- Bundling HIV Prevention with Prenatal Care Reduces Risky Sex Behaviors Among At-risk Mothers
- Science Update February 22, 2010
An HIV-prevention program targeted at women receiving prenatal care may effectively reduce risks for HIV, sexually transmitted infections (STIs), and unplanned future pregnancies, according to NIMH-funded researchers. Bundling such interventions into existing health care models, like prenatal care, also may be more accessible to those who may not have the time, interest, or resources to attend a stand-alone HIV prevention program. Changing the way prenatal care is provided also may create sustainable advantages in reproductive health for all at-risk women. The study was published in the November 2009 issue of the American Journal of Public Health.
- Teaching Teens About Abstinence May Delay Sexual Activity, Reduce Risk Behaviors
- Science Update February 02, 2010
Teens who received a behavioral intervention centered on abstinence were more likely to delay first sexual contact than teens who received a control intervention focusing on general health promotion, according to an NIMH-funded study. Though differing from federally funded abstinence-only programs, the researchers describe how an abstinence-based intervention may help delay sexual activity among adolescents in the February 2010 issue of the Archives of Pediatrics and Adolescent Medicine.
- Genes and Circuitry, Not Just Clinical Observation, to Guide Classification for Research
- Science Update January 28, 2010
NIMH is launching a long-term project aimed at ultimately improving treatment and prevention by studying classification of mental illness, based on genetics and neuroscience in addition to clinical observation. The Research Domain Criteria (RDoC) project is not intended to replace psychiatry’s existing diagnostic system for practitioners and will proceed in an independent direction, said Bruce Cuthbert, Ph.D., Director of the NIMH Division of Adult Translational Research, who is directing the effort. By taking a fresh look – without preconceived categories – the project aims to improve the validity of classification for researchers.
- Same Genes Suspected in Both Depression and Bipolar Illness
- Science Update January 28, 2010
Researchers, for the first time, have pinpointed a genetic hotspot that confers risk for both bipolar disorder and depression. People with either of these mood disorders were significantly more likely to have risk versions of genes at this site than healthy controls. One of the genes, which codes for part of a cell’s machinery that tells genes when to turn on and off, was also found to be over-expressed in the executive hub of bipolar patients’ brains, making it a prime suspect. The results add to mounting evidence that major mental disorders overlap at the molecular level.
- From Neurons to Thought: Coherent Electrical Patterns Observed Across the Brain
- Science Update January 25, 2010
Amidst the background hum of electrical signaling generated by neurons in the brain, scientists have found that local groups of neurons, firing in coordination, sometimes create a signal that is mirrored instantaneously and precisely by other groups of neurons across the brain. These transient episodes of coherence across different parts of the brain may be an electrical signature of thought and actions.
- New Grant Aims to Identify and Reduce Suicide Among Emergency Department Patients
- Science Update January 13, 2010
