Singer Jesy Nelson recently shared an emotional update regarding the complications she is experiencing in her pregnancy with twin babies. Former Little Mix singer Jesy, who is having twins with partner Zion Foster, announced that she has been diagnosed with pre-twin-to-twin transfusion syndrome (pre-TTTS). The condition, which is present in pregnancies involving twins with a shared placenta, has serious risks involved and needs intense medical supervision. As Nelson embarks on this difficult journey, her story enlightens us about a rare but dangerous condition many expectant parents may not know much about.

Twin-to-twin transfusion syndrome is a rare but dangerous condition that arises in monochorionic twin pregnancies, in which identical twins share a single placenta. The placenta supplies the developing babies with oxygen, nutrients, and blood flow, but in TTTS, there is an imbalance of blood vessels that interconnect the twins, and thus the vital resources are not evenly distributed. One twin, or the donor twin, shares excess blood with the other, referred to as the recipient twin. This leads to one baby becoming malnourished and possibly anemic, and the other in danger of heart problems due to too much blood.

Nelson described her diagnosis in a heartfelt Instagram video, explaining that she is currently in the pre-stage of TTTS and undergoing frequent monitoring. "I am being scanned twice a week, and each time, things have gotten a little worse," she shared, expressing her fears and hopes for the health of her babies.

Potential Risks of TTTS

If left untreated, TTTS can have devastating consequences. Medical research indicates that:

• 90% of the cases of untreated TTTS lead to loss of one or both twins.
• Despite treatment, only a 70% survival rate for both twins is assured.
• Severe forms can result in preterm labor, cardiac failure in the recipient twin, and organ failure in the donor twin.
• Complications in long-term survivors include neurological damage and developmental delay in surviving infants.

TTTS usually advances in stages, beginning with minimal changes in fluid levels and worsening as one twin continues to get an unequal share of blood. In extreme cases, fetal laser surgery, referred to as the Solomon technique, can be employed to divide the blood vessels and balance the twins.

Why Identical Twin Pregnancies Are More Complicated

Identical twins may develop differently, and their own unique form of placental sharing can have a dramatic effect on pregnancy risk. Jesy Nelson's twins are considered monochorionic diamniotic (mono/di), which means they share a placenta but have two amniotic sacs. This is the type of pregnancy in about 70% of identical twin pregnancies and carries an increased risk of complications like TTTS, umbilical cord entanglement, and growth restriction.

Conversely, dichorionic diamniotic (di/di) twins both have a separate placenta and amniotic sac, which greatly diminishes the threat of TTTS. Twin pregnancy type is normally identified by early ultrasound, with physicians being able to track future complications from inception.

Other Twin Pregnancy Health Risks

Twin pregnancies, even without the presence of TTTS, entail a variety of health risks to the mother as well as infants:

1. Premature Birth

Over 60% of twin pregnancies end in premature delivery, with birth usually taking place before 37 weeks. Premature infants can have immature organs and need neonatal intensive care (NICU) assistance to assist with breathing, feeding, and infection fighting.

2. Gestational Hypertension and Preeclampsia

Pregnant women with multiples are at increased risk of having high blood pressure during pregnancy. This, if left untreated, can result in preeclampsia, a serious complication of pregnancy that can result in damage to organs, preterm labor, and in some cases, maternal or fetal death.

3. Anemia

Pregnant women carrying multiples are twice as likely to experience anemia, a condition where the body does not produce enough healthy red blood cells. This can lead to fatigue, dizziness, and complications during delivery.

4. Birth Defects

According to John Hopkins Medicine, multiple birth babies are twice as likely to have congenital abnormalities compared to single births. These can include heart defects, neural tube defects, and gastrointestinal issues.

5. Amniotic Fluid Imbalances

When twins have to share a placenta, they are more likely to have polyhydramnios (excess amniotic fluid) or oligohydramnios (not enough amniotic fluid). Both result in distress to the babies during fetal development and can result in premature labor.

6. Postpartum Hemorrhage

Twins are at increased risk of excessive postpartum hemorrhage because their uterus is larger and there are greater blood supply needs.

Jesy Nelson's openness about her challenging experience is raising awareness for TTTS, a condition that few individuals—let alone expectant mothers and fathers—might be aware of. Through her tearful video, Nelson stressed the significance of knowing about twin pregnancies aside from the thrill of having multiples. "We had no idea that this type of thing occurs when you're having twins. We just desperately want to make people aware of this because there are so many people who aren't aware."

Her case reminds us of the intricacies involved in twin pregnancy and the significance of early identification and medical management. For mothers carrying twins, frequent ultrasounds and vigilance can become a life-and-death issue for early detection and better outcomes of both babies.

Through constant medical attention and care, she and her partner Zion Foster remain positive and get ready for their babies to be born. In other parents whose situations are no different, the story of Nelson highlights awareness, medical progress, and emotional encouragement in handling complicated pregnancies.

The expecting parents of twin siblings are advised to discuss TTTS screening and possible interventions with their physicians to give their babies the best chance.

It is no news that all appointments in the United States' Health Departments that have been made under RFK Jr are of the people who have been vaccine critiques. In a similar scenario, Dr Ralph Abraham, a state surgeon from Louisiana, who had ordered health officials to stop promoting mass vaccination will now serve as the US Centers for Disease Control and Prevention's (CDC) principal deputy director.

It was in February when Abraham instructed health department staff to stop promoting vaccines for preventable diseases.

He wrote in a February 13 internal memo that although patients should continue speaking with their providers about the risks and benefits of vaccination, the health department will stop promoting mass vaccination. The memo was issued on the same day Robert F. Kennedy Jr. was sworn in as secretary of the US Department of Health and Human Services. While his hiring has not been announced by HHS, but his new role has been confirmed. It was first reported by health newsletter Inside Medicine.

Who Are Part Of The CDC?

As of now the CDC does not have a permanent director. Kennedy ousted Dr Susan Monarez from the role in August. Jim O'Neill, who is serving as the deputy HHS secretary said this month that the agency has had "mission creep" and needs to focus on its original mandate.

“We want to … take the people we have and put them to their best use. And secondly, we are always recruiting. We are eager to hire wonderful scientists and data engineers and AI engineers and researchers and drug reviewers across the department, including CDC. If you are talented, you care about health or human services – please come work with us.”

What More Do We Know About Ralph Abraham?

The news of his appointment comes days after the CDC changed its guidelines on vaccines on its website. The CDC website now links vaccines with autism and states that "vaccines do not cause autism is not an evidence-based claim".

While Abraham has not outrightly been anti-vaccine, he had asked the health staff to not promote it for preventable diseases or infection and has long echoed Kennedy's 'Make America Healthy Again' (MAHA) rhetoric. He had questioned trust in the pharmaceutical industry and public health institutions.

“The solution to increased spending and declining outcomes in our country is unlikely to come in the form of a pill or a shot,” Abraham said in a February statement. “Much of the solution will likely come down to the usual hard work of improving diet, increasing exercise, and making better lifestyle choices.”

Changes In CDC

Apart from the guidelines being changes on autism and vaccine link, in August, Kennedy dismissed all members of the CDC's Advisory Committee on Immunization Practices (ACIP), the body whose recommendations form the basis of state immunization mandates.

Just days later, eight new members were named—though one withdrew amid ethics concerns. Unlike their predecessors, this panel includes only one epidemiologist and one infectious disease specialist, with no virologists or immunologists. Many appointees lack peer-reviewed vaccine research altogether, and those who do have published, on average, 78% fewer vaccine-related papers than former members.

The long-standing practice of adding fluoride to community drinking water in the United States is now under sharp review as questions rise about whether its advantages continue to outweigh possible risks. A fresh set of findings pushes back against recent warnings about fluoride in water and suggests that it might offer added benefits.

This renewed national discussion began after a government report from the National Toxicology Program stated that high fluoride exposure was tied to lower IQ in children. That report, however, assessed fluoride amounts that were at least twice higher than federal recommendations and had limited information about what happens at lower, commonly used levels, as per CNN.

However, the latest study examined fluoride quantities that match the usual suggested range in drinking water. Researchers found strong evidence showing that children who grew up with water containing these lower levels of fluoride performed better on cognitive assessments than those who had no fluoride exposure.

Fluoride in US Public Water Faces Renewed Questions

Dr. Rob Warren, lead author of the study released in Science Advances, said he was surprised by the National Toxicology Program’s earlier conclusions and felt the need to produce evidence more suitable for public policy. He explained that he pursued the work because it was a major question without a clear answer.

The national debate has also intensified as US Department of Health and Human Services Secretary Robert F. Kennedy Jr. has labeled fluoride an industrial waste and pointed to possible IQ loss while calling for a rollback of federal guidance. Utah and Florida have already moved to prohibit fluoridation of public water.

As per CNN, Warren compared the situation to testing a heart medication. If the advised dose is 100 milligrams, but a study measures reactions to nearly a million milligrams, the results do not reflect what happens at the normal dose. He said that this is how much of the fluoride research has been structured and that only extremely high doses have shown harmful effects, which is not helpful for policy decisions.

Warren directs a long-running program that began in the US Department of Education and has followed tens of thousands of Americans from their high school years in the 1980s through several decades.

Fluoride and Cognition: What The Study Found

For the current analysis, the team linked math, reading and vocabulary test scores from nearly 27,000 participants to the level of fluoride in their childhood drinking water. These measurements were based on older records from the US Geological Survey and the Department of Health and Human Services, as per CNN.

Researchers worked under the assumption that participants spent their entire upbringing near their high schools. They sorted people into three groups. One group had steady exposure to recommended fluoride levels either through natural sources or public water treatment. Another group never had fluoride in their water. A third group had mixed exposure because their community changed its water policy at some point.

Students who had fluoride for only part of their childhood scored higher on tests than peers who never had it. Those who grew up with fluoride throughout all their childhood years scored even better. Follow-up testing that continued up to 2021, when many had reached about 60 years of age, also showed no sign that fluoride contributed to cognitive decline.

Warren clarified that cognitive tests are not exact IQ scores, although they relate strongly. Test results reflect both mental ability and the learning opportunities a person receives. He is currently working on a follow-up project that will look more closely at fluoride and IQ with improved childhood location data.

Other studies this year suggested that removing fluoride from public water in the United States could lead to more than 25 million extra cavities among children and teenagers in five years along with nearly 10 billion dollars in dental treatment costs. Although the new study did not measure dental health, experts noted that pain from untreated cavities can interfere with a child’s ability to attend school or stay focused, which may influence academic scores.

Why Experts Still Differ on Fluoride Policy

Fluoride occurs naturally in some groundwater and foods. It protects teeth by strengthening enamel, which can be damaged by acids formed from bacteria, plaque and sugar. Communities in the United States started adding fluoride to water systems in 1945 to improve oral health in a cost-effective way.

The American Dental Association and numerous specialists continue to support community water fluoridation. The US Centers for Disease Control and Prevention has also kept its recommendations unchanged. The agency does not have authority to require fluoridation, but it considers 0.7 milligrams per liter the ideal amount.

Recently, the US Food and Drug Administration restricted the use of prescription fluoride supplements. The agency noted that unapproved fluoride products may alter the gut microbiome and that better options exist to protect teeth.

In a written response published with the new research, Dr. David Savitz from Brown University argued that before ending a decades-long public health practice, there must be clear proof of harm at commonly used fluoride levels. He wrote that there is still no convincing evidence that fluoridation lacks benefit or causes damage at recommended doses.

He quoted a well-known saying, noting that if something is not broken, there is no reason to fix it. He said the new study suggests that fluoridated water remains on the side of being effective and safe.

The Neuralink chip is a piece of technology that’s hoped will one day allow people to operate devices like phones and computers using their thoughts. Its creator, tech mogul Elon Musk, describes it as a “Fitbit in your skull with tiny wires.” Elon Musk's brain implant company Neuralink said recently that 12 people worldwide have received its chips. The device is meant to have several applications, from restoring motor functionality within people to enabling a brain-computer interface. The question now is whether it will be able to reverse paralysis in the future or not.

Neuralink: What Is Neuralink, And What Does It Do?

Neuralink is a neurotechnology company Musk set up in 2016. The device is roughly the size of a coin and is implanted into the skull, with hair-thin threads placed inside specific parts of the brain to form a working brain-computer interface.

The implant records brain signals and transfers them to an external device, such as a smartphone, through Bluetooth. Its first product, Telepathy, is designed to let a person operate their phone or computer through intention alone. By placing the chip in regions that manage movement, Neuralink believes it could help people living with neurological conditions. Musk has said that early users would likely be people who cannot use their limbs.

Neuralink: What Testing Has Neuralink Carried Out In The Past?

As per Reuters, the company has run trials using monkeys and pigs. Demonstrations have featured monkeys moving a cursor or playing simple on-screen games using the implant. Neuralink maintains that no monkey died because of the device itself, though reports have circulated describing complications in some animals, including paralysis, seizures and swelling in the brain.

Neuralink: Can Neuralink Cure Paralysis?

The human brain contains millions of neurons responsible for movement, emotion and thought. These neurons send electrical signals down pathways that run from the brain to the rest of the body. If a person tries to stand up, the brain sends electrical instructions to the legs, and the reaction is instant. Paralysis develops when pathways in the spinal cord are damaged or blocked, according to the description on Neuralink’s website.

Because the Neuralink implant reads the brain’s signals, it can forward those signals to the limbs even when the spinal cord no longer relays them. This would require one implant in the brain and another placed below the injured area of the spinal cord. With steady training, a person could regain movement, raising the possibility that Neuralink may one day help restore mobility.

Neuralink Ethical Concerns

Experts have questioned the company’s experiments on animals and the general risks linked to brain operations, which can include seizures or bleeding. They have also pointed to worries about data privacy and long-term surveillance, since there is limited detail on how much control users will have over their neural information.

Earlier this year, the US Department of Transportation fined the company for failing to register as a carrier of hazardous biological material, including implants removed from primates, according to agency records reviewed by Reuters.

Neuralink Is FDA Approved

In late May 2023, the FDA granted Neuralink permission to start human testing. The company said on Twitter that the approval marked the beginning of its first clinical study in people, calling it a vital step toward making the technology accessible in the future.

Neuralink has continued to share updates, and in July 2025, it announced that it had completed two brain-implant procedures on the same day. Both individuals are said to be recovering well. Musk responded soon after, expressing confidence in what the technology might achieve in the coming years.
