According to the New York Times (12/31, Bakalar) “Well” blog, a review published online Dec. 22 in Clinical Gastroenterology and Hepatology suggests that psychotherapy may be “effective in easing the symptoms of irritable bowel syndrome…even after therapy has ended.” After examining “data from 41 clinical trials that included 1,183 people assigned to psychotherapy and 1,107 controls,” investigators found that one year “after the end of treatment, 75 percent of the treatment group had greater symptom relief than the average member of the control group, although the benefits were modest.”

Reuters (12/31, Rapaport) reports that a small magnetic resonance imaging study published online Dec. 8 in the Journal of Adolescent Health revealed that teenage participants who identified themselves as smokers had heightened responses in dopamine-rich brain regions after watching videos of actors smoking. According to the study authors, the maturing teenage dopamine system causes the brain as a whole to react more significantly to rewards and thrills, which may render adolescents more susceptible to addiction.

The Los Angeles Times (12/29, Kaplan) reports in “Science Now” that “even after overdosing on opioid medications, more than nine out of 10 patients continued to get prescriptions for the powerful” pain medicines, a study published online Dec. 29 in the Annals of Internal Medicine indicated. Consequently, some patients “went on to suffer another overdose,” the study of 2,848 opioid overdose patients found.

The CBS News (12/29, Marcus) website reports that “seventy percent received prescriptions from the same” healthcare professional “who prescribed opioids before their first overdose.” The study “only included patients on private insurance and did not take into account those on Medicare and Medicaid who might also be vulnerable to opioid overdoses, said” lead author Marc LaRochelle, MD. The research “was primarily of patients prescribed the powerful” medications “for musculoskeletal pain – such as lower back or knee pain, for example – not cancer patients.”

The New York Times (12/25, A20, Bidgood, Subscription Publication) reported on a study by Centers for Disease Control and Prevention on an outbreak of gun violence in Wilmington, DE. The Times said that shootings had gone up 45% between 2011 and 2013 and have remained stubbornly high.

The Times pointed out that researchers have called the study “a fairly rare look at gun violence by an agency that they say has been effectively limited for nearly two decades in pursuing that line of inquiry by its congressional appropriation.” The study concluded, “The majority of individuals involved in urban firearm violence are young men with substantial violence involvement preceding the more serious offense of a firearm crime.”
