The Washington Post (4/1, A4, Brown) reported, “Numerous studies have shown that repeated deployment is a ‘risk factor’ for” post-traumatic stress disorder (PTSD). For example, a study published in the March issue of the American Journal of Public Health “examined the experience of 66,000 Marines who served in Iraq. Those with two deployments had almost twice the rate of PTSD as those deployed once.”

PTSD Susceptibility May Be Partially Determined By Gene Variants. BBC News (4/2) reports, “Susceptibility to post-traumatic stress disorder (PTSD) could be partially determined by gene variants,” according to a study published in the Journal of Affective Disorders. After examining “DNA from 200 members of 12 families who survived the 1988 Armenian earthquake,” researchers found that “those who carried two gene variants which affect the production of serotonin — which affects mood and behaviour — were more likely to display symptoms of PTSD.”

MedPage Today (4/1, Smith) reported, “People said they would pay more to avoid some serious medical conditions than they would to avoid severe mental illnesses, such as schizophrenia and depression,” according to survey results published in the April issue of the journal Psychiatric Services. In the survey involving some 1,000 randomly chosen US adults, “respondents recognized that the two mental conditions had a health burden comparable to or higher than diabetes, below-the-knee amputation or partial blindness, according to Dylan Smith, PhD, of Stony Brook University in Stony Brook, NY, and colleagues.” Notably, “for a comparable benefit in terms of quality of life, participants in the study were willing to pay about 40% less to avoid the psychiatric illnesses,” the study authors reported.

The Huffington Post (3/30, Chan) reports, “Soldiers, police, firemen and people who’ve suffered abuse aren’t the only ones with a high risk for post-traumatic stress disorder (PTSD) — a new study” published online March 29 in the Journal of Traumatic Stress “shows that 911 dispatchers may be at risk, too.” Investigators “from Northern Illinois University found that the 911 dispatchers still experienced the emotional distress associated with PTSD, even though they were not directly in the traumatic event.”

The Time (3/30, Sifferlin) “Healthland” blog reports that for the study, “researchers questioned 171 emergency dispatchers currently working in 24 US states. The dispatchers — predominately white women around age 38 with more than 11 years of dispatching experience — were asked about the types of calls they answer and their corresponding emotional distress.” Next, “participants…rated the types of calls that caused great distress and were asked to recall the worst call they ever received.”

“The unexpected injury or death of a child accounted for 16 percent of the calls dispatchers identified as their worst trauma,” HealthDay (3/30, Dallas). “The study authors noted that the dispatchers experienced a high level of distress following an average of 32 percent of potentially traumatic calls. In addition, 3.5 percent of the dispatchers reported symptoms severe enough to be classified as PTSD.”

A new report on autism rates in the US received heavy coverage in print and online, and was discussed for nearly ten minutes on last night’s national news broadcasts. ABC World News (3/29, story 2, 2:45, Sawyer) reported, “A new report from the Centers of Disease Control shows a big increase in the number of American children diagnosed with autism.”

The CBS Evening News (3/29, story 2, 3:00, Pelley) reports that Dr. Colleen Boyle of the CDC, who “oversaw the study,” said, “No matter what the number is, there’s one thing for certain, and that is that more children are being identified with autism.”

On NBC Nightly News (3/29, lead story, 2:45, Holt), Dr. Boyle, said, “Since 2002, the problems have increased 78%.”
In a second segment on NBC Nightly News (3/29, story 2, 1:10, Holt), Dr. Alanna Levine, of the American Academy of Pediatrics, said, “We need to allocate” research funds “towards finding out what is causing the autism spectrum disorders, and how we can help these children and it can also help communities allocate resources to make sure there are services available for children who need them.”

The AP (3/30, Stobbe) reports, “The CDC study is considered the most comprehensive US investigation of autism prevalence to date. Researchers gathered data from areas in 14 states — Alabama, Arizona, Arkansas, Colorado, Florida, Georgia, Maryland, Missouri, New Jersey, North Carolina, Pennsylvania, South Carolina, Utah and Wisconsin.” The report indicates that “one child out of 88 in the US” has “autism or a related disorder.”

USA Today (3/30, Weintraub) reports that the “figures…show a 23% increase in autism spectrum cases from 2006 to 2008, and 78% increase since 2002.” CDC Director Thomas Frieden, MD, said, “What we do know for certain is autism is common and needs to be effectively served.”

According to the Washington Post (3/30, Brown), the report found that “autism is five times as common in boys as girls (a lopsided ratio found in many other studies).” Researchers also found that “the fraction of autistic children with average or above-average intelligence has risen more than the fraction with ‘intellectual disability.'” Meanwhile, “autism prevalence in Hispanic children is two-thirds that of white children, but it is rising faster in them and in black children than in white ones.”

MedPage Today (3/29, Gever) reports that the Food and Drug Administration (FDA) “has reworded warnings about potentially fatal arrhythmias associated with the antidepressant…citalopram (Celexa), acknowledging that some patients may need the drug despite the risks.” Last year, “the agency ordered numerous changes to the drug’s label, including one stating that citalopram is contraindicated in patients with congenital long QT syndrome.” However, yesterday the FDA “announced that the label should say merely that the drug is ‘not recommended’ in these patients because, as the agency explained, ‘it is recognized that there may be some patients with this condition who could benefit from a low dose of citalopram and who lack viable alternatives.'”

“Patients at high risk include those with preexisting heart conditions (including congestive heart failure) and those prone to low levels of potassium and magnesium in the blood, the FDA said,” HealthDay (3/29, Preidt) reports. “At the time, the drug label was revised to include the new dosage limit as well as information about the potential for abnormal heart electrical activity and rhythms.” The current “recommendations note that Celexa in any dose should not be given to patients with certain conditions due to the risk of suffering these heart problems,” but “it may be important for some patients to take Celexa, so the label has been changed.”
