CDC Chlamydia 2008 ASHA Std Background Information

shared by Daphne Emrick on 01 Jul 10 - Cached
  • Chlamydia is the most frequently reported bacterial sexually transmitted disease in the United States. In 2008, 1,210,523 chlamydial infections were reported to CDC from 50 states and the District of Columbia. Under-reporting is substantial because most people with chlamydia are not aware of their infections and do not seek testing. Also, testing is not often done if patients are treated for their symptoms. An estimated 2,291,000 non-institutionalized U.S. civilians ages 14-39 are infected with C. trachomatis  based on the U.S. National Health and Nutrition Examination Survey.  Women are frequently re-infected if their sex partners are not tre
  • Chlamydia is known as a "silent" disease because the majority of infected people have no symptoms. If symptoms do occur, they usually appear within 1 to 3 weeks after exposure.
  • To help prevent the serious consequences of chlamydia, screening at least annually for chlamydia is recommended for all sexually active women age 25 years and younger. An annual screening test also is recommended for older women with risk factors for chlamydia (a new sex partner or multiple sex partners). All pregnant women should have a screening test for chlamydia.

teen health ears music decibels

  • The amount of energy in the noise and the damage it can do to your hearing increases very rapidly as it gets louder. In fact, noise energy doubles for every 3 decibels (3dB) increase in the loudness of the sound - and 3dB is such a small increase in loudness that you probably wouldn't even notice it.
  • What sort of noise causes the harm? For young people in particular, the most dangerous noise is amplified music, for example in gigs and clubs. Headphones, car stereos and mobile phones are also having a bad effect on the hearing of young people.
  • Research shows that 25% of people listen to headphones at a level that will cause hearing damage. Follow the 60/60 rule - don't have your player above 60% of the maximum volume, and don't listen to it for more than 60 minutes at a time.

  • One study suggests that listening to headphones at 80% for 90 minutes a day can lead to hearing loss. The authors say that this can take years for the damage to show up, so young people might not notice a loss of hearing until they are in their late 20s. At 100% for only five minutes you could do damage.
  • dulled hearing difficulty in understanding speech feeling full inside your ears ringing or high-pitched noise in your ears
  • In night clubs - where much of the damage is done - do not stay long, don't go too often and keep well away from the loudspeakers - or go somewhere else where the music is not so loud.

Teeth Science Death Data Forensic Bomb Curve

shared by Daphne Emrick on 20 Jul 10 - Cached
  • Livermore researcher Bruce Buchholz and colleagues at the Karolinska Institute are looking at victim's teeth to determine how old they are at the time of death. Using the Lawrence Livermore's Center for Accelerator Mass Spectrometry, Buchholz determined that the radioactive carbon-14 produced by above-ground nuclear testing in the 1950s and 1960s remains in the dental enamel, the hardest substance in the body. The radiocarbon analysis showed that dating the teeth with the carbon-14 method would estimate the birth date within one year. Age determination of unknown human bodies is important in the setting of a crime investigation or a mass disaster, because the age at death, birth date, and year of death, as well as gender, can guide investigators to the corr

  • A new study of the High Arctic climate roughly 50 million years ago led by the University of Colorado at Boulder helps to explain how ancient alligators and giant tortoises were able to thrive on Ellesmere Island well above the Arctic Circle, even as they endured six months of darkness each year.
  • The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering. In fiscal year (FY) 2010, its budget is about $6.9 billion. NSF funds reach all 50 states through grants to nearly 2,000 universities and institutions. Each year, NSF receives over 45,000 competitive requests for fu

    ScienceDaily (July 22, 2011) — Taking a trip down memory lane while you are driving could land you in a roadside ditch, new research indicates. Vanderbilt University psychologists have found that our visual perception can be contaminated by memories of what we have recently seen, impairing our ability to properly understand and act on what we are currently seeing.

    Software developed by an Israeli team is giving intriguing new hints about what researchers believe to be the multiple hands that wrote the Bible. The new software analyzes style and word choices to distinguish parts of a single text written by different authors, and when applied to the Bible its algorithm teased out distinct writerly voices in the holy book.
