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.

Ugandan health authorities have confirmed an isolated case of Marburg virus disease (MVD) in a young child who died from the highly infectious viral hemorrhagic fever.

The case comes as Uganda is already battling an outbreak of Ebola virus disease, another viral hemorrhagic fever.

According to the Africa Centres for Disease Control and Prevention (Africa CDC), the Marburg infection was detected during surveillance for the ongoing Ebola outbreak, Reuters reported.

Health officials said no contacts of the child have developed symptoms, and there are currently no active Marburg cases in the East African nation.

While a spokesperson for Uganda's Ministry of Health said they were unaware of a Marburg outbreak, the World Health Organization (WHO) confirmed it was notified of the case on June 30.

"WHO has requested further information and is supporting the local response, including case investigation, active case finding, contact tracing and community engagement," a WHO spokesperson said.

Child Death Raises Questions

According to Africa CDC, the case was identified in Kyegegwa district in western Uganda in a 1½-year-old child who later died.

"Africa CDC is engaging the Government of Uganda through official public health channels on reports concerning Marburg virus disease. At this stage, we cannot confirm reports of any additional case," Africa CDC spokesperson Saran Koly said.

"Africa CDC stands ready to support verification, risk assessment and response readiness as needed."

Uganda last reported a Marburg outbreak in 2017 and has experience of managing three previous outbreaks. However, responding to a potential Marburg outbreak while simultaneously battling Ebola could complicate public health efforts.

So far, Uganda has reported a total of 20 cases of the rare Bundibugyo species of Ebola, including two deaths. Of these, 15 cases were imported from the Democratic Republic of Congo.

Marburg Infection In Child 'Unusual'

The child's age has prompted questions about how the infection occurred. Abraar Karan, a global health physician and researcher at Stanford University, said infection in a toddler is unusual.

"Quite unusual -- I would suspect transmission from someone else, but there are some less-likely scenarios in which spillover could still have happened directly to a toddler," he wrote in a post on X.

What Is Marburg Virus Disease?

Marburg virus disease belongs to the same virus family as Ebola and can cause severe hemorrhagic fever. It was first recognized in 1967. MVD has a high case fatality rate ranging from 32 per cent to 88 per cent. It is transmitted to humans after a spill-over event from a wildlife reservoir such as Rousettus aegyptiacus fruit bats or their feces or contact with infected primates

Once a person is infected, the virus spreads through direct contact with the blood, bodily fluids or contaminated materials of an infected person.

Common Signs and Symptoms

Symptoms usually begin suddenly and include:

• High fever
• Severe headache
• Muscle pain
• Diarrhea
• Vomiting
• Abdominal pain
• Extreme weakness

In severe cases, patients may develop internal and external bleeding, organ failure and shock, which can be fatal.

How Can Marburg Virus Be Prevented?

There is currently no approved vaccine or specific treatment for Marburg virus disease, although several vaccines and therapies are under development. Early supportive care can improve survival.

Health authorities recommend:

• Avoid direct contact with the blood and bodily fluids of infected people.
• Avoid handling the bodies of people who died from Marburg virus disease.
• Avoid close contact with bats and wild animals, and do not handle bushmeat.

What sounds like science fiction is now a scientific reality. Researchers at the University of Minnesota have created the world's first synthetic cell built entirely from non-living chemical components that can eat, grow and reproduce—the defining characteristics of life.

The lab-made cell, named SpudCell, completes an entire life cycle and could help scientists better understand how life works while opening new possibilities in medicine, biotechnology and manufacturing.

"We've replicated in chemistry what only used to be possible in biology: the complete set of behaviors of a cell," said Associate Professor Kate Adamala. "It proves that the most fundamental functions of life... do not need a mysterious, magical spark."

The findings have been published as a preprint and have not yet been peer-reviewed.

"We have demonstrated key milestones towards construction of synthetic life: a complete cell cycle, including growth and division, and selection, in minimal cells with known identity of all components. This can serve as a chassis for further optimization of synthetic cells undergoing Darwinian evolution, advancing the field towards robust artificial life," the researchers wrote.

What Is SpudCell?

SpudCell is a synthetic cell assembled entirely from purified, non-living chemical components rather than modified living cells.

It contains:

• 36 purified enzymes
• A 90,000-base-pair genome spread across nine DNA molecules
• A lipid membrane

What Can SpudCell Do?

Replicate a Cell's Life Cycle

SpudCell can perform the essential functions of living cells, including:

• Feeding and acquiring resources
• Growing
• Replicating its genome
• Dividing
• Passing on genetically encoded traits

Unlike natural cells, SpudCell divides without a cytoskeleton. Instead, membrane-binding proteins build up on its surface until mechanical stress causes the membrane to split.

Researchers also engineered a faster-growing version of the cell. Within five generations, it outcompeted the original, demonstrating selection and evolution-like behaviour in a fully synthetic chemical system.

SpudCell: Why Is It Significant?

Scientists previously estimated that the smallest possible genome for a living cell would be around 113 kilobase pairs (kbp). SpudCell functions with just 90 kbp, making it one of the simplest known cell-like systems.

Its modular DNA design also allows researchers to program different cellular functions independently, making future synthetic cells easier to engineer.

SpudCell: Potential Applications

Researchers stated that synthetic cells could eventually perform chemical reactions beyond the reach of conventional industrial processes.

Possible applications include:

• Designing highly precise medicines
• Developing new drug molecules using amino acids not found in nature
• Producing advanced materials through biological manufacturing

"We could see materials that are grown, rather than synthesized... SpudCell provides, for the first time, a truly engineerable platform," the authors said.

SpudCell: Next steps

The researchers noted that in next steps they aim to combine the cell's multiple DNA molecules into a single stable genome, add more molecular machinery and develop common engineering standards before synthetic cells can be widely used.

"This work is just the beginning," Adamala said. "We are showing it's possible to engineer the basic functions of the cell."

Experts Urge Caution

While calling the work remarkable, Professor John Dupré of the University of Exeter questioned whether synthetic cells would outperform genetically modified bacteria in producing drugs, food, fuel and other materials.

He also argued that synthetic cells lack an important feature of living organisms—their relationships with other life forms.

"What is missing... is the relational aspect of life, which has become clear in the growing realization that life is almost universally symbiotic," he said.

An 11-year-old boy in Canada succumbed to rabies after waking up to find a bat on his face. The incident highlighted how even seemingly harmless contact with the animal, with no bites, can lead to a fatal infection if preventive treatment is not started in time, which is crucial in rabies.

Canada Boy Dies Of Rabies

The case was published in the Canadian Medical Association Journal (CMAJ). The incident occurred during the summer of 2024 while the boy was staying at a cottage in northern Ontario.

According to the report, he woke up with a bat on his face and instinctively swatted it away. His father caught the bat in a cooking pot and released it outdoors. Since there were no visible bite or scratch marks and the bat did not appear to behave aggressively, the family did not suspect rabies and seek medical attention.

However, 19 days later, the child developed facial tingling and numbness, followed by swelling, vomiting, and loss of appetite.

He was treated for a suspected viral infection initially, but his condition rapidly worsened. He went on to develop difficulty swallowing, fever, slurred speech, confusion, and visual hallucinations before being diagnosed with rabies. Despite being admitted in pediatric intensive care, he died after 17 days of admission.

The authors of the case report said the family agreed to share the child's story to raise awareness about rabies and the importance of seeking immediate medical evaluation after any direct contact with a bat, even if there are no visible bite marks.

Bat Exposure Is Risky Even If There Are No Bite Marks

Because of this, public health authorities recommend seeking medical advice after direct contact with a bat.

Immediate treatment with rabies vaccination is highly effective in preventing the disease if administered before symptoms develop. Once rabies symptoms appear, it is almost always fatal.

Rabies Remains One Of The Deadliest Infections

Human rabies cases are rare in Canada. Since 1924, only 28 human rabies cases have been reported in the country, and the Ontario child's death marked the province's first human rabies case since 1967.

While dogs remain the primary source of human rabies' deaths globally, bats are the leading source of human rabies infections acquired in North America.

According to the World Health Organization, rabies causes an estimated 59,000 human deaths every year, with the vast majority occurring in Asia and Africa.

The authors of the CMAJ case report stressed that healthcare providers should carefully assess any history of direct bat contact and consider post-exposure prophylaxis when appropriate.

They noted that early treatment is nearly 100% effective in preventing rabies before symptoms begin, making timely medical evaluation critical after any potential exposure.
