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.

Remember Raghu Ram from the MTV reality show 'Roadies'? The actor and television host recently celebrated 10 years of a smoke-free life and took to Instagram to share his progress with fans. Smoking is injurious to health, and that is a known fact. It is associated with heart disease, cancer, hypertension, and even respiratory difficulties in the future. This habit can turn fatal too if one becomes addicted to nicotine. But for Raghu Ram, this journey ended 10 years ago, and he has never looked back since.

From chain smoker to now

"Iss mahine cigarette chhodkar mujhe pure 10 saal ho gaye hain. Or main aisa waise smoker nhi tha. Main peeta tha din mein 1-2 packets daily. Yani 20-40 cigarettes roz. Par maine bahut koshish ki chhodne ki, lekin addiction hoti hai, chor nhin pate hain log. Main bhi nhin chor paya tha," Raghu said in an Instagram video.

"Aisa chora ki wapas ek bhi kash nahin mara. 10 saal ho gaye hain mereko," he added.

How did Raghu Ram quit smoking?

On his podcast Mencyclopedia in 2023, Raghu Ram revealed that he once smoked 20–40 cigarettes a day for 15 years and then suddenly stopped.

"I smoked 20–40 cigarettes every day for 15 years, and then I just stopped. Cold turkey. And I had not taken a puff of a cigarette in 7 years," he said in his podcast titled How I Won the Longest Battle with My Addiction.

After trying several times to quit, Raghu Ram finally gave up smoking after marrying his wife, Natalie Di Luccio, a Canadian singer, in 2018.

Raghu Ram's 7-step guide to quitting smoking

Here is a simple seven-step guide from the former 'Roadies' host and judge:

1. Decide on a date when you want to quit smoking and announce it to everyone.
2. Overdo it a day or two before that so that you are fully disgusted by the act.
3. List all your smoking triggers in order of severity.
4. Avoid situations that can trigger you during the initial phase when you are struggling with withdrawal symptoms.
5. Once you are through the first two weeks, you can gradually put yourself in trigger situations—from least to most severe—and still manage to resist the urge to smoke.
Exercise regularly, as it makes a significant difference to your cravings.

For every person who has ever quit smoking or wanted to do it

For everyone who has ever quit smoking, the reasons may look different, but they all have two things in common: first, an addiction they are battling; and second, withdrawal symptoms to overcome. You may not be able to follow Raghu Ram's seven-step guide exactly, but his story is inspiring enough to encourage people to try quitting smoking.

X-Men actor Tyler Mane has revealed that he has been diagnosed with a "super-rare" form of breast cancer.

In a post on Instagram, Mane, a former professional wrestler, shared that he has been diagnosed with the condition, which is predominantly associated with women. He noted that only about 1 per cent of breast cancer cases occur in men.

The 59-year-old actor said he initially considered keeping his diagnosis private, but ultimately decided to speak publicly about it because men are often diagnosed at more advanced stages of the disease due to a lack of awareness.

“I have some bad news: I start chemo today. One in 750 men will be diagnosed with breast cancer in their lifetime and I’m one of them,” he said in a video posted on Instagram.

Mane revealed that doctors initially dismissed the lump he discovered.

“My doctors initially dismissed it and it was only because my wife pushed me to get the lump removed that I got in early,” he said.

The actor admitted that his first instinct was to keep the diagnosis secret.

“I’ll be honest, my first reaction was to keep it secret. I mean it’s kind of embarrassing,” he said.

However, after learning more about male breast cancer and the importance of early detection, he decided to share his experience publicly to help raise awareness.

While Mane did not reveal the stage of his cancer, he informed of undergoing chemotherapy and urged his followers to spread awareness about the disease.

“I’m gonna kick cancer’s ass. Thank you for coming along for the journey. We need to spread the awareness. Cancer sucks but if you catch it quick enough, you can win this battle,” he wrote.

Breast Cancer in Men

According to the CDC, about one in every 100 breast cancer cases diagnosed in the United States occurs in men. The situation is similar globally, with the World Health Organization estimating that between 0.5 and 1 per cent of breast cancers occur in men.

The lifetime risk of breast cancer in men is currently less than one in 1,000. However, the incidence of the disease is increasing, particularly with advancing age.

The average age at diagnosis for men is about 67 years, roughly five years later than the average age of diagnosis in women.

Because breast cancer is often not suspected in men, the condition can be overlooked or misdiagnosed, resulting in many cases being detected at later stages.

What Are the Risk Factors in Men?

Several factors can increase a man's likelihood of developing breast cancer. These include:

• Advancing age
• Genetics
• Family history
• Lifestyle and hormonal factors, including excess weight, alcohol consumption, liver disease and hormonal imbalances
• Medical conditions such as gynecomastia and Klinefelter syndrome
• Radiation exposure, particularly previous radiation treatment to the chest area

Symptoms to Watch For

The symptoms of breast cancer in men are similar to those in women, but men may overlook them because they are less aware of the disease.

Common signs include:

• A lump in the breast, usually painless
• Nipple discharge
• Dimpling, redness or inversion of the skin or nipple

Why Early Detection Matters

Routine mammography is not generally recommended for men because of the low prevalence of the disease. However, men considered to be at high risk, including those with a strong family history or genetic predisposition, may benefit from periodic screening and should discuss appropriate options with their healthcare providers.

An indigenous low-cost point-of-care (PoC) testing approach has shown promise in making screening for Human Papillomavirus (HPV) more affordable and accessible, potentially improving the early detection of cervical cancer, according to a joint study led by researchers from AIIMS, ICMR, and the WHO's International Agency for Research on Cancer (IARC).

The study, published in the International Journal of Cancer, found that PoC tests have the potential to become scalable, low-cost screening tools in India and other low- and middle-income countries (LMICs).

The objective of the study was to evaluate indigenous HPV DNA testing platforms for use in primary cervical cancer screening.

Four Indigenous Tests Evaluated

While several Indian HPV tests have been developed, many had not yet been validated against the international standards laid down by the WHO.

The study evaluated four point-of-care tests developed by 3 Indian companies:

• Genes2Me – HPV-Q
• Mylabs India – PathoDetect HPV-7 and PathoDetect HPV-14
• Molbio Diagnostics – Truenat HR-HPV-Plus

Each test was developed by repurposing existing COVID-19 RT-PCR platforms. HPV-Q and PathoDetect HPV-14 can detect all 14 high-risk HPV types, while PathoDetect HPV-7 detects seven high-risk types: 16, 18, 31, 33, 45, 52, and 58.

To assess performance, researchers analyzed 1,159 cervical samples collected from studies conducted in Argentina and Costa Rica.

The results showed:

• Truenat HR-HPV-Plus: Sensitivity 80.4%, specificity 91.5% — met IARC validation criteria.
• PathoDetect HPV-7: Sensitivity 68.1%, specificity 89.0% — lower sensitivity.
• HPV-Q and PathoDetect HPV-14: Did not meet validation criteria.

Indigenous Platforms Can Be Game-Changers

"This study demonstrates that indigenous platforms can achieve clinical validation, quality standards, and accuracy comparable to global gold-standard tests. It will be a game-changer for cervical cancer prevention and early detection in India," said lead author Dr Neerja Bhatla, Professor Emeritus, NCI and former Head of the Department of Obstetrics & Gynecology at AIIMS New Delhi.

Dr Shalini Singh, Director of ICMR-NICPR, added that HPV DNA testing at age 35 and again at age 45 is central to WHO's cervical cancer elimination strategy, but high costs remain a major barrier in LMICs.

"Affordable indigenous solutions are essential to expand screening coverage and reduce disease burden," she said.

Cervical cancer continues to be a major public health challenge in India, with around 127,000 new cases and 80,000 deaths reported annually.

Globally, cervical cancer is the fourth most common cancer in women. According to WHO data for 2022, there were approximately 662,000 new cases and 348,000 deaths worldwide.

Regular screening of women over 30 years of age every 3-5 years can help detect precancerous and cancerous lesions early. However, screening coverage in India has remained low despite the inclusion of visual inspection with acetic acid (VIA) in the national screening program for breast, oral, and cervical cancers.

Persistent infection with carcinogenic HPV types is the necessary cause of cervical cancer. WHO recommends a transition to HPV testing as the preferred strategy for cervical cancer elimination.

Using validated HPV tests, only two rounds of screening — at ages 35 and 45 — may be sufficient to help achieve elimination targets. However, most existing HPV tests are expensive, require sophisticated laboratory infrastructure, and are not easily available at last-mile health facilities.

The researchers said that the point-of-care HPV testing approach, thus, could be a major breakthrough, enabling affordable diagnostics and even same-day treatment for women who test positive.

Potential for Nationwide Rollout

The researchers noted that while the recently introduced national HPV vaccination campaign will benefit younger generations, there remains an urgent need to expand HPV testing for women over 30 who are currently at risk of cervical cancer.

Dr Showket Hussain of the ICMR-National Institute of Cancer Prevention and Research (NICPR), Noida, said the validated platform has strong potential for integration into national screening programs because district-level healthcare personnel are already familiar with similar testing systems.

"Future advancements such as self-sampling and high-throughput adaptations could further enhance accessibility," he said.

The findings are expected to support India's cervical cancer elimination goals while offering a scalable model for other low-resource settings globally.
