A team of Singaporean researchers has identified a mechanism where mosquito saliva can help boost the human body`s immune response during chikungunya virus (CHIKV) infection.  The research, published in Nature Communications, showed that sialokinin -- a bioactive peptide in Aedes mosquito saliva -- binds to neurokinin receptors on immune cells and suppresses monocyte activation. This helps reduce inflammation and facilitates early viral dissemination. The findings offer new insight into how mosquito bites shape disease outcomes, said the team from the A*STAR Infectious Diseases Labs (A*STAR IDL) in Singapore. "This study provides compelling evidence that mosquito salivary proteins are not just passive carriers of viruses but active modulators of host immunity," said Dr. Siew-Wai Fong, c...

Some antihistamines -- anti-allergy drugs -- have the potential to raise dementia risk in elderly, claimed a new study on Wednesday.  Dementias are estimated to affect more than 57.4 million people worldwide -- a number that is expected to almost triple to 152.8 million cases by 2050. Early signs include memory loss, difficulty finding words, confusion, and changes in mood and behaviour. An analysis in the Journal of the American Geriatrics Society revealed that older inpatients admitted by physicians who prescribe higher amounts of first-generation antihistamines face an elevated risk of delirium (a sudden, severe state of confusion) while in the hospital. “First-generation antihistamines, such as diphenhydramine, are among the leading causes of medication-related harms in older adult...

Researchers at the Nagaland University have identified a naturally occurring plant compound called ‘Sinapic acid’ as a powerful therapeutic agent that can significantly enable wound healing in patients with diabetes.  A diabetic wound is a slow-healing sore, most often a foot ulcer. Also known as diabetic foot, it raises the risk of nerve damage (neuropathy) and poor blood circulation, foot ulcers, infections, and amputation in severe cases. The study, published in the journal Nature Scientific Reports, demonstrated that oral administration of Sinapic acid can accelerate diabetic wound healing in preclinical models. Sinapic acid is a naturally occurring antioxidant found in various edible plants. The research established that the compound works by activating the SIRT1 pathway, which pl...

In a groundbreaking advancement in breast cancer treatment, a Mumbai hospital has successfully performed a pioneering Endoscopic Skin and Nipple-Sparing Mastectomy (E-NSM).  The procedure was immediately followed by implant-based reconstruction using TiLoop mesh. Called the first-of-its-kind “scarless” mastectomy, it was conducted on a 27-year-old woman, ensuring both oncological safety and an exceptional scar-minimised outcome. When the patient first arrived at Jaslok Hospital and Research Centre in Mumbai, she had a sizeable lump measuring around 4–5 cm in the left breast. The medical team began treatment with chemotherapy to shrink the lump.  During this phase, genetic testing revealed she was BRACA gene positive, significantly increasing long-term cancer risk. Given this development...

A novel monoclonal antibody, developed by US researchers, has shown promise against malaria infection in an early clinical trial.  Researchers at the University of Maryland School of Medicine`s Center for Vaccine Development and Global Health (CVD) found that the antibody -- MAM01 -- provided dose-dependent full protection against the malaria parasite with minimal side effects. "This new monoclonal antibody could transform how we prevent malaria in young children and pregnant women," said lead author Kirsten E. Lyke, Professor of Medicine at the varsity’s School of Medicine. "Unlike vaccines that may require multiple doses or boosters, a single injection of a long-acting antibody could provide immediate, months-long protection. It`s a fundamentally different way to stop infection before...

The Air Quality Index (AQI) around Akshardham was recorded at 230, in the `Poor` category, in Delhi this morning as per the Central Pollution Control Board (CPCB). The Air Quality Index (AQI) at the Jawaharlal Nehru Stadium area recorded an AQI of 252, as seen from visuals taken near Barapullah Bridge. Raising concern regarding higher levels of AQI, pulmonologist Dr. Sharad Joshi from Ghaziabad said to ANI, "Air Quality Index (AQI) has risen significantly, leading to higher levels of particulate pollutants from sources like crop burning, vehicular exhaust, and fireworks. This exacerbates respiratory issues for those with conditions such as COPD, asthma, or a history of tuberculosis, causing symptoms like cough, fever, breathlessness, and chest pain." He added that even those without pri...

The Ahmedabad Medical Association (AMA) in collaboration with the Ahmedabad Family Physicians Association (AFPA) has unveiled a special initiative to safeguard the health of city residents, officials said on Sunday. The `Doctor on Call` Diwali Medical helpline has been launched to provide round-the-clock medical guidance and immediate treatment support to citizens during the festive period. The helpline will be operational 24/7 from October 19 to October 26, ensuring continuous access to professional medical advice throughout the week-long celebrations. The helpline is designed to assist residents with any health-related emergencies, first aid queriemedical guidances, or urgent medical guidance during Diwali, when accidents or health issues often spike due to fireworks, sweets and season...

India must treat adolescence as its "second window of growth" and invest urgently in nutrition, education and healthy food systems to avert a future health and productivity crisis, experts said at the 3rd International Conference on Public Health and Nutrition (ICPHN 2025) here this week. The conference was organised by Sukarya, an NGO working on issues of maternal and child health and nutrition, gender equality and women`s empowerment. Professor K Srinath Reddy, Chancellor of the Public Health Foundation of India, said failure to address adolescent nutrition would "lock in inter-generational poverty and poor health outcomes". "Adolescence offers a biological and social opportunity to reset health trajectories. The choices young people make now -- what they eat and how active they are -...

Diwali is here along with its festivities that not only include delicious food and drink, but also the firecrackers, which have become an inseparable part of the celebrations. Unfortunately, even as the experience of lighting them brings out the inner child in us, they affect our health in more than one way. They not only bring with them the noise pollution that startle animals, but also the smoke that actually has adverse effects on people’s health, and makes it worse for those with pre-existing respiratory problems. Mumbai doctors say they aren’t the only ones affected during this time of the year, but it is also the children, who have lungs that are still growing, but also the elderly and pregnant women, who are also vulnerable during this time of the year.   With Diwali underway and ...

An ambulance assistant of the Indian Army returning to duty from leave administered mouth-to-mouth resuscitation to an eight-month-old infant on a train and saved his life, a Defence official said on Saturday. Sepoy Sunil, posted in a field hospital of the Army in the north-east, administered cardiopulmonary resuscitation (CPR) to the infant and stabilised the baby while travelling on the New Delhi-Dibrugarh Rajdhani Express, he said. "His timely and professional action prevented a fatality in a situation where no immediate medical support was available," the Defence official said in a statement. The eight-month-old infant had developed sudden respiratory distress while travelling in the train earlier this week and became unresponsive. The mother of the child fainted as she thought the ...
