This study provides benchmark data on the use of imaging for back pain in an Australian ED, an area which has been largely unexplored. The rate of imaging in the ED was higher than previously reported in a General Practice setting. Consistent with guidelines, patients older than 70 were more than twice as likely to receive imaging compared to younger patients. It was beyond the scope of the current study to determine whether these images were clinically indicated and further research is required to determine if initiatives to reduce imaging in this population are warranted.
Paroxetine has antihypertensive properties during periods of psychological stress in psychiatrically healthy subjects with a history of CAD, and so should be evaluated for potential cardio-protective qualities.
Smoking-related disease is the single biggest preventable cause of morbidity and mortality in the United States, yet approximately 25% of Americans continue to smoke. Various dosage forms of nicotine replacement therapy increase smoking quit rates relative to placebo, but they generally do not result in 1-year quit rates of over 20%. To increase these rates, a number of nonnicotine agents have been investigated. Drugs that modulate noradrenergic neurotransmission (bupropion, nortriptyline, moclobemide) are more effective than those affecting serotonin (selective serotonin reuptake inhibitors, buspirone, ondansetron) or other neurotransmitters.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
