Merck's Gardasil Effective At Preventing HPV, Cervical Disease In Older Women, Study Finds
Merck"s human papillomavirus vaccine, Gardasil, was 90% effective in preventing infection with the virus and cervical disease in women ages 24 to 45, according to a study published Monday in the medical journal Lancet, Reuters reports (Fox, Reuters, 6/1). In the U.S., the vaccine currently is FDA-approved for girls and women ages nine to 26. Centers for Disease Control and Prevention guidelines recommend routine three-dose vaccination of girls ages 11 and 12 and for girls and women ages 13 to 26 who have not yet been vaccinated (CDC fact sheet, June 2008). It is designed to protect against HPV types 16 and 18, which cause about 70% of all cervical cancer cases, and HPV types 6 and 11, which cause genital warts.The new study, led by Nubia Munoz of the National Institute of Cancer in Bogota, Colombia, and funded by Merck, involved women ages 24 to 45 with no history of cervical disease or genital warts who either received the vaccine or a placebo injection. The study found that women who received the vaccine were significantly less likely to be infected with certain strains of HPV than those who received placebo shots. According to the researchers, four women out of 1,900 who received the vaccine developed HPV or cervical disease after two years, compared with 41 women out of 1,900 in the placebo group.Reuters reports that the results of the study could help Merck as it seeks approval for marketing Gardasil for use in older women. The researchers said in the study that older women might be at risk for HPV infection as "[c]hanges in sexual behavior during the past 30 years ... have led to more widespread premarital sexual intercourse and acquisition of new sexual partners around middle age." They added, "As the potential for HPV infection and disease exists in women in their third, fourth and fifth decades of life, these women could benefit from prophylactic HPV vaccination." According to Reuters, a mathematical model published in October 2005 showed that vaccinating older women could cut rates of cervical cancer in women through age 45 by half. Merck also has released data showing the effectiveness of the vaccine in preventing genital lesions in men.According to the Centers for Disease Control and Prevention, HPV is the most common sexually transmitted infection worldwide, and about 20 million U.S. residents are infected with it. The virus is the leading cause of cervical cancer, which causes about 3,870 deaths in the U.S. and 300,000 deaths globally every year, and it also can cause anal, penile, mouth and neck cancer (Reuters, 6/1).

When Adult Patients Have Anxiety Disorder, Their Children Need Help Too
In what is believed to be the first U.S. study designed to prevent anxiety disorders in the children of anxious parents, researchers at the Johns Hopkins Children"s Center have found that a family-based program reduced symptoms and the risk of developing an anxiety disorder among these children.

Chinese Government Reports Abortion Statistics
Chinese state media on Thursday reported that women in the country have about 13 million abortions annually, the AP/Houston Chronicle reports. According to the China Daily newspaper, the actual number likely is much higher because the 13 million includes abortions performed in hospitals but not unreported procedures performed in rural clinics. Most of the abortions were among single young women who experts say know little about contraception. The paper also said that about 10 million pills for medical abortion are sold annually in the country. China imposed strict population controls in the 1970s that prohibit most couples from having more than one child. For married women, sterilization and the use of intrauterine devices are widely promoted and subsidized. However, Chinese policies typically do not address the needs of unmarried women, even as national attitudes have become more accepting of sex outside of marriage, the AP/Chronicle reports. According to the newspaper, about 62% of the abortions were among unmarried women ages 20 to 29. The Chinese report called the number of abortions "an unfortunate situation" but did not indicate whether the procedures are increasing or decreasing from year to year. National Population and Family Planning Commission official Wu Shangchun is quoted in the report as saying that almost half of the women seeking abortion had used no form of contraception. Wu also said that reducing abortions is a national challenge that requires significant effort. Peking University professor Li Ying said that sex education in China must be improved at the university level and that Chinese parents must do more to teach children about sex (AP/Houston Chronicle, 7/30).

"Jumping Gene" Diminishes The Effect Of A New Type 2 Diabetes Risk Gene

Research led by the German Institute of Human Nutrition (DIfE) has identified a new gene associated with diabetes, together with a mechanism that makes obese mice less susceptible to diabetes. A genomic fragment that occurs naturally in some mouse strains diminishes the activity of the risk gene Zfp69. The researchers also found that the corresponding human gene (ZNF642) is especially active in overweight individuals with diabetes. The results of the study, which also involved scientists from the University of Leipzig and the German Cancer Research Center in Heidelberg, are published July 3 in the open-access journal PLoS Genetics. According to the World Health Organization (WHO), around 1.6 billion people are overweight worldwide. The number of people with type 2 diabetes has increased accordingly to 230 million. The risk of developing type 2 diabetes is approximately 50% hereditary, but is also dependent on nutrition and lifestyle factors. In the present study, the researchers compared the genomes of different mouse strains. Some mouse strains were obese but had no strikingly elevated blood glucose levels and were less susceptible to diabetes. Other strains developed a severe malfunction of fat and glucose metabolism as they continued to gain weight, causing these mice to rapidly develop type 2 diabetes. According to the study, this difference is due to a small fragment of genetic information: a so-called "jumping gene" or "transposon" of viral origin, localized in a non-coding segment of the gene Zfp69, whose effect it diminishes. Without this genetic fragment, the risk gene is fully active and, in combination with obesity, leads to high blood sugar levels and malfunction of fat metabolism. The gene is also active in the fat tissues of overweight people suffering from diabetes more so than in healthy individuals. "Our data suggest that the protein product of the risk gene in obese individuals enhances the storage of fat in fat cells. As a result, excessive fat accumulates in the liver and this in turn contributes to the development of diabetes," explains Stephan Scherneck, first author of the study. "We have therefore discovered a new diabetes gene of similar importance in mice and humans," says Hans-Georg Joost, head of the study and scientific director of DIfE, "as well as a mechanism that has not been described before in connection with the heredity of diabetes and obesity." These data show the importance of studying in detail not only genes themselves but also transposons in their vicinity. Joost continued, "This transposon is quite active and almost completely "turns off" the Zfp69 gene. We have found indications that it is also active in other mouse genes. Since the human genome is full of such fragments, it is quite possible that they play a greater role than previously assumed." German Institute of Human Nutrition Potsdam-Rehbruecke
