolve after a few minutes, a person “could still be experiencing symptoms of a heart attack” and should call 911 for evaluation, Sobti said.
“It’s better really to be safe than sorry.”

Nutrient deficiency linked to heart disease risk for millions, new study warns
NEWYou can now listen to Fox News articles!
More than three-quarters of the global population is falling short on omega-3 intake, a nutrient gap that may increase the risk of heart disease, cognitive decline, inflammation and vision problems.
That’s according to an analysis published in Nutrition Research Reviews, in which researchers from the University of East Anglia, the University of Southampton and Holland & Barrett analyzed omega-3 intake patterns across multiple countries and age groups.
The review found that 76% of people worldwide are not meeting the recommended levels of two omega-3 fats that are essential for heart health: eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA).
TREATING GUM DISEASE COULD REDUCE RISK OF HEART ATTACKS AND STROKES, STUDY SUGGESTS
The analysis considered recommendations from global health authorities and assessed how closely populations follow them.
Most adults should aim for at least 250 milligrams of EPA and DHA per day, though actual intake is far lower in many regions, according to the researchers.

To explore the health implications of low omega-3 intake, Fox News Digital spoke with Michelle Routhenstein, a New York–based preventive cardiology dietitian at Entirely Nourished.
HIGH-POTASSIUM FOODS COULD ‘SIGNIFICANTLY’ LOWER RISK OF HEART FAILURE, STUDY FINDS
Low omega-3 levels can have a noticeable impact on heart health, cognitive function and inflammation throughout the body, the expert confirmed.
Low intake can also increase the risk of heart attacks and sudden cardiac death, she added. It’s also associated with higher triglycerides, irregular heart rhythms and plaque in the arteries.

Inadequate omega-3 levels have also been linked to changes in brain function, including faster cognitive decline, a higher risk of Alzheimer’s disease and increased rates of depression.
Routhenstein noted that low levels may also worsen inflammation in autoimmune conditions such as psoriasis, and can negatively affect eye health, since omega-3s play a key structural role in the retina.
SITTING ALL DAY? NEW STUDY SAYS CERTAIN FOODS MAY PROTECT YOUR HEART FROM DAMAGE
To improve omega-3 levels, the expert said it’s important to understand how much is needed and where to get it.
“The richest dietary sources of EPA and DHA are oily fish, such as salmon, mackerel, sardines, herring, trout and anchovies,” Routhenstein told Fox News Digital.

Many people benefit from eating oily fish more frequently, often three to four times per week, Routhenstein noted. For individuals who do not eat fish regularly, supplements can help raise EPA and DHA to healthier levels.

For those taking omega-3 supplements, dosing should be based on lab results, medications, omega-3 levels and overall medical history, according to Routhenstein. Moderate, quality-controlled supplements are generally considered safe for most people.

There is also some evidence supporting prescription-strength omega-3 products.
“High-dose EPA, such as 4 grams per day of icosapent ethyl, has been shown to reduce major cardiovascular events in certain high-risk populations, while similar doses of mixed EPA/DHA have not consistently shown the same benefit,” Routhenstein said.
Omega-3 dosing should be individualized based on lab data, medication use, current levels and overall medical history. (iStock)
Testing omega-3 levels can also help determine whether intake is adequate. The omega-3 index, a blood test that measures EPA and DHA in red blood cells, is considered one of the most reliable ways to assess status.

“Levels around 8% are associated with lower cardiovascular risk, while levels below approximately 4% are considered low,” Routhenstein said.
Understanding baseline levels can help guide more personalized decisions about diet and supplementation.

5 winter-weather essentials to protect skin health in dangerously cold temperatures
NEWYou can now listen to Fox News articles!
As winter weather moves in, cozy essentials like scarves, plush throws and heated bedding become everyday comforts.
But dermatologists caution that these cold-weather favorites can secretly undermine skin health — trapping sweat and bacteria, causing irritation and exposing the skin to excess heat.
Choosing the right materials for wellness — and using them safely — can make a big difference.
VIRAL ALL-WHITE WELLNESS PUSH COULD BOOST MENTAL HEALTH — HERE ARE 4 ESSENTIALS TO CONSIDER
Here are five winter must-haves and gift ideas, with expert tips on how to keep skin healthy and happy while staying warm this season.
