Patients who recover from hepatitis C have lower risk of reinfection

A new study found that individuals who had tested positive for hepatitis C but later tested negative were significantly less likely to become infected again compared to those who had never been infected. This suggests that previous exposure to HCV may be protective against reinfection, possibly on an immunologic basis.

Early childhood behavior predicts adolescent alcohol and drug use

A study published in Child Development found that children's behavior from age 3 can predict their likelihood of using alcohol and illicit drugs in adolescence. Lower levels of behavioral control and slower increases in resiliency are associated with early drinking and drug use, while higher resiliency is linked to reduced risk.

Most sexual assaults drug facilitated, UIC study claims

A recent study by University of Illinois Chicago researchers suggests that approximately 61.8% of sexual assault subjects have drugs in their system, with 4.2% reporting being drugged without knowledge.
