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.”
For the study, a team of researchers analyzed medical records from 1947 patients from the University of Florida health clinic. They were older than 55 years and matched every AMD case. Also, 5841 patients were included as controls.
The authors of the study conclude in their paper: “We found that metformin, but not other medications, was associated with decreased odds of developing AMD. These findings suggest that metformin itself, and not other medications, has an important protective role.”
Recent research suggests that eating whole-grain rye or wheat influences serotonin levels in plasma and microbiota with certain effects for health such as decreasing the risk of developing type 2 diabetes.
The study was performed by the University of Eastern Finland and the International Agency for Research on Cancer in Lyon, France.
In the course of the study, the researchers investigated how whole grains influence different metabolites in the blood.
The analysis of the received blood samples from people eating different products showed that people who had plenty of whole grains in their diet had significantly lower serotonin levels in plasma than those who ate a low-fiber diet.
Study co-author Kati Hanhineva, Ph.D., explains: “Whole grain, on the other hand, is known to reduce the risk of diabetes, and on the basis of these new results, the effect could at least partly be due to a decrease in serotonin levels.”
A large US study suggests that appendix removal raises the risk of developing Parkinson’s disease later in life.
For the research, a team of scientists took data from a giant database of US electronic health records. These data were from 488,190 patients who had their appendixes removed. Later, 4,470 people of this number were diagnosed with Parkinson disease.
The profound analysis of medical records showed that people with the appendix removed are at three times higher risk of being diagnosed with Parkinson’s disease.
Lead researcher Mohammed Z. Sheriff from Case Western Reserve University comments: “This research shows a clear relationship between the appendix, or appendix removal, and Parkinson’s disease, but it is only an association. Additional research is needed to confirm this connection and to better understand the mechanisms involved.”
A new study from the University of Michigan in Ann Arbor finds that physical exercise may effectively treat depression in men but not in women.
For the study, the researchers examined the exercise and sleep patterns of 1,100 people studying at Beijing University in China. The analysis of the received data showed that 43% if female participants had depressive symptoms compared with 37% of male participants.
Researchers say that more studies needed with more people from other countries to check if the results can be applied globally.
Dr. Michael Craig Miller, assistant professor of psychiatry at Harvard Medical School explained in earlier study: “In people who are depressed, neuroscientists have noticed that the hippocampus in the brain — the region that helps regulate mood — is smaller. Exercise supports nerve cell growth in the hippocampus, improving nerve cell connections, which helps relieve depression.”
