For over 15 years, Dr Anthony Shum, a pulmonologist at the University of California, San Francisco has been studying a rare genetic disorder called the COPA Syndrome. It stands for coatomer subunit alpha and is a rare, inherited disorder that affects the lungs, joint, and kidney. The National Organization for Rare Disorder also notes that it is a genetic autoimmune disorder that is caused by mutations in the COPA gene. This disease affects families unpredictably—some individuals with the mutation develop severe lung damage early in life, while others remain completely healthy. Now, Shum’s team has discovered a protective genetic variant that may offer new hope for treatment.

A Breakthrough

Researchers found that some relatives of COPA Syndrome patients stayed healthy despite carrying the same COPA gene mutation that causes the disease. The key difference? These unaffected individuals had a protective version of another gene called HAQ-STING.

When scientists introduced HAQ-STING into diseased lung cells from COPA patients, the cells returned to a balanced state, suggesting that this gene could be used as a therapy.

“We really think HAQ-STING could be a gene therapy tool and a step toward a cure,” said Shum, whose findings were published in the Journal of Experimental Medicine.

Families Who Solved The Mystery

Shum’s journey into COPA Syndrome research began in 2011 when he treated a young woman, Letasha, who had severe lung bleeding. Her mother, Betty Towe, mentioned that Letasha’s sister, Kristina, had suffered from similar symptoms. Over the years, Betty had taken both daughters on a four-hour trip to UCSF for treatment. After tracing their family history, Shum discovered that their distant relatives in Texas and Oakland also had lung problems and arthritis. In 2015, Shum, along with scientists from Baylor College of Medicine and Texas Children’s Hospital identified the COPA gene mutation. They realized that it was the common factor behind the illness. However, only some of the 30 individuals with the mutation actually developed symptoms, leaving a major question unanswered.

The Domino Effect

It was established that it occurs when a mutated COPA gene causes another gene STING to go overdrive. The STING that helps fight infections in COPA patients, remain permanently active, which leads to chronic inflammation that damages the lungs, kidneys, and joints. In 2020, while studying STING’s role in the disease, researchers discovered a key variation: HAQ-STING. This version of STING, present in about one-third of the population, appeared to neutralize the harmful effects of the COPA mutation.

To confirm their theory, the scientists needed both affected and unaffected family members to participate in the testing. Letasha, Kristina and Betty immediately volunteered. The researchers then analyzed DNA samples from 26 COPA patients and their healthy relatives. They also conducted CT scans and blood tests to ensure that unaffected members did not have any hidden symptoms. When the findings were all clear, it was revealed that all the healthy individuals had HAQ-STING, while none of the COPA patients did. This was the first known case of a common gene variant completely protecting against a severe genetic disease.

Encouraged by this discovery, researchers tested HAQ-STING’s effects in a lab setting. They introduced it into diseased lung cells from COPA patients, and the cells returned to normal function.

Way Ahead

Shum believes HAQ-STING could lead to game-changing treatments, including:

  • Prenatal gene therapy for babies diagnosed with COPA Syndrome before birth
  • Aerosol delivery of HAQ-STING for adults, directly targeting the lungs

Before publishing their findings, Shum called Betty with the news—her own HAQ-STING gene had protected her from the disease. He also informed Letasha and Kristina, who were overwhelmed with relief and joy.

“We always believed Dr. Shum would get to the bottom of it,” said Letasha. “This discovery is going to change lives.”

Breastfeeding is important not only for babies' health and nutrition but also for protecting mothers from serious diseases, the World Health Organization (WHO) said.

It urged governments to strengthen access to services and interventions that support breastfeeding as part of World Breastfeeding Week, observed annually from August 1–7.

The 2026 theme, "Breastfeeding for a Sustainable Start in Life: Strengthen What Works," focuses on tracking progress, evaluating impact, and scaling proven approaches that improve breastfeeding outcomes.

Breastfeeding Could Save Hundreds of Thousands of Lives

"Scaling up breastfeeding could prevent almost 400,000 child deaths and around 140,000 maternal deaths each year," said UNICEF Executive Director Catherine Russell and WHO Director-General Dr. Tedros Adhanom Ghebreyesus in a joint statement.

"Every US$1 invested in breastfeeding promotion generates an estimated US$59 in economic returns through lower health-care costs, improved cognitive development, higher educational attainment, and increased lifetime earnings," they added.

Health Benefits for Babies and Mothers

The experts noted that breastfeeding is one of the simplest and most powerful ways to protect a child's health. It provides infants and young children with essential nutrition, boosts immunity, helps protect against serious illnesses, and supports cognitive development.

For mothers, breastfeeding also offers significant health benefits by reducing the risk of noncommunicable diseases such as breast and ovarian cancers, and type 2 diabetes.

Global Breastfeeding Rates Have Improved

The WHO said breastfeeding rates have improved globally due to sustained investments in policies and programs supporting mothers and families.

Exclusive breastfeeding during the first six months increased from around 37 per cent in 2012 to more than 47 per cent today. Over the past five years, the prevalence of breastfeeding up to two years of age has risen from 38 per cent to 50 per cent.

Progress Remains Uneven

Despite these gains, the WHO said many countries continue to lag behind global targets.

"Coverage of services supporting breastfeeding remains low, policies are inconsistently enforced, and service quality is often inadequate, especially in low-income, fragile, and humanitarian settings," the WHO said.

The agency noted that cost-effective interventions include skilled breastfeeding support within health systems, community-based counselling, maternity protection policies, and protection from the exploitative marketing of commercial milk formulas.

WHO, UNICEF Call for Stronger Support

WHO and UNICEF called on governments, health systems, workplaces, communities, civil society organizations, and families to strengthen the "Warm Chain of Support" for breastfeeding.

During World Breastfeeding Week, the agencies urged countries to:

  • Strengthen health systems to provide quality breastfeeding support for mothers and newborns.
  • Expand community-based counselling and peer support programs.
  • Fully implement and enforce the International Code of Marketing of Breast-milk Substitutes.
  • Invest in paid maternity leave and supportive workplace policies.
  • Integrate breastfeeding interventions into antenatal, perinatal, and postnatal health-care services.
  • Sustain breastfeeding support in humanitarian and fragile settings.

"Breastfeeding is vital. By investing in proven solutions, we can give every child the best possible start in life and ensure every mother gets the care and services she needs," the agencies said.

What Is Driving India's High Burden Of Childhood Cancers?

Updated Jul 31, 2026 | 09:56 PM IST

SummaryIn most children, cancer develops because of genetic changes that occur during early development. These changes are usually not linked to lifestyle factors or inherited from parents.

A new study published in The Lancet Regional Health–Southeast Asia has found that India accounts for 68% of all childhood cancer cases in the SAARC region.

While the country's large child population contributes to the high numbers, experts say underdiagnosis and incomplete cancer registration may mean the actual burden is even greater.

An international team of researchers, including from the US, India, and Canada, estimated that nearly 37,700 children aged up to 14 years were diagnosed with cancer across South Asia in 2022, with 17,700 deaths reported. India alone accounted for an estimated 25,939 cases and 12,028 deaths.

The researchers noted that because cancer registration remains incomplete, particularly in rural areas, the true number of childhood cancer cases in India could exceed 50,000 annually.

India's Large Child Population Drives Numbers

India is home to more than 380 million children, accounting for nearly 69% of the child population in the SAARC region. This naturally contributes to the country's higher share of childhood cancer cases and deaths.

However, experts emphasize that population size is only part of the explanation. Delayed diagnosis, limited access to specialized treatment, and gaps in cancer registration continue to affect both disease estimates and patient outcomes.

Leukemia Most Common Cancer

Dr. Narendra Agrawal, a leading Hematologist and Bone Marrow Transplant Physician and Senior Consultant and Unit Head of Haemato-Oncology at Rajiv Gandhi Cancer Institute & Research Centre, told HealthandMe that childhood cancer remains a major public health concern in India.

"Current estimates suggest that around 70,000–80,000 children and adolescents develop cancer each year, although the exact number remains uncertain due to expanding cancer registration systems". The most common childhood cancers in India include:

  • Leukemia
  • Lymphomas
  • Brain tumors
  • Bone tumors

What Causes Childhood Cancer?

Unlike many adult cancers, most childhood cancers do not have a clearly identifiable or preventable cause. Dr. Agrawal explained that, in most children, cancer develops because of genetic changes that occur during early development. These changes are usually not linked to lifestyle factors or inherited from parents.

Recognized Risk Factors

Although the causes of most childhood cancers remain unclear, some well-established risk factors include:

  • Ionizing radiation: High-dose exposure before birth or during childhood increases the risk of leukemia and certain other cancers.
  • Genetic syndromes: Conditions such as Down syndrome, Li-Fraumeni syndrome, and neurofibromatosis increase susceptibility to specific childhood cancers.
  • Certain infections: Epstein–Barr virus (EBV) is associated with some lymphomas, HIV increases lymphoma risk, and chronic hepatitis B infection raises the risk of liver cancer.
  • Environmental and parental exposures: Tobacco smoke, certain chemicals, pesticides, and some occupational exposures have been investigated as possible risk factors, although evidence remains inconclusive.

Challenges Beyond Disease Burden

Dr. Agrawal said India's substantial childhood cancer burden is largely driven by its population size. However, improving outcomes requires addressing several systemic challenges.

Key issues include:

  • Delayed diagnosis
  • Limited access to specialized pediatric oncology services in some regions
  • Treatment abandonment
  • Incomplete cancer registration
According to the expert, overcoming these barriers is essential to ensuring earlier diagnosis, better treatment access, and more accurate estimates of childhood cancer across the country.

Why Monsoon Weather Triggers Acne: Expert Treatments That Actually Work

Updated Aug 1, 2026 | 03:00 PM IST

SummaryMonsoon humidity and sweat can worsen acne, but expert-recommended skincare, topical treatments, and dermatologist-guided therapies can effectively control breakouts and prevent future flare-ups.

The arrival of the monsoon often brings sudden skin problems. The face feels greasy within hours, fresh breakouts appear overnight, and products that worked perfectly a month ago seem to do very little.

This can be very frustrating, especially when you have been following your routine religiously, but the issue is not with your skincare regimen. It is the constant humidity, sweat, and moisture buildup which make you prone to breakouts and give your skin an oily look.

Why Does Acne Get Worse During the Monsoon?

Many people assume the solution is washing the face repeatedly, but over-cleansing can strip away the skin's protective barrier, which in return produce even more oil, ultimately creating a cycle that makes breakouts harder to control.

Instead of changing your entire routine, it often helps to switch to lightweight, non-comedogenic products that suit the season while keeping the skin barrier healthy.

What Triggers Acne During the Monsoon?

It is often the little things we don't pay much attention to that end up making monsoon acne worse. Sweat sitting on the skin for hours, makeup or sunscreen that isn't removed properly at the end of the day, or even constant touching of the face, can all make it easier for pores to become clogged.

When this happens alongside high humidity, the chances of developing acne naturally increase. Another common mistake is skipping moisturiser because the skin already feels oily. In reality, if the skin is dehydrated, it will get irritated easily and secrete more sebum, making acne harder to manage.

Expert Treatments That Actually Work

When seasonal breakouts become frequent or start leaving marks behind, professional treatments can help manage both active acne and its after-effects.

Harmony XL Pro for Recurring Acne and Redness

For many people, monsoon brings inflamed acne, redness and repeated flare-ups that don't always improve with skincare alone. In such cases, dermatologist-led treatments like Harmony XL Pro can make a big difference.

The procedure utilises targeted laser energy that penetrates deeply into the skin, which not only addresses the acne-causing bacteria but also calms inflammation and improves skin texture from within.

Hydration-Focused Treatments for Dull Monsoon Skin

Oily skin isn't the only concern during the monsoon. Many people also notice that their skin looks dull and feels dehydrated despite the humidity.

While hyaluronic acid serums, lightweight moisturisers and barrier-repair creams can help to some extent, they may not provide the deeper hydration some people need.

When the skin needs a deeper boost, skin boosters can help improve hydration from within, leaving the surface looking healthier and more refreshed.

Facial Peels for Clogged Pores and Post-Acne Marks

If the skin feels congested during the rainy season, facial peels can be another helpful option. They gently exfoliate the surface, clear clogged pores and gradually improve post-acne marks.

They are especially useful when humidity makes the skin look dull and uneven, since they help refresh the skin while also supporting better texture over time.

Wrapping Up

Every season brings specific challenges for your skin, and the monsoon is no different. While a standard skincare routine can manage mild breakouts, persistent acne, redness, or frequent flare-ups often require professional attention.

Understanding when your skin needs expert care is crucial to skin health, as it prevents long-term marks and helps maintain healthier skin throughout the season.
