Patient-centered approach can backfire
...eople's expectations aren't met, the psychological reaction
can be to try to restore control by doing your own thing, or even doing the opposite of what you're told," Christensen said. Patients at the other end of the spectrum - highly engaged, patient-centered patients treated by doctor-centered providers ...

does occur in nature only far more slowly, taking place over eons of time. Once the process is fully developed, it is estimated that the locking of CO2 will take place within minutes. The end product is a mineral such as magnesite, which can be ...

occurred when the stress was nonphysical, so we used the math test." The researchers found that both pistachio containing diets reduced the stress effects on blood pressure, but that the 1.5 ounce pistachio diet reduced systolic blood pressure by 4....
