A newly developed artificial intelligence (AI) tool, that uses data from the low-cost electrocardiogram (ECG), may be more accurate in identifying hidden heart disease than cardiologists, according to US researchers.

Structural heart disease, including valve disease, congenital heart disease, and other issues that impair heart function, affects millions of people worldwide. These often remain undetected due to lack of a routine and affordable screening test.

To address the gap, a team from Columbia University in the US has developed an AI-powered screening tool, EchoNext, that detects structural heart diseases using ordinary ECG data.

EchoNext identifies patients who should have an ultrasound (echocardiogram) -- a non-invasive test that is used to diagnose structural heart problems. In the study, published in the journal Nature, the tool was found to be more accurate than cardiologists.

A 32-year-old man on Wednesday tested positive for Nipah and is currently under treatment at the Palakkad Medical College hospital. Notably, his father recently passed away and was Nipah positive.

The test results came out on Wednesday.

The test was done at a centre in Malappuram district.

The timing of eye contact is key to how we communicate with both humans and robots, revealed a study led by Australian researchers on Wednesday.

Researchers from Flinders University found that not just making eye contact, but when and how it's done, fundamentally shapes how we understand others, including robots, according to a statement from the HAVIC Lab (Human, Artificial + Virtual Interactive Cognition), news agency reported.

"Our findings have helped to decode one of our most instinctive behaviours and how it can be used to build better connections, whether you're talking to a teammate, a robot, or someone who communicates differently," said cognitive neuroscientist Nathan Caruana, who led the HAVIC Lab.

In a study with 137 participants, researchers found that a specific gaze sequence -- looking at an object, making eye contact, then returning to the object -- was the most effective non-verbal way to signal a request for help.

Indians consume salt 2.2 times more than the amount recommended by the World Health Organization (WHO), posing severe health risks such as hypertension, strokes, and kidney disease, among others, according to ICMR's National Institute of Epidemiology.

WHO recommends less than 5 grams per day of salt (roughly under a teaspoon) or below 2g of sodium per day.

However, “the mean salt consumption per day by an Indian is 11 grams per day, which is 2.2 times more than the WHO recommendation”, the ICMR-NIE said.

According to the apex research body, regular iodised salt contains 40 per cent of sodium, much higher than the WHO limit. The WHO also suggests the use of low-sodium salt to ward off the risk.

Hearing loss combined with the feelings of loneliness accelerates cognitive decline, leading to dementia in older adults, according to a study.

Researchers from the University of Geneva (UNIGE) in Switzerland showed that isolation, communication difficulties, reduced alertness, and hearing impairment or loss are a real challenge in daily life.

The findings, published in the journal Communications Psychology, showed that hearing loss accelerates cognitive decline, particularly among individuals who feel lonely, regardless of whether they are socially isolated.

‘‘We found that people who were not socially isolated but who felt lonely saw their cognitive decline accelerate when they were deaf,’’ said Matthias Kliegel, professor in the Cognitive Ageing Laboratory in UNIGE.

Severity of menopause symptoms and lack of emotional support are likely reasons why some women experience depression during early menopause, finds a study on Wednesday.

Premature menopause, medically known as premature or primary ovarian insufficiency (POI), is a condition in which the ovaries cease to function normally before the age of 40. It has been linked to an elevated lifetime risk for depression and anxiety.

Affected women not only experience the effects of oestrogen deficiency, but they also experience the unanticipated loss of reproductive function. However, some women are more adversely affected by depression and anxiety by these changes than others.

The study, published online in the journal Menopause, suggests that risk factors include younger age at diagnosis, severity of menopause symptoms, lack of emotional support, and fertility-related grief.

“The high prevalence of depressive symptoms in those with POI highlights the importance of routine screening in this vulnerable population,” said Dr. Monica Christmas, associate medical director for The Menopause Society.

The central government on Tuesday denied media reports which claimed that the Ministry of Health has issued health warnings on Indian snacks such as samosas, jalebi, and laddoo to fight obesity crises in the country.

It noted that the warning labels on food issued by the Ministry of Health are “not selective towards Indian snacks”.

“Some media reports claim that the @MoHFW_INDIA has issued a health warning on food products such as samosas, jalebi, and laddoo. This claim is fake. The advisory of the Union Health Ministry does not carry any warning labels on food products sold by vendors, and has not been selective towards Indian snacks,” the Ministry of Health said.

Media reports claimed that the Union Health Ministry has urged all ministries, departments, and autonomous bodies to display warnings on Indian snacks like samosa, vada pav, kachori, and jalebi.

In an effort to promote healthy eating habits and raise awareness about food safety among students, the Food Safety Department of Tamil Nadu will soon install ‘oil, sugar, and salt’ boards in all educational institutions across Coimbatore district.

The initiative is aimed at combating rising levels of childhood obesity and non-communicable diseases (NCDs) by educating students on the harmful effects of high-fat, high-sugar, and high-salt diets.

These boards, developed by the Food Safety and Standards Authority of India (FSSAI) in collaboration with the Indian Council of Medical Research-National Institute of Nutrition (ICMR-NIN), will feature informative posters and digital displays.

They will highlight the recommended daily intake of sugar, salt, and oil, and explain how excess consumption can adversely impact health, including increasing the risk of obesity, type-2 diabetes, and cardiovascular diseases.

To make the messages more appealing and accessible to children, the boards will feature attractive illustrations and cartoons. Officials believe this visual approach will help students easily understand the concepts of food safety and nutrition.

संयुक्त राष्ट्र की एजेंसियों, विश्व स्वास्थ्य संगठन (WHO) और यूनिसेफ द्वारा मंगलवार को जारी नए राष्ट्रीय टीकाकरण कवरेज आंकड़ों के अनुसार, दुनिया भर में 1.4 करोड़ से ज़्यादा बच्चों को 2024 में किसी भी टीके की एक भी खुराक नहीं मिली।

रिपोर्ट से पता चला है कि पिछले साल लगभग 2 करोड़ शिशुओं ने डिप्थीरिया, टेटनस और पर्टुसिस (DTP) युक्त टीके की कम से कम एक खुराक नहीं ली, जिससे दशकों की प्रगति पर खतरा मंडरा रहा है।

3 करोड़ से ज़्यादा बच्चे खसरे से भी पूरी तरह सुरक्षित नहीं हैं, जिसके कारण और भी बड़े या विनाशकारी प्रकोप सामने आ रहे हैं।

2024 में, बड़े या विनाशकारी खसरे के प्रकोप का सामना करने वाले देशों की संख्या तेज़ी से बढ़कर 60 हो गई, जो 2022 के 33 से लगभग दोगुनी है।

रिपोर्ट में टीकाकरण सेवाओं तक सीमित पहुँच, बाधित आपूर्ति, संघर्ष और अस्थिरता, या टीकों के बारे में गलत जानकारी के कारण बच्चों का टीकाकरण न हो पाना या कम टीकाकरण होना बताया गया है।

More than 14 million children worldwide did not receive a single dose of any vaccine in 2024, according to new national immunisation coverage data released on Tuesday by the UN agencies World Health Organization (WHO) and UNICEF.

The report showed that nearly 20 million infants missed at least one dose of diphtheria, tetanus, and pertussis (DTP)-containing vaccine last year, threatening to unwind decades of progress.

More than 30 million children also remained under-protected against measles, leading to more large or disruptive outbreaks.

In 2024, the number of countries experiencing large or disruptive measles outbreaks rose sharply to 60, nearly doubling from 33 in 2022.

The report blamed limited access to immunisation services, disrupted supply, conflict, and instability, or misinformation about vaccines for children remaining un or under-vaccinated.
