Doctors of a private hospital in Kolkata successfully implant a pacemaker in a 102-year-old woman and discharged her from the facility within two days, one of the physicians said. Implanting a pacemaker may be a common procedure but performing the surgery in the heart of a 102-year-old woman is rare, he said. Dr Smriti Kana Roy, a gynaecologist who used to treat Saint Teresa and other nuns of the Missionaries of Charity, underwent the operation on March 15. Roy, a Fellow of the Royal College of Obstetricians and Gynecologists, had complained of dizziness when doctors found an irregular heartbeat and prescribed the implant, her younger daughter Julie Basu told PTI from the US on Tuesday. "It was an amazing experience. She has no comorbidities. But her heart rate had decreased and her ha...

NASA astronauts Sunita Williams and Butch Wilmore are all set to return to Earth after spending nine months aboard the International Space Station (ISS) for a mission that was supposed to last just eight days. Spending a considerable amount of time in space can pose several health risks, some of which were well-documented as the two astronauts navigated these challenges. Bone and muscle deterioration, radiation exposure, vision impairment —these are just a few of the challenges space travellers face on long-duration missions, even before considering the psychological toll of isolation. In a previous interaction with mid-day.com, Dr Atul Narayankar, Consultant Medical Oncologist, Wockhardt Hospitals, Mira Road, had highlighted how different elements in space can affect health, saying, “W...

A team of doctors in Mumbai successfully removed a cricket ball-sized adrenal tumour, known as ganglioneuroma, from the stomach of a six-year-old boy hailing from Raipur. The patient, Kush Agrawal, who was experiencing excruciating stomach pain, travelled over 1,000 kilometres with his parents to get treatment at a Mumbai hospital. According to the medical team, a tumour, which was suspected to be cancerous, was found in the right adrenal gland, which is located on top of the kidneys and is responsible for producing hormones that regulate functions such as metabolism, blood pressure and the body`s response to stress. They performed a ‘Positron Emission Tomography’ (PET) scan, and it revealed that the tumour had not spread to any other areas. Final histopathological diagnosis revealed it...

The `13th Gut Microbiota for Health World Summit` in Washington, DC, over the weekend revealed how cutting-edge research on gut microbiome science is being applied to clinical practice.  The summit showcased the latest microbiome research on coronavirus, plant and dairy-based protein, as well as probiotics. A novel study found that the gut microbiome in children is altered post-COVID-19 infection, much like it is in adults. Researchers found a significant decrease in beneficial bacteria, like Lacticaseibacillus and Bifidobacterium, in children who had COVID-19 compared to those who didn’t. These bacteria help reduce inflammation and support gut health. Children with lingering symptoms also showed different types of bacteria, in addition to elevated markers of inflammation and decreased...

Australian researchers have identified a surprising mechanism focusing on telomeres -- protective caps at the ends of chromosomes -- that can help cells defend against cancer. Telomeres are known to play a key role in ageing and cancer prevention. However, with age, these structures naturally shorten, signaling ageing cells to stop dividing -- a crucial safeguard against cancer, according to the study by Sydney-based Children`s Medical Research Institute (CMRI) on Monday, Xinhua news agency reported. "Our data shows telomeres are much more active. They can acutely respond to stress and actively open up to turn on a cellular response that looks like ageing. They do this to avoid cancer," said Tony Cesare of the Genome Integrity Unit at CMRI. Cesare and his team worked with their collabo...

Scientists at Osaka University in Japan have devised a new AI model to estimate a person’s biological age — a measure of how well their body has aged, rather than just counting the years since birth.  Using just five drops of blood, this new method analyses 22 key steroids and their interactions to provide a more precise health assessment.  The team’s breakthrough study, published in Science Advances, offers a potential step forward in personalised health management, allowing for earlier detection of age-related health risks and tailored interventions. “Our bodies rely on hormones to maintain homeostasis, so we thought, why not use these as key indicators of aging?” said Dr Qiuyi Wang, co-first author of the study.  To test this idea, the research team focused on steroid hormones, whic...

The new study conducted among urban Indian corporate employees, has found that vitamin B12 deficiency, crucial for neurological function and energy metabolism, was significantly higher among men, with 57.16 per cent showing insufficient or deficient levels. Meanwhile, 49.9 per cent of women also exhibited deficiencies, emphasising the importance of dietary adjustments and supplementation for overall well-being. The study was released earlier this week by Indian digital healthcare company MediBuddy highlighting nutrient deficiencies among Indian corporate professionals aged 40–50. It analysed data from around 4,400 individuals (3,338 men and 1,059 women) in the age group, brings to the fore the urgent need for targeted health interventions and preventive care strategies, particularly for m...

Trying to lose weight? A new study claims replacing animal products with plant-based foods like soy milk and vegan meat that are ultra-processed, can lead to significant weight loss.  The research by the Physicians Committee for Responsible Medicine looked at the role of plant-based processed foods in weight loss. High-processed foods -- rich in sugar, salt, and fat -- are known to be unhealthy and contribute to weight gain, obesity, and a host of diseases. “Our research shows that choosing a bagel instead of bacon for breakfast or a veggie burger instead of a hamburger for dinner is the best option if you are looking to lose weight,” said Hana Kahleova, director of clinical research for the Physicians Committee for Responsible Medicine. “Filling your plate with plant-based foods -- ev...

The quality of diet and waist-to-hip ratio in midlife are associated with brain connectivity and cognitive performance in later life, according to a study. Researchers from Oxford University and University College London in the UK found that people in midlife engaging in healthy eating had an increased hippocampal functional connectivity to the occipital lobe and cerebellum; as well as a better white matter. These improved working memory, executive function, and overall cognitive performance in middle-aged adults. On the other hand, those with higher waist-to-hip ratio in midlife had a widespread decrease in white matter integrity, leading to implications in memory and executive function. Reduced fractional anisotropy in these regions was linked to poorer cognitive performance. “Healt...

Bones form an integral support system for the body, providing structure, protecting essential organs and facilitating movement. With an increase in age generally comes a decrease in bone density. Hence, it becomes important to prioritise and protect your bone health, especially after the age of 30. There are two basic pillars for ensuring bone health – nutrition and exercise. Nutrition for maintaining bone health after 30 It is important to focus on nutrition when it comes to maintaining bone health. One has to have a balanced diet, which contains ample proteins. Calcium is an important nutrient that strengthens bones. “Calcium is generally found in dairy products and non-vegetarian food. However, vegetarians and vegans can opt for calcium supplement if required, as per doctor’s advice...
