Teens’ Brains May Make Them More Susceptible To Addiction, Small Study Indicates

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.

Many Patients Who Overdose On Opioids Continue To Get The Medications, Study Finds

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.”

CDC Studies Outbreak Of Gun Violence In Wilmington, Delaware

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.”

CDC Data Reveal Where Americans Kill Each Other Most Often

The Washington Post (12/24, Ingraham) “Wonkblog” reported that according to data from the Centers for Disease Control and Prevention, “the risk of being killed by another person is lowest in New England and the upper Midwest, and highest in the deep South, particularly Mississippi and Louisiana.” The Post pointed out that Louisiana’s age-adjusted homicide rate of 11.67 per 100,000 people and Mississippi is a close second, at 11.41.

The Post also explained that the District of Columbia’s homicide rate is 13.67 deaths per 100,000 but that “comparing it to the more geographically diverse states isn’t very meaningful.” The Post wrote that “the homicide rate in Louisiana is a whopping nine times higher than the rate in New Hampshire, the state with the lowest homicide rate.”

Kids in Single Parent And In Step Families 3x Prone to Mental Health Problems

The Telegraph (UK) (12/27, Donnelly) reported that “a major study” conducted by University College London researchers suggests that youngsters “brought up by single parents and in step families are three times as likely to suffer from mental health problems.” The study, which included some “10,000 children, found that those brought up by both natural parents are far less likely to suffer severe emotional and behavioural problems.”

NFL Under Fire For Reportedly Withholding Funding For NIH Concussion Study

ABC World News (12/22, story 13, 0:25, Muir) reported that the NFL is “under fire” for “withholding $16 million from researchers investigating football-related head trauma.” The NFL was funding the study, which is being conducted by the National Institutes of Health, but the league was “reportedly critical of the doctor leading the project.” NFL officials are “disputing the report.”

The Washington Post (12/23, Larimer) reports on the ESPN “Outside the Lines” story, which claimed that the NFL “‘backed out’ of the planned seven-year, $16 million research project to attempt to diagnose chronic traumatic encephalopathy (CTE) in living patients.” The study was originally “to have been paid for by a $30 million grant from the NFL made to the National Institutes of Health in 2012.” However, “the NIH will fund the study itself, according to a Tuesday morning news release.”

The New York Times (12/23, B9, Belson, Subscription Publication) reports that the National Institutes of Health and the National Institute of Neurological Disorders and Stroke awarded the grant “as part of a long-term study of brain disease in former NFL and college football players, many of whom sustained multiple concussions on the field,” but the NFL “did not help pay for the grant.”

NIDA Researcher: Synthetic Marijuana “The Emerging Face Of Drug Abuse”

PBS NewsHour (12/23) correspondent William Brangham sat down with National Institute on Drug Abuse toxicologist Dr. Marilyn Huestis, among others, to discuss the “rise of the drug synthetic marijuana, commonly known as Spice or K2.” In the interview, Dr. Huestis predicted that synthetic marijuana will be “the emerging face of drug abuse for the future,” adding that some of the new drugs that come out are “very potent, up to 100 times as potent as cannabis.” She is studying the chemical composition of synthetic drugs in her lab and notes the challenges of identifying the “ever-changing cocktail of chemicals.”

US Alcohol Deaths Have Reached A 35-Year High, CDC Finds

The Washington Post (12/23, Ingraham) “Wonkblog” reports that US alcohol deaths have reached a “35-year high.” In 2014, some “30,700 Americans died from alcohol-induced causes, including alcohol poisoning and cirrhosis.” Excluded from this figure are “deaths from drunk driving, other accidents, and homicides committed under the influence of alcohol.” Were those deaths to be “included, the annual toll of deaths directly or indirectly caused by alcohol would be closer to 90,000, according to” a CDC report published Dec. 18 in the Morbidity and Mortality Weekly Report.

TIME (12/23, Chan) points out, “Excessive alcohol use is a leading cause of preventable death, according to the” CDC, accounting “for about 88,000 deaths each from 2006 to 2010, health officials said.”
