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.

Prostate cancer is the most common cancer among men in the UK. The country records around 55,000 new prostate cancer cases and nearly 12,000 deaths every year.

Although the UK recently ruled out universal prostate cancer screening, opting instead for targeted screening of high-risk men, new cases continue to emerge every day. The latest high-profile figures diagnosed with the disease are former Liverpool winger John Barnes and comedian Bobby Davro.

John Barnes Calls Prostate Cancer A ‘Taboo Subject’

Barnes revealed that he had his prostate removed following a cancer diagnosis and described the condition as a "taboo subject" for men.

"Not many people know and it’s a bit of a taboo subject because we support women with breast cancer and it’s not even an issue," he told Times Radio.

Barnes stressed that "a lot of men don’t want to admit it or want to have it done because it makes them feel less than a man."

He added: "Men have to bite the bullet and swallow their pride and admit if they have problems."

Bobby Davro Reveals Symptom Before Diagnosis

Meanwhile, 67-year-old Bobby Davro spoke on This Morning about his diagnosis, revealing that he had experienced erectile dysfunction beforehand.

Speaking on the ITV show, Davro said: "I think one in eight men get it. I think a lot of men of color, they get more prostate cancer, so it’s got to be checked.

"So go along and have your PSA (Prostate-Specific Antigen) checked, have the old prostate examined."

Davro continued: "He [the doctor] said: 'It’s a bit swollen, I think you should go and have a PSA test.' And it was 24, which wasn’t good at all."

"Not really. The only thing I had was erectile dysfunction. It wasn’t nice. I tried taking the blue pills. I realised something wasn’t quite right," he said about symptom before diagnosis.

Many other high-profile figures have been diagnosed with prostate cancer, including former UK Prime Minister David Cameron, BBC radio host Bob Harris, and six-time Olympic gold medalist Chris Hoy.

Despite the high burden of disease, the UK currently has no national prostate cancer screening program because of concerns over the accuracy of PSA tests. However, there has been growing pressure in recent years to introduce routine screening.

What Do The New Guidelines Say?

After reviewing the latest evidence, the National Screening Committee (NSC) recommended against broad population-wide screening for prostate cancer.

The committee said the harms of screening outweigh the benefits for most groups. The final guidance states that routine screening should not be offered to:

• All men
• Black men, despite their risk being nearly double that of the general population
• Men with a family history of prostate cancer, as the disease is common enough that family history alone does not sufficiently narrow risk

Who Is Eligible For Targeted Screening?

Instead, the NSC recommends:

• Targeted prostate cancer screening involving PSA testing every two years for men aged 45 to 61
• Screening only for men who carry a pathogenic BRCA2 gene variant
• Screening for those who also have a family history of breast, ovarian, pancreatic, or prostate cancer

Symptoms To Watch For

The prostate is a small walnut-shaped gland in men that produces seminal fluid, which nourishes and transports sperm. Prostate cancer develops when abnormal cells begin growing in the gland.

Common symptoms include:

• Blood in the urine or semen
• Difficulty urinating
• Erectile dysfunction
• Reduced force in the urine stream
• Bone pain
• Unexplained weight loss.

Alkem Laboratories today announced the launch of semaglutide in single-shot pre-filled syringes in multiple dose strengths, with prices starting at Rs 350.

The company, in a statement, said it is the first in India to introduce semaglutide in a single-shot pre-filled syringe format for the management of Type 2 diabetes mellitus and obesity as an adjunct to diet and exercise.

The ready-to-use format will expand treatment options for patients while lowering entry barriers through affordable pricing.

“Semaglutide has the potential to change how we manage metabolic disorders. With the launch of our pre-filled syringes, we are widening the choice available to doctors and patients, alongside the pen options we have already introduced,” said Dr. Vikas Gupta, Chief Executive Officer of Alkem Laboratories.

“In India, where we are seeing a continuous rise in disease burden, offering multiple, practical drug delivery formats is an important step in helping more patients start and stay on the therapy,” he added.

Alkem noted that it has received approval from the Drugs Controller General of India (DCGI) to manufacture and market semaglutide pre-filled syringes.

The launch follows Alkem’s introduction of semaglutide in pre-filled disposable and reusable injection pen formats in the Indian market in March 2026. The company has also secured regulatory approval for semaglutide vials, which it plans to launch soon.

Meanwhile, domestic peers such as Torrent Pharma and Dr Reddy’s have also introduced non-infringing tablets, with Lupin, Sun Pharma and several others expected to follow suit.

Semaglutide: Risks Vs Benefits

In people with type 2 diabetes, Harvard Health noted that the body's cells are resistant to the effects of insulin and the body does not produce enough insulin, or both. This is when GLP-1 agonists stimulate the pancreas to release insulin and suppress the release of another hormone called glucagon.

These drugs also act in the brain to reduce hunger and act on the stomach to delay emptying, so you feel full for a longer time. These effects can lead to weight loss, which can be an important part of managing diabetes.

Notably, semaglutide is not just a glucose-lowering drug, it improves weight and has proven cardiovascular, liver, and renal benefits.

Wider availability could therefore help reduce long-term complications such as heart disease and kidney failure. If used appropriately, this could indeed be a major step forward in total metabolic care, the experts said.

“The increasing affordability of GLP-1 receptor agonists is a double-edged development. On one hand, it significantly improves access for patients with obesity, type 2 diabetes, and high cardiovascular risk, conditions that are highly prevalent in India. These drugs have demonstrated meaningful benefits in weight reduction, glycemic control, and even cardiovascular risk reduction, which could translate into long-term public health gains,” Dr Vivek Bindal, Senior Director & Head, Bariatric and Robotic Surgery, at Max Healthcare, told HealthandMe.

Western Australia is seeing a steady rise in mpox infections, with seven cases reported during the past week, according to the Department of Health.

In a statement, the department said that 22 mpox cases have been reported in Western Australia so far in 2026. The figure marks a significant increase compared with 2025, when 27 cases were recorded throughout the entire year, and 2024, which saw 23 cases.

Health Authorities Urge Vigilance

Health officials have advised the public to remain alert for symptoms of the disease. Public health investigations and contact tracing are also underway to prevent further transmission.

Nineteen of the cases were acquired locally, while three were linked to overseas travel. Two of the cases reported this year were in cisgender women, a first for Western Australia. Another two cases were reported in heterosexual men, the officials said.

Dr. Paul Armstrong, Director of Communicable Disease Control, said the department was working closely with affected individuals and their contacts to help prevent further spread of the virus.

“Mpox is a viral infection that typically causes mild illness, including fever, headache, muscle aches, swollen lymph nodes, or fatigue, followed by a skin rash or lesions,” Dr Armstrong said.

“It does not spread easily between people and is mainly transmitted through very close or intimate contact with an infected person.

“While anyone can contract mpox, recent cases in Australia and internationally have occurred more commonly among sexually active gay, bisexual, and other men who have sex with men,” the expert said.

Vaccination Recommended For High-Risk Groups

Dr Armstrong encouraged eligible people in Western Australia to consider vaccination, particularly before travelling to countries experiencing mpox transmission.

“The mpox vaccine is available through sexual health clinics and participating GPs for people at higher risk of exposure,” he said.

“Two doses are recommended for optimal protection, and vaccination can reduce the risk of infection and severe disease.”

Anyone concerned they may have been exposed to mpox, or experiencing symptoms consistent with the infection, should call ahead before attending a healthcare facility so appropriate precautions can be arranged.

What Is Mpox?

Mpox is a viral disease caused by the monkeypox virus, which belongs to the same family of viruses as smallpox.

The virus spreads through close physical contact with an infected person, contaminated materials, or infected animals.

The illness generally lasts between two and four weeks and resolves on its own. However, severe disease can occur, particularly in children, pregnant women, and people with weakened immune systems.

Complications may include secondary infections, respiratory problems, and, in rare cases, death.

Vaccination: Vaccines originally developed for smallpox can help protect against mpox. Health authorities recommend vaccination for people at higher risk of exposure.

Good Hygiene: Regular handwashing, avoiding close contact with infected individuals and contaminated materials, and following public health guidance can reduce the risk of infection.

Early Detection And Monitoring: People who develop symptoms or believe they may have been exposed should seek medical advice promptly. Laboratory testing, including RT-PCR, is available to confirm infection and support timely treatment and contact tracing.
