Researchers at UC San Diego School of Medicine have identified a clear group of characteristics that predict heightened risk for experiencing increased anxiety or worsening of mood that interferes with daily activities when using a smoking cessation drug. Results are published in the Feb. 27 online edition of the Journal of General Internal Medicine.
The higher the cotinine levels were in the mother's blood during pregnancy, the greater was the child's risk of developing attention deficit hyperactivity disorder (ADHD) later in life, showed an epidemiological study conducted by the Research Centre for Child Psychiatry at the University of Turku, Finland. Globally, it is the first study in which the connection between fetal nicotine exposure and diagnosis of ADHD was shown by measuring cotinine levels from pregnant maternal serum specimens.
Researchers at the University of New Mexico recently solved a major gap in scientific literature by using mobile software technology to measure the real-time effects of actual cannabis-based products used by millions of people every day.
The damage done to America's health by the opioid epidemic is well-recognized and enormous, with drug overdose death rates helping to drive down US life expectancy in recent years. Yet as the problem has worsened, American hospitals collectively have seen a loss of programs dealing with substance abuse.
Some variations in the gene LPHN3-associated with the attention deficit / hyperactivity disorder (ADHD) in kids and adults -- could favor likelihood to smoke, consume alcohol, cannabis and other addictive substances, according to an article published in the journal Translational Psychiatry, from the Nature Publishing Group.
A powerful neuroscience tool is available to investigate brain development, mechanisms of memory and learning, and brain dysregulation in neuropsychiatric diseases like addiction, depression, schizophrenia and Alzheimer's disease. This molecular biology tool can selectively and robustly turn on genes in vitro and in brain neurons of living adult rats. It can turn on a single gene or multiple genes at the same time, and it can control the amount of increased gene expression.
Researchers at the University of Texas at San Antonio have studied the opioid epidemic in a representative sample from the United States and found that the majority of people misusing prescription opioids are also using other licit and illicit substances.
A survey of marijuana and tobacco co-users by Medical University of South Carolina investigators found that co-users with high degree of interrelatedness between their use of the two substances had greater tobacco dependence and smoked more cigarettes per day. However, the finding of a strong link between the two substances was not universal. These findings, reported in Addictive Behaviors, suggest that highly personalized treatments are needed for co-users who want to quit smoking.
Opioid-related deaths nationwide jumped fourfold in the last two decades, and the epidemic has made major inroads in the Eastern states, according to a new study by researchers at the Stanford University School of Medicine, Harvard University and the University of Toronto.
A USC study found that the United States has the highest drug overdose death rates among a set of high-income countries. The study found that drug overdose death rates in the United States are 3.5 times higher on average when compared to 17 other high-income counties. The study is the first to demonstrate that the drug overdose epidemic is contributing to the widening gap in life expectancy between the United States and other high-income countries.
