Spending on mental and substance use disorders concentrated in the public sector
The percentage of mental health and substance abuse services paid for by public sources is increasing, with a smaller percentage provided by private sources, including private health insurance. Public sources paid for 63 percent of mental health spending in 2001, up from 57 percent in 1991.  more

Over a third of youth 12-17 used alcohol in the past year; 9 million engaged in delinquent behavior
Almost 8.6 million youths ages 12 to 17, over one third of this age group, used alcohol in the past year, data from the Substance Abuse and Mental Health Administration (SAMHSA) show.  The data, released today as part of Alcohol Awareness Month, show more than 650,000 youth (2.6 percent) reported heavy alcohol use, and nine million engaged in at least one delinquent behavior in the past year.  more

National expenditures for mental health services and substance abuse treatment 1991-2001
The report addresses the following key questions: How much was spent in the United States in 2001 to provide mental health services and substance abuse treatment (MHSA) and its component parts—mental health (MH) and substance abuse (SA)? How are the expenditures for each component distributed by payer and provider type? How has spending changed from 1991 to 2001? How do MHSA expenditures compare with those for all U.S. health care?  more


Long-term data show uterine fibroid embolization is effective treatment for uterine fibroids
Data presented at the 30th Annual Scientific Meeting of the Society of Interventional Radiology found that the nonsurgical embolization treatment for uterine fibroids had a 73 percent success rate at five years. Uterine fibroid embolization (UFE) is a minimally invasive interventional radiology treatment that blocks the blood supply to the fibroid tumors, causing them to shrink and die, alleviating symptoms.  more

New study shows subintimal angioplasty and selective stenting restores blood flow and prevents amputation in severe peripheral arterial disease
This study, presented at the 30th Annual Scientific Meeting of the Society of Interventional Radiology, shows that treating long segments of the blocked artery with subintimal angioplasty, followed by stenting as needed, is highly successful in restoring blood flow nonsurgically and preventing amputation. Subintimal angioplasty differs from the usual intraluminal angioplasty because subintimal angioplasty is performed in the wall of the artery to create a new nondiseased channel underneath the diseased lumen area, whereas traditional angioplasty opens the narrowed lumen. The study examines treating long segments of small vessels in the legs and feet (the superficial femoral arteries and tibial arteries) in patients with chronic critical limb ischemia.  more

Prospective, multicenter lung cancer trial shows heat directly kills tumors in 93 percent of cases
After receiving treatment of radiofrequency heat to "cook" and kill their lung tumors, patients had a 91 percent cancer-specific survival rate at one and two years, according to results of a prospective, multicenter trial that was presented at the Society of Interventional Radiology's 30th Annual Scientific Meeting. The research also showed the radiofrequency ablation (RFA) technique successfully killed the tumor inside the body without surgery in 93 percent of the cases. During radiofrequency ablation, an interventional radiologist inserts a small, energy-delivering probe through the skin, directly into the tumor using imaging for guidance. Heat is delivered through the probe to destroy the tumor cells without significant side effects or damage to nearby normal tissue. more

'Mandela's Paradox' may show that osteoporosis propensity starts in pre-teen years
After Nelson Mandela was released from prison February 11, 1990, all children born in the greater Johannesburg area were enrolled in a 20-year longitudinal study. Officially known as "Birth to Twenty," the study and its 3,273 youth, are colloquially referred to as "Mandela's Children." It's the largest and longest running study of child and adolescent health and development in Africa, and one of the few large-scale longitudinal studies in the world. One of the main aims of the study is to follow bone health in growing children, specifically the differences in bone mass acquisition between black and white children and the factors that influence this.  more
