According to the latest results of a large screening trial, annual screening for prostate cancer doesn’t cut men’s chances of dying from the disease.

Researchers found while comparing men who were screened each year with so-called PSA tests, for prostate specific antigen, or rectal exams to those who received their usual care that more men in the screening group had been diagnosed with prostate cancer after 13 years and there was no difference in how many had died from it.

“Men, if they’re considering screening, should be aware that there’s a possibility that there’s little or no benefit (and) that there certainly are harms to PSA screening,” said study co-author Philip Prorok, from the National Cancer Institute in Bethesda, Maryland.

According to an international study, children who get more exercise also tend to do better in school.

The findings come as schools in the United States, in general, cut physical activity time in favor of more academic test preparation.

Amika Singh, who worked on the study, said, “Maybe it’s an activity break, stand up every half an hour in class and do something,” said Singh, from VU University Medical Center in Amsterdam.

“It might mean going to school by bike … Any kind of physical activity you can think of. It doesn’t mean only the physical education standard class.”

The findings were published in the Archives of Pediatrics & Adolescent Medicine.

According to researchers from the United States, some adolescent girls who get the HPV vaccine for preventing cervical cancer wrongly think they no longer need to practice safe sex.

The study, which was published in the Archives of Pediatric & Adolescent Medicine, demonstrated the need for better education about the vaccines and their limitations.

Merck’s Gardasil and GlaxoSmithKline’s Cervarix vaccines protect against strains of the humanpapilloma virus or HPV but do not prevent other forms of sexually transmitted diseases such as syphilis, gonorrhea, or human immunodeficiency virus or HIV that causes AIDS.

“Clinicians discussing HPV vaccination with girls and their mothers may need to emphasize the limitations of the vaccine and to specifically address that the vaccine does not prevent other sexually transmitted infections,” the team wrote.
