Manifested in Adulthood

1 Fetal X-Ray Exposure May Impair Adult Memory

Researchers at Yale examined the impact of early life disturbances on brain development using fetal monkeys exposed to high levels of radiation. When their development was examined five years later, researchers found they had severe disabilities in working memory compared to monkeys with no radiation exposure. The monkeys showed no such impairment at an earlier age leading scientists to conclude that disturbances to the brain during fetal development produce cognitive dysfunction that becomes apparent at maturity. The monkeys received much higher doses of radiation than are received from a typical x-ray so, while researchers don’t suggest that fetal x-ray exposure causes memory problems in adults, they do emphasize the importance of this time during brain development.

Alcohol Included

2 Drugs Negatively Affect Sexual Performance

Researchers at Concordia U evaluated the effect of a wide range of drugs, including alcohol, on sexual performance and found that, while you may think a glass of wine is the perfect intro to a romantic evening, you’re better off with iced tea. "In this broad-based and wide-reaching study, it appears that drugs and sex don't mix well," says researcher, Dr. James Pfaus. Using animal studies to conduct their research because “only animal model studies can provide direct cause and effect data and physiological information,” scientists found that most of the drugs, including alcohol, decreased sexual performance although “low levels of alcohol removed inhibitory tendencies” and “acute caffeine consumption facilitated sexual behavior in both male and female rats.” Coffee, anyone?

Nine Hours Peaks Performance

3 Teens Perform Better When School Starts Later

For years, health experts have pushed for a delayed school start for teens who they say benefit from nine or more hours of sleep. Now, a pilot study in a small Rhode Island high school confirms this theory. They delayed classes from 8 am to 8:30 am and saw a significant improvement in adolescent alertness, reports sleep expert Judy Owens, MD. She says that its the biology of teens that creates not only the need for more sleep but a later sleep onset as well. "On a practical level, this means that the average adolescent has difficulty falling asleep before 11 p.m., so the ideal wake time is around 8 a.m." The delayed school start resulted in a 36 percent reduction in tardiness and absences and an 80 percent reduction in the percentage of students who were sleep deprived.

Getting Along Is Safer

4 Rudeness May Impact Work Performance

Rudeness in a work environment may affect performance, and that could be especially important for those working in the health care field. Rhona Flin, Professor of Applied Psychology at the University of Aberdeen, believes that experiencing or witnessing rudeness at work makes you more likely to make mistakes. Flin shared her opinion in a recent editorial published in BMJ (British Medical Journal). She believes that rudeness in health care settings may present a danger to patient safety and care. Flin writes that, "People concerned with patient safety should note that civility between workers may have more benefits than just a harmonious atmosphere."

Twin Sister and Husband Hung Out

5 Elderly Woman Kept Corpses on Couches

Despite violations of health codes and the creepy factor, Jean Stevens, an elderly woman living in the Pennsylvania town of Wyalusing, kept the corpses of her twin sister and husband on couches at her residence. According to Yahoo News, Stevens, who is 91 years old, had the embalmed bodies dug up because she wanted to be able to see them and talk with them. She's also claustrophobic and couldn't stand the thought of the bodies inside caskets in the ground. The husband's body was found on a couch in a detached garage, while the twin sister's body was discovered on a couch in a spare bedroom. A prosecutor has said that Stevens will be allowed to keep the bodies if she installs a mausoleum or crypt. Police haven't revealed who dug up the bodies that were adorning Stevens' couches.

Avoid Fatty Foods When Pregnant

6 Mother's High Fat Diet Increases Birth Defect Risk

Poor diet is known to affect fetal development, and British researchers from Oxford University studying mice have found that a high fat diet during pregnancy may influence the type or severity of certain birth defects such as congenital heart disease and cleft palate. Genetically altered mice fed a high fat diet before and during pregnancy had certain changes occur in the environment of the womb that increased the risk of cleft palate more than seven-fold. The risk of atrial isomerism, a defect where both atria of the heart are similar, increased by two times. The changes did not happen in the genetically normal offspring of mothers who had a high fat diet, suggesting that it is the combination of high fat diet and the genetic defect that is responsible, the researchers said.

No Help for Hips or Knees Either

7 Glucosamine Ineffective for Low Back Pain

A Norwegian trial has found that the popular dietary supplement glucosamine offers little or no relief for sufferers of chronic lower back pain caused by osteoarthritis. Lead researcher Philip Wilkens from the University of Oslo randomly assigned 250 patients with chronic back pain and degenerative lumbar osteoarthritis to 1,500 milligrams of glucosamine daily or an inactive placebo. Pain was measured using the Roland Morris Disability Questionnaire. While the pain was slightly lower at six months and one year after the study initiation, the findings were not statistically significant. On a good note, the supplement appeared to be safe without harmful side effects. Results are published in the July 7 issue of JAMA. Osteoarthritis affects more than 20 million Americans.

Lipitor for Kids

8 European Union Approves Lipitor for Children

The world's top-selling drug developed by Pfizer can now be given to children 10 and up in the European Union. Chewable Lipitor has been approved for children who have familial hypercholesterolemia, an inherited disease in which they develop extremely high levels of cholesterol in the blood. In 2002, Pfizer got the same approval for children in the United States. As obese patients get younger and are at increased for diabetes and heart disease, the use of cholesterol-lowering drugs is expanding. Lipitor is approved to decrease the risks of heart attack and stroke. The U.S. patent for Lipitor was due to expire at the end of November 2011, but a six month extension was approved and the same will be done in Europe to prevent hundreds of millions of dollars being lost to generic competitors.
