Background. With an increasing proportion of Americans using complementary or alternative medicine (GAM), physicians need to know which patients are using GAM to effectively manage care. Methods. In this cross-sectional study, telephone interviews were conducted with 1,584 South Garolina adults (ages 18 and older); 66% responded to the survey of demographics, general health, frequency of GAM use, perceived GAM effectiveness, and physician knowledge of GAM use. Results. A total of 44% had used a GAM during the past year. Increasing age and higher education were significantly associated with GAM use. More than 60% perceived GAM therapy as very effective, and 89% said they would recommend GAM to others. Physicians were unaware of GAM use in 57% of their patients using GAM. Conclusion. Gomplementary or alternative medicine use in this rural Southern state is similar to national usage. Users view GAM as effective. Physicians are frequently unaware of patients' GAM use. More research is needed to establish GAM effectiveness and how GAM affects medical care, training, and public health. MORE THAN 40% of Americans are using complementary or alternative medicine (CAM) to treat a range of health conditions or to stay healthy,'"^ and this usage increased during the 1990s.' Eisenberg et al' reported that 42.
When CH2FBr diluted in argon is codeposited with a beam of atomic lithium at 15°K , the free radicals CH2F and CH2Br are stabilized in sufficient concentration for observation of several infrared absorptions. Studies utilizing CD2FBr and CH2FC1 help confirm the spectral identity of the monofluoromethyl free radical. The new absorptions are assigned to the symmetric C-F stretching vibration of the CH2F and CD2F radicals, and the DCD bending mode of CD2F. The vibrational potential function giving the best fit of symmetric vibrational frequencies is determined and bonding in CH2F is discussed.
Simultaneous deposition of OF2 or 180F2 diluted in argon with a beam of Li, Na, K, or Mg atoms on a salt window at 15°K produces new infrared absorptions which are due to the appropriate metal fluorides. An intense absorption at 1028.6 cm-I is independent of the metal used to generate the reaction, and this feature shows the appropriate oxygen-IS shift for assignment to the OF free radical. Additional bands show a metal dependence and are attributed to weakly bonded MF·· ·OF dimers. Use of isotopic mixtures shows that bands at 714.0 and 417.5 cm-I using 6Li are due to a new species containing single lithium and oxygen atoms which concentration studies suggest to be the molecule LiOF.
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.
