Sperm freezing is becoming an essential option for men today. It is especially important for those about to undergo cancer treatment, which can harm fertility, or for men who wish to plan fatherhood later in life. Experts strongly advise men in such situations to consult a fertility specialist and consider freezing their sperm. Doing so preserves the possibility of having biological children in the future. Currently, a large number of men are suffering from various cancers such as testicular cancer, prostate cancer, blood cancers (like lymphoma or leukaemia), oral cancer, and lung cancer. “Many cancer treatments, such as chemotherapy, radiation therapy, and surgery, may impact sperm production or affect reproductive organs. But there is no need to panic, as this may not happen in all pati...

Japanese researchers have identified two distinct stem cell lineages that drive tooth root and alveolar bone formation, offering key insights for future regenerative dental therapies.  The team from the Institute of Science Tokyo, used genetically modified mice and lineage-tracing techniques to shed light on the cell signaling mechanisms guiding differentiation in stem cells in the developing teeth. "Our findings provide a mechanistic framework for tooth root formation and pave the way for innovative stem-cell-based regenerative therapies for dental pulp, periodontal tissues, and bone," said Mizuki Nagata, Assistant Professor at the Institute`s Department of Periodontology. The ability to regenerate lost teeth and their surrounding bones is considered a holy grail in the field of dentist...

Higher levels of air pollution may not only harm your lungs but also worsen health for people with obstructive sleep apnea (OSA), according to a multi-national study, that strengthened the connection between environmental health and sleep medicine.  While OSA is a common condition, many people do not realise they have it. People with OSA often snore loudly, their breathing starts and stops during the night, and they may wake up several times. The study, presented at the European Respiratory Society (ERS) Congress in Amsterdam, the Netherlands, revealed that, overall, for every one unit increase in PM10 -- tiny particles, 10 micrometers or smaller, released into the air by vehicle exhausts and industrial processes -- there was a modest but measurable increase in the patients` apnoea hypop...

A common gene variant may be delaying diagnoses of type 2 diabetes in millions of men worldwide, and increasing their risk of serious complications, according to a study.  G6PD deficiency is a genetic condition that affects more than 400 million people worldwide, and is especially prevalent among those with African, Asian, Middle Eastern, and Mediterranean backgrounds. It is more common in men and usually goes undetected because it rarely causes symptoms. The World Health Organization (WHO) recommends routine screening for G6PD deficiency in populations where it is common, but it is not widely implemented in many other countries. Researchers from the University of Exeter, in collaboration with Queen Mary University of London (QMUL), found that men with G6PD deficiency are, on average, d...

Heart attack, stroke, or heart failure come with warning signs in 99 per cent cases, according to a large study that refuted the notion that these devastating events often strike people without warning signs.  The study led by Northwestern Medicine, US, and Yonsei University in South Korea, showed people with these deadly cardiovascular diseases -- which remain the leading cause of death worldwide -- had at least one risk factor above an optimal level beforehand. "We think the study shows very convincingly that exposure to one or more nonoptimal risk factors before these cardiovascular outcomes is nearly 100 per cent," said senior author Dr. Philip Greenland, professor of cardiology at Northwestern University Feinberg School of Medicine. "The goal now is to work harder on finding ways t...

A reinfection with the SARS-CoV-2, the virus behind Covid-19 disease, doubled the risk of developing long Covid among children, according to a large study published in the journal The Lancet Infectious Diseases.  The findings involving over 460,000 children and adolescents across 40 paediatric hospitals in the US found that after the first Covid infection, about 904 children per million developed long Covid within six months. Following a reinfection, this number more than doubled to approximately 1,884 children per million. The kids were more likely to suffer from a wide range of rare but persistent and sometimes serious conditions, including heart inflammation (myocarditis), blood clots, kidney injury, cognitive difficulties, fatigue, and respiratory problems. “These findings add to p...

The rapidly changing eating habits with high intake of carbohydrates and saturated fat, with low protein levels, are behind the dramatic increase in diabetes and obesity cases among Indians, according to the latest evidence generated from the Indian Council of Medical Research-India Diabetes (ICMR-INDIAB) study on Tuesday.  The study, published in the journal Nature Medicine, showed that most Indians get a staggering 62 per cent of their calories from carbohydrates -- one of the highest in the world. Much of this comes from low-quality sources like white rice, milled whole grains, and added sugar -- associated with increased metabolic risk (diabetes, prediabetes, and obesity). White rice dominates diets in the South, East, and Northeast, while wheat is more common in the North and Centr...

Skincare isn`t a one-size-fits-all journey, and as the seasons change, so should your routine. Navigating the shift from the humid monsoon season to the drier post-monsoon months can be challenging for your skin.  This transitional period often brings a frustrating mix of lingering oiliness, stubborn breakouts, and new concerns like dehydration and sensitivity.

A newly developed blood test may aid in predicting the risk of developing severe liver disease within 10 years, according to a study.  The study, by researchers from the Karolinska Institutet in Sweden, showed that the simple blood analysis, if applied in primary care, may accelerate the detection of cirrhosis and cancer of the liver. "These are diseases that are growing increasingly common and that have a poor prognosis if detected late," said Rickard Strandberg, affiliated researcher at the Institutet`s Department of Medicine, who developed the test. "Our method can predict the risk of severe liver disease within 10 years and is based on three simple routine blood tests," Strandberg added. For the study, published in the journal The BMJ, the researchers evaluated how well the method ...

Adopting healthy lifestyles can help significantly reduce risk of heart disease, said Union Health Minister JP Nadda on Monday on World Heart Day.  World Heart Day is observed every year on September 29 to raise awareness about various heart diseases and the importance of early detection. “World Heart Day highlights the importance of cardiovascular health and encourages proactive measures to prevent heart-related illnesses. It provides a vital platform to spread awareness about maintaining a strong and healthy heart through balanced nutrition, regular exercise, and stress management,” Nadda said in a post on social media platform X. “By adopting healthy lifestyles, individuals can significantly reduce the risk of heart disease and improve overall well-being. Observing this day inspires ...
