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 2026 target trial emulation has found that glucagon-like peptide, also known as GLP-1, which is used by type-2 diabetes patients, can raise the risk of suffering from erectile dysfunction. According to a report published in the European Medical Journal, the impact of GLP-1s on sexual health outcomes in diabetic men has been inconsistent and limited. Erectile dysfunction, however, has been a prominent complication affecting 50 per cent of men with type-2 diabetes over their lifetime.

The effect of GLP-1 on men with type-2 diabetes

For this, researchers analysed the electronic health records of men aged 18 years and above with type-2 diabetes in the US from January 2019 to September 2024. Participants were started on treatment with either dipeptidyl peptidase-4 inhibitors (DPP4i) or GLP-1, with 5,524 and 4,910 individuals, respectively. Men with a history of erectile dysfunction diagnosis or end-stage renal disease were not part of the study population. The mean age of these men was 63 years, and the average BMI was 32.8—55 per cent of participants were White, and 23 per cent were Black. GLP-1 users were younger and had a higher prevalence of obesity compared to DPP4i users.

Higher rate of erectile dysfunction

Experts involved in the study found that the incidence of erectile dysfunction in the GLP-1 group was about 35 cases per 1,000 person-years. In the case of DPP4i users, the number dropped to 28 per 1,000 person-years. Hence, people in the GLP-1 cohort had a 26 per cent higher risk of developing erectile dysfunction over a three-year follow-up period. Results were consistent across subgroups; however, they lacked statistical significance after adjustment for negative outcomes.

Can GLP-1 cause erectile dysfunction?

Researchers noted that the findings of the target trial emulation suggest that sexual health outcomes must be considered in diabetic men, especially those dealing with type-2 diabetes and undergoing treatment with GLP-1 drugs. These findings also highlight the need for randomised trials with standardised erectile dysfunction assessments to further investigate biological pathways.

What complications does type-2 diabetes cause in men?

Type-2 diabetes can cause the following complications in men:

1. Heart disease
2. Stroke
3. Erectile dysfunction
4. Kidney disease
5. Retrograde ejaculation
6. Lower testosterone levels
7. Urinary retention or frequent urination
8. Vision loss—diabetic retinopathy

New global guidelines have just been released for breast cancer screening, and they involve the introduction of artificial intelligence in the process. Breast cancer is one of the most commonly diagnosed forms of tumour in women globally. In India, it is the most common form of cancer detected in women living in metro cities. According to the National Comprehensive Cancer Network (NCCN), a non-profit alliance of 33 cancer treatment centres in the US, women aged 35 years and above should be eligible for AI-powered mammogram risk assessment rather than at a later stage.

Why is timely prediction of cancer risk important?

The NCCN aims to boost the diagnosis rates of breast cancer by paving the way for accurate predictions of risks. This will, over time, help achieve timely screening. As per experts, this change in global breast cancer screening guidelines, especially the integration of AI in the process, marks a paradigm shift—from a detection-first to a prediction-first approach. Historically, mammograms were used after the age of 40 for the detection of existing cancers. The modern guidelines, however, recommend that women get screened from the age of 35 onwards, with AI algorithms used to predict future risks.

What this means for India

Experts say that this shift is important for India. In India, breast cancer is the most prevalent form of tumour among women, and delayed diagnosis is one of the reasons responsible for the current mortality rate. Breast cancer is also often diagnosed late because of the unavailability and limited accessibility of screening facilities. Introducing AI in this process can help bridge the gap in several ways.

Doctors say that the introduction of AI in the breast cancer screening process will help facilitate the identification of high-risk patients, regardless of their family history or the presence of genetic markers. This is important because most cases of breast cancer do not arise from these factors. This helps provide screening in a way that does not require universal testing.

Traditional screening methods for breast cancer

Traditionally, cancer screening largely depends on family history and age. AI, however, can now analyse large volumes of imaging data, clinical history, breast density, and genetic factors for a more personalised approach and targeted diagnostic methods. The adoption of AI-driven risk assessment can help improve patient outcomes, as per doctors.

Use of AI in breast cancer detection

Women at high risk of breast cancer can make detection easier for themselves by making use of advanced modalities such as MRI. An MIT-developed AI-based breast cancer risk model can detect tumours up to five years in advance using mammographic data alone. This AI-based risk assessment technique has also been recommended by global experts and is published in The Lancet. The study found consistent favourable outcomes.

Rising global temperatures are driving heatwave conditions in India, said the Indian government, while releasing an advisory to warn people about the increased health risks.

Taking to the social media platform X, the Ministry of Health and Family Welfare urged the public to take precautions during extreme heat.

"Heat waves are increasing due to rising global temperatures," said the Ministry in the advisory.

It shared safety measures and an informative poster explaining the impact of rising temperatures and steps to manage heat stroke.

The poster highlighted that a rise of 1 degree Celsius in global temperatures can lead to longer durations of heatwaves.

Further, it stated that insufficient hydration during heatwaves reduces the body's natural ability to cool itself, which can result in heat stroke.

The poster also detailed preventive measures to avoid heat stroke. It also advised people to avoid heavy work during mid-noon hours, drink plenty of water, avoid consuming heavily caffeinated or sugary drinks as they may cause dehydration, wear light-colored clothes, and take frequent breaks while working outdoors.

Which States Are At Risk?

The India Meteorological Department (IMD) has warned of heatwave conditions in several parts of the country.

Regions likely to face extreme heatwave conditions until April 20 include Telangana and Rayalaseema, Madhya Maharashtra and Marathwada, North Interior Karnataka, Madhya Pradesh, Chhattisgarh, Vidarbha, Odisha, Jharkhand, and West Rajasthan.

In addition, hot and humid weather conditions are expected in coastal regions such as Kerala, Tamil Nadu, Gujarat, and Coastal Andhra Pradesh.

Meanwhile, the national capital saw its hottest day of the year on Wednesday, as temperatures climbed sharply, signaling the onset of harsher summer conditions. According to IMD, the maximum temperature at Safdarjung, the city’s base station, touched 39.2 degrees Celsius, about 3 degrees above normal. This surpassed Tuesday’s 38.2 degrees Celsius, marking a noticeable upward trend.

While the mercury is expected to inch closer to 42 degrees Celsius by Friday, the weather office has ruled out heatwave conditions for at least the next week.

“A gradual rise is expected in maximum temperatures by 2-3 degrees during the next three days and fall by 1-2 degrees thereafter. The maximum temperatures are likely to be above normal to appreciably above normal during the next seven days," Times Of India quoted a Met official as saying.

As per the weather department, despite a slight chance of light rain in parts of Haryana and NCR on April 17 and 18, there is no relief expected for Delhi.

Forecasts suggest daytime temperatures will hover between 39 degrees Celsius and 41 degrees Celsius on Thursday, rising further to 40-42 degrees Celsius from Friday through Sunday.

The IMD has cautioned that such above-normal temperatures could pose moderate health risks, especially for infants, elderly individuals, and those with chronic illnesses.

Hydration Is key, Say Doctors

Dr. Anil Gomber, Director and Senior Consultant – Internal Medicine & Diabetologist, Yatharth Hospital, told HealthandMe: “It is crucial to take preventive measures to avoid heat-related illnesses".

Prolonged exposure to high temperatures can lead to dehydration, heat exhaustion, and heatstroke, which can be fatal if untreated.

Heat also places extra strain on the heart and lungs, increasing the risk of heart attacks and respiratory distress.

Heatwaves can increase the risk of deaths among the elderly and those with underlying medical conditions. It can also affect healthy and young people. Exposure to intense heat can cause headaches, dizziness, cramps, and fainting, particularly for those working outdoors or engaging in strenuous activity.

"Elderly people, kids, and those with chronic conditions like heart disease or diabetes face higher risks, so check on neighbors and family daily," Dr. Meenakshi Jain Principal Director & HOD Internal Medicine, Max Super Speciality Hospital, told HealthandMe.

She urged people to "watch for warning signs like dizziness, rapid heartbeat, nausea, or confusion, and move to a cool area immediately if they appear—seek medical help for severe symptoms. Keep homes cooler by closing curtains during the day and opening windows at night".
