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?

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.

In a major crackdown on social media use among those under the age of 16, the UK government, led by Prime Minister Keir Starmer, is preparing to curb children's access to harmful content online.

In recent weeks, the government has examined a variety of options for restrictions, including a blanket ban on under-16s accessing social media, similar to measures introduced in Australia and Karnataka in India.

Why Is the UK Considering a Social Media Ban?

The proposed plan comes amid growing concerns about mental health, online abuse, and child protection.

Several studies have linked excessive social media use to increased social isolation, sleep loss, higher stress levels, reduced physical activity, and less time spent outdoors, all of which can have significant health consequences.

In addition, concerns about children's online exploitation, cyberbullying, and exposure to inappropriate content have fueled calls for stricter regulations. Another key concern is the rise of online grooming, sextortion, and harmful content that can be accessed by children through social media and other digital services.

The government has been since months reviewing evidence on how social media affects young users and whether certain platform features encourage addictive behavior. Policymakers are also examining the role of algorithms that promote endless scrolling and prolonged engagement, The Sunday Guardian reported.

The UK government is yet to make the final decision and publish an official list of social media platforms that would be restricted if the proposed rules move forward. However, reports suggest that platforms considered to pose higher risks to children could face tighter age restrictions. This include:

• TikTok
• Instagram
• Snapchat
• X
• Facebook
• Discord
• Reddit

Beyond social media restrictions, the government is also looking at measures aimed at preventing children from creating, sharing, or viewing explicit images on smartphones and other devices.

Prime Minister Starmer has given major technology companies, including Apple and Google, a three-month deadline to introduce stronger safeguards designed to protect children from online exploitation and sextortion.

“When it comes to the safety of our children, standing by is not an option,” he said, while speaking at London Tech Week

The proposed system would require adults to undergo verification before sending, receiving, or accessing explicit content, while technology companies could face penalties if they fail to implement the required protections.

The move is designed to address the growing problem of children being pressured into sharing intimate images that are later used for blackmail or abuse.

Social Media Ban in Australia And India

Anyone under the age of 16 in Australia is now banned from using social media services. These platforms include TikTok, X, Facebook, Instagram, YouTube, Snapchat, and Threads. Under the law, people under 16 cannot create new social media accounts, and their existing accounts will be deactivated.

In India, Karnataka became the first state to announce plans for a broad restriction on social media use among teenagers. Andhra Pradesh and Bihar have also been considering similar measures aimed at restricting social media use among children.

Audrey Leishman, wife of professional golfer Marc Leishman, initially believed she was suffering from the flu after developing common flu-like symptoms. However, her condition rapidly worsened and was later diagnosed as sepsis, a life-threatening medical emergency.

The Virginia woman nearly lost her life, spending 10 days in the intensive care unit (ICU). Following the ordeal, she faced a long recovery and had to relearn how to walk, Fox News reported. Now recovered, Leishman is dedicated to raising awareness about the condition through her nonprofit organization, the Begin Again Foundation. She has also written a children's book aimed at helping families recognize the warning signs.

Symptoms Began After IUD Removal

Leishman faced the ordeal in 2015. She started experiencing symptoms of what she initially thought was an upset stomach a couple of days after having her intrauterine device (IUD) removed, according to the nonprofit Sepsis Alliance.

The next day, the mother of three said she began feeling unwell, experiencing stomach cramps and "severe pain in my right elbow and left big toe," along with a high fever, nosebleeds, diarrhea, and shortness of breath. "I could barely hold my 18-month-old son because I was so weak. My temperature was 102°F," Leishman said.

She eventually went to urgent care, where doctors initially thought she had some form of an autoimmune disease, Fox News reported. As the days went on, Leishman started to feel worse. Her fever spiked higher, and she developed severe stomach issues. "I actually thought I was going a little bit crazy … I hadn't injured myself. I was really confused as to what was going on," Leishman said.

"They took a very long time to figure out what was going wrong with me." "They kept testing me for different things," she continued. "Eventually, they admitted me, and I was in the ICU for a total of 10 days — five of which were in a medically induced coma." During this time, her temperature and heart rate were abnormally high, and her blood pressure was dangerously low.

Sepsis Led to Respiratory Failure

The sepsis ultimately developed into acute respiratory distress syndrome. "I very much remember not being able to breathe," Leishman recalled. "That was by far the scariest part. It got to the point where I had to pause between every word to take a breath, and it was basically like sipping air."

Leishman was eventually diagnosed with sepsis and toxic shock syndrome (TSS), according to Sepsis Alliance.

While she did recover, she was unable to walk, and the first year of recovery was "very difficult." "When I finally did wake up, it was quite the process of relearning how to walk again, dealing with at-home physical therapy and being on a PICC line (peripherally inserted central catheter)," Leishman said.

"My immune system was so compromised that I was sick constantly," she added, noting that although she is now healthy, her memory "is not what it used to be" and that she gets fatigued more often. The original cause of her sepsis remains unclear, she said, but it may have been linked to her recent IUD removal.

Warning Signs of Sepsis

Sepsis is a life-threatening reaction to an infection that harms the immune system, tissues, and organs. It can lead to organ failure or death if not treated urgently, according to the Cleveland Clinic.

According to Sepsis Alliance, the acronym TIME can help people recognize potential warning signs of sepsis and seek urgent medical care.

T — Temperature: Body temperature is unusually high or low.

I — Infection: Signs or symptoms of an infection are present.

M — Mental Decline: Confusion, excessive sleepiness, or difficulty waking up.

E — Extremely Ill: Severe pain, extreme discomfort, or shortness of breath.

Health authorities of the United Kingdom have confirmed that there is a confirmed case of meningitis at the University of Surrey, where a student has been infected with it. Meningitis is one of the most dangerous diseases and containing it comes first for the health authorities.

The UK Health Security Agency (UKHSA) is working to provide preventative antibiotics and vaccinations for close contacts. The authorities are giving great importance to this because of the two earlier deaths in Kent this year.

Jaime Morgan, from UKHSA South East, said: "We understand that news of meningococcal infection can be concerning. However, meningococcal meningitis requires very close contact to spread." She added, "We are working closely with partners and have provided public health advice to close contacts of the case."

Morgan also said that meningococcal disease is known not to spread easily among people, thus a larger possibility of public health loss is unlikely. She also urged the students at the university to be aware of symptoms and to seek medical advice if needed.

What Is Meningitis?

Meningitis is an infection of the protective membranes around the spinal cord and the brain. It can become very serious if not treated or diagnosed in time. It is a consequence of bacterial or viral infection. Despite being a rare occurrence, the infection can spread through coughs, sneezes, a cold, or physical contact in the form of kissing.

Understanding the symptoms, causes, and treatment options is important for early diagnosis and timely medical care.

Symptoms Of Meningitis

Health officials urged the public to remain alert to the warning signs of meningococcal meningitis. Common symptoms include:

• Rash
• Headache
• Neck stiffness
• Fever
• Drowsiness
• Nausea or vomiting
• Increased sensitivity to light

How is Meningitis Diagnosed?

Physicians diagnose meningitis using a combination of clinical presentation, laboratory examinations, and imaging tests. Important diagnostic tests are Lumbar Puncture (Spinal Tap), Blood Cultures, and Imaging (CT or MRI Scans).

Though Meningitis is not the only problem of the UKHSA now. Along with other global issues, the United Kingdom is also facing a certain rise in cases of botulism, which is a dreadful disease caused by bacteria and can cause difficulty in breathing, paralysis, and even death. According to the United Kingdom Health Security Agency (UKHSA), recently, two more people from Leeds have come forward with symptoms of this fatal disease.

Last week, a small number of people with symptoms of botulism presented to the National Health Service (NHS) around Leeds. These people observed botulism signs after aesthetic treatments involving botulinum toxin. After a sudden increase in patients of this dreadful disease, the authorities are on alert.

UKHSA urged people to take precautions when seeking cosmetic procedures and has advised medical staff to look out for possible botulism in people who have had recent treatments and have symptoms.
