The link between childhood trauma, a faulty stress response and suicide risk in later life

When people experience stress, the adrenal glands that sit on top of the kidneys release a steroid hormone called cortisol. However, our latest study shows that people who have experienced high levels of trauma in childhood, and who have attempted suicide, tend to release less cortisol when put under stress. These findings build on our earlier work that showed that the stress response system may be "faulty" or "damaged" in people who have recently tried to take their own life.

Reforms to improve access to affordable, high quality child care

For families in the U.S., the costs of high-quality child care are exorbitant, especially for those with children under age five. A new policy proposal, "Public Investments in Child Care," by Dartmouth Associate Professor of Economics Elizabeth Cascio, finds that current federal child care tax policies are not benefiting the families most burdened by childcare costs. Therefore, Cascio outlines a new policy that could replace the current federal child care tax policies. The research examines child care for children ages 0-12 years, with a focus on 0-4 years.

Predictors of Life Expectancy Inequality

According to new study findings published in the JAMA Intern Medicine, multivariable analyses that include the risk factors suggest that the variations in life expectancy are largely explained by behavioural and metabolic risk factors, with socioeconomic and race/ethnicity factors no longer being statistically significant.

Quest MRI to Identify Earliest Signs of Alzheimer's Disease in Mice

Alzheimer's disease begins before the signs of memory loss, so some recent scientific efforts have focused on recognizing the earliest signs that portend disease onset. Those telltale signs, called biomarkers , would enable patients to receive treatment for Alzheimer's sooner. So, the National Institutes of Health called for research proposals to find new ways to diagnose Alzheimer's disease and predict its progression.

Socioeconomic causes in low-income areas could predict heart failure risk

According to new research in Circulation: Cardiovascular Quality and Outcomes, an American Heart Association journal. Neighborhood-level socioeconomic factors in low-income areas may significantly predict heart failure risk beyond individual health factors and socioeconomic status. Researchers grouped the participants in three groups ranging from the least-deprived to the most-deprived neighborhoods. During an average follow-up of more than five years, 4,300 participants were diagnosed with heart failure.
