MRI scans are strong diagnostics with high-definition images of what lies inside a body. Strong magnetic fields require precaution, as brought out by an instance where a young woman suffered very serious injuries due to an oversight in a metallic core within a silicone sex toy that she happened to have before the MRI scan. This makes a stark reminder about the potentially deadly consequences of missing metal objects when such procedures are being performed. In April 2023, a 23-year-old woman went into an MRI with a silicone plug containing a metal core that was not known.

She thought that the item is made entirely out of silicone according to the advertising. However, the strong magnetic field of the MRI machine interacted with the hidden metal, dragging the object through her body and causing excruciating pain. According to reports from the U.S. Food and Drug Administration (FDA), the scene was harrowing, with the woman screaming in agony and requiring immediate hospitalization. Despite pre-scan screenings, which are routine prior to a scan, the patient did not inform the facility that the object existed because he presumed it was purely non-metallic. This caused serious injuries that led to the patient's law suit against the manufacturer for deceitful misrepresentations of material content.

MRI machines employ magnets between 0.5 to 3 Tesla (T). This is thousands of times stronger than the Earth's magnetic field. The tremendous force causes ferromagnetic materials, like iron and nickel, to be magnetized quickly and become strongly attracted toward the magnet. Objects as small as hairpins or paper clips will accelerate at 40 miles per hour inside the magnetic field.

The force can lead to catastrophic injuries in items lodged within the body, such as metallic implants or foreign objects. Metallic cores within devices, like pacemakers or intrauterine devices, must be disclosed to radiologists to prevent such complications.

How Metal Objects Interact with MRI Fields?

On these claims, Dr. Adam Taylor, a specialist in human anatomy, weighed his words in a international health website and added that the distance away and mass of this object would increase its velocity towards that of sound, "The acceleration would be phenomenal, but with a metallic core, it can't go anywhere near supersonic speeds. As for the size, the magnetic acceleration to the internal soft tissues would ensure that there could be severe intracranial trauma."

The injuries inflicted in this case likely involved damage to major blood vessels, nerves, or organs, highlighting the devastating impact of even minor oversight during an MRI scan.

This is not an isolated case. There are documented cases of metallic objects causing serious damage during MRI scans with a 65-year-old man with schizophrenia swallowed metal objects, including sockets and a hinge pin. The powerful magnetic field during an MRI scan caused the objects to rupture his stomach, resulting in serious injuries.

A toddler who ingested 11 small magnets perforated his bowel while undergoing a scan, making his case unique. In another deadly but extremely rare incident, there have been people who hide a firearm on themselves during MRI procedures. Magnetic attraction can trigger a discharge in a weapon and has led to some fatal injuries.

These cases emphasize the very strong need for adequate screening and patient education prior to an MRI.

Preventing MRI-Related Incidents

Medical professionals have been trained to avoid risks. This is by properly screening a patient for metallic objects. In general, most pre-scan protocols include:

• Patients are interrogated about implants, recent surgery or exposures at work related to metals.
• Radiologists sometimes use handheld metal detectors to search for hidden items.
• People who work with metal, like welders or machinists, will need additional testing to detect microscopic metal fragments within soft tissues or eyes.

The case emphasizes the importance of product labeling by manufacturers, especially those products that are likely to unintentionally cause harm to health. The patient's assumption that her device was 100% silicone points to a larger problem in consumer markets with misinformation.

It also reminds the patients to report any possible dangers to the medical professionals, no matter how the objects look non-metallic. In sensitive cases, patients can request private discussions with healthcare providers to ensure safety without discomfort.

In the end, it is a joint effort from manufacturers, healthcare professionals, and patients that can prevent such tragedies. Manufacturers must ensure truthful marketing, while healthcare providers should educate patients about the dangers of metal objects in MRI settings. For patients, understanding the risks and actively participating in pre-scan disclosures can be lifesaving.

This young woman's experience is a sobering example of the unforeseen dangers posed by MRI machines when precautions are overlooked. It serves as a wake-up call to address gaps in patient awareness, medical protocols, and product transparency. By learning from this incident, the medical community and the public can work together to ensure MRI scans remain a safe and effective diagnostic tool.

Chronic hepatitis B infections among children and young adults in the United States could rise by 83% if the country moves away from routinely recommending vaccination at birth for all newborns, according to a new study titled Projected Effect of 2026 Federal Changes to the Childhood Immunization Schedule on Chronic Hepatitis B Virus Infections in the United States, published in Annals of Internal Medicine recently.

Researchers from Massachusetts General Hospital and Harvard Medical School analysed outcomes for a birth cohort of 3.6 million infants over their first 20 years.

The study examined the impact of changes to US hepatitis B vaccine recommendations for babies born to mothers who test negative for the virus.

Under the revised approach, parents and healthcare providers decide together whether and when to begin vaccination. The findings suggest that this could leave more children vulnerable to infection, increasing the cases of chronic hepatitis B.

What Did The Study Find?

The model compared universal vaccination at birth with two alternatives. The first is delaying the first dose until at least two months of age, and the second is leaving the decision to parents and healthcare providers.

Researchers estimated that delaying vaccination could increase chronic hepatitis B infections acquired by age 20 by 19%. Under the second option, the estimated increase was 83%.

The model estimated 255 chronic infections under universal birth-dose vaccination, compared to 303 if vaccination was delayed and 467 under shared decision-making.

The number of people who remained at high risk to hepatitis B at age 20 was also projected to increase. Under universal vaccination at birth, around 232,000 people in the cohort would remain at risk. This rose to 474,000 with delayed vaccination and approximately 1.8 million under shared decision-making.

Study's corresponding author Amir Mohareb said, “These findings show why policy makers should re-implement recommendations for universal hepatitis B vaccination at birth.”

Importance Of Hepatitis B Birth Dose

Hepatitis B is a viral infection that affects the liver and spreads through infected blood and certain bodily fluids, including during childbirth. Infection acquired during infancy is likely to become chronic, leading to cirrhosis, liver failure or liver cancer in the future.

The universal hepatitis B birth-dose recommendation was introduced in the US in 1991. The first dose provides early protection, including when maternal infection is missed or a child's exposure risk is not recognised.

In December 2025, the US Advisory Committee on Immunization Practices recommended replacing universal vaccination at birth with shared decision-making for infants whose mothers test negative.

The Centers for Disease Control and Prevention adopted this approach in January 2026. Babies born to mothers who test positive or whose infection status is unknown continue to be recommended to receive the birth dose promptly, along with hepatitis B immune globulin when indicated.

Increase In Infections, Deaths And Costs

The changes in vaccine policy is also likely to lead to hundreds more infections, deaths, and millions of dollars in higher costs, according to another research published in JAMA Pediatrics.

Pediatricians, public health experts, and dozens of medical groups warned that it could harm children and their families. So the JAMA studies modelled the potential impact of the policy.

The first study estimated that delaying the first hepatitis B vaccine dose by two months for babies born in a single year to mothers who tested negative — about 80 percent of the 3.6 million US births annually — would increase lifetime health-care costs by at least $16 million, The Washington Post reported. If vaccination were delayed by seven months, it would cost an additional $19.8 million.

The second study modeled what would happen if only 10 per cent of babies born to unscreened mothers received a birth dose; an additional 628 babies would get infected.

“One of the most concerning implications is how many more infected Hep B babies will we see,” said co-author Rachel Epstein, a pediatric and adult infectious diseases clinician at Boston Medical Center.

“A universal birth dose helps prevent a substantial number of infections in babies of a lifelong condition that we do not have a cure for,” she added.

Scientists have identified a new H1N1 mutation, G155E, in US flu samples, raising questions about immunity and vaccine protection as the flu season begins early.

Early laboratory findings suggest the mutation may make some H1N1 strains harder for existing antibodies to recognize. However, the vaccine’s effectiveness specifically against G155E remains uncertain, and there is no evidence yet that the mutation makes the flu shot ineffective.

H1N1 Becomes The Dominant Flu Strain In US

According to the US Centers for Disease Control and Prevention’s (CDC) October 2 report, 53 of 55 influenza A samples undergoing subtyping were H1N1, while two were H3N2. No influenza B viruses were reported in this group.

Researchers at the University of Washington identified G155E in 13 of 17 sequenced H1N1 samples collected from hospitals and clinics in the Seattle area.

The 2026-2027 flu vaccines approved by the US Food and Drug Administration target H1N1, H3N2 and an influenza B virus.

Dr. Jennifer Duchon, a pediatric infectious disease expert at Mount Sinai Children’s Hospital, told Reuters that younger people may have had limited exposure to this year’s H1N1 strain.

“What people are a bit worried about is that the H1N1 strain this year hasn't been seen by a lot of younger folk, so it may be more severe in them,” she said.

However, this concern does not establish that G155E causes more severe disease. Flu vaccine effectiveness varies by season and depends partly on how well vaccine strains match circulating viruses.

Scott Hensley, a microbiologist at the University of Pennsylvania, told Reuters that two of this season’s three vaccine components appear well matched to circulating strains. He also recommended getting vaccinated early.

The American Medical Association also recommends annual flu vaccination for people aged six months and older, unless they have a medical reason not to receive it.

Antibody studies suggest that people exposed to influenza last year may have antibodies that recognize the new mutation less effectively, particularly among teenagers and young adults.

Researchers at the Fred Hutchinson Cancer Center, including virologist Jesse Bloom, examined antibody responses to influenza A strains carrying mutations such as G155E.

In a preprint posted on bioRxiv, researchers tested antibodies from 260 people in Australia and the US against 148 influenza A strains that circulated through mid-2026. Some G155E-carrying strains were less readily recognized by antibodies, particularly those from younger people.

The researchers suggested that limited previous exposure to similar H1N1 variants could help explain this difference. However, laboratory findings alone cannot establish how likely people are to become infected or develop severe illness.

Should You Worry About G155E?

The mutation warrants monitoring, but current evidence does not establish that it makes the flu shot ineffective. How well this season’s vaccine protects against G155E remains uncertain.

Annual flu vaccination remains an important preventive measure, particularly for people at higher risk of complications. Regular hand hygiene and other basic precautions can also help reduce the spread of infections.

Emmy-winning American actor Christina Applegate has in a shocking news revealed that she does not have multiple sclerosis (MS), despite continuing to experience debilitating symptoms since her 2021 diagnosis.

Applegate, 54, shared the news in an episode of her podcast MeSsy, co-hosted with fellow actor Jamie-Lynn Sigler and posted to YouTube on Tuesday.

“I’m back at square one – that I don’t know what’s going on with me,” she said through tears.

Applegate had gradually withdrawn from public life after her MS diagnosis in 2021, as she navigated the physical and emotional toll of the condition.

She has also become an advocate for MS awareness and chronicled her struggles in an emotional memoir published in March.

Applegate recalled a visit to her doctor when she was told she did not have MS.

“She came into my room and said, ‘Congratulations, you don’t have MS,’” Applegate recalled through tears. “I was, like, not happy at all. Everybody else was so happy.”

Despite the news, Applegate said her symptoms have not improved.

“I haven’t gotten better. I still have to use wheelchairs when I go to the doctor’s office. I can’t walk from the car to the room. I’m still in this. Nothing magical happened when she said, ‘You don’t have MS.’ Nothing magical happened.”

Applegate also described feeling confused about her condition and the uncertainty surrounding her symptoms.

“It’s weird because I feel like I let everybody down. It’s this weird feeling of like I became this, you and I, the poster children for MS. Everything that I was doing, I had a fucking reason as to why my day sucked every day.

“And now I don’t have a reason. It’s very unnerving and it’s really confusing for me.”

According to the National Institute of Neurological Disorders and Stroke, multiple sclerosis is a chronic neurological condition that affects the central nervous system, including the brain, spinal cord and optic nerves.

MS is also an immune-mediated disease in which the immune system attacks myelin, the protective sheath surrounding nerve fibers. Damage to myelin can disrupt nerve signals, causing symptoms that vary from person to person.

These may include muscle weakness, fatigue, numbness, coordination problems, vision changes and memory difficulties.

MS is commonly diagnosed between the ages of 20 and 40, although it can develop earlier or later. There is no cure, but treatments can help manage symptoms and slow disease progression. Some people experience relapses with periods of improvement, while others develop progressively worsening disability.

Why Is Multiple Sclerosis Hard To Diagnose?

Dr. Marwa Kaisey, an associate professor in the Department of Neurology at Cedars-Sinai Medical Center, joined Applegate and Sigler on the podcast to discuss MS misdiagnosis.

Kaisey said misdiagnoses are “fairly common” because there is no single test that can definitively confirm or rule out MS.

“We don’t have one single test for MS. It’s not like we have something like a pregnancy test that says, ‘Yes. You have it.’ ‘No. You don’t.’ It’s a list of criteria.”

Kaisey said nearly 20% of people diagnosed with MS may not actually have the disease, People.com reported.

“Almost one in five of these people who’d been told they had MS, some for decades, didn’t actually have it. And a majority of them were on medication to treat their MS,” she said.

MS diagnosis typically involves assessing symptoms, a neurological examination, magnetic resonance imaging (MRI) and, when appropriate, additional tests to rule out other conditions.

Because several disorders can cause similar symptoms, clinicians must evaluate the findings against established diagnostic criteria.
