Recent research, presented at Digestive Disease Week 2019, finds that various types of physical activity including walking and strength exercises are connected to the reduced risk of dying from cirrhosis.
For the study, the researchers prospectively followed 68,449 women from the Nurses’ Health Study and 48,748 men from the Health Professionals Follow-up Study. None of them had liver disease diagnosis at baseline.
Participants of the study provided data on physical activity, which included type and intensity, every two years from 1986 through 2012. These data allowed researchers to examine the link between physical activity and cirrhosis-associated death.
Lead researcher of the study Tracey Simon, MD and instructor of medicine at Harvard Medical School and Massachusetts General Hospital, Boston, says: “Our findings show that both walking and strength training contribute to substantial reductions in risk of cirrhosis-related death, which is significant because we know very little about modifiable risk factors.”
A new study from the University of South Australia in Adelaide aimed to determine how much coffee would increase the risk of developing cardiovascular disease in people with and without the genetic variant.
For the study, the researchers analyzed data from 347,077 people aged from 37 to 73 from UK Biobank. The number of those who had a diagnosis of cardiovascular disease was 8,368.
Study co-author Prof. Elina Hyppönen concludes: “In order to maintain a healthy heart and a healthy blood pressure people must limit their coffees to fewer than six cups a day — based on our data six was the tipping point where caffeine started to negatively affect cardiovascular risk.”
A team of scientists from the National Center for Nanoscience and Technology in Beijing, China, developed a DNA platform able to carry chemotherapy drugs into specific cancer cells as well as silence the cells’ drug-resistant genes.
The team has successfully tested the ability of the DNA platform to selectively deliver RNA transcription templates and the chemotherapy drug doxorubicin in cell cultures and then in mice with multidrug-resistant tumors.
The received results demonstrated that the DNA tool was efficient both at the selective delivery and release of the two items which also led to a highly-selected tumor kill rate.
The authors conclude in their paper: “This tailored DNA nanoplatform, which combines RNAi therapy and chemotherapy, provides a new strategy for the treatment of multidrug-resistant tumors.”
New research from Florida State University suggests that eating cottage cheese before going to bed may boost metabolism and strengthen the muscle and immune system due to the high content of protein.
For the study, a team of researchers checked the effect of eating cottage cheese before bed on 10 women aged between 20 and 30. Each woman ate 30g (1oz) of cottage cheese 30–60min before sleep.
Having analyzed the results of tests, the scientists concluded that women’s bodies were just as efficient after cottage cheese as when they were given a casein shake before bed.
The study author Professor Michael Ormsbee says: “Until now, we presumed whole foods would act similarly to the data on supplemental protein, but we had no real evidence. This is important because it adds to the body of literature that indicates whole foods work just as well as protein supplementation. And it gives people options for pre-sleep nutrition that go beyond powders and shaker bottles.”
A large-scale study by scientists from the Cleveland Clinic in Ohio finds that even large amounts of aerobic exercise still increase the lifespan, especially in older people.
For the study, a team of researchers led by Dr. Wael Jaber who is a cardiologist at the Cleveland Clinic has analyzed the data from 122,007 people who participated in exercise treadmill testing from January 1, 1991, to December 31, 2014. The scientists paid the special attention to the link between aerobic exercises and lifespan.
Having analyzed the received data, the researchers concluded that higher levels of aerobic fitness were associated directly with the lower risk of long-term mortality.
Dr. Wael Jaber explains: “Aerobic fitness is something that most patients can control. And we found in our study there is no limit to how much exercise is too much […] Everyone should be encouraged to achieve and maintain high fitness levels.”
