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.

The National Health Service (NHS) has approved teplizumab for people with early-stage type 1 diabetes in England and Wales.

Teplizumab (sold under the brand names Tzield and Teplizumab) is manufactured by French drug maker Sanofi and is the world's first immunotherapy to target the root cause of type 1 diabetes and slow its progression.

It will be made available on the NHS in England and Wales as clinical trial evidence reviewed by the National Institute for Health and Care Excellence (NICE) showed that teplizumab can delay the onset of symptomatic type 1 diabetes by an average of nearly three years.

“This is a genuinely exciting recommendation. For the first time, we have a treatment that can give people diagnosed at an early stage of type 1 diabetes precious extra time before they need to manage the full demands of the condition,” said Helen Knight, director of medicines evaluation at NICE.

Who Is Eligible for Teplizumab?

Teplizumab is used to delay the onset of stage 3 type 1 diabetes in children aged 8 years and older, and adults, with stage 2 type 1 diabetes.

In stage 1 type 1 diabetes, there are no symptoms, and blood sugar levels are normal, but blood tests show the immune system has begun attacking the insulin-producing cells in the pancreas.

At stage 2, the immune attack has progressed further. There are still no symptoms, but blood tests show early changes in blood sugar levels, indicating a high risk of developing symptomatic diabetes.

Because stage 2 type 1 diabetes has no symptoms, specific tests are needed to diagnose it. There is currently no national screening program. But people are most likely to be identified through:

• Research studies such as ELSA and T1DRA, which screen children and young people aged 2 to 17.

• Testing because of an increased risk, such as having a parent, sibling or child with type 1 diabetes.

• Testing for other medical reasons, including concerns about blood sugar levels.

“Around 1,100 people could be eligible for treatment in the first year, with approximately 555 expected to take it up. From year three, the eligible population is expected to stabilise at around 820 people annually, with approximately 490 expected to receive treatment,” as per NICE.

How Does Teplizumab Work?

Teplizumab helps regulate the immune system by attaching to a protein called CD3 on the surface of immune cells responsible for attacking insulin-producing cells. This slows damage to the pancreas and delays the onset of the disease.

Evidence for teplizumab comes from the TN-10 clinical trial, which followed 76 children aged 8 years and older and adults with stage 2 type 1 diabetes who had a close family member with the condition. Of the participants, 44 received teplizumab and 32 received a placebo.

Teplizumab delayed the onset of symptomatic type 1 diabetes by approximately 32 months.

How Is Teplizumab Administered?

Teplizumab is given through a drip into a vein once a day for 14 consecutive days. Each infusion takes at least 30 minutes, with the dose gradually increased during the first few days. It is a one-time treatment course.

Patients will need to attend hospital every day during the treatment period, including weekends. The NICE committee noted that daily travel may be difficult for some people because of cost or practical considerations.

Sanofi has agreed a commercial arrangement with NHS England, meaning teplizumab will be available to the NHS at a confidential discounted price.

The Ebola outbreak in the Democratic Republic of Congo (DRC) is worsening, with confirmed cases rising to 1,048 and the death toll reaching 267, according to government data.

The country has also reported 112 recoveries, while contact tracing coverage has improved to 70.8%. However, significant gaps remain. The World Health Organization (WHO) estimates that at least 95% of contacts must be traced to effectively contain an outbreak.

The outbreak caused by the Bundibugyo strain, with no vaccine or anti-viral, is spreading rapidly, even as response measures are being intensified.

"The outbreak remains serious and is evolving very fast. However, I have seen a response that is growing stronger every day," said Marie-Roseline Belizaire, WHO Regional Emergencies Director for Africa, speaking to reporters in Bunia, the epicenter of the outbreak.

Suspected Cases In Israel Test Negative

Meanwhile, Israel's Health Ministry said test results for two men hospitalized on suspicion of Ebola infection were negative.

The ministry stressed that no confirmed Ebola case has been diagnosed in Israel and advised the public to avoid non-essential travel to areas experiencing active outbreaks.

In addition, it urged travelers returning from Ebola-affected regions who develop fever or unusual symptoms within 21 days of their return to stay home and avoid contact with others.

Nearly 3 Million Children at Risk

UNICEF has warned that nearly 3 million children and adolescents face growing risks in eastern DRC.

According to the UN agency, an estimated 2.95 million children and adolescents aged 18 and under — representing 54% of the population across 31 affected health zones — are at risk from both Ebola and the disruption of essential services.

In Ituri province alone, Ebola has left more than 130 children orphaned, creating an urgent need for protection and care.

“Our teams in Ituri have met children who have lost their mothers, and in some cases both parents, to Ebola," said UNICEF Executive Director Catherine Russell. "Children are trying to make sense of the threat while surrounded by rumors and online misinformation.”

Although the situation remains fluid, children and adolescents account for approximately 15% of confirmed Ebola cases and more than 25% of confirmed deaths in eastern DRC as of June 19.

Children and adolescents with confirmed Ebola are almost twice as likely to die as adults, highlighting the disproportionate impact of the outbreak on younger populations.

Children Affected In Uganda

In Uganda, 20 Ebola cases and two deaths have been confirmed among individuals who travelled from the DRC seeking testing and treatment.

Children have also been affected. One child has tested positive for Ebola, while 19 others are under quarantine monitoring, the UNICEF said.

“Children are especially vulnerable because they depend on caregivers and cannot distance themselves from a sick parent or sibling in the same way that an adult can. To better protect children, we need sustained access, and the resources needed to reach every affected community," Russell added.

Marketa Vondrousova, the 2023 Wimbledon singles champion, has been banned from professional sport for four years after refusing an anti-doping test.

According to an independent tribunal, the 26-year-old provided “no compelling justification” for declining to provide a sample after being notified at her home by a doping control officer in December.

“We recognize that this is a significant ban. And the reason for that is that you can’t have an anti-doping system where a player is in a better place by refusing to take a test than they would be by taking the test and testing positive,” said Karen Moorhouse, chief executive of the International Tennis Integrity Agency (ITIA).

“That feeds into the structure of the doping rules that provides for a starting point of a four-year ban for refusing to take a test, the same as a starting point for testing positive,” she added.

The Czech player said in April that she feared for her safety when the officer called and claimed the officer had failed to follow protocol.

Vondrousova reached the French Open final in 2019, won an Olympic silver medal in 2021, and achieved a career-high ranking of No. 6.

“I have never doped, I have never had a positive test. Throughout my entire career, I have undergone countless anti-doping controls and have always stepped onto the court with a clear conscience. I cannot say what comes next. For the first time in my life, I do not have a plan,” she said in a statement.

She is suspended from all professional events until June 21, 2030, but has the right to appeal the decision to the Court of Arbitration for Sport (CAS).

According to Vondrousova, the doping control officer did not adhere to the rules by approaching her outside the hour she had designated under the whereabouts rules. During the hearing, Vondrousova said stress and poor mental health had affected her decision-making, in addition to her safety concerns.

How Doping Tests Work

Doping control (testing) is one tool that Anti-Doping Organizations (ADOs) use to level the playing field and protect clean sport.

As per the World Anti-Doping Agency (WADA), athletes playing at the national or international level can be subject to doping control and can be tested anytime or anywhere.

Here's how the process works as per WADA:

• Notification: A doping control officer (DCO) informs the athlete that they have been selected for testing.
• Reporting: The athlete must report to the doping control station, with limited exceptions such as medal ceremonies.
• Sample Selection: The athlete chooses a urine collection vessel or a blood collection kit.
• Sample Collection: Urine collection is witnessed by a DCO or chaperone. Blood samples are collected by a blood collection officer.
• A and B Samples: The sample is divided into A and B bottles. The B sample can be tested if the A sample returns a positive result.
• Sealing: The athlete seals the sample bottles.
• Quality Check: Urine samples are checked to ensure they meet laboratory standards. Additional samples may be required if they are too dilute.
• Documentation: The athlete completes a Doping Control Form (DCF), recording relevant information and receiving a copy.
• Laboratory Testing: The sealed sample is sent to a WADA-accredited laboratory for analysis, with the athlete's identity kept anonymous.
