A new study, published in the journal Gut, suggests that women who drink two or more sugar-sweetened beverages (SSB) per day are twice as likely to develop colorectal cancer before the age of 50.
For their study, a team of researchers performed the analysis of data from 95,464 participants in the Nurses’ Health Study II, an ongoing monitoring study of 116,430 U.S. registered nurses, all women, who were aged 25–42 years when they enrolled in 1989.
The analysis showed that each daily serving of sugar-sweetened beverage peopled consume between the ages of 13 and 18 years may increase the risk of developing early-onset colorectal cancer by 32%.
The authors conclude in their paper that their study “add[s] unique epidemiologic evidence that SSB intake may partly contribute to the rapid increase of CRC in younger adults.”
Recent research, conducted by scientists from McMaster University and Charité – Universitätsmedizin Berlin in Germany, found that bacteria do not colonize the digestive tract before birth – it happens during and after birth.
For their study, a team of researchers examined prenatal stool (meconium) samples taken from 20 babies during breech Cesarean delivery.
Including only breech cesarean deliveries in healthy pregnant women helped to avoid the transmission of bacteria that occurs naturally during vaginal birth.
The first author of the study and a Ph.D. student Katherine Kennedy says: “The key takeaway from our study is we are not colonized before birth. Rather, our relationship with our gut bacteria emerges after birth and during infancy.”
Scientists from the Wageningen University in the Netherlands have trained more than 150 bees to identify COVID-19 cases using their sense of smell.
The scientists managed to train the insects by giving them a sugar-water solution every time they were exposed to the scent of a mink infected with COVID-19. But when the bees were exposed to a non-infected sample, they wouldn’t get a reward. This process is called Pavlovian conditioning.
Such a method of identifying people with COVID-19 is possible because metabolic changes from the coronavirus make an infected person’s bodily fluids smell a bit different than those of a person without the disease.
Holger Volk, a veterinary neurologist, says: “No one is saying they can replace a PCR machine, but they could be very promising.”
A new study, conducted by researchers from the University of Basel, Switzerland, finds that exercise aimed to train motor skills in prematurely born children helps boost their cognitive development even in teenage years.
For the study, the researchers compared a group of 54 very preterm children aged 9 to 13 years with a control group of children of the same age who had been born at term. To test impulse control, the sports scientists conducted a “go/no go” test with the children. After a signal, the study participants had to push a button as quickly as possible. When given a different signal, they were not allowed to push the button.
Lead researcher Dr. Sebastian Ludyga comments on the results of the study: “We conclude from these findings that targeted motor skills training could also reduce cognitive limitations.”
A new study, conducted by scientists from Belgium and Switzerland, finds that ‘exergaming’, a combination of exercise and video games, may improve lower extremity and cognitive functioning, step reaction time, and symptoms of depression in people with dementia.
For their study, researchers used Dividat Senso, an exergame that was developed by Dividat, and recruited 45 participants, aged, on average, 85 years, with severe dementia symptoms from two long-term care facilities in Belgium.
All participants were divided into two groups, one of which performed exercise sessions with the help of Dividat Senso machine for 15 minutes, 3 times a week for 8 weeks. The second group watched music videos, choosing.
The results showed that those who performed exergames had improved gait speed, cognitive function, mobility, balance, and step reaction time. They also demonstrated improvements in leg function and depression symptoms.
A new study, conducted by a team of researchers from the Centre for Addiction and Mental Health (CAMH) and King’s College London in the UK, suggests that the genes, responsible for developing schizophrenia, could prove to be the key to explaining why some cannabis users suffer from psychosis while others don’t develop this condition.
For their study, the scientists analyzed data of 100,000 participant records from the UK Biobank to examine the relationship between genetics, cannabis use, and psychotic experiences.
Psychiatrist Michael Wainberg, one of the researchers, comments on the results of the study: “These results are significant because they’re the first evidence we’ve seen that people genetically prone to psychosis might be disproportionately affected by cannabis.”
