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 the first time in nearly three decades, the US Food and Drug Administration (FDA) is proposing changes to nutrient requirements for infant formula. The proposed changes cover vitamins A and D, iodine and manganese under the Trump administration's Operation Stork Speed initiative, announced in March 2025.

The FDA’s first phase of a three-phase review covers eight of the 30 nutrients required in infant formula. It proposes revising requirements for four nutrients and reaffirming existing limits for the other four. It is also seeking public input on nutrients commonly added by manufacturers but not currently required. The agency is accepting comments for 120 days.

“Parents deserve confidence in every bottle they feed their baby,” US Health and Human Services Secretary Robert F. Kennedy Jr. said in a statement.

What Are The Proposed Changes?

The FDA's first phase covers eight nutrients. It proposes changes to four and retaining existing limits for the other four.

1. Iodine

• Minimum: Increased from 5 to 15 µg/100 kcal.
• Maximum: Reduced from 75 to 50 µg/100 kcal.

2. Manganese

• Minimum: Reduced from 5 to 1 µg/100 kcal.
• Maximum: A new limit of 50 µg/100 kcal.

3. Vitamin A

• Measurement unit changed from IU to micrograms of retinol activity equivalents (µg RAE).
• Minimum: Reduced from 250 IU (75 µg RAE) to 70 µg RAE/100 kcal.
• Maximum: Reduced from 750 IU (225 µg RAE) to 120 µg RAE/100 kcal.
• Only preformed vitamin A, not beta-carotene, will count towards the limits.

4. Vitamin D

• Measurement unit changed from IU to micrograms (µg).
• Minimum: Increased from 40 IU (1 µg) to 2 µg (80 IU)/100 kcal.
• Maximum: Increased from 100 IU (2.5 µg) to 3 µg (120 IU)/100 kcal.

The FDA also proposes updating formula labelling requirements to reflect the changes.

Which Nutrient Limits Will Remain Unchanged?

The FDA proposes retaining existing levels for:

• Chloride: 55–150 mg/100 kcal.
• Potassium: 80–200 mg/100 kcal.
• Selenium: 2–7 µg/100 kcal.
• Sodium: 20–60 mg/100 kcal.

What Do Parents Need To Know?

The FDA says formulas currently sold in the US remain safe for babies. The proposed changes are not prompted by safety concerns but aim to align standards with current scientific evidence.

Parents do not need to change the formula they currently use.

When Will The Changes Take Effect?

The FDA is reviewing all 30 nutrients in three phases. The first covers eight, with the remaining 22 to follow.

The final rule will take effect 60 days after publication in the Federal Register. Manufacturers will have three years from that date to reformulate and relabel their products.

This means the proposed changes will not appear on formula packaging immediately.

Dr Steven Abrams, a paediatrician and professor at the University of Texas' Dell Medical School, called the update overdue. He described the first phase as “really well done” and “very well thought-out”, CNN reported.

However, he said the phased approach means manufacturers could take several years to implement the changes.

“These changes that they're recommending today are not going to be something that'll show up on the can of formula potentially for several years,” Abrams said.

He identified the proposed vitamin D increase as the most consequential change in this phase.

Meanwhile, the FDA is also seeking input on making commonly added nutrients such as DHA, ARA and L-carnitine mandatory. These are not currently required in infant formula.

The Ebola outbreak in the Democratic Republic of Congo (DRC), officially declared a Public Health Emergency in May 2026, has surpassed 10,000 cases and is approaching 5,000 deaths, making it the fastest-growing Ebola outbreak in history.

Driven by the Bundibugyo Ebola virus, the outbreak has spread beyond the DRC to Uganda, Kenya and Nigeria, raising concerns about cross-border transmission. There is currently no licensed vaccine against this strain, although candidates are in development.

More than 1,000 children have died, accounting for over one-quarter of recorded fatalities, according to Save the Children.

“It's extraordinarily serious. Over 1,000 children have died of Ebola,” Greg Ramm, Save the Children's Country Director in the DRC, told the media.

“The world needs to start paying attention. We will break 15,000 deaths by the new year. And just because Ebola isn’t going to become a pandemic doesn’t mean it is not a global health security threat as well as a humanitarian disaster,” Dr Angela Rasmussen, a virologist, warned in a post on X.

Africa CDC Warns of Wider Global Risk

Africa CDC Director-General Dr Jean Kaseya has warned that the outbreak's unprecedented geographical spread could put countries beyond Africa, including the UK, at risk.

“The geographic extension of this outbreak is unprecedented,” he said, noting that three African regions had been affected. Drawing parallels with COVID-19, he warned: “We don’t want to see the UK and other countries become the hotspot,” The Guardian reported.

In response, the UK Health Security Agency's (UKHSA) Dr Sam Collins stressed that the risk to the UK remains low and that the country “is well prepared to respond safely and effectively to the risk of imported cases arising here”.

Genetic Analysis Links Kenya, Nigeria Cases to Congo

Scientists have linked Ebola viruses detected in Kenya and Nigeria to those circulating in Beni, eastern DRC, raising questions about a possible shared transmission chain or an unidentified source, Bloomberg reported.

“Genomic sequencing shows that the Ebola virus from Nigeria’s recently reported only imported case is highly similar to that from Kenya’s first imported case, differing by only one mutation,” Muhammad Ali Pate, Nigeria's Coordinating Minister of Health and Social Welfare, said in a post on X.

How Was The Genetic Analysis Conducted?

Scientists from four countries, led by Congolese virologist Jean-Jacques Muyembe, analysed 1,126 viral genomes after an Ebola case was detected in Abuja, Nigeria.

The Beni samples share a distinctive genetic signature, including a mutation absent from other sequenced viruses from Congo.

The viruses also lack genetic markers associated with Uganda's documented Ebola transmission chains from May and June, suggesting they did not descend from those previously identified outbreaks.

Researchers have yet to establish where the patients contracted the virus or whether they were infected through the same transmission chain. Genetic sequencing alone cannot prove direct transmission.

Travel Histories Point To Possible Congo Uganda Connection

Investigators are examining the patients' movements through Uganda during their potential exposure periods.

The Nigerian patient was in Uganda from September 15 to October 3 and developed symptoms three days after returning to Abuja. The Kenyan patient travelled from Congo through Uganda between October 1 and 3 before flying to Nairobi from Entebbe.

Both patients reportedly travelled on flights on October 3. Authorities are checking their travel records for possible overlap and tracing potentially exposed passengers.

Nigeria, Kenya Step Up Ebola Response

Nigeria has traced 62 contacts of the infected woman, NCDC Director-General Jide Idris said. Of these, 50 are in isolation, five are being monitored at home and seven remain unlocated.

Uganda recorded 20 confirmed cases and two deaths before declaring the outbreak over in June.

Kenya has reported nine cases and two deaths. Seven patients, including three family members and four healthcare workers, are receiving treatment and responding well. Authorities have traced all 135 contacts linked to the first case, according to official data.

As many as 500 newborns at Albany Medical Center in New York received hepatitis B vaccine doses that had been stored at an improper temperature in a refrigerator.

While the improperly stored doses pose no health threat to the infants who received them, the hospital said the storage lapse may have compromised the vaccines' effectiveness. The newborns may now need repeat doses to ensure they are protected against hepatitis B.

State Department of Health workers reviewing refrigeration logs ahead of a hospital site visit found that the vaccines had been stored below the manufacturer's recommended temperature range, The Times Union reported.

The improper storage may have affected the vaccines' effectiveness, meaning the infants who received them may not have developed adequate protection against hepatitis B and could need repeat doses.

Albany Medical Center said it has sent letters to affected parents and their children's doctors explaining that repeat doses may be necessary. A hospital spokesperson added that the Center has also apologised for the error and has implemented additional safeguards.

Hepatitis B vaccines require strict temperature control to maintain their effectiveness. Immunize.org recommends storing all hepatitis B-containing vaccines between 2°C and 8°C (36°F and 46°F) and cautions against freezing them.

According to the Children's Hospital of Philadelphia, vaccine storage errors must be assessed individually in consultation with health authorities. Doses found to be expired or nonviable generally cannot be counted as valid, and non-live vaccine doses may need to be repeated as soon as possible.

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

Newborns typically receive their first hepatitis B vaccine dose shortly after birth, often before they leave the hospital. The American Academy of Pediatrics recommends that newborns receive the first dose within 24 hours of birth, followed by a second dose within two months. School-aged children must receive three doses in total.

The vaccine protects against a virus that can cause serious liver disease. In New York, about 90% of children complete the full three-dose vaccine series before age three, according to Kaiser Family Foundation figures cited in The Times Union report.

What is Hepatitis B?

Hepatitis B is a viral infection that affects the liver and spreads through infected blood and certain bodily fluids, including during childbirth.

An infection acquired during infancy is particularly concerning because it is more likely to become chronic. Over time, chronic hepatitis B can lead to cirrhosis, liver failure or liver cancer.

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 for hepatitis B.

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.
