Pancreatic Cancer: Cannabis Compound May Boost Survival

While the current study only looked at the effect of CBD in mice, clinical trials in humans are needed to confirm whether or not CBD improves survival rates of pancreatic cancer patients

A naturally occurring constituent of medicinal cannabis along with chemotherapy could increase the survival rate by three times among mice with pancreatic cancer, according to a new study.

According to the researchers, the cannabinoid named Cannabidiol (CBD) does not cause psychoactive effects and has been already cleared for use at the clinics.

“This is a remarkable result. We found that mice with pancreatic cancer survived nearly three times longer if a constituent of medicinal cannabis was added to their chemotherapy treatment,” said lead author Marco Falasca from Queen Mary University of London in Britain.

“Cannabidiol is already approved for use in clinics, which means we can quickly go on to test this in human clinical trials. If we can reproduce these effects in humans, cannabidiol could be in use in cancer clinics almost immediately, compared to having to wait for authorities to approve a new drug,” he added.

For the study, published in the journal Oncogene, the team tested the impact of the cannabidiol on the use of the commonly used chemotherapy medication Gemcitabine as a treatment for pancreatic cancer in mice.

“Given the five-year survival rate for people with pancreatic cancer is less than seven per cent, the discovery of new treatments and therapeutic strategies is urgently needed,” Falasca noted.

The team explained that CBD is also known to improve the side effects of chemotherapy, including nausea, diarrhoea, vomiting, meaning it could also improve the quality of life of patients undergoing chemotherapy.

While the current study only looked at the effect of CBD in mice, clinical trials in humans are needed to confirm whether or not CBD improves survival rates of pancreatic cancer patients, the researchers said. (IANS)

World’s Smallest Wearable Can Help in Preventing Skin Cancer

It also demonstrated the ability to measure white light exposure for seasonal depression, a mood disorder characterised by depression that occurs at the same time every year

Scientists have developed the world’s smallest wearable, battery-free device that can warn people of overexposure to ultraviolet rays (UV) — a leading factor for developing skin cancer.

Currently, people do not know how much UV light they are actually getting. The rugged and waterproof device interacts wirelessly with the phone and helps maintain an awareness and for skin cancer survivors.

Smaller than an M&M (colourful button-shaped chocolates) and thinner than a credit card, the device can optimise treatment of neonatal jaundice, skin diseases, seasonal affective disorder and reduce risk of sunburns and skin cancer.

Users can glue the device on to their hats, clip it to sunglasses or stick it on their nail and can simultaneously record up to three separate wavelengths of light.

It is always on yet never needs to be recharged.

“There is a critical need for technologies that can accurately measure and promote safe UV exposure at a personalised level in natural environments,” said Steve Xu, from Northwestern University in the US.

“We hope people with information about their UV exposure will develop healthier habits when out in the sun,” said Xu.

There are no switches or interfaces to wear out, and it is completely sealed in a thin layer of transparent plastic, the researchers stated, in the paper published in the journal Science Translational Medicine.

Participants who mounted device on themselves recorded multiple forms of light exposure during outdoor activities, even in the water.

The findings showed that it monitored therapeutic UV light in clinical phototherapy booths for psoriasis and atopic dermatitis (immune diseases) as well as blue light phototherapy for newborns with jaundice in the neonatal intensive care unit.

It also demonstrated the ability to measure white light exposure for seasonal depression, a mood disorder characterised by depression that occurs at the same time every year. (IANS)
