Siddaramaiah's Covid vaccine link to Hassan heart attack deaths busted by health experts
The show also discusses the importance of preventive healthcare and early screening for heart disease. Additionally, Infosys has issued caution emails to employees working more than 9 hours and 15 minutes a day for five days a week, emphasising the importance of work-life balance. This move contradicts co-founder Narayana Murthy's recent controversial statement urging Indians to work 70 hours a week. The company's stance prioritises employee well-being and long-term productivity over excessive work hours. The shift comes amid rising health concerns amongst young tech professionals, including cardiac issues and burnout linked to long working hours. In a separate development, an Infosys employee in Bengaluru has been arrested for allegedly recording videos of 30 women employees in the restroom.

Why India's hepatitis crisis needs urgent attention
World Hepatitis Day, observed on July 28, is a global call to action to eliminate viral hepatitis, the second deadliest infectious disease after COVID-19. This year's theme, 'Hepatitis: Let's Break It Down', urges the dismantling of financial, social, and systemic barriers that delay timely diagnosis, treatment, and prevention of this silent killer. Understanding hepatitis Hepatitis refers to inflammation of the liver, primarily caused by five viruses: A, B, C, D, and E. Hepatitis A and E are transmitted through contaminated food or water and usually result in acute illness. Hepatitis B, C, and D, however, are more insidious and are transmitted through blood, unsafe medical procedures, unprotected sex, or from mother to child. If left untreated, these can lead to chronic liver disease, cirrhosis, or liver cancer. According to the World Health Organization's 2024 Global Hepatitis Report, India bears the world's second-highest burden, with 2.98 crore Hepatitis B and 55 lakh Hepatitis C cases. Alarmingly, nearly 90% of those infected are unaware of their condition and often present only when irreversible liver damage has set in. Despite the availability of vaccines for Hepatitis A and B, and curative treatments for Hepatitis C, hepatitis still claims one life every 30 seconds. Challenges that need addressing In line with the WHO's target to eliminate viral hepatitis as a public health threat by 2030, India must address pressing challenges such as high diagnostic costs, limited screening, and persistent stigma. Strengthening the healthcare response through routine screening, community-level education, and policies that ensure affordable access to diagnostics and treatment is essential. Across the country, public health institutions, medical colleges, and civil society partners are intensifying efforts through awareness campaigns, screening programs, and policy advocacy to improve access to diagnosis and treatment. Recent initiatives have included national summits bringing together experts and stakeholders to develop comprehensive elimination strategies. On this World Hepatitis Day, let's break the silence, end the stigma, and build a hepatitis-free world. Join the movement. Get tested, get treated, and protect your family.

Long-Covid, viruses: New research looks for links to chronic fatigue
Millions of people who recover from infections like Covid-19, influenza and glandular fever are affected by long-lasting symptoms. These include chronic fatigue, brain fog, exercise intolerance, dizziness, muscle or joint pain and gut problems. And many of these symptoms worsen after exercise, a phenomenon known as post-exertional malaise. Medically the symptoms are known as myalgic encephalomyelitis or chronic fatigue syndrome (ME/CFS). The World Health Organization classifies this as a post viral fatigue syndrome, and it is recognised by both the WHO and the United States Centers for Disease Control and Prevention as a brain disorder. Experiencing illness long after contracting an infection is not new, as patients have reported these symptoms for decades. But Covid-19 has amplified the problem worldwide. Nearly half of people with ongoing post-Covid symptoms – a condition known as long-Covid– now meet the criteria for ME/CFS. Since the start of the pandemic in 2020, it is estimated that more than 400 million people have developed long-Covid. To date, no widely accepted and testable mechanism has fully explained the biological processes underlying long-Covid and ME/CFS. Our work offers a new perspective that may help close this gap. Our research group studies blood and the cardiovascular system in inflammatory diseases, as well as post-viral conditions. We focus on coagulation, inflammation and endothelial cells. Endothelial cells make up the inner layer of blood vessels and serve many important functions, like regulating blood clotting, blood vessel dilation and constriction, and inflammation. Our latest review aims to explain how ME/CFS and long-Covid start and progress, and how symptoms show up in the body and its systems. By pinpointing and explaining the underlying disease mechanisms, we can pave the way for better clinical tools to diagnose and treat people living with ME/CFS and long-Covid. What is endothelial senescence? In our review, our international team proposes that certain viruses drive endothelial cells into a half-alive, 'zombie-like' state called cellular senescence. Senescent endothelial cells stop dividing, but continue to release molecules that awaken and confuse the immune system. This prompts the blood to form clots and, at the same time, prevent clot breakdown, which could lead to the constriction of blood vessels and limited blood flow. By placing 'zombie' blood-vessel cells at the centre of these post-viral diseases, our hypothesis weaves together microclots, oxygen debt (the extra oxygen your body needs after strenuous exercise to restore balance), brain-fog, dizziness, gut leakiness (a digestive condition where the intestinal lining allows toxins into the bloodstream) and immune dysfunction into a single, testable narrative. From acute viral infection to 'zombie' vessels Viruses like SARS-CoV-2, Epstein–Barr virus, HHV-6, influenza A, and enteroviruses (a group of viruses that cause a number of infectious illnesses which are usually mild) can all infect endothelial cells. They enable a direct attack on the cells that line the inside of blood vessels. Some of these viruses have been shown to trigger endothelial senescence. Multiple studies show that SARS-CoV-2 (the virus which causes Covid-19 disease) has the ability to induce senescence in a variety of cell types, including endothelial cells. Viral proteins from SARS-CoV-2, for example, sabotage DNA-repair pathways and push the host cell towards a senescent state, while senescent cells in turn become even more susceptible to viral entry. This reciprocity helps explain why different pathogens can result in the same chronic illness. Influenza A, too, has shown the ability to drive endothelial cells into a senescent, zombie-like state. What we think is happening We propose that when blood-vessel cells turn into 'zombies', they pump out substances that make blood thicker and prone to forming tiny clots. These clots slow down circulation, so less oxygen reaches muscles and organs. This is one reason people feel drained. During exercise, the problem worsens. Instead of the vessels relaxing to allow adequate bloodflow, they tighten further. This means that muscles are starved of oxygen and patients experience a crash the day after exercise. In the brain, the same faulty cells let blood flow drop and leak, bringing on brain fog and dizziness. In the gut, they weaken the lining, allowing bits of bacteria to slip into the bloodstream and trigger more inflammation. Because blood vessels reach every corner of the body, even scattered patches of these 'zombie' cells found in the blood vessels can create the mix of symptoms seen in long-Covid and ME/CFS. Immune exhaustion locks in the damage Some parts of the immune system kill senescent cells. They are natural-killer cells, macrophages and complement proteins, which are immune molecules capable of tagging and killing pathogens. But long-Covid and ME/CFS frequently have impaired natural-killer cell function, sluggish macrophages and complement dysfunction. Senescent endothelial cells may also send out a chemical signal to repel immune attack. So the 'zombie cells' actively evade the immune system. This creates a self-sustaining loop of vascular and immune dysfunction, where senescent endothelial cells persist. In a healthy person with an optimally functioning immune system, these senescent endothelial cells will normally be cleared. But there is significant immune dysfunction in ME/CFS and long-Covid, and this may enable the 'zombie cells' to survive and the disease to progress. Where the research goes next There is a registered clinical trial in the US that is investigating senescence in long-Covid. Our consortium is testing new ways to spot signs of ageing in the cells that line our blood vessels. First, we expose healthy endothelial cells in the lab to blood from patients to see whether it pushes the cells into a senescent, or 'zombie,' state. At the same time, we are trialling non-invasive imaging and fluorescent probes that could one day reveal these ageing cells inside the body. In selected cases, tissue biopsies may later confirm what the scans show. Together, these approaches aim to pinpoint how substances circulating in the blood drive cellular ageing and how that, in turn, fuels disease. Our aim is simple: find these ageing endothelial cells in real patients. Pinpointing them will inform the next round of clinical trials and open the door to therapies that target senescent cells directly, offering a route to healthier blood vessels and, ultimately, lighter disease loads.

MyVoice: Views of our readers 28th July 2025
Stampede at Mansa Devi temple is quite shocking It was quite shocking to hear about the stampede at Haridwar's Mansa Devi temple on Sunday that claimed six lives and left many injured. Reportedly, electric current at the base of the temple stairs triggered panic among the devotees, causing them to flee in confusion leading to the stampede. Perched atop the Shivalik Hills at a height of over 500 feet, the Mansa Devi temple is dedicated to Goddess Mansa Devi. Bhagwan Thadani,Mumbai We must draw on Kalam's legacy On this Punya Thithi (July 27) of Dr APJ Abdul Kalam, let us honour his legacy by embracing his vision for a united, innovative India. His dedication to education and youth empowerment inspires us to contribute actively to nation-building. Together, we can soar as envisioned by the 'Missile Man of India' and the 'People's President'. T S Karthik,Chennai Hepatitis: Let's break it down On 'World Hepatitis Day' (July 28), let us look at the chilling facts and figures. Approximately 304 million people worldwide live with chronic hepatitis B or hepatitis C in 2022. Over 2.2 million new infections occur annually, which averages to 6,000 new cases every day. Tragically, 1.3 million succumb to it every year, which means there are 3,500 deaths per day due to hepatitis-related illness. An estimated 40 million Indians live with chronic hepatitis B, and around 12 million have chronic hepatitis C. Bihar, Punjab, Haryana, Madhya Pradesh, Odisha report the highest hepatitis cases in India. Left unchecked, hepatitis B and C may soon claim more lives than HIV, TB and malaria. Although hepatitis B vaccination has been a part of India's Universal Immunisation Programme since 2007, the coverage and awareness - especially beyond childhood - remains inadequate. The theme of World Hepatitis Day-2025 is 'Hepatitis: Let's Break It Down', to emphasise the need to dismantle barriers, such as social, financial, and systemic obstacles, that prevent the elimination of hepatitis and the prevention of liver cancer. On this day, let us all organise awareness programs, share on social media and pledge to create a world free from viral hepatitis infections by following protocols. Dr Burra Madhusudhan Reddy,Karimnagar Bravo OU Engg dept whizkids It is delightful to note that the engineering department of Osmania University has successfully devised a self-guiding semiconductor microchip. This bluetooth-operated frequency synthesiser' made under 'chips to start-up' scheme is said to improve the efficiency of internal machines in smart phones, watches and rockets, among others. This is an appreciable achievement as it is the first indigenous semiconductor chip in India. The enormous talent of young scientists in the country must be utilised and promoted adequately. The children should be extolled to idolise scientists and intellectuals and not actors and cricketers. M Chandrasekhar,Kadapa. Kudos to railways for green energy drive Kudos to Indian railways for achieving another milestone. It made history by successfully testing the first (green) hydrogen powered coach/car at the Integrated Coach Factory in Chennai. This makes for a good initiative as there will be no carbon emissions or pollution issues. Moreover, there are several other benefits by its use, including in promoting eco-friendly transport and being economical even as it swells the profits. It would be a wise move if all types of green energy are heavily patronised and not for just fans and lights. P V P Madhu Nivriti,Secunderabad-61 Govt should come clear on Dhankhar exit This is further to your editorial 'Buzz around Dhankhar resignation not good for NDA government'. No matter if Jagdeep Dhankhar's quit as the country's Vice-President citing health reasons but what is surprising is that it sent people into performative overdrive after self-proclaimed defenders took turns to attack him for 'lowering the dignity' while in office. However, the fact is that he was not a rubber stamp nor a mute spectator. Though Dhankhar is arguably the first high-profile exit from a high constitutional office in recent times, what surprised many is the resignation coming on the first day of the monsoon session of the Parliament. Since, we are left with nothing more than conjecture and speculation on the reasons for his exit, the government should clear the air and prevent an unhealthy controversy over its alleged difference with Dhankhar.
