Total Knee Replacement Appears Cost-Effective In Older Adults
Total knee replacement (arthroplasty) appears to be a cost-effective procedure for older adults with advanced osteoarthritis, according to a report in the June 22 issue of Archives of Internal Medicine, one of the JAMA/Archives journals. The procedure appears to be cost-effective across all patient risk groups, and appeared more costly and less effective in low-volume centers than in high-volume centers.

Medtronic Announces Two Worldwide Clinical Trials To Study Medical Device Interventions For Stroke
Each year, approximately 795,000 people experience a new or recurrent stroke1 in the United States, and approximately a half million people in Western Europe are similarly afflicted2. Today, Medtronic, Inc. (NYSE: MDT) announces two significant clinical trials related to medical device interventions for stroke. First enrollments in the global CRYSTAL AF (Study of Continuous Cardiac Monitoring to Assess Atrial Fibrillation After Cryptogenic Stroke) trial have taken place. The trial will use the Reveal® XT Insertable Cardiac Monitor (ICM) to assess the incidence of atrial fibrillation (AF) in patients with cryptogenic stroke (stroke of an undetermined cause) or transient ischemic attack (TIA) in order to aid physicians in determining the optimal course of treatment for these patients. It is widely recognized that patients with sustained AF are at increased risk of stroke3.

Two University of Denver Studies Look At Why Couples Live Together And The Results When They Do

University of Denver (DU) researchers find that couples who live together before they are engaged have a higher chance of getting divorced than those who wait until they are married to live together, or at least wait until they are engaged. In addition, couples who lived together before engagement and then married, reported a lower satisfaction in their marriages. The research, which appears in the Journal of Family Psychology, was conducted by Galena Rhoades, senior researcher, Scott Stanley, research professor, and Howard Markman, professor of psychology. "We think that some couples who move in together without a clear commitment to marriage may wind up sliding into marriage partly because they are already cohabiting," Rhoades says. "It seems wise to talk about commitment and what living together might mean for the future of the relationship before moving in together, especially because cohabiting likely makes it harder to break up compared to dating," Stanley says. The three researchers also studied the reasons why couples decide to live together. That study, which appeared in the Journal of Family Issues, shows that most couples chose to live together in order to spend more time together. The second most popular reason is convenience, followed by testing the relationship. This is different than previous research that found most people cohabit to test the relationship. "Cohabiting to test a relationship turns out to be associated with the most problems in relationships," Rhoades says. "Perhaps if a person is feeling a need to test the relationship, he or she already knows some important information about how a relationship may go over time." Kristal Griffith University of Denver
