How does air pollution affect heart? Sree Chitra to find out with purifiers
THIRUVANANTHAPURAM: Over the next year, 200 heart patients in Kerala will sleep with a drum-sized cylindrical air purifier beside their beds. This is part of a major study being undertaken by the Sree Chitra Tirunal Institute for Medical Sciences and Technology (SCTIMST) to explore the link between indoor air pollution and heart health.
The air purifiers -- supplied by the All India Institute of Medical Sciences (AIIMS), New Delhi -- will continuously monitor indoor air quality even as clinicians track each patient's heart condition. The goal: to understand whether cleaner indoor air can reduce complications in people suffering from heart failure.
The Kerala-based project is part of a larger multi-centre research initiative involving AIIMS, New Delhi, and the Dayanand Medical College, Ludhiana, in Punjab -- regions known for far worse air quality than Kerala. Funded by the Indian Council of Medical Research (ICMR), the study is significant as cardiovascular disease remains the leading cause of death in India.
'Air pollution is not just a city or traffic issue. Indoor air, where people spend a majority of their time, can be just as hazardous, especially for those with heart failure,' Dr Harikrishnan S, principal investigator and professor of cardiology at SCTIMST, told TNIE.
'This study asks a crucial question: can reducing indoor air pollution improve outcomes for patients with heart failure?'
Each home will be equipped with one of two types of purifiers, distributed randomly. One has a basic bacterial filter while the other comes with both bacterial and dust filters. The devices will measure pollutants from environmental sources and household practices such as cooking.
'Patients will return for clinical review every three months, during which doctors will assess changes in their heart function, specifically the heart's pumping efficiency,' Dr Harikrishnan said.
A baseline reading from a central monitor installed at SCTIMST will help interpret the data collected by the homebased machines.

Centre, state sign MoU to boost animal disease laboratory in Pune
In a major step towards strengthening animal disease control infrastructure in western India, the central and state governments on Wednesday signed a memorandum of understanding (MoU) to provide financial support to the Bharat Ratna Atal Bihari Vajpayee state-level Animal Disease Investigation Laboratory in Pune, said officials on Friday. The agreement was signed between the department of animal husbandry and dairying, Government of India, and the department of animal husbandry, dairy development and fisheries, Government of Maharashtra in Delhi. It aims to enhance the laboratory's capabilities in disease diagnosis and surveillance across several states and union territories, said officials. The Pune-based laboratory has been serving as the regional disease diagnostic laboratory (RDDL) for the western zone since 2000 covering five states—Maharashtra, Gujarat, Madhya Pradesh, Chhattisgarh, Goa—and two union territories—Dadra and Nagar Haveli, and Diu-Daman. Dr Ramaswami N, secretary, animal husbandry, dairy development and fisheries (AHDDF) said steps are being taken to get National Accreditation Board for Testing and Calibration Laboratories (NABL) accreditation for the laboratory and the state's veterinary biological production unit has received GMP (good manufacturing practices) certification. The MoU is subject to review and renewal every five years.

Maha's anti-venom pioneer targeted by predatory journal
Mumbai: The world of medical research is battling its own version of cyber frauds: predatory or 'pseudo' journals, deceptive publications that claim to be scholarly but rarely follow ethical publishing practices and seek hefty payment from authors. On Friday, Dr Himmatrao Bawaskar (75), a Mahad-based physician who won a Padma Shri in 2022 and is known for his rural Maharashtra medical practice and research, wrote in 'The Lancet' about his two-year struggle with a predatory journal that swiftly published his work, then started demanding 1,000 pounds and issued threats when he objected. "I received threatening emails stating they would take serious action and damage my reputation in India," he said. Mahad-based Dr Himmatrao Bawaskar, whose pioneering work in anti-venom for scorpions and snakes has been published in numerous peer-reviewed medical journals, was so "devastated" by his struggle with a predatory journal that he developed "anxiety, insomnia and palpitation". Within six months, the 75-year-old doctor lost 8 kgs and needed psychiatric help. In recent months, various medical associations across the world have voiced concern about the growing number of predatory journals. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Tausende schwärmen von diesem Nagelpilz-Gerät – wir haben es überprüft Med-Aktuell Undo The International Committee of Medical Journal Editors in Feb estimated there are over 15,000 such journals. While medical research paves the way for new treatments, these journals are undermining its credibility. Dr Bawaskar's ordeal began when he submitted his self-funded diabetes research to high-impact journals. After many rejections, a case report journal approached him. "In my submission to this journal, I stated I work without funding and would not be able to pay fees," he said. Yet the journal sent him a proof in a couple of days. "I was shocked—how could the peer review and publication process be completed so quickly? I again appealed, stating my inability to pay. The journal ignored my requests and proceeded to publish the article, then sent me an invoice with exorbitant fee," he added. The journal then sent threats and said they were giving him "a 40% discount." "But during a call with my son who is a cardiologist in the US, my wife mentioned my stress to him," said the doctor. His son identified the predatory nature of the journal and blocked their communications. While the doctor hasn't paid the journal, this experience has prompted him to work out a checklist. He said, "Since this episode, I have not attempted to publish again. Instead, I find fulfilment in seeing my patients recover and walk again—living testaments to my diagnosis and management; these are my true publications."

City Docs Save Woman With Congenital Heart Defect Without Open Surgery
Nagpur: In a groundbreaking development, Nagpur-based doctors performed a rare and highly advanced heart procedure that saved a young woman's life — without open heart surgery. The patient, born with a complex congenital heart defect known as Blue baby syndrome (Tetralogy of Fallot or TOF), a condition wherein a baby's skin turns bluish due to lack of oxygen in blood, had undergone a major open-heart surgery as a child. Now an adult, she recently became severely unwell due to a leaking heart valve and needed another major surgery. Instead of undergoing another high-risk open-heart operation, she received a minimally invasive treatment — much like angioplasty — through a vein in her leg. Incredibly, the patient was able to walk and talk just an hour after the procedure and was ready to go home within 24 hours. This life-saving and rare procedure, known as Transcatheter Pulmonary Valve Implantation, was successfully carried out by Dr Manish Chokhandre, senior interventional paediatric cardiologist at Arneja Heart Institute. "Redo open-heart surgeries are extremely risky, especially in adults with childhood congenital heart conditions," explained Dr Chokhandre. "We carefully studied the patient's unique heart structure, custom-designed a special valve, and performed the entire procedure without opening the chest. " Welcoming the advancement, Dr Amar Amale, president of Cardiological Society of India (CSI), Vidarbha chapter, said, "Gone are the days when children had to undergo open-heart surgery with large chest incisions. Paediatric cardiology has advanced to a level where even a complex congenital heart condition in an adult, who earlier had childhood surgery, can now be treated through a simple leg vein — just like an angioplasty. It's a huge leap in cardiac care." "Paediatric cardiology needs more attention. One in every 100 children is born with a heart defect. Many go undiagnosed or are diagnosed too late," said Dr Chokhandre, who regularly performs heart procedures on newborns. Veteran cardiologist Dr Jaspal Arneja said, "Thanks to medical advances and new technologies, even complex heart problems can be treated more safely. With artificial intelligence (AI) helping us understand heart function better, we can now offer more accurate and effective treatment." This successful case from Nagpur brings hope to hundreds of children and adults born with heart defects — and shows how medical science and skillful execution are transforming lives, one heartbeat at a time.
