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.

For years, people with type 2 diabetes who needed insulin had to administer an injection daily. Eli Lilly’s newly approved insulin is set to bring a dramatic reduction in that burden from roughly 365 injections a year to just 52.

The US Food and Drug Administration (FDA) has approved Onswik (insulin efsitora alfa-gobe), a once-weekly basal insulin for adults with type 2 diabetes. It is designed to provide a steady level of insulin over seven days and is used alongside diet and exercise to control blood sugar. Find out how different weekly insulin is from the daily shots that patients are used to?

Lilly's Once-Weekly Insulin Gets FDA Approval

Insulin is a hormone that helps glucose move from the bloodstream into cells, where it can be used for energy. It also helps reduce the amount of glucose produced by the liver. People with type 2 diabetes may eventually need insulin when their bodies do not produce enough of it or cannot use it effectively.

Basal insulin is long-acting insulin designed to work in the background throughout the day and night, helping keep blood sugar levels under control between meals and overnight.

Until now, commonly used basal insulins like insulin glargine and insulin degludec have generally required daily injections.

Onswik is a long-acting insulin analogue designed to remain active for an entire week. Instead of injecting a smaller amount every day, patients receive one subcutaneous injection on the same day each week. That could reduce the number of basal insulin injections by more than 300 a year compared with daily treatment.

For someone who finds daily injections difficult to maintain, that development could be gamechanging.

Comparison Between Weekly Insulin & Daily Insulin

Lilly's late-stage QWINT programme included more than 3,400 adults with type 2 diabetes across four Phase 3 studies. Onswik met its primary goal in each study, reducing HbA1c, a measure of average blood sugar over time, by an amount that was not inferior to daily basal insulin.

The studies included people who had never previously used insulin as well as people already receiving insulin treatment.

So the significance of the approval is not that weekly insulin necessarily works better than daily insulin. Rather, it offers comparable blood-sugar control with far fewer injections.

Taking insulin every day can become another task in an already demanding diabetes care routine. Missed or delayed doses can make blood sugar management more difficult. A weekly option could simplify treatment for some patients and potentially make it easier to stay consistent. But convenience does not mean the treatment becomes risk-free.

What Are The Risks & Who Can Take It?

The most important risk remains hypoglycaemia, or dangerously low blood sugar, which is a known risk with insulin.

Severe hypoglycaemia can cause confusion, seizures, loss of consciousness and, in serious cases, death.

Other reported adverse effects of Onswik include allergic reactions, injection-site reactions, changes in fat tissue at injection sites, itching, rash, swelling and weight gain.

The FDA also warns about medication errors and accidental overdose, low potassium levels and fluid retention or heart failure when the medicine is used with certain other drugs.

The FDA approval is specifically for adults with type 2 diabetes. Onswik is not recommended for people with type 1 diabetes due to the risk of severe hypoglycaemia. It is also not a replacement for other aspects of diabetes management.

A new study has identified 485 chemicals used in pesticide products in the US that are linked to breast cancer, raising new concerns about how these chemicals are assessed for safety against serious diseases.

The peer-reviewed research, published in Environmental Health Perspectives, dug beyond the active ingredients in pesticides and examined the inactive ingredients that are often not subjected to the same level of safety scrutiny.

The study identifies chemicals associated with breast cancer risk. It does not establish that exposure to these pesticides causes breast cancer in people.

What Did The Researchers Find?

Of the 485 chemicals identified in pesticide formulations, only 145 were registered with the US Environmental Protection Agency (EPA) as active ingredients. The remaining chemicals were classified as inactive or 'inert' ingredients. These ingredients can serve different purposes, like helping pesticide ingredients spread, penetrate surfaces or become more absorbed.

The researchers argue that focusing primarily on active ingredients may overlook risks from the complete pesticide formulation.

“Our findings highlight a regulatory blind spot around so-called inert ingredients,” lead author Dr Jennifer Kay of the Silent Spring Institute said in a research release.

What Does “Inert” Mean?

An inert ingredient is generally considered 'inactive' as it does not target the pest the product is designed to kill. It does not mean that it has no biological effect on humans. According to the study's researchers, people are exposed to the entire pesticide formulation, not just the active ingredient in the pesticide.

The researchers identified around 4,000 inert ingredients approved for use by the EPA, including some PFAS, commonly known as 'forever chemicals.'

Pesticide Exposure

Pesticide exposure is not limited to agricultural workers or people living near farms. The chemicals identified in the study can also occur in products used around homes, including lawn treatments, flea and tick products and lice treatments. Pesticides can also enter the environment through food and drinking water.

The researchers found that 84 of the identified chemicals were detectable in the general US population based on data from the National Health and Nutrition Examination Survey, although they said this likely underestimates exposure because many of the compounds are not routinely tracked.

Pesticides & Breast Cancer Link

The researchers classified chemicals based on existing evidence linking them to breast cancer. That is different from demonstrating that pesticide exposure directly causes breast cancer in humans.

Breast cancer is a complex disease that involves multiple genetic, hormonal, environmental and lifestyle factors.

The study does, however, raise a question about whether the combined exposure to multiple chemicals is adequately considered during pesticide safety assessments.

The researchers noted that the EPA generally evaluates individual pesticide ingredients rather than the entire formulation or people's exposure to multiple pesticides.

The research comes as breast cancer rates, including among younger women, continue to rise in the US. According to the American Cancer Society data cited by The Guardian, breast cancer incidence has been increasing by about 1% a year, with a slightly faster increase among women under 50.

reaImagine developing a strange medical condition in which an injury or even a minor fall may trigger a process that may gradually turn muscles, tendons and ligaments into bone.

This is what fibrodysplasia ossificans progressiva (FOP), one of the world’s rarest genetic disorders, looks like.

The US Food and Drug Administration recently approved a new treatment option for FOP called Atebrioz (zilurgisertib), a once-daily pill developed by Mirum Pharmaceuticals.

Adults and children aged 12 years and above with FOP are eligible for this treatment. It is designed to reduce the formation of new bone outside the skeleton.

What Is Fibrodysplasia Ossificans Progressiva?

FOP is a rare genetic disease in which connective tissues like muscles, tendons and ligaments gradually turn into bone. The abnormal bone formation is known as heterotopic ossification, meaning bone starts to develop in places where it should not.

Over time, this can pose restriction in movement, cause deformities and lead to severe disability. The condition could affect quality of life significantly as well as shorten life expectancy.

FOP is usually diagnosed in childhood. According to Mirum, around 300 people in the US and about 900 worldwide are known to have the condition.

Why Does The Body Starts Making Bone In The Wrong Places?

FOP is caused by mutations in a gene involved in bone growth, especially the ACVR1 gene, which produces a protein called activin A receptor type-1, or ALK2. In people with FOP, this pathway becomes abnormally active. As a result, the body can start producing bone within soft tissues.

This process can occur in episodes called flare-ups. Trauma, surgery or other triggers can sometimes provoke inflammation and subsequent abnormal bone formation. The problem is that once mature bone has formed in these tissues, it can permanently restrict movement.

More About The New Drug

Atebrioz contains zilurgisertib, an oral drug that blocks ALK2, the protein that is abnormally active in most people with FOP and triggers bone formation outside the skeleton.

The aim is not to remove bone that has already formed. Instead, the treatment is designed to reduce the formation of new abnormal bone.

FDA’s approval was based on a randomised, placebo-controlled trial involving 63 people with FOP. Participants received either zilurgisertib or placebo for 24 weeks, followed by an extension period.

At week 24, patients receiving Atebrioz had an average 3.2 cm³ decrease in the volume of newly formed abnormal bone, compared to a 24.6 cm³ increase in the placebo group. The FDA said the difference supported the drug’s effectiveness in reducing new heterotopic ossification.

Symptoms & Treatment Of FOP

The disease can vary between individuals, but abnormal bone formation can progressively restrict movement. People with FOP may develop difficulty moving their neck, shoulders, spine, hips and other joints as new bone forms around them.

The condition can eventually affect mobility substantially. Extra bone formation can also interfere with everyday activities and contribute to severe disability.

Another characteristic feature is that people with FOP are often born with abnormalities of the big toes, which can help doctors recognise the rare condition early.

Atebrioz is not the first FDA-approved treatment for FOP. The FDA approved Sohonos (palovarotene) in 2023 as the first treatment for the disease.

More recently, the FDA approved Pasatru (garetosmab-grts) in August 2026, making Atebrioz the third FDA-approved treatment for FOP. The newer options differ in how they target the abnormal bone formation.
