Lecture or Listen: When Patients Waver on Meds

According to a new analysis of hundreds of recorded office visits, doctors and nurse practitioners typically issued orders and asked closed or leading questions when talking to their HIV-positive patients about adherence to antiretroviral therapy. Attempts at problem-solving with patients who had lapsed occurred in less than a quarter of visits

PROVIDENCE, R.I. [Brown University] — Take your medicine, Doctor’s orders. It’s a simple idea that may seem especially obvious when the pills are the antiretroviral (ARV) drugs that add decades to the lives of HIV-positive patients. But despite the reality that keeping up with drug regimens is not easy for many patients, a new analysis of hundreds of recorded doctor’s office visits finds that physicians and nurse practitioners often still rely on lecturing, ordering, and scolding rather than listening and problem solving with their patients.

ANN ARBOR, Mich.— Using a liquid laser, University of Michigan researchers have developed a better way to detect the slight genetic mutations that might predispose a person to a particular type of cancer or other diseases.

Their results are published in the current edition of the German journal Angewandte Chemie. (more…)

Researchers at Yale University have developed a new way of exposing the atomic attachments that keep complex molecules in precise alignment. The new method could provide insight into the mechanics of a variety of molecular structures, potentially aiding efforts to manipulate them for drug discovery and other purposes.

“The method appears likely to become a central tool for the characterization of processes that depend on supramolecular associations,” said Mark Johnson, a Yale chemistry professor and the principal investigator of the technique, which is described in a paper published this month in the journal Science. Supramolecular associations are interactions taking place between molecules, rather than within them. (more…)

ANN ARBOR, Mich.— Using Facebook and Twitter may be good for a company’s bottom line, but firms can rake in even bigger profits if they have their own virtual brand community, says a University of Michigan marketing professor. (more…)

The communities of marine microorganisms that make up half the biomass in the oceans and are responsible for half the photosynthesis the world over, mostly remain enigmatic. A few abundant groups have had their genomes described, but the natures and functions of the rest remain mysterious. (more…)

For his discoveries about the lives and deaths of stars, the exotic physics of black holes and the origin of chemical elements, UA Regents’ Professor David Arnett has been honored with the Henry Norris Russell Lectureship.

What happens when a star dies? How does a black hole form? What makes the chemical elements that form the building blocks of stars, planets and living beings? (more…)
