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.

UK Prime Minister Keir Starmer is preparing to announce a crackdown on children's access to social media within days. A speech from the prime minister, which is expected to include a new policy on social media, is planned for next week.

The UK is the latest country considering restrictions on social media use among those under the age of 16 amid growing concerns about mental health, online abuse, and child protection.

Several countries have introduced or proposed regulations on children's access to social media as concerns mount over the impact of these platforms on young people's health and safety.

A look at the countries planning to implement social media ban:

Australia: Banned social media for children under 16, including TikTok, Instagram, Facebook, and YouTube.

China: Uses a "minor mode" system that limits screen time and access based on a child's age.

Denmark: Plans to ban social media for children under 15, with limited parental exceptions for those aged 13–14.

France: Approved a bill to ban social media for children under 15, pending final legislative approval.

Germany: Children aged 13–16 can use social media only with parental consent.

Greece: Preparing to introduce a social media ban for children under 15.

India: Karnataka has banned social media for children under 16. Other states like Andhra Pradesh, Goa, and Bihar are considering age restrictions.

Italy: Children under 14 need parental consent to create social media accounts.

Malaysia: Barred users under 16 from registering new social media accounts.

Norway: Proposed raising the minimum age for social media consent from 13 to 15 and introducing a 15-year minimum age limit.

Poland: Drafted legislation to ban social media for children under 15 and require age verification.

Slovenia: Preparing a law that would prohibit social media access for children under 15.

Spain: Plans to ban social media access for minors under 16 and require age verification.

Sweden: A government commission has recommended a minimum social media age of 15.

Turkey: Passed legislation banning social media use by children under 15.

United States: Several states require parental consent for minors, while federal legislation seeks stronger protections for young users.

European Union: Considering stricter child safety rules, including parental consent for under-16s and a ban for children under 13.

Will A Blanket Ban on Social Media Work?

Blocking children from social media is no substitute for making platforms safe in the first place, the UN human rights office warned last month.

"Online harms to children's safety, privacy, and wellbeing result from design choices and business practices that undermine safety, including addictive features such as infinite scroll, autoplay, and persistent notifications," said UN High Commissioner for Human Rights Volker Türk.

Türk cautioned that such bans can be easily circumvented and risk pushing children towards riskier, less-monitored spaces.

"Simply limiting access to platforms that remain unsafe cannot stand as the endpoint," he said.

The UN Office also issued a 10-point framework urging governments and technology companies to go further and faster in protecting children online. The guidelines, titled Getting Children's Safety Online Right, come as age-based social media restrictions proliferate worldwide. It includes:

• Embedding child safety measures directly into platform design from the outset.

• Not leaving parents and children solely responsible for managing online risks.

• Conducting mandatory child-rights impact assessments for digital platforms.

• Implementing tightly regulated age-verification systems to protect privacy.

• Consulting children meaningfully when developing online safety regulations and policies.

"The intent to protect young minds from addiction, misinformation, and harmful content is welcome. However, effectiveness will depend less on restricting children and more on regulating platforms," Dr. Rajendra Pratap Gupta, Chairman of Health Parliament, creator of SHE App, and former adviser to the Union Health Minister, told HealthandMe.

"Stronger platform accountability, age-appropriate design, and algorithmic responsibility are crucial. Combined with digital literacy and parental awareness, oversight and control, such measures can create a healthier digital ecosystem. Without platform control, regulations risk remaining largely symbolic," Dr. Gupta said.

West Bengal today became the 36th state to implement the Indian government's flagship health insurance scheme, Ayushman Bharat Pradhan Mantri Jan Arogya Yojana (AB PM-JAY).

The scheme aims to achieve universal health coverage and ensure seamless access to quality healthcare for every eligible citizen across the country.

The National Health Authority (NHA), under the Union Ministry of Health and Family Welfare (MoHFW), signed a Memorandum of Understanding (MoU) with the Department of Health and Family Welfare, Government of West Bengal, for the implementation of AB PM-JAY in the state.

Over 12 Crore Treatments Availed Under PM-JAY

“Beneficiaries under the AB PM-JAY scheme have availed over 12 crore treatments worth more than Rs 1.82 lakh crore, providing substantial financial protection to poor and vulnerable families,” said JP Nadda, Union Health Minister.

He noted that one of the most significant outcomes of the government's efforts has been the reduction in out-of-pocket healthcare expenditure, which has declined from 64.6 per cent before 2018 to 43.4 per cent today.

Nadda further stated that AB PM-JAY has enabled timely access to quality healthcare through a cashless, paperless, and fully digital platform.

Referring to findings published in The Lancet, he noted that nearly 90 per cent of eligible cancer patients under the scheme were able to access treatment within 30 days, demonstrating the program's role in improving timely healthcare access.

Chief Minister of West Bengal Suvendu Adhikari noted that under the National Health Mission has recently released Rs 527 crore to the state, which will further support healthcare infrastructure and service delivery.

The scheme will cover:

• 1.43 crore families in total
• 1.24 crore eligible beneficiary families
• Around 3.06 lakh families of ASHAs, Anganwadi workers, and helpers
• Nearly 15.95 lakh families of senior citizens aged 70 years and above

Anupriya Patel, Minister of State for Health and Family Welfare, said that AB PM-JAY is not merely a health scheme but a transformative initiative that has brought financial protection and healthcare security to millions of vulnerable families across India.

She noted that AB PM-JAY, "now covers more than 62 crore people, including poor and vulnerable families, senior citizens aged 70 years and above, and gig and platform workers" in India.

Achievements include:

• More than 44 crore Ayushman Cards have been created.
• Over 12 crore hospital admissions have been authorised under the scheme.
• Women are accounting for nearly half of all beneficiaries.

Ayushman Bharat PM-JAY was launched in September 2018 and has since emerged as the world's largest government-funded health assurance programme.

The scheme provides health coverage of Rs 5 lakh per family per year for secondary and tertiary care hospitalization. It covers around 12 crore families, representing the bottom 40 per cent of India's population.

The program was later expanded to include 6 crore senior citizens aged 70 years and above, belonging to 4.5 crore families, irrespective of their socio-economic status.

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.
