All of the runners, who were in their early to mid-20s, were in exceptional shape, with aerobic capacities at or above the 98th percentile for men of their age. Then in 2012, he mentioned this trove of unpublished data to his colleague Sarah Everman, an assistant professor of kinesiology at the university. At the lab, the researchers ran the men through the same tests as before and asked about exercise routines.
Although vitamin B supplements claim to increase energy and improve metabolism, a new study finds a relationship between high doses of certain B vitamins and an increased risk of lung cancer in male smokers. B vitamins - B-6, B-9 (folate), and B-12 - are commonly thought to reduce cancer risk, among other benefits. Over recent years, a number of studies have looked for links between lung cancer and B vitamins.
People with tinnitus may experience a worsening of the condition if they are being treated with selective-serotonin reuptake inhibitors, a common class of antidepressants. Tinnitus is the intermittent or constant sensation of hearing sounds when no such sounds are present. According to the American Tinnitus Association, more than 45 million people in the United States are affected by tinnitus. Previous studies have suggested that people with tinnitus are at increased risk of depression, compared with people without the condition.
Ever since I can remember, I've been told to strive for balance. Trying to be balanced - devoting equal proportions of time and energy to other areas of my life - would have detracted from the formative experiences. A telltale sign of these optimal experiences, of being in the zone, is that the outside world disappears. In such a state, flow and balance are irreconcilable. Compared to flow, balance seems, for lack of a better term, boring.
The findings add to the urgency to find reliable ways to detect colorectal cancer early in young people. One organization, the American College of Gastroenterology, recommends that African-Americans start routine screening at 45 because they are at higher risk for colorectal cancer than whites. Any proposal to expand universal screening, however, will be both controversial and potentially costly, since the vast majority of colorectal cancer deaths still occur among older adults.
For those who like their coffee sweetened, having it without sugar is easier said than done. In a new study, Richie Lenne and Traci Mann of the University of Minnesota in Minneapolis tested two interventions to help coffee drinkers reduce their sugar consumption. In one group, people gradually decreased the amount of sugar they were adding to their coffee, by a little bit per day. Helping people reduce their sugar intake is an important goal for promoting health, Lenne said.
India has granted Pfizer Inc a patent for its powerful pneumonia vaccine Prevenar 13, in a blow to some health groups that said this would put the treatment out of reach of thousands in poorer nations. The decision by India's patent office bars other companies from making cheaper copies of the vaccine and allows Pfizer to exclusively sell it in India until 2026. It also comes at a time of ongoing US pressure on India to tighten its patent laws.
Seven major drinks companies including Coca-Cola and PepsiCo will limit the sugar content of drinks they sell in Singapore, as part of the city-state's campaign to fight diabetes. Globally, beverage firms have been reworking recipes, racing to cut sugar and introduced more options to cater to increasingly health-conscious consumers. It said it had been reducing sugar and calories across many of its brands, and offering more new drinks with low sugar content or no added sugar.
Eye doctors who had braced themselves for at least a few patients after a dazzling solar eclipse swept the United States cautiously exhaled on Tuesday, with some hospitals reporting zero cases of damaged vision so far. At Nashville's Vanderbilt University Medical Center, however, seven people were scheduled to see doctors with concerns from viewing the eclipse, Dr Shriji Patel said. We have opened extra clinics over the next three days, and I'm expecting them to be full, he said.
J&J, which denies any link between talc and cancer, said in a statement it would appeal Monday's verdict but declined further comment. This has very much been about forum shopping, Howard Erichson, a professor at Fordham School of Law, said about the talc trials. The fact that there has been a big verdict in California is definitely interesting. Legal experts said the verdict in the California case, in which venue was not an issue, could shift the focus back to the evidence.
People who decide to tackle their cancer using only unconventional methods are likely to die sooner than patients who opt for conventional treatments, according to a new study. Little is known about patients who choose only unconventional methods to address their cancer, Johnson and colleagues write in the Journal of the National Cancer Institute, online August 10. The researchers had data on 280 people who tried only unproven methods administered by nonmedical personnel.
Consistent childcare arrangements - even complicated ones - didn't seem to affect young children's nighttime sleep. The questions covered childcare experiences such as time spent in childcare centers, time with relatives and time with non-relatives, as well as use of multiple childcare settings. Among children who attended childcare in both infancy and toddlerhood, sleep did not appear to be affected by childcare arrangements - as long as the same childcare configuration was maintained.
The study examined county-level data on voting patterns from the 2008 and 2016 presidential elections and on life expectancy for people born from 1980 to 2014. In counties with below-average gains in life expectancy or declines, a majority of voters chose Trump, the Republican nominee. Overall, Republicans lost 67,000 votes from 2008 to 2016 in counties with above-average gains in life expectancy but gained 3.1 million votes in counties with below-average life expectancy trends.
Researchers in Tennessee have found that the sugars in human breast milk have the potential to protect against group B strep. Human milk contains sugars that may protect against group B strep, which is a leading cause of severe infection in newborn babies. Most babies do not become infected, the Vanderbilt University team wondered if human milk might also contain some compounds that specifically protect against group B strep.
The findings could pave the way for a drug that could one day help humans to live better for longer. The compound occurs in some flowers, such as jasmine and orange blossom, but it can also be found in fecal matter. Indoles are also produced in our gut by many kinds of bacteria that break down tryptophan, which is an essential amino acid. The researchers also carried out experiments in mice, destroying their gut flora by administering them antibiotics.
A cancer-related skin rash is caused by a cancerous or precancerous condition that produces abnormal changes in the skin. Skin cancer rashes may take on a similar scaly appearance, and the skin may also crack or bleed. Skin cancer rashes are more likely to contain oddly colored patches of skin, not just red. The rashes caused by skin cancer will typically last much longer than other skin conditions.
Raccoon eyes may be used to describe large dark rings around the eyes. Medically known as periorbital ecchymosis, this condition describes bruising and discoloration around a person's eyes that resemble the dark circles around a raccoon's eyes. Raccoon eyes are usually a sign of a serious condition that should be diagnosed and treated immediately. Raccoon eyes are also likely to show up if the thin bones surrounding the eyes break.
Depending on the area where tissue damage occurs, nosebleeds are categorized either as anterior or front or as posterior or back. A posterior nosebleed occurs when the artery branches that supply blood to the nose become damaged. Inflatable balloon catheters work well to stop blood flow for posterior bleeding sources. A posterior nosebleed is more concerning than an anterior one and often requires medical treatment. Most people will recover from posterior nosebleed without any complications or long-term problems.
In a search for new treatments for type 2 diabetes, researchers have discovered that implanting polymer sponges into fat tissue might offer a way forward. Diabetes is a long-lasting disease that develops when the body either does not make enough insulin or cannot use insulin effectively. Insulin is a hormone that helps cells to take up sugar from the blood so they can use it for energy.
Researchers suggest that caffeine could reduce the impact of poor sleep on postoperative pain. Previous research has suggested that insufficient sleep before and after a surgical procedure may increase postoperative pain severity. While the relationship between sleep and pain is well known, its underlying mechanisms remain unclear, notes Dr Vanini. Furthermore, the team investigated whether caffeine - a known stimulant - might help to reduce postoperative pain triggered by lack of sleep.
