Pharmaceuticals and Other Emerging Contaminants Force Fish to Work Harder to Survive

Pharmaceuticals and other man-made contaminants are forcing fish that live downstream from a typical sewage treatment plant to work at least 30 per cent harder just to survive, McMaster researchers have found.

New data analysis suggests that people born at the time of the 1957 H2N2 or Asian Flu pandemic were at a higher risk of dying during the 2009 H1N1 Swine Flu pandemic as well as the resurgent H1N1 outbreak in 2013-2014. And it is not the first time this has happened.

DNA Analysis of Ancient Mummy, Thought to Have Smallpox, Points to Hepatitis B Infection Instead

Scientists have sequenced the complete genome of an ancient strain of Hepatitis B, shedding new light on a pathogen that today kills nearly one million people every year. The findings, based on data extracted from the mummified remains of a small child buried in Naples, Italy, confirm the idea that HBV has existed in humans for centuries.

McMaster Researchers Find Genes May ‘Snowball’ Obesity

The researchers looked at 37 genes that are well established as modulating the body mass in 75,230 adults with European ancestry and found the nine with the snowball effect.

There is a more than 50 per cent reduction in the occurrence of headaches with the atraumatic needles, and also more than a 50 per cent reduction in patient readmissions and return to emergency rooms for narcotics or blood patches.

Fish Exposed to Treated Wastewater Have Altered Behaviour: Research

IMG_12122.jpg

A team of researchers from Environment Canada and Climate Change Canada and McMaster University have found that fish living downstream from a wastewater treatment plant showed changes to their normal behaviour—ones that made them vulnerable to predators—when exposed to elevated levels of antidepressant drugs in the water.

The study utilized data from 74 mother-infant pairs in the McMaster pilot cohort called Baby & Mi. Participants came from low-risk populations in Hamilton and Burlington, Ontario. The gut bacteria development of the infants was tested at four points over the first 12 weeks of life, including at three days, 10 days, six weeks and 12 weeks.

McMaster Researchers Uncover Link Between Immune Function and Osteoarthritic Pain and Progression

The study, published in the medical journal Osteoarthritis and Cartilage, found that monocytes, the white blood cells necessary to regulate immune responses, were more activated and pro-inflammatory in women with osteoarthritis, and that elevated inflammation and body mass index were associated with this increased activation.

Workouts to Remember: New Research Suggests High-Intensity Exercise Boosts Memory

The health advantages of high-intensity exercise are widely known but new research from McMaster University points to another major benefit: better memory. The findings could have implications for an aging population which is grappling with the growing problem of catastrophic diseases such as dementia and Alzheimer’s.

Study Finds Asthma and Food Allergies Predictable at Age One

Using data from more than 2,300 children from across Canada participating in the CHILD Study, the researchers evaluated the presence of AD and allergic sensitization at age one. When the children were three years of age, the researchers performed a clinical assessment to determine the presence of asthma, allergic rhinitis, food allergy and AD. The combined effect of AD and allergic sensitization was found to be greater than the sum of their individual effects, both on the risk of asthma and on reported food allergy.
