CNN (9/15, Enayati,) reported that “several recent studies underscore how critically important it is for those fighting” cancer “to learn how to combat stress.” For instance, in a study recently published in PLoS ONE, “a team of researchers led by Lorenzo Cohen, professor of general oncology and director of the Integrative Medicine Program at The University of Texas MD Anderson Cancer Center, found that symptoms of depression among a group of patients with late-stage renal cell carcinoma were associated with an increased risk of death.” The primary “suspects in Cohen’s study: cortisol — also known as the ‘stress hormone’ — and inflammatory pathways.”

HealthDay (9/14, Dallas) reports that adolescents who are “new smokers suffer nearly all of the same negative psychological effects when they try to quit as people who’ve smoked for years,” according to an analysis published online Sept. 4 in the journal Nicotine and Tobacco Research. Scientists at Brown University Center for Alcohol and Addiction Studies divided the study population, which ranged in “age from 13 to 19,” into three groups: “22 nonsmokers, 27 smokers who did not change their habit, and 47 smokers who avoided cigarettes for almost a full day.” They noted that the “teen smokers had about nine cigarettes each day for about two years”; and after quitting the habit, the researchers found that the teens “experienced the same withdrawal symptoms, smoking urges, negative mood swings and intense cravings as those recorded in adults.”

Study Links Secondhand Smoke To Memory Problems. HealthDay (9/14, Dallas) reported that secondhand smoke “has a negative effect on brain function,” according to a study published online “recently” in the journal Addiction. Over four and a half years, researchers at Northumbria University in the UK “compared a group of smokers” with one group of nonsmokers “exposed to secondhand smoke either at home or in a ‘smoking area’ for an average of 25 hours a week” and one group of nonsmokers not exposed to secondhand smoke. An “event-based memory test, which focuses on memory for future intentions” showed that nonsmokers in the secondhand smoke group “forgot almost 20 percent more” than did the other nonsmoking group; and smokers forgot “30 percent more than those who were not exposed to secondhand smoke.”

HealthDay (9/14, Dotinga) reports, “New research suggests that Hispanic children with developmental delays often are undiagnosed, and both Hispanic and non-Hispanic kids who are diagnosed with developmental delays often actually have autism.” Investigators looked at data on more than 1,000 California children. The researchers found that, “of the Hispanic kids in the study, 6.3 percent had signs of developmental delay compared with 2.4 percent of non-Hispanics.” The investigators reported that, “of the children overall, about 19 percent who had been diagnosed with developmental delay actually appeared to have autism.” The findings are published in the journal Autism.

Medscape (9/14, Brauser) reports that “new research suggests that long-term psychotherapy can decrease defensiveness” in patients with psychiatric disorders. “The observational study, which included 21 adults with anxiety, depression, or personality disorders, showed significant changes in the participants’ defensiveness after roughly 2.5 years of dynamic psychotherapy.” The researchers reported that “these changes were then significantly associated with improvements in both symptoms and overall functioning 2.5 years later.”

The New York Times (9/12, Reynolds) “Well” blog reports that “a growing and very appealing body of science has established that exercise spurs the creation of new brain cells, a process known as neurogenesis.” According to a study published last month in Proceedings of the National Academy of Sciences, “male sex hormones surge in the brain after exercise and could be helping to remodel the mind. The research was conducted on young, healthy and exclusively male rats – but scientists believe it applies to female rats, too, as well as other mammals, including humans.”
