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.

Law on assisted dying will soon be passed in Jersey as politicians approved the principles to allow the same. On Wednesday. States member approved the draft law that would enable people with a terminal illness and experiencing incurable suffering to end their life with the help of a medical professional.

The Assisted Dying Review Panel said that they would need to take a closer look at the details before the law is finalized. The law is expected to be debated again on February 24 after the scrutiny panel is done with reviewing the details.

The draft law has been approved with 32 votes for and 14 votes against. This was similar to the result when the first details of the assisted dying law was given a green light in May 2024. The vote also followed the approval of an end of life care law, which was passed on Tuesday. This required the island's health minister to prove end of life care for the last 12 months of anyone's life.

Law For Assisted Dying: What Does It Mean For Jersey?

Humanists UK chief executive Andre Copson said, and as is reported by the BBC, "This vote in favour of the draft law represents a historic moment for Jersey, and a huge step forward for compassion, dignity and choice at the end of life. The proposals contain strong safeguards and reflect the clear wishes of the public, who have spoken through citizens' juries and repeated surveys. Today, members of the States Assembly have listened to those voices and are one step closer to bringing choice and compassion to those facing the hardest of circumstances."

As a rebuttal, Christian leaders on Sunday led a prayer outside the States building. Organizers of Walk for Life said the prayer was attended by 200 people who were there to share their "great concern for the unintended consequences of the introduction of assisted dying, that has been expressed over the last few years."

Law For Assisted Dying In Jersey: What It Proposes?

As per the official government website of Jersey, the law is for those with a terminal illness, who is experiencing or is expected to experience unbearable physical suffering. Under such scenario the person "chooses to end their life with the help of a medical professional". The website notes that it is not same as suicide. It is a "service provided to people in certain limited circumstances that will be set out in law".

The website also notes that this does not replace palliative care and end of life care services. As person approaching the end of their life or living with serious illness should be provided the care and treatment they need to maximize their quality of life and minimize any suffering or distress. "Assisted dying is an additional choice that some people may make because they want more control over the manner and timing of their death," notes the website.

Assisted Dying or Euthanasia Vs Assisted Suicide

The difference between euthanasia and assisted suicide depends on who is administering the lethal dose. In an assisted suicide, the patients administer a lethal dose themselves.

The bill furthermore places no time limit on life expectancy, unlike similar laws do in the US, Australia, and New Zealand.

The bill states that anyone with an incurable illness that cause them "unbearable suffering" can request euthanasia, even if the illness is not terminal. The catch is, applicants must be mentally competent, and two doctors must be required to rule that they are psychologically fit enough to take the decision for themselves.

What Is Euthanasia?

The term has Greek origins, which means "good death", and refers to the practice under which an individual intentionally ends their life, painlessly. However, there are various types of Euthanasia, which are as followed:

Active Euthanasia: Where a patient is injected with a lethal dose of the drug, also known as "aggressive" euthanasia.

Passive Euthanasia: Where the patient's artificial life support such as a ventilator or feeding tube is withheld.

Voluntary Euthanasia: This happens when the patient consents to it.

Involuntary Euthanasia: This happens when the patient is not in the state to consent to euthanasia. In such cases, the patient's family makes the decision.

Lori Coble died of brain cancer at 48. Mom of teenage triplets, who had lost her first three children in a car accident died on Wednesday, January 21, confirmed a family friend to PEOPLE. She told PEOPLE "Lori passed away last night surrounded by her family."

In 2007, Lori lost her three children Kyle Christopher, 5, Emma Lynn 4, and Katie Gene, 2, in a car crash. While she and her husband Chris spent months coping up, they had triplets the year after the accident. Each carried an older sibling's middle name: Jake Christopher, Ahley Lyn, Ellie Gene.

Lori Coble's Brain Cancer Diagnosis

In June 2025, Chris noticed something was wrong with his wife, as she was "getting more clumsy". She would run into walls, stub her toe on chairs, or drop drinking glasses on the floor. By early July, stroke like symptoms too appeared. In a previous interview with PEOPLE, he said, "Her mouth started to droop a little bit. It became too much to ignore."

By July, Lori was diagnosed with a large and aggressive stage 4 glioblastoma or brain cancer. "I was hoping we were done with the life changing, life altering disasters when life as you knew it yesterday is gone," Chris said. He said he started mourning loss of his wife the day she got diagnosed.

"I didn’t have a lot of hope at the outset — and that weighed heavily on me. I was really upset, mad, angry. How could this be happening to us again?”

While Lori had two surgeries to remove the tumor in the period of next few months, the second surgery was invasive and caused her to lose control of her left side. Few days after, she had a stroke and was placed in a medically induced coma. She was in the hospital for 40 days. After she regained her strength, she returned home, and started radiation and chemotherapy. The treatment however made her more tired and impacted her speech. She was getting worse by every passing day.

It was in mid-November when Lori was again in the hospital, this time in the ER, and doctors discovered a brain infection and advised on surgery. "You feel like she's just being tortured. I'm not sure that the treatment for cancer in this situation is any better than the disease itself.”

She also suffered with a lung infection and pneumonia and was brought back in the hospital. She was finally brought home for hospice care.

What Is Glioblastoma?

As per MD Anderson Cancer Center, glioblastoma is the most common and most aggressive form of primary brain cancer. In US, every year, around 12,000 new cases are detected. All glioblastomas are classified as grade IV tumors, which means they contain the most abnormal looking cells that grow rapidly.

Glioblastoma develops from star-shaped brain cells known as astrocytes, which play a key role in nourishing the brain and shielding it from harmful substances in the bloodstream.

Astrocytes belong to a larger group called glial cells. These cells support the brain’s structure, supply nutrients, protect neurons, and help maintain a stable chemical balance in the brain.

The tumour most often forms near the front of the brain or close to its lower regions, though it can arise anywhere. The frontal lobe controls speech, movement, behaviour, and memory, while the temporal lobe is involved in memory formation, language, and processing sensory information such as sound and sight.

Colorectal cancer is the leading cause of cancer deaths in American under 50. A new study from the American Cancer Society revealed that while the deaths by various cancers in Americans under age 50 have fell overall, a notable exception rose in colorectal cancer deaths. The study analyzed over 1.2 million deaths from cancer between 1990 and 2023. The researchers found that colorectal cancer deaths increased a little over 1% annually. This has made it the top cause of cancer death in men and women combined. The findings are published in the peer-reviewed medical journal JAMA.

Other causes of cancer deaths in people under 50, including leukemia and breast cancer, decreased up to 6% annually. The chief science officer of the American Cancer Society, also an oncologist, Dr William Dahut said better treatment is helping people live longer. Speaking to ABC News, he said, "My sense is, if you would break down the improvements, more than half of it is certainly due to better therapies."

Decrease In Tobacco Use = Decrease In Lung Cancer

He also said that there has been a decrease in tobacco use, which has helped drive a 5.7% annual decline in lung cancer deaths. In 1990, lung cancer was the leading cause of cancer death among people under 50, but now it ranks fourth.

What Other Cancer Deaths Decreased

While the study showed that more women are diagnosed with breast cancer, the deaths have decreased by an average of 1.4% per year. However, it continues to remain the leading cause of cancer death in younger women.

Cervical cancer deaths too decreased about half a percentage every year. This is the third leading cause of cancer deaths in young women.

“I think there’s a good chance we see dramatic decreases [in cervical cancer deaths], assuming vaccination rates continue,” Dr. Dahut predicted

What Is Colorectal Cancer?

The American Cancer Society notes that colorectal cancer is a cancer that starts in the colon or the rectum. Colorectal cancer impacts around 1.9 million people every year, noted the World Health Organization (WHO) as per its 2022 data.

It is a disease of large bowel and a type of cancer that originates from the rectum or colon. A person's colon, cecum, rectum and anus make up the large intestine.

The ileocecal valve that is located at the opening between the ileum and the large intestine controls the flow of chyme from the small intestine to the large intestine. It happens when abnormal cells invade the wall of the rectum and neighboring tissue. These are called polyps or growths in the inner lining of the colon.

Experts are concerned about the rising colorectal cancer deaths in young Americans, mostly because they are unsure of why is this happening. However, Dahut said, "It didn’t totally surprise me, although I would have to say it’s moving a little more quickly than I anticipated. It’s going to be linked to either environmental [causes] or a lifestyle.”

Dahut also noted that doctors should regularly recommend screening for the disease and following up with the symptoms, even in middle-aged parents. This is more important as more than 75% of new colorectal cancer diagnoses in young patients are found in later stages. “Lots of folks in their 40s do not necessarily have a primary care doctor telling them to get the screening – men in particular,” he said.
