Medscape (8/3, Lowry) reports, “A questionnaire for parents is a promising tool for identifying 12-month-old infants who are at risk for an eventual diagnosis of autism spectrum disorder (ASD),” according to a 699-patient study published online July 10 in Autism: The International Journal of Research & Practice. The “study showed that 31% of children identified by the inventory as being at risk for ASD at 12 months had a confirmed diagnosis by age three years.” What’s more, “85% of the children identified at 12 months had a developmental disability or concern by age three,” researchers reported.

MedPage Today (8/2, Smith) reports that “teens who expected to die young were more likely to indulge in risky behavior, including substance abuse and attempting suicide,” according to a study published online in the journal PLoS One. In addition, “the expectation of poor survival at the beginning of the study…was associated with an increase in the risk of dying in young adulthood, with those who had a low expectation of surviving to age 35 having death rates that were double those experienced by respondents saying they were ‘almost certain’ to reach that age,” researchers reported. The study’s “findings come from the National Longitudinal Study of Adolescent Health, a nationally representative survey that began with 20,745 adolescents in grades 7 through 12 during the 1994-1995 school year.”

Janice D’Arcy writes in a Washington Post (7/31) “On Parenting” blog, “A new study from the Substance Abuse and Mental Health Services Administration drew on a survey of about 250,000 children ages 12 to 17 and found they were far more likely to start using drugs and alcohol during the summer than during other parts of the year.” D’Arcy discussed the study with Mylene Krzanowski, executive director of the student assistance program at the Caron Treatment Centers, who said parents must “clearly state a no-use message and…provide their teen with the accurate information as to why they have this expectation.”

The New York Times (8/1, O’Connor) “Well” blog reports, “For those with heart failure, exercise may help ease depression,” according to astudy published in the Journal of the American Medical Association.

Reuters (8/1, Pittman) reports that researchers followed about 2,300 heart failure patients, about half of whom were randomly assigned to participate in an in-home exercise program, in addition to receiving standard heart failure treatment. The remaining patients were assigned to receive only standard treatment.

MedPage Today (8/1, Neale) reports that the researchers found that “at both three and 12 months, patients who were exercising in addition to receiving usual care had modestly but significantly reduced depressive symptom scores compared with those who were receiving usual care alone.”

WebMD (8/1, Goodman) reports that additionally, “the exercisers were about 15% less likely to die or be hospitalized for heart failure compared with the group getting usual care.”

HeartWire (8/1, Stiles) reports that study author Dr James A Blumenthal “said for heartwire, the magnitude of benefit was tied to how much the patient exercised. ‘It didn’t require marathon training. It looks like about 90 minutes a week, or three 30-minute sessions, was really sufficient to reduce depressive symptoms.'”

BBC News (8/1, Selvadurai) reports, “People with mild mental illnesses, such as anxiety or depression, are more likely to die early,” according to a study published online July 31 in the BMJ. For the study, researchers “looked at data over 10 years and matched it to information on death certificates.” They found that “low level distress raised the risk by 16%, once lifestyle factors such as drinking and smoking were taken into account,” and that “more serious problems increased it by 67%.”

The UK’s Telegraph (8/1, Adams) reports that people with subclinical anxiety or depression may also be “at a 29 per cent increased risk of dying from ‘external causes’ like road accidents and suicide, although these only accounted for a tiny proportion of deaths.” Previously, “it had been thought that depressed or anxious people were more likely to die early because they failed to take good care of themselves — perhaps smoking and drinking more, eating worse and doing less exercise.” However, according to the study’s lead author, stress may alter “the physiology of the body to make it intrinsically less healthy,” somehow making it more susceptible to stroke and heart attacks.

“Professor Glyn Lewis, of the University of Bristol, reviewed the findings for the journal and said they add to evidence suggesting a causal association between psychological distress and heart disease, although it is not clear how to intervene,” the UK’s Daily Mail (8/1, Watson) reports.

WebMD (8/1, Goodman) reports, “The study findings did not surprise Viola Vaccarino, MD, PhD, a cardiologist and professor of medicine at Emory University in Atlanta who studies the role of depression in heart disease.” Dr. Vaccarino, who was not involved in the study, stated, “Clearly there is evidence that depression is a risk factor for cardiovascular disease and total mortality as well.”

Reuters (7/31, Rosen) reports that, according to a study by the Alaska Department of Health and Social Services, Alaska Native men in their twenties may face a very high risk of suicide. Researchers found that individuals from this group commit suicide at a rate that is roughly 13 times higher than the US average.

MedWire (7/31, Cowen) reports, “Symptoms of elation and irritability are significantly associated with an increased likelihood for developing bipolar disorder (BD),” according to a study published online July 27 in the Journal of Affective Disorders. The study findings “come from a study of 40,512 individuals who participated in the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) who did not meet criteria for mania/hypomania at baseline in 2001-2002.”

The Augusta (GA) Chronicle (7/25, Martin) noted, “An online chat service of the Department of Veterans Affairs’ national crisis hot line has experienced a 62 percent increase over last year, according to information provided” by the department. The Chronicle added, “The data are further evidence that veterans are responding to…VA’s increasing use of technology, said Lisa Gerardot, the suicide prevention case manager at the uptown VA hospital in Augusta. It’s especially critical that resources are accessible from different points because with younger veterans, ‘it’s a reflex for them to reach for an electronic device,’ she said.”

MedPage Today (7/26, Kaiser) reports, “Stroke survivors are at an increased risk of post-traumatic stress disorder (PTSD), which in turn increases the likelihood of poor medication adherence,” according to a 535-patient study published in the August issue of the journal Stroke: Journal of the American Heart Association. “Two-thirds (67%) of those who were diagnosed with PTSD following stroke or transient ischemic attack (TIA) were not compliant with their medication,” the study found. “After adjusting for demographic and clinical predictors of non-adherence, PTSD was associated with a nearly threefold increase in the risk of medication noncompliance,” researchers reported.

The New York Times (7/25, Span) “New Old Age” blog reported that a study published June in the journal Psychiatric Clinics of North America “found that only 19 percent of elders with diagnosed depression who received ‘usual care’ in primary care practices showed substantial improvement.” This can possibly be explained by the fact that “a great majority of older people seek treatment through their primary care doctors, few of whom are able to offer much more than a prescription.” Another study, published last June in the Journal of the American Geriatrics Society, found that “as diagnosis rates climbed, more than two-thirds of older patients with depression received antidepressants, but the proportion receiving psychotherapy declined, to less than 15 percent.”
