WASHINGTON Dallas Cowboys Vapor Untouchable Jerseys , Dec. 15 (Xinhua) -- The number of clinical trials funded by the U.S. government has fallen substantially, while the number of industry-sponsored trials has increased dramatically since 2006, according to a study published Tuesday that led researchers to call for a discussion on how to best allocate U.S. health research budgets.
"My concern is that independent trials are on the decline and that means we have less high-quality data to inform public health that are not influenced by commercial interests," study leader Stephan Ehrhardt Dallas Cowboys Color Rush Jerseys , an associate professor in the Johns Hopkins Bloomberg School of Public Health, said in a statement.
"When I am doing a government-funded trial comparing two treatments, I start with the assumption that both treatments are equal. I don't have a vested financial interest in the outcome," Ehrhardt said.
"But when I am a drug company testing my new product Randy Gregory Jersey , my objectivity can be compromised by the company's bottom line since it costs me millions of dollars to develop and test my product to get it on the market. It might be difficult for me to be completely objective. The stakes are very high," he said.
In the U.S., the National Institutes of Health (NIH) and the pharmaceutical industry have been major funders of trials.
In general, pharmaceutical companies fund trials that test their own products Rico Gathers Jersey , whereas the NIH's funding strategies are not commercially motivated. Results from NIH-funded trials often provide the basis for prevention and treatment recommendations.
For the study, Ehrhardt and his colleagues searched the NIH-built database, ClinicalTrials.gov, for "interventional study" and then searched by funder type for trials registered between 2006 and 2014.
The number of newly registered industry-sponsored trials increased 43 percent over the time period from 4 Charles Tapper Jersey ,585 in 2006 to 6,550 in 2014. The number of newly registered NIH-funded trials decreased 24 percent over the same period from 1,376 in 2006 to 1,048 in 2014.
Both NIH and industry trials are required to be registered if researchers intend to publish the results.
Ehrhardt said he believes that the decline in NIH-funded studies can be traced to two things. One is the flat NIH funding Joe Looney Jersey , since the 2014 budget was 14 percent less than in 2006, after adjusting for inflation. The other is the greater competition for these limited dollars from other relatively new research areas such as genomic research or personalized medicine studies.
"We need a discussion on how to best allocate our health-related research budgets," he said. "What best informs public health? It's probably clinical trials in large populations, such as testing to see if a reduced-salt diet reduces blood pressure. That study changed the way people eat and helped to reduce hypertension in many people. Industry would never do that. They'd have no interest in a reduced-salt diet. There's no money in that."
The findings were published in the Journal of the American Medical Association.
For a lay man Bo Scarbrough Jersey , cricket is a game of bat and ball. However, the cricket kit comprises of a lot more stuff than just the bat and ball. Cricketers these days use a lot of protective wear apart from the basic clothing. A cricketer?s bag consists of bats, balls, pads Mike White Jersey , gloves, protective guards and clothing. Different equipments may be used by different types of players depending on whether they are a bowler, wicket keeper or a batsman.
They are fielding specialists and they use the normal protective equipment used by the batsmen but they differ in their wicket keeping gloves and pads. Their gloves, unlike those of the batsmen are larger and less padded specifically designed for catching. Wicket keepers also wear inside gloves to reduce friction. Also the wicket keeper?s pads are more slender than the batsmen?s to facilitate free motility.
All cricketers have the basic cricketing equipments in their kits irrespective of the fact that they specialize in batting Dalton Schultz Jersey , bowling or wicket keeping. The various cricketing equipments include:
? Cricket bat: It is a bat made of English willow which has a smooth face and a curved back to provide the required thickness and balance. It has a long handle to help the players play nice shots.
? Leg guards: Leg pads are important as they protect the shin and the knees from damage when batting and wicket keeping. It is a compulsory batting equipment.
? Batting gloves: There are mainly two kinds of gloves, the one worn by the batsmen and the one worn by the wicket keeper. The only difference between the two gloves is that there is a thick padding above the fingers for the batsmen, and for the wicket keeper the gloves are larger in size with a web between the thumb and the forefinger to catch the ball easily.
? Cricket balls: The circumference of a regular cricket ball should be about 9 inches. It is made up of cork which is surrounded in twine and covered by leather, which is then again stitched to form a seam. White balls are used in one day internationals and brown balls are used in test cricket.
? Cricket clothing: For test cricket Dorance Armstrong Jr. Jersey , colored clothing is not preferred and only white is recommended. For one day internationals, every team has a different coloured uniform depending on their choice.
? Helmets: They have become mandatory these days to protect the batsmen and the wicket keeper from damage caused by the fast pace of the ball. Also these helmets act as a protection against the sun. Fielders or bowlers can choose to wear sun hats or cricket caps.
? Spiked shoes: Since cricket is a game which involves running on grass or sometimes bare turfs it is absolutely essential to wear spiked shoes as it increases traction. But some cricketers prefer to wear basic sneakers which provide adequate traction.
Shin guards offer extra protection to the fielders w.
