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.

Amid the scare of hantavirus infection, US health officials informed that they are investigating a potential case in an Illinois resident.

The Illinois Department of Public Health (IDPH) noted that the incident is not linked to the MV Hondius cruise ship outbreak.

MV Hondius had 18 American nationals, and all have been medically evacuated back to the US. While 16 people are in Nebraska at the nation's only national quarantine unit, two people are being monitored in Atlanta.

In a statement, the IDPH said that the person “lives in Winnebago County, has not travelled internationally, and has not come in contact with individuals associated with the MV Hondius outbreak”.

Officials suspect that the possible hantavirus infection in the Illinois person to be a case of the North American strain of the virus while cleaning a home where rodent droppings were present.

“Unlike the Andes strain of Hantavirus responsible for the cruise outbreak, the North American strains are not known to spread from person to person. The risk of contracting Hantavirus of any kind remains very low for Illinois residents,” the officials said.

However, they added that the CDC is conducting additional testing to confirm that the resident is positive for Hantavirus. CDC staff told IDPH its confirmatory test result could take up to 10 days to complete.

Hantavirus Cases In The US

Excluding this latest potential case, Illinois has had 7 positive cases of Hantavirus since 1993, most recently in March 2025.

Since surveillance began in 1993, the US has recorded 890 cases of Hantavirus over 30 years (1993-2023)

The Hantavirus strain most commonly seen in the US is caused by exposure to rodent droppings and is NOT contagious from person to person.

The rodent species (long-tailed pygmy rice rat) known to carry the Andes strain of the virus in South America does not live in the U.S.

First Case Of Hantavirus Diagnosed In Israel

Earlier, a case of hantavirus was also reported from Israel, that was not linked to the MV Hondius ship.

The case in Israel, reported by the local newspaper Maariv, is believed to have been infected during a stay in Eastern Europe several months ago. It is reportedly not linked to the ongoing outbreak linked to the MV Hondius cruise ship in the Atlantic Ocean.

The patient underwent an antibody test after the symptoms appeared, which showed exposure to hantavirus, the report said. A PCR (polymerase chain reaction) test was then conducted to detect the virus’s genetic material, confirming the infection, the report said.

The patient was said to be in stable condition, not in need of intensive care or strict isolation, and was being kept under medical observation.

Details about the patient and the medical center where the diagnosis was made could not yet be published, but have been reported to the country's Health Ministry.

Hantavirus is primarily transmitted through contact with infected rodents or exposure to their urine, droppings, and saliva, though rare cases of person-to-person transmission have also been reported.

According to the World Health Organization (WHO), 11 cases — including three deaths — have been confirmed so far. However, additional suspected and confirmed cases are continuing to emerge across countries.

“At the moment, there is no sign that we are seeing the start of a larger outbreak,” said Tedros Adhanom Ghebreyesus, WHO Chief, in the latest media briefing.

However, he said that the situation could still change.

“Given the long incubation period of the virus, we might see more cases in the coming weeks,” he said.

Polycystic Ovary Syndrome (PCOS), a condition affecting more than 170 million women worldwide, has now been officially renamed Polyendocrine Metabolic Ovarian Syndrome (PMOS), according to a global study published today in The Lancet.

The new name reflects a major shift in understanding the condition — from being viewed primarily as a gynecological disorder to being recognized as a complex, multisystem condition affecting several aspects of health.

The new term PMOS acknowledges that the condition involves:

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

“For too long, the narrow definition of PCOS has overlooked its metabolic and hormonal complexity, leaving many patients undiagnosed or misunderstood,” Cree added.

Why Was PCOS Renamed To PMOS?

Calls to rename PCOS date back to the 1990s and early 2000s. In 2012, the U.S. National Institutes of Health (NIH) recommended a name change after experts concluded that the term PCOS was misleading and confusing for both patients and healthcare providers.

“The name focuses on a criterion — polycystic ovarian morphology — which is neither necessary nor sufficient to diagnose the syndrome,” NIH experts wrote in the report.

Although PCOS has long been understood as a metabolic condition, experts said the name inaccurately narrowed its scope and overemphasized ovarian cysts and fertility issues.

This often led to:

• Delayed diagnoses
• Fragmented care
• Stigma
• Missed opportunities for early intervention

How Was The Name Change Decided?

The renaming process involved consultations with thousands of patients and healthcare professionals across the world.

The effort was supported by 56 academic, clinical, and patient organizations.

Experts said the transition from PCOS to PMOS will occur over the next three years through a phased global implementation strategy.

What Does PMOS Mean?

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.

In simple terms, PMOS is a hormonal and metabolic condition that can affect periods, fertility, skin, mood, weight, and long-term health.

Experts said the new terminology intends to:

• Reflect the condition’s hormonal complexity
• Acknowledge its strong metabolic and cardiometabolic effects
• Continue emphasizing ovarian involvement without over-focusing on fertility

According to the study, PMOS could also:

• Promote earlier and more accurate diagnosis
• Support more holistic, patient-centered care
• Reduce stigma associated with fertility-focused terminology
• Expand research into metabolic and systemic impacts

Hantavirus cases have climbed to 11, including three deaths, WHO Director-General Tedros Adhanom Ghebreyesus said today.

During a media briefing on hantavirus, Tedros stated that all eleven cases are among passengers or crew members onboard the MV Hondius.

“Nine of the eleven have been confirmed as Andes virus, and the other two are probable,” he added.

All suspected and confirmed cases have been isolated and managed under strict medical supervision, minimizing any risk of further transmission.

Tedros said individual countries were now responsible for their citizens after the evacuation, adding: “I hope they will take care of the patients and the passengers, helping them and also protecting their citizens as well. That’s what we expect.”

Will Hantavirus Become A Public Health Threat?

Noting that “at the moment, there is no sign that we are seeing the start of a larger outbreak,” Tedros said the situation could still change.

“Given the long incubation period of the virus, it’s possible we might see more cases in the coming weeks,” he said.

Acclaimed vaccine scientist Prof. Peter Hotez from the Texas Medical Center (TMC) also said more cases could emerge, but ruled out the risk of a major epidemic.

“We might see additional cases, but I don't think this will be a major epidemic beyond the obvious human tragedy of those who lost their lives, and possibly a few others who could still get very sick,” he said in a post on social media platform X.

“New World hantavirus infections are rough stuff. Once symptoms begin, the resulting cytokine storm and ARDS means there's not much of a window before getting patients into an ICU, and often on ECMO (extracorporeal membrane oxygenation), which requires a high level of skill,” Prof. Peter said.

He also linked increasing zoonotic spillovers and rising arthropod-borne illnesses to “climate change pushing animal reservoirs to explore new habitats, together with deforestation and urbanization.”

“It's animals and vectors closer to humans and people coming closer to animals and vectors,” he added.

“I don't think this particular hantavirus outbreak will accelerate much beyond where it is now, but that's not the point.”

Dutch Hospital Quarantines 12 Healthcare Workers

Meanwhile, Radboud University Medical Center (Radboudumc) in the Netherlands has placed 12 employees in quarantine for six weeks as a precaution after incorrect procedures were followed while caring for a hantavirus-infected patient from the Dutch cruise ship.

The hospital said on Monday that the issue involved procedures for drawing and processing blood samples, as well as the disposal of the patient's urine, according to Xinhua news agency.

“This blood was processed according to standard procedure. Due to the nature of the virus, this blood should have been processed according to a stricter procedure,” Radboudumc said in a statement, without specifying what the stricter measures should have entailed.
