Mothers' stress may increase children's asthma

Children whose mothers experience chronic stress during early years have a higher asthma rate than peers. Long-term maternal stress was associated with an increase in nearly a third of childhood asthma prevalence. Maternal distress also intensified risk under specific home environments, such as high-income households or sibling presence.

HIV shifting from most to least educated in sub-Saharan Africa

A study finds that HIV prevalence falls more consistently among highly educated groups than less educated ones in sub-Saharan Africa. The research suggests that while HIV education campaigns led to a decline in infections among the well-educated, they had little impact on the least educated populations.

Cancer study finds adolescents don't get same access to latest treatments as younger patients

A recent study by Children's Hospital of Pittsburgh found that adolescents and young adults with cancer are less likely to be enrolled in clinical trials for cutting-edge treatments. This can lead to lower survival rates compared to younger children, who have seen significant improvements in cure rates over the past 30 years.
