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.

In a medical milestone, a team of US surgeons has deemed an in-utero surgery that adds stem cells to treat spina bifida -- a birth defect -- to be safe. This new type of fetal therapy does not just repair the defect but may also help heal and protect the baby’s developing spinal cord.

The Phase 1 clinical trial, published today in The Lancet and based on six babies, showed that adding a layer of human placenta-derived stem cells to standard fetal surgery can be done safely. The early safety results have prompted the US Food and Drug Administration (FDA), along with an independent monitoring board, to approve the next phase of the study.

Spina bifida, also known as myelomeningocele, occurs when spinal tissue fails to fuse properly during the early stages of pregnancy. The birth defect can lead to a range of lifelong cognitive, mobility, urinary, and bowel disabilities.

While surgeons have previously performed prenatal surgeries, this is the world’s first in-utero stem cell therapy for spina bifida. It is also the only clinical trial aimed at improving outcomes beyond those achieved with fetal surgery alone.

“Putting stem cells into a growing fetus was a total unknown. We are excited to report strong safety results,” said Diana Farmer, the clinical trial’s principal investigator and chair of the Department of Surgery at the University of California-Davis Health.

“It paves the way for new treatment options for children with birth defects. The future is exciting for cell and gene therapy before birth,” she added.

How The Breakthrough Fetal Surgery Was Conducted

Surgeons made a small opening in the mother’s uterus and gently positioned the fetus to expose its back and the spina bifida defect.

A small patch containing living stem cells was then placed directly over the exposed spinal cord before closing the layers of the back to allow the tissue to regenerate.

The stem cells, taken from donated placentas, are designed to protect the developing spinal cord from further damage before birth.

Treating Spina Bifida Before Birth

The findings from the first six babies in the trial, who were closely monitored from surgery through birth, revealed no safety concerns related to the stem cells.

After surgery, the babies experienced no infections or spinal fluid leaks. No abnormal tissue growth or tumors formed at the repair site.

All six surgeries were successful, and the stem cell patch was placed as planned in every case. All surgical wounds healed completely.

MRI scans also showed reversal of hindbrain herniation -- a condition commonly associated with spina bifida -- in all infants, an indicator of surgical success.

Hindbrain herniation in babies, often referred to as Arnold-Chiari II malformation, involves the lower part of the brain descending into the cervical spinal canal.

This can block the flow of cerebrospinal fluid, causing dangerous hydrocephalus (fluid buildup). None of the babies required a shunt for hydrocephalus before hospital discharge, the researchers said.

What Is Spina Bifida

Spina bifida affects about 1 in 2,500 births worldwide, with an estimated 1,500 to 2,000 babies diagnosed each year in the United States alone.

It is a common neural tube defect, with higher prevalence observed in regions with lower folic acid fortification. Open spina bifida specifically occurs in approximately 1 in every 2,875 births.

This surgical intervention aims to significantly improve motor function, and increase the likelihood of walking independently.

The first phase of the trial was funded by a $9 million state grant from the California Institute for Regenerative Medicine (CIRM).

The trial is now enrolling up to 35 patients in its Phase 1/2a study.

Children will be followed through age six to evaluate long-term safety and early signs of improved movement, as well as bladder and bowel function.

Indian drugmaker Dr Reddy's Laboratories is now gearing up to launch its generic semglutide injection in the country in March under the brand name Obeda, reported the news wire agency Reuters. Patent protection for semglutide expires in India in March 2025. This has triggered a rush among Indian drugmakers to come up with lower-cost versions.

Semaglutide is the active ingredient in Danish drugmaker Novo Nordisk's Ozempic and Wegovy, popularly known as the weight loss drugs, but also effective for diabetes and used primarily for that.

Indian Drugmakers Rush For Generic Weight Loss Drugs

Hyderabad-based Dr Reddy's already applied for trademark with the brand name Obeda and a logo, reported Reuters, based on a government filing. In an email response to Reuters, Dr Reddy's spokesperson said, "As semaglutide is yet to be officially launched, it would not be appropriate to refer to or publish any name as the brand name at this stage."

Other companies like Sun Pharma, Zydus Lifesciences, and Nacto Pharma too are entering the rat race of launching multiple generic versions to make the treatment more affordable for patients with obesity and weight-related health risks.

Sun Pharma also announced the plans for "day-one" launches of generic prefilled pens.

Will Launching Generic Weight Loss Drugs Make It Cheaper To Buy?

Until the patent is expired, the semaglutide therapies are owned by the original company. In India, semaglutide injections like Ozempic and Wegovy are soled at a high cost that has limited accessibility to many patients.

Industry analysts, as reported by NDTV, expect that one generic semaglutide enters the market from March 21, 2026, prices could be cut roughly by 50 per cent as compared to the prices it started with. This means Wegovy which was previously sold for around Rs. 10,000 per month could fall somewhere between Rs 3,500 to Rs. 4,000 per month for starter doses.

Dr Reddy's Laboratories have positioned their generic brands competitively, and could potentially offer discounts of up to 50 to 60 per cent in early competition.

How Does Semaglutide Work?

Semaglutide works as a GLP-1 receptor agonist that mimics the GLP-1 hormone to regulate appetite and blood sugar. It slows gastric emptying and makes you feel fuller longer. It also signals the brain to reduce hunger and cravings, and triggers the pancreas to release insulin when blood sugar is high.

They work by increasing insulin release in a glucose-dependent manner, decreasing the liver's production of glucagon, and slowing down the emptying of the stomach, which helps lower blood sugar levels after a meal. They also act on the brain to suppress appetite and increase feelings of fullness, leading to reduced calorie intake.

In people with type 2 diabetes, notes Harvard Health, the body's cells are resistant to the effects of insulin and body does not produce enough insulin, or both. This is when GLP-1 agonists stimulate pancreas to release insulin and suppress the release of another hormone called glucagon.

These drugs also act in the brain to reduce hunger and act on the stomach to delay emptying, so you feel full for a longer time. These effects can lead to weight loss, which can be an important part of managing diabetes.

Scientists for the first time ever developed antibodies that could block Epstein Barr virus or EBV. This is a pathogen that is estimated to infect 95 per cent of the global population. The Epstein Barr virus is also linked with multiple types of cancer, neurodegenerative diseases and other chronic health conditions.

Antibodies for Epstein Barr Virus: How Does It Work?

Scientists used mice with human antibody genes. The team then developed new genetically human monoclonal antibodies that would prevent two key antigens on the surface of the Epstein Barr virus from binding to entering human immune cells.

The findings are published in Cell Reports Medicine. The study shows how the newly identified monoclonal antibodies successfully block infection in mice with human immune systems when they had EBV.

Scientists View On The Antibodies That Block Epstein Barr Virus

"Finding human antibodies that block Epstein Barr virus from infecting our immune cells has been particularly challenging because, unlike other viruses, EBV finds a way to bind to nearly every one of our B cells," explained Andrew McGuire, Ph.D., a biochemist and cellular biologist in the Vaccine and Infectious Disease Division at Fred Hutch. "We decided to use new technologies to try to fill this knowledge gap and we ended up taking a critical step toward blocking one of the world's most common viruses."

What Was the Challenge In The Creation Of Antibodies To Block Epstein Barr Virus?

The key challenge was to pursue human monoclonal antibodies that could actually halt the Epstein Barr virus infection without triggering an anti-drug response to the antibodies themselves. This is a common response among patients who are treated with antibodies raised in other animals.

The researchers targeted two antigens namely: gp350, which helps EBV bind to cell receptors. The second antigen was gp42 that allows EBV to enter and infect human antibody genes. This has led to the monoclonal antibodies to work against gp350 and eight gp42.

"Not only did we identify important antibodies against Epstein Barr virus, but we also validated an innovative a new approach for discovering protective antibodies against other pathogens," noted Crystal Chhan, a pathobiology Ph.D. student in the McGuire Lab. "As an early-career scientist, it was an exciting finding and has helped me appreciate how science often leads to unexpected discoveries."

What Is Epstein Bar Virus (EBV)?

EBV is a highly contagious virus that can pass through bodily fluid contact. It is the cause of one of the most common infections, mononucleosis or mono. Once you get this virus, it stays in your body, inactive and in a dormant state until it becomes reactivated.

According to the Frontiers in Immunology, Chronic active Epstein-Barr virus (CAEBV) disease is a very uncommon problem where people's bodies can't fight off the EBV virus. It keeps getting worse, with a lot of the virus's DNA in their blood and the virus attacking their organs with infected blood cells.

People with this disease often have fevers, swollen glands, a big spleen, liver problems caused by EBV, or low blood counts. Over time, their body's ability to fight off infections gets weaker. If they don't get treatment, they can die from other infections, a problem where the body attacks its own blood cells, organ failure, or cancers linked to EBV.

The only treatment that has been proven to work for this disease is a stem cell transplant (a procedure to replace damaged blood cells with healthy ones). Right now, scientists are trying to figure out why this disease happens. They are looking at problems with the body's defense system (immune defects) and changes in people's genes that might be linked to the disease. A new study as also revealed that EBV may also cause us brain damage due to a disease called encephalitis.

Symptoms Of Epstein-Bar Virus

EBV infections do not cause symptoms especially for children, teens and adults are more likely to experience symptoms like fever, feeling tired or fatigued headache, sore throat, swollen lymph nodes in your neck and arm, enlarged spleen or swollen liver, body aches and skin rash. The symptoms of this usually last for two to four weeks. Things are a bit different with Chronic EBV. In rare cases of EBV, it can lead to a chronic condition called active EBV (CAEVB) some symptoms include, swollen and tender lymph nodes, fever, enlarged liver, fatigue, sore throat, headache, muscle pain joint stiffness, anemia and liver failure.
