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.

A simple blood test that measures androgen hormone levels could help diagnose endometriosis with more than 95 per cent accuracy, according to new research.

The University of Edinburgh-led findings offer hope for a faster, less invasive way to detect the condition, which affects an estimated 10 per cent of women of reproductive age worldwide—around 190 million people—and often takes years to diagnose.

The researchers found that women with endometriosis have a distinct androgen hormone profile in their blood, suggesting the condition could one day be identified through a simple blood test rather than invasive procedures.

The research team analyzed blood samples from 159 women with confirmed endometriosis and 57 women without the condition. Their investigation focused on androgen hormones, including a lesser-studied group known as 11-oxygenated androgens, which are produced by the adrenal glands.

The researchers discovered that women with endometriosis consistently had higher levels of 11-ketotestosterone, one of the 11-oxygenated androgens.

Using this distinct hormone profile, the team was able to differentiate women with and without endometriosis, correctly identifying more than 95 per cent of those with the condition.

If validated in larger clinical studies, the test could reduce reliance on invasive diagnostic procedures such as laparoscopy and help women receive treatment much earlier.

The findings also provide new insights into the role of androgens in the development of endometriosis and may help guide future treatment strategies.

Why Androgens Matter

Endometriosis occurs when tissue similar to the lining of the uterus grows outside the womb. These cells respond to hormones, leading to inflammation, chronic pelvic pain and the formation of scar tissue.

While the disease is known to be influenced by the female hormones estrogen and progesterone, the role of androgens—often referred to as male hormones, though they are naturally present in women as well—has received comparatively little attention.

The researchers believe the newly identified androgen signature could improve understanding of how the disease develops and progresses.

Why Earlier Diagnosis Is Important

Diagnosing endometriosis remains a major challenge. Current methods include ultrasound, MRI scans and laparoscopy—a surgical procedure in which a camera is inserted through a small incision in the abdomen to confirm the presence of endometrial-like tissue.

Because symptoms often overlap with those of other conditions, many women wait years before receiving a diagnosis. Earlier diagnosis could help reduce prolonged pain, limit disease progression and allow patients to begin treatment sooner, said the researchers, while stressing the need for larger studies.

What Is Endometriosis?

According to the World Health Organization (WHO), endometriosis is a chronic condition in which tissue similar to the lining of the uterus grows outside the uterus. It most commonly affects the ovaries, fallopian tubes and the tissue lining the pelvis.

The condition can begin with a person's first menstrual period and continue until menopause. Common symptoms include severe pelvic pain, painful periods, pain during intercourse, bowel or urinary symptoms during menstruation, and difficulty conceiving.

The recent rise in COVID-19 cases and deaths in Andhra Pradesh has renewed concerns over the virus, prompting neighbouring states such as Tamil Nadu and Odisha to step up surveillance. Andhra Pradesh has reported three COVID-related deaths along with several active cases.

However, health experts say the current situation does not indicate a major public health threat and have urged people to focus on prevention rather than panic.

Tamil Nadu's Health Department has also clarified that there is no evidence of a highly virulent COVID-19 variant circulating in the state. Officials noted that current COVID-19 infections remain lower than in previous years.

"The SARS-CoV-2 virus never truly disappears; it continues to resurface through new mutations. Viral strains naturally mutate as part of their evolution, making viral illnesses highly dynamic," Dr Abha Mashur, Pulmonologist at Lilavati Hospital and Research Centre, Mumbai, told HealthandMe.

She said the key concern is not the emergence of new variants, but the severity of disease they cause.

"At present, we are predominantly seeing upper respiratory involvement and milder cases of viral illness," said Dr Mashur, adding that Lilavati Hospital has admitted only one or two COVID-19 patients recently, all of whom required monitoring but experienced only mild illness.

Who Is At Higher Risk?

While most infections are mild, experts caution that certain groups remain vulnerable to severe disease. These include:

• Elderly individuals
• Pregnant women
• People with chronic heart disease
• Patients with COPD or interstitial lung disease (ILD)
• Those with chronic kidney or liver disease
• Immunocompromised individuals.

Omicron Subvariants Circulating In India

According to Dr Mashur, the current wave is being driven by Omicron subvariants — the JN.1 variant and the BA.3.2 variant — that remain highly transmissible but are not causing severe illness in most people.

JN.1: The expert explained that the JN.1 variant is highly transmissible and possesses enhanced immune-evasion capabilities, allowing it to partially bypass immunity from previous infection or vaccination. However, she said it continues to cause predominantly mild illness compared to earlier variants.

BA.3.2: The BA.3.2 variant has accumulated a large number of mutations, raising concerns about immune escape. Despite this, available evidence suggests it has not led to more severe disease and is not currently considered a cause for alarm.

No Need for Panic

The experts stressed that the current rise in cases should encourage vigilance rather than fear. Vaccination, masking in high-risk settings, and early medical consultation remain the most effective tools to reduce transmission and protect vulnerable populations.

"The current situation should not create panic, but should prompt people to seek medical attention early. Those who develop symptoms of a viral infection should avoid public spaces and consult a doctor promptly so that transmission can be curtailed at the earliest," Dr Mashur said.

Dr Neha Rastogi, Senior Consultant, Infectious Diseases, Fortis Memorial Research Institute, Gurugram, urged people to continue following basic preventive measures.

"To reduce the risk of infection, people should stay up to date with COVID-19 vaccinations, wear masks in crowded indoor settings, maintain hand hygiene, ensure good ventilation, and avoid close contact when unwell. Anyone experiencing symptoms such as fever, cough, or breathlessness should get tested and seek timely medical advice."

The debate around the effects of late-night eating on metabolism and overall fitness is not new. A new study has found a strong link between night owls’ time of eating and their metabolic health.

The study observes that those who stayed late at night tend to have poor metabolic health and effectively more body fat than those who didn’t, as they tend to have the lion’s share of their calories in the later part of the day.

How Was The Study Conducted?

The study examines an important area of nutrition called chrononutrition, which basically refers to how the time of eating affects the body’s circadian rhythm. It investigated how chronotype is associated with dietary intake, meal timing, body composition, and metabolic health.

Published in Frontiers in Nutrition, the study observed 287 healthy women aged 18 to 45 from New Zealand. Their food intake was studied for five days along with their meal timings.

Participants were classified as morning, intermediate, or evening chronotypes using a validated questionnaire. They also recorded everything they ate and drank over five days.

Researchers studied body composition using dual-energy X-ray absorptiometry (DXA), a highly accurate method for measuring body fat, and analyzed metabolic markers including glucose, insulin, cholesterol, and triglycerides.

What Did The Study Find?

The study found that women with an evening chronotype had higher body mass index (BMI), a higher percentage of body fat, and more abdominal fat compared with morning and intermediate chronotypes.

Interestingly, these differences were observed even though total daily calorie intake did not significantly differ between the groups.

The study also found that rather than eating more food overall, evening chronotypes tended to delay their meals and consumed a larger proportion of their daily calories later in the day.

The findings indicate that when people eat may play an important role in metabolic health along with what and how much they eat.

The researchers wrote, “Our findings indicate that women with a later chronotype tend to have higher body fat and consume a greater proportion of their energy intake later in the day.”

Why Meal Timings Affect Your Metabolism?

Although the current study directly does not determine whether late eating directly causes higher body fat, it observes a pattern that chronotype and meal timing are important factors to consider in order to achieve a better fitness level.

The body's internal clock is responsible for regulating many metabolic processes, including blood sugar control, insulin sensitivity, and digestion, among others. Late night eating not only interferes with insulin sensitivity but also impairs your metabolic health.

Research has repeatedly shown that these processes function a lot more efficiently earlier in the day. Eating a large proportion of daily calories late in the evening is therefore less favorable for metabolism as it can lead to increased fat accumulation over time.

With time, those with evening chronotype are at a greater risk of obesity and obesity-related chronic lifestyle disorders like hypertension, diabetes, high cholesterol, heart disease, and more.
