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.

Female high school students in the United States had lower overall cardiovascular health scores than male students, with mean scores of 64.2 and 66.2, respectively, according to a nationwide survey by the US Centers for Disease Control and Prevention (CDC).

The findings, based on the American Heart Association’s Life’s Essential 8 framework, showed that female students had lower mean scores for physical activity and sleep health but higher, more favorable BMI scores than male students.

Lower physical activity and sleep health scores were also observed among students in higher grades, while nicotine exposure scores were lower among students in higher grades.

The 2025 biennial Youth Risk Behavior Survey included 10,710 students in grades 9–12. Of these, 5,192 had complete data for all five cardiovascular health measures: physical activity, diet, sleep health, body mass index (BMI), and nicotine exposure.

The findings, published in the CDC’s Morbidity and Mortality Weekly Report, showed that approximately 21% of students had high overall cardiovascular health scores, while 61% had moderate scores and 18% had low scores.

The prevalence of high overall scores was lower among female students and those in grades 10–12 than among male students and ninth-graders, respectively. Overall, approximately four in five students had low or moderate scores across the five assessed cardiovascular health measures.

Cardiovascular diseases (CVDs) are the leading causes of mortality in the US, and many CVD risk factors emerge in childhood and adolescence. Adolescence is a crucial period during which health behaviors develop and persist into adulthood.

A March 2026 study published in the European Journal of Preventive Cardiology suggested that even small, combined improvements in daily habits may benefit cardiovascular health.

Sleeping an additional 11 minutes, engaging in five more minutes of moderate-to-vigorous physical activity, and eating an extra quarter-cup of vegetables daily were associated with a 10% lower risk of heart attacks, strokes and other serious cardiovascular problems compared with less healthy habits.

Sleep is particularly important during adolescence, when the body and brain undergo significant developmental changes. Adequate sleep supports physical recovery, immune function, concentration and emotional well-being.

Teenagers generally need eight to 10 hours of sleep each night. However, schoolwork, extracurricular activities and screen time can interfere with sufficient rest. Research has also linked insufficient sleep with less healthy food choices and a greater tendency to eat later at night.

Elsie Taveras, a pediatrician at Mass General Brigham, highlights the importance of adequate sleep in reducing the risk of chronic conditions, including obesity and cardiovascular risk factors. Children from racial minority and lower-income households may face additional barriers to healthy sleep.

“Sleep health is something we need to pay attention to, and that we counsel teenagers and their families about,” Taveras said.

“We’ve found that shorter sleep duration and lower sleep quality in children and adolescents are associated with a higher risk of obesity and risk factors for heart disease. These are substantial effects that can affect children for years to come,” she added.

Dr Rachna Shroff, an Indian-American cancer researcher at the University of Arizona, has died at the age of 47 from an aggressive form of cancer she had spent her career studying, the university announced.

Earlier this year, Shroff, associate director of clinical investigations at the University of Arizona Cancer Center, was diagnosed with incurable, terminal adenocarcinoma, a cancer that develops in glandular cells lining certain organs.

Dr Rachna Shroff’s Cancer Diagnosis

Dr Rachna first noticed a swollen lymph node in May. By the end of the month, the cancer had spread elsewhere in her body, and tests suggested it had likely originated in her stomach or intestine.

Her medical team initially suspected lymphoma, a type of blood cancer. Further testing later confirmed terminal adenocarcinoma.

“It’s been a journey,” Dr Rachna told NBC News in a Zoom interview shortly before her death. “I’ve spent my entire life trying to eradicate cancer, primarily pancreatic cancer, but also liver cancers.”

Dr Rachna Shroff’s Scientific Work

Dr Rachna was a clinician-scientist and internationally respected expert in cholangiocarcinoma, a rare cancer of the bile ducts. She authored more than 80 publications and participated in more than 130 professional engagements.

In September, despite her own life-limiting diagnosis, one of her final wishes was to establish the Conquer Cancer – Rachna Shroff, MD, MS, FASCO Endowed Young Investigator Award in Biliary Cancers. Within weeks, she achieved her goal of raising more than $1.35 million to support future cancer research and innovation.

The daughter of a nephrologist mother and a biochemist father, Dr Rachna developed an early interest in cancer research in Tucson. As a high school student, she won the 1993 Osler Fellowship, which gave her the opportunity to work in the laboratory of Margaret Briehl, a University of Arizona Cancer Center member and professor at the College of Medicine – Tucson.

She completed her undergraduate studies at Brown University and earned her medical degree from Thomas Jefferson University. In 2010, she completed her fellowship at the University of Texas MD Anderson Cancer Center, where she subsequently served as an associate professor of gastrointestinal medical oncology from 2010 to 2018.

She returned to Tucson in 2018 after being recruited to the University of Arizona.

Dr Rachna became internationally recognized for her work in cholangiocarcinoma, focusing on a rare and historically difficult-to-treat disease at a time when treatment options were limited and no therapies had been approved by the US Food and Drug Administration specifically for the disease. The field has since advanced significantly, in part through landmark clinical trials she led as a principal investigator.

In a video recorded for a conference five years ago, Dr Rachna discussed how gastrointestinal cancer research was beginning to catch up with advances in better-known cancers.

“I will admit that we had a little bit of envy of the targeted therapy space in, say, lung cancer and breast cancer...but I think in the last decade or so, we have seen a dramatic improvement in terms of understanding the relevant targets for all of the different GI malignancies,” she told the 2021 Gastrointestinal Cancers Symposium.

Shroff was also renowned for her work developing novel therapies for pancreatic and hepatobiliary cancers.

Dr Rachna Shroff’s Family

Beyond her professional accomplishments, Dr Rachna's most cherished roles were those of wife, mother and friend.

She is survived by her husband, Dr Puneet Shroff, a professor of medicine and associate director of the Banner Medical Group’s Allergy Clinic; their children, Simran and Sachin.

The US Food and Drug Administration (FDA) is considering easing restrictions on certain peptides, potentially allowing specialty pharmacies to produce injections not approved for medical use, raising safety concerns.

The Department of Health and Human Services (HHS) has submitted an interim access policy for peptides to the White House for review, according to a government website posting on Thursday. The proposal was sent to the Office of Management and Budget, the Associated Press reported.

The list of peptides includes BPC-157, an unapproved peptide promoted online for pain relief, healing and performance enhancement, has gained popularity among wellness influencers and followers of Health Secretary Robert F. Kennedy Jr.'s Make America Healthy Again (MAHA) movement. A recent study found that its use increased 33-fold between 2020 and 2026.

What Is The FDA Planning?

The proposal could allow compounding pharmacies to produce certain peptides, including BPC-157, according to AP, citing two people familiar with the matter

The policy would reportedly give pharmacies greater assurance that they would not face enforcement action for producing these substances.

Formally permitting peptides for compounding would require federal rulemaking, a process that could take years. It remains unclear whether the administration intends to pursue that route.

In July, an FDA advisory committee recommended allowing six of seven peptides under review to be used by compounding pharmacies for patients with prescriptions. The recommendation went against FDA staff concerns that there was insufficient evidence to establish their safety and effectiveness.

The proposal has drawn support from some peptide sellers. Telehealth companies Hims & Hers and Noom have also announced plans to offer peptides if federal restrictions are eased. Wall Street analysts estimate the market could be worth $2 billion to $3 billion.

What Are Peptides?

Peptides are short chains of amino acids that play various roles in the body, including regulating hormones and processes involved in growth, metabolism and healing. Some peptide-based medicines are approved for conditions such as diabetes and obesity.

However, other peptides promoted online have not been adequately studied or approved as medicines.

BPC-157 is often combined with TB-500, a peptide derived from thymosin beta-4, in a combination marketed as the “Wolverine stack.” It is promoted online for tissue repair and recovery from muscle, tendon and other injuries. BPC-157 is not approved by the FDA for medical use.

What Are The Safety Concerns?

The FDA has raised concerns about limited human safety data, potential immune reactions and impurities in BPC-157 products. It has also cited risks associated with certain compounded peptides, including contamination, allergic reactions and tumor growth.

The agency's adverse-event database includes reports of injection-site reactions, shortness of breath and skin or gum pigmentation changes among people who used BPC-157. However, these reports do not establish that the peptide caused the events.

Compounded medicines can meet specific patient needs, but they are not FDA-approved. The agency does not verify their safety, effectiveness and quality through the same premarket approval process used for approved drugs.

Allowing pharmacies to compound certain peptides would not mean the substances had received FDA approval or that their safety and effectiveness had been established.
