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.

India continues to battle one of the world's highest burdens of preterm births. Early identification of critically ill newborns remains crucial for improving survival rates, particularly in hospitals with limited resources.

A new Indian study says that Clinical Risk Index for Babies-II (CRIB-II) score is an effective tool for predicting mortality risk among preterm newborns admitted to neonatal intensive care units (NICUs).

The research, conducted by doctors at JK Lone Hospital in Jaipur and published in the International Journal of Paediatric Research, can help preterm babies receive faster treatment and enable better use of neonatal intensive care resources.

What Is The CRIB-II score?

• Birth weight
• Gestational age
• Baby's body temperature at admission
• Blood acid-base status
• Sex of the baby

The higher the score, the greater the risk of severe illness or death.

What Did The Study Find?

Researchers studied 181 premature newborns admitted to the tertiary care hospital. The babies had an average gestational age of 28.88 weeks and an average birth weight of 1.01 kg. The analysis showed a clear relationship between CRIB-II scores and outcomes:

• 0 to 5: Low risk
• 6 to 10: Moderate risk
• 11 to 15: High risk
• Above 15: Very high risk

Babies with higher CRIB-II scores were significantly more likely to die than those with lower scores, suggesting that the scoring system can accurately identify newborns requiring immediate intensive care.

Dr. Yogesh Yadav, paediatric specialist and one of the study's researchers, said the score enables doctors to make critical treatment decisions within the first few hours after admission.

"If we calculate the CRIB-II score at the time of admission, we can understand the seriousness of the baby's condition. This helps doctors decide the right treatment direction early and increases the chances of saving the baby."

He added that the score is more than simply a predictor of mortality. "CRIB-II is not just a score to predict death risk, but an important scientific tool for decision-making in the NICU. In the first few hours, we can identify which newborn is at high risk."

The researchers believe the scoring system could be particularly valuable across India, where NICUs often face shortages of beds, ventilators and trained neonatal staff.

According to Dr. Yadav: "When beds, ventilators or trained staff are limited, babies with higher scores can be given priority in the NICU. It also helps in deciding which newborns need to be referred immediately to higher centres."

The score can also improve communication with families by helping clinicians provide clearer information about a baby's condition and expected prognosis.

"Through CRIB-II, we can give parents a clearer and more accurate understanding of the baby's condition, possible outcomes and treatment needs."

Although CRIB-II has been used internationally for years, the latest Indian findings add to growing evidence supporting its use in neonatal intensive care.

A newly identified brain protein may help slow the progression of Alzheimer's disease, according to new research that sheds light on how the disease spreads through the brain.

Scientists have found that a protein called SORLA acts as a natural defense against the toxic tau protein, limiting the brain damage that causes memory loss and cognitive decline.

The findings, published in Nature Neuroscience, suggest that boosting SORLA activity could become a therapeutic strategy.

SORLA Can Help Regulate Tau

The study found that SORLA regulates how tau proteins move between neurons. While amyloid plaques have long dominated Alzheimer's research, mounting evidence suggests that the spread of tau in the brain is more closely linked to the symptoms of Alzheimer's.

When SORLA levels were low, toxic tau spread more easily from one brain cell to another. In contrast, increasing SORLA significantly reduced tau accumulation, protected brain tissue from shrinking, and preserved memory in mouse models of Alzheimer's disease.

"Our findings identify SORLA as a potent endogenous suppressor of tau propagation," the researchers wrote, adding that enhancing SORLA function "could represent a promising therapeutic strategy for limiting the progression of Alzheimer's disease."

How Can This Discovery Help?

Current Alzheimer's drugs like Leqembi primarily target amyloid-beta plaques. Although these treatments can slow disease progression in some patients, they do not directly stop the spread of tau, which drives the loss of brain cells which worsens dementia.

The discovery of SORLA offers a different approach by targeting one of the disease's most dangerous aspects: tau propagation.

Can This Lead To Effective Alzheimer's Treatments?

The SORLA findings were demonstrated primarily in laboratory models, meaning much more research is needed before therapies can be tested in people.

However, researchers say identifying the brain's own protective mechanisms provides an important roadmap for developing treatments that not only remove harmful proteins but also prevent them from spreading.

If future studies confirm these findings in humans, therapies that boost SORLA could potentially be combined with existing anti-amyloid medicines to slow Alzheimer's progression more effectively.

The SORLA discovery comes amid growing momentum in tau-based Alzheimer's research.

Just this month, researchers reported encouraging results from diranersen, an experimental therapy designed to reduce production of the tau protein itself.

In a mid-stage clinical trial involving around 400 people with early Alzheimer's disease, the drug lowered tau levels and showed signs of slowing cognitive decline in some participants, although larger studies are needed to confirm its effectiveness.

What Is SORLA?

SORLA (Sorting Protein-Related Receptor with LDLR Class A Repeats) is a receptor protein naturally present in brain cells.

Scientists have known for years that low SORLA levels are associated with an increased risk of Alzheimer's disease because the protein helps process amyloid precursor protein.

Why Is Tau Considered Dangerous?

Tau is a normal protein that helps stabilize the internal structure of nerve cells. In Alzheimer's disease, however, tau becomes abnormally folded and forms neurofibrillary tangles.

These tangles spread through interconnected brain regions, disrupting communication between neurons, and eventually causing them to die.

Researchers believe the progression of tau pathology closely mirrors the progression of memory loss and cognitive impairment seen in Alzheimer's patients.

Women with polyendocrine metabolic ovarian syndrome (PMOS)—formerly known as polycystic ovarian syndrome (PCOS)—face a significantly higher risk of heart attacks, strokes, and other cardiovascular diseases, according to a large study published in The Lancet Obstetrics, Gynaecology & Women's Health.

PMOS affects an estimated 10–13% of women of reproductive age. Researchers analyzed data from more than 2 million women and found that those with PMOS had a substantially higher risk of serious cardiovascular events, even after accounting for established risk factors such as obesity, diabetes, high blood pressure, smoking, and high cholesterol.

The findings, by researchers from the University of Pennsylvania and the University of Rochester, suggest that PMOS should be recognized not only as a reproductive health condition but also as a major cardiometabolic disorder, underscoring the need for routine cardiovascular monitoring in affected women.

Women with PMOS were significantly more likely to develop atherosclerotic cardiovascular disease (ASCVD), including heart attacks and strokes.

After adjusting for traditional cardiovascular risk factors, researchers found that women with PMOS were:

• 2.5 times more likely to experience a heart attack or stroke.
• 3.4 times more likely to have a transient ischemic attack (TIA), or "mini-stroke."
• Nearly four times more likely to develop peripheral artery disease (PAD), in which narrowed arteries reduce blood flow to the limbs.

"Our work shows that it is imperative for clinicians to closely track and evaluate cardiovascular health in patients with PMOS," said Dr. Anuja Dokras, senior author of the study and Founders Professor of Women's Health at the University of Pennsylvania.

She advised women with PMOS to lower their cardiovascular risk by:

• Avoiding smoking
• Staying physically active
• Maintaining a healthy weight
• Regularly monitoring blood pressure, cholesterol, and blood sugar

What Is PMOS?

PMOS is the new name for PCOS, adopted following an international consensus announced in May 2026 by the World Health Organization, the Endocrine Society, and other leading organizations.

The new name reflects the understanding that the condition affects multiple body systems—not just the ovaries. PMOS is a complex hormonal and metabolic disorder linked to an increased risk of:

• Infertility
• Type 2 diabetes
• Endometrial cancer
• Cardiovascular disease

The condition can affect:

• Endocrine health
• Metabolic health
• Reproductive health
• Dermatological health
• Psychological health

Why Was PCOS Renamed?

Experts said the term PCOS was misleading because many patients believed it referred to ovarian cysts, whereas the condition is characterized by increased ovarian follicles rather than true cysts.

"My patients often assumed they had cysts on their ovaries, but instead, people with PMOS have increased follicles that can resemble cysts," said Dr. Dokras. "The effects of PMOS extend far beyond gynecologic health. The new name better reflects the multiple hormonal and metabolic systems involved and encourages more comprehensive care."

The new name aims to explain the condition more accurately and comprehensively.

• Polyendocrine means it affects multiple hormones in the body.
• Metabolic refers to issues linked to weight, insulin, blood sugar, and heart health.
• Ovarian highlights its impact on ovulation and reproductive health.
• Syndrome refers to a group of symptoms occurring together.
