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.

Scottish swimmer Archie Goodburn has made an emotional appeal for greater investment in brain cancer research in the UK, urging the government to "give us a chance to fight for our lives." His plea prompted a response from UK Prime Minister Andy Burnham, who invited the 25-year-old to a personal meeting.

Goodburn, who was diagnosed with inoperable brain tumors two years ago, broke down in tears during an interview on BBC Breakfast as he highlighted the struggles faced by people living with brain cancer and their families.

"Give Us a Chance to Fight"

"Andy Burnham, if you believe and want to make a change and a difference to the future of our country and our young population, please listen to us," Goodburn said, addressing the Prime Minister directly.

He urged the government to establish a national brain cancer lead, saying patients are enduring "unbelievable and unjust" experiences.

"There are clinical trials around the world, in the US, Australia and China, that could change lives. We are not seeing them in the UK, and it is unfair and unjust," he said.

Goodburn also appealed for greater investment in research.

"Please invest and make the difference. I'm on my knees begging—not just for my own life—but for those of my best friends, those affected, and families around the country. This has to change. The suffering is unbearable."

Prime Minister Invites Goodburn to Meet

Responding to the video on TikTok, Burnham thanked Goodburn for speaking out despite his own illness, and invited him to meet.

"Archie, thank you for this. I know how hard it must have been.

"What you're doing for other people while you're going through all this yourself shows the best of us. I'd really like to meet you and hear from you directly, and I've asked my team to get in touch."

Calls for Stronger Brain Cancer Research

Since being diagnosed just over two years ago, Goodburn has become a vocal advocate for improving brain cancer research and treatment.

"One of my dreams is that we see a future where brain cancer isn't the biggest killer of patients under 40," Goodburn said during the Commonwealth Games in Glasgow, where he competed and achieved his goal of reaching the 50m breaststroke final, but narrowly missed out on a medal.

Goodburn also criticized the Rare Cancers Bill, introduced by Scott Arthur MP and enacted earlier this year, saying it does not go far enough to improve outcomes for brain cancer patients.

The legislation covers 14 rare cancers and aims to encourage research and investment into treatments. However, Goodburn argued that brain cancer, while classified as rare by diagnosis numbers, is disproportionately deadly.

"Brain cancer is one of these in terms of incidents of diagnosis, but it's not the same in terms of the number of deaths it causes. Yes, it's rare, but it's extremely deadly. This frustrates me immensely."

He further noted that the new clinical lead and research lead positions created under the law are part-time roles covering all 14 rare cancers, amounting to just 36 working days per year.

"I do not see how 36 days a year is going to make that change for 14 different types of cancers, let alone the most deadly type of cancer."

Brain Tumours in Young Adults

Speaking to HealthandMe, Dr. Rakesh Patil, Consultant Medical Oncologist at AIMS Hospital, explained that brain tumours develop when abnormal cells grow uncontrollably within the brain or surrounding tissues. These tumours may be benign (non-cancerous) or malignant (cancerous).

While brain tumours are not among the most common cancers in young adults, they do occur. The exact cause remains unknown in most cases, though certain factors may increase risk, including:

• Genetic conditions
• Family history of brain tumours
• Previous exposure to radiation therapy
• Rare inherited disorders

Dr. Patil noted that many patients have no identifiable risk factors, making early diagnosis and timely treatment critical for improving outcomes.

A UK coroner's court is currently examining whether a popular weight loss medication is linked to the death of a 73-year-old woman. She developed severe abdominal pain shortly after increasing her dose of Mounjaro (tirzepatide).

The incident has highlighted the importance of recognizing warning signs that go beyond the drug's common side effects and seeking immediate medical help.

What Happened?

Caroline Savage, a resident of Wortwell in Norfolk, had been using Mounjaro through a private prescription for around four months to manage obesity.

According to evidence presented during the inquest, she had recently been advised to increase her dose from 7.5 mg to 10 mg after losing about 14 kg.

On October 18, 2024, Savage developed sudden, severe abdominal pain and was taken to Norfolk and Norwich University Hospital.

Doctors evaluated her for pancreatitis, a known but uncommon complication of GLP-1 weight loss medications, and ruled out an abdominal aortic aneurysm before discharging her with pain relief.

Hours later, she collapsed at home and died despite emergency efforts. A post-mortem found the cause of death to be faecal peritonitis, a life-threatening infection caused by a perforation in the intestine.

No Proof Of Direct Cause

Medical experts told the inquest that there is currently no established evidence linking Mounjaro directly to faecal peritonitis.

However, they discussed the possibility that in people with an underlying bowel condition, like diverticular disease, the medication's gastrointestinal effects could theoretically increase pressure within the intestine and contribute to a perforation.

Savage, although, had not been diagnosed with diverticular disease.

The coroner has not reached a final conclusion, and the inquest has been adjourned pending a narrative verdict later this month.

Family's Concerns Over Hospital Assessment

Representing the family, barrister Jasmine Leng argued that Savage's symptoms may have been attributed to expected side effects of Mounjaro rather than prompting further investigations.

She also questioned whether repeated pain assessments conducted after morphine administration may have underestimated the severity of her condition.

Lawyers representing the NHS trust acknowledged that documentation "wasn't as good as it could have been" but maintained that clinicians followed appropriate assessment methods and denied medical negligence.

Mounjaro Side Effects

Mounjaro belongs to the GLP-1 receptor agonist class of medicines, which slows stomach emptying and helps reduce appetite. As a result, nausea, vomiting, constipation, diarrhoea and abdominal discomfort are among some of its most common side effects.

However, experts say persistent, severe or worsening abdominal pain, especially when accompanied with vomiting, fever, bloating or an inability to pass stools, should never be dismissed as common side effects.

Such symptoms can indicate serious complications, including pancreatitis, bowel obstruction or, in rare cases, intestinal perforation, all of which require urgent medical attention.

The case comes after another UK death drew focus on the safety of GLP-1 weight loss drugs.

In 2024, Scottish nurse Susan McGowan's death certificate showed prescribed tirzepatide as a contributing factor alongside pancreatitis, septic shock and multiple organ failure.

Regulators have maintained that the overall benefits of these medicines outweigh their risks when used as prescribed.

Chipotle has gotten rid of jalapeño peppers from some of its restaurants after health officials identified them as a possible source of a Salmonella outbreak that has sickened at least 110 people, mostly in Minnesota.

The investigation is ongoing, and authorities say the contaminated ingredient may also have reached other Mexican-style restaurants.

About The Salmonella Outbreak

The Salmonella outbreak is being investigated by the Minnesota Department of Health, the U.S. Food and Drug Administration (FDA), and the Centers for Disease Control and Prevention (CDC).

At least 75 of the 84 people interviewed reported that they ate at Chipotle between June 14 and July 14. This has prompted health officials to look into all the ingredients served in those meals.

In response, Chipotle said it used its ingredient traceability system to identify a common lot of jalapeños that may be linked to the illnesses. It also said that it has replaced those peppers with stocks from different vendors.

"We immediately activated our traceability systems, identified the common lot of jalapeños and removed them from our restaurants," the company said, adding that it is cooperating with public health authorities in order to contain the outbreak.

Carlota Medus, senior epidemiologist supervisor at the Minnesota Department of Health, said investigators believe the contaminated peppers may have been supplied to more than one restaurant chain.

"It's not just Chipotle," Medus said, noting that other Mexican-style restaurants could also have received the same batch of peppers. She added that additional cases are expected because it can take weeks for infections to be diagnosed and reported.

What Is Salmonella?

Most healthy people recover within a week, but young children, older adults and those with weak immune systems face a higher risk of severe illness who often end up requiring hospitalization.

Not The First Time Jalapeños Have Come Under Scrutiny

Fresh produce like peppers can get contaminated anywhere along the supply chain, including during growing, harvesting, processing or distribution.

As jalapeños are eaten raw in foods like salsa, burrito bowls and tacos, any contamination may survive and end up infecting people.

This is not the first time jalapeño peppers have been linked to a major Salmonella outbreak.

In 2008, U.S. investigators traced an outbreak in multiple states that involved more than 1,400 illnesses linked primarily to contaminated jalapeño and serrano peppers imported from Mexico.

Chipotle's Previous Health Controversies

The latest investigation comes more than a decade after Chipotle faced a series of high-profile food safety incidents involving E. coli, norovirus and Salmonella between 2015 and 2018.

Those outbreaks prompted the restaurant chain to overhaul its food safety protocols, strengthen ingredient traceability and establish stricter food handling practices.

Officials stress that the current investigation is still underway, and no final determination has been made linking the outbreak exclusively to jalapeños.

The FDA is currently conducting an investigation to determine where the suspected peppers originated and whether they were distributed to other restaurants or states.
