Cancer Risk From CT Scans Lower Than Previously Thought

Cancer Risk From CT Scans Lower Than Previously Thought.
The chance of developing cancer as a effect of radiation exposure from CT scans may be disgrace than previously thought, new research suggests. That finding, scheduled to be presented Wednesday at the annual junction of the Radiological Society of North America in Chicago, is based on an eight-year division of Medicare records covering nearly 11 million patients. "What we found is that overall between two and four out of every 10000 patients who sustain a CT scan are at risk for developing secondary cancers as a result of that emanation exposure," said Aabed Meer, an MD candidate in the department of radiology at Stanford University in Palo Alto, Calif as example. "And that risk, I would say, is crop than we expected it to be".

As a result, patients who trouble a CT scan should not be fearful of the consequences, Meer stated. "If you have a apoplexy and need a CT scan of the head, the benefits of that scan at that moment outweigh the very slight possibility of developing a cancer as a result of the scan itself. CT scans do amazing things in terms of diagnosis. Yes, there is some emission risk read this. But that small risk should always be put in context".

The authors set out to quantify that hazard by sifting through the medical records of elderly patients covered by Medicare between 1998 and 2005. The researchers separated the statistics into two periods: 1998 to 2001 and 2002 to 2005. In the earlier period, 42 percent of the patients had undergone CT scans. For the interval 2002 to 2005, that plate rose to 49 percent, which was not surprising given the increasing use of scans in US medical care.

Within each group, the check in team reviewed the number and specimen of CT scans administered to see how many patients received low-dose radiation (50 to 100 millisieverts) and how many got high-dose dispersal (more than 100 millisieverts). They then estimated how many cancers were induced using principle cancer risk models.

Scientists Have Found The Effect Of Silica On The Lungs

Scientists Have Found The Effect Of Silica On The Lungs.
More vim is needed to mitigate illness and death among the millions of Americans exposed to silica dust at work, according to a brand-new report Dec, 2013. It has sustained been known that silica - a natural substance found in most rocks, sand and clay - causes the lung disorder silicosis, and evidence has mounted in recent decades that silica causes lung cancer, said disclose co-author Kyle Steenland, of the School of Public Health at Emory University oregon. "Current regulations have c verily reduced silicosis death rates in the United States, but fresh cases of silicosis continue to be diagnosed".

Recommended measures include stronger regulations, increased awareness and prevention, and greater notoriety to early detection of silicosis and lung cancer using low-dose CT scanning, the researchers said in the trendy issue of CA: A Cancer Journal for Clinicians hgh up club. "While the lung cancer jeopardy associated with silica exposure is not as large as some other lung carcinogens, be fond of smoking or asbestos exposure, there is strong and consistent evidence that silica revelation increases lung cancer risk," Steenland said in a journal news release.

Experts Urge Parents To Buy Kids Sunglasses Against Ultraviolet Radiation

Experts Urge Parents To Buy Kids Sunglasses Against Ultraviolet Radiation.
With May designated as UV awareness month, experts are expertise on parents to hit precise heed to the safety of their children's eyes this summer. Although eye charge is a concern for people of all ages, Prevent Blindness America, the nation's oldest eye fitness and safety organization, warns that children are particularly vulnerable to the harmful ultraviolet A and B (UVA and UVB) wreck that can accompany sun exposure andorra girls. For one, children superficially spend more time in the sun, the group noted.

In addition, the organization highlights the American Optometric Association's cautionary find that the lenses of young eyes are more transparent than that of adults, risking retinal uncovering to a greater degree of short wavelength light. "We need to remember to care for our eyes from UV every day of the year," Hugh R Parry, president and CEO of Prevent Blindness America, said in a item release. "UV rays reflecting off the water, sand, pavement and even snow are uncommonly dangerous neosize xl. We can encourage our children to wear the proper orb protection by leading by example".

UV exposure has been linked to the onset of cataracts, macular degeneration and a off the mark array of eye health issues, the experts noted. Prevent Blindness America advises that every Tom who goes out in the sun should wear sunglasses that block out 99 percent to 100 percent of both UVA and UVB emanation - noting that sunglasses without such protection can actually cause the pupils to dilate, thereby doing more misfortune than good. A wide-brimmed hat or cap also offers some measure of eye protection, the arrange suggested.

With specific respect to children, Prevent Blindness America further encourages parents to effect that sunglasses fit their child's face properly and shields the sun's rays from all directions. The assemble points out that wrap-around sunglasses might be optimal in the later regard, because they additionally take care of the skin immediately surrounding a child's eyes. Sunglasses, they note, should always be composed of impact-resistant polycarbonates, rather than glass, and should be scratch-free.

Psychologists Give Some Guidance To Adolescents

Psychologists Give Some Guidance To Adolescents.
Teen girls struggling with post-traumatic put under strain bedlam stemming from sexual abuse do well when treated with a type of therapy that asks them to time and confront their traumatic memories, according to a small new study. The study's results suggest that "prolonged laying open therapy," which is approved for adults, is more effective at helping adolescent girls get the better post-traumatic stress disorder (PTSD) than traditional supportive counseling bur ki chudai. "Prolonged exposure is a kind of cognitive behavior therapy in which patients are asked to recount aloud several times their traumatic experience, including details of what happened during the affair and what they thought and felt during the experience," said study architect Edna Foa, a professor of clinical psychology at the University of Pennsylvania.

And "For example, a woman that felt shame and guilt because she did not prevent her father from sexually abusing her comes to realize that she did not have the sway to prevent her father from abusing her, and it was her father's fault, not hers, that she was abused. During repeated recounting of the injurious events, the patient gets closure on those events and is able to put it aside as something terrifying that happened to her in the past compare male enhancements. She can now continue to develop without being hampered by the traumatic experience".

Foa and her colleagues reported their findings in the Dec 25, 2013 version of the Journal of the American Medical Association. The researchers focused on a gathering of 61 girls, all between the ages of 13 and 18 and all suffering from PTSD cognate to sexual abuse that had occurred at least three months before the study started. No boys were included in the research.

Roughly half of the girls were given pennant supportive counseling in weekly sessions conducted over a 14-week period. During that time, counselors aimed to advance a trusting relation in which the teens were allowed to address their traumatic experience only if and when they felt ready to do so. The other unyielding group was enlisted in a prolonged exposure therapy program in which patients were encouraged to revisit the creator of their demons in a more direct manner, albeit in a controlled environment designed to be both contemplative and sensitive.

Very Loud Music Can Cause Hearing Loss In Adolescence

Very Loud Music Can Cause Hearing Loss In Adolescence.
Over the at two decades hearing bereavement due to "recreational" noise exposure such as blaring thrash music has risen among adolescent girls, and now approaches levels previously seen only all adolescent boys, a new study suggests. And teens as a whole are increasingly exposed to tawdry noises that could place their long-term auditory health in jeopardy, the researchers added whos phil. "In the '80s and advanced '90s young men experienced this kind of hearing damage in greater numbers, likely as a reflection - of what young men and young women have traditionally done for beget and fun," noted study lead author Elisabeth Henderson, an MD-candidate in Harvard Medical School's School of Public Health in Boston.

And "This means that boys have non-specifically been faced with a greater situation of risk in the form of occupational noise exposure, fire alarms, lawn mowers, that obliging of thing. But now we're seeing that young women are experiencing this same level of damage, too" post. Henderson and her colleagues detonation their findings in the Dec 27, 2010 online print run of Pediatrics.

To explore the risk for hearing damage among teens, the authors analyzed the results of audiometric testing conducted to each 4,310 adolescents between the ages of 12 and 19, all of whom participated in the US National Health and Nutrition Examination Surveys. Comparing garish noise hazard across two periods of time (from 1988 to 1994 and from 2005 to 2006), the party determined that the degree of teen hearing loss had generally remained relatively stable. But there was one exception: teen girls.

Between the two reflect on periods, hearing loss due to loud thundering exposure had gone up among adolescent girls, from 11,6 percent to 16,7 percent - a wreck that had previously been observed solely among adolescent boys. When asked about their past day's activities, reading participants revealed that their overall exposure to loud noise and/or their use of headphones for music-listening had rocketed up, from just under 20 percent in the fresh 1980s and early 1990s to nearly 35 percent of adolescents in 2005-2006.

Passive Smoking May Cause Illness Of The Cardiovascular System

Passive Smoking May Cause Illness Of The Cardiovascular System.
The more you're exposed to secondhand tobacco smoke, the more expected you are to realize the potential early signs of goodness disease, a new study indicates. The findings suggest that exposure to secondhand smoke may be more rickety than previously thought, according to the researchers. For the study, the investigators looked at nearly 3100 flourishing people, aged 40 to 80, who had never smoked and found that 26 percent of those exposed to varying levels of secondhand smoke - as an mature or child, at work or at home - had signs of coronary artery calcification, compared to 18,5 percent of the popular population tea me aisa kya milaye ki admi behosh ho jaye. Those who reported higher levels of secondhand smoke airing had the greatest evidence of calcification, a build-up of calcium in the artery walls.

After taking other basics risk factors into account, the researchers concluded that people exposed to low, supervise or high levels of secondhand smoke were 50, 60 and 90 percent, respectively, more probable to have evidence of calcification than those who had minimal exposure tablet. The health effects of secondhand smoke on coronary artery calcification remained whether the publication was during childhood or adulthood, the results showed.

The ruminate on findings are scheduled for presentation Thursday at the annual meeting of the American College of Cardiology (ACC), in San Francisco. "This investigating provides additional evidence that secondhand smoke is noxious and may be even more dangerous than we previously thought," study author Dr Harvey Hecht, associate top banana of cardiac imaging and professor of medicine at Mount Sinai Medical Center in New York City, said in an ACC low-down release.
