Low-dose CT chest scans could help detect pneumonia in at-risk patients while exposing them to only small amounts of radiation, a new study has found. The research, published in Radiology: Cardiothoracic Imaging, shows that ultra-low-dose scans can effectively detect pneumonia in patients with compromised immune systems, enabling doctors to treat the infection before it becomes life-threatening. According to the researchers, these scans expose patients to just 2% of the radiation dose used in a standard CT scan.

"This study paves the way for safer, AI-driven imaging that reduces radiation exposure while preserving diagnostic accuracy,” lead researcher Dr Maximiliano Klug, a radiologist with the Sheba Medical Center in Ramat Gan, Israel, said in a news release. He added that CT scans are the gold standard for detecting pneumonia but there are concerns regarding the risk posed by repeated exposure to radiation. There is a solution- ultra-low-dose CT scan. However, the problem is that these scans can be grainy and hard to read, researchers said.

Study Gives Solution To This

To overcome that, Klug's team developed an AI program that could help "de-noise" low-dose scans, making them sharper and easier to read. Between September 2020 and December 2022, 54 patients with compromised immune systems who had fevers underwent a pair of chest CT scans -- a normal dose scan and an ultra-low-dose scan. The AI program cleaned up the low-dose scan, and then both sets of images were given to a pair of radiologists for assessment. Radiologists had 100% accuracy in detecting pneumonia and other lung problems with the AI-cleaned low-dose scans, but 91% to 98% accuracy in examining the scans that hadn’t been improved through AI, results show.

"This pilot study identified infection with a fraction of the radiation dose," Klug said. "This approach could drive larger studies and ultimately reshape clinical guidelines, making denoised ultra-low dose CT the new standard for young immunocompromised patients.

How Can You Detect Pneumonia?

Pneumonia is a lung infection that causes the air sacs in the lungs to fill with fluid or pus and can be caused by bacteria, viruses, or fungi. The symptoms can range from milk to severe, which includes:

Coughing with or without cough

Fever

Chills

Trouble breathing

Chest pain, especially when breathing deeply or coughing

Sweating or chills

Rapid heart rate

Loss of appetite

Bluish skin, lips, and nails

Confusion.

How to detect Pneumonia in coughing newborns and toddlers?

Pneumonia can severely affect newborns and young children as their lungs are comparatively more sensitive. As per Dr Goyal, young children can cough for various reasons including seasonal infections and tonsillitis, which is very common in this age group. But if they look visibly irritable and have poor sleep patterns, then parents must reach out to an expert. "I am not saying that parents must visit a hospital but any local paediatrician would be able to detect pneumonia in your kid.

The climate crisis is also a major health crisis, but six proven measures could help prevent 1.6 million deaths every year, according to the World Health Organization (WHO).

A new WHO report, released ahead of COP31, highlights six climate and health interventions that could save lives while delivering trillions of dollars in economic and fiscal benefits.

“The climate crisis is a health crisis, but much of the harm it causes can be prevented with tools we already have,” said Dr Tedros Adhanom Ghebreyesus, WHO Director-General.

“This report shows that scaling up proven, affordable actions could save millions of lives, with the greatest gains in the countries that need them most. As governments prepare for the next round of climate negotiations, protecting health must be at the centre of climate action,” he added.

The report estimates that scaling up the six actions globally could prevent 1.6 million deaths annually, equivalent to one in every 40 deaths, based on modelled projections.

The six measures include:

• Heat-health warning systems
• Climate-resilient drinking-water services
• Basic sanitation services
• Hygiene and handwashing facilities
• Cleaner household fuels and technologies for cooking and heating
• Efficient fossil fuel pricing policies

Together, these actions could also help avoid 16.7 billion tonnes of CO₂ emissions, equivalent to 31% of global annual greenhouse gas emissions, excluding land use, land-use change and forestry.

Heat-health warning systems were the most cost-beneficial intervention assessed, generating an estimated US$835 in benefits for every US$1 invested. However, estimates varied across different scenarios and sensitivity analyses, ranging from US$364 to US$1,272 for every US$1 invested, the WHO said

Meanwhile, efficient fossil fuel pricing policies were estimated to deliver the largest overall economic welfare benefits, at US$3,041.10 billion. Estimates across different scenarios and sensitivity analyses ranged from US$690.59 billion to US$5,342.64 billion.

These policies were also projected to generate US$5,440.93 billion in fiscal benefits, with estimates ranging from US$3,442.96 billion to US$5,440.93 billion, the WHO said. The policies are also estimated to prevent 1.2 million deaths annually.

COP31: Health To Be A Key Focus

The 2026 United Nations Climate Change Conference, commonly known as COP31, will take place in Antalya, Türkiye, from November 9 to 20. The conference's dedicated COP31 Health Day will be held on November 9, the first day of the conference.

Governments are expected to share their climate reports and discuss ways to advance climate-resilient and environmentally sustainable health systems.

Former British Olympic sprinter Beth Dobbin, diagnosed with myalgic encephalomyelitis (ME), spends more than 22 hours a day in bed because of the debilitating condition. She is urging UK Prime Minister Andy Burnham to meet her and commit to increased government funding for ME research.

Following Dobbin's October 21 appeal, 360 sportspeople have signed a letter backing her campaign. The group includes 114 Olympians and Paralympians, who have won a combined 77 medals.

In a post on X, Dobbin expressed surprise at the response, saying: “I can’t believe 360 people signed in just 1 week, so many amazing names and messages still coming in of people wanting to add theirs (so feel free to message to add yours, we’re keeping on the pressure!!!)”

The 32-year-old retired from athletics in April 2026, describing her illness as “serious” and “life-changing”, BBC Sport reported. She had reached the 200m semi-finals at the Tokyo Olympics in 2021 and won bronze in the 4x200m relay with Scotland at the 2022 Commonwealth Games in Birmingham.

Among the signatories are Everton manager David Moyes, United States women's national football team manager Emma Hayes, former Chelsea and England centre-back Millie Bright, athletes Laura Muir, Eilish McColgan and Adam Gemili, Olympic sprinter Dina Asher-Smith and diver Tom Daley.

The letter calls on Burnham to “level the playing field” for ME research funding compared with other illnesses and “give hope to the many affected that something is being done about this life-destroying, much-ignored illness and its spiralling impact”.

It highlights the disparity in government research funding between ME and other conditions.

“Between 2019 to 2024, UK government research funders committed just £6.6m in funding for research into ME, compared to £79.1m for Parkinson's and £496.4m for dementia,” the letter states.

It adds that biomedical research funding for ME was “almost non-existent” before this period and that the lack of investment has contributed to the absence of approved treatments.

How Did Beth Dobbin Develop ME?

Dobbin's health began deteriorating after back-to-back COVID-19 and glandular fever infections during the winter of 2021-22, she told BBC Sport.

She experienced worsening fatigue, slower running times and soreness in the glands in her neck and armpits. Initial tests by British Athletics doctors failed to identify the cause.

Despite her symptoms, she continued training in 2022. At the European Championships, she false-started after losing all feeling in her legs while in the starting blocks.

Her condition continued to worsen. She struggled to stand and spent most of her time in bed. After consulting four or five specialists, she was diagnosed with ME.

Dobbin has since been largely confined to her home and bed. Even conversations, bright lights and loud sounds can trigger a “crash” lasting days or, in severe cases, months. According to BBC Sport, she has left her house just five times this year, mainly for medical appointments and blood tests.

What Is Myalgic Encephalomyelitis (ME)?

ME, also known as chronic fatigue syndrome (CFS), is a complex, chronic illness that can cause severe fatigue, pain, sleep disturbances and problems with thinking and memory.

Symptoms do not improve with rest and can fluctuate in severity. While some people can continue working or studying, others experience severe disability and may require round-the-clock care or tube feeding.

There is no known cure or specific approved treatment for ME. More than 400,000 people in the UK are thought to have the condition, although the actual number could exceed one million.

A Department of Health and Social Care spokesperson previously told BBC Sport: “Myalgic encephalomyelitis (ME) can have a devastating impact on people's lives, and we are determined to accelerate progress in understanding and treating this debilitating condition.”

The 2026 US midterm elections have delivered significant victories for Democrats, including two healthcare professionals. Physician Amy Acton defeated Republican Vivek Ramaswamy in Ohio’s gubernatorial race, while paediatrician Annie Andrews won South Carolina’s Senate race against Republican Darline Graham.

Both victories have brought healthcare professionals into the political spotlight as medical costs, insurance affordability and access to treatment remain major concerns for American voters.

Acton, a former director of the Ohio Department of Health, became widely recognised for her leadership during the COVID-19 pandemic. Andrews drew on her experience as a paediatrician to campaign on healthcare access and affordability.

"It’s the honor of my lifetime to be named your Ohio Governor-Elect," Acton said, in an Instagram post.

"South Carolina, you have shown the nation — in an era of partisan divides, of vitriol and namecalling, in a politics dominated by billionaires, special interests, and insiders in Washington — that we will not bow down. We will not back down. And we will chart our own course," added Andrews on X.

Acton's victory marks a setback for Republicans in Ohio, where the governor's office was previously held by the party. She sought to return the governorship to Democrats after two decades, despite Ohio's increasingly Republican lean in recent elections.

The closely watched contest saw Ramaswamy, a biotech entrepreneur and former 2024 Republican presidential candidate, secure the Republican nomination with endorsements from President Donald Trump and the state Republican Party.

According to the Associated Press (AP), Acton received 50.8% of the vote, against Ramaswamy's 45.9%, with 86% of ballots counted.

In South Carolina, Andrews defeated Darline Graham, the sister of the late Republican Senator Lindsey Graham. She became the first Democrat to win a US Senate seat in the state in 28 years.

What Could These Wins Mean For Healthcare Policy?

The Democratic gains could create opportunities to challenge President Donald Trump's healthcare agenda through congressional oversight and legislative action.

Healthcare affordability was a major voter concern. A Kaiser Family Foundation (KFF) poll found that six in 10 registered voters worried about medical costs. Voters trusted Democrats more than Republicans on healthcare costs (42% versus 22%) and abortion policy (42% versus 27%).

Abortion-related measures also featured on ballots in Virginia, Nevada, Idaho and Missouri, where voters considered repealing existing abortion protections.
