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.

La Toya Jackson’s latest Instagram post has left fans more worried than ever. The 69 year old singer shared a series of photos earlier this week wearing a fitted red top, black pants and gold pointy heels. She added a chunky chain belt and a bracelet, posing in different angles for her followers. But what stood out most was how noticeably thin she looked, especially in the side profile shot.

Her caption was cheerful, wishing everyone a great week and sending love. The comment section quickly filled up, but instead of the usual compliments, many people expressed concern. Some fans urged others to be kind and pointed out that La Toya has always been naturally petite. Others felt something deeper might be going on. One comment read that it seemed like she may be dealing with “some health challenges”.

The post comes just weeks after La Toya shared a short, somewhat cryptic video from what looked like a doctor’s office. She did not explain why she was there but told her followers she hoped all her results would be good.

In another clip she hinted that doctor visits had become frequent, joking that she was “constantly getting check ups”. Despite the glimpses into her medical visits, she has not revealed what health issues she may be facing, leaving fans to worry and speculate.

While her situation remains private, her photos have opened up a larger conversation about what happens when someone becomes extremely thin. Many people assume being skinny is automatically healthy, but that is not always true. There is a point where being underweight can put real strain on the body.

What Really Happens When You Are Too Thin

Being underweight means your body does not have the amount of nutrition and energy stores it needs to function well. One common guideline used by experts is body mass index. For most adults, a BMI below 18.5 is considered underweight. In children and teenagers, being below the 5th percentile for BMI indicates underweight.

Sometimes extreme thinness is easy to spot, but people who have always been slim may not notice when their weight drops into an unhealthy range. Children who are underweight may simply seem smaller or leaner than others their age, which can make early signs easy to miss.

When the body does not get enough nutrients or calories, it begins to show that stress in different ways. Some of the early signs include constant tiredness, weakness, dizziness or feeling lightheaded.

The heart can also slow down, leading to a low pulse and low blood pressure. Hair may become thinner or start falling out and the immune system becomes weaker, which means a person might catch infections more easily and take longer to recover.

Emotional and hormonal changes are also common. Irritability, low mood or a sense of apathy can appear. In women, periods may become irregular or stop completely. Severe underweight can affect fertility and make it harder to get pregnant.

These symptoms do not happen overnight. They develop gradually as the body runs lower on essential nutrients. This is why sudden or unexplained weight loss should always be taken seriously.

Dave Coulier is battling tongue cancer, only months after sharing that he had overcome lymphoma. The “Full House” actor spoke about the diagnosis during an appearance on the “Today” show, describing the news as “a shock to the system.”

The 66-year-old clarified that this illness is “totally unrelated” to his earlier non-Hodgkin’s lymphoma. “This is a new cancer. I said, ‘Are you kidding me?’” he recalled. Doctors told him it may have developed from an HPV infection that could have been present for decades, which later “activated and turned into a carcinoma.”

Despite the shocking news, Coulier said the cancer is “very treatable” and comes with a “90 percent curability rate.” He added that his care team plans to begin radiation right away and that his prognosis is strong.

Dave Coulier Cancer: Dave Coulier Reveals Tongue Cancer Diagnosis

Dave Coulier is navigating another health setback soon after beating stage 3 non-Hodgkin lymphoma. Speaking on Today, the Full House star shared that he has been newly diagnosed with p16 squamous carcinoma, a form of head and neck cancer. He explained that the finding came after a routine visit and PET scan.

“Totally unrelated to the previous cancer that I had,” he said, as per PEOPLE. “So in October of this year, I went in for a PET scan, just a routine check-up, and something lit up on the scan. It turned out that I have p16 squamous carcinoma at the base of my tongue. So I asked the doctors, ‘Did this happen because of the lymphoma?’ And they said, ‘Totally unrelated.’”

What Does Tongue Cancer Look Like?

Tongue cancer can show up as a sore that refuses to heal, a red or white patch (known as erythroplakia or leukoplakia), a lump or area of thickened tissue, or a small growth on the tongue. These changes may come with bleeding that has no clear cause, numbness, pain while swallowing or talking, or a sensation of fullness in the throat. Anyone who notices these issues should speak to a doctor for proper evaluation, as explained by Mayo Clinic.

Tongue cancer develops when cells on the tongue begin growing out of control. Several forms of cancer can affect the tongue, but the most common is squamous cell carcinoma (SCC).

When the front part of the tongue is involved (the part you can see), it is called oral cancer or oral tongue cancer. When it forms on the back of the tongue, deeper in the throat, it is known as oropharyngeal cancer or base-of-tongue cancer. Mayo Clinic notes that this cancer is relatively rare, making up less than 1 per cent of new cases in the United States. Still, it is one of the more frequent head and neck cancers, occurring twice as often in men and most commonly in people aged 40 and above.

Early Symptoms Of Tongue Cancer

Early signs of tongue cancer may include long-lasting sores or ulcers, red or white patches, and a lump or thicker area on the tongue. Other symptoms can include persistent pain, trouble swallowing or speaking, and numbness or tingling inside the mouth.

Tongue Cancer Risk Factors

Researchers have identified several factors that raise the risk of tongue cancer. These are conditions or habits that can increase your likelihood of developing it. The strongest links are heavy smoking and high alcohol intake. The risk becomes much higher when both are present.

Ibuprofen is a commonly available over-the-counter painkiller that you can pick up from nearly any pharmacy or supermarket. Known for its effectiveness, it helps relieve various aches, pains, inflammation, and even symptoms linked to colds, flu, or coronavirus.

However, it’s important to remember that ibuprofen isn’t suitable for everyone. The NHS advises that people in eight key situations should avoid this anti-inflammatory (NSAID) medication, and anyone unsure should check with a pharmacist or doctor.

Ibuprofen Warning: Who Should Avoid It?

The NHS advises the following people should avoid taking ibuprofen:

• Anyone who has had an allergic reaction to ibuprofen, aspirin, or another NSAID
• Those with a stomach ulcer or a history of ulcers
• People with asthma or allergies (such as hay fever)
• Individuals with chickenpox
• Anyone with heart, liver, or kidney problems
• People with blood clotting issues
• Anyone who has previously had a stroke
• Those who are pregnant or trying to conceive

People who have had allergic reactions to ibuprofen, aspirin, or similar NSAIDs like naproxen should avoid it entirely, as should expectant mothers. Those with kidney problems, asthma, or a history of stomach ulcers should always seek medical advice before using ibuprofen, including topical forms.

The NHS adds: “How you take your medicine and the dose you use depends on the type of ibuprofen and how much it contains. Always read the packet or leaflet that comes with your medicine. Ask a pharmacist or doctor for guidance if you’re unsure about how to take it or encounter any problems. If a doctor prescribes ibuprofen, follow their instructions carefully.”

Typically, adults can take one or two 200mg ibuprofen tablets or capsules up to three times a day, leaving at least six hours between doses. In some cases, a higher dose may be prescribed, but only under a doctor’s supervision.

Medicines That Require Extra Caution

If you’re taking certain medications, consult a doctor before using ibuprofen. These include:

• Anticoagulants (such as warfarin)
• Steroid medicines
• Antidepressants
• Blood pressure-lowering medicines

The NHS has also noted: “If you’re taking ibuprofen for short-term pain, like a toothache or period pain, you may only need it for a day or two. Long-term conditions, such as rheumatoid arthritis, may require longer courses.”

Who Needs to Consult a Doctor Before Taking Paracetamol?

Paracetamol isn’t suitable for everyone either. The NHS advises that certain groups should get medical guidance before taking it:

• People on certain medications
• Anyone who has had an allergic reaction to paracetamol or another medicine
• Individuals with liver or kidney issues
• People who regularly drink more than the recommended 14 units of alcohol per week
• Those weighing less than 50kg (eight stone) may need a lower dose

Official NHS guidance, as reported by the Mirror, states: “Most people aged 16 and over can take paracetamol. It is also safe during pregnancy and breastfeeding. Paracetamol can take up to an hour to start working and its effects typically last about five hours.”
