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.

Prime Minister Narendra Modi once addressed the nation through his monthly radio broadcast, Maan Ki Baat. It was the 134th installment of the broadcast, and the Prime Minister urged the people of India to take extra precautions in summer's scorching heat.

The Prime Minister said, "It is very hot in most parts of the country right now. Strong sun, hot winds, it is very important to take care of yourself in such weather. Keep drinking water. If at all you have to go out in the sun, do so with caution." He added, "Don't forget the guidelines issued by various government departments in this regard."

Then the Prime Minister also addressed traditional food and drinking practices in different parts of the country to stay fit even during the hot summer. He urged the citizens to drink regional traditional drinks to stay hydrated and named popular options like Aam Panna, Sattu sherbet, Kokum sherbet, Sol Kadhi, Panakam, Neer Mor, Sambaram, Bael Pana, and Buttermilk. "Ek Bharat Shreshtha Bharat," he added.

The Prime Minister also mentions mangoes, which are a household summer treat in India. He said, "Every region… its own mango, its own flavor, its own aroma." Then he described these different mangoes and their specialties as well.

Prime Minister Narendra Modi also mentions the journey of the Indian mangoes from domestic production to the global market.

Easy Tips To Stay Fit During a Heatwave

Drink water consistently at regular intervals instead of gulping large quantities at once. Electrolyte-rich fluids like coconut water, lemon water with a pinch of salt, or buttermilk are healthy, affordable options to soothe parched throats.

Add items like curd, rice, cucumber, and bottle gourd to your diet and avoid red meat and fried foods during peak summer days.

Extreme temperatures put additional stress on the cardiovascular system, especially in people with hypertension, diabetes, or heart conditions. Make sure to take all prescribed medications exactly as advised—don’t skip doses even if you experience heat-induced nausea. If you feel dizzy or experience palpitations or severe fatigue, consult your doctor as soon as possible.

Air conditioning is helpful, but overexposure can lead to dry skin, headaches, and respiratory discomfort. Once every two or three hours, step away from your desk for a few minutes. Walk or stand, and sip some water.

The whole world is in terror of Ebola spreading, and countries are on alert. Recently, there has been a possible Ebola-infected person under investigation by the health authorities of Brazil. As per the media reports, the suspected 37-year-old man is admitted to the hospital in São Paulo.

The person with possible Ebola infection is from the Democratic Republic of Congo and started to show Ebola-like symptoms after returning from the African country.

The local health authorities have ensured that he is in isolation, and the hospital specializes in the care of suspected or confirmed cases of the disease.

What Is Ebola?

Ebola is a severe and, in most cases, deadly disease caused by viruses predominantly found in Africa. The spread of the disease happens through contact with infected body fluids.

Some symptoms can indicate a possible infection. This includes fever, weakness, headache, muscle pain, vomiting, diarrhea, sore throat, and unexplained bleeding. This eventually leads to severe complications like bleeding, organ failure, and death. The hosts of the virus are animals like bats, primates, and antelopes.

Why Ebola Spread Is Not Like COVID

The virus is raising serious global health concerns, with Tedros Adhanom Ghebreyesus, WHO Director General, stating that the ongoing Ebola outbreak "is spreading rapidly" and "outpacing us". Yet experts say that it is not COVID and cannot spread like it.

“Ebola does NOT spread through casual airborne exposure like influenza or COVID-19. Individuals become infectious only after symptoms begin, not during the incubation period. The incubation period ranges from 2 to 21 days,” said Dr. Ishwar Gilada, Secretary General, People’s Health Organisation (India).

Experts further explained that Ebola is far more difficult to spread than airborne respiratory viruses such as influenza, COVID-19, measles, and even the Andes strain of hantavirus, which recently caused an outbreak on a cruise ship.

It is because Ebola is not airborne. Ebola does not spread through coughing, sneezing, or casual contact like shaking hands. It spreads only via body fluid contact.

In addition, people with Ebola also do not spread the virus before developing symptoms. This means that during Ebola’s incubation period, which ranges from 2–21 days, an infected person is generally not contagious, unlike COVID-19, where transmission can occur before symptoms appear.

Putting an end to speculation over US President Donald Trump’s health, the White House has announced that the 79-year-old is in “excellent health”.

Trump underwent his annual medical examination at Walter Reed National Military Medical Center on May 26.

"President Trump remains in excellent health, demonstrating strong cardiac, pulmonary, neurological, and overall physical function," Dr. Sean Barbabella, physician to the president, wrote in the memo, released late Friday evening.

He added that Trump is "fully fit to carry out all duties of the Commander-in-Chief and Head of State."

Trump’s health became a major subject of discussion after photographs at times showed swollen ankles, bruised hands, and a blotchy neck. He has been spotted several times with slurred speech and naps during official meetings.

Shortly after the examination, Trump said that "everything checked out perfectly."

Trump, who turns 80 in June, is the oldest person to assume the presidency. He frequently portrays himself as more energetic and fitter than Joe Biden, his Democratic predecessor, who left office last year at age 82 after facing questions about his fitness for the job.

Barbabella described the assessment as a “comprehensive preventive evaluation,” which included a thorough review of all diagnostic studies and laboratory testing conducted over the past year.

It also included “consultations with twenty-two specialty providers from multiple academic institutions. All aspects of the assessment were performed in accordance with US Preventive Services Task Force recommendations,” he said in the memo.

Diagnostic Summary

The President’s diagnostic summary showed:

• Vision is normal.
• Hearing is intact, and teeth are in very good condition.
• The thyroid and lymph nodes are normal. An ultrasound of the carotid arteries showed normal results.
• The lungs and chest demonstrated no abnormalities.
• Coronary CT angiography demonstrated no arterial obstruction or structural abnormalities of the heart or major vessels.
• An echocardiogram showed no abnormalities. Cardiac function is normal, and circulation to the extremities remains intact.
• Gastrointestinal/abdominal and genitourinary examinations were normal.
• Slight lower leg swelling was noted, with improvement from last year.

Barbabella further said that the medical test also evaluated his hands and “revealed ecchymosis (bruising), consistent with minor soft tissue irritation related to frequent handshaking in the setting of aspirin use for cardiovascular prevention". He added that it is “a common and benign effect of aspirin therapy.”

The examination also found no “suspicious lesions or concerning growths.”

Neurological Health

The President's neurological condition was significantly targeted, with many doctors pointing out that he's suffering from dementia. But the test results, authorized by the President for public release, revealed him to be in “normal mental status".

Further, it showed that his "cranial nerves are intact", and he also has "normal motor strength, sensation, reflexes, gait, and balance.”

Trump also completed the Patient Health Questionnaire-9 (PHQ-9) and Generalized Anxiety Disorder-7 (GAD-7) screenings for depression and anxiety, both of which were "normal".

Cognitive function, assessed using the Montreal Cognitive Assessment (MoCA), was also within normal limits, with a score of 30 out of 30.

Lab Results

Comprehensive laboratory evaluation, including a complete blood count, comprehensive metabolic panel, coagulation profile, D-dimer, B-type natriuretic peptide, and cardiac biomarkers, remained within normal limits, Barbabella said.
