NCI Releases Massive Data Set to Help Cancer Researchers
The National Cancer Institute (NCI) has released a massive data set of cancer-specific genetic variations to help the cancer research community gain a better understanding or both drug response and drug resistance to cancer treatments. The data set was published in Cancer Research, a journal of the American Association for Cancer Research. The database—the largest worldwide—includes 6 billion data points connecting “drugs with genomic variants for the whole human genome across cell lines from nine tissues of origin, including breast, ovary, prostate, colon, lung, kidney, brain, blood, and skin,” said Yves Pommier, MD, PhD, NCI’s chief of the Laboratory of Molecular Pharmacology. “Opening this extensive data set to researchers will expand our knowledge and understanding of tumorigenesis [the process by which normal cells are transformed into cancer], as more and more cancer-related gene aberrations are discovered,” he said. “This comes at a great time, because genomic medicine is becoming a reality, and I am very hopeful this valuable information will change the way we use drugs for precision medicine.” Read more on cancer.
FDA Approves Device that Uses the Brain’s Electrical Impulses to Diagnose ADHD
The U.S. Food and Drug Administration (FDA) has approved the marketing of the first medical device that will look at a brain’s electrical impulses to help determine whether children and adolescents have attention-deficit/hyperactivity disorder (ADHD). The 15-20 minute test for people ages 6 to 17, which utilizes electroencephalogram technology, can be used to confirm an ADHD diagnosis or help health professionals decide whether further testing should focus on ADHD. “Diagnosing ADHD is a multistep process based on a complete medical and psychiatric exam,” said Christy Foreman, director of the Office of Device Evaluation at the FDA’s Center for Devices and Radiological Health. “The NEBA System along with other clinical information may help health care providers more accurately determine if ADHD is the cause of a behavioral problem.” Read more on technology.
Study: Divorce When a Child is Young Negatively Impacts Later Parental Relationship Security
Young children whose parents divorce may have more difficult and less secure relationships with their parents later in life, according to a new study in the journal Personality and Social Psychology Bulletin. Researchers looked at date from 7,335 men and women with the average age of 24, finding those whose parents divorced when they were age 5 or younger had less secure parental relationships as adults. A secure relationship means that the child feels “they can trust them and depend on them and that the parent will be available psychologically,” according to HealthDay. The negative effect was especially true for relationships with the father. The study found that participants were more likely to have a “strained” relationship with the parent they did not live with after the divorce; about 74 percent of the participants lived with their mothers and only 11 percent lived with their fathers. Omri Gillath, an associate professor of social psychology at the University of Kansas, said the results demonstrate the need for divorcing parents to be as civilized as possible.
