Birthdays are exciting for everyone. There's celebration, a cake, and balloons. But what if it goes wrong? This is what happened with Giang Pham, from Vietnam, who was celebrating her 33rd birthday on February 14, when a hydrogen balloon in her hand touched the flame from the candle on the cake and exploded on her face.

This incident was also captured on camera. The footage clearly shows how the balloon blew up as soon as it touched the flame. Her friends were shocked and can be heard gasping in the background as they saw this.

In the days following the incident, she also shared photos on her Instagram showing her bandaged face, and revealed the first-degree burns on her hand and second-degree burns on her face. However, the good news was that her vision was unaffected, though for her face to recover, it would take months.

She is now also warning others about the risks of using highly inflammable hydrogen balloons. The other alternative could be a helium balloon, which you could fly higher and they remain on the ceiling.

Health Update

She revealed that her doctor estimated up to six months for her skin to recover. She would still have to go to the hospital for dressing and treatment. Another such case happened with a woman named Tine from Australia, when on her son's 7th birthday, the balloon exploded and "shook her house". Her son was burned in the forearm.

Such incidents happen because decorators want to save the cost by replacing helium with hydrogen, which is highly inflammable.

In Healing

Giang shared that she experienced second-degree burn on her face and first-degree burn on her hands. As per John Hopkins Medicine, first degree burns affect only the epidermis, or the outer layer of skin. The burn site becomes red, painful, dry, however, there are no blisters. A mild sunburn could be an example of such a burn. This is also called superficial burns.

Whereas, second degree burns involve the epidermis and part of the dermis layer of the skin. The burn site appears red, blistered and could also be swollen and painful. This is also known as partial thickness burn.

Then comes the third degree burns, also known as full thickness burn. This destroys the epidermis and dermis and could also damage the underlying bones, muscles, and tendons. However, when the bones and muscles are burned, it could be referred to as a fourth degree burn. The burn sit appears white or charred and there is no feeling in the area since the nerve endings are destroyed.

How burns are treated?

The right way to treat a burn depends on its depth and how much of the body it covers. While minor, superficial burns can be managed at home, deeper or larger burns may need medical attention. Keep these essential guidelines in mind:

Do:

• Remove the source of the burn immediately – For example, take off clothing soaked in hot liquid to prevent further damage.
• Run cool water over the burn – This helps soothe the skin, except in cases of certain chemical burns.
• Keep the burn clean and protected – Cover it with a clean, non-stick bandage when possible.
• Seek medical help – If the burn is deeper than a superficial layer, larger than your hand, or full-thickness, see a doctor.

Don’t:

• Use home remedies like bleach or butter – These can make the burn worse.
• Apply ointments or creams on deep burns – They can trap heat and worsen the injury.
• Put ice on the burn – It can cause more damage to the skin.
• Pop blisters – This increases the risk of infection.

Knowing these simple steps can make a big difference in burn care and healing.

Climate change is already driving illness, disrupting essential services and putting health at risk, WHO Director-General Dr Tedros Adhanom Ghebreyesus warned at COP31 in Türkiye on Monday. Calling the climate crisis a health crisis, he urged governments to strengthen health systems, implement existing climate plans and increase funding for proven interventions.

Speaking at a news briefing alongside Turkish Health Minister Kemal Memişoğlu, Tedros said the health impacts of climate change were no longer a distant threat.

"They are here and now," he said, pointing to heat, floods, droughts, wildfires and air pollution that are increasingly affecting healthcare services.

"Health is also the most compelling reason for climate action," he said.

Tedros outlined three priorities to address the health impacts of climate change, saying the newly launched Antalya Initiative for Health Resilience (AIR) could help countries put them into practice.

1. Build climate-resilient health systems

Hospitals and clinics must be able to operate through heatwaves, floods and storms. This requires reliable electricity and water, early warning systems, resilient supply chains and trained healthcare workers.

2. Move from plans to implementation

Countries already know many of the measures that work, but financing, capacity and coordination remain major barriers to implementing them at scale, Tedros said.

He stressed that climate-related health risks cannot be addressed by health ministries alone. Ministries overseeing finance, environment, energy, transport, housing and urban planning must work together and integrate health into national adaptation plans and climate commitments.

3. Increase funding for proven interventions

Tedros called for greater investment in measures that can save lives, reduce emissions and strengthen economies.

"Climate action is not simply a cost. It's an investment in healthier people, more resilient communities and stronger economies," he said.

A WHO technical analysis published on November 4 found that six priority climate-health actions could save 1.6 million lives annually and generate US$24 in benefits for every dollar invested.

Launched by the COP31 Presidency, the Antalya Initiative for Health Resilience (AIR) is a voluntary, non-binding initiative to help countries share practical experience and strengthen health systems against climate-related risks.

It will support the documentation of successful interventions, peer learning and the exchange of approaches that countries can adapt to their own settings.

AIR complements the WHO-led Alliance for Transformative Action on Climate and Health (ATACH), which brings countries and partners together to make, renew and report climate-health commitments. While

ATACH provides a platform for coordination, AIR focuses on sharing practical lessons from implementation.

The initiative will also build on the Belém Health Action Plan (BHAP), adopted at COP30, with lessons and resources carried forward through ATACH at future COPs.

"The focus now should be implementation, implementation and implementation," Tedros said, urging countries to learn from existing best practices rather than reinvent solutions. He called on governments to strengthen climate resilience across health systems and urged climate negotiators and funders to make health an explicit part of climate decisions and financing.

COP31 Health Day: What To Expect

Health Day, which opens COP31 on November 9, focuses on building dynamic and resilient health systems. It features four high-level panel discussions and a ministerial roundtable covering climate-resilient healthcare, digital health, climate-sensitive health technologies, humanitarian assistance and climate-health financing.

The scale of the health threat underscores the urgency. Around 3.5 billion people live in contexts highly vulnerable to climate change.

More than 90% of deaths from climate-related disasters over the past two decades occurred in developing countries. Air pollution, including pollution from fossil fuel combustion, causes around seven million deaths globally each year, according to WHO.

Two experimental heart drugs developed by Novartis and Novo Nordisk have failed to reduce major cardiovascular events in separate late-stage trials, despite successfully targeting cholesterol and inflammation.

Novartis' pelacarsen lowered lipoprotein(a), or Lp(a), by 78%, while Novo Nordisk's ziltivekimab substantially reduced inflammatory markers. However, neither drug reduced heart attacks, strokes or cardiovascular deaths compared with a placebo.

"Everybody in the world, me included, thought that this was going to work," said Dr. Steven Nissen of Cleveland Clinic, presenting the pelacarsen results at the American Heart Association's Scientific Sessions 2026.

Novartis' Pelacarsen Fails To Reduce Heart Events

The seven-year Phase III Lp(a) HORIZON trial involved 8,323 people with established cardiovascular disease and elevated Lp(a) levels across 42 countries.

Participants received monthly injections of pelacarsen or a placebo. Despite reducing Lp(a) by 78%, the drug did not lower the risk of non-fatal heart attacks, strokes, urgent procedures to unblock arteries or cardiovascular deaths.

Even participants with higher Lp(a) levels showed no cardiovascular benefit.

"I cannot avoid the disappointing conclusion – it didn’t work," Nissen said, adding that cardiovascular outcomes remained unchanged despite the significant reduction in Lp(a).

Novo Nordisk's Ziltivekimab Also Fails

Novo Nordisk's Phase III ZEUS trial tested whether ziltivekimab, an experimental anti-inflammatory drug, could reduce cardiovascular events by blocking interleukin-6 (IL-6).

The trial included 6,376 patients with atherosclerotic cardiovascular disease, chronic kidney disease and systemic inflammation.

In July 2026, Novo announced that the trial had failed to demonstrate a cardiovascular benefit. Results published in the New England Journal of Medicine on November 7 showed that although the drug substantially reduced inflammatory markers, it did not prevent major cardiovascular events.

During a median follow-up of 33 months, cardiovascular death, non-fatal heart attack or non-fatal stroke occurred in 17.6% of patients receiving ziltivekimab and 17.7% receiving placebo.

On September 7, Novo Nordisk discontinued two additional late-stage trials of ziltivekimab in patients with heart failure and inflammation.

An independent data monitoring committee recommended stopping the studies, concluding they were unlikely to succeed.

Why Did The Drugs Fail?

Nissen suggested that participants may have had advanced cardiovascular disease, making it too late for the drug to prevent further events.

Dr. Roger Blumenthal of Johns Hopkins suggested that participants' blood pressure and LDL cholesterol were already well controlled, leaving limited scope for additional risk reduction.

Another hypothesis was that anti-clotting medications taken by all participants may have diluted pelacarsen's potential effect, since Lp(a) is thought to contribute to cardiovascular disease partly by promoting blood clots.

These remain hypotheses, not proven explanations.

The findings also do not mean that Lp(a) or inflammation is irrelevant to heart disease. They show that lowering these markers with these particular drugs did not reduce cardiovascular events in the populations studied.

What Happens Next?

People with elevated Lp(a) can manage their cardiovascular risk by addressing other risk factors.

Nissen recommended exercise, weight management and lowering LDL cholesterol with statins when appropriate.

Three other cardiovascular outcome trials involving investigational Lp(a)-lowering drugs are underway. Their results may help determine whether targeting this cholesterol particle can prevent heart attacks and strokes.

Climate change is no longer a distant environmental concern. The effects of increasing temperatures, extreme weather events, melting glaciers, changing rainfall patterns and worsening air pollution on human health are alarming. Countries are continually identifying these health risks but monitoring if their climate policies are actually effective is the big question. This is one of the important areas of discussion at the 31st United Nations Climate Change Conference (COP31), which starts on November 9, 2026 in Antalya, Türkiye.

The World Health Organization (WHO) is stressing upon health to become a central part of climate policy discussions. The health body has urged countries to increase focus on measurable action, healthcare systems that can withstand climate change and funding to execute those actions.

Ahead of the conference, Dr Diarmid Campbell Lendrum, Head of the Climate Change, Energy, and Air Quality Unit at WHO headquarters said, “Health is the strongest argument for climate action."

Countries Need Reliable Health Indicators For Climate Change

Climate change has numerous effects on health. Extreme heat can lead to dehydration, heat exhaustion and heatstroke, while floods and droughts can disrupt access to safe drinking water, food and healthcare. Changing temperatures and rainfall patterns can also fuel spread of infectious diseases, including mosquito-borne illnesses.

Air pollution, which is closely linked to the burning of fossil fuels, adds to the burden of respiratory and cardiovascular disease.

However, measuring these effects is not as straightforward as one might think.

An increase in hospital admissions during a heatwave, for instance, could be considered an indicator, but countries also need to monitor who is most affected, whether healthcare facilities can cope and whether preventive measures are working.

A WHO review published in October 2025, Mapping Climate Change and Health Indicators, examined 31 reports from 22 countries. It identified 3,880 indicators being used to assess health risks related to climate change. After removing overlaps and combining similar measures, researchers identified 1,684 unique indicators.

These indicators covered climate hazards, population exposure, vulnerability, health outcomes, the impact on healthcare systems, future risks, and the policies and resources available to address them.

What Will Countries Measure?

Health indicators can help governments think beyond recording extreme weather events and examine their consequences for public health and healthcare systems. Some of the areas that countries could monitor include:

• Heat-related illness and deaths: Hospital admissions, emergency visits and mortality linked to extreme temperatures.
• Infectious diseases: Changes in the geographical spread of climate-related diseases, including dengue and malaria.
• Food and water security: Malnutrition, food insecurity and illnesses linked with unsafe drinking water.
• Healthcare infrastructure: The number of hospitals vulnerable to floods, heatwaves and other extreme weather events.
• Healthcare preparedness: Availability of early warning systems, emergency response plans, trained health workers and essential emergency medicines.
• Population vulnerability: Health impacts on children, older adults, people with disabilities, outdoor workers and underprivileged communities.

What Is WHO Calling For At COP31?

WHO is using COP31 to push for stronger implementation of existing climate and health commitments. Its priorities include making healthcare systems resilient to climate change, reducing the health sector's environmental footprint and ensuring that health considerations are included in climate policies and financing decisions.

The conference will begin with a dedicated Health Day on November 9, featuring discussions on health technologies related to climate, digital health, humanitarian response and resilient healthcare systems.

WHO's November 2026 briefing estimates that 3.3 to 3.6 billion people live in contexts highly vulnerable to climate change. It also says that scaling up six climate health actions could save 1.6 million lives annually and generate around US$24 in returns for every dollar invested.

Ultimately the challenge for countries is to turn climate and health commitments into measurable improvements. Tracking heat-related deaths, diseases, healthcare preparedness and unequal health impacts can help governments understand where action is working and where gaps remain.
